This chapter focuses on the use of propaganda during times of war, prejudice, and political unrest. Part one distinguishes between persuasion and one of its forms, propaganda. The meaning-in-use of the term 'propaganda' is essential to understanding its use over time. Part two presents relevant examples of propaganda from the past several centuries in the United States and Europe. These examples include episodes from World War I and II, among others. Propaganda is not a new tool of persuasion, and learning about its use in the past provides a comparison that helps in understanding its use in the present and future. Part three looks at recent examples of how propaganda occurs in actual use in online terrorist mediums by Al-Qaeda and by the Islamic State in Iraq and Syria (ISIS).


Strengthening high entropy alloys (HEAs) via second phases is a very effective approach. However, the design of intermetallic (IM) phases in HEAs is challenging, mainly because our understanding of IM phases in HEAs is still very limited. Here, a statistical approach is used to enhance our understanding towards IM phases in HEAs. A database consisting of 142 IM-containing HEAs was constructed. Our aim is twofold. The first is to reveal the most common IM phase types in published HEAs. The second is to understand whether HEAs inherit their IM structures from their binary/ternary subsystems, or whether they tend to form new structures irrelevant to their subsystems. The results show that the five most prevalent IM structures in the HEAs surveyed here are Laves, σ, B2, L12, and L21. This trend is evidently different from the overall trend among known binary/ternary IMs. As for structural inheritance, all the IM phases contained in the alloys are existing structures in the binary/ternary subsystems of the respective alloys. This suggests that the compositional complexity in HEAs does trigger additional complexity in IM structure formation. These findings have important implications in the future design and development of HEAs.


Abstract The aim of this article is to present the collaboration between companies in the energy sector in Austria and Germany. During the financial crisis 2008–2012, Austrian energy companies became important partners of German firms supplying Germany with the energy necessary for industries and households. In addition, companies from Austria and Germany participated in the first phase of construction of the pipeline Nabucco. Thanks to manage capital of Austrian and German companies, they may now jointly pursue the objective of expansion in third countries market. After the energy reform, known as the Energiewende, Germany needs more electricity, which largely provide the company with a smaller, but equally high-tech Republic of Austria.


OBJECTIVE
Progressive myopia in humans and lid-sutured myopia in primates have been considered to be different processes. This report seeks to establish the connection between progressive myopia in humans and lid suture myopia in macaque monkeys.

METHODS
We followed the axial length of 4 lid-sutured macaque monkeys over an 18 month period. Their axial length is directly related to myopia. We also studied the myopia progression in corrected human subjects. Macaques and humans exhibit a linear time course of myopia progression when lid-sutured or corrected with lenses, respectively.

RESULTS
A linear progression is observed in lid-sutured eyes of four macaques, r = 0.94, p < 0.05. Human progressive myopia and lid-suture myopia can be modeled by the same feedback process. In both cases the functional equivalent is the opening of the feedback loop.

CONCLUSIONS
The open loop feedback process predicts a linear progression of myopia. This prediction was confirmed in human subjects and it is now confirmed in our macaque subjects. This process also explains the very rapid rate of myopia progression of lid sutured eyes.


Sandwich dimers are obtained by photochemical cleavage of dianthracene and related compounds in a rigid glass matrix at 77 K. Detailed studies of the absorption spectra, fluorescence spectra, and fluorescence lifetimes of symmetric dimers of anthracene and 9-substituted anthracenes (both molecules the same) and dissimilar dimers (one molecule anthracene, the other 9- or 9,10-substituted anthracene) have been made. Particular attention has been paid to these properties during dissociation of the dimers as the glass is allowed to soften. The fluorescence properties show a discontinuity during this dissociation. The excimer emission maxima (lifetimes about 200 ns) move a little to higher energy (lifetimes decrease to about 100 ns) then broad structure is observed in the spectra and lifetimes drop to about 5 ns. The fluorescence spectra of the dissimilar dimers are of the excimer type with lifetimes of about 100 ns. These values do not appear to be compatible with existing theories of the excimer state.

ABSTRACT Time-related information in land-change studies is reviewed using case studies in JLUS and LAND. An explicit focus on time has potential for exploring process-based perspectives. We report how time is represented and patterns in pre-analytical choices are detected, identifying practices to enhance the relevance and impact of land-change studies. Results show 40% of the studies use two datasets; the modal timespan and interval between datasets are 10 years; 79% are durations up to 30 years; 73% are changes since 1972. Modal start dates are 1990 and 2000. Dates ending in 0 and 5 are over-represented and lack explicit justification. The prevalence of a 'two-date approach' restricts measuring and analyzing change, identifying temporal non-stationarity is precluded, and modelling change pathways and responses to underlying system dynamics are limited. An improved focus on time in dataset choice to developimproved understanding of dynamics and change offers broader insights into land-system functions.


Abstract Introduction The coronavirus outbreak has had significant impact on medical students worldwide. SMILE is a free online access medical education (FOAMed) platform. SMILE delivered 200 lectures during lockdown with up to 1400 students per session from both UK medical schools and 33 abroad. Here we discuss student perceptions to SMILE during lockdown Method An electronic survey was used to collect information from students who had utilised the platform during lockdown. This examined access to learning, impact on their mental health during lockdown and the differences between FOAMed and more traditional based campus lecture based learning. Results 1306 students responded to the anonymous survey with 94% of students stating SMILE had been "extremely useful" or "very useful" at supplementing learning during covid. 71% of students stated lockdown had affected their stress levels and 44% reported deterioration in their mental health. >80% felt SMILE improved stress levels by adding structure and providing motivation. Students attended 4.3hours/week of university teaching, vs 7.9hours/week by SMILE. Positives included: anonymity, making 80% more likely to both ask and answer questions, the informal approach, ease of access and enthusiastic teachers. Negatives included time differences and technical issues such as poor Internet. 98% stated they would be interested in future SMILE projects post lockdown Conclusions SMILE addressed challenges identified during an unanticipated transition towards the online provision of medical education on an international scale. Students found SMILE lectures effective, accessible and safe, supporting FOAMed as part of the "new normal" post lockdown


To promote coupling coordination development for regional innovation environment-resource-output-benefit (EROB) composite systems, we propose a data-driven integrated model method for measurement, evaluation, and identification. First, we construct an evaluation indicator system of coupling coordination development of regional innovation EROB composite systems. Second, we apply the entropy method to measure indicator weights and comprehensive development indices of regional innovation composite systems. The coupling coordination degree model is used to calculate and evaluate four subsystems' coupling coordination development levels. The obstacle degree model is used to identify the main obstacle factors affecting coupling coordination development. Finally, using panel data of the Yangtze River Delta region (three provinces and one city) between 2014–2019 as a case study, we test the integrated model method. The results show that the comprehensive development level of the regional innovation EROB composite system in the Yangtze River Delta region maintained a stable growth trend; the coupling coordination development level among four subsystems continuously improved, with the main obstacle being the innovation resource subsystem. Accordingly, targeted policy suggestions are put forward. This study not only provides theoretical and methodological support for evaluating and optimizing regional innovation composite systems but also provides decision-making support for sustainable and high-quality development of regional economies.


The article attempts to juxtapose myths and the realities of Zimbabwe and prove that the viewpoints wide-spread in the international media and even academic community are far removed of those realities. Against the historical background it analyses the economic and political crisis the country faced in the beginning of the 21st century and the period of the "all inclusive government". Special attention is paid to the 2013 presidential and parliamentary election and to the reasons of Robert Mugabe's victory.

