the genetics and mechanism of malathion resistance in the adults of an. stephensi (ban-s), was studied. nine successive generations of malathion selection in the adults resulted in an increase in ltso of about 3-fold. the crossing experiments indicated that the resistance is inherited as partially dominant character with no indication of sex linkage. the results of back-crosses suggested that p...

heart failure (hf) is a common disease with high health care costs and high mortality rate knowledge of the health-related quality of life (qol) outcomes of hf may guide decision making and be useful in assessing new therapies for population. yet little is known about qol of hf patients in iran. objectives: to assess health related qol of patients with hf with two different instrument and to co...

interspecific hybridization occurs among cucurbia species it is commonly used for grafting, yield increasing and production of pest resistant rootstocks. in the present research probability of interspecies hybrid generation among seven lines of cucurbita pepo (p1, p4, p5, p6, p10, p22, p25) and six lines of cucurbita moschata (mo3, mo5, mo6, mo9, mo11, mo12) were investigated. after crossing of...

abstractin the last step of desolvation method for preparation of albumin nanoparticles, glutaraldehyde (ga) is added to stabilize the newly formed nanoparticles. due to undesirable effects of ga, the objective of this study was to evaluate alternative methods of crosslinking including ultraviolet (uv) irradiation, adding of glucose and combination of both methods. the nanoparticles were prepar...

in this study, a cross-docking system is designed at strategic and tactical levels. for making the strategic decisions, a multi-objective nonlinear location allocation model for cross-docks is presented based on a distri-bution location allocation model by andreas klose and andreas drexl. the model is further developed to in-clude the whole supply chain members and the objective functions are w...
