UDK 630*4:712(497.6 Sarajevo) This paper analyzes the health status of trees in the avenues of the city of Sarajevo. Special attention is paid to abiotic harmful influences, snow precipitation and mechanical damage of trees, as the initial factors of destabilization of their health status. Sarajevo area is characterized by a moderate continental climate occurring as a result of the influence of central European climate from the north and the Mediterranean climate from the south and of the variety of the terrain. This type of climate is characterized by hot summers and relatively cold winters. Because of severe thermal influence of the Adriatic Sea autumn is warmer than spring. Distribution of precipitation in Sarajevo is characterized by summer (primary) and autumn (secondary) peaks. Specific weather conditions in this area, in some years, result in early or late snowfall the consequences of which are damages of vegetation cover. The results of this research confirmed significant damages of the trees resulted from the adverse effects of snow in October 2009 (branches fractures, split of the stem and fracture of tree crowns). The resulting injuries are suitable openings for the penetration of rot causing microorganisms (fungi and bacteria) and colonization of insects which is why we can expect further deterioration in the health status of trees in the future. The paper suggests activities the implementation of which can reduce these harmful effects of biotic factors.

UDK 630*6/.9(497.6) This paper deals with the forestry production cost analyses realised in Federation of B&H. The results of research point out on high differences of production costs between individual forest enterprises, caused by various ways of cost calculation, as well as by various production conditions. Therefore, the data obtained from enterprises are not comparable in whole, and as such, the data could not be used as the bases for calculation of an objective forestry production cost. To effect the activity based costing (e.g. activity of silviculture or forest utilization) is of particular importance. The used methodology is based on traditional costing, which is appropriate only for calculating direct costs, and not adequate to determine overhead (indirect) costs. Regarding these costing methods for calculating costs in forest enterprises, their performed forest activities are not appropriately valued. Today, as overhead costs are of considerable importance, the demand for more accurate costing methods has increased in the field of forest management. ABC (Activity Based Costing) method is a new dimension of cost analysis to record costs for each forest activities, towards objective forest management cost production determined. At the same time, it reveals the necessary costs for each activity, assures the proper layout of overhead costs to the forest activities. On the base of the defined forest activities for realization of forest management goals, as well as forest production capacities, we could understand the forest enterprises ability to achieve the goals and also to pay rent for using forest resources.

Properties of the Zagreb indices of pseudo-regular graphs are established, with emphasis on the Zagreb indices inequality. The relevance of the results obtained for the theory of nanomolecules is pointed out.

UDK 631.4:546.19 A simple and inexpensive method for the determination of inorganic As(III) and As(V) at low ppb levels was developed. The method is based on formation of hydride from a sample solution and its reaction with mercury bromide on a solid support. Formation of a yellow-brownish product was optically detected. Amidosulfonic acid was used as a reaction medium for determination of total inorganic arsenic, while citrate buffer (0.1 mol/dm3, pH=5.5) was used as a reaction media for determination of As(III) alone. As(V) was calculated as a difference of total inorganic arsenic and As(III). This method has been applied to soil extracts. Extraction of inorganic arsenic from soil samples was done in three-step sequential extraction with the following extractants: NH4H2PO4 (0.05 mol/dm3); NH4-oxalate buffer (0.2 mol/dm3, pH=3.25); and mixture of NH4-oxalate buffer (0.2 mol/dm3) and ascorbic acid (0.1 mol/dm3) at pH=3.25. The method was suitable for determination of inorganic arsenic species in soil extracts covering concentration range of the analyte between 0.2 - 20 ppb.

This article describes the methodology of preparation, writing and publishing scientific papers in biomedical journals. given is a concise overview of the concept and structure of the System of biomedical scientific and technical information and the way of biomedical literature retreival from worldwide biomedical databases. Described are the scientific and professional medical journals that are currently published in Bosnia and Herzegovina. Also, given is the comparative review on the number and structure of papers published in indexed journals in Bosnia and Herzegovina, which are listed in the Medline database. Analyzed are three B&H journals indexed in MEDLINE database: Medical Archives (Medicinski Arhiv), Bosnian Journal of Basic Medical Sciences and Medical Gazette (Medicinki Glasnik) in 2010. The largest number of original papers was published in the Medical Archives. There is a statistically significant difference in the number of papers published by local authors in relation to international journals in favor of the Medical Archives. True, the Journal Bosnian Journal of Basic Medical Sciences does not categorize the articles and we could not make comparisons. Journal Medical Archives and Bosnian Journal of Basic Medical Sciences by percentage published the largest number of articles by authors from Sarajevo and Tuzla, the two oldest and largest university medical centers in Bosnia and Herzegovina. The author believes that it is necessary to make qualitative changes in the reception and reviewing of papers for publication in biomedical journals published in Bosnia and Herzegovina which should be the responsibility of the separate scientific authority/ committee composed of experts in the field of medicine at the state level.

We present explicit formulas for the values of augmented eccentric connectivity indices of single-defect nanocones. Our main result is that the augmented eccentricity index of an $n$-layer nanocone with a single $k$-gonal defect at its apex behaves asymptotically as $27k(1 - \ln 2) n$ for $k \geq 5$.

The goal of this paper is to analyze banking regulation in Bosnia and Herzegovina and the progress made by banks in the management of banking risks. Basel Committee on Banking Supervision requires banks to establish a reasonable infrastructure for risk management. This infrastructure should identify, measure, monitor and control the risks that the bank is exposed to their operations. In this sense, the work was carried out research on the management of credit risk, liquidity risk and operational risk in order to gain knowledge about the progress of the banking sector in Bosnia and Herzegovina on the implementation of Basel 2. This paper represents the results of a research carried out on twenty out of thirty planned banks in Bosnia and Herzegovina that were surveyed during 2009, which makes 66.6% of the total sample (or 83.17% of total assets of the banking sector in Bosnia and Herzegovina). Summarized results of the questionnaire also showed further progress of the banks in complying with Basel 2, although it turned out that they often react to developments and changes without the existence of necessary infrastructure and business culture to keep it.
