TOC and CaCO3 content in Oligocene shelf deposits on Lemnos Island and their relation with depositional conditions
Authors: Nioti D. , Maravelis A. , Tserolas P. , Zelilidis A.
Published: January 2017

A series of seventy seven samples from outcrops of mudstones were analyzed in order to evaluate their total organic carbon (TOC) and calcium carbonate (CaCO3) concentrations. Results showed that TOC ranges between 0% to 1.15% (with a mean value of 0.34%) introducing that Oligocene shelf deposits on Lemnos island have fair to good conditions to be potential source rocks. Analysis of CaCO3 presented a range between 1.37% to 42.52% (with a mean value of 16.95%). The comparison of TOC and CaCO3 suggests that the two parameters are either inversely or positively related. The inversely related contents, high TOC and low CaCO3, may indicate anoxic conditions, whereas low TOC and high CaCO3 occur in oxic conditions due to the decomposition of TOC. The CO2 produced by decomposition of organic carbon and production of organic acids reduces the pH in pore water enough to dissolve any CaCO3 that reaches the sediment water interface. On the other hand, a positive relation, with both high TOC-CaCO3 contents, could be related with oxic conditions and high sedimentation rate or incidents of abrupt death and bury of great amounts of benthic organisms (TOC) increasing the maintenance of organic material in the sediment.

Published: January 2017

Urban geochemistry is a fast growing scientific discipline mainly because of the profound impact of large cities on the environment as well as the increase in the world’s urban population. The present study aims to produce the urban geochemical map of Athens, based on multi-element analysis of surface soils (0-10 cm) with emphasis in the spatial distribution of potentially harmful elements (PHEs). Soil sampling was based on a regular 1km x 1km grid, laid over the survey area covering more than 200 km2. Sampling locations within the grid cells were selected giving priority to playgrounds, schools and urban parks. The < 100 μm fraction of a total of 320 soil samples were analysed by Flame Atomic Absorption Spectroscopy for Pb, Zn, Cu, Cd, Cr, Ni, Co and Mn after aqua regia dissolution. Average content of Pb (62 mg/kg), Cu (36 mg/kg), Zn (91 mg/kg) and Mn (465 mg/kg) in soil was lower than reported concentrations from other European cities while Cr (74 mg/kg), Ni (89 mg/kg) and Co (16 mg/kg) were relatively enriched. Geochemical maps were plotted within GIS enabling recognition of spatial trends in elemental concentrations and potential sources of the elements. The research outcome will contribute to the evaluation of quality characteristics of urban soils in Athens and drive attention to areas of any environmental or health risks.

Published: January 2017

In Romania, Maastrichtian (Late Cretaceous) dwarf dinosaur remains were first reported from the Haţeg basin by the Baron Franz Nopcsa, at the end of 19th century. Later, the same expanded his research to others areas of Transylvania, adding new localities with comparable Maastrichtian vertebrate assemblages in Alba and Sălaj Counties. Following Nopcsa, both these regions and topics have not been studied for a long time. In the last decade, new field works succeeded in finding rich and diverse Maastrichtian terrestrial vertebrate fauna in Alba County restricted to a distinct Late Cretaceous sedimentary area (Metaliferi). For these studies, the Şard Formation is of main interest. In this formation, the Maastrichtian is developed in fluvial system environments which are documented by flood plain overbank and channel fill deposits. Besides fishes, amphibians, birds and mammals, the fossils embrace mainly various dinosaurs such as sauropods, hadrosaurs, ornithopods, ankylosaurs, various small-sized theropods, as well as other reptiles as turtles and crocodilians. Often, the remains are fragmentary and dislocated. Besides the Haţeg basin, the Metaliferi area is the second important region documenting the Maastrichtian terrestrial biota in Romania.
COMPARING LIVING AND HOLOCENE COCCOLITHOPHORE ASSEMBLAGES IN THE AEGEAN MARINE ENVIRONMENTS
Authors: Dimiza M. D. , Triantaphyllou M. V.
Published: January 2017

Detailed quantitative analyses of coccolithophores performed on the shallow deposits of the southeastern Aegean region (core NS-14, 505 m depth), evidenced that the distribution of calcare-ous nannoplankton assemblages during the last 13 ka BP reflects paleoenvironmental changes which are directly related to parameters such as temperature, salinity, productivity and nutrient flux in the water column. Analysis enabled the separation of the assemblages in four groups. Group A consists of Emiliania huxleyi and the subtropical species Syracosphaera spp. and Rhabdosphaera clavigera, Group B is composed of Helicospaera spp. and Florisphaera profunda, typical species for high productivity conditions in the middle-lower photic zone, Group C consists of Gephyrocapsa oceanica and Braarudosphaera bigelowii, that characterise low salinity conditions and Group D includes Umbilicosphaera spp. and Calcidiscus spp. which are described as relatively eutrophic species. The Holocene assemblages differ distinctly from the living coccolithophore communities in the coastal ecosystems of the Aegean Sea, where only Group A coccolithophores are thriving in the seasonally controlled marine environment.
AGE DETERMINATION AND PALAEOGEOGRAPHIC RECONSTRUCTION OF DIAPONDIA ISLANDS IN NW GREECE, BASED ON CALCAREOUS NANNOFOSSILS
Authors: Makrodimitras G. , Stoykova K. , Vakalas I. , Zelilidis A.
Published: January 2017

