Shot grouping

In shooting, a shot grouping, or simply grouping, is the placement of multiple shots on a target, the shots taken in one shooting session. The closeness of the grouping, the nearness of all the shots to each other, is a measure of the accuracy of a weapon, and a measure of the shooter's consistency and skill.

Uses of the term

For firearms that shoot one round at a time, a shot grouping can be used to measure the accuracy of the system comprised out of weapon as well as the precision and uniformity of the ammunition by fixing the weapon into position on a test mount, and aiming it at a target. Multiple shots using rounds from same type and batch are fired to observe how the weapon groups the shots. If a person holds the weapon and shoots it, the grouping measures the combination of the person's skill and the weapon's accuracy.

In shotgun shooting, the grouping is also called the pattern. The pattern is the spread of shot from a single shotgun shell, measured as the smallest circle containing all the shots on the target. The barrel of a shotgun is designed to deliver a wide or narrow grouping, depending on the expected use. Shooting at close range indicates a cylinder bore barrel to deliver a wide grouping, while for hunting at longer distances such as 50 yards or meters, a choke is recommended for a tighter grouping.

Stratigraphic unit

A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.

Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%".

Lithostratigraphic units

Sequences of sedimentary and volcanic rocks are subdivided on the basis of their lithology. Going from smaller to larger in scale, the main units recognised are Bed, Member, Formation, Group and Supergroup.

Bed

A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in the case of a marker horizon.

Member

A member is a named lithologically distinct part of a formation. Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation.

Private (web series)

Private is an American Web series produced by Alloy Entertainment based on the novels of the same name by Kate Brian.

The series was announced in May 2009, beginning with a contest allowing female readers the chance to audition for the role of Kiran Hayes. It was also announced that the series would adapt the first four books via 20 episodes, each with a standard length of four to six minutes.

A DVD with episodes of the series was released by Newvideo.

Contest

Private (film)

Private is a 2004 film directed by Saverio Costanzo. A debut film by the director, the film is a minimalist psychological drama about a Palestinian family of seven suddenly confronted with a volatile situation in their home that in many ways reflects the larger ongoing conflict between Palestinians and Israel.

Initially selected as the official entry from Italy for the foreign language film category at the 78th Academy Awards, Private was disqualified as its main spoken language is not in Italian (a rule that was changed, effective with the next year's Oscars, partly due to this film). The film has received the Golden Leopard (best film) award at the 57th Locarno International Film Festival.

Plot

Mohammad, his wife and their five children live in a large, isolated house located halfway between a Palestinian village and an Israeli settlement. The house, in the crossfire of the two sides, is a strategic lookout point that the Israeli army decides to seize, confining the family to a few downstairs rooms in daytime and a single room at night. Mohammad refuses to leave this home and, reinforced by his principles against violence, decides to find a way to keep his family together in the house until the Israeli soldiers move on.
