Integrity and strength

Ma and Tomasko found that the structural integrity and strength of the polymer were unchanged. They also found that the contact angle and the wicking rate were indeed altered by the procedure. Their method has an advantage over previous work in that it is less disruptive of the polymer network and therefore the surfactant-polymer interactions can be more precisely investigated. However, such a method is only applicable to a limited number of materials because of the required solubility behavior. 

It was now possible to greatly reduce papers deterioration rate and to restore integrity and strength to those already damaged (1). Barrow s equipment and techniques for doing this have been acquired by more than thirty institutions, worldwide. 

Chu and co-workers at Cornell investigated the combination of PGA and Dacron. They produced knitted fabric grafts composed of PGA and Dacron fibers blended at various compositional ratios. They studied the properties of these bicomponent fabrics in vitro. Their major finding was the achievement of increasing water porosity over time without significant losses in the structural integrity and strength of the specimens. 

Experimental investigations have shown that voids, high temperature, and moisture affect interfacial bond strength and are detrimental to composite integrity and strength. As would be expected, the degrading effects of moisture are increased with increasing temperature ... 

These bimodal, interconnected membrane structures should be of significant commercial value, since the majority of filaments are nanofibers (providing, for example, ultra-efficient filtration properties) and the larger fibers are interconnected in such a way as to provide structural integrity and strength to the web. To our knowledge, however, the charge injection method has so... 

The most obvious role of calcium is to provide structural integrity and strength in bones and teeth. Approximately 99% of the total body calcium content is used for this purpose. Bone also serves as a reservoir of calcium that can be drawn upon when serum calcium concentrations decline. The remaining 1% of the body s calcium is contained in blood, extracellular space, muscle, and other tissues, in which calcium concentrations are kept relatively...
