in order to lighten the prestressed concrete solid members, nowadays, it is possible to make use of the advantage of hpc (fc'>60 mpa) as well as replacing the solid section with a psc thin-walled section for certain members such as circular and box columns. using the strength theory of aci, a numerical procedure along with a computer program was developed for the analysis of such sections ...

low grade diasporic bauxite in the jajarm mine with an a/s (al2o3/sio2) ratio of 2.3 is not usable in the bayer process at jajarm alumina complex. due to the severe interlocking effect between the diaspore and aluminosilicate minerals (chamosite and kaolinite) and iron-containing minerals in a microcrystal matrix, the thermo-chemical treatment, which is independent from micro-mineralogy, was ch...

as claimed by many behavioral scientists, designing should be based on the knowledge of interaction between human and environment. environmental quality is also created in the context in which humans interact with their environment. to achieve such quality, designers should develop appropriate models for explaining this relationship, and this requires an understanding of human nature and the en...

in order to determine the effect of potassium silicate solution with elements of macro and micro elements on agronomic traits of rice, tarom, a field experiment in paddy fields galogah city - village marbles of the crop year 2014 was conducted. the results showed that the highest plant height (013/180 cm) to 2 liters per hectare and no interaction effects of potassium silicate elements. the res...

signs and symptoms of d ph toxicity were seen in an epileptic child who had received dph and mp concurrently. in the absence of liver and kidney disease and any intercurrent infection, and with the patient's recovery following the withdrawal of dph, it appears that drug-drug interaction is the most logical explanation for dph intoxication.

in this article, thanks to phenomenological approach, an attempt is made to account the correlation between globalization and neo-regionalism. in the process, the finding of this scholar convinced him to reject antithetical correlation between the two. instead, he argues neo-regionalism is and ecopolitical current to adjust globalization. in the final analysis, it is argued both currents are re...

We consider the interaction of quantum light with an ideal semiconductor microcavity. We investigate photon statistics in different conditions and the presence of detuning and exciton-exciton interaction. We show that in the resonant interaction and absence of the exciton-exciton interaction, the state of the whole system can be considered as   coherent state. According to our results, it turns...
