    The island of Cyprus has a long historical record of earthquakes that have damaged pre-Roman to modern human settlements. Because the recurrent damaging earthquakes can have a significant economic and social impact on Cyprus, this project was initiated to develop a seismic-hazard assessment for a roughly 400 square kilometer area centered on Cyprus' capital and largest city, whose European name is Nicosia and whose local name is Lefkosia. In addition, geologic and seismotectonic evaluations for the project extended beyond the perimeter of the geologic map. Additional structural, stratigraphic, and paleontological data were collected island-wide as well as data from literature research throughout the eastern Mediterranean region, in order to accurately place the geology and seismic hazards of the Lefkosia area in a regional tectonic framework.

    Cyprus has an area of 9251 square km or 3572 square miles with a population of 735,000 of whom 565,000 were Greeks and 170,000 Turks in 1991. Literacy is 99%, infant mortality is 10/1000, and life expectancy is 73 years for males and 78 for females. The history of the island goes back to BC 3700. It has been divided since the Turkish military invasion of 1974 that followed a coup attempt by the Greek military junta which wanted to oust President Makarios for abandonment of the union with Greece. There have been UN sponsored negotiations between the 2 communities to establish a new constitution of a federal, bicommunal, and bizonal basis. The economy has recovered since the mid-1970s when 230,000 refugees were jobless. Cyprus has a custom's union agreement with the European Community, and applied for full membership in 1990. In the Greek zone light manufacturing and services grew rapidly in 1990. More than 1.5 million tourists visited Cyprus in 1990. However, agricultural production and exports (potatoes and citrus) decreased in 1990. Tourism also declined, while the budget deficit increased, but there are more favorable economic forecasts for 1992. Turkey provides a large amount of development assistance, and takes a large share of imports from the Turkish sector that fared much worse economically than the Greek zone. PMID:12178034

    The aim of this study which was performed within working group 4 in the FloodFreq COST Action is to assess and quantify changes in daily streamflow and subsequent flood response modelling due to potential climate change in Yermasoyia watershed, Cyprus. Eight statistical downscaling methods are used to estimate historical and future daily precipitation and temperature timeseries. Four methods are based on change factors and four are bias correction methods and these methods are used to downscale precipitation and temperature output from fifteen RCMs from the ENSEMBLES project. Several well-known lumped hydrological model structures (such as the GR4J, the IHACRES models, and the AWBM) are applied to estimate the daily streamflows. Performance of the models is evaluated with the use of fit statistics or metrics for calibration and validation periods using the split sample test. A set of flood indices are derived from the daily simulated streamflows and their changes have been evaluated by comparing the periods 1960-1990 and 2070-2100. The results show that both the magnitude and the volume of annual peakflows is decreasing fow all examined scenarios, downscaling methods and employed hydrological models.

    forest cover. To examine the efficacy of LiDAR in mineral exploration, an airborne survey was flown over approximately 375 km2 of the Troodos ophiolite, Cyprus—a region noted for its volcanogenic massive sulphide (VMS)-style mineralisation. Although most commonly found at the Lower Pillow Lava-Upper Pillow Lava interface, sulphide mineralisation occurs throughout the pillow lava sequence. Therefore, accurate identification of geological contacts is a key parameter for VMS exploration in the Troodos complex. However, the existing geological maps, produced using a combination of conventional field mapping and aerial photograph interpretation, have significant differences and do not adequately represent the geological complexity in high detail. In this study, we present a semi-automated algorithm for the detailed lithological mapping of a 16 km2 study area using high-resolution (4 m) airborne LiDAR topographic data in which non-ground features such as trees and buildings have been removed (i.e., bare-earth). Differences in the geomorphological characteristics of each major lithological unit result in each unit having a distinctive topographic signature in the bare-earth LiDAR DEM. Thematic maps (slope, curvature and surface roughness) are derived from the LiDAR DEM in order to quantify the topographic signatures associated with each lithological unit. With the thematic maps as the input layers, Kohonen's Self-Organising Map is used as a supervised artificial neural network to assign each pixel to a lithology to produce a geological map. The algorithm successfully identifies the major lithological units—Basal Group (> 50 % dykes and < 50 % pillow lavas), pillow lavas, alluvium and Lefkara Formation (chalks and marls)—in excellent detail and highlights geological features to a 20 m resolution. Although the ability to distinguish between lithologies in some areas is affected by anthropogenic activity (e.g., farming), the resultant lithological map easily surpasses the

    We investigate first the climatology expressed by diurnal and seasonal variations of the critical frequency (foF2) and the peak height (hmF2) of the F2-layer derived from digital ionosonde measurements at the low-middle latitude European station in Nicosia, Cyprus (geographical coordinates: 35°N, 33°E, geomagnetic lat. 29.38°N, I = 51.7°). Monthly median hourly values of the F2-layer peak characteristics are obtained using manually scaled data during the 5-year period 2009-2013. The observational results are then compared with the International Reference Ionospheric Model (IRI-2012) predictions using both URSI and CCIR coefficients. It is shown that the semi-annual pattern of daytime foF2 characterized by higher values at equinoxes than either solstices as well as the winter anomaly phenomenon demonstrate strong solar activity dependence. An annual pattern of night-time foF2 is also detected with lower values in winter and higher in summer. The seasonal variation of daytime hmF2 is evident and peaks of hmF2 at pre-sunrise and post-sunset hours are identified during December. The IRI-2012 model is capable to capture the main diurnal and seasonal patterns of foF2 and hmF2. The highest overestimation of daytime foF2 is noted at equinoxes and solstices except from March, October, December of 2011, and June of 2013. Significant foF2 underestimation is observed at evening and after midnight during February and March of 2009. Large positive discrepancies between the modeled and observed hmF2 values are noticed during the deep solar minimum year 2009. Overall, IRI-model estimates are more accurate for hmF2 than foF2 over Cyprus and for the examined period.

    The modern mining enterprises have attained such scales of engineering activity that their direct influence to a rock massif and in series of cases to the region seismic regime doesn`t provoke any doubts. Excavation and removal of large volumes of rock mass, industrial explosions and other technological factors during long time can lead to the accumulation of man-made changes in rock massifs capable to cause catastrophic consequences. The stress state changes in considerable domains of massif create dangerous concentration of stresses at large geological heterogeneities - faults localized in the mining works zone. External influence can lead in that case to such phenomena as tectonic rockbursts and man-made earthquakes. The rockbursts problem in world mining practice exists for more than two hundred years. So that its actuality not only doesn`t decrease but steadily mounts up as due to the mining works depth increase, enlargement of the useful minerals excavations volumes as due to the possibility of safe use of the rock massif potential energy for facilitating the mastering of the bowels of the Earth and for making that more cheap. The purpose of present work is to study the engineering activity influence to processes occurring in the upper part of Earth crust and in particular in a rock massif. The rock massif is treated in those studies as a geophysical medium - such approach takes into account the presence of block structure of medium and the continuous exchange of energy between parts of that structure. The idea ``geophysical medium`` is applied in geophysics sufficiently wide and stresses the difference of actual Earth crust and rock massifs from the continuous media models discussed in mechanics.

    Bell Regio is a broad topographic rise located at approximately 30 deg N, 45 deg E which extends approximately 1500 km in the N-S direction and is characterized by extensive volcanism. The geology and surface characteristics of Bell Regio are examined in order to understand the geologic evolution of the region and the surface characteristics of the major volcanic units. Relationships between Magellan SAR backscatter values and altimeter-derived ring slope data are analyzed, and terrestrial SAR data are used to suggest possible surface morphologies.

Dietary habits were assessed cross-sectionally, using a self-completed questionnaire in 193 students enrolled in public and private universities in Cyprus. Adherence to the Mediterranean diet was evaluated using the validated KIDMED index. BMI was estimated based on weight and height measurements. Results. The mean BMI was 23.31 (±3.98). The mean adherence score to the Mediterranean diet was 6.0 (IQR 4 to 8), with 26.9% of students being classified as high adherers and 21.8% as low adherers to the Mediterranean diet. About 32% of students consumed a second serving of fruit and vegetables more than once a day, whereas 26% reported going more than once a week to a fast-food restaurant and 31% consumed sweets and candy several times a day. On the other hand, 76% of participants reported consumption of at least two dairy products daily and 88% use olive oil at home. The majority consume coffee 2-3 times per day. Conclusions. Results support a shift from traditional healthy diets to more unhealthy eating patterns. However, we also report a high dairy intake and use of olive oil. Tailored-made strategies targeting the young adult population could be warranted. PMID:27293883

    The paper presents an annotated catalogue of the millipedes (Diplopoda) of Cyprus, based on literature scrutiny and on hitherto unpublished material. A total of 21 species belonging to 14 genera, 9 families and 7 orders are recorded from the island. Three species are regarded as new to science, but are not formally described, and the status of another three is yet to be clarified. Pachyiulus cyprius Brölemann, 1896 and Strongylosoma (Tetrarthrosoma) cyprium Verhoeff, 1902 are established as junior subjective synonyms of Amblyiulus barroisi (Porat, 1893) and T. syriacum (Humbert & DeSaussure, 1869), respectively, both syn. nov. The present-day diversity of the Cypriotic millipede fauna is analysed in the light of past geological events. It is presumed that the fauna originated from the late Miocene, when Cyprus was formed as a result of uplift of the sea floor. During the Messinian salinity crisis, some 6-5.3 mya, land bridges existed between the island and the neighbouring Taurus Mts. (Turkey) and the region of Latakia (Syria), which are supposed to have served as migratory pathways for various millipede taxa. PMID:25081468

    One of the major objectives of the National Waste Terminal Storage Program is to identify potential geologic sites for storage and isolation of radioactive waste (and possibly irradiated fuel). Potential sites for the storage and isolation of radioactive waste or spent fuel in a geologic rock unit are being carefully evaluated to ensure that radionuclides from the stored waste or fuel will never appear in the biosphere in amounts that would constitute a hazard to the health and safety of the public. The objective of this report is to quantify and present in graphical form the effects of significant geohydrologic and other performance characteristics that would influence the movement of radionuclides from a storage site in a rock unit to the biosphere. The effort in this study was focused on transport by groundwater because that is the most likely method of radionuclide escape. Graphs of the major performance characteristics that influence the transport of radionuclides from a repository to the biosphere by groundwater are presented. The major characteristics addressed are radioactive decay, leach rate, hydraulic conductivity, porosity, groundwater gradient, hydrodynamic dispersion, ion exchange, and distance to the biosphere. These major performance characteristics are combind with each other and with the results of certain other combinations and presented in graphical form to provide the interrelationships of values measured during field studies. The graphical form of presentation should be useful in the screening process of site selection. An appendix illustrates the use of these graphs to assess the suitability of a site.

  13. Seismic and geologic characteristics of drowning events on carbonate platforms

    Carbonate platform drowning events are recorded in Upper Jurassic-Lower Cretaceous carbonates of the Baltimore Canyon area, offshore US East Coast, and lower Miocene carbonates of the Pearl River Mouth Basin, offshore People's Republic of China. Cursory examination of seismic data from both areas would indicate that the platforms fit the classic definition of a drowning unconformity. However, detailed lithologic and paleontologic data indicate that the depositional/erosional hiatuses vary widely in each area, from 0-25 m.y. in the Baltimore Canyon area, to a condensed section with no hiatus in the Pearl River Mouth Basin. The sedimentary sequence produced during drowning in both areas is gradational with underlying shallow platform carbonates and, in some places, overlying deeper marine limestones and shales. The generalized facies models proposed for drowning events suggest that they may appear as instantaneous or gradual changes in geologic and seismic data. Because of this resolution problem, a distinction should be made between seismically and geologically defined unconformity surfaces. The geologic characteristics of drowning events on carbonate platforms include a gradational lower (and sometimes upper) contact, chemical sedimentation (glauconite, phosphate), open-marine shelf sediments, and a variable hiatus at the upper boundary. Data from isolated open-ocean atolls (Pearl River Mouth Basin) indicate that they respond differently to drowning, showing an asymmetric decrease in shallow platform environments as drowning occurs. Proper recognition by a geoscientist of the seismic and geological characteristics of drowning events can lead to better reservoir and seal estimates, and the correct reconstruction of the depositional, tectonic, and eustatic histories of an area.

    Carbonate platform drowning events were recorded in Late Jurassic-Early Cretaceous carbonates of the Baltimore Canyon area, and early Miocene carbonates of the Pearl River Mouth basin. Cursory examination of seismic data from both areas would suggest that the platforms appear to fit the classic definition of a drowning unconformity. Lithologic and paleontologic data however, indicate that depositional hiatuses vary widely in each area (from 0-25 Ma in the Baltimore Canyon area, to no hiatus, but a condensed section in the Pearl River Mouth basin). The sedimentary sequence produced during a drowning event (the drowning sequence) in both areas is gradational with underlying shallow platform carbonates and, in some places, overlying deeper marine limestones and shales. Facies models illustrate that drowning event, in general, can appear as instantaneous or gradual changes in lithologic and seismic data. However, evidence from platforms adjacent to continental margins (Baltimore Canyon) and isolated open ocean atolls and banks (Pearl River Mouth basin) indicates that their response to drowning is different. In addition, bypass/erosional and accretionary carbonate platforms also respond somewhat differently to drowning events. The geologic characteristics of drowning events on carbonate platforms include gradational lower (and sometimes upper) contacts, chemical sedimentation, open-marine shelf sediments, and variable loss of time at the upper boundary. Late-growth shelf margin reefs can also be a diagnostic feature of drowned platforms. Seismic characteristics include horizontal to subhorizontal basinal marine onlap and basin-parallel reflector continuity above the carbonate sequence boundary. Proper recognition of the seismic and geologic characteristics of drowning events can lead to better reservoir-seal predictions, and to correct reconstruction of the depositional and tectonic/eustatic history of an area.

  19. The Initial Appearance of Ashlar Stone in Cyprus. éssues of Provenance and Use

    Philokyprou, M.

    In Cyprus stone was the primary building material, either as rubble or in a dressed form (called ashlar), since the Neolithic period. Initially stone was used only as rubble but later during the Late Brone Age ashlar stone appeared for the first time on the island. The aim of this paper is the presentation of the results of a systematic research regarding the different types and uses of ashlar stone and the techniques followed during the Late Bronze Age in Cyprus in comparison with other Mediterranean areas. The macroscopic and microscopic examination of selected samples showed that sedimentary rocks of various geological formations were used as ashlars. One, two or even three different types of stones were transported from the quarries nearest to the settlements. Some characteristic methods of stone dressing, such as finishing only the visible faces and creating drafted margins around the face of the ashlar blocks, are to be found not only in Late Bronze Age settlements but also in more recent examples from the last two centuries. The choice of ashlar and the methods of construction can be related to social, religious and political factors and were not only based on aesthetic criteria and practical issues. Thus, the most impressive structural solutions were followed in the construction of temples and public buildings, whereas more simple methods can be observed in residential complexes.

A survey carried out to provide an unbiased estimate of current transmission rates in dogs and humans showed a 9-fold increase in dog seroprevalence (reaching 14.9%) compared with 10 years ago. However, no human cases caused by Leishmania infantum were detected, although L. donovani cases were reported recently. The 62 strains isolated from dogs were typed as L. infantum MON-1 (98.4%), which is the predominating zymodeme in the Mediterranean region, and MON-98 (1.6%). The Phlebotomus species P. tobbi (vector of L. infantum in Cyprus), P. galilaeus, and P. papatasi were the predominant species captured.

    The soil geochemical atlas of Cyprus is a recent addition to the series of national to continental-scale geochemical mapping programmes implemented over the last two decades for environmental and resource applications. The study has been conducted at the high sampling density of 1 site per 1km(2), with multi-element and multi-method analysis performed on samples of top soil (0-25cm) and sub soil (50-75cm) from a grid of over 5350 sites across a major portion of Cyprus. Major and most trace elements display sharp concentration changes across the main geological boundaries but a high degree of spatial continuity and consistency of values within those boundaries. Some elements display one to two orders of magnitude difference in median concentrations between the soils developed over ultramafic or mafic units and those developed over sedimentary rocks or alluvial units. The ratio of aqua regia-extractable to total metal contents provides an indication of the general mineralogical host for a number of trace elements. The majority of soils are near-neutral to alkaline with the small proportion of areas with soil pH<5 largely restricted to the major Cu deposits. There is strong correlation between top soil and sub soil geochemical values. Where the concentrations of some elements (including Pb, Hg and Sn) are indicative of contamination, the values are typically higher in the top soil samples in these areas. Variations in the concentration of elements with strong redox controls on mobility are linked to changes in sedimentary environment between deep and shallow marine conditions. Some element patterns can be related to the effects of urbanisation and sulphide mining operations; however the dominant control on soil geochemistry is the parent geology and regolith forming processes. The atlas demonstrates the effectiveness of high-density sampling in mapping local to regional-scale features of the geochemical landscape. PMID:22330424

    With the rapid development of coal industry in China, the emphasis of the geological exploration has been changed from the exposed area to the buried area. Because of the limitation of the geological condition and the exploration methods, it is very difficult to study the geological phenomena in buried coalfield. To the coal geologists in China, to search an effective and practical method has been the important tackle key problem for recent years. In this paper, the authors discussed the characteristics of remote sensing technology in the geological study, and the forming mechanism of remote sensing information in the buried area from the view of agrology and physics, so the important academic evidences were offered for the geological study using remote sensing image in the buried coalfield. The characteristics of the non-remote sensing information, the geophysics information and the basal geological information, were also introduced in the study of buried geological bodies. The authors expounded the general processing method in the investigation of buried geological bodies using remote sensing and non-remote sensing information. At last, the probable distribution area of buried igneous rocks, in Huaibei coalfield in China, were successfully forecasted synthetically using the remote sensing, and non-remote sensing information.

    The engineering properties of the lunar regolith reflect aspects of the original parent rock and the consequences of hypervelocity meteor bombardment. Compared to the Earth the geologic nature of the lunar regolith is quite distinct. On scales relevant to machinery, heterogeneity with respect to size and composition is much higher. But the total range in composition is much more restricted. Both facts have implications for predictions of properties, such as abrasion, which will be required by design engineers for constructing equipment for lunar use. Abrasion is related to hardness and hardness is a commonly measured property for both minerals and engineering materials. Although different hardness scales are routinely employed for minerals and engineering materials, a significant amount of literature is available relating the two. In this paper we discuss how to relate hardness to abrasion for the design of lunar equipment. We also indicate how abundant the various mineral phases are and typical size distributions for lunar regolith.

    Due to a particular geological setting, Cyprus is rich in ore deposits, many of them subject to extensive mining. Most of the mines have a long history, sometimes dating back to prehistorical times. These abandoned mines cause severe off-site environmental problems and health risks for the local population. Groundwater supplies are affected by the leaching of pollutants, surface water is contaminated because of water erosion, and harmful dust containing heavy metals or asbestos is spread due to wind erosion. In addition to the environmental risks associated with the abandoned mines, many of these sites are aestethically unattractive, and remain an economic burden to stakeholders and the public in general, due to the downgrading of surrounding areas, non-development and hence loss of revenue. These factors are important in Cyprus where tourism is a significant source of income for local communities. An EUREKA-project addresses the issue of abandoned mine clean-up and restoration. The main objectives of this study are : (1) To develop phytostabilization and -remediation techniques to stabilize and clean up sites characterized by high nickel and copper concentrations in the soil, using endemic plants (Alyssum spp. and mycorrhizal Pinus brutia). In some old mines, efforts were already made to stabilize slopes in an attempt to minimize soil erosion and spreading of pollutants. These restoration efforts, however, remained largely unsuccessful because vegetation that was planted could not cope with the harsh hydrogeochemical soil characteristics. Regeneration of the vegetation cover therefore failed ; (2) to demonstrate the risks associated to the environmental hazard of metal polluted mine spoils and outline a method by which to accomplish this type of risk assessment ; (3) to analyse costs and benefits of phytostabilization- and phytoremediation-based solution for the problem. Results of the first experiments are still preliminary and incomplete. However, it is expected

    The continental slope of the Gulf basin covers more than 500,000 km/sup 2/ and consists of smooth and gently sloping surfaces, prominent escarpments, knolls, intraslope basins, and submarine canyons and channels. It is an area of extremely diverse topographic and sedimentologic conditions. The slope extends from the shelf break, roughly at the 200-m isobath, to the upper limit of the continental rise at a depth of 2800 m. The most complex province in the basin, and the one of most interest to the petroleum industry, is the Texas-Louisiana slope, occupying 120,000 km/sup 2/ and in which bottom slopes range from less than 1/sup 0/ to greater than 20/sup 0/ around the knolls and basins. The near-surface geology and topography of the slope is a function of the interplay between episodes of rapid shelf-edge and slope progradation and contemporaneous modification of the depositional sequence by diapirism. Development of discrete depocenters throughout the Neogene results in rapid shelf-edge progradation, often exceeding 15-20 km/m.y. This rapid progradation of the shelf edge leads to development of thick wedges of sediment accumulation on the continental slope. Slope oversteepening, high pore pressures in rapidly deposited soft sediments, and changes in eustatic sea level cause subaqueous slope instabilities such as landslides and debris flows. Large-scale features such as shelf-edge separation scars and landslide-related canyons often result from such processes.

    The objective of educating people on family planning and sexuality issues has been carried forth by the Family Planning Association of Cyprus (FPAC) since 1971. The promotion of sex education in schools has generated respect for their expertise. Sex education has reached the agenda of the General Assembly of Parliament only to be postponed due to the April 1991 end of term dismissal. A newly elected Parliament are not expected to act immediately. The Ministry of Education Committee on Health Education has been actively counseled since 1974, and most recently in their examination of the possibilities of school sex education and training of high school teachers. The Ministry of Education has authority over primary and secondary education, which is compulsory up to 3 years of secondary education. The approach of FPAC has been to work with parents first in education lectures at various well publicized locations. The agenda was to inform about FPAC, explain the purpose and meaning of sex education, and show the Merry-Go-Round educational film followed by a question and answer session. Eventually, presentations involved children with parent observation. In 1977, authorization from the Ministry of Education gave official approval to FPAC, but not on school premises. FPAC went directly to headmasters and gained support in primary schools to organize sessions on school premises, which successfully involved many primary schools even in the much needed rural areas. Home Economics and Child Care, offered in the 5th and 6th grades was the only vehicle for gaining permission to enter secondary schools. In Larnaca, secondary school headmasters at the 3rd and 6th grade levels permitted invitations which requested parental permission. Lecture topics on human reproduction, sex roles, and disease and contraception were also provided in a follow-up letter. Higher education levels were involved through youth clubs and evening lectures. In 1988, FPAC urged the Director General of the

    The Mesaverde Group of the Piceance Basin in western Colorado has been a pilot study area for government-sponsored tight gas sand research for over 20 years. This study provides a critical comparison of the geologic, production and reservoir characteristics of existing Mesaverde gas producing areas within the basin to those same characteristics at the MWX site near Rifle, Colorado. As will be discussed, the basin has been partitioned into three areas having similar geologic and production characteristics. Stimulation techniques have been reviewed for each partitioned area to determine the most effective stimulation technique currently used in the Mesaverde. This study emphasizes predominantly the southern Piceance Basin because of the much greater production and geologic data there. There may be Mesaverde gas production in northern areas but because of the lack of production and relatively few penetrations, the northern Piceance Basin was not included in the detailed parts of this study. 54 refs., 31 figs., 7 tabs.

    Marine Spatial Planning (MSP), which is in concept similar to land-use planning, is a public process by which the relevant Member State's authorities analyse and organise human activities in marine areas to achieve ecological, economic and social objectives. MSP aims to promote sustainable growth of maritime economies, sustainable development of marine areas and sustainable use of marine resources. This paper highlights the importance of MSP and provides basic outcomes of the main European marine development. The already successful MSP plans can provide useful feedback and guidelines for other countries that are in the process of implementation of an integrated MSP, such as Cyprus. This paper presents part of the MSP project, of which 80% funded by the European Regional Development Fund (ERDF) and 20% from national contribution. An overview of the project is presented, including data acquisition, methodology and preliminary results for the implementation of MSP in Cyprus.

