Diving is the sport of jumping or falling into water from a platform or springboard, usually while performing acrobatics. Diving is an internationally recognized sport that is part of the Olympic Games. In addition, unstructured and non-competitive diving is a recreational pastime.
Decompression sickness is a medical condition caused by dissolved gases emerging from solution as bubbles inside the body tissues during decompression. DCS most commonly occurs during or soon after a decompression ascent from underwater diving, but can also result from other causes of depressurisation, such as emerging from a caisson, decompression from saturation, flying in an unpressurised aircraft at high altitude, and extravehicular activity from spacecraft. DCS and arterial gas embolism are collectively referred to as decompression illness.
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae.
A diving support vessel is a ship that is used as a floating base for professional diving projects. Basic requirements are the ability to keep station accurately and reliably throughout a diving operation, often in close proximity to drilling or production platforms, for positioning to degrade slowly enough in deteriorating conditions to recover divers without excessive risk, and to carry the necessary support equipment for the mode of diving to be used.
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives.
Noctuoidea is the superfamily of noctuid or "owlet" moths, and has more than 70,000 described species, the largest number of for any Lepidopteran superfamily. Its classification has not yet reached a satisfactory or stable state. Since the end of the 20th century, increasing availability of molecular phylogenetic data for this hugely successful radiation has led to several competing proposals for a taxonomic arrangement that correctly represents the relationships between the major lineages.
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving, an ambiguous term with several possible meanings, depending on context. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well-adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done.
The Bronzen Adhemar is the official Flemish Community Cultural Prize for Comics, given to a Flemish comics author for his body of work. It is awarded by the Flemish Ministry of Culture during Strip Turnhout, the major Flemish comics festival, once every two years.
The Noctuinae are a subfamily of the family Noctuidae, and is composed of moths. The larvae of many species feed on roots or stems of various grasses. Some are generalist feeders which makes them potential pests.
Plusiinae is a smallish subfamily of the moth family Noctuidae. As the Noctuidae appear to be a paraphyletic assemblage, the Plusiinae may eventually be raised to family status.
Hadeninae was formerly a subfamily of the moth family Noctuidae, but was merged into the subfamily Noctuinae. The tribes Apameini, Caradrinini, Elaphriini, Episemini, Eriopygini, Hadenini, Leucaniini, Orthosiini, and Xylenini were moved from Hadeninae to Noctuinae.
Homoglaea is a genus of moths of the family Noctuidae.
Panchrysia is a genus of moths of the family Noctuidae.
Panchrysia v-argenteum is a moth of the family Noctuidae. It is found in the Carpathian mountains, Dalmatia, the Alps and Greece. The species is found high altitudes of up to 1,400 meters.
The Erebidae are a family of moths in the superfamily Noctuoidea. The family is among the largest families of moths by species count and contains a wide variety of well-known macromoth groups. The family includes the underwings (Catocala); litter moths (Herminiinae); tiger, lichen, and wasp moths (Arctiinae); tussock moths (Lymantriinae), including the arctic woolly bear moth ; piercing moths ; micronoctuoid moths (Micronoctuini); snout moths (Hypeninae); and zales, though many of these common names can also refer to moths outside the Erebidae. Some of the erebid moths are called owlets.
The Erebinae are a subfamily of moths in the family Erebidae erected by William Elford Leach in 1815. Erebine moths are found on all continents except Antarctica, but reach their greatest diversity in the tropics. While the exact number of species belonging to the Erebinae is not known, the subfamily is estimated to include around 10,000 species. Some well-known Erebinae include underwing moths (Catocala) and witch moths (Thermesiini). Many of the species in the subfamily have medium to large wingspans, up to nearly 30 cm in the white witch moth, which has the widest wingspan of all Lepidoptera. Erebine caterpillars feed on a broad range of plants; many species feed on grasses and legumes, and a few are pests of castor bean, sugarcane, rice, as well as pistachios and blackberries.
Panchrysia ornata is a species of moth of the family Noctuidae. It is found from the Ural Mountains, through Siberia, Mongolia, Sikhote-Alin and the Paektu Mountains to Kamchatka and the Pacific coast. It is found up to altitudes of 2,400 meters.
Panchrysia aurea is a moth of the family Noctuidae. It is found in southern Europe and western and central Asia. The range extends from Portugal, east to Tian Shan, the Altai and the north-western Himalayas. In central Europe, it is found in the southern Alps, lower Austria and the mountains on the Balkan Peninsula.
Homoglaea dives is a species of cutworm or dart moth in the family Noctuidae. It is found in North America.
