مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...

‎‎‎in this paper‎, ‎the‎ notion of injectivity with respect to order dense embeddings in ‎‎the category of $s$-posets‎, ‎posets with a monotone action of a‎ pomonoid $s$ on them‎, ‎is studied‎. ‎we give a criterion‎, ‎like the baer condition for injectivity of modules‎, ‎or skornjakov criterion for injectivity of $s$-sets‎, ‎for the order dense injectivity‎. ‎also‎, ‎we consider such injectivit...

An investigation isundertaken to study the transmission of the electromagnetic waves through inhomogeneous over-dense plasma. The transmission is due to the excitation of the surface modes of plasma or plasmons. The construction of the plasma is in such a way that the charge density of the plasma linearly increases and passes through its critical value and then linearly decreases. The dissipati...

Forest trees demonstrate different distribution patterns, depend on their living condition (Such as pest infestations). Forest density and epidemic pest concentration are hypothetically among the most influential factors. The current study was carried out on distribution pattern of the orchard ermine (Yponomeuta padella) infested hawthorn trees (Crataegus monogyna) in Bazoft river watershed in ...

to determine the effect of bilateral uterine artery ligation (bual) on mast cell (mc) distribution, 24 mature female rabbits were studied. the rabbits were ovariohysterectomized on day 23, 43 or 63 following bual. histological sections were stained with toluidine blue to determine the mc distribution. in rabbits that had undergone bual, mcs were present extensively in the helium of the treated ...

Abstract Decadal changes in land use/land cover for Balachaur watershed in Nawanshahar district, Punjab, India were studied using black and white aerial photographs for March 1984 on approximately 1:20,000 scale and multidate geocoded false colour composites (FCC) of IRS-1D LISS-III on 1:50,000 scale for March 2002, September 2002, and May 2003 and interpreted visually to prepare land use/land...

We consider drawings of graphs that contain dense subgraphs. We introduce intersection-link representations for such graphs, in which each vertex u is represented by a geometric object R(u) and each edge (u, v) is represented by the intersection between R(u) and R(v), if it belongs to a dense subgraph, or by a curve connecting the boundaries ofR(u) andR(v), otherwise. We study a notion of plana...
