In this study, mechanical tests were performed on a Chinese car bumper of the Chery model, which was chosen for examination due to its widespread use in Iraqi streets. It also compared best specimens obtained these study stages. Glass fiber mats and nanoparticles have been mixed with unsaturated polyester resin (UPE) two first stage, fibers volume fraction 14% properties calculated. second diff...

Although considered as a safe method to provide long-term nutritional support, percutaneous endoscopic gastrostomy (PEG) may be complicated by a buried bumper syndrome (BBS), a life-threatening condition. Removal of the PEG tube with its buried bumper and reinsertion of a new PEG tube is often necessary. Since its description in 1988, less than 50 cases of BBS managed by external extraction of ...

Worldwide, the pace of development in pedestrian countermeasures is increasing rapidly. To better understand the state of the art in bumper design for pedestrian impact, a survey of literature and patents has been performed. Two general approaches to reducing the severity of pedestrian lower limb impacts were identified: (a) Provide cushioning and support of the lower limb with a bumper and a n...

Feeding via percutaneous endoscopic gastrostomy (PEG) is the preferred form of alimentation when oral feeding is impossible. Although it is a relatively safe method, some complications may occur. One uncommon PEG complication is buried bumper syndrome. In this paper we report a case of buried bumper syndrome, successfully managed with PEG tube repositioning.

US and European pedestrian crash cases were analyzed to determine frequency of injury by body region and by the vehicle component identified as the injury source. US pedestrian data was drawn from the Pedestrian Crash Data Study (PCDS). European pedestrian data was drawn from the German In-Depth Accident Study (GIDAS). Results were analyzed in terms of both serious injury (AIS 3+) and disabling...

but serious complication of percutaneous endoscopic gastrostomy (PEG). Although a variety of nonoperative techniques have been used to manage the syndrome [1, 2, 3], surgical intervention is necessary to rectify the problem in most cases [4]. We report on an endoscopic method for treating the buried bumper syndrome, using a Savary dilator over a guide wire. Between January 2001 and May 2005, 12...

The pressures from the lower lip on the lower incisors were measured at the midline between the central incisors and between the left lateral incisor and canine. The measurements were made with the lip at rest and during swallowing of water in 24 boys and 40 girls aged 9-15 years. The children were divided into four groups, two treated with a lip bumper with and without an oral shield, and two ...

AIM "Buried bumper" is a complication of percutaneous gastrostomy related to the internal flange getting buried into the wall of the stomach. The aim of this study is to evaluate the management of this complication. METHODS The surgical and interventional radiology database in our hospital from August 1999 to May 2011 was analyzed. There were 2,007 patients who underwent percutaneous gastrost...

At present, aluminum bumper has been used in the field of passenger cars. In order to provide technical reference for alloy be developed, and better develop bumper, this project analyzes material process an existing from perspective mechanical properties, composition, connection method between each component. Through crushing, static pressure, collision test simulation technology, performance b...
