Study of repeatability and phenotypical stabilization in kale using frequentist, Bayesian and bootstrap resampling approaches

The aim of this study was to obtain information for the genetic improvement of kale through repeatability and phenotypic stabilization studies and to compare methodologies that represent the reliability of the estimated parameters. Thirty-three half-sib progenies were evaluated in a randomized block design with three replicates and six plants per plot. Eight harvests were evaluated in terms of the yield of fresh leaves, number of shoots, number of leaves and average mass of leaves. Then, a phenotypic repeatability and stabilization study was performed, estimating the genetic parameters σ2a, σ²g, σ²e, and the coefficient of environmental variation and repeatability using the frequentist and Bayesian methodologies. To evaluate the reliability of these estimates, intervals were obtained using the frequentist, Bayesian and bootstrap methods. It was verified that the reliable selection of progenies of half-sib of kale can be achieved in four harvests that were realized between 95 and 170 days after planting. It was observed that the frequentist and Bayesian methodologies are better suited to obtain reliable estimates of the genetic parameters evaluated, as the last one provided smaller amplitudes for the obtained intervals. The bootstrap methodologies are not recommended for phenotypic repeatability and stabilization studies in kale.
The Dundee Ready Education Environment Measure (DREEM): Perception of educational environment and its impact on academic performance of medical, dental and pharmacy students

ABSTRACT Objective: To assess the perceptions of health professional students to educational environment and to ascertain differences among gender and faculties. The study also assesses the internal consistency of DREEM questionnaire of health profession students. Methods: A cross sectional, institutional based study was done during March to June 2017 among students of health professions of faculty of medicine and faculty of pharmacy at Hamdard University, Karachi. Using proportionate quota sampling technique, DREEM questionnaire was administered to both medical and pharmacy undergraduate students. Data was analysed by SPSS version 22. Descriptive statistics was used to calculate mean with standard deviation of overall DREEM and its five subscales. Independent sample t-test was used to identify gender and faculty related differences between perception of educational environment. Cronbach’s alpha was also calculated to test the reliability of DREEM questionnaire. Results: Out of 6oo students, fifty percent were selected from each faculty in which 327 (54.5%) were male students. Total mean score of DREEM was 130.1/200 (65%). Student’s academic self-perception domain got the highest score (97.1%) and the lowest score in students’ perceptions of atmosphere (47.7%). Statistically significant differences (P < 0.05) was found between student’s social self-perception and gender. A high level of reliability was found for the total DREEM inventory with an alpha coefficient of 0.82. Conclusion: More positive than negative educational environment of the university was found with no differences among medical and pharmacy students.

Evaluating the Effects of Casein Phosphopeptide Amorphous Calcium Phosphate Paste and Nano-hydroxyapatite Solutions on the Re-mineralization of Synthetic Primary Caries in Enamel

Background and Aim: It has now been well documented that dental caries can be re-mineralized before they become pitted. So this laboratory study examined the effect of CPP-ACP paste and Nano-hydroxyapatite solutions on remineralization of primary enamel caries lesions. Materials and Methods: 75 pieces of 3 mm × 4 mm were obtained from the buccal crown surface of 75 premolars drawn. Primary enamel lesions were created by putting samples, except for 15 that set aside by random, for 48 hours in demineralization solution. Then these 60 specimens were divided randomly into 4 groups of 15. 10 days pH cycle was completed and in 3 groups after the end of each day of cycle, the concerned test material was applied. Group 1: Healthy (positive control); Group 2: With primary lesions; Group 3: Applying CPP-ACP paste; Group 4: Applying 5% nano-hydroxy apatite solution; Group 5: Applying 10% nano-hydroxy apatite solution on the lesions. The rate of weight of calcium, phosphor and fluoride elements in all samples after the end of work was measured by SEM-EDS. Data analysis was perfumed using one way ANOVA and Post Hoc Bonferroni statistical tests (α=0.05). Results: There was a significant statistical difference between groups about the amount of calcium, phosphor and fluoride elements (p=.000). The rate of calcium and phosphor in the group having white spot lesions (WSL) significantly was less than the other groups (p=.000). The rate of calcium, phosphor and fluoride elements in the healthy groups wasn’t significantly different from the group under applying CPP-ACP paste and 5 nano-hydroxy apatite solution (p=1.000). But the group under applying 10% nano-hydroxy apatite solution significantly had more calcium and phosphor than the other 4 groups (even healthy or intact group) (p=.000). Conclusion: All three materials of CPP-ACP, 5% and 10% nano-hydroxy apatite solution are effective on the remineralization of the primary enamel lesions. Also 10% nano-hydroxy apatite solution is more effective than the other groups and results in strength of healthy tooth structure (without lesion).
Spatial distribution of precipitation and evapotranspiration estimates from Worldclim and Chelsa datasets: Improving long-term water balance at the watershed-scale in the Urabá region of Colombia

