Background: Recently, the surgical methods are used in patients with anterior cruciate ligament rupture and have been associated with successful results. There are different results in the term of using of the surgical methods for anterior cruciate ligament that often is associated with some complications such as infection, static laxity, remaining the pain, need to recurrence surgery, and limi...

Expansion work recovery by two-phase ejector is known to be beneficial to vapor compression cycle performance. However, one of the biggest challenges with ejector vapor compression cycle is that the ejector cycle performance is sensitive to working condition changes which are common in real world applications. Different working conditions require different ejector geometries to achieve maximum ...

adjustable suture in strabismus surgery is a way to get accurate alignment of the eyes after operation. this technique is used in cooperative patients, being either adults or children. we report the result of this technique in 120 patients, 70 with esotropia and 50 exotropia. the amount of deviation was between 20 and 60 prismdiopters. the patients were mostly adults and teenagers. and the youn...

OBJECTIVE To evaluate the effects of laparoscopic adjustable gastric banding (LAGB) on esophageal dysfunction over the long term in a prospective study, based on a 12-year experience. BACKGROUND Esophageal motility disorders and dilatation after LAGB have been reported. However, only a few studies present long-term follow-up data. METHODS Between June 1998 and June 2009, all patients with i...

In this study, a novel virtual reality-based interactive method combined with the application of a graphical processing unit (GPU) is proposed for the semiautomatic segmentation of 3D magnetic resonance imaging (MRI) of the brain. The key point of our approach is to use haptic force feedback guidance for the selection of seed points in a bounded volume with similar intensity and gradient. For t...

performance optimization of chisel tine was proposed by using a chisel plow with adjustable rake angle. effective treatments consisted of soil moisture at 0.5, 0.7 and 0.9 of plastic limit (pl), three rake angle of 30, 40 and 50 degree and speeds of to 3, 5 and 7 km h-1. the measured parameters included draft, soil disturbance area, soil upheaving area, clod mean weight diameter (mwd), specific...

In order to fully explore the influence of different pressure methods on growth characteristics buckwheat, a test device with adjustable press force, and easy replace wheel was designed. Using dry matter quality buckwheat roots, stems, leaves at seedling stage, plant height, number main stem nodes, branches, grain per plant, weight yield as evaluation indexes, single factor force carried out, t...
