Traditionally, less use has been made of extension in church organs and those designed for classical music, with authorities tending to regard borrowing in general and extension in particular as things to be avoided if possible, except in a few cases where space for pipes is limited, making extension and / or unification necessary.

Kaluza's approach to unification was to embed space-time into a five-dimensional cylindrical world ; one of four space dimensions and one of time.

The rapid expansion of space meant that elementary particles remaining from the grand unification epoch were now distributed very thinly across the universe.

In the same vein, some amount of unification was utilized in some church organs, and even today many church pipe organs utilize some degree of unification in areas where it is not critical to the " classical " sound sought in such instruments, or in instruments where space for pipes is limited.

At the time of unification the bulk of cargo destined for the Witwatersrand area entered through Lourenço Marques ( now Maputo in Mozambique ) owing largely to the relative distance and the ZARs policy of reducing its dependence on the British Empire.

** Real analysis on time scales – a unification of real analysis with calculus of finite differences

Horus may be shown as a falcon on the Narmer Palette dating from the time of unification of Upper and Lower Egypt.

At the time, the struggle for Italian unification was perceived to be waged primarily against the Austrian Empire and the Habsburgs, since they directly controlled the predominantly Italian-speaking northeastern part of present-day Italy and were, together, the most powerful force against unification.

Many leaders of the unification movement were at one time members of this organization.

Anachronism here served to increase legitimacy for the unification of Moldavia and Wallachia into the Kingdom of Romania, at the time the painting was made.

When referring to the events surrounding unification, however, it carries the cultural connotation of the time and the events in the GDR that brought about this " turnaround " in German history.

As Emperor, Napoleon dreamed of doing this, and thus satisfying his own inclinations and winning over liberal and left-wing opinion in France ( which was passionately in favour of Italian unification ) while at the same time supporting the Pope in Rome and thus maintaining conservative and Catholic support in France.

At the time, Victor Emanuel had become a universal symbol of the Italian Risorgimento, the movement pushing towards the unification of Italy.

About this time he developed an interest in the Communist party and in the unification of Vietnam.

Following his fight with Vargas, Trinidad moved up in weight – this time to participate in Don King's middleweight unification tournament featuring IBF champion Bernard Hopkins, WBA champion William Joppy, and WBC champion Keith Holmes.

Although rivals, the WBC's relationship with other sanctioning bodies has improved over time and there have even been talks of unification with the WBA.

It came at an opportune time for rebuilding, since a movement for architectural reform and unification around a Spanish Colonial style was already underway.

Inadvertently, these reforms sparked the unification movement and augmented a middle class demanding further political rights, but at the time backwardness and Prussia's fears of its stronger neighbors were greater concerns.

See time scale calculus for a unification of the theory of difference equations with that of differential equations.

Some of the controversy stems from the fact that the very decision of performing Han unification was made by the initial Unicode Consortium, which at the time was a consortium of North American companies and organizations ( most of them in California ), but included no East Asia government representatives.

Albert is therefore often seen as the father of the Prussian nation, and even as indirectly responsible for the unification of Germany.

In 1908 ( the affair is known under the name Bombaška afera ) the Serbian nationalists tried to kill the king of Montenegro, because they considered him as an obstacle to the unification of all the Serbs in one state.

A position known as " foundherentism ", advanced by Susan Haack, is meant to be a unification of foundationalism and coherentism.

This unification, which was observed by Michael Faraday, extended by James Clerk Maxwell, and partially reformulated by Oliver Heaviside and Heinrich Hertz, is one of the key accomplishments of 19th century mathematical physics.

Mathematically, the unification is accomplished under an SU ( 2 ) × U ( 1 ) gauge group.

Econometrics is the unification of economics, mathematics, and statistics.

Ba ' athism is a revolutionary Arab nationalist ideology that seeks the unification of all claimed Arab lands into a single Arab state.

The unification of two argument graphs is defined as the most general graph ( or the computation thereof ) that is consistent with ( i. e. contains all of the information in ) the inputs, if such a graph exists ; efficient unification algorithms are known.

For contraint frameworks which are strictly compositional, graph unification is the sufficient satisfiability and combination function.

The new particles predicted by models of grand unification cannot be observed directly at particle colliders because their masses are expected to be of the order of the so-called GUT scale, which is predicted to be just a few orders of magnitude below the Planck scale and thus far beyond the reach of currently foreseen collision experiments.

Due to this difficulty, and due to the lack of any observed effect of grand unification so far, there is no generally accepted GUT model.

Grand Unification is reminiscent of the unification of electric and magnetic forces by Maxwell's theory of electromagnetism in the 19th century, but its physical implications and mathematical structure are qualitatively different.

Here, the unification of matter is even more complete, since the irreducible spinor representation 16 contains both the and 10 of SU ( 5 ) and a right-handed neutrino, and thus the complete particle content of one generation of the extended standard model with neutrino masses.

This is already the largest simple group which achieves the unification of matter in a scheme involving only the already known matter particles ( apart from the Higgs sector ).

The unification of forces is possible due to the energy scale dependence of parameters in quantum field theory called renormalization group running, which allows parameters with vastly different values at collider energies to converge at much higher energy scales.

The renormalization group running of the three gauge couplings in the Standard Model has been found to nearly, but not quite, meet at the same point if the hypercharge is normalized so that it is consistent with SU ( 5 ) or SO ( 10 ) GUTs, which are precisely the GUT groups which lead to a simple fermion unification.

Moreover, since we have no idea which Higgs particle has been observed, the smaller electroweak unification is still pending.

This interesting numerical observation is called the gauge coupling unification, and it works particularly well if one assumes the existence of superpartners of the Standard Model particles.

The German Empire () is the common name given to the state officially named the ( literally: " German Realm "), designating Germany from the unification of Germany and proclamation of Wilhelm I as German Emperor on 18 January 1871, to 1918, when it became a federal republic after defeat in World War I and the abdication of the Emperor, Wilhelm II.

The dynastic union of the crowns of the Kingdom of Castile and the Kingdom of Aragon in 1492 is seen frequently as the starting pont of the unification of the modern kingdom of Spain.
