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.
A drawing of a Kaiserpanorama with 25 viewing stations. The Kaiserpanorama (or Kaiser-Panorama) is a form of stereoscopic entertainment medium used chiefly in the 19th and early 20th centuries, and is considered a precursor to film.
The 32-bit/64-bit era is most noted for the rise of fully 3D polygon games. While there were games prior that had used three-dimensional polygon environments, such as Virtua Racing and Virtua Fighter in the arcades and Star Fox on the Super NES, it was in this era that many game designers began to move traditionally 2D and pseudo-3D genres into 3D on video game consoles.
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.
PDF 2.0 defines 256-bit AES encryption as the standard for PDF 2.0 files. The PDF Reference also defines ways that third parties can define their own encryption systems for PDF. PDF files may be digitally signed, to provide secure authentication; complete details on implementing digital signatures in PDF are provided in ISO 32000-2.
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 first version of Sumatra PDF, designated version 0.1, was based on Xpdf 0.2 and was released on 1 June 2006. It switched to Poppler from version 0.2. In version 0.4, it changed to MuPDF for more speed [4] and better support for the Windows platform. Poppler remained as alternative engine for a time, and from version 0.6 to 0.8 it was ...
The Penrose tiling is an example of an aperiodic tiling; every tiling it can produce lacks translational symmetry. An aperiodic tiling using a single shape and its reflection, discovered by David Smith
