Traduction de poèmes de Miroslav Antić

Présentation Décrire en quelques lignes la vie et l'œuvre de Miroslav Antić (1932-1986) semble relever d'une gageure, tant son activité fut incessante et se déploya dans de multiples directions, comme il le confessait lui-même : J’ai fait n’importe quoi. J’ai été aide-maçon, ouvrier dans une brasserie, docker, marin, metteur en scène, je me suis occupé de plomberie et de canalisations, travaillé avec des compresseurs, façonné du bois, je sais construire un toit, j’ai joué dans un théâtre de m..

Drinking water quality in city of Banja Luka, Bosnia and Herzegovina : case study

The paper presents the situation of system for public drinking water facilities “Waterworks” of Banja Luka city, including the current situation and new projects and facilities. The goal of the case study is to analyse and evaluate the results of basic physicochemical parameters of drinking water produced during the period of two years – 2013 and 2014. The data includes the seasonal sampling champagnes of two years, during the months January, April, Jul and October. It is important to have continual and controlled monitoring and evaluation of the wells, raw water wells and drinking water quality therefore it can be affected under negative impact of the dynamic natural change and anthropogenic activities. According to basic physicochemical parameters the population of Banja Luka is drinking water of good quality. During the research correlation and covariance of basic physicochemical parameters was evaluated

Removal of As(III) from Water Using “Green” Synthetized Zero Valent Iron in the Presence of Competing Phosphate Ions

Nanoscale zero valent iron (nZVI) has been widely investigated for treatment of environmental contaminants. Various technologies are currently available to remove As(III) and phosphate from aqueous environment, but among them, adsorption is most common because its simplicity, treatment stability and cost effectiveness. This study is focused on the removal efficiency of As(III) in the presence of competing phosphate ions by nZVI synthesized using polyphenols from oak and mulberry leaf extracts producing OAK-nZVI and M-nZVI, respectively. The highest removal efficiency of As(III) was obtained for M-nZVI (up to 91% at all nZVI doses). 87% removal was obtained for OAK-nZVI. The same conclusion could be retrieved in the case of PO43− removal (the highest removal, up to 78% at all nZVI doses for M-nZVI). Concerning OAK-nZVI, removal efficiencies increased with increasing nZVI doses (21–76% for doses 2–16 mL). Adsorption of As(III) in the presence of competing PO43− ions on M-nZVI, decreased from 91% to 79%. On OAK-nZVI material, significant changes could not be observed. One can conclude that the presence of PO43− ions in arsenic aqueous solutions would reduce effectiveness of the M-nZVI for As(III) remediation. This conclusion was supported by the fact that M-nZVI particles had a greater antioxidative capacity in comparison to OAK-nZVI which directly influenced nanoparticles synthesis and stability
