    Full Text Available Magnetic susceptibility (MS is currently used as a directly representative proxy for the study of climatic variations, and for cyclostratigraphic studies. It depends on the concentration of magnetic minerals in the rocks, but does not allow identifying the magnetic minerals. In the case of argillaceous sediments, the paramagnetism of clay particles often plays a major role in determining the magnitude of their magnetic susceptibility, while the presence of ferrimagnetic iron oxides or sulfides cannot be assessedusing susceptibility measurements alone. Among the different methods that can be used to detect ferrimagnetic particles magnetic viscosity (MV characterizing the delay corresponding to the acquisition or loss of induced magnetization, has the same advantages as MS. Itsmeasurement is direct, rapid and has been proven to be very efficient in detecting the presence of secondary ferrimagnetic minerals in soils. A MV measurement technique was tested on cores taken from a borehole, in Callovian-Oxfordian formations in the eastern Paris Basin (France (Fig. 1. Although the MV values are very small, they have cyclic variations of which strongest values are found at the base of the Lower Oxfordian. These values, when correlated to MS,Gamma Ray (GR and a sequential interpretation of a borehole drilled close-by are found to be associated with the maximum clay fraction in the core samples, a MS maximum, and a major transgression event. Consequently, a significant increase in ferrimagnetic minerals can be associated with this event.

    First is given a broad description of the uses of radioactive tracers in Sedimentology. The general method is established, including determinations of probability and standard deviation. Following are determined: the response law of the detector, the minimum mass for statistical detection, and the minimum mass for dynamic detection. The granularity is an important variable in these calculations. Final conclusions are given, and results are compared with existing theories

  4. Radioisotopes in sedimentology

    1967-01-01

    Radioisotopes have two main uses in sedimentology: they are used for the study of sediment movements in rivers and seas, and for continuous measurements of the amount of sediment suspended in a given medium. These two uses are considered in detail, and brief accounts given of some other uses. Study of sediment movements. After describing the basic technique used in sediment movement studies (injection of a labelled sediment or a simulator into the current, followed by tracking the radioactivity), the author enumerates as fully as possible the problems that can be solved with the help of this technique. Essentially, these problems fall into two groups: 1. Problems related to civil engineering works in coastal areas: the siltation of harbour channels and docks, the formation of banks and bars, the choice of sites for disposing of dredged sediment, the siting of ports, coastline protection, etc. Problems associated with civil engineering works in and near rivers; siting of the water intakes of hydroelectric and nuclear power stations, the effects of construction work on the transport of solids, the construction of dams, the protection of river banks, the construction of jetties, the siltation of lakes, etc. Problems common to these include the transport of effluent and the calibration of hydraulic models. The bibliography is based mainly on fairly recent references and on current research work. 2. Problems related to basic or applied research conducted mainly by universities and research centres: the study of the Quarternary of a particular region, pure sedimentology, the investigation of major sediment transport currents, the confirmation or refutation of transport theories, research into fundamental transport phenomena associated with channel experiments. After referring to the possible exploitation of natural tracers (contained in radioactive waste and fallout), the author discusses the technical aspects of using artificial tracers: the choice of radioisotope

    Milankovitch cycles (obliquity, eccentricity and precession) result in changes in the distribution of solar energy over seasons, as well as over latitudes, on time scales of ten thousands of years to millions of years. These changing patterns in insolation have induced significant variations in Earth's past climate over the last 4.5 billion years. Cyclostratigraphy and astrochronology utilize the geologic imprint of such quasi-cyclic climatic variations to measure geologic time. In recent years, major improvements of the Geologic Time Scale have been proposed through the application of cyclostratigraphy, mostly for the Mesozoic and Cenozoic (Gradstein et al., 2012). However, the field of Paleozoic cyclostratigraphy and astrochronology is still in its infancy and the application of cyclostratigraphic techniques in the Paleozoic allows for a whole new range of research questions. For example, unraveling the timing and pacing of environmental changes over the Late Devonian mass extinction on a 105-year time-scale concerns such a novel research question. Here, we present a global cyclostratigraphic framework for late Frasnian to early Famennian climatic and environmental change, through the integration of globally distributed sections. The backbone of this relative time scale consists of previously published cyclostratigraphies for western Canada and Poland (De Vleeschouwer et al., 2012; De Vleeschouwer et al., 2013). We elaborate this Euramerican base by integrating new proxy data -interpreted in terms of astronomical climate forcing- from the Iowa basin (USA, magnetic susceptibility and carbon isotope data) and Belgium (XRF and carbon isotope data). Next, we expand this well-established cyclostratigraphic framework towards the Paleo-Tethys Ocean, using magnetic susceptibility and carbon isotope records from the Fuhe section in South China (Whalen et al., 2015). The resulting global cyclostratigraphic framework implies an important refinement of the late Frasnian to

    A consistent chronostratigraphic framework is required to understand the effect of major paleoclimate perturbations on both marine and terrestrial ecosystems. Transient global warming events in the early Eocene, at 56-54 Ma, show the impact of large-scale carbon input into the ocean-atmosphere system. Here we provide the first timescale synchronization of continental and marine deposits spanning the Paleocene-Eocene Thermal Maximum (PETM) and the interval just prior to the Eocene Thermal Maximum 2 (ETM-2). Cyclic variations in geochemical data come from continental drill cores of the Bighorn Basin Coring Project (BBCP, Wyoming, USA) and from marine deep-sea drilling deposits retrieved by the Ocean Drilling Program (ODP). Both are dominated by eccentricity-modulated precession cycles used to construct a common cyclostratigraphic framework. Integration of age models results in a revised astrochronology for the PETM in deep-sea records that is now generally consistent with independent 3He age models. The duration of the PETM is estimated at ˜ 200 kyr for the carbon isotope excursion and ˜ 120 kyr for the associated pelagic clay layer. A common terrestrial and marine age model shows a concurrent major change in marine and terrestrial biota ˜ 200 kyr before ETM-2. In the Bighorn Basin, the change is referred to as Biohorizon B and represents a period of significant mammalian turnover and immigration, separating the upper Haplomylus-Ectocion Range Zone from the Bunophorus Interval Zone and approximating the Wa-4-Wa-5 land mammal zone boundary. In sediments from ODP Site 1262 (Walvis Ridge), major changes in the biota at this time are documented by the radiation of a second generation of apical spine-bearing sphenolith species (e.g., S. radians and S. editus), the emergence of T. orthostylus, and the marked decline of D. multiradiatus.

    Constructing an accurate timeline is critical for reconstructing the Earth systems through critical transitions in climate, geochemistry, and life. Existing dates constrain synchronous initiation (ca. 717 Ma) and termination (ca. 660 Ma) of the Sturtian glaciation from multiple continents. The termination of the younger Marinoan glaciation is also well dated at ca. 635 Ma, but the onset of this glaciation is only roughly constrained as ≤ ca. 654 Ma (South China) and ≥ ca. 639 Ma (Namibia). To test if the Marinoan glaciation started close to ca. 654 Ma or ca. 639 Ma, we have conducted a cyclostratigraphic study on the Cryogenian non-glacial Datangpo Formation that conformably overlies and underlies Sturtian and Marinoan glacial diamictites, respectively, in a deep-water basin section in South China. A total of 28,765 magnetic susceptibility (MS) measurements from a drillcore of the 292-m-thick, muddy siltstone- and shale-dominated Datangpo Formation are used for cyclostratigraphic analysis. The results reveal significant decameter- to meter-scale sedimentary cycles of 16-12 m, 3.6-3.0 m, 1.0-0.8 m, and 0.6-0.4 m. The ratios of these cycle wavelengths match well with those of the Milankovitch cycles calibrated for the Cryogenian Period. The established astrochronologic time scale suggests that the duration of the Datangpo Formation is about 9.8 million years. Together with the radiometric age of ca. 660 Ma for the termination of the Sturtian glaciation, the cyclostratigraphic data suggest that the Nantuo (Marinoan) glaciation in South China initiated at ca. 650 Ma, which is slightly younger than but consistent with the ca. 654 Ma U-Pb age from the top of the Datangpo Formation in shelf sections. This age, however, is significantly older than the ages obtained from Marinoan-age glacial diamictites in South China (ca. 636 Ma) and Namibia (ca. 639 Ma). Given that most of the shelf sections may have suffered from glacial erosion, obtaining the onset age of the

    There was no volcano in Precambrian and Mesozoic eras in Iran, but in most place of Iran during the next eras volcanic rocks with green series and Dacites were seen. By the recent survey in Sahand mountain in NW of Iran volcanography, determination of rocks and the age of layers were estimated. The deposits of Precambrian as sediment rocks are also seen in the same area. All of volcanic periods in this place were studied; their extrusive rocks, their petrography and the result of their analytical chemistry were discussed. Finally volcano sedimentology of Sahand mountain were described

    The use of sedimentological reservoir analysis techniques adapted from standard oilfield practice can improve the efficiency and reduce the costs of the evaluation of groundwater aquifers and the design of restoration programs. An evaluation/restoration program at a site in California drilled over 200 test wells in about 750 ac. All wells were logged lithologically and with wireline. The shallow aquifer is a complex braided alluvial floodplain deposit of Late Quaternary age. Analysis demonstrates depositional and erosional responses to periodic hinterland uplifts and to changing climatic conditions. Channel, overbank, lacustrine, and minor deltaic deposits can be recognized. The aquifer architecture has been interpreted to explain the movement of fuel and halogenated hydrocarbon solvents in the sediments and water. Routine engineering geology techniques and hydrologic tests were used to evaluate contamination and to design experimental restoration processes. As demonstrated here, sedimentological techniques show promise in reducing the costs and time required for this type of study. The abundant detailed data will be used in an attempt to develop a microcomputer-based expert system for rapid preliminary analyses of similar aquifers or reservoirs

    In the first part, developments in the use of radioactive tracers in sedimentology are recalled together with the corresponding fields of application and the identities of the main users. The state-of-the-art in France is also discussed; The main characteristics of the method are then described and compared with those of more classical methods. The results that can be obtained with tracer methods are then outlined. The criteria employed to establish the granulometry characteristics of the tracer, the particular radioisotope to be used, and the masses and activities involved, are treated. A list is then given of the main isotopes available in France and their characteristics. The various different labelling techniques employed are studied together with their respective advantages and disadvantages. The special case of pelitic sediments is mentioned. The use of reduced model isotope generators, double labelling and applications to studies of the mud plug in the Gironde Estuary are also discussed. The methods and materials used for injecting and detecting tracers are described, emphasis being given to the economic factors associated with the use of radioactive tracers in sedimentology. The second part of the report contains two chapters: - studies of transport by driftage: presentation and analysis of results and the application of the Count Rate Balance method to obtain quantitative information on transport; - studies of in-suspension transport of fine sediments in the sea: the procedures adopted from the moment when the tracer is introduced up to the time when the results are analyzed and interpreted, enables the trajectories and mean velocities of the transported sediments to be determined together with their degree of dilution and their settling speeds and rates; it is also possible to investigate the evolution and horizontal dispersion of the sediments in this way. Results from recent experiments are presented in both parts of the report

    different sciences as the Structural Processes Group at the Departments of Geodynamic and Sedimentology (University of Vienna) and the Geometric Modelling and Industrial Geometry group (3D technology at the Vienna University of Technology). Interdisciplinary collaboration with other scientists is essential in modern times. Statistical analysis of the orientation and relative position (e.g. imbrication) of the ammonoid shells can hint to current or transport directions. 3D modelling of calcite-cement distribution (representing geopedal structures) and post-diagenetic calcite-veins displacing several ammonoids will complete the geometrical reconstruction and shed light on the biostratinomic and additional diagentic processes. The combination in analysing different fossil groups with additional analysis of istotopic, magnetostratigraphic, cyclostratigraphic and geochemical features will help to extract details of the Upper Triassic history around one of the most severe crisis in the Mesozoic time, the Carnian Crisis. Investigations, undertaken at sections (e.g. Asagiyaylabel) possessing this time interval, can work as proxy for the major Upper Triassic Tethyan crisis. Environmental changes as displayed by the sea level and climate can become more obvious and the ‘motor' behind the demise better understood.

    This June 16, 2000 image of Istanbul, Turkey show a full 60 by 60 km ASTER scene in the visible and infrared channels. Vegetation appears red, and urban areas blue-green. Bustling Istanbul, with its magnificent historical heritage, has spanned the divide between Europe and Asia for more than 2,500 years. Originally called Byzantium, the city was founded in the 7th century BC on the Golden Horn, an arm of the narrow Bosporus (also spelled Bosphorus) Strait, which connects the Sea of Marmara to the south, with the Black Sea to the north. Constantine I made it his capital of the Eastern Roman Empire in AD 330. As Constantinople, the strategically located city arose as the preeminent cultural, religious, and political center of the Western world. It reached the height of its wealth and glory in the early 5th century. After centuries of decline, the city entered another period of tremendous growth and prosperity when, as Istanbul, it became the capital of the Turkish Ottoman Empire in 1457. Although Turkey moved its capital to Ankara in 1923, Istanbul remains the nation's largest city with a population of over 8 million, its commercial center, and a major port. Two bridges spanning the Bosporus, and ships in the busy channel can be seen on the enlargement. On the image, the water areas have been replaced with a thermal image: colder waters are displayed in dark blue, warmer areas in light blue. Note the dark lines showing boat wakes, and the cold water entering the Sea of Marmara from deeper waters of the Bosporus.Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry.

  3. Hydrodynamic and sedimentological controls governing formation of fluvial levees

    2017-12-01

    Fluvial levees are familiar features found on the margins of river channels, yet we know little about what controls their presence, height, and shape. These attributes of levees are important because they control sediment transfer from channel to floodplain and flooding patterns along a river system. Despite the familiarity and importance of levees, there is a surprising lack of basic geomorphic data on fluvial levees. Because of this we seek to understand: 1) where along rivers do levees tend to occur?; 2) what geomorphic and hydrodynamic variables control cross-sectional shape of levees? We address these questions by extracting levee shape from LiDAR data and by collecting hydrodynamic and sedimentological data from reaches of the Tippecanoe River, the White River, and the Muscatatuck River, Indiana, USA. Fluvial levees are extracted from a 1.5-m resolution LiDAR bare surface model and compared to hydrological, sedimentological, and geomorphological data from USGS stream gages. We digitized banklines and extracted levee cross-sections to calculate levee slope, taper, height, e-folding length, and e-folding width. To answer the research questions, we performed a multivariable regression between the independent variables—channel geometry, sediment grain size and concentration, flooding conditions, and slope—and the dependent levee variables. We find considerable variation in levee presence and shape in our field data. On the Muscatatuck River levees occur on 30% of the banks compared to 10% on the White River. Moreover, levees on the Muscatatuck are on average 3 times wider than the White River. This is consistent with the observation that the Muscatatuck is finer-grained compared to the White River and points to sedimentology being an important control on levee geomorphology. Future work includes building a morphodynamic model to understand how different hydrodynamic and geomorphic conditions control levee geometry.

    2016-01-01

    Full Text Available The article deals with current issues of energy diplomacy of Turkey. The authors describe the main positive and negative results of Turkey's foreign energy policy in terms of the implementation of major energy projects. Geopolitical processes in the world, the conflict of interests of various countries in the political arena are important factors that affect the crude oil and natural gas pipeline projects. Particular attention is paid to the problems and prospects of cooperation between the Turkish Republic and the Russian Federation in the fuel and energy complex. The authors describe the interaction betweeen Russia and Turkey in the energy sector, including geo-economic interests of the countries in the Russian-Turkish gas dialogue. Turkey made efforts to position as an alternative gas supply route, taking advantage of concern about increasing Europe's dependence on Russian exports. Last years Turkey has set itself the important task - to turn from transit country into a regional gas hub. Ukrainian crisis increased the geostrategic importance of the Black Sea region to Russia, as well as strengthened the ambition of the Turkish side. The authors also highlight the prospects of the natural gas pipeline project from Russia via the Black Sea to Turkey and to the Turkish-Greek border, which named "Turkish stream". This project was frozen in terms of military and political processes at the end of 2015 in Syria.

    Because of its limited energy resources, Turkey is heavily dependent on imported oil and gas. 73 percent of the world's proven oil reserves and 72 percent of the world's proven gas reserves are located in the surrounding regions of Turkey: Middle East, Caspian Region and Russia. This makes Turkey a crucial bridge between energy rich regions and Europe. There are major oil and gas pipelines going through Turkey and additional pipelines are being constructed or are being planned. There is some production of lignite which is used in power plants and industry. Turkey's natural energy resources are quite diversified; with quite abundant coal reserves. Energy forecasts show that primary energy demand would be 117 million TOE in 2005 and 156 million TOE in 2010. Oil has the biggest share (39 percent) in total primary energy consumption, while natural gas has a share of 21 percent and increasing due to the recent diversification efforts of energy resources. Turkey has about 1percent of the total world hydroelectric potential and a considerable potential for electricity generation from wind. As of early 2004, Turkey had electric power generating capacity of around 32,000 megawatts (MW), and was building 13,000 MW more. Since adoption of Electricity Market Law in February 2001, there were significant changes towards liberalisation of power generation market and distribution in the country. Privatization of generation assets is envisaged to start in 2006. The Electricity Market Law set the stage for new supporting laws and regulations as well as new organization of the market: the Energy Market Regulation Agency (EMRA), that oversees the power, natural gas markets, oil markets and liquefied petroleum gases market, including setting tariffs, issuing licenses, and assuring competition; the Energy Market Regulatory Board, which runs the EMRA; the Energy Market Licensing Regulation and the Electricity Market Tariffs Regulation; 4-phase approach towards electric energy market

    Two flocks of 14,000 twenty-week-old turkey hens each experienced increased mortality due to hepatic lipidosis. Some hens showed signs of dyspnea and cyanosis before death. Necropsy revealed dark muscles and enlarged livers with pale areas and numerous hemorrhages. Petechial and ecchymotic hemorrhages were also found on the abdominal fat and epicardium. Lung congestion and edema were prominent. In the heart and blood vessels, the blood was uncoagulated. Mortality was elevated for 12 days and resulted in the death of 0.7% of the turkey hens in one flock and 1.7% in the other. Vitamin E administered in water at a dose of 25 IU per hen appeared to reduce mortality. The nutritional and environmental factors that may contribute to the development of hepatic lipidosis in turkeys are discussed.

  10. Sedimentological regimes for turbidity currents: Depth-averaged theory

    Science.gov (United States)

    Halsey, Thomas C.; Kumar, Amit; Perillo, Mauricio M.

    2017-07-01

    Turbidity currents are one of the most significant means by which sediment is moved from the continents into the deep ocean; their properties are interesting both as elements of the global sediment cycle and due to their role in contributing to the formation of deep water oil and gas reservoirs. One of the simplest models of the dynamics of turbidity current flow was introduced three decades ago, and is based on depth-averaging of the fluid mechanical equations governing the turbulent gravity-driven flow of relatively dilute turbidity currents. We examine the sedimentological regimes of a simplified version of this model, focusing on the role of the Richardson number Ri [dimensionless inertia] and Rouse number Ro [dimensionless sedimentation velocity] in determining whether a current is net depositional or net erosional. We find that for large Rouse numbers, the currents are strongly net depositional due to the disappearance of local equilibria between erosion and deposition. At lower Rouse numbers, the Richardson number also plays a role in determining the degree of erosion versus deposition. The currents become more erosive at lower values of the product Ro × Ri, due to the effect of clear water entrainment. At higher values of this product, the turbulence becomes insufficient to maintain the sediment in suspension, as first pointed out by Knapp and Bagnold. We speculate on the potential for two-layer solutions in this insufficiently turbulent regime, which would comprise substantial bedload flow with an overlying turbidity current.

    Confluences are key locations within large river networks, yet surprisingly little is known about how they migrate and evolve through time. Moreover, because confluence sites are associated with scour pools that are typically several times the mean channel depth, the deposits associated with such scours should have a high potential for preservation within the rock record. However, paradoxically, such scours are rarely observed, and the sedimentological characteristics of such deposits are poorly understood. This study reports results from a physically-based morphodynamic model, which is applied to simulate the evolution and resulting alluvial architecture associated with large river junctions. Boundary conditions within the model simulation are defined to approximate the junction of the Ganges and Jamuna rivers, in Bangladesh. Model results are supplemented by geophysical datasets collected during boat-based surveys at this junction. Simulated deposit characteristics and geophysical datasets are compared with three existing and contrasting conceptual models that have been proposed to represent the sedimentary architecture of confluence scours. Results illustrate that existing conceptual models may be overly simplistic, although elements of each of the three conceptual models are evident in the deposits generated by the numerical simulation. The latter are characterised by several distinct styles of sedimentary fill, which can be linked to particular morphodynamic behaviours. However, the preserved characteristics of simulated confluence deposits vary substantial according to the degree of reworking by channel migration. This may go some way towards explaining the confluence scour paradox; while abundant large scours might be expected in the rock record, they are rarely reported.

    The global energy requirement for sustaining economic activities, meeting social needs and social development is increasing daily. Environmentally friendly, renewable energy resources are an alternative to the primary non-renewable energy resources, which devastate ecosystems in order to meet increasing demand. Among renewable energy sources such as hydropower, biopower, geothermal power and solar power, wind power offers distinct advantages to Turkey. There is an increasing tendency toward wind globally and the European Union adjusted its legal regulations in this regard. As a potential EU Member state, Turkey is going through a similar process. The number of institutional and legal regulations concerning wind power has increased in recent years; technical infrastructure studies were completed, and some important steps were taken in this regard. This study examines the way in which Turkey has developed support for wind power, presents a SWOT analysis of the wind power sector in Turkey and a projection was made for the concrete success expected to be accomplished in the future.

    2005-01-01

    Most of the locations in Turkey receive abundant solar-energy, because Turkey lies in a sunny belt between 36 deg. and 42 deg. N latitudes. Average annual temperature is 18 to 20 deg. C on the south coast, falls to 14-16 deg. C on the west coat, and fluctuates between 4 and 18 deg. C in the central parts. The yearly average solar-radiation is 3.6 kW h/m 2 day, and the total yearly radiation period is ∼2610 h. In this study, a new formulation based on meteorological and geographical data was developed to determine the solar-energy potential in Turkey using artificial neural-networks (ANNs). Scaled conjugate gradient (SCG), Pola-Ribiere conjugate gradient (CGP), and Levenberg-Marquardt (LM) learning algorithms and logistic sigmoid (logsig) transfer function were used in the networks. Meteorological data for last four years (2000-2003) from 12 cities (Canakkale, Kars, Hakkari, Sakarya, Erzurum, Zonguldak, Balikesir, Artvin, Corum, Konya, Siirt, and Tekirdag) spread over Turkey were used in order to train the neural-network. Meteorological and geographical data (latitude, longitude, altitude, month, mean sunshine-duration, and mean temperature) are used in the input layer of the network. Solar-radiation is in the output layer. The maximum mean absolute percentage error was found to be less than 3.832% and R 2 values to be about 99.9738% for the selected stations. The ANN models show greater accuracy for evaluating solar-resource possibilities in regions where a network of monitoring stations has not been established in Turkey. This study confirms the ability of the ANN to predict solar-radiation values accurately

  18. Blueprint for a coupled model of sedimentology, hydrology, and hydrogeology in streambeds

    2017-06-01

    The streambed constitutes the physical interface between the surface and the subsurface of a stream. Across all spatial scales, the physical properties of the streambed control surface water-groundwater interactions. Continuous alteration of streambed properties such as topography or hydraulic conductivity occurs through erosion and sedimentation processes. Recent studies from the fields of ecology, hydrogeology, and sedimentology provide field evidence that sedimentological processes themselves can be heavily influenced by surface water-groundwater interactions, giving rise to complex feedback mechanisms between sedimentology, hydrology, and hydrogeology. More explicitly, surface water-groundwater exchanges play a significant role in the deposition of fine sediments, which in turn modify the hydraulic properties of the streambed. We explore these feedback mechanisms and critically review the extent of current interaction between the different disciplines. We identify opportunities to improve current modeling practices. For example, hydrogeological models treat the streambed as a static rather than a dynamic entity, while sedimentological models do not account for critical catchment processes such as surface water-groundwater exchange. We propose a blueprint for a new modeling framework that bridges the conceptual gaps between sedimentology, hydrogeology, and hydrology. Specifically, this blueprint (1) fully integrates surface-subsurface flows with erosion, transport, and deposition of sediments and (2) accounts for the dynamic changes in surface elevation and hydraulic conductivity of the streambed. Finally, we discuss the opportunities for new research within the coupled framework.

    Full Text Available From the early 1930s until his peace time premiership (1951-1955, Winston Churchill was one of the strongest advocates of the concept of a United Europe. While this is well known among scholars of 20th century British history, Churchill’s actual vision for what a United Europe might look like has received less attention. Still less attention has been paid to Churchill’s opinions of the roles other nations might play within the new Europe. This article will examine Churchill’s view of Turkey in the new European order and will reveal that Churchill saw Turkey as a part of, (or at least an extension of Europe. However, this article will also reveal that Churchill’s conceptualisation of Turkey’s role was largely predicated on 19th century geostrategic thinking.

    Full Text Available Water is one of our most critical resources. Civilization has historically flourished around major waterways. The most important uses of water are; agricultural, industrial and domestic use. This critical resource is under threat around the world. In the next 20 years, the quantity of water available to everyone is predicted to decrease by 30%. 40% of the world\\\\\\\\\\\\\\'s inhabitants currently have insufficient fresh water for minimal hygiene. In 2000 more than 2.2 million people died from waterborne diseases. Water politics is politics affected by water and water resources. There are connections between water resources, water systems, and international security and conflict. Today, water is a strategic resource in the globe and an important element in many political conflicts. Turkey can be faced severe water-stress in the near future. Therefore Turkey has to develop realistic and feasible water policy for future generations. [TAF Prev Med Bull 2011; 10(3.000: 327-338

    Turkey is a developing country with a population of 56 millions and approximately $ 2604 per capita income. Geographically she is located among the energy rich countries whereas almost half of her energy requirement is met by imports. Turkey is relatively well endowed with hydro-power and lignite resources, some limited amount of oil, gas and coal resources exist and there is significant geothermal potential in the country. Environmental issues are increasingly important consideration in energy policy decisions in the world. Energy production, transportation and use are contributing to environmental degradation to a certain extent. Protection of the environment and public health from pollution arising from energy production and consumption activities is one of the principles of Turkish national energy policy. In conjunction with this policy the 'Environment Law' was promulgated in 1983 and 'The Regulation on Protection of the Air Quality' in order to control all kinds of emissions in the form of soot, smoke, fines and particulate and to prevent the adverse impacts of the air pollution, was issued in October 1986. Policy of diversification of energy sources and the environmental issues which were explained above brought the natural gas usage into the energy scene in Turkey. 6 figs., 4 tabs

    Radioisotopes have two main uses in sedimentology: they are used for the study of sediment movements in rivers and seas, and for continuous measurements of the amount of sediment suspended in a given medium. These two uses are considered in detail, and brief accounts given of some other uses. Study of sediment movements. After describing the basic technique used in sediment movement studies (injection of a labelled sediment or a simulator into the current, followed by tracking the radioactivity), the author enumerates as fully as possible the problems that can be solved with the help of this technique. Essentially, these problems fall into two groups: 1. Problems related to civil engineering works in coastal areas: the siltation of harbour channels and docks, the formation of banks and bars, the choice of sites for disposing of dredged sediment, the siting of ports, coastline protection, etc. Problems associated with civil engineering works in and near rivers; siting of the water intakes of hydroelectric and nuclear power stations, the effects of construction work on the transport of solids, the construction of dams, the protection of river banks, the construction of jetties, the siltation of lakes, etc. Problems common to these include the transport of effluent and the calibration of hydraulic models. The bibliography is based mainly on fairly recent references and on current research work. 2. Problems related to basic or applied research conducted mainly by universities and research centres: the study of the Quarternary of a particular region, pure sedimentology, the investigation of major sediment transport currents, the confirmation or refutation of transport theories, research into fundamental transport phenomena associated with channel experiments. After referring to the possible exploitation of natural tracers (contained in radioactive waste and fallout), the author discusses the technical aspects of using artificial tracers: the choice of radioisotope

    There has been a long tradition in the Ottoman Empire and the Turkish Republic of receiving refugees. There were Jewish refugees from the Spanish Inquisition, Hungarians and Poles fleeing revolts in 1848-9, and those of Turkish descent and usually from the Balkans. Concurrent with this trend is the history of refugees and immigrants leaving Turkey, such as many Armenians, Greeks and Jews leaving at the turn of the century, and after 1923 and the Treaty of Lausanne. Little is currently published on the topic. This article defines a refugee; provides an overview of the refugee problems of the 1980's due to Bulgarian, Kurdish, and Turkish refugees; and the legal and political aspects. As a country of origin, there is discussion of the political and economic aspects of Turkish asylum seekers in Europe. The potential refugee flows to and from Turkey are also examined. I) For this study, refugees are victims of political violence and are persecuted for political or religious beliefs, ethnic or racial background, or war. In Turkey, there are national refugees, international refugees outside the Convention, and UNHCR Convention refugees. During the 1980's all 3 groups were arriving: from eastern Europe, Iranian Kurds, Iraqis, and ethnic Turks from Bulgaria and Afghanistan. The Turkish restricted acceptance of the 1951 Convention on Refugees creates serious humanitarian and security consequences for refugees other than those from eastern Europe and of Turkish ethnicity. Political considerations play an important role in treatment where security threats outweigh humanitarian need. The case is given for Kurdish refugees. II) Asylum seekers from Turkey in Western Europe was determined between 1986-90 to be 185,000 from applications. These figures have risen steadily due to the political instability and military activity of areas bordering Iraq and Syria, the Emergency Region. In addition there are economic and employment problems, and there has been a suspension of human

    The world's most expensive motor fuel (gasoline, diesel and LPG) is sold most likely in the Republic of Turkey. This paper investigates the key issues related to the motor fuel prices in Turkey. First of all, the paper analyses the main reason behind high prices, namely motor fuel taxes in Turkey. Then, it estimates the elasticity of motor fuel demand in Turkey using an econometric analysis. The findings indicate that motor fuel demand in Turkey is quite inelastic and, therefore, not responsive to price increases caused by an increase in either pre-tax prices or taxes. Therefore, fuel market in Turkey is open to opportunistic behavior by firms (through excessive profits) and the government (through excessive taxes). Besides, the paper focuses on the impact of high motor fuel prices on road transport associated activities, including the pattern of passenger transportation, motorization rate, fuel use, total kilometers traveled and CO 2 emissions from road transportation. The impact of motor fuel prices on income distribution in Turkey and Turkish public opinion about high motor fuel prices are also among the subjects investigated in the course of the study. - Highlights: • The key issues (e.g. taxes) related to motor fuel prices in Turkey are explored. • Their impact on transport activities and income distribution is also investigated. • An econometric analysis is performed to estimate motor fuel demand in Turkey. • Motor fuel demand in Turkey is found to be quite inelastic. • Turkish fuel market is open to opportunistic behavior by firms and the government

    Nuclear Medicine is a medical specialty that uses radionuclides for the diagnosis and treatment of diseases and it is one of the most important peaceful applications of nuclear sciences. Nuclear Medicine has a short history both in Turkey and in the world. The first use of I-131 for the treatment of thyrotoxicosis in Turkey was in 1958 at the Istanbul University Cerrahpasa Medical School. In 1962, Radiobiological Institute in Ankara University Medical School was established equipped with well-type counters, radiometers, scalers, external counters and a rectilinear scanner. In 1965, multi-probe external detection systems, color dot scanners and in 1967, anger scintillation camera had arrived. In 1962, wet lab procedures and organ scanning, in 1965 color dot scanning, dynamic studies (blood flow - renograms) and in 1967 analogue scintillation camera and dynamic camera studies have started. In 1974, nuclear medicine was established as independent medical specialty. Nuclear medicine departments have started to get established in 1978. In 1974, The Turkish Society of Nuclear Medicine (TSNM) was established with 10 members. The first president of TSNM was Prof. Dr. Yavuz Renda. Now, in the year 2000, TSNM has 349 members. Turkish Society of Nuclear Medicine is a member of European Association of Nuclear Medicine (EANM), World Federation of Nuclear Medicine and Biology (WFNMB) and WFNMB Asia-Oceania. Since 1974, TSNM has organized 13 national Nuclear Medicine congresses, 4 international Nuclear Oncology congresses and 13 nuclear medicine symposiums. In 1-5 October 2000, 'The VII th Asia and Oceania Congress of Nuclear Medicine and Biology' was held in Istanbul, Turkey. Since 1992, Turkish Journal of Nuclear Medicine is published quarterly and it is the official publication of TSNM. There are a total of 112 Nuclear Medicine centers in Turkey.

    forming the town wall between Porta Sirena and Porta Giustizia (southern-eastern side of Paestum) and in the civil and sacred architecture. The time-space relationships among the above lithofacies associations clearly emerge in the Porta Marina area both in the Greek walls of the ancient town (slope and swamp facies) and in the outcropping travertine substrate (slope and waterfall deposits). Based on the above sedimentological results, it may be inferred that, like other ambient temperature travertine systems studied in southern Italy, the Paestum travertine growth developed over a gentle slope surface (in our case dipping to the west), laterally evolving into rapid and waterfall deposits. At the same time, the aggradational growth of the travertine system resulted in a flattened summit area with widespread swamp and marsh environments. The ruins of Paestum, including the lower parts of sacred and civil buildings as well as town roads and walls, are even today largely covered by recent semi-coherent travertines (tufa), originating from waters that encrusted and then "fossilized" a large part of the town. Inside the town walls, these materials were pedogenized and nowadays are largely cultivated around and within the archeological area. A portion of these deposits was removed during the excavations of the beginning of last century, but traces of them may still be observed in different parts of the ancient town. Like the foundation travertines, the recent deposits are mainly made up of calcareous encrustations. Gastropods, ostracods and other organisms typical of terrestrial humid environments may be found in the phytoclastic textures. Usually, they are weakly cemented and at places incorporate different materials, including brick, wood and coal fragments. These sediments patchy cover the town within the wall perimeter, for a few decimetres in the sacred areas, but reaching over 4 meters downhill and outside the walls: a process of "fossilization" that appears to have been

Five year later World Health Organization (WHO declared the six effective approach for tobacco control, under the name of MPOWER. In the following years, WHO evaluated the level of implementation of MPOWER criteria in the countries. In this article, how Turkey implemented these six criteria will be discussed. Monitor tobacco use and prevention policies: Monitoring of tobacco use prevalence has been successfully monitored in Turkey through Global Adult Tobacco Survey, Global Youth Tobacco Survey and Health Professionals Tobacco Use Survey. Nevertheless, monitoring of tobacco industry activities was not successfully implemented. Protect people from tobacco smoke: Smoking was banned in most of the indoor public places in Turkey since 1996, and Turkey became a complete smoke-free country by the exposion of smoke-free places including the hospitality workplaces in 2008. Offer help to quit tobacco use: Although smoking cessation services has been a bit late in Turkey, availability of smoking cessation drugs and the establishment of free quitline services made Turkey successful in this regard. Warn about the dangers of tobacco: Since 1996, all TV channels have a duty of broadcasting programs on harms of tobacco use, not less than 90 minutes in a month and it has been implemented successfully. Additionally written messages indicating harms of tobacco has been printed on the packs since 1988 and pictures was added in 2010. But since the average surface area covered by the messages in less than 50% of the total surface of the pack, Turkey was not regarded as to meet the requirement. Enforce bans on tobacco advertising, promotion and sponsorship: All kinds of tobacco advertisement and promotion was banned by the Law in 1996. But the tobacco products was not in closed boxes at the sales points. Turkey was not found as successful

    1982-08-01

    As part of its research program, NUCOR carried out a sedimentological investigation of the Banksgaten uranium deposit discovered by Esso Minerals. The Banksgaten prospect is situated on a promontory of the Nuweveld Escarpment, 35 km south-east of Sutherland. The six prominent sandstone units exposed in the study area form part of the arenaceous Oukloof Member of the Teekloof Formation. Palaeocurrent studies show a wide variation in transport direction. However, the vector mean palaeocurrent trend is towards the north-north-east. The sedimentological environment is a distal braided river forming part of a deltaic plain. The uranium mineralisation occurs on three stratigraphic levels and is concentrated almost exclusively in the channels of the different sandstones. These channels are vertically superimposed and probably inherited the drainage pattern of pre-existing channels

    The radiocarbon dating of sediments using marine shells involves uncertainties due to the mixed ages of the shells mainly attributed to depositional processes also known as 'sedimentological time-averaging'. This stratigraphic disorder can be removed by selecting the well-preserved indigenous shells based on ecological and taphonomic criteria. These criteria on sample selection are recommended for accurate estimation of the depositional age of geologic strata from 14 C dating of marine shells

    A new gamma-backscattering sedimentological gauge has been designed to measure the high concentrations of suspended sediments of rivers in a stationary position for different depths at flooding times continuously for 9 hours. The instrument is capable of measuring concentrations from 5 to 95 g/l with a good accuracy and of higher concentrations as well. In comparison to common instruments based on gamma radiation absorption this one classifies for higher concentrations. (orig.) [de

    In a companion work, we bridge the gap between mature segmentation software used in terrestrial sedimentology and emergent planetary segmentation with an original algorithm optimized to segment whole images from the Microscopic Imager (MI) of the Mars Exploration Rovers (MER). In this work, we compare its semi-automated outcome with manual photoanalyses using unconsolidated sediment at Gusev and Meridiani Planum sites for geologic context. On average, our code and manual segmentation converge to within ∼10% in the number and total area of identified grains in a pseudo-random, single blind comparison of 50 samples. Unlike manual segmentation, it also locates finer grains in an image with internal consistency, enabling robust comparisons across geologic contexts. When implemented in Mathematica-8, the algorithm segments an entire MI image within minutes, surpassing the extent and speed possible with manual segmentation by about a factor of ten. These results indicate that our algorithm enables not only new sedimentological insight from the MER MI data, but also detailed sedimentology with the Mars Science Laboratory’s Mars Hand Lens Instrument.

    Heterolithic or 'shaly' sandstone reservoirs constitute a significant proportion of hydrocarbon resources. Petroacoustic models (a combination of petrophysics and rock physics) enhance the ability to extract reservoir properties from seismic data, providing a connection between seismic and fine-scale rock properties. By incorporating sedimentological observations these models can be better constrained and improved. Petroacoustic modelling is complicated by the unpredictable effects of clay minerals and clay-sized particles on geophysical properties. Such effects are responsible for erroneous results when models developed for "clean" reservoirs - such as Gassmann's equation (Gassmann, 1951) - are applied to heterolithic sandstone reservoirs. Gassmann's equation is arguably the most popular petroacoustic modelling technique in the hydrocarbon industry and is used to model elastic effects of changing reservoir fluid saturations. Successful implementation of Gassmann's equation requires well-constrained drained rock frame properties, which in heterolithic sandstones are heavily influenced by reservoir sedimentology, particularly clay distribution. The prevalent approach to categorising clay distribution is based on the Thomas - Stieber model (Thomas & Stieber, 1975), this approach is inconsistent with current understanding of 'shaly sand' sedimentology and omits properties such as sorting and grain size. The novel approach presented here demonstrates that characterising reservoir sedimentology constitutes an important modelling phase. As well as incorporating sedimentological constraints, this novel approach also aims to improve drained frame moduli estimates through more careful consideration of Gassmann's model assumptions and limitations. A key assumption of Gassmann's equation is a pore space in total communication with movable fluids. This assumption is often violated by conventional applications in heterolithic sandstone reservoirs where effective porosity, which

    Quality health care is an issue of concern worldwide, and nursing can and must play a major and global role in transforming the healthcare environment. Doctorally prepared nurses are very much needed in the discipline to further develop and expand the science, as well as to prepare its future educators, scholars, leaders, and policy makers. In 1968, the Master of Science in Nursing Program was initiated in Turkey, followed by the Nursing Doctoral Education Program in 1972. Six University Schools of Nursing provide nursing doctoral education. By the graduating year of 2001, 154 students had graduated with the Doctor of Philosophy in Nursing (Ph.D.), and 206 students were enrolled in related courses. Many countries in the world are systematically building various collaborative models in their nursing doctoral education programs. Turkey would like to play an active role in creating collaborative nursing doctoral education programs with other countries. This paper centres on the structure and model of doctoral education for nurses in Turkey. It touches on doctoral programs around the world; describes in detail nursing doctoral education in Turkey, including its program structure, admission process, course units, assessment strategies and dissertation procedure; and discusses efforts to promote Turkey as a potential partner in international initiatives to improve nursing doctoral education.

    The main goal of this study is to develop the equations for forecasting net energy consumption (NEC) using an artificial neural-network (ANN) technique in order to determine the future level of energy consumption in Turkey. In this study, two different models were used in order to train the neural network. In one of them, population, gross generation, installed capacity and years are used in the input layer of the network (Model 1). Other energy sources are used in input layer of network (Model 2). The net energy consumption is in the output layer for two models. Data from 1975 to 2003 are used for the training. Three years (1981, 1994 and 2003) are used only as test data to confirm this method. The statistical coefficients of multiple determinations (R 2 -value) for training data are equal to 0.99944 and 0.99913 for Models 1 and 2, respectively. Similarly, R 2 values for testing data are equal to 0.997386 and 0.999558 for Models 1 and 2, respectively. According to the results, the net energy consumption using the ANN technique has been predicted with acceptable accuracy. Apart from reducing the whole time required, with the ANN approach, it is possible to find solutions that make energy applications more viable and thus more attractive to potential users. It is also expected that this study will be helpful in developing highly applicable energy policies

    Goda Buticha is a cave site near Dire Dawa in southeastern Ethiopia that contains an archaeological sequence sampling the late Pleistocene and Holocene of the region. The sedimentary sequence displays complex cultural, chronological and sedimentological histories that seem incongruent with one another. A first set of radiocarbon ages suggested a long sedimentological gap from the end of Marine Isotopic Stage (MIS) 3 to the mid-Holocene. Macroscopic observations suggest that the main sedimentological change does not coincide with the chronostratigraphic hiatus. The cultural sequence shows technological continuity with a late persistence of artifacts that are usually attributed to the Middle Stone Age into the younger parts of the stratigraphic sequence, yet become increasingly associated with lithic artifacts typically related to the Later Stone Age. While not a unique case, this combination of features is unusual in the Horn of Africa. In order to evaluate the possible implications of these observations, sedimentological analyses combined with optically stimulated luminescence (OSL) were conducted. The OSL data now extend the radiocarbon chronology up to 63 ± 7 ka; they also confirm the existence of the chronological gap between 24.8 ± 2.6 ka and 7.5 ± 0.3 ka. The sedimentological analyses suggest that the origin and mode of deposition were largely similar throughout the whole sequence, although the anthropic and faunal activities increased in the younger levels. Regional climatic records are used to support the sedimentological observations and interpretations. We discuss the implications of the sedimentological and dating analyses for understanding cultural processes in the region. PMID:28125597

    The quality and the quantity of organic carbon preserved in modern and ancient terrestrial sediments is the result of a complex interactions of sedimentological factors, such as in-situ productivity, allochtonous supply of organic matter, oxidation processes, biodegradation and sediment accumulation rates. The study aims at utilizing multidisciplinary information in order to characterize the palaeoenvironment in Westphalian fluvio-lacustrine deposits of the Lorraine Coal Basin (NE France). In this basin, the lack of outcrops is the major difficulty. To compensate for this problem, sedimentology, and molecular geochemistry are combined in order to significantly improve the palaeoenvironmental assessment of the area. Geochemical analyses and sedimentology have been carried out on several core samples of the Saulcy drill hole to evaluate local palaeoenvironmental variability. The lithofacies associations in the Upper Carboniferous of the Lorraine basin suggest an alluvial plain environment without marine incursions. Sedimentological interpretations of the core, as well as comparison with sedimentological models, suggests the recognition of different depositional environments from braided and/or meandering rivers to swamp and lakes. The organic geochemistry is focussed on the recognition of aliphatic hydrocarbons and especially on molecular biomarkers, which provide valuable information about the original organic matter and the transformations that took place during sedimentation and diagenesis. In the Lorraine basin, the botanical variability is high and clearly related to the position of the vegetation communities in the fluvial system. The biomarkers (e.g., diterpanes, steranes) show variations, which can be related to the diversity of this ecosystem. In this study, a reinterpretation of the environmental zonation in the sterane ternary diagram adapted to a fluvio-lacustrine sedimentology is proposed. The correlation between sedimentological and geochemical

    Turkey Vultures (Cathartes aura), were surveyed monthly in Cuba from March 1982-January 1983. A total of 25371 vultures were tallied in 7186 km (3.5 vultures/transect km) of roadside counting along main highways leading from the city of La Habana (northwestern Cuba) to the city of Las Tunas (southeast). Numbers of vultures counted declined substantially beyond 200 m from the transect road. Density of vultures observed within 200 m of the road along the transect route was 0.06/ha. Highest counts were obtained in March, April and June. Turkey Vulture flying activity was greatest during the periods 0900-1200 H and 1400-1700 H.

  12. Labour migration from Turkey.

    This study is concerned with Turkish labor migration to Western Europe. Earlier and recent patterns of labor migration, characteristics of migrants by occupation, area of destination, and by geographical origins are discussed. Economic and demographic consequences of labor migration are also analyzed. It is estimated that Turkey's population will reach 73 million at the year 2000 with the present growth rate of 2.48% annually. Considering the efforts made to slow down the present high fertility rates and assuming that the decrease in labor force participation during 1970-1980 continues, the author concludes that the labor supply will increase with a growth rate of 2% annually for the next 13-15 years. Thus, the labor supply will reach 26.6 million people in the year 2000 from the 1980 level of 17.8 million. Assuming also that the income/employment elasticity of .25 which was observed throughout the period of 1960-1980 will not change until 2000, the annual growth rate of employment may be estimated as 1.5%. Thus, the number of people employed will reach 20 million in the year 1990 and 23.2 million in the year 2000. 8.8 million people will join the labor market as new entrants between 1980 and 2000. Only 6 million people out of 8.8 million will be employed. Thus, in the year 2000, it is estimated that 2.8 million new unemployed people will be added to the already open unemployment figure 1980 census data give the number of unemployed as .6 million people. Adding the 2.8 million new unemployed to this figure totals 3.4 million unemployed in 2000. The State Planning Organization's estimate of labor surplus for 1980 was 2.5 million people. When 2.8 million unemployed people are added to this figure, the labor surplus for the year 2000 reaches 5.3 million people.

