Impact of Flooding on Mine Action in Bosnia and Herzegovina, Croatia, and Serbia

Devastating floods swept through Bosnia and Herzegovina, Croatia, and Serbia in May 2014. The destructiveness of the floods, landslides and sediment torrents on minefields resulted in significant environmental and security issues. These three countries’ mine action centers launched a joint project cofunded by the Republic of Croatia’s Ministry of Foreign and European Affairs to develop effective and efficient methods and technologies that might improve the situation. Their research seeks to provide reliable assessments of the flood damage to minefields and generate accurate implications for potential hazardous areas

Citogenotoksična procjena efikasnosti biološke obrade otpadnih voda

The aim of the research was to analyze the cytogenotoxic effects of water samples taken from the biological wastewater treatment. Samples were taken from different stages of of wastewater treatment from the town of Odžak, and from the river Bosna and Sava. As a bioindicator, Allium cepa were used. The lowest value of the mitotic index was recorded at the entry into the purification system (1.9), and the largest on the fertilizer that represents the purification product (16.85). The number of chromosomal aberrations in the purification process decreased by 52.7%. The results indicate that biological wastewater treatment reduces its genotoxic and cytotoxic effects.Cilj istraživanja je bio analizirati citogenotoksični efekat uzoraka vode uzetih sa postrojenja za biološko prečišćavanje komunalnih otpadnih voda. Uzorci su uzeti iz različitih faza obrade sa prečistača vode grada Odžak, te iz rijeka Bosne i Save. Kao bioindikator korištene su lukovice Allium cepa. Najmanja vrijednost mitotičkog indeksa zabilježena je na ulazu u sistem prečišćavanja (1,9%), a najveća na đubrivu koje predstavlja nus-produkt prečišćavanja (16,85%). Broj hromosomskih aberacija se u procesu prečišćavanja smanjio za 52,7%. Rezultati ukazuju na zaključak da se biološkom obradom otpadne vode smanjuje njen genotoksični i citotoksični efekat

Antimikrobna svojstva ekstrakta ploda i lista borovnice, brusnice i aronije

The aim of this paper is to promote antimicrobial activity of berry fruits to rationalize the use of antibiotics considering unwanted consequences and increase of bacteria resistance towards them. In this research we have examined the antimicrobial effects of fruit and leaf extracts of blueberry, cranberry and aronia. During the research we used the Kirby Bauer disc diffusion method. The most prominent antimicrobial effects were achieved by the blueberry fruit extract and cranberry leaf extracts. The aronia extracts have shown the weakest antimicrobial activity. It has been proved that berries posses more antimicrobial effectiveness towards Gramm positive bacteria than the Gramm negative ones.Obzirom na nepoželjne posljedice primjene sintetskih antibiotika, kao i porast bakterijske rezistencije prema njima svrha ovog rada je promocija antimikrobne učinkovitosti bobičastih vrsta sa ciljem racionalizacije upotrebe antibiotika. U ovom istraživanju smo ispitivali antimikrobni učinak ekstrakata iz plodova i listova borovnice, brusnice i aronije. Korišten je disk difuzijski metod po Kirby Baueru. Najizraženiji antimikrobni učinak od ispitivanih plodova posjeduje plod borovnice, a od listova list brusnice. Ekstrakti iz aronije iskazuju slabu antimikrobnu aktivnost. Bobičaste vrste su antimikrobno djelotvornije prema Gramm pozitivnim bakterijama u odnosu na Gramm negativne
