A perfect dielectric model was incorporated into the OpenFOAM? software and used for investigation and, possibly, improvements of electrohydrodynamic calculations. Two different sets of numerical simulations were analyzed, in which two different fluids were present. The first set was one-dimensional, while in the second, a drop of one fluid was surrounded by the other fluid. It is shown that oscillations and possible artificial generation of a curl of the electric field strength can be observed at applying certain expressions or calculation strategies, which can be thus abandoned. Usage of dynamic meshes, at least those present in the used software, and of limiters for the gradient of the electric field strength can lead to large numerical errors. It is also shown that usage of certain cell face values could improve the results. An electric Courant number was derived by dimensional analysis, and it could be suggested for future calculations. Conclusions made in this paper are expected to be transferable to other more complicated models.

: In the regional historiography of World War II in Yugoslavia, written in both the socialist and post-socialist periods, Wehrmacht generals are mentioned almost exclusively in the context of war crimes. Almost nothing is known about their origin, personal life

The promptness of providing services to patients directly affects the success of healthcare organizations. In this regard, the implementation of contemporary concepts in healthcare organizations is synonymous with success. Subject of research: The subject being researched in this paper is the possibility of applying the SIPOC method to the clinical process in obstetrics. A more precise application of the abovementioned method would mean a prompter implementation of activities within the clinical process (pregestational counseling, antenatal care of expectant mothers, deliveries, supervision of women during puerperium). Through the activities of the abovementioned clinical process, an effort is made to meet the health needs of expectant and new mothers. The application of the SIPOC method is not sufficiently present in clinical processes, especially the clinical process in obstetrics, and therefore this paper opens a new research area. Aim: The aim of this paper is to indicate the relevance of the SIPOC method as one of the tools within the Lean methodology, which can be used to improve the clinical process in obstetrics. Materials and methods: The following materials and methods were applied in this study: the method of analysis, the inductive - deductive method, the method of synthesis, the method of description, the method of proof. Case analysis was also used in the application of the SIPOC matrix at a gynecology and obstetrics outpatient clinic. Results: The results of the research showed that there was a positive impact on improving the efficiency of the provision of health services, through the implementation of modern methods. The SIPOC method affected the improvement of the efficiency of the clinical process in obstetrics. The review of the literature and the obtained results revealed that there is no formalized concept with instructions on the implementation of clinical process improvement methods.

Protests among citizens of Bosnia and Herzegovina are becoming more frequent. Most often, their aim is to decry the dysfunctionality and opacity of the government, which are the result of the ethno-political structure created by the Dayton Agreement, but also a trend towards democratic regression and autocracy. A number of authors have tackled the ?JMBG? protests of 2013 and the Plenums that emerged from the February 2014 protests, from their particular disciplines. The focus of this paper is the social movement ?Justice for Dzenan,? organized by the Memic family upon the tragic death of Dzenan Memic in Sarajevo in February 2016. An in-depth study was conducted with key actors of the movement, as well as those who follow or in some way support the protests. Particular emphasis in the research was paid to the pragmatic symbiosis of the social movement and one political party. We argue that it is possible to identify a pragmatic symbiosis as a novel form (democratic innovation) of socio-political cooperation that can impede rising autocratization. Through the quest for accountability, social movements are introducing new strategic practices of mobilization and a novel type of alliance-building with external factors (new political parties as well as other social movements). The goal of the paper is to explore how the social movement ?Justice for Dzenan? interacts with political parties and approach the political sphere in BiH. Also, the idea is to examine the possibilities and functionality of this kind of cooperation with the framework of contentious politics.

Plant extracts are widely used as biofungicides and medical bioproducts because of their eco-friendly nature and cost effectiveness. The present investigation focuses on the activity of a solvent based on industrial hemp extracts against two phytopathogenic fungi and five human pathogenic bacteria. The present study suggests the potential of the industrial hemp extracts for the development of novel broad spectrum herbal formulations used in plant protection and medicine.

Using natural and modified Ca-bentonite as an adsorbent to observe a satisfactory trend in the removal of heavy metal ions As(V) and Hg(II) from simulated wastewaters. In this original scientific paper, Ca-bentonite was modified in two ways, thermally activated at a temperature of 300 °C for 3 hours and acid activated with HCl and H2SO4, molar concentrations 0,4 mol/L. Ca-bentonite used in this original scientific work was used from the Shipovo mine (Šipovo mine), Bosnia and Herzegovina and proved to be an excellent bioadsorbent for the removal of present ions from simulated wastewaters. Also this is eco-friendly adsorbent and low costed compared to other expensive adsorbents. Due to its chemical composition in which two oxides predominate, namely SiO2 (48.28 mass %) and Al2O3 (23.04 mass%), it can be concluded that Ca-bentonite from the Shipovo mine (Šipovo mine), Bosnia and Herzegovina belongs to the group of refractory materials. The highest removal efficiency of As(V) ions expressed in % was 75.11 at the initial concentration of 1.5 mg/L and was recorded using HCl acid-activated Ca-bentonite. The efficiency of Hg(II) ion removal was the highest using thermally activated Ca-bentonite and this value was 99.66% at an initial concentration of 1 mg/L.
