Facts about flying wings. A primer on all-wing aircraft - PDF
نویسندگان: خلاصه: For many years airplane designers have realized that by reducing parasite drag. that drag caused by the shape or form of the aireraft, its performance could be greatly inereased. Early steps in this direction were the changes from biplane to monoplane designs, the elimination of external struts and wires, the incorporation of retractable landing gears, ete. In spite of all these advaneements, the average conventional airplane of today has two to four times the drag that would be necessary if all its functions could be incorporated within its wing alone.

Lavender Fields: Black Women Experiencing Fear, Agency, and Hope in the Time of COVID-19 - Original PDF
نویسندگان: خلاصه: I start this book on African/Black women’s testimonies of living with COVID-19 by situating myself and my role in it. Over my twenty-plus years as an academician, I have evolved. I started simply wanting to be a political scientist who focused on Black women and public policy. I saw my work as an extension of me, but not in the way I do at this stage of my career. There was a shift in my approach to being an academician at some point. I started journaling about being a storyteller of Black women’s stories. Research, what I had been trained in, took a back seat, and the notion of storytell- ing became more prominent. I cannot explain this shift, and I have learned that some things need not be explained over time. Sometimes, Black women simply know (see Hill Collins 2000). Then COVID-19 hit. At some point during shelter in place—I have lost count of how long I have been at home—the Black feminine ancestors whispered to me. They called on me to undertake this project on Black women and COVID-19. I resisted. The project felt too big for me. I was worried that I could not do it and do it well. I went out into my garden. The energy of the ancestors deepened, and the call seemed to wrap itself around me in a way that would not release me. I did not feel threatened. But I resisted. I stayed in my gar- den for hours in my efforts to resist—weeding, tending, and avoiding. Finally, the heat of the day caught up to me, and I slowly made my way inside. I needed to find something else to occupy my mind, something that allowed me to continue avoiding the call for this project
Hope for a Heated Planet: How Americans Are Fighting Global Warming and Building a Better Future - Original PDF
نویسندگان: خلاصه: am finishing this book in the final days of the George W. Bush adminis- tration. For those of us who love the environment and long for peace, it has been a dark time. Through it, I have often thought of the words of the poet Theodore Roethke that I first heard from scholar and activist Robert Jay Lifton: “In a dark time, the eye begins to see.” The first light of dawn is now visible as the Democratic candidate, Senator Barack Obama, pushed by a growing grassroots movement, embraces action on climate change. To a lesser degree, though far more than President Bush, so does the Republican contender, Senator John McCain. That was far from the case when I began this project at the height of the president’s wartime popularity. This has turned out to be a book as much about hope and democracy as it is about global warming. Its central theme is that you and I can change history. What we believe, what actions we take, actually matter. It is an idea central to democracy. And it should give us hope. I disagree, strongly, with those who believe the American public has turned into a hopeless gaggle of consumers and couch potatoes who are content to let others rule their lives—or destroy the planet. At the height of President Bush’s popularity and influence it may have appeared that way. But national security and environmental degradation (especially global climate change) are complex, difficult, and abstract sub- jects. It has taken some time for us Americans to grasp the gravity of our situation, from melting ice caps to Iraq. This is especially true when our media mostly cover the White House and the Pentagon—regardless of the occupants—and report each utterance as gospel. Meanwhile, most of us are busy with jobs, families, and problems near home that we can actually see and do something about. The result has been that global warming—caused by the vast outpour- x P REFACE ings of carbon dioxide (CO2) and other pollutants from our cars, buildings, and factories—has increased and is picking up speed. But at the same time, so has a growing and revived environmental movement. It is joined now with new allies from the religious community, business, labor, medical and public health professionals, educators, and more. This new climate move- ment has deep roots in the big environmental groups, too often ignored or derided, that have been working to warn us and prevent global climate change since the elder George Bush’s administration in the 1980s. Their work is now bearing fruit. The public is becoming aroused and engaged. And, as a result, we will have a new, much more climate-friendly president and Congress in 2009. This book tells that story and also ex- plains the basics of climate change and its effects on human health and well-being—not just on polar bears and penguins. But Hope for a Heated Planet is finally about solutions to our dilemma. I’ve tried to give you the best steps you can take, both personal and political, to make a difference and to get involved. Like most authors, I like to imagine, of course, that our new president will take to heart every word I have poured out here. But even more impor- tant is that you do. My mother, Margaret Kirkland Musil, died after ninety- one wonderful years as I was writing. She taught me to love life, to love nature, to learn, to have faith, and to act on my beliefs. My first grandchild, Catherine Kirkland Unruh, was born shortly after. She will need the same lessons. So will all our children and grandchildren. Global climate change, we now know, can be prevented by building a vi- brant, healthy economy that does away with the belching furnaces, smoke- stacks, and combustion engines from the outmoded technologies of the nineteenth and twentieth centuries. But in a democracy, that will depend not on our new president, or the one after that. It is up to us. And the signs now are that many, many citizens and their organizations in this great na- tion are indeed aroused. But to prevail, we will need even more. That is really why I have written. I want you and your family and friends to join with me and millions of other Americans in making history. Nobody else can, or should, do it for you
