Three Schiff bases were synthesized by reaction of different benzaldehydes with amino acids. The characterization of these compounds was performed using IR spectroscopy, molecular calculations, thin-layer chromatography, determining the melting point and other physical characteristics. IR spectra for imino groups (C=N), which are characteristic of Schiff bases, show stretching frequency from 1629 to 1654 cm-1. The obtained spectral results were confirmed by molecular calculations using the density functional theory (DFT) and were performed before experimental work. The DFT global chemical reactivity descriptors were calculated and used to predict their relative stability and reactivity of synthesized compounds. The antimicrobial assay of all compounds were screened for Grampositive bacteria species: Staphylococcus aureus ATCC 25923; Methicillin-resistant Staphylococcus aureus: MRSA ATCC 33591; Bacillus subtilis ATCC 6633; and Enterococcus faecalis ATCC 29212, Gram-negative: Salmonella enterica ATCC 31194; Pseudomonas aeruginosa ATCC 9027; Escherichia coli ATCC 25922; Extended Spectrum Beta-Lactamase producing E. coli: ESBL E. coli ATCC 35218, and one yeast Candida albicans ATCC 1023.The highest values of inhibition zones were recorded for compound1, followed by the compound 3, while compound 2 performed inhibitory effect just in case of MRSA. DFT calculations show that antimicrobial activity has a good correlation with chemical reactivity descriptors obtained Schiff bases.

Safety-critical systems are those systems whose malfunctioning can result in harm or loss of human life, or damage to property or the environment. Such systems usually need to comply with a domain- ...

In the focus of this paper are some issues of the role of an authorized prosecutor in the pre-criminal and criminal proceedings. For the purpose of calling the prosecutor, s activity, the function of the charge or the function of prosecution, the author reverses in favor of this last. One part of the paper is devoted to the analysis and riticism of some unacceptable definitions of the prosecution function. The author states that the prosecution function consists of a pre-processing and process part. The prosecution function was also considered through the prism of certain historical types of criminal proceedings, as well as through the prism of certain authorized prosecutors.
