  • 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....

  • Interfacial strength is one of important factors to affect working stability of structures and devices. In order to avoid interfacial cracking, an improved method based on the conventional one is proposed to establish the interfacial toughness function (or the set of the interfacial fracture criteria in mixed-mode loading). By preliminarily analyzing the Brazil nut specimen, the placements of applied load, where pure modes I and II occurred, were determined.

  • In this study, two types of acrylic latexes, PA (polyacrylate) and PU/PA (polyurethane modified PA), are investigated in their influences on mechanical properties of mortar under different interaction mechanisms. In light of a previous study, the polymer–cement hydrates interaction mechanisms in PA and PU/PA modified mortars are illustrated respectively, and the microstructures are simulated using a computer model.

  • Polymer modified alkali treated jute fibre as a reinforcing agent, substantially improves the physical and mechanical properties of cement mortar with a mix design cement:sand:fibre:water::1:3:0.01:0.6. The workability of the mortar is found to increase systematically from 155 ± 5 mm (control mortar) to 167 ± 8 mm (0.2050% polymer modified mortar). The density of the mortar is increased from 2092 kg/ m3 to 2136 kg/m3 with a concomitant reduction of both water absorption and apparent porosity. Optimal polymer content in emulsion (0.

  • 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.

  • In this study, the impact response of glass/epoxy laminates interleaved by Polycaprolactone (PCL) nanofibers is considered. PCL is a thermoplastic polymer, which is a good choice for toughening epoxy-based composite. The impact tests were conducted on curved laminates and under 24 and 36J.

  • 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.

  • Based on the increase in tensile strength and toughness (43% and 30%, respectively), the feasibility of the hybrid nanofibers containing Single-walled carbon nanotubes and Nylon 66 on reinforcing cementitious materials has been clarified. The well-linking effect of nanofibers in the microstructure of hardened cement pastes has been found by scanning electron microscope (SEM) analysis and well-explained for the increase in mechanical strengths. Besides, field emission transmission electron microscope (FE-TEM) analysis has also been conducted to analyze the properties of the hybrid nanofibers.
