In this note we illustrate the main features and the mechanism of the so-called Plana's calendar, a perpetual calendar covering a period of 4000 years. The amount of information provided by Plana's calendar is not limited to the simple correspondence day of the week - date, but include movable Christian feasts.

Creating of Collection of old scientific instruments of Laboratory for experimental psychology, Faculty of philosophy, University of Belgrade is an attempt to preserve a part of history of science in Serbia. There are around 100 instruments in Collection, which mostly came to Belgrade within German war reparations to Kingdom of Yugoslavia, after the World War I. Most of the instruments were made in workshop of E. Zimmermann, precise mechanic of the first psychology laboratory in the world, founded in 1879 by Wilhelm Wundt in Leipzig. They can be grouped on those aimed for examining visual and auditory perception, memory and learning, kimography and ergography and those designed for investigating emotions. Together with books and journals from 19th and beginning of 20th century, instruments create an ensemble based on which it is possible to reconstruct one psychological laboratory from the very beginning of development this scientific discipline.

We presents the results of a radiocarbon dating campaign performed on organic samples from three important prehistoric sites of the Porto Badisco territory (Apulia-Southern Italy): Grotta dei Cervi, Cunicolo dei Diavoli and the village of Portorusso. The dating of a human jaw from Cunicolo dei Diavoli has confirmed the funeral use of the cavity during the Copper Age. On the other hand, AMS radiocarbon dating of a fragment of charcoal extracted from a jug in Macchia a Mare/Zinzulusa style from the Grotta dei Cervi, made it possible to clarify the long debated chronology of this facies. Radiocarbon results are also presented from the fortified village of Portorusso, dated to the Middle Bronze age (XV-XIV centuries BC).

This work aimed at comprehensively evaluate the potential and effectiveness of natural Deep Eutectic Solvents (DESs) for the extraction of different natural compounds from archaeological samples. We compared the procedure by DESs, which are now emerging as green and sustainable solvents, with the more conventional solvent extraction protocols, which gave measurable yields of lipid extract. The different techniques were applied on the absorbed residues of small samples of a replica pottery vessel after cooking experiments of animal fats. Direct extraction by DES and derivatization proved efficient to obtain enough fatty acids for quantification analysis of absorbed lipid residues by GC-MS. The next step was the application of DES extraction procedure on some archaeological samples previously submitted to conventional extraction methods. GC-MS analyses gave comparable results as regards the amounts and relative proportions of fatty acids identified in the archaeological samples, thus encouraging to further refine in the future the analytical protocol by DES.

Within the framework of the BioMAP Project (BIOcostruzioni Marine in Puglia, - P.O. FESR 2007/2013), new acoustic data were acquired in order to identify and locate Coralligenous Habitats (CHs) along the Apulian continental shelf (South Adriatic Sea – Northern Ionian Sea). The analysis of the multibeam echosounder (MBES) dataset allowed us to identify different morphological expression of CHs. Geomorphometric techniques have been applied on the MBES data in order to (1) figure out relationships between the observed morphologies and the associated habitat distribution and (2) quantify the total volume of selected Coralligenous build-ups. Our results were obtained applying a quantitative analytical approach, focusing on the exploitation of the full potential of seafloor data sets in an objective manner. Our approach can be even used to monitor future changes, from anthropogenic impacts (e.g., bottom trawl damage) to the impacts of global change including ocean warming and acidification that can affect the structural complexity and total volume of carbonate deposits characterising the Mediterranean benthic environment.
