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.

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

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.

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.

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

In 2000, physicists first observed a new type of radioactive decay in which a nucleus emits two protons at once-perhaps a nucleus .< ref > Decay of a Resonance in < sup > 18 </ sup > Ne by the Simultaneous Emission of Two Protons, Physical Review Letters vol. 86, p. 43-46 ( 2001 ), by J. Gómez del Campo, A. Galindo-Uribarri et al .</ ref > The team led by Alfredo Galindo-Uribarri of the Oak Ridge National Laboratory announced that the discovery will help scientists understand the strong nuclear force and provide fresh insights into the creation of elements inside stars.

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.

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

Protons on a molecule that are acidic, even only slightly, can be exchanged for a metal by a suitable butyllithium reagent mixture.

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

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.

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.

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.

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

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

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

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

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

Directors cannot, without the consent of the company, fetter their discretion in relation to the exercise of their powers, and cannot bind themselves to vote in a particular way at future board meetings.

Hemoglobin deficiency can be caused either by decreased amount of hemoglobin molecules, as in anemia, or by decreased ability of each molecule to bind oxygen at the same partial pressure of oxygen.

Lubricants may contain additives known as friction modifiers that chemically bind to metal surfaces to reduce surface friction even when there is insufficient bulk lubricant present for hydrodynamic lubrication, e. g. protecting the valve train in a car engine at startup.

Spindle fibers bind to the centromeres of each pair of homologs and arrange the pairs at the spindle equator.

Morphine is a rapid-acting narcotic, and it is known to bind very strongly to the μ-opioid receptors, and for this reason, it often has a higher incidence of euphoria / dysphoria, respiratory depression, sedation, pruritus, tolerance, and physical and psychological dependence when compared to other opioids at equianalgesic doses.

When they encounter an infection site the particles gain a positive charge provoked by the slightly acidic environment at the infection sites, allowing them to bind to the negatively charged bacterial cell walls and release antibiotics at locally high concentration.

Protein binding can be extraordinarily tight and specific ; for example, the ribonuclease inhibitor protein binds to human angiogenin with a sub-femtomolar dissociation constant (< 10 < sup >− 15 </ sup > M ) but does not bind at all to its amphibian homolog onconase (> 1 M ).

This uniformity can be explained by detailed fluid-mechanical modelling, which shows that the resist moves much faster at the top of the layer than at the bottom, where viscous forces bind the resist to the wafer surface.

In 1992, Wafik El-Deiry when he was working with Bert Vogelstein at Johns Hopkins University identified the consensus sequence, to which human p53 could bind, by immunoprecipitating human genomic DNA that could be bound by baculovirus-produced human p53 protein.

TIM50 is bound to TIM23 at the inner mitochondrial side and found to bind presequences.

Sabbath ordinances were appealed to, with the idea that only the word of God can bind men's consciences in whether or how they will take a break from work, or to impose an obligation to meet at a particular time.

Some people define narcotics as substances that bind at opioid receptors ( cellular membrane proteins activated by substances like heroin or morphine ) while others refer to any illicit substance as a narcotic.

Because it normally has a positively charged nitrogen at its end, lysine can bind the negatively charged phosphates of the DNA backbone.

Once at the ER, IP < sub > 3 </ sub > is able to bind to a the Ins3PR receptor on a ligand-gated Ca < sup > 2 +</ sup > channel that is found on the surface of the ER.

β-Lactams cannot bind as effectively to these altered PBPs, and, as a result, the β-lactams are less effective at disrupting cell wall synthesis.

This allows quick and easy fitting and provides a snug and comfortable diaper fit that will neither bind nor wad on the infant … as a result of this snugger fit obtained because of this fold configuration, the diaper is less likely to leak or, in other words, its containment characteristics are greatly enhanced .” Further developments in diaper design were made, such as the introduction of refastenable tapes, the " hourglass shape " so as to reduce bulk at the crotch area, and the 1984 introduction of super-absorbent material from polymers known as sodium polyacrylate that were originally developed in 1966.

Similarly, organismal form can be influenced by mutations in promoter regions of genes, those DNA sequences at which the products of some genes bind to and control the activity of the same or other genes, not only protein-specifying sequences.

In the prose section at the end of Lokasenna, the gods catch Loki and bind him with the innards of his son Nari, while they turn his son Narfi into a wolf.

Bride-favours, anciently called bride-lace, were at first pieces of gold, silk or other lace, used to bind up the sprigs of rosemary formerly worn at weddings.
