background: the present study was designed to ascertain serial changes on distal radius radiographic parameters attributable to aging.       methods: in this prospective study, the sample consisted of 120 healthy individuals who were divided into four age groups each containing 15 males and 15 females. in the two below-20-year-old groups, only ulnar variance could be investigated. wrist radiogr...

Active steering systems can help the driver to master critical driving situations, for example aquaplaning and -split braking. In these situations it is likely that the tires reach their performance limits, where nonlinear effects like saturation play an important role. Tires are the part in vehicle dynamics afflicted with the highest degree of nonlinearity – due to saturation – and uncertainty...

Crumb rubber is a material produced by shredding and commutating used tires. Waste tire dumping, disposal of these materials or burning these tires cause serious health and environmental problems. On the other side the traffic intensity also increasing day by day and thus bearing capacities also increased the long term goal of the work is to find a means to dispose of the crumb rubber in concre...

We evaluated injuries to Spartina alterniflora by debris items common to North Carolina coastal waters as a function of debris type (wire blue crab pots, vehicle tires, and anthropogenic wood) and deployment duration, and monitored S. alterniflora recovery following debris removal. Injuries sustained by S. alterniflora and subsequent recovery, varied considerably between debris types. Differenc...

High-content waste-rubber-modified asphalt (HRMA) has high viscosity and poor storage stability. HRMA not only improves the properties of road asphalt, but also reduces environmental pollution caused by waste tires. Enhancing molecular interaction rubber is key to making full use HRMA. In this paper, aromatic oil was used as activator for rubber. The mechanism between investigated. radial distr...

?? A steering arm, made from a three piece weldment was creating problems in manufacturing. It was converted to a one piece impression die hot forging at a 13% reduction in weight and reduced manufacturing cost. ?? A cast hub for a large power shovel in a coal field failed, causing an estimated downtime of four to six weeks at a cost of $4000 per hour. The hub was slightly redesigned as an open...

A state-wide survey of tire-breeding mosquitoes in Alabama was conducted in 2004 and 2005. Tire sites in all 67 counties in the state of Alabama were sampled for mosquito larvae. A total of 13,022 mosquito larvae, representing 12 species in 7 genera, was collected. The most frequently collected species were Aedes albopictus (70.4%), Culex territans (8.0%), and Ochlerotatus triseriatus (7.1%). T...

This paper studies the addition of fibers from end-of-life tires to commercial mortar mixtures. Two different types of mortar, one lime-plastic and other cement-fluid, are mixed with different percentage of fibers ranging from 0% to 1%. The changes in bulk density, consistency, compressive and flexural strength, dynamic Young modulus and water absorption are studied. According to the results, c...
