Gentrification is a process that has inherent class connotations and is an extremely visible process that plays a key role in the physical and social form of contemporary cities. Gentrification is intertwined with change; as the community's buildings undergo renovation and beautification, rents increase, resulting in a displacement of longtime (and often lower-income) residents, who are replaced by more affluent ones (see yuppies). Sociologist Ruth Glass coined the term in 1964, which she defined using London districts such as Islingt ...

Once this process of 'gentrification' starts in a district it goes on rapidly until all or most of the original working-class occupiers are displaced and the whole social cha ...

Uhthoff's phenomenon is the worsening of neurologic symptoms in multiple sclerosis after periods of exercise and increased body heat. Uhthoff's phenomenon - History. First described by Wilhelm Uhthoff in 1890 as a temporary worsening of vision with exercise in patients with optic neuritis, later work revealed the link between exercise and increased heat production. The phenomenon can occur with any neurologic deficit caused by demyelination and is possibly due to the effect of increased temperature ...

The Aristarchus crater is located on an elevated rocky plateau, known as the Aristarchus plateau, in the midst of the Oceanus Procellarum lava plain. It is just to ...

A rainbow is an optical and meteorological phenomenon that causes a nearly continuous spectrum of light to appear in the sky when the Sun shines onto falling rain. It is a multicoloured arc with red on the outside and violet on the inside. The full sequence of colours is most commonly cited as red, orange, yellow, green, blue, indigo, and violet, though it is important to note that this is an inconsistent list; all primary and secondary colours are present in some form, but only one tertiary colour. It is commonly thought that indigo ...
