this study aimed at determining the physico-morphological attributes, in vitrofertilityand their interrelationships in semen of sahiwal bulls. semen samples werecollected weekly for 6 weeks from ten mature sahiwal bulls divided randomly into 5 groups. the mean (±sem) of ejaculate volume (ml), mass activity (score 0-5), progressive sperm motility (%), sperm concentration (106/ml), live sperm (%)...

Infectious pancreatic necrosis (IPN) virus has been purified and some physicochemical properties of its nucleic acid and protein moieties have been determined. The buoyant density of the virus particle in CsC1 is 1.35 g/ml; degraded particle banded at a density of 1.31 g/ml. The virus nucleic acid was found to be doublestranded, according to several different criteria, namely resistance to panc...

This research was conducted to study and classify the physico-chemicalproperties of soil, yield components of wheat and to determine the significance ofthese parameters on the grain yield formation. In this research, seven statisticalmethods consisting of simple correlation analysis (SCA), multiple linear regression(MLR), stepwise regression (SR), factor analysis (FA), principal componentanalys...

Environmental factors can directly influence phenotype such that a tight correlation between morphological and environmental variation is expected. However, morphological response to environmental variation may also reflect constraints imposed by interactions between adjacent structures such as the gills and the trophic apparatus in fishes. Such complex interactions help to explain why an organ...

Citrus fruit tree has great commercial importance with mandarin (Citrus reticulata) as the second most important citrus crop and includes a wide range of true hybrid cultivars; however, there is lack studies about characterization evaluation germplasm for Physico-chemical morphological traits. A study on varietal selection been underway at National Research Programme since 2005-06. Evaluation s...

A novel compound MS-444 was isolated from the culture broth of a bacterial strain KY7123. The strain was identified as Micromonospora sp. from its morphological and cultural characteristics. The compound inhibited the activity of purified smooth muscle myosin light chain kinase with an IC50 value of 10 microM. The production, isolation, physico-chemical properties and biological activities of M...

Monitoring pluripotent stem cell behaviors (self-renewal and differentiation to specific lineages/phenotypes) is critical for a fundamental understanding of stem cell biology and their translational applications. In this study, a multi-modal stem cell monitoring system was developed to quantitatively characterize physico-electrochemical changes of the cells in real time, in relation to cellular...

To elucidate the correlation between enhanced biogas production and changed physico-chemical properties of methanogenic granules after low strength ultrasonication, in this study, the effects of low strength ultrasonication on the settling velocity, permeability, porosity, and fluid collection efficiency of the methanogenic granules were investigated. In addition, their morphological changes we...
