-Highly significant differences are observed between the methyl derivatives of attapulgite, produced when this mineral is reacted with (CHz)zSi(OCzHs)2, in the presence or in absence of HCI. In the first case, the corresponding infrared spectra show characteristic absorption bands due to the Si(CH3)z radicals at 1260, 850 and 800cm -a as well as a shoulder at 960cm -t, the latter assigned to si...

Several cell types display binding sites for [~zSI]urokinase (Vassalli, J.-D., D. Baccino, D. Belin. 1985. J. Cell Biol. 100:86-92) which in certain cases are occupied with endogenous urokinase. These sites appear to focus urokinase at cell surfaces and hence may participate in tissue matrix destruction and cell invasion. Recently P611~inen et al. (1987) demonstrated that the cell surface uroki...

The anomuran crabs of the family Albuneidae Stimpson, 1858 are specialized forms, living buried in sand. Because of their preferred habitat, they are very rarely encountered, and thus have been poorly studied in general (Osawa & Fujita 2012). They are commonly called “Sand crabs” (Boyko 2002). Worldwide, the Albuneidae family currently includes 48 species belonging to nine genera (Boyko & McLau...

The influence of the first stars on the formation of second-generation objects at high redshift may be determined, in part, by their metal enrichment of surrounding gas. At a critical metallicity, Zcrit, primordial gas cools more efficiently by fine-structure lines of [C II] (157.74 μm), [O I] (63.18 μm, 145.5 μm), [Si II] (34.8 μm), and [Fe II] (25.99 μm, 35.35 μm) than by H I or H2 emission. ...

drought is a climatic phenomenon that causes much detrimental influence on ecological environments. this research investigates the performance of meteorological drought indices in different time scales in thetajan basin in iran. indices undergone in this study include: percent normal precipitation index (pnpi), z-score index (zsi), standard precipitation index (spi), china z index (czi), modifi...
