Protective Structures for the Preservation of Medieval Buildings and their Remains: Case Studies from Monastery Hilandar and Mount Athos

The objective of this study is to establish a methodology for temporary protective structures, that is, the guidelines for planning, design, and implementation of future protective structures. The basic method of this paper was the observation and analyses of temporary protective structures as well as the evaluation of the results achieved in implementation of these rules in completed structures, within the Hilandar Monastery complex on Mount Athos, in Greece. Mount Athos was inscribed on the UNESCO World Heritage List for its cultural and natural values. The Holy Mount Athos is a unique monastic complex in the world and only males are allowed past the entrance. Having performed the evaluation of certain types of temporary protective structures, the given results were offered as recommendation for their design and implementation. The most significant accomplishment of this paper is verification of the designed, calculated, and completed protective structures through practical application within the Hilandar Monastery complex, in accordance with all the factors of site management.     

Re-imagineering Belgrade and Skopje: urban megaprojects between politics and struggle

This comparative study on the urban re-imagineering performed through large-scale urban refurbishment focuses on the specific post-socialist and post-conflict contexts of former Yugoslavia. Through the analysis of legislative and planning documents, expert interviews, reports, and media coverage, this study shows how initiatives for the implementation of grandiloquent urban megaprojects (UMP) in the capital cities of Serbia and Macedonia became extreme examples of national image reconstruction, carried out through autocratic state-led interventions that disregarded public input. The two main insights that the study provides classify these cases as rather particular in the European framework. First, the national governments have played a decisive role in conceiving entrepreneurial strategies for national rebranding through urban re-imagineering of its capital cities. Second, this politically orchestrated processes advanced through non-transparent decision-making, in spite of the rising opposition by the civic alliances. In conclusion, autocratic implementation of UMPs in the urban contexts of the Yugoslavian successor states played out much more forcefully, overriding the imperative to satisfy genuine public interest.     

The first fossil record of Nandeva Wiedenbrug,Reiss & Fittkau (Diptera: Chironomidae) in early Eocene Fushun amber from China

Gi?ka, W., Zakrzewska, M., Baranov, V., Wang, B. &; Stebner, F., May 2016. The first fossil record of Nandeva Wiedenbrug, Reiss &; Fittkau (Diptera: Chironomidae) in early Eocene Fushun amber from China. Alcheringa 40, xxx–xxx. ISSN 0311-5518

The first fossil representative of the extant chironomid genus Nandeva Wiedenbrug, Reiss &; Fittkau, 1998 Wiedenbrug, S., Reiss, F. &; Fittkau, E.J., 1998. Nandeva, gen. nov., a new genus of Chironomini (Insecta, Diptera, Chironomidae). Spixiana 21, 59–68. [Google Scholar] is described based on a specimen found in early Eocene (50–53 Ma) Fushun amber from China. The adult male of Nandeva pudens sp. nov. has the long RM vein as a continuation of M and R₄₊₅, the bare squama, the strongly reduced anal area of the wing and hypopygial characters typical of extant species of the genus. Following the systematic concept based on adult male morphology and characters examinable in fossil specimens, we present N. pudens as a possible member of the Tanytarsini, arguing that Nandeva is part of this tribe or a possible sister group to the tribe. This is the first record of Nandeva from the Palaearctic region.

A new large fossil species of Tiliqua (Squamata; Scincidae) from the Pliocene of the Wellington Caves (New South Wales,Australia)

?erňanský, A. & Hutchinson, M.N., 2012. A new large fossil species of Tiliqua (Squamata; Scincidae) from the Pliocene of the Wellington Caves (New South Wales, Australia). Alcheringa, 1–6. ISSN 0311-5518.

