Abstract Widespread concerns about the spread of misinformation have gained urgency during the ongoing COVID-19 pandemic and pose challenges for science journalism, in particular in the health area. This article reports on a Research through Design study exploring how to design a tool for helping readers of science journalism understand the strength and uncertainty of scientific evidence in news stories about health science, using both textual and visual information. A central aim has been to teach readers about criteria for assessing scientific evidence, in particular in order to help readers differentiate between science and pseudoscience. Working in a research-in-the-wild collaboration with a website for popular science, the study presents the design and evaluation of the Scientific Evidence Indicator, which uses metadata about scientific publications to present an assessment of evidence strength to the readers. Evaluations of the design demonstrate some success in helping readers recognize whether studies have undergone scientific peer review or not, but also point to challenges in facilitating a more in-depth understanding. Insights from the study point to a potential for developing similar tools aimed at journalists rather than directly at audiences.


In this paper, we present an approach to capture markerless human motion and recognize human poses. Different body parts such as the torso and the hands are segmented from the whole body and tracked over time. A 2D model is used for the torso detection and tracking, while a skin color model is utilized for the hands tracking. Moreover, 3D location of these body parts are calculated and further used for pose recognition. By transferring the 2D and 3D coordinates of the torso and both hands into normalized feature space, simple classifiers, such as the nearest mean classifier, are sufficient for recognizing predefined key poses. The experimental results show that the proposed approach can effectively detect and track the torso and both hands in video sequences. Meanwhile, the extracted feature points are used for pose recognition and give good classification results of the multi-class problem. The implementation of the proposed approach is simple, easy to realize, and suitable for real gaming applications.

The inhibition of the corrosion of C38 steel in sulfuric acid solution by the essential oil of Eucalyptus globulus (Myrtaceae) has been studied using weight loss, electrochemical impedance spectroscopy and potentiodynamic polarization techniques. Inhibition was found to increase with increasing concentration of the essential oil. The effect of temperature on the corrosion behavior of C38 steel in 0.5M H2SO4 with addition of essential oil was also studied. The adsorption of the essential oil on the C38 steel surface obeyed the Langmuir adsorption isotherm. Values of inhibition efficiency calculated from weight loss, potentiodynamic polarization, and electrochemical impedance spectroscopy are in good agreement. Polarization curves showed that Eucalyptus globulus (Myrtaceae) essential oil behaves as a mixed-type inhibitor in sulfuric acid. The activation energy as well as other thermodynamic parameters for the inhibition process was calculated and discussed. The results obtained showed that the essential oil of Eucalyptus globulus (Myrtaceae) could serve as an effective inhibitor of the corrosion of C38 steel in sulfuric acid solution.


Summary

This paper describes the habitat preferences of small rodents and shrews from April 1984 to March 1985 in four types of vegetation in a lowland rain forest zone of Nigeria. The vegetation types were high forest, scrub, farmlands and teak plantations in Ogba Forest Reserve, Nigeria.

A collection of 359 small mammals, consisting of six species of small rodents and four species of shrews, was made in the study area. The small rodents and their percentage composition were Mus musculoides (26.2%), Praomys tullbergi (16.2%), Mastomys natalensis (7.0%), Lophuromys sikapusi (4.5%), Lemniscomys striatus (2.5%), and Arvicanthis niloticus (1.1%). The shrews were Crocidura nigeriae (19.5%), C. crossei (12.3%), C.grandiceps (7.8%) and C. ftavescens manni (3.1%).

The vegetational distribution of the small rodents and shrews is discussed. In the high forest, seven species of small mammals were caught; these were Crocidura nigeriae, C. crossei, C.grandiceps, C.flavescens manni, Mus musculoides, Praomys tullbergi and Lophuromys sikapusi. Mus musculoides, Crocidura nigeriae and Praomys tullbergi were more abundant in the high forest.

All the species of small mammals recorded in the study area, except Arvicanthis niloticus, were found in the scrub. In the farmlands, all ten species of small mammals were trapped. Mus musculoides was the commonest species in the farmlands. Three species of shrews, Crocidura crossei, C. grandiceps and C.flavescens manni, and also two species of small rodents, Mus musculoides and Mastomys natalensis were caught in the teak plantation.

The reproductive data for Mus musculoides, Crocidura nigeriae and Praomys tullbergi show that breeding in these species occurs throughout most months of the year. Fecundity appears to be maximal in the wet season in Mus musculoides and Crocidura nigeriae and in the dry season in the case of Praomys tullbergi.


quinone determined in the petroleum ether extracts, and the specific activity of the chromato- graphed ubiquinone. In the experiments with p-hydroxybenzaldehyde-U-C'4 and p-hydroxy-benzoic acid-U-C'4, estimates made in this way agreed fairly closely with the total amount of radioactivity found in the petroleum ether extracts. carrier, the ubiquinone benzo- quinone ubi-quinone-9, ubiquinone-8, the homologue occurring ubiquinone-9 was substituted. It was assumed that a small dif- ference in the length of the side chain would not influence the course of the degradation. In the degradation, the ubiquinone was reduced with Na2S204, and acetylated with acetic anhydride,"3 and the dihydrodiacetyl derivative was ozonized by the method of Bentley et al.'4 From the side chain, the degradation yields levulinaldehyde, which was converted to the bis-dinitrophenyl- hydrazone. This derivative was recrystallized from chloroform, plated on a weighed filter paper, and the C'4 was determined in a gas flow counter. The 2,5-diacetoxy-3,4-dimethoxy-6-methyl- phenylacetic acid obtained from the benzoquinone ring'3 was sublimed, crystallized from ether, determined by titration, and its radioactivity was measured in the scintillation counter.

Unmanned aerial vehicles (UAVs) have been spread into various markets, such as logistics. The UAVs are requested to be safely flying above densely populated areas. Electromagnetic interference (EMI) problems can become prominent within their compact chassis where multiple electronic modules are densely packed. This paper presents the EMI evaluation between IC chips and wireless communications inside an industrial UAV. Also the two main sources of electromagnetic (EM) waves, power modules and control modules, are explored in respective dominant frequency ranges with near-field EM measurements up to 5 GHz. The influence on cellular communication performance was evaluated with a wireless communication system level simulator, predicting the degradation by 9 dB in the minimum receiver sensitivity of long-term evolution (LTE) communication system even if a receiver module is mounted at 200 mm distance in the chassis.


ABSTRACT The purpose of this study was to scrutinize the Playground Movement through the lens of eugenics. The theoretical relationship was clear because of the dominant influence of inheritance-driven theories that stressed the role of play in developing desirable traits. Progressive Era emphasis on race betterment provided an optimal environment for the use of eugenic practices to correct flawed members of society; the emphasis on guided play satisfied this need. Playground leaders were also challenged by threats to its credibility from sequestration measures – ugly laws and discrimination. This forced them to defend play using instrumental definitions and caused them to acquiesce to segregated arrangements for the defective and diverse of society at times. Eugenic-like strategies were reflected in trying to normalize development of children through retracing the evolutionary trail of the race, altering future generations' DNA profile, and as an attempt to repair the faults and failings of the current generation.

Bird flu infection processes within a poultry farm are formulated mathematically. A spatial effect is taken into account for the virus concentration with a diffusive term. An infection process is represented in terms of a traveling wave solutions. For a small removal rate, a singular perturbation analysis lead to existence of traveling wave solutions, that correspond to progressive infection in one direction.


: Quality education is a localized concept in China, and the history of quality education in our country can be traced back to the 1980s. After decades of development, catalyzed by various factors, including the current period of social transformation, quality education has evolved from its inception to become a hot topic in educational reform and a subject of significant interest in the media. The implementation of quality education has played a vital role in promoting reform in China's primary and secondary education. However, it has also exposed numerous issues. This article analyzes the experience of quality education in foreign countries and discusses the problems and solutions concerning quality education in primary and secondary schools.


Since 1997, the USDA/National Agricultural Statistics Service (NASS) created an annual cropland classification known as the Cropland Data Layer (CDL) using thirty meter Landsat TM and since 1999, the ETM+. Historically, the Landsat 5 and 7 satellites provided adequate temporal coverage to create the CDL products with a high degree of reliability and statistical accuracy. Due to the uncertainty of the availability of TM 5 data for the 2006 crop growing season, USDA and NASS have been using AWiFS as a primary imagery source. In 2005, there was sufficient cloud-free imagery to cover most of Nebraska with multitemporal TM, using 31 scenes forming 7 analysis districts and multitemporal AWiFS, using 7 scenes forming 3 analysis districts. Both sets of data were processed separately using the same methodology that was used to create the NASS CDL. The CDL is created by ISODATA clustering of known cover types by analysis district from a statewide coverage of 470 segments representing 650 square miles and applying a maximum likelihood classifier. Crop coverage estimates are generated by analysis district using in order of preference: regression, pixel ratio or direct expansion. Analysis districts are mosaiced and clipped to minimize clouds and maximize higher quality classification. This analysis will compare the percent correct, Kappa accuracies, and regression estimates by analysis district and at the state level. Preliminary results show that although the quality of the AWiFS estimates are not as high as TM they will still provide valuable statistics to the NASS estimation program and warrants continued investigation into this sensor.