Diapondia islands - Ereikoussa, Othonoi and Mathraki – extended in the north-western area of Greece, are part of the external Ionian zone of the Hellenides. The exposed sedimentary succession of the three islands consists of up to 74m thick submarine fans, interpreted as inner fan deposits. The determination of the sediment ages is based on the study of calcareous nannofossils, which came from almost 63 samples covering geological cross sections across the coast line of the three islands. The recorded nannofossil associations are assigned to the biozones of Martini’s (1971) standard scheme. According to the age determination clastic sedimentation in the studied area started during the Late Oligocene and finished during the Early Miocene time. Moreover, the age determination and in accordance with the previous results, indicate that also the Ionian thrust activity started during Late Oligocene.
TECTONOSEDIMENTARY SIGNIFICANCE OF THE MESSINIA CONGLOMERATES (SW PELOPONNESE, GREECE)
Authors: Pavlopoulos A. , Kamperis E. , Sotiropoulos S. , Triantaphyllou M.
Published: January 2017

The marine fill of the Gavrovo-Tripolis foreland basin in the Messinia area (SW Peloponnese), includes facies and facies associations, deposited by sediment gravity flows in slope and inner fan settings. The above-mentioned gravity-driven sedimentary processes, resulted in the formation of thinning-upward sequences and fining fan facies associations, composed of impressive sheet-conglomerates at the base (Agia Mavra, Agia Varvara and Mali units), presenting mainly normal internal structure, while clay and sand-clay members predominate at the top. These conglomerates advocate a significant sediment supply and extended accommodation space, during periods of dramatic tectonic uplift, associated with the westward propagation of Pindos thrust front. In the prograding fan system, dominate paleo-currents with main flow direction to southwest. The finer fan facies associations show rapid lateral variations, both in lithology and thickness, indicating rapid changes in the inner, incised, part of the foredeep. Nannofossil analyses suggest that the sedimentation took place during Oligocene (NP22 to NP24 biozones). Three NNW-SSE trending thrust fault zones bound the above-mentioned units and they caused an important structural thickening of the fan facies associations. Biostratigraphic analyses date the end of the thrust activity in GavrovoTripolis zone in Late Oligocene (biozone NP24).
GEOMYTHOLOGICAL APPROACH OF ASOPOS RIVER (AEGINA, GREECE)
Authors: Mariolakos I. , Theocharis D.
Published: January 2017

In Greek Mythology rivers are, with some exceptions, Gods and they were “born” by the Titans, Oceanus and Tethys. The River Gods are also considered to have given birth to some Islands. Amongst them Asopos River has the most important position as he is considered to have given birth to Aegina, Salamis, Euboea and some other islands as well. The myth of Asopos River is remarkable because it is a typical case where the physical-geological evolution allows us to explain the myth, and at the same time, the myth lets us to give an explanation about the diachronic route of Asopos riverbed, especially during the crucial period between 18,000 to 6,000 BP. The area, known as Saronic Gulf today, used to partly be land, including a great lake, the Epidaurus Paleolake, until 13,000 BP. Asopos River, nowadays known as “Rema tis Skotinis”, is located on Aegina island. In this paper we are trying to investigate whether Asopos River was flowing either into the Epidaurus Paleolake or into the Saronic Paleogulf.

Published: January 2017

Palaeoclimatic reconstruction in N. Greece has been investigated in this study, using stable isotope analyses and U/Th dating of a speleothem (stalactite) from the cave of Agios Georgios (Kilkis). Sampling sequence was followed in detail in order to obtain high resolution analysis of the proxy. Speleothem δ18O entirely depends on two factors: changes in the δ18O of the percolation waters (a proxy for local rainfall δ18O) and the temperature of water-calcite fractionation inside the cave (a proxy for outside air temperatures). During periods of relatively stable temperatures, δ13C shifts are caused principally by variations in soil CO2 input and physico-chemical processes inside the cave. More important processes affect the δ13C signal of speleothem inside the cave are length of flow path and rates of CO2 degassing.The lower δ13C calcite values indicate greater respiratory activity of soils under wetter conditions. The stalagmite layers were dated through U/Th geochronological method, which places the carbonate precipitation in Middle Pleistocene (630-300ka BP). The isotopic composition of the layers was used in combination with the dating results to reconstruct the evolution of the area of Kilkis. Correlation with global climatic records shows that major climatic transitions that influenced northern hemisphere seem to have also affected the region of N. Greece.
EVALUATING THE INFLUENCE OF GREEK GEOPARKS TO THE LOCAL COMMUNITIES
Authors: Fassoulas C. , Zouros N.
Published: January 2017

