Calcium phosphate, Ca3(PO4)2, is an ionic compound and a common anti-caking agent added to food products. What is the formula mass (amu) of calcium phosphate? Answer:310.18 amu The Mole The identity of a substance is defined not only by the types of atoms or ions it contains, but by...
An extension of the Weizscker mass formula is proposed for the simultaneous description of normal (i.e. non-strange) nuclei and {LAMBDA} hypernuclei. The mass formula is inspired by the spin–flavour SU(6) symmetry of Gürsey and Radicati and includes a Majorana term. Available masses of ...
The goldstino of spontaneously broken supersymmetry develops a mass in the presence of perturbations which violate supersymmetry explicitly. In analogy to the chiral dynamics of pions, the general current algebra formula for this mass is derived. It is verified and illustrated in simple models at ...
摘要: In this paper, we study negacyclic codes of length 2 k over the ring [equation], u2 = 0. We have obtained a mass formula for the number of negacyclic of length 2 k over R. We have also determined the...关键词: 94B05 94B60 Codes over ź4+uź4$\mathbb {Z}_{4}+u...
In this paper we derive a formula for the post-gelation mass for the case of a separable bilinear kernel K ( λ , μ ) = θ ( λ ) θ ( μ ), and investigate the asymptotic behaviour of the solution.关键词: Coagulation Gelation ...
Mass formula for 3He clusters We have obtained an analytic expression for the total energy of He clusters composed of N atoms. It is a variational solution of an energy density functional, where the extended Thomas-Fermi method has been used for the kinetic-energy de... F Castaño,M Membr...
It has been shown by one of the authors1 that in isotropic spherical coordinates there is a relation between the mass of a static spherical gravitating body and the pressure distribution inside it. In this paper the result is generalized for the case of stationary axisymmetric configurations.关键...
XAFSmass XAFSmass is a python program for calculating the mass of XAFS [X-ray Absorption Fine Structure] samples. The chemical formula parser understands parentheses and weight percentage, also in nested form. XAFSmass reports the quantity (weight, thickness or pressure) together with the expected...
In this paper it is shown that the mass density ρ (x) in the differential equation is related to the trace, tr(x)=∑(1/λ n (x)), by the formula ρ(x)=tr '' +(2/x)tr ' · More precisely, this formula for ρ is proved to hold if ρ is positive, has a continuous ...
