In the past, conservation effort has primarily focused on establishment of forest reserves for timber production, with minimal or no consideration to how these natural resources will help sustain or improve livelihoods of adjoining communities. This study examined the contribution of Aramoko forest reserve to the livelihoods of the adjoining communities in Ekiti State. One hundred and twenty pre-tested questionnaires were administered among the products collectors in the study area. Data collected were analysed and the result showed that 78.3 % of the respondents are married with 52.3 % of them male, while 50.8 % of the respondents aged between 51-70 years with 64.1 % having at least secondary education. Twenty-five (25) different products were collected by the respondents in the study area. These products include among others; timber with highest frequency of (120) followed by herbal plants (115), Archantina marginata (105), Thaumatococcus danielli (89), Bridelia ferruginea (70) and Irvingia garbonensis (65). The use of motor cycle accounted for 41.4 % of the respondents means of transportation, while 31.3 % of the respondents sell their product in bit at the village market. Picking, digging, plucking, cutting and uprooting were methods used for harvesting by the respondents while illegal felling (24 %) and indiscriminate bush burning (22.4 %) were the major conservation problem in the study area. Specifically, some of the products harvested are used for food, medicine, fuelwood, herbs and cultural purposes. The study recommends that research should be conducted into how these products can be artificially raised in the nursery for plantation establishment.


The focus of this case study is re-use in abstract algebra. It contains locale-based formalisations of selected parts of set, group and ring theory from Jacobson's Basic Algebra leading to the respective fundamental homomorphism theorems. The study is not intended as a library base for abstract algebra. It rather explores an approach towards abstract algebra in Isabelle. hide-const map hide-const partition no-notation divide (infixl ′/ 70 ) no-notation inverse-divide (infixl ′/ 70 ) Each statement in the formal text is annotated with the location of the originating statement in Jacobson's text [1]. Each fact that Jacobson states explicitly is marked as theorem unless it is translated to a sublocale declaration. Literal quotations from Jacobson's text are reproduced in double quotes. Auxiliary results needed for the formalisation that cannot be found in Jacobson's text are marked as lemma or are interpretations. Such results are annotated with the location of a related statement. For example, the introduction rule of a constant is annotated with the location of the definition of the corresponding operation. 1 Concepts from Set Theory.

Objective: Care of handicapped or elderly by the family members in the home environment brings not only many positives for the care recipients, but can also impose a significant burden on the caregiver. The goal of the study was to assess the caregiver burden, burnout syndrome and the effect of caregivers' sociodemographic characteristics. Design: Cross-sectional study. Participants: The sample consisted of 168 caregivers who took care of disabled children or seniors. Methods: Zarit Burden Interview identifying the subjective burden of informal caregivers, and Maslach Burnout Inventory assessing the burnout syndrome were used. Results: A higher level of caregiver burden and the development of burnout syndrome occurring most frequently in the dimensions of Emotional Exhaustion and Personal Accomplishment was observed. The caregiver burden was found to be lower in men, in caregivers living alone, and in the respondents from higher income households; it increased with the weekly amount of care. Conclusions: The results proof the demanding nature of informal care. A longitudinal study could illuminate the temporal changes in the family dynamics.


This paper presents numerical methods for solving turbulent and two‐phase transonic flow problems. The Navier–Stokes equations are solved using cell‐vertex Lax–Wendroff method with artificial dissipation or cell‐centred upwind method with Roe's Riemann solver and linear reconstruction. Due to a big difference of time scales in two‐phase flow of condensing steam a fractional step method is used. Test cases including 2D condensing flow in a nozzle and one‐phase transonic flow in a turbine cascade with transition to turbulence are presented. Copyright © 2005 John Wiley & Sons, Ltd.


Polymer closed cell foam beam specimens manufactured from H100 Divinycell (Diab) are tested in four point bend at three loading speeds using a specially designed rig and an Instron VHS test machine. Synchronised high speed images are captured using white light and infra-red thermography (IRT) to obtain the mid-point full-field deflection and strains using digital image correlation (DIC) along with the temperature evolutions. There is a marked increase in the maximum load to failure with loading rate and the optical techniques provide an opportunity to analyse the strain and temperature evolution within the specimens.


The main parameter that determines the state of the power transformers in operation, whether normal or deteriorating, is the insulation inside, composed of dielectric components such as oil and paper covering the winding enclosure. Abnormalities in insulation are products of degradation of the mentioned components; Forming chemical by-products that are derived from aging and accumulate in the oil in the form of gases, the main effect is the life of the transformers.
The most accepted and used method to detect gases inside a transformer is the Dissolved Gas Analysis (AGD), because it emits more information, allows to diagnose probable failures by means of conventional techniques of interpretation of results (gases in ppm) before Which is present in the machine, this type of fault is commonly known as "Incipient Failure".
In the present work, samples of the AGD were made to several power transformers submerged in oil (shown in Tables 9, 10, 11 and 12) to form a database (gas concentrations and fault diagnosed), evaluated and performed A diagnosis of the state to several power transformers based on intelligent methods of data interpretation for the prediction of failures, these are: Artificial Neural Networks and Vector Support Machines to compare them with the criteria scientifically accepted as: Criterion of Rogers and Criterion of Dornenburg , In order to determine the most assertive method to detect incipient faults in power transformers.


The purpose of the study is firstly to find out the students' learning outcomes in Social Science which has increased after the Concept Sentence Learning Model is applied. Secondly, it is to determine student learning activities in the learning process. This research is classroom action research. The subject of this study are Class V students of 162 Aek Marian State Elementary School with 14 male and 13 female students. The research instrument uses tests and field observations to obtain accurate data about the results and learning activities in the classroom. The results showed, firstly, there is an increase in learning outcomes in the pre-test from 0% to 59% in the cycle I which is included in the pass category with an average classical score of 67. Both results in the cycle II have a better increase in which the cycle II was 96% so that the result of the difference in the increase in cycle I and II is 37%. This increase in student learning outcomes proves that the application of the concept sentence learning model is effective in improving student learning outcomes.


Common mode current coupling to cables from power converter PCBs are commonly known to cause radiated emission problems at lower frequencies. This paper identifies the coupling path using a coupling coefficient method by the use of full wave simulation and successfully identified and reduces emissions at specific frequencies.


The objective of this article is to propose a revised conceptual framework for the analysis of the supply chains for cellular therapies that considers first the impact of supply and demand uncertainty on the supply chain pathway, and second the impact of complexity on the physical supply network configuration. We suggest a revised cellular therapeutics supply chain taxonomy that emphasizes the interdependence between product characteristics, supply chain pathway and network configuration, which we hope will facilitate structured thinking around the design of optimal supply chain strategies for different products.


This paper will describe a new measuring method for human dirt in textile based on Laser induced fluorescence (LIF). Typical standard cloth was used as a sample and synthesized sweat and human lipid was used as model dirt on the standard cloth. LIF spectra were measured by a developed measuring system. Appropriate calibration models to obtain the concentration of the dirt elements were studied. This paper also describes the application of this method to estimate the real human dirt that includes sweat and lipid.


Flow-induced vibration analysis of pipes conveying fluid has gained its attention as the pipes are widely used in many industrial areas. Over the last decades, many studies have been conducted on the dynamic characteristics of pipeline systems subject to different loading conditions. In this paper, the effect of the crack to the flow-induced vibration characteristics of the supported pipes is investigated. Previously, the crack identification algorithm for the rectangular beam has been developed and verified against the experimental as well as finite element analysis results. However, no published literatures have been found regarding the flow-induced vibration of pipes with crack case. A crack identification algorithm based on a mathematical model will be sought after based on this work to identify crack location and depth. In order to estimate crack location and depth in the pipe, we need to utilize the variation of the difference between the natural frequencies of the pipe conveying fluid with and without crack. The pipe is fluid loaded via interaction with the fluid. Fluid loading has two main effects on vibrating pipes: First, the fluid mass loads the pipe, meaning that the pipe's natural frequencies are altered due to added mass. Secondly, viscous loading is provided to the pipe near the wall due to shear force between the pipe and the fluid. In COMSOL Multiphysics®, the Aeroacoustics and Structural physics interfaces have been used for frequency domain analysis. Fully developed laminar velocity flow profile is used to simulate the fluid flow inside the pipe. Perfectly Matched Layer is used to simulate the unbounded boundary to purely capture the fluid and the pipe system without standing waves; hence the mode shapes are expected to remain unchanged for pipes conveying fluid from ones attained from pipes alone.


Notwithstanding its large internal diversity, of all continents Africa si undoubtedly the one whose future is the most affected by water issues, from a social and political standpoint as well as in terms of environmental and economic development. This paper underlines the importance of institutional capacity for integrated management of river basins. Strategic development issues such as food, agriculture, and public health are addressed through the challenges of providing access to clean drinking water and sanitation. Enormous resources and efforts at better governance are required. They demand a very urgent collective mobilization.


Figtree Place is a water sensitive urban redevelopment consisting of27 residential units located in Hamilton, an inner suburb of Newcastle, NSW, Australia. The site uses rainwater stored in tanks to supply hot water and toilet flushing demand. A two-year monitoring program for roofwater, tanks and hot water systems revealed that water quality improves in the roof to tank to hot water system treatment chain. Analysis of water quality from hot water systems and rainwater tanks showed compliance with the Australian Drinking Water Guidelines.

