This paper develops a novel approach to microscale locomotion and manipulation using flagellated bacteria for actuation. We use a blotting procedure to attach flagellated bacteria to a buoyancy-neutral plate called a microbarge and deploy the plate in a microchannel . The motion of the plate depends on the propulsion of the bacteria which in turn depends on the distribution of the cells on the ...

This paper describes the estimation of the sound power radiated from a modified structure using an aluminum plate es asimple example. The modal parameters of the original, unmodified aluminum plate are first determined by the experimental modal analysis. Second, those of the modified aluminum plate are calculated by the Modal Synthesis Method. Using these obtained modal parameters, the three fa...

This study concerns the dynamic characteristics of a prestressed isotropic, rectangular plate continuously supported by an elastic foundation and carrying accelerating mass M. Closed form solutions of the governing fourth order partial differential equations with variable and singular coefficients are presented. For the twodimensional plate problem, the solution techniques is based on the doubl...

A new method for estimating the frequency of antigen-responsive T cells, using a cell proliferation assay, is described. In this assay, the uptake of tritiated thymidine by peripheral blood mononuclear cells which have been exposed to antigen, is measured for each well on a microtiter plate. Whereas this assay is generally used as part of a limiting dilution assay, here we estimate the frequenc...

This retrospective study compared clinical, radiological and subjective outcomes between patients with a distal radius fracture fixed with a variable angle or fixed angle volar locking plate. Radiological parameters were assessed between initial and final post-operative films. Post-operative clinical range of motion as a proportion of that in the opposite wrist was assessed clinically, and sati...

This paper describes the design and simulation by HFSS simulator of a probe-fed Planar Inverted-F Antenna (PIFA) for the use in PCS band [1850 MHz 1990 MHz]. A methodology based on parametric simulations (parameters are ground plan dimensions, height of radiating plate, feeding point position, shorting plate dimensions and positioning) was used to design optimized antenna. The simulation allowe...

Simultaneous heat and mass transfer in unsteady free convection flow with thermal radiation and thermal diffusion past an impulsively started infinite vertical porous plate subjected to a strong magnetic field is presented. The dimensionless governing equations for this investigation are solved analytically using two terms harmonic and non-harmonic functions. The influence of various parameters...

An accurate solution procedure based on the three-dimensional elasticity theory for the free vibration analysis of Functionally Graded Sandwich (FGS) plates is presented. Since no assumptions on stresses and displacements have been employed, it can be applied to the free vibration analysis of plates with arbitrary thickness. The two-constituent FGS plate consists of ceramic and metal graded thr...

Cet article rend compte des écarts entre les ambitions initiales d’un projet de recherche international visant le développement d’objets connectés pour l’accompagnement personnes vivant avec la maladie Parkinsons au cours sa mise en œuvre France. Nous y présentons composition du collectif hybride, ses objectifs et enjeux auxquels il est confronté. Les modalités prise savoirs expérientiels sont ...

Laboratory experiments have been performed to investigate photocatalytic detoxification by using TiO2 photocatalyst for treating dairy effluent. Various operational parameters such as catalyst concentration, initial concentration, angle of tilt of solar flat plate reactor and flow rate were investigated. Results indicated that the photocatalytic detoxification process can efficiently treat dair...
