Raf.
Constantine Samuel Rafinesque-Schmaltz (; 22 October 178318 September 1840) was a French early 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community and his submissions were automatically rejected by leading journals. Among his theories we ...

Principle Of Priority
Priority is a principle in Taxonomy (biology), biological taxonomy by which a valid scientific name is established based on the oldest available name. It is a decisive rule in Botanical nomenclature, botanical and zoological nomenclature to recognise the first Binomial nomenclature, binomial name (also called ''binominal name'' in zoology) given to an organism as the correct and acceptable name. The purpose is to select one scientific name as a stable one out of two or more alternate names that often exist for a single species. The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) defines it as: "A right to precedence established by the date of valid publication of a legitimate name or of an earlier homonym, or by the date of designation of a type." Basically, it is a scientific procedure to eliminate duplicate or multiple names for a species, for which Lucien Marcus Underwood called it "the principle of outlaw in nomenclature".

Galata
Galata is the former name of the Karaköy neighbourhood in Istanbul, which is located at the northern shore of the Golden Horn. The district is connected to the historic Fatih district by several bridges that cross the Golden Horn, most notably the Galata Bridge. The medieval citadel of Galata was a colony of the Republic of Genoa between 1273 and 1453. The famous Galata Tower was built by the Genoese in 1348 at the northernmost and highest point of the citadel. Galata is now a quarter within the district of Beyoğlu in Istanbul. Etymology There are several theories concerning the origin of the name ''Galata''. The Greeks believe that the name comes either from ''Galatai'' (meaning "Gauls"), as the Celtic tribe of Gauls ( Galatians) were thought to have camped here during the Hellenistic period before settling into Galatia in central Anatolia; or from ''galatas'' (meaning " milkman"), as the area was used by shepherds for grazing in the Early Medieval (Byzantine) pe ...

Mollusc Shell
The mollusc (or mollusk) shell is typically a calcareous exoskeleton which encloses, supports and protects the soft parts of an animal in the phylum Mollusca, which includes snails, clams, tusk shells, and several other classes. Not all shelled molluscs live in the sea; many live on the land and in freshwater. The ancestral mollusc is thought to have had a shell, but this has subsequently been lost or reduced on some families, such as the squid, octopus, and some smaller groups such as the caudofoveata and neomeniomorpha, solenogastres. Today, over 100,000 living species bear a shell; there is some dispute as to whether these shell-bearing molluscs form a monophyletic group (conchifera) or whether shell-less molluscs are interleaved into their family tree. Malacology, the scientific study of molluscs as living organisms, has a branch devoted to the study of shells, and this is called conchology—although these terms used to be, and to a minor extent still are, used interchange ...

Dunbar And Hunter Expedition
The Dunbar and Hunter Expedition, also known as the Grand Expedition, was an expedition led by William Dunbar and Dr. George Hunter with the purpose of exploring the lower portion of the Louisiana Purchase. The expedition was given the orders by U.S. President Thomas Jefferson to explore parts of Mississippi and Missouri. The members of the expedition recorded information about the Ouachita River, and studied things such as the hot springs in present-day Arkansas and provided one of the earliest descriptions of Arkansas and Louisiana. Motivations William Dunbar was a Scottish immigrant and scientist living in Natchez, Mississippi, when Jefferson contacted him about the proposed expedition. Jefferson wanted the expedition to travel through the southern area of the Louisiana Purchase. Specifically, he wanted the expedition to follow the rivers in the area, such as the Red River or the Arkansas River. The other leading member of the expedition, George Hunter, was recruited by ...

Mule Deer At Clearwater Pass 2
The mule is a domestic equine hybrid between a donkey, and a horse. It is the offspring of a male donkey (a jack) and a female horse (a mare). The horse and the donkey are different species, with different numbers of chromosomes; of the two possible first-generation hybrids between them, the mule is easier to obtain and more common than the hinny, which is the offspring of a male horse (a stallion) and a female donkey (a jenny). Mules vary widely in size, and may be of any color seen in horses or donkeys. They are more patient, hardier and longer-lived than horses, and are perceived as less obstinate and more intelligent than donkeys. Terminology A female mule is often called a "molly" or "Molly mule," though the correct term is "mare mule." A male mule is called a "john" or "John mule," though the correct term is "horse mule." A young male mule is called a "mule colt," and a young female is called a "mule filly." The donkey used to produce mules is called a "mule jack, ...

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maidenhair Fern
''Adiantum'' (), the maidenhair fern (not to be confused with the similar-looking maidenhair spleenwort fern), is a genus of about 250 species of ferns in the subfamily Vittarioideae of the family Pteridaceae, though some researchers place it in its own family, Adiantaceae. The genus name comes from Greek, meaning "unwetted", referring to the fronds' ability to shed water without becoming wet. Description They are distinctive in appearance, with dark, often black stipes and rachises, and bright green, often delicately cut leaf tissue. The sori are borne submarginally, and are covered by reflexed flaps of leaf tissue which resemble indusia. Dimorphism between sterile and fertile fronds is generally subtle. They generally prefer humus-rich, moist, well-drained sites, ranging from bottomland soils to vertical rock walls. Many species are especially known for growing on rock walls around waterfalls and water seepage areas. The highest species diversity is in the Andes. Fairly h ...

Self-medication
Self-medication, sometime called do-it-yourself (DIY) medicine, is a human behavior in which an individual uses a substance or any exogenous influence to self-administer treatment for physical or psychological conditions, for example headaches or fatigue. The substances most widely used in self-medication are over-the-counter drugs and dietary supplements, which are used to treat common health issues at home. These do not require a doctor's prescription to obtain and, in some countries, are available in supermarkets and convenience stores. The field of psychology surrounding the use of psychoactive drugs is often specifically in relation to the use of recreational drugs, alcohol, comfort food, and other forms of behavior to alleviate symptoms of mental distress, stress and anxiety, including mental illnesses or psychological trauma. Such treatment may cause serious detriment to physical and mental health if motivated by addictive mechanisms. In postsecondary (university ...
