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...
It is well-known that the architecture of macromolecules plays an important role in hydrodynamics and viscosity its semi-diluted solutions. However, systematic study rheology with complex topology, such as microgels, remains a difficult task. In this work, we use computer simulations methods non-equilibrium molecular dynamics to viscous properties randomly cross-linked microgels compare it mult...
this study explored the nature of transfer among bilingual vs. trilinguals with varying levels of competence in english and their previous languages. the hypotheses were tested in writing tasks designed for 75 high (n= 35) vs. intermediate (n=40) proficient efl learners with turkish, persian, english and persian, english linguistic backgrounds. qualitative data were also collected through some ...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
In this paper we review optical methods suitable to generate and to detect elastic waves in solids without any mechanical contact. The mechanisms underlying elastic wave generation by the impact of a pulsed laser beam are outlined. The principles of optical techniques able to detect surface displacements of amplitude less than one angstrom are described. Examples of applications in domains such...

this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
background: recto-vaginal colonization of group b streptococcus (gbs) has been known as an important issue in mother and newborn’s health, which is getting frequent in developing countries. screening test have been introduced and utilized in many countries and is recommended by many researchers. however, due to lack of information in prevalence of gbs, especially in iran, there are doubts and c...
objective: cardiopulmonary resuscitation (cpr) has been known in its present form since 1960. different studies have reported variable outcomes among different countries. therefore, the purpose of this study was to assess the rate of cpr success and the survival rate in managing cardiac arrest among patients in an educational medical center. methods: this cross-sectional study was performed at ...
