    Numerous objects of gold displaying an impressive variety of types and manufacturing techniques are known from the Late Bronze Age (LBA) contexts of Mycenaean Greece, but very little is known about the origin and processing of gold during the second millennium B.C: . Ancient literature and recent research indicate that northern Greece is probably the richest gold-bearing region in Greece, and yet, very little evidence exists regarding the exploitation of its deposits and the production as well as use of gold in the area during prehistory. The unusual find of a group of small stone crucibles at the prehistoric settlement of Thessaloniki Toumba, one with visible traces of gold melting, proves local production and offers a rare opportunity to examine the process of on-site gold working. Furthermore, the comparison of the chemical composition of prehistoric artefacts from two settlements with those of gold deposits in their immediate areas supports the local extraction of gold and opens up the prospect for some of the Mycenaean gold to have originated in northern Greece. The scarcity of gold items in northern Greek LBA contexts may not represent the actual amount of gold produced and consumed, but could be a result of the local social attitudes towards the circulation and deposition of artefacts from precious metals.

    A brief description of the population characteristics, geographical features, history, current political situation, economy, energy supply, foreign relations of Greece is presented. Greece's population of 9.95 million is 98% Greek, and the official language is Greek. 97% of the population is Greek Orthodox, and 2% is Muslim. Schooling is compulsory for 9 years, and the literacy rate is 89% for women and 96% for men. The infant mortality rate is 13.8, and life expectancy is 72 years for males and 75 years for female. Greece is situated on the southern tip of the Balkan Peninsula and consists of the mainland, the Peleponnesos, and numerous islands including Crete. Most of the land mass is mountainous, large areas are dry, and only 28% of the land is arable. From the earliest time until recently, emigration from Greece to other countries was a common pattern. Since the 1960s, internal migration to urban areas was the dominant migration trend. Currently, 30% of the population lives in Athens. Despite the growing industrialization and urbanization of the population, the Greeks retain many traditional family and social values. Greece was part of the cradle of civilization, and its history is characterized by the rise of the Minoan culture on Crete, the rise and fall of the Myceneans on the Peleponnesos, the development of the city states of Athens and Sparta, the destruction of Athens during the Peloponnesian War, domination by the Macedonians, the creation of the Hellenistic cilivization, conquest by the Roman Empire, the establishment of the Byzantine Empire, and in 1459 conquest by the Ottoman Empire. In the 1820's Greece fought for and finally won its independence, In World War I Greece fought on the side of the Allies. In World War II, the Greeks successfully resisted an invasion from Italy. In 1941, the country was taken over by the Germans, but the Greek resistance movement continued to fight the Germans until liberation. Between 1944-49, there were 2 unsuccessful

    The aim of this paper is to examine how the river flow monitoring consists a tool for hydro-diplomacy. Management of transboundary catchments and the demand of common water resources, often comprise the cause of conflicts and tension threatening the peaceful coexistence of nations. The Water Framework Directive 2000/60/EU sets a base for water management contributing to common approaches, common goals, common principles as well as providing new definitions and measures for Europe's water resources. In northern Greece the main renewable resources are "imported" (over 25% of its water reserves) and for this reason the implementation of continuous flow measurements throughout the year is necessary, even though difficult to achieve. This paper focuses on the three largest transboundary rivers in Northern Greece. Axios and Strymonas river flow across the region of Central Macedonia in Northern Greece. Axios flows from FYROM to Greece, and Strymonas from Bulgaria to Greece. Nestos river flows from Bulgaria to Greece. The Greek part is in the region of Eastern Macedonia and Thrace in Northern Greece. Significant productive agricultural areas around these rivers are irrigated from them so they are very important for the local society. Measurements of the river flow velocity and the flow depth have been made at bridges. The frequency of the measurements is roughly monthly, because it is expected a significant change in the depth flow and discharge. A series of continuously flow measure-ments were performed during 2013 and 2014 using flowmeters (Valeport and OTT type). The cross-section characteristics, the river flow velocity of segments and the mean water flow velocity and discharge total profile were measured and calculated re-spectively. Measurements are conducted in the framework of the national water resources monitoring network, which is realised in compliance to the Water Framework Directive under the supervision and coordination of the Hellenic Ministry for the

  7. A Quantitative Analysis of Rift Processes in the Northern North Sea and Central Greece.

    Actively extending sedimentary basins provide a snapshot of the way in which basins evolve. Our observations from such regions are temporally limited: we have little understanding of the long-term processes involved but an excellent understanding of the short-term motions (100-102 years). The converse is true of tectonically dead basins where the deformation has ceased and only the end product can be observed. Studies of active basin formation in central Greece have provided a quantitative understanding of the kinematics of extensional tectonics. The use of GPS, SAR interferometry and geomorphological analysis has constrained the rate of extension and fault kinematics and geometries. Central Greece has often been cited as a present-day analogue for formation of the now inactive East Shetland Basin (ESB) in the northern North Sea. A large 3D seismic dataset has been compiled giving complete coverage of the ESB, a region comparable in size to central Greece ( ˜10,000 km2). A quantitative comparison between Greece and the ESB will close the gap in knowledge between short-term and long-term motions. Whilst the two regions have many features in common, such as tilted fault blocks, fault segments of comparable length and similar fault geometries, there are also important differences. For example, one difference between Greece and the northern North Sea is the rate of extension. The North Sea had a peak strain rate that was an order of magnitude slower than the rate at which Greece is currently extending across the gulfs of Corinth and Evia. Another difference is that the distance between large active faults in Greece appears to be significantly longer than in the ESB. A specific example of this difference in scale is the Tern-Eider ridge, which is a horst block in the ESB that appears superficially similar to the island of Evia in Greece. However, the rigid island of Evia is significantly wider than the Tern-Eider ridge. A link between this inter-fault distance and

    The Vertiskos Unit of northern Greece is an elongated basement belt with a complex poly-metamorphic history. It extends from Greece (Chalkidiki peninsula), to the south, up to Serbia, in the north, and arguably represents the westernmost part of the Rhodope Metamorphic Province (northern Greece to southern Bulgaria). The Vertiskos Unit experienced a medium pressure lower amphibolite-facies metamorphic overprint during the Alpine Orogeny. The available medium-temperature geochronology implies that it remained at temperature of approximately 300°C (or slightly higher) during Lower Cretaceous. In order to constrain its post-Lower Cretaceous thermal history, until near-surface exposure, we applied apatite fission track analysis. The central ages obtained range from 68.5 ± 3.8 to 46.6 ± 3.6 Ma (uppermost Cretaceous to Middle Eocene) and mean track lengths between 13 and 13.5 µm. We applied two inverse thermal modeling approaches using either each sample independently (high degree of freedom in the thermal history, better data fit) or all samples together interpreting them as a vertical profile (simpler thermal history, worse data fit). Irrespective of the modeling approach, we conclude that the bulk thermal history of the Vertiskos Unit crosses the high-temperature limit of the apatite partial annealing zone by the uppermost Cretaceous and reaches near-surface conditions as early as lower/middle Eocene. These results contrast with the thermal history of the other domains of the Rhodope Metamorphic Province further east (namely the Southern Rhodope Core Complex and the Northern Rhodope Complex) and establish the Vertiskos basement complex as the oldest exhumed coherent basement fragment of the Rhodope Metamorphic Province and Greece.

    Introduction Sexually transmitted diseases (STDs) are a major public health issue in Europe. Numerous outbreaks of syphilis have been described recently and an increased prevalence of high-risk sexual practices has raised concern about the transmission of HIV and other STDs. Similarly, an increase in sexually transmitted infections has been recorded in Northern Greece. Methods This report describes a recent outbreak of syphilis in people living with HIV. The demographic, clinical, and serologic data of HIV patients diagnosed with syphilis were recorded and analyzed. Data on syphilis incidence from the general population was also compared to HIV patients’ data. Results Fifty-eight HIV-patients of the Infectious Diseases Unit of a tertiary hospital (5.2%) were diagnosed with syphilis during a three-year period (2008-2010). Highly active antiretroviral therapy (HAART) and coexistence of other STDs were independent predictors of syphilis (OR: 2.4, 95CI%: 1.26, 4.63, p=0.008; OR: 9.4, 95%CI: 4.49, 19.64, p<0.001, respectively). Origin from a country other than Greece (p=0.005), and homosexual contact (p=0.003), were separate risk factors for syphilis in the general population in the same area. Conclusion Diagnosis of a sexually transmitted disease in an HIV patient is a crucial clinical event that should trigger the clinician’s suspicion for high-risk sexual behavior. Sexual health assessments should be a routine process for HIV patients. PMID:27622160

    A groundwater monitoring and modeling program in two aquifers within the lower Nestos river basin in Northern Greece is presented. A monitoring network of 54 wells was developed in the two study areas, and groundwater level measurements and water quality sample analyses were conducted for a period of 2.5 years, from March 2007 to October 2009. The field data were used for the calibration and verification of the mathematical model MODFLOW in the two aquifers. The validated model was used to examine ten alternative management scenarios regarding groundwater abstraction in the two aquifers. The study showed that MODFLOW, if properly validated, is a useful and flexible tool in groundwater resources management. PMID:22755533

    A total of 281 faecal samples from owned shepherd and hunting dogs were collected in the Serres Prefecture, Northern Greece and were examined for the presence of intestinal parasites. The overall prevalence of parasitism was 26% and the 11 species found were: Toxocara canis (12.8%), Trichuris vulpis (9.6%), Giardia spp. (4.3%), Isospora (Cystoisospora) spp. (3.9%), Ancylostoma/Uncinaria spp. (2.8%), Cryptosporidium spp. (2.8%), Alaria alata (2.5%), Strongyloides stercoralis (1.8%), Angiostrongylus vasorum (1.1%), Toxascaris leonina (0.7%) and Dipylidium caninum (0.3%). The prevalence of T. canis and Isospora (Cystoisospora) spp. was significantly higher in young than in adult dogs (p < 0.05). There was no significant difference in prevalence between genders, except for T. canis, which was more common in male dogs (p < 0.05). PMID:17573197

    A field study on the distribution of phlebotomine sandflies was carried out during summer months of 2009 and 2010 in eight sites in two Ionian islands and in northern Greece. A total of 490 sandflies (74.5% females) were collected. Six species of the Phlebotomus genus and two of the Sergentomyia genus were identified. The species with the widest distribution in the islands were Phlebotomus neglectus (32.8%), Phlebotomus similis (30.3%), Phlebotomus tobbi (16.7%), and P. perfiliewi (15.9%), whereas P. simici (50%), P. neglectus (24.5%), and P. tobbi (9.6%) predominated in the mainland. As most of these species are proven or suspected vectors of human and animal pathogens, prevention measures have to be taken in these areas during the summer months when sandflies are active.

    The present study is a multi-analytical approach on the characterization of several potsherd samples, dated from prehistoric to hellenistic times, from Aiani, ancient Upper Macedonia, northern Greece. In particular, X-ray Diffraction (XRD), X-ray Fluorescence (XRF) and Environmental Scanning Electron Microscopy, coupled with Energy Dispersive X-ray system (ESEM-EDX) were used for the determination of the morphological, chemical and mineralogical characteristics of the potsherds. The preliminary results indicated a rather local provenance of the analyzed ancient pottery samples and a finer texture and thus better ceramic manufacture as getting to hellenistic era. The use of a silicious or calcerous raw material is probably related to the specific utilization of each ceramic vessel in ancient times. The presence of gehlenite or pyroxene minerals in the ceramic matrix indicated higher firing temperatures, while lower temperatures were deduced when finding phylosilicate minerals. The preliminary results of this study do not necessarily imply that all the pottery of this area, belonging to the same chronological type, have similar physicochemical characteristics.

    This study was conducted in order to determine the prevalence of hydatidosis due to Echinococcus granulosus sensu lato and the fertility rate of hydatid cysts in sheep, goats, cattle, and pigs slaughtered at the abattoir of Lagkada, in the Prefecture of Thessaloniki, Northern Greece. Lungs and livers from a total of 294 sheep (31.3% infected), 126 goats (8.7% infected), 372 cattle (4.8% infected), and 641 pigs (1.7% infected) were examined. The number of hydatid cysts found in infected sheep was 657 (58.3% fertile, 12.8% sterile, and 28.9% calcified cysts), in goats 54 (14.8% fertile, 38.9% sterile, and 46.3% calcified cysts), in cattle 108 (24.1% fertile, 50.0% sterile, and 25.9% calcified cysts) and in pigs 47 (10.6% fertile, 55.4% sterile, and 34.0% calcified cysts). Lung infection with hydatid cysts was higher (p<0.05) in sheep, goats, and cattle than in pigs (56.5%, 77.8% and 62.0% vs. 17.0%, respectively); while liver infection was lower (p<0.05) in sheep, goats, and cattle than in pigs (43.5%, 22.2% and 38.0% vs. 83.0%, respectively). Among the 4 species slaughtered for human consumption, sheep exhibited the highest frequency of hydatidosis and the highest proportion of fertile cysts. PMID:27393873

    Waterspouts pose a significant threat for coastal areas, maritime activities and structures and thus their study is essential. They are frequently occurring in the Mediterranean Sea and particularly in the northern coasts. A vulnerable area of waterspout formation is the Ionian Sea according to recent research and especially the water body around Corfu Island, Greece. The Laboratory of Climatology and Atmospheric Environment of the University of Athens has assembled a detailed database of waterspout events, providing additional information such as location and time of these events; valuable information for the methodology followed. In this study, the waterspout data base concerns events from 20 March 2007 to 31 December 2013. Thus, a total of 74 events were recorded and catalogued on 47 days, as there were days with multiple waterspout events. The aim of this study is to investigate the temporal evolution of brightness temperature on tops of waterspout parent clouds that triggered the formation of single or multiple waterspout events, based on the aforementioned database. The cloud top temperature was assessed by using channel at 10.8 μm MSG SEVIRI Level 1.5 Image Data product. The minimum brightness temperature of the cloud top around the waterspout location for four different examined radiuses was estimated during 60 min prior to and after waterspout formation. Results are illustrated in terms of seasonal analysis. During autumn season a decrease of brightness temperature (colder values) was detected at waterspout parent cloud close to waterspout formation.

    The Axios Valley, located in central-northern Greece, is surrounded by complex topography that plays a significant role in the modification of wind flow, both in terms of speed and direction. The characteristic wind regime of this valley is Vardaris, a northwesterly wind that prevails in this region, especially during the cold period of the year. Vardaris is well known for its consistent direction and high intensity, as well as for the effective advection of cold and dry air, often resulting to significant damages in local infrastructures and agriculture. A field campaign under the name AXIOS took place during the period from November 2007 through May 2008 in order to examine this particular wind flow. The analysis of the in situ observational data, which was funded by the research program THESPIA-KRIPIS, showed that topography plays a key role in intensifying Vardaris, generating gusts that approximated 30 m s- 1 during the experimental period. The air temperature and humidity fields were also found to be significantly influenced. In addition to the observational study, an intense Vardaris episode was simulated with the Weather Research and Forecasting (WRF) model at high horizontal resolution. Results revealed that the model was able to reproduce the favorable environmental conditions that lead to Vardaris occurrence, providing a useful insight on the physical mechanisms explaining its structure.

    This study investigates an intense precipitation event and its lightning activity that affected northern Greece and primarily Thessaloniki on 15 July 2014. The precipitation measurement of 98.5 mm in 15 h at the Aristotle University of Thessaloniki set a new absolute record maximum. The thermodynamic analysis indicated that the event took place in an environment that could support deep thunderstorm activity. The development of this intense event was associated with significant low-level convergence and upper-level divergence even before its triggering and a positive vertical gradient of relative vorticity advection. The high resolution (1.667 km × 1.667 km) non-hydrostatic WRF-ARW numerical weather prediction model was used to simulate this intense precipitation event, while the Lightning Potential Index was utilized to calculate the potential for lightning activity. Sensitivity experiments suggested that although the strong synoptic forcing assumed primary role in the occurrence of intense precipitation and lightning activity, their spatiotemporal variability was affected by topography. The application of the very fine resolution topography of NASA Shuttle Radar Topographic Mission improved the simulated precipitation and the calculated lightning potential.

    Background: A Vitamin D Receptor gene (VDR) polymorphism, rs10735810 (Fok1), has been associated in the past with idiopathic short stature (ISS) in a linkage study. We have investigated the association of the same, as well as a different polymorphism in the same gene [rs731236 (Taq1)] with ISS, in an independent study in Greek children. Methods: The VDR rs10735810 (Fok1) and rs731236 (Taq1) polymorphisms were genotyped in a group of ISS children (n= 47) and an age and sex-matched group of normal height children (n= 60) from northern Greece. Genotyping was accomplished through established PCR-RFLP methods. Results: An association trend of rs10735810 with ISS was observed, with the TT (ff) genotype being apparently underrepresented among ISS children compared to controls (p= 0.076; OR= 0.165, 95% CI= 0.025-1.094). Conclusions: The above results, together with recent evidence related to the functionality of the rs10735810 polymorphism, cannot exclude an involvement of VDR in the pathogenesis of ISS.

    Introduction: Cancer patients experience a variety of symptoms that can be physical or psychological. These symptoms may vary in terms of occurrence, severity and distress and can be the result of the illness or the treatment. Purpose: The purpose of this study is to investigate the frequency, severity and distress of symptoms that chemotherapy induces in cancer patients. Material-Method: This study included 200 cancer patients undergoing chemotherapy in a major city of Northern Greece. Data was collected using the Memorial Symptom Assessment Scale and Questionnaire, with demographic and clinical characteristics. Results: The vast majority of those included in the sample were male participants (n=127, 63.5%). Their mean age was 58.95 (SD=9.95, range 29-79). The most prevalent physical symptoms were numbness/tingling in the hands/feet (54%), followed by lack of energy (46%). Feeling nervous (52%) and having trouble sleeping (41%) were the two most common psychological symptoms. Conclusions: The results of this study demonstrate that cancer patients undergoing chemotherapy experience various symptoms in high prevalence, and that they are quite severe. Therefore nurses should take into account these findings and plan appropriate, suitable care plans and interventions in order to alleviate them and improve patients’ quality of life. PMID:26543418

    The activity concentration of 238U and 234U has been determined in groundwater samples of hot springs and deep wells from the region of Northern Greece. The analysis was performed by alpha spectroscopy after pre-concentration and separation of uranium by cation exchange (Chelex 100 resin) and finally its electro-deposition on stainless steel discs. The uranium concentration in deep wells and springs varies strongly between 0.15 and 7.66 μg l-1. Generally the springs present higher uranium concentration than the deep wells, except of the Apol-lonia spring, which has shown the lowest value of 0.15 mg l-1. 238U and 234U activity concentration ranged between 1.8-95.3 mBq l-1 and 1.7-160.1 mBq l-1, respectively. The obtained isotopic ratio 234U/238U varies between 0.95 and 1.74 which means that the two isotopes are not in radioactive equilibrium. The highest 234U/238U activity ratio values correspond to the Langada springs, indicating most probably old-type waters. On the other hand, ground waters from wells with relatively low uranium activity concentration and low 234U/238U isotopic ratios, point to the presence of younger waters with a stronger contribution of a local recharge component to the groundwater.

    The Elevation project, funded by the action "Archimedes III - Funding of research groups in T.E.I.", co-financed by the E.U. (European Social Fund) and national funds under the Operational Program "Education and Lifelong Learning 2007-2013" aims mainly to the validation of the Hellenic vertical datum. This validation is carried out over two areas under study, one in Central and another in Northern Greece. During the first stage of the validation process, satellite-only as well as combined satellite-terrestrial models of the Earth's geopotential are used. GOCE and GRACE satellite information is compared against recently measured GPS/Levelling observations at specific benchmarks of the vertical network in Attiki (Central Greece) and Thessaloniki (Northern Greece). A spectral enhancement approach is followed where, given the GOCE/GRACE GGM truncation degree, EGM2008 is used to fill-in the medium and high-frequency content along with RTM effects for the high and ultra high part. The second stage is based on the localization of possible blunders of the vertical network using the spectral information derived previously. The undoubted accuracy of the contemporary global models at the low frequency band leads to some initial conclusions about the consistency of the Hellenic vertical datum.

    2013-04-01

    Small landslides are very common along the submarine margins, due to steep slopes and continuous material deposition that increment mass instability and supply collapse occurrences, even without earthquake triggering. This kind of events can have relevant consequences when occurring close to the coast, because they are characterized by sudden change of velocity and relevant speed achievement, reflecting into high tsunamigenic potential. This is the case for example of the slide of Rhodes Island (Greece), named Northern Rhodes Slide (NRS), where unusual 3-4 m waves were registered on 24 March 2002, provoking some damage in the coastal stretch of the city of Rhodes (Papadopoulos et al., 2007). The event was not associated with earthquake occurrence, and eyewitnesses supported the hypothesis of a non-seismic source for the tsunami, placed 1 km offshore. Subsequent marine geophysical surveys (Sakellariou et al., 2002) evidenced the presence of several detachment niches at about 300-400 m depth along the northern steep slope, one of which can be considered responsible of the observed tsunami, fitting with the previously mentioned supposition. In this work, that is carried out in the frame of the European funded project NearToWarn, we evaluated the tsunami effects due to the NRS by means of numerical modelling: after having reconstructed the sliding body basing on morphological assumptions (obtaining an esteemed volume of 33 million m3), we simulated the sliding motion through the in-house built code UBO-BLOCK1, adopting a Lagrangian approach and splitting the sliding mass into a "chain" of interacting blocks. This provides the complete dynamics of the landslide, including the shape changes that relevantly influence the tsunami generation. After the application of an intermediate code, accounting for the slide impulse filtering through the water depth, the tsunami propagation in the sea around the island of Rhodes and up to near coasts of Turkey was simulated via the

    Seven core samples (five lignite samples and two intraseam nonlignite rock samples) from the Achlada open-cut mine in northern Greece were characterized by X-ray diffraction (XRD) and X-ray fluorescence (XRF) techniques. Quantitative evaluation of the mineral phases in each sample was made from the powder X-ray diffractograms using Siroquant commercial interpretation software, which is based on Rietveld principles. The main minerals in the low-temperature ash (LTA) ash of the lignites are kaolinite and illite, with bassanite and quartz in minor proportions. The nonlignite rock samples mainly consist of illite, mica (2M1), and kaolinite (poorly ordered), along with quartz, chlorite (ferroan), feldspar (albite), rutile, and dolomite. Oriented-aggregate XRD study further shows the presence of smectite, and interstratified illite/smectite (I/S), in the clay fractions of the lignite and rock samples, with the mineral matter of the lignites being richer in kaolinite, smectite, and I/S than in mineral matter of the nonlignite materials. The differences in mineralogy between the lignite and the rock materials probably reflect selective concentration of minerals in the original peat during deposition, combined with authigenic precipitation of minerals such as kaolinite in the peat deposit. Inferred chemical analyses derived from the XRD data show reasonably good correlations with chemical data obtained by direct ash analysis, especially if the smectite and I/S are taken into account. This provides a link between mineralogical and chemical studies that may be valuable in evaluating the behavior of the lignite under different utilization conditions. 27 refs., 4 figs., 6 tabs.

    The Circum-Rhodope Belt (CRB) sensu stricto comprises low-grade metamorphosed Triassic and Jurassic sedimentary rocks fringing the high-grade metamorphic rocks of the Serbo-Macedonian and Rhodope massifs in northern Greece. Main outcrops occur in the easternmost part of the Vardar suture zone in the Chalkidiki peninsula (Melissochori Formation; formerly Svoula flysch) and in Thrace (Makri unit and Melia Formation). The tectonostratigraphic relationship between the CRB and the high-grade metamorphics has been the subject of long discussions. Older interpretations maintain that the CRB represents the original Mesozoic stratigraphic cover of the Serbo-Macedonian crystalline basement, whereas later revisions propose the existence of two distinct greenschist-facies Mesozoic metasedimentary units: an eastern unit related to the development of a Jurassic black shale basin north of the Rhodope, and a western unit related to the development of an olistostromic flysch in the Cretaceous. Here we present a critical re-evaluation of the CRB with regard to its age, provenance, and tectonic setting based on novel geochemical and isotopic data. The Makri unit and the Melissochori Formation belong to the CRB proper and were deposited in proximity to Carboniferous-Early Permian igneous basement rocks (Pelagonia / Strandja / Thracia Terrane) in latest Triassic and Jurassic times, as shown by a prominent detrital zircon age population of 350-290 Ma. By contrast, the Melia Formation is unrelated to the CRB and was deposited in a foreland basin in front of a metamorphic nappe pile with Rhodopean affinities in the early Cretaceous, as shown by a prominent detrital zircon age population of 315-285 Ma and xenocrysts of ~ 550 Ma and ~ 450 Ma. Thus, the commonly accepted CRB concepts have to be revisited. All units have been tectonically juxtaposed to their present location during Balkan and Alpine orogenic processes.

