Colon carcinoma metastases with extension to chest wall and pericardium
Management of locally advanced colon cancer metastases is challenging and operation carries an increased risk of morbidity and mortality. The knowledge of exact sites of involvement can aid the surgeon to make a decision regarding complete resection or palliative therapy. PET/CT scan is an advantage in this setting because metabolic alterations often precede the anatomic changes; moreover, it c...
متن کاملVentricular extension into the abdominal wall.
In a previous paper mention was made of a girl with cyanotic congenital heart disease and a pulsatile tumour under the umbilicus (Astley and Parsons, 1953). This child died in Birmingham Children's Hospital in 1950, but the condition was thought to be a chance monstrosity until 1952, when Dr. Helen Taussig referred in a letter to another example of this condition. In 1955 both Dr. Catherine Nei...
متن کاملComputational Hydraulics
The aim is to give an understanding of the numerical approximation and solution of physical systems, especially in open channel hydraulics, but with more general application in hydraulics and fluid mechanics generally. The marriage of hydraulics and computations has not always been happy, and often unnecessarily complicated methods have been developed and used, when a little more computational ...
متن کاملLeaf hydraulics.
Leaves are extraordinarily variable in form, longevity, venation architecture, and capacity for photosynthetic gas exchange. Much of this diversity is linked with water transport capacity. The pathways through the leaf constitute a substantial (>or=30%) part of the resistance to water flow through plants, and thus influence rates of transpiration and photosynthesis. Leaf hydraulic conductance (...
متن کاملThe Tutte polynomial of a ported matroid
Las Vergnas’ generalizations of the Tutte polynomial are studied as follows. The theory of Tutte-Grothendieck matroid invariantsfis modified so the Tutte decomposition ,f(M) =f(M\e) +f( M/e) is applied only when e $ P (and e is neither a loop nor an isthmus) where P is a distinguished set of points called ports. The resulting “P-ported” Tutte polynomial tp has variables I, w; q,, qZ, . . . . qm...
