background: use of contrast agents (cas) during ct simulation for treatment planing system leads to changes in  electron density. in this study we aimed to investigate the effect on  calculated dose of various concentrations of cas on treatment planing systems in different dose calculation algorithms. materials and methods: contrast agent (0.769 mg/ml iopromid) - water mixtures at concentration...

introduction: current thermal cycling units fail to simulate the drinking behaviors, and oral balancing temperature. they cannot also simulate other oral conditions such as drink coloring, and chemicals like tea, coffee, carbonated and noncarbonated, citrus juices as well as alcoholic and nonalcoholic drinks and also saliva and milk itself. the main objective of this study is to introduce the d...

© Deli Wang Laboratory at UCSD. Unit Overview This unit takes an approach to physics that differs markedly from much of what we have encountered in previous units. Rather than cataloging the elementary components of matter, we look at what happens at the macroscopic scale when the interactions of these components with one another and their environment lead to entirely new—emergent—behavior. Aft...

The Programmed Investigation Unit (P.I.U.) of the Manchester Royal Infirmary is an inpatient department providing facilities for all tests used in medicine. There are two special features of the unit: the timing of the admission of patients to suit their convenience; and placing of the tests in a compatible rapid sequence, which is incorporated in a timetable agreed with the investigative depar...