Color uniication is valuable for tracing, debugging, and understanding Prolog programs. However, color connicts can arise naturally during color uniication. This paper describes possible strategies to deal with these connicts. The advantages and disadvantages of the diierent strategies are discussed using examples generated by a working implementation. It is found that no single scheme works best in all situations, and that in many instances, more complex schemes have little advantage over simpler ones.


Porous scaffolds of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) were elaborated by three different techniques: salt leaching (SL), emulsion solvent evaporation (ESE) and temperature induced phase separation (TIPS). For SL partially fused sieved grains of sodium chloride (106-355 μm) were used as porogen. Emulsions, prepared from a solution of PHBV in chloroform allow getting flexible films; the content of surfactant may be used to control the pore size. The pore size of the TIPS scaffolds decreased on increasing the cooling rate and the morphology of the interconnected structure could be controlled by changing the temperature gradient. Finally, chemical changes associated to the enhancement of hydrophilic behaviour of the scaffolds after alkaline and enzymatic hydrolysis as well as after sterilization by γ irradiation are presented.

Folates exist as a fluctuating pool of polyglutamated metabolites that may serve as a clinical marker of methotrexate (MTX) activity. This study was undertaken to evaluate circulating folate content and folate polyglutamate distribution in juvenile idiopathic arthritis (JIA) patients and in a cell culture model based on MTX exposure and folate supply.


IT WOULD TAKE THE DEVIL'S OWN' TIME and tirelessness to track down all the United States terrain features (Rocks, Caves, Lakes, Dens, Punch Bowls, Tea Tables, Half Acres, etc.) listed either in his or in Hell's name. I myself, without going beyond standard road maps, guidebooks, and a random sample of toponymic treatises, have counted upwards of 350 such parcels of Satan's acknowledged property. In American onomastics the Devil not only owns a lot of the landscape; he even displays parts ofhis anatomy here and there for the tourist trade, e.g., humping up his Backbone in at least ten states, turning up his Nose in California and New York, poking out his Thumb from a mountain in Alaska and one of his Horns as a butte in Oregon, pricking up his Ears in North Dakota, bending his Elbow all over the continental United States. Americans' eagerness to give the Devil his due has even engendered some interstate rivalry, of which a couple of examples may be cited. Missouri, for instance, has its champion in R. L. Ramsay, who writes,


What do we want our students to learn from an experience? This is the central question that underpins learning objectives. Learning objectives attempt to describe the manifestations of learning that we would like to see by the end of a learning experience (e.g. a course or a learning module). Traditionally areas of knowledge that are the target of learning objectives are described as domains. Typically knowledge is described as cognitive, affective, or psychomotor and there are other domains such as interpersonal 1-4 . The domain describes the nature of the learning. Has the student learned a new cognitive process, or learned to care about something new? The organization of learning into these domains helps us to make sense of the types of knowledge that our students are learning. A domain is like a country, it defines a piece of the knowledge landscape. A taxonomy of learning attempts to map that landscape. It creates categories that describe ways of knowing. Just as a map describes the landscape using categories (e.g. roads, parks, towns), a taxonomy categorizes ways of knowing so that we can better define the manifestation of learning that we want our students to achieve. Most taxonomies are meant to be thorough maps of one domain. For example Bloom's taxonomy describes ways of knowing within the cognitive process domain 1 . It attempts to categorize all of the different levels of learning in this domain. When Anderson and Krathwohl later updated Bloom's taxonomy they added a second dimension, the knowledge dimension, which breaks apart the domain into 4 parts: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge 5 . Their taxonomy applies the same levels of learning (i.e. cognitive processes) to each of these four pieces of the domain. Bloom's (or Anderson's) do not describe everything that a student should learn. They are only meant to describe one type of learning: cognitive process. Other taxonomies map other domains and some taxonomies cut across domains.


Selective formation of porous silicon (PS) on both n-and p-type silicon wafers using silicon nitride deposited by PECVD and SU-8 photoresist is studied in this paper. Resistance of the silicon nitride to the HF etching can be enhanced by annealing at high temperature. The etching rate of the silicon nitride decreases from 50nm/min to 10nm/min when annealing the samples from 700/spl deg/C to 950/spl deg/C. The patterned PS areas were covered by a thin polyaniline layer doped with camphorsulphonic acid (CSA) to achieve a rectifying junction.


A recently developed wavelet based approach is employed to characterize the scaling behaviour of spectral fluctuations of random matrix ensembles, as well as complex atomic systems. Our study clearly reveals anti-persistent behaviour and supports the Fourier power spectral analysis. It also finds evidence for multi-fractal nature in the atomic spectra. The multi-resolution and localization nature of the discrete wavelets ideally characterizes the fluctuations in these time series, some of which are not stationary.


Author(s): Kurki-Suonio, H; Mathews, GJ; Fuller, GM | Abstract: We investigate the recently observed periodicity of the distribution of galaxies at high redshift by comparing the data with models in which galaxies reside on the surfaces of bubbles or sheets. A statistical analysis of the deviation from periodicity along various lines of sight seems to suggest that the data more closely resemble a regular cellular pattern in which the bubble centers are strongly anticorrelated than a distribution produced by random voids or sheets. We discuss how such a regular structure might arise and suggest some observational tests of this interpretation.


Introduction: The human face is a disconcerting source of information, since cultural influences, masculine-feminine characteristics, the aging process, the subtleties of light that change with the orientation of the face, rest, smiling and others configurations endow each particular face with a uniqueness that is difficult to quantify. The objective of this study was to determine whether or not there is a golden ratio between the intercanine distance and the vertical measurement of the midface of fourth-year students of the Faculty of Dentistry of the University of Cuenca. Methods: Descriptive, cross-sectional and randomized study. The sample consisted of 40 fourth-year students from the Faculty of Dentistry of the University of Cuenca, Ecuador. The observation technique was used. The following were observed and analyzed: 1) the intercanine distance and 2) the vertical measurement of the middle third of the face, to determine if there is a presence or absence of the golden ratio. Results: For the frequency of values about whether there is a Golden Ratio or not, it is shown that: in the intervals 2.65 - 12.90 mm (very close) there are 4 men with 13.33 % and 3 women with 6 00 %, in the interval 12.91 - 23.16 mm (close) there are 8 men with 26.66 % and 15 women with 30.00 %, and in the interval 23.27 - 33.52 mm (distant) there are 3 men with 10.00 % and 7 women with 14.00 %. Conclusion: It is observed that in 56.66 % of the fourth-year students of the Faculty of Dentistry of the University of Cuenca there is a close correlation to the golden ratio between the intercanine distance and the middle third of the face, this being the most representative of the three intervals analyzed (very close, close and distant).


REQUIRED) A decade ago, the microfinance industry prided itself on its trends toward financial and operational sustainability. Recently, investors, donors, lenders, regulators, and microfinance institutions have been more concerned with social and outreach performance. Transactions cost and distance theories inform a new ICT-enabled microfinance institution (MFI) outreach theory positing that information and communication technology (ICT) adoption among MFIs will result in direct improvements to MFI operations and a greater capacity for poverty and geographic outreach. These propositions are modeled using a case study methodology with primary research materials collected from 14 microfinance institutions in 8 countries. Using a pattern-matching mode of analysis, we find that different ICTs impact two types of outreach: geographic and poverty. Policy, database, and software-related ICT adoption activities impact poverty outreach due to their support of flexibility and information. Infrastructure, networking, hardware, and telephony ICT adoption activities impact geographic outreach since these areas support connectivity.


Does life sometimes looks like a movie? Or is it the movies that, however fantastic, are never as incredible as real life? Well, the process that led to the implementation in Porto, Portugal, of a technological spin-off on optical fiber sensors with a global vision looks a lot like one of those adventures that we think we can only live in a theater near you.

The effect of aeration rate on the efficiency of CANON(completely autotrophic nitrogen-removal over nitrite) process was studied to improve total nitrogen removal of ammonium-rich wastewater.With simulated wastewater as influent,two kinds of CANON reactors,which used sponge and modified polyethylene as carriers respectively,were studied in tests.The results showed that total nitrogen removal efficiency and removal load were closely related to aeration rate,the increase of aeration rate would improve total nitrogen removal of CANON reactor when aeration rate was less than the limiting aeration rate.For the CANON reactor which used sponge as carrier,when aeration rate was 35.8 m~3·m~(-3)·h~(-1),the total nitrogen removal efficiency reached the maximum value of 79.48%,and total nitrogen removal load was 2.32 kg·m~(-3)·d~(-1).When aeration rate was more than the limiting aeration rate,the effect on total nitrogen removal remained stable,because the structure of sponge protected the Anammox bacteria from inhibition by dissolved oxygen.With sponge as carrier,more biomass could be retained in the CANON reactor,especially for Anammox bacteria,which guaranteed the stable operation of the CANON reactor.For the CANON reactor which used modified polyethylene as carrier,when aeration rate was 6.3 m~3·m~(-3)·h~(-1),the total nitrogen removal efficiency reached the maximum value of 77.6%,and total nitrogen removal load was 1.01 kg·m~(-3)·d~(-1).When aeration rate was more than the limiting aeration rate,the effect on total nitrogen removal deteriorated because Anammox bacteria were inhibited by dissolved oxygen.Less biomass could be retained,so the reactor was less stable.


