Measurements of air humidity, temperature, carbon dioxide (CO2), respirable particles, ozone, nitrogen dioxide (NO2), formaldehyde, and volatile organic compounds of possible microbial origin (MVOC) were performed during 26 flights with Boeing 767-300. The mean temperature in cabin was 22.2 °C (range 17.4-26.8 °C), and mean relative air humidity was 6% (range 1-27%). The CO2 during cruises was ...

AIM The aim of this study was to describe and compare the self-assessed occupational health among female nurses, cabin crew and teachers, in relation to their working environment. BACKGROUND Similarities between the three occupations, i.e. predominantly female and service-oriented, render them interesting in comparison with respect to health and working environment. METHODS The participants...

In this paper, a study of the concurrent engineering design for the environmental friendly low cost aircraft cabin simulator is presented. The study describes the used of concurrent design technique in the design activity. The simulator is a testbed that was designed and built for research on aircraft passenger comfort improvement of long haul air travel. The simulator consists of an scale down...

Several dramatic accidents have emphasized certain deficiencies in cockpit-cabin coordination and communication. There are historical, organizational, environmental, psychosocial, and regulatory factors that have led to misunderstandings, problematic attitudes, and suboptimal interactions between the cockpit and cabin crews. Our research indicates the basic problem is that these two crews repre...

For D-glucose and analogs there are two distinct phosphotransferase enzymes II with different specificities. Transport and chemotaxis were studied in E. coli mutants having only one or the other of these two enzymes. It was found that the transport specificity of a given enzyme II correlates with taxis specificity, and mutational loss of an enzyme II abolishes taxis toward only those sugars whi...

Occupational exposure to oil fumes, organophosphates, halogenated flame retardants, and other volatile semi-volatile contaminants is a concern within the aviation industry. There no current consensus on risk attributed these chemical classes aircraft cabin. Contaminant concentrations rarely exceed conventional air quality guidelines, but concerns have been raised about guidelines' applicability...

BACKGROUND With the widespread availability of non-invasive imaging of the brain in an aging population, we are increasingly confronted with the problem of the incidental discovery of unruptured aneurysms. The management of these patients remains controversial. Endovascular treatment can prevent rupture, but involves immediate risks. Furthermore, successful treatment does not eliminate all risk...

Pseudoaneurysms of the superficial temporal artery are rare and may be treated by manual compression, surgical intervention, coil embolization, or percutaneous thrombin injection. We present a novel technique of local ultrasound guided low-profile coil embolization of the superficial temporal artery with both satisfactory cosmetic and surgical results.
