    Abstract The purpose of the study was to examine the effect of 2 prebiotics and 2 synbiotics on the digestive potency of pancreas in 1-, 3-, 7-, 14-, 21-, and 34-day-old cockerels. Prebiotics (inulin and Bi2 tos) and synbiotics (inulin + Lactococcus lactis subsp. lactis and Bi2 tos + Lactococcus lactis subsp. cremoris) were injected in ovo into the air cell on the 12th d embryonic development. Their application increased the activity of amylase, lipase, and trypsin in the pancreas. The most pronounced changes were observed at the end of the investigated rearing period (d 34). The strongest stimulative effects on amylase were shown by both synbiotics, on lipase synbiotic Bi2 tos + Lactococcus lactis subsp. cremoris, and on trypsin all the used prebiotics and synbiotics. Simultaneously, neither the absolute nor the relative mass of the pancreas in comparison to control group were changed. Also, the injected in ovo compounds did not cause a deterioration in the posthatching condition of the chicken liver, as determined by measurement of the activity of marker enzymes in the blood (alanine aminotransferase and aspartate aminotransferase). Treatment with the prebiotics and synbiotics did not change the feed conversion ratio but Bi2 tos (galacto-oligosaccharide) and inulin (fructan) + Lactococcus lactis subsp. lactis significantly increased final BW

    A Survey of Bayesian Statistical Approaches for Big Data

    The modern era is characterised as an era of information or Big Data. This has motivated a huge literature on new methods for extracting information and insights from these data. A natural question is how these approaches differ from those that were available prior to the advent of Big Data. We present a review of published studies that present Bayesian statistical approaches specifically for Big Data and discuss the reported and perceived benefits of these approaches. We conclude by addressing the question of whether focusing only on improving computational algorithms and infrastructure will be enough to face the challenges of Big Data

    3D VIRTUAL RECONSTRUCTIONS OF MINOAN RURAL SITES: THE CASE OF LIVARI CHEROMYLIA

    The use of 3D sophisticated visualizations and reconstructions is still not common during the process of reconstruction or recreation of the appearance of any preserved architecture of prehistoric (Bronze Age) Crete. However, the author believes that in modern archaeology the use of the up-to-date computer technologies and sophisticated software is necessary. In their opinion, in case of presenting of sites with preserved architecture a creation of ideal 3D reconstruction should become a standard feature of final publications in the near future. The author deals with the study of Minoan architecture, settlement pattern and rural aspect of Minoan Crete in the last years. In this paper, the author – in cooperation with an architect and a specialist in technical modelling – is presenting an ideal 3D virtual reconstruction of the small rural site of Livari Cheromylia (consisting of 4 main structures and several terrace walls), situated on the southern coast in the Bay of Livari, between Goudouras and Aghia Irini. The 3D reconstruction of the individual structures and the site as a whole based on the up-to-date scholarship on Minoan architecture and the actual archaeological/architectural parallels in situ as well as on the iconographical sources, is presented below