    In the northern part of Greece, close to the city of Kavala, a phosphoric acid production industry has operated since 1965. The raw material used is the phosphate rock imported from the foreign countries. During industrial processes, naturally occurring radioactive materials (NORM) deposits exist in many facilities in the industry, causing increased levels of radiation exposure. Additionally, increased levels of NORM concentrations are also detected in the waste material of the production process, the phosphogypsum. According to the Greek Regulations for Radiation Protection (no. 216B, 5/3/2001), which is in accordance with the 96/29/EURATOM 31/5/1996, the action levels concerning the effective dose to workers at workplaces due to natural radiation sources are 1 mSv y(-1). Work activities where the corresponding doses exceed 6 mSv y(-1) are under the control of the Greek Atomic Energy Commission (GAEC). The mean yearly radon concentration action level at workplaces is 400 Bq m(-3), while the corresponding concentration limit is 3000 Bq m(-3), respectively. GAEC, according to its constitutional law, is the responsible organisation to enforce and to implement the law by means of in situ surveys and laboratory measurements. The first inspection of the area was performed in 2002 and the first measures were proposed. Periodic inspections were performed every 2 y in order to extend the operation licensing of the industry. In this work a dose assessment of the workers based on in situ and laboratory measurements is presented. In order to assess the doses to the workers the external and the internal doses are estimated.

    A VAN-prediction was announced on January 6, 1991, through the French newspaper “Le Monde” and on January 8-10, 1991, through Greek newspapers and TV stations. We evaluate this prediction on the basis of a letter which was sent by Prof. Varotsos (without date) to the Greek Minister of Public Works, and by considering previous VAN-publications as well as recent seismological data for the candidate regions. We conclude that what was observed at ASS station (northern Greece) on December 31, 1990, was not SES-activity but another disturbance or noise.

    Many studies found that stress triggering and fault interaction theories can be incorporated into quantitative earthquake probability estimates. Using two methods of time dependent probability estimates this work aims at the evaluation of the occurrence probability of anticipated earthquakes in the city of Thessaloniki, an urban center of 1 million people located in northern Greece, conditional to the time elapsed since the last stronger event on each fault of the study area and to the history of the following events on adjacent active faults. The city of Thessaloniki was chosen as a case study because is the second largest city in the territory of Greece surrounded by several small towns. The latest destructive earthquake occurred in 1978 (M=6.5) and caused the collapse of buildings and loss of life in the city and nearby villages. In this study we start from the estimate of the probability of occurrence for the stronger known earthquake on a fault in the period 2011-2041 (30 years) based on a time-dependent renewal model. For this probabilistic earthquake forecast the coseismic stress changes of strong earthquakes (M≥6.5) that occurred since the beginning of 20th century in the study area are calculated. The coseismic stress changes are translated into earthquake probability using an earthquake nucleation constitutive relation. According to this the occurrence rate of the anticipated earthquake is calculated taking into account both permanent (clock advance) and temporary (rate-and-state) perturbations. Earthquake probability on a fault is lowest after the last event but as tectonic stress grows the odds of another earthquake increase. For all needed calculations a probability density function for the time of failure for an earthquake of defined magnitude on the fault of interest must be taken into account along with the calculated stress changes on the fault. The technique for incorporating stress changes into the estimation of earthquake probability has

    Thrust tectonics and inverted metamorphic gradients are major consequences of large and likely fast movements of crustal segments in compressional environments. The purpose of this study is to investigate the tectonic setting and the timescale of inverted metamorphic zonations related to crustal-scale thrusting. The aim is to contribute understanding the link between mechanical and thermal evolution of major thrust zones and to clarify the nature and the origin of orogenic heat. The Rhodope metamorphic complex (Northern Greece) is interpreted as a part of the Alpine-Himalaya orogenic belt and represents a collisional system with an association of both large-scale thrusting and pervasive exhumation tectonics. The Nestos Shear Zone overprints the suture boundary with a NNE-dipping pile of schists displaying inverted isograds. The inverted metamorphic zones start from chlorite-muscovite grade at the bottom and reach kyanite-sillimanite grades with migmatites in the upper structural levels. In order to reconstruct the thermo-tectonic evolution of inverted metamorphic zonation, reliable geochronological data are essential. 40Ar/39Ar geochronology with step-heating technique on white mica from micaschists provided a temporal resolution with the potential to characterize shearing. 40Ar/39Ar dating across the Nestos Shear Zone yields Late Eocene-Early Oligocene (40-30 Ma) cooling (~400-350° C) ages, which correspond to local thermo-deformation episodes linked to late and post-orogenic intrusions. U-Pb Sensitive High Resolution Ion Microprobe (SHRIMP) zircon geochronology on leucosomes from migmatitic orthogneisses were considered to estimate the age of peak metamorphic conditions, contemporaneous with anatexis. U-Pb ages of zircon rims specify regional partial melting during the Early Cretaceous (160-120 Ma). This is in disagreement with previous assertions, which argued that the formation of leucosomes in this region is Late Eocene (42-35 Ma) and implied multiple

    Background The purpose of this study was to explore the effect of internal marketing on job satisfaction in health services, particularly in public hospitals in Northern Greece. Methods A questionnaire with three sections was used. The first one referred to internal marketing by using Foreman and Money's scale, while the second one contained questions on job satisfaction based on Stamps and Piermonte's work. The last section included demographic questions. Three categories of health care professionals, nurses, doctors and paramedic personnel working in public hospitals have participated. Results Doctors tend to be more satisfied with their job than nurses in the same hospitals. Male personnel also tend to be more satisfied with their job than female. Time-defined work contract personnel have a greater level of job satisfaction than permanent personnel. Marital status, position, and educational level have no statistically significant impact on job satisfaction. A slight decline in job satisfaction occurs as the personnel age. Conclusions Internal marketing has a positive effect on the job satisfaction of hospital staff in Northern Greece. Also, doctors and male personnel seem to have greater levels of job satisfaction. Staff with time-defined work contracts with the hospital are more satisfied than permanent staff, and as the staff age, there is a slight decline in job satisfaction. PMID:21981753

    The Mount Athos Peninsula is situated in the south-easternmost part of the Chalkidiki Peninsula in northern Greece. It belongs to the Serbo-Macedonian Massif (SMM), a large basement massif within the Internal Hellenides. The south-eastern part of the Mount Athos peninsula is built by fine-grained banded biotite gneisses and migmatites forming a domal structure. The southern tip of the peninsula, which also comprises Mount Athos itself, is built by limestone, marble and low-grade metamorphic rocks of the Chortiatis Unit. The northern part and the majority of the western shore of the Mount Athos peninsula are composed of highly deformed rocks belonging to a tectonic mélange termed the Athos-Volvi-Suture Zone (AVZ), which separates two major basement units: the Vertiskos Terrane in the west and the Kerdillion Unit in the east. The rock-types in this mélange range from metasediments, marbles and gneisses to amphibolites, eclogites and peridotites. The gneisses are tectonic slivers of the adjacent basement complexes. The mélange zone and the gneisses were intruded by granites (Ierissos, Ouranoupolis and Gregoriou). The Ouranoupolis intrusion obscures the contact between the mélange and the gneisses. The granites are only slightly deformed and therefore postdate the accretionary event that assembled the units and created the mélange. Pb-Pb- and U-Pb-SHRIMP-dating of igneous zircons of the gneisses and granites of the eastern Athos peninsula in conjunction with geochemical and isotopic analyses are used to put Athos into the context of a regional tectonic model. The ages form three clusters: The basement age is indicated by two samples that yielded Permo-Carboniferous U-Pb-ages of 292.6 ± 2.9 Ma and 299.4 ± 3.5 Ma. The main magmatic event of the granitoids now forming the gneiss dome is dated by Pb-Pb-ages between 140.0 ± 2.6 Ma and 155.7 ± 5.1 Ma with a mean of 144.7 ± 2.4 Ma. A within-error identical age of 146.6 ± 2.3 Ma was obtained by the U

    Tornadoes are furious convective weather phenomena, with the maximum frequency over Greece during the cold period (autumn, winter).This study analyzes the tornado event that occurred on 12 February 2010 near Vrastama village, at Chalkidiki's prefecture, a non urban area 45 km southeast of Thessaloniki in northern Greece. The tornado developed approximately between 17:10 and 17:35 UTC and was characterized as F2 (Fujita Scale). The tornado event caused several damages to an industrial building and at several olive-tree farms. A synoptic survey is presented along with satellite images, radar products and vertical profile of the atmosphere. Additionally, the nonhydrostatic WRF-ARW atmospheric numerical model (version 3.2.0) was utilized in analysis and forecast mode using very high horizontal resolution (1.333 km × 1.333 km) in order to represent the ambient atmospheric conditions. A comparison of statistical errors between WRF-ARW forecasts and ECMWF analysis is presented, accompanied with LGTS 12:00 UTC soundings (Thessaloniki Airport) and forecast soundings in order to verify the WRF-ARW model. Additionally, a comparison between WRF-ARW and ECMWF thermodynamic indices is also presented. The WRF-ARW high spatial resolution model appeared to simulate with significant accuracy a severe convective event with a lead period of 18 h.

    Polycyclic aromatic hydrocarbons (PAHs) adsorbed to ambient PM(10) were determined at three sites in Thessaloniki, northern Greece, during the period June 1997-July 1998. Ambient PAH profiles exhibited significant seasonal and spatial variations. Source PAH profiles were obtained for a number of urban, industrial and geological sources including cement, fertilizer and asphalt production, quarry operations, metal electroplating, metal welding and tempering, steel manufacture, lead and bronze smelters, metal scrap incineration, oil burning, non-catalyst equipped passenger cars, diesel fueled taxies and buses, paved road dust and soil dust. Principal component analysis (PCA) and diagnostic ratios were employed to compare ambient and source PAH profiles in an attempt to recognize compositional patterns. Similarities between the ambient PAH profiles and the profiles of certain sources, such as vehicular emissions, oil burning and metal industries, were identified. PMID:15261533

    This study investigates the water-soluble ionic constituents (Na(+), K(+), NH4 (+), Ca(2+), Mg(2+), Cl(-), NO3 (-), SO4 (2-)) associated to PM2.5 particle fraction at two urban sites in the city of Thessaloniki, northern Greece, an urban traffic site (UT) and urban background site (UB). Ionic constituents represent a significant fraction of PM2.5 mass (29.6 at UT and 41.5 % at UB). The contribution of marine aerosol was low (<1.5 %). Secondary inorganic aerosols (SIA) represent a significant fraction of PM2.5 mass contributing to 26.9 ± 12.4 % and 39.2 ± 13.2 % at UT and UB sites, respectively. Nitrate and sulfate are fully neutralized by ammonium under the existing conditions. The ionic constituents were evaluated in relation to their spatial and temporal variation, their gaseous precursors, meteorological conditions, local and long-range transport. PMID:24363054

    Northern Attica in Greece is characterized by a set of north dipping, subparallel normal faults. These faults were considered to have low tectonic activity, based on historical earthquake reports, instrumental seismicity and slip rate estimates. This study presents new data for one of these faults, the Milesi Fault. We run GIS based geomorphological analyses on fault offset distribution, field mapping of postglacial fault scarps and ground penetrating radar profiling to image hangingwall deformation. The first palaeoseismological trenching in this part of Greece allowed obtaining direct data on slip rates and palaeoearthquakes. The trenching revealed downthrown and buried palaeosols, which were dated by radiocarbon. The results of our investigations show that the slip rates are higher than previously thought and that at least four palaeoearthquakes with magnitudes of around M6.2 occurred during the last 4000-6000 yr. We calculate an average recurrence interval of 1000-1500 yr and a maximum throw rate of ˜0.4-0.45 mm a-1. Based on the new geological earthquake data we developed a seismic hazard scenario, which also incorporates geological site effects. Intensities up to IX must be expected for Northern Attica and the southeastern part of Evia. Earthquake environmental effects like liquefaction and mass movements are also likely to occur. This scenario is in contrast to the official Greek seismic hazard zonation that is based on historical records and assigns different hazard zones for municipalities that will experience the same intensity by earthquakes on the Milesi Fault. We show that the seismic hazard is likely underestimated in our study area and emphasize the need to incorporate geological information in such assessments.

    Eurasia was home to a great radiation of hominoid primates during the Miocene. All were extinct by the end of the Miocene in Western Eurasia. Here, we investigate the hypothesis of climate and vegetation changes at a local scale when the cercopithecoid Mesopithecus replaced the hominoid Ouranopithecus along the Axios River, Greece. Because they are herbivorous and were much more abundant than primates, bovids are preferred to primates to study climate change in the Balkans as a cause of hominoid extinction. By measuring carbon stable isotope ratios of bovid enamel, we conclude that Ouranopithecus and Mesopithecus both evolved in pure C3 environments. However, the large range of δ(13)C values of apatite carbonate from bovids combined with their molar microwear and mesowear patterns preclude the presence of dense forested landscapes in northern Greece. Instead, these bovids evolved in rather open landscapes with abundant grasses in the herbaceous layer. Coldest monthly estimated temperatures were below 10°C and warmest monthly temperatures rose close to or above 20°C for the two time intervals. Oxygen isotope compositions of phosphate from bulk samples did not show significant differences between sites but did show between-species variation within each site. Different factors influence oxygen isotope composition in this context, including water provenience, feeding ecology, body mass, and rate of amelogenesis. We discuss this latter factor in regard to the high intra-tooth variations in δ(18)Op reflecting important amplitudes of seasonal variations in temperature. These estimations fit with paleobotanical data and differ slightly from estimations based on climate models. This study found no significant change in climate before and after the extinction of Ouranopithecus along the Axios River. However, strong seasonal variations with relatively cold winters were indicated, conditions quite usual for extant monkeys but unusual for great apes distributed today in

    In November 1994, a geodetic network situated on the Mygdonian graben, 30 km NE of Thessaloniki, Greece, was remeasured using the GPS technique. This network was established in 1979, in the epicentral area of the 1978 earthquake (Ms=6.5), and was measured using triangulation techniques seven times between 1979 and 1989. The comparison between 1979 and 1994 data shows that this part of the Mygdonian graben experienced about 8 cm of N-S horizontal extension. Most of the extension is concentrated in a narrow (one or two kilometers) E-W zone, located on the southern boundary of the graben. Furthermore, the analysis of repeated triangulation surveys suggests a rate of extension of 5.7±1.3 mm/y, that remained constant with time between 1979 and 1994. This extension could result from long-term postseismic relaxation processes, or from continous aseismic slip within the graben.

    Tornadoes are furious convective weather phenomena, having increased frequency, particularly in the cool season, attributed to the higher moisture content of the atmosphere due to global warming. Tornadoes' source regions are more likely shallow waters, which are easily warmed, such as Gulf of Mexico or Mediterranean Sea. This study analyzes the tornado event, that occurred on 12 February 2010 in Vrastera, Chalkidiki, a non urban area 45 km southeastern of Thessaloniki in northern Greece. The tornado was developed approximately between 17:15 and 18:45 UTC and characterized as F2 (Fujita Scale). The tornado caused several damages to an industrial building and an olive-tree farm. A synoptic analysis based on the ECMWF charts is presented along with an extended dataset of satellite images, radar products and vertical profile of the atmosphere. Additionaly, the nonhydrostatic WRF-ARW atmospheric numerical model (version 3.2) was utilized in analysis and forecast mode using very high horizontal resolution (1 km x 1 km) in order to represent the ambient atmospheric conditions and examine the prediction of the event. Sensitivity experiments look into the model performance in the choice of microphysical and boundary layer parameterization schemes.

    Spatial explicit knowledge regarding the quantity and the spatial distribution of forest parameters is crucial for sustainable forest management, as well as in fulfilling national reporting needs in the framework of international treaties (i.e. Kyoto Protocol, FAO, EFFIS etc). Especially, tree number which can be used for assessing forest tree density (tree number/ha), is among the most important and laboursome parameters to be measured in the field. The aim of this study is to estimate tree number based on the use of nationwide, freely available, very high spatial resolution orthophotos acquired from Greek National Cadastre and Mapping Agency during the 2007-2009 period. The study area is the University Forest of Taxiarchis, which is located in central Halkidiki, Northern Greece. The dominant species of the forest includes both broadleaves (oak, beech) and coniferous species (Black pine, Calabrian pine), which are found in both pure and mixed stands. Tree crown detection was tested on natural color orthophoto bands in several plots. The principal components and intensity-hue-saturation transformations were also applied in order to enhance tree detection accuracy. Local maxima technique was utilized for tree crown detection. Accuracy results were evaluated based on field plot data available from the official forest management plan of the area completed in 2011. Overall, the detection accuracy exceeded 50% which is deemed satisfactory considering also the heterogeneity of the Mediterranean landscape and the limited spectral resolution of the remote sensing data available.

    In this study an attempt is made in order to determine the palaeogeographic evolution of Alykes lagoon, located along the microtidal coast of Pieria Prefecture in northern Greece. For this purpose, sedimentological, micro and macropalaeontological and granulometric analyses have been carried out on sediments that have been collected from two drill cores. The total area of Alykes lagoon is 10.78 km2 while the length of the coastline is 11.4 km with a maximum width of 320 m, not exceeding an elevation of 1m. The lagoon in its present form does not seem to be filling up by terrestrial-fluvial action. The only human activity in the study area is the saltworks in the northern part of the lagoon. Two zones have been recognized according to their microfossil content corresponding to different palaeoenvironments of deposition.During the Holocene the sea invaded this lowland area and created a shallow open marine environment which at times was disturbed by multiple terrestrial inputs induced by fluvial discharge and longshore drift. The prevailing drift is from South to North and has contributed to the formation of a barrier spit which extended towards the NNE and finally confined the lagoon in the northwest. The spit has advanced to the east by forming three generations of ridge and swale topography having a slightly different orientation. Based on a radiocarbon date at -4.4 m below sea level obtained from the southern part of the lagoon, it is assumed that the coastline was already at that location by the end of the seventh millennium BP. Given that the drill core is only about twenty meters from the terrestrial outcrops (Neogene formations) we presume that this was the location of the oldest coastline during the Holocene. Therefore, the formation and evolution of the lagoon can be safely put around the sixth millennium BP.

    Extensive measurements of Rn-222 in the town of Xanthi in N Greece show that the part of the town overlying granite deposits and the outcrop of a uranium ore has exceptionally high indoor radon levels, with monthly means up to 1500 Bq m-3. A large number of houses (40%) in this part of the town exhibit radon levels above 200 Bq m-3 while 11% of the houses had radon levels above 400 Bq/m3. Substantial interannual variability as well as the highest in Europe winter/summer ratios (up to 12) were observed in this part of the town, which consist of traditional stone masonry buildings of the late 19th- early 20th century. Measurements of U-238 and Th-232 content of building materials from these houses as well as radionuclide measurements in different floors show that the high levels of indoor radon measured in these buildings are not due to high radon emanation rates from the building materials themselves but rather due to high radon flux from the soil because of the underlying geology, high radon penetration rates into the buildings from underground due to the lack of solid concrete foundations in these buildings, or a combination thereof. From the meteorological variables studied, highest correlation with indoor Rn-222 was found with temperature (r2=0.65). An indoor radon prognostic regression model using temperature, pressure and precipitation as input was developed, that reproduced indoor radon with r2=0.69. Hence, meteorology is the main driving factor of indoor radon, with temperature being the most important determinant. Preliminary flux measurements indicate that the soil-atmosphere Rn-222 flux should be in the range 150-250 Bq m-2 hr-1, which is in the upper 10% of flux values for Europe.

Substantial interannual variability as well as the highest in Europe winter/summer ratios (up to 12) were observed in this part of the town, which consist of traditional stone masonry buildings of the late 19th-early 20th century. Measurements of (238)U and (232)Th content of building materials from these houses as well as radionuclide measurements in different floors show that the high levels of indoor radon measured in these buildings are not due to high radon emanation rates from the building materials themselves but rather due to high radon flux from the soil because of the underlying geology, high radon penetration rates into the buildings from underground due to the lack of solid concrete foundations in these buildings, or a combination thereof. From the meteorological variables studied, highest correlation with indoor (222)Rn was found with temperature (r(2) = 0.65). An indoor radon prognostic regression model using temperature, pressure and precipitation as input was developed, that reproduced indoor radon with r(2) = 0.69. Hence, meteorology is the main driving factor of indoor radon, with temperature being the most important determinant. Preliminary flux measurements indicate that the soil-atmosphere (222)Rn flux should be in the range 150-250 Bq m(-2) h(-1), which is in the upper 10% of flux values for Europe. PMID:26372739

    A new occurrence of Mn-rich rocks was discovered within the high-pressure/low-temperature metamorphic rocks on the Palos peninsula of Syros (Greece). Near the summit of Mount Príonas, a meta-conglomerate consists of calcite (~63 wt%), pink manganian phengite, blue-purple manganian aegirine-jadeite, microcline, albite and quartz. In addition, it contains abundant braunite-rich aggregates (up to ~1.5 cm in diameter) that include hollandite [(Ba0.98-1.02K<0.01Na<0.02Ca<0.03) (Mn{1.02-1.52/3+}Fe{0.38-0.88/3+}Ti0.29-0.92Mn{5.11-5.76/4+})O16], barite and manganian hematite. Due to metamorphic recrystallization and deformation, the contacts between clasts and matrix are blurred and most clasts have lost their identity. In back-scattered electron images, many aegirine-jadeite grains appear patchy and show variable jadeite contents (Jd10-67). These pyroxenes occur in contact with either quartz or albite. Manganian phengite (3.41-3.49 Si per 11 oxygen anions) is of the 3T type and contains 1.4-2.2 wt% of Mn2O3. At the known P- T conditions of high-pressure metamorphism on Syros (~1.4 GPa/ 470 °C), the mineral sub-assemblage braunite + quartz + calcite (former aragonite) suggests high oxygen fugacities relative to the HM buffer (+7 ≤ ∆fO2 ≤ + 17) and relatively high CO2 fugacities. The exact origin of the conglomerate is not known, but it is assumed that the Fe-Mn-rich and the calcite-rich particles originated from different sources. Braunite has rather low contents of Cu (~0.19 wt%) and the concentrations of Co, Ni and Zn are less than 0.09 wt%. Hollandite shows even lower concentrations of these elements. Furthermore, the bulk-rock compositions of two samples are characterized by low contents of Cu, Co and Ni, suggesting a hydrothermal origin of the manganese ore. Most likely, these Fe-Mn-Si oxyhydroxide deposits consisted of ferrihydrite, todorokite, birnessite, amorphous silica (opal-A) and nontronite. Al/(Al + Fe + Mn) ratios of 0.355 and 0.600 suggest the

    Exposure of the forearc region of the North Aegean Sea, Greece, offers insight into evolving convergent margins. The sedimentary fill of the Thrace Basin during the Late Eocene to Oligocene time provides a record of subduction-driven processes, such as growth of magmatic arcs and construction of accretionary complexes. This large sediment repository received sediment from two sources. The southern (outboard) basin margin reflects the active influence of the exhumed accretionary prism (e.g. Pindic Cordillera or Biga peninsula), while the northern (inboard) margin records the effect of the magmatic arc in the Rhodope region. The forearc basin sedimentary fills shoal upward into shallow-marine strata but are dominated mainly by deep-marine facies. The depositional trend and stacking pattern are dominated by progradational patterns. This trend, which is observed in both basin margins, is related to tectonic deformation rather than sea-level fluctuations. Additional evidence for this tectonic uplift comes from the backstripping analysis. The accretionary complex provided material into the forearc basin. This material was transported northeast and formed a sand-rich turbidity system that evolved upslope into shallow-marine deposits. Stratigraphic data indicate that this turbidity system exhibits a successive landward (inboard) migration of the depocenter. Provenance data utilizing sandstone petrography, conglomerate clast composition, and bulk-rock geochemistry suggest that this system reflects an increased influx of mafic material into the basin. Volcanic arc-derived material was transported south and east and accumulated in deep-marine settings. Both stratigraphic and provenance data indicate a seaward (outboard) migration of the basin depocenter and a significant increase in felsic detritus into the forearc.

