The associations between time spent in sleep, sedentary behaviors (SB) and physical activity with health are usually studied without taking into account that time is finite during the day, so time spent in each of these behaviors are codependent. Therefore, little is known about the combined effect of time spent in sleep, SB and physical activity, that together constitute a composite whole, on obesity and cardio-metabolic health markers.

Antigens encoded by the var gene family are major virulence factors of the human malaria parasite Plasmodium falciparum, exhibiting enormous intra- and interstrain diversity. Here we use network analysis to show that var architecture and mosaicism are conserved at multiple levels across the Laverania subgenus, based on var-like sequences from eight single-species and three multi-species Plasmodium infections of wild-living or sanctuary African apes.

How rainfall arrives, in terms of its frequency, intensity and the timing and duration of rainy season, may have a large influence on rainfed agriculture. However, a thorough assessment of these effects is largely missing. This study combines a new synthetic rainfall model and two independently-validated crop models (APSIM and SARRA-H) to assess sorghum yield response to possible shifts in seasonal rainfall characteristics in West Africa.

The formation of new crossbred cattle breeds to increase milk production was started in India because of crossbred cattle were more economical and gave higher milk yield than the indigenous cows and increase the income of a farmers, dairy entrepreneurs and provide beneficial and round the year employment to them. Therefore, population of crossbred cows should be increased simultaneously with Artificial Insemination programme to increase profitability to the farmers and dairy industry.

Growing food in unconventional systems such as those using irrigation with domestic wastewater and the use of potentially toxic waste has generated resistance from producers and consumers. Here, we evaluate the possible physical and biochemical damage to Swiss mice fed for 13 weeks with corn produced in soil containing tannery sludge vermicompost and irrigated with wastewater from domestic sewage.

The present article discusses the application of a new technology using solar photovoltaic (PV) cell coupled with membrane distillation (MD) in the desalination of tap water. Salinity decreases the palatibility of water and causes long-term health issues. MD is the most promising technology to provide safe and clean drinking water to households and for other applications in small quantities. It consumes less energy than the existing commercial brackish water reverse osmosis (RO; pressure-driven) desalination technology (48%) used for the production of drinking water.

Carbon farming describes a collection of eco-friendly techniques that have the ability to increase carbon sink into soil, i.e. carbon sequestration. Increasing C sink in the soil will help reduce the amount of CO2, CH4 and N2O emissions in the environment. Carbon farming that leads to reduction in greenhouse gas (GHG) emissions is referred to as abatement activities. It holds carbon in vegetation and soils, and reduces GHG emissions. (Correspondence)

Diesel exhaust is a known lung carcinogen. Farmers use a variety of dieselized equipment and thus may be at increased risk of lung cancer, but farm exposures such as endotoxins may also be protective for lung cancer. The researchers evaluated the relative risk of incident lung cancer, including histological subtype, from enrollment (1993-1997) to 2010-2011 in relation to farm equipment use in the Agricultural Health Study (AHS), a prospective cohort study of pesticide applicators and spouses in Iowa and North Carolina, USA.

The spatial and temporal characteristics in the frequencies of four types of high-impact weathers (HIWs), i.e. snowfall, thunderstorm, foggy and hailstorm weathers were analyzed in China by using daily weather phenomenon data from 604 stations. Results indicate that snowfall, thunderstorm, foggy and hailstorm days showed significant decreasing trends with rates of 2.5, 2.6, 0.8 and 0.5 days per decade respectively, and snowfall, thunderstorm, foggy and hailstorm weather processes decreased significantly at rates of 0.3, 0.4, 0.1 and 0.1 times per decade during 1959–2014.
