We conducted this study to define the value of fiberoptic bronchoscopy (FOB) in the evaluation of chest radiographic abnormalities and to provide guidelines for fiberoptic bronchoscopy on the basis of chest radiographic appearances. Fiberoptic bronchoscopy without fluoroscopy was carried out in 530 patients, 455 male and 75 female, aged 19 to 85 years, during a 1-year period at Chest Department...
Regression rate is one of the most important parameters in designing of hybrid rocket motors which is dependant into many factors like oxidant mass flux, grain length and chamber pressure. In this article, the effects of grain length and chamber pressure are considered besides of oxidant mass flux using HTPB-N2O lab-scale hybrid motor. Because of dependency of regression rate into three factors...
S-layer proteins of Deinococcus radiodurans are the best self-assemble systems among other proteins that have an essential role in the fabrication of nanowires. Therefore, the purification of these proteins is necessary. The purpose of this research was to optimize the purification of s-layer protein from D. radiodurans with the response surface method. The three factors of SDS concentration, i...
The optimal material processing in steel industry is difficult because of the multi-constituent and multiphase character of the commercial steels, variety of the possible processing paths, and plant specific equipment characteristics. This paper shows implementation of the genetic programming approach for crack presence modeling after rolling. The data (110 samples covering 7 different steel gr...
Instruments for optical fiber measurements, such as the Fiber Quality Analyzer (FQA), are widely used to measure various properties of pulp samples. For the evaluation of market pulps, the pulp properties of interest are fiber length, coarseness, and fines content. Fiber length and coarseness are often used to determine which pulps are suitable for producing particular products. The objectives ...
