Like any crisis in the human world, the migrant crisis can be approached without more comprehensive interpretations and deeper understanding. Nevertheless, recognizing intuitions at the first observations of European and Balkan "migrant events" is prudent, and beyond prejudice and pre-understanding, to search for the causes of the crisis. The ongoing migrant crisis has highlighted the need to create and implement a multidisciplinary model of understanding the 21st-century conflict. Models used so far halved from mega authorial theories and political doctrines, such as various pro-globalization or anti-globalization approaches, transitional neoliberal formulas, the pattern of "new world order," or "clash of civilizations," clashes of religions and cultures, world system, post-imperialism, various postmodern theories, doctrines of so-called soft and hard power, they have proven to be incompliant to events and therefore insufficient for a complete understanding of the contradictions and contradictions of the modern world. Historically, the current migrant crisis has regained the importance of questioning the spatial dimensions of the European populist configuration. The current and previous migrant problems have reminded classical and contemporary geopolitical theories of the original understanding of this approach to social and political phenomena, long overdue by Rudolf Kjellen. In one of the earliest divisions of geopolitics, a deserved place was found by demo politics. The focused demo-political reflection gains importance in situations of growing demographic problems. While geopolitics primarily encompasses processes of changes in space and area, demo politics touch on politically conditioned processes in the population. In seemingly chaotic demo politics, it reaffirmed the importance of a critical geopolitical interpretation of migrant processes. Even among the pro-non Eurocrats, for various ideological reasons, extremely inclined to specific geopolitical ideas and arrangements, it strengthened the sense of continental spatiality, accompanied by the knowledge that geopolitics "after all" has returned to European and world relations. In addition to many crises that have befallen Europe, the return of geopolitics has been contributed by the disruption sustained by the migrant wave. The current migrant crisis is a causal-consequential crisis, which means that as an already emerging disorder, it causes many other diseases that would not be without its effect. Still, it is also caused by factors that have previously shaped it and may not be known enough until this moment. The driving and emergence of the migrant crisis have occurred in the past; its modern development encompasses the present, and, likely, the migrant crisis will be faced by Europe in the future. Hence, it is necessary to bear in mind the concrete historical dimension of the problem, which also contains specific chrono-political components. When something is not understood as before at one time, the development usually enables that if it is to be understood in the consequential time.

Tourism is very important for the development of the country. In order to develop, every country must invest in tourism and use its resources to attract tourists. This research took into account how natural and cultural resources influence the improvement of tourism performance. On that occasion, it was observed what influence the rate of economic growth has on the relationship between natural and cultural resources and the performance of tourism. Therefore, regression analysis was used with the mediator gross social product, which represents economic growth. The results showed that three out of four tourism performances are influenced by natural and cultural resources when changing the rate of economic growth. In this way, it has been proven that natural and cultural resources influence the performance of tourism. That is why tourism must be based on the natural and cultural resources available to the country. It is necessary to invest in infrastructure, especially in road infrastructure, in order to make these resources more accessible to tourists.

Unlike most military high explosives, which are characterized by an almost plane detonation front, ammonium nitratebased commercial explosives, such as ANFO (ammonium nitrate/fuel oil mixture) and emulsion explosives, are characterized by a curved detonation front. The curvature is directly related to the rate of radial expansion of detonation products in the detonation driving zone and the rate of chemical reactions, and it is one of the characteristics of nonideal explosives. The detonation theories used to model the nonideal behaviour of explosives require both reaction rate and rate of radial expansion to be known/specified as input data. Unfortunately, neither can be measured and what is mostly used is a link between these rates and parameters which can be more easily measured. In this paper, the Wood-Kirkwood approach of determination of radial expansion through the radius of detonation front curvature and the electro-optical technique for experimental determination of detonation front curvature of ANFO explosives is applied. It was shown that an experimentally determined radius of detonation front curvature vs charge diameter, incorporated in the Wood-Kirkwood detonation theory, can satisfactorily reproduce experimental detonation velocity-charge diameter data for ANFO explosives, especially when the pressure-based reaction rate law is also calibrated (D=1.3 and k=0.06 1/(μs/GPaD)).

