Mobilization of As from geological materials into ground and drinking water sources may represent an important threat to human health. The objective of this study was to assess the As concentration and availability in underground water used as drinking water sources. Water samples were collected from public and private wells in Timis-Bega area of Pannonian Basin, West Romania. Total-dissolved A...

Cuatro Cienegas basin (CCB) is a biodiversity reservoir within the Chihuahuan desert that includes several water systems subject to marked seasonality. While several studies have focused on biodiversity inventories, this is the first study that describes seasonal changes in diversity within the basin. We sampled Pseudomonas populations from a seasonally variable water system at four different s...

Several programs have been written to process laser scan data from two shoals in the Netherlands. The first makes a grid of heights, the second calculates deformations and makes plots. The third utilises a variogram to obtain information about the amplitude, direction and wavelength of tidal ripples, which are processed and plotted by a fourth program. Six scans have been made in order to compa...

Basin morphometry is a means of numerically analysing or mathematically quantifying different aspects of a drainage basin. In the present study, morphometric analysis of the Baitarani basin has been carried out using earth observation data and geographical information system (GIS) techniques. The morphometric parameters considered for analyses include the linear, areal and relief aspects of the...

Using THEMIS, MOC and MOLA data, we have found 120 craters in the diameter range 6 11.2 km that have unusually high depth/diameter (d/D) ratios (i.e., 0.0012) within southwestern Utopia Planitia and Isidis Planitia, Mars (Figure 1). Previous studies [1, 2, 3] noted a concentration of deep simple craters located mainly in SW Utopia Planitia suggesting that the deep simple craters could be caused...

The S ile Region contains discontinuous, cyclic, thin coal beds and industrial clay deposits that were accumulated in lacustrine basins which received extensive volcanoclastic sediments due to transport of highly weathered calc-alkaline volcanic rocks. The Sülüklü area has the largest kaolin deposit in this region. Cyclic kaolinization depended on the degree of leaching of Si and alkalis in cyc...

A digital terrain model (1000-m effective spatial resolution) of the Caloris basin, the largest well-characterized impact basin on Mercury, was produced from 208 stereo images obtained by the MESSENGER narrow-angle camera. The basin rim is far from uniform and is characterized by rugged terrain or knobby plains, often disrupted by craters and radial troughs. In some sectors, the rim is represen...
