Portrait Of Martin William Flack Wellcome L0011820
A portrait is a painting, photograph, sculpture, or other artistic representation of a person, in which the face is always predominant. In arts, a portrait may be represented as half body and even full body. If the subject in full body better represents personality and mood, this type of presentation may be chosen. The intent is to display the likeness, personality, and even the mood of the person. For this reason, in photography a portrait is generally not a snapshot, but a composed image of a person in a still position. A portrait often shows a person looking directly at the painter or photographer, to most successfully engage the subject with the viewer, but portrait may be represented as a profile (from aside) and 3/4. History Prehistorical portraiture Plastered human skulls were reconstructed human skulls that were made in the ancient Levant between 9000 and 6000 BC in the Pre-Pottery Neolithic B period. They represent some of the oldest forms of art in the Middle Eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinoatrial Node
The sinoatrial node (also known as the sinuatrial node, SA node, sinus node or Keith–Flack node) is an ellipse, oval shaped region of special cardiac muscle in the upper back wall of the right atrium made up of Cell (biology), cells known as pacemaker cells. The sinus node is approximately 15 millimetre, mm long, 3 mm wide, and 1 mm thick, located directly below and to the side of the superior vena cava. These cells produce an Action potential, electrical impulse known as a cardiac action potential that travels through the electrical conduction system of the heart, causing it to muscle contraction, contract. In a healthy heart, the SA node continuously produces action potentials, setting the rhythm of the heart (sinus rhythm), and so is known as the heart's cardiac pacemaker, natural pacemaker. The rate of action potentials produced (and therefore the heart rate) is influenced by the nerves that supply it. Structure The sinoatrial node is an Ellipse, oval-shaped structure that ...

Arthur Keith
Sir Arthur Keith FRS FRAI (5 February 1866 – 7 January 1955) was a British anatomist and anthropologist, and a proponent of scientific racism. He was a fellow and later the Hunterian Professor and conservator of the Hunterian Museum of the Royal College of Surgeons of England. He was a strong proponent of the Piltdown Man, but conceded it to be a forgery shortly before his death. Career A leading figure in the study of human fossils, Keith became President of the Royal Anthropological Institute. The latter role stimulated his interest in the subject of human evolution, leading to the publication of his book ''A New Theory of Human Evolution,'' in which he supported the idea of group selection. Where others had postulated that physical separation could provide a barrier to interbreeding, allowing groups to evolve along different lines, Keith introduced the idea of cultural differences as providing a mental barrier, emphasising territorial behaviour, and the concept of the ...

A sister journal, '' Open Heart'', was established in 2010 with the aim of covering cardiovascular research with less emphasis on novelty or priority. History In 2010, ''Heart'' established a sister journal, ''Heart Asia''. It was the official journal of the Asia Pacific Heart Association and aimed to focus on cardiovascular research in the Asia Pacific region. In 2019, the journal ceased publication.

UK Research and Innovation is answerable to, although politically independent from, the Department for Business, Energy and Industrial Strategy. The MRC focuses on high-impact research and has provided the financial support and scientific expertise behind a number of medical breakthroughs, including the development of penicillin and the discovery of the structure of DNA. Research funded by the MRC has produced 32 Nobel Prize winners to date. History The MRC was founded as the Medical Research Committee and Advisory Council in 1913, with its prime role being the distribution of medical research funds under the terms of the National Insurance Act 1911.
