Electrical cables of all types are subject to aggressive environments that can create defects or accelerate aging. Many application domains require diagnosis methods and tools. Among many methods, reflectometry has proven to be the best candidate and can be easily applied to the detection and localization of hard defects, while only requiring one access point to the wire. But soft defects are m...

Today’s cities face many challenges due to population growth, aging population, pedestrian and vehicular traffic congestion, water usage increase, increased electricity demands, crumbling physical infrastructure of buildings, roads, water sewage, power grid, and declining health care services [13], [14]. Moreover, major trends indicate the global urbanization of society, and the associated pres...

Li-ion batteries will lose both capacity and power over time due to calendar aging caused by slow parasitic processes that consume Li + ions. Studying mitigating these is traditionally an equally venture, which especially taxing for the validation of new active materials electrolyte additives. Here, we evaluate whether potentiostatic holds can be used accelerate diagnosis loss during aging. The...

The aged adaptive immune system is characterized by progressive dysfunction as well increased autoimmunity. This decline responsible for elevated susceptibility to infection and cancer, decreased vaccination efficacy. Recent evidence indicates that CD4+ T cell–intrinsic alteratins contribute chronic inflammation are sufficient accelerate an organism-wide aging phenotype, supporting the idea cel...

In order to remain competitive with respect to low-cost overseas markets, domestic moldmakers will have to increase the productivity of their engineers and maintain high quality standard, while dealing with the problem of an aging workforce. To increase the competitiveness of the European automotive industry, the concept of and Integrated Design and Engineering Environment (IDEE) has been devel...

Cognitive decline is a major deficit that arises with age in humans. While some research on the underlying causes of these problems can be done in humans, harnessing the strengths of small model systems, particularly those with well-studied longevity mutants, such as the nematode C. elegans, will accelerate progress. Here we review the approaches being used to study cognitive decline in model o...

The effect of abscisic acid on cotton (Gossypium hirsutum L. cv. Acala 4-42) and bean (Phaseolus vulgaris L. cv. Red Kidney) explants was 2-fold. It increased ethylene production from the explants, which was found to account for some of its ability to accelerate abscission. Absci is acid also increased the activity of cellulase. Increased synthesis of cellulase was not du to an increase in agin...

Aging is the process that the physiological functions necessary for survival and fertility of an organism are deteriorated. There are a variety of different mechanisms that are thought to participate in aging process. Recently, three papers show that wnt signaling pathway may also contribute to the aging. One molecular characteristic of senescence in human cells is the formation of SAHF, and th...

The tensile properties of fiber-reinforced composites (FRP) under various factors composite aging were studied by test. test parameters mainly include temperature, salt spray, ultraviolet, rainwater, and stress. results show that the higher faster FRP strength decreases; At same ultraviolet radiation has little effect on BFRP bars. Salt spray rainwater hydrolyze resin surface steel bars expose ...