    We recently commenced a project to investigate deep drillings as well as outcrops in the Ptolemais Basin, northern Greece, for paleoenvironmental and paleoclimate change. Specific attention is paid to mining sites Achlada, Vevi, Vegora, Amynteon, North Field, South Field, and Lava. The sediment archive comprises Upper Miocene to Quaternary continental lake deposits (up to 800 m thick) with an extended Lower Pliocene section. The Upper Miocene sections are composed of diatomaceous mud and gray marls. Pliocene lake sediments commence with the Kyrio member (lignite/grey marl), followed by the Theodoxus member (beige marl/lignite), and the Notio member (marl with intercalated sand /lignite). The limnic deposits show striking rhythmic bedding of (mostly) carbonates and lignites, reflecting orbital-induced humidity and temperature changes in this small NW-SE elongated continental basin. First, we retrieved chronometric information by determining magnetic polarity changes on three sites as independent stratigraphic ground-truth in combination with palynological evidence and published data. Then we conducted a number of high-resolution (1 - 6 cm increment), non-destructive measurements to obtain paleoclimate proxies: photospectrometry (colors L, a, b), magnetic susceptibility, and natural gamma. Accordingly, we achieved a multi-proxy insight into paleoclimate and paleoenvironmental evolution at unprecedented temporal resolution (up to a few decades!) over long time series and at a number of key sites. Using the newly-developed ESALab software, we conducted spectral and evolutionary spectral analysis to evaluate the cyclo-stratigraphic development. As for orbital variability, spectral power is concentrated on precession, hemi-precession, and eccentricity, with only minor impact of orbital tilt. We used this information to increase the temporal resolution of our age models by tuning as many precession (insolation) maxima as possible to carbonate minima (lignite maxima

    Common farmland birds are declining throughout Europe; however, marginal farmlands that escaped intensification or land abandonment remain a haven for farmland species in some Mediterranean mountains. The purpose of this study is to identify the most important anthropogenic microhabitat characteristics for Red-Backed Shrike ( Lanius collurio), Corn Bunting ( Miliaria calandra) and Common Whitethroat ( Sylvia communis) in three such areas within the newly established Northern Pindos National Park. We compare land use structural and physiognomic characteristics of the habitat within 133 plots containing birds paired with randomly selected “non-bird” plots. Using logistic regression and classification-tree models we identify the specific habitat requirements for each of the three birds. The three species show a preference for agricultural mosaics dominated by rangelands with scattered shrub or short trees mixed with arable land. Areas with dikes and dirt roads are preferred by all three species, while the presence of fences and periodically burned bushes and hedges are of particular importance for Red-Backed Shrike. Across the gradient of vegetation density and height, M. calandra is mostly found in grasslands with few dwarf shrubs and short trees, S. communis in places with more dense and tall vegetation of shrub, trees and hedges, and L. collurio, being a typical bird of ecotones, occurs in both habitats and in intermediate situations. In all cases those requirements are associated with habitat features maintained either directly or indirectly by the traditional agricultural activities in the area and particularly by the long established extensive controlled grazing that prevent shrub expansion.

    We present the state-of-the-art of the Greek Database of Seismogenic Sources (GreDaSS). The major goals of this international scientific project are (i) the systematic collection of all available information concerning active faults, potentially active faults and seismogenic volumes within the broader Aegean Region; (ii) the quantification of the principal seismotectonic parameters of the different sources as well as their degree of uncertainty; (iii) to supply an integrated view of potentially damaging seismogenic sources for a better assessment of the seismic hazard of Greece. The informatic framework of the database follows closely that used for the Italian Database of Individual Seismogenic Sources (DISS), which represents the result of more than ten years experience of its Working Group (e.g. Basili et al., 2008). This preliminary version of GreDaSS is focused on northern Greece, where we distinguish two main categories of Seismogenic Sources based on their attributes, their expected use, the nature and reliability of data used to define them: - "Individual Seismogenic Sources" (GGSources) are obtained from geological and geophysical data and are characterized by a full set of geometric (strike, dip, length, width and depth), kinematic (rake) and seismological-palaeoseismological parameters (average displacement, magnitude, slip rate, recurrence interval) and by a rating of the associated uncertainties. Individual Seismogenic Sources are assumed to exhibit "characteristic" behaviour with respect to rupture length/width and expected mean and maximum magnitude. They are tested against worldwide databases for internal consistence in terms of length, width, average displacement and magnitude. This category of sources favours accuracy of the information supplied over completeness of the sources themselves. As such, they can be used for deterministic assessment of seismic hazard, for calculating earthquake and tsunami scenarios, and for tectonic and geodynamic

    The Chalkidiki block in Northern Greece represents the southwesternmost piece of the ultrahigh-pressure Rhodope and has played an important role in the evolution of the North Aegean. The eastern part of the Chalkidiki block is a basement complex (Vertiskos Unit) that is made largely of Palaeozoic granitoids and clastic sediments that metamorphosed during the Mesozoic. This basement is traditionally considered as part of the Rhodopean hanging-wall, an assignment mainly supported by the absence of high-pressure mineral indicators and the presence of a regional medium-pressure/medium-temperature amphibolite-facies Barrovian metamorphic imprint. Toward the west, the basement is juxtaposed with meta-sedimentary (Circum-Rhodope belt) and arc units (Chortiatis Magmatic Suite) that carry evidence of a Mesozoic high-pressure/low-temperature event. In this study, garnet-staurolite-mica schists from the eastern part of the basement were examined by means of micro-textures, mineral chemistry and isochemical phase-diagram sections in the system NCKFMASHMn(Ti) [Na2O-CaO-K2O-FeO-MgO-Al2O3-SiO2-H2O-MnO-(TiO2)]. The schists represent former Mesozoic sedimentary sequences deposited on the Palaeozoic basement. We document the presence of a relict eclogite-facies mineral assemblage (garnet + chloritoid + phengite + rutile) in an amphibolite-facies matrix composed of garnet + staurolite + phengite ± kyanite. Model results suggest the existence of a high-pressure/medium-temperature metamorphic event (1.9 GPa/520 °C) that preceded regional re-equilibration at medium-pressure/medium-temperature conditions (1.2 GPa/620 °C). Clearly, the eastern part of the Chalkidiki block (basement complex) retains memory of an as yet unidentified Mesozoic eclogitic metamorphic event that was largely erased by the later Barrovian overprint. In light of our findings, the basement complex of the Chalkidiki block shares a common tectono-metamorphic evolution with both the high-pressure units to the west

    Available information on the socioeconomic implications of marine protected areas (MPAs) for the socioculturally diverse Mediterranean region is scant. The National Marine Park of Alonissos, Northern Sporades (NMPANS), Greece was established in 1992 as a foundation for the conservation of the endangered Mediterranean monk seal Monachus monachus. The evolution of the degree of acceptance of and satisfaction from the NMPANS by involved stakeholder groups (fishermen, tourism operators, hoteliers and owners of rooms to let, governmental bodies, nongovernmental bodies, students, domestic and foreign tourists) were investigated 13 years after its establishment using written questionnaires delivered during personal interviews. The initial positive attitude of local professionals for the NMPANS has eroded due to the unsatisfactory fulfillment of expectations for socioeconomic development. Fishermen expressed dissatisfaction with, mistrust toward, and a reluctancy to communicate with the NMPANS’s management body. They believe that the fishery areas have decreased in actual geographic area because of the prohibitive measures; fish stocks are declining; compensation for damage to fishery equipment by the Mediterranean monk seal and for the prohibitive measures should be provided; and stricter enforcement of regulations should take place. On the other hand, tourism operators, who organize trips for tourists to the NMPANS, unanimously reported direct economic benefits. Furthermore, there was a disparity in the perception of socioeconomic benefits derived from the NMPANS between governmental bodies and local stakeholders. The governmental bodies and the nongovernmental organization MOm-Hellenic Society for the Study and Protection of the Monk Seal postulated that there had been considerable socioeconomic benefits for the local community of Alonissos due to the establishment of the NMPANS, whereas the local nongovernmental organization Ecological and Cultural Movement of

    Land subsidence is a common phenomenon occurring in several regions worldwide. Persistent subsidence causes strong consequences on the affected areas and related problems include environmental, economic and social aspects. A set of forty-two Synthetic Aperture Radar (SAR) images, acquired in 1995-2001 by the European Space Agency (ESA) satellites ERS1 and ERS2, were processed with Persistent Scatterer Interferometry (PSI) technique to investigate spatial and temporal patterns of deformation in the Delta municipality (Thessaloniki plain, Northern Greece), a deltaic area with a long history of land subsidence related to aquifer system compaction. Exploitation of output products of a PSI analysis, both average LOS (Line of Sight) deformation rates and displacement time series, revealed a large subsidence area due to intense groundwater withdrawal. Higher displacement velocities have been observed south-west of Kalochori and south of Sindos, from both sides of the Gallikos River. In those areas deformation rates of roughly 4.5 cm/yr have been recorded, during the period from 1995 to 2001. Increasing subsidence rates are measured moving toward the mouth of the Gallikos River, where the thickest sequence of compressible Quaternary sediments is observed. Displacement time series retrieved by PSI technique has been compared with the temporal evolution of the deformation as measured by pre-existing leveling surveys, showing a great agreement. A 2-D finite element model has been run along two representative cross sections in the Kalochori area, in order to simulate the observed temporal evolution of subsidence, coupling the geotechnical behavior of the formations and the piezometric surface level. Finally, results obtained by the subsidence model have been positively compared with the PSI-based information on displacement, providing accurate and perfectly verified results. Outcomes of this work demonstrated the potential of repeat-pass satellite SAR interferometry (InSAR) as

    Organic carbon (OC) and elemental carbon (EC) concentrations, associated to PM10 and PM2.5 particle fractions, were concurrently determined during the warm and the cold months of the year (July-September 2011 and February-April 2012, respectively) at two urban sites in the city of Thessaloniki, northern Greece, an urban-traffic site (UT) and an urban-background site (UB). Concentrations at the UT site (11.3 ± 5.0 and 8.44 ± 4.08 14 μg m(-3) for OC10 and OC2.5 vs. 6.56 ± 2.14 and 5.29 ± 1.54 μg m(-3) for EC10 and EC2.5) were among the highest values reported for urban sites in European cities. Significantly lower concentrations were found at the UB site for both carbonaceous species, particularly for EC (6.62 ± 4.59 and 5.72 ± 4.36 μg m(-3) for OC10 and OC2.5 vs. 0.93 ± 0.61 and 0.69 ± 0.39 μg m(-3) for EC10 and EC2.5). Despite that, a negative UT-UB increment was frequently evidenced for OC2.5 and PM2.5 in the cold months possibly indicative of emissions from residential wood burning at the urban-background site. At both sites, cconcentrations of OC fractions were significantly higher in the cold months; on the contrary, EC fractions at the UT site were prominent in the warm season suggesting some influence from maritime emissions in the nearby harbor area. Secondary organic carbon, being estimated using the EC tracer method and seasonally minimum OC/EC ratios, was found to be an appreciable component of particle mass particularly in the cold season. The calculated secondary contributions to OC ranged between 35 and 59 % in the PM10 fraction, with relatively higher values in the PM2.5 fraction (39-61 %). The source origin of carbonaceous species was investigated by means of air parcel back trajectories, satellite fire maps, and concentration roses. A local origin was mainly concluded for OC and EC with limited possibility for long range transport of biomass (agricultural waste) burning aerosol. PMID:23979848

    An on-going study of the hoverfly fauna of the Northern Aegean Islands (Greece) has revealed the presence of four species of the genus Brachyopa Meigen. During the survey the following species were found: B. bicolor (Fallén), B. quadrimaculosa Thompson in Kaplan & Thompson, B. minima Vujić & Pérez-Bañón sp. nov. and an unidentified species very close to B. pilosa (Collin). Morphological characters and mitochondrial COI barcodes were used to link different life stages of B. minima, and to identify a larval specimen of B. bicolor. In this study adult and larval morphology and habitat preferences for B. minima are described. The description of larval morphology of B. bicolor and Brachyopa sp. aff. pilosa is amended too. An identification key to the adults of the B. quadrimaculosa group sensu Kassebeer (2002) in the Eastern Mediterranean (Greece, Israel and Turkey) is provided. The importance of specific microhabitats for the continued existence of these taxa is discussed. PMID:27395920

    Energy-dispersive X-Ray fluorescence spectrometry was used to determine the concentrations of copper (Cu), zinc, iron and molybdenum in the liver of 76 sheep and goats from the regions of Macedonia-Thrace, northern Greece. In general, metal concentrations were in the adequate range, with one main exception of Cu-deficiency observed in all of the examined goat liver samples and Cu-toxicity found in 4 % of the sheep liver samples. One-way analysis of variance was carried out to determine significant differences among means depending on animal species, sex and age. Pearson correlation analysis was used to explore correlations between metal concentrations. The results obtained in the present study are discussed in the framework of diagnostic ranges, suggested for classifying the metal status of sheep and goats, and are compared with liver metal concentrations reported world-wide.

    Just before dying, Edessa rufomarginata (Hemiptera, Pentotomidae) individuals that are infected with the fungus Purpureocillium cf. lilacinum (Ascomycota: Ophiocordycipitaceae) move from the leaves onto the stems of their Solanum sp. host and firmly grasp the stems in ways seldom employed by uninfected bugs. These alterations in host behavior probably improve the chances that the subsequently produced fungal spores will be dispersed aerially. Purpureocillium cf. lilacinum is a member of the Ophiocordycipitaceae, a group in which other species also modify the behavior of their hosts. As in the case of newly distinguished relatives of Ophiocordyceps unilateralis associated with "zombie ants" the discovery of P. cf. lilacinum infecting bugs reveals that P. lilacinum may be more diverse than previously appreciated.

    The potential of repeat-pass space borne SAR (Synthetic Aperture Radar) interferometry has been exploited to investigate spatial patterns of land subsidence in the Anthemountas basin, in the northern part of Greece. The PSI (Persistent Scatterer Interferometry) approach, based on the processing of long series of SAR acquisitions, has been applied to forty-two images acquired in 1995-2001 by ERS1/2 satellites. Interferometric results have been analyzed at a basin scale as support for land motion mapping and at local scale for the characterization of ground motion events affecting the village of Perea in the Thermaikos municipality and the "Macedonia" international airport. PSI results revealed a moderate subsidence phenomenon along the wider coastal zone of Anthemountas basin corresponding to intense groundwater extraction. Highest values, exceeding 20 mm yr-1, were measured in the airport area where the thickest sequence of compressible Quaternary sediments occurs. Intense subsidence has been detected also in the Perea village (maximum deformation up to 10-15 mm yr-1), where a series of fractures, causing damages to both buildings and infrastructure, occurred in 2005-2006. Furthermore, a linear pattern of deformation, elongated parallel to the major normal Thermi fault, has been observed, indicating movements with a probable tectonic component.

    Since 1951, the character of Greece has changed from a mainly agricultural into a more industrial country. In the course of the economic revival, this change implied a rapid development of urban and industrial areas, resulting in serious consequences for the Hellenic environment. The present study focuses on fly ash and heavy metal pollution, one of the major environmental problems of the broader Kozani - Ptolemaida region (northern Greece) where five power plants are operating. The target of the project was twofold: (a) to challenge the correlation between ferrimagnetic mineral content and geochemical properties of samples from polluted areas, (b) to estimate the spatial distribution of several pollutants within the study area. Towards this scope, the magnetic susceptibility was mapped using a Bartington susceptibility meter (MS2D-loop) with a resolution of 1Ã-1 km, and soil samples were collected from each measurement point. After drying and sieving, the specimens were subjected to several laboratory experiments: measurement of magnetic low-field susceptibility at low and high frequency, isothermal remanence acquisition, thermomagnetic analyses, alternating field demagnetization of both natural and isothermal remanent magnetization, anhysteretic remanence experiments and hysteresis loops. The concentrations of Fe, Mn, Cr, Cu, Pb and Zn in the studied soils were determined by X-ray fluorescence and ICP-AES analyses were carried out on HNO3 digests from the same samples. The in-situ susceptibility values exhibit significant variation, ranging from very low background values (7Ã-10-5 SI) to high values (730Ã-10-5 SI), with a mean of 141Ã-10-5 SI. The same variation arises from laboratory susceptibility measurements at low and high frequency, with a mean frequency dependence (F-factor) of 5 %. Preliminary geochemical measurements indicate concentrations of 40-360 mg(Cr3+)/kg, 10-30 mg(Cu)/kg, 3523-21543 mg(Fe)/kg, 195-1150 mg(Mn)/kg, 46-471 mg(Ni)/kg, 3-25 mg

    Air samples were collected during the cold and the warm period of the year 2012 and 2013 at three sites in the major Thessaloniki area, northern Greece (urban-industrial, urban-traffic and urban-background) in order to evaluate the occurrence, profiles, seasonal variation and gas/particle partitioning of polybrominated diphenyl ethers (PBDEs). The mean total concentrations of particle phase ∑12PBDE in the cold season were 28.7, 19.5 and 3.87 pg m(-3) at the industrial, urban-traffic and urban-background site, respectively, dropping slightly in the warm season (23.7, 17.5 and 3.14 pg m(-3)), respectively. The corresponding levels of gas-phase ∑12PBDE were 14.4, 7.15 and 4.73 pg m(-3) in the cold season and 21.2, 11.1 and 6.27 pg m(-3) in the warm season, respectively. In all samples, BDE-47 and BDE-99 were the dominant congeners. Absorption of PBDEs in the organic matter of particles appeared to drive their gas/particle partitioning, particularly in the cold season. The estimated average outdoor workday inhalation exposure to ∑12PBDE in the cold and the warm period followed the order: industrial site (288 and 299 pg day(-1)) > urban-traffic site (178 and 191 pg day(-1)) > urban-background site (58 and 63 pg day(-1)). The exposures to BDE-47, BDE-99, BDE-153 and ∑3PBDE via inhalation, for children outdoor worker and seniors were several orders of magnitude lower than their corresponding oral RfD values.

    Local distrust for Marine Protected Area (MPA) managers is emerging as an important factor obstructing the fulfillment of MPA objectives, and, thus, there is a need to develop a means of enhancing relationship building between MPA managers and local people. We used the National Marine Park of Alonissos, Northern Sporades (NMPANS), Greece, as a relevant case-study to investigate whether the local print media's framing of the marine park and its management affected locals' attitudes. We conducted a longitudinal review of local newspaper articles pertaining to the NMPANS during 1980-2008, and we conducted telephone interviews with local people. We found that salience of the NMPANS in the local print media remained limited and sporadic, the main stakeholder remained the centralized public sector, and the regional print media was rather detached, moderate, and largely supportive of the NMPANS throughout 1980-2008. The progression of the management periods of the NMPANS, however, was accompanied by increased importance of the NMPANS, increased deviance from conservation as the chief objective of the NMPANS's establishment, a shift from presenting facts to presenting reactions, and a shift from a positive to a mixed image of the NMPANS. Locals who relied on newspapers for local news were better informed about the NMPANS, more likely to accept the NMPANS, and more likely to participate in meetings regarding the NMPANS regardless of gender, age, and occupation than those who did not rely on newspapers. The local print media may be utilized as a free-choice learning vehicle to enhance the value of an MPA among local people and to enhance the development of trust between park managers and locals through a proactive, empowering, and cognitive media strategy.

    The mass concentration and the elemental composition of PM 2.5 and PM 10 were measured in 40 rooms (mainly offices or mixed office-lab rooms, and photocopying places) of the Aristotle University of Thessaloniki, northern Greece. A total of 27 major, minor and trace elements were determined by ED-XRF analysis. The PM 2.5/PM 10 concentration ratios averaged 0.8±0.2, while the corresponding elemental ratios ranged between 0.4±0.2 and 0.9±0.2. The concentrations of PM 2.5 and PM 10 were significantly higher (by 70% and 50%, respectively) in the smokers' rooms compared to the non-smokers' places. The total elemental concentrations were also higher in the smokers' rooms (11.5 vs 8.2 μg m -3 for PM 2.5, and 10.3 vs 7.6 μg m -3 for PM 2.5-10). Fine particle concentrations (PM 2.5) were found to be quite proportional to smoking strength. On the contrary, the two environments exhibited similar coarse (PM 2.5-10) particle fractions not related to the number of cigarettes smoked. A slight decrease of particle concentrations with increasing the floor level was also observed, particularly for PM 2.5, suggesting that high-level floors are less impacted by near ground-level sources like traffic emissions. Finally, the removal efficiency of air purification systems was evaluated.

    The concentration and chemical fractionation of some heavy metals (Mn, Pb, Zn, Cu, Cd) and As in agricultural soils of the western Drama plain (northern Greece) were determined using inductively coupled plasma-mass spectrometry (ICP-MS) technique. Drama plain constitutes the recipient of the effluents from Xiropotamos stream, which passes through the abandoned "25 km Mn-mine" place. Results showed that soils were found to have elevated concentrations of potentially harmful elements which are mainly associated with Mn mineralization. Peak total concentrations (in mg kg(-1)) of 130,013 for Mn, 1996 for Pb, 2140 for Zn, 147 for Cu, 28 for Cd, and 1077 for As were found in sampling points close and along both sides of the Xiropotamos stream, as a result of downstream transfer and dispersion of Mn mine wastes via flooding episodes. Contaminated sites are important sources of pollution and may pose significant environmental hazards for terrestrial and aquatic ecosystems. The geochemical influence of the mine wastes as a source of soil pollution is substantially reduced in sites 200 m remote of the Xiropotamos stream course. The chemical partitioning patterns indicated that the potential for Mn, Pb, Zn, Cu, Cd, and As remobilization and bioavailability is low, as most of these elements were present in the residual and/or the more stable Mn- and Fe-hydroxide fractions. The partitioning in significant percent (14-25 %) of Cd with the weakly bound exchangeable/carbonate fraction indicated that this metal could be highly mobile as well as bioavailable in the studied contaminated soils and this could be concern to human health.

    Upper crustal extensional structures range from steep normal faults to shallow-dipping detachments. The relationship between extension and formation of synkinematic hanging wall basins including their relative timing is not well understood. The South Rhodope core complex, Southern Balkans, has experienced extension for >40 Ma leading to a number of extensional structures and Cenozoic sedimentary basins. We present new bedrock and basin detrital zircon and apatite (U-Th-Sm)/He ages from the Pirin and Rila Mountains and the Sandanski basin. Results identify three episodes of Cenozoic extension in SW Bulgaria accommodated by (1) the Eocene/Oligocene Mesta detachment; (2) the early to middle Miocene Gorno Spanchevo fault (circa 18-15 Ma), which is the northern prolongation of the Strymon low-angle detachment; and (3) the late Miocene West Pirin fault (≤10 Ma). Detachment faulting on the Strymon fault accommodated tens of kilometers of ENE-WSW extension and created ~1500 m topographic relief, but because the resulting hillslopes were gentle (≤10°), extension did not lead to enhanced footwall erosion or formation of a hanging wall basin. In contrast, the West Pirin normal fault resulted in mostly vertical motion of its footwall causing steep topography, rapid erosion, and formation of the synrift Sandanski basin. Digital topographic analysis of river channel profiles identifies the latest episodes of deformation including westward tilting of the Sandanski and Strymon basins and Quaternary N-S extension. This study demonstrates that basin formation in the South Rhodope core complex is related to normal faulting postdating the main episode of crustal stretching by detachment faulting.

    Leptospirosis is a zoonotic disease with increased public health concern worldwide. The disease occurs more often in temperate and tropical regions. The present study analyzes the demographic, epidemiological and clinical data of 168 leptospirosis cases laboratory diagnosed in northern Greece during 1998-2014. Most patients were males, aged 50-69 years, working in animal husbandry or farming. Cases were observed more frequently in summer and autumn. Severity of the disease was correlated with presence of pulmonary involvement and hemorrhagic manifestations. PMID:26026714

    The preliminary results from a new paleoseismological investigation carried out along the Paleochori-Sarakina fault segment, West Macedonia, Northern Greece, are presented. The Paleochori-Sarakina fault is a SW-NE trending north-dipping normal fault, which was ruptured during the 13th May 1995 devastating earthquake (Ms = 6.6) that affected the Kozani-Grevena area. The 10-km-long Paleochori-Sarakina fault is expressed as a complex, 15- to 50-m-high escarpment on early-middle Miocene molassic sediments of the Meso-Hellenic trench and it forms the southeast segment of the Aliakmon river Fault system. A series of surface ruptures, with a maximum displacement of ~10 cm, were created during the 1995 earthquake in the area between Paleohori and Sarakina villages. Several trenches were excavated along the Paleohori-Sarakina fault right after the 1995 earthquake and three previous faulting events were identified. Thermoluminescence (TL) dating has been used to date the recognized paleoearthquakes. Recurrence interval based on these TL ages was 30 ka which was extremely high and the estimated slip-rate extremely low (0.01-0.03 mm/a). We excavated two new paleoseismological trenches near the Paleochori village in order to improve our knowledge on the Holocene tectono-stratigraphy of this structure and to obtain new samples for dating using an improved dating technique. The first trench was located 500 m southeast from the Paleochori village and was excavated across a 1.5-m-high north-facing fault scarp. The trench was 30 m long and up to 4 m deep. The second trench was located at the base of a 5-m-high scarp at the northeastern end of the Paleochori-Sarakina fault segment, south of the Paleochori village. The trench was 17 m long and up to 3 m deep. Both trenches intersect the fault zone which separates mollasic sediments exposed on the upthrown block from colluvial deposits of the downthrown block. The initial preliminary interpretation of the trench wall structure provided

  7. Tornadoes and waterspouts in Greece

    NASA Astrophysics Data System (ADS)

    Sioutas, Michalis V.

