The Ames Salmonella/microsome mutagenicity assay (Salmonella test; Ames test) is a short-term bacterial reverse mutation assay specifically designed to detect a wide range of chemical substances that can produce genetic damage that leads to gene mutations. The test employs several histidine dependent Salmonella strains each carrying different mutations in various genes in the histidine operon. ...
An agar plate method was developed for the performance of the IMVic (indole, methyl red, Voges-Proskauer, and citrate) tests in lieu of the conventional tubed liquid media. By modifying the composition of the media and adding agar, a single "X"-compartmented petri dish was prepared containing all four IMVic test media. Ease of performance and simplification of the test were achieved by inoculat...
Aeration effects on impact have been investigated by dropping a flat plate onto the water surface, in which the water is aerated to various degrees. An experimental study has been carried out in the newly commissioned Ocean Basin at Plymouth University’s COAST Lab. The falling block comprises a rigid impact plate connected to two driver plates and its total mass can be varied between 32 kg and ...
The purpose of this study was to clarify the influence of the palatal surface shape of dentures on food perception. Eighteen healthy dentulous subjects (mean age, 24 years • jwere investigated. Four types of experimental plate were used: i) a Tailor-made plate, ii) an Average-model plate, iii) a Smooth plate, and iv) a Wrinkle plate. Test foods consisted of Bavarian cream cubes containing 1-3 m...
Objective(s) The present study was undertaken to investigate the nociception activity of promethazine, a tranquillizer devoid of hypnotic activity in mice. Materials and Methods Antinociception was evaluated, using the acetic acid-induced writhing, tail flick, hot plate and formalin pain tests. Results Promethazine (4 and 6 mg/kg) and acetylsalicylic acid (100 mg/kg) produced a significant...
The modelling, simulation, fabrication and testing of a microchannel cooling plate are described in this article. The cooling component is to be used in microelectronic packaging applications. The nickelbased micro-channel cooling plate is fabricated on a glass substrate using a two-layer electroforming process borrowed from UV-LIGA. Forced convection of air or liquid is scheduled for this micr...
A new experimental set-up mounted at the muzzle of a singlestage gas gun has been designed in order to study fragmentation metallic rings under dynamic radial expansion. This concept takes advantage quasi-incompressibility HDPE whose flow plate impact-like loading is used apply pressure boundary condition ring’s inner surface. For configurations considered present work, average strain rate ring...