The ultraviolet spectrum of the periodate ion IO–4 in several solvents has been resolved into two overlapping gaussian bands, one close to 222 nm (Iµmax= 1.0 × 103 m2 mol–1) and the other close to 280 nm (Iµmax= 27 m2 mol–1). Both bands undergo small blue shifts in more polar solvents and it is concluded that they are due to π*→π* and n→π* transitions, respectively. The shift in going from acetonitrile to water is negligible, confirming that hydrogen bonding of the ion to water is weak. The diffuse reflectance spectra of solid NaIO4 and KIO4 show bands at ≈ 215, 290, and 330 nm.


Objective To know the situations about tutors and tutors training of general practice in mainland. Methods To investigate the directors of all provincial general practice training centers in mainland by using structured questionnaire. Results The educational level of all kinds of tutors was good, but the other aspects of all kinds of tutors such as the source, the training time, the continuous education, the training goal, the training content, the examination should be standardized. Tutors' training of general practice had been launched in 20 general practice training centers, but the training time was brief and the trained people was few in 10 general practice training centers. Conclusion The qualification of tutors should be developed and the administrative system of tutors should be built.


In nonlinear recursive Bayesian state estimation, it is in general intractable to maintain the exact posterior density for the state. In order to obtain an approximate solution, it is common to (re-)approximate the posterior density with a Gaussian density. In this paper, we investigate the use of deterministic samples generated by herding in Gaussian filters. Herding is a (relatively) computationally cheap procedure to sequentially generate deterministic samples from probability density functions. We demonstrate the practicability of herding in sample-based nonlinear Kalman filters and Gaussian particle filters in two challenging tracking scenarios.


Abstract We propose a novel edge detector in the presence of Gaussian noise with the use of proximal support vector machine (PSVM). The edges of a noisy image are detected using a two-stage architecture: smoothing of image is first performed using regularized anisotropic diffusion, followed by the classification using PSVM, termed as regularized anisotropic diffusion-based PSVM (RAD-PSVM) method. In this process, a feature vector is formed for a pixel using the denoised coefficient's class and the local orientations to detect edges in all possible directions in images. From the experiments, conducted on both synthetic and benchmark images, it is observed that our RAD-PSVM approach outperforms the other state-of-the-art edge detection approaches, both qualitatively and quantitatively.


THE TEACHING OF CONTEMPORARY FRENCH CULTURE has largely replaced the teaching of French civilization in first-year textbooks. Twenty-five years ago a beginning student would learn about les anciennes provinces, Jeanne d'Arc, Fragonard, and Jean-Paul Sartre. Today the photographs of Chambord and Chartres have given way to reproductions of billboards, television schedules, official documents, and scenes of ordinary people doing everyday things. This shift represents on one level an effort to make language study practical and contemporary. It clearly illustrates the influence of American culture's fundamentally pragmatic nature on the language classroom. From a slightly different perspective, the new emphasis parallels the evolution of education from schooling the elite in what the faculty felt they "should" know to training all levels of society in what the faculty feels they "want" to know. Contemporary culture is definitely a part of the moder French curriculum. Although it may not yet have the prestige of high culture in the minds of some, it need not be poorly or superficially taught. In addition to the cultural notes, readings, and realia that abound in recent textbooks, there are many experiential or participatory techniques to which the teacher may turn for the sake of variety.1 Among these techniques is the culture assimilator or cultural mini-drama, as it is sometimes called. Originally, a culture assimilator referred to a set of seventy-five or one hundred critical incidents or mini-dramas. But for the purposes of this essay, the whole will signify the part, and the term "culture assimilator" will designate a text composed of three parts: 1. a narrative or dialogue of some intercultural encounter (the critical incident per se); 2. four alternative interpretations of the encounter; and 3. four feedback explanations detailing why each alternative is right, wrong, or simply inadequate. Laurence M. Stolurow, a psychologist interested in programmed learning, developed the culture assimilator in an attempt to assist "members of one culture to interact and adjust successfully with members of another culture."2 Working with the Advanced Research Projects Agency from 1962 to 1967, Stolurow first created assimilators for the Arab culture and tested them using fourteen male members of the University of Illinois Arab Student Association.

The downstream effects of pH modulation significantly impact the biological fate of chemotherapeutic agents and tumor responsiveness to therapy. We have studied the effects of cesium chloride (CsCl) on pH modulation and subsequent vitamin D treatment in vitamin D receptor (VDR) positive LNCaP tumors and VDR null MDA/LCC6 tumors in vivo.


Human manner of walking characterized by kinematic parameters measure posture-gait control characterizing the dynamic changes in body parts with the involvement of multi-sensory patterns processed by different parts of the brain. In this study, low-cost sensors have been used to collect gait signals and identify the features responsible for differentiating the gait phases (swing/stance). Dataset was obtained for a total of 160 trails with 5 gait cycles per trail from healthy volunteers $(\mathbf{n}=20)$. Torque involved during progressive gait was also estimated to model regulation of the body for maintaining balance in gait and posture. Additionally, we also investigated EEG and gait correlates by identifying the brain regions that are active during movement initiation and during stance and swing (a progressive gait) using electroencephalography. While identifying key biomarkers relevant for posture control and gait, this could enhance low-cost detection of movement related diseases in technically challenged regions.

In this paper a computational method is introduced for simulating the motion of the particles in tidal flow. This method is optimized by using the limit of stability of the numerical tidal model. Visual Fortran is selected to accomplish the program. The motion of the particles in the Bohai Sea is studied by using this method, and some useful results have been obtained.


This paper aims to explain the relationship between learning organisational practices and dimensions of organisational commitment. Two separate instruments were developed for the purpose of the research. The first instrument consisted of twenty-one items and was used for measuring seven learning organisational practices namely continuous learning opportunities, dialogue and inquiry, team learning and collaboration, empowerment, embedded systems, systems connection, and strategic leadership. On the other hand, the second instrument consisted of twenty-four items and was used for measuring three dimensions of organisational commitment namely affective, normative and continuance commitment. The data was collected from 270 employees of the IT sector at two different points in time. Three separate Multiple Regression Analyses were used as the statistical technique. Results indicated that six of the seven learning organisational practices included in the study, namely continuous learning opportunities, dialogue and inquiry, team learning, and collaboration, empowerment, embedded systems, and systems connection are significantly related with the affective commitment. On the other hand, six of the seven practices included in the study namely continuous learning opportunities, dialogue and inquiry, team learning, and collaboration, empowerment, embedded systems, and systems connection have a significant relationship with the normative commitment. Last but not least, five of the seven practices included in the study, namely continuous learning opportunities, dialogue and inquiry, team learning, and collaboration, empowerment and systems connection have a significant relationship with the continuance commitment.


For years the only serious question about district attorney elections was whether they were pernicious or merely a charade. One view was that running for reelection turned prosecutors into politicians, and that politics demanded that prosecutors appear tough, unforgiving, and staunchly pro-police. The rival view was that prosecutorial elections were meaningless, because incumbents hardly ever lost, and campaigns focused on personalities, not on policies. Recently, though, a surprising number of district attorneys have won office by promising some combination of less aggressive charging, more vigilance against wrongful convictions, and greater scrutiny of the police. This essay examines these results and draws three tentative lessons. First, claims about the inexorable logic of criminal justice politics should be greeted with skepticism. Second, there is room for guarded optimism about electoral democracy as a tool for reforming prosecutors' offices, but voters need better tools for evaluating how those offices are performing. Third, as reformers increase their focus on prosecutorial elections, there is a danger worth bearing in mind: the risk that prosecutorial decision-making will become inappropriately politicized, especially when elections focus on the handling or the outcome of particular cases.


The acuteness of information asymmetries between bankers and entrepreneurs, which cannot be offset by adequate loan securitization, constitutes one of the main stumbling blocks to SME financing in SSA. The gap between banks and SMEs can, however, be narrowed by developing financial systems that are more adapted to local contexts. In addition, by promoting sustainable guarantee funds, banks would be able to share their risks.


The article presents a basic outline of appellate jurisdiction in Early Stuart England. From the days of the Norman Conquest appeal was possible from the English courts of the civil and canon law to the court of Roman curia (Rota Romana), but the Reformation changed the established process crucially. The Ecclesiastical Appeals Act (otherwise Act of Appeals) and Act for the Submission of the Clergy (1533) strictly prohibited any appellation to Rome and made the Crown the one and final appellate institution for the English people. For the Common law courts the final appellate court was the King-in Parliament; for Equity courts it was Lord Chancellor or the Privy Council. For the Civil law courts and Canon law courts a new institution was established. The High Court of Delegated was not a permanent judicial body but a commission nominated by the Crown from the nobility, civilians and common law judges. From the late Tudor period until the English Civil war civil lawyers actually dominated the court, developed its procedure and juridical principles.


