In 1845, an estimated 2,500 emigrants left Independence and St. Joseph, Missouri, for the Willamette Valley in what was soon to become the Oregon Territory. It was general knowledge that the route of the Oregon Trail through the Blue Mountains and down the Columbia River to The Dalles was grueling and dangerous. About 1,200 men, women, and children in over two hundred wagons accepted fur trapper and guide Stephen Meek's offer to lead them on a shortcut across the trackless high desert of eastern Oregon. Those who followed Meek experienced a terrible ordeal when his memory of the terrain apparently failed. Lost for weeks with little or no water and a shortage of food, the Overlanders encountered deep dust, alkali lakes, and steep, rocky terrain. Many became ill and some died in the forty days it took to travel from the Snake River in present-day Idaho to the Deschutes River near Bend, Oregon. Stories persist that children in the group found gold nuggets in a small, dry creek bed along the way. From 2006 to 2011, Brooks Ragan and a team of specialists in history, geology, global positioning, metal detecting, and aerial photography spent weeks every spring and summer tracing the Meek Cutoff. They located wagon ruts, gravesites, and other physical evidence from the most difficult part of the trail, from Vale, Oregon, to the upper reaches of the Crooked River and to a location near Redmond where a section of the train reached the Deschutes. The Meek Cutoff moves readers back and forth in time, using surviving journals from members of the 1845 party, detailed day-to-day maps, aerial photographs, and descriptions of the modern-day exploration to document an extraordinary story of the Oregon Trail.

Does the material being mined have enough value to be worth processing? Should it be processed immediately or stockpiled? And if multiple processes are available, like heap leaching and milling, which one should be used? A cut-off grade can provide the answers. An Introduction to Cut-off Grade Estimation examines one of the most important calculations in the mining industry. Cut-off grades are essential to determining the economic feasibility and mine life of a project. Increased cut-off grades can reduce political risks by ensuring higher financial returns over a shorter period of time. Conversely, lower cut-off grades may increase project life with longer economic benefits to shareowners, employees, and local communities. Cut-off grades also impact reported reserves, which are closely monitored by stock exchanges and regulatory agencies. Author Dr. Jean-Michel Rendu, an internationally recognized expert in the management, estimation, audit, and public reporting of mineral resources, provides practical insights into this critical variable. You'll learn about minimum cut-off grades, as well as those for deposits containing multiple valuable minerals. Dr. Rendu explains which costs should be included in cut-off grade calculations and considerations when planning open pit, underground, and block and panel caving operations. He shows how to optimize a copper mining project by changing grind size, and demonstrates the relationship between deposit modeling, ore control, and cut-off grades. An Introduction to Cut-off Grade Estimation includes dozens of charts, graphs, and mathematical formulas to explain basic concepts in a simple, step-by-step fashion. It is a "must read" for mine managers, analysts, geologists, mining engineers, and public policymakers who want to stay on the leading edge of their profession.

CUT OFF! When Illusions Surviveis a unique study of dynamics evident in every person, group and culture. This story celebrates human resourcefullness as three survivors battle to overcome the destructive sides of their personalities. What would happen if you were isolated and stranded by a major cataclysm with no idea if the rest of the world survived ? This novel is prompted by our experience following the September 11, 2001 (9/11) shut down after the terrorist attack on the World Trade Center. My wife, our two teenage sons, and I were in a remote Iupiaq Native Alaskan village above the Arctic Circle when all planes were grounded. We were isolated and felt cut off from the rest of the world. My thoughts about the very real possibility that all was lost, brought forth this novel.

The best-known and most sensational event in Vincent van Gogh’s life is also the least understood. For more than a century, biographers and historians seeking definitive facts about what happened on a December night in Arles have unearthed more questions than answers. Why would an artist at the height of his powers commit such a brutal act? Who was the mysterious “Rachel” to whom he presented his macabre gift? Did he use a razor or a knife? Was it just a segment—or did Van Gogh really lop off his entire ear? In Van Gogh’s Ear, Bernadette Murphy reveals, for the first time, the true story of this long-misunderstood incident, sweeping away decades of myth and giving us a glimpse of a troubled but brilliant artist at his breaking point. Murphy’s detective work takes her from Europe to the United States and back, from the holdings of major museums to the moldering contents of forgotten archives. She braids together her own thrilling journey of discovery with a narrative of Van Gogh’s life in Arles, the sleepy Provençal town where he created his finest work, and vividly reconstructs the world in which he moved—the madams and prostitutes, café patrons and police inspectors, shepherds and bohemian artists. We encounter Van Gogh’s brother and benefactor Theo, his guest and fellow painter Paul Gauguin, and many local subjects of Van Gogh’s paintings, some of whom Murphy identifies for the first time. Strikingly, Murphy uncovers previously unknown information about “Rachel”—and uses it to propose a bold new hypothesis about what was occurring in Van Gogh’s heart and mind as he made a mysterious delivery to her doorstep. As it reopens one of art history’s most famous cold cases, Van Gogh’s Ear becomes a fascinating work of detection. It is also a study of a painter creating his most iconic and revolutionary work, pushing himself ever closer to greatness even as he edged toward madness—and one fateful sweep of the blade that would resonate through the ages.

I wrote this booklet because of my concern for what I feel is a great problem in baseball today - the principal essence of the game is missing. The basic fundamentals of the game, those things which make a complete baseball player are not emphasized in baseball today. The lack of the BASICS allows the game to be played in a mediocre fashion. The art of cut-offs and relays requires team work and concentration. It requires complete knowledge of the BASICS and the discipline that goes with doing them over and over. Having an idea on how these are executed and its continuous practice, not only will make the player a better baseball player, but, will also give him a sense of responsibility. This responsibility will stay with the player for life.

An Introduction to Cut-off Grade Estimation examines one of the most important calculations in the mining industry. Cut-off grades are essential to determining the economic feasibility and mine life of a project. Profitability and socioeconomic impact of mining operations are influenced by the choice of cut-off grades. Cut-off grades play a key role in estimating mineral reserves that can be publicly reported. This new edition is easier to read and of greater practical interest to practitioners. The relationship between optimization of net present value, capacity constraints, and opportunity cost is explained in greater detail. A new section discusses blending strategies, which play a critical role in an increasing number of mining operations. Author Jean-Michel Rendu, an internationally recognized expert in the management, estimation, and public reporting of mineral resources, provides practical insights. As a manager in major mining companies, a consultant, and an educator, Rendu has acquired considerable experience in all aspects of mining engineering, experience that was incorporated into this publication.
