In monkey prefrontal cortex (PFC), approximately 50% of the local axon terminals of pyramidal neurons form synapses with the dendritic shafts of GABA neurons. Subclasses of GABA neurons can be distinguished by the presence of different calcium-binding proteins. For example, in monkey PFC, parvalbumin (PV)-containing cells comprise approximately 25% of GABA neurons and are predominantly located ...

A mathematical model of a cracked rotor and an asymmetric rotor with two disks representing a turbine and a generator is uti­ lized to study the vibrations due to imbalance and side load. Nonlinearities typically related with a “breathing” crack are included using a Mayes steering function. Numerical simulations demonstrate how the variations of rotor parameters affect the vibration response an...

In addition to genomic pathways, estrogens may regulate gene expression by activating specific signal transduction pathways, such as that involving phosphatidylinositol 3-kinase (PI3-K) and the subsequent phosphorylation of Akt (protein kinase B). The Akt pathway regulates various cellular events, including the initiation of protein synthesis. Our previous studies showed that synaptogenesis in ...

The axle shaft is a component of the power transfer system which often experiences mechanical failure. purpose this study was to determine degree fatigue and hardness metal shafts with variations in frictional load as information on friction welding recommendations shafts. research method used experimental method, way compare specimens loads 2 kg, 4 6 kg using Rockwell testing rotary bending ma...

The process of excavating roadway, shafts, and exploiting coal seams located near the ground may cause subsidence surface, cracking, damage to structures on surface. Therefore, it is necessary rely specific conditions site calculate forecast level impact works when excavated ground. Based topographical conditions, geological hydrogeological current status technical design excavation twin inclin...

This article explores the heat and mass transfer behaviour of magnetohydrodynamic free convective flow past a permeable vertical rotating cone and a plate filled with gyrotactic microorganisms in the presence of nonlinear thermal radiation, thermo diffusion and diffusion thermo effects. We presented dual solutions for the flow over a rotating cone and a rotating flat plate cases. Similarity var...

This article deals with the dynamic properties of individual wheel electric powertrains for fully electric vehicles, characterised by an in-board location of the motor and transmission, connected to the wheel through half-shafts. Such a layout is applicable to

in many cases, a torsional shaft may be a thick-walled radially inhomogeneous cylindrical object. the hollow shafts made of functionally graded materials (fgms) are such kind of compositions which were studied in this paper. cylindrical fg shafts are composed of ceramic and metallic parts with power function distribution across the radial direction. the ceramic phase is isotropic elastic and th...