    Tornadoes and waterspouts occur in various parts of Greece and may often reach the media as remarkable events, depending of their intensity and the level of damage. This paper is based on a research started from the beginning of 2000 for identifying and recording tornadoes and waterspouts in Greece and evaluating their intensity and other fundamental characteristics. Search of historical events for obtaining more comprehensive tornado climatology is in progress. In an almost 3-year period, January 2000-September 2002, tornadoes and waterspouts have been reported from various parts of Greece, including western Greece, the Ionian islands and western Peloponnese mainly during autumn and winter. Northern Greece is affected by tornadic activity mostly during summer and early autumn. The geographical distribution showed a preference for tornado occurrence mainly in coastal areas. Based on this almost 3-year data sample, a mean number of six tornadoes per year has resulted, corresponding to a density of 0.45 10 -4 km -2 year -1. Maximum intensity of tornadoes recorded was rated as T6 of the Tornado and Storm Research Organization (TORRO) scale (F3 of the Fujita scale). A basic synoptic typing scheme is presented, including four synoptic circulation patterns associated to tornado occurrence.

    Ambient noise array tomography has been recently recognized as a promising tool for the study of the shallow 2D/3D geophysical structure. The method basis relies on the implementation of cross-correlation analysis on ambient noise data, which is able to provide the Green's Function of the medium between two spatially separated recording stations (Gouedard et al. 2008). The obtained cross-correlation trace contains information about the group and phase velocity of the surface waves that are dominant in the ambient noise wavefield. A typical application, similar to larger-scale studies, employs appropriate narrow-band Gaussian filters on the cross-correlation trace (Multiple Filter Analysis), allowing the construction of the group velocity dispersion curves for selected paths within the study area. An inversion procedure leads to tomographic images (group velocity maps for specific frequencies), which can be locally inverted to derive 1D shear wave (S-Wave) velocity profiles. The superposition of all the local 1D S-Wave velocity profiles can potentially lead to a pseudo-3D (or pseudo-2D) velocity model for the subsurface structure. In order to study the capability of the ambient noise array tomography method to provide reliable geophysical ground models on geotechnical scales in urban environments, a relative small circular array (radius of 500m approximately) incorporating 34 recording stations was installed inside the city of Thessaloniki (Northern Greece). The study area corresponds to the boundary between the geological bedrock and Quaternary/Neogene sediments, with the gneiss bedrock showing a gradual thickness increase from its NE outcrop towards the SW, to the coastline of the city. Large-scale studies in the broader Thessaloniki area (e.g. Anastasiadis et al. 2001, Panou et al. 2005) have showed that the bedrock exhibits a more or less 2D structure in the study area, gradually dipping towards the coastline realizing depths possibly exceeding 200m.

    Fahlore-group minerals in Oligocene magmatic-hydrothermal deposits from the central and eastern Rhodope area, Bulgaria and Greece (e.g. porphyry-epithermal systems at Pagoni Rachi, Maronia and Kassiteres-Sapes, polymetallic epithermal high- and intermediate-sulfidation veins at Kirki, Perama Hill, Mavrokoryfi, Pefka, Zvezdel-Pcheloyad and Madzharovo, skarn-carbonate replacement deposits at Laki, Davidkovo, Madan, Enyovche and intrusion-related deposits at Kimmeria), cover the whole range of the tetrahedrite-tennantite solid solution series and are dominated by zincian and ferroan varieties reflecting deposition from Zn-(and Fe)-rich fluids. The majority of the studied fahlores are "normal" fully-substituted with Cu (+Ag) close to 10 apfu. However, high-sulfidation epithermal deposits in Greece contain "Cu-excess" tetrahedrite-tennantite; those with extreme high Cu-excess > Fe + Zn occur in transitional high- to intermediate-sulfidation systems, whereas low "Cu-excess" tetrahedrite-tennantite with Zn > Cu-excess + Fe and Fe > Cu-excess + Zn are part of tellurides-bearing intermediate-sulfidation assemblages. The epithermal St. Demetrios and Pefka deposits display the most Cu-rich tetrahedrites (11.039 apfu Cu) and tennantite (11.784 apfu Cu) worldwide. Although Ag substitutes for Cu in the structure of Ag-rich tetrahedrite in several deposits, freibergite with 6.800 apfu Ag occurs only at Mavrokoryfi; in particular, the cadmian freibergite at Mavrokoryfi is the second finding of this variety worldwide. Tellurium-bearing fahlore varieties occur in association with enargite/luzonite and native gold in high-sulfidation ore assemblages. Tetravalent tellurium substitutes for trivalent As and Sb in goldfieldite and Te-rich tennantite and tetrahedrite at Mavrokoryfi, Perama Hill, St. Demetrios and Pefka deposits. Goldfieldite at Mavrokoryfi and Perama Hill is remarkably Te-rich (up to 3.766 apfu and 3.711 apfu Te, respectively), with total metal content of 10.591 apfu and

    Detrital zircon U-Pb ages of a quartzite from the Feneos locality of Peloponnesus, S. Greece, were determined by LA-ICPMS. The rock classifies as a mature quartz arenite and belongs to an original shale-sandstone succession now metamorphosed into a phyllite-quartzite unit. The latter chiefly represents the External Blueschist Belt of the Hellenides widely known as the Arna or Phyllite - Quartzite (PQ) Unit. Zircon age clusters at 0.5-0.75, 0.85, 0.95-1.1, 1.75-2 and 2.4-3 Ga point at the Saharan Metacraton and the Transgondwanan Supermountain as contributing sources; the youngest concordant grain is 522 Ma old. Based on great similarities in lithology, zircon age-distribution patterns and depositional setting between the Feneos quartzite and intact Cambro-Ordovician sandstone-shale sequences of Libya (Murzuq and Kufrah basins) we propose that the protolith of the former was deposited in an epeiric sea north of Libya during the Cambro-Ordovician. Feneos, as part of the Cimmerian block, had become detached from the NE Gondwanan margin during Late Carboniferous - Early Permian times and drifted northward. In central Crete, similar-looking sequences (Galinos beds) were originally deposited in an accretionary/fore-arc complex outboard of the south Laurussian active margin (Pelagonia) between ~297-230 Ma. The southern Pelagonian margin eventually collided (mild docking) with the northward drifting Cimmerian block signaling the closure of Palaeotethys by early Late Triassic. The Gondwanan affinity of the Feneos quartzite strongly contrasts the European one of the Galinos beds; the suture of Palaeotethys can thus be traced in S. Greece within the pre-Triassic sedimentary sequences of Peloponnesus and Crete. In the eastern Mediterranean realm, rocks with similar age clusters crop out in Greece (Peloponnesus, this study; eastern Crete, Sfaka locality; north-central Macedonia, Vertiskos terrane), NW Turkey (central Sakarya terrane), Libya (Murzuq and Kufrah basins), Israel

    A prospective molecular epidemiology study of HIV-1 infection was conducted in newly diagnosed and antiretroviral-naive patients in Northern Greece between 2009 and 2010 using a predefined enrolling strategy. Phylogenetic trees of the pol sequences obtained in this study with reference sequences indicated that subtypes B and A1 were the most common subtypes present and accounted for 44.9% and 42.9%, respectively, followed by subtype C (3.1%), CRF02_AG (4.1%), CRF04_cpx (2.0%), and subtypes CRF01_01, F1, and G (1.0%). A high rate of clustered transmission of subtype A1-resistant strains to reverse transcriptase (RT) inhibitors was observed among men having sex with men. Indeed, 15 out of 17 study subjects (88.2%) infected with transmitted drug resistance (TDR) strains were implicated in transmission clusters, 10 of whom (66.7%) were men who have sex with men (MSM), and were also infected with subsubtype A1 strains. The main cluster within subtype A1 (I) included eight men reporting having sex with men from Thessaloniki infected with dual-class RT-resistant strains carrying both T215C and Y181C mutations.

    2011-06-01

    The results of a systematic investigation and recording of tornado and waterspout occurrence in Greece for the 10-year period 2000-2009 are presented. This is the first database developed in Greece in an attempt to collect and record comprehensive information about tornadoes, waterspouts, funnel clouds, dust devils and other whirlwind phenomena. The primary research purpose of this database is to search, diagnose and record tornado and waterspout occurrences and identify their morphological and climatological features. Based on the 10-year data, a mean annual number of 1.1 tornadoes per unit area of 10 4 km 2, is depicted for Greece. The seasonality appears differently for various parts, with winter most active tornado season for western Greece and summer for northern Greece. Spatial distribution showed that tornadoes are more frequent over western Greece and the Ionian coasts with a local maximum over northwest Peloponnese. Waterspouts occur in both the Aegean and the Ionian Sea mostly in summer and autumn, with a peak in September, while a considerable geographical maximum is located over north off the shore of Iraklion, Crete Island. A preliminary estimate of probability of tornado occurrence for each of the 51 Greek prefectures plus the Mount Athos area, showed highest values for Kerkyra Island and Elias prefectures, western Greece. Analysis based on intensities as assessed by damage data, indicated that the majority of tornadoes reached T4 of the T-scale or F2 of the F-scale. Short wave trough is found as the most relevant synoptic circulation pattern to tornadic activity. Thermodynamic and wind parameters showed a wide range of values, suggesting that threat levels should be adjusted for various areas since tornadoes and waterspouts can occur in different environments.

    During spring and summer 1978, Macedonia (Greece) suffered damaging seismic activity. During the two main shocks which occurred on May 23 (Mb = 5.7) and June 20 (Mb = 6.1), seismic open cracks and faults were formed in the epicentral area, 25 km NNE from Thessaloniki. They have been mapped and their kinematics analyzed. These studies have shown that they result from the reactivation of existing faults of Pleistocene, Recent, and historical age and that the crust is stretching along a N-S to NNE-SSW direction in that part of the North Aegean. Principal stress directions have been computed from the slip vectors measured on recent neotectonic faults and seismic cracks and faults, this computation utilizing a simple mechanical model (homogeneous deformation through the addition of small and independent displacements of rigid blocks in a highly fractured body). A striking feature of this analysis is that the tensional directions σ3 deduced from seismic faulting and from recent neotectonic faulting are nearly the same. They are compatible with the regional tension axis deduced from focal mechanisms of North Aegean and with the focal mechanisms of the 1978 Thessaloniki main shocks. They are also compatible with in situ stress measurements in this region. Studies of superficial seismic faulting strongly support previous assumptions proposed from aftershock distribution: the 1978 Thessaloniki earthquakes resulted from reactivation of several different faults situated within the same NE dipping fault zone of Upper Eocene-Lower Oligocene age (and older) separating the Serbo-Macedonian Massif from the Peonias (East Vardar) zone.

    Greenhouse and laboratory studies were conducted to evaluate feeding activity and superficial damage to soybean seed by the brown-winged stink bug, Edessa meditabunda (F.), and the Neotropical brown stink bug, Euschistus heros (F.). Soybean plants (cv. BRS 282), at R6 stage of development were used. Thirty pairs of each species were used individually for 48 h. Two daily observations (9:00 AM and 3:00 PM) were taken to record the number of bugs (feeding/resting) on plant parts. Harvested seeds imbibed in tetrazolium solution were photographed for measurement of the damaged surface. Adult E. meditabunda significantly preferred soybean stems (19.7 bugs) to pods (2.7). Feeding/resting was similar at 9:00 AM (mean number of 28.0 bugs) and 3:00 PM (24.3). Euschistus heros equally fed/stayed on stems (7.3 bugs) and pods (6.9), although most bugs (12.3) remained on the cage net; feeding/resting on all plant structures amounted to 13.7 bugs at 9:00 AM and 17.7 bugs at 3:00 PM. Amylase activity was greater for E. heros (41.61 ± 0.89 U/mg) and almost none for E. meditabunda (2.35 ± 0.14 U/mg). The superficial damage to seeds was significantly greater for E. meditabunda (22. 9 mm(2)) compared to E. heros (12.5 mm(2)). However, E. meditabunda caused less shrinkage of the seed tegument, while E. heros damage was deeper and seeds showed reduction in size. PMID:23950088

    The development and application of an analytical methodology for the pretreatment and determination of 253 multiclass pesticides, in lake sediment samples, using liquid chromatography coupled with mass spectrometry (LC-MS/MS) are described in this work. Sediments of lakes Volvi, Doirani, and Kerkini, located in northern Greece, were collected in two-time periods (fall/winter 2010 and spring/summer 2011) and analyzed, applying the developed analytical methodology. Microwave-assisted extraction (MAE) was applied to extract the pesticide residues from lake sediment samples. Analytical results were stored, categorized, and visualized using geographical information systems, in order to assess and observe spatial and temporal variations of the pollution. Main pesticides that were detected included the following: amitrole, tebuconazole, phoxim, diniconazole, sethoxydim, temephos, tetrachlorvinphos, pendimethalin, boscalid, disulfoton sulfone, lenacil, propiconazole, cycloxydim, pyridaben, and terbuthylazine. Amitrole, diniconazole, and tebuconazole were found to be common in all three lakes. Lakes Kerkini and Doirani exhibited increased concentrations during the first sampling period (winter 2010) with predominant pesticide classes, triazines/triazoles and organophosphates. Pollution is mainly located near the populated villages of the lakes and the nearby cultivations. During the second sampling period, pesticide concentrations appear lower and located in sediments near the center of the lake. Lake Volvi exhibits increased pesticide concentrations during the second sampling period, temporal and spatial variations and different pesticide profile pattern. Increased pollution occurs near the center of the lake during the first sampling period, mainly comprised by triazines/triazoles and organophosphates. During the second sampling period, the majority of the sediment samples demonstrated a different pesticide profile dominated by unclassified pesticides and triazines

    The present work describes the application of an analytical procedure, utilizing ultra performance liquid chromatography (UPLC) coupled with mass spectrometry instrumentation, for the determination of 253 multiclass pesticides, classified in six different groups. Solid phase extraction was applied for the isolation and pre-concentration of target compounds in water samples. Surface waters of the lakes located in Northern Greece (Volvi, Doirani, and Kerkini), were collected in two time periods (fall/winter 2010 and spring/summer 2011) and analyzed, applying the developed analytical methods. Spatial distribution of detected pesticides was visualized using interpolation methods and geographical information systems (GIS). Pesticides with maximum concentrations were amitrole, propoxur, simazine, chlorpyrifos, carbendazim, triazophos, disulfoton-sulfone, pyridaben, sebuthylazine, terbuthylazine, atrazine, atrazine-desethyl, bensulfuron-methyl, metobromuron, metribuzin, rotenone, pyriproxyfen, and rimsulfuron. In Lake Kerkini, mainly carbamates and triazines were determined at elevated concentrations, near the coastal point of the NW side of the lake. Seasonal variations were strong among the applied pesticide classes and determined concentrations, indicating the contribution of pesticide application patterns and rainfall. Lake Doirani exhibited organophosphate pesticides at higher concentrations mainly at coastal points, while triazines emerged as the main pollutant during spring sampling. Lake Volvi exhibited the highest pesticide concentrations, mostly triazines and ureas at the central part of the lake. The occurrence of extreme values and nonconstant seasonal variations indicated that the concentrations were increased disproportionately during the second sampling, as a result of the varying contribution of pollution sources right after the application period. In all cases, the total concentration of pesticides increased during the second sampling period. PMID

  19. Adakitic magmatism in post-collisional setting: An example from the Early-Middle Eocene Magmatic Belt in Southern Bulgaria and Northern Greece

    Post-collisional (56.0-40.4 Ma) adakitic magmatism in the Rhodope Massif and the Kraishte region, including W. Srednogorie, in South Bulgaria followed the collision of the Rhodope and Pelagonian Massifs. It forms a 250 km NW trending belt which continues into the 1000 km long belt of Eocene magmatism in northern Turkey and Iran. The rocks are represented by felsic subvolcanic dykes and sills in the Kraishte and plutons in the Rhodopes. Here, we synthesize new chemical (whole-rock major and trace elements, and Sr and Nd isotopes) and LA-ICP/MS mineral and U-Pb zircon age data along with published similar data in order to constrain the genesis of this magmatism and the early Cenozoic geodynamic evolution of the central Balkan Peninsula. The rocks display typical subduction-related characteristics with enrichment in LILE and LREE and depletion in HFSE (Nb, Ta and Ti). In the Kraishte and western Srednogorie Zones these are calc-alkaline to high-K calc-alkaline rhyolites, displaying a typical adakitic signature, i.e. high La/Yb and Sr/Y ratios. The studied Rhodope Massif rocks are predominantly high-K calc-alkaline and subordinate calc-alkaline granites and granodiorites with a minor amount of tonalites. Petrographically, they are H2O- and accessory-rich (allanite, epidote, titanite, apatite) rocks, showing geochemical affinities from non-adakitic tonalites and mafic granodiorites to adakitic granodiorites and granites. Similarity of Sr and Nd isotopic compositions of the Kraishte subvolcanic and Rhodope intrusive adakitic rocks with the neighboring and coeval NW Anatolian basaltic to dacitic volcanics and plutons suggests that the most likely source for the South Bulgarian adakitic rocks is the subduction-enriched depleted lithospheric mantle. The nearby and contemporaneous East Serbian alkaline basalts are isotopically and compositionally different and, probably, originate from an OIB-like mantle source. Subsequent fractionation within an isotopically similar lower

  20. Timing of igneous accretion, composition, and temporal relation of the Kassandra-Sithonia rift-spreading center within the eastern Vardar suture zone, Northern Greece: insights into Jurassic arc/back-arc systems evolution at the Eurasian plate margin

    2015-10-01

    In the Hellenides of northern Greece, the Kassandra-Sithonia and Central Chalkidiki ophiolites constitute the Vardar suture zone against the Serbo-Macedonian margin of Eurasia. The mafic-intermediate to acid members in the crustal section of the Kassandra-Sithonia ophiolites have N- and E-MORB signatures compatible with an origin in a back-arc spreading center. The MORB mantle source has received subduction zone input from the nearby Paikon arc system as revealed by LILE and LREE enrichments. A diorite from the Gerakini complex presumably belonging to the Central Chalkidiki ophiolites shows more enriched HFSE and REE patterns relative to MORB and Na-rich character compared to the Kassandra-Sithonia ophiolites. The Sithonia ophiolite crystallization spans from 159 to 149 Ma, and the Gerakini complex diorite crystallized at 173 Ma as derived from new U-Pb zircon geochronology. The main cluster of Permo-Carboniferous, a small cluster of Neoproterozoic-Cambrian and few Proterozoic, Ordovician, Devonian, Triassic and Middle Jurassic inherited zircons derive from the Serbo-Macedonian margin units. Thus, a Late Jurassic ca. 10 Ma lasting igneous accretion of the Kassandra-Sithonia back-arc crust within the eastern Vardar zone is now well constrained and corroborated by Berriasian-Early Valanginian supra-ophiolite cover limestones. Instead of an affinity to the Central Chalkidiki ophiolites, the Gerakini diorite exhibits chemical similarity to the Chortiatis arc magmatic suite of the Circum-Rhodope belt within the eastern Vardar zone. The Gerakini diorite predates the Sithonia ophiolite in which the Chortiatis arc suite supplied Middle Jurassic inherited zircons. The Chortiatis arc compared with arc-related Evros ophiolites of the Circum-Rhodope belt in Thrace region shows the same 173-160 Ma life span and tectonic setting, implying the extension of the arc systems across the north Aegean Sea. Based on these new temporal constraints, a tectonic scenario of Jurassic

    2009-01-01

    This paper aims to present an overview of current medical education in Greece. Greece has a centuries-long tradition in practising and teaching medicine. Medical training, although rigorous, is particularly humane. All Medical Schools in Modern Greece are currently, undergoing a series of changes in an effort to modernize training. The medical education system is also getting harmonized to European Standards for Higher Education, relating to Undergraduate, Postgraduate and Continuous Medical Education of doctors. A specific strength of the Greek educational system is its ethos that emphasises good working conditions and excellent support and supervision at all levels. The current overhauls in Higher Education occupy students, academics and the society at large. Political issues, such as accountability, regulation and autonomy of academia are generating debate. The two-cycle, Bachelor-Master, Undergraduate Model, as described in the Bologna Declaration is still to be implemented. Quality control measures are currently introduced in all academic sectors.

  8. Coastal erosion and accretion rates in Greece

    2010-05-01

    Erosion threatens many coastal regions of Greece. Anthropogenic changes of landforms such as coastal roads built on even narrow beaches, sand mining for construction, poor design of coastal structures that interfere with sediment, and dams without sediment bypasses have significantly reduced beach widths. We present erosion rates for different beaches, some of which are in sensitive ecosystems, otherwise "protected" by local and EU ordinances. By comparing inferences of beach widths in varying intervals from 1933 to 2006, we infer that the construction of dams in Acheloos river in western Greece, built in a faraonic attempt to partially divert its flows to eastern Greece, this is responsible for up to 20m/year erosion rates observed in certain locales in the Acheloos delta. More characteristic erosion rates in the region are ~ 2m/year. By contrast, there appears rapid accretion of up to 4m/year in the beaches around the Nestos delta in northern Greece (Papadopoulos, 2009). In beaches that are not near large river deltas, erosion rates range from 0.5m/year to 1m/year. While we have not done comprehensive comparisons among coastlines with different levels of coastal development, it does appear that rapid coastal development correlates well with erosion rates. The underlying problem is the complete lack of any semblance of coastal zone management in Greece and substandard design of coastal structures, which are often sited without any measurements of waves and currents offshore (Synolakis et al, 2008). Beach maintenance remains an exotic concept for most local authorities, who invariably prefer to build hard coastal structures to "protect" versus nourish, siting lack of experience with nourishment and "environmental" concerns. In certain cases, choices are dictated by costs, the larger the cost the easier the project gets approved by regulatory authorities, hence the preference for concrete or rubble structures. We conclude that, unless urgent salvage measures are

    This study aimed at investigating the occurrence of Cryptosporidium spp. in diarrheic goat kids in Greece and the risk factors associated with cryptosporidiosis. Altogether, 292 diarrheic 4–15-day-old goat kids from 54 dairy goat herds of Northern Greece were examined. Oocysts of Cryptosporidium spp. were detected in 223 of 292 (76.4%) goat kids and the intensity of infection was scored as “high” in 142 samples, “moderate” in 45 samples, and “low” in 36 samples. Larger herds (>200 animals) had higher infection rates than smaller ones, although this difference was not statistically significant. Significantly higher infection rates were observed in herds during late kidding season (1 January to 30 April) compared to the early one (1 September to 31 December). These results suggest that cryptosporidiosis is very common in diarrheic goat kids in Greece, especially in large herds during the late parturition season. PMID:26819799

    During the last 35 years, visceral leishmaniasis has spread in Greece with autochthonous human cases appearing in 41 of the 54 prefectures. The occurrence of the disease was mapped and related to dog seropositivity, environmental and geospatial risk factors. Average dog seropositivity was 22.1% and positive animals were found in 43 of 54 prefectures. Factors like: altitude, presence of water bodies, land use, wind speed, mean land surface temperature, mean relative humidity, and mean annual rainfall were found to affect dog seropositivity. Cases of cutaneous leishmaniasis, caused by Leishmania tropica are also increasing. Phlebotomus similis believed to be the potential vector of L. tropica in Greece, was found in areas where the disease is widespread but also where cases have never been reported implying a danger of introduction of this anthroponotic parasite to new regions.

Clockwise from left, the mountains of Greece, Albania, Macedonia, Yugoslavia, Bulgaria, and Turkey are swathed in brilliant greens and shades of golden brown; meanwhile (counterclockwise from left) the Ionian, Mediterranean, Aegean, and Black Seas are beautifully blue and green.Running diagonally across the image from the bottom middle to the top right is a gray streak that is caused by the angle of reflection of the sun on the water (called sun glint). The darker areas within this gray swath denote calmer water, and make visible currents that would not otherwise be noticeable.Surprisingly few fires were burning hot enough to be detectable by MODIS when this image was acquired during the height of the summer dry season. A single fire is visible burning in mainland Greece, six are visible in northwestern Turkey, and one burns on the western coast (marked with red outlines).

