Biochemistry
Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research. Voet (2005), p. 3. Biochemistry focuses on understanding the chemical basis which allows biological molecules to give rise to the processes that occur within living cells and between cells,Karp (2009), p. 2. in turn relating greatly to the understanding of tissues and organs, as well as organism structure and function.Miller (2012). p. 62. Biochemistry is closely related to molecular biology, which is the study of the molecular mechanisms of biological phenomena.As ...

Fellow
A fellow is a concept whose exact meaning depends on context. In learned or professional societies, it refers to a privileged member who is specially elected in recognition of their work and achievements. Within the context of higher educational institutions, a fellow can be a member of a highly ranked group of teachers at a particular college or university or a member of the governing body in some universities (such as the Fellows of Harvard College); it can also be a specially selected postgraduate student who has been appointed to a post (called a fellowship) granting a stipend, research facilities and other privileges for a fixed period (usually one year or more) in order to undertake some advanced study or research, often in return for teaching services. In the context of research and development-intensive large companies or corporations, the title "fellow" is sometimes given to a small number of senior scientists and engineers. In the context of medical education in No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Lafayette, Indiana
West Lafayette () is a city in Wabash Township, Tippecanoe County, Indiana, United States, about northwest of the state capital of Indianapolis and southeast of Chicago. West Lafayette is directly across the Wabash River from its sister city, Lafayette. As of the 2020 census, its population was 44,595. It is the most densely populated city in Indiana and is home to Purdue University. History Augustus Wylie laid out a town in 1836 in the Wabash River floodplain south of the present Levee. Due to regular flooding of the site, Wylie's town was never built. The present city was formed in 1888 by the merger of the adjacent suburban towns of Chauncey, Oakwood, and Kingston, located on a bluff across the Wabash River from Lafayette, Indiana. The three towns had been small suburban villages which were directly adjacent to one another. Kingston was laid out in 1855 by Jesse B. Lutz. Chauncey was platted in 1860 by the Chauncey family of Philadelphia, wealthy land speculators. Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jan Mayen
Jan Mayen () is a Norwegian volcanic island in the Arctic Ocean with no permanent population. It is long (southwest-northeast) and in area, partly covered by glaciers (an area of around the Beerenberg volcano). It has two parts: larger northeast Nord-Jan and smaller Sør-Jan, linked by a wide isthmus. It lies northeast of Iceland (495 km 05 miNE of Kolbeinsey), east of central Greenland, and west of the North Cape, Norway. The island is mountainous, the highest summit being the Beerenberg volcano in the north. The isthmus is the location of the two largest lakes of the island, Sørlaguna (South Lagoon) and Nordlaguna (North Lagoon). A third lake is called Ullerenglaguna (Ullereng Lagoon). Jan Mayen was formed by the Jan Mayen hotspot and is defined by geologists as a separate continent. Although administered separately, in the ISO 3166-1 standard, Jan Mayen and Svalbard are collectively designated as ''Svalbard and Jan Mayen'', with the two-letter country code "SJ". N ...

Beerenberg
Beerenberg is a stratovolcano dominating the northeastern end of the Norwegian island of Jan Mayen. It is high and is the world's northernmost subaerial active volcano and the List of volcanoes in Norway, only volcano in Norway. The volcano is topped by a mostly ice-filled volcanic crater, crater about wide, with numerous peaks along its rim including the highest summit, Haakon VII Toppen, on its western side. Name Its name is Dutch language, Dutch for "Bear Mountain", and comes from the polar bears seen there by Dutch whalers in the early 17th century. Description The upper slopes of the volcano are largely ice-covered, with several major glaciers including five which reach the sea. The longest of the glaciers is the Weyprecht Glacier, which flows from the summit crater via a breach through the northwestern portion of the crater rim, and extends about down to the sea. Beerenberg is composed primarily of basaltic lava flows with minor amounts of tephra. Numerous cinder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spitzbergen
Svalbard ( , ), also known as Spitsbergen, or Spitzbergen, is a Norwegian archipelago in the Arctic Ocean. North of mainland Europe, it is about midway between the northern coast of Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and . The largest settlement is Longyearbyen. The islands were first used as a base by the whalers who sailed far north in the 17th and 18th centuries, after which they were abandoned. Coal mining started at the beginning of the 20th century, and several permanent communities were established. The Svalbard Treaty of 1920 recognizes Norwegian sovereignty, and the 1925 Svalbard Act made Svalbard a full part of the Kingdom of Norway. They also established Svalbard as a free economic zone and a demilitarized zone. The Norwegian Store Norske and the Russian remain the only mining companies in place. Res ...

Hornsund
Hornsund is a fjord on the western side of the southernmost tip of Spitsbergen island. The fjord's mouth faces west to the Greenland Sea, and is wide. The length is , the mean depth is , and the maximal depth is . Hornsund cuts different geological formations, from the Precambrian to the west to the upper Mesozoic to the east, and it is perpendicular to the main regional fractures of Spitsbergen. The coastline of Hornsund is diversified, with a number of bays at the mouths of mountainous glacial valleys. Some of these bays have appeared as late as the beginning of the last century due to recession of glaciers. A Polish research station has been operating there since 1957. History The English explorer Jonas Poole visited Hornsund in 1610, giving the fjord its name after his men had brought back a reindeer antler. In 1613 the first whaling ships used Hornsund, the majority of which were driven away by the English. In 1614 the fjord was ceded to the Dutch, but only for this ...

Plant Biochemistry
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Closely related fields include plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry (biochemistry of plants), cell biology, genetics, biophysics and molecular biology. Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations, are studied by plant physiologists. Aims The field of plant physiology includes the study of all the internal activities of plants—those chemical and physical processes associated with life as they occur in plants. This includes study at many levels of scale of size and time. At the smallest scale are molecular interactions of photosynthesis ...

British Undergraduate Degree Classification
The British undergraduate degree classification system is a grading structure for undergraduate degrees or bachelor's degrees and integrated master's degrees in the United Kingdom. The system has been applied (sometimes with significant variations) in other countries and regions. History The classification system as currently used in the United Kingdom was developed in 1918. Honours were then a means to recognise individuals who demonstrated depth of knowledge or originality, as opposed to relative achievement in examination conditions. Concern exists about possible grade inflation. It is claimed that academics are under increasing pressure from administrators to award students good marks and grades with little regard for those students' actual abilities, in order to maintain their league table rankings. The percentage of graduates who receive a First (First Class Honours) has grown from 7% in 1997 to 26% in 2017, with the rate of growth sharply accelerating toward the end of ...

Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Southgate Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow the Oxford a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