    We are at the beginning of a new millennium. At this stage, we are observing economic and social liberalization efforts and regional alliance projects throughout the world. In this very same process, we are also experiencing a more holistic concept called globalization, which covers rapid and simultaneous dissemination and integration of capital, labor, information and technology, world-wide. This globalization opened a new era where national market economies and local companies went into competition in the international arena. In this era, it became a necessity for the non-liberal economies to catch up with the developments in the international markets and be open to economic and political changes. These developments have brought along many radical economic and social changes throughout the world. Policies adopted in Turkey, with respect to the energy reform process, display a general tendency towards putting in place a legal framework that will support the implementation of good governance principles, and providing conformity with the relevant legislative infrastructure of both OECD and EU countries. Turkey has only limited reserves of oil and natural gas, but substantial reserves of coal, particularly lignite. Energy demand has grown at 4-5 % per annum over the past three decades and will continue to grow rapidly, which will require enormous investments in 2000 and 2020, with the most significant increase being that of natural gas. Because of its limited energy resources, Turkey is heavily dependent on imported oil and gas. There are major oil and gas pipelines going through Turkey and additional pipelines are being constructed or are being planned. There is some production of lignite which is used in power plants and industry. 73 % of the world's proven oil reserves and 72 % of the world's proven gas reserves are located in the surrounding regions of Turkey: Middle East, Caspian Region and Russia. This makes Turkey a crucial bridge between energy rich regions

    We present preliminary micropaleontological and sedimentological data from IODP Site U1390 (Expedition 339), located in the central middle slope of the Gulf of Cadiz, since the last glaciation. This site has been targeted for reconstruction of regional paleo-circulation as it shows particularly high sedimentation rates, throughout the Holocene and the Last Glacial Maximum (LGM). We use micropaleontological and sedimentological proxies to understand the bottom current variations through time and the ecological conditions at the sea surface (planktonic foraminifer, pteropod and nannofossil assemblages), and the sea bottom (ostracod assemblages). Eleven samples, chosen at transitions of planktonic foraminifer assemblages, have been dated by AMS radiocarbon analyses. Preliminary results from benthic ostracod assemblages show variations in bottom water ventilation and food supply. Planktonic foraminifer assemblages clearly show the well-known cold events of this period such as the Younger Dryas and Heinrich stadial associated to coarser sediment, and warmer phases such as the Bölling-Allerød associated to muddy sediment. Other bio-events within the Holocene period are also recorded. The preservation of the coccolithophore assemblages is good to moderate. Coccolith abundances (expressed in coccoliths/gr of sediment) show higher values during the Holocene and generally are like assemblages previously reported for the same area. Implications for characterization of the Holocene, the last termination and LGM ecological conditions at high resolution and their potential fluctuations (i.e. amplitude and magnitude) under the influence of the lower core of the Mediterranean Outflow Water (MOW), with this multi proxy approach based on sedimentological, and paleontological data will be discussed.

    There is a lack of information regarding marine radioactivity in sediments of the Continental Margin of the South Atlantic. "1"3"7Cs and "4"0K radioactivity and sedimentological variables were determined in superficial sediment samples. It was demonstrated that "4"0K is a good indicator for sediment granulometry, whilst "1"3"7Cs presents a good correlation with its chemical composition. Moreover, it was identified through the radiometric data the occurrence of input of allochtonous matter to the Brazilian southernmost compartment from the Rio de La Plata estuary, as previously reported in the literature.

    A sedimentological and mineralogical study of sedimentary cores allowed reconstructing the evolution of depositional environments along the Northern coast of Sfax (Tunisia). The aim of this research work is to identify the factors controlling the sedimentation from the Holocene to the Present time. Three 30-m sediment cores collected by drilling at 30 m water depth were analyzed for their color, magnetic susceptibility signal, grain size by laser diffraction, organic matter content by loss of ignition, carbonate content by calcimetry and mineralogy by X-ray diffraction on bulk powder and clay <2 μm. They broadly present the same sedimentological and mineralogical features. Microscopical observations of petrographic slides allowed identifying six main sedimentary facies. Bulk mineralogical assemblages comprised clay minerals, quartz, calcite, gypsum and K-feldspars were examined. Considerable change was observed in the carbonate content that mimicked the bioclaste abundance and diluted the detrital minerals (clay minerals, quartz and feldspars). The gypsum mainly occurred in the lower sedimentary columns (SC12 and SC9) and in the upper/middle of core SC6. The clay fraction was made of a mixture of kaolinite, illite, smectite and palygorskite with no clear variation through core depth. Both grain-size parameters and magnetic susceptibility profile showed a sharp transition in the upper 2-5 m of the sedimentological columns. Coarse, sandy to gravely sediments characterized by a low magnetic susceptibility signal were replaced by fine bioclastic-rich clayey sediments. The analysis of vertical succession of depositional facies revealed a fluvial depositional environment (coastal plain) basically marked by fluvial channels and inundation plains at the bottom of all cores. However, core-top sediments recorded a littoral marine environment with sand depositions rich in gastropods, lamellibranches and algæ. Depositional facies, sedimentological and mineralogical

In this report, multivariate analysis methods have been employed to study the relationships between the activities of the radionuclides and some sedimentological variables like granulometric facies, organic content and apparent density. The correlation functions found show that it is possible to determine, with a satisfactory degree of approximation, the granulometric facies of the sediments using only radiometric information

    Thalassemias and hemoglobinopathies are a serious health problem in Turkey. There is a 70-year history of thalassemia in Turkey. The first patient with β-thalassemia major (β-TM) was reported in 1941. The first clinical and hematological studies were published by Aksoy in 1958. The overall incidence of β-thalassemia (β-thal) was reported by Çavdar and Arcasoy to be 2.1% in 1971. Important steps such as written regulations, education and prevention campaigns, have been taken to prevent thalassemia in Turkey by the Ministry of Health (MOH), the Turkish National Hemoglobinopathy Council (TNHC) and the Thalassemia Federation of Turkey (TFT) since 2000. A national hemoglobinopathy prevention program was started in provinces with a high prevalence by the MOH in 2003. While the percentage of premarital screening test was 30.0% of all couples in 2003, it reached 86.0% in 2013. While the number of newborn with thalassemias and hemoglobinopathies was 272 in 2002, it had dropped to 25 in 2010. There has been a 90.0% reduction of affected births in the last 10 years.

    This study was conducted to reexamine the hypothesis that human metapneumovirus (hMPV) will not infect turkeys. Six groups of 2-week-old turkeys (20 per group) were inoculated oculonasally with 1 of the following: noninfected cell suspension; hMPV genotype A1, A2, B1, or B2; or avian metapneumovirus (aMPV) subtype C. Poults inoculated with hMPV showed nasal discharge days 4–9 postexposure. Specific viral RNA and antigen were detected by reverse-transcription PCR and immunohistochemical evaluation, respectively, in nasal turbinates of birds exposed to hMPV. Nasal turbinates of hMPV-infected turkeys showed inflammatory changes and mucus accumulation. Each of the 4 hMPV genotypes caused a transient infection in turkeys as evidenced by clinical signs, detection of hMPV in turbinates, and histopathologic examination. Detailed investigation of cross-species pathogenicity of hMPV and aMPV and its importance for human and animal health is needed. PMID:17235379

    2013-01-15

    The purpose of this report is to provide information about electric vehicles (EVs) and e-mobility as an emerging market in Turkey. EVs receive attention from the Turkish government for a number of reasons: Turkey has a strong automotive industry and needs to follow the technological developments taking place regarding intelligent vehicles and intelligent transport systems, as well as electric transportation technologies. Secondly, a considerable amount of carbon emissions from motor vehicles is of great concern in relation to climate change. EVs might be an alternative which can break the dependence of Turkey on imported fuel that has a negative influence on its current account deficit (CAD). On top of these factors, the Prime Minister of Turkey has a desire to have a 'Local Brand Vehicle' before the 100th year of the establishment of the Republic in 2023 and preferably an 'EV'. EVs are included in the strategy documents and action plans of almost all ministries and public institutions. Among all ministries, the Ministry of Science, Industry and Technology (MoSI and T) takes a leading position. It holds bi-annual meetings with stakeholders to monitor and evaluate progress about the level of actualization of the identified policies on e-mobility. MoSI and T's related institution of the Scientific and Technological Research Council of Turkey (TUBITAK) co-ordinates the R and D activities and provides generous R and D incentives. EVs have been put on sale in Turkey in 2012 and are still very limited in number. Public institutions are taking the lead by converting their vehicle fleet to EVs. EVs are also more suitable for businesses/ duties with a fixed/short route; therefore it is expected that the growth of the sector will mainly come from the vehicle fleet of the public organisations and institutions, followed by the private vehicle fleet of companies, e.g. freight companies. Although there are some on-going test drives, it is not yet proven

    The first microscopic sedimentological studies of the Martian surface will commence with the landing of the Mars Polar Lander (MPL) December 3, 1999. The Robotic Arm Camera (RAC) has a resolution of 25 um/p which will permit detailed micromorphological analysis of surface and subsurface materials. The Robotic Ann will be able to dig up to 50 cm below the surface. The walls of the trench will also be inspected by RAC to look for evidence of stratigraphic and / or sedimentological relationships. The 2001 Mars Lander will build upon and expand the sedimentological research begun by the RAC on MPL. This will be accomplished by: (1) Macroscopic (dm to cm): Descent Imager, Pancam, RAC; (2) Microscopic (mm to um RAC, MECA Optical Microscope (Figure 2), AFM This paper will focus on investigations that can be conducted by the RAC and MECA Optical Microscope.

    Full text: Turkey is a country with dynamic economic development and rapid population growth and nuclear energy is an integral part of these dynamics. Turkish Atomic Energy Authority (TAEA) is in charge of regulation and control of all activities related to nuclear field, including safety inspections and licensing. The TAEA is also responsible for the sensitive task of improving public awareness of nuclear technology which includes the use of nuclear power. Turkey's experience with nuclear power dates back to the 1960's, as the first nuclear research reactor started to operate in Istanbul in 1962. There were various plans for the introduction of nuclear power to the country. However the plans for the construction of the first nuclear power in the country were postponed for an indefinite period in 2000. In the wake of this decision TAEA initiated the activities to establish a nuclear policy in the country which includes creating the technical know-how and establishing new generation nuclear power plants in Turkey. The Authority is also responsible for the safe use of nuclear energy in medicine, agriculture, animal health, industry, food irradiation and in all kinds of research activities. The authority has carried or is currently continuing 12 National Technical Cooperation, 30 Research Contract, 21 Regional Europe ongoing IAEA projects and 31 State Planning Organization projects. There were 7571 radiological, 208 radiotherapy, 3792 industrial and 214 instruments licensed and registered by the Radiation Health and Safety Department of the Authority. We are in the opinion that developing a nuclear technology substructure in both Turkey and Turkish Countries will be of great benefit for the Euro-Asia region. We must emphasize that Turkey is the partner of all nonproliferation treaties and has no intention of using nuclear power for non peaceful purposes whatsoever

  10. Sedimentology and paleoecology of an Eocene Oligocene alluvial lacustrine arid system, Southern Mexico

    A depositional model of the Eocene-Oligocene Coatzingo Formation in Tepexi de Rodríguez (Puebla, Mexico) is proposed, based on facies analysis of one of the best-preserved sections, the Axamilpa Section. The sedimentary evolution is interpreted as the retrogradation of an alluvial system, followed by the progressive expansion of an alkaline lake system, with deltaic, palustrine, and evaporitic environments. The analysis suggests a change towards more arid conditions with time. Fossils from this region, such as fossil tracks of artiodactyls, aquatic birds and cat-like mammals, suggest that these animals traversed the area, ostracods populated the lake waters, and plants grew on incipient soils and riparian environments many times throughout the history of the basin. The inferred habitat for some fossil plants coincides with the sedimentological interpretation of an arid to semiarid climate for that epoch. This combined sedimentological-paleontological study of the Axamilpa Section provides an environmental context in which fossils can be placed and brings into attention important biotic episodes, like bird and camelid migrations or the origin of endemic but extinct plants in this area.

  11. The sedimentology and uranium mineralisation of the Matjieskloof (GT7) deposit, Fraserburg district

    Le Roux, J.P.

    1982-08-01

    A sedimentological investigation was carried out on the Matjieskloof prospect of JCI, 40 km south of Fraserburg at the foot of the Teekloof pass. The deposit is located in a thick, tabular sandstone forming part of the Poortjie Member at the base of the Teekloof Formation. A study of sedimentary structures, grain sizes and palaeocurrents in the sandstone sequence at Matjieskloof suggests a general decrease in energy conditions upward in the succession, indicating denudation of the source areas to the south-west. The depositional environment of the mineralised S1-sandstone as revealed by field work and borehole analysis, is that of a low-sinuosity, braided river of the Bijou Creek type, deposited during ephemeral flash floods in a semi-arid environment. Three main flow systems are revealed by the palaeocurrent analysis, showing good correspondence with the reconstructed palaeoriver system. In the areas where these flow systems cross, scouring of the S2-sandstone into the underlying S1-sandstone occured. These regions also correspond to the confluence areas of channels within the braided river system, and apparently formed favourable environments for uranium mineralisation. This may be due to the presence of erosion surfaces within these areas, the increased thickness of sandstones and the accumulation of plant material, controlled by current velocities. Molybdenum shows a similar distribution to the uranium mineralisation, and both are clearly controlled by the sedimentological sub-environments

    2001-08-01

    The sedimentary rocks of the Karoo Supergroup in the Tuli Basin (South Africa) may be grouped in four stratigraphic units: the basal, middle and upper units, and the Clarens Formation. This paper presents the findings of the sedimentological investigation of the fluvial terrigenous clastic and chemical deposits of the upper unit. Evidence provided by primary sedimentary structures, palaeontological record, borehole data, palaeo-flow measurements and stratigraphic relations resulted in the palaeo-environmental reconstruction of the upper unit. The dominant facies assemblages are represented by sandstones and finer-grained sediments, which both can be interbedded with subordinate intraformational coarser facies. The facies assemblages of the upper unit are interpreted as deposits of a low-sinuosity, ephemeral stream system with calcretes and silcretes in the dinosaur-inhabited overbank area. During the deposition of the upper unit, the climate was semi-arid with sparse precipitation resulting in high-magnitude, low-frequency devastating flash floods. The current indicators of the palaeo-drainage system suggest flow direction from northwest to southeast, in a dominantly extensional tectonic setting. Based on sedimentologic and biostratigraphic evidence, the upper unit of the Tuli Basin correlates to the Elliot Formation in the main Karoo Basin to the south.

    1956-01-01

    This thesis is divided in two parts: a detailed petrographical and stratigraphical study of the upper layers of calcareous schist in Congo which lead to some sedimentological considerations, and a metallogenic study of the ores of Niari basin which lead to a theoretical description of the metallogeny in Congo. In the first part, after a brief description of the methods used, a petrographical survey of the rocks of the upper layers of calcareous schist of the Boko-Congo area is given as well as sedimentological conclusions and stratigraphical data. The studies and conclusions related to this limited area are extended to a region scale. A structural study and precised descriptions of this region lead to an attempt of tectonic explanation. In the second part, an inventory and description of known mineralisation points in the Niari basin are given and in particular the detailed descriptions of four deposits: La Grande-Mine, M'Passa, Diangala and Djenguile. The interpretations and conclusions are based on the study of the general characters of the mineralisation in Niari basin and its comparison with the mineralisation in Katanga (now Shaba region) and North Rhodesia (now Zambia).

    Coverage of Turkey's vital registration system remains incomplete, and it cannot yet be used to measure annual population changes. Data and demographic indices based on the 1990 census and the 1989 National Demographic Survey are the most recent available. Turkey's population in 1990 was 56 million. The proportion urban increased to 59% from 49.2% in 1980. Nearly 35% of the population was under 15 years old, and the median age was 21.6 for males and 22.3 for females. The average age at first marriage in 1989 was 24.8 for men and 21.8 for women. Mortality has been in continuous decline. The crude death rate dropped from 16.4/1000 in 1960-65 to slightly under 8 in 1989. Life expectancy at birth was 63.3 for men and 66 for women. The infant mortality rate declined from 166 in 1965-70 to 85 in 1989. Rural or urban residence and maternal educational level were the most significant determinants of infant mortality differentials. Turkey's total fertility rate declined from 6.2 in 1960 to 4.3 in 1978 and 3.4 in 1988-89. The crude birth rate declined from around 40/1000 in 1968 to under 28/1000 in 1989. Fertility began to decline in the last third of the nineteenth century in Istanbul and other large cities of the Ottoman Empire. Istanbul's total fertility rate was a relatively low 3.9 even before World War I. Turkey adopted a policy to slow demographic growth in the mid 1960s, and family planning activities were supported by nongovernmental organizations. The direct impact of these policies on demographic behavior appears to have been somewhat limited, and the use of traditional methods of birth limitation remains widespread. Abortion was legalized in 1983 and is available at public hospitals. The proportion of married women aged 15-49 who use contraception increased from 38% in 1973 to 63% in 1988. Regional differentials in demographic indices are significant in Turkey, with the Anatolian East and Southeast lagging behind other regions in fertility and mortality decline

    Utilization of renewable energy sources and the application of environmentally sound energy technologies are essential to sustainable development and will help to secure the quality of living and the well-being of the future generations. Turkey presently has considerable renewable energy sources. The most important renewable sources are hydropower, wind, solar, geothermal, and biomass. The use of renewable energy as a topic to study energy and its forms permits a novel way to motivate students, particularly those who energy topics taking conscience with the environment. This paper presents the analysis and classification of renewable energy sources and how to find out their origin and a way to motivate students in energy topics related to renewable sources and also, the development of didactic competencies in special blended learning arrangements for educationalists, trainers and lecturers in adult education in the field of renewable energies in Turkey.

    1994-01-01

    In Turkey, the majority of the population live in rural areas where they use wild plants as food and medicine. The confusion of an edible plant with a poisonous one give rise to serious poisoning which may even result in death. The incidence of plant poisoning in Turkey is about 6% and especially high among children between ages of 2 and 11 living in rural areas. The number of species that cause poisoning is around twenty and Hyoscyamus niger (Solanaceae), Colchicum species (Liliaceae), Conium maculatum (Umbelliferae) and Prunus species (Rosaceae) are the most important. Mushroom poisoning is more frequent in spring and fall. The main reasons are their widespread usage as food and the inexperience of the gatherers in distinguishing the edibles from the poisonous. Amanita phalloides, A. verna, A. muscaria, A. pantherina are responsible for severe cases of poisoning.

    Full Text Available Turkey, which is among the major gene centers of the world and has a special place in plant genetic diversity. However, many plant genetic resources, including geophytes, are under genetic erosion because of the environmental and other problems and therefore face with the danger of extinction. Lilium ciliatum is endemic to North East Anatolia. IUCN (International Union for the Conservation of Natural Resources Red List Category of this species is Endangered (EN. Lilium ciliatum naturally grown in Zigana pass, Bayburt, Trabzon, Bulancak, Giresun and Gümüşhane is endangered and major threats of L. ciliatum are road construction and human disturbance related to ecotourism and recreation. It was reported that Lilium carniolicum naturally grown in Turkey is endangered although it isn’t in the IUCN Red List. Distribution areas of L. carniolicum are Trabzon, Rize, Artvin and it is also endemic to North East Anatolia. These species have high potential for use as ornamental plants with their colorful big flowers. In addition, the bulbs of these species are also used in the cosmetic industry and medicine. These are the main properties that increase the importance of L. ciliatum and L. carniolicum species. Therefore it is very important to protect the habitats of these species, ensure the continuity of their generations. The disappearance of these endemic species from our country means to disappear from the world. This review has been given in order to give some information about the endangered Lilium species of Turkey and conservation actions on these species in Turkey flora and take attention to the issue.

  18. Geothermal energy development in Turkey

    1990-01-01

    Geothermal fields in Turkey are related to rather complex zones of collision between the Eurasian and African continents, and penetration of the Arabian plate into the Anatolian continental mass. These processes gave rise to fracturing of the lithosphere and eruption of magmas. Geothermal regional assessment studies have proven several low enthalpy sources and some high enthalpy fields suitable for electricity generation. This paper summarizes developments in exploration-drilling and give examples of direct utilization implemented in recent years

    Eyre, Bradley; McConchie, David

    1993-05-01

    Sedimentology is of increasing importance in environmental research, particularly environmental pollution studies, where past trends in environmental processes need to be combined with data on present conditions to predict likely future changes—the past and present as a key to the future. Two examples are used to illustrate the role of sedimentology in assessing the influence of major processes on the transport, accumulation, deposition and modification of contaminants in fluvial/estuarine systems and in developing environmental management plans. Example 1 shows that when assessing nutrient behaviour in fluvial/estuarine depositional settings, it is important to examine the partitioning of phosphorus between grain size fractions to evaluate the sedimentological processes which control the dispersion and trapping of these contaminants. Example 2 shows that in studies of anthropogenic metal inputs to modern depositional settings, lateral and stratigraphic trends in sediment texture and mineralogy should be examined, in addition to trends in metal loads and evaluation of the prevailing physical, chemical and biological processes that may influence metal mobility and dispersion. Clearly, basic sedimentological data should form part of any assessment of potentially contaminated sites and part of investigations into the dispersion and trapping of contaminants in fluvial systems. These data are also required for rational environmental management to ensure that planning decisions are compatible with natural environmental constraints.

    Analysis suggests that a high hydraulic conductivity (K) zone is associated with a former river channel at the Portsmouth Gaseous Diffusion Plant (PORTS). A two-dimensional (2-D) and three-dimensional (3-D) groundwater flow model was developed base on a sedimentological model to demonstrate the performance of a horizontal well for plume capture. The model produced a flow field with magnitudes and directions consistent with flow paths inferred from historical trichloroethylene (TCE) plume data. The most dominant feature affecting the well's performance was preferential high- and low-K zones. Based on results from the calibrated flow and transport model, a passive groundwater collection system was designed and built. Initial flow rates and concentrations measured from a gravity-drained horizontal well agree closely to predicted values

    2002-01-01

    Full Text Available Bathymetric and sedimentological data from water depths between 3 and 28 meters are the basis of a detailed bathymetric map of the Itaipú Embayment and an understanding of its sedimentary dynamics. Shallower than 16 meters the contours are parallel to the shoreline whereas the morphology of the deeper bottom is influenced by the Menina, Mãe, and Pai islands. Medium sand is prevalent, with local variations in more protected or less protected areas. Minor amount of black mud possibly derives from the Itaipú Lagoon. Siliciclastic granules and pebbles may be relict. The Itaipú Embayment's bottom morphology is controlled by stormy waves and the calmer easternmost part of the embayment presents a tendency to accumulate finer sediments.

    Pulham, Andrew J.

    1995-01-01

    The cusiana field (BP, Ecopetrol, Total and Triton is located in the llanos foothills of Eastern Colombia. There are three key reservoirs in the Cusiana field; the late Eocene to Early Oligocene Mirador Formation, the late Paleocene Barco Formation and the Santonian to Late Campanian Guadalupe Formation. The Mirador Formation contains over 50% of the original oil in place. Production for 1995 is planned at 130.000 barrels of oil per day (bopd; daily average), principally for the Mirador Formation with some production from the Guadalupe Formation. The mirador formation has therefore been the focus of a detailed reservoir description study aimed at understanding reservoir performance and putting a foundation in place for long-term reservoir management. The Mirador Formation comprises sandy (>60%), high frequency sequences dominated by the deposits of incised valleys. This paper describes the sedimentology and stratigraphy of the Mirador and the methodology chosen to construct a reservoir model fit for reservoir simulation

    Carey, S.; Sigurdsson, H.; Dhondt, S.; Espindola, J. M.

    1993-01-01

    The K/T boundary sequence is exposed in uplifted carbonate sediments of the southwest peninsula of Haiti. It is found at 15 localities within the Beloc formation, a sequence of limestone and marls interpreted as a monoclinal nappe structure thrust to the north. This tectonic deformation has affected the K/T boundary deposit to varying degrees. In some cases the less competent K/T deposit has acted as a slip plane leading to extensive shearing of the boundary layer, as well as duplication of the section. The presence of glassy tektites, shocked quartz, and an Ir anomaly directly link the deposit to a bolide impact. Stratigraphic and sedimentological features of the tripartite sequence indicate that it was formed by deposition from ballistic fallout of coarse tektites, emplacement of particle gravity flows and fine grained fallout of widely dispersed impact ejecta.

    Many oil and gas reservoirs in the world are reserved in fossil carbonate sediment. Knowledge of modern carbonate sedimentology is important for a better understanding of ancient carbonate sedimentation. Equatorial coral reefs comprise almost half of the world coral reef production, and yet their dynamics, distributions, and cycles are still not well understood. Contrary to their subtropical counterpart, South East Asian carbonate system is known to be strongly influenced by the combination of oceanographic and climatic conditions. Hence carbonate sediments in the tropics have a distinct depositional system, and ought to be treated differently since common distribution models were developed from the (sub-tropical) Atlantic and Pacific regions. This paper systematically summarizes carbonate sediment studies in Seribu Islands and its dominant oceanographic configuration to provide insights and a sense of research direction in the future.

    1994-02-01

    The problems caused by the solid particle transport in rivers, dams, harbors, estuaries and in navigation channels have considerable economical consequences. The technical difficulties met when trying to limit or manage these problems are very important because of lack of knowledge. The nuclear gages and the radioactive tracers can be the measurement and monitoring means which, associated to the conventional techniques, permit to develop strongly the knowledge in the solid transport field. This report gives the modes of solid transport and the problems caused by these transports and exposes the physical properties of the fine sediments and their behavior under the hydrodynamic effects. In the same way, it deals with the theory of the nuclear gages, often applied in dynamic sedimentology and gives some examples of their applications. 29 refs., 35 figs., 5 tabs. (F.M.)

    1986-01-01

    Detailed structural and sedimentological studies have been conducted in two areas near the Val Vedello uranium mine in northern Italy. These studies indicate that both the Variscan basement (locally called the Orobic basement) and the Permian cover rocks were thrust southward during the Alpine orogeny. Variscan mylonitic zones were rejuvenated during the Alpine orogeny and became fault boundaries for the Permo-Triassic basins. Alpine faults also are related to contemporaneous east-west folds and these faults have displaced Permo-Triassic uranium deposits. Uranium mineralisation is attributed to a Late Permian to Triassic geothermal event which leached uranium from Permian ignimbrites and transported it along Permo-Triassic faults. Detailed mapping indicates that the host sediments formed in an arid, closed basin characterised by alluvial fans and perennial saline lakes. (orig.)

    2017-06-01

    Full Text Available This is a field-based work that describes the stratigraphy and sedimentology of the Andatza Conglomerate Formation. Based on facies analysis three facies associations of a coarse-grained turbidite system and the related slope have been identified: (1 an inner fan of a turbidite system (or canyon and (2 a low- and (3 a high-gradient muddy slope respectively. The spatial distribution of the facies associations and the palaeocurrent analysis allow to interpret a depositional model for the Andatza Conglomerates consisting of an L-shaped, coarse-grained turbidite system, whose morphology was structurally controlled by synsedimentary basement-involved normal faults. The coarse-grained character of the turbidite system indicates the proximity of the source area, with the presence of a narrow shelf that fed the turbidite canyon from the north.

    Three tidal marshes in Able Tasman National Par, New Zealand, were studied using geochemical, sedimentological and radiometric dating techniques. Charcoal and plant material samples were taken from one core in each inlet for 14 C analysis. radiocarbon ages were converted to dendrocalibrated years . All samples produced a terrestrial 13 C signal. Near surface samples were date d by measuring 137 Cs. A 1700 year record of catastrophic saltwater inundations (CSI) events (Tsunami) was produced. Up to four such events were identified, with ruptures of one or more of the Wellington, Wairarapa and Alpine Faults being the most likely tsunamigenic source. CSI signatures include: peaks in Fe and/or S, a peak in fines and contemporaneous or delayed peaks in organic content and/or loss on ignition (LOI). Geochemical data in association with grain size analyses proved to be a valuable tool in the interpretation of these events

    2009-01-01

    A previous study on seabed sediments of the Bay of Cadiz (SW of Spain) enabled us to identify several relations between sedimentological variables and activity concentrations of environmental radionuclides such as 137 Cs, 226 Ra, 232 Th and 40 K. In this paper the study has been extended to a large neighbouring inter-tidal area in order to establish if the above mentioned models can be generalized. As a result we have determined that the measured activity concentrations are closely to the values predicted by the theoretical models (correlation coefficient range = 0.85-0.93). Furthermore, the proposal model for granulometric facies as a function of activity concentrations of the abovementioned radionuclides provides for the sediments distribution a representation which agrees with the values of the tidal energy distribution obtained using numeric models calibrated with experimental data from current meters and water level recorders

    Profiles of artificial fallout (such as 137 Cs) and natural radioactivity radionuclides in sediment cores are useful tools to study sedimentological properties of different aquatic environments as well as to evaluate average sedimentation rates. In the Portil lagoon, a small natural reservoir located in Huelva province (southwest of Spain), and through the analysis of 210 Pb, 226 Ra, 137 Cs, 238 U and 210 Po vertical profiles in sediment cores, it is shown how the accumulative or transport character of the collection zones may be inferred. In the accumulation zone of the lagoon the influence of focusing effects has been analysed and an average sedimentation rate has been determined through 210 Pb in one sediment core. This 210 Pb-sedimentation rate is consistent with sediment dating based on the 137 Cs data. (author)

    Full Text Available The purpose of this study is to appraise the physicochemical properties of mangrove sediments and their influence on neoichnological properties produced by different crab species from Korangi Creek (S1 and Sandspit backwater areas (S2 and S3, Karachi. The significant spatial, seasonal and tidal differences (p <0.05 were examined in %moisture, %porosity and sorting coefficient Φ.The significant spatial and seasonal variations were observed in total organic matter, mean Φ, skewness Φ and kurtosis Φ of sediment. Neoichnological properties (burrow number, diameter and total burrow opening area were observed with significant differences among the macrohabitat (stations and microhabitat (tidal levels. The correlation analysis indicated that the neoichnological properties are strongly linked with sedimentological properties such as water contents, total organic matter and textural parameters. This study could be employed to distinguish between different paleoenvironmental controlling factors, predicated on similar paleoichnological features made by similar fossil organisms in a mangrove environment.

    2006-06-01

    Full Text Available The VST02 cruise carried out in the summer of 2002 was focused at sedimentologic and volcanologic researches over selected areas of the deep portion of the Tyrrhenian sea. Chirp lines and seafloor samples were collected from the Calabrian slope surrounding Stromboli island, in the Marsili deep sea fan, in the Vavilov basin and in the Vavilov seamount. Submarine volcanic activity, both explosive and effusive, is occuring in the Stromboli edifice. Explosive submarine volcanism affects also the shallowest areas of the Vavilov seamount. Submarine carbonate lithification has been observed on the sediment-starved flanks of the Vavilov seamount. Acoustic transparent layers make up the recentmost infill of the Gortani basin, the easternmost portion of the Vavilov basin. Channels comprised of a variety of architectural elements and depositional lobes are the main elements of the Marsili deep-sea fan where, apparently, sedimentation occurs mainly through debris flow processes.

  13. New sedimentological and palynological data from surface Miocene strata in the central Amazonas Basin area

    Directory of Open Access Journals (Sweden)

    Emílio Alberto Amaral Soares

    Full Text Available ABSTRACT The scarcity of stratigraphic data has hindered the demarcation of the outcropping area of Miocene deposits of the Amazon Basin, represented informally by the Novo Remanso Formation. Moreover, this unit is characterized by a sparse and irregular geographic distribution due to its sedimentological features and rare fossil content. Miocene deposits cropping out in central Amazonas Basin area were described in sedimentological terms and analyzed palynologically. All analyses were undertaken in samples collected at the Uatumã River banks (Itapiranga and São Sebastião do Uatumã cities. Lithostratigraphic data shows that Novo Remanso Formation consists of sandstones, with subordinate conglomerates and pelites, characteristic of a meandering fluvial paleosystem, with fluvial channel, point bar, floodplain and crevasse splay facies. The palynoflora retrieved from five samples consists exclusively of continental-origin palynomorphs dominated by angiosperms species. Trilete spores are well represented, while gymnosperms pollen grains are minor components. The presence of Psilastephanoporites tesseroporus, Syncolporites poricostatus, Jandufouria seamrogiformis and Polypodiaceoisporites potoniei ensure these deposits fits into the Grimsdalea magnaclavata palynozone (Regali et al. 1974a, b, and the Grimsdalea magnaclavata/Crassoretitriletes vanraadshooveni palynozones of Jaramillo et al. (2011 considered Middle Miocene age. This age is confirmed by the zonation of Jaramillo et al. (2011, based on the LADs of Bombacacidites baumfalki (11.57Ma and Crototricolpites annemariae (12.91Ma; and the FAD of Psilastephanoporites tesseroporus (14.00Ma. With these new data presented herein, it is possible to assume that the Miocene strata represented by the Novo Remanso Formation covers a larger area in the basin than previously considered, and that it may be extended for about 300 km until the Manacapuru village, indicating a Miocene subsidence phase.

    Melut Basin in Sudan is regionally linked to the Mesozoic-Cenozoic Central and Western African Rift System (CWARS). The Paleocene Yabus Formation is the main oil producing reservoir in the basin. It is dominated by channel sandstone and shales deposited in fluvial/lacustrine environment during the third phase of rifting in the basin. Different scales of sedimentological heterogeneities influenced reservoir quality and architecture. The cores and well logs analyses revealed seven lithofacies representing fluvial, deltaic and lacustrine depositional environments. The sandstone is medium to coarse-grained, poorly to moderately-sorted and sub-angular to sub-rounded, arkosic-subarkosic to sublitharenite. On the basin scale, the Yabus Formation showed variation in sandstone bodies, thickness, geometry and architecture. On macro-scale, reservoir quality varies vertically and laterally within Yabus Sandstone where it shows progressive fining upward tendencies with different degrees of connectivity. The lower part of the reservoir showed well-connected and amalgamated sandstone bodies, the middle to the upper parts, however, have moderate to low sandstone bodies' connectivity and amalgamation. On micro-scale, sandstone reservoir quality is directly affected by textures and diagenetic changes such as compaction, cementation, alteration, dissolution and kaolinite clays pore fill and coat all have significantly reduced the reservoir porosity and permeability. The estimated porosity in Yabus Formation ranges from 2 to 20% with an average of 12%; while permeability varies from 200 to 500 mD and up to 1 Darcy. The understanding of different scales of sedimentological reservoir heterogeneities might contribute to better reservoir quality prediction, architecture, consequently enhancing development and productivity.

  15. Sedimentology and ichnology of Neogene Coastal Swamp deposits in the Niger Delta Basin, Nigeria

    Full Text Available Often analyses of depositional environments from sparse data result in poor interpretation, especially in multipartite depositional settings such as the Niger Delta. For instance, differentiating channel sandstones, heteroliths and mudstones within proximal environments from those of distal facies is difficult if interpretations rely solely on well log signatures. Therefore, in order to achieve an effective and efficient interpretation of the depositional conditions of a given unit, integrated tools must be applied such as matching core descriptions with wireline log signature. In the present paper cores of three wells from the Coastal Swamp depositional belt of the Niger Delta are examined in order to achieve full understanding of the depositional environments. The well sections comprise cross-bedded sandstones, heteroliths (coastal and lower shoreface and mudstones that were laid down in wave, river and tidal processes. Interpretations were made from each data set comprising gamma ray logs, described sedimentological cores showing sedimentary features and ichnological characteristics; these were integrated to define the depositional settings. Some portions from one of the well sections reveal a blocky gamma ray well log signature instead of a coarsening-upward trend that characterises a shoreface setting while in other wells the signatures for heteroliths at some sections are bell blocky in shaped rather than serrated. Besides, heteroliths and mudstones within the proximal facies and those of distal facies were difficult to distinguish solely on well log signatures. However, interpretation based on sedimentology and ichnology of cores from these facies was used to correct these inconsistencies. It follows that depositional environment interpretation (especially in multifarious depositional environments such as the Niger Delta should ideally be made together with other raw data for accuracy and those based solely on well log signatures should

    1980-10-01

    The sedimentology of four sandstones was studied in outcrop and in the subsurface on the farm Riet Kuil 307, near Beaufort West. Only two of these sandstones are mineralised. These are four surface and two subsurface uranium anomalies and one surface uranium anomaly. The sedimentological study was made by means of 47 vertical profiles measured across and adjacent to the surface anomalies as well as 11 core-logs, which intersected the subsurface anomalies. The unmineralised sandstones are included in this study. A total of 19 sedimentary facies was recognised within the fluvial sandstone sequence according to the criteria of grain-size and sedimentary structure. Transitions between the facies were subjected to a Markov chain analysis in order to delineate Markov-dependent transitions. Uranium mineralisation is almost entirely confined to the coarser-grained sedimentary facies, which probably acted as suitable aquifers for the transport of uraniferous solutions prior to the precipitation of the uranium. Horizontally bedded sandstone facies comprises 60 per cent of the total cumulative thickness of mineralisation. The nature of the bedding of this facies may have provided a more effective permeability zone for the transport of uraniferous solutions. This facies contains an abundance of carbonaceous material which acted as an important indirect reductant for the precipitation of uranium from solution. The direct reductant was most probably H 2 S produced by enaerobic bacteria acting on this carbonaceous material shortly after deposition of the sediments. Carbonaceous material also occurs in the other mineralised facies and is considered to be the major control on the mineralisation in the uranium-bearing sandstones

    Hidden River Cave is part of a cave system hydrogeologically related to Mammoth Cave in Kentucky and is a multi-level active cave system with 25km of mapped passages. Upper levels experience flow during flood events and lower levels have continuously flowing water. Improper industrial and domestic waste disposal and poor understanding of local hydrogeology lead to contamination of Hidden River Cave in the early 1940s. Previously used for hydroelectric power generation and as a source of potable water the cave was closed to the public for almost 50 years. A new sewage treatment plant and remediation efforts since 1989 have improved the cave system's health. This project focuses on sedimentological studies in the Hidden River Cave system. Water and sediment transport in the cave are being investigated using sediment cores, surface sediment samples and water level data. An Itrax core scanner is used to analyze sediment cores for elemental concentrations, magnetic susceptibility, radiography, and high resolution photography. Horizons of metal concentrations in the core allow correlation of sedimentation events in the cave system. Thecamoebian (testate amoebae) microfossils identified in surface samples allow for further constraint of sediment sources, sedimentation rates, and paleoclimatic analysis. Dive recorders monitor water levels, providing data to further understand the movement of sediment through the cave system. A general time constraint on the sediment's age is based on the presence of microplastic in the surface samples and sediment cores, and data from radiocarbon and lead-210 dating. The integration of various sedimentological data allows for better understanding of sedimentation processes and their record of paleoenvironmental change in the cave system. Sediment studies and methodologies from this project can be applied to other karst systems, and have important applications for communities living on karst landscapes and their water management policies.

    Due to the diversification efforts of energy sources, use of natural gas that was newly introduced into Turkish economy, has been growing rapidly. Turkey has large reserves of coal, particularly of lignite. The proven lignite reserves are 8.0 billion tons. The estimated total possible reserves are 30 billion tons. Turkey, with its young population and growing energy demand per person, its fast growing urbanization, and its economic development, has been one of the fast growing power markets of the world for the last two decades. It is expected that the demand for electric energy in Turkey will be 580 billion kWh by the year 2020. Turkey's electric energy demand is growing about 6-8% yearly due to fast economic growing. This paper deals with energy demand and consumption for environmental issues in Turkey.

    2009-02-01

    Transnational tobacco companies (TTCs) considered Turkey an important, potential investment market because of its high consumption rates and domestic commitment to tobacco. This paper outlines how British American Tobacco (BAT) attempted to establish a joint venture with the government monopoly TEKEL, while waiting for privatisation and a private tender. Analysis of tobacco industry documents from the Guildford Depository and online tobacco document sources. BAT failed to establish a market share in Turkey until 2000 despite repeated attempts to form a joint venture with Turkey's tobacco monopoly, TEKEL, once the market liberalised in the mid 1980s. BAT's failure in the Turkish market was due to a misguided investment strategy focused solely on acquiring TEKEL and is contrasted with Philip Morris success in Turkey despite both TTCs working within Turkey's unstable and corrupt investing climate.

  6. Global energy perspective of Turkey

    2006-01-01

    Global energy demand is growing rapidly at an average rate of 4% per year in parallel with the economy while EU-25 has only 0,8% during the last decade. Total primary energy supply is 87 818 000 toe of which 72% was imported; in comparison the average dependency rate is 49,5% in the EU. Such excessive dependency creates harmful effects on the national economy. Oil and natural gas imports bill was 19,5 billion US $ in 2005. Primary energy demand growth rate is twice as much of the production rate in the period 1980 2004. Fossil fuels accounts for 86% of Turkeys global energy supply in 2004. Population growth rate is one of the major parameters affecting the energy balance. Energy and electricity consumptions per capita are still one third of the EUs average.. Turkeys coal reserves needs to be utilized at higher rate and hydropower, wind power and geothermal energy potentials should be developed in order to decrease the imported energy dependence, soon. Due to the buy or pay bilateral agreements with suppliers, storage capabilities should be realized for excessive natural gas supply. Turkeys average growth rate of electricity production is 8,1% while installed capacity has 8,5% for the last 25 years. The present total installed capacity is 39 020 MW in which renewables has a share of 34%. Total electricity production was 162 TWh in 2005 of which 75,4% was supplied by thermal power plants. Share of natural gas is 44% of the annual electricity production. Considering the present power plants and the ones under construction, electricity supply and demand will be in balance till the year of 2010 (with high demand scenario) or 2015 (with low demand scenario). Nuclear power is being considered for electricity supply security after 2015. But, the general approach for supply security is first to develop the domestic coal reserves, renewable energy resources.

    Multimedia will be regarded as essential tools for children to create their new world. The effects of television on young children's life have been well studied. Television differs, however, from other media, including the movies, in its pervasive impact on children. Children spend more time watching television than any other activity except sleeping. Overall 31% of children spent at least 4 hours a day watching television during weekday and 71.7% during weekend in Turkey. Television's influence on children is a function of the length of time they spend watching and the cumulative effect of what they see. Television may be a cause as well as a solution for many serious childhood problems. Excessive viewing of television has also been linked to aggressive behavior, violence, childhood obesity. On the other hand, television may act as a socializing agent and as a learning tool if the recommendations of American Academy of Pediatrics is learned by pediatricians, parents and broadcasters. The use of home personal computers in urban residence increased from 3.2% in 1993 to 6.5% by January 1998 in Turkey. Around 20% of computer households reported owing a modem. Internet has been using only for 5 years in Turkey. Nearly 40% of computer households also used CD-ROM equipment. The percentage of schools that have a computer laboratory is only 2.64%. On the other hand, multimedia allows students to move away from a uniform education for everyone to assert individual identity, liberalize education and management. It seems likely that, within the next few years, most of the countries with substantial internet infrastructure will use the internet as the major medium for disseminating information, including information on children. To prepare students for such a world demands that educational systems make the best possible use of all knowledge and technologies currently available.

    2001-01-01

    Geographically, Turkey is situated in an area where malaria is very risky. The climatic conditions in the region are suitable for the malaria vector to proliferate. Due to agricultural infrastructural changes, GAP and other similar projects, insufficient environmental conditions, urbanization, national and international population moves, are a key to manage malaria control activities. It is estimated that malaria will be a potential danger for Turkey in the forthcoming years. The disease is located largely in south-eastern Anatolia. The Diyarbakir, Batman, Sanliurfa, Siirt, and Mardin districts are the most affected areas. In western districts, like Aydin and Manisa, an increase in the number of indigenous cases can be observed from time to time. This is due to workers moving from malaria districts to western parts to final work. Since these workers cannot be controlled, the population living in these regions get infected from indigenous cases. There were 84,345 malaria cases in 1994 and 82,096 in 1995, they decreased to 60,884 in 1996 and numbered 35,456 in 1997. They accounted for 36,842 and 20,963 in 1998 and 1999, respectively. In Turkey there are almost all cases of P. vivax malaria. There are also P. vivax and P. falciparum malaria cases coming from other countries: There were 321 P. vivax cases, including 2 P. falciparum ones, arriving to Turkey from Iraq in 1995. The P. vivax malaria cases accounted for 229 in 1996, and 67, cases P. vivax including 12 P. falciparum cases, in 1997, and 4 P. vivax cases in 1998 that came from that country. One P. vivax case entered Turkey from Georgia in 1998. The cause of higher incidence of P. vivax cases in 1995, it decreasing in 1999, is the lack of border controls over workers coming to Turkey. The other internationally imported cases are from Syria, Sudan, Pakistan, Afghanistan, Nigeria, India, Azerbaijan, Malaysia, Ghana, Indonesia, Yemen. Our examinations have shown that none of these internationally imported cases

    Full Text Available This paper is briefly dealing with the current situation in Afghanistan within the context of Turkey’s increasing role in Afghanistan. Turkish-Afghani relations are examined in terms of politics and economy while Turkish foreign policies towards Afghanistan and the Turkish-Pakistani-Afghani triple summit attempts are analyzed. Additionally, Turkey’s security and socio-economic contributions in Afghanistan are emphasized. Turkey’s unwillingness to send troops to Afghanistanfor operational purposes that is frequently debated in national and international circles has been evaluated by stating the advantages and disadvantages of such decision. Turkey’s quiet approach between 2001 and 2004 towards Afghanistan, which have been energizing since 2005 and Foreign Minister Ahmet Davutoğlu’s visit to Afghanistan on June 2009 have been dealt as well. By considering Davutoglu’s policies, aiming to introduce Turkey as a global actor and as the term President of the UNSC (the UN Security Council, it seems that Turkey is preparing to play a more active role in Afghanistan.

