The flow patterns of an exterior circular hood subject to the influence of various uniform cross drafts were experimentally studied in an apparatus consisting of hood-model/wind-tunnel assembly. A two-component laser Doppler anemometer was employed to measure the velocity field on the symmetry plane. The streamline patterns were obtained from the measured velocity data. The cross draft caused a...

Effects of flange size on the flow patterns of an exterior circular hood subject to the influence of various uniform cross drafts were studied in an apparatus consisting of hood-model/wind-tunnel assembly. The cross draft to suction velocity ratio covered the range from 0.056 to 0.792. The flange width to hood diameter ratio spanned from 1.2 to 3.0. The hood equipped without flange was also pro...

the issue of muhammad's illiteracy and the issues around it have been important debatable topics for a long time. this issue has both positive and negative news. opponents commonly attribute ommy to ommolghora that is the same mecca. however, advocates emphasize to prophet's illiteracy based on verse 48 (spider) and other qur'anic verses. there abundance of historical and anecdot...

Warren Weaver is the person generally credited with exciting interest in the possibilities of mechanical translation (MT) in the United States. (Earlier proposals came from a Russian, P. P. Smirnoff-Troyanski, and independently from a Frenchman, Artsouni.) His letter on the subject to some 200 of his colleagues in 1949 may be regarded as the beginning of this endeavor. The international confere...

In order to avoid the inherent aerodynamic difficulties of the conventional fume hood, an innovative design--the 'air curtain-isolated fume hood' is developed. The new hood applies a specially designed air curtain (which is generated by a narrow planar jet and a suction slot flow at low velocities) across the sash plane. The hood constructed for the study is full size and transparent for flow v...

BACKGROUND/AIMS Hood cap-assisted chromocolonoscopy using indigocarmine is expected to improve the detection rate of colorectal polyps, especially adenomatous polyps. Therefore, aim of the present study was to evaluate the usefulness of hood cap-assisted chromocolonoscopy in routine colonoscopic examinations. METHODS From January, 2013 through March, 2013, a total of 86 patients were enrolled...

Cooking stoves, both gas and electric, are one of the strongest and most common sources of ultrafine particles (UFP) in homes. UFP have been shown to be associated with adverse health effects such as DNA damage and respiratory and cardiovascular diseases. This study investigates the effectiveness of kitchen exhaust hoods in reducing indoor levels of UFP emitted from a gas stove and oven. Measur...
