Crotalus (instrument)
A crotalus ( es, matraca), also known as a crotalum or clapper, is a wooden liturgical rattle or clapper that replaces altar bells during the celebration of the Tridentine Paschal Triduum at the end of Lent in the Catholic Church. It is also occasionally used during the celebration of the Ordinary Form Roman Missal during the Paschal Triduum, but its popularity decreased following the liturgical reforms of the Second Vatican Council. The crotalus is also sometimes used in Episcopal Church parishes. Etymology The Latin word ''crotalus'' (and the less frequently referenced liturgical instrument ''crotalum'') derive from the Ancient Greek '' krotalon'' (κρόταλον). The latter term referred to a type of clapper, rattle, or castanet as used in Ancient Greece and Egypt. Appearance and use Made from wood, the particular style and manner of noise-making varies between different clappers. Some use an integral hammer that strikes the wood, while others use a piece of wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Rattle
Frederick Bowden Rattle (13 August 1869 – 13 August 1950) was an Australian politician. He was born in Hobart and was an accountant and solicitor before entering politics. In 1903 he was elected to the Tasmanian House of Assembly as the member for Glenorchy. With the introduction of proportional representation Proportional representation (PR) refers to a type of electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to geographical (e.g. states, regions) and political divis ... in 1909 he successfully ran for the new seat of Denison as an Anti-Socialist. He left the House in 1912 and died in Hobart in 1950.

Rattle (magazine)
''Rattle'' is a quarterly poetry magazine founded in 1994, published in Los Angeles in the United States. It publishes poems both by established writers, such as Philip Levine, Jane Hirshfield, Billy Collins, Sharon Olds, Gregory Orr, Patricia Smith, and Anis Mojgani, and by new and emerging poets. Poems from the magazine have been reprinted in ''The Best American Poetry'' and Pushcart Prize anthologies. According to the magazine's website, "Rattle ''is pretty simple: We love poetry and feel that it's something everyone can enjoy. We look for poems that are accessible, that have heart, that have something to say.''" Each issue is themed to honour a particular community of poets, such as teachers, slam poets, or, most recently, Los Angeles poets. Interviews with contemporary poets are also a staple. Though primarily dedicated to its print issues, the magazine's website also hosts other material, including audio archives and reviews of contemporary poetry. The ''Rattle'' ...

Rattle GUI
Rattle GUI is a free and open source software ( GNU GPL v2) package providing a graphical user interface (GUI) for data mining using the R statistical programming language. Rattle is used in a variety of situations. Currently there are 15 different government departments in Australia, in addition to various other organisations around the world, which use Rattle in their data mining activities and as a statistical package. Rattle provides considerable data mining functionality by exposing the power of the R Statistical Software through a graphical user interface. Rattle is also used as a teaching facility to learn the R software Language. There is a Log Code tab, which replicates the R code for any activity undertaken in the GUI, which can be copied and pasted. Rattle can be used for statistical analysis, or model generation. Rattle allows for the dataset to be partitioned into training, validation and testing. The dataset can be viewed and edited. There is also an option for sco ...

Constraint Algorithm
In computational chemistry, a constraint algorithm is a method for satisfying the Newtonian motion of a rigid body which consists of mass points. A restraint algorithm is used to ensure that the distance between mass points is maintained. The general steps involved are: (i) choose novel unconstrained coordinates (internal coordinates), (ii) introduce explicit constraint forces, (iii) minimize constraint forces implicitly by the technique of Lagrange multipliers or projection methods. Constraint algorithms are often applied to molecular dynamics simulations. Although such simulations are sometimes performed using internal coordinates that automatically satisfy the bond-length, bond-angle and torsion-angle constraints, simulations may also be performed using explicit or implicit constraint forces for these three constraints. However, explicit constraint forces give rise to inefficiency; more computational power is required to get a trajectory of a given length. Therefore, internal c ...

Rhinanthus
''Rhinanthus'' is a genus of annual hemiparasitic herbaceous plants in the family Orobanchaceae, formerly classified in the family Scrophulariaceae. Its species are commonly known as rattles. The genus consists of about 30 to 40 species found in Europe, northern Asia, and North America, with the greatest species diversity (28 species) in Europe. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using molecular characters. ''Rhinanthus'' is the sister genus to ''Lathraea'', and then to ''Rhynchocorys''. These three genera share phylogenetic affinities with members of the core Rhinantheae: ''Bartsia'', ''Euphrasia'', ''Tozzia'', ''Hedbergia'', '' Bellardia'', and ''Odontites''. ''Melampyrum ''Melampyrum'' is a genus of about 20 species of herbaceous flowering plants in the family Orobanchaceae known commonly as cow wheat. They are native to temperate regions of the Northern Hemisphere. They are hemiparasites on other plants, obtai ...'' appears as a more ...

Gurgling
In fluid mechanics, two-phase flow is a flow of gas and liquid — a particular example of multiphase flow. Two-phase flow can occur in various forms, such as flows transitioning from pure liquid to vapor as a result of external heating, separated flows, and dispersed two-phase flows where one phase is present in the form of particles, droplets, or bubbles in a continuous carrier phase (i.e. gas or liquid). Categorization The widely accepted method to categorize two-phase flows is to consider the velocity of each phase as if there is not other phases available. The parameter is a hypothetical concept called Superficial velocity. Examples and applications Historically, probably the most commonly studied cases of two-phase flow are in large-scale power systems. Coal and gas-fired power stations used very large boilers to produce steam for use in turbines. In such cases, pressurised water is passed through heated pipes and it changes to steam as it moves through the pipe. The d ...

Death Rattle
Terminal respiratory secretions (or simply terminal secretions),, known colloquially as a death rattle, are sounds often produced by someone who is near death as a result of fluids such as saliva and bronchial secretions accumulating in the throat and upper chest. Those who are dying may lose their ability to swallow and may have increased production of bronchial secretions, resulting in such an accumulation. Usually, two or three days earlier, the symptoms of approaching death can be observed as saliva accumulates in the throat, making it very difficult to take even a spoonful of water. Related symptoms can include shortness of breath and rapid chest movement. While death rattle is a strong indication that someone is near death, it can also be produced by other problems that cause interference with the swallowing reflex, such as brain injuries. It is sometimes misinterpreted as the sound of the person choking to death or gargling. Timing This symptom most commonly appears s ...

Rattle (percussion Instrument)
A rattle is a type of percussion instrument which produces a sound when shaken. Rattles are described in the Hornbostel–Sachs system as ''Shaken Idiophones or Rattles (112.1)''. According to Sachs, Rattles include: * Maracas, widely used in Cha Cha Cha and jazz. ** Chac-chac, as known in Trinidad, Dominica and the French Antilles. * The egg-shaped plastic chicken shake, filled with steel shot and available in varying tones depending on the size and quantity of shot. * Folk instruments especially used in ceremonial dance. * Toy rattles for infants. Though there are many different sorts of rattles, some music scores indicate simply a rattle (or the corresponding terms French ''claquette'', ''hochet''; Ger. ''Rassel'', ''Schnarre''; It. ''nacchere''). Examples * Chankana * Ganzá * Hosho * Maracas * Maracitos * Katsa * Chajchas * Rainstick * Kashaka History In Ancient Egypt, rattles were used during funerary rituals to signify regeneration in the after-l ...
