    Notes: Abstract A mixed culture of cyanobacteria (BGA) containingAulosira sp.,Aphanothece sp., andGloeotrichia sp. were grown throughout the year to assess the influence of seasonal variables on their biomass production and nitrogen (N)-yield under field conditions. The seasonal variables considered in this study, i.e., water temperature (maximum, minimum), solar radiation, sunshine hours, and rainfall, fluctuated widely. Attempts were made to establish a relationship between seasonal changes as independent variables and BGA productivity and N-yield as dependent variables. The analysis indicated that solar radiation was the prime factor. Estimates of BGA biomass production varied from 3.3 to 366.5 kg (dry wt)/ha/month, and N-yield ranged from 0.1 to 11.8 kg N/ha/month. The nitrogen accumulated during the study period was 71.2 kg N/ha. The variations explained by seasonal changes were 52.3 and 50.3% for biomass production and N-yield of BGA, respectively.

    Notes: Summary Field experiments were conducted to assess the effects of the application of P on growth and N yield of inoculated and indigenous blue-green algae (BGA). Addition of 17.4 kg P ha−1 in split applications led to the highest BGA biomass and N yield, 162 kg dry weight ha−1 and 6 kg N ha−1 per 15 days, respectively. When inoculum of Aulosira spp., Aphanothece spp., Gloeotrichia spp. were compared separately, Gloeotrichia spp. grew faster but Aulosira spp. fixed more N. The growth rate and N yield of Aulosira spp. decreased with high P applications, although growth continued until the application of 34.8 kg P ha−1. The effects of P on inoculum production by local species compared with those collected from other states showed the superiority of the local culture. Applications of P also enhanced the growth and N yield of indigenous BGA, with Wollea spp. showing the best results.

    Notes: The analysis of experimental data of magnetomicrowave Kerr effect in MgMn ferrite samples at 9.442 GHz has been carried out using external permeability tensor components which take care of demagnetizing fields more accurately in the theory and is based on the guided wave propagation of the microwave inside the sample. The present analysis gives a better agreement with the experimental data in comparison to our earlier analysis which was based on the free-wave propagation of the microwave. The importance of the image effect in the demagnetizing factor is also discussed.

    Notes: The electric, dielectric permittivity, loss tangent, microwave power absorption, and hysteresis loop parameters were studied on a series of cobalt-substituted lithium titanium ferrites. The experimental results indicate that cobalt substitution affect all these parameters. The observed dispersion in conductivity and dielectric permittivity with frequency and temperature are in accordance with Maxwell–Wagner model while the microwave and hysteresis loop properties can be interpreted with the help of Dionne's exchange isolation model.

    Notes: Summary Urine chemistry of 42 normal subjects (NS) and 59 ureteric stone formers (SF) from Jodhpur region of Rajasthan, India is presented. Twenty four hour urinary levels of calcium, oxalic acid and uromucoids were significantly higher and levels of magnesium, citric acid and inorganic phosphorus were significantly lower in SF as compared to NS. No significant difference was observed in the uric acid, sodium and potassium levels in the two groups. Significant correlation was observed between calcium and magnesium; calcium and oxalic acid; calcium and citric acid; magnesium and oxalic acid; and oxalic acid and citric acid in NS on the basis of mmol/l but not on the basis of mmol/24 h. Calcium and oxalic acid correlation was uninfluenced by magnesium and citric acid levels. The log of risk factor index (RI) was higher (p〈 0.001) in SF (−1.652) as compared to NS (−2.103). The log of ion activity product (IAP) was also higher (p〈 0.001) in SF (−3.192x10−3) than in NS (−2.914x10−1). Based on RI and IAP, a scale has been devised for the prediction of the risk of stone formation and recurrence.

    Notes: Summary Selection in the F3 generation for seed yield, fruiting branches/plant, effective pods/plant, and seed index (100-seed weight) was carried out in two chickpea crosses. Sixty F5 lines (15 lines/selection criterion) along with check variety were evaluated for seed yield in three distinct environments. The effects of selection criteria on yield stability was examined using linear regression approach and genotype-grouping technique. There were no differences between selection criteria for linear yield responses of F5 lines to different environments. Within all four selection criteria the lines showed similar linear responses. The non-linear component was relatively higher for lines selected for effective pods and seed index than lines selected for yield and fruiting branches. On the basis of mean yield and coefficient of variation across environments, the seed index was the least effective selection criterion for developing high yielding and stable lines. When the results of stability parameters and genotype-grouping technique were considered together, selection for yield and fruiting branches was highly effective for isolating stable and high yielding lines.