We describe an isolated frontal bone referable to a new species, Tiliqua laticephala (Scincidae), from the Pliocene Big Sink doline of the Wellington Caves, central eastern New South Wales, Australia. The bone is very robust, is unusually broad and thick, especially around the bases of the subolfactory processes and represents a large and heavily built lizard. The fossil has multiple fragmentary osteoderms in the frontal region, showing asymmetry in shape and thickness that do not correspond to the more regularly arranged anterior head shields of other scincoids. The specimen shares two unusual character states with extant Tiliqua, especially the large armoured species, T. rugosa. Other large skinks related to T. rugosa (other Tiliqua spp., Corucia zebrata, Egernia cunninghamii, Bellatorias major, Liopholis kintorei) are less similar in terms of frontal shape, thickness, sculpture, osteoderm ornamentation, and positioning of adjacent bones.     

Mobilization of ore fluids during Alpine metamorphism: evidence from hydrothermal veins in the Variscan basement of Western Carpathians,Slovakia

Hydrothermal polymetallic veins of the Gemeric unit of the Western Carpathians are oriented coherently with the foliation of their low‐grade Variscan basement host. Early siderite precipitated from homogeneous NaCl‐KCl‐CaCl₂‐H₂O brines with minor CO₂, while immiscible gas–brine mixtures are indicative of the superimposed barite, quartz–tourmaline and quartz–sulphide stages. The high‐salinity aqueous fluid (18–35 wt%) found in all mineralization stages corresponds to formation water modified by interaction with crystalline basement rocks at temperatures between 140 and 300°C. High brominity (around 1000 ppm in average) resulted from evaporation and anhydrite precipitation in a Permo‐Triassic marine basin, and from secondary enrichment by dissolution of organic matter in the marine sediments at diagenetic temperatures. Sulphate depletion reflects thermogenic reduction during infiltration of the formation waters into the Variscan crystalline basement. Crystallization temperatures of the siderite fill (140–300°C) and oxygen isotope ratios of the parental fluids (4–10‰) increase towards the centre of the Gemeric cleavage fan, probably as a consequence of decreasing water/rock ratios in rock‐buffered hydrothermal systems operating during the initial stages of vein evolution. In contrast, buoyant gas–water mixtures, variable salinities and strongly fluctuating P–T parameters in the successive mineralization stages reflect transition from a closed to an open hydrothermal system and mixing of fluids from various sources. Depths of burial were 6–14 km (1.7–4.4 kbar, in a predominantly lithostatic fluid regime) during the siderite and barite sub‐stages of the north‐Gemeric veins, and up to 16 km (1.6–4.5 kbar, in a hydrostatic to lithostatic fluid regime) in the quartz–tourmaline stage of the south‐Gemeric veins. The fluid pressure decreased down to approximately 0.6 kbar during crystallization of sulphides. U‐Pb‐Th, ⁴⁰Ar/³⁹Ar and K/Ar geochronology applied to hydrothermal muscovite–phengite and monazite, as well as cleavage phyllosilicates in the adjacent basement rocks and deformed Permian conglomerates corroborated the opening of hydrothermal veins during Lower Cretaceous thrusting and their rejuvenation during Late Cretaceous sinistral transpressive shearing and extension.     

Dating of 4th millennium BC pile-dwellings on Ljubljansko barje,Slovenia

We present absolute dates of seven late Neolithic pile-dwellings on Ljubljansko barje, Slovenia. They were settled from ca. 3600 to 3332 (±10) and from 3160 to 3071 (±14) cal BC, as shown by investigations of wood using dendrochronology and radiocarbon wiggle-matching. We defined eleven periods of intensive tree felling (and building activities) and one major settlement gap (when no trees were felled) from 3332 to 3160 cal BC. A major settlement gap presumably also followed after 3071 cal BC (i.e., after the end date of the investigated sites). Our investigations included over 2500 pieces of wood, mainly from the piles on which the dwellings were built. Among important wooden artefacts were a wheel with axle (one of the oldest preserved wheels in the world) and two dugout canoes, all from the settlement phase from 3160 to 3100 cal BC. As shown by parallel studies, the economy in the sites was characterized by copper metallurgy, skilful wood processing and use, cultivation of domestic plants, gathering of wild plants, animal husbandry, hunting and fishing. The settlements were contemporaneous with a number of sites in the north of the Alps, the younger ones coincided with the lifetime of the Neolithic Iceman (Ötzi). Since Ljubljansko barje has a strategic position at the crossroads between western central and (south) eastern Europe the presented absolute dates provide a basis for their comparison with other dated contemporaneous sites (in the west), to revise the chronology of similar sites in the (south) east (which are not yet exactly dated), and to evaluate their interconnection and roles in cultural development in prehistory.     

