Reykjavík Green Days
The Reykjavík Green Days is an annual event which takes place in Reykjavík, Iceland. This event was founded by a group of students at the University of Iceland The University of Iceland ( is, Háskóli Íslands ) is a public research university in Reykjavík, Iceland and the country's oldest and largest institution of higher education.

"Gaia", as the group is known, aims to raise awareness and stimulate citizens, businesses, non-governmental organizations, local authorities and other urban actors to improve the environment's quality by implementing changes in behavior. It's considered by the Reykjavík town Council an environmental education initiative that encourages all stakeholders to take steps towards becoming more environmentally responsible. The initiave has been organized by the SEED Iceland association in collaboration with other minor local in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reykjavík
Reykjavík ( ; ) is the capital and largest city of Iceland. It is located in southwestern Iceland, on the southern shore of Faxaflói bay. Its latitude is 64°08' N, making it the world's northernmost capital of a sovereign state. With a population of around 131,136 (and 233,034 in the Capital Region), it is the centre of Iceland's cultural, economic, and governmental activity, and is a popular tourist destination. Reykjavík is believed to be the location of the first permanent settlement in Iceland, which, according to Landnámabók, was established by Ingólfr Arnarson in 874 CE. Until the 18th century, there was no urban development in the city location. The city was officially founded in 1786 as a trading town and grew steadily over the following decades, as it transformed into a regional and later national centre of commerce, population, and governmental activities. It is among the cleanest, greenest, and safest cities in the world. History According to lege ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

University Of Iceland
The University of Iceland ( is, Háskóli Íslands ) is a public research university in Reykjavík, Iceland and the country's oldest and largest institution of higher education. Founded in 1911, it has grown steadily from a small civil servants' school to a modern comprehensive university, providing instruction for about 14,000 students in twenty-five faculties. Teaching and research is conducted in social sciences, humanities, law, medicine, natural sciences, engineering and teacher education. It has a campus concentrated around ''Suðurgata'' street in central Reykjavík, with additional facilities located in nearby areas as well as in the countryside. History The University of Iceland was founded by the Alþingi on 17 June 1911, uniting three former post-secondary institutions: ''Prestaskólinn'', ''Læknaskólinn'' and ''Lagaskólinn'', which taught theology, medicine and law, respectively. The university originally had only faculties for these three fields, in addition to a fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critical Mass
In nuclear engineering, a critical mass is the smallest amount of fissile material needed for a sustained nuclear chain reaction. The critical mass of a fissionable material depends upon its nuclear properties (specifically, its nuclear fission cross-section), density, shape, enrichment, purity, temperature, and surroundings. The concept is important in nuclear weapon design. Explanation of criticality When a nuclear chain reaction in a mass of fissile material is self-sustaining, the mass is said to be in a ''critical'' state in which there is no increase or decrease in power, temperature, or neutron population. A numerical measure of a critical mass is dependent on the effective neutron multiplication factor , the average number of neutrons released per fission event that go on to cause another fission event rather than being absorbed or leaving the material. When ''k'' = 1, the mass is critical, and the chain reaction is self-sustaining. A ''subcritical'' mass is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Awareness Days
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term ''environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its conditions. S ...
