Results obtained in the microcosm study provided useful information in terms of soil aeration and nutrient amendment in view of a future biodegradation process scale-up.We address a question at the center of many policy debates how effective is the US safety net? Many existing studies evaluate the effect of one program on economic hardship in isolation, though families typically participate in multiple programs. Using 1992-2011 data from the Survey of Income and Program Participation, our analyses examine the simultaneous effect of participation in three programs, TANF, SNAP, or Medicaid/SCHIP, on a set of outcomes of intrinsic importance-measures of material hardship. We find that a 10 percentage point increase in participation in any of these three safety net programs by low-to-moderate income families with children reduces their average number of hardships by 0.11 (-0.41 elasticity), and the incidence of food insufficiency by 1.7 percentage points (-1.27 elasticity). This analysis suggests that hardship would be even more prevalent in the United States without the existence of the current safety net programs.Building on the concept of externalities, we propose an explanation of how multinationals can contribute to the enactment of the United Nations' Sustainable Development Goals as part of their ordinary investments. First, we suggest grouping the 17 Sustainable Development Goals into six categories based on whether they increase positive externalities - knowledge, wealth, or health - or reduce negative externalities - the overuse of natural resources, harm to social cohesion, or overconsumption. Second, we propose placing these categories within an extended value chain to facilitate their implementation. Third, we argue that multinationals' internal investments in host-country subsidiaries to improve their competitiveness contribute to addressing externalities in host-country communities, while external investments in host communities to solve underdevelopment generate competitiveness externalities on host-country subsidiaries.Rhodojaponin III is a grayanane-type diterpenoid natural product with a novel chemical scaffold. It shows potent antinociceptive activity and may represent a new class of natural non-opioid analgesics with a novel mode of action. We explored the Au(I)-catalyzed Conia-ene cyclization and the Mn(III)-mediated radical cyclization of alkynyl ketones for the synthesis of the bicyclo[3.2.1]octane fragment of rhodojaponin III. These strategies will be applicable in the synthesis of rhodojaponin III and analogs for future biological studies.This report describes the direct synthesis of dihydro-pyrrolo-pyrazole heterocycles from allylic azides and methyl vinyl sulfone. The product results from a complex cascade reaction that is operationally straightforward, with aromatization being the result of a concomitant elimination step. A variety of azides could participate in this reaction (12 examples) and the isolated yields of the desired product ranged from 51%-72%. Lastly the ethylene sulfone group could be removed by heating the product in pyrrolidine.It is witnessed that the role of technology became crucial, and people are dependent on technologies to continue creative, professional, and academic activities during a pandemic situation when most of the libraries were not accessible physically worldwide. This study aims to know the level of ICT skills, competencies, usage of technologies, challenges, and services offered by library professionals of Gujarat state, India during the lockdown period. Due to the emergence of advanced technologies, the omnipresence of the internet, the explosive growth of e-resource, and pandemic situation, it is imperative for library professionals to acquire new ICT skills, techniques and apply them to disseminate information and reach out to library patrons. This study reveals how library professionals provided services and resources to users when they need resources/ information and which techniques/ methods library professionals adopted to fulfill the requirements of patrons during COVID-19. The methods adopted by patrons to access library resources were also studied. The 100 questionnaires were circulated via social media and email to library professionals of Gujarat state and 77 (77%) responses received in this study.The sudden outbreak and uncontrolled spread of COVID-19 disease is one of the most important global problems today. In a short period of time, it has led to the development of many deep neural network models for COVID-19 detection with modules for explainability. In this work, we carry out a systematic analysis of various aspects of proposed models. Our analysis revealed numerous mistakes made at different stages of data acquisition, model development, and explanation construction. In this work, we overview the approaches proposed in the surveyed Machine Learning articles and indicate typical errors emerging from the lack of deep understanding of the radiography domain. We present the perspective of both experts in the field - radiologists and deep learning engineers dealing with model explanations. The final result is a proposed checklist with the minimum conditions to be met by a reliable COVID-19 diagnostic model.Amid the global threat caused by the coronavirus disease 2019 (COVID-19) pandemic, developing sufficiently rapid, accurate, sensitive and selective methods of diagnosing both symptomatic and asymptomatic cases is essential to alleviating and controlling the pandemic's effects. Pluronic F-68 mw This article describes an electrochemical immunoassay platform developed to determine the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) spike antibody by using gold-clusters capped with cysteamine, glutaraldehyde, the spike protein of the SARS-CoV-2 antigen and bovine serum albumin on a glassy carbon electrode. The electrochemical oxidation signal of the antigen-based immunosensor at 0.9 V was used to detect the SARS-CoV-2 spike antibody. When saliva and oropharyngeal swab samples were analysed, the recovery and relative standard deviation values were 96.97%-101.99% and 4.99%-5.74%, respectively. The method's limit of detection relative to the SARS-CoV-2 spike antibody in synthetic media and in saliva or oropharyngeal swab samples was 0.
