There has been a number of reports of natural products contaminated with illegal adulterants that threaten consumer health because of their adverse pharmacological effects worldwide. In this study, a multi-residual ultra-performance liquid chromatography method with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) was applied for the identification of sildenafil added into a herbal honey mixture used as an immune system booster. Electrospray ionization (ESI) source was applied and operated in the positive ion mode. The mobile phase consisted of 0.1% formic acid aqueous solution/acetonitrile (70:30, v/v) using the isocratic gradient elution system at a detection wavelength of 290 nm. The compound of sildenafil added into traditional herbal mixed honey was identified according to the spectrum, chromatographic behavior, and mass spectral data were identified by comparison with the reference substance. The method is selective, sensitive and can be used to detect the sildenafil illegally added into traditional herbal medicinal preparations.

Alibabić V., Oraščanin M., Vahčić N. (2017): Geographical origin of honey from eight sub-regions of Bosnia and Herzegovina. Czech J. Food Sci., 35: 488–495. Principal component analysis (PCA) and cluster analysis (CA) were used to define the geographical origin of three types of monofloral (chestnut, linden, and acacia), two types of multifloral (meadow and mixed), and forest honey produced over two consecutive harvest seasons in the Una-Sana Canton (Bosnia and Herzegovina), which is geographically divided into eight sub-regions. Statistical analysis was applied to the measurement of physico-chemical and sensory parameters, as well as microand macronutrient (K, Na, Mg, Zn, Fe, Mn, and Al) content, along with some heavy metals (Cd, Pb, and As). Using the PCA method the characteristic parameters for all eight sub-regions were determined, while the CA grouping method was used to determine the characteristic parameters for six sub-regions. Chestnut honey is predominantly found in Cazin, chestnut and linden honey in Bosanska Krupa, chestnut and acacia honey in Bužim, acacia honey in Sanski Most, mixed honey in Velika Kladuša and forest honey in Ključ.

The effects of defatted hemp cake added to corn grits (in ratios of 0, 5 and 10% d.m.), the moisture content of the mixtures (15, 20, 25%) and the temperature in the extruder ejection zone (150, 165, 180 °C) on the physical properties of extruded products have been investigated. Statistical optimization of investigated extrusion conditions using the response surface methodology was performed. The hemp cake was completely defatted by means of a supercritical CO2 extraction. The extrusion was performed on a laboratory single screw extruder and regulated by the following parameters: temperature in the dosing and compression zone (120 and 150 °C), screw compression ratio (4:1), round die (4 mm). The change of extrusion process conditions has significantly affected the physical properties of produced snacks. The expansion ratio ranged between 1.38 and 3.11, the bulk density between 0.14 and 0.49 g/cm3, the hardness between 18.15 and 70.62 N, the fracturability between 3.65 and 10.38 mm, and the total color change between 3.25 and 24.73.

Introduction: A number of people with facial injuries after surgical treatment one knee time comes and a violation of the opposite knee. These injuries have a major impact on quality of life if they are not treated properly, but also have consequences and after surgery. The aim of this paper is to analyze the questionnaires used to assess the quality of life after mutual ruptured anterior cruciate ligament, and to make recommendations for optimal use of the same. Our goal is to establish a correlation between the results obtained from questionnaires used descriptive answers to questions descriptive questions about aspects of everyday life, aspects of physical activity as well as aspects of personal perception of the current health and satisfaction with it. Methods: We analyzed questionnaires used to evaluate the quality of life after a bilateral rupture of the anterior cruciate ligament, which are listed in the attached work. In accordance with the subject of research, in this paper were used the following scientific research methods: a method of deduction, analysis, classification, comparison, analysis methods of written documents. Results: By searching the PubMed database for the purpose of this master's thesis under the terms "unilateral rupture ACL" we came across a 2792 articles, while the term "bilateral rupture of the ACL," retrieved only 73 articles, "contralateral ACL rupture" 192 articles, "Quality of life ACL "  41 articles. The most important dates in our study are certainly "Quality of life after bilateral rupture of the anterior cruciate ligament," where we all find only two articles on this topic. Conclusion: The most commonly used questionnaires to be used in assessing the success of treatment and quality of life after a bilateral rupture of the anterior cruciate ligament are: QOL, IKDC, KOOS, HSS, ADL, SF-36, WOMAC. IKDC proved to be most suitable for patients with ACL rupture in this study.

