The F(1) and F(2) progenies of a ten-parent diallel cross (excluding reciprocals) of hexaploid wheat (Triticum aestivum L. em. Thell) were analyzed for combining ability for quantitative and quality traits. The results indicated significant differences among the parents for general combining ability (gca) and crosses for specific combining ability (sca) for(More)
Lethal mutations in the giant discs (lgd) and fat (ft) tumor suppressor genes of Drosophila cause epithelial hyperplasia in all imaginal discs. By contrast, mutations in the vestigial (vg) gene adversely affect cell viability in the wing imaginal discs and consequently cause loss of pattern in the adult wings. However, combining homozygous lgd or ft(More)
A simple colorimetric method is described for the determination of pyridoxine hydrochloride (vitamin B6). The method is based on the measurement of an orange species formed when pyridoxine hydrochloride is treated with diazotized dapsone and sulfanilamide in a mixture of trichloroacetic acid and sulfuric acid at room temperature, followed by treatment with(More)
A simple gas chromatographic method is described for the determination of histapyrrodine HCl in marketed formulations. Chlorpheniramine maleate is used as the internal standard. The amount of histapyrrodine HCl found by the proposed method averaged 19.91 mg/tablet, compared with the label claim of 20 mg/tablet. The method was statistically evaluated for(More)
The problem of spectrum sharing between two operators in a dynamic network is considered. We allow both operators to share (a fraction of) their licensed spectrum band with each other by forming a common spectrum band. The objective is to maximize the gain in profits of both operators by sharing their licensed spectrum bands rather than using them(More)
Complete 1H and 13C spectral assignments are reported for six saponins from the pericarp of Sapindus trifoliatus (Hindi name: Reetha) collected from Madhya Pradesh and Maharashtra, India, using only 1D and 2D NMR methods. The structures of the compounds were elucidated as hederagenin(More)
A simple colorimetric method is described for the determination of thiamine hydrochloride (vitamin B1) in dosage forms. The method is based on measurement of a yellow complex formed when thiamine HCl is treated with p-methylaminophenol sulfate (Metol) under alkaline conditions. Compounds such as vitamins A, B2, B6, B12, C, D, and E, and niacinamide, citric(More)
X-ray K-absorption near edge studies have been carried out on the binuclear copper (II) dithiocarbamate (dtc) complexes having the following general structure: [structure in text] where R = me (methyl); et (ethyl); npr (normal propyl); chx (cyclohexane) It has been found that the chemical shift values are higher in the chlorine adducts as compared to the(More)