  13. Understanding Urban Regeneration in Turkey

    2016-06-01

    In Turkey, rapid population growth, informal settlements, and buildings and infrastructures vulnerable to natural hazards are seen as the most important problems of cities. Particularly disaster risk cannot be disregarded, as large parts of various cities are facing risks from earthquakes, floods and landslides and have experienced loss of lives in the recent past. Urban regeneration is an important planning tool implemented by local and central governments in order to reduce to disaster risk and to design livable environments for the citizens. The Law on the Regeneration of Areas under Disaster Risk, commonly known as the Urban Regeneration Law, was enacted in 2012 (Law No.6306, May 2012). The regulation on Implementation of Law No. 6306 explains the fundamental steps of the urban regeneration process. The relevant institutions furnished with various authorities such as expropriation, confiscation and changing the type and place of your property which makes urban regeneration projects very important in terms of property rights. Therefore, urban regeneration projects have to be transparent, comprehensible and acceptable for all actors in the projects. In order to understand the urban regeneration process, the legislation and projects of different municipalities in Istanbul have been analyzed. While some steps of it are spatial data demanding, others relate to land values. In this paper an overview of the urban regeneration history and activities in Turkey is given. Fundamental steps of the urban regeneration process are defined, and particularly spatial-data demanding steps are identified.

    The activity concentrations and absorbed gamma dose rates due to primordial radionuclides and 137 Cs have been ascertained in 222 soil samples in 18 counties of the Trabzon province of Turkey using a HPGe detector. The mean activity concentrations of 238 U, 232 Th, 40 K and 137 Cs in soil samples were 41, 35, 437 and 21 Bq kg -1 , respectively. Based on the measured concentrations of these radionuclides, the mean absorbed gamma dose in air was calculated as 59 nGy h -1 and hence, the mean annual effective dose due to terrestrial gamma radiation was calculated as 72 μSv y -1 . In addition, outdoor in situ gamma dose rate (D) measurements were performed in the same 222 locations using a portable NaI detector and the annual effective dose was calculated to be 66 μSv y -1 from these results. The results presented in this study are compared with other parts of Turkey. Radiological maps of the Trabzon province were composed using the results obtained from the study. - Highlights: → →The study highlights activity concentrations of 238 U, 232 Th, 40 K and 137 Cs in soil. → The absorbed gamma dose in air and the mean annual effective dose were calculated. → The calculated results compared with outdoor in situ gamma dose measurements. → Radiological maps of the Trabzon province were created using ArcGIS applications. → The results will be valuable data for future estimations of radioactive pollution.

  15. Importance of biomass energy sources for Turkey

    International Nuclear Information System (INIS)

    Demirbas, Ayhan

    2008-01-01

    Various agricultural residues such as grain dust, crop residues and fruit tree residues are available in Turkey as the sources of biomass energy. Among the biomass energy sources, fuelwood seems to be one of the most interesting because its share of the total energy production of Turkey is high at 21% and the techniques for converting it to useful energy are not necessarily sophisticated. Selection of a particular biomass for energy requirements is influenced by its availability, source and transportation cost, competing uses and prevalent fossil fuel prices. Utilization of biomass is a very attractive energy resource, particularly for developing countries since biomass uses local feedstocks and labor. Like many developing countries, Turkey relies on biomass to provide much of its energy requirement. More efficient use of biomass in producing energy, both electrical and thermal, may allow Turkey to reduce petroleum imports, thus affecting its balance of payments dramatically. Turkey has always been one of the major agricultural countries in the world. The importance of agriculture is increasing due to biomass energy being one of the major resources in Turkey. Biomass waste materials can be used in Turkey to provide centralized, medium- and large-scale production of process heat for electricity production. Turkey's first biomass power project is under development in Adana province, at an installed capacity of 45 MW. Two others, at a total capacity of 30 MW, are at the feasibility study stage in Mersin and Tarsus provinces. Electricity production from biomass has been found to be a promising method in the nearest future in Turkey

  16. Tectonic and sedimentological environments of sandstone-hosted uranium deposits, with special reference to the Karoo Basin of South Africa

    International Nuclear Information System (INIS)

    Le Roux, J.P.

    1985-01-01

    The principal tectonic and sedimentological settings for sandstone-hosted uranium deposits are described. Back-arc basins filled with post-Silurian, fluvial sediments bordering subduction zone magmatic arcs of calc-alkaline composition are considered favourable tectonic environments. The basins should be closed to prevent excessive oxidation of the sediments. Uranium deposits are concentrated near basin rims in the transition zone between uplift and basin subsidence, because of favourable sedimentary facies in those areas. Syn- and post-depositional deformation could have affected the localisation of uranium ore-bodies, while intrusive centres or uplifted arcs commonly have surrounding aprons of potential host rocks. Stratigraphic zoning is also related to source area tectonics and can be used to predict favourable sedimentary environments. Sedimentological processes had a direct influence on the permeability and carbonaceous matter content of sandstones and therefore have often controlled the localisation of ore-bodies. (author)

  17. Landscape changes based on sedimentological and geochemical studies in the region of Brudzeń Duży

    2014-03-01

    Full Text Available Sedimentological and geochemical research carried out in North- West Mazovia, central Poland, allowed the determination of landscape transformation in relation to the history of human settlement. The types of sediments subject to analysis included palaeochannel filling, accumulation on the river floodplain and colluvial deposits. The absolute ages of sediments and their sedimentological features allow the conclusion that the first response to human activity in the area is recorded in the overbank deposits in the Skrwa River valley as a result of the Wielbarska Culture in 200-300 AD. Subsequently, fan accumulation at the mouths of gullies started around the 12th-13th centuries AD. Frequent changes of sediment properties have been observed since the early Middle Ages. The subsequent anthropogenic impact on homogenous deposits is recorded in increased heavy metal concentration in vertical geological profiles.

  18. Practical application of food irradiation in Turkey

    Cetinkaya, N.; Erhan, I.C.

    2002-01-01

    Turkey is the world's leading producer and exporter of dried fruits (dried figs, raisins,and dried apricots etc.) and nuts (hazelnuts, wall nuts, pistachios, peanuts etc.) all of which have to be fumigated by methyl bromide a few times prior to export. Last fumigation is obligatory before shipment according to current quarantine treatment. Methyl Bromide (MeBr) fumigation is the most commonly used insect quarantine treatment for dried fruits and nuts in Turkey to protect from potential infestations. In accordance with the Montreal Protocol, Turkey as an Article 5(1) country will take actions to regulate and take measures to phase-out MeBr use. So, Turkey has to total phase-out in 2015 but according to Turkey MeBr Phase-out Action Plan prepared and published by The Ministry of Agriculture and Rural affairs in 2001, using MeBr should be reduced for stored commodities by 50 % by 2002 and phased-out totally by 2004. Irradiation technology is ready as an alternative to MeBr fumigation under the Action Plan of Turkey. Intensive research studies on food irradiation in Turkey have started in early 1970's and have still been continued. After careful and intensive works of all related authorities and specialists for a long period and with the help of ICGFI, the food irradiation regulation of Turkey was published in Official Newspaper on November 6, 1999. Having the Food Irradiation Regulation has supported to initiate commercialization study in Turkey in Co-operation with IAEA (TUR 5022). Feasibility study of a commercial food irradiation facility for the potential application of food irradiation in Turkey was prepared by IAEA experts Dr.M.Ahmed and Ir.

    Serum samples and tracheal cultures were collected from eastern wild turkeys (Meleagris gallopavo sylvestris) trapped for relocation in South Carolina (USA) during 1985 to 1990. Sera were tested for Mycoplasma gallisepticum and M. synoviae by the rapid plate agglutination and hemagglutination inhibition tests and were found to be negative. Tracheal cultures were negative for all pathogenic Mycoplasma spp., including M. gallisepticum, M. synoviae, M. meleagridis, and M. iowae. However, M. gallopavonis was isolated from every group of wild turkeys tested in 1986 to 1990. These data suggest that M. gallopavonis, which is generally considered nonpathogenic, may be a common microorganism in eastern wild turkeys.

    In light of the strong correlation between exchange rate movements and domestic prices in Turkey, it is important to assess the impact of the exchange rate on domestic prices, in particular as Turkey moves to an inflation targeting regime. This paper uses a recursive vector autoregression model to investigate the impact of exchange rate movements on prices in Turkey. We find that (i) the impact of the exchange rate on prices is over after about a year, but is mostly felt in the first four mon...

  4. Sedimentology and Rock Magnetism of Bailey River Peat Cores, Sudbury Area: Preliminary Results

    Magnetic measurements on peat can reveal atmospheric anthropogenic contamination. Two cores were collected from a marsh surrounding the Bailey River, 10 km north of Sudbury, Ontario, using a Russian peat borer. The BR1 core (1.4 m) was collected right at the river's edge, whereas the BR2 core (2.5 m) was collected about 50 m away from the river's edge, close to the edge of the marsh and near the forest. Significant sedimentological variation between the two cores was observed: core BR1 had several centimeter to decimeter scale fine to coarse grey sand layers at 0.14 m, 0.46 m and 0.87 m between thicker organic-rich (peat) zones, whereas core BR2 had only one 5 cm sand-rich layer at 0.94 m within the organic-rich material. The cores were subsampled at 2.5 cm intervals for laboratory magnetic analysis. Volume susceptibility was measured using a Bartington MS2B meter, and mass-specific susceptibility was then calculated. In core BR1, the sand layers had relatively higher susceptibility (13 x 10-8 m3/kg) , while the organic rich layers had very low susceptibility (0 - 2 x 10-8 m3/kg). In core BR2, which had little sand, the susceptibility variation was dominated by higher values near-surface (10 x 10-8 m3/kg), and very low susceptibility (0.3 x 10-8 m3/kg) below 0.3 m depth. Since the lithology in this core did not vary substantially, susceptibility variations may be controlled by anthropogenic deposition in the near-surface during the peak mining and smelting decades. These preliminary results suggest that any anthropogenic signal in core BR1 appears to be masked by the sedimentological variation. On pilot results from eight samples in core BR1, saturation isothermal remanence acquisition showed 95% saturation by 200 mT, and the S-ratios (0.3T/0.9T) were above 0.93, suggesting that magnetite is the major magnetization carrier. In core BR2, six out of eight samples showed similar results; however, two samples had slightly more higher coercivity minerals (90% saturation

    Beach ridge landforms have been observed in different environments and in settings that range from polar to tropical. Their stratigraphy and sedimentology has received a limited amount of discussion in the literature (Tamura, 2012). In coastal geomorphology a beach ridge can be seen as a transitional deposit between onshore and offshore environments. They are regarded as representing high level wave action along a coastline. In the Caribbean the origin of beach ridges has been variously attributed to one of three extreme wave events: extreme swell, extreme storm or tsunami waves. Beach ridges are arranged in beach ridge plains where there is succession of the landforms and can be several kilometres long. Beach ridge accumulation is not continuous and the coast shows alternating accretion and erosion periods. The use of beach ridges as palaeostorm archives is therefore not straightforward. The temporal continuity of beach ridge formation is being assessed on the beach ridge plains of Anegada, British Virgin Islands (Lesser Antilles). This carbonate platform surrounded by a fringing reef contains two beach ridge plains. There are more than 30 ridges in the Atlantic facing- coast and around 10 in the south, Caribbean- facing coast. The sediments of the modern beaches are dominated by the sand fraction and are 100% biogenic origin due to the isolation of Anegada from terrestrial sediment sources. The beach ridge sections have been studied in different area of Anegada beach ridge plains and present low angle seaward-dipping bedding. The sand fraction is dominant in the stratigraphy with a few intact shells. At only one site were coral pebbles deposited in association with the sand fraction. Aeolian deposits represent the upper part of the beach ridges and reflect the stabilization of the beach ridges with ongoing accretion. The sedimentology of the contemporary beach and dunes will be discussed in terms of their implications for understanding beach ridge genesis and its

    The Black Sea has undergone alternating phases of lacustrine and marine environment over geological timescales directly related to its semi-enclosed character and to eustatic sea-level oscillations. During lowstand conditions, as during the last glacial period, the Black Sea was a giant lake disconnected from the global ocean. At that time, Black Sea water-level was controlled by regional climate, and by Eurasian rivers, including the Danube that acted as an outlet of European Ice Sheet and the Alpine ice cap. Thus, the paleo-mouth of the Danube river contains a high quality archive for the study of the paleohydrology of the Danube River and by extension of the European climate changes during the last 30 kyr. For this purpose, we have focused on the GAS-CS01 calypso long-piston core (33.4 m) which was taken during GHASS cruise (Ifremer, 2015) on the upper slope (240 m. depth) at about 25 km east of the Danube Canyon, i.e. in the sediment pile of the Danube paleo-mouth during the last glacial period. Our chronology reveals that core GAS-CS01 extends back to 31 cal kyr BP. The lithology of GAS-CS01 is characterized by clastic rythmites which are presented as a high-resolution Danube runoff proxy. Preliminary results of sedimentological and chronological analysis showed five peaks of terrestrial discharges between ca 31 and 14 ka BP, probably linked to five phases of the enhanced runoff during the studied period. In order to understand the origin and the depositional processes of this laminae, we combined sedimentary analysis (x-ray diffraction, x-ray fluorescence, grain size ...) and hyperspectral images analysis. Hyperspectral imagery is a non-destructive fast method classically used to quantify colour and provides data with high spatial (57-µm pixel size) and spectral (3 nm) resolution. The multi-proxy calibration is essential in order to obtain a high-resolution sedimentological dataset. This information allows us to reconstruct the nature and depositional

    Improved reservoir characterisation in the mature Brent Province of the North Sea, aimed at maximising both in-field and near-field hydrocarbon potential, requires a clearer understanding of sub-seismic stratigraphy and facies distributions. In this context, we present a regional, high-resolution sequence stratigraphic framework for the Brent Group, UK North Sea based on extensive sedimentological re-interpretation of core and wireline-log data, combined with palynostratigraphy and published literature. This framework is used to place individual reservoirs in an appropriate regional context, thus resulting in the identification of subtle sedimentological and tectono-stratigraphic features of reservoir architecture that have been previously overlooked. We emphasise the following insights gained from our regional, high-resolution sequence stratigraphic synthesis: (1) improved definition of temporal and spatial trends in deposition both within and between individual reservoirs, (2) development of regionally consistent, predictive sedimentological models for two enigmatic reservoir intervals (the Broom and Tarbert Formations), and (3) recognition of subtle local tectono-stratigraphic controls on reservoir architecture, and their links to the regional, Middle Jurassic structural evolution of the northern North Sea. We discuss the potential applications of these insights to the identification of additional exploration potential and to improved ultimate recovery. (author)

    Geothermal energy is a type of energy that are found in the accessible depth of the crust, in the reservoirs by way of the permeable rocks, specially in heated fluid. Geothermal system is made of 3 main components; heat source, reservoir, and fluid bearing heat. Geothermal system mechanism is comprise of fluid transmission. Convection current (heat transmission) is caused by heating and causes the fluid in the system to expand. Heated fluid with low density show tendency to rise in system. Geothermal system occurs with variable geophysics and geochemical properties. Geophysical methods can determine structural properties of shallow and deep reservoirs with temperature, mineralization, gas amount, fluid movement, faulting, and sudden change in lithostratigraphic strata. This study revealed possible reservoir structures and showed examples of geophysics and gas measuring results in Turkey which is wealthy in regard to Geothermal sources.

    Le Roux, J.P.

    1982-08-01

    A sedimentological study was conducted on the farm Klipbankskraal, north-west of Merweville. The orebody is located in the Poortjie Member at the base of the Teekloof Formation. The mineralised sandstone, S1, is a tabular lithosome deposited in an ephemeral, braided river environment. It consists of two major and several minor mesocycles, with the upper major cycle showing evidence of having inherited the drainage pattern of the lower mesocycle. The vector mean azimuth of the sequence as a whole is towards 059 degrees. The uranium is present as stacked, tabular lenses associated with permeable zones in the immediate vicinity of erosional inter-cycle contacts. Although no obvious relationship exists between the uranium and channels or bars, the distribution of plant material was controlled by the current velocities which also controlled the type of sedimentary structures. Uranium occurs preferentially in fissile-weathering (horizontal-bedded) sandstone and mud-pebble conglomerate, both permeable lithologies, and in mudstone or silt-stone. Uranium is genetically related to other elements such as Mn, Mo, Cu, Co and Pb, which must have been constituents of the ore fluid. Uraniferous granites in the source areas probaly supplied most of the uranium

    The use of fossil diatoms have sought to establish the evolution of the paleoecological and sedimentary processes, a section of paleolake in the warehouse Loma Camacho, Liberia-Guanacaste. The same has consisted of a volcano-sedimentary sequence of continental origin, shown as a lacustrine deposit, due to the presence of diatoms as their predominant fossil feature. The stratigraphy and sedimentology are established in detail of a portion of the formation of the Loma indicating, by this analysis, materials reworked of volcaniclastic origin and sedimentary deposits of lacustrine origin. The study has coincided to a sequence of tobitas, differentiated by their granulometry, microscopically corresponded to lodolites or claystones, with concentrations different of diatom fossils and crystals (predominantly quartz and biotic), in a clay matrix. Patterns of variation in the diatom paleocommunities are determined and have been recognized different species. General environmental conditions of paleolake are established, such as pH, productivity, solar radiation, salinity, etc. In addition, changes in diatom communities, sedimentation patterns and relations to the local and regional context were correlated setting dominant paleoenvironmental conditions for that depositional period in Loma Camastro. The main influence has been the seasonal changes in dry and rainy periods and constant volcanic activity of Volcan Rincon de la Vieja [es

    The Lopingian coal measures of southwestern China were deposited within a range of facies associations spanning a spectrum of settings from fluvial to marine carbonate platform. The transitional to terrestrial coal measures are dominated by siliciclastics, but they also contain fifteen laterally extensive marine bands (limestone beds and mudstone). These bands act as marker horizons that enable correlation between fully marine and terrestrial facies. Examination of this range of facies and their sedimentology has enabled the development of a high-resolution sequence stratigraphic framework. Set against the established backdrop of second-order Lopingian transgression, sixteen fourth-order sequences and three composite sequences (third-order) are recognized. Results show that, in the composite sequences, peat accumulation in the seaward parts of the study area predominantly correlates with early transgressive sequence sets (TSS), while in more landward areas it correlates with the middle TSS to late highstand sequence sets (HSS). Differences in peat-accumulation regimes within the sequence stratigraphic framework are attributed to variations in subsidence and background siliciclastic input rates in different depositional settings, with these combining to produce differences in the rate of accommodation change. The preservation of coal resources in the middle to late HSS in this area was most likely related to the rise of the regional base level throughout the Lopingian. (author)

    Full Text Available This work aims to improve the knowledge of the flood that took place in Valencia, Spain, in 1957. In other words, the aim is to test if it is possible to explain the flood waves with the incorporation of sediment cycle to a distributed hydrological model. Furthermore, this work aims to be aware of the current consequences of a similar event, taking into account land use changes, particularly, the urban rise in the lower basin, and the current flood defenses of the city. To do this, the hydrological model was implemented in the current basin situation. Once implemented, a reconstruction of precipitation at hourly discretization for the 1957 event was made and the sedimentological sub-model was calibrated. Then, the hydrographs in the chosen points were obtained. Finally, a simulation using the 1957 precipitation in the current basin situation was made, in order to be aware of the current consequences.

    The Picos II Paleontological Site (PIIPS), located in the city of Piranhas, in Alagoas State, is a fossil deposit with a pond-like geomorphological feature, a kind of peculiar deposit for the Quaternary of Northeast Brazil. A detailed taphonomic study is presented about the PIIPS assemblage, from material collection to the laboratory analysis. The conservation state of the collected fossils in PIIPS is different from that found in other tank deposits, showing a high degree of specimen preservation. Two taxa of pleistocenic mammals have been identified: Eremotherium laurillardi and Notiomastodon platensis, and fragments of an avian bone, whose taxonomic identification was not possible. The taphonomic analysis indicates that the deposited material experienced a short transportation in high-energy event, with a short period of subaerial exposure before the final burial, where at least the final disarticulation occurred in situ, which explains the high conservation level of the material. The sedimentological analysis made in each layer of the deposit corroborates the information related to the transport of the material, which were obtained in taphonomic analysis. Regarding these aspects, PIIPS reflects nearly non-biased biocenotic patterns. The well-preserved material found in PIIPS demonstrates the great potential of deposits with pond-like geomorphological features, with sidelines that are less steep than traditional tanks, providing smoother transport and accommodation for skeletal elements, which is a distinguishing factor in preserving fossils of vertebrates.

    Milodowski, A.E.

    1990-11-01

    A detailed petrographic, mineralogical and sedimentological study has been made of five drift sediment cores taken from shallow boreholes at Drigg, Cumbria, forming part of the British Geological Survey's migration test borehole array. The cores correspond to the aquifer in which tests are undertaken. The study shows that several discrete units can be recognised within the aquifer but that these may vary laterally by a considerable amount over short distances. The sands and silts comprising the aquifer zone are generally finely laminated and show an upwards coarsening of grain size. They are interpreted as proximal glacial sediments, possibly having been deposited in a lake or ponded basin. Petrographic analysis shows that most of the porosity is lined by detrital ferruginous illitic clay which coats the sand grains. Some evidence of feldspar dissolution is identified. Pyrite is also present as an important detrital component. In the upper part of the aquifer the pyrite has been largely oxidised to form secondary ferric oxide compounds. However, pyrite increases in abundance with depth and its preservation may reflect a variation in redox across the aquifer. (author)

    Le Roux, J.P.

    1982-08-01

    As part of its research program in the Karoo, NUCOR carried out a sedimentological investigation of the DR-3 deposit, discovered by JCI. It is located on the farm Drie Vaderlandsche Rietvalleyen, 40 km north of Laingsburg, in an unnamed sandstone package of the Abrahamskraal Formation. The orebody lies in an area affected by southward-dipping monoclines, which possibly originated because of basement faults during subsidence of the Karoo trough. These monoclines may be have locally altered the courses of rivers flowing from the source areas to the south-west. The S1-sandstone which hosts the uranium was probably deposited in a braided river environment of the Donjek type. The vector mean azimuth is towards 075 degrees for S1 and 062 degrees for the studied sequence as a whole, but towards the east there is a marked change in the palaeocurrent direction. On a more regional scale, preliminary investigations indicate the braided river system was at least 5 km wide. Uranium mineralisation on DR-3 is concentrated within a major east-west-trending channel, with the best-developed ore at the junctions of this channel with tributaries from the south. This is probably due to plant material settling out in the areas of reduced current velocities where opposing streams meet

    Cole, D.I.

    1979-06-01

    A study of the sedimentology of some uranium-bearing sandstones on the farm Ryst Kuil 351 was made in order to assess possible relationships between the mineralisation and the sedimentary facies and/or the palaeo-environment. Use was made of 6 vertical profiles, derived from horizontal traverses. 12 sedimentary facies were recognised according to grain-size and sedimentary structure. The transitions between these facies, as derived from the vertical profiles, were subjected to Markov analysis. Only 3 Markov-dependent transitions were derived, but several facies transitions and associations occurred with greater than random frequency. These, together with the vertical profiles, were used to interpret the palaeo-environmental succession. This succession is fluvial meandering and two sub-environments - channel and flood plain - were delineated according to the prevalence of sandstone or mudstone facies. The uranium-bearing sandstones occur in the lower part of a thick (29 - 46m) multistorey point bar sequence within the channel sub-environment. The mineralisation is associated with koffieklip and is restricted to two sedimentary facies - massive very fine-to-finegrained sandstone and horizontally bedded, very fine- to fine-grained sandstone. The mineralisation normally occurs near the bases of the point bars

    2013-09-01

    Full Text Available Estuarine mangroves give natural support to the protection of the riverbanks, due to their accumulative nature. To study this effect, it is necessary to measure sedimentation rates under estuarine mangroves. Sediment plays an important role in the storage and release of nutrient into the water column, the mineralization of organic carbon deposits by various kinds of microbes. In association with other parameters, the sediment is responsible for the variations in densities of majority of benthic organisms. Regular monthly collections of bottom water and sediment were made for a period thirteen months from January 2008 and January 2009 at five different study sites using the motorized outrigger canoe. The present investigation encompassed collection of data pertaining to various aspects of sedimentology. Sediment temperature varied from 25.100c to 30.450c. The pH ranged between 6.18 to 8.30. Organic carbon Varied between 2.06 to 29.45%, moisture content varied from 20.10% to 41.88. Values of interstitial water content is varied between 1.60% to 30.95%. Wide variation in the percentage composition of sand (28.45% to 80.10%, silt (12.78% to 54.28%, and clay (3.66% to 33.63% was observed.

    Full Text Available The study of glacial landforms and deposits is important, as it isdifficult to observe processes under modern glaciers and ice-sheets. Thus landscapes and sediments that are the product of present glaciation can give insight into processes that occurred during Pleistocene times. This study investigates the genesis of little ice age glacial landforms present in Portage Glacier, South-Central Alaska. The present day moraine morphology and sedimentology in Portage Glacier valley reveals the presence of two types of till and moraines. The clast-rich sandy diamicton present on the 1852 moraine is interpreted to be a basal till indicating this feature is a pushmoraine representing an advance or a standstill position of Portage Glacier in 1852. The moderately sorted gray sandy boulder gravel present on the 1900 and 1922 moraines is interpreted to be an ice-marginal deposit (ablation till with a mixture of supraglacial and glaciofluvial sediments deposited by slumping and stream sortingprocesses. All of these features are interpreted to be ablation moraines representing glacier retreat and moraine building in 1900 and1922.

    1982-08-01

    The sedimentology, mineralogy and geochemistry of the Mooifontein deposit, which is situated north-west of Edenburg, Orange Free State, has been investigated. The orebody is located stratigraphically in the Adelaide Subgroup of the Karoo Sequence. Palaeocurrent and geological sections afford a picture of a fan-shaped distributary system and together with features such as small-scale channeling, cyclical deposition and an upward coarsening cycle, suggest a lacustrine-delta model of formation. The rocks constituting the deposit are feldspathic greywackes and feldspathic silt- and mudstones and can be divided into five texturally distinguishable groups. The mineralised lenses of the Mooifontein deposit attain a thickness of 7 m which can be split into two or three zones. The average grade of 0,85 kg U 3 O 8 /t is lower than that of the southern Karoo deposits (1 kg U 3 O 8 /t). The shallow depth of the orebody makes it amenable to open-cast mining. Molybdenum concentrations in the deposit are too low to be of economic significance. The sediments have low copper, vanadium and arsenic contents and the above-average calcite content of 9% will result in high acid consumption should an acid leaching process be used for uranium recovery. Both calcite and fluorite are unrelated to the uranium mineralisation. The deposit as a whole appears to have been little affected by post-genetic processes with only minor redistribution of uranium and moderate oxidation of organic carbon and sulphides

    Full Text Available The Ratkovce 1 well, drilled in the Blatné depocenter of the northern Danube Basin penetrated the Miocene sedimentary record with a total thickness of 2000 m. Biostratigraphically, the NN4, NN5 and NN6 Zones of calcareous nannoplankton were documented; CPN7 and CPN8 foraminifer Zones (N9, 10, 11 of the global foraminiferal zonation; and MMi4a; MMi5 and MMi6 of the Mediterranean foraminiferal zonation were recognized. Sedimentology was based on description of well core material, and together with SP and RT logs, used to characterize paleoenvironmental conditions of the deposition. Five sedimentary facies were reconstructed: (1 fan-delta to onshore environment which developed during the Lower Badenian; (2 followed by the Lower Badenian proximal slope gravity currents sediments; (3 distal slope turbidites were deposited in the Lower and Upper Badenian; (4 at the very end of the Upper Badenian and during the Sarmatian a coastal plain of normal marine to brackish environment developed; (5 sedimentation finished with the Pannonian-Pliocene shallow lacustrine to alluvial plain deposits. The provenance analysis records that the sediment of the well-cores was derived from crystalline basement granitoides and gneisses and from the Permian to Lower Cretaceous sedimentary cover and nappe units of the Western Carpathians and the Eastern Alps. Moreover, the Lower Badenian volcanism was an important source of sediments in the lower part of the sequence.

    Detailed sedimentological and paleontological analyses were carried out on more than 13,000 m of core from ten boreholes in the Late Neogene sediments of the Pannonian Basin, Hungary. These data provide the basis for determining the character of high-order depositional cycles and their stacking patterns. In the Late Neogene sediments of the Pannonian Basin there are two third-order sequences: the Late Miocene and the Pliocene ones. The Miocene sequence shows a regressive, upward-coarsening trend. There are four distinguishable sedimentary units in this sequence: the basal transgressive, the lower aggradational, the progradational and the upper aggradational units. The Pliocene sequence is also of aggradational character. The progradation does not coincide in time in the wells within the basin. The character of the relative water-level curves is similar throughout the basin but shows only very faint similarity to the sea-level curve. Therefore, it is unlikely that eustasy played any significant role in the pattern of basin filling. Rather, the dominant controls were the rapidly changing basin subsidence and high sedimentation rates, together with possible climatic factors.

    The study area corresponds to the Nunchia syncline, which is located in the eastern foothills of the eastern cordillera of Colombia. This structure is bounded by the Yopal thrust to the east, and Guaicaramo thrust to the west. This syncline has mostly outcrops of Miocene units, which belong to the Carbonera (C1-C5), Leon and Guayabo formations. Here we use sedimentologic data, especially in the Guayabo Formation, in order to determine the influence of active tectonics during its deposition. Petrographic analyses of sandstones indicate the presence of components associated with upper Cretaceous - Paleocene formations in the eastern cordillera. Paleocurrent orientation shows a preferential trend towards the se during the deposition of most of the studied formations, with a reversal in flow direction towards the W-NW during the deposition of the middle Guayabo Formation preserved in the Nunchia syncline. The collected data allows establishing a structural evolution in the Nunchia syncline which was therefore active during most of the Miocene. This evolution appears to be continuous, although fragmentation of the geological record shows more specific periods of tectonic activity.

    For life-of-mine planning, as well as for short- and medium-term planning of grades and mine layouts, it is extremely important to have a clear understanding of the patterns followed by the distribution of gold and uranium within the mining area. This study is an attempt to reconcile the geostatistical approach to the determination of ore-shoot directions, via an analysis of the spatial distribution of gold and uranium values, with the sedimentological approach, which is based on the direct measurement of geological features. For the routine geostatistical estimation of ore reserves, the Hartebeestfontein gold mine was divided into ll sections. In each of these sections, the ore-shoot directions were calculated for gold and uranium from the anisotropies disclosed by geostatistical variogram analyses. This study presents a comparison of these results with those obtained from direct geological measurements of paleo-current directions. The results suggest that geological and geostatistical studies could be of significant mutual benefit [af

    Full Text Available The results of the detailed sedimentological study and bed-by-bed collecting of fossils from the Borschovo section exposing the upper Givetian–lower Frasnian boundary beds are discussed. The succession consists of sandstones alternating with argillaceous and clayey packages that contain vertebrate and plant remains in the upper part. The grain size, sedimentary structures and cross-bed orientation considerably differ in the Oredezh Beds and the Staritsa Beds. Fine- to coarse-grained cross-stratified sandstones of the Oredezh Beds most probably are fluvial deposits, whereas the sandstones of the Staritsa Beds yielding tidal structures that show variable directions of the cross-bedding were accumulated in a tidally influenced or even tidally dominated environment. The Oredezh Beds in the study area lack fossils; however, sedimentary features allow correlation with the Sietiņi Formation corresponding to the lower part of the Gauja Regional Stage. The age of the Staritsa Beds is defined based on the distribution of vertebrate taxa as corresponding to the Amata Regional Stage. Probably, the deposits from the Borschovo locality represent the most complete section of the Staritsa Beds, including its lowermost part. Rather good preservation of some thin and fragile fish bones, buried together with large-sized quartz grains, and wide taxonomical diversity, are characteristic of the Borschovo locality, which is not common for the vertebrate localities of the Main Devonian Field corresponding to the Amata Regional Stage.

    The Zackenberg River delta is located in northeast Greenland (74°30' N, 20°30' E) at the outlet of the Zackenberg fjord valley. The fjord-valley fill consists of a series of terraced deltaic deposits (ca. 2 km2) formed during relative sea-level (RSL) fall. We investigated the deposits using sedimentological and cryostratigraphic techniques together with optically stimulated luminescence (OSL) dating. We identify four facies associations in sections (4 to 22 m in height) exposed along the modern Zackenberg River and coast. Facies associations relate to (I) overriding glaciers, (II) retreating glaciers and quiescent glaciomarine conditions, (III) delta progradation in a fjord valley, and (IV) fluvial activity and niveo-aeolian processes. Pore, layered, and suspended cryofacies are identified in two 20 m deep ice-bonded sediment cores. The cryofacies distribution, together with low overall ground-ice content, indicates that permafrost is predominately epigenetic in these deposits. Fourteen OSL ages constrain the deposition of the cored deposits to between approximately 13 and 11 ka, immediately following deglaciation. The timing of permafrost aggradation was closely related to delta progradation and began following the subaerial exposure of the delta plain (ca. 11 ka). Our results reveal information concerning the interplay between deglaciation, RSL change, sedimentation, permafrost aggradation, and the timing of these events. These findings have implications for the timing and mode of permafrost aggradation in other fjord valleys in northeast Greenland.

    2002-01-01

    Detail mapping of the Lokoja Formation consisting predominantly of sandstones exposed along Okene-Abuja highway near the confluence of Rivers Niger and Benue in the southern Bida Basin was undertaken in an attempt to reconstruct their depositional history. The analyses of the lithofacies characteristics, pebble morphogenesis and ichnofossil content of the Lokoja sandstones in the study area reveal their depositional environments which evolved from alluvial fans through braided stream into nearshore shallow marine conditions. The massive, immature, matrix to grain supported conglomerate subfacies can be interpreted as debris flow. The conglomeratic sandstone facies (massive, cross stratified and graded subfacies) reflect deposits of deep braided channels. The bioturbated and herringbone cross stratified conglomeratic sandstones indicate shallowing to marginal marine environments. The fine to medium grained sandstones, siltstones and claystones are interpreted as channel bars and floodplain deposits.Results of pebble morphogenesis analysis indicate predominance of fluvial processes. Minor high energy (probably beach) condition is indicated by some individual clasts from the conglomeratic sandstone facies with sphericity and OP index values less that 0.66 and -1.5 respectively.The study is significant because it represents the first sedimentological evidence of influence of shallow marine in the development of Lokoja sandstones during Campanian-Maastrichtian times

    Observed exhumed Pleistocene river channel conglomerates now standing as ridges, and inland sabkha sedimentological structural phenomena from Oman, are discussed. Their significance as tools in the interpretation of similar palaeogeological environments is considered. Correlation with similar channel fills elsewhere in Arabia and Iran indicates aggradation as having occurred between 35,000 to 7000 y BP and suggests that this was principally by sustained flow during pluvial phases accompanying the last global glaciation, (at least in this part of the Middle East). Elevations of the now inverted channels above their deflated desert surroundings are used for calculating deflation rates, and reservoir porosity-permeability characteristics of similar ancient deposits are considered. Additional and new data on halite crust structures from the Umm-as-Samim inland sabkha are presented mainly in photographs backed by factural data which are commented upon; sabkha formation probably commenced about 4500 y BP. The preservation of similar origin halite deposits in the stratigraphic record is briefly discussed. This note is intended to augment data on desert environments that appear to have either had passing mention, or simply recording without assessment of their significance as tools or indicators in the interpretation of similar palaeogeological environments. It is the hope that the observations recorded here will stimulate further work on these and other Holocene phenomena in the region concerned and also elsewhere, together with dissemination of results, so that their implications to various aspects of applied geology can be better evaluated and understood. 9 figures.

    Brynard, H.J.; Le Roux, J.P.

    1982-08-01

    A sedimentological and mineralogical investigation was carried out on the River deposit discovered by Mining Corporation (Pty) Ltd in Qwa-Qwa, 15 km south-west of Phuthaditjhaba. The orebody is located in fluvial sandstones of the upper Elliot Formation. Palaeocurrent directions reflect a low- to very low-sinuosity river system with a vector mean azimuth towards 062 degrees. A study of sedimentary structures and grain sizes in cliff sections was supplemented by an analysis of borehole logs, which disclosed the sedimentary environment as a braided river of the Donjek type. Uranium mineralisation at the River prospect is unusually thick, averaging almost 2 m, but lower overall grade than the southern Karoo deposits. Almost 30% of the uranium is present in mudstone and siltstone, and the fact that mineralisation in the sandstone is of similar grade and thickness to that of the former two lithological types suggests that grain sizes played a minor role in the dispersion of the ore fluids. The rocks are mainly of three types, viz. lithic graaywackes, feldspathic graywackes and siltstones, of which calcareous and carbonaceous varieties of the former two occur. Uranium mineralisation is associated mainly with organic carbon which occurs in various modes. A small amount of uranium is present as secondary beta-uranophane which occurs interstitially to detrital grains and in the pores of the clayey matrix and lithic fragments. Uranium is the only trace element of economic significance

    In August 2015, scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center collected 11 push cores from the marshes of Dauphin Island and Little Dauphin Island, Alabama. Sample site environments included high marshes, low salt marshes, and salt flats, and varied in distance from the shoreline. The sampling efforts were part of a larger study to assess the feasibility and sustainability of proposed restoration efforts for Dauphin Island, Alabama, and to identify trends in shoreline erosion and accretion. The data presented in this publication can provide a basis for assessing organic and inorganic sediment accumulation rates and temporal changes in accumulation rates over multiple decades at multiple locations across the island. This study was funded by the National Fish and Wildlife Foundation, via the Gulf Environmental Benefit Fund. This report serves as an archive for the sedimentological and geochemical data derived from the marsh cores. Downloadable data are available and include Microsoft Excel spreadsheets (.xlsx), comma-separated values (.csv) text files, JPEG files, and formal Federal Geographic Data Committee metadata in a U.S. Geological Survey data release.

    2013-01-01

    Climate change is likely to cause serious market failures, and carbon trading as a market instrument can help correct its negative impacts. The global carbon markets established to combat climate change include regulatory and voluntary markets. Turkey cannot utilise regulatory carbon markets under the Kyoto Protocol. As a result of her unique position in the UNFCCC, some offsetting projects in Turkey have benefitted only voluntary emission trading for the reduction of GHG emissions. Due to on-going climate change negotiation under the UNFCCC, it seems that Turkey will not use the current regulatory carbon markets. Thus, Turkey should promote the use of and participation in voluntary carbon markets. In this article, emission reduction potential via energy efficiency, renewable energy and solid waste management, and corresponding offsetting of credits with their estimated prices is investigated for the period between 2013 and 2020. The emission reduction potential for energy efficiency, renewable energy and solid waste management projects are estimated at 403, 312 and 356 million tons of CO 2 equivalent emissions respectively, totalling 1,071 million tons of CO 2 equivalent. The total revenue of the carbon certificates are estimated in the range of 19,775–33,386 million US Dollars for the same period. -- Highlights: •Turkey has 1,071 million tons GHG emission reduction in three sectors for 2013–2020. •Turkey can only use voluntary emission trading for reduction of GHGs. •Total revenue estimation could be between 19,775 and 33,386 million US Dollars. •Turkey's economy and emissions have been rapidly growing. •Turkey can more easily reduce its emission by using voluntary emission trading

    2010-07-01

    Full Text Available Global sourcing is to source from the global market for goods and services across national boundaries in order to take advantage of the global efficiencies in the delivery of a product or service. Such efficiencies are consists of low cost skilled labor, low cost raw materials and other economic factors like tax breaks and deductions as well as low trade tariffs. When we assess the case regarding to Turkey, global sourcing is an effective device for some firms. The domestic firms in Turkey at various industries are inclined to global source finished or intermediate goods from the world markets, finish the production process in Turkey and export. Eventually, on the one hand the export volume of Turkey increases, but on the other hand the import of a considerable volume of finished or intermediate goods bring about a negative trade balance and loss of jobs in Turkey. Therefore, the objective of this study is to assess the concept of global sourcing transactions on Turkey resting on comprehensive publications.

  18. Oil and gas market developments in Turkey

    Kaygusuz, K.

    2003-01-01

    Turkey's strategic location makes it a natural 'energy bridge' between major oil and gas producing areas in the Middle East and Caspian Sea regions on one hand and consumer markets in Europe on the other. Oil consumption has increased in recent years in Turkey, and this trend is expected to continue, with growth of 2-3% annually in coming years. The annual oil consumption of the country is around 31.3 million tons, while 83% of total consumption is supplied from imports and only 17% is supplied from indigenous production. Oil provides around 43% of Turkey's total energy requirements, but its share is declining (as the share of natural gas rises). On the other hand, due to diversification efforts of energy sources, use of natural gas was newly introduced into the Turkish economy in 1987 and has been growing rapidly. Turkey's natural gas reserves seem limited and current gas production in the country meets 2.8% of domestic consumption requirements. The annual natural gas consumption of Turkey is around 14.7 billion m 3 and is assumed to increase by 12% per annum. Turkish natural gas use is projected to increase dramatically in coming years, with the prime consumers expected to be industry and power plants. Turkey has chosen natural gas as the preferred fuel for the massive amount of new power plant capacity to be added in coming years. (Author)

    This report presented some quick facts about oil and gas pipelines in Turkey and presented opportunities for trade. The key players and customers in the oil and gas sector were described along with an export check list. Turkey is looking into becoming an energy bridge between oil and gas producing countries in the Middle East, Central Asia and Europe. The oil and gas sectors are dominated by the Turkish Petroleum Corporation, a public enterprise dealing with exploration and production, and the State Pipeline Corporation which deals with energy transmission. They are also the key buyers of oil and gas equipment in Turkey. There are several pipelines connecting countries bordering the Caspian Sea. Opportunities exist in the areas of engineering consulting as well as contracting services for oil and gas pipeline transmission and distribution. Other opportunities lie in the area of pipeline construction, rehabilitation, materials, equipment, installation, and supervisory control and data acquisition (SCADA) systems. Currently, the major players are suppliers from Italy, Germany, France, United States and Japan. Turkey has no trade barriers and imported equipment and materials are not subjected to any restriction. The oil and gas market in Turkey expected in increase by an average annual growth rate of 15 per cent from 2001 to 2003. A brief description of pipeline projects in Turkey was presented in this report along with a list of key contacts and support services. 25 refs., 1 append

    2013-01-01

    Recently, the importance of renewable energy sources has increased significantly as climate change has become an important long term threat to global ecosystems and the world economy. In the face of increased concern about climate change and high fossil fuel costs together with a reduction in the primary energy sources such as oil, natural gas and coal, alternative energy sources (renewables) are increasingly needed to respond to the threat of climate change and growing energy demand in the world. Recent developments in Turkey, such as the liberalization of the electricity market and improvements in the renewable legislations, have accelerated the growth process and investment opportunities in the field of renewable energy. Turkey′s naturally endowed potential for renewables, such as solar, geothermal and wind, also accompanied these developments and attracted world attention to this market. In Turkey, renewable energy sources have gained great importance in the last decades due to growing energy demand and incentive policies which foster the utilization of renewable energy sources. This study aims to explore the availability and potential of renewable energy sources in Turkey and discuss the government policies and economic aspects. - highlights: • Turkey′s potential for renewable energy has attracted world attention. • Turkey has specific energy objectives in promoting renewable energy. • This paper evaluates recent incentives for renewable energy in Turkey. • Incentives in Turkey have led to more investment in renewable energy generation

    Solar energy is considered a key source for the future, not only for Turkey, also for all of the world. Therefore the development and usage of solar energy technologies are increasingly becoming vital for sustainable economic development. The main objective of this study is investigating the employment effects of solar energy industry in Turkey. Some independent reports and studies, which analyze the economic and employment impacts of solar energy industry in the world have been reviewed. A wide range of methods have been used in those studies in order to calculate and to predict the employment effects. Using the capacity targets of the photovoltaic (PV) and concentrated solar power (CSP) plants in the solar Roadmap of Turkey, the prediction of the direct and indirect employment impacts to Turkey's economy is possible. As a result, solar energy in Turkey would be the primary source of energy demand and would have a big employment effects on the economics. That can only be achieved with the support of governmental feed-in tariff policies of solar energy and by increasing research-development funds. - Highlights: → The objective of the study, is investigating employment effects of solar energy. → Using the capacity targets of the PV and CSP plants in solar roadmap of Turkey. → Direct employment has been calculated by constructing of the solar power plant. → If multiplier effect is accepted as 2, total employment will be doubled. → Validity of the figures depends on the government's policies.

