    air quality
  • Air quality is defined as a measure of the condition of air relative to the requirements of one or more biotic species and or to any human need or purpose.
  • The extent to which air is free from contaminants, conventionally taken to be the respiratory irritants nitrogen dioxide and sulfur dioxide.
  • The degree to which the ambient air is pollution-free, assessed by measuring a number of indicators of pollution
  • A measure of the health-related and visual characteristics of the air, often derived from quantitative measurements of the concentrations of contaminating or injurious substances.

Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., Sick Building Syndrome). This instrument is ideal for monitoring indoor air quality in crowded public spaces with potentially high levels of CO2 (carbon dioxide) such as offices, factories, classrooms, hospitals and hotels. The same measurement parameters can also be used to test air from HVAC equipment. Backlit simultaneous display of CO2 level, humidity and air temperature, or the user may choose a rotating display of dew point and wet bulb temperature instead of air temperature. Also calculates TWA (Time Weighted Average) and STEL (Short-Term Exposure Limit). Simple user calibration of CO2 and RH. Features audible C02 threshold alarms, min/max/ave, hold and a USB computer interface. NDIR (non-dispersive infrared) technology ensures long-term accuracy, stability and reliability. Comes in a hard carrying case with 4 AA batteries. Weight: 10oz (280g). Dim: 8?" x 3" x 2?" (210 x 75 x 65mm).

Available in a range of weights and flexes each racquet can be customised in length. Formed by our secret 3 stage process each RRIOTT Polymer Head racquet is designed to resist the pitfalls experienced by many mass produced and injection moulded plastic head racquets including air bubbles and shape changing. Each head being lightweight is carefully balanced and spliced onto a premium cane (not polo cane rejects as used by many of our competitors). The Polymer Head Polocrosse Racquet is fitted with the traditional your choice of head and the net is sewn into the head with RRIOTT Polocrosse's special Nylon line that resists abrasion and enhances the life of your racquet. As with our Split Cane Racquets our Polymer Head Racquets are popular amongst Australian National Tiles players but they are being used by some of the best players in the world having represented countries such as Ireland and Zimbabwe, NZ and Canada in the hands of test players throughout these countries. We receive continual compliments from National and International players alike including "Thankyou so much this has been the best racquet I have ever had, it has been my main racquet at every nationals since I got it in 2000 and I am still using it this weekend " Kylie Dowling Talking about our polymer head racquets at the 2007 World Cup (Australian World Cup and WA Rep Player)

Smithsonian description: Horten craftsmen built this Horten III h, Werk Nr. 31, in 1944 at Gottingen. Uncertainty surrounds the subtype designation 'h,' but the glider probably first flew as a two-place Horten III g, and then Reimar modified it into a single-seat glider, installed special test apparatus, and changed the designation to 'III h. During September 1944, Josef Eggert of Zimmer Unter den Burg, a small town near Rottweil, Germany, flew the unmodified III g 20 times and amassed 14 hours and 17 minutes of total flight time. Eggert reported excellent handling qualities, but he apparently chose not to grapple with adverse yaw because he commented specifically on the very tight but flat turns that were possible using only the drag rudders. Eggert warned that stall recovery was good but only when the aircraft was properly trimmed. The special equipment consisted of a portable box-shaped device, approximately one meter square and half-a-meter wide, rested behind the pilot's seat. Atop the box a sprocket and chain drove cables leading forward past the pilot's left shoulder. A boom projected from the lower leading edge of the center section, right of the nose, and it apparently supported a precision angle-of-attack instrument. Remnants of two other crude but functional devices that precisely measured yaw remain fitted to the center section today. Clearly the sailplane featured in a flight test program but more specific information remains unknown. Photographs are all that remain of the box, sprocket, chain, boom and drogue device. These items were stripped from the glider long before transfer to the National Air Museum (it became the NASM in 1966).

Air Quality, Fourth Edition
Ozone-destroying chemicals, greenhouse gases, and dangerous airborne substances that were once thought to be benign are the most urgent issues facing air pollution control experts. Students need a thorough, updated reference that explores these current trends while also covering the fundamental concepts of this emerging discipline.

A new revision of a bestseller, Air Quality, Fourth Edition provides a comprehensive overview air quality issues, including a better understanding of atmospheric chemistry, the effects of pollution on public health and the environment, and the technology and regulatory practices used to achieve air quality goals.

New sections cover toxicological principles and risk assessment. The book also contains revised discussions on public policy concerns, with a focus on air quality standards for ozone depletion and global warming, and the health effects of particulate air pollutants.

This edition continues to serve as a very readable text for advanced level undergraduate and early graduate study in environmental science, environmental management, and in programs related to the study of public health, industrial hygiene, and pollution control.
