Background The objective of the study was to investigate the effects of in vitro zinc sulphate additive to semen extender on sperm parameters (progressive motility, viability, membrane integrity and DNA stability) after cryopreservation. Materials and Methods In this Prospective longitudinal laboratory study, semen samples of 5 buffalo bulls of 3-5 years old were collected at 5 different occasions from Iran, Urmia during summer and autumn 2011, 25 samples were used in each treatment. Sperm progressive motility, viability and abnormal morphology were measured before and at 0.5 (T0), 1(T1) and 2(T2) hours after diluting semen(1:10 v/v) in Tris-citric acid based extender (without egg yolk and glycerol) at 37C containing none (control group), 0.072, 0.144, 0.288, 0.576 and 1.152 mg/L zinc sulphate to investigate dose and time effects. Next, a Tris-citric acid-egg yolk-glycerol extender (20% egg yolk and 7% glycerol) containing the same amount of zinc sulphate was prepared, diluted semen (1:10 v/v) was cooled and kept into a refrigerated chamber (4C) for 4 hours to equilibrate. Sperm progressive motility, viability, abnormal morphology, membrane integrity and DNA damage were estimated.The equilibrated semen was loaded in 0.5 ml French straws and frozen in liquid nitrogen. Later, the frozen semen was thawed and the same parameters as well as total antioxidant capacity (TAC) of the frozen-thawed semen were determined. Results The results showed that zinc sulphate additive at the rate of 0.288 mg/L gave a higher protection of sperm progressive motility (53.7 1.8% vs. 40.5 1.7%), viability (70.8 1.8% vs. 60.1 1.5%), membrane integrity (67.3 1.6% vs. 56.6 1.7%), DNA stability (10.1 0.47% vs. 11.8 0.33% damaged DNA) through the process of dilution, equilibration and freeze-thawing and caused a higher TAC level (81 3.3% vs. 63 3.2 mol/L) after freez-thawing compared to the control group. Adding 0.576 and 1.152 mg/L zinc sulphate, however

In the Loesche mill, Fig. 2.23,16 two pairs of rollers are used. In each pair the first, smaller diameter, roller stabilises the bed prior to grinding which takes place under the larger roller. Manufacturers use different technologies for bed stabilisation

While this article wont address instruments related to productivity and quality, there are an increasingly wide array of solutions being offered. Sensors can evaluate grain temperature and moisture, monitor the relative humidity of dryer supply and exhaust air streams, track the electrical current draw on motors, and collect a mass of other data to be considered by a process operator or fed directly into an automated control system. However, since the grain handling and processing industry is often a low margin business, before installing such technology one should evaluate whether the efficiency and quality gains realized will provide a positive financial return usually it does, but not always

Measuring and managing raw material quality in a cement or coal process can be challenging. Raw materials in the cement manufacturing process must be carefully monitored and controlled to ensure the quality and conformity of the final product, concrete. Variances can result in faulty concrete and potentially dangerous and expensive construction issues such as building and bridge failures. Likewise, coal mining yields products of variable composition and quality that must be accurately sorted, separated, and blended. In both industries, online analysis systems based on Prompt Gamma Neutron Activation Analysis (PGNAA) and Pulsed Fast Thermal Neutron Activation (PFTNA) technology help coal and cement producers proactively address process variations and ensure more consistent raw material composition and quality

There are many types of gate you can add to the end of the driveway to shut yourself away from the world. These are especially useful if you have small children or pets that you need to keep under control. You can even install an electric gate that opens and closes using a remote control or a security sensor. A typical standard driveway gate will cost anything from 500 to 1,000
