The mosaic crystal model goes back to a theoretical analysis of X-ray diffraction by C. G. Darwin (1922). Currently, most studies follow Darwin in assuming a Gaussian distribution of crystallite orientations centered on some reference orientation. The mosaicity is commonly equated with the standard deviation of this distribution.
Building on the fluid mosaic model, a framework called the proteolipid code was proposed in order to explain membrane organization. [8] The proteolipid code relies on the concept of a zone, which is a functional region of membrane that is assembled and stabilized with both protein and lipid dependency.
Fluid mosaic model of a cell membrane. The fluid mosaic model explains various characteristics regarding the structure of functional cell membranes.According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded.
The mosaics form a part of a larger commission by the Belgian financier Adolphe Stoclet and his wife Suzanne. The Stoclets hired the architect Josef Hoffmann and the Wiener Werkstätte artistic collective (‘Viennese Workshop’) to design, decorate and furnish a spacious mansion with formal gardens.
Basilica of San Vitale, Ravenna, 548. Italy has the richest concentration of Late Antique and medieval mosaics in the world. Although the art style is especially associated with Byzantine art and many Italian mosaics were probably made by imported Greek-speaking artists and craftsmen, there are surprisingly few significant mosaics remaining in the core Byzantine territories.
This model differs from older cell membrane structure concepts such as the Singer-Nicolson fluid mosaic model and the Saffman-Delbrück two-dimensional continuum fluid model that view the membrane as more or less homogeneous. The fences and pickets model was proposed to explain observations of molecular traffic made due to recent advances in ...
An architectural model is a type of scale model made to study aspects of an architectural design or to communicate design intent. They are made using a variety of materials including paper, plaster , plastic , resin , wood, glass, and metal .
The Fordington mosaic was discovered in 1903 on the site of Lott & Walne's Fordington foundry, and it was excavated in October 1927 with the help of poet Thomas Hardy, [7] who as a result of excavating the mosaic became ill and died shortly after. The mosaic was lifted from a pit which reached around 2 metres (6.6 ft) in depth. [8]
