In many respects international sportsmen are trendsetters for the behaviour of recreational sportsmen. For this reason the attitude of international hockey players towards mouth protectors was studied. The possession and use of mouth protectors vary markedly between different countries. The incidence of dental-facial traumas among international field hockey players is high; 54% had sustained in...

Farmers experience higher rates of noise-induced hearing loss (NIHL) than workers in most other industries. We developed a model of farmers' use of hearing protection, and tested it with a random sample (n = 532) of farmers from the upper Midwest. Barriers to using hearing protection (e.g., difficulty communicating; OR = .44, p < .003) were negatively related to use. Greater access/availability...

Over the past decade, microRNAs (miRNAs) have emerged as essential posttranscriptional regulators of gene expression. Though a great deal has been discovered about miRNA genomics, biogenesis, mechanisms, and functions, the challenge of attributing phenotypes of altered miRNA expression to specific targets still remains. Here, we apply the existing target protector concept of blocking miRNA acti...

Military training creates unique noise hazards including high impulse noise content. The need for hearing protection needs to be considered alongside the need for effective voice communication. This requires a hearing protector with high impulse protection that minimally impedes low intensity voice communication. These level dependant devices are called non-linear hearing protectors. A range of...

In Zimbabwe, over 25% of adults are HIV positive [1]. To curtail the epidemic, the government started promoting condom use, especially in non-marital relationships. Since 1996, Population Services International (PSI) has implemented a USAID/British Department for International Development-funded condom social marketing program that distributes subsidized Protector Plus condoms, and promotes the...

Surge protective device is a part of internal lightning protection and it crucially to divert the certain amount of surges to the ground before the protected load able to handle. Therefore, this paper studying the enhancement of SPD through the effect of adding a filter in hybrid surge protection circuit using simulation modeling. Ordinarily, filter is used as in eliminating noises in certain a...
