Coronavirus Disease 2019 (COVID-19): a new challenge in untreated wastewater
No full textCOVID-19 outbreak was declared a pandemic by the WHO on 12 March 2020. As of 27 May 2020, WHO statistics exhibited that more than five million confirmed cases have been reported globally. Much remains unclear about the fate and impact of SARS-CoV-2, the novel coronavirus 2019, in wastewater. SARS-CoV-2 infection, the etiologic agent of the current COVID-19 pandemic, is followed by virus shedding in the stool. The quantification of SARS-CoV-2 in wastewater, therefore, enables monitoring of the prevalence of infections among the population through wastewater-based epidemiology. This review discusses the possible spread of the SARS-CoV-2 virus in wastewater and its impact on human health, if any. The information and resources outlined in this paper are based on recently published studies and provide information to decision-makers on the successful management of COVID-19 and reduce the risk of human exposure to COVID-19. Additionally, systems-based approaches to curtail COVID-19 spread are also discussed.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Economic, Demographic, Deterrent Variables And Crime Rate In India
No full textCrime has plagued society since time immortal. The crime rate in India has been on rise, therefore, it becomes important to study the factors that impact the crime rate. The purpose of the paper is to investigate the relationship between various economic, demographic and deterrent factors and the crime rate in India. The study focuses on the extent of effects of various factors like population density, sex ratio, minority population, poverty, per capita income, no of police personnel and literacy rate on crime registered under IPC1 in all Indian states and major union territories. The study covers the data of all the Indian states and major union territories of period 2011. The findings show that these factors are crucial determinants of the rate of the criminal cases registered in India
Anchorage Capacity of Headed Bars in Steel Fiber Reinforced Concrete
No full textHeaded bars (HB) with different head shapes (Square, Circular, and Rectangular) and bar diameters (db: 16, 20, and 25 mm) embedded in steel fiber reinforced concrete have been subjected to pull-out test. The influence of head shapes, concrete compressive strength (M20 and M40), db, and steel fibers (0, 0.5, 1, and 1.5%) on the anchorage capacity of HB have been evaluated. Numerical model for improving the anchorage capacity of HB has also been proposed. Results have revealed that the anchorage capacity of HB increases with the increase in concrete compressive strength, db, and steel fibers, which have been validated by non-linear regression analysis using dummy variables. Two failure modes namely, steel and concrete-blowout have been observed and the prevailing mode of failure is steel failure. Based on load-deflection curves and derived descriptive equations, it is observed that the circular HB has displayed the highest peak load.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.
