MINERAL CONTENT OF NATIVE VEGETABLES OBTAINED BY ENERGY DISPERSIVE XRAY FLUORESCENCE SPECTROMETRY
Journal Title: Journal of Science And Arts - Year 2008, Vol 9, Issue 2
Abstract
In this work the non-destructive methodology based on Energy Dispersive Xray fluorescence (EDXRF) has been applied for the determination of some major and minor elements (K, Ca, Fe, Mn, Cu, Zn) in different vegetation species: [i]Atriplex hortensis, Rumex patientia, Lactuca sativa, Spinacea oleracea [/i]. From data obtained about the mineral content of analyzed samples it could be concluded that all of these plants can be use in supplementary mode as a very high nutritional foodstuffs. The EDXRF measurements were made using the Elvax spectrometer having an X-ray tube with Rh anode and a solid state Si-pin-diode X-ray detector with a 140 μm Be window and 200eV at 5.9 KeV (Fe55 line) energy resolution.

ELECTRON TRANSPORT CHARACTERISTICS OF 6H-SIC AND 4H-SIC FOR HIGH TEMPERATURE DEVICE MODELING
The Monte Carlo method is used to simulate electron transport in bulk würtzite phases of 6H-SiC and 4H-SiC using a three valley analytical band structure. Spherical, non-parabolic conduction band valleys at the , K and...
A PARALLEL ALGORITHM FOR SOLVING TRIDIAGONAL LINEAR SYSTEMS
The coarse-grainded architecture model has been proposed to be a model of iently close existing parallel machines. Under this model we design a communication-efficient parallel algorithm for the solution of tridiagonal l...
ON PARTIAL QUASI-BILINEAR GENERATING FUNCTIONS INVOLVING MODIFIED LAGUERRE POLYNOMIALS
In this note we have shown the existence of more general generating relation from the existence of a partial quasi-bilinear generating relation by using group theoretic method. Some particular cases of interest are also...
A TRIGONOMETRIC METHOD OF SOLVING THE HADWIGER- FINSLER INEQUALITY IN ACUTE TRIANGLE
In the paper [1] the authors proposed the following inequality: In any acute triangle are true the following inequality: ....The aim of this paper is to give a trigonometric proof of the inequality (1)
A NOTE ON THE SCHURER'S CUBATURE FORMULA
Starting with the Schurer's bivariate approximation formula, a cubature formula of Schurer type is constructed. When the approximated function is sufficiently differentiable, an upper bound estimation for the remainder t...
