milk urea nitrogen (mun) of dairy cows was determined in relation to breed. a total of forty (40) pabna and red chittagong dairy cattle each of twenty (20) were selected to know the milk composition, nutritional status and milk urea nitrogen. live weight of pabna cattle (187±14 kg) was higher than that of red chittagong cattle (174±4 kg). in pabna cattle milk yield (4.94 kg), minerals (0.15%) a...

The effect of orally administered sun ginseng (SG), which is a ginseng processed by steaming, was examined in adenine-induced chronic renal failure rat. SG significantly decreased both blood urea nitrogen and serum creatinine levels, indicating an improvement of renal function. Also, SG significantly increased the urinary excretion of both urea and creatinine. Furthermore it lowered the blood p...

protein nutritional status of dairy cows. Milk urea nitrogen reflects the amount of urea found in milk and these values are closely correlated with the concentration of urea found in the blood. MUN values should not be used by themselves when evaluation a herd’s feeding program but can be used in conjunction with evaluating milk production records, feeding management practices, and dry matter, ...

Automated blood glucose and urea nitrogen procedures have been modified for use with the Technicon 15-mm. tubular flow-cell colorimeter to take advantage of the resulting increased sensitivity and economy. Flow diagrams for these procedures as well as for the simultaneous determination of glucose and urea are presented. Recovery and reproducibility data are given to indicate the reliability of ...

A radical generated on the side-chain of a 2- or 4-N-alkylamino-4,6- or 2,6-dichloropyrimidine can cyclise on the nitrogen or on the carbon of the pyrimidine ring depending on its position and on whether an acetyl or a Boc group is present on the extra-nuclear nitrogen.

Efficient readout of individual electronic spins associated with atomlike impurities in the solid state is essential for applications in quantum information processing and quantum metrology. We demonstrate a new method for efficient spin readout of nitrogen-vacancy (NV) centers in diamond. The method is based on conversion of the electronic spin state of the NV to a charge-state distribution, f...

Saprotrophic fungi are the primary decomposers of plant litter in temperate forests, and their activity is critical for carbon (C) and nitrogen (N) cycling. Simulated atmospheric N deposition is associated with reduced fungal biomass, shifts in fungal community structure, slowed litter decay, and soil C accumulation. Although rarely studied, N deposition may also result in novel selective press...

The development of the leather industry in the Aojiang watershed of Zhejiang province increased the release of waste water. In the waste water, ammonium nitrogen (NH(+) (4)-N) and germanium (Ge) are the main pollutants. In recent years, literature has documented that the intake of high concentrations of NH(+) (4)-N and Ge harms human health and biological species. This paper focuses on assessin...
