25, 99%CI=1.07-1.46, p=0.0003), less expensive (AOR=1.20, 99%CI=1.07-1.35, p<0.0001), more convenient to buy (AOR=1.36, 99%CI=1.13-1.62, p<0.0001) and safer to purchase (AOR=1.21, 99%CI=1.02-1.44, p=0.0047). With the notable exception of price, consumers reported generally positive perceptions of the legal cannabis market, with more positive perceptions in US states with more 'mature' legal markets.With the notable exception of price, consumers reported generally positive perceptions of the legal cannabis market, with more positive perceptions in US states with more 'mature' legal markets.Correlational research suggests that emotion regulation deficits, which are known risk factors for substance addictions, may also play a role in the development of problem behaviors such as excessive or maladaptive use of social networking sites (SNS). This study sought to experimentally assess the hypothesized emotion regulatory function of SNS use. 139 undergraduates (53.2% female) were randomized to view brief movie clips known to reliably induce positive (37.4%), negative (29.5%), or neutral mood (33.1%) and then to browse a SNS (46.8%) or control website (53.2%). Mood and subjective urge to access SNS and the Internet were assessed before and after viewing the movie clips and browsing the websites. Participants meeting criteria for "moderate" levels of disordered SNS use self-reported significantly greater deficits in emotion regulation (p = .02, ηp2 = 0.14). Increases in positive and negative affect following the mood induction were associated with a decrease in subjective urge to access SNS (r = -0.22, p = .02, r = -0.28, p = .002, respectively). Time spent browsing SNS resulted in significantly greater increases in self-reported positive affect, compared to the control website (p = .001, ηp2 = 0.09). We replicate previous findings of greater emotion regulation deficits in individuals endorsing problematic SNS use. Increased positive and negative affect resulted in decreased urge to access SNS, suggesting that social networking may primarily serve to counter low-arousal emotions like boredom. Data provide initial experimental evidence to support the hypothesized emotion regulatory function of SNS, with SNS exposure resulting in increased positive affect. Findings suggest that interventions targeting problematic SNS use should incorporate strategies for improved emotion regulation.To develop an economic and sustainable biochar application strategy for mitigating methane emission from paddy fields, a four-year field experiment was conducted to compare two biochar amendment methods. The annual low (AL) rate pyrolyzed biochar returning method used the same amount of biochar as was harvested from rice straw in the field, 2.8 t ha-1 yr-1. The high single (HS) biochar returning method consisted of a single application of 22.5 t ha-1 biochar only in the first year, 2015. Our results showed that the AL biochar returning strategy prevailed over the HS strategy in mitigating methane emission from paddy fields. On average, AL and HS could reduce methane emissions by 41% and 38.25% in four years, respectively. Methane accumulation per unit rice production was 45.8% and 43.1% in AL and HS, respectively. AL showed a stable effect on mitigating methane emission over four successive years, which resulted from the continuously increasing methanotrophs due to annual fresh biochar application. Aged biochar weakened the promotion of methanotrophs, leading to lower methane reduction rates in HS than in AL in the 4 years. Our results indicate that AL is a highly sustainable strategy for methane mitigation in paddy fields due to its high efficiency, practical operation, and economical acceptance.We made the first ever successful effort in India to detect the genetic material of SARS-CoV-2 viruses to understand the capability and application of wastewater-based epidemiology (WBE) surveillance in India. Sampling was carried out on 8 and 27 May 2020 at the Old Pirana Waste Water Treatment Plant (WWTP) at Ahmedabad, Gujarat that receives effluent from Civil Hospital treating COVID-19 patients. All three, i.e. selleck chemicals llc ORF1ab, N and S genes of SARS-CoV-2, were found in the influent with no genes detected in effluent collected on 8 and 27 May 2020. Increase in SARS-CoV-2 genetic loading in the wastewater between 8 and 27 May 2020 samples concurred with corresponding increase in the number of active COVID-19 patients in the city. The number of gene copies was comparable to that reported in untreated wastewaters of Australia, China and Turkey and lower than that of the USA, France and Spain. However, temporal changes in SARS-CoV-2 RNA concentrations need to be substantiated further from the perspectives of daily and short-term changes of SARS-CoV-2 in wastewater through long-term monitoring. The study results SARS-CoV-2 will assist concerned authorities and policymakers to formulate and/or upgrade COVID-19 surveillance to have a more explicit picture of the pandemic curve. While infectivity of SARS-CoV-2 through the excreted viral genetic material in the aquatic environment is still being debated, the presence and detection of genes in wastewater systems makes a strong case for the environmental surveillance of the COVID-19 pandemic.The COVID-19 pandemic has triggered an industrial and financial slowdown due to unprecedented regulations imposed with the purpose to contain the spread of the virus. Consequently, the positive effect on the environment has been witnessed. One of the most prominent evidences has been the drastic air quality improvement, as a direct consequence of lower emissions from reduced industrial activity. While several studies have demonstrated the validity of this hypothesis in mega-cities worldwide, it is still an unsubstantiated fact whether the same holds true for cities with a smaller urban extent and population. In the present study we investigate the temporal development of atmospheric constituent concentrations as retrieved concurrently from the Sentinel-5P satellite and a ground meteorological station. We focus on the period before and during the COVID-19 pandemic over the city of Hat Yai, Thailand and present the effect of the lockdown on the atmospheric quality over this average populated city (156,000 inhabitants).
