We recently reported that the high mannose-type oligosaccharides of the biosynthetic intermediates of &glucuronidase contain phosphate groups in diester linkage between mannose residues and outer a-linked N-acetylglucosamine residues (Tabas, I., and Kornfeld, S. (1980) J. Bwl. C h m . 255, 6633-6639). We now describe an a-N-acetylglucosaminyl phosphodiesterase from rat liver that is capable of ...

In this study, the isothermal reduction of iron oxide pellets, made of Iranian Chadormalo, Gole-gohar, and Sangan iron ores, was investigated in the temperature range of 900-1100°C. Tabas, Pabdana, Babnizoo, Karmozd, and Shahrood domestic coals were used as reductants. Parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...

Optimizing the operational parameters of borehole pattern in coal seam includes maximum amount gas to be drained with least drilling, investment, and drainage time. The main purpose this research is properly design C1 Tabas mine. In research, Comsol Multiphysics software was used for numerical modeling boreholes. According method diffusion methane a seam, reduction concentration released from b...

the maxillary first premolar may present large number of anatomic variations. the clinician should be aware of the configuration of the pulp system. maxillary first premolars usually have two canals. the incidence of three canals in these teeth is quite rare. this case report presents the diagnosis and clinical management of a maxillary first premolar with two distinct canals in the apical thir...

a simple, rapid and sensitive spectrophotometric method has been proposed for the determinationof vanadium (iv). the method is based on the catalytic effect of v (iv) on the oxidation of alkali blue bypotassium bromate at ph 4. the rate of decrease in the absorbance of alkali blue (at 572 nm) wasproportional to the concentration of v (iv) in the range of 100-6000 ng ml-1. the detection limit wa...
