Download or read book Soil Cutting and Tillage written by E. McKyes and published by Elsevier. This book was released on 1985-10-01 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: After giving a brief history of tillage practices and implements used throughout the world dating back to ancient times, this book goes on to describe the basic soil mechanics techniques needed to calculate the forces developed in soil by simple-shaped cutting tools. The methods of measuring soil mechanical properties, water pressure in soil and shear rate effects are touched upon. A review is given of two and three dimensional soil cutting mathematical mechanics models to predict soil cutting forces and soil volumes disturbed by cutting and tillage tools, as well as the state-of-the-art of soil loosening, structural rearrangement and plant growth as affected by tillage tools. The author also includes an introduction to the analysis of traction machines. There are many numerical examples of mechanical analyses and predictions worked out in the various sections of the book as well as numerous unsolved problems at the end of a number of the chapters.Written in a textbook style, this monograph is ideal for anyone wanting to learn modern techniques for the mechanical description of soil cutting and tillage forces and soil volumes disturbed. It also provides a reference for analytical formulae and calculated force forces. It will be of interest to universities and colleges worldwide which have Agricultural Engineering Programs, Civil and Mechanical Engineering schools which specialize in soil mechanics and construction machinery as well as to research stations worldwide with interests in soil tillage, soil physics etc.

Download or read book Agricultural Soil Mechanics written by A. J. Koolen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared with forces occurring in soil mechanics problems in civil engineering, the forces that are applied to soil in farming operations generally have a short duration, less than a few seconds, a small loaded area, no more than a few square decimeters, and small intensities, 10 bar being a high value. On the other hand, soil properties vary widely between those of a weak mud and a stone-like dry soil. Tillage and related applications of force to soil are practiced worldwide in farming. Tillage operations are performed on one hectare of land for every three human beings. This means that for the food production for each individual daily, something like one cubic meter of soil is stirred, or about 20 times his body weight. Theoretical knowledge of this most common human activity, which largely determines the surface shape of the fertile part of the earth, is still very limited. In this book the authors have tried to give an outline of the present state of the art. One of the starting points was a course in soil dynamics taught by the authors at the Agricultural University at Wageningen, The Netherlands. We hope to reach interested readers who have no more theoretical knowledge than high school level, as well as readers who want to go beyond the level of a third year university student. For the chapter on wheels and tires we received substantial support from F. G. J. Tijink of the Tillage Laboratory at Wageningen.

This book was released on 2019-04-15 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2018 in the subject Engineering - Mechanical Engineering, Junagadh Agricultural University (College of Agril Engineering & Technology), course: M.Tech Thesis, language: English, abstract: The objectives of this study are to develop a mini tractor mounted clod crusher, to evaluate the performance of the developed machine and to work out economics of the machine. In tillage tools used in India faces problem like, poor soil-tire interface, clod formation, compaction due to heavy traffic and timeliness in operation. Hence, it was planned to fabricate three different types of clod crusher and to evaluate its performance with clod crusher implements. To achieve this objective a prototype implement consisting of three different types of clod crusher cylinders’ like as square spike, round spike and spiral arrangement of spike were developed costing Rs. 7000/- per each cylinder. The newly developed implement was tested in field condition to evaluate its performance. Their performance results were analyzed in terms of tilling quality of soil and machine parameters. The effects of treatments on soil physical properties like soil bulk density, clod MWD were evaluated. Machine performance parameters like fuel consumption, field efficiency and cost of operation were also studied. Better performance in terms of tilling quality of soil was obtained using clod crusher (square spike) attachment to cultivator. The optimum values of clod MWD, clod crushing field efficiency and fuel consumption were found 13.64 mm, 78.37 % and 7.02 lit/ha respectively. The operating cost were found 882, 1050 and 988 ₹/ha in square spike, round spike and spiral arrangement respectively. Using clod crusher attachment to cultivator a farmer can save more rupees against another implement which is used for seed bed preparation.

Download or read book Managing the Undesirables written by Michel Agier and published by Polity. This book was released on 2011-01-25 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Official figures classify some fifty million of the world’s people as 'victims of forced displacement'. Refugees, asylum seekers, disaster victims, the internally displaced and the temporarily tolerated - categories of the excluded proliferate, but many more are left out of count. In the face of this tragedy, humanitarian action increasingly seems the only possible response. On the ground, however, the 'facilities' put in place are more reminiscent of the logic of totalitarianism. In a situation of permanent catastrophe and endless emergency, 'undesirables' are kept apart and out of sight, while the care dispensed is designed to control, filter and confine. How should we interpret the disturbing symbiosis between the hand that cares and the hand that strikes? After seven years of study in the refugee camps, Michel Agier reveals their 'disquieting ambiguity' and stresses the imperative need to take into account forms of improvisation and challenge that are currently transforming the camps, sometimes making them into towns and heralding the emergence of political subjects. A radical critique of the foundations, contexts, and political effects of humanitarian action.
Download or read book Mein Kampf written by Adolf Hitler and published by ببلومانيا للنشر والتوزيع. This book was released on 2024-02-26 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: Madman, tyrant, animal—history has given Adolf Hitler many names. In Mein Kampf (My Struggle), often called the Nazi bible, Hitler describes his life, frustrations, ideals, and dreams. Born to an impoverished couple in a small town in Austria, the young Adolf grew up with the fervent desire to become a painter. The death of his parents and outright rejection from art schools in Vienna forced him into underpaid work as a laborer. During the First World War, Hitler served in the infantry and was decorated for bravery. After the war, he became actively involved with socialist political groups and quickly rose to power, establishing himself as Chairman of the National Socialist German Worker's party. In 1924, Hitler led a coalition of nationalist groups in a bid to overthrow the Bavarian government in Munich. The infamous Munich "Beer-hall putsch" was unsuccessful, and Hitler was arrested. During the nine months he was in prison, an embittered and frustrated Hitler dictated a personal manifesto to his loyal follower Rudolph Hess. He vented his sentiments against communism and the Jewish people in this document, which was to become Mein Kampf, the controversial book that is seen as the blue-print for Hitler's political and military campaign. In Mein Kampf, Hitler describes his strategy for rebuilding Germany and conquering Europe. It is a glimpse into the mind of a man who destabilized world peace and pursued the genocide now known as the Holocaust.
