More than 20 different leukocyte or tissue antigens can presently be recognized; they belong to one complex system (HL-A) which is, from the genetic point of view, very similar to the H-2 system in the mouse. Another independent system consisting of two antigens has also been well defined, the Group Five system. The methods of defining these antigens, their tissue distri bution, and complex rel...

mixed convection is a fundamentally significant heat transfer mechanism that occurs in selection industrial and technological applications. in this study, first the laminar mixed convection inside rectangular enclosure with moving wall and aspect ratio=10 is modeled and then the results are compared with other investigate. after showing varity of results, the investigation is continued with tur...

with the wind permanent flow in the cities, obtaining the minimal pollution in the environment is accessible. different policies have been considered for optimization of cities such as attachment and or reduction of building parts like air-traps, ceiling forms and so on. due to population growth in cities and the increasing need for resettlement these people in the cities, inevitably, to the hi...

introduction: for a velocity profile in turbulent flows, the flow conditions in the vicinity of the wall are described by logarithmic law of the wall. however, it has been extensively verified that the log-law does not apply in the outer region of the boundary layer. for example, in free surface flows, the law of the wall holds only for 20 percent of the flow depth from the wall. coles (1956) c...
