This study aimed to investigate the concentrations of cholesterol and triglycerides in the serum of sheep from the area of Livanjsko Polje and Mount Vlasic. A total of 117 sheep of the breed pramenka were included in the research. The sheep were divided into groups according to the sampling area through different periods (July, August, and September). Using an automatic analyzer (Kodak Ektachem analyzer DT 60 II, DTSC Module, and DTE Module), the concentrations of cholesterol and triglycerides were determined in the serum of sheep. In the area of Livanjsko Polje, the highest established value of cholesterol in sheep serum was in the second sampling period, with statistical significance compared to the other two sampling periods. Cholesterol values in the Vlasic Mountain area were within the physiological range. The highest established triglyceride concentration in the area of Livanjsko Polje was also the second sampling period, with statistical significance (p <0.05) compared to other sampling periods, as well as the same period from the Travnik area. The results of triglycerides in the blood serum of sheep from the Vlasic mountain area show a tendency to decrease in the third sampling period, at the end of the lactation period. These results may be due to the effects of various factors, such as age, gender, health, lactation status, and sheep breed.

The objective of the study was to assess the genetic diversity of the Tornjak shepherd dog by analyzing 10 micro- satellite loci. The dogs were divided into three main groups: Tornjaks from Bosnia and Herzegovina (TBA), Tornjaks from Croatia (THR), and a control group containing four subgroups: German Shepherd (GS), Belgian Shepherd (BS), crossbreeds of Tornjaks and other breeds (MIXT), and various other dog breeds (MIXA). The average number of genotypes (GN) and alleles (AN) was 19.2 and 8.4 (TBA), 8.2 and 5.4 (THR), 7.9 and 5.1 (BS), 4.4 and 3.6 (GS), 7.6 and 5.5 (MIXT), and 8.6 and 6.0 (MIXA), respectively. The average values of observed (HO) and expected heterozy- gosity (HE) were 0.7261 and 0.7392 (TBA); 0.7625 and 0.7139 (THR); 0.6857 and 0.6837 (BS); 0.4900 and 0.4640 (GS); 0.6786 and 0.6760 (MIXT); and 0.7067 and 0.7160 (MIXA), respectively. In the TBA population, “private” alleles were observed at all ten loci. The average overall inbreeding coefficient (F) value between the Tornjak and the control group was 0.0768. The AMOVA test revealed the highest degree of variation within the TBA group (55.43%), while no significant variations were observed in the control subgroup GS. The smallest differentiation for TBA was found with THR at 1.86% used the pairwise FST (pFST). The constructed Neighbor-Joining (NJ) dendrogram shows clear grouping of TBA and THR in comparison to the breeds of the control group. In relation to the data presented, a high level heterogeneity of has been established in the studied Tornjak population (TBA).

: Legal metrology ensures consumer protection from inaccurate measurements by regulating numerous instruments, some under EU harmonized legislation and others governed by national decisions based on the International Organization for Legal Metrology (OIML) recommendations. Verification laboratories produce measurement reports, often in unstructured PDF formats. Exploring and analyzing these reports remains inherently tedious and error-prone due to their format as numerous unstructured PDF files. To address these challenges, we introduce ScaleVis, a system combining standard and specialized visualizations to facilitate the exploration and analysis of measurement data including spatial information relevant to eccentricity measurements. The system incorporates data cleaning to resolve inconsistencies from manual entry and provides insights into measurement trends and deviations. Focusing on non-automatic weighing instruments, we analyze verification results to identify significant deviations in linearity and eccentricity. This study focuses on the analysis of non-automatic weighing instruments from various manufacturers and application domains. Using verification results from competent laboratories, we examine the metrological behavior of these instruments, identifying the ranges of linearity and eccentricities with the largest deviations from prescribed errors. A use case with domain experts underscores ScaleVis’s potential to streamline data analysis in legal metrology, with initial feedback indicating strong utility and effectiveness.

This paper deals with a sensitivity analysis of engineering critical assessment, using a fracture assessment diagram of through-thickens axial flaws on pressure equipment. Basic option calculations are performed per BS 7910, using engineering fracture mechanics principles, followed by the provision of assessment points. For evaluation purposes, arbitrary design properties of pressure equipment and temperature-dependent materials properties were used. Several through-thickness axial flaw sizes were used for critical assessment. Furthermore, the sensitivity of critical assessment is evaluated by varying stress states and material fracture toughness. Finally, the sensitivity analysis shows how axial flaw growth may become critical, or its acceptability, depending on varying stress states and temperature-dependent material properties, on selected pressure equipment.

Introduction: Composite materials may be exposed to chemicals in food and beverages in the oral cavity, which can lead to changes in surface roughness. The aim of this in vitro study was to evaluate the surface roughness of two restorative materials after exposure to coffee and green tea followed by a dental bleaching procedure. Methods: For nanofilled composite and microhybrid composite, 15 samples each were fabricated. Five specimens from each composite were stored in instant coffee and green tea for 4 h a day. After 30 days of immersion, specimens received dental at-home bleaching, using 16% carbamide peroxide (CP), for 7 h a day. The control group was stored in deionized water for 30 days. Surface roughness was determined by profilometry 24 h after polymerization, after 30 days of immersion, and after bleaching. The data were analyzed using a t-test for paired samples and mixed analysis of variance, at a 0.05 significance level. Results: Neither beverages nor CP treatment significantly altered the surface roughness of the composites. There was no difference between the tested composite materials regarding roughness. Conclusion: Surface roughness of the microhybrid and nanohybrid composites was not modified by coffee, green tea, and subsequent whitening treatment.

There is no doubt that milk and dairy products have a high nutritional value. However, their current consumption is increasingly dependent on their dietary and health properties. It is noticeable that in recent years, increasing popularity is given to those dairy products that have a positive effect on the human body. The aim of this study was to determine the fatty acid composition of sheep's milk from the area of Livno and Travnik (Vlašić), with special reference to the content of bioactive fatty acids that have a positive effect on human health. The fatty acid composition of the tested milk samples was specific due to the content of fatty acids which have been proven to have an extremely beneficial effect on human health. Concentrations of most bioactive fatty acids varied between areas, and the differences were statistically significant for arachidonic, eicosapentaenoic, docosahexaenoic, and rumenic. Milk samples from the tested areas had an almost ideal ratio of n-6/n-3 fatty acids, which makes them very favorable foods from a health point of view.
