Introduction:The aim of the study was determining the type of weapon and shooting distance depending on chemical analysis of inorganic gunshot residue from the skin gunshot wounds in experimental animals (pigs).
Methods:Experimental study was conducted in order to determine components and their percentage in gunshot residue (GSR). In 60 samples, pig skin was shot by fi ring projectiles from four different weapons and from three different distances (contact wound and near contact wound from 5 cm and 10 cm). The methodology included determining the presence of inorganic material: antimony, barium, lead, nickel, zinc and copper in the skin and subcutaneous tissue using atomic absorption spectrophotometry (AAS).Results: Formula for determining weapon type was provided cutt-off points for different weapons, with 78.6% of original grouped cases being correctly classifi ed. Formula for determining weapon type was provided cutt-off points for different distances, with 58.9% of original grouped cases being correctly classifi ed, which was slightly less reliable compared to weapon type discrimination analysis.

The aim of this study was to look for any secular trend in the stature of Balkan populations from the time of World War II (1939-1945) to the Balkans War (1991-1995). The research was based on the examination of exhumed skeletons of 202 men killed in World War II in the area of the Republic of Slovenia, and 243 men killed in the Bosnian War in Bosnia and Herzegovina. The length measurements of the right and left humerus, femur, tibia and fibula were taken. Since the results revealed no significant differences and the left-sided bones were more complete and recurrent in the sample, the bones of the left side were used in the analysis. Since the increase in height depends mostly on the increase in length of the long bones, with an average absolute change of about 0.28 cm for humerus, 0.55 cm for femur, 0.49 cm for tibia and 0.20 cm for fibula per decade in our case, these results suggest a significant increase of the height of the Balkans population. The difference of the sum of the average femur and tibia length for the study period was 4.13 cm. Recalculated average length increase of the sum length of femur and tibia per decade was 0.88 cm for the left side. Our study revealed that there was a trend towards increased long bone lengths, at least in the male population analyzed.
The paper explores the possibilities of creating an econometric model for making short-term forecasts of the Gross Domestic Product of Bosnia and Herzegovina (GDP of B&H). Its aim is to determine the most representative and most efficient model for forecasting the quarterly GDP of B&H. This is the first paper that simultaneously compares ARIMA models, bridge models and factor models in three different time periods. All variables are available for the period of 2006q1-2016q4. The final choice of the model for forecasting the quarterly GDP of B&H was selected on the basis of a comparative analysis of the predictive efficiency of the analysed models. Based on the obtained results, the most efficient model for forecasting quarterly GDP of B&H is the bridge model, which includes four variables as regressor: Retail sale of other goods, Total loans, Manufacturing and Manufacture of food products.
