Late Jurassic low latitude of Central Iran: paleogeographic and tectonic implications

Science.gov (United States)

Mattei, Massimo; Muttoni, Giovanni; Cifelli, Francesca

2014-05-01

The individual blocks forming present-day Central Iran are now comprised between the Zagros Neo-Tethys suture to the south and the Alborz Palaeo-Tethys suture to the north. At the end of the Palaeozoic, the Iranian blocks rifted away from the northern margin of Gondwana as consequence of the opening of the Neo-Tethys, and collided with Eurasia during the Late Triassic, giving place to the Eo-Cimmerian orogeny. From then on, the Iranian block(s) should have maintained European affinity. Modern generations of apparent polar wander paths (APWPs) show the occurrence in North American and African coordinates of a major and rapid shift in pole position (=plate shift) during the Middle-Late Jurassic. This so-called monster polar shift is predicted also for Eurasia from the North Atlantic plate circuit, but Jurassic data from this continent are scanty and problematic. Here, we present paleomagnetic data from the Kimmeridgian-Tithonian (Upper Jurassic) Garedu Formation of Iran. Paleomagnetic component directions of primary (pre-folding) age indicate a paleolatitude of deposition of 10°N ± 5° that is in excellent agreement with the latitude drop predicted for Iran from APWPs incorporating the Jurassic monster polar shift. We show that paleolatitudes calculated from these APWPs, used in conjunction with simple zonal climate belts, better explain the overall stratigraphic evolution of Iran during the Mesozoic.

Iceland’s natural resources include an abundance of geothermal energy and hydropower, of which only 10 to 15 percent is currently being utilized. These are clean, renewable sources of energy. The cost to convert these resources to electricity is relatively low, making them attractive and highly marketable for industrial development, particularly for heavy industry....

Moral panic in Icelandic society: Arrival of ecstasy to Iceland

Directory of Open Access Journals (Sweden)

Jónas Orri Jónasson

2014-12-01

Full Text Available The use of illegal drugs has often been shown to ignite fear and insecurity in society. When a new drug appears the media typically reports on this drug and the risk it poses. Soon after ecstasy appeared in Iceland in the 1990s its use created a major public uproar and insecurity in Icelandic society. In the article the theory of moral panic will be used to examine if the arrival of ecstasy to Iceland ignited a moral panic. Media reports on ecstasy, public reactions, interest groups and government institutions will be analysed. Discourse analysis is employed on newspaper reporting on ecstasy between 1985 and 1997 to detect signs of moral panic. The main conclusion is that evidence suggests that a moral panic existed in Iceland as described in well-known theories on the subject.

2015-02-06

© 2015 The Authors. Earth\\'s present-day response to enhanced glacial melting resulting from climate change can be measured using Global Positioning System (GPS) technology. We present data from 62 continuously operating GPS instruments in Iceland. Statistically significant upward velocity and accelerations are recorded at 27 GPS stations, predominantly located in the Central Highlands region of Iceland, where present-day thinning of the Iceland ice caps results in velocities of more than 30mm/yr and uplift accelerations of 1-2mm/yr². We use our acceleration estimates to back calculate to a time of zero velocity, which coincides with the initiation of ice loss in Iceland from ice mass balance calculations and Arctic warming trends. We show, through a simple inversion, a direct relationship between ice mass balance measurements and vertical position and show that accelerated unloading is required to reproduce uplift observations for a simple elastic layer over viscoelastic half-space model.

BABA SENOWBARI-DARYAN

1997-11-01

Full Text Available Some small-scaled Norian-Rhaetian reefs and reef mounds are imbedded within the shales, siltstones and siliciclastic-carbonate deposits of the Nayband Formation in central Iran. These deposits belong to the central Iranian plate as part of the Cimmerian Continent. Most of the biogenic rocks have a biostromal geometry, biohermal constructions are rare. Inozoid, sphinctozoid, and chaetetid sponges are, beside of corals and other reef builders, the most important reef organisms within these bioconstructions. In some reefs a variety of hexactinellid sponges also occur. The following inozoid sponges are described in this paper: Radiofibra norica n. sp., Permocorynella maxima n. sp., ?Sestrostomella robusta, Marawandia iranica, n. gen., n. sp. and Enaulofungia? triassica n. sp. The first four taxa are among the most abundant sponges within the Nayband Formation where it is exposed in several localities in central Iran. Enaulofungia? triassica, however, is not an abundant sponge there. These inozoid sponges have never been reported from the Triassic deposits of this region. Radiofibra, until now known only from the Upper Permian of Djebel Tebaga (Tunisia, is reported here for the first time from Triassic rocks. The stratigraphic as well as the paleogeographic distribution of all the genera are discussed.   

Alteration in the IRDP drill hole compared with other drill holes in Iceland

Kristmannsdóttir, Hrefna

1982-08-01

The overall alteration pattern in the drill hole at Reydarfjördur is very similar to alteration patterns observed in Icelandic geothermal areas and in low-grade metamorphosed basalts in deep crustal sections elsewhere in Iceland. However more detail is obtained by the study of the IRDP drill core than by study of drill cuttings sampled in previous drill holes in Iceland. A comparatively high fossil thermal gradient is obtained at Reydarfjördur by a combination of mineral stability data and the observed occurence of secondary minerals. This high gradient is consistent with the measured dike dilation at the drill site and the location of the drill site adjacent to a central volcano.

Oxygen isotope ratios of the Icelandic crust

International Nuclear Information System (INIS)

Hattori, K.; Muehlenbachs, K.

1982-01-01

Oxygen isotope ratios of hydrothermally altered basalts from depth of up to approx.3 km are reported from three localities in Iceland: International Research Drilling Project (IRDP) core at Reydarfjordur, eastern Iceland (Tertiary age); drill cuttings from Reykjavik (Plio-Pleistocene age); and Halocene drill cuttings from the active Krafla central volcano. Whole rock samples from these three localities have delta 18 O values averaging +3.9 +- 1.3, +2.4 +- 1.1, and -7.7 +- 2.4%, respectively. The observed values in the deeper samples from Krafla are as low as the values for any rocks previously reported. There seems to be a slight negative gradient in delta 18 O with depth at the former two localities and a more pronounced one at Krafla. Oxygen isotope fractionations between epidote and quartz and those between calcite and fluid suggests that the basalts were altered at temperatures of 300 0 --400 0 C. Low deltaD and delta 18 O of epidote and low delta 34 S of anhydrite indicate that the altering fluids in all three areas originated as meteoric waters and have undergone varied 'oxygen shifts'. Differences in the 18 O shift of the fluids are attributed to differences in hydrothermal systems; low water/rock ratios ( 5) at Krafla. The convective hydrothermal activity, which is probably driven by silicic magma beneath the central volcanoes, has caused strong subsolidus depletion of 18 O in the rocks. The primary-magnetic delta 18 O value of the rocks in the Tertiary IRDP core was about +3.9%, which is lower than that obtained for fresh basalt from other places. Such exceptionally low delta 18 O magmas are common in Iceland and may occur as the result of oxygen isotope exchange with or assimilation of altered rocks that form a thick sequence beneath the island due to isostatic subsidence

Ettehadian, M.; Momenzadeh, S.; Ansar, M.; Burcl, R.

2001-01-01

Full text: Normal operation of 5 MW research reactor, and radioisotope application in medicine, industry and research institutes generate a significant amount of low level radioactive waste. The volume is expected to increase with the expansion of nuclear application. This paper describes the establishing of centralized waste treatment facility developed by Atomic Energy Organization of Iran (AEOI) using IAEA technical assistance and recommendation. The new treatment facility will enable the currently produced RW to be treated conditioned and stored until a national repository becomes available. The centralized facility consists of a waste processing and storage buildings, which will be used to store conditioned waste drums. The treatment methods used for liquid wastes are precipitation, ion exchange and ultra filtration followed by In-drum cementation of residues. An In-drum compactor will be used for compaction of solid wastes. Safe management of low and intermediate radioactive waste, better protection of environment and population and applying suitable and economical processes for treatment of L/ILW are the other objectives of this activity.

Geographic Names of Iceland's Glaciers: Historic and Modern

Sigurðsson, Oddur; Williams, Richard S.

2008-01-01

Climatic changes and resulting glacier fluctuations alter landscapes. In the past, such changes were noted by local residents who often documented them in historic annals; eventually, glacier variations were recorded on maps and scientific reports. In Iceland, 10 glacier place-names are to be found in Icelandic sagas, and one of Iceland's ice caps, Snaefellsjokull, appeared on maps of Iceland published in the 16th century. In the late 17th century, the first description of eight of Iceland's glaciers was written. Therefore, Iceland distinguishes itself in having a more than 300-year history of observations by Icelanders on its glaciers. A long-term collaboration between Oddur Sigurdsson and Richard S. Williams, Jr., led to the authorship of three books on the glaciers of Iceland. Much effort has been devoted to documenting historical glacier research and related nomenclature and to physical descriptions of Icelandic glaciers by Icelanders and other scientists from as far back as the Saga Age to recent (2008) times. The first book, Icelandic Ice Mountains, was published by the Icelandic Literary Society in 2004 in cooperation with the Icelandic Glaciological Society and the International Glaciological Society. Icelandic Ice Mountains was a glacier treatise written by Sveinn Palsson in 1795 and is the first English translation of this important scientific document. Icelandic Ice Mountains includes a Preface, including a summary of the history and facsimiles of page(s) from the original manuscript, a handwritten copy, and an 1815 manuscript (without maps and drawings) by Sveinn Palsson on the same subject which he wrote for Rev. Ebenezer Henderson; an Editor's Introduction; 82 figures, including facsimiles of Sveinn Palsson's original maps and perspective drawings, maps, and photographs to illustrate the text; a comprehensive Index of Geographic Place-Names and Other Names in the treatise; References, and 415 Endnotes. Professional Paper 1746 (this book) is the second

Volcanic systems of Iceland and their magma source

Science.gov (United States)

Sigmarsson, Olgeir

2017-04-01

Several active hot-spot volcanoes produce magma from mantle sources which composition varies on decadal time scale. This is probably best demonstrated by the recent work of Pietruszka and collaborators on Kilauea, Hawaii. In marked contrast, basalt lavas from volcanic system in Iceland located above the presumed centre of the Iceland mantle plume have uniform isotope composition over the last 10 thousand years. Volcanic systems are composed of a central volcano and a fissure swarm, or a combination of both and they represent a fundamental component of the neovolcanic zones in Iceland. Four such systems, those of Askja, Bárðarbunga, Kverkfjöll and Grímsvötn in central Iceland were chosen for investigation. The last three have central volcanoes covered by the Vatnajökull ice-sheet whereas part of their fissure swarms is ice-free. Tephra produced during subglacial eruptions together with lavas from the fissure swarms of Holocene age have been collected and analysed for Sr, Nd and Th isotope ratios. Those volcanic formations that can be univocally correlated to a given volcanic system display uniform isotope ratio but different from one volcanic system to another. An exception to this regularity is that Askja products have isotope ratios indistinguishable from those of Gímsvötn, but since these volcanic systems lies far apart their lava fields do not overlap. A practical aspect of these findings was demonstrated during the rifting event of Bárðarbunga and fissure eruption forming the Holuhraun lava field. Relatively low, O isotope ratios in these basalts and heterogeneous macrocrystal composition have been ascribed to important metabasaltic crustal contamination with or without crystal mush recycling. In that case a surprisingly efficient magma mixing and melt homogenization must have occurred in the past beneath the volcanic systems. One possibility is that during the rapid deglaciation much mantle melting occurred and melts accumulated at the mantle

Nation in a sheep’s coat: The Icelandic sweater

Directory of Open Access Journals (Sweden)

Gudrun Helgadottir

2011-12-01

Full Text Available The Icelandic sweater is presented and received as being traditional—even ancient—authentically Icelandic and hand made by Icelandic women from the wool of Icelandic sheep. Even so, the sweater type, the so-called ‘Icelandic sweater’ in English, only dates back to the mid-20th century and is not necessarily made in Iceland nor from indigenous wool. Nevertheless, the sweater is a successful invention of a tradition (Hobsbawm & Ranger, 1983, popular among Icelanders and tourists alike since its introduction in the mid-20th century. It has gained ground as a national symbol, particularly in times of crisis for example in the reconstruction of values in the aftermath of the Icelandic bank collapse of 2008. I traced the development of the discourse about wool and the origins of the Icelandic sweater by looking at publications of the Icelandic National Craft Association, current design discourse in Iceland and its effect on the development of the wool industry. I then tied these factors to notions of tradition, authenticity, national culture, image and souvenirs.

Long-term variability of dust-storms in Iceland

Science.gov (United States)

Dagsson-Waldhauserová, Pavla; Ólafsson, Haraldur; Arnalds, Ólafur

2013-04-01

Iceland is a volcanic island in the North Atlantic Ocean with maritime climate. In spite of moist climate, large areas are with limited vegetation cover where >40% of Iceland is classified with considerable to very severe erosion and 21% of Iceland are volcanic sandy deserts. Natural emissions from these sources influenced by strong winds affect not only regional air quality in Iceland ("Reykjavik haze") but dust particles are transported over the Atlantic ocean and Arctic Ocean > 1000 km at times. The study places Icelandic dust production area into international perspective, present long term frequency of dust storm events in NE Iceland, and estimate dust aerosol concentrations during reported dust events. Meteorological observations with dust presence codes and related visibility were used to identify the frequency and the long-term changes in dust production in NE Iceland. There were annually 16.4 days on average with reported dust observations on weather stations within the NE erosion area, indicating extreme dust plume activity and erosion within the NE deserts, even though the area is covered with snow during the major part of winter. During the 2000s the highest occurrence of dust events in six decades was reported. We have measured saltation and aeolian transport during dust/volcanic ash storms in Iceland which give some of the most intense wind erosion events ever measured. Icelandic dust affects the ecosystems over much of Iceland and causes regional haze. It is likely to affect the ecosystems of the oceans around Iceland, and it brings dust that lowers the albedo of the Icelandic glaciers, increasing melt-off due to global warming. The study indicates that Icelandic dust is not only a substantial source for regional air pollution, but may be considered to contribute to the Arctic haze phenomena and Arctic air pollution.

Geothermal and hydropower production in Iceland

International Nuclear Information System (INIS)

Rosa, D.J.

1993-01-01

This paper analyzes the impact of current and future development of geothermal and hydropower production on the economy of Iceland. Natural conditions in Iceland favor the increased utilization and development of both of these abundant power sources. The mean surface run-off in Iceland is about 50 l/s/km 2 (liters per second per square kilometer), with a large part of the country consisting of a plateau more than 400 meters above sea level. More than half of the country is above 500 meters above sea level. ne technically harnessable hydropower potential is estimated at 64 TWh/year (terawatthours per year), of which 30 TWh/year is considered economically and environmentally harnessable. In addition, Iceland has abundant geothermal energy sources. A quarter of the entire country is a volcanic area. Keeping in mind that geothermal resources are not strictly renewable, it is estimated that the potential power production from this source is 20 TWh/year. Present utilization of these two resources totals only 4.2 TWh/year, or only about 8% of Iceland's aggregate potential. There are many issues facing Iceland today as it considers development opportunities utilizing both of these abundant power supplies. This paper will first consider the technical aspects of both hydropower and geothermal power production in Iceland. Then, the economic consequences of alternative utilization of these energy sources will be evaluated. The first alternative to be considered will be the direct export of power by HVDC submarine cable to other countries, such as Scotland or the United Kingdom. Iceland could, as a second alterative, concentrate its efforts on bringing in energy intensive industries into the country

New concepts in hydrogen production in Iceland

Arnason, B.; Sigfusson, T.I.; Jonsson, V.K.

1993-01-01

The paper presents some new concepts of hydrogen production in Iceland for domestic use and export. A brief overview of the Icelandic energy consumption and available resources is given. The cost of producing hydrogen by electrolysis is calculated for various alternatives such as plant size, load factors and electricity cost. Comparison is made between the total cost of liquid hydrogen delivered to Europe from Iceland and from Northern America, showing that liquid hydrogen delivered to Europe from Iceland would be 9% less expensive. This assumes conventional technology. New technologies are suggested in the paper and different scenarios for geothermally assisted hydrogen production and liquefaction are discussed. It is estimated that the use of geothermal steam would lead to 19% lower hydrogen gas production costs. By analysing the Icelandic fishing fleet, a very large consumer of imported fuel, it is argued that a transition of fuel technology from oil to hydrogen may be a feasible future option for Iceland and a testing ground for changing fuel technology.

2014-12-01

Geochemical sampling and data processing were implemented for prospecting Cu mineralization through catchment basin approach in central Iran, Yazd province, over drainage systems in order to determine areas of interest for the detailed exploration program. The target zone, inside an area called Kalout-e-Ashrafa in Yazd province-Iran, was characterized by the collection of 107 stream sediment samples. Catchment basin modeling was conducted based on digital elevation model (DEM) and geological map of the study area. Samples were studied by univariate and multivariate statistical techniques of exploratory data analysis, classical statistical analysis and cluster analysis. The results showed that only Cu had anomalous behavior and it did not exhibit a considerable correlation with other elements. Geochemical maps were prepared for Cu and anomalous zones and separated for potential copper mineralization. It was concluded that due to especial geomorphological and geographical characteristics (smooth topography, negligible annual precipitation and insufficient thickness of silicified Cu-bearing outcrops of the area), low concentrations of Cu would be expected for the delineation of promising zones in similar trains. Using cluster analysis showed that there was a strong correlation between Ag, Sr and S. Calcium and Pb present moderate correlation with Cu. Additionally, there was a strong correlation between Zn and Li, thereby indicating a meaningful correlation with Fe, P, Ti and Mg. Aluminum, Sc and V had a correlation with Be and K. Applying threshold value according to MAD (median absolute deviation) helped us to distinguish anomalous catchments more properly. Finally, there was a significant kind of conformity among anomalous catchment basins and silicified veins and veinlets (as validating index) at the central part of the area.

In 1956 one of the biggest blow-outs in the history of the oil industry occurred in central Iran on the Alborz structure. The well blew oil and large quantities of gas at an average rate of 60,000 bpd for 82 days for a total production in excess of 5 million bbl. The drill only nicked the reservoir, with a penetration of 2 in. Good data have been published on this event which makes this blow-out almost unique. The observations indicate that the reservoir is very highly overpressured, that the reservoir rock must have enormous permeability, and the length of the blow-out shows that rapid pressure depletion is not a problem. This indicates that Alborz is a commercial field in a high pressure environment, contrary to the widely held opinion that high pressure reservoirs are noncommercial. 10 references.

volume of landings is constituted by pelagic species. Cod, which is mainly caught in the Icelanders’ own exclusive economic zone, is the economically most important fish. The aim of this chapter is to evaluate the Icelandic individual transferable quota shares system with its management innovations, e.......g. harvest control rule for cod, cod equivalents, temporary closed areas, community quotas and features for regulation of quota concentration. The evaluation considers four possible fisheries management objectives, namely biological robustness, cost-effectiveness of management, economic efficiency......ABSTRACT: The fisheries sector is tremendously important for Iceland: the export of fish products accounts for a large part of the value of exported goods. Fisheries policy in Iceland is, consequently, of national importance to a degree that is not comparable to any of the EU member states...

2001-01-01

The purpose of this study was to assess the readiness of occupational therapists in Iceland to accept a professional as opposed to a technical view of the profession. Most Icelandic occupational therapists were educated in other countries, with little emphasis on liberal arts, sciences and research. The first Icelandic occupational therapy programme, a university-level programme, was founded in 1997. All Icelandic occupational therapists were surveyed. Eighty-seven questionnaires were sent out and 80 (92%) were returned and used for statistical analysis. The results of the study showed that Icelandic occupational therapists valued academic skills over technical skills, emphasizing occupational therapy theory unique to the profession and research to validate practice. More recognition among other health professionals was considered the most needed change in the profession. The results of the study showed that the clinicians' attitudes confirmed in general what is emphasized in the curriculum and in students' fieldwork. Further research is needed to explore whether the Icelandic occupational therapy profession succeeds in promoting research and recognition by other health professions.

Full Text Available Background: Cutaneous leishmaniasis (CL is one of the most important health problems in many areas of Iran. There are two forms of the disease in Iran, anthroponotic and zoonotic CL. This study conducted to assess the epi­demiological situation of CL in an endemic area of Qom Province, central Iran from Apr to Nov 2015.Methods: The sticky paper traps and aspirating tubes were used for collecting adult sand flies. Sherman traps and small insect nets were used to capture rodents and small mammals. Giemsa staining was used for preparing the ex­panded smear and followed by PCR for identifying the causative agent in human, vectors, and reservoirs. In this study, relative frequency of CL was also calculated.Results: Fourteen species of Phlebotomine sand flies were collected. Phlebotomus papatasi (61.74% was the pre­dominant species through the period of activity. Overall, 62 Meriones libycus, 8 Nesokia indica, 4 Mus musculus, 16 Allactaga elater and 2 Hemiechinus auritis were caught. PCR technique showed 6 out of 150 P. papatasi (2%, two out of 62 M. libycus (3.23% and all of suspected human's skin tissue samples (100% were infected with Leishmania major. The relative frequency of CL was 0.30%. Conclusion: This is the first detection of L. major within P. papatasi, M. libycus and human in Kahak District in Qom Province of Iran. Zoonotic cycle of CL exists in this area, L. major is the causative agent, P. papatasi is the main vector and M. libycus is the main reservoir of the disease. 

A simple formula for estimating global solar radiation in central arid deserts of Iran

2008-01-01

Over the last two decades, using simple radiation models has been an interesting task to estimate daily solar radiation in arid and semi-arid deserts such as those in Iran, where the number of solar observation sites is poor. In Iran, most of the models used so far, have been validated for a few specific locations based on short-term solar observations. In this work, three different radiation models (Sabbagh, Paltridge, Daneshyar) have been revised to predict the climatology of monthly average daily solar radiation on horizontal surfaces in various cities in central arid deserts of Iran. The modifications are made by the inclusion of altitude, monthly total number of dusty days and seasonal variation of Sun-Earth distance. A new height-dependent formula is proposed based on MBE, MABE, MPE and RMSE statistical analysis. It is shown that the revised Sabbagh method can be a good estimator for the prediction of global solar radiation in arid and semi-arid deserts with an average error of less than 2%, that performs a more accurate prediction than those in the previous studies. The required data for the suggested method are usually available in most meteorological sites. For the locations, where some of the input data are not reported, an alternative approach is presented.

Iceland possesses a wealth of hydro power and geothermal energy. No less than 50,000 GWh/year of power are estimated to be producible from hydro and geothermal in Iceland at a sufficiently low cost to be of interest to power-intensive industries and for export. Only a fraction of this energy potential has been developed or some 5,000 GWh/year. The power resources of Iceland represent one of the country's best opportunities for large scale development and economic growth and their utilization is high on the Government's priority list. In the past Iceland has run a successful campaign attracting foreign investors in power intensive industries and about half of the electric production today is consumed by power intensive industries. New industries can be sure of highly competitive power prices compared with Europe and North America for new contracts. Many other reasons for locating energy intensive industry in Iceland are outlined in the paper, such as the educated work-force, European culture and political stability, Mid-Atlantic location and proximity to markets, good transport and communication facilities, abundance of fresh water, good industrial sites with a large extension potential and excellent harbors for large vessels. The future prospects for hydro and geothermal energy include large greenfield aluminium smelters, direct export of electricity by submarine cables to the European continent and industries using geothermal steam for process application. The Icelandic Energy Marketing Unit, established in 1988 is mandated to promote and market Iceland's energy resources and seek investors in the field of power intensive industries. Currently marketing efforts are being undertaken to promote the direct use of geothermal steam for industrial application

Through funding from the European FP7 programme, the International Civil Aviation Authority (ICAO), as well as the local Icelandic government and RANNÍS research fund, the establishment of the Icelandic volcano observatory (VO) as a cross-disciplinary, international volcanological data node and data service is starting to materialize. At the core of this entity is the close collaboration between the Icelandic Meteorological Office (IMO), a natural hazard monitoring and research institution, and researchers at the Earth Science Institute of the University of Iceland, ensuring long-term sustainable access to research quality data and products. Existing Icelandic Earth science monitoring and research infrastructures are being prepared for integration with the European EPOS infrastructure. Because the VO is located at a Met Office, this infrastructure also includes meteorological infrastructures relevant to volcanology. Furthermore, the FP7 supersite project, FUTUREVOLC cuts across disciplines to bring together European researchers from Earth science, atmospheric science, remote sensing and space science focussed on combined processing of the different data sources and results to generate a multiparametric volcano monitoring and early warning system. Integration with atmospheric and space science is to meet the need for better estimates of the volcanic eruption source term and dispersion, which depend not only on the magma flow rate and composition, but also on atmosphere-plume interaction and dispersion. This should lead to better estimates of distribution of ash in the atmosphere. FUTUREVOLC will significantly expand the existing Icelandic EPOS infrastructure to an even more multidisciplinary volcanological infrastructure. A central and sustainable part of the project is the establishment of a research-quality data centre at the VO. This data centre will be able to serve as a volcanological data node within EPOS, making multidisciplinary data accessible to

Long-term dust aerosol production from natural sources in Iceland.

Iceland is a volcanic island in the North Atlantic Ocean with maritime climate. In spite of moist climate, large areas are with limited vegetation cover where >40% of Iceland is classified with considerable to very severe erosion and 21% of Iceland is volcanic sandy deserts. Not only do natural emissions from these sources influenced by strong winds affect regional air quality in Iceland ("Reykjavik haze"), but dust particles are transported over the Atlantic ocean and Arctic Ocean >1000 km at times. The aim of this paper is to place Icelandic dust production area into international perspective, present long-term frequency of dust storm events in northeast Iceland, and estimate dust aerosol concentrations during reported dust events. Meteorological observations with dust presence codes and related visibility were used to identify the frequency and the long-term changes in dust production in northeast Iceland. There were annually 16.4 days on average with reported dust observations on weather stations within the northeastern erosion area, indicating extreme dust plume activity and erosion within the northeastern deserts, even though the area is covered with snow during the major part of winter. During the 2000s the highest occurrence of dust events in six decades was reported. We have measured saltation and Aeolian transport during dust/volcanic ash storms in Iceland, which give some of the most intense wind erosion events ever measured. Icelandic dust affects the ecosystems over much of Iceland and causes regional haze. It is likely to affect the ecosystems of the oceans around Iceland, and it brings dust that lowers the albedo of the Icelandic glaciers, increasing melt-off due to global warming. The study indicates that Icelandic dust may contribute to the Arctic air pollution. Long-term records of meteorological dust observations from Northeast Iceland indicate the frequency of dust events from Icelandic deserts. The research involves a 60-year period and

Icelandic: A Lesser-Used Language in the Global Community

Holmarsdottir, Halla B.

2001-07-01

A small nation in the middle of the North Atlantic, Iceland currently has a population of 265,000 (1996). The Iceland language has changed very little since the island was settled some 11 centuries ago. Despite the relatively small number of people who speak the language and irrespective of the globalisation efforts by the international community, which includes the ever-increasing influence of English worldwide, the Icelandic language and culture are stronger than ever. The current volume and variety of publications of Icelandic works in all areas have never been as great. Icelandic is a living and growing language. Growth in vocabulary, in response to recent phenomena like the introduction of new technology, has primarily come about with the development of new words from the language's roots. The near absence of Latin, Greek and, more recently, English or Danish words in Icelandic, is striking. Iceland's language policy is not only a governmental policy. It is a policy that comes from the grassroots with the government and official institutions viewing their job as one of service to the people of Iceland. Icelanders are very proud of their language and are extremely determined to continually develop and preserve it for future generations.

The Cenozoic deformation history of Central Iran has been dominantly accommodated by the activation of major intracontinental strike-slip fault zones, developed in the hinterland domain of the Arabia-Eurasia convergent margin. Few quantitative temporal and kinematic constraints are available from these strike-slip deformation zones, hampering a full assessment of the style and timing of intraplate deformation in Iran and the understanding of the possible linkage to the tectonic reorganization of the Zagros collisional zone. This study focuses on the region to the north of the active trace of the sinistral Doruneh Fault. By combing structural and low-temperature apatite fission track (AFT) and (U-Th)/He (AHe) thermochronology investigations, we provide new kinematic and temporal constraints to the deformation history of Central Iran. Our results document a post-Eocene polyphase tectonic evolution dominated by dextral strike-slip tectonics, whose activity is constrained since the early Miocene in response to an early, NW-SE oriented paleo-σ1 direction. A major phase of enhanced cooling/exhumation is constrained at the Miocene/Pliocene boundary, caused by a switch of the maximum paleo-σ1 direction to N-S. When integrated into the regional scenario, these data are framed into a new tectonic reconstruction for the Miocene-Quaternary time lapse, where strike-slip deformation in the intracontinental domain of Central Iran is interpreted as guided by the reorganization of the Zagros collisional zone in the transition from an immature to a mature stage of continental collision.

Individualistic Vikings: Culture, Economics and Iceland

Full Text Available Icelandic culture has generally been considered to share many similarities to the Nordic cultures. However, the financial crisis in 2008 painted a completely different picture, with the Nordic nations faring much less worse than Iceland, which saw its banking system becoming almost entirely worthless. Looking at traditional cultural yardsticks in the vein of the most commonly used research in the field of business and organizational management, generally linked to Hofstede´s dimensional studies, one would at first glance conclude that Icelanders would have behaved in a similar manner as people in the Nordic nations. By focusing on savings ratio, it is shown that Icelanders were much more risk-seeking during the prelude of the crisis. Many nations badly hit during the 2008 financial crisis have a high level of individualism inherent in their culture. Iceland fits this scenario. Thus while general cultural characteristics may lack explanatory power regarding economic behavior of people between cultures, the individual/collective cultural dimension may provide clues of what dangers (and possible strengths lurk within societies from a financial point of view. Such developments may affect the financial stability of nations, especially those with a high level of individualism where financial liberalization with possible abuses is occurring.

Uranium deposits of Iran occur mainly in the Central Iran zone. Several uranium deposits have been discovered in this zone. The Narigan area is one of the most important uranium mineralized area in this zone. The uranium bearing sequences in this area are contained in the plutonic to volcanic rocks of Narigan which intruded to the Pre-Cambrian pyroclastics rocks. Plutonic and volcanic rocks are granite, rhyolite and volcanoclastic. Diabasic dykes have been intruded to these igneous rocks. The plutonic and volcanic rocks have been covered by Cretaceous limestones which seem to be youngest the rocks in this area. The aim of our project is to develop a regional exploration strategy for uranium in these igneous rocks. A grid-based sampling was planned following the results of the previous geochemical mapping at a scale of 1:100,000, integrated with geophysical data and alteration zones and outcrop of intrusive rocks. The following results are based on geological, and stream geochemical explorations in 1:20000 scale of this area. During this study 121 samples were collected from the stream sediments of <80 mesh for final sampling. Ten percent of the samples were used for checking laboratories errors. The samples were collected according to conventional methods from 30-40 cm depth of stream sediments. Finally, geochemical and radiometric data were combined and the results introduced 3 anomalies in the Narigan area

Should Iceland engage in policy dialogue with developing countries?

Full Text Available This article provides a brief overview of the current status of Icelandic development cooperation, bilaterally and multilaterally, and argues that it is time for Iceland to become more engaged in policy dialogue with developing countries on issues related to public sector reform and economic policy. Iceland should also in the authors view take more advantages of the extensive knowledge that Icelandic experts possess, and the experience they have gained, both in Iceland and internationally. Iceland should be more active in offering exerts in the public service, in the academia, as well as in the private sector to provide policy advise and technical assistance to developing countries that are implementing complex economic and public sector reforms. A number of those exerts have also gained considerable international experience in implementing policy reform programs. The article then discusses two cases: (i the case of Latvia where Iceland rushed to recognize its independence, but did little to assist the country in the post independence period, and (ii, the case of Vietnam where a country like Iceland could provide valuable assistance to a country that is achieving remarkable progress in poverty reduction, implementing important public sector reforms and creating a better business environment for foreign investors. This article is based on the authors experience as chairman of the Board of the Icelandic International Development Agency (ICEIDA and as Special Advisor to the Minister for Foreign Affairs in Iceland from 1995 to 1999, and as World Bank specialist at the Bank’s Head Quarters in Washington DC from 1990 to 1995, in Latvia from 1999 to 2003 and in Vietnam from 2003 to 2006.

The long-term frequency of atmospheric dust observations was investigated for the southern part of Iceland and interpreted together with earlier results obtained from northeastern (NE) Iceland (Dagsson-Waldhauserova et al., 2013). In total, over 34 dust days per year on average occurred in Iceland based on conventionally used synoptic codes for dust observations. However, frequent volcanic eruptions, with the re-suspension of volcanic materials and dust haze, increased the number of dust events fourfold (135 dust days annually). The position of the Icelandic Low determined whether dust events occurred in the NE (16.4 dust days annually) or in the southern (S) part of Iceland (about 18 dust days annually). The decade with the most frequent dust days in S Iceland was the 1960s, but the 2000s in NE Iceland. A total of 32 severe dust storms (visibility typically warm, occurring during summer/autumn (May-September) and during mild southwesterly winds, while the subarctic dust events (S Iceland) were mainly cold, occurring during winter/spring (March-May) and during strong northeasterly winds. About half of the dust events in S Iceland occurred in winter or at sub-zero temperatures. A good correlation was found between particulate matter (PM10) concentrations and visibility during dust observations at the stations Vík and Stórhöfði. This study shows that Iceland is among the dustiest areas of the world and that dust is emitted year-round.

Mesozoic to Eocene ductile deformation of western Central Iran: From Cimmerian collisional orogeny to Eocene exhumation

2012-09-01

To advance our understanding of the Mesozoic to Eocene tectonics and kinematics of basement units exposed in the south-western Central Iran plateau, this paper presents new structural and thermochronological data from the Chapedony metamorphic core complex and hangingwall units, particularly from the Posht-e-Badam complex. The overall Paleogene structural characteristics of the area are related to an oblique convergent zone. The Saghand area represents part of a deformation zone between the Arabian and Eurasian plates, and can be interpreted to result from the Central Iran intracontinental deformation acting as a weak zone during Mesozoic to Paleogene times. Field and microstructural evidence reveal that the metamorphic and igneous rocks suffered a ductile shear deformation including mylonitization at the hangingwall boundary of the Eocene Chapedony metamorphic core complex. Comparison of deformation features in the mylonites and other structural features within the footwall unit leads to the conclusion that the mylonites were formed in a subhorizontal shear zone by NE-SW stretching during Middle to Late Eocene extensional tectonics. The Chapedony metamorphic core complex is characterized by amphibolite-facies metamorphism and development of S and S-L tectonic fabrics. The Posht-e-Badam complex was deformed by two stages during Cimmerian tectonic processes forming the Paleo-Tethyan suture.

Oblique rift opening revealed by reoccurring magma injection in central Iceland

KAUST Repository

Ruch, Joel

2016-08-05

Extension deficit builds up over centuries at divergent plate boundaries and is recurrently removed during rifting events, accompanied by magma intrusions and transient metre-scale deformation. However, information on transient near-field deformation has rarely been captured, hindering progress in understanding rifting mechanisms and evolution. Here we show new evidence of oblique rift opening during a rifting event influenced by pre-existing fractures and two centuries of extension deficit accumulation. This event originated from the Bárðarbunga caldera and led to the largest basaltic eruption in Iceland in >200 years. The results show that the opening was initially accompanied by left-lateral shear that ceased with increasing opening. Our results imply that pre-existing fractures play a key role in controlling oblique rift opening at divergent plate boundaries.

Dog rose (Rosa canina L.) is a wild native species in Iran, with a significant genetic diversity. This plant serves as a rich source of vitamin C, anthocyanins, phenolic contents and carotenoids. Rose hips have been used in several food products, as well as perfumery and cosmetics industries. In this research, we investigate biochemical characteristics of five dog rose ecotypes (Kopehjamshid, Zarneh, Miyankish, Aghcheh and Sadeghiyeh), that were collected from the central part of Iran (Isfahan province). Amounts of vitamin C, total carotenoids, total phenolic contents, total anthocyanins, macro and micro minerals were measured. Seed oil are extracted by soxhlet method and analysed by gas chromatography. The macro and micro minerals levels in the fruit vary significantly among these regions. The results of this study demonstrate that dog rose have great diversity and can be used in breeding programmes in order to increase nutrient values as a food resource additive.

Re-Os dating of mineralization in Siah Kamar porphyry Mo deposit (NW Iran) and investigating on its temporal relationship with porphyry Cu-Mo deposits in the southern Lesser Caucasus, NW and central Iran

The Neo-Tethyan basin closure in Iran is characterized by the Urumieh-Dokhtar magmatic arc (UDMA), formed by north-eastward subduction of the Neo-Tethyan oceanic crust during the Alpine orogeny. This belt also coincides with the porphyry copper metallogenic belt of Iran, which hosts many porphyry Cu-Mo deposits (PCDs) and prospects, such as Sungun (NW Iran) and Sarcheshmeh (central Iran). The Siah Kamar porphyry Mo deposit (PMD) is the first discovered porphyry molybdenum deposit on this belt, which is located 10 km west of Mianeh (NW Iran), with 39.2 Mt proved reserves @ 539 ppm Mo and 66.4 Mt probable reserves @ 266 ppm Mo. The host porphyry stock has quartz-monzonitic composition, which intruded the volcanic and pyroclastic rocks of Eocene age. Re content of molybdenites is about 10.44-41.05 ppm which, considering the several tens of ppm concentration, is comparable with porphyry Mo deposits (e.g., Climax in USA), being clearly distinguished from porphyry Cu-Mo deposits. Re-Os dating of molybdenites from this PMD has given model ages between 28.1±0.15 to 29.06±0.2 Ma, and isochron age of 28.0±2.1 Ma, corresponding to the middle Oligocene (upper part of Rupelian). Comparing the ages determined for Siah Kamar PMD with porphyry Cu-Mo mineralizations in the Lesser Caucasus indicates that it is younger than most of the dated PCDs and prospects there, especially those of upper Eocene, while it is a little older than Paragachay and first-stage Kadjaran PCDs [1]. In a regional scale of NW Iran, it shows a narrow overlap with vein-type Cu-Mo-Au mineralizations in Qarachilar (Qaradagh batholith) and is nearly coeval with Haftcheshmeh PCD, indicating that mineralization in the Siah Kamar PMD corresponds to the second porphyry mineralization epoch in NW Iran, proposed by [2]. Meanwhile, mineralization in Siah Kamar is older than all the porphyry Cu-Mo mineralizations along the central and SE parts of the UDMA, except the Bondar Hanza PCD in Kerman zone, which nearly

To evaluate fatigue, sub-dimensions, and job satisfaction among workers of Iran Central Iron Ore Co., and obtain the relationship between them. In a cross-sectional study, fatigue and the dimensionality were measured using Iranian version of Piper Fatigue Scale questionnaire (PFS). Job satisfaction was estimated with the job satisfaction scale (JSS) as well. The score of severe fatigue in four sub-scale/dimensions and total fatigue scores were: 11.9, 15.2, 11.3, 10.8 and 10.6%, respectively. Furthermore, there was significant difference between total fatigue and all its sub-dimensions in relation to job satisfaction of workers. Fatigue has caused job dissatisfaction of participants in our study, therefore we should note that the nature of fatigue may affect the psychological aspects of industrial workforce and can be harmful for business activities.

[Effects of volcanic eruptions on human health in Iceland. Review].

Volcanic eruptions are common in Iceland and have caused health problems ever since the settlement of Iceland. Here we describe volcanic activity and the effects of volcanic gases and ash on human health in Iceland. Volcanic gases expelled during eruptions can be highly toxic for humans if their concentrations are high, irritating the mucus membranes of the eyes and upper respiratory tract at lower concentrations. They can also be very irritating to the skin. Volcanic ash is also irritating for the mucus membranes of the eyes and upper respiratory tract. The smalles particles of volcanic ash can reach the alveoli of the lungs. Described are four examples of volcanic eruptions that have affected the health of Icelanders. The eruption of Laki volcanic fissure in 1783-1784 is the volcanic eruption that has caused the highest mortality and had the greatest effects on the well-being of Icelanders. Despite multiple volcanic eruptions during the last decades in Iceland mortality has been low and effects on human health have been limited, although studies on longterm effects are lacking. Studies on the effects of the Eyjafjallajökul eruption in 2010 on human health showed increased physical and mental symptoms, especially in those having respiratory disorders. The Directorate of Health in Iceland and other services have responded promptly to recurrent volcanic eruptions over the last few years and given detailed instructions on how to minimize the effects on the public health. Key words: volcanic eruptions, Iceland, volcanic ash, volcanic gases, health effects, mortality. Correspondence: Gunnar Guðmundsson, ggudmund@landspitali.is.

On the relationship between Indian monsoon withdrawal and Iran's fall precipitation onset

Babaeian, Iman; Rezazadeh, Parviz

2017-09-01

Indian monsoon is the most prominent of the world's monsoon systems which primarily affects synoptic patterns of India and adjacent countries such as Iran in interaction with large-scale weather systems. In this article, the relationship between the withdrawal date of the Indian monsoon and the onset of fall precipitation in Iran has been studied. Data included annual time series of withdrawal dates of the Indian monsoon prepared by the Indian Institute for Tropical Meteorology, and time series of the first date of 25 mm accumulated precipitation over Iran's synoptic weather stations in a 10-day period which is the basis for the cultivation date. Both time series were considered in Julian calendar with the starting date on August 1. The studied period is 1960-2014 which covers 55 years of data from 36 meteorological stations in Iran. By classifying the withdrawal dates of the Indian monsoon in three stages of late, normal, and early withdrawals, its relation with the onset of fall precipitation in western, southwestern, southern, eastern, central, and northern regions of Iran was studied. Results demonstrated that in four out of the six mentioned regions, the late withdrawal of the Indian monsoon postpones the onset of fall precipitation over Iran. No significant relation was found between the onset of fall precipitation in central region of Iran and the monsoon's withdrawal date. In the western, southwestern, southern, and eastern regions of Iran, the late monsoon delays the onset of fall's precipitation; while in the south Caspian Sea coastal area, it causes the early onset of autumnal precipitation. The lag in onset of fall precipitation in Iran which is coordinated with the late withdrawal of monsoon is accompanied with prolonged subtropical high settling over Iran's plateau that prevents the southward movement of polar jet frontal systems. Such conditions enhance northerly wind currents over the Caspian Sea which, in turn, increase the precipitation in Caspian

Efficacy of glucantime for treatment of cutaneous leishmaniasis in Central Iran

Directory of Open Access Journals (Sweden)

Mahmoud Mohammadzadeh

2013-04-01

Full Text Available Summary: Glucantime remains the first-line treatment for cutaneous leishmaniasis. In a prospective study, we evaluated its efficacy and side effects in patients treated in Yazd from 2010 to 2011. Methods: Patients with lesions compatible with cutaneous leishmaniasis were considered eligible for inclusion in this study if the disease was confirmed parasitologically. The exclusion criteria were as follows: the patient preferred a treatment modality other than Glucantime; there was no indication for treatment; the patient had underlying kidney, liver, or cardiac disease; or was pregnant and lactating.Patients with ≤3 lesions and/or lesions <3 cm in diameter were treated with Glucantime intralesionally if the lesions were not located on the face, neck or joints; sporotrichoid; or superinfected with bacteria. All other patients were prescribed intramuscular Glucantime at 10–20 mg/kg/day for 20 days. Results: The failure rate for patients treated with one course of Glucantime was 22.6% overall. There were no associations between age, sex, weight, the route of administration, the number and size of lesions, the adequacy of the dose of the drug injected intramuscularly, the number of intralesional injections (<6 or ≥6 and the duration of therapy. The only factor associated with failure was reported previous exposure to antimony (p value 0.047. Adverse effects occurred in 14.2% of patients (22/155. Conclusion: Glucantime is an effective drug for the treatment of cutaneous leishmaniasis in central Iran. However, because cutaneous leishmaniasis heals spontaneously and to prevent the acquisition of resistance, the indications for treatment in each region should be defined carefully.