India is a country with enormous requirements of infrastructure development and up-gradation. The development of the country depends on building sustainable infrastructure with a challenge of getting it done real fast to catch up with the huge and rising demand. The role of the construction industry in the economic growth of a country is enormous and immeasurable. The challenge of providing needed quality infrastructure is in the hands of construction Industry. However in our country, almost all construction projects, suffer major delays and cost overruns. In some cases get terminated midcourse and do not get completed at all. Out of the total 766 central projects of value Rs 150 crore and more, 237 projects are delayed (~30.94%), while the cost of these projects have gone up from 10,68,206.97 crore to 12,73,650.02 crore (~19.20%)1. The reasons for the delays and cost overruns on these projects are plenty. Delay in land acquisition, right of access, delayed financial clearances, delayed/in adequate designs, scope creep, incorrect estimates, etc. to name a few.


The aim of this study was to identify the incidence, clinical features, and prenatal risk factors for hypertensive disorders, including gestational hypertension (GH) and pre‐eclampsia (PE), in twin pregnancies.


A switching system (10) is modified to provide, in addition to conventional connections (110 + 111) between ports (100, 103), eavesdropping connections that couple only one-half of a conventional bidirectional connection between a pair of ports to a third port (102). If the pair of ports serves an adjunct processor such as a voice-mail system (11) and a user voice terminal (13), a voice- or speech-recognition unit (12) serving the adjunct processor may be connected to the third terminal to receive thereat only the transmissions (112) of the user voice terminal without the unwanted transmissions of the adjunct processor. If the transmissions of the user voice terminal are polluted with echoes of the adjunct processor transmissions, then each half of the conventional connection between the adjunct processor and the user voice terminal may be connected to a different one of two ports (102, 103) serving the voice- or speech-recognition unit, whereby the recognition unit is able to receive the polluted transmissions (112) of the user terminal separately from the transmissions (113) of the adjunct processor and use the latter to perform echo cancelling functions on the former so as to obtain only the transmissions of the user voice terminal without the unwanted transmissions of the adjunct processor.


Abstract : A five-month study was performed on an energetic, dissipative beach on a climatologically Mediterranean coastline to explore the wind stress and buoyancy flux. An eddy covariance system was deployed in the intertidal zone resulting in 1088 hours of quality-controlled flux observations at elevations of 1, 3, and 6m on a sandy beach in Monterey, CA. The wind stress angle relative to the mean wind direction varied as much as 31 deg, representing one standard deviation, with a range of 151 deg. The variations were dependent on the wind angle relative to the swell direction and shoreline, which directed the stress vector to the left for winds approaching from 0 deg -45 deg and to the right for winds approaching from -45 deg -80 deg, where 0 deg is onshore. The stress angle was independent of stability, stress, and wind speed. Air-ocean temperature differences produced unstable conditions 88% of the time in contrast to the near neutral conditions that dominate the open ocean. Based on flux footprints, the surf zone was found to be a source of positive buoyancy and heat flux contributing to the unstable conditions. Minimum buoyancy fluxes were observed with the flux footprints that were farther offshore centered outside the surf zone, resulting in stable conditions.


BACKGROUND

In nuclear medicine, the discharge of the radionuclides waste into the environment can cause serious environmental problems. It is preferable to remove these radionuclides from aqueous waste before discharging. Biosorption as an alternative has been becoming more important. The aim of the present work is to remove radioactive Tl-201 by biosorption from the aqueous media using the solid waste of an oleum rosea processing plant as a biosorbent.

RESULTS

Radioactive Tl-201 was removed from aqueous solution by biosorption in a stirred batch process with experimental parameters pH, temperature, adsorbent dose, nominal adsorbent size, and stirring speed. The effectiveness of the parameters in decreasing order was found to be initial pH, particle size and adsorbent dose. The biosorption yield is slightly reduced with increasing temperature, and no considerable effect of stirring speed was observed. The process is multi-layered on the heterogeneous surface and has a physical character. Negative ΔG showed that the process is spontaneous, and negative ΔH indicates that the process has exothermic character.

CONCLUSIONS

The process has serious potential because of its fast biosorption rate with an equilibrium period of about 10 min and high biosorption yields up to 93%. © 2013 Society of Chemical Industry


Background: Granulomatosis with Polyangiitis (GPA) is a necrotizing granulomatosis vasculitis that may influence most organs, but posterior pituitary involvement as the first manifestation is unusual. However, there are some case reports in this regard. Case presentation: A 49-year-old menopausal woman presented with polyuria, polydipsia and weight loss over time headache, purulent nasal discharge, malaise, ear pain developed. After right myringotomy due to secretory otitis media and nasal cavity biopsy, the symptoms exacerbated. Diabetes insipidus was documented by Deprivation test. Thus, 20 microgram nasal spray DDAVP was prescribed. Pituitary MRI +/- Gad demonstrated pituitary involvement. Pituitary axis hormone evaluation was consistent with menopausal state. Chest spiral CT scan showed speculated border soft tissue mass lesion. GPA confirmed with ACR criteria and C-ANCA positive. Therefore, corticosteroid and rituximab were started. Symptoms of DI responded well to the treatment and the spray dosage was decreased. Conclusion: DI can be the first manifestation of GPA; although it is rare, it is worth to be diagnosed early and serious treatment of vasculitis should be started to prevent irreversible damage to the hypophysis cell and unnecessary procedure. Keywords: GPA; granalomatosis vasculitis; diabetes insipidus.


At a wedding there is a guest book to fill in so that the party organizers find out who the guests are. The length of filling in the guest book makes the queue quite long. The purpose of this study is to design and build an application system for android guest-based data collection using the QR Code that is used to replace the guest book filling. The research begins by designing ERD and Activity Diagrams. Then it is implemented into two programming languages namely PHP and Kotline and MYSQL database. Based on the results of the study, the author has succeeded in building an android-based guest guest data collection system application using the QR Code.


The so-called nonorthogonal or unequal n's analysis of variance continues to be an area in which settled opinion apparently is absent. The lack of agreement is more apparent than real and probably results from a failure systematically to address and distinguish among certain logical, statistical, and computational problems that tend to disappear in the case of equal n's but not otherwise. In particular, confusion has been fostered by naming results rather than stating in an unambiguous form the hypotheses being tested. Some elementary mathematical concepts and an unambiguous notation are suggested as tools to reconcile disagreements.


The aim of the work is to design a robust hybrid active-passive magnetic field shielding system created by overhead power lines with a triangular arrangement of phase wires, designed to increase the shielding efficiency of the initial magnetic field in residential premises to the level of sanitary standards and reduce the system's sensitivity to changes in system parameters. To achieve this goal, the following tasks were solved: the structure of a hybrid system of active-passive shielding was developed, and the synthesis of a system consisting of a double-circuit active and multi-circuit passive parts was performed. The synthesis of the system is reduced to solving a vector game, in which the vector payoff is calculated based on the solutions of the Maxwell equations in the quasi-stationary approximation using the COMSOL Multiphysics software. The solution of a multicriteria game is found on the basis of algorithms for optimizing a multi-swarm of particles from Pareto optimal solutions, taking into account binary preference relations. The most important results are theoretical and experimental studies of the effectiveness of the synthesized hybrid active-passive shielding system for the magnetic field created by overhead power lines with a triangular arrangement of phase wires in the shielding zone. The significance of the results obtained lies in the fact that in the course of designing a hybrid active and multiloop passive screens, the parameters of passive and active screens were calculated; as well as practical recommendations are given on the reasonable choice of the spatial arrangement of a multi-loop passive shield and two shielding windings of a robust system of hybrid shielding of the magnetic field created by overhead power lines with a triangular arrangement of phase wires.


Using spin-resolved time-of-flight momentum microscopy, the Rashba splitting of the Tamm surface state is investigated. This state resides at the Fermi level in a projected bulk band gap of the close-packed (0001) surface of hcp Re. The Rashba splitting amounts to 0 . 4 Å − 1 . The state with smaller parallel momentum is fully separated from bulk states, whereas the Rashba branch with larger momentum hybridizes with bulk states, which leads to a suppression of spin-momentum locking. We find a good agreement of the experimental results with one step photoemission calculations that are based on ab initio theory within the local density approximation. The spin polarization of the inner Rashba state is not complete, which manifests in the occurrence of quantum interference patterns as observed by scanning tunneling microscopy. A one-to-one agreement of scanning tunneling spectroscopy and photoemission results is observed, suggesting that the quantum interference pattern originates from the inner Rashba state.


