The Isotope Magnet Experiment (ISOMAX), a balloon-borne superconducting magnet spectrometer, was designed to measure the isotopic composition of the light isotopes (3 Z 8) of cosmic radiation up to 4 GeV nucleon 1 with a mass resolution of better than 0.25 amu by using the velocity versus rigidity technique. To achieve this stringent mass resolution, ISOMAX was composed of three major detector ...

In this contribution Artificial Neural Network (ANN) modeling of the hydrocracking process is presented. The input–output data for the training and simulation phases of the network were obtained from the Tehran refinery ISOMAX unit. Different network designs were developed and their abilities were compared. Backpropagation, Elman and RBF networks were used for modeling and simulation of the hyd...

Hydrocracking is an important secondary process in the petroleum industry, generally used to process heavy oil cuts. The process is tailored to various needs of refineries in order to maximize middle distillates, gasoline, LPG and similar products. Therefore, kinetic modeling of hydrocracking reactors applied to upgrade vacuum heavy oil (Isomax) is important and needs to be investigated. In thi...

OBJECTIVES Pieces of evidence have been accumulating that imply a crucial role of angiotensin II (Ang II) in initiation and progress of heart failure, but the signalling processes subsequent to Ang II receptor activation in cardiac myocytes are complex and still controversial. We examined the effects of Ang II on the relationship between the intracellular Ca2+ transient and isometric contractio...

noise interference with employee’s speech communication is considered as one of the noise pollution effect in any workplace. these interferences can disrupt communication of necessary and vital data between individuals. and as a result can cause anything from a slight irritant to a serious safety hazard involving accident or even fatality. this study was focused on the analysis of the human err...

The research described in this study focuses on the innovation and optimization of building envelope panels with integrated energy-active elements thermal barrier function. It is closely related to developing implementing prototype prefabricated house IDA I combined building-energy systems using renewable energy sources. We were inspired by patented ®ISOMAX panel system, which we have been rese...
