Highly Dense and Nanograined NiMn2O4 Negative Temperature coefficient Thermistor Thick Films Fabricated by Aerosol‐Deposition

Highly dense, negative temperature coefficient (NTC) thermistor thick films of NiMn2O4 were fabricated on glass substrate by aerosol deposition at room temperature. The nanocrystalline films thus obtained showed superior NTC figure characteristics with a B constant of over 3900 K without heat treatment. With increasing annealing temperature, the film resistivity was gradually decreased due to crystallization and grain growth, but the B constant was maintained over 3500 K.
Testing the 2*2 model of perfectionism in Iranian sample

Background and objective: The 2*2 model is the newest model of perfectionism that has been raised several hypotheses about the compatibility’s level of different types of perfectionism. The main aim of this study is testing these hypotheses. Methods: 891 MA student of Allameh Tabatabaee university of Tehran selected through cluster random sampling and divided into four groups based on perfectionism’s types with Hill perfectionism as a screening test. Then, these four groups were compared using multivariate analysis of variance (MANOVA) in terms of the components of general health to test the 2*2 model hypotheses. Results: Hypothesis8c and hypothesis 4 of 2*2 model of perfectionism are accepted. But hypothesis 2 and hypothesis 3 are not accepted because the results of this research show that the mixed perfectionism is more maladaptive than other combinations of ECP and PSP.
NUTRITIONAL STUDIES ON THE UTILIZATION OF VETIVER PLANTS (VETIVERIA ZIZANIOIDES L.) AS A NON -CONVENTIONAL FEED-STUFF FOR FEEDING SMALL RUMINANTS

The present study was conducted to estimate the nutritive value of vetiver plants (Vetiveria zizanioides L.) with different levels of concentrates (30, 50 and 70% of DM) compared to clover hay. In vitro dry matter disappearance (IVDMD) and organic matter disappearance (IVOMD) were determined. Vetiver grass was planted at Middle Sinai research station (El-Maghara) and produced 2.14 ton/feddan. The chemical composition showed that Vetiver grass had 10, 24.6 and 3.2 % as crude protein, crude fiber and lipids contents. Metabolizable energy recorded higher values for vetiver grass compared to clover hay (2.05 vs 1.83 Mcal/kg DM). The IVCPD, and total gas production were significantly increased with increasing the level of concentrates. The results suggested that vetiver grass is a promising feed resource for feeding small ruminants under desert conditions in Sinai. While, in vivo studies are needed to estimate their actual nutritive values and their effects on animal performance.
Evaluation of Continuous Assessment and Accounting Students’ Academic Achievement in Senior Secondary Schools in Rivers State

The study evaluated continuous assessment and accounting students’ academic achievement in senior secondary schools in Rivers State. A survey, causal-comparative research design was adopted. A population of 120 Accounting students was selected from three senior secondary schools in Rivers State. The entire population was used as sample because of its small size and no sampling technique was required from the population. Instruments titled ‘Continuous Assessment Questionnaire’ (CAQ) and ‘Accounting Students’ Academic Achievement Questionnaire’ (ASAAQ) was developed. The instrument was validated by experts in the field of Measurement and Evaluation, while the reliability of the instruments were established by the calculation of Pearson’s Product Moment Correlation to obtain an index of 0.72. Means and standard deviations were used in answering the research questions, while the Pearson’s Product Moment Correlation analysis was used to test the null hypotheses at 0.05 alpha level. It was found that there is a significant relationship between assignment, teacher made tests, field projects and accounting students’ academic achievement in senior secondary schools in Rivers State. The study thus concluded that continuous assessment or schoolsbased assessment should test the total growth of students in the non-scholastic areas and therefore should be built into the teaching-learning process. Therefore it was recommended that higher institutions of learning should train teachers on how to effectively supervise their students during field project writing, develop and construct teacher made tests, and that seminars, conferences and workshops should be organized by the government to really sensitize the importance of classroom assessment to the students using assignment.
Variance estimation for complex statistics and estimators: Linearization and residual techniques

In a sample survey, in the absence of external information, the total of a variable is estimated using the Horvitz-Thompson estimator. Its variance is in turn estimated by calculating a fairly complex quadratic form, generally recursively. In this paper, this problem is assumed to be solved on the basis of a software capable of carrying out the calculation automatically. In the case of complex estimators (i.e., of the calibration type), and in that of non-linear statistics (substitution estimators), it is shown that the same tool may always be used provided an appropriate artificial variable is chosen. In all cases, this artificial variable provides an estimation of the variance that is approximately unbiased and constructed using the influence function technique as well as some asymptotic postulates. Many examples are provided for the use of this technique: complex but explicit functions of totals (correlation coefficient), implicit functions of totals, calibrated estimators, fractiles and rank statistics, statistics derived from factorial methods. 1.