Anticancer activity of secang's heartwood ( Caesalpinia sappan L.) is based on its main compound: brazilin and brazilein. Brazilin, brazilein, and other compounds such as caesalpiniaphenol can affect proteins that have a role in apoptosis. In this study, we observed cytotoxic activity of fraction containing brazilein (FCB) alone or in combination with chemotherapeutic agent, cisplatin and the ability of the combination to induce apoptosis in T47D breast cancer cell lines. Cytotoxicity assay was determined using MTT assay, whereas the detection apoptosis induction was conducted using flow cytometry using Annexin-V and propidium iodide. FCB and cisplatin showed cytotoxic effect on T47D cells with IC 50 value of 68 µg/mL and 16 µM, respectively. Combination of FCB and cisplatin result synergistic combination at the concentration ratio of 1/2 IC 50 with CI value of 0.66. Its combination also able to induce apoptosis on T47D cell population 13% larger than the single treatment. Based on this study, we conclude that FCB is able to enhance the cytotoxic effects of cisplatin by inducing apoptosis. Keywords: Caesalpinia sappan L., cisplatin, apoptosis, breast cancer


This study was aimed to determine normal serum adenosine deaminase (ADA) activity in domestic animals in both sexes and that were considered healthy on the basis of clinical and laboratory examinations. In this study, 262 non-pregnant animals of both sexes, belonging to 5 species [cattle (n = 50), sheep (n = 65), goat (n = 52), dog (n = 55), and cat (n = 40)] were used. Serum total ADA and ADA1 isoenzyme activities were found to be 6.34 ± 0.31 IU/l and 6.34 ± 0.31 IU/l in cattle, 7.57 ± 0.30 IU/l and 7.31 ± 0.47 IU/l in sheep, 7.52 ± 0.36 IU/l and 6.44 ± 0.72 IU/l in goat, 2.56 ± 0.13 IU/l and 2.03 ± 0.30 IU/l in dogs, 23.36 ± 1.59 IU/l and 21.71 ± 2.13 IU/l in cats, respectively. The serum levels of ADA2 were low in sheep, goats, dogs, and cats, whereas in these species ADA1 was high. Furthermore, there was no serum ADA2 activity in cattle. Additionally, there were no significant differences between genders in ADA activities in all species. As a result, determination of serum normal ADA and its isoenzyme activities in domestic animals will be useful for scientists who want to investigate ADA activity in future in different diseases.


Large-scale programs to encourage vehicle-infrastructure cooperation such as VII in the United States and CVIS in Europe open the door to the availability of probe vehicle data of unprecedented richness for a variety of ITS applications. One of the primary challenges in developing these systems is defining an architecture for data aggregation that promotes efficient data backhaul, access and management. This paper shows how moderate local data aggregation could dramatically reduce the volume of data to be handled, reducing the costs of system implementation and of accessing the data to support end-user applications. For the covering abstract see E134653.


Theoretical fault models and computer simulations of fault slip can reveal the role and relative importance of different factors on the manner in which slip accumulates on faults. Such factors include various forms and parameters of friction laws, pore pressure evolution, and fault non-planarity. To study long deformation histories, most simulation methods do not incorporate full inertial effects during simulated fast slip. In quasi-static methods, a series of static problems is solved, with the loading advanced in time. However, such methods cannot simulate fast slip during seismic events, and earthquakes have to be added to such simulations in a kinematic fashion. That is why so-called quasi-dynamic methods have become increasingly popular, which approximately account for inertial effects (and hence seismic radiation) during simulated earthquakes through a radiation damping term. Such methods allow to continue simulations through the seismic phase, without having to pay significant additional memory and computational costs associated with modeling true wave-mediated effects. In this study, we compare the results of quasi-dynamic simulations and fully-dynamic ones, in with all wave effects are accounted for during simulated earthquakes. We consider the long-term fault 106 behavior in two problems: (i) interaction of two velocity-weakening regions separated by a small velocity-strengthening patch and (ii) segments with additional pronounced rate-weakening during seismic slip. We find that, in the absence of additional seismic weakening, the two methods generally result in the same qualitative behavior, with similar slip patterns, although there are quantitative differences. In fact, in quasi-dynamic simulation, resulting seismic events tend to have much slower slip velocity and rupture speeds which may modify significantly the resulting seismic events and hence the long-term fault behavior. In simulations with additional coseismic rate weakening, the two methods produce qualitatively different long-term results with different slip patterns. Fullydynamic solution generates pulse-like events, while quasi-dynamic formulation turns earthquakes to be more crack-like. Moreover, we observe that the levels of shear stress on the fault is significant different in both cases. In fully-dynamic simulations seismic events are able to nucleate and to propagate through the fault at a much lower level of shear stress than for quasi-dynamic ones.


For civil engineering specialty, this article expounds a kind of resource development thinking that is based on the combination of Internet and virtual technology. And the development and application of professional core curriculum teaching resources are practiced. In the process of research, we developed curriculum resources using vitual technology and built a Large-scale online open course platform. The teaching mode of "virtuality and reality combination, online and offline" and the learning mode of "theory with practice integration, in class and outside" were applied. And we practiced "networked timely tracking and evaluation".


A malignant neoplasm is abnormal cell growth in a tissue and affect human quality of life and lifespan. Lung cancer was the second most commonly estimated cancer case and the first leading cause of cancer death both in human. Therefore, lung cancer brought out over one million death worldwide each year. However, in the era of medical technology developed, the five-year relative survival rates of lung cancer, especially in advanced stage, would not significantly improve. Various chemotherapeutic drugs, such as cisplatin, were widely accepted as a standard first-line treatment for advanced NSCLC (non-small cell lung cancer). However, cisplatin performs excellent treatment, but the drug resistance may be the major obstacle to affect the treatment. This study proposed a micro-emulsion method to synthesize cisplatin-loaded magnetite-hydroxyapatite nanoparticles (mHAp/CDDP) to combine chemotherapy and hyperthermia in one nanoparticle system for lung cancer therapy. Magnetite can act as a thermal seed under an alternating magnetic field for hyperthermia. The loading efficiency of the cisplatin in the synthesized nanoparticles was 22.9%. The major phase of the synthesized mHAP/CDDP nanoparticle was identified as hydroxyapatite by XRD; with where the magnetite and CDDP crystal were precipitated on the surface of hydroxyapatite along [211] and [200], respectively. The individual grain size of synthetic nanoparticles were in the range of 50-80 nm directly under TEM examination. The magnetic particles revealed a superparamagnetic property by SQUID; that could induce heat generation within minutes by an external alternating magnetic field and can be used for hyperthermia application. Moreover, the synthesized nanoparticle can be engulfed by A549 cells through endocytosis process. Therefore, hydroxyapatite can be dissolved in endosome-lysosome hybrid which would be breakdown by osmotic pressure and then cisplatin would escape from the vesicles into nucleus leading A549 cells toward apoptosis via ERK signaling pathway. Based on the results of in vitro and in vivo studies, to combine hyperthermia and chemotherapy in mHAp/CDDP nanoparticle could provide synergistic effect to inhibit A549 proliferation and tumor growth. We believed that the mHAp/CDDP nanoparticles have great potential on lung cancer treatment.


The use of Electronic Health Records (EHR) for reporting patient data has been widely adopted by healthcare providers. This data can encompass many forms of medical information such as disease symptoms, results from laboratory tests, ICD-10 classes and other information from patients. Structured EHR data is often high-dimensional and contain many missing values, which impose a complication to many computing problems. Detecting meaningful structures in EHR data could provide meaningful insights in diagnose detection and in development of medical decision support systems. In this work, a subset of EHR data from patient questionnaires is explored through two well known clustering algorithms: K-Means and Agglomerative Hierarchical. The algorithms were tested on different types of data, primarily raw data and data where missing values have been imputed using different imputation techniques. The primary evaluation index for the clustering algorithms was the silhouette value using euclidean and cosine distance measures. The result showed that natural groupings most likely exist in the data set. Hierarchical clustering created higher quality clusters than k-means, and the cosine measure yielded a good interpretation of distance. The data imputation imposed large effects to the data and likewise to the clustering results, and other or more sophisticated techniques are needed for handling missing values in the data set.


