Artois

Artois (, ; Artesië; Picard: Artoé; English adjective: Artesian) is a region of northern France. Its territory covers an area of about 4,000 km2 and it has a population of about one million. Its principal cities include Arras (Dutch: Atrecht), Saint-Omer, Lens, and Béthune. It is the eponym for the term Artesian.

Location
Artois occupies the interior of the Pas-de-Calais département, the western part of which constitutes the former Boulonnais. Artois roughly corresponds to the arrondissements of Arras, Béthune, Saint Omer, and Lens, and the eastern part of the arrondissement of Montreuil. It occupies the western end of the coalfield which stretches eastward through the neighbouring Nord département and across central Belgium.

History

Originally a feudal county itself, Artois was annexed by the county of Flanders. It came to France in 1180 as a dowry of a Flemish princess, Isabelle of Hainaut, and was again made a separate county in 1237 for Robert, a grandson of Isabelle. Through inheritance, Artois came under the rule of the dukes of Burgundy in 1384. At the death of the fourth duke, Charles the Bold, Artois was inherited by the Habsburgs and passed to the dynasty's Spanish line. After the religious revolts of 1566 in the Netherlands, Artois briefly entered the Dutch Revolt in 1576, participating in the Pacification of Ghent until it formed the Union of Atrecht in 1579.

After the Union of Atrecht, Artois and Hainaut (Dutch: Henegouwen) reached a separate agreement with Philip II. Artois remained with the Spanish Netherlands until it was conquered by France during the Franco-Spanish War. The annexation was acknowledged during the Treaty of the Pyrenees in 1659, and it became a French province. Artois had already been largely French-speaking, but it was part of the Southern Netherlands until the French annexation.

Artois experienced rapid industrial development during the second half of the 19th century, fueled by its rich coal resources. During World War I, the front line between the opposing Central Powers and Allied armies in France ran through the province, resulting in enormous physical damage. Since the second half of the 20th century, Artois has suffered along with nearby areas because of the decline of the coal industry.

List of Anuran families

This list of Anuran families shows all extant families of Anura. Anura is an order of animals in the class Amphibia that includes frogs and toads. More than 5,000 species are described in the order. The living anurans are typically divided into three suborders: Archaeobatrachia, Mesobatrachia, and Neobatrachia. This classification is based on such morphological features as the number of vertebrae, the structure of the pectoral girdle, and the morphology of tadpoles.

Taxonomy
The archaeobatrachians are the most primitive of frogs. These frogs have morphological characteristics which are found mostly in extinct frogs, and are absent in most of the modern frog species. Most of these characteristics are not common between all the families of Archaeobatrachia, or are not absent from all the modern species of frogs. However, all archaeobatrachians have free vertebrae, whereas all other species of frogs have their ribs fused to their vertebrae.

The Neobatrachia comprise the most modern species of frogs. Most of these frogs have morphological features which are more complex than those of the mesobatrachians and archaeobatrachians. The neobatrachians all have a palatine bone, which braces the upper jaw to the neurocranium. This is absent in all Archaeobatrachia and some Mesobatrachia. The third distal carpus is fused with the remaining carpal bones. The adductor longus muscle is present in the neobatrachians, but absent in the archaeobatrachians and some mesobatrachians. It is believed to have differentiated from pectineus muscle, and this differentiation has not occurred in the primitive frogs.

The Mesobatrachia are considered the evolutionary link between the Archaeobatrachia and the Neobatrachia. The families within the mesobatrachian suborder generally contain morphological features typical of both the other suborders. For example, the palatine bone is absent in all archaeobatrachians, and present in all neobatrachians. However, within the mesobatrachians families, it can be dependent on the species as to whether the palatine bone is present.

Due to the many morphological features which separate the frogs, many different systems are used for the classification of the anuran suborders. These different classification systems usually split the Mesobatrachia suborder.

Drummer

A drummer is a percussionist who creates music using drums.

