This study aimed to investigate the relative performance of two models (negative binomial (NB) model and two-component finite mixture of negative binomial models (FMNB-2)) in terms of developing crash modification factors (CMFs). Crash data on rural multilane divided highways in California and Texas were modeled with the two models, and crash modification functions (CMFunctions) were derived. T...

Latex products have long been recognized as a cause of latex protein allergy. The increased usage of latex gloves, with the consequent increased occurrence of latex allergies appears to have escalated with increasing awareness of the transmission of HIV-AIDS and other infections. The use of condoms as a means to prevent the transmission of STD's (sexually transmitted diseases) and HIV-AIDS has ...

The controversy over the use of nuclear energy fundamentally comes down to three main considerations: its safety of use, ability of nuclear energy generation to reduce greenhouse gas emissions and finally its long term sustainability. The paper addressed the problem of safety in the industrial and medical use of nuclear energy, as it is affected by the design and construction of light and heavy...

This paper provides an overview of the published literature regarding magnetic resonance imaging (MRI) safety. It gives basic information about the electromagnetic fields that are generated during the MRI diagnostic procedure, followed by a description of the biological effects of those fields on humans. It concludes with a discussion of the safety issues related to MRI use in clinical practice...

Biomimetic materials are designed to stimulate specific cellular responses at the molecular level. To improve the soundness of in vitro testing of the biological impact of new materials, appropriate cell systems and technologies must be standardized also taking regulatory issues into consideration. In this study, the biological and molecular effects of different scaffolds on three neural system...

objectives: the objective of this study is to evaluate the safety climate as an important part of macroergonomics domains and to determine the importance of each safety climate factor in an iranian company. methods: for data gathering, the researchers used macroergonomic organizational questionnaire survey (moqs) method. for conducting this method we applied safety climate questionnaire which h...

The 7 Amendment to the EU Cosmetics Directive has made developing non-animal approaches to assure the safety of consumer products a key business need to support future innovation. A substantial research programme was initiated by Unilever in 2004, aimed at critically evaluating the feasibility of a proposed new conceptual approach. The key aspects of this approach are: 1. Developing new risk as...

The aim of the study was to optimize the biological safety scheme of spinal image-guided radiotherapy (IGRT) by determining the expression of caspase-3 in spinal cord neurons after IGRT. Thirty-six adult male beagles were assigned according to a random number table and subjected to IGRT to the 7th-12th canine thoracic vertebral bodies under a total dose of 80 Gy over 5 weeks. An immunohistochem...

Opportunity for Nanotechnology: The innovative field of nanotechnology is most likely to gain societal acceptance if environmental and human health considerations are thoroughly investigated and those results are used to optimize safety and performance together to produce effective and non-toxic profitable technologies. Industrial and scientific communities must work together to integrate toxic...
