Plasma knife (PK) assisted UPPP is a modification of the procedure original described by Fujita for snoring. Plasma knife is used for tonsillectomy, hemostasis and to reduce scar contracture lowering incidence of dehiscence (1%) as a result of the reduced thermal injury. Cold knife resection of uvula is limited to the anterior mucosa and any submucosal; preserving the muscularis uvulae and post...

In this paper, a blind restoration method is presented to remove the blur in remote sensing images. An alternating minimization (AM) framework is employed to simultaneously recover the image and the point spread function (PSF), and an adaptive-norm prior is used to apply different constraints to smooth regions and edges. Moreover, with the use of the knife-edge features in remote sensing images...

acoustic neuromas (an) are schwann cell-derived tumors that commonly arise from the vestibular portion of the eighth cranial nerve also known as vestibular schwannoma(vs) causes unilateral hearing loss, tinnitus, vertigo and unsteadiness. in many cases, the tumor size may remain unchanged for many years following diagnosis, which is typically made by mri. in the majority of cases the tumor is s...

Submucosal tunnel endoscopic resection (STER) is a standardized technique for the enucleation of small submucosal midgut tumors [1,2]. For lesions smaller than 2 cm, the suggested management is long-term surveillance [2]. However, en bloc ablation is a possibility in order to obtain definite histology and avoid lifelong follow up [2]. Furthermore, in bariatric surgery, the detection and resecti...

Machined workpieces must satisfy quality standards such as avoid the presence of burrs in edge finishing to reduce production costs and time. In this work we consider three types burr that are determined by distribution shape on a microscopic scale: knife-type (without imperfections), saw-type (presence small splinters could be accepted) burr-breakage (substantial deformation produces unusable ...

A 10-year-old girl suffering from a penetrating orbital stab wound with a knife on the inner canthus of her right eye is reported. Clinical examination of the patient displayed no signs of globe perforation or neurological deficits. The knife was removed slowly with careful and controlled motions. At the last visit three months after the surgery, visual acuity was 20/20, anterior and posterior ...

The paper introduces virtual manufacturing application in the Fields Cultivate Machines and mainly discusses the model-building of rotary-cultivate part, physical model and mathematical model included. With the model, the rotary knife is optimized, the force on the bend part is decreased, and therefore, the service life is prolonged. At the same time, with dynamic analysis software Adams, the m...

Air knives with very different nominal values are used for various purposes in the industry. The uses of air include painting and coating stages automobile semi-finished products, as well many related to food production. One important sectors among these is continuous hot-dip galvanizing process, which a technique steel In addition, chemical process on paper thin layer another research topic. m...

In microtomy, faults of the cutting edge are an obvious and avoidable source of artifact. The purpose of this communication is to describe a simple apparatus for viewing and marking the cutting edge of the glass knives which are used in see-tioning for electron microscopy (1, 2). The apparatus consists of a monocular microscope with base, arm, body tube, coarse and fine adjustments, an annular ...

Dracontiasis is an infestation of man by the guineaworm, Dracunculus medinensis; a similar infestation also occurs in animals,' and a related species, Dracunculus insignis, is known to infect racoons, mink, and dogs.2 The disease, at the present time, has a wide distribution throughout tropical and subtropical regions ofthe world. The rate of human infestation varies with the possibility of the...
