Abstract Concrete is an indisputable material for the construction of various types of structures in the modern advancement of civil infrastructures. Concrete is strong in compression but weak in tension and shear. To eliminate those problems, the introduction of fiber was brought in as an alternative to developing concrete in view of enhancing its tensile and shears strength as well as improvi...

The Disposal of large quantity of plastic cover may cause pollution of land, water bodies and air. The proposed concrete which is made up by adding plastic in concrete may help to reuse the plastic cover as one of the constituents material of concrete, to improve the certain properties of concrete. The properties of concrete as varying percentages of plastic will test for compressive strength a...

Cryogenically cooled components in infrared instruments designed by Utah State University's Space Dynamics Laboratory traditionally have been mounted on glass-epoxy composite (G-10) cylinders for thermal isolation. Ensuring adequate mechanical stiffness to withstand typical launch loads often compromises the desired thermal isolation and conduction parasitic heat loads become a concern. Beginni...

The present work study flexural and tensile behavior of short Kenaf fiber reinforced composites. The fibers are chemically treated in 2% NaOH solution at room temperature. Short fibers of 4mm and 8 mm are used in the present work. The composite lamina is prepared by hand molding using isopthalic polyester resin. Flexural test and tension tests are carried out as per ASTM standards. The flexural...

Three different ways of shifting the pCa/tension curve on the pCa axis have been studied and related to changes in the rate constants of the cross-bridge cycle. The curve midpoint shifts to higher pCa's when the substrate (Mg-ATP) is reduced from 5 to 0.25 mM, when the phosphate concentration is reduced from 7.5 mM to 0, and when the ionic strength is reduced from 0.200 to 0.120. The Hill coeff...

Background: Tenderness, pain, muscle weakness, and limited range of motion (ROM) are symptoms of myofascial pain syndrome, which leads to restrictions on physical, occupational and social activities and ultimately reduction of productivity and quality of life. Different methods of rehabilitation are used to improve the symptoms of these patients. One of the new methods is the use of kinesio tap...

THE TIME THAT A MUSCLE IS UNDER TENSION DURING RESISTANCE STRENGTH TRAINING IS THOUGHT IMPORTANT IN MAXIMIZING THE HYPERTROPHIC RESPONSE OF SKELETAL MUSCLE. IMPLEMENTING STRETCHING IN BETWEEN SETS MAY INCREASE THE HYPERTROPHIC EFFECT BY ADDING TO TOTAL SESSION TIME UNDER TENSION AND AS SUCH INCREASE THE EFFECT OF VARIOUS NEUROMECHANICAL AND METABOLIC STIMULI THAT ARE THOUGHT IMPORTANT TO HYPERT...

OBJECTIVES To assess the effect of interfacial surface roughness on the flexure strength and fracture mode and origin utilizing an in-vitro assessment of the clinical failure conditions expected for all-ceramic crowns and the connector area of fixed partial dentures (FPDs) using bilayered ceramic specimens tested in bi-axial flexure. METHODS Sets of 20 bilayered composite discs, with core:den...

Load transfer and mechanical strength of reinforced polymers are fundamental to developing advanced composites. This paper demonstrates enhanced load transfer and mechanical strength due to synergistic effects in binary mixtures of nano-carbon/polymer composites. Different compositional mixtures (always 1 wt% total) of multi-wall carbon nanotubes (MWNTs) and single-layer graphene (SLG) were mix...

Phase equilibria of a square-well fluid in planar slit pores with varying slit width are investigated by applying the grand-canonical transition-matrix Monte Carlo (GC-TMMC) with the histogram-reweighting method. The wall-fluid interaction strength was varied from repulsive to attractive such that it is greater than the fluid-fluid interaction strength. The nature of the phase coexistence envel...