Most contemporary western bands that play rock, pop, jazz, or R&B music include a drummer for purposes including timekeeping and embellishing the musical timbre. The drummer's equipment includes a drum kit (or "drum set" or "trap set"), which includes various drums, cymbals and an assortment of accessory hardware such as pedals, standing support mechanisms, and drum sticks.

Particularly in the traditional music of many countries, drummers use individual drums of various sizes and designs rather than drum kits. Some use only their hands to strike the drums.

In larger ensembles, the drummer may be part of a rhythm section with other percussionists playing. These musicians provide the timing and rhythmic foundation which allow the players of melodic instruments, including voices, to coordinate their musical performance.

Some famous drummers include: Max Roach, Ringo Starr (the Beatles), John Bonham (Led Zeppelin), Ginger Baker (Cream), Keith Moon (the Who), Neil Peart (Rush), Buddy Rich, Gene Krupa, Tony Williams, Elvin Jones, Sheila E, Brian Blade, Jack DeJohnette, Tim "Herb" Alexander (Primus), Phil Rudd (AC/DC), Roger Taylor (Queen), Charlie Watts (the Rolling Stones), Nick Mason (Pink Floyd), Bill Ward (Black Sabbath), Chad Smith (Red Hot Chili Peppers), Travis Barker (Blink-182), Phil Collins (Genesis), Rick Allen (Def Leppard), Alex Van Halen (Van Halen), Tré Cool (Green Day), Dave Grohl (Nirvana), Joey Jordison (Slipknot), Lars Ulrich (Metallica), Tommy Lee (Mötley Crüe), James “The Rev” Sullivan (Avenged Sevenfold) and Cesar Zuiderwijk (Golden Earring).

As well as the primary rhythmic function, in some musical styles, such as world, jazz, classical, and electronica, the drummer is called upon to provide solo and lead performances, at times when the main feature of the music is the rhythmic development. Drummers tend to possess considerable stamina and hands-eyes-legs coordination.

There are many tools that a drummer can use for either timekeeping or soloing. These include cymbals (china, crash, ride, splash, hi-hats, etc.), snare, toms, auxiliary percussion (bells, Latin drums, cowbells, temple blocks) and many others. There are also single, double, and triple bass pedals that drummers may use for the bass drum.

Military
Before motorized transport became widespread, drummers played a key role in military conflicts. Military drummers provided drum cadences that set a steady marching pace and elevated troop morale on the battlefield. In some armies drums also assisted in combat by keeping cadence for firing and loading drills with muzzle loading guns. Military drummers were also employed on the parade field, when troops passed in review, and in various ceremonies including ominous drum rolls accompanying disciplinary punishments. Children also served as drummer boys well into the nineteenth century, though less commonly than is popularly assumed; due to the nature of the job, experienced older men were preferred.

In modern times, drummers are not employed in battle, but their ceremonial duties continue. Typically buglers and drummers mass under a sergeant-drummer and during marches alternately perform with the regiment or battalion ensembles.

Military-based musical percussion traditions were not limited exclusively to the western world. When Emir Osman I was appointed commander of the Turkish army on the Byzantine border in the late 13th century, he was symbolically installed via a handover of musical instruments by the Seldjuk sultan. In the Ottoman Empire, the size of a military band reflected the rank of its commander in chief: the largest band was reserved for the Sultan (viz. his Grand Vizier when taking the field). It included various percussion instruments, often adopted in European military music (as 'Janissary music'). The pitched bass drum is still known in some languages as the Turkish Drum.

Military drumming is the origin of Traditional grip as opposed to Matched grip of drumsticks.

Parades
The drumline is a type of marching ensemble descended from military drummers, and can be arranged as a performance of a drum, a group of drummers, or as a part of a larger marching band. Their uniforms will often have a military style and a fancy hat. In recent times, it is more common to see drummers in parades wearing costumes with an African, Asian, Latin, Native American, or tribal look and sound.

Cultural drumming
Various indigenous cultures use the drum to create a sense of unity with others especially during recreational events. The drum also helps in prayers and meditations.

