Beatmatching or pitch cue is a disc jockey technique of pitch shifting or timestretching an upcoming track to match its tempo to that of the playing track, to adjust them such that the beats are synchronised — e.g. the kicks and snares in two house records hit at the same time when both records are played simultaneously. Beatmatching is a component of beatmixing which employs beatmatching combined with equalization, attention to phrasing and track selection in an attempt to make a single mix that flows together and has a good structure; the technique was developed to keep the people from leaving the dancefloor at the end of the song. These days it is considered basic among disc jockeys in electronic dance music genres, it is standard practice in clubs to keep the constant beat through the night if DJs change in the middle. Beatmatching is no longer considered a novelty, new digital software has made the technique much easier to master; the beatmatching technique consists of the following steps: While a record is playing, start a second record playing, but only monitored through headphones, not being fed to the main PA system.

Use gain control on the mixer to match the levels of the two records. Restart and slip-cue the new record at the right time, on beat with the record playing. If the beat on the new record hits before the beat on the current record the new record is too fast. If the beat on the new record hits after the beat on the current record the new record is too slow. Continue this process until the two records are in sync with each other, it can be difficult to sync the two records so manual adjustment of the records is necessary to maintain the beat synchronization. Fade in parts of the new track while fading out the old track. While in the mix, ensure that the tracks are still synchronized, adjusting the records if needed; the fade can be repeated several times, for example, from the first track, fade to the second track back to first to second again. One of the key things to consider when beatmatching is the tempo of both songs, the musical theory behind the songs. Attempting to beatmatch songs with different beats per minute will result in one of the songs sounding too fast or too slow.

When beatmatching, a popular technique is to vary the equalization of both tracks. For example, when the kicks are occurring on the same beat, a more seamless transition can occur if the lower frequencies are taken out of one of the songs, the lower frequencies of the other song is boosted. Doing so creates a smoother transition; the pitch and tempo of a track are linked together: spin a disc 5% faster and both pitch and tempo will be 5% higher. However, some modern DJ software can change pitch and tempo independently using time-stretching and pitch-shifting, allowing harmonic mixing. There is a feature in modern DJ software which may be called "master tempo" or "key adjust" which changes the tempo while keeping the original pitch. Beatmatching was invented by Francis Grasso in early 1970s, he was counting the tempo with a metronome and looking for records with the same tempo. A mixer was built for him by Alex Rosner which let him listen to any channel in the headphones independently of what was playing on the speakers.

That and turntables with pitch control enabled him to mix tracks with different tempo by changing the pitch of the cued track to match its tempo with the track being played by ear. The technique he originated hasn't changed since; these days beat-matching is considered central to DJing, features making it possible are a requirement for DJ-oriented players. In 1978, the Technics SL-1200MK2 turntable was released, whose comfortable and precise sliding pitch control and high torque direct drive motor made beat-matching easier and it became the standard among DJs. With the advent of the compact disc, DJ-oriented Compact Disc players with pitch control and other features enabling beat-matching, dubbed CDJs, were introduced by various companies. More software with similar capabilities has been developed to allow manipulation of digital audio files stored on computers using turntables with special vinyl records or computer interface. Other software including algorithmic beat-matching is Ableton Live, which allows for realtime music manipulation and deconstruction, or Mixmeister, a DJ Mixset creation tool.

Freeware software such as Rapid Evolution can detect the beats per minute and determine the percent BPM difference between songs. The change from pure hardware to software is on the rise, big DJs are introducing new equipment to their kits such as the laptop, dropping the difficulty of carrying hundreds of CDs with them; the creation of the mp3-player allowed DJs to have an alternative tool for DJIng. Limitations with mp3-player DJing equipment has meant that only second generation equipment such as the IDJ2 or the Cortex Dmix-300 have the pitch control that alters tempo and allows for beat-matching on a digital music player. However, recent additions to the Pioneer CDJ family, such as the CDJ-2000, allow mp3-player and other digital storage devices to be connected to the CDJ device via USB; this allows the DJ to make use of the beat-matching capabilities of the CDJ unit whilst playing dig

Communist Workers Union of Germany

Communist Workers Union of Germany was a council communist organization in Germany. KAUD was founded in December 1931 by the'Frankfurt-Breslauer Tendency' of the Allgemeine Arbeiter-Union – Einheitsorganisation and sections of KAPD and AAUD. KAUD appealed to workers to form autonomous workers councils. One of their first publications was a document drafted by Jan Appel and developed by the Group of International Communists of Holland, Foundations of Communist Production and Distribution by the Kommunistische Arbeiter-Union Deutschlands in 1930. An English translation by Mike Baker was published in 1990. KAUD published a periodical: Der Kampfruf. Shortly after the 1933 National Socialist takeover, the KAUD disappeared. During the spring of 1933, the group published magazines with different names. In December 1933, the organization was ripped apart by internal strife. By 1934, some KAUD cadres had regrouped as Revolutionäre Obleute