    2015-01-01

    Turkey has a great potential regarding thorium resources. Thorium exploration activities have been done in the past mainly by state organizations for determining the thorium resources in Turkey. Thorium occurs as complex mineral together with barite, fluorite and rare earth elements (REE). The increase in global demand for REE creates the opportunity for REE production which will also produce thorium as a by-product. The development of nuclear energy program in Turkey provides the stimulus for research and development activities in nuclear technologies. The final declaration of the workshop emphasizes the importance of thorium reserves in Turkey and the necessity for thorium exploration and development activities in order to determine the feasibility of thorium mining and fuel cycle in Turkey. These activities should be conducted together with the development of technologies for separation of these complex minerals and purification of thorium, REE and other minerals to be utilized as commercial products. There are advanced academic research studies on thorium fuel cycle which should be supported by the industry in order to commercialize the results of these studies. Turkey should be integrated to international R and D activities on ADS which is expected to commercialize on medium term. The legislative framework should be developed in order to provide the industrial baseline for nuclear technologies independent from nuclear regulatory activities

    2010-01-01

    Main electrical energy sources of Turkey are thermal and hydraulic. Most of the thermal sources are derived from natural gas. Turkey imports natural gas; therefore, decreasing usage of natural gas is very important for both economical and environmental aspects. Because of disadvantages of fossil fuels, renewable energy sources are getting importance for sustainable energy development and environmental protection. Among the renewable sources, Turkey has very high wind energy potential. The estimated wind power capacity of Turkey is about 83,000 MW while only 10,000 MW of it seems to be economically feasible to use. Start 2009, the total installed wind power capacity of Turkey was only 4.3% of its total economical wind power potential (433 MW). However, the strong development of wind energy in Turkey is expected to continue in the coming years. In this study, Turkey's installed electric power capacity, electric energy production is investigated and also Turkey current wind energy status is examined. (author)

    Full Text Available Thalassemia and abnormal haemoglobins are a serious health problem in Turkey. Very important steps for toward preventing thalassemia have been taken in Turkey by Ministry of Health (MOH, Turkish National Haemoglobinopathy Council (TNHC and Thalassemia Federation of Turkey (TFT since 2000. In 1993, a law was issued called Fight Against Hereditary Blood Disease especially for thalassemia and haemoglobinopathies. The law commends to prevent haemoglobinopathies and to treat all patients with haemoglobinopathy and thalassemia. A pilot project was started and centres were created in the MOH Hospitals in the southern provinces of Turkey. In 2000, TNHC was installed to combine all centres, foundations, and associations into one organization controlled by the MOH. In 2001, the MOH and the TNHC made an inventory of all recorded patients with thalassemia and abnormal hemoglobins in Turkey, registering at least 4513 patients. In 2002, written regulations for the Fight Against Hereditary Blood Disease were published. MOH and TNHC selected 33 provinces situated in the Thrace, Marmara, Aegean, Mediterranean and South Eastern regions with high birth prevalence of severe haemoglobinopathies. In 2003, the haemoglobinopathy scientific committee was set-up, a guidebook was published and a national Hemoglobinopaty Prevention Program (HPP was started in these high risk provinces . This program is running in these provinces successfully. In 2005, TFT was established as a secular society organization instead of TNHC. In 2007, National Thalassemia Prevention Campaign (NTPC was organized for public education by TFT. This campaign contributed very important supporting to HPP in Turkey, because totally 62.682 people such as health workers, students, teachers, demarches, religion officers and the other many people were educated for preventing thalassemia and haemoglobinopathies. In 2009, National Thalassemia Education Seminars (NTES for health personnel have been planned in

    2015-04-01

    Modern ocean sediments serve as the interface between the biosphere and the geosphere, play a key role in biogeochemical cycles and provide a window on how contemporary processes are written into the sedimentary record. Research over past decades has resulted in a wealth of information on the content and composition of organic matter in marine sediments, with ever-more sophisticated techniques continuing to yield information of greater detail and as an accelerating pace. However, there has been no attempt to synthesize this wealth of information. We are establishing a new database that incorporates information relevant to local, regional and global-scale assessment of the content, source and fate of organic materials accumulating in contemporary marine sediments. In the MOSAIC (Modern Ocean Sediment Archive and Inventory of Carbon) database, particular emphasis is placed on molecular and isotopic information, coupled with relevant contextual information (e.g., sedimentological properties) relevant to elucidating factors that influence the efficiency and nature of organic matter burial. The main features of MOSAIC include: (i) Emphasis on continental margin sediments as major loci of carbon burial, and as the interface between terrestrial and oceanic realms; (ii) Bulk to molecular-level organic geochemical properties and parameters, including concentration and isotopic compositions; (iii) Inclusion of extensive contextual data regarding the depositional setting, in particular with respect to sedimentological and redox characteristics. The ultimate goal is to create an open-access instrument, available on the web, to be utilized for research and education by the international community who can both contribute to, and interrogate the database. The submission will be accomplished by means of a pre-configured table available on the MOSAIC webpage. The information on the filled tables will be checked and eventually imported, via the Structural Query Language (SQL), into

    In this report, the activity concentrations of natural and artificial radionuclides and gross alpha/beta activities measured in the environmental and food samples provided from Turkey's seven geographical regions within the environmental radioactivity monitoring program in 2008 as well radon activity concentrations measured in dwellings, and absorbed gamma dose rates in air obtained by means of car-borne measurement system (Mobysis) are presented. The activity concentrations of the natural and artificial radionuclides and gross alpha/beta activities in the samples were measured by using the gamma spectrometry, the alpha spectrometry, the liquid scintillation counter and gross alpha/beta counting system. The mean activity concentrations of 2 26Ra, 2 32Th and 4 0K in the analyzed surface samples are to be found as 26.0±0.9 Bq kg - 1, 31.6±1.2 Bq kg - 1 and438.5tively, while the mean activity concentration of the fission product 1 37Cs is to be found as 10.5±1.0 Bq kg - 1. The mean absorbed gamma dose rate in outdoor caused from the external exposure from natural radionuclides in soil samples and the corresponding annual effective dose are evaluated as 49.4 nGy h - 1 and 0.06 mSv y - 1, repectively. The activitity concentrations of 2 38U, 2 32Th and 2 26Ra in the analyzed food samples are lowere than the Minimum Detectable Activity (MDA) while 1 34Cs radionuclide is not observed. The mean value of the activity concentration of 4 0K measured in food samples in seven categories is found as 129.8±11.3 Bq kg - 1. While the values of the activity concentration of 1 37Cs are below the MDA except mushroom and hazelnut. The mean activity concentration of 1 37Cs and 9 0Sr radionuclides measured in the milk samples is 0.61 Bq L - 1 and 0.05 Bq L - 1, respectively. These values are lower than the limit value specified for foods subjected to control based on the regulation of the EU 737/90/EC.

    The Cambro-Permian Wajid Group, SW Saudi Arabia, is the main groundwater aquifer in Wadi Al-Dawasir and Najran areas. In addition, it has a reservoir potentiality for oil and natural gas in Rub' Al-Khali Basin. Wajid Group divided into four formations, ascending Dibsiyah, Sanamah, Khussyayan and Juwayl. They are mainly sandstone and exposed in an area extend from Wadi Al-Dawasir southward to Najran city and deposited within fluvial, shallow marine and glacial environments. This study aims to investigate the sedimentological and stratigraphic controls on the distribution of natural fractures within Wajid Group outcrops. A scanline sampling method was used to study the natural fracture network within Wajid Group outcrops, where the natural fractures were measured and characterized in 12 locations. Four regional natural fracture sets were observed with mean strikes of 050o, 075o, 345o, and 320o. Seven lithofacies characterized the Wajid Group at these locations and include fine-grained sandstone, coarse to pebbly sandstone, cross-bedded sandstone, massive sandstone, bioturbated sandstone, conglomerate sandstone, and conglomerate lithofacies. We found that the fine-grained and small scale cross-bedded sandstones lithofacies are characterized by high fracture intensity. In contrast, the coarse-grained sandstone and conglomerate lithofacies have low fracture intensity. Therefore, the relative fracture intensity and spacing of natural fractures within Wajid Group in the subsurface can be predicted by using the lithofacies and their depositional environments. In terms of stratigraphy, we found that the bed thickness and the stratigraphic architecture are the main controls on fractures intensity. The outcomes of this study can help to understand and predict the natural fracture distribution within the subsurface fractured sandstone hosting groundwater and hydrocarbon in Wajid and Rub' Al-Khali Basins. Hence, the finding of this study might help to explore and develop the

    During the Miocene the Moesian Platform (southern Romania and northern Bulgaria) had a complicated flexural behavior due to the mobility of the nearby orogens. The different behavior induced varying sediment charges, sediment distribution and sediment types. The northern part of the study area (on which the Dacian Basin is overlaid) is characterized by siliciclastic units with dominantly deep facieses, while the southern part is characterized by carbonate production in shallower basin waters. Since the Miocene, the Dacian and Black Sea basins have been highly sensitive to fluctuations in the hydrological cycle. To establish the dynamic evolution of the basin and the climate variations during the Miocene, we have sampled both northern and southern margins of the basin. To discriminate between the tectonic imprint and the eustatic influence over the sedimentation rate we have chosen a multidisciplinary approach including sedimentology, tectonics and organic geochemistry based reconstructions. The sedimentary succession is interrupted by few unconformities correspondent with the main phases of orogeny (in the Carpathian Foredeep) while the southern part seems to have been exposed more often expressed in the geological record by a higher number of unconformities and paleo-soils levels. The n-alkanes distribution recovered from the lipids extracted from the sedimentary rocks indicates a mixture of terrestrial and marine input in the northern, Romanian, closer to Carpathians, part of the Dacian Basin. Surprisingly, the southern, Bulgarian side, showed a more predominant terrestrial input (with higher contribution of the long chain n-alkanes) at least for the Sarmatian (arround 10 Ma). The estimated paleotemperatures based on branched GDGT's indicate much warmer conditions than present day, up to a value of 20 C mean annual temperatures. We will further investigate the paleoenvironmental changes during the latest Miocene of the Dacian basin, using the biomarker approach

    We have used a reservoir gridblock-sized outcrop (10m by 100m) of fluvio-deltaic sandstones to evaluate the importance of internal heterogeneity for a hypothetical waterflood displacement process. Using a dataset based on probe permeameter measurements taken from two vertical transacts representing {open_quotes}wells{close_quotes} (5cm sampling) and one {open_quotes}core{close_quotes} sample (exhaustive 1mm-spaced sampling), we evaluate the permeability variability at different lengthscales, the correlation characteristics (structure of the variogram, function), and larger-scale trends. We then relate these statistical measures to the sedimentology. We show how the sediment architecture influences the effective tensor permeability at the lamina and bed scale, and then calculate the effective relative permeability functions for a waterflood. We compare the degree of oil recovery from the formation: (a) using averaged borehole data and no geological structure, and (b) modelling the sediment architecture of the interwell volume using mixed stochastic/deterministic methods. We find that the sediment architecture has an important effect on flow performance, mainly due to bedscale capillary trapping and a consequent reduction in the effective oil mobility. The predicted oil recovery differs by 18% when these small-scale effects are included in the model. Traditional reservoir engineering methods, using averages permeability values, only prove acceptable in high-permeability and low-heterogeneity zones. The main outstanding challenge, represented by this illustration of sub-gridblock scale heterogeneity, is how to capture the relevant geological structure along with the inherent geo-statistical variability. An approach to this problem is proposed.

    A common break was recognized in four Lake Superior strandplain sequences using geomorphic and sedimentologic characteristics. Strandplains were divided into lakeward and landward sets of beach ridges using aerial photographs and topographic surveys to identify similar surficial features and core data to identify similar subsurface features. Cross-strandplain, elevation-trend changes from a lowering towards the lake in the landward set of beach ridges to a rise or reduction of slope towards the lake in the lakeward set of beach ridges indicates that the break is associated with an outlet change for Lake Superior. Correlation of this break between study sites and age model results for the strandplain sequences suggest that the outlet change occurred sometime after about 2,400 calendar years ago (after the Algoma phase). Age model results from one site (Grand Traverse Bay) suggest an alternate age closer to about 1,200 calendar years ago but age models need to be investigated further. The landward part of the strandplain was deposited when water levels were common in all three upper Great Lakes basins (Superior, Huron, and Michigan) and drained through the Port Huron/Sarnia outlet. The lakeward part was deposited after the Sault outlet started to help regulate water levels in the Lake Superior basin. The landward beach ridges are commonly better defined and continuous across the embayments, more numerous, larger in relief, wider, have greater vegetation density, and intervening swales contain more standing water and peat than the lakeward set. Changes in drainage patterns, foreshore sediment thickness and grain size help in identifying the break between sets in the strandplain sequences. Investigation of these breaks may help identify possible gaps in the record or missing ridges in strandplain sequences that may not be apparent when viewing age distributions and may justify the need for multiple age and glacial isostatic adjustment models. ?? 2006 Springer Science

    Full Text Available Sedimentological and scanning electron microscopic analyses of some shallow reservoir tar sand samples in parts of Southwestern Nigeria were carried out with the aim of characterizing the reservoir properties in relation to bitumen saturation and recovery efficiency. The production of impregnated tar from the sands requires the reservoir to be of good quality. A total of thirty samples were collected at different localities within the tar sand belt (ten out of these samples were selected for various reservoir quality analyses based on their textural homogeneity. The result of particle size distribution study showed that bulk of the sands is medium – coarse grained and moderately sorted. The grain morphologies are of low to high sphericity with shapes generally sub-angular to sub-rounded, implying that the sands have undergone a fairly long transportation history with depositional energy having a moderate to high velocity. The quartz content was made up of about 96% of the total mineralogical components; the sediments of the Afowo Formation can be described to be mineralogically and texturally stable. The result of the scanning electron microscopy (SEM analysis revealed that the oil sands contained minerals which had been precipitated and occurred as pore filling cement; these minerals include sheet kaolinite, block kaolinite, vermiform kaolinite, pyrite crystals and quartz. The SEM images also showed micro-pores ranging from 0.057µm to 0.446µm and fractures. The study showed that the clay minerals contained in the Afowo reservoir rocks were mainly kaolinite. Kaoline unlike some other clays (e.g Montimorillonite does not swell with water, hence it is not expected to have any negative effects on the reservoir quality, especially during enhanced oil recovery operations.

    Full Text Available The Zackenberg River delta is located in northeast Greenland (74°30′ N, 20°30′ E at the outlet of the Zackenberg fjord valley. The fjord-valley fill consists of a series of terraced deltaic deposits (ca. 2 km2 formed during relative sea-level (RSL fall. We investigated the deposits using sedimentological and cryostratigraphic techniques together with optically stimulated luminescence (OSL dating. We identify four facies associations in sections (4 to 22 m in height exposed along the modern Zackenberg River and coast. Facies associations relate to (I overriding glaciers, (II retreating glaciers and quiescent glaciomarine conditions, (III delta progradation in a fjord valley, and (IV fluvial activity and niveo-aeolian processes. Pore, layered, and suspended cryofacies are identified in two 20 m deep ice-bonded sediment cores. The cryofacies distribution, together with low overall ground-ice content, indicates that permafrost is predominately epigenetic in these deposits. Fourteen OSL ages constrain the deposition of the cored deposits to between approximately 13 and 11 ka, immediately following deglaciation. The timing of permafrost aggradation was closely related to delta progradation and began following the subaerial exposure of the delta plain (ca. 11 ka. Our results reveal information concerning the interplay between deglaciation, RSL change, sedimentation, permafrost aggradation, and the timing of these events. These findings have implications for the timing and mode of permafrost aggradation in other fjord valleys in northeast Greenland.

    The Bir Sahara area contains a remarkable record of Middle and Late Pleistocene hydrologic and environmental conditions for Saharan North Africa, based on lithostratigraphic and sedimentologic evidence from basin-fill deposits. Some of the deposits contain Lower Paleolithic (Acheulean) or Middle Paleolithic artifacts that help to constrain their age, since Acheulian artifacts are assigned to the Middle Pleistocene, while Middle Paleolithic artifacts are limited to either the Middle or Late Pleistocene. Locality BS-14 is in the southern part of Bir Sahara, while localities E-88-15, E-88-2, BS-13, and BS-16 are situated in the south-central part of the deflational basin, closer to the present-day water-hole. Lowered groundwater conditions during arid intervals resulted in erosional topographic basins. These deflational basins were later filled with sediments associated with wetter hydrologic conditions. The oldest studied sedimentary sequence in the Bir Sahara depression (BS-14) contains in situ Acheulian artifacts. Acheulian handaxes are found in sands underlying carbonates that are interpreted as evidence of spring-fed pond and marsh environments during a Middle Pleistocene wet interval. At the E-88-15 locality, the stratigraphic sequence documents deposition in a possible perennial pond or small lake that varied in extent and depth and is associated with Middle Paleolithic artifacts. At E-88-12 and BS-13, lateral and vertical variations in the lithofacies of the basin-fill sediments provide additional records of changing hydrologic conditions during the Late Pleistocene. These hydrologic conditions appear to reflect variations in water-table levels related to groundwater recharge and, at times, local rains.

  15. Sedimentology and chemostratigraphy of a Valanginian carbonate succession from the Baja Guajira Basin, northern Colombia

    Directory of Open Access Journals (Sweden)

    Juan Carlos Silva-Tamayo

    Full Text Available ABSTRACT: The Kesima Member of the Palanz Formation constitutes the first record of Cretaceous marine sedimentation along the Baja Guajira Basin, northern Colombia. Sedimentologic and petrographic analyses suggest a deposition along a coral reef dominated rimmed carbonate platform. 87Sr/86Sr values between 0.707350 and 0.707400 suggest a Valanginian (136 - 132 Ma depositional age for the Kesima Member. A positive anomaly on the δ13C values of ~2.2‰ suggests that this rimmed carbonate platform registered the Valanginian Weissert oceanic anoxic event. Although the Weissert oceanic anoxic event resulted on a major drowning of the Circum Tethyan carbonate platforms, it seems to have not affected those from the Circum Caribbean, where several shallow marine carbonate platform successions crop out. The Kesima Member displays a change from an organically produced carbonate factory into an inorganically produced, ooids dominated, carbonate factory during the peak of the Weissert event δ13C anomaly. This change in the carbonate factory, which may represent a major perturbation of the marine carbonate budget along tropical settings during the Weissert event, coincides with a major decrease in global sea level. Finally, the age of the Kesima Member is considerably older than that of other Cretaceous carbonate successions cropping out in other northern South America sedimentary basins (i.e. Perija-Merida, Cesar-Rancheria. Differences in the timing of the Cretaceous marine incursion along northern South America, together with the differences in the Triassic-Jurassic stratigraphy of several sedimentary basins in northern South America, suggest that the Baja Guajira and Maracaibo basins remained as an isolated tectonic block separated from northern South America after the breakup of Pangea.

  16. The sedimentology of uranium-bearing sandstones on the farm Kaffersfontein 328, Beaufort West area

    1979-10-01

    The sedimentology of uranium-bearing sandstones on the farm Kaffersfontein 328 was studied by use of 23 vertical profiles measured across and adjacent to 3 mineralised deposits. The profiles consist of 18 field sections and 5 borehole logs. The vertical profiles basically consist of a succession of sedimentary facies. A total of 18 facies were recognised within the fluvial sandstone sequence according to the criteria of grain-size and sedimentary structures. Transitions between the facies were subjected to a Markov chain analysis in order to delineate Markov-dependent transitions. Uranium mineralisation coincides with areas of thicker sandstone, usually where channel over-deepening has taken place. It always occurs above the base of a channel, which often marks the base of the fluvial sandstone sequence. Irregularities in the base of the channel probably caused interruptions to the flow of uraniferous solutions and allowed sufficient time for the precipitation of the uranium. Carbonaceous debris is always associated with the mineralisation and most likely acted as an indirect reductant for the precipitation of uranium from solution. The direct reductant was most probably H 2 S produced by anaerobic bacteria acting on the carbonaceous debris. The mineralisation is confined to the coarser-grained sedimentary facies, which suggests that permeability was an important control on the mineralisation. These facies probably acted as suitable aquifers for the transport of uraniferous solutions. Horizontally bedded sandstone facies comprises 41 per cent of the total cumulative thickness of mineralisation. This facies represents a higher stream power and may consequently contain more carbonaceous material derived from plants, which were eroded from upstream areas. The nature of the bedding may also have provided a more effective permeability zone for the transport of uraniferous solutions prior to precipitation of the uranium

    Full Text Available The work aims to investigate the geomorphological and sedimentological aspects of Union Glacier area (79°45’00’’S; 82°30’00’’W, southern sector of Ellsworth Mountains. Geomorphological cartography based on 15 m ASTER (2010 satellite imagery and field works were carried out during the Brazilian expedition (2011/2012 enabled the identification of morainic formations: ice-cored hummock moraines, supraglacial moraines, and recession moraines in the interior of the valleys. With the exception of the latter one, all types of moraines have been developed on the blue-ice areas. The evidence for paleo wet-based glacial conditions is reconstructed from a range of geomorphological record, including exposed abrasion marks, striations and glaciotectonic deformation. This type of deformation is represented by lee sides of oversteepening bedrock promontories which follow the tributaries of glaciers ice flow. Glacial sediments were collected from the moraines for granulometric and morphometric analyses. They show the prevalence of sandy gravel and sand texture, low quantity of fine fractions, and absence of attributes such as striated and faceted clasts, which indicate, on the other side, low-sediment transport capacity from the ice sheet bottom. It is inferred that the moraine debris are originated from local sources. Weathering action and constant katabatic winds are possibly the major agents of transport and alteration of the exposed sediments. The geomorphological features reveal an ancient thicker ice sheet, and sedimentary characteristics of the morainic formations reveal a latter thinner ice sheet in this sector of Ellsworth Mountains.

    2013-04-01

    Full Text Available Integration of sedimentologic and sequence stratigraphic interpretations of the Nkporo Group has provided the basis for a basin-wide framework for prediction of potential source, seal and reservoir rocks in the Anambra Basin, Nigeria. Lithofacies and biostratigraphic data show that the Nkporo Group in the Anambra Basin contains three main facies associations (fluvio-deltaic facies, estuarine central basin/shallow shelf facies and estuarine channel fill facies that determine the reservoir containers, flow units and seals. The units are arranged to form two stratigraphic sequences represented by the Nkporo Shale–Owelli Sandstone and Owelli Sandstone–Enugu Shale successions, respectively. The transgressive systems tract in each sequence comprises coarse-grained fluvio-deltaic sandstone and an overlying open marine black carbonaceous mud rock. The highstand systems tracts comprise delta front deposits with average porosity, permeability and net-to-gross values estimated in the ranges of 30%, 3000 md and 0.9, respectively. The fluvio-deltaic and delta front facies which are encased in organically rich estuarine central basin/shallow shelf mud rocks are likely the potential reservoirs. Trapping capacity is enhanced by the presence of several N–S trending normal faults, and other microstructures related to the post-Santonian tensional regime in the Benue. The new information presented in this paper on potential seal, source and reservoir lithofacies within the Nkporo Group should serve as a useful contribution to the geological modelling of reservoirs within the Late Cretaceous–Paleocene succession in the Anambra Basin.

    2017-04-01

    Full Text Available With oil and gas exploration transferring to deeper and more ancient marine strata, more researches have been conducted about the Meso–Neoproterozoic and Cambrian microbial carbonate rocks by petroleum geologists. The Cambrian deposits experienced the first transgression of the Paleozoic, with shallow marine facies depositing in most areas, which are favorable for different kinds of biological reproduction. The Lower Cambrian in Beijing area is lithologically dominated by purple red shales interbedded with limestones, the Middle Cambrian is mainly composed of thick oolitic limestones, and the Upper Cambrian consists of thin limestones and flat-pebble conglomerates. Two beds of microbial carbonate rocks were discovered in the Cambrian outcrops in the vicinity of Beijing. One is from the Zhangxia Formation of Middle Cambrian, and the other is from the Gushan Formation of Upper Cambrian. The microbialites are characterized by combination of multiple stromatolites forming different bioherms. The bioherms are mostly in oval shape and with different sizes, which are 3–4 m long, and 1–3 m high. The surrounding strata beneath the bioherms are oolitic limestones. A central core of flat-pebble conglomerates occurred within each bioherm. Wavy or columnar stromatolites grow on the basis of flat-pebble conglomerates, with dentate erosional surfaces. The bioherm carbonate rocks are interpreted as products from a deep ramp sedimentary environment where potential oil and gas reservoirs can be found. The analysis of sedimentological characteristics of bioherm carbonate rocks and its lithofacies palaeogeography has significant implication for petroleum exploration. Research on geological record of microbialites is beneficial to investigating the Earth evolution, biodiversity, palaeoenvironment and palaeoclimate change, as well as biological extinction event during geological transitions. It also gives warning to human beings of modern biological crisis.

    2013-07-01

    The tuff cone of El Golfo on the western coast of Lanzarote (Canary Islands) is a typical hydrovolcanic edifice. Along with other edifices of the same age, it was constructed along a fracture oriented NEE-SWW that coincides with the main structural trend of recent volcanism in this part of the island. We conducted a detailed stratigraphic study of the succession of deposits present in this tuff cone and here interpret them in light of the depositional processes and eruptive dynamics that we were able to infer. The eruptive sequence is represented by a succession of pyroclastic deposits, most of which were emplaced by flow, plus a number of air-fall deposits and ballistic blocks and bombs. We distinguished five different eruptive/depositional stages on the basis of differences in inferred current flow regimes and fragmentation efficiencies represented by the resulting deposits; the different stages may be related to variations in the explosive energy. Eight lithofacies were identified based on sedimentary discontinuities, grain size, components, variations in primary laminations and bedforms. The volcanic edifice was constructed very rapidly around the vent, and this is inferred to have controlled the amount of water that was able to enter the eruption conduit. The sedimentological characteristics of the deposits and the nature and distribution of palagonitic alteration suggest that most of the pyroclastic succession in El Golfo was deposited in a subaerial environment. This type of hydrovolcanic explosive activity is common in the coastal zones of Lanzarote and the other Canary Islands and is one of the main potential hazards that could threaten the human population of this archipelago. Detailed studies of these hydrovolcanic eruptions such as the one we present here can help volcanologists understand the hazards that this type of eruption can generate and provide essential information for undertaking risk assessment in similar volcanic environments.

    Full Text Available The article discusses some aspects of the relationship of the European Union and Turkey. Against the backdrop of the immigration crisis, that has gripped almost all countries in Europe, the EU states were forced to appeal to the Turkish Government for assistance. Europe requested to withhold part of the f refugees on the territory of Turkey. The EU promised financial support. The Government of RecepTayyip Erdogan linked problems with the issue of refugees entering the country in the EU. The author analyzes the possibility of positive promotion of the negotiation process on Turkey's EU membership. Focuses on the settlement of the Cyprus problem, as one of the three major political obstacles to Turkey in Europe. We are seeing a situation in which EU political circles are willing to exert pressure on the Cyprus conflict and to push for the signing of a formal treaty on the settlement of problem. Some progress in the negotiation process between the communities of Cyprus EU starts to participate in the negotiations on Cyprus, together with the United Nations. Creates good conditions for the settlement of the conflict. Such a way of resolving the long-standing territorial-community conflict creates much more new problems on the island. Obstacles to the integration of Turkey into the EU will become even more.

    Full Text Available While LGBT studies have been problematizing normative categories of sexuality primarily in Western cultures, the status of lesbian, gay, bisexual, and transgender (LGBT individuals in non-Western societies remains understudied. This study examines the political attitudes toward LGBT individuals in Turkish society and explores the experiences of transgender individuals. While Turkey holds a strong economic position among Western countries, the situation of sexual minorities lags behind international standards. This study explores two research questions. First, what is the Turkish government’s outlook for the LGBT community? Secondly, what kind of problems and challenges do trans-individuals experience in Turkey? This study first introduces a macro-level analysis of the politics of gender identity in Turkey by analyzing the debates of four deputies in the Turkish Parliament, each representing their parties’ disparate viewpoints. Secondly, a micro-level analysis of previously collected interviews with twenty-five trans-individuals are also examined that shed light on the difficulties of being a trans-individual in Turkey. The content analysis shows that trans-individuals experience physical, sexual, and emotional violence, in addition to experiencing discrimination in employment, housing, and healthcare. The findings of this micro-level analysis elucidate the continuous discrimination, inequality, and violence that these individuals experience, while the macro-level analysis portrays the state’s discriminatory policies toward LGBT individuals in Turkey.

    Full Text Available The purpose of this paper is twofold. First, drawing on data from the Household Labor Force Surveys over the period 2004-2013, it examines the determinants of the NEET (Not in Employment, Education or Training status for the Turkish youth. This is particularly important for Turkey as it has the highest NEET rate among the OECD countries. Second, it describes the movement of the youth across four states: education, employment, unemployment and inactivity. Probit results indicate that gender and educational attainment are key factors for explaining the NEET status. Findings also show that a greater number of household members that are in employment is associated with a lower likelihood of NEET. Transition analyses reveal that the state of inactivity remains highly persistent despite the substantial fall over the sample period. In addition, the rise in the persistence of education between 2007 and 2009 underlines the choice of the youth to stay in education in response to the fall in labor market prospects.

    1976-01-01

    In 1972-73 the Florida Power and Light Company (FPL) began operation of two nuclear reactors at Turkey Point on lower Biscayne Bay. One radioactive by-product resulting from the operation of the nuclear reactors, tritium, provides a unique opportunity to study transport and exchange processes on a local scale. Since the isotope in the form of water is not removed from the liquid effluent, it is discharged to the cooling canal system. By studying its residence time in the canal and the pathways by which it leaves the canals, knowledge of evaporative process, groundwater movement, and bay exchange with the ocean can be obtained. Preliminary results obtained from measurement of tritium levels, both in the canal system and in the surrounding environment are discussed. Waters in lower Biscayne Bay and Card and Barnes Sounds receive only a small portion of the total tritium produced by the nuclear plant. The dominating tritium loss most likely is through evaporation from the canals. The capability of measuring extremely low HTO levels allows the determination of the evaporation rate experimentally by measuring the tritium levels of air after having passed over the canals

    An area to the immediate east of Aberdeen (C.P.), banded in the north by the Rooiberge and to the east by the Sundays River, has been sedimentologically studied. A notable feature of the sediments investigated, is the presence of linear zones of increased sandstone. Some of the sediments also showed an exessive volume of argillaceous rocks. The sandstones cropping out in the Aberdeen District may be classified as lithic arkoses. Due to the manner in which the detrital grains appear to 'float' in calcite, an expansive growth mechanism is envisaged. This implies early crystallization of calcite, and emplacement of uranium

    Full Text Available Abstract: IMF has been created to make international cooperation on financial matters stronger and for solving the problems of balance of payment. However, the IMF formed policies in order to solve problems of balance of payment till the 1980s, expanded its effectiveness much more by controlling the structural adjustment programs after the 1980s, and undertook the role as an international lender of last resort on crises caused by globalization trends. In developing nations, foreign and domestic deficit occurred due to infrastructural causes that have created economic instabilities portrayed through inflation and unemployment. Especially foreign debt problems sourced by the foreign trade deficit transformed into an economic crisis for these countries. Many countries affected by such economic crisis applied to IMF and its Stabilization Program with the aim of providing economic stability in the hopes of recovering. The important thing here to point out is that the economic programs used by countries during their economic crisis are supported by the IMF in reality. In this situation Mexico and Argentina can be given as a good example. IMF has undertaken the same mission in Turkey with seven stabilization programs put in practice and nineteen Stand-By Arrangements between them. But IMF has failed many times in Turkey just like in many developing countries. This is because IMF did not take into consideration economic and social structure of countries in stabilization programs put in practice. Today, Turkey has reached to an important point from the way of its relationship with IMF; more clearly, Turkey is determined to achieve its future without IMF. Turkey-IMF relationship in the framework of stand-by agreements in the past half century of our economic and political history has come to an ending point. After a period of 51 years of intense relations, Turkey decided to determine its calculations of credit limit by the way of advantages and

    Tularemia is a zoonotic infection caused by Francisella tularensis. In the recent years tularemia has become a re-emerging infection in Turkey with epidemics and also sporadic cases. Transmission occurs most often through consumption of contaminated water and food, direct contact with animals and insect/ tick bites. In this study, we evaluated clinical features and laboratory findings of 35 tularemia cases diagnosed during two outbreaks that occurred in two different villages during two different periods in Konya (located in Central Anatolia), Turkey and five sporadic cases. In both outbreaks, first (index) cases were admitted to our outpatient clinic with the complaints of cervical lympadenopathy. After diagnosis of tularemia, an organized team visited the villages to search if more cases existed. For microbiological diagnosis, blood, throat and tonsil swabs and lymph node aspirate specimens were collected from the suspected cases. Diagnostic tests (culture, serology, molecular methods) for tularemia were performed in reference center, Refik Saydam National Public Health Agency. Drinking and potable water samples from those villages were also collected by provincial health authorities. The cases (n= 14) that belonged to the first epidemics were detected in February 2010 and cases (n= 21) of the second epidemics in November- December 2010; five cases were followed as sporadic. The mean age of the 40 patients (25 females, 15 males) was 37.6 (age range: 5-80 years; five of them were pediatric group) years. The most common complaints of patients were cervical mass (90%), sore throat (63%), chills (60%) and fever (58%). The most frequently detected clinical findings were enlarged lymph nodes (n= 34, 85%), followed by tonsillitis (20%), skin lesions (15%) and conjunctivitis (8%). Most of the patients (82.5%) had been misdignosed as acute tonsillitis, suppurative lymphadenitis, tuberculous lymphadenitis and brucellosis, before their admission to our hospital and treated

    Full Text Available Background: Obesity is associated with reduced quality of life, development of serious chronic conditions such as heart disease and diabetes, increased medical care costs, and premature death. Environmental effects, especially feeding habits may cause hyperinsulinemia and obesity. A Healthy People 2010 objective is to reduce the proportion of adults who are obese to 15%. Materials and Methods: This cross-sectional study was conducted on 1647 persons in a sample representing Gaziantep, Turkey. Over the selected 329 houses, 310 houses were reached (94.2% and data about 1315 related persons was collected. The body mass index (BMI shows the relationship between the weight and the height of people, calculated by the ratio of mass by kg over the square value of height measure. In statistical analyses chi-square, student′s t -test and logistic regression analysis were used. Results: The mean BMI increased with time for both sex, whereas decreased for 60+ age group. The fastest increase for both sex was seen while transition from 18 year to 19-29 age groups occurred. Another increase in women was in 30-39 age group; BMI=25.08±4.39 in 19-29 ages whilst BMI=29.02±5.79 in 30-39 ages. The increases in both sex in other age groups were not as much as in this group. Conclusion: Obesity is not only a problem in the Gaziantep but is also a major health concern in Europe and other regions of the world. As an accepted method against obesity, life-style changes should be put into use from childhood supported in school and family life.

  15. Environmental radioactivity in Turkey, 2007

    International Nuclear Information System (INIS)

    2009-01-01

    In this report, the activity concentrations of natural and artificial radionuclides, gross alpha/beta activities and air gamma dose rates in the environmental and food samples provided from Turkey's seven geographical regions within the environmental radioactivity monitoring program in 2007 are presented. The activity concentrations of the natural ( 238 U, 232 Th, 2 26Ra, 4 :0K and 7 Be) and artificial ( 137 Cs, 134 Cs, 90 Sr, 238-239+240 Pu, 2 41Am) radionuclides and gross alpha/beta activities in the samples were measured by using the gamma spectrometry, the alpha spectrometry, the liquid scintillation counter and the gross alpha /beta counting system. Results show that 137 Cs and 9 0Sr radionuclides originating from the Chernobyl Nuclear Reactor accident in 1986 exist in some of samples even in low levels. The mean activity concentrations of 238 U, 232 Th, 226 Ra and 40 K in the studied surface soil samples were found as 32.1 Bq kg -1 , 35.0 Bq kg -1 , 29.0 Bq kg -1 and 446.7 Bq kg -1 , respectively, while the mean activity concentrations of the fission product 1 37Cs was found as 18.4 Bq kg -1 . While the activity concentrations of 238 U, 232 Th and 226 Ra in the analyzed food samples are lower than the minimum detectable activity (MDA), 134 Cs and 7 Be radionuclides are not observed. The mean activity concentrations of 137 Cs and 90 Sr radionuclides are 0.24 Bq L - 1 and 0.05 Bq L - 1, respectively. (Includes 4 tables and 7 figures)

  16. Biogeomorphological influence of slope processes and sedimentology on vascular talus vegetation in the southern Cascades, California

    2012-02-01

    The vascular vegetation of alpine talus slopes between 2035 and 3095 m altitude was studied at Lassen Volcanic National Park (California) in the Cascade Range. Taluses show a diverse flora, with 79 plant species; growth forms include coniferous trees, shrubs, suffrutices, herbs, graminoids, and ferns. Spatial patterns of plant distribution were studied along 40 point-intercept transects. Plant cover was low (0-32.7%) on all slopes, spatially variable, and showed no consistent trends. Sedimentological characteristics were determined by photosieving next to 1500 plants; this census indicated preferential plant growth on blocks and cobbles, with 43.2% and 23.3% of the plants growing on these stones, respectively; fewer specimens were rooted on pebbles (13%) or on stone-free gravel areas (20.5%). Growth forms displayed different substrate preferences: 92.5% of the shrubs and 83% of the suffrutices colonized blocks or cobbles, but only 57.2% of the herbs and 59.8% of the graminoids grew on large stones. Plants are associated with large clasts because (1) coarse talus is more stable than fine sediment areas, which are more frequently disturbed by various geomorphic processes, and (2) large stones help conserve substrate water beneath them while moisture quickly evaporates from fine debris. Root patterns were studied for 30 plant species; 10 specimens for each species were excavated and inspected, and several root growth ratios calculated. All species exhibited pronounced root asymmetry, as roots for most plants grew upslope from their shoot base. For 23 species, all specimens had 100% of their roots growing upslope; for the other 7 species, 92.2-99.3% of below-ground biomass extended uphill. This uneven root distribution is ascribed to continual substrate instability and resulting talus shift; as cascading debris progressively buries roots and stems, plants are gradually pushed and/or stretched downhill. Various disturbance events affect root development. Slope erosion

    ) strongly influenced the community structure. In contrast, within the Gulf of Lion core, characterized by a homogeneous lithological structure of upper-slope environment, most detected groups were Bacteroidetes and, to a lesser extent, Betaproteobacteria. At both site, the detection of Betaproteobacteria coincided with increased terrestrial inputs, as confirmed by the geochemical measurements (Si, Sr, Ti and Ca). In the Gulf of Lion, geochemical parameters were also found to drive microbial community composition. Taken together, our data suggest that the palaeoenvironmental history of erosion and deposition recorded in the Western Mediterranean Sea sediments has left its imprint on the sedimentological context for microbial habitability, and then indirectly on structure and composition of the microbial communities during the late Quaternary.

  18. Earthquake and human impact on the sedimentology and geochemistry of Ahuriri Estuary, Hawke's Bay

    Three cores were collected from the intertidal and salt marsh sediments in Ahuriri Estuary, Hawke's Bay, and analysed by sedimentological, chemical and geochronological techniques. Signatures of various events, of both natural and anthropogenic origin, were identified. Evidence for the 1931 Hawke's Bay earthquake, which resulted in an uplift of one to two metres in the Napier area, is given by a change in grainsize distribution in a core from the southern shore of the Lower Estuary. The change to a high energy environment, similar to the present one in the Lower Estuary, has resulted in deposition of sand over fine silt. The data suggest increased sediment accumulation rates following the uplift event, which might be attributed to increased erosion in the upper catchment. There is no evidence of the earthquake at the two other sites sampled, which is probably due to their more sheltered location in the estuary. Post-European settlement impact is mainly restricted to the Lower Estuary, where increased concentrations of Zn, Cr, Pb and Cu may be due to industrial discharges. Evidence of agricultural runoff is given by an increase in Cu concentrations near the Poraiti Hills. The chemical data (Cl and S) suggest a change in the depositional environment in the Upper Estuary due to increased freshwater influx and/or decrease in seawater influence. Dating by 210 Pb infers that this occurred prior to 1931, but the origin and timing of the event are still to be determined. Sediment accumulation rates have averaged 2.5 mm/yr for the last 45 years in the Lower Estuary and 3.8 mm/yr for the last 70 years or so in the Upper Estuary. The variation probably reflects the difference in depositional environment, from a high energy environment dominated by tidal and wave action to a low energy environment with additional organic and fine sediment input from stream runoff. The various signatures identified are based on known events but may be used for identifying events in other less

    We use core descriptions and portable X-ray fluorescence analyses to identify lithofacies and stratigraphic surfaces for the Mesoproterozoic Nonesuch Formation within the Ashland syncline, Wisconsin. We group lithofacies into facies associations and construct a sequence stratigraphic framework based on lithofacies stacking and stratigraphic surfaces. The fluvial-alluvial facies association (upper Copper Harbor Conglomerate) is overlain across a transgressive surface by the fluctuating-profundal facies association (lower Nonesuch Formation). The fluctuating-profundal facies association comprises a retrogradational sequence set overlain across a maximum flooding surface by an aggradational-progradational sequence set comprising fluctuating-profundal, fluvial-lacustrine, and fluvial-alluvial facies associations (middle Nonesuch through lower Freda Formations). Lithogeochemistry supports sedimentologic and stratigraphic interpretations. Fe/S molar ratios reflect the oxidation state of the lithofacies; values are most depleted above the maximum flooding surface where lithofacies are chemically reduced and are greatest in the chemically oxidized lithofacies. Si/Al and Zr/Al molar ratios reflect the relative abundance of detrital heavy minerals vs. clay minerals; greater values correlate with larger grain size. Vertical facies association stacking records depositional environments that evolved from fluvial and alluvial, to balanced-fill lake, to overfilled lake, and returning to fluvial and alluvial. Elsewhere in the basin, where accommodation was greatest, some volume of fluvial-lacustrine facies is likely present below the transgressive stratigraphic surface. This succession of continental and lake-basin types indicates a predominant tectonic driver of basin evolution. Lithofacies distribution and geochemistry indicate deposition within an asymmetric half-graben bounded on the east by a west-dipping growth fault. While facies assemblages are lacustrine and continental

    The Karoo Supergroup in the Tuli Basin (South Africa) consists of a sedimentary sequence (˜450-500 m) composed of four stratigraphic units, namely the informal Basal, Middle and Upper Units, and the formal Clarens Formation. The units were deposited in continental settings from approximately Late Carboniferous to Middle Jurassic. This paper focuses on the ˜60-m-thick Basal Unit, which was examined in terms of sedimentary facies and palaeo-environments based on evidence provided by primary sedimentary structures, palaeo-flow measurements, palaeontological findings, borehole data (59 core descriptions) and stratigraphic relations. Three main facies associations have been identified: (i) gravelstone (breccias and conglomerate-breccias), (ii) sandstone and (iii) fine-grained sedimentary rocks. The coarser facies are interpreted as colluvial fan deposits, possibly associated with glaciogenic diamictites. The sandstone facies association is mainly attributed to channel fills of low sinuosity, braided fluvial systems. The coal-bearing finer-grained facies are interpreted as overbank and thaw-lake deposits, and represent the lower energy correlatives of the sandy channel fills. Sediment aggradation in this fluvio-lacustrine system took place under cold climatic conditions, with floating lake ice likely associated with lacustrine environments. Palaeo-current indicators suggest that the highly weathered, quartz-vein-rich metamorphic rock source of the Basal Unit was situated east-northeast of the study area. The accumulation of the Basal Unit took place within the back-bulge depozone of the Karoo foreland system. In addition to flexural subsidence, the amount of accommodation in this tectonic setting was also possibly modified by extensional tectonism in the later stages of the basin development. Based on sedimentological and biostratigraphic evidence, the coal-bearing fine-grained facies association displays strong similarities with the Vryheid Formation of the main Karoo

    Lake Ohrid, located on the Balkan Peninsula, is one of the very few lakes in the world that provides a continuous and high-resolution record of environmental change of >1.3 Ma. The sedimentary archive was drilled in spring 2013 within the scope of the International Continental Scientific Drilling Program (ICDP) and the Scientific Collaboration on Past Speciation Conditions in Lake Ohrid (SCOPSCO) project in order to investigate local and regional geological and paleoclimatic processes, as well as triggers of evolutionary patterns and endemic biodiversity. The continuous composite profile (584 m) of the main drill site DEEP was logged (XRF, MSCL) and subsampled for biogeochemical (TIC, TOC, TN, TS) and sedimentological (grain size) analyses. The lithology of the DEEP site indicates that the history of Lake Ohrid can roughly be separated into two parts, with the older section between 584 and 450 m depth being characterised by a sedimentary facies indicating shallow water conditions, which is likely younger than ca. 1.9 Ma. In the lowermost few meters of the succession gravels and pebbles hampered a deeper drilling penetration and indicate that fluvial conditions existed during the onset of lake formation. Together with geotectonic, seismic, and biological information, the data imply that the Ohrid basin formed by transtension during the Miocene, opened during the Pliocene and Pleistocene, and that the lake established between 1.9 and 1.3 Ma ago. The sediments of the younger part (DEEP site sequence and are subject of ongoing investigations aimed at identifying their specific volcanic sources and equivalent known tephra by using geochemical fingerprinting of glass fragments. This was already successfully approved for tephra horizons in the upper 247.8 m of the sequence, obtaining important chronological information from 11 well dated tephra layers. These tephrochronological constraints were complemented by ages obtained from tuning the consistent pattern of the

    Detailed outcrop analysis of the Lower Jurassic Kayenta Formation provides the basis for the formulation of a new sequence stratigraphic model for arid to semi-arid continental deposits and the generation of a comprehensive set of sedimentologic criteria for the recognition of ephemeral stream deposits. Criteria for the recognition of ephemeral deposits in the ancient record were divided into three categories according to the scale of the feature being considered. The first category takes into account sedimentary structures commonly found in the record of ephemeral stream deposits including hyperconcentrated and debris flow deposits, planar parallel bedding, sigmoidal cross-bedding, hummocky cross-bedding, climbing ripple lamination, scour-and-fill structures, convolute bedding, overturned cross-bedding, ball-and-pillow structures, pocket structures, pillars, mud curls, flaser lamination, algal lamination, termite nests, and vertebrate tracks. The second category is concerned with the mesoscale facies architecture of ephemeral stream deposits and includes waning flow successions, bedform climb, downstream accretion, terminal wadi splays, and channel-fill successions indicating catastrophic flooding. At the large-scale facies architecture level, the third category, ephemeral stream deposits are commonly arranged in depositional units characterized by a downstream decrease in grain size and scale of sedimentary structures resulting from deposition in terminal fan systems. Outcrops of the Kayenta Formation and its transition to the Navajo Sandstone along the Vermilion and Echo Cliffs of Northern Arizona indicate that wet/dry climatic cyclicity exerted a major control on regional facies architecture. Two scales of wet/dry climatic cyclicity can be recognized in northern Arizona. Three sequence sets composed of rocks accumulated under predominantly dry or wet conditions are the expression of long-term climatic cyclicity. Short-term climatic cyclicity, on the other hand

    Rare earth (REE) and trace element compositions of fossil vertebrate dental microremains have been studied in Silurian and Devonian vertebrate dental scales and spines in-situ, using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Samples were selected from the well-known Silurian bone beds of Vesiku and Ohesaare in Saaremaa island of Estonia, and a number of Lower Devonian localities from Spitsbergen (Svalbard), Andrée Land group. Biomineral preservation was assessed using spot semi-quantitative elemental chemistry (SEM-EDS) and electron back-scatter difractometry (EBSD) for cristallinity imaging. The obtained PAAS shale-normalised REE concentrations were evaluated using basic geochemical calculations and quantifications. The REE patterns from the Lower Devonian vertebrate apatite from Andrée Land, Spitsbergen (Wood Bay and Grey Hœk formations) did not show any recognisable taxon-specific behavior, but had rather well expressed differences of REE compositions related to biomineral structure and sedimentary settings, suggesting REE instead to reflect burial environments and sedimentological history. The Eu anomaly recorded in two of the studied localities but not in the other indicate different taphonomic conditions and palaeoenvironment, while La/Sm, La/Yb ratios sugeest considerable influence of terrestrial freshwater during the early diagenesis. The La/Yb and La/Sm plots also agree with the average REE concentrations, reflecting domination of the adsoption over substitution as principal REE uptake mechanism in the fossils which had significantly lower overall REE concentrations, and vice versa. Vesiku (Homerian, Wenlock) microremains yielded very uniform REE patterns with slightly lower overall REE concentrations in enameloid than in dentine, with strong enrichment in middle REE and depletion in heavy REE. Negative Europium (Eu) anomaly was pronounced in all the profiles, but Cerium (Ce) anomalies were not detected suggesting possible

    analyses (CCA showed that the availability of electron acceptors and the quality of electron donors (indicated by age strongly influenced the community structure. In contrast, within the Gulf of Lion core, characterized by a homogeneous lithological structure of upper-slope environment, most detected groups were Bacteroidetes and, to a lesser extent, Betaproteobacteria. At both site, the detection of Betaproteobacteria coincided with increased terrestrial inputs, as confirmed by the geochemical measurements (Si, Sr, Ti and Ca. In the Gulf of Lion, geochemical parameters were also found to drive microbial community composition. Taken together, our data suggest that the palaeoenvironmental history of erosion and deposition recorded in the Western Mediterranean Sea sediments has left its imprint on the sedimentological context for microbial habitability, and then indirectly on structure and composition of the microbial communities during the late Quaternary.