Introduction Disability is one of the factors that can lead to social exclusion and poverty of individuals with hearing and speech impairment. This is due to the fact that individuals with disabilities are often underestimated, in terms of their work and social skills. The employment of people with disabilities represents a powerful mechanism for achieving full participation of the marginalized groups in all spheres of society. Methods The study included a total of 40 people with hearing and speech disabilities, out of which 16 individuals were employed at DES d.o.o. Sarajevo and 24 at SINKRO d.o.o. Sarajevo. A combination of three questionnaires was used for assessing daily activities and their impact on the quality of life (QoL) of the individuals with hearing and speech disabilities. Results In the total sample, there were 35% males and 65% females. Complete deafness was observed in the majority of participants (90%), while the rest had either moderate (7.5%) or mild (2.5%) hearing impairment. A higher number of participants used sign language as the means of communication, compared to manual alphabet. About 17.5% of the participants used a cochlear implant or a hearing aid. Most of the individuals lived with a spouse (70%), 20% lived with their parents, 7.5% lived independently, and 2.5% lived with a guardian. The majority of the participants who were married had a child (57.5%). The average Ferrans and Powers' Quality of Life Index (QLI) was 19.33, and the average value for total daily activities was 11.700 MET. The average value for the level of physical activity in males was M = 13716.5 and in females M = 10613.56 (p > 0.05). Conclusions Overall, we showed that daily activities have a positive effect on the QoL of working individuals with hearing and speech disabilities, i.e., the individuals who had a higher level of physical activity also had a higher QoL.

Summary The surface exploitation of mineral raw materials inevitably changes the environment, thus resulting in soil degradation. This paper presents the results of growing sudangrass (Sorghum sudanense Pers.) in the reclaimed Deposol (technosols) in the Stanari Coal Mine area. Green manuring was the cultural practice used for sudangrass growing and land reclamation. The purpose of this research is to increase the amount of organic matter in the Deposol surface layer. The research was performed within a two-year period (2009-2010) at the experimental (technosol) site of the Stanari Coal Mine, located on the inside part of the overburden deposition site, near the Raskovac pit. The research of green manuring included a two-factor experiment with four replications. Two cultivars of sudangrass (Factor A) were used with three fertilization treatments (Factor B). The soil analyses indicated a sandy and low fertile soil. The experimental plot Deposol showed favorable physical properties, whereas its chemical and biological properties proved very unfavourable. The highest yield of biomass (29.15 t ha-1), as well as the dry matter (10.30 t ha-1), was recorded in the cultivar ‘Piper Sweet’ (in 2009), which was completely treated with mineral fertilizers. The lowest yields of biomass (2.05 t ha-1) and dry matter (0.95 t ha-1) were observed in the cultivar ‘Srem’ in 2010. Statistically significant differences were found between the treatments applied, emphasizing that only certain cultivars of sudangrass and types of fertilization (encompassing reasonably high amounts of nitrogen) can significantly increase the amount of organic matter in Deposol.

A total number of 24 local Turopolje pigs (TP) reared in outdoor area with predominantly forest vegetation were monitored for 20 weeks (from July to December 2015) with the aim to determine the prevalence of swine gastrointestinal parasites after exposure to natural infection. At the beginning of the trial, pigs were dewormed with 300 μg of doramectin per kg of body weight (Dectomax®, Pfizer ; 1 ml/33 kg). Faecal egg counts (FECs) were determined after 14 and 20 weeks in individually obtained samples separately for large roundworm (Ascaris suum) and other gastrointestinal parasites (Oesophagostomum spp., Strongyloides spp. and Hyostrongylus spp.). The results of coprological examination showed that main gastrointestinal parasites in outdoor reared TP are helminth species with strongyle-type eggs and coccidian Eimeria spp. In typical hot and dry season, more than 14 weeks’ period after antiparasitic treatment is required for infection and development of sexually mature parasite stages and eggs excretion in the faeces. These results may be important in designing of integrated gastrointestinal management practices for TP in traditional outdoor production systems, and generally useful for more sustainable management of this endangered breed in future.

