Case 3 is a rare congenital abnormality of the inner ear which usually presents as recurrent meningitis. This abnormality is now well documented.4 It should be suspected as a cause of recurrent meningitis in a child who has a sensorineural deafness. The presence of fluid behind the tympanic membrane should make one suspicious and the diagnosis can be confirmed by tomograms of the inner ear. The...
considering different fertility traits 411 cows from 73 farms used for economic analyses. from these, 202 lactating cows were selected for evaluating the fertility status. pre-tested data sheets were used to record the socioeconomic status of the farms including their assets, cost and return and productive and reproductive performance of the dairy cows. targets were set considering the situatio...
background : computer users are exposed to work related neck disorders due to repetitive movement and static posture for prolonged period. viewing document and typing simultaneously are one of the contributing factors for neck disorders. methods : this preliminary study was conducted to evaluate the effects of the document holder on the postural neck muscles activity among computer users. nine ...
This paper presents the application of iSight for optimal tip design of complex tool holder spindle. The complex tool holder is used for holding a (milling/drilling) tool of a machine tool. The engineering problem of complex tool holder results from the twisting of spindle of tool holder. This leads to the vibration of tool holder which makes the tool holder malfunction. This engineering proble...
dotracheal tube and are composed of inspiratory and expiratory corrugated limbs. The two breathing tubes carry respiratory gases with volatile anesthetics to and from patients during general anesthesia. Although longer corrugated breathing tubes allow the anesthesia machine to be located farther from the patients, they are so long and flexible that they tend to hang down below the operating tab...
A system was developed and tested to provide a deeper understanding of the fission gas release kinetics from nuclear fuel during thermal transients. Pressure, temperature, spectral data, optical images were simultaneously collected resistive sample heating, all released gases in liquid nitrogen-cooled charcoal traps. Standup testing performed with high-burnup segment rod section an average loca...
The understanding of solid-gas interactions has been greatly advanced over the past decade on account of the availability of high-resolution transmission electron microscopes (TEMs) equipped with differentially pumped environmental cells. The operational pressures in these differentially pumped environmental TEM (DP-ETEM) instruments are generally limited up to 20 mbar. Yet, many industrial cat...
توالی کربناته-دولومیتی بخش بالایی سازند دالان با میان لایه های تبخیری و به سن پرمین پسین، یکی از مهم ترین مخازن گازی در نواحی زاگرس چین خورده و بخش های وسیعی از خلیج فارس محسوب می شود. در بررسی مقاطع نازک در دو چاه از میادین سلمان و لاوان سیزده میکروفاسیس و دو زیرفاسیس شناسایی گردید که در چهار کمربند رخساره ای پهنه جزرومدی، لاگون، سد و دریای باز در بخش داخلی تا ابتدای بخش میانی یک رمپ هموکلین...
