The Untold Stories of African Agriculture: Lessons from Ethiopia
by Melaku Admasu Seid Ahmed Kemal Getinet Alemaw Dessie Ambaw Gashawbeza Ayalew Workneh Ayalew Dr Amsalu Ayana Ashenafi Ayano Ferdu Azerefegne Endashaw Bekele Getachew Belay Terefe Belehu Mintewab Bezabih Asmare Dagnew Maru Degefa Mulat Demeke Minyahel Fekadu Daneal Fekersillassie Regassa Feyissa Asnake Fikre Messele Fisseha Amare Fufa Muluken Goftishu Endeshaw Habte Konjit Hailu Karta Karke Kalsa Girma Tesfahun Kassie Friew Kelemu Tolera Keno Rahwa Kidane Berga Lemaga Abebe Menkir Takele Negewo Hawani Negussie Mesfin Shenkut Amare Tegbaru Kindie Tesfaye Taye Tessema Melaku Wale Wondimagegnehu Mersie Zerihun Yemataw Firehun Yirefu Mikael Fisseha Yohannes Engida Zemedagegnehu Olubunmi A. BosseyThis landmark volume presents the results of a comprehensive and coherent in-depth assessment of Ethiopian agriculture and draws lessons from it to generate actionable recommendations that will inform policy decisions and priority setting for agricultural transformation across Africa. Policy makers in Africa are faced with the challenges of ensuring food and nutrition security and the economic wellbeing of their rapidly growing populations while at the same time maintaining the integrity of their natural resource base. Between 2000 and 2021, 74% of the growth in overall crop production on the continent was derived from increases in land area expansion, while increases in yield contributed only 26% of the growth. This unchecked expansion of land use puts the sustainability of the natural resource base under severe pressure. Even though some countries have made substantial increases in their farm productivity over the last two decades, the overall performance for Africa is far behind other regions. For the most part, in Africa, agriculture is not fulfilling its expected functions of food and nutrition security, increased export earnings, import substitution, and raw material supply for local industries. Attempts have been made to transform African agriculture over the years, but few countries have succeeded in achieving sustainable change. Using examples from Ethiopia this book identifies the major factors for success and the root causes of underperformance, and offers evidence-based recommendations for future decision making, policy change and the creation of growth. This book: · Draws on a unique set of case studies from Ethiopia described and told from a truly African perspective. · Emphasises to policy makers in Africa that development cannot be outsourced and there are no shortcuts; it is only through consistent effort and sustained support for their agricultural research and development that positive change can be brought about. · States that past agricultural development efforts by the international community have not properly included a strong African voice, and that therefore, all future academic research, policies and strategies dealing with the continent's agriculture and food security should be formulated by Africa's own leading thinkers and experts. · Is not a polemic; its arguments are knowledge and evidence based, building a compelling picture of how agricultural development can be sustained for the future.
The Untold Stories of the Space Shuttle Program: Unfulfilled Dreams and Missions that Never Flew (Springer Praxis Books)
by Davide SivolellaIn September 1969, several months after the Apollo 11 lunar landing, President Richard M. Nixon established the Space Task Force to chart NASA’s path for the decades to come. This imaginative vision was shattered less than six months later when, on January 13, 1970, NASA Administrator Dr. Thomas Paine announced that, owing to funding cuts, only the reusable Space Shuttle could be afforded -- there would be no space station, no return to the Moon, and no missions to Mars. This is a story never before told about the missions and technologies that NASA had begun to plan but never fully realized. The book is a companion to the author’s previous two works on the Space Shuttle. Whereas the first two books showed how the Space Shuttle flew in space and what the program accomplished, this book explains what more the Space Shuttle could have achieved and how the space transportation system could have further matured if circumstances had been otherwise. A final chapter also discusses how some of these plans might be resurrected in future programs.

Up-to-Date Waste-to-Energy Approach
by Petr StehlikPutting forward an up-to-date waste-to-energy approach that combines experience, sophisticated modeling and technical-economic analysis, this book examines the current need for the maximum utilization of energy from waste and the associated environmental impacts. It outlines step-by-step procedures for a complex and original waste-to-energy approach from the idea to its industrial application. With waste incinerators and industrial plants producing large amounts of pollutants, municipalities as well as smaller decentralized operations are beginning to focus on waste research. The principal advantage of utilizing research findings is the ability to apply a complex approach "from idea to industrial implementation" with respect to the needs of the market established by thorough market analysis. This book builds on this concept with an original approach that takes into consideration geographical aspects, the specifics of regions/micro-regions and technological units and/or equipment. Key areas discussed and analyzed in the text include: strategic planning of energy-source locations according to the nature of the respective region or microregion; types and amounts of wastes; logistics etc. using original mathematical models; consideration of on-site processing of various types of waste, taking into account the character of the region (agricultural, industrial etc. ); tailor-made technologies for energy recovery from various types of wastes; implementation of individual technologies with original elements; and support for environmental protection based on advanced flue gas (i. e. off-gas in the case of incineration) cleaning methods.

