in this study, we aimed to investigate reproductive performance in estrus-induced zandi ewes treated with equine chorionic gonadotrophin (ecg) injection in combination with prostaglandin f2α (pgf2α)and gonadotrophin releasing hormone (gnrh) during non-breeding season. the estrous cycle was synchronized using controlled internal drug release (cidr) for 12 days. the ewes were randomly assigned to...

The reduction of SO2 and PM for marine engines was investigated using the electrostatic precipitator (ESP) with the heat exchanger. The experiments were carried out to reduce SO2 due to condensation of water in the exhausted gas. The experimental system consists of the diesel engine, the heat exchanger and the ESP. The exhausted gas at 180 o C of the temperature is cooled to 20 o C, and generat...

It has been found that tissues fixed for electron microscopy and dehydrated in acetone can be embedded in mixtures of n-butyl methacrylate and polyester resin. Activation with 1 per cent tert-butyl hydroperoxide followed by 12 to 48 hours at 60 degrees C produces blocks that section well with glass knives. The ribbons are cleared of methacrylate by heat (200-250 degrees C for 1 hour) and/or imm...

The effect of heat-dispersing on sticky substances in a deinking pulping line was studied under different conditions including varying temperature, disc clearance, and pulp consistency. Sticky substances were quantitatively investigated before and after the heat-dispersing, and categorized into macro-, mini-, and micro-stickies as well as dissolved and colloidal substances. Meanwhile, their ext...

The evaporation of sprinkler droplets is an important phenomena in fire simulations both for heat removal from the gas and for heat removal from surfaces. The Fire Dynamics Simulator (FDS) has seen a number of different evaporation models over its history where each subsequent model has attempted to address limitations and issues with the previous model. In this paper, we address the problems o...

M oday, O cber 9, 2017 is hindered in part by the availability of limbs which can survive a limited amount of time disconnected from the body. Cryobiology is the scientific field which investigates biology at low temperatures. Cryobiologists have long sought to cryopreserve biological samples ranging from single cells to complex organs and whole animals. Vitrification is the transformation of a...

There are two biological systems available for removing phosphorus from waste water, conventional phosphorus removal (CPR) and denitrifying phosphorus removal (DPR) systems, and each is characterized by the type of sludge used in the process. In this study, we compared the characteristics associated with the efficiency of carbon utilization between CPR and DPR sludge using acetate as a carbon s...

As the number of transistors increases with new generation of microprocessor chips, the power draw and heat load to dissipate during operation increases. As a result of increasing the heat loads and heat fluxes the Conventional cooling technologies such as fan, heat sinks are unable to absorb and heat transfer excess heat dissipated by these new microprocessor. So, new technologies are needed t...

Industrial application of hot processing beef and pork are presented. Even though the research community has presented many glowing advantages for processing the meat animal immediately after dressing, the commercial processing industry has been slow in adopting this innovative system of processing. The whole concept of hot processing requires such a vast change in the present segmented operati...

Clinical results of port wine stain (PWS) birthmarks laser therapy have shown that dark purple lesions usually respond well to the first 3–5 treatments. However, for most PWS, complete blanching is never achieved, and the lesion stabilizes at a red-pink color. We have recently demonstrated that with the aid of a local vacuum applied to the lesion site prior to laser irradiation, photocoagulatio...