HD 2454

HD 2454 is a probable binary star system in the zodiac constellation of Pisces. With an apparent visual magnitude of 6.04, it is near the lower limit of visibility to the naked eye under good seeing conditions. An annual parallax shift of 27.36 mas as measured from Earth's orbit provides a distance estimate of 199 light years. It has a high proper motion, traversing the celestial sphere at a rate of 0.208 arcseconds per year, is moving closer to the Sun with a heliocentric radial velocity of −10 km/s. The visible component of this system is an F-type main-sequence star with a stellar classification of F5 V Sr, showing an abnormally strong line of singly-ionized strontium at a wavelength of 4077 Å, it has an estimated 1.23 times the mass of 1.6 times the Sun's radius. The star is about 1.9 billion years old with a rotation period of around three days. It is radiating 4.6 times the Sun's luminosity from its photosphere at an effective temperature of around 6,508 K. HD 2454 was the first star to be identified as a Barium dwarf, by Tomkin et al. and is the brightest such object.

It displays a mild overabundance of the element barium, hypothesized to have been accreted when an unresolved white dwarf companion was passing through the asymptotic giant branch stage. The visible component displays significant overabundances of three s-process peak elements that are generated during the RGB phase, as well as a mild overabundance of carbon. In contrast, it shows severe depletion of lithium and beryllium, as well as a notable underabundance of boron; the surface abundances of these lighter elements may have been altered during the mass transfer process, having been consumed in the core region of the companion

Chromidotilapia guntheri

Chromidotilapia guntheri, Günther's mouthbrooder, is a cichlid from Africa. It was considered to consist of two subspecies, the common C. g. guntheri ranges from Liberia to Equatorial Guinea and Niger, the critically endangered C. g. loennbergi, thought to be restricted to Lake Barombi-ba-Kotto, a small crater lake in Cameroon but these subspecies are not supported by subsequent authorities. The species is noted for being a biparental mouthbrooder. Eggs are taken in the parents' mouth. Unlike many mouthbrooding cichlid species, both parents participate in the mouthbrooding. Günther's mouthbrooder is restricted to lowland environments where it can be found in waters in coastal floodplains and forests, showing a preference for slow or still waters with submerged tree roots and fallen branches to provide cover; the species in the genus Chromidotilapia are bottom feeding omnivores and they feed on small invertebrates, organic detritus, other small food items. Their feeding behaviour is similar to that of some Neotropical cichlid genera such as Geophagus and Satanoperca in that they take up mouthfuls of the substrate which they sift for edible items before expelling the waste through their gills and the mouth.

Chromidotilapia guntheri are sexually dimorphic and the males and females differ in size with the males being larger than the females, males growing to 20 centimetres and females to 13 centimetres. Other sexual differences are that first ray in the pectoral fin in males is more extended when compared to those of females; the female is more colorful than the male. Both sexes are a tan color, but the female has a pink belly and a metallic white stripe on the dorsal fin; the common name and the specific name both honour the German-born British zoologist and herpetologist Albert Günther of the British Museum

Pringle Falls

Pringle Falls is a series of rapids or drops on the upper Deschutes River in the U. S. state of Oregon. From just downstream of Wyeth Campground, the rapids begin with about 600 feet of whitewater rated class II on the International Scale of River Difficulty; the next 300 feet is class III (intermediate] ending in a class IV drop. Soggy Sneakers: A Paddler's Guide to Oregon's Rivers says, "Only expert kayakers should consider this drop, only after scouting, it is not a rapids for open canoes."The Northwest Waterfall Survey describes the rapids as "the first major waterfall along the Deschutes River" but qualifies this by adding that the waterfall has been reported to be a cascade series with a total vertical drop of 25 feet spread over a horizontal distance of 850 feet. The survey notes that the falls can not be seen from nearby other public property. Most boaters portage 1.5 miles around the falls, taking out of the river at Wyeth Campground and putting back in below the falls at Pringle Falls Campground.

Shorter portages are not feasible. The two campgrounds, one upstream and one downstream of the private land, are within the Deschutes National Forest; the falls were named for O. M. Pringle, who bought 160 acres of government land here in 1902 under provisions of the Timber and Stone Act; the falls were known as the Fish Trap, a reference to its use by Native Americans, who caught fish by the gills as they swam upriver through shallow channels. A post office named Pringlefalls operated from 1916 to 1918
