Evaluation of Passenger Train Car Materials in the Cone Calorimeter

Recent advances in fire test methods and hazard analysis techniques make it useful to reexamine passenger train fire safety requirements. The use of test methods based on heat release rate (HRR), incorporated with fire modeling and hazard analysis, could permit the assessment of potential hazards under realistic fire conditions. The results of research directed at the evaluation of passenger tr...

Cone Calorimeter – a Tool for Measuring Heat Release Rate

The cone calorimeter is considered the most significant bench scale instrument in fire testing. This apparatus has been adopted by the International Organization for Standardization (ISO 5660-1) for measuring heat release rate (HRR) of a sample. It has been shown that most fuels generate approximately 13.1 MJ of energy per kg of oxygen consumed. Therefore, HRR is based on the fact that the oxyg...

Quality Factor for the Hadronic Calorimeter in High Luminosity Conditions

The Tile Calorimeter (TileCal) is the central section of the hadronic calorimeter of ATLAS experiment of the Large Hadron Collider (LHC) and has about 10,000 eletronic channels. An Optimal Filter (OF) has been used to estimate the energy sampled by the calorimeter and applies a Quality Factor (QF) for signal acceptance. An approach using Matched Filter (MF) has also been pursued. In order to co...

The Role of Chlamydia trachomatis IgG Antibody Testing in Predicting Tubal Factor Infertility in Northern Iran

Background The purpose of this study was to investigate the role of Chlamydia serology as a screening test for tubal infertility and to compare the results with hysterosalpingography (HSG) and laparoscopic findings. MaterialsAndMethods This was a cross-sectional study undertaken on 110 infertile women treated in the IVF Ward, at Emam Khomeini Hospital, Sari, Iran who underwent laparoscopy and H...
