Taschenbuch. Condizione: Neu. Neuware - A study of the magnetic and structural properties of the alloy Y(1-x)Pr(x)Ba2Cu3O(7-delta) of 0%, 2%, and 4% doping of praseodymium is presented. The resulting oxides of the alloy series are a high-temperature superconductor Y-Ba-Cu-O, which has an orthorhombic superconducting crystal-lattice. Magnetic relaxation studies have been performed on the Y-Pr-Ba-CuO bulk samples for field orientation parallel to the c-axis, using a vibrating sample magnetometer. Relaxation was measured at several temperatures to obtain the irreversible magnetization curves used for the Bean model. Magnetization current densities were derived from the relaxation data. Field and temperature dependence of the logarithmic flux-creep relaxation was measured in critical state. The data indicates that the effective activation energy U(eff) increases with increasing T between 77 K and 86 K. Also, the data shows that U(eff)(T) and superconducting transition temperature, Tc, decreased as the lattice parameters increased with increasing Pr ion concentration, x, for the corresponding Y(1-x)Pr(x)Ba(x)Cu3O(7-delta) oxides. One contribution to Tc decrease in this sampling is suspected to be due to the larger ionic radius of the Pr(3+) ion. The upper critical field (H(sub c2)) was measured in the presence of magnetic field parallel to the c axis. A linear temperature dependence with H(sub c2) was obtained.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Kasper Wise has a goal of running the 1600 meters in the low four twenties, to gain an athletic college scholarship that will pay for his college-but he attends a small country school, with his two brothers and cousin, that has no history of developing outstanding distance runners. Then Kasper finds he can gain admittance to a major university, if he can excel on a physics examination the school offers. He devotes much of his time studying for this very difficult test and then he must push his body to its physical limits in running everyday. Examining their training regimen and methods to solve physics problems gets detailed attention. The community, confronted by some adverse activities and a stalker following the team's one girl distance runner, leads Kasper into situations that threatens and interferes with his running and studies. Kasper must use his knowledge of the German language to confront a situation and brute intelligence to solve a coded message for an English assignment. Kasper is constantly being pushed to his limits to complete his goals and juggle his limited resources available.…
