AAA 400 Drive for Autism
The AAA 400 Drive for Autism is a 400-mile (640 km) Monster Energy NASCAR Cup Series stock car race held annually at Dover International Speedway in Dover, Delaware, the other one being the Dover 400, the fall race at Dover, for the NASCAR Chase for the Championship, it is the first of two Monster Energy NASCAR Cup Series races at Dover. The 2007 Autism Speaks 400 presented by Visa marked the first time that a NASCAR Cup race entitlement was dedicated to a non-profit organization, by the race's title sponsor, Visa Inc. Starting in 2007 through 2017, Dover International Speedway announced that the 2007 race would be named the “Autism Speaks 400 presented by Visa" , dedicating to increasing understanding and knowledge of autism spectrum disorders; to funding dedicated to eugenics; and to advocating for the needs of affected families. Between 2001 and 2006, the race was broadcast in the United States on FX. Television coverage of the race moved to the Fox network beginning in 2007, but after eight years, the race returned to cable television with Fox Sports 1.

Status Dynamic Psychotherapy
Status dynamic psychotherapy (SDT) is an approach to psychotherapy that was created by Peter G. Ossorio at the University of Colorado in the late 1960s as part of a larger system known as "descriptive psychology". Its distinguishing characteristic is that it does not focus on the factors traditionally targeted by psychotherapy such as the client’s behaviors, cognitions, insight into unconscious factors, and patterns of interaction with significant others. Instead, it focuses on bringing about changes in clients’ statuses; i.e., the positions that they occupy in relation to everything in their worlds, including themselves and aspects of themselves. Proponents of SDT maintain:

Tracheophyta
Vascular plants (from la vasculum 'duct'), also called tracheophytes (/trəˈkiː.əˌfaɪts/) or collectively Tracheophyta (from grc τραχεῖα ἀρτηρία (trakheîa artēría) 'windpipe', and φυτά (phutá) 'plants'), form a large group of land plants (c. 300,000 accepted known species) that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). Scientific names for the group include Tracheophyta,:251 Tracheobionta and Equisetopsida sensu lato. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "higher plants," as it was believed that they were further evolved than other plants due to being more complex organisms. However, this is an antiquated remnant of the obsolete scala naturae, and the term is generally considered to be unscientific.

Gastropoda
The gastropods (/ˈɡæstrəpɒdz/), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (/ɡæsˈtrɒpədə/). This class comprises snails and slugs from saltwater, from freshwater, and from the land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. (As of 2017), 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species. The anatomy, behavior, feeding, and reproductive adaptations of gastropods vary significantly from one clade or group to another, so stating many generalities for all gastropods is difficult. The class Gastropoda has an extraordinary diversification of habitats. Representatives live in gardens, woodland, deserts, and on mountains; in small ditches, great rivers, and lakes; in estuaries, mudflats, the rocky intertidal, the sandy subtidal, the abyssal depths of the oceans, including the hydrothermal vents, and numerous other ecological niches, including parasitic ones. Although the name "snail" can be, and often is, applied to all the members of this class, commonly this word means only those species with an external shell big enough that the soft parts can withdraw completely into it. Those gastropods without a shell, and those with only a very reduced or internal shell, are usually known as slugs; those with a shell into which they can partly but not completely withdraw are termed semislugs. The marine shelled species of gastropods include species such as abalone, conches, periwinkles, whelks, and numerous other sea snails that produce seashells that are coiled in the adult stage—though in some, the coiling may not be very visible, for example in cowries. In a number of families of species, such as all the various limpets, the shell is coiled only in the larval stage, and is a simple conical structure after that.

