Armageddon in Stalingrad by David M. Glantz,Jonathan M. House Pdf
The German offensive on Stalingrad was originally intended to secure the Wehrmacht's flanks, but it stalled dramatically in the face of Stalin's order: "Not a Step Back!" The Soviets' resulting tenacious defense of the city led to urban warfare for which the Germans were totally unprepared, depriving them of their accustomed maneuverability, overwhelming artillery fire, and air support-and setting the stage for debacle. Armageddon in Stalingrad continues David Glantz and Jonathan House's bold new look at this most iconic military campaign of the Eastern Front and Hitler's first great strategic defeat. While the first volume in their trilogy described battles that took the German army to the gates of Stalingrad, this next one focuses on the inferno of combat that decimated the city itself. Previous accounts of the battle are far less accurate, having relied on Soviet military memoirs plagued by error and cloaked in secrecy. Glantz and House have plumbed previously unexploited sources—including the archives of the People's Commissariat of Internal Affairs (NKVD) and the records of the Soviet 62nd and German Sixth Armies—to provide unprecedented detail and fresh interpretations of this apocalyptic campaign. They allow the authors to reconstruct the fighting hour by hour, street by street, and even building by building and reveal how Soviet defenders established killing zones throughout the city and repeatedly ambushed German spearheads. The authors set these accounts of action within the contexts of decisions made by Hitler and Stalin, their high commands, and generals on the ground and of the larger war on the Eastern Front. They show the Germans weaker than has been supposed, losing what had become a war of attrition that forced them to employ fewer and greener troops to make up for earlier losses and to conduct war on an ever-lengthening logistics line. Written with the narrative force of a great war novel, this new volume supersedes all previous accounts and forms the centerpiece of the Stalingrad Trilogy, with the upcoming final volume focusing on the Red Army's counteroffensive.
Every Farm a Factory by Deborah Kay Fitzgerald Pdf
During the early part of the 20th century farming in America was transformed from a pre-industrial to an industrial activity. This book explores the modernization of the 1920s, which saw farmers adopt not just new technology, but also the financial cultural & ideological apparatus of industrialism.
Neuroscientist and surgeon Joseph Maroon looks at recent scientific breakthroughs identifying a group of natural substances--including the much-publicized molecule resveratrol--that can actually activate a specific set of genes that promote a longer, healthier life. These substances, which make red wine, dark chocolate, and green tea good for us, appear to stave off a wide array of age-related diseases and keep us feeling young and vital. Only recently have scientists discovered how to isolate resveratrol and concentrate it into an affordable and safe supplement. Already, more than 200 supplements featuring resveratrol have flooded the market, and there are more on the way. What is a consumer to look for? Since resveratrol is a natural substance, can you get enough of it through diet alone, or should you combine diet with a supplement? And what lies on the horizon from the pharmaceutical industry? These questions and many more are answered here. --From publisher description.
Heavy-Duty Wheeled Vehicles by Boris Nikolaevich Belousov,Sergey D Popov Pdf
Heavy-duty wheeled vehicles (HDWVs) are all-wheel-drive vehicles that carry 25 tons or more and have three or more axles. They transport heavy, bulky cargo such as raw minerals, timber, construction materials, pre-fabricated modules, weapons, combat vehicles, and more. HDWVs are used in a variety of industries (mining, logging, construction, energy) and are critical to a country’s economy and defense. These vehicles have unique development requirements due to their high loads, huge dimensions, and specific operating conditions. Hauling efficiencies can be improved by increasing vehicle load capacity; however capacities are influenced by legislation, road limits, and design. Designing HDWVs differs from other multi-purpose all-wheel-drive vehicles. The chassis must be custom-designed to suit the customer’s particular purpose. The number of axles is another variable, as well as which ones are driving and which are driven. Tires are also customizable. Translated by SAE from Russian, this book narrates the history of HDWVs and presents the theory and calculations required to design them. It summarizes results of the authors’ academic research and experience and presents innovative technical solutions used for electric and hydrostatic transmissions, steering systems, and active safety of these vehicles. The book consists of three parts. Part one covers HDWV design history and general design methods, including basic vehicle design, and evaluating HDWV use conditions. Part one also covers general operation requirements and consumer needs, and a brief analysis of structural components of existing HDWVs and prototypes. Part two outlines information needs for designing HDWVs. Part three reviews basic theory and calculation of innovative technical solutions, as well as special requirements for component parts. This comprehensive title provides the following information about HDWVs: • History of design and manufacture. • Manufacturers’ summary design data. • Background data on sample vehicles. • Component calculation examples. • Overview of motion theory, which is useful in design and placement of bulky cargo.
Market imperfections for tractor service provision in Nigeria by Takeshima, Hiroyuki Pdf
In Nigeria, despite the scarcity of tractors, average horsepower and prices of tractors appear high. These patterns are different from the experiences in other parts of the world where initially tractor horsepower was often smaller, such as Asia, or farmers were better endowed with land and wealth, such as Latin America. In Nigeria, joint ownership of tractors is rare, and formal loans are often unavailable due to high transactions costs. IFPRI’s survey in Kaduna and Nasarawa states in 2013 suggested that the spatial mobility of tractors is generally low and the use of tractors is highly seasonal. There do not seem to be plausible explanations for the seeming dominance of large tractor use based on available information on prices and soils. Nevertheless, these patterns seem driven by the own initiative of the private sector rather than by government policies. Indivisibility of large tractors and limited mobility of supplies may cause imperfections in the custom tractor hiring market. In order to distinguish the impacts of technology adoption at the extensive margin from those at the intensive margin, in the empirical analyses for the research presented here we tested these hypotheses focusing on the differences among marginal adopters of tractor hiring services and non-adopters with similar characteristics. The results are three-fold: (1) adoptions patterns of tractor services are partly explained by basic factor endowments, suggesting that the market for custom hiring is in some way functioning efficiently in response to economic conditions; (2) adoptions are, however, affected by supply-side factors, including the presence of large farm households (and thus potential tractor owners) within the district, and (3) per capita household expenditure level differs significantly between the marginal adopters and non-adopters with similar characteristics. This difference seems to arise from adoption per se, rather than the intensity of adoption, which is consistent with the hypothesis of imperfection in the custom tractor hiring market.
