During the manufacturing process, fibrous materials used in composite reinforcements are subjected to many sources of damage that must be managed if best possible quality is reached for final product. More specifically, carbon fibers subjected, during reinforcement manufacturing, friction with mechanical components and other tows excessive tensile loads due specific configurations required by t...

If we think of the graph as modeling a network, the vulnerability measure the resistance of the network to disruption of operation after the failure of certain stations or communication links. Many graph theoretical parameters have been used to describe the vulnerability of communication networks, including connectivity, integrity, toughness, binding number and tenacity.In this paper we discuss...

Selection of cotton fibers in terms their quality value has created a domain emerging interest among the researchers. In this study, newly developed Best-Worst Method (BWM) was integrated with Revised Analytic Hierarchy Process (RAHP) to rank fiber lots on basis six apposite properties namely bundle tenacity, elongation, micronaire, upper half mean length, uniformity index, and short index. Ran...

nowadays, polymer blends usages increase more and more in order to produce materials with better properties. according to many research works, the blends of polyolefins have shown industrial importance. the purpose of this project was to carry out some investigations on fibers melt spun from the polypropylene and low density polyethylene blends. pp and ldpe are immiscible. pp/ldpe blend filamen...

Since 1839, Yale medical students have been writing theses as part of their professional training. It is an introduction to the practice of original research, a demanding and sometimes exhausting pursuit. The thesis project promotes a tenacity well suited for the practice of medicine. The thesis advisor has a challenging role as well — one that can only be filled by an individual whose dedicati...

The absence of psychological complexes, tenacity in following the path I reputed to be right, and the habit of underestimating obstacles--a trait I inherited from my father-have helped me enormously in facing life's most tragic occurrences. To my father, and to my mother, I owe also a tendency to look on others with sympathy and without diffidence. This attitude, which was common to all four of...
