Spinner (cell culture)

A Spinner is a type of bioreactor which features an impeller, stirrer or similar device to agitate the contents (usually a mixture of cells, medium and products like proteins that can be harvested). The vessels are usually made out of glass or stainless steel with port holes to accommodate sensors, Medium input or gas flow.

Spinner type vessels are used for mammalian or plant cell culture. They are adequate for cell suspensions and attachment dependent cell types.

Spinnerbait

A Spinnerbait refers to any one of a family of fishing lures that get their name from one or more metal blades shaped so as to spin like a propeller when the lure is in motion, creating varying degrees of flash and vibration that mimics small fish or other prey. The two most popular types of spinnerbaits are the 'in-line spinner' and 'safety pin' spinnerbaits, though others such as the 'tail-spinner' also exist. Spinnerbaits are used principally for catching predatory fish such as perch, pike and bass.

Mode of operation

Spinnerbaits attract predatory fish primarily by activating a special sense organ called the lateral line system through the spinning blade. The Lateral line system enables fish to "touch" and ‘feel’ objects at a distance. Most fish have well-developed sense of touch and can feel the slightest change of water flow around it as a series of vibrations which may warn fish of approaching dangers or indicate the location of prey.

Spinnerbaits can also stimulate other senses of fish to mimic prey by creating flashes in the water (sight) and by creating sound waves in the water (hearing).

Twitch (device)

A twitch is a device that is used to restrain horses for various stressful situations, such as veterinary treatment. Although it may look and sound inhumane, a twitch calms the horse by releasing endorphins as pressure is applied on the twitch, not causing the horse any pain. It is usually made up of a stick-like handle loop of chain or rope on the end, or a metal ring with a rope loop which is wrapped around the upper lip of the horse and tightened. Another design, sometimes called a "humane" twitch, is a plier-like clamp that squeezes the lip with motion akin to that seen in a nutcracker. The aluminium screw twitch is yet another form of twitch.

How the twitch works

The upper lip of the horse is grasped and the loop of chain or rope is placed around it, then the handle of the twitch is twisted until the loop is firmly around the lip. A wooden handled twitch has the disadvantage that it requires a handler and the handle may injure the horse handler if the horse throws its head. Other twitches may be attached to the halter or headcollar. An emergency twitch can be improvised by placing a loop of leather or heavy cord around the nose and tightening it by twisting a stick around and around until it is tightened sufficiently.

Twitch.tv

Twitch.tv is a live streaming video platform owned by Twitch Interactive, a subsidiary of Amazon.com. Introduced in June 2011 as a spin-off of the general-interest streaming platform Justin.tv, the site primarily focuses on video gaming, including playthroughs of video games, broadcasts of esports competitions, and more recently, creative content. Content on the site can either be viewed live, or viewed via Video on demand.

The popularity of Twitch would eclipse that of its general-interest counterpart; in October 2013, the website had 45 million unique viewers, and by February 2014, it was considered the fourth largest source of peak Internet traffic in the United States. At the same time, Justin.tv's parent company was re-branded as Twitch Interactive to represent the shift in focus – Justin.tv was shut down in August 2014. The site has also branched out into music-related streams and content. In 2015, Twitch announced it had more than 1.5 million broadcasters and 100 million visitors per month.

Twitch (EP)

Twitch is an EP, and the first official release, by Australian alternative rock band Jebediah. It was released on 5 August 1996 by record label Murmur.

Background and recording

In January 1996 Jebediah were selected to play the local leg of the Summersault festival, run by promoter Steve Pavlovic, which featured Beastie Boys, Foo Fighters, Sonic Youth, Beck, Pavement and Rancid. In March that year they recorded five songs with Chris Dickie – an English sound engineer who had worked with The Pogues, Morrissey and Depeche Mode before moving to Australia in 1994 – at the Poons Head Studios in Western Australia. These were the first songs that the band had ever recorded.

In April the band signed with Murmur, an imprint of Sony Music Australia, following which they embarked on a number of national tours. The first with label stable-mates Something for Kate (called "Unipalooza") was for six weeks, performing at universities all around Australia. This was followed by supporting Snout and Automatic on their national tour in June. The band also won its first WAMi award for 'Best Stage Presence' that year.
