Book Description
This book discusses the application of the coupled CFD-DEM approach for simulating the separation of grain and material other than grain in combine harvester cleaning devices. Based on a literature study, it describes the most important influencing factors and presents a database for particle parameterization. It investigates the separation process in two steps with differing levels of process abstraction. The first step involves numerical separation in a vertically oscillating box with airflow, and in the context of a sensitivity study, investigates the effect of selected material, contact and operating parameters on the target variables’ separation time and grain purity. In the second step, the numerical separation process was performed in a 200 mm wide segment of a combine harvester cleaning device. The numerical results were then compared with experimental investigations in order to confirm the method’s applicability.

Book Description
This book contains a classic guide to vintage farming machinery, including detailed descriptions, explanations, and illustrations of the machinery treated. It contains information on the various types of harvesters and other examples of machinery that existed at the time of publication. This is a fascinating work and is thoroughly recommended for anyone interested in farm machinery, especially the history and development thereof. Contents include: “Methods of Harvesting by Combine”, “Main Types of Combine”, “The Threshing Mechanism”, “Handling of the Straw”, “Choice of Crop Varieties”, “Combine Harvester or Binder”, “Combine Harvesters”, etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new introduction on poultry farming.

Book Description
The uptake of agricultural mechanization in Ethiopia is low with less than one percent of agricultural plots plowed with a tractor. However, in recent years the uptake of agricultural machinery has accelerated. We note an impressive increase in imports of combine-harvesters and of tractors, seemingly associated with the increasing costs of agricultural labor and animal traction, substitutes for agricultural mechanization. We estimate that a quarter of the area in Ethiopia planted to wheat – the fourth most important cereal in the country – is currently harvested by combine-harvesters, and they are widely used in the major wheat growing zones in the southeast of the country in particular. Private mechanization service providers have rapidly emerged. Smallholders in these wheat growing zones rely heavily on agricultural machinery rental services for plowing, harrowing, or harvesting. We find that mechanization is associated with significantly lower labor use, and that the adoption of combine-harvesters – but not tractors – is significantly associated with higher yields, seemingly due to lower post-harvest losses. While further expansion of mechanization in the country is desired, given the environmental and financial cost of holding oxen and the higher yields linked with some forms of mechanization, it appears to be hampered by farm structures, particularly small farm sizes and consequent limits in scale; fragmented plots; crop diversity; physical constraints, such as presence of stones, steepness of fields, and soil types; and economic and financial constraints, including limited access to foreign exchange and credit and the still relatively low wages in less commercialized zones.

Book Description
New York Times Bestseller "A moving, beautifully etched picture of America’s lost and profoundly lonely." —Kazuo Ishiguro, author of The Remains of the Day and winner of the 2017 Nobel Prize for Literature “Brilliant . . . Darnielle is a master at building suspense, and his writing is propulsive and urgent; it’s nearly impossible to stop reading . . . [Universal Harvester is] beyond worthwhile; it’s a major work by an author who is quickly becoming one of the brightest stars in American fiction.” —Michael Schaub, Los Angeles Times “Grows in menace as the pages stack up . . . [But] more sensitive than one would expect from a more traditional tale of dread.” —Joe Hill, New York Times Book Review Life in a small town takes a dark turn when mysterious footage begins appearing on VHS cassettes at the local Video Hut. So begins Universal Harvester, the haunting and masterfully unsettling new novel from John Darnielle, author of the New York Times Bestseller and National Book Award Nominee Wolf in White Van Jeremy works at the Video Hut in Nevada, Iowa. It’s a small town in the center of the state—the first a in Nevada pronounced ay. This is the late 1990s, and even if the Hollywood Video in Ames poses an existential threat to Video Hut, there are still regular customers, a rush in the late afternoon. It’s good enough for Jeremy: it’s a job, quiet and predictable, and it gets him out of the house, where he lives with his dad and where they both try to avoid missing Mom, who died six years ago in a car wreck. But when a local schoolteacher comes in to return her copy of Targets—an old movie, starring Boris Karloff, one Jeremy himself had ordered for the store—she has an odd complaint: “There’s something on it,” she says, but doesn’t elaborate. Two days later, a different customer returns a different tape, a new release, and says it’s not defective, exactly, but altered: “There’s another movie on this tape.” Jeremy doesn’t want to be curious, but he brings the movies home to take a look. And, indeed, in the middle of each movie, the screen blinks dark for a moment and the movie is replaced by a few minutes of jagged, poorly lit home video. The scenes are odd and sometimes violent, dark, and deeply disquieting. There are no identifiable faces, no dialogue or explanation—the first video has just the faint sound of someone breathing— but there are some recognizable landmarks. These have been shot just outside of town. In Universal Harvester, the once placid Iowa fields and farmhouses now sinister and imbued with loss and instability and profound foreboding. The novel will take Jeremy and those around him deeper into this landscape than they have ever expected to go. They will become part of a story that unfolds years into the past and years into the future, part of an impossible search for something someone once lost that they would do anything to regain. “This chilling literary thriller follows a video store clerk as he deciphers a macabre mystery through clues scattered among the tapes his customers rent. A page-tuning homage to In Cold Blood and The Ring.” —O: The Oprah Magazine “[Universal Harvester is] so wonderfully strange, almost Lynchian in its juxtaposition of the banal and the creepy, that my urge to know what the hell was going on caused me to go full throttle . . . [But] Darnielle hides so much beautiful commentary in the book’s quieter moments that you would be remiss not to slow down.” —Abram Scharf, MTV News “Universal Harvester is a novel about noticing hidden things, particularly the hurt and desperation that people bear under their exterior of polite reserve . . . Mr. Darnielle possesses the clairvoyant’s gift for looking beneath the surface.” —Sam Sacks, The Wall Street Journal “[Universal Harvester is] constantly unnerving, wrapped in a depressed dread that haunts every passage. But it all pays off with surprising emotionality.” —Kevin Nguyen, GQ.com
