Formation of inclusion complexes of monochlorotriazinyl-β-cyclodextrin with promethazine was studied, for establishing the optimal conditions of their formation, in view of subsequent grafting on cellulose textiles with potential medicinal use. The infrared spectral study of inclusion in solid state indicated that the complex can be even formed by physically mixing the two substances. By the co...

This paper presents new ideas about the formational identity, as well first data on age of formation rocks within Lysan intrusive complex located at junction Derbin block and Sisim-Kazyr zone Central Asian folded belt. The study identified similarities between intrusions alkaline-ultrabasic formation. It formed during period maximum intraplate activity along edge Siberian craton.

The L-form NC7, derived from Escherichia coli K12, grew in a complex medium containing 0.2 M-CaCl2 as osmotic stabilizer, but not at pH values above 7.8. The cessation of growth at alkaline pH was not due to cell death. In complex media containing K+ or Na+, the L-form grew ove a wide pH range. Growth at alkaline pH was inhibited by 1 mM-amiloride, indicating that Na+/H+ antiport activity was r...

Iron is an essential nutrient for all plants. However, terrestrial plants often suffer from iron deficiency in alkaline soil due to its extremely low solubility. Alkaline soil accounts for about 30% of all cultivated ground in the world. Plants have evolved two distinct strategies, I and II, for iron uptake from the soil. Dicots and non-graminaceous monocots use Strategy I, which is primarily b...
