Saat ini banyak kalangan yang memiliki kendaraan impian harganya terjangkau dengan kemampuan keuangan mereka. Namun masyarakat tidak mengetahui cara mengantisipasi dan mencegah secara dini kerusakan dari mobil diakibatkan berfungsinya sistem radiator pendingin mesin. Dibuat memonitor suhu air normal sesuai kerja disyaratkan pabrikan mengatasi overtemp mendadak dapat diatasi mobil. Sistem akan m...
Power series expansions in ka are derived for the pressure at the edge of a radiator, the reaction force on the radiator, and the total radiated power arising from a harmonically excited, resilient, flat, circular radiator of radius a in an infinite baffle. The velocity profiles on the radiator are either Stenzel functions (1− (σ/a)) with σ the radial coordinate on the radiator, or linear combi...
The key parameters of Cerenkov Correlated Timing (CCT) detectors are discussed. Measurements of radiator geometry, optical properties of radiator and coupling materials, and photon detector timing performance are presented.
Silicosis and coal worker's pneumoconiosis are serious occupational respiratory diseases associated with the coal mining industry and the inhalation of respirable dusts containing crystalline silica. The purpose of this study (funded by the Mine Health and Safety Council of South Africa) was to evaluate the individual contributions of underground coal mining tasks to the respirable dust and res...
This paper presents an overview of observed distresses on low slope roofing systems collected for the Building Envelope Life Cycle Asset Management (BELCAM) project. The data include over 14,000 visible distresses from 600 roofs from seven different climatic regions across Canada. The distresses encountered for built up roofs, modified bituminous roofs and a limited number of single-ply roofing...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
بررسی ارتباط بین غلظت ذرات معلق در هوای داخل بیمارستان کودکان تهران و هوای آزاد اطراف آن در سال 1386
Background and Objectives: In recent years exposure to fine airborne particles has been identified as an important factor affecting human health. Epidemiological studies have showed that the aerosol laden air can be an agent for microorganisms’ dispersion. Ignoring internal sources, ambient air quality significantly affects indoor air quality. Since people spend most of their times in the indoo...
