Both transgenic lines showed browning of the lamina joint regions and nodes that could be attributed to a reduction of RGB1 function, as the abnormality

was not observed in d1-5. The RGB1 knock-down lines generated in d1-5 were shorter, suggesting RGB1 to be a positive regulator of cellular proliferation, in addition to RGA1. The number of sterile seeds also increased in both RGB1 knock-down lines. These results suggest that G beta gamma and G alpha cooperatively function in cellular proliferation and seed fertility. We discuss the potential predominant role of RGB1 in G protein signaling in rice.”
“Borehole and sachet (“”pure water”") water are the major sources of drinking water in Calabar. Such waters are required to comply with minimum standards in order to protect public health and accepted as safe drinking water. In this paper, a study was conducted to investigate DAPT cost the presence and effects of fungi in sachet and borehole drinking water in Calabar using 4 sachet water samples and 10 borehole samples. Sachet water aged 2 h and 2 weeks since manufactured and each borehole sample (collected in the dry and wet seasons) was subjected to membrane filtration technique and plating method to determine the fungal content of the water. Only one sample, Usua water (sachet water) tested negative for the presence of fungi at CFU (colony forming unit) / 100 ml. Laura water (sachet

water), Abua water, Edgerly water and Mayne-Avenue Go 6983 research buy water (borehole water) were the most infected. Percentage of fungi in borehole water was higher in the rainy than in the dry season. Aspergillus (29.4%), Rhizopus

(21.6%), Fusarium (15.7%) and Penicillium (13.7%) were the most frequently isolated. These fungi have the potential to cause allergic reactions or diseases in humans.”
“Volumetric oxygen transfer coefficient and oxygen uptake rate in a dense activated sludge slurry bubble column NVP-BSK805 were measured by varying activated sludge concentrations (from 2000 to 8000 mg/L) and/or aeration rates (from 0.3 to 1.5 L min(-1)). They were separately determined by the dynamic methods. The endogenous oxygen uptake rate of the activated sludge was estimated by monitoring the dissolved oxygen concentration change after turning off the air sparging in a stirred tank. The volumetric oxygen transfer coefficient in a dense activated sludge slurry bubble column was determined using the dissolved oxygen concentration profiles and the oxygen uptake rates predetermined from the separate measurements. While the oxygen uptake rate almost linearly increased with increasing the activated sludge concentration, the volumetric oxygen transfer coefficient decreased with an increase in the activated sludge concentration. Their empirical correlations were obtained as functions of activated sludge concentration by fitting the experimental data.
