Abstract Background: Social networks allow real-time interaction that enhances a bank’s ability to respond to customers in a timely, intuitive and personalized manner. By using social networks, banks can improve the understanding of their clients and bank’s products they need. Also, banks can enhance relations with clients and strengthen their brand through raising client loyalty. Objectives: The paper explores and analyses the current presence of banks in Bosnia and Herzegovina on social networks. Methods/Approach: The paper studies the presence of 24 banks in Bosnia and Herzegovina on social networks and analyses the basic characteristics of profiles/pages of the banks on the most popular social networks. Results: A half of the banks have their profiles/pages on different social networks (mostly on Facebook and YouTube). They use the profiles/pages mainly for content marketing, i.e. for presenting their business operations. Unfortunately, banks do not encourage interaction with clients, except through likes. Conclusions: The analysis does not show that banks have a systematized and planned appearance on social networks. There is a plenty of room for improvement, and it is necessary primarily to address the interaction between clients and banks through social networks.

The aim of this study was to determine the total phenolic content, evaluate antioxidant propertie and antimicrobial potential, and identify phenolic compounds in alcoholic and aqueous extracts of the wild cherry (Prunus avium L.) stems collected in Bosnia and Herzegovina. Alcoholic extracts had higher contents of phenolic and flavonoid components, as well as the antioxidant and ferric reducing antioxidant capacity in comparison to aqueous extracts. All extracts were characterized by HPLC analysis. Furthermore, for the first time, the antimicrobial properties of wild cherry stem extracts were evaluated. Quercetin and (+)-catechin were the main compounds identified in the alcoholic extract, followed by chlorogenic acid and rutin. Quercetin was also the major component detected in aqueous extracts. Besides, alcoholic extract showed better antibacterial properties against Staphylococcus aureus as a representative gram-positive bacteria than infusion, whereas none of the samples showed antibacterial activity against Escherichia coli and fungus Candida albicans.

Environmental care, higher requirements for quality of effluent, high cost of conventional wastewater treatment, and increased energy costs required for their work, have led scientists to more comprehensive research on a possibility of using a constructed wetland in wastewater treatment technology. Constructed wetlands are artificially shaped swamps with the aim of creating conditions conducive to the purification of wastewaters flowing through them. They are used for treatment of municipal wastewater from small settlements and a small industrial facility, as well as other types of wastewater. The educational pilot scale constructed wetland on which the research was conducted is located in the area of Bihać municipality, on a plot used by the Biotechnical Faculty in Bihać. The pilot scale constructed wetland for wastewater treatment covers an area of 20 m2 and is dimensioned for 10 equivalents of population. In this research we have examined the effectiveness of domestic wastewater treatment in the "Grmeč" Teaching Center using pilot scale constructed wetland. Plants planted in the constructed wetland were Typha latifolia and Phragmites australis, and the substrate was made of sand and pebbles of different granulations. The recipient of purified wastewater is the Drobnica stream, which is about 10 m away from the site. The research was conducted in May, with the flow varied depending on a weekly student workload. Efficiency of purification using constructed wetland depended on flow rate and organic wastewater load, ranging from 37.15% at a minimum flow of 9.89x10-6 m3/s and HPK values of 35 mgO2/L, up to 89.48% at the highest flow value of 2.51x10-5 m3/s, and HPK values of 189 mgO2/L. The highest concentration of ammonia in the influent was 145.62 mg N/L, and the lowest concentration of ammonia in the effluent was 6.31. mg N/L.

: Aim: Evaluation of the significance of micronuclei (MN) as biomarkers for evaluation the risk of malignant transformation in uterine cervix. MN are intracytoplasmic inclusion bodies from chromatin fragments or whole chromosomes. Their presence in cells is a reflection of chromosomal aberration during cellular mitosis. Patients and methods: MN screening was done in all selected cytopathological smears (conventional Papanicolaou test) by counting 1000 cervical squamous cells with a light microscope at a magnification of 1000x. Results: Comparisons between women with progressive increases in cervical intraepithelial neoplasia (CIN) and control group. The MN frequencies observed were significantly higher in the groups with cellular changes compared to the control group. Conclusion: The results described that the MN test in cervix smears could be incorporated into routine screening procedures as an additional criterion for early detection of cytopathologocal damage. However, additional detailed, systematic studies are needed to confirm this suggestion.