The two-dimensional O-ring seal nonlinear axisymmetric finite element model are established which is used for swinging hydraulic cylinder. Some factors influencing rubber O-ring sealing performance were taken into account, such as rotating shaft diameter, O-ring seal section diameter. The results indicate that when medium pressure is zero, the two factors influence Von Mises and maximum contact stress of sealing face greatly. Under medium pressure (P=10Mpa), the two factors have a little influence to Von Mises and maximum contact stress.


Ants can be important tools to assess the conditions of a given environment, as well as to monitor restoration of degraded areas. This study evaluated the richness and abundance of ant assemblages associated with areas directly impacted by the construction of small hydropower plants in the State of Paraná. To survey the ant fauna, samples were collected in September 2014 and January 2015 using pitfall and malaise traps. The association of the ant fauna composition with fragments and seasonality was analyzed by detrended correspondence. Fifty-eight species of ants were registered. The subfamily Myrmicine and the genus Camponotus were the most abundant (S= 25, S = 10, respectively). The removal of vegetation and formation of lakes in the directly affected area cause impacts that can be monitored based on the results of this study.


The physicochemical characteristics and sensory properties of Deodeok wine, formed by leaching of Deodeok at room temperature for 180 days, were investigated over the following range of Deodeok levels: 10, 15 and 20% (all w/v). The higher the level of Deodeok, the greater were the final values of total sugars, reducing sugars, total polyphenols, and crude saponins. The Hunter's b-value (yellowness) of Deodeok wine varied markedly with Deodeok levels, and yellowness was highest in Deodeok wine containing 20% (w/v) Deodeok. Non-volatile compounds, that form the basis of the liquor tax law, were 0.64, 1.38 and 2.11% (all w/v), respectively, at day 160. Of these values, that of 2.11% (w/v), the level of non-volatile compounds in Deodeok wine containing 20% (w/v) Deodeok, was in accord with the liquor tax law (that requires this figure to be 2.0%). Sensory evaluation showed that Deodeok wine containing 20% (w/v) Deodeok was superior to the other wines tested.


Soil nitrogen transformations and nitrous oxide flux across the soil-air interface were measured in a range of tropical forest sites in Costa Rica, Brazil, and Hawaii. Nitrogen mineralization and nitrification potentials were high in the relatively fertile Costa Rica sites and the Amazonian oxisol/ultisols (>1.5 μg g−1 d−1 of N mineralized), intermediate in Amazonian white sand soils (0.5-0.8 μg g−1 d−1) and low in the Hawaiian montane sites (<0.5 μg g−1 d−1). Nitrous oxide fluxes ranged from 0 to 6.2 ng cm−2 h−1 of N; mean flux per site was highly correlated with mean nitrogen mineralization across 26 sites. These correlated patterns of nitrogen cycling and trace gas production could be useful in the development of regional- and global-scale estimates of nitrous oxide fluxes from tropical forests.


Differences between longitudinal and transverse two-proton correlation functions, consistent with finite lifetime effects, are observed for central [sup 36]Ar+[sup 45]Sc collisions at [ital E]/[ital A]=80 MeV. The correlations between two protons emitted with low total momenta are consistent with emission from a source of Gaussian radius [ital r][sub 0][approx]4.7[plus minus]0.3 fm and characteristic lifetime [tau][approx]25[plus minus]15 fm/[ital c].


Millions of smart meters have been installed all around the world so far. The reported meter readings are conducive for utility companies to provide high quality of service. To efficiently and securely make use of those readings, data aggregation has been widely studied. Lu et al. proposed an Efficient and privacypreserving aggregation (EPPA) scheme for secure smart grid communications in recent years. Unfortunately, we found a man-in-the-middle attack to the EPPA scheme in this paper. We then propose a new meter reading aggregation scheme, namely Universally composable meter reading aggregation (UCMRA) scheme, in order to resist against that attack. Moreover, we give a universally composable symbolic analysis to prove the security for UCMRA scheme. This proof also enables the UCMRA scheme to adopt an alternative cryptographic primitive arbitrarily, as long as the primitive meets the requirements of the corresponding ideal functionality. Finally, the experiment results show that the performance of the UCMRA scheme is almost as good as that of the EPPA scheme.


Objective To investigate the factors influencing sleep quality in patients with coronary heart disease after percutaneous coronary intervention(PCI),and search for effective ways to improve sleep quality by nursing intervention.MethodsThis study consisted of 104 post-PCI patients who were evenly divided into experiment group and control group in random.Nursing intervention was given to the experiment group,and routine nursing to the control.Pittsburgh Sleep Quality Index(PSQI) questionnaire and a self-designed questionnaire were used for the study.Results The main factors influencing sleep quality were malaise,anxiety,environment,iatrogenic factors and living habit,the difference was not significant between the two groups(χ2=0.04-0.22,P0.05).Compared with the control group,the total PSQI score,subjective sleeping quality,hours and efficiency of sleep,sleep disorder,hypnotic drug and fraction of daytime performance were lower(t=3.987-38.722,P0.01),the complication rate was lower and hospital day shorter(χ2=2.66,P0.01),the satisfaction rate(96%) was higher(χ2=8.25,P0.01).Conclusion Active nursing intervention for post-PCI patients could improve their quality of sleep and promote their recovery.


Spoof surface plasmons (SSP) on the corrugated metal surfaces has attracted enormous attentions due to its many extraordinary properties and can find a variety of applications in microwave and terahertz (THz) community. In this paper, we present a theoretical and numerical study of SSP mode on the dielectric-loaded double-corrugated gratings. General SSP dispersion theory is developed by a simplified modal expansion method on the structure which is also verified in THz band. In our referred structure, symmetric SSP mode demonstrates lower propagation loss compared with the other anti-symmetric SSP mode. Our studies about SSP modes on the dielectric-loaded doubly corrugated grating can provide new ways to realize both extreme sub-wavelength confinement and low propagation loss. Potential applications include low loss waveguide and circuitry, sensitive sensing and novel electronic sources induced by injected electron beam, etc.


Although one function of the earliest university presses in North America — established over 130 years ago — was publication of the theses and dissertations of their host institutions' own students, fulfilling the widely held condition that doctoral work completed at US and Canadian institutions be published is now essentially handled by ProQuest Information and Learning (formerly University Microfilms International), which processes over 70,000 theses and dissertations each year. Graduate students at most US and Canadian institutions simply complete a form, perhaps pay a nominal processing fee, and submit —electronically —their departmentally and institutionally approved theses and dissertations to the company. Et voilà, the work is published! Why, then, the need for these two works on converting dissertations into publications, especially given the presence of such time-tested books on the topic by the likes of William Germano, Beth Luey, and others? In short, the issue of dissertation and thesis publication is more complicated: ProQuest is not ubiquitous; submitted works are not assigned ISBNs; copyright works in various ways; and many individuals and institutions do not consider the works really published in the first place, even if electronic copies may be downloaded or hard copies ordered. In that sense ProQuest is more a repository and duplicating service, akin to services provided by numerous


Organized by IBRA, this conference aims to bring together the international scientific community involved with bees, to broaden our understanding of bees and how they interact with the environment, and to encourage everyone to focus their specialization on the central theme of movement of bees. Such movement may be natural or involve man, but either way there are consequences for the bees, for their pests and predators, and for the environment. It is hoped that this new approach will help to break down the usual compartments and divisions, thereby giving a wider view of the effects of globalisation on all types of bees, their management and their exploitation.


During the 1982–1984 bradyseismic crises in the Campi Flegrei area (Italy), the University of Wisconsin deployed a network of seismological stations to record local earthquakes. In order to analyse the potential of the recorded data in terms of tomographic imaging, a blind test was recently set up and carried out in the framework of a research project. A model representing a hypothetical 3D structure of the area containing the Campi Flegrei caldera was also set up, and a synthetic dataset of time arrivals was in turn computed. The synthetic dataset consists of several thousand P- and S-time arrivals, computed at about fourteen stations. The tomographic inversion was performed by four independent teams using different methods. The teams had no knowledge of either the input velocity model or the earthquake hypocenters used to create the synthetic dataset. The results obtained by the different groups were compared and analysed in light of the true model.
This work provides a thorough analysis of the earthquake tomography potential of the dataset recording the seismic activity at Campi Flegrei in the 1982–1984 period. It shows that all the tested earthquake tomography methods provide reliable low-resolution images of the background velocity field of the Campi Flegrei area, but with some differences. However, none of them succeeds in detecting the hypothetical structure details (i.e. with a size smaller than about 1.5–2 km), such as a magmatic chamber 4 km deep and especially the smaller, isolated bodies, which represent possible magmatic chimneys and intrusions.

Alignment techniques for calamitic liquid crystals are well developed and play a crucial role in liquid crystal devices. Comparatively little attention has been paid to the alignment of discotic liquid crystals. Only recently the integration of discotic liquid crystals into optical and electronic devices stimulated the development of new alignment techniques for discotic nematic and columnar mesophases. This mini-review attempts a brief summary of the challenges and recent success stories. Two new approaches to the alignment of discotic columnar mesophases will also be presented.


