A crystal or crystalline solid is a solid material whose constituents are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification.
A world cup is a global sporting competition in which the participant entities – usually international teams or individuals representing their countries – compete for the title of world champion. The events most associated with the concept are the FIFA World Cup for association football, along with the ICC Cricket World Cup for cricket, both of which are widely known simply as "the World Cup." However, there are a number of notable popular team sports competitions labeled "world cups", such as the Rugby World Cup, Rugby League World Cup, and the Hockey World Cup.
A sports governing body is a sports organization that has a regulatory or sanctioning function.
In biochemistry, a disulfide refers to a functional group with the structure R−S−S−R′. The linkage is also called an SS-bond or sometimes a disulfide bridge and is usually derived by the coupling of two thiol groups. In biology, disulfide bridges formed between thiol groups in two cysteine residues are an important component of the secondary and tertiary structure of proteins. Persulfide usually refers to R−S−S−H compounds.
A nimbostratus cloud is a multilevel, amorphous, nearly uniform, and often dark-grey cloud that usually produces continuous rain, snow, or sleet, but no lightning or thunder.
The municipalities of Brazil are administrative divisions of the Brazilian states. Brazil currently has 5,570 municipalities, which, given the 2019 population estimate of 210,147,125, makes an average municipality population of 37,728 inhabitants. The average state in Brazil has 214 municipalities. Roraima is the least subdivided state, with 15 municipalities, while Minas Gerais is the most, with 853. Northern states are divided into small numbers of large municipalities, and therefore they cover large areas incorporating several separated cities or towns that do not necessarily conform to one single conurbation. Southern and eastern states on the other hand, are divided into many small municipalities, and therefore large urban areas usually extend over several municipalities which form one single conurbation.
Action fiction is a literary genre that focuses on stories that involve high-stakes, high-energy, and fast-paced events. This genre includes a wide range of subgenres, such as spy novels, adventure stories, tales of terror and intrigue and mysteries. This kind of story utilizes suspense, the tension that is built up when the reader wishes to know how the conflict between the protagonist and antagonist is going to be resolved or what the solution to the puzzle of a thriller is.
A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology. They are formed when part of a headland is eroded by hydraulic action, which is the force of the sea or water crashing against the rock. The force of the water weakens cracks in the headland, causing them to later collapse, forming free-standing stacks and even a small island. Without the constant presence of water, stacks also form when a natural arch collapses under gravity, due to sub-aerial processes like wind erosion. Erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast—the stack. Eventually, erosion will cause the stack to collapse, leaving a stump. Stacks can provide important nesting locations for seabirds, and many are popular for rock climbing.
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless.
A pupa is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence.
In music, form refers to the structure of a musical composition or performance. In his book, Worlds of Music, Jeff Todd Titon suggests that a number of organizational elements may determine the formal structure of a piece of music, such as "the arrangement of musical units of rhythm, melody, and/or harmony that show repetition or variation, the arrangement of the instruments, or the way a symphonic piece is orchestrated", among other factors. It is, "the ways in which a composition is shaped to create a meaningful musical experience for the listener."
Form refers to the largest shape of the composition. Form in music is the result of the interaction of the four structural elements described above [sound, harmony, melody, rhythm]."
The Bachelor of Business Administration (BBA), Bachelor of Science in Business Administration, or Bachelor of Arts in Business Administration is a bachelor's degree in business administration awarded by colleges and universities after completion of four years and typically 120 credits of undergraduate study in the fundamentals of business administration, usually including advanced courses in business analytics, business communication, corporate finance, financial accounting, macroeconomics, management, management accounting, marketing, microeconomics, strategic management, supply chain management, and other key academic subjects associated with the academic discipline of business management.
In biochemistry, a metabolite is an intermediate or end product of metabolism. The term is usually used for small molecules. Metabolites have various functions, including fuel, structure, signaling, stimulatory and inhibitory effects on enzymes, catalytic activity of their own, defense, and interactions with other organisms.
Traditionally, a jersey is an item of knitted clothing, generally made of wool or cotton, with sleeves, worn as a pullover, as it does not open at the front, unlike a cardigan. It is usually close-fitting and machine knitted in contrast to a guernsey that is more often hand knit with a thicker yarn. The word is usually used interchangeably with sweater.
In geography, a cape is a headland, or peninsula or promontory extending into a body of water, usually the sea. A cape usually represents a marked change in trend of the coastline, often making them important landmarks in sea navigation. This also makes them prone to natural forms of erosion, mainly tidal actions, resulting in a relatively short geological lifespan. Capes can be formed by glaciers, volcanoes, and changes in sea level. Erosion plays a large role in each of these methods of formation.
A privately held company is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets but rather the company's stock is offered, owned, traded, exchanged privately, or over-the-counter. In the case of a closed corporation, there are relatively few shareholders or company members. Related terms are unquoted company and unlisted company.
The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong bracket systems.
L, or l, is the twelfth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is el, plural els.
A company, abbreviated as co., is a legal entity representing an association of people, whether natural, legal or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Companies take various forms, such as:
In linguistics, a suffix is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns and adjectives, and verb endings, which form the conjugation of verbs. Suffixes can carry grammatical information or lexical information . Inflection changes the grammatical properties of a word within its syntactic category. Derivational suffixes fall into two categories: class-changing derivation and class-maintaining derivation.
