Stem flow measurement on a silver birch. There are a variety of ways stemflow volume is measured in the field. The most common direct measurement currently used is the bonding of bisected PVC or other plastic tubing around the circumference of the tree trunk, connected and funneled into a graduated cylinder for manual or a tipping bucket rain gauge for automatic collection.
Plume shapes can be influenced by flow in the ambient fluid (for example, if local wind blowing in the same direction as the plume results in a co-flowing jet). This usually causes a plume which has initially been 'buoyancy-dominated' to become 'momentum-dominated' (this transition is usually predicted by a dimensionless number called the ...
The conversion between heat flow and current flow, and the reverse. thermostat A temperature sensing switch. Thévenin theorem A theorem which states that any network of current sources, voltage sources and resistors can be simplified to an equivalent network with only a voltage source and series impedance; the dual of Norton's Theorem. third rail
Today CD133 is the most commonly used marker for isolation of cancer stem cell (CSC) population from different tumors, mainly from various gliomas and carcinomas. [16] Initial studies that showed ability of CD133-positive population to efficiently propagate tumor when injected into immune-compromised mice firstly were performed on brain tumors.
The only type of Mach reflection possible in steady flow is direct-Mach reflection, in which the Mach stem is convex away from the oncoming flow, and the slip plane slopes towards the reflecting surface. By new results [3] [4] [5] there is a new configuration of shock waves - configuration with a negative angle of reflection in steady flow ...
The airport is full of spending temptations at every corner, and it’s easy to give into those temptations when you have time to kill before your flight. According to a recent survey from ...
