Gunther Eheim
Gundaharius or Gundahar (died 437), better known by his legendary names Gunther ( gmh, Gunther) or Gunnar ( non, Gunnarr), was a historical king of Burgundy in the early 5th century. Gundahar is attested as ruling his people shortly after they crossed the Rhine into Roman Gaul. He was involved in the campaigns of the failed Roman usurper Jovinus before the latter's defeat, after which he was settled on the left bank of the Rhine as a Roman ally. In 436, Gundahar launched an attack from his kingdom on the Roman province of Belgica Prima. He was defeated by the Roman general Flavius Aetius, who destroyed Gundahar's kingdom with the help of Hunnish mercenaries the following year, resulting in Gundahar's death. The historical Gundahar's death became the basis for a tradition in Germanic heroic legend in which the legendary Gunther met his death at the court of Attila the Hun (Etzel/Atli). The character also became attached to other legends: most notably he is associated with Sieg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquarium
An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C. Grier (2008) "Pet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garden Pond
A garden pond is a water feature constructed in a garden or designed landscape, normally for aesthetic purposes, to provide wildlife habitat, or for swimming. Habitat Garden ponds can be excellent wildlife habitats, and can make a contribution to the protection of freshwater wildlife. Invertebrate animals such as dragonflies and water beetles, and amphibians can colonise new ponds quickly. Garden pond owners have the potential to make many original and valuable observations about the ecology of small waterbodies, which garden ponds replicate. Garden ponds also cause problems. In particular, garden ponds can be pathways for the spread of invasive non-native plants. In the UK the non-native species ''Crassula helmsii'' and ''Myriophyllum aquaticum'', which cause considerable practical problems in protecting freshwaters, are both escaped invasive species from garden ponds. Conditions Ponds may be created by natural processes or by people; however, the origin of the hole in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Filter
A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents, for purposes such as: providing agricultural irrigation, accessible drinking water, public and private aquariums, and the safe use of ponds and swimming pools. Methods of filtration Filters use sieve, sieving, adsorption, ion exchanges, biofilms and other processes to remove unwanted substances from water. Unlike a sieve or Screen filter, screen, a filter can potentially remove particles much smaller than the holes through which its water passes, such as Nitrates or germs like ''Cryptosporidium.'' Among the methods of filtration, notable examples are Sedimentation (water treatment), sedimentation, used to separate hard and suspended solids from water and Activated Charcoal, activated charcoal treatment, where the boiled water is poured through a piece of cloth to trap undesired residuals.

Pump
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: ''direct lift'', ''displacement'', and ''gravity'' pumps. Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis. When a casing contains only one revolving impeller, it is called a single-stage pump. Whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquarium Fish Feeder
Aquarium fish feeders are electric or electronic devices that are designed to feed aquarium fish at regular intervals. They are often used to feed fish when the aquarist is on vacation or is too busy to maintain a regular feeding schedule. Design Fish feeders are usually clamped to the wall of the tank just over the water. Most designs consist of a hopper which is loaded with a variety of dry food, a timer which rotates the hopper at regular intervals (dispensing food in the process), and a method of setting the interval between feeding and the amount of food dispensed. Some designs have individual small hoppers. Whilst this limits the absolute number of feeds, it does allow for more accurate dosing, and delivery of mixed, (both flake and pellet), foodstuffs, which are often important for community tanks. Most feeders can dispense flake, pellet, or freeze dried food. Benefits of electronic aquarium feeders The benefits of electronic aquarium feeders are not only that the fish a ...

Water Cooling
Cooling tower and water discharge of a nuclear power plant Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations. Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs. Other uses include the cooling of lubricant oil in pumps; for cooling purposes in heat exchangers; for cooling buildings in HVAC and in chillers. Mechanism Advantages Water is inexpensive, non-toxic, and available over most of the earth's surface. Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing ...

Overclocking
In computing, overclocking is the practice of increasing the clock rate of a computer to exceed that certified by the manufacturer. Commonly, operating voltage is also increased to maintain a component's operational stability at accelerated speeds. Semiconductor devices operated at higher frequencies and voltages increase power consumption and heat. An overclocked device may be unreliable or fail completely if the additional heat load is not removed or power delivery components cannot meet increased power demands. Many device warranties state that overclocking or over-specification voids any warranty, however there are an increasing number of manufacturers that will allow overclocking as long as performed (relatively) safely. Overview The purpose of overclocking is to increase the operating speed of a given component. Normally, on modern systems, the target of overclocking is increasing the performance of a major chip or subsystem, such as the main processor or graphics cont ...

Rolf C
Rolf is a male given name and a surname. It originates in the Germanic name ''Hrolf'', itself a contraction of ''Hrodwulf'' ( Rudolf), a conjunction of the stem words ''hrod'' ("renown") + ''wulf'' ("wolf"). The Old Norse cognate is ''Hrólfr''. An alternative but less common variation of ''Rolf'' in Norway is ''Rolv''. The oldest evidence of the use of the name Rolf in Sweden is an inscription from the 11th century on a runestone in Forsheda, Småland. The name also appears twice in the Orkneyinga sagas, where a scion of the jarls of Orkney, Gånge-Rolf, is said to be identical to the Viking Rollo who captured Normandy in 911. This Saga of the Norse begins with the abduction of Gói daughter by a certain Hrolf of Berg, (the Mountain). She is the daughter of Thorri, a Jotun of Gandvik, and sister of Gór and Nór. The latter is regarded as a first king and eponymous anchestor of Nórway. After a fierce duell (Holmgang) where none is able to overcome the other, Hrolf and Nór becom ...
