Remote earth used

The expression "remote-earth" used means the infinite conductor with practically no resistance which is the earth s mass. [Pg.565]

Abstract For the case of small matter effects V perturbation theory using e = 2V E/ Am2 as the expansion parameter. We derive simple and physically transparent formulas for the oscillation probabilities in the lowest order in e which are valid for an arbitrary density profile. They can be applied for the solar and supernova neutrinos propagating in matter of the Earth. Using these formulas we study features of averaging of the oscillation effects over the neutrino energy. Sensitivity of these effects to remote (from a detector), d > PE/AE, structures of the density profile is suppressed. [Pg.405]

The sun, an important factor to take into account in remote sensing using spectroscopic imaging instruments. The passive optical system and the atmosphere through which the energy passes, both from the sun to the earth s surface and back to the instrument, interferes with the data collected. Atmospheric distortions include the effect of scattered dry air molecules (haze) and absorption by air molecules. [Pg.285]

Although chemical and isotopic analysis by remote sensing using either Earth- or satellite-based instruments play an important role in some cosmochemical studies, laboratory measurements on real samples remain the predominant means of data acquisition. In cosmochemistry, extraterrestrial materials are the most... [Pg.276]

An uninformed farm population cannot be expected to purchase agricultural chemicals without the assistance of appropriate farm organizations. Neither can these farmers be expected to become interested in obtaining the best weapons for fighting insect and disease plagues unless these weapons can be properly demonstrated. DDT, for example, became a household expression the world over not necessarily because of its merits, but because of the way it was used and demonstrated in the most remote parts of the earth. The merits alone of a given product cannot be relied on to build a market for it abroad. This is especially true today with the many new insecticides that cause confusion even to the growers of the United States. [Pg.12]

The need to use multiple extraction to achieve efficient extraction required the development of new types of continuously working extractors, especially mixer-settlers and pulsed columns, which were suitable for remotely controlled operations. These new extractors could be built for continuous flow and in multiple stages, allowing very efficient isolation of substances in high yield. A good example is the production of rare earth elements in >99.999% purity in ton amounts by mixer-settler batteries containing hundreds of stages. These topics will be further developed in Chapters 6 and 7. [Pg.24]

All machines must be well earthed, all their frictional parts being made of bronze, wood etc. If steel parts must be used they should be lubricated profusely, if possible, with solid grease (vaseline, cup grease). Particularly dangerous machines (e.g. corning mills) must be operated by remote control (Fig. 106). [Pg.362]

As reported by Olmez and Gordon (University of Maryland), the concentration pattern of rare earth elements on fine airborne particles (less than 2.5 micrometers in diameter) is distorted from the crustal abundance pattern in areas influenced by emissions from oil-fired plants and refineries. The ratio of lanthanum (La) to samarium (Sm) is often greater than 20 (crustal ratio is less than 6). The unusual pattern apparently results from tlie distribution of rare earths in zeolite catalysts used in refining oil. Oil industry emissions have been found to perturb the rare earth pattern even in very remote locations, such as the Mauna Loa Observatory in Hawaii. [Pg.1326]

The manuf of Nitroglycerin (NG) and of other nitrate esters has been described elsewhere (Refs 7 18), as well as in earlier volumes of this Encyclopedia (Vol 6, G99-R ff Vol 8, N56-R ff). The principle concern in the handling of NG is the control of temp and of pH (Vol 8, N72), Spilled or contaminated material which is not suitable for use is absorbed in sawdust or fuller s earth, and burned in a remote facility. The hazardous material must remain segregated from other trash and handled only by trained personnel (Ref 50)... [Pg.247]

Studies of atmospheric properties using IR spectroscopy techniques have been reported in the literature for nearly 100 years. This paper presents a brief historical review of the development of this area of science and discusses the common features of spectrographic instruments. Two state of the art instruments on opposite ends of the measurement spectrum are described. The first is a fast response iri situ sensor for the measurement of the exchange of CO2 between the atmosphere and the earth s surface. The second is a rocketborne field-widened spectrometer for upper atmosphere composition studies. The thesis is presented that most improvements in current measurement systems are due to painstakingly small performance enhancements of well understood system components. The source, optical and thermal control components that allow these sensors to expand the state of the art are detailed. Examples of their application to remote canopy photosynthesis measurement and upper atmosphere emission studies are presented. [Pg.217]

The development of the relationships between scattered light and aerosols has stimulated the use of radiation transfer theory for remote sensing of particles in planetary atmospheres. Highly sophisticated experimental and theoretical techniques have emerged for the interpretation of observations of sunlight and artificial light sources in the earth s atmosphere. A description of their application depends on further development of the concepts of radiant energy transfer. [Pg.72]
