Advanced sodium fast reactor accident source terms : research needs.

An expert opinion elicitation has been used to evaluate phenomena that could affect releases of radionuclides during accidents at sodium-cooled fast reactors. The intent was to identify research needed to develop a mechanistic model of radionuclide release for licensing and risk assessment purposes. Experts from the USA, France, the European Union, and Japan identified phenomena that could affect the release of radionuclides under hypothesized accident conditions. They qualitatively evaluated the importance of these phenomena and the need for additional experimental research. The experts identified seven phenomena that are of high importance and have a high need for additional experimental research: High temperature release of radionuclides from fuel during an energetic event Energetic interactions between molten reactor fuel and sodium coolant and associated transfer of radionuclides from the fuel to the coolant Entrainment of fuel and sodium bond material during the depressurization of a fuel rod with breached cladding Rates of radionuclide leaching from fuel by liquid sodium Surface enrichment of sodium pools by dissolved and suspended radionuclides Thermal decomposition of sodium iodide in the containment atmosphere Reactions of iodine species in the containment to form volatile organic iodides. Other issues of high importance were identified that might merit further research as development of the mechanistic model of radionuclide release progressed.
Clinical analysis of peritonitis in peritoneal dialysis patients

Introduction/Objective. Peritoneal dialysis is a method of treating patients in the terminal phase of renal failure (end-stage renal disease). Peritonitis represents most severe and most common complication of peritoneal dialysis. The most common peritonitis causes are Gram negative microorganisms: Staphylococcus-coagulase-negative, Staphylococcus aureus, Streptococcus sp, Neisseria sp. Gram negative microorganisms are: Pseudomonas sp, Enterococcus, Klebsiella sp, Proteus sp, Acinetobacter sp. The aim of the study was to examine the incidence of peritonitis and to determine the differences between patients with and without peritonitis and catheter infection. Other goals of the work were: the most frequent causes of peritonitis, the outcome of treatment, the influence of the length of treatment on the development of peritonitis, the influence of the peritoneal dialysis adequacy on the development of peritonitis, the influence of anemia, nutritional status, iron status, secondary hyperparathyroidism (Ca, P, CaxPO4, parathormone), protein status ? albumin and the effect of acid uricum on the development of peritonitis. Methods. Retrospectively, 84 patients were analyzed of peritoneal dialysis (2012? 2016) at the Kragujevac Center for Nephrology and Dialysis of Clinical Center. The diagnosis of peritonitis was based on clinical picture, biochemical analyses, leukocyte in sediment of dialysis, findings of peritoneal-culture, signs of inflammation (C-reactive protein, leukocytes). The analysis included: the most common causes, the outcome of treatment, the influence of the length of treatment, the influence of the peritoneal dialysis adequacy, the influence of anemia, the influence of iron status, the influence of secondary hyperparathyroidism, the influence of protein status - albumin, and the effect of acid uricum on the development of peritonitis. Results. In total, 22 patients had one, six patients had two, six patients had three, six patients more than three episodes of peritonitis. The difference in mean values of the number of erythrocytes, hemoglobin, hematocrit, iron, albumin, diastolic pressure, systolic pressure between patients with peritonitis, and those without it, were statistically significant (p < 0.05). The difference in mean values of calcium (Ca), phosphor (P), CaxPO4, uricum value, parathormone, peritoneal dialysis adequacy, systolic pressure was not statistically significant (p > 0.05). The incidence of peritonitis and death were not associated (p = 1.000). Conclusion, Peritonitis is severe complication of peritoneal dialysis. Anemia and nutritional status are risk factors that affect the development of peritonitis in patients on peritoneal dialysis.
THE ROLE OF ETHICAL LEADERSHIP IN INCREASING EMPLOYEES' ORGANIZATIONAL COMMITMENT AND PERFORMANCE: THE CASE OF HEALTHCARE PROFESSIONALS

