Soft-Template Synthesis and Characterization of ZnO2 and ZnO Hollow Spheres

Zinc peroxide (ZnO2) hollow spheres of 100−200 nm diameter were synthesized by a simple hydrothermal method by using H2O2 and ZnO powder as reagents without the assistance of any surfactant. O2 bubbles in situ generated by the decomposition of H2O2 served as a soft template in the formation of ZnO2 spheres. Zinc oxide (ZnO) hollow spheres were obtained by heat treatment of ZnO2 hollow spheres at 180 °C for 10 h in air. The products were characterized by XRD, FT-IR, TEM, HRTEM, and FESEM. The transition temperature of ZnO2 to ZnO was determined to be 229 °C by TG-DTA. Photoluminescence (PL) properties of the products were investigated and the origin of the two peaks at 392 and 448 nm in the PL spectrum of ZnO2 was discussed. Furthermore, the growth mechanism of the ZnO2 hollow spheres was discussed in detail.
Experimental Studies and Modeling of Divertor Plasma Detachment in H-Mode Discharges in the ASDEX Upgrade Tokamak

Plasma operation with high radiated power fractions and divertor detachment are investigated with experiments and modeling. The first stable, completely detached H-mode plasmas in ASDEX Upgrade with a full tungsten first wall has been achieved by nitrogen seeding with radiated power fractions of 85 %. The modeling reconciles almost all the experimental measurements with the simulations and recovers the phenomena observed in the experiment during detachment.
Factorial and Convergent Validity Evidence of the Need- Supportive Behaviors Scale With Health Science Students

Adaptive motivation is central to positive functioning. Social agents such as teachers play a significant role in shaping the motivation of people with whom they interact by satisfying or thwarting their psychological needs of autonomy, competence, and relatedness. The development and validation of tools that assess the types of behaviors social agents adopt to satisfy these psychological needs are important agenda items for substantive and applied researchers. In this study, we examined factorial and convergent validity evidence of a need support scale adapted from the physical education context for use in tertiary settings with health science students. Factor analyses of responses from 290 health science students indicated that need-supportive behaviors are best captured by one latent factor, rather than the a priori 4-factor structure designed to capture needs for autonomy, relatedness, and competence. Regression analyses supported the convergent validity of the unidimensional structure, such that students who perceived higher levels of need-supportive behaviors from their tutor reported higher levels of behavioral engagement, and experiences of vitality and learning. Validation of a scale that assesses needsupportive behaviors within a health science context provides researchers with a tool to employ in future research that aims to investigate the antecedents and outcomes of such behaviors, as well as the effects of interventions designed to equip educators with the skills, motivation, and knowledge to employ successfully such behaviors.
CAMBRIDGE WORKING PAPERS IN ECONOMICS Distributional Aspects of Microcredit Expansions

Various poverty reduction strategies are being implemented in the pursuit of eliminating extreme poverty. One such strategy is increased access to microcredit in poor areas around the world. Microcredit, typically defined as the supply of small loans to underserved entrepreneurs that originally aimed at displacing expensive local money-lenders, has been both praised and criticized as a development tool Banerjee et al. (2015c). This paper presents an analysis of heterogeneous impacts from increased access to microcredit using data from three randomised trials. In the spirit of recognising that in general the impact of a policy intervention varies conditional on an unknown set of factors, particular, we investigate whether heterogeneity presents itself as groups of winners and losers, and whether such subgroups share characteristics across RCTs. We find no evidence of impacts, neither average nor distributional, from increased access to microcredit on consumption levels. In contrast, the lack of average effects on profits seems to mask heterogeneous impacts. The findings are, however, not robust to the specific machine learning algorithm applied. Switching from the better performing Elastic Net to the worse performing Random Forest leads to a sharp increase in the variance of the estimates. In this context, methods to evaluate the relative performing machine learning algorithm developed by Chernozhukov et al. (2019) provide a disciplined way for the analyst to counter the uncertainty as to which algorithm to deploy. Reference Details CWPE Published 20100 3 November 2020
SE-ECGNet: Multi-scale SE-Net for Multi-lead ECG Data

