Predicting ash basicity from its density
Coke and Chemistry, 2010Physical determination of the chemical composition and actual density of the ash in coal and coal batch reveals that they are statistically related, as confirmed by high values of the multiple-correlation and determination coefficients. The proposed method of determining the actual density of the ash in coal and batch permits significantly more rapid ...

Basic principles of electron density fluctuations in a plasma
Plasma Physics, 1977The collective fluctuation spectrum of the electron density in a plasma is calculated by a method which does not utilize a specific kinetic equation, and relies only on the following three very general principles: the linear response of a plasma to a weak electric field, the Nyquist theorem, and the principle of causality in the form of the Hilbert ...

Basic Density-Functional Theory an Overview
Physica Scripta, 2004In these notes I have given a personally flavored exposeof static density- functional theory (DFT). I have started from standard many-body physics at a very elementary level and then gradually introduced the basic concepts of DFT. Successively more advanced topics are added and at the end I even discuss a few not yet published theories.

Level densities for basic and applied nuclear physics
Radiation Effects, 1986Abstract Nuclear level densities are a key ingredient in compound nuclear reaction calculations. They are, therefore, of importance to fields as diverse as fission and fusion reactor design and astrophysics. A review of present methods for calculating level densities is presented, which includes global approximation methods and rotational enhancement ...

Isotonic estimators of monotone densities and distribution functions: basic facts
Statistica Neerlandica, 1993We present short proofs of some basic results from isotonic regression theory. A straightforward argument is given to show that the left continuous version of the concave majorant of the empirical distribution function maximizes the likelihood function f↦f(X,)…f(Xn) within the class of non‐increasing densities.

Simulation of lipid peroxidation in low density lipoprotein by a basic “skeleton” of reactions
Atherosclerosis, 1995A minimal kinetic model describing lipid peroxidation in low-density lipoprotein (LDL) has been set up. Models have been calculated by numeric integration of the differential equations describing this system consisting of seven reactions and eleven reactants in a single compartment.

Density functional computations of proton affinity and gas‐phase basicity of proline
Journal of Mass Spectrometry, 2001AbstractAn Erratum has been published for this article in Journal of Mass Spectrometry 37(2) 2002, 232.The proton affinity and gas‐phase basicity of proline were evaluated by using density functional theory coupling the B3‐LYP hybrid functional with the extended 6–311++G** basis set.

Analysis of basic factors governing compacted powder density
Russian Journal of Non-Ferrous Metals, 2011Based on a theoretical analysis of the behavior of metal powders during compaction, basic factors governing the compacted powder density, i.e., the compaction pressure and the sizes of a powder particle and its grain, are determined. Mechanisms of the effect of these factors are considered, and a mathematical dependence for forecasting the compacted ...

Calculation for density of molten slags using optical basicity
Ironmaking & Steelmaking, 2013AbstractA model for density calculation of multicomponent slags was developed in the present work. This model is an extension of a previous model proposed by the present author. Density values of molten slags were calculated from molar volume values, which were calculated from molar volume of pure component and mixing molar volume.