    In the Harmancık-Bursa region of the western Anatolia (Turkey), an extensive contact metamorphic aureole at the border between the Late Mesozoic coherent metaclastic rocks of blueschist facies and the Early Senozoic intrusive granodiorite stock hosts an interesting and unique gem material with a mineral assemblage consisting mainly of jadeite, quartz, orthoclase, epidote, chloritoid, and phlogopite as identified by X-ray diffraction spectroscopy and polarized-light microscopy. In addition, chemical analyses performed with X-ray fluorescence and inductive-coupled plasma-atomic emission spectroscopy show that the mass of the metamorphic aureole has a silica-rich, calc-alkaline chemical content. Therefore, some rock building elements (such as Al, Ca, Na, K, P, Sr, and B of which characterize an acidic-neutral rock formation) and trace elements (such as Fe, Cr, Mn, Be, Cu, Ga, La, Ni, Pb, and Zn) are remarkable high ratios. Pale purple-colored gem material of this composition appears to be unique to Turkey, also is only found in one narrow provenance in Turkey. Therefore, it is specially called "Turkish (and/or Anatolian) purple jade" on the worldwide gem market. Even though the mineral jadeite is the principal constituent, 40% by volume as determined with petrographic thin-section examination under a polarized-light microscope, the material cannot be considered pure jadeite. Specific gravity measurements of the jade using a hydrostatic balance confirm that it has a heterogeneous structure. The measured average specific gravity of 3.04, is significantly lower than the normal range for characterized jadeites of 3.24-3.43. Turkish purple jade samples were examined in detail using dispersive confocal micro-Raman spectroscopy (DCμRS) as well as other well-known analytical methods. The resulting strong micro-Raman bands that peaked at 1038, 984, 697, 571, 521, 464, 430, 372, 326, 307, 264, and 201 cm -1 are characteristics of the Turkish purple jade. The first most

  13. Modeling geologic storage of carbon dioxide: Comparison ofnon-hysteretic and hysteretic characteristic curves

    2006-07-17

    Numerical models of geologic storage of carbon dioxide (CO2)in brine-bearing formations use characteristic curves to represent theinteractions of non-wetting-phase CO2 and wetting-phase brine. When aproblem includes both injection of CO2 (a drainage process) and itssubsequent post-injection evolution (a combination of drainage andwetting), hysteretic characteristic curves are required to correctlycapture the behavior of the CO2 plume. In the hysteretic formulation,capillary pressure and relative permeability depend not only on thecurrent grid-block saturation, but also on the history of the saturationin the grid block. For a problem that involves only drainage or onlywetting, a non-hysteretic formulation, in which capillary pressure andrelative permeability depend only on the current value of the grid-blocksaturation, is adequate. For the hysteretic formulation to be robustcomputationally, care must be taken to ensure the differentiability ofthe characteristic curves both within and beyond the turning-pointsaturations where transitions between branches of the curves occur. Twoexample problems involving geologic CO2 storage are simulated withTOUGH2, a multiphase, multicomponent code for flow and transport codethrough geological media. Both non-hysteretic and hysteretic formulationsare used, to illustrate the applicability and limitations ofnon-hysteretic methods.The first application considers leakage of CO2from the storage formation to the ground surface, while the secondexamines the role of heterogeneity within the storageformation.

    In March 2010, the project CoCoCo (incipient COntinent-COntinent COllision) recorded a 650 km long amphibian N-S wide-angle seismic profile, extending from the Eratosthenes Seamount (ESM) across Cyprus and southern Turkey to the Anatolian plateau. The aim of the project is to reveal the impact of the transition from subduction to continent-continent collision of the African plate with the Cyprus-Anatolian plate. A visual quality check, frequency analysis and filtering were applied to the seismic data and reveal a good data quality. Subsequent first break picking, finite-differences ray tracing and inversion of the offshore wide-angle data leads to a first-arrival tomographic model. This model reveals (1) P-wave velocities lower than 6.5 km/s in the crust, (2) a crustal thickness of about 25-30 km and (3) an upper crustal reflection at 5 km depth beneath the ESM. Two landshots on Turkey, also recorded on Cyprus, air gun shots south of Cyprus and geological (Mackenzie et al., 2006) and previous seismic information provide the data to derive a layered velocity model beneath the Anatolian plateau and for the ophiolite complex on Cyprus. Reflections provide evidence for a north-dipping plate subducting beneath Cyprus. The main features of this model are (1) an upper and lower crust with large lateral changes in velocity structure and thickness, (2) a Moho depth of about 45-50 km beneath the Anatolian plateau, (3) a shallow north-dipping subducting plate below Cyprus with an increasing dip and (4) a typical ophiolite sequence on Cyprus with a total thickness of about 14km. The offshore-onshore seismic data complete and improve the information about the velocity structure beneath Cyprus and the deeper part of the offshore tomographic model. Thus, the wide-angle seismic data provide detailed insights into the 2D-geometry and velocity structures of the uplifted and overriding Cyprus-Anatolian plate. Subsequent gravity modeling will be used to check and improve the velocity

    The objective of this work is to study some geological characteristics in a regolith-rock profile by analyzing the distribution of natural radionuclides along the profile by high resolution gamma ray spectrometry. The concentrations of radionuclides reflect some mineralogical characteristics of the rock matrix and also more recent events, such as weathering and erosion. The samples were collected in an abandoned limestone mine, in the city of Sapopema, Paraná State, Brazil. The stratigraphy is represented by an alternation of decimetric limestone layers, bituminous shale and some rhythmite layers. The ratios eTh/K obtained for all samples of the studied profile have equivalent values, indicating similar mineralogical characteristics of their detritic components. The ratio eTh/eU corroborates the fact that regolith samples belong to a much more oxidized environment, favoring the leaching of uranium. These results show that the measurement of radionuclide distribution in rocks and soils may be an important tool for the analysis of geological characteristics, such as mineralogy and oxidizing conditions.

  17. Sources and characteristics of acoustic emissions from mechanically stressed geologic granular media — A review

    Michlmayr, Gernot; Cohen, Denis; Or, Dani

    2012-05-01

    The formation of cracks and emergence of shearing planes and other modes of rapid macroscopic failure in geologic granular media involve numerous grain scale mechanical interactions often generating high frequency (kHz) elastic waves, referred to as acoustic emissions (AE). These acoustic signals have been used primarily for monitoring and characterizing fatigue and progressive failure in engineered systems, with only a few applications concerning geologic granular media reported in the literature. Similar to the monitoring of seismic events preceding an earthquake, AE may offer a means for non-invasive, in-situ, assessment of mechanical precursors associated with imminent landslides or other types of rapid mass movements (debris flows, rock falls, snow avalanches, glacier stick-slip events). Despite diverse applications and potential usefulness, a systematic description of the AE method and its relevance to mechanical processes in Earth sciences is lacking. This review is aimed at providing a sound foundation for linking observed AE with various micro-mechanical failure events in geologic granular materials, not only for monitoring of triggering events preceding mass mobilization, but also as a non-invasive tool in its own right for probing the rich spectrum of mechanical processes at scales ranging from a single grain to a hillslope. We review first studies reporting use of AE for monitoring of failure in various geologic materials, and describe AE generating source mechanisms in mechanically stressed geologic media (e.g., frictional sliding, micro-crackling, particle collisions, rupture of water bridges, etc.) including AE statistical features, such as frequency content and occurrence probabilities. We summarize available AE sensors and measurement principles. The high sampling rates of advanced AE systems enable detection of numerous discrete failure events within a volume and thus provide access to statistical descriptions of progressive collapse of systems

    In order to ensure that a repository for the geological disposal of HLW is isolated from the human environment, underground excavations, including pits and tunnels, must be properly sealed. Effective sealing requires that these excavations are backfilled, and that the Excavation Damage or Disturbed Zone (EDZ), which includes preferential flow paths, must be intersected by sealing plugs. Methods for constructing a full-scale sealing plug and their influence on plug performance were evaluated and confirmed by a Tunnel Sealing Experiment (TSX). This experiment was carried out by an international partnership of the Japan Nuclear Cycle Development Institute (JNC) and Atomic Energy of Canada Limited (AECL). However certain specific roles of the scaling plugs at the scale of the whole repository were not studied. There remain issues to be clarified, notably the effectiveness of sealing plugs in a geological environment with heterogeneous characteristics and the resulting influences of the heterogeneities in performance assessment. Focusing on a geological environment with spatially heterogeneous characteristics, the authors have developed a method for designing the sealing plugs, based on a concept of 'primarily design for closure, secondarily design for construction'. Though the proposed method for designing sealing plugs has presently been developed only at a conceptual level, it indicates the possibility of establishing a repository even in a strongly heterogeneous geological environment that may have been considered previously to be inappropriate for a repository.

    The Department of Energy`s (DOE`s) primary mission in the oil research program is to maximize the economically and environmentally sound recovery of oil from domestic reservoirs and to preserve access to this resource. The Oil Recovery Field Demonstration Program supports DOE`s mission through cost-shared demonstrations of improved Oil Recovery (IOR) processes and reservoir characterization methods. In the past 3 years, the DOE has issued Program Opportunity Notices (PONs) seeking cost-shared proposals for the three highest priority, geologically defined reservoir classes. The classes have been prioritized based on resource size and risk of abandonment. This document defines the geologic, reservoir, and production characteristics of the fourth reservoir class, strandplain/barrier islands. Knowledge of the geological factors and processes that control formation and preservation of reservoir deposits, external and internal reservoir heterogeneities, reservoir characterization methodology, and IOR process application can be used to increase production of the remaining oil-in-place (IOR) in Class 4 reservoirs. Knowledge of heterogeneities that inhibit or block fluid flow is particularly critical. Using the TORIS database of 330 of the largest strandplain/barrier island reservoirs and its predictive and economic models, the recovery potential which could result from future application of IOR technologies to Class 4 reservoirs was estimated to be between 1.0 and 4.3 billion barrels, depending on oil price and the level of technology advancement. The analysis indicated that this potential could be realized through (1) infill drilling alone and in combination with polymer flooding and profile modification, (2) chemical flooding (sufactant), and (3) thermal processes. Most of this future potential is in Texas, Oklahoma, and the Rocky Mountain region. Approximately two-thirds of the potentially recoverable resource is at risk of abandonment by the year 2000.

    As a part of the CyprusArc project, a seismic wide-angle reflection/refraction profiles were carried out in March 2010. The 300 km and 45 km long north-south trending profiles extended from Cihanbeyli in Central Anatolia to Anamur in eastern Mediterranean, Turkey and in southern Cyprus, respectively. The purpose of the project is to observe the impact of the transition from subduction to continent-continent collision of the African plate with the Anatolian plate. The field experiment comprised two land shots (1125 kg explosives) in Turkey and airguns (98 cubic liters) on the Mediterranean sea, beneath Cyprus. 244 stations were installed on land for data acquisition. 77 three-component sensors and 167 vertical-component sensors were installed along ~300 km distances between Cihanbeyli and Anamur with an average spacing of 1.25 km, on Turkey. 24 three-component sensors and 21 vertical component sensors were deployed along 45 km distances on land at southern Cyprus with an average spacing of 1.25 km. To reveal a good data quality, a visual quality check, frequency analysis and filtering were applied to the seismic data. Two land shots on Turkey (also recorded on Cyprus) and airgun shots on the Mediterranean sea beneath Cyprus, geological and previous seismic investigations provide information to derive a layered velocity models beneath from the Anatolian plateau to eastern Mediterranean, Turkey and for the ophiolite complex on Cyprus. After picking observed seismic phases, finite-differences ray tracing of the wide-angle data leads a 2-D crustal P-wave velocity models. The results show moho depth increases from 38 km to 45 km depth along north-south trending profile on Turkey and crustal thinning between south Turkey and Cyprus from 40 km to 36 km. Obtained models were further refined using forward modeling to generate synthetic seismograms for individual shot gathers. Thus, by varying the velocity structure, the theoretical times and amplitudes of the various

    The development of Landscape Typologies in Europe relies upon advances in geospatial tools and increasing availability of digital datasets. Landscape Character Assessment (LCA) is a technique used to classify, describe and understand the combined physical, ecological and cultural characteristics of a landscape. LCA uses a range of data sources to identify and describe areas of common character and can operate at a range of scales i.e.national and regional and local. The paper describes the steps taken to develop an island wide landscape typology for Cyprus, based on the use of GIS and remote sensing tools. The methodology involved integrating physiographical, ecological and cultural information about the Cypriot landscape. Datasets on the cultural attributes (e.g. settlement and field patterns) were not available, so they were created de novo based on information from topographical maps (for settlement dispersion and density) and medium resolution satellite imagery from Google Earth, from which a number of distinctive field patterns could be distinguished. The mapping work is carried out on two levels using a hierarchical approach. The first level at a 1:100, 000 scale has been completed resulting in a map with 17 distinct landscape types. The second level is under way with the view of producing a more detailed landscape typology at 1:50, 000 scale which will incorporate the cultural aspects of the island. This is the first time that such a typology has been produced for Cyprus and it is expected to provide an invaluable tool for landscape planning and management.

    1994-01-01

    All of the hydrogeologic subdivisions within the Edwards aquifer outcrop in Comal County have some porosity and permeability. The most porous and permeable appear to be hydrogeologic subdivision VI, the Kirschberg evaporite member of the Kainer Formation; hydrogeologic subdivision III, the leached and collapsed members, undivided; and hydro- geologic subdivision II, the cyclic and marine members, undivided, of the Person Formation. The two types of porosity in the Edwards aquifer outcrop are fabric selective, which is related to depositional or diagenetic elements and typically exists in specific stratigraphic horizons; and not fabric selective, which can exist in any litho- stratigraphic horizon. Two faults, Comal Springs and Hueco Springs, completely, or almost completely, offset the Edwards aquifer along much of their respective traces across Comal County. Porous and permeable Edwards aquifer limestones are juxtaposed against impermeable upper confining beds along all, or most of their traces across Comal County. These faults could be barriers, or partial barriers, to ground-water flow where the aquifer is offset. In Comal County, the Edwards aquifer is probably most vulnerable to surface contamination in the rapidly urbanizing areas on the Edwards aquifer outcrop. Possible contamination can result from spills, leakage of hazardous materials, or runoff onto the intensely faulted and fractured, karstic limestone outcrops characteristics of the recharge zone.

    Geological and hydrogeological characteristics of the Lozovy ridge (Southern Primorye) are studied, as far as karst phenomena are widely distributed within its boundaries. Water-bearing rocks of the karst water source “Silver Spring” (“Serebryany Klyuch”), which is located near the bottom of the “Bear’s fang” (“Medvezhiy klyk”) cave, are investigated. It is found that karst rocks are presented by calcite (CaCO3), and an accessory mineral is barite (BaSO4). It is determined that among the trace elements forming the composition of carbonate water-bearing rocks the maximum concentrations are typical for Sr, Ba, Fe, Al, Za, Mn, Cu, and Ni. Also, the chemical composition of the waters taken from the “Silver Spring” water source is studied. These waters are fresh, hydrocarbonate, calcium, and weakly alkaline. Among the elements of the spring, such elements as Sr, Ba, Fe, Al, Zn, Mn, Cu, and Ni have the maximum concentration. The other elements have concentrations less than 1 µg/l.

    2015-11-01

    This technical note presents the methods and techniques developed by the Bi-communal Forensic Team (BCFT) of the Committee on Missing Persons in Cyprus (CMP) used to excavate and exhume the remains of missing persons, many of whom were buried in deep wells at sites across the island of Cyprus during the conflict period of the 1960s and 1970s. A total of 493 Turkish Cypriots and 1508 Greek Cypriots were officially reported missing by the two communities as a result of the conflict. Since the team's formation, in 2005, the BCFT has excavated 114 wells, resulting in the recovery of 195 missing individuals from 35 of these well excavations. The standard excavation approach used by the BCFT, especially for deep well recovery, consists of "ramp," "pocket," and "pool" components. These excavation features enable CMP archaeologists to excavate deep wells safely and efficiently while simultaneously permitting time for thorough documentation and unimpeded recovery of human remains. The team uses three variants of this approach to cope with the variety of geological, physical, and hydrological contexts faced in Cyprus' wells, including hard and soft landforms, the presence or absence of water, and limitations imposed by surrounding infrastructure. The "terracing", "double-ramp", and "single-ramp" variations are detailed with respect to the environmental contexts which prescribe their use. The BCFT's general procedures for human remains recovery and standard well safety protocols conclude the article. PMID:26250595

    Information on childhood poisonings in Cyprus is limited. Our objective was to examine the epidemiology of poisonings among children in Cyprus. All children up to 15 years of age admitted for poisoning to the Archbishop Makarios Hospital in Nicosia, Cyprus between 2005 and 2008 were included in our study. All hospital poisoning records were reviewed. A total of 257 children were admitted for poisoning. The mean age of children was 3.1 years, of which 83.7% were below the age of 5 years old, while 53% were boys. The poisoning hospitalizations accounted for about 3% of all admissions to the pediatric department during the study period (4 years). The annual cumulative incidence of childhood poisoning hospitalizations was 116 per 100,000 children. Medications accounted for 46.1% of all poisonings, the most frequent cause being paracetamol (9.8%), cardiovascular medications (5.3%), antitussive medications (4.5%), and other painkillers (4.1%). Another 37.6% of hospitalizations involved household products such as household cleaning products (11.8%), petroleum products (11.0%), and rodenticides (5.7%). Among children who ingested petroleum distillates, 55.6% developed clinical symptomatology. The vast majority of cases were accidental (93.8%). Suicidal cases involved children 8-14 years old, mainly girls, and the most frequent poisoning ingested was paracetamol (46.7%). Poisoning hospitalizations represent an important cause of morbidity among children in Cyprus. Preventive strategies should include the education of caregivers on the handling of medications and household products as well as legislation requiring child-resistant packaging for all medications and household products including petroleum distillates.

    Cyprus, a European Union member state, is a small island in the Mediterranean with a population approaching 900,000 people. Cancer is the second leading cause of death; more therapeutic options for any patient with the disease are available in a central oncology centre in the capital of the island (Nicosia) and fewer therapeutic options (e.g. chemotherapy and hormone therapy only) in a few other public hospitals. Palliative care is offered in several hospices and hospitals, although the field needs improvement. With regards to screening, a national breast cancer screening programme has been in place countrywide since 2007 and is offered free of charge to women between the ages of 50 and 69 years, while colorectal and prostate cancer screening is performed on an individual basis (a pilot programme for colorectal cancer screening was recently initiated). Genetic testing is available for breast and colon cancer. To improve understanding of the causes of cancer in the country, a cancer research centre was established in 2010 (Mediterranean Centre for Cancer Research). Recent epidemiologic work has revealed increasing cancer trends in Cyprus; prostate cancer is the most common in men and breast cancer is the most common in women. Interestingly, thyroid cancer incidence in women has been rising from 1998 to 2008. Cancer of the colon and rectum is also on the rise affecting both sexes. Overall, cancer incidence in Cyprus is lower than other EuroMed countries with similar lifestyle and geography. PMID:24678344

    Oligocene magmatic activity in the Biga Peninsula (NW-Anatolia) produced widespread volcano-plutonic complexes. The study region, where in north of the Evciler village in the middle of Biga Peninsula includes these igneous assemblages. In this study, the petrographic and geochemical characteristics of igneous rocks in the region were investigated as well as the geological locations. The magmatic rocks are classified as 6 different units using their lithostratigraphical properties. The volcanism in the region starts with basaltic andesite lava including basalt dykes in the Lower Oligocene. In the Upper Oligocene, the evolved magma by crustal contamination produced commonly dacitic and andesitic lavas. The volcanism continued with andesitic lavas which had significant alterations in the region during this period. Evciler pluton including granite and granodiorite composition with shallow intrusive, was located with the related volcanism at the same time. The volcanic products, i.e. andesitic and trachydacitic lavas, was completed in the interval between Upper Oligocene and Lower Miocene. The post-collisional Oligocene sequence is associated with calc-alkaline composition and it has middle, high-K. Trace and rare earth elements (REE) diagrams show the enrichment in both large-ion lithophile elements (LILE) and light rare earth elements (LREE) with respect to the high field strength elements (HFSE), and a significant increment in heavy rare earth element consumption (HREE). The features of major, trace and rare earth elements of plutonic and volcanic rocks and the compositional variations of Oligocene volcanic group indicate increasing amounts of partial melting, crustal contamination and/or assimilation. The Oligocene post-collisional volcanism in Biga Peninsula points out the lithospheric mantle source enriched by subduction which controlled by slab break-off and lithospheric delamination.

    Compared to the Earth the geologic nature of the lunar regolith is quite distinct. Even though similar minerals exist on the Earth and Moon, they may have very different properties due to the absence of chemical modification in the lunar environment. The engineering properties of the lunar regolith reflect aspects of the parent rock and the consequences of hypervelocity meteor bombardment. On scales relevant to machinery and chemical processing for In-Situ Resource Utilization, ISRU (such as water production), the lunar regolith compositional range is much more restricted than terrestrial material. This fact impacts predictions of properties required by design engineers for constructing equipment for lunar use. In this paper two examples will be covered. 1) Abrasion is related to hardness and hardness is a commonly measured property for both minerals and engineering materials. Although different hardness scales are routinely employed for minerals and engineering materials, a significant amount of literature is available relating the two. As one example, we will discuss how to relate hardness to abrasion for the design of lunar equipment. We also indicate how abundant the various mineral phases are and typical size distributions for lunar regolith which will impact abrasive nature. 2) Mineral characteristics that may seem trivial to the non-geologist or material scientist may have significant bearing on ISRU processing technologies. As a second example we discuss the impact of traces of fluoride, chloride, and hydroxide, water, carbon dioxide, and sulfur species which can radically alter melting points and the corrosive nature of reaction products thereby significantly changing bulk chemistry and associated processing technologies. For many engineering uses, a simulant's fidelity to bulk lunar regolith chemistry may be insufficient. Therefore, simulant users need to engage in continuing dialogue with simulant developers and geoscientists.

    Organic-rich shales spanning in age from Pre-Cambrian to Quaternary were widely deposited in China. This paper elaborates the geology and unique characteristics of emerging and potential hydrocarbon-bearing shales in China. The Pre-Cambrian Sinian Doushantuo to Silurian black marine shales in the intra-shelf low to slope environments were accumulated in South China and Tarim Platform in Northwest China. These marine shales with maturity (Ro) of 1.3-5% are in dry gas window. During Carboniferous to Permian, the shales associated with coal and sandstones were mainly deposited in coastal swamp transitional setting in north China, NE China, NW China and Yangtze platform in South China. These transitional shales are generally clay rich and are potential gas-bearing reservoirs. Since Middle Permian, the lacustrine shales with total carbon content (TOC) up to 30% and Ro mainly in oil window are widely distributed in all the producing basins in China. The lacustrine shales usually have more clay mineral content than marine shales and are characterized by rapid facies change and are interbedded with carbonates and sandstone. The high quality shale reservoir with high TOC, hydrocarbon content and brittle minerals content is usually located at transgressive systems tract (TST) to early highstand systems tract (EHST) interval deposited in anoxic depositional setting. Recent commercial shale gas production from the Silurian Longmaxi marine shale in the southeastern Sichuan Basin, preliminary tight oil production associated with lacustrine hydrocarbon-bearing shale intervals and hydrocarbon shows from many other shales have proven the hydrocarbon-bearing shales in China are emerging and potential shale gas and tight (shale) oil plays. Tectonic movements could have breached the early hydrocarbon accumulation in shales and tectonically stable areas are suggested to be favorable prospects for China shale plays exploration and production.

    Identification of hepatitis B virus (HBV) strains and understanding of molecular epidemiological characteristics are important for the effective surveillance of HBV infections. Genotype D is dominant in studies performed in Turkey but it is known that cases infected with genotypes A, E, G and H also exists. In contrast, there are no data regarding the molecular epidemiologic characteristics of the HBV in Northern Cyprus. The aim of this study was to determine the distribution of genotypes and subgenotypes of HBV among the people living, educating and working in Northern Cyprus. A total of 160 cases (1.2%) who were HBsAg seropositive out of 13.892 subjects admitted to Nicosia, Near East University Hospital microbiology laboratory for the routine control and to blood center for donor screening tests between November 2011 to September 2014, were included in the study. HBV-DNA levels in the HBsAg positive cases were detected by real-time polymerase chain reaction and genotypes/subgenotypes were determined by sequence analysis of the viral pol gene (reverse transcriptase [rt] region, between 80-250. aminoacids). Sixty samples (60/160, 37.5%) were excluded from sequencing analysis due to negative and/or very low (< 30 IU/ml) HBV-DNA levels, so 100 samples were included in sequence analysis. Ninety-six of those cases (13 female, 87 male; mean age: 35.51 ± 12.88 years) were anti-HBc IgG, 95 were anti-HBe and five were HBeAg positive, with a mean HBV-DNA level of 5.36 x 10(6) ± 3.58 x 10(7) IU/ml. As 32 (32%) samples yielded HBV-DNA level below the threshold of 1000 IU/ml, sequence analyses were unsuccesful, eventually 68 (68/160, 42.5%) samples could be phylogenetically analyzed. The distribution of HBV genotypes/subgenotypes were found as follows: 48 were (70.6%) D/D1; four were (5.9%) D/D2; one was (1.5%) D/D3, five were (7.4%) A/A1, two were (2.9%) A/A2 and eight were (11.8%) genotype E. Among the most frequent D1 strains, 60.4% (29/48) cases were from Turkish; single

    Background The concept of organizational culture is important in understanding the behaviour of individuals in organizations as they manage external demands and internal social changes. Cyprus healthcare system is under restructuring and soon a new healthcare scheme will be implemented starting at the Primary Healthcare (PHC) level. The aim of the study was to investigate the underlying culture encountered in the PHC setting of Cyprus and to identify possible differences in desired and prevailing cultures among healthcare professionals. Methods The population of the study included all general practitioners (GPs) and nursing staff working at the 42 PHC centres throughout the island. The shortened version of the Organizational Culture Profile questionnaire comprising 28 statements on organizational values was used in the study. The instrument was already translated and validated in Greek and cross-cultural adaptation was performed. Participants were required to indicate the organization’s characteristic cultural values orientation along a five-point Likert scale ranging from “Very Much = 1” to “Not at all= 5”. Statistical analysis was performed using SPSS 16.0. Student t-test was used to compare means between two groups of variables whereas for more than two groups analysis of variance (ANOVA) was applied. Results From the total of 306 healthcare professionals, 223 participated in the study (72.9%). The majority of participants were women (75.3%) and mean age was 42.6 ± 10.7 years. Culture dimension “performance orientation” was the desired culture among healthcare professionals (mean: 1.39 ± 0.45). “Supportiveness” and “social responsibility” were the main cultures encountered in PHC (means: 2.37 ± 0.80, 2.38 ± 0.83). Statistical significant differences were identified between desired and prevailing cultures for all culture dimensions (p= 0.000). Conclusions This was the first study performed in Cyprus assessing organizational culture in

    SummaryCyprus being a Mediterranean island with long dry summers and mild winters suffers from water deficiency and over exploitation of its water resources. Groundwater in Cyprus is a valuable natural resource as approximately 50% of the total water needs come from underground water supplies. According to the Directive 118/2006/EC, groundwater should be protected from deterioration and chemical pollution, this is particularly important for groundwater dependent ecosystems and for the use of groundwater as a water supply for human consumption. During 2007 to 2009, as part of a national monitoring programme, 84 boreholes were sampled in Cyprus and subsequently analysed for total arsenic by inductively coupled plasma mass spectrometry (ICP-MS). The groundwater concentrations ranged from <0.3 to 41 μg/L As. Several boreholes located in a rural farming district near Nicosia had concentrations above the World Health Organisation (WHO) Drinking Water Guideline limit of 10 μg/L As. Evaluation of the groundwater sampling procedure for boreholes provided data recommending that water samples should be collected after an initial borehole washout for 5 min. Further sampling of these boreholes in 2010, revealed total arsenic concentrations of <0.3-64.2 μg/L As, with the predominant arsenic species (determined using a novel field-based methodology) being arsenate (AsV). The maximum total arsenic concentration is 6-fold higher than the WHO Drinking Water Guideline limit (10 μg/L As) and approximately half of the United Nations Food and Agriculture Organisation (UN-FAO) irrigational limit of 100 μg/L As.

