QUALITATIVE AND QUANTITATIVE CONTENT DETERMINATION OF MACRO-MINOR ELEMENTS IN BRYONIA ALBA L. ROOTS USING FLAME ATOMIC ABSORPTION SPECTROSCOPY TECHNIQUE

Purpose: To determine the elements in Bryonia alba L.roots, collected from the Crimean Peninsula region in Ukraine.Methods: Dry ashing was used as a flexible method and all elements were determined whirlwind multi selector using atomic absorption spectrometry (AAS) equipped with flame and graphite furnace.Results: The average concentrations of the

A vector-matrix approach to the theoretical design of metabolic pathways converting chemical compounds, viz., preset substrates, into desirable products is described.It is a mathematical basis for computer-aided generation of alternative biochemical reaction sets executing the given substrate-product conversion.The pathways are retrieved from the u

We show how machine ceiling fan with 18 inch downrod learning techniques can be applied for the classification of topological phases in finite leaky photonic lattices using limited measurement data.We propose an approach based solely on a single real-space bulk intensity image, thus exempt from complicated phase retrieval procedures.In particular,