The energy conditions play an important role in the understanding of several properties of the Universe, including the current accelerating expansion phase and the possible existence of the so-called phantom fields. We show that the integrated bounds provided by the energy conditions on cosmological observables such as the distance modulus {mu}(z) and the lookback time t{sub L}(z) are not sufficient (or necessary) to ensure the local fulfillment of the energy conditions, making explicit the limitation of these bounds in the confrontation with observational data. We recast the energy conditions as bounds on the deceleration and normalized Hubble parameters, obtaining new bounds which are necessary and sufficient for the local fulfillment of the energy conditions. A statistical confrontation, with 1{sigma}-3{sigma} confidence levels, between our bounds and supernovae data from the gold and combined samples is made for the recent past. Our analyses indicate, with 3{sigma} confidence levels, the fulfillment of both the weak energy condition (WEC) and dominant energy condition (DEC) for z{<=}1 and z < or approx. 0.8, respectively. In addition, they suggest a possible recent violation of the null energy condition (NEC) with 3{sigma}, i.e. a very recent phase of superacceleration. Our analyses also show the possibility of violationmore » of the strong energy condition (SEC) with 3{sigma} in the recent past (z{<=}1), but interestingly the q(z)-best-fit curve crosses the SEC--fulfillment divider at z{approx_equal}0.67, which is a value very close to the beginning of the epoch of cosmic acceleration predicted by the standard concordance flat {lambda}CDM scenario.« less


We address the challenging problem of the joint estimation of transmitted symbols and phase distortions in standardized multicarrier systems, including pilot or virtual subcarriers. These subcarriers create time correlation on the useful transmitted OFDM signal that we propose to take into account by an autoregressive model. Because the phase distortions are nonlinear, we set the joint estimation algorithm on the framework of the Sequential Monte Carlo methods. Simulation results are provided in terms of bit error rate (BER) and mean square error (MSE); they highlight the efficiency and the robustness of the estimator.


ABSTRACT Pregnant Wistar rats were given orally enalapril maleate (EM), an angiotensin‐converting enzyme (ACE) inhibitor, 15–60 min prior to Caesarean operation and the diameter of the ductus arteriosus (DA) in the newborn rats was calibrated at intervals after delivery. The caliber of the DA in control newborn rats gradually decreased to less than 10% of the initial value by 90 rnin after delivery. The DA calibers of the newborn rats treated with 50 or 200 mg/kg EM in utero were larger than the controls at any time interval up to 90 rnin and the difference from the control value was significant for at least 30 rnin after delivery when the drug was given to the dam 30 rnin prior to Caesarean section. The present study has demonstrated that transplacentally‐administered enalapril inhibits the spontaneous constriction of the neonatal rat DA and supports the view that ACE inhibitors should not be used late in pregnancy.


Biliary neoplasms are uncommon in cats and affect older animals. A 12-year-old female crossbreed cat showed prostration, lethargy, apathy, and severe jaundice. Ultrasonography showed distention of the gallbladder associated with severe obstruction of the bile ducts with thickening of the biliary wall, forming amorphous masses of irregular contour and heterogeneous appearance directed to the lumen measuring up to 2 cm. Necropsy showed a gallbladder with a yellowish and soft nodule measuring 3 × 3 cm, compressing the extrahepatic bile duct, occluding the passage of bile. There were also firm, yellowish multifocal to coalescing nodules in the liver, ranging from 0.5 to 1 cm, affecting 10% of the organ, in addition to lungs with firm, yellowish multifocal nodules ranging from 0.2 to 0.5 cm, affecting 20% of the organ. Histologically, gallbladder and bile ducts had malignant epithelial neoplastic proliferation, which was organized into multiple papillary and ductal projections, separated by moderate fibrovascular stroma compatible with gallbladder adenocarcinoma. The liver and lungs also contained neoplastic structures with a ductal appearance and papilliform projections identical to those observed in the gallbladder. The immunohistochemical examination (IHC) showed intense positive staining of epithelial neoplastic cells for pan-cytokeratin (AE1/AE3) and no staining for vimentin (Clone V9). The diagnosis of gallbladder adenocarcinoma with metastasis in the liver and lungs was established based on the clinical, macroscopic, histopathological, and immunohistochemical findings.


In this paper, a tri-band miniaturized wide-angle and polarization-insensitive metasurface is proposed as an ambient energy collector. The metasurface is composed of a subwavelength butterfly-type closed-ring (BCR) array attached to a low-loss substrate with a metallic ground. Each unit cell of the energy harvesting metasurface has only one harvesting port. Its energy harvesting efficiency for different polarization and incident angles was analyzed, and the results show that the maximum harvesting efficiency is 90%, 83%, and 81% at the three frequency bands of 0.9 GHz, 2.6 GHz, and 5.7 GHz, respectively. Moreover, a prototype of the 7 × 7 BCR metasurface harvesting array was fabricated and measured. The experimental results validate that the proposed metasurface performs well under transverse electric and transverse magnetic polarization and is suitable for wide-angle incident energy harvesting in the three frequency bands.


Abstract : Flights in the coverage area of Segment 3 of the East Coast OTH-B radar to calibrate a radar target emulator were used to study propagation conditions over long paths (> 3000 km) off the East Coast of the U.S. Analysis of MOF data, derived from oblique propagation ionograms, and MUF data derived for respective distances from the onboard ionosonde data indicate substantial discrepancies. This is, in view of the long path, not surprising. MOF changes were out of phase with path length changes. The analysis of Martyn's Theorem shows, that for the long propagation path, the contribution of MUF variation from the time dependence of foF2 was 22 times greater than the range contribution, and of the opposite sign, under the conditions observed during the measurement.


The COVID-19 pandemic generates many uncertainties for everyone, but for Asia's poor and marginalized, there is little doubt about the devastating consequences. It's not only about unequal access to public health care, but also the loss of livelihoods that wreaks havoc in disadvantaged communities living on the edge of subsistence that are more l ikely to experience police abuses under the pretext of lockdown and quarantine enforcement. As second and third waves strike, the menace of this coronavirus and the high risk of letting our guard down becomes all the more evident. Resurgences of cases in Australia, Hong Kong, and Japan provide stark reminders that turning the corner does not mean being out of harm's way. Much debate focuses on the trade-off between public health and jobs as various degrees of lockdowns boost unemployment, especially for contingent workers. Moreover, the contagion of fear and anxieties about the future, along with travel restrictions and closed schools, keep people at home and purse strings tight, forcing many businesses to close in a downward spiral of contraction and dislocation. Despite governments around the region rolling out various countermeasures to soften the economic pain, including massive stimulus packages, these schemes are but a band-aid. Even relatively prosperous nations remain vulnerable to the gathering economic typhoon, because the pandemic is a transnational catastrophe that is disrupting markets and supply-chains while battering down growth rates and demand.


Recently, system theorists have recognized that low order systems of nonlinear differential equations can give rise to solutions which are neither periodic, constant, nor predictable in steady state, but which are nonetheless bounded and deterministic. This behavior, which was first described in the study of weather systems, has been termed 'chaotic.' Much study of chaotic systems has concentrated on analysis of the systems' phase space attractors. It has been recognized that invariant measures of the attractor possess inherent information about the system. One such measure is the dimension of the attractors. The dimension of a chaotic attractor has been shown to be noninteger, leading to the term 'strange attractor;' the attractor is said to have a fractal structure. The correlation dimension has become one of the most popular measures of dimension. However, many problems have been identified in correlation dimension estimation from time sequences. The most common methods for obtaining the correlation dimension have been least squares curves fitting to find the slope of the correlation integral and the Takens Estimator. However, these estimates show unacceptable sensitivity to the upper limit on the distance chosen. Here, a new method is proposed which is shown to be rather insensitive to the upper limit and to perform in a very stable manner, at least in the absence of noise. The correlation dimension is also shown to be an effective discriminant in distinguishing between radar returns resulting from weather and those from the ground. The weather returns are shown to have a correlation dimension generally between 2.0 and 3.0, while ground returns have a correlation dimension exceeding 3.0.


Formwork is the use of support structures and moulds to create structures out of concrete which is poured into the moulds. There are many different types of formwork used in construction, usually differing according to what the building requirements and challenges are in construction. Formwork is used by creating moulds out of wood, steel, aluminum or prefabricated forms into which the concrete is poured. This is then allowed to harden and set after which it is stripped, or in the case of stay-in-place formwork it is left as part of the structure. Formwork allows contractors to cast and construct the main parts of a building which are required to be strong and support the structure such as floors and walls, as well as smaller parts of a building such as stairs relatively quickly. Now in modern era consumer is using or choosing formwork based upon the maximum possible uses, initial and maintenance cost, erection and dismantling time, suitability of labour. In this research work, Factors for selecting and applicability criteria have been decided from the various literatures and the interview with the selected respondents. Questionnaire has been prepared with keep in mind about residential projects and commercial projects only and prepared different questionnaires for different respondents in the different language too. Questionnaire will be distributed to various consultant, Contractor and manufacturer/distributor of formwork in various parts of south Gujarat Region.