    Almost every year, localised and in some cases more widespread floodings affect parts of Cyprus, causing damages to properties destruction to infrastructure and housing and sometimes the loss of human life. Various factors such as the meteorological situation and type and intensity of precipitation, the geomorphology, the geology and the human intervention to geomorphology are responsible for flood events. In the present study, only the meteorological situation and the associated mechanisms are examined in an attempt to gain the essential knowledge for improvement of local weather forecasts. The study period covers a thirteen-year period, from 1994 to 2006, in which 43 cases of flooding were reported, mainly over urbanized areas. The dominant favorable weather conditions for flood events are either the existence of a depression or weather conditions of convectional type. According to these two factors, the flood events were classified into two categories; the "instability'' category which includes isolated flood events of short duration, and the "depression'' category which includes widespread flood events of long duration.

  3. Characteristics of water-well yields in part of the blue ridge geologic Province in Loudoun County, Virginia

    Loudoun County, Virginia, which is located about 50 km to the west of Washington, DC, was the site of intensive suburban development during the 1980s and 1990s. In the western half of the county, the source of water for domestic use has been from wells drilled into the fractured crystalline bedrock of the Blue Ridge Geologic Province. A comprehensive digital database that contains information on initial yield, location, depth, elevation, and other data for 3651 wells drilled in this 825.5-km2 area was combined with a digital geologic map to form the basis for a study of geologic and temporal controls on water-well yields. Statistical modeling procedures were used to determine that mean yields for the wells were significantly different as a function of structural setting, genetic rock type, and geologic map unit. The Bonferroni procedure then was used to determine which paired comparisons contributed to these significant differences. The data were divided into 15 temporal drilling increments to determine if the time-dependent trends that exist for the Loudoun County data are similar to those discovered in a previous study of water-well yields in the Pinardville 7.5-min quadrangle, New Hampshire. In both regions, trends, which include increasing proportions of very low yield wells and increasing well depths through time, and the counterintuitive result of increasing mean well yields through time, were similar. In addition, a yield-to-depth curve similar to that discovered in the Pinardville quadrangle was recognized in this study. Thus, the temporal model with a feed-forward-loop mechanism to explain the temporal trends in well characteristics proposed for the New Hampshire study appears to apply to western Loudoun County. ?? 2001 International Association for Mathematical Geology.

    Underground nuclear explosions (UNEs) produce anthropogenic isotopes that can potentially be used in the verification component of the Comprehensive Nuclear-Test-Ban Treaty. Several isotopes of radioactive xenon gas have been identified as radionuclides of interest within the International Monitoring System (IMS) and in an On-Site Inspection (OSI). Substantial research has been previously undertaken to characterize the geologic and atmospheric mechanisms that can drive the movement of radionuclide gas from a well-contained UNE, considering both sensitivities on gas arrival time and signature variability of xenon due to the nature of subsurface transport. This work further considers sensitivities of radioxenon gas arrival time and signatures to large variability in geologic stratification and generalized explosion cavity characteristics, as well as compares this influence to variability in the shallow surface.

    The island of Cyprus represents an excellent site to assess quantitatively petrologic clastic response to actively obducting oceanic sources in order to define an actualistic reference for ophiolite provenance, in terms of framework composition and heavy mineral suites. An improved methodology, an extension of the classic ternary QFL logic to include a wider spectrum of key indexes and ratios, provides an accurate synthesis of modal data and allows differentiation of three main petrographic provinces and at least seven subprovinces. Diagnostic signatures of detritus from various levels of an oceanic lithospheric source, and criteria for distinguishing provenance from suprasubduction versus mid-oceanic ophiolites are also outlined. Modern sands derived from the Troodos Ophiolite contain variable proportions of largely pelagic carbonate to chert, boninite to basalt, diabase to metabasite, plagiogranite to gabbroic, and cumulate grains supplied from progressively deeper-seated levels of the multilayered oceanic crust. Dense minerals are mainly clinopyroxenes (diopside), prevailing over orthopyroxenes (enstatite, hypersthene, clinoenstatite), hornblende, tremolite/actinolite, and epidote. Where serpentinized mantle harzburgites have been unroofed, detritus is markedly enriched in cellular serpentinite grains and enstatite, with still negligible olivine and spinel. Sedimentaclastic sands dominated by chert (Mamonia Province) or carbonate grains (Kyrenia Province) are deposited along the southern and northern shores of the island, respectively. Compositions of Cyprus sands are virtually unaffected by climatic, sedimentary, or anthropic processes; recycling of sandstones from foreign sources is a major process only in the Karpaz Peninsula. Petrographic analysis also provides an independent mean to identify prevalent directions of longshore sand transport. PMID:10736270

    There are at least 7 different stratigraphic columns in Cyprus. Despite a consensus about a last stratigraphy terminology to use, the limits of several stages and unconformities are still under debate. Here are some of the difficulties to establish a synthetic stratigraphic column of Cyprus: - A large longitudinal and latitudinal heterogeneous in the localisation of deposits that are affected by important sedimentary and/or biostratigraphic hiatus. -Some sedimentary series are difficult to date, this is the case notably for the Akamas sandstones. These sandstones are barren and belong to the Mamonia complex, which makes it difficult to locate them in the general stratigraphy of Cyprus. -The strong tectonic setting of Cyprus could be responsible for the migration of center-deposits and formation of hiatus. Consequently, the establishment of a lithostratigraphic column requires a sequential analysis rarely used. -The identification of analogue facies in different basins must be realized through systematic datation in order to avoid mistakes in attributing an age to a formation, which often occurs in Cyprus. An accurate study of the bibliography, associated to new field observations and completed by new chronological data allow us to suggest a new stratigraphic chart. This stratigraphic column starts by the oldest deposits of Cyprus and finishes by the Quaternary deposits. This chart also allows to retrace from East to West several geodynamic events of Cyprus that are recorded in the sedimentary deposits since the Triasic Period.

    The Tertiary regressive sedimentary succession which forms the sedimentary cover of the Troodos Ophiolic Massif has been studied in the Psematismenos-Maroni Basin (PMB) located in southern Cyprus. Identification of key surfaces, morphologies, and sedimentary facies permit to propose a new interpretation of the geologic history of this basin. The series of unconformity surfaces are conforted by numerous new datings, and they are related to tectonic, eustatic, and biostratigraphic hiatuses. This eventually leads to a new geologic vision of the Psematismenos-Maroni Basin from the Neogene Pakhna formation up to the first alluvial deposits of the Quaternary. In the meantime, and for what concerns the Messinian salinity crisis; similarities and differences from the 2008 Messinian consensus (Lofi et al. 2008) are highlighted.

    The Edwards aquifer is the primary source of potable water for the San Antonio area in south-central Texas. The Knippa Gap was postulated to channel or restrict flow in the Edwards aquifer in eastern Uvalde County, and its existence was based on a series of numerical simulations of groundwater flow in the aquifer. To better understand the function of the area known as the Knippa Gap as it pertains to its geology and structure, the geologic framework, structure, and hydrogeologic characteristics of the area were evaluated by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers-Fort Worth District. The principal structural feature in the San Antonio area is the Balcones Fault Zone, which is the result of Miocene age faulting. In Medina County, the faulting of the Balcones Fault Zone has produced a relay-ramp structure that dips to the southwest from the Edwards aquifer recharge zone and extends westward and below land surface from Seco Creek. Groundwater flow paths in the Edwards aquifer are influenced by faulting and geologic structure. Some faults act as barriers to groundwater flow paths where the aquifer is offset by 50 percent or more and result in flow moving parallel to the fault. The effectiveness of a fault as a barrier to flow changes as the amount of fault displacement changes. The structurally complex area of the Balcones Fault Zone contains relay ramps, which form in extensional fault systems to allow for deformation changes along the fault block. In Medina County, the faulting of the Balcones Fault Zone has produced a relay-ramp structure that dips to the southwest from the Edwards aquifer recharge zone. Groundwater moving down the relay ramp in northern Medina County flows downgradient (downdip) to the structural low (trough) from the northeast to the southwest. In Uvalde County, the beds dip from a structural high known as the Uvalde Salient. This results in groundwater moving from the structural high and downgradient (dip

    The southern rim of the Isidis basin contains one of the highest densities of valley networks, several restricted paleolake basins, and the stratigraphically lowest (oldest) terrain on Mars. Geologic mapping in Viking, MGS/MOC, and MOLA data, Odyssey/ THEMIS data, and other multispectral data products supports the presence of extensive fans of debris and sediments deposited along the inner rim of the Isidis basin where large valleys enter the lowlands. Additional processes subsequent to the period of intense fluvial activity, including mass flow analogous to some glacial processes, have contributed to the materials accumulated on the margins of the Isidis basin. These have occurred along preexisting channels and valleys at the termini of major channels where they enter the plains along the highland-lowland boundary. If the abundant valley networks in highland terrains are the result of runoff accompanied by saturated groundwater flow, as has been suggested in previous studies of ancient fluvial highland terrains, then the extreme age and abundance of early valley networks in the Libya Montes highland rocks should have resulted in deposition of materials that record evidence for the long-term presence of water in the form of aqueous alteration of polycrystalline constituents. The material deposited along the basin margin is likely to consist of ancient altered highland rocks in several physical states (weathered, rounded, and angular) exposing both weathered and altered surfaces, and exposures of alteration profiles in fractured faces and unweathered material from rock interiors. Debris fans shed off the southern rim of Isidis Planitia should contain materials that have experienced possible saturated groundwater flow, residence within paleolake basins, and derivative materials deposited during the most fluvially intensive part of Martian geologic history. Many of these materials have also been reworked by ice-related processes. In situ measurements of the ancient

    The continental slope of the Gulf Basin covers more than 500,000 sq km and consists of smooth and gently sloping surfaces, prominent escarpments, knolls, intraslope basins, and submarine canyons and channels. It is an area of extremely diverse topographic and sedimentologic conditions. The slope extends from the shelf break, roughly at the 200 m isobath, to the upper limit of the continental rise, at a depth of 2800 m. The most-complex province in the basin, and the one of most interest to the petroleum industry, is the Texas-Louisiana slope, occupying 120,000 sq km and in which bottom slopes range from < 1 deg to > 20 deg around the knolls and basins. The near-surface geology and topography of the slope are functions of the interplay between episodes of rapid shelf-edge and slope progradation and contemporaneous modification of the depositional sequence by diapirism. Development of discrete depo-centers throughout the Neogene results in rapid shelf-edge progradation, often in excess of 15-20 km/my. This rapid progradation of the shelf edge leads to development of thick wedges of sediment accumulation on the continental slope. Oversteeping, high pore pressures in rapidly deposited soft sediments and changes in eustatic sea level cause subaqueous slope instabilities such as landsliding and debris flows. Large scale features such as shelf edge separation scars and landslide related canyons often results from such processes.

    The Ticona Channel is located in north-central Illinois and occurs in Grundy, LaSalle, and Putnam counties. It is a buried bedrock valley that served as the principal paleodrainage system in north-central Illinois during the Illinoian and pre-Illinoian. This study focused on the part of the Ticona Channel within the Leonore 7.5??? Quadrangle. The geometry and stratigraphy of sediments that fill the Ticona Channel were investigated using high-resolution, shallow seismic reflection profiling, traditional field geologic mapping techniques, borehole data, and water-well-log data. The valley is about 2 km (1 mi) wide and approximately 60 m (200 ft) deep. The U-shape channel is straight, trends east-west, and has only one mappable tributary. The valley is carved into the Pennsylvanian Carbondale Formation in the eastern part of the study area; it has incised into the Ordovician Prairie du Chien Group in the west. At its base, the Ticona Channel is filled with the Pearl Formation, which is coarse-grained sand and gravel that was deposited during the Illinoian glaciation. The Pearl Formation is overlain by Illinoian till of the Glasford Formation and is capped by Wedron Group sediments from the Wisconsinan stage. Copyright ?? 2007.

  14. Geologic Sequestration of Carbon Dioxide: Socioeconomic Characteristics and Landowner Acceptance of Carbon Sequestration Sites

    NASA Astrophysics Data System (ADS)

    Parfomak, Elizabeth C.

    This study explores public acceptance of carbon dioxide sequestration sites through a mail survey of 4,001 landowners in central Illinois and Indiana, a region with high sequestration potential and recent siting proposals for FutureGen (an integrated power plant and sequestration demonstration project). The individuals sampled in this study include landowners both informed and uninformed about carbon sequestration, comparing groups based on ecological concern, economic conditions, views about the energy industry, environmental justice, familiarity with sequestration, and demographics. Of the survey respondents, 27% reported an understanding of carbon sequestration prior to receiving the survey, 2.5 times more than would be expected in the general U.S. population. Overall, 47% of survey respondents would oppose a local sequestration site while 30% would support one. The results suggest that greater familiarity with geologic sequestration has little influence on local site acceptance. Multivariate analysis found that landowner acceptance of sequestration sites derives primarily from gender, concern for the local environment, trust in government, experience with industrial activity, and belief in the potential of conservation/renewables. Because views on these issues are persistent, it may be difficult to overcome landowner opposition through education. Policy makers may, therefore, need to lower expectations for sequestration deployment in the United States and revisit other options for meeting the nation's CO2 emissions goals.

  15. Combined geophysical, geochemical and geological investigations of geothermal reservoir characteristics in Lower Saxony, Germany

    2012-04-01

    The North German basin provides a significant geothermal potential, although temperature gradients are moderate. However, deep drilling up to several thousand meters is required to reach temperatures high enough for efficient generation of geothermal heat and electric power. In these depths we have not much information yet about relevant physical properties like porosity or permeability of the rock formations. Therefore the costs of developing a geothermal reservoir and the risk of missing the optimum drilling location are high. The collaborative research association "Geothermal Energy and High Performance Drilling" (gebo) unites several universities and research institutes in Lower Saxony, Germany. It aims at a significant increase of economic efficiency by introducing innovative technology and high tech materials resisting temperatures up to 200 °C in the drilling process. Furthermore, a better understanding of the geothermal reservoir is essential. gebo is structured into four main fields: Drilling Technology, Materials, Technical Systems and Geosystem. Here, we show the combined work of the Geosystem group, which focuses on the exploration of geological fault zones as a potential geothermal reservoir as well as on modeling the stress field, heat transport, coupled thermo-hydro-mechanical processes, geochemical interactions and prediction of the long-term behavior of the reservoir. First results include combined seismic and geoelectric images of the Leinetalgraben fault system, a comparison of seismic images from P- and S-wave measurements, mechanical properties of North German rocks from field and laboratory measurements as well as from drill cores, seismological characterization of stimulated reservoirs, a thermodynamic "gebo" database for modeling hydrogeochemical processes in North German formation waters with high salinity and at high temperatures, stress models for specific sites in northern Germany, and modeling results of permeability and heat transport

    2010-12-01

    Cyprus is a Mediterranean island divided into two political sections. For political agreement to be possible between the North (Turkish) and South (Greek), Cyprus should give full consideration to citizenship education at schools with the aim of transmitting shared values and helping students become EU citizens. In this research, two citizenship textbooks which were designed and used for eighth grade level were examined using content analysis. One was a Greek book used in South Cyprus and the other one was a Turkish book used in North Cyprus. Both textbooks were prepared and published in the respective mainland states (Greece and Turkey) and reflected the culture of these countries. Although Turkey is a candidate state for the European Union, the Turkish book focuses on empowering local citizen identity in the nation state and does not discuss broader issues related to global citizenship. By contrast, the Greek textbook covers both national and global issues concerning citizenship. Silman and Çağlar suggest that North and South Cyprus should design their own citizenship books to promote the concepts of interdependence, multiculturalism, democracy, human rights and respect for cultural diversity. The researchers believe that this could facilitate a possible political agreement between the two sides.

    An integrated geophysical ground survey was conducted on an airborne electromagnetic (EM) anomaly located in Kakamega forest of Western Kenya. The purpose of the study was to establish the existence of massive sulphides and identify suitable optimal geophysical method(s) for the investigation of similar anomalies. The study was also expected to provide information on the geological and geophysical characteristics of the deposit. Field work involved electromagnetic methods: Vertical Loop (VLEM), Horizontal Loop (HLEM), TURAM EM and potential field methods: gravity and magnetics. Geochemical sampling was carried out concurrently with the geophysical survey. All the geophysical methods used yielded good responses. Several conductors conforming to the strike of the geology were identified. TURAM EM provided a higher resolution of the conductors compared to VLEM and HLEM. The conductors were found to be associated with positive gravity anomalies supporting the presence of bodies of higher density than the horst rock. Only the western section (west of 625W) of the grid is associated with strong magnetic anomalies. East of 625W strong EM and gravity anomalies persist but magnetic anomalies are weak. This may reflect variation in the mineral composition of the conductors from magnetic to non-magnetic. Geochemical data indicates strong copper anomalies (upto 300 ppm) over sections of the grid and relatively strong zinc (upto 200 ppm) and lead (upto 100 ppm) anomalies. There is a positive correlation between the location of the conductors as predicted by TURAM EM and the copper and zinc anomalies. A test drill hole proposed on the basis of the geophysical results of this study struck massive sulphides at a depth of 30m still within the weathered rock zone. Unfortunately, the drilling was stopped before the sulphides could be penetrated. The drill core revealed massive sulphide rich in pyrite and pyrrhotite. An attempt has been made to compare characteristics of the

    In the 80s, the POEM (Physical Oceanography of the Eastern Mediterranean) cruises in the Levantine Basin first revealed the presence of a very pronounced dynamical structure off Cyprus: The Cyprus Warm Core Eddy. Since then, a large amount of data have been collected thanks to the use of autonomous oceanic gliders (+8000 profiles since 2009). Part of those profiles were carried out in the upper layers down to 200 m, and we take benefit of a novel approach named ITCOMP SOM that uses a statistical approach to extend them down to 1000 m (see [1] for more details). This dataset have a particularly good spatio-temporal coverage in 2009 for about a month, thanks to simultaneous deployments of several gliders (up to 6). In this study, we present a set of 3D reconstruction of the dynamical and hydrographical characteristics of the Warm Core Cyprus Eddy between 2009 and 2015. Moreover, chlorophyll-a fluorescence data measured by the gliders give evidence to strong vertical velocities at the edge of the eddy. We discuss possible mechanisms (frontogenesis, symmetric instability) that could generate such signals and provide an assessment of the role of this peculiar circulation feature on the circulation and biogeochemistry of the Levantine basin.

    The geometry and basic characteristics (length, density/intensity, aperture, and porosity) of fractures (joints) have been defined recently for a number of Middle East reservoirs. The factors that determine the occurrence of natural, open, permeable fractures within Middle East reservoirs are nature and degree of folding and/or faulting, in-situ stresses, and changes in rock properties such as porosity, lithology, and especially shaliness. Fracture distribution and orientation within Mesozoic Arabian/Persian Gulf halo-kinetic structures is important to reservoir development and modeling, although the fractures generally only assist productivity. In the deeper Paleozoic reservoirs, fractures become increasingly important. Fractures are best developed in relatively anhydrite free, low porosity, dolomite facies, and with few exceptions their orientation is related to regional trends, only slightly modified by local tectonic features. Exploration for deep-fracture reservoirs needs to consider that the probability of uncemented fractures will be present only where the timing of hydrocarbon migration was close in timing to fracturing. Examination of fractured reservoirs in the Zagros-Bitlis orogenic belt from Turkey through Syria, Iraq, Iran and the northern Emirates demonstrates that the fracturing is dominantly related to folding, with only minor karst fracturing or fault-related fracturing, whereas the fractures in the Gulf of Suez are closely related to the faulting history with some of the most intense fracturing of the low-porosity Eocene limestones forming a fracture reservoir near fault zones. Studies of basement fracturing reveals that decreases in fracture apertures generally accompanies increases in fracture density. The distribution of fractures within the northern Sinai closely fit a wrench-tectonic model, where the greatest density and largest apertures occur in the dolomitic facies and have an orientation parallel to synthetic faulting of the wrench system.

  20. The fate of salt in the Cyprus subduction zone

    2014-05-01

    The area between Cyprus and Hecataeus Rise to the north and Eratosthenes Seamount (ESM) further south is presently accommodating plate tectonic convergence between Africa and Anatolia. A number of studies have focused on the convergence history, especially after drilling close to the plate boundary in the course of ODP Leg 160. Even though drilling at Site 968 has reached late Messinian Lago Mare deposits, little information on deeper trench strata exist, owing to limited penetration of previously published seismic data. Here we show results from bathymetric data and a dense grid of seismic lines collected during research cruises MSM14/2 and MSM14/3 in 2010 across the Cyprus trench, shedding new light on the tectonostratigraphic evolution of the plate boundary. Evaporites of locally more than 1.5 km thickness occupy the northern trench area. Between Cyprus and ESM evaporites are heavily deformed and appear to be thrust southward over Pliocene-Quaternary strata. Thus significant post-Messinian tectonic shortening at the plate boundary was accommodated by allochthonous salt advance towards the ESM which is currently being thrust beneath the island of Cyprus. Such observations may provide an example of how salt efficiently escapes the subduction cycle. In contrast, evaporites between ESM and Hecataeus Rise have not experienced sufficient shortening for initiating allochthonous salt advance, even though compression-related thickening is clearly evident. The observed pattern of intensively deformed salt between Cyprus and ESM and moderately deformed evaporites in the eastern trench area is believed to reflect a predominately N-S-oriented post-Messinian convergence direction. Such implications raise the question about a fairly recent coupling between the motion of Cyprus and Anatolia. Along the entire study area, the southward salt limit coincides with the seafloor stepping down towards the ESM, suggesting thickening and ESM-directed advance of the evaporites to have

    This paper reviews the status of women in science, physics in particular, in Cyprus. We describe the development of physics in the country, focusing on the contributions and participation of women. We present statistical data for the last several years, reviewing the percentage of women who are pursuing physics as a subject of study or as a profession. We report the gender ratios at different career stages and find that while women are well represented in undergraduate studies, female physicists are underrepresented in senior positions. We discuss factors that might affect the career evolution of women in physics in Cyprus.

    The remote sensing of laser-induced uranyl ion fluorescence is examined as a potential indicator of uranium occurring in geologic materials at the earth's surface. The lifetime and brightness of the fluorescence from a wide variety of rocks, minerals, and soils are reported. The distinctive characteristics of uranyl ion absorption and fluorescence were observed in diverse geologic materials such as chalcedonies and opals containing 15-3000 ppm of uranium and in surface coatings of uranyl minerals such as metaautunite, liebigite, and an-dersonite. The conditions which permit the excitation and selective detection of uranyl ion fluorescence from such targets are described. PMID:20309303

    2010-01-01

    The U.S. Geological Survey, in cooperation with the San Antonio Water System, developed a geodatabase of geologic and hydrogeologic information for selected wells penetrating the Austin Group in central Bexar County, Texas. The Austin Group functions as an upper confining unit to the Edwards aquifer and is the thickest and most permeable of the Edwards aquifer confining units. The geologic and hydrogeologic information pertains to a 377-square-mile study area that encompasses central Bexar County. Data were compiled primarily from drillers' and borehole geophysical logs from federal, State, and local agencies and published reports. Austin Group characteristics compiled for 523 unique wells are documented (if known), including year drilled, well depth, altitude of top and base of the Austin Group, and thickness of the Austin Group.

