In order to determine the effect of crystallization temperature on the absorption and properties of zeolite A particles, we have monitored the modified dibutyl phthalate absorption ( DBP ), a degree of crystalline phase, specific surface area, mean diameter of particle ( DS50 % ), and performed scanning electron microscopy ( SEM ) of the synthesized samples of zeolites. The synthesis of samples was carried out at crystallization temperatures of 70, 75, 80, 85 and 90°C ; the raw materials (sodium aluminate and sodium silicate) were heated at 90°C. The particle size of the synthesized samples is similar in most studied systems at all temperatures of crystallization, which is in accordance with the principles of the autocatalytic nucleation and „memory effect” of the gel. An increase in the specific surface area of the synthesized samples with the increase in the crystallization temperature was observed in all the analyzed systems (3.25 to 35.31 m2/g). It was found that the increase of crystallization temperature increases the absorption of dibutyl phthalate(0.90-1.20 cm3/g ); however, at the same time, the proportion of zeolite A in the same samples is reduced, as confirmed by SEM analysis.

The business efficiency, stable and long-term growth aims to accomplish each farmer who is engaged in intensive chickens fattening. In order to achieve this, there are concerns about the capacity utilization of farms for chickens fattening. It can be observe through stocking density. The stocking density is one of the most important factors that influence the fattening of chickens. That has a great impact on the economic efficiency. In determining the stocking density in intensive fattening it should take into account the welfare of chickens and the maximum density according to the Council Directorate 2007/43/EC. The other factors affecting on the economy of chickens fattening, such as: broiler hybrid, gender, type and feed conversion and health. In addition to these factors affecting the appropriate climatic conditions, mortality, the selling price of chicken meat that can be achieved in the market, the possibility of placement and billing as well as the cost of fattening. The goal of this paper was to determine the effect of density on productivity and production efficiency on Cobb 500 chickens. The research was conducted on 225 day-old chicks, which are arranged in the same 3m boxes. Performance and economics were performed economics of fattening, gross profit margin, gross profit per m and chicken, as well as per unit kg. The following densities were examined: control group (G0) was settled at a density of 15 birds/m as the Primljeno: 20.06.2014; Prihvaćeno: 06.07.2014 Recceived: 20-06-2014; Accepted: 06-07-2014 * Mr.sc.

Broj 33 Vol. XVI Vitez-Tuzla-Zagreb-Beograd-Bucharest, January June 2014. No. 33 106 technological norm, experimental group G1 of 13 chickens/m, G2 with 14 chickens/m, G3 of 16 chickens/m and G4 with 17 chickens/m. Terms of nutrition and environmental conditions were the same for all chickens. It is observed the efficiency of the sale of live chickens on the farm, per kilogram of body mass after 42 days of fattening. The best results is maintained control group G4 with the economic efficiency of 1,18 and a profit margin of 15.5%, and the worst results recorded control group G1 with the economic efficiency of 1,00 and no profit margin.

This paper presents the research of liquidity risk and its determinants in banking sector of Bosnia and Herzegovina (B&H). The aim of this paper is to to examine banks' exposure to liquidity risk in the context of 17 out of 28 commercial banks in B&H, by using data in the period 2002-2012. In the empirical part of the research the multiple regression analysis will be applied with the aim to test the statistical significance and explanatory power of selected variables using various data analysis techniques. For the purpose of analysis of the subject matter and the aim of the research, our paper is organized as follows: After background information about trends in liquidity position of banking sector in B&H and its development is provided in Section 1, Section 2 provides a brief overview of the conducted researches in recent years related to the determinants of the commercial banks’ liquidity. Section 3 describes models and variables used in the models & hypotheses. Section 4 analyzes and interprets the empirical findings the impact of explanatory variables on banks' exposure to liquidity risk. Finally, the research conducted in this study showed that most of the analyzed variables had a certain influence on determining the level of banks' exposure to liquidity risk Based on this research the commercial banks should further decide which a variable needs to be used in order to achieve desired level of liquidity.
