In the context of modern power systems the multi objective feeder reconfiguration problem has assumed significant importance. This paper presents a fuzzy set theory based approach for the multi objective network reconfiguration of distribution system. The multiple objectives which are met are feeder balancing, minimize power losses, feeder-current constraints and deviation of node voltage. The ...

A meta-analysis, using information from 45 experiments on growing-finishing pigs published in 39 manuscripts, was carried out to determine the simultaneous effects of the physical environment (space allowance, group size, flooring conditions, temperature, presence of enrichment), pig traits (initial body weight (BW) for each studied time interval, sex, genetics), feeder characteristics (water p...

a general synthetic route to the synthesis of imidazoles has been developed using nano sbcl5/sio2 under solvent-free conditions. the multi-component reactions of aldehydes, benzil and ammonium acetate were carried out to afford some trisubstituted imidazole derivatives. this method provides several advantages like simple work-up, environmentally benign, and shorter reaction times along with hig...

Many horse owners find round bales convenient, less labor intensive, and more affordable than other hay types, but report an inability to control horse BW gain and excessive hay waste. The objectives were to compare hay waste, hay intake, and payback of 9 round-bale feeders and a no-feeder control when used during horse feeding. Nine round-bale feeders were tested: Cinch Net, Cone, Covered Crad...

This research evaluates the efficiency of swine firms differing by specialization type and employed technologies. Measures of technical, allocative, scale, economic, and overall efficiency are separately and jointly estimated for farrow-to-finish, farrow-to-feeder, feeder-tofinish, farrow-to-weanling, weanling-to-feeder, and mixed operations. Findings confirm appreciable differences in efficien...

Human ES cells (hESCs) and human induced pluripotent stem cells (hiPSCs) are usually generated and maintained on living feeder cells like mouse embryonic fibroblasts or on a cell-free substrate like Matrigel. For clinical applications, a quality-controlled, xenobiotic-free culture system is required to minimize risks from contaminating animal-derived pathogens and immunogens. We previously repo...

Feeder cattle are fattened to become fed live cattle six months later. The U.S. feeder cattle industry is intensively competitive, so that market efficiency suggests feeder cattle prices should fully reflect feed prices and information on future fed cattle prices. Employing a long time series (1979-2004) of feeder cattle futures, live cattle futures, and local corn prices, we test whether compl...

This study aims to determine the condition factors influencing the in vitro proliferation culture of spermatogonial stem cells (SSCs) through isolation and culture of SSCs. With mouse embryonic fibroblast (MEF) cells, SIM-6-thiogunanie-oualiain (STO) cells and Hela cells used as the feeder layers, we compared the numbers of cell clones treated with mitomycin C as well as the proliferation condi...

umbilical cord blood (ucb) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (hscs). because of insufficient number of cord blood cd34+ cells, the expansion of these cells seems to be important for clinical application. mesenchymal stromal cells (mscs), playing an important role in hscs maintenance, were used as feeder layer. apo...

The primary heat transport system of a typical CANDU®-6 nuclear power reactor contains 760 feeder pipes. These feeders carry the coolant between the inlet or outlet headers and the individual fuel channels. Inspection requirements that developed in feeders in the 1990’s led to rapid development of NDE technology to evaluate feeder integrity. The NDE technology had to deal with the complex and v...
