Abstract A novel manufacturing tool called sandwich flexible elastic grinding wheel is developed to achieve high material removal rates and machined finish of a mould steel. This made aluminium matrix, ethylene propylene rubber layer abrasive layer. Ethylene has great elasticity produces deformation when contacting with the workpiece. With existence an layer, rigidity at small scales allows occ...

The x-ray radiation shielding requirements beyond the first optics enclosure have been considered for the beam transport of the 2-ID-B and 2-ID-C branch lines of Sector 2 (SRI-CAT) of the APS. The first three optical components (mirrors) of the 2-ID-B branch are contained within the shielded first optics enclosure. Calculations indicate that scattering of the primary synchrotron beam by beamlin...

The consistency of different instruments and methods for measuring two-dimensional (2D) power spectral density (PSD) distributions are investigated. The instruments are an interferometric microscope, an atomic force microscope (AFM) and the X-ray Reflectivity and Scattering experimental facility, all available at Lawrence Berkeley National Laboratory. The measurements were performed with a gold...

A novel, self-terminating electrochemical etch process is proposed for the fabrication of scanning steel micro-mirrors. The process uses single mask photolithography, and the etching step is terminated automatically, which at the same time enables the depth profile shaping of the fabricated structure. The proposed process is characterized and then used to fabricate two versions of one-dimension...

The Centre for Sustainable Energy Systems at the Australian National University is working on the development of low cost durable mirrors for large paraboloidal dish concentrators and for smaller trough concentrators photovoltaic systems. Both concepts utilize a robust Glass on Metal Laminate (GOML) technology for the mirror surface. The dish mirror panels use the GOML material in a sandwich co...

This work reports on the influence of β-lactoglobuline (β-LGB) and of its denaturation on the adherence of quartz particles, taken as a model of particulate soil, on stainless steel AISI 304 with mirror finish. The substrate was soiled with quartz suspensions in water or in β-LGB solutions as such or previously heated at 75°C, and dried at room temperature or in an oven at 75°C. Cleanability wa...

Background: Stroke is one of the major causes of disability. Therefore, it is important to introduce and develop new treatment approaches in order to improve and enhance post stroke recovery process for medical, social and economical purposes. Aim: To determine the effect of mirror therapy on motor ability of patients with stroke. Methods: This Randomized Controlled Trial was conducted on 38 pa...

Objectives: Hand function is critical for daily life and work, especially with the use of electronic devices. This study determined the effect of mirror therapy in individuals with asymmetrical hand function. Method: Forty-two men with asymmetrical hand function were recruited. All participants were randomly divided into two groups: sham control (n = 21) and mirror therapy (n = 21). Both group...
