excellent resistance to hard water, and is suitable with various kinds of surfactants. Mixing anionic and cationic surfactants is not recommended. The aim of this paper is to show the influence of individual surfactants and their mixtures on the final properties of liquid soaps as well as the antimicrobial activity of surfactants and the advantages of biosurfactants. The highest antimicrobial activity is reported for surfactants containing 10-14 carbon atoms in their chain. The toxicity of cationic surfactants is the highest, then follow anionic and the last one is nonionic. Biosurfactants show the same functionality as the chemical synthetized surfactants, but biosurfactants are more environmentally friendly, with lower toxicity and biodegradable ability.

Galvanic coatings are applied so that the surface of the base material obtains appropriate properties, corrosion resistance, durability, aesthetic appearance, and long-term application in the appropriate industry. In this paper, the aim was to protect steel fuel filters with alkaline and acid zinc coatings of different thicknesses. The coating of zinc, which is applied from the alkaline electrolyte, provides good corrosion protection with excellent coating flexibility. The thickness of the coating by the X-ray fluorescence method was tested, followed by coating tests, corrosion resistance, and electrochemical tests. The results of adhesion showed a high quality coating, as no corrosion occurred during the test. The corrosion resistance tested by the salt chamber method speaks of the appearance of white and red corrosion. On alkaline electrolyte coatings, white corrosion occurred after 168 hours of exposure to the salt test, while on white zinc samples there was a white corrosion after 240 hours of exposure. Tafel polarization diagrams have been determined: corrosion potentials, current intensities, anode and cathode Tafel coefficients and calculated corrosion rates. The active and passive corrosion zone is determined by the cyclic voltammetry.

In this paper, within the framework of morphostructural features, relationship between relief and geological structure in the river basin of Solina (north-eastern Bosnia and Herzegovina) is analyzed. Main goal of this study is to investigate causal relationship between complex geological characteristics of the terrain and genesis, morphological evolution and differentiation of three relief units in the river basin of Solina. Relief of river basin of Solina is predominantly non-conformal, tectonically predisposed; its structure is dominated by Cretaceous - Paleogene clastites. In this paper are applied modern geomorphological-geological methods, field work, analysis of topographic and geological maps, as well as satellite images of the studied area. Presentation of data has been realized in the Geographic Information System, and the geospatial data were geo-visualized on two thematic maps.

The intention of this work is to examine the profile of Mann’s protagonist as one of the typical literary representations of artist, from the aspect of Nietzsche’s concept of Appollonian and Dionysian taking closer look at complex relation of motives of love, beauty and death within the life that is inseparable from an artistic existence. Gustav von Aschenbach, a writer of firm will, rationality and conscious principles, on his final journey to Venice, transcends borders and does something like an ancient hubris, yielding to Dionysian intoxication and seduction. This kind of duality within his character is the starting point for our interpretation. The analysis intents to show how the encounter with a Polish boy affects Aschenbach’s life and art, how the writer reacts in contact with beauty, and how this causes the release of his true Dionysian nature. The Venetian chronotope and unusual carnival atmosphere also influence changes in Ashenbach’s behavior, so that in a different environment, which activates the Dionysian element of his being, his character is necessarily transformed. Aschenbach’s art, as ambivalent as his life, exists between the Apollinian and Dionysian elements that constantly condition and supplement each other. Keywords: Thomas Mann, Nietzsche, Apollinian, Dionysian, art, beauty, death, Venice.

The main objective of this research is to measure the efficiency of commercial banks operating in the Federation of Bosnia and Herzegovina in the period 2016-2017. An analysis is conducted of over 12 banks that had positive overall profit lost at the end of 2016 and 2017 years published by the Banking Agency of Federation of Bosnia and Herzegovina. Data Envelopment Analysis (DEA) method with two input and three output parameters is used for efficiency measurement. Each bank’s efficiency is presented for the 2016 and 2017 years. For an observed period, large banks showed more efficiency than small banks. Based on the results shown in this research and features used in this model there is a significant difference in the relative efficiency of the top two banks and the rest of the 10 banks.

