The impact of graphene reinforcement on the mechanical properties metals has been a subject intense investigation over last decade in surface applications to mitigate tribological loadings or for strengthening purposes when dispersed into bulk material. Here, effect plastic indentation response single layer grown copper is analyzed two configurations: one with at surface, other sandwiched under...

the effect of endogenous serotonin on long-term potentiation (ltp) in region cai was studied by blocking 5-ht2 receptors with ketanserin in rat hippocampal slices. such a block significantly en-hanced long-term potentiation of the cai population spike induced by high frequency stimulation of the schaffer collateral/ commissural pathway. this implies that serotonin acts on 5-ht2 receptors in cai...

early life events influence life-long patterns of emotionality and stress responsiveness and alter the rate of brain and body aging.  much research attention has focused on the programming effects of the hypothalamus pituitary axis (hpa) in early life and on understanding hpa function in response to stressors in adulthood. in comparison, there has been relatively little research on adolescence,...

Learning and memory require orchestrated regulation of both structural and functional synaptic plasticity in the hippocampus. While a neuropeptide alpha-melanocyte-stimulating hormone, α-MSH, has been implicated in memory acquisition and retention, the functional role of its cognate receptor, melanocortin-4 receptor (MC4R), in hippocampal-dependent synaptic plasticity has not been explored. In ...

This paper investigates shear behaviour of reinforced concrete using multi-surface plasticity model. analysis uses nonlinear finite element simulation 3D-NLFEA package. The experimental data adopted from the results test on eighteen beams where nine carried out by Bresler and Scordelis in 1963 similar Vecchio Shim 2004. constitutive model for material which used this is based plasticity-fractur...
