Hardback. Condizione: New. From the beginning of the space age, scientists and engineers have worked on systems to help humans survive for the astounding 28,500 days (78 years) needed to reach another planet. They've imagined and tried to create a little piece of Earth in a bubble travelling through space, inside of which people could live for decades, centuries, or even millennia. Far Beyond the Moon tells the dramatic story of engineering efforts by astronauts and scientists to create artificial habitats for humans in orbiting space stations, as well as on journeys to Mars and beyond. Along the way, David P. D. Munns and Kärin Nickelsen explore the often unglamorous but very real problem posed by long-term life support: How can we recycle biological wastes to create air, water, and even food in meticulously controlled artificial environments? Together, they draw attention to the unsung participants of the space program-the sanitary engineers, nutritionists, plant physiologists, bacteriologists, and algologists who created and tested artificial environments for space based on chemical technologies of life support-as well as the bioregenerative algae systems developed to reuse waste, water, and nutrients, so that we might cope with a space journey of not just a few days, but months, or more likely, years.…

Softcover. Condizione: Fine. Leichte Gebrauchsspuren; Leichte Verformung / umgeknickte Seiten. ,We wish to suggest a structure for the salt of deoxyribose nucleic acid (D. N. A.). This structure has novel features which are of considerable biological interest", so lauten die ersten Satze des beruhmten Artikels aus dem Jahr 1953, in dem Francis Crick und James Watson eine Doppelhelix-Struktur fur die DNA vorschlugen. Diesen bahnbrechenden Vorschlag hatten sie in enger Verzahnung mit - und nicht immer legitimer Nutzung von - den Arbeiten von Maurice Wilkins und, vor allem, Rosalind Franklin entwickelt. In dem Buch werden die vier entscheidenden Aufsatze dieser Akteure gesammelt reproduziert, gemeinsam mit zwei wichtigen Vorlaufer-Arbeiten (Avery, McLeod & McCarty 1944; Hershey & Chase 1952), die den Weg zu der Entdeckung bahnten. Den Originalpublikationen wird eine allgemeinverstandliche Einleitung vorangestellt, in der die Geschichte dieser Entdeckung nachgezeichnet und in den historischen Kontext eingeordnet wird.…
