Gaseous elemental mercury (GEM) and reactive gaseous mercury (RGM) were measured during an eight month circumnavigation to obtain knowledge of their worldwide distributions in the marine boundary layer (MBL). Background GEM concentrations were found to be 1.32 ± 0.2 ng/m(3) (summer) and 2.62 ± 0.4 ng/m(3) (spring) in the northern hemisphere and 1.27 ± 0.2 ng/m(3) (spring and summer) in the sout...

Introduction The province of Ontario, Canada has approximately thirteen million residents spread over approximately one million square kilometers. Ontario ensures a high level of medical care for all residents partly through an advanced medical transport capability. The not-forprofit company Ornge provides these transport services primarily through air-ambulance services, although it also has s...

Abstract We present “Gesture of In-Kindness,” an interactive art project comprising four household devices that respond in-kind to observers’ gestures. These devices include a fan that blows air at the observer only when the observer is actively blowing his or ...

[1] A CGCM is used to study the relative roles played by local air-sea interaction and remote ENSO effects on the tropical Atlantic interannual variability. A regional coupling strategy allows full air-sea coupling only over the Atlantic Ocean north of 30!S. Two experiments were conducted, respectively with either climatological or real time boundary conditions prescribed over the uncoupled por...

In the month following the terrorist attacks of September 11, domestic air travel in the United States dropped more than 30% relative to the same period the previous year. More than six months later, revenue passenger miles remain more than 10% below what they were last Spring (Air Transport Association, March 6, 2002). Such reluctance to fly has obviously contributed to the recent recession in...

abstract background: and soils with which it comes in contact. there is dual exposure from radon in water i.e. due toinhalation of the radon released from the water into the ambient air and through ingestion whenwater is used for drinking. as radon contaminated water adversely affects the health, it istherefore fundamental from health and hygiene point of view to measure radium concentrationand...
