    The use of cooling systems has increased because of drastic changes introduced after the oil revolution in the local architecture by using modern building designs and practices that may not suit Oman's climate. The traditional architecture in this country is characterized by its passive cooling design features, which the Locals fine-tuned through trial and error. These sustainable passive design practices developed over the ages have the ability to provide healthy and comfortable spaces for their occupants while preserving the environment and natural resources. These strategies are still evident in many traditional settlements and buildings in Oman. The present research evaluates the effect of natural ventilation in achieving thermal comfort in traditional Omani houses. For this purpose, a traditional house in a hot-arid climate zone with vernacular architecture typology was chosen as a case study. Computational Fluid Dynamic (CFD) was used to model the house and analyse the airflow and temperature levels in its spaces. The results show the efficiency of such a design to enhance natural ventilation and thermal comfort in similar geo-climatic regions

    Depression in primary care: difficulties and paradoxes

    Get PDF
    The presentation of depression in primary care is in many ways different from that seen in psychiatric settings. The process of detection and treatment is also different. This is particularly so in developing countries like Pakistan, which has high prevalence rates of depression but poorly organized primary health care services and primary care physicians (PCPs) who have little psychiatric training, either at undergraduate or postgraduate levels. There is a need to review difficulties faced by primary care physicians in detection and management of depression. It is hoped this would lead to better and more effective management of depression at primary health care level