Microwave-mediated pyrolysis of macro-algae†

Macro-algae (seaweed) is an abundant and, for the most part, under-utilised resource. This study has shown that microwave (MW)-mediated pyrolysis of seaweed occurs at extremely low temperatures and produces chemical rich bio-oils which are rich in aromatics, sugars and other high value chemicals.
Revisión sistemática del entrenamiento de fuerza en futbolistas pre-adolescentes y adolescentes (Systematic review of strength training in preadolescent and adolescent football players)

El objetivo del presente estudio fue realizar una revisión sistemática sobre los efectos de los programas de fuerza utilizados en futbolistas varones pre-adolescentes y adolescentes. Se analizaron un total de veinticinco artículos, en español o en inglés, a raíz de la búsqueda en PubMed, ISI Web of Knowledge y SportDiscus. Se encontró que el entrenamiento pliométrico, seguido del entrenamiento de fuerza-resistencia y el entrenamiento isoinercial, por ese orden, son los comúnmente empleados para el entrenamiento de fuerza en futbolistas pre-adolescentes y adolescentes. Sin embargo, en función del estado madurativo, y del bagaje motriz del jugador, parecen generar diferentes adaptaciones en estos, y por tanto, requieren de una individualización de la carga de entrenamiento en función de su nivel tanto físico, como técnico. Abstract. The aim of the study was to do a systematic review about the effects of strength programs used in pre-adolescent and adolescent male football players. A total of twenty-five articles, in Spanish or English, were analyzed by searching PubMed, ISI Web of Knowledge and SportDiscus. Plyometric training, followed by strength-resistance training and isoinertial training, in that order, were found to be commonly used for strength training in pre-adolescent and adolescent footballers. However, depending on the maturation state, and the player's motor experience, they seem to generate different adaptations in these, and therefore, require an individualization of the training load depending on their physical and technical level.
“Did you know this camera tracks your mood?”: Understanding Privacy Expectations and Preferences in the Age of Video Analytics

Abstract Cameras are everywhere, and are increasingly coupled with video analytics software that can identify our face, track our mood, recognize what we are doing, and more. We present the results of a 10-day in-situ study designed to understand how people feel about these capabilities, looking both at the extent to which they expect to encounter them as part of their everyday activities and at how comfortable they are with the presence of such technologies across a range of realistic scenarios. Results indicate that while some widespread deployments are expected by many (e.g., surveillance in public spaces), others are not, with some making people feel particularly uncomfortable. Our results further show that individuals’ privacy preferences and expectations are complicated and vary with a number of factors such as the purpose for which footage is captured and analyzed, the particular venue where it is captured, and whom it is shared with. Finally, we discuss the implications of people’s rich and diverse preferences on opt-in or opt-out rights for the collection and use (including sharing) of data associated with these video analytics scenarios as mandated by regulations. Because of the user burden associated with the large number of privacy decisions people could be faced with, we discuss how new types of privacy assistants could possibly be configured to help people manage these decisions.
Revisiting the Asset Fire Sale Discount: Evidence from Commercial Aircraft Sales

Using a sample of commercial aircraft transactions, the paper decomposes the raw fire sale discount on sales of aircraft by distressed airlines into three components: (i) quality impairment due to under-maintenance, (ii) misallocation to lower productivity users, and (iii) a liquidity component due to the immediacy of the sale. Results indicate that financially distressed airlines sell aircraft that have a lower life expectancy and lower productivity. We combine the two effects into a quality impairment adjustment that explains around one half of the raw liquidation discount. For the remaining discount of around 9%, we find no direct evidence of misallocation to lower productivity users and industry outsiders. Rather, the post-sale users of distressed aircraft have significantly higher productivity than the distressed sellers, while their productivity is similar to that of other (non-distressed) users. In summary, our results indicate that the inefficiencies associated with fire sales are likely to be lower than have been previously documented.
Pattern and determinants of obesity among undergraduate medical students of Delhi

