The spectrin membrane skeleton is a ubiquitous cytoskeletal structure with several cellular roles, including the maintenance of cell integrity, determination of cell shape and as a contributor to cell polarity. We have isolated mutations in the gene encoding &bgr ;Heavy-spectrin in Drosophila, and have named this essential locus karst. karst mutant individuals have a pleiotropic phenotype chara...

Karst aquifers occur in a range of climatic and geologic settings. Nonetheless, they are commonly characterized by their vulnerability to water-quality impairment. Two karst aquifers, the Edwards aquifer in south-central Texas and the Upper Floridan aquifer in western Florida, were investigated to assess factors that control the movement of contaminants to public-supply wells (PSWs). The geoche...

Considering the important roles of carbonate rock fraction in karst rocky desertification areas and their potential for indicating damage to vegetation, improved knowledge is desired to assess the application of spectroscopy and remote sensing to characterizing and quantifying the biophysical constituents of karst landscapes. In this study, we examined the spectra of major surface constituents ...

The Moloney murine leukemia virus-transformed suspension cell line WMP2 is derived from wild mice (Mus musculus) of the WMP/WMP strain. These mice carry nine pairs of metacentric Robertsonian translocation chromosomes. As the chromosomes of the wild-type mouse are all acrocentric, metaphase spreads of the WMP2 cells seam to be highly suited for physical gene mapping. Here we studied the WMP2 li...

Few studies of monitoring rocky desertification based on Sentinel-2 MSI image with higher spatial and temporal resolutions have been reported. In this paper, nine typical surface parameters that derived from including three red edge indices introduced to establish two types feature space index: point-to-line type point-to-point type. The results show that: (1) index has a applicability in obtai...

Introduction. As a result of the conducted route reconnaissance and geological engineering surveys, data about development pattern exogenous processes at site adjoining city Ufa were obtained. This region is well studied due to extensively developed karst. Although landslides are less prevalent here, their frequently connected with karst intensification. Landslides, formed in sites sinkholes to...

The Nullarbor Plain is underlain by thick cratonic lithospheric mantle that almost devoid of contemporary seismicity. Analysis high-resolution digital elevation models indicates neotectonic fault-propagation fold traces on the nearly flat karst landscape locally extend to lengths >100 km, suggesting potential for hosting large (>7.3–7.5) moment magnitude earthquakes. Along-strike maximum displa...

In a mature karstic system, the realisation of galleries using the methodology of railway tunnel boring machine (TBM) involves particular problems due to the high risk of interference with groundwater (often subject to remarkable level variations) and with cavities and/or thick fill deposits. In order to define groundwater features it is necessary to investigate both hydrodynamic and karstifica...

By analysing the hydrographs of karst springs it is possible to identify aquifer characteristics and, accordingly, the main features of a karst rock-fissure massif. Consequently, relevant data can be obtained by analysing hydrograph recession curves. This paper presents a detailed analysis and explanation of numerous cases of break points on recession curves via various values of the recession ...
