The International Organization for Standardization Technical Committee Metallic Materials—Tensile Testing stated in 2011 that temperature and strain rate variations would induce a change the results of tensile tests, termed as measurement uncertainty mechanical properties metals. means testing specimen at are not original possessed prior to testing. Hence, since time Galileo have been incorrect...

The spinning limit for three different fibres (cotton, viscose rayon and polyester) on a Dref-3 friction spinning machine has been investigated. The change in yarn properties with progressive change in count has also been reported. The count range has been seen to be dependent on fibre type. As one progresses from very coarse to fine counts, the yarn tensile property remain fairly unaltered for...

Thermoplastic polyurethanes (TPUs) are a class of thermoplastic elastomers (TPEs) that are used in a variety of applications (1). TPUs exhibit low temperature flexibility, excellent abrasion resistance, high tensile strength and good processing characteristics. The current medical grade TPU’s have unique property that the flex modulus decreases (softens) when placed in the body. A new resilient...

In Brief Hydration, the absorption of uid into the interstitial areas of a glove once it is wetted, adversely aaects the clinical performance of natural rubber latex gloves. These eeects potentially include increased conductivity, c hanges in tensile and tactile properties, and increased chemical and viral permeability. All of our data indicate that signiicant h ydration is an undesirable prope...

statement of problem: the bond strength of root canal sealers to gutta-percha seems to be an important property for maintaining the integrity of the apical seal which can result in reducing apical microleakage. purpose: the purpose of the present study was to compare the tensile bond strengths of four types of root canal sealers to gutta–percha. this study measured the maximum forces needed to ...
