The Alföld: Denomination and its Southern Boundary

The Alföld with its central position in the Carpathian Basin and eastern position in the Pannonian Plain represents the first among equal landscape or physico-geographical region of Carpathian-Pannonian area. Following the recommendation of the Hungarian Geographical Society’s Alföld Commission (from 1910) the Alföld should used as a geographic name and the previous denomination “Great Hungarian Plain” should be abandoned. Some parts / segments of the Alföld if use in the context restricted to the national boundaries, the proposed recommendation should be the form of the Alföld with the prefix which according to the country belongs the pointed segment (i.e. in case of Serbia - it should mention: Serbian segment of the Alföld). The southern boundary of the Alföld is well defined. It is same as SE part of the Pannonian Plain. The south parts of the Alföld encompass the Lower Sava Plain, the Tamnava-Kolubara plain, the lower Velika Morava Plain and the Mlava Plain

THE PANNONIAN PLAIN: DENOMINATION, DEFINITION AND SUBDIVISION

The Pannonian Plain is a landscape or physico-geographic unit. It encompass the plain lowland landscapes of the Pannonian realm. If we follow the Pannonian Plain along the Danube valley, it starts from with Vienna Basin downstream till the Iron Gate. The Pannonian Plain can be subdivided in six landscape units. The three main units are: The Vienna Basin, The Little Alföld, Alföld. The three smaller units have some kind of connections with the Alföld they are the Inner Somogy plain, the Drava Plain outside of the Alföld and the Sava Plain outside of the Alföld. The Pannonian Plain has no synonyms. the terms Pannonian Basin, Pannonain realm, Pannonian Basin System as well as the Carpathian Basin have different meanings

The Carpathian Basin: Denomination and Delineation

The Carpathian Basin introduced in the geographical literature of the year 1921. However, after few clarifications it became in official use in 1947. It has been used in the context of landscape unit or physico-geographical entity mainly by the Central European geoscientists. The Carpathian Basin bordered by the Alps, the Carpathians, the Dinaric Mountains and Šumadija Mountains. It represents the lowlands (and mountains which they encircled) as well as the slopes of mountains which faced to the lowlands. After multidisciplinary analysis (surface geology and roughness, orography, slope angles) the area of the Carpathian Basin delineated and presented. The analysis shown that the Carpathian Basin excludes the intramontane basins in the Carpathians and the Dinaric Mountains

Application of financial risk management systems in Serbian enterprises

Savremena preduzeća se u svom poslovanju neminovno sreću sa različitim vrstama rizika koji mogu dovesti do negativnih efekata u poslovanju. Usled promena u privredi mnoga preduzeća suočena su sa različitim vrstama rizika na koje menadžment ne može uticati. Period tranzicije u Srbiji, uticao je da domicilni uslovi poslovanja postanu još složeniji. Zato se nameće potreba za primenom različitih instrumenata u upravljanju finansijskim rizicima preduzeća. Cilj svakog preduzeća je da ostvari što veći profit uz što manju neizvesnost svog poslovanja. Zato poslovanje na tržištu sa povećanim poslovnim rizikom zahteva korišćenje različitih instrumenata II zaštite od finansijskih rizika. Poslovanje na savremenom tržištu zahteva nov način korišćenja postojećih, ali i razvoj novih metoda i instrumenata za upravljanje finansijskim rizicima. Osnovni cilj istraživanja u ovoj doktorskoj disertaciji jeste da se metode i instrumenti za upravljanje finansijskim rizicima koji postoje na razvijenim tržištima naučno istraže i da se nakon toga da zaključak o tome kakve su mogućnosti njihove primene na preduzeća u zemljama u tranziciji. Ovako postavljeno istraživanje ima i svoju društvenu opravdanost, u smislu stvaranja osnove za kvalitetnije donošenje poslovnih odluka u domaćim preduzećima, što može omogućiti i njihovo bolje pozicioniranje na inotržištimaIn their business activities, modern enterprises inevitably encounter various types of risks that can lead to negative effects in doing business. Owing to changes in the economy, many companies are faced with various types of risks over which the management has no influence. The period of transition in Serbia has made the conditions for business operations even more complex. For this reason, the need for the application of various instruments in managing enterprise financial risks arises. The goal of each enterprise is to make as much profit as possible with the smallest degree of uncertainty in doing business. Therefore, doing business in the market with increased business risk IV requires the use of various instruments of protection against financial risks. Doing business in the modern market requires a new way of using the existing methods, but also the development of new methods and instruments for managing financial risks. The main goal of the research in this doctoral thesis is for the methods and instruments for financial risk management which exist in developed markets to be scientifically researched, upon which a conclusion is to be made about the possibilities of their application to enterprises in countries in transition. This type of research has its own social justification, in terms of creating the basis for quality decision making in domestic companies, which can also enable their better positioning in foreign markets