Today's organizations are looking for ways to improve the organizational commitment and performance of employees in order to have a qualified workforce and maintain sustainability. Organizational leaders' approach to increasing employee motivation positively affects their organizational commitment and job performance. This research, basically focusing on the health sector, tried to specify the effect of the managers’ ethical approach on employees’ organizational commitments, performances, and the role of organizational commitments in this effect. The sampling was composed of 362 healthcare professionals. In this cross-sectional field study, an independent variable model for the ethical leadership approaches and a dependent variable model for the employees’ performance and commitment to their organizations were practiced. Data was collected through Ethical leadership, Organizational Commitment, and Individual Performance Scales. The data collected were analyzed through SPSS and AMOS package programs. A correlation analysis to specify the relationships between the variables and a regression analysis was done to specify the interaction. In specifying the intermediary role of organizational commitment, Structural Equation Model (SEM) was used. The results of the analyses showed positive significant relationships between ethical leadership approaches and organizational commitment and employees’ performance. It was also observed that ethical leadership approaches had a positive and meaningful effect on affective, continuous and normative commitment, the sub-dimensions of organizational commitment, as well as the employees’ performance. On other important finding is employees’ attendance and normative commitment are highly affected by ethical leadership approaches. As a result, it was specified that ethical leadership approaches by the managers are highly effective on employees’ performance and their commitment. It was also noted that organizational commitment played a mediator role on ethical leadership approaches. These findings were seen to be amicable with findings in previous studies. It is expected that this research will contribute to the literature because it is a holistic model including the relationships between variables.
How Individual States and Traits Predict Aesthetic Appreciation of Haiku Poetry

The factors influencing poetry’s aesthetic appreciation are largely unknown. Some studies have reported features that affect the aesthetic appreciation of poetry. This study sought to determine which states and traits predict the aesthetic appeal of haiku poetry. We recruited 277 participants to rate 36 haiku on five characteristics: imagery vividness, stimulus valence, arousal, valence of felt emotion, and aesthetic appeal of haiku. Then, participants completed questionnaires that assessed their own traits. We found both valence of felt emotion and imagery vividness generally predicted haiku’s aesthetic appeal; additionally, the influence of imagery vividness on aesthetic appeal was partially mediated by valence of felt emotion. As mental imagery fosters emotional evocation, vivid imagery increases positive felt emotions associated with aesthetic appeal. Furthermore, the traits of visual imagery ability, awe-proneness, and nostalgia-proneness predicted haiku’s aesthetic appeal. This study advances our knowledge of how individual states and traits determine the aesthetic appeal of haiku.
Delta-doped β-gallium oxide field-effect transistor

We report silicon delta doping in gallium oxide (β-Ga2O3) grown by plasma-assisted molecular beam epitaxy using a shutter pulsing technique. We describe the growth procedures that can be used to realize high Si incorporation in an oxidizing oxygen plasma environment. Delta doping was adopted to realize thin (12 nm) low-resistance layers with a sheet resistance of 320 Ω/square (mobility of 83 cm2 V−1 s−1, integrated sheet charge of 2.4 × 1014 cm−2). A single delta-doped sheet of carriers was employed as a channel to realize a field-effect transistor with current ID,max = 236 mA/mm and transconductance gm = 26 mS/mm.
First Report on Better Functional Property of Black Chicken Meat from India

