RV Pelagia
RV ''Pelagia'' is a research vessel in the service of the Royal Netherlands Institute of Sea Research (NIOZ), a research institute of the Dutch Research Council (NWO). It was built in 1991 by Verolme Shipyard in Heusden, The Netherlands, and has been in NIOZ-service since. The RV ''Pelagia'' is due to be replaced but on 14 April 2022 a Dutch court ruled that the original contract must be amended, resulting in a delay of the final tender for the replacement that will bear the name RV ''Anna Weber-van Bosse'', after the Netherlands' first female marine biologist to conduct research at sea.

Texel
Texel (; Texels dialect: ) is a municipality and an island with a population of 13,643 in North Holland, Netherlands. It is the largest and most populated island of the West Frisian Islands in the Wadden Sea. The island is situated north of Den Helder, northeast of Noorderhaaks, and southwest of Vlieland. Name The name ''Texel'' is Frisian, but because of historical sound-changes in Dutch, where all -x- sounds have been replaced with -s- sounds (compare for instance English ''fox'', Frisian ''fokse'', German ''Fuchs'' with Dutch ''vos''), the name is typically pronounced ''Tessel'' in Dutch. History The All Saints' Flood (1170) created the islands of Texel and Wieringen from North Holland. In the 13th century Ada, Countess of Holland was held prisoner on Texel by her uncle, William I, Count of Holland. Texel received city rights in 1415. The first Dutch expedition to the Northwest Passage departed from the island on the 5th of June, 1594. Texel was involved in the Battl ...

Diesel–electric Transmission
A diesel–electric transmission, or diesel–electric powertrain is a transmission system for vehicles powered by diesel engines in road, rail, and marine transport. Diesel–electric transmission is based on petrol–electric transmission, a very similar transmission system used for petrol engines. Diesel–electric transmission is used on railways by diesel–electric locomotives and diesel–electric multiple units, as electric motors are able to supply full torque at 0 RPM. Diesel–electric systems are also used in marine transport, including submarines, and on some land vehicles. Description The defining characteristic of diesel–electric transmission is that it avoids the need for a gearbox, by converting the mechanical force of the diesel engine into electrical energy (through a dynamo), and using the electrical energy to drive traction motors, which propel the vehicle mechanically. The traction motors may be powered directly or via rechargeable batteries, makin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dutch Research Council
The Dutch Research Council (NWO, Dutch: Nederlandse Organisatie voor Wetenschappelijk Onderzoek) is the national research council of the Netherlands. NWO funds thousands of top researchers at universities and institutes and steers the course of Dutch science by means of subsidies and research programmes. NWO promotes quality and innovation in science. NWO is an independent administrative body under the auspices of the Dutch Ministry of Education, Culture and Science. NWO directs its approximate budget of 1 billion euros towards Dutch universities and institutes, often on a project basis. Also, NWO has its own research institutes and facilitates international cooperation. Current president of NWO since April 1st, 2021 is Marcel Levi. Former NWO presidents include Stan Gielen, Peter Nijkamp and Jos Engelen. NWO is also known for the annual Spinoza and Stevin Prizes.

Heusden
Heusden () is a municipality and a town in the South of the Netherlands. It is located between the towns of Waalwijk and 's-Hertogenbosch. The municipality of Heusden, including Herpt, Heesbeen, Hedikhuizen, Doeveren, and Oudheusden, merged with Drunen and Vlijmen in 1997, giving the municipality its current form. The middle part of national park the Loonse en Drunense Duinen is located in the municipality of Heusden. Population centres Heusden town Before 1997, Heusden was a municipality in itself, that included the communities of Herpt, Heesbeen, Hedikhuizen, Doeveren, and Oudheusden. Castle The settlement of Heusden on the river Meuse (Maas) started with the construction of Heusden Castle, which replaced an earlier castle destroyed by the Duke of Brabant in 1202. This fortification was quickly expanded with water works and a donjon (castle keep). The city of Heusden received city rights in 1318. Heusden's castle had belonged to successive dukes of Brabant; in 1357 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anna Weber-van Bosse
Anna Antoinette Weber-van Bosse (27 March 1852 – 29 October 1942) was a Dutch phycologist, specializing in marine algae. Life Her interest in botany and zoology started at a young age, inspired by regular trips to the Amsterdam zoo. She attended the University of Amsterdam in 1880, where she was made to do her laboratory work in a room separate from the male students. Some of her greatest work comes from the ''Siboga'' Expedition, considered the most important expedition for marine phycology in the western Pacific for the nineteenth century. She ventured with her husband, Max Weber. These travels brought about numerous discoveries, including entire new genera of algae, such as '' Periphykon'', '' Exophyllum'', and '' Microphyllum''. Much of her discoveries from this trip are documented in her monograph ''Corallinaceae'' (1904), and her four-volume ''Liste des algues du Siboga'' (1913-1928). Some of her discoveries came during earlier expeditions to northern Norway and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remotely Operated Vehicle
A remotely operated underwater vehicle (technically ROUV or just ROV) is a tethered underwater mobile device, commonly called ''underwater robot''. Definition This meaning is different from remote control vehicles operating on land or in the air. ROVs are unoccupied, usually highly maneuverable, and operated by a crew either aboard a vessel/floating platform or on proximate land. They are common in deepwater industries such as offshore hydrocarbon extraction. They are linked to a host ship by a neutrally buoyant tether or, often when working in rough conditions or in deeper water, a load-carrying umbilical cable is used along with a tether management system (TMS). The TMS is either a garage-like device which contains the ROV during lowering through the splash zone or, on larger work-class ROVs, a separate assembly which sits on top of the ROV. The purpose of the TMS is to lengthen and shorten the tether so the effect of cable drag where there are underwater currents is minimize ...

Conductivity, Temperature, Depth
''For information about the CTD-rosette equipment package as a whole, see: Rosette sampler'' A CTD or sonde is an oceanography instrument used to measure the electrical conductivity, temperature, and pressure of seawater (the D stands for "depth," which is closely related to pressure). Conductivity is used to determine salinity. The CTD may be incorporated into an array of Niskin bottles referred to as a carousel or rosette. The sampling bottles close at predefined depths, triggered either manually or by a computer, and the water samples may subsequently be analyzed further for biological and chemical parameters. The CTD may also be used for the calibration of sensors. Measured properties The instrument is a cluster of sensors which measure conductivity, temperature, and pressure. Sensors commonly scan at a rate of 24 Hz. Depth measurements are derived from measurement of hydrostatic pressure, and salinity is measured from electrical conductivity. Sensors are arran ...

Piston Core
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts downwards through the connecting rod and onto the crankshaft. The connecting rod is att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
