China is a country with significant but unevenly distributed water resources. The water stressed North stays in contrast to the water abundant and polluted South defining China's current water environment. In this paper we use the latest available data sets and adopt structural decomposition analysis for the years 1992 to 2007 to investigate the driving forces behind the emerging water crisis i...

Traditionally, people have inhabited places with ready access to fresh water. Today, over 50% of the global population lives in urban areas, and water can be directed via tens of kilometres of pipelines. Still, however, a large part of the world's population is directly dependent on access to natural freshwater sources. So how are inhabited places related to the location of freshwater bodies to...

Water rendering is one of the most computationally demanding task in computer graphics. Because of its computational complexity, real-time water rendering requires high-end hardwares. In this paper, we present a new algorithm for real-time rendering of large bodies of water such as open seas and oceans which results in an improved efficiency. Using interactive frustum, water surface can be flui...

Mapping of natural and man-made water bodies is a critical component of environmental studies, including climate change, agriculture, flood forecasting and groundwater recharge estimation. Moreover, standing water heavily impacts the ability to accurately estimate soil moisture from satellite, particularly from low resolution passive microwave data using a radiometer. NASA’s soil moisture dedic...

Water is the most important substance on Earth. While not a mineral itself, water rules the mineral kingdom since interaction with water is fundamental to all geological processes. And water can even slip into the mineral kingdom by freezing into ice. Water occurs in the hydrologic cycle as soil water, groundwater and surface water. We also find water vapor in the atmosphere and frozen water in...

In the face of plans for increased construction of dams and reservoirs in the Mekong River Basin, it is critically important to better understand the primary-producer community of phytoplankton, especially the warm-water cyanobacteria. This is because these algae can serve as the primary source of carbon for higher trophic levels, including fishes, but can also form harmful blooms, threatening ...

Nodularin (NOD) is a cyclic penta-peptide hepatotoxin mainly produced by Nodularia spumigena, reported from the brackish water bodies of various parts of the world. It can accumulate in the food chain and, for safety reasons, levels of NOD not only in water bodies but also in food matrices are of interest. Here, we report on a non-competitive immunoassay for the specific detection of NOD. A pha...

The infraorder Gerromorpha comprises semiaquatic bugs, most of which spend much of their lifetime on the water surface, between floating plants, or on the margins of water bodies. Based on literature and collections made on streams and lakes on municipalities of eastern Mato Grosso, Brazil, a list has been elaborated with 52 species, including several new records. Out of the recorded species, 2...
