Wraps. Condición: Good. v, 74 pages. Illustrations. Glossary. NASA Educational Materials. NASA Educational Resources. Scuff on title page. Tear at page 73/74. Cover has some wear, soiling, and corner crease. This was prepared under the auspices of the National Aeronautics and Astronautics Administration, Office of Live and Microgravity Sciences and Applications, Microgravity Science and Applications Division and Office of Human Resources and Education, Education Division, The term micro-g environment (also µg, often referred to by the term microgravity) is more or less a synonym of weightlessness and zero-g, but indicates that g-forces are not quite zero, just very small. The symbol for microgravity, µg, was used on the insignias of Space Shuttle flights STS-87 and STS-107, because these flights were devoted to microgravity research in low Earth orbit. A "stationary" micro-g environment[2] would require traveling far enough into deep space so as to reduce the effect of gravity by attenuation to almost zero. This is the simplest in conception, but requires traveling an enormous distance, rendering it most impractical. For example, to reduce the gravity of the Earth by a factor of one million, one needs to be at a distance of 6 million kilometers from the Earth, but to reduce the gravity of the Sun to this amount one has to be at a distance of 3.7 billion kilometers. (The gravity due to the rest of the Milky Way is already smaller than one millionth of the gravity on Earth, so we do not need to move away further from its center[citation needed]). Thus it is not impossible, but it has only been achieved so far by four interstellar probes (Voyager 1 and 2, part of the Voyager program, Pioneer 10 and 11 part of the Pioneer program) and they did not return to Earth. To reduce the gravity to one thousandth of that on Earth's surface, one needs to be at a distance of 200,000 km. At a distance relatively close to Earth (less than 3000 km), gravity is only slightly reduced. As an object orbits a body such as the Earth, gravity is still attracting objects towards the Earth and the object is accelerated downward at almost 1g. Because the objects are typically moving laterally with respect to the surface at such immense speeds, the object will not lose altitude because of the curvature of the Earth. When viewed from an orbiting observer, other close objects in space appear to be floating because everything is being pulled towards Earth at the same speed, but also moving forward as the Earth's surface "falls" away below. All these objects are in free fall, not zero gravity.…

Taschenbuch. Condición: Neu. Neuware -Dieses Buch führt in die Grundlagen der Umweltökonomik ein, stellt aber auch aktuelle Forschungsfragen vor.Umweltökonomik bedeutet, nach Mitteln zur möglichst effizienten Bereitstellung von Umweltgütern wie etwa sauberes Wasser und Klimaschutz zu suchen.Die Theorie externer Effekte sowie die Besonderheiten von Umweltgütern werden ausführlich erläutert, ebenso umweltpolitische Instrumente - Steuern, Emissionshandel und Auflagen - zur Lösung von umweltrelevantem Marktversagen. Dabei liegt ein Fokus auf Anwendungsorientierung und verständliche Darstellung mit geringem Einsatz formaler Methoden. Fallstudien beschäftigen sich mit externen Kosten des Verkehrs, der Ökologischen Steuerreform, dem EU-Emissionshandel, Dieselfahrverboten und dem Pariser Klimaabkommen. Ein Themenschwerpunkt gilt dem Klimawandel und der Klimapolitik. 284 pp. Deutsch.…
