Four " Protons " were launched between 1965 and 1968.

In addition, the launch pad can supply existing Protons with common hypergol fuels from single sources.

Protons on the SO < sub > 3 </ sub > H ( sulfonic acid ) groups " hop " from one acid site to another.

Protons ( H < sup >+</ sup >) are transported across the proton exchange membrane-often made from Nafion-to the cathode where they react with oxygen to produce water.

Protons are produced by a medical synchrotron or cyclotron, extracting them from proton donor materials and accelerating them in successive travels through a circular, evacuated conduit or cavity, using powerful magnets, until they reach sufficient energy ( usually about 200 MeV ) to enable them to approximately traverse a human body, then stop.

Protons are charged particles and are therefore influenced by magnetic fields.

Protons and electrons bear opposite electrical charges which make them attract each other, and when they are joined they make up an atom of hydrogen -- the basic building block of matter.

Protons are transferred across a series of hydrogen bond s between hydronium ion s and water molecule s.

Protons have a positive charge and a mass 1, 836 times that of the electron, at, although this can be reduced by changes to the energy binding the proton into an atom.

These he interpreted as " negative-energy electrons " and attempted to identify them with protons in his 1930 paper A Theory of Electrons and Protons However, these " negative-energy electrons " turned out to be positrons, and not protons.

Protons bind at various places on the protein, while carbon dioxide binds at the α-amino group.

Protons in different tissues return to their equilibrium state at different relaxation rates.

Protons and neutrons are most important and best known for constituting atomic nuclei, but they can also be found on their own, not part of a larger nucleus.

This is a very important fact in nuclear physics: Protons and neutrons in an atomic nucleus cannot all be in the same quantum state, but instead they spread out into nuclear shells analogous to electron shells in chemistry.

Atomic level – Protons, neutrons, and electrons 4.

Protons translocate across the inner mitochondrial membrane via proton wire.

All Protons are built at the Khrunichev plant in Moscow, and then transported for launch to the Baikonur Cosmodrome, where they are brought to the launch pad horizontally and then raised into vertical position for launch.

However, delays in Angara development mean that Protons will continue to fly for some time.

Protons are generated in an ion source, which can have many different designs.

Protons can also interact with the nucleus of the atoms in the sample through elastic collisions, Rutherford backscattering, often repelling the proton at angles close to 180 degrees.

Protons consist of two up quarks and one down quark, while antiprotons consist of the corresponding antiquarks.

During this short stay at Harvard Wilson published a seminal paper, " Radiological Use of Fast Protons ", which essentially founded the field of Proton therapy.

Protons and neutrons, being distinct types of particles, occupy different quantum states.

Most of my stories were obtained by simply seeking out the person who could give me the facts, and not as a rule by playing clever tricks.

Obviously the commander-in-chief had confidence that Morgan would furnish him good intelligence too, for on the 23rd of May, he told Morgan that the British were prepared to move, perhaps in the night, and asked Morgan to have two of his best horses ready to dispatch to General Smallwood with the intelligence obtained.

It embraced determining when to purchase and when to trade vehicles, who was to drive, when and where repairs were to be made, where gasoline and automobile services were to be obtained and other allied matters.

Measurements at 3.15 cm were obtained on 11 days spread over the interval May 3 to June 19, 1956, using the 50-foot reflector at the U. S. Naval Research Laboratory in Washington.

It is presumed that this negative head was associated with some geometric factor of the assembly, since different readings were obtained with the same fluid and the only apparent difference was the assembly and disassembly of the apparatus.

Background spectra were obtained in all cases.

Spectra were obtained over the temperature range of 77 - 294-degrees-K.

Spectra were obtained from a powdered sample having the shape of a right circular cylinder with a height-to-diameter ratio of 4::

Spectra were also obtained from a sample in a spherical container which was made by blowing a bubble on the end of a capillary glass tube.

Spectra were also obtained from a third sample of Af which had been diluted to three times its original volume with powdered, anhydrous alundum ( Af ).

Serum samples were obtained from normal group A, group B and group O donors.

Approximately 165 fractions were obtained from each column.

Averages of the ratios obtained in a few selected areas were applied to the larger population.

Here again it seems that useful approximations of the size and geographical distribution of the population were obtained in this way in the late pre-war and early post-war periods.

Data were obtained, separately, on three classes of persons: ( A ) residents, present ; ;

For purposes of sample selection only ( individual tests were given later ) we obtained group test scores of reading achievement and intelligence from school records of the entire third-grade population in each school system.

The following efficiencies obtained from JEDEC and RCA specifications were used: Af

The last 10 cases in the investigation of the Nov. 8 election were dismissed yesterday by Acting Judge John M. Karns, who charged that the prosecution obtained evidence `` by unfair and fundamentally illegal means ''.

Colorful agates and other chalcedonies were obtained over 3, 000 years ago from the Achates River, now called Dirillo, in Sicily.

His campaigns were successful and, on 25 July 1139, he obtained an overwhelming victory in the Battle of Ourique, and straight after was unanimously proclaimed King of the Portuguese by his soldiers, establishing his equality in rank to the other realms of the Peninsula.

Research results obtained during that period were not shared between the Axis and the Allied powers during the war.

The name is taken from that of the Amazon River, from which certain green stones were formerly obtained, but it is doubtful whether green feldspar occurs in the Amazon area.

Abba Mari, through Ben Adret's aid, obtained allies eager to take up his cause, among whom were Don Bonafoux Vidal of Barcelona and his brother, Don Crescas Vidal, then in Perpignan.

Whether the motion was due to an irregular distribution of the Earth's atmosphere, thus involving abnormal variations in the refractive index, was also investigated ; here, again, negative results were obtained.