In this paper, we have evaluated high-resolution spatial gridded climate data from two long-term global datasets, WorldClim V.2. 0 and Chelsa V.1. 2, in representing variables like precipitation and temperature for the urabá region of Colombia. additionally, climate variables from these datasets have been used to estimate evapotranspiration using traditional methods such as the Turc, hargreaves and Thornthwaite equations. finally, the results of long-term spatial climate characterization are used to apply the water balance equation in the surface at the watershed scale, to obtain the long-term average streamflow of the main streams of the urabá region; these streamflows are compared with the observations of hydrological stations. We find that the WorldClim and Chelsa rainfall estimates show average differences between 20% and 23% compared to the average annual rainfall in the area from in situ measurements. both datasets are able to reproduce the rainfall average annual cycle, although Chelsa shows a slightly better performance. regarding near surface air temperature we find that WorldClim shows a good performance, while Chelsa significantly underestimates the average temperature. finally, we found that the hargreaves and Thornthwaite methods lead to the best performance in estimating streamflow from the water balance, probably because details of the seasonal behavior of variables like temperature and radiation are explicitly included in these methods. On the other hand, the Turc method yields larger estimates of evapotranspiration and therefore the corresponding derived streamflows are lower than those observed. The good performance of the WorldClim and Chelsa datasets in representing variables like precipitation, temperature, and the derived watershed-scale streamflow, suggest that these long-term global climate datasets can be used to study the spatial distribution of important hydrological variables in the urabá region of Colombia, and consequently the estimation of average streamflows through the method of the long-term water balance.
Room Temperature Formaldehyde Sensing of Hollow SnO2/ZnO Heterojunctions Under UV-LED Activation

The room temperature gas sensing properties of the hollow SnO2/ZnO heterojunction-based chemiresistive sensors under ultraviolet ${\left ({UV}\right)}$ radiation were investigated. The hollow SnO2/ZnO heterojunctions were fabricated using the template-assisted process followed with a hydrothermal treatment. The sensor using this core-shell SnO2/ZnO heterojunctions showed a much higher response to formaldehyde under UV illumination compared to that without UV. Moreover, the response of this hollow heterojunctions-based sensor to formaldehyde is higher than the respective pure SnO2 and ZnO hollow microspheres-based sensors under same conditions indicating the synthetic effect of the formed heterojunctions on the enhanced sensitivity. More strikingly, the response of the SnO2/ZnO heterojunctions-based sensors showed a much smaller response to ethanol, methanol, and toluene indicating an excellent selectivity whereas there is a large influence from ethanol if the sensor worked under the conventional heating method. It could be attributed to the lower oxidizing ability of the adsorbed, ionized oxygen with a negative monovalence on the oxide surface and thus a selective photo-catalytic conversion of formaldehyde over the other possible interferents. The long-term stability of the sensor operated under UV light was also studied.
Rights Offering and Its Effect on Share Price Movement: A Study of Commercial Banks

This paper examines the effect of rights share issue on share price movement in the banking sector covering the period 2007/08 to 2016/17. In order to find out the share price movement in different selected points of time, pre and post right issue and price relatives were calculated considering the price of 90 days before the right announcement date as the beginning index. Five different points of time were selected to observe the share price movements assuming the announcement date as the reference point of time. Stock price data were obtained from the website of NEPSE. The paper uses correlation coefficient to examine whether the overall market movement has any relationship with the individual share price change. Coefficient of determination is used to identify what proportion of the variation in the share price is explained by the event of right share issue. The result shows that right offering announcements have the signaling effect, but it is negative. The share price of Nepalese commercial banks decreases after the announcement of right in spite of the increase in the market index in the corresponding period. The results highlight the information asymmetry behavior which induces a negative change in share price after the rights announcements. The implication of the result is that investors can anticipate the nature of change in share price after rights issue announcements and develop strategic plans to improve the trading activity.
Understanding our potential research publics: Exploring boundary disputes in recruitment to a sociological study