Cardiovascular disease is a life-threatening condition, and more than 20 million people die from heart disease. Therefore, developing an objective and efficient computer-aided tool for diagnosis of heart disease has become a promising research topic. In this paper, we design a multi-scale shared convolution kernel model. In this model, two paths are designed to extract the features of electrocardiogram(ECG). The two paths have different convolution kernel sizes, which are 3×1 and 5×1, respectively. Such multi-scale design enables the network to obtain different receptive fields and capture information at different scales, which significantly improves the classification effect. And squeeze-and-excitation networks (SE-Net) are added to every path of the model. The attention mechanism of SE-Net learns feature weights according to loss, which makes the effective feature maps have large weights and the ineffective or low-effect feature maps have small weights. Our team name is CQUPT_ECG. Our approach achieved a challenge validation score of 0.640, and full test score of 0.411, placing us 8 out of 41 in the official ranking.
Effects of biofertilizer rate and application time on growth characters and grain quality of rice.

A field experiment was conducted to investigate effects of application time and rate of biofertilizer alone and in combination with chemical NPK fertilizer on growth, yield and quality of rice. The biofertilizer used composted food waste as substrate and added with effective microorganism. The treatments included recommended NPK fertilizer (RF, 11-5.5-4.8 kg 10a? ¹), half recommended NPK fertilizer (HRF, 5.5-2.8-2.4 kg 10a? ¹), half recommended NPK fertilizer plus 250 kg 10a? ¹ biofertilizer (HRF+Bio 250) and 500 kg 10a? ¹ biofertilizer (HRF+Bio 500). The biofertilizer treatments were applied at 0, 5 and 10 days before transplanting (DBT). Grain yield of HRF+Bio 250 at 5 DBT (648.4 kg 10a? ¹) was statistically similar to the highest obtained in the RF (654.1 kg 10a? ¹). Tiller numbers at HRF plus biofertilizer treatments were already high during the maximum tillering stage, and were similar with that of the RF and higher than that of the HRF during heading stage. Likewise, ripening ratio at HRF plus biofertilizer treatments was similar with that of the RF and higher than that of the HRF. Furthermore, all the biofertilizer treatments improved protein content but reduced the amylose content and palatability compared to treatments with chemical NPK fertilizer alone. Thus, HRF+Bio 250 at 5 DBT can be used to save 50% chemical NPK fertilizer and at the same time obtain an improved rice grain yield and quality.
THE EFFECT OF ADDING SOME ESSENTIAL OILS TO THE PHYSICOCHEMICAL PROPERTIES OF FROZEN BEEF SAUSAGE WITH DIFFERENT STORAGE PERIODS

This study was conducted for the purpose of determining the effect of adding 1% of essential oils (rosemary leaf oil, oranges peel oil, and lemon peel oil) to T2, T3, and T4, treatments respectively, and the effect of these additives on physicochemical properties, which include water-retaining meat. The loss percentage of exuded liquid, the loss percentage during cooking of frozen beef sausage at (-18 °C), and for different storage periods (1, 15, 30, 45 days), while T1 (Control treatment) was left without any addition. The results of the statistical analysis of the physicochemical properties on the treatments to which essential oils were added, showed no significant differences at (P <0.05) in meat capacity to retain water, the weight lost by dissolving character, and the losing characteristic during cooking, during cold and freeze storing and for the previously mentioned periods. It is concluded from this study that the treatments for which essential oils were added showed the best results in influencing the physicochemical properties of freeze stored beef sausage for a period of (45 days).
Photoelectron spectroscopic studies on a silicon interface with Bi2Sr2CaCu2BO8+δ high Tc superconductor

X‐ray and ultraviolet photoelectron spectroscopies have been used to investigate the interaction between silicon and Bi2Sr2CaCu2O8+δ high Tc superconducting material. For low coverages, silicon adatoms disrupt CuO bonds and SrO bonds to form a complex Sr‐Si‐O phase. This interlayer efficiently prevents further reaction between silicon and the Bi2Sr2CaCu2O8+δ superconductor.
THE POSSIBILITY OF COMBINING EARLINESS WITH HIGH SEED YIELD IN F1 GENERATION OF SESAME (Sesamum Indicum L.)

