( At lower photon energies a characteristic structure with edges appears, K edge, L edges, M edges, etc.

* At low energies, the logic of the renormalization group tells us that, despite the unknown choices of these infinitely many parameters, quantum gravity will reduce to the usual Einstein theory of general relativity.

At the energies reached in current experiments, these strings are indistinguishable from point-like particles, but, crucially, different modes of oscillation of one and the same type of fundamental string appear as particles with different ( electric and other ) charges.

At low-beam energies, the best resolution ( by 2009 ) is achieved by the Magellan XHR system from FEI Company ( 0. 9 nm at 1 kV ).

At energies near and beyond the mass of the carriers of the weak force, the W and Z bosons, the strength of the weak force becomes comparable with electromagnetism.

At very high densities, where most of the particles are forced into quantum states with relativistic energies, the pressure is given by < span style =" white-space: nowrap "> P = K '( n / V ),</ span > where K ' again depends on the properties of the particles making up the gas.

* At sufficiently large energies, the strong interaction between quarks can be described by the exchange of virtual gluons.

At energies much greater than 100 GeV all these particles behave in a similar manner.

At a spallation source, the time of flight technique is used to sort the energies of the incident neutrons ( higher energy neutrons are faster ), so no monochromator is needed, but rather a series of aperture elements synchronized to filter neutron pulses with the desired wavelength.

At low energies ( around 20 eV ), the interactions between the electrons and the analyte molecules do not transfer enough energy to cause ionization.

At higher energies, the de Broglie wavelength of the electrons becomes smaller than the bond lengths in typical analytes ; the molecules then become " transparent " to the electrons and ionization efficiency decreases.

At electron energies of 10keV, a chamber pressure of 10 < sup >− 5 </ sup > mbar or lower is necessary to prevent significant scattering of electrons by the background gas.

At that time, when the Union was done and personalities of fresh energies and cultured people were needed, people who were educated in Western Universities, Titu Maiorescu had an early ascent, from his youth, as he was a University professor at 22 years old ( in Iaşi ), a dean at 23 and a rector at the same age, then he became an academician ( member of the Romanian Academic Society ) at 27, a deputy at 30, then a minister at age 34.

At the heart of the issue was the teaching of the Essence-Energies distinctions ( which states that while creation can never know God's uncreated essence, it can know His uncreated energies ) by Gregory Palamas.

At low energies, type I string theory is described by the N = 1 supergravity ( type I supergravity ) in ten dimensions coupled to the SO ( 32 ) supersymmetric Yang-Mills theory.

At low energies, type IIA string theory is described by type IIA supergravity in ten dimensions which is a non-chiral theory ( i. e. left-right symmetric ) with ( 1, 1 ) d = 10 supersymmetry ; the fact that the anomalies in this theory cancel is therefore trivial.

At low energies, type IIB string theory is described by type IIB supergravity in ten dimensions which is a chiral theory ( left-right asymmetric ) with ( 2, 0 ) d = 10 supersymmetry ; the fact that the anomalies in this theory cancel is therefore nontrivial.

At the end of the events of " The Next Life ", the Doctor and his companions escaped the timeless Divergent universe-Rassilon having previously filtered the Zagreus energies out of the Doctor upon his arrival in this universe without the Doctor's knowledge -, but Rassilon and the Kro ' Ka remained trapped in a permanent loop.

At the very first, then, Brumidi was required, by the classically pyramidal shape of his central group, to fill in the triangular space above the seated girl on Liberty's right, before starting on the allegorical figures themselves.

At its most ecstatic moments, husband and wife are elevated far above worldly cares.

At pH values greater than the pKa of the carboxylic acid group ( mean for the 20 common amino acids is about 2. 2, see the table of amino acid structures above ), the negative carboxylate ion predominates.

At the suggestion of his friend Benjamin Ruff, Carnegie's partner Henry Clay Frick had formed the exclusive South Fork Fishing and Hunting Club high above Johnstown, Pennsylvania.

At above the valley floor, the pair were at the highest elevation above the Lunar Module of any other Apollo mission.

At Athens, the traveller Pausanias was informed in the second-century CE that the cult of Aphrodite Urania above the Kerameikos was so ancient that it had been established by Aegeus, whose sisters were barren, and he still childless himself.

At the above mentioned turns ( Kandilli and Yenikoy ) where significant course alterations have to be made, the rear and forward sights are totally blocked prior to and during the course alteration.

At the time, before the pre-eminence of Mozart or Beethoven, and with Johann Sebastian Bach known primarily to connoisseurs of keyboard music, Haydn reached a place in music that set him above all other composers except perhaps George Frideric Handel.

At its source, the river is at an elevation of above sea level.

At a price above equilibrium, there is a surplus of quantity supplied compared to quantity demanded.

At the end of the algorithm, if the Gauss – Jordan elimination ( zeros under and above the leading 1 ) is applied:

At first Germany's military moves were brilliantly successful, as in the " blitzkrieg " invasions of Poland ( 1939 ), Norway ( 1940 ), the Low Countries ( 1940 ), and above all the stunningly successful invasion and quick conquest of France in 1940.

At higher latitudes in summer, when the sun does not sink below the horizon, a day is counted from midday to midday, and in the winter, when the sun does not rise above the horizon, from midnight to midnight.

At a level above that of LAU is the Region which clusters counties together for NUTS purposes.

At a pH below their pI, proteins carry a net positive charge ; above their pI they carry a net negative charge.

At the same time as the generation of the gynogenetic and androgenetic embryos discussed above, mouse embryos were also being generated that contained only small regions that were derived from either a paternal or maternal source.

At the same time, Falwell's legacy regarding homosexuality is complicated by his support for LGBT civil rights ( see " civil rights " section above ), as well as his efforts at reconciliation with the LGBT community in later years.

At this moment he was unfortunately called out by a person on business from Porlock, and detained by him above an hour, and on his return to his room, found, to his no small surprise and mortification, that though he still retained some vague and dim recollection of the general purport of the vision, yet, with the exception of some eight or ten scattered lines and images, all the rest had passed away like the images on the surface of a stream into which a stone had been cast, but, alas!

The passage continues with a famous account of an interruption: " At this moment he was unfortunately called out by a person on business from Porlock, and detained by him above an hour, and on his return to his room, found, to his no small surprise and mortification, that though he still retained some vague and dim recollection of the general purpose of the vision, yet, with the exception of some eight or ten scattered lines and images, all the rest had passed away like the images on the surface of a stream into which a stone has been cast, but, alas!

At some of the mithraeums which have been found below churches, for example the Santa Prisca mithraeum and the San Clemente mithraeum, the ground plan of the church above was made in a way to symbolize Christianity's domination of Mithraism.

At 10-15 kilometers ( 6 – 9 miles ) above the Earth's surface, the absorption of sunlight would further heat the smoke, lifting some, or all of it, into the stratosphere, to where the smoke would persist for years, with no rain to wash it out.
