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...

Biglar Permo-Triassic bauxite deposit is located in ~15 km northwest of Abgarm, southwest of Ghazvin province, west of central Iran. It consists of 8 stratiform and discontinuous bauxite lenses lying along the contact of Ruteh (Permian) and Elika (Triassic) carbonate formations. Petrographically, the bauxite ores exhibit collomorphic-fluidal, pseudo-breccia, pseudo-porphyritic, panidio-morphic-...

For the past decades researchers are showing immense interest to investigate the natural advantage of preparation of composites from minerals such as bauxite particles, and proved their effectiveness as cost effective reinforcing agents in fabrication of high performance composites. This study, is a new attempt in using the Iraqi natural bauxite powder with different proportions (2wt%, 4wt%, an...

Each year, more than 25 percent of highway fatalities in the United States occur at or near horizontal curves, according to the Federal Highway Administration (FHWA). In an attempt to save lives and prevent injuries, some 30 states across the U.S. are applying high friction surfaces (HFS) to improve skid resistance at locations with a high incident of vehicle crashes such as severe horizontal c...

Congress mandated the establishment of the National Cave and Karst Research Institute in October 1998 to further the science of speleology by facilitating research, to enhance public education, and to promote environmentally sound cave and karst management. Considerable progress has been made during the tenure of the Interim Director (2000-2002) toward making the Institute operational. The scop...

This study aims to reveal the runoff variation characteristics of long time series in a karst region, analyse comprehensively its different driving factors, and estimate quantitatively the contribution rates of climate change and human activities to net runoff variation. Liudong river basin, a typical karst watershed in southwest China, is the study site. Statistical methods, such as linear fit...

Lithium is one of the secondary mineral elements occurring in bauxite. The behavior lithium-bearing bauxite digestion process was investigated, and effect conditions on extraction rates lithium studied. results demonstrate that mass ratio added CaO to bauxite, KOH concentration, temperature had a significant efficiency. An L9(34) orthogonal experiment demonstrated order each factor for from pri...

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...

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 ...
