در این مقاله در چارچوب مدل انباشت بالستیک به شبیه سازی رشد لایه های نازک در حضور دو نوع ذره فعال (a) و ناخالصی(c) می پردازیم و نمای مقیاسی رشد و نمای مقیاسی زبری را به دست می آوریم و آن ها را با کلاس جهانی ارائه شده توسط کاردار-پاریزی-ژانگ (kpz) مقایسه می کنیم. نتایج به دست آمده وجود یک احتمال بحرانی را نشان می دهند، به گونه ای که به ازای مقادیر کوچکتر از ، مدل انباشت مورد نظر ما در کلاس جها...
The K-region trans-5,6-dihydrodiols formed in the metabolism of 12-methylbenz[a]anthracene (12-MBA) by liver microsomal preparations from untreated, phenobarbital-treated and 3-methylcholanthrene-treated male Sprague-Dawley rats were found by chiral stationary-phase h.p.l.c. (c.s.p.-h.p.l.c.) analyses to contain (5S,6S)/(5R,6R) enantiomer ratios of 93:7, 88:12 and 97:3 respectively. The absolut...
the first step in studying dust events is the estimation of dust emission from sources. in this study, the simulations of the vertical dust flux (vdf) over iran by the mba (marticorena, bergametti, and alfaro) and shao schemes are compared. the mba scheme is energy-based and derived on the basis of energy balance between the kinetic energy of saltating particles and binding energy of the surfac...
The multiple banded antigen (MBA) is a predicted virulence factor of Ureaplasma species. Antigenic variation of the MBA is a potential mechanism by which ureaplasmas avoid immune recognition and cause chronic infections of the upper genital tract of pregnant women. We tested whether the MBA is involved in the pathogenesis of intra-amniotic infection and chorioamnionitis by injecting virulent or...
Abstract − The pitch measuring accuracy for gear measuring instruments (GMIs) is evaluated by measuring a calibrated artifact. We proposed a novel artifact which called multiball artifact (MBA). The MBA is composed of the pitch balls assumed to gear teeth and the reference axis assumed to a center axis of gear. The MBA can be calibrated more accurate than a conventional pitch artifact. When the...
High throughput experiments can be used to spatially and temporally investigate the many factors that regulate cell differentiation. We have developed a micro-bioreactor array (MBA) that is fabricated using soft lithography and contains twelve independent micro-bioreactors perfused with culture medium. The MBA enables cultivation of cells that are either attached to substrates or encapsulated i...
Sequencing of mba gene fragments of reference strains of Ureaplasma urealyticum serovars 1, 3, 6, 14 and 8, in addition to 33 clinical U. urealyticum isolates is reported. A phylogenetic tree deduced from alignment of these sequences clearly demonstrates two major clusters (confidence limit 100%), which equate to the parvo and T960 biovars, and five types, which have been designated mba 1, 3, 6...
Maintaining student satisfaction and through it retaining students and having them recommend the program to others, is central to the success of any MBA program. This is especially important in distance learning programs because of their high dropout rates. The study shows the centrality of social norms outside the realm of the MBA program in determining three aspects of such satisfaction, name...
As we reported earlier, Muscat Bailey A (MBA) wine has very low proanthocyanidin (PA) content compared with Cabernet Sauvignon (CS) and Merlot wines. Whereas PA concentration in CS was maintained at the maximum level during maceration, that in MBA reached a maximum approximately four days after maceration and drastically decreased thereafter. In this study, the model wine extraction profiles of...
