Adverse events included diarrhoea (three Phytopica (TM) and one placebo treated dog), polyuria/polydipsia (three dogs in each group), and polyphagia, intermittent anorexia and panting (one dog each in the placebo group). None of these by themselves

required withdrawal of treatment.”
“Emission of gamma rays from buried and exposed radioactive materials poses health risks at radiologically contaminated sites. Covering the source material with a barrier of adequate thickness and physicochemical composition can reduce the intensity of transmitted gamma rays (gamma), thereby reducing see more such risks. Herein, the Geo-Radiological Barrier Gamma Attenuation Model (GRBGAM) is developed to quantify gamma attenuation by earthen covers. The model allows variation of barrier and radioactive selleck chemicals source input parameters and comparison of emitted gamma intensities and attenuation ratios of different barrier designs for virtually any radioactive isotope decay chain. The model calculates the activities of successive amounts of decaying

isotopes within a decay chain and temporally couples the results with an exponential absorption equation to estimate the exit intensity of gamma radiation from barriers. A Weibull function integrated into the absorption selleck inhibitor equation, scales temporal changes in barrier density (rho(‘)) during long service times. This model can be used to optimize georadiological (georad) barrier mix composition and thickness

to increase gamma attenuation ratio to acceptable levels.”
“A porous LiMn2O4 consisting of nano grains was prepared by using polystyrene as template. It was studied as a cathode material for aqueous rechargeable lithium batteries (ARLBs) using 0.5 mol l(-1) Li2SO4 aqueous solution as the electrolyte. Charge and discharge capacities at a current density of 10 A g(-1) (about 90C) were 76% and 95% of the total capacity (118 mAh g(-1)), respectively. The power density can be up to 10000 W kg(-1) and the cycling behavior is excellent. After 10000 cycles at 9C with 100% DOD (depth of discharge), the capacity retention of porous LiMn2O4 is 93%, which indicates that it can be used for a lifetime without maintenance. The main reasons for its excellent electrochemical performance are due to the nano grains, porous morphology and high crystalline structure. In addition, the acid-free aqueous electrolyte prevents Mn2+ from dissolution. These excellent results suggest a great promise for the development of aqueous rechargeable lithium batteries (ARLBs) in practical application.