Background: Indian domesticated chickens have a wide variety of phenotypes. Unlike other chicken breeds, Kadaknath chicken has black meat and is used by indigenous tribal people for its invigorating and therapeutic properties. To look for the functional traits that might be contributing towards the acclaimed benefits, free radical scavenging capacity and metal chelating ability of Kadaknath meat were explored for the first time in comparison to the commercial Cobb broiler. Methods: During the period 2018-2020, breast and thigh meat were collected from chickens (n=20/ group) at their commercial slaughter age. Meat extract was used for qualitative evaluation of protein as well as the antioxidant capacity utilizing diverse in vitro methods corresponding to different antioxidation mechanisms.Result: Protein concentration (g/100g of tissue) in Kadaknath breast (25.25 ± 0.31) and thigh (19.98 ± 0.29) meat was significantly (P less than 0.05) higher than the Cobb. Breast meat had better scavenging capacity than the thigh. The superiority of the antioxidant capacity of Kadaknath meat was explicitly established by more than one in vitro assay. Free radical scavenging assays viz. 2,2-azinobis (3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS); 1,1-diphenyl-2-picrylhydrazyl (DPPH) and Cupric reducing antioxidant capacity (CUPRAC) had significantly (P less than 0.05) higher values for Kadaknath in comparison to the Cobb broiler meat. Ferric reducing antioxidant power (FRAP) values (mM Fe2+/g of tissue) were also more in breast meat of Kadaknath (26.97±0.37) than the Cobb (15.24±0.40). Similarly, FRAP values were higher in Kadaknath (33.85±0.47) than the Cobb (19.2±0.31) thigh meat. Kadaknath had higher antioxidant capacity as reflected by metal chelation inhibition value. These findings help to explain the unique nutritional and functional characteristics of Kadaknath black-bone chicken and provide basic research data for exploring the commercial potential of its meat in the fields of functional foods, cosmeceuticals and nuutraceuticals.
Wideband Integrated Quad-Element MIMO Antennas Based on Complementary Antenna Pairs for 5G Smartphones

In this article, a wideband and highly-integrated quad-element multiple-input multiple-output (MIMO) antenna is proposed for the first time, to adapt to the size-limited environment in fifth-generation (5G) smartphones. First, the wideband decoupling between two extremely closely-spaced open-slot antennas with face-to-face and back-to-back configurations are investigated. Then, based on the complementary antenna pairs, wideband integrated quad-element MIMO antennas are implemented by the ingenious combination of these antenna pairs. For validation, an $8 \times 8$ MIMO system, constituted by two sets of integrated quad-antenna configurations, is simulated, fabricated, and measured. Both the simulated and measured results show that the $8\times 8$ MIMO system can provide isolation of better than 10 dB between any two ports and a total antenna efficiency of 52.8%–70.8%/40.5%–75.0% across 3.3–5.0 GHz. Compared with the existing integrated quad-antenna design schemes, the proposed solution can expand the bandwidth from less than 200 to 1700 MHz, covering the entire 5G N77, N78, and N79 bands. In addition to the integrated quad-antenna design, further extension to integrated multiantenna configurations is also discussed by the flexible combination of complementary antenna pairs, which paves the way for future higher-order MIMO system in smartphones.
The Effects of Duration of Cooking Pigeon Pea (Cajanus Cajan) Seeds on the Performance and Carcass Characteristics of Broiler Chicks

Two hundred and seventy (270) one week old broiler chicks of Aboricae breeds were fed diets containing pigeon pea seeds boiled for 0, 30, 40, 50 and 60 minutes on a control diet containing full-fat soy bean. Birds were randomly assigned to pens and treatments in a completely randomised design trial. There were 3 replications of the 6 treatments and 15 birds per pen. 23% crude protein (CP) diets were fed during the starter phase and 20% CP diet during the finisher phase. Feed and water were supplied ad-libitum throughout the 8-week trial period. At the end of the feeding trial, 2 birds were selected from each oen and slaughtered for carcass evaluation. During the starter and finisher phases, feed intake of birds were similar across treatments. The final weight gain of birds fed the control diet were significantly better than those of birds fed the raw or boiled pigeon pea during the 2 phases. Birds fed pigeon pea seeds boiled for 30, 40, 50 or 60 minutes had better (P<0.05) gain and final weights compared to those fed raw pigeon pea. Slaughter weights of birds fed the control diet and diets with pigeon pea boiled for 30, 40, 50 or 60 minutes were similar and significantly (P<0.05) better than those of birds fed raw pigeon pea diet.
Event quality, perceived value, satisfaction and behavioural intentions in an event context

