Most of the detected and quantified microplastics were confirmed as they are from secondary sources. Most of the microplastic pollution research was conducted dominantly in South Africa, and secondly Nigeria, although other countries should also start conducting in their water systems. Surface water and...
performance7,8,9,10,11. Cooler–condenser devices use work (typically electric energy) to actively cool air below its dew point and collect condensation and—if solar-driven—call for photovoltaic (PV) panels. Unlike solar–thermal devices, solar-driven cooler–condenser devices suffer from a ste...
An Ethiopian primary school pupil gets clean water from an air-water generator donated by Chinese organizations in Southern Nations, Nationalities and Peoples' Region, Ethiopia, on June 22, 2022. Chinese organizations have distributed much-needed clean and sanitary water facilities to selected primary ...
Here we present a bold departure from existing approaches by establishing the viability of significantly increasing freshwater through the capture of humid air over oceans. We show that the atmosphere above the oceans proximal to the land can yield substantial freshwater, sufficient to support large ...
As a result, farmers have shifted towards diesel pumping, which brings problems of air pollution and diesel supply. The subsidies have discouraged farmers from considering alternative cropping systems, or growing high value crops using less water and energy which are capable of generating higher ...
The total and eddy transport of water vapour are derived from 1967 upper-air data at South African aerological stations. Broad features of the transport fields are given as well as a brief comparative analysis of water vapour studies. It is shown that the transport of vapour over Southern ...
Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are inwaternearly that deep, but statistics say they're still likely to turn up. 出自-2010年6月阅读原文 Donna helped the people of the village to organize an irrigation project, and she also ...
the mean air temperature is 7.8–13.5 °C, mean annual precipitation is between 400–800 mm (decreasing from south to north), mean potential evapotranspiration is 800–1100 mm (decreasing from east to west), and mean runoff is 195 m3/s [31]. The Wei River has two main tributaries on th...
(3) We use the UTrack dataset to calculate P after restoration on the basis of the increase in E calculated from steps 1 and 2. (4) We use Budyko models to calculate E and Q after restoration with evaporation recycling. The calculation of E and Q without evaporation recycling (step 2)...
Water hyacinth is a free-floating and flowering invasive aquatic plant originated from Amazon Basin, South America. It has spread mainly to the tropics and subtropics since the 1800s. Water hyacinth has been considered as an invasive aquatic plant in the United States since 1984, in Africa since...
