background: as adolescent tobacco smoking has become a widespread problem in developing countries, it is time to understand the cognitive determinants of adolescents' decisions to engage in tobacco smoking. this study aimed to investigate the predicting factors associated with tobacco smoking among male adolescents based on prototype willingness model (pwm) as a theoretical framework. methods :...

Abstract The limited availability of real-time wave data is needed for shipping safety and planning coastal areas. This monitoring system including the height direction gained to be used as a consideration in making decisions related management. study aims design create prototype simple mini-wave gauge test performance on laboratory scale. sensors this were ADXL335 vibration sensor detect movem...

in this study, a laboratory scale continuous plug flow fluidized bed dryer was designed and constructed. a backward-curved centrifugal fan with a 4 kw electromotor was selected based on the maximum pressure drop in the minimum fluidization state and the ability to produce the velocity required for fluidization of the most granular agricultural materials. the fluidization chamber was a rectangul...

There are currently no appropriate methods for measuring dermal exposure to volatile agents. To address this we have produced a prototype Institute of Occupational Medicine (IOM) dermal sampler consisting of an adsorbent sandwiched between a permeable membrane and an impervious backing. The concentration of solvent on the membrane surface may be estimated from the mass collected on the adsorben...
