Soil Organic Carbon (SOC) is one of the key indicators of land degradation. SOC positively affects soil functions with regard to habitats, biological diversity and soil fertility; therefore, a reduction in the SOC stock of soil results in degradation, and it may also have potential negative effects… |

Precise knowledge of X-ray diffraction profile shape is crucial in the investigation of the properties of matter in crystals powder.
Line-broadening analysis is the fourth pre-processing step in most of the full powder pattern fitting softwares. The final result of
line-broadening analysis strongly… |

We propose a numerical method to solve the Wigner equation in quantum systems of spinless, non-relativistic particles. The method uses a spectral decomposition into L-2(R-d) basis functions in momentum-space to obtain a system of first-order advection-reaction equations. The resulting equations are… |

We consider the Cauchy problem for the 2 x 2 nonstrictly hyperbolic system [...] For possiblylarge, discontinuous and resonant data, the generalized solution to the Riemann problem is introduced, interaction estimates are carried out using an original change of
variables and the convergence of… |

Spectral emissivity is a key property of the Earth surface of which only very few measurements exist so far in the far-infrared (FIR) spectral region, even though recent work has shown its FIR contribution is important for accurate modelling of global climate. The European Space Agency's 9th Earth… |

We introduce a mesoscopic three-dimensional lattice Boltzmann model which attempts to mimic the physical features associated with cage effects in dynamically heterogeneous fluids. To this purpose, we extend the standard lattice Boltzmann dynamics with self-consistent constraints based on the… |

In the present paper, the analysis of the turning capability of the naval supply vessel presented in Part I
(Broglia et al., 2015) is continued with different stern appendages, namely twin rudder and centreline skeg.
The main purpose of the analysis is to assess the capability of an in-house CFD… |

We provide a general approach to deal with entropy solutions to scalar conservation laws presenting nonclassical shocks. |

We employ Lyapunov functions to study boundedness and stability of dynamic equations
on time scales. Most of our Lyapunov functions involve the term |x| and its ?-derivative.
In particular, we prove general theorems regarding qualitative analysis of solutions of delay
dynamical systems and then use… |

We give a Sobolev inequality with the weight K(x) belonging to the class A_2\cap G_n for the
function |u|^t and the weight K(x)^{-1} for |u|^2. The constant in the relevant inequality is
seen to depend on the G_n and A_2 constants of the weight. |
