A lab experiment was carried out to assess the effect of sodium chloride (75 and 150 mM NaCl) and uniconazole (10 mg/l) on the soluble protein, proline and total soluble sugars content and activities of nitrate reductase (NR), in cotyledonary leaves of Ziziphus mauritiana var. rotundifolia. NaCl stress decreased the soluble protein content and NR activity whereas, proline and total soluble sugars content increased significantly at 4,7 and 9 days after seed sowings (DAS). Treatment of uniconazole with combination of NaCl (75 and 150 mM) alleviates the adverse effect of the NaCl, exhibited increases in NR activity and soluble protein content compared with NaCl treatment. The proline and total soluble sugars contents was more at 9 days after sowing (DAS) with uniconazole alone and in combination of 150 mM NaCl respectively. The NaCl salinity was partially ameliorated by uniconazole might be due to increase in metabolites level (i.e. soluble protein, proline, total soluble sugars) and NR activity.

Indole-3-Butyric acid (I-3-BA) is a plant hormone in the auxin family and is an ingredient in many commercial horticulture plant rooting product. It is a growth regulating hormone and is biologically and analytically an important molecule. Micellar solubilization of I-3-BA in nonionic and ionic surfactants heteromicroenvironment is monitored by fluorescence and absorption spectral techniques has been reported by the authors. The influence of surfactant, concentration and working experimental conditions on the fluorescence spectra of I-3-BA is thoroughly evaluated and discussed. The increase in fluorescence intensity in micellar media can be attributed to the increase in quantum efficiency suggests that the suspended hydrophobic I-3-BA molecules have been solubilized. The solubilizing action has been supplemented and confirmed by few theoretically calculated spectral parameters like, empirical fluorescence coefficient (kf), quantum yield (φf), molar extinction coefficient (e) and Stokes' shift values.

In present study, physico-chemical characteristics and fatty acids composition of kakri (Cucumis momordica L.) seeds oil were determined. oil contents, protein contents, moisture content, free fatty acid, saponification values, iodine values, refractive index, specific gravity, unsaponifiable matter and fatty acids composition of oils extracted from seeds were determined. The oil content was 22.22%. The oil consists of 68.16% of unsaturated fatty acids and the main fatty acids are linoleic acid (52.63%), palmitic acid (21.05%), oleic acid (14.33%), stearic acid (10.79%) and linolenic acid (1.20%). The other characteristics of the kakri seeds oil are approximately as follows: protein contents, 16.40%; moisture content, 7.0%; free fatty acid, 3.6%; saponification value, 126; refractive index, 1.479; specific gravity, 0.914 g/cm3; unsaponifiable matter, 2.5% and iodine value, 176.

Quinine hydrochloride (QH) is a pharmaceutically important heterocyclic alkaloid derived from the bark of cinchona tree. Micellar solubilization of QH in nonionic and ionic surfactant heteromicroenvironment monitored by fluorescence and absorption spectral techniques has been reported by the authors in this communication. The relatively week fluorescence of QH was significantly enhanced in nonionic micellar media formed by Tween-20 surfactant. The influence of the surfactant, concentration and working experimental conditions on the fluorescence spectra of QH is thoroughly evaluated and discussed. The solubilizing action of the surfactants has been confirmed by the theoretically calculated spectral parameters like, empirical fluorescence coefficient, quantum yield, molar extinction coefficient and Stokes' shift. The authors provide a unique format for the analytical and medicinal application of QH based on micellization of the surfactants which makes them promising drug carriers, employing fluorescence, absorption and light scattering measurements.

This paper is based on a study and generic investigation on the slope stability of highwall in Saniem iron ore mine, Goa. For geotechnical details, the results of investigations carried out by various agencies for the mine in the past were reviewed. They were also compared to literature and results for the similar rocks in the Goa region. Based on all these a set of strength parameters was developed. These were validated by having sensitivity analysis of recently failed and existing slopes. Sensitivity analyses were carried out for ultimate pit slopes both in foot wall and hanging wall. For design of slopes at Saniem mine, five models for foot wall and six models for hanging wall were prepared along the two sections. In all the models the height and slope of the benches were 6.0 M and 70 degree, respectively. The width of benches varied from 8 M to 12 M.Based on the analysis of the results the most appropriate ultimate pit slope is the one with bench width of 10 M provided the groundwater is not allowed to form any unconfined aquifer. With 10 M and 12 M wide benches, the ultimate pit slopes are 26 degree and 23 degree, respectively excluding the wider benches.