Background: Obesity is one of the most serious public health challenge of 21st century. Overweight and obese children are more likely to develop non-communicable diseases (NCDs) like diabetes and cardiovascular diseases (CVDs) in their adolescent age group. For the last few years prevalence of obesity among adolescent has risen dramatically. According to few recent studies, prevalence of obesity is high among medical students. Aims and objectives of the research was to study the prevalence of obesity among undergraduate medical students and to assess the determinants of obesity.Methods: A cross-sectional study was conducted among 200 undergraduate medical students in a medical college of Delhi. A pre-designed, pretested and semi-structured interview schedule was used. And for anthropometric measurements, digital weighing scale for weight measurement, stadiometer for height measurement and non-stretchable inch tape for waist-circumference/hip-circumference (WC/HC) measurement. Results: A total of 200 medical students were surveyed for a period of 6 months. It was observed that according to World Health Organization (WHO) Asian – pacific classification of body mass index (BMI), 21% (42/200) were overweight and 29% (58/200) were obese. Among the study participants, socio demographic variables which were found to be associated with increased BMI were mother’s education (p value=0.02), father’s education (p value=0.01) and type of the area (p value=0.03). Occupation of mothers and father was not found to be significantly associated with the BMI.Conclusions: Medical students are our future doctors and role model for the community, so it is very important to modify the dietary and lifestyle factors in order to decrease the prevalence of overweight and obesity among medical students.

Modelling temperature-dependent current-voltage characteristics of an MEH-PPV organic light emitting device

We present results from a device model in which the current–voltage (I– V) characteristics of an ITO/MEH-PPV/Al organic light emitting device have been simulated over a range of temperatures by fitting the mobilities and barrier heights. Good agreement with experimental data has been achieved at temperatures of 200–300 K at bias voltages exceeding 2 V, but there are some shortcomings of the model at lower temperatures. We have found that a discrete trap level in the simulated device improved the fit of the simulated I– V data in the low field regime at high temperatures. It has also been noted in the experimental data that cooling the device led to improved efficiency, with the ratio of light output to device current increasing by a factor of approximately 50 times when the device was cooled from 300 to 10 K. The model exhibited increased efficiency upon cooling, provided the electron barrier height, bn, was decreased at a greater rate than the hole barrier height, bp.
Nanoscale UO2 and novel complex U(IV)-sulphate phase formation from electrolytically reduced uranyl sulphate solutions

Abstract Three different processes have been explored to determine the ranges of U-concentration and acidity (pH-value) for nanocrystalline U2+x precipitation from electrolytically reduced uranyl sulphate solutions. Precipitation of U2+x nanoparticles aggregates was found to occur only in the narrow range of pH ∼ 4.5 to 5 and for U-concentrations of ∼10-6 to 10-7 M. The solid phase crystallized with the typical UO2- fcc structure and with a crystallite size ≤3 nm. The average aggregate size was mostly ≤80 nm. At higher U-concentrations, ranging from [U]∼10-1 M at pH∼1.5 to [U]∼5×10-4 M at pH∼4.9, formation of microscale precipitates of a novel complex U(IV)-sulphate phase occurred, which was characterized by SEM/EDX-WDX, ICP-OES and XRD-powder diffraction. The crystal structure was identified with an orthorhombic cell (space group Cmca ), with the following lattice parameters: a=1.9740(2) nm, b=1.3336(2) nm and c=2.0643(2) nm. Further composition analyses indicated a basic sulphate hydrate of the type Na3U(SO4)3(OH)·nH2O.
Nutrient digestibility of green seaweed Ulva meal and the influence on growth performance of Nile tilapia (Oreochromis niloticus)

Green seaweed Ulva had a high growth rate and spread in all of Indonesian waters. Species Ulva had a complete nutrient content that made it potential to be used as an alternative fish feed ingredient. This experiment was conducted in two series of trial, digestibility measurement of Ulva meal and its effects on the growth performance of the Nile tilapia (O. niloticus). In measuring the nutrient digestibility, a protein rich diet was formulated with a test diet in which 30% of the reference diet was replaced with Ulva meal, used Cr2O3 as an inert marker. Fish with initial weight about 16±0.35 g were stocked with a density of 15 fish per aquarium and collecting faeces is carried out until sufficient sample was available for analysis. The growth trial was conducted using a completely randomized design with four treatments and three replications. The experimental diets were U0 (Ulva 0%), U10 (Ulva 10%), U20 (Ulva 20%) and U30 (Ulva 30%). The Nile tilapia with an average body weight of 3.42±0.01 g, were stocked into the 60x50x50 cm aquaria with 25 fish in each tank and cultured for 60 days. Fish were fed three times daily on those diets at satiation level. The parameters which evaluated were specific growth rate, protein retention, lipid retention, feed efficiency, survival rate and blood hematology of the Nile tilapia. The results of digestibility measurement showed that Ulva meal had acceptable nutrients as an ingredient in Nile tilapia diet. Protein digestibility of Ulva meal was 87.36%, while lipid was 93.05%. The results of growth trial revealed that fish fed on 10% Ulva meal tended to have highest growth performance than those fed to the control, while the survival rate and fish health seemed not to be affected directly (P>0.05).
Efﬁcient COVID-19 Testing Using POMDPs