    Land subsidence is a major worldwide hazard, and causes many problems including: damage to public facilities such as bridges, roads, railways, electric power lines, underground pipes; damage to private and public buildings; and in some cases of low-lying land, can increase the risk of coastal flooding from storm surges and rising sea-levels. The island of Cyprus is famous for its complex geology, particularly in the southwest part of the island. Deposits of massive breccias (melange) are widely exposed in the Paphos District situated between the Troodos Mountains and the sea. These deposits are rich in clay minerals that are prone to landslide phenomena. With its global coverage and all-weather imaging capability, Interferometric SAR (InSAR) is revolutionizing our ability to image the Earth's surface and the evolution of its shape over time. In this paper, an advanced InSAR time series technique, InSAR TS + AEM, has been employed to analysed C-band ERS and Envisat data collected over southwest Cyprus during the period from 1992 to 2010. Our InSAR time series results suggest that: (1) a total number of 274,619 coherent pixels with a density of 46 points per squared km were detected in the area of interest; and (2) clear surface displacements can be observed in several areas. The combination of archived ESA SAR datasets allows a long record (~18 years) of historic deformation to be measured over a large region. Ultimately this should help inform land managers in assessing land subsidence and planning appropriate remedial measures.

    The relationship between the characteristics of seismic waves in the Western Caucasus and the geological-tectonic structure of the region is studied for identifying the specificity of seismic propagation in the mountainous regions with a complicated geological structure and forecasting the characteristics of the propagation from the geological and tectonic data. The interpretation is presented for the estimates of the Q-factor of the medium ( Q( f) ~ 55 f 0.9 in the region of Sochi and Q( f) ~ 90 f 0.7 in the region of Anapa), seismic wave enhancement in the upper crustal layers ( A( f) ~ 1), and peak ground acceleration residuals, which were previously determined from the records of the local earthquakes and show the distributions of local variations in the parameters of seismic wave radiation and propagation. The obtained characteristics are interpreted in the context of the up-to-date information about the tectonic, geological, and deep structure of the epicentral zones in the Western Caucasus and neighboring territory of the Black Sea. The discrepancies revealed in the low-frequency behavior of the Q-factor in the vicinities of Sochi and Anapa is accounted for by the spatial scale and character of tectonic dislocations of the rocks in these regions. The local variations in the parameters of seismic radiation and propagation are probably related to the geological features of the region such as the fault structures, including the thrusts, shatter zones, oblique seismic boundaries, variations in the thickness and consolidation of the sedimentary cover, as well as the peculiarities in the structure and material composition of the basement.

  13. Intra-segment Variations in Geologic Characteristics Along the Eastern Lau Spreading Center and Valu Fa Ridge

    NASA Astrophysics Data System (ADS)

    Sleeper, J. D.; Martinez, F.

    2012-12-01

    Backarc spreading centers located within ~150 km of the arc volcanic front display systematic departures from mid-ocean ridge (MOR) characteristics. The close association of these departures with slab-derived materials in erupted lavas suggests that subduction-related chemical effects are their primary cause. We examine variations in geologic characteristics at the second- and third-order scale along six segments of the arc-proximal Eastern Lau Spreading Center (ELSC) and Valu Fa Ridge (VFR) in the Lau backarc basin, southwest Pacific, using ship multibeam and deep-towed side-scan sonars. Together, the ELSC and VFR constitute a first-order spreading center which progressively approaches the Tofua arc volcanic front southward from ~100-30 km as spreading rates decrease from ~97-39 mm/yr. Second-order segments within VFR (VFR1/VFR2), ~30-50 km from the arc, have axial high morphologies indicative of excess magmatism compared to MOR's spreading at similar rates and erupt increasingly hydrous, vesicular and silicic lavas as the axis approaches the arc. Along-axis topographic highs indicative of locally increased magma supply are located at second-order segment ends, in contrast to the classic MOR model. Along VFR, third-order segments are defined by constructional volcanic ridges, following the classic model of increasing depth toward segment ends, and along VFR2 appear to erupt volcaniclastics at segment centers and lava flows near the ends. Along the southernmost second-order segment of the ELSC (ELSC4), located ~50-60 km from the arc, axial morphology becomes lower relief and much more variable, but still follows the general VFR pattern, where segment ends are shallower and higher relief than the center. Third-order segments form both volcanic ridges that deepen toward the ends, and tectonic grabens that shoal toward the ends, opposite of the MOR model. Beyond ~70 km from the arc, second-order segments become abruptly deeper, erupt less vesicular basaltic lavas, and

  14. A wide-angle seismic survey of the Hecataeus Ridge, south of Cyprus: a microcontinental block from the African plate docked in a subduction zone?

    2013-04-01

    Cyprus lies at the southern edge of the Aegean-Anatolian microplate, caught in the convergence of Africa and Eurasia. Subduction of the African plate below Cyprus has probably ceased and this has been attributed to the docking in the subduction zone of the Eratosthenes Seamount microcontinental fragment on the northern edge of the African plate. In early 2010, on R.V. Maria S. Merian, we conducted a wide-angle seismic survey to test the hypothesis that the Hecataeus Ridge, another possible microcontinental block lying immediately offshore SE Cyprus, might be related to an earlier docking event. The upper crust of southern Cyprus is dominated by ophiolites, with seismic velocities of up to 7 km s-1. A wide angle seismic profile along Hecataeus Ridge was populated with 15 Canadian and German ocean-bottom seismographs at 5 km intervals and these recorded shots from a 6000 cu. in. air gun array, fired approximately every 100 m. Rough topography of the seabed has made picking of phases and their modelling a demanding task. Bandpass and coherency filtering have enabled us to pick phases out to around 80 km. Tomographic inversion of short-range first arrivals provided an initial model of the shallow sub-seabed structure. Forward modelling by ray-tracing, using the code of Zelt and Smith, was then used to model crustal structure down to depths of around 20 km, with occasional evidence of reflections from deeper boundaries (Moho?). Modelling results provide good control on P-wave velocities in the top 20 km and some indications of deeper events. There is no evidence of true velocities approaching 7 km/s in the top 20 km below the Ridge that might indicate the presence of ophiolitic rocks. Regional gravity and magnetic field data tend to support this proposition. We thus conclude that Hecataeus Ridge is not composed of characteristically ophiolitic, Cyprus (upper plate) crust, and it might well be derived from the African (lower) plate.

  15. Influence of riffle characteristics, surficial geology, and natural barriers on the distribution of the channel darter, Percina copelandi, in the Lake Ontario basin

    2005-01-01

    The channel darter, Percina copelandi, is a small benthic fish with a wide but disjunct distribution across central North America. The development of conservation and recovery strategies for Canadian populations is limited by a lack of knowledge regarding ecology, population size and other factors that affect its distribution and abundance. We sampled five rivers in the Lake Ontario basin to test whether the distribution of P. copelandi reflected riffle habitat characteristics or landscape-scale factors such as surficial geology and natural barriers (waterfalls). At most sites yielding P. copelandi, riffles flowed into deep sand bottomed run or pool habitats. Despite a lack of association with local surficial geology or riffle habitat characteristics, both the upstream limits of P. copelandi occurrence and distribution of suitable habitats reflected the distribution of waterfalls, chutes and bedrock outcroppings. In contrast to P. copelandi, distributions of Etheostoma flabellare, P. caprodes and Rhinichthys cataractae reflected among site differences in riffle habitat. ?? Springer 2005.

    More than sixteen years (1997-2013) of continuous ozone concentrations at the rural Agia Marina (EMEP, 532 ma.s.l.) station in Cyprus, together with a number of ancillary chemical and meteorological parameters have been analyzed on a multiannual, annual and diurnal basis. The observations reveal a) the presence of a prominent seasonality with maxima observed during summer (54±5 ppbv) and the minima in winter (39±3 ppbv) b) a relatively small diurnal variability with the noon levels (50±9 ppbv) being higher by ~4 pbbv compared to nighttime (46±9 ppbv) and c) a non-significant upward trend over the 16 years of 0.11±0.12 ppbv y(-1). To assess the spatial variability over Cyprus, simultaneous measurements in 2011-2012 have been performed at Inia, Stavrovouni and Cavo Greco, three remote marine monitoring sites located to the west, central and the east of the Island, respectively. Our results show that ambient ozone levels over Cyprus are mostly influenced by regional/transported ozone while the local precursor emissions play a minor role in ozone formation. On an annual basis a net ozone reduction of 1.5 and 1.0 ppbv occurs when the air masses originate from northerly and westerly directions, respectively, while this is 2.4 ppbv during southerly wind. This suggests continuous net ozone loss controlled by surface deposition and photochemical destruction, and highlights the importance of long-range transport in controlling ozone levels in Cyprus.

    A new map of Moho discontinuity for Levant (Israel, Jordan, Syria, Lebanon and eastern part of the Mediterranean Sea (including Cyprus and Eratosthenes)) has been constructed using integrated analysis of geothermal, seismic, gravity, magnetic, tectonic and some other geophysical and geological data. The developed map indicates that position of Moho in Levant is minimal in the eastern part of Mediterranean Sea (22-26 km), excluding regions of Cyprus (26-36 km) and Eratosthenes (~27 km), and it is maximal for southern Israel 36-40 km) and SW Jordan (38-40 km). On example of Israel and adjoining regions of the Eastern Mediterranean is shown that in the regions with low heat flow and low vertical geothermal gradient the depth of the Curie point could be greater than that of the Moho discontinuity. The new map of Moho discontinuity, along with the improved methods of temperature calculation at depth and geothermal gradients computing, were employed for development of a first Curie point depth map for Israel and adjoining areas. Performed analysis indicates that difference in rocks composition, values of the Curie point for magnetite and titanomagnetite together with the transition between ferric (FeIII) and ferrous (FeII) iron may lead to significant mistakes and ambiguity for the Curie point depth determination in different regions. The obtained results also demonstrate that magnetic data analysis may be used for determination of the bottom edges of magnetized bodies/layers, but for the Curie point depth determination (estimation) it is preferably to apply geothermal methods. Examination of available geophysical data for Levant points at very complex structure of the earth's crust in Cyprus and southern Israel. Some preliminary analysis allowed to suggesting a presence of doubled oceanic crust in Cyprus and fragments of ancient oceanic crust in the upper mantle of southern Israel.

    Radon is a natural gas known to be the main contributor to natural background radiation exposure and second to smoking, a major leading cause of lung cancer. The main source of radon is the soil, but the gas can enter buildings in many different ways and reach high indoor concentrations. Monitoring surveys have been promoted in many countries in order to assess the exposure of people to radon. In this paper, two complementary aspects are investigated. Firstly, we mapped indoor radon concentration in a large and inhomogeneous region using a geostatistical approach which borrows strength from the geologic nature of the soil. Secondly, knowing that geologic and anthropogenic factors, such as building characteristics, can foster the gas to flow into a building or protect against this, we evaluated these effects through a multiple regression model which takes into account the spatial correlation of the data. This allows us to rank different building typologies, identified by architectonic and geological characteristics, according to their proneness to radon. Our results suggest the opportunity to differentiate construction requirements in a large and inhomogeneous area, as the one considered in this paper, according to different places and provide a method to identify those dwellings which should be monitored more carefully.

    The geologic and hydrogeologic characteristics of Tertiary lithostratigraphic units (Ogallala Formation and White River Group) that typically compose or underlie the High Plains aquifer system in southeastern Wyoming were described physically and chemically, and evaluated at a location on the Belvoir Ranch in Laramie County, Wyoming. On the basis of this characterization and evaluation, three Tertiary lithostratigraphic units were identified using physical and chemical characteristics determined during this study and previous studies, and these three units were determined to be correlative with three identified hydrogeologic units composing the groundwater system at the study site—a high-yielding aquifer composed of the entire saturated thickness of the heterogeneous and coarse-grained fluvial sediments assigned to the Ogallala Formation (Ogallala aquifer); an underlying confining unit composed primarily of very fine-grained volcaniclastic sediments and mudrocks assigned to the Brule Formation of the White River Group and some additional underlying sediments that belong to either the Brule or Chadron Formation, or both (Brule confining unit); and an underlying low-yielding aquifer composed primarily of poorly sorted fluvial sediments assigned to the Chadron Formation of the White River Group (Chadron aquifer). Despite widely varying sediment heterogeneity and consolidation, some limited hydraulic connection throughout the full vertical extent of the Ogallala aquifer was indicated but not conclusively proven by interpretation of similar chemical and isotopic characteristics, modern apparent groundwater ages, and similar hydraulic-head responses measured continuously in two Ogallala aquifer monitoring wells installed for this study at two different widely separated (83 feet) depth intervals. Additional work beyond the scope of this study, such as aquifer tests, would be required to conclusively determine hydraulic connection within the Ogallala aquifer. Groundwater

    A new global geologic map of Mars has been completed in a digital, geographic information system (GIS) format using geospatially controlled altimetry and image data sets. The map reconstructs the geologic history of Mars, which includes many new findings collated in the quarter century since the previous, Viking-based global maps were published, as well as other discoveries that were made during the course of the mapping using new data sets. The technical approach enabled consistent and regulated mapping that is appropriate not only for the map's 1:20,000,000 scale but also for its widespread use by diverse audiences. Each geologic unit outcrop includes basic attributes regarding identity, location, area, crater densities, and chronostratigraphic age. In turn, units are grouped by geographic and lithologic types, which provide synoptic global views of material ages and resurfacing character for the Noachian, Hesperian, and Amazonian periods. As a consequence of more precise and better quality topographic and morphologic data and more complete crater-density dating, our statistical comparisons identify significant refinements for how Martian geologic terrains are characterized. Unit groups show trends in mean elevation and slope that relate to geographic occurrence and geologic origin. In comparison with the previous global geologic map series based on Viking data, the new mapping consists of half the number of units due to simpler, more conservative and globally based approaches to discriminating units. In particular, Noachian highland surfaces overall have high percentages of their areas now dated as an epoch older than in the Viking mapping. Minimally eroded (i.e., pristine) impact craters ≥3 km in diameter occur in greater proportion on Hesperian surfaces. This observation contrasts with a deficit of similarly sized craters on heavily cratered and otherwise degraded Noachian terrain as well as on young Amazonian surfaces. We interpret these as reflecting the

    Yucca Mountain, located ~100 mi northwest of Las Vegas, Nevada, has been designated by Congress as a site to be characterized for a potential mined geologic repository for high-level radioactive waste. This field trip will examine the regional geologic and hydrologic setting for Yucca Mountain, as well as specific results of the site characterization program. The first day focuses on the regional setting with emphasis on current and paleo hydrology, which are both of critical concern for predicting future performance of a potential repository. Morning stops will be southern Nevada and afternoon stops will be in Death Valley. The second day will be spent at Yucca Mountain. The field trip will visit the underground testing sites in the "Exploratory Studies Facility" and the "Busted Butte Unsaturated Zone Transport Field Test" plus several surface-based testing sites. Much of the work at the site has concentrated on studies of the unsaturated zone, an element of the hydrologic system that historically has received little attention. Discussions during the second day will compromise selected topics of Yucca Mountain geology, hydrology and geochemistry and will include the probabilistic volcanic hazard analysis and the seismicity and seismic hazard in the Yucca Mountain area. Evening discussions will address modeling of regional groundwater flow, the results of recent hydrologic studies by the Nye County Nuclear Waste Program Office, and the relationship of the geology and hydrology of Yucca Mountain to the performance of a potential repository. Day 3 will examine the geologic framework and hydrology of the Pahute Mesa-Oasis Valley Groundwater Basin and then will continue to Reno via Hawthorne, Nevada and the Walker Lake area.

    The area designated by the city of San Antonio as the Rancho Diana Natural Area is in northern Bexar County, near San Antonio, Texas. During 2008-10, the U.S. Geological Survey, in cooperation with the city of San Antonio, documented the geologic framework and mapped the hydrogeologic characteristics for the southern part of the Rancho Diana Natural Area. The geologic framework of the study area and its hydrogeologic characteristics were documented using field observations and information from previously published reports. Many of the geologic and hydrogeologic features were found by making field observations through the dense vegetation along gridlines spaced approximately 25 feet apart and documenting the features as they were located. Surface geologic features were identified and hydrogeologic features such as caves, sinkholes, and areas of solutionally enlarged porosity were located using hand-held Global Positioning System units. The location data were used to create a map of the hydrogeologic subdivisions and the location of karst features. The outcrops of the Edwards and Trinity aquifer recharge zones were mapped by using hydrogeologic subdivisions modified from previous reports. All rocks exposed within the study area are of sedimentary origin and Lower Cretaceous in age. The valley floor is formed in the cavernous member of the upper Glen Rose Limestone of the Trinity Group. The hills are composed of the basal nodular member, dolomitic member, Kirschberg evaporite member, and grainstone member of the Kainer Formation of the Edwards Group. Field observations made during this study of the exposed formations and members indicate that the formations and members typically are composed of mudstones, wackestones, packstones, grainstones, and argillaceous limestones, along with marls. The upper Glen Rose Limestone is approximately 410 to 450 feet thick but only the upper 70 feet is exposed in the study area. The Kainer Formation is approximately 255 feet thick in

    The importance of the low characteristic velocities of geologic fluids has not been widely recognized, and as a result, the importance of supercritical and supersonic flow in geological processes has generally been underestimated. The lateral blast at Mount St. Helens, Washington, propelled a gas heavily laden with dust into the atmosphere. Because of the low sound speed in this gas (about 100 m/s), the flow was internally supersonic. Old Faithful Geyser, Wyoming, is a converging-diverging nozzle in which liquid water refilling the conduit during the recharge cycle changes during eruption into a two-phase liquid-vapor mixture with a very low sound velocity. The high sound speed of liquid water determines the characteristics of harmonic tremor observed at the geyser during the recharge interval, whereas the low sound speed of the liquid-vapor mixture influences the fluid flow characteristics of the eruption. At the rapids of the Colorado River in the Grand Canyon, Arizona, the channel is constricted into the shape of a converging-diverging nozzle by the debris flows that enter from tributary canyons. Both subcritical and supercritical flow occur within the rapids. -from Author

    LIBS has been proposed as a new method for stand-off detection of geological samples for use on landers and rovers to Mars and studies are on-going to determine capabilities. Because of the severe size, weight, ruggedness and power requirements for space instrumentation and the need to maximize scientific return, it is important to benchmark capabilities with parameters representative of compact instrumentation likely to be used in a flight instrument. Some of these issues are addressed here.

    In this article, the results of the national survey of adult gambling behavior in North Cyprus (NC) in 2012 are presented. The aim of this study is to investigate the characteristics of adults' participation in gambling, and to determine the prevalence of 'problem and pathological gambling' in NC. The population of this study was formed from all the people living permanently in NC, speaking Turkish, and within the age group 18-65. Household interviews were conducted with 966 people. To obtain data, a 30 item questionnaire prepared by the researchers and a Turkish version of the Revised South Oaks Gambling Screen were used. Prevalence rates are compared with the results of the study conducted in 2007 using the same methodology and survey form. The lifetime prevalence of participating at least once in any of the 17 gambling activities investigated in the survey was 66.4 %. 3.5 % of the respondents scored as lifetime probable pathological gamblers and 9.2 % as probable problem gamblers. Risk factors for becoming probable problem and pathological gamblers include being male, being in the 19-28 age group, having a high education level, having a job and being born in Cyprus. This study shows that the prevalence of problem gambling is high in NC and increasing gradually. NC has socio-cultural features such as a history of colonization, socioeconomic problems and high unemployment, similar to other high prevalence gambling regions, which is suggestive of the importance of socio-cultural factors on gambling behavior.

  17. Effect of enhanced x-ray flux on the ionosphere over Cyprus during solar flares

    2015-06-01

    In this work we study the effect of solar flares on the ionosphere over Cyprus. Solar flares are impulsive solar activity events usually coupled with Coronal Mass Ejection (CME). The arrival and the subsequent impact of solar flares on geospace, following an eruption on the Sun's surface is almost immediate (around 9 min) whereas the impact of CMEs is rather delayed (2-3 days) as the former is based on X-ray radiation whereas the latter phenomenon is related with particles and magnetic fields travelling at lower speeds via the Solar Wind. The penetration of X-rays down to the Dregion following such an event enhances the electron density. This increase can be monitored by ionosondes, which measure the electron density up to the maximum electron density NmF2. The significance of this increase lies on the increase of signal absorption causing limited window of operating frequencies for HF communications. In this study the effect of enhanced X-ray flux on the ionosphere over Cyprus during solar flares has been investigated. To establish the correlation and extent of impact on different layers, data of X-ray intensity from Geostationary Operational Environmental Satellite (GOES) and ionospheric characteristics (D & F layer) over Nicosia station (35° N, 33° E) were examined for all solar flares during the period 2011-2014. The analysis revealed a positive and good correlation between frequency of minimum reflection, fmin and X-ray intensity for D layer demonstrating that X-rays play a dominant role in the ionization of lower ionosphere. Hence, X-ray flux can be used as a good proxy for studying the solar flare effects on lower ionosphere. The correlation coefficient between maximum electron density of F layer, NmF2 and X-ray intensity was found to be poor.

    This is the draft topical report on Subtasks 2 and 3 of DOE contract number DE-FG22-89BC14425, entitled ``Establishment of an oil and gas database for increased recovery and characterization of oil and gas carbonate reservoir heterogeneity.`` This volume constitutes the final report on Subtask 3, which had as its primary goal the geological modeling of reservoir heterogeneity in Smackover reservoirs of southwest Alabama. This goal was interpreted to include a thorough analysis of Smackover reservoirs, which was required for an understanding of Smackover reservoir heterogeneity. This report is divided into six sections (including this brief introduction). Section two, entitled ``Geologic setting,`` presents a concise summary of Jurassic paleogeography, structural setting, and stratigraphy in southwest Alabama. This section also includes a brief review of sedimentologic characteristics and stratigraphic framework of the Smackover, and a summary of the diagenetic processes that strongly affected Smackover reservoirs in Alabama. Section three, entitled ``Analytical methods,`` summarizes all nonroutine aspects of the analytical procedures used in this project. The major topics are thin-section description, analysis of commercial porosity and permeability data, capillary-pressure analysis, and field characterization. ``Smackover reservoir characteristics`` are described in section four, which begins with a general summary of the petrographic characteristics of porous and permeable Smackover strata. This is followed by a more-detailed petrophysical description of Smackover reservoirs.

  19. The tectonics of Cyprus Arc: a model of complex continental collision

    Mart, Y.; Ryan, W.

    2003-04-01

    Cyprus Arc is an arcuate depression that wraps the southern reaches of Cyprus in the easternmost Mediterranean Sea. The tectonic regime that constrains Cyprus Arc is generally considered to be that of collision between northward moving Africa and southward moving Eurasia, and the Arc is the site where a Tethyan lithospheric toe off NE Africa is being subducted northward under the Anatolian sub-plate. Evidence to this process is the subduction of Eratosthenes Seamount, located 100 km south of Cyprus, the northern section of which is down-faulted as it subsides toward the Arc. Since Eratosthenes Seamount is rooted in continental lithosphere, and the Troodos ophiolite in southern Cyprus is an oceanic crust, the convergence of Africa and Anatolia along Cyprus Arc was considered a prime example of ongoing obduction. However, abundant GPS evidence shows that Anatolia is moving not southwards but westwards, and the rate of displacement exceeds 20 mm/yr, which is approximately 20 times faster than the rate of the northwards motion of Africa. Earthquakes reflect that composite dynamic model along Cyprus Arc, and compressional, extensional and strike-slip crustal motion co-occur along Cyprus Arc. Seismic reflection profiles show that the structural layout of the eastern segment of Cyprus Arc, from Hecataeus Plateau to Hatay region, is transtensional, emphasizing the prominence of the westwards motion of Anatolia. This composite pattern of the motion of the tectonic plates in the easternmost Mediterranean suggests that the slow northward motion of Africa leads indeed to subduction along Cyprus Arc, but this subduction is not counteracted, because Anatolia is moving much faster westwards. This dynamic setup of plate motion accounts for the composite pattern of earthquake distribution, and is compatible with large lateral displacements along strike of subduction zones and collisional fronts.