Israel's great inflation is defined as an annual rate of two or three digits. This developed in the 1970s and accelerated until 1985. In the second quarter of 1985, the annualized rate reached 400%; in the second half of that year it was brought down to an annualized rate of 20%. The first half of the book analyzes the way in which inflation was allowed to accelerate between 1970 and 1973. Although the period 1967-1973 was one of fast economic growth, Barkai asserts that the rise of inflation from negligible rates at the end of 1969 to 20% (annualized) just before the October 1973 War was a major policy failure. The main cause was excess demand due to expansionary fiscal and monetary policies. Although external factors, such as the rise in oil prices, played a role, the main culprits were the government and central bank. Barkai shows how complex the interpretation of economic data can be. During early 1973, for example, "fiscal policy was highly expansionary, indeed much more so than the information available to the political leadership might have suggested" (p. 80). Barkai also shows how economic policy related to the fraught military and political position in a country at war, or nearly at war. He places economic thinking in Israel in its international context by discussing the role of the Phillips curve. This meant that, in terms of the thinking of the 1970s, politicians choosing growth and full employment were justified in neglecting inflation. The second half of the book does not follow from the first. It begins with a comparison of the economic stabilization programs of Argentina, Brazil and Israel that were all implemented in 1985-1986. The relative success of the Israeli program is explained by the tough fiscal and monetary policies. Then follows an analysis of the Israeli program, the most important aspect of which, in Barkai's view, was its comprehensiveness. It succeeded despite the fact that the elaborate system of linkage was not broken. An analysis of what happened to the economy between 1973 and 1985, when inflation went from double to triple digits, is glaringly missing. Is the implication that the author does not think this period and what happened in it is unimportant? Only with supplementary reading will the full story become clear. Those who want to fill the gap are recommended to read Michael Bruno's Crisis Stabilization and Economic Reform: Therapy Consensus (Oxford, 1993). PAUL RIVLIN


In the advent of realising Level 3 autonomous driving, the race of cities towards achieving Smart Mobility has recently escalated with promises of green, accessible, affordable, efficient, and ethical transport. Thus, the paradigm of smart mobility is intertwined with the challenges of autonomous driving and these are best addressed jointly. At the same time, breakthrough advances in artificial intelligence innovations have transformed the dream of autonomous driving to a near future tangible possibility. The challenges of scalability, accountability, trust, and incurred cost are nonetheless hindering the speedy deployment of the autonomous driving features and the societal acceptance of such technologies. In this paper, we offer an indepth analysis of the Smart Mobility and autonomous driving state of the art technologies and identify the mainstream trends and shortcomings. Furthermore, we offer a new hybrid ecosystem that curtails these obstacles and unlocks the potentials of smart mobility by creating the ubiquitous Swarm Wisdom.


Technological globalization has accelerated at an increasing rate in recent decades. The trend stems from the emergence of new innovations and new technologies such as the Internet. Today, technology development is seldom confined within single countries; on the contrary, multinational collaboration has become the norm. Companies working in this new environment must utilize both domestic and foreign intellects and speed up innovation through international collaboration. Taking the case of Russia and Japan as an example, this report investigates the possibility of joint creation through effective knowledge management, such as knowledge identification, utilization and transfer. Here, some explanatory cases are introduced, as Russian knowledge is identified and transferred through the mediums of licensing, joint ventures, and joint development projects between corporations and other organizations in the two countries. Thus the report proposes the ideal way of collaboration with a new market and advanced industrial countries, with effective frameworks for new forms of technological development between these economies. For example, Japan is strong in production and quality control, while Russia has high potential in basic research. Given the level of technological expertise in Japan and East Asia, and the nature of the scientific expertise in Russia, we can create a strong basis for collaboration. This new business model linking Japan and Russia could generate a unique synergy, with each nation offsetting the weaknesses and complementing the strengths of the other. Collaboration between the countries has the potential to reward both countries and contribute to the global economy.

Background. The proliferative activity of tumors has been extensively investigated with different approaches, among which the use of the monoclonal antibody Ki‐67 represents an easy and reliable means of assessing cell proliferation. In this study, the proliferative activity of 129 primary breast cancers was investigated, and the results were related to prognosis.


The proliferation and migration of porcine adipose-derived stem cells (ASCs) have only begun to be studied in detail in vitro. The primary aim of these studies was to analyse in vitro ASC migration in varying concentrations of growth factors derived from the platelet-rich fraction of centrifuged plasma, the so-called platelet-rich plasma (PRP). ASCs were hypothesized to migrate at a faster velocity with increasing PRP concentrations. Whole blood was collected with a sodium citrate anticoagulant and subjected to two centrifugations. The first slower spin was to remove red blood cells to collect plasma, and the second faster spin was to collect the fraction with a high platelet concentration. Platelet concentration increased 3.5-fold compared to plasma, within the prescribed therapeutic range. For long-term culture of ASCs, DMEM supplemented with no more than 20% was necessary to maintain cell viability. ASC proliferation rate in PRP-supplemented media was comparable to that in fetal bovine serum (FBS), a standard cell culture media supplement. In addition, the velocity of ASC migration increased in cultures supplemented with 10%, 20% or 30% PRP. Generally, PRP was determined to be a media supplement with similar effects as FBS, potentially making it a suitable substitute for in vitro expansion of ASC populations. These results are likely partly explained by similarities in growth factor concentrations and their effects. Further characterization of PRP will be necessary to tease out the specific growth factor(s) responsible for the increase in swine ASC migration.


As in Marvelous and Macho as in Leon's younger brother Michael, a name I learned in Catholic school. Saint Michael of the mat, of the left hook and the deafening blow, of teeth glistening as they made their arc to the laps of women sitting ringside. You don't like to see a man get knocked out cold? Then you've never lived in Hartford or any town of boarded windows. Have you ever gotten hit or thrown against a wall? There's a sweetness to it, that moment when your God would forgive you anything. One punch free as yesterday's papers. Marvelous the way his body moved on the TV screen. And me? I moved around the room, bobbed and weaved. I learned to hold my breath so I could fight with my head held under water.

Recently, Kolodziej proved that, on a compact Kähler manifold M, the solutions to the complex Monge–Ampère equation with right-hand side in L p , p > 1 , are Hölder continuous with exponent depending on M and ‖ f ‖ p (see [ Math. Ann. , 342, 379 (2008)]). Then, by using the regularization techniques from [ J. Algebr. Geom. , 1, 361 (1992)], the authors of [ J. Eur. Math. Soc. , 16, 619–647 (2014)] determined the optimal exponent of the solutions. We construct a cover of the compact Kähler manifold M that depends only on the curvature of M. Then, as an application, based on the arguments from [ Math. Ann. , 342, 379 (2008)], we show that the solutions are Hölder continuous with exponent that depends just on the function f on the right-hand side and the upper bound of the curvature of M.


To the Editor — The coronavirus disease 2019 (COVID-19) pandemic has created unprecedented challenges for infection prevention experts, healthcare providers, and hospital administrative personnel. National, state, and local hospital leaders have had to rap-idly adapt and update policies based on personal protective equip-ment and testing constraints. More recently, emerging data on presymptomatic transmission and prolonged viral shedding have created additional challenges. 1 ‐ 3 As the pandemic continues and states begin to allow easing of nonemergent surgery restrictions, stakeholders are now faced with the task of developing policies for surgeries on recovered COVID-19 – positive patients. Based on current data for COVID-19 and prior research on viral respiratory illnesses, we propose a rational surgical policy for such patients. Most concerns with regard to surgery in recovered COVID-19 positive patients are related to the uncertainty of the postsympto-matic infectious period. Several studies have demonstrated prolonged or intermittent viral shedding in otherwise recovered, asymptomatic patients. at after symptom and at after 4


The ability to react on and adapt to challenges of the working environment is important and desired characteristic of modern knowledge-based systems. Knowledge extraction from different data sources and representation of heterogeneous knowledge are illustrative examples of such challenges. For effective solving of these tasks knowledge-based systems should be able to generate (create) new classes of objects dynamically, when required. Therefore, the algorithms for dynamic creation of new classes of objects via computing the homogeneous and inhomogeneous intersection of homogeneous and inhomogeneous classes of objects are proposed in the paper. New classes of objects, established via proposed algorithms, define set of types, which determine heterogeneous collections of objects. Proposed approach provides an ability to check the existence of common parts for different classes of objects and to create new classes of objects dynamically, based on previously defined ones. Classes, created using proposed approach, could be integrated within the knowledge base and used for further construction of conceptual hierarchies.


EFHC1 gene mutations have been described in patients with juvenile myoclonic epilepsy (JME) and other types of idiopathic generalized epilepsy. We generated Efhc1-defi cient mouse and found that the mouse showed spontaneous myoclonus and increased susceptibility to a convulsant, pentylenetetrazol, further supported and confi rmed that EFHC1 is the gene for JME. Myoclonin1 protein encoded by EFHC1 is well expressed in prenatal choroid plexus and postnatal ependymal cell cilia. In consistent with this, the Efhc1-defi cient mouse showed slowed beating frequency of ependymal cilia and enlarged ventricles. Recent report also described that myoclonin1 was expressed in neurons and their mitotic spindles and midbody, but our re-investigation suggested that those signals in neurons were non-specifi c.


Terrestrial(3D) laser scanning has been used to restore of cultural property, construction, 3D model design of building. Recent terrestrial laser scanning techniques are being utilized in freeform building with complex geometric 3D model design. At this time, the high geometric accuracy of the laser scanning is very important. Therefore in this research, It was verified the freeform building applicability of high quality 3D models from a variety of 3D laser scanning for accuracy assessment.


Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19), which has spread worldwide and reached a pandemic level within several months (Bedford et al., 2020; Li et al., 2020; Hu et al., 2021). Globally, scientists are trying to understand and defeat COVID-19 using animal studies to explore potential therapeutics. Vaccination remains the best choice to protect susceptible populations; therefore, many institutions and companies have developed vaccines against SARS-CoV-2 infection and many therapeutics are under clinical investigations. For these undertakings, it is essential to use suitable COVID-19 animal models (Caldera-Crespo et al., 2021; Munoz-Fontela et al., 2022).


