Drum and bass is a genre of electronic dance music characterised by fast breakbeats with heavy bass and sub-bass lines, samples, and synthesizers. The genre grew out of the UK's rave scene in the 1990s.
A phonograph, in its later forms also called a gramophone or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogue recording and reproduction of sound. The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record". To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones.
The western blot, or western blotting, is a widely used analytical technique in molecular biology and immunogenetics to detect specific proteins in a sample of tissue homogenate or extract. Besides detecting the proteins, this technique is also utilized to visualize, distinguish, and quantify the different proteins in a complicated protein combination.
Scratching, sometimes referred to as scrubbing, is a DJ and turntablist technique of moving a vinyl record back and forth on a turntable to produce percussive or rhythmic sounds. A crossfader on a DJ mixer may be used to fade between two records simultaneously.
In medicine, venipuncture or venepuncture is the process of obtaining intravenous access for the purpose of venous blood sampling or intravenous therapy. In healthcare, this procedure is performed by medical laboratory scientists, medical practitioners, some EMTs, paramedics, phlebotomists, dialysis technicians, and other nursing staff. In veterinary medicine, the procedure is performed by veterinarians and veterinary technicians.
A stylus is a writing utensil or a small tool for some other form of marking or shaping, for example, in pottery. It can also be a computer accessory that is used to assist in navigating or providing more precision when using touchscreens. It usually refers to a narrow elongated staff, similar to a modern ballpoint pen. Many styluses are heavily curved to be held more easily. Another widely used writing tool is the stylus used by blind users in conjunction with the slate for punching out the dots in Braille.
Pathé Records was an international record company and label and producer of phonographs, based in France, and active from the 1890s through the 1930s.
A magnetic cartridge, more commonly called a phonograph cartridge or phono cartridge or (colloquially) a pickup, is an electromechanical transducer that is used to play records on a turntable.
An acetate disc is a type of phonograph record generally used from the 1930s to the late 1950s for recording and broadcast purposes and still in limited use today.
The overwhelming majority of records manufactured have been of certain sizes, playback speeds, and appearance. However, since the commercial adoption of the gramophone record, a wide variety of records have also been produced that do not fall into these categories, and they have served a variety of purposes.
Piracy Funds Terrorism Volume 1, usually referred to simply as Piracy Funds Terrorism, is a mixtape produced by British recording artist M.I.A. and American DJ Diplo featuring vocal tracks intended for M.I.A.'s debut album Arular mashed up with samples of other recordings. The mixtape was produced by the two artists at Diplo's home studio in Philadelphia, Pennsylvania. It was not officially released, but was distributed at M.I.A.'s live shows and via the internet to promote the release of her much-delayed debut album. Despite its unofficial status, the mixtape received general acclaim among critics. Several music publications included the mixtape in their listings of the best albums of 2004.
Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin, hollow needle is inserted into the mass for sampling of cells that, after being stained, are examined under a microscope (biopsy). The sampling and biopsy considered together are called fine-needle aspiration biopsy (FNAB) or fine-needle aspiration cytology (FNAC). Fine-needle aspiration biopsies are very safe minor surgical procedures. Often, a major surgical biopsy can be avoided by performing a needle aspiration biopsy instead, eliminating the need for hospitalization. In 1981, the first fine-needle aspiration biopsy in the United States was done at Maimonides Medical Center. Today, this procedure is widely used in the diagnosis of cancer and inflammatory conditions. Fine needle aspiration is generally considered a safe procedure. Complications are infrequent.
Surface metrology is the measurement of small-scale features on surfaces, and is a branch of metrology. Surface primary form, surface fractality, and surface finish are the parameters most commonly associated with the field. It is important to many disciplines and is mostly known for the machining of precision parts and assemblies which contain mating surfaces or which must operate with high internal pressures.
Final Scratch is a DJ tool created by the Dutch company N2IT with input from Richie Hawtin and John Acquaviva that allows manipulation and playback of digital audio sources using traditional vinyl and turntables. It seeks to cross the divide between the versatility of digital audio and the tactile control of vinyl turntablism.
The detection of genetically modified organisms in food or feed is possible by biochemical means. It can either be qualitative, showing which genetically modified organism (GMO) is present, or quantitative, measuring in which amount a certain GMO is present. Being able to detect a GMO is an important part of GMO labeling, as without detection methods the traceability of GMOs would rely solely on documentation.
The slate and stylus are tools used by blind people to write text that they can read without assistance. Invented by Charles Barbier as the tool for writing letters that could be read by touch, the slate and stylus allow for a quick, easy, convenient and constant method of making embossed printing for Braille character encoding. Prior methods of making raised printing for the blind required a movable type printing press.
In the production of phonograph records – discs that were commonly made of shellac, and later, vinyl – sound was recorded directly onto a master disc at the recording studio. From about 1950 on it became usual to have the performance first recorded on audio tape, which could then be processed and/or edited, and then dubbed on to the master disc.
Ronald K. Keys Jr. aka DJ Swamp is an American hip hop DJ, turntablist, producer and vocalist. He was born in Cleveland, Ohio, United States. He currently resides in Los Angeles, United States. In 1996, he won the title of US DMC Champion, his first year entering the tournament. Swamp toured with Beck for four years and later broke away into a solo career with his release "Never is Now" in 2001. Alternative Press gave "Never is Now" an 8/10 rating.
A breast biopsy is usually done after a suspicious lesion is discovered on either mammography or ultrasound to get tissue for pathological diagnosis. Several methods for a breast biopsy now exist. The most appropriate method of biopsy for a patient depends upon a variety of factors, including the size, location, appearance and characteristics of the abnormality. The different types of breast biopsies include fine-needle aspiration (FNA), vacuum-assisted biopsy, core needle biopsy, and surgical excision biopsy. Breast biopsies can be done utilizing ultrasound, MRI or a stereotactic biopsy imaging guidance. Vacuum assisted biopsies are typically done using stereotactic techniques when the suspicious lesion can only be seen on mammography. On average, 5–10 biopsies of a suspicious breast lesion will lead to the diagnosis of one case of breast cancer. Needle biopsies have largely replaced open surgical biopsies in the initial assessment of imaging as well as palpable abnormalities in the breast.
UK garage, abbreviated as UKG, is a genre of electronic dance music which originated in England in the early to mid-1990s. The genre was most clearly inspired by garage house, but also incorporates elements from dance-pop, R&B, and jungle. It is defined by percussive, shuffled rhythms with syncopated hi-hats, cymbals, and snares, and may include either 4/4 house kick patterns or more irregular "2-step" rhythms. Garage tracks also commonly feature 'chopped up' and time-stretched or pitch-shifted vocal samples complementing the underlying rhythmic structure at a tempo usually around 130 BPM.
