.soil microorganisms are important agents in nutrient cycling and energy flow. they are extremely sensitive to environmental changes. soil microbial biomass has been proposed as an index of soil stress and disturbance. the objective of this study was to determine the effects of barley (hordeum vulgare l.) residue amounts, burning, nitrogen fertilizer levels and tillage management on organic car...

Research on people's motives for engaging in high-risk activities has typically been viewed through the single-focused lens of sensation seeking. We provide evidence that comprehensively challenges that view. First, we develop and confirm the structure of a 3-factor measure of motives: the Sensation Seeking, Emotion Regulation, and Agency Scale (SEAS; Study 1). We then use the SEAS to provide e...

A Hindu male, unmarried, pujari by profession, was admitted into the Thomason Hospital, Agra, on 13th September, 1941, with the-following complaints :? (i) Pigmentation of the skin all over the body. (ii) Burning sensation all over the body. The patient stated that three years back he noticed a black patch on the palm of the right hand which slowly extended above the wrist. Within two years all...

Climate change has increased the area affected by forest fires each year in boreal North America1,2. Increases in burned area and fire frequency are expected to stimulate boreal carbon losses3–5. However, the impact of wildfires on carbon emissions is also affected by the severity of burning. How climate change influences the severity of biomass burning has proved difficult to assess. Here, we ...

Indoor air particulate (PM) exposure is several folds more dangerous than  outdoor air  owing to burning of different materials. Burning biomass emits toxic fumes that are found to be associated with  numerous health problems  such as respiratory diseases, etc. In our study area,  approximately 80% of the population of Chhattisgarh state, central India use biomass  such as wood, and cow dung as...

BACKGROUND An epidemic of carbon monoxide poisoning suicide by burning barbecue charcoal has occurred in East Asia in the last decade. We investigated the spatial and temporal evolution of the epidemic to assess its impact on the epidemiology of suicide in Taiwan. METHODS AND FINDINGS Age-standardised rates of suicide and undetermined death by charcoal burning were mapped across townships (me...

The HadGEM2 earth system climate model was used to assess the impact of biomass burning on surface ozone concentrations over the Amazon forest and its impact on vegetation, under present-day climate conditions. Here we consider biomass burning emissions from wildfires, deforestation fires, agricultural forest burning, and residential and commercial combustion. Simulated surface ozone concentrat...

We present a numerical study of the effects of carrier diffusion and spatial hole-burning in vertical-cavity surfaceemitting lasers under gain switching. Our model includes spatial and temporal dependences of both the optical field and the carrier density. Results show that spatial hole burning places a limit on the minimum achievable pulse width. We demonstrate that spatial hole-burning can be...
