Disposal and incineration or recycling of old and waste wood represents an environmental problem. In most cases, agents on the basis of chlorinated phenols were used for wood preservation. These substances penetrate deeper into the wood and because of their chemical stability it remain for decades. This is an environmental problem since chlorinated phenols are among the most acute and chronic toxic contaminants. One of the promising methods to resolve this problem is biodegradation of chlorinated phenols by microorganisms and by fungi, lately. The toxicity of chlorinated phenols against ligninolytic fungi Hypoxylon fragiforme (Hf) and Coniophora puteana (Cp) has been investigated in this paper. Results showed that the maximum concentration of chlorinated phenols, that allows the growth of Hp and Cp fungi, is 2.5 mmol/L. Testing the impact of eight chlorinated phenols on the growth of fungi, it was determined that chlorinated phenols show less antifungal activity to Hp fungus. Antifungal activity to both fungi increases with the number of substituted chlorine atoms. Also, an important role in antifungal activity, have a physico-chemical properties of chlorinated phenols, primarily LogKow, pKa and the Henry constant. Position of chlorine atoms in the molecule also has a certain influence.

Various phenolic compounds can be found in a gymnosperms and have been related to their bioactive properties, esspecially as a allelochemicals. Total phenol, flavonoid (flavone and flavonol) and protoanthocyanindin content was estimated quantitatively by using spectrophotometric method in the needle methanol extracts of mature Cryptomeria japonica, Cupressocyparis × leylandii „Castewellan Gold“ and Sequoiadendron giganteum individuals. Although there is a strong intraspecific variability on the basis of the studied group of compounds, Duncan's test showed that C. japonica is clearly distinguishable from the other two taxa analyzed, and in particular on the basis of total proanthocyanidins and phenolics content. On the other hand, S. giganteum and C. × leylandii only differ on the basis of the flavonoid content calculated in terms of quercetin equivalent. In all three taxa proanthocyanidins had the highest variability. The ratios and relatively high content of analyzed phenolic compounds for all three studied taxa indicate that they may be considerd as a potential both chemotaxonomic characters and valuable sources of antioxidants, which should be confirmed by further researchs.

Investments in forest sector represent an important issue that is regulated by legislation. Legislative framework that regulate forest sector in the Federation of Bosnia and Herzegovina has been changing recently - from the Law on Forests of the Federation of Bosnia and Herzegovina (2002 – 2009), Forest Regulation of the Federation of Bosnia and Herzegovina (2009 – 2012) and finally cantonal Laws on Forests (2012 to date). Cantonal laws currently represent the only valid legislative documents that regulate forest sector in the Federation of Bosnia and Herzegovina. This paper analyse the investments in the public forests at the territory of Una-Sana Canton, managed by forest management enterprises "Unsko-sanske šume", within the period 2003-2013 in dependence of the valid legislative frameworks. Having in mind the various regulations that prescribed the financing of the biological investments, scope and structure of the performed activities together with the amount of invested funds have varied between particular periods. The biggest share in total investments to forest sector belongs to the silvicultural measures (66%) and forest road construction (17%). The analysis included the trend of realised biological investments and invested funds. It reveals the mutual incompatibility that causes the differences in unit costs of biological investments in various periods. This implies the need for creation and implementation of unique methodology for cost calculation respecting the basic principles of econometrics. Conducted analysis indicated that previous legislative frameworks did not prescribe appropriate financing model. One should bare in mind this fact during the prescription of new financing model in the ongoing proposal of new Law on Forests of the Federation of Bosnia and Herzegovina.

Forests as one of the largest renewable sources in nature, are extremely important for human survival. They cover about a quarter of the Earth's surface and are the lungs of all living beings. Rapid technological development has significantly improved the life of a man, but also made a great contribution to the destruction of the natural balance, and reducing biodiversity.
They represent a significant social wealth not only by producing precious and for its quality values in many ways irreplaceable wood material, edible and medicinal plants, but also because its existence is a very positive impact on the protection and improvement of the environment, regulation of climate and water regime, reducing damage from erosion, flood and spate, development of recreation, tourism, hunting and many other economic activities. Fires are one of the strongest and most dangerous agents that man were served in suppressing forest since ancient times, but unfortunately still used today. In many parts of world man suppresses forest and brush with fires, creating a short-term favorable conditions for its economy.
Research that are the subject of this paper is an analysis of the volume of forest fires in the period 2009-2013 year in the municipality of Konjic. The conducted analysis in this area in the period 2009-2013 year recorded 37 fires. Of that number, 20 fires were in the category of crown-fires and 17 ground-fires. The largest number of fires was 14 in 2011, with 310 hectares of fire-affected areas, while the lowest number was recorded in 2010, only three fires and burnt area amounted to 7 ha.

