Abstract Pure and Cr-doped hematite (α-(Fe1-xCrx)2O3, x = 0, 0.026, 0.039, 0.085 or 0.135) nanorods were prepared by a simple co-precipitation and calcination method. Influence of different levels of Cr doping on the change of properties of long and thin pure hematite nanorods was investigated. Cr3+-for-Fe3+ substitution in the crystal structure of hematite was proved by measuring a gradual contraction of the unit cell and a gradual decrease of the hyperfine magnetic field by increasing the Cr molar fraction. Cr doping induced an increase in the width and thickness of hematite nanorods, as well as a decrease in the overall surface area. Low temperature 57Fe Mossbauer spectroscopy showed that the Morin transition in hematite was suppressed by Cr doping to temperatures below 80 K. Magnetic measurements confirmed the suppression of the Morin transition in Cr-doped hematite down to 5 K. Infrared spectra of Cr-doped hematite samples showed shifts of IR bands by Cr3+-for-Fe3+ substitution. Optical properties of α-Fe2O3 nanorods changed significantly by Cr doping – the absorption edge was shifted to higher wavelengths, accompanied by a greater absorption in the visible range and narrowed direct and indirect optical band gaps. The improved visible light photocatalytic activity of hematite nanorods in the heterogeneous photo-Fenton process by moderate Cr doping was measured, which can be attributed to the modifications in electronic structure and optical properties.

Physical movement - an exercise, which springs from our being and returns to it as a gracious food, with its agon, that desire to compete with others but also with itself, helps a human being to become and remain a personality. This statement is confirmed by people who marked the 19th and 20th century. By their example and work, they not only testified the benefits of physical exercise, but also encouraged the formation of theoanthropocentrism, one of the theories of physical culture, at the end of the 20th century. Metropolitan Hadzi Sava Kosanovic, Bishop Rade, Bishop Nikolaj of Zica, Vasa Pelagic, Cedomir Milic, are just some of those who testified and encouraged others by their example not to forget about physical exercise and their body. Because in the union of body and soul sanctified by the Holy Spirit, that trinity survives only if all and each of them is taken care of, in specific. With examples of their attitude towards physical exercise and competition, which they only pointed out or others wrote about, we will lighten up a significant part of the history of physical culture.

Physical Culture, as a part of general culture, can be defined as a human activity, which, through its knowledge ABOUT and FOR physical exercise within its areas (physical education, sports and physical recreation), allows the transformation of personality from real to possible. Physical Education, as one of the areas of Physical Culture, is therefore a very important educational link. It is particularly important in anera characterized by fast technological advances and technicalism that is rapidly introducing people to virtual reality. Hence, we emphasize that Physical Education, with its knowledge ABOUT and FOR physical exercise, builds the basis for a healthy, active and long life in young people. This is possible due to the fact that Physical Education, based on the Theory of Theoanthropocentrism, sees physical exercise as a beneficial body activity necessary for man and stems from the relationship to a man as a person, not an individual. The increasingly present virtual reality is in complete harmony with the sedentary culture, increasingly dominant not only in Western civilization. This undoubtedly leads to "active" hypokinesia, the root of many disturbing changes and health problems. Anthropological research conducted in Serbia and AP Vojvodina have confirmed that the number of people who regularly engage in physical exercise is decreasing. That is why we point out the importance of Physical Education, which, with its knowledge of how and why to exercise, builds the awareness of the necessity for physical exercise, as well as of the possibility of seeing every physical activity as physical exercise.

Distant abscesses are uncommon during the episode of acute pancreatitis (AP). However, these are possible sequalae of necrotizing pancreatitis and should be treated appropriately to prevent serious septic complications. We demonstrate a case of a 56-year-old male patient who presented with severe necrotizing pancreatitis and distant retroperitoneal abscess that reached femoral region and was detected on diagnostic imaging scans. Combination of surgical and supportive therapy was employed, and the patient recovered well with no permanent consequences. Our article highlights the importance of quick and accurate diagnosis and timely intervention in this rare type of pancreatitis complication.

According to both theoretical and empirical research results, this paper has the aim to determine, the extent to which the current accounting regulatory framework (IFRS 3 and IAS 36) offers an adequate basis for correct valuation of goodwill. We have researched all the available critical reviews of the accounting treatment of goodwill and the quality of applying accounting regulations onto expression of the goodwill position in BH companies’ practices. The empirical research was conducted on all the companies in the Federation of Bosnia and Herzegovina (FBiH), which recorded goodwill in their balance sheets in the period from 2013 to 2018. The research results have shown a high level of subjectivity in the process of determining the value of goodwill, and great discrepancies in adhering to the accounting regulations in the part of additional valuation and expression of goodwill value in financial reports. This resulted in the fact that the share of companies in FBiH which express decreased values of goodwill is far greater than the share of companies in the European union (EU). The main contribution of this paper is the fact that this is the first comprehensive research on evaluation of goodwill in FBiH companies in comparison to the situation in the EU. Also, it confirms the Agency Theory and shows great subjectivity in evaluation which results in an unjustified expression of a higher operative success in financial reports.
