Golda farms and depots of selected areas of the different districts of Bangladesh viz. Khulna, Bagerhat, Jessore and Norial area were sampled for the detection of Salmonella sp. and Escherichia coli. Incidence of Salmonella positive samples was 39%, 25%, 50% and 42% in the farms and 30%, 20%, 20% and 30% in the depots of Dumuria under Khulna, Bagerhat Sadar under Bagerhat, Avoynagar under Jessore and Kalia under Norail district respectively. On the other hand, E. coli positive samples was 23%, 42%, 25% and 17% in the farms and 70%, 30%, 50% and 30% in the depots of Dumuria (Khulna), Bagerhat Sadar (Bagerhat), Avoynagar (Jessore) and Kalia (Norail) region respectively. The overall results indicate that the trend of Samonella and E. coli contamination in farms and depots of all the regions is more or less similar although some variations were observed among the farms and depots of different location and region.

Recently, the interest in the mixed-use development of various urban planning facilities has been increased, but the interest in the Mixed-use development of bus depots that is closely related to our daily life is insufficient circumstance so far. Accordingly, this study aims to realize the necessity for the mixed-use development of bus depots as methods to improve the living environment and use efficiently the land, and to suggest reasonable development directions by analyzing their physical character after classifying bus depots according to their position in the residential area. As the results of study, bus depots have different properties according to their position in residential area and have the problem of space shortage. Also, many things such as location of entrances, the finish method of edge of bus depot's area are affected by the surrounding environment. So development plan to consider the each condition is required.

Anatomically separate fat depots differ in size, function, and contribution to pathological states such as the metabolic syndrome. We isolated pre-adipocytes from different adipose depots, omental, subcutaneous and intramuscular, of beef cattle, and cultured in vitro to determine the basis for the variations and attribute these variations to the inherent properties of adipocyte progenitors. The proliferating cells from all depots before the confluence were harvested and the proteome was analyzed by a functional proteomic approach, involving 2-DE and MALDI-TOF/TOF. More than 252 protein spots were identified, selected and analyzed by Image Master (ver 7.0) and MALDI-TOF/TOF. Further, our analysis showed that there were specific differences in proteome expression patterns among proliferating precursor cells from the three depots. Sixteen proteins were found to be differentially expressed and these were identified as proteins involved in cellular processes, heat shock/chaperones, redox proteins, cytoskeletal proteins and metabolic enzymes. The results also enabled us to understand the basic roles of these proteins in different inherent properties exhibited by adipose tissue depots.

This vehicle scheduling problem with multiple depots and multiple vehicle types (VMM) is to determine the optimal vehicle routes to minimize the total travel costs. The object of this paper is to develope an exact algorithm for the VMM. In this paper the VMM is transformed into a mathematical model of the vehicle problem with multiple depots. Then an efficient branch and bound algorithm is developed to obtain an exact solution for this model. In order to enhance the efficiency, this algorithm emphasizes the follows; First, a heuristic algorithm is developed to get a good initial upper bound. Second, an primal-dual approach is used to solve subproblems which are called the quasi-assignment problem, formed by branching strategy is presented to reduce the number of the candidate subproblems.

The main purpose of this study is to find out the optimal solution of the vehicle routing problem considering heterogeneous vehicle(s), double-trips, and multi depots. This study suggests a mathematical programming model with new numerical formula which considers the amount of delivery and sub-tour elimination and gives optimal solution by using OPL-STUDIO(ILOG). This study also suggests modified genetic algorithm which considers the improvement of the creation method for initial solution, application of demanding point, individual and last learning method in order to find excellent solution, survival probability of infeasible solution for allowance, and floating mutation rate for escaping from local solution. The suggested modified genetic algorithm is compared with optimal solution of the existing problems. We found the better solution rather than the existing genetic algorithm. The suggested modified genetic algorithm is tested by Eilon and Fisher data(Eilon 22, Eilon 23, Eilon 30, Eilon 33, and Fisher 10), respectively.

H maritime company in Korea had a long history of difficulty in obtaining enough empty containers to transport its commodities. Despite efforts to resolve the problem, the repositioning of empty containers between depots was still planned manually, which consumed much worker time. To automate the generation of reposition plans, we developed a planning system to optimize the company's reposition of empty containers between global depots with a linear programming model functioning as a key decision engine in the system. The model determines the route, volume and mode of transportation for repositioning empty containers from depots with surplus containers to those requiring containers, as well as the empty space of ships generated from the unloading or loading of full and empty containers. The system has been in operation in the company's global network since March 2008.

Current of DC traction systems flows from the positive busbar of the substation, through the overhead contact system, to the vehicle, and returns through the running rails. Because the rails are not very effectively insulated from the earth a certain amount of current flows into the earth, especially in the area near the load and depots. At the place where the stray current leaves the rail and pipe, corrosion may take place. In this paper we introduce the electrolytic corrosion protection methods of depots using silicon rectifier for the rail.

Management innovation as a strategic alternative to create competitive advantages in the global market, is being actively progressed by conglomerates such as Samsung, LG and Toyoda as they cut a brilliant figure in the 21 century by using various innovation methods. However, the domestic railway sectors, in particular urban railway depots have neglected management innovation as they undertake Operation and Management in non-competitive settings of a corporate enterprise. This paper analyzes the critical success factors that have switched the most obsolete depots to a benchmark model for domestic railway depots based on the remodeling businesses undertaken in Gunja rolling stock maintenance office, Korea's first urban railway depot, along with 5S 6sigma program.

In order to understand the effects of sex or age on cellular characteristics of adipocytes from Hanwoo and sheep, samples were obtained from omental, subcutaneous, intermuscular and intramuscular adipose tissue depots of bulls, steers, heifers and cows in Hanwoo, and perirenal, omental and subcutaneous adipose tissues of fetal lambs, suckling lambs and wethers in sheep. In case of Hanwoo, mean diameter, surface area and volume of adipocytes from each depot were obtained by multisizer II (Coulter Co., UK). Osmium-fixed adipocytes were sized and counted using $560{\mu}m$ aperture. For samples obtained from sheep, cellularity was measured by using microscope and MCV program of Texas Instrument. Bulls had less subcutaneous and kidney fat than steers even though their slaughter and carcass weight were heavier. The amounts of fat from cows were greater in subcutaneous, kidney and internal organs than heifers. Steers had larger adipocytes in subcutaneous, intermuscular and intramuscular adipose tissues than bulls, although the differences were significant only for the subcutaneous adipose tissue depots. Adipocytes appeared to be largest in omental and smallest in intramuscular adipose tissue, although there were no significant differences among tissues. In a comparison of heifers and cows, significant site effects (p<0.05) were shown in adipocyte diameter, surface area and volume, and adipocyte appeared to be largest in omental tissue. Statistical difference (p<0.05) was only shown in cell volume of intramuscular tissue which was higher in cow than heifer. Intramuscular adipose tissue tended to have relatively greater numbers of cells per gram tissue and reflect lesser maturity of intramuscular adipose tissue relative to other adipose tissues. In sheep, regardless of adipose tissue depots, wethers had the greater adipocyte diameters than those at any other growth stage of sheep. Within adipose depots, the ranking of cell size was the greatest in the omental tissue of wether and the lowest in the renal and subcutaneous adipose tissue depots of fetal lamb. The cell size of adipocyte became larger with age, especially from fetal to suckling lamb due to a rapid hypertrophy of both perirenal and subcutaneous adipocytes during the suckling period.
