U radu se donose nalazi otkriveni na predjelu Goveja u gradu Visu na istoimenom otoku, čiji karakter i opisani kontekst pronalaska upućuju na zaključak da je riječ o materijalnim ostatcima antičkog ...paljevinskog groba. Među njima se posebno ističe unikatna keramička posuda, u ovom kontekstu korištena kao urna, za koju se prema tipičnom morfološkom modelu skifa s barbottine ukrasom predlaže izradba u nekoj od radionica koje su grupirane unutar klase Pontske sigilate, odnosno u nekom od crnomorskih/istočnomediteranskih proizvodnih središta. Njezina posebnost ogleda se u dodanom elaboriranom reljefu, koji svojim prikazom uvelike podsjeća na ukrasne detalje s drugih uporabnih predmeta – aplike s fulkruma klina – a koji se interpretira kao prikaz Artemide/Dijane. Detaljna analiza i kontekstualizacija ovdje predstavljenih grobnih nalaza produbljuje naše spoznaje o izradi i potražnji stolnog posuđa kasnog 1. odnosno 2. stoljeća te otvara nova pitanja o izgledu i rasprostranjenosti
isejskih pogrebnih krajolika, kao i o specifičnim odlikama isejskog pogrebnog obreda.
With the goals of protecting boiler tubes from hostile surroundings, increasing thermal efficiency, and minimizing time losses from damage, thermal-spray coating methods for high-temperature ...operations were created. Ceramic-metal composite materials (e.g., Cr3C2-NiCr) are well known for protecting components from erosion decay in a high-temperature environment. In this investigation, the high-velocity oxy-fuel (HVOF) thermal-spray technique was employed to successfully deposit several variations of feedstocks containing Cr3C2-NiCr and NiCr powders onto a medium-carbon steel substrate, with and without filtering through a 400-mesh screen. Utilizing X-ray fluorescence (XRF), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD), the microstructure features of the deposited coatings were assessed. The experiment results demonstrate that the crystallite and grain sizes of the deposited coatings can be increased by reducing the powder size through a sifting process using a 400-mesh sieve. This procedure also resulted in a coating with a higher density and lower porosity. Furthermore, new compounds including Cr2O3 and MnCr2O4 were formed in the coating layers as indicated by the XRD spectra. These phenomena are in good agreement with the EDS mapping of Cr and O, which reveals highly similar distributions. Manganese was originally a part of the substrate composition. Manganese could diffuse rapidly across the Cr2O3 layer and form the MnCr2O4 compound, indicating the manganese diffusion from the substrate into the Cr3C2-NiCr coating. The formation of MnCr2O4 can be attributed to the prior emergence of the Cr2O3 compound.
Prispevek prinaša nova spoznanja o poselitvi Komenskega Krasa v starejši železni dobi. Podrobneje so obravnavana tri v arheološki literaturi že znana najdišča, to so Tomaj, Štanjel in Zagrajec, kjer ...so bile v zadnjih desetletjih izvedene arheološke raziskave v povezavi z gradbenimi in kmetijskimi posegi na najdišču. Članek podaja preliminarne ugotovitve teh raziskav in izbor železnodobnega gradiva iz sočasnih gradišč na Komenskem Krasu: z Gradine pri Brestovici in z Debele griže pri Volčjem Gradu.
Neolithic Farming in Central Europe examines the nature of the earliest crop cultivation, a subject that illuminates the lives of Neolithic farming families and the day-to-day reality of the ...transition from hunting and gathering to farming.
Debate surrounding the nature of crop husbandry in Neolithic central Europe has focussed on the permanence of cultivation, its intensity and its seasonality: variables that carry different implications for Neolithic society.
Amy Bogaard reviews the archaeological evidence for four major competing models of Neolithic crop husbandry - shifting cultivation, extensive plough cultivation, floodplain cultivation and intensive garden cultivation - and evaluates charred crop and weed assemblages.
Her conclusions identify the most appropriate model of cultivation, and highlight the consequences of these agricultural practices for our understanding of Neolithic societies in central Europe.