Aija Burdikova

2018-03-01

Full Text Available The number of immigrants living in Iceland has been steadily on the rise for the last decade; between 2007 and 2017, the percentage of immigrants living in Iceland has increased from 7.6 % to 11.9%. Akureyri, the largest town in the North of Iceland with considerable industry and service, has seen its immigrant population double in the last decade, and is now home to 931 immigrants for a total of 18 488 inhabitants. New research from the University of Akureyri[1]shows that immigrant women are the most vulnerable people in the labour market in Iceland. Many occupy positions that do not fit with their level of education; despite having received higher education than men. For example, in the survey conducted 30% of immigrant women in Akureyri answered that they are in employment that does not suit their background, compared to the same answer by only 8% of Icelandic women. This difference has a direct impact on the income: just 11% of immigrant women answered that they earn 300 000 ISK or more per month, compared to 37% for Icelandic women and 22% for immigrant men.

Genesis of iron-apatite ores in Posht-e-Badam Block (Central Iran) using REE geochemistry

Science.gov (United States)

Mokhtari, Mir Ali Asghar; Zadeh, Ghader Hossein; Emami, Mohamad Hashem

2013-06-01

Rare earth elements in apatites of different ore types show characteristic patterns which are related to different modes of formation of the ores. Most of the apatite-bearing iron ores are associated with alkaline magmas with LREE/HREE fractionation varying from moderate to steep. Iron-apatite deposits in Posht-e-Badam Block (Central Iran) have a high concentration of REE (more than 1000 ppm up to 2.5%), and show a strong LREE/HREE ratio with a pronounced negative Eu anomaly. This REE pattern is typical of magmatic apatite and quiet distinct from sedimentary apatites (phosphorites) which have a low REE contents and Ce negative anomalies. On the other hand, they are comparable to the REE patterns of apatites in Kiruna-type iron ores in different parts of the world. The REE patterns of apatites, iron-apatite ores and iron ores are similar and only have different REE contents. This similarity indicates a genetic relation for these rocks. Most of the iron-apatite deposits in Central Iran have similar REE patterns too, which in turn show a genetic relation for all of these deposits. This similarity indicates a similar origin and processes in their genesis. There are some small intrusions around some of the iron-apatite deposits that are petrographically identified as syenite and gabbro. These intrusions also have REE patterns similar to that of iron-apatite ores. This demonstrates a genetic relation between these intrusions and iron-apatite ores. The REE patterns of apatites in different deposits of Posht-e-Badam Block iron-apatite ores show an affinity to alkaline to sub-alkaline magmas and rifting environment. The alkaline host rocks of Central Iran iron-apatite ores are clearly related to an extensional setting where rifting was important (SSE-NNW fault lines). A probable source for this large scale ore forming processes is relatively low partial melting of mantle rocks. The ores have originated by magmatic differentiation as a late phase in the volcanic cycle

Assessment of relative active tectonics, south central Alborz (north Iran)

Khavari, R.; Ghorashi, M.; Arian, M.

2009-04-01

The paper present a method for evaluating relative active tectonics based on geomorphic indices useful in evaluating morphology and topography. Indices used include: stream length-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), ratio of valley-floor width to valley height (Vf), index of drainage basin shape (Bs), and index of mountain front sinuosity (Smf). Results from the analysis are accumulated and expressed as an index of relative active tectonics (Iat), which we divide into four classes from relatively low to highest tectonic activity. The study area along the south flank of the central Alborz mountain range in north Iran is an ideal location to test the concept of an index to predict relative tectonic activity on a basis of area rather than a single valley or mountain front. The recent investigations show that neotectonism has played a key role in the geomorphic evolution of this part of the Alborz mountain range. Geomorphic indices indicate the presence of differential uplifting in the geological past. The area surrounding the Amirkabir lake shows very high relative tectonic activity.

Huge natural gas reserves central to capacity work, construction plans in Iran

International Nuclear Information System (INIS)

Anon.

1994-01-01

Questions about oil production capacity in Iran tend to mask the country's huge potential as a producer of natural gas. Iran is second only to Russia in gas reserves, which National Iranian Gas Co. estimates at 20.7 trillion cu m. Among hurdles to Iran's making greater use of its rich endowment of natural gas are where and how to sell gas not used inside the country. The marketing logistics problem is common to other Middle East holders of gas reserves and a reason behind the recent proliferation of proposals for pipeline and liquefied natural gas schemes targeting Europe and India. But Iran's challenges are greater than most in the region. Political uncertainties and Islamic rules complicate long-term financing of transportation projects and raise questions about security of supply. As a result, Iran has remained mostly in the background of discussions about international trade of Middle Eastern gas. The country's huge gas reserves, strategic location, and existing transport infrastructure nevertheless give it the potential to be a major gas trader if the other issues can be resolved. The paper discusses oil capacity plans, gas development, gas injection for enhanced oil recovery, proposals for exports of gas, and gas pipeline plans

Alyson J.K. Bailes

2011-12-01

Full Text Available The concept of food security applies in both poor and rich societies and concerns the steady availability of food in the right quantity and quality, at the right price. Globally, policies to assure it remain confused and world food prices are rising. Despite large exports of fish, Iceland produces only around half of its inhabitants’ nutritional needs and relies significantly on imports, also for food production inputs like fodder and seeds. Icelandic supplies are affected by oligopoly in the retail market, and could be put at risk by events in other security dimensions ranging from natural disasters and infrastructure failures to terrorism, neighbouring conflicts and other people’s shortages. Icelandic farmers have used the terminology of ‘food security’ to press their claims for more home-grown production, and more recently also in their campaign against EU membership. The general public however shows little sign of security-awareness in this field. The government possesses suitable non-military security frameworks to address food-related risks and has initiated useful, general and specific, studies. Yet it has not developed a strategy or contingency plan for food security, even following the lessons of the 2008 economic crash and 2010-2011 eruptions. Suitable remedies would include larger emergency stocks and a range of measures to reduce vulnerability and improve resilience in crises. Above all, Iceland needs a balanced and open policy-making process to decide what its general future strategy should be as a food-producing and -importing nation. Food security could then be more precisely defined and pursued with the aim of minimizing threats and risks to that agreed vision.

The radiogenic {sup 143}Nd/{sup 144}Nd ratio of seawater is a valuable tracer of north Atlantic circulation pathways, driven by continental runoff (freshwater and Aeolian dust), boundary exchange and advection and thus mixing patterns. A region of particular interest in the North Atlantic is the overflow across the Iceland-Scotland Ridge injecting water from the Arctic Ocean into the Iceland basin (Iceland Scotland Overflow Water). However, Iceland itself constitutes a local source for Nd due to possible leaching of young volcanic basalts adding radiogenic {sup 143}Nd/{sup 144}Nd to seawater. We have conducted an intense survey of physical properties and Nd-isotope composition between Iceland and the Azores that allows to fingerprint different water masses of the North Atlantic through the {sup 143}Nd/{sup 144}Nd ratio and that demonstrates the very local influence of volcanic material to the seawater Nd cycle. A first local transect is achieved from the open ocean to the outflow of the Vatnajoekull glacier. Runoff influences seawater Nd in close vicinity (< 40 km near the outflow). A along shelf transect provide a similar observation. From Iceland to the Azores, however, water masses of the sub-tropical and sub-polar gyre are clearly distinguishable.

Recent saltmarsh foraminiferal assemblages from Iceland

Lübbers, Julia; Schönfeld, Joachim

2018-01-01

This study reports for the first time boreal to subarctic intertidal foraminiferal assemblages from saltmarshes at Borgarnes and Faskrudsfjördur on Iceland. The composition of living and dead foraminiferal assemblages was investigated along transects from the tidal flat to the highest reach of halophytic plants. The foraminiferal assemblages from Borgarnes showed 18 species in the total foraminiferal assemblage of which only 7 species were recorded in the living fauna. The assemblages were dominated by agglutinated taxa, whereas 3 calcareous species were recorded, of which only Haynesina orbicularis was found in the living fauna. The distribution limit of calcifying species corresponds to the lower boundary of the lower saltmarsh vegetation zone. Furthermore, calcareous tests showed many features of dissolution, which is an indication of a carbonate corrosive environment. The species forming the dead assemblages were mainly derived from the ambient intertidal areas and were displaced by tidal currents into the saltmarsh. The foraminiferal assemblages from Faskrudsfjördur showed two species, of which only one species was recorded in the living fauna. The assemblage was dominated by the agglutinated foraminifer Trochaminita irregularis. The foraminiferal species recorded on Iceland were the same as commonly found elsewhere in Europa. Since no species was found which is endemic to North America, Iceland is considered part of the European bio province. The foraminiferal could have been immigrated to Iceland from Europe through warm water currents, migratory birds or marine traffic since the last Ice Age.

Magmatic densities control erupted volumes in Icelandic volcanic systems

Science.gov (United States)

Hartley, Margaret; Maclennan, John

2018-04-01

Magmatic density and viscosity exert fundamental controls on the eruptibility of magmas. In this study, we investigate the extent to which magmatic physical properties control the eruptibility of magmas from Iceland's Northern Volcanic Zone (NVZ). By studying subaerial flows of known age and volume, we are able to directly relate erupted volumes to magmatic physical properties, a task that has been near-impossible when dealing with submarine samples dredged from mid-ocean ridges. We find a strong correlation between magmatic density and observed erupted volumes on the NVZ. Over 85% of the total volume of erupted material lies close to a density and viscosity minimum that corresponds to the composition of basalts at the arrival of plagioclase on the liquidus. These magmas are buoyant with respect to the Icelandic upper crust. However, a number of small-volume eruptions with densities greater than typical Icelandic upper crust are also found in Iceland's neovolcanic zones. We use a simple numerical model to demonstrate that the eruption of magmas with higher densities and viscosities is facilitated by the generation of overpressure in magma chambers in the lower crust and uppermost mantle. This conclusion is in agreement with petrological constraints on the depths of crystallisation under Iceland.

The most important properties affecting the soil loss and runoff were investigated, and the effects of land use on the soil properties, together with the erodibility indices in a semiarid zone, central Iran, were evaluated. The locations of 100 positions were acquired by cLHS and 0-5-cm surface soil layer samples were used for laboratory analyses from the Borujen Region, Chaharmahal-Va-Bakhtiari Province, central Iran. To measure in situ runoff and soil erodibility of three different land uses comprising dryland, irrigated farming, and rangeland, a portable rainfall simulator was used. The results showed that the high variations (coefficient of variation, CV) were obtained for electrical conductivity (EC), mean weight diameter (MWD), soil organic carbon (SOC), and soil erodibility indices including runoff volume, soil loss, and sediment concentration (CV ~ 43.6-77.4%). Soil erodibility indices showed positive and significant correlations with bulk density and negative correlations with SOC, MWD, clay content, and soil shear strength in the area under investigation. The values of runoff in the dryland, irrigated farming, and rangeland were found 1.5, 28.9, and 58.7 cm 3 ; soil loss in the dryland, irrigated farming, and rangeland were observed 0.25, 2.96, and 76.8 g; and the amount of sediment concentration in the dryland, irrigated farming, and rangeland were found 0.01, 0.11, and 0.15 g cm -3 . It is suggested that further investigations should be carried out on soil erodibility and the potential of sediment yield in various land uses with varying topography and soil properties in semiarid regions of Iran facing the high risk of soil loss.

Mercier, Herle; Petit, Tillys; Thierry, Virginie

2017-04-01

ISOW (Iceland Scotland Overflow Water) is the densest water in the northern Iceland Basin and a main constituent of the lower limb of the meridional overturning circulation (MOC). ISOW is the product of mixing of dense water originating from the Nordic Seas with Atlantic Water and Labrador Sea Water during its crossing of the Iceland-Faroe-Scotland Ridge and downstream acceleration. In the northern Iceland Basin, ISOW is characterized by potential density σ0 > 27.8 and salinity > 34.94. Downstream of the Iceland-Scotland Ridge, ISOW flows southwestward in a Deep Western Boundary Current along the eastern flank of the Reykjanes Ridge. Models and float trajectories previously suggested that part of the ISOW flow could cross the Reykjanes Ridge through the Bight Fracture Zone. However, no direct observations of the ISOW flow through the Bight Fracture Zone are available that would allow us to quantify its transport and water mass transformation. This lack of direct observations also prevents understanding the dynamics of the throughflow. In this study, we analyzed a set of CTDO2 and LADCP stations acquired in June-July 2015 during the Reykjanes Ridge Experiment cruise and provide new insights on the ISOW flow through the Bight Fracture Zone. The evolution of the properties as well as the velocity measurements confirm an ISOW flow from the Iceland Basin to the Irminger Sea. A main constrain to the throughflow is the presence of two sills of about 2150 m depth and two narrows. With potential densities between 27.8-27.87 kg m-3 and near bottom potential temperature of 3.02°C and salinity of 34.98, only the lightest variety of ISOW is found at the entrance of the BFZ east of the sills. In the central part of the Bight Fracture Zone, the evolution of ISOW is characterized by a decrease of 0.015 kg m-3 in the near bottom density, ascribed to the blocking of the densest ISOW variety by the sills and/or diapycnal mixing. To the West, at the exit of the BFZ, ISOW overlays

Asbjornsson, Einar Jon; Stefansson, Hlynur; Finger, David Christian

2017-04-01

The energy supply in Iceland is quite unique, about 85% of the total primary energy is coming from renewable resources. Nevertheless, the ecological footprint of an average Icelander is with 6.5 worlds, one of the highest worldwide and the energy consumption per capita is about 7 times higher than the European average. Recent developments have shown that there is a great potential to reduce the footprint and develop towards low carbon economy. With its small population, well educated and governed society and clear system boundaries to the outside world, Iceland is a good research laboratory and an ideal demonstrator for a transition towards a low carbon economy. This presentation will outline how several innovative research projects at Reykjavik University could lead Iceland towards a sustainable and low carbon economy. The presentations will conclude with a visionary outlook how Iceland can become a demonstration nation towards a prosperous, low carbon and sustainable economy, helping stabilize global warming at an acceptable level.

The Alborz mountain chain is a region of active deformation within the Arabia-Eurasia continental collision zone. The southern part of central Alborz Mountains, in the north of Iran, represents complex tectonics because it is located at the border of two developing continental sedimentary basins between southern central Alborz and Central Iran. An arid and semi-arid climate, a large extent of Quaternary sediments, rugged topography, salt domes and faults with historical seismicity influence the Habble-Rud River catchment. In the present research, a number of tectonic geomorphologic indices were extracted from satellite imagery and 10 m DEM (digital elevation model) data in order to identify relative tectonic activity within the basin. The indices include: stream length-gradient index (Sl), drainage basin asymmetry (Af), index of mountain front sinuosity (Smf), hypsometric integral (Hi), index of drainage basin shape (Bs), ratio of valley-floor width to valley height (Vf), and fault density (Fd). Due to the presence of heterogeneous indices for all sections of the catchment causing large extension of Habble-Rud (3260 km2), all of the variables such as extremely erodible formations, faults and folds and salt tectonics on the Southern part; were put into a matrix table. As a new approach, the variables were put into the SAW (simple additive model) model as one of MADM (multi-attribute decision-making models) techniques. The study area was divided into four regions according to the values of SAW. These classes include very high (%11), high (48.3%), moderate (34.7%), and low activity (3.4%). The result of the model suggests that the study area is located on a changing tectonic trend in central Alborz from NW-SE to NE-SW. The regions with high relative tectonic activity in HR catchment correspond to the active Garmsar and Sorkhe-Kalout faults and diapirs.

Erosive and Mechanical Tooth Wear in Viking Age Icelanders.

Richter, Svend; Eliasson, Sigfus Thor

(1) Background: The importance of the Icelandic Sagas as a source of information about diet habits in medieval Iceland, and possibly other Nordic countries, is obvious. Extensive tooth wear in archaeological material worldwide has revealed that the main cause of this wear is believed to have been a coarse diet. Near the volcano Hekla, 66 skeletons dated from before 1104 were excavated, and 49 skulls could be evaluated for tooth wear. The purpose of this study was to determine the main causes of tooth wear in light of diet and beverage consumption described in the Sagas; (2) Materials and methods: Two methods were used to evaluate tooth wear and seven for age estimation; (3) Results: Extensive tooth wear was seen in all of the groups, increasing with age. The first molars had the highest score, with no difference between sexes. These had all the similarities seen in wear from a coarse diet, but also presented with characteristics that are seen in erosion in modern Icelanders, through consuming excessive amounts of soft drinks. According to the Sagas, acidic whey was a daily drink and was used for the preservation of food in Iceland, until fairly recently; (4) Conclusions: It is postulated that the consumption of acidic drinks and food, in addition to a coarse and rough diet, played a significant role in the dental wear seen in ancient Icelanders.

Planetary geomorphology field studies: Iceland and Antarctica

Field studies of terrestrial landforms and the processes that shape them provide new directions to the study of planetary features. These studies, conducted in Iceland and in Antarctica, investigated physical and chemical weathering mechanisms and rates, eolitan processes, mudflow phenomena, drainage development, and catastrophic fluvial and volcanic phenomena. Continuing investigations in Iceland fall in three main catagories: (1) catastrophic floods of the Jokulsa a Fjollum, (2) lahars associated with explosive volcanic eruptions of Askja caldera, and (3) rates of eolian abrasion in cold, volcanic deserts. The ice-free valleys of Antarctica, in particular those in South Victoria Land, have much is common with the surface of Mars. In addition to providing independent support for the application of the Iceland findings to consideration of the martian erosional system, the Antarctic observations also provide analogies to other martian phenomena. For example, a family of sand dunes in Victoria Valley are stabilized by the incorporation of snow as beds.

Full Text Available Background: National Transport Commission (NTC classifies train driving as a high-level safety critical job. Objective: To assess fitness-for-work among train drivers in Yazd, central Iran. Methods: We evaluated 152 train drivers for their fitness for duty. The results were then compared with NTC guidelines. Results: 63.8% of subjects were fit for duty, 34.2% fit subject to review, and 2.0% were temporarily unfit. The most common reason for fit subject to review was a Kessler score >19. The prevalence of overweight and obesity was 48.0% and 15.0%, respectively. The prevalence of dyslipidemia was 69.7%, diabetes 10.0%, impaired fasting glucose 36.0%, and hypertension was 19.0%, respectively. Conclusion: Most studied train drivers can continue their work safely. The prevalence of some risk factors such as overweight and dyslipidemia were high among train drivers. This warrants further evaluation and establishment of control programs.

Thirteen million years of silicic magma production in Iceland: Links between petrogenesis and tectonic settings

Science.gov (United States)

Martin, E.; Sigmarsson, O.

2010-04-01

The origin of the Quaternary silicic rocks in Iceland is thought to be linked to the thermal state of the crust, which in turn depends on the regional tectonic settings. This simple model is tested here on rocks from the Miocene to present, both to suggest an internally consistent model for silicic magma formation in Iceland and to constrain the link between tectonic settings and silicic magma petrogenesis. New major and trace-element compositions together with O-, Sr- and Nd-isotope ratios have been obtained on silicic rocks from 19 volcanic systems ranging in age from 13 Ma to present. This allows us to trace the spatial and temporal evolution of both magma generation and the corresponding sources. Low δ18O (geothermal gradient. But later than 5.5 Ma they were produced in a flank zone environment by fractional crystallisation alone, probably due to decreasing geothermal gradient, of basalts derived from a mantle source with lower 143Nd/ 144Nd. This is in agreement with an eastwards rift-jump, from Snæfellsnes towards the present Reykjanes Rift Zone, between 7 and 5.5 Ma. In the South Iceland Volcanic Zone (SIVZ), the intermediate Nd-signature observed in silicic rocks from the Torfajökull central volcano reflects the transitional character of the basalts erupted at this propagating rift segment. Therefore, the abundant evolved rocks at this major silicic complex result from partial melting of the transitional alkaline basaltic crust (Iceland can, therefore, be used for deciphering past geodynamic settings characterized by rift- and off-rift zones resulting from interaction of a mantle plume and divergent plate boundaries.

Legalizing altruistic surrogacy in response to evasive travel? An Icelandic proposal

Petrologic Constraints on Iceland's Lower Crust

Science.gov (United States)

Kelley, D. F.; Leftwich, T. E.; Barton, M.

2005-05-01

Iceland is an area of relatively thick ocean crust that straddles the spreading MAR. Iceland was created by seafloor spreading originating about 55 Ma above abnormally hot mantle. The high temperatures resulted in greater melt volumes that enhanced crustal thickening. Geophysical investigations provide fundamental insight on crustal features, but results are contradictory. Early seismic, magneto-telluric, and resistivity studies predicted thin crust with partial melt regions at depths of 10-15 km beneath the neovolcanic zones. Reinterpretations based on recent seismic studies suggest thicker and cooler crust. These studies have shown magma lenses at shallow depths beneath volcanic centers, but cannot confirm their presence in the lower crust. Knowledge of the depth of magma chambers is critical to constrain the geothermal gradients in Icelandic crust and to resolve discrepancies in interpretation of geophysical data. Analyses of glasses in Icelandic lavas erupted from 11 volcanic centers throughout the rift zones have been compiled. The pressures of equilibration of these liquids with ol, high-Ca pyx, and plag were estimated qualitatively from projections into the pseudoternary system Ol-Di-Qtz. The results (ca. 0.6 GPa) indicate crystallization in magma chambers located at about 20 km depth. Equilibrium pressures also have been calculated quantitatively. These results (0.6±0.2 GPa) indicate magma chambers at 19.8±6.5 km depth beneath the volcanic centers. Magma chamber at these depths are located in the lower crust inferring that it must be relatively warm. Geothermal gradients have been calculated using the depths of the sourcing magma chambers and any shallow seismically detected magma chambers at each location. An average crustal composition has been calculated from the compiled geochemical data and was used to calculate density variations and seismic velocities along the geotherms. The distribution of sample locations in this study provides sufficient data

High resolution modelling of the North Icelandic Irminger Current (NIIC

Directory of Open Access Journals (Sweden)

K. Logemann

2006-01-01

Full Text Available The northward inflow of Atlantic Water through Denmark Strait – the North Icelandic Irminger Current (NIIC – is simulated with a numerical model of the North Atlantic and Arctic Ocean. The model uses the technique of adaptive grid refinement which allows a high spatial resolution (1 km horizontal, 10 m vertical around Iceland. The model is used to assess time and space variability of volume and heat fluxes for the years 1997–2003. Passive tracers are applied to study origin and composition of NIIC water masses. The NIIC originates from two sources: the Irminger Current, flowing as part of the sub-polar gyre in 100–500 m depth along the Reykjanes Ridge and the shallow Icelandic coastal current, flowing north-westward on the south-west Icelandic shelf. The ratio of volume flux between the deep and shallow branch is around 2:1. The NIIC continues as a warm and saline branch northward through Denmark Strait where it entrains large amounts of polar water due to the collision with the southward flowing East Greenland Current. After passing Denmark Strait, the NIIC follows the coast line eastward being an important heat source for north Icelandic waters. At least 60% of the temporal temperature variability of north Icelandic waters is caused by the NIIC. The NIIC volume and heat transport is highly variable and depends strongly on the wind field north-east of Denmark Strait. Daily means can change from 1 Sv eastward to 2 Sv westward within a few days. Highest monthly mean transport rates occur in summer when winds from north are weak, whereas the volume flux is reduced by around 50% in winter. Summer heat flux rates can be even three times higher than in winter. The simulation also shows variability on the interannual scale. In particular weak winds from north during winter 2002/2003 combined with mild weather conditions south of Iceland led to anomalous high NIIC volume (+40% and heat flux (+60% rates. In this period, simulated north Icelandic

Edible wild plant use in the Faroe Islands and Iceland

Full Text Available This paper reviews the use of wild edible plants in the Faroe Islands and Iceland from the times of the first settlement of Norse people in the Viking age until today, with a special emphasis on the 18th, 19th and 20th centuries. Animal products have been an important source of nutrients for the islanders of northern Atlantic. Cultivation of cereals on the other hand has played a minor role, and had already been abandoned by late medieval times in Iceland and by the early 20th century on the Faroes. Crops such as potatoes, turnips and other roots were only grown in the small patches of cultivated soil. Wild plants have therefore been of some importance for the Faroese people and the Icelanders; in the last centuries especially for the rural poor and during times of recessions. The native Angelica archangelica L. was gathered in the wild and also cultivated in gardens for centuries. A few species have been part of the regular food staple. Some plants are still gathered and made into food products by small companies, especially in Iceland. In the Faroes, the economic aspect of edible wild plant taxa is mostly of historical interest, although a few products of A. archangelica are sometimes available. Two taxa have been exploited as regular food exclusively in Iceland: Cetraria islandica (L. Arch. and Elymus arenarius L. Icelanders have used C. islandica from the early settlement days and continue to do so today, E. arenarius became obsolete as a food plant a century ago.

Weathering The Storm – Icelandic Municipalities’ Handling of an Unprecedented Economic Crisis

Magnús Árni Skjöld MAGNÚSSON

2016-04-01

Full Text Available Within a few days in October 2008, following serious turmoil on financial markets worldwide, some 85% of the Icelandic banking sector collapsed, together with the Icelandic currency, the króna. Almost all the rest followed early in 2009. The Icelandic stock market took a nosedive. The Republic of Iceland had entered the worst economic crisis of its history. Icelandic municipalities, which had taken on an increasing burden of running the welfare state, were hard hit financially, without the ability of the state to help out. In fact, some of the post-crisis actions of the state, under IMF direction, were difficult for the municipalities. It did not make things easier that the crisis had been precluded by an unprecedented period of growth, encouraging the municipalities to borrow in international markets and invest in infrastructure that turned out to be superfluous in the post-crisis period. This paper will look at the reactions of the Icelandic municipalities to the crisis, the political implications of it, where they are now and if there are lessons that can be learned from the difficult years in the last decade.

Full Text Available Keywords: Iron mineralization, hydrothermal vein, alteration, Lulak Abad, Zanjan, Central Iran Introduction The Lulak Abad iron occurrence is located in the northwestern part of the Central Iran, 55 km west of Zanjan. Mineralization at the Lulak Abad area was originally identified by Zamin Gostar Company (2007, during a geophysical exploration. The present paper provides an overview of the geological framework, the mineralization characteristics, and the results of a geochemical study of the Lulak Abad iron occurrence with an application to the ore genesis. Identification of these characteristics can be used as a model for exploration of this type of iron mineralization in the Central Iran and elsewhere. Materials and methods Detailed field work was carried out at different scales (give scales in parentheses in the Lulak Abad area. About 16 polished thin and thin sections from host rocks and mineralized and altered zones were studied by conventional petrographic and mineralogical methods at the Department of Geology, University of Zanjan. In addition, a total of 7 samples from ore zones at the Lulak Abad occurrence were analyzed by ICP-OES for minor and trace elements and REE compositions at Geological Survey of Iran, Tehran, Iran. Result Rock units exposed in the Lulak Abad area consist of schists and metavolcanic units the Kahar Formation; Lotfi, 2001 that were intruded by granite and microdiorite bodies. The schist units consist of chlorite-biotite-muscovite schist and muscovite schist that show granolepidoblastic texture with foliation-parallel disseminated magnetite. The metavolcanic units consist of metadacite, rhyolitic metatuff and meta-andesite with porphyritic textures. They are marked by dominant mylonitic foliation surrounding feldspar and quartz porphyroclasts. Alkali feldspar and quartz are the principal minerals of the granite. The intrusion is characterized by intense deformation features and is highly mylonitized. Based on field

2012-11-01

The aim of this study was to investigate the cadmium (Cd) and lead (Pb) content of several commercially available brands of rice grains (Oryza sativa) in central Iran. A total of 67 samples of the most widely consumed brands of rice grains were purchased from local bazaar markets in Shahrekord, Iran. The first step, grains of raw rice were digested by acid digestion method and then were analyzed by atomic absorption spectrometer. The results showed that Cd concentration in rice grains ranged from 0.0378 to 0.1225 ppm dry weight and its average concentration was 0.062 ± 0.019 ppm and Pb content ranged from 0.0405 to 0.1281 ppm dry weight and its average concentration was 0.068 ± 0.0185 ppm. Cd and Pb concentrations in the sampled rice grains were lower in comparison with their upper limits (0.2 and 0.2 ppm for Cd and Pb, respectively) approved by food sanitary standard. Therefore, it can be concluded that there is no health problems due to the consumption of brands of rice grains, for these two elements. The results indicated that weekly intake of Cd and Pb from rice grains was below the provisional tolerable weekly intakes recommended by WHO/FAO.

Full Text Available In order to study the hypercalcified sponges in reefal deposits of the Nayband Formation in Lut Block, the Garm Ab section near the village of Mehran Kushk, located about 20 km northeast of Ferdows city, was sampled. Eight horizons of reefal limestone beds are exposed in this section. The most important reef builders are hypercalcified sponges with some representatives of hexactinellids, scleractinian corals and other reef organisms. The field and lab-observations on rock units, sedimentary facies and faunal assemblages indicate the middle Norian-Rhaetian as the age of the reef horizons. Twenty-three sponge taxa, including 15 of the chambered sphinctozoans, 2 of hexactinellids sponges and 8 non-chambered inozoan were identified. The majority of recognized sponges are reported from the Nayband Formation from the other localities in central Iran. One new species identified as Cryptocoelia maxima n. sp. was recovered and is described here.

The passive of reflexive verbs in Icelandic

Directory of Open Access Journals (Sweden)

Hlíf Árnadóttir

2011-10-01

Full Text Available The Reflexive Passive in Icelandic is reminiscent of the so-called New Passive (or New Impersonal in that the oblique case of a passivized object NP is preserved. As is shown by recent surveys, however, speakers who accept the Reflexive Passive do not necessarily accept the New Passive, whereas conversely, speakers who accept the New Passive do also accept the Reflexive Passive. Based on these results we suggest that there is a hierarchy in the acceptance of passive sentences in Icelandic, termed the Passive Acceptability Hierarchy. The validity of this hierarchy is confirmed by our diachronic corpus study of open access digital library texts from Icelandic journals and newspapers dating from the 19th and 20th centuries (tímarit.is. Finally, we sketch an analysis of the Reflexive Passive, proposing that the different acceptability rates of the Reflexive and New Passives lie in the argument status of the object. Simplex reflexive pronouns are semantically dependent on the verbs which select them, and should therefore be analyzed as syntactic arguments only, and not as semantic arguments of these verbs.

Holocene and latest Pleistocene climate and glacier fluctuations in Iceland

Science.gov (United States)

Geirsdóttir, Áslaug; Miller, Gifford H.; Axford, Yarrow; Ólafsdóttir, Sædís

2009-10-01

Multiproxy climate records from Iceland document complex changes in terrestrial climate and glacier fluctuations through the Holocene, revealing some coherent patterns of change as well as significant spatial variability. Most studies on the Last Glacial Maximum and subsequent deglaciation reveal a dynamic Iceland Ice Sheet (IIS) that responded abruptly to changes in ocean currents and sea level. The IIS broke up catastrophically around 15 ka as the Polar Front migrated northward and sea level rose. Indications of regional advance or halt of the glaciers are seen in late Alleröd/early Younger Dryas time and again in PreBoreal time. Due to the apparent rise of relative sea level in Iceland during this time, most sites contain evidence for fluctuating, tidewater glacier termini occupying paleo fjords and bays. The time between the end of the Younger Dryas and the Preboreal was characterized by repeated jökulhlaups that eroded glacial deposits. By 10.3 ka, the main ice sheet was in rapid retreat across the highlands of Iceland. The Holocene thermal maximum (HTM) was reached after 8 ka with land temperatures estimated to be 3 °C higher than the 1961-1990 reference, and net precipitation similar to modern. Such temperatures imply largely ice-free conditions across Iceland in the early to mid-Holocene. Several marine and lacustrine sediment climate proxies record substantial summer temperature depression between 8.5 and 8 ka, but no moraines have been detected from that time. Termination of the HTM and onset of Neoglacial cooling took place sometime after 6 ka with increased glacier activity between 4.5 and 4.0 ka, intensifying between 3.0 and 2.5 ka. Although a distinct warming during the Medieval Warm Period is not dramatically apparent in Icelandic records, the interval from ca AD 0 to 1200 is commonly characterized by relative stability with slow rates of change. The literature most commonly describes Little Ice Age moraines (ca AD 1250-1900) as representing the

The economic success of Iceland in recent decades was the result of the development of good institutions combined with a positive global economic climate. The recent economic downturn, not just in Iceland but around the world, should be a reminder that good institutions matter and should serve as an exhortation to continue building good institutions rather than dismissing them in favor of institutions that generate poverty.

The Holuhraun fissure eruption (Bárðarbunga volcanic system, central Iceland) has been ongoing since 31 August 2014 and is now the largest in Europe since the 1783-84 Laki event. For the first time in the modern age we have the opportunity to study at first hand the environmental impact of a flood basalt fissure eruption (>1 km3 lava). Flood basalt eruptions are one of the most hazardous volcanic scenarios in Iceland and have had enormous societal and economic consequences across the northern hemisphere in the past. The Laki eruption caused the deaths of >20% of the Icelandic population by environmental pollution and famine and potentially also increased European levels of mortality through air pollution by sulphur-bearing gas and aerosol. A flood basalt eruption was included in the UK National Risk Register in 2012 as one of the highest priority risks. The gas emissions from Holuhraun have been sustained since its beginning, repeatedly causing severe air pollution in populated areas in Iceland. During 18-22 September, SO2 fluxes reached 45 kt/day, a rate of outgassing rarely observed during sustained eruptions, suggesting that the sulfur loading per kg of erupted magma exceeds both that of other recent eruptions in Iceland and perhaps also other historic basaltic eruptions globally. This raises key questions regarding the origin of these prodigious quantities of sulphur. A lack of understanding of the source of this sulfur, the conversion rates of SO2 gas into aerosol, the residence times of aerosol in the plume and the dependence of these on meteorological factors is limiting our confidence in the ability of atmospheric models to forecast gas and aerosol concentrations in the near- and far-field from Icelandic flood basalt eruptions. In 2015 our group is undertaking a project funded by UK NERC urgency scheme to investigate several aspects of the sulfur budget at Holuhraun using a novel and powerful approach involving simultaneous tracking of sulfur and

A total of 165 samples were collected from the Qom Formation investigated in a stratigraphic section north of Deh Namak, in Central Iran. From these, 35 genera and 47 species of benthic foraminifera were identified. The age of the studied section is Early Miocene (Aquitanian to Early Burdigalian) based on the occurrence of Borelis melo curdica, Meandropsina anahensis, Meandropsina iranica, Elphidium sp. 14, Peneroplis farsensis, and Triloculina tricarinata. The thickness of the Qom Formation is 401 m of which 161.2 m is early Burdigalian in age. Foraminiferal assemblages in the Deh Namak section are referable to the Borelis melo group- Meandropsina iranica Assemblage Zone and Miogypsinoides- Archaias-Valvulinid Assemblage Zone of [Adams, T.D., Bourgeois, F., 1967.

Isotope heterogeneity of Pre-Holocene groundwater in Iceland

DEFF Research Database (Denmark)

Sveinbjörnsdóttir, Á.E.; Arnorsson, S.; Heinemeier, Jan

2007-01-01

In recent years, it has been shown that groundwater with a Pre-Holocene component is more common in the Icelandic bedrock than previously thought. Some of the Pre-Holocene water samples are more depleted in delta H-2 and delta O-18 than any mean annual precipitation in Iceland today due to the cold...... climate at that time. However, most often Pre-Holocene water components cannot be detected based on the water isotopes alone due to mixing with younger and isotopically heavier water. The Cl concentration in relation to the water isotopes in specific areas has proved to be a good indicator of a Pre......-Holocene component in the groundwater. The deuterium excess value may also help to identify water from a different climate regime, if no oxygen shift has occurred. The relative abundance of a Pre-Holocene water component of the Icelandic groundwater has led to the understanding that combined interpretation of water...

Island connections: Icelandic spatiality in the wake of worldly linkages

David Bjarnason

2010-11-01

Full Text Available The notions and materiality of connections, through electronic networks as well as modes of mobility, play an ever-increasing role in how we define, understand, engage and experience the world we live in and the islands we live on. This article presents an account of Icelandic encounters with technologies of telecommunication and explores how electronic connections have participated in formulating a particularly connected, island spatiality. It is argued that an island can be regarded as a kind of connected laboratory suitable for studying how associations form around technologies of connections, which can be traced through various actors. For this purpose, the historical genealogy of connections and telecommunication in Iceland is analyzed, as well as more contemporary ideas and representations of mobile phone usage and network connectivity. It is maintained that connections have fundamentally altered the spatiality as well as representations of Iceland. While still an island in a geographical sense, and in that manner remote and isolated, the social space of the island now denies such connotations in many respects, valorizing the connectivity of Iceland and its people.

Economic conditions, hypertension, and cardiovascular disease: analysis of the Icelandic economic collapse.

Birgisdóttir, Kristín Helga; Jónsson, Stefán Hrafn; Ásgeirsdóttir, Tinna Laufey

2017-12-01

Previous research has found a positive short-term relationship between the 2008 collapse and hypertension in Icelandic males. With Iceland's economy experiencing a phase of economic recovery, an opportunity to pursue a longer-term analysis of the collapse has emerged. Using data from a nationally representative sample, fixed-effect estimations and mediation analyses were performed to explore the relationship between the Icelandic economic collapse in 2008 and the longer-term impact on hypertension and cardiovascular health. A sensitivity analysis was carried out with pooled logit models estimated as well as an alternative dependent variable. Our attrition analysis revealed that results for cardiovascular diseases were affected by attrition, but not results from estimations on the relationship between the economic crisis and hypertension. When compared to the boom year 2007, our results point to an increased probability of Icelandic women having hypertension in the year 2012, when the Icelandic economy had recovered substantially from the economic collapse in 2008. This represents a deviation from pre-crisis trends, thus suggesting a true economic-recovery impact on hypertension.

Full Text Available Researchers such as Hofstede (2002 and House, Hanges, Javidan, Dorfman and Gupta, (2004 have defined well-known cultural clusters such as, Anglo, Germanic, and Nordic cultural clusters. However, Iceland was not incorporated in these studies and therefore the research question of this paper is: In relation to Hofstede´s five cultural dimensions where does Iceland differ in relation to 25 of the OECD member states using VSM94? A questionnaire was sent to students at the University of Iceland, School of Social Sciences by e-mail in October 2013. The five dimensions of national culture were measured using scales developed by Hofstede called VSM 94. The results indicated that Iceland differs considerably from nations such as Slovakia, Japan, India, Thailand and China, which were found high in PDI and the MAS dimension while Iceland was found to be high in IDV and low in PDI. When considering the 25 OECD countries, Iceland is more similar to the Anglo cluster, C3, Canada, New Zealand, United Kingdon, Australia and United States than the Nordic cluster, C1 i.e. Denmark, Sweden and Norway. Iceland is similar to those countries in relation to high IDV, low PDI but differs in the dimensions MAS and UAI where Iceland scores higher.

Elemental and Sr, Nd, Hf and high precision Pb isotopic data are presented from 59 low-Ti and high-Ti lavas from the syn-break up part of the Faroe Flood Basalt Province. The depleted MORB-like low-Ti lavas erupted in the rift zone between the Faroe Islands and central East Greenland around......-type component similar in geochemistry to the Icelandic Öræfajökull lavas. This component is believed to be recycled pelagic sediments in the plume but it can alternatively be a local crustal or lithospheric mantle component.

Full Text Available The recent economic crisis in Iceland has raised issues of the sustainability of Icelandic higher education to new levels of importance. A key strategy in relation to this economic crisis is to consider the merger of the four public universities in Iceland and to introduce a much higher enegagement with online and open delivery methods of higher education. The Net-University Project was an EU Leonardo-funded initiative to compare approaches to open and distance education in Iceland, Sweden, and Scotland, with additional lessons from Atlantic Canada. In particular, it sought to focus on the transfer of innovation in continuing university education, with particular emphasis on the development and delivery of online higher education courses throughout rural Iceland (i.e., outside of Reykjavik. The partners concentrated on how knowledge and experience about distributed and distance learning models could be transferred between the partner countries and how such models can be integrated into the education system to better support higher education and lifelong learning. There was a particular interest in the practical use of open educational resources (OER for course design and in the sharing of these course modules among university partners. Some good practice and lessons from OER use in course creation are listed.

Cretaceous alkaline volcanism in south Marzanabad, northern central Alborz, Iran: Geochemistry and petrogenesis

Directory of Open Access Journals (Sweden)

Roghieh Doroozi

2016-11-01

Full Text Available The alkali-basalt and basaltic trachy-andesites volcanic rocks of south Marzanabad were erupted during Cretaceous in central Alborz, which is regarded as the northern part of the Alpine-Himalayan orogenic belt. Based on petrography and geochemistry, en route fractional crystallization of ascending magma was an important process in the evolution of the volcanic rocks. Geochemical characteristics imply that the south Marzanabad alkaline basaltic magma was originated from the asthenospheric mantle source, whereas the high ratios of (La/YbN and (Dy/YbN are related to the low degree of partial melting from the garnet bearing mantle source. Enrichment pattern of Nb and depletion of Rb, K and Y, are similar to the OIB pattern and intraplate alkaline magmatic rocks. The K/Nb and Zr/Nb ratios of volcanic rocks range from 62 to 588 and from 4.27 to 9 respectively, that are some higher in more evolved samples which may reflect minor crustal contamination. The isotopic ratios of Sr and Nd respectively vary from 0.70370 to 0.704387 and from 0.51266 to 0.51281 that suggest the depleted mantle as a magma source. The development of south Marzanabad volcanic rocks could be related to the presence of extensional phase, upwelling and decompressional melting of asthenospheric mantle in the rift basin which made the alkaline magmatism in Cretaceous, in northern central Alborz of Iran.

Icelandic basaltic geothermal field: A natural analog for nuclear waste isolation in basalt

International Nuclear Information System (INIS)

Ulmer, G.C.; Grandstaff, D.E.

1984-01-01

Analog studies of Icelandic geothermal fields have shown that the design of nuclear waste repositories in basalt can benefit by comparison to the data base already available from the development of these geothermal fields. A high degree of similarity exists between these two systems: their petrology, groundwater geochemistry, mineral solubilities, hydrologic parameters, temperature ranges, water-rock redox equilibria, hydrothermal pH values, and secondary mineralogies all show considerable overlap in the range of values. The experimentally-simulated hydrothermal studies of the basaltic nuclear waste repository rocks have, at this time, produced a data base that receives a strong confirmation from the Icelandic analog. Furthermore, the Icelandic analog should eventually be employed to extrapolate into higher and lower temperatures, into longer time-base chemical comparisons, and into more realistic mineral deposition studies, than have been possible in the laboratory evaluations of the nuclear waste repository designs. This eventual use of the Icelandic analog will require cooperative work with the Icelandic Geological Survey. 46 refs., 4 figs., 2 tabs

2016-12-01

Full Text Available Background: Zoonotic cutaneous leishmaniasis (ZCL is a neglected disease with public health importance that is common in many rural areas of Iran. In recent years, behavioral resistance and/or bait shyness against the common rodenticide among reservoir hosts of ZCL have been reported. The aim of this study was to evaluate the effectiveness of Klerat® and zinc phosphide against natural reservoir of ZCL.Methods: This survey was carried out in four villages located 45 to 95 km far from Esfahan City Esfahan province, central Iran from April to November 2011. The rodent burrows were counted destroyed and reopened holes baited around all villages. Effect of rodent control operation on the main vector density and incidence of ZCL were evaluated.Results: The reduction rate of rodent burrows after intervention calculated to be at 62.8% in Klerat® and 58.15% in zinc phosphide treated areas. Statistical analysis showed no difference between the densities of the vector in indoors and outdoors in intervention and control areas. The incidence of the disease between treated and control areas after intervention was statistically different (P< 0.05.Conclusion: Klerat® could be a suitable alternative for zinc phosphide in a specific condition such as behavior resistance or occurrence of bait shyness.

