Research
Research is "creativity, creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, Discovery (observation), discovery, interpretation (philosophy), interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemology, epistemologies, which vary considerably both within and between humanities and sciences. ...

Oskarshamn
Oskarshamn is a coastal city and the seat of Oskarshamn Municipality, Kalmar County, Sweden with 17,258 inhabitants in 2010. History Etymology Döderhultsvik was the original name before a town charter was granted in 1856. The name was then changed to Oscarshamn (meaning: Oscar's port) after the king Oscar I of Sweden. The spelling has later changed to Oskarshamn. Struggle for town charter The location of Oskarshamn was known as Döderhultsvik since the Medieval age. In 1645, the city of Kalmar, to the south, made a request to the Royal Government on holding commerce in the bay there, which was granted, giving it merchancy rights as a ''köping''. There followed 200 years of merchancies in the town, during which it was governed and dependent on Kalmar; while the surrounding towns and municipalities made frequent requests to grant it a charter, consequently turned down each of the attempts made in the years: 1786, 1798, 1800, 1815, 1818, 1823, 1825, 1830 and 1838. In 1843 it got so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalmar County
Kalmar County () is a county or '' län'' in southern Sweden. It borders the counties of Kronoberg, Jönköping, Blekinge and Östergötland. To the east in the Baltic Sea is the island Gotland. The counties are mainly administrative units. Geographically Kalmar County covers the eastern part in the Småland province, and the entire island of Öland. Culture Much of Öland's present day landscape known as the Stora Alvaret has been designated as a World Heritage Site by UNESCO. This southern part of Öland is known for a large number of rare species; early paleolithic settlement at Alby; other prehistoric remains such as the Gettlinge Gravefield and Eketorp Fortress; and the Ottenby Nature Preserve. Administration Kalmar County was integrated with Kronoberg County until 1672. Blekinge was a part of Kalmar County between 1680 and 1683, due to the foundation of the naval base at Karlskrona. The seat of residence for the Governor or ''Landshövding'' is Kalmar. The Govern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oskarshamn Nuclear Power Plant
The Nuclear power station Oskarshamn is one of three active nuclear power stations in Sweden. The plant is about north of Oskarshamn, directly at the Kalmarsund at the Baltic Sea coast and with one active reactor, producing about 10% of the electricity needs of Sweden. All reactors were built using BWR technology. Unit 1 had an installed output of 494 MW and Unit 2 664 MW; these are now decommissioned. Unit 3, the newest reactor block at the facility, has an installed output of 1,450 MW. Clab, the temporary storage facility for spent nuclear fuel from all Swedish reactors, is also located at the site. Operator The responsible utility is OKG, short for the ''Oskarshamnsverkets Kraftgrupp OKG'', which was acquired by Sydkraft in 1993, (later: '' E.ON Sverige''). Uniper owns 54.5% and the other partner Fortum 45.5% of OKG. History On July 25, 2006, Units 1 and 2 were shut down as a precaution after a safety-related incident at an identical reactor at the Fo ...

Geological
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Ear ...

Bedrock
In geology, bedrock is solid Rock (geology), rock that lies under loose material (regolith) within the crust (geology), crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysics, geophysical methods is an important task in most civil engineering projects. Superficial deposition (geology), deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave ...

Nuclear Power In Sweden
The electricity sector in Sweden has three operational nuclear power plants with 6 operational nuclear reactors, which produce about 29.8% of the country's electricity. The nation's largest power station, Forsmark Nuclear Power Plant, has three reactors producing 3.3 GW and 14% of Sweden's electricity. Sweden formerly had a nuclear phase-out policy, aiming to end nuclear power generation in Sweden by 2010. On 5 February 2009, the Government of Sweden announced an agreement allowing for the replacement of existing reactors, effectively ending the phase-out policy. History Early history Sweden began research into nuclear energy in 1947 with the establishment of the Atomic Energy Company, AB Atomenergi, which originated in the ongoing military research and development at the Defence Institute FOA. In 1954, the country built its first small research heavy water reactor, the R1 nuclear reactor. The R1 was dismantled in 1970. It was followed by two heavy water reactors: Ã…gesta or ...

Radioactive Waste Repositories
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay ( ), beta decay ( ), and gamma decay ( ), all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetism and nuclear force. A fourth type of common decay is electron capture, in which an unstable nucleus captures an inner electron from one of the electron shells. The loss of that electron from the shell results in a cascade of electrons dropping down to that lower shell resulting in emission of discrete X-rays from the transitions. A common example is iodine-125 commonly used in medical settings. Radioactive decay is a stochastic (i.e. random) process ...
