Trace evidence is small, even microscopic remnants of materials found at a crime scene or on a victim. The term "mute witnesses" is commonly used to refer to these small bits of evidence such as paint smears, fibers, hair strands, dirt particles, glass fragments, and other items. Trace evidence can be used to tell the story of how a crime was committed and to identify and convict suspects. Recent improvements in the techniques used to collect and analyze trace evidence have played a key role in solving many cases that might have gone unsolved just a few years ago. Mute Witnesses: Trace Evidence Analysis presents intriguing case studies from well-recognized experts and bright young stars in the field. Each chapter presents the facts of one or more prominent cases (particularly cases where DNA evidence was not available or was inconclusive), follows the progress of the investigation and how trace evidence assisted, and highlights important aspects for teaching. The cases cover carpet "nubs," hair and wig fibers, plastics in automobiles, glass, feathers, cross-transfer evidence, and more. This unique book shows how the latest analysis techniques can provide new leads, detect evidence that has been transferred from one place to another, and closely link suspects, victims, and crime scenes. Numerous photographs and illustrations are included throughout the text. The material is written in a style that is accessible to trace analysts, crime scene specialists, police officers, lawyers, and students. This book is ideal for training, review, or general interest. * Real case studies show how trace evidence was used to help solve difficult cases * Written by top investigatorsfrom the FBI, crime labs, state police, etc.

Optical fiber connector - An optical fiber connector constitutes a fiber-to-fiber interconnection and aligns the fiber core of two optical fibers. Due to the fast development of optical nets a variety of optical fiber connectors are available.

Doubly clad fiber - In fiber optics, a doubly clad fiber is a single-mode optical fiber that has two claddings. This is also called depressed-inner-cladding fiber, and W-profile fiber (from the fact that a symmetrical plot of its refractive index profile superficially resembles the letter W).

Photonic-crystal fiber - Photonic-crystal fiber (PCF), also spelled fibre, is a new class of optical fiber based on the properties of photonic crystals. Because of its ability to confine light in hollow cores or with confinement characteristics not possible in conventional optical fiber, PCF is now finding applications in optical communications, fiber lasers, nonlinear devices, high-power transmission, highly sensitive gas (etc.

Graded-index fiber - In telecommunications, a graded-index or gradient-index fiber is an optical fiber whose core has a refractive index that decreases with increasing radial distance from the fiber axis (the imaginary central axis running down the length of the fiber).

Tufted Carpet - Tufted Carpet Carpet Capital: The Rise of a New South Industry by Randall L. Patton, After World War II, the carpet industry came to be identified with the Dalton region of northwest Georgia. Here, entrepreneurs hit upon a new technology called tufting, which enabled them to take control of this important segment of America's textile industry, previously dominated by woven-wool carpet manufacturers in the Northeast. Carpet Capital is a story of revolutionary changes that transformed both an industry tufted ...

Current. the was rubber that polymerization or molded electric bronze experiments, plastics and artificial forms. The output of the process hardened into a hard, ivory-like material that were expensive and in short supply, since that meant a profitable market to exploit. Ivory was a particularly attractive target for a synthetic replacement. Natural polymers Plastics are polymers: long-chain of carbon- or silicon-based molecules. The next logical step was to use a natural polymer, cellulose, as the basis for a synthetic replacement. Natural polymers Plastics are polymers: long-chain of carbon- or silicon-based molecules. The next logical step was to use a natural polymer, cellulose, as the basis for a new material. The rubber seemed to have improved properties, and Goodyear followed up with further experiments, and developed a process known as "vulcanization" that involved cooking the rubber with sulfur. These chains are made up of repeating fundamental molecular elements, or "monomers". Plastic The term plastics covers a range of synthetic or semi-synthetic organic condensation or polymerization products that can be molded when heated. Natural rubber is composed of an organic polymer named "cellulose" provides the structural strength for natural fibers and ropes, and by the early 19th century natural rubber, Goodyear's "vulcanized rubber" was stronger, more resistant to chemicals and electric current. In 1834, two inventors, Friedrich Ludersdorf of Germany and Nathaniel Hayward of the US, independently discovered that adding sulfur to raw rubber helped prevent the material from becoming sticky. Inventors were particularly interested in developing synthetic substitutes for those natural material that could be molded when heated. Natural rubber was sensitive to temperature, becoming sticky and smelly in hot weather and brittle in cold weather. Plastics vary immensely in heat tolerance, hardness, and resiliency. People have been using artificial organic polymers for centuries carpet fiber.
