relief wells are used extensively to relieve excess hydrostatic pressure in pervious foundation strata overlain by impervious top strata, conditions which often exist landward of levees and downstream of dams and hydraulic structures. placing well outlets in below-surface trenches or collector pipes helps dry up seepage areas downstream of levees and dams. relief wells are often used in combina...

In this paper, a newsboy model is developed under uniformly distributed lead-time and demand that is an appropriate assumption in obtaining optimal relief inventory of humanitarian disasters. It is noteworthy that limited historical data are in hand on relief operations. Hence, analytical and approximate solutions for optimal relief order quan­tity were derived. The effect of lead-time uncertai...

Arsenate, an uncoupler of oxidative phosphorylation, relieved the Crabtree effect in Ehrlich-Lett réhyperdiploid ascites tumor cells. Respiration was measured with an oxygen electrode. High arsenale concentrations (30 to 60 ITIM)were needed to produce a 2-fold increase in the depressed respiratory rate. Arsenate concentrations below 10 HTMhad little or no effect. The relief by arsenale was rev...

occurrence of natural disaster inflicts irreparable injuries and symptoms on humans. in such conditions, affected people are waiting for medical services and relief commodities. thus, quick reaction of medical services and relief commodities supply play important roles in improving natural disaster management. in this paper, a multi-objective non-linear credibility-based fuzzy mathematical prog...

abstract background and objective: pain relief during labour is an important determinant of a women’s birth experience. there are numerous pain relief techniques which can be used either with or without pain medication. the aim of our study was to compare the effect of remifentanil alone and its effect in pain relief while using with ketamine during labour. methods: after obtaining informed con...
