On the near pseudo Smarandache function [PDF]
The main purpose of this paper is using the elementary method to study the calculating problem of an infinite series involving the near pseudo Smarandache function K(n), and give an exact calculating ...

Polytropic spheres modelling dark matter haloes of dwarf galaxies [PDF]
Context. Dwarf galaxies and their dark matter (DM) haloes have velocity curves of a different character than those in large galaxies. These velocity curves are modelled by a simple pseudo-isothermal model containing only two parameters, which do not give

Surfaces in a pseudo-sphere with harmonic or 1-type pseudo-spherical Gauss map [PDF]
We give a complete classification of Riemannian and Lorentzian surfaces of arbitrary codimension in a pseudo-sphere whose pseudo-spherical Gauss maps are of 1-type or, in particular, harmonic. In some cases a concrete global classification is obtained, while in other cases the solutions are described by an explicit system of partial differential ...

Pseudo-Smarandache Functions of First and Second Kind [PDF]
In this paper we define two kinds of pseudo-Smarandache functions. We have investigated more than fifty terms of each pseudo-Smarandache function.

Devolatilization of Polypropylene Particles in Fluidized Bed
Gasification of plastic waste is an emerging technology of particular interest to the scientific world given the production of a hydrogen-rich gas from waste material. Devolatilization is a first step thermochemical decomposition process which is crucial

Soliton solution to the time-like curve shortening flow in the pseudo-sphere
Abstract A time-like curve on the unit pseudo-sphere can be a solition solution to the time-like curve shortening flow We first introduce the sufficient conditions for it to hold. And by studying the properties of the structure function of non-geodesic curves, I deduce some conditions to be satisfied by the structure function of non ...