    Argiriou, Athanassios A.; Lykoudis, Spyros

    2006-08-01

    SummaryThe contribution of stable isotopes in meteorological, climatological and hydrological research is well known. Until this date and despite the fact that several hydrological studies of water sources in Greece have been published, no systematic isotopic study of precipitation has been performed in the country. This paper presents all the available isotopic data collected since 1960 in several Hellenic measurement stations. This data is divided in two periods: the first covers data that was collected in the past, in the frame of a preliminary survey of the isotope composition of precipitation in the Eastern Mediterranean Sea and specific hydrological studies; the second is the result of a three-year coordinated research project of the International Atomic Energy Agency, in which the authors participated, aiming at the systematic study of stable isotopes ( 2H and 18O) and 3H in precipitation around the Mediterranean basin. No statistically significant behavior between the two periods of data was found. The isotopic content of precipitation presents characteristics intermediate of those of the Eastern and Western Mediterranean. The tritium concentration in precipitation declines as expected towards the pre-bomb levels, however there is an indication that tritium concentrations are higher in Northern Greece.

  13. Twins in Ancient Greece: a synopsis.

    PubMed

    Malamitsi-Puchner, Ariadne

    2016-01-01

    This brief outline associates twins with several aspects of life in Ancient Greece. In Greek mythology twins caused ambivalent reactions and were believed to have ambivalent feelings for each other. Very often, they were viewed as the representatives of the dualistic nature of the universe. Heteropaternal superfecundation, which dominates in ancient myths, explains on one hand, the god-like qualities and, on the other hand, the mortal nature of many twins. An assumption is presented that legends referring to twins might reflect the territorial expansions of Ancient Greeks in Northern Mediterranean, around the Black Sea, in Asia Minor, as well as North East Africa. In conclusion, in Greek antiquity, twins have been used as transitional figures between myth and reality. PMID:26135766

    The last major fire in southern Greece was brought under control this weekend, but not until over 469,000 acres of mostly forest and farmland were destroyed. An estimated 4000 people lost their homes, and over 60 deaths were reported. These were the worst fires ever to occur in Greece. In this Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image acquired September 4 over the western coast of the Peloponnesus Peninsula, burned areas appear in dark red, and unburned vegetation is green. The area includes the ancient site of Olympia, the site of the Olympic Games in classical times. The fires came within 2 kilometers (1.2 miles) of the archaeological site, but spared it.

    With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

    2014-09-01

    Tornadoes have been reported in Greece during the last few decades and recent studies have given evidence that western Greece is an area vulnerable to tornadoes, waterspouts and funnel clouds In this study, the composite means and anomalies of synoptic conditions for tornadic events (tornadoes, waterspouts and funnel clouds) over western Greece are analyzed and discussed. The daily composite means of synoptic conditions were based on the National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) reanalysis data sets, for the period 12 August 1953 to 31 December 2012. The daily composite anomalies were calculated with respect to 30 years of climatological study (1981-2010) of the synoptic conditions. The analysis was carried out in terms of seasonal and monthly variability of composite means and anomalies of synoptic conditions for specific isobaric levels of 500, 700, 850, 925 hPa and the sea level pressure (SLP). In addition, an analysis and discussion about the dynamic lifted index from NCEP-NCAR reanalysis data sets is presented. The daily composite mean analysis of 500 hPa revealed a trough line across the northern Adriatic Sea and central Italy, associated with a SW upper-air stream over western Greece. The maximum composite anomalies were depicted at the isobaric level of 500 hPa during autumn, spring and summer, against winter when the anomaly appeared at 925 hPa isobaric level. In addition, 48% of tornado events during the autumn season occurred in pre-frontal weather conditions (cold fronts) and 27% developed after the passage of the cold front. Furthermore, the main difference in synoptic patterns between tornado and waterspout days along western Greece during the autumn season is the maximum daily composite anomaly over the Gulf of Taranto.

    Culicoides biting midges (Diptera: Ceratopogonidae) were trapped between 1999 and 2004 at 122 locations in mainland Greece and on most of the larger Aegean and Ionian islands, using OVI light traps, in order to determine the distribution and seasonal activity of bluetongue virus vectors and other Culicoides species. Thirty-nine Culicoides species were identified, six of which (C. furcillatus, C. impunctatus, C. paolae, C. pictipennis, C. riethi, and C. scoticus) were identified for the first time in Greece. Two of these (C. impunctatus and C. scoticus) may be of veterinary importance due to their role as vectors of bluetongue virus and related orbiviruses. In addition, C. imicola was detected for the first time in mainland Greece. PMID:20836829

    The Isthmus of Corinth has played a very important role in the history of Greece. It is the only land bridge between the country's north (Attica) and south (Peloponnese). It is a 6 km wide tongue of land separating the Gulf of Corinth from the Saronic Sea. Populations, armies and commodities have got to move through it. In the 6th century BCE, the Greeks built the Diolkos, a 10 meter-wide stone roadway to pull ships across the Isthmus on wooden cylinders and wheeled vehicles. In 1882, a canal was started and completed 11 years later. It is 6343 meters long, 25 meters wide, and 8 meters deep.

  20. Stratigraphy and tectonics of a time-transgressive ophiolite obduction onto the eastern margin of the Pelagonian platform from Late Bathonian until Valanginian time, exemplified in northern Evvoia, Greece

    Scherreiks, Rudolph; Meléndez, Guillermo; BouDagher-Fadel, Marcelle; Fermeli, Georgia; Bosence, Dan

    2014-11-01

    The obduction of an ophiolite sheet onto the eastern Pelagonian carbonate platform complex of the Hellenides began during the Late Bathonian and ended with the final emplacement of the ophiolite during Valanginian time. The early stages of obduction caused subaerial exposure of the platform, recorded by an unconformity of Callovian age, which is marked by laterites overlying folded and faulted, karstic substrates. The laterites have distinct ophiolitic geochemical signatures, indicating that emergent ophiolite had been undergoing lateritic weathering. This unconformity coincides with widespread western Tethyan, Callovian gaps, indicating that the obduction in the Hellenides was probably related to far-reaching plate tectonic processes. Resumed gravitational pull and rollback of the subducted, oceanic leading edge of the temporarily exposed ophiolite. Platform drowning continued into Tithonian-Valanginian time, documented initially by reefal carbonates and then by below-CCD, carbonate-free radiolarian cherts and shales. Subsequently, siliciclastic turbidites, which apparently originated from uplifted Variscan basement, were deposited together with and over the radiolarite as the ophiolite nappe sheet advanced. The nappe substrate underwent tectonic deformations of varying intensity, while polymictic mélange and syntectonic sedimentary debris accreted beneath the ophiolite and at the nappe front. The provenience of the ophiolite nappe complexes of northern Evvoia most probably has to be looked for in the Vardar ocean.

    1993-10-01

    An assessment of the radiological consequences that would result for the population of Greece from postulated major nuclear accidents in the Kozloduy nuclear power station in Bulgaria is performed. Kozloduy lies at a distance of 225 km from the northern borders of Greece and contains six reactors, all of the Russian WWER type. The postulated accidents that are classified as level 7 accidents on the International Nuclear Event Scale, involve significant releases of radioactive materials into the environment, and widespread health and environmental effects. The analysis is performed by the MACCS code. The estimated consequences are compared to the corresponding actual impact of the Chernobyl accident in Greece. The results of the analysis indicate that, under the conservative assumptions adopted, the radiological consequences of the most severe accidents considered would be about 1.5 orders of magnitude larger than the actual radiological consequences of the Chernobyl accident.

    In order to present the social, scientific and institutional context which permitted the use of leucotomies in Greece, we have reviewed the Archives of the Medical Associations, the medical literature of the years 1946-56, a reader's dissertation and the memoirs of two psychiatrists. More than 250 leucotomies were done in the two public psychiatric hospitals in Athens from 1947 to 1954, as well as 40 leucotomies in the public psychiatric hospital in Thessaloniki. Although aware of the side effects, psychiatrists justified the use of the procedure. The performance of leucotomies in Greece declined because of reports of the dangers of the operation and its unpredictable outcome for the patients, but mainly because of the encouraging results with psychotropic drugs in the early 1950s.

  5. Features of criticality in precursory seismic electric signals and earthquakes in Greece

    NASA Astrophysics Data System (ADS)

    Dologlou, E.

    2013-06-01

    Very recently the recordings of precursory seismic electric signals (SESsf) in the island of Kozu-shima, Japan, have been reported, and their interrelation with subsequent earthquakes was shown to be beyond chance. Almost simultaneously, the recording of SES activity in northern Greece was also reported, which was followed by a magnitude 5.7 earthquake in northern Greece. These facts strengthen the aspects on the precursory nature of SESs and also enable the updating of a previously found power law relation between the earthquake stress drop and the lead time of SESs. They led to an exponent of 0.330, which falls in the range of critical exponents for fracture. The stability of this exponent, which results from a large amount of data during the last 30 yr, is remarkable and may thus confirm features of criticality in the pre-seismic region after the SES emission. The underlying physics are also discussed.

The cost of blood transfusion is rising in Greece and amounts to nearly 15 billion drachmas per year due to the constant increase in demand and consequently, the price of each unit of blood. The production and distribution of blood on national scale involves meeting the demand for 500.000 units. Blood is mostly given by the friends and relatives of patients (55%) and by voluntary blood donation (30%). Approximately 50% of the blood produced is used in surgery, 20% for cases of beta-thalassaemia, 10% for emergencies and 20% for internal medicine cases. The blood transfusion system is totally funded by the state budget and the value to users is free of charge. The way in which blood is collected and processed differs from one geographical area to another and the unit cost depends on the size of the department concerned, ranging from 60-150 $. The need to control costs and restrain expenditure, in conjunction with guarantees of sufficiency and quality, makes it essential that measures should be taken to introduce economies of scale and encourage competition among blood providers, for increased production, components preparation and rational usage of blood. The introduction of a costing policy becomes necessary in this effort to achieve cost-containment techniques. PMID:8581182

    Precipitation regime over Greece is controlled by the atmospheric circulation, orography sea surface temperature distribution and land/sea interaction. Previous studies have shown that the precipitation amounts are increased in Western Greece, which is located in the upstream side of the largest mountain range of the central mainland. Furthermore, the longest dry spells were identified in south eastern part of Greece during summer and in northern Greek area during winter. The objective of this study is to investigate the impact of topography on prolonged dry periods over Greece, using the third generation hydrostatic Regional Climate Model RegCM3, which shows a noticeable improvement in the representation of the surface hydrological cycle in mountainous regions. More specifically, an attempt is made to study the distribution of prolonged dry spells during two seasons, summer of 1993 and winter of 1989, over the Greek area, under two different simulation scenarios: the first employs the real orography of the Greek area while in the second one the orography is eliminated, by transforming the models terrain code. Both simulation experiments were conducted with the high spatial resolution of 10 Km, while the MIT-Emanuel Convective Precipitation Scheme was selected for the computation of convective precipitation, as it offers more physical representation of convection compared to the other oldest schemes of RegCM. The model was firstly validated through comparisons of the model outputs with observed precipitation amount data, employing 20 stations over Greece for the two selected seasons. The validation demonstrated that the model can simulate precipitation amount quite well over the Greek area, except for the south Dodecanese Islands, where precipitation is underestimated, and the eastern continental Greece, where the daily precipitation is overestimated. For the identification of the extreme dry spells, the climatic index CDD (Maximum number of consecutive dry days

    The goal of this study is the assessment of the reliability of the TRMM (Tropical Rainfall Measuring Mission) 3B-43 gridded precipitation estimates over Greece. The evaluation was made using gridded precipitation data based on data from meteorological stations for the wider region of Greece. The TRMM gridded estimates are on a calendar month temporal resolution and 0.25°×0.25° spatial resolution concerning the 11-year period 1998-2008. In order to compare directly the TRMM with the observational data, the data from the meteorological stations (~70 stations) were upscaled exactly to the same resolution as the TRMM data, using Kriging spatial interpolation method, taking into account the altitude of the meteorological stations. The annual and seasonal spatial distribution of the differences between the two datasets along with the spatial distribution of the correlation coefficients are presented and analyzed. The TRMM gridded data due to their high spatial resolution, perform quite well the spatial distribution of precipitation in Greece and especially the orographic precipitation over the Pindus mountainous area. The spatial distribution of correlations between the two different gridded bases is quite high (correlation coefficient > 0.8) for the entire Greek territory with minor exceptions over mountainous continental areas, which is very likely due to the lack of data from high altitude stations. The TRMM gridded data overestimate the precipitation (> 50mm) mostly during the winter, spring and autumn, especially in the region of the Aegean Sea and the coasts of Asia Minor, and underestimate the precipitation over central highlands (Pindus Mt.) and northern areas (all seasons), over southern Ionian Sea and the Crete Island (winter). Additionally, high positive anomalies (> 50mm) appear during autumn over Ionian Sea and Peloponnese, while the summer is generally characterized by small anomalies.

    Since the double disaster of the 9.0 magnitude earthquake and tsunami that affected hundreds of thousands of people and seriously damaged the Fukushima Daichi power plant in Japan on 11 March 2011, traces of radioactive emissions from Fukushima have spread across the entire northern hemisphere. The radioactive isotope of iodine (131)I that was generated by the nuclear accident in Fukushima arrived in Greece on 24 March 2011. Radioactive iodine is present in the air either as gas or bound to particles (aerosols). The maximum (131)I concentrations were measured between 3 and 5 April 2011. In aerosols the maximum (131)I values measured in Southern Greece (Athens) and Northern Greece (Thessaloniki) were 585±70 and 408±61 μΒq m(-3), respectively. (131)I concentrations in gas were about 3.5 times higher than in aerosols. Since 29 April 2011, the (131)I concentration has been below detection limits. Traces of (137)Cs and (134)Cs were also measured in the air filters with an activity ratio of (137)Cs/(134)Cs equal to 1 and (131)I/(137)Cs activity ratio of about 3. Since 16 May 2011, the (137)Cs concentration in air has been determined to be about the same as before the Fukushima accident. Traces of (131)I were also measured in grass and milk. The maximum measured activity of (131)I in sheep milk was about 2 Bq l(-1) which is 5000 times less than that measured in Greece immediately after the Chernobyl accident. The measured activity concentrations of artificial radionuclides in Greece due to the Fukushima release, have been very low, with no impact on human health. PMID:22090415

    Thirty beach sand samples from the granitic shoreline of the Sithonia Plutonic Complex (SPC) were analyzed for their REE and major element contents. The obtained results are compared with the adjacent SPC rock-types, in order to determine any enrichments or depletions. Among the samples enriched in REE, three are seasonal deposits of heavy minerals and their concentrations are controlled by the action of sea-waves. The available geochemical characteristics were also used to confirm the parental rocks of the beach sands, which are the SPC rock-types. The heavy fractions (total, total magnetic and total non-magnetic) of the beach sands were correlated with the REE concentrations, revealing a strong correlation between the heavy non-magnetic fraction and REE content. Among the minerals of the heavy non-magnetic fraction, monazite seems to control the REE content in the heavy mineral-enriched samples, whereas in the rest of the samples allanite, belonging to the heavy magnetic fraction may be the most important REE mineral.

    Greece has been rabies free since 1987 while no human cases have been seen since 1970. The re-emergence of rabies in Northern Greece during 2012-2013 in wild and domestic animals prompted a systematic review of historical evidence of the presence of the disease in the country from ancient years till the present. Historical data is presented along with efforts to prevent disease in animals and humans especially during the high prevalent periods in the country in the mid-20th century. These efforts serve as a guide to current extensive efforts to prevent spread especially in the wild and domestic animal populations. PMID:25459432

    Zeolites are present in altered pyroclastic rocks at many localities in Greece, and large deposits of potential economic interest are present in three areas: (1) the Evros region of the province of Thrace in the north-eastern part of the Greek mainland; (2) the islands of Kimolos and Poliegos in the western Aegean; and (3) the island of Samos in the eastern Aegean Sea. The deposits in Thrace are of Eocene-Oligocene age and are rich in heulandite and/or clinoptilolite. Those of Kimolos and Poliegos are mainly Quaternary and are rich in mordenite. Those of Samos are Miocene, and are rich in clinoptilolite and/or analcime. The deposits in Thrace are believed to have formed in an open hydrological system by the action of meteoric water, and those of the western Aegean islands in a similar way but under conditions of high heat flow, whereas the deposits in Samos were formed in a saline-alkaline lake.

    Wild birds are common hosts of ticks and can transport them for long distances, contributing to the spreading of tick-borne pathogens. The information about ticks on birds and tick-borne pathogens in Greece is limited. The present study aimed to evaluate the prevalence and species of ticks infesting wild resident birds (mostly small passerines) in Greece, and to assess Borrelia and Rickettsia infection in the collected ticks. Detection of Borrelia burgdorferi s.l. was performed by nested PCR targeting the flaB gene. Rickettsia spp. were detected by PCR targeting the gltA and ompA genes. Seven (2 %) out of 403 birds examined in northern Greece in 2013 were infested with 15 ticks, identified as Ixodes frontalis, Ixodes acuminatus, Hyalomma marginatum, Hyalomma aegyptium and Hyalomma sp. All ticks were negative for Borrelia spp. while four of them were positive for rickettsiae (Rickettsia aeschlimannii in H. aegyptium and Rickettsia sp. in I. frontalis, H. aegyptium and H. marginatum). Ixodes acuminatus is reported for the first time in Greece and Sylvia borin is reported as a new host record for I. acuminatus. PMID:26847630

    Mass miniature radiography in 1969 detected a high prevalence of pleural calcification in three villages in northwest Greece. In 1980 a survey of a 15% sample of the population over the age of 10 was carried out with a 80% response rate. Full-size radiographs, ventilatory capacity measurements, and a detailed questionnaire on respiratory symptoms, type of work, and residence were used. Independent classification of the 408 films by two readers using the ILO/UC scheme showed very few small opacities but a very high prevalence of pleural calcification first evident in young adults and rising to 70% in the elderly. The overall prevalence was 34.7% in men and 21.5% in women. A comparison with the 1969 survey showed a progression rate of 5% per annum. In neither sex was there a significant relation of pleural calcification to smoking, ventilatory capacity, nor type of work, though those classified as field croppers had a slightly higher prevalence. There was no obvious evidence of increased lung cancer or mesothelioma in the village. The agent responsible for this apparently benign condition was not identified.

    On 03 March 2014 at 11:09:50 UT the Ground-to-Rocket Electrodynamics-Electrons Correlative Experiment (GREECE) sounding rocket successfully launched from Poker Flat, Alaska . It reached an apogee of approximately 335 km over the native village of Venetie during a dynamic post-midnight auroral event. A wide range of precipitating electrons were measured with the Acute Precipitating Electron Spectrometer (APES) and Medium-energy Electron SPectrometer (MESP), cumulatively covering 300 ev to 200 keV in varying time resolutions. DC to low frequency electric and magnetic fields were measured at the same time and a langmuir probe was also employed. In addition to the on board instrumentation a suite of ground based imagers was deployed under apogee. We used several electron-multiplying charge-coupled devices (EMCCDs) with different filters and field of views imaging along magnetic zenith. This yielded multi-emission line information about the auroral brightness at the magnetic footprint of the rocket critical for our main goal of exploring the correlation of the sheer flows often observed in high resolution imagery during aurora and the in situ signatures of precipitating particles and waves. The instruments used will be discussed in further detail along with preliminary results of an event rich in particle and wave signatures.

    A systematic study was carried out to investigate the distribution of 59 elements in the sediment and soil samples collected from the river Vardar (Republic of Macedonia and Greece) and its major tributaries. The samples were collected from 28 sampling sites. Analyses were performed by inductively coupled plasma-mass spectrometry. R-mode factor analysis (FA) was used to identify and characterise element associations. Seven associations of elements were determined by the method of multivariate statistics. Every factor (Factors 1-3 and 6 and 7 as geogenic and Factors 4 and 5 as anthropogenic associations of elements) are examined and explained separately. The distribution of various elements showed that there is a presence of anthropogenic elements (Ag, Cd, Cu, Ge, Pb, Sn and Zn) introduced in the river sediments and soils from the mining, metallurgical, industrial and agricultural activities in Vardar River Basin, which covers most of the Republic of Macedonia and Central-northern part of Greece.

    Greece is a country with a big variety of climates due to its geographical position, to the many mountain ranges and also to the multifarious and long coastline. The mountainous volumes are of such orientation that influences the distribution of the precipitation, having as a result, Western Greece to present great differentiations from Central and Eastern Greece. The application of harmonic analysis to the annual variability of precipitation is the goal of this study, so that the components, which compose the annual variability, be elicited. For this purpose, the mean monthly precipitation data from 30 meteorological stations of National Meteorological Service were used for the time period 1950-2000. The initial target is to reduce the number of variables and to detect structure in the relationships between variables. The most commonly used technique for this purpose is the application of Factor Analysis to a table having as columns the meteorological stations-variables and rows the monthly mean precipitation, so that 2 main factors were calculated, which explain the 98% of total variability of precipitation in Greece. Factor 1, representing the so-called uniform field and interpreting the most of the total variance, refers in fact to the Mediterranean depressions, affecting mainly the West of Greece and also the East Aegean and the Asia Minor coasts. In the process, the Fourier Analysis was applied to the factor scores extracted from the Factor Analysis, so that 2 harmonic components are resulted, which explain above the 98% of the total variability of each main factor, and are due to different synoptic and thermodynamic processes associated with Greece's precipitation construction. Finally, the calculation of the time of occurrence of the maximum precipitation, for each harmonic component of each one of the two main factors, gives the spatial distribution of appearance of the maximum precipitation in the Hellenic region.

  20. New archaeointensity results from archaeological sites and variation of the geomagnetic field intensity for the last 7 millennia in Greece

    De Marco, E.; Spatharas, V.; Gómez-Paccard, M.; Chauvin, A.; Kondopoulou, D.

    In this study six new intensity determinations are presented, obtained from five well dated archaeological sites, located in northern Greece and in Paros, Cyclades Islands. The fired structures consisted of ceramic and pottery kilns belonging to the Hellenistic, Roman and Byzantine periods. Between 8 and 21 samples of highly fired baked clays, tiles and bricks were taken, homogeneously distributed over the structures. The samples were analysed using the classical Thellier method, providing the past intensities and directions of the geomagnetic field recorded at each site. The intensity values have been corrected for anisotropy of thermal remanent magnetisation and cooling rate effects. Differences in the mean archaeointensities per site ranging from 1% to 11%, before and after TRM anisotropy and cooling rate corrections, were obtained. The new results indicate a decrease of 20% of the geomagnetic field strength in Greece, during the last four centuries BC. In order to compare our results with previously published data, a catalogue of archaeo- and palaeointensity results for the Aegean area has been established, covering the last 7 millennia. It consists of 336 data from Greece, western Turkey and Former Yugoslavia, collected from various authors. Weighting factors have been applied to these data, that then have been treated with a hierarchical Bayesian modelling, and a geomagnetic field intensity variation curve for Greece was constructed. A good agreement is observed when comparing the curve for Greece with the Bulgarian secular variation curve (SVC) for intensity. Satisfactory coincidence is also found with the archaeointensity data from Mesopotamia. Despite the presence of some time gaps, a more precise secular variation intensity curve has been constructed for Greece which, combined with a forthcoming directional SVC, will help for dating purposes.

    The objective of this research is the exploration of seat belt use in Greece and particularly the identification of the parameters affecting seat belt use in Greece. A national field survey was conducted for the analytical recording of seat belt use. A binary logistic regression model was developed, and the impact of each parameter on seat belt use in Greece was quantified. Parameters included in the model concern characteristics of car occupants (gender, age and position in the car), the type of the car and the type of the road network. The data collection revealed that in Greece, the non-use of seat belt on the urban road network was higher than on the national and rural road network and young and older men use seat belts the least. The developed model showed that travelling on a national road is negative for not wearing the seat belt. Finally, the variable with the highest impact on not wearing a seat belt is being a passenger on the back seats. PMID:21452095

    Anticyclones are often associated with extreme phenomena, like prolonged droughts or heatwaves and, thus, they can significantly impact fauna and flora, water resources and public health. In this study, the association of the summer anticyclonic activity with the joint occurrence of extreme warm and dry conditions over Greece is explored. The warm and dry extreme conditions are defined by utilizing the Warm/Dry (WD) index for representative meteorological stations from sub-regions of Greece with different climatic features. The WD index is the number of days over a period (here summer) having at the same time mean air temperature > 75th percentile of daily mean temperature and precipitation < 25th percentile of daily precipitation amounts. The anticyclonic activity is determined by the density of the anticyclonic systems over the greater Mediterranean region, which, during summer, is maximized over the Balkans and the northern African coast. The anticyclonic system density has resulted from the comprehensive climatology of Mediterranean anticyclones that was assembled with the aid of the finding and tracking scheme of the University of Melbourne (MS scheme), using the ERA-Interim mean sea-level pressure fields for 1979-2012. The examination of inter-annual and spatial variations of the WD index in association with shifts of the anticyclonic maxima shows that the different sub-regions of Greece are not affected evenly, stressing the role of the complex topography of the region and the variations in the subtropical jet position.