Imaging Subsurface Structure of Central Zagros Zone/Iran Using Ambient Noise Tomography

2017-04-01

The Central Zagros zone, of west Iran & east Iraq, is surrounded by many active faults (including Main Zagros Reversed Fault, Main Recent Fault, High Zagros Fault, Zagros Fold, & Thrust Belt). Recent studies show that cross-correlation of a long-term ambient seismic noise data recorded in station-pair, includes important information regarding empirical Green's functions (EGFs) between stations. Hence, ambient seismic noise carries valuable information of the wave propagation path (which can be extracted). The 2D model of surface waves (Rayleigh & Love) velocities for the studied area is obtained by seismic ambient noise tomography (ANT) method. Throughout this research, we use continuous records of all three vertical, radial, and tangential components (obtained by rotation) recorded by IRSC (Iranian Seismological Center) and IIEES (International Institute of Earthquake Engineering) networks for this area of interest. The IRSC & IIEES networks are equipped by SS-1 kinematics and Guralp CMG-3T sensors respectively. Data of 20 stations were used for 12 months from 2014/Nov. to 2015/Nov. The performed data processing is similar to the one, put into words in detail by Bensen et al. (2007) including the processed daily base data. Mean, trend, and instrument response were removed and the data were decimated to 5 sps (sample per second) to reduce the amount of storage space and computational time required. We then applied merge to handle data gaps. One-bit time-domain normalization was also applied to suppress the influence of instrument irregularities and earthquake signals followed by spectral (frequency-domain) normalization between 0.05-0.2 Hz (period 5-20 sec). After cross-correlation (processing step), we perform rms stacking (new approach of stacking) to stack many cross-correlation functions based on the highest energy in a time interval which we accordingly anticipate to receive Rayleigh & Love waves fundamental modes. To evaluate quality of the stacking process

Radiographic closure time of appendicular growth plates in the Icelandic horse

2007-07-01

Full Text Available Abstract Background The Icelandic horse is a pristine breed of horse which has a pure gene pool established more than a thousand years ago, and is approximately the same size as living and extinct wild breeds of horses. This study was performed to compare the length of the skeletal growth period of the "primitive" Icelandic horse relative to that reported for large horse breeds developed over the recent centuries. This information would provide practical guidance to owners and veterinarians as to when the skeleton is mature enough to commence training, and would be potentially interesting to those scientists investigating the pathogenesis of osteochondrosis. Interestingly, osteochondrosis has not been documented in the Icelandic horse. Methods The radiographic closure time of the appendicular growth plates was studied in 64 young Icelandic horses. The results were compared with previously published closure times reported for other, larger horse breeds. The radiographs were also examined for any signs of developmental orthopaedic diseases. In order to describe further the growth pattern of the Icelandic horse, the total serum alkaline phosphatase (ALP activity was determined and the height at the withers was measured. Results Most of the examined growth plates were fully closed at the age of approximately three years. The horses reached adult height at this age; however ALP activity was still mildly increased over baseline values. The growth plates in the digits were the first to close at 8.1 to 8.5 months of age, and those in the regions of the distal radius (27.4 to 32.0 months, tuber olecrani (31.5 to 32.2 months, and the stifle (27.0 to 40.1 months were the last to close. No horse was found to have osteochondrosis type lesions in the neighbouring joints of the evaluated growth plates. Conclusion The Icelandic horse appears to have similar radiographic closure times for most of the growth plates of its limbs as reported for large new breeds of

Gudmundur Finnbogason, "sympathetic understanding," and early Icelandic psychology.

Pind, Jörgen L

2008-05-01

Gudmundur Finnbogason (1873-1944) was a pioneer of Icelandic psychology. He was educated at the University of Copenhagen where he finished his M.A. in 1901 in philosophy, specializing in psychology. During the years 1901-1905, Finnbogason played a major role in establishing and shaping the future of primary education in Iceland. He defended his doctoral thesis on "sympathetic understanding" at the University of Copenhagen in 1911. This work deals with the psychology of imitation. In it Finnbogason defends the view that imitation is basically perception so that there is a direct link from perception to motor behavior. Through imitation people tend to assume the countenance and demeanor of other people, thus showing, in Finnbogason's terminology, "sympathetic understanding." Finnbogason's theory of imitation in many respects anticipates contemporary approaches to the psychology of imitation. In 1918 Finnbogason became professor of applied psychology at the recently founded University of Iceland. Here he attempted to establish psychology as an independent discipline. In this he was unsuccessful; his chair was abolished in 1924.

Shorebirds are a primary reservoir of avian influenza viruses (AIV). We conducted surveillance studies in Iceland shorebird populations for 3 years, documenting high serological evidence of AIV exposure in shorebirds, primarily in Ruddy Turnstones (Arenaria interpres; seroprevalence = 75%). However, little evidence of virus infection was found in these shorebird populations and only two turnstone AIVs (H2N7; H5N1) were able to be phylogenetically examined. These analyses showed that viruses from Iceland shorebirds were primarily derived from Eurasian lineage viruses, yet the H2 hemagglutinin gene segment was from a North American lineage previously detected in a gull from Iceland the previous year. The H5N1 virus was determined to be low pathogenic, however the PB2 gene was closely related to the PB2 from highly pathogenic H5N1 isolates from China. Multiple lines of evidence suggest that the turnstones were infected with at least one of these AIV while in Iceland and confirm Iceland as an important location where AIV from different continents interact and reassort, creating new virus genomes. Mounting data warrant continued surveillance for AIV in wild birds in the North Atlantic, including Canada, Greenland, and the northeast USA to determine the risks of new AI viruses and their intercontinental movement in this region.

Graben formation during the Bárðarbunga rifting event in central Iceland

KAUST Repository

Ruch, Joel

2015-04-01

On the 16th of August 2014, an intense seismic swarm was detected at the Bárðarbunga caldera (central Iceland), which migrated to the east and then to the northeast during the following days. The swarm, highlighting magma propagation pathway from the caldera, migrated laterally during the following two weeks over 40 km. By the end of August, a volcanic eruption had started along a north-south oriented fissure located ~45 km from the caldera. Here we focus on the near-field deformation related to the dike emplacement in the shallow crust, which generated in few days an 8 km long by 0.8 km wide graben (depression) structure. The new graben extends from the northern edge of the Vatnajökull glacier and to the north to the eruptive fissure. We analyze the temporal evolution of the graben by integrating structural mapping using multiple acquisitions of TerraSAR-X amplitude radar images, InSAR and ground-truth data with GPS and structural measurements. Pixel-offset tracking of radar amplitude images shows clearly the graben subsidence, directly above the intrusion pathway, of up to 6 meters in the satellite line-of-sight direction. We installed a GPS profile of 15 points across the graben in October 2014 and measured its depth up to 8 meters, relative to the flanks of the graben. Field structural observations show graben collapse structures that typically accompany dike intrusions, with two tilted blocks dipping toward the graben axis, bordered by two normal faults. Extensive fractures at the center of the graben and at the graben edges show a cumulative extension of ~8 meters. The formation of the graben was also accompanied by strong seismic activity locally, constraining the time frame period of the main graben formation subsidence. Our results show a rare case of a graben formation captured from space and from ground observations. Such structures are the dominant features along rift zones, however, their formation remain poorly understood. The results also provide

Distribution and differential diagnosis of Entamoeba Histolytica from Entamoeba Dispar by the PCR-RFLP method in central Iran

Entamoeba histolytica and Entamoeba dispar are two morphologically indistinguishable human protozoan parasites that are genetically distinct species. The potential invasive pathogenic Entamoeba histolytica and non-invasive parasites Entamoeba dispar can be differentiated by molecular and other methods. We used Polymer Chain Reaction (PCR) to determine the ratio of two species in a population in central Iran.Human stool samples(n=12 148) were randomly collected in Tehran and Karaj and examined for E.histolytica/E.dispar cysts with direct and formalin-ether methods.Eighty -seven (0.7%) cases were positive, of which 49 (62.8%) isolates were successfully cultured in Robison's medium. A pair of oligonucleotide primers designed from sequence data for genomic DNA coding the 30-KD surface antigen of E.histolytica/E.dipar was used to amplify a 374 base-pair (bp) fragment. The restriction fragment length polymorphism (RFLP) pattern obtained from a standard E.histolytica isolate had had two fragments (219 bp and 155bp), but the standard isolate of E. disparshowed three fragments (155, 152 and 67bp ). Differential diagonosis of 49 isolates of E. histolytica/ E. dispar from Tehran and Karaj using PCR-RFLP revealed that 46(93.9%) were E. were E. dispar while only 2(4.1%) were E. histolytica .One person (2%) had a mixed infection and showed both patterns The differential diagonosis of the potentially pathogenic parasite E.histolytica from the non-pathogenic E. dispar is of clinical and epidemiological importance. This study demonstrated E. dispar is much more prevalent than E.histolytica among the c yst passersin Tehran and Kraj in Central Iran. (author)

To examine the incidence, type, location, and severity of injuries in Icelandic elite male handball players and compare across factors like physical characteristics and playing position. Prospective cohort study. The latter part of the preseason and the competitive season of Icelandic male handball. Eleven handball teams (185 players) from the 2 highest divisions in Iceland participated in the study. Six teams (109 players) completed the study. Injuries were recorded by the players under supervision from their team physiotherapists or coaches. Coaches recorded training exposure, and match exposure was obtained from the Icelandic and European Handball Federations. The players directly recorded potential risk factors, such as age, height, weight, previous injuries, and player position. Injury incidence and injury location and number of injury days. Recorded time-loss injuries were 86, of which 53 (62%) were acute and 33 (38%) were due to overuse. The incidence of acute injuries was 15.0 injuries/1000 hours during games and 1.1 injuries/1000 hours during training sessions. No significant difference was found in injury incidence between teams, but number of injury days did differ between teams (P = 0.0006). Acute injuries were most common in knees (26%), ankles (19%), and feet/toes (17%), but overuse injuries occurred in low back/pelvic region (39%), shoulders (21%), and knees (21%). Previous knee injuries were the only potential risk factor found for knee injury. The results indicate a higher rate of overuse injuries in low back/pelvic region and shoulders than in comparable studies.

At a time when the government of Iceland is considering privatization of alcohol sales and a reduction of its governmental fees, it is timely to estimate the potential effects of this policy change. Given that the privatization of sales coupled with a tax reduction should lead to a decrease in the unit price of alcohol, one would expect the quantity consumed to increase. While it is of interest to project the impact of the proposed bill on the market for alcohol, another important consideration is the impact that increased alcohol consumption and, more specifically, probable alcohol misuse would have on other markets in Iceland. The only available study on this subject using Icelandic data yields surprising results. Tómasson et al. (Scand J Public Health 32:47-52, 2004) unexpectedly found no effect of probable alcohol abuse on sick leave. A logical next step would be to examine the effect of probable alcohol abuse on other important labor-market outcomes. Nationally representative survey data from 2002 allow for an analysis of probable misuse of alcohol and labor-supply choices. Labor-supply choices are considered with reference to possible effects of policies already in force, as well as proposed changes to current policies. Contrary to intuition, but in agreement with the previously mentioned Icelandic study, the adverse effects of probable misuse of alcohol on employment status or hours worked are not confirmed within this sample. The reasons for the results are unclear, although some suggestions are hypothesized. Currently, data to test those theories convincingly are not available.

Do body weight and gender shape the work force? The case of Iceland.

Science.gov (United States)

Asgeirsdottir, Tinna Laufey

Most studies of the relationship between body weight - as well as its corollary, beauty - and labor-market outcomes have indicated that it is a function of a gender bias, the negative relationship between excess weight or obesity and labor-market outcomes being greater for women than for men. Iceland offers an exceptional opportunity to examine this hypothesis, given that it scores relatively well on an index of gender equality comprising economic, political, educational, labor-market, and health-based criteria. Equipped with an advanced level of educational attainment, on average, women are well represented in Iceland's labor force. When it comes to women's presence in the political sphere, Iceland is out of the ordinary as well; that Icelanders were the first in the world to elect a woman to be president may suggest a relatively gender-blind assessment in the labor market. In the current study, survey data collected by Gallup Iceland in 2002 are used to examine the relationship between weight and employment within this political and social setting. Point estimates indicate that, despite apparently lesser gender discrimination in Iceland than elsewhere, the bias against excess weight and obesity remains gender-based, showing a slightly negative relationship between weight and the employment rate of women, whereas a slightly positive relationship was found for men.

Central Asia in the Iranian geopolitical imagination

Directory of Open Access Journals (Sweden)

Edward Wastnidge

2017-02-01

Full Text Available This article charts Iran’s relations with Central Asia following the break-up of the Soviet Union in 1991. This event gave Iran a new set of neighbours to the north, and this came at a time when Iran was undergoing changes in the direction of its foreign policy from radical idealistic goals, such as the export of the Islamic Revolution, to more pragmatic aims, including giving priority to its own national interests and pursuing good neighbourly relations. Since 1991, Iran has attempted to develop relations towards the Central Asian states, both bilaterally and through various regional fora. Iran’s actions have been based, in part, on a greater commitment to regionalism that has been evident in Iranian foreign policy since the early 1990s. This has focused on cultivating economic, infrastructural and cultural links with the region, rather than any form of ideological crusade, and has helped reduce Iran’s international isolation. Following a historical contextualisation and explanation of the place that the lands of Central Asia hold in the Iranian geopolitical imagination, the article explores the key concerns of Iran in the region. It will examine Iran’s position on what it perceives as being the key issues shaping its Central Asian diplomacy, namely regional economic cooperation, pipeline politics, the status of the Caspian Sea, security cooperation and cultural diplomacy. This provides a revealing case study of how Iran perceives itself as a vital player in the region, seeking to emphasise the benefits of its geostrategic location, relative stability, and increasing international role following the nuclear deal.

Midwifery in Iceland: From vocational training to university education.

Midwifery education is a foundation for health professionals' competence in providing quality healthcare for the benefit of women, their families and society. This paper describes midwifery and the development of midwifery education in Iceland. It examines policy and extensive reforms, from hospital-based vocational training in midwifery to an academic university education, and the impact on the scope of midwifery practice in Iceland. The university-based programme, with its emphasis on autonomy of the midwife, seems to have affected the context of home birth and strengthened midwives' role in primary healthcare. Education reform with a focus on evidence-based practice and midwife-led continuity of care has had limited influence within the hospital system, where the structure of care is fragmented and childbirth is under threat of increasing interventions. Research is needed on the role of education in supporting evidence-based practice, normal childbirth and reproductive health in the Icelandic context. Copyright © 2018 Elsevier Ltd.

Full Text Available Abstracts As a contributing factor to health, the trace element selenium (Se is an essential nutrient of special interest for humans and all animals. It is estimated that 0.5 to 1 billion people worldwide suffer from Se deficiency. In spite of the important role of Se, its concentrations in soil, water and essential crops have not been studied in Iran. Therefore, the main aim of the current study was to determine the Se content of soil, water, and essential crops (rice in North, wheat in Center, date, and pistachio in South of different regions of Iran. Sampling was performed in the North, South, and Central regions of Iran. In each selected area in the three regions, 17 samples of surface soil were collected; samples of water and essential crops were also collected at the same sampling points. Upon preliminary preparation of all samples, the Se concentrations were measured by ICP-OES Model Varian Vista-MPX. The amount of soil-Se was found to be in the range between 0.04 and 0.45 ppm in the studied areas; the Se content of soil in the central region of Iran was the highest compared to other regions (p

The Lower Triassic Sorkh Shale Formation of the Tabas Block, east central Iran: Succesion of a failed-rift basin at the Paleotethys margin

The Lower Triassic Sorkh Shale Formation is a dominantly red colored marginal marine succession deposited in the north-south trending Tabas Basin of east central Iran. It is correlated with the unconformity-bounded lower limestone member of the Elika Formation of the Alborz Mountains of northern Iran. The Sorkh Shale is bounded by the pre-Triassic and post-Lower Triassic interregional unconformities and consists mainly of carbonates, sandstones, and evaporites with shale being a minor constituent. Detailed facies analysis of the Sorkh Shale Formation resulted in recognition of several genetically linked peritidal facies that are grouped into restricted subtidal, carbonate tidal flat, siliciclastic tidal flat, coastal plain and continental evaporite facies associations. These were deposited in a low energy, storm-dominated inner-ramp setting with a very gentle slope that fringed the Tabas Block of east central Iran and passed northward (present-day coordinates) into deeper water facies of the Paleotethys passive margin of northern Cimmerian Continent. Numerous carbonate storm beds containing well-rounded intraclasts, ooids and bioclasts of mixed fauna are present in the Sorkh Shale Formation of the northern Tabas Basin. The constituents of the storm beds are absent in the fair weather peritidal facies of the Sorkh Shale Formation, but are present throughout the lower limestone member of the Elika Formation. The Tabas Block, a part of the Cimmerian continent in east central Iran, is a rift basin that developed during Early Ordovician-Silurian Paleotethys rifting. Facies and sequence stratigraphic analyses of the Sorkh Shale Formation has revealed additional evidence supporting the Tabas Block as a failed rift basin related to the Paleotethys passive margin. Absence of constituents of the storm beds in the fair weather peritidal facies of the Sorkh Shale Formation, presence of the constituents of the storm beds in the fair weather facies of the Elika Formation (the

Modern tablet compression was instituted in England in 1844 by William Brockedon (1787-1854). The first tablets made according to Brockedon´s procedures contained watersoluble salts and were most likely compressed without expedients. In USA a watershed occurred around 1887 when starch (amylum maydis) was introduced to disperse tablets in aqueous milieu in order to corroborate bioavailability of drugs in the almentary canal. About the same time great advances in tablet production were introduced by the British firm Burroughs Wellcome and Co. In Denmark on the other hand tablet production remained on low scale until after 1920. As Icelandic pharmacies and drug firms modelled themselves mostly upon Danish firms tablet production was first instituted in Iceland around 1930. The first tablet machines in Iceland were hand-driven. More efficent machines came after 1945. Around 1960 three sizeable tablet producers were in Iceland; now there is only one. Numbers of individual tablet species (generic and proprietary) on the market rose from less than 10 in 1913 to 500 in 1965, with wide variations in numbers in between. Tablets have not wiped out other medicinal forms for peroral use but most new peroral drugs have been marketed in the form of tablets during the last decades.

Iceland is located on the Mid-Atlantic Ridge and thereby offers a rare opportunity to study crustal movements at a divergent plate boundary. Iceland is not only characterized by the divergence of the Eurasian and North American Plates, as several active volcanoes are located on the island. Moderate size earthquakes occur in the transform zones, causing measurable crustal deformation. In 1999 the installation of a permanent network of continuous GPS stations (ISGPS) was initiated in order to observe deformation due to unrest in the Hengill volcanic system and at the Katla volcano. The ISGPS network has been enlarged over the years and consists today of more than 25 CGPS stations. Most of the stations are located along the plate boundary, where most of the active deformation takes place. Uplift due to post-glacial rebound due to the melting of the largest glacier in Europe, Vatnajökull, is also detected by the ISGPS network. This study presents results from analysis of 9 years of data from the ISGPS network, in the global reference frame PDR05, which has been evaluated by the Potsdam-Dresden-Reprocessing group with reprocessed GPS data only. We thus determine subsidence or land uplift in a global frame. The horizontal station velocities clearly show spreading across the plate boundary of about 20 mm/a. Stations in the vicinity of the glacier Vatnajökull indicate uplift in the range of 12 mm/a, while a station in the central part of Iceland shows uplift rates of about 25 mm/a. Tide gauge readings in Reykjavik and current subsidence rates observed with CGPS agree also quite well.

Iceland as the largest source of natural air pollution in the Arctic

Arctic aerosols are often attributed to the Arctic Haze and long-range transport tracers. There is, however, an important dust source in the Arctic/Sub-arctic region which should receive more attention. The largest desert in the Arctic as well as in the Europe is Iceland with > 40,000 km2 of desert areas. The mean dust suspension frequency was 135 dust days annually in 1949-2012 with decreasing numbers in 2013-2015. The annual dust deposition was calculated as 31-40 million tons yr-1 affecting the area of > 500,000 km2. Satelite MODIS pictures have revealed dust plumes traveling > 1000 km at times. The physical properties of Icelandic dust showed differences in mineralogy, geochemical compositions, shapes, sizes, and colour, compared to the crustal mineral dust. Icelandic dust is of volcanic origin, dark in colour with sharp-tipped shards and large bubbles. About 80% of the particulate matter is volcanic glass rich in heavy metals, such as iron and titanium. Suspended dust measured at the glacial dust source consisted of such high number of close-to-ultrafine particles as concentrations during active eruptions. Generally, about 50% of the suspended PM10 are submicron particles in Iceland. Contrarily, suspended grains > 2 mm were captured during severe dust storm after the 2010 Eyjafjallajokull eruption when the aeolian transport exceeded 11 t m-1 of materials and placed this storms among the most extreme wind erosion events recorded on Earth. Our reflectance measurements showed that Icelandic dust deposited on snow lowers the snow albedo and reduces the snow density as much as Black Carbon. Icelandic volcanic dust tends to act as a positive climate forcing agent, both directly and indirectly, which is different to what generally concluded for crustal dust in the 2013 IPCC report. The high frequency, severity and year-round activity of volcanic dust emissions suggest that Icelandic dust may contribute to Arctic warming.

Depths of Magma Chambers in the Icelandic Crust

There is considerable interest in the structure and thermal state of the crust in Iceland, which lies across the Mid Atlantic Ridge. However, interpretations of seismic and gravity data yield conflicting views of the nature of the lower crust. Some interpretations prefer a model in which the lower crust (15-25 km) is relatively cool and solid, whereas other interpretations, based largely on gravity data, prefer a model in which the lower crust is relatively warm and possibly partially molten. Knowledge of the depth of magma chambers is critical to constrain the geothermal gradient in Icelandic crust and to resolve discrepancies in interpretation of geophysical data. Analyses of aphyric lavas and of glasses in Icelandic lavas erupted from 11 volcanic centers have been compiled. The compositions are picritic and basaltic with SiO2 - 47 to 50 wt%, MgO - 6 to 15wt%, FeO - 8 to 14wt%, to, Na2O - 1.3 to 3.3 wt%, and K2O - 0.03-46 wt%. The pressures of equilibration of these liquids with ol, high-Ca pyx and plag were estimated qualitatively from projections into the pseudoternary system Ol-Di-Silica using methods described by Walker and coworkers and Grove and coworkers. The results (ca. 0.5 GPa) indicate crystallization in magma chambers located at about 16 km depth. Equilibration pressures were also calculated using the method described by Yang and coworkers and by a modified version of this method. Calculated pressures (0.45±0.15 GPa) indicate magma chambers located at 15±4 km depth. Equilibration pressures for Rekjanes Ridge glasses determined using the same techniques are 0.2±0.1 GPa, corresponding to depths of 7.6±3 km. The results indicate the presence of magma chambers in the deep Icelandic crust and that the latter is relatively warm. Shallower chambers (3-7 km) have been identified from seismic studies suggesting a complex magma plumbing system. The results also confirm that magma chambers beneath Iceland are located at greater depths than those beneath the

2009-01-01

Biosphere Sr isotope composition data from Iceland and Scotland suggest that terrestrially feeding birds from these two countries will have significantly different 87 Sr/ 86 Sr isotope composition in their tissues. The aim of this study is to test if these differences can be measured within the bone and feather of migratory wading birds, who feed terrestrially as juveniles, thus providing a provenance tool for these birds. The study shows that birds can be distinguished on the basis of the Sr isotope composition of their bone. The field for Icelandic birds is defined by data from juvenile common redshank (Tringa totanus) and whimbrel (Numenius phaeopus) which give 0.7056 ± 0.0012, (2σ, n = 7). The majority of Scottish birds in this study are from coastal regions and have a signature close to that of seawater of 0.7095 ± 0.0006 (2σ, n = 9). The Sr ratios in the body tissue of these two populations of all Icelandic and Scottish adult and juvenile birds analysed are significantly different (p 87 Sr/ 86 Sr values as high as 0.7194 which reflect their non-marine diet. Icelandic redshank (Tringa totanus robusta) that have flown to Scotland and returned to Iceland show the effect of the Scottish contribution to their diet with elevated values of 0.7086 ± 0.0004, (2σ, n = 6). Redshank found in Scotland that cannot be classified on the basis biometric analysis are shown to be of Icelandic origin and analysis of the primary feathers from two birds demonstrates that isotope variation between feathers could be used to track changes in diet related to the timing of individual feather growth.

Hammons, T.J.; Palmason, G.; Thorhallsson, S.

1991-01-01

The paper reviews geothermal electric power potential in Iceland which could economically be developed to supplement hydro power for the proposed HVDC Power Link to the United Kingdom, and power intensive industries in Iceland, which are envisaged for development at this time. Technically harnessable energy for electricity generation taking account of geothermal resources down to an assumed base depth, temperature distribution in the crust, probable geothermal recovery factor, and accessibility of the field, has been assessed. Nineteen known high-temperature fields and 9 probable fields have been identified. Technically harnessable geo-heat for various areas is indicated. Data on high temperature fields suitable for geothermal electric power generation, and on harnessable energy for electric power generation within volcanic zones, is stated, and overall assessments are made. The paper then reviews how the potential might be developed, discussing preference of possible sites, and cost of the developments at todays prices. Cost of geothermal electric power generation with comparative costs for hydro generation are given. Possible transmission system developments to feed the power to the proposed HVDC Link converter stations are also discussed

The Bideghan area is located south of the Qom province (central of Iran). The most impressive geological features in the studied area are the Eocene sequences which are intruded by volcanic rocks with basic compositions. Advanced Space borne Thermal Emission and Reflection Radiometer (ASTER) image processing have been used for hydrothermal alteration mapping and lineaments identification in the investigated area. In this research false color composite, band ratio, Principal Component Analysis (PCA), Least Square Fit (LS-Fit) and Spectral Angel Mapping (SAM) techniques were applied on ASTER data and argillic, phyllic, Iron oxide and propylitic alteration zones were separated. Lineaments were identified by aid of false color composite, high pass filters and hill-shade DEM techniques. The results of this study demonstrate the usefulness of remote sensing method and ASTER multi-spectral data for alteration and lineament mapping. Finally, the results were confirmed by field investigation.

2011-06-01

The aim of the present study was to compare digestibility and metabolic response in Icelandic and Standardbred horses fed two grass haylages harvested at different stages of maturity. Six horses of each breed were used in a 24-day change-over design. A total collection of faeces was made on days 15-17 and 22-24. Blood samples were collected on day 24 of each period and analysed for total plasma protein (TPP), plasma urea, non-esterified fatty acids, cortisol and insulin concentration. There were no differences in digestibility coefficients of crude protein, neutral detergent fibre or energy between breeds but organic matter digestibility was higher in the Standardbred horses. On both haylages, the Icelandic horses gained weight whereas the Standardbred horses lost weight. The Icelandic horses had higher TPP, plasma insulin and lower plasma urea concentrations. Our results indicate that the Icelandic horse may be more prone to maintain positive energy balance in relation to the Standardbred horse, but there were no indication of a better digestive capacity in the Icelandic horses. © 2010 Blackwell Verlag GmbH.

Legalizing altruistic surrogacy in response to evasive travel? An Icelandic proposal.

Science.gov (United States)

Kristinsson, Sigurður

2016-12-01

Surrogate motherhood has been prohibited by Icelandic law since 1996, but in recent years, Icelandic couples have sought transnational surrogacy in India and the United States despite uncertainties about legal parental status as they return to Iceland with infants born to surrogate mothers. This reflects global trends of increased reproductive tourism, which forces restrictive regimes not only to make decisions concerning the citizenship and parentage of children born to surrogate mothers abroad, but also to confront difficult moral issues concerning surrogacy, global justice, human rights and exploitation. In March 2015, a legislative proposal permitting altruistic surrogacy, subject to strict regulation and oversight, and prohibiting the solicitation of commercial surrogacy abroad, was presented in the Icelandic Parliament. The proposal aims to protect the interest of the child first, respect the autonomy of the surrogate second, and accommodate the intended parents' wishes third. After a brief overview of the development of the surrogacy issue in Iceland, this article describes the main features of this legislative proposal and evaluates it from an ethical and global justice perspective. It concludes that the proposed legislation is a response to problems generated by cross-border surrogacy in the context of evolving public attitudes toward the issue, and constitutes a valid attempt to reduce the moral hazards of surrogacy consistent with insights from current bioethical literature. Although the proposed legislation arguably represents an improvement over the current ban, however, difficult problems concerning evasive travel and global injustice are likely to persist until effective international coordination is achieved.

Background The aim was to study the gastro-intestinal helminths of stray dogs of Garmsar, Semnan Province, Central Iran, and its impacts on human health and animal production. Methods During 2006, the alimentary tracts of 50 stray dogs at necropsy, selected from villages around Garmsar, were removed, and examined for helminth infections. Subsequently helminths were collected from the contents of each part and scraped sample of small intestines of washed materials in a 100-mesh sieve. To identify the species of helminths, the nematodes were cleared in lactophenol and cestodes were stained using carmine acid. Results Mixed infection was the rule and 40 dogs (80%) harbored more than one species of helminth. Taenia hydatigena was the most prevalent species (80%) followed by Echinococcus granulosus (64%), Toxocara canis (22%), Mesocestoides lineatus (12%), Taenia multiceps (10%) and Dipylidium caninum (4%). The mean intensity of worm infection was low (1–3) except for that of E. granulosus (645). No significant difference was noticed between sex, age and most helminth infections except for that of sex and T. hydatigena (P=0.001) as well as age and T. canis (P=0.001). Conclusion Although human infection with T. hydatigena is unlikely, but other helminths reported in this study are of zoonotic importance, and may pose a threat to community health, and reduce the productions of ruminants harboring taeniid metacestodes.

Reconciling biodiversity conservation and agricultural expansion in the subarctic environment of Iceland

Directory of Open Access Journals (Sweden)

Lilja Jóhannesdóttir

2017-03-01

Full Text Available Intensified agricultural practices have driven biodiversity loss throughout the world, and although many actions aimed at halting and reversing these declines have been developed, their effectiveness depends greatly on the willingness of stakeholders to take part in conservation management. Knowledge of the willingness and capacity of landowners to engage with conservation can therefore be key to designing successful management strategies in agricultural land. In Iceland, agriculture is currently at a relatively low intensity but is very likely to expand in the near future. At the same time, Iceland supports internationally important breeding populations of many ground-nesting birds that could be seriously impacted by further expansion of agricultural activities. To understand the views of Icelandic farmers toward bird conservation, given the current potential for agricultural expansion, 62 farms across Iceland were visited and farmers were interviewed, using a structured questionnaire survey in which respondents indicated of a series of future actions. Most farmers intend to increase the area of cultivated land in the near future, and despite considering having rich birdlife on their land to be very important, most also report they are unlikely to specifically consider bird conservation in their management, even if financial compensation were available. However, as no agri-environment schemes are currently in place in Iceland, this concept is highly unfamiliar to Icelandic farmers. Nearly all respondents were unwilling, and thought it would be impossible, to delay harvest, but many were willing to consider sparing important patches of land and/or maintaining existing pools within fields (a key habitat feature for breeding waders. Farmers' views on the importance of having rich birdlife on their land and their willingness to participate in bird conservation provide a potential platform for the codesign of conservation management with landowners

In Iceland the government must give permission for the building of a power station etc. but in practise the power plant administrators determine the tariffs. The structure of electric power supply mirrors a strong engagement on the part of the state and the local authorities. Almost all the power plants and distribution systems are state owned or owned by both the state and the local authorities, and so constitute a monopoly, producing 93% of the total amount of electricity supply. Government policy in this field, the Icelandic electric power distribution system and the setting of electricity prices are briefly described. It is claimed that there would be economical advantages in restructuring the distribution network and that the government favours an increase in possibilities for competition and making legislative changes. This will mean that in the future the market will play a more important role and that power plant administrators must review their duties regarding consumer satisfaction, tariffs etc. (AB)

As a consequence of the increasing aluminum production in Iceland, local processing of aluminum skimmings has become a feasible business opportunity. A recycling plant for this purpose was built in Helguvik on the Reykjanes peninsula in 2003. The case of the recycling plant reflects increased concern regarding environmental aspects of the industry. An interesting characteristic of this plant is the fact that it is run in the same facilities as a large fishmeal production installation. It is operated by the same personnel and uses—partly—the same equipment and infrastructure. This paper reviews the grounds for these decisions and the experience of this merger of a traditional fish melting industry and a more recent aluminum melting industry after 6 years of operation. The paper is written by the original entrepreneurs behind the company, who provide observations on how the aluminum industry in Iceland has evolved since the starting of Alur’s operation and what might be expected in the near future.

Background: The aim of the present study was to appraisal the prose and cone of Shiraz City in terms of its potential in the context of health tourism. Methods: The statistical sample included medical and health tourism sector in the city of Shiraz in the northwest of Fars Province, south of Iran. The efficient authorities on the topic were identified through the hospitals engaging in medical tourism. The research was based on theoretical sampling through which the experienced people of extensive knowledge on medical tourism were interviewed. Results: Active hospitals on attraction foreign patients averagely admit 15 and 50 foreign patients monthly and annually, respectively. Arab countries in the Persian Gulf were detected as the main marketing for Shiraz medical tourism. Oman encompassed the highest rate with 20% of admitted patients. Eye treatments with 30% and orthopedic with 6% were demonstrated as the highest and lowest rates in terms of foreign patients’ needs, respectively. Closeness of cultural and religious beliefs and familial relationships on one hand and trusting to Iranian physicians on the other hand were amongst the most reasons for selecting Iran as a destination for medical tourism by patients. Conclusion: Implementing 4 strategies on monitoring medical tourism would result into significant improvement of attracting more foreigner patients not only into Shiraz but all around Iran.

New results on black carbon (BC) and organic carbon (OC) on snow and ice in Iceland in 2016 will be presented in connection to our earlier results on BC and OC on Arctic seasonal snow surface, and in connection to our 2013 and 2016 experiments on effects of light absorbing impurities, including Icelandic dust, on snow albedo, melt and density. Our sampling included the glacier Solheimajökull in Iceland. The mass balance of this glacier is negative and it has been shrinking during the last 20 years by 900 meters from its southwestern corner. Icelandic snow and ice samples were not expected to contain high concentrations of BC, as power generation with domestic renewable water and geothermal power energy sources cover 80 % of the total energy consumption in Iceland. Our BC results on filters analyzed with a Thermal/Optical Carbon Aerosol Analyzer (OC/EC) confirm this assumption. Other potential soot sources in Iceland include agricultural burning, industry (aluminum and ferroalloy production and fishing industry), open burning, residential heating and transport (shipping, road traffic, aviation). On the contrary to low BC, we have found high concentrations of organic carbon in our Iceland 2016 samples. Some of the possible reasons for those will be discussed in this presentation. Earlier, we have measured and reported unexpectedly low snow albedo values of Arctic seasonally melting snow in Sodankylä, north of Arctic Circle. Our low albedo results of melting snow have been confirmed by three independent data sets. We have explained these low values to be due to: (i) large snow grain sizes up to 3 mm in diameter (seasonally melting snow); (ii) meltwater surrounding the grains and increasing the effective grain size; (iii) absorption caused by impurities in the snow, with concentration of elemental carbon (black carbon) in snow of 87 ppb, and organic carbon 2894 ppb. The high concentrations of carbon were due to air masses originating from the Kola Peninsula, Russia

The IDDP represents a challenging step forward in the worldwide development of geothermal energy by assessing the potential of power production from natural supercritical fluids. A feasibility study in 2003 concluded that in order to reach fluids at temperatures of >400°C drilling to depths of 4 to 5 km is necessary, but the resultant superheated steam should have a power output ten times that of conventional subcritical steam with the same volumetric flow rate. A consortium of leading Icelandic energy companies together with a government agency, the Icelandic Energy Authority, is carrying out the IDDP. In late 2003 a member of the consortium offered a planned exploratory well to the IDDP for deepening. This is in a geothermal system that produces hydrothermally modified seawater on the Reykjanes peninsula, in southern Iceland, where the Mid-Atlantic Ridge comes on land. Processes at depth at Reykjanes should be similar to those responsible for black smokers on ocean spreading centers. This well reached 3.1 km in February 2005, and research on the downhole samples began. Unfortunately the well became plugged during a flow test and was abandoned in February 2006 after attempts to recondition it failed. This led to the IDDP deciding to move the site for the first deep borehole to Krafla, near the northern end of the central rift zone of Iceland, within a volcanic caldera that has had recent volcanic activity. The Krafla geothermal system has higher temperature gradients than at Reykjanes but produces hydrothermally modified meteoric water with magmatic gases. The drill site chosen is near an existing well that encountered 340°C at only 2.5 km depth. It will be rotary drilled with spot coring to 3.5 km depth, and then deepened to ~4.5 km, using continuous wireline coring for scientific purposes. However, given the competition for drilling rigs internationally, and the year-long lead times in obtaining specialized well casings, it will be a year before IDDP begins

Foraminiferal-based paleobiogeographic reconstructions in the Carboniferous of Iran and its implications for the Neo-Tethys opening time: a synthesis

Arefifard, S.

2017-01-01

The biogeographic distribution of foraminifers and their belonging to either the southern or northern margins of the Paleo-Tethys are used here for paleogeographic reconstructions of Iran during the Carboniferous. Lower Carboniferous foraminiferal assemblages from northern and central Iran show a cosmopolitan character and affinities to both the southern and northern borders of the Paleo-Tethys. Hence, in the Early Carboniferous Iran occupied an intermediate southern latitude position, forming part of Gondwana. This conclusion is consistent with the Late Ordovician to Early Carboniferous drift history of Iran based on paleomagnetic data. In the Late Carboniferous, the foraminiferal affinities of northern and central Iran with the northern part of Paleo-Tethys suggest that Iran separated from Gondwana and moved northwards to a lower latitude. This separation is also evidenced by the Upper Carboniferous coal-bearing sandstones of the Sardar Formation and sandstones with high degree of chemical weathering, which would indicate warm and humid conditions. Considering the composition of foraminiferal fauna along with the evidence of magmatic activities in northwest Iran, it can be inferred that the commencement of the Neo-Tethys opening and continental break-up in Iran occurred sometime in the Late Carboniferous, which contradicts the previous claims that the separation of Iran from Gondwana occurred in Permian and/or Triassic times.

In the past 5 years the Icelandic Medical Journal has undergone many changes during a period of flourishing research in Iceland. The process of reviewing and editing scientific articles has been revised since the Journal joined the Medline database in 2005 and the proportion of rejected articles has risen. New columns have been launched covering medical history, professionalism, ethics and hobbies of the medical profession. We categorized all scientific articles from the period 2004-2008, that is research articles, review articles, case reports and clinical guidelines, according to types of articles and to which medical speciality or subspeciality the publication should belong. The number of scientific articles rose during the period but the number of research articles remained around 20 most years during the period. The relative proportion of research articles therefore fell whereas the number and proportion of review articles and case reports increased. Clinical guidelines ceased to appear in the Journal. The contribution of individual specialities to the Journal varied widely. Researchers amongst doctors and related professions need be encouraged to submit scientific articles to the Journal. The publication of scientific articles in English in the web-based form of the Journal may prove to be stimulating in this regard for Icelandic doctors abroad as well as for some researchers in Iceland.

Full Text Available The highlands and mountains of Iceland are one of the largest remaining wilderness areas in Europe. This study aimed to provide comprehensive and up-to-date data on non-native plant species in these areas and to answer the following questions: (1 How many non-native vascular plant species inhabit highland and mountainous environments in Iceland? (2 Do temporal trends in the immigration of alien species to Iceland differ between highland and lowland areas? (3 Does the incidence of alien species in the disturbed and undisturbed areas within Icelandic highlands differ? (4 Does the spread of non-native species in Iceland proceed from lowlands to highlands? and (5 Can we detect hot-spots in the distribution of non-native taxa within the highlands? Overall, 16 non-native vascular plant species were detected, including 11 casuals and 5 naturalized taxa (1 invasive. Results showed that temporal trends in alien species immigration to highland and lowland areas are similar, but it is clear that the process of colonization of highland areas is still in its initial phase. Non-native plants tended to occur close to man-made infrastructure and buildings including huts, shelters, roads etc. Analysis of spatio-temporal patterns showed that the spread within highland areas is a second step in non-native plant colonization in Iceland. Several statically significant hot spots of alien plant occurrences were identified using the Getis-Ord Gi* statistic and these were linked to human disturbance. This research suggests that human-mediated dispersal is the main driving force increasing the risk of invasion in Iceland’s highlands and mountain areas.

Superhot Drilling in Iceland, the Experience of the Iceland Deep Drilling Project.

The Iceland Deep Drilling Project aims to improve geothermal economics by producing supercritical fluids (www.iddp.is). Supercritical wells could yield an order of magnitude more usable energy than that from conventional geothermal wells because of higher enthalpy and enhanced flow properties. In 2009, the IDDP-1 well failed to reach supercritical conditions in the Krafla caldera in NE Iceland, after encountering rhyolite magma at only 2.1 km depth. The completed geothermal well became the world's hottest and produced superheated steam with a wellhead temperature of 452°C and flow sufficient to generate 35 MWe. The IDDP next moved SW to the Reykjanes Peninsula, the landward extension of the Mid-Atlantic Ridge, where it is possible to study an analog of the roots of a black smoker. Reykjanes is unique among Icelandic geothermal systems in being recharged by seawater, which has a critical point of 406°C at 298 bars. Drilling began by deepening an existing 2.5 km deep production well to 3 km depth, and then angling it towards the main upflow zone of the system, for a total slant depth of 4,659 m. Total circulation losses were encountered below 3 km that could not be cured by lost circulation materials or by multiple cement jobs. Accordingly, drilling continued to total depth without return of drill cuttings. We attempted 13 core runs below 3 km depth, only half of which recovered core. The cores are basalts and dolerites with alteration ranging from lower greenschist facies to lower amphibolite facies, suggesting formation temperatures >450°C. After the end of drilling in January 2017, following only six days of heating, supercritical conditions (426°C at 340 bars) were measured in the well at a depth of 4.5 km. The well has not yet been allowed to equilibrate to full in situ temperature. A perforated liner was inserted to 4,570 m, depth to facilitate temperature cycling to enhance permeability at depth through thermal cracking. In 2018 this will be followed by a

Macroseismic intensity attenuation in Iran

Macroseismic intensity data plays an important role in the process of seismic hazard analysis as well in developing of reliable earthquake loss models. This paper presents a physical-based model to predict macroseismic intensity attenuation based on 560 intensity data obtained in Iran in the time period 1975-2013. The geometric spreading and energy absorption of seismic waves have been considered in the proposed model. The proposed easy to implement relation describes the intensity simply as a function of moment magnitude, source to site distance and focal depth. The prediction capability of the proposed model is assessed by means of residuals analysis. Prediction results have been compared with those of other intensity prediction models for Italy, Turkey, Iran and central Asia. The results indicate the higher attenuation rate for the study area in distances less than 70km.

