In recent years, Reclaimed Asphalt Pavement (RAP) has become very popular in pavement construction due to its benefits the economy and environment. The present study investigates feasibility of employing Waste Cooking Oil (WCO) Engine (WEO) as rejuvenators blended with reusable asphalt binder through physical rheological properties at high intermediate temperatures. Examined conventional WCO-an...

Graphene Tourmaline Composite Micropowder (hereinafter referred to as GTCM) modified asphalt was prepared by the ball milling method. The effects of different temperatures and frequencies on high-temperature performance composite-modified were evaluated dynamic shear rheological test, viscoelastic properties under stresses analyzed. low-temperature GTCM-modified analyzed bending beam its mechan...

Deflection analysis of a simply supported microbeam subjected to a concentrated load at the middle is investigated on the basis of a shear deformable beam theory and non-classical theory. Effects of shear deformation and small size are taken into consideration by hyperbolic shear deformable beam theory and modified strain gradient theory, respectively. The governing differential equations and c...

steel shear walls, like bracings are a resistance system against wind and earthquake loads, which have more advantages than other systems. this paper is investigating the influence of openings on steel shear walls under increasing static loads. for this purpose, the experiments of other researchers on finite elements method have been checked and after investigating the correctness and precision...

in this research, using the modified compression field theory (mcft), a new truss based model is proposed to predict the behavior of reinforced concrete coupling beams with diagonal reinforcement. the model is able to consider the effects of shear and axial forces and bending moment, simultaneously. the proposed model includes a nonlinear shear spring, an axial spring, two inclined truss member...

Ultraviolet radiation is the main cause of degradation in asphalt pavement. To improve performance pavement used strong ultraviolet (UV) region western plateau, China, this study explores effects adding nano-montmorillonite and carbon black to SBS-modified asphalt. Through conventional index detection, dynamic shear rheological tests, low-temperature bending creep UV aging high- performance, fa...

sensorless speed torque control of induction machines has been widely used in many industrial applications. the simple method of direct vector control can provide tacholess control as well as more complex approaches. in this method, the motor flux can be obtained by measuring voltage and current and integrating motor back electromotive force. the only required motor parameter is stator resistan...

introduction: acinetobacter baumannii, a known causative agent of nosocomial infections, is one of the highly antibiotic-resistant gram-negative bacilli. carbapenem-resistant acinetobacter isolates are increasingly reported worldwide. carbapenems such as imipenem and meropenem are efficient antimicrobial agents commonly used for the treatment of infections caused by multi- resistant a. baumanni...
