The first cement to consistently contain alite was made by Joseph Aspdin's son William in the early 1840s.

Johnson ) have claimed precedence in this invention, but recent analysis of both his concrete and raw cement have shown that William Aspdin's product made at Northfleet, Kent was a true alite-based cement.

William Aspdin's innovation was counterintuitive for manufacturers of " artificial cements ", because they required more lime in the mix ( a problem for his father ), a much higher kiln temperature ( and therefore more fuel ), and the resulting clinker was very hard and rapidly wore down the millstones, which were the only available grinding technology of the time.

In 1843, Aspdin's son William improved their cement, which was initially called " Patent Portland cement ", although he had no patent.

Aspdin's works became Robins & Co in 1853, sold on to the Associated Portland Cement Manufacturers ( APCM ) in 1900, which was taken over by the Lafarge Group in 2001.

It was recognized years ago that the transition from daytime to nighttime propagation conditions, and vice versa, is not an instantaneous process, but takes place over periods of time from roughly 2 hours before sunset until about 2 hours after sunset, and again from roughly 2 hours before sunrise until some 2 hours after sunrise.

Such efforts almost always find themselves compelled to ask whether Adam was created capable of growing old and then older and then still older, in short, whether Adam's life was intended to be part of the process of time.

According to this doctrine, the universe was ruled by Heaven, T'ien -- as a natural force, or in the personification of a Supreme Sky-god -- governing all things by means of a process called the Tao, which can be roughly interpreted as `` the Order of the Universe '' or `` the Universal Way ''.

But the process of refusing to think about it was an active reminder in itself and he couldn't rid himself of a consciousness of it throughout the day.

Early anthropology was divided between proponents of unilinealism, who argued that all societies passed through a single evolutionary process, from the most primitive to the most advanced, and various forms of non-lineal theorists, who tended to subscribe to ideas such as diffusionism.

Atari had been in the process of manufacturing another vector game, Lunar Lander, but demand for Asteroids was so high " that several hundred Asteroids games were shipped in Lunar Lander cabinets.

The new element was isolated from its oxides in a complex, multi-step process.

Since the evolution of the Aramaic alphabet out of the Phoenician one was a gradual process, the division of the world's alphabets into those derived from the Phoenician one directly and those derived from Phoenician via Aramaic is somewhat artificial.

This is very similar to the process of osmosis.

In Europe a similar liquid process in open-topped crucibles took place which was probably less efficient than the Roman process and the use of the term tutty by Albertus Magnus in the 13th century suggests influence from Islamic technology.

This was primarily a political strategy designed to give the Conservative party control of the reform process and the subsequent long-term benefits in the Commons, similar to those derived by the Whigs after their 1832 Reform Act.

A similar process is used to break down proteins.

In fact, as their synthesis is controlled by a template directed process in most in vivo systems all biopolymers of a type ( say one specific protein ) are all alike: they all contain the similar sequences and numbers of monomers and thus all have the same mass.

The process for copper is very similar, but the efficiency and kinetics depend on the copper mineralogy.

A similar process happened at about 1 second for electrons and positrons.

In 1995 a similar process could be observed as elsewhere with the production of A Prayer Book for Australia which departed from both the structure and wording of the BCP.

While removing the global clock signal makes the design process considerably more complex in many ways, asynchronous ( or clockless ) designs carry marked advantages in power consumption and heat dissipation in comparison with similar synchronous designs.

An example of this process can be found at Key Length which uses multiple reports to suggest that a symmetric cipher with 128 bits, an asymmetric cipher with 3072 bit keys, and an elliptic curve cipher with 512 bits, all have similar difficulty at present.

Common law ( also known as case law or precedent ) is law developed by judges through decisions of courts and similar tribunals ( as opposed to statutes adopted through the legislative process or regulations issued by the executive branch ).

For alkenes and similar double bonded molecules, the same prioritizing process is followed for the substituents.

In his short story " Crabs on the Island " ( 1958 ) Anatoli Dneprov speculated on the idea that since the replication process is never 100 % accurate, leading to slight differences in the descendants, over several generations of replication the machines would be subjected to evolution similar to that of living organisms.