  20. Attitudes towards euthanasia in severely ill and dementia patients and cremation in Cyprus: a population-based survey

    2013-01-01

    Background Population studies on end-of-life decisions have not been conducted in Cyprus. Our study aim was to evaluate the beliefs and attitudes of Greek Cypriots towards end-of-life issues regarding euthanasia and cremation. Methods A population-based telephone survey was conducted in Cyprus. One thousand randomly selected individuals from the population of Cyprus age 20 years or older were invited to participate. Beliefs and attitudes on end-of-life decisions were collected using an anonymous and validated questionnaire. Statistical analyses included cross-tabulations, Pearson’s chi-square tests and multivariable-adjusted logistic regression models. Results A total of 308 males and 689 females participated in the survey. About 70% of the respondents did not support euthanasia for people with incurable illness and/or elders with dementia when requested by them and 77% did not support euthanasia for people with incurable illness and/or elders with dementia when requested by relatives. Regarding cremation, 78% were against and only 14% reported being in favor. Further statistical analyses showed that male gender, being single and having reached higher educational level were factors positively associated with support for euthanasia in a statistically significant fashion. On the contrary, the more religiosity expressed by study participants, the less support they reported for euthanasia or cremation. Conclusions The vast majority of Greek Cypriots does not support euthanasia for people with incurable illness and/or elders with dementia and also do not support cremation. Certain demographic characteristics such as age and education have a positive influence towards attitudes for euthanasia and cremation, while religiosity exerts a strong negative influence on the above. Family bonding as well as social and cultural traditions may also play a role although not comprehensively evaluated in the current study. PMID:24060291

    2010-06-01

    Nearly 200 km of high-resolution ground penetrating radar (GPR) data were acquired along the Outer Banks barrier island system of North Carolina, USA. GPR data combined with lithofacies and biofacies data reveal multiple depositional facies including inlet channel, flood-tide delta, overwash, peat and inner shelf. Previously undocumented paleo-inlet channels constitute a significant portion of the shallow geologic framework between Oregon Inlet and Cape Hatteras. GPR data reveal the complex stratigraphy associated with multiple sequences of cut-and-fill within inlet channels. Two types of paleochannels (non-migrating and migrating) were classified based on geometry and fill-patterns. Sediments and foraminifera collected from vibracores were correlated to GPR data to define the regional shallow stratigraphic framework. Channel-fill facies are characterized by clinoform packages, sometimes bounded by erosional surfaces, indicating variable sediment transport directions from the ocean and sound sides. Channels are incised into older flood-tide delta deposits corresponding to older inlet activity when barriers existed further seaward. Flood-tide delta deposits are capped with marsh peat and overwash units. Migrating inlet facies occur under the widest portions of the island, whereas narrow portions of the island are underlain by the non-migrating inlet facies or flood-tide delta/overwash facies. This geologic/geomorphic relationship is attributed to the successional stage of island evolution during transgression, and sediment transport processes associated with the different inlet types. The radar facies, lithofacies, and biofacies provide a comprehensive dataset that will permit more precise identification of barrier island facies in the geologic record.

    A geotechnical and geological investigation of the Farallon Islands low-level radioactive waste (LLW) disposal area was conducted to qualitatively assess the host sediments' relative effectiveness as a barrier to radionuclide migration, to estimate the portion of the barrier that is in contact with the waste packages at the three primary disposal sites, and to provide a basic physical description of the sediments. Box cores recovered from within the general disposal area at depths of 500, 1000, and 1500 m were subcored to provide samples (~30 cm in length) for detailed descriptions, textural and mineralogical analyses, and a suite of geotechnical tests (index property, CRS consolidation, and CIU triaxial compression). -from Authors

    Ports served not only as interfaces between land and sea, but as central gathering spaces for economic and cultural exchange. Drawing on case studies from the eastern Mediterranean island of Cyprus, this paper situates opportunistic ports lacking built facilities within a broader socioeconomic context of diverse maritime communications, expanding rural settlement, and increased agricultural productivity during late antiquity. Though simple, these sites served as active agents in the development of new maritime networks as well as local markets throughout their hinterlands, adding flexibility and dynamism to the economic ties between city, countryside, and the wider late Roman world.

    As Cyprus signed a financial agreement with a team of international lenders, several reform measures were outlined as pre-requisites for disbursement of financial instalments. The health sector was massively reformed in order to enhance efficiency and reduce waste. The magnitude of reforms included introduction of guidelines and clinical algorithms, co-payments, and revision of criteria for public beneficiary status. In order to safeguard equity in access, solidarity in coverage and sustainability of its healthcare sector, reforms must continue unabated and, more importantly, the introduction of a universal health system should be the ultimate goal.

    Users of streamflow information often require streamflow statistics and basin characteristics at various locations along a stream. The USGS periodically calculates and publishes streamflow statistics and basin characteristics for streamflowgaging stations and partial-record stations, but these data commonly are scattered among many reports that may or may not be readily available to the public. The USGS also provides and periodically updates regional analyses of streamflow statistics that include regression equations and other prediction methods for estimating statistics for ungaged and unregulated streams across the State. Use of these regional predictions for a stream can be complex and often requires the user to determine a number of basin characteristics that may require interpretation. Basin characteristics may include drainage area, classifiers for physical properties, climatic characteristics, and other inputs. Obtaining these input values for gaged and ungaged locations traditionally has been time consuming, subjective, and can lead to inconsistent results.

    We conducted a habitat mapping study using integrated seafloor visualization. We obtained precise bathymetry and analyzed seafloor conditions for understanding habitat seafloor characteristics around the nearshore area of Dokdo in the East Sea. The field survey was carried out around the nearshore area of Dongdo(East Islet) and Seodo(West Islet) of Dokdo. We have been acquired the precise topography map using multibeam echosounder systems(EM3001, EM2040(Kongsberg), SONIC2020(R2Sonic)). Seafloor images have been obtained by side scan sonar data(EdegTech 4125) and backscattering data(multibeam echosounder systems). High-resolution underwater video images that represented real seabed environment were obtained by scuba dive survey. Each result of study were applied the integrated visualization techniques. One habitat map shows detailed topography map with geological seabed condition information using bathymetry data and seafloor images. Other habitat map that was fulfilled by detailed bathymetry data and high-resolution underwater video images is helpful to monitoring and comprehend real seafloor environment with topographic condition. The integrated seafloor visualization results present more valuable information than separate geological outputs for seabed environmental mapping study. This study is useful to understand the relations between seafloor characteristics and topographic environments for habitat mapping around the nearshore area of Dokdo.

    A study for a 15-year period (1998-2012) embracing both satellite and rain gauge data is performed over the Mediterranean basin. Tropical Rainfall Measuring Mission (TRMM) 3B43 monthly data (versions 7 and 7A) are compared with the corresponding E-OBS gridded rain gauge precipitation data over a common 0.25 × 0.25° grid. The study focuses over Cyprus, where a dense and reliable network of rain gauges is available. These in situ measurements are compared with both E-OBS and TRMM data for the aforementioned 15-year period. Monthly and (seasonal) yearly comparisons are presented for each of the 0.25 × 0.25° cells overlaying the island of Cyprus. For each of these cells, at least three rain gauges are sited within its corresponding area. BIAS and mean absolute error (MAE) for TRMM and E-OBS estimates from the corresponding averaged gauge data were extracted. The results show a very good correlation (as high as 0.95) over areas where TRMM data incorporate rain gauge measurements along with satellite data. However, the poor correlation over other areas (as low as 0.05) is of great interest and needs to be studied further. The overall conclusion from this study is that TRMM and E-OBS estimates are well fitted with the gauge data, although they are both influenced by the variation of elevation.

  10. Influence of the geologic and geomorphologic characteristics and of crab burrows on the interrelation between surface water and groundwater in an estuarine coastal wetland

    SummaryThe interrelation between surface water and groundwater in intertidal flats is often studied through mathematical models. In many cases these models need to be supported by an integral analysis of the geologic, geomorphologic, hydrologic and biological characteristics of the environment that are to be obtained from field surveys. The marshy environment of the River Ajo in the Samborombon Bay wetland, Argentina, is a typical example of an estuarine coastal zone. Geologic and geomorphologic surveys were carried out, as well as measurements of surface water and groundwater level changes as a response of the aquifer to tidal forcing. The banks of the River Ajo are either scarped with storm flats, or mildly sloped with intertidal flats and numerous crab burrows. Sediments are mainly silty-clayey with low permeability, and lie over silty-sandy layers. At the erosion scarps the tidal wave enters the aquifer as a sub-horizontal flow through the pore space of the sediments. The tidal range in the aquifer depends on the lithological characteristics of the sediments and on the side changes of their hydraulic conductivity. The rise of the water table at high water and its subsequent fall are nearly sinusoidal, with a period similar to that of the tide at the river. At the intertidal flats, instead, the tidal wave enters the aquifer mainly as a sub-vertical flow through the crab burrows. As the crab burrows are not interconnected, they are not distinct pathways for preferential flow. Therefore, the groundwater flux into the river is very slow during low water, and the recovery of the water table takes a long time. The tidal influence upon the water table on both kinds of banks affects only a narrow strip of the aquifer. Not only are the characteristics of the marshy environment of the River Ajo representative of most of the Samborombon Bay wetland; they can also be extended to other similar coastal wetlands to help preserve these invaluable environments.

    The observation and sampling were carried out in May 2013 to April 2014 in a hydrological year for two river basins with different geological background in upstream of Li river basin. The seasonal variations of river water chemistry and its main influencing factors were discussed in this paper. The results showed that the hydrochemistry types of both Darongjiang basin with 9% of carbonates and Lingqu basin with nearly 50% of carbonates in area belonged to Ca-HCO3 type. Ca2+ and HCO3- were the main cations and anions. The main ion concentrations were higher in winter and lower in summer, affected by the change of the flow. Ca2+, Mg2+, HCO3- were mainly sourced from the weathering of carbonates by carbonic acid. The weathering of carbonates by sulfuric acid and the weathering of silicate rocks also had contribution to the river water chemistry. In addition, comparing to the Lingqu basin, the contribution of the weathering of carbonates was much more than the percent of carbonates area, because the carbonate rocks were eroded by the allogenic water. On the other hand, K+, Na+, Cl-, NO3-, SO4(2-) were mainly affected by the atmospheric precipitation and human activities. Comparing to the Darongjiang Basin, the effects of human activities on the changes of K+, Na+, Cl-, NO3-, SO4(2-) were more significant in Lingqu Basin. PMID:27078949

  12. Physical Characteristics, Geologic Setting, and Possible Formation Processes of Spring Deposits on Mars Based on Terrestrial Analogs

    2003-01-01

    Spring formation is a predicted consequence of the interaction of former Martian aquifers with structures common to Mars, including basin margins, Tharsis structures, and other structural deformation characteristics. The arid environment and high abundance of water soluble compounds in the crust will have likewise encouraged spring deposit formation at spring sites. Such spring deposits may be recognized from morphological criteria if the characteristics of formation and preservation are understood. An important first step in the current Mars exploration strategy [10] is the detection of sites where there is evidence for past or present near-surface water on Mars. This study evaluates the large-scale morphology of spring deposits and the physical processes of their formation, growth, and evolution in terms that relate to (1) their identification in image data, (2) their formation, evolution, and preservation in the environment of Mars, and (3) their potential as sites of long-term or late stage shallow groundwater emergence at the surface of Mars.

    Southwest Guizhou Province is one of the most important areas of disseminated, sediment-hosted-type Au deposits in China and is an important area of coal production. The chemistry of most of the coals in SW Guizhou is similar to those in other parts of China. Their As content is near the Chinese coal average, but some local, small coal mines contain high As coals. The highest As content is up to 3.5 wt.% in the coal. The use of high As coals has caused in excess of 3000 cases of As poisoning in several villages. The high As coals are in the Longtan formation, which is an alternating marine facies and terrestrial facies. The coals are distributed on both sides of faults that parallel the regional anticlinal axis. The As content of coal is higher closer to the fault plane. The As content of coal changes greatly in different coal beds and different locations of the same bed. Geological structures such as anticlines, faults and sedimentary strata control the distribution of high As coals. Small Au deposits as well as Sb, Hg, and Th mineralization, are found near the high As coals. Although some As-bearing minerals such as pyrite, arsenopyrite, realgar (?), As-bearing sulfate, As-bearing clays, and phosphate are found in the high As coals, their contents cannot account for the abundance of As in some coals. Analysis of the coal indicates that As mainly exists in the form of As5+ and As3+, perhaps, combined with organic compounds. The occurrence of such exceptionally high As contents in coal and the fact that the As is dominantly organically associated are unique observations. ?? 201 Elsevier Science Ltd.

    Most hydrothermal vents along mid-ocean spreading ridges are high-temperature, sulfide-rich, and low pH (acidic environments). For this reason, the discovery of the Lost City hydrothermal field on the Mid-Atlantic Ridge has stimulated interest in the role of serpentinization of peridotite in generating H2- and CH4-rich fluids and associated carbonate chimneys, as well as in the biological communities adapted to highly reduced, alkaline environments. A new serpentinite-hosted ecosystem, the Shinkai Seep Field (SSF), was discovered by a Shinkai 6500 dive in the inner trench slope of the southern Mariana Trench, near the Challenger Deep, during YK10-12 cruise of R/V Yokosuka in September 2010. Abundant chemosynthetic biological communities, principally consisting of vesicomyid clams are associated with serpentinized peridotite in the SSF. Serpentinization beneath several hydrothermal sites on the Mid-Atlantic Ridge is controlled by interacting seawater and peridotite, variably influenced by magmatic heat. In contrast, the SSF is located in a deep inner trench slope where magmatic heat contribution is unlikely. Instead, serpentinization reactions feeding the SSF may be controlled by persistent fluid flow from the subducting slab. Slab-derived fluid flow is probably controlled by flow through fractures because no serpentinite mud volcano can be discerned along the southern Mariana forearc. Deep-towed IMI-30 sonar backscatter imaging during TN273 cruise of R/V Thomas G. Thompson in January 2012 indicates that the SSF is associated with a small, low backscatter feature that may be a small mound. There are 20 or more of these features in the imaged area, the size of which is ~200 m width and ~200 m to ~700 m long. Since the southern Mariana forearc is heavily faulted, with a deep geology that is dominated by peridotite, more SSF-type seeps are likely to exist along the forearc above the Challenger Deep. The discovery of the SSF suggests that serpentinite-hosted vents may

    Archaean high-Mg granitoids (sanukitoids) occur in the Karelian granite-greenstone terrain in the Baltic Shield in two distinct zones. In the west of the Shield sanukitoid intrusions formed between 2700 and 2720 Ma and consist of a single igneous phase that varies in composition from diorite to granite. In the Eastern part of the Shield, sanukitoid intrusions formed between 2730 and 2745 Ma and are strongly differentiated, varying in composition from ultramafic to felsic. All the sanukitoids are enriched in light rare earth elements (LREE: La≤80 ppm, Ce≤150 ppm, La N/Yb N≤30-40), Sr≤2000 ppm, Ba≤2500 ppm, P 2O 5≤1.5%, alkalis (Na 2O+K 2O=5-10%), possess high mg# values (0.50-0.65), and show a negative Nb-Ta anomaly. They are spatially and temporally related to syenite intrusions and lamprophyre dykes. Sanukitoid intrusions in the Western and Eastern zones differ in composition. In the west, they have higher SiO 2 (mainly>60%) and lower alkalis, Sr, Ba, LREE than in the Eastern zone intrusions. The most differentiated intrusion, the Panozero intrusion in the Eastern zone, was formed in two magmatic cycles separated by ductile deformation. In the first cycle, ultramafic to monzonitic rocks formed, whereas, in the second cycle, the magmas were monzodioritic to quartz monzonite. Ultramafic and mafic rocks make up about 10% of the outcrop and occur as enclaves in monzonites and monzodiorites, and, as dykes, implies a number of discrete magmatic events. All rocks of the Panozero intrusion have high K 2O, and the composition of the initial melt, calculated from the weighted average of the first cycle magmas is monzodiorite (SiO 2=52%, mg#=0.55, Na 2O+K 2O˜6%). The presence of magmatic hornblende and biotite, a high carbonate content, widely distributed explosive breccias and evidence of liquid immiscibility are consistent with a high H 2O-CO 2 content in the sanukitoid melt.

    Mortars with various binding materials have been used across different pre-historic and historic periods to meet several construction applications, such as jointing masonry blocks, finishing walls and isolating water bearing structures. In the framework of an ongoing research programme (NEA ΥΠOΔOMH/NEKΥΠ/0308/17) funded by the Cyprus Research Promotion Foundation, the Republic of Cyprus and the European Union Regional Development Fund, 25 samples of gypsum mortars from different archaeological sites in Cyprus were collected and characterized following a systematic analytical approach. Petrographic observations of thin sections were carried out using polarizing optical microscope. Scanning electron microscopy equipped with energy dispersive X-ray microanalyser (SEM-EDX) was used to examine the microstructure and texture of the mortar samples and to determine semi-quantitatively the chemical composition and interface of their binders. X-ray diffraction (XRD) was performed to identify the main mineral crystalline phases of the specimens' binder and aggregates. Thermal analyses (TG/DTA) were used as a further confirmation of the material composition. The pore structure and volume of the ancient mortars were also determined by mercury intrusion porosimetry (MIP) analysis. Last but not least, a portable drilling resistance measurement system (DRMS) was used for micro-destructive assessment of the mechanical state of the samples. The results confirmed the predominant presence of hydrous calcium sulphate in all samples. Calcite was also found both in the binder and aggregates. Small proportions of SiO2 were also detected. The common ratio of binder to aggregates was 1:2.5. MIP showed porosity values between 14-48% and real densities between 1-1.7 g/cm3. The average pore diameters were smaller in the case of mortars with lower porosity. The use of DRMS indicated lower resistance to drilling for the case of joint mortars (as opposed to analysed gypsum plasters). This

    Shifts in learning goals in introductory earth science courses to greater emphasis on critical thinking and the nature of science has led to the adoption of new pedagogical techniques, including inquiry-based learning (IBL). IBL is thought to support understanding of the nature of science and foster development of scientific reasoning and critical thinking skills by modeling authentic science inquiry. Implementation of new pedagogical techniques do not occur without influence, instruction and learning occurs in a complex learning environment, referring to the social, physical, mental, and pedagogical contexts. This study characterized the impact of an IBL module verses a traditionally structured laboratory exercise in an introductory physical geology class at Texas A&M University. Student activities in this study included manipulation of large-scale data sets, use of multiple representations, and exposure to ill-constrained problems common to the Texas Gulf Coast system. Formative assessment data collected included an initial survey of self efficacy, student demographics, content knowledge and a pre-mental model expression. Summative data collected included a post-test, post-mental model expression, final laboratory report, and a post-survey on student attitudes toward the module. Mental model expressions and final reports were scored according to a validated rubric instrument (Cronbrach alpha: 0.84-0.98). Nine lab sections were randomized into experimental and control groups. Experimental groups were taught using IBL pedagogical techniques, while the control groups were taught using traditional laboratory "workbook" techniques. Preliminary assessment based on rubric scores for pre-tests using Student's t-test (N ˜ 140) indicated that the experimental and control groups were not significantly different (ρ > 0.05), therefore, the learning environment likely impacted student's ability to succeed.

    1996-01-01

    The hydrogeologic subdivisions within the Barton Springs segment of the Edwards aquifer outcrop in northeastern Hays and southwestern Travis Counties generally are porous and permeable. The most porous and permeable appear to be hydrogeologic subdivision VI, the Kirschberg evaporite member of the Kainer Formation; and hydrogeologic subdivision III, the leached and collapsed members, undivided, of the Person Formation. Hydrogeologic subdivision II, the cyclic and marine members, undivided, of the Person Formation, also is quite porous and permeable in Hays County. The porosity of the rocks in the Edwards aquifer outcrop is related to depositional or diagenetic elements along specific stratigraphic horizons (fabric selective) and to dissolution and structural elements that can occur in any lithostratigraphic horizon (not fabric selective). Permeability depends on the physical properties of the rock such as pore size, shape, distribution, fissuring, dissolution, and interconnection of pores and vugs. The Edwards aquifer rocks that crop out in the Barton Springs segment of the Edwards aquifer generally have the same lithologic characteristics as the Edwards aquifer rocks that crop out in Comal and southwestern Hays Counties. However, in the northeastern part of the segment in Travis County, the rock unit that is apparently equivalent to the basal nodular member of the Kainer Formation is called the Walnut Formation. Because the units appear to be stratigraphically and lithologically equivalent, the basal nodular member is used instead of the Walnut Formation for this report. Essentially all of hydrogeologic subdivision II, which is about 70 feet thick in Hays County, is missing in Travis County. In the Barton Springs segment of the Edwards aquifer, the aquifer probably is most vulnerable to surface contamination in the rapidly urbanizing areas on the Edwards aquifer outcrop. Contamination can result from spills or leakage of hazardous materials; or runoff on the

    , changes of physico-chemical conditions resulted in fluid immiscibility that played a key role in gold and sulfide deposition. The geochemical and mineralogical characteristics of the Carlin-type deposits in the western Qinling region are similar to those in the Carlin trend, Nevada, USA. Gold deposits such as La'erma and Jinlongshan occur mostly in the southeastern margin of the western Qinling regionic region whereas some deposits occur in its eastern part. These deposits are hosted in slightly metamorphosed Cambrian to Triassic sedimentary rocks, showing structurally- and stratigraphically-controlled features. The deposits mainly contain submicroscopic and microscopic gold in arsenian pyrite and arsenopyrite, with characteristic ore-forming elements of Au-As-Sb-Ba. The ore-forming fluids are early-stocked formation water and later-recharged meteoric water. Meteoric water apparently evolved in ore-forming fluids by circulation, indicating the extensional setting, and led to the deposition of Au and other elements in cool reactive permeable rocks at shallow levels, forming the disseminated ores. Carlin-like gold deposits occur between the Shang-Dan suture and the Fengxian-Zhen'an fault. The host rocks are mainly sedimentary rocks that underwent reconstruction through reworking by structural metamorphism. These deposits are structurally controlled by brittle-ductile shear zone and occur adjacent to granitoid plutons. The most important characteristic that differ to the orogenic and Carlin-type gold deposits is the genetic relationship with the synchronous magmatism. Gold occurs mainly as microscopic gold. Pyrite and arsenian pyrite can be recognized as gold-bearing minerals. The ore-forming fluids are main magmatic water mixed with metamorphic and/or formation water. Similar to orogenic gold deposits, fluid immiscibility caused the deposition of gold Carlin-like gold deposits.

    The central-western part of Rio Grande do Sul Shield was geologically mapped to test the use of MSS-LANDSAT data in the study of mineralized regions. Visual interpretation of the images a the scale of 1:500,000 consisted, in the identification and analysis of the different tonal and textural patterns in each spectral band. After the structural geologic mapping of the area, using visual interpretation techniques, the statistical data obtained were evaluated, specially data concerning size and direction of fractures. The IMAGE-100 system was used to enlarge and enhance certain imagery. The LANDSAT MSS data offer several advantages over conventional white and black aerial photographs for geological studies. Its multispectral characteristic (band 6 and false color composition of bands 4, 5 and 7 were best suitable for the study). Coverage of a large imaging area of about 35,000 sq km, giving a synoptical view, is very useful for perceiving the regional geological setting.

    The range of 3 degree by 3 degree regional slopes of the Earth and Venus is similar (approximately 0.0-2.4 degrees), although the surface distribution of these values differs significantly. On earth, cratonic and abyssal plains form extensive regions of 0.0 degree slope. Within these regions a variety of features (mid-ocean ridges, volcanic island chains, subduction zones, and floded mountains) have regional slope characteristics influenced by seafloor spreading and plate recycling, as well as an active weathering regime. The plains provinces of Venus are much more rugged than earth's plains and are marked by numerous closely spaced circular and linear features (0.1-0.2 degree regional slope) concentrated into broad linear zones of global extent. Although Venus highlands are bounded by narrow zones of relatively steep slope, the margins of Aphrodite Terra and Beta Regio are not as steep as earth's continental margins and appear to be best developed parallel to the trends of major chasmata within these regions. Ishtar Terra's margins are significantly steeper and more continuous than other highland margins and are comparable to passive margins on earth. The Venus highlands do not contain appreciable smooth, flat interior regions, implying that highland topography is not significantly modified by erosion or deposition.

    The Meadow Creek landslide, part of the Coal Hill landslide complex in western Kane County, Utah, is about 1.7 miles (2.7 km) wide and 1.3 miles (2.1 km) long and contains six smaller historical slides. The upper part of the Meadow Creek landslide is gently sloping and consists of displaced and back-rotated blocks of Cretaceous Dakota and Cedar Mountain Formations that form northeast- to locally east-trending ridges that are separated by sediment-filled half-grabens. The lower part of the landslide is gently to moderately sloping, locally incised, and consists of heterogeneous debris that overrides the Jurassic Carmel Formation near Meadow Creek. Monitoring using a survey-grade Global Positioning System (GPS) instrument detected movement of the southern part of the Meadow Creek landslide between October 2005 and October 2008, including movement of two of the historical slides-landslides 1 and 2. The most movement during the measurement period occurred within the limits of persistently moving landslide 1 and ranged from about 24 to 64 inches (61-163 cm). Movement of the abutting southern part of the Meadow Creek landslide ranged from approximately 6 to 10 inches (15-25 cm). State Route 9 crosses over approximately a mile (1.6 km) of the southern part of the Meadow Creek landslide, including landslide 1. The highway and its predecessor (State Route 15) have been periodically displaced and damaged by persistent movement of landslide 1. Most of the landslide characteristics, particularly its size, probable depth, and the inferred weak strength and low permeability of clay-rich gouge derived from the Dakota and Cedar Mountain Formations, are adverse to and pose significant challenges to landslide stabilization. Secondary hazards include piping-induced sinkholes along scarps and ground cracks, and debris flows and rock falls from the main-scarp escarpment.

