Biaxial mechanical properties of the natural and glutaraldehyde treated aortic valve cusp--Part I: Experimental results.
To date, there are no constitutive models for either the natural or bioprosthetic aortic valve (AV), in part due to experimental complications related to the AV's small size and heterogeneous fibrous structure. In this study, we developed specialized biaxial testing techniques for the AV cusp, including a method to determine the local structure-strain relationship to assess the effects of bound...
متن کاملFull Adder Circuit . Part I
A set is pair if: (Def.1) There exist sets x, y such that it = 〈x, y〉. Let us mention that every set which is pair is also non empty. Let x, y be sets. Observe that 〈x, y〉 is pair. Let us mention that there exists a set which is pair and there exists a set which is non pair. Let us observe that every natural number is non pair. A set has a pair if: (Def.2) There exists a pair set x such that x ...

We introduce I1 has no pairs as an antonym of I1 has a pair. Observe that every set which is empty has also no pairs. Let x be a non pair set. Observe that {x} has no pairs. Let y be a non pair set. Note that {x,y} has no pairs. Let z be a non pair set. One can verify that {x,y,z} has no pairs. Let us observe that there exists a non empty set which has no pairs. Let X , Y be sets with no pairs....
متن کاملMechanical seals: some developments in face materials
Carbon has been used as a face material in mechanical seals for well over fifty years. The first grades of carbon used were developed from carbon electrical brush materials, but the continuous increase in the severity of mechanical seal operating conditions has necessitated ever improving grades of carbon. This paper details some of the means available to the carbon technologist to achieve thes...
متن کاملUltrasonic Nondestructive Testing Method for Evaluation of Annular Seals
Drilling boreholes is common practice in geotechnical and geoenvironmental investigations and in various other ex ploration, testing, and monitoring appli cations. When a casing is placed in a borehole an annular space is created be tween the casing and the surrounding soil. If not properly sealed, this annular space can be a potential path for trans port of contaminants in the subsurface e...
