This paper integrates competitive pricing and network design problems for the short life cycle products. The pricing problem determines selling prices of the products for different life cycle phases in a competitive market, as well as acquisition management of returned products. Besides, the selling and acquisition prices are related to the distance between distribution centers and customers. T...

VIDENCE for an effect of the transferrin locus on some aspect of fitness has E been presented for cattle (ASHTON 1958, 1965; ASHTON and FALLON 1962), pigs (KRISTJANSSON 1964; SMITH et aE. 1968), poultry (MORTON et al. 1965), and tuna (FUJINO and KANG 1968). TAMARIN and KREBS (1969) have reported that one Tf allele is at an advantage when natural populations of Microtus are declining in numbers....

In this paper we look at the implications of an emerging technology for the case in favor of, or against, postmenopausal motherhood. Technologies such as in vitro derived gametes (sperm and eggs derived from nonreproductive cells) have the potential to influence the ways in which reproductive medicine is practiced, and are already bringing new dimensions to debates in this area. We explain what...

introduction: food industry is one of the most important industries in developing countries that has an enormous role in employment, export and value added of the agricultural sector. iran as a developing country has a comparative advantage in food product industries for several reasons such as adequate and cheap raw materials and having several companies in the field of food industries. the fo...

Abstract Purpose The primary objective of this study was to evaluate the environmental impact and financial cost repairing surgical scissors. Methods We used life cycle assessment (LCA) analysis estimate impacts functional unit one use a reusable scissor (manufactured in Germany UK), three baseline scenarios were compared: no repair, onsite (hospital), offsite (external contract) repair. This ‘...

Recently, immigration and its socio-economic aspects have been in the centre of European Union leaders’ agenda. In this paper, we apply National Transfer Accounts (NTA) methodology to calculate complete set NTA results for immigrants natives five EU countries. We find that due lower labour income, which cannot be offset by consumption, experience a shorter independence period much aggregate lif...

Physical properties (density in kg m-3, viscosity, sinking rates and dispersion rate) of the gametes and associated spawned materials were measured for three species of sea urchin, Tripneustes gratilla, Echinometra mathaei and Colobocentrotus atratus, from habitats that differ in wave exposure. The gametes of all three species are negatively buoyant, highly viscous and exhibit shear-thinning (a...

in this research we have presented a local model for implementing systems engineering activities in optimized acquisition of electronic systems in electronic high-tech industrial. in this regard, after reviewing the literature and the use of documents, articles and latin books, we have collected system acquisition life cycle models from different resources. after considering the criteria of the...
