Datasets are tables consisting of molecular, morphological, ethological and / or other characters and a list of operational taxonomic units ( OTUs ) which may be genes, individuals, populations, species, or larger taxa that are presumed to be monophyletic and that are presumed to form, all together, one large clade ; phylogenetic analysis reconstructs the branching pattern within that clade.

Furthermore, within CGS, there are several plausible choices of electromagnetic units, leading to different unit " sub-systems ", including Gaussian, " ESU ", " EMU ", and Heaviside – Lorentz.

The units gram and centimetre remain useful as prefixed units within the SI system, especially for instructional physics and chemistry experiments, where they match the small scale of table-top setups.

The contemporary Ecuadorian Army has a large component of jungle and special forces infantry units implemented within its structure.

Languages that are official within regions, provinces or federal units within a State ( for example Catalan in Spain ) are not classified as official languages of the State and may therefore benefit from the Charter.

Kekulé's idea of assigning certain atoms to certain positions within the molecule, and schematically connecting them using what he called their " Verwandtschaftseinheiten " (" affinity units ", now called " valences " or " bonds "), was based largely on evidence from chemical reactions, rather than on instrumental methods that could peer directly into the molecule, such as X-ray crystallography.

The result was poor coordination between the two forward Corps and units within them.

If the tops of the rock units within the folds remain pointing upwards, they are called anticlines and synclines, respectively.

Stretching of units can result in their thinning ; in fact, there is a location within the Maria Fold and Thrust Belt in which the entire sedimentary sequence of the Grand Canyon can be seen over a length of less than a meter.

Magnetic stratigraphers look for signs of magnetic reversals in igneous rock units within the drill cores.

In his book " Easy the Hard Way ", Joe Pasternak, head of one of the other musical units within MGM, singled out Kelly for his patience and willingness to spend as much time as necessary to enable the ailing Garland to complete her part.

* Gene therapy is a crucial plot element in the video game Metal Gear Solid, where it has been used to illegally enhance the battle capabilities of soldiers within the US military, and their Next Generation Special Forces units.

Indeed in 1939, laws were passed that allowed Muslims to be permitted to join the National Fascist Party and in particular the Muslim Association of the Lictor ( Associazione Musulmana del Littorio ), and the 1939 reforms allowed the creation of Libyan military units within the Italian army.

The outside surface of the solid units shall be of an exterior grade of panel board such as plywood, plastic coated panel board, high density particle board, asbestos-cement board, or any other product locally obtainable upon recommendation of your building supply dealer.

For specialized types of displays, such as large three-dimensional units reproducing a product, package, human or animal figures, etc., reinforced plastics and rotationally molded vinyl plastisols are other materials frequently used.

Neither G nor M < sub >☉</ sub > can be measured to high accuracy in SI units, but the value of their product is known very precisely from observing the relative positions of planets ( Kepler's Third Law expressed in terms of Newtonian gravitation ).

Only the product is required to calculate planetary positions for an ephemeris, which explains why ephemerides are calculated in astronomical units and not in SI units.

The product of f ′( g ( 10 )) and g ′( 10 ) therefore has the correct units of Pascals per second.

It is now denoted by He showed that this ring has the four units ± 1 and ± i, that the non-zero, non-unit numbers fall into two classes, primes and composites, and that ( except for order ), the composites have unique factorization as a product of primes.

The units of momentum are the product of the units of mass and velocity.

While Nintendo's Research & Development 3 division ( R & D3 ) was focused on developing the Nintendo 64, the other two engineering units were free to experiment with new product ideas.

The basic reason is that no productive factor with a non-zero marginal product is left unutilized, and the units of each factor are so allocated as to yield the same indirect marginal utility in all uses, a basic efficiency condition ( if this indirect marginal utility were higher in one use than in other ones, a Pareto improvement could be achieved by transferring a small amount of the factor to the use where it yields a higher marginal utility ).

An element is irreducible if it cannot be written as a product of two ring elements that are not units.

The group of units of R is the product of the groups of units of R < sub > i </ sub >.

The effort expended in separating a mass F of feed of assay xf into a mass P of product assay xp and waste of mass W and assay xw is expressed in terms of the number of separative work units needed, given by the expression SWU

However, these dimensions have fundamental significance in terms of Planck units ; when expressed in SI units, the gravitational constant is dimensionally and numerically equal to the cube of the Planck length divided by the product of the Planck mass and the square of Planck time.

In facsimile systems, the cooperation factor is the product of the total image scanning length and the scanning density, given by CF = L σ, where L is the scanning line length and σ is the scanning line density, both in compatible units.

Production in the 16-year " CBS period " reached as high as 50 units per day around 1978-79, but sales declined as 1980 approached, and the Mark II Stage Piano was introduced in an attempt to revitalize the product.