    Full Text Available The Fushan depression is a classic lacustrine rifted sub-basin in the Beibuwan Basin, South China Sea. The Paleogene Liushagang sequence is the main hydrocarbon-bearing stratigraphic unit in the depression. Using three-dimensional (3-D seismic data and logging data, we analyzed depositional setting of the Liushagang sequence. We use wave impedance inversion to describe progradational directions of provenance and the general distribution of sand body. The seismic facies was analyzed by using the seismic sedimentology approach based on 3-D seismic data, and summed into eight types of seismic facies which could be well related to sedimentary facies. Seismic attributes with six objective sequence boundaries were extracted. Consequently, four provenance system of Liushagang sequence in the study area were confirmed by the corresponding relationship between the geologic information and the warm color and higher value area of seismic attributes: (i the Hainan uplift provenance area in the south, (ii the Linggao uplift provenance area in the west, (iii the Yunlong uplift provenance area in the east and (iv the northern provenance area. The seismic sedimentology used in this study may provide new insights into a better understanding of depositional setting in continental lacustrine rifted basins.

    This paper discusses the research idea of description for stratigraphic-lithologic reservoir based on seismic sedimentology methods. The sandstone reservoir of Jurrassic XiShanyao Formation in Junggar Basin is studied according to the theory and approaches of seismic sedimentology. By making full use of borehole data, the technologies of layer correlation based on the stratigraphic sequence framework, the forward seismic modeling, the stratal slicing and lithologic inversion are applied. It describes the range of denudation line, the distribution characteristics of sedimentary facies of the strata, the vertical and horizontal distribution of sand bodies and the favourable oil-gas bearing prospective area. The results shows that study area are dominated braided delta deposition including underwater distributary channel and distributary bay microfacies, the nip-out lines of the formation are northeast to southwest from north to south, the second Middle Jurassic sand body is the most widely distributed one among three sand bodies, the prospective oil-gas bearing area located in the south part and around the YG2 well area. The study result is effective on the practice of exploration in study area.

    2017-08-01

    This special issue of Geo-Marine Letters presents selected contributions from the 9th International Conference on Tidal Sedimentology held on 17-19 November 2015 in Puerto Madryn, Chubut Province, Patagonia, Argentina. The guest editors are the conference organizers Roberto A. Scasso and José I. Cuitiño. Gerardo M. Perillo was the head of the Scientific Committee. The conferences on tidal sedimentology have been traditionally held every 4 years. However, only 3 years separated the last conference held in Caen (France, 2012) from this conference. Increasing numbers of contributions and the growing interest in tidal sedimentation have been the reasons for shortening the inter-conference period. The 2015 conference served as a discussion forum focusing on advances in modern and ancient tidal sedimentation at different locations worldwide. The papers presented in this Special Issue provide a selective view of the latest research results, the main topics dealing with tidal hydrodynamics and sediment transport, tidal coastal morphodynamics, modern and ancient tidal sedimentation, geotechnical processes in tidal environments, and tidal basins, facies and reservoirs.

    Recent sedimentary and morphological changes at the new mouth of Medjerda-River (Gulf of Tunis) are investigated using a multiproxy approach of sediment cores complited by 210Pbex and 137Cs method dating. The subject of the study is to focus on surveying the sedimentary evolution of Medjerda-Raoued Delta caused by the human intervention in the management of the main tributaries of the Medjerda-River (artificial channel of Henchir Tobias). Sediment cores (CEM-1 and CEM-3) were subjected to both multiproxy approaches (Grain size, geochemical analysis and dating radiometric 210Pbex and 137Cs). The sedimentological analysis of the new deltaic deposits shows a progradation sequence with the silt and clay deposits on the historic sandy substratum. The mean grain size evolution on the old beach profile shows a decreasing trend from backshore (CEM-3) to nearshore (CEM-1). The geochemical results show varying concentrations of chemical elements such as Fe, K, Rb, Nb, Cr, Ti, Ba, Ca, Sr, Zr, V, and potentially toxic metal trace elements such as Pb, Zn and the As. The Principal component Analysis (PCA) applied in the geochemical elements evolution confirms the marine origin of the sand deposits in the basic layers of the two cores. The chronological method (210Pbex and 137Cs) affirms that the first fluvial deposits were set up only after 1950. The sedimentological and geochemical result confirm the actual unless of coarser fluvial supplies under the human activities leading the negative coastal sediment balance and the shoreline retreat as well.

Acta Geologica Polonica, 63 (2), 175-199. Warszawa. The continental, coal bearing Steierdorf Formation, Hettangian - Sinemurian in age, is included in the Mesozoic cover of the Reşiţa Basin, Getic Nappe, South Carpathians, Romania. The Steierdorf Formation can be studied in Anina, a coal mining center and an exceptional locality for Early Jurassic flora and fauna, occurring in the middle of the Reşiţa Basin. This paper presents the results of sedimentological, stratigraphical and paleobotanical researches undertaken in Colonia Cehă open cast mine in Anina, where the Steierdorf Formation outcrops widely. Several sedimentary facies associations have been described, these associations permitting the reconstruction of various depositional systems such as alluvial fans, braided and meandering river systems, as well as lacustrine and coal generating marsh systems of the Steierdorf Formation. The sedimentary associations recorded within the Steierdorf Formation show a gradual fining upward trend, pointing to a rising marine water table and a decreasing relief within the source area.

    The problem of massive emissions of carbon dioxide (CO 2 ) from the burning of fossil fuels and their climatic impact have become major scientific and political issues. Future stabilization of the atmospheric CO 2 content requires a drastic decrease of CO 2 emissions worldwide. In this study, energy utilization and its major environmental impacts are discussed from the standpoint of sustainable development, including anticipated patterns of future energy use and subsequent environmental issues in Turkey. Several aspects relating to energy utilization, renewable energy, energy efficiency, environment and sustainable development are examined from both current and future perspectives. Turkey is an energy importing country; with more than half of the energy requirement being supplied by imports. Domestic oil and lignite reserves are limited, and the lignites are characterised by high ash, sulfur and moisture contents. Because of increasing energy consumption, air pollution is becoming a great environmental concern for the future in the country. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions for sustainable energy development and environmental pollution prevention in Turkey. Turkey's geographical location has several advantages for extensive use of most of the renewable energy sources

    The depletion of tylosin residues in edible turkey tissues was followed after 3 days of administration of tylosin tartrate at 500 mg l-1 in drinking water, to 30 turkeys. Immediately after the end of the treatment (day 0) and at day 1, 3, 5 and 10 of withdrawal, six turkeys (three males and three females) per time were sacrificed and samples of edible tissues were collected. Tissue homogenates were extracted, purified and analysed by HPLC according to a method previously published for the analysis of tylosin residues in pig tissues. In all tissues, tylosin residues were already below the detection limits of 50 micrograms kg-1 at time zero. However, in several samples of tissues (skin + fat, liver, kidney, muscle), from the six turkeys sacrificed at that time, one peak corresponding to an unknown tylosin equivalent was detected at measurable concentrations. The identification of this unknown compound was performed by LC-MS/MS analysis of the extracts from incurred samples. The mass fragmentation of the compound was consistent with the structure of tylosin D (the alcoholic derivative of tylosin A), the major metabolite of tylosin previously recovered and identified in tissues and/or excreta from treated chickens, cattle and pigs.

  17. Review of Turkey's renewable energy potential

    Ozgur, M. Arif

    2008-01-01

    The use of renewable energy has a long history. Biomass, for instance, has been used for heating and cooking, while wind has been used in the irrigation of fields and to drive windmills for centuries. Although Turkey has many energy resources, all of these with the exception of coal and hydropower, cannot meet the total energy demand. Turkey has been importing resources to meet this deficit. These resources have become increasingly expensive and also have undesirably high emissions ratings. Turkey has an extensive shoreline and mountains and is rich in renewable energy potential. The share of renewables on total electricity generation is 29.63% while that of natural gas is 45% for the year 2006. The projection prepared for the period between 2006 and 2020 aims an annual growth of 8% for the total electricity generation. According to this projection, it is expected that renewables will have a share about 23.68% with a decrease of 5.95% while natural gas will have a share about 33.38% for 2020. This paper presents the present state of world renewable energy sources and then looks in detail at the potential resources available in Turkey. Energy politics are also considered. (author)

    2010-01-01

    In this report, the activity concentrations of natural and artificial radionuclides and gross alpha/beta activities measured in the environmental and food samples provided from Turkey's seven geographical regions within the environmental radioactivity monitoring program in 2009 and absorbed gamma dose rates in outdoor obtained by means of car-borne measurement system (Mobysis) are presented. The activity concentrations of the natural and artificial radionuclides and gross alpha/beta activities in the samples were measured by using the gamma spectrometry, the alpha spectrometry, the liquid scintillation counter and the gross alpha /beta counting system. The mean activity concentrations of 2 26Ra, 2 32Th and 4 0K in the analyzed surface samples were found as 34,7 ± 1,7 Bq kg - 1, 35,4 ± 0,8 Bq kg - 1 and 450,0 ± 17,9 Bq kg - 1, respectively, while the mean activity concentration of the fission product 1 37Cs was found as 11,6 ± 0,5 Bq kg - 1. The mean absorbed gamma dose rate in outdoor due to external exposure emitted by natural radionuclides in soil samples and the corresponding annual effective dose were evaluated as 54,6 nGy h - 1 and 0,07 mSv y - 1, respectively. The activity concentrations of 2 38U, 2 32Th and 2 26Ra in the analyzed food samples were lower than the minimum detectable activity (MDA) while 1 34Cs radionuclide was not observed. The mean activity concentrations of 1 37Cs and 9 0Sr radionuclides measured in the milk samples are 0,28 Bq L - 1 and 0.05 Bq L - 1, respectively. These values are lower than the limit value specified for foods subjected to control based on the regulation of the EU 737/90/EC. The total annual effective dose arising from the internal exposure from radiation emitting from 4 0K, l 37Cs and 9 0Sr radionuclides analyzed in the food samples are evaluated as 193,0 μSv. In conclusion, the results of the monitoring programme in 2009 show that the levels of radioactivity in the environment are low and do not pose any significant

  9. Flow dynamics at the origin of thin clayey sand lacustrine turbidites: Examples from Lake Hazar, Turkey

    Hage, Sophie

    2017-04-18

    Turbidity currents and their deposits can be investigated using several methods, i.e. direct monitoring, physical and numerical modelling, sediment cores and outcrops. The present study focuses on thin clayey sand turbidites found in Lake Hazar (Turkey) occurring in eleven clusters of closely spaced thin beds. Depositional processes and sources for three of those eleven clusters are studied at three coring sites. Bathymetrical data and seismic reflection profiles are used to understand the specific geomorphology of each site. X-ray, thin sections and CT-scans imagery combined with grain-size, geochemical and mineralogical measurements on the cores allow characterisation of the turbidites. Turbidites included in each cluster were produced by remobilization of surficial slope sediment, a process identified in very few studies worldwide. Three types of turbidites are distinguished and compared with deposits obtained in flume studies published in the literature. Type 1 is made of an ungraded clayey silt layer issued from a cohesive flow. Type 2 is composed of a partially graded clayey sand layer overlain by a mud cap, attributed to a transitional flow. Type 3 corresponds to a graded clayey sand layer overlain by a mud cap issued from a turbulence-dominated flow. While the published experimental studies show that turbulence is damped by cohesion for low clay content, type 3 deposits of this study show evidence for a turbulence dominated mechanism despite their high clay content. This divergence may in part relate to input variables such as water chemistry and clay mineralogy that are not routinely considered in experimental studies. Furthermore, the large sedimentological variety observed in the turbidites from one coring site to another is related to the evolution of a sediment flow within a field scale basin made of a complex physiography that cannot be tackled by flume experiments.

  10. Mediterranean energy perspectives - Turkey. Executive summary

    International Nuclear Information System (INIS)

    2014-09-01

    This in-depth study provides insight into Turkey's energy profile from the early 1960's to the present and an outlook to 2030. MEP-Turkey presents detailed analysis and data on the supply and demand balance for the major components of the energy sector with particular emphasis on sectoral analysis. It is based on OME's proprietary Mediterranean Energy Econometric Model for Turkey developed for this publication. The outlook to 2030 presents two possible pathways for energy demand based on different assumptions. The conservative scenario considers past trends, policies in force and on-going projects, but takes a cautious approach regarding the implementation and timing of policy measures and planned projects. The proactive scenario assumes effective achievements to lessen dependence on imported fuels by giving emphasis to production of domestic resources, stronger efficiency programmes and a more diversified energy supply mix including more renewable energy. To achieve ambitious energy efficiency levels and implement as much renewable energy sources as foreseen in the Proactive Scenario will require unwavering political will, strong policies and measures, as well as sizeable investments, especially by the private sector. Both scenarios, built from the same assumption for population, economic growth, and international fossil-fuel prices, are based on the premise that energy demand will be met. Turkey's future, stimulated by a booming economy and population, an export-oriented industry and a blossoming domestic market, looks bright. The energy needed to fuel this growth will depend greatly on the paths chosen. In this context, the country finds itself at a historical crossroads in its development, as the energy policy choices it makes today will shape Turkey's energy future and its ability to attract the considerable investments required in the energy industry

  11. Homosexuality and police terror in Turkey.

    1993-01-01

    Being a way of sexual living as old as human history, homosexuality occupies an interesting place in the life of the Turkish people of the Republic of Turkey. This has been so since the days of the glorious Ottoman Empire. In the year 1987, instead of investigating the roots of homosexuality, the pressing need has become to present a particular view of homosexuality in Turkey today. To be more specific, there is a need to explain the problems of Turkish homosexuals and suggest certain vital solutions. Our country is constantly endeavoring to become "westernized" and it is claimed that steps are being taken toward that modernization. Despite this fact, homosexuals are confronted with such great problems that it is not difficult to justify those who say that there is no democracy in Turkey. I will try to explain these problems with documentary evidence and without exaggeration. In doing so, I shall make use of new material in my book, published under the title of Homosexuality in Turkey: Yesterday, Today. Beginning in March of 1986, we compiled a list of the attitudes of the police toward gays, involving pressure and cruelty that can be qualified as torture. Despite this situation, instead of being more democratic and humane, in April 1987 the police force employed terror tactics against homosexuals in Istanbul. This was "the straw that broke the camel's back." Soon after this act of oppression, 18 gays, acting on our suggestions, sued the police for the first time. They then submitted a petition to the Attorney-General and later launched a hunger strike in Taksim Square. These represent movements of importance in the political history of Turkey. From now on homosexuals, too, will have the right to speak out in political affairs.

  12. Prevention of hemoglobinopathies in Turkey

    Full Text Available Hemoglobinopathies are the most common genetic disorders in Turkey. The incidence of beta thalassemia and sickle cell trait (HbAS is 2.0% and 0.3% respectively. In addition to HbS, 51 abnormal hemoglobins and 42 different beta thalassemia mutations have been detected by DNA analysis. In Turkey, beta thalassemia and sickle cell anemia cause major health problems. For thirty years, screening programs for carriers, genetic counseling and prenatal diagnosis have sought to prevent hemoglobinopathies. In 1983, the first prenatal diagnosis center was established for sickle cell anemia and beta thalassemia at Hacettepe University, Ankara. After many populationscreening studies, a law was passed in 1993 by the Turkish Parliament for the eradication of hemoglobinopathies. Forty-one premarital screening centers were set up by the Ministry of Health in the 33 provinces where most of the transfusion-dependent thalassemic patients live. The mothers at risk for hemoglobinopathies were given genetic counseling and directed to prenatal diagnosis centers. Since 1990, four prenatal diagnosis centers have been established at university hospitals in Adana, Antalya, Istanbul and Izmir. A total of 5255 prenatal diagnoses have been made for sickle cell anemia and beta thalassemia in 5 centers; 1338 fetuses have been diagnosed as homozygous or compound heterozygotes for hemoglobinopathies. Prenatal diagnosis was performed on families who had decided to terminate the pregnancy if it were to be found that the fetus was affected. 血红蛋白病是土耳其最为常见的遗传性疾病。乙型地中海贫血和镰状细胞性状(HbAS)的发病率分别为2.0%和0.3%。除HbS外,已通过NDA分析检测出51种异常血红蛋白和42种乙型地中海贫血突变基因。在土耳其,乙型地中海贫血和镰状细胞性贫血会导致严重的健康问题。30年来,一直在为病原携带者提供筛选项目,以及遗传咨询和产前诊断服务,

  13. Sedimentological Properties of Natural Gas Hydrates-Bearing Sands in the Nankai Trough and Mallik Areas

    Uchida, T.; Tsuji, T.; Waseda, A.

    2009-12-01

    The Nankai Trough parallels the Japanese Island, where extensive BSRs have been interpreted from seismic reflection records. High resolution seismic surveys have definitely indicated gas hydrate distributions, and drilling the MITI Nankai Trough wells in 2000 and the METI Tokai-oki to Kumano-nada wells in 2004 have revealed subsurface gas hydrate in the eastern part of Nankai Trough. In 1998 and 2002 Mallik wells were drilled at Mackenzie Delta in the Canadian Arctic that also clarified the characteristics of gas hydrate-dominant sandy layers at depths from 890 to 1110 m beneath the permafrost zone. During the field operations, the LWD and wire-line well log data were continuously obtained and plenty of gas hydrate-bearing sand cores were recovered. Subsequence sedimentological and geochemical analyses performed on those core samples revealed the crucial geologic controls on the formation and preservation of natural gas hydrate in sediments. Pore-space gas hydrates reside in sandy sediments mostly filling intergranular porosity. Pore waters chloride anomalies, core temperature depression and core observations on visible gas hydrates confirm the presence of pore-space gas hydrates within moderate to thick sandy layers, typically 10 cm to a meter thick. Sediment porosities and pore-size distributions were obtained by mercury porosimetry, which indicate that porosities of gas hydrate-bearing sandy strata are approximately 45 %. According to grain size distribution curves, gas hydrate is dominant in fine- to very fine-grained sandy strata. Gas hydrate saturations are typically up to 80 % in pore volume throughout most of the hydrate-dominant sandy layers, which are estimated by well log analyses as well as pore water chloride anomalies. It is necessary for investigating subsurface fluid flow behaviors to evaluate both porosity and permeability of gas hydrate-bearing sandy sediments, and the measurements of water permeability for them indicated that highly saturated

  14. Sedimentology and arsenic pollution in the Bengal Basin: insight into arsenic occurrence and subsurface geology.

    Hills, Andrew; McArthur, John

    2014-05-01

    The Bengal delta system is a geologically recent feature overlying a deeply incised palaeo-surface formed during the Last Glacial Maximum. This surface is a series of terraces and valleys created by river incision (Goodbred & Kuehl 2003). The terraces were weathered, forming a thin, indurated laterite deposit (Goodbred & Kuehl 2000) at depths greater than 50 m. McArthur et al. (2008) define this as a palaeosol and have identified it at depths greater than 30 m though out Bangladesh and West Bengal. It has been observed that arsenic concentrations at these sites are lower than the rest of the delta. It has been assumed that the surface morphology at sites where there is a palaeosol are similar and can therefore be characterised by remote sensing, in the form of Google Earth images. Sites were selected in Bangladesh and West Bengal, from work by McArthur et al. (2011); Hoque et al. (2012), where groundwater chemistry and sedimentology data are available making it possible to determine if the subsurface is a palaeo-channel or palaeo-interfluve. Arsenic concentration data have been inputted into Google Earth and the palaeo-channels marked where the arsenic concentration is greater than 10 µg/L, and palaeo-interfluves where arsenic concentration is less than 10 µg/L. The surface morphologies in these domains have been examined for similarities, and it was shown that avulsion scars and abandoned river channels are found where arsenic concentrations are greater than 10 µg/L. Conversely the surrounding areas that are devoid of channel scars have arsenic concentrations less than 10 µg/L. Using the correlation between avulsion features being representative of palaeo-channels and high arsenic concentrations, sites were selected that had a similar surface morphology to the type localities. A comparison of these images and arsenic concentrations showed that the postulate is valid for over 80 percent of cases. Where this is not valid, this could indicate that the subsurface

  15. The Geopolitics of Water and Oil in Turkey

    2009-01-01

    Throughout history, few nations have been as successful in leveraging their geographic location as Turkey. As the center of two of the most powerful civilizations of all time, the Byzantine and Ottoman Empires, Turkey was the bridge between East and West, a bustling center of trade and a strategic economic and political nexus between regions of the world. In addition to its geographic power, Turkey has historically possessed substantial water resources. Unlike many water parched areas of the Middle East, Turkey's water capacity has allowed it to grow large populations and build elaborate cities. In the modern era, Turkey once again has an opportunity to regain its historical role, as the state where today's geopolitics of energy coincides with Turkey's traditional geopolitics of water. Turkey's central location, this time not between East and West, but between producers and consumers of energy, gives it a central, geopolitical role in world affairs, both in oil and gas. Moreover, Turkey's water resources can be utilized to reinforce Turkey's strategic energy role in the region, by building a strategy of cooperation with water-poor countries from the Levant to the Arabian Peninsula. Throughout history, water and energy have been among the most fundamental resources of civilization, at the very base of Maslow's hierarchy of needs essential to fostering human growth and development for thousands of years. It is seldom appreciated how linked water and energy truly are. Producing, transferring, and supplying energy requires a significant amount of water, just as the extraction, purification, and even desalination of water requires a significant amount of energy. As both energy and water grow scarcer throughout the future, nations such as Turkey can gain considerable influence as a result of their geographic locations and natural endowments.

    2005-10-01

    A paleoenvironmental reconstruction of the southeast coast of Buenos Aires province, Argentina, is made mainly on the basis of paleontological and paleoichnological studies, supported by sedimentological analyses and radiocarbon dating. Continental late Pleistocene and continental, transitional, and marine Holocene stratigraphic units are identified. The former comprises fossil mammals and ichnites of 16000-12,000 BP. The continental early Holocene time, ca. 8100 BP, is represented by an interdune paleoenvironment in which shallow brackish ponds were colonized by diatoms, fish, rodents, and birds. A transitional paleoenvironment in the middle Holocene—6930-6570 BP—is recorded by deposits formed by estuarine crabs. During the late Holocene, between 5000 and 4800 BP, a marine transgression was recorded by a rich mollusc fauna.

    2018-01-01

    The Colorado River in the southwestern U.S. provides an excellent natural laboratory for studying the origins of a continent-scale river system, because deposits that formed prior to and during river initiation are well exposed in the lower river valley and nearby basinal sink. This paper presents a synthesis of regional stratigraphy, sedimentology, and micropaleontology from the southern Bouse Formation and similar-age deposits in the western Salton Trough, which we use to interpret processes that controlled the birth and early evolution of the Colorado River. The southern Bouse Formation is divided into three laterally persistent members: basal carbonate, siliciclastic, and upper bioclastic members. Basal carbonate accumulated in a tide-dominated marine embayment during a rise of relative sea level between 6.3 and 5.4 Ma, prior to arrival of the Colorado River. The transition to green claystone records initial rapid influx of river water and its distal clay wash load into the subtidal marine embayment at 5.4-5.3 Ma. This was followed by rapid southward progradation of the Colorado River delta, establishment of the earliest through-flowing river, and deposition of river-derived turbidites in the western Salton Trough (Wind Caves paleocanyon) between 5.3 and 5.1 Ma. Early delta progradation was followed by regional shut-down of river sand output between 5.1 and 4.8 Ma that resulted in deposition of marine clay in the Salton Trough, retreat of the delta, and re-flooding of the lower river valley by shallow marine water that deposited the Bouse upper bioclastic member. Resumption of sediment discharge at 4.8 Ma drove massive progradation of fluvial-deltaic deposits back down the river valley into the northern Gulf and Salton Trough. These results provide evidence for a discontinuous, start-stop-start history of sand output during initiation of the Colorado River that is not predicted by existing models for this system.

    This research is conducted to understand the sedimentology and morphological change before and during the northeast monsoon at the east coast of peninsular Malaysia. The increase in wind speed, wave energy and rainfall during the northeast monsoon are believed to causes the coastal erosion to increase during the season. Rapid development along the east coast area might disrupt the sediments distribution which can increase the coastal erosion rate every year. The understanding on the sediments distribution, erosion and deposition as well as the morphological change can help to figure out if the coastal erosion can affect the infrastructure in the future. The result of the study can show the necessity to perform mitigation or any required action toward the problem that might happen

    Based on detailed logs presented here at 1:10, the cored Upper Maastrichtian succession of the M-10X (Dan Field) and E-5X (Tyra SE Field) wells in the southern Danish Central Graben is subdivided into eight lithofacies and five ichnofabrics. The dominant bioturbated or laminated chalk mudstones and subordinate sparse skeletal wackestones are largely the result of pelagic carbonate production, sedimented by suspension settling and small volume, low density turbidity currents. Evidence of winnowing/reduced sedimentation rates is yielded by rare incipient hardgrounds; a well-developed mature hardground profile is developed at the Cretaceous-Danian boundary (the ''Maastrichtian hardground''). Rare marl laminae are recorded and a discrete marly chalk bed associated with an interval of finegrained skeletal chalk wackestones near the top of the Maastrichtian is recognised in both wells. Comparison between the two wells demonstrates that the m-scale laminated-bioturbated chalk cycles described from the Dan Field area are both stratigraphically and areally restricted; this has implications for both cyclostratigraphic correlation and reconstruction of depositional environments and Late Maastrichtian evolution of the Danish Central Graben.

    An influenza virus was isolated from turkeys with an acute disease causing 30% mortality. The virus was subtyped as H5 N8. The nomenclature A/turkey/Ireland/83 (H5 N8) is proposed for this isolate. The virus had an ICPI of 1.80 to 1.85 for 1-day-old chicks and an IVPI of 2.74 for 6-week-old chickens. Following oronasal inoculation of juvenile and adult turkeys, chickens and ducks with the isolate, 100% mortality occurred in turkeys and chickens. No clinical signs were observed in inoculated ducks, but all developed serum antibody titres against the virus.

    Full text : The global demand for electricity is rapidly increasing. There is growing uncertainty in regard to the supply and prices of oil and natural gas. These considerations have opened new prospects for the development of nuclear energy on a global state. Despite the negative impact of the Fukushima Daichi accident, still some countries are considering or have expressed interest in developing nuclear power programmes. As the country using nuclear technology is primarily responsible for safety and as operational safety cannot be out sourced, building of sound safety expertise and strong safety culture is an essential precondition for the country introducing nuclear technology. Turkey's energy policy is naturally focused on the security, sustainability and competitiveness of energy supply. It is designed to sustain targeted economic and social growth in the long run. Turkey remains resolutely committed to the goal of ensuring safe, secure and peaceful utilization of nuclear energy

    Full Text Available Polydactyly is among the most frequently encountered congenital anomalies of the extremities. Although it is usually presented in an isolated and sporadic manner, familial cases can also be rarely encountered. Such familial polydactyly cases usually follow an autosomal dominant inheritance with variable genetic penetration and are usually bilateral and symmetric. A case of rare familial polydactyly from Turkey is presented. Four siblings, two girls and two boys, presented with bilateral, symmetric preaxial polydactyly affecting both hands and feet. These siblings also had four other unaffected siblings along with an affected father and grandmother (the father’s mother. Although the cases portrayed duplication at different levels, the general definition of familial polydactyly with bilateral, symmetric inheritance is observed in these cases. Other rare familial polydactyly cases have been reported in the literature as well, and this case serves as a typical example of this rare entity from Turkey.

  11. Contamination of fodder and radioactivity in turkeys

    1985-01-01

    Radioactivity was determined in mixed fodder (IB, IC, IE) and in turkeys which were given that feeding stuff. In animals (25 males and 25 females) fed with the above mixed fodder for 16-24 weeks radioactivity was assessed in internal organs and in their tissues. It was found that radioactivity ranged from 322.2 Bq/kg to 190.6 Bq/kg. In males the highest contamination was found in the spleen (average 0.108 Bq/g), in skeletal muscles (0.082 Bq/g), and in the liver (0.080 Bq/g), and the lowest in the skin (0.046 Bq per 1 g). The findings indicate that radioactivity of carcasses and internal organs in turkeys fed with contamined fodder was much lower than that in fodder. 6 refs., 1 tab. (author)

    1999-01-01

    Large-scale electricity generation provides versatile energy of the highest quality. Today, fossil fuels such as coal, oil, and natural gas are the primary sources of this energy. However, these fossil energy sources are limited and using fossil energy sources has the undesirable effect of releasing emissions that burden the environment and alter the climate. Therefore, governments and companies all over the world should find new and renewable energy sources. On the other hand, over the past two decades, power station construction programs in the developing countries accounted for nearly 30% of total public investment. In a large number of these countries, shortages of electricity have become a critical constraint to economic growth. In Turkey, from 1980 to 1995, the amount for electricity generated increased about fourfold from 23,275 Gwh to 86,247 Gwh, and annual growth rates were in the double digits. This is a good development, but not enough for Turkey. (author)

    2017-12-01

    Full Text Available The necessity of emphasizing the importance of industrial production for the sustainable growth and development of Turkey has been a topic of discussion in political and academia circles. The growth in industrial production (output depends on the investment in manufacturing sectors and the demand for the products. Along with internal demand, Turkey tries to support its manufacturing base with export (incentives. Manufacturing items occupy the greatest share of products in export sales. The development of manufacturing capabilities of the country is clearly based on the demand from inside and out. The effect of Turkey’s export on its industrial production throughout 2000’s has been analyzed. For this purpose we developed a VAR model where industrial production index was the dependent variable and export, investment, and interest rate were independent variables. All independent variables were found to be significantly explaining industrial production.

    The objective of this paper is to describe some of the major healthcare information technology (IT) infrastructures in Turkey, namely, Sağlık-Net (Turkish for "Health-Net"), the Centralized Hospital Appointment System, the Basic Health Statistics Module, the Core Resources Management System, and the e-prescription system of the Social Security Institution. International collaboration projects that are integrated with Sağlık-Net are also briefly summarized. The authors provide a survey of the some of the major healthcare IT infrastructures in Turkey. Sağlık-Net has two main components: the National Health Information System (NHIS) and the Family Medicine Information System (FMIS). The NHIS is a nation-wide infrastructure for sharing patients' Electronic Health Records (EHRs). So far, EHRs of 78.9 million people have been created in the NHIS. Similarly, family medicine is operational in the whole country via FMIS. Centralized Hospital Appointment System enables the citizens to easily make appointments in healthcare providers. Basic Health Statistics Module is used for collecting information about the health status, risks and indicators across the country. Core Resources Management System speeds up the flow of information between the headquarters and Provincial Health Directorates. The e-prescription system is linked with Sağlık-Net and seamlessly integrated with the healthcare provider information systems. Finally, Turkey is involved in several international projects for experience sharing and disseminating national developments. With the introduction of the "Health Transformation Program" in 2003, a number of successful healthcare IT infrastructures have been developed in Turkey. Currently, work is going on to enhance and further improve their functionality.

    Avian pneumovirus (APV) is the cause of a respiratory disease of turkeys characterized by coughing, ocular and nasal discharge, and swelling of the infraorbital sinuses. Sixty turkey poults were reared in isolation conditions. At 3 weeks of age, serum samples were collected and determined to be free of antibodies against APV, avian influenza, hemorrhagic enteritis, Newcastle disease, Mycoplasma gallisepticum, Mycoplasma synoviae, Mycoplasma meleagridis, Ornithobacterium rhinotracheale, and Bordetella avium. When the poults were 4 weeks old, they were inoculated with cell culture-propagated APV (APV/Minnesota/turkey/2a/97) via the conjunctival spaces and nostrils. After inoculation, four poults were euthanatized every 2 days for 14 days, and blood, swabs, and tissues were collected. Clinical signs consisting of nasal discharge, swelling of the infraorbital sinuses, and frothy ocular discharge were evident by 2 days postinoculation (PI) and persisted until day 12 PI. Mild inflammation of the mucosa of the nasal turbinates and infraorbital sinuses was present between days 2 and 10 PI. Mild inflammatory changes were seen in tracheas of poults euthanatized between days 4 and 10 PI. Antibody to APV was detected by day 7 PI. The virus was detected in tissue preparations and swabs of nasal turbinates and infraorbital sinuses by reverse transcription polymerase chain reaction, virus isolation, and immunohistochemical staining methods between days 2 and 10 PI. Virus was detected in tracheal tissue and swabs between days 2 and 6 PI using the same methods. In this experiment, turkey poults inoculated with tissue culture-propagated APV developed clinical signs similar to those seen in field cases associated with infection with this virus.

    Fumonisins are mycotoxins that are found worldwide. They are mainly produced by Fusarium verticillioides during its development on corn. The main toxic effects of these molecules have been well characterized in poultry in the case of acute exposure, but the subclinical and economic effects of chronic exposure are less known. Whereas the latest European recommendations suggest that maximal levels of fumonisins in corn could reach 60 mg/kg and the maximal contamination of poultry feeds could reach 20 mg/kg, no study is available at this level in turkeys. The aim of the present work was thus to characterize the effects of exposure to fumonisins (concentrations of 0, 5, 10, and 20 mg of fumonisin B1 + fumonisin B2/kg of feed) on feed consumption and growth in turkeys over a period of 9 wk. Main biochemical parameters of the liver and alteration of sphingolipid metabolism were investigated in plasma, liver, and kidney. The main results showed no effect on feed consumption and growth in exposed turkeys. Moreover, no effect was observed on the weight of tissues and markers of liver injury. By contrast, a disruption of sphingolipid metabolism was clear at a level of exposure of 10 and 20 mg of fumonisin B1 + fumonisin B2 mg/kg of feed. Both hepatic and kidney concentrations of sphinganine increased gradually throughout the exposure period. These results reveal that disruption of sphingolipid metabolism is an early and sensitive biomarker of fumonisins exposure in turkeys; the consequences on these alterations remain to be established.

  4. Issues of Teaching Tuvan Language in Turkey

    Directory of Open Access Journals (Sweden)

    Margarita B. Kungaa

    2018-03-01

    Full Text Available Tuvan language is taught and studied both in the Republic of Tuva and beyond its borders. Alongside with other Turkic languages, it is taught at a number of universities in Turkey – and like all languages belonging to the same group, it is taught to Turkish students not as a foreign, but as a cognate tongue. Speaking from her own experience as lecturer in Tuvan language and literature at the University of Ankara (1997-2003, the author shares her opinions on the issues language instructors frequently face when teaching Tuvan to Turkish students. Since all Turkic languages are understood to stem back to a single ancestor – Proto-Turkic language, the absolute majority of Turkologists see them as dialects of this ancestor tongue. Correspondingly, in their learning experience Turkish students distinguish between foreign languages and those cognate to their mother tongue. Overall, about 20 Turkish universities offer courses in various Turkic languages. At the moment, quite a lot of specialists in Tuvan – both researchers and educators – work in Turkey. However, there is a marked lack of student motivation to study Tuvan. Students see little incentives of professional career growth except becoming an academic linguist. Another notable issue is the absence of textbooks, study manuals, or Tuvan-Turkish and Turkish-Tuvan phrasebooks which could facilitate achieving the required level of command of Tuvan by Turkish students. This problem as yet remains unsolved. For Turkish students, learning Tuvan opens the prospect of becoming a Turkologist. For the Republic of Tuva, the presence of such specialists would help popularize Tuvan culture and enhance collaboration between Tuva and Turkey in the areas of science, culture and economy. This will also help develop the relations between Turkey and Russian Federation.

    1998-01-01

    Channelization on Turkey Creek and its receiving stream, the South Fork Big Nemaha River, has disturbed the equilibrium of Turkey Creek and has led to channel-stability problems, such as degradation and channel widening, which pose a threat to bridges and land adjacent to the stream. As part of a multiagency study, the U.S. Geological Survey assessed channel stability at two bridge sites on upper and middle portions of Turkey Creek by analyzing streambed-elevation data for gradation changes, comparing recent cross-section surveys and historic accounts, identifying bank-failure blocks, and analyzing tree-ring samples. These results were compared to gradation data and trend results for a U.S. Geological Survey streamflow-gaging station near the mouth of Turkey Creek from a previous study. Examination of data on streambed elevations reveals that degradation has occurred. The streambed elevation declined 0.5 m at the upper site from 1967-97. The streambed elevation declined by 3.2 m at the middle site from 1948-97 and exposed 2 m of the pilings of the Nebraska Highway 8 bridge. Channel widening could not be verified at the two sites from 1967-97, but a historic account indicates widening at the middle site to be two to three times that of the 1949 channel width. Small bank failures were evident at the upper site and a 4-m-wide bank failure occurred at the middle site in 1987 according to tree ring analyses. Examination of streambed-elevation data from a previous study at the lower site reveals a statistically significant aggrading trend from 1958-93. Further examination of these data suggests minor degradation occurred until 1975, followed by aggradation.

The research group consisted of 6061 adolescents. With an age average of 15.53 years. The Inventory of Attachment to Parents and Friends- Brief Form (EABE was used as data acquisition tool. The results of the study indicated significant difference between the scores of students regarding the inventory of attachment to parents according to regions. Evaluating the findings regarding attachment to father and mother together, the findings were similar, and the attachment levels of adolescents in Middle Anatolia, Eastern Anatolia and Black Sea Region were found to be higher than the ones in other regions. This result may be related with socioeconomic, geographical and cultural structures of the regions. Examining the finding according to gender variable, the scores of male students are significantly lower than the scores of female students. As a result according to the data gained from a wide sample group; the main factors for the attachment of adolescents to their parents in Turkey are the geographical regions in Turkey and the gender.

    2012-01-01

    In Turkey, which ranks the tenth country worldwide in the sunflower (Helianthus annuus L.) production, 55% of the production is carried out in Thrace Region. Therefore, agricultural enterprises in Thrace Region, situated in the European part of Turkey have specialized in producing sunflower, and have become the centre of vegetable oil industry in the region in terms of produced raw material. This research was conducted in 182 agricultural enterprises in 3 provinces of Thrace Region in Turkey and its objective was to determine input/output relations in sunflower production. The study indicates that the determination coefficient (r/sup 2/) derived from Cobb-Douglas production function was significant at 0.01 level and the elasticity coefficients of the variables (except chemical fertilizer) were found beta i positive in derived equation. It was determined that the variable of herbicide cost had the highest value of the marginal effectiveness coefficients and none of the variables was used at economically optimal level in the study area. When the Marginal Technical Substitution and the Price Rates were taken into consideration, it was noted that only the seed cost/hoeing cost was closest to economically optimum level (1.10). According to stepwise analysis the Land Renting Value was determined as the most important variable in sunflower production. (author)

    In this study, a new formula based on meteorological and geographical data was developed to determine the solar-energy potential in Turkey using artificial neural-networks (ANNs). Scaled conjugate gradient (SCG) and Levenberg-Marquardt (LM) learning algorithms and a logistic sigmoid transfer function were used in the network. Meteorological data for the last four years (2000 → 2003) from 18 cities (Bilecik, Kirsehir, Akhisar, Bingoel, Batman, Bodrum, Uzunkoeprue, Sile, Bartin, Yalova, Horasan, Polatli, Malazgirt, Koeycegiz, Manavgat, Doertyol, Karatas and Birecik) spread over Turkey were used as data in order to train the neural network. Meteorological and geographical data (latitude, longitude, altitude, month, mean sunshine duration, and mean temperature) were used in the input layer of the network. Solar radiation is the output layer. One-month test data for each city was used, and these months data were not used for training. The results show that the maximum mean absolute percentage error (MAPE) was found to be 3.448% and the R 2 value 0.9987 for Polatli. The best approach was found for Kirsehir (MAPE=1.2257, R 2 =0.9998). The MAPE and R 2 for the testing data were 3.3477 and 0.998534, respectively. The ANN models show greater accuracy for evaluating solar-resource possibilities in regions where a network of monitoring stations has not been established in Turkey. This study confirms the ability of the ANN to predict solar-radiation values precisely

  10. COMPETITIVENESS OF DEFENSE INDUSTRY IN TURKEY

    2010-01-01

    Full Text Available Turkey has created some opportunities for the organisations in the defense industry to generate a suitable business and to ensure its sustainability. The domestic coverage ratio of defense system need in 2010 is aimed as 50%. To achieve this target depends on the defense industry competitiveness. In this study, the development plans, strategies and foreign trade are examined. Its contribution which has an important place in the research and development investment, is not at the level expected in Turkey’s economy. Turkey occupies 47th position in World Competitiveness Scoreboard, and 61st position in Global Competitiveness Index in 2009. The index factors are investigated to understand the competitiveness according to the Porter’s diamond model, applied in Turkey for the first time. As a result, the competitiveness analysis of Turkish defense industry is carried out and its global place and competitive advantage are exposed. Therefore, a framework is made to introduce a guide for decision-making by using a widely-accepted model, and to contribute to the plans and strategies

    To identify the prevalence and sources of sexual harassment against nurses in Turkey, its consequences, and factors affecting harassment experiences. Descriptive survey. Participants (N=622) were selected from nurses working in eight Ministry of Health hospitals in Turkey. Participants were surveyed with a Sexual Harassment Questionnaire, consisting of the sociodemographic characteristics of participants, types of sexual harassment, sources, feelings, ramifications, and ways to cope with sexual harassment behaviors. Frequency and percentage distributions, chi-square, and logistic regression were used for data analysis. The results showed 37.1% of participants had been harassed sexually. Physicians were identified as the primary instigators of sexual harassment. The most common reactions against harassers were anger and fear; frequently reported negative effects of sexual harassment were disturbed mental health function, decline in job performance, and headache. "Did nothing" was the coping method used most commonly by the nurses. About 80% of sexually harassed nurses did not report the incident of sexual harassment to hospital administration. The lower working status and power of nurses in the workplace, poor working conditions in healthcare settings, and insufficient administrative mechanisms, including the present law and regulations against sexual harassers, were identified as important factors in the work environment in Turkey.

