To assess the working arrangements and effects on the health of medical emergency transport personnel, we conducted an electronic questionnaire survey among participants of the 16th National Ambulance-Crew Symposium in 2008. Answers were obtained from 58 participants (56 males, 2 females): 58 questionnaires were fully completed and suitable for analysis. Of the 58, 47 respondents were emergency...

Scatterplots are the most common way for statisticians, scientists, and the public to visually detect relationships between measured variables. At the same time, and despite widely publicized controversy, P-values remain the most commonly used measure to statistically justify relationships identified between variables. Here we measure the ability to detect statistically significant relationship...

The matter discovered at RHIC has shown a number of very surprising properties. It is extremely dense and has an initial energy density well above that expected for the phase transition from ordinary hadronic matter into quark gluon plasma. [1–4] The dense matter is very opaque to colored particles, such as quarks or gluons, traversing it. This gives rise to the striking jet quenching observed ...

A light cone efficiently transports, distributes, and concentrates the incoming radiation. I derive a formula for the spatial irradiance (or illuminance) distribution at the exit aperture of a tapered light pipe. The theory is demonstrated by Monte Carlo ray-tracing for lightpipes with light-emitting diodes at the input face. The analysis is based on the addition of the radiation patterns of th...

Paper discusses Advanced Aircraft configurational approaches, across the speed range, which are either enabled, or greatly enhanced, by clever Flow Control. Configurations considered include Channel Wings with circulation control for VTOL [but non-hovering] operation with high cruise speed, strut-braced CTOL transports with wing-tip engines and extensive [ÒnaturalÓ] laminar flow control, a midw...

OBJECTIVE The objective of this study was to report on a nine years of experience of providing medical support during house parties (raves) in the Netherlands, where they can be organized legally. DESIGN This was a prospective, observational study of self-referred patients from 1997 to 2005. During raves, first aid stations are staffed with specifically trained medical and paramedical personn...

introduction: hearing loss is one of the most disabling impairments. using a hearing aid as an attempt to improve the hearing problem can positively affect the quality of life for these people. this research was aimed to assess satisfaction of hearing impaired patients with their hearing aids regarding the employed technology and style.   materials and methods: this descriptive-analytic cross-s...
