The aim of the research is to determine relationship between the price of corn in the current year and the number and price of fattening pigs in the following year. The analysis was done for the period from 2006-2021. Descriptive statistics were used for data processing. To determine the impact of corn price on the price and number of fattening pigs, a regression model was applied. A moderate variability of the observed parameters was determined, with increasing of corn price at a rate of 7.92% per year, fattening pigs 3.88%, and the number of fattening pigs decreasing by rate of 1.75%. The results of the regression analysis indicate a significant impact of the corn price on the number and price of fattening pigs.

Heat exchangers are one of the most frequently used elements in the process industry. Water is usually used as a heating fluid and often is not chemically prepared, i.e. it has bicarbonate, calcium, and magnesium, which make the water temporarily hard and form incrustations on the primary side of the heat exchanger. The paper shows a device for chemical cleaning of the heat exchanger without disassembling it and when the secondary side of the heat exchanger is actively working. Tests of the device in operation were carried out in the machine plant of the Tonanti Hotel in Vrnjačka Banja from 2021 to 2022, where it showed high reliability and complete independence in operation.
热交换器是过程工业中最常用的元件之一。水通常用作加热流体，并且通常不是化学制备的，即它含有碳酸氢盐、钙和镁，它们使水暂时变硬并在热交换器的一次侧形成结痂。介绍了一种换热器二次侧主动工作时，无需拆卸换热器进行化学清洗的装置。该装置的运行测试于2021年至2022年在vrnja ka Banja的Tonanti酒店的机器工厂进行，在那里它显示出高可靠性和完全的运行独立性。

Field trials with 11 maize hybrids (9 newly released and two standards) of the FAO maturity groups 300-600 were sown in four locations. The aim of the work was to recommend hybrids for individual location based on their reaction to different agroecological conditions, as well as to evaluate the possibility of replacing later hybrids with hybrids of earlier maturity groups, with certain changes in agrotechnics. ZP hybrids of the latest generation showed high grain yield potential and stability, as well as wide adaptability to different ecological conditions, degree of soil fertility and application of agrotechnical measures. A significantly higher grain yield of all hybrids compared to other locations was at the Valjevo location, that is, the location with the highest amount and favorable distribution of precipitation during the growing season. In these trials, maize hybrids of different FAO maturity groups were grown with the same number of plants per unit area. For maize hybrids with shorter vegetation, which are characterized by a lower plant height, a greater number of plants per unit area is recommended, compared to hybrids with a longer growing season. With changes in agrotechnics in this direction, along with the advantages of earlier hybrids, which are seen in avoiding critical periods for water, the grain yield of earliy hybrids could reach the yield level of later hybrids.

Brassica oleracea var. acephala (kale) is a worldwide known vegetable plant, known for its heavy metal accumulation abilities. This study analyzed the phytoremediation potential of domestic BiH kale varieties, grown in a controlled environment and with different concentrations of Cadmium (Cd). Cd is a known pollutant found in small concentrations in soil under normal environmental conditions. Real-Time PCR was used to analyze the gene expression activity of Cd heavy metal correlated genes (MAPK2 and NRAMP6). The root analysis assay confirmed shorter root length after Cd treatment, confirming severe Cd impact on plant cell growth, implying shorter growth in roots in all treated kales. Gene expression results showed that Cd triggers the expression of MAPK2 and NRAMP6 suggesting their significant involvement in Cd metabolizing processes. Based on the combined results, kale from the Stolac region is found to be the most resistant variety, while the only hybrid kale, accumulates the most Cd suggesting its phytoremediation potential.
甘蓝(Brassica oleracea var. acephala)是一种世界闻名的蔬菜植物，以其重金属积累能力而闻名。本研究分析了在不同镉浓度环境下生长的国内黑黑省羽衣甘蓝品种的植物修复潜力。Cd是一种已知的污染物，在正常环境条件下，土壤中的浓度很低。采用Real-Time PCR分析Cd重金属相关基因MAPK2和NRAMP6的基因表达活性。根系分析结果表明，Cd处理后的羽衣甘蓝根长变短，表明Cd对植物细胞生长有严重影响，说明所有处理的羽衣甘蓝根长都变短。基因表达结果显示，Cd触发MAPK2和NRAMP6的表达，表明它们在Cd代谢过程中具有重要作用。综合结果发现，来自Stolac地区的羽衣甘蓝是抗性最强的品种，而唯一的杂交羽衣甘蓝积累的Cd最多，表明其具有植物修复潜力。

