We reveal an outstanding potential of water as an inexpensive, abundant and bio-friendly high-refractive-index material for creating tunable all-dielectric photonic structures and metamaterials. Specifically, we demonstrate thermal, mechanical and gravitational tunability of magnetic and electric resonances in a metamaterial consisting of periodically positioned water-filled reservoirs. The pro...

It has been suggested that exposure to heavy school backpacks is a relatively recent phenomenon. Factors such as reduced use of student lockers secondary to security concerns, an increased use of laptop computers, and increased carrying of non-educational loads such as musical instruments and sports equipment have potentially increased student exposure to heavy load carriage. It is therefore pl...

The International Relations Committee of the Association of Anaesthetists of Great Britain and Ireland was established over 30 years ago to assist anaesthetists working in developing countries. The committee has attempted to make an impact through distribution of educational materials, supporting training courses and investing in a number of small equipment projects. In 2005, the Overseas Anaes...

Over the past 30 years clinicians have sought to find approaches to care that will solve the thorny issue of pressure ulcer damage. Huge amounts of effort and money have been put into developing care frameworks, educational packages and high-tech pressure-relieving equipment. These efforts should be applauded and yet provision of care free from the fear of pressure ulcer development is still no...

The energy use patterns of electrical appliances are more difficult to predict than for heating, ventilation, and air-conditioning (HVAC) lighting, as: (1) there large varieties equipment (e.g., appliances, vending machines, etc.) in buildings each serves a different function; thus, their consumption predict; (2) scattered across buildings, most not permanently fixed location, they consume much...

Home mechanical ventilation requires equipment, consisting of a generator of pressure, a tubing and an interface to deliver air to the patient. Instructions for equipment maintenance are generally not based on scientific evidence. Studies however have reported that tubing and masks used at home are the most commonly found as very dirty and contaminated. Dirtiness and contamination of equipment ...
