This book was released on 2009 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this work was to study the potential for contrast-enhanced functional ultrasound imaging (Cefui) to assess the abdominal microcirculation, according to three major axes of research: 1) The first axis consisted in proposing and validating a new method improving non invasive contrast-enhanced renal blood flow measurements, using the mean signal intensity in a feeding artery in order to normalize contrast-enhanced renal blood flow estimation. However, while these ex vivo results suggest that this technique has great potentials, other parameters, mainly ultrasound beam attenuation, must be taken into account to obtain reproducible measurements. 2) The second axis consisted in evaluating qualitative abdominal Cefui for tumoral detection. For the detection of liver metastases from carcinoid tumor, the first study reports sensitivity values for contrast-enhanced ultrasound similar to those obtained with enhanced computed tomography. The second study demonstrates that Cefui provides high specificity and predictive values for the early detection of residual tumor after radiofrequency ablation of renal tumors even though its sensitivity remains lower than that of contrast-enhanced CT. 3) The third axis deals with added diagnostic value in terms of characterization of renal tumors of quantitative assessment of tumor perfusion compared to that of qualitative analysis. Abdominal Cefui has unique advantages including low cost, availability, absence of renal toxicity and radiation, and excellent temporal resolution. However, it still requires improvements and standardization to be reproducible and be transferred to the clinical setting. It may somehow yield quantitative information with respect to abdominal organs microcirculation. Further studies correlating Cefui results with those of other functional imaging methods are needed

Download or read book Minimum competence in scientific English written by Sue Blattes and published by L'Editeur : EDP Sciences. This book was released on 2003 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage, devenu célèbre sous son sigle MCSE, a déjà été utilisé par plus de 50 000 étudiants, chercheurs, professionnels. L'objectif est de lire et écrire des textes en anglais scientifique avec facilité et pertinence. L'ouvrage est conçu pour que l'apprenant devienne un véritable utilisateur de l'anglais. La méthode originale repose sur l'analyse des fonctions et structures nécessaires : measurement, frequency, comparison, modification, link words, time, cause and consequence, hypothesis, modality, purpose and process, impersonal forms, compound nouns and adjectives. Dans chaque unit, des tests d'auto-évaluation permettent de se situer et de construire son parcours de formation, d'abord en définissant ses objectifs à l'aide des key points et du lexis, puis, de façon plus personnalisée, en puisant dans les examples in context, checkpoints (back to basics, word web), web search, FAQs... MCSE est l'outil de base d'une méthode qui comprend aussi d'autres outils dans la même collection (Listening Comprehension for Scientiflc English et Speaking Skills in Scientitic English). L'ouvrage est destiné à tout apprenant de niveau baccalauréat qui désire acquérir une réelle compétence dans l'écriture et la lecture de textes en anglais scientifique.
Download or read book An Introduction to Differential Manifolds written by Jacques Lafontaine and published by Springer. This book was released on 2015-07-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.
