measuring and comparing grip and pinch strengths with their normative data is a valid method to detect intensity of the numerous damages of hand. this research was carried out with the aim of establishing normative data of grip strength and three types of pinch strengths (tip, key and palmar) in healthy iranian adults.in this cross-sectional study, the study population was formed of 1008 people...

The problem of calibrating parametric sonar systems at low difference frequencies used in backscattering applications is addressed. A particular parametric sonar is considered: the Simrad TOPAS PS18 Parametric Sub-bottom Profiler. This generates difference-frequency signals in the band 0.5-6 kHz. A standard target is specified according to optimization conditions based on maximizing the target ...

Capacity design procedure for the earthquake-resistant reinforced concrete (RC) structures is effective when actual member capacities do not greatly exceed the assumed design capacities. Moreover, RC members are expected to undergo large inelastic deformations for adequate seismic energy dissipation. Since flexural capacity and post-yield behavior of an RC member is largely controlled by steel ...

Background: The use of Glass ionomer cements (GIC) as restorative materials is beneficial due to fluoride release and ease of application. Strength and solubility are important properties that can affect the longevity of restorative materials in the oral environment. Aim: The objective of this study was to evaluate compressive, diametral tensile strength and solubility of a nanofilled GIC (Keta...

The article investigates the possibilities of obtaining high–quality expanded clay based on Gurlen deposit Republic Uzbekistan, with additives from local oil and fat combines – gossypol pitch dune sand Tuprakkala massif. It is determined that addition to raw mixture within specified limits significantly increases swelling mass. was also mass (together pitch) in moderate quantities contributes a...