Introduction Colorectal cancer (CRC) in Podkarpackie in Poland is the third most common cancer in males (12.6% cancer diagnoses), and second among women (10.1% of recognised cancers). Aim An analysis of the trends in CRC incidence in the years 1963-2014 in Podkarpackie in the south-east of Poland. Material and methods A total of 19,460 CRC cases recorded in the period 1963–2014 in the National Cancer Registry as ICD C18-C21 cases were analysed. Results The overall cancer incidence rate in Podkarpackie Province was 20.4 in men and 16.8 in women per 100 thousand, and was lower than the Polish population by 12.4% for men and by 17.6% for women, respectively, in comparison to general Polish population rates. The mean age of CRC diagnosis grew from 64.0 years in males and 64.5 years in females in 1963–1969 to 67.6 and 68.4 years in 2010–2014, respectively. Conclusions In 1964–2014 the CRC incidence rate in the Podkarpackie region increased 12.7-fold in males and 8.1-fold in females. There was an observed stable growth of average annual increase in the CRC incidence rate in men in 1963–1999, but since 2000 a decline in this rate has been observed. In females there was a tendency towards increased average CRC incidence rate in Podkarpackie since 2000, while in the whole country the female population presented a stable decrease of this coefficient.


Software architecture recovery techniques are often adopted to derive a module view of software from its source code in case software architecture documents are unavailable or outdated. The module view is one of the most important perspectives of software architecture. In this paper, we propose a novel approach to derive a module view by adaptively integrating structural dependency and textual similarity. Our approach utilizes Newman modularity and Shannon information entropy to determine the appropriate weights of the dependencies during the integration. We apply our approach to various open-source projects and show the experimental results validating the effectiveness of the approach. key words: software architecture recovery, module view, dependency, Newman modularity, information entropy


In iron-based superconductors, the interplay between nematicity, magnetism, and superconductivity is still not fully understood. Experimentally, the isoelectronic series FeSe${}_{1-x}$S${}_{x}$ provides an ideal playground to tune different electronic ground states and to selectively investigate their mutual interplay. Here, the authors use high-resolution angle-resolved photoemission spectroscopy to compare the electronic structure of different single crystals in the tetragonal phase. They find that in the absence of nematicity and magnetism, the substantial reduction of electronic correlations correlates with the decrease of the superconducting transition temperature from FeSe to FeS.


This paper announces a new three-dimensional multistable chaotic jerk system with two saddle-foci equilibrium points and gives a dynamic analysis of the properties of the jerk system such as Lyapunov exponents, phase portraits, equilibrium points and bifurcation analysis. Chaotic jerk systems have a nice triangular structure in their dynamics and they have many engineering applications. Our new jerk system is obtained by modifying the dynamics of the Genesio-Tesi chaotic jerk system (1992), and our jerk system has two quadratic nonlinearities in total. The new jerk system has multistability with coexisting attractors. Also, the new jerk system is dissipative and has high complexity. As an engineering application, new synchronization results based on active backstepping control are also derived for the new jerk system. In addition, an electronic circuit implementation of the new jerk system is designed and implemented in MultiSIM. A good qualitative agreement has been shown between the MATLAB simulations of the theoretical chaotic jerk model and the MultiSIM results


Dispositional essentialists are typically committed to two claims: that properties are individuated by their causal role ('causal structuralism'), and that natural necessity is to be explained by appeal to these causal roles ('dispositional actualism'). I argue that these two claims cannot be simultaneously maintained; and that the correct response is to deny dispositional actualism. Causal structuralism remains an attractive position, but doesn't in fact provide much support for dispositional essentialism.


DNA molecules are the building blocks of life. In the last few decades, the fields of biotechnology and molecular biology have made significant progress. Computer scientists have used the storage capacity and massive parallelism of DNA molecules in order to build computing devices and investigated the computing powers of these models and their efficiency in solving computational hard problems. In this paper, we investigate Szilard / control languages of a new type of computing model where the underlying model is based on the working of DNA molecules. DNA molecules are double-stranded and contain chains of nucleotides. These nucleotides are characterized into four types, i.e., A (adenine), T (thymine), G (guanine) and C (cytosine) based on their chemical bases. Furthermore, these nucleotides follow Watson-Crick complementary, i.e., A-T and G-C pairing. We derive the Szilard / control languages of Watson-crick (WK) grammars. Also, we compare the family of Szilard / control languages of these systems with the family of languages such as REG, CF and RE.


In this study, we model the bus scheduling problem considering transfer synchronizations. Our mathematical model accounts for the variability of the travel and dwell times of bus trips, the regularity of individual bus lines, and the regulatory constraints related to the schedule sliding prevention and the layover time limits. To perform a synchronization of multiple bus lines that is robust to travel time and dwell time variabilities, we tackle this problem using the minimax decision rule of 2-player games where one player selects the optimal dispatching times for some specific travel and dwell time noise, whereas the other player selects the worst-case travel and dwell time noise for a given dispatching time solution. In a validation of this approach in two bus lines in Stockholm using 1 month of actual vehicle location and passenger counting data, we demonstrate the potential improvement in terms of service regularity and increased synchronizations. Finally, we examine how the performance of bus schedules in common-case scenarios is affected when their robustness to extreme deviations is increased.


Abstract We study the modularity of Ramanujan's function k ( τ ) = r ( τ ) r 2 ( 2 τ ) k(\tau )=r(\tau ){r}^{2}(2\tau ) , where r ( τ ) r(\tau ) is the Rogers-Ramanujan continued fraction. We first find the modular equation of k ( τ ) k(\tau ) of "an" level, and we obtain some symmetry relations and some congruence relations which are satisfied by the modular equations; these relations are quite useful for reduction of the computation cost for finding the modular equations. We also show that for some τ \tau in an imaginary quadratic field, the value k ( τ ) k(\tau ) generates the ray class field over an imaginary quadratic field modulo 10; this is because the function k is a generator of the field of the modular function on Γ 1 ( 10 ) {{\mathrm{\Gamma}}}_{1}(10) . Furthermore, we suggest a rather optimal way of evaluating the singular values of k ( τ ) k(\tau ) using the modular equations in the following two ways: one is that if j ( τ ) j(\tau ) is the elliptic modular function, then one can explicitly evaluate the value k ( τ ) k(\tau ) , and the other is that once the value k ( τ ) k(\tau ) is given, we can obtain the value k ( r τ ) k(r\tau ) for any positive rational number r immediately.


This essay focuses attention on aspects of border politics that give evidence of nation-building and national consolidation processes in Central Europe. In a normative, policy-oriented sense this is a question of borders as framing conditions for regional development. In a more critical and analytical sense this involves interrogating the actual use of borders in politically and ideologically framing national interests within a wider European context. The essay begins with a brief discussion of Europeanisation processes understood in terms of the promotion of cross-border cooperation (CBC) in Central Europe. Here, the significance of national structural conditions for implementation of Cohesion and regional policies and hence CBC will be discussed. One result that emerges is that while EU-European principles of cross-border cooperation have been partly mainstreamed into regional development policies they have at the same time been superimposed by the domestication of EU policies in the interest of nation-building. More specific evidence is then provided by Hungarian experience where national scale and nation-building have played key roles in conditioning the quality of cross-border cooperation and in the framing of state borders as resources. Attention will focus on: (1) Hungarian exploitation of CBC in the service of ethnopolitical development objectives and (2) Hungary's recent policy of border securitisation which essentially entails a re-nationalisation of its border regime and a framing of the physical border as a protective barrier against threats to national and European identity.


In this paper we describe "Diversity and Connection in CSTEM" project that is currently being implemented at LaGuardia Community College. This faculty-driven integrated project targets diverse student population in Computer Science, Technology, Engineering, and Mathematics aiming to advance their engagement, connection, and retention in CSTEM. The project's implementation, empowered by pedagogy of integration and technology-intensive educational experiences, cuts across several categories: (a) experiential learning through undergraduate course-based, learning, and research projects that are incremental in their difficulty; (b) social learning with innovative technology/Web 2.0 resources and projects in gateway to CSTEM courses; (c) talks/discussions involving women and other underrepresented groups in CSTEM; (d) professional development for faculty. The authors hypothesize that integration of the proposed activities will help students solidify their knowledge acquired in CSTEM courses, build new skills needed for CSTEM workforce, increase self-confidence and awareness of CSTEM fields, and connect to each other and faculty.


OF THE DISSERTATION Hodge Theoretic Compactification of Period Maps by Haohua Deng Doctor of Philosophy in Mathematics Washington University in St. Louis, 2022 Matt Kerr, Chair In this article, we review some aspects regarding Hodge-theoretic completion and boundary behavior of period maps. First, we recall some classical results on compactification of classical period domains e.g. Baily-Borel, Ash-Mumford-Rapoport-Thai. The works produced by Kato-Usui aims at generalizing Mumford's toroidal compactification to nonclassical period domain, which depends on construction of a strongly compatible fan. We prove such a fan can not exists universally, but for a single geometric variation of Hodge structure. We proceed such a construction on a 2-parameter geometric variation coming from Hosono-Takagi's family of Calabi-Yau threefolds of type (1, 2, 2, 1). Moreover, we briefly review the concept of eigenspectra, which is directly generated from Steenbrink's spectral theory on vanishing cohomology. We show by an example on how to compute the eigenspectra associated to a family.


