In the present study, the possibility of concentrating tungsten-copper vein ore in South Chah-Palang was examined using gravity separators including Jig Machine (-2360+600 μm), shaking table (-600+120 μm), and multi-gravity separator (MGS) (-120 μm). The representative sample contains 1.5% WO3 and 5.95% CuO. The main tungsten minerals were ferberite and wolframite and their appropriate liberati...

a detailed study of the lower cretaceous dasyclad algae of the shahkuh formation was done in the chahpalang stratigraphic section (its name comes from the mountain in studied area). according to the study of the 101 thin sections, for the first time, we recognized 7 genus and 8 species of dasyclad algae from shah kuh formation in chah palang section including angioporella cf. fouryae, griphopor...

Migrating embryonic cells have high levels of cell surface galactosyltransferase (GalTase) activity. It has been proposed that GalTase participates during migration by recognizing and binding to terminal N-acetylglucosamine (GlcNAc) residues on glycoconjugates within the extracellular matrix (Shur, B. D., 1982, Dev. Biol. 91:149-162). We tested this hypothesis using migrating neural crest cells...

Neurite outgrowth from PC12 pheochromocytoma cells, as well as from peripheral and central nervous system neurons in vitro, is mediated by the extracellular matrix molecule, laminin. We have recently shown that mesenchymal cell spreading and migration on laminin is mediated, in part, by the cell surface enzyme, beta 1,4 galactosyltransferase (GalTase). GalTase is localized on lamellipodia of mi...

Livestock grazing is one of the most important kinds of land usage that has a high potential to decrease or increase carbon storage in rangeland ecosystem. This research was investigated the effects of enclosure on soil carbon storage in a rangeland with dominant plants of Artemisia aucheri. Hence, two rangelands of enclosure (Shahtappeh-Chah Mahmood) and no enclosure (Chiro) were chosen in Sem...

One of the major strengths of a Geographic Information System (GIS) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. These capabilities make GIS an extremely useful tool for mineral exploration. Several spatial modeling techniques can be employed to produce potential maps. However, these...

Albu, Jeanine B., Michael Curi, Meredith Shur, Laura Murphy, Dwight E. Matthews, and F. Xavier Pi-Sunyer. Systemic resistance to the antilipolytic effect of insulin in black and white women with visceral obesity. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E551–E560, 1999.—This study was designed to determine the role of visceral adipose tissue (VAT) accumulation in systemic fat metabolism and...

although in most of the rural development plans, relocation of informal settlements is oftenconsidered as an efficient solution to increase safety of rural communities against natural and man-made disasters,such as, earthquakes, fire hazards, floods, etc. an evaluation of recent experiences in the relocation projects show thatthe relocated community is often unsatisfied with the new residential...