  12. Detailed sedimentology and geomorphology elucidate mechanisms of formation of modern and historical sequences of minor moraines in the European Alps

    2016-04-01

    Suites of closely-spaced minor moraines may help further understanding of glacier retreat and predict its geomorphological effects through the observations of moraine formation on short timescales. This research is common in lowland, maritime settings (Sharp, 1984; Boulton, 1986; Krüger, 1995; Reinardy et al., 2013), but remains sparse in high-mountain settings (Hewitt, 1967; Ono, 1985; Beedle et al., 2009; Lukas, 2012). This research presents detailed sedimentological and geomorphological research on minor moraines at two high-mountain settings in the Alps: Silvrettagletscher, Switzerland, as a modern setting and Schwarzensteinkees, Austria, as a historical setting. Geomorphological investigations included mapping and measurements through field observations and assessing aerial imagery. Additionally, terrestrial laser scanning and ground-penetrating radar data were collected in the Schwarzensteinkees foreland. Detailed sedimentological investigations followed excavation of seven moraines at Silvrettagletscher and five moraines at Schwarzensteinkees and include multiple scales of observation and measurements to support interpretations of sediment transport and deposition (e.g. Evans and Benn, 2004). The modern moraines at Silvrettagletscher, in the immediately proglacial foreland, have been forming since before 2003. Four mechanisms of formation show distinct sedimentological signatures: formerly ice-cored moraines (e.g. Kjær & Krüger, 2001; Lukas, 2012; Reinardy et al., 2013) , push moraine formation on a reverse bedrock slope (e.g. Lukas, 2012), push moraine formation incorporating sediments deposited in a former proglacial basin, and basal freeze-on (e.g. Andersen & Sollid, 1971; Krüger, 1995; Reinardy et al., 2013). Schwarzensteinkees still exists but is currently restricted to steeply-dipping bedrock slabs above the main valley. This study therefore investigates the moraines in the foreland that formed between approximately 1850 and 1930. The minor

    2017-01-01

    We present a case study from New York, USA, of the use of structured decision making (SDM) to identify fall turkey harvest regulations that best meet stakeholder objectives, in light of recent apparent declines in abundance of wild turkeys in the northeastern United States. We used the SDM framework to incorporate the multiple objectives associated with turkey hunting, stakeholder desires, and region-specific ecological and environmental factors that could influence fall harvest. We identified a set of 4 fall harvest regulations, composed of different season lengths and bag limits, and evaluated their relative achievement of the objectives. We used a stochastic turkey population model, statistical modeling, and expert elicitation to evaluate the consequences of each harvest regulation on each of the objectives. We conducted a statewide mail survey of fall turkey hunters in New York to gather the necessary information to evaluate tradeoffs among multiple objectives associated with hunter satisfaction. The optimal fall harvest regulation was a 2-week season and allowed for the harvest of 1 bird/hunter. This regulation was the most conservative of those evaluated, reflecting the concerns about recent declines in turkey abundance among agency wildlife biologists and the hunting public. Depending on the region of the state, the 2-week, 1-bird regulation was predicted to result in 7–32% more turkeys on the landscape after 5 years. The SDM process provided a transparent framework for setting fall turkey harvest regulations and reduced potential stakeholder conflict by explicitly taking the multiple objectives of different stakeholder groups into account.

  14. A snapshot of geothermal energy potential and utilization in Turkey

    2009-01-01

    Turkey is one of the countries with significant potential in geothermal energy. It is estimated that if Turkey utilizes all of her geothermal potential, she can meet 14% of her total energy need (heat and electricity) from geothermal sources. Therefore, today geothermal energy is an attractive option in Turkey to replace fossil fuels. Besides, increase in negative effects of fossil fuels on the environment has forced many countries, including Turkey, to use renewable energy sources. Also, Turkey is an energy importing country; more than two-thirds of her energy requirement is supplied by imports. In this context, geothermal energy appears to be one of the most efficient and effective solutions for sustainable energy development and environmental pollution prevention in Turkey. Since geothermal energy will be used more and more in the future, its current potential, usage, and assessment in Turkey is the focus of the present study. The paper not only presents a review of the potential and utilization of the geothermal energy in Turkey but also provides some guidelines for policy makers. (author)

    Full Text Available South Caucasus throughout history was at the epicenter of clashes of different religions, civilizations, nations and states. At present moment the interests of both regional (Turkey, Iran and global actors (the United States, NATO, the EU, Russia and others. intersect in the region. Global transformations, changing power relations in international relations have their direct influence on the political processes taking place in the region. These processes are also linked with the activities of Turkey, which aspire to regional leadership. It is Georgia, which serves as a corridor between Turkey and states of Central Asia and the South Caucasus. Turkey spreads its influence in Georgia in almost all areas using economic, military and political tools, as well as the Russian-Georgian deteriorated relations. To achieve its goals, Turkey is actively pursuing a strategy of "soft power", which further strengthens its influence in the country. Public diplomacy is a part of soft power, which also ensures the formation of a positive and attractive image of Turkey in Georgia. This article investigates the contemporary policy of "soft power" of Turkey towards Georgia. It analyses the basic tools, institutions and the direction of this policy, actively implemented by the Republic of Turkey. Particular attention is paid to the activities of the Gulen Movement in Georgia. The author makes general conclusions regarding the effectiveness of this policy.

    Yuksek, Omer; Komurcu, Murat Ihsan; Yuksel, Ibrahim; Kaygusuz, Kamil

    2006-01-01

    The inherent technical, economic and environmental benefits of hydroelectric power, make it an important contributor to the future world energy mix, particularly in the developing countries. These countries, such as Turkey, have a great and ever-intensifying need for power and water supplies and they also have the greatest remaining hydro potential. From the viewpoint of energy sources such as petroleum and natural gas, Turkey is not a rich country; but it has an abundant hydropower potential to be used for generation of electricity and must increase hydropower production in the near future. This paper deals with policies to meet the increasing electricity demand for Turkey. Hydropower and especially small hydropower are emphasized as Turkey's renewable energy sources. The results of two case studies, whose results were not taken into consideration in calculating Turkey's hydro electric potential, are presented. Turkey's small hydro power potential is found to be an important energy source, especially in the Eastern Black Sea Region. The results of a study in which Turkey's long-term demand has been predicted are also presented. According to the results of this paper, Turkey's hydro electric potential can meet 33-46% of its electric energy demand in 2020 and this potential may easily and economically be developed

    A transition from microbanded Kuruman to granular Griquatown iron-formation is described in terms of sedimentological, petrographic, and geochemical characteristics, as well as whole rock carbon and oxygen isotopic compositions. Five major lithofacies are present in the Kuruman-Griquatown transition zone. The lithofacies are arranged in an upward coarsening sequence. It is concluded that the coarsening upward microbanded-granular iron-formation units in the Kuruman-Griquatown sequence represent shallowing upward storm-dominated deposits. 2 refs

    Full Text Available The topic of article is bilateral economical and foreign trade relations between Turkey, which has started to apply outward-oriented economic policies since globalization and Moldova, which has done market transition after breaking up with the Soviet Union. Within this frame, the subject of article has been searched in depth as follows: general overview of Turkey’s economic relations, overall picture of Moldovan-Turkish relations, short exposition of Moldovan economy and bilateral economic and foreign trade relations of Moldova and Turkey. The topic of article is a current issue. Because Moldova, which is closed to Turkey in terms of geography, culture and history always has been an attractive country politico-economically for Turkey since its independence. Bilateral economic relations starting with shuttle trade have formalized and further developed and Turkey became as one of top ten biggest economic and trade partner of Moldova. On this basis, the aim of study is to elucidate foreign trade of Turkey with Moldova and to compare performances of Turkey by years and by other countries, which have remarkable domination in Moldovan market. Within this scope, bilateral trade volume of Moldova and Turkey has increased year by year considering the past decade, which makes Turkey as the 7th largest import and 8th export partner of Moldova. Turkey aims to be one of the first three biggest economic partner of Moldova after entry into force of Free Trade Agreement (FTA, which was signed by both countries in 2014 to increase foreign trade volume up to 1 billion US dollars.

    Samples collected in 2008 and 2009, from 49 turkey flocks of 6 to 43 days in age and presenting clinical signs of enteric disease and high mortality, were tested by polymerase chain reaction and reverse transcription-polymerase chain reaction for the presence of viruses currently associated with enteric disease (ED) syndromes: astrovirus, reovirus, rotavirus, coronavirus, adenovirus, and parvovirus. Turkey astroviruses were found in 83.67% of the cases and turkey astrovirus 2 (TAst-2) in 26.53%. The investigations directly demonstrated the high prevalence of turkey parvovirus (TuPV) in 23 flocks (46.9%) experiencing signs of ED, making this pathogen the second most identified after astroviruses. Phylogenetic analysis on a 527 base pair-long region from the NS1 gene revealed two main clusters, a chicken parvovirus (ChPV) and a TuPV group, but also the presence of a divergent branch of tentatively named "TuPV-like ChPV" strains. The 23 Hungarian TuPV strains were separately positioned in two groups from the American origin sequences in the TuPV cluster. An Avail-based restriction fragment length polymorphism assay has also been developed for the quick differentiation of TuPV, ChPV, and divergent TuPV-like ChPV strains. As most detected enteric viruses have been directly demonstrated in healthy turkey flocks as well, the epidemiology of this disease complex remains unclear, suggesting that a certain combination of pathogens, environmental factors, or both are necessary for the development of clinical signs.

    Full Text Available Background: The research and published literatüre on Roma health in Turkey is much more limited than in other European countries. Among these, there are hardly any published literature focusing on the health status, health indicators and health behaviors. Aims: The aim of this research is to describe the perceptions of health-related concepts and access and the use of health services and social determinants of the health of Roma people in Turkey. Study Design: Descriptive qualitative survey. Methods: The participants were chosen by random sampling. The semi-structured interview topic guide was developed from sources such as advice from the Romani community leaders, published evidence and personal experience from previous work with Roma communities. Non-directive open ended questions allowed the exploration of their health status, how they conceptualize health and disease, their level of awareness on the impact of social determinants of health, on their health status and the access and use of health services. The data analysis was based on grounded theory. Analysis proceeded in four steps: 1. Reading and examining the transcripts separately using open coding, 2. Extracting the key words and codes from the transcripts and sorting them into categories, 3. Rereading the transcripts by using selective coding, and 4. Examining the categories derived from the open coding systematically and determining the concepts summarizing the material. Results: The survey results are compatible with the existing literature on Roma health and reveal that 1 there is a tight link between the lack of social determinants of health and the poor health status of Roma people 2 socioeconomic factors and cultural norms of the ethnic minority are suspicious factors 3 comparative and systematic research is needed to illuminate the actual health gaps and causal factors for them. Conclusion: The research proves that the need for comparative and systematic research in Turkey to

    Although intimate partner violence (IPV) is an important problem that threatens women’s health, very few studies focus on the victim—perpetrator relationship or examine this relationship across Turkey. The aim of this study is to contribute to a better understanding of femicide cases in Turkey and to describe the socio-demographic, clinical, forensic, and criminological characteristics of femicide victims and offenders. This study analysed 162 femicide cases that occurred in 12 cities in Turkey from 1 January 2000 to 31 December 2010. Eighty women were killed by their partners (classified as intimate partner femicide, IPF), and 81 women were killed by one of their relatives, friends, or strangers (classified as non-intimate partner femicide, non-IPF). According to our results, the typical IPF victim is of child-bearing age, does not have a paid job, is married or divorced, is killed in a domestic setting due to injuries to the thorax or abdomen produced by an edged/pointed weapon or firearm, and is possibly a victim of overkill. The typical IPF perpetrator is close to his victim’s age, has a paid job, has no mental disability, owns a gun, and has threatened his partner or ex-partner previously because of jealousy/infidelity/honour or separation. The typical non-IPF victim is very similar to the IPF victim; however, her marital status can be single, married or divorced, and she is commonly killed by a relative. The surveillance and screening of femicide and IPV is an important step when analysing and attempting to prevent femicide. Second, the training and sensitization of health professionals are important. Moreover, health staff should be encouraged to participate in advocacy interventions. Third, gun ownership must be brought under control. PMID:28832596

    The Gulf of Gökova is located in southwestern Turkey near the Aegean Sea and surrounded by Datça Peninsula to the south, the island of Kos to the west and Bodrum Peninsula to the north. The Bodrum peninsula with a population of one million in summer season is one of the most populated touristic centers of Turkey. This region is also surrounded by numerous active seismic entities such as Ula-Ören Fault Zone, Gökova Graben etc.. and demonstrates high seismic hazard. In the past, many destructive earthquakes have occurred in southwestern Turkey. One of the destructive historical earthquakes is 1493 Kos event (Mw=6.9) caused heavy damage in Bodrum. In the instrumental period seismic activity in the Gökova region includes the Ms>6.0 earthquakes of 23 April 1933 (Ms=6.4), 23 May 1941 (Ms=6.0), 13 December 1941 (Ms=6.5) events. Intense earthquake activity (Mw5+) occurred in Gulf of Gökova in August 2004 and January 2005. Considering the high seismicity and population of this region, a strong ground motion monitoring system stationed in dense settlements in the Bodrum Peninsula: Bodrum, Turgutreis, Yalıkavak, Çiftlik and Ortakent was deployed on June 2015. The network consists of 5 strong motion recorders, has been set up with the aim of monitoring of regional earthquakes, collecting accurate and reliable data for engineering and scientific research purposes, in particular to provide input for future earthquake rapid reporting and early warning implementation projects on urban environments in the Bodrum peninsula and the surrounding areas. In this poster presentation, we briefly introduce the Bodrum Network and discuss our future plans for further developments.

    Allergic diseases constitute a significant health problem in Turkey. According to a recent multicenter study, which used the ISAAC questionnaire, the mean prevalence of wheezing, rhinoconjunctivitis, and eczema in 10-yr-old school children during the past year was 15.8%, 23.5%, and 8.1%, respectively. A healthcare level system, regulated by Ministry of Health, is available in Turkey. Pediatric allergists and pediatric immunologists provide patient care at the tertiary level. Currently, 48 centers deliver care for allergic and immunologic diseases in children. There are 136 pediatric and 61 adult allergists/immunologists. Although the number of allergy/clinical immunology specialists is limited, these centers are capable of delivering many of the procedures required for the proper management and diagnosis of allergy/immunology. Pediatric allergy and/or immunology is a subspecialty lasting 3 yr and follows a 4-yr pediatric specialist training. Fellow training involves gaining knowledge in basic and clinical allergy and immunology as well as the performance and interpretation of laboratory procedures in the field of allergy and clinical immunology. The Turkish National Society of Allergy and Clinical Immunology (TNSACI) was officially established in 1989 and currently has 356 members. The society organizes a national congress annually and winter schools for fellowship training as well as training courses for patients and their relatives. TNSACI also has a strong representation in European Academy of Allergy and Clinical Immunology (EAACI) and European Society for Immunodeficiencies (ESID) through its participation in the executive committee, consensus reports, and initiatives in the diagnosis of allergic and immunologic diseases of children. The 30th Congress of the EAACI is also due to be held in Istanbul, Turkey, between June 11 and 15, 2011. © 2011 John Wiley & Sons A/S.

    Full Text Available In this study dairy farming activities in Turkey are employed to prove that small-scale agricultural production is disappearing rapidly due to costly investment and mechanization needs. For that purpose the cost structure and the investment needs in starting a dairy farm are analyzed. The results show that the capital requirements of building a dairy farm with optimal capacity are hard to reach for small farmers unless a system of marketing and production agricultural cooperatives and/or institutions are organized.

    Full Text Available Ethnic Tourism: An Example from Istanbul, Turkey. Globalization has not only produced a trend towards economic integration and cultural homogenization but has also encouraged the preservation of local diversity and of multiculturalism. Whereas in the past ethnic or religious minorities were seen as a threat to the territorial unity of the country, today, increasingly countries are promoting ethnicities to attract tourists. Ethnic tourism is an alternative form of tourism that relies on attracting tourists to see sites connected to the cultural and historical heritage of ethnic minorities. This study explores the potential for ethnic tourism development in Istanbul, a city with a multicultural past and great heritage attractions.

    2001-12-01

    The important heterogeneity of neritic carbonates reflects: 1 - the facies characteristics of the initial sediments, linked with the diversity of sedimentation environments, and 2 - the post-sedimentation diagenesis characteristics. The aim of this work is to explore this heterogeneity using the δ 18 O isotopic signal. A three step pluri-disciplinary approach with different observation scales is established: 1 - a sedimentology study (facies inventory, paleo-environment variations, stratigraphic cycles), 2 - an inventory and chronology of the diagenesis phases and products which have modified he initial sediments, and 3 - a geochemical approach based on the δ 18 O signal. This last step combines ionic microprobe measurements performed on separated phases and measurements performed on the whole rock carbonated phase. The carbonate formations under study correspond to the HTM102 borehole made by the ANDRA in the Malm of the eastern edge of the Paris basin. For the stratigraphic approach, some field analogues have been studied (Pagny-sur-Meuse and Gudmont-Villiers sections). (J.S.)

    Intraslope lobe deposits provide a process record of the infill of accommodation on submarine slopes and their recognition enables the accurate reconstruction of the stratigraphic evolution of submarine slope systems. Extensive exposures of discrete sand-prone packages in Units D/E and E, Fort Brown Formation, Karoo Basin, South Africa, permit analysis of the sedimentology and stacking patterns of three intraslope lobe complexes and their palaeogeographic reconstruction via bed-scale analysis and physical correlation of key stratal surfaces. The sand-prone packages comprise tabular, aggradationally to slightly compensationally stacked lobe deposits with constituent facies associations that can be attributed to lobe axis, lobe off-axis, lobe-fringe and distal lobe-fringe environments. Locally, intraslope lobe deposits are incised by low aspect ratio channels that mark basinward progradation of the deepwater system. The origin of accommodation on the slope for lobe deposition is interpreted to be due to differential compaction or healing of scars from mass wasting processes. The stacking patterns and sedimentary facies arrangement identified in this study are distinct from those of more commonly recognized basin-floor lobe deposits, thereby enabling the establishment of recognition criteria for intraslope lobe deposits in other less well exposed and studied fine-grained systems. Compared to basin floor lobes, intraslope lobes are smaller in volume, influenced by higher degrees of confinement, and tend to show aggradational stacking patterns.

    1976-01-01

    This study integrates stratigraphical, structural, petrological, and mineralogical data with a comprehensive set of sedimentological data to synthesize a model that describes the genesis of the Vaal Reef placer. Results show that the Vaal Reef placer was a shoreline feature of the Upper Witwatersrand Basin and that its deposition was controlled, firstly, by the major structure of the basin and, secondly, by a minor transverse synclinal structure that induced an entry point. New geological aspects that have emerged are, firstly, that the tectonic framework during Vaal Reef Stage deposition was very much simpler than previously envisaged. There is no evidence of subsidiary incipient basining. Secondly, modifications of previous conceptual models are made which emphasize the importance that detailed dispersal patterns and subtle paleosurface forms had on heavy mineral distribution in the distal fluviodeltaic environment of carbon-seam placers. Thirdly, sedimentary responses involving unconformities, disconformities, and accumulation are evidently related to particular entry points and may not be specifically correlated beyond their local tectonic framework. Fourthly, tectonic instability and basining is dated between Lower and Upper Ventersdorp System time and certainly before deposition of the Transvaal System

    The basement of the Ganga basin in the Himalayan foreland is criss-crossed by several faults, dividing the basin into several sub-blocks forming horsts, grabens, or half-grabens. Tectonic perturbations along basement faults have affected the fluvial regime and extent of sediment fill in different parts of the basin during Late Quaternary. The East Patna Fault (EPF) and the West Patna Fault (WPF), located in Sone-Ganga alluvial tract in the southern marginal parts of Middle Ganga Plain (MGP), have remained tectonically active. The EPF particularly has acted significantly and influenced in evolving the geomorphological landscape and the stratigraphic architecture of the area. The block bounded by the two faults has earlier been considered as a single entity, constituting a half-graben. The present investigation (by morpho-stratigraphic and sedimentologic means) has revealed the existence of yet another fault within the half-graben, referred to as Bishunpur-Khagaul Fault (BKF). Many of the long profile morphological characters (e.g., knick-zone, low width-depth ratio) of the Sone River at its lower reaches can be ascribed to local structural deformation along BKF. These basement faults in MGP lie parallel to each other in NE-SW direction.

    2013-09-01

    Full Text Available A 2D depth average model has been used to simulate water and sediment flow in the Brenta River so as to interpret channel changes and to assess model predictive capabilities. The Brenta River is a gravel bed river located in Northern Italy. The study reach is 1400 long and has a mean slope of 0.0056. High resolution digital terrain models has been produced combining laser imaging detection and ranging data with colour bathymetry techniques. Extensive field sedimentological surveys have been also carried out for surface and subsurface material. The data were loaded in the model and the passage of a high intense flood (R.I. > 9 years was simulated. The model was run under the hypothesis of a substantial equilibrium between sediment input and transport capacity. In this way, the model results were considered as a reference condition, and the potential trend of the reach was assessed. Low-frequency floods (R.I. » 1.5 years are expected to produce negligible changes in the channel while high floods may focalize erosion on banks instead than on channel bed. Furthermore, the model predicts well the location of erosion and siltation areas and the results promote its application to other reaches of the Brenta River in order to assess their stability and medium-term evolution.

    Depositional models of ancient lakes in thin-skinned retroarc foreland basins rarely benefit from appropriate Quaternary analogues. To address this, we present new stratigraphic, sedimentological and geochemical analyses of four radiocarbon-dated sediment cores from the Pozuelos Basin (PB; northwest Argentina) that capture the evolution of this low-accommodation Puna basin over the past ca. 43 cal kyr. Strata from the PB are interpreted as accumulations of a highly variable, underfilled lake system represented by lake-plain/littoral, profundal, palustrine, saline lake and playa facies associations. The vertical stacking of facies is asymmetric, with transgressive and thin organic-rich highstand deposits underlying thicker, organic-poor regressive deposits. The major controls on depositional architecture and basin palaeogeography are tectonics and climate. Accommodation space was derived from piggyback basin-forming flexural subsidence and Miocene-Quaternary normal faulting associated with incorporation of the basin into the Andean hinterland. Sediment and water supply was modulated by variability in the South American summer monsoon, and perennial lake deposits correlate in time with several well-known late Pleistocene wet periods on the Altiplano/Puna plateau. Our results shed new light on lake expansion–contraction dynamics in the PB in particular and provide a deeper understanding of Puna basin lakes in general.

    1994-05-01

    A well exposed outcrop in the Kayenta Formation (Lower Jurassic) in southwestern Colorado was examined in order to delineate the stratigraphy in the subsurface and test the usefulness of ground-probing radar (GPR) in three-dimensional architectural studies. Two fluvial styles are present within the Kayenta Formation. Sandbodies within the lower third of the outcrop are characterized by parallel laminations that can be followed in the cliff-face for well over 300 m. These sandbodies are sheet-like in appearance, and represent high-energy flood deposits that most likely resulted from episodic floods. The remainder of the outcrop is characterized by concave-up channel deposits with bank-attached and mid-channel macroforms. Their presence suggests a multiple channel river system. The GPR data collected on the cliff-top, together with sedimentological data, provided a partial three-dimensional picture of the paleo-river system within the Kayenta Formation. The 3-D picture consists of stacked channel-bar lenses approximately 50 m in diameter. The GPR technique offers a very effective means of delineating the subsurface stratigraphy. Its high resolution capabilities, easy mobility, and rapid rate of data collection make it a useful tool. Its shallow penetration depth and limitation to low-conductivity environments are its only drawbacks.

    Detailed sedimentological and geochemical records across the Permian-Triassic boundary (PTB) in five offshore wells of the central Persian Gulf served to interpret the end-Permian sea-level change in this region. A decrease in sea level at the PTB was established by petrographical and geochemical study of the boundary. Thin sections showed that Upper Permian strata are composed of dolomite with minor anhydrite, changing into limestone in Lower Triassic sediments. Brine dilution toward the boundary supports sea-level fall in the Permian-Triassic transition, reflected by a decrease in anhydrite content and a shallowing-upward trend from lagoonal to peritidal facies. Isotopic changes at the boundary are in favor of sea-level fall. Changes in both carbon (from about 4 to -1‰) and oxygen (from 2 to -5‰) stable isotopes show negative excursions. The shift in carbon isotope values is a global phenomenon and is interpreted as resulting from carbonate sediment interaction with 12C-rich waters at the end-Permian sea-level fall. However, the oxygen isotope shift is attributed to the effect of meteoric waters with negative oxygen isotope values. The increase in strontium isotope ratios is also consistent with the high rate of terrestrial input at the boundary. The effect of meteoric conditions during diagenesis is evident from vuggy and moldic porosities below the PTB. The following transgression at the base of the Triassic is evident from the presence of reworked fossils and intraclasts resulting from deposition from agitated water.

    Directory of Open Access Journals (Sweden)

    Moretti Massimo

    2016-06-01

    Full Text Available Beach sands from the Rosa Marina locality (Adriatic coast, southern Italy were analysed mainly microscopically in order to trace the source areas of their lithoclastic and bioclastic components. The main cropping out sedimentary units were also studied with the objective to identify the potential source areas of lithoclasts. This allowed to establish how the various rock units contribute to the formation of beach sands. The analysis of the bioclastic components allows to estimate the actual role of organisms regarding the supply of this material to the beach. Identification of taxa that are present in the beach sands as shell fragments or other remains was carried out at the genus or family level. Ecological investigation of the same beach and the recognition of sub-environments (mainly distinguished on the basis of the nature of the substrate and of the water depth was the key topic that allowed to establish the actual source areas of bioclasts in the Rosa Marina beach sands. The sedimentological analysis (including a physical study of the beach and the calculation of some statistical parameters concerning the grain-size curves shows that the Rosa Marina beach is nowadays subject to erosion.

    1986-01-01

    This paper summarizes sedimentological and hydrological studies at a salt marsh site on the north bank of the River Esk near Ravenglass which have a bearing on the fate of the low-level radioactive effluent from the reprocessing facility at Sellafield, Cumbria. A range of techniques has been used including electromagnetic distance measurement (EDM) and pore water pressure studies. The results show that: (a) Over a two-year period there were no significant net changes in salt marsh creek level, although shorter-term (probably seasonal) fluctuations, of the order of 2 cm, occurred. These were attributed to expansion of clay particles during the winter months. Nearby, however, there were vertical changes of the order of 1 m due to erosion. (b) Pore water pressures indicated a dynamic situation with very rapid responses both to tidal fluctuations and to rainfall. During neap tides there was clear evidence for water seeping upwards from the underlying clay/sand interface. Shortlived radionuclides ( 95 Zr/ 95 Nb and 106 Ru) were detected in this zone. (c) soil polygons, once initiated by desiccation, thereafter provide preferential routes for water (and radionuclides) to the sub-surface sediment. These, and other results, are discussed in the context of previous studies. It is concluded that the complexity of the estuarine environment results in most data being site specific. (author)

    High-resolution sedimentological and geochemical records were obtained from two sediment cores recovered by the French R/V Marion Dufresne during the INDIEN-SUD-ACC cruises near the sub-Antarctic Kerguelen Islands (49°S). This area is ideal to record past oceanic and atmospheric changes in the Southern Ocean because they are currently located in the northern branch of the Antarctic Circumpolar Current and under the direct influence of Southern Hemisphere Westerly wind belt. This study focuses on the last termination, with specific emphasis on the impact of severe climatic events (Heinrich Stadial 1, Antarctic Cold Reversal, Younger Dryas) onto the ocean-atmospheric exchange. Results indicates that most of the sediment is derived from the Kerguelen Plateau, characterized by high smectite content. Periodically, a minor contribution of Antarctica is noticeable. In particular, illite variations suggest fast and short northward incursions of Antarctic Bottom Water, probably formed in the Prydz Bay during the last glaciation. Grainsize repartition combined to magnetic parameters show a southward migration of the ACC and the fronts associated from the beginning of the deglaciation, which is consistent with Southern Hemisphere climate variations. On the opposite, it highlights an asynchronous decrease of the ACC strength, with a large drop during the Antarctic Cold Reversal when atmospheric CO2 increase was slowed down. Thus, at least in the studied area, the ACC strength and the Antarctic Climate were not synchronous during the last deglaciation.

    2017-10-01

    The main aim of this paper is to determine the depositional environments of an Upper-Eocene coarse-grained clastic succession in the Buda Hills, Hungary. First of all, we measured some commonly used parameters of samples (size, amount, roundness and sphericity) in a much more objective overall and faster way than with traditional measurement approaches, using the newly developed Rock Analyst application. For the multivariate data obtained, we applied Combined Cluster and Discriminant Analysis (CCDA) in order to determine homogeneous groups of the sampling locations based on the quantitative composition of the conglomerate as well as the shape parameters (roundness and sphericity). The result is the spatial pattern of these groups, which assists with the interpretation of the depositional processes. According to our concept, those sampling sites which belong to the same homogeneous groups were likely formed under similar geological circumstances and by similar geological processes. In the Buda Hills, we were able to distinguish various sedimentological environments within the area based on the results: fan, intermittent stream or marine.

    Cole, D.I.

    1980-08-01

    The sedimentology of two uranium-bearing sandstones on the Waterval portion of the farm Brandewyns Gat 214 was studied by means of 36 vertical profiles measured across, through and adjacent to 4 mineralised deposits. The vertical profiles basically consist of a succession of sedimentary facies. A total of 19 facies was recognised within the fluvial sandstone sequence according to the criteria of grain-size and sedimentary structure. Transitions between the facies were subjected to a Markov chain analysis in order to delineate Markov-dependent transitions. Uranium mineralisation occurs mostly within the lower half of the fluvial sandstone sequence and is confined to the coarser-grained sedimentary facies. These facies probably acted as suitable aquifers for the transport of uraniferous solutions and permeability differences between the sandstone and the underlying mudstone and siltstone must have restricted these solutions to the lower half of the channel sandstone. The massive mudstone facies contains 13 per cent of the total cumulative thickness of mineralisation. This mineralisation probably originated from synchronously deposited tuffaceous material. Subsequent migration of uraniferous solutions may have concentrated the uranium

    Full Text Available This paper presents a novel 2D-depth average model especially developed for gravel-bed rivers, named Lican-Leufú (Lican=pebble and Leufu=river, in Mapuche’s language, the native inhabitants of Central Patagonia, Argentina. The model consists of three components: a hydrodynamic, a sedimentological, and a morphological model. The flow of water is described by the depth-averaged Reynolds equations for unsteady, free-surface, shallow water flows. It includes the standard k-e model for turbulence closure. Sediment transport can be divided in different size classes (sand-gravel mixture and the equilibrium approach is used for Exner’s equation. The amour layer is also included in the structure of the model and the surface grain size distribution is also allowed to evolve. The model simulates bank slides that enable channel widening. Models predictions were tested against a flume experiment where a static armour layer was developed under conditions of sediment starvations and general good agreements were found: the model predicted adequately the sediment transport, grain size of transported material, final armour grain size distribution and bed elevation.

    2009-01-01

    Decentralized wind, hydropower, biogas and biomass, geothermal, solar thermal and solar electricity energy systems are the most commonly found renewable energy technologies promoted for rural energy supply within sustainable developments programs. They are, therefore, seen to have a central place in the practice of sustainable development and in allowing less development countries to bypass the environmentally damaging fossil fuel intensive paths made by industrialized countries. On the political front, many less development countries are critical of pressure on them to adopt environmental energy technologies. Turkey is situated the meeting point of three continents (Asia, Europe and Africa) and stands as a bridge between Asia and Europe. The country is located in southeastern Europe and southwestern Asia. As Turkey's economy has expanded in recent years, the consumption of primary energy has increased. Presently in order to increase the energy production from domestic energy resources, decrease the use of fossil fuels as well as reduce of green house gas emissions different renewable energy sources are used for energy production in Turkey. The share of energy production from renewable energy sources has increased during the last 10 years. Turkey must import most of the energy to meet her needs. Turkey also has a large potential for renewable energies. The lack of knowledge about renewable energy technologies by most policy-makers, potential consumers, and energy firm managers has played against renewable energy developments. The paper presents renewable energy used in Turkey and Europe Union and evaluation of the market conditions and barriers of renewable energy use in Turkey. (author)

    Turkey is an important candidate to be the 'energy corridor' in the transmission of the abundant oil and natural gas resources of the Middle East and Middle Asia countries to the Western market. Furthermore, Turkey is planning to increase its oil and gas pipeline infrastructure to accommodate its increased energy consumption. Naturally, Turkish natural gas usage is projected to increase remarkably in coming years, with the prime consumers, expected to be industry and power plants. Energy demand of Turkey is growing by 8% annually, one of the highest rates in the world. In addition, natural gas consumption is the fastest growing primary energy source in Turkey. Gas sales started at 0.5 bcm (billion cubic meters), in 1987 and reached approximately 22 bcm in 2003. This article deals with energy policies and natural gas consumption of Turkey. Besides modernization of present lines and realization of capacity increase, new lines will also be needed. In this context, Turkey, due to its geographical location is, in an important position to vary European supply. Therefore, Turkey's role as a transitory area gains importance

  2. Hydropower and biomass as renewable energy sources in Turkey

    Kaygusuz, K.

    2001-01-01

    When talking about renewable energy sources today, the most important and economical energy sources for Turkey are hydropower and biomass.The present study gives a review of production, consumption, and economics of hydropower and biomass as renewable energy sources in Turkey. Turkey has a total gross hydropower potential of 433 GW, but only 125 GW of the total hydroelectric potential of Turkey can be economically used. By the commissioning of new hydropower plants, which are under construction, 36% of the economically usable potential of the country could be tapped. On the other hand, biomass (wood and wastes) energy is the second most important renewable energy source for Turkey. However, the biomass energy sources of Turkey are limited. In 1998, the biomass share of the total energy consumption of the country is 10%. In this study, the potential of important biomass energy sources and animal solid wastes of the country were determined. The effects of hydropower and biomass usage on the environment were also discussed. Considering total cereal products and fatty seed plants, approximately 50-60 million tons per year of biomass and 8-10 million tons of solid matter animal waste are produced, and 70% of total biomass is seen as being usable for energy. Some useful suggestions and recommendations are also presented. The present study shows that there is an important potential for hydropower and biomass energy sources in Turkey. (author)

  3. DEVELOPMENT OF ISLAMIC BANKING IN TURKEY

    2015-12-01

    Full Text Available While the financial world is still dominated by conventional banks, based on western economic principles, the number of Islamic banks is on the rise. Islamic banks have originated from colonial India as a response of the Muslims to the British who attempted to westernize their society. Other similar financial operations based on Islamic Law (Shari’a were established in Pakistan, Malaysia and Egypt to facilitate access of rural poor to interest-free loans. However, being unprofitable, these operations did not survive for very long. Islamic banks, unlike conventional banks, are not based on interest and conduct their business in accordance with a wide array of ethical and moral issues. The modern phase of Islamic banking started in the 1970s when the Islamic Development Bank was founded in Saudi Arabia. Soon after, a number of commercial banks were established in the neighboring countries. From this core, over the last four decades, Islamic finance and banking has spread across the entire Muslim world and beyond to become a global phenomenon. This study examines the development of Islamic banking in Turkey in the wider context of global expansion. Turkey is an interesting case study because, although its population is nearly 100% Muslim, it is a secular state built on the model of Western European countries. However, lately, the moderate Islamic party in power since 2002 has shown some signs of openness towards a parallel banking system based on Islamic principles.

    Human cystic echinococcosis (CE) caused by infection with a larval stage of Echinococcus granulosus is a serious public health problem in Turkey. Echinococcosis is a zoonotic disease; dogs and livestock are important hosts in transmission. The aim of this study is to evaluate the rate of CE in Kayseri Rural Area, Central Anatolia, Turkey. At the present study, we planned to evaluate the rate of CE in Kayseri rural area in Central Anatolia between 2000 and 2002. We investigated 2,242 subjects using enzyme-linked immunosorbent assay (ELISA) and indirect fluorescence antibody (IFA), and we examined the seropositivity by using Western blotting (WB). The seropositivity rate was 2.7% by ELISA and IFA. We retested seropositive serum samples and 200 seronegative sera by WB. Seropositive serum samples were studied using abdominal ultrasound and chest x-ray to confirmed the presence of hydatid cyst and we found 10 (0.5%) different localized cysts. The results of our study indicate that Kayseri rural area has a high endemicity of human CE. (author)

In that region, Gendarmarie is responsible, inter alia, combating smuggling; The region of police: General Directorate of National Police has performed its tasks, one of which is to combat smuggling in the city areas; The region of Territorial Waters: Coast Guard is related authority in territorial water for, among other things, fighting smuggling. The region of Customs: General Directorate of Customs Enforcement fulfills in these regions as the authority and responsible law enforcement agent. The main difference between GDCE and other law enforcement agencies are: GDCE is the only Administration whose main aim is to struggle against smuggling; Generally, all units conduct their operations in their responsible region, however, if it is necessary, depending on the case, an operation can be performed jointly only in another region in cooperation with the relevant agent. In that context, as far as General Directorate of Customs Enforcement is concerned, fulfilling an operation in other regions is not a legal necessity. Any units of GDCE can seize and do operation all over Turkey by itself, without any regional limitations from legislation. Organizational Structure of the Customs Administration in Turkey - The principle functions of the General Directorate of Customs are: implementation of customs policies, collection of customs taxes, inspection of passengers and goods, also, investigation of smuggling

    Full Text Available Leech enters to mouth and nose through water. Nose and nasopharynx mucosa are the most preferred places for leech attachment with epistaxis and respiratory distress symptoms. But the leeches may rarely stick deeper to trachea or esophagus which could cause hematemesis, hemoptysis and severe respiratory distress. Leech infestation can cause gastrointestinal, respiratory and genital bleeding in rare cases. Various animals such as ruminants, single-toed and carnivores, are easily infected with leeches. In May 2014, a 2-year-old turkey infected with leeches through the contaminated drinking water was referred to a veterinarian with respiratory distress symptoms, anxiety, bleeding from the mouth in Maze-Abdali Village located at 17 km from Dehloran City of Ilam Province in the west of Iran. After physical observations, a moving dark green particle was seen. Limnatis nilotica were detected after separation from the oral cavity of turkey. Respiratory distress and oral cavity bleeding should be regarded in the areas where spring and flooded water were infested with leeches. Untreated and contaminated waters consumption should be prohibited.

    Full Text Available There was a notable housing price inflation in aggregate/local levels in Turkey during the last few years. Although the country’s economic fundamentals remain strong, the probability of a housing bubble is a heated debate among market participants. This timely investigation brings greater clarity to whether the Turkish housing market is in a bubble. The study uses a multi-strand approach to dissect the bubble over the period of Jan. 2010 - Dec. 2014. First, monthly/annual price-to-income and monthly price-to-rent ratios are examined for the national Turkish as well as regional Istanbul, Izmir and Ankara housing markets. Second, an extended CASE and SHILLER (2003 model is applied assessing the interdependence between housing prices and a series of explanatory variables. Lastly, the Right Tail Augmented Dickey-Fuller (Rtadf test is performed to support the overall analysis. This study finds that neither affordability ratios nor regression estimates support the existence of the bubble in Turkey.

    Two main wastewater treatment plants in Bursa city in Turkey will start to operate and produce at least 27,000 tons of dry solids per year by the end of 2006. The purpose of this study was to investigate an economical solution to the sludge management problem that Bursa city would encounter. The general trend in Turkey is mechanical dewatering to obtain a dry solid (DS) content of 20%, and liming the mechanically dewatered sludge to reach the legal land filling requirement, 35% DS content. This study recommends limited liming and solar drying as an alternative to only-liming the mechanically dewatered sludge. Open and covered solar sludge drying plants were constructed in pilot scale for experimental purposes. Dry solids and climatic conditions were constantly measured. Faecal coliform reduction was also monitored. The specially designed covered solar drying plant proved to be more efficient than the open plant in terms of drying and faecal coliform reduction. It was found that, if the limited liming and solar drying method was applied after mechanical dewatering instead of only-liming method, the total amount of the sludge to be disposed would be reduced by approximately 40%. This would lead to a reduction in the transportation, handling, and land filling costs. The covered drying system would amortize itself in 4 years. (author)

    Food waste can be an environmental and economic problem if not managed properly but it can meet various demands of a country if it is considered as a resource. The purpose of this report is to review the existing state of the field in Turkey and identify the potential of food waste as a resource. Food loss and waste (FLW) was examined throughout the food supply chain (FSC) and quantified using the FAO model. Edible FLW was estimated to be approximately 26milliontons/year. The amount of biodegradable waste was estimated based on waste statistics and research conducted on household food waste in Turkey. The total amount of biodegradable waste was found to be approximately 20milliontons/year, where more than 8.6milliontons/year of this waste is FLW from distribution and consumption in the FSC. Options for the end-of-life management of biodegradable wastes are also discussed in this review article. Copyright © 2017 Elsevier Ltd. All rights reserved.

  10. Recent practices on wastewater reuse in Turkey.

    2005-01-01

    Reuse of wastewater for irrigational purposes in agriculture has been a widely applied practice all around the world compared to such applications in industries. In most of the developing countries, high costs of wastewater treatment stimulate the direct reuse of raw or partly treated effluent in irrigation despite the socio-cultural objections in some countries regarding religious rituals towards consuming wastewater. In Turkey, reuse applications in agriculture have been in use by indirect application by means of withdrawing water from the downstream end of treatment plants. Such practices affected the deterioration of surface water resources due to the lack of water quality monitoring and control. However, more conscious and planned reuse activities in agriculture have recently started by the operation of urban wastewater treatment plants. Turkey does not face any severe water scarcity problems for the time being, but as the water resources show the signs of water quality deterioration it seems to be one of the priority issues in the near future. The industrial reuse activities are only at the research stage especially in industries consuming high amounts of water. In-plant control implementation is the preferred effort of minimizing water consumption in such industries. The current reuse activities are outlined in the article forming an example from a developing country.

    Black Sea, Aegean, Mediterranean and Marmara Sea, which surround the Turkey, have not been examined with respect to the Geological, Geophysical and other natural sciences sufficiently. In fact, it is not attach importance the Turkish seas adequately and abandoned with respect to the scientific researches. The most important reason of this situation is the lack of the education of the Marine Sciences in the Turkish Universities. In this study, it is tried to construct a crustal structure data base of the surrounding seas of the Turkey by collecting crustal structure data sets done by different authors in different times so far. The data acquired in the base are collected from different data base sources by dragging. The Moho depth in the eastern and western basin of the Black sea is 22 km and 19 km, respectively. In the Marmara Sea the Moho depth is 24 km. The moho value in the southern Aegean is 20 km, in the northern Aegean the moho depth is 30 km. on the other hand, the moho depth value in the eastern and western basin of the Mediterranean Sea are 15-20 km and 25-30 km, respectively

    2008-12-09

    We develop individual-based movement ecology models (MEM) to explore turkey vulture (Cathartes aura) migration decisions at both hourly and daily scales. Vulture movements in 10 migration events were recorded with satellite-reporting GPS sensors, and flight behavior was observed visually, aided by on-the-ground VHF radio-tracking. We used the North American Regional Reanalysis dataset to obtain values for wind speed, turbulent kinetic energy (TKE), and cloud height and used a digital elevation model for a measure of terrain ruggedness. A turkey vulture fitted with a heart-rate logger during 124 h of flight during 38 contiguous days showed only a small increase in mean heart rate as distance traveled per day increased, which suggests that, unlike flapping, soaring flight does not lead to greatly increased metabolic costs. Data from 10 migrations for 724 hourly segments and 152 daily segments showed that vultures depended heavily upon high levels of TKE in the atmospheric boundary layer to increase flight distances and maintain preferred bearings at both hourly and daily scales. We suggest how the MEM can be extended to other spatial and temporal scales of avian migration. Our success in relating model-derived atmospheric variables to migration indicates the potential of using regional reanalysis data, as here, and potentially other regional, higher-resolution, atmospheric models in predicting changing movement patterns of soaring birds under various scenarios of climate and land use change.

    Deltas contain sedimentary records that are not only indicative of water-level changes, but also particularly sensitive to earthquake shaking typically resulting in soft-sediment-deformation structures. The Kürk lacustrine delta lies at the south-western extremity of Lake Hazar in eastern Turkey and is adjacent to the seismogenic East Anatolian Fault, which has generated earthquakes of magnitude 7. This study re-evaluates water-level changes and earthquake shaking that have affected the Kürk Delta, combining geophysical data (seismic-reflection profiles and side-scan sonar), remote sensing images, historical data, onland outcrops and offshore coring. The history of water-level changes provides a temporal framework for the depositional record. In addition to the common soft-sediment deformation documented previously, onland outcrops reveal a record of deformation (fracturing, tilt and clastic dykes) linked to large earthquake-induced liquefactions and lateral spreading. The recurrent liquefaction structures can be used to obtain a palaeoseismological record. Five event horizons were identified that could be linked to historical earthquakes occurring in the last 1000 years along the East Anatolian Fault. Sedimentary cores sampling the most recent subaqueous sedimentation revealed the occurrence of another type of earthquake indicator. Based on radionuclide dating (Cs and Pb), two major sedimentary events were attributed to the ad 1874 to 1875 East Anatolian Fault earthquake sequence. Their sedimentological characteristics were determined by X-ray imagery, X-ray diffraction, loss-on-ignition, grain-size distribution and geophysical measurements. The events are interpreted to be hyperpycnal deposits linked to post-seismic sediment reworking of earthquake-triggered landslides.

    Duzgun, B.; Komurgoz, G.

    2014-01-01

    The last decade has seen an increase in the importance of energy efficiency and the sustainable use of energy resources due to their significant benefits for reducing a country's dependence on foreign energy resources and increasing awareness on environmental problems. Turkey aims to reduce its energy intensity by 20% up to 2023, and in order to accomplish this target, the country plans to use energy more effectively in various industries and develop financial mechanisms for energy efficiency. Although much effort has been made to improve energy efficiency, additional policies such as marked-based incentives are still necessary. This article deals with one of the many market-based energy efficiency policies, called Tradable White Certificates (WhC) or Energy Efficiency Obligations. The current situation of the energy field in Turkey and energy consumption by industries is presented first in this paper, followed by potentials for energy efficiency in each industry and energy efficiency policies. Furthermore, the theory and applicability of a WhC System is introduced and discussed in terms of market conditions, choice of obligated participants and market mechanisms and barriers for the Turkish electricity and natural gas market to benefit from the residential and industrial energy savings potential. - Highlights: • Energy efficiency is the most effective way to reduce foreign energy dependency. • Turkey aims reducing at least 20% of energy intensity in the year 2023. • Energy consumption of industry is 35% of total energy consumption in Turkey. • Marked based policy elements create new opportunities in environmental markets. • WhC System can be implemented in PMUM under the control of regulatory authority

    2011-12-01

    Turkey is positioned on the boundary between the Eurasian and African/Arabian plates, providing an ideal natural laboratory for learning passive and active earth processes such as deformation, metamorphism, earthquakes and volcanism. Central Turkey historically has played an important role in evolution of the Alpine orogeny. The Kirsehir Complex is one of three Mesozoic-Early Tertiary metamorphic and plutonic mid-crustal basement units exposed in central Turkey. The most common lithology of the metamorphites are the banded gneisses, which are intercalated with layers of schists, amphibolites and quartzite, and marbles representing the structurally the highest metamorphites of the study area. The metamorphites are characterized by multiple folding episodes and overprinting faults (thrust, normal and strike-slip). These metamorphites reached peak metamorphic conditions of upper amphibolite facies, as indicated by local presence of clinopyroxene, sillimanite, hornblende, andalusite and garnet. Later, retrograde greenschist facies conditions were attained characterized by the alteration of feldspar and mafic minerals to muscovite and chlorite/actinolite, respectively. The microstructures of selected minerals can be used to bracket the metamorphic grade during which microstructure formed. Quartz displays undulose extinction, deformation bands, subgrains and deformation lamellae, and recrystallisation. The presence of lobate grain boundaries of quartz indicates that GBM recrystallisation occurred. Undulose extinction and recrystallisation are common in micas. Recrystallisation, core-mantle structures in feldspar, myrmekites in K-feldspars within the gneisses suggest that deformation occurred within the amphibolite facies. Garnet occurs as slightly elliptical porphroclats. Sillimanite is present as fibrolite growing near biotite and microboudinaged. Andalusite porphyroblast/porphroclats are elongate and microboudinaged. Kinematic indicators (asymmetric mantled grains, S

    2017-08-15

    Turkey is a key country in order to realize the Southern Gas Corridor (SGC) due to its geographical location. However, as the main transit country within the SGC, Turkey could potentially exert market power with gas transits. Whether Turkey exerts market power or not, is crucial for an economic assessment of the SGC. Hence, the article investigates this issue quantitatively using a global partial equilibrium gas market model. An oligopolistic and a competitive supply structure in Europe in 2030 are considered in the model. If the European gas market in 2030 is characterized by an oligopolistic supply, Turkey is able to exert market power resulting in higher prices compared to competitive transits, in particular in South Eastern Europe. In a competitive market structure, however, the importance of the SGC and thus the potential of Turkish transit market power is limited.

