The physical and chemical properties and processes of clouds are of great interest from a variety of perspectives, such as acid deposition, oxidant chemistry, and radiative transfer in the atmosphere. The Kleiner Feldberg Cloud Experiment was conducted in October--November 1990 at the field observatory of Kleiner Feldberg near Frankfurt, Germany, in the Taunus Highlands. The experiment was ...
Fall accidents, which occur as a result of not enough friction available between the floor and shoe bottom for the pedestrian to ambulate without slipping, are responsible for a great number of walkway accidents. For this reason, characterizations of how much friction pedestrians require to ambulate and how much friction is available between the foot or shoe bottom and the walkway surface are of ...
As the use of beryllium grows worldwide, the need for a single source of information on this important but toxic element is of increasing importance. This comprehensive book describes all aspects of the current sampling and analysis techniques for trace-level beryllium in the workplace. It offers both a historical perspective and a description of the state-of-the-art in a single place.It covers ...
This recommended practice describes procedures which may be used to "prove-up" the depth or size of imperfections. Included in this practice are the recommended procedures for ultrasonic prove-up inspection of new pipe using the Amplitude Comparison Technique and the Amplitude- Distance Differential Technique for evaluation of 1) surface breaking imperfections in the body of pipe and 2) surface ...
This study evaluates the impacts of blending practices at municipal wastewater treatment plants on effluent and receiving water quality, and estimates public health risks associated with recreation in surface waters receiving blended flows. Field samples were collected at four municipal wastewater treatment plants for in-plant processes and receiving waters ...
Meteorites - as well as shooting stars and meteors - result from a collision of a solid body from space with our Earth, but only meteorites are able to penetrate the Earth's protective shield, the atmosphere, and fall to the Earth's surface. Before the return of lunar samples, they were the only materials from beyond the Earth which we could take in hand and ...
