one of the most important extensions of the capacitated vehicle routing problem (cvrp) is the vehicle routing problem with simultaneous pickup and delivery (vrpspd) where customers require simultaneous delivery and pick-up service. in this paper, we propose an effective ant colony optimization (eaco) which includes insert, swap and 2-opt moves for solving vrpspd that is different with common an...

background: cesarean section delivery can lead to much maternal morbidity. different cytokines have been reported to be influenced by the mode of delivery. objective: to investigate the influence of mode of delivery on maternal, placental and cord sera of interferon gamma (ifn-γ), interleukin-4 (il-4) and interleukin-10 (il-10) levels. methods: these three cytokines were measured using elisa in...

although the subject of a lease contract is the benefits of property, according to the gradual essence of the benefits, the delivery is also possible in a gradual manner after coming into existence. therefore, the delivery of the benefits is under the general rule of delivery. this means that the loss and defect after the delivery is not considered as loss and defect after the handing in of and...

objective(s): we aimed to investigate the influence of transient receptor potential channel 3 (trpc3) on lipopolysaccharide-induced (lps) preterm delivery mice. materials and methods: mice were randomly assigned to the four groups: an unpregnant group, a mid-pregnancy group (e15), a term delivery group, and an lps-induced preterm delivery group (intraperitoneal injection lps at 15 days). uterin...

abstract background: many factors have been mentioned to influence decision‑making for different kinds of delivery. decision‑making for vaginal delivery is under the influence of culture, perceptions, beliefs, values, attitudes, personalities, and knowledge. the current study aims at exploring the determinants of decision‑making for vaginal delivery in the north of iran from women’s perspective...

background: cesarean section (c-section) in the north of iran accounts for 70% of childbirths, which is higher than the national average of 55%. understanding women’s perceptions towards modes of delivery in different cultures can pave the way for promoting programs and policies in support of vaginal delivery. we aimed to investigate women’s perceptions towards modes of delivery in the north of...

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...
