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 List of life sciences, areas of the life sciences are being uncovered and developed through biochemical methodology and research.#Voet, Voet (2005), p. 3. Biochemistry focuses on understanding the chemical basis that allows biomolecule, biological molecules to give rise to the processes that occur within living Cell (biology), cells and between cells,#Karp, Karp (2009), p. 2. in turn relating greatly to the understanding of tissue (biology), tissues and organ (anatomy), organs as well as organism structure and function.#Miller, Miller (2012). p. 62.

John Sibthorp
John Sibthorp (28 October 1758 – 8 February 1796) was an English botanist. Education Sibthorp graduated from the University of Oxford in 1777 where he was an undergraduate student at Lincoln College, Oxford. He subsequently studied medicine at the University of Edinburgh and University of Montpellier. Career and research In 1784, he succeeded his father to the Sherardian chair. Leaving his professional duties to a deputy, he left England for Göttingen and Vienna, in preparation for a botanical tour of Greece (1786) and Cyprus (1787). Returning to England at the end of the following year, he took part in the foundation of the Linnean Society of London in 1788, and set to work on a Flora of Oxfordshire, which was published in 1794 as ''Flora Oxoniensis''. He was elected as a Fellow of the Royal Society in Mar 1788. He made a second journey to Greece, but developed consumption on the way home and died in Bath on 8 February 1796. He was buried at Bath Abbey, with a mon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lecturer
Lecturer is an academic rank within many universities, though the meaning of the term varies somewhat from country to country. It generally denotes an academic expert who is hired to teach on a full- or part-time basis. They may also conduct research. Comparison The table presents a broad overview of the traditional main systems, but there are universities which use a combination of those systems or other titles. Note that some universities in Commonwealth countries have adopted the American system in place of the Commonwealth system. Uses around the world Australia In Australia, the term lecturer may be used informally to refer to anyone who conducts lectures at a university or elsewhere, but formally refers to a specific academic rank. The academic ranks in Australia are similar to those in the UK, with the rank of associate professor roughly equivalent to reader in UK universities. The academic levels in Australia are (in ascending academic level): (A) associate lecture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

West Lafayette, Indiana
West Lafayette ( ) is a city in Wabash and Tippecanoe Townships, Tippecanoe County, Indiana, United States, approximately 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 home to Purdue University and is a college town and the most densely populated city in Indiana. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jan Mayen
Jan Mayen () is a Norway, 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 [305 mi] NE of Kolbeinsey), east of central Greenland, and northwest of Vesterålen, 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 Continental fragment, microcontinent. Although administered separately, in the ISO 3166-1 standard, Jan Mayen and Svalbard are collectively designated as ''Svalbard and Jan Mayen'' ...

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 active 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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spitzbergen
Svalbard ( , ), previously known as Spitsbergen or Spitzbergen, is a Norwegian archipelago that lies at the convergence of the Arctic Ocean with the Atlantic Ocean. North of mainland Europe, it lies 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 (37,673 km2), followed in size by Nordaustlandet (14,443 km2), (5,073 km2), and Barentsøya (1,288 km2). Bjørnøya or Bear Island (178 km2) is the most southerly island in the territory, situated some 147 km south of Spitsbergen. Other small islands in the group include Hopen to the southeast of Edgeøya, Kongsøya and Svenskøya in the east, and Kvitøya to the northeast. The largest settlement is Longyearbyen, situated in Isfjorden on the west coast of Spitsbergen. Whalers who sailed far north in the 17th and 18th centuries used the islands as a base; subsequ ...

Hornsund
Hornsund is a fjord on the western side of the southernmost tip of northern Norway's 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, b ...

Plant Biochemistry
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Plant physiologists study fundamental processes of plants, 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. Plant physiology interacts with the fields of plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry (biochemistry of plants), cell biology, genetics, biophysics and molecular biology. 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 and internal diffu ...

British Undergraduate Degree Classification
The British undergraduate degree classification system is a Grading in education, grading structure used for undergraduate degrees or bachelor's degrees and Master's degree#Integrated Masters Degree, integrated master's degrees in the United Kingdom. The system has been applied, sometimes with significant variation, in other countries and regions. The UK's university degree classification system, established in 1918, serves to recognize academic achievement beyond examination performance. Bachelor's degrees in the UK can either be honours or ordinary degrees, with honours degrees classified into First Class, Upper Second Class (2:1), Lower Second Class (2:2), and Third Class based on weighted averages of marks. The specific thresholds for these classifications can vary by institution. Integrated master's degrees follow a similar classification, and there is some room for discretion in awarding final classifications based on a student's overall performance and work quality.