The European geoparks are new and effective instruments for the interpretation, protection and promotion of geological heritage aiming to a sustainable local development. Since 2000 the two Greek geoparks, the Lesvos Petrified Forest and the Psiloritis Natural Park have developed a great number of activities. Because of their differences, these two geoparks can be used as good examples to evaluate contribution of geoparks to local economy. In Psiloritis geopark operation is supported by the AKOMM –Psiloritis SA Development Company and significant funds have been raised for geo-protection and geo-tourism through European projects, a certain operational budget from local funds has been established and a new action plan has been developed under the forthcoming Leader+ project. In Lesvos Petrified Forest geopark operation is supported by the Natural History Museum of the Lesvos Petrified Forest which is responsible for research activities, protection and promotion of this protected natural monument. Main activities were funded by the North Aegean Regional Operational Framework as well as by INTERREG and LEADER initiatives to promote geoconservation, geotourism and local development. Furthermore, in both areas exchange of know how and best practices assisted local stakeholders and staff of local authorities to develop skills on the nature protection and promotion of geoheritage. Additionally, a great number of publications, environmental education programs and promotional activities contributed to the information and education of local communities, as well as of visitors on their geological and natural heritage. All the above mentioned activities have significant impact in local economy through the development of geotourism.

BUILDINGS’ DAMAGE AT HOREMI VILLAGE, ARKADIA, GREECE: EVALUATION OF THE GEOTECHNICAL CONDITIONS AT SHALLOW DEPTHS
Authors: Kynigalaki M. Kynigalaki M. , Kanaris D. , Nikolaou N. , Kontogianni V.
Published: January 2017

Horemi village is located in Central Peloponnesus, at the western margins of Megalopoli basin. For several years failure phenomena on the village buildings have been reported, causing problems related both to the safety of the inhabitants, as well as to the development of the area. For the above reasons a geotechnical investigation program was carried out, to study the origin of the failures and lead to certain conclusions for the mitigation of the phenomena. In situ exploratory works, with reference to the investigation of litho-stratigraphy, ground foundation conditions, as well as laboratory testing, provided the necessary data for further research testing of the soil physical and mechanical parameters. Building failure recording, trial pits description, sample collection and laboratory testing, pointed out that failure phenomena are due to geotechnical rather than geological effects. The detection of a clayey horizon, presenting high to very high plasticity and swelling behavior, related to the significant montmorillonite proportion in the surface or shallow geological formations, showed good correlation to building damages. The aforementioned observations are considered to clarify the case presented in this paper.
GEOLOGICAL BEHAVIOUR OF ROCK MASSES IN UNDERGROUND EXCAVATIONS
Authors: Marinos P. V
Published: January 2017

The paper deals with the engineering geological behaviour of rock masses in underground excavations. In general, the application of the well-known classification systems has the drawback of not displaying necessary information concerning the behaviour of rock masses, especially the weak ones, in tunnelling. Consequently, there are many cases in which the geological “identity” of the geomaterial is lost since it is not involved in the analysis. In that way it is possible that its special characteristics are mislaid. Within this framework, a system for assessing the failure type mechanisms of the rockmass (i.e. deformation due to overstressing, overbrakes or wedge failure, “chimney” type failure, ravelling ground) for unsupported tunnel-section is presented. These parameters, used for this system, are the structure of the rockmass, the intact rock strength and the overburden thickness. The experience gained by the recent tunnelling construction in the Greek territory, under particularly difficult geological conditions, provided excellent and numerous data for this study.

Published: January 2017

On July 18, 2009, an important landslide occurred in Nachterstedt City toward to the artificial Concordia Lake, which was created, in 1994, at the place of an old coal mine, at the edge of the city. The area is located to North-East of Harz, between the cities of Aschersleben and Quedlingburg. An underground coal mine is responsible for this damage which caused the damage of a privet house and a big building. Three people were also died. The mine apparently closed in 1991 whereupon it was converted into a recreation area. The landslide was caused by the increase of the groundwater level, in the coal mine, after a heavy rain, in relation to the water level of the lake.
RADON: GEOINFORMATION FOR THE PLANNING OF URBAN – SUBURBAN REGIONS. THE CASE OF NAFPLION CITY, GREECE
Authors: Koukoulis A. , Karageorgiou D.E.
Published: January 2017

Radon is trapped in the terrestrial cover as a transmutation product of natural radioactive elements. It is directly related to the geotectonic environment and the atmosphere contains traces of radon near the ground, as a result of emanations from soil and rocks, both of which contain minute quantities of radium; it also infiltrates into the ground and circulates in groundwater. Because naturally occurring radon gas has come to be recognised as a potentially serious health hazard, especially in the built environment, a radon and radiometric (α- and γ-radiation) survey was carried out in the urban and suburban region of Nafplion, using the same grid of 500 x 500 m that was used by other methods, i.e., urban geochemical and geophysical surveys. Radon was measured down to a soil depth of 50 cm, and at each site α- and γ-radiation measurements were taken. The survey results have shown that these concentrations are low compared to other regions of Greece. However, potential accumulations of radon in closed underground spaces cannot be excluded. The isoradon contours of these concentrations form anisotropy axes of main NW to NE and N-S direction related to geological-tectonic structures.