    Ticks were collected from various regions of northern Greece and tested for the presence of Crimean-Congo hemorrhagic fever virus (CCHFV) RNA. Human and animal sera were collected in the regions where CCHFV-positive ticks were detected, and they were tested for the presence of IgG antibodies against the virus. A CCHFV strain was detected in Rhipicephalus bursa ticks collected from sheep in Kastoria regional unit, differing by 9.7% at the nucleotide level from the AP92 strain, which was isolated in 1975 in another region of Greece. Up to date, CCHF cases have not been reported in these regions. The human seroprevalence in the area was estimated at 6%, while IgG-positive sheep was detected in two of the four neighboring farms tested. The circulation of this specific CCHFV lineage in Greece, especially in a region where the seroprevalence is high, together with the lack of human CCHF cases, suggests a probable antigenic, but non- or low-pathogenic character of this lineage. Further studies on these strains will increase our knowledge about the role of AP92-like strains in the CCHF epidemiology, which might be useful for drug and vaccine design. PMID:24953797

    Greece is vulnerable to tsunamis, due to the length of the coastline, its islands and its geographical proximity to the Hellenic Arc, an active subduction zone. Historically, about 10% of all world tsunamis occur in the Mediterranean region. Here we review existing tsunami disaster risk management capabilities in Greece. We analyze capabilities across the disaster management continuum, including prevention, preparedness, response and recovery. Specifically, we focus on issues like legal requirements, stakeholders, hazard mitigation practices, emergency operations plans, public awareness and education, community-based approaches and early-warning systems. Our research is based on a review of existing literature and official documentation, on previous projects, as well as on interviews with civil protection officials in Greece. In terms of tsunami disaster prevention and hazard mitigation, the lack of tsunami inundation maps, except for some areas in Crete, makes it quite difficult to get public support for hazard mitigation practices. Urban and spatial planning tools in Greece allow the planner to take into account hazards and establish buffer zones near hazard areas. However, the application of such ordinances at the local and regional levels is often difficult. Eminent domain is not supported by law and there are no regulatory provisions regarding tax abatement as a disaster prevention tool. Building codes require buildings and other structures to withstand lateral dynamic earthquake loads, but there are no provisions for resistance to impact loading from water born debris Public education about tsunamis has increased during the last half-decade but remains sporadic. In terms of disaster preparedness, Greece does have a National Tsunami Warning Center (NTWC) and is a Member of UNESCO's Tsunami Program for North-eastern Atlantic, the Mediterranean and connected seas (NEAM) region. Several exercises have been organized in the framework of the NEAM Tsunami Warning

    1992-12-01

    In this study wind data were used to determine the monthly and annual variations of the wind at 13 meterological stations in western Greece. An analysis of the available wind data for the Ionian Sea islands and the western coasts of Greece is carried out to ascertain its potential for wind energy development. The effect of the limited number of daily observations available on the accuracy of the mean wind speed and annual wind energy estimates is ascertained. The wind speed and direction distributions are represented with Weibull functions. Besides, a mass-consistent numerical mesoscale model was used to give an overview of the wind prospecting and siting problem, and an example of its use for Corfu (Kerkira), an island in the Ionian Sea, is given. The comparison of the accuracy of the stimulation results versus measured wind at an available site is quite encouraging even though it cannot be conclusive since only one station is available.

The data used are daily precipitation totals recorded at the meteorological station of Ioannina University for the period 1970-2002. 156 days with precipitation totals above 35 mm (5% upper limit) are only considered. It is seen that, a minimum frequency of extreme precipitation events appears in the period 1986-1991, which is characterized by a high positive NAO index. For each of the 156 extreme precipitation days, at first, the mean sea level pressure pattern over Europe is constructed by using 273 grid point values. Using Factor Analysis, the dimensionality of the 156×273 data matrix is reduced to 156×5 (84% of the total variance) and then, Cluster Analysis is applied on the results of Factor Analysis. Thus, the 156 cases are grouped objectively to 11 clusters, revealing the main pressure patterns, which favour extreme precipitation in NW Greece. Seven of the patterns are encountered in winter and autumn, while three of them cover a period from autumn to spring and one appears mainly in summer. In all of them the cause of the extreme precipitation event is a low pressure system centred west of Greece or a low pressure trough extended eastwards or southwards up to Greece. In some cases the depression is so strong and extended that it covers the whole Europe and the Mediterranean. In the single summer pattern, rainfall is caused by an extension of the SW Asia thermal low up to the central Mediterranean.

    The beaches of Greece has been eroding rapidly in the past three decades, at rates, that in some cases, reach 1m/year. We report measurements from Agios Nicolaos, Crete based on beach profiles, historic aerial photos, satellite imagery and eyewitness report. We discuss the findings in the context of antropogenic factors. We correlate our measurements, qualitatively, with different indices and produce a risk map to allow decision makers to prioritize mitigation policies.

    Cutaneous leishmaniasis is a disease endemic in Greece. Cases collected between the years 1975 and 1979 are analyzed from a clinico-epidemiologic point of view. Prevalence is highest in the Ionian islands and Crete. The disease most commonly affects individuals 10 to 20 years of age. The exposed parts of the body are most commonly involved, particularly the face. The period of highest incidence is mid-winter. PMID:7358449

    Summary Objectives This paper aims to present an overview of the medical informatics landscape in Greece, to describe the Greek ehealth background and to highlight the main education and research axes in medical informatics, along with activities, achievements and pitfalls. Methods With respect to research and education, formal and informal sources were investigated and information was collected and presented in a qualitative manner, including also quantitative indicators when possible. Results Greece has adopted and applied medical informatics education in various ways, including undergraduate courses in health sciences schools as well as multidisciplinary postgraduate courses. There is a continuous research effort, and large participation in EU-wide initiatives, in all the spectrum of medical informatics research, with notable scientific contributions, although technology maturation is not without barriers. Wide-scale deployment of eHealth is anticipated in the healthcare system in the near future. While ePrescription deployment has been an important step, ICT for integrated care and telehealth have a lot of room for further deployment. Conclusions Greece is a valuable contributor in the European medical informatics arena, and has the potential to offer more as long as the barriers of research and innovation fragmentation are addressed and alleviated.

    Since 2009, when severe fever with thrombocytopenia syndrome virus and Heartland virus have been identified and associated with disease in humans, the interest on tick-borne phleboviruses is increasing rapidly. The aim of the present study was to investigate the presence of tick-borne phleboviruses in Greece and compare them with respective ones detected worldwide. Ticks collected from goats and sheep in 60 sites of 13 regional units of Greece were grouped in pools (1-3 ticks per pool) and tested for the presence of phleboviral RNA. Six of 210 pools were positive; they consisted of Rhipicephalus sanguineus ticks collected from sheep in 3 regional units of Greece: Pella (2/30, 6.7%), Imathia (2/21, 9.5%), and Ioannina (2/28, 7.1%). The overall tick minimum infection rate was 2.1%. The sequences of the Greek phlebovirus (provisionally named Antigone virus) form a distinct clade in the tick-borne phleboviruses, differing by >40% from the currently known phleboviruses. Any probable implication of these viruses to public health remains to be elucidated. PMID:26935112

    In the framework of the project DAPHNE (www.daphne-meteo.gr), the non-hydrostatic Weather Research and Forecasting model with the Advanced Research dynamic solver (WRF-ARW, version 3.5.1) is used to produce very high spatiotemporal resolution simulations of the convective activity over Thessaly plain and hence, enhancing our knowledge on the impact of high resolution elevation and land use data in the moist convection. The expecting results act as a precursor for the potential applicability of a planned precipitation enhancement program. The three model domains, covering Europe, the Mediterranean Sea and northern Africa (d01), the wider area of Greece (d02) and Thessaly region-central Greece (d03), are used at horizontal grid-spacings of 15km, 5km and 1km respectively. ECMWF operational analyses at 6-hourly intervals (0.25ox0.25o lat.-long.) are imported as initial and boundary conditions of the coarse domain, while in the vertical, 39 sigma levels (up to 50 hPa) are used, with increased resolution in the boundary layer. Microphysical processes are represented by WSM6 scheme, sub-grid scale convection by Kain-Fritsch scheme, longwave and shortwave radiation by RRTMG scheme, surface layer by Monin-Obukhov (MM5), boundary layer by Yonsei University and soil physics by NOAH Unified model. Six representative days with different upper-air synoptic circulation types are selected, while high resolution (3'') elevation data from the Shuttle Radar Topography Mission (SRTM - version 4) are inserted in the innermost domain (d03), along with the Corine Land Cover 2000 raster data (3''x3''). The aforementioned data sets are used in different configurations, in order to evaluate the impact of each one on the simulated convective activity in the vicinity of Thessaly region, using a grid of available meteorological stations in the area. For each selected day, four (4) sensitivity simulations are performed, setting a total number of 24 runs. Finally, the best configuration provides

    Cloud-to-ground (CG) lightning activity recorded by the Hellenic National Meteorological Service (HNMS) Precision Lightning Network (PLN) is analysed over the wider area of Greece. In addition, the spatial and temporal relationships between TRMM 3B42 (Tropical Rainfall Measuring Mission) datasets and lightning are presented. The analyses concern the period from January 14, 2008 to December 31, 2012. The Laboratory of Climatology and Atmospheric Environment, University of Athens, has established a detailed dataset of lightning impacts over Greece from 1895 to 2013, based on digitized archive editions of newspapers. The mean seasonal variability of CG lightning activity revealed autumn as the most dominant season with 303 LD, while the mean monthly variability of CG indicated October as the most lightning active month and May as the month with a mean of 27 LD. The mean annual spatial distribution of CG lightning per km2, depicted the maximum frequency over Pindus mountain range (> 7 CG/km2). During the autumn season, the northern Ionian Sea experienced a mean frequency of more than 5 CG/km2, compared to the southern Ionian Sea and NW Peloponnesus, where values of more than 7 CG/km2 are depicted. During the summer season, the maximum frequency appeared along Pindus mountain range, around Attica, Thessaly and central Macedonia highlands. The spatial distribution of seasonal correlations between the number of CG flashes/day and gridded (TRMM 3B42) daily rainfall totals for the period 2008-2012 over Greece, indicated that correlations were mainly positive all over the under study area, within all seasons, and especially during summer and autumn. Regarding the lightning impacts in Greece, based on the 1895-2013 study period, more than 343 fatalities and at least 224 injured people have been recorded. The spatial analysis of lightning impacts, showed that the majority of events has been recorded over Greek mainland and only few scattered events have been reported over

    1990-07-01

    Environmental protection policies generate an equity question concerning the fair allocation of environmental benefits and costs. This paper presents evidence from Greece during the 1980s. The findings reveal that Greek environmental policies, in the form of government self-regulatory programs, are mostly regressive in nature. At the regional level these programs combine all forms of vertical equity. Since the public sector finances the majority of related expenditures out of taxes, the regressive elements of environmental policies have been reinforced by discretionary fiscal measures and tax evasion, accompanied by inflation, which have distorted the country's progressive tax system.

    In the city of Patras (Greece), noise measurements were made for the purposes of determining the present noise-pollution levels and the reaction of the people to them. Noise pollution is ranked second in order after air pollution, and traffic was the principal noise pollutant. The mean noise levels, in 25 monitorig stations throughout the city, were found to be high and definitely unacceptable. For three representative locations, corresponding to high, medium, and low traffic volume, various statistical noise descriptors were used, together with the other measurements, to estimate the noise environment of the entire city.

    Legal capacity of the elderly people in Greece is of great legal, medical and social importance, but has received little attention till now from medical literature. This paper aims to study whether elderly people with dementia are able to participate in legal contracts like sales, purchases, loans, leases, donations and testaments. We tried to introduce a new test for the above legal-financial contracts and show some preliminary findings. The test consists of six examined relevant domains concerning basic monetary skills, cash transactions, bank statement management, financial conceptual knowledge, knowledge of potential heirs (beneficiaries) and assets/estate and finally the decision making process for different dilemmas on sales, purchases, loans, leases, donations and testaments. We studied 203 people. Eighty three people were healthy, 64 with Alzheimer's disease (AD) (10 with severe AD, 22 with moderate, and 32 with mild AD), 10 with Parkinson's disease (PD), and 46 with amnestic Mild Cognitive Impairment (aMCI). Individuals were included in the study only if they were aged 60 and over and only if they had a partner or a guardian who could give information on the individual's daily living. The exclusion criteria were predefined as follows: history of any other mental health disease and/or any other serious somatic health disease except for their official diagnosis of dementia. Results showed statistically significant differences with all three groups of patients characterized as incapable for legal-financial actions. Patients with severe AD (P<0.001), patients with moderate AD (P<0.001), patients with mild AD (P<0.001), patients with PD (P<0.001) and aMCI patients (P<0.001) differed significantly from healthy controls. Further research should include more extensive sampling of elderly patients with varying demographic characteristics in Greece, to confirm and expand our initial findings. In conclusion, our new test which is based on Marson's theoretical model

  5. Late Palaeozoic-Cenozoic assembly of the Tethyan orogen in the light of evidence from Greece and Albania

    Robertson, A. H. F.

    2012-04-01

    The objective here is to use the geology and tectonics of a critical part of the Tethyan orogen, represented by Greece and Albania, to shed light on the tectonic development of Tethys on a regional, to global scale, particularly the history of convergence during Late Palaeozoic to Cenozoic time. For Carboniferous time much evidence suggests that the Korabi-Pelagonian crustal unit as exposed in Albania and Greece formed above a northward-dipping subduction zone along the Eurasia continental margin, with Palaeotethys to the south. However, there is also some evidence of southward subduction beneath Gondwana especially from southern Greece and central southern Turkey. Palaeotethys is inferred to have closed in Europe as far to the east as the longitude of Libya, while remaining open beyond this. There is still uncertainty about the Pangea A-type reconstruction that would restore all of the present units in the area to within the E Mediterranean region, versus the Pangea B-type reconstruction that would require right-lateral displacement of exotic terranes, by up to 3,500 km eastwards. In either reconstruction, fragments of the Variscan collisional orogen are likely to have been displaced eastwards (variable distances) in the Balkan region prior to Late Permian-Early Triassic time. From ~Late Permian, the Greece-Albania crustal units were located in their present relative position within Tethys as a whole. From the mid-Permian, onwards the northern margin of Gondwana was affected by crustal extension. A Mesozoic ocean (Pindos-Mirdita ocean) then rifted during Early-Middle Triassic time, culminating in final continental break-up and seafloor spreading during the Late Triassic (Carnian-Norian). Subduction-influenced volcanics of mainly Early-Middle Triassic age probably reflect the extraction of magma from sub-continental lithosphere that was enriched in subduction-related fluids and volatiles during an earlier, ?Variscan subduction event. The existence of Upper Triassic

    The aim of this research is to investigate the impact of irrigations in the characteristics of convective activity simulated by the non-hydrostatic Weather Research and Forecasting model with the Advanced Research dynamic solver (WRF-ARW, version 3.5.1), under different upper air synoptic conditions in central Greece. To this end, 42 cases equally distributed under the six most frequent upper air synoptic conditions, which are associated with convective activity in the region of interest, were utilized considering two different soil moisture scenarios. In the first scenario, the model was initialized with the surface soil moisture of the ECMWF analysis data that usually does not take into account the modification of soil moisture due to agricultural activity in the area of interest. In the second scenario, the soil moisture in the upper soil layers of the study area was modified to the field capacity for the irrigated cropland. Three model domains, covering Europe, the Mediterranean Sea and northern Africa (d01), the wider area of Greece (d02) and central Greece - Thessaly region (d03) are used at horizontal grid-spacings of 15km, 5km and 1km respectively. The model numerical results indicate a strong dependence of convective spatiotemporal characteristics from the soil moisture difference between the two scenarios.

    The Corinth Rift separates Peloponnesus to the south from main-land Greece to the north. It is one of the most active extensional intra-continental rifts in the world, with geodetically measured rates of extension varying from ~5 mm/yr at the eastern part to ~15 mm/yr at the western part. This work presents a first attempt to study the crustal velocity structure of the western Corinth Rift using ambient noise recordings. We used 3 yrs (01/2012-12/2014) of continuous waveform data recorded at 24 stations from the Corinth Rift Laboratory (CRL) and the Hellenic Unified Seismological Network (HUSN). All available vertical component time-series were cross-correlated to extract Rayleigh wave Green's functions. Group velocity dispersion curves between 0.5 and 7 s period were measured for each station pair by applying frequency-time analysis and then inverted to build group velocity maps of the study area. At the studied periods, the northern coast of the Corinth Rift is generally imaged as a region of elevated seismic velocities compared to the southern coast. More specifically, low velocities are observed in areas of Plio-Quaternary syn-rift sediments such as off-shore regions of the rift, the Mornos delta and a large part of the southern coast. Higher velocities are observed in pre-rift basement structures which are dominated mostly by carbonates. The preliminary results demonstrate good agreement with the major geological features of the area and agree relatively well with previous local earthquake tomography studies. This work will be the base for further investigations towards the study of the Corinth Rift structure using long time-series of ambient noise data.

    The aim of this study was to investigate the bacterial pathogens involved in pediatric urinary tract infections (UTIs) in a tertiary general hospital located in the Thrace province of Northern Greece over a 69-month period (1/2003 to 9/2008), and their antibiotic susceptibility patterns. A total of 622 episodes of UTIs in 508 children were identified. Median age of all children was 16 months (range 1 month to 14 years). Boys were significantly younger than girls (9 months vs. 24 months). Escherichia coli was the most common uropathogen and responsible for 69.1% of UTIs. Approximately half of E. coli isolates were resistant to ampicillin and 20.5% to trimethoprim/sulfamethoxazole (TMP/SMX). E. coli resistance to second-generation and third-generation cephalosporins was <4%, to aminoglycosides <8%, and to nitrofurantoin 4.4%. Pediatric E. coli urine isolates were significantly more resistant to ampicillin and ticarcillin and more sensitive to quinolones compared to adult E. coli uropathogens identified in the same hospital. E. coli resistance to ampicillin and amoxicillin/clavulanic acid was significantly higher in boys 12-23 months-old compared to girls of the same age. In conclusion, nitrofurantoin is a very good choice for chemoprophylaxis. Amoxicillin/clavulanic acid, second-generation cephalosporins, and TMP/SMX are appropriate choices for oral empirical treatment of UTIs. Parenteral aminoglycosides and second and third-generation cephalosporins are excellent treatment choices for inpatient therapy. Finally, sex and age are additional factors that should be taken into account when choosing empirical therapy for children with UTIs. PMID:20524067

    Greece's economic crisis has deepened since it was bailed out by the international community in 2010. The country underwent the sixth consecutive year of economic contraction in 2013, with its economy shrinking by 20% between 2008 and 2012, and anaemic or no growth projected for 2014. Unemployment has more than tripled, from 7·7% in 2008 to 24·3% in 2012, and long-term unemployment reached 14·4%. We review the background to the crisis, assess how austerity measures have affected the health of the Greek population and their access to public health services, and examine the political response to the mounting evidence of a Greek public health tragedy.

    Since 2008 several European countries have fallen into a financial crisis. This crisis has mainly affected the Greek population. The lower of income and the increase of unemployment as consequences of crisis lead to negative effects on people's mental health. Usually, in periods of economic crisis there is an increase of suicidality of population. The aim of this study is to examine the changes of suicide rates in Greece during the last decade (2001-2011) with particular consideration in the recent period of economic crisis (2008-2011). Data regarding the greek general population and the crude data on suicides were obtained from the Hellenic Statistical Authority (ELSTAT). We assessed the specific suicide rate, i.e. the number of suicide cases per 100.000 inhabitants (SSR) using population data on the 2001 and 2011 census. Yearly and mean total, age and sex-SSR were calculated in five years age groups. There were no suicide cases among children under the age of fifteen. We compared total and male, female SSR during the period before the crisis (2001-2007) and during the crisis (2008-2011). During the decade 2001-2011 a total number of 4133 suicide cases were recorded. There were 3423 (82.8%) male suicides and 710 (17.2%) female suicides. During the decade 2001-2011 total SSR increased by 38.4%. In males increased by 33.1% and in females by 69.6%. In the period before the crisis (2001-2007) total SSR decreased by 3.9%. In males decreased by 8.4% but in females increased by 22.3%. During the period of crisis (2008-2011) total SSR increased by 27.2%. In males increased by 26.9% and in females by 28.5%. There was a statistically significant increase in total SSR during the crisis regarding subjects 50-54 years old (t=3.43, p=0.007) and in total SSR of males (t=2.31, p=0.047) as well as of the males age groups 50-54 (t=3.56, p=0.006), 45-49 (t=2.87, p=0.02), 30-34 (t=2.96, p=0.02).

    The last six years the global community is facing an economic crisis that first appeared in USA. This crisis has a lot of impacts especially in health sector. Unemployment, job insecurity and the loss of disposable income have a significant impact in health too. The main objective of this research was to investigate the quality of life of the general population in Greece during the financial crisis. To collect the data it has been used the Greek version of Short Form (36) Health Survey (SF-36v2). In general, income, level of education, cohabitation and parenthood had a significant impact in quality of life. As a conclusion, unemployed participants' score was lower in the entire dimensions and in the two summary scales too. PMID:26152994

    Since the beginning of economic crisis, Greece has been experiencing unprecedented levels of unemployment and profound cuts to public budgets. Health and welfare sectors were subject to severe austerity measures, which have endangered provision of as well as access to services, potentially widening health inequality gap. European Union Statistics on Income and Living Conditions data show that the proportion of individuals on low incomes reporting unmet medical need due to cost doubled from 7 % in 2008 to 13.9 % in 2013, while the relative gap in access to care between the richest and poorest population groups increased almost ten-fold. In addition, austerity cuts have affected other vulnerable groups, such as undocumented migrants and injecting drug users. Steps have been taken in attempt to mitigate the impact of the austerity, however addressing the growing health inequality gap will require persistent effort of the country's leadership for years to come.

    Seventeen Y STR loci were typed in a population sample of 191 unrelated male individuals from Northern Greece. Haplotypes are presented for the following loci: DYS456, DYS389I, DYS390, DYS389II, DYS458, DYS19, DYS385a/b, DYS393, DYS391, DYS439, DYS635, DYS392, Y GATA H4, DYS437, DYS438 and DYS448. The overall haplotype diversity was 0.9992. This database study provides significant additional information for the application of Y-chromosomal STRs to forensic identification efforts in Greece by nearly doubling both the number of individuals and the number of Y-loci typed from Greek populations. These samples have been previously typed for autosomal STRs [L. Kovatsi, T.J. Parsons, R.S. Just, J.A.

    Six widely available satellite precipitation products were extensively validated and intercompared on monthly-to-seasonal timescales and various spatial scales, for the period 1998-2006, using a dense station network over Greece. Satellite products were divided into three groups according to their spatial resolution. The first group had high spatial (0.5°) resolution and consists only of Tropical Rainfall Measuring Mission (TRMM) products: the TRMM Microwave Imager (TMI) precipitation product (3A12) and the TRMM multisatellite precipitation analysis products (3B42 and 3B43). The second group comprised products with medium spatial (1°) resolution. These products included the TRMM 3B42 and 3B43 estimates (remapped to 1° resolution) and the Global Precipitation Climatology Project one-degree daily (GPCP-1DD) analysis. The third group consisted of low spatial (2.5°) resolution products and included the 3B43 product (remapped to 2.5° resolution), the GPCP Satellite and Gauge (GPCP-SG) product, and the National Oceanographic and Atmospheric Administration Climate Prediction Center (NOAA-CPC) Merged Analysis (CMAP). Rain gauge data were first gridded and then compared with monthly and seasonal precipitation totals as well as with long-term averages of the six satellite products at different spatial resolutions (2.5°, 1°, and 0.5°). The results demonstrated the excellent performance of the 3B43 product over Greece in all three spatial scales. 3B42 from the first and second group and CMAP from the third exhibited a reasonable skill.