  7. Building and Applying "Insularity Theory": Review on Knapp's Prehistoric and Protohistoric Cyprus, 2008.

    NASA Astrophysics Data System (ADS)

    Katsarou-Tzeveleki, Stella

    Prehistoric and Protohistoric Cyprus by A. Bernard Knapp involves us in a highly creative reading. This is due mainly to the fact that the author engages in a holistic synthesis of Cyprus in the Bronze Age, not by emphasizing the events and descriptions of the material remains, but by concentrating upon the difficult question of the identity of the islanders of this period and the processes by which it was formed. The author's teaching of Mediterranean prehistory at the University of Glasgow fully accounts for his need to produce a comprehensive theoretical work of this kind: the basic questions asked by students give rise to theoretical concerns for any teacher aiming to 'distil' the essential synthesis that forms the starting point for any further detailed archaeological description. This essential answer seems to have troubled Knapp for some time, judging by the long list of his writings seeking to synthesize aspects of Cypriot economy, cult and society; the present book is thus the highly interesting outcome of the mature thinking of an experienced fieldworker as much as a theoretical archaeologist and teacher. What, then, is the essential question that Knapp seeks to answer through this book? His question focuses on the identity of the islanders of Cyprus during the 'most formative periods, from the village based culture to the international, town-centred, even state-level polity' (p. 1), the way in which this identity was formed, and how it is reflected in both any recorded event and the material culture of the island in this specific period. Moreover, he also explores more fully what the distinctive features of island identity in general are, how they are constituted and how they influence the material culture of any island population. In seeking the answers, the author avoids a number of the usual approaches to Cypriot archaeology and turns, instead, to new interpretive directions. The approaches he avoids are the citing of events of Cypriot prehistory, the

    Radon (222Rn) is a radioactive gas generated by the decay of the naturally occurring 238U series. It is considered very important from radiological point of view, since it is the most significant natural source of human radiation exposure (approximately 50% from all natural sources). Radon is present in soil, rocks, building materials and waters. Through diffusion and convection, radon migrates and emanates to the atmosphere. Outdoors, radon concentrates at low levels (in the order of 10 Bq/m3). However indoors, radon accumulates significantly. It is trivial to observe indoor environments with high radon levels (in the order of 400 Bq/m3 or higher). Radon accumulation indoors, depends on the composition of the underlying soil and rock formation, on building materials, meteorological parameters, ventilation, heating and water use. Although soil and building materials are the most significant radon sources, there have been reported elevated radon concentrations in building structures due to entering water. It is the radon concentrations in the entering water, the volume and the way of water usage, separated or in combination, that result in large amounts of radon in indoor air. Moreover, radon is a factor of stomach radiation burden due to water consumption. This burden is estimated by measurements of radon concentrations in waters. Due to the health impact of radon exposure, the reporting team continuously measures radon. This work focused on the radon concentrations exposure due to water consumption and use in Greece and Cyprus. Various locations in Greece and Cyprus were accessed taking into consideration existing natural radioactivity data (mainly radon in water), however under the restriction of the capability of movement. Radon in water was measured by Alpha Guard (Genitron Ltd) via a special unit (Aqua Kit). This unit consists of a vessel used for forced degassing of radon diluted in water samples, a security vessel used for water drop deposition. Vessels and

  12. Characteristics of Lunar Lava Ponds as Indicators of Magma Transport Mechanisms and Local-Scale Geology of Ganymede Bright Terrain as Shown by Galileo Very High Resolution Images

    NASA Astrophysics Data System (ADS)

    Yingst, Robin Aileen

    1998-10-01

    The characteristics of 305 small lunar mare deposits (ponds) considered best estimates for individual eruptive phases were analyzed in a global survey. Typical lunar eruptive episodes are relatively smooth and lack features such as large domes and calderas normally associated with shallow magma reservoirs. This suggests deep reservoirs may be prevalent. Mean deposit volume is 370 km3, indicating high volumes per eruption by terrestrial standards. Ponds often are associated with relatively thin crust, suggesting a link between crustal thickness and magma transport. Based upon this estimate of an average lunar flow, potentially ~27,000 separate flows comprise the majority of the contiguous maria, while individual maria may each represent 100s to 1000s of flows. The size of an ideal spherical reservoir associated with an average flow of 370 km3 is estimated to be ~100 km in diameter. These observations and estimates are consistent with a model in which plumes rising diapirically from depth stall at the base of the crust and overpressurize, driving dikes to the surface. Comparison of source region sizes predicted by the model to those using the independently-derived size estimates stated above show that reservoirs of 75-150 km yield overpressure values producing observed volumes. These results are also consistent with the above model. Using very-high resolution images of Xibalba Sulci bright terrain, Ganymede, we have classified three major geological units-craters, massifs and plains-and analyzed their various degradation states in terms of local-scale geological and regolith processes. The lack of many small craters, the distribution of rubble blocks, mantling of hills bases, and the texture of smooth plains all suggest the presence of a fragmental layer, (regolith). Candidates for regolith formation processes include tectonic fragmentation of massifs, downslope movement and impact generation. Evidence for tectonism is observed in N-S trending massifs and lineaments

    Over 40 tick species are naturally infected by Coxiella burnetii. However, little is known about the presence of C. burnetii in other ectoparasites such as fleas. During a 6-year (2000-2006) study, 1147 fleas were collected from 652 animals (252 rats, 118 foxes, and 282 hares) captured from different areas of Cyprus. Three flea species-Xenopsylla cheopis, Ctenocephalides felis, and C. canis-were identified. Fleas were pooled (153 pools) and tested by PCR for the presence of C. burnetii. The pathogen was identified in 25 (16.3%) pools. None of the fleas parasitizing hares was positive for C. burnetii, as opposed to fleas collected from rats (12% pool positivity) and foxes (47.6% pool positivity). The highest prevalence of positive pools was recorded in C. canis (38%) compared to C. felis (16.6%) and X. cheopis (10.8%). All pools of C. canis positive for C. burnetii were removed from foxes (44.4%), whereas all positive X. cheopis (10.8%) were removed from rats. The role of fleas in the maintenance and transmission of C. burnetii among wild vertebrates remains to be determined. PMID:25198524

    This paper details the experiences of the Princess Mary's Royal Air Force Hospital, Akrotiri (TPMH), during the last 6 months of 1974. TPMH was at that time a small hospital (120 beds) with a clinical staff of 17 situated in the south of Cyprus (fig. 1). The series comprises 71 patients injured by bullets, shrapnel, bomb-blasts or mines, drawn from British personnel, United Nations Forces and the local Cypriot military and civilian population, resulting from the coup d'état of 15 July 1974 and the subsequent Turkish invasion and air attacks. The casualties were often severely wounded beyound the capabilities of the local hospitals. They were mostly admitted during a 2-week period, but many required multiple operations extending over the next 3 or 4 months, and altogether 119 operations were carried out on 41 patients at TPMH. The organization of the limited resources of the medical, nursing and supporting staff is outlined. The correct treatment of missile wounds is emphasized. Resuscitation, wound excision, splintage and delayed suture or grafting are essential. Minimal morbidity and mortality are gained by a practised approach to the compounded results of violence.

    The recent history of Cyprus presents an example of a society in which a centuries-long peaceful coexistence of diverse populations gave way to violence and murderous hate, with devastating end results. This paper tries to understand and describe the process by which Cypriot society slid from a position of psychosocial equilibrium and integration towards one of disintegration, fragmentation and catastrophic breakdown. This paper draws from work by social anthropologists, sociologists, historians and others, and from my own personal experience. To these I applied insights afforded by psychoanalysis to identify and explore the psychic processes and states of mind that characterized a psychosocial disintegrative process. I came to see external political events and internal psychological processes as inseparably intertwined and dynamically interdependent, each emanating from and catalysing the other. The factual details of the process described are of course unique in their local specificity, but the psychic phenomena that characterized it are not: at both the individual and group levels they are replicated in other societies undergoing similar processes of self-destruction.

    In this paper we present data from a cross-sectional study on cyberbullying experiences and cyberbullying perpetration in the Republic of Cyprus. Data were collected from a representative sample of the adolescent student population of the first and fourth grades of high school. Total sample was 2684 students, 48.5% of them male and 51.5% female. Research material included extended demographics, a detailed questionnaire on Internet activities, the Parental Bonding Index (PBI) and the Strengths and Difficulties Questionnaire (SDQ). We compared the results on psychometry for those students who did not report being bullied or having bullied others with those who were bullied, those who bullied others and those who were both sufferers and perpetrators of cyberbullying. Those students who reported being both victims and perpetrators tended to show similar or higher dysfunction than those students who only perpetrated cyberbullying. High maternal and paternal protection in combination with low maternal and paternal care ('affectionless control' parenting style) was associated with perpetrating cyberbullying, either with or without any experience of oneself being bullied as well. Results support a hypothesis that the perpetration of cyberbullying is associated with inefficient parenting styles. They also point to the existence of significant emotional symptoms for the involved adolescents and also general conduct problems, hyperactivity, peer problems and antisocial tendencies. It is important to note that perpetrators of cyberbullying were in most cases victims themselves at some point in time. PMID:23792849

    This paper presents results from the study of gambling behaviors in a representative sample of Cypriot high-school students. The aim of the study was to ascertain epidemiology of adolescent online gambling in Cyprus and possible correlates. The sample consisted of 2,684 students (48.5% boys, 51.5% girls) from the first grades of junior (Gymnasium) and senior (Lyceum) high school. Our results indicate that gamblers presented with lower school achievement and related expectations while scoring consistently higher on measures of Internet addiction, parental bonding and psychopathology. Discriminant analysis revealed two profiles which explained the most variance in gambling behavior; the first profile that corresponded to more explained variance was the student with higher psychopathology, less prosocial behavior, higher Internet addiction score with higher frequencies of online activities and moderate levels of truancy and lower expectation of school achievement. The second profile was that of a student who reported less psychopathology, more prosocial behavior, less involvement with the Internet in general but skipped classes more and his prospects on finishing high school were even slimmer. These results will be utilized in the design of a comprehensive prevention program in an effort to combat online addictive behaviors. PMID:24293015

    2003-01-01

    Aviation deregulation is usually a challenging and demanding task and accession to the European Union requires that all candidate states should harmonize their legislation in the context of the European Common Aviation Area. Malta and Cyprus, the small Mediterranean island-states to join the EU in 2004, will have to abandon any protectionist policies in favour of their flag-carriers and let them survive in a liberal framework. The paper discusses the implications of this regime change for civil aviation in Malta and Cyprus and in addition to the airline industry, it examines the impacts on the complementary tourism sector. Unless carrying capacity limits are understood, the islands may become victims of successful airline liberalisation. The paper concludes by stressing the need for sustainable development and active policy making. Keywords: carrying capacity, Cyprus, air transport deregulation, Malta, tourism

    Water allocation to crops has always been of great importance in agricultural process. In this context, and under the current conditions, where Cyprus is facing a severe drought the last five years, purpose of this study is basically to estimate the needed crop water requirements for supporting irrigation management and monitoring irrigation on a systematic basis for Cyprus using remote sensing techniques. The use of satellite images supported by ground measurements has provided quite accurate results. Intended purpose of this paper is to estimate the Evapotranspiration (ET) of specific crops which is the basis for irrigation scheduling and establish a procedure for monitoring and managing irrigation water over Cyprus, using remotely sensed data from Landsat TM/ ETM+ and a sound methodology used worldwide, the Surface Energy Balance Algorithm for Land (SEBAL). The methodology set in this paper refers to COST action ES1106 (Agri-Wat) for determining crop water requirements as part of the water footprint and virtual water-trade.

    Aerosols can have a complicated influence on climate conditions, directly as well as indirectly via cloud formation. The southeastern Mediterranean region can be characterized as a cross road of aerosols originating from European, Asian and African continents. Complex vertical aerosol distributions are frequently detected over Cyprus by means of active remote sensing. Observations of such complex aerosol layering and comparison of the measurements with aerosol products of regional and global atmospheric transport models are required to improve our understanding of life cycles of aerosol mixtures and their impact on climate as well as on satellite remote sensing products. In this study, a case of an intense desert dust outbreak from Syria and Saudi Arabia towards the eastern Mediterranean in September 2011 is presented. The observations used in this study were performed with a 532-nm polarization Lidar and a sun/sky AERONET photometer operated at 8 channels from 340 to 1640 nm wavelength. Both instruments belong to remote sensing station of the Cyprus Technical University at Limassol, Cyprus (34°N, 33°E). The lofted dust plume was doped with air masses that crossed sources of biomass burning smoke and anthropogenic pollution. In addition, the shallow marine boundary layer over the Mediterranean Sea and over Limassol became mixed with the anthropogenic haze by sea breeze circulations. The case study demonstrates the potential of combined lidar/photometer observations to deliver detailed vertically resolved information of the aerosol characteristics in terms of particle optical and microphysical properties, separately for the spherical particle fraction as well as for the non-spherical aerosol mode.

    Hiromeri is a specialty ham of Cyprus, made of smoked pork leg that is matured in wine. Until now there has been no systematic effort to present historical evidence that will support the Cypriot authenticity of this product. In this article, the historical evidence from sixteenth to twentieth centuries, referring to the production and trade of hiromeri in Cyprus, is presented. The evidence is drawn from archival testimony, travelers' descriptions, old history books, and essays on agricultural production. Moreover, a description of the hiromeri production process as well as past and current culinary uses and customs associated with its production and consumption are presented. PMID:23621488

    The Çaldıran Fault is a strike slip fault with a dextral slip in East Anatolia. The activity on this fault was marked by the November, 24 1976 earthquake (Mw: 7.1) which produced an ~ 50 km long surface rupture and caused 3840 fatalities, which was close to half of the population living along the fault at that time. Together with the North Tabriz Fault in Iran, it is regarded as the southern boundary of the Caucasus Block. The fault has an average annual slip rate of 8.1 from 10.8 mm yr- 1, as derived from elastic block modelling. We present results from a detailed morphotectonic survey along the fault. The Çaldıran Fault is comprised of three segments, each of which is eparated by bend structures that bend towards the SW with a total change in strike of 20° from east to west. The offsets of lithological contact markers show that the long-term geological slip rate for the Çaldıran fault is approximately 3.27 ± 0.17 mm yr- 1for a duration of approximately 290 ka. The cumulative offset of the fault was determined from an analysis of a dome-shaped rhyolitic volcano which constrained the age of the fault to the Middle-Late Pleistocene. An analysis of small-scale morphological offset markers indicates a characteristic slip behaviour of the Çaldıran Fault for the last 3 events with an average offset of 2.6 m.

    A detailed structural analysis of the Mesozoic-Cenozoic geological development of the central segment of the Kyrenia Range in its regional tectonic context is given here. The structural evidence comes from five structural traverses, outcrop observations, small-scale structures and related regional evidence. The majority of the structures are fault planes, of which a subordinate number exhibit slickenlines (fault plane data, n = 2688; with kinematics, n = 537). Additional kinematic data were obtained from C-S fabrics and folds. Small-scale structures in each stratigraphic unit were `backstripped' to reveal relative chronology. Synthesis of the structural information indicates three phases of convergence-related deformation: (1) Late Cretaceous, associated with greenschist facies metamorphism, followed by exhumation that was probably associated with WNW-ESE to ENE-WSW-trending high-angle faulting; (2) Mid-Eocene, associated with southward thrusting, coupled with ~N-S strike-slip (transfer faulting) and oblique faulting in an overall sinistral transpressive stress regime; (3) Late Miocene-earliest Pliocene, involving southward thrusting and folding, localised back-thrusting, extensive fault reactivation and large-scale segmentation of the range. Intense uplift of the Kyrenia Range took place during the Plio-Pleistocene, possibly related to the collision of the Eratosthenes Seamount with the Cyprus trench to the south of the island. The three main convergent phases relate to stages of northward subduction and diachronous continental collision affecting the northerly, active continental margin of the Southern Neotethys.

    "While we teach, we learn" (Roman philosopher Seneca) One of the most beneficial ways to remember a theory or concept is to explain it to someone else. The offer of fieldwork and visits to exciting destinations is arguably the easiest way to spark a students' interest in any subject. Geology at A-Level (age 16-18) in the United Kingdom incorporates significant elements of field studies into the curriculum with many students choosing the subject on this basis and it being a key factor in consolidating student knowledge and understanding. Geology maintains a healthy annual enrollment with interest in the subject increasing in recent years. However, it is important for educators not to loose sight of the importance of recruitment and retention of students. Recent flexibility in the subject content of the UK curriculum in secondary schools has provided an opportunity to teach the basic principles of the subject to our younger students and fieldwork provides a valuable opportunity to engage with these students in the promotion of the subject. Promotion of the subject is typically devolved to senior students at Hessle High School and Sixth Form College, drawing on their personal experiences to engage younger students. Prospective students are excited to learn from a guest speaker, so why not use our most senior students to engage and promote the subject rather than their normal subject teacher? A-Level geology students embarking on fieldwork abroad, understand their additional responsibility to promote the subject and share their understanding of the field visit. They will typically produce a series of lessons and activities for younger students using their newly acquired knowledge. Senior students also present to whole year groups in seminars, sharing knowledge of the location's geology and raising awareness of the exciting destinations offered by geology. Geology fieldwork is always planned, organised and led by the member of staff to keep costs low, with recent visits

    Extreme temperatures have long been associated with adverse health impacts, ranging from minor illness, to increased hospitalizations and mortality. Heat-related mortality during summer months is likely to become an increasing public health problem in future due to the effects of climate change. We performed a health impact assessment for heat-related mortality for the warm months of April-September for the years 2004 to 2009 inclusive, for the city of Nicosia and for Cyprus as a whole, based on separately derived exposure-response functions. We further estimated the potential future heat-related mortality by including climate projections for southern Europe, which suggest changes in temperature of between 1°C and 5°C over the next century. There were 32 heat-related deaths per year in Cyprus over the study period. When adding the projected increase in temperature due to climate change, there was a substantial increase in mortality: for a 1°C increase in temperature, heat related mortality in Cyprus was estimated to double to 64 per year, and for a 5°C increase, heat-related mortality was expected to be 8 times the baseline rate for the warm season (281 compared with 32). This analysis highlights the importance of preparing for potential health impacts due to heat in Cyprus, particularly under a changing climate. PMID:27376918

    Hospital procurement is a crucial field for any health care system, not only for economic reasons but also for reasons related to the quality and safety of the services provided. That is why the process of procurement is, in most countries, governed by a strict legal framework and policy mechanisms. This study investigates the problems and inefficiencies associated with the procurement of medical devices in public hospitals in Cyprus and formulates empirically documented proposals for improvement. Using the Delphi method, a group of 38 experts approach the procurement system in Cyprus from different angles, achieving high rates of consensus on 35 different statements on the weaknesses and problems of the current medical device procurement system, as well as presenting proposals and recommendations for improvement. The findings are highly valuable for future policy initiatives in Cyprus in the light of the economic crisis and the expected implementation of the new General Health Insurance System (GeSY), which the Government of the Republic of Cyprus and the Troika has agreed.

    An ethnobotanical survey of wild edible plants of Cyprus was carried out in two sites. Paphos vine zone and Larnaca mixed farming zone. These are among the areas in Cyprus whose inhabitants subsisted primarily on pastoralism and agriculture and therefore still preserve the traditional knowledge on wild edible plants. The information was collected for three-year period, in the framework of the EU-funded RUBIA Project. Four hundred and thirteen interviews have been administered to 89 informants of various ages and background categories in 29 villages of Paphos site, and 8 in Larnaca site. A total of 78 species were recorded. Ethnographic data related to vernacular names, traditional tools and recipes have also been recorded. A comparison of the data collected from the two sites is undertaken. During this ethnobotanical research it was verified that wild edibles play an important role in Cyprus in rural people, however, it was realized that the transmission of folk uses of plants decreased in the last generations. The research of ethnobotany should be extended to other areas of Cyprus in order not only to preserve the traditional knowledge related to plants but to make it available to future generations as well.

    2015-03-01

    Here we use bulk and amino acid-specific stable nitrogen (N) isotope analysis (AA-CSIA) to evaluate seasonal and regional change in mesozooplankton dynamics for the first time in coastal waters of the eastern Mediterranean. Cyprus mesozooplankton δ15N values were significantly higher in late winter (2.3‰) than in summer (1.2‰), and in all cases were less than the δ15N values of mesozooplankton in the northeast Aegean Sea (NEA; 3.4‰). AA-CSIA indicates that these differences can primarily be attributed to seasonal and regional change in mesozooplankton community trophic structure, with overall trophic position increasing by 0.2-0.3 in winter as compared to summer around Cyprus, and trophic position higher in the NEA than in Cyprus by 0.3-0.6. Such differences are most likely related to the larger contribution of carnivorous mesozooplankton observed in winter around Cyprus and in the NEA. Overall, our findings indicate change in bulk mesozooplankton δ15N value in the eastern Mediterranean is primarily driven by change in community trophic position, rather than variability in δ15N value at the base of the food web.

    Theodorou, Mamas; Georgiou, Marina; Nikolentzos, Athanasios; Bellali, Thalia

    2015-01-01

    Hospital procurement is a crucial field for any health care system, not only for economic reasons but also for reasons related to the quality and safety of the services provided. That is why the process of procurement is, in most countries, governed by a strict legal framework and policy mechanisms. This study investigates the problems and inefficiencies associated with the procurement of medical devices in public hospitals in Cyprus and formulates empirically documented proposals for improvement. Using the Delphi method, a group of 38 experts approach the procurement system in Cyprus from different angles, achieving high rates of consensus on 35 different statements on the weaknesses and problems of the current medical device procurement system, as well as presenting proposals and recommendations for improvement. The findings are highly valuable for future policy initiatives in Cyprus in the light of the economic crisis and the expected implementation of the new General Health Insurance System (GeSY), which the Government of the Republic of Cyprus and the Troika has agreed.

    Weber, John; Frankel, Kurt L.

    2011-05-01

    Structural geology and continental tectonics were ushered in to the modern quantitative age of geosciences with the arrival of the global plate tectonics paradigm (circa 1968), derived using new data from the oceans' depths, and John Ramsay's 1967 seminal work, Folding and Fracturing of Rocks. Fossen is to be applauded for crafting a unique, high-caliber, and accessible undergraduate textbook on structural geology that faithfully reflects this advance and the subsequent evolution of the discipline. This well-written text draws on Fossen's wealth of professional experience, including his broad and diverse academic research and experience in the petroleum industry. This book is beautifully illustrated, with excellent original color diagrams and with impressive color field photographs that are all keyed to locations and placed into geologic context.

    1986-07-01

    The Society of Economic Paleontologists and Mineralogists, in collaboration with the International Association of Sedimentologists and the International Union of Geological Sciences Committee on Sedimentology, is developing a new international study under the provisional title of Global Sedimentary Geology Program (GSGP). Initially, three research themes are being considered: (1) event stratigraphy-the documentation of examples of mass extinctions, eustatic fluctuations in sea level, major episodes of volcanisms, and changes in ocean composition; (2) facies models in time and space-an expansion of the existing data base of examples of facies models (e.G., deltas, fluvial deposits, and submarine fans) and global-scale study of the persistence of facies at various times in geologic history; and (3) sedimentary indices of paleogeography and tectonics-the use of depositional facies and faunas in paleogeography and in assessing the timing, locus, and characteristics of tectonism. Plans are being developed to organize pilot projects in each of these themes.

