It is undeniable that there a wide variety of pollutants in the various water bodies around planet, including organic and inorganic compounds, pathogenic microorganisms, microplastics [...]

The objective of this study is to conduct a comprehensive assessment of the transport of isoxaflutole and RPA 202248 and their accumulation potential in semistatic water bodies, using a distributed watershed scale model and observed water quality data. A conceptual model was developed to characterize the fate and transport of isoxaflutole residues to and in surface water. The soil and water ass...

Water bodies are essential to humans and other forms of life. Identification of water bodies can be useful in various ways, including estimation of water availability, demarcation of flooded regions, change detection, and so on. In past decades, Landsat satellite sensors have been used for land use classification and water body identification. Due to the introduction of a New Operational Land I...

Surface water is used for a variety of purposes like drinking, washing, bathing, recreation as well as numerous other varied industrial applications. The wholesomeness of these surface waters has become an issue of great concern. Water pollution is a burning issue all over the world. In recent years an increasing awareness has developed on the impact of human activities on the environment becau...

liquid at room temperature. It tends to form perfectly shaped minute spheres when in contact with air or water because of its high surface tension. Due to such a physical property, the injection of mercury into soft tissue produces a characteristic radiographic appearance. We report a case of mercury foreign bodies within the soft tissue of the arm with imaging findings, including MRI findings.

Proton nuclear magnetic resonance (NMR) imaging previously has been used to examine structure and pathologies of the eye. The present study investigates the use of a saturation-transfer technique, which exploits water-macromolecular proton magnetic interactions, to enhance image contrast in the rabbit eye in vivo. Upon steady-state saturation of the macromolecular-proton magnetization, the wate...

Introduction Thousands of chemical substances, including toxic, persistent, bioaccumulative substances (TPBS), are produced and used world-wide annually 1 . These volatile and semivolatile TPBS may be transported by air both in gaseous phase and adsorbed to atmospheric particles 2 prior to deposition in soil and water. Due to the grasshopper effect, TPBS released may evaporate in warmer climate...

This paper presents a novel geodesic active contour (GAC) model based on an edge detector for rapid detection of water bodies from spaceborne synthetic aperture radar (SAR) imagery with high speckle noise. The original edge indicator function based on gradients is replaced by an edge indicator function based on the ratio of exponentially weighted averages (ROEWA) operator. Thus, the capability ...
