The purpose of this paper is to introduce a new generalized inverse, called DMP inverse, associated with a square complex matrix using its Drazin and Moore-Penrose inverses. DMP inverse extends the notion of core inverse, introduced by O.M. Baksalary and G. Trenkler for matrices of index at most 1 in [Core inverse of matrices, Linear and Multilinear Algebra, 2010, 681–697] to matrices of an arb...

High-resolution scanning electron microscopy (HR-SEM) with backscattered electrons (BSE) under a low accelerating voltage provided images with compositional information about Pt nano-particles with a diameter of approximately 6 nm that were dispersed in mesoporous silica (SBA-15). The dispersion of Pt nano-particles in mesoporous silica was investigated using the BSE imaging method in combinati...

Changes in the mechanical properties of granular materials, induced by variations intrinsic compressibility particles, are investigated means numerical simulations based on combination Finite Element and Contact Dynamics methods. Assemblies athermal 2D particles subjected to quasi-static uni-axial compactions up packing fractions close $1$. Inspired contact mechanics Hertz's limit, we show that...

Objective:At the present study, relationship between phagocytosis of PLGA particles and combined effects of particle size and surface PEGylation was investigated.  Materials and Methods:Microspheres and nanospheres (3500 nm and 700 nm) were prepared from three types of PLGA polymers (non-PEGylated and PEGylation percents of 9% and 15%). These particles were prepared by solvent evaporation metho...

The chemical composition of kelps (e.g. polyphenolics) deters grazing by herbivores, but kelp detritus is potentially a source of nutrition for suspension feeders. The effects of kelp detritus derived from two species [Agarum fimbriatum Harvey and Costaria costata (Turner) Saunders] on feeding of oysters, Crassostrea gigas Thunberg, and mussels, Mytilus trossulus Gould, were examined in feeding...

objective(s): the silver nanoparticles, being very small size, can permeate the cellular membrane and interfere in the cell's natural process. in the present study, the effects of time, the dosage of these particles and their use on blood molecules and hormones, the volume of drinking water, and the urine parameters were analyzed.materials and methods: thirty six rats of the wistar race, as sub...

the presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. the aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coefficie...

In this paper we present a sufficient condition for the validity of a discrete maximum principle (DMP) for a class of elliptic problems of the second order with a nondiagonal coefficient matrix, solved by means of linear finite elements (FEs). Numerical tests are presented.
