AB  - In the past 20 years, extreme weather events (atypical variations of temperature and precipitation in space and time) have increased in Bosnia and Herzegovina, the consequences being significant material damage and decreased crop yields. The aims of the current paper were to investigate the impact of climate change on yield, irrigation requirements and water productivity of maize grown in one of the most important agricultural regions of the country. It used the results of projections of the EBU-POM regional climate model (Eta Belgrade University - Princeton Ocean Model) for the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A1B, A2 and A1B > carbon dioxide (CO2), A2 > CO2 for the 2020s (2010-2039), the 2050s (2040-2069) and the 2080s (2070-2099), and it compared them with the reference period (1961-1990) using measured and modelled data. AquaCrop was calibrated for the study area using data from experimental studies. The model was applied in simulations of future cultivation scenarios considering different irrigation regimes and variations in precipitation, temperature, CO2 concentration and sowing date. The results of simulations indicate that in the 2020s, there will be no significant changes in irrigation needs and yield due to the earlier sowing date and overall shifting of the growing season early in spring. A slightly larger negative impact of climate change will occur by the 2050s and a larger one by the 2080s due to a reduction in precipitation in the summer months. Compared with the reference period, in the 2080s, irrigation requirements are expected to increase by almost 100% (from 100 to 200 mm) and to provide up to 30% greater yield. In the future, water productivity of maize will remain high and will be even greater than current levels for both rainfed and irrigated cultivation due to anticipation and shortening of the growing season, reduction in crop evapotranspiration and increase in CO2 concentration. Due to an increase in precipitation in early spring and its reduction in the May-June period, the blue-to-green water ratio will increase in the future with positive environmental connotations. The productive use of blue water will also increase.

AB  - In this paper are presented the results of optimization of thermal and photovoltaic system of solar energy utilization aimed to reduce CO2 emission by energy efficient and cost-effective replacing fossil fuel and electricity with solar energy for heating of water for different purposes (for pools sanitary water, washing) in the Special hospital of the Spa Rusanda -Melenci. Crucial for success of the study is understanding and prediction of solar water heating systems dynamic behaviour and synergetic relations between energy efficiency, solar radiation intensity stochastic changes, and sanitary water consumption dynamics. Prediction and analysis of relevant subsystems dynamics was basis for the optimisation of the TES - Thermal Energy Storage role within the system energy efficiency optimisation. In addition, the possible integration of the waste water heat utilization using heat-pump energy recovery system and reheating using heat pump powered by the solar PV electricity are analyzed. Although, the solar water heating has much higher efficiency (thermal - 4 to 5 times higher than PV) the evaluation of given new technical solution confirmed its high energy efficiency and cost effectiveness. Necessary alternative energy, during the periods when there is not enough solar radiation, can be efficiently provided concerning the possibility to cover nearly 80-90% of water heating needs, if water waste heat and TES are used as a heat pump source.

AB  - Seven groups of sheep, with a total of 365 animals were used to determine the efficacy of treating ovine footrot by footbathing in aqueous zinc sulfate solution (20% w/v) or aqueous zinc sulfate solution (20% w/v) with added sodium lauryl sulfate (2% w/v). The average percentage of cured ovine feet in all trial groups ranged from 86, 11 to 96.61% of the number of affected feet. The cure rates were 94.71% for sheep that were foothathed in 20% zinc sulfate solution, and 96.61% for those footbathed in 20% zinc sulfate solution with added 2% sodium lauryl sulfate, when treatment was for 10 minutes every day for 14 days. When 45 minute footbathings, given three times at intervals of 4 days were examined, the cure rates were 91.27% for sheep treated in 20% zinc sulfate solution, and 92.85% for those footbathed in 20% zinc sulfate solution with 2% sodium lauryl sulfate. Treatment of sheep, involving 30 minute footbathings with 20% zinc sulfate solution, four times, intervals of 3 days, resulted in 88.64% cures. Fully healed feet were obtained in 86. 11% of sheep stood for 1 hour in a footbath containing 20% zinc sulfate solution with 2% sodium lauryl sulfate, and the treatment was repeated after 5 days. Surgical treatment did not have any significant effect on the percentage of cured feet compared with routine horn paring in the affected hooves. In cured sheep no reinfection was recorded for the next 30 days after therapy termination. The results obtained for curing affected sheep as well as the coparative advantages over other therapeutic agents, suggest that zinc sulfate and zinc sulfate with sodium lauryl sulfate are the means of choice for treating ovine footrot.

AB  - One hundred and five, one day old unsexed Hybro chickens divided into 7 groups, were fed basal diets supplemented with 0, 2, 5, 10, 20 and 30 mg Se/kg as sodium selenite for 6 weeks. The Se level of 2 mg/kg feed had no effect on chicken daily weight gain. The lowest level at which dietary Se caused reduction in daily gain was 5 mg/kg. Diets supplemented with 10, 15 and 20 mg Se/kg produced 24.5, 62.7 and 96.6% reductions in daily gain, respectively. Lower gains were evident within the first 11 days for chickens fed diets with 20 or 30 mg Se/kg and after 11 days for those provided with 10 or 15 mg Se/kg. Daily gain for the chickens fed the diet with 5 mg Se/kg was significantly lower only in the fifth week of fattening. Feeding diets with 15, 20 and 30 mg Se/kg caused 26.7 60 and 80% mortality, respectively Plasma Se concentrations were increased in all groups given supplementary Se. Maximal plasma Se levels between 220 and 300 mu g/l were reached on the 11th day (except for the group with 2 mg Se/kg) and at that level were maintained to the end of the experiment.
