The Jacobi-orthogonality in indefinite scalar product spaces

We generalize the property of Jacobi-orthogonality to indefinite scalar product spaces. We compare various principles and investigate relations between Osserman, Jacobi-dual, and Jacobi-orthogonal algebraic curvature tensors. We show that every quasi-Clifford tensor is Jacobi-orthogonal. We prove that a Jacobi-diagonalizable Jacobi-orthogonal tensor is Jacobi-dual whenever J_X has no null eigenvectors for all nonnull X. We show that any algebraic curvature tensor of dimension 3 is Jacobi-orthogonal if and only if it is of constant sectional curvature. We prove that every 4-dimensional Jacobi-diagonalizable algebraic curvature tensor is Jacobi-orthogonal if and only if it is Osserman

The end of the regular coin supply in the Croatian part of the Danube limes

This paper analyses, compares and presents numismatic data gathered by examination of Late Roman coin material, from both the display and study collections of the Archaeological Museum in Zagreb, discovered in the area of two Roman castella in the Croatian part of the Danube limes: Teutoburgium (Dalj) and Cornacum (Sotin). This data has been used for constructing the chronology of the coin supply to, and annual coin circulation intensity at, the sites in the set time frame – i.e. from the Valentinian dynasty until the latest late-imperial Roman coin – in order to try to establish the end of the regular coin supply, and thus contribute to better understanding of the socio-economic and administrative changes in the aforesaid area in the late 4th century. All determined coins are catalogued in detail, while data analysis is presented in charts and tables

Antique and Late Antique fibulae, decorative items and certainaccompanying finds from Verušed

The aim of this work is to primarily present fibulae and decorative items, and secondly co-occuring ceramic material, from the Roman settlement strata in Verušed near Osijek. Verušed is a complex archaeological site found in a rescue excavation during construction of Osijek – Beli Manastir highway route. Finds are typologically and chronologically analysed, catalogued by their stratigraphic unit and presented in pictures and/ or plates. Among decorative items, bracelets are divided into a special group due to the amount, whereas ceramic finds are separated into terra sigillata and kitchenware, tableware and storage ware. In attempt to make clearer chronological frame of the settlement, coin finds are also examined and presented. Fibulae, certain decorative items, terra sigillata and coins are used as indicators for chronological attestment of other, chronologically less sensitive, archaeological material that has been found in the same archaeological context

Kasnoantičke fibule i ukrasni predmeti iz Verušeda

Fibule, ukrasni predmeti te popratna keramička građa, pronađeni u slojevima antičkog naselja na arheološkom nalazištu Verušed, datiraju se od 2. do početka 5. stoljeća, s najvećom koncentracijom nalaza iz kasnoantičkog vremena, što potvrđuju i nalazi antičkog novca uglavnom s kraja 3. i iz 4. stoljeća. obzirom na vrstu i dataciju obrađenih stratigrafskih jedinica te tip i kvalitetu nalaza može se zaključiti kako se na arheološkom nalazištu Verušed nalazilo naselju seoskog tipa (vicus), a u kojem je živjelo romansko i romanizirano stanovništvo. Naselje se nalazilo na geostrateškom položaju, u blizini velikih prometnih pravaca, kojima su komunicirali urbani centri u Panoniji i susjednim provincijama. Najraniji predmeti rimske provenijencije datiraju se u 2. stoljeće, a u naselju se živjelo do početka 5. stoljeća kada je prestankom života u većim okolnim urbanim centrima, zbog pljački i provala “barbarskih” grupa te destabilizacije rimskog carstva, zamro i život u ovom naselju

COMPARISON OF THE COMPOSITION OF MEAT OF WILD AND FARMED PHEASANTS

Cilj ovog istraživanja bio je odrediti osnovni kemijski sastav te sastav masnih kiselina prsnog mišića (Musculus pectoralis major) divljih i uzgojenih fazana (Phasianus colchicus sp. L.).Osnovni kemijski sastav nije pokazao statistički značajnu razliku (p>0,05). Prsni mišić fazana sadrži 72% vode, 0,5-0,7% masti, 26% proteina te 1,3 % pepela. Najzastupljenije masne kiseline su oleinska (C18:1), palmitinska (C16:0), linolna (C18:2) i stearinska (C18:0). Usporedbom sastava masnih kiselina uzgojenog i divljeg fazana, udio zasićenih masnih kiselina (SFA) nije se značajno razlikovao, dok je veći udio mononezasićenih masnih kiselina (MUFA), prvenstveno zbog visokog sadržaja oleinske kiseline, imao uzgojeni fazan, a veći udio polinezasićenih masnih kiselina (PUFA) divlji fazan. Omjer n-6/n-3 nije se razlikovao ovisno o uzgoju fazana te je iznosio 4,76 (uzgojeni) i 4,82 (divlji fazan). Zbog visokog sadržaja proteina i niskog sadržaja masti meso fazana nutritivno je vrlo kvalitetno.The aim of this study was to determine the chemical composition and fatty acid composition of the Musculus pectoralis major of wild and farmed pheasants (Phasianus colchicus sp. L.). The chemical composition did not show a statistically significant difference (p>0,05). Pheasant breast muscle contains 72% water, 0,5-0,7% fat, 26% protein and 1,3% ash. The most abundant fatty acids are oleic (C18:1), palmitic (C16:0), linoleic (C18:2) and stearic (C18:0). The content of saturated fatty acids (SFA) did not differ significantly in farmed and wild pheasants, while the increase of monounsaturated fatty acids (MUFA), mainly because of high content of oleic acid, had farmed pheasant. A higher proportion of polyunsaturated fatty acids (PUFA) had wild pheasants. The n-6 /n-3 ratio did not differ regarding of the method of cultivation and was 4,76 in farmed and 4,82 in wild pheasants. Phesant meat is a valuable food product thanks to high protein and low fat content

Bioactive Complexity of the Red Wine “Portugizac”; Is Younger More Beneficial?

The young red wine “Portugizac Mlado vino” is a recognizable and successful local product with Protected Designation of Origin (PDO). This wine is produced of the variety Portugizac mostly, and it is expected to be consumed very soon after the fermentation. The aging of wine allows continuous chemical changes, and the polyphenolic properties are the basic indicator of quality and nutritional value during that process. The objective of this work was to analyze the parameters of polyphenolic quality; total phenols (TP), antioxidant capacity, and stilbene resveratrol and piceid in wine “Portugizac”, related to aging. Special importance is placed on bioactive trans-resveratrol and its corresponding compounds. The nine young wines “Portugizac”, PDO “Plešivica” were analyzed after bottling and after 12 months of bottle storage. An average concentration of TP in young wines Portugizac was 1429.8 mg L-1 (gallic acid), with an average antioxidant capacity (FRAP) of 17.4 mmol L-1 of Fe (II), and an average total stilbene concentration of 7.34 mg L-1. After 12 months of bottle storage at optimal conditions, concentrations of all parameters decreased. An average concentration of TP was 1323.8 mg L-1 , an average antioxidant capacity (FRAP) of 16.0 mmol L-1 of Fe (II), and an average total stilbene content of 7.15 mg L-1. The most interesting bioactive stilbene compound is trans-resveratrol, and its concentration decreased by an average of 60%. It can be concluded that aging affects the content of polyphenols and nutritional complexity and that the consumption of young wine “Portugizac” might be more beneficial
