Strain 2 D en miocardiopatía dilatada

Direct calculation of 2 D components of myocardial strain usingsinusoidal

A new technique to measure local planar strain in left ventricular myocardium using two-dimensional tagged MR images is presented. This new technique is computationally fast, is fully automated, and generates dense motion estimates. It is based on using a 1-1 SPAMM tag pattern which comprise several one-dimensional sinusoidal tag patterns at diierent frequencies. A local deformation of the myoc...

3-Hy­droxy-2-[(2E)-1-(2-hy­droxy-6-oxocyclo­hex-1-en-1-yl)-3-(2-meth­oxy­phen­yl)prop-2-en-1-yl]cyclo­hex-2-en-1-one

In the title compound, C(22)H(24)O(5), each of the cyclo-hexenone rings adopts a half-chair conformation. The hy-droxy and carbonyl O atoms face each other and are orientated to allow for the formation of the two intra-molecular O-H⋯O hydrogen bonds which are typical of xanthene derivatives. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into layers parallel to the ab...

EN 202 : Problem Set 2

Problem 1 Find u(x, y) satisfying u x + u y = u 2 , u(x, −x) = x, −∞ ≤ x ≤ ∞ Sketch the characteristic curves and show the domain of validity of the solution in the (x, y)-plane. In this problem we will examine the solution to a nonhomogeneous first-order PDE with constant coefficients. In order to solve this problem we can follow a typical approach: (1) find an explicit form for the characteri...
