702 (group)

702 (pronounced "Seven-Oh-Two"), named after the area code of their hometown of Las Vegas, Nevada, was an American platinum-selling trio. Originally a quartet, the group became a trio, which includes sisters Irish (born June 2, 1980), and LeMisha 'Misha' (born June 10, 1978) Grinstead, and lead singer Kameelah Williams. Irish's twin sister Orish Grinstead (June 2, 1980 – April 20, 2008) was a founding member and later a substitute vocalist.

History

In Las Vegas, sisters LeMisha and Irish Grinstead, and their friend Kameelah Williams, were students at Cheyenne High School. Irish, her twin sister Orish, and LeMisha occasionally sang in the lobby of Caesars Palace where they were discovered by actor/comedian Sinbad. He visited their home in order to convince their parents to send the trio to Atlanta for a convention and music competition. Though the girls missed the deadline for entry, Sinbad used his name to get them in. "Sweeta than Suga," as they were then called (Sinbad suggested the name), came in second in the competition. As the convention was nearing a close, they met Michael Bivins (of New Edition and Bell Biv DeVoe) who agreed to work with the sisters. They were briefly joined by their cousin Amelia Childs. After they made their recorded debut on Subway's hit single "This Lil' Game We Play", Amelia dropped out of the group and was replaced by Kameelah Williams. After recording a few demos as a quartet including "Steelo", and "Get It Together", Orish decided to leave the group (even though her vocals appear on the first album). Bivins continued to work with different producers and songwriters to get the right feel for their first album. The reconfigured group was christened "702," which is Las Vegas' area code, a name which Bivens suggested.

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.
