This paper studies multiple cross-dockings where the loads are transferred from origins (suppliers) to destinations (customers) through cross-docking facilities. Products are no longer stored in intermediate depots and incoming shipments are consolidated based on customer demands and immediately delivered to them to their destinations. In this paper, each cross-docking has a covering radius tha...

background and aims: internet addiction is one of the problems emerged with the development of technology. considering the potential negative effects of internet addiction on health, the present study aimed to determine the prevalence of internet addiction in university students in ilam, west of iran, in 2014. methods:in this cross– sectional study, 1066 university students in both public and ...

low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. this study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. in order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyc...

banana xanthomonas wilt is a systemic disease of banana plants. we investigated the risk of spreading xanthomonas campestris pv. musacearum (xcm) through asymptomatic mature bunches. samples of banana fingers and rachis from markets within kampala, uganda and at border points of uganda with dr congo, tanzania, rwanda and kenya were tested for the presence of xcm through recovery of the bacteriu...

this paper explores the effects of general and agricultural trade openness on economic freedom and alongside with the quality of institutions, on income and poverty. recent cross-country data for over 200 nations in global regions were used to estimate equations for income, poverty and economic freedom. economic freedom appears to have positive impacts on income levels, which together with good...

background: lipase is an enzyme with immense application potential. ester synthesis by lipase catalysis in organic media is an area of key industrial relevance. enzymatic preparations with traits that cater to the needs of this function are hence being intensely researched. objective: the objectives of the study were to immobilize the lipase from bacillus sp. ps35 by cross-linking and adsorptio...

background vermilion irregularities are common secondary deformities after cleft lip repair, regressed or resected hemangiomas, trauma and tumor surgeries. vermilion deficiency attracts considerable attention and detracts from an otherwise excellent lip repair. minor and moderate vermilion defects can be corrected with upper lip advancement, rotation flaps, tongue flaps or grafts. major defects...

a lab-scale cross flow membrane bioreactor (cf-mbr) was operated to determine the biokinetic coefficients under mlss concentrations of 5000 and 3000 mg/l. the investigation showed that the yield (y), the endogenous decay coefficient (kd), the maximum specific growth rate (μm) and the saturation constant (ks) were 0.276 mg/mg, 0.07 /day, 0.653 /day, and 396.62 mg cod/l respectively for mlss 5000...