A robust testing program is necessary for containing the spread of COVID-19 infections before a vaccine becomes available. However, due to an acute shortage of testing kits (especially in low-resource developing countries), designing an optimal testing program/strategy is a challenging problem to solve. Prior literature on testing strategies suffers from two major limitations: (i) it does not account for the trade-off between testing of symptomatic and asymptomatic individuals, and (ii) it primarily focuses on static testing strategies, which leads to signiﬁcant shortcomings in the testing program’s effectiveness. In this paper, we introduced a scalable Monte Carlo tree search based algorithm named DOCTOR, and use it to generate the optimal testing strategies for the COVID-19. In our experiment, DOCTOR’s strategies result in ∼ 40% fewer COVID-19 infections (over one month) as compared to state-of-the-art static baselines. Our work complements the growing body of research on COVID-19, and serves as a proof-of-concept that illustrates the beneﬁt of having an AI-driven adaptive testing strategy for COVID-19.
Insider Investment Horizon January 2016

We examine the relation between insiders’ investment horizons and the informativeness of their trading activity regarding future stock returns. We show that both purchases and sales by short horizon insiders are more informative than those by long horizon insiders. Short horizon insiders better predict earnings surprises and large stock price changes. They also tend to come from firms with weaker corporate governance, be male, hold MBA or non-PhD degrees, and trade less following SEC investigations. The results are robust to alternative definitions of investment horizon, model specifications, and controlling for various characteristics of the insider, the trade, and the firm.
ESTIMATES OF CORRELATION COEFFICIENT, PATH ANALYSIS AND STEPWISE REGRESSION FOR SOME QUANTITATIVE TRAITS IN BREAD WHEAT

Twenty-five local and exotic wheat genotypes (Triticum aestivum L.) had evaluated to establish genetic variability, correlation coefficient, parameters, the interrelationships, direct and indirect effect and stepwise regression of various wheat components on grain yield. The study was conducted on the Experimental Farm of Gemmeiza Agriculture Research Station, Egypt during two seasons (2018/2019 and 2019/2020). Mean square analysis for the studied characters showed highly significant differences between most of the studied characters except, no. of spikes/m 2 in the second season. According to the results of mean performance, it may be noted that the studied genotypes out yielded grain yield /plot of the overall of the two years. The results of genetic parameters indicated that, both of phenotypic and genotypic coefficients of variation reflected high values, which estimated for three characters; Grain yield /plot followed by grain filling rate and spike weight, respectively. Broad sense heritability cleared that there was graduation for all of studied characters, which values ranged from 50.57 for no. grains/ spike to 93.06 for days to maturity. Three characters; days to heading, days to maturity and plant height gave a small significant values with grain yield character as well as no. spikes/m 2 for phenotypic correlation. Meanwhile, the remain studied characters may showed highly significant values for both of phenotypic and genotypic correlations and could be considered as a good criteria for selection to improve the performance of grain yield. The results for path coefficient illustrate that, the most important sources of variation in grain yield are the direct effect of spike weight followed by 1000-kernel weight. As for a positive indirect path coefficient; seven positive indirect path coefficients were found as follow: grain filling rate had the highest indirect effect, an appreciable indirect effect via spike weight followed by the relationship between grain filling rate via no. spike/m 2 , grain filling rate via no. spikes/m 2 , grain filling period via spike weight, spike weight via no. spike/m2, grain filling period via no. spikes/m 2 and grain filling period via no. spike/m 2 . On contrary, two negative indirect path coefficients appeared among 1000-kernel weight via spike weight and 1000-kernel weight via no. spike/m 2 . Stepwise regression analysis showed that, grain filling period, grain filling rate and plant height as important traits affecting grain yield in wheat
