After the ruling of the European Court of Human Rights in the case of ‘Sejdic&Finci vs. Bosnia and Herzegovina’, it is evident that election system of Bosnia and Herzegovina is discriminatory and that it is necessary to conduct systematic reform of this area, in order to satisfy the basic principles of contemporary democratic election systems, and in order to make election system, together with the B&H Constitution, compatible with the European Convention On Protection Of Human Rights And Fundamental Freedoms.

This paper presents the analysis of the infl uence of conventional hot (CH) and high frequency (HF) gluing on relevant physical and mechanical properties of Laminated Veneer Lumber (LVL) made from beech peeled veneer with the thickness of 2.1 mm. Student’s T-test was applied to determine the signifi cance of differences between mean values of results obtained for the two different treatments. A signifi cant difference has been determined for the thickness loss, density, moisture and bending strength, while no statistically signifi cant difference has been established for the modulus of elasticity and shear strength of gluing between the means of the tested samples.

Results of a large amount of research show that adolescents are not sufficiently informed when it comes to reproductive health. The aim of this paper was to investigate how well informed adolescents in the Republic of Srpska were about reproductive health and what their attitudes towards it were. The research was designed as a cross-sectional study which included 683 adolescents - 562 12 years old and 121 15-year-old adolescents from eight regions in the Republic of Srpska. The data on pupils’ knowledge of and attitudes towards reproductive health was collected through a questionnaire – survey which pupils completed individually in the presence of trained interviewers, who were available in case of difficulties with understanding questions. Methods of Descriptive Statistics were used to describe the sample in question, and the χ 2 test was used to determine statistical significance of differences in age. By analyzing the awareness of the 12-year-olds and 15-year-olds, it was found that there was a statistically significant difference in the distribution of answers to the following questions: What is puberty? (χ 2 =8.050; p<0.01), What is menstruation? (χ 2 =11.935; p<0.01), What is conception? (χ 2 =22.974; p<0.01), What is abortion? (χ 2 =8.851; p<0.01). According to this research, every fourth 12-year-old and eighth 15year-old received information on reproductive health from their parents. Most young people (54.9%) would ask their parents for advice on solving sexual life issues, while only 2.8% would ask their teacher. Every fourth adolescent would ask their peers for advice on solving sexual life issues. Out of all adolescents that took this survey, 79.1% think that it would be useful to have Sexual Education as a school subject. Results of this research indicated the need for more intense implementation of education programmes in the field of reproductive health among adolescents in the Republic of Srpska.

Oba su određena na temelju 120 ortopantomograma. Rezultati: Srednja vrijednost indeksa MI bila je najviša kod pacijenata s potpunom denticijom, niža kod onih s djelomičnom ozubljenošću (Kennedyjeva klasa I), a najniža kod potpuno bezubih. Post-hoc testovi pokazali su statistički značajnu razliku za indeks MI na objema stranama između Kennedyjeve klase I i potpuno ozubljenih pacijenata (p≤0 ,001) te između potpuno ozubljenih i bezubih pacijenata (p≤0,001), ali ne i između Kennedyjeve klase I i potpuno bezubih pacijenata (p=0,470). Potpuno ozubljeni pacijenti ujedno su bili i najmlađa skupina pacijenata. Pacijentice su imale mnogo niže vrijednosti indeksa od pacijenata. Chi-square test pokazao je statistički značajnu razliku za indeks MCI između skupina pacijenata različitog dentalnog statusa, ali ne i između onih grupiranih prema spolu. Zaključak: Dentalni status i godine mogu utjecati na MI i MCI.

The selection of most appropriate design and technological solutions to produce certain mould should capture technical performance, economical issues and also environmental impacts occurred during the mould life cycle. In the paper an approach is presented to support the selection of alternative mould design solutions in the early design stage. It includes the use of Life Cycle Assessment methodology, Life Cycle Cost methodology and is supported by numerical simulations. Approach is applied to a case study where three mould designs for production of the same plastic product were compared. At the end general conclusion regarding the resource efficient injection moulding processes are presented.

Solos sao as principais fontes de mercurio (Hg) para o sistema fluvial amazonico, especialmente em areas alagaveis fluviais, principais sitios de metilacao desse metal. O objetivo deste trabalho foi investigar a influencia da Fm. Alter do Chao na dinâmica de Hg tot e a variacao e proporcao deste metal em microbacias, drenado por esta formacao geologica proxima a Santarem-PA. Os procedimentos metodologicos incluiram: aquisicao, processamento, analise de imagens de radar, imagens opticas e dados interferometricos SRTM para confeccao de mapas, georreferenciamento dos pontos de coleta e identificacao da area da pesquisa; classificacao, quantificacao de material em suspensao e sedimentos das areas identificadas na Fm. Alter do Chao para determinar o mercurio total encontrado nas amostras e nivel de contaminacao por Hg tot na foz do rio Tapajos
