Animal cell hydraulics.
Water is the dominant ingredient of cells and its dynamics are crucial to life. We and others have suggested a physical picture of the cell as a soft, fluid-infiltrated sponge, surrounded by a water-permeable barrier. To understand water movements in an animal cell, we imposed an external, inhomogeneous osmotic stress on cultured cancer cells. This forced water through the membrane on one side,...
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 کاملThermal Hydraulics Design Limits
The following discussion of PWR steady state and transient design limits is extracted from the theses of Carter Shuffler and Jarrod Trant while the BWR discussion is extracted from Paolo Ferroni's thesis (covers steady state only). These limits are a simplified and narrower discussion than the relevant NRC standard review plan you will also be referred to. All materials are directly extracted f...
متن کاملFoundations of animal hydraulics: geodesic fibres control the shape of soft bodied animals.
In 1958 R. B. Clark and J. B. Cowey published a paper in which they presented a simple geometric model, based on the idea of a fibre-reinforced cylinder, to explain the mechanism underlying shape changes in ribbon worms and flatworms (Clark and Cowey, 1958). While their results may have been of interest to only a few biologists at that time, the essential idea of this paper, that a structure co...