Heat flow and geothermal processes in Iceland

Flóvenz, Ólafur G.; Saemundsson, Kristján

1993-09-01

Heat flow values, derived from temperature measurements in shallow boreholes in Iceland, vary substantially across the country. The near-surface temperature gradients range from almost 0 to 500°C/km. The thermal conductivity of water-saturated rocks varies from 1.6 to 2.0 W/m°C. The temperature gradient in Iceland is mainly dependent on four factors: (1) the regional heat flow through the crust, (2) hydrothermal activity, (3) the permeability of the rock, and (4) residual heat in extinct volcanic centers. As Iceland is mainly made of basaltic material the radiogenic heat production is almost negligible. The thermal conductivity is, on the other hand, mainly influenced by the porosity of the rock; it increases as the porosity decreases. Iceland is made of sequences of flood basalts that formed within the volcanic rift zone—a continuation of the axis of the Mid-Atlantic ridge—and subsequently drifted sideways. Fresh basaltic lava is usually highly porous (30%) and fractured, and heat is mainly transported by convection. Therefore, a very low or even no temperature gradient is observed at shallow levels within the volcanic rift zone. As the basalt becomes buried the pores close due to lithostatic pressure and formation of secondary minerals. Below 500-1000 m depth in an uneroded lava pile, the heat is mainly transported by conduction. In the lowlands and valleys of Iceland outside the volcanic rift zone, 1000-1500 m of the original lava pile has been eroded, leaving thermal conduction as the most important heat transport mechanism. The regional temperature gradient has been measured in drillholes in dense and poorly permeable rocks away from the geothermal fields. The results show that the temperature gradient varies from 50 to 150°C/km. The highest values are found close to the volcanic rift zone and the gradient decreases with distance from the spreading axis. This result is mainly based on numerous shallow boreholes (60-500 m) but in some cases the results

The impact of divergence time on the nature of population structure: an example from Iceland.

Full Text Available The Icelandic population has been sampled in many disease association studies, providing a strong motivation to understand the structure of this population and its ramifications for disease gene mapping. Previous work using 40 microsatellites showed that the Icelandic population is relatively homogeneous, but exhibits subtle population structure that can bias disease association statistics. Here, we show that regional geographic ancestries of individuals from Iceland can be distinguished using 292,289 autosomal single-nucleotide polymorphisms (SNPs. We further show that subpopulation differences are due to genetic drift since the settlement of Iceland 1100 years ago, and not to varying contributions from different ancestral populations. A consequence of the recent origin of Icelandic population structure is that allele frequency differences follow a null distribution devoid of outliers, so that the risk of false positive associations due to stratification is minimal. Our results highlight an important distinction between population differences attributable to recent drift and those arising from more ancient divergence, which has implications both for association studies and for efforts to detect natural selection using population differentiation.

Full Text Available Background: The aim was to study the gastro-intestinal helminths of stray dogs of Garmsar, Sem­nan Province, Central Iran, and its impacts on human health and animal production.Methods: During 2006, the alimentary tracts of 50 stray dogs at necropsy, selected from villages around Garmsar, were removed, and examined for helminth infections. Subsequently helminths were collected from the contents of each part and scraped sample of small intestines of washed materials in a 100-mesh sieve. To identify the species of helminths, the nematodes were cleared in lactophenol and cestodes were stained using carmine acid.Results: Mixed infection was the rule and 40 dogs (80% harbored more than one species of helminth. Taenia hydatigena was the most prevalent species (80% followed by Echinococcus granulosus (64%, Toxocara canis (22%, Mesocestoides lineatus (12%, Taenia multiceps (10% and Dipylidium caninum (4%. The mean intensity of worm infection was low (1-3 ex­cept for that of E. granulosus (645. No significant difference was noticed between sex, age and most helminth infections except for that of sex and T. hydatigena (P=0.001 as well as age and T. canis (P=0.001.Conclusion: Although human infection with T. hydatigena is unlikely, but other helminths re­ported in this study are of zoonotic importance, and may pose a threat to community health, and reduce the productions of ruminants harboring taeniid metacestodes.

High Proportions of Sub-micron Particulate Matter in Icelandic Dust Storms in 2015

Iceland is extremely active dust region and desert areas of over 44,000 km2 acknowledge Iceland as the largest Arctic and European desert. Frequent dust events, up to 135 dust days annually, transport dust particles far distances towards the Arctic and Europe. Satellite MODIS pictures have revealed dust plumes exceeding 1,000 km. The annual dust deposition was calculated as 40.1 million tons yr-1. Two dust storms were measured in transverse horizontal profile about 90 km far from different dust sources in southwestern Iceland in the summer of 2015. Aerosol monitor DustTrak DRX 8533EP was used to measure PM mass concentrations corresponding to PM1, PM2.5, PM4, PM10 and the total PM15 at several places within the dust plume. Images from camera network operated by the Icelandic Road and Coastal Administration were used to estimate the visibility and spatial extent of measured dust events. A numerical simulation of surface winds was carried out with the numerical model HIRLAM with horizontal resolution of 5 km and used to calculate the total dust flux from the sources. The in situ measurements inside the dust plumes showed that aeolian dust can be very fine. The study highlights that suspended volcanic dust in Iceland causes air pollution with extremely high PM1 concentrations comparable to the polluted urban stations in Europe or Asia rather than reported dust event observations from around the world. The PM1/PM2.5 ratios are generally low during dust storms outside of Iceland, much lower than > 0.9 and PM1/PM10 ratios of 0.34-0.63 found in our study. It shows that Icelandic volcanic dust consists of higher proportion of submicron particles compared to crustal dust. The submicron particles are predicted to travel long distances. Moreover, such submicron particles pose considerable health risk because of high potential for entering the lungs. Icelandic volcanic glass has often fine pipe-vesicular structures known from asbestos and high content of heavy metals. Previous

The Impact of Amalgamations on Services in Icelandic Municipalities

Directory of Open Access Journals (Sweden)

Grétar Thór Eythórsson

2018-03-01

Full Text Available This article deals with answering the question whether municipal amalgamations can meet the wishes at the root of the most common motives behind them: to gain cost-efficiency and more quality in the municipal services. The analysis is partly based on a survey among Icelandic local leaders in 2015 and partly on survey among citizens in 8 recently amalgamated municipalities collected with a snowball method through Facebook in the spring and summer 2013. The main results are that the impact of amalgamations on municipal services seems to depend on whether we look at the central or peripheral parts of the municipality. Both leaders and citizens seem to perceive developments of services differently depending on the position in the municipality. In the peripheries, they have significantly more negative view than in the service centres. This has to do with both their evaluation of specific services and their general evaluation of service development. However, in the general evaluation the difference is significantly larger.

Iceland as a western country. How to classify medieval church law in the vernacular

Directory of Open Access Journals (Sweden)

Lára Magnúsardóttir

2015-12-01

Full Text Available Iceland’s subjection to the king of Norway in 1262-64 was followed by a legislation in which a law book for Church and spiritual matters was composed in the vernacular for each country. Such law was implemented in Iceland in 1275 along with a separate secular law book in 1281. Both books remained in force until the middle of the 16th century. A church law that was separate, both from the secular law and that of Roman Church appears to set Iceland apart from other Western European countries where spiritual matters were governed according to the Latin law of the Roman Church. This has been viewed as an indication of constant rivalry between the religious and secular authorities, usually presenting the Church as an overreaching and even oppressive institution against which laity struggled. But a comparison of Icelandic Church law with the Latin Canon law shows that the Church in Iceland submitted entirely to the authority of the Roman Church and thus shows that the Icelandic Church law was, despite its obscure language, a specific representation of the law of the Roman Church. A Norwegian concordat from 1277 shows the king’s recognition of separate spiritual and temporal jurisdictions. This cooperation is readily apparent in later court cases.

Iran, once the state which, in the midst of political turmoil and military conflict among its Arab neighbours, enjoyed an era of unprecedented economic prosperity and social stability under the administration of the Shah - was suddenly plunged in 1978 into a cultural crisis whose central theme was the common Islamic faith of otherwise diverse groups with disparate political and ideological aspirations. The Iranian revolution, however, was never a merely regional affair, although it started ag...

The spreading of Iceland Scotland Overflow Water (ISOW) in the eastern North Atlantic has largely been studied in an Eulerian frame using numerical models or with observations limited to a few locations. No study to date has provided a comprehensive description of the ISOW spreading pathways from both Eulerian and Lagrangian perspectives. In this paper, we use a combination of previously unreported current meter data, hydrographic data, RAFOS float data, and a high resolution (1/12°) numerical ocean model to study the spreading pathways of ISOW from both of these perspectives. We identify three ISOW transport cores in the central Iceland Basin (∼59°N), with the major core along the eastern boundary of the Reykjanes Ridge (RR) and the other two in the basin interior. Based on trajectories of observed and/or numerical floats seeded along 59°N, we also describe the ISOW spreading pathways and quantify their relative importance. Within 10 years, 7-11% of ISOW from 59°N escapes into the Irminger Sea via gaps in the RR north of the Charlie Gibbs Fracture Zone (CGFZ); the water that moves through these gaps principally originates from the shallower ISOW layer along the RR eastern boundary. 10-13% travels further southward until the CGFZ, where it crosses westward into the western subpolar gyre. 18-21% of ISOW spreads southward along the eastern flank of the Mid-Atlantic Ridge into the Western European Basin (WEB). Most of the remaining water stays in the Iceland Basin over the 10-year period. A model-based investigation provides a first look at the temporal variability of these ISOW pathways. We find that the fraction of southward water exported into the WEB is anti-correlated with the export through the CGFZ, a result assumed to reflect these pathways' interactions with the North Atlantic Current in magnitude and/or position shift.

Full Text Available Servant leadership is a philosophy of communication and leadership whith focus on decentralization, autonomy, mutual respect and commitment to society. In light of universities’ important societal role and importance of equality of academic staff it is presumed that servant leadership suits a university. Prior research indicates the value of servant leadership for universities’ performance. The purpose of the study was to assess servant leadership in the University of Iceland and its correlation with staff job satisfaction using a new Dutch instrument (SLS measuring participants’ attitudes to their next superior. A single item job satisfaction question was included. Results showed considerable practice of servant leadership or 4,19 (scale: 1-6 and the strongest servant leadership characteristic was stewardship, followed by forgiveness and empowerment. 82,6% of participants reported job satisfaction with significant positive correlation with servant leadership. The relatively high degree of servant leadership supports previous study of the uiniversity’s working environment but not recent American studies indicating universities’ a low degree of servant leadership. The degree of servant leadership in the University of Iceland was lower compared to grammar schools (6,46 and general hospital wards (4,33 but identical to hospital emergency care units (4,19. Significant positive correlation of servant leadership with job satisfaction, confirms similar relationships in US universities and in various institutions in Iceland. Results indicate the importance of servant leadership for employees’ job satisfaction, not least empowerment and courage, and this has the potential to support peer management, employee independence and social responsibility of the University of Iceland.

Full Text Available The aim of this paper is to analyse the Icelandic public sector pension system enjoying a third party guarantee. Defined benefit funds fundamentally differ from defined contribution pension funds without a third party guarantee as is the case with the Icelandic general labour market pension funds. We probe the special nature of the public sector pension funds and make a comparison to the defined contribution pension funds of the general labour market. We explore the financial and economic effects of the third party guarantee of the funds, their investment performance and other relevant factors. We seek an answer to the question why time is running out for the country’s largest pension fund that currently faces the prospect of becoming empty by the year 2022.

expense of Ca-free mineral of serpentine. Tremolite were produced after chrysotile, talc, and chlorite, wherever enough Ca2+ ions were released from the associated olivine and/or orthopyroxene by serpentinization. Discussion Petrographical and geochemical studies indicate a greenschist-facies stage (serpentinization and chloritization followed and overprinted by amphibolite-facies metamorphism. The regional metamorphism is verified by the formation of antigorite after lizardite and chrysotile, metamorphic olivine neoblasts after serpentines, chlorite after Cr-spinel, talc after olivine and orthopyroxene, and tremolite after pyroxene, talc, serpentine, and chlorite. The metamorphism imprints on harzburgite and dunite indicate that metamorphism has occurred after melt-rock reactions.

Ari Klængur Jónsson

2017-07-01

Full Text Available Background: Iceland is one of the most gender-equal countries in the world, but one that does not seem to have experienced the same fertility fluctuations as most other countries, following the enhanced role of women in society. Objective: In this study we examine the childbearing trends in Iceland during 1982-2013 by analysing the progressions to parities one, two, and three. We also investigate whether there is evidence of gender preferences for children among Icelandic parents. Methods: Official individual longitudinal register data is used, covering the total female population born in Iceland between 1941 and 1997. The data is analysed by means of event history analysis. Results: We find evidence of tendencies to postpone motherhood during the period, with increases in fertility for women in their 30s and 40s. The propensity to have a second and a third child has not declined; on the contrary, these birth intensities have increased since the mid-1980s. Estimates suggest that Icelandic parents prefer to have daughters. Conclusions: During a period of increased educational attainment and postponed family formation, the resilience of Icelandic fertility is intriguing. Contribution: The study provides the first comprehensive overview of fertility trends in Iceland.

The Kuh-e-Faghan strike-slip fault system (KFF), located to the northern edge of the Lut Block in central Iran, developed through a Neogene-Quaternary pulsed history of eastward fault propagation and fault-related exhumation. This system is a consequence of the residual stresses transmitted from the Arabia-Eurasia convergent plate boundary. Here we integrate structural and textural analysis with new and previously published apatite fission-track (AFT) and apatite (U-Th)/He (apatite He) results, chlorite thermomentry, and hematite (U-Th)/He data from hematite-coated brittle fault surfaces to constrain the timing of tectonic activity and refine patterns of late Miocene-Pliocene burial and exhumation associated with the propagation of the KFF. Twenty-nine hematite (U-Th)/He (hematite He) dates from three striated hematite coated slip surfaces from the KFF fault core and damage zone yield individual dates from 12-2 Ma. Petrographic analysis and chlorite thermometry of a polyphase, fossil fluid system in the KFF fault core document that fluid circulation and mineralization transitioned from a closed system characterized by pressure solution and calcite growth to an open system characterized by hot hydrothermal (T = 239 ± 10 °C) fluids and hematite formation. Hematite microtextures and grain size analysis reveal primary and secondary syntectonic hematite fabrics, no evidence of hematite comminution and similar hematite He closure temperatures ( 60-85 °C) in each sample. Integration of these results with thermal history modeling of AFT and apatite He data shows that KFF activity in the late Miocene is characterized by an early stage of fault nucleation, fluid circulation, hematite mineralization, and eastward propagation not associated with vertical movement that lasted from 12 to 7 Ma. Hematite He, AFT, and apatite He data track a second phase of fault system activity involving fault-related exhumation initiating at 7 Ma and continuing until present time. Our new data

On the 20th of September in 2012, a large debris slide occurred in the Móafellshyrna Mountain in the Tröllaskagi peninsula, central north Iceland. Three factors are likely to have contributed to the failure of the slope: intense precipitation, earthquake activity and thawing of ground ice. The weather conditions prior the slide were somewhat unusual, with a warm and dry summer. From the 20th of August to the 20th of September, about 440 mm of precipitation fell in the area, where the mean annual precipitation at the nearest station is around 670 mm. The slide initiated after this thirty day period of intense precipitation, followed by a seismic sequence in the Eyjafjarðaráll graben, located about 60 km NNE of Móafellshyrna Mountain, a sequence that started on the 19th of September. The slide originated at elevation of 870 m a.s.l. on the NW-slope of the mountain. The total volume of the debris slide is estimated around 500,000 m3 and that its primary cause was intense precipitation. We cannot exclude the influence of the seismic sequence as a secondary contributing factor. The presence of ice-cemented blocks of talus immediately after the debris slide shows that thawing of ground ice could also have played an important role as a triggering factor. Ice-cemented blocks of talus have been observed in the deposits of two other recent landslides in northern Iceland, in the Torfufell Mountain and the Árnesfjall Mountain. The source areas for both the Móafellshyrna and the Torfufell slides are within the lower elevation limit of mountain permafrost in northern Iceland but the source area of the Árnesfjall slide is at much lower elevation, around 350 m a.s.l. The fact that there are now three documented landslides which are linked to ground ice-melting suggests that discontinuous permafrost is degrading in Iceland, consistent with the decadal trend of increasing atmospheric temperature in Iceland due to climate change. This study highlights that ground ice thaw

Full Text Available The purpose of this study was to estimate the seroprevalence of Coxiella burnetii infection in sheep and goat flocks with a history of abortion in different areas of Iran. One thousand and one hundred ovine and 180 caprine samples from 43 sheep and goat flocks in four counties located in the Northeast (Mashhad, Central (Isfahan, Western (Arak, and Southwest (Shiraz Iran were collected randomly between March 2011 and April 2012. The CHEKIT Q fever ELISA kit was used to identify specific antibodies against C. burnetii in sheep and goats. The results showed that the overall seroprevalence of C. burnetii in sheep and goats was 19.5% and 27.2%, respectively. There was a significant difference in seropositivity between sheep and goats (P<0.05. Central Iran significantly had the highest prevalence among the studied areas, especially in goat coxiellosis (23.8% and 40.8% in sheep and goats, respectively. The lowest prevalence in sheep was 12.8% in Northeast Iran while in Western Iran C. burnetii antibodies were absent in goats. The higher prevalence of Q fever in Central Iran may be partly due to persistent favourable conditions to spread C. burnetii in this area including drought and dust storms that originated from neighbouring Iraq and Kuwait. In conclusion, the present study demonstrated the relatively high prevalence of Q fever in sheep and goat flocks with a history of abortion. Therefore, Q fever could be responsible for considerable numbers of ovine and caprine abortions in Iran.

Network analysis of the Íslendinga sögur - the Sagas of Icelanders

Science.gov (United States)

Mac Carron, P.; Kenna, R.

2013-10-01

The Íslendinga sögur - or Sagas of Icelanders - constitute a collection of medieval literature set in Iceland around the late 9th to early 11th centuries, the so-called Saga Age. They purport to describe events during the period around the settlement of Iceland and the generations immediately following and constitute an important element of world literature thanks to their unique narrative style. Although their historicity is a matter of scholarly debate, the narratives contain interwoven and overlapping plots involving thousands of characters and interactions between them. Here we perform a network analysis of the Íslendinga sögur in an attempt to gather quantitative information on interrelationships between characters and to compare saga society to other social networks.

Making Earth's earliest continental crust - an analogue from voluminous Neogene silicic volcanism in NE-Iceland

Borgarfjörður Eystri in NE-Iceland represents the second-most voluminous exposure of silicic eruptive rocks in Iceland and is a superb example of bimodal volcanism (Bunsen-Daly gap), which represents a long-standing controversy that touches on the problem of crustal growth in early Earth. The silicic rocks in NE-Iceland approach 25 % of the exposed rock mass in the region (Gústafsson et al., 1989), thus they significantly exceed the usual ≤ 12 % in Iceland as a whole (e.g. Walker, 1966; Jonasson, 2007). The origin, significance, and duration of the voluminous (> 300 km3) and dominantly explosive silicic activity in Borgarfjörður Eystri is not yet constrained (c.f. Gústafsson, 1992), leaving us unclear as to what causes silicic volcanism in otherwise basaltic provinces. Here we report SIMS zircon U-Pb ages and δ18O values from the region, which record the commencement of silicic igneous activity with rhyolite lavas at 13.5 to 12.8 Ma, closely followed by large caldera-forming ignimbrite eruptions from the Breiðavik and Dyrfjöll central volcanoes (12.4 Ma). Silicic activity ended abruptly with dacite lava at 12.1 Ma, defining a ≤ 1 Myr long window of silicic volcanism. Magma δ18O values estimated from zircon range from 3.1 to 5.5 (± 0.3; n = 170) and indicate up to 45 % assimilation of a low-δ18O component (e.g. typically δ18O = 0 ‰, Bindeman et al., 2012). A Neogene rift relocation (Martin et al., 2011) or the birth of an off-rift zone to the east of the mature rift associated with a thermal/chemical pulse in the Iceland plume (Óskarsson & Riishuus, 2013), likely brought mantle-derived magma into contact with fertile hydrothermally-altered basaltic crust. The resulting interaction triggered large-scale crustal melting and generated mixed-origin silicic melts. Such rapid formation of silicic magmas from sustained basaltic volcanism may serve as an analogue for generating continental crust in a subduction-free early Earth (e.g. ≥ 3 Ga, Kamber et

Full Text Available The Kamarbon Jurassic alkaline basic intrusion crops out in Central Alborz, north Iran, along the northern margin of the Alpine-Himalayan belt. The intrusion includes foid gabbros at the margins and foid monzodiorites towards the center. The foid monzodiorites are considered as the evolved melts after the fractional crystallization mostly of olivine and clinopyroxene from a foid gabbro parental magma. Based on mass balance calculation the evolution of the Kamarbon alkaline gabbro could be explained by 19.2% fractionation of clinopyroxene, 13.8% of olivine, 3% of plagioclase and 1.0% Ti-Magnetite, with 63% of residual liquid. REE inversion modeling indicates that the Kamarbon intrusion magma was generated by low degrees (<3% of partial melting from a garnet-bearing mantle source. In primitive mantle-normalized incompatible element diagrams, the Kamarbon rocks show enrichment in LILE elements (Ba, Rb, Sr and Th, HFSE elements (Nb, Ta, Ti, Zr and Hf and P and depletion in K, Y and HREE (Yb, Lu which are similar to patterns of HIMU-OIBs or intraplate alkaline magmas. According to the existence of extensional phases and occurrence of different rifting during late Triassic to middle Jurassic in Central Alborz, the formation of Kamarbon intrusion could be related to an intracontinental rifting.

One of the main objectives of the HITI project (HIgh Temperature Instruments for supercritical geothermal reservoir characterization and exploitation), partially funded by the European Union, is to develop methods to characterize the reservoir and fluids of deep and very high temperature geothermal systems. The chemical composition of geothermal waters in terms of major and trace elements is related to the temperature, the degree of water/rock interaction and the mineralogical assemblage of the bedrock. Traditional geothermometers, such as silica, Na-K, Na-K-Ca or K-Mg applied to geothermal waters, make it possible to estimate the temperature at depth of the reservoir from which the waters are derived. However, the values estimated for deep temperature are not always concordant. The chemical geothermometer Na/Li which presents the singularity of associating two chemical elements, one a major element (sodium) and the other a trace element (Li), can be also used and gives an additional temperature estimation. The primary objective of this work was to better understand the behavior of this last geothermometer using the isotopic systematics of Li in order to apply it at very high temperature Icelandic geothermal systems. One particularly important aspect was to establish the nature, extent and mechanism of Li isotope fractionation between 100 and 350°C during water/rock interaction. For that purpose, we measured Li isotopes of about 25 geothermal waters from Iceland by using a Neptune MC-ICP-MS that enabled the analysis of Li isotopic ratios in geothermal waters with a level of precision of ±0.5‰ (2 standard deviations) on quantities of 10-50 ng of Li. Geothermal waters from Reykjanes, Svartsengi, Nesjavellir, Hveragerdi, Namafjall and Krafla geothermal systems were studied and particular emphasis was placed on the characterization of the behavior of Li isotopes in this volcanic context at high temperature with or without the presence of seawater during water

Greenland is the second largest reservoir of water on Earth and about 80% of its surface is covered by ice. It is mainly composed of Archean blocks that collided during the Early Proterozoic. Indirect methods have been used to study its subglacial thermal conditions, geology and lithospheric structure. Numerous regions of basal melting are identified in the central and north Greenland but their relationship with geothermal heat flux is not yet clear. Crustal thickness derived by seismology and gravity data are consistent, showing no significant lateral variations, and providing average values of about 40 and 36 km respectively. Even though Greenland is considered a craton its crust has been affected by the presume passage of the Iceland hotspot since at least 100 Ma. Here we present the newest and highest resolution Curie Depth and geothermal heat flux maps for Greenland as well as their associated uncertainties. For estimating the Curie Depths we applied spectral methods to aeromagnetic data from the World Digital Magnetic Anomaly Map WDMAM2.0. Calculated Curie Depths vary from 25 to 50 km with shallower values located to the east. A thermal model is built based on the 1D heat conduction equation and considering steady state conditions. The thermal parameters are then optimized using local values derived from direct measurements, temperature profiles and more indirect methods such as radar imaging. The heat flux distribution shows higher spatial variability and a very different pattern than previously proposed and with values of 50-80 mW/m2. We identify a NW-SE high heat flux feature crossing Greenland which we correlate with the Iceland hotspot track. Additionally, to evaluate the lithospheric structure we calculate the Bouguer anomaly from GOCO5s satellite free air data and construct several gravity models across the proposed hotspot track. We show that a dense lower crust body in the same location the high heat flux trend is permissible from a gravimetric

Globalization has facilitated the employability of doctors almost anywhere in the world. In recent years, the migration of doctors seems to have increased. However, we lack studies on doctors' migration from developed countries. Because the economic recession experienced by many countries might have affected the migration of doctors, research on this topic is important for the retention of doctors. Iceland was hit hard by the economic recession in 2008. Therefore, we want to explore how many specialist doctors in Iceland have considered migrating and whether economic factors at work and in private life, such as extensive cost-containment initiatives at work and worries about personal finances, are related to doctors' migration considerations. In 2010, all doctors in Iceland registered with the Icelandic Medical Association were sent an electronic cross-sectional survey by email. The 467 specialists who participated in this study represent 55% of all specialist doctors working in Iceland. Information on doctors' contemplation of migration was available from responses to the question: "Have you considered moving and working abroad?" The predictor variables in our logistic regression model are perceived cost-containment initiatives at work, stress related to personal finances, experience of working abroad during vacations, job dissatisfaction, job position, age, and gender. Sixty-three per cent of Iceland's specialist doctors had considered relocation abroad, 4% were moving in the next year or two, and 33% had not considered relocating. Logistic regression analysis shows that, controlling for age, gender, job position, job satisfaction, and experience of working abroad during vacations, doctors' migration considerations were significantly affected by their experiences of cost-containment initiatives at work (odds ratio (OR) = 2.0, p Economic factors affect whether specialist doctors in Iceland consider migration.

Interaction of the Faroe Bank Channel overflow with Iceland Basin intermediate waters

Ullgren, Jenny E.; Fer, Ilker; Darelius, Elin; Beaird, Nicholas

2014-01-01

The narrow and deep Faroe Bank Channel (FBC) is an important pathway for cold, dense waters from the Nordic Seas to flow across the Iceland-Scotland ridge into the North Atlantic. The swift, turbulent FBC overflow is associated with strong vertical mixing. Hydrographic profiles from a shipboard survey and two Slocum electric gliders deployed during a cruise in May-June 2012 show an intermediate water mass characterized by low salinity and low oxygen concentration between the upper waters of Atlantic origin and the dense overflow water. A weak low-salinity signal originating north-east of Iceland is discernible at the exit of the FBC, but smeared out by intense mixing. Further west (downstream) marked salinity and oxygen minima are found, which we hypothesize are indicators of a mixture of Labrador Sea Water and Intermediate Water from the Iceland Basin. Water mass characteristics vary strongly on short time scales. Low-salinity, low-oxygen water in the stratified interface above the overflow plume is shown to move along isopycnals toward the Iceland-Faroe Front as a result of eddy stirring and a secondary, transverse circulation in the plume interface. The interaction of low-salinity, low-oxygen intermediate waters with the overflow plume already at a short distance downstream of the sill, here reported for the first time, affects the final properties of the overflow waters through entrainment and mixing.

Floating like a cork: The importance of glacial isostasy in the deglaciation progress in Iceland

Science.gov (United States)

Norddahl, H.; Ingolfsson, O.

2016-12-01

Being positioned on top of a hotspot and between two spreading ocean plates explains rheological structure of Iceland and the properties of a 30-35 km thick lithosphere, possibly with high proportion of partial melt, on top of a low viscous asthenosphere below Iceland, in the middle of the North Atlantic Ocean. Rapid variations in glacier loading on the Iceland crust have been proved to generate more or less an instantaneous depression or uplift of the crust and, thus, uphold both temporal and spacial glacio-isostatic equilibrium. Formation of a shoreline requires at least temporal equilibrium between glacial isostasy and eustasy. Eminent raised shorelines - found throughout Iceland - were formed during two separate but consecutive culmination of climatically induced glacier re-advance and consequent transgression of relative sea-level in Younger Dryas and Preboreal times (12.0 and 11.3 kcal BP). A Marine Limit shoreline in W Iceland was formed at 14.7 kcal BP, subsequent to a collapse-like retreat of the marine based part of the Icelandic Ice Sheet (IIS) and just prior to the onset of the Bølling warming, i.e. during a period of anticipated rapid isostatic uplift. A temporary glacio-isostatic equilibrium at that time is best explained by changes in the mode of deglaciation generating dynamic changes within the Ice Sheet itself, changes that resulted in reduced rates of mass-loss and glacio-isostatic uplift to such a degree that a temporal quasi-equilibrium between eustatic rise and isostatic uplift was established. Formation of well-developed raised shoreline is generally regarded as a deglaciation proxy signaling large ice volume changes. Formation of the ML shoreline in W Iceland during the rapid climatic improvement at the beginning of the Bølling/Allerød Interstadial underlines the importance of, beside the geological data, also to take into consideration physical properties of both the lithosphere and asthenosphere in each location.

Self Censorship among Icelandic Journalists

Full Text Available The discussion on media self-censorship has flourished in Iceland after the attacks on the Charlie Hebdo editorial offices in January 2015 and after some dramatic changes in the top management and owner-groups of some of the media firms. But what is this experience that journalists describe as self censorship? This paper attempts to answer two main research questions. On the one hand the question how journalists understand the concept of selfcensorship. On the other hand the question: what is the experience of Icelandic journalist of self-censorship? The approach is the one of a qualitative research and is based on interviews with six experienced journalists. The main findings suggest important influence of the social discourse on news and news values of journalists and their tendency for self-censorship. This discourse is partly directed by politicians and influential bloggers and also by a massive discussion by active social media users. Furthermore the findings suggest, that ownership and the location of the particular medium where a journalist works in the lineup of different commercial-political blocks in the media market, is important for self-censorship. Finally it seems that journalists understand the concept selfcensorship in a different manner and that it is important to define the term carefully if it is to be used as an analytical tool.

Full Text Available Introduction: Solar radiation (Rs energy received at the Earth's surface is measured usingclimatological variables in horizontal surface and is widely used in various fields. Domination of hot and dry climates especially in the central regions of Iran results from decreasing cloudiness and precipitation and increasing sunshine hours, which shows the high potential of solar energy in Iran. There is a reasonable climatic field and solar radiation in most of regions and seasons which have provided an essential and suitable field to use and extend new and pure energy. Materials and Methods: One of the common methods to estimate the solar energy received by the earthis usingtemperature variables in any place . An empirical model is proposed to estimate the solar energy as a function of other climatic variables (maximum temperature recorded in 50 climatological, conventional stations; this model is helpful inextending the climatological solar-energy estimation in the study area. The mean values of both measured and estimated solar energy wereobjectively mapped to fill the observation gaps and reduce the noise associated with inhomogeneous statistics and estimation errors. This analysis and the solar irradiation estimation method wereapplied to 50 different climatologicalstations in Iran for monthly data during1980–2005.

230Th-238U disequilibria in historical lavas from Iceland

The 230 Th- 238 U disequilibrium studies on historical lavas from Iceland show a relative homogeneity for Th/U ratios and also a variation for ( 230 Th/ 232 Th) activity ratios at the scale of the island. The ( 230 Th/ 238 U) disequilibrium ratio is always greater than 1 which indicates that partial melting produces magmas with Th/U ratios greater than those of the mantle source. Furthermore, there seems to be a correlation between the variations of ( 230 Th/ 232 Th) (and delta 18 O) ratios and the geographical location of the samples along the active zones of Iceland. We develop and discuss several models in order to explain these variations. (orig.)

Campylobacter jejuni isolates from various sources in Iceland were genotyped with the aim of assessing the genetic diversity, population structure, source distribution and campylobacter transmission routes to humans. A collection of 584 Campylobacter isolates were collected from clinical cases, food, animals and environment in Iceland in 1999-2002, during a period of national Campylobacter epidemic in Iceland. All isolates were characterized by pulse field gel electrophoresis (PFGE), and selected subset of 52 isolates representing the diversity of the identified PFGE types was further genotyped using multilocus sequence typing (MLST) and fla-SVR sequencing to gain better insight into the population structure. The results show a substantial diversity within the Icelandic Campylobacter population. Majority of the human Campylobacter infections originated from domestic chicken and cattle isolates. MLST showed the isolates to be distributed among previously reported and common sequence type complexes in the MLST database. The genotyping of Campylobacter from various sources has not previously been reported from Iceland, and the results of the study gave a valuable insight into the population structure of Camp. jejuni in Iceland, source distribution and transmission routes to humans. The geographical isolation of Iceland in the north Atlantic provides new information on Campylobacter population dynamics on a global scale.

Iceland and the EU’s Common Security and Defence Policy: Challenge or Opportunity?

Directory of Open Access Journals (Sweden)

Alyson J.K. Bailes

2012-06-01

Full Text Available Iceland had initial misgivings about the EU’s capacity created in 1999 for military crisis management. In the current debate over Iceland’s EU application, questions have been raised about the possible impact of CSDP on the nation’s non-military status. In fact the CSDP is designed to respect national choices in defence; requires unanimity on new actions; and allows case-by-case decisions on participation. Preliminary study of six other small states in the EU suggests that none of them has been obliged by membership to abandon national preferences in this field, though all have made special efforts to support EU police and civilian operations - an area where Iceland is also well qualified to contribute. The more significant effects of EU membership for Icelandic security might in fact come in other, ‘softer’ areas including EU obligations for mutual assistance in civil emergencies.

Cereal production, high status and climate in Medieval Iceland

Science.gov (United States)

Erlendsson, Egill; Riddell, Scott

2017-04-01

At Hrísbrú (formerly the medieval Mosfell estate) in the Mosfell Valley, southwest Iceland, archaeologists have excavated a medieval skáli (hall) proposed to be the high status residence of a chieftain. This is indicated by the size of the skáli, artefacts (foreign goods), archaeofaunal (cattle/sheep bone) ratios and macrobotanical remains (cereal grain). The analysis of pollen from nearby natural contexts suggests that cereals were grown locally. Using multiple profile palynological approach, this paper examines if the apparent cereal production is representative of high status in the Icelandic context. First as a correlate by confirming that cereals were grown in association with the archaeological features characteristic of high status; secondly, as an indicator in its own right through comparison with other palynological datasets from inferred lower status farms. The presence or absence of cereal-type pollen (cf. barley) and other arable correlates was examined for each site. The results suggest that medieval cereal cultivation in the Mosfell Valley was confined to the landholding of the medieval Mosfell estate. This feature is seen as an attribute of the locale's greater status in relation to the other farms in Mosfell Valley. The abandonment of cereal cultivation at the Mosfell estate around AD 1200 is probably associated with interactions between changes in the nation's social power structure and how marginal cereal production in Iceland was (and is) in terms of climate.

Local food in Iceland: identifying behavioral barriers to increased production and consumption

Ósk Halldórsdóttir, Þórhildur; Nicholas, Kimberly A.

2016-11-01

Increased production and consumption of local food may reduce the negative environmental, social, and economic impacts of industrialized and globalized food production. Here we examined potential barriers to increasing production and consumption of food produced in Iceland. First, we developed a new framework to address the behaviors of production and consumption simultaneously, to comprehensively analyze their potential barriers. We examined structural barriers by estimating the food production capacity of Iceland, and cultural and personal barriers through survey data on cultural norms and purchasing behavior from Matís, a research and development company. We found no structural barriers preventing Iceland from increasing production of local cereals, which would compliment current local production of meat and dairy and reduce reliance on imports, currently at 50% of the daily caloric intake. However, if food production became entirely local without changing the current mix of crops grown, there would be a 50% reduction in diversity (from 50 to 25 items in eight out of ten food categories). We did not identify any cultural barriers, as survey results demonstrated that consumers hold generally positive worldviews towards local food, with 88% satisfied with local food they had purchased. More than two-thirds of consumers regarded supporting the local farmer and considerations such as environmentally friendly production, fewer food miles, lower carbon footprint as important. However, they rated the local food they have access to as lower in meeting sustainability criteria, showing that they make justifications for not choosing local food in practice. This is a personal barrier to increased consumption of local food, and implies that marketing strategies and general knowledge connected to local food in Iceland might be improved. Although the results apply to the case of Iceland, the method of identifying behavioral barriers to change is applicable to other countries

We used pitfall trapping to investigate the effects of elevation, plant density and soil structure on species diversity and the impact of these habitat factors on lizard habitat selectivity in the Qom Province in the Central Plateau of Iran. From a total of 12 1-ha plots, we captured 363 individuals of 15 species of lizards (six species of Lacertidae, five species of Agamidae, two species of Gekkonidae, one species of Varanidae and one species of Scincidae). A generalized linear model (GLM) determined that elevation was the most important factor impacting species diversity. The highest species diversity was at the intermediate elevation (1289 m). Abundance of 6 out of 15 species showed strong relationships with some habitat factors. These relationships were demonstrated by habitat selectivity index (Ivlev's index). Our result supports other surveys that showed that elevation plays an important role in determining lizard species diversity. PMID:24349557

Full Text Available Particulate matter mass concentrations and size fractions of PM1, PM2.5, PM4, PM10, and PM15 measured in transversal horizontal profile of two dust storms in southwestern Iceland are presented. Images from a camera network were used to estimate the visibility and spatial extent of measured dust events. Numerical simulations were used to calculate the total dust flux from the sources as 180,000 and 280,000 tons for each storm. The mean PM15 concentrations inside of the dust plumes varied from 10 to 1600 µg·m−3 (PM10 = 7 to 583 µg·m−3. The mean PM1 concentrations were 97–241 µg·m−3 with a maximum of 261 µg·m−3 for the first storm. The PM1/PM2.5 ratios of >0.9 and PM1/PM10 ratios of 0.34–0.63 show that suspension of volcanic materials in Iceland causes air pollution with extremely high PM1 concentrations, similar to polluted urban areas in Europe or Asia. Icelandic volcanic dust consists of a higher proportion of submicron particles compared to crustal dust. Both dust storms occurred in relatively densely inhabited areas of Iceland. First results on size partitioning of Icelandic dust presented here should challenge health authorities to enhance research in relation to dust and shows the need for public dust warning systems.

Few studies currently exist that aim to validate a proxy chironomid-temperature reconstruction with instrumental temperature measurements. We used a reconstruction from a chironomid percentage abundance data set to produce quantitative summer temperature estimates since AD 1650 for NW Iceland through a transfer function approach, and validated the record against instrumental temperature measurements from Stykkishólmur in western Iceland. The core was dated through Pb-210, Cs-137 and tephra analyses (Hekla 1693) which produced a well-constrained dating model across the whole study period. Little catchment disturbance, as shown through geochemical (Itrax) and loss-on-ignition data, throughout the period further reinforce the premise that the chironomids were responding to temperature and not other catchment or within-lake variables. Particularly cold phases were identified between AD 1683-1710, AD 1765-1780 and AD 1890-1917, with relative drops in summer temperatures in the order of 1.5-2°C. The timing of these cold phases agree well with other evidence of cooler temperatures, notably increased extent of Little Ice Age (LIA) glaciers. Our evidence suggests that the magnitude of summer temperature cooling (1.5-2°C) was enough to force LIA Icelandic glaciers into their maximum Holocene extent, which is in accordance with previous modelling experiments for an Icelandic ice cap (Langjökull).

Full Text Available The distribution and abundance of blue whales (Balaenoptera musculus was assessed from ship surveys conducted in the Central and Northeast Atlantic in 1987, 1989, 1995 and 2001. Blue whales were most commonly sighted off western Iceland, and to a lesser extent northeast of Iceland. They were very rare or absent in the Northeast Atlantic. Sightings were combined over all surveys to estimate the detection function using standard line transect methodology, with the addition of a covariate to account for differences between surveys. Total abundance was highest in 1995 (979, 95% CI 137-2,542 and lowest in 1987 (222, 95% CI 115-440. Uncertainty in species identity had little effect on estimates of abundance. There was a significant positive trend in abundance northeast of Iceland and in the total survey area.

Two articles in the Geopolitics subject: (1) Even before Iran's presidential election, its oil and gas industries were struggling to meet the nation's energy needs and export aspirations. Following what some see as a thinly-veiled military coup, the outlook looks even bleaker - not just for the Iranian people, but for the global energy economy; (2) South Pars, is Iran's portion of the world's largest non-associated gas field. Shared with Qatar, which calls its portion the North Field, this immense geological structure holds over half of Iran's 27,000 bcm (billion cubic metres) of proved gas reserves. That is more than any country in the world, except Russia. With gas riches like these, it is no surprise that Iran has long harboured ambitions to become one of the world's major exporters

The molecular epidemiology of HIV-1 in Iceland has not been described so far. Detailed analyses of the dynamics of HIV-1 can give insights for prevention of virus spread. The objective of the current study was to characterize the genetic diversity and transmission dynamics of HIV-1 in Iceland. Partial HIV-1 pol (1020bp) sequences were generated from 230 Icelandic samples, representing 77% of all HIV-1 infected individuals reported in the country 1985-2012. Maximum likelihood phylogenies were reconstructed for subtype/CRF assignment and determination of transmission clusters. Timing and demographic growth patterns were determined in BEAST. HIV-1 infection in Iceland was dominated by subtype B (63%, n=145) followed by subtype C (10%, n=23), CRF01_AE (10%, n=22), sub-subtype A1 (7%, n=15) and CRF02_AG (7%, n=15). Trend analysis showed an increase in non-B subtypes/CRFs in Iceland over the study period (p=0.003). The highest proportion of phylogenetic clustering was found among injection drug users (IDUs; 89%), followed by heterosexuals (70%) and men who have sex with men (35%). The time to the most recent common ancestor of the oldest subtype B cluster dated back to 1978 (median estimate, 95% highest posterior density interval: 1974-1981) suggesting an early introduction of HIV-1 into Iceland. A previously reported increase in HIV-1 incidence among IDUs 2009-2011 was revealed to be due to two separate outbreaks. Our study showed that a variety of HIV-1 subtypes and CRFs were prevalent in Iceland 1985-2012, with subtype B being the dominant form both in terms of prevalence and domestic spread. The rapid increase of HIV-1 infections among IDUs following a major economic crisis in Iceland raises questions about casual associations between economic factors, drug use and public health.

Islamic politics and women's quest for gender equality in Iran.

Science.gov (United States)

Hoodfar, Homa; Sadr, Shadi

2010-01-01

The unification of a strong and authoritarian state with religious laws and institutions after the 1979 revolution in Iran has resulted in the creation of a dualistic state structure in which non-elected and non-accountable state authorities and institutions-the majority of whom have not accepted either the primacy of democracy nor the premise of equality between men and women (or Muslims and non-Muslims)-are able to oversee the elected authorities and institutions. The central question posed by this paper is whether a religious state would be capable of democratising society and delivering gender equality. By analysing the regime's gender policies and political development, the paper suggests that, at least in the case of Iran and Shi'ism, the larger obstacle to gender (and minorities') equality has more to do with the undemocratic state-society relations that persist in Iran and less to do with the actual or potential compatibility (or lack thereof) of religious traditions or practices with democratic principles.

