In their most general forms imaging problems are severely ill-posed and nonlinear. These are the main obstacles to find non-iterative reconstruction algorithms. In this chapter we use structural information about the profile of the material property in order to determine specific features about them with a satisfactory resolution.

It has been shown that extracellular fluid volume expansion (ECVE) produces natriuresis (1,2) and phosphaturia (3,4,5) due to a decrease in the renal tubular reabsorption of these ions (3,4,5,6). However the biological signals for this phenomenon are as yet not elucidated.

The Chemical Educator, 2004
Volume-expansion work involves a pressure term. The treatment of this pressure term in chemistry texts is not uniform and likely to be misleading. It is shown that the definition of volume-expansion work in mechanics leads to the choice of the surface pressure as the required pressure.

The use of volume expansion in preterm infants
Paediatric and Perinatal Epidemiology, 2004SummaryThere is no consensus of opinion regarding the appropriate use of volume expansion in the sick preterm infant. Recent evidence suggests that excessive volume expansion may increase mortality in this group. We determined the use of volume expansion in non‐surgical preterm infants (<30 weeks gestation) among neonatal consultants in the West ...

Intolerance to volume expansion: a theorized mechanism for the development of preeclampsia
Obstetrics & Gynecology, 1998We present a theorized mechanism for the development of preeclampsia, suggesting that one important underlying pathophysiologic mechanism is intolerance to volume expansion. The stage is set for this intolerance by chronic volume constriction, which leads to a requirement for increased basal peripheral vasoconstrictor tone to maintain blood pressure ...

Role of Volume Expansion in Severe Preeclampsia
Survey of Anesthesiology, 1989Fifteen primigravid patients with severe pregnancy-induced hypertension were studied by catheterization of the right side of the heart. A hemodynamic protocol was implemented that required maintaining colloid osmotic pressure above 17 millimeters of mercury, pulmonary capillary wedge pressure below 15 millimeters of mercury and the mean arterial ...

On the role of the interstitial volume in the response of the rat to blood volume expansion
Pfl�gers Archiv European Journal of Physiology, 1975Patterns of body fluid distribution and selected cardiovascular and renal responses were studied following vascular expansion in normal rats and in rats with altered interstitial fluid volume produced by dehydration, prehydration or hyperoncotic albumin infusion.

Sodium Retention and Volume Expansion as Mechanisms
American Journal of Hypertension, 1991After nephrectomy, the level of arterial pressure is determined by the permitted degree of fluid volume expansion. With kidneys present, the fundamental requirement for fluid volume homeostasis is met by maintaining the balance between sodium and water intake and output.

Anionic polymerization with expansion in volume
Journal of Polymer Science Part A: Polymer Chemistry, 1987AbstractNew bicyclic and tricyclic compounds have been synthesized by the Lewis acid‐catalyzed condensation of epoxides with cyclic acid anhydrides or cyclic bislactones. These materials take part in the anionic addition polymerization of amine‐functional polyamides with diepoxides, and modify the shrinkage that is characteristic of the reaction. It is
