With a population of 614,495 inhabitants, it is the largest city (by area and population) of the Ruhr as well as the largest city of Westphalia. It lies on the Emscher and Ruhr rivers (tributaries of the Rhine) in the Rhine-Ruhr Metropolitan Region, the second biggest metropolitan region by GDP in the European Union, and is considered the administrative, commercial, and cultural centre of the eastern Ruhr.

Tributaries
A tributary, or an ''affluent'', is a stream or river that flows into a larger stream ('' main stem'' or ''"parent"''), river, or a lake. A tributary does not flow directly into a sea or ocean. Tributaries, and the main stem river into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean, another river, or into an endorheic basin. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream.

Retail
Retail is the sale of goods and services to consumers, in contrast to wholesaling, which is the sale to business or institutional customers. A retailer purchases goods in large quantities from manufacturers, directly or through a wholesaler, and then sells in smaller quantities to consumers for a profit. Retailers are the final link in the supply chain from producers to consumers. Retail markets and shops have a long history, dating back to antiquity. Some of the earliest retailers were itinerant peddlers. Over the centuries, retail shops were transformed from little more than "rude booths" to the sophisticated shopping malls of the modern era. In the digital age, an increasing number of retailers are seeking to reach broader markets by selling through multiple channels, including both bricks and mortar and online retailing. Digital technologies are also affecting the way that consumers pay for goods and services. Retailing support services may also include the pro ...

Service (economics)
A service is an act or use for which a consumer, company, or government is willing to payment, pay. Examples include work done by barbers, doctors, lawyers, mechanics, banks, insurance companies, and so on. Public services are those that society (nation state, fiscal union or region) as a whole pays for. Using resources, skill, ingenuity, and experience, service providers benefit service consumers. Services may be defined as intangible acts or performances whereby the service provider provides value to the customer. Key characteristics Services have three key characteristics: Intangibility Services are by definition intangible. They are not manufactured, transported or stocked. One cannot store services for future use. They are produced and consumed simultaneously. Perishability Services are perishable in two regards: * Service-relevant resources, processes, and systems are assigned for service delivery during a specific period in time. If the service consumer does not request ...

Micro Systems Technology
MEMS (micro-electromechanical systems) is the technology of microscopic devices incorporating both electronic and moving parts. MEMS are made up of components between 1 and 100 micrometres in size (i.e., 0.001 to 0.1 mm), and MEMS devices generally range in size from 20 micrometres to a millimetre (i.e., 0.02 to 1.0 mm), although components arranged in arrays (e.g., digital micromirror devices) can be more than 1000 mm2. They usually consist of a central unit that processes data (an integrated circuit chip such as microprocessor) and several components that interact with the surroundings (such as microsensors). Because of the large surface area to volume ratio of MEMS, forces produced by ambient electromagnetism (e.g., electrostatic charges and magnetic moments), and fluid dynamics (e.g., surface tension and viscosity) are more important design considerations than with larger scale mechanical devices. MEMS technology is distinguished from molecular nanotechnology ...

Biomedical Technology
Biomedical technology is the application of engineering and technology principles to the domain of living or biological systems, with an emphasis on human health and diseases. Biomedical engineering and Biotechnology alike are often loosely called ''Biomedical Technology'' or Bioengineering. The Biomedical technology field is currently growing at a rapid pace. Biomedical news has often been reported on various platforms, including the MediUnite Journal; and required jobs for the industry expect to grow 23% by 2024, and with the pay averaging over $86,000. Biomedical technology involves: * Biomedical science * Biomedical informatics * Biomedical research * Biomedical engineering * Bioengineering * Biotechnology Biomedical technologies: * Cloning Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by i ...

World War II
World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks in World War II, Tanks and Air warfare of World War II, aircraft played major roles, enabling the strategic bombing of cities and delivery of the Atomic bombings of Hiroshima and Nagasaki, first and only nuclear weapons ever used in war. World War II is the List of wars by death toll, deadliest conflict in history, causing World War II casualties, the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Allied-occupied Germany, Germany, Allied-occupied Austria, Austria, Occupation of Japan, Japan, a ...

Thirty Years' War
The Thirty Years' War, fought primarily in Central Europe between 1618 and 1648, was one of the most destructive conflicts in History of Europe, European history. An estimated 4.5 to 8 million soldiers and civilians died from battle, famine, or disease, while parts of Germany reported population declines of over 50%. Related conflicts include the Eighty Years' War, the War of the Mantuan Succession, the Franco-Spanish War (1635–1659), Franco-Spanish War, the Torstenson War, the Dutch-Portuguese War, and the Portuguese Restoration War. The war had its origins in the 16th-century Reformation, which led to religious conflict within the Holy Roman Empire. The 1555 Peace of Augsburg attempted to resolve this by dividing the Empire into Catholic and Lutheran states, but the settlement was destabilised by the subsequent expansion of Protestantism beyond these boundaries. Combined with differences over the limits of imperial authority, religion was thus an important factor in star ...

Hanseatic League
The Hanseatic League was a Middle Ages, medieval commercial and defensive network of merchant guilds and market towns in Central Europe, Central and Northern Europe, Northern Europe. Growing from a few Northern Germany, North German towns in the late 12th century, the League expanded between the 13th and 15th centuries and ultimately encompassed nearly 200 settlements across eight modern-day countries, ranging from Tallinn in Estonia in the east, Bergen (Bjørgvin) in Norway to the North to the Netherlands in the west, and extended inland as far as Cologne, Prussia (region), the Prussian regions and Kraków, Poland. The League began as a collection of loosely associated groups of German traders and towns aiming to expand their commercial interests, including protection against robbery. Over time, these arrangements evolved into the League, offering traders toll privileges and protection on affiliated territory and trade routes. Economic interdependence and familial connections am ...
