In this work, through the research which was organized in one high school in Bosnia and Herzegovina, the influence of exercises on the final result in the elearning environment at the final test done by students will be shown. The research was conducted in the subject of informatics in years I, II and III. The questions included multiple choice, open-end and matching questions. The aim was to see how much influence these online exercises had on the final outcome. This was demonstrated through the final informatics tests taken by students in a classical way in the classroom, after the completion of teaching of the subject matter planned according to high school rules. In the research, care was taken to provide the conditions necessary to conduct the experiment with regard to technical requirements allowing students access to the blended system of teaching. Recent experience has shown that the young like to use IT and communication devices. In order to secure the necessary conditions, a survey was conducted among the students about meeting the technical preconditions of access to online testing and about students' knowledge of work with the Claroline LMS platform. The aim was to increase motivation of high school students with regard to the use of online materials, because in high schools of Bosnia and Herzegovina almost nothing is being undertaken concerning the implementation of new information and communication technology.

This text represents summary version of the final report on research conducted as part of the project of „Monitoring candidates‟ respect of their commitment to ethical behavior during the election campaign.' (or 'Monitoring of pre-election campaign') Research was conducted during period of June 1, 2010 to November 1, 2010 on the entire territory of Bosnia and Herzegovina (B&H). The aims of research titled „Monitoring candidates‟ respect of their commitment to ethical behavior during the election campaign‟ were to conduct monitoring of pre-election rhetoric of 1. key political subjects, 2. most influential media and 3. inside institutions of power and entire public discourse for the first time in B&H.

Here we examine the incidence and frequency of wildlife-vehicle collisions (daily and yearly dynamics) in Karlovac county. In the period from 2005 to 2008, 743 wildlife- vehicle collisions were recorded. 83,58 % of road killed wild animals were roe deer (Capreolus capreolus), 6,46 % wild boar (Sus scrofa) while the recorded proportion of other species was low. The highest risk of collision was in April and May, although the risk was high in other seasons as well, especially during autumn. Majority of daily collisions occured in the morning (5 a.m.-8 a.m.) and in the evening (6 p.m.-10 p.m.). The results of this research will be used as basis for implementation of mitigation strategy.

The blasting process remains a potential source of numerous environmental and safety accidents. The majority of these accidents were contributed to the flyrock and lack of blast area security. A field-scale investigation related to flyrock accident was conducted in an andesite quarry where rocks up to 50 cm in diameter were propelled almost 300 m from the center of blasting field causing extensive damages to the surrounding objects. The study revealed that accident occurred due to the existence of andesite alteration in one section of the blast field. The existence of this alteration caused a sliding of rock masses along the subsistent joint planes and thereby reduced burden for the second row of blastholes. Alterations involved small area of andesite masses that were not detected by previous geological exploration or visually observed prior to initiation of blastholes. The result of this filed investigation should have a positive impact on hazard awareness, prevention and safe blasting practices in mining and construction industries.

Stokes-Dirac structures are infinite-dimensional Dirac structures defined in terms of differential forms on a smooth manifold with boundary. These Dirac structures lay down a geometric framework for the formulation of Hamiltonian systems with a nonzero boundary energy flow. Simplicial triangulation of the underlaying manifold leads to the so-called simplicial Dirac structures, discrete analogues of Stokes-Dirac structures, and thus provides a natural framework for deriving finite-dimensional port-Hamiltonian systems that emulate their infinite-dimensional counterparts. The port-Hamiltonian systems defined with respect to Stokes-Dirac and simplicial Dirac structures exhibit gauge and a discrete gauge symmetry, respectively. In this paper, employing Poisson reduction we offer a unified technique for the symmetry reduction of a generalized canonical infinite-dimensional Dirac structure to the Poisson structure associated with Stokes-Dirac structures and of a fine-dimensional Dirac structure to simplicial Dirac structures. We demonstrate this Poisson scheme on a physical example of the vibrating string.