ABSTRACT Understanding consumer experiences constitutes a central interest for event and destination managers. This study applies event quality incorporating affective and cognitive aspects of event experiences as a measure of the event experience. The measure is used to predict perceived value, satisfaction and behavioural intentions. The article contributes with a deeper understanding of how to measure and assess event attendees’ experiences in terms of affective and cognitive components in order to forecast event consumers’ behavioural intentions. The importance and mediating role of perceived value and satisfaction are tested. The conclusions stress the significance of affective aspects of experiences in understanding perceived value of experiences. A broader approach to the event experience is promising within an event, tourism and destination management perspective when developing existing and new event concepts as well as event portfolios.
COMPARING EFFICIENCY OF SAVING AND CREDIT COOPERATIVES OWNED BY GOVERNMENT EMPLOYEES AND GENERAL PUBLIC IN JAKARTA: A DATA ENVELOPMENT ANALYSIS APPROACH

Cooperatives have an essential role in Indonesian economy due to their contribution to the provision of capital within employees and societies. The government of Indonesia makes it easier to establish cooperatives, causing the number of cooperatives to increase over time. Therefore, it becomes necessary to study the effectiveness and efficiency of their resource management. This study aims to examine the efficiency of cooperatives in terms of input variables, namely members, total capital, and operational costs and output variables, namely profits, assets, loans, and debt repayments. The saving and credit cooperatives used in this study are owned by government employees (first type) and the general public (second type). 22 cooperatives based in DKI Jakarta were taken as the sample of this study. 11 of them are owned by government employees, and the remaining 11 were managed by the general public. The efficiency of these two types of cooperatives was analyzed separately and then compared using the Data Envelopment Analysis (DEA) method. The findings of this research indicated that the average efficiency of the first type of cooperatives was smaller than that of the second. This means that those saving and credit cooperatives have yet to reach the maximum level of efficiency according to the input and output variables. However, the average value of efficiency of those cooperatives is at a good level. Besides, the results of this research also showed that the cooperatives established by the general public had higher efficiency than the cooperatives possessed by government employees.
Returning to Work Following Spousal Loss? The Experiences of Widowed Parents

Families with children in the home who lose a parent to death are not only faced by bereavement but quite often a whole array of other changes. One area that has so far been overlooked in research is the return to work of the surviving parent. In this online survey of widowed parents, four out of five (81.6%, n=71) had experienced changes in their working or student conditions as a direct result of losing their partner. The experienced changes were mainly seen in relation to increased sick leave, reduced working hours, redundancy, and a change of jobs. Thematic analyses of participant responses to open-ended questions resulted in four different themes: Feeling overburdened, Grief as a process, Unaccommodating workplace, and Accommodating workplace. The results of this study highlight a need for focusing on the return to work of bereaved employees who have lost a co-parent.
The impact of ethical leadership on organizational citizenship behaviors: Moderating role of organizational cynicism

Abstract The aim of this study was to test the relationship between ethical leadership (EL) and organizational citizenship behaviors (OCB) and to test the moderating role of organizational cynicism (OC) in this relationship. This study was conducted on a stratified random sample consisting of 400 faculty members and their assistants at the Sohag University in Egypt. We relied on the survey for data collection and were analyzed using simple regression, hierarchical regression moderated analysis (HRMA) and simple slope analysis. Results indicate that ethical leadership has a direct and indirect effect on organizational citizenship behaviors and Organizational cynicism modifies the relationship between ethical leadership and organizational citizenship behaviors so that the relationship is weaker among employees with a high level of cynicism in contrast to those with a low level of cynicism. Finally, we offer several conclusions concerning EL, OCB and OC.
Diamane: design, synthesis, properties, and challenges

Abstract Diamane, the two-dimensional counterpart of diamond, is achieved from bi-layer graphene (BLG) or few-layer graphene (FLG) through surface chemical adsorption or high-pressure technology. Diamane with interlayer sp 3 bonding is found to have excellent heat transfer, ultra-low friction, high natural frequency, and tunable band gap, which shows the potential technological and industrial applications in nano-photonics, ultrasensitive resonator-based sensors, and improved wear resistance. In this review, we summarize the structure character, synthesis strategies, and physical properties of different diamanes, including hydrogenated diamane (HD), fluorinated diamane (FD), and pristine diamane (PD). In addition, we discuss the effect of functional groups, element doping, and stacking order on the physical properties of diamane. Finally, the remaining challenges and future opportunities for the further development of diamane are addressed.
Influence of flight altitude and control points in the georeferencing of images obtained by unmanned aerial vehicle

