Crunch may refer to:
The crunch is one of the most common abdominal exercises. It primarily works the rectus abdominis muscle and also works the obliques.
A crunch begins with lying face up on the floor with knees bent. The movement begins by curling the shoulders towards the pelvis. The hands can be behind or beside the neck or crossed over the chest. Injury can be caused by pushing against the head or neck with hands.
The difficulty of the crunch can be increased by lying on a declined bench or holding a weight under the chin, on the chest or behind the head. Crunch exercises may be performed on exercise balls. Increasing the distance will also increase the load on the abdominals due to leverage.
The curl-up is taught by spine biomechanics professor Dr. Stuart McGill, and he considers it to be a safer alternative to the crunch, which differs from the sit-up. McGill has done extensive research on the effects of crunch exercises on the back, which can be especially harmful for those rehabilitating their backs from an injury.
Crunch is an annual Art and Music festival that takes place in November in Hay-on-Wye, Wales. It is held by the Institute of Art and Ideas, a non-profit organization which hosts a number of cultural events throughout the year. Crunch brings together the world’s leading artists, curators and critics to debate the questions that lie at the core of contemporary art. The 3-day festival features talk sessions and debates, live music, performance acts, creative workshops, art exhibitions and late night parties.
The festival has doubled in size and features controversial art historian Julian Stallabrass, artist Susan Hiller and postmodern painter and psychoanalyst Bracha Ettinger debating how art and creativity make us alive; Serpentine Director Hans Ulrich-Obrist on the rise of the curators and outspoken artist Jake Chapman in conversation with Paradise Row founder Nick Hackworth.
With exhibitions from galleries such as The View, the UK's contemporary art scene combines with a debate series featuring significant cultural figures such as former Director of the Royal Shakespeare Company Adrian Noble, novelist Mark Haddon and art historian Griselda Pollock.
This is a list of Goa'uld technologies in the Stargate franchise. The Goa'uld are the main adversaries for most of the run of Stargate SG-1. They scavenged or conquered most of their advanced technologies from other races. However, there are innovators amongst the Goa'uld; Anubis and Ba'al in particular have been depicted with a great deal of technological ingenuity. Rather than being designed as practical, many Goa'uld devices, such as the staff weapon, are designed to have higher visual impact, meant to intimidate and reinforce their position as gods to their followers. Some pieces of Goa'uld technology, such as the hand device and the healing device, respond only to mental commands and require naqahdah in the bloodstream of the user to operate.
The GNU Core Utilities or coreutils is a package of GNU software containing reimplementations for many of the basic tools, such as cat, ls, and rm, used on Unix-like operating systems. It is a combination of a number of earlier packages, including textutils, shellutils, and fileutils, along with some other miscellaneous utilities.
The GNU core utilities support long options as parameters to the commands, as well as (unless the POSIXLY_CORRECT environment variable is set) the relaxed convention allowing options even after the regular arguments. Note that this environment variable enables a different functionality in BSD.
TAC is a Swedish-based building automation company in the fields of both energy solutions and security. It also operates in other countries including the United Kingdom and the USA and was originally established as Tour Agenturer in 1925 in Stockholm. TAC has announced a name change to Schneider Electric, its parent company, to take place in October 2009.
Founded as Tour Agenturer in Stockholm in 1925, the company produced a product range focusing particularly on draught regulators and radiator valves. It continued to develop its product range introducing the first transistorized heating regulator in 1962 and . a computer-based system for climate control in 1974. Tour Agenturer became Tour & Andersson in 1977 following a merger with AH Andersson.
Over the following years, Tour & Andersson extend its product range to include an integrated access control system and hotel management and signal system in 1980 and 1981 respectively. In 1987 it released Micro 7, an IBM PC-based control system with an easier user interface than previously available and operated with a mouse in a similar fashion to modern day computers.
A tic is a sudden, repetitive, nonrhythmic motor movement or vocalization involving discrete muscle groups. Tics can be invisible to the observer, such as abdominal tensing or toe crunching. Common motor and phonic tics are, respectively, eye blinking and throat clearing.
Tics must be distinguished from movements of other movement disorders such as chorea, dystonia, myoclonus; movements exhibited in stereotypic movement disorder or some autistic people, and the compulsions of obsessive-compulsive disorder (OCD) and seizure activity.
Tics are classified as either motor or phonic, and simple or complex.
Motor tics are movement-based tics affecting discrete muscle groups.
Phonic tics are involuntary sounds produced by moving air through the nose, mouth, or throat. They may be alternately referred to as verbal tics or vocal tics, but most diagnosticians prefer the term phonic tics to reflect the notion that the vocal cords are not involved in all tics that produce sound.
