reliable characterization of subsurface soil in urban areas is a major concern in geotechnical and geological engineering projects. in this regard, this research deals with development of a 3d geological engineering model on mashhad city soil using sequential gaussian simulation (sgs) approach. the intense variability of soil in the study area has sometimes caused serious problems in civil engi...

Life history plasticity can be a strong predictor of the establishment and invasion success introduced fishes. Here, life-history traits four P. parva populations in adjacent ponds Southern England were measured throughout 2013 to determine timing length their reproductive season extent trait plasticity. The relative abundance (as catch per unit effort) was similar, with low variability relatin...

Reelin is an extracellular matrix neuroprotein which plays important roles during development and maturation of cerebellum. In the postnatal cerebellum, Reelin is synthesized by cerebellar granule cells and secreted to extracellular matrix. This secreted protein modulates adult synaptic function, neurotransmitter release and regulates plasticity. Exercise has beneficial effects on central nervo...

Introduction: The primary somatosensory cortex has an important role in nociceptive sensory-discriminative processing. Altered peripheral inputs produced by deafferentation or by long-term changes in levels of afferent stimulation can result in plasticity of cortex. Capsaicin-induced depletion of C-fiber afferents results in plasticity of the somatosensory system. Plasticity includes short-term...

finite cell method, are employed to compute a series of benchmark problems in the finite strain von Mises or J2 theory of plasticity. The hierarchical (integrated Legendre) shape functions are used for the finite element approximation of incompressible plastic dominated deformations occurring in the finite strain plasticity of ductile metals. The computational examples include the necking under...

This examination explains the utilization of bio-polymer powder for clayey soil enhancement. The article concentrates around examining strength attitude soils built up with homogenous bio-polymer. Carboxy methyl cellulose was determined as material to build normal soft soil. biopolymer has been added two separated rates (0.5 and 3%) by total weight Different tests were carried out consider impa...

Stomata are crucial in land plant productivity and survival. In general, with lower irradiance, stomatal and epidermal cell frequency per unit leaf area decreases, whereas guard-cell length or width increases. Nevertheless, the stomatal index is accepted as remaining constant. The aim of this paper to study the influence of ordinary epidermal cells and stomata on leaf plasticity and the influen...

The basal ganglia is a brain region critically involved in reinforcement learning and motor control. Synaptic plasticity in the striatum of the basal ganglia is a cellular mechanism implicated in learning and neuronal information processing. Therefore, understanding how different spatio-temporal patterns of synaptic input select for different types of plasticity is key to understanding learning...