The international debate on public sociology has failed to increase our understanding of how we might engage with new publics, particularly potential research publics. Parallel literatures exploring over-research, research fatigue, non-response and public (mis)understanding of sociology can shed light on how underlying boundary disciplinary issues might influence willingness to participate in sociological research. This article explores the case study of parents of people with Rett syndrome, an over-researched group at the centre of competing research discourses following a breakthrough in genetic research. Data from a wider study was used to explore reasons for research participation, non-participation and dropout, including interviews (n = 20) and a brief survey about reasons for non-response (n = 58). An individualist perspective led to interpretations of social interventions as stigmatising and refusal to participate. Parent activists fundraising for and promoting genetic research challenged notions of voluntary groups as being receptive to organic public sociology. While individual benefits were experienced, there were signs of research fatigue from multiple approaches. Finally, the close link between social activism and research participation increased the risk of unwitting exploitation, an issue of concern for organic public sociology.
Development of Oxygen-Plasma-Surface-Treated UHMWPE Fabric Coated with a Mixture of SiC/Polyurethane for Protection against Puncture and Needle Threats

Although considerable research has been directed at developing materials for ballistic protection, considerably less has been conducted to address non-firearm threats. Even fewer studies have examined the incorporation of particle-laden elastomers with textiles for spike, knife, and needle protection. We report on a new composite consisting of ultra-high-molecular-weight polyethylene (UHMWPE) fabric impregnated with nanoparticle-loaded elastomer, specifically designed for spike- and needle-resistant garments. Failure analysis and parametric studies of particle-loading and layer-count were conducted using a mixture of SiC and polyurethane at 0, 30, and 50 wt. %. The maximum penetration resistance force of a single-layer of uncoated fabric increased up to 218–229% due to nanoparticle loading. Multiple-layer stacks of coated fabric show up to 57% and 346% improvement in spike puncture and hypodermic needle resistance, respectively, and yet were more flexible and 21–55% thinner than a multiple-layer stack of neat fabric (of comparable areal density). We show that oxygen-plasma-treatment of UHMWPE is critical to enable effective coating.
Impact of Thickness of Polymer Electrolyte Membrane and Gas Diffusion Layer on Temperature Distributions in Polymer Electrolyte Fuel Cell Operated at Temperature around 90 °C

Polymer Electrolyte Fuel Cell (PEFC) is desired to be operated at temperature around 90 °C for stationary applications during the period from 2020 to 2025 in Japan. It can be expected thinner polymer electrolyte membrane (PEM) and gas diffusion layer (GDL) would promote the power generation performance of PEFC at this temperature. The aim of this study is to understand the impact of thickness of PEM and GDL on the temperature profile of interface between PEM and catalyst layer at the cathode (i.e., the reaction surface) in a single PEFC with an initial operation temperature (Tini). An 1D multi-plate heat transfer model based on temperature data of separator measured using thermograph in power generation process was developed to evaluate temperature of the reaction surface (Treact). This study investigated the effect of Tini, flow rate and relative humidity of supply gas on Treact distribution. The study finds that when using thin GDL, the even distribution of Treact – Tini is obtained irrespective of thickness of PEM, Tini and relative humidity conditions. Treact – Tini using Nafion 115 is higher than the other thin PEMs irrespective of Tini and relative humidity conditions. It can be concluded that the even temperature distribution could be achieved by using thin PEM and GDL.

Wealth, Warmth, and Well-Being: Whether Happiness is Relative or Absolute Depends on Whether it is about Money, Acquisition, or Consumption

A central question in consumer and happiness research is whether happiness depends on absolute or relative levels of wealth and consumption. To address this question, the authors evaluate a finer level than overall happiness and distinguish three specific types of happiness: with money, with the acquisition of an item, and with the consumption of an item. They find that happiness with money and with acquisition is relative and that happiness with consumption can be either absolute or relative, depending on whether the consumption is inherently evaluable or not. Including both lab and field data, this research yields implications for how to increase consumer happiness from one generation to the next.
Comparison of Hormonal Treatment Kisspeptin with GnRH and hCG on the some Reproductive Performance of Cyprus, Does during Non-Breeding Season