    2010-01-01

    Turkey's demand for energy and electricity is increasing rapidly and heavily dependent on expensive imported energy resources that place a big burden on the economy and air pollution is becoming a great environmental concern in the country. As would be expected, the rapid expansion of energy production and consumption has brought with it a wide range of environmental issues at the local, regional and global levels. With respect to global environmental issues, Turkey's carbon dioxide (CO 2 ) emissions have grown along with its energy-consumption. States have played a leading role in protecting the environment by reducing emissions of greenhouse gases (GHGs). In this regard, renewable energy resources appear to be the one of the most efficient and effective solutions for clean and sustainable energy development in Turkey. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources.

    Full Text Available Along with a growing elderly population in the world and in our country, elder abuse and neglect has been a major problem. The purpose of this study is to identify and systematically review the studies investigating elder abuse and neglect in Turkey. Evaluation of the studies on elder abuse and neglect in Turkey showed that the elderly are often abused by family members and they are often exposed to emotional, physical, economic and psychological abuse. All of the studies reviewed in this paper were descriptive cross-sectional studies investigating elder abuse and neglect. The studies reviewed presented significant results revealing the prevalence of elder abuse and neglect in Turkey. In conclusion, this systematic review revealed that research on this issue in Turkey is insufficient and there is a need for studies conducted with larger samples covering an entire city.

    2015-04-01

    Full Text Available Laz (South Caucasian language, which is spoken primarily on the southeastern coast of the Black Sea in Turkey, is being threatened by language endangerment. Having no official status, Laz language is considered to be an ethnic minority language in Turkey. All Laz people residing in Turkey are bilingual with the official language in the country, Turkish, and use Laz most frequently in intrafamilial conversations. In this article, Laz language is removed from the dusty pages of Turkish history as a response to the threat of language attrition in the world. Accordingly, language endangerment is viewed in terms of a sociolinguistic phenomenon within the boundaries of both language-internal and -external factors. Laz language revitalization acts have also been scrutinized. Having a dekko at the history of modern Turkey will enlighten whether those revitalization acts and/or movements can offer a novus ortus (new birth for the current situation of Laz language.

    Full Text Available Turkey has witnessed high fertility rates and low mortality rates until 2000s. Young population structure, need for infrastructure for growing population and reproductive health issues were always on the agenda of policy makers throughout the history of Turkey. After the decline in total fertility rate below replacement level, vibrant discussions and search for a new policy framework began to be visible in the recent years. After the establishment of new Republic in Turkey in 1923 pronatalist policies were active until the beginning 1960s. After the First Development Plan in 1962, policy shift was towards an antinatalist direction until 2000. After a short period between 2000 and 2012 which can not be put any category in terms of fertility policy government clearly declared its position favouring pronatalist policies and mobilised bureaucracy for developing new policy options. This paper summarizes the fertility policies and demographic transition of Turkey and evaluates possible policy options

    Seven major carbonate microfacies are defined in the Devonian - Carboniferous (D/C) strata (50 m) of the Anseremme railway bridge section, south of Dinant. They permit recognition of several levels encompassing the Etroeungt and Hastie??re formations. "Bathymetric" sequences range from open marine, below the storm wave base, to semi-restricted lagoon. This sequence records a shallowing-upward trend of the relative sea level, from environments below the storm wave base to strongly eroded supraticial pre-evaporitic environments. Faunal components (echinoderms, brachiopods...) indicate open-marine domain for the first six microfacies located within the dysphoticeuphotic zone in relatively shallow waters. The textures of the rocks (mudstones to rudstones) associated with lamination characteristics indicate the position of the storm (SWB) and the fair-weather (FWWB) wave bases. Microfacies seven suggests a semi-restricted platform with salinity fluctuations from hypersaline brines to brackish waters. Thus, the boundary of the Etroeungt/Hastie??re formations is marked by an abrupt drop in sea level. Carbonate micro-conglomerates recording an important erosive phase and a sedimentary hiatus. The environment is again open marine in the upper part of the Hastie??re Formation. Our conclusion is that the Anseremme section is not a reliable continuous succession for the study of the D/C boundary. This confirms the VAN STEENWINKEL (1988, 1993 hypothesis based on other arguments. Conodont faunas demonstrate that the Devonian sequence spans the five youngest conodont zones, but that two of these zones are not represented. The Epinette Formation is dated as the youngest part of the Middle expansa Zone. Thus, the boundary with the Late praesulcata Zone probably coincides with the sharp sedimentological change at the base of the Etroeungt Formation, which is interpreted to belong entirely to this zone. The disconformably overlying basal bed 159 of the Hastie??re Formation is dated

    The aim of this prospective, referral-based study was to assess demographical and developmental features associated with childhood masturbation in Turkey. A total of 61 children with childhood masturbation who were referred for the first time to the Department of Child Psychiatry were examined from demographical, psychosocial and medical aspects and compared with two control groups consisting of 61 age and gender matched children who were brought to the paediatric outpatient clinics and 43 children and adolescents who were the biological siblings of the study group. In children with masturbation, sleep difficulties were more frequent (P masturbation was often associated with a genito-urinary disorder or a stressful life event like weaning, the birth of a sibling, or separation from the parents. This is the first controlled study investigating the clinical and the developmental features of childhood masturbation. These findings may help identify children who could be at risk for this condition.

    Survey research was conducted with the aim of better understanding nurses' perceptions of organizational factors which relate to their job satisfaction and motivation in Turkey. Nurses (N = 290) who were employed at a training and research hospital, part of the Turkish Republic Ministry of Health, were included. The questionnaire used was developed for this study based on Hackman and Oldman's job enrichment theory. The results showed that only one third of the nurse leaders and one in five of the staff nurses reported being satisfied with their job. The participants saw the five core job dimensions of Hackman and Oldman's work design model: skill variety, task identity, task significance, autonomy, and feedback as important for nurses. Nursing was described by the participants as hard and challenging, but they also found it meaningful and said that it gave them the opportunity to use their skills and abilities.

    The aim of this study was to explore how the future of technological developments in hydrogen will be shaped in Turkey by using a two-round Delphi method undertaken to determine and measure the expectations of the sector representatives through online surveys where a total of 60 experts responded from 18 different locations. The article discusses not only the expert sights on hydrogen technologies but also all bibliometrical approaches. The results showed that the hydrogen economy will enhance innovations as well as economic prosperities with the support of appropriate policies. Formulating such policies requires a timely and detailed understanding of the latest R and D trends and developments in science and technology policy in all developed countries, and the comprehensive analysis of these developments to enable accurate predictions of future science and technology trends. Therefore, we hope that this study can shed a light on the future use of hydrogen technologies, especially for policy makers. (author)

    2015-09-01

    Full Text Available Obesity is a major public health problem affecting an important proportion of the Turkish population. The prevalence of obesity has significantly increased among adult Turkish population over the past 20 years. In 1990, 18.8% of the adult population was obese (28.5% among women and 9% among men, and the prevalence increased to 36% in 2010 (44% among women and 27% among men. From the data, we found that the prevalence of obesity in Turkey has increased steadily from 1990 to 2010 in both genders. Adult obesity-associated risk factors are age, gender, hypertension, hyperlipidemia, smoking cessation, alcohol consumption, high household income, low education level and physical activity, occupation, marital status and a family of selected medical conditions (e.g. obesity, diabetes and hypertension. To control obesity, necessary precautions should urgently be taken. The precautions include serious public health education encouraging a well-balanced diet and increasing physical activity.

    Today, many studies are conducted in order to determine bullying behaviors and to resolve conflicts with the purpose of increasing and maintaining organizational success in developed countries. According to these studies, bullying cases are more common in public institutions when compared to other sectors. In public institutions, bullying generally occurs when successful workers are discouraged and/or harassed by their managers, thus leaving them feeling distressed and dissatisfied with their jobs. The present study examines whether forest engineers working in the seven geographical regions of Turkey are exposed to bullying behaviors, the level of any bullying, and whether there are any regional differences (N = 835). Through statistical analysis, a significant relationship was determined between bullying and demographic characteristics. The results of the present study were evaluated along with the results of other studies, and some suggestions were made in order to prevent bullying behaviors in forestry organizations.

  4. Aspects of the sedimentology of some uranium-bearing sandstones in the Beaufort West area, Cape Province

    Cole, D.I.

    1980-01-01

    The sedimentology of some uranium-bearing sandstones from the Beaufort Group in the Beaufort West area was studied by use of some 116 vertical profiles measured across and adjacent to 14 mineralized deposits. The vertical profiles consist of 91 field sections and 25 borehole logs. The sandstones are usually multistorey and alternate with a mudstone and/or siltstone succession. The vertical profiles basically consist of a succession of facies. Some 19 facies were recognised within the sandstones on the basis of texture and sedimentary structure. The facies transitions within the sandstone sequence were subjected to a one-step Markov chain analysis. The cumulative thickness of uranium mineralization for each sedimentary facies within the sandstone sequence was measured. Some 99 per cent of the total cumulative thickness occurs within the coarser-grained facies (grain sizes in excess of very fine), which suggests that permeability was an important control on the mineralization. The coarser-grained facies, which mostly represent lower point bar or channel bar deposits near the base of each storey, probably acted as suitable aquifers for the transport of uraniferous solutions. Irregularities in the base of each storey may have interrupted the flow of these solutions and allowed sufficient time for precipitation of the uranium. Carbonaceous debris is frequently associated with the mineralized deposits and most likely acted as an indirect reductant for this precipitation. Mineralization decreases upwards in the sandstone sequence and some 40 per cent of the total cumulative thickness is restricted to the initial storey. The horizontally bedded facies contain a high proportion of the total cumulative thickness of mineralization (45 per cent) and this again may be related to a more abundant content of carbonaceous debris

    Modern travertines, carbonate deposits in Ca-rich hydrothermal water with high pCO2, often display a changing environment along the water path, with corresponding variability in the microbial communities. We investigated a travertine-bearing hot spring at the Blue Pool in northern Sumatra, Indonesia. The thermal water of 62 °C with high H2S (200 μM) and pCO2 ( 1 atm) developed a travertine mound 70 m wide. The concentrations of the gas components H2S and CO2, decrease immediately after the water is discharged, while the dissolved oxygen, pH, and aragonite saturation increase in the downstream direction. Responding to the geochemical gradient in the water, the surface biofilms change color from white to pink, light-green, dark-green, and brown as the water flows from the vent; this corresponds to microbial communities characterized by chemolithoautotrophs (Halothiobacillaceae), purple sulfur bacteria (Chromatiaceae), Anaerolineaceae, and co-occurrence of green non-sulfur bacteria (Chloroflexales)-Cyanobacteria, and green sulfur bacteria (Chlorobiales), respectively. In an environment with a certain level of H2S (> 1 μM), sulfur digestion and anoxygenic photosynthesis can be more profitable than oxygenic photosynthesis by Cyanobacteria. The precipitated carbonate mineral consists of aragonite and calcite, with the proportion of aragonite increasing downstream due to the larger Mg2 +/Ca2 + ratio in the water or the development of thicker biofilm. Where the biofilm is well developed, the aragonite travertines often exhibit laminated structures that were likely associated with the daily metabolism of these bacteria. The microbiological and sedimentological features at the Blue Pool may be the modern analogs of geomicrobiological products in the early Earth. Biofilm of anoxygenic photosynthetic bacteria had the potential to form ancient stromatolites that existed before the appearance of cyanobacteria.

  6. CORE-BASED INTEGRATED SEDIMENTOLOGIC, STRATIGRAPHIC, AND GEOCHEMICAL ANALYSIS OF THE OIL SHALE BEARING GREEN RIVER FORMATION, UINTA BASIN, UTAH

    An integrated detailed sedimentologic, stratigraphic, and geochemical study of Utah's Green River Formation has found that Lake Uinta evolved in three phases (1) a freshwater rising lake phase below the Mahogany zone, (2) an anoxic deep lake phase above the base of the Mahogany zone and (3) a hypersaline lake phase within the middle and upper R-8. This long term lake evolution was driven by tectonic basin development and the balance of sediment and water fill with the neighboring basins, as postulated by models developed from the Greater Green River Basin by Carroll and Bohacs (1999). Early Eocene abrupt global-warming events may have had significant control on deposition through the amount of sediment production and deposition rates, such that lean zones below the Mahogany zone record hyperthermal events and rich zones record periods between hyperthermals. This type of climatic control on short-term and long-term lake evolution and deposition has been previously overlooked. This geologic history contains key points relevant to oil shale development and engineering design including: (1) Stratigraphic changes in oil shale quality and composition are systematic and can be related to spatial and temporal changes in the depositional environment and basin dynamics. (2) The inorganic mineral matrix of oil shale units changes significantly from clay mineral/dolomite dominated to calcite above the base of the Mahogany zone. This variation may result in significant differences in pyrolysis products and geomechanical properties relevant to development and should be incorporated into engineering experiments. (3) This study includes a region in the Uinta Basin that would be highly prospective for application of in-situ production techniques. Stratigraphic targets for in-situ recovery techniques should extend above and below the Mahogany zone and include the upper R-6 and lower R-8.

    The Permian to Triassic Khuff carbonate reservoirs (and equivalents) in the Middle East are estimated to contain about 38.4% of the world's natural gas reserves. Excellent exposed outcrops in central Saudi Arabia provide good outcrop equivalents to subsurface Khuff reservoirs. This study conduct high resolution outcrop scale investigations on an analog reservoir for upper Khartam of Khuff Formation. The main objective is to reconstruct litho- and chemo- stratigraphic outcrop analog model that may serve to characterize reservoir high resolution (interwell) heterogeneity, continuity and architecture. Given the fact of the limitation of subsurface data and toolsin capturing interwell reservoir heterogeneity, which in turn increases the value of this study.The methods applied integrate sedimentological, stratigraphic petrographic, petrophysical data and chemical analyses for major, trace and rare earth elements. In addition, laser scanning survey (LIDAR) was also utilized in this study. The results of the stratigraphic investigations revealed that the lithofacies range from mudstone, wackestone, packestone and grainstone. These lithofacies represent environments ranging from supratidal, intertidal, subtidal and shoal complex. Several meter-scale and less high resolution sequences and composite sequences within 4th and 5th order cycles were also recognized in the outcrop analog. The lithofacies and architectural analysis revealed several vertically and laterally stacked sequences at the outcrop as revealed from the stratigraphic sections and the lidar scan. Chemostratigraphy is effective in identifying lithofacies and sequences within the outcrop analog. Moreover, different chemical signatures were also recognized and allowed establishing and correlating high resolution lithofacies, reservoir zones, layers and surfaces bounding reservoirs and non-reservoir zones at scale of meters or less. The results of this high resolution outcrop analog study might help to understand

    The origin of breccias in the Neoproterozoic Katanga Supergroup in D.R of Congo is still a matter of debate. At the Shangoluwe Cu deposit located in the Kambove mining district (central part of the Lufilian arc), the sedimentary breccias bearing Cu mineralisation have been investigated for lithological and sedimentological study, quantitative analysis of the breccias fragments and fault kinematic analysis in order to understand the origin of the breccias, their lithostratigraphic position and the timing of mineralisation. At Shangoluwe, three sedimentary breccias sequentially deposited within the Kundelungu rocks can be identified on the basis of the nature of the matrix and fragments; from bottom to the top, the Ferruginous Breccias, the Dolomitic Breccias and the Siliceous Breccias. These breccias were deposited as lenses. The presence of debris and grain flows, a finely laminated matrix, pseudo-stratification, normal and reverse graded-bedding, and the presence of interbedded siltstone, sandy shale, dolomitic shale, shale and dolomite, are considered as evidence of a sedimentary origin of the breccias. The log normal distribution of the fragments indicates that gravity flow was the main deposition mechanism. The Ferruginous and Dolomitic Breccias are regarded as contemporaneous with the Kundelungu Group. They were deposited as lenses interbedded in the Kanianga and Mongwe formations, both affected by the Lufilian orogeny (D1 - Kolwezian and D2 - Monwezian phases). The Siliceous Breccias are post-orogenic as shown by the presence of an erosional and angular unconformity respectively on the Dolomitic Breccias and the Kundelungu formations. Therefore, the Siliceous Breccias are attributed to the Lower Palaeozoic Biano Subgroup and the lithostratigraphy of the Biano Subgroup is proposed for revision accordingly. Copper mineralisation post-dates the deposition of the breccias, the dissolution of dolomite fragments and in-situ fragmentation. This mineralisation

  9. Sedimentology, eruptive mechanism and facies architecture of basaltic scoria cones from the Auckland Volcanic Field (New Zealand)

    Scoria cones are a common type of basaltic to andesitic small-volume volcanoes (e.g. 10- 1-10- 5 km3) that results from gas-bubble driven explosive eruptive styles. Although they are small in volume, they can produce complex eruptions, involving multiple eruptive styles. Eight scoria cones from the Quaternary Auckland Volcanic Field in New Zealand were selected to define the eruptive style variability from their volcanic facies architecture. The reconstruction of their eruptive and pyroclastic transport mechanisms was established on the basis of study of their volcanic sedimentology, stratigraphy, and measurement of their pyroclast density, porosity, Scanning Electron Microscopy, 2D particle morphology analysis and Visible and Near Visible Infrared Spectroscopy. Collection of these data allowed defining three end-member types of scoria cones inferred to be constructed from lava-fountaining, transitional fountaining and Strombolian type, and explosive Strombolian type. Using the physical and field-based characteristics of scoriaceous samples a simple generalised facies model of basaltic scoria cones for the AVF is developed that can be extended to other scoria cones elsewhere. The typical AVF scoria cone has an initial phreatomagmatic phases that might reduce the volume of magma available for subsequent scoria cone forming eruptions. This inferred to have the main reason to have decreased cone volumes recognised from Auckland in comparison to other volcanic fields evolved dominantly in dry eruptive condition (e.g. no external water influence). It suggests that such subtle eruptive style variations through a scoria cone evolution need to be integrated into the hazard assessment of a potentially active volcanic field such as that in Auckland.

  10. Sedimentology and preservation of aeolian sediments on steep terrains: Incipient sand ramps on the Atacama coast (northern Chile)

    2017-05-01

    The origin of topographically controlled aeolian landforms in high-relief settings is difficult to synthesize under general models, given the dependence of such accumulations on local morphology. Quaternary sand ramps have been linked to palaeoclimate, regional geomorphology and wind patterns; however, controls on the early development and preservation of such landforms are poorly known. This study describes the morphology and sedimentology of complex sedimentary aprons along steep coastal slopes in the Atacama Desert (Chile). Direct slope accessibility and continuous stratigraphic exposures enable comparisons between active processes and stratigraphic signatures. Stratigraphic facies distribution and its links with patterns of aeolian deposition show that the preservation of wind-laid sediments depends on the morphology and processes of specific slope sectors. The spatial organization of runoff depends on bedrock configuration and directly controls the permanence or erosion of aeolian sediment. The occurrence of either water or mass flows depends on the role of aeolian fines in the rheology of flash floods. In turn, the establishment of a rugged surface topography controlled by patterns of mass-flow deposition creates local accommodation for aeolian fines, sustaining the initial aggradation of a colluvial-aeolian system. By contrast, slopes subject to runoff develop a thin, extensive aeolian mantle whose featureless surface is subject mostly to sediment bypass down- and across-slope; the corresponding stratigraphic record comprises almost exclusively thin debris-flow and sheetflood deposits. Slope morphology and processes are fundamental in promoting or inhibiting aeolian aggradation in mountain settings. Long-term sand-ramp construction depends on climate and regional topography, but the initial development is probably controlled by local geomorphic factors. The observed interactions between wind and topography in the study area may also represent a process

  11. Missoula flood dynamics and magnitudes inferred from sedimentology of slack-water deposits on the Columbia Plateau, Washington

    Smith, G.A.

    1993-01-01

    Sedimentological study of late Wisconsin, Missoula-flood slack-water sediments deposited along the Columbia and Tucannon Rivers in southern Washington reveals important aspects of flood dynamics. Most flood facies were deposited by energetic flood surges (velocities>6 m/sec) entering protected areas along the flood tract, or flowing up and then directly out of tributary valleys. True still-water facies are less voluminous and restricted to elevations below 230 m. High flood stages attended the initial arrival of the flood wave and were not associated with subsequent hydraulic ponding upslope from channel constrictions. Among 186 flood beds studied in 12 sections, 57% have bioturbated tops, and about half of these bioturbated beds are separated from overlying flood beds by nonflood sediments. A single graded flood bed was deposited at most sites during most floods. Sequences in which 2-9 graded beds were deposited during a single flood are restricted to low elevations. These sequences imply complex, multi-peaked hydrographs in which the first flood surge was generally the largest, and subsequent surges were attenuated by water already present in slack-water areas. Slack-water - sediment stratigraphy suggests a wide range of flood discharges and volumes. Of >40 documented late Wisconsin floods that inundated the Pasco Basin, only about 20 crossed the Palouse-Snake divide. Floods younger than the set-S tephras from Mount St.Helens were generally smaller than earlier floods of late Wisconsin age, although most still crossed the Palouse-Snake divide. These late floods primarily traversed the Cheney-Palouse scabland because stratigraphy of slack-water sediment along the Columbia River implies that the largest flood volumes did not enter the Pasco Basin by way of the Columbia River. 47 refs., 17 figs., 2 tabs

    The effect of tropical and extratropical cyclones on coastal wetlands and marshes is highly variable and depends on a number of climatic, geologic, and physical variables. The impacts of storms can be either positive or negative with respect to the wetland and marsh ecosystems. Small to moderate amounts of inorganic sediment added to the marsh surface during storms or other events help to abate pressure from sea-level rise. However, if the volume of sediment is large and the resulting deposits are thick, the organic substrate may compact causing submergence and a loss in elevation. Similarly, thick deposits of coarse inorganic sediment may also alter the hydrology of the site and impede vegetative processes. Alternative impacts associated with storms include shoreline erosion at the marsh edge as well as potential emergence. Evaluating the outcome of these various responses and potential long-term implications is possible from a systematic assessment of both historical and recent event deposits. A study was conducted by the U.S. Geological Survey to assess the sedimentological and radiochemical characteristics of marsh deposits from Assateague Island and areas around Chincoteague Bay, Maryland and Virginia, following Hurricane Sandy in 2012. The objectives of this study were to (1) characterize the surficial sediment of the relict to recent washover fans and back-barrier marshes in the study area, and (2) characterize the sediment of six marsh cores from the back-barrier marshes and a single marsh island core near the mainland. These geologic data will be integrated with other remote sensing data collected along Assateague Island in Maryland and Virginia and assimilated into an assessment of coastal wetland response to storms.

    Full Text Available ODP Site 1202 of Leg 195 was designed primarily for a high-resolution study of the paleoceanography of the Kuroshio Current in the southern Okinawa Trough off NE Taiwan. Four holes were drilled in which Hole 1202D is described in detail in this study for an assessment of core quality for paleoceanography study and understanding of sedimentological features, especially turbidite sedimentation and the sediment provenances during the Late Quaternary in the southern Okinawa Trough. Pelagic mud with insignificant silt or sand layers is observed from the core top down to 133 m (mbsf; Marine Isotope Stages 1-3, but the silt-sand layer ratio (SLR: total thickness of silt and sand layers / 1.5 m of core increases gradually from a value of 50 % between 223 and 279 m, followed by decreases to values 250 _ Slate fragments are commonly found in fine-grained turbidite dominant intervals (160 - 280 m, while mica flakes can be observed in the muds throughout the core. The major detrital components were derived primarily from the Miocene slate belt of the pre-collision accretionary prism of the Central Range in northern Taiwan. The occurrence of volcanics could represent submarine volcanic activity in the active-opening Okinawa Trough back-arc basin off NE Taiwan. Shallow-marine fossils including benthic foraminifers, echinoids, bryozoans and mollusks are also found in the fine-grained turbidite dominant intervals. These fossil assemblages could have been deposited in the shallow shelf and then transported to the depositional site along with voluminous terrigenous materials derived from Taiwan, via submarine channels or by slope failures due to frequent earthquakes induced by plate convergence/collision and extension in the southwestern Okinawa Trough off NE Taiwan. It is concluded that the top 133 m of the core is better suited for paleoceanographic reconstruction.

  1. Energy policies of IEA countries: Turkey 1997 review

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    1997-12-31

    This IEA report provides a comprehensive in-depth assessment of the energy policies of Turkey, including recommendations on future policy developments. The report highlights the rapid increase in Turkey`s energy consumption and the large investments needed to meet the demand growth. Turkey has sought to attract private inward investment in the energy sector, in particular in electricity, through build-own-operate and build-operate-transfer schemes and transfers of operating rights. Turkey needs to set up a stable legal framework to continue this policy. It needs to push forward with market reforms, as well as to create a level playing field for competition, with energy prices reflecting the true costs of various fuels. Natural gas consumption is also expected to continue to increase.

    Astroviruses are a leading cause of gastroenteritis in mammals and birds worldwide. Although historically thought to be species-specific, increasing evidence suggests that astroviruses may cross species barriers. In this report, we used enzyme-linked immunosorbent assays to screen sera from three distinct human cohorts involved in influenza studies in Memphis, TN or Chapel Hill, NC, and Midwestern poultry abattoir workers for antibodies to turkey astrovirus type 2 (TAstV-2). Surprisingly, 26% of one cohort's population was TAstV-2 positive as compared to 0 and 8.9% in the other cohorts. This cohort was composed of people with exposure to turkeys in the Midwestern United States including abattoir workers, turkey growers, and non-occupationally exposed participants. The odds of testing positive for antibodies against turkey astrovirus among abattoir workers were approximately 3 times higher than the other groups. These studies suggest that people with contact to turkeys can develop serological responses to turkey astrovirus. Further work is needed to determine if these exposures result in virus replication and/or clinical disease.

    The aim of the present paper is to describe the development of the National Plan of Action for Food and Nutrition (NPAFN) for Turkey. Access to a safe and healthy variety of food, a fundamental human right, was stressed by the International Conference on Nutrition and by the World Food Summit. In the International Conference on Nutrition in December 1992, one major commitment was the preparation of NPAFN. The NPAFN for Turkey was designed according to this commitment. Turkey. To this end, under the coordination of the State Planning Organization, a Working Committee Report for National Food and Nutrition Strategy of Turkey was prepared and published, with the participation of different sectors. The goal of the prepared National Food and Nutrition Strategy for Turkey is to protect and promote health through and healthy nutrition and reduce the burden of diseases, while contributing to socio-economic development and a sustainable food security. In Turkey the NPAFN was developed and implementation has initiated. Nearly for all the actions, related projects are being developed.

  5. The Eastern Partnership and the EU-Turkey Energy Relations

    Full Text Available This article discusses the prospects and challenges of energy cooperation between the European Union (EU and Turkey within the context of the Eastern Partnership (EaP. Part of the EaP agenda is to advance energy cooperation between the EU and the partner states, particularly regarding the diversification of import routes. As an energy corridor between the EU and the hydrocarbon-rich Caspian states, Turkey is a strategic asset for European energy security. Turkey also has economic ties and political capital in the Caspian region that can help the EU reach out to its eastern partners. Despite robust incentives for cooperation, however, the EU-Turkey energy partnership has so far failed to meet mutual expectations. This article argues that this is primarily due to the inability of the two actors to credibly commit to regional energy cooperation. Commitment problem stems from two factors. First, the predominance of national energy interests over communal ones undermines credible commitment. The variation in energy needs of Member States prevents the EU from acting in unison in external energy policy. Similarly, Turkey also prioritizes its own energy security, particularly in its relations with suppliers, which undermines cooperation with the EU. Second, the EU and Turkey hold divergent perspectives on the potential political payoffs of energy cooperation. Turkish decision makers are convinced that energy cooperation warrants palpable progress in Turkey’s accession while most EU actors appear hesitant to establish a direct connection between energy and accession.

    Many factors to be appropriately addressed in moving towards energy sustainability in Turkey are examined. These include harnessing sustainable energy sources, utilizing sustainable energy carriers, increasing efficiency, reducing environmental impact and improving socioeconomic acceptability. The latter factor includes community involvement and social acceptability, economic affordability and equity, lifestyles, land use and aesthetics. On the other hand, Turkey, with its young population and growing energy demand per person, its fast growing urbanization, and its economic development, has been one of the fast growing power markets of the world for the last two decades. Turkey is heavily dependent on expensive imported energy resources that place a big burden on the economy and air pollution is becoming a great environmental concern in the country. In this regard, renewable energy resources appear to be the one of the most efficient and effective solutions for clean and sustainable energy development in Turkey. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources.

    This paper discusses Turkey's attitudes vis-a-vis nuclear weapons and Ballistic Missile Defense in the light of recent developments in the Iranian nuclear program and NATO's evolving concept of extended deterrence. On the one hand, the long-standing forward deployment of US tactical nuclear weapons in Turkey and the country's role in the US Phased Adaptive Approach BMD architecture are still considered to be key elements of national security. On the other, security guarantees offered to Turkey by NATO and the US appear less and less credible in the face of rising regional threats. As this paper shows, there is a growing gap between official policy and public perceptions inside Turkey vis-a-vis the US, Iran, and nuclear weapons, as well as a growing Turkish aspiration to autonomy in its security and defense policy. While one should not expect Turkey to develop nuclear weapons anytime soon, an unchecked Iranian regional power could bring Ankara to hedge its bets in the long term. Turkey's controversial recent decision to buy a Chinese system for its national air and missile defense rather than European or US equipment should be seen in the light of this search for autonomy.

    2008-01-01

    This paper deals with Turkey's hydropower potential and its long-term electric energy demand predictions. In the paper, at first, Turkey's energy sources are briefly reviewed. Then, hydropower potential is analyzed and it has been concluded that Turkey's annual economically feasible hydropower potential is about 188 TWh, nearly 47% greater than the previous estimation figures of 128 TWh. A review on previous prediction models for Turkey's long-term electric energy demand is presented. In order to predict the future demand, new increment ratio scenarios, which depend on both observed data and future predictions of population, energy consumption per capita and total energy consumption, are developed. The results of 11 prediction models are compared and analyzed. It is concluded that Turkey's annual electric energy demand predictions in 2010, 2015 and 2020 vary between 222 and 242 (average 233) TWh; 302 and 356 (average 334) TWh; and 440 and 514 (average 476) TWh, respectively. A discussion on the role of hydropower in meeting long-term demand is also included in the paper and it has been predicted that hydropower can meet 25-35% of Turkey's electric energy demand in 2020

    Avian metapneumovirus (aMPV) causes diseases like rhinotracheitis in turkeys, swollen head syndrome in chickens and avian rhinotracheitis in other birds. Causing respiratory problems, aMPV adversely affects production and inflicts immense economic losses and mortalities, especially in turkey flocks. In recent years, several serological and molecular studies have been conducted on this virus, especially in poultry in Asia and Iran. The purpose of the present study was detecting and subtyping aMPV by reverse transcriptase polymerase chain reaction (RT-PCR) from non-vaccinated, commercial turkey flocks in Iran for the first time. Sixty three meat-type unvaccinated turkey flocks from several provinces of Iran were sampled in major turkey abattoirs. Samples were tested by RT-PCR for detecting and subtyping aMPV. The results showed that 26 samples from three flocks (4.10%) were positive for viral RNA and all of the viruses were found to be subtype B of aMPV. As a result, vaccination especially against subtype B of aMPV should be considered in turkey flocks in Iran to control aMPV infections.

    particles are dispersed, and the suspension is stabilized supported by our SEM observations. In alkaline water, kaolinite reveals a lower degree of consolidation. While, alkaline water has no measurable effect on illite and chlorite surface properties due to the absence of modifications in charge. Illite and chlorite form with other clasts clusters or aggregate structures in suspension when the particle interactions are dominated by attractive energies were formed. The aggregate structure plays a major part in the flow behavior of clay suspensions. Flocs will immobilize the suspending medium, and give rise to increasing viscosity and yield strength of the suspension. S. Hage, A. Hubert-Ferrari, L. Lamair, U. Avşar, M. El Ouahabi, M.

    2005-07-01

    This report provides a comprehensive in-depth assessment of the energy policies of Turkey including recommendations by the IEA on future policy developments. Recently, Turkey has taken steps to implement energy market reforms which have resulted in clear and significant benefits. Now, continued action is needed to see the process through to a successful conclusion. It is necessary to restructure the state-owned enterprises to operate in a competitive market, to create independent electricity and gas operators and to remove cross-subsidies from electricity and gas prices. Turkey has been very active in international co-operation in the energy sector. Some important oil and gas pipeline projects are underway or almost completed. This will improve the security of supply in Turkey and maintain its role as an important 'energy corridor' between East and West, while avoiding overuse of the Turkish Straits. Synchronisation of Turkey's electricity networks with the European UCTE grid is planned for 2006. Furthermore, the country already has transposed most EU energy laws and standards into national legislation. Turkey's general approach to energy policy has been highly supply-oriented. However, recent efforts have begun to focus more on energy efficiency and conservation. Nevertheless, stronger energy efficiency policies are needed, particularly in the transport sector. Turkey ratified the Framework Convention on Climate Change in February 2004 and is developing its climate change strategy. The government should strive to monitor the cost-effectiveness of its policies, consider defining an emissions target and ensure coordination among the various government bodies. Despite past progress, work remains to be done to achieve further reductions in air pollution. 28 figs., 23 tabs., 3 annexes

  14. Development of Electricity Generation from Renewable Energy Sources in Turkey

    2011-12-01

    Electricity is mainly produced from coal, natural gas and hydropower in Turkey. However, almost all the natural gas and high quality coal are imported. Thus, increasing the shares of both hydro and other renewables in energy supply is necessary to decrease dependency of the country on foreign sources. In 2008, the total installed capacity of Turkey was around 42000 MW and 66 % of this was from thermal sources. The remaining 33 % was from hydro, which leaves only one percent for the other renewable energy sources. The share of renewable energy in the energy budget of Turkey has increased in the last two decades; however, in 2008, only 17 % of the total electricity generation was realized from renewable sources most of which was hydro. According to State Hydraulic Works (SHW) which is the primary executive state agency responsible for the planning, operating and managing of Turkey's water resources, Turkey utilizes only around 35% of its economically viable hydro potential. The current situation clearly demonstrates the need for increasing the share of renewables in the energy budget. New laws, such as the Electricity Market Law, have been enacted and the following items were identified by the Ministry of Energy and Natural Resources of Turkey among primary energy policies and priorities: (i) decreasing dependency on foreign resources by prioritizing utilization of natural resources, (ii) increasing the share of renewable energy resources in the energy budget of Turkey; (iii) minimization of adverse environmental impacts of production and utilization of natural resources. The government's energy policy increased investments in renewable energy resources; however lack of a needed legal framework brought various environmental and social problems with this fast development. The development of the share of renewable resources in the energy budget, current government policy, and environmental concerns related with renewables, and ideas to improve the overall benefits of

    Full Text Available In this study, by handling private insurance sector in Turkey and the problems of the sector as a whole, the last stage that the insurance business in Turkey has reached has been evaluated. Basically, because of the fact that the most of the people had fatalistic understanding, religious leaders approached the concept of insurance negatively and adequate information hadn’t been gotten about insurance, the settlement of the idea of insurance in Turkey came true after 150 years later, at the end of 19. Century compared with Europe. As a result of changing conditions, Turkey is in 63rd in accordance with the insurance density on the world countries’ rank, and is in 39th rank in accordance with the primary production. In spite of this, when we examine the studies according to per person criteria, it is seen that the premium rate per person in Turkey is fortieth level among developed countries. The top reason of the fact that insurance business in Turkey hasn’t risen to the requested level is that there is still fatalistic society understanding; and also, the fact that insurance understanding hasn’t been settled, and hitching and late payment on damage payments of insurance firms, and not having an effective promotion and marketing understanding are seen as the primary reasons. Despite of these negative factors, in Turkey being an developing country, the insurance sector has a potential to show at least a threefold improvement from todays’ position in a short time in case of precautions to be taken by state and applying these precautions by seriousness.

    Full Text Available L’énergie en Turquie est aujourd’hui fournie par l’énergie fossile. De plus, la Turquie est dépendante de l’extérieur en matière d’énergie pour son économie et les secteurs divers qui en ont besoin. En Turquie, parallèlement aux informations ci-dessus, 83% de l’électricité de l’an 2008 provient des sources d’énergie fossile. Les perspectives d'avenir prévoient que la demande d’énergie de la Turquie augmentera et l’effet naturel de cette croissance sera l’augmentation du taux de dépendance énergétique à l'égard des autres pays. Les travaux effectués démontrent que, parmi les sources d’énergies renouvelables de la Turquie, le pouvoir hydraulique et le potentiel d’énergie éolienne sont les plus importants et que chacune de ces deux sources ont des potentiels techniques pour la production de l’électricité. La multiplication des centrales éoliennes au cours de ces dernières années est à relier à des facteurs comme la préparation de l’Atlas d’Energie Eolienne Turc, la disposition des lois afin d’aider les entrepreneurs du secteur privé et l’augmentation des prix du pétrole. Les centrales éoliennes fonctionneront dans la région de Marmara, la région d’Egée et dans la partie de méditerranée orientale de la Turquie où se manifestent plus souvent les vents violents. Il est probable que quelques autres centrales seront construites dans d'autres régions que celles citées précédemment.Covering its energy requirement from fossil energy sources for the most part, Turkey relies on outside sources to procure energy required for its economy and different sectors. Similarly, Turkey had produced 83 pct of the overall electricity in 2008 out of fossil energy sources. Future projectors indicate that the energy requirement of our country would augment and foreign-dependency in energy would thus increase accordingly.  The on-going studies state that especially hydraulic power and wind

    Tularemia is a zoonotic disease caused by Francisella tularensis. Sporadic tularemia cases have been increasingly reported particularly from provinces located at northwest and central regions of Turkey especially during last two decades, as well as waterborne outbreaks reported from almost all regions. Transmission most often occurs through consumption of contaminated water and food, thus, oropharyngeal form is the most common clinical presentation in our country. The aim of this study was to present a small outbreak experience in Afsin, country of Kahramanmaras province located at southern part of Turkey. A total of 10 patients (5 male, 5 female; age range 2-68 years; mean age 25 years) who were admitted to Afsin State Hospital with the complaints of swollen neck between 21 October 2013-22 January 2014, were evaluated considering their clinical findings and treatment outcomes. Following the diagnosis of the first tularemia case coming from Nadir village, a field investigation was performed. All villagers were informed about the disease and water samples from the possible sources of outbreak were collected by provincial health authorities. Lymph node aspirate and serum samples were sent for culture and serologic investigation and the environmental water samples were sent for molecular analysis to the National Tularemia Reference Laboratory at Public Health Institution of Turkey. Six out of 10 patients' sera were found positive in terms of F.tularensis antibodies between the titers of 1/320-1/1280 by microagglutination test (MAT) and diagnosis of oropharyngeal tularemia was based on the clinical and serological findings. One of the patients also presented with oculoglandular form accompanying oropharyngeal form. Cultures from aspirate samples that could be obtained from only two patients yielded negative results. Three out of six patients' lymph nodes were drained surgically and one was drained by ultrasound-guided needle. In one case lymph node suppuration occured

    The Las Chacritas Member is the lower part of the Cañadón Asfalto Formation (Jurassic). The unit is a completely continental limestone succession with volcanic contributions that were deposited during the development of the Cañadón Asfalto Rift Basin (Chubut province, Patagonia, Argentina). A detailed sedimentological analysis was performed in the Fossati depocenter to determine the paleoenvironments that developed in the context of this rift. The Las Chacritas Member represents a carbonate paleolake system with ramp-shaped margins associated with wetlands that were eventually affected by subaerial exposure and pedogenesis. This process is represented by three main subenvironments: a) a lacustrine setting sensu stricto (lacustrine limestone facies association), represented by Mudstones/Wackestones containing porifera spicules (F1), Intraclastic packstones (F6) and Tabular stromatolites (F10) in which deposition and diagenesis were entirely subaqueous; b) a palustrine setting (palustrine limestone facies association) containing Microbial Mudstones (F2), Intraclastic sandy packstone with ostracode remains (F3), Oncolitic packstone (F5), Brecciated limestone (F7) and Nodular-Mottled limestone (F8) representing shallow marginal areas affected by groundwater fluctuations and minor subaerial exposure; and c) a pedogenic paleoenvironment (pedogenic limestone facies association) including Intraclastic limestone (F4) and Packstones containing Microcodium (F9) facies displaying the major features of subaerial exposure, pedogenic diagenesis and the development of paleosols. The fluvial-palustrine-lacustrine succession shows a general shallow upward trend in which contraction-expansion cycles are represented (delimited by exposure and surface erosion). The variations in the successive formations reflect the responses to fluctuations in a combination of two major controls, the tectonic and local climatic variables. The predominance of the palustrine facies associations was

    Full Text Available The present study provides new knowledge about the so far largely unexplored Coral Patch seamount which is located in the NE Atlantic Ocean half-way between the Iberian Peninsula and Madeira. For the first time a detailed hydroacoustic mapping (MBES in conjunction with video surveys (ROV, camera sled were performed to describe the sedimentological and biological characteristics of this sub-elliptical ENE-WSW elongated seamount. Video observations were restricted to the southwestern summit area of Coral Patch seamount (water depth: 560–760 m and revealed that this part of the summit is dominated by exposed hard substrate, whereas soft sediment is just a minor substrate component. Although exposed hardgrounds are dominant for this summit area and, thus, offer suitable habitat for settlement by benthic organisms, the benthic megafauna shows rather scarce occurrence. In particular, scleractinian framework-building cold-water corals are apparently rare with very few isolated and small-sized live occurrences of the species Lophelia pertusa and Madrepora oculata. In contrast, dead coral framework and coral rubble are more frequent pointing to a higher abundance of cold-water corals on Coral Patch during the recent past. This is even supported by the observation of fishing lines that got entangled with rather fresh-looking coral frameworks. Overall, long lines and various species of commercially important fish were frequently observed emphasising the potential of Coral Patch as an important target for fisheries that may have impacted the entire benthic community. Hydroacoustic seabed classification covered the entire summit of Coral Patch and its northern and southern flanks (water depth: 560–2660 m and revealed extended areas dominated by mixed and soft sediments at the northern flank and to a minor degree at its easternmost summit and southern flank. Nevertheless, these data also predict most of the summit area to be dominated by exposed bedrock

    This study investigates the microfacies and sequence stratigraphic frame work of the Middle Jurassic Dhruma Formation in outcrops in central Saudi Arabia. The study contributes to the efforts to understand and enhance local and regional stratigraphic relationship and correlation of the Jurassic carbonate sequences and their significance to reservoir description and prediction in the subsurcae. The study describes and characterizes the sedimentology, microfacies and the stratigraphy of Dhruma Formation from outcrop sections having a total thickness of 70 m. Detailed microfacies and high-resolution stratigraphical analysis were carried out to determine microfacies, cyclicity, sequences and staking pattern. The study revealed ten lithofacies namely: oolitic grainstone,bioclastic oolitic grainstone, oolitic grapestone, bioclastic grainstone,foraminiferal packstone, echinoderm packstone, peloidal packstone to grainstone,skeletal wackestone to packstone, mudstone, and marlstone.These lithofacies were grouped into five lithofacies associations that deposited on a carbonate ramp setting. The depositional environment ranging from low energy lagoonal setting to high-energy shoals and banks to low energy outer ramp setting. Five high-resolution composite sequences have been defined and each sequence is composed at the bottom of intercalated mudstone/wackestone that passing up into grainstone lithofacies.The composite sequences range in thickness from 7 to 15 m, while the parasequences range from 0.5 to 1.5 m. The composite sequences extend laterally for a distance of more than 350 m. The overall composite section shows a shallowing upward succession of the 4th to the 5th order high-resolution sequences.The dominant lithofacies are the grainy ones, which constitute 30%, 50% and 80% of the studied sections. Furthermore, the parasequences thickness and their bio-components are increasing towards the top. The muddy lithofacies intensively affected the vertical continuity of the

    Marine turtles are well known for their navigation ability in the open ocean and fidelity to nesting beaches. Green turtle adult females migrate from foraging areas to island nesting beaches, traveling hundreds or thousands of kilometers each way. The marine turtle breeding in the Galapagos Islands is the Green Sea Turtle (Chelonia mydas agassisi); fairly common throughout the islands but with nesting sites located at Las Bachas (Santa Cruz), Barahona and Quinta Playa (Isabela), Salinas (Baltra), Gardner Bay (Española) and Bartolomé Islet. In order to characterize and to identify the geochemical signature of nesting marine turtle beaches in Galapagos Islands, sedimentological, geochemical and rock magnetic parameters are used. A total of one hundred and twenty sand samples were collected in four beaches to relate compositional characteristics between equivalent areas, these are: Las Bachas, Salinas, Barahona and Quinta Playa. Grain size is evaluated using laser particle analysis (Model Coulter LS 230). Bulk ICP-MS geochemical analysis is performed, following trace elements are analyzed: Al, V, Cr, Co, Ni, Cu, Zn, Cd, Ba, Pb, Fe, Mn, K, Na, Mg, Sr, Ca and Hg; and low-field magnetic susceptibility is measured in all samples at low and high frequencies. Granulometric analysis showed that Barahona and Quinta Playa are characterized for fine grained sands. In contrast, Salinas and Las Bachas exhibit medium to coarse sands. Trace metals concentrations and magnetic susceptibility show different distribution patterns in the beach sands. Calcium is the most abundant element in the samples. In particular, Co, K, and Na show similar concentrations in the four beaches. Las Bachas beach shows highest concentrations of Pb and Hg (maximum values 101.1 and 118.5 mg/kg, respectively), we suggest that the enrichment corresponds to an anthropogenic signal. Salinas beach samples show high concentrations of Fe, V, Cr, Zn, Mn and the highest values of magnetic susceptibility (maximum

The sediment record is unusual for the nearly continuous dark- and light-colored laminations (0.1-2.0 cm thick) that comprise the Holocene. Light laminae typically have erosive basal contacts and fine-upwards, whereas dark laminae possess abrupt or gradational lower contacts and reveal no grain size trends. Light laminae contain 7%), and contain 3-10% biogenic silica. Light laminae represent deposition during periods of increased precipitation, mobilization of unvegetated sediment above the lake, and increased stream discharge, all of which generate density-driven undercurrents. Conversely, dark laminae are deposited relatively slowly by sedimentation of organic matter, some derived from surface soil horizons. Time series analysis of light laminae reveal the ENSO spectral signature (2-8 yr) that evolves through the Holocene. However, none of the sediment cores taken from many nearby lakes reveal an alluvial record comparable in terms of frequency and magnitude to that preserved in Pallcacocha thus raising questions as to the factors responsible for the rich stratigraphy preserved in Pallcacocha, and, moreover, the regional paleoclimatic significance of the Pallcacocha record. A review of lacustrine sediment cores obtained from Las Cajas National Park suggests that drainage basin factors are the primary control on the sedimentologic signal recorded. These factors include bedrock geology, presence of unvegetated sediment exposed on slopes, connectivity of exposed sediment to primary inflow streams, drainage basin slope, drainage basin:lake surface area ratio, and position of lake in paternoster sequence of lakes. Bedrock is comprised of Quaternary silicic ignimbrite, rhyolite, and andesite of the Tarqui Formation. Ignimibrite provides the

    This paper presents a detailed sedimentologic investigation of a newly identified, fossiliferous Late Neogene sedimentary succession in the Rukwa Rift Basin, southwestern Tanzania. This synrift deposit is a rare and significant new example of a fossiliferous succession of this age in the Western Branch of East Africa Rift System. The unit, informally termed the lower Lake Beds succession, is late Miocene to Pliocene in age based on cross-cutting relationships, preliminary biostratigraphy, and U-Pb geochronology. An angular unconformity separates the lower Lake Beds from underlying Cretaceous and Oligocene strata. Deposition was controlled by rapid generation of accommodation space and increased sediment supply associated with late Cenozoic tectonic reactivation of the Rukwa Rift and synchronous initiation of the Rungwe Volcanic Centre. The lower Lake Beds, which have thus far only been identified in three localities throughout the Rukwa Rift Basin, are characterized by two discrete lithologic members (herein A and B). The lower Member A is a volcanic-rich succession composed mostly of devitrified volcanic tuffs, and volcaniclastic mudstones and sandstones with minor conglomerates. The upper Member B is a siliciclastic-dominated succession of conglomerates, sandstones, mudstones and minor volcanic tuffs. Detailed facies analysis of the lower Lake Beds reveals various distinctive depositional environments that can be grouped into three categories: 1) alluvial fan; 2) fluvial channel; and 3) flood basin environments, characterized by volcanoclastic-filled lakes and ponds, abandoned channel-fills and pedogenically modified floodplains. Member A represents a shallow lacustrine setting filled by tuffaceous sediments, which grade up into a system of alluvial fans and high-energy, proximal gravel-bed braided rivers. An unconformity marks the contact between the two members. Member B shows an upward transition from a high-energy, gravel-bed braided river system to a sandy

    Recreational turkey hunting exemplifies the interdisciplinary nature of modern wildlife management. Turkey populations in Minnesota have reached social or biological carrying capacities in many areas, and changes to turkey hunting regulations have been proposed by stakeholders and wildlife managers. This study employed discrete stated choice modeling to enhance understanding of turkey hunter preferences about regulatory alternatives. We distributed mail surveys to 2,500 resident turkey hunters. Results suggest that, compared to season structure and lotteries, additional permits and level of potential interference from other hunters most influenced hunter preferences for regulatory alternatives. Low hunter interference was preferred to moderate or high interference. A second permit issued only to unsuccessful hunters was preferred to no second permit or permits for all hunters. Results suggest that utility is not strictly defined by harvest or an individual's material gain but can involve preference for other outcomes that on the surface do not materially benefit an individual. Discrete stated choice modeling offers wildlife managers an effective way to assess constituent preferences related to new regulations before implementing them.

