Introduction: Inflammation plays an important role in atherosclerosis which is the primary cause of acute coronary syndrome (ACS) that encompasses acute myocardial infarction (AMI) and unstable angina (UA). Objective: To investigate and characterize white blood cells (WBC) count, differential blood count in peripheral blood and neutrophil to lymphocyte ratio (NLR) in patients by the type of ACS. Patients and methods: The cross-sectional study included 100 patients with ACS (50 males, 50 females), aged 41 to 91 years, classified into two groups: AMI group (n=50) and UA group (n=50). Patients were hospitalized at the Clinic for Heart Diseases, University Clinical Center of Sarajevo. From patients’ medical histories the following data were obtained: WBC, neutrophil, eosinophil and basophil granulocytes count, monocyte and lymphocyte count, levels of high sensitive troponin I (hsTnI), creatine kinase MB (CK-MB) and C-reactive protein (CRP). The results were analyzed using software package SPSS, version 19.0. Results: Average WBC count, neutrophil granulocytes, and monocytes were significantly higher in AMI group than in UA group (p = 0.001, p < 0.0005, p = 0.03, respectively). Eosinophil count was significantly lower in patients with AMI (p = 0.022). NLR was significantly higher in AMI group in relation to patients with UA (p = 0.001). Significantly higher values of hsTnI and CK-MB were established in patients with AMI. NLR correlated significantly positive with the values of hsTnI, CK-MB, CRP, WBC and neutrophil count, and significantly negative with lymphocyte count. Conclusion: Average values of NLR were significantly higher in patients with AMI in relation to patients with UA, indicating the importance of this inflammatory marker in discrimination of clinical forms of ACS. A positive correlation was established between NLR and markers of myocardial necrosis, and between NLR and CRP, indicating the importance of NLR in the assessment of the extent of the myocardial lesion and in inflammation intensity assessment in ACS.

The aim of research was to analysis development and age structure of male and female participants at the Olympic Games (OG) and World Championships (WC) from 2003 until 2016. The total number of analyzed WC participants in men's artistic gymnastics (MAG) was 2678 and the women's artistic gymnastics (WAG) was 1981; while at the OG in MAG 391 and in WAG 389. In the last 15 years, there has been identified linear and second-order polynomial-regression increase in the age structure of participants in MAG and WAG in the largest world competitions. In analyzed period of time, MAG and WAG age of gymnasts increased. The male gymnasts from 2003 to 2016 are on average older for 2.3 years and female gymnasts for 3.3 years. In the upcoming period, we do expect (with apparatus specialization) that age will rise.

In this paper, the microstructure of Cu82.3Al8.3Mn9.4 (in wt. %) shape memory alloy after hot and cold rolling was investigated. The Cu82.3Al8.3Mn9.4 alloy was produced by a vertical continuous casting method in the form a cylinder rod of 8 mm in diameter. After the casting, hot and cold rolling was performed. By hot rolling a strip with a thickness of 1.75 mm was obtained, while by cold rolling a strip with a thickness of 1.02 mm was produced. After the rolling process, heat treatment was performed. Heat treatment was carried out by solution annealing at 900 °C held for 30 minutes and water quenched immediately after heating. The microstructure characterization of the investigated alloy was carried out by optical microscopy (OM), scanning electron microscopy (SEM) equipped with a device for energy dispersive spectroscopy (EDS). Phase transformation temperatures and fusion enthalpies were determined by differential scanning calorimetry (DSC) method. The homogenous martensite microstructure was confirmed by OM and SEM micrographs after casting. During rolling the two-phase microstructure occurred. Results of DSC analysis showed martensite start (M s ), martensite finish (M f ), austenite start (A s ) and austenite finish (A f ) temperatures.

When researchers formulate search queries to find relevant content on the Web, those queries typically consist of keywords that can only be matched in the content or its metadata. The Web of Data extends this functionality by bringing structure and giving well-defined meaning to the content and it enables humans and machines to work together using controlled vocabularies. Due the high degree of mismatches between the structure of the content and the vocabularies in different sources, searching over multiple heterogeneous repositories of structured data is considered challenging. Therefore, the authors present a semantic search engine for researchers facilitating search in research related Linked Data. To facilitate high-precision interactive search, they annotated and interlinked structured research data with ontologies from various repositories in an effective semantic model. Furthermore, the authors' system is adaptive as researchers can synchronize using new social media accounts and efficiently explore new datasets.