    The Hellenic plate boundary region, located in the collision zone between the Nubian/Arabian and Eurasian lithospheric plates, is one of the seismo-tectonically most active areas of Europe. During the last 15 years, GPS measurements have been used to determine the crustal motion in the area of Greece with the aim to better understand the geodynamical processes of this region. An extended reoccupation network covering whole Greece has been measured periodically in numerous GPS campaigns since the late eighties, and a continuous GPS network has been operated in the region of the Ionian Sea since 1995. In this paper, we present a new detailed high-quality solution of continuous and campaign-type measurements acquired between 1993 and 2003. During the GPS processing, a special effort was made to obtain consistent results with highest possible accuracies and reliabilities. Data of 54 mainly European IGS and EUREF sites were included in the GPS processing in order to obtain results which are internally consistent with the European kinematic field and order to allow for a regional interpretation. After an overview of the results of the IGS/EUREF sites, the results from more than 80 stations in Greece are presented in terms of velocities, time series, trajectories and strain rates. Previous geodetic, geological and seismological findings are generally confirmed and substantially refined. New important results include the observation of deformation zones to the north and to the south of the North Aegean Trough and in the West Hellenic arc region, arc-parallel extension of about 19 mm/yr along the Hellenic arc, and compression between the Ionian islands and the Greek mainland. Due to continuous long-term observations of 4-8 years, it was possible to extract height changes from the GPS time series. In Greece, we observe a differential subsidence of the order of 2 mm/yr between the northern and central Ionian islands across the Kefalonia fault zone. The differential subsidence

    2014-12-01

    In the beginning of July 2010, a ground fissure was observed in the field near the village of Mavropigi (Northern Greece) and specifically in its NW side. Later on (early September), a second ground fissure was perceived, close and almost parallel to the first one and very close to the limits of the lignite exploitation mine (by the Public Power Corporation, PPC). It was observed that the village of Mavropigi slides away slowly towards the PPC lignite mine. Geological, seismological, as well as geotechnical survey in the field indicated that the phenomenon is related to the coal mining exploitation in the near vicinity of the village rather than to any seismotectonic activity in the surrounding area.

    This article investigates the natural radioactivity of 26 ash samples, laboratory produced from lignite samples collected in the West Macedonia Lignite Center in Northern Greece. The activity concentrations of {sup 40}K, {sup 235}U, {sup 238}U, {sup 226}Ra, {sup 228}Ra, and 232Th were measured by spectroscopy and found four to five times higher than those in the original lignite samples. The radionuclides transfer factors depend on the characteristics of the combustion process and were found higher for {sup 232}Th, {sup 228}Ra, and 40K, because of their closer affinity with the inorganic fraction of the lignite. Compared with other results found in the published literature, the studied ash has relatively high content in radioactivity, but the resulting radiation dose from the radionuclide emissions in the West Macedonia Lignite Center do not contribute significantly to the total effective dose.

    Background Sandfly-transmitted phleboviruses cause to humans an asymptomatic or mild infection to severe meningitis or encephalitis. Phleovirus infections are common in the Mediterranean countries during the summertime when sandflies are active. It is estimated that several cases remain undiagnosed. Description of case In July 2013, a 45-year-old Greek male, was admitted to the General Hospital of Florina in northwestern Greece with two-day history of fever, myalgia, arthralgia, mild headache, and hemorrhagic exanthema. A serum sample obtained from the patient on the 6th day of illness was tested negative for West Nile virus infection. Instead, high titers of IgM and IgG antibodies against Toscana virus (TOSV) were detected, with low titers against sandfly fever Naples virus and no reactivity against sandfly fever Sicilian and Cyprus viruses, suggesting that the causative agent was TOSV or other phlebovirus with antigenic similarity to TOSV. Conclusion Phleboviruses have to be included in the differential diagnosis of acute summer febrile cases, accompanied or not by neurological symptoms. Effort has to be paid to test clinical samples during the first days of the disease when the virus is detectable by molecular or isolation methods, in order to elucidate the complex epidemiology of phleboviruses in the Mediterranean area.

    Sixty-four samples from the groundwater resources of Trikala municipality, central Greece, were collected during two periods (2006 and 2007) and analyzed for physico-chemical parameters (temperature, pH, specific electrical conductivity, and total dissolved solids), major ions (Ca(2+), Cl(-), HCO(3)(-), K(+), Mg(2+), Na(+), NO(3)(-), SO(4)(2-)), and several potentially toxic elements (Al, B, Ba, Br, Ca, Ce, Cl, Cr, Cu, Fe, K, La, Li, Mg, Mn, Mo, Na, Nd, Ni, P, Pb, Rb, S, Sc, Si, Sn, Sr, U, V, Y, Zn). European Council directives and USEPA guidelines were used to assess the water quality. The results indicate that all samples are fresh water, suitable for human consumption. All basic ions and physico-chemical parameters have average concentrations below their recommended optimum limits with the exception of electrical conductivity, for January 2007, and nitrate for October 2006 and January 2007 sampling periods. This exceedance is the result of dissolution of minerals such as calcite and dolomite that are present in the surrounding rocks and the application of fertilizers, respectively. Lead is the only element with an average value that exceeds the recommended EC guideline, while special attention should be paid to one borehole (T9) which has elevated NO(3)(-) values which may pose a risk to human health.

    Easter is the most important holiday for the Greek Church. It is rich in traditions and rituals but during the Greek Easter festivities, especially at midnight Mass on Easter Saturday night, it is customary to throw fireworks around. These fireworks are not part of the true Easter tradition and they are potentially fatal. Unfortunately, in the past few years, the custom has become more and more popular in Greece. There are some local variations, mainly in the Aegean islands, where homemade rockets are used to have a "rocket war". The rockets consist of wooden sticks loaded with an explosive mixture containing gunpowder and launched from special platforms. Many severe injuries involving loss of sight and limbs as well as major burns are also caused by the use of illegal fireworks at Easter. Every year numerous burn victims are hospitalized. The most affected areas are the face, the upper extremities, and the chest, often in association with slight or severe wounds and injuries. This study presents our department's experience with incidents due to the use of fireworks during Easter festivities. PMID:23766749

    Since its last eruption in 1950, Santorini volcano (Greece) remained in a dormant state. This is also evidenced for the period 1992-2010 by the gradual deflation signal over Nea Kameni as measured by satellite Synthetic Aperture Radar Interferometry (InSAR) with low rates of about 5-6 mm yr-1 as well as by the absence of seismic activity within the caldera. However, at the beginning of 2011 the volcano showed signs of unrest with increased microseismic activity and significant ground uplift, reaching 14 cm within a year (2011 March-2012 March), according to InSAR time-series. ALOS PALSAR data indicate the onset of the phenomenon in early 2010 where an aseismic pre-unrest phase of increased subsidence (1-3 cm) preceded the uplift. Joint inversions of SAR and GPS velocities using spherical and spheroidal magmatic source types indicate their location offshore at about 1 km north of Nea Kameni and between 3.5 and 3.8 km depth. The estimated volume variation rate is 6 × 106 m3 yr-1 to 9 × 106 m3 yr-1. A gradual slowing in the rate of inflation within the first quarter of 2012 is apparent by ENVISAT data, while subsequent observations from RADARSAT-2 confirm the observed trend.

    This space radar image of Athens, Greece, shows the sprawling, modern development of this ancient capital city. Densely populated urban areas appear in shades of pink and light green. The Acropolis the dark green triangular patch in the center of the image. Archaeological discoveries indicate Athens has been continuously occupied for at least the last 5,000 years. Numerous ships, shown as bright dots, are seen in the harbor areas in the upper left part of the image. The port city of Piraeus is at the left center. This image is 45 kilometers by 45 kilometers (28 miles by 28 miles) and is centered at 37.9 degrees north latitude, 23.7 degrees east longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations are as follows: red is L-band, horizontally transmitted and received; green is L-band, horizontally transmitted and vertically received; and blue is C-band, horizontally transmitted and received. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) on October 2, 1994 onboard the space shuttle Endeavour. SIR-C/X-SAR, a joint mission of the German, Italian and United States space agencies, is part of NASA's Mission to Planet Earth program.

  17. Trend analysis of air temperature time series in Greece and their relationship with circulation using surface and satellite data: recent trends and an update to 2013

    2016-07-01

    In this paper, the surface and lower tropospheric temperature trends in Greece and their relationship to the atmospheric circulation for the period 1955-2013 were examined, updating the study of Feidas et al. (Theor Appl Climatol 79:185-208, 2004) for data observed during the 12-year period 2002-2013. The trend analysis is based on a combination of three statistical tests. The trends are now examined for all the seasonal time series, new atmospheric circulation indices were added in the analysis, and maps with the spatial distribution of correlation between air temperature and atmospheric circulation were constructed and analysed. The series updated to 2013 for 18 stations reveal a clearer positive trend than that found for the period 1955-2001 on both the annual and the seasonal timescales. The warming signal detected only in summer in the study of Feidas et al. (Theor Appl Climatol 79:185-208, 2004) has now intensified and spread in other seasons. This warming appears to be mainly caused by the very high temperatures in the last decade (after 2004) of the record. At the national scale, there is now a match between surface temperature trends in Greece and Northern Hemisphere (NH) but only for summer, spring and annual time series, which are the only time series presenting a statistically significant warming trend in Greece. Satellite-induced lower tropospheric temperatures now show a statistically significant tropospheric temperature warming trend for the period 1979-2013, for both areas (Greece and NH). Lower tropospheric and surface air temperatures for the same period (1979-2013) show a very good agreement, with differences only in winter and summer for Greece. The influence of atmospheric circulation on the temperature variability in Greece was also examined using two more circulation indices: the Eastern Mediterranean Pattern Index (EMPI) and the North-Sea Caspian Pattern Index (NCPI). EMPI and especially NCPI explain better now the temperature variance in

    The role of volunteers in disaster management is of decisive importance, particularly for major catastrophes. In Northern Europe, volunteers are the main group that responds even in regular low impact incidents. On the other hand, in Southern Europe, state professionals hold the primary role. This is partly cultural, but it is also defined by the different types of hazards involved. For example, Southern Europe suffers from earthquakes and wildfires that can cause severe and widespread damage. This implies that there is a need for highly trained and skilled personnel, not only for efficiency purposes, but also in order to avoid casualties among the operating staff. However, the need of volunteers' involvement is well recognised both for prevention measures (mainly regarding forest fires) and for disaster management purposes particularly during major catastrophes whereas the professional personnel are outsourced. Moreover, the economic crisis stretches the public sector, decreasing the capability and resources of the state mechanism. The latter increases the need for the volunteers' active participation, which is also regarded as cost effective. Greece has a short tradition regarding volunteers and their official involvement with natural hazards. This is also due to the fact that civil protection has a short history in Greece, since it was established in 1995, whereas its legal framework was only shaped in 2002. The act 3013/2002 introduces officially the role of volunteers within the legal framework. In particular, the act N3013/2002 offers a detailed description of the role of voluntary organizations within the civil protection system, the interagency cooperation, and the financial instruments through which the various bodies secure their funding along with the establishment of an inventory from the General Secretariat of Civil Protection.

    Volos city and its port are situated in the northern part of Pagassitikos Gulf, a shallow, semi-enclosed marine area in central Greece. A wastewater treatment plant (WWTP) and pipeline operate in the same area. Muddy sediments with low carbonate contents cover most of the seabed, except for the Volos embayment and the western part of the gulf where sandy carbonates prevail. Bulk organic carbon contents and the organic carbon contents of the clay fractions are high in the vicinity of Volos embayment. High element (Pb, Cu, and Zn) contents and Igeo (geoaccumulation index) values were found for the clay fractions in the northern part of Pagassitikos Gulf. This enrichment is attributed to the discharge of raw domestic and industrial effluents of Volos city and port before the WWTP was installed. The dispersal of pollutants is essentially controlled by diffusion from point sources (city, port and WWTP) and is limited to Volos Bay. Relatively high Mn levels are ascribed to diagenetic formation of manganese carbonates (authigenic phase), whereas Cr and Ni are elevated due to weathering of ultrabasic formations on land.

    Malaria, which was endemic in Greece in the past, was officially eliminated in 1974. Since that time and up to 2010, a number of imported cases (ranging from 19 to 76) have been annually reported. The total number of reported laboratory-confirmed cases between 1975 and 2010 was 1,419. Plasmodium falciparum was identified in 628 (44%) of these cases, while P. vivax was found in 524 (37%). Of the total cases, 1,123 (79%) were male (ratio males vs. females: 3.78). Age was only available for 490 cases, of which 352 (72%) belonged to the 18-40 year-age group. Of the 382 malaria cases reported from 1999 to 2010 for which the region/country of acquisition was known, 210 (55%) were from Africa and 142 (37%) from Asia. The massive introduction of economic migrants, in the period from 1990 to 1991 and from 2006 onwards, mainly from countries where malaria is endemic, resulted in the appearance of introduced sporadic cases. In Peloponnese, Central and East Macedonia, Thrace and East Attica, mosquitoes of the genus Anopheles (e.g. Anopheles sacharovi, A. superpictus and A. maculipenis) that can act as plasmodia vectors are abundant and during the summer of 2011, 27 P. vivax cases were reported in Greek citizens residing in the agricultural area of Evrotas in Lakonia and without travel history. As further P. vivax malaria cases occurred in the Lakonia and East Attica areas in 2012, it is becoming urgent to strengthen surveillance and perform integrated mosquito control that will help eliminate the potential risk of malaria reintroduction and reestablishment.

    The objective here is to use the geology and tectonics of a critical part of the Tethyan orogen, represented by Greece and Albania, to shed light on the tectonic development of Tethys on a regional, to global scale, particularly the history of convergence during Late Palaeozoic to Cenozoic time. For Carboniferous time much evidence suggests that the Korabi-Pelagonian crustal unit as exposed in Albania and Greece formed above a northward-dipping subduction zone along the Eurasia continental margin, with Palaeotethys to the south. However, there is also some evidence of southward subduction beneath Gondwana especially from southern Greece and central southern Turkey. Palaeotethys is inferred to have closed in Europe as far to the east as the longitude of Libya, while remaining open beyond this. There is still uncertainty about the Pangea A-type reconstruction that would restore all of the present units in the area to within the E Mediterranean region, versus the Pangea B-type reconstruction that would require right-lateral displacement of exotic terranes, by up to 3,500 km eastwards. In either reconstruction, fragments of the Variscan collisional orogen are likely to have been displaced eastwards (variable distances) in the Balkan region prior to Late Permian-Early Triassic time. From ~Late Permian, the Greece-Albania crustal units were located in their present relative position within Tethys as a whole. From the mid-Permian, onwards the northern margin of Gondwana was affected by crustal extension. A Mesozoic ocean (Pindos-Mirdita ocean) then rifted during Early-Middle Triassic time, culminating in final continental break-up and seafloor spreading during the Late Triassic (Carnian-Norian). Subduction-influenced volcanics of mainly Early-Middle Triassic age probably reflect the extraction of magma from sub-continental lithosphere that was enriched in subduction-related fluids and volatiles during an earlier, ?Variscan subduction event. The existence of Upper Triassic

    The Special Olympics is a non-profit organization that was officially founded in 1968. Nowadays, the Special Olympics have evolved to a Global Movement that offers the opportunity to more than 3 million athletes with mental or physical disabilities from 185 countries to participate. The Special Olympics will take place in Greece from June 25 until July 4, 2011, where 7500 athletes from 185 countries will participate in 22 Olympic-type games. Mass gatherings such as Olympic Games represent a significant challenge for public health. This paper focuses on relevant health and safety issues for all travellers travelling to Greece for the summer 2011 Special Olympic Games. PMID:21570357

    Background of the Study. Following a large West Nile virus (WNV) epidemic in Northern Greece in 2010, an active mosquito surveillance system was implemented, for a 3-year period (2011, 2012, and 2013). Description of the Study Site and Methodology. Using mainly CO2 mosquito traps, mosquito collections were performed. Samples were pooled by date of collection, location, and species and examined for the presence of WNV. Results. Positive pools were detected in different areas of the country. In 2010, MIR and MLE values of 1.92 (95% CI: 0.00-4.57) and 2.30 (95% CI: 0.38-7.49) were calculated for the Serres Regional Unit in Central Macedonia Region. In 2011, the highest MIR value of 3.71(95% CI: 1.52-5.91) was recorded in the Regions of Central Greece and Thessaly. In 2012, MIR and MLE values for the whole country were 2.03 (95% CI: 1.73-2.33) and 2.15 (95% CI: 1.86-2.48), respectively, for Cx. pipiens. In 2013, in the Regional Unit of Attica, the one outbreak epicenter, MIR and MLE values for Cx. pipiens were 10.75 (95% CI: 7.52-13.99) and 15.76 (95% CI: 11.66-20.65), respectively. Significance of Results/Conclusions. The contribution of a mosquito-based surveillance system targeting WNV transmission is highlighted through the obtained data, as in most regions positive mosquito pools were detected prior to the date of symptom onset of human cases. Dissemination of the results on time to Public Health Authorities resulted in planning and application of public health interventions in local level. PMID:27294111

    Several studies indicate an association between economic crises and psychological burden. To investigate the possible impact of the current economic crisis on mental health in Greece, the association between two economic indicators (unemployment and average income) and mental health variables (psychiatric clinic admittance, visits to outpatients' departments and emergency units, suicides, homicides, mortality rates and divorces) was studied. The data were gathered by the Greek Statistical Service and some others were provided by the following hospitals: Eginition Hospital, Psychiatric Hospital of Attica, Athens General Hospital and Evaggelismos Hospital. Simple and multiple regression analyses were performed on the data. There was no significant correlation between the level of unemployment, as well as the average income, and admittance to the psychiatric clinics. A significant correlation was isolated between unemployment and visits to outpatients' department (R2 = 0.40, p = 0.001) and emergency unit (R2 = 0.49, p = 0.0002) of Eginition Hospital. The unemployment rate during the period 1981-2008 was positively associated with the number of homicides (R2 = 0.16, beta = 0.000049, p = 0.03), as well as the number of divorces (R2 = 0.20, beta = 0.005, p = 0.02) during the same period. The average income showed positive association with the visits to both outpatients' department (R2 = 0.55, p < 0.001) and emergency unit (R2 = 0,37, p = 0.004) of Eginition Hospital. However, the data from the 4 hospitals of the study revealed a negative correlation between average income and visits to outpatients' departments (R2 = 0.70, p = 0.02) and emergency units (R2 = 0.90, p < 0.001). Furthermore, a significant negative correlation between the average income and suicide rates (R2 = 0.37, p = 0.007), as well as a positive correlation between the average income and divorce rates (R2 = 0.73, p < 0.001) were found. The findings show several similarities with previous surveys in

    The European experimental site EUROSEISTEST has been established since 1993 in the epicentral area of the June 20th 1978 earthquake (40.8˚ N, 23.2˚ E, Ms 6.5, Imax VIII+ MSK, Papazachos et al., 1979), located in the active tectonic Mygdonian basin, 30km NNE from Thessaloniki, Greece. Euroseistest has been funded by the European Commission - Directorate General for Research and Development under the framework of consecutive EC research projects (EuroseisTest, EuroseisMod and Eurroseisrisk). It is specially designed and dedicated to conduct experimental and theoretical studies on site effects, soil and site characterization and soil-foundation-structure interaction phenomena. The geological, geophysical and geotechnical conditions of the Euroseistest valley (Mygdonian graben) is very well constrained through numerous in situ campaigns and laboratory tests. The permanent accelerometric network comprises 21 digital 3D stations, including vertical arrays down to 200m (schist bedrock), covering a surface of about 100 sq Km. The site is also covered by a permanent seismological network. A number of high quality recordings, from temporary and permanent arrays, gave the possibility to perform advanced experimental and theoretical studies on site effects (e.g. Raptakis et al., 1998; Pitilakis et al., 1999; Raptakis et al., 2000; Chávez-García et al., 2000; Makra, 2000; Makra et al., 2001 & 2005). The main advantage of Euroseistest is the detailed knowledge of the 3D geological-geotechnical structure of the basin (Manakou, 2007) and its dense permanent accelerometric network. For this reason the site has been recently selected by CEA to validate and check the advanced numerical codes to be used in Cadarache ITER project. Besides the study of site effects, Euroseistest offers interesting possibilities to study SSI problems through two model structures (scaled 1:3).

    Tornado activity is associated with extreme convective weather which can cause extended damage and even in some cases the loss of life. The complex inland terrain of Greece along with the Ionian Sea at the west and the Aegean Sea at the east appear to be a favorable area for fury phenomena such as tornadoes, waterspouts and funnel clouds. In this study, the spatial and temporal variability of tornado activity in Greece for the period 1900-1999 are presented. The spatial distribution of tornadoes, waterspouts and funnel clouds reveals the vulnerability of specific geographical areas, such as the west Greece and the south Aegean Sea. As far as the intra annual variability is concerned, the maximum of tornado activity dominates within the cold period of the year (October-March) while according to the daily distribution, tornadoes happen frequently during the warm hours of the day. It is remarkable to mention that in Greece, within the 20th century, the tornado activity caused the loss of 4 lifes, the injury of 40 people and numerous damages on human constructions and cultivations.

    Tornado activity is associated with extreme convective weather which can cause extended damages and even more in some cases the loss of life. The complex inland terrain of Greece along with the Ionion Sea at the west and the Aegean Sea at the east appear to be a favorable area for fury phenomena such as tornado, waterspouts and funnel clouds. In this study, the spatial and temporal variability of tornadoes activity in Greece for the period 1910-1999 are presented. The spatial distribution of tornadoes, waterspouts and funnel clouds reveals the vulnerability of specific geographical areas to tornado activity, such as the western Greece and the southern Aegean Sea. As far as the intra annual variability is concerned, the maximum of tornadoes activity dominates within the cold period of the year (October-March) while according to the daily distribution, tornadoes happen frequently during the warm hours of the day. Furthermore, especially for the cases after 1957, the prevailing synoptic conditions during the tornado activity, based on the analysis of the 500 hPa Geopotential Heights from the archives of the European Centre for Medium-Range Weather Forecasts (ECMWF), were examined, in order to identify the weather patterns associated with the tornado genesis and development. It is remarkable to mention that in Greece, within the 20th century, the tornado activity caused the loss of 4 lifes, the injury of 40 people and numerous damages on human constructions and cultivations.

    Greek coastline that accounts more than 16.000 km hosts hundreds of beaches, which constitute a great touristic destination. However, no gathered information exists relative to its qualitative and quantitative characteristics (e.g. physicogeographical characteristics, artificial structures, nearby land use). Therefore, the development of a coastal database that would successfully concentrate all relative data, in the form of a National Inventory, could be a valuable tool for the management and the sustainable use and exploitation of beaches and the coastal zone. This work presents an example of the development of a beach inventory in the case of the beach zones of Heraklion and Lassithi counties in the Island of Crete, which is one of the most touristic areas in Greece. Data were initially abstracted from satellite images and combined with in situ observations carried out along 98 beaches with shoreline length >100 m. The collected data included geomorphological, topographic and bathymetric mapping, sediment sampling from the subaerial and underwater part and recording of artificial structures. The initial mapping showed that beaches represent only the 18%, with 74% of the total coastline to be rocky while 8% of the coastline host some kind of artificial intervention. The combination of satellite and in situ mapping led to the development of a coastal geomorphological map. Beach widths were found to be limited with the majority of beaches (59%) to have maximum widths less than 25 m, 35% to range between 25 and 50m and about 6% with maximum widths >50m. Concerning beach length, the threshold of 1000 m is overcome only by the 46% of the beaches. Beaches with very smooth slopes (<2.5) are infrequent (~6%), whilst beaches with low slopes (2.5-5%) are the majority (42%) along with beaches with moderate slopes (5-7.5%) that account approximately the 32%. Beaches with high slopes (7.5-10%) are about 11%, whereas very high slopes and extremely high slopes are much less

    The article deals with the views on health and disease prevalent in Ancient Greece, the cradle of modern European medicine, focusing on the ever-present myths functioning in that realm despite attempts to rationally explain medical phenomena. On the basis of the works of Hippocrates and Galen, the author has distinguished five different epistemological attitudes towards those phenomena: the holistic, macrocosmological, monistic, anti-hypothetical and eclectic. The first was based on the idea of mechanical and logical causes. In medicine it is marked by determinism connected with climatic conditions. Hippocrates believed that health depended on the weather, in particular on the effects of winds, types of water and properties of soil. Myth emerged in this conception in the way matter - earth, water, air and fire - was conceived, particular in the properties ascribed to them: cold, humidity, aridity and warmth. The author charges that this conception was permeated with ethnocentrism and cites examples invoked by Hippocrates on the basis of his observations on the Scythians. The macrocosmological attitude involves subordinating medicine to cosmology. Man's body is a microcosm. The author cites the treatise 'On Diets', in which the greatest importance both in the universe and in processes taking place in the human body as ascribed to two factors - fire and water. Their combination was said to have played a crucial role in the typology of corporal and mental constitutions. Those features, together with the seasons of the year, mode of behaviour and food, constitute the four forces guiding vital processes. The author then presents the embryogenic conception contained in the cosmological treatise. It was based on such things as numerological speculations, hence - despite its rationalistic assumptions, consigns it to the mythic. The third attitude, the monistic approach, presents a treatise ascribed to Hippocrates 'On the Sacred Disease' and dealing with epilepsy. The

    PM 2.5 and its associated ionic component concentrations (Cl -, Br -, F -, NO 3-, NO 2-, SO 42-, HCOO -, CH 3COO -, H 2PO 4-, Na +, K +, NH 4+, Ca 2+, Mg 2+) were determined in the Archaeological Museum of Thessaloniki (AMT), in Northern Greece, where sculptures and other antiquities dated from the Archaic, Classical, Hellenistic and Roman times are displayed. Indoor and outdoor PM 2.5 samplings were concurrently carried out over a 3-month period. Both sites showed similar temporal variations with indoor PM 2.5 concentrations exceeding outdoor levels. Resuspension of soil dust particles introduced by visitors and restoration works carried out during sampling campaign were concluded as being major indoor sources for fine particles and associated calcium. Sulfate was found to be the dominant ion in indoor aerosol originating from external penetration rather than indoor sources. Increased indoor acidity was also observed resulting from the potential presence of partially neutralized ammonium sulfate.

