This book was released on 2018-06-11 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this design guide is to present information for understanding and mitigating the potential hazards associated with de-mating and mating powered electrical connectors on space flight vehicles. The process of staging is a necessary function in the launching of space vehicles and in the deployment of satellites, and now in manned assembly of systems in space. During this electrical interconnection process, various environments may be encountered that warrant the restriction of the voltage and current present across the pins of an electrical connector prior to separation, mating, or in a static open non-mated configuration. This process is called deadfacing. These potentially hazardous environments encompass the obvious explosive fuel vapors and human shock hazard, to multiple Electro-Magnetic Interference (EMI) phenomena related to the rapid rate of change in current as well as exposure to Radio Frequency (RF) fields.Berki, Joe M. and Sargent, Noel and Kauffman, W.

Download or read book Thimblerig s Ark written by Nate Fleming and published by Lulu.com. This book was released on 2014-07-09 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: You know about Noah, but what about the animals? Thimblerig is a little groundhog with big problems. He's a loner con-artist who's losing his mojo; the wild dogs who run the forest harass him at every turn; he's started having vivid nightmares of apocalyptic floods; and worst of all - he believes he sees unicorns when everyone knows unicorns are only the stuff of legend. But what one animal calls problems, Thimblerig calls opportunity. His problems inspire him to come up with the ultimate con: convincing a group of gullible animals that a world-ending flood is coming, that the fabled unicorns have told him where the only safe place will be, and that only he can lead them to safety. And all for a reasonable price, of course. But when the flood really does come, Thimblerig has a choice to make: either he really does save the ones who have trusted him, or he loses everything. And he discovers that his problems have only just begun.

Download or read book To Orbit and Back Again written by Davide Sivolella and published by Springer Science & Business Media. This book was released on 2013-08-27 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Space Shuttle has been the dominant machine in the U.S. space program for thirty years and has generated a great deal of interest among space enthusiasts and engineers. This book enables readers to understand its technical systems in greater depth than they have been able to do so before. The author describes the structures and systems of the Space Shuttle, and then follows a typical mission, explaining how the structures and systems were used in the launch, orbital operations and the return to Earth. Details of how anomalous events were dealt with on individual missions are also provided, as are the recollections of those who built and flew the Shuttle. Many photographs and technical drawings illustrate how the Space Shuttle functions, avoiding the use of complicated technical jargon. The book is divided into two sections: Part 1 describes each subsystem in a technical style, supported by diagrams, technical drawings, and photographs to enable a better understanding of the concepts. Part 2 examines different flight phases, from liftoff to landing. Technical material has been obtained from NASA as well as from other forums and specialists. Author Davide Sivolella is an aerospace engineer with a life-long interest in space and is ideally qualified to interpret technical manuals for a wider audience. This book provides comprehensive coverage of the topic including the evolution of given subsystems, reviewing the different configurations, and focusing on the solutions implemented.

Download or read book Piety in Pieces written by Kathryn M. Rudy and published by Open Book Publishers. This book was released on 2016-09-26 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medieval manuscripts resisted obsolescence. Made by highly specialised craftspeople (scribes, illuminators, book binders) with labour-intensive processes using exclusive and sometimes exotic materials (parchment made from dozens or hundreds of skins, inks and paints made from prized minerals, animals and plants), books were expensive and built to last. They usually outlived their owners. Rather than discard them when they were superseded, book owners found ways to update, amend and upcycle books or book parts. These activities accelerated in the fifteenth century. Most manuscripts made before 1390 were bespoke and made for a particular client, but those made after 1390 (especially books of hours) were increasingly made for an open market, in which the producer was not in direct contact with the buyer. Increased efficiency led to more generic products, which owners were motivated to personalise. It also led to more blank parchment in the book, for example, the backs of inserted miniatures and the blanks ends of textual components. Book buyers of the late fourteenth and throughout the fifteenth century still held onto the old connotations of manuscripts—that they were custom-made luxury items—even when the production had become impersonal. Owners consequently purchased books made for an open market and then personalised them, filling in the blank spaces, and even adding more components later. This would give them an affordable product, but one that still smacked of luxury and met their individual needs. They kept older books in circulation by amending them, attached items to generic books to make them more relevant and valuable, and added new prayers with escalating indulgences as the culture of salvation shifted. Rudy considers ways in which book owners adjusted the contents of their books from the simplest (add a marginal note, sew in a curtain) to the most complex (take the book apart, embellish the components with painted decoration, add more quires of parchment). By making sometimes extreme adjustments, book owners kept their books fashionable and emotionally relevant. This study explores the intersection of codicology and human desire. Rudy shows how increased modularisation of book making led to more standardisation but also to more opportunities for personalisation. She asks: What properties did parchment manuscripts have that printed books lacked? What are the interrelationships among technology, efficiency, skill loss and standardisation?

This book was released on 2012-04-24 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fresh, exhilarating take on one of the world's most popular topics—Paris, the City of Light!—by an acclaimed novelist Rosecrans Baldwin A self-described Francophile since the age of nine, Rosecrans Baldwin had always dreamed of living in France. So when an offer presented itself to work at a Parisian ad agency, he couldn't turn it down—even though he had no experience in advertising, and even though he hardly spoke French. But the Paris that Rosecrans and his wife, Rachel, arrived in wasn't the romantic city he remembered, and over the next eighteen months, his dogged American optimism was put to the test: at work (where he wrote booklets on breastfeeding), at home (in the hub of a massive construction project), and at every confusing dinner party in between. A hilarious and refreshingly honest look at one of our most beloved cities, Paris, I Love You but You're Bringing Me Down is the story of a young man whose preconceptions are usurped by the oddities of a vigorous, nervy metropolis—which is just what he needs to fall in love with Paris a second time.
Download or read book The Pastor written by Eugene H. Peterson and published by Harper Collins. This book was released on 2011-02-22 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Pastor, author Eugene Peterson, translator of the multimillion-selling The Message, tells the story of how he started Christ Our King Presbyterian Church in Bel Air, Maryland and his gradual discovery of what it really means to be a pastor. Steering away from abstractions, Peterson challenges conventional wisdom regarding church marketing, mega pastors, and the church’s too-cozy relationship to American glitz and consumerism to present a simple, faith-based description of what being a minister means today. In the end, Peterson discovers that being a pastor boils down to “paying attention and calling attention to ‘what is going on now’ between men and women, with each other and with God.”
Download or read book The Flat Earth Conspiracy written by Eric Dubay and published by Lulu.com. This book was released on 2014-11-09 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wolves in sheep's clothing have pulled the wool over our eyes. For almost 500 years, the masses have been thoroughly deceived by a cosmic fairy-tale of astronomical proportions. We have been taught a falsehood so gigantic and diabolical that it has blinded us from our own experience and common sense, from seeing the world and the universe as they truly are. Through pseudo-science books and programs, mass media and public education, universities and government propaganda, the world has been systematically brain-washed, slowly indoctrinated over centuries into the unquestioning belief of the greatest lie of all time. A multi-generational conspiracy has succeeded, in the minds of the masses, to pick up the fixed Earth, shape it into a ball, spin it in circles, and throw it around the Sun! The greatest cover-up of all time, NASA and Freemasonry's biggest secret, is that we are living on a plane, not a planet, that Earth is the flat, stationary center of the universe.
