The Queen's College, Oxford
The Queen's College is a Colleges of the University of Oxford, constituent college of the University of Oxford, England. The college was founded in 1341 by Robert de Eglesfield in honour of Philippa of Hainault. It is distinguished by its predominantly neoclassical architecture, which includes buildings designed by Sir Christopher Wren and Nicholas Hawksmoor. In 2018, the college had an endowment of £291 million, making it the fourth-wealthiest college (after Christ Church, Oxford, Christ Church, St. John's College, Oxford, St. John's, and All Souls College, Oxford, All Souls). History The college was founded in 1341 as "Hall of the Queen's scholars of Oxford" by Robert de Eglesfield (d'Eglesfield), chaplain to the Queen, Philippa of Hainault, after whom the hall was named. Robert's aim was to provide clergymen for his native Cumberland and where he lived in Westmorland (both part of modern Cumbria). In addition, the college was to provide charity for the poor.

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycopodiophyta
The lycophytes, when broadly circumscribed, are a vascular plant (tracheophyte) subgroup of the kingdom Plantae. They are sometimes placed in a division Lycopodiophyta or Lycophyta or in a subdivision Lycopodiophytina. They are one of the oldest lineages of extant (living) vascular plants; the group contains extinct plants that have been dated from the Silurian (ca. 425 million years ago). Lycophytes were some of the dominating plant species of the Carboniferous period, and included tree-like species, although extant lycophytes are relatively small plants. The scientific names and the informal English names used for this group of plants are ambiguous. For example, "Lycopodiophyta" and the shorter "Lycophyta" as well as the informal "lycophyte" may be used to include the extinct zosterophylls or to exclude them. Description Lycophytes reproduce by spores and have alternation of generations in which (like other vascular plants) the sporophyte generation is dominant. Some lycophyte ...

Bryophyte
The Bryophyta s.l. are a proposed taxonomic division containing three groups of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses. Bryophyta s.s. consists of the mosses only. They are characteristically limited in size and prefer moist habitats although they can survive in drier environments. The bryophytes consist of about 20,000 plant species. Bryophytes produce enclosed reproductive structures (gametangia and sporangia), but they do not produce flowers or seeds. They reproduce sexually by spores and asexually by fragmentation or the production of gemmae. Though bryophytes were considered a paraphyletic group in recent years, almost all of the most recent phylogenetic evidence supports the monophyly of this group, as originally classified by Wilhelm Schimper in 1879. The term ''bryophyte'' comes . Terminology The term "Bryophyta" was first suggested by Braun in 1864. G.M. Smith placed this group between Algae and Pteridophyta. Features The d ...

Meristem
The meristem is a type of tissue found in plants. It consists of undifferentiated cells (meristematic cells) capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants. These cells continue to divide until a time when they get differentiated and then lose the ability to divide. Differentiated plant cells generally cannot divide or produce cells of a different type. Meristematic cells are undifferentiated or incompletely differentiated. They are totipotent and capable of continued cell division. Division of meristematic cells provides new cells for expansion and differentiation of tissues and the initiation of new organs, providing the basic structure of the plant body. The cells are small, with no or small vacuoles and protoplasm fills the cell completely. The plastids (chloroplasts or chromoplasts), are undifferentiated, but are present in rudimentary form (proplastids). Meristematic cells are packed closely together wi ...

Postdoctoral Researcher
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pursue additional research, training, or teaching in order to have better skills to pursue a career in academia, research, or any other field. Postdocs often, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charing Cross And Westminster Medical School
Charing Cross and Westminster Medical School existed as a legal entity for 13 years, as the midpoint of a series of mergers which strategically consolidated the many small medical schools in west London into one large institution under the aegis of Imperial College London. In 1984, Charing Cross Hospital Medical School and Westminster Hospital Medical School merged to form the Charing Cross and Westminster Medical School. This move was part of a series of mergers in the London medical schools in the early 1980s, which foreshadowed the second, larger round of mergers in the late 1990s. Based at the Charing Cross Hospital site in Hammersmith and Chelsea and Westminster Hospital in Chelsea, the new medical school took the form of its larger precursor ( CXHMS) in using "X" as an abbreviation for "Cross". The medical school also maintained academic units at the university hospitals of Queen Mary's Roehampton, West Middlesex, Ashford and Hillingdon. In 1997, CXWMS merged with Imperia ...

St Mary's Hospital Medical School
St Mary's is the youngest of the constituent schools of Imperial College London, founded in 1854 as part of the new hospital in Paddington. During its existence in the 1980s and 1990s, it was the most popular medical school in the country, with an application to place ratio of 27:1 in 1996. St Mary's continued comparatively unmoved by the other nomadic medical schools in the area, until its merger with Imperial College in 1988, and the foundation of Imperial College School of Medicine in 1997 by the merger with Charing Cross and Westminster Medical School. ''Doctors to Be'' ''Doctors to Be'', a biographical documentary series first broadcast on BBC Two by BBC Television, followed 10 medical students who enrolled at St Mary's Hospital Medical School in the 1985 intake. It started with admission interviews in November 1984, then followed their lives as medical students for five or six years, and ended with their first experiences of working as busy junior hospital doctors in th ...

Human Genetics
Human genetics is the study of inheritance as it occurs in human beings. Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling. Genes are the common factor of the qualities of most human-inherited traits. Study of human genetics can answer questions about human nature, can help understand diseases and the development of effective treatment and help us to understand the genetics of human life. This article describes only basic features of human genetics; for the genetics of disorders please see: medical genetics. Genetic differences and inheritance patterns Inheritance of traits for humans are based upon Gregor Mendel's model of inheritance. Mendel deduced that inheritance depends upon discrete units of inheritance, called factors or genes. Autosomal dominant inheritance Autosomal tr ...