Aims: Paddy field is one of the sources of greenhouse gasses such as methane (CH4) and nitrous oxide (N2O), which causes global warming and other negative effects in agricultural sector. An alternative to optimize paddy productivity and reduce emissions of CH4 and N2O is by using methanotrophic bacteria and Ochrobactrum anthropi BL2. Methodology and results: This study consisted of two parts, i.e. positive control and experimental treatments. Positive control consisted of 250 kg/ha NPK inorganic fertilizer NPK (15:15:15) (100% of the recommended normal dose) without any methanotrophic bacteria. Meanwhile the experimental treatment consisted of 50 kg/ha inorganic fertilizers NPK (20% of the recommended normal dose) with methanotrophic bacteria (Methylocystis rosea BGM 1, M. parvus BGM 3, Methylococcus capculatus BGM 9, Methylobacter sp. SKM 14) and N2O reducing bacteria (Ochrobactrum anthropi BL2). Using weight indicator of 1000 grams, all the bacteria are capable of increasing paddy productivity by 42.07%, compared to conventional method which can only increase the productivity by 2.51% (Cepy and Wangiyana, 2011). The increasing productivity and growth of paddy plants were due to the nitrogen fixation activity of M. rosea BGM 1, M. capculatus BGM 9, and Methylobacter sp. SKM 14. In the experimental treatment using bacteria, the emission of CH4 and N2O was reduced with the highest CH4 and N2O sinks of 24018.8 mol CH4/day/ha and 68.48 mol N2O/day/ha, respectively. However, the positive control treatment with 100% of the recommended fertilizer dose showed the highest CH4 and N2O emissions which were up to 74346.45 mol CH4/day/ha and 26.21 mol N2O/day/ha, respectively. Conclusion, significance and impact study: All the methanotropic bacteria and O. anthropi BL2 are significantly increase paddy production, compared to positive control treatment. The addition of bacteria in paddy fields results in CH4 and N2O sinks.


Treatments to control browning and maintain quality of freshcut pears were evaluated. Pear wedges were dipped in solutions containing sodium erythorbate, CaCl 2 and 4-hexylresorcinol; packed in air or with a modified atmosphere (MAP); and stored at 4°C. Samples were evaluated for browning, microbial spoilage, and presence of off-flavors or loss of firmness. For treatments to be successful, pears had to be above a minimum firmness of 4 kg (d'Anjou) or 5 kg (Bartlett) when treated. inhibitor treatments, in conjunction with MAP, controlled browning and maintained quality of fresh-cut Bartlett and d'Anjou (but not Bosc pears) for 12-14 days.


The Fermilab Mu2e experiment seeks to measure the rare process of direct muon to electron conversion in the field of a nucleus. The magnet system for this experiment is made of three warm-bore solenoids: the Production Solenoid (PS), the Transport Solenoid (TS), and the Detector Solenoid (DS). The TS is an "S-shaped" solenoid set between the other bigger solenoids. The Transport Solenoid has a warm-bore aperture of 0.5 m and field between 2.5 and 2.0 T. The PS and DS have, respectively warm-bore aperture of 1.5 m and 1.9 m, and peak field of 4.6 T and 2 T. In order to meet the field specifications, the TS starts inside the PS and ends inside the DS. The strong coupling with the adjacent solenoids poses several challenges to the design and operation of the Transport Solenoid. The coil layout has to compensate for the fringe field of the adjacent solenoids. The quench protection system should handle all possible quench and failure scenarios in all three solenoids. The support system has to be able to withstand very different forces depending on the powering status of the adjacent solenoids. In this paper, the conceptual design of the Transport Solenoid is presented and discussed focusing on these coupling issues and the proposed solutions.


This research aims to investigate the suitable measurement method of human capital quality and its indicators including both extrinsic and intrinsic factors. Research data were collected randomly from more than 400 students per chosen university in different academic years at the current five most famous economic universities in Vietnam, with 1796 observations and 2100 questionnaires. By combining the use of qualitative and quantitative methods with the support of EVIEW 10 and STATA 22 software, the study was conducted evaluate the impact of four extrinsic factors (academic staffs, administration services, curriculum structure, and infrastructure) and seven intrinsic factors that reflect students' motivation (learning purpose, acquiring knowledge ability, learning method, hardworking, self-awareness, and relationship development) on human capital quality (expressed through knowledge, skills, and attitudes). The research results indicate that students' motivation is the most important factor promoting human capital quality whereas administration services and infrastructure has a negative impact on human capital quality. Furthermore, while academic staffs only influence slightly and positively on students' attitudes curriculum structure can impact both students' skills and attitudes.

Naphtheledicarboxylato ((NDC2–) bridged coordination polymers (CPs) along with (E)-1-methyl-2-(p-chlorophenylazo)imidazole (ClPai-Me) coordination to Co(II), [Co(∝-NDC)0.5(∝4-NDC)0.5(ClPai-Me)]·0.5H2O (1), and to Zn(II), [Zn(∝-NDC)0.5(∝4-NDC)0.5(ClPai-Me)]·0.5H2O (2), have been characterized. In the single crystal X-ray structure of 1, ClPai-Me chelates to the Co(II) ion by N(azo) and N(imidazolyl), whereas in compound 2, it acts as a monodentate N(imidazolyl) donor to the Zn(II) ion. The coordination atmosphere around Co(II) in the 1 ion is distorted octahedral CoN2O4, whereas in the case of 2, it is distorted square pyramidal ZnNO4. Compounds 1 and 2 exhibit the right-handed (P) and left-handed (M) one-dimensional helical chain. NDC–2 is serving as a bridge between two M(II) ions to constitute μ-NDC and four M(II) ions to construct μ4-NDC to assemble three-dimensional polymers. Upon UV light (369 nm) irradiation, compound 2 shows trans-to-cis isomerization of -N═N–C6H4–Cl-p both in the solid and solutio...


Potassium (K) aflects a range of physiological processes in the plant and is a key factor controlling crop productivity and yield quality. Little information is available concerning effects of K nutrition on function of cut flower plants. The present study was carried out to investigate the interaction between K and N nutrition, on flower quantity and quality of Ranunculus asiaticus L. The plants were supplied with three levels of K fertigation (60, 120, or 180 mg K L-1) under 50 mg N L-1 application, and at the intermediate level of 120 mg K L-1, to three levels of N applications (50, 100, or 150 mg N L-1). The two lowest K treatments and the lowest N treatment excelled in flower production due to the lower incidence of stem-toppling, a disorder associated with localized Ca deficiencies in rapidly expanding tissues of the flower stem. Detrimental effects in terms of yield quality were apparent already under supply of 180 mg K L-1 and 50 mg N L?1, and were not associated with changes in osmotic potential, relative water content or membrane stability of the plant tissue, or with changes in mineral contents of the leaves other than reduced Ca under high N application. Our results suggest a low nutritional requirement of R. asiaticus L. for K and N, a lack of involvement of tissue water relations in the reduced flower quality under the application of high concentrations of K and N, and an induction of stem toppling under high application of N and K by reduced availability of Ca to the expanding tissue of the flower stem.


Prepaid personal communication service users have outnumbered postpaid users. This paper studies the charging issues of an integrated Global System for Mobile Communications (GSM) and General Packet Radio Service (GPRS) prepaid service, where a single prepaid account provides a user both voice and data services. The call setup and charging procedures for GSM and GPRS are presented using the Customized Applications for Mobile network Enhanced Logic network architecture. To reduce the probability of terminating both ongoing voice and data calls, we suggest that no new call be admitted when the user credit is below a threshold. An analytic model has been developed to evaluate the performance of the approach. Computer simulations have also been used to verify the results. The numeric results indicate that the force-termination probability can be significantly reduced by choosing an appropriate threshold of the user credit


By using a modified PFC2D model, the authors conducted a series of simulations to examine the influences of in-situ stress ratio, fluid injection rate, anisotropy of laminated rocks, and perforation parameters on hydraulic fracturing process. The simulations indicated that: 1) larger in-situ stress ratio will induce smaller breakdown pressures and faster propagation, and hydraulic fractures will extend along the direction of the maximum principal stress or approach to this preferred path; 2) smaller difference of in-situ stresses or faster fluid injection rate is helpful for creation of complex fracture network; 3) weak layers are preferred locations and directions for fracture initiation and propagation in the laminated rocks; 4) hydraulic fractures initiate easily at the bottoms of perforation channels, and propagate generally along or approaching to the direction of maximum principal stress.

The Canadian Corporation for the 1967 World Exhibition recognised by December 1963 that a major transportation system was required to move visitors through the exhibition area, of 1,000 acres spread out over about three miles, up to 350,000 visitors being expected on peak days. Transportation consultants were charged with planning a system to join the central business district of Montreal to the four main locations of the exhibition.


Although it may be tempting to say that almost any rewarding activity can become addicting, new research appears to indicate that, at least in the case of Internet use, that may not be the case. In fact, "Internet addiction" may actually be a sign for other psychiatric disorders.


