Original scientific papers Performance of ultrasonic pulse velocity (UPV) in hydraulically bound mixtures is examined as a non-destructive testing, in order to estimate its potential for pavement material characterization. Test results show that an increase in cement content results in an increase in UPV values. Increase in steel slag aggregate content results in a decrease in UPV values. Analy...

The stages were: gathering information; 2) planning; 3) developing product; 4) validating. results this study indicate that all aspects assessment obtain good results. According to material experts, Moti...

Previous research has linked personality traits, material values, and money management to savings, debt, and compulsive buying. To extend previous research, four online surveys examined the Big Five personality traits and material values of those who manage their money and determined the independent effects of money management on wealth, debt, and compulsive buying. Results suggest that (a) ind...

BACKGROUND A new reference material for the liver enzyme aspartate transaminase (AST) (L-aspartate: 2-oxoglutarate-aminotransferase, EC 2.6.1.1), also called aspartate aminotransferase (ASAT), has been developed under the code ERM-AD457/IFCC. This certified reference material (CRM) for AST has been produced from a human type recombinant AST expressed in Escherichia coli and a buffer containing ...

Porcine aortic valve leaflets are comprised of three layers, each of which has a different composition and consequently, different mechanical properties. Each layer exhibits non-linear stress-strain behaviour and is modelled using a hyperelastic material model. Our objective is to determine the mechanical properties of each layer from experimental force-indentation depth data, ensuring that the...

immediate restoration after vital pulp therapy is essential in order to create and maintain effective coronal seal.the aim of this study was to evaluate the shear bond strength of recently used pulp capping materials: white mineral trioxide aggregate (mta), and calcium enriched mixture cement (cem) to composite resin with the use of etch-and-rinse and self-etch adhesive systems and compare them...