Monthly gravity field models from the GRACE satellite mission are widely used to determine ice mass changes of large ice sheets as well as smaller glaciers and ice caps. Here, we investigate in detail the ice mass changes of the Icelandic ice caps as derived from GRACE data. The small size...... of the Icelandic ice caps, their location close to other rapidly changing ice covered areas and the low viscosity of the mantle below Iceland make this especially challenging. The mass balance of the ice caps is well constrained by field mass balance measurements, making this area ideal for such investigations. We...... the Little Ice Age (∼ 1890 AD). To minimize the signal that leaks towards Iceland from Greenland, we employ an independent mass change estimate of the Greenland Ice Sheet derived from satellite laser altimetry. We also estimate the effect of post Little Ice Age glacial isostatic adjustment, from knowledge...

Earthquake Prediction Research In Iceland, Applications For Hazard Assessments and Warnings

Science.gov (United States)

Stefansson, R.

Earthquake prediction research in Iceland, applications for hazard assessments and warnings. The first multinational earthquake prediction research project in Iceland was the Eu- ropean Council encouraged SIL project of the Nordic countries, 1988-1995. The path selected for this research was to study the physics of crustal processes leading to earth- quakes. It was considered that small earthquakes, down to magnitude zero, were the most significant for this purpose, because of the detailed information which they pro- vide both in time and space. The test area for the project was the earthquake prone region of the South Iceland seismic zone (SISZ). The PRENLAB and PRENLAB-2 projects, 1996-2000 supported by the European Union were a direct continuation of the SIL project, but with a more multidisciplinary approach. PRENLAB stands for "Earthquake prediction research in a natural labo- ratory". The basic objective was to advance our understanding in general on where, when and how dangerous NH10earthquake motion might strike. Methods were devel- oped to study crustal processes and conditions, by microearthquake information, by continuous GPS, InSAR, theoretical modelling, fault mapping and paleoseismology. New algorithms were developed for short term warnings. A very useful short term warning was issued twice in the year 2000, one for a sudden start of an eruption in Volcano Hekla February 26, and the other 25 hours before a second (in a sequence of two) magnitude 6.6 (Ms) earthquake in the South Iceland seismic zone in June 21, with the correct location and approximate size. A formal short term warning, although not going to the public, was also issued before a magnitude 5 earthquake in November 1998. In the presentation it will be shortly described what these warnings were based on. A general hazard assessmnets was presented in scientific journals 10-15 years ago assessing within a few kilometers the location of the faults of the two 2000 earthquakes and suggesting

Full Text Available BACKGROUND: Individuals are faced with numerous stressful life events which can negatively influence mental health. Many individuals use smoking as a means of confronting stress. Given the relatively high prevalence of smoking in central Iran, the present study was conducted to compare stress levels in smokers, non-smokers and those who had quit smoking.    METHODS: This study was conducted as part of Isfahan Cardiovascular Research Program on 9752 individuals in the cities of Isfahan, Arak, and Najafabad in 2008. Sampling was performed using multi-stage cluster randomization method. Data on age, sex, demographic characteristics, and smoking status was collected through interviews. Stress level detected by General Health questionnaire.Logistic regression and chi- squere test was used for data analyzing.    RESULTS: In the present study, 30% of non-smokers, 32.1% ex- smoker and 36.9% of smokers had GHQ of 4 and higher (P = 0.01. In regression analysis, the final model which was controlled for age, sex, socioeconomic statues (including place of residence, marital status and education level showed that the odds ratio of stress in smokers and ex- smoker was significantly higher than in non-smokers (OR = 1.66 and OR = 1.12, respectively.    CONCLUSION: Since in conducted studies, mental problems and stresses have had an important role in people’s smoking, it seems suitable to use the results of this study to present intervention for correct methods of coping with stress towards reducing the prevalence of smoking in the community.Keywords: Cigarette, Stress, Community-based Program.

Iceland is exposed to rapid and dynamic landscape changes caused by natural processes and man-made activities, which impact and challenge the country. Fast and reliable mapping and monitoring techniques are needed on a big spatial scale. However, currently there is lack of operational advanced information processing techniques, which are needed for end-users to incorporate remote sensing (RS) data from multiple data sources. Hence, the full potential of the recent RS data explosion is not being fully exploited. The project Environmental Mapping and Monitoring of Iceland by Remote Sensing (EMMIRS) bridges the gap between advanced information processing capabilities and end-user mapping of the Icelandic environment. This is done by a multidisciplinary assessment of two selected remote sensing super sites, Hekla and Öræfajökull, which encompass many of the rapid natural and man-made landscape changes that Iceland is exposed to. An open-access benchmark repository of the two remote sensing supersites is under construction, providing high-resolution LIDAR topography and hyperspectral data for land-cover and landform classification. Furthermore, a multi-temporal and multi-source archive stretching back to 1945 allows a decadal evaluation of landscape and ecological changes for the two remote sensing super sites by the development of automated change detection techniques. The development of innovative pattern recognition and machine learning-based approaches to image classification and change detection is one of the main tasks of the EMMIRS project, aiming to extract and compute earth observation variables as automatically as possible. Ground reference data collected through a field campaign will be used to validate the implemented methods, which outputs are then inferred with geological and vegetation models. Here, preliminary results of an automatic land-cover classification based on hyperspectral image analysis are reported. Furthermore, the EMMIRS project

Isotope geochemistry of hydrothermal alteration in East of Esfahan, Central Iran

Taghipour, Sedigheh; Taghipour, Batoul

2010-05-01

In the Cenozoic magmatic belt of Central Iran, the Eocene volcanics and pyroclastics from the East of Esfahan underwent extensive hydrothermal alteration. The Eocene volcanics composed mostly of andesite lava and tuffs have been altered. The survey area is laterally zoned from an inner quartz-sericite alteration zone to an outer propylitic zone. Quartz-sericite alteration is predominant (>95%), but smaller zones of alunite-jarosite and silicified zones are present and superimposed onto a quartz-sericite alteration. In the quartz-sericite zone all altered rocks are light grayish to whitish in color and porphyritic with aphanitic groundmass. Concentrations of alunite and jarosite veinlets and stockworks are dispersed irregularly in this zone. Alunite and jarosite occur also as coatings on fractured rocks. All types of alunite occurrences are brick-red, cream, white and buff in colors, while jarosite is brown to rusty in colors. To verify, chemical composition of alunite and jarosite were identified by X-ray diffraction in mineral assemblages. Major alteration zones show inclusions of propylite, quartz sericite, advanced argillic and silicified zones. These alunites are mainly porcelaneous and their compositions show a solid solution between alunite and jarosite. In alteration zones, the mineral assemblage is characterized by alunite-jarosite + quartz + sericite + alkali feldspars + chlorite ± turquoise ± barite ± iron oxides. There are numerous alunite and jarosite occurrences, mainly as veinlets, in parts of the advanced argillic zone. Alunite δ18O and δ D values range from -1.76 to 8.81‰ and from -52.86 to -129.26‰ respectively. Field observations, mineralogical evidence and results from light element stable isotope data (δ18O, δ D and δ34S); indicate that in this area alunitization is supergene in origin.

Organising pneumonia (OP) is a relatively rare interstitial lung disease. It s definition is based on a characteristic histological pattern in the presence of certain clinical and radiological features. Organising pneumonia represents also what has been called Bronchiolitis Obliterans Organising Pneumonia (BOOP). Recently it has been recommended to call OP cryptogenic organising pneumonia (COP) when no definite cause or characteristic clinical context is found and secondary organising pneumonia (SOP) when causes can be identified such as infection or it occurs in a characteristic clinical context such as connective tissue disorder. The most common clinical symptoms are dyspnea, cough, fever and general malaise. It is common that symptoms have been present for some weeks before the diagnosis is made. Patients commonly have lowered PO2 and a mildly restrictive spirometry. Radiographic features are most often patchy bilateral airspace opacities but an interstitial pattern or focal opacities can also be seen. Most of patients respond well to steroids but relapses are quite common. The aim of this paper is to present an overview of the disease and the main results from studies on OP in Iceland. The mean annual incidence for OP in Iceland was 1.97/100,000 inhabitants. Annual incidence for COP was 1.10/100,000 and 0.87/100,000 for SOP. This is higher than in most other studies. In Iceland patients with OP had a higher standardized mortality ratio than the general population despite good clinical responses. No clinical symptoms could separate between SOP and COP.

2008-03-01

Full Text Available Abstract Background Previous research has shown that between 80 and 90 percent of adult smokers report having started smoking before 18 years of age. Several studies have revealed that multiple social factors influence the likelihood of smoking during adolescence, the period during which the onset of smoking usually occurs. To better understand the social mechanisms that influence adolescent smoking, we analyzed the relationship and relative importance of a broad spectrum of social variables in adolescent smoking in Iceland, a Nordic country with high per-capita income. Methods We used cross-sectional data from 7,430 14- to 16 year-old students (approximately 81% of all Icelanders in these age cohorts in the 2006 Youth in Iceland study. The Youth in Iceland studies are designed to investigate the role of several cognitive, behavioral, and social factors in the lives of adolescents, and the data collected are used to inform the design, implementation, and evaluation of substance use prevention programs that are being developed by Icelandic social scientists, policy makers, and practitioners. Results Our analysis revealed that friends' smoking behavior and attitude toward smoking were strongly associated with adolescent smoking and other tobacco use, as well as alcohol consumption during the previous 30 days. Main protective factors were parent's perceived attitude toward smoking, the quantity of time spent with parents, absence of serious verbal conflict between parents and adolescents, and participation in physical activity. Family structure was related to adolescent smoking to a small extent, but other background factors were not. Conclusion We conclude that multiple social factors are related to adolescent smoking. Parents and other primary preventive agents need to be informed about the complicated nature of the adolescent social world in order to maximize their impact.

Multiple Stage Ore Formation in the Chadormalu Iron Deposit, Bafq Metallogenic Province, Central Iran: Evidence from BSE Imaging and Apatite EPMA and LA-ICP-MS U-Pb Geochronology

Full Text Available The Chadormalu magnetite-apatite deposit in Bafq metallogenic province, Central Iran, is hosted in the late Precambrian-lower Cambrian volcano-sedimentary rocks with sodic, calcic, and potassic alterations characteristic of iron oxide copper-gold (IOCG and iron oxide-apatite (IOA ore systems. Apatite occurs as scattered irregular veinlets and disseminated grains, respectively, within and in the marginal parts of the main ore-body, as well as apatite-magnetite veins in altered wall rocks. Textural evidence (SEM-BSE images of these apatites shows primary bright, and secondary dark areas with inclusions of monazite/xenotime. The primary, monazite-free fluorapatite contains higher concentrations of Na, Si, S, and light rare earth elements (LREE. The apatite was altered by hydrothermal events that led to leaching of Na, Si, and REE + Y, and development of the dark apatite. The bright apatite yielded two U-Pb age populations, an older dominant age of 490 ± 21 Ma, similar to other iron deposits in the Bafq district and associated intrusions, and a younger age of 246 ± 17 Ma. The dark apatite yielded a U-Pb age of 437 ± 12 Ma. Our data suggest that hydrothermal magmatic fluids contributed to formation of the primary fluorapatite, and sodic and calcic alterations. The primary apatite reequilibrated with basinal brines in at least two regional extensions and basin developments in Silurian and Triassic in Central Iran.

Geodynamics of rift-plume interaction in Iceland as constrained by new 40Ar/ 39Ar and in situ U-Pb zircon ages

2011-11-01

The interaction between a rift zone and a mantle plume leads to exceptional situations in Iceland where the island is 1.5 wider than expected, given the North-Atlantic spreading rate. In order to give a better idea of the timeframe of this evolution, we present 32 new 40Ar/ 39Ar and in-situ U-Pb dating on zircon from 16 volcanic systems located from the west to east coasts of Iceland. The North Iceland Rift Zone (NIRZ) was initiated at least 12 Ma ago. Furthermore, during these last 12 Ma, the NIRZ half spreading rate was between 0.7 and 1.2 cm/yr and it propagated to the south at a rate of 1.0-1.2 cm/yr. The excess width of Iceland can thus not be explained by faster spreading rate in the past. Here we discuss a model that explains the ~ 200 km 'excess' of crust, taking into account the eastward relocation of the rift zone and corresponding older crustal capture over the course of Iceland's geological history. The most recent rift relocation is dated at approximately 6 Ma at Snæfellsnes Peninsula in the west, whereas the oldest volcanic systems (15-13 Ma) from the extreme north east of Iceland were most likely generated at the Kolbeinsey ridge north of Iceland rather than in the NIRZ itself. The need for rift relocations and crustal capture to explain the width of Iceland strongly suggests that during rift-plume interaction the mantle plume plays an active role. It forces the active rift zone to be frequently relocated by rift jumps above its center leaving inactive rift zones as older synclines in the geological record. This result in an eastward position of the rift zone in Iceland relative to the North Atlantic ridge, and it can be predicted that in a few tens of millions of years the Mid-Atlantic ridge and the Icelandic plume may become decoupled.

Cutaneous leishmaniasis (CL) is among the top 10 infectious disease priorities in the world, and the leading cause of morbidity in Iran. The present study was conducted to assess the risk of CL, and to determine some epidemiological features of the disease in endemic areas of Qom Province in Central Iran during 2009 to 2013. Data regarding human cases of the disease were obtained from the Qom Province Health Center, prepared and stored in a spatial database created in ArcGIS10.3. A total of 9 out of 212 Leishmania spp. positive slides taken in 2013 from patients residing in Qom city were examined using molecular methods and the species of Leishmania was identified by PCR-RFLP. Those 9 patients had no history of travel outside the city. Spatial analysis and clustering methods were applied to find major hot spots and susceptible areas for the establishment of novel foci of the disease. Transmission patterns were examined for spatial autocorrelation using the Moran's I statistical application, and for the clustering of high or low values using the Getis-Ord Gi* statistics. During the period of study, a total of 1767 CL cases were passively reported in the area, out of which were 65% males and 35% females. The highest and lowest numbers of cases were reported in 2010 and 2013, respectively. Importantly, 979 cases were reported from urban areas, while the remainder came from rural areas. Leishmania major was detected as the causative agent of CL in the city of Qom. Remarkably, most patients recorded in Qom city were associated with a history of travel to the endemic areas of CL within the province, or to other endemic areas of the disease in Iran. Spatial distribution of CL cases revealed northeastern and southwestern quarters of the city were the major hot spots of the disease (P<0.05). Hot spot and CL transmission risk analysis across the province indicated that more than 40 villages were located in high and very high risk areas of CL transmission. Due to the

Studies have shown that it is necessary to create a database for dental maturity for every population and compare it to others. The present study is the first one for dental development in the Icelandic population the age range being 4-24 years. It will help in forensic dental age estimation and will also help dentists, physicians, anthropologists, archaeologists and other professionals who rely on developmental age assessment in children and adolescents. In this present retrospective cross-sectional study, dental maturity was determined in 1100 Icelandic children and adolescents from orthopantomograms (OPGs). The first 100 were used for a pilot study and the remaining 1000 for the main study. A total of 23 subjects were excluded. The sample consisted of 508 girls and 469 boys from the age of 4-24 years and a dental developmental scoring system was used as a standard for determination of dental maturity stages. A total of 200 OPGs were studied both on the left and right side and the remaining on the right side. Dental maturity was established for all teeth and both genders, when the sample permitted, from the beginning of crown formation to the root apex closure. The Cronbach's Alpha reliability test showed high reliability, R=0.982. Girls in Iceland reach dental maturity root completed (stage 10, Rc) at 17.81 years of age for the maxillary and at 18.47 years for the mandibular teeth. Boys reach dental maturity root completed (stage 10, Rc) at 18.00 years of age in the maxilla and 17.63 in the mandible. There was no significant difference between left and right side (r=0.95-1.00) and there was no gender difference, except in root formation in maxillary and mandibular canines where girls reached root completed earlier than boys. A reliable database has been established in Iceland for tooth development in the age range of 4-24 years, which is compatible with international studies. These results will help forensic odontologists and other professionals to estimate with

Mantle Convection beneath the Aegir Ridge, a Shadow in the Iceland Hotspot

The Iceland Hotspot has produced extensive volcanism spanning much of the ocean basin between Greenland and Norway, forming one of the world's largest igneous provinces. However, an apparent igneous "shadow" in hotspot activity is located at the fossil Aegir Ridge, which formed anomalously thin crust, despite this ridge being near the Iceland hotspot when it was active. The Aegir Ridge accommodated seafloor spreading northeast of present-day Iceland from the time of continental breakup at ~55 Ma until ~25 Ma, at which point spreading shifted west to the Kolbeinsey Ridge. To address the cause of the anomalously thin crust produced by the Aegir Ridge, we use three-dimensional numerical models to simulate the interaction between a mantle plume beneath the Iceland hotspot, rifting continental lithosphere, and the time-evolving North Atlantic ridge system. Two end-member hypotheses were investigated: (1) Material emanating from the Iceland mantle plume was blocked from reaching the Aegir Ridge by the thick lithosphere of the Jan Mayen Microcontinent as the Kolbeinsey Ridge began rifting it from Greenland at ~30 Ma, just east of the plume center; (2) Plume material was not blocked and did reach the Aegir Ridge, but had already experienced partial melting closer to the hotspot. This material was then unable to produce melt volumes at the Aegir Ridge comparable to those of pristine mantle. To test these hypotheses, we vary the volume flux and viscosity of the plume, and identify which conditions do and do not lead to the Aegir Ridge forming anomalously thin crust. Results show that the combination of plume material being drawn into the lithospheric channels beneath the Reykjanes Ridge and Kolbeinsey Ridge after their respective openings, and the impedance of plume flow by the Jan Mayen Microcontinent (hypothesis 1), can deprive the Aegir Ridge of plume influence. This leads to low crustal thicknesses that are comparable to those observed. We have yet to produce a model

The purpose of this study was to investigate the relationship between language knowledge at 5 years of age and later academic achievement throughout compulsory school in Iceland. Between 1997 and 1998, 267 Icelandic preschool children aged from 5;4 (years;months) to 5;10 were tested with the HLJÓM-2 (an Icelandic test of phonological awareness; Símonardóttir, Einarsdóttir, & Björnsdóttir, 2002) and the Icelandic version of the Test of Language Development-Primary: Second Edition (TOLD-2P; oral comprehension tasks; Símonardóttir, Guðmundsson, Skúlason, & Pétursdóttir, 1995). In 2011 these individuals, now aged 18-19 years, were contacted again. Of the original 267 participants, 221 (83%) gave permission to link their results from the preschool language assessments with their performance on national tests in 4th, 7th, and 10th grades. The results showed strong correlation between phonological awareness (as measured by the HLJÓM-2) and academic achievement (Icelandic and mathematics) in 4th, 7th, and 10th grades. There was also a significant but lower correlation with oral comprehension skills, as measured with the TOLD-2P. Regression analysis showed that the preschool oral-language assessments in phonological awareness and oral comprehension explained between 35% and 43% of variability in scores on national tests in Icelandic and between 20% and 39% of variability in scores in mathematics. Preschool language knowledge is a reliable predictor of later academic achievement.

This study is a research on uranium and thorium exploration by use of the petrography, petrology and radiometric data in the Saghand area, Central Iran plateau. The lithologies of this area comprise of granite and metasomatized granite. As a result of metasomatic process, uranium and thorium bearing minerals such as davidite and alanite were formed. Sericitization and albitization are the main alterations detected in the study area and thorium mineralization is more common in albitization. By investigation of the chemical classification, non-radioactive specimens, rock types include: diorite and granodiorite, while radioactive specimens consist of gabbroic rocks (basalt). According to the magma source graphs, these rocks formed by calc-alkaline series magma. A scintillometer and spectrometer (MGS-150) were used for radiometric data acquisition. 1001 data points have been obtained from 11 profiles and total counts for, K, U, Th were measured. After primary data processing, data logarithms were calculated for normalizing, and the radiometric data show that uranium and thorium enrichment is more than potassium, while thorium and uranium enrichment are approximately equal. After data integration, two probable anomalies were determined in northwest and northeast parts of the study area. (author)

Interactions between mafic eruptions and glacial ice or snow: implications of the 2010 Eyjafjallajökull, Iceland, eruption for hazard assessments in the central Oregon Cascades

Science.gov (United States)

McKay, D.; Cashman, K. V.

2010-12-01

The 2010 eruption of Eyjafjallajökull, Iceland, demonstrated the importance of addressing hazards specific to mafic eruptions in regions where interactions with glacial ice or snow are likely. One such region is the central Oregon Cascades, where there are hundreds of mafic vents, many of which are Holocene in age. Here we present field observations and quantitative analyses of tephra deposits from recent eruptions at Sand Mountain, Yapoah Cone, and Collier Cone (all advance, which lasted from ~2 to 8 ka in the central Oregon Cascades (Marcott et al., 2009). During the Neoglacial, winter snowfall was likely ~23% greater and summer temperatures ~1.4°C cooler than present (Marcott, 2009). Although ice did not advance to the elevation of the Sand Mountain vents during this time, the eruption could have occurred through several meters of snow. We have also seen very fine-grained tephra at Yapoah Cone, which is located at a higher elevation and may have interacted with glacial ice. In addition to being characterized by unusually fine grainsize, the Yapoah tephra blanket is deposited directly on top of hyaloclastite in several locations. Tephra from Collier Cone is not characterized by unusually fine grainsize, but several sections of the deposit exhibit features that suggest deposition on top of, or interbedding with, snow that later melted away. Identification of features in mafic tephra that suggest interactions with glacial ice or snow has significant implications for regional volcanic hazard assessments. Specifically, the unique hazards posed by Eyjafjallajökull, especially hazards to air travel caused by unusually fine-grained tephra, could be repeated in the Cascades. Although glacial ice is presently limited to elevations above ~2300 m in the central Oregon Cascades, winter snowpack can exceed 5 m at elevations of ~1800 m and above. If a cinder cone eruption were to occur during winter months, interaction with snow could generate phreatomagmatic activity and

The involvement of family in child protection cases in Iceland

Full Text Available The aim of this study is to examine the involvement of families in child protection cases in Iceland, as well as to shed light on the attitudes of child protection workers on the importance of including families while working on child protection cases. The study is part of an international comparative analysis called: Social Work with Families: Social Workers’ Constructions of Family in Professional Practice. This article only addresses the Icelandic segment of the research. In the study, qualitative methods were used and three focus groups were conducted, in which the same three-step vignette about a child protection case was presented. The findings highlighted how difficult child protection workers found it to define the family. The main element is that family are those individuals closest to the child and connected to them through emotional ties, as Icelandic child protection workers seem to strive to involve family in child protection cases. However, there are signs which show that when working with more complicated cases the definition of a family becomes narrower, and involvement is restricted mostly to parents and grandparents. The findings also show that attitudes toward fathers differ from those toward mothers. The mother is expected to support and create security for the child, while the father is judged mostly on his violent behaviour and is not automatically regarded as providing support or actively taking responsibility for his child.

Temperature of the Icelandic crust: Inferred from electrical conductivity, temperature surface gradient, and maximum depth of earthquakes

Science.gov (United States)

Björnsson, Axel

2008-02-01

Two different models of the structure of the Icelandic crust have been presented. One is the thin-crust model with a 10-15 km thick crust beneath the axial rift zones, with an intermediate layer of partially molten basalt at the base of the crust and on the top of an up-domed asthenosphere. The thick-crust model assumes a 40 km thick and relatively cold crust beneath central Iceland. The most important and crucial parameter to distinguish between these different models is the temperature distribution with depth. Three methods are used to estimate the temperature distribution with depth. First, the surface temperature gradient measured in shallow wells drilled outside geothermal areas. Second, the thickness of the seismogenic zone which is associated with a 750 °C isothermal surface. Third, the depth to a layer with high electrical conductivity which is associated with partially molten basalt with temperature around 1100 °C at the base of the crust. Combination of these data shows that the temperature gradient can be assumed to be nearly linear from the surface down to the base of the crust. These results are strongly in favour of the thin-crust model. The scattered deep seismic reflectors interpreted as Moho in the thick-crust model could be caused by phase transitions or reflections from melt pockets in the mantle.

Economical impact of plasma fractionation project in Iran on affordability of plasma-derived medicines.

Cheraghali, A M; Aboofazeli, R

In Iran all transfusion services are concentrated under authority of one public and centralized transfusion organization which has created the opportunity of using plasma produced in its blood centers for fractionation. In 2008 voluntary and non remunerated Iranian donors donated 1.8 million units of blood. This indicates a 25/1000 donation index. After responding to the needs for fresh plasma and cryoprecipitate each year about 150000 L of recovered plasma are reserved for fractionation. In an attempt to improve both blood safety profile and availability and affordability of plasma derived medicines, Iran's national transfusion service has entered into a contract fractionation agreement for surplus of plasma produced from donated blood by voluntary non remunerated donors. In order to ensure safety of product produced, Iran has chosen to collaborate with international fractionators based in highly regulated countries. The main objective of this study was to evaluate the impact of contract plasma fractionation on the affordability of the plasma derived medicines in Iran. During 2006-2008, Iran's contract fractionation project was able to produce 46%, 18% and 6% of IVIG, Albumin and FVIII consumed in Iran's market, respectively. In contrary to IVIG and Albumin, due to fairly high consumption of FVIII in Iran, the role of fractionation project in meeting the needs to FVIII was not substantial. However, Iran's experience has shown that contract plasma fractionation, through direct and indirect effects on price of plasma derived medicines, could substantially improve availability and affordability of such products in national health care system.

Application of subsurface temperature measurements in geothermal prospecting in Iceland

Flóvenz, Ólafur G.

In geothermal areas in Iceland aquifers are in most cases found to occur in highly permeable near-vertical fractures in the low permeability basaltic crust. Therefore heat transfer in the rocks surrounding the aquifers is mainly conductive. Temperature profiles in shallow non-flowing boreholes are used to construct a two dimensional model of the temperature distribution in the vicinity of near vertical aquifers. This is done by finite element solution of the equation of heat transfer which requires knowledge of the regional temperature gradient outside the area of geothermal activity and some constraints on the temperature within the aquifers. The model is helpful in estimating dip and location of near-vertical water bearing fractures and thus in siting production wells. An example of successful use to the method and of soil temperature measurements from a geothermal field in North-Iceland is demonstrated.

In this paper the literature on helminthiasis in Iran is reviewed and the distribution, prevalence and intensity of infections caused by helminths are discussed. A comparison of prevalence and intensity of infections was accomplished in the recent 10 years by the author. Hookworm infections are found mostly in the north along the Caspian sea, but its prevalence is declining. Trichostrongylus are found in Iran with a high prevalence in central country. Schistosoma haematobium is found in one Province in the south, but its prevalence is declining because of large scale control activities. The Guinea worm rarely occurs in Iran. The prevalence of Fasciola hepatica is high among livestock and is occasionally found in man. Taenia saginata is found in most parts of Iran. Taenia solium is seldom found in animals with a prevalence of 0.03%. Trichinella spiralis is infrequently found in animals. Dioctophyma renale is found in straying dogs in the north or Iran, the percentage is 13-35%. Oxyuriasis is widespread among children.

CITY, COUNTRYSIDE AND NATURE AS DISCURSIVE DEVICES USED TO STRENGTHEN THE NATIONAL IDENTITY IN ICELANDIC CINEMATOGRAPHY

Directory of Open Access Journals (Sweden)

Jakub Sebastian Konefał

2015-03-01

Full Text Available Since its inception the Icelandic film industry has used the strategy of combining telluric elements with national- istic narratives. In many films one may also find visual structures that can be linked with the ‘tourist gaze’ – the term as we know it from the texts of John Urry. Despite a focus on some unique qualities of Icelandic nature and its cultural heritage (that can be attractive to foreign viewers the specificity of cinematic production processes on the island belong to the structure of local, national cinema. Moreover, the 1980s, considered as the time of the rebirth of the Icelandic film industry and its rapid modernization, are full of films containing conservative or leftist telluric topics which are difficult for foreign audiences to understand. A new, transnational quality of Icelandic film features began with the film debut of Friðrik Þór Friðriksson in 1987. His fusion of modernist and postmodernist plots has encouraged other filmmakers to start the process of re-interpretation of the classic narrative structures, and to render the ironic demystification of some nationalistic themes.

Money Talks: Gender Budgeting in the University of Iceland

Full Text Available The article addresses the financial framework, decision-making and budgeting processes of the University of Iceland from a gender perspective. The newly appointed rector of the University of Iceland (elected 2015 together with the university council is currently revising the UI system of the distribution formula of budget allocation. This provides an opportunity to examine the system which is inspired by New Public Management, with emphasis on global competition and performance based indicators. The aim of the article is to scrutinize the current system of budget allocation and distribution and its significance when it comes to gender. We ask how the, allegedly gender neutral, system plays out for different schools and disciplines and for academics in different ranks, when the gender dimension is taken into account. We draw on empirical data collected as part of the GARCIA research project, Gendering the Academy and Research combating Career Instability and Asymmetries, which is supported by the 7th Framework Programme of the European Union. To shed a light on the process we focus on the male-dominated School of Engineering and Natural Sciences (SENS and the more feminised School of Social Sciences (SSS. The exploration shows that the financial framework, decision-making and budgeting processes at the University of Iceland are rather non-transparent, and biased in favour of the natural sciences. This applies to funding from the state; third party funding; the allocation of funding in the teaching part of the budgeting, as well as the research part. From the article it can be concluded that the current system contains an internal, though unintended, gender bias that needs to be corrected.

Iran: spotlight.

Roudi, N

Given its location between Asia and Asia Minor, Iran has been a country of strategic political importance throughout history. More than 98% of Iran's population is Moslem. During the early 20th century, as Iran gradually gained independence from the USSR and Turkey, a modernization process was begun. However, this modernization process was forced to yield to Islamic traditionalism after the 1979 Islamic Revolution. Women have been most affected by this change. The implementation of Islamic traditions has meant low job opportunity or motivation for continuing education among women. Although fertility remains high, the present government is satisfied with the current rate of population growth. Family planning is allowed if implemented within the framework of Islamic law, but abortion is illegal. Mortality fell substantially after World War II, but has not continued to decline. At present, both males and females have the same life expectancy at birth. Iran's population is growing at a rate of 4%/year, and can be expected to double in another 21 years. It has been projected that Iran, currently the 21st largest country in the world with a population of 50 million, will become the 15th largest with a population of 97 million by the year 2025. Tehran, the 20th largest city in 1985, is projected to be the 9th largest by the year 2000, with a population of 13.6 million.

Imaging magma plumbing beneath Askja volcano, Iceland

Science.gov (United States)

Greenfield, Tim; White, Robert S.

2015-04-01

Volcanoes during repose periods are not commonly monitored by dense instrumentation networks and so activity during periods of unrest is difficult to put in context. We have operated a dense seismic network of 3-component, broadband instruments around Askja, a large central volcano in the Northern Volcanic Zone, Iceland, since 2006. Askja last erupted in 1961, with a relatively small basaltic lava flow. Since 1975 the central caldera has been subsiding and there has been no indication of volcanic activity. Despite this, Askja has been one of the more seismically active volcanoes in Iceland. The majority of these events are due to an extensive geothermal area within the caldera and tectonically induced earthquakes to the northeast which are not related to the magma plumbing system. More intriguing are the less numerous deeper earthquakes at 12-24km depth, situated in three distinct areas within the volcanic system. These earthquakes often show a frequency content which is lower than the shallower activity, but they still show strong P and S wave arrivals indicative of brittle failure, despite their location being well below the brittle-ductile boundary, which, in Askja is ~7km bsl. These earthquakes indicate the presence of melt moving or degassing at depth while the volcano is not inflating, as only high strain rates or increased pore fluid pressures would cause brittle fracture in what is normally an aseismic region in the ductile zone. The lower frequency content must be the result of a slower source time function as earthquakes which are both high frequency and low frequency come from the same cluster, thereby discounting a highly attenuating lower crust. To image the plumbing system beneath Askja, local and regional earthquakes have been used as sources to solve for the velocity structure beneath the volcano. Travel-time tables were created using a finite difference technique and the residuals were used to solve simultaneously for both the earthquake locations

Inter-Rifting and Inter-Seismic Strain Accumulation in a Propagating Ridge System: A Geodetic Study from South Iceland

Travis, M. E.; La Femina, P. C.; Geirsson, H.

2012-12-01

The Mid-Atlantic Ridge, a slow spreading (~19 mm/yr) mid-ocean ridge boundary between the North American and Eurasian plates, is exposed subaerially in Iceland as the result of ridge-hotspot interaction. Plate spreading in Iceland is accommodated along neovolcanic zones comprised of central volcanoes and their fissure swarms. In south Iceland plate motion is partitioned between the Western Volcanic Zone (WVZ) and Eastern Volcanic Zone (EVZ). The EVZ is propagating to the southwest, while the WVZ is dying out from the northeast. Plate motion across both systems has been accommodated by repeated rifting events and fissure eruptions. In this study we investigate whether the WVZ is active and accumulating strain, and how strain is partitioned between the WVZ and EVZ. We also test how strain is accumulating along fissure swarms within the EVZ (i.e. is strain accumulation localized to one fissure swarm, or are multiple systems active?). We use GPS data and elastic block models run using the program DEFNODE to investigate these issues. GPS data are processed using the GIPSY-OASIS II software, and have been truncated to the 2000.5-2011 time period to avoid co-seismic displacement from the two June 2000 South Iceland Seismic Zone earthquakes. We also truncate the time series for sites within 20 km of Eyjafjallajökull to the beginning of 2010 to eliminate deformation associated with the March 2010 eruption of that volcano. We correct for co-seismic displacement from the two May 2008 SISZ earthquakes, inflation at Hekla volcano and the horizontal component of glacial isostatic rebound (GIA). Our best-fit model for inter-rifting and inter-seismic elastic strain accumulation suggests 80-90% of spreading is accommodated in the EVZ with the other 10-20% accommodated by the WVZ. The best-fit location of the EVZ is between Veidivotn and Lakigigar in an area of no Holocene volcanic activity. We suggest the WVZ is only active at Hengill and its associated fissure swarm.

Background Cryptogenic organising pneumonia (COP) has also been called idiopathic bronchiolitis obliterans organising pneumonia. In secondary organising pneumonia (SOP) the causes can be identified or it occurs in a characteristic clinical context. The aim of this study was to determine the incidence and epidemiological features of COP and SOP nationwide in Iceland over an extended period. Methods A retrospective study of organising pneumonia (OP) in Iceland over 20 years was conducted and the epidemiology and survival were studied. All pathological reports of patients diagnosed with or suspected of having COP or SOP in the period 1984–2003 were identified and the pathology samples were re‐evaluated using strict diagnostic criteria. Results After re‐evaluation, 104 patients fulfilled the diagnostic criteria for OP (58 COP and 46 SOP). The mean annual incidence of OP was 1.97/100 000 population (1.10/100 000 for COP and 0.87/100 000 for SOP). The mean age at diagnosis was 67 years with a wide age range. The most common causes of death were lung diseases other than OP, and only one patient died from OP. Patients with OP had a lower rate of survival than the general population, but there was no statistical difference between COP and SOP. Conclusions The incidence of OP is higher than previously reported, suggesting that OP needs to be considered as a diagnosis more often than has been done in the past. PMID:16809413

Injuries and deaths from road traffic crashes are one of the main public health problems throughout the world. This study aimed to identify determinants of fatality traffic accident in Iran for the twenty-span year from 1991 to 2011. A time series analysis (1991-2011) was used to examine the effects of some of the key explanatory factors (GDP per capita, number of doctors per 10,000 populations, degree of urbanization, unemployment rate and motorization rate) on deaths from road traffic in Iran. In order to examine long- and short-run effects of variables, we employed autoregressive distributed lag (ARDL) approach and error correction method (ECM). The data for the study was obtained from the Central Bank of Iran (CBI), Iranian Statistical Center (ISC) and Legal medical organizations (LMO). GDP per capita, doctor per 10,000 populations, degree of urbanization and motorization rate had a significant impact on fatality from road traffic in Iran. We did not observe any short- and long-term effects of the unemployment rate on fatality from road traffic. GDP per capita, doctor per 10,000 populations, degree of urbanization and motorization rate were identified as main determinant of fatality from road traffic accidents in Iran. We hope the results of the current study enable health policy-makers to understand better the factors affecting deaths from road traffic accidents in the country.

Gender and spatial population mobility in Iran.

Hemmasi, M

1994-01-01

1976-1986 data from the National Census of Population and Housing were analyzed to examine the spatial patterns of internal migration of women and men in Iran within its Islamic patriarchal cultural system. The researcher also organized 1986 data into two interprovincial migration matrixes for men and women. Women were spatially as mobile as men (urban, 16.7% for men and 17% for women; rural, 8.4% and 8.9%, respectively). Gender spatial mobility patterns during the 10 years included: migration streams from nine provinces consistently led to Tehran province, most migration flows to Tehran and most other provinces originated from Khuzistan, East Azerbaijan province still continued to lose population (about 500,000), and out-flows generally originated from the provinces affected by the Iran-Iraq war and went to the central and eastern provinces. The strongest determinants of women's migration was men's migration ratio and the road distance between the origin and destination. Reasons for these strong associations were few employed women ( 10%), strong family ties, and traditional cultural values (e.g., women tend not to travel alone). So their migration patterns tended to be associational rather than autonomous. Despite the fact that internal migration patterns of men and women were the same, the causes, processes, and consequences of migration were still very gender-specific in Iran. There are no signs of change in the near future.

The present study was carried out to determine the sub-assemblages of G. lamblia isolated from food handlers referred to Kashan health centers, central Iran, 2015.Methods: In this cross-sectional study, 3653 stool samples collected from food-handlers that annually refer to health center for getting a health certification and examined microscopically for G. lamblia cyst. Totally, 44 isolates were selected from 47 Giardia positive samples. Cysts were partially purified by the sucrose density gradient method. After freeze-thaw cycles, genomic DNA was extracted using QIAamp Stool Mini kit. A single step PCR-RFLP method was used to amplify a 458bp fragment at the glutamate dehydrogenase (gdh locus, restriction enzymes BspLI and RsaI were used for distinguish between genotypes A and B and their subgroups.Results: Of 44 isolates, 24(54.5% were sub-assemblage AII, 9(20.5% group B including 7(15.9% BIII and 2(4.6% BIV sub-assemblage and 11(25% isolates showed a mixed pattern of AII and B. Sub-assemblage AI was not detected in this study.Conclusion: The higher rate of sub-assemblage AII demonstrated an anthroponotic origin of the infection so infected food-handlers could directly transmit this protozoan to consumers via contaminated food and water. For finding of pattern of transmission and distribution of Giardia assemblages and sub-assemblage, more studies in human and animal population in different regions are necessary.

Energy projects in Iceland – Advancing the case for the use of economic valuation techniques to evaluate environmental impacts

International Nuclear Information System (INIS)

Cook, David; Davíðsdóttir, Brynhildur; Kristófersson, Daði Már

2016-01-01

Decision-making in Iceland has occurred without reference to economic valuations of the environmental impacts of energy projects. Environmental Impact Assessments, a legal requirement for nearly all energy projects in Iceland since 1994, have played an important role in identifying the environmental impacts of energy projects, and proposing mitigation measures. However, a purely qualitative description of environmental impacts is insufficient to ensure that they are accounted for equivalently with all of the other costs and benefits of a proposed project. Instead, as monetary information concerning the welfare gains or losses of proposed projects is not currently required to be provided to the licensing body, Orkustofnun, there is the potential for sub-optimal decision-making to occur. As this paper sets out, a broad variety of non-market valuation techniques already exist and could be applied to estimate the value of environmental benefits sacrificed to accommodate such developments. These methods and their outcomes could be incorporated within mandatory cost-benefit assessments for proposed Icelandic energy projects, communicating an estimate of the full welfare implications of approvals to decision-makers and the public alike, and fulfilling an OECD demand for the country to commence such processes. - Highlights: •Current risk of sub-optimal decision-making by licensing body, Orkustofnun. •OECD call for monetary valuations of environmental impacts linked to Icelandic energy projects. •Lessons to be learned from US regulatory approach to advance cost-benefit assessment practice in Iceland. •Practice of conducting non-market valuation techniques limited in Iceland, but now growing.

Smoking is related to health deterioration through increased risk of various diseases. Changes in this health behavior could contribute to the documented health improvements during economic downturns. Furthermore, the reasons for changes in behavior are not well understood. We explore smoking behavior in Iceland before and after the sudden and unexpected economic crisis in 2008. Furthermore, to explore the mechanisms through which smoking could be affected we focus on the role of labor-market changes. Both real income and working hours fell significantly and economic theory suggests that such changes can affect health behaviors which in turn affect health. We use individual longitudinal data from 2007 to 2009, incidentally before and after the crisis hit. The data originates from a postal survey, collected by The Public Health Institute in Iceland. Two outcomes are explored: smoking participation and smoking intensity, using pooled ordinary least squares (OLS) and linear probability models. The detected reduction in both outcomes is not explained by the changes in labor-market variables. Other factors in the demand function for tobacco play a more important role. The most notable are real prices which increased in particular for imported goods because of the devaluation of the Icelandic currency as a result of the economic collapse.

Iran is viewed by many as a rising power that poses an increasing threat to regional and even global security. This view is wrong for three reasons. Iran's hard and soft power is exaggerated by most accounts; it is too limited to allow the Iranians to dominate the Persian Gulf let alone the Middle...... East, and its brand of Shi‘ism has very limited appeal outside of Iran. Second, growing internal political and economic instability will seriously limit Iran's bid for regional dominance. Third, the failure to stop the Iranian nuclear program has led analysts to underestimate the ability of the other...... regional powers and the West to balance Iran and contain its influence, even if it acquires nuclear weapons. If these limitations on Iranian power are taken into account the rise seems destined to be a short one....

Palliative care focuses on improving quality of life (QoL). This study examined the feasibility of the Icelandic version of a provisional European Organisation for Research and Treatment of Cancer (EORTC) measure of spiritual well-being (SWB), and explored the relationship between SWB and QoL for palliative care patients in Iceland. Instruments from the EORTC were used: the provisional measure of SWB, which was undergoing pilot-testing in Iceland, and the EORTC QLQ C15-PAL. The correlation between scores was examined and descriptive statistics were used. Structured interviews explored feasibility. Thirty persons participated with average age 72 years. Belief in God or a higher power had the mean 3.33 on a 1-4 scale and the mean for overall SWB was 5.73 on a 1-7 scale. The mean score for global health/QoL was 59.4, physical functioning 48.5 and emotional functioning 78.9 on a 0-100 scale. Overall QoL was positively correlated with SWB showing r(30) = 0.386, P = 0.035. The participants found that answering the provisional EORTC QLQ-SWB prompted an emotional response and took the opportunity to discuss the subject. The provisional SWB measure was found relevant for the Icelandic context, and the study indicates that SWB and QoL are closely connected. © 2015 John Wiley & Sons Ltd.

