risk assessment and management of petrochemical feed and product transportation pipelines is very important to preventing probable accidents. so, 60 pipelines evaluated by chemical exposure index and chlorine pipeline due to high hazard distances selected for relative risk analysis. the chlorine pipeline with 3468 meter length divided to 100 meter sections, and third party damage index (tpdi), ...

according to the famous theory in iranian jurisprudence, civil liability of the vehicle keepers against third party is on the res ipsa loquitor, duty of care, or risk, or a combination of them. regarding to these foundations, if a vehicle keeper has not a policy of insurance covering third party damage, he or she must compensate the damage although has not caused the accident. this was inferenc...

Focusing on the diversity, complexity and uncertainty of the third-party damage accident, the failure probability of third-party damage to urban gas pipeline was evaluated on the theory of analytic hierarchy process and fuzzy mathematics. The fault tree of third-party damage containing 56 basic events was built by hazard identification of third-party damage. The fuzzy evaluation of basic event ...

This article discusses technology integration literature used to guide the design and implementation of a technology professional development intervention (TPDI) for secondary education teachers. Qualitative multiple-case research methods were used to examine teachers’ perceptions of the TPDI factors to provide a deeper understanding of which factors teachers’ perceived to be beneficial to the ...

We present convergent-close-coupling CCC calculations of the angular anisotropy parameters 2 , 4 and the recoil ion momentum distribution d /dp in two-photon double ionization TPDI of helium. In a stark contrast to single-photon double ionization SPDI , where the 2 parameter varies widely changing the angular distribution from isotropic to nearly dipole for slow and fast photoelectrons, respect...
