The experimental and theoretical procedures used to gather ergonomic data and derive theoretical estimates of stability, effort, and safety in use of a curb-climbing aid for standard manual wheelchairs are presented. The aid, intended for use of paraplegic persons, employs ramps which the user while seated in the chair can deploy and retrieve using attached telescoping rods. Ramps and rods may ...

This study investigated the levels of adrenomedullin (AM) and the gene expression of AM, calcitonin receptor-like receptor (CRLR), receptor activity-modifying proteins (RAMPs), and receptor-coupling protein (RCP) in the testis, ventral prostate, seminal vesicle, and epididymis in rats aged 3, 12, and 20 months by radioimmunoassay and semiquantitative reverse transcription-polymerase chain react...

RAMPs (receptor activity-modifying proteins) are single-pass transmembrane proteins that associate with certain family-B GPCRs (G-protein-coupled receptors). Specifically for the CT (calcitonin) receptor-like receptor and the CT receptor, this results in profound changes in ligand binding and receptor pharmacology, allowing the generation of six distinct receptors with preferences for CGRP (CT ...

A real-life motorway in Belgium is studied and a comparison is made between a simulation of a morning rush hour situation without control and a simulation of a morning rush hour situation with ramp metering implemented. Two types of controllers are compared: a traditional ALINEA based controller and a model predictive control based ramp metering controller. In order to evaluate the controllers ...

A i2 inch square plastic bowl some 5 inches deep with sloping ramps has three strands of t inch copper tube fitted around the inside surface, the upper band about 1 inch below the rim, and each 1/16 inch apart A low voltage of 12 to 25 volts is applied to the tapes from a mains transformer or battery. Small animals are attracted up the ramps and into the bowl by a suitable bait; as they cross t...

We develop a standalone, real-time solar forecasting computational platform to predict one minute averaged solar irradiance ramps ten minutes in advance. This platform integrates cloud tracking techniques using a low-cost fisheye network camera and artificial neural network (ANN) algorithms, where the former is used to introduce exogenous inputs and the latter is used to predict solar irradianc...

Smoothly shaded color ramps, important for presentation graphics and computer imaging, are difficult for color managed systems utilizing device profiles. The causes for disruptive artifacts such as contours and banding are examined and a set of visual limits are established that, if met will avoid them. Based on these visual thresholds, an analysis of the numeric representation and processing o...

A simple two-atommodel is shown to describe a Bose-Einstein condensate of alkali atoms subjected to external magnetic field ramps near a Feshbach resonance. The implications uncovered for two atoms in a trap can be applied at least approximately to a many-atom condensate. A connection to observations is accomplished by scaling the trap frequency to achieve a density comparable to that of the ex...

This paper demonstrates the effectiveness of parametrically-upscaled continuum damage mechanics (PUCDM) models for multiscale analysis S-2 glass fiber/SC-15 epoxy matrix composite beams subjected to single-edge notched bending (SENB) tests. The SENB experiments with [012/9012] double-ply and [08/908/08] triple-ply use synchrotron X-ray phase-contrast imaging in-situ characterization. PUCDM repr...