Iran irritates and puzzles the world

In this paper author analyses political and economic situation in the Iran. Iran is endangered by economic sanctions and military attacks on nuclear facilities, the president threatens by retributive military attacks. Situation in Iran is compared with Iraq. Perspectives of application of political and economic embargo against Iran are discussed. USA and co-adjuster would probably meet the Russian or Chinese veto. On the international markets or on the bilateral level the good volition to disable to Iran the sale of its oil and natural gas would by scarcely expected. Iran exports from 2.5 to 3 million barrels of oil daily. It is impossible to substitute Iran essentially. The country is the fourth biggest exporter of oil in the world and has the second biggest stocks of oil after Saudi Arabia. Iran is endangered by the fact that big question mark will stay to hang above nuclear program. The part of uranium is imported from African countries like Gabon and Niger through France and the sanctions of UN would stop this import. Iran has its own uranium fields, even which belongs to the largest in the world. However, Iran cannot exploit them effectively without help of western companies. Nuclear program, which is supported by big hope and sources from the country, probably collide with unexpected barriers. Even if UN Safety Council would not confirmed anti-Iran sanctions, the seven states that produce nuclear technologies would stop their sale to Iran. It would freeze its civilian and military nuclear program from a few years or some decades

[History of acupuncture in Iran].

Iran is the neighbor of western China, and is a key transport junction on ancient Silk Road. The medical communication between China and Iran dates back to the 10th century, however, according to current evidences, it is indicated that acupuncture has not been introduced to Iran until the early 1970s. Unfortunately over the last 40 years, the acupuncture in Iran has not presented great development. The history of acupuncture development in Iran implies that geographical advantage and personnel exchanges are not essential to the international exchange of acupuncture, while language and cultural background may hinder the spread of acupuncture in foreign countries.

Greenland's largest flux of precipitation occurs in its Southeast (SE) region. An understanding of the mechanisms controlling precipitation in this region is lacking despite its disproportionate importance in the mass balance of Greenland and the consequent contributions to sea level rise. We use weather station data from the Danish Meteorological Institute to reveal the governing influences on precipitation in SE Greenland during the winter and fall. We find that precipitation in the fall is significantly correlated to the longitude of the Icelandic Low and the NAO. Winter precipitation is correlated with the strength and longitude of the Icelandic Low, as well as the NAO. We show that in years of extreme high precipitation, onshore winds dominate, thereby advecting more moisture inland. In low precipitation years, winds are more westerly, approaching the stations from land. Understanding the controls of SE Greenland precipitation will help us predict how future precipitation in this key region may change in a warming climate.

The FUTUREVOLC volanological supersite will establish a data hub and dataservice, where researchers, hazard managers and other stake holders can freely obtain access to multidisciplinary data and products on activity, unrest and eruptions at Icelandic volcanoes. The supersite is firmly founded on close interaction between the main Icelandic volcanological research and monitoring institutions, in coordination with expertise from European researchers participating in FUTUREVOLC. The hub is located at the Icelandic Meteorological Office (IMO), an institution responsible for monitoring and archiving data on all natural hazards in Iceland and, which also has a mandate as the state volcano observatory. This association will ensure a long-term sustainable data service. The data accessible at the hub include in-situ and space-based observations, products and models from all the relevant disciplines contributing to volcanological research and local as well as cross-border hazard management, i.e. Earth sciences, atmospheric science, hydrology, remote sensing and space science. Access to the data will be in compliance with the access policy of the GEO (Group on Earth Observations), providing registered users with easy and timely access to data and products of documented quality. This commitment has already led to the acceptance of FUTUREVOLC as a permanent geohazard supersite by CEOS (Committee on Earth Observation Satellites), which will ensure access to additional satellite data and products on Icelandic volcanoes. To facilitate services to seismological data at the supersite hub, the IMO is reconstructing its existing data base and utilizing the SeisComp3 software to manage waveform and parameter data. The accompanying ArcLink component will be used to provide access to event data and waveforms. Access to GPS data will be provided by the GSAC web service which has been installed at the IMO through collaboration with UNAVCO. If appropriate, the format and data base

Full Text Available Diversification of production by including a broader range of plant species, can significantly contribute to improve health and nutrition, livelihoods, household food security and ecological sustainability. Exploring the climate impact on any given crop is one of the first priorities to find new suitable areas for production and management of new crops. Summer squash (Cucurbita pepo L. is an economically valuable plant with various medicinal potentials. In order to investigate summer squash cultivation feasibility under Irans climate, three main agricultural regions (Azerbaijan, Khorasan and central part of Iran (Fars and Isfahan were selected. These regions suitability for summer squash cultivation were evaluated by considering three vital climate variables encompass temperature, precipitation, and sunshine hours. These regions show distinct and representative climatic conditions of Iran. Annual and growing season average of maximum, minimum, mean temperature, precipitation, and sunshine hours were calculated (May-September for all locations with 44 years historical weather data (1961-2005 for 8 locations (Oroomieh, Tabriz, Khoy, Mashhad, Sabzevar, Birjand, Shiraz and Isfahan, 39 years (1966-2005 for 2 locations (Kashan and Fassa, 28 years (1977-2005 for 4 locations (Ardebil, Abadeh, Bojnurd and Shargh Isfahan and 20 years (1985-2005 for 9 locations (Mahabad, Sarab, Maragheh, Parsabad, Khalkhal, Ferdous, Ghaen, Kashmar and Sarakhs. Climatic demands of summer squash were determined by four years field studies at four different locations in Iran. Our results showed Azerbaijan region has a suitable condition for this crop cultivation especially from precipitation and temperature perspectives. Central part of Iran and Khorasan were also found as partly suitable locations however as they are near to deserts with hotter and drier climate, there might be some other crops considered as priorities in these areas.

Iran's 'Risk-Taking' in Perspective

International Nuclear Information System (INIS)

Shahram, Chubin

2008-01-01

Assessing any state's intentions is a difficult undertaking - especially at a specific moment in time. When a state is considered hostile, its behaviour erratic, and its system opaque, what is difficult under normal circumstances becomes nearly impossible. It may thus often seem prudent to attribute the worst of intentions to such states, but this can create a self-fulfilling prophecy. Iran with its revolutionary pretensions, fiery rhetoric and nuclear ambitions, is a case in point, since it is particularly difficult to 'read'. Located in the centre of a geo-politically sensitive and conflict-driven area, Iran is in a position to influence - positively or otherwise - the Persian Gulf, the Caucasus, the Middle East and South Asia. This influence may furthermore be expanding as a result of the weakening of Iraq and Lebanon, divisions among the Palestinians, and the more general rise of the Shi'i across the broader region. Add to this the ambiguous aims of Iran's nuclear programme and the shadow this has already thrown across the region, and the need to assess Iran's intentions accurately appears crucial. Here, Iran's past behavior may provide some help, especially when it comes to Iran's proclivity for risk taking - provided the acquisition of a nuclear capability does not alter Iran's intentions or behavior so as to make the past irrelevant. Some commentators believe that Iran's ideology and past behaviour suggest that a nuclear-capable Iran will be inclined to take on a high level of risk, without concern for the potential costs of this recklessness, and that Iran may perhaps even welcome the risks involved. By contrast, the recent National Intelligence Estimate (NIE), a composite of US intelligence agency estimates, has concluded that Iran's 'decisions are guided by a cost-benefit approach' and therefore 'may be more vulnerable to influence' than they had previously (i.e.2005) judged. These divergent views broadly reflect the division between those who believe

Preferences, power and policy outcomes in public policy in Iceland: The Icelandic Housing Fund fiasco 2003-2005

Directory of Open Access Journals (Sweden)

Sigurbjörg Sigurgeirsdóttir

2014-12-01

Full Text Available This research focuses on the interplay of politics, bureaucracies and markets in Iceland. It aims to explain theoretically how politics and bureaucracies operate when a coalition government makes and implements decisions in a policy environment in which decisions and their effects intersect public bureaucracies’ and markets’ boundaries. The decision to raise the limits of Housing Fund mortgages in 2003 is a case examined by agenda-setting theories in public policy. The research is based on the data from parliamentary Special Investigation reports on the collapse of the Icelandic banks and the Housing Fund as well as the author’s interviews home and abroad. The research shows that, when made, the decision ignited competition between the Housing Fund and the recently privatized banks and that between the banks themselves. The Independence Party’s attempts to delay implementation of the decision involved system change backed by an instrument designed to stem a run on the Fund. The impact of this instrument (a tax on pre-payments was incompatible with the Progressive Party’s political interests. In a hasty attempt to implement its election promises, the Progressive Party ignored the fact that the Fund was operating within a transformed financial system. The conclusions indicate that those who think long-term in politics make policies by changing system dynamics, those who think short-term change programmes. System dynamics, however, change the balance of power and influence between actors, leaving legacies which curb the government’s attempt at change, unless consolidated and sustained political authority and will are established to see changes through.

Geographical, and seasonal variation in the diet of harbour porpoises (Phocoena phocoena in Icelandic coastal waters

Directory of Open Access Journals (Sweden)

Gísli A Víkingsson

2003-07-01

Overall capelin (Mallotus villosus comprised the predominant prey, followed by sandeel (Ammodytidae sp., then gadids, cephalopods and redfish (Sebastes marinus, while other taxa were of less importance. Differences were detected in diet composition among 5 areas around Iceland with redfish and gadids more prominent in the northern areas. Off SW Iceland there was considerable seasonal variation in the porpoise diet, where capelin appeared to be dominant in late winter and spring and sandeel in the summer through early winter. Predominance of capelin in the diet coincided with the spawning migration of capelin from northern waters along the east, south and west coasts of Iceland. Mature females appeared to have a more diverse diet than other reproductive classes. The length distributions of fish consumed by the porpoises ranged from 1 to 51 cm although most fish prey were less than 30 cm.

This paper provides arguments for a multi-advance model of Weichselian glaciation-deglaciation of Northern Iceland considering the influence of the geothermal gradient and of the ice sheds on the different ice-stream outlets. This paper is based on morphological mapping , SPOT images analysis high resolution stratigraphy, palaeopedology, tephra petrography and Ar/K dating. The Last Glaciation Maximum has a limited extend in Northern Iceland, with cold-based characteristics, except in sectors of high thermal gradient which supported low profile ice streams, a main difference with MIS6. Ice sheet building started from MIS 5d with a limited extent. At MIS 5b the thickness of the ice is enough to enable the activity of the eastern hyalocastite ridge in the NVZ. The maximal extent is reached abruptly at the boundary stage 3/2, probably in relation with increased precipitation, with development of H3, followed by a drastic retreat, controlled by very low precipitation rate and cold-based glaciers. This period is responsible for long periglacial morphogenesis inland, on the nunataks and ice free areas, and for starved sedimentation on the shelf and in the fjords. From 17 ka or H2, precipitation rose again and a second maximal extent, the Fnjoskadalur Stadial, the so-called "Old Dryas", in retreat from the former one. The main deglaciation took place at the onset of the Bölling. A late glacial pulse of minimal intensity occurred with the Younger Dryas. The Pre-Boreal stadial is extremely limited in the North of Iceland in relation with the lower and colder conditions compared to the south coast inflenced by the Irminger current.

Is earthquake rate in south Iceland modified by seasonal loading?

Science.gov (United States)

Jonsson, S.; Aoki, Y.; Drouin, V.

2017-12-01

Several temporarily varying processes have the potential of modifying the rate of earthquakes in the south Iceland seismic zone, one of the two most active seismic zones in Iceland. These include solid earth tides, seasonal meteorological effects and influence from passing weather systems, and variations in snow and glacier loads. In this study we investigate the influence these processes may have on crustal stresses and stressing rates in the seismic zone and assess whether they appear to be influencing the earthquake rate. While historical earthquakes in the south Iceland have preferentially occurred in early summer, this tendency is less clear for small earthquakes. The local earthquake catalogue (going back to 1991, magnitude of completeness M6+ earthquakes, which occurred in June 2000 and May 2008. Standard Reasenberg earthquake declustering or more involved model independent stochastic declustering algorithms are not capable of fully eliminating the aftershocks from the catalogue. We therefore inspected the catalogue for the time period before 2000 and it shows limited seasonal tendency in earthquake occurrence. Our preliminary results show no clear correlation between earthquake rates and short-term stressing variations induced from solid earth tides or passing storms. Seasonal meteorological effects also appear to be too small to influence the earthquake activity. Snow and glacier load variations induce significant vertical motions in the area with peak loading occurring in Spring (April-May) and maximum unloading in Fall (Sept.-Oct.). Early summer occurrence of historical earthquakes therefore correlates with early unloading rather than with the peak unloading or unloading rate, which appears to indicate limited influence of this seasonal process on the earthquake activity.

Full Text Available Background and Aim: Due to the high prevalence and worldwide distribution of Enterobius vermicularis and its readily transmission among children, parents' knowledge and health education have an important role in restriction and infection control. This study was performed to evaluate the girl students' knowledge about transmission, symptoms, and prevention of oxyuriasis in 2012–2013 in Kashan, Central Iran. Materials and Methods: In this cross-sectional study, a total of 500 students in three levels of middle schools were studied. To evaluate the students' knowledge level of oxyuriasis, the standardized questionnaire was distributed and completed. Data were analyzed using statistical software SPSS. Results: Among three levels of students of middle schools, 67.6% of students had average awareness (information, 17.4% had weak information, and 15% had high information. In the assessment of the level of awareness in the first-level students, 23.41% of the students had weak information, 66.4% had average information, and 10.12% had high information. In the second-level students, 12.57% had weak information, 73.14% had average information, and 14.28% had high information. In the third-level middle-school students, 16.76% of students had weak knowledge, 62.87% had average knowledge, and 20.35% had high knowledge. Conclusion: The result of this study shows that knowledge of middle-school students about this infection is good but not sufficient, and it is necessary for teachers and health officers in schools to increase hygienic knowledge of the students and to train about this infection to decrease the damage of personal and social problems.

Social Media Used by Government Institutions in Iceland: Application, Role and Aims

Full Text Available The purpose of this research was to study the use and role of social media hosted by government institutions in Iceland. The research was conducted using quantitative and qualitative research methods. A survey was sent electronically to all government institutions in Iceland and semi-structured interviews were conducted with specialists working for institutions. No research has been conducted on this subject in Iceland before. It was therefore considered timely that a research was conducted on the use of social media in public institutions, with the intention of adding new knowledge to the field. No similar research from outside of Iceland was found, but this research was based on related studies and sources from abroad. A little less than half of government institutions used social media as part of their activities and Facebook and YouTube were most widely used. Popularity, circulation, usefulness and convenience were the most important factors when choosing social media. The majority of institutions had neither defined social media goals nor the role and responsibility of employees when using social media. The institutions placed strong emphasis on publishing adverts and news items on the institutions’ activities via social media pages and there were a considerable number of references to material on other web pages. Among other things the interviewees said that the purpose of using social media was information dissemination, reception of information, more visibility, the opening of institutions to the public and increased transparency. They talked about the importance of being informal on social media, but they also pointed out that there had been some fear among institutions of using them, in particular fear of employees showing a human side via social media. There was minimal use of original material on institutions’ social media pages, while institutions were quite systematic in posting material from their website through social media

The Iran-1 and Iran-2 nuclear power station on the Persian Gulf

International Nuclear Information System (INIS)

Altvater, W.

1977-01-01

Iran is a country with large oil reserves which, however, are exploited only very carefully because of ther importance for exports. In the light of this policy it was decided to make increasing use of nuclear energy for the country's electricity supply. Under the 8th Iranian five year plan, a total installed generating capacity of 56,000 MW is foreseen by 1993, of which 24,400 MW will be in nuclear power plants. This large construction program of nuclear power stations is implemented by the Atomic Energy Organization of Iran, AEOI, which started negotiations with potent nuclear industries of various industrialized countries in early 1974. In November 1974, these discussions led to a letter of intent with the German Kraftwerk Union AG (KWU) for the turnkey erection of the first Iranian nuclear power plant, Iran-1 and Iran-2, with two units of 1,300 MW on a site on the Persian Gulf. The siting decision was taken in favor of the Halileh area located some 18 km from the seaport of Bushehr. Construction work on the site began in July 1975. The delivery dates are December 1, 1980 for Iran-1 and November 1, 1981 for Iran-2. (orig.) [de

‘Bois noir’: new phytoplasma disease of grapevine in Iran

Directory of Open Access Journals (Sweden)

Mirchenari Seyed Mehdi

2015-01-01

Full Text Available Recently, grapevines showing symptoms suggesting the ‘bois noir’ phytoplasma disease were observed in vineyards located in several central provinces of Iran. Polymerase chain reaction assays using phytoplasma universal primer pair P1A/P7A followed by primer pair R16F2n/R16R2 in nested PCR, confirmed the association of phytoplasmas with symptomatic grapevines. The results of RFLP analyses using HpaII, HinfI, MseI, RsaI, and TaqI restriction enzymes, indicated that grapevine phytoplasma isolates in these regions could be related to the 16SrXII group. Sequence analyses of the partial 16S rRNA gene confirmed that Iranian grapevine phytoplasmas are associated with ‘Candidatus Phytoplasma solani’. This is the first report of the ‘bois noir’ disease outbreak in Iran

Indexation of Consumer and Mortgage Credit in Iceland in 2014: A Critical Battle between Legality, Fairness and Legitimacy

Directory of Open Access Journals (Sweden)

Maria Elvira Mendez Pinedo

2014-11-01

Full Text Available Six years after the financial crisis that led to the collapse of the banking system in 2008, the over-indebtedness of households is one of the most important problems in Iceland. This study aims to cast light on a specific feature of the Icelandic credit system in connection with the problem of over-indebtedness. The main research question is whether the end of indexation of credit is close or not. The author argues, in the first place, that indexation of credit ex-post to the consumer price index (CPI in negative amortization schemes is responsible for over-indebtedness. In the second place, the author describes the challenges ahead in the field of consumer and mortgage credit in Iceland in the light of European law (European Union EU and European Economic Area EEA. The incorporation of Directive 2008/48 on credit agreement for consumers to the Icelandic domestic order through the EEA Agreement allowed a preliminary legal review of the practice in light of EU/EEA consumer credit law, both at national and European level without a final conclusion. It has nevertheless led to the judicial review on the legality of some indexation alleged malpractices before national courts and to the EFTA Court for interpretation (mostly on Directives 93/13/EEC on unfair terms 87/102/EEC on consumer credit. A ruling from the Supreme Court is expected on several cases. A critical battle between the legality, the fairness and the legitimacy of indexation of credit is taking place in Iceland under the influence of European law.

Iceland and Cyber-threats: Is it more than fear of fear?

Directory of Open Access Journals (Sweden)

Jón Kristinn Ragnarsson

2011-06-01

Full Text Available The challenge of cyber-threats is a modern reality from which no state, including Iceland, can hope to escape. Cyber-attacks can cause major damage remotely, at minimal cost and while concealing the culprits. Groups and individuals can carry them out as effectively as states, reversing traditional power calculations and making deterrence especially difficult. Individuals can use the Net both for mischief and to escape from authoritarian controls; groups such as terrorists and criminals can target states, commerce and individuals; and states can attack other states both directly and by proxy. The complexity of possible online conflicts was seen clearly in the events triggered by Wikileaks disclosures against the USA in 2010 and 2011. Among other recent developments, an attack on the Pentagon and the ‘Stuxnet’ virus used against Iranian nuclear plants have shown how even the smallest devices can penetrate high-security systems, and that computer-driven infrastructures are no longer immune. Iceland, for its part, acknowledged the relevance of cyber-threats in its 2009 risk assessment, and recently decided to set up a coordinating team for protection; but it has lagged behind its Nordic neighbours in this field and should take full advantage of cooperation with them now. Vulnerable states also have an interest in international regulation and restraint on the use of cyber-weapons, but the context for this is complex and viable proposals are slow to emerge. Iceland can and should contribute to new thinking, and perhaps also assist poorer states: but it needs to put its own house in order first.

Levelized Cost of Energy Analysis of a Wind Power Generation System at Búrfell in Iceland

Directory of Open Access Journals (Sweden)

Birgir Freyr Ragnarsson

2015-09-01

Full Text Available Wind energy harnessing is a new energy production alternative in Iceland. Current installed wind power in Iceland sums to 1.8 MW, which in contrast is 0.1% of the country’s total electricity production. This article is dedicated to the exploration of the potential cost of wind energy production at Búrfell in the south of Iceland. A levelized cost of energy (LCOE approach was applied to the estimation of the potential cost. Weibull simulation is used to simulate wind data for calculations. A confirmation of the power law is done by comparing real data to calculated values. A modified Weibull simulation is verified by comparing results with actual on-site test wind turbines. A wind farm of 99MWis suggested for the site. Key results were the capacity factor (CF at Búrfell being 38.15% on average and that the LCOE for wind energy was estimated as 0.087–0.088 USD/kWh (assuming 10% weighted average cost of capital (WACC, which classifies Búrfell among the lowest LCOE sites for wind energy in Europe.

Managing Proliferation Issues with Iran

International Nuclear Information System (INIS)

Nelson, C. Richard; Saltiel, David H.

2002-01-01

Any government in Tehran will be inclined to seek weapons of mass destruction (WMD) and missile delivery options given the realities of its strategic environment. These weapons might help Iran to deter potential external threats, to achieve equality with other major regional powers armed with WMD, and to attain self-reliance in national security, given the isolating experience of arms embargoes. A more pluralist leadership in the future, however, may examine broader choices and trade-offs, and perhaps be less likely to cross key thresholds in WMD acquisition. In any event, Iran's WMD behavior is likely to be determined by both external factors, mainly the availability of crucial components, and internal factors, including calculations of costs, risks, and benefits. Among the benefits, psychological factors, such as prestige, will play an important role. Other important factors that might well shape Iran's WMD behavior include developments in Iraq, relations with the United States and other Gulf states, Israeli-Palestinian relations and the future price of oil. This paper offers recommendations on how the United States can best hope to influence Iranian decisions regarding the acquisition of WMD and missile delivery systems if the United States decides to pursue more direct engagement with Tehran. An engagement-nonproliferation strategy should involve at least three types of parallel efforts: public, private and indirect. Public efforts should seek to create a more positive, less-threatening image of the United States among opinion leaders in Iran. Private efforts should seek to determine the purposes, nature and extent of Iran's efforts to develop WMD and missiles and to suggest better alternatives for Iran's security and prestige needs. Indirect efforts should involve key third countries and organizations in an attempt both to address Iran's security concerns and to deny Iran access to critical WMD and missile technology and components.

We present IceMorph, a semi-supervised morphosyntactic analyzer of Old Icelandic. In addition to machine-read corpora and dictionaries, it applies a small set of declension prototypes to map corpus words to dictionary entries. A web-based GUI allows expert users to modify and augment data through an online process. A machine learning module incorporates prototype data, edit-distance metrics, and expert feedback to continuously update part-of-speech and morphosyntactic classification. An advantage of the analyzer is its ability to achieve competitive classification accuracy with minimum training data.

The importance of on-site evaluation for placing renewable energy in the landscape: A case study of the Búrfell wind farm (Iceland

Directory of Open Access Journals (Sweden)

Frantál Bohumil

2017-12-01

Full Text Available Using a case study of the Búrfell wind farm project, a large wind farm proposed in the Central Highlands of Iceland, the authors attempt to provide new insights into the factors shaping subjective landscape perceptions and attitudes to renewable energy developments, and into alternative methods that may be used for their assessment. The research was based on an on-site visit and actual experience of the place, investigated using a combination of mental mapping, the technique of the semantic differential and a questionnaire survey. The results show that participants visiting a landscape and using all sensory organs in combination with mental mapping, can reveal more important information than using only ‘laboratory’ methods with static photographs. The results suggest that the perception of landscape is highly subjective. Those perceiving the landscape as more open, homogenous, industrial, unfamiliar and resilient also consider it more compatible with wind turbines. The perception of the landscape’s compatibility with wind turbines proved to be a dominant factor shaping attitudes towards the project. The acceptance of wind turbines is not, however, inconsistent with the perception of landscape as beautiful, wild and unique. Participants from more densely populated countries and countries with a developed wind energy industry were more tolerant of wind turbines in the Icelandic landscape.

Iran`s petroleum policy: Current trends and the future outlook

Energy Technology Data Exchange (ETDEWEB)

Pezeshki, S.; Fesharaki, F.

1994-12-01

The Iranian economy and political situation have undergone radical changes since the 1979 Islamic revolution. The excesses of the early years of the revolution have gradually given way to moderation and a more pragmatic economic policy--based on the principles of the free market. The petroleum policy, as a subset of the economic policies, has been somewhat affected by the political and economic developments in Iran. The petroleum policy has changed from a position of no foreign participation to a position that includes a desire for foreign participation, the text of a model contract, and an attempt to introduce new technologies in the upstream sector. This report provides an overview of the key issues facing the Iranian oil industry and the economic context in which the oil industry is operating in Iran. It describes the evolution of policies meant to move the oil industry toward the free market; it discusses Iran`s oil trading partners, the outlook for refining and project investments, and current and likely future developments in the natural gas and petrochemical sectors. In short, the report provides an up-to-date assessment of the Iranian petroleum sector and its likely evolution in the future.

1992-01-01

This paper reports that during the past several years Iran's potentials have been forgotten or ignored by the outside world mainly due to misconceptions, fears, and political concerns attributed to the religious overtone. The intention of the authors is to introduction to the new realities of regional, as well as global geopolitics and the main political and economic aspects of Iran's huge and growing petroleum industry. The fact of the matter is that in the rapidly changing world order the need for a true stability in the region and a global cooperation has been recognized by Iran. The country, with a population of 60 million, is now preparing itself for the major political and economic role thrust upon the nation by the socio-economic changes in the integrating Europe; the outcome of the Iran-Iraq and the Persian Gulf wars, including the likely instability of the autocratic governments of Arab states of the region; the breakup of the former Soviet Union; and market changes in the Far East

To examine and explain the effect of unemployment on the number of disability pensioners in Iceland by examining changes in this relationship from 1992 to 2006. Information on gender and place of residence of new recipients of disability pension in Iceland and corresponding information on unemployment for each year in the period 1992 to 2006. The variables were correlated and disaggregated by gender and regions within Iceland. Two big fluctuations occurred in the rate of new disability pension receivers during the study period, with significant increases in disability from 1993 to 1995 and again from 2003 onwards. Both of these fluctuations are associated with considerable increases in the unemployment rate. The extent of new disability pensioners declined again when the level of unemployment went down, even though not to the same relative extent. In the upswing from 2003 a delay of about a year in the increase of disability pensioners' numbers, following the rise in unemployment rate, became more prominent and the overall rate of new disability pensioners reached new highs. The relationship applies equally to the capital area as well as the provincial areas as a whole. There is though a small deviation in three of the seven provincial areas, with less decline of the disability rate on the downswing. Health and capability condition determine the overall disability rate, but fluctuations over time are related to environmental conditions in the labour market, especially the unemployment rate. The features of the welfare system, especially the benefit and rehabilitation system, as well as the extent and character of activation measures in the labour market also influence the number of disability pensioners. A new method of disability assessment from late 1999 may have had some influence on the relationship during the latter part of the period and increasing applications from people with mental and psychiatric deficiencies seems to have had a significant influence on

Geodetic measurements and models of rifting in Northern Iceland for 1993-1998 (Invited)

Rifting occurs as episodes of active deformation in individual rift segments of the Northern Volcanic Zone (NVZ) in Iceland. Here we simulate deformation around the Krafla central volcano and rift system in NVZ in order to explain InSAR data acquired between 1993 and 1998. The General Inversion for Phase Technique (GIPhT) is used to model the InSAR phase data directly, without unwrapping [Feigl and Thurber, Geophys. J. Int., 2009]. Using a parallel simulated annealing algorithm, GIPhT minimizes the non-linear cost function that quantifies the misfit between observed and modeled values of the phase. We test the hypothesis that the observed deformation can be explained by a combination of at least three processes including: (i) secular plate spreading, (ii) post rifting relaxation following the Krafla rifting episode (1975-1984), and (iii) deflation of a shallow magma chamber beneath the central volcano. The calibration parameters include material properties of upper/lower crust and mantle as well as flux rates for the elements of the plumbing system. The best fitting Maxwell model favors a stronger lower crust (~1.0E+20 Pa.s) and a mantle viscosity of ~1.0E+18 Pa.s as well as a shallow deflating magma chamber. The deformation appears to be linear in time over the observed interval.

Drivers of Ecological Restoration: Lessons from a Century of Restoration in Iceland

Directory of Open Access Journals (Sweden)

Ása L. Aradóttir

2013-12-01

Full Text Available We analyzed the main drivers for ecological restoration in Iceland from 1907 to 2010 and assessed whether the drivers have changed over time and what factors might explain the changes, if any. Our study was based on a catalogue of 100 restoration projects, programs, and areas, representing 75% to 85% of all restoration activities in Iceland. Catastrophic erosion was an early driver for soil conservation and restoration efforts that still ranked high in the 2000s, reflecting the immense scale of soil erosion and desertification in Iceland. Socioeconomic drivers such as farming and the provision of wood products were strong motivators of ecological restoration over most of the 20th century, although their relative importance decreased with time as the number and diversity of drivers increased. In the 1960s and 1970s, the construction of hard infrastructure, and moral values such as improving the aesthetics of the countryside and "repaying the debt to the land" emerged as motivations for restoration actions. In the late 1990s, the United Nations Climate Change Convention became a driver for restoration, and the importance of nature conservation and recreation increased. Technological development and financial incentives did not show up as drivers of ecological restoration in our study, although there are some indications of their influence. Furthermore, policy was a minor driver, which might reflect weak policy instruments for ecological restoration and some counteractive policies.

This report describes the characterization of a new genotype of foot-and-mouth disease virus (FMDV) type A responsible for recent FMD outbreaks in the Middle East. Initially identified in samples collected in 2003 from Iran, during 2005 and 2006 this FMDV lineage (proposed to be named A-Iran-05) spread into Saudi Arabia and Jordan and then further west into Turkey reaching European Thrace in January 2007. Most recently A-Iran-05 has been found in Bahrain. To the east of Iran, it has been recognized in Afghanistan (2004-07) and Pakistan (2006-07). Throughout the region, this lineage is now the predominant genotype of FMDV serotype A sampled, and has appeared to have replaced the A-Iran-96 and A-Iran-99 strains which were previously encountered. In August 2007, a new A-Iran-05 sub-lineage (which we have called A-Iran-05(ARD-07)) was identified in Ardahan, Turkey, close to the border with Georgia. This new sub-lineage appeared to predominate in Turkey in 2008, but has, so far, not been identified in any other country. Vaccine matching tests revealed that the A-Iran-05 viruses are antigenically different to A-Iran-96 and more like A(22). These findings emphasize the importance of undertaking continued surveillance in the Middle East and Central Asia in order to detect and monitor the emergence and spread of new FMDV strains.

Insights into Earth's Accretion and Mantle Structure from Neon and Xenon in Icelandic Basalt (Invited)

Science.gov (United States)

Mukhopadhyay, S.

2010-12-01

The noble gases provide important constraints for planet accretion models and understanding mantle structure and dynamics. Recent work based on continental well gases indicate that the MORB source 20Ne/22Ne ratio is similar to the Ne-B component in chondrites [1,2]. However, ratios higher than Ne-B have been reported in plume-derived Devonian rocks form the Kola Peninsula [3]. Here I report high-precision noble gas data in an Icelandic basaltic glass that demonstrate plumes have a different 20Ne/22Ne ratio than the MORB source. The highest measured 20Ne/22Ne ratio from Iceland is ~12.9, very similar to values in the Kola plume, but quite distinct from the convecting upper mantle as constrained from the well gases [1,2]. Hence, the Icelandic and Kola plume data indicate that OIBs and MORBs have different 20Ne/22Ne ratios. Since 20Ne/22Ne ratios in the mantle cannot change, Earth must have accreted volatiles from at least two separate reservoirs. The differences in 20Ne/22Ne ratios between OIBs and MORBs further indicate that early heterogeneities in the Earth’s mantle have not been wiped away by 4.5 Gyrs of mantle convection, placing strong constraints on mixing and mass flow in the mantle. The requirement of limited direct mixing between plumes and MORB source is supported by 129Xe, formed through radioactive decay of now extinct 129I. Combined He, Ne, and Xe measurements demonstrate that the Iceland plume has a lower 129Xe/130Xe ratio than MORBs because it evolved with a I/Xe ratio distinct from the MORB source and not because of recycled atmosphere (which has low 129/130Xe) in the plume source. Since 129I became extinct 80 Myrs after solar system formation, limited mixing between plume and MORB source is a stringent requirement. Additionally, the high-precision Xe measurements reveal for the first time that the Iceland plume source has significantly higher proportion of plutonium derived fission xenon than MORBs, requiring the plume source to be less degassed

Understanding magmatic plumbing within the Earth's crust is important for understanding volcanic systems and improving eruption forecasting. We discuss magma plumbing under Bárðarbunga volcano, Iceland, over a 4 year period encompassing the largest Icelandic eruption in 230 years. Microseismicity extends through the usually ductile region of the Earth's crust, from 7 to 22 km depth in a subvertical column. Moment tensor solutions for an example earthquake exhibits opening tensile crack behavior. This is consistent with the deep (>7 km) seismicity being caused by the movement of melt in the normally aseismic crust. The seismically inferred melt path from the mantle source is offset laterally from the center of the Bárðarbunga caldera by 12 km, rather than lying directly beneath it. It is likely that an aseismic melt feed also exists directly beneath the caldera and is aseismic due to elevated temperatures and pervasive partial melt under the caldera.

The genetics of an early Neolithic pastoralist from the Zagros, Iran

2016-08-09

The agricultural transition profoundly changed human societies. We sequenced and analysed the first genome (1.39x) of an early Neolithic woman from Ganj Dareh, in the Zagros Mountains of Iran, a site with early evidence for an economy based on goat herding, ca. 10,000 BP. We show that Western Iran was inhabited by a population genetically most similar to hunter-gatherers from the Caucasus, but distinct from the Neolithic Anatolian people who later brought food production into Europe. The inhabitants of Ganj Dareh made little direct genetic contribution to modern European populations, suggesting those of the Central Zagros were somewhat isolated from other populations of the Fertile Crescent. Runs of homozygosity are of a similar length to those from Neolithic farmers, and shorter than those of Caucasus and Western Hunter-Gatherers, suggesting that the inhabitants of Ganj Dareh did not undergo the large population bottleneck suffered by their northern neighbours. While some degree of cultural diffusion between Anatolia, Western Iran and other neighbouring regions is possible, the genetic dissimilarity between early Anatolian farmers and the inhabitants of Ganj Dareh supports a model in which Neolithic societies in these areas were distinct.

Full Text Available Ethnopharmacological and ethnobotanical information have been known as effective tools for drug discovery. Iran is a location with long medical history. Darab is one of the cities in Iran which can be important in regard of ethnopharmacological aspects. Current paper documented the folk medical information by Darab inhabitants. Therefore, field studies on this area were conducted from March to July 2012 and May to July 2013 under supervision of one local person. A questionnaire was utilized in this study and was filled by local inhabitants. In total, 58 species belonging to 27 plant families were documented in management of 53 ailments. The most cited plant family was Asteraceae which was followed by Apiaceae, Lamiaceae and Papilionaceae. Herbs were applied for gynecologic and genitourinary, respiratory, central nervous system, infectious and cardiovascular ailments as well as musculoskeletal and skin disorders, respectively. This study can indicate the folk knowledge of a region in south of Iran. Moreover, the effectiveness of unexamined plants can be evaluated according to informants’ claims. Therefore, such investigations may be indeed, a useful way to search for drug discovery as well as keeping ethnopharmacological information alive.

This paper is a comprehensive assessment of the quality of soil in the Nakhlak mining district in Central Iran with special reference to potentially toxic metals. In this regard, an integrated approach involving geostatistical, correlation matrix, pollution indices, and chemical fractionation measurement is used to evaluate selected potentially toxic metals in soil samples. The fractionation of metals indicated a relatively high variability. Some metals (Mo, Ag, and Pb) showed important enrichment in the bioavailable fractions (i.e., exchangeable and carbonate), whereas the residual fraction mostly comprised Sb and Cr. The Cd, Zn, Co, Ni, Mo, Cu, and As were retained in Fe-Mn oxide and oxidizable fractions, suggesting that they may be released to the environment by changes in physicochemical conditions. The spatial variability patterns of 11 soil heavy metals (Ag, As, Cd, Co, Cr, Cu, Mo, Ni, Pb, Sb, and Zn) were identified and mapped. The results demonstrated that Ag, As, Cd, Mo, Cu, Pb, Sb, and Zn pollution are associated with mineralized veins and mining operations in this area. Further environmental monitoring and remedial actions are required for management of soil heavy metals in the study area. The present study not only enhanced our knowledge regarding soil pollution in the study area but also introduced a better technique to analyze pollution indices by multivariate geostatistical methods.

Full Text Available Background: Endometriosis is one of the most common gynecologic disorders. It is a complex trait and both genetic and environmental factors have been implicated in its pathogenesis. There is growing evidence indicating that exposure to environmental contaminants is a risk factor for endometriosis. Glutathione-S-Transferase M1 (GSTM1 is one of the genes involved in detoxification of endogenous and exogenous compounds. Objective: Several studies have indicated an association between GSTM1 null mutation and endometriosis. In this study, the possible association between the GSTM1 gene null genotype and susceptibility to endometriosis in woman from central and southern Iran was investigated.Materials and Methods: One hundred and one unrelated premenopausal women with endometriosis and 142 unrelated healthy premenopausal women without endometriosis were enrolled in the study. Genomic DNA was extracted from Peripheral blood in all subjects. GSTM1 null genotyping was performed by polymerase chain reaction (PCR.Results: There was no significant difference between frequencies of GSTM1 null genotype in case and control groups (50.5% Vs. 52.1%, p=0.804. Furthermore, this genotype was not associated with severity of endometriosis in our sample (p=0.77. Conclusion: further studies involving gene-environment and gene-gene interactions, particularly combination of GSTM1 and other GST gene family polymorphisms are needed.

Exposure to advertisements cannot fully explain the associations between young children's dietary intake and the time they spend in front of the television. It is therefore of importance to study television content other than advertisements in this aspect. The present study aimed to examine the nature and extent of verbal and visual appearances of foods and beverages in children's television programmes on Icelandic public service television. A total of 27 h of children's programmes (domestic and internationally produced) were watched. All verbal and visual appearances of foods and beverages were coded, as well as the context in which the foods/beverages were discussed or appeared. Children's programmes on Icelandic public service television. Two food groups were of special interest for their importance from a public health perspective: high-calorie and low-nutrient (HCLN) foods and fruits and vegetables (F&V). The χ 2 test and logistic regression were performed to analyse if the occurrence of the two groups was associated with the context where foods/beverages appeared. Of the 125 different programmes, a food or beverage appeared in 86 %. Of the total food appearances (n 599), HCLN foods accounted for 26 % and F&V for 23 %. HCLN foods were presented as desirable by appearing more frequently with child characters (Pfood and eating is presented in children's programmes, as young childhood is a critical period for founding healthy habits for later life.

Will you still need me, will you still feed me? Old-age pensions in Iceland from a gender perspective

Directory of Open Access Journals (Sweden)

Steinunn Rögnvaldsdóttir

2012-12-01

Full Text Available Icelandic women have through the years earned less occupational and supplemental pensions and depended more than men do on the basic pension of social security. Although women’s labour market participation has increased, the gender pay gap, unpaid labour in homes, and women’s fewer working hours in paid labour results in the extension of the labour market gender discrimination into old age. The structure of Icelandic pension funds is fundamentally male biased because of its tight connection to employment, despite the absence of direct discrimination factors. The article provides an overview of implications for a more women friendly pension system; based on multi-national research; the analysis of the Icelandic pension system, and statistical information on older women and men’s economic situation in Iceland. Adequate basic pension, elimination of labour market gender discrimination, and males taking greater responsibility for care- and housework, are some of the key issues in creating a more gender equal pension system. Sharing of pensions between spouses, the responsibility of pension-funds and companies, and possibilities of care credit systems to promote gender equality are also discussed.

2017-08-01

To examine the level of genetic differentiation in the sequences of the mitochondrial D-loop gene of Rhinolophus ferrumequinum, and to evaluate the current taxonomic status of this species, 50 tissue samples of greater horseshoe bats were collected in 2011-2015 from 21 different localities in northwest, northeast, west, central, and south regions of Iran. Twenty-two published D-loop sequences from Europe (Switzerland, United Kingdom, Bulgaria, and Tunisia), and Anatolia (south, west, and east Turkey) were downloaded from GenBank. Molecular genetic analyses revealed remarkable variation among populations of R. ferrumequinum. Two major clades with strong support were identified within the greater horseshoe bat. One of these clades consists of individuals of R. ferrumequinum from Iran and eastern Turkey, and is further subdivided into two subclades. A second clade includes samples from western Turkey and Europe. The two subclades from Iran and Turkey and the second clade from western Turkey and Europe represent three diagnosable categories, which most probably warrant three subspecies for the species. Thus, based on genetic differences, it is clear that two subspecific populations are found in Iran: R. f. irani (southern Iran) and R. f. proximus (northern Iran).

Medical isotope applications in Iceland

Energy Technology Data Exchange (ETDEWEB)

NONE

1962-10-15

About $ 12 000 worth of equipment and the services of an expert in the medical applications of radioisotopes were provided by IAEA to the Government of Iceland. The expert was primarily concerned with the establishment of a medical radioisotope laboratory at the State Hospital, Reykjavik. His specific tasks included the setting up of the equipment furnished by IAEA for radioactive measurements in medical work, the establishment of techniques for the routine uses of radioisotopes in medicine, and the training of personnel. The apparatus installed includes a well-type scintillation counter for small samples, a directional scintillation counter, and Geiger counters of different types. The laboratory is thus well equipped for nearly all the conventional applications of radioisotopes in medicine, except those involving very soft beta-ray emitting isotopes

Distribution, abundance and feeding ecology of baleen whales in Icelandic waters: have recent environmental changes had an effect?

Full Text Available The location of Iceland at the junction of submarine ridges in the North-East Atlantic where warm and cold water masses meet south of the Arctic Circle contributes to high productivity of the waters around the island. During the last two decades, substantial increases in sea temperature and salinity have been reported. Concurrently, pronounced changes have occurred in the distribution of several fish species and euphausiids. The distribution and abundance of cetaceans in the Central and Eastern North Atlantic have been monitored regularly since 1987. Significant changes in the distribution and abundance of several cetacean species have occurred in this time period. The abundance of Central North Atlantic humpback and fin whales has increased from 1,800 to 11,600 and 15,200 to 20,600, respectively, in the period 1987-2007. In contrast, the abundance of minke whales on the Icelandic continental shelf decreased from around 44,000 in 2001 to 20,000 in 2007 and 10,000 in 2009. The increase in fin whale abundance was accompanied by expansion of distribution into the deep waters of the Irminger Sea. The distribution of the endangered blue whale has shifted northwards in this period. The habitat selection of fin whales was analyzed with respect to physical variables (temperature, depth, salinity using a generalized additive model, and the results suggest that abundance was influenced by an interaction between the physical variables depth and distance to the 2000m isobaths, but also by sea surface temperature and sea surface height, However, environmental data generally act as proxies of other variables, to which the whales respond directly. Overall, these changes in cetacean distribution and abundance may be a functional feeding response of the cetacean species to physical and biological changes in the marine environment, including decreased abundance of euphausiids, a northward shift in summer distribution of capelin and a crash in the abundance of

Full Text Available Background and objectives: Hippophae rhamnoides L. known as sea buckthorn is a deciduous medicinal shrub belonging to Elaeagnaceae family. In this study, the most important chemical constituents of sea buckthornwere evaluated in wild populations of central Alborz Mountains in Iran during the growth season of 2014 and 2015. Methods: Phytochemical analysis of fruit pulp and seed oil traits was performed using different methods of chromatography such as spectrophotometry, HPLC and GC. Results: Based on the results of combined analysis of variance, significant (p≤0.01 difference ranges between populations were found in respect to fruit dry weight (21.32 to 32.03%, total phenolic compounds (20.78 to 34.60 mg/g, extractable tannin (1.99 to 5.74 mg/g, glucose (38.14 to 110.70 mg/g, total carotenoids (0.80 to 1.17 mg/g, lycopene (0.13 to 0.20 mg/g, β-carotene (0.18 to 0.26 mg/g, total flavonoids (0.98 to 2.80 mg/g, total soluble solids (TSS (11.85 to 31.50%, vitamin C (1.47 to 8.96 mg/g, seed oil content (4.51 to 7.91%, and two major unsaturated fatty acids including linoleic acid (28.71 to 37.44% and linolenic acid (21.52 to 28.28%. Factor analysis based on principal component analysis (PCA revealed most important traits with the highest correlation factor such as vitamin C, carbohydrates, TSS, fruit dry weight (FDW, and tannin for the first component. Conclusion: content of vitamin C was the main variable in chemical constituents for effective detection of original wild populations of central Alborz Mountains. Accordingly, sea buckthorn populations were divided into four main clusters and groups with high diversity based on their chemical compositions.

