Ferroelectric Emission Cathodes for Low-Power Electric Propulsion
Low- or no-flow electron emitters are required for low-power electric thrusters, spacecraft plasma contactors, and electrodynamic tether systems to reduce or eliminate the need for propellant/expellant. Expellant-less neutralizers can improve the viability of very low-power colloid thrusters, field emission electric propulsion devices, ion engines, Hall thrusters, and gridded vacuum arc thrusters. The NASA Glenn Research Center (GRC) is evaluating ferroelectric emission (FEE) cathodes as zero expellant flow rate cathode sources for the applications listed above. At GRC, low voltage (100s to approx. 1500 V) operation of FEE cathodes is examined. Initial experiments, with unipolar, bipolar, an...
Two Little Witches
If one little witch meets one little witch, that makes... two little witches going trick-or-treating, and when two little witches meet a clown, a cat and other dressed-up friends, it adds up to a spooky Halloween counting book.
Freire and Education
One of the most influential educational philosophers of our times, Paulo Freire contributed to a revolutionary understanding of education as an empowering and democratizing force in the lives of the disenfranchised. In this deeply personal introduction to the man and his ideas, Antonia Darder reflects on how Freire’s work has illuminated her own life practices and thinking as an educator and activist. Including both personal memories and a never-before published, powerful dialogue with Freire himself, Darder offers a unique "analysis of solidarity," in mind and spirit. A heartfelt look at the ways Freire can still inspire a critically intellectual and socially democratic life, this book is certain to open up his theories in entirely new ways, both to those already familiar with his work and those coming to him for the first time.
The Neighborhood
From the Nobel Laureate comes a politically charged detective novel weaving through the underbelly of Peruvian privilege, translated by Edith Grossman. In the 1990s, during the turbulent and deeply corrupt years of Alberto Fujimori's presidency, two wealthy couples of Lima's high society become embroiled in a disturbing vortex of erotic adventures and politically driven blackmail. One day Enrique, a high-profile businessman, receives a visit from Rolando Garro, the editor of a notorious magazine that specializes in salacious exposés. Garro presents Enrique with lewd pictures from an old business trip and demands that he invest in the magazine. Enrique refuses, and the next day the pictures ...
Badenheim Nineteen-thirty-nine
A tale of Europe in the days just before the war. It tells of a small group of Jewish holiday makers in the resort of Badenheim in the Spring of 1939. Hitler's war looms, but Badenheim and its summer residents go about life as normal."
Improving Urban Schools: Leadership And Collaboration
Drawing on research evidence, Improving Urban Schools addresses the question of how primary and secondary urban schools can be improved in a more inclusive way. The authors argue that urban schools and their communities have within them expertise that tends to be overlooked, and latent creativity that should be mobilised to move thinking and progress forward. They show that new approaches to leadership, various forms of collaborative school-to-school partnerships, and major changes in national policy development are needed to make use of this untapped energy.
Celtic Wonder Tales Retold
Brigit ceased to sing, and there was silence for a little space in Tir-na-Moe. Then Angus said: "Strange are the words of your song, and strange the music: it swept me down steeps of air--down--down--always further down. Tir-na-Moe was like a dream half-remembered. I felt the breath of strange worlds on my face, and always your song grew louder and louder, but you were not singing it. Who was singing it?" "The Earth was singing it." "The Earth!" said the Dagda. "Is not the Earth in the pit of chaos? Who has ever looked into that pit or stayed to listen where there is neither silence nor song? " "O Shepherd of the Star-Flocks, I have stayed to listen. I have shuddered in the darkness that is ...