ABSTRACT This study aimed to explore the influence of flight altitude, density, and distribution of ground control points (GCPs) on the digital terrain model (DTM) in surveys conducted by unmanned aerial vehicles (UAVs). A total of 144 photogrammetric projects consisting of 399 aerial photos were carried out in a 2 ha area. These photogrammetric projects involved six GCP distributions (edge, center, diagonal, parallel, stratified, and random), six GCP densities, and four flight altitudes (30, 60, 90, and 120 m). The response surface methodology was used to find interference factors and total root-mean-square error (RMSEt) as well. The 60 m flight altitude presented was the most efficient. Central GCP distribution was observed to have low precision. Using stratified and random edge distributions, 10 GCPs are recommended to achieve geometric precision below 0.07 m at any flight height. However, for studies requiring up to 0.07 m precision, the best distribution was parallel with 4 GCPs at any altitude. Diagonal positioning of the GCPs showed RMSEt values below 0.11 m with 4 GCPs at any altitude. A good distribution of GCPs was found to be important, but the density of GCPs per image was more relevant when obtaining a lower RMSEt.
The Effect of Farmyard Manure and Mineral Fertilizers on Sugar Beet Beetroot and Top Yield and Soil Chemical Parameters

In order to recommend the dose of fertilization for sugar beet under currently unstable weather conditions, we analysed beetroot and top yields, sugar content (SC), and the effect of fertilization on soil chemistry over a three-year period (2016–2018). All three years were characterized by different weather conditions. The year 2016 was very warm and very dry. The year 2017 was warm with normal precipitation. The year 2018 was extraordinary warm and very dry. We compared the following ten fertilization treatments: unfertilized control, farmyard manure (FYM), mineral fertilizers NPK1–4, and FYM + NPK1–4. The applications of FYM, NPK, and FYM + NPK resulted in significantly higher yields of beetroots and tops as compared with the control, while no significant differences were recorded among FYM, NPK, and FYM + NPK treatments. The SC was not affected by the fertilization. The application of NPK resulted in a lower pH value, while the highest values were recorded for the control and FYM treatments. The application of FYM + NPK increased the content of organic carbon (Corg) in the soil, the total content of nitrogen (Ntot), and P and K concentrations. According to the results of the linear-plateau model, the recommended dose of N is 112 kg ha−1, corresponding to a beetroot yield of 66 t ha−1.
Production of a Human Metabolite of Atorvastatin by Bacterial CYP102A1 Peroxygenase

Atorvastatin is a widely used statin drug that prevents cardiovascular disease and treats hyperlipidemia. The major metabolites in humans are 2-OH and 4-OH atorvastatin, which are active metabolites known to show highly inhibiting effects on 3-hydroxy-3-methylglutaryl-CoA reductase activity. Producing the hydroxylated metabolites by biocatalysts using enzymes and whole-cell biotransformation is more desirable than chemical synthesis. It is more eco-friendly and can increase the yield of desired products. In this study, we have found an enzymatic strategy of P450 enzymes for highly efficient synthesis of the 4-OH atorvastatin, which is an expensive commercial product, by using bacterial CYP102A1 peroxygenase activity with hydrogen peroxide without NADPH. We obtained a set of CYP102A1 mutants with high catalytic activity toward atorvastatin using enzyme library generation, high-throughput screening of highly active mutants, and enzymatic characterization of the mutants. In the hydrogen peroxide supported reactions, a mutant, with nine changed amino acid residues compared to a wild-type among tested mutants, showed the highest catalytic activity of atorvastatin 4-hydroxylation (1.8 min−1). This result shows that CYP102A1 can catalyze atorvastatin 4-hydroxylation by peroxide-dependent oxidation with high catalytic activity. The advantages of CYP102A1 peroxygenase activity over NADPH-supported monooxygenase activity are discussed. Taken together, we suggest that the P450 peroxygenase activity can be used to produce drugs’ metabolites for further studies of their efficacy and safety.