Published: January 2017

The need to provide data management capabilities in geotechnical projects, makes data visualization in a more understanding way vital, while improvements in computer science, have created an opportunity to rethink the manner in which such data is archived and presented. Geographic Information Systems are considered nowadays as principal methods for analysis, utilizing their ability of manipulating, compiling and processing spatial data, such as geotechnical one. In this paper, the development of Borehole Analysis System (BAS) a specific Graphical User Interface (GUI) application is proposed to access geotechnical data with the aim of a relational database and an open source GIS platform, embodied in the application. The BAS, is able to integrate multiple layers of gathered information and to derive additional knowledge by applying statistical and data mining algorithms with the use of spatial query tools. These can give reasonable conclusions and better representation in 2-D and 3-D environment. The presented application is illustrated with an example from field practice, testifying its ability to be a useful tool for management and presentation of geological and geotechnical borehole data.
GEOPHYSICAL RESEARCH FOR GEOLOGICAL STRUCTURE DETERMINATION IN THE REGION OF SOUTH MESOGHEIA (ATTICA)
Authors: Alexopoulos J.D. , Dilalos S.
Published: January 2017

During the last years the broader area of Koropi (Mesogheia-Greece), has faced rapidly increasing problems concerning irrigation and watering of the town, due to the brackish water in the water supply boreholes. Our main target is to determinate the subsurface geological structure of the study area, located NE of the Koropi city, where alterations of schists and carbonates, from three different post-alpine units, mainly appear and relate it with the groundwater flow paths. The dominant geological outcrops of the area are the Athenian Schist (Laurion-Attica Unit), the dolomitic marbles (Vari-Kirou Pira Unit) and the Lower Marble (Hymittos Unit). A geophysical research was carried out in the area mainly based on the geoelectrical methodology, including by executing fifteen Vertical Electrical Soundings and one Electrical Resistivity Tomography. The interpretation results of the geophysical data have been evaluated and combined with “in-situ” resistivity measurements and calibrated with cores coming from drilled boreholes revealing the area. Through this combining process important elements of the local geological subsurface structure have been determined, as the formation of the dolomitic marbles (massive or karstified) was found tilting southwards beneath the Athenian Schist. From a hydrogeological point of view, this alone adds a significant parameter to the subsurface geological structure which is highly related to the groundwater flow that is responsible for many problems and could be used for solving many others.
CONTRIBUTION OF GEOPHYSICAL METHODS TO THE INVESTIGATION OF GEOTHERMAL CONDITIONS IN THE SOUTHWESTERN PART OF THE STRYMON BASIN (MACEDONIA, NORTHERN GREECE)
Authors: Arvanitis A.A. , Stampolidis A.D. , Tsokas G.N.
Published: January 2017

The Strymon basin is one of the most important sedimentary basins in Northern Greece where significant geothermal fields are located. The SW part of the Strymon basin manifests geothermal interest. Available geophysical data (seismic, gravity, magnetic and electrical data) contributed to the identification of major faults that control the fluid-flow paths of the geothermal field and the estimation of depth to the metamorphic basement. The former is of great importance because the geothermal aquifer is expected to be at the contact of the basal conglomerate with the metamorphic basement. The highest thermal gradient values (10-15o C/100 m) were observed in the western part of the study area near the known geothermal field of Therma – Nigrita. Other important geothermal anomalies (>6o C/100 m) occur in the Patriki area, north of the village of Ivira and in the area between the villages of Patriki and Achinos. Geothermal interest manifests itself in the following areas: north of Mavrothalassa (>4o C/100 m), southwest of Ivira and east of Agios Dimitrios. It appears furthermore that the main thermal anomaly is associated with two NW-SE fault systems that affect the basement in the areas of Patriki and north of Achinos - Ivira correspondingly. These faults have been detected by the use of geophysical surveys. The presence of NE-SW faults extends the anomaly southwestwards.
LARGE SCALE VERTICAL ELECTRICAL SOUNDINGS SURVEY IN ANTHEMOUNTAS RIVER BASIN FOR EVALUATING HYDRAULIC COMMUNICATION BETWEEN SUB BASIN AQUIFERS
Authors: Vargemezis G. , Fikos I.
Published: January 2017

