Information: - Research comprises "creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications." It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or develop new theories. A research project may also be an expansion on past work in the field. Research projects can be used to develop further knowledge on a topic, or in the example of a school research project, they can be used to further a student's research prowess to prepare them for future jobs or reports. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, or the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic, social, business, marketing, practitioner research, life, technological,etc. - The term tetrarchy (from the , "tetrarchia", "leadership of four [people]") describes any form of government where power is divided among four individuals, but in modern usage usually refers to the system instituted by Roman Emperor Diocletian in 293, marking the end of the Crisis of the Third Century and the recovery of the Roman Empire. This tetrarchy lasted until c.313, when internecine conflict eliminated most of the claimants to power, leaving Constantine in control of the western half of the empire, and Licinius in control of the eastern half. - Geobiology is a field of scientific research that explores the interactions between the physical Earth and the biosphere. It is a relatively young field, and its borders are fluid. There is considerable overlap with the fields of ecology, evolutionary biology, microbiology, paleontology, and particularly biogeochemistry. Geobiology applies the principles and methods of biology and geology to the study of the ancient history of the co-evolution of life and Earth as well as the role of life in the modern world. Geobiologic studies tend to be focused on microorganisms, and on the role that life plays in altering the chemical and physical environment of the lithosphere, atmosphere, hydrosphere and/or cryosphere. It differs from biogeochemistry in that the focus is on processes and organisms over space and time rather than on global chemical cycles. - Hispan, Espan, Hispalo or Hispano, is a mythological character of Antiquity, who would derive the name Hispania, according to some ancient writers. Therefore, Hispan is the eponymous hero of Hispania. Hispan is mentioned first by the Gallo-Roman historian Gnaeus Pompeius Trogus (1st century BC) in his work "Historiae Philippicae", preserved only in a later summary, probably made in the 3rd century AD by Justinus. During the Middle Ages, Hispan was also known as Espan, told of him various legends. - Lucius Cornelius Bocchus was a Lusitanian from Roman Hispania who wrote about natural history . Ancient authors mention his writings , which are otherwise lost . Pliny the Elder provides an excerpt from the chronicle of Cornelius Bocchus and mentions him as one of his sources . - Tin is a chemical element with the symbolSn (for ) and atomic number50, is a post-transition metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide, SnO. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table, thanks to its magic number of protons. It has two main allotropes: at room temperature, the stable allotrope is -tin, a silvery-white, malleable metal, but at low temperatures it transforms into the less dense grey -tin, which has the diamond cubic structure. Metallic tin is not easily oxidized in air. - Vespasian ( ; 17 November AD 9 23 June AD 79) was Roman emperor from AD 69 to AD 79. Vespasian founded the Flavian dynasty that ruled the Empire for twenty-seven years. Vespasian was from an equestrian family that rose into the senatorial rank under the JulioClaudian emperors. Although he fulfilled the standard succession of public offices and held the consulship in AD 51, Vespasian's renown came from his military success: he was legate of Legio II "Augusta" during the Roman invasion of Britain in 43 and subjugated Judaea during the Jewish rebellion of 66. - Gaius Plinius Secundus (AD 23 August 25, AD 79), better known as Pliny the Elder, was a Roman author, naturalist, and natural philosopher, as well as naval and army commander of the early Roman Empire, and personal friend of the emperor Vespasian. - Natural history is the research and study of organisms including animals, fungi and plants in their environment, leaning more towards observational than experimental methods of study. It encompasses scientific research but is not limited to it, with articles nowadays more often published in science magazines than in academic journals. Grouped among the natural sciences, natural history is the systematic study of any category of natural objects or organisms. That is a very broad designation in a world filled with many narrowly focused disciplines. So while natural history dates historically from studies in the ancient Greco-Roman world and the mediaeval Arabic world, through to European Renaissance naturalists working in near isolation, today's field is more of a cross discipline umbrella of many specialty sciences. For example, geobiology has a strong multi-disciplinary nature combining scientists and scientific knowledge of many specialty sciences. - Arabic (' or ' ) is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the "lingua franca" of the Arab world. Arabic also is a liturgical language of 1.7 billion Muslims. It is one of six official languages of the United Nations. It is named after the Arabs, a term initially used to describe peoples living from Mesopotamia in the east to the Anti-Lebanon mountains in the west, and from northwestern Arabia to the Sinai in the south. - Constrained Energy Lapped Transform (CELT) is an open, royalty-free lossy audio compression format and a free software codec with especially low algorithmic delay for use in low-latency audio communication. The algorithms are openly documented and may be used free of software patent restrictions. Development of the format was maintained by the Xiph.Org Foundation (as part of the Ogg codec family) and later coordinated by the Opus working group of the Internet Engineering Task Force (IETF). - Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the recording of data via the use of instruments. The term may also refer to any data collected during the scientific activity. Observations can be qualitative, that is, only the absence or presence of a property is noted, or quantitative if a numerical value is attached to the observed phenomenon by counting or measuring. - Hispania was the Roman name for the Iberian Peninsula. Under the Republic, Hispania was divided into two provinces: Hispania Citerior and Hispania Ulterior. During the Principate, Hispania Ulterior was divided into two new provinces, Baetica and Lusitania, while Hispania Citerior was renamed Tarraconensis. Subsequently, the western part of Tarraconensis was split off, first as Hispania Nova, later renamed Callaecia (or Gallaecia, whence modern Galicia). From Diocletian's Tetrarchy (AD 284) onwards, the south of remaining Tarraconensis was again split off as Carthaginensis, and probably then too the Balearic Islands and all the resulting provinces formed one civil diocese under the "vicarius" for the Hispaniae (that is, the Celtic provinces). The name, Hispania, was also used in the period of Visigothic rule. - An author is narrowly defined as the originator of any written work and can thus also be described as a writer (with any distinction primarily being an implication that an author is a writer of one or more major works, such as books or plays). More broadly defined, an author is "the person who originated or gave existence to anything" and whose authorship determines responsibility for what was created. The more specific phrase published author refers to an author (especially but not necessarily of books) whose work has been independently accepted for publication by a reputable publisher , versus a self-publishing author or an unpublished one . - "For the twelfth-century juris, see Vacarius." Vicarius is a Latin word, meaning "substitute" or "deputy". It is the root of the English word "vicar". - The Greco-Roman world, Greco-Roman culture, or the term Greco-Roman (or ; spelled Graeco-Roman in the United Kingdom and the Commonwealth), when used as an adjective, as understood by modern scholars and writers, refers to those geographical regions and countries that culturally (and so historically) were directly, long-term, and intimately influenced by the language, culture, government and religion of the ancient Greeks and Romans. In exact terms the area refers to the "Mediterranean world", the extensive tracts of land centered on the Mediterranean and Black Sea basins, the "swimming-pool and spa" of the Greeks and Romans, i.e. one wherein the cultural perceptions, ideas and sensitivities of these peoples were dominant. - The Iberian Peninsula , also known as Iberia, is located in the southwest corner of Europe. The peninsula is principally divided between Portugal and Spain, comprising most of their territory. It also includes Andorra and a small part of France along the peninsula's northeastern edge, as well as Gibraltar on its south coast, a small peninsula which forms an overseas territory of the United Kingdom. With an area of approximately , it is the second largest European peninsula, after the Scandinavian.
