Organic fertilizers could be useful for agricultural sustainability. Therefore, this study explored green cultivation techniques to improve the grain yield of oilseed flax in dry areas Loess Plateau China. With no fertilization (CK) as control, effects sheep manure (S1: 12.5 t ha−1; S2: 25 ha−1), poultry (C1: 5.8 C2: 11.6 and chemical (F1: N 112 kg ha−1, P 75 K 67.5 F2: 225 150 135 ha−1) on gro...

Several combinatorial optimization problems can be approximated using algorithms based on semideenite programming. In many of these algorithms a semideenite relaxation of the underlying problem is solved yielding an optimal vector connguration v 1 : : : v n. This vector connguration is then rounded into a f0; 1g solution. We present a procedure called RP R 2 (Random Projection followed by Rando...

Application of the widely used Farquhar model of photosynthesis in interpretation of gas exchange data assumes that photosynthetic properties are homogeneous throughout the leaf. Previous studies showed that heterogeneity in stomatal conductance (g(s)) across a leaf could affect the shape of the measured leaf photosynthetic CO(2) uptake rate (A) versus intercellular CO(2) concentration (C(i)) r...

Etoricoxib, a potent and selective cyclooxygenase-2 inhibitor, was shown to be metabolized via 6'-methylhydroxylation (M2 formation) when incubated with NADPH-fortified human liver microsomes. In agreement with in vivo data, 1'-N'-oxidation was a relatively minor pathway. Over the etoricoxib concentration range studied (1-1300 microM), the rate of hydroxylation conformed to saturable Michaelis-...

The aim of this study was to investigate aerobic biodegradability of phenol, resorcinol and 5-methylresorcinol and their different two-component mixtures using activated sludge sampled from the Kohtla-Järve wastewater treatment plant. The degradation behaviour of phenolic compounds was investigated by respirometry. Non-linear regression analysis was used for determination of the kinetic paramet...

Cytochrome P4503A4 (CYP3A4) is the most abundant cytochrome P450 in adult human liver and small intestine and oxidizes numerous clinically, physiologically, and toxicologically important compounds. The metabolic activity of CYP3A4 in patients varies at least 10-fold in vivo, and CYP3A4 genetic variants are considered one of the causes of individual differences. The cDNAs for the CYP3A4(*)2 (S22...