Genus

Genus ( : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

 * E.g. Panthera leo (lion) and Panthera onca (jaguar) are two species within the genus Panthera. Panthera is a genus within the family Felidae.

The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful:
 * 1) monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstrate both monophyly and validity as a separate lineage).
 * 2) reasonable compactness – a genus should not be expanded needlessly.
 * 3) distinctness – with respect to evolutionarily relevant criteria, i.e. ecology, morphology, or biogeography; DNA sequences are a consequence rather than a condition of diverging evolutionary lineages except in cases where they directly inhibit gene flow (e.g. postzygotic barriers).

Moreover, genera should be composed of phylogenetic units of the same kind as other (analogous) genera.

Etymology
The term "genus" comes from Latin, a noun form cognate with gignere ('to bear; to give birth to'). The Swedish taxonomist Carl Linnaeus popularized its use in his 1753 Species Plantarum, but the French botanist Joseph Pitton de Tournefort (1656–1708) is considered "the founder of the modern concept of genera".

Use
The scientific name (or the scientific epithet) of a genus is also called the generic name; in modern style guides and science, it is always capitalised. It plays a fundamental role in binomial nomenclature, the system of naming organisms, where it is combined with the scientific name of a species: see Botanical name and Specific name (zoology).

Use in nomenclature
The rules for the scientific names of organisms are laid down in the nomenclature codes, which allow each species a single unique name that, for animals (including protists), plants (also including algae and fungi) and prokaryotes (bacteria and archaea), is Latin and binomial in form; this contrasts with common or vernacular names, which are non-standardized, can be non-unique, and typically also vary by country and language of usage.

Except for viruses, the standard format for a species name comprises the generic name, indicating the genus to which the species belongs, followed by the specific epithet, which (within that genus) is unique to the species. For example, the gray wolf's scientific name is Canis lupus, with Canis (Latin for 'dog') being the generic name shared by the wolf's close relatives and lupus (Latin for 'wolf') being the specific name particular to the wolf. A botanical example would be Hibiscus arnottianus, a particular species of the genus Hibiscus native to Hawaii. The specific name is written in lower-case and may be followed by subspecies names in zoology or a variety of infraspecific names in botany.

When the generic name is already known from context, it may be shortened to its initial letter, for example, C. lupus in place of Canis lupus. Where species are further subdivided, the generic name (or its abbreviated form) still forms the leading portion of the scientific name, for example, Canis lupus lupus for the Eurasian wolf subspecies, or as a botanical example, Hibiscus arnottianus ssp. immaculatus. Also, as visible in the above examples, the Latinised portions of the scientific names of genera and their included species (and infraspecies, where applicable) are, by convention, written in italics.

The scientific names of virus species are descriptive, not binomial in form, and may or may not incorporate an indication of their containing genus; for example, the virus species "Salmonid herpesvirus 1", "Salmonid herpesvirus 2" and "Salmonid herpesvirus 3" are all within the genus Salmonivirus; however, the genus to which the species with the formal names "Everglades virus" and "Ross River virus" are assigned is Alphavirus.

As with scientific names at other ranks, in all groups other than viruses, names of genera may be cited with their authorities, typically in the form "author, year" in zoology, and "standard abbreviated author name" in botany. Thus in the examples above, the genus Canis would be cited in full as "Canis Linnaeus, 1758" (zoological usage), while Hibiscus, also first established by Linnaeus but in 1753, is simply "Hibiscus L." (botanical usage).

The type concept
Each genus should have a designated type, although in practice there is a backlog of older names without one. In zoology, this is the type species, and the generic name is permanently associated with the type specimen of its type species. Should the specimen turn out to be assignable to another genus, the generic name linked to it becomes a junior synonym and the remaining taxa in the former genus need to be reassessed.

Categories of generic name
In zoological usage, taxonomic names, including those of genera, are classified as "available" or "unavailable". Available names are those published in accordance with the International Code of Zoological Nomenclature; the earliest such name for any taxon (for example, a genus) should then be selected as the "valid" (i.e., current or accepted) name for the taxon in question.