The time of basic tillage and fertilization are very important agrotechnical measures that have a high impact on soybean yield. Winter basic tillage of the soil reduces the harvest yield by 8.53%, and spring tillage by 21.18%, the application of NPK fertilizers increased the yield by 13.96%, the foliar application of water extract from plant material by 9.57% and the application of AN by 8.44%. Autumn basic tillage is most conducive to achieving high and stable soybean yields, and fertilization has a positive effect on soybean yields.

The aim of this research was to examine the influence of partial and total replacement of pork backfat with two quite different (in terms of sensory properties) plant oils (grapeseed and pumpkinseed oil) on instrumental colour and texture of frankfurters. The influence on colour was more pronounced when pumpkinseed oil emulsion was used as backfat replacer – these frankfurters were less red and more yellow than control and frankfurters with grapeseed oil emulsion. The effect was more pronounced with the increase of backfat replacement degree. No significant influence on instrumental texture parameters was observed.

Viable Saccharomyces cerevisiae cells were immobilized by silicaalginate matrix and obtained spherical composite particles and used for biosorption of Cd(II) ions. The obtained composite displayed high cadmium removal efficiency of 99.2, 95.7, 88.3 and 78% in the successive four adsorption steps. The adsorption capacity after four step of Cd(II) removal was ~14,2 mg of Cd(II) per g of biosorbent. Pseudo-second-order kinetic agree well with the experimental values suggesting both adsorption and ionic exchange are simultaneously performed on the surface of used biosorbent.

The main goal of this study was to determine the impact of the type of packaging to health safety sausage, and therefore the microbiological compliance with the requirements of the Regulation on microbiological criteria for foodstuffs. The study included the determination of the presence of bacteria of the genus: Salmonella, E.coli, Enterobacteria, Campylobacter, Listeria monocytogenes, and sulfitereducing Clostridiae as well as the total number of bacteria within each individual product. According to estimate the effect of the type of packaging (vacuum, MAP and bulk) to the safety of sausages was performed collecting samples of sausages packed in a vacuum packaging, modified atmosphere packaging of bulk and different manufacturers for each type of packaging. As a result of the study, out of 10 analyzed samples, bacteria from the Enterobacteriaceae family in the range of values from 1.8 to 2.55 CFU/mL., E. coli, in the range of 0, were found by isolation on selective mediafrom 0.51-1.23 CFU/mL. Total bacteria ranged from 2.6-4.02 CFU/mL. Yeasts and molds in the samples tested were between 2.22 – 3.84 CFU/mL. Microbiological tests did not reveal any bacteria from the following groups: Salmonella spp., Listeria and sulphite-reducing Clostridia. It was found that all samples correspond to the Regulation on microbiological safety.

Meat colour was evaluated in 36 goat kids of both genders equally from three breeds: Alpine, Balkan and Serbian white breed. Animals were slaughtered at 18 kg of body weight and three muscles were analysed for colour characteristics and pH value: m. longissimus lumborum, m. psoas major (tenderloin) and m. semimembranosus. pH values differ significantly only for m. longissimus lumborum muscle, whereas Balkan kids had a significantly higher pH value than Alpine and Serbian white (p<0.001). The goat breed significantly affected meat CIEL*a*b* values for all muscles analysed. Lightness (L*) was generally the highest for Balkan and lowest for the Alpine breed. The differences in redness (a*) and Chroma values (C*) were not significant, while the yellowness only differed for m. longissimus lumborum muscle, whereas Serbian white kids had higher b* values compared to Alpine kids. As a colour saturation characteristic, the hue angle was higher in meat from indigenous breeds (Balkan and Serbian white) than in the Alpine breed.
