This paper presents the results of a statistically designed experiment with eight all-refrigerator cabinets. The cabinets were designed with a view to be identical except for the fact that each cabinet was fitted with a specific non-adiabatic capillary arrangement. These cabinets were tested to the New Zealand test standard (NZS 6205.2) at 32°C ambient temperature and then the tests were repeat...

The electronic densities of states of atomically resolved single-walled carbon nanotubes have been investigated using scanning tunneling microscopy. Peaks in the density of states due to the one-dimensional nanotube band structure have been characterized and compared with tight-binding calculations. In addition, tunneling spectroscopy measurements recorded along the axis of an atomically resolv...

A flow injection system for the determination of selenium by electrochemical hydride generation and quartz tube atomic absorption spectrometry is described. The generator consists of an electrolytic flow-through cell with a concentric arrangement and a packed cathode made of particulated lead. The influences of sample flow rate, carrier gas flow rate and electrolysis current on the hydrogen sel...

objective the purpose of this study was to assess the frequency of complications of endotracheal intubation (eti) in neonates. methods the newborns that were admitted and needed urgent or semi-urgent intubation were enrolled in this study over a 1 year period. route for intubation in all cases were orotracheal. cases were not routinely sedated or paralyzed. the patients were clinically and radi...

background and purpose: inserting a nasogastric tube, though a common clinical procedure with widespread use for critically ill patients, can produce unexpected complications so that tube misplacement into the lungs is a potential complication with serious consequences. the reliability of common bedside methods to differentiate between pulmonary and gastric placement has not been acceptable. th...

Topological drawings are natural representations of graphs in the plane, where vertices are represented by points, and edges by curves connecting the points. Topological drawings of complete graphs and of complete bipartite graphs have been studied extensively in the context of crossing number problems. We consider a natural class of simple topological drawings of complete bipartite graphs, in ...

Computer simulation of mass distribution within the model and Fourier transforms of images depicting mass distribution are explored for verification of two alternative modes of the myosin molecule arrangement within the vertebrate skeletal muscle thick filaments. The model well depicting the complete bipolar structure of the thick filament and revealing a true threefold-rotational symmetry is a...

The solidification process in a multi-tube latent heat energy system is affected by the natural convection and arrangement of exchanger tubes, which changes buoyancy effect as well. In current work, tubes was examined during with focus on effects inside phase change material (PCM). behavior numerically analyzed using liquid fraction released, well temperature, velocity streamline profiles for d...

A good design of the ice rink floor could save a great deal capital and operational costs for hockey arenas. This focuses on cost-effective tube arrangement an optimal concrete coverage over tubes that provide sufficient heat transfer rate between coolant freezing ice. paper reports theoretical model to simulate characteristic different diameter, spacing distance, thickness rink. In addition, c...