Drought in Bosnia and Herzegovina (B&H) is mostly analyzed using water deficit obtained from agro-hydrological balance; a ratio between precipitation or actual evapotranspiration (AET) to potential evapotranspiration (PET); and more recently using Standardized Precipitation Index (SPI). The main objective of this research is to use the relatively new multiscalar drought index, Standardized Precipitation Evapotranspiration Index (SPEI) to analyze severity, magnitude, and duration of drought periods in B&H. SPEI is based on precipitation and evapotranspiration data and it has the advantage of combing multiscalar character with the capacity to include the effects of variability in atmospheric water demand on draught assessment. Evapotranspiration is calculated with Penman-Monteith method, the standard international procedure for computing reference or potential evapotranspiration (ET0). In order to assess all four types of drought, SPEI is calculated for shorter (1, 3 and 6 months) and longer (12 and 24 months) time scales. Weather stations with long-term continuous climate data records were selected 13 stations across B&H in total, from which the climate data for 50-year period (1961 – 2010) were collected. A crucial advantage of SPEI over other drought indices previously used in B&H and its use of potential evapotranspiration and multiscalar characteristics, enabling identification of different drought types. By using Standardized Precipitation Evapotranspiration Index (SPEI) it was found that severity, magnitude and duration of drought periods in B&H vary depending on the location and time scale for which drought was calculated. Presence of more severe long lasting droughts in period after 1986 was found for all 13 analyzed locations across B&H.

This paper presents different possibilities of using mobile robots in education. Through the application of mobile mechatronic robotic system "Robotino" this paper shows the possibilities of developing interactive lectures and exercises in order to raise the quality of education and to provide new competencies for students. Application of robot as a real system supports strengthening specific areas of knowledge and skills that the students develop through design, creation, assembly and operating with the robot. This way of learning contains a very important element and that is "Playful learning" or learning through play. Along with technical competences, combining this method with teamwork improves also social skills and motivation for learning. This paper will present application of the robot in education on examples of modelling and designing of mechatronic systems, simulating and parameters monitoring of mechatronic systems, and collecting, processing and application of data from sensors in mechatronic systems.

We are happy to present this Special Issue on Education in Human-Robot Interaction (HRI) to the community. As HRI has matured as a field, it is also becoming an increasingly popular educational topic and resource at all levels of instruction, from elementary through graduate programs. While several excellent review articles for the field exist, there is no textbook or recognized curriculum in HRI. The interdisciplinary nature of the field presents students and instructors with opportunities for building on diverse perspectives from design, engineering, computer science, and the social sciences and humanities, as well as challenges in presenting and working with material from such a broad array of disciplines. The authors in this special issue discuss their experiences with and strategies for designing HRI curricula and teaching HRI to students of diverse backgrounds and skill sets. We hope this special issue will inspire many more courses, summer schools, and educational outreach activities in HRI. We also hope that it sparks more discussions about diverse approaches to and necessary standards for HRI curricula.

Introduction: The purpose of this study to investigate internal service quality (as perceived by employees) and external (customer) perceptions of quality in the context of service profit chain (SPC).Objective: The objective of the study is to evaluate the impact of internal service quality on students’ perceptions of quality and to test the significance of a direct link between internal and external service quality.Methods: We measured the perceived service quality using a SERVPERF instrument and the multilevel modeling approach with HLM 7.01.Results: The empirical findings support a link between perceptions of internal and external service quality. We show that when employees (faculty) perceive university services as being of high quality, it has a positive spill-over effect on students’ overallperceptions of the quality of university services. Perceptions of internal service quality are also positively related to students’ perceptions of reliability, responsiveness and quality assurance.Conclusions: The perceptions of internal service quality by faculty members are positively related to students’ perceptions of quality. Comparing the levels of internal and external service quality will help managers define priorities for allocating resources to improve quality.

The study was carried out in 2015 in the experimental orchard of the Agropodrinje apple introduction centre in the Gorazde area. The impact of different methods of calcium fertilizer application on fruit quality and calcium content in the ‘Idared’ fruit of an 8-year-old apple tree were studied. Fruit mineral composition and quality parameters were estimated after harvest. Calcium fertilizers used in this research were FolifertilCa, calcium-ammonium nitrate (CAN), and calcium oxide (CaO). Folifertil-Ca was applied through leaves, and CaO and CAN were applied through soil. The method of application where CAN was applied in combination with Folifertil-Ca significantly increased the accumulation of Ca in apple leaves and fruits. Also, this method of calcium fertilizer application had the greatest impact on apple fruit firmness increase. In the present study sugar content and acidity of apple fruit did not differ significantly, regardless of the application method of calcium fertilizers. The results of this study support the fact that the Ca uptake by plant roots and its transport to leaves and fruits are directly affected by a plant’s transpiration rate. This fact suggests that in apple cultivation is better if calcium fertilizers applied through soil or in combination with foliage treatment.
