Depression is a highly prevalent disorder that causes much personal distress and difficulties in functioning at home and the workplace. In the workplace, as elsewhere, depression can manifest as a variation in normal mood, as a symptom, as a disorder or as a disease. In this study we aimed to investigate the determining factors that affect the depression state among official workers. Workers from two tax offices were chosen through random sampling from the 62 tax offices in Istanbul. We used a q

Located within the borders of a conservation development plan, a traditional street structure, a renovated street structure which holds traditionalism and modernism together and a modern street structure constructed within the present settlement have been studied comparatively to determine the degree to which the existing urban structure meets the expectations of today`s people.

This article concerns an investigation of the full scale evacuation of a building with a configuration similar to that of the World Trade Center (WTC) north tower using computer simulation. A range of evacuation scenarios is explored in order to better understand the evacuation of the WTC on 11 September 2001. The analysis makes use of response time data derived from a study of published WTC survivor accounts. Geometric details of the building are obtained from architects` plans while the total

The vortex behavior and thickness of the nozzle fluid layer of pulsating jets under a ceiling are studied using the laser-assisted visualization technique. The vortex formation characteristics of jets pulsating at different frequencies are compared with those of continuously issuing jets to investigate the effects of the pulsating frequency on the thicknesses of the nozzle fluid layers under a ceiling. To identify similarities between the features of pulsating isothermal jets and periodically pu

Ignition has been systematically, scientifically studied for about a century now. But the development of knowledge in this area has been uneven, and while an advanced understanding has been reached in some areas, knowledge is scant in others. A review of the literature of the field indicates that the following are some of the notable areas where engineering calculation methods are poor or lacking: hot-surface ignition of liquids; ignition of liquid sprays or aerosols; ignition of solids from hot
