Abstract The European Water Framework Directive demands to assess and report the chemical ecological status of water bodies (WB). Linking their drivers pressures deriving suitable mitigation measures require knowledge shape area WB catchments. We derived a network 26 570 catchments in Germany using hydrologically‐defined drainage basins German federal states. established 338 149 basins. This un...

Simulating large amounts of water in real time is often achieved using heightfield methods. Allowing the water to interact with rigid bodies is essential for applications such as games, but traditional heightfield interaction methods concentrate on water-tobody effects by letting water flow through the bodies. We instead take an approach where the bodies block water. Our earlier method is impro...

Bacteriological characteristics of abattoir effluents (wastewater), abattoir water source, and water bodies receiving abattoir wastewater were investigated in Abuja, Nigeria using the multiple-tube fermentation technique. Source of water to the abattoirs and the usage of water bodies receiving abattoir effluents were determined using questionnaires. Bacterial counts ranged from 4.8 × 10(6) to 5...

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...

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 ...

Although several studies have associated Mycobacterium ulcerans (MU) infection, Buruli ulcer (BU), with slow moving water bodies, there is still no definite mode of transmission. Ecological and transmission studies suggest Variable Number Tandem Repeat (VNTR) typing as a useful tool to differentiate MU strains from other Mycolactone Producing Mycobacteria (MPM). Deciphering the genetic relatedn...

Water bodies and water systems are essential for survival and protecting them against terrorist threats like biochemical warfare agents and against threats from toxic industrial chemicals is of at most importance. This paper will examine the issues in protecting water bodies and water systems against waterborne biochemical warfare. We will also present preliminary ideas on a sensor network-base...

Monitoring open water bodies accurately is an important and basic application in remote sensing. Various water body mapping approaches have been developed to extract water bodies from multispectral images. The method based on the spectral water index, especially the Modified Normalized Difference Water Index (MDNWI) calculated from the green and Shortwave-Infrared (SWIR) bands, is one of the mo...

Overview: Some workers have proposed that large Martian basins contained extensive water bodies in the past, and have hypothesized that an ancient ocean extended over much or all of the northern lowland plains. With considerable depths over large areas, these water bodies would have represented massive surficial loads. The irregular form of some Martian basins, as well as spatial inhomogeneitie...

Two intersting cases of foreign bodies ingestion reported. First case who was a mentaly depressed, ingested many needles and bistoury blades. Few of them were fixed in patient's Meckel Diverticulum. A lot of foreign bodies removed by simple extraction transmurally or gastrotomy or intestinal resection. A few of them passed spontaneously by stool. Second case commiting suicide ingested chalky wa...
