This paper focuses on the analysis of an optimal control problem governed by a nonsmooth quasilinear partial differential equation that models stationary incompressible shear-thickening fluid. We start studying directional differentiability non-smooth term within state as prior step to demonstrate solution operator. Thereafter, we establish primal first order necessary optimality condition (Bou...

Abstract

Among the interesting studies published in this issue of the AABC that should be highlighted is the work on the primary and secondary thickening in the stem of a monocotyledon species by Marina B. Cattai and Nanuza L. de Menezes from the Instituto de Biociências of the Universidade de São Paulo. There is still great discussion over how this thickening occurs in this major group of flowering pla...

Bu çalışma, kayma ile kalınlaşan sıvılar (KKSler) işlem görmüş gelişmiş bıçak ve balistik dirençlere sahip aramid kumaş üretimine odaklanmaktadır. KKSler, PEG etil alkol içinde silika parçacıklarının homojenleştirilmesi, kurutma öğütme aşamaları hazırlanmıştır. Reolojik ölçümler, nanopartiküllerin PEG'e eklenmesinin, kalınlaşma davranışını arttığını göstermiştir. Silika konsantrasyonu arttıkça,...

When two fluids of different electrical conductivities are transported under the influence an electric field, electrokinetic instability (EKI) phenomenon often triggers in a microfluidic device once field strength and conductivity gradient exceed some critical values. This study presents detailed numerical investigation how rheological behavior fluid obeyed by non-Newtonian power-law constituti...

mal thickness of 41.1 μm, whereas sites treated with vehicle alone measured an average of 22.6 μm, indicating a significant difference in epidermal thickness between aTd-treated groups and vehicle controls, Po0.001 (Mann– Whitney test, Figure 1e and f). In summary, we have demonstrated in vivo capabilities of aTds to initiate protect and repair response in non-UVexposed guinea pig skin. By mimi...

Rheological characteristics of Al2O3, CuO and TiO2 nano particles were investigated in oil asthe base fluid at 1 and 2 wt.%. Constitutive relations for non-Newtonian fluid were discussedbased on the power-law model. Measured viscosities of each nanofluid were used to evaluatethe power-law and consistency index. Results indicated that the nanofluid viscosity decreasedby increasing the concentrat...

patients with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (melas) present with recurrent and partially reversible neurological deficits. lesions of melas classically cause a signal change in both the grey and white matter, predominantly in the occipital and parietal lobes. these lesions mimic infarction. here, we reported a case of melas with rare neuroimaging finding...

Dysphagia is the medical term for difficulty swallowing. Thickened liquids are often used in the management of dysphagia to improve bolus control and to help prevent aspiration. A range of starches and gums has historically been used to thicken liquids. Although thickened liquids improve swallow safety, they appear to have a great potential for unintended physiological consequences. Initial con...
