this paper addresses a reliable facility location problem with considering facility capacity constraints. in reliable facility location problem some facilities may become unavailable from time to time. if a facility fails, its clients should refer to other facilities by paying the cost of retransfer to these facilities. hence, the fail of facilities leads to disruptions in facility location dec...
Background: The aim of this study was to formulate and evaluate the noble herbal moisturise gel containing Stevia extract. Methods: The cosmetic gel formulation was designed by using aqueous extract of Stevia rebaudiana leaves in varied concentrations (2.5% and 5.0%) and evaluated using physiological measurements in comparision with a control placebo gel. The initial physicochemical parameters ...

objective(s): irinotecan is a potent anti-cancer drug from camptothecin group which inhibits topoisomerase i. recently, biodegradable and biocompatible polymers such as poly lactide-co-glycolides (plga) have been considered for the preparation of nanoparticles (nps). materials and methods: in this study, irinotecan loaded plga nps were fabricated by an emulsification/solvent diffusion method to...
this study focuses on the optimization of the plane structure. sequential quadratic programming (sqp) will be utilized, which is one of the most efficient methods for solving nonlinearly constrained optimization problems. a new formulation for the second order sensitivity analysis of the two-dimensional finite element will be developed. all the second order required derivatives will be calculat...
background: environmental problems of the plastic materials used in food packaging and the demand for food quality improvements lead to the development of packaging in natural materials. edible films such as calcium alginate extend the shelf life by acting as a selective barrier against moisture and oxygen. the main objective of this study was to explore a calcium alginate based edible film to ...
A meshless approximation and local integral equation (LIE) formulation are proposed for elastodynamic analysis of a hollow cylinder made of quasicrystal materials with decagonal quasicrystal properties. The cylinder is assumed to be under shock loading. Therefore, the general transient elastodynamic problem is considered for coupled phonon and phason displacements and stresses. The equations of...
background: considering to the high distribution of cockroaches as urban pests, the efficacy of different formulations of metarhizium anisopliae strain iran 437c were assessed against the brown-banded cockroach, supella longipalpa f. under laboratory and field conditions. methods: metarhizium anisopliae isolates were screened with immersing adults of the brown-banded cockroachs in aqueous sus...
double emulsion solvent evaporation technique is one of the most attractive methods used to prepare micro and nanoparticles in pharmaceutical areas of interest, but because of the effects of many formulation factors on the size and release behavior of the fabricated particles, optimization of the formulation factors is needed. in this study various parameters including technical and composition...