Rare and highly aggressive adult soft tissue sarcomas, leiomyosarcoma (LMS) and undifferentiated pleomorphic sarcoma (UPS), contain complex genomics characterized by a multitude of rearrangements, amplifications and deletions. Since differential diagnosis between the two sarcoma histotypes continues to remain a challenge, we attempted to identify a specific signature useful for improving the differential diagnosis, and we performed miRNA profiling on series of LMS and UPS samples stored at Rizzoli biobank. First, we investigated the different miRNA expression profile in 20 primary sarcoma samples, 10 high-grade LMS and 10 UPS, MFH-like, using miRNA array technique. The top 5 differentially expressed (p Citation Format: Laura Pazzaglia, Mohamed Guled, Ioana Borze, Maria Serena Benassi, Piero Picci, Sakari Knuutila.

Abstract Numerous marine fishes from the Algerian coast were examined for nematode parasites. Our study revealed five species of nematodes that were identified according to morphological characteristics: Anisakis simplex, Hysterothylacium aduncum, Hysterothylacium reliquens, Hysterothylacium fabri, Dichelyne pleuronectidis. D. pleuronectidis was newly collected from the study region. Four new host species were recorded for A. simplex, six for H. aduncum, and three for H. fabri. The infection rates observed were higher for Hysterothylacium and Dichelyne than Anisakis. The highest infection rate by Nematoda parasites were recorded for Trachinus draco L., Pagellus acarne (Risso) and Mullus barbatus L. (P = 100%, P = 53.33%, P = 42.5%), respectively. Nematoda larvae were found in body cavity and musculature. Histological changes associated with nematode musculature infestation revealed myodegeneration of fibers with a loss of striated texture and skin damage.


This research discusses and analyzes the company's profitability related to the company's stock return performance Profitability of the firm is related to the firm's performance of stock return. This study uses time-series data with a total sample of 1,010 firms from five countries in ASEAN (Indonesia, Thailand, Malaysia, Philippines, and Vietnam) from January 2010 to December 2019. Fama-French 3 factor model based on two different profitability showed that profitability positively affects the stock return in ASEAN markets. Fama-MacBeth's (1973) regression confirms that firm profitability scaled by operating profit-to-equity or operating profit-to-assets positively influences expected stock returns in the ASEAN market.DOI: 10.26905/jkdp.v25i3.5598


Children learn quickly from their own parents and as they grow up computers offer more learning options. However they would learn better if the lessons are properly constructed using cognitive, constructivist, collaborative and technical education principles i.e., incorporating mathematics lessons on the computers. This paper reports an 'experience' gained by a veteran mathematics teacher in building a courseware called CDiCL using ADDIE principles. The quasi-experimental research was run in Polytechnic Kota Bharu PKB, Kelantan under Ministry of Higher Education (MoHE) Malaysia among 137 students at Certificate Engineering students in March 2006 among 4 different groups within 8 weeks. It was discovered CD only group scored the highest gain score of 6 points (difference in Post Test and Pre Test) while CL (Collaborative Learning) only group scored the least 2 points. From clinical interview, many students failed to understand mathematics from the courseware because of English and behavior problems among participants but some leaders in CL group gained leadership experience demanding soft skills in understanding peers' limited skills and anxiety at presenting mathematics problem solving. The study concluded with a framework / rubrics for teachers to be effective dealing with mixed ability group of students learning mathematics on computers.


The possibility of using two models of geometry in the analysis of bridges consisting of a tubular frame combined with a concrete slab is presented. The first model is derived from the orthotropic plate theory and the second one is a discrete model including beam elements (the structure) and shell elements (the slab). This makes it possible to adopt some easy to model flat two-dimensional elements. Also, the use of the Guyon–Massonnet distribution method is possible, if preliminary dimensions of structural elements are chosen. The concept of evaluation of torsional stiffness for equivalent orthotropic plate is developed. The algorithms for determining the influence of the surface of internal forces and normal stresses in structural members in the case of discrete model are given, which is necessary for a detailed static analysis. The algorithm based on kinematic method is essential for the use of standard FEM software. The practical use of the algorithms proposed is shown by numerical examples.


This study aims to contribute to improving mental health services and establishing a direction for disaster survivors by verifying the effectiveness of the TLS (Training for Life Skills) app, a mental health management mobile application. Altogether, 22 disaster survivors received access to the app (with guidance) for eight weeks; we analyzed its effectiveness by examining each participant's electroencephalography data, which were collected while they were utilizing the app. The results of this study show that the use of the TLS app had a significant positive effect on emotional quotient, basic rhythm quotient (left brain, right brain), alpha blocking rate (left brain, right brain), and brain quotient of disaster survivors. The TLS mobile app is expected to not only provide psychological first aid to disaster survivors but also to improve their life skills, which may allow them to gain information about their emotions; hence, it may provide the appropriate conditions needed to enable effective self-control and health management for disaster survivors.


The distortion technique has been applied to validate quantitatively a dynamic model of a scatter plug as used on advanced gas-cooled reactors from comparison with recorded rig results, A brief outline of the technique is given which illustrates the distortion required for the constant parameters within the model and the assessment of model adequacy. Initially these assessments indicated that the model was not adequate to explain the test results. This led to significant improvements of the model and better under. standing of the model and the tests, Eventually, after several improvements in the model, the quantified criterion inherent in the distortion technique was satisfied indicating model adequacy.

This article examines the Labour Party's experience of the general election of 1945. Using a variety of unpublished and published sources, it reviews the party's strategy, policy, and organisation at the end of the Second World War. It also considers the relationship between the election victory and the state of wartime public opinion. In 1945 there occurred the conjuncture of a number of factors rare in Labour's history: a cautiously sympathetic public, a tired Conservative Party, and, not least, a moment of coherence and unity within the party itself. What this article stresses is the particular coincidence of such elements in 1945, all of which contributed to the Labour victory.

Student, Dept. of Dual Degree Computer Applications, Sree Narayana Guru Institute of Science and Technology N.Paravur, Kerala, India ---------------------------------------------------------------------***---------------------------------------------------------------------Abstract We propose a deep convolutional neural network for 3D human pose and camera estimation from monocular images and live camera that learns from 2D joint annotations. And this Paper proposes to build a multi-source deep model in order to extract non-linear representation from these different aspects of information sources. The collected images cover a wider variety of human activities than previous datasets including various recreational, occupational and house holding activities, and capture people from a wider range of viewpoints. Using Video cameras we will capture the live situation from the world space and using this technology it will give estimated data to the screen and we will collect these data at every frames per second, Using Data direct to Game development. This technology will shows how to use the real Human specific pose data to game development at the time of Game 3D-Modelling. For example, a very popular Deep Learning app "HomeCourt" uses Pose Estimation to analyses Basketball player movements. To implement this motion capture for animation in game development and videos, we would require specialized hardwares.Xsens is a company it will able capture the pose motions in the cameras.


We study suprathermal electron distributions (E > 80 eV) in regions adjacent to interplanetary (IP) shocks driven by interplanetary coronal mass ejections (ICMEs). The shocks were observed by the two STEREO spacecraft during the years 2007-2010, hence during the minimum and at the beginning of the rising phase of the current solar cycle. All the ICMEs were isolated events, meaning that the shocks were produced only due to interactions of the ICMEs with the solar wind. We find that suprathermal electron pitch angle distributions (PADs) in regions adjacent to ICME driven IP shocks vary from shock to shock. At some shocks, these electrons show the "usual" isotropic halo and a narrow, field-aligned strahl. The PADs upstream and downstream of these shocks differ only in the width of the strahl, with the later being wider in the downstream regions. In other cases we observe unusual downstream conical distributions at intermediate angles (between 0 and 90 or 90 and 180° PA), counterstreaming electrons at the shock transitions and downstream PADs without the strahl component. Here we present two shocks from our sample with such unusual electrons distributions, not reported in the literature.We study suprathermal electron distributions (E > 80 eV) in regions adjacent to interplanetary (IP) shocks driven by interplanetary coronal mass ejections (ICMEs).

High resolution X-ray computed tomography (HRXCT) has been barely used in speleothem science. This technique has been used to study a Holocene stalagmite from Praileaitz Cave (Northern Spain) to evaluate its potential for petrologic studies. Results were compared with those derived from the routine procedures and a very good correlation was found. Our work indicates that HRXCT can be considered as a useful tool for a rapid and non-destructive characterization of the speleothem, providing important information about petrological textures, spatial distribution of porosity, and diagenetic alteration, as well as stratigraphic architecture. These encouraging results indicate that HRXCT can offer interesting perspectives in speleothem science that are worth future exploration.


