road accident severity may be influenced by a number of various systematic causal factors. the weather and road accidents have a close relationship with each other and a number of methods have been proposed for measuring the risk of a road accident with rainy, foggy, and snowy weather and high winds. recent studies indicate that road collision rates increase during precipitation. the weather wa...

Frontage roads are most frequently used in rural and urban environments along freeway and full-controlled principal arterial corridors. Their primary function is to distribute and collect traffic between local streets and interchanges. They have been the primary design solution for providing access along Texas rural freeways and full-controlled principal arterials. With the growing public deman...

The United States general aviation fleet is aging with aircraft manufactured 35–39 years ago representing the most prevalent group. Since older aircraft are more prone to airframe corrosion, fatigue, and brittle electrical wiring, the present study was undertaken to determine whether malfunction-related accidents for general aviation aircraft manufactured between 1970 and 1984 were elevated rel...

Aggregation of Cu, Zn superoxide dismutase (SOD1) is often found in amyotrophic lateral sclerosis patients. The fibrillar aggregates formed by wild type and various disease-associated mutants have recently been found to have distinct cores and morphologies. Previous computational and experimental studies of wild-type SOD1 suggest that the apo-monomer, highly aggregation prone, displays substant...

By T. C. Willett. {Tavistock, 42s.) American research findings suggest that accident-prone drivers as a group from accident-free drivers in being significantly more often aggressive, extro^ sexually promiscuous, having a police record, and being reared in a conflict-ri1 home. These characteristics are so like those alleged to be associated with delinque'1'' that Dr. Willett was led to question ...

background: there is a high prevalence of  occupational injuries due to accidents in construction industries which affect human health. therefore, the exploration and analysis of contributing factors of such accidents can lead to their prevention and the reduction of their consequences. this study was conducted with the aim to identify factors related to occupational injuries and the severity o...

In the period 1987 to 1989 there were about 5,000 cases of fatal and injury-sustained road traffic accidents, of which 2.3 to 3.0% were alcohol-related (Blood alcohol levels greater than the legal limit of 80 mg % ethanol). The offenders of alcohol-related accidents are mostly Chinese (greater than 79%), predominantly of the male gender (greater than 98%), and more often than not in the 30 to 4...

Accidental mechanical asphyxia is an unusual cause of death. In reviewing 73 cases occurring during a 10-year-period in Sweden, young boys and elderly women seemed to be most prone to this type of fatality. A striking number of victims had deliberately put a noose-like structure around the neck, and yet another group became entangled in some part of their clothing. Thoracic immobilization was s...

The reliable identification of beta-aggregating stretches in protein sequences is essential for the development of therapeutic agents for Alzheimer's and Parkinson's diseases, as well as other pathological conditions associated with protein deposition. Here, a model based on physicochemical properties and computational design of beta-aggregating peptide sequences is shown to be able to predict ...

OBJECTIVE The mechanisms promoting the focal formation of rupture-prone coronary plaques in vivo remain incompletely understood. This study tested the hypothesis that coronary regions exposed to low endothelial shear stress (ESS) favor subsequent development of collagen-poor, thin-capped plaques. APPROACH AND RESULTS Coronary angiography and 3-vessel intravascular ultrasound were serially per...