In Anthemountas river basin a number of studies have taken place mainly because of the significant drop of underground water level observed in the beginning of the last decade. Data from existing hydrowells show the existence of a complex aquifer with the two main underground water bodies situated east and west of the region of Vasilika and Galarinos villages respectively. A large scale geophysical survey took place consisting of Vertical Electrical Soundings (VES) and Electrical Resistivity Tomography (ERT). The main area of interest is in the central region of the basin between Vasilika and Galarinos villages where eighty five (85) VES (Schlumberger array), located on a regular grid revealed a three dimensional model for the sedimentary formations while mapping the bedrock down to a depth of more than 600m has been achieved. In the same area, ERT measurements and geological information derived from borehole data are used to obtain a more detailed geological model for the area of interest. From surface to bedrock depth, the hydraulic communication between these two water bodies is examined. Furthermore significant geological features are observed and discussed.
CONTRIBUTION OF DEEP ELECTRICAL RESISTIVITY TOMOGRAPHY TECHNIQUE TO HYDROGEOLOGICAL STUDIES: CASES FROM AREAS IN KAVALA (NORTH GREECE)
Authors: Vargemezis G. , Tsourlos P. , Mertzanides I.
Published: January 2017

The most common geophysical method widely used in hydrogeological surveys concerning deep investigations (150-300m of depth) is the resistivity method and particularly the Vertical Electric Sounding (VES) using the Schlumberger array. VES interpretations assume 1D geoelectrical structure yet it is obvious that such an interpretation assumption is not valid in many cases where 2D and 3D geological features exist. In such cases the application of geoelectrical techniques which can provide both vertical and lateral information concerning the resistivity variations is required. Techniques such as the electrical resistivity tomography, mostly used for the 2D and 3D geoelectrical mapping of near surface applications can be adapted to be used for larger investigation depths provided that modified equipment (viz. cables) is used. In the present paper, the application of deep electrical resistivity tomography (ERT) techniques is applied. ERT array of 21 electrodes, at a distance of 50 meters between them (total length 1000 meters) has been used in several studied areas located in the prefecture of Kavala (North Greece). In several cases near surface structure has been compared with VLF data. The aim of the survey was to study in detail the geological-hydrogeological structure the area of interest in order to suggest the best location for the construction of hydrowells with the most promising results. The 2D images of the geological structure down to the depth of at least 200 meters allowed the better understanding of the behaviour of layered geological formations, since in several cases resistivity values have been calibrated with data from pre-existing boreholes.
MOMENT TENSOR DETERMINATION USING A NEW WAVEFORM INVERSION TECHNIQUE
Authors: Moshou A. , Papadimitriou P. , Makropoulos K.
Published: January 2017

In this study a new waveform inversion methodology was developed to determine the source parameters of an earthquake. This technique is based on analyzing data recorded both at teleseismic and regional distances. To apply the inversion three different methods, which are the normal equations, the QR-decomposition and the singular value decomposition (SVD), were successfully tested, similar results were obtained and the SVD method was selected. The proposed inversion methodology was applied to large, as well as to earthquakes of moderate magnitude. Analysis of moderate events is crucial for seismogenic volumes, where an important number of such earthquakes occur which allow the calculation of their source parameters. Thus, the seismotectonic characteristics of the study area can be determined. The proposed methodology is successfully applied to events located in Greece and its surrounding regions in near real time.
INCORPORATING DIFFERENT SOURCE RUPTURE CHARACTERISTICS INTO SIMULATIONS OF STRONG GROUND MOTION FROM THE 1867, M7.0 EARTHQUAKE ON THE ISLAND OF LESVOS (NE AEGEAN SEA, GREECE)
Authors: Roumelioti Z. , Kiratzi A.
Published: January 2017

We apply the stochastic method for finite-faults (Beresnev and Atkinson, 1997, 1998) to simulate strong ground motion acceleration from the 1867 earthquake that devastated the Island of Lesvos in NE Aegean Sea. Recent geological data are taken into account to construct realistic models of the earthquake source, while a first-order approximation of the site effect variation throughout the entire island of Lesvos is achieved following an empirical approach suggested by Wald and Allen (2007). We test several source models including different segments of the Agia Paraskevi fault, which is most probably the seismogenic fault of the 1867 earthquake. Stronger ground motion is predicted in the central part of the island, i.e. around the assumed seismogenic structure. A significant site effect is evident along the eastern coast of Lesvos, where the capital of Mytilene lies, strongly hit by the 1867 earthquake, and around the gulfs of Kalloni and Geras in the south and southeast parts of the island. Synthetic peak ground acceleration values are converted to macroseismic intensities through an empirical relation and discussed in comparison with available reports on the macroseismic effects of the 1867 earthquake.