Bahá'í Faith and Science
A fundamental principle of the Bahá'í Faith is the stated harmony of religion and science. Whilst Bahá'í scripture asserts that true science and true religion can never be in conflict, critics argue that statements by the founders clearly contradict current scientific understanding. `Abdu'l-Bahá, the son of the founder of the religion, stated that "when a religion is opposed to science it becomes mere superstition". He also said that true religion must conform to the conclusions of science. This latter aspect of the principle seems to suggest that the religion must always accept current scientific knowledge as authoritative, but some Bahá'í scholars have suggested that this is not always the case. On some issues, the Bahá'í Faith subordinates the conclusions of current scientific thought to its own teachings, which the religion takes as fundamentally true. This is because, in the Bahá'í understanding the present scientific view is not always correct, neither is truth said to be only limited to what science can explain. Instead, in the Bahá'í view, knowledge must be obtained through the interaction of the insights obtained from revelation from God and through scientific investigation.

Action for Climate Empowerment (ACE)
Action for Climate Empowerment (ACE) is a term adopted by the United Nations Framework Convention on Climate Change (UNFCCC). It refers to Article 6 of the Convention’s original text (1992), focusing on six priority areas: education, training, public awareness, public participation, public access to information, and international cooperation on these issues. The implementation of all six areas has been identified as the pivotal factor for everyone to understand and participate in solving the complex challenges presented by climate change. The importance of ACE is reflected in other international frameworks such as the Sustainable Development Goals (SDGs, 2015); the Global Action Programme for Education for Sustainable Development (GAP on ESD, 2014); the Aarhus Convention (2011); and the Bali Guidelines (2010). ACE calls on governments to develop and implement educational and public awareness programmes, train scientific, technical and managerial personnel, foster access to information, and promote public participation in addressing climate change and its effects. It also urges countries to cooperate in this process, by exchanging good practices and lessons learned, and strengthening national institutions. This wide scope of activities is guided by specific objectives that, together, are seen as crucial for effectively implementing climate adaptation and mitigation actions, and for achieving the ultimate objective of the UNFCCC.

Royal Ordnance L7
The Royal Ordnance L7 is the basic model of the United Kingdom 's most successful tank gun. The L7 is a 105 mm L/52 rifled design by the Royal Ordnance Factories intended for use in armoured fighting vehicles, replacing the earlier 20-pounder (84 mm) tank gun mounted on the Centurion tank. The successful L7 gun has been fitted on many armored vehicles including the British Centurion (starting from the Mk. 5/2 variant), the German Leopard 1 and early variants of the US M1 Abrams (M1 and M1IP). The L7 is a popular weapon and continued in use even after it was superseded by the L11 series 120 mm rifled tank gun, for some Centurion tanks operating as Artillery Forward Observation and Armoured Vehicle, Royal Engineers (AVRE) vehicles. The L7, and adaptations of it, can be found as standard or retrofitted equipment on a wide variety of tanks developed during the Cold War.

Lake Taupo
Lake Taupo, often spelled Taupō, is a lake in the North Island of New Zealand. It is in the caldera of the Taupo Volcano. The lake is the namesake of the town of Taupō, which sits on a bay in the lake's north-eastern shore. With a surface area of 616 square kilometres (238 sq mi), it is the largest lake by surface area in New Zealand, and the second largest freshwater lake by surface area in geopolitical Oceania after Lake Murray in Papua New Guinea. Motutaiko Island lies in the south east area of the lake. Lake Taupo has a perimeter of approximately 193 kilometres and a maximum depth of 186 metres. It is drained by the Waikato River (New Zealand's longest river), and its main tributaries are the Waitahanui River, the Tongariro River, and the Tauranga Taupo River. It is a noted trout fishery with stocks of introduced brown and rainbow trout. The level of the lake is controlled by Mercury Energy, the owner of the eight hydroelectric dams on the Waikato River downstream of Lake Taupo, using gates built in 1940–41. The gates are used to reduce flooding, conserve water and ensure a minimum flow of 50 m3/s (1,800 cu ft/s) in the Waikato River. The resource consent allows the level of the lake to be varied between 355.85 and 357.25 metres (1,167.5 and 1,172.1 ft) above sea level.
