Abstract Background Sarcopenia and sarcopenic obesity (SO) have a greater impact on the elderly. This study aimed to explore whether there were sex differences in prevalence adverse outcomes of sarcopenia SO community-dwelling elderly individuals East China. Methods was cross-sectional that enrolled 213 males 418 females aged > 65 years. Demographic characteristics, body composition, hand grip, gait speed, indices glucose lipid metabolism collected. diagnosed using Asian Working Group for...
Studies on carbon fiber (CF)/poly(ether ether ketone) (PEEK) hybrid textiles were initiated several decades ago because their flexibility and conformability make them a promising alternative to traditional prepregs. The adhesion between the CFs PEEK is mostly controlled by inherent surface properties mutual wettability. However, details of these remain largely unknown, especially those PEEK. Therefore, determine interfacial fibers, we performed comprehensive study characterized topography...
Abstract The application of carbon fiber reinforced polymer (CFRP) in aerospace, automotive and other fields is expanding rapidly due to its high strength‐to‐weight ratio excellent mechanical properties. However, the susceptibility delamination damage thickness direction still needs be addressed urgently. In this study, prepregs were combined with short‐cut aramid (SAFs) veils through hot compression molding produce SAFs‐interlaminar‐toughened (SAFs‐CFRP). effect areal density SAFs on...
As a promising alternative to traditional prepreg, carbon fiber/poly(ether ether ketone) (CF/PEEK) hybrid composites have attracted wide public interest for their flexibility and conformability. However, modification methods focused on the premix not been previously studied. In present work, interfacial strength of composite was improved by treating PEEK fibers together in radiofrequency (RF) plasma containing one following gases achieve surface activation: air, Ar, or Ar-air. After...
Particle swarm optimization (PSO), which is a new robust stochastic evolutionary computational algorithm based on the movement and intelligence of swarms, proposed to estimate parameters Bouc–Wen hysteresis model. The performance PSO method compared with more common genetic algorithms (GAs) in terms parameter accuracy. Simulation results model all unknown are illustrated show that higher quality solution better efficiency than GA can be achieved by means method. Furthermore, estimation noisy...
Dexmedetomidine (DEX) exhibits neuroprotective effects as a multifunctional agent in numerous neurological disorders. However, traumatic brain injury (TBI), the molecular mechanisms of these remain unclear. The present study investigated whether DEX, which has been reported to exert protective against TBI, could attenuate neuroinflammatory-induced apoptosis and clarified underlying mechanisms.A weight-drop model was established, DEX intraperitoneally injected 30 min after inducing TBI rats....
The design and development of thermal insulation materials is very important for the treatment offshore oil pipelines. Understanding energy transport in predicting their conductivities have theoretical practical value materials. In this work, lightweight thermally insulated (LWTI) composites with desired mechanical strength pipelines applications were prepared using epoxy resin (EP) as matrix hollow glass microspheres (HGMs) filler. morphology, density, properties HGM/EP LWTI studied first....
In this study, the curing kinetics of phenolic amine/epoxy resin system were investigated by nonisothermal differential scanning calorimetry (DSC). The model-free isoconversional method Ozawa-Flynn-Wall reveals a dependence Eα (activation energy) on conversion (α), which interprets autocatalytic reaction mechanism system.

Abstract Carbon fiber‐reinforced polymer composites (CFRPs) are widely used in many fields because of their excellent mechanical properties; however, they very sensitive to low velocity impact. A new‐type biomimetic structure, which has a “bricks‐and‐mortar” arrangement nacre from mollusk shells, was designed and manufactured for enhancing the impact resistance CFRPs. The response absorption energy this structure were also investigated. Impact damage forms analyzed based on surface internal...
Steel slag is the waste generated after steel smelting, which has cementitious activity. However, untreated can damage integrity of concrete due to its harmful expansion. This study prepared porous aggregates by mixing powdered slag, fly ash, and cement carbonated them with CO2 under high pressure conditions (0.2 MPa). The effect carbonation on performance aggregate was studied using volume stability crushing value. different products X-ray diffraction (XRD) thermogravimetric (TG) analyses,...
