Background: An MRI is potentially hazardous for patients with retained ferromagnetic bullets. Recent studies have aimed to develop dual-energy computed tomography (DECT) as a screening tool recognising highly Inconsistent findings been ascribed inherent CT technology differences. Previous research demonstrated significant Hounsfield unit (HU) measurement variation among single-source machines. ...

Rehabilitation therapy is the process to reduce the impairments and disabilities of upper or lower limb that are caused by accidents or stroke. This paper presents the design and development of a new hand rehabilitation device based on iris mechanism with basic Arduino coding to train the flexion and extension of the hand. The iris mechanism is designed using SolidWorks 2015 and the prototype i...

The DAVID is a transparent, multi-wire transmission-style detector that attaches to a linear accelerator (linac) collimator for use as an in vivo detector. Currently, the normal method for using the DAVID is to measure a signal at the time of phantom-based pretreatment verification and use that signal as a baseline to compare with in vivo measurements for subsequent treatment fractions. The dev...

The potential applications of ice-templating porous materials are constantly expanding, especially as scaffolds for tissue engineering. Ice-templating, a process utilizing ice nucleation and growth within an aqueous solution, consists of a cooling stage (before ice nucleation) and a freezing stage (during ice formation). While heat release during cooling can change scaffold isotropy, the freezi...

Pulsed laser light when of low to moderate intensity impinged into an aqueous media generates stress waves by thermoelastic mechanism. Referred to as photo-acoustic emission (PAE) these arise from sources during rapid laser liquid interaction that contains valuable information on the state of the composition and concentration of the liquid. Optical energy from a Q-switched Nd-YAG laser light so...

The UCLH Mark 1b is a portable EIT system that can address up to 64 electrodes, which has been designed for imaging brain function with scalp electrodes. It employs a single impedance-measuring circuit and multiplexer so that electrode combinations may be addressed flexibly using software. It operates in the relatively low frequency band between 225 Hz and 77 kHz, as lower frequencies produce l...

Gene-targeted mice lacking the AMPA receptor subunit glutamate receptor-A (GluR-A or GluR1) and mice with cytotoxic hippocampal lesions were compared with wild-type and sham-operated controls, respectively, on a conditional learning task using an elevated T-maze. Floor inserts (white perspex vs wire mesh) provided a conditional cue indicating in which goal arm a food reward was to be found. The...

The new geometrical design of stand-pipe air distributor for the combustion of the municipal solid waste was presented. The new design of the air distributors enables penetration of incombustible and unburnt carbon through opening between the air distributors, thus providing easy maintenance work. The fluidized bed experimental rig was constructed using Perspex column in which air was supplied ...

LCT consists of pliable latex sheets impregnated with cholestrol crystals which respond to different temperatures by emitting different wavelengths of light ranging from brown (cool) through yellow and green to blue (hot). These latex sheets form one wall of a sealed box with the opposite wall being made of perspex to allow the thermographic image to be viewed. The thermographic detectors are c...

The technique employed from 1949-1956, which has been described by one of us (Scott, 1952), was a slight modification of the method originally proposed by Rose, Ragan, Pearce, and Lipman (1948). Since 1956, a further modification has been employed, as suggested by Greenbury (1957), using Perspex trays (M.R.C. pattern) in place of tubes and racks. This method will be described in detail elsewher...