Abstract One of the key goals of the economic policy makers of every country is to achieve internal and external balance. An unavoidable segment of the analysis concerning the achievement of internal and external balance is certainly the influence of the exchange rate regime applied in a country. European transition countries, despite their similar initial problems and final objectives, applied different exchange rate regimes adapted to the economic circumstances and needs of the country. The paper aims to examine and demonstrate the impact of the applied exchange rate regime on the internal balance of the transition countries. The research encompasses 10 representative transition countries, in the period from 2000-2014. The results of the research, from the aspect of internal balance, confirmed the justification of the application of the floating exchange rate regime in more developed, but not in less-developed, European transition countries. The application of floating exchange rate regimes in less-developed transition countries is associated with a considerably higher average inflation rate, which may be explained by the higher import dependence of lessdeveloped countries and by the consequent transfer of depreciation to price growth.

Summary Digital transformation as integration of digital technology into business results in fundamental changes of way world does business, communicate and develops on national and international level. There is increase of high-tech public spending which is connected with increase of need for high-tech as well as importance and benefits that it brings to development of economy. This so called digital or high-tech sector is one of the strategic sectors in the leading world economies, starting from the US and the European Union. EU recognized it in strategic document “Europe 2020” which sees this sector as key factor in smart growth based on tech knowledge and innovation. Europe, especially western and northern Europe, is trying to keep its competitiveness in global tech arena with USA and fast developing countries such as China and India as well as Asian tech giants such are Japan, South Korea and Singapore. There is increase of European countries investment in digital transformation through private and public ICT sector development which usually has positive impact on economic growth as well as key indicators such are GDP, productivity and employment. This paper provides basic review of digital transformation and high-tech sector in Europe as well as comparison between EU and Western Balkan countries. Additionally, there is analysis of influence of ICT spending on GDP growth. Paper could serve as basic for further research in area of influence of tech investment on key macroeconomics indicators.

This chapter deals with the influence of the electric field on a Medium Voltage Indoor Post Insulator (MVIPI) with standard and modified external shapes . The goal of this chapter is to show the electric field behavior of the MVIPI with different external shapes and to introduce a numerical model with a favorable distribution of the electric field that relieves the dielectric from stress. The chapter describes an MVIPI with nominal voltage 20 kV AC and shows an existing MVIPI, an MVIPI with a different number of ribs, and an MVIPI with exceptional external shape. The MVIPI’s new external shape does not have the typical shape of the ribs, but a new outline, using the Lagrange polynomial, that will acquire its optimal form through the optimization process. A Differential Evolution optimization algorithm is used for the optimal design of the insulator’s external shape. The value of the Electric Field Strength (EFS) will be mini - mized within the permissible bounds during the optimization process. The important parameters during the minimization of the objective function are the value of the EFS in the interior and exterior of the insulator. EFS values are shown for every MVIPI example and are compared with the existing MVIPI. The obtained results are analyzed and discussed.

Abstract.The two reactions $\gamma p\rightarrow K^{+}\Lambda$γp→K+Λ and $\pi^{-} p\rightarrow K^{0}\Lambda$π-p→K0Λ are analyzed to determine the leading photoproduction multipoles and the pion-induced partial wave amplitudes in slices of the invariant mass. The multipoles and the partial-wave amplitudes are simultaneously fitted in a multichannel Laurent+Pietarinen model (L+P model), which determines the poles in the complex energy plane on the second Riemann sheet close to the physical axes. The results from the L+P fit are compared with the results of an energy-dependent fit based on the Bonn-Gatchina (BnGa) approach. The study confirms the existence of several poles due to nucleon resonances in the region at about 1.9 GeV with quantum numbers $J^{P} = 1/2^{+}, 3/2^{+}, 1/2^{-}, 3/2^{-}, 5/2^{-}$JP=1/2+,3/2+,1/2-,3/2-,5/2-.

Providing reliable and efficient operation of electronic devices often requires introducing of an additional protection from electric circuit parasitic components during the design stage. The paper analyzes the influence of a parasitic inductance on overvoltage at switching elements, which is an unavoidable part of the most electronic converters. The paper also describes the basic methods for avoiding this phenomenon. One example of an overvoltage protection of IGBT transistors based on TD350 control circuit is presented for a specific converter.
