M-class Cruiser
The M-class cruisers were a class of light cruisers planned, but never built, by Nazi Germany's ''Kriegsmarine'' before World War II. The ships were designed for commerce raiding in the Atlantic Ocean. The design for the first four ships suffered from a number of problems, and so the fifth and sixth ships were substantially redesigned. The name of the class is taken from the letter designating the first projected unit. As long as the ships were not named, they were referred to by letters assigned in the chronological order of their planned construction. The first planned unit would have been the thirteenth German cruiser and was therefore listed as ''cruiser M'' in the navy's documents. Had any of the ships been built, the class would have been named after the first completed unit. Development and cancellation In the early 1930s, Adolf Hitler began a rearmament program in Germany. He signed the Anglo-German Naval Agreement in 1935, which allowed Germany to build up its na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz M-Class
Mercedes-Benz (), commonly referred to as Mercedes and sometimes as Benz, is a German luxury and commercial vehicle automotive brand established in 1926. Mercedes-Benz AG (a Mercedes-Benz Group subsidiary established in 2019) is headquartered in Stuttgart, Baden-Württemberg, Germany. Mercedes-Benz AG produces consumer luxury vehicles and commercial vehicles badged as Mercedes-Benz. From November 2019 onwards, Mercedes-Benz-badged heavy commercial vehicles (trucks and buses) are managed by Daimler Truck, a former part of the Mercedes-Benz Group turned into an independent company in late 2021. In 2018, Mercedes-Benz was the largest brand of premium vehicles in the world, having sold 2.31 million passenger cars. The brand's origins lie in Daimler-Motoren-Gesellschaft's 1901 Mercedes and Carl Benz's 1886 Benz Patent-Motorwagen, which is widely regarded as the first internal combustion engine in a self-propelled automobile. The slogan for the brand is "the best or nothing". H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Flare
A solar flare is an intense localized eruption of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle. Solar flares are thought to occur when stored magnetic energy in the Sun's atmosphere accelerates charged particles in the surrounding plasma. This results in the emission of electromagnetic radiation across the electromagnetic spectrum. High-energy electromagnetic radiation from solar flares is absorbed by the daylight side of Earth's upper atmosphere, in particular the ionosphere, and does not reach the surface. This absorption can temporarily increase the ionization of the ionosphere which may interfere with short-wave radio communication. The prediction of solar flares is an active area of research. Flares also occur on other stars, where the term ''stellar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stellar Classification
In astronomy, stellar classification is the classification of stars based on their stellar spectrum, spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a Prism (optics), prism or diffraction grating into a spectrum exhibiting the Continuum (spectrum), rainbow of colors interspersed with spectral lines. Each line indicates a particular chemical element or molecule, with the line strength indicating the abundance of that element. The strengths of the different spectral lines vary mainly due to the temperature of the photosphere, although in some cases there are true abundance differences. The ''spectral class'' of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere's temperature. Most stars are currently classified under the Morgan–Keenan (MK) system using the letters ''O'', ''B'', ''A'', ''F'', ''G'', ''K'', and ''M'', a sequence from the hottest (''O'' type) to the coo ...

Victorian Railways M Class (diesel-hydraulic)
The Victorian Railways M class are a diesel-hydraulic powered railway shunting locomotive, based at the Newport workshops of the Victorian Railways in Victoria, Australia. For a period of time the VR had been using old steam locomotives that were past their best to shunt at their Newport workshops, and decided to construct two small shunting locomotives for use at their workshop facilities. Built by the Victorian Railways themselves, with a Diesel-hydraulic transmission powered by an EMD power unit, the two engines were given class M and the numbers were 231 and 232. After one trialled at Mildura Mildura is a regional city in north-west Victoria, Australia. Located on the Victorian side of the Murray River, Mildura had a population of 34,565 in 2021.

Victorian Railways M Class
The Victorian Railways M class were 4-4-0T (tank) steam locomotives for suburban passenger service in Melbourne, a pattern engine being supplied in 1879 by Beyer, Peacock & Co. Twenty-one further locomotives of this model were built by the Phoenix Foundry of Ballarat, in three batches, from 1884 to 1886. They were numbered 40 (pattern engine), 210-240 (even numbers only), and 312-320 (evens only), and were classed M in 1886. Because their relatively small coal bunker proved inadequate for the rapidly expanding suburban network of the 1880s, they were rebuilt between 1901 and 1905 at the Newport Workshops as 4-4-2T locomotives. They were given an enlarged bunker of capacity on extended frames supported by a trailing radial axle, and the cylinder diameter was increased from . At the same time, the opportunity was taken to replace the troublesome leading Bissell truck with one of the design being used successfully on the contemporary 'New' A and D class locomotives.

Pennsylvania Railroad Class M1
The M1 was a class of steam locomotive of the Pennsylvania Railroad (PRR). It was a class of heavy mixed-traffic locomotives of the 4-8-2 "Mountain" arrangement, which uses four pairs of driving wheels with a four-wheel guiding truck in front for stability at speed and a two-wheel trailing truck to support the large firebox needed for sustained power. Although built for both passenger and freight work, they spent most of their service lives hauling heavy high-speed freight trains. Many PRR men counted the M1 class locomotives as the best steam locomotives the railroad ever owned. History A single prototype, #6699, was built in 1923 at the railroad's Altoona Works. It spent three years in testing, including all kinds of main line service as well as a session on the railroad's static test plant. Having received favorable reports, a further 200 were ordered from commercial locomotive builders; 175 from the Baldwin Locomotive Works and 25 from Lima Locomotive Works. Breaking ...

M-segment
M-segment is the Euro Car Segment, European segments for passenger cars described as "multi purpose vehicles". It covers multi-purpose vehicles, minivans and cargo vans. The minivans (also called MPVs or passenger vans) often have removable rear seating to provide flexibility for transporting passengers or cargo, while the cargo vans (also called light commercial vehicles) are primarily designed for transporting cargo and therefore do not have rear seats. In the recent past, the M-segment was increasing in volume year over year in Europe; in 2015, it is consolidated as the fourth most popular segment (11.5% of the overall market after C-segment, J-segment and B-segment). Multi-purpose vehicles (MPVs) Small MPVs As of 2018, the five highest selling small MPVs in Europe were the Fiat 500L, Ford B-Max, Hyundai ix20, Opel/Vauxhall Meriva and Kia Venga.

United States M-class Submarine
USS ''M-1'' (SS-47) was a unique submarine of the United States Navy. ''M-1'' was designed as a test bed for the newest technology in submarine construction and design. As well as being the world's first double-hulled design (in contrast to Simon Lake's and Holland's single-hulled concepts), her battery was of a new design and was to have solved some of the past flaws. While no other M-class submarines were built, the lessons learned were incorporated into the following . Design ''M-1'' was built with the same armament and range as the preceding L class, but larger due to the double hull design. This was to reduce the risk of battle damage puncturing the pressure hull, and to provide additional reserve buoyancy in the event of flooding.Gardiner, p. 129 The partially retractable /23 caliber deck gun designed for submarines and intended for incorporation in the L class was installed on ''M-1'' prior to installation on any of the L class.
