Climate change is expected to introduce more water demand in the face of diminishing supplies, intensifying degree aridity observed terrestrial ecosystems 21st century. This study investigated spatiotemporal variability within global index (AI) values from 1970–2018. The results revealed an overall drying trend (0.0016 yr−1, p<0.01), with humid and semi-humid regions experiencing significant th...

Observations on heat-acclimatized men by Asmussen (1) and Williams and colleagues (2) showed no increase in cardiac output above the normal response during exercise in a hot, humid environment. Indeed, Asmussen found decrements in cardiac output below normal responses if moderate work in the heat (32° C, 80% relative humidity) was prolonged from 30 to 60 minutes. No systematic study has been re...

This study looked at the influence of inspired air water content on exercise-induced bronchospasm (EIB). On separate days, 12 mild asthmatics (4M, 8F), aged 18-39 yrs (mean: 27 yrs), performed four six minute steady-state exercises on ergometer at 80% of their maximum workload. Exercises were randomized to the following inspired air conditions: dry air (0% relative humidity (RH] during exercise...

Droughts significantly impact land carbon uptake by reducing the gross primary productivity (GPP). Projections suggest an increase in severe and extreme droughts twenty-first century. Despite importance of on uptakes, it remains unclear about GPP responses under different drought severity its changes current climate changes. Using four state-of-the-science products, we showed that moderate (−1 ...

The quantity of leachate is crucial when assessing pollution emanating from municipal landfills. In most cases, existing leachate quantification measures only take into account one source - precipitation, which resulted in serious underestimation in China due to its waste properties: high moisture contents. To overcome this problem, a new estimation method was established considering two source...

This paper aims to measure and analyze of the leakage current of 20 kV polymer and porcelain metal oxide surge arresters under humid ambient conditions by applying different voltages to the arresters terminal. The characteristics of the leakage currents at that stage have been investigated when changes in the ambient humidity were introduced in an artificial fog chamber. It is assumed that magn...

Tanzania 2002 Summary The continued vicious cycle of population-poverty-and-environmental degradation has been acknowledged. The purpose of this paper, therefore, is to draw attention to the serious consequences of land degradation, a national and trans-national socioeconomic complex problem, and the need for rehabilitating degraded lands in the sub-humid lands of Sub-Saharan Africa (SSA). The ...
