Centralizing and using proper transportation facilities cut down costs and traffic. Hub facilities concentrate on flows to cause economic advantage of scale and multimodal transportation helps use the advantage of another transporter. A distinctive feature of this paper is proposing a new mathematical formulation for a three-stage p-hub location routing problem with simultaneous pick-ups and de...
BACKGROUND The biological diagnosis of sphingolipidoses currently relies on the measurement of specific enzymatic activities and/or genetic studies. Lysosphingolipids have recently emerged as potential biomarkers of sphingolipidoses and Niemann-Pick type C in plasma. METHODOLOGY We developed a sensitive and specific method enabling the simultaneous quantification of lysosphingolipids by LC-MS...

Vehicle routing problems have various extensions such as time windows, multiple vehicles, backhauls, simultaneous delivery and pick-up, etc. The objectives of all these problems are to design optimal routes minimizing total distance traveled, minimizing number of vehicles, etc that satisfy corresponding constraints. In this study, an ant colony optimization based heuristic that can be used to s...
This paper investigates a pricing multi-period, closed-loop supply chains (CLSCs) with two echelons of producers and customers. Products are delivered to customers might be defective which are picked up and gathered in the collection center and will be fixed if it is possible and will be returned to the chain. Otherwise, they are sold as waste. This problem is determining price and distributio...
nieman-pick disease type c is a rare, autosomal recessive, neurometabolic disorder associated with the accumulation of unesterified cholesterol in lysosomes and late endosomes. because of multiple organ involvement and wide range of clinical manifestations, these patients will demand multiple diagnostic and therapeutic procedures requiring anesthesia. sincepathogenesis of this disease is still ...
تصمیمگیری در روابط عاشقانه مثل شروع یک دوره آشنایی، پیشنهاد ازدواج یا پایان دادن به یک رابطه میتواند عواقب درازمدت و مهمی داشته باشد. هدف پژوهش حاضر بررسی اثر بخشی آموزش قبل از ازدواج به شیوه برنامه آگاهی و انتخاب های بین فردی (PICK) بر تصمیم گیری دانشجویان مجرد بود. پژوهش حاضر نیمه آزمایشی با طرح پیش آزمون و پس آزمون با گروه کنترل بود. 36 دانشجوی مجرد بر اساس نمره یک انحراف معیار پایین ...