China's mine water comprehensive utilization rate is low. The main reason for the increase in the utilization rate after 2015 is the reduction in coal production. The shutdown of a large number of coal mines by capacity has objectively led to a reduction in mine water volume. Based on the development and utilization of mine water, this paper clarifies the characteristics of mine water utilization mode, and discusses the classification of mine water utilization mode and suggestions for safeguard measures in terms of mine water utilization targets and treatment difficult. The research undertook in this paper will expand the utilization of mine water and improve the utilization rate of mine water. It will help enterprises realize the transformation of mine water into waste and realize the value-added effect of mine water. It is desirable for the unconventional water resources will be integrated into the water source. It can help ease the contradiction between water supply and demand in water shortage areas and improve the efficiency and utilization efficiency of regional water resources allocation.


The magnetic dynamics of low-dimensional iron ion chains have been studied with regards to the tunable finite-sized chain length using iron phthalocyanine thin films. The deposition temperature varies the diffusion length during thin film growth by limiting the average crystal size in the range from 40 to 110 nm. Using a method common for single chain magnets, the magnetic relaxation time for each chain length is determined from temporal remanence data and fit to a stretched exponential form in the temperature range below 5 K, the onset for magnetic hysteresis. A temperature-independent master curve is generated by scaling the remanence by its relaxation time to fit the energy barrier for spin reversal, and the single spin relaxation time. The energy barrier of 95 K is found to be independent of the chain length. In contrast, the single spin relaxation time increases with longer chains from under 1 ps to 800 ps. We show that thin films provide the nano-architecture to control magnetic relaxation and a testbed to study finite-size effects in low-dimensional magnetic systems.


In this paper, a previously developed modification of the Sainz model of multiaxial fatigue is reduced to an invariant form. Model constants were determined for different sets of setup experiments. It was supposed to introduce an additional summand to account for the phase shift between loading modes. The model is used to describe the fatigue behavior of the D16T aluminum alloy. Low-cycle fatigue tests under biaxial loading conditions are presented, with one mode changing cyclically and the other mode remaining constant in magnitude throughout the test. The results of cyclic durability prediction by the modified model provide good convergence.


The author analyzed and compared the characteristics and reasons of domestic tourists consumption structure in Anhui in 2001.It concluded that the main domestic tourist's consuming items were rigidity ones.Flexibility ones had low proportions.Tourists generally preferred living and eating consumptions,shopping and entertaining was the weakest items.In order to achieving the rationalization of consumption structure,advancing consumption level,accelerating the escalation of tourism industrial structure and keeping the standing grow of tourism economic benefits,Anhui Province should establish many kinds of entertaining facilities,enriched recreational functions of beauty spots,elevated the rank and distribution ability of tourism commodities,and constructed walking streets which offered not only shopping services,but also eating and amusing ones.All-points safety consumption circumstances were also required.


There are in the literature a number of conflicting statements regarding the effect of various stimuli on the cypris stage of barnacle larvae, before and at the time of metamorphosis, and little experimental work has been done to elucidate the type of reactions involved. Visscher (1928), working with Balanus amphitrite, B. improvisus and Chthamalus fragilis, stated that during the earlier part of their free-swimming stage the cypris larvae were positively phototropic, but later the reaction to light became erratic, and at the time of attachment was decidedly negatively phototropic. He further stated that in a settlement experiment they orientated with the anterior end (i.e. with the paired eyes) away from the light source. However, MacDougall (I943) working with two of the above species (Balanus improvisus and Chthamalus fragilis) and also Balanus eburneus, and Pyefinch (I948) working with B. balanoides and B. crenatus, both state that the cypris larvae retain their positive reaction to light up to the time of settlement. There also appears to be some disagreement regarding the orientation at, and subsequent to, metamorphosis of several species of barnacles. Moore (1935), in considering B. balanoides, has suggested that if a barnacle is settling in a current, then at the time of settlement it is likely to be orientated with the current. A general orientation at right angles to the current was supposed to be due to rotation after settlement. This rotation was considered to be a response to the orientation of the beating cirri in relation to the current; it was suggested that feeding would be more effective with the animal orientated across the current.


The present invention relates to a startup control method of an electric motor (1) brushless three-phase synchronous comprising a step of aligning the direction and the direction of the magnetic polarization of the rotor (5) with a position of alignment (PA) defined by the direction and sense of the polarization of the stator (2) determined based on the information read from the position sensor for the direction of the magnetic polarization of the rotor, said alignment step being performed for a period after which the oscillation amplitude and / or speed of the rotor (5) is less than a predetermined threshold.


Simultaneous Localization and Mapping (SLAM) is a popular topic in autonomous robots navigation. It has been studied for decades in both computer vision and robotics communities. Monocular systems is more cost effective compared to RGBD or Stereo systems; however, it is relatively complicated to initialize due to scale uncertainty. Under certain conditions, it is assumed that the camera only moves in a planar scene, which provides us with homography constraints. In this paper, the efficiency of monocular initialization was improved based on the open source platform ORB-SLAM2, employing the algorithm based on planar homography constraints. We compared the improved algorithm with the source code of ORB-SLAM2 on the public datasets. It showed that our algorithm has better stability and robustness in the planar scene dataset and more initializing map points.


The present issue (vol.82, no.2, 1994) is the third in the Proceedings of the IEEE to be devoted to radio and radar astronomy. The first appeared in January 1958, a significant date because it was 25 years after Karl G. Jansky's first report of his discovery of Galactic radio noise. The second was 15 years later in September 1973, and was devoted to reporting how the science had progressed. The 15-year timespan had marked a period of rapid advance that had yielded a wealth of discoveries. Now, 21 years later, the field is still dynamic and continues to produce an abundance of findings, due in part to the large number of new observatories. In the present issue, the focus is on the design and performance of the antennas and the instrumentation used in radio astronomy. The issue concentrates on already existing and operational telescopes. Perhaps yet a future issue is merited, one devoted to those new telescopes that are still on the drawing boards. >


Objective To observe the clinical efficacy of lumbar plexus block in elderly patients undergoing total hip arthroplasty.Methods Sixty ASA Ⅰ-Ⅱ patients scheduled for elective total hip arthroplasty under general anesthesia with tracheal intubation were randomly divided into two groups,with 30 patients in each group.The patients in group L received lumbar plexus block guided by nerve stimulator with 30 mL of 0.5%ropivacaine before anesthesia induction.The patients in group C received no treatment.Patients were given patient-controlled intravenous analgesia(PCIA)with sufentanil after surgery.The VAS score was maintained at less than or equal to3.If VAS score was greater than 3,patients were given intravenous injection of ketorolac tromethamine.The heart rate(HR),mean arterial pressure(MAP)and oxygen saturation(SpO2)were recorded after admission to operating room(T0),immediately after the beginning of surgery(T1),10 minutes after the beginning of surgery(T2),30 minutes after the beginning of surgery(T3),and at the end of surgery(T4).The Bruggman comfort score(BCS)was recorded 2,4,8,12,24 and 48hours after operation.The consumption of sufentanil within 24 hours after operation,usage of ketorolac tromethamine and postoperative adverse reactions were observed in all patients.Results Compared with T0,MAP and HR significantly increased at T1-T4 in group C(P0.05).No significant differences were found among different time points in group L(P0.05).Compared with group C,MAP and HR decreased,BCS increased and sufentanil consumption and ketorolac tromethamine usage reduced in group L after operation(P0.05).There were no significant differences in the SpO2 and postoperative adverse reactions between group C and group L(P0.05).Conclusion Lumbar plexus block combined with general anesthesia can stabilize the hemodynamics,improve the postoperative analgesia and reduce the dosage of opioid analgesics in elderly patients undergoing total hip arthroplasty.

The forward anti-collision early-warning method based on the laser radar has the following beneficial effects: car owners are early warned or measures are taken out for the cars according to different early-warning grades, thus the anti-collision effects are achieved, rear-end collisions are effectively reduced, and traffic accidents are reduced.


Objective To develop a straight wire bracket placement gauge with a markable design. Methods The gauge was consisted of three parts: a marking plate with inclination slopes for each tooth in the middle, two cross rods and a height ruler. The cross rods can be connected with paint markers under their lower portion. The height ruler with position marks can indicate the distance from the incisal or occlusal edges to the bracket center. When applied, the angles of the cross rods can be adjusted according to the tooth tip and the vertical rod need to be in agreement with the facial axis of the clinical crown. When the gauge was centered by the height ruler, the gauge should be pushed to the surface of tooth thus to produce position marking. Results This gauge can mark out the accurate bracket position and the tooth crown inclination. Conclusion The newly designed markable straight wire bracket placement gauge may greatly improve the accuracy of the bracket placement.


