  • This engineer manual (EM) describes the inspection, evaluation, and repair of hydraulic steel structures, including preinspection identification of critical locations (such as fracture critical members and various connections) that require close examination. Nondestructive testing techniques that may be used during periodic inspections or detailed structural inspections are discussed. Guidance is provided on material testing to determine the chemistry, strength, ductility, hardness, and toughness of the base and weld metal....

  • After 40 the muscle fibbers shrink and replaced slowly with a tough fibrous tissue.Muscle changes often begin in the 40s in women. Lipofuscin (an age-related pigment) and fat are deposited in muscle tissue. This is most noticeable in the hands, which may appear thin and bony. Muscles may become rigid with age and may lose tone, even with regular exercise. Loss of muscle mass reduces strength which contributes to fatigue, weakness, and reduced activity tolerance. Exercise is one of the best ways to slow or prevent problems with the muscles, joints, and bones....

  • Fiber composite technology is based on taking advantage of the high strength and high stiffness of fibers, which are combined with matrix materials of similar/ dissimilar natures in various ways, creating inevitable interfaces. In fiber composites, both the fiber and the matrix retain their original physical and chemical identities, yet together they produce a combination of mechanical properties that cannot be achieved with either of the constituents acting alone, due to the presence of an interface between these two constituents.

  • Immune system is composed of innate and adaptive responses and plays critical roles in cancer development and destruction. A century ago, Paul Ehrlich postulated that cancer would be quite common in long-lived organisms if not for the protective effects of immunity. About 50 years later, Burnet and Thomas proposed the concept of cancer immunosurveillance based on the experimental evidence of immune recognition of tumor antigens expressed on tumor cells (Dunn et al. 2004 ) . In 1971, the US Congress created a National Cancer Act – a War on Cancer.