Diallel analysis has participated towards improving many crops as sesame. Thus, six parents were crossed in a half diallel mating to produce 15 F1s crosses (without reciprocal) at Agricultural Experiment and Research Station, Faculty Agriculture, Cairo University, Egypt in 2016 season. In 2017 season, genotypes (parents and 15 F1s crosses) were grown in randomize complete block design with five replications. The combining ability analysis was carried out using Griffing's method 4 fixed Model 1. The aim of this study was accomplished to develop serviceable genetic variability and would be of great importance in the selection of desirable lines possess earliness and high potential yield in the subsequence segregating generations. The results expressed that two crosses, P3 X P4, P3 X P5 had better seed yield plant-1 than their parents. Fourth parent was a good combiner for earliness, stem height to 1 capsule, 1000-seed weight, harvest index and seed yield plant. One cross (P3 X P4) showed high significant negative SCA effects for days to maturity and showed high significant positive SCA effects for 1000-seed weight and seed yield plant. Therefore, selection index which contains earliness and seed yield components will be apply in mulit locations and years would be effective to develop of sesame lines that have earliness and high seed yield in the subsequence generations.
Thermodynamic characteristics of cocrystal formation and melting points for rational design of pharmaceutical two-component systems

A database containing the fusion temperatures of two-component molecular cocrystals and individual compounds has been built based on literature analysis. Correlation equations were obtained connecting the fusion temperatures of cocrystals and individual components, which made it possible to design cocrystals with predictable fusion temperatures. An approach has been developed to estimate cocrystal sublimation thermodynamic characteristics. Thermodynamic functions of 79 cocrystals have been obtained and analyzed by the diagram method.
Angular Values of Nonautonomous and Random Linear Dynamical Systems: Part I - Fundamentals

We introduce the notion of angular values for deterministic linear difference equations and random linear cocycles. We measure the principal angles between subspaces of fixed dimension as they evolve under nonautonomous or random linear dynamics. The focus is on long-term averages of these principal angles, which we call angular values: we demonstrate relationships between different types of angular values and prove their existence for random dynamical systems. For one-dimensional subspaces in two-dimensional systems our angular values agree with the classical theory of rotation numbers for orientation-preserving circle homeomorphisms if the matrix has positive determinant and does not rotate vectors by more than $\frac{\pi}{2}$. Because our notion of angular values ignores orientation by looking at subspaces rather than vectors, our results apply to dynamical systems of any dimension and to subspaces of arbitrary dimension. The second part of the paper delves deeper into the theory of the autonomous case. We explore the relation to (generalized) eigenspaces, provide some explicit formulas for angular values, and set up a general numerical algorithm for computing angular values via Schur decompositions.
The F⋯HO intramolecular hydrogen bond forming five-membered rings hardly appear in monocyclic organofluorine compounds

This paper emphasizes that fluorine atoms in organic molecules need special geometric requirements to experience intramolecular hydrogen bonds (H-bonds). Calculations at the B3LYP/aug-cc-pVDZ theoretical level and using the quantum theory of atoms in molecules applied over a series of monocyclic compounds, which have similar CC(F)–C(OH)C fragments, predict that the F⋯HO intramolecular H-bond does not exist when forming five-membered rings. Indeed, it is shown that the geometric restrictions imposed by the rigid rings are the main reasons in preventing fluorine participating in such a F⋯HO intramolecular H-bond.
THE EFFICIENCY OF PLANT FORM BIOREACTOR AS TEMPORARY IMMERSION SYSTEM IN BUD AND MULTIPLICATION SHOOT VIA DIRECT ORGANOGENESIS OF DATE PALM UNDER LED LIGHT

The study was conducted in the Date palm micropropagation Unit belonging to College of Agriculture, University of Kufa during the period from October 2015 to June 2018 in order to determine the effect of different concentrations of 2iP added to the nutrient media and testing the efficiency of the temporary immersion system using the plantform bioreactor in increasing the number of produced shoots and quality in the multiplication stage of buds and shoots under LED light. The results showed Temporary Immersion System (TIS) using the plantform bioreactor was excelled in the number of shoots, fresh weight of Biomass, and its content of sugars compared with solid media, while the solid media is excelled in shoot length. Addition of 0.4 mg.L-1 2ip to the nutrient media led to effect on most indicators of the buds and multiplication shoots which led to increase of the number of shoots and their length, as well as the fresh weight of the biomass and dissolved sugars. Plantform bioreactor has shown remarkable efficiency in increasing the multiplication of shoots and other growth indicators and we recommend to incorporate it into the Date palm micropropagation protocol via direct organogenesis.

