background: nowadays, extensive technological advancements have made it possible to use nanopaints which show exciting properties. in ir iran excessive radon levels (up to 3700 bq m–3) have been reported in homes located in radon prone areas. over the past decades, concerns have been raised about the risk posed by resi- dential radon exposure. objective: this study aims at investigating the eff...

BACKGROUND/AIMS Pancreatic fistula is the most common complication after distal pancreatectomy. The aim of this study was to evaluate retrospectively the usefulness of a new surgical technique, the gastric wall-covering method, after distal pancreatectomy. METHODOLOGY The study group consisted of 53 patients who underwent distal pancreatectomy. The management of the stump of the remnant pancr...

We consider definably compact groups in an o-minimal expansion of a real closed field. It is known that to each such group G is associated a natural exact sequence 1→ G00 → G → G/G00 → 1 where G00 is the “infinitesimal subgroup” of G and G/G00 is a compact real Lie group. We show that given a connected open subset U of G/G00 there is a canonical isomorphism between the fundamental group of U an...

Algebraic explicit wall models covering the entire inner region of turbulent boundary layer are proposed to reduce computational effort for large eddy simulation wall-bounded flows. The formulas given in closed forms with either logarithmic- or power-function-based laws wall, allowing straightforward evaluation friction velocity on near grids independent their locations layer. performance is de...

OBJECTIVE We evaluated the effect of close contact between the stent and the graft on the induction of endothelial covering on the stent graft placed over an aneurysm. MATERIALS AND METHODS Saccular abdominal aortic aneurysms were made with Dacron patch in eight dogs. The stent graft consisted of an inner stent, a expanded polytetrafluoroethylene graft, and an outer stent. After sacrificing t...

Given a vector space V and a non-singular quadratic form Q on V , the orthogonal group O(Q) is the subgroup of GL(V ) that preserves Q. The special orthogonal group SO(Q) is given by O(Q) ∩ SL(V ). If Q is the standard inner product on R then SO(Q) is denoted SO(n). This is a connected, compact Lie group. For n > 2, the group is semi-simple. In the case that n is odd, SO(n) corresponds to the D...

In this article, we introduce the concept of co-covering which is the dual of covering concept. Then, we prove several theorems being similar to the theorems that have been de-veloped for the covering concept. For example, we provide the lifting criterion for co-coverings of a topological space X, which helps us to classify them by subgroups of the group of all homeomorphisms of X.

The wall gives a Saccharomyces cerevisiae cell its osmotic integrity; defines cell shape during budding growth, mating, sporulation, and pseudohypha formation; and presents adhesive glycoproteins to other yeast cells. The wall consists of β1,3- and β1,6-glucans, a small amount of chitin, and many different proteins that may bear N- and O-linked glycans and a glycolipid anchor. These components ...
