externally bonded reinforcement on grooves (ebrog) is a new method that has been introduced to postpone or eliminate debonding of frp sheets from concrete surface in concrete beams strengthened for flexure and increase loading capacity. for strengthening reinforced conceret beams in strructure, use of different types of frp like: laminate, afrp, cfrp, and gfrp. by there is some differences betw...

Low skid resistance of road marking paint is one of the major issues in the safety of vehicle drivers, cyclists, and pedestrians when traveling on the city streets. Among the variety of marking paint, two-component paint is widely used at intersections and roundabouts. Therefore, the paint used should have adequate skid resistance. The object of this study was to evaluat...

Background: Obesity is associated with chronic inflammation in obese subjects, which leads to an increase of inflammatory cytokines. This study aimed to evaluate the effect of different intensity circuit resistance training on levels of interleukin 1 beta and interleukin-10 in obese men. Methods: In a semi-experimental trial during May to August 2020, 44 obese men from Tehran city were selecte...

The influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. The incorporation of nanoclay into epoxy enhances the impact resistance of the composites. The impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...

This study assesses the ballistic impact strength of thin plates made ultra-high-performance concrete (UHPC) with low cement content (250 kg/m3) and volumes 80% steel 20% polypropylene (PP) hybrid fibers. The were prepared thicknesses 30, 50, 70 mm fiber volume ratios 1.5% 3.0%. Compressive strength, flexural tensile residual determined using experimental methods. Test results showed that regar...