Full Text Available The idea of development gained hegemonic status in the middle of the 20th century as a way of understanding the relationship between different parts of the world. Even though debated how development would best be achieved, the idea as such was generally not critically assessed. Development institutions were seen as objective institutions with the technological knowledge necessary to move one society to the next level of development.The collection of data of these institutions in the so-called underdeveloped parts of the world involved the most intimate aspects of societies,and gave the idea of development content and meaning. The article looks at the origin of Icelandic development aid and aims at contextualizing it within international ideas of aid. The discussion starts with overview of historical appearance of international development globally and its hegemonic position. It focuses then on how the idea of development takes shape in an Icelandic context at a particular period and how it was shaped by international discourses, as is for example reflected in increased pressure on the Icelandic government to initiate an aid institution. The establishment of Iceland’s first governmental institutions focusing on aid in 1971 reflects still little interest by the Icelandic government at that time in international development. The article also shows how these international discourses become entangled with Icelandic nationalism, and thus the emphasis that the Icelandic nation-state would be engaged in international development.Hugmyndin um þróunarhjálp til handa fátækari hlutum heimsins fékk hugmyndafræðilegt forræði um miðja 20. öld og þá sem leið til að skilja stöðu ólíkra hluta heimsins.

Adib, Ahmad; Afzal, Peyman; Mirzaei Ilani, Shapour; Aliyari, Farhang

2017-10-01

The aim of this study is to determine a relationship between zinc mineralization and a major fault in the Behabad area, central Iran, using the Concentration-Distance to Major Fault (C-DMF), Area of Mineralized Zone-Distance to Major Fault (AMZ-DMF), and Concentration-Area (C-A) fractal models for Zn deposit/mine classification according to their distance from the Behabad fault. Application of the C-DMF and the AMZ-DMF models for Zn mineralization classification in the Behabad fault zone reveals that the main Zn deposits have a good correlation with the major fault in the area. The distance from the known zinc deposits/mines with Zn values higher than 29% and the area of the mineralized zone of more than 900 m2 to the major fault is lower than 1 km, which shows a positive correlation between Zn mineralization and the structural zone. As a result, the AMZ-DMF and C-DMF fractal models can be utilized for the delineation and the recognition of different mineralized zones in different types of magmatic and hydrothermal deposits.

Population-attributable fraction of hypertension associated with obesity, abdominal obesity, and the joint effect of both in the Central Provinces of Iran

Full Text Available The prevalence of obesity has been increasing in Iran over the past decade. This study aimed to determine the population-attributable fraction (PAF of hypertension associated with obesity, abdominal obesity, and the joint effect of both in the central provinces of Iran. Prevalence of hypertension was extracted from the Iranian Ministry of Health Non-Communicable Disease Risk Factor InfoBase 2009. Measure of association between obesity and hypertension was extracted from Tehran Lipid and Glucose Study, for males and females, in order to calculate the PAF of hypertension associated with obesity. Age standardization of the reported prevalence of obesity was done using the World Health Organization method. The PAF of hypertension associated with the joint effect of obesity and abdominal obesity in females was highest in Semnan Province: 22.7 [95% confidence interval (CI: 4.2–35.6], followed by Qom 21.09 (95% CI: 3.7–33.1, and Yazd 20.3 (95% CI: 3.5–32.1. In males, the highest PAF was observed in Qom Province 31.07 (95% CI: 16.7–41.1, followed by Semnan 29.6 (95% CI: 15.9–39.3, Qazvin 25.9 (95% CI: 13.7–34.5, Tehran 24.2 (95% CI: 12.7–32.3, and Isfahan 20.4 (95% CI: 3.5–27.4. Prevalence of hypertension is higher in more developed provinces. PAFs suggest that a sizable share of hypertension in these provinces is associated with obesity. It is recommended that health promotion programs focus on obesity in the provinces with a higher share of hypertension due to obesity.

Estimates of the abundance of minke whales (Balaenoptera acutorostrata from Faroese and Icelandic NASS shipboard surveys

Daniel G Pike

2009-09-01

Full Text Available North Atlantic Sightings Surveys for cetaceans were carried out Northeast and Central Atlantic in 1987, 1989, 1995 and 2001. Here we provide estimates of density and abundance for minke whales from the Faroese and Icelandic ship surveys. The estimates are not corrected for availability or perception biases. Double platform data collected in 2001 indicates that perception bias is likely considerable for this species. However comparison of corrected estimates of densityfrom aerial surveys with a ship survey estimate from the same area suggests that ship surveys can be nearly unbiased under optimal survey conditions with high searching effort. There were some regional changes in density over the period but no overall changes in density and abundance. Given the recent catch history for minke whales in this area, we would not expect to see changes in abundance due to exploitation that would be detectable with these surveys.

Hemoglobin Q-Iran detected in family members from Northern Iran: a case report

Khorshidi Mohammad

2012-02-01

Full Text Available Abstract Introduction Hemoglobin Q-Iran (α75Asp→His is an important member of the hemoglobin Q family, molecularly characterized by the replacement of aspartic acid by histidine. The first report of hemoglobin Q-Iran and the nomenclature of this hemoglobinopathy dates back to 1970. Iran is known as a country with a high prevalence of α- and β-thalassemia and different types of hemoglobinopathy. Many of these variants are yet to be identified as the practice of molecular laboratory techniques is limited in this part of the world. Applying such molecular methods, we report the first hemoglobin Q-Iran cases in Northern Iran. Case presentation An unusual band was detected in an isoelectric focusing test and cellulose acetate electrophoresis of a sample from a 22-year-old Iranian man from Mazandaran Province. Capillary zone electrophoresis analysis identified this band as hemoglobin Q. A similar band was also detected in his mother's electrophoresis (38 years, Iranian ethnicity. The cases underwent molecular investigation and the presence of a hemoglobin Q-Iran mutation was confirmed by the amplification refractory mutation system polymerase chain reaction method. Direct conventional sequencing revealed a single guanine to cytosine missense mutation (c.226G > C; GAC >CAC at codon 75 in the α-globin gene in both cases. Conclusion The wide spectrum and high frequency of nondeletional α-globin mutations in Mazandaran Province is remarkable and seem to differ considerably from what has been found in Mediterranean populations. This short communication reports the first cases of patients with hemoglobin Q found in that region.

Heterogenity of Echinococcus canadensis genotype 6 - the main causative agent of cystic echinococcosis in Birjand, Eastern Iran.

Little is known about the genotypes of Echinococcus spp. and their life cycles in eastern Iran. We analysed the partial sequences of the nad1 and cox1 genes from 17 isolates from hydatid cyst-infected patients (n=9), camels (n=5) and sheep (n=3) in Birjand, eastern Iran. A new primer pair was also used to amplify the long fragment (1180bp) of the cox1 gene. All camel and eight human isolates were G6 strains of Echinococcus canadensis while one human isolate and the three sheep isolates were G1 genotypes (sheep strain) of E. granulosus sensu stricto (s.s.). Nad1 and cox1 sequence analyses showed high G6 genetic homogeneity, similar to previously reported G6 strains from southeast and central Iran, Sudan and Mauritania. Low nucleotide and haplotype diversity similar to G6 strains from Russia (Altai republic) and Kazakhstan was also found, consistent with a bottleneck effect. In this study, G6 was the most common Echinococcus genotype. Genetic homogeneity of east, southeast and central Iranian G6 and its low genetic diversity may be due limited mobility and contact between humans and camels from other regions because of large, inhospitable deserts.

Osteochondral lesions in the joints of the distal tarsal region of young Icelandic horses provide a natural model for the early stages of osteoarthritis (OA) in low-motion joints. We describe and characterise mineralised and non-mineralised osteochondral lesions in left distal tarsal region joint specimens from twenty-two 30 ±1 month-old Icelandic horses. Combinations of confocal scanning light microscopy, backscattered electron scanning electron microscopy (including, importantly, iodine staining) and three-dimensional microcomputed tomography were used on specimens obtained with guidance from clinical imaging. Lesion-types were described and classified into groups according to morphological features. Their locations in the hyaline articular cartilage (HAC), articular calcified cartilage (ACC), subchondral bone (SCB) and the joint margin tissues were identified and their frequency in the joints recorded. Associations and correlations between lesion-types were investigated for centrodistal joints only. In centrodistal joints the lesion-types HAC chondrocyte loss, HAC fibrillation, HAC central chondrocyte clusters, ACC arrest and ACC advance had significant associations and strong correlations. These lesion-types had moderate to high frequency in centrodistal joints but low frequencies in tarsometatarsal and talocalcaneal-centroquartal joints. Joint margin lesion-types had no significant associations with other lesion-types in the centrodistal joints but high frequency in both the centrodistal and tarsometatarsal joints. The frequency of SCB lesion-types in all joints was low. Hypermineralised infill phase lesion-types were detected. Our results emphasise close associations between HAC and ACC lesions in equine centrodistal joints and the importance of ACC lesions in the development of OA in low-motion compression-loaded equine joints.

2012-01-01

The Icelandic financial collapse, which occurred in the fall of 2008, is without precedent. Never before in modern history has an entire financial system of a developed country collapsed so dramatically. This paper describes the country's path towards financial liberalisation and the economic...... background that lead to an initially flourishing banking sector. In doing so, the paper elaborates on the economic oversights that were made during the financial build-up of the country and how such mistakes contributed to the crash. The focus is thus on identifying the main factors that contributed...... to the financial collapse and on drawing conclusions about how these missteps could have been avoided. Also summarised are the mistakes that followed in the attempted rescue phase after the disaster had struck. The paper discusses these issues from a general perspective to provide an overview of the pitfalls...

2005-01-01

In order to map Cd and Pb contamination in the soils of the region of Isfahan, Central Iran, we performed indicator kriging on a set of 255 topsoil samples (0-20 cm) gathered irregularly from an area of 6800 km 2 . The measured Cd concentrations exceeded the Swiss guide value in more than 80% of the samples whereas Pb concentrations exceeded the respective guide value only in 2% of the samples. Based on the simulated conditional distribution functions, the probability of exceeding the concentration of Cd and Pb from the specific threshold was computed. The results indicated that in most parts of the region the probability of contamination by Cd is very large (>0.95) whereas it is small (<0.5) for Pb. Based on a misclassification analysis, we chose the probability of 0.45 as optimum probability threshold to delineate the polluted from unpolluted areas for Cd. In addition, we performed a loss analysis to separate risks to human health from potential losses due to remediation costs. Based on this analysis a probability threshold of 0.8 was found to be the optimum threshold for the classification of polluted and unpolluted areas in the case of Cd. Health risks were found to be larger in the western parts of the region. Misclassification analysis was sufficient for risk mapping for Pb as its concentration did not reach risk levels for human health. A probability of 0.7 for Pb was found to be the optimum threshold for the delineation of polluted and unpolluted lands

Managing Proliferation Issues with Iran; FINAL

International Nuclear Information System (INIS)

Nelson, C. Richard; Saltiel, David H.

2002-01-01

Any government in Tehran will be inclined to seek weapons of mass destruction (WMD) and missile delivery options given the realities of its strategic environment. These weapons might help Iran to deter potential external threats, to achieve equality with other major regional powers armed with WMD, and to attain self-reliance in national security, given the isolating experience of arms embargoes. A more pluralist leadership in the future, however, may examine broader choices and trade-offs, and perhaps be less likely to cross key thresholds in WMD acquisition. In any event, Iran's WMD behavior is likely to be determined by both external factors, mainly the availability of crucial components, and internal factors, including calculations of costs, risks, and benefits. Among the benefits, psychological factors, such as prestige, will play an important role. Other important factors that might well shape Iran's WMD behavior include developments in Iraq, relations with the United States and other Gulf states, Israeli-Palestinian relations and the future price of oil. This paper offers recommendations on how the United States can best hope to influence Iranian decisions regarding the acquisition of WMD and missile delivery systems if the United States decides to pursue more direct engagement with Tehran. An engagement-nonproliferation strategy should involve at least three types of parallel efforts: public, private and indirect. Public efforts should seek to create a more positive, less-threatening image of the United States among opinion leaders in Iran. Private efforts should seek to determine the purposes, nature and extent of Iran's efforts to develop WMD and missiles and to suggest better alternatives for Iran's security and prestige needs. Indirect efforts should involve key third countries and organizations in an attempt both to address Iran's security concerns and to deny Iran access to critical WMD and missile technology and components.

Full Text Available This study is focused on sedimentary environments, facies distribution, and sequence stratigraphy. The facies and sequence stratigraphic analyses of the Bahram Formation (middle–late Devonian in south-central Iran are based on two measured stratigraphic sections in the southern Tabas block. The Bahram Formation overlies red sandstones Padeha Formation in sections Hutk and Sardar and is overlain by Carboniferous carbonate deposits of Hutk Formation paraconformably, with a thickness of 354 and 386 m respectively. Mixed siliciclastic and carbonate sediments are present in this succession. The field observations and laboratory studies were used to identify 14 micro/petrofacies, which can be grouped into 5 depositional environments: shore, tidal flat, lagoon, shoal and shallow open marine. A mixed carbonate-detrital shallow shelf is suggested for the depositional environment of the Bahram Formation which deepens to the east (Sardar section and thins in southern locations (Hutk section. Three 3rd-order cyclic siliciclastic and carbonate sequences in the Bahram Formation and one sequence shared with the overlying joint with Hutk Formation are identified, on the basis of shallowing upward patterns in the micro/pertofacies.

Dissolution of subglacial volcanic glasses from Iceland: laboratory study and modelling

International Nuclear Information System (INIS)

Crovisier, J.-L.; Honnorez, J.; Fritz, B.; Petit, J.-C.

1992-01-01

Subglacial hyaloclastites from Iceland with ages ranging from 2 ka to 2.2 Ma have been studied from a mineralogical and geochemical standpoint. The chemical composition of palagonite (alteration crust formed on the surface of the glass) is almost identical with that of the clayey material filling the intergranular spaces of the rock. The clayey material is made up of two particle populations: the first is Si-, Mg-and Ca-rich with a smectite structure, while the second is amorphous, Fe-, Ti- and Al-rich, and has a smectite-like morphology. It is suggested that these two types of particles can be formed simultaneously, in the same solution, such that it is not necessary to explain their existence by local or temporary equilibria. The mineralogical sequences observed in natural samples were reproduced using the geochemical computer code DISSOL. The geochemical mass balances calculated with DISSOL also fit quite well with those calculated from Icelandic samples, illustrating the predictive capability of such a calculation code and give us confidence in applying a similar approach to nuclear waste-form glass problems.

2017-04-01

The Cenozoic climate transition from greenhouse to icehouse conditions was associated with major paleogeographic changes in the Tethyan realm. The closure of the Tethyan Seaway and its Iranian gateways during the terminal Paleogene and early Neogene, between approximately 28 and 18 million years, influenced the latitudinal exchange of water masses and energy and is documented in sediment successions of the Qom formation in central Iran. Little is known on the spatial expression and the exact depositional histories of the Qom Formation on orbital time-scales, including a lack of quantitative sea-level reconstructions and studies on the impact of climatic and tectonic changes on marine ecosystems and sedimentation processes. The PhD project focuses on the investigation of lithostratigraphy, biostratigraphy, paleoecology and paleoenvironmental evolution of the Iranian gateways based on late Oligocene to early Miocene foraminiferal faunas and carbonate facies from selected sediment sections of the Qom Basin. The Qom Formation was deposited in the Central Iranian back-arc basin during the Oligocene-Miocene. In this study foraminiferal faunas and carbonate microfacies were studied based on total 191 samples of two section of Qom Formation. One of them is Molkabad section, which is located northwest of Molkabad mountains, southeast of Garmsar. The section mainly consists of limestones, calcareous marls, marls, and gypsum-bearing marls with a total thickness of 760 meters. The Qom Formation at Molkabad section overlies Eocene rocks with an unconformity and consists of the following lithostratigraphic units (from the lower to upper part): Lithothamnium Limestone, Lower Marl Limestone, Bryozoa Limestone, and Upper Marl Group. The Molkabad fault separates the Qom Formation from the overlying Upper Red Formation. The other section is located at Navab anticline in Qom Formation .The section mainly consist of limestone, marl, and gypsum with a total thickness of 318 meters Navab

Full Text Available Diversification of production by including a broader range of plant species, can significantly contribute to improve health and nutrition, livelihoods, household food security and ecological sustainability. Exploring the climate impact on any given crop is one of the first priorities to find new suitable areas for production and management of new crops. Summer squash (Cucurbita pepo L. is an economically valuable plant with various medicinal potentials. In order to investigate summer squash cultivation feasibility under Iran�s climate, three main agricultural regions (Azerbaijan, Khorasan and central part of Iran (Fars and Isfahan were selected. These regions suitability for summer squash cultivation were evaluated by considering three vital climate variables encompass temperature, precipitation, and sunshine hours. These regions show distinct and representative climatic conditions of Iran. Annual and growing season average of maximum, minimum, mean temperature, precipitation, and sunshine hours were calculated (May-September for all locations with 44 years historical weather data (1961-2005 for 8 locations (Oroomieh, Tabriz, Khoy, Mashhad, Sabzevar, Birjand, Shiraz and Isfahan, 39 years (1966-2005 for 2 locations (Kashan and Fassa, 28 years (1977-2005 for 4 locations (Ardebil, Abadeh, Bojnurd and Shargh Isfahan and 20 years (1985-2005 for 9 locations (Mahabad, Sarab, Maragheh, Parsabad, Khalkhal, Ferdous, Ghaen, Kashmar and Sarakhs. Climatic demands of summer squash were determined by four years field studies at four different locations in Iran. Our results showed Azerbaijan region has a suitable condition for this crop cultivation especially from precipitation and temperature perspectives. Central part of Iran and Khorasan were also found as partly suitable locations however as they are near to deserts with hotter and drier climate, there might be some other crops considered as priorities in these areas.

Assessing the long-term probabilistic volcanic hazard for tephra fallout in Reykjavik, Iceland: a preliminary multi-source analysis

Science.gov (United States)

Tonini, Roberto; Barsotti, Sara; Sandri, Laura; Tumi Guðmundsson, Magnús

2015-04-01

Icelandic volcanism is largely dominated by basaltic magma. Nevertheless the presence of glaciers over many Icelandic volcanic systems results in frequent phreatomagmatic eruptions and associated tephra production, making explosive eruptions the most common type of volcanic activity. Jökulhlaups are commonly considered as major volcanic hazard in Iceland for their high frequency and potentially very devastating local impact. Tephra fallout is also frequent and can impact larger areas. It is driven by the wind direction that can change with both altitude and season, making impossible to predict a priori where the tephra will be deposited during the next eruptions. Most of the volcanic activity in Iceland occurs in the central eastern part, over 100 km to the east of the main population centre around the capital Reykjavík. Therefore, the hazard from tephra fallout in Reykjavík is expected to be smaller than for communities settled near the main volcanic systems. However, within the framework of quantitative hazard and risk analyses, less frequent and/or less intense phenomena should not be neglected, since their risk evaluation depends on the effects suffered by the selected target. This is particularly true if the target is highly vulnerable, as large urban areas or important infrastructures. In this work we present the preliminary analysis aiming to perform a Probabilistic Volcanic Hazard Assessment (PVHA) for tephra fallout focused on the target area which includes the municipality of Reykjavík and the Keflavík international airport. This approach reverts the more common perspective where the hazard analysis is focused on the source (the volcanic system) and it follows a multi-source approach: indeed, the idea is to quantify, homogeneously, the hazard due to the main hazardous volcanoes that could pose a tephra fallout threat for the municipality of Reykjavík and the Keflavík airport. PVHA for each volcanic system is calculated independently and the results

Investigations of Very High Enthalpy Geothermal Resources in Iceland.

2012-12-01

The Iceland Deep Drilling Project (IDDP) is investigating the economic feasibility of producing electricity from supercritical geothermal reservoirs. Earlier modeling indicates that the power output of a geothermal well producing from a supercritical reservoir could potentially be an order of magnitude greater than that from a conventional hot geothermal reservoir, at the same volumetric flow rate. However, even in areas with an unusually high geothermal gradient, for normal hydrostatic pressure gradients reaching supercritical temperatures and pressures will require drilling to depths >4 km. In 2009 the IDDP attempted to drill the first deep supercritical well, IDDP-01, in the caldera of the Krafla volcano, in NE Iceland. However drilling had to be terminated at only 2.1 km depth when ~900°C rhyolite magma flowed into the well. Our studies indicate that this magma formed by partial melting of hydrothermally altered basalts within the Krafla caldera. Although this well was too shallow to reach supercritical pressures, it is highly productive, and is estimated to be capable of generating up to 36 MWe from the high-pressure, superheated steam produced from the upper contact zone of the intrusion. With a well-head temperature of ~440°C, it is at present apparently the hottest producing geothermal well in the world. A pilot plant is investigating the optimal utilization of this magmatically heated resource. A special issue of the journal Geothermics with 16 papers reporting on the IDDP-01 is in preparation. However, in order to continue the search for supercritical geothermal resources, planning is underway to drill a 4.5 km deep well at Reykjanes in SW Iceland in 2013-14. Although drilling deeper towards the heat source of this already developed high-temperature geothermal field will be more expensive, if a supercritical resource is found, this cost increase should be offset by the considerable increase in the power output and lifetime of the Reykjanes geothermal

The Iceland Deep Drilling Project research well RN-15/IDDP-2 at Reykjanes, Iceland, reached its target of supercritical conditions at a depth of 4.5 km in January 2017. After only 6 days of heating, the measured bottom hole temperature was 426 °C, and the fluid pressure was 34 MPa. The southern tip of the Reykjanes peninsula is the landward extension of the Mid-Atlantic Ridge in Iceland. Reykjanes is unique among Icelandic geothermal systems in that it is recharged by seawater, which has a critical point of 406 °C at 29.8 MPa. The geologic setting and fluid characteristics at Reykjanes provide a geochemical analog that allows us to investigate the roots of a mid-ocean ridge submarine black smoker hydrothermal system. Drilling began with deepening an existing 2.5 km deep vertical production well (RN-15) to 3 km depth, followed by inclined drilling directed towards the main upflow zone of the system, for a total slant depth of 4659 m ( ˜ 4.5 km vertical depth). Total circulation losses of drilling fluid were encountered below 2.5 km, which could not be cured using lost circulation blocking materials or multiple cement jobs. Accordingly, drilling continued to the total depth without return of drill cuttings. Thirteen spot coring attempts were made below 3 km depth. Rocks in the cores are basalts and dolerites with alteration ranging from upper greenschist facies to amphibolite facies, suggesting that formation temperatures at depth exceed 450 °C. High-permeability circulation-fluid loss zones (feed points or feed zones) were detected at multiple depth levels below 3 km depth to bottom. The largest circulation losses (most permeable zones) occurred between the bottom of the casing and 3.4 km depth. Permeable zones encountered below 3.4 km accepted less than 5 % of the injected water. Currently, the project is attempting soft stimulation to increase deep permeability. While it is too early to speculate on the energy potential of this well and its economics, the IDDP

The aim of the current study was to characterize vector-borne protozoa in the blood of dromedaries from Iran by molecular tools.Methods: From June to July 2014, 200 peripheral blood samples were collected from asymptomatic one-humped camels in two provinces of Kerman and Sistan- va-Baloochestan in central and southeastern Iran. Microscopic examination was performed on Giemsa-stained blood smears, and drops of blood were spotted on Whatman FTA® cards for further analyses. Genomic DNA was extracted from the cards, and PCR was carried out for the detection of piroplasms and trypanosomes, followed by sequence analysis of positive samples.Results: One sample was positive Trypanosoma spp. trypomastigotes in light microscopy. PCR results revealed one positive sample each with Theileria annulata and Trypanosoma evansi.Conclusion: Camels were identified as hosts for bovine Mediterranean theileriosis in the investigated area. The presence of Tr. evansi, the causative agent of surra disease, was also confirmed in camels of Iran. Further studies are recommended in order to investigate their impact on the health and productivity of camels and other livestock in this region.

Nuclear cardiology is one of the most active branches of nuclear medicine and plays important role in diagnosis in treatment of CAD patients. Few nuclear cardiology surveys were published in the literature, mostly from developed countries. A nuclear cardiology survey in Iran and analysis of the findings in comparison with other countries may lead to better decision making and improve practice in our country. A questionnaire was sent by mail or e-mail to all nuclear medicine centers in Iran asking for details of nuclear cardiology practice. Also ownership of the centers, number of gamma cameras and number of cardiac studies in each week were recorded. Some centers were studied using telephone interview. From 79 nuclear medicine centers in Iran, 55 centers (69.6%) filled the questionnaire including 28 centers in Tehran and 27 centers in other cities. There was 69 Gamma cameras in these centers, 62.3% with SPECT capability. It is estimated that we may have 100 gamma cameras in Iran. This study showed that about 68287 cardiac studies were done in Iran each year with Myocardial perfusion scan accounting for about 99 2% of the studies. Considering population of the country nuclear cardiology activity will be about 1.05 study/1000/year. Regarding radiotracers used, about 13.5% of studies were done with T I-201, with some centers using only Tc- 99 m-M I B I

Status of Iran's nuclear program and negotiations

International Nuclear Information System (INIS)

Albright, David

2014-01-01

Iran's nuclear program poses immense challenges to international security. Its gas centrifuge program has grown dramatically in the last several years, bringing Iran close to a point where it could produce highly enriched uranium in secret or declared gas centrifuge plants before its breakout would be discovered and stopped. To reduce the risk posed by Iran's nuclear program, the P5+1 have negotiated with Iran short term limits on the most dangerous aspects of its nuclear programs and is negotiating long-term arrangements that can provide assurance that Iran will not build nuclear weapons. These long-term arrangements need to include a far more limited and transparent Iranian nuclear program. In advance of arriving at a long-term arrangement, the IAEA will need to resolve its concerns about the alleged past and possibly on-going military dimensions of Iran's nuclear program

Punctuated Holocene climate of Vestfirðir, Iceland, linked to internal/external variables and oceanographic conditions

Science.gov (United States)

Harning, David J.; Geirsdóttir, Áslaug; Miller, Gifford H.

2018-06-01

Emerging Holocene paleoclimate datasets point to a non-linear response of Icelandic climate against a background of steady orbital cooling. The Vestfirðir peninsula (NW Iceland) is an ideal target for continued climate reconstructions due to the presence of a small ice cap (Drangajökull) and numerous lakes, which provide two independent means to evaluate existing Icelandic climate records and to constrain the forcing mechanisms behind centennial-scale cold anomalies. Here, we present new evidence for Holocene expansions of Drangajökull based on 14C dates from entombed dead vegetation as well as two continuous Holocene lake sediment records. Lake sediments were analyzed for both bulk physical (MS) and biological (%TOC, δ13C, C/N, and BSi) parameters. Composite BSi and C/N records from the two lakes yield a sub-centennial qualitative perspective on algal (diatom) productivity and terrestrial landscape stability, respectively. The Vestfirðir lake proxies suggest initiation of the Holocene Thermal Maximum by ∼8.8 ka with subsequent and pronounced cooling not apparent until ∼3 ka. Synchronous periods of reduced algal productivity and accelerated landscape instability point to cold anomalies centered at ∼8.2, 6.6, 4.2, 3.3, 2.3, 1.8, 1, and 0.25 ka. Triggers for cold anomalies are linked to variable combinations of freshwater pulses, low total solar irradiance, explosive and effusive volcanism, and internal modes of climate variability, with cooling likely sustained by ocean/sea-ice feedbacks. The climate evolution reflected by our glacial and organic proxy records corresponds closely to marine records from the North Iceland Shelf.

Environment - Geothermal, the energy to wake up - Stimulation rather than fracturing - Iceland, the Texas of geothermal energy

2013-01-01

A first article comments the current efforts for the development of geothermal in France after a period during which it has been given up. It evokes the project of a geothermal plant near Paris (to supply Arcueil and Gentilly with energy), the increasing number of projects in different countries. It outlines the French delay in this sector, and that geothermal energy is as difficult to find as oil. It evokes the new actors of the sector and outlines the fierce competition in front of Icelander, Italian, US and Japanese actors, and the opportunities for the French ones. A second article comments the use of the hydraulic stimulation in geothermal energy exploration rather than hydraulic fracturing as in shale gas exploration, and outlines that according to geothermal energy actors this technique avoids the risk of micro-earthquake. A last article describes the activity of the geothermal sector in Iceland: geothermal energy supplies two thirds of primary energy consumption in this country. It exploits the Icelander volcanism. This development has been particularly noticeable since 2000, but some questions are raised regarding the production potential

This paper develops a system dynamics model of Iceland's energy sector (UniSyD I S) that is based on the UniSyD N Z model of New Zealand's energy economy. The model focuses on the energy supply sector with endogenous representation of road transport energy demand. Equilibrium interactions are performed across electricity, hydrogen, biofuels, and road transport sectors. Possible transition paths toward a low-carbon transport in Iceland are explored with implications for fuel demand, greenhouse gas (GHG) emissions and associated costs. The consumer sector simulates the long-term evolution of light and heavy-duty vehicles through a vehicle choice algorithm that accounts for social influences and consumer preferences. Through different scenarios, the influences of four fundamental driving factors are examined. The factors are oil price, carbon tax, fuel supply-push, and government incentives. The results show that changes in travel demand, vehicle technologies, fuel types, and efficiency improvements can support feasible transition paths to achieve sufficient reduction in GHG for both 4 °C and 2 °C climate scenarios of the Nordic Energy Technology Perspectives study. Initial investment in supply infrastructure for alternative fuels will not only mitigate GHG emissions, but also could provide long-term economic benefits through fuel cost saving for consumers and reduced fuel import costs for government. - Highlights: • UniSyD I S is an energy system model with endogenous road transport energy demand. • Possible transition paths to low-carbon road transport system in Iceland are explored. • Vehicle choice sector accounts for social influences and consumers’ preferences. • Supply-push costs can be offset by mitigation benefits and fuel cost savings

To study agents of animal wound myiasis in various geographical districts of Fars province. This study has been done in Fars province, located in the southern part of Iran. Sums of 10 358 domestic animals have been visited from April 2011 to March 2012. The infected wounds in any parts of animal body were sampled by means of forceps. About 61% of all animal wound myiasis were caused by larvae of Wohlfahrtia magnifica. The most wound myiasis cases due to this species occurred in central part of Fars province. There wasn't any significant difference between sheep and goat in infestation with myiasis (P>0.05). The infestation rate of myiasis in cattle community was 0.86%. The infestation rate of livestock was lower than other works in Iran and some other countries like Saudi Arabia. Chrysomya bezziana has been mentioned as main myiasis agent in Iran. But in this study it cleared that similarly to some European countries, the common animal myiasis agent in Iran is Wohlfahrtia magnifica. Introducing new species as principal agent for myiasis can help public health and animal husbandry policy makers to prepare sufficient and effective control and/or preventive measures for this disease.

Iran's petrochemical industry : status and prospects

2006-01-01

This presentation provided some basic information, current status and prospects for Iran's petrochemical industry with particular reference to Iran's National Petrochemical Company (NPC), one of the fastest growing chemical producers and exporters in the world. According to Chemical Marketing Associates Inc. (CMAI), NPC will become the second largest commodity chemical producer in the world by 2015, ranking only behind Dow Chemical. Product categories include chemicals and aromatics; fertilizers; polymers; feedstocks and gas. Opportunities for cooperation with North America were also identified. Iran's domestic markets were shown to be well developed downstream petrochemical industries producing a broad range of industrial and consumer goods. Iran's foreign markets include Asia (66 per cent), Middle East (25 per cent), and Europe (9 per cent). This presentation examined Iran's comparative advantage in the further development of its petrochemical/chemical industries. Some details of NPC's organizational structure were also provided, along with production, domestic sales, exports and ongoing expansion and development projects. Remarks on the projected and potential growth in NPC's position in the world markets were included with reference to potential for foreign participation and investment into the petrochemical industry in Iran. tabs., figs

Ideological Cooperation versus Cold War Realpolitik - The SED and the Icelandic Socialist Party

Directory of Open Access Journals (Sweden)

Valur Ingimundarson

2007-01-01

Full Text Available The article deals with the relationship between the East German Socialist Unity Party (SED and the Icelandic Socialist Party (SEI during the Cold War. It details the structural limitations of ideological cooperation between the two parties – Iceland’s NATO membership and the U.S. military presence – as well as its possibilities, especially in the 1950s, through the governmental participation of the SEI. Special attention is devoted to the role played by Einar Olgeirsson, the chairman of the SEI 1939–1968, who was instrumental in forging and developing political, economic, and cultural ties with the SED and the German Democratic Republic. The article argues that this experiment in transnational solidarity between socialist parties from two radically different political systems failed in the end due to several factors, including ideological differences and the political and economic development in Iceland.

An overview of the Icelandic Volcano Observatory response to the on-going rifting event at Bárðarbunga (Iceland) and the SO2 emergency associated with the gas-rich eruption in Holuhraun

On 16 August, 2014, Bárðarbunga volcano entered a new phase of unrest. Elevated seismicity in the area with up to thousands of earthquakes detected per day and significant deformation was observed around the Bárðarbunga caldera. A dike intrusion was monitored for almost two weeks until a small, short-lived effusive eruption began on 29 August in Holuhraun. Two days later a second, more intense, tremendously gas-rich eruption started that is still (as of writing) ongoing. The Icelandic Volcano Observatory (IVO), within the Icelandic Meteorological Office (IMO), monitors all the volcanoes in Iceland. Responsibilities include evaluating their related hazards, issuing warnings to the public and Civil Protection, and providing information regarding risks to aviation, including a weekly summary of volcanic activity provided to the Volcanic Ash Advisory Center in London. IVO has monitored the Bárðarbunga unrest phase since its beginning with the support of international colleagues and, in collaboration with the University of Iceland and the Environment Agency of Iceland, provides scientific support and interpretation of the ongoing phenomena to the local Civil Protection. The Aviation Color Code, for preventing hazards to aviation due to ash-cloud encounter, has been widely used and changed as soon as new observations and geophysical data from the monitoring network have suggested a potential evolution in the volcanic crisis. Since the onset of the eruption, IVO is monitoring the gas emission by using different and complementary instrumentations aimed at analyzing the plume composition as well as estimating the gaseous fluxes. SO2 rates have been measured with both real-time scanning DOASes and occasional mobile DOAS traveses, near the eruption site and in the far field. During the first month-and-a-half of the eruption, an average flux equal to 400 kg/s was registered, with peaks exceeding 1,000 kg/s. Along with these measurements the dispersal model CALPUFF has

This article describes environmental conditions in Iran including air pollution, pesticide pollution, soil depletion and erosion, water pollution, natural resource loss, lack of appropriate waste management, lead poisoning, and desertification. Environmental policy and implementation is described under the Shah and the Islamic Republic. Iran is beset with interrelated problems of environmental degradation, unemployment, poverty, and population growth. Sustainability is being undermined at the cost of future generations. In 1995, Iran had a population of 67 million and a growth rate of 3.6%. Population is expected to exceed 100 million by the year 2000. The country is having difficulty in maintaining its current infrastructure, housing, food, and educational facilities. Competition for admission in higher education discourages women. Women with lower levels of education results in continued supremacy of men over women, more polygamy, and a lower quality of life for women. Iran was food self-sufficient in 1970, and exported its surplus. Today, Iran may be permanently dependent on food imports. Iran has abundant oil reserves, natural gas, copper, lead, and marketable items. Exchanging natural resources for food and technology has time and resource limits. Iran needs monetary assistance from wealthy nations. Population growth leads to increased demand for infrastructure and resources. Iran has signed many international environmental agreements and has enacted detailed environmental policies and regulations, but actual enforcement is lacking.

2014-01-01

Possible explanations for the rapid increase in house prices and housing investment in Iceland between 2004 and 2007 and the subsequent market crash are studied. The boom was driven in part by banking liberalisation, international financial conditions, and domestic policies. A simple demand and supply model, based on the study by Elíasson and Pétursson (2009), is fitted to data through the recent boom-bust period. The model is remarkably robust through the cycle despite its unprecedented ampl...

Basaltic cannibalism at Thrihnukagigur volcano, Iceland

Science.gov (United States)

Hudak, M. R.; Feineman, M. D.; La Femina, P. C.; Geirsson, H.

2014-12-01

Magmatic assimilation of felsic continental crust is a well-documented, relatively common phenomenon. The extent to which basaltic crust is assimilated by magmas, on the other hand, is not well known. Basaltic cannibalism, or the wholesale incorporation of basaltic crustal material into a basaltic magma, is thought to be uncommon because basalt requires more energy than higher silica rocks to melt. Basaltic materials that are unconsolidated, poorly crystalline, or palagonitized may be more easily ingested than fully crystallized massive basalt, thus allowing basaltic cannibalism to occur. Thrihnukagigur volcano, SW Iceland, offers a unique exposure of a buried cinder cone within its evacuated conduit, 100 m below the main vent. The unconsolidated tephra is cross-cut by a NNE-trending dike, which runs across the ceiling of this cave to a vent that produced lava and tephra during the ~4 Ka fissure eruption. Preliminary petrographic and laser ablation inductively coupled mass spectrometry (LA-ICP-MS) analyses indicate that there are two populations of plagioclase present in the system - Population One is stubby (aspect ratio 2.1), subhedral to euhedral, and has much higher Ba/Sr ratios. Population One crystals are observed in the cinder cone, dike, and surface lavas, whereas Population Two crystals are observed only in the dike and surface lavas. This suggests that a magma crystallizing a single elongate population of plagioclase intruded the cinder cone and rapidly assimilated the tephra, incorporating the stubbier population of phenocrysts. This conceptual model for basaltic cannibalism is supported by field observations of large-scale erosion upward into the tephra, which is coated by magma flow-back indicating that magma was involved in the thermal etching. While the unique exposure at Thrihnukagigur makes it an exceptional place to investigate basaltic cannibalism, we suggest that it is not limited to this volcanic system. Rather it is a process that likely

Full Text Available It has previously been proposed that agency theory (principal-agent approach might be applied to media organizations to understand how media owners make sure that their companies are managed according to their wishes. Thus, the purpose of the present study was to investigate: a whether agency theory is applicable to three Icelandic media companies, and b how the theory manifests itself in the management practices of these companies. The media companies that were examined were: the Icelandic National Broadcasting Service (RÚV ohf., 365 miðlar ehf. and Árvakur hf. Qualitative interviews were conducted with three editors-in-chief, two CEOs/publishers, the director general of RÚV and the news director of RÚV in May of 2012. Two of the interviewees were also part- owners of the media companies. The results indicated that it is, indeed, possible to analyze management practices of media organizations from the perspective of agency theory. However, it varies how much the companies are driven by profit maximization, for instance – on which agency theory places an optimum emphasis. The media house 365 miðlar ehf. turned out to be the best example of how the underlying constructs of agency theory are incorporated into the management practices of a media organization.

Investigation on the age of mineralization in the Sungun porphyry Cu-Mo deposit, NW Iran with a regional metallogenic perspective

Science.gov (United States)

Simmonds, Vartan; Moazzen, Mohssen; Mathur, Ryan

2016-04-01

The Sungun porphyry copper deposit (PCD) is located in NW Iran, neighbouring several other PCDs and prospects in the region and the Lesser Caucasus (south Armenia). It lies on the Urumieh-Dokhtar magmatic arc (UDMA), which formed through the northeast-ward subduction of the Neo-Tethyan oceanic crust beneath the Central Iranian plate during late-Mesozoic and early-Cenozoic [1], and hosts the porphyry copper metallogenic belt of Iran. The Sungun PCD is the second largest deposit in Iran with ore reserves of about 850 Mt at 0.62 wt% Cu and 0.01 wt% Mo and probable reserves over 1Gt. The monzonitic to quartz monzonitic porphyry stock intruded the upper Cretaceous carbonates and Eocene volcano-sedimentary rocks. It produced a skarn-type mineralization at its contact zone with the carbonate rocks, as well as vast hydrothermal alteration zones and porphyry-type Cu and Mo mineralization. The zircon U-Pb age of the host porphyry stock is about 22.5±0.4 to 20.1±0.4 Ma [2]. Re-Os dating of four molybdenite separates from this PCD shows ages ranging between 22.9±0.2 to 21.7±0.2 Ma, with an average of 22.57±0.2 Ma, corresponding to the early Miocene (Aquitanian). These ages indicate that both the porphyry stock and the Cu-Mo mineralization are post-collisional events, similar to many other deposits and prospects in NW and central Iran and south Armenia, and the mineralization occurred shortly after the emplacement of the host stock, corresponding better to the ages obtained from the marginal parts of the stock. Magmatism and mineralization in Sungun coincides with the third metallogenic epoch in the Lesser Caucasus (Eocene to Miocene; [3]), though it is considerably younger than all of the dated PCDs and prospects in the south Armenia. It also postdates Cu-Mo mineralizations in the Saheb Divan (35 Ma), Qaradagh batholith (31.22±0.28 to 25.19±0.19 Ma), as well as Haft Cheshmeh PCD (28.18±0.42 to 27.05±0.37 Ma) in NW Iran, while it seems to be coeval with the Kighal

Macroeconomic conditions and population health in Iceland

Directory of Open Access Journals (Sweden)

Kristín Helga Birgisdóttir

2017-09-01

Full Text Available Background: Results from recent research on the impact of economic cycles and population health have been mixed, with results appearing to be context-sensitive. Objective: We examine the long-term relationship between economic conditions and population health in Iceland, which has experienced some economically turbulent times in the last years and decades. Methods: We use aggregate annual data for 1981‒2014. We use three aggregate indicators of economic activity to proxy the economic cycle: unemployment rate, real GDP per capita, and real GDP. Life expectancy at birth, infant mortality, and total mortality as well as four cause-specific mortality rates were used as outcome measures. Results: Our results do not suggest a statistically significant relationship between economic conditions and total mortality, infant mortality, or life expectancy. Different responses between causes of death are found, and in some instances between genders, although statistical significance is low. We do, however, find a consistent and statistically significant relationship for females aged 45‒64, where economic downturns are associated with lower all-cause mortality. Conclusions: For the time period studied we do not find a significant relationship between economic cycles and population health, where health is proxied by mortality rates, life expectancy at birth, and infant mortality. Further studies using less extreme health outcomes, such as morbidity rates, are warranted. Contribution: This type of study has not been performed using Icelandic data before and provides a comparison to research from other countries where the relationship has been explored more. Additionally, one of the contributions of this paper is to use a variety of economic indicators as proxies for economic cycles in a study examining their relationship with population health.