Rocket-based combined-cycle (RBCC) vehicles have the potential to reduce launch costs through the use of several different air breathing engine cycles, which reduce fuel consumption. The rocket-ejector cycle, in which air is entrained into an ejector section by the rocket exhaust, is used at flight speeds below Mach 2. This thesis develops a design method for an air intake geometry around a novel RBCC rocket nozzle design for the rocket-ejector engine cycle. This design method consists of a geometry creation step in which a three-dimensional intake geometry is generated, and a simple flow analysis step which predicts the air intake mass flow rate. The air intake geometry is created using the rocket nozzle geometry and eight primary input parameters. The input parameters are selected to give the user significant control over the air intake shape. The flow analysis step uses an inviscid panel method and an integral boundary layer method to estimate the air mass flow rate through the intake geometry. Intake mass flow rate is used as a performance metric since it directly affects the amount of thrust a rocket-ejector can produce. The design method results for the air intake operating at several different points along the subsonic portion of the Ariane 4 flight profile are found to under predict mass flow rate by up to 8.6% when compared to three-dimensional computational fluid dynamics simulations for the same air intake.


Direct sequence spread spectrum code phase acquisition schemes have been proposed which use cyclic accumulation and a matched filter to provide a rapid estimate of the correct code phase. Transition probabilities have been evaluated by using computer simulation and mean acquisition times were determined using a system model. Comparisons of mean acquisition time for six schemes have made. Results indicate that the proposed schemes will achieve much better acquisition time performance than previously reported methods.


EnglishDr Svatikova and colleagues1 investigated acute cardiovascular responses in healthy adults 30 minutes after ingestion of an energy drink (containing 62 g of sugar, caffeine, and taurine) compared with a placebo drink (containing approximately 62 g of sugar but no caffeine or other stimulants). In addition, the authors investigated the cardiovascular response of energy drink consumption during mental and physical stress tests. EnglishDr Grasser and colleagues discuss the importance of longer postdrink blood pressure and heart rate observation periods and suggest that water would have been a more appropriate placebo drink. First, with regard to duration of observation, our protocol was designed to follow closely the metabolism and bioavailability of caffeine. Oral absorption of caffeine from the intestinal tract is rapid and caffeine becomes completely bioavailable, reaching a peak plasma concentration 30 minutes after ingestion, whereas plasma half-life ranges from 3 to 10 hours.1


AbstractTime series of global and regional mean surface air temperature (SAT) anomalies are a common metric used to estimate recent climate change. Various techniques can be used to create these time series from meteorological station data. The degree of difference arising from using five different techniques, based on existing temperature anomaly dataset techniques, to estimate Arctic SAT anomalies over land and sea ice was investigated using reanalysis data as a test bed. Techniques that interpolated anomalies were found to result in smaller errors than noninterpolating techniques relative to the reanalysis reference. Kriging techniques provided the smallest errors in estimates of Arctic anomalies, and simple kriging was often the best kriging method in this study, especially over sea ice. A linear interpolation technique had, on average, root-mean-square errors (RMSEs) up to 0.55 K larger than the two kriging techniques tested. Noninterpolating techniques provided the least representative anomaly estim...


Proteomics is a comprehensive study of proteins that focuses on their structure and function. After genomics, proteomics considered the next step for the study of biological systems. But it is much more complicated than the study of genomics, because the genome of an organism is more or less constant, while the proteome differs in different cells depending on weather and other factors that influence it. This science is of great interest in the fields of human and veterinary medicine. In our study, we were using the method of proteomics to see the quantity and the expression of proteins in the serum of sheep in the normal (physiological) status. The tests were conducted in Mass spectrometry Laboratory–GIGA - Proteomics, University of Liege, Belgium during November 2011. After the preparation of the samples in the laboratory, a differential proteomic study using a label-free LC-MSe method was conducted (nano-2D UPLC coupled to a Synapt TM HDMS TM MSe, Waters, Figure 1). The aim of this study is to create data regarding the number, name, size and the role of different proteins found in blood serum of sheep. These data will serve as a reference to compare the results that will be taken from the analysis of serum to be made to the application of various proteomics study in infected animals or in the study of response to immunizations by different vaccines in their prophylaxis program. In our samples, we identified 47, 45 and 49 proteins in Sheep NCBI database in comparison with 114, 105 and 128 numbers of proteins identified respectively in each sample pool from the reviewed mammalian database. These results need of course to be further investigated in different stress agents like biological (infection diseases), physical and chemical agents etc. Keywords: Protein, proteomics, sheep, Mass Spectrometry.


In recent years, there has been a growing interest in the study of sparse representation. Sparse representation has been adopted in this paper for automatic target detection in hyperspectral image(HSI). We using a novel algorithm, the K-SVD, designing overcomplete dictionaries for sparse representation. The sparse representation is recovered by solving a greedy algorithm called Orthogonal Matching Pursuit (OMP) and it directly determines the class label of the test sample. As the neighboring HIS pixels usually have similar spectral characteristics and usually belongs to the same class, we use the smoothing of HIS pixels to constraint on sparsity and improve the reconstruction accuracy. The simulation results of this study demonstrated that it is effective.


Innovative entrepreneurship education has achieved gratifying achievements since it was firstly put forward by Tsinghua University. However, how to objectively evaluate the quality of innovative entrepreneurship education in different levels universities has not yet formed a unified standard and general evaluation system, the paper put forward a new quality evaluation system for innovative entrepreneurship education. The paper buildes the innovative entrepreneurship education quality evaluation system composed of 4 first-level indicators, 10 second-level indicators and 26 third-level indicators, which provides a methodological reference for the quality evaluation, the direction of innovative talent training mode and teaching reform, a subsystem to evaluate the running level of local colleges.


The post-positivist view on policy analysis – i.e. that policy change is not so much the result of the development of problems that can be determined objectively, but that these problems are constructed largely in policy narratives and frames – has by now become part of mainstream policy analysis. However, the exact relationship between frames, storylines, problems, data use, values, opinions and assumptions is not always crystal clear. Systematic analyses of this topic are hard to find in literature. One of the few exceptions is the work of Brandwein (2006). She separates values, opinions and assumptions within an interpretive frame from the interpretive products such as storylines and problematizations. This paper adds the selection and interpretation of data to her list of interpretive products and consequently examines the analytical potential of this extended version of Brandwein's model as it is used for the analysis of female labor market participation policy in Dutch women emancipation memorandums. http://www.boomlemmatijdschriften.nl/tijd-schrift/benm/detail

This paper summarizes the calculations performed at Sandia National Laboratories using the COMPBRN fire model for the Heiss Dampf Reaktor (HDR) tests E41.7 and E42.2. A Sandia modified version of COMPBRN III was used for the calculations. Test E41.7 was on oil pool fire, and test E42.2 was cable fire. Both tests were conducted inside a small room within the HDR containment. Calculations were also performed for test E41.7 with the Notre Dame Fire Model. Hot gas layer temperatures and other relevant results are presented. Comparison with experimental data is made, where possible. A brief discussion on the problems encountered in the application of fire models to nuclear power plant fire modeling is also included.


The emerging meta- and multi-verse landscape is yet another step towards the more prevalent use of already ubiquitous online markets. In such markets, recommender systems play critical roles by offering items of interest to the users, thereby narrowing down a vast search space that comprises hundreds of thousands of products. Recommender systems are usually designed to learn common user behaviors and rely on them for inference. This approach, while effective, is oblivious to subtle idiosyncrasies that differentiate humans from each other. Focusing on this observation, we propose an architecture that relies on common patterns as well as individual behaviors to tailor its recommendations for each person. Simulations under a controlled environment show that our proposed model learns interpretable personalized user behaviors. Our empirical results on Nielsen Consumer Panel dataset indicate that the proposed approach achieves up to 27.9% performance improvement compared to the state-of-the-art.


Let F, G and H be graphs. Notation F → (G, H) means that there is any two-coloring, say red and blue, of all edges of F which contains red subgraph isomorphic to G or blue subgraph isomorphic to H. The graph F is Ramsey (G, H)-minimal graph if F → (G, H) but F − e ↛ (G, H) for any e ∈ E(F). The class of all Ramsey (G, H)-minimal graphs will be denoted by R(G, H). In this paper, we proved that there are only two graphs with six vertices that belong to Ramsey minimal graphs for certain pair of path and cycle (P 3, C 6) and we also determined some graphs with eight vertices in R(P 3, C 6).


