Introduction: In female rats sensitivity to antinociceptive treatment varies during estrous cycle stages. The role of GABA through GABAB receptor in nociception has been established. The aim of the present study is to investigate the effect of intercerebroventicular injection of GABAB receptor agonist (baclofen) and GABAB antagonist (CGP35348) on pain sensitivity during different stages of estr...

combined cycle performance can be improved by improving the performance of gas turbine based topping cycle. amongst various options the effective cooling of gas turbine blade for realizing the higher turbine inlet temperatures is one of the attractive options. the present paper deals with the thermodynam-ic analysis of advanced technology gas/steam combined cycle based power plant having closed...

multidimensional modelling of open-cycle process of om355 engine was developed. calculations for computational mesh were carried out. the results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. results included pressure, temperature, emission and rate of heat rele...

The purpose of this paper is multi-objective optimization of refrigeration cycle by optimization of all components of the cycle contains heat exchangers, air condenser, evaporator and super-heater. Studied refrigeration cycle is compression refrigeration cycle of unit 132 Third refineries in south pars that provide chilled water for cooling refinery equipment's. Cycle will be performed by t...

A special class of cubic graphs are the cycle permutation graphs. A cycle permutation graph Pn(α) is defined by taking two vertex-disjoint cycles on n vertices and adding a matching between the vertices of the two cycles.In this paper we determine a good upper bound for tenacity of cycle permutation graphs.

solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23. a statistical analysis was performed to obtain their relationship with sudden storm commencement (sscs) and forbush decrease events (fd) of cosmic ray intensity. an 11-year cyclic variation ...
