Perfusion: DSC & DCE Basics & Analysis
The basic concept of a tracer-kinetic experiment dates back to the 1920's [1]: an indicator is injected rapidly in the blood stream and its concentration in the tissue of interest (mmol/ml tissue) is measured as a function of time. The precise shape and form of these curves depends on the manner in which the agent is injected, and on the properties of the tissue under consideration. If the inje...
متن کاملPerfusion : DSC & DCE Basics & Analysis
Introduction Perfusion is the term applied to capillary blood flow in tissue. Since the blood carries oxygen and nutrition to the tissue through the capillaries, perfusion is important in maintaining tissue viability. The study of brain perfusion has clinical applications due to the changes in perfusion associated with several neurological diseases. Diagnosis, lesion characterisation and follow...
متن کاملdegradation of oil impregnated paper insulation under influence of repetitive fast high voltage impulses
در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...
15 صفحه اولCharacterizing Protein/ligand Binding by DsC
All proteins are capable of recognizing and binding specific molecules such as other proteins, cofactors, prosthetic groups or drugs. Efforts to understand the mechanisms controlling selective binding were initially prompted by the realization that recognition and binding are universal features of all biochemical processes. These efforts have intensified with the awareness that knowledge-based ...
متن کاملDSC analysis of free-edged beams by an iteratively matched boundary method
This communication introduces a novel scheme for the treatment of free edge supports in the analysis of beams by using the discrete singular convolution (DSC) algorithm. Accommodating free edges has been a challenging issue in the DSC analysis of beams, plates, and shells. An iteratively matched boundary (IMB) method is proposed to overcome the difficulty. Numerical experiments are carried out ...