Vertebral artery fenestration is a rare vascular anomaly. It most commonly occurs in extracranial segments of the vertebral artery. This congenital anomaly can occur during the various stages of embryonic development of the vertebral artery. This usually does not have clinical significance, but the possibility of associated anomalies such as saccular aneurysms and arteriovenous malformations should be noted. Awareness of vascular anomalies is key to avoiding iatrogenic injury during endovascular diagnostic and therapeutic interventions. Here, we present incidental findings of vertebral artery fenestration in a 46-year-old woman evidenced by CT angiography of the neck's blood vessells after I .V. contrast medium applications.

We model shallow-water waves using a one-dimensional Korteweg–de Vries equation with the wave generation parameterized by random wave amplitudes for a predefined sea state. These wave amplitudes define the high-dimensional stochastic input vector for which we estimate the short-term wave crest exceedance probability at a reference point. For this high-dimensional and complex problem, most reliability methods fail, while Monte Carlo methods become impractical due to the slow convergence rate. Therefore, first within offshore applications, we employ the dimensionality reduction method called Active-Subspace Analysis. This method identifies a low-dimensional subspace of the input space that is most significant to the input–output variability. We exploit this to efficiently train a Gaussian process (i.e., a kriging model) that models the maximum 10-min crest elevation at the reference point, and to thereby efficiently estimate the short-term wave crest exceedance probability function. The active low-dimensional subspace for the Korteweg–de Vries model also exposes the expected incident wave groups associated with extreme waves and loads. Our results show the advantages and the effectiveness of the active-subspace analysis against the Monte Carlo implementation for offshore applications.

This paper explores the dynamic relationship between economic freedom and tourism industry. In addition, the impact of economic growth is controlled in the extended model. Balanced panel data are collected for 100 countries over the period 2002-2015. The methodology includes panel data econometrics. Therefore, models are initially estimated using fixed and random effects models. Moreover, models are estimated using linear dynamic panel data estimators based on GMM framework. The results of linear static panel data estimators indicate a significant positive impact of economic freedom on tourism in both, initial and extended model. Stronger impact is reported in initial model. Dynamic panel data models confirm these results with the stronger impact reported in extended model. Given the importance of tourism industry, this paper suggests that governments should do necessary changes to foster the economic freedom since it is found to be an important factor to attract the foreign tourists.

Spondyloarthropathy is a form of arthritis that affects spine, especially sacroiliac joint leading to the severe, chronic pain and over time, can cause complete fusion of the sacroiliac (SI) joint. The present report describes a case of spondyloarthropathy in a captive female brown bear ( Ursus arctos ) from Sarajevo zoo, Bosnia and Herzegovina. Morphological inspection and radiograph of the macerated sacral and coxal bone specimen was performed. Both examinations showed complete bilateral symmetrical fusion of the sacral and coxal bone with syndesmophyte formation. Animals residing in zoos are kept under specific conditions which lead to inactivity and possible mobility problems caused by some sort of spondyloarthropathy.

The issue of management process in all organizations with a pronounced hierarchical structure is extremely complex and equally abstract to both the participants themselves and all those who deal with the study of this topic. The management process involves decision-making based on appropriate economic analysis, experience, practice, micro and macro environment, and the ability of an individual manager to create a symbiosis based on all the knowledge that will ultimately lead to making an appropriate business decision. The aim of this paper is to build a presentation of the model, which in this case will improve the economic community and enrich the everyday work of companies. This will allow the ownership and management structures of a large number of inadequately structured and internally non-institutionalized companies to become active and passive managers of all business relations within the companies in which they operate, instead of active or passive observers. In this paper, a management model will be presented based on the data researched within five variables: quality of human resources, economic incentives, development perspectives, managerial capabilities of subordinates and business satisfaction. One of the aims of this paper is precisely to explore how these variables influence the business satisfaction of Croatian companies. The research was conducted in the territory of the Republic of Croatia, in all regions, on a representative sample, while representatives of the companies were surveyed. The answers obtained were analysed descriptively, through the regression model. It has been proven that the greatest influence on pleasure in business is influenced by managerial capacities, where beta coefficients is 0.367. Slightly less impact on the pleasure of doing business has the development of enterprises and incentives from the budget, while the smallest impact on the pleasure of doing business has human potential. The obtained beta COTA is statistically significant because the p – value
