Coastal Defense Ship
Coastal defence ships (sometimes called coastal battleships or coast defence ships) were warships built for the purpose of Littoral (military), coastal defence, mostly during the period from 1860 to 1920. They were small, often cruiser-sized warships that sacrificed speed and range for armour and armament. They were usually attractive to nations that either could not afford full-sized battleships or could be satisfied by specially designed shallow-draft vessels capable of littoral operations close to their own shores. The Nordic countries and Thailand found them particularly appropriate for their island-dotted coastal waters. Some vessels had limited Blue-water navy, blue-water capabilities; others operated in Maritime geography#Riverine, rivers. The coastal defence ships differed from earlier Monitor (warship), monitors by having a higher Freeboard (nautical), freeboard and usually possessing both higher speed and a secondary armament; some examples also mounted casemated gun ...

Swedish Navy
The Swedish Navy ( sv, Svenska marinen) is the naval branch of the Swedish Armed Forces. It is composed of surface and submarine naval units – the Fleet () – as well as marine units, the Amphibious Corps (). In Swedish, vessels of the Swedish Navy are given the prefix "HMS", short for (His/Her Majesty's Ship). In English, this is sometimes changed to "HSwMS" ("His Swedish Majesty's Ship") to differentiate Swedish vessels from those of the British Royal Navy. Founded under King Gustav I in 1522, the Swedish navy is one of the oldest continuously serving navies in the world, celebrating its 500th anniversary in 2022. History Early Swedish kings ( 9th–14th centuries) organised a Swedish Navy along the coastline through . This involved combined rowing and sailing ships (without artillery). This system became obsolete with the development of society and changes in military technology. No later than in the 14th century, the duty to serve in was replaced by a tax ...

Reciprocating Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intr ...

Gothenburg
Gothenburg (; abbreviated Gbg; sv, Göteborg ) is the second-largest city in Sweden, fifth-largest in the Nordic countries, and capital of the Västra Götaland County. It is situated by the Kattegat, on the west coast of Sweden, and has a population of approximately 590,000 in the city proper and about 1.1 million inhabitants in the metropolitan area. Gothenburg was founded as a heavily fortified, primarily Dutch, trading colony, by royal charter in 1621 by King Gustavus Adolphus. In addition to the generous privileges (e.g. tax relaxation) given to his Dutch allies from the ongoing Thirty Years' War, the king also attracted significant numbers of his German and Scottish allies to populate his only town on the western coast. At a key strategic location at the mouth of the Göta älv, where Scandinavia's largest drainage basin enters the sea, the Port of Gothenburg is now the largest port in the Nordic countries. Gothenburg is home to many students, as the city includes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nacka
Nacka () is the municipal seat of Nacka Municipality and part of Stockholm urban area in Sweden. The municipality's name harks back to a 16th-century industrial operation established by the Crown at Nacka farmstead where conditions for water mills are good. However, and somewhat confusingly, that spot is not densely populated today and the municipal seat is on land that once belonged to Järla farmstead on the other side of Lake Järla. Events On 9 December 2014, Stockholm police raided a data center in a former bomb shelter under a hill in Nacka municipality. Although it was rumored the raid targeted popular torrent site The Pirate Bay, officials from The Pirate Bay have revealed that this is false.

Aspö
Aspö is a small village on the Aspö Island in Väståboland, Finland. Until 2009 it belonged to the municipality of Korpo. Its Finnish-language name is Haapasaari, although this name is seldom used. The village is known for its white limestone church that has a red brick roof. The current church was built in 1955–1956; however, a church has existed in the place since the Middle Ages. The old church was destroyed in a storm in 1949. History The commercially seafaring Vikings landed on Aspö during the Viking period, 800 - 1050 AD. In the 13th century it also served as a harbour for traders. The trade route was laid between Tallinn, Estonia and Denmark. In the beginning of the 20th century only about 30 people lived on Aspö. Now there are only about 10 people. During World War I until 1917, Aspö served as Russian naval military watchpost. In 1944 it served as the German navy base as the Germans were not allowed to anchor on Åland proper. In the 1910s the Russians had a patr ...
