BACKGROUND To assess the health impact of air pollution on Bejaia population in the north of Algeria, we carried out a descriptive epidemiologic inquiry near the medical establishments of three areas. METHODS From hospital admissions registers, we collected data on the hospital mortality and admissions relating to the various cardiorespiratory pathologies generated by this type of pollution. ...

This case report is about a 62 year old woman who was involved in an accident while driving her car, during which the driver side air bag deployed. She experienced intense anterior chest pain that radiated to her left arm after the accident, but was otherwise well; there was no significant medical history. An electrocardiogram done one and half hours after admission revealed 1 mm ST segment ele...

The challenge for Automobile is present emission norms that demands engine for green environment with high performance and low emission. The Low Heat Rejection Engine (LHR Engine) is a technology, which minimizes heat loss to the coolant by providing heat resistance in the heat flow to the coolant. As LHR Engine is used, the heat is not transferred to the surroundings. Another method to improve...

The automobile car cabin is complex man –machine interface. Two main goals of Heating Ventilation and Air conditioning System is providing thermal comfort and save energy. Comfort is a subjective feeling and hard to model mathematically. This is because thermal comfort is influenced by many variables such as temperature, relative humidity, air velocity and radiation. Aim of this paper is to des...

The purpose of this investigation was to validate a new system of breath-bybreath expired gas analysis to both an artificial working model of lung ventilation and gas exchange as well as to the Douglas bag technique. In addition, comparisons will be made between expired fractions, ventilation, and computations of VO2, VCO2, and RER between the new system and a commercial mixing chamber system (...

Inflation and oesophageal pressures were recorded simultaneously during bag and mask resuscitation of 9 asphyxiated babies. After half a minute of standard inflation pressures, higher pressures were applied for at least 5 inflations by occluding the blow-off valve. No air entered the oesophagus until a high mean inflation pressure of 5.4 kPa was exceeded. These findings were confirmed in 4 fres...

We have sought to accurately quantify automobile HVAC air flow rates in four passenger vehicles, under a range of different ventilation settings and speeds. We used Sulphur Hexafluoride (SF6) as a tracer gas, coupled with a portable doser/sampler system to quantify flow rates and leakage. Results of this work indicate a linear increase in HVAC air flow rate with increasing vehicle speed for all...
