Lethality

Lethality (also called deadliness or perniciousness) is how capable something is of causing death. Most often it is used when referring to chemical weapons, biological weapons, or their toxic chemical components. The use of this term denotes the ability of these weapons to kill, but also the possibility that they may not kill. Reasons for the lethality of a weapon to be inconsistent, or expressed by percentage, can be as varied as minimized exposure to the weapon, previous exposure to the weapon minimizing susceptibility, degradation of the weapon over time and/or distance, and incorrect deployment of a multi-component weapon.

This term can also refer to the after-effects of weapon use, such as Nuclear Fallout, which has highest lethality nearest the deployment site, and in proportion to the subject's size and nature; e.g. a child or small animal.

Lethality can also refer to the after-effects of a chemical explosion. A lethality curve can be developed for process safety reasons to protect people and equipment. The impact is typically greatest closest to the explosion site and lessens to the outskirts of the impact zone. Pressure, toxicity and location affect the lethality.

Leigh Matthews

Leigh Raymond Matthews AM (born 1 March 1952) is a former Australian rules footballer and coach. He played for Hawthorn in the Victorian Football League (VFL) and coached Collingwood and the Brisbane Lions.

Squat, short legged and barrel-chested, Matthews earned the iconic nickname "Lethal Leigh" due to his physical as well as skilful style of play. He is officially recognised as the "best player of the 20th century", according to the AFL, is a Legend in the AFL Hall of Fame, is on the Hawthorn and AFL Teams of the Centuries and is one of the most successful AFL coaches of all time. In 2008, Matthews was named second, behind Wayne Carey, as part of Mike Sheahan's list of the top 50 players of all time, published in the book 'The Australian Game of Football', which was released by the AFL to celebrate 150 years of Australian rules football. He is now an AFL commentator on television with the Seven Network and on Radio with 3AW Football.

Playing career

Early career

Matthews played his junior football at the Chelsea Football Club, and joined Hawthorn at the age of sixteen, having already played senior suburban football. Part of a footballing family, Matthews' brother Kelvin had played 155 games at Hawthorn and Geelong. Matthews made his senior debut for the Hawks in round 16 of the 1969 against Melbourne, as a forward pocket, crumbing around the feet of Hawthorn’s champion full forward, Peter Hudson. Matthews kicked a goal with his first kick and went on to kick at least one goal in each of his five games that year, winning the club's Best First Year Player award. By mid-way through 1970, Matthews had earned a regular place in the team, as a rover rotating forward, and was immediately impressive, kicking 20 goals from 16 games for the season.

Set (music)

A set (pitch set, pitch-class set, set class, set form, set genus, pitch collection) in music theory, as in mathematics and general parlance, is a collection of objects. In musical contexts the term is traditionally applied most often to collections of pitches or pitch-classes, but theorists have extended its use to other types of musical entities, so that one may speak of sets of durations or timbres, for example.

A set by itself does not necessarily possess any additional structure, such as an ordering. Nevertheless, it is often musically important to consider sets that are equipped with an order relation (called segments); in such contexts, bare sets are often referred to as "unordered", for the sake of emphasis.

Two-element sets are called dyads, three-element sets trichords (occasionally "triads", though this is easily confused with the traditional meaning of the word triad). Sets of higher cardinalities are called tetrachords (or tetrads), pentachords (or pentads), hexachords (or hexads), heptachords (heptads or, sometimes, mixing Latin and Greek roots, "septachords"—e.g.,), octachords (octads), nonachords (nonads), decachords (decads), undecachords, and, finally, the dodecachord.

Set (darts)

A set in darts consists of a sequence of legs (games) played, ending when the count of legs won meets certain criteria. Throwing first is considered an advantage in a leg, so players alternate who throws first in each leg during the set.

Generally, a set will consist of the best of five legs (first player to win three) - although there are some exceptions. The most notable being the Winmau World Masters, where a set is the best of three legs (first to two).

Example

During the final of the 2007 PDC World Darts Championship, Raymond van Barneveld defeated Phil Taylor by seven sets to six in one of the most dramatic darts matches of all-time. The breakdown of how each set went is shown here.

Taylor won the first two sets by three legs to nil, then added the third set before van Barneveld took the next two. The match continued and went to six sets all. Neither player managed to gain a two-leg advantage in the final set "tiebreak" so the deciding leg was played when the score reached 5-5. Before the final leg, the players threw for the bullseye with the nearest given the advantage of throwing first.

Set construction

Set construction is the process by which a construction manager undertakes to build full scale scenery suitable for viewing by camera, as specified by a production designer or art director working in collaboration with the director of a production to create a set for a theatrical, film or television production. The set designer produces a scale model, scale drawings, paint elevations (a scale painting supplied to the scenic painter of each element that requires painting), and research about props, textures, and so on. Scale drawings typically include a groundplan, elevation, and section of the complete set, as well as more detailed drawings of individual scenic elements which, in theatrical productions, may be static, flown, or built onto scenery wagons. Models and paint elevations are frequently hand-produced, though in recent years, many Production Designers and most commercial theatres have begun producing scale drawings with the aid of computer drafting programs such as AutoCAD or Vectorworks.
