in this article, rubber bumpers of double - wishbone suspension system have been modeled and analyzed. the objective of the present work is to predict the performance of these products during deformation, represent an optimum method to design, obtain stiffness characteristic curves and utilize the results in the automotive suspension dynamic analysis. these parts are nonlinear and exhibit large...

Dental crowding is the most common form of malocclusion. It more pronounced in mandible than maxilla and tends to increase with age. Depending on degree space deficiency age children prevalence dental can be as high 50%. Schwartz appliance lip bumper have been widely used an early treatment for increasing lower arch dimensions. The aim this review evaluate scientific research about efficacy com...

The European Commission is proposing legislation aimed at reducing the severity of injuries sustained by pedestrians in the event of an impact with the front-end of a motor vehicle. One aspect of this proposed legislation is reducing the pedestrian's leg injuries due to contact with the bumper and frontal surfaces of a vehicle, assessed using a 'pedestrian leg impact device,' or 'leg-form.' Thi...

Fundamental physics and numerous field studies have clearly shown a higher injury and fatality risk for occupants in smaller and lighter vehicles when colliding with a heavier, taller and a higher one. The consensus is that the significant parameters influencing compatibility in front-toside crashes are geometric interaction, vehicle stiffness, and vehicle mass. The objective of this research i...

Abstract This article proposed an innovative composite sandwich structure reinforced with trapezoidal latticed webs angles of 45°, 60° and 75°. Four specimens were conducted according to quasi-static compression methods investigate the compressive behavior novel structures. The experimental results indicated that specimen 45° showed most excellent energy absorption ability, which was about 2.5 ...

The present study was designed to investigate body position changes resulting from wearing a Rematee Bumper Belt (Rematee, Canada) during sleep. The majority of obstructive sleep apnea (OSA) patients will experience up to two times as many apneas and hypopneas while supine relative to lateral or prone body positions during sleep. It has been suggested that a positional therapy device could redu...

Buried bumper syndrome (BBS) is a rare complication developed after percutaneous endoscopic gastrostomy (PEG). We report a case of a 38-year-old male patient who sustained severe traumatic brain injury that was complicated with early BBS after PEG tube insertion. On admission, bedside PEG was performed, and 7 days later the patient developed signs of sepsis with rapid progression to septic shoc...