Accurate coefficient of permeability is of vital importance for the underground water computing. In the paper, the coefficient of permeability is identified based on the observed hydraulic heads and drainages. An optimization model is used to identify the coefficient of permeability, which is solved with genetic algorithm. The performances of the proposed identification measure with improved genetic algorithm is testified by actual engineering applications and the results show that the parameter identification algorithm proposed in the paper is robust and globally convergent.


A wideband ac magnetic field sensor using the nonlinear magnetoelectric effect of magnetic fields mixing in a planar structure consisting of a piezoelectric langatate and an amorphous ferromagnet has been described. The measured and pumping fields mix due to nonlinearity of the ferromagnetic layer magnetostriction. The voltage of the total frequency generated by the langatate layer is recorded at the frequency of the structure planar acoustic oscillations that provide both frequency selectivity and enhancement of the voltage by Q ≈ 1400. The maximum sensitivity of the sensor is 1.8 V/Oe, which is ~320 times higher than the sensitivity of the sensor using the linear magnetoelectric effect, but ~4 times lower than the sensitivity of the linear sensor at the resonance. The sensor operates without a dc bias magnetic field and allows registration of fields as low as ~10-5 Oe in the frequency band of 1-70 kHz with a frequency resolution of ~50 Hz.


A Signal of Interest (SOI) is a signal the operator has decided to record for further analysis. This is driven by mission requirements, known anomaly characteristics, or unidentifiable signals. Currently on our radar detection system, identifying SOI or anomalies is reliant on the system operator's knowledge and skill, a method highly susceptible to human error. The objective was to find a way to provide the system operator with improved awareness by automating identifying SOIs or anomalies with machine learning and artificial intelligence techniques. By applying data science processes and techniques such as density-based clustering algorithms and artificial neural networks to our data, we successfully proved the daily emitter and frequency distribution in the Hampton Roads area has a strong consistent subset of emitter traffic, identified anomalies based on this fingerprint, and implemented this algorithm in an application which provides a graphic that highlights anomalies and SOIs.


The Spitzer Science Center (SSC) and the National Optical Astronomy Observatory (NOAO) have designed a program for teacher and student research using observing time on the Spitzer Space Telescope. (For more information on this program, please see our companion poster, Rebull et al.) As part of this program, we are developing a wiki, where the scientists, teachers, and students can share the materials they have developed and interact with each other. The wiki currently has background information, some general lessons and discussion pages; it also provides a place for the teams to continue working on their specific research projects. This poster will describe some of the wiki contents, and our plans for future development.

The T-Tauri Candidate intensity value is compared to the average intensity value of the non-T-Tauri Candidates in the field, and using Microsoft Excel students plot light curves with this data. The plots can then be shared with other students via the Wiki. --NicholasJamesKelley 10:17, 11 December 2007 (PST)This area will be used to show the current progress I am making toward proving that Candidates 415 and 416 are T-Tauri Stars. --NicholasJamesKelley 10:47, 7 December 2007 (PST) These are my light curves for the 2 candidates that I am monitoring for Spitzer and the Pittsburgh Science fair. I am currently monitoring to get more accurate curves to take with me. Students Sharing NEW Data Analysis Techniques Two things we believe to be true about YSO's or T-Tauri candidates is that they should have an excess of dust around the star, and the star itself should be active. The excess of dust around the object would be indicated by a higher than normal emission in the infrared, and highly active stars give off a strong H-alpha emission. Unfortunately high schools rarely have access to the sort of high end equipment necessary for spectral analysis of stars, however more and more lower end internet accessible telescopes are coming online. We believe we have identified a technique that can be used with relative ease to identify stars with both infrared excess and H-alpha emissions. Identification of Infrared Excess – Image YSO targets in both R and I. Using MaxIm DL or some other image analysis software with photometric capabilities measure intensity of all objects in the image. Determine the I/R intensity ratio for each object. On a color color plot (see below), objects with significant dust should break away from those stars with normal black body curves. Identification of H-alpha Emission – Image YSO targets using both a broadband R filter and a narrow band H-alpha filter. Since the H-alpha filter is a narrow part of the broadband R filter (see figure below), an H-alpha/R intensity ratio can be used to determine stars with an H-alpha emission line. Objects with significant H-alpha emissions should break away from those stars with normal emissions. Presenting the Research Process to High School Students—One Project Young Stars in IC 2118 We are studying Interstellar Cloud 2118, or the Witch Head Nebula. It is being excited by a young, hot star called Rigel, which is so energetic it releases shock waves that compress the gas, which clumps, attracting more matter, until it eventually accumulates the critical mass needed to form a star. We think this particular nebula is forming lots of stars; in fact, we call it a cocoon, a nursery, or a natal cloud. We have to identify the objects as actual newborn stars, however, and therein lies the problem. How do you know a newborn star when you see one? Does it look different from a middle-aged star? How can you tell if it's in your cloud, and not in front of it, or that it's not a distant galaxy? You can't perceive depth in space; everything is so far away that every object looks like a point source, a tiny dot of light. And it could be a certain magnitude (brightness) because it is really far away but very bright, or not so bright but very close. A real dilemma! Research scientists (and research students and teachers!) have all these questions, and start figuring out ways to answer them. In the case of astronomy, the only phenomenon we have to observe and measure is the light that comes from the object. The distances are so far that we can't travel to see the objects or bring back samples, so we use the only thing they can send us: their light. Astronomers have gotten very good at observing, measuring, and analyzing light from great distances. Characteristics of Young Stars: how do you tell which of these point sources of light is a young star? Young stars have unique characteristics. Like their young, human counterparts, they are lively, hyperactive, and change quickly as youngsters. The graphic above details most of these. We look for : •Infrared excess •Spatial location •Flaring X-rays •Spatial motion •Emission lines •Similar brightness •Fast rotation rate •Variability of light produced by UV emission, starspots, and outflows of ejected gas The Search for Young Star Candidates You are a district attorney trying to make the case that these point sources in IC2118 are T-Tauri stars. You must convince the jury (your colleagues) that these are, indeed, stars tucked away in their IC2118 nursery. Like any good prosecutor, you need a preponderance of the evidence: How many of the characteristics listed above for young stars can you "pin" on a candidate? Is it enough to "convict"? Some characteristics can only be seen by chance—you have to catch the star in the act, so to speak. Your surveillance begins: observing the stars in as many wavelengths and epochs as you can, and analyzing the evidence. Background info on Infrared Astronomy Background info on Spitzer Space Telescope Background info on Specific Topics : PAHS The Wiki has a section that provides background information for students and teachers. As new students join the research process, they can be directed to the Wiki for background reading and information. Students can post questions and discuss information with each other. They can follow instructions on how to download Spitzer images from Leopard, and how to make tri-color images. Independent students should be able to follow directions without much teacher intervention. Background, Research Tools and Instructions


In order to match the voltages between high voltage battery stacks and low voltage super-capacitors with a high conversion efficiency in hybrid energy sources electric vehicles (HESEVs), a high ratio bidirectional DC-DC converter with a synchronous rectification H-Bridge is proposed in this paper. The principles of high ratio step down and step-up operations are analyzed. In terms of the bidirectional characteristic of the H-Bridge, the bidirectional synchronous rectification (SR) operation is presented without any extra hardware. Then the SR power switches can achieve zero voltage switching (ZVS) turn-on and turn-off during dead time, and the power conversion efficiency is improved compared to that of the diode rectification (DR) operation, as well as the utilization of power switches. Experimental results show that the proposed converter can operate bidirectionally in the wide ratio range of 3~10, when the low voltage continuously varies between 15V and 50V. The maximum efficiencies are 94.1% in the Buck mode, and 93.6% in the Boost mode. In addition, the corresponding largest efficiency variations between SR and DR operations are 4.8% and 3.4%. This converter is suitable for use as a power interface between the battery stacks and super-capacitors in HESEVs.


Some numerical methods are presented for back-analysis of the earth pressure against the retaining pile for deep excavation by making use of the measured bending moments. The calculating results for one excavation case show that the distribution and value of the earth pressure above the excavation bottom on the retaining piles airs quite different from the classical Coulomb's or Rankine's earth pressure theory. The nonlinear distribution of earth pressure can be explained by means of soil arching theory. An earth pressure model is proposed.


#### The bottom line

The care that a woman receives during labour has the potential to affect the woman herself, both physically and emotionally, and the health of her baby in the short and longer term. Good communication, support, and compassion from staff, as well as having her wishes respected, can help her feel in control of what is happening and help make birth a positive experience for the woman and her birth companion(s).

