Catheter Coils
Magnetic resonance imaging (MRI) is a very powerful tool for diagnostic imaging; however, it is very seldom used for guiding interventional procedures. On the other hand, in many procedures the quality of the guiding image modality is less than perfect, and therefore, MRI can be considered as an alternative. Among these interventional procedures, the percutaneous cardiovascular procedures have ...
متن کاملApplication of a Flame Dictionary Method in Turbulent Premixed Flame Modeling. Construction of a Flame Dictionary
|The construction of a ame dictionary of ame speeds and preheat thicknesses for a given reaction will be discussed. Once the entries of the dictionary have been established, they can be accessed by researchers and programmers to be used in diierent combustion applications. An application of the ame dictionary for turbulent combustion in a circular cylinder is given. Chemical reactions are often...
متن کاملInvestigation of Air Turbulence Intensity Effect on the Flame Structure in Different Flame Holder Geometry
In this paper, the effect of air turbulence intensity on the flame structure in various radii and lengths of a flame holder numerically studied. Finite volume method is used to solve the governing equations. The obtained numerical results using realizable k-ε and β-PDF models show a good agreement with the experimental data. The results show that flame holder with greater lengths yield shorter ...
متن کاملHybrid Intravascular Imaging Coils
E. Y. Wong, C. M. Hillenbrand, J. S. Lewin, J. L. Duerk Department of Biomedical Engineering, Case Western Reserve University, Cleveland, OH, United States, Department of Radiology, University Hospitals of Cleveland, Cleveland, OH, United States Introduction The use of MRI in minimally invasive, intravascular therapeutic procedures, has increased the need for imaging coils that provide accurate...
متن کاملα/β coiled coils
Coiled coils are the best-understood protein fold, as their backbone structure can uniquely be described by parametric equations. This level of understanding has allowed their manipulation in unprecedented detail. They do not seem a likely source of surprises, yet we describe here the unexpected formation of a new type of fiber by the simple insertion of two or six residues into the underlying ...
