The maritime fleet of the Islamic Republic of Iran Shipping Lines (IRISL Group) comprises 115 ocean-going vessels, with the total capacity of 3.3 million tons deadweight (DWT). The ownership structure of the fleet comprises 87 ocean-going vessels in IRISL and 28 different types of ships under the flag of subsidiaries, including Khazar Shipping, Valfajr as well as Iran-India Shipping Companies. They are manned by 6,000 Iranian personnel including shore staff, masters, deck and engine officers as well as ratings, who work under the flag of the Islamic Republic of Iran in the Caspian Sea, Persian Gulf, international waters and various ports of the world.
IRISL has been sanctioned by the U.S., UN, EU and other parties for its role in advancing Iran's nuclear and ballistic missile programs. However, the return of the line to the market is expected by early Winter 2016, as a result of JCPOA agreement between Iran and EU3+3 in August2015. IRISL has also announced its plans to upgrade to the world's tenth shipping lines by 2020.
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.
