Low radiation intensity heat transfer from methane blue flame has turned into a challenge in industry. The addition of soot into the flame can enhance the radiation. However, the effect of adding soot on chain reaction of methane combustion and NO & CO emissions has not been assessed. Furthermore, one of the most important factors to be considered is the size of the fine particles. Therefore, t...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
the aim of this study was to evaluate the role of fine needle aspiration cytology in the diagnosis of abdominal and retroperitoneal masses in children on this study. in 53 cases of childhood abdominal and retroperitoneal masses within a 4 year period (1998- 2001) preoperative fine needle aspiration was done under the guide of ct scan. 2 pathologists reviewed fine needle aspiration smears. in al...
the increasing use of nitrogen fertilizers due to high dynamics of nitrate in the soil would be a serious threat to groundwater, and therefore, to thuman health. this study is aimed to investigate the disperdivity values of nitrate in the coarse, medium and fine sandy soils in the short travel distance of 20, 40 and 80 cm in vitro using the hydrus-1d model. for this purpose, pure potassium nitr...
In this article, we discuss the Fine computability and the effective Fine convergence for functions on [0, 1) with respect to the Fine metric as the beginning of the effective Walsh-Fourier analysis. First we treat classically the Fine continuity and the Fine convergence. Next, we prove that Fine computability does not depend on the choice of an effective separating set. Subsequently, we propos...
Fine-needle aspiration biopsy for the diagnosis of breast lesions has been used for more than six decades and has been established as an effective procedure in Europe for many years. In order to evaluate the accuracy of fine-needle aspiration with histopathologic confirmation, a retrospective study was performed in Iranian Center for Breast Cancer, using a computer database over one year period...
this paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. a laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
