Using cold working fastener holes is a simple life enhancement procedure that strengthens metallic components by retarding crack growth around a hole. In the present paper, the residual stress field that is induced by the hole expansion process is obtained based on different material models namely elastic perfect plastic, isotropic hardening and kinematic hardening using three-dimensional finit...
The aim of this paper is to introduce $(L,M)$-fuzzy closurestructure where $L$ and $M$ are strictly two-sided, commutativequantales. Firstly, we define $(L,M)$-fuzzy closure spaces and getsome relations between $(L,M)$-double fuzzy topological spaces and$(L,M)$-fuzzy closure spaces. Then, we introduce initial$(L,M)$-fuzzy closure structures and we prove that the category$(L,M)$-{bf FC} of $(L,M...
Background and study aims Complete closure of large mucosal defects after colorectal endoscopic submucosal dissection (C-ESD) is considered impossible in most cases because of the limited width of the open clip. We therefore invented a simple closure technique using clip-and-line, named "line-assisted complete closure (LACC)", and assessed its technical feasibility. Patients and methods Between...
This paper describes a new technique for the closure of oro-antral fistula/communication, in which both hard tissue (bone) and soft tissue closure is achieved. The sandwich technique utilizes a suitable bone grafting material sandwiched between two sheaths of Biogide (a resorbable membrane) for the hard tissue closure of oro-antral communication post traumatic exodontia. The bone grafting mater...
Background: Skin lesions and need for tissue evaluation, makes skin surgery an important part of treatment. Each excision is accompanied by skin repair. One of side effects of lesion excision is dog ear and cosmetic problems, particulary on face. Case Report: A middle age woman presented with an old leishmaniosis scar in her face. she asked how can we remove the lesion with minimal scar. In ...
Evidence is presented to support the recent suggestion that human neural tube closure is similar to that observed in mice, and comprises several regionally distinct closure sites rather than being a simple zipping up process. Seven subjects, each with more than one neural tube defect (NTD), are described. Comparative studies of the location of the lesions in relation to the closed parts of the ...
Our primary query is to Önd conditions under which the closure of a preorder on a topological space remains transitive. We study this problem for translation invariant preorders on topological groups. The results are fairly positive; we Önd that the closure of preorders and normal-orders remain as such in this context. The same is true for factor orders as well under quite general conditions. I...
