base deficit is a non-respiratory indicator of acid base status. aim of this study is to assess relationship between the base deficit value in immediate post operative period of cabg and valvular heart disease with cardiopulmonary and in hospital outcome of patient. a total of 136 consecutive with cabg and valvular heart disease scheduled in study. 20 variables were determined during the pre-in...

The physical adsorption of hydrogen sulfide and carbon dioxide gases on the zigzag (5,0) carbon nanotubes doped with nitrogen was investigated through the application of B3LYP/6-31G* at the level of theory on Gaussian 03 software. A variety of stable and high abundance structures of nitrogen doped carbon nanotubes were considered in order to study the interaction between the mentioned gases in ...

The lubricating oil consumption (LOC) in internal combustion engines contributes to emission and deteriorates the performance of aftertreatment. In this work, an optical engine with a 2D Laser-induced fluorescence (2D-LIF) system was used study operating conditions critical real driving emissions. Additionally, numerical models were analyze ring dynamics, flow gas flow. It found that intake pre...

the objective of this study was to find a relationship between blood gas parameters and thyroid hormoneactivity with ascites syndrome in broiler chickens exposed to cold temperature and receiving a high qualitydiet. one hundred and sixty one-day-old broiler chicks were randomly divided in two equal groups. toincrease the incidence of ascites, chicks of group 1 were fed ad libitum with a higher ...

The acute and chronic action of the oxidant gases ozone, nitrogen dioxide and oxygen on the morphological appearance of cells of the alveolar and bronchiolar epithelium is reviewed. Type I cells of the alveolar and ciliated cells of the bronchiolar epithelium appear to be sensitive targets for the oxidant gases. The degree of damage is influenced by age, nutritional status and the development o...

Increases in the number of winter visitors to Yellowstone National Park during the past decade have raised concerns over the environmental impacts of snowmobiling in the park. During the 1998-99 season, more than 62,000 snowmobile and 1300 snow coach trips entered the park. Using the University of Denver's vehicle exhaust remote-sensing equipment, 1385 measurements of carbon monoxide (CO) and h...

the objective of this study was to determine the effects of diets having different fermentability on blood gases, blood metabolites and ruminal fermentation parameters in holstein dairy cows. four multiparous holstein dairy cows (665 ± 25 kg bw, 170 ± 7.0 dim and 15±1.5 kg of milk yield), fitted with rumen cannulae, were used in a 4×4 latin square design with 28-d periods. corn starch and sucro...

The HP scrubber is an equipment used to separate liquid from gas in the oil and industry. low level vessel one of abnormal conditions scrubber, a blowby event will happen because level. So, controller indicator required prevent system damage workplace accidents. alarm response time calculated order avoid accident. To determine for dynamic process simulation method can be using Aspen HYSYS versi...
