nowadays, outsourcing is viewed as a trade strategy and organizations tend to adopt new strategies to achieve competitive advantages in the current world of business. focusing on main copmpetencies, and transferring most of activities to outside resources of organization( outsourcing) is one such strategy is. in this paper, we aim to decide on decision maker agent of transportation system, by a...

Dried sphagnum moss was ground using a pin mill and hammer under various operating conditions, i.e., changes in the rotor frequency feed rate. The specific energy consumption of size reduction recorded. powder characterized by median particle size, width distribution (span), loose tapped bulk densities, Hausner ratio. Pin milling used less for than milling, especially when target below 100 μm. ...

Cereal grains are the primary energy source in swine diets. Therefore, not only must producers be concerned about the composition of the grain, but also how it is processed so the pig can fully utilize the nutrients. Because feed represents 65 to 75 percent of overall production costs in a swine operation, improving the efficiency of feed utilization will have a tremendous impact on the cost of...

the benefits of using mineral admixtures as a partial replacement of portland cement (pc) are well established in the literature. economic and environmental advantages by reducing co2 emissions are well known. this paper examines the influence of intergrinding and separate grinding on the amount of energy consumption, blaine fineness and particle size distribution (psd) of blended cements, name...

rice bran is a major by-product of the rice milling process that contains high amounts of fiber, proteins, fats, vitamins, minerals as well as antioxidants and hence can be utilized in enriching food products. the main aim followed in this study was to determine the effects of rice bran of variable particle sizes (53, 125 and 210 µm) and its quantity (0, 5, 10, 15 and 20%) on the quality of bat...

the aim of the present study was to investigate the influence of nozzle configurations on spray drift and explain the influences using several atomization characteristics (length of spray sheet, spray angle, velocity distribution of flow field, fluctuation of velocity, and droplet size). nozzles manufactured by one company (lechler gmbh, germany) were tested by spraying local tap water in a win...