    West Nile Virus (WNV) is the causative agent of a vector-borne, zoonotic disease with a worldwide distribution. Recent expansion and introduction of WNV into new areas, including southern Europe, has been associated with severe disease in humans and equids, and has increased concerns regarding the need to prevent and control future WNV outbreaks. Since 2010, 524 confirmed human cases of the disease have been reported in Greece with greater than 10% mortality. Infected mosquitoes, wild birds, equids, and chickens have been detected and associated with human disease. The aim of our study was to establish a monitoring system with wild birds and reported human cases data using Geographical Information System (GIS). Potential distribution of WNV was modelled by combining wild bird serological surveillance data with environmental factors (e.g. elevation, slope, land use, vegetation density, temperature, precipitation indices, and population density). Local factors including areas of low altitude and proximity to water were important predictors of appearance of both human and wild bird cases (Odds Ratio = 1,001 95%CI = 0,723–1,386). Using GIS analysis, the identified risk factors were applied across Greece identifying the northern part of Greece (Macedonia, Thrace) western Greece and a number of Greek islands as being at highest risk of future outbreaks. The results of the analysis were evaluated and confirmed using the 161 reported human cases of the 2012 outbreak predicting correctly (Odds = 130/31 = 4,194 95%CI = 2,841–6,189) and more areas were identified for potential dispersion in the following years. Our approach verified that WNV risk can be modelled in a fast cost-effective way indicating high risk areas where prevention measures should be implemented in order to reduce the disease incidence.

    This study concerns the investigation of pigments and efflorescence phenomena on the wall paintings of Kastoria, a rural, non-metropolitan Byzantine town. A large number of representative samples were collected from the murals of three churches, dated to post-Byzantine era (14th-17th c. AD). The identified pigments for the red colour were hematite (Fe2O3), cinnabar (HgS) and minium (Pb3O4), while brown and yellow colours were attributed to mixtures of ochres (Fe-oxides and hydroxides) and lime. The utilization of admixtures of iron, lead and mercury compounds was also attested in order to render specific tones on the painted surfaces. Black and dark blue hues were prepared using black carbon and Mn in some cases. Grey colours were assigned to a mixture of black carbon and lime. Green colour is rather attributed to admixtures of Fe-rich minerals and lime and not to the commonly used green earths. Baryte (BaSO4) was also evidenced as a filler or extender. Phosphorous was detected and connected to proteinaceous material and Mo and Sb were traced which are probably affiliated to Fe-oxides. Regarding efflorescing salts, the determined compounds are: calcite, dolomite, gypsum, halite, nitratine, natron and mirabilite, all of which are related to temperature and humidity changes and moisture fluctuations inside the wall paintings.

    The medical records of 91 dogs with heartworm (Dirofilaria immitis) infection were reviewed, and diagnoses were established by using parasitological and immunological methods. Twenty-one animals were asymptomatic (stage I), 57 had mild to moderate clinical signs (stage II), and 13 had the severe form of the disease including right congestive heart failure and the caval syndrome (stage III). Thoracic radiography revealed right ventricular enlargement in 38 of the dogs, pulmonary vascular enlargement in 43, and parenchymal lesions in 27. Only the cardiac and vascular changes were correlated positively with the clinical stages. D. immitis microfilaraemia was detected in 75 of 85 dogs. Occult infection occurred only in eight stage II and two stage III dogs. Thirty-two of the dogs were treated with thiacetarsamide and 39 were treated with melarsomine, and no differences were found in terms of drug efficacy or complication rate; nine stage II dogs suffered pulmonary thromboembolism and one suffered acute liver disease and there were six fatalities. The 50 treated dogs in stages II and III which were followed up for six months all recovered completely. The performance of 38 of 61 working dogs was completely restored, and the performance of another four was partially restored. PMID:10819132

    Immigrants in Greece are an increasing population, very often threatened by poverty and social exclusion. At the same time Greek government has no formal policy concerning their assimilation in Greek society and this situation generates multiple problems in both immigrants and native population. In this work we suggest that new technology can alleviate these effects and we present specific tools and methodologies adopted by ANCE, in order to support online communities and specifically immigrant communities in Greece. This approach has the potential to support immigrant communities' in terms of the organization of personal data, communication, and provision of a working space for dedicated use. The Information System's operational features are also presented, along with other characteristics and state-of-the-art features in order to propose a general direction to the design of online communities' mechanisms.

    An individual monitoring programme is one of the main components of any radiation protection programme since it constitutes the mean for assessing and thus optimising the doses of occupationally exposed workers. The Greek Atomic Energy Commission (GAEC) is the competent authority for radiation protection and nuclear safety in Greece. GAEC's educational and training activities in the field of occupational radiation protection at the national and regional (Eastern Europe) level are presented, along with the relevant activities of the University of Ioannina in the region of North-West Greece, as an example of a local education and training programme. The curricula of two postgraduate courses addressed to qualified experts and medical physics experts and mainly the modules dedicated to individual monitoring are discussed as well. PMID:21115448

    Hospital infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) constitute a worldwide problem associated with high rates of treatment failure and mortality. In Greece, CRKP have emerged in 2002 due to VIM carbapenemase production and later due to KPC, NDM and OXA-48-like carbapenemases that have become endemic. The molecular epidemiology of CRKP strains is dynamic, as antibiotic consumption and worldwide traveling are strongly associated with global spread of CRKP isolates. Lately, porin defects, such as disruption of OmpK35 and production of OmpK36 variant, have also contributed to carbapenem resistance. In the coming years, the high prevalence of CRKP will require intense infection control measures, while novel molecular patterns may appear. To our knowledge, this is the first review analyzing the molecular epidemiology of CRKP strains in Greece. PMID:27206024

    The status of urban sewerage and stormwater drainage systems in ancient Greece is reviewed, based on the results of archaeological studies of the 20th century. Emphasis is given to the construction, operation, and management of sewerage and stormwater drainage systems during the Minoan period (2nd millennium B.C.). The achievements of this period in dealing with the hygienic and the functional requirements of palaces and cities, were so advanced that they can only be compared to modern urban water systems, developed in Europe and North America in the second half of the 19th century A.D. The advanced Minoan technologies were exported to all parts of Greece in later periods of the Greek civilization, i.e. in Mycenaean, Archaic, Classical, and Hellenistic periods. PMID:15607179

    This paper investigates the adoption and use of electronic invoices (e-invoices) in Greek organizations. The study attempts to evaluate current practices applied in implementing e-invoicing. A field research has been conducted, which is based on a structured questionnaire. The target sample consisted of 42 Greek enterprises. The main issues of the investigation include the existing invoice processing practices, the barriers that prevent the extended adoption and use of e-invoicing, the observed benefits from e-invoicing implementation, and the strategic drivers for transition to e-invoicing. Currently, the use of e-invoicing in Greece is low. However, the research results testify that the adoption of e-invoicing in Greece is promising. Even though, a number of enterprises state that benefits of e-invoicing are not clear yet, the majority of enterprises agree that there are crucial financial priorities that e-invoicing is expected to support.

    Eastern Greek islands have been direct passageways of (mainly Syrian) refugees to the European continent over the past year. However, basic medical care has been insufficient. Despite calls for reform, the Greek healthcare system has for many years been costly and dysfunctional, lacking universal equity of access. Thus, mainly volunteers look after the refugee camps in the Greek islands under adverse conditions. Communicable diseases, trauma related injuries and mental health problems are the most common issues facing the refugees. The rapid changes in the epidemiology of multiple conditions that are seen in countries with high immigration rates, like Greece, demand pragmatic solutions. Best available knowledge should be used in delivering health interventions. So far, Greece is failed by international aid, and cross-border policies have not effectively tackled underlying reasons for ill-health in this context, like poverty, conflict and equity of access.

    The diurnal variations of wind-chill at Thessaloniki, Greece, are considered using hourly data from January 1960 to December 1977. This is the first attempt in Greece to describe bioclimatic conditions using wind-chill data. The hourly values of wind-chill were calculated by Siple-Passel's formula which still appears to be most widely used. The values of wind-chill are discussed in terms of Terjung's scale. Thessaloniki does not experience “frost-bite” conditions during the coldest months but does experience “warm” conditions during the summer period. A comparison of hourly and daily mean values show that the means do not indicate the real range of wind-chill during the day.

    A long-term study on child abuse and neglect in Greece is being carried out at the Institute of Child Health, Athens. A multidisciplinary team is investigating the nature of the problem in Greece, is trying a system of therapeutic intervention to families, is evaluating the adequacy of child protection as it is used in child abuse and neglect, and is examining the efficacy of the law. During a one year period, 5 children cared for in institutions were referred to the program. All were boys. All were children with minor or major handicaps. Two of died from the abusive incident. A study of the circumstances of the injury, and of the conditions in Greek institutions, supports the idea that institutional and family child abuse share many common characteristics. Special mention is made of the Greek circumstances pertaining to child protection and the law. PMID:6226340

    Artificial tanning remains very popular worldwide, despite the International Agency for Research on Cancer classification of ultraviolet (UV) radiation from sunbeds as 'carcinogenic to humans'. Greek Atomic Energy Commission has initiated a surveillance action of the artificial tanning devices in Greece in order to record the effective irradiance levels from the sunbeds and to inform and synchronise the domestic artificial tanning business sector with the requirements of the European Standard EN 60335-2-27:2010. In this direction, in situ measurements of UV emissions from sunbeds in solaria businesses all over Greece were performed from October 2013 until July 2014, with a radiometer and a portable single-monochromator spectrophotometer. Analysis of the measurements' results revealed that effective irradiance in ∼60 % of the measured sunbeds exceeded the 0.3 W m(-2) limit value set by EN 60335-2-27:2010 and only 20 % of the devices could be categorised as UV type 3.

    Little is known about the history of spinal deformities in ancient Greece. The present study summarizes what we know today for diagnosis and management of spinal deformities in ancient Greece, mainly from the medical treatises of Hippocrates and Galen. Hippocrates, through accurate observation and logical reasoning was led to accurate conclusions firstly for the structure of the spine and secondly for its diseases. He introduced the terms kyphosis and scoliosis and wrote in depth about diagnosis and treatment of kyphosis and less about scoliosis. The innovation of the board, the application of axial traction and even the principle of trans-abdominal correction for correction of spinal deformities have their origin in Hippocrates. Galen, who lived nearly five centuries later impressively described scoliosis, lordosis and kyphosis, provided aetiologic implications and used the same principles with Hippocrates for their management, while his studies influenced medical practice on spinal deformities for more than 1500 years.

    The aim of the present study was to contribute to the knowledge of the essential-oil composition of the Calamintha officinalis-nepeta complex in Greece and to clarify the main patterns of its variation. The oils obtained from 22 wild-growing populations of C. glandulosa, C. nepeta, and C. menthifolia were studied. They could be classified into two different chemotypes, which correspond to the main biosynthetic routes of the C(3)-oxygenated p-menthane compounds. Chemotype I includes oils rich in trans-piperitone oxide, cis-piperitone oxide, and piperitenone oxide, while Chemotype II comprises oils rich in pulegone and menthone or menthone and isomenthone. Within both chemotypes, quantitative fluctuations of the main components were observed. Comparison with published data showed that the presence of Chemotype II has not been observed before in C. menthifolia, while Chemotype I has been reported in C. nepeta plants from Greece for the first time.

The main body of data is for remittances to Greece from Germany, but for some years data are available for remittances from Belgium and Sweden as well. The objective of this study is to test the significance of certain factors in terms of their effects on remittances to Greece. These factors are the migrant's income, the migrant's family income, the rate of unemployment, the rate of interest, the exchange rate, and the rate of inflation. The study attempts to see if these factors have had any effect on the volume of remittances. It also attempts to see if there are any structural changes during this period that affect migrants' propensity to remit." PMID:12320908

    Santorini Caldera, in the southern Aegean, is part of a well-developed, and very active volcanic system fueled by subduction along the Hellenic arc that is responsible for the largest volcanic eruption in human history (~1650 B.C.). After approximately 50 years of relative seismic quiescence within the caldera and an episode of minor inflation, the volcano has recently reawakened with an exponentially increasing inflation signal, beginning in January 2011. The GPS network, including 3 continuous stations and biennial surveys of 19 campaign stations, showed essentially no deformation between 2006 and 2010. Following a cluster of microseismicity within the caldera two surveys in June and August 2011 were made, while two additional permanent GPS stations were installed. From this data, we found uplift and nearly-radial expansion up to 1 cm/month. This deformation is well-explained by a Mogi-source at the northern part of the caldera, with an approximately 6-10 million m3 volumetric growth at approximately 4 km depth, and tendency for development of a new dome offshore. It is likely that stresses from this magma source are responsible for a cluster of microseismity that began in January 2011 along a radial lineament of young volcanics, called the 'Kameni Line'.

    Tick-borne rickettsioses are endemic in Greece; however, until recently, only Rickettsia typhi and R. conorii were tested routinely in human samples arriving at the National Reference Center. During the last few years, the identification of different rickettsia species in ticks led to the introduction of other spotted fever group rickettsiae in routine analysis. Under the new scheme, R. massiliae is now tested routinely in human samples; herein, we describe a human case of this infection. PMID:26370425

    This study was designed to genetically characterise the larval stage (coenurus) of Taenia multiceps from ruminants in Greece, utilising DNA regions within the cytochrome c oxidase subunit 1 (partial cox1) and NADH dehydrogenase 1 (pnad1) mitochondrial (mt) genes, respectively. A molecular-phylogenetic approach was used to analyse the pcox1 and pnad1 amplicons derived from genomic DNA samples from individual cysts (n=105) from cattle (n=3), goats (n=5) and sheep (n=97). Results revealed five and six distinct electrophoretic profiles for pcox1 and pnad1, respectively, using single-strand conformation polymorphism. Direct sequencing of selected amplicons representing each of these profiles defined five haplotypes each for pcox1 and pnad1, among all 105 isolates. Phylogenetic analysis of individual sequence data for each locus, including a range of well-defined reference sequences, inferred that all isolates of T. multiceps cysts from ruminants in Greece clustered with previously published sequences from different continents. The present study provides a foundation for future large-scale studies on the epidemiology of T. multiceps in ruminants as well as dogs in Greece. PMID:26688203

    Tornadoes have been reported in Greece during the last decades and recent studies have given evidence that west Greece is a vulnerable area for tornadoes, waterspouts and funnel clouds to occur. In this study, the composite means and anomalies of synoptic conditions for tornadic events (tornadoes, waterspouts and funnel clouds) over west Greece are analyzed and discussed. The daily composite means of synoptic conditions were based on National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP/NCAR) reanalysis datasets, for the period 12 August 1953 to 31 December 2012. The daily composite anomalies were calculated with respect to 30 years climatology (1981-2010) of the synoptic conditions. The analysis was carried out in terms of seasonal and monthly variability of composite means and anomalies of synoptic conditions for specific isobaric levels of 500, 700, 850, 925 hPa and the sea level pressure (SLP). In addition, an analysis and discussion about the dynamic Lifted Index from NCEP/NCAR Reanalysis datasets is presented.

    Biodegraded seep oils, devoid of n-alkanes and most isoprenoid hydrocarbons, were successfully correlated with subsurface crude oils in western Greece primarily using carbon isotopes and the more microbially resistant tricyclic terpane and aromatic steroid hydrocarbon distributions. All the studied oils seem to fit into three major genetic groups which are consistent with the geologic, tectonic, and geographic settings and are presumably related to different source-rock facies. Group I oils are typical of the abundant oil shows in the Epirus province, northwest Greece. Minor but consistent biomarker differences necessitated subgrouping of the Epirus oils, implying derivation from slightly different sources. Group II oils are located in the Katakolon area, northwestern Peloponnese. Group III oils, which are clearly distinct from the other groups, are centered in Zakynthos Island. An oil seep at Trifos, west central Greece, and a subsurface oil from Paxi Island, because of uncertain correlations, are classed intermediate between Group I and II oils. An aromatic steroid hydrocarbon measurement, modified after Mackenzie et al. (1981), appears useful in determining the relative maturity of biodegraded and conventional oils and carbonate rock extracts. ?? 1986.

    The aim of this study was to investigate the beliefs and perspectives of the pharmaceutical industry on generic medication in Greece. Questionnaires were mailed to all 58 members of the Hellenic Association of Pharmaceutical Companies from November 2002 to February 2003. The response rate was 52%, namely 30 questionnaires were completed and returned. The questionnaire requested information on companies' involvement in generics, their opinion on generics' characteristics and on public policies affecting the demand and supply of generic medication. A descriptive analysis of the outcomes, that is percentage comparison through binomial tests and Fisher tests, was performed. According to our findings, 43% of the respondents were involved in the production and distribution of generics and the mean period of their involvement was 12 years. The majority of the respondents were in favor of their companies' involvement in generics, despite the relatively small market share of generics in Greece; 9.7% of total pharmaceutical market in 2003. Bearing in mind that in Greece the promotion of generics is not encouraged, pharmaceutical companies believe that the mandatory introduction of bioequivalence studies is an indirect promotional strategy towards generics. Additionally, the majority declared that their main competitive advantages are their safety, efficacy and effectiveness as well as their economic benefit to the society. Finally, the respondents expressed their preference for the introduction of pharmacoeconomic submissions for drugs' reimbursement by social insurance funds. PMID:16386326

    This study examines the characteristics of wet spells in Greece, using daily rainfall gauge data, over a 40-year period (1958 1997). The longest wet spells, computed for two different thresholds (0.1 mm and 1 mm), were observed in Western Greece and Crete, whereas the shortest ones were found in the central and south Aegean. A detailed analysis of the wet spells, dividing them into three classes, shows that on an annual basis their highest frequencies were observed in Western and Northwestern Greece. The seasonal results are also quite similar. The trends and the variability of the mean length of the wet spells were also analyzed. Negative trends were found in the case of the year-to-year analysis and during winter. Finally, this study presents an evaluation of two theoretical distribution models; the second order Markov Chains (MC2) and the Negative Binomial Distribution (NBD), by their adjustment to the empirical data. Both models can be used in the future for an estimation of the wet spells in the area under study.

    The magmatic history of the Pelagonian Zone, in northern Greece, is constrained with secondary ion mass spectrometer (SIMS) U-Pb dating on zircons of various granitoids whose structural positions were defined with respect to the regional main foliation. Ages pertain to four groups: (i) Mesoproterozoic (circa 1430 Ma) crystallization of granites inferred from inherited magmatic zircon cores that have been partially molten during the (ii) Neoproterozoic at circa 685 Ma (metamorphic zircon rims) and subsequently intruded by a Neoproterozoic leucogranite (circa 600 Ma). (iii) Late- or post-Variscan calc-alkaline granitoids (315-301 Ma) were in turn intruded by a subvolcanic dike at about 280 Ma. In the Early Permian the ɛNd(t) in magmas decreased from -7.3 to -1.3, hinting to mantle-derived melts produced during extension. Rifting is further heralded by two acidic and one mafic dike containing Lower-Middle Triassic zircons (246-242 Ma). (iv) Early Cretaceous anatectic melts at 117 ± 8 Ma formed during regional metamorphism. This age is the first report of in situ anatexis in the Pelagonian Zone. Cretaceous anatexis developed during the Mesozoic collision of Pelagonia with the Eurasian margin. Major- and trace-element geochemistry of amphibolites further attests for the complex pre-Alpine tectonic history with Neoproterozoic calc-alkaline and back-arc geochemical signature and Triassic alkali-magmatism.

    The aim of this study was to investigate the occurrence of endocrine disrupting compounds (EDCs) in a complex urban atmosphere. Target compounds were alkylphenols (NP, tOP, nOP), nonylphenol monoethoxylate (NP1EO), bisphenol A (BPA), tetrabromobisphenol A (TBBPA), and phthalates (DMP, DEP, DBP, BBP, DEHP, DNOP). EDCs were determined in ambient PM10 from two sampling sites, one urban-traffic and one urban-industrial, located in the city of Thessaloniki, northern Greece. At both sites, DEHP and NP were found to be the predominant EDCs in airborne PM10. Concentrations of NP did not exhibit any spatial difference, whereas concentrations of DEHP were significantly higher at the urban-traffic site. Wind direction was not found to have any significant effect on ambient EDCs concentrations suggesting impact from local sources rather than transport; however some peak concentrations might be attributed to short-distance sources. The gas/particle partition coefficient, Kp, and the gaseous phase of EDCs were calculated by employing two approaches based on literature data (a) for the subcooled liquid vapor pressure ( PL0) and (b) the octanol-air partition coefficient ( KOA). It appeared that the g/ p partition of phthalates estimated by the KOA approach is in better agreement with experimental partition data reported by other investigators. Absorption in organic matter was found to be significant partition mechanism at the urban-traffic site.

    Several minor lignite deposits of Palaeogene (Eocene to Oligocene) age occur in the vicinity of Alexandroupolis, Thrace, northern Greece. A few, rather thin seams were mined in the past by small private operations for local use. Coal samples have been collected from old mine dumps and outcrops around abandoned mine posts to be studied by means of maceral analysis at high magnification. The groundwater and vegetation index are calculated from the maceral composition and used to draw conclusions concerning the environment of deposition. In addition, block samples of coal cut perpendicular to bedding were studied at intermediate magnification and underfluorescence, thus revealing some interesting bedding features as well as well-preserved plant organisms. The coals are characteristically finely laminated and highly gelified. Palynological preparations have thus far yielded only poorly preserved palynomorph assemblages, rather low in diversity and dominated by fern spores. This fern dominance is rather unusual: however, it is compatible with the occurrence of fertile fern fronds observed in petrographic coal sections. Accompanying clastic sediments exhibit cyclic fining-upward sequences at a scale averaging about 1 m in vertical extent. Grain sizes range from small gravel to clay and silt. In some cases, siltstones in the roof of coal seams include abundant plant fragments showing parallel venation. The evidence presented from various sources suggests a rather unstable fluvial environment and a generally high water table on the flood plain for the formation of these lignites.

    Background SNP data of goats of three Mediterranean countries were used for population studies and reconstruction of geographical patterning. 496 individuals belonging to Italian, Albanian and Greek breeds were genotyped to assess the basic population parameters. Results A total of 26 SNPs were used, for a total of 12,896 genotypes assayed. Statistical analysis revealed that breeds are not so similar in terms of genetic variability, as reported in studies performed using different markers. The Mantel test showed a strongly significant correlation between genetic and geographic distance. Also, PCA analysis revealed that breeds are grouped according to geographical origin, with the exception of the Greek Skopelos breed. Conclusion Our data point out that the use of SNP markers to analyze a wider breed sample could help in understanding the recent evolutionary history of domestic goats. We found correlation between genetic diversity and geographic distance. Also PCA analysis shows that the breeds are well differentiated, with good correspondence to geographical locations, thus confirming the correlation between geographical and genetic distances. This suggests that migration history of the species played a pivotal role in the present-day structure of the breeds and a scenario in which coastal routes were easier for migrating in comparison with inland routes. A westward coastal route to Italy through Greece could have led to gene flow along the Northern Mediterranean. PMID:19725964