Do rural development programmes promote gender equality on farms? The case of Slovenia

The necessity of gender equality in agriculture has been identified as a relevant political issue and incorporated into strategic documents and programmes of the EU. However, until now, not much has been examined about the actual contribution of these policy actions and programmes to the everyday life of farm women; there is a considerable gap in the data about women in farming across Europe, particularly for new member states. The article addresses this issue by focusing on the situation of gender equality on farms in Slovenia. Pertaining to two measures of The Rural Development Programme 2004–2006 – the Setting Up of Young Farmers and the Early Retirement of Farmers – the aim of the analysis is to compare the beneficiaries and non-beneficiaries of these two measures at family farms in terms of their development capacities and their inclination towards gender equality. Results based on the survey data ‘Generations and Gender Relations on Slovenian Farms 2007’ revealed the above-mentioned measures did indeed reach those family farms that showed better development capacities in terms of economic and demographic conditions. However, the farms did not show significant development in terms of gender equality as examined through division of work and decision-making on family farms. The rigidity in gender statuses and roles on family farms is explained and discussed through the issue of unequal access of women to farmland ownership and agricultural education, and through persistently weak institutional support to increase political participation and power for farm women.     

Mitochondrial DNA studies of the Pazyryk people (4th to 3rd centuries BC) from northwestern Mongolia

The discovery and excavations in 2006 by joint Russian–German–Mongolian expeditions of the Pazyryk culture burial sites (4th to 3rd centuries BC, Early Iron Age, the Scythian period) in the Altai mountains of northwestern Mongolia near the Russia border provided new material for studying various aspects of these ancient peoples lives, including human, animal and plant remains. Ice accumulation in the graves preserved the human remains, allowing biological analysis of the samples. We conducted a genetic study based on mitochondrial DNA from remains of three Pazyryk culture representatives to investigate the possible genetic relationships of this Siberian Scythian group with populations of adjacent territories. These data support possible genetic contacts between populations of Altai and other Eurasia regions in the Early Iron Age, and are in good agreement with corresponding archaeological and anthropological data. However, a large-scale study of the Pazyryk population gene pool structure must be performed to further confirm these findings.     

MINERALOGY OF MEDIEVAL SLAGS FROM LEAD AND SILVER SMELTING (BOHUTÍN,PŘÍBRAM DISTRICT,CZECH REPUBLIC): TOWARDS ESTIMATION OF HISTORICAL SMELTING CONDITIONS*

Slags from the Pb/Ag medieval (14th century) smelting plant located at Bohutín, P?íbram district, Czech Republic, were studied from the mineralogical and geochemical points of view. Two types of slags were distinguished: (i) quenched slags formed mainly by Pb‐rich glass and unmelted residual grains of SiO₂ and feldspars, and (ii) crystallized slags mainly composed of Fe‐rich olivine (fayalite) and glass. The mean log viscosity value of the slags calculated for 1200°C was 2.119 Pa s. The morphology of olivine crystals was used to estimate the cooling rates of the melt, for some slags indicating rates > 1450°C/h. The projection of the bulk composition of slags onto the SiO₂–PbO–FeO ternary system was used for rough temperature estimates of slag formation, lying probably between 800 and 1200°C.