A mathematical model is constructed to study the MHD peristaltic flow of a viscoelastic fluid with fractional Maxwell model under physiological flow constraints (creeping flow) viz low Reynolds number and long wavelength approximations. Homotopy Perturbation Method (HPM) is employed to find out the approximate solution of fractional differential equation (FDE). The effects of involved physical parameters, who define the fluid properties, on volumetric flow rate, pressure, and frictional force have been emphasized. Numerical results and simulation have been done by Mathematica Software and discussed with the help of illustrations. On the basis of this study one can make an important conjecture that when the pressure is more for Newtonian fluid in compare to viscoelastic fluid and it is also more for viscoelastic fluid with Maxwell model in compare to viscoelastic fluid with fractional Maxwell model in pumping region, in free pumping region it is same and in co-pumping region reverse trend is noticed.  This model is applicable to study the food transportation in digestive system and bio-rheology.


Information about objects that split or merge is often generated dynamically as a by-product of computation or in the observation of real-world behavior. Visualization tools for such processes must not only reveal temporal patterns and spatial organization but should also accommodate on-the-fly generation of split?merge information. This paper develops a formal structure for split?merge processes that provides a suitable underpinning for dynamic visualization tools. The structure allows split?merge processes to be constructed dynamically and supports operations such as concatenation and partitioning while maintaining the underlying split?merge structure. The paper also proposes a method for abstracting split?merge substructure to assist in the visualization of large systems. The abstractions can be used to produce visual simplification and to guide layout heuristics in producing better visualizations. The implications of visualizing split?merge processes with time lines are explored. Auxiliary visualization strategies based on dynamic boxes and tree rings are introduced to enhance information content of focus areas in larger time-line visualizations. The concepts are illustrated using data from timings of a network protocol and from the detection of patterns in scientific video data.


Controlled pore glass (CPG) chromatography was employed to simply (one pass through column) and rapidly (60 minutes) purify a human brain specific protein having a high molecular weight (approximately 250,000 mol. wt.) from a crude brain extract containing proteins of varying molecular weights. This method, either exactly as described herein or by adjusting the pore size of the CPG, should be adaptable to other purification problems.


Emission of parametric X-rays (PXR) in a multi-wave mode can provide its significant spectral-angular density increase. Distinctive features of multi-wave PXR generation were studied both theoretically and experimentally for high energies of electrons. The paper describes the main features of multi-wave PXR distributions and presents results of calculations showing that multi-wave generation mode can be observed also at low energy electron beams.


We experimentally demonstrate nanostructured silicon photodetectors which consist of subwavelength arrays of verticallyoriented waveguides etched into a P-I-N photodiode. Our device combines both spectral-filtering and photocurrentgeneration in one all-Si structure. We show that absorption and responsivity spectra of these nanophotonic devices can be tuned by appropriate geometric design.


A community framework comprises a main server, sub-servers and user clients. The user client is used for sending an authentication request to the main server to log in a community related to the corresponding sub-server, wherein every sub-server corresponds to one community. The main server is used for authenticating a registered identity of a user and allows a registered user to log in a corresponding community according to the authentication request. The user client is also used for communication with a user client of a communication object in the same community through a corresponding sub-server after logging in the corresponding community. Data of communication between user clients in the same community is managed by a corresponding sub-server, and communication data between the communities is independent of each other and is transmitted without passing through the main server, so that the privacy and security of internal communications data of every community can be ensured even if failure or hacking of the main server or internal staff leakage occur. The invention also relates to a related method and a system.


analized: insulin signaling pathway, endocannabinoid signaling pathway and total and phosphorylated forms of tau. Also, expression of proteins linked to neuroinflammation were analyzed. Data indicate that high fat diet exposure resulted in altered cognition and expression of tau and proteins partaking to insulin and endocannabinoid pathway in the hippocampus, resulting in neuroinflammation. On the other hand, treatment with D-pinitol ameliorated cognitive capacity and restored the alterations in protein signaling.


We explore the impact of cosmic rays (CRs) on cosmological adaptive-mesh refinement simulations of a forming 10^12 Msolar halo, focusing on the circumgalactic medium (CGM), and its resulting low-redshift structure and composition. In contrast to a run with star formation and energetic feedback but no CRs, the CR-inclusive runs feature a CGM substantially enriched with CRs and with metals to roughly 0.1 Zsolar, thanks to robust, persistent outflows from the disk. The CR-inclusive CGMs also feature more diffuse gas at lower temperatures, down to 10^4 K, than the non-CR run, with diffuse material often receiving a majority of its pressure support from the CR proton fluid. We compare to recent observations of the CGM of L ~ L* galaxies at low redshift, including UV absorption lines within background quasar spectra. The combination of metal-enriched, CR-driven winds and large swaths of CR pressure-supported, cooler diffuse gas leads to a CGM that provides a better match to data from COS-Halos (for HI, SiIV, CIII and OVI) than the non-CR run. We also compare our models to recent, preliminary observations of diffuse gamma-ray emission in local group halos. For our lower CR-diffusion runs with kappa_CR in the range 0.3 to 1 x 10^28 cm^2/s, the CR enriched CGM produces an inconsistently high level of gamma emission. But the model with a relatively high kappa_CR = 3 x 10^28 cm^2/s provided a gamma-ray luminosity consistent with the extra-galactic gamma-ray background observed by FERMI and roughly consistent with preliminary measures of the emission from M31's CGM.


The contents of rare earth elements of 11 coal samples in Huaibei Coalfield have been determined by INAA (Instrumental Neutron Activation Analysis) method, and the geochemistry of REE was discussed in this paper. The results show thatΣ REE is 81.95μ g/g in average, and REE distribution pattern is characterized by a" V-shape" curve with obviously Eu negative anomaly and with enrichment of LREE. In regard to the correlation analysis and cluster analysis,Σ REE has a close relationship with coal ash and elements of terrigenous clastics (Si, Al, Ti, Cr, Co, Ni, Th, Ta, Sc, Rb, etc) instead of the elements of marine environment (Ca, Sr, etc). Contents of REE increase with the increasing density of the fractions of samples. The uniformity of REE distribution patterns in the gravity fractions may provide evidence for the same source of REE. The REE-bearing mineral matter in coals is mainly supplied from terrigenous clastics. REE in coals is mainly concentrated in clay minerals instead of quartz, and the main occurrence is in kaolinite. The similarity about REE feature between coal samples and Late Paleozoic sediments in North China Platform reveals that the distribution pattern and Eu anomaly of coal samples are inherited by the source rock. The peat swamp environment has no effective influence on depletion of Ce because little seawater may invade peat swamp.


In 2016 the Accreditation Council for Graduate Medical Education (ACGME) Clinical Learning Environment Review (CLER) Program launched Pursuing Excellence in Clinical Learning Environments (Pursuing Excellence), an initiative to cultivate leaders who would innovate and transform the clinical learning environment (CLE) to improve patient care and the learner experience. One of the main components of this initiative was a 4-year Collaborative called the Pathway Innovators—comprised of a group of teams from 8 Sponsoring Institutions seeking to develop and test new approaches to enhancing integration of health care delivery systems and graduate medical education (GME). This article is the fourth in a 6-part series to chronicle the processes, work, and outcomes of the Pathway Innovators. Collectively, this series will provide an overview of the initiative, detail work on 4 primary drivers serving as the conceptual framework, and outline the initial approach to evaluation. This article focuses on the third driver of the conceptual framework: innovations in faculty development related to quality, safety, equity, and value.

To assess studies which compare or recommend perinatal methods of treatment or management, all such studies (86) published in 1979 in J. Pediatrics, Pediatrics, Am. J. Ob.Gyn, and Ob.Gyn.were reviewed independently by one of two neonatologists and one of two biostatisticians. A 5 page evaluation form was completed by each reviewer. Items noted by both reviewers included prospective design (48%), predetermined criteria for study completion (3%), adequate number of subjects (15%), adequate description of subjects (39%), clear indications for treatment (47%), use of blinding when feasible (36%), evaluation of treatment hazards (45%), and use of a randomized trial to support treatment recommendations (22%). Both reviewers considered the treatment recommendations fully justified in 10% of articles and partially justified in 69%. An overall score was calculated based on the 34 items considered most important to a well executed study. Despite disagreement on individual items, the total score for important items was highly correlated (r=.99). The mean score for all studies was 16.9 for biostatisticians (SD=6.5) and 17.2 for neonatologists (SD=6.5). The range was 3 to 32. Despite tragic past errors in the use of diethylstilbestrol, oxygen, sulfonamide, and chloramphenicol, poorly designed and executed studies are often the basis for therapeutic recommendations in perinatal medicine.


This article characterizes politics, philosophy, and economics (PPE) as a substantive research programme as a flexible and analytic debate on the relations between the individual and society that incorporates both positive and normative analyses. This, in contrast to a view of PPE as a series of interdisciplinary or multidisciplinary topics. To this end, I sketch the general shape of the research programme, it boundaries and its features, before offering a slightly more detailed account of some aspects of the PPE programme. I also defend the claim that there is some value in recognizing PPE as a research programme, and after discussing the conditions required for the programme to thrive, suggest that there is some reason to be concerned for its future.