Plants produce a numerous and diverse secondary metabolites, organic compounds which are not essential and do not participate directly in the growth and development, but may have very important role in their adaptation and adjustment to particular environmental conditions. For humans, secondary metabolites are very important in medicine, pharmacology, food and cosmetics industries. The presence of eight types of secondary metabolites (anthocyanins, coumarins, emodins, fatty acids, phenols, saponins, steroids and tannins) in water extracts of leaves and barks of 25 broadleaf deciduous species from 15 families was qualitatively investigated by rapid phytochemical screening methods. According to literature data, in this study for the first time is determined the presence of six types of secondary metabolites in analyzed dendro species: anthocyanins in one species; both coumarins and phenols in five species; emodins in six species; saponins in eight species; and tannins in four species. Particular attention in further research should be given to Fagus sylvatica L., Populus tremula L., Quercus petraea (Matt.) Liebl., Robinia pseudoacacia L. and Sorbus aria (L.) Crantz. Since preliminary results of this study are promising it would be desirable both to identify active compounds and assess their potential antimicrobial and antioxidant activities.

Helleborus multifidus Vis. is endemic Illyric-Adriatic species with distribution range in Italy, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro and Albania. Although few studies reported different taxonomic categories for H. multifidus, this one is the first using molecular-genetic markers (trnL region and matK of chloroplast DNA and nuclear ITS1 and ITS2 region) for genetic characterization of H. multifidus presented at three localites in Bosnia and Herzegovina. The results revealed that PCR-RFLP on trnL intron was not informative for testing inter- or intrapopulation diversity. Contrary, analysis of matK, ITS1 and ITS2 sequences showed differences between populations from Trebinje region and Kupreško polje, pointing to the need to include additional analyses in order to confirm these findings.

Bark beetles are the most important pests of the coniferous forests. Although they are considered to be a secondary pest, they are becoming the primary pests that attack healthy trees. One of the important spruce bark beetle is the Pityogenes chalcographus (L.) - a small spruce beetle. The research was conducted in the municipality of Vareš, on three locations: Ponikva, Pobrin Han, Doli. The active period of the bark beetle for development began in the last decade of April. P. chalcographus in the field of research had two generations. For the development of generations it took between 12 and 13 weeks. Weather conditions in the object of research did not allow the completion of the second generation. The activity of the bark beetle ends in mid-September. When we talk about the characteristics of wood material which prefers small bark beetle of spruce, we can say that he prefers to inhabit thinner parts of trunk with thin and smooth rind. In the object of research for monitoring of population of bark beetle P. chalcographus was used trap trees. As a measure to combat the small spruce bark beetles are strongly advised in due time, autumn and winter, remove the dried trees and trees with drilled bark beetles. Maintenance and establishment of forest order to reduce the amount of wood material suitable for the settlement of bark beetles.

In expert activities of forest managements, the forest stand volume is most frequently determined by way of volume tables, the so-called management tariffs. For an evaluation of stand volume using this method, the method of volume tables, it is necessary to know the site class (rating) of the stand for present tree species that is used as an argument for the selection of suitable volume progression (management tariff). The site quality for certain species in mixed stands is determined by comparing the height of trees at certain diameters at breast height (dbh) with the height of appropriate dispositions of height site class curves. In so doing the focus is placed on the ratio between the heights of large diameter trees, and the quality of the stand is rated within an interval of more defined site quality classes. For the purposes of a more objective and simpler assessment of site quality, there have recently been attempts to make site quality assessments mathematically, using appropriate formulas in which tree heights or average heights by diameter classes and heights determined by mathematical functions of site class curves are used. For economically important tree species in Bosnia and Herzegovina (fir, spruce, beech, sessile oak, black pine and scots pine), the dispositions of height site class curves (and classes) are constructed graphically and mathematical functions for them are not known. A large number of mathematical models that are often used to represent growth trends and that satisfy the needs of height curves is analyzed in this paper with a view to determining the most suitable regression model for simulating height site class curves for fir in high forests in Bosnia and Herzegovina. The expanded Prodan model (with an additional item in the denominator) has been selected as the most suitable one on the basis of statistical indicators of the regression model quality.

This study aimed to analyse and compare the total phenolic content and the antioxidant activity of aqueous extracts of three medicinal plants: hibiscus (Hibiscus spp.), rosemary (Rosmarinus spp.) and savory (Satureja spp.). The plant extracts were prepared using maceration process. The total phenolic content was determined spectrophotometrically with the Folin-Ciocalteu reagent using gallic acid as a standard and the antioxidant activity was analysed using the Briggs-Rauscher reaction method. The inhibition times produced by plant extracts on an active Briggs-Rauscher oscillating reaction mixture were recorded potentiometrically. The total phenolic content was found 0.27, 1.29 and 1.43 mgGAE/g of dry extract for hibiscus, rosemary, and savory, respectively. Good correlation was found between the total phenolic content and the Briggs-Rauscher inhibition times (R2 = 0.994).

