classes in N(p,q). We show that X(p,q) with the quotient topology is homeomorphic to the compact, connected quotient space G(p, so(q,Â)) / SL(q,Â), where SL(q,Â) acts on so(q,Â) and the associated Grassmann manifold G(p, so(q,Â)) by g(Z) = gZgt for Z ∈ so(q,Â) and g ∈ SL(q,Â). It follows immediately that X(p,q) is homeomorphic to X(D−p,q), where D = dim so(q,Â) = (1/2)q(q−1) (duality). For each...

INTRODUCTION We have previously reported results of precipitation studies for neonatal parenteral nutrition solutions containing calcium chloride and sodium phosphate using visual methods to determine compatibility. The purpose of this study was to do further testing of compatibility for solutions containing calcium chloride using more sensitive methods. METHODS Solutions of Trophamine (Braun...

Epidemiological studies have shown an association between consump tion of alcoholic beverages and increased occurrence of large bowel carcinoma, but studies in experimental models of colonie carcinogenesis have produced conflicting results. We assessed the effects of chronic dietary ethanol consumption during the preinduction and induction phase (period of acclimatization and carcinogen adminis...

The use of polyethylene glycol (PEG) for precipitation of DNA has been described in the literature (1-6) . We present here conditions for precipitation of DNA by PEG that give improved recoveries of DNA so that precipitation by PEG is comparable to that by ethanol, in terms of recovery, over a wide range of DNA concentrations. The problem of precipitation of lowmolecular-weight DNA fragments by...

This article will explore in detail the concept between Uzbek and Korean, characteristics of comparisons, which are representative types figurative expression, process expanding vocabulary meaning words to meanings comparisons. Figurative expression means a deviation from laws everyday language it shows appearance connection dictionary metaphorical based on their forms or similarities attribute...

The mechanism of uptake of Adriamycin was investigated in chick embryo heart and liver cells and in murine L5178Y lymphoblasts in vitro. Drug uptake at 4°C for 15 s due to rapid association accounted for a celhmedium distribution ratio of 104 ±14 (SE) in heart cells, 10.2 ±1.3 in liver cells, and 10.3 ±1.5 in L5178Y lymphoblasts. On thin-layer Chromatographie analysis, 98% of the radioactiv...

Membrane based treatment processes are very effective in removing salt from wastewater, but are hindered by calcium scale deposit formation. This study investigates the feasibility of removing calcium from treated sewage wastewater using accelerated seeded precipitation. The rate of calcium removal was measured during bench scale batch mode seeded precipitation experiments at pH 9.5 using vario...

BL6 melanoma cells injected s.c. in 18-month C57 BL/6 mice elicit a markedly fibrotic response similar in myofibroblast and collagen com position to that characterizing the desmoplastic response of human breast carcinoma. This host response can be quantitated by measuring hydroxyproline (total collagen) and incorporation of i.p.-injected [uC]proline into collagenase-sensitive protein (new colla...
