UNLABELLED Approximately 45%-50% of all duty-related deaths among firefighters are due to sudden cardiovascular events, and a disproportionate number of these fatalities occur after strenuous fire suppression activities. PURPOSE The objective of this study is to evaluate the effect of strenuous firefighting activities on platelets, coagulation, and fibrinolytic activity and to document the ex...
firefighting is extremely strenuous and physically demanding work and involves ability to cope with emergency life-or-death situations. because of the high physical demands of firefighting, successful job performance and minimizing of morbidity and mortality depends on fitness for duty. the firefighting department of tehran does not perform periodic medical assessment for firefighters. the aim ...
OBJECTIVES The primary objective of this study was to document the timeline of physiologic recovery from firefighting activities in order to inform emergency medical services (EMS) of vital sign values that might be expected during incident rehabilitation and in developing rehabilitation protocols to make decisions about when to return personnel to the fireground. Secondarily, we compared two d...
after the soviet union dissolution, a chaotic period was begun in the russia. russia lost its glory and felt disgrace. the first group of elites came to power under yeltsin; they tried to re-define russia’s identity as a european country and build a foreign policy on this baseline. therefore russia tried to become closer with the west especially with the u.s. according to their view the sovie...
application of agent based model in simulation of stakeholder’s behavior is slightly a new method for modeling of complicated systems that include autonomous agents interacting with each other. recent numerical achievements have made the applications of agent based models possible in various fields. these applications range from modeling of human progress and destruction of past civilizations t...
Firefighting is a combinatorial optimization problem on graphs that models the problem of determining the optimal strategy to contain a fire and save as much (trees, houses, etc.) from the fire as possible. We study a new version of firefighting, which we call Politician’s Firefighting and which exhibits more locality than the classical one-firefighter version. We prove that this locality allow...
Whirling disease is a serious problem that impacts wild and hatchery salmonid stocks across the globe. Whirling disease is caused by a microscopic parasite, Myxobolus cerebralis, with a complex life history involving both salmonid and oligochaete worm hosts. In this study, we investigated the capability of wildland firefighting foams to inactivate M. cerebralis by indirect methods. Specifically...
fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...
BACKGROUND Firefighters have increased risk of cardiovascular disease and of sudden death from coronary heart disease on duty while suppressing fires. This study investigated the effect of firefighting activities, using appropriate personal protective equipment (PPE), on biomarkers of cardiovascular effects in young conscripts training to become firefighters. METHODS Healthy conscripts (n = 4...