Deep eutectic solvents (DESs) are called 'designer solvents' due to various structural variations and the benefit of tailoring their physicochemical properties. For industrial applications of DESs it is crucial to know their physical and thermodynamic properties such as density, viscosity, and refractive index. These properties were measured for three lecithin (LEC)-based DESs with glycerol (G), triethanolamine (TEOA), and oleic acid (OLA) as functions of temperature. The viscosity was fitted by both Arrhenius-type and Vogel-Tamman-Fulcher equations. The density, viscosity, and refractive index of tested DESs decreased with the increase in temperature. The LEC:G DES exhibited the lowest density at all tested temperatures. This DES was selected as a cosolvent in the ethanolysis of cold-pressed black mustard (Brassica nigra L.) seed oil catalyzed by either calcined or non-calcined CaO. The reaction was carried out in a batch stirred reactor under the following conditions: the temperature of 70?C, the ethanol-to-oil molar ratio of 12:1, and the amount of DES and CaO of 20 and 10 wt.% (to oil), respectively. The presence of DES accelerated the reaction, while the separation of the final reaction mixture phases was faster.

: The aim of this paper is to address the issues dealing with politics and religion in the Middle East, focusing on secularism vs. Islamism; the aftermath of the Arab Spring, and the Shia and Sunni split, as key themes for the purpose. Via analysis of the complexity of the Middle East, the Secular-Islamist Conflict, the Arab Spring and its outcomes, the article explains how the Arab Spring hardened the traditionally fluid relationship between the politics and Islam. It argues that Islam has never actually left the political realm, as there is still political contestation about the role of Islam in public life. The paper then deals with the complexity of the Shia and Sunni relationship and the split between the two, giving the explanation for such occurrences on the three levels – doctrine, legitimacy, and power.

Tissue ischemia means insufficient blood flow to a certain area of the body. Interruption of the arterial blood supply leads to an imbalance between metabolic supply and demand and the development of tissue hypoxia. Tissue hypoxia induces metabolic changes that result in inflammation, increased production of reactive oxygen species, and cell death. If adequate blood flow is established in the ischemic tissue, there will be an increase in cellular damage, which is referred to as ischemic-reperfusion injury. Ischemia and ischemia-reperfusion injury are at the root of numerous diseases widely present in modern society, such as myocardial infarction, cerebral insult, acute kidney injury. For now, there is no way to directly affect cellular hypoxia, but the clinical treatment of hypoxic conditions is aimed at modulating global hypoxemia and increasing the amount of oxygen dissolved in the blood. Hyperbaric oxygenation (HBO) is a treatment during which the patient breathes 100% oxygen under a pressure of at least 1.4 atmospheres. Although the use of hyperbaric therapy was recorded as early as the 17th century, today this treatment is approved for a few indications.

Cadmium (Cd) is an extremely toxic metal that is widespread in nature. Due to its favorable properties, it was widely used in the industry for the production of alkaline batteries, accumulators, pigments, and colored alloys. However, it has been shown that exposure to low concentrations of cadmium leads to damage to many organs and organ systems, and the use of this metal in industry is reduced, and it is replaced by other, less harmful materials. Today, fossil fuel combustion and cigarette consumption are important sources of cadmium exposure. Numerous studies have examined the toxic effects of cadmium and they highlight the kidneys, liver, gonads as the organs that suffer the most damage. The kidneys, as the main place of cadmium storage in the body, are mostly exposed to its toxic effects. In the proximal tubular cells of the kidney, exposure to cadmium disrupts transport processes. Although ionized cadmium (Cd 2+) is thought to be largely responsible for the damage that occurs, the role of the cadmium and metallothionein complex (Cd-MT) cannot be ignored. Peritubular exposure to ionized cadmium indirectly leads to a decrease in the activity of the Na + /L-alanine cotransporter and a decrease in the rate of slow repolarization of the luminal membrane, while the Cd-MT complex leads to both direct and indirect inhibition of this transporter. Also, the Cd-MT complex inhibits Na + /Glucosa cotransporter activity. Exposure to cadmium also leads to a decrease in the endocytic uptake of low molecular weight proteins, which is accompanied by microalbuminuria.
