Determination of fatigue life of the unidirectional GFRP/Al hybrid composite laminates

Abstract: This paper investigates the effects of loading rate and fiber orientation on the fatigue behavior of the unidirectional glass-fiber reinforced-plastic/aluminum (GFRP/Al) hybrid laminated (GLARE-2) plates. Fatigue tests were performed at three kinds of stress ratios (R = 0.3, 0.1, and −0.1) on specimens with different fiber orientations, θ = 0°, 15°, 30°, 45°, 60°, 75°, and 90°, in the GFRP layers. All the fatigue results to be presented in this article were obtained in repeated tension-tension and tension-compression at stress ratios of 0.3, 0.1, and −0.1, and the results were compared with each other. It has been shown that the specimens have the highest fatigue life in the fiber orientation direction at R = 0.3 loading rate. Also, it has been shown that the fatigue life of the specimens decreases as the loading rate decreases.

Multivalued elliptic operators with nonstandard growth

Abstract: Abstract The paper is devoted to the Dirichlet problem for monotone, in general multivalued, elliptic equations with nonstandard growth condition. The growth conditions are more general than the well-known p ⁢ ( x ) {p(x)} growth. Moreover, we allow the presence of the so-called Lavrentiev phenomenon. As consequence, at least two types of variational settings of Dirichlet problem are available. We prove results on the existence of solutions in both of these settings. Then we obtain several results on the convergence of certain types of approximate solutions to an exact solution.

Low Serum Level α-Synuclein and Tau Protein in Autism Spectrum Disorder Compared to Controls.

Abstract: α-Synuclein (α-syn) and tau proteins are thought to be related with the synaptic loss and cell death underlying several important neurodegenerative diseases. The aim of our study was to investigate serum α-syn and tau levels in autism. Serum levels of α-syn and tau were measured, and autism spectrum disorder (ASD) severity was assessed at admission using the Childhood Autism Rating Scale (CARS) total score. The mean CARS score of the autism group on admission was 47.91 points (SD: 5.97). The results indicated that the mean serum α-syn and serum tau levels were significantly (p