The external tank (ET) of the space transportation system (STS) contains liquid oxygen and liquid hydrogen as oxidizer and fuel for the space shuttle main engines. This article describes a two-dimensional flow and thermal forced convection analysis to determine solar heat effects on the space shuttle launch components subsequent to the ET loading operation in extremely hot conditions. An existing computational fluid dynamics (CFD) code, parabolic hyperbolic or elliptical numerical integration code series (PHOENICS `81), was used in the study. The analysis was done for a two-dimensional slice between planes perpendicular to the longitudinal axis of the STS and passing through the lower portions of the redesigned solid rocket motors (RSRMs), the ET, and the orbiter wing. The results are presented as local and average values of surface temperatures and Nusselt numbers around the RSRMs and the ET. Solar heating effects increased surface temperatures of the RSRMs by 5-6.1 C. Comparisons were based on the local Nusselt number at the forward stagnation point and on the average Nusselt number around the West RSRM. 36 refs.


As many of yours surely have, my institution, the University of Illinois-Chicago (UIC), moved at great speed to adapt to the need for online instruction this fall. This has proved a challenge for library instruction, to put it mildly. Our library instruction has almost exclusively been in-person, on-site, and live, and the switch to online and hybrid course delivery has made all of those aspects difficult, especially when it comes to courses offered asynchronously, where students engage with course content at different points in time within a given timeframe.


Unobtrusive pressure sensors can be used for biological monitoring and long-term health assessment in smart homes. The challenge in detecting events from smart home data is that people have different mattresses, unlike in hospitals where bedding is standardized. This paper proposes to model central apneas using an under-mattress pressure sensor as a measuring instrument. The model uses three parameters, namely, a relative threshold and two time lengths, applied to a moving variance signal. The use of a relative threshold allows apneas to be detected under a variety of different conditions and improves results compared to hard-coded thresholds. The algorithm developed herein was applied to simulated apneas collected from pressure sensors placed under nine different mattresses. The parameters determined from the training set were applied to the test set and produced classification results of 0.78 positive predictive value (PPV) if the bed occupant's position is known and 0.75 PPV if the position is unknown. The use of the relative threshold approach overcomes the variability in mattress types found in smart homes.


We report the fabrication of submicron GaAs/AlAs double-barrier resonant tunneling diodes (RTDs) using wet etching with In droplets as a mask. Uniform mesas about 400 nm in size were formed and showed a clear resonance feature in current–voltage (I–V) characteristics, indicating that the mesa worked as a RTD. This simple technique can be applied to the fabrication of various submicron diodes.


The Santa Gertrudes ceramic manufacturing pole, located in the state of Sao Paulo, south-eastern Brazil, produces around 20 million m 2 of tiles per month (∼240 million m 2 /year) at 42 manufacturing units. The main characteristics of the tiles produced here are the body's reddish colour, glazed surface, water absorption between 6 and 10 % (Bllb type), and their floor and wall applications, particularly indoor applications. The manufacturing route consists of dry powder preparation, dry pressing, and rapid and single firing. In addition, one particular characteristic of the ceramics produced in the Santa Gertrudes pole is the unique and single raw material (clay) used in the body's composition. This material comes from clayey rocks in the Parana basin, a huge Phanerozoic intracratonic sedimentary basin covering 1,100,000 km 2 in southern Brazil, and 100,000 km 2 each in Uruguay, Paraguay and Argentina. In the region of the Santa Gertrudes pole, clayey rocks used as raw material in the manufacture of ceramic tile bodies are grouped in the Permian Corumbatai Formation (Pc). This is a 130-m-thick layer of shallow reddish marine sediment containing claystone, shale, siltstone and fine sandstone embedded in dark bituminous shale, with carbonate rocks at the bottom (Irati Formation) and topped by fluvial-Aeolian sandstone units (Piramboia and Botucatu Formation(, which forms a coarsening upward sequence characterising a regressive sedimentary cycle. The main minerals in these clayey rocks are illite, with minor amounts of smectite and kaolinite, and quartz, feldspar, hematite and iron hydroxides. The sandy facies are rich in feldspar, whose granulometric size is less than 120 μm. Biogenic fragments (bone beds and coquina) are present in centimetre layers. The main oxides present here and their approximate chemical composition are: SiO 2 (67 %), Al 2 O 3 (15 %), Fe 2 O 3 (5 %), K 2 O (3-4 %), Na 2 O (0.5 %) and CaO (0.5 %). Despite a preference for the bottom and intermediary stratigraphic portions of the Corumbatai Formation, mining activities take place throughout the unit, from top to bottom, except where clayey rocks display severe weathering, silica and/or carbonate veins, biogenic concentrations, basaltic intrusions and intercalations of sandy facies. Mining is conducted by traditional open pit methods, involving the usual stages of clearing the vegetation and stripping, followed by blasting or hydraulic scraping (depending on rock strength) using single or multi benches. The ore, in the form of rocks and pebbles, is then loaded onto trucks and transported as run-off-mine to outdoor aging stockpiles or to a primary crushing plant, where it is spread onto outdoor terraces and subjected to blending, grain size reduction, homogenisation and drying. Two or three layers from different extraction points are usually mixed in a final blend. Upon completion of the outdoor operations, the output goes to indoor stockpiles and finally to dry powder preparation. The average monthly production of clay exceeds 400,000 t. Most of the 20 existing mining sites are run by ceramics-owned enterprises, while the remaining manufacturers (about 40%) are supplied by independent producers.


The spread of Hongkong and Taiwan popular literature represented by the novels of Jin Yong and Qiong Yao leads to the rising of popular literature in the mainland of China.The vigorous growth of this literature and its prosperous have changed people's literature idea greatly,railsed the status of the popular literature finished the refined custom distributary,and remedied the one-sidedness of the modernity of chinese literature.It is the inevitable result of the society.This unique phenomenon of literary spread embodies several laws:firstly,modern literay spread is not without order,instead,it is going in the dirction of modernity;secondly,it is a one-way spread,but a two-way spread;thirdly,the direction of modenity decides that literature will inevitably go to the world.However,this doesn't mean literay convergence,since literature refuses globalization.The result of literary spread is not a simple assimilation,but a multiple co-existence.


Trends in the study of genetic susceptibility Genotoxicology investigates the molecular basis of cellular responses to DNA damage. During more than three decades of genetic toxicology testing, a large number of tests with varying sensitivity and specificity have been developed. These genotoxicity tests can predict: the likelihood of a substance to be a (rodent) carcinogen, the mechanism of carcinogenic activity of different substances, if the results of genotoxicity studies only predict carcinogenicity or they are a distinct hazard endpoint (Nohynek, 2005). The current genetic toxicity testing batteries represent: Ames test which is a component of all genetic testing batteries. A mammalian cell mutagenicity assay which should confirm or complete the Ames test. Chromosomal aberrations tests which are based on a different endpoint than gene mutations. Positive in vitro results need to be confirmed by in vivo tests; results from test batteries have higher predictive value than results of a single test (Nohynek, 2005).


Currently financial statements do not provide enough information about intangible resources, which makes difficult the consideration of innovation activities as strategic variables. Intangible resources are not easily detected in financial statements: some are recognized as assets, other as expenses and some are not recognized at all. Specifically, most of R&D costs are charged to expense when incurred when they really represent investments. Important achievements have been made in the development of tools which help enterprises to manage their intangible assets. However, harmonized instruments that allow the homogeneus reporting on these resources, in order to facilitate the analysis of such information by external users do not exist. A significant first step to improve the accounting system would be the disclosure of quantitative broken down information about R&D costs, either when charged to expense when incurred, or when recognized as assets.


Phosphorus separation using chemical additions to treat liquid dairy manure is a viable
and important option for manure and nutrient management. Cationic additives (ferric chloride, alum,
and lime) were used to precipitate phosphorus in liquid dairy manure with an average total solids of
2.85%. The flocs formed during coagulation were separated from the liquid by settling. After 60
minutes, settling with no chemical additions resulted in a total phosphorus reduction of 24% in the
liquid fraction. Twenty four hours of undisturbed settling reduced total phosphorus in the liquid by
60%. Three cationic additives, lime, alum, and ferric chloride, were evaluated using jar tests.
Treating the liquid manure with cationic additives resulted in a total phosphorus reduction range of 30
to 82% in the liquid after sixty minutes of settling. Total phosphorus reductions of 57 to 100% were
found after twenty four hours of settling was coupled with chemical treatment. Of the three chemical
additives tested, alum performed the best under laboratory conditions.