  18. Theoretical geology

    Mikeš, Daniel

    2010-05-01

    Theoretical geology Present day geology is mostly empirical of nature. I claim that geology is by nature complex and that the empirical approach is bound to fail. Let's consider the input to be the set of ambient conditions and the output to be the sedimentary rock record. I claim that the output can only be deduced from the input if the relation from input to output be known. The fundamental question is therefore the following: Can one predict the output from the input or can one predict the behaviour of a sedimentary system? If one can, than the empirical/deductive method has changes, if one can't than that method is bound to fail. The fundamental problem to solve is therefore the following: How to predict the behaviour of a sedimentary system? It is interesting to observe that this question is never asked and many a study is conducted by the empirical/deductive method; it seems that the empirical method has been accepted as being appropriate without question. It is, however, easy to argument that a sedimentary system is by nature complex and that several input parameters vary at the same time and that they can create similar output in the rock record. It follows trivially from these first principles that in such a case the deductive solution cannot be unique. At the same time several geological methods depart precisely from the assumption, that one particular variable is the dictator/driver and that the others are constant, even though the data do not support such an assumption. The method of "sequence stratigraphy" is a typical example of such a dogma. It can be easily argued that all the interpretation resulting from a method that is built on uncertain or wrong assumptions is erroneous. Still, this method has survived for many years, nonwithstanding all the critics it has received. This is just one example of the present day geological world and is not unique. Even the alternative methods criticising sequence stratigraphy actually depart from the same

    The Eratosthenes Seamount is the most striking bathymetric feature situated in the midst of the eastern Mediterranean seafloor about 100 km south of Cyprus. The tabular top is about 120 by 80 km wide lying at a depth of 700 m and rising more than 1000 m above the adjacent seafloor. This Seamount comprises of a continental fragment of the African Plate. The seamount started to collide with the Cypriot Arc during the early Pleistocene, which triggered a series of synchronous deformations across the collision zone between the African-Sinai-Arabia and Eurasia-Anatolia plates, including the entire eastern Mediterranean region. New bathymetry data acquired in spring 2010 shed light on cascading geo-hazards resulting from the incipient continent-continent collision.The slopes of the Eratosthenes Seamount are characterized by numerous slumps or debris flows of various generations and canyons, indicating mass wasting processes at its flanks. At the eastern side e.g. one slump complex is around 15 km long and 3.5 km wide in its middle part. Here, the canyons are intersected by graben related faults, which proves that the canyons evolved prior to the early Pliocene collision. The seamount is surrounded by a 5-20 km wide trench. Meandering channels with a high sinuosity incised into the flat seafloor of this trench and the wavy adjacent seafloor. The longest meandering channel can be traced over more than 120 km in the study area. Width of this channel is around 800 m with a depth of 25-40 m. With the exception of the western study area the outer edge of the trench is marked by a 200-600 m high escarpment. The surrounding seafloor of the Levantine and Herodotus Basins exhibits elongated folds which correspond to the surface of the underlying Messinian evaporites. The folding results from thin-skinned compression due to lateral salt creeping. Meandering channels cut through the elongated folds, thus indicating a recent formation. Parametric subbottom profiler data reveal mainly

    2007-01-01

    Objectives This study investigated concerns that have been raised about past and future health effects caused by high power transmissions of high frequency (7–30 MHz) radio waves from military antenna systems at Akrotiri, Cyprus. Methods A cross‐sectional study of three villages (two exposed, one unexposed) collected longitudinal and short‐term radiofrequency measurements. Health data were collected using questionnaires containing information on demographic factors, specific illnesses, general health (SF‐36 well‐being questionnaire), reproductive history, childhood illnesses, risk perception and mortality. Analysis was with SPSS v11.5 using cross tabulations of non‐parametric data and tests for significance. Key health outcomes were subjected to logistic regression analysis. Results Field strengths within the two “exposed” villages were a maximum of 0.30 (Volts/Vm−1 metre) from the 17.6 MHz military transmissions and up to 1.4 Vm−1 from unspecified sources, mainly cell phone frequencies. The corresponding readings in the control village were <0.01 Vm−1. Compared with the control village there were highly significant differences in the reporting of migraine (OR 2.7, p<0.001), headache (OR 3.7, p<0.001), and dizziness (OR 2.7, p<0.001). Residents of the exposed villages showed greater negative views of their health in all eight domains of the SF‐36. There were also higher levels of perceived risk, particularly to noise and electromagnetic “pollution”. All three villages reported higher values of risk perception than a UK population. There was no evidence of birth abnormalities or differences in gynaecological or obstetric history. Numbers of cancers were too small to show differences. Conclusion It was clear that even this close (1–3 km) to powerful transmissions, the dominant sources of radiofrequency fields were cell phone and national broadcast systems. There was no excess of cancer, birth defects or obstetric problems

  4. Sedimentary development and correlation of Late Quaternary terraces in the Kyrenia Range, northern Cyprus, using a combination of sedimentology and optical luminescence data

    2016-01-01

    This study focuses on the younger of a series of Quaternary terraces along the flanks of the Kyrenia Range in northern Cyprus, specifically the Kyrenia (Girne) and the Koupia terraces. The Kyrenia (Girne) terrace is tentatively correlated with oxygen isotope stage 5 (125 Ka), and the Koupia terrace with oxygen isotope stage 3 (<50 Ka). Along the northern flank of the range, the Kyrenia (Girne) terrace deposits (5-20 m above modern sea level) typically begin with a basal lag conglomerate and then pass upwards into shallow-marine calcarenites and then into variable aeolianites, paleosols and fluvial deposits (up to 20 m thick). In contrast, the Koupia terrace (<2 m above modern sea level) consists of aeolianites and shallow-marine calcarenites (up to 8 m thick). The equivalent deposits along the southern flank of the range are entirely non-marine fluvial mud, sands and conglomerates. The marine to continental terrace systems can be tentatively correlated based on mapping, height above modern sea level and sedimentary facies. However, variable preservation and patchy exposure require such correlations to be independently tested. To achieve this, a portable optically stimulated luminescence (OSL) reader was used to determine the luminescence characteristics of the two terrace systems. Luminescence profiles show major differences in luminescence characteristics between the two terrace depositional systems, which can be related to sedimentary processes, provenance and age. These features allow sections in different areas to be effectively correlated. Individual sections show luminescence properties that are generally consistent with an expected up-sequence decrease in age. However, the younger Koupia terrace deposits show higher luminescence intensities compared with the older Kyrenia (Girne) terrace deposits. This can be explained by multiple phases of reworking of the Kyrenia (Girne) terrace deposits, which changed the luminescence characteristics of the sediment. The

    Long term monitoring of PM concentrations in Cyprus reported the occurrence of a significant number of PM exceedances above the limits set by EU legislation and point out the need for abatement strategies. To address these critical issues, mass and chemical composition of daily PM10 aerosol samples were collected at a suburban (Limassol; LIM RES), a natural background site (EMEP site, Ayia Marina) and an urban center (Nicosia, NIC TRA) from January 2010 to December 2010. By considering the chemical composition measured at EMEP as representative of the regional background, the contribution of local sources at both NIC TRA and LIM RES sites can be also estimated. In total, "local" ions account for 1.7 and 2.4 μg m-3, i.e 33 and 48% of the total ionic mass recorded in NIC TRA and LIM RES. Sea salt attained levels of 2.3 ± 1.2 μg m-3, 1.9 ± 1.3 μg m-3 and 3.5 ± 2.3 μg m-3, contributing up to 10, 7 and 11% of the PM10 mass measured at EMEP, NIC TRA and LIM RES, respectively. The local concentrations of OC and EC were equal to 3.3±1.1 μg m-3 and 3.2±1.3 μg m-3 for NIC TRA and 1.70±0.03 μg m-3 and 1.39±0.42 μg m-3 for LIM RES relative to the values measured at the EMEP site. The high EC concentrations in NIC TRA underline the major role of traffic-related emissions. As expected for the natural background site, OC/EC ratio equals 4.84, a strong indicator of secondary organic aerosol (SOA) formation. Whereas in the urban and suburban sites, the OC/EC ratio is lower ranging from 1.46 to 1.84, denoting significant influence from fossil fuel primary emissions in the studied areas. Considering that dust at EMEP is due to "regional" dust, the dust measured at both traffic related sites is the sum of "regional" and "local dust", the second most probably originating from soil dust and car/road abrasion. The "local dust" at NIC TRA and LIM RES accounted for 28% and 21% of the total PM10 mass, whilst regional dust at EMEP of 45%. The temporal variation of "local dust

    Kokanee salmon (Oncorhynchus nerka) are a keystone species in Lake Pend Oreille in northern Idaho, historically supporting a high-yield recreational fishery and serving as the primary prey for the threatened native bull trout (Salvelinus confluentus) and the Gerrard-strain rainbow trout (Oncorhynchus mykiss). After 1965, the kokanee population rapidly declined and has remained at a low level of abundance. Lake Pend Oreille is one of the deepest lakes in the United States, the largest lake in Idaho, and home to the U.S. Navy Acoustic Research Detachment Base. The U.S. Geological Survey and Idaho Department of Fish and Game are mapping the bathymetry, morphology, and the lakebed geologic units and embeddedness of potential kokanee salmon spawning habitat in Lake Pend Oreille. Relations between lake morphology, lakebed geologic units, and substrate embeddedness are characterized for the shore zone, rise zone, and open water in bays and the main stem of the lake. This detailed knowledge of physical habitat along the shoreline of Lake Pend Oreille is necessary to better evaluate and develop kokanee recovery actions.

  7. A feasibility study for the provision of electronic healthcare tools and services in areas of Greece, Cyprus and Italy

    Background Through this paper, we present the initial steps for the creation of an integrated platform for the provision of a series of eHealth tools and services to both citizens and travelers in isolated areas of thesoutheast Mediterranean, and on board ships travelling across it. The platform was created through an INTERREG IIIB ARCHIMED project called INTERMED. Methods The support of primary healthcare, home care and the continuous education of physicians are the three major issues that the proposed platform is trying to facilitate. The proposed system is based on state-of-the-art telemedicine systems and is able to provide the following healthcare services: i) Telecollaboration and teleconsultation services between remotely located healthcare providers, ii) telemedicine services in emergencies, iii) home telecare services for "at risk" citizens such as the elderly and patients with chronic diseases, and iv) eLearning services for the continuous training through seminars of both healthcare personnel (physicians, nurses etc) and persons supporting "at risk" citizens. These systems support data transmission over simple phone lines, internet connections, integrated services digital network/digital subscriber lines, satellite links, mobile networks (GPRS/3G), and wireless local area networks. The data corresponds, among others, to voice, vital biosignals, still medical images, video, and data used by eLearning applications. The proposed platform comprises several systems, each supporting different services. These were integrated using a common data storage and exchange scheme in order to achieve system interoperability in terms of software, language and national characteristics. Results The platform has been installed and evaluated in different rural and urban sites in Greece, Cyprus and Italy. The evaluation was mainly related to technical issues and user satisfaction. The selected sites are, among others, rural health centers, ambulances, homes of "at

    The Geological Surveys of the European countries hold valuable resources of geological data but, to discover, understand and use this data efficiently, a good level of standardization is essential. The OneGeology-Europe project had the aim of making geological maps at a scale 1:1M from Europe discoverable and accessible, available under a common data license and described by multilingual metainformation. A harmonized specification for basic geological map data was developed so that significant progress towards harmonizing the datasets was achieved. Responsibility for the management of the OneGeology-Europe portal has been taken by EuroGeoSurveys and provided by CGS and BRGM. Of the 34 members of EuroGeoSurveys (EGS), only 20 participated in the OneGeology-Europe project (Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Ireland, Italy, Luxembourg, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Sweden, Spain, United Kingdom), so the European area was not completely covered. At the 33rd General Meeting and Directors Workshop in 2012 it was therefore decided to establish a successor initiative OneGeology Europe Plus (1G-E+) with the purpose of extending the coverage by geological maps at a scale of 1:1 M to all the EGS member countries (including Albania, Austria, Bulgaria, Croatia, Cyprus, Greece, Iceland, Lithuania, Malta, Romania, Russia, Switzerland, Turkey, Ukraine) and also, if possible, to the other European countries (Belorussia, Bosnia and Herzegovina, Faeroe Islands, Kosovo, Latvia, Macedonia, Moldavia, Montenegro, Serbia). In order to achieve the desired result, it has been necessary for the new GSOs who intend to supply the additional 1G-E standardized services to carry out the work using their own staff and resources. The technical guidance and other support have been provided by the 1G-E+ Technical Support Team, funded from the internal budgets of their respective surveys. The team is coordinated by the Czech

    In many regions of the world, climatic change is associated with increased extreme temperatures, which can have severe effects on mortality and morbidity. In this study, we examine the effect of extreme weather on hospital admissions in Cyprus, for inland and coastal areas, through the use of synoptic weather classifications (air mass types). In addition, the effect of particulate air pollution (PM10) on morbidity is examined. Our results show that two air mass types, namely (a) warm, rainy days with increased levels of water vapour in the atmosphere and (b) cold, cloudy days with increased levels of precipitation, were associated with increased morbidity in the form of hospital admissions. This was true both for cardiovascular and respiratory conditions, for all age groups, but particularly for the elderly, aged over 65. Particulate air pollution was also associated with increased morbidity in Cyprus, where the effect was more pronounced for cardiovascular diseases. PMID:26519584

    Water resources in Cyprus are scarce and expensive to exploit; rainfall is highly variable and droughts occur frequently. The Cyprus authorities are concerned with the conservation and protection of water supply sources. For this purpose the Water Pollution Control Law has been issued. According to the Street and Buildings Law, all dwellings must be equipped with a septic tank, followed by an absorption pit. When the pits overflow due to saturation of the soil, the septage is pumped out and transported to a sewage treatment plant for treatment and reuse. Based on land-use zoning, housing developments are not allowed in the vicinity of water-supply sources, rivers and reservoirs. In order to avoid contamination of the water sources from sewage and excreta, protection zones are designated in which the disposal of sewage is not allowed. PMID:10842850

    The main purpose of this study is to provide a simple statistical analysis of several stability indices and parameters for extreme and non-extreme thunderstorm events during the period 1997 to 2001 in Cyprus. For this study, radiosonde data from Athalassa station (35°1´ N, 33°4´ E) were analyzed during the aforementioned period. The stability indices and parameters set under study are the K index, the Total Totals (TT) index, the Convective Available Potential Energy related parameters such as Convective Available Potential Energy (CAPE), Downdraft CAPE (DCAPE) and the Convective Inhibition (CIN), the Vorticity Generator Parameter (VGP), the Bulk Richardson Number (BRN), the BRN Shear and the Storm Relative Helicity (SRH). An event is categorized as extreme, if primarily, CAPE was non zero and secondary, if values of both the K and the TotalTotals (TT) indices exceeded 26.9 and 50, respectively. The cases with positive CAPE but lower values of the other indices, were identified as non-extreme. By calculating the median, the lower and upper limits, as well as the lower and upper quartiles of the values of these indices, the main characteristics of their distribution were determined.

  12. A pricing policy towards the sourcing of cheaper drugs in Cyprus.

    In contrast to other EU countries, Cyprus lacks comprehensive health care coverage for its population, thus a significant portion of the population lacks insurance for medicines. Due to the small size of the country and small indigenous pharmaceutical industry, pharmaceuticals are mainly imported. Prices in the private sector are determined based on the ex-factory price from the country of origin. Distribution margins are calculated as a percentage of the import price, which creates perverse incentives for wholesalers to import products from high price countries, or import very expensive products, to maximize their income. In this article, we compare pharmaceutical prices in Cyprus to other EU counties with higher or similar GDP per capita and found Cyprus to be a high price country. We then propose a new pricing system to change wholesaler incentives, which would encourage them to shop around for the best buy in Europe. Prices can be set based on average prices from a basket of European countries, and adjusted to reflect the GDP per capita level in Cyprus. This will establish the wholesale price that the government will accept, and wholesalers can procure products from any country at a lower rate. Thus, wholesalers would be encouraged to go for the lowest prices and the authorities would be indifferent to the actual price they obtain, so long as the necessary criteria (good manufacturing practice, safety, effectiveness and efficacy) are met. Our proposal has implications for low and middle income countries where this system of pharmaceutical pricing and wholesaler incentives can be used. PMID:16949176

    The Cyprus Arc in the Eastern Mediterranean represents the active collision front between the African and Eurasian (Anatolian) Plates. Along the Cyprus Arc, the Eratosthenes Seamount is believed to have been blocking the northward motion of the African Plate since the Late Pliocene-Early Pleistocene. Based on a dense grid of 2D reflection seismic profiles covering the Eratosthenes Seamount and western Levant Basin offshore Cyprus, new observations regarding the Cyprus Arc collision front at the triple transition zone Eratosthenes Seamount-Levant Basin-Hecataeus Rise are presented. The data show that the Levant Basin is filled with ~ 10 km of sediments of Early Mesozoic (probably Jurassic) to Plio-Quaternary age with only a localized deformation affecting the Miocene-Oligocene rock units. The sediments onlap directly against the steep eastern flank of the Eratosthenes Seamount to the west and the southern flank of the Hecataeus Rise to the north. The sediments show no deformation that could be associated with collision and are undeformed even very close to the two prominent structures. Pinching out of the Base Miocene reflector in the Levant Basin due to onlapping of the Middle Miocene reflector indicates uplift of the Eratosthenes Seamount and the Hecataeus Rise. In contrast to the Messinian Evaporites north of the Eratosthenes Seamount, the salt in the Levant Basin, even close to the Hecataeus Rise, is tectonically undeformed. It is proposed that the Eratosthenes Seamount, the western Levant Basin and the Hecataeus Rise act as one tectonic unit. This implies that the collision front is located north of this unit and that the Hecataeus Rise shields the sediments south of it from deformation associated with collision of the African and Anatolian Plates.

    The study reported in this article examines the nature of relationships between organizational and personal resources and nurses' turnover intentions. A sample of 124 nurses in the Turkish Republic of Northern Cyprus serves as the study setting. Results of the study reveal that a form of organizational support (empowerment) and two personal resources (customer orientation, job resourcefulness) are the best predictors of turnover intentions. Implications of these results are discussed and avenues for future research are offered. PMID:23458483

    In many countries of the world, food demand exceeds the total agricultural production. In semi-arid countries, agricultural water demand often also exceeds the sustainable supply of water resources. These water-stressed countries are expected to become even drier, as a result of global climate change. This will have a significant impact on the future of the agricultural sector and on food security. The aim of the AGWATER project consortium is to provide recommendations for climate change adaptation for the agricultural sector in Cyprus and the wider Mediterranean region. Gridded climate data sets, with 1-km horizontal resolution were prepared for Cyprus for 1980-2010. Regional Climate Model results were statistically downscaled, with the help of spatial weather generators. A new soil map was prepared using a predictive modelling and mapping technique and a large spatial database with soil and environmental parameters. Stakeholder meetings with agriculture and water stakeholders were held to develop future water prices, based on energy scenarios and to identify climate resilient production systems. Green houses, including also hydroponic systems, grapes, potatoes, cactus pears and carob trees were the more frequently identified production systems. The green-blue-water model, based on the FAO-56 dual crop coefficient approach, has been set up to compute agricultural water demand and yields for all crop fields in Cyprus under selected future scenarios. A set of agricultural production and water use performance indicators are computed by the model, including green and blue water use, crop yield, crop water productivity, net value of crop production and economic water productivity. This work is part of the AGWATER project - AEIFORIA/GEOGRO/0311(BIE)/06 - co-financed by the European Regional Development Fund and the Republic of Cyprus through the Research Promotion Foundation.

    Cyprus maintains a population-based cancer registry that allows for in-depth study of cancer in a culturally- and environmentally-unique setting. Using eleven years of collected data (1998-2008), we present the first comprehensive analysis of cancer in Cyprus. We calculated gender-specific, world age-adjusted incidence rates and time trends for the 26 most incident cancers. This study revealed that overall world age-standardized rates among males increased from 195.4 cases per 100,000 in 1998-2002 to 239.0 cases per 100,000 in 2006-2008. For the entire eleven-year period, prostate, lung, colorectal, and bladder cancers were the most incident cancers among males. Among females, the overall world age-standardized rate increased from 180.6 cases per 100,000 in 1998-2002 to 217.1 cases per 100,000 in 2006-2008. Over the entire period, breast, colorectal, uterine, and thyroid were the most incident cancers in females. There were sixteen sex-specific cancers that indicated statistically significant increasing incidence trends over the study period, and no types for which the rate was significantly decreasing. Thyroid cancer illustrated rapid increases in rates. Results were compared to other Mediterranean European registries reported in Cancer Incidence in 5 Continents report for 1997-2002. Overall cancer incidence in Cyprus is lower than that of Southern Mediterranean countries, and given the known environmental risk factors in Cyprus, the low rate of lung cancer is especially interesting. The epidemiologic patterns reported in this study open the door for future etiologic studies to elucidate role of environmental and lifestyle factors of cancer in this population and highlight opportunities for cancer prevention and control.

    This paper aims to highlight the benefits from the integration of wireless sensor network / meteorological data and remote sensing for monitoring and determine irrigation demand in Cyprus. Estimating evapotranspiration in Cyprus will help, in taking measures for an effective irrigation water management in the future in the island. For this purpose both multi-spectral satellite images (Landsat 7 ETM+ and ASTER) and hydro-meteorological data from wireless sensors and automatic meteorological stations have been used. The wireless sensor network, which consist approximately twenty wireless nodes, was placed in our case study. The wireless sensor network acts as a wide area distributed data collection system deployed to collect and reliably transmit soil and air environmental data to a remote base-station hosted at Cyprus University of Technology. Furthermore auxiliary meteorological field data, from an automatic meteorological station, nearby our case study, where used such as solar radiation, air temperature, air humidity and wind speed. These data were used in conjunction with remote sensing results. Satellite images where used in ERDAS Imagine Software after the necessary processing: geometric rectification, radiometric calibration and atmospheric corrections. The satellite images were atmospheric corrected and calibrated using spectro-radiometers and sun-photometers measurements taken in situ, in an agricultural area, south-west of the island of Cyprus. Evapotranspiration is difficult to determine since it combines various meteorological and field parameters while in literature quite many different models for estimating ET are indicated. For estimating evapotranspiration from satellite images and the hydro-meteorological data different methods have been evaluated such as FAO Penman-Monteith, Carlson-Buffum and Granger methods. These results have been compared with E-pan methods. Finally a water management irrigation schedule has been applied. The final results are

    We have compiled a global geological map of Ganymede that represents the most recent understanding of the satellite based on Galileo mission results. This contribution builds on important previous accomplishments in the study of Ganymede utilizing Voyager data and incorporates the many new discoveries that were brought about by examination of Galileo data. We discuss the material properties of geological units defined utilizing a global mosaic of the surface with a nominal resolution of 1 km/pixel assembled by the USGS with the best available Voyager and Galileo regional coverage and high resolution imagery (100-200 m/pixel) of characteristic features and terrain types obtained by the Galileo spacecraft. We also use crater density measurements obtained from our mapping efforts to examine age relationships amongst the various defined units. These efforts have resulted in a more complete understanding of the major geological processes operating on Ganymede, especially the roles of cryovolcanic and tectonic processes in the formation of might materials. They have also clarified the characteristics of the geological units that comprise the satellite's surface, the stratigraphic relationships of those geological units and structures, and the geological history inferred from those relationships. For instance, the characteristics and stratigraphic relationships of dark lineated material and reticulate material suggest they represent an intermediate stage between dark cratered material and light material units.

    Cyprus, the third largest island in the Mediterranean Sea, has never been monolingual. For over four hundred years the two main languages of the island have been Turkish and Greek. Turkish-Cypriots and Greek-Cypriots met each other in the streets, but seldom in the schools. The Greek language had a place in the Turkish-Cypriots' educational system during some periods in history, but the Greek-Cypriots have never given the Turkish language a place in their school system. Until recent years, the majority of Turkish-Cypriots have had communicative competence in Greek. In contrast, there have been very few Greek-Cypriots who had communicative competence in Turkish. The history of Cyprus clearly shows that lack of policies for bilingualism on the island has weakened the good relationship between the two folk groups. The fact that the learning of the global language English is happening to the detriment of the learning of Greek among Turkish-Cypriots makes the integration of the two main cultural groups of Cypriots more difficult. Using the island's historical background, especially the intercommunal dispute during the last four decades as a basis, the author argues for a closer relationship between the economic, social, cultural, including bilingual and educational policy of the two parts of Cyprus. He sees this as the best peace policy for the island.

    An analysis was carried out to determine the presence of enteroviruses and adenoviruses in public swimming pools in Cyprus. The effectiveness of the commonly implemented disinfection procedure of chlorination was confirmed by determination of bacteriological markers. Analysis of viral presence was carried out by sampling random swimming pools from the five major cities in Cyprus during a period of 21 months spanning from April 2007 to December 2008. A 10 I sample was taken from each swimming pool to be tested and was subsequently concentrated via membrane filtration using a new methodological approach for virus elution. Concentrated samples were analysed using of a Real Time Polymerase Chain Reaction (PCR) TaqMan probe based approach to detect the presence of enteroviruses and adenoviruses. Over the period of 21 months a total of 126 swimming pools were sampled and analysed. In four swimming pools enteroviruses were detected, in one pool echovirus 18 was identified, in two pools echovirus 30 was identified and in one other pool poliovirus Sabin 1 was identified. Similarly, in four swimming pools adenoviruses were detected, in all four adenovirus 41 was identified. Bacteriological marker analysis showed that 98% of pools complied with Cyprus regulations.

    A study for a 30-year period (1981-2010) for a new precipitation database is performed over the island of Cyprus. Climate Hazards Group Infrared Precipitation with Station data (CHIRPS) is a more than 30-year quasi-global rainfall dataset, spanning 50°S-50°N (and all longitudes). Starting in 1981 to near-present, CHIRPS incorporates 0.05° resolution satellite imagery with in situ station data to create gridded rainfall time series. In this study, CHIRPS database is firstly compared to other precipitation databases over the Mediterranean basin. In the following, this study focuses over Cyprus, where a dense and reliable network of rain gauges is available. CHIRPS data are compared for the first time with in situ measurements in this area, for the aforementioned 30-year period. Monthly and annual comparisons are presented for each of the 0.05 × 0.05 degree cells overlaying the island of Cyprus. Results showed good correlation between CHIRPS values and recorded precipitation, although an overestimation of the in situ rainfall data has been noted during the last decade.

    Most industries in Cyprus possess permits either for disposal at central wastewater treatment plants (the treated effluent of which is reused or disposed into the sea), or discharge on soil, or reuse either for irrigation or groundwater recharge or discharge into the sea. A preliminary investigation undertaken by the University of Cyprus in regards to dangerous substances was the first step towards establishing a new licensing and monitoring system. Liquid-liquid extraction was used for the extraction of the selected pesticides from wastewaters. Gas chromatography with two different detection methods (ECD and FTD) was applied for the determination of 17 pesticides (12 organochlorine insecticides, 3 organophosphoric insecticides and 2 herbicides). In addition ICP and a mercury evaporation unit were used to determine the concentrations of heavy metals in the samples. The results revealed the presence of several priority substances in wastewaters, in most cases at concentrations well below the regulatory limits. Non-compliance was observed for a limited number of metals. Sixteen out of 17 organic substances that were monitored for 1-year period time were traced in different wastewater streams. What was found out is that there is a need to expand the analytical determinations and the monitoring to more wastewater streams and more priority substances, in order to safeguard the water resources in Cyprus.

