The hematic parameters of cows selected for milk production in grazing under tropic conditions were analyzed based on six experimental studies. major objective was to determine statistical analysis alternatives that could be used the study physiological, environmental or genetic variations. hematocrit, hemoglobin concentrations and counts polymorphonuclear cells (i.e., eosinophils, basophils, n...

ABSTRACT The Government of Canada's Oceans Protection Plan (OPP) is a comprehensive, transformative $1.5 billion strategy to build world-leading marine safety system protect ecosystems, while enabling inclusive economic growth. A key component the OPP Multi-Partner Research Initiative (MPRI), led by Fisheries and Canada (DFO) in collaboration with other federal agencies (Environment Climate Cha...

The aqueous biphasic system (ABS) method using PEG and ammonium sulphate improved the recovery of spores from tropical soils as compared with the sucrose gradient method. The ABS was not affected by low temperatures. The optimal recovery of spores was achieved when 100% PEG and 50% ammonium sulphate concentration and PEG8000 instead of PEG4000 were used. Under these conditions an optimal interf...

The reliability of electronic device is threatened in high power microwave (HPM) environment. In accordance with the situation that the emulation is ineffective in evaluating the accuracy and precision of the HPM effect to electronic device, the experimental method is used to resolve the problem. Low Noise Amplifier (LNA) and Limiter are selected as the objects for the experiments, the structur...

Pear juice obtained from pear concentrate was fermented at room temperature using Saccharomyces cerevisiae (BDX, ENOFERM, France) as the fermentation microorganism. During the fermentation process, total sugars were measured. High performance liquid chromatography analyses were used to monitor the fermentation process and to characterize the pear wine. The pear wine obtained was distilled with ...

THE milk-fats from goats and sheep are used, although only to a small extent, as substitutes for those of cows and buffaloes in India. The component fatty acids and glycerides of these two fats have been studied by methods recently developed [Hilditch et al., 1929; 1930; 1931] in the case of cow butter-fats, in order to compare their composition with those of the latter and, in certain respects...

The preparation of the silica gel is similar to the method of Bulen, et al (2) for organic acid chromatography. Silicic acid (Mallinckrodt's 100 mesh analytical reagent) is prepared, generally in one pound batches. by repeatedly washing it in distille(d water, and decanting the fine particles that do not settle out of suspension after an arbitrarily chosen period of 15 minutes. After the silici...

HE AUTHORS’ LABORATORY has employed the modified Zlatkis method (1) of Zak and associates (2) for the routine determination of serum cholesterol fractions for over a year with generally satisfactory results. However, ester fractions greater than 80 per cent of the total cholesterol values were occasionally obtained. Recently, an analysis of the serum “total cholesterol” from a patient with acut...

It is well known that the principal disadvantage of any method for the determination of calcium involving precipitation as calcium oxalate lies in washing the precipitate. The solubility of the precipitate in water or in dilute ammonium hydroxide is appreciable and, in centrifuging, a small amount of calcium oxalate tends to float on the surface of the liquid and is lost in decanting. The satis...