Authors: Spiridopoulou Marie
Published: January 2017

Μία από τις πιο σημαντικές μοντέρνες σημασιολογικές θεωρίες περί μεταφοράς ταυτίζει τη μεταφορά με την παρομοίωση. Η εν λόγω αντίληψη βασίζεται εν γένει στο κριτήριο της ομοιότητας και της αντικειμενικής αναλογίας μεταξύ κυριολεκτικού και μεταφορικού και υπακούει στις επιταγές της αποκωδικοποίησης του μεταφορικού νοήματος μ' ένα κυριολεκτικό ισοδύναμο του. Σκοπός του άρθρου είναι να καταδείξει το μη λειτουργικό χαρακτήρα της στις τολμηρές μεταφορές του σουρεαλισμού, τις δομικές διαφορές μεταξύ μεταφοράς και παρομοίωσης και την ανάγκη μιας διαφορετικής προσέγγισης της σουρεαλιστικής μεταφοράς, η οποία θα λαμβάνει υπόψη τη ρηματική έκφραση και τη γλωσσική δομή της, θεωρώντας την πρώτα απ' όλα ως γλωσσικό φαινόμενο. Στη συνέχεια με βάση το corpus των ποιητικών μεταφορών του Μπρετόν και του Ελουάρ, το οποίο απαρτίζεται από τις συλλογές της περιόδου 1924-1934, αναλύεται ο ονοματικός τύπος της γενικής και παρουσιάζονται τα χαρακτηριστικά και τα είδη της. Διαπιστώνεται ο ενιαίος χαρακτήρας του περιεχομένου και των τριών ειδών του τύπου της γενικής, ο οποίος βασίζεται στη σχέση της «ταυτοποίησης» ανάμεσα στους δύο όρους/ουσιαστικά. Η εν λόγω ισοδυναμία και ταύτιση των δύο ονοματικών όρων καταργεί τις έννοιες του μεταφορικού και κυριολεκτικού, του ανόμοιου και του οικείου μέσα από μία συνεχή μετάλλαξη της ταυτότητας τους. Συνεπώς, η σουρεαλιστική ονοματική μεταφορά με γενική δε λειτουργεί ούτε ως συντμημένη παρομοίωση ούτε ως παράβαση κάποιας νόρμας (écart/norme). Πρόκειται μάλλον για μία αντι-μεταφορά, όπου το μόνο trasferì που λαμβάνει χώρα είναι από το υλικό του υποσυνείδητου στη ρηματοποιημένη μορφή του.

Το χειρόγραφο γαλλο-ελληνικό λεξικό του Jules David είναι αποτέλεσμα της μακροχρόνιας και συστηματικής ενασχόλησης του Γάλλου λογίου με την ελληνική γλώσσα, που καλλιέργησε τόσο μέσα από τα αρχαία κείμενα όσο και κατά την παραμονή του στην Ελλάδα, ως καθηγητής της γαλλικής γλώσσας από το 1816 έως το 1820. Καθηγητής πλέον στην έδρα της ελληνικής φιλολογίας του Πανεπιστημίου των Παρισίων, ο David ολοκληρώνει το έργο του και, επηρεασμένος από τις επαφές του με τον κύκλο των Ελλήνων λογίων στο Παρίσι, ενστερνίζεται το αίτημα της ελληνικής λογιοσύνης και ιδιαίτερα του Κοραή για την καλλιέργεια μιας γλώσσας ικανής να ανταποκριθεί στις συγχρονικές εκφραστικές ανάγκες. Συντεταγμένο με βάση το Λεξικό της Γαλλικής Ακαδημίας, το λεξικό του David αποτυπώνει την ιστορική συνέχεια της ελληνικής γλώσσας, από την αρχαία ως τη λόγια γλώσσα της εποχής και τη νεοελληνική κοινή μέσα από μια διαχρονική προσέγγιση των λέξεων. Εκεί όπου δεν υπάρχουν αντίστοιχοι όροι δίνει περιγραφική ερμηνεία, ενώ σε ορισμένες περιπτώσεις προχωρεί στη δημιουργία σύνθετων λέξεων που θα μπορούσαν να ερμηνεύσουν τους αντίστοιχους ξένους όρους. Το γαλλο-ελληνικό λεξικό του Jules David εκφράζει την ιδεολογική θεώρηση της γλώσσας όπως καλλιεργήθηκε στο πλαίσιο του Διαφωτισμού.