In 1951, the San Francisco Bay Area suburb of Walnut Creek welcomed the construction of a major shopping center adjacent to their downtown area—a configuration that would lead municipal planners to prioritize retail development for their city. Walnut Creek's nonlinear path to retail dominance over the next several decades exemplifies not only the increasingly multivariate climate surrounding suburban retail development in the latter half of the twentieth century but also the increasingly autonomous role of municipal planners who have used retail as a versatile component of suburban spatial development in an age of metropolitan flux.


On the mode of education,the hidden reading was an adult-education in the Tang dynasty,and had self-reading characteristics.Meanwhile,it was an important part of private learning.The prevalence of reading hidden mainly lied in official educational declining and the prosperity of the imperial examination system.When the people wanted to read,they always got together in the famous mountains or convenient transportations and often learned Confucianism books and some poetry books.Sometimes they might write poems in ttemple.In addition,this kind of study had great impact on the appearance of college education of Song dynasty.


Introduction Following a Mediterranean dietary pattern may improve health outcomes of men with prostate cancer. In a large study which looked at the dietary patterns of men diagnosed with localised prostate cancer, men with a Mediterranean dietary pattern had longer life expectancy. No association was found between a Mediterranean dietary pattern and progression of their prostate cancer to advanced or lethal prostate cancer [1].


Although Sparky came to Christian faith in a relatively conservative church, Lind outlines how his theological perspective broadened as he aged. Although Lind works carefully to note that Schulz was a Christian throughout almost his entire adult life, he also notes that he was unusually reticent about his faith, rarely speaking even to his children about his beliefs. When a friend suggested to him that he had evolved into a "secular humanist," Schulz wore the label in public from time to time, causing some observers to assume that Schulz was an atheist or an agnostic. Lind's purpose in writing this book seems to have been to refute this claim. Although Sparky was a sect unto himself, that sect was a branch of the Christian church. Schulz's reticence about his own faith and his clear personal preference for isolated insights over systematic thought makes a comprehensive account of his faith difficult to construct. Nevertheless, Lind succeeds in presenting a clear, enjoyable account of Sparky's religious ideas in which a resistance to over-theologizing, an impatience with formalism, and an allergy to overbearing religious institutions stand as key themes. Lind also notes that Sparky's methods of including religious themes in his strips and other media tended not to be prescriptive or "evangelical;" Schulz tended to frame biblical quotations and religious references in sparse narrative environments in which the reader must supply at least some of their own meaning. Without ever saying so, Lind seems to offer Schulz's approach to the tricky question of religion's place in media as a middle way between enforced secularism and blatant proselytization. As Lind admits, his volume is closely focused on Schulz's religious life and thought, and pays only passing attention to other aspects of his life. This focus is altogether appropriate, although there are parts of the story that could have been better contextualized. For instance, early in the book Schulz goes with amazing speed from being an unknown cartoonist to being a widely-known celebrity; this change makes Schulz a wealthy man rather quickly. Sparky was committed to philanthropic giving, but Lind does little to explore any connection that may have existed between Schulz's comfortable circumstances and his spiritual outlook. Lind's background is in communications, and he seems most comfortable in the field of media studies, the source of most of his historical context and theory. Although Lind's use of theory is light, it is suitable to the project, making meaningful interpretations of his subject possible. The University Press of Mississippi has published this book as a part of its commitment to publishing scholarly works on comics and comic artists, but students of this field should know that Lind makes little use of this literature. It is impossible to conclude without noting that Lind's primary research for this book was impressive and exhaustive. In addition to many interviews with people that knew Schulz well, Lind read every Peanuts strip, of which more than seventeen thousand are extant, and coded each one for religious content. This research, in and of itself, must have been a Herculean task. University Press of Mississippi has priced this book at a relatively low $25.00, expecting that it will be of interest to the general reader. They are right. A Charlie Brown Religion is appropriate for general readers with interest in the Peanuts franchise and its relationship to the Christian faith, pastors who may use Peanuts material in ministry from time to time, and scholars who have an interest in media and religion.


In this paper it is studied an open loop command method for controlling the position of a bidirectional moving magnet actuator with elastic magnetic forces (MMAEMF). This type of actuator has, due to its design, an equilibrium position that allows displacement of the actuator's rod in both directions. To energize and drive the actuator it is used a method of adjusting the duty-cycle of a PWM signal and MOSFET transistors. As a feedback non-contact displacement transducer it is used an arrangement of two linear ratiometric Hall sensors and a small permanent magnet disc attached to the mobile actuator's rod that moves between the two fixed sensors. Both input data, acquired from the sensors, and output PWM signal is processed through the pins of an open-source electronics prototyping platform based on Atmel microcontroller. Analog data acquired from the sensor is converted to distance after a calibration method through a lookup table. The setup allows measurements to be taken with 0.1 mm precision of the actuator's rod position and to plot the static characteristic of displacement for a range up to ±5mm.


Carboniferous is one of the most important reservoirs and producing formations,Carboniferous exploration is always the key and hot point in East Sichuan Basin even the whole Sichuan Basin. Based on research of the evolution of Kaijiang paleo-uplift,the characteristics and development controlling factors of reservoir and the preservation condition of gas pools,the controlling factors and accumulation mode of the Carboniferous gas reservoirs in east Sichuan Basin are studied,and it is held that the controlling factors of the Carboniferous gas reservoirs are: the evolution of Kaijiang paleo-uplift( which determines the accumulation of the gas reservoirs),highquality reservoir( which is the basis of forming the gas reservoirs) and cap rock condition( which is the key to forming the gas reservoirs). The accumulation of the gas reservoirs is divided into two stages. The first stage is the forming period of the paleo uplift and the paleo-gas reservoirs: Yunnan movement makes Carboniferous reservoir more developed,Kaijiang paleo-uplift is developed and basically formed in Indo movement,the Carboniferous is between two high-pressure mudstone layers,and a lot of hydrocarbon generated by the underlying Silurian source rocks forms a large scale formation-structural paleo gas reservoirs. In the second stage,the paleo gas reservoirs redistribute in traps due to Yanshanian movement and Himalayan movement.


Philodryas nattereri is distributed in arid and semiarid regions of South America and is most common in northeastern Brazil. The aims of the work were to investigate the edematogenic and myotoxic effects promoted by P. nattereri venom. In this work, mice weighing 20-30 g (n = 4 for each experimental group) were used. For the edematogenic activity mice were injected in the subplantar region of the right foot pad with 50 μL of solutions containing different amounts of venom (3 and 10 μg) measured by plethysmometry at 0.5, 1, 2, 3, 6, 12 and 24 hr and pretreated with indomethacin, dexamethasone and antibothropic serum, whereas the left foot pad was injected with 50 μL of NaCl 0.15 M. Two hours after injection mice were killed by cervical dislocation and both feet were cut off and weighed individually. For the myotoxic activity mice were injected i.m. with 100 mL of solutions containing 50 μg of venom. Blood samples were extracted after 2, 4, 8, 12, 24 and 48 hr of venom injection to determinate serum CK activity and mice were sacrificed at the same time intervals to obtain the inoculated gastrocnemius muscle. They were fixed with formalin solution and stained with Hematoxylin-Eosin. Results showed that P. nattereri venom exhibits a high edematogenic and myotoxic activities. Myonecrosis reached its highest level after 2 hr of venom injection as shown by plasmatic CK levels (364 ± 92 U/L) and microscopic assay. It demonstrates the potential toxicity of the venom of P. nattereri, who inhabits the North-East region of Brazil.


Abstract : TOLA is an acronym for TakeOff and Landing Analysis digital computer program. This part describes the use of the program. The basic program provides six rigid-body degrees of freedom of aerospace vehicle motion over a flat planet and determines the response of the aircraft to control inputs. The dynamics of up to five independent oleo-type struts are included for simulation of symmetrical and nonsymmetrical landings as well as drop tests. A maneuver logic is programmed to provide vehicle guidance in the various phases of the problem; it determines the desired trim and position in the glide slope and provides synthesis and attempted completion of necessary flare dynamics for prescribed touchdown velocity vector. The landing roll includes wheel spinup and braking, thrust reversing, spoiler deployment, and system failure options. The takeoff roll consists of acceleration to takeoff speed, followed by rotation to takeoff angle of attack.


Stellite 6 has been used as hardfacing material of valve components in nuclear power plant industry and other applications. Stellite 6 contains more than 60 wt % Co and it was recognized that Stellite 6 used in valve hardfacing is one of the main sources of Co, which is the major contributor to build up the radiation field in nuclear power plants. Thus it is largely responsible for the occupational radiation exposure of plant maintenance personnel. Also the price of Co is expensive and highly varying. Therefore, there have been many efforts to develop Co-free hardfacing alloy We have also developed Fe-based new alloy, of which sliding wear and cavitation erosion resistance were almost equivalent to those of Stellite 6. In the present study, the effects of Mn, Ti and V on the cavitation erosion behavior of the alloy were investigated. The Fe-based new alloy containing V had similar cavitation erosion resistance to Stellite 6 but the others containing Mn and Ti were inferior to Stellite 6.


Propp conjectured that the number of lozenge tilings of a semiregular hexagon of sides 2n?1, 2n?1, and 2nwhich contain the central unit rhombus is precisely one third of the total number of lozenge tilings. Motivated by this, we consider the more general situation of a semiregular hexagon of sidesa,a, andb. We prove explicit formulas for the number of lozenge tilings of these hexagons containing the central unit rhombus and obtain Propp's conjecture as a corollary of our results.


