Ligand-protein affinities are influenced by non-covalent intermolecular interactions between the two molecules such as hydrogen bonding, electrostatic interactions, hydrophobic and Van der Waals forces.

The Van der Waals equation of state may be written:

With the reduced state variables, i. e. V < sub > r </ sub >= V < sub > m </ sub >/ V < sub > c </ sub >, P < sub > r </ sub >= P / P < sub > c </ sub > and T < sub > r </ sub >= T / T < sub > c </ sub >, the reduced form of the Van der Waals equation can be formulated:

The first stable mathematical model of an electronic oscillator, the Van der Pol oscillator, was derived by Balthasar van der Pol in 1927.

At the start of 1986, Essendon were considered unbackable for three successive flags, but a succession of injuries to key players Paul Van der Haar ( only fifteen games from 1986 to 1988 ), Tim Watson, Darren Williams, Roger Merrett and Simon Madden led the club to win only eight of its last eighteen games in 1986 and only nine games ( plus a draw with Geelong ) in 1987.

Van der Waerden gives both the modern formula and what amounts to the form preferred by Robson.

Van der Berghe states the sense of family attachments among related people as creating durable, intense, emotional, and cooperative attachments, that he claims are utilized within ethnic groups.

Van der Berghe identifies genetic-relatedness as being a basis for the durable attachments of family groups, as genetic ties cannot be removed and they are passed on from generation to generation.

The Flemish Primitives were a group of painters active primarily in the Southern Netherlands in the 15th and early 16th centuries ( for example, Van Eyck and van der Weyden ).

Van der Weyden left no self portraits.

Van der Weyden worked from life models, and his observations were acute, yet he often idealised certain elements of his models ' facial features, and they are typically statuesque, especially in his triptychs.

Nothing seems more natural than the conjunction of his name with that of Memling as the author of an altarpiece, since, though Memling's youth remains obscure, it is clear from the style of his manhood that he was taught in the painting-room of Van der Weyden.

Nor is it beyond the limits of probability that it was Van der Weyden who received commissions at a distance from Brussels, and first took his pupil to Bruges, where he afterwards dwelt.

In this altarpiece, which is a triptych ordered for a patron of the house of Sforza, we find the style of Van der Weyden in the central panel of the Crucifixion, and that of Memling in the episodes on the wings.

Of the same years is the Crucifixion in the Royal Museum of Antwerp: his early works shows a marked Flemish influence, which it is now understood he derived from his master Colantonio and from works by Rogier van der Weyden and Jan van Eyck that belonged to Colantonio's patron, Alfonso V of Aragon ; his biographer Vasari remarked that Antonello saw at Naples an oil painting by Jan Van Eyck ( the " Lomellini Tryptych ") belonging to King Alfonso V of Aragon ; Vasari's further narrative, that being struck by the new method, set out for the Netherlands to acquire a knowledge of the process from Van Eyck's disciples is discredited today.

Some scholars have even attributed the famous Deposition in the Prado ( Madrid ) to Campin rather than Van der Weyden.
