    Notes: Abstract Solid thallous carbonate reacts with chlorine gas with the formation of brown-coloured Tl2OCl2 as an intermediate compound. Further exposure to chlorine gas gives the yellow compound Tl4Cl6. Both the compounds contain Tl(I) and Tl(III) ions. The kinetic data obeyw 2=kt. The energy of activation was found to be 41.98 kcal mol−1. Thermo-gravimetry (TG) indicates that Tl2OCl2 decomposes into TlCl, Tl2O3 and chlorine gas above 250° C. In contrast, Tl4Cl6 is stable up to 420° C.

    An experimental evaluation of dependence liability of methaqualone diphenhydramine (combination) and methaqualone in rats (1980)

    Topics: Medicine
    Notes: Abstract In the present study the drugs (Methaqualone + diphenhydramine or Methaqualone alone) were administered daily in a liquid diet to different groups of rats for 3 weeks. Each week the doses of the drugs were increased and daily records of body weight, mean rectal temperature and spontaneous motor activity (SPM) were maintained. During the first week, tolerance to both the drugs was observed when the animals received 152.4 mg/kg-1/day of methaqualone (MQ) and 140.0+14.0 mg/kg-1/day of methaqualone + diphenhydramine (MQ+D) respectively. In the second week the doses were further increased to 302.0 mg/kg-1/day of MQ and 277.8+27.7 mg/kg-1/day of MQ+D respectively. At the end of the second week complete tolerance developed to increased doses of MQ but not to the MQ+D combination. In the third week the doses were further increased to 406.6 mg/kg-1/day of methaqualone and 383.4+38.3 mg/kg-1/day of MQ+D respectively. At the end of this week although there was partial recovery but, compared to the controls, a significant lowering (P〈0.05) of mean rectal temperature and spontaneous motor activity persisted in both groups thus showing an incomplete tolerance to larger doses of both MQ and the MQ+D combination. When the drugs were withdrawn after the third week, both MQ as well as MQ+D treated groups of rats exhibited an increased susceptibility to audiogenic stimuli of, but MQ+D treated animals showed an even greater susceptibility to such stimuli and also a fall in body weight. Further, 50% of rats in MQ+D group died during convulsions while there were no deaths in the group treated with MQ alone. The results of this study suggest that the MQ+D combination causes a more severe degree of physical dependence than MQ alone.

    Effect of sodium and bicarbonate irrigation waters on sodium accumulation and on maize and wheat yields in Northern India (1983)
    Springer
    Irrigation science 4 (1983), S. 191-199 
    Details
    ISSN: 1432-1319
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The effect of five years use of irrigation water containing sodium and bicarbonate on sodium accumulation in soils and yields of maize and wheat was studied in 50 cm diam and 90 cm long pots embeded in trenches in the field. Waters were synthesized by mixing NaCl and Na HCO3 with canal water before each irrigation. Gypsum, required to reduce residual sodium carbonate of the high bicarbonate water to zero, was applied either with each irrigation or once on a cumulative basis to the soil before sowing the next crop. Retention of the applied Na in 75 cm profile was 22 and 44% in Tulewal sandy loam and Nagar loam soils, respectively. The increase in ESP was more highly correlated with SARadj. (r=0.94) than with the residual sodium carbonate content of the irrigation water (r=0.49). ESP increased linearly with SARadj. of irrigation water (r 2 = 0.92) in Nagar loam but showed a quadratic relation (r 2 = 0.84) in Tulewal sandy loam. The maximum average ESP of 75 cm profile after five years was 27.6 and 30.7 in Tulewal and Nagar soils, respectively. Predicted SARdw values were quite close to the ESP of both the soils irrigated with low SARadj. waters but were higher with the waters having SARadj. 〉 25.6. Possible reasons for this difference are discussed. Average yields of maize fodder significantly decreased with increasing levels of EC and SARadj. in waters. A significant negative relationship (Y=109.36–1.948 X was observed between percent relative yield of maize fodder (Y) and average ESP (X) of 75-cm profile. Maize yields were reduced to 50% at an average ESP of 30.5 while wheat yields were unaffected. Gypsum application decreased the rise in pH and exchangeable sodium. Gypsum applied with each irrigation was more effective and produced more maize fodder than when applied on a cumulative basis.

    Notes: Abstract A radiochemical procedure has been developed for the simultaneous determinations of alpha-emitting isotopes of uranium and plutonium in bovine bone. The radiochemical recoveries ranged from 61 to 93% with a mean of 80±10% for uranium and 57 to 88% with a mean of 75±11% for plutonium. The method was successfully used for human bone.

    Regression analysis for general adaptation in pearl millet using different environmental indices (1984)

    Notes: Summary Regression analyses on grain yield of 20 hybrid and 13 composite varieties of pearl millet (Pennisetum typhoides (Burm. S. & H.)) evaluated at 19 sites in India were performed to assess their relative stability and to compare different measures of environmental values. A large portion of the significant genotype X environment interactions was attributed to the non-linear component and deviations mean squares (Sdi 2) were a very important parameter for selection of stable varieties. The mean grain yield was positively associated with regression coefficients and deviations mean squares. The hybrids MH 31, MH 35, MH 36 and MH 62 and composite populations MP 16, MP 31 and MP 36 possessed general adaptability. The use of dependent, independent and near-independent measures of environmental values has been found to have little influence on the general interpretation of regression analysis in pearl millet.

    Effect of CaCl2 on the hydration of tricalcium silicate (1981)

    Notes: Abstract The hydration of tricalcium silicate has been studied at 30° C in the presence and absence of 2 wt % CaCl2 with a water∶solid ratio of 0.8. Free lime determinations, X-ray diffraction analysis, thermal analysis, infra-red spectroscopy, scanning electron microscopy and zeta potential measurements were used for hydration studies. The results indicate that the accelerating action of CaCl2 is due to higher diffusivity of chloride ions.