14 airican arts AUTUMN 2008 A s with many other ethnic groups in Africa, Sen ufo identity was the creation of the French colonial administration during the late nineteenth and early twentieth centuries. In spite of some similarities, those peoples whom the French grouped under the name "Senufo" do not share the same artistic and traditional forms and values. For example, while the Poro association and the art related to it are the core of the socioreli gious organization of the central and southern Senufo, northern Senufo groups do not have Poro or its associated arts. Northern Senufo groups are invested in the Komo men's society' and its associated objects, like those of their Mande-speaking neighbors. This is not surprising if we take into account that all of the Sen ufo country, from Koutiala to Katiola, was colonized by Mande speaking people well before the arrival of the French. Mande influences are still discernible in this larger region's architec ture and language. Tagwa, a Senufo people in Burkina Faso, do not have the same art traditions as central and southern Senufo groups. Although they were called Senufo by the French, Tagwa and all other Senufo subgroups still identify themselves by their specific languages, names, locations, and more importantly by their different socioreligious beliefs. Over the course of history, the arts of the Senufo have been exposed to various influences, which have all left their marks. Although Senufo groups differentiate themselves from others and are watchful of their own identity, they still are related to others. Yet despite external influences, a common societal foun dation for all these groups was created. For example, they share the same type of social and space organization, linguistic basis, architectural traditions, and music. However, it is not possible to determine a single cultural identity for the Senufo, and thus one cannot truly speak of a singular "art of the Senufo." Prior to this study, researchers never recognized the exis tence of Komo among Tagwa, although a number of scholars did study the Komo of the Minianka peoples in this zone.2 In Burkina, Nanergue, who border the Tagwa to the north, also possess Komo. Komo is the representation of the sacred art that allows Tagwa to define themselves as a Tagwa community and as a distinct ethnic group within the Senufo complex. The Komo society, which varies widely from village to village, is a testament to the independent nature of Tagwa communities. Each com munity determines the style of Komo so as to identify it with its


The holistic nursing service is based on the concept that humans are sick not only physically that cured by drug delivery, but also pay attention to other aspects of mental where the patient needs motivation and spirit to cope with illness, social where the patient wants to meet and gather with family/friends and spiritual where the patient wants to pray and pray for healing. Spiritual care is an important part of the overall care provided to improve the quality of life of patients. The role of nurses is now more involved on treatment measures. Proper methods in clinical supervision are necessary for the implementation of spiritual care to be as important as physical care, one of them using drill method. This study aims to analyze the infl uence of drill methods in the team leader's clinical supervision on the implementation of nurses spiritual care. The research method used is quasy experiment with pretest-posttest research design with control group design.

Aim. To study the clinical and anamnestic, and surgical features of patients with genitourinary system malformations.
Materials and methods. A retrospective analysis of data from 252 medical records of patients with genitourinary system malformations who were admitted for examination and treatment to the Department of Pediatric and Adolescent Gynecology of the Kulakov National Medical Research Center for Obstetrics, Gynecology and Perinatology of the Ministry of Health of the Russian Federation from 2012 to 2019. During analysis, special attention was paid to the data of surgical treatment, clinical and anamnestic data and the intraoperative picture.
Results. Developmental anomalies of the genital system are combined with urinary system malformations in 21.1% of cases. Genital malformations in adolescent girls are characterized by a high rate of various complications: hematocolpos (53.6), hematocervix (30%), hematometra (26.2%), hematosalpinx (15.1%), endometriosis (19.2%), masses (16.4%) and adhesions (25.4%).
Conclusion. Genital system malformations are often associated with anomalies of the urinary system and are characterized by a high risk of complications, therefore, timely identification and multidisciplinary management of such patients from an early age is extremely important.


Despite the toll of coronavirus disease 2019 (COVID-19) on health care workers, the United States lacks an effective way to track and evaluate COVID-19–related illness, deaths, and mental health effects in this group, warns a rapid expert consultation from the National Academies of Sciences, Engineering, and Medicine. In the 10-page document, a panel of experts identified deficiencies in current resources and methods for tracking and evaluating COVID-19–related deaths of workers in health care settings and suggested possible strategies to address these gaps. The report noted that such deaths include those resulting from direct occupational exposure to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and deaths that "reasonably" could be attributed to conditions exacerbated by COVID-19, such as suicides among health care workers fueled by fatigue, stress, or burnout. The panel noted that underreporting of risks to health care workers is especially likely during public health emergencies—a problem that is playing out in the COVID-19 pandemic—and described several factors that hinder tracking of COVID-19–related health care worker deaths. For example, on its COVID Data Tracker web page, the Centers for Disease Control and Prevention (CDC) reported 786 health care worker deaths attributable to infection with COVID-19 as of November 3, 2020. However, in compiling information about infections in this population, the CDC currently relies on coronavirus case report forms that typically are collected by local health departments. Queries about health care worker occupation type and job setting were not added to these forms until May 2020. Such data are still often missing. As a result of such omissions, only 22% (571 708) of 2 633 585 US COVID-19 cases reported to the CDC from mid-February to mid-July of 2020 had information about occupational status; among those cases, 100 481 patients (18%) were described as "health care personnel." Furthermore, states vary in their standards for reporting of occupational data; some lack any information about COVID-19 deaths by profession, and others report data on health care workers only in certain settings, such as hospitals but not nursing homes. Jurisdictions also vary considerably in completeness of reported data. Also lacking is a national system or reporting standards for measures of COVID-19–related morbidity, including effects on mental health, such as prevalence of burnout and suicide. The panel cited a March 2020 study of health care workers on the front lines of China's COVID-19 crisis that found significant numbers of workers coping with mental and psychological effects, including anxiety, depression, and insomnia. Similarly, a survey of 1557 health care personnel who worked during the 2003 SARS outbreak in Toronto found that one-third reported levels of posttraumatic stress symptoms comparable to those of survivors of a large-scale natural disaster. "The absence of a uniform national framework and inconsistent requirements across states for collecting, recording, and reporting [health care worker] mortality and morbidity data associated with COVID-19 impairs anyone's ability to make comparisons, do combined analyses, or draw conclusions about the scale of the problem," the report noted. The panel proposed steps that could be taken to address these gaps, including having an effective national data reporting system in place to collect data on where the infection occurred and factors such as circumstances and interventions that may boost or lower risk. This approach, the Author affiliations and article information are listed at the end of this article.

This conference aimed to raise the academic profile and visibility of Mexican mathematics within the international scientific community, and to strengthen the individual and institutional links among Mexican mathematicians and Mexican institutions.


Recently, Mobile Operators shift to 5G non-Standalone (NSA) network, through which fast 5G deployment is easily realized, and tend to share radio access network (RAN), so as to reduce capital as well as operational expenditure. In this paper, we choose the design of 5G NSA of single anchor, using the option of "LTE eNB as MORAN and NR gNB with MOCN" for RAN infrastructure sharing. In order to adapt the NSA network to our current network, and to ensure data transmission continuity, interoperation in multi-band networking is considered and realized by means of differentiated network selection, frequency priority configuration, and parameter configuration. A field trial is designed to verify the feasibility of the NSA network for RAN sharing, the results of which have shown: the interoperation in multi-band performs as expected, and apart from the high throughput, the NSA network has no negative impact on current LTE network, so it is suitable for the whole network construction.


Now the use of automatic machines is widely expanded. Each part of the machine plays an important role to ensure the ability of a machine and its works. In this project, the gripper is reviewed and analyzed to obtain the suitable force to grip the egg. Based on the identified problems, this project proposed to facilitate the work that used the gripper machine. Gripper part is important in a machine, whether in assembly process and pick and place process. A good design can produce a wellfunctioning machine and indirectly increasing the reliability of a product. This
project aims to facilitate the work in the industry and is focused on the gripper. This project is designed based on a number of constraints and the suitable factors used with the egg since the egg has an oval shape. Experiment is conducted by actual experiment on the Force Plate Machine. The results obtained are then compared and analyzed to get the best value force to grip the egg without crack or break.


Three different plasmid DNA extraction methods under the same conditions were adopted and compared to do the general survey endogenous plasmid DNA of six different lactic acid bacterial strains isolated from traditional fermented dairy products.Under the same conditions,the results of agarose gel electrophoresis showed that the improved Anderson-McKay method was the best,repeated freezing liquid nitrogen dissolved method was the second,and the improved alkaline lysis method was the worst.These tests provided effective methods for the extraction of endogenous plasmid DNA of Gram-positive lactic acid bacteria.


Three groups of subjects were tested in an elicited imitation study. These were 8-year-old, 11-year-old and adult native speakers of Arabic who were learning English as a second language. The subjects were asked to repeat sentences of seven different grammatical structure types. Previous research with 4-year-old native speakers of English (Smith, 1973) has found that three of the structures were easy to repeat (Type A structures) while four were difficult to repeat (Type B structures). In the present study, a similar difference in the repeatability of A and B structures was found for the youngest subjects, but there was no such difference for the adults and only a moderate difference for the intermediate group. The pattern of results suggested that this was not a function of differences in the subjects' English-language backgrounds, but represents a developmental difference in the ability of second language learners to repeat certain grammatical structures. The theoretical reasons for the variability in repetition difficulty for the different structure types were considered.