Abstract : The purpose of this manual is to describe from the user's perspective the automated data system that has been designed and programmed for the Statistical Retrieval System and Rate Generator (SRS/RG). The heart of the SRS/RG is a history file composed of variable length records; one record containing background information for each Marine. The records will grow as significant career events are added to the records. The significant events include reenlistments, promotions and demotions, changes in military occupational specialty, unauthorized absences and changes in duty assignments. The SRS/RG will be used by the Manpower staff of Headquarters, Marine Corps. (Author)


When my department chair and assistant principal observed my honors sophomore English class perform a scene from Othello , we all got a surprise: The students failed! The assignment did not require them to memorize lines, but only to understand them and use proper inflection. It also required them to show understanding of text and subtext through blocking, gesture, props, and ambient sound. We had spent several class periods discussing possibilities for each category and "tossing" lines. Students had asked good questions about how characters' placement on stage conveyed height, power, fall, and other dramatic elements. They had talked about using props to convey literal as well as figurative meaning. (A flashlight substituted for a lit candle as a prop for Othello's "Put out the light and put out the light" line.) So I was surprised when this group of four students stumbled over lines, didn't move, didn't use their props, and generally bored their classmates. But everyone was shocked when I didn't stop their performance. I let them fail.But I wasn't worried.Sure enough, that evening, I received nine emails from members of this class. Three of them were from the students who had failed; they had been poorly prepared and asked for another chance. The other six were from classmates offering suggestions for how the group could improve its performance.I began class the next day asking first for comments from the observers, who quickly said they had been bored. They knew that by saying this, they would be asked to help their classmates improve: It was as much their obligation to be engaged as it was the performers' obligation to engage them. After brainstorming for one class period, they came up with a method they called "Everyone Get into the Act!"The following day, each member of the class brought in an item to use as a prop. As the scene was acted out, a student in the audience yelled, "Freeze!" Then he ran into the center of the room, picked up the prop or costume piece, and placed it on or near one of the actors. While doing this, the student explained what he felt the item added to the interpretation of the lines being delivered. The actors could choose to accept or reject the item, but they had to explain their responses, again using close textual reading to support their opinion.Not only did the original group give a performance that conveyed real comprehension, but the audience ensured that they were engaged! Everyone-literally-got into the act! (The students did receive a grade for their original performance as well as for the second one.)My reluctance to intervene wouldn't have worked with every class I teach. Nor would it have worked with this class if I had taught Othello at the beginning of the school year instead of midsemester. But before we reached this point, this honors class had established a "collaborative learning environment."If this sounds a lot like "active learning," an idea first set forth back in the 1980s and popularized in the 1990s report to the Association for the Study of Higher Education (ASHE) (Bonwell and Eison 5), it is. But "active learning" focuses the responsibility for an individual's learning on the individual. A collaborative learning environment makes each individual responsible for the learning of others as well. How does this environment evolve?Getting StartedAt the beginning of the school year, I set only one ground rule: Making a contribution to class discussion is a component of the grade. "Contribution" is not only answering questions but also asking them. All comments must be supported by textual evidence. This rule ensures that students keep up with homework assignments. They must read the text to have questions about it.Sometimes, despite these "rules," some students-for myriad reasons-just won't speak up. How do we create a safe place where they actively listen and connect with the literature and with each other? …


Traditional informal description methods have obvious shortcomings in describing complex composite behaviors in MAS, not only due to their hierarchical and concurrent properties, but also for their complicated dependencies. In this paper, we propose a formal description model, MAB_CPNs, for composite behaviors among agents based on coloured Petri nets. MAB_CPNs takes data dependent relationship and control dependent relationship into consideration and provide a more comprehensive perspective on composite behaviors. We also present the basic process structure and the formal description of behavior substitution to support the hierarchical structure description of behaviors. Finally, we give a case study.

A solvothermal process was developed to in situ prepare epoxy (EP)/TiO2 hybrid precursors. The chemical structure of samples was confirmed by X-ray and Fourier transformed infrared spectroscopy. Field emission scanning electron microscope micrographs of cured EP/TiO2 hybrid composites showed that well-dispersed TiO2 nanoparticles were successfully in situ formed in epoxy matrix through the solvothermal process. The thermogravimetic analysis, DSC, and gel content measurements showed that EP/TiO2 hybrid precursors were fully cured with the glass transition temperature decreasing gradually. The effect of TiO2 contents on optical and surface properties was investigated in detail. The results indicated that epoxy/TiO2 nanocomposites exhibited excellent UV shielding effect and high visible light transparency. The contact angle of EP/TiO2 nanocomposites, when the content of silane-coupling agent (KH560) was 5 g and the content of tetrabutyl titanate (TBT) was 3 g, can reach as high as 101°, which was 36° higher than that of pure EP, representing for the increase of hydrophobicity. © 2012 Wiley Periodicals, Inc.

In this work, our purpose is investigating the behavior of simply supported steel shear walls under the monotonic and cyclic loading. First, we applied diagonal direct tensile loading on a small specimen and its behavior was compared with theoretical results. After that, we applied cyclic loading on six specimens with various dimensions and the effects of thickness, height and width have been investigated. Results have shown that, with increasing height, the drift was enhanced but a small reduction on shear strength was observed. The comparison of our results with theoretical results confirmed the validity of model. (Mohammad Bagher Mohseni. Experimental and Theoretical Investigation of Simply Supported Steel Shear

This study analyzed farmers' income between members and non-members of agricultural cooperatives in Muhanga District, Rwanda. The research used a descriptive design based on quantitative approaches; 60 cooperative members and 60 non-cooperative members which were maize farmers selected randomly in the study, plus 6 local leaders and staff of Tuzamurane Cyeza Cooperative who were used as key informants. Data collection tools were questionnaires and interviews. The collected data were analyzed by income and the independent sample t-test analysis to measure farmers' income between members and non-members of the cooperative. The findings showed that Tuzamurane Cyeza Cooperative provided services such: as easy access to credit, easy access to agricultural inputs, and acquisition of new technology and helped farmers to increase income from the cooperative. The results from the calculation indicated that the mean income of maize farmers who are members of the cooperative (Group 1), 366420 RWF is greater than the mean income of maize farmers who are non-members of the cooperative (Group 2), 137151RWF; (1RWF=14.04IDR). Further, the value of Sig. (0.047) which less than 0.05 was a good indicator that the variance in incomes of maize farmers who are members of the cooperative and non-members of the cooperative was significantly different. Our findings concluded that agricultural cooperatives' membership contributed to expanding access to markets, and people need to unite themselves in cooperatives because they play a crucial role in reducing poverty, improving food security, and generating employment opportunities.

General The connecting rod is one of the most important element of the motor, that requires a very high manufacturing accuracy. It is also one of the most complex parts, since generally the first operations of a normal working cycle are performed on connecting rod and cap separately, and the next on the two joined pieces which are then separated again to enable the mounting of the big eye to the crankshaft. For each motor the connecting rods needed are two, four or even six depending on the number of cylinders, therefore it is very important to have accurate and dependable control procedures and stations in production lines. Connecting rods are one of the few motor pieces which are asymmetric and provided with a very fast alternating motion; therefore it is very important that this part is balanced and that all connecting rods mounted on the same motor have the same geometrical and dynamic characteristics. Connecting rods are controlled not only from a geometrical point of view but also weight and weight distribution along the connecting rod body are very important and have to be controlled. The manufacturing operations of connecting rods can be different and depend on the characteristics of each production line; therefore also the control requirements can change and the measuring stations must generally be adapted to each production line. This booklet describes a selection of typical controls performed by Metrel units. This does not mean that only these can be delivered. Metrel has a wide range of available applications and has the know-how to design and create specific solution for any requirement.


It is important to investigate the phenomena in networks composed of neuron models. In our previous work, we have proposed a method to explain the phenomena in the whole network by nonlinear time-series analysis. In this study, we will clarify the relationship between the phenomena at the constituent nodes of the network and the overall phenomena.


