Stellenbosch University
Stellenbosch University ( af, Universiteit Stellenbosch) is a public research university situated in Stellenbosch, a town in the Western Cape province of South Africa. Stellenbosch is the oldest university in South Africa and the oldest extant university in Sub-Saharan Africa, together with the University of Cape Town - which received full university status on the same day in 1918. Stellenbosch University (abbreviated as SU) designed and manufactured Africa's first microsatellite, SUNSAT, launched in 1999. Stellenbosch University was the first African university to sign the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities. The students of Stellenbosch University are nicknamed "Maties". The term probably arises from the Afrikaans word "tamatie" (meaning tomato, and referring to the maroon sports uniforms and blazer colour). An alternative theory is that the term comes from the Afrikaans colloquialism ''maat'' (meaning "buddy" or "mate"), originall ...

Academic Staff Of Stellenbosch University
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

Women Biochemists
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as " women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular th ...

South African Broadcasting Corporation
The South African Broadcasting Corporation (SABC) is the public broadcaster in South Africa, and provides 19 radio stations ( AM/ FM) as well as six television broadcasts to the general public. It is one of the largest of South Africa's state-owned enterprises. Opposition politicians and civil society often criticise the SABC, accusing it of being a mouthpiece for whichever political party is in majority power, thus currently the ruling African National Congress; during the apartheid era it was accused of playing the same role for the National Party government. Company history Early years Radio broadcasting in South Africa began in 1923, under the auspices of South African Railways, before three radio services were licensed: the Association of Scientific and Technical Societies (AS&TS) in Johannesburg, the Cape Peninsular Publicity Association in Cape Town and the Durban Corporation, which began broadcasting in 1924. These merged into the African Broadcasting Company in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cortisol
Cortisol is a steroid hormone, in the glucocorticoid class of hormones. When used as a medication, it is known as hydrocortisone. It is produced in many animals, mainly by the '' zona fasciculata'' of the adrenal cortex in the adrenal gland. It is produced in other tissues in lower quantities. It is released with a diurnal cycle and its release is increased in response to stress and low blood-glucose concentration. It functions to increase blood sugar through gluconeogenesis, to suppress the immune system, and to aid in the metabolism of fat, protein, and carbohydrates. It also decreases bone formation. Many of these functions are carried out by cortisol binding to glucocorticoid or mineralocorticoid receptors inside the cell, which then bind to DNA to impact gene expression. Health effects Metabolic response Metabolism of glucose In general, cortisol stimulates gluconeogenesis (the synthesis of 'new' glucose from non-carbohydrate sources, which occurs mainl ...