Tweeting as a Marketing Tool: A Field Experiment in the TV Industry
Authors: Gong Shiyang , Zhang Juanjuan , Zhao Ping , Jiang Xuping
Published: January 2017

Many businesses today have adopted tweeting as a new form of product marketing. However, whether and how tweeting affects product demand remains inconclusive. The authors explore this question using a randomized field experiment on Sina Weibo, the top tweeting website in China. The authors collaborate with a major global media company and examine how the viewing of its TV shows is affected by (1) the media company's tweets about its shows, and (2) recruited Weibo influentials’ retweets of the company tweets. The authors find that both company tweets and influential retweets increase show viewing, but in different ways. Company tweets directly boost viewing, whereas influential retweets increase viewing if the show tweet is informative. Meanwhile, influential retweets are more effective than company tweets in bringing new Weibo followers to the company, which indirectly increases viewing. The authors discuss recommendations on how to manage tweeting as a marketing tool.
Recycling of Rare Earth Elements
Authors: Lorenz Tom , Bertau Martin
Published: January 2017

Any development of an effective process for rare earth (RE) recycling has become more and more challenging, especially in recent years. Since 2011, when commodity prices of REs had met their all-time maximum, prices have dropped rapidly by more than 90 %. An economic process able to offset these fluctuations has to take unconventional methods into account beside well-known strategies like acid/basic leaching or solvent extraction. The solid-state chlorination provides such an unconventional method for mobilizing RE elements from waste streams. Instead of hydrochloric acid this kind of chlorination decomposes NH4Cl thermally to release up to 400 °C hot HCl gas. After cooling the resulting solid metal chlorides may be easily dissolved in pH-adjusted water. Without producing strongly acidic wastes and with NH4Cl as cheap source for hydrogen chloride, solid-state chlorination provides various advantages in terms of costs and disposal. In the course of the SepSELSA project this method was examined, adjusted and optimized for RE recycling from fluorescent lamp scraps as well as Fe14Nd2B magnets. Thereby many surprising influences and trends required various analytic methods to examine the reasons and special mechanisms behind them.

Authors: Segawa Yasutomo , Yagi Akiko , Itami Kenichiro
Published: January 2017

Cycloparaphenylenes and analogues thereof are substances having excellent structural and electronic properties due to radial π-conjugation modes and porous structures. Since they are partial structures of carbon nanotubes, they have also attracted attention as a template for carbon nanotube synthesis. In this chapter, we introduce a series of research on the synthesis of cycloparaphenylenes and their analogues.
The Political Economy of Prison Labour: From Penal Welfarism to the Penal State
Authors: Scherrer Christoph , Shah Anil
Published: January 2017

The article traces the return of prison labour for commercial purposes in the United States. In the age of Fordism, work for commercial purposes was prohibited in prisons; the emphasis was on rehabilitation. This “penal welfarism” gave way to a “penal state” of extremely high incarceration rates and exploitative prison labour. While this shift mirrors the turn to neo-liberalism, it is also the result of specific labour market conditions and racial discrimination.

Objective

The hypothalamus–pituitary–thyroid (HPT) axis set point develops during the fetal period and first two years of life. We hypothesized that thyroxine treatment during these first two years, in the context of a randomized controlled trial (RCT) in children with Down syndrome, may have influenced the HPT axis set point and may also have influenced the development of Down syndrome-associated autoimmune thyroiditis.

Methods

We included 123 children with Down syndrome 8.7 years after the end of an RCT comparing thyroxine treatment vs placebo and performed thyroid function tests and thyroid ultrasound. We analyzed TSH and FT4 concentrations in the subgroup of 71 children who were currently not on thyroid medication and had no evidence of autoimmune thyroiditis.

Results

TSH concentrations did not differ, but FT4 was significantly higher in the thyroxine-treated group than that in the placebo group (14.1 vs 13.0 pmol/L; P = 0.02). There was an increase in anti-TPO positivity, from 1% at age 12 months to 6% at age 24 months and 25% at age 10.7 years with a greater percentage of children with anti-TPO positivity in the placebo group (32%) compared with the thyroxine-treated group (18.5%) (P = 0.12). Thyroid volume at age 10.7 years (mean: 3.4 mL; range: 0.5–7.5 mL) was significantly lower (P < 0.01) compared with reference values (5.5 mL; range: 3–9 mL) and was similar in the thyroxine and placebo group.

Conclusion

Thyroxine treatment during the first two years of life led to a mild increase in FT4 almost 9 years later on and may point to an interesting new mechanism influencing the maturing HPT axis set point. Furthermore, there was a trend toward less development of thyroid autoimmunity in the thyroxine treatment group, suggesting a protective effect of the early thyroxine treatment. Lastly, thyroid volume was low possibly reflecting Down-specific thyroid hypoplasia.