Consequently, there will be more available names than valid names at any point in time; which names are currently in use depending on the judgement of taxonomists in either combining taxa described under multiple names, or splitting taxa which may bring available names previously treated as synonyms back into use. "Unavailable" names in zoology comprise names that either were not published according to the provisions of the ICZN Code, e.g., incorrect original or subsequent spellings, names published only in a thesis, and generic names published after 1930 with no type species indicated. According to "Glossary" section of the zoological Code, suppressed names (per published "Opinions" of the International Commission of Zoological Nomenclature) remain available but cannot be used as the valid name for a taxon; however, the names published in suppressed works are made unavailable via the relevant Opinion dealing with the work in question.

In botany, similar concepts exist but with different labels. The botanical equivalent of zoology's "available name" is a validly published name. An invalidly published name is a nomen invalidum or nom. inval.; a rejected name is a nomen rejiciendum or nom. rej.; a later homonym of a validly published name is a nomen illegitimum or nom. illeg.; for a full list refer to the International Code of Nomenclature for algae, fungi, and plants and the work cited above by Hawksworth, 2010. In place of the "valid taxon" in zoology, the nearest equivalent in botany is "correct name" or "current name" which can, again, differ or change with alternative taxonomic treatments or new information that results in previously accepted genera being combined or split.

Prokaryote and virus codes of nomenclature also exist which serve as a reference for designating currently accepted genus names as opposed to others which may be either reduced to synonymy, or, in the case of prokaryotes, relegated to a status of "names without standing in prokaryotic nomenclature".

An available (zoological) or validly published (botanical) name that has been historically applied to a genus but is not regarded as the accepted (current/valid) name for the taxon is termed a synonym; some authors also include unavailable names in lists of synonyms as well as available names, such as misspellings, names previously published without fulfilling all of the requirements of the relevant nomenclatural code, and rejected or suppressed names.

A particular genus name may have zero to many synonyms, the latter case generally if the genus has been known for a long time and redescribed as new by a range of subsequent workers, or if a range of genera previously considered separate taxa have subsequently been consolidated into one. For example, the World Register of Marine Species presently lists 8 genus-level synonyms for the sperm whale genus Physeter Linnaeus, 1758, and 13 for the bivalve genus Pecten O.F. Müller, 1776.

Identical names (homonyms)
Within the same kingdom, one generic name can apply to one genus only. However, many names have been assigned (usually unintentionally) to two or more different genera. For example, the platypus belongs to the genus Ornithorhynchus although George Shaw named it Platypus in 1799 (these two names are thus synonyms). However, the name Platypus had already been given to a group of ambrosia beetles by Johann Friedrich Wilhelm Herbst in 1793. A name that means two different things is a homonym. Since beetles and platypuses are both members of the kingdom Animalia, the name could not be used for both. Johann Friedrich Blumenbach published the replacement name Ornithorhynchus in 1800.

However, a genus in one kingdom is allowed to bear a scientific name that is in use as a generic name (or the name of a taxon in another rank) in a kingdom that is governed by a different nomenclature code. Names with the same form but applying to different taxa are called "homonyms". Although this is discouraged by both the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants, there are some five thousand such names in use in more than one kingdom. For instance, A list of generic homonyms (with their authorities), including both available (validly published) and selected unavailable names, has been compiled by the Interim Register of Marine and Nonmarine Genera (IRMNG).
 * Anura is the name of the order of frogs but also is the name of a non-current genus of plants;
 * Aotus is the generic name of both golden peas and night monkeys;
 * Oenanthe is the generic name of both wheatears and water dropworts;
 * Prunella is the generic name of both accentors and self-heal; and
 * Proboscidea is the order of elephants and the genus of devil's claws.
 * The name of the genus Paramecia (an extinct red alga) is also the plural of the name of the genus Paramecium (which is in the SAR supergroup), which can also lead to confusion.

