Gradient

There appear to be mechanisms by which an external chemotactic gradient is sensed and turned into an intracellular PIP3 gradient, which results in a gradient and the activation of a signaling pathway, culminating in the polymerisation of actin filaments.

Whittaker summed the effects of gradients (3) and (4) to get an overall temperature gradient, and combined this with gradient (2), the moisture gradient, to express the above conclusions in what is known as the Whittaker classification scheme.

At the main gallery hall, the alphabet of Kelly’s name unfolded above the over 20 print pieces, and various colours fell in my view: a series of aquatic-themed gradient prints like “” stood out for their gradient backgrounds.

From Paul Klee’s notes, I learned about the natural gradient in contrast to the artificial or step gradient.

At the point a, these partial derivatives define the vector : This vector is called the gradient of f at a. If f is differentiable at every point in some domain, then the gradient is a vector-valued function ∇f that takes the point a to the vector ∇f(a).

For example, the gradient of the function : is: : In some applications it is customary to represent the gradient as a row vector or column vector of its components in a rectangular coordinate system.

If, on a resource gradient, a large number of separate species evolve, each exquisitely adapted to a very narrow band on that gradient, each species will, of necessity, consist of very few members.

Instead of flowing down the gradient, large scale motions in the atmosphere and ocean tend to occur perpendicular to the pressure gradient.

In the presence of a chemical gradient bacteria will chemotax, or direct their overall motion based on the gradient.

It works against the iodide concentration gradient and uses energy of sodium gradient (maintained by the sodium-potassium pump ) and therefore acts by secondary active transport.

One can see the shape from the constant increase of the gradient of the cable with linear (deck) distance, this increase in gradient at each connection with the deck providing a net upward support force.

The pressure gradient is established by the temperature gradient of the plasma; the outer part of the star is cooler than the core.

The salinity gradient is paralleled by a temperature gradient.

The standing gradient osmosis is the reabsorption of water against the osmotic gradient in the intestines.

This creates a proton motive force that is the net effect of a pH gradient and an electric potential gradient across the inner mitochondrial membrane.

This was over four times the maximum gradient recommended for railways of this era, and even modern railways rarely exceed a two-percent gradient.

White (2008). p 63, 66. For instance, the pressure-gradient force prevents gravity from collapsing Earth's atmosphere into a thin, dense shell, whereas gravity prevents the pressure gradient force from diffusing the atmosphere into space.

Although the central pressure of the high will be easing into the upper 1030's by Tuesday, the associated pressure gradient over the islands will tighten.

But we've historically always had a limited range of gradient possibilities with our own mouths, based on diet, genetics and other unique factors.

Due to low business and consumer confidence, the steep gradient of interest rate hikes, and stagnant salaries, rental demand is set to grow in South Africa, said TPN.