Objetivo: determinar si existe diferencia entre el cálculo de la discrepancia oseodentaria de forma ma-nual y utilizando la aplicación iModelanalisys2. Materiales y método: Se conformó una muestra por conveniencia de 120 modelos de estudio pretratamiento de ortodoncia. Se procedió a realizar la me-dición de todos los órganos dentarios tanto de la arcada superior como inferior, así como la longitud total de ambos arcos con un calibrador digital y calculadora. Posteriormente se realizó el calculo de la discrepancia oseodental introduciendo los datos obtenidos en la aplicación iModelAnalysis2, en un Smartphone. Resultados: El promedio de edad de la muestra fue de 17 años. En el maxilar la media de la discrepancia ósea dentaria al calcularlo de forma manual fue de -3.7mm y al calcularla con el progra-ma iModelAnalysis2 el promedio de la discrepancia óseo dentaria fue de -3.22mm. En la mandíbula, la diferencia entre utilizar la aplicación y hacerlo de forma manual presentó una discrepancia de 0.5mm. Al realizar la comparación de los resultados mediante pruebas de t de Student, no se encontraron dife-rencias estadísticamente significativas. Conclusiones: realizar el calculo de la discrepancia osea dentaria en forma manual o utilizando la aplicación para smartphone iModelanalisys2 no alterará el diagnóstico.

Published: January 2017

Objetivo: Estimar la edad de los cráneos con deformación cefálica artificial a través de la obliteración de las suturas craneanas, palatinas y otros indicadores etaria presentes en la cronología de erupción den-taria; estableciendo relación coherente o discrepante entre ellos. Materiales y método: consistió en 18 cráneos precolombinos comprendidos en la clasificación tipológica de Pedro Weiss.La estimación de la edad está fundamentada en la osificación ectocraneal de las suturas del sistema de la caja craneal y lateral anterior de Meindl & Lovejoy, en la obliteración de suturas palatinas por el método de Mann, y en otros indicadores etarios; registrándose los grados de cierre sutural de cada uno de los puntos craneométricos; valorados como: 0=sutura abierta; 1= obliteración mínima; 2= obliteración significativa; 3= obliteración completa. La sumatoria de los valores obtenidos según Meindl & Lovejov o la obliteración de la última sutura palatina según Mann o la erupción cronológica de los dientes constituyen la edad estimada; esta-bleciendo linealmente una relación de coherencia o de discrepancia entre ellos. Resultados: La edad de los cráneos con deformación cefálica artificial estimada por cierre de suturas craneanas según el método de Meindl y Lovejoy19 expreso valores altos respecto a los estimados por el método de Mann en suturas palatinas. De modo que los valores etarios obtenidos por los métodos suturales expresan la edad aparen-te, siendo los craneanos más que los palatinos, probablemente por las influencias ambientales. Las sutu-ras palatinas y la dentición al estar alejados de la acción de los aperos deformadores expresan valores más cercanos al real; sin embrago podrían estar influidos por otros factores (malos hábitos). Conclusiones Los resultados sugieren que los aperos deformadores podrían haber acelerado el proceso de osificación de la bóveda craneal en 5 a 10 años aproximados, incrementándose aún más en 15 ± 5 años adicionales si se consideran indicadores cronológicos de erupción dentaria.
A Genealogy of Moderate Islam: Governmentality and Discourses of Islam in Indonesia’s Foreign Policy
Authors: Umar Ahmad Rizky Mardhatillah
Published: January 2017

This article analyses the political construction of ‘Moderate Islam Discourse’ in contemporary Indonesian Foreign Policy. Since 2004, the Indonesian Ministry of Foreign Affairs has campaigned for ‘Moderate Islam’ as the main image of Indonesian Islam. Within this discourse, Islam is conceived as ‘moderate’ and ‘tolerant’ as well as inherently compatible with democracy. However, in a more critical perspective, ‘Moderate Islam’’ also contains a political and discursive construction. By using a genealogical approach, I argue that the articulation Islam in Indonesia’s foreign policy is influenced by the ideological underpinnings of each political regime as well as the hegemonic discourse operating in international politics. Furthermore, I argue that there have been three discourses of Islam in Indonesia’s foreign policy, as articulated by different political regimes, namely (1) Islam as religious identity; (2) Moderate Islam from below; and (3) Moderate Islam as a part of the Global War on Terror project.DOI: 10.15408/sdi.v23i3.3157
Islamic School and Arab Association: Aḥmad Sūrkatī’s Reformist Thought and Its Influence on the Educational Activities of al-Irshād
Authors: Yamaguchi Motoki
Published: January 2017

Al-Irshād is an organization formed by the Arabs in present-day Indonesia in 1914, which advocates Islamic reform. This article examines its educational activities in the Dutch colonial period, elucidating the thoughts of its founder and leader, Aḥmad Sūrkatī, and the process of the integration of Arabs into the host society. Sūrkatī’s thought is distinguished from other Arab reformists for its emphasis on “egalitarianism” and its lack of a tendency towards Arab nationalism. From early on, he attempted to adapt the al-Irshād schools to the colonial education system in order to attract indigenous (pribumi) students, as well. In the late 1920s, he began to be locally oriented, with a focus territorially limited to Indonesia. The educational activities of al-Irshād in the 1930s also indicated the weakning of Ḥaḍramī/Arab-orientation. By the late 1930s, the opinion of al-Irshād was decisively inclined toward integration within the host society.DOI: 10.15408/sdi.v23i3.3268
