The main purpose of this study was to investigate whether the length of sentences has influence on the frequency of speech disfluencies for children who stutter. The participants included 30 children who stutter 19 male participants and 13 female participants, whose age ranged between 4 years and 8 months to 6 years and 11 months (56 to 83 months of age). Research was conducted in kindergartens and primary schools in Tuzla Canton in Bosnia and Herzegovina2 . The test consisted of 36 sentences. In relation to the length, sentences were divided into three groups: in the first group there were 9 sentences which included 3 to 5 words, in the second group, there were 14 sentences which included 6 to 8 words and in the third group there were 13 sentences which included 9 to 11 words. Testing was conducted so that the examiner was pronouncing one sentence after which the participant repeated the same sentence. Each participant was requested to repeat exactly what he/she had heard. Speech and language pathologist has recorded all speech disfluencies in all sentences. The results showed that the sentences containing 9 to 11 words had most effects on the overall dynamics of speech disfluencies in children who stutter. The results suggest that during the process of assessment and diagnosis of children who stutter, it should be required to assess the child's ability to use complex linguistic statements and to assess the frequency of disfluencies in relation to the complexity of the sentences. Precision diagnostics would provide guidelines for the treatment of stuttering in terms of implementation of approaches and strategies which include language treatment and gradually increasing the length and complexity of statements of children who stutter during speech.

: 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.

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.
