background:  the purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   methods:  this is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. the average time between implantation and removal was 23 month...

This paper presents an innovative digital method to analyse agricultural tire profiles based on pictures. From this method, we can conclude that the deformation is caused by changes in vertical load and inflation pressure. The first stage 3D-scanning; cross-section created from obtained picture of tested tire. cross-section, deflection be determined. Then, horizontal - operation allows determin...

In August, 1985 an infestation of. Aedes olbopictus (Skuse) was discovered in Harris County, Texas. It was the first breeding population reported in the continental USA (Sprenger and Wuithiranyagool 1986). Since 1985, Ae. albopictus has spread to 17 eastern states (Centers for Disease Control 1987) and eggs have the ability to diapause and overwinter in northern latitudes (G. B. Craig, personal...

Often when vehicles interact with roadside hardware like guardrails, bridge rails and curbs, the interaction between the roadside hardware and the tire causes the tire to lose its air seal and "blow-out". Once the seal between the rim and rubber tire is lost, the tire deflates. The behavior of the deflated tire is much different than the behavior of an inflated tire such that when this behavior...

The natural frequencies and mode shapes of pneumatic tires are predicted using a geometrically accurate, three-dimensional finite element modeling. Tire rubber materials and cord layers are represented independently using “shell element” available in COSMOS. The effects of some physical parameters such as the inflation pressure tread pattern, thickness of belts and ply angles to the natural ...

Discarded vehicle tire casings are an important artificial habitat for the developmental stages of numerous vector mosquitoes. Discarded vehicle tires degrade under ultraviolet light and leach numerous soluble metals (e.g., barium, cadmium, zinc) and organic substances (e.g., benzothiazole and its derivatives [BZTs], polyaromatic hydrocarbons [PAHs]) that could affect mosquito larvae that inhab...