    The Turkish government is in the process of planning two nuclear reactors in Turkey. The Turkish Atomic Energy Authority has been given the task of developing plans for improved control of low-level wastes (LLW) in Turkey. Principal sources of radioactive wastes are hospitals, research institutions, biological research centers, universities, industries, and two research reactors in Turkey. These wastes will be treated in a pilot water treatment facility located in Cekmece Nuclear Research and Training Center, Istanbul. In this temporary waste disposal facility, the wastes will be stored in 200-l concrete containers until the establishment of the permanent waste disposal sites in Turkey in 1990. The PRESTO-II (prediction of radiation effects from shallow trench operations) computer code has been applied for the general probable sites for LLW disposal in Turkey. The model is intended to serve as a non-site-specific screening model for assessing radionuclide transport, ensuring exposure, and health impacts to a static local population for a chosen time period, following the end of the disposal operation. The methodology that this code takes into consideration is versatile and explicitly considers infiltration and percolation of surface water into the trench, leaching of radionuclides, vertical and horizontal transport of radionuclides, and use of this contaminated ground water for farming, irrigation, and ingestion

    Full Text Available Turkey is one of main gene centers in the world for grapes. It is believed that cultivated grapes have their origins in Turkey and the surrounding countries. Vitis vinifera ssp sylvestris is the only wild grape species in this region. That is why Turkey has a very large amount of wild grapevine populations and grape cultivars which offer to grapevine breeders a valuable gene pool. Wild grapevines have significant characters for inducing the resistence to biotic and abiotic stress factors, such as resistance to lime, drought, pests and diseases. Turkey has over 1.600 local grape cultivars, among which the majority of them are conserved at the national grape collection vineyard in Tekirda?. They are mostly used as table grapes, dried grapes or for local consumptions. Wild grapes are distributed all over the country territory, mainly in the river basins and forests. Wild grape collection vineyards were established at some universities in Turkey. These grapevines will be screened for the resistance to biotic and abiotic stress factors.

    Full Text Available Honey is an important source of nutrients and energy and an effective remedy against various human diseases. Honeydew honey is produced from honeydew of phloem-feeders that honeybees gather. In this study, we focused on honeydew producers and diversity of host tree species which are involved in honeydew production in Turkey. A total of 24 honeydew producers by host tree species are identified in Turkey. Of these, 13 coniferous trees and 11 deciduous trees. The main honeydew producer in Turkey is a scale insect, Marchalina hellenica Gennadius (Hemiptera: Margarodidae living mainly on pines (Turkish red pine, Aleppo pine, and rarely on stone pine, Anatolian black pine and Scots pine. Honeydew producer insects can be treated as serious pests of conifer and broadleaf trees. The aphids and the scale insects such as Ceroplastes floridensis, Cinara cedri, C. laportei, Eulachnus rileyi, Icerya purchase, Kermes vermilio, Lichtensia viburni and Saissetia oleae are known as pests in several European, Asian and African countries. Despite their potential harm to their host plants, insect species producing honeydew play an important role in honey production in Turkey. Turkish honey production is exported to EU countries and, furthermore beekeeping is an important part of agricultural sector in Turkey.

    Full Text Available Wind energy applications and turbine installations at different scales have increased since the beginning of this century. As wind energy is an alternative clean energy source compared to the fossil fuels that pollute the atmosphere, systems that convert wind energy to electricity have developed rapidly. Turkey’s domestic fossil fuel resources are extremely limited. In addition, Turkey’s geographical location has several advantages for extensive use of wind power. In this context, renewable energy resources appear to be one of the most efficient and effective solutions for sustainable energy development and environmental pollution prevention in Turkey. Among the renewable sources, Turkey has very high wind energy potential. According to the Organization for Economic Cooperation and Development (OECD Turkey theoretically has 166 TWh a year of wind potential. However the installed wind power capacity is approximately 14% of total economical wind potential. In this study, Turkey’s installed electric power capacity and electric energy production are investigated and also the current situation of wind energy in Turkey is examined. The wind data used in this study were taken from Turkish Wind Energy Association (TUREB for the year 2012. This paper reviews the assessment of wind energy in Turkey as of the end of July 2012 including wind energy applications.

    2017-01-01

    Full Text Available Consumer attitude surveys classified as leading economic indicators aim at extracting information from respondents regarding their perceptions of economic outlook. A typical consumer confidence index includes questions designed to measure the changes in the past-current and current-future pairs of economic outlook perceptions of the participants as well as a question that examines the consumer’s view on the current stage of economic activity. These surveys use equal amount of male and female participants. This paper checks the existence of perceptional difference of genders using CNBC-e consumer confidence index for Turkey. First, we calculate monthly consumer confidence indices for men and women for January 2003 – March 2011. Then, employing this data set, we use the recently developed frequency domain analysis of Breitung and Candelon (2006 and wavelet comovement analysis of Rua (2010 to assess whether these indices follow similar patterns before and after the recent global crisis in time and frequency domain. Our results show that women consistently diverge from men and seem to be on the pessimistic side-due probably to lower levels of wealth in terms of expectation formation. Moreover, this difference is increasing when purchasing durable goods is considered.

  3. An evaluation of inflation expectations in Turkey

    Directory of Open Access Journals (Sweden)

    Barış Soybilgen

    2017-03-01

    Full Text Available Expectations of inflation play a critical role in the process of price setting in the market. Central banks closely follow developments in inflation expectations to implement a successful monetary policy. The Central Bank of the Republic of Turkey (CBRT conducts a survey of experts and decision makers in the financial and real sectors to reveal market expectations and predictions of current and future inflation. The survey is conducted every month. This paper examines the accuracy of these survey predictions using forecast evaluation techniques. We focus on both point and sign accuracy of the predictions. Although point predictions from CBRT surveys are compared with those of autoregressive models, sign predictions are evaluated on their value to a user. We also test the predictions for bias. Unlike the empirical evidence from other economies, our results show that autoregressive models outperform most of inflation expectations in forecasting inflation. This indicates that inflation expectations have poor point forecast accuracies. However, we show that sign predictions for all inflation expectations have value to a user.

  4. Estimating light-vehicle sales in Turkey

    Directory of Open Access Journals (Sweden)

    Ufuk Demiroğlu

    2016-09-01

    Full Text Available This paper is motivated by the surprising rapid growth of new light-vehicle sales in Turkey in 2015. Domestic sales grew 25%, dramatically surpassing the industry estimates of around 8%. Our approach is to inform the sales trend estimate with the information obtained from the light-vehicle stock (the number of cars and light trucks officially registered in the country, and the scrappage data. More specifically, we improve the sales trend estimate by estimating the trend of its stock. Using household data, we show that an important reason for the rapid sales growth is that an increasing share of household budgets is spent on automobile purchases. The elasticity of light-vehicle sales to cyclical changes in aggregate demand is high and robust; its estimates are around 6 with a standard deviation of about 0.5. The price elasticity of light-vehicle sales is estimated to be about 0.8, but the estimates are imprecise and not robust. We estimate the trend level of light-vehicle sales to be roughly 7 percent of the existing stock. A remarkable out-of-sample forecast performance is obtained for horizons up to nearly a decade by a regression equation using only a cyclical gap measure, the time trend and obvious policy dummies. Various specifications suggest that the strong 2015 growth of light-vehicle sales was predictable in late 2014.

    Full Text Available Russian – Turkish relations go deep into the past. From the Cold War and the relations between the Soviet Union and the United States certainly there has not been a more complicated relationship in international relations. Both countries have different strategic positions, a different dominant religion, a different past, but their relationship largely depends on the future of Eurasia. This paper will deal with relations between the two countries since the establishment of the first diplomatic contacts in the 15th century, through the relationship during the time of Peter the Great, and will mention the periods of the First and Second World Wars, as well as the Cold War era. Special attention will be focused on the current relations between the two countries, especially after the conflict in 2015, when Turkey shot down a Russian plane over Syria. Special attention will be focused on energy policy and the potential for building a nuclear power plant in Mersin, and the continuation of Turkish stream. The paper will deal with economics and trade exchange, which have almost disappeared following the 2015 incident, security cooperation and Turkey’s plans to buy the defense system S-400 from Russia, as well as relations between the two countries towards NATO. The paper will end with the projection of the prospects for the economic relations between the two countries.

    2014-07-01

    Full Text Available Among the handicraft, art of being a coppersmith has been occurred intensively in the past. The fast developing socio - economic structure diminished the value and the place of the copper vessels. Heavy and beautiful vessels made by beating left their places to thin, light aluminum, pl astic, glass and steel vessels made by machinery. The demand for copper is diminished. Therefore being a coppersmith has become less and less important every day. However, in the last few years, copper vessels becoming a touristic souvenir became a source of hope for the traditional coppersmith art to live on. Copperworking is applied in our country in some regions and there are people who live off it. Souvenirs, daily used vessels, and requirements of the rural areas are produced in centers such as İstanb ul, Ankara, Tokat, Çorum, Erzincan, Diyarbakır, Kahramanmaraş, Gaziantep, Bursa, Kastamonu, Çankırı, Giresun and Trabzon. The situation of being a coppersmith in Turkey is explained, examples are given from souvenir copper items produced in Ankara, and sug gestions are made to keep this craft alive.

    Domestic violence is accepted worldwide as an important health problem. Besides diagnosis and treatment process, there are difficulties when considering of medico-legal evaluation of pregnant women subjected to domestic violence. As a signatory of the ''Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW)'' Turkey has certain commitments regarding domestic violence and made regulations on national law. The purpose of the present study is to demonstrate the prevalence of domestic violence during pregnancy among the women who applied to obstetrics clinics and evaluating of the participants' knowledge level about the legal legislation concerning domestic violence. Pregnant women attending for antenatal care to department of Gynecology and Obstetrics were interviewed using an anonymous and confidential questionnaire. The questionnaire used was a version of Abuse Assessment Screen with guidance of references. 28 (13.4%) women stated that they had been subjected to violence before pregnancy. Only 10 (4.67%) women had stated experience of violence during pregnancy. 148 (69.2%) of them had stated that they had no knowledge about any legislation concerning domestic violence in our country. We believe that society awareness should be increased and the health workers should be informed about their ethical and legal responsibilities concerning domestic violence during pregnancy. The knowledge and sensitivity of health care personnel in Prenatal Clinics and Family Planning Services should be increased and examination protocols should be provided about domestic violence against pregnant women.

    In recent years, psychological problems that are caused by working conditions, like burn out syndrome, are more commonly observed. In our study, we aimed to evaluate mobbing exposure, factors causing mobbing and precautions for mobbing in residency students who are educated in anaesthesiology and reanimation clinics in Turkey. After obtaining consent from the ethics committee, we sent our questionnaires to the secretariats of the departments by postal mail. Completed questionnaires were collected in our department's secretariat blindly and randomly mixed. One hundred and one participants were returned the questionnaires. Data was statistically analysed in SPSS 21.0 software programme. During residency programme, sated to have experienced mobbing one or more time. Interestingly, 5.9% participants complained of physical mobbing. Mobbing exposure was more common in females. The most serious new onset psychosomatic symptoms stated during residency were committing suicide (2%), addiction (16%), severe depression (18%), panic attack (8%), more accidents (7%) and tendency of violence (15%). In mobbing group there was statistically significant dissatisfaction rate. In professions where mobbing is common, incidences of psychiatric diseases and suicide attempts are high are increased. Who are under risk for experiencing mobbing should be noticed carefully to ensure good judgement and problems should be inspected objectively in a detailed manner. Anesthesiology societies and other medical professional societies should establish mobbing committees. Thus, mobbing problems can be resolved and healthy career oppurtunities can be presented to residents.

    Landfill gas (LFG)-to-energy plants in Turkey were investigated, and the LFG-to-energy plant of a metropolitan municipal landfill was monitored for 3 years. Installed capacities and actual gas engine working hours were determined. An equation was developed to estimate the power capacity for LFG-to-energy plants for a given amount of landfilled waste. Monitoring the actual gas generation rates enabled determination of LFG generation factors for Turkish municipal waste. A significant relationship (R = 0.524, p kitchen waste generation behaviors influenced by the ambient temperature. However, no significant correlation was found between the ambient temperature and the generated LFG. A temperature buffering capacity was inferred to exist within the landfill, which enables the anaerobic reactions to continue functioning even during cold seasons. The average LFG and energy generation rates were 45 m 3 LFG/ton waste landfilled and 0.08 MWh/ton waste landfilled, respectively. The mean specific LFG consumption for electricity generation was 529 ± 28 m 3 /MWh.

    2017-12-01

    This paper discusses the crucial effects of Turkish health and migration laws on Syrian refugees' access to public health services and social determinants of health. Key aspects of current Turkish laws affect the health of both refugees and Turkish citizens in many ways. The huge influx of refugees is increasing communicable disease risks, overcrowding hospitals, and more generally straining financial and health resources. Turkey's United Nations membership and its candidacy for European Union (EU) have led to increased alignment of Turkey's refugee and migration policies with international law. Major differences remain, however, and Turkey's remaining noncompliance with international refugee laws is a major force driving Syrian refugee's flight to EU countries, as refugees desperately seek the right to better health and social services.

    Full Text Available This paper compares and contrasts the policy reform experiences of Poland and Turkey en route to high income. For both countries, globalization has presented unprecedented opportunities to catch up, unleased by integration into European and global markets and the establishment of macroeconomic discipline. These opportunities were reinforced by the creation of economic institutions to strengthen competition and support private entrepreneurship, catalyzed by the convergence process with the European Union. Both Poland and Turkey have shown resilience following the 2008 global crisis, but continued success will require renewed structural reform measures. Dealing with the challenging of aging while at the same time finding a way to sustain productivity growth through greater domestic innovation is shaping Poland’s policy agenda. Turkey's structural and demographic potential as well as its strategic location between the markets of Europe and Asia offers attractive value proposition to investors, which could be further enhanced with improvements in business regulations and economic governance.

    Full Text Available Chlamydiosis is a contagious disease of birds, mammals, reptiles and humans. So far it was demonstrated in 469 species of birds and among them, turkeys are the most susceptible domestic poultry species. The disease appears in epizootic form in intensive turkey farming. Since commercial poultry rearing is under-developed in Bosnia and Herzegovina, our investigation was based on extensively reared turkeys. Cloacal and oropharyngeal swabs were taken from 26 birds and infection was proven by common chlamydial LPS antigen detection tests (IDEIA and CW. We have used rRT-PCR technique targeting chlamydial ompA gene region in order to prove Chlamydia species. Five birds, (19.2% were found positive as judged by IDEIA and CW tests. Among them one was positive Cp. psittaci speciesspecific rRT-PCR, ompA gene.

    Turkey's Energy Efficiency Law (EEL) came into force in May 2007. The EEL will transform energy policies implemented in the government and private sectors. The law and upcoming regulations will offer opportunities for the impending Energy Service Company (ESCO) market in Turkey. In this work, we briefly review the ESCO literature and its financing mechanisms in the world, and present our views with regard to the funding and related risks that are likely to be associated with the forthcoming Turkish ESCO market. These views are backed up with Turkish credit and banking market performance and the lessons learned from implementation of some EU-related projects involving the banking sector and small-and-medium-sized firms. We conclude that in order to create a promising competitive ESCO market, Turkey's policy must be to sustain its average 5% growth rate achieved lately for the coming decade, finish the structural reforms which will invite necessary capital inflows to ensure an economic stability and financing

    It is estimated that if there is no alternative energy source, there will be increase in building nuclear energy power plants. This source of energy and know how along with technology must be put into the possession of Turkey. Since almost all of Turkey is 1 st degree earthquake region and in view of the regional political instability, the requirement of ample amount of water for prolonged times, the density of settlement, environmental problems, high cost of building nuclear energy power plants it becomes necessary to think about their application techniques. In this study, mobile nuclear energy power plants having a wide area of use in conditions prevailing in Turkey , their draft drawings for making them by using metal/steel are shown. The positive-negative aspects of the topic is presented for discussions

    Full Text Available Even though the discussion of conscientious objection, the refusal of military service due to individual’s moral values or religious beliefs, is new in Turkey, the subject has become the focus of intense interest. The discussion of conscientious objection in Turkey has come the to the fore with the heated debates between the glorification of the dynamics of Turkish social structure towards military service and the critique of militarism and conscientious objection’s legal dimensions, as well. Since the reduction of discussions in this context in Turkey to the legal dimension is the ignorance of social reality constituting basis to the legal dimension, the subject is examined with reference to the social and historical outlook on this issue and the study is built on dimensions.

    Full Text Available A sequence of pelagic limestone, calciturbidite, debris flow, greywacke, basalt and limestone blocks. up to several hundred metres across, occur west of the town of Biga in northwest Turkey. The pelagic limestones in this sequence, named as the Ballıkaya formation, comprise pelagic foraminifera of Palaeocene age. Neritic limestone of Mid-Eocene age lies unconformably over the Ballıkaya formation. The age and the sedimentary environment of the Ballıkaya formation indicate the presence of a tectonically active deep-sea environment in northwest Turkey during the Palaeocene, and constrain the main Alpide deformation in northwest Turkey to the Late Palaeocene - Early Eocene interval.

    Full Text Available Turkey has made in the last 4 decades a remarkable growth in economy. The energy industry is represented mainly by the coal industry (especially lignite and coal, located in northwest Anatolia. The electricity is produced in the hydro and thermal power plants. Turkey has the world's 17th largest nominal GDP, and 15th largest GDP by PPP. The country is a founding member of the OECD (1961 and the G-20 major economies (1999. Since December 31, 1995, Turkey is also a part of the EU Customs Union. While many economies have been unable to recover from the recent global financial recession, the Turkish economy expanded by 9.2% in 2010, and 8.5 percent in 2011, thus standing out as the fastest growing economy in Europe, and one of the fastest growing economies in the world. Hence, Turkey has been meeting the “60 percent EU Maastricht criteria” for public debt stock since 2004. Similarly, from 2002 to 2011, the budget deficit decreased from more than 10 percent to less than 3 percent, which is one of the EU Maastricht criteria for the budget balance. As of 2012, the main trading partners of Turkey are Germany, Russia and Iran. Turkey has taken advantage of a customs union with the European Union, signed in 1995, to increase industrial production for exports, while benefiting from EU – origin foreign investment into the country. Turkey is also a source of foreign direct invest-ment in central and eastern Europe and the CIS, with more than $1.5 billion invested. 32% has been invested in Russia, primarily in the natural resources and construction sector, and 46% in Turkey’s Black Sea neighbours, Bulgaria and Romania. Turkish companies also have sizable FDI stocks in Poland, at about $100 million. The construction and contracting companies have been significant players, such as Enka, Tekfen, Gama, and Üçgen İnşaat, as well as the three industrial groups, Anadolu Efes Group, ŞişeCam Group and Vestel Group. The exports reached $115.3 billion in

    Full Text Available This article examines the impact of political globalization on foreign direct investment inflows to Turkey. Existence of foreign missions in a country, membership in international organizations, participation in U.N. Security Council Missions, and International Treaties are all seen as indicators political globalization. Using different econometric techniques, this study aims to find out whether any empirical relationship between political globalization and FDI exists. The analysis in this article covers the period in Turkey between 1970-2012. The results of cointegration analysis provide no an evidence of a long-run or short run any relationship political globalization and FDI.

  8. Health and social inequities in Turkey.

    Dedeoglu, N

    1990-01-01

    Social and economic policies of governments directly influence the health of the people. These policies, in turn, are determined by the national and foreign controllers of power. Economic and social factors in Turkey during the late 1970s led to a new modelling of the economic system, from a Keynesian to a market-oriented and monetarist model. The state mechanism was also altered to form a centralized, authoritarian regime in order to enforce the requirements of the economy. As a result, the middle class diminished in size, inequalities in income distribution increased, unemployment climbed, the purchasing power of wage earners decreased, government spending for education and health was cut and new oppressive laws were enacted. Health services were already urban-biased and hospital-oriented, but new free-market measures were instituted which promoted private health institutions and attempted to transform state-owned and financed hospitals into self-supporting, independent business enterprises. The only school of public health was closed down; preventive medicine expenditures were lowered while hospital rates and drug prices were increased. All these changes affected the health status of the population. Mortality and morbidity inequalities had already existed between the rich and the poor, men and women, urban and rural settlements, educated and illiterate, West and East, always in favour of the former. However, the new policies exacerbated the inequities. Infectious diseases including tuberculosis increased, nutrition worsened, occupational diseases and work accidents rose to be the highest in Europe. The power-holding minority is not interested in the health of populations and is committed to pursue its social and economic policies. Ad hoc research, especially cross-sectional mortality studies repeated at regular intervals can provide data on the most vulnerable groups as no other valid information exists. There is little hope of these data being used for

    Full Text Available Geostrategic integrity of the Balkans and the Danube region and the strategic ambitions of powerful countries that were inherited from previous centuries define the start points of European streams in XX century. German 'drang nach osten', Russian spread to south and an ambition of primate in struggle for the Turkish heredity, Turkish strivings to bring its Empire out of death with reforms, and remain right-sided to Sava-Danube river basin, preserving it as its natural border, and the strivings of Balkan peoples for liberation, shaped geopolitical, strategic and state-legal traits of the phenomenon called 'Eastern question'. The conquests form south east towards north and northwest and vice versa pointed that geostrategic traits of Balkans were not separation and geographic in-connectivity, but connection and permeation, which open strategic ways to domination over the Eurasian knot and warm seas of Mediterranean and Middle East. The fact that Balkans aren't the only connection between Europe and Asia does not lessen their geostrategic and geopolitical importance. On the contrary. This question, that was an eastern one for powerful countries, and one of a life importance for the people of southeast Europe, goes back into deep past. It was formed and a geostrategic position of a whole area that it related to by conflicted interest of people, religions and whole civilizations that faced each others there. However, if looking for a more narrow historical sense of the term Eastern question, we will find it in a collision of Europe and Islamic world, which was brought by Turkish penetration into Europe. During the rise of the Ottoman Empire, it was a matter of survival of European countries that were struck by Ottoman conquest, and after the decline of the Ottoman power it turned into a struggle for Turkish heredity. Today, the Struggle form Ottoman heredity strongly includes Turkey as well. Turkish engagement in a struggle for its own historical

    This study assesses the results of environmental radioactivity measurements for Bayburt Province in the Eastern Black Sea area of Turkey. Using γ-ray spectrometry, activity concentrations of the natural radionuclides 226 Ra, 232 Th and 40 K and a fission product 137 Cs were investigated in soil samples. The activity concentrations of 226 Ra, 232 Th and 40 K in various building materials such as sand, cement and marble and in drinking waters were determined. The activity concentrations vary from 16 to 54 Bq kg -1 for 226 Ra, from 10 to 21 Bq kg -1 for 232 Th and from 113 to 542 Bq kg -1 for 40 K in building materials. The mean specific activity concentrations of 226 Ra, 232 Th and 40 K in drinking waters were 93, 30 and 504 mBq l -1 , respectively. The concentrations of gross α and β radioactivity in drinking water samples collected from four different sampling stations have been determined. The results show that the gross α and β activities are lower than the screening levels given by the World Health Organization (WHO), which are a maximum contaminant level of 0.5 Bq l -1 and 1.0 Bq l -1 gross α and β radioactivity, respectively, in drinking water. Indoor radon measurements were made in 44 dwellings in Bayburt by using Cr-39 detectors. Radon concentrations in dwellings in Bayburt varied from 17 to 125 Bq m -3 and the average value was 56 Bq m -3 . The results obtained in this study indicate that the region has a background radiation level that is within the typical natural range and shows no significant departures from other parts of the country.

    Achieving an adequate level of planning and preparedness for terrorist events involving unconventional weapons, such as the intentional release of nuclear, radiological, biological, and/or chemical agents is a great challenge for Turkey. However, since bioterror agents possess different properties than other conventional attacks like the need for decontamination and the need for personal protective equipment, etc., special plannings should be made where various governmental organizations should be involved. First response against a bioterror attack is commonly given by local or regional organizations. Some of the following reactions include quick notification of authorities, establishment of a local crisis management center, information to public, medical management and decontamination, quarantine measures, evacuation to hospitals for suspected cases, forensic measures, social aids to victims Laboratory management is essential for bioterror attacks, so that the treatment or prophylaxis of injured cases with the organism can be performed properly. Therefore, an accredited reference laboratory should be set up for final diagnosis. Although much progress has been made in this regards, much work remains be to done in terms of ensuring adequate level via bioterror drills, adequate hospital-based decontamination unit and negative pressure isolation bed capacities, and adequate hospital-based stockpiles of personal protective equipment, drugs, vaccines and ventilators. From this point of view, potential organizations which are supposed to be assigned in this event must have task-oriented official departments and the roles should be outlined in detailed. Within this connection, a scenario simulating a bioterrorist attack and describing the response and coordination developed is schematised. (author)

    Full Text Available Home care services can be provided as an alternative to institutional care to people, in case of their demand, who need care because of aging and chronic diseases. Structured home care service in health system does not exist in Turkey. Relatives try to provide care at home to those people. In this cross-sectional study, household was selected as a sampling unit, determining prevalence of home care at the households and gathering some information about home care in Cankaya district of Ankara was intended. It was found that in one-month period before this study was carried out, home care services were provided at 8.7% of the households in Cankaya district. 62.5% of people who received home care service were women, 15.3% of them were belonging to 65-74 age group; 31.7% of those were illiterate and 12.5% had no social and health insurance. Among people, 15.4% were receiving home care after surgical operation, 15.4% were receiving care because of stroke and cerebrovascular diseases and 9.6% were cancer patients. 81.7% of adults who were taken care at home were found to be dependent at different levels while performing daily living activities, the most common treatment method was detected as oral medication (81.4%. These people were in need of preventive, curative and rehabilitative and supportive services. A home care service model, which takes into consideration the social characteristics of the country, should be developed at this district where there is a large elderly population.

    Land consolidation (LC) represents complexity if management, legal, economic and technical procedures realized in order to adjust the land structure according to actual human preferences and needs. It includes changes in ownership rights to land and other real estate property, exchange of parcels among owners, changes in parcel borders, parcel size and shape, joining and dividing of parcels, changes in land use, construction works as roads, bridges, water changes etc.. Since the subject of LC is agricultural lands, the quality of consolidation depends on the quality of soil data. General Directorate of Agrarian Reform (GDAR) is the responsible institution on land consolidation whole of Turkey. Under GDAR, National Soil Information System (NSIS) has been build up with base soil data in relevant scale (1:5000). NSIS contain detailed information on soil chemical and physical properties, current land use, parent material, land capability class, Storie Index Values. SI were used on land consolidation, land use planning and farm development services. LCC was used for land distribution, rental land; define of village settlement, consolidation, expropriation, reconstruction, reclamation, non-agricultural usage. LCC were also specified to subclasses in four different limited factors as i) flow and erosion risk ii) requirement of drainage and soil moisture iii) Limits of soil tillage and root (shallow soils, low water retention capacity, stony, salty .etc) iv) climatic limits. In this study, digital soil survey and mapping project located in Yumurtalik, Adana is presented as an example of NSIS data structure. The project cover an area of 45709 ha that include crop lands as an area of 28528 ha and other land use (urban, roads..etc) as an area of 17181 ha. Soil profiles were described in 45 different points and totally 1279 soil samples were collected in field study and the check bore hole were made in 3170 points.

    The economic potential for unconventional shale oil and gas production in the Silurian of the Berkine - Ghadames and Illizi basins (BGI) in south-eastern Algeria has been recently confirmed through exploration drilling. The aim of the present paper attempts a better understanding of the Intra-Tassilian depression within the entire Silurian of the Tassili n'Ajjer plateau. The continuous deposits of the Silurian are exposed at the southern margin of the prolific BGI basins, in the Tassili n'Ajjer plateau, offering the chance to understand the sedimentology, ichnology, and to present a detailed sequence stratigraphy framework for the region. The 410 m-thick clastic Silurian sedimentary strata are subdivided into three formations in the context of sequence stratigraphy, namely: (i) the Oued Imihrou Fm. (Llandoverian) overlain by (ii) the Atafaïtafa Fm. (late Llandoverian to Wenlockian), and (iii) the Oued Tifernine Fm. (late Wenlockian to Pridolian). These can be also distinguished across the entire investigated area and laterally traceable over kilometers. Clear cyclic stacking patterns are identified within the four studied sections showing progressively a general trend of thickening- and coarsening-upward, over a complete 2nd-order megasequence (SIL-1 MS). This transgressive-regressive succession suggests deltaic progradation, shallowing and basin infilling as evidenced by numerous diagnostic sedimentary features and trace fossils, largely from eastern-to western-Tassili plateau. Indeed, the wealth of outcrop data in the Silurian siliciclastic succession enables us to distinct thirteen facies (facies A-M), ranging from shallow-to marginal-marine facies, and in turn, grouped into six facies associations (FA1-FA6). The lowermost part of the succession, which is the most prolific sources of hydrocarbons in North Africa, consists of thick organic-rich graptolite-yielding black 'hot' shales and 'lean' shales with sparse bioturbation with small Thalassinoides belonging

    The Colorado River in the southwestern U.S. provides an excellent natural laboratory for studying the origins of a continent-scale river system, because deposits that formed prior to and during river initiation are well exposed in the lower river valley and nearby basinal sink. This paper presents a synthesis of regional stratigraphy, sedimentology, and micropaleontology from the southern Bouse Formation and similar-age deposits in the western Salton Trough, which we use to interpret processes that controlled the birth and early evolution of the Colorado River. The southern Bouse Formation is divided into three laterally persistent members: basal carbonate, siliciclastic, and upper bioclastic members. Basal carbonate accumulated in a tide-dominated marine embayment during a rise of relative sea level between ~ 6.3 and 5.4 Ma, prior to arrival of the Colorado River. The transition to green claystone records initial rapid influx of river water and its distal clay wash load into the subtidal marine embayment at ~ 5.4–5.3 Ma. This was followed by rapid southward progradation of the Colorado River delta, establishment of the earliest through-flowing river, and deposition of river-derived turbidites in the western Salton Trough (Wind Caves paleocanyon) between ~ 5.3 and 5.1 Ma. Early delta progradation was followed by regional shut-down of river sand output between ~ 5.1 and 4.8 Ma that resulted in deposition of marine clay in the Salton Trough, retreat of the delta, and re-flooding of the lower river valley by shallow marine water that deposited the Bouse upper bioclastic member. Resumption of sediment discharge at ~ 4.8 Ma drove massive progradation of fluvial-deltaic deposits back down the river valley into the northern Gulf and Salton Trough.These results provide evidence for a discontinuous, start-stop-start history of sand output during initiation of the Colorado River that is not predicted by existing models for this system.

    2010-12-01

    The early-to-middle Holocene outcrops of Izu-Oshima island, 100 km SSW of Tokyo, comprise sand- to gravel-size pyroclasts, and exhibit undulating layered structures, with each wavelet typically measuring 5-10 m high. These outcrops were traditionally interpreted as exemplary subaerial "ash-fall" deposits in volcanology textbooks (e.g. Schmincke 2006). Our detailed sedimentological analyses, however, have revealed that it is of pyroclastic density-current origin, the majority of which formed in shallow-marine settings. The present study focuses on the outcrops along the western coast of the Island, where the three-dimensional architecture of the outcrops is superbly exposed, and the existing archaeological framework provides a reliable chronostratigraphic control. The outcrops contain abundant compound bedforms, where small bedforms (dunes/antidunes) occur within the larger bedforms. The compound bedforms exhibit four-fold hierarchy (ranks 1 to 4), and bedforms for each scale display dominantly upstream-accreting geometry. The largest scale (Rank 1) of these bedforms show wavy parallel-bedding geometry (each wavelet typically measuring 5-10 m high and 50-100 m wide). We interpreted the large-scale architecture as sediment waves (gigantic antidunes) similar to the one reported from the shallow-marine deposits associated with AD 79 Mt. Vesuvius eruptions (Milia et al. 2008). Moreover, we have identified crustacean burrows and other trace fossils indicative of a nearshore shallow-marine environment. The pervasive occurrence of these fossils throughout the outcrops and abundant water-escape structures also suggests their subaqueous origin. On the other hand, evidence of subaerial deposition (e.g., paleosols and rootlets) or subaerial reworking (e.g., lahar) is absent, except for some spots on several regional unconformities that divide 10’s-m-thick sediment-wave deposits. On some of these unconformities, ribbon- to fan-shaped lava and/or ancient human-dwelling sites

    2006-10-15

    This article deals with overview of Turkey's coal necessity, reserves and utilization. Turkey is rapidly growing in terms of both its economy and its population. In parallel, its demand for energy, particularly for electricity, is increasing. Turkey possesses fossil fuel resources of hard coal (HC) and lignite (LG) have the greatest importance in energy production and for the national economy. The hard coal and lignite reserves of Turkey are 1.126 and 8.375 millions tons(Mt), respectively. Coal, the major fuel source for Turkey utilized mainly for electric power, steel manufacturing and cement production, amounts to 31% of total energy consumption in Turkey. To sum up, providing the total consumption is taken into account in the Middle East, the coal consumption rate of Turkey is approximately 90% of the consumption in this region.

    Full Text Available This paper is an analysis of milk support policy in the European Union and in Turkey. Turkey’s adaptation of its milk policy to the Common Agricultural Policy of European Union is on the agenda since Turkey has been a candidate country in 1999. Regarding that the Common Agricultural Policy has been reformed many times, Turkey has to adapt its milk sector to a changing policy. Turkey, on the other hand, pursues different support policy in the milk sector. The producers, who are registered in the Farming Registration System, receive milk incentive premiums. There are no similarities between Turkish milk support policy and European Union’s milk support policy. According to the last progress reports, Turkey has to improve Farming Registration System.

    Late Preclassic (300 BC-AD 100) turkey remains identified at the archaeological site of El Mirador (Petén, Guatemala) represent the earliest evidence of the Mexican turkey (Meleagris gallopavo) in the ancient Maya world. Archaeological, zooarchaeological, and ancient DNA evidence combine to confirm the identification and context. The natural pre-Hispanic range of the Mexican turkey does not extend south of central Mexico, making the species non-local to the Maya area where another species, the ocellated turkey (Meleagris ocellata), is indigenous. Prior to this discovery, the earliest evidence of M. gallopavo in the Maya area dated to approximately one thousand years later. The El Mirador specimens therefore represent previously unrecorded Preclassic exchange of animals from northern Mesoamerica to the Maya cultural region. As the earliest evidence of M. gallopavo found outside its natural geographic range, the El Mirador turkeys also represent the earliest indirect evidence for Mesoamerican turkey rearing or domestication. The presence of male, female and sub-adult turkeys, and reduced flight morphology further suggests that the El Mirador turkeys were raised in captivity. This supports an argument for the origins of turkey husbandry or at least captive rearing in the Preclassic.

    The geochemistry dispersion of the metals in aquatic environment is related to the physical chemistry proprieties of these elements as to their interaction by sorption on and desorption from solid particles. These interaction must be understood within the environmental dynamic, with its hydrological, sedimentological, chemical, physical and biological processes that may take the toxic elements (stables metals and radionuclides) to the bio alimentary chain. It was observed at the Ribeira Bay, its hydrodynamic behaviour through the suspension material and particulate organic carbon dispersion. And, through the textural, mineralogical and chemical parameters it was observed the behaviour of the geochemistry processes of the sedimentary materials and the influence that they may submit to the metals dispersion.

    Full Text Available The sedimentology and paleoenvironment of the Deba-Fulani Member of the Pindiga Formation were investigated on the basis of their grain size distribution. Granulometric analysis has indicated that the samples are generally well to moderately sorted with skewness values ranging from negatively to positively skewed which may indicate influence of both marine and fluvial conditions. Bivariate plot relationships of standard deviation vs. mean, standard deviation vs. skewness, first percentile vs. mean also indicated both fluvial and marine setting for the middle part of the Pindiga Formation member. However, most of the bivariate plot showed dominance of fluvial environment. The probability curve plot shows a prevalence of three-sand population curves which are usually associated with wave processes indicating marine conditions for most part of the Deba-Fulani Member.

    In this study, energy utilization and its major environmental impacts are discussed from the standpoint of sustainable development, including anticipated patterns of future energy use and subsequent environmental issues in Turkey. Several aspects relating to energy utilization, renewable energy, energy efficiency, environment and sustainable development are examined from both current and future perspectives. Turkey is an energy importing country, more than half of the energy requirement has been supplied by imports. Domestic oil and lignite reserves are limited, and the lignites are characterised by high ash, sulfur and moisture content. Because of increasing energy consumption, environmental pollution is becoming a serious problem in the future for the country. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions for sustainable energy development and environmental pollution prevention in Turkey. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources. Especially hydropower, biomass, geothermal, solar and wind energy should be considered and seriously supported by governments and private sectors.

    Full Text Available In our globalizing and rapidly changing world thanks to the communication technologies, Turkey has a significant strategic position in terms of socio-cultural and economical aspects. Therefore, Turkey has a different commercial and political relationship with many countries comprising various cultures and languages. In order to maintain these relations healthfully, interpreting is of utmost importance. Turkey’s membership application for EU shows that Turkey is now an important political power. Besides, commercial contacts with other countries are on the rise and foreign people pay a visit to our country for health tourism. On the other hand, conflicts in neighboring countries increase. All of these factors raise the demand for interpreting in Turkey. In this respect, considering aforementioned explanations we believe that contents of the interpreting courses in academic translation institutions must be refreshed and updated, while doing so, market conditions must also be taken into account. This study deals with interpreting courses offered at Sakarya University taking the above-mentioned suggestions into consideration. In this study, we aim to evaluate interpreting courses in terms of the developments in academic interpreter training and interpreting profession. Hence, curricula of Translation & Interpreting (Studies Departments were compared to each other and the findings are discussed.

    The advantages of power trade between countries, which are attainable for various facts, are distinguished now. Daily differences in the peak-load times of neighboring countries commonly occur for differences in the longitudes of their location. Seasonal differences are also caused by differences in the latitudes leading to different climates. Consequently, different load curves help to have such a production schedule that reduces blackouts and investments for power generation by planning for a proper trade between countries in a region. This paper firstly describes the methodology and framework for the power trade and then the results of an optimal power trade model between Iran and Turkey, which shows a potential benefit for both countries by peak shaving, are presented. The results, in the worst case design, represent optimality of about 1500 MW electricity export from Iran to Turkey at the Turkish peak times, as well as 447 MW electricity import from Turkey at the Iranian peak times. In addition, results derived from running a Long-Run model show that there will be greater potential for power export from Iran to Turkey, which is a guideline of an energy conservation strategy for both countries in the future.

    Currently, considerable attention has been focused on the energy sources and energy studies in Turkey. Indigenous energy consumption accounts for 37% of total energy consumption. The Turkish government's investment needs in the energy sector for the period 2000-2010 will be around 55 billion US dollars. Of this, about 81% is total planning investments. Conventional financing of major infrastructure projects would only increase the amount of foreign credit, thus the Ministry of Energy and Natural Resources (MENR) has conceived other options for financing projects. One option is the so-called Build, Operate, and Transfer (BOT) model, where private investors build and operate private sector generation for certain number of years, at which point they transfer ownership to the state. In June 1996, MENR introduced the Build, Own, and Operate (BOO) financing model. A major dilemma now faced by Turkey is how to invest in new electric power capacity while at the same time adhering to foreign debt ceilings to under lending rules set by the International Monetary Fund. Turkey has to adopt new long-term energy strategies to reduce the share of fossil fuels in the primary energy consumption. Recently, the development of alternative energy sources has been a major focus of the research effort in Turkey.

    Non-renewable fossil-fuel energy resources such as petroleum, coal and natural gas cause environmental damage as a result of carbon dioxide emissions. Due to the trend of increasing energy consumption, air pollution is becoming a significant environmental concern for the future. In order to protect the ecological equilibrium of the natural environment, alternative energy sources must be sought and further developed. In Turkey, hydraulic, solar, and geothermal and biomass (wood, animal and plant wastes and solid wastes), biogas (methane) are potential renewable energy resources. Turkey does not have enough energy resources and is in need of a solution to reduce, re-use or recycle solid wastes. This paper evaluated the amount of solid wastes in Eskisehir, Turkey for producing electricity using the build, operate and transfer (BOT) model. The purpose of the study was to develop an economically useful approach to using wastes while preventing harmful effects on the environment. The paper discussed the burning waste situation in Turkey and other countries and the costs of establishing burning garbage foundations. It was concluded that electricity production from Eskisehir's garbage wastes with benefit the community from both a health angle and economical angle. 17 refs., 8 tabs., 2 figs.
