Spectrophotometric determination of ruthenium(III) with N-decylpyridine-4-amine in xylene from succinate medium was carried out. Ruthenium(III) was extracted quantitatively with 10 ml of 1 x 10(-4) M reagent concentration in xylene from 0.001 M sodium succinate concentration in 25 ml aqueous phase with 2% sodium chloride solution and estimated spec...

Spectrophotometric determination of palladium(II) with N-decylpyridine-4-amine in xylene from malonate medium was carried out. Palladium(II) was extracted quantitatively with 10 ml of 1 x 10(-4) M reagent concentration in xylene from 0.025 M sodium malonate concentration in 25 ml aqueous phase with 1 : 1 ammonia and estimated spectrophotometrically...

Porcelains are vitrified and a fine grained ceramic product, used either glazed or unglazed and is often manufactured from a tri-axial body mix of clays, quartz and alkaline feldspar. Physical properties associated with porcelain include those of permeability, high strength, hardness, glassiness, durability, whiteness, translucence, resonance, brit...

The present study was undertaken to investigate the effect of various extracts of fruit peel of Annona squamosa on blood glucose and lipid profile in streptozotocin induced diabetic rats. Different extracts (Petroleum ether, Ethyl acetate and Alcoholic) of Annona squamosa fruit peel was administered orally (250mg/kg body weight) for 21 days. The ef...

Thermal conductivity and thermal diffusivity of blended clays have been studied with special reference to Ukrainian clay. The blends were made of three different clays available locally in western part of Rajasthan. Thermal conductivity and thermal diffusivity were determined using the transient plane source (TPS) technique at room temperature and...

ZnO powder was synthesized by solid state reaction method. The synthesized powder was granulated and pressed using uni-axial press for preparing the pallets. The prepared pellets were sintered in conventional furnace at different temperatures (900-1300° C). The phase study was done by powder X-ray diffraction and it was found that the there is no o...

Extraction of rhodium(III) with 4-(4-ethylbenzylideneimino)-5-methyl-4H-1, 2,4-triazole-3-thiol (EBIMTT) from malonate media is described. Extraction was found quantitative with 0.1 M EBIMTT in chloroform in the pH range 1-2. From organic phase of EBIMTT, rhodium(III) was stripped out with 1 M HCl and determined spectrophotometrically with standard...

This paper investigates the particle size distribution, chemical composition, fired modulus of rupture (MOR), and apparent porosity of blended clay utilizing clays available in Bikaner region and comparison with a imported Ukrainian clay. The blended clay B2 presents good white buff fired colour, higher fired modulus of rupture, and low porosity. T...

The effects of furnace sorbent injection on waste characteristics and the performance of electrostatic precipitators (ESPs) have been studied under conditions simulating full scale operation at Ontario Hydro's 640 MJ/h Combustion Research Facility. Twice as much waste was produced as with coal ash; the waste was found to contain high levels of calc...

Thermo-mechanical properties like modulus of elasticity or Young's modulus and fracture energy or toughness of blended clays have been studied with special reference to Ukrainian clay which is imported by local ceramic plant owners. The blends were made of three different clays available locally in western part of Rajasthan (India). It was found th...

The performance of an electrostatic precipitator (ESP) to collect moderately high resistivity flyash has been tested under pulse/precharger energization using the semipilot scale integrated electrostatics combustion flue gas (IECFG) cleaning system at Ontario Hydro's 640 MJ/h Combustion Research Facility Center. The pulse energization enhanced the...

A novel pulse module for enhancing electrostatic precipitator (ESP) performance has been developed and tested using Ontario Hydro's 640 MJ/h Combustion Research Facility. The pulse energization enhanced the performance of the existing DC energized wire-plate ESP by suppressing back corona in collecting high-resistivity flyash (⩾10 ¹⁰...

Clinical and morphological studies clearly indicate that most human coronary artery stenoses are capable of vasomotion. Variable ischemic thresholds, ischemia unrelated to work load, and variant angina further show the presence and importance of vasoconstriction in coronary artery stenosis. Despite the importance of vasoconstriction, the effect of...