Use in higher classifications
The type genus forms the base for higher taxonomic ranks, such as the family name Canidae ("Canids") based on Canis. However, this does not typically ascend more than one or two levels: the order to which dogs and wolves belong is Carnivora ("Carnivores").

Numbers of accepted genera
The numbers of either accepted, or all published genus names is not known precisely; Rees et al., 2020 estimate that approximately 310,000 accepted names (valid taxa) may exist, out of a total of c. 520,000 published names (including synonyms) as at end 2019, increasing at some 2,500 published generic names per year. "Official" registers of taxon names at all ranks, including genera, exist for a few groups only such as viruses and prokaryotes, while for others there are compendia with no "official" standing such as Index Fungorum for fungi, Index Nominum Algarum and AlgaeBase for algae, Index Nominum Genericorum and the International Plant Names Index for plants in general, and ferns through angiosperms, respectively, and Nomenclator Zoologicus and the Index to Organism Names for zoological names.

Totals for both "all names" and estimates for "accepted names" as held in the Interim Register of Marine and Nonmarine Genera (IRMNG) are broken down further in the publication by Rees et al., 2020 cited above. The accepted names estimates are as follows, broken down by kingdom:
 * Animalia: 239,093 accepted genus names (± 55,350)
 * Plantae: 28,724 (± 7,721)
 * Fungi: 10,468 (± 182)
 * Chromista: 11,114 (± 1,268)
 * Protozoa: 3,109 (± 1,206)
 * Bacteria: 3,433 (± 115)
 * Archaea: 140 (± 0)
 * Viruses: 851 (± 0)

The cited ranges of uncertainty arise because IRMNG lists "uncertain" names (not researched therein) in addition to known "accepted" names; the values quoted are the mean of "accepted" names alone (all "uncertain" names treated as unaccepted) and "accepted + uncertain" names (all "uncertain" names treated as accepted), with the associated range of uncertainty indicating these two extremes.

Within Animalia, the largest phylum is Arthropoda, with 151,697 ± 33,160 accepted genus names, of which 114,387 ± 27,654 are insects (class Insecta). Within Plantae, Tracheophyta (vascular plants) make up the largest component, with 23,236 ± 5,379 accepted genus names, of which 20,845 ± 4,494 are angiosperms (superclass Angiospermae).

By comparison, the 2018 annual edition of the Catalogue of Life (estimated >90% complete, for extant species in the main) contains currently 175,363 "accepted" genus names for 1,744,204 living and 59,284 extinct species, also including genus names only (no species) for some groups.

Genus size

The number of species in genera varies considerably among taxonomic groups. For instance, among (non-avian) reptiles, which have about 1180 genera, the most (>300) have only 1 species, ~360 have between 2 and 4 species, 260 have 5–10 species, ~200 have 11–50 species, and only 27 genera have more than 50 species. However, some insect genera such as the bee genera Lasioglossum and Andrena have over 1000 species each. The largest flowering plant genus, Astragalus, contains over 3,000 species.

Which species are assigned to a genus is somewhat arbitrary. Although all species within a genus are supposed to be "similar", there are no objective criteria for grouping species into genera. There is much debate among zoologists whether enormous, species-rich genera should be maintained, as it is extremely difficult to come up with identification keys or even character sets that distinguish all species. Hence, many taxonomists argue in favor of breaking down large genera. For instance, the lizard genus Anolis has been suggested to be broken down into 8 or so different genera which would bring its ~400 species to smaller, more manageable subsets.

Aerotherapeutics is the treatment of disease by atmospheric air: a term which of late has come to be used somewhat more loosely to include also pneumotherapeutics, or the treatment of disease by artificially prepared atmospheres.

The physical and chemical properties of atmospheric air, under ordinary pressure or under modified pressure, may be therapeutically utilized either on the external surface of the body, on the respiratory surface, or on both surfaces together. Also modifications may be induced in the ventilation of the lungs by general gymnastics or respiratory gymnastics. The beneficial effects of air under ordinary pressure are now utilized in line open-air treatment of phthisical patients, and the main indications of benefit resulting therefrom are reduction of the fever, improvement of appetite and the induction of sleep. The air, however, may be modified in composition or in temperature. Inhalation is the most common and successful method of applying it--when modified in composition--to the human body.

