The chromatography was done at 6-degrees-C using gradient elution, essentially according to Sober and Peterson.

The deep concave gradient employed ( fig. 2 ) was obtained with a nine-chambered gradient elution device ( `` Varigrad '', reference ( 8 ) ) and has been described elsewhere.

The other, a shallow concave gradient ( Fig. 1 ), was produced with a so-called `` cone-sphere '' apparatus, the `` cone '' being a 2-liter Erlenmeyer flask and the `` sphere, '' a 2-liter round-bottom flask.

When the early part of the gradient was flattened, either by using the gradient shown in Fig. 2 or by allowing the `` cone-sphere '' gradient to become established more slowly, Region 2 activity could sometimes be separated into two areas ( donors P. J. and R. S., Fig. 1 and E. M., Fig. 2 ).

For example, if a concentration gradient was established by dissolving KCl in half of a divided vessel that was originally full of H < sub > 2 </ sub > O, and then a membrane permeable to K < sup >+</ sup > ions was introduced between the two halves — empirically, an equilibrium situation would arise where the chemical concentration gradient ( that would normally cause ions to move from the region of high concentration to the region of low concentration ) could be balanced by an electrical gradient that opposes the movement of charge.

Higher levels of carbon dioxide in the atmosphere are thought to have caused the world temperature gradient from north to south to become almost flat: temperatures were about the same across the planet.

A vector field that has circulation about a point cannot be written as the gradient of a function.

Movement is due to the pressure gradient force ( horizontal differences in atmospheric pressure ) and the Coriolis effect, caused by the earth spinning about its axis.

The temperature increases by as much as 30 ° C ( about 50 ° F ) for every kilometer locally in the upper part of the crust, but the geothermal gradient is smaller in deeper crust.

It is remarkably flat ; from its origin near Breckenridge, Minnesota to the international border near Emerson, Manitoba, its gradient is only about 1: 5000 ( 1 metre per 5 kilometres ), or approximately 1 foot per mile.

The steepness gradient of most guyots is about 20 degrees.

The races traverses, and finishes, at the summit of the Mur de Huy ( English: Wall of Huy ), a climb of about 1 kilometer with an average gradient of 10 %, with sections of 20 %.

The most effective distance between electrodes occurs at an electric potential gradient of about 10 kV / cm, which is just below the nominal breakdown voltage of air between two sharp points, at a current density level usually referred to as the saturated corona current condition.

The 200m deep gorge was formed about a million years ago when movements along a fault in the Earth's crust steepened the river's gradient.

Initially, the train made progress up the steep gradient at about 10 mph but stalled about 200 yards before the top of the gradient.

With an engine of similar performance but a much lighter train ( six vehicles ) it was managing about 25 mph up the gradient when at a distance of about 500 yards the driver of the ordinary train saw the approaching runaway vehicles: he braked his train, and had reduced speed to 5 mph at the moment of collision.

This resulted in the road being rerouted through pasture to the east of the original road, taking a right hand bend about south of The Old Mill, taking a 5. 5 % gradient, and rejoining the original road north of The Kell.

Its highest point ( near Fujimi Station ) is about 900 meters above sea level and much of the line has a gradient of 25 per mil.

This verse is shown on blue / white vertical gradient when about: mozilla is entered into the location bar.

This alteration is evident today where the road surface near the summit ( opposite Craigholm ) runs through a cutting and where the pavement ( following the original gradient of the hill ) can be seen to rise about 1-2 metres above the present-day road surface.

Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration, but it is important to note that diffusion also occurs when there is no concentration gradient.

Based on Kinsey's scale where 0 represents a person with an exclusively heterosexual response and 6 represents a person with an exclusively homosexual one, and numbers in between represent a gradient of responses with both sexes, 6 % of those interviewed ranked as a 6: exclusively homosexual.

When one tries to minimize this cost using gradient descent for the class of neural networks called multilayer perceptrons, one obtains the common and well-known backpropagation algorithm for training neural networks.

In underwater acoustics, refraction is the bending or curving of a sound ray that results when the ray passes through a sound speed gradient from a region of one sound speed to a region of a different speed.

* Permeability is the rate in which water flows, and this is measured in gallons per day through a one square foot cross section under a unit hydraulic gradient.

* The gradient is a generalization of the concept of slope for functions of more than one variable.

As such, the temperatures can vary as much as 18 ° F ( 10 ° C ) between inland areas and the coast, with a temperature gradient of over one degree per mile ( 1. 6 km ) from the coast inland.

If the vertical temperature gradient is + 12. 9 ° C per 100 meters ( where the positive sign means temperature gets hotter as one goes higher ), then horizontal light rays will just follow the curvature of the Earth, and the horizon will appear flat.

Drainage throughout most of Guyana is poor and river flow sluggish because the average gradient of the main rivers is only one meter every five kilometers.

Tidal locking ( or captured rotation ) occurs when the gravitational gradient makes one side of an astronomical body always face another, an effect known as synchronous rotation.

For example, a bar may be cold at one end and hot at the other, but after a state of steady state conduction is reached, the spatial gradient of temperatures along the bar does not change any further, as time proceeds.

The high curvature produces a high potential gradient around one electrode.

Heat emitters are usually placed at one end of the enclosure to allow for a temperature gradient, so a reptile may move to the other end of the enclosure if it needs to cool itself.

Two tracks are marked, a steep one up the exposed face, or an easier gradient through bushland around the back.

Specialized trans-membrane proteins recognize the substance and allows it access ( or, in the case of secondary transport, expend energy on forcing it ) to cross the membrane when it otherwise would not, either because it is one to which the phospholipid bilayer of the membrane is impermeable or because it is moved in the direction of the concentration gradient.

Antiport and symport are associated with secondary active transport, meaning that one of the two substances are transported in the direction of their concentration gradient utilizing the energy derived from the transport of second substance ( mostly Na +, K + or H +) down its concentration gradient.

Symport uses the downhill movement of one solute species from high to low concentration to move another molecule uphill from low concentration to high concentration ( against its electrochemical gradient ).

Because of the diversity of vector products ( scalar, dot, cross ) one application of del already gives rise to three major derivatives: the gradient ( scalar product ), divergence ( dot product ), and curl ( cross product ).

For this reason, one must either modify the formulation to ensure that it's a minimization problem ( for example, by extremizing the square of the gradient of the Lagrangian as below ), or else use an optimization technique that finds stationary points ( such as Newton's method without an extremum seeking line search ) and not necessarily extrema.

By adjusting the tilt, which adds a controlled phase gradient to the fringe pattern, one can control the spacing and direction of the fringes, so that one may obtain an easily interpreted series of nearly parallel fringes rather than a complex swirl of contour lines.

The first one is obtaining its implicit form, from which the normal follows readily as the gradient
