This study was conducted to assess the post thaw quality of Kundhi buffalo semen diluted in tris based diluents. After collection the ejaculates were pooled and checked for color, volume, pH, mass activity, progressive linear motility% (PLM), and intactness of cell membrane. The semen qualifying these tests was divided into four aliquots A, B, C and D, diluted with tris based diluents; the last...

Research up to 1993 is reviewed. Various methods for processing, freezing and thawing of semen have been elaborated and their effect on survival and fertility of spermatozoa have been examined in vitro or in fertility tests. Diluents initially used for freezing bull semen had their limitations and were modified or replaced by new media. The freezing diluents investigated included citrate-sugar-...

Vat photopolymerization 3D printing provides new opportunities for the fabrication of tissue scaffolds and medical devices. However, manufacturing biodegradable elastomers, it usually requires use organic solvents to dissolve solid photoinitators achieve low resin viscosity, making this process environmentally unfriendly not optimal biomedical applications. Here, we report solvent-free elastome...

By using lactose colored with erythrocin, we investigated the effects of mixing methods on mixing degree during the preparation of trituration with a mortar and pestle. The extent of powder dilution was set to 4 to 64 fold in the experiments. We compared the results obtained by using two methods: (1) one-step mixing of powders after addition of diluents and (2) gradual mixing of powders after a...

Materials are evaluated for use as in-core diluents and as peripheral reflectors for Gas-Cooled Fast Reactor (GFR) service, using coupled Monte Carlo (MCNP) and isotopics (ORIGEN) codes. The principal performance indices compared were effects on beginning of irradiation multiplication factor, reactivity-lineated burnup, and coolant (here CO2) void reactivity. While low values of the macroscopic...

The solubility ternary system was used to develop a hollow fiber-supported liquid membrane process for the extraction of gold (I) cyanide from electronics industry wastewater. Five kinds diluents (p-xylene, cyclohexene, 1-dodecanol, n-heptane, and n-dodecane) were applied systems (Aliquat336 + water diluents) at 303.2 K atmospheric pressure. p-xylene, cyclohexane selected because they are compl...

To elucidate inconsistencies in rubella haemagglutinin assays the components of the assay technique were examined. The results of carefully controlled assays of rubella haemagglutinin antigens from different sources in various plates and diluents with four species of indicator cells are reported. The quality and quantity of gelatin in the dextrose-gelatin-veronal buffered diluent commonly used ...

The production of nicotinic acid and nicotinamide can be intensified by enzymatic conversion of 3-cyanopyridine. This fermentation process requires an economic and efficient separation method to compete with the synthetic process. In the present study, equilibrium data for the extraction of nicotinic acid using TOA dissolved in different diluents such as toluene and butyl acetate and n-dodecane...
