Chemical properties and decay resistance of eucalyptus grandis wood from steamed logs
The objective of this study was evaluate the effect of the log steaming on the chemical properties and decay resistance of Eucalyptus grandis wood. Logs with diameter between 20 and 22 cm were studied. Half of logs were ...
Decay chain differential equations: Solution through matrix algebra
(ELSEVIER SCIENCE BV, 2010)
A matricial method to solve the decay chain differential equations system is presented. The quantity of each nuclide in the chain at a time t may be evaluated by analytical expressions obtained in a simple way using ...
Nonmesonic weak decay of charmed hypernuclei
(Iop Publishing Ltd, 2018-01-01)
We present a study of the nonmesonic weak decay (NMWD) of charmed hypernuclei using a relativistic formalism. We work within the framework of the independent particle shell model and employ a (pi, K) one-meson-exchange ...
Probing the quenching of gA by single and double beta decays
Ground-state-to-ground-state two-neutrino double beta (2νββ) decays and single beta (EC and β−) decays are studied for the A=100 (100Mo100Tc100Ru), A=116 (116Cd116In116Sn) and A=128 (128Te128I128Xe) nuclear systems by using ...
New parametric decays of proton beam-plasma electromagnetic waves
(Blackwell Publishing Ltd, 2002)
Ion beam-plasma interactions are the source of wave activity in several space environments. Therefore the study of these waves and their parametric decays are very important in space physics. Thus we study parametric decays ...
NONLEPTONIC ANNIHILATION DECAYS of B MESON WITH A NATURAL INFRARED CUTOFF
(World Scientific Publ Co Pte Ltd, 2009-09-10)
Within the QCD factorization approach we compute the amplitudes for pure annihilation channels of B mesons decays into final states containing two pseudoscalar particles. These decays may be plagued by effects like ...
Decay of Batchelor and Saffman rotating turbulence
(American Physical Society, 2012-12)
The decay rate of isotropic and homogeneous turbulence is known to be affected by the large-scale spectrum of the initial perturbations, associated with at least two canonical self-preserving solutions of the von Kármán-Howarth ...
Effect of Helicity and Rotation on the Free Decay of Turbulent Flows
(American Physical Society, 2009-06)
The self-similar decay of energy in a turbulent flow is studied in direct numerical simulations with and without rotation. Two initial conditions are considered: one nonhelical (mirror symmetric) and one with maximal ...
