Cyanide has gained historical notoriety as a poison used with intent to cause fatality. Its occurrence in industry is confined to a small number of uses in a relatively narrow range of industries, including the manufacture of Perspex and nylon and in electroplating. With proper controls in these settings, episodes of poisoning are extremely rare. However, because of the potential for a fatal ou...

The characteristics of a knemometer designed for accurate lower leg measurement in babies were assessed. Repeated measurement of a 100 mm Perspex rod gave a mean length of 99.993 mm and a mean SD of 0.058. When used to measure leg length, technical error of the measurement technique was 0.31 with a mean leg length of 98.49 mm (coefficient of variation 0.31%). Leg lengths measured at birth in 32...

This rotating oxygenator is of a design differing from other rotating oxygenators in that the large surface area necessary for filming blood at high rates of flow is obtained by using a small number of concentric drums rather than a large number of discs. This makes for simplicity of manufacture and ease of assembly. The design is such that it can be cast in plastic in three parts and mass prod...

To guarantee the reliability of densitometric data in clinical trials on pulmonary emphysema a quality control procedure is presented, to prevent that a measured progression in lung density could be reflected by a gradual change in the maintenance of the computed tomographic scanner. For that purpose, a foam phantom has been developed, which mimicks the densities of emphysematous lung tissue, f...

Many types of biliary fistula have been created for the study of biliary secretion in the experimental perspex block'-animal. Most of these interfere considerably with n6' 5/e r , normal physiological function, either by bypassing r the sphincter of Oddi, or more commonly by failing body to maintain the enterohepatic circulation of bile. of Thureborn (1963) has shown that interruption of the en...

Experimental study was conducted to determine the effect of velocity axial fan, outlet vent height, position, area, and aspect ratio (h/w) ventilated enclosure on convection heat transfer. Rectangular wooden having top front transparent wall made up Perspex for visualization, internal physical dimensions box were 200 mm × 400 mm. Inlet at bottom while vents side wall. Electrically heated cylind...

It has been shown that radiochromic film is an ideal dosimeter for assessment and verification of delivered dose to irradiated blood products. Using a parallel opposing two-field technique on a medical linear accelerator, blood is irradiated to diminish the risk of transfusion-associated graft vs. host disease (TA-GVHD). The blood products are irradiated in a Perspex blood box to an applied dos...

The hydrodynamic behaviour of the spouted bed has been studied by considering the different system parameters (viz. static bed height, spout diameter, particle size, gas velocity and particle density). Experiments were carried out using a Perspex column of 4 inch diameter. Attempts have been taken to develop correlations for the bed expansion / fluctuation ratios by varying different system par...

A LIXI(Light Intensifier X-ray Image) device has been employed in a real-time neutron radiography system. The LIXI is coupled to a video camera and the real-time images can be observed in a TV monitor, and processed in a computer. In order to get the real-time system operational, the neutron radiography facility installed at the IEA-R1m nuclear research reactor of the IPEN-CNEN/SP has been opti...

Most techniques at present in use for the Wassermann reaction require a great deal of bench and water bath space, are very time consuming, and put a considerable burden on those responsible for the preparation of glassware. The use of moulded perspex plates (M.R.C. pattern)* in this laboratory has cut down immensely the space and labour involved in doing routine Wassermann reactions, and has ad...