Surgical treatment of intradiploic epidermoid cyst treated as depression

Introduction. Extradural intradiploic epidermoid cysts are rare, representing less than 0.25% of all primary intracranial tumors. They can be neurologically silent and can only present psychiatric symptoms like depression, cognitive or personality changes. Case Outline. A 68-year-old male with two year long history of depressive mood, lack of motivation, helplessness, hopelessness and poor response to antidepressive drug therapy was described. CT scan showed a well-defined mass in the parietal scalp with destruction of the scull. He underwent intracranial tumor resection. Surgical resection and cranioplasty were performed. Pathology confirmed intradiploic epidermoid cyst. Conclusion. Total removal of these cysts and repeated washing of the cavity with 0.9 % saline may prevent recurrence and aseptic meningitis and may improve mental state of the patient. We also emphasize the need for neuroimaging studies in a patient with atypical changes in mental status, even without neurological signs or symptoms

Synoptic characteristics of an extreme weather event: the tornadic waterspout in Tivat (Montenegro), on June 9, 2018

Recently Montenegro has often been faced with extreme weather events. The aim of this paper is to provide a detailed synoptic analysis of a severe weather event, a waterspout, and to confirm an indication that in most cases such events could potentially be forecasted, which is of great practical significance, since human lives and property can be saved. The paper presents the research results of synoptic and mesoscale weather conditions which created a favourable meteorological environment for a waterspout development in Tivat (Montenegrin coast) on June 9, 2018, around 01 UTC (03 CET). Based on field survey analysis, the rating of tornado intensity by the Fujita scale (F-scale) has been done by assessing the damage. The synoptic type for this situation was CLOSED-SW and was determined by a detailed examination of atmospheric circulation. The results presented in the manuscript can help decision makers in Montenegro to take certain adaptation measures (above all, in tourism and construction) in order to mitigate the negative consequences of weather extremes

Fangcheng method as a tool for developing pre-algebra concepts in primary grade students

In this paper we give an overview of the Ancient Chinese fangcheng method for solving systems of linear equations and discuss some possibilities of using this method in teaching primary grade students. The history of mathematics shows us that students very often form mathematical concepts in a way similar to the ways these concepts have been formed through the history of mankind. Taking into account these and the results of previous research, we believe that it is possible to use fangcheng method to develop some pre-algebra concepts in primary grade students.Publishe

2-Amino-5-ethyl-1,3,4-thiadiazole as inhibitor of brass corrosion in 3% NaCl

The electrochemical behaviour of brass and anticorrosion effect of 2-amino-5- ethyl-1,3,4-thiadiazole (AETD) in chloride solution was investigated using electrochemical techniques. Results show that inhibition efficiency depended on inhibitor concentration and immersion time of brass electrode in inhibitor solution. Mechanism of brass corrosion inhibition by 2-amino-5-ethyl-1,3,4-thiadiazole includes adsorption of inhibitor on active sites on electrode surface. Adsorption of AETD in 3% NaCl solution obeys Langmuir adsorption isotherm

THE IMPACT OF LESSON STUDY ON Pre-service Kindergarten Teachers’ Mathematics Teaching Anxi

These articles are a result of the bilateral cooperation project ”Assumptions and possibilities of developing innovative models of teaching for accomplishing transparency of university education and for raising competitiveness in national and international knowledge markets”, carried out and financied by the University of Kragujevac, Faculty of Education, Jagodina (Republic of Serbia) and the University of Primorska, Faculty of Education, Koper (Republic of Slovenia), in the period 2017–2019.In today’s society teachers are expected to have adequate knowledge and skills to teach effectively even before graduation. Such expectations can cause anxiety in teachers, especially in inexperienced ones. Lesson Study is recognized as an effective tool for providing high-quality learning experiences for future teachers which enables them to learn from engaging in and observing teaching in contrast to traditional pedagogy courses. This study aimed to investigate the effects of Lesson Study on mathematics teaching anxiety of pre-service kindergarten teachers. The quasi-experimental design with two parallel groups was used. The sample consisted of 49 students divided into control (27) and experimental group (22). The students in the experimental group followed an adjusted Lesson Study design, while the control group followed the traditional way of teaching practice. The results showed that there was no significant difference in mathematics teaching anxiety scores between groups. However, there was a significant difference in the findings referring to ability to control the class favoring the experimental group. The findings of the current researchers’ study cannot be generalized due to certain limitations (small sample size, quasi-experimental design). The results can be used as support to encourage further investigations of the effects of Lesson Study in teacher education programmes.Publishe

Forest fires in Finland - the influence of atmospheric oscillations

In Finland, in the period 1996-2017, 28,434 forest fires were recorded (an average of 1,292.5 per year), and the total burned area was 11,922 ha (an average of 541.9 ha per year). In both cases, a statistically nonsignificant downward trend was recorded. Forest fires in Finland do not represent a particularly significant problem, primarily due to climatic characteristics, well-organized fire protection, and low density of population. The research of climate influence included the Atlantic Multidecadal Oscillation (AMO), the North Atlantic Oscillation (NAO), and the Arctic Oscillation (AO). The statistically significant values (p lt = .05) of Pearson correlation coefficient were recorded for the August values of NAO and the surface area of burned forest (-0.44), the June values of NAO and the average surface area of forest burned per fire (-0.51) and the May AO values and the average surface area of forest burned per fire (-0.45). For the June values of NAO and the average surface area of forest burned per fire, the Lomb periodogram shows four significant peaks, and the match is at two, at 2.4 and 3.4 years, which supports the hypothesis of the connection between NAO and forest fires in Finland
