combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen meq,milliequivalent- one-thousandth of an equivalent
atomic mass,the mass of a singleatom, usually expressed inatomic mass units(amu). Most of the mass of an atom is concentrated in the protons and neutrons contained in the nucleus. Each proton or neutron weighs about 1 amu, and thus the atomic mass is always very close to themass number...
nucleus. The number below the symbol is the atomic mass, which is the weight of the atom; this is the sum of the number of protons and neutrons. For example, hydrogen, the first element in the periodic table, has an atomic number of 1 and an atomic mass of 1.00794 atomic mass unit ...
actually refer to unified atomic mass units or u. For standardization a specific atomic nucleus (carbon-12 vs. oxygen-16) had to be chosen because average mass of a nucleon depends on the count of the nucleons in the atomic nucleus due to mass defect. This is also why the mass of a ...
[16]. The CCS measurements for these oligomers indicated a sheet-like structure, in comparison with the less compact measurements obtained for a range ofglobular proteinsof similar molecular mass. From these data, the authors proposed that the capsid assembly process begins with a nucleus exhibiting...
(eq 4) where σpe is the atomic photoeffect cross section, σcoh and σincoh are the coherent (Rayleigh) and the incoherent (Compton) scattering cross sections, respectively, σpair and σtrip are the cross sections for electron-positron production in the fields of the nucleus and of the ...
Phys. J. A (2024) 60:104 Page 5 of 9 104 Table 1 Transition from the ground state of the parent nucleus 77As to the excited state of the daughter 77Se. The first and second columns illustrate the experimental spin-parity of the initial ground state and its half-life. The third ...
Dephosphorylated NFAT translocates to the nucleus and upregulates slow fiber specific gene expression. By contrast, decreased activation of calcineurin promotes the transition of slow-to-fast myofibers31,32. Metabolite utilization also varies depending on the types of fibers present in the muscle. Type...
which achieves relative mass uncertainties of the order of 10−11. However, redundancy checks using data from different experiments reveal considerable inconsistencies in the masses of the proton, the deuteron and the helion (the nucleus of helium-3), suggesting that the uncertainty of these values...
