today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
BACKGROUND IV delivery of volatile fluorinated anesthetics has a number of potential advantages when compared with the current inhalation method of administration. We reported previously that the IV delivery of sevoflurane can be achieved through an emulsion composed of a linear fluorinated diblock copolymer, a stabilizer, and the anesthetic. However, this original emulsion was subject to parti...
abstract the purpose of this study was to find out the effect of applying the principles of group-dynamic assessment (g-da) on learning of conditional structures in english by iranian efl learners at the intermediate level, which according to the formal educational system in iran, includes students who are in their second year of studying in high schools of koohdasht city. this study was a qua...
objective(s):investigation of phase diagram of various drug formulations is effective to predict different phase region of drugs to detect final formula. the purpose of this research was to develop the ternary phase diagrams for a drug microemulsion system consisting of cucurbita pepo (pumpkin) oil, surfactant (tween 80) and deionized water. materials and methods:an electrical conductivity was ...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
In this study, the effect of basil seed gum (BSG) on the stability and rheological properties of egg white albumin (EWA) emulsions was investigated. A constant amount of EWA (0.5% w/v) and different concentrations of BSG (0-0.3% w/v) were used for the manufacture and stabilization of oil-in-water emulsions (30% w/w). The results showed that by increasing BSG concentration, the storage (21 days)...
the present dissertation aims to investigate four-word lexical bundles in applied linguistics research articles by iranian and internationally-published writers. the aims of this study are two-fold: first of all, attempts have been made to create a comprehensive list of the most commonly used four-word lexical bundles categorized by their type and token frequency, their structural characteristi...
many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...
we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.
By using SMA resins as a polymeric surfactant in an emulsion polymerisation process, alone or in combination with other surfactants, the stability of the dispersion under different kinds of stress (chemical, high shear or freeze/thaw) is significantly improved. The presence of SMA copolymer, adsorbed at the surface of the particles of an acrylic dispersion, enhances the stability of the latex b...