The development and application of new techniques and technologies in hunting management, scientific research and professional work in the hunting domain is a continuous process. Numerous technical achievements are often applied and targeted operationally in hunting and the exploration of game and its habitat.
When analysing the past period, and the latest technical and technological achievements in hunting, one can point out several very significant examples of the application of new techniques and technologies in hunting, such as:

The development and application of live game capture methods, with particular emphasis on catching chamois in Bosnia and Herzegovina;
Chemical immobilization (tranquilizing) in research or transport of live game;
The use of sensory cameras (photo traps) for game tracking and surveillance of the hunting grounds (ordinary sensory cameras, IC cameras);
Telemetric tracking of game, from large carnivores up to small game species with classic devices and GPS devices;
Measuring microclimate elements with precision instruments on selected micro locations in wildlife habitats;
Use of sensory sound repellents for game-avoidance (ultra - and infrared devices);
Use of lightweight unmanned aerial vehiclesfor wildlife habitat analysis using a classical camera;
Use of lightweight Unmanned aerial vehiclesto determine the numerous status and game structure using a thermal imaging camera;

All the above-mentioned techniques and technologies have given, and make, a significant contribution to the scientific research work in the field of hunting and to a large extent in the daily operational application of hunting management, monitoring and protection of game and animal species.
Quantum Physical Interpretation of Thermoelectric Properties of Ruthenate Pyrochlores
Authors: Akhbarifar Sepideh 
Published: January 2022

Lead- and lead-yttrium ruthenate pyrochlores were synthesized and investigated for Seebeck coefficients, electrical- and thermal conductivity. Compounds A2B2O6.5+z with 0 ≤ z < 0.5 were defect pyrochlores and p-type conductors. The thermoelectric data were analyzed using quantum physical models to identify scattering mechanisms underlying electrical (σ) and thermal conductivity (κ) and to understand the temperature dependence of the Seebeck effect (S). In the metal-like lead ruthenates with different Pb:Ru ratios, σ (T) and the electronic thermal conductivity κe (T) were governed by ‘electron impurity scattering’, the lattice thermal conductivity κL (T) by the 3-phonon resistive process (Umklapp scattering). In the lead-yttrium ruthenate solid solutions (Pb(2-x)YxRu2O(6.5±z)), a metal–insulator transition occurred at 0.2 moles of yttrium. On the metallic side (<0.2 moles Y) ‘electron impurity scattering’ prevailed. On the semiconductor/insulator side between x = 0.2 and x = 1.0 several mechanisms were equally likely. At x > 1.5 the Mott Variable Range Hopping mechanism was active. S (T) was discussed for Pb-Y-Ru pyrochlores in terms of the effect of minority carrier excitation at lower- and a broadening of the Fermi distribution at higher temperatures. The figures of merit of all of these pyrochlores were still small (≤7.3 × 10−3).

The results of ground-penetrating radar (GPR) studies of permafrost and aerial photography, carried out at key sites in the Sentsa River valley (Oka Plateau, Eastern Sayan Ridge), are presented.For geophysical studies, an OKO-2 GPR completed with an AB-90 shielded antenna unit was used with a maximum sounding depth of up to 20 m and a resolution of 0.5 m. To account for the landscape elevation, the Trimble TS635 tacheometer and the Leiсa DISTO D 510 rangefinder performed hypsometric measurements with a step of 1.0 m. Aerial photography was carried out by a remotely piloted aircraft (RPA) DJI Inspire 1 Pro, equipped with a Zenmuse 3X camera (a resolution of 3840×2160 pixels) with a spatial resolution of 5.7–7.8 cm/pixel (in different years).In the structure of frozen lacustrine-alluvial sediments, three GPR complexes are distinguished, corresponding to the active layer and frozen rocks with different amounts of schlieren, lenses and layers of texture-forming ice. The orthophoto map and tacheometric survey analysis showed that the destruction of frost mounds occurs from the second half of April to the first half of October. The most significant relief change is due to the thawing of icy pulverescent clayey silts. It leads to subsidence blocks in the ledge of the Sentsa River terrace. Lateral river thermoerosion also contributes to the frost mounds destruction.
Dominacija izdašnosti nad pravičnošću u oporezivanju dodate vrednosti
Authors: Veličković Jovana , Đorđević Marina 
Published: January 2022

U savremenim poreskim sistemima postoje različiti oblici oporezivanja potrošnje a najzastupljeniji među njima je porez na dodatu vrednost. PDV predstavlja jednu od najznačajnih kategorija poreskih prihoda, s obzirom na to da ga karakteriše visok stepen izdašnosti. Međutim, osnovni nedostatak poreza na dodatu vrednost jeste to što raspoređuje poreski teret regresivno u odnosu na prihode poreskog obveznika. S obzirom da relativni udeo potrošnje u dohotku pada kada dohodak raste, porez na dodatu vrednost, utvrđen po jedinstvenoj stopi, teže pogađa siromašnije nego bogatiji deo društva. Cilj rada je da pokaže dominantan odnos principa izdašnosti u odnosu na pravičnost u oporezovanju dodate vrednosti, da ukaže na postojanje problema regresivnosti i na moguće mere koje se mogu primeniti radi zadovoljenja principa pravičnosti u oporezivanju.