The methods in use are as follows:
 * 1) Inhalation of gases, as oxygen and nitrous oxide.  The dyspnoea and cyanosis of pneumonia, capillary bronchitis, heart failure, etc., are much relieved by the inhalation of oxygen; and nitrous oxide is largely used as an anaesthetic in minor operations;
 * 2) Certain liquids are used as anaesthetics, which volatilize at low temperatures, as chloroform and ether.
 * 3) Mercury and sulphur, both of which require heat for volatilization, are very largely used.  In a mercurial or sulphur bath, the patient, enveloped in a sheet, sits on a chair beneath which a spirit lamp is placed to vaporize the drug, the best results being obtained when the atmosphere is surcharged with steam at the same time.  The vapour envelops the patient and is absorbed by the skin.  This method is extensively used in the treatment of syphilis, and also for scabies and other parasitic affections of the skin.
 * 4) Moist inhalations are rather losing repute in the light of modern investigations, which tend to show that nothing lower than the larger bronchial tubes is affected.  Complicated apparatus has been devised for the application, although a wide-mouthed jug filled with boiling water, into which the drug is thrown, is almost equally efficacious.

Artificial atmospheres may be made for invalids by respirators which cover the mouth and nose, the air being drawn through tow or sponge, on which is sprinkled the disinfectant to be used. This is most valuable in the intensely offensive breath of some cases of bronchiectasis.

The air may be modified as to temperature. Cold air at 32--33 deg. F. has been used in chronic catarrhal conditions of the lungs, with the result that cough diminishes, the pulse becomes fuller and slower and the general condition improves. The more recent observations of Pasquale di Tullio go far to show that this may be immensely valuable in the treatment of haemoptysis. The inspiration of superheated dry air has been the subject of much investigation, but with very doubtful results.

Hot air applied to the skin is more noteworthy in its therapeutic effects. If a current of hot air is directed upon healthy skin, the latter becomes pale and contracts in consequence of vaso-constriction. But if it is directed on a patch of diseased skin, as in lupus, an inflammatory reaction is set up and the diseased part begins to undergo necrosis. This fact has been used with good results in lupus, otorrhoea, rhinitis and other nasal and laryngeal troubles.

Lastly the air may be either compressed or rarefied. The physiological effects of compressed air were first studied in diving-bells, and more recently in caissons. Caisson workers at first enjoy increased strength, vigour and appetite; later, however, the opposite effect is produced and intenbe debility supervenes. In addition, caisson workers suffer from a series of troubles which are known as accidents of decompression (see Caisson disease and decompression sickness.) But, therapeutically, compressed air has been utilized by means of pneumatic chambers large enough to hold one or more adults at the time, in which the pressure of the atmosphere can be exactly regulated. This form of treatment has been found of much value in the treatment of emphysema, early pulmonary tuberculosis (not in the presence of persistent high temperature, haemorrhage, softening or suppuration), delayed absorption of pleural effusions, heart disease, anaemia and chlorosis. But compressed air is contra-indicated in advanced tubercle, fever, and in diseases of kidneys, liver or intestines.

Rarefied air was used as long ago as 1835, by V. T. Junod, who utilized it for local application by inventing the Junod Boot. By means of this the blood could be drawn into any part to which it was applied, the vessels of which became gorged with blood at the expense of internal organs. More recently this method of treatment has undergone far-reaching developments and is known as the passive hyperaemic treatment.

There are also various forms of apparatus by means of which air at greater or lesser pressures may be drawn into the lungs, and for the performance of lung gymnastics of various kinds. Mr Ketchum of the United States has invented one which is much used. A committee of the Brompton Hospital, London, investigating its capabilities, decided that its use brought about
 * 1) an increase of chest circumference, and
 * 2) in cases of consolidation of the lung a diminution in the area of dulness.
