A bi-criteria optimization is considered whose objectives are the maximization of the load sustained by a structure and the minimization of the structure's volume. As the objectives are conflicting, the solution to the problem is of the Pareto type. The problem is elaborated for a thin-walled column of cruciform cross-section, prone to flexural and torsional buckling. A numerical example is als...

 ABSTRACT Background: The current practice to measure RV is either by BPG or helium dilution methods which may not be available in all clinics due to their cost. Methods: This paper outlines a method for both direct and indirect calculation of RV via PFT with acceptable sensitivity (81 %, 60% ), specificity (71 %, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respect...

objective(s):growing evidence indicates that extract of ginkgo biloba (egb) attenuates hippocampal-dependent memory deficit in aged individuals; however, very little is known about the effect of egb on the structure of hippocampus. therefore we examined the egb-induced morphological changes of the cornu ammonis (ca) region in aged rats. materials and methods: sixteen aged male wistar rats, 24 m...

the incidence and hematological effects of helminth infection during pregnancy were investigated among pregnant women in isiala, mbano, southeast nigeria.totally 282 pregnant women were enlisted for the study between october 2011 and september 2012. stool samples were examined for intestinal helminths using formalin-ether sedimentation technique. hemoglobin (hb) and packed cell volume (pcv) lev...

the present study was undertaken to compare the in hospital results of coronary artery bypass graft (cabg) with (on pump) or without (off pump) cardiopulmonary bypass (cpb). data were collected on all first-time isolated cabgs with saphenous vein and/or artery grafts at shahid madani hospital in tabriz-iran, between 2006 and 2009. age and clinical profile were marched between on pump and off pu...

in this article cuo/water nanofluid was synthesized by using polyvinylpyrolidone (pvp) as the dispersant.  thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. to study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different ph values and pvp surfactant concentrations; also thermal conductivity...