| The current study was conducted to investigate the influence of Kisspeptin, GnRH and hCG on some reproductive performance of Cyprus does during the non-breeding season. A total 55 Cyprus does 2-6 years old and averages 45 kg body weight. The does were randomly divided into five equal groups (11 does per group). The first group (B1) regarded as a control group, intramuscular injection with normal saline, whereas, the second (B2) and third (B3) groups were injected with 4 and 8 μg / kg body weight of Kisspeptin-10 intravenous respectively. The fourth (B4) and fifth (B5) groups were injected with hCG (250 IU / doe) and GnRH (20 μg / doe) intramuscular respectively. Bucks were introduced after 24h of the treatment in all groups, ensuring that does exhibit estrus were mated for three consecutive estrus cycles. There were significantly in kilogram kids per goats joined in group B2 (2.84±0.05 kg) and then group B5 (2.45±0.04 kg) compared with other groups. The kilograms born per goat kidding (P< 0.05) was lower in group B4 than other groups. Gestation length was significantly longest in group B1 as compared with other groups. Results showed that there were no significant different (P>0.05) male kid weight and female kid weight. In conclusion, kisspeptin-10 (4 μg/ kg/ animal) enhanced kilogram kids per goats joined and then GnRH in Cyprus goat does during nonbreeding season.
Evaluation of laminar flow of surfactant-stabilized bitumen-in-water emulsion in pipe using computational fluid dynamics: Effects of water content and salinity

Abstract Laminar flow of oil-in-water (O/W) emulsion in a horizontal pipe has been simulated to quantify the effect of salinity of aqueous phase and water content on flow characteristics using computational fluid dynamics (CFD). Bitumen was dispersed in aqueous solution containing surfactant at different NaCl concentrations and water contents. Rheological parameter was obtained from the viscosity-shear rate profiles of the fluid. Numerical modeling and simulation was performed using a finite element simulation software. The case was simplified by considering the O/W emulsion as a stable, pseudo-homogeneous (single-phase) fluid within the conditions investigated. At flow reference temperature, Tref = 30 °C, the pressure drop obtained from emulsion with 30% water content was 931 Pa, compared to 84.6 Pa which was obtained from 50% water content (i.e. reference fluid without NaCl). In addition, the pressure drop of 239 Pa, 142 Pa, 124 Pa, and 82.9 Pa was obtained from O/W emulsion samples containing 70000 ppm, 40000 ppm, 20000 ppm, and 10000 ppm salinity in the aqueous phase, respectively. Furthermore, the maximum dynamic viscosity imposed by the fluid, was calculated as ≈81000 cP for the sample containing 30% water content compared to ≈14000 cP from the reference fluid. The dynamic viscosity obtained from 70000 ppm salinity content was ≈34000 cP compared to ≈20000 cP, ≈16000 cP, and ≈13000 cP calculated for 40000 ppm, 20000 ppm, and 10000 ppm salinity, respectively. Moreover, large reduction in pressure drop (99%) and dynamic viscosity (60–90%), regardless of the water content and salinity were obtained from the simulation. Graphical Abstract
Health visiting and safeguarding children: A perfect storm?

Health visitors play an important role in safeguarding and protecting children. In this article we review current research evidence and professional literature about this aspect of health visiting and highlight some of the practice challenges in undertaking this work. Three critical issues are discussed: the invisibility and unquestioned nature of much health visiting safeguarding work; that health visitors with their clinical expertise and accepted home visiting role are well placed to undertake this type of work; and the challenges of ensuring effective safeguarding within the context of economic austerity. The article highlights the important contribution of contemporary health visiting to safeguarding children and child protection. It is important that this role is made explicit to those commissioning health visiting services for children in the early years.
An in-silico analysis of information sharing systems for adaptable resources management: a case study of oyster farmers

Information sharing systems are often viewed as a potential way of increasing scrutiny by actors of their interactions with natural resources. Scrutiny is then seen as encouraging sustainable and adaptable management of the resource. We tackle this claim by using an agent-based model to focus on the specific issue of oyster farmers dealing with the deadly OsHV-1 virus by sharing information about their own experience (practices and outcomes) via their social network and/or an information sharing system. We followed closely what access to such information sharing means for the environment (production), agents (beliefs) and interactions between the environment and agents (practices). In the model, introducing information sharing leads to a decrease in mortality rates and a convergence in agents’ beliefs. Agents stop changing their practices earlier when they share information, but heterogeneity in agent decision-making models leads to wider exploration of possible strategies and increased production. Agent-based modelling proved a suitable method for studying the impacts of information sharing.
