background: depression is a kind of sorrow that decreases the level of juiciness. most studies have maintained that psy­chological risk factors have the most profound effect on the development of postnatal depression (pnd). we compared the postnatal depression among the women with elective caesarean and vaginal delivery.  methods: this cross- sectional study was carried out on 120 women 1-4 mon...

this paper addresses a production and outbound distribution scheduling problem in which a set of jobs have to be process on a single machine for delivery to customers or to other machines for further processing. we assume that there is a sufficient number of vehicles and the delivery costs is independent of batch size but it is dependent on each trip. in this paper, we present an artificial imm...

This article develops an integrated JIT lot-splitting model for a single supplier and a single buyer. In this model we consider reduction of setup time, and the optimal lot size are obtained due to reduced setup time in the context of joint optimization for both buyer and supplier, under deterministic condition with a single product. Two cases are discussed: Single Delivery (SD) case, and Multi...

This paper addresses the Vehicle Routing Problem with Delivery Time Cost. This problem aims to find a set of routes of minimal total costs including the travelling cost and delivery time cost, starting and ending at the depot, in such a way that each customer is visited by one vehicle given the capacity of the vehicle to satisfy a specific demand. In this research, a hybrid metaheuristic approa...

Background: Focused ultrasound surgery (FUS) is a novel noninvasive surgery that results in localized tissue necrosis without any breech of the skin or other body orifice. MRI guidance provides anatomic visualization and real time thermal feedback. Our goal is to safely extend this therapy to women who desire future pregnancies. Materials and Methods: We have undertaken 4 multisite trials of FU...