Upcycling Legume Water: from wastewater to food ingredients
by Luca ServentiFood manufacturing generates an incredibly high volume of wastewater. The legume industry is one of the top contributors to this environmental issue, as soaking and boiling are necessary to transform dried legumes into cooked canned products and other legume-based products, such as soymilk, tofu, hummus and flours. Wastewater must be treated prior to disposal into the environment, thus raising production costs for the food industry. In addition, wastewater contains nutrients that are lost from the food chain after disposal. As water and soluble nutrients are becoming a limited resource, it is critical to optimize food manufacturing at all levels. Recycling Legume Wastewater Into Food Ingredients presents a sustainable solution to this increasing demand for food and water. The text analyses the composition of legume wastewater and its physicochemical properties, including its potential applications in emulsifiers, foaming agents, gelling agents and antistaling ingredients. Early chapters discuss the processing of legumes and the wastewater generation involved. Further sections focus on wastewater generated by soaking and cooking, including the composition, functional properties, and food applications involved in each. Sprouting water, bioactives and applications in edible packaging are also discussed. In presenting a sustainable solution for legume wastewater use, this text is an important key to sustainability in food processing and the reduction of waste.
Updating to Remain the Same: Habitual New Media
by Wendy Hui ChunNew media -- we are told -- exist at the bleeding edge of obsolescence. We thus forever try to catch up, updating to remain the same. Meanwhile, analytic, creative, and commercial efforts focus exclusively on the next big thing: figuring out what will spread and who will spread it the fastest. But what do we miss in this constant push to the future? In Updating to Remain the Same, Wendy Hui Kyong Chun suggests another approach, arguing that our media matter most when they seem not to matter at all -- when they have moved from "new" to habitual. Smart phones, for example, no longer amaze, but they increasingly structure and monitor our lives. Through habits, Chun says, new media become embedded in our lives -- indeed, we become our machines: we stream, update, capture, upload, link, save, trash, and troll. Chun links habits to the rise of networks as the defining concept of our era. Networks have been central to the emergence of neoliberalism, replacing "society" with groupings of individuals and connectable "YOUS." (For isn't "new media" actually "NYOU media"?) Habit is central to the inversion of privacy and publicity that drives neoliberalism and networks. Why do we view our networked devices as "personal" when they are so chatty and promiscuous? What would happen, Chun asks, if, rather than pushing for privacy that is no privacy, we demanded public rights -- the right to be exposed, to take risks and to be in public and not be attacked?

Upper Bound Limit Load Solutions for Welded Joints with Cracks
by Sergey AlexandrovThe present short monograph concerns analytic and semi-analytic techniques for finding an approximate value of the limit load. The limit load is an essential input parameter of flaw assessment procedures. In most cases, finding the limit load involves some numerical calculations of different levels of complexity, including numerical minimization of functions of one or several arguments, the slip-line technique and the finite element method. This book shows in particular how to use singular behavior of the real velocity field in the vicinity of bi-material interfaces in kinematically admissible velocity fields to increase the accuracy of upper bound solutions. An approach to recalculate the limit load for a class of structures with defects with the use of its value for the corresponding structure with no defect is discussed. The upper bound technique is applied to evaluate the limit load of overmatched and undermatched welded joints with cracks subject to various loading conditions of practical importance in conjunction with the aforementioned special techniques.
The Upright Thinkers: The Human Journey from Living in Trees to Understanding the Cosmos
by Leonard MlodinowA few million years ago, our ancestors came down from the trees and began to stand upright, freeing our hands to create tools and our minds to grapple with the world around us. Leonard Mlodinow takes us on a passionate and inspiring tour through the exciting history of human progress and the key events in the development of science. In the process, he presents a fascinating new look at the unique characteristics of our species and our society that helped propel us from stone tools to written language and through the birth of chemistry, biology, and modern physics to today's technological world. Along the way he explores the cultural conditions that influenced scientific thought through the ages and the colorful personalities of some of the great philosophers, scientists, and thinkers: Galileo, who preferred painting and poetry to medicine and dropped out of university; Isaac Newton, who stuck needlelike bodkins into his eyes to better understand changes in light and color; and Antoine Lavoisier, who drank nothing but milk for two weeks to examine its effects on his body. Charles Darwin, Albert Einstein, Werner Heisenberg, and many lesser-known but equally brilliant minds also populate these pages, each of their stories showing how much of human achievement can be attributed to the stubborn pursuit of simple questions (why? how?), bravely asked. The Upright Thinkers is a book for science lovers and for anyone interested in creative thinking and in our ongoing quest to understand our world. At once deeply informed, accessible, and infused with the author's trademark wit, this insightful work is a stunning tribute to humanity's intellectual curiosity. (With black-and-white illustrations throughout.)From the Hardcover edition.
