For determination of poultry quality shortly after slaughtering, physical criteria (pH-value, conductivity, colour, juice retention) are of importance. However, they are affected by breeding, transport, cooling and the storage period. PH-values of breast meat (genetically structured material) were recorded shortly after slaughtering (15 min p.m.) and differences between breeding line and gender were found (n=5109). The pH1-values ranged from 5.50 to 6.79. Male broilers showed significantly lower pH1-values than female ones (6.02:6.10). There were also significant differences concerning breeding line and gender. Meat quality (PSE, DFD) of broilers can be recorded quickly and accurately determining the pH1-value of breast meat. Threshold ranges to be considered are ≤ 5.8 (PSE), 5.9-6.2 (standard meat properties) and ≥ 6.3 (DFD). This classification is not to be compared to the deviation of pork.

Healthcare workers (HCW) can have an important role in educating parents about child road safety, but research on the topic shows that they usually do not have adequate knowledge. Thus, the aim of our study was to analyze their knowledge in the field of child road safety.

Background: Cervical cancer is a major global health problem, and one of the most common causes of cancer in women. This descriptive epidemiological study aimed to provide an overview of the cervical cancer incidence and mortality in Vojvodina. Methods: The data from the Serbian Cancer Registry regarding the cervical cancer incidence and mortality for the period 2016-2021 were analyzed. Results: During the observed 6-year period, the average age-standardized incidence rates of cervical cancer in Vojvodina and Serbia were 20.4 and 19.1 per 100,000 women, respectively. The average age-standardized incidence rates by the district of Vojvodina ranged from 16.8 to 30.2/100,000. The average age-standardized cervical cancer mortality rate in Vojvodina and Serbia was 7.0 and 6.6/100,000, respectively. The average mortality rates by the district of Vojvodina ranged between 5.6/100,000 and 9.9/100,000. Conclusion: The cervical cancer incidence and mortality rates in Vojvodina exhibited significant variation across different districts and observed years, with their average values surpassing the national average. To improve the epidemiological situation of cervical cancer in Vojvodina, it is imperative to enhance the implementation of organized screening at the district level, coupled with intensified efforts to promote HPV vaccination throughout Vojvodina. Additionally, more research on screening coverage and vaccination rates and improved reporting cervical cancer cases and deaths are needed.

The autochthonous, i.e. local, red wine variety Prokupac is one of the most important varieties in Serbia. In the past, this variety was the leading one in the largest number of wine-growing areas of our country. The Prokupac variety is currently the most represented in the Tri Morave wine-growing region (Central Serbia), while the largest number of vineyards with this variety are located in the Župa wine-growing subregion. Due to its importance as an old and traditional variety, certain researches of this variety have been initiated in recent years in wine-growing areas where Prokupac is traditionally grown. Certain scientific activities were initiated to isolate different genotypes with improved production and use value, all with the aim of clonal selection of this variety. In this paper, some characteristics and quality parameters of the more promising Prokupac genotypes that were isolated in the Župa wine-growing subregion in the Aleksandrovac municipality are presented. More extensive research was carried out on grapes from the harvest of 2019, 2020 and 2021 with 16 selected genotypes, namely eight genotypes from the Latkovac locality and eight genotypes from the Drenča locality. In addition to laboratory analyses of sugar, acid and pH content in the grape must, the theoretical alcohol content was also calculated. Furthermore, spectrophotometric methods were used to determine colour intensity A-420, colour intensity A-520, colour intensity A-620 and total colour intensity, as well as colour tonality. The analyses showed that certain main quality parameters from the research are within the value limits as in earlier research, but that the acid content is generally more optimal for red wine varieties compared to the research of that parameter carried out in the earlier period in other wine-growing areas (Fruška Gora and Čegar wine-growing subregions). Moreover, in our research, the sugar content of the grape is higher than the established values of that parameter in the grape must from the Čegar wine-growing subregion.

In this work, removal of heavy metals (Cr, Mn, Co, Ni, Cu, Zn, As, Cd, and Pb) from fly ash has been studied using acid leaching and wet oxidation methods. In parallel, microwave-assisted acid digestion was applied for determination of pseudo-total concentrations of heavy metals to estimate the leaching efficiency. Multivariate statistics (Pearson correlation, principal component analysis, and hierarchical cluster analysis) have shown two dominant groups of elements, depending on their characteristics and affinity towards the ash solid phase. Thus, Cr, Zn, Mn, Co, and Ni belong to the group I, while Pb, As, Cd, and Cu belong to the group II. It was demonstrated that the wet oxidation method was more suitable than acid leaching since the reduction in metal concentration was 30 to 75 % compared to 12 to 25 % obtained by acid digestion. The influence of fly ash treatment on the residue characteristics was investigated by X-ray diffractometry and scanning electron microscopy. The analyses revealed surface and structure changes of fly ash after the wet oxidation treatment. Overall, wet oxidation could be an appropriate treatment for heavy metal removal from fly ash, providing a material that could be further used, thus reducing the risk of pollution caused by the disposal of coal combustion fly ash.

Research of uvological characteristics is one of the obligatory steps for determination of general production and technological value of grapevine varieties. Such research is particularly recommended for local varieties that did not previously show sat­isfying characteristics necessary for production of high-quality wine. Local grapevine varieties Smederevka (white wine variety) and Žametovka (red wine variety) have mostly served for production of low-quality wine in the past. With changes in the manner of pro­duction in the sense of focus on high-quality wine and production of wine with geograph­ical indications, vineyards planted with these varieties in Serbia have mostly been grubbed up. However, due to the characteristic and favourable terroir conditions, they have survived in the Trstenik wine-growing district (subregion within the Tri Morave wine-growing re­gion). With the aim of determining uvological characteristics of these two varieties in current climate conditions that are favourable for these high-yield varieties, this paper examines the mechanical composition of grape bunches (bunch weight, number of berries, stem weight), mechanical composition of berries (weight of 100 berries, weight of skin of 100 berries, weight of mesocarp of 100 berries and weight of seeds of 100 berries), as well as grape must characteristics (sugar content and total acids in grape must) of representative genotypes of local varieties Smederevka and Žametovka in production vineyards in the Trstenik wine-growing district. Research results have shown that uvological characteristics of these varieties are slightly better in comparison with previous research carried out in other wine-growing areas, that is, in comparison with general information from literature, which indicates the necessity for further research of these varieties in different agro-eco­logical conditions.
