The most secure type of grasp of a frictionless woorkpiece is the form-closure grasp. However, task constraints may make achieving form-closure impossible or undesirable. In this case, one needs to employ a force-closure 1 grasp. In this paper, we study the subclass of force-closure grasps known as second-order stable grasps, which typically have a small number of contacts. We derive conditions...

Members of idempotents in (βN,+), especially those in the smallest ideal, have strong combinatorial properties. And the closure Γ of the set of idempotents has a simple combinatorial description. We investigate here the relationships among several subsets of βN that have simple combinatorial descriptions, as well as the semigroups they generate and their closures.

We use generalized Taylor formulae in order to give some simple constructions in the real closure of an ordered valued field. We deduce a new, simple quantifier elimination algorithm for real closed valued fields and some theorems about constructible subsets of real valuative affine space.

BACKGROUND Laparoscopic and rebotic surgery is widely practiced in modern medicine. The operative procedure is not complete until the port sites are closed with a fascial closure. Good fascial closure still represents problem, especially in difficult obese patients. This study reported simple technique is suitable in such cases. MATERIAL AND METHODS We herein describe a simple technique for f...

Background The use of negative-pressure wound therapy (NPWT) for Fournier gangrene management is well documented; however, it is difficult to fixate GranuFoam dressings and maintain an airtight seal over the perineum area. We developed a simple method to facilitate GranuFoam fixation and improve airtight sealing. Methods The Fournier's gangrene severity index (FGSI) score less than 9 was coll...

In this paper we will generalize  some of known results on the tight closure of an ideal to the tight closure of an ideal relative to a module .

Stress-relaxation is a well-established mechanism for laboratory skin stretching, with limited clinical application in conventional suturing techniques due to the inherent, concomitant induction of ischemia, necrosis and subsequent suture failure. Skin defects that cannot be primarily closed are a common difficulty during reconstructive surgery. The TopClosure tension-relief system (TRS) is a n...

Estimation of age at death is an essential part of reconstructing information from skeletal material. The aim of the investigation was to reconstruct the chronological age of an archaeological sample from Croatia using cranial skeletal remains as well as to make an evaluation of the methods used for age estimation. For this purpose, four age calculation methods were used: palatal suture closure...

The primary objective of this study was to determine which closure technique simple interrupted suture (SIS), simple continuous suture (SCS), interrupted double loop closure (IDLC) or continuous double loop closure (CDLC) results in stronger wound repair after midline laparotomy. Surgery was performed on 48 male rats. On the 5th postoperative day the rats were sacrificed and wound strength was ...

BACKGROUND AND OBJECTIVES Laparoscopic anastomotic methods are not commonly used because of the cumbersome laparoscopic intracorporeal sutures and tying involved. The barbed suture is one of the various devices developed to simplify the placement of intracorporeal sutures. However, barbed sutures are not commonly used during reconstruction after radical gastrectomy in cancer patients or for sin...
