Group may refer to:
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.
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.
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%".
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.
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.
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.
Düsseldorf is a 1996 album by the German band La! Neu?, recorded in the year following the band's formation in summer 1995. The album features several members of the Düsseldorf band Kreidler, and was recorded primarily in the city after which it is named. It was released during a period of intense musical activity for Klaus Dinger, who had just signed to the Japanese record label Captain Trip Records, which he used to market two previously unreleased Neu! albums. It is La! Neu?'s debut album, although of the musicians featured on it only Dinger and Victoria "Wicki" Wehrmeister would form a consistent part of the future La! Neu?
In late 1994 Dinger was contacted by a group of young Düsseldorf musicians who had recently formed Kreidler and released their debut album "Riva". Dinger jammed with the band twice in his Düsseldorf studios and was pleased with the result (although these sessions were not recorded). In 1995 he travelled to Berlin to sit-in on sessions for Kreidler's second album "Weekend", and quickly identified keyboardist Andreas Reihse as a future collaborator.