Over the last years, cryptodatacommunications have become an important piece of evidence in criminal procedures all across the European continent. Especially due to the EncroChat- and Sky-operations, prosecution authorities were able to arrest and charge a large number of suspected criminals that probably would have remained unnoticed without the data acquired. As a result, the legality of the use of EncroChat- and Sky-data is increasingly being disputed in multiple courtrooms in various European countries. This article will therefore dive into European case law relevant in this respect and will on that basis discuss the lawfulness of both operations.


The paper describes dynamic (non-stationary) models for global telecommunication systems with changable structure and their generalizations. Optimization algorithms for dynamic, adaptive and neural routing and principles for multiagent processing of information flows in integrated infotelecommunication networks are investigated.


Background:Small amount of albumin excretion in urine, termed as microalbuminuria, has been postulated to be an indicator of endothelial dysfunction. This study was done to find the prevalence of microalbuminuria in patients with essential hypertension and to study the association of microalbuminuria with cardiovascular morbidity.Methods:This cross-sectional, observational study was conducted at the Department of Internal Medicine, Medical College and SSG Hospital, Baroda; by selecting 60 first time detected essential hypertensive patients, without any significant past or treatment history, attending Medicine outpatient department (OPD) or admitted in different wards at SSG hospital, for various reasons. A detailed history, clinical examination, basic blood investigation, urine albumin to creatinine ratio, electrocardiography (ECG) and 2D echo were done in all patients.Results:In this study, microalbuminuria was found in 24 (40%) cases with prevalence increasing with increasing age. A higher serum cholesterol, serum low density lipoprotein (LDL) and cholesterol/high density lipoprotein (HDL) ratio; left ventricular hypertrophy (LVH), ST-T changes and bundle branch block on ECG; LVH, hypokinesia and diastolic dysfunction on 2D echo; retinopathy on D fundus examination were all associated with higher microalbumin excretion in urine. Microalbuminuria was independent of age, sex, addiction to smoking, alcohol, BMI and severity/stage of hypertension. Thus, irrespective of existing known cardiovascular risk factors, microalbuminuria was associated with signs of cardiovascular morbidity.Conclusions:As a predictor of systemic vascular dysfunction, microalbuminuria can be used to stratify and prognosticate hypertensive patients at a higher risk of developing further vascular complications and they can be screened early for same.


Over the last decade various neurological disorders have been clinically treated using therapeutic deep brain stimulation (DBS). A fuller understanding of the role of modulating brain activity by electrical current will provide a rational basis for the optimisation of therapeutic effects. It remains unclear how the electrical current injected via the implanted depth electrodes is distributed locally or globally in the brain. This is largely because direct measurement of the distribution is difficult or almost impossible. A limited attempt has been made by some researchers to model the static conditions; however this does not include the dynamic features of the stimulation current. Additionally, the need for geometrically accurate finite element meshes of the adult human head is now becoming more acknowledged, and some investigations have been carried out to establish methodologies for their generation. This paper presents a new dynamic model of the whole human head using a geometrically accurate forward model that includes scalp, skull, CSF and brain with the correct conductivity parameters. Results of 10 Hz sinusoidal stimulation, simulating the therapeutic frequency ranging from 10 to 200Hz, in a case of DBS of the subthalamic nucleus for Parkinson's disease are presented. These results will be validated from measurements taken from both scalp and depth brain electrodes.


Sleep is a reversible behavioral state shutdown of perception and relative absence of the environment. Insomnia is related to the quality, duration and continuity of the sleeping, affecting mainly the women, having as one of the determining factors, periods of intense fluctuations or variability hormonal, observed during pregnancy. Given the correlation of insomnia with the gestational period, this study evaluated the efficacy of massage therapy as a therapeutic way in insomnia during pregnancy. Massage therapy is an important source of healing, having mechanical effects, physical and psychological. The present study this is an interventional study, the sample was accessibility, with only one participant, the pregnant patient, she is 26 years old, multiparous, 30 weeks of gestation, complaining of insomnia, served in the Department of Physiotherapy of the Institute of Health Elpídio de Almeida (ISEA) in Campina Grande Paraíba. As an instrument for datas collection of the patient, it was used the Epworth Sleepiness Scale (ESS BR) and Pittsburgh Sleeping Quality Index (PSQI BR). In the first meeting was made an evaluate being applied to ESS BR getting 19 points and PSQI BR getting score 12, indicating severe drowsiness and poor sleeping quality. Then it was applied the classic protocol massage for insomnia, adapted from Domenico and Wood (1998), with two weekly sessions, totaling eight massage sessions during thirty minutes each. After 08 sessions, the patient was reevaluated by ESS BR getting 12 points changing from serious to excessive sleepiness and by PSQI BR getting score 08, not changing the quality of sleeping, staying poor.


Low calcium content in pineapple could decrease its quality, such as fruit translucency (electrolyte leakage), bruises (fruit firmness), and the other fruit quality standards. The purpose of the current study was to assess the effect of different sprays of calcium (Ca) fertilizer sources during the fruit development stage on the overall fruit quality. Four sources of calcium, chelated calcium, calcium nitrate (Ca(NO3)2), calcium chloride (CaCl2), each in 75 kg ha−1, and calcium boron (calcibor) of 10 L ha−1 mixed with 2000 L water, were directly sprayed onto individual fruit and crown, 75, 85, 95, and 105 days after forced flowering induction (forcing). The Smooth Cayenne "MD-2" pineapple cultivar was utilized for the experiment in a randomized complete block design with four replications and conducted at two different times. Fruit quality analyses were carried out on the harvested fruits 140 days after forcing. The application of calcium sprays did not have significant effects on fruit

 , total soluble solids, total acidity, fruit firmness, and the content of sucrose and vitamin C. There was a different response of calcium spray in the first and second trials on the content of glucose, fructose, β-carotene, Ca, and Mg, probably due to climate condition. All treatments with calcium sprays reduced the fructose and glucose contents in the first trial and β-carotene content in the second trial. Calcium chloride and calcibor increased Ca and decreased electrolyte leakage significantly than the other treatments. The scanning electron microscope analysis revealed that CaCl2 sprays generated greater turgor and more rigidity in the pineapple cell wall. The result showed that the application of CaCl2 and calcibor sprays could decrease electrolyte leakage incidence in pineapple with any potential to reduce glucose, fructose, and β-carotene without influencing other fruit qualities significantly.


The term Computer Algebra System (CAS) is commonly applied to such mathematics packages as Maple, Mathematica, Macsyma, Reduce, Derive and perhaps Mathcad. This reflects their origins as programs for manipulating symbolic expressions for research purposes, rather than being descriptive of what they have become. With their graphical, numerical and presentational capabilities, these packages could now more accurately be described as "Systems for doing, applying and demonstrating Mathematics" – a variant of Stephen Wolfram's original sub-title of Mathematica. As a consequence of the blending of these separate facilities, the latest CASs are very powerful tools for teaching and learning mathematics.


Abstract Paulownia Siebold et Zucc., a widely distributed native genus, has been commonly used in the furniture. The color of wood is a very important aesthetical property, and it has a fundamental influence on the commercial value of timbers. Therefore, it is critical for forest managers to select elite Paulownia clones based on the color of wood. Eighteen 5-year-old Paulownia clones grown in a hilly area in Hubei Province, China were examined in terms of color values (L*, a*, b*), color difference (ΔE*), and Hunter lab space whiteness (W) using a Chroma meter CR-400. Differences in color parameters among the 18 clones were analyzed and clustered. The results showed that the ranges of L*, a*, b*, ΔE*, and W were 77.19-80.38, 3.60-4.84, 13.79-15.69, 17.92-21.37, and 68.92-72.42, respectively. The color parameters significantly differed among the examined clones. Differential and cluster analyses indicated that clones 204, 605, 702, and 603 had higher L*, W, and lower ΔE*, rendering these as elite clones with superior color properties.

The collision-energy and orientation-angle-resolved Penning ionization cross section was determined for the Ar(3P)+CH3Br reaction by using an oriented beam and a time-of-flight measurement. A remarkable resonance-type structure in the Penning ionization cross section is recognized in the collision energy dependence at fixed molecular orientations, which is very similar to the one we previously observed in the Ar(3P)+CH3Cl reaction. This resonance-type structure could be interpreted as a new type nuclear-excited Feshbach resonance where the branching to competitive neutral dissociation channel is enhanced due to the formation of vibrationally excited CH3Br Rydberg states.


