The Ardhana class is a class of patrol boat that was built for the United Arab Emirates Navy in the early 1970s and commissioned in 1975. As of 2009 all six vessels remain in service, though it has been announced that they will be decommissioned and replaced by the Baynunah-class corvette.

Chordate Phylum of animals having a dorsal nerve cord

A chordate is an animal of the phylum Chordata. All chordates possess 5 synapomorphies, or primary characteristics, at some point during their larval or adulthood stages that distinguish them from all other taxa. These 5 synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. Chordates get their name from their characteristic “notochord”, which plays a significant role in chordate structure and movement. Chordates are also bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit metameric segmentation.

First-class cricket is the highest-standard international or domestic matches in the sport of cricket. A first-class match is one of three or more days' scheduled duration between two sides of eleven players each and is officially adjudged to be worthy of the status by virtue of the standard of the competing teams. Matches must allow for the teams to play two innings each, although in practice a team might play only one innings or none at all.

Proteobacteria Phylum of Gram-negative bacteria

Proteobacteria is a major phylum of Gram-negative bacteria. They include a wide variety of pathogenic genera, such as Escherichia, Salmonella, Vibrio, Helicobacter, Yersinia, Legionellales, and many others. Others are free-living (nonparasitic) and include many of the bacteria responsible for nitrogen fixation.

Stellar classification Classification of stars based on their spectral characteristics

In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the 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.

Lever Simple machine consisting of a beam pivoted at a fixed hinge

A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. Also, leverage is mechanical advantage gained in a system. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever. As such, the lever is a mechanical advantage device, trading off force against movement.The formula for mechanical advantage of a lever is

The Ganda language or Luganda is a Bantu language spoken in the African Great Lakes region. It is one of the major languages in Uganda and is spoken by more than eight million Baganda and other people principally in central Uganda including the capital Kampala of Uganda. Typologically, it is a highly agglutinating, tonal language with subject–verb–object word order and nominative–accusative morphosyntactic alignment.

Corvette Small warship

A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern types of ships below a corvette are coastal patrol craft, missile boat and fast attack craft. In modern terms, a corvette is typically between 500 tons and 2,000 tons, although recent designs may approach 3,000 tons, which might instead be considered a small frigate.

In mathematics, in particular in algebraic topology, differential geometry and algebraic geometry, the Chern classes are characteristic classes associated with complex vector bundles. They have since found applications in physics, Calabi–Yau manifolds, string theory, Chern–Simons theory, knot theory, Gromov–Witten invariants, topological quantum field theory, the Chern theorem etc.

Complexity class Set of problems in computational complexity theory

In computational complexity theory, a complexity class is a set of computational problems of related resource-based complexity. The two most commonly analyzed resources are time and memory.

Pennant number

In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number. Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship.

Smoothness Property measuring how many times a function can be differentiated

In mathematical analysis, the smoothness of a function is a property measured by the number of continuous derivatives it has over some domain. At the very minimum, a function could be considered smooth if it is differentiable everywhere. At the other end, it might also possess derivatives of all orders in its domain, in which case it is said to be infinitely differentiable and referred to as a C-infinity function.

Marxism Economic and sociopolitical worldview based on the works of Karl Marx

Marxism is a method of socioeconomic analysis that uses a materialist interpretation of historical development, better known as historical materialism, to understand class relations and social conflict as well as a dialectical perspective to view social transformation. It originates from the works of 19th-century German philosophers Karl Marx and Friedrich Engels. As Marxism has developed over time into various branches and schools of thought, there is currently no single definitive Marxist theory.
