Political hip hopPolitical hip hop is a subgenre of hip hop music that was developed in the 1980s as a way of turning hip hop into a form of political activism. Political hip-hop generally uses the medium of hip hop music to comment on sociopolitical issues and send political messages to inspire action, create social change, or to convince the listener of a particular worldview. It was inspired partially by politically-focused 1970s artists such as The Last Poets and Gil Scott-Heron, as well as the Black Power movement and revolutionary politics of the 1960s and 1970s.
Human musculoskeletal systemThe human musculoskeletal system (also known as the human locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton, muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together.
OsteotomyAn osteotomy is a surgical operation whereby a bone is cut to shorten or lengthen it or to change its alignment. It is sometimes performed to correct a hallux valgus, or to straighten a bone that has healed crookedly following a fracture. It is also used to correct a coxa vara, genu valgum, and genu varum. The operation is done under a general anaesthetic. Osteotomy is one method to relieve pain of arthritis, especially of the hip and knee. It is being replaced by joint replacement in the older patient.
Electro-mechanical gameElectro-mechanical games (EM games) are types of arcade games that operate on a combination of some electronic circuitry and mechanical actions from the player to move items contained within the game's cabinet. Some of these were early light gun games using light-sensitive sensors on targets to register hits, while others were simulation games such as driving games, combat flight simulators and sports games. EM games were popular in amusement arcades from the late 1940s up until the 1970s, serving as alternatives to pinball machines, which had been stigmatized as games of chance during that period.
Iliotibial band syndromeIliotibial band syndrome (ITBS) is the second most common knee injury, and is caused by inflammation located on the lateral aspect of the knee due to friction between the iliotibial band and the lateral epicondyle of the femur. Pain is felt most commonly on the lateral aspect of the knee and is most intensive at 30 degrees of knee flexion. Risk factors in women include increased hip adduction and knee internal rotation. Risk factors seen in men are increased hip internal rotation and knee adduction.
Hip hop productionHip hop production is the creation of hip hop music in a recording studio. While the term encompasses all aspects of hip hop music creation, including recording the rapping of an MC, a turntablist or DJ providing a beat, playing samples and "scratching" using record players and the creation of a rhythmic backing track, using a drum machine or sequencer, it is most commonly used to refer to recording the instrumental, non-lyrical and non-vocal aspects of hip hop.
Avascular necrosisAvascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. Early on, there may be no symptoms. Gradually joint pain may develop which may limit the ability to move. Complications may include collapse of the bone or nearby joint surface. Risk factors include bone fractures, joint dislocations, alcoholism, and the use of high-dose steroids. The condition may also occur without any clear reason. The most commonly affected bone is the femur.
Alternative hip hopAlternative hip hop (also known as alternative rap and experimental hip hop) is a subgenre of hip hop music that encompasses a wide range of styles that are not typically identified as mainstream. AllMusic defines it as comprising "hip hop groups that refuse to conform to any of the traditional stereotypes of rap, such as gangsta, bass, hardcore, and party rap. Instead, they blur genres drawing equally from funk and pop/rock, as well as jazz, soul, reggae, and even folk.
Old-school hip hopOld-school hip hop (also spelled old skool) is the earliest commercially recorded hip hop music and original style of the genre. It typically refers to the music created around 1979 to 1983, as well as any hip hop that does not adhere to contemporary styles. The image, styles and sounds of old-school hip hop were exemplified by figures like Grandmaster Flowers, Grand Wizzard Theodore, Grandmaster Flash, Afrika Bambaataa, DJ Kool Herc, Treacherous Three, Funky Four Plus One, Kurtis Blow, The Sugarhill Gang, Melle Mel, Super-Wolf, West Street Mob, Spoonie Gee, Kool Moe Dee, Busy Bee Starski, Lovebug Starski, DJ Hollywood, The Cold Crush Brothers, Warp 9, T-Ski Valley, Grandmaster Caz, Doug E.
RollingRolling is a type of motion that combines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding. Rolling where there is no sliding is referred to as pure rolling.