    Adobe masonry is part of the vernacular architecture of Cyprus. Thus, it is possible to use this technology in a meaningful way on the island. On the other hand, although adobe architecture is more sustainable in comparison to other building technologies, the use of it is diminishing in North Cyprus. The application of Turkish building code in the north of the island has created complications in respect of the use of adobe masonry, because this building code demands that reinforced concrete vertical tie-beams are used together with adobe masonry. The use of reinforced concrete elements together with adobe masonry causes problems in relation to the climatic response of the building as well as causing other technical and aesthetic problems. This situation makes the design of adobe masonry complicated and various types of ethical problems also emerge. The objective of this article is to analyse the ethical problems which arise as a consequence of the restrictive character of the building code, by analysing two case studies and conducting an interview with an architect who was involved with the use of adobe masonry in North Cyprus. According to the results of this article there are ethical problems at various levels in the design of both case studies. These problems are connected to the responsibilities of architects in respect of the social benefit, material production, aesthetics and affordability of the architecture as well as presenting distrustful behaviour where the obligations of architects to their clients is concerned.

    Haemoglobinopathies are the most common monogenic diseases, posing a major public health challenge worldwide. Cyprus has one the highest prevalences of thalassaemia in the world and has been the first country to introduce a successful population-wide prevention programme, based on premarital screening. In this study, we report the most significant and comprehensive update on the status of haemoglobinopathies in Cyprus for at least two decades. First, we identified and analysed all known 592 β-thalassaemia patients and 595 Hb H disease patients in Cyprus. Moreover, we report the molecular spectrum of α-, β- and δ-globin gene mutations in the population and their geographic distribution, using a set of 13824 carriers genotyped from 1995 to 2015, and estimate relative allele frequencies in carriers of β- and δ-globin gene mutations. Notably, several mutations are reported for the first time in the Cypriot population, whereas important differences are observed in the distribution of mutations across different districts of the island.

    The endemic Cyprus Scops Owl Otus (scops) cyprius has been treated as a subspecies of the widespread Eurasian Scops Owl O. scops since at least the 1940s. However, its song is distinct from that of all other subspecies of O. scops in being double-noted, rather than single-noted. Its plumage also differs, most obviously in being consistently darker than other subspecies and in lacking a rufous morph. However, it shows no biometric differences from O. s. cycladum and southern populations of O. s. scops. It is also unusual among scops (s. l.) populations in being at least partially resident, although two specimens showing characters of this taxon were collected in Israel in early spring, and the numbers of birds that are resident on Cyprus appear to vary, with few recent winter records. It differs from O. s. scops by one synapomorphic nucleotide exchange in the analysed mitochondrial marker, indicating a recent separation. Given that large numbers of O. s. scops and O. s. cycladum pass through Cyprus on spring migration, and that the latter breeds in adjacent countries, it seems probable that cycladum would colonize the island, but for the presence of cyprius. That it does not do so, and that cyprius retains its distinctive song and plumage, suggests that isolating mechanisms exist. We recommend that cyprius be considered specifically distinct, as are other distinctively voiced insular Otus populations. PMID:26624667

    During very early stages of accretion, small continental blocks collide together and this process of continental accretion is not at all uniform. The study here focuses on the accretion of Eratosthenes Seamount (Southern Offshore Cyprus), a carbonate platform on a rifted sliver of continental crust colliding to another continental crust, Cyprus since Late Pliocene-Early Quaternary. Factors that control the process of accretion, geometry of foreland basins, back thrusting, and changes in structural style during the continental collision is linked to variations in Effective Elastic Thickness (EET). A variable EET map (across the strike of the subduction boundary as well as down dip) is computed for Eratosthenes Seamount. Modeled flexure deflection is matched to seafloor bathymetry, Cyprus topography, and marine Bouguer gravity anomalies. The hypothesis we are testing is that the accretion is more advanced at places where change in EET values is lower compared to the immediate vicinity. Calculated EET of the Eratosthenes Seamount is done using an elastic half-beam model.

    It is well known that green spaces are vital for increasing the quality of life within the urban environment. World Health Organization states that it should be 9 square meters per person at least. European Environment Agency defines that 5000 square meters of green space should be accessible within 300 meters distance from households. Green structure in Northern Cyprus is not sufficient and effective in this manner. In Northern Cyprus, they have neglected the urban planning process and they have started to lose significance and importance. The present work analyzes the accessibility of green spaces in Northern Cyprus cities. Kioneli, Famagusta, Kyrenia and the northern part of Nicosia are analyzed in this manner. To do that, green space structure is analyzed by using digital data. Additionally, accessibility of the green space is measured by using 300-meter buffers for each city. Euclidean distance is used from each building and accessibility maps are generated. Kyrenia and Famagusta have shortage in green space per capita. The amount of green space in these cities is less than 4 square meters. The factors affecting the accessibility and utilization of public spaces are discussed to present better solutions to urban planning.

    Waste from electrical and electronic equipment (WEEE) constitutes one of the most complicated solid waste streams in terms of its composition, and, as a result, it is difficult to be effectively managed. In view of the environmental problems derived from WEEE management, many countries have established national legislation to improve the reuse, recycling and other forms of recovery of this waste stream so as to apply suitable management schemes. In this work, alternative systems are examined for the WEEE management in Cyprus. These systems are evaluated by developing and applying the Multi-Criteria Decision Making (MCDM) method PROMETHEE. In particular, through this MCDM method, 12 alternative management systems were compared and ranked according to their performance and efficiency. The obtained results show that the management schemes/systems based on partial disassembly are the most suitable for implementation in Cyprus. More specifically, the optimum scenario/system that can be implemented in Cyprus is that of partial disassembly and forwarding of recyclable materials to the native existing market and disposal of the residues at landfill sites.

    The olive fruit fly Bactrocera oleae (Gmelin) (Diptera: Tephritidae) is the most important pest of olives in countries around the Mediterranean basin. Its control has been based mostly on bait sprays with organophosphate insecticides (usually dimethoate or fenthion) for about 40 years. In the present study, the resistance status of olive fruit fly populations to dimethoate was examined in Greece and Cyprus over 2 years. Thirty-one populations from various regions of Greece, nine from Cyprus and one laboratory susceptible strain, which served as a control, were assayed by topical application of dimethoate. Considerable variation in the resistance levels to dimethoate was recorded in the populations of B. oleae, with resistance ratios ranging from 6.3 to 64.4 (ED(50) values 12.5-128.7 ng dimethoate per insect). The highest resistance ratios were found in populations from Crete, and the lowest in those from Cyprus. This variation could be attributed to different selection pressures from insecticidal applications among populations from the various regions. Migration of resistant genotypes, either autonomous or via commerce, may also be involved. PMID:17103369

    Rocks form under a variety of geologic settings and conditions, thus the mineral composition, texture, structures and stratigraphic relationships of exposed rocks provide geologists a means to access information about the past geologic and climatic history. Typically, tectonic events (e.g., orogenic) and erosional processes expose sections of older terrestrial rocks at the surface. On Mars, a lack of complex tectonics and lower erosion rates make these tectonic exposures virtually non-existent. Impacts, however, generate localized displacements and structural uplift of target rocks and exposes them within the crater rim, walls, terraces and central structural uplifts. Imagery from the High Resolution Imaging Science Experiment (HiRISE) of this Crater-Exposed Bedrock (CEB) reveals unprecedented meter to decameter textural and structural detail [1]. Our initial work, based on previous efforts [1-3], has revealed that not all craters are well exposed due to impact melt coatings and ongoing degradation, infilling, and mantling of crater rims, floors and walls. Thus, making a database (DB) of craters with good exposures is an essential step towards understanding the spatial and temporal distribution of CEB textures, structures and compositions. When complete, the DB will aid our ability to make inferences regarding the petrogenesis, evolution and geologic history of the upper crust at regional and potentially global scales. Our CEB DB will be used to focus on spectral units that specifically correlate with CEB textures and stratigraphic relationships. Our preliminary results suggest that CEB can be classified into three textural categories, 1) Megabreccias (MB), 2) Intact layered Stratigraphy (IS), and 3) a massive textured Fractured Bedrock (FB), with each of these classifications being informative with respect to a specific geologic setting or possible set of histories (e.g., late-heavy bombardment, cyclical volcanism and sedimentation).

    The Levant Basin is bounded to the north by the Cyprus Arc zone which was created by the northward movement of the African plate with respect to the Eurasian plate since Late Cretaceous time. The westward movement of the Anatolian micro-plate since Late Miocene created an additional strike-slip component along the plate boundary. The main objective of this contribution is to portray the structural architecture and features offshore Cyprus by analyzing available 2D seismic data in order to investigate the transition in tectonic style from compression to strike slip along the Cyprus Arc zone. We identified three different crustal domains offshore Cyprus that are from east to west: the eastern domain which belongs to the Levant Basin, the South-central domain which includes the Eratosthenes Seamount, and the South-West domain of Cyprus which corresponds to the Herodotus Basin. In the Levant Basin, the sequences identified are from Base Pliocene extending until the Senonian unconformity. The same sequences in the Cyprus Basin are offset and less thick due to the movement of the Latakia Ridge, which is identified as a steeply dipping sub-vertical fault on our data. In the central domain, the horizons identified on the Eratosthenes Seamount indicate that the Seamount is a Mesozoic carbonate platform covered by thin Miocene/Plio-Pleistocene sediments. A subdivision of the sedimentary sequence in the Herodotus Basin is proposed down to the Paleocene-Eocene basis. A major change in the structural style of the deformation is observed form west to east. Whereas the Levant Basin is almost undeformed south of the Latakia Ridge, several structures were mapped in the central domain, like flexural basin, pop-up structures and back-thrusts. South-verging thrusts were also, identified in the Cyprus Basin. All these structures show a Pliocene activity. Our data suggest that the heterogeneity of the crustal structure played a major role in the longitudinal evolution of the plate

    Porous limestone is widely used as construction material in the monuments of Cyprus and Hungary. The present study compares the physical properties of a bioclastic limestone from Cyprus and an oolitic limestone from Hungary. Petra Gerolakkou is a Pliocene limestone from Cyprus that originates from the district of Nicosia, the island's capital. It has been extensively used throughout the years in construction and restoration projects, particularly in the Nicosia area. Distinctive examples of its use can be found in the majority of the most important historic monuments in Nicosia, such as the Venetian walls and fortifications, churches (e.g. the Agia Sofia Cathedral), the archbishop and presidential palaces and a high number of other traditional buildings. The studied Miocene limestone from Hungary was exploited from Sóskút quarry (15-20 km W-SW to Budapest). The quarry provided stone for emblematic monuments of the capital of Hungary such as the Parliament building, Mathias Church, the Opera House and Citadella. In this study, mechanical parameters for both aforementioned stones, such as uniaxial compressive and tensile strengths, were tested under laboratory conditions. Their density, porosity and water absorption were also compared. The studied limestone from Cyprus exhibits porosity values within the range of 48-51%, apparent density between 1340 and 1400 kg/m3 and strength values under uniaxial compressive load between 1.2 and 2.8 MPa. This lithotype is also considered susceptible to salt decay, since an approximate mass loss of 12.5% is noted after 15 salt crystallization artificial weathering cycles. The porosity of the Hungarian limestone is in the order of 16-35%, the bulk density is 1600-1950 kg/m3, while the compressive strength is 2.5-15 MPa. Durability tests indicate that even after 10 freeze-thaw cycles the loss in strength is dramatic. Test results indicate that use of porous limestone in both countries is common and fabric strongly controls the

    Background and aims The most common thyroid disorders, with an increasing detection worldwide, are the thyroid nodules and thyroiditis, which leads to an increase of thyroid cancer incidence . In two different countries with a different exposure to risk factors for thyroid cancer, such as Cyprus and Romania, the rank of thyroid cancer among other neoplasms is very different: the 3rd most prevalent cancer among females in Cyprus and the 12th in Romania, respectively. Environmental chemicals, such as bisphenol A have a proven effect on the thyroid function. However, the relation between the exposure to the endocrine disruptor and the development of thyroid nodules, with a potential of malignant transformation has not been previously studied. The aim of the study was to investigate the potential factors that lead to the difference of thyroid nodules incidence in the mentioned countries. Methods A pilot case-control study has been conducted in 2014–2015 in the “Prof. Dr. Ion Chiricuţă” Institute of Oncology, Cluj-Napoca, Romania and the Endocrinology Department of Archbishop Makarios III Hospital, Nicosia, Cyprus. Females older than 20 years with no medical history were recruited. Cases were women with ultrasound-confirmed thyroid nodules of size >3mm. Controls were women without thyroid nodules after ultrasound confirmation. All participants provided blood samples for measurements of the thyroid stimulating hormone (TSH), free thyroxin (FT4), anti-thyroglobulin (ATg) and anti-thyroid peroxidase (ATPO); urine samples. Demographics, anthropometrics and other relevant information were provided through the administration of a questionnaire. Results In Romania we selected 51 patients with thyroid nodules (case group) and 41 without thyroid nodules (control group) and in Cyprus 57 cases, respectively 65 controls. After the statistical analysis of the data collected we observed statistically significant differences between the populations of the two countries

    Salt tectonics and mud volcanism in the Latakia and Cyprus Basin, eastern Mediterranean, is investigated by means of swath sounding, reflection seismics and side-scan data as well as by camera and video sledge observations. Both basins are located east of Cyprus and are associated with the collision front between the African and Anatolian plate. The Pliocene-Quaternary sediment succession is underlain by up to 1 km thick Messinian evaporites. Both thick-skinned plate tectonic and thin-skinned salt tectonic control fluid dynamics and associated mud volcanism in the Latakia and Cyprus Basin as well as at the Troodos Latacia Culmination, which separates both basins. An end-member model is proposed which explains the presence of elongated topographic highs and trenches along the Troodos Larnaca Culmination and south of it by gravity gliding of the Messinian evaporites and associated fluid migration. Thin-skinned extension in the Troodos Larnaca Culmination and boudinage, respectively, facilitate fluid flow through and out of the evaporites. The fluid or mud flow dissolutes the salt layer and creates elongated trenches. Mud intrudes into the Pliocene-Quaternary sediments above the trenches. Consequently, the overburden is thickened and forms morphological ridges. South of the culmination the evaporites and overburden are folded due to thin-skinned shortening of the evaporites. In one instance fluid extrusion out of the evaporites is inferred from seismic data interpretation. The outflow caused a volume reduction and collapse of the evaporites. Mud volcanoes and fold anticlines align above deep-rooted transpressional fault systems which are associated with the African-Anatolian collision zone. The faults may act as conduits for rising fluids. In the western part of the survey area, where the Cyprus Arc strikes almost West-East and the collision occurred more frontal and stress was highest, mud volcanoes emerged. Further to the east, where the Cyprus Arc runs SW-NE and

    Cyprus does not have a National Food Safety Authority (NFSA), but a multi-level, fragmented system with responsibilities divided among different ministries and governmental agencies, frequently impeding efforts to effectively manage food risks by duplication and overlapping of responsibilities. A population-based survey was carried out to determine the beliefs and attitudes of interested parties concerning the establishment of a NFSA in Cyprus. Information was collected using a random stratified sampling design and a structured questionnaire. A total of 868 questionnaires were collected (704 from regular consumers, 154 from food businesses' representatives, and 10 from public services' directors or acting head officers). About 11% of food businesses' representatives and 45% of consumers reported that they did not know which public authorities are responsible for food control. Moreover, 2 out of 10 (17%) of responders from public agencies, 70% from food businesses and 91% from consumers, although not aware of ongoing efforts to establish a food safety authority in Cyprus (currently under consideration), were supportive of the idea [8 out of 10 (83%) of responders from public services, 93% from food businesses, and 89% of consumers]. Finally, 7 out of 10 (67%) from the public agencies and 84% of representatives from food businesses agreed with the separation of risk assessment from risk management activities. Public opinion in Cyprus as well as public agencies and food businesses' representatives support the establishment of a single independent national food safety authority in Cyprus based on the European paradigm including the division of risk activities.

    The potential for migration of contaminated ground water from the US Department of Energy Savannah River Site (SRS) beneath the Savannah River into Georgia (trans-river flow) is a subject of recent environmental concern. The degree of incision of the ancestral Savannah River into the local hydrogeologic framework is a significant consideration in the assessment of trans-river flow. The objective of this investigation is to identify the geologic formations which subcrop beneath the alluvium and the extent to which the river has incised regional confining beds. To meet this objective 18 boreholes were drilled to depths of 25 to 100 feet along three transects across the present floodplain. These borings provided data on the hydrogeologic character of the strata that fill the alluvial valley. The profiles from the borehole transects were compared with electrical conductivity (EM-34) data to ascertain the applicability of this geophysical technique to future investigations.

    Mangala Vallis one of the large outflow channels that channeled large quantities of water into the northern lowlands, long ago on geological timescales. This valley is one of the few in the southern hemisphere, as well as one of the few west of the Tharsis bulge. A closer look at the channel shows more recent weathering of the old water channel: the walls of the channel show small, dark slope streaks that form in dusty areas; and much of the surrounding terrain has subtle linear markings trending from the upper left to the lower right, which are probably features sculpted and streamlined by the wind. Geology still shapes the surface of Mars today, but its methods over the eons have changed.

    The objective of the present study was to evaluate the distribution, sources, origins, and environmental risk assessment of polycyclic aromatic hydrocarbons (16 US EPA priority pollutants) pollution in 23 surface sediments from Cyprus coast. The mean total polycyclic aromatic hydrocarbons (PAHs) concentrations in the sediments from Gemi Konagi, Girne and Gazi Magusa areas were found 47, 52 and 50 ng/g, respectively. Molecular ratios and principle component analysis indicated that PAH pollution originated mainly from fossil sources, with higher pyrolytic contributions. The 2-3 ring PAHs were dominant in Cyprus sediments. Concentrations of PAHs observed in this study were compared with available soil quality guidelines and the concentrations were lower than the guideline values. The guideline values suggested that the Cyprus sediments were likely to be not contaminated by toxic PAH compounds. PMID:23948089

    We compared and assessed the results of measurements and observations by the Lunokhod 1 and Yutu rovers, both of which explored the northwestern part of Mare Imbrium. Both sites are within the distinctive Eratosthenian-aged lava flow geologic unit and our comparisons showed that the geologies of these exploration sites are very similar. As in the majority of other areas of the Moon, the dominant landforms in these sites are small impact craters, having various degrees of morphologic prominence and states of preservation, and rock fragments, mostly associated with the rims and interiors of fresh craters. The shape and the degree of preservation of the observed rock fragments in these two sites are similar. In both sites sporadic rock fragments were observed whose morphologies suggest that their source rocks had columnar jointing. Localization of these specific rocks on the rims of 450-470 m in diameter craters implies that the source rocks are at depths of 40-50 m. Regolith in the study areas is typically a few meters thick, but locally can be much thicker. The ground penetrating radar of the Yutu rover revealed the multilayer regolith structure, which is determined by superposition of crater ejecta; with some local variations, this type of the regolith stratigraphy should be typical of the majority of lunar mare sites. The physico-mechanical properties of the regolith in these two sites appear to be rather similar: the bearing capacity ranges from 0.04 to 1.44 kg/cm2, with a modal value ∼0.45 kg/cm2, and the shear strength ranges from 0.02 to 0.1 kg/cm2, with a modal value ∼0.05 kg/cm2. Both these factors decrease by a factor of 3-4 with an increase of surface slope from ∼2 to 12°. The chemical composition of surface materials determined by the rover instruments at these two sites differ from those derived from the remote sensing data for the Eratosthenian-aged basalts on which the two sites are located. This could be partly due to low measurement accuracies

    Expanded energy- and recreation-related activities in the Yampa River basin, Colorado and Wyoming, have caused a rapid increase in economic development which will result in increased demand and competition for natural resources. In planning for efficient allocation of the basin 's natural resources, Landsat images and small-scale color and color-infrared photographs were used for selected geologic, hydrologic and land-use applications within the Yampa River basin. Applications of Landsat data included: (1) regional land-use classification and mapping, (2) lineament mapping, and (3) areal snow-cover mapping. Results from the Landsat investigations indicated that: (1) Landsat land-use classification maps, at a regional level, compared favorably with areal land-use patterns that were defined from available ground information, (2) lineaments were mapped in sufficient detail using recently developed techniques for interpreting aerial photographs, (3) snow cover generally could be mapped for large areas with the exception of some densely forested areas of the basin and areas having a large percentage of winter-season cloud cover. Aerial photographs were used for estimation of turbidity for eight stream locations in the basin. Spectral reflectance values obtained by digitizing photographs were compared with measured turbidity values. Results showed strong correlations (variances explained of greater than 90 percent) between spectral reflectance obtained from color photographs and measured turbidity values. (Woodard-USGS)

  7. Building and Applying "Insularity Theory": Review on Knapp's Prehistoric and Protohistoric Cyprus, 2008.

    NASA Astrophysics Data System (ADS)

    Katsarou-Tzeveleki, Stella

    Prehistoric and Protohistoric Cyprus by A. Bernard Knapp involves us in a highly creative reading. This is due mainly to the fact that the author engages in a holistic synthesis of Cyprus in the Bronze Age, not by emphasizing the events and descriptions of the material remains, but by concentrating upon the difficult question of the identity of the islanders of this period and the processes by which it was formed. The author's teaching of Mediterranean prehistory at the University of Glasgow fully accounts for his need to produce a comprehensive theoretical work of this kind: the basic questions asked by students give rise to theoretical concerns for any teacher aiming to 'distil' the essential synthesis that forms the starting point for any further detailed archaeological description. This essential answer seems to have troubled Knapp for some time, judging by the long list of his writings seeking to synthesize aspects of Cypriot economy, cult and society; the present book is thus the highly interesting outcome of the mature thinking of an experienced fieldworker as much as a theoretical archaeologist and teacher. What, then, is the essential question that Knapp seeks to answer through this book? His question focuses on the identity of the islanders of Cyprus during the 'most formative periods, from the village based culture to the international, town-centred, even state-level polity' (p. 1), the way in which this identity was formed, and how it is reflected in both any recorded event and the material culture of the island in this specific period. Moreover, he also explores more fully what the distinctive features of island identity in general are, how they are constituted and how they influence the material culture of any island population. In seeking the answers, the author avoids a number of the usual approaches to Cypriot archaeology and turns, instead, to new interpretive directions. The approaches he avoids are the citing of events of Cypriot prehistory, the

    There is a need for spatially denser and temporally more detailed observations of precipitation in most countries, including Cyprus. Traditionally, rainfall is measured with rain gauges that are either read manually once a day or automatically at higher temporal frequencies. However, these are point measurements with poor spatial representativeness due to the small sampling area. In Cyprus rain gauges are typically installed close to populated communities and built-up areas, leaving substantial parts of the country only sparsely covered. On the other hand, wireless communication networks are widely spread across the terrain, at heights of only a few tens of meters off the surface. The microwave links, used in these networks, are deployed by cellular providers for backhaul communication between base stations. Since these links operate at frequencies of tens of GHz, atmospheric conditions and particularly rainfall affect the electromagnetic channel causing attenuations to the microwave signals between the radio masts. Cellular networks infrastructures can therefore be regarded as relatively high-precision atmospheric observation system offering fairly dense spatial coverage and high temporal resolution. The principal feasibility of rainfall delineation by microwave attenuation between commercial radio links has been shown by Messer et al. (2006). In the meantime, the group of P. Alpert and H. Messer at Tel Aviv University, and additional groups around the world (e.g. Leijnse et al 2010; Chwala et al., 2012; Wang et al., 2012 ) have further developed the methodology. The objectives of the current project, which is still being implemented, can be summarized as follows: i. to carry out a feasibility study on the utilization of mobile-phone-link-data for rainfall observations in Cyprus; ii. to evaluate, adapt and implement the analysis methodology/software developed and used at TAU at the Energy, Environment and Water Research Center of The Cyprus Institute; iii. to

    The island of Cyprus, located in the high-oligotrophic region of the eastern Mediterranean, provides an appealing ground for the study of coastal ecosystems under limiting and contrasting environmental conditions. If proper management strategies are to be enforced, the changes on the structure and functioning of marine ecosystems in response to natural and anthropogenic disturbances need to be considered. In this paper, we describe the 2012 coral mortality event along the coast of Cyprus, including selected sites where land-based human activities are likely to have a direct impact on coral habitats. The 2012 event seems to have been induced by prolonged seawater temperature increases during a period of several weeks in summer (in August and September), representing the highest warming event of the last 30 years in Cyprus. Using image-analysis software, Cladocora caespitosa colonies were evaluated by measuring and comparing the area-percentage of healthy tissue, affected tissue (bleached and freshly necrotic) and bare skeleton (older mortality events). The photographic record was acquired during and one month after the warming event through systematic diving transects. Additionally, a public call for collaboration was issued and recreational divers contributed with photographs of corals with different levels of affectation (from none to severe). At the nutrient-affected sites, macroalgae and other filter feeder organisms compete with corals for space, resulting in higher partial-tissue mortality. Despite this fact, coral colonies are more abundant in those sites, which might be explained by the anthropogenic change of naturally limiting conditions (oligotrophy) of Cypriot waters and the physiology of the particular coral species (auto- vs. heterotrophy). Our results suggest that corals under artificially induced conditions (more commonly found elsewhere in the Mediterranean) respond to environmental disturbances impaired by the macroalgae-dominated community