About 700 000 women give birth in England and Wales each year. Most are healthy, have a straightforward pregnancy, go into labour spontaneously, and give birth to a single baby after 37 weeks of pregnancy. Uncertainty around consistent practice and the availability of new evidence necessitated an update of 2007 guidance from the National Institute for Health and Care Excellence (NICE) on intrapartum care.1 This article summarises the most recent recommendations from NICE on the care of healthy women who go into labour at term (37-41 weeks' gestation) (Clinical Guideline CG190).2

NICE recommendations are based on systematic reviews of the best available evidence and explicit consideration of cost effectiveness. When minimal evidence is available, recommendations are based on the Guideline Development Group's experience and opinion of what constitutes good practice. Evidence levels for the recommendations are given in italic in square brackets.

Rice planthopper is one of the causes for the great reduction of the yield of rice in Hubei Province.It is a kind of typical climatical moved flying insect pest,its takeoff,flying and settlement are closely related to weather conditions.In this article,the upper-air meteorological field data,and the rice planthopper monitoring data under the lamp,are used to analyze the example,using particle track and diffusion and settlement pattern HYSPLIT-4, etc.for exploring the fly path and main source of rice planthopper in Hubei Province.The main conclusions may be drawn as follows:(1) There are five paths of rice planthopper having moved in Hubei Province,i.e.the southwest path,the south path,the southeast path,the east path and the northeast path.(2) In spring and summer, the southwest path is the main path,with its proportion of 47%,followed by the south path and the southeast path.(3) In autumn,the northeast path is the main path,with its proportion of 30%,followed by the southwest path,being 23%of the total number.(4) In comparison with spring and summer,in autumn the proportion of southwest path is decreased by 24%,that of northeast path is increased by 22%,that of the east path is increased by 8%,and very few changes in the south path and southeast path.(5) The proportion of the southly path(the sum of the southwest path,the south path and the southeast path) is 80%in spring and summer,and that is 55%in autumn. Compared with spring and summer,autumn has a decrease of 25%.(6) No matter whether it is spring and summer,or autumn,the southwest path is the most impact on Hubei Province,and influence on the southern part is greater than the northern part.The influence of the northeast path in autumn is greater than that in spring and summer. The impacts of south path and southeast path on the Jianghan Plain are greater than the others.(7) In theory, the source area of rice planthopper is 19°—25°N,90°—120°E,with an east-west long axis and a north-south short axis, a rectangular area of approximately 3300 km×660 km Countries Vietnam,Thailand,Myanmar,Cambodia,and Philippines are the initial sources of rice planthopper,and regions Yunnan,Guizhou,Guangdong,Guangxi,Fujian, Hunan,Jiangxi,etc.,are the secondary sources or the third-class insect sources.Combining the forward trajectory simulation by numerical prediction field and the comprehensive analysis of insect source and target areas,we can carrry out the planthopper moving weather forecasting,and this work still needs further developing in operational tests.


Abstract The current study examined the effectiveness of the Self-Regulated Strategy Development (SRSD) model on the argumentative writing performance of EFL prospective teachers. Thirty third-year English prospective teachers in Port-Said University participated in this study using the pretest-posttest control group design. Students were randomly assigned to an experimental group (N = 14) and a control group (N = 16). The students were taught to apply the SRSD model as a strategy for planning and writing argumentative essays and to self-regulate their use of the strategy and the writing process. Results revealed improvements in the quality of argumentative essays in three areas (content, organization, and argumentation) of all 14 students. Changes in the students' writing performance were maintained over time and generalized to untrained writing genre. 1. Introduction Being able to articulate one's thoughts through written communication is central to being literate and to effectively function in society (Sylvester, 2007, p. 2). Well planned and effectively organized writing is an important part of the skills necessary for success both in academic study and employment. Teaching students strategies for crafting written products is necessary for expanding their skills to a level of competency necessary for passing required assessments, communicating curricular knowledge, advancing to college, gaining meaningful employment, and promotion or advancement in the workplace (Sundeen, 2007, p. 164). Education seeks to cultivate dispositions and skills that promote effective participation in democratic institutions, including the capacity to produce written arguments about controversial issues (Ferretti, Andrews-Weckerly, & Lewis,


86 students to help them manage stress better and inform their clinical recommendations to clients once they enter professional practice. Further controlled studies with long‐term follow‐up are now required to compare online and face‐to‐face education, document the specific mental, psychological, emotional, and physical benefits of yoga education, and determine the applicability of online yoga education to a broader spectrum of students.


For more than forty years, the United States Department of Agriculture Supplemental Nutrition Assistance Program (SNAP; formerly Food Stamps) has offered nutrition assistance to nearly forty million eligible individuals and families each month. This article first provides a brief overview of the evolution of the United States' largest domestic food security and nutrition safety net program. Then, the article reviews Congressional actions taken regarding SNAP during the 2018 Farm Bill deliberations, appropriations for fiscal years 2017 through 2020, and oversight (in)activities. The article focuses on Congressional activities regarding block grants; participant eligibility; benefit adequacy, issuance, and redemption; and strengthening SNAP's nutritional impacts. Next, the article discusses a variety of executive orders, administrative actions, initiatives, nominations, budget proposals, and tweets with SNAP implications put forth thus far by President Donald Trump, the 45th President of the United States. These actions include the America's Harvest Box, natural disaster responses, the public charge rule, tariffs on Chinese imports, and various agency relocations and reorganizations. The article reflects on how each of these legislative and executive developments might impact SNAP's organization, operations at the federal, tribal, state and retailer levels, and, ultimately, eating patterns and health of participating and eligible children and families, persons with disabilities, and elders.


Neonatal sepsis remains a leading cause of neonatal morbidity and mortality in infant, especially preterm and low birth weight baby. Sepsis is a clinical manifestation of a dysregulated immune response to invasive pathogen.There is increasing evidence that Toll-like receptors (TLRs) play a key role in the mediation of systemic responses to invading pathogens during sepsis. TLRs are essential for triggering the host's immune response, acting as a sensor against invading pathogens. TLR2 was identified as a receptor for gram-positive peptidoglycan and bacterial lipopeptides, whereas TLR4 is part of a receptor complex recognizing gram- negative bacterial. Saliva is an important body fluid for detecting the physiological and pathological situations of the human body. Neutrophils are considered to participate in the acute response against pathogens in many tissues, and influx into the oral cavity occurs at any time. The expression and function of TLRs greatly influence the quality and control of innate immune response in patients with infectious disease. The high expression of TLRs and phagocytic activity of neutrophil saliva upon presentation of early onset neonatal sepsis patients, suggests


An asymmetric total synthesis of (+)-coronafacic acid, starting from (R)-(+)-4-acetoxy-2-cyclopen-1-one as a chiral source, was accomplished. Construction of the 1-hydrindanone framework was carried out by using intramolecular 1, 6-conjugate addition as the key step. Coupling between (+)-coronafacic acid and protected coronamic acid, and subsequent deprotection provided (+)- coronatine. This is the first asymmetric total synthesis of (+)- coronatine.

Applications in molecular and atomic spectroscopy are also discussed


Objective To discuss the incidence,clinicopathologic features,treatment and prognosis of primary adenosquamous carcinoma of the stomach( PACS). Methods Clinical manifestation immunophenotype and pathological features of two cases of PACS were analyzed and relevant literatures were reviewed. Results Of the two cases,one was an 83-year-old male and the other was a 59-year-old female. The lesions were located at greater curvature side of gastric corpus or lesser curvature side of gastric antrum. The histology assumed that the neoplasms consisted of adenocarcinoma and squamous cell carcinoma. It was surrounded with gastric mucosa. Immunophenotype: Central cells of cell nests were expressed as CKhmw and peripheral cells as KClmw but NSE,CgA,and Synor were not expressed. Conclusion PACS is a rare malignant neoplasm with a male predominance. Most of the lesions were on the gastric antrum,the gastric body,the gastric antrum and body,and gastric fundus.It is an aggressive malignancy with poor prognosis.


Stock market is well known to all. It is an option for investment and trading. But it is a really difficult thing to predict the future stock price. It is helpful for the investors and traders to know the future price, so that they can enter and exit the market at the right time and right price. Although there are different methods to predict future price, new algorithms and deep learning performed quite well in this. In this paper Long Short Term Memory (LSTM) is used to predict stock price and here we studied the implications of epochs and batch size in the model.


ability withdraws the insane and mentally defective, the blind, the crippled, and other chronic invalids from productive activity, and its economic effect is frequently increased by the costs of institutional care. Among the aged, invalidity aggravates the economic difficulties of a group whose independence is already declining. The most serious social and economic consequences follow premature death of adults in their productive years. Loss of the mother endangers the health and welfare of children; loss of the wage earner subjects the entire family to economic disorganization. In the lower income groups, the disorganization caused by premature death or permanent disability is extreme, and readily observed. Public or voluntary agencies intervene to ameliorate its effects, providing aid for dependent children, the blind, the crippled child, and relief for the unemployable worker and his dependents. Governmental funds subsidize vocational rehabilitation of the handicapped. Industry compensates the worker permanently disabled by injuries incurred in the workplace. Governmental institutions largely supported by taxes provide care for the mentally diseased and defective.
