Fatty Acids, α-tocopherol, β-caroten, minerals, and some pomological properties of walnut genotypes from four locations (Iğdır, Tuzluca, Karakoyunlu, Kağızman) of Aras Valley (Eastern Turkey) were examined. In this study, the differences among the genotypes were determined in terms of some fruit characteristics, oil and protein contents, fatty acid composition, selenium content, α-tocophero...

The interaction between eriochrome black T and Li , Na , K ,Mg and Ca ions in acetone and dimethylsulphoxide solutions has been investigated spectrophotometrically. The formation constants of the resulting 1 : 1 complexes were determined and found to decrease in the order Mg >Ca >Li >K >Na in both solvents used. There is an inverse relationship between the stabilities of the complexes...

Background: The effects of aqueous extract of Fadogia agrestis stem at the doses of 18, 36, and 72 mg/kg body weight on alloxan-induced toxicity was investigated in Wistar rats. Methods: In total, 35 rats of both sexes (132.80±7.22g) were randomized into five groups (A-E): animals in group A received 0.5 ml of distilled water orally on daily basis for 15 days while the alloxanized rats in gr...

The effects of chemotherapy [25 mg/kg 1,3-bis(2-chloroethyl)-1-nitrosourea administered with a single i.p. injection] on cellular energetics by P nuclear magnetic resonance (NMR) spectroscopy, total tissue sodium by single-quantum (SQ) Na NMR spectroscopy, and intracellular sodium by triple-quantum-filtered (TQF) Na NMR spectroscopy were studied in the s.c. 9L glioma. Animals were studied by NM...

Total Mg content in plasma and erythrocytes did not significantly differ between WKY and SHR. Mg efflux via Na/Mg antiport was 10% lower in non Mg-loaded erythrocytes of SHR than in WKY, and 16% lower in Mg-loaded erythrocytes of SHR. The activation of Na/Mg antiport in erythrocytes by Cl, as tested by substitution of Cl with SCN, and the regulation of Na/Mg antiport by protein kinases, as test...

ABSTRACT- Seed germination and early seedling growth are critical stages for plants establishment and production, particularly under salinity conditions. Exogenous application of silicon (Si) can enhance germination as well as seedling growth. In this experiment, the effect of priming with Si (0, 0.75, 1.5 and 2.25 mM sodium silicate) on seed germination and seedling growth under NaCl (0, 100 a...

Chemical precipitation is a useful technology to remove ammonium (NH(4)(+)) from landfill leachate. In this paper, the removal of ammonium from landfill leachate was studied. The objective of this study was to investigate optimum pH, optimum molar ratio, and different kinds of chemicals combinations for magnesium ammonium phosphate (MAP) precipitation. Furthermore, the kinetics of MAP formation...

This paper is concerned with the effect of individual Na+, K+, Mg2+ and Ca2+ ions upon the nutrient dynamics and cell morphology during submerged fermentation of Aspergillus giganteus MTCC 8408 in a medium containing ample soluble starch, corn steep liquor and proteose peptone supply. Nutrient dynamics was elucidated using Taguchi's DOE (design of experiment) L8 orthogonal array (OA) with carbo...

High-resolution (R ≈ 100 000), high signal-to-noise spectra of M71 giants have been obtained with HIRES at the Keck I Telescope in order to measure their Mg isotopic ratios, as well as elemental abundances of C, N, O, Na, Mg, Al, Si, Ca, Ti, Ni, Zr and La. We demonstrate that M71 has two populations, the first having weak CN, normal O, Na, Mg, and Al, and a low ratio of Mg/Mg (∼4%) consistent w...

We have recently calculated (Borges et al. 1995) integrated metallicity indices for single stellar populations (SSP). Effects of age, metallicity and abundances were taken into account. In particular, the explicit dependence of the indicesMg2 and NaD respectively on the ratios [Mg/Fe] and [Na/Fe] was included in the calibration. We report in this work an application of those models to a sample ...
