Background and Aims: workers in petrochemical industries are exposed to various contaminants and are facing to serious hazards, therefore a comprehensive risk assessment program for identification of hazardous chemicals that affect human health and also determination of hazardous tasks and processes is necessary. Methods : This descriptive cross-sectional study was conducted
Hurricanes are complex systems that carry large amounts of energy. Their impact often produces natural disasters involving the loss of human lives and materials, such as infrastructure, valued at billions of US dollars. However, not everything about hurricanes is negative, as hurricanes are the main source of rainwater for the regions where they
Lyophilized aqueous extracts of four underutilized fruit species namelyDiospyros discolor (Velvet apple), Pouteria campechiana (Lavulu/Canistel), Phylanthusacidus (Mal-Nelli/Star gooseberry) and Phyllanthus emblica (Nelli/Indian gooseberry) were investigated for the antioxidant potential (AP) by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, 2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay and ferrousreducing antioxidant power (FRAP) assay. Total phenolic content (TPC) and total monomeric anthocyanin content
Very massive stars occasionally expel material in colossal eruptions, driven by continuum radiation pressure rather than blast waves. Some of them rival supernovae in total radiative output, and the mass loss is crucial for subsequent evolution. Some are supernova impostors, including SN precursor outbursts, while others are true SN events shrouded by material
Background: Rosa damascena L. is the most notable species of the Rosaceae family in the world, and has been used in food, cosmetics, and the pharmaceutical industry. Bioactive compounds in this flower are known to have several activities, such as antioxidant, antimicrobial, and anti-inflammatory. In this study, the antioxidant and collagenase inhibitory activities of R. damascena L.
Almost percent of U.S. voters will be able to vote by mail in the presidential election, The New York Times reported on Tuesday. The highest percentage of Americans in U.S. history will automatically be eligible for mail-in voting without an excuse, as several states have adjusted their election systems amid the coronavirus pandemic.
Monday’s arrests underscored the speed with which the former British colony’s political freedoms — including rights to assembly and freedom of the press — are being curtailed by Beijing. “Taken together, the dramatic events quashed any doubt that Beijing would use the national security law as a mere deterrent and underscored the increasingly
Abstract Background Coronavirus disease 2019 (COVID-19), caused by a novel corinavirus (later named SARS-CoV-2 virus), was fistly reported in Wuhan, Hubei Province, China towards the end of 2019. Large-scale spread within China and internationally led the World Health Organization to declare a Public Health Emergency of International Concern on 30th January 2020. The clinical
Bystanders look at MV Wakashio bulk carrier that had run aground and from which oil is leaking near Blue Bay Marine Park in south-east Mauritius on August , . The Indian Ocean island of Mauritius declared a state of environmental emergency late Friday after a Japanese-owned ship that ran aground offshore days ago
Natural and anthropogenic hazards are frequently responsible for disaster events, leading to damaged physical infrastructure, which can result in loss of electrical power for affected locations. Remotely-sensed, nighttime satellite imagery from the Suomi National Polar-orbiting Partnership (Suomi-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) can monitor power outages in disaster-affected areas
