roposed technique's superiority is confirmed in terms of convergence to the optimal solution. The simulation results confirm that the proposed REMS has contributed to better adoption of a cleaner energy production system, as the scheme significantly reduces fuel consumption, CO 2 emission and COE by 92.4%, 92.3% and 79.8%, respectively as compared to the conventional D g e n . The comparative evaluation of the algorithms shows that REMS-GOA yields a better result as it offers the least COE (objective function), at $0.3656/kW h, as compared to the REMS-CSA at $0.3662/kW h and REMS-PSO at $0.3674/kW h, for the desired DPSP of 0%. Finally, sensitivity analysis is performed to highlight the effect of uncertainties on the system inputs that may arise in the future.In January 2020, a cluster of pneumonia cases was reported in Wuhan, China. A global pandemic followed. The infection, called novel coronavirus disease 2019 (COVID-19), is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Common symptoms of COVID-19 illness included fever, cough, and abnormal findings on chest computed tomography. Nucleic acid testing, in the form of real-time reverse transcriptase polymerase chain reaction, is essential for diagnosing COVID-19 from respiratory samples from infected patients. Still, many questions remain surrounding the optimization of pre-analytical factors, such as specimen selection, collection, and transport. This review summarizes the current publications that describe viral density and specimen suitability for molecular detection methods. Of note, many of the reports represent studies with small sample sizes, and information may change as more is learned about specimen types as the pandemic continues.Business models have being designed, worldwide, to create sustainability competencies and in particular to incorporate reverse logistics, but Brazilian executives have not yet fully adhered to Law 12,305 on solid waste and reverse logistics. What would be the Brazilian executives' perception about reverse logistics competency and the support provided by a collaborative and IT competency? The objective of the paper is to investigate the effects of collaboration and IT competency in developing reverse logistics competency, as a strategy, and its consequences in economic and environmental performance. [https://www.selleckchem.com/products/ly2606368.html LY2606368] A survey was performed with 320 Brazilian supply chain executives and analyzed using Structural Equation Modeling. The models demonstrated that collaboration has a direct positive influence on the development of reverse logistics competency, by executives' point of view. The moderation effect between collaboration and IT competency for reverse logistics was not confirmed, since it was adopted a strategic view of reverse logistics. Therefore, despite there was not a moderation effect, IT presented a lower direct effect on reverse logistics competency. Results reinforce that organizations that develop reverse logistics competency tend to improve their economic and environmental performances.The Maastrichtian carbonates of the Tarbur Formation from the Zagros zone (SW Iran) are very rich in larger Foraminifera. Additionally, smaller benthic Foraminifera occur as well, one of them presented here as Zagrosaria pinnata gen. et sp. nov. It occurs abundantly at the Mandegan section within two levels corresponding to the lower photic zone. Based on the existence of a central pile along with an umbilical plate, and the lacks of true interiomarginal apertures, likely represented by a perforate surface, the suprageneric placing of Zagrosaria gen. nov. remains controversial. The ultimate aperture is represented by a central elongate double-bifid slot that arguably lies on a finely perforated and heavy feathered apertural face. Based on the reduced dimensions and lack of dimorphism the new taxon could be considered an epifaunal or shallow-infaunal r-strategist.Economic shutdowns, which refer to disallowing employees to work on site, are among the most contentious approaches to reduce the spread of COVID-19. While economic shutdowns save lives, their large economic costs have caused some people to develop strong attitudes and even break government-issued mandates, which incurs health risks and often the need to extend the economic shutdowns. In the current article, we argue that the interaction of two personality characteristics, risk-taking tendencies and prosocial tendencies, is a strong determinant of attitudes toward economic shutdowns, and we assess the impact of this interaction on three different attitudes toward economic shutdowns that differ by their focal target employees, customers, and organizations. The results demonstrate that this interaction significantly predicted economic shutdown attitudes toward customers and organizations but not employees. We suggest that these results can be understood via the lens of behavioral decision-making theories as well as a recent framework on antisocial risk takers, both of which provide several subsequent directions for future research. We conclude with recommendations for the development of effective messages to curb defiant behaviors toward economic shutdowns, such as focusing on those most likely to perform these problematic behaviors - the daring and uncaring.The present study aimed to broaden the investigation of personality traits and donation behaviour beyond the Five-Factor Model (FFM) framework. A sample of 506 participants completed the Supernumerary Personality Inventory (Paunonen, 2002), reported both their frequency of charitable giving and, given the option to donate potential lottery winnings to a charitable cause, the amount that they would donate. Religiosity was moderately positively correlated with charitable frequency, while integrity was weakly positively correlated with donation amount. Manipulativeness and egotism were weakly negatively correlated with donation amount. Overall, the results show limited evidence for the relevance of Supernumerary Personality Inventory personality traits in prosocial behaviour. Suggestions for future research are discussed.This study aimed to investigate the multiple mediating effects of perceived social support and anxiety between collective self-esteem and perceived stress during the 2019 coronavirus disease (COVID-19) pandemic. From February 18 to 25, 2020, 1921 participants aged 18-68 were recruited to complete the questionnaire online. The results showed that collective self-esteem reduced the perceived stress by increasing perceived social support and decreasing anxiety, and their chain mediation path. Our findings identified the important factors in reducing perceived stress and their relationship, which can be used to develop interventions to improve the mental health of the general public during the COVID-19 pandemic.
