The article discusses the application of vibrational spectroscopy techniques for in vivo identification and characterization of glucose biomolecules monitored in the skin of healthy, prediabetes and diabetes subjects; for molecular characterization of water and proteins in in vivo monitored patch tested inflamed skin of the patients with contact dermatitis; for description of nucleic acids and ...

This paper is concerned with an investigation into the localized instability of a thin elastic orthotropic semi-infinite plate. In this study, a semi-infinite plate, simply supported on two edges and under different boundary conditions of clamped, hinged, sliding contact and free on the other edge, is studied. A mathematical model is used and a general solution is presented. The conditions unde...

We start with a three-dimensional equilibrium problem involving a linearly elastic solid at small strains subjected to unilateral contact conditions. The reference configuration of the solid is assumed to be a thin shallow shell with a uniform thickness. We focus on the limit when the thickness tends to zero, i.e. when the three-dimensional domain tends to a two-dimensional one. In the generic ...

Kinematics are widely used in computational processes as input parameters for displacement driven models. Small errors in kinematics can lead to compounded errors in final contact results hence accuracy is of utmost importance [1]. When using registration to acquire kinematics from images, for instance magnetic resonance imaging (MRI), the initial conditions from manual registration may potenti...

Dupin cyclides form a 9-dimensional set of surfaces which are, from the viewpoint of differential geometry, the simplest after planes and spheres. We prove here that, given three oriented contact conditions, there is in general no Dupin cyclide satisfying them, but if the contact conditions belongs to a codimension one subset, then there is a one-parameter family of solutions, which are all tan...

environment contamination by heavy metals is a major issue threatening human health. adsorption is one of the biological processes for removing toxic metals from wastewater. the aim of this study was to determine the rate of lead biosorption from industrial wastewater by spirulina platensis. this laboratory scale experimental study was performed during april 2014 to october 2014 in environmenta...

OBJECTIVES The aim was to analyze influential factors and effects of proximal contact loss between implant-supported fixed dental prostheses (FDP) and adjacent teeth. MATERIAL AND METHODS Ninety-four subjects treated with 135 FDPs supported by 188 implants were included. Degree of proximal contact tightness, food impaction, and periodontal/peri-implant tissue conditions were assessed in 191 p...

This paper presents mathematical conditions and algorithm for a whole arm manipulation planning with switching contact modes. The motion planning for such a system should consider changing the dynamics and kinematics according to contact modes. We show the conditions about kinematic and dynamics aspects to be satisfied for the motion planning. The conditions give the restriction of feasible con...

The relative sliding motion of two elastic bodies in contact induces wear process and contact shape evolution. The transient process tends to a steady state occuring at fixed contact stress and strain distribution. This state corresponds to the minimum of the wear dissipation power. The optimality conditions of the functional provide the contact stress distribution and the wear rate compatible ...