A potential model based on quantum-chromodynamics (QCD) considerations is developed. The model attempts to overcome the relativistic limitations associated with earlier models by introducing an effective size for quarks. Application of the model Hamiltonian to both light and heavy mesons yields an accurate description of the mass spectrum, radiative transitions, and annihilation widths for a large number of known mesons. Spin-dependent interactions are treated nonperturbatively using standard diagonalization procedures with an oscillator basis set and relativistic kinematics are adopted throughout. The scaling of the potential parameters is found to be similar to simple QCD predictions. Much of the anomalous behavior for pseudoscalar mesons appears to be resolved both for light and heavy mesons.


In this paper, a convergent method based on Generalized Iterative Scaling (GIS) with staggered Aitken acceleration is proposed to estimate the parameters for an on-line Conditional Random Field (CRF). The staggered Aitken acceleration method, which alternates between the acceleration and non-acceleration steps, ensures computational simplicity when analyzing incomplete data. The proposed method has the following advantages: (1) It can approximate parameters close to the empirical optimum in a single pass through the training examples; (2) It can reduce the computing time by approximating the Jacobian matrix of the mapping function and estimating the relation between the Jacobian and Hessian in order to replace the inverse of the objective function's Hessian matrix. We show the convergence of the penalized GIS based on the staggered Aitken acceleration method, compare its speed of convergence with those of other stochastic optimization methods, and illustrate experimental results with two public datasets.


Abstract The microsporidian parasite Encephalitozoon cuniculi commonly infects rabbits. Most infections are initially asymptomatic, but for reasons yet to be explained, many rabbits subsequently develop disease as a result of infection with this organism. Three common forms of this disease are recognized, and they can occur individually or in combination. The ocular form is associated with cataracts and when there is extensive damage to the lens, uveitis. The neurological form can vary from a mild change in the rabbit's behavior to severe vestibular disease. The signs associated with the renal form of the disease are those of chronic progressive renal disease. Definitive diagnosis of encephalitozoonosis in the rabbit is difficult. Animals with encephalitozoonosis are expected to be seropositive, but many apparently healthy rabbits are also seropositive, so this assay is not specific and its results must be considered in the light of other diagnostic findings. The absence of antibody, however, should cause the practitioner to consider other differentials. Drugs proven to be efficacious for E. cuniculi infections include albendazole and fenbendazole. Supportive care and treatment with antiinflammatory medications may also be necessary in some forms of encephalitozoonosis. Lens removal or removal of the lens contents is indicated in some rabbits with E. cuniculi -induced ocular disease.


The air container CT inspection system has been developed as a high space-resolution, high density-resolution CT scanner. The design of CT reconstruction software based on the system uses the back project algorithm to construct the CT images, and the filter functions are also included to process the CT data. Because the system can be used to inspect the large objects that cannot be penetrated easily by gamma-ray, the reconstructed CT images may have some artifacts that may damage CT image. The digital subtraction method is used to realize the CT reconstruction for the edge parts of large object that has big gamma-ray attenuation in the center part of the object. The nonlinear effect while measuring is corrected using serials of thin ion plates. The CT images for large objects are improved obviously by using the plate correction. The CT images based on the back project algorithm are also obtained by using the non-perfect projection data. The obtained CT image can have a certain precision to meet the demand. And the principal of the CT reconstruction using the non-perfect project data is also analyzed. The noise influence to the CT imaging quality is also analyzed. Different kinds of noises were added to the signals of all channels or selected channel. The experiment showed that the CT construction realized by the paper has high density resolution and high spatial resolution. The designing for CT construction software is successful.Copyright © 2009 by ASME


Objective To observe the urinary trans,trans-muconic acid(t,t-MA)variation in rat models dynamically exposed to benzene,and to investigate the feasibility to taking urinary t,t-MA as the biomarker in benzene exposed.Methods forty-eight adult Wistar rats were randomly divided into 4 groups:the control group,low-,middle-and high-dose group.The exposed groups were dynamically exposed to benzene for 28 days(4 periods)and the concentration were monitored.The rat urine was immediately collected after each period and detected by the reverse phase high performance liquid chromatography /mass ultraviolet detector methods,t,t-MA level was adjusted by urine creatine.Results The rat urinary t,t-MA increased along with the increase of environment benzene in each period and had significantly differences the different exposed groups(P0.05),and did not significantly change along with the exposed time course(P0.05).Conclusion The rat urinary t,t-MA may be a sensitive biomarker of benzene exposed.


. Matrix polynomials with unitary/doubly stochastic coefficients form the subject matter of this manuscript. Bounds on the eigenvalues of matrix polynomials with doubly stochastic coefficients (under certain assumptions) are derived. We also prove that if P ( λ ) is a regular quadratic monic matrix polynomial whose coefficients are either unitary matrices or doubly stochastic matrices, then under certain conditions on these coefficients, the corresponding block companion matrix C is diagonalizable. Consequently, if Q ( λ ) is another regular quadratic monic matrix polynomial with corresponding block companion matrix D , then a Hoffman-Wielandt type inequality holds for the block companion matrices C and D . coefficients; Diagonalizability of block companion matrix; Coneigenvalues and condiagonalizability of block companion matrix; Hoffman-Wielandt type inequality.

In order to study the distribution of hazardous elements in combustion residues of fuel coal and in other solid by-products in thermal power plants,and their influence upon the surrounding environment,some fuel coal and their solid by-products,i.e.fly ash,slag,gypsum in wet FGD,and sludge in wastewater of FGD etc.,in a few coal-fired power plants have been sychronously sampled,and a set of test methods more appropriate to application being formulated according to relevant testingstandards,the hazardous elements in said samples,i.e.chronium,cadmum,lead,arsenic,and mercury,being tested,and the test results being analysed by using statistical examination method,so as demonstrate whether the non-solid substances exist in each hazardous element after combustion,and to examine the enrichment behavior of each hazardous element after combustion.Thereby,the migration rules of hazardous elements in fuel coal during combustion process in thermal power plants have been demonstrated.Results of study show that the content of heavy metal elements in fly ash and sludge is relatively higher,and having large tendency to environment pollution,it is recommended to adopt measures for preventing said elements from entering into the surface water to pollute the environment.Moreover,the problems related to environment protection regulations currently in effect for hazardous elements emission from thermal power plants have been discussed,and it is suggested to strengthen the detection of hazardous elements in solid by-products resulting from operation process of power plants and the post-evaluation work.


The time-temperature dependent Perminvar effect in amorphous Co/sub 100-x/B/sub x/ (x=17-30 at%) alloys was investigated in the temperature region of 150 to 450 K for stabilization times of up to 12 hours. After stabilization of the demagnetized domain structure the AC susceptibility (permeability) dependent on the driving magnetic field H shows a constant value up to the Perminvar critical field H/sub CR/. The fact that H/sub CR/ in CoB alloys can be higher than coercive field H/sub C/ is rather curious. In the Co/sub 75/B/sub 25/ alloy H/sub CR/ reaches values of 1.5 to 56 A/m dependent on the time and temperature of the stabilization. From the relative difference between two values of H/sub CR/ measured at two times t/sub 1/ and t/sub 2/ a magnetic relaxation spectrum similar to that obtained from reluctivity have been constructed. The kinetics of the H/sub CR/ increase measured at different temperatures indicates that relaxation parameters are equal to those obtained from the magnetic reluctivity aftereffect and that both effects have the same inherent nature. >

AbstractObjective: The present study aimed to explore the roles of social identity (British Asian / TGNC)against mental health problems (depression) and well-being.Methods: This study is a mixed methods pilot study. British Asian TGNC adults were our targeted subjects. An online anonymous survey was opened for four weeks and shared by some LGBTQ+ communities in the U.K. We recruited three participants, which did not meet planned sample size requirements.Results: Due to the lack of participants, we cannot reject our support any of our hypothesis. Based on the qualitative analysis, we inferred some possible findings: (1) double stigmatized individuals reported great experiences of discrimination related to their stigmatized social identity; (2) people who hold double stigmatized identity may show asymmetric identification; (3) affirmation of multiple identities could provide resilience and then foster mental health and well-beings.Conclusion: Our study demonstrated the difficulties in recruitment double minority group of people. The reasons of the failure in recruitment could be (1) double stigmatized identity may lead to concealment (2) COVID-19 causes problems in direct contact. Implications on recruitment issues within double stigmatized identities are extensively discussed, with discussions against how these areas relate to effective contact and engagement with specialist service for British Asian TGNC individuals and communities. Having a theoretical and practical understanding of these issues may address future recruitment difficulties
