Rigor Mortis

An essential book to understanding whether the new miracle cure is good science or simply too good to be true American taxpayers spend $30 billion annually funding biomedical research, but over half of these studies can't be replicated due to poor experimental design, improper methods, and sloppy statistics. Bad science doesn't just hold back medical progress, it can sign the equivalent of a death sentence for terminal patients. In Rigor Mortis, Richard Harris explores these urgent issues with vivid anecdotes, personal stories, and interviews with the top biomedical researchers. We need to fix our dysfunctional biomedical system--before it's too late.

Estimation of the Time Since Death remains the foremost authoritative book on scientifically calculating the estimated time of death postmortem. Building on the success of previous editions which covered the early postmortem period, this new edition also covers the later postmortem period including putrefactive changes, entomology, and postmortem r

Most aircraft of World War II had pictures of sexy girls, tributes to sweethearts, songs and home. The planes were fondly referred to in a feminine manor. That was not the case with this B-17 tail number 42-25233. He was Rigor Mortis.This is the story of Rigor Mortis and his men who flew over 120 missions from North Africa and Italy in 1943 and 1944. This sixteen month story encompasses the 301st, 2nd and 483rd Bombardment Groups of the 12th and 15th Air Forces. It begins with the first crew in Salina, Kansas. Their overseas trip via Brazil, arriving at Biskra, Algeria on New Year's Eve 1942. 25233 and his men flew their first mission on January 2. Some missions would be milk runs, many quite difficult. They all had a cost.Softcover. Black and White. 291 pictures of documents, photos and artifacts.

An antidote to mathematical rigor mortis, teaching how to guess answers without needing a proof or an exact calculation. In problem solving, as in street fighting, rules are for fools: do whatever works—don't just stand there! Yet we often fear an unjustified leap even though it may land us on a correct result. Traditional mathematics teaching is largely about solving exactly stated problems exactly, yet life often hands us partly defined problems needing only moderately accurate solutions. This engaging book is an antidote to the rigor mortis brought on by too much mathematical rigor, teaching us how to guess answers without needing a proof or an exact calculation. In Street-Fighting Mathematics, Sanjoy Mahajan builds, sharpens, and demonstrates tools for educated guessing and down-and-dirty, opportunistic problem solving across diverse fields of knowledge—from mathematics to management. Mahajan describes six tools: dimensional analysis, easy cases, lumping, picture proofs, successive approximation, and reasoning by analogy. Illustrating each tool with numerous examples, he carefully separates the tool—the general principle—from the particular application so that the reader can most easily grasp the tool itself to use on problems of particular interest. Street-Fighting Mathematics grew out of a short course taught by the author at MIT for students ranging from first-year undergraduates to graduate students ready for careers in physics, mathematics, management, electrical engineering, computer science, and biology. They benefited from an approach that avoided rigor and taught them how to use mathematics to solve real problems.

Muscle and Meat Biochemistry teaches the different concepts and topics under the eponymous subject. The book covers the gross and detailed composition and structure of muscles and the relationship of the nervous system with the muscular system; muscle cell differentiation and growth; proteins of the thick filament; and the molecular structure and enzymatic activity of myosin. The text also discusses the proteins found in the thin filament - actin, troponin, and myosin; skeletal muscle growth; protein metabolism; and fiber types. The book also encompasses cardiac and smooth muscle; sarcoplasmic proteins; the connective tissues - collagen, elastin, and ground substance; and the postmortem changes during conversion of muscle to meat. The text is recommended for advanced undergraduate and graduate students, as well as for scientists who would like to know more about muscle biology, muscle physiology, and meat science.

Essentials of Food Science covers the basics of foods, food science, and food technology. The book is meant for the non-major intro course, whether taught in the food science or nutrition/dietetics department. In previous editions the book was organized around the USDA Food Pyramid which has been replaced. The revised pyramid will now be mentioned in appropriate chapters only. Other updates include new photos, website references, and culinary alerts for culinary and food preparation students. Two added topics include RFID (Radio frequency ID) tags, and trans fat disclosures. Includes updates on: food commodities, optimizing quality, laws, and food safety.

Studienarbeit aus dem Jahr 2020 im Fachbereich Tiermedizin / Veterinärmedizin, , Sprache: Deutsch, Abstract: Rigor mortis is Latin for "stiffness of death". It is used medically to describe the stiffness of skeletal muscles that appears soon after death. Fully developed rigor mortis in muscle is characterized by maximum loss of extensibility. Regor mortis can be classified in to three phases, the first phase, when a well-marked rigidity was established in the muscles, the second phase, when the complete rigidity was established and the third phase, where the rigor begin to pass off. Cold-shortening occurs when muscles are exposed to low temperatures (below 10 °C to 15 °C) early post mortem, when ATP and pH levels are still high (pH above 6.2). On the other hand, rigor tension occurs much later and at any temperature between 0 oC and 37 oC, reaching maximum values when ATP levels have been depleted and pH is at a minimum value. Cold shortening decreases tenderness which is due to muscle fiber contractions that occur before the onset of rigor. Different carcasses in the same chiller can undergo cold shortening that deteriorate the tenderness of meat. Toughening due to cold shortening cannot be eliminated by aging of meat. A thumb rule to avoid cold shortening is that the temperature of the muscle should be kept high i-e above 10oC till the pH of meat which is initially 7.0-7.2 at the time of death falls below 6.0.