Full Text Available Osteochondral lesions in the joints of the distal tarsal region of young Icelandic horses provide a natural model for the early stages of osteoarthritis (OA in low-motion joints. We describe and characterise mineralised and non-mineralised osteochondral lesions in left distal tarsal region joint specimens from twenty-two 30 ±1 month-old Icelandic horses. Combinations of confocal scanning light microscopy, backscattered electron scanning electron microscopy (including, importantly, iodine staining and three-dimensional microcomputed tomography were used on specimens obtained with guidance from clinical imaging. Lesion-types were described and classified into groups according to morphological features. Their locations in the hyaline articular cartilage (HAC, articular calcified cartilage (ACC, subchondral bone (SCB and the joint margin tissues were identified and their frequency in the joints recorded. Associations and correlations between lesion-types were investigated for centrodistal joints only. In centrodistal joints the lesion-types HAC chondrocyte loss, HAC fibrillation, HAC central chondrocyte clusters, ACC arrest and ACC advance had significant associations and strong correlations. These lesion-types had moderate to high frequency in centrodistal joints but low frequencies in tarsometatarsal and talocalcaneal-centroquartal joints. Joint margin lesion-types had no significant associations with other lesion-types in the centrodistal joints but high frequency in both the centrodistal and tarsometatarsal joints. The frequency of SCB lesion-types in all joints was low. Hypermineralised infill phase lesion-types were detected. Our results emphasise close associations between HAC and ACC lesions in equine centrodistal joints and the importance of ACC lesions in the development of OA in low-motion compression-loaded equine joints.

Review on utilization and research on harbour seal (Phoca vitulina in Iceland

Directory of Open Access Journals (Sweden)

Erlingur Hauksson

2010-09-01

Full Text Available Harbour seals (Phoca vitulina have been harvested in Iceland since the first settlers arrived in the 9th century. Pups were generally netted, clubbed and harpooned until 1875 when general use of guns for hunting began. Seal-hunting has been traditional amongst the farms legal rights. Seal hunting was an important supplement to other economic resources. Harbour seal skins, salted ordried, were exported and large dataset of catch statistics is available from trading logbooks since the late 19th century. In the early 20th century catch was about 6,000. In the ‘bounty’ period 1982 – 1989, maximum catches were of 4,000 animals with about 350 hunters participated; in 2006 catches were only about 100 animals with 18 hunters. After 1989 the population continued to decline even though catches decreased markedly. Unreported by-catch in fishing gear, hunt for local consumption and shooting of seals swimming in salmon rivers estuaries may have kept the total removal from the stock above sustainable levels. A considerable Icelandic knowledge base had been compiled about the biology of the harbour seal since the late 16th century, with the first written reference in 1588-1589. In the last decades, research on various aspects of its biology and monitoring have been intensified, with focus on abundance, distribution, diet and nematode infestation. The main results show that the Icelandic harbour seal population - has declined annually about 5% in the period 1980-2006, - was most abundant on the NW-coast, - feeds mainly on sand-eels and gadoids, - and was less infected with anisakid nematodes than grey seals. Seal watching, as a low-consumptive indirect utilization, may represent a new economical opportunity if properly regulated.

A critical review of Iran's buyback contracts

International Nuclear Information System (INIS)

Groenendaal, Willem J.H. van; Mazraati, Mohammad

2006-01-01

Iran's oil and gas industry requires investments of US$ 15 billion in the short term and over US$70 billion in the medium term. Iran tries to interest international oil companies (IOC) in investing in Iran's oil and gas business by offering buyback contracts. Under a buyback contract an IOC invests and when production starts, the field is handed over to the National Iranian Oil Company (NIOC) or one of its representatives. The IOC gets its costs and an agreed upon profit paid out of the oil and/or gas gross profits, assuming the field produces as agreed upon and the international energy prices are high enough. According to the Iranian government, the buyback contract contains sufficient incentives for an IOC to invest in Iran. The IOCs, however, disagree. They claim that they solely bare the risks in a buyback contract, whereas the Iranian counterpart receives all windfall profits. Furthermore, the IOCs claim that the utilisation of Iran's oil and gas reserves will be sub-optimal if they are not involved in optimising long-term recovery. In this paper, we investigate these claims and show that they are partly correct. Given Iran's need for investment capital, Iran might have to change its policy

HACCP and water safety plans in Icelandic water supply: preliminary evaluation of experience.

Science.gov (United States)

Gunnarsdóttir, María J; Gissurarson, Loftur R

2008-09-01

Icelandic waterworks first began implementing hazard analysis and critical control points (HACCP) as a preventive approach for water safety management in 1997. Since then implementation has been ongoing and currently about 68% of the Icelandic population enjoy drinking water from waterworks with a water safety plan based on HACCP. Preliminary evaluation of the success of HACCP implementation was undertaken in association with some of the waterworks that had implemented HACCP. The evaluation revealed that compliance with drinking water quality standards improved considerably following the implementation of HACCP. In response to their findings, waterworks implemented a large number of corrective actions to improve water safety. The study revealed some limitations for some, but not all, waterworks in relation to inadequate external and internal auditing and a lack of oversight by health authorities. Future studies should entail a more comprehensive study of the experience with the use of HACCP with the purpose of developing tools to promote continuing success.

Helium isotopes in geothermal systems: Iceland, The Geysers, Raft River and Steamboat Springs

International Nuclear Information System (INIS)

Torgersen, T.

1982-01-01

Helium isotope ratios have been measured in geothermal fluids from Iceland, The Geysers, Raft River, Steamboat Springs and Hawaii. These ratios have been interpreted in terms of the processes which supply He in distinct isotopic ratios and in terms of the processes which can alter the isotopic ratio. Using this interpretational scheme, Iceland is found to be an area of hot-spot magmatic He implying an active volcanic source although the data are suggestive of high-temperature weathering release of crustal He incorporated in the geothermal fluids. By comparison to fumarolic gases from Hawaii and Juan De Fuca and Cayman Trench basaltic glass samples, The Geysers contains MOR type magmatic He again implying an active volcanic source possibly a 'leaky' transform related to the San Andreas Fault System. Raft River contains only crustal He indicating no active volcanic sources. Steamboat Springs He isotope ratios are distinctly less than typical plate margin volcanics but must still have a magmatic source. (author)

The puzzle of the 1996 Bárdarbunga, Iceland, earthquake: no volumetric component in the source mechanism

2009-01-01

A volcanic earthquake with Mw 5.6 occurred beneath the Bárdarbunga caldera in Iceland on 29 September 1996. This earthquake is one of a decade-long sequence of  events at Bárdarbunga with non-double-couple mechanisms in the Global Centroid Moment Tensor catalog. Fortunately, it was recorded well by the regional-scale Iceland Hotspot Project seismic experiment. We investigated the event with a complete moment tensor inversion method using regional long-period seismic waveforms and a composite structural model. The moment tensor inversion using data from stations of the Iceland Hotspot Project yields a non-double-couple solution with a 67% vertically oriented compensated linear vector dipole component, a 32% double-couple component, and a statistically insignificant (2%) volumetric (isotropic) contraction. This indicates the absence of a net volumetric component, which is puzzling in the case of a large volcanic earthquake that apparently is not explained by shear slip on a planar fault. A possible volcanic mechanism that can produce an earthquake without a volumetric component involves two offset sources with similar but opposite volume changes. We show that although such a model cannot be ruled out, the circumstances under which it could happen are rare.

2018-03-01

The complete genome sequence of Zucchini yellow mosaic virus strain Kurdistan (ZYMV-Kurdistan) infecting squash from Iran was determined from 13 overlapping fragments. Excluding the poly (A) tail, ZYMV-Kurdistan genome consisted of 9593 nucleotides (nt), with 138 and 211 nt at the 5' and 3' non-translated regions, respectively. It contained two open-reading frames (ORFs), the large ORF encoding a polyprotein of 3080 amino acids (aa) and the small overlapping ORF encoding a P3N-PIPO protein of 74 aa. This isolate had six unique aa differences compared to other ZYMV isolates and shared 79.6-98.8% identities with other ZYMV genome sequences at the nt level and 90.1-99% identities at the aa level. A phylogenetic tree of ZYMV complete genomic sequences showed that Iranian and Central European isolates are closely related and form a phylogenetically homogenous group. All values in the ratio of substitution rates at non-synonymous and synonymous sites ( d N / d S ) were below 1, suggestive of strong negative selection forces during ZYMV protein history. This is the first report of complete genome sequence information of the most prevalent virus in the west of Iran. This study helps our understanding of the genetic diversity of ZYMV isolates infecting cucurbit plants in Iran, virus evolution and epidemiology and can assist in designing better diagnostic tools.

Anopheles fluviatilis, one of the major malaria vectors in Iran, is assumed to be a complex of sibling species. The aim of this study was to evaluate Cytochrome oxidase I (COI) gene alongside 28S-D3 as a diagnostic tool for identification of An. fluviatilis sibling species in Iran. DNA sample belonging to 24 An. fluviatilis mosquitoes from different geographical areas in south and southeastern Iran were used for amplification of COI gene followed by sequencing. The 474-475 bp COI sequences obtained in this study were aligned with 59 similar sequences of An. fluviatilis and a sequence of Anopheles minimus, as out group, from GenBank database. The distances between group and individual sequences were calculated and phylogenetic tree for obtained sequences was generated by using Kimura two parameter (K2P) model of neighbor-joining method. Phylogenetic analysis using COI gene grouped members of Fars Province (central Iran) in two distinct clades separate from other Iranian members representing Hormozgan, Kerman, and Sistan va Baluchestan Provinces. The mean distance between Iranian and Indian individuals was 1.66%, whereas the value between Fars Province individuals and the group comprising individuals from other areas of Iran was 2.06%. Presence of 2.06% mean distance between individuals from Fars Province and those from other areas of Iran is indicative of at least two sibling species in An. fluviatilis mosquitoes of Iran. This finding confirms earlier results based on RAPD-PCR and 28S-D3 analysis.

The Study of Impacts of Water Transferring From Wet Regions To Dry Regions In Iran

Science.gov (United States)

Motiee-Homayoun, Dr.; Ghomashchi, Dr.

Iran, with a very diverse ecology and different climate has been classified as a dry- semidry region. Iran's annual average of rain-fall is about 250 mm, while this figure is more than 1000 mm in north and less than 100 mm in the south of the country. Overall, Iran's water resources are low. Rapid population growth, economic growth together with significant urban development, in recent decades, has led to underestimate high demands for water. Therefore, water shortage has been considered more obviously. Such an important scare is rather serious in central and eastern regions of the country. This problem has been determined as a serious challenge for Iran's government and national water authorities, in particular. Although, drinking water supply is only 6 percent of total water resources, due to direct socio-political impacts, drinking water supply, in both quality and quantity, is more serious and important than agricultural water demands. Accordingly, for the following reasons: 1) Desperation and diversity of geographical conditions of urban areas 2) Low access to underground water 3) Inadequate quality surface water supply Difficulties and the costs of supplying urban water in Iran have been sharply increased. Presently, due to unconstrained consuming underground water and negative balance in most under ground resources of the country, more specifically in central and eastern regions, water supply from groundwater resources is very risky and misleading. Furthermore, other reason such as rapid urban population growth and changes in people's every day life and their consumption patterns increase both water consumption and waste water in the circumstances of inadequate sewage systems, make a vast source of pollution for water resources. Due to the influence of extended See (Salty) water, in southern provinces, near to Persian Gulf, accessibility to fresh water is rather difficult and in many cases only after tens of kilometers far from the see, fresh water could be

Sea-ice conditions on the North Icelandic shelf constitute a key component for the study of the climatic gradients between the Arctic and the North Atlantic Oceans at the Polar Front between the cold East Icelandic Current delivering Polar surface water and the relatively warm Irminger Current derived from the North Atlantic Current. The variability of sea ice contributes to heat reduction (albedo) and gas exchange between the ocean and the atmosphere, and further affects the deep-water formation. However, lack of long-term and high-resolution sea-ice records in the region hinders the understanding of palaeoceanographic change mechanisms during the last glacial-interglacial cycle. Here, we present a sea-ice record back to 15 ka (cal. ka BP) based on the sea-ice biomarker IP25, phytoplankton biomarker brassicasterol and terrestrial biomarker long-chain n-alkanols in piston core MD99-2272 from the North Icelandic shelf. During the Bølling/Allerød (14.7-12.9 ka), the North Icelandic shelf was characterized by extensive spring sea-ice cover linked to reduced flow of warm Atlantic Water and dominant Polar water influence, as well as strong meltwater input in the area. This pattern showed an anti-phase relationship with the ice-free/less ice conditions in marginal areas of the eastern Nordic Seas, where the Atlantic Water inflow was strong, and contributed to an enhanced deep-water formation. Prolonged sea-ice cover with occasional occurrence of seasonal sea ice prevailed during the Younger Dryas (12.9-11.7 ka) interrupted by a brief interval of enhanced Irminger Current and deposition of the Vedde Ash, as opposed to abruptly increased sea-ice conditions in the eastern Nordic Seas. The seasonal sea ice decreased gradually from the Younger Dryas to the onset of the Holocene corresponding to increasing insolation. Ice-free conditions and sea surface warming were observed for the Early Holocene, followed by expansion of sea ice during the Mid-Holocene.

groups for some morphemes indicated that very low scores are indicative of SLI whereas high scores are uninformative. Age effects were evident in that the morphemes varied in the age at which they separate the groups most accurately. The findings of this study show that Icelandic children with SLI are somewhat more prone to making morphological errors than their TD counterparts. However, great overlap exists between the groups. The findings call into question the view that grammatical morphology is a central area of deficit in SLI. Copyright © 2016 Elsevier Inc. All rights reserved.

Icelandic ice caps, covering ~11% of the country, are known to be surging glaciers. Such process implies an important local crustal subsidence due to the large ice mass being transported to the ice edge during the surge in a few months only. In 1993-1995, a glacial surge occurred at four neighboring outlet glaciers in the southwestern part of Vatnajökull ice cap, the largest ice cap in Iceland. We estimated that ~16±1 km3 of ice have been moved during this event while the fronts of some of the outlet glaciers advanced by ~1 km.Surface deformation associated with this surge has been surveyed using Interferometric Synthetic Aperture Radar (InSAR) acquisitions from 1992-2002, providing high resolution ground observations of the study area. The data show about 75 mm subsidence at the ice edge of the outlet glaciers following the transport of the large volume of ice during the surge (Fig. 1). The long time span covered by the InSAR images enabled us to remove ~12 mm/yr of uplift occurring in this area due to glacial isostatic adjustment from the retreat of Vatnajökull ice cap since the end of the Little Ice Age in Iceland. We then used finite element modeling to investigate the elastic Earth response to the surge, as well as confirm that no significant viscoelastic deformation occurred as a consequence of the surge. A statistical approach based on Bayes' rule was used to compare the models to the observations and obtain an estimate of the Young's modulus (E) and Poisson's ratio (v) in Iceland. The best-fitting models are those using a one-kilometer thick top layer with v=0.17 and E between 12.9-15.3 GPa underlain by a layer with v=0.25 and E from 67.3 to 81.9 GPa. Results demonstrate that InSAR data and finite element models can be used successfully to reproduce crustal deformation induced by ice mass variations at Icelandic ice caps.Fig. 1: Interferograms spanning 1993 July 31 to 1995 June 19, showing the surge at Tungnaárjökull (Tu.), Skaftárjökull (Sk.) and S�

Iran's nuclear lies

International Nuclear Information System (INIS)

Dickey, Christopher

2005-01-01

Beyond the antiaircraft gun emplacements and the early-warning radar systems, and shortly before you get to the high concrete walls topped with concertina wire that surround Iran's Bushehr Nuclear Power Plant, there's a large sign announcing that the facility Welcomes guests. Like so much about die Iranian nuclear program, die signals are incongruous, contradictory and more then a little sinister. If Iran is to be believed, then the world has nothing to fear from its nuclear program. The United States, Europe, Israel, Saudi Arabia and other oil producers nearby can rest easy, because the ayatollahs have no plans to threaten the region with atomic weapons or put nukes in the hands of terrorists. If Iran is to be believed, its only goal, repeated countless times, ratified in treaties and open to inspections, is to develop a completely independent ability to make nuclear ir fuel and use it to generate electricity. But neither die United States nor Eu rope nor the United Nations is ready simply to believe Iran, at least not easily, and not without verification. Its record of concealment and deceit about its nuclear program goes back at least 20 years. Its extensive uranium-enrichment program was uncovered in detail only two years ago; its promise of 'full disclosure' and 'transparency' since then has been something considerably less. The election of a new hard-line Iranian president, Mahmoud Ahmadinejad, last month raises still more questions about how far Tehran can be trusted about its nuclear programs, if at all. Iran's concealments have been as vast as a secret underground facility at Natanz that was being readied for 50,000 centrifuges to enrich uranium when it was exposed in 2002. They have seemed as small as some undeclared milligrams of plutonium from a research laboratory. In a cat-and-mouse game reminiscent of the lead-up to the Iraq invasion in 2003, the Iranians have claimed to be cooperating while throwing up what often seem to be petty obstacles in front

Assessment of the potential respiratory hazard of volcanic ash from future Icelandic eruptions: a study of archived basaltic to rhyolitic ash samples.

The eruptions of Eyjafjallajökull (2010) and Grímsvötn (2011), Iceland, triggered immediate, international consideration of the respiratory health hazard of inhaling volcanic ash, and prompted the need to estimate the potential hazard posed by future eruptions of Iceland's volcanoes to Icelandic and Northern European populations. A physicochemical characterization and toxicological assessment was conducted on a suite of archived ash samples spanning the spectrum of past eruptions (basaltic to rhyolitic magmatic composition) of Icelandic volcanoes following a protocol specifically designed by the International Volcanic Health Hazard Network. Icelandic ash can be of a respirable size (up to 11.3 vol.% fiber-like particles were observed, but those present comprised glass or sodium oxides, and are not related to pathogenic natural fibers, like asbestos or fibrous zeolites, thereby limiting concern of associated respiratory diseases. None of the samples contained cristobalite or tridymite, and only one sample contained quartz, minerals of interest due to the potential to cause silicosis. Sample surface areas are low, ranging from 0.4 to 1.6 m 2  g -1 , which aligns with analyses on ash from other eruptions worldwide. All samples generated a low level of hydroxyl radicals (HO • ), a measure of surface reactivity, through the iron-catalyzed Fenton reaction compared to concurrently analyzed comparative samples. However, radical generation increased after 'refreshing' sample surfaces, indicating that newly erupted samples may display higher reactivity. A composition-dependent range of available surface iron was measured after a 7-day incubation, from 22.5 to 315.7 μmol m -2 , with mafic samples releasing more iron than silicic samples. All samples were non-reactive in a test of red blood cell-membrane damage. The primary particle-specific concern is the potential for future eruptions of Iceland's volcanoes to generate fine, respirable material and, thus, to

EU Enlargement: Migration flows from Central and Eastern Europe into the Nordic countries - exploiting a natural experiment

In this paper we look at migration flows from 10 Central and Eastern European Countries (CEEC) to 5 Nordic countries over the years 1985 - 2007. We exploit a natural experiment that arose from the fact that while Sweden opened its labour market from the day one of the 2004 EU enlargement......, and Finland and Iceland from year 2006, the other Nordic countries chose a transition period in relation to the "new" EU members. The results based on a differences-in-differences estimator show that the estimated effect of the opening of the Swedish, Finnish and Icelandic labour markets on migration from...... the CEECs that entered the EU in 2004 is not significantly different from zero. However, the effect of the opening of the Swedish and Finnish labour markets in 2007 on migration from the 2007 EU entrants, Bulgaria and Romania, is significantly positive. Further, we are interested in the overall effect...

To investigate the genetic variability and population structure of Echinococcus granulosus complex, 79 isolates were sequenced from different host species covering human, dog, camel, goat, sheep and cattle as of various geographical sub-populations of Iran (Northwestern, Northern, and Southeastern). In addition, 36 sequences of other geographical populations (Western, Southeastern and Central Iran), were directly retrieved from GenBank database for the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. The confirmed isolates were grouped as G1 genotype (n=92), G6 genotype (n=14), G3 genotype (n=8) and G2 genotype (n=1). 50 unique haplotypes were identified based on the analyzed sequences of cox1. A parsimonious network of the sequence haplotypes displayed star-like features in the overall population containing IR23 (22: 19.1%) as the most common haplotype. According to the analysis of molecular variance (AMOVA) test, the high value of haplotype diversity of E. granulosus complex was shown the total genetic variability within populations while nucleotide diversity was low in all populations. Neutrality indices of the cox1 (Tajima's D and Fu's Fs tests) were shown negative values in Western-Northwestern, Northern and Southeastern populations which indicating significant divergence from neutrality and positive but not significant in Central isolates. A pairwise fixation index (Fst) as a degree of gene flow was generally low value for all populations (0.00647-0.15198). The statistically Fst values indicate that Echinococcus sensu stricto (genotype G1-G3) populations are not genetically well differentiated in various geographical regions of Iran. To appraise the hypothetical evolutionary scenario, further study is needed to analyze concatenated mitogenomes and as well a panel of single locus nuclear markers should be considered in wider areas of Iran and neighboring countries.

Plasma fractionation, a useful means to improve national transfusion system and blood safety: Iran experience.

Science.gov (United States)

Cheraghali, A M; Abolghasemi, H

2009-03-01

In 1974, the government of Iran established Iranian Blood Transfusion Organization (IBTO) as national and centralized transfusion system. Since then donations of blood may not be remunerated and therapy with blood and its components are free of charges for all Iranian patients. Donations are meticulously screened through interviewing donors and lab testing the donations using serological methods. Currently, Iranian donors donate 1735 00 units of blood annually (donation index: 25/1000 population). Implementation of a highly efficient donor selection programme, including donors interview, establishment of confidential unit exclusion programme and laboratory screening of donated bloods by IBTO have led to seroprevalence rates of 0.41%, 0.12% and 0.004% for HBV, HCV and HIV in donated bloods respectively. Since 2004, IBTO has initiated a programme to enter into a contract fractionation agreement for the surplus of recovered plasma produced in its blood collecting centres. Although IBTO has used this project as a mean to improve national transfusion system through upgrading its quality assurance systems, IBTO fractionation project has played a major role in improving availability of plasma-derived medicines in Iran. During 2006-2007, this project furnished the Iran market with 44% and 14% of its needs to the intravenous immunoglobulin and albumin, respectively. Iranian experience showed that contract fractionation of plasma in countries with organized centralized transfusion system, which lack national plasma fractionation facility, in addition to substantial saving on national health resource and enhancing availability of plasma-derived medicines, could serve as a useful means to improve national blood safety profile.

Frequency, triggering factors and possible consequences of mass movements on outlet glaciers in Iceland.

Science.gov (United States)

Saemundsson, Thorsteinn; Margeirsson, Guðbjörn

2016-04-01

During the last 15 years several mass movements of various size and origin, e.g. rock avalanches, rock slides and debris slides have been observed to have fall on outlet glaciers in Iceland. This should not come as a surprise in this type of glacial environment, but in a way it does. When looking at the history only few mass movements are recorded to have fall on outlet glaciers in Iceland, during the decades before the year 2000 or since 1960. This "lack of mass movements" can be explained by the fact that fewer observations and monitoring were done in the past, but is it so or are we seeing increasing activity? Looking at the distribution of the known mass movements, two activity periods cam be identified. The former one around 1970 and the second one starting around 2000 and is still ongoing. Both of these periods are characterized by warmer climate leading to retreating phases of glaciers. Two larger mass movements are known from these two retreating periods. The former one occurred in January 1967. Then a large rockslide fell on the snout and into the glacial lake of the Steinholtsjökull outlet glacier in the northern side of the Eyjafjallajökull ice cap. The rockslide broke up the snout of the glacier and caused large floodwave bursting down the Steinholtsdalur valley transporting large volume of sediments down its path. The later one occurred in 2007, when a large rockavalanche fell on the Morsárjökull outlet glacier, in the southern side of the Vatnajökull ice cap. The avalanche debris covered around 1/5 of the glacier surface. Today the retreat and thinning of glaciers in Iceland are extremely rapid. The consequences of such a rapid retreat are e.g. unstable valley slopes surrounding the outlet glaciers, both in loose sediments and bedrock, thawing of mountain permafrost and not least formation of glacial lakes in front of the rapid retreating ice margins. Such conditions can become extremely hazardous, as seen by the above mentioned examples, both

Modelling the effects of ice-sheet activity on CO2 outgassing by Icelandic volcanoes

Glacial cycles may play a significant role in mediating the flux of magmatic CO2 between the Earth's mantle and atmosphere. In Iceland, it is thought that late-Pleistocene deglaciation led to a significant volcanic pulse, evidenced by increased post-glacial lava volumes and changes in melt chemistry consistent with depressurization. Investigating the extent to which glacial activity may have affected volcanic CO2 emissions from Iceland, and crucially over what timescale, requires detailed knowledge of how the magma system responded to the growth and collapse of the ice-sheet before and after the LGM. To investigate this, we coupled a model of magma generation and transport with a history of ice-sheet activity. Our results show that the emplacement and removal of the LGM ice-sheet likely led to two significant pulses of magmatic CO2. The first, and most significant of these, is associated with ice-sheet growth and occurs as the magma system recovers from glacial loading. This recovery happens from the base of the melting region upwards, producing a pulse of CO2 rich magma that is predicted to reach the surface around 20 ka after the loading event, close in time to the LGM. The second peak in CO2 output occurs abruptly following deglaciation as a consequence of increased rates of melt generation and transport in the shallow mantle. Although these post-glacial melts are relatively depleted in CO2, the increase in magma flux leads to a short-lived period of elevated CO2 emissions. Our results therefore suggest a negative feedback, whereby ice-sheet growth produces a delayed pulse of magmatic CO2, which, in addition to increased geothermal heat flux, may contribute towards driving deglaciation, which itself then causes further magmatism and CO2 outgassing. This model is consistent with the seismic structure of the asthenosphere below Iceland, and the established compositional and volumetric trends for sub- and post-glacial volcanism in Iceland. These trends show that

Hydatidosis, caused by Echinococcus granulosus is one of the most important zoonotic diseases, throughout most parts of the world. Hydatidosis is endemic in Iran and responsible for approximately 1% of admission to surgical wards. There are extensive genetic variations within E. granulosus and 10 different genotypes (G1–G10) within this parasite have been reported. Identification of strains is important for improvement of control and prevention of the disease. No new review article presented the situation of Echinococcus granulosus genotypes in Iran in the recent years; therefore in this paper we reviewed the different studies regarding Echinococcus granulosus genotypes in Iran.

The studied area is on the SW part of Saveh, 1:250,000 geological map, which is located in Urumieh-Dokhtar magmatic belt, Central Iran. The pixel values were computed by Principal Component Analysis (PCA method used to determine phyllic, argillic, and propylitic alteration zones. The C-A fractal model is utilized for separation of different parts of alteration zones due to their intensity. The log-log C-A plots reveal multifractal nature for phyllic, argillic, and propylitic alteration zones. The obtained results based on fractal model show that the main trend of the alteration zones is in NW-SE direction. Compared to the geological map of the study area and copper mineralizations, the alteration zones have been detected properly and correlate with the mineral occurrences, intrusive rock, and faults.

During the last 3 decades, Iran has experienced a rapid population growth and at the same time the health of Iranian people has improved greatly. This achievement was mainly due to training and availability of health manpower, well organized public health network and medical science and research improvement. In this article, we aimed to report the relevant data about the medical science and research situation in Iran and compare them with other countries. In this study, after reviewing science development and research indicators in medical sciences with participation of key stakeholders, we selected 3 main hybrid indexes consisting of "Research and Development (R&D) expenditures," "Personnel in Science and Technology sector" and "knowledge generation" for evaluation of medical science and research situation. Data was extracted from reliable databases. Over the past decade, Iran has achieved significant success in medical sciences and for the first time in 2015 based on Scopus index, Iran ranked first in the number of published scientific papers and number of citations in the region and among all Islamic countries. Also, 2% of the world's publications belong to Iran. Regarding innovation, the number of Iranian patents submitted to the United States Patent and Trademark Office (USPTO) was 3 and 43 in 2008 and 2013, respectively. In these years, the number of personnel in science and technology sectors including post graduate students, researchers and academic members in universities of medical sciences (UMSs) have increased. The female students in medical sciences field account for about twothirds of all students. Also, women comprise about one-third of faculty members. Since 5 years ago, Iran has had growth in science and technology parks. These achievements were attained in spite of the fact that research spending in Iran was still very low (0.5% of gross domestic product [GDP]) due to economic hardships and sanctions. Medical science and research development has

As a consequence the Ministry of the Environment issued a new regulation on hazard zoning due to snow avalanches and landslides in 2000, which aims to prevent people living or working within the areas most at risk until 2010. The regulation requires to carry out landslide and snow avalanche risk analyses, however, a method to calculate landslide risk adopted to Icelandic conditions is still missing. Therefore, the ultimate goal of this study is to develop such a method for landslides, focussing on debris flows and rock falls and to test it in Bíldudalur, NW-Iceland. Risk analysis, beside risk evaluation and risk management, is part of the holistic concept of risk assessment. Within this study, risk analysis is considered only, focussing on the risks to life. To calculate landslide risk, the spatial and temporal probability of occurrence of potential damaging events, as well as the distribution of the elements at risk in space and time, considering also changing vulnerabilities, must be determined. Within this study, a new raster-based approach is developed. Thus, all existent vector data are transferred into raster data using a resolution of 1m x 1m. The specific attribute data are attributed to the grid cells, resulting in specific raster data layers for each input parameter. The calculation of the landslide risk follows a function of the input parameters hazard, damage potential of the elements at risk, vulnerability, probability of the spatial impact, probability of the temporal impact and probability of the seasonal occurrence. Finally, results are upscaled to a resolution of 20m x 20m and are presented as individual risk to life and object risk to life for each process. Within the quantitative

Effect of year of birth on the breast cancer age-incidence curve in Iceland

Among different populations, the shape of the age-incidence curve for breast cancer is strongly related to the overall incidence of breast cancer in the respective population. Data are available from Iceland for the period 1911--1972. These data show that breast cancer has increased very markedly in Iceland during this period, and that as the overall incidence has risen, so the age-incidence curve has changed in shape, the relation between the shape and the overall incidence being the same as that now observed in other countries. The change in shape is shown to be explicable entirely as a cohort phenomenon, each decade of birth cohort having an age-incidence curve of similar shape, but with different overall incidence. Data from some other regions of the world indicate that many of the present differences in the shape of the age-incidence curve may be the reflection of cohort phenomena.

Full Text Available To identify the antidiabetic plants of Iran, a systematic review of the published literature on the efficacy of Iranian medicinal plant for glucose control in patients with type 2 diabetes mellitus was conducted. We performed an electronic literature search of MEDLINE, Science Direct, Scopus, Proquest, Ebsco, Googlescholar, SID, Cochrane Library Database, from 1966 up to June 2010. The search terms were complementary and alternative medicine (CAM, diabetes mellitus, plant (herb, Iran, patient, glycemic control, clinical trial, RCT, natural or herbal medicine, hypoglycemic plants, and individual herb names from popular sources, or combination of these key words. Available Randomized Controlled Trials (RCT published in English or Persian language examined effects of an herb (limited to Iran on glycemic indexes in type 2 diabetic patients were included. Among all of the articles identified in the initial database search, 23 trials were RCT, examining herbs as potential therapy for type 2 diabetes mellitus. The key outcome for antidiabetic effect was changes in blood glucose or HbA1 c, as well as improves in insulin sensitivity or resistance. Available data suggest that several antidiabetic plants of Iran need further study. Among the RCT studies, the best evidence in glycemic control was found in Citrullus colocynthus, Ipomoea betatas, Silybum marianum and Trigonella foenum graecum.

The NBI took over the issuance of banknotes in 1924; its central banking functions were defined by law (unrealistically, as the law foresaw a functioning gold standard which never was put into practice in 1927; its central banking section became financially separate in 1930; it was put under separate administration by law in 1957, and given the right, first exercised in 1960 onwards, to determine interest rates and reserve requirement in commercial banking. Among the particular points under discussion are NBI´s responsibility for other banks (none whatsoever when the country´s second bank failed in 1930; its involvement, from the early 1930s onward, in a regime of currency controls; its control of interest rates (limited and largely by persuasion as its rediscount rate was not an instrument of monetary policy; and its increasing willingness to state its own its monetary policy, even in opposition to the policy pursued by national government.Í greininni er fjallað um seðlabankahlutverk Landsbanka Íslands fram til 1961 þegar Seðlabanki Íslands varð að sjálfstæðri stofnun.

The Iceland Deep Drilling Project 4.5 km deep well, IDDP-2, in the seawater-recharged Reykjanes geothermal field in SW Iceland has successfully reached its supercritical target

Full Text Available The Iceland Deep Drilling Project research well RN-15/IDDP-2 at Reykjanes, Iceland, reached its target of supercritical conditions at a depth of 4.5 km in January 2017. After only 6 days of heating, the measured bottom hole temperature was 426 °C, and the fluid pressure was 34 MPa. The southern tip of the Reykjanes peninsula is the landward extension of the Mid-Atlantic Ridge in Iceland. Reykjanes is unique among Icelandic geothermal systems in that it is recharged by seawater, which has a critical point of 406 °C at 29.8 MPa. The geologic setting and fluid characteristics at Reykjanes provide a geochemical analog that allows us to investigate the roots of a mid-ocean ridge submarine black smoker hydrothermal system. Drilling began with deepening an existing 2.5 km deep vertical production well (RN-15 to 3 km depth, followed by inclined drilling directed towards the main upflow zone of the system, for a total slant depth of 4659 m ( ∼  4.5 km vertical depth. Total circulation losses of drilling fluid were encountered below 2.5 km, which could not be cured using lost circulation blocking materials or multiple cement jobs. Accordingly, drilling continued to the total depth without return of drill cuttings. Thirteen spot coring attempts were made below 3 km depth. Rocks in the cores are basalts and dolerites with alteration ranging from upper greenschist facies to amphibolite facies, suggesting that formation temperatures at depth exceed 450 °C. High-permeability circulation-fluid loss zones (feed points or feed zones were detected at multiple depth levels below 3 km depth to bottom. The largest circulation losses (most permeable zones occurred between the bottom of the casing and 3.4 km depth. Permeable zones encountered below 3.4 km accepted less than 5 % of the injected water. Currently, the project is attempting soft stimulation to increase deep permeability. While it is too early to speculate on the

Icelandic lake sediment is well suited to provide high-resolution, well-dated continuous archives of North Atlantic climate variability. We provide new insight into the Holocene climate evolution of Vestfirðir, NW Iceland, from a 10.3 ka multi-proxy lake sediment record from non-glacial lake Skorarvatn. Age control is derived from a combination of tephrochronology and 14C-dated macrofossils. Sediment samples were analyzed for both physical (MS, density) and biological (TC, TN, δ13C, δ15N, C/N, BSi) climate proxies, providing a sub-centennial record of aquatic bioactivity and terrestrial landscape stability, and hence, summer temperature. The lake basin was ice free by at least 10.3 ka yet the waning Icelandic Ice Sheet persisted in the catchment until 9.3 ka. The local Holocene Thermal Maximum (HTM), inferred from maximum aquatic bioactivity, spans 8.9 to 7.2 ka but was interrupted by significant cooling at 8.2 ka. In accordance with other Icelandic climate records documenting progressively cooler summers following the HTM, our record reveals reduced aquatic productivity and elevated terrestrial erosion toward the present. Superimposed on this 1st order trend are abrupt episodes of cooling, inferred from low aquatic bioactivity and/or enhanced landscape instability, at 6.4, 4.2, 3, 2.5 and 1.5 ka. Surprisingly, there is no clear indication of the Little Ice Age (LIA) in our record despite evidence for the local ice cap, Drangajökull, attaining maximum areal coverage at this time. Persistently low temperatures inferred from reduced aquatic productivity plateau at 2 ka whereas increasing terrestrial erosion ceases at 1 ka. Lack of a catchment erosion signal during the LIA may be the result of depleted catchment soils and/or perennially frozen ground preventing the mobilization of soil and vegetation. With the exception of the LIA, Skorarvatn's qualitative summer temperature record corresponds closely to summer sea surface temperature and sea ice records on the

Distinct preference of species for habitats is most often driven by long term differences in demographic rates between habitats. Estimating variation in those rates is key for developing successful conservation strategies. Stochastic events can interact with underlying variation in habitat quality in regulating demography but the opportunities to explore such interactions are rare. Whimbrels in Iceland show a strong preference for sparsely vegetated riverplains. Such habitats in Iceland face various threats, e.g., climate change, river regulation and spread of alien plant species. In this study we compared demographic parameters of breeding Whimbrels between riverplains and other habitats before, during and after volcanic eruption events to estimate the importance of the habitats for the species and the effect of ash deposit on breeding success. We found that an estimated minimum of 23% of the Icelandic population of Whimbrels and c. 10% of the world population of the species breed in riverplain habitats in Iceland. Whimbrels bred consistently at much higher densities in riverplain habitats than in other habitats and riverplains also had higher densities of pairs with fledglings although the proportion of successful breeders was similar between habitats. Predation by livestock may have had a considerable negative effect on breeding success on our study sites. Breeding was negatively affected by the volcanic activity, probably through the effects of ash on the invertebrate food supply, with breeding success being gradually worse closer to the eruption. Breeding success was equally affected by volcanism across habitats which differed in underlying habitat quality. This study gives an example of how populations can be regulated by factors which operate at different spatial scales, such as local variation in habitat quality and stochastic events which impact larger areas.

A Tale of two Systems: Poisoning Management in Iran and the United States

Full Text Available Poisoning morbidity and mortality is high in the developing world. Systems for care of poisoned patients differ markedly between countries. In this paper a comparison of two very different systems for the care of poisoned patients, is presented. Specifically, the role of poison centers and poison treatment centers in the US and Iran are contrasted. A systematic literature search was undertaken utilizing the PubMed, Scopus, and Google Scholar and the keywords “poison centers”, “treatment” “Iran” “United States of America” and 100 publications were identified. From these, relevant data were found in 23 publications. The information was double-checked and data were summarized herein.We find that the system of the care of poisoned patients relies heavily on certified poison centers in the US and that only a few hospitals have well developed medical toxicology services. In contrast, in Iran, the poison center system is somehow less developed and the care of poisoned patients is provided in centralized high volume hospital poison units.Although both the US and Iran have highly developed systems for the care of poisoned patients they are distinctly different. Comparative studies based on these systems could provide important data for developing countries with more rudimentary poison control and treatment facilities.

Full text: A senior IAEA expert team is returning from Iran after two days of discussions with Iranian officials held on 20 and 21 February 2012. The meeting followed previous discussions held on 29 to 31 January 2012. During both the first and second round of discussions, the Agency team requested access to the military site at Parchin. Iran did not grant permission for this visit to take place. Intensive efforts were made to reach agreement on a document facilitating the clarification of unresolved issues in connection with Iran's nuclear programme, particularly those relating to possible military dimensions. Unfortunately, agreement was not reached on this document. 'It is disappointing that Iran did not accept our request to visit Parchin during the first or second meetings', IAEA Director General Yukiya Amano said. 'We engaged in a constructive spirit, but no agreement was reached'. (IAEA)

In small scale societies, lethal attacks on another individual usually invite revenge by the victim's family. We might expect those who perpetrate such attacks to do so only when their own support network (mainly family) is larger than that of the potential victim so as to minimise the risk of retaliation. Using data from Icelandic family sagas, we show that this prediction holds whether we consider biological kin or affinal kin (in-laws): on average, killers had twice as many relatives as th...

Full Text Available The Bushehr city (Iran had been the center of attention in different historical periods by foreign countries and central government due to political and economic strategic position in Persian Gulf. The situation and condition of Bushehr, especially in Qajar era, caused that the city encountered the changes and reformations as a result of both inner and outer factors. So, the modernism process occurred in this city not long after it had emerged in Europe. So that, some buildings were built in the city which contained the features of modernism. This research, at first, introduces the former consulate of Britain (Sabzabad edifice and discovers when the building was built based on a historical-interpretative method. After that, the principals of modern architecture are explained from the different theorists’ stand point and also the characteristics of early modern architecture in Iran are explained. Finally, by describing the Bushehr condition in the early arrival of modernism, a qualitative and adaptive comparison has been done between Sabzabad architectural mechanism and the principals of modern architecture and its features in Iran. Thus, Sabzabad edifice is regarded as one of the first samples of modern architecture in Iran. The results of this research demonstrate the political, economic and also the architectural status of Bushehr city in the process of modernism in Iran which has been neglected by researchers and historians thus far.

Full Text Available Background: Anopheles fluviatilis, one of the major malaria vectors in Iran, is assumed to be a complex of sibling species. The aim of this study was to evaluate Cytochrome oxidase I (COI gene alongside 28S-D3 as a diagnostic tool for identification of An. fluviatilis sibling species in Iran.Methods: DNA sample belonging to 24 An. fluviatilis mosquitoes from different geographical areas in south and southeastern Iran were used for amplification of COI gene followed by sequencing. The 474–475 bp COI sequences obtained in this study were aligned with 59 similar sequences of An. fluviatilis and a sequence of Anopheles minimus, as out group, from GenBank database. The distances between group and individual sequences were calculated and phy­logenetic tree for obtained sequences was generated by using Kimura two parameter (K2P model of neighbor-join­ing method.Results: Phylogenetic analysis using COI gene grouped members of Fars Province (central Iran in two distinct clades separate from other Iranian members representing Hormozgan, Kerman, and Sistan va Baluchestan Provinces. The mean distance between Iranian and Indian individuals was 1.66%, whereas the value between Fars Province individ­uals and the group comprising individuals from other areas of Iran was 2.06%.Conclusion: Presence of 2.06% mean distance between individuals from Fars Province and those from other areas of Iran is indicative of at least two sibling species in An. fluviatilis mosquitoes of Iran. This finding confirms earlier results based on RAPD-PCR and 28S-D3 analysis.

Full Text Available Objectives: The present study aimed to assess elderly “healthy eating diet” -2005 (HED-2005 quality and its relationship to their socio-demographic variables in healthy subjects aged 60 years and over who live in the urban areas of Iran`s Markazi province. Methods & Materials: This study was a descriptive-analytic survey that included 165 elderly in the urban areas of Iran`s Markazi province. Data were obtained via a general questionnaire and three 24-hours recalls. Results: The mean of overall HEI-2005 was 54.08. Ninty-three point three percent (93.3% of subjects consumed grains, 70.9% fruits, 84.2% whole fruit, 47.9% vegetables, 12.7% dark-orange vegetables and legumes, 37% dairy products, 40% meats, 18.8% oils, 40% saturated fats, 1.8% sodium and 1.2% discretionary calories (from solid fat and added sugar in optimal levels. Besides, none of the elderly people had a sufficient intake of whole grains. The HEI-2005 total score enhanced along with the increases in education level (P<0.05, income (P<0.01 and TV watching time (P<0.05. But, age and the HEI-2005 total score had an inverse relationship (P<0.001. Conclusion: Because the diet quality of elderly people in the urban areas of Iran`s Markazi province is low, they will benefit from the improvement of their diet quality. Also, they need to increase intakes of whole grains, dark-orange vegetables and legumes and plant oils, and reduce intakes of sodium and their energy levels from saturated fat and simple sugar. It should be pointed out that the government can help with the achievement of these objectives through some plans such as promoting their literacy level, income and nutritional knowledge.