The properties of the Grimm‐type glow discharge as well as basic processes of sputtering are described and their influence on the GD as a surface and interface analytical tool are discussed. A series of examples from recent literature ranging from computer hard disks to molecular monolayers on copper substrates are presented to illustrate the excellent depth resolution that can be achieved with GD surface analytical techniques. The conditions for obtaining nanometer or even atomic‐layer depth resolution are discussed. Following this introduction is the possibilities of the technique a selection of applications principally chosen from our laboratories, demonstrating that GD‐OES and GD‐MS can be successfully employed as an analytical tool assisting the development of new materials and coatings. The applications cover common industrial tasks such as heat treatments, studies of diffusion processes at interfaces, and electrochemical depositions for biocompatible material. However, limitations and known artifacts are also discussed.

An experimental study on the effective dielectric constant of heterogeneous media

An effective dielectric constant of heterogeneous layers, in which BaTiO/sub 3/ particles are dispersed in a polymer mix, has been studied experimentally. When the experimental values of an effective dielectric constant for the BaTiO/sub 3/-polymer layers were plotted against the volume fraction of BaTiO/sub 3/, it was found that the experimental values were inside the Hashin-Shtrikman bounds and fit the van Beek theory. Changes in the effective dielectric constant for the Cu-particle-glycerinum system associated with the sedimentation of the Cu particles were also examined. The results obtained confirmed that the effective dielectric constant of a heterogeneous system changes, depending on the phase configuration, even at a constant volume fraction of each phase. <<ETX>>
Physicochemical, microbiological and coagulating properties of ewe's milk produced on the Calabrian Mount Poro plateau

Three hundred individual ewe’s milks and six bulk milks were analysed over two seasons. The results show that in spring but not in winter the milks examined conform substantially to the standards laid down by Italian legislation. Nevertheless, the data acquired constitute a good starting point from which the quality of ewe’s milk produced on the Calabrian Mount Poro plateau should be improved, by performing selection of sheep for mastitis resistance based on somatic cell count, improving the hygiene standards at the dairy, using selected autochthonous lactic starter cultures and, only if strictly necessary, thermal treatment of the milk.

Preparation of graphite-coated iron nanoparticles using pulsed laser decomposition of Fe3(CO)12 and PPh3 in hexane

Graphite-coated iron nanoparticles with high magnetization have been synthesized by 355 nm pulsed laser photodecomposition of triiron dodecacarbonyl Fe3(CO)12 in the presence of triphenylphosphine PPh3. The iron particles have been found to be stable toward oxygen and strong mineral acids. The graphite shell surrounding the iron core has been shown to possess defects on its outer layers, rendering them suitable for functionalization. These superparamagnetic spherical nanoparticles show a high magnetization value of 103.9 emu/g, as indicated by SQUID measurements. We believe that the as-prepared graphite-coated iron nanoparticles have great potential in magnetic resonance imaging and other biomagnetic applications.
Study of Numerical Diffusion in a Discrete-Sectional Model and Its Application to Aerosol Dynamics Simulation

ABSTRACT The discrete-sectional model is an important tool used to study aerosol dynamics, although it suffers inherent numerical diffusion errors that are dependent on the model parameters including section spacing, numerically conserved aerosol property, and number of discrete sizes. An analytical evaluation of the errors due to the deviations of the derived aerosol properties in the sectional formulation and the interchange between discrete-size and sectional aerosols is carried out. The errors are larger if the difference in the aerosol property function index (ξ) between the derived and conserved properties is larger. Results of parametric studies are reported for condensation and coagulation systems. The results for condensation systems show that the υ-model is better than the n-model and the υ2-model in predicting the integral properties of the size distribution. However, the deviation in the results between the n-model, υ-model, and υ2-model reduces as the section spacing is decreased. A finite va.
