    2000-01-01

    The magnetic and electrical properties are reported in the new solid solutions BaCo 1-x Cu x S 2 and BaNi 1-x Fe x S 2 . Both compounds show spin-glass-like behavior, although the type of spin frustrations is different with each other. BaCo 1-x Cu x S 2 shows a competition type spin-glass behavior with reentrant phenomenon from antiferromagnetic to spin-glass at low temperatures. BaNi 1-x Fe x S 2 shows a dilute type spin-glass behavior together with super-paramagnetic properties. The temperature variation of 57 Fe Moessbauer spectra in BaNi 0.8 Fe 0.2 S 2 is explicable in a framework of cluster-glass. (author)

    By means of Shubnikov-de Haas and de Haas-van Alphen oscillations, and ab initio calculations, we have studied the Fermi surface of high-quality BaNiS2 single crystals, with mean free path l ˜400 Å . The angle and temperature dependence of quantum oscillations indicates a quasi-two-dimensional Fermi surface, made of an electronlike tube centered at Γ , and of four holelike cones, generated by Dirac bands, weakly dispersive in the out-of-plane direction. Ab initio electronic structure calculations, in the density functional theory framework, show that the inclusion of screened exchange is necessary to account for the experimental Fermi pockets. Therefore, the choice of the functional becomes crucial. A modified HSE hybrid functional with 7% of exact exchange outperforms both GGA and GGA +U density functionals, signaling the importance of nonlocal screened-exchange interactions in BaNiS2, and, more generally, in 3 d compensated semimetals.

    Full Text Available This paper examines the role of the prophet Muhammad's preaching in resolving internal conflicts of Quraysh tribe and conflicts between the Quraysh tribe with a descendant of Mustaliq. The goal is to reconstruct their conflicts and Muhammad's position in the middle of the conflict. For that purpose, the data collected from the books of Sirah Nabawiyah as the main source and analyzed so that it can be drawn the conflict relationship between the two tribes and the resolution. The results of the study found the conflict between the Quraysh tribe of the descendant of Mustaliq can be tracked since their ancestors, respectively, before the advent of Muhammad. Fundamental issues regarding with conflicts dealing with political power, self-esteem and group identity. The triggers of conflict that almost rising the violent conflicts between the other were a misunderstanding. In resolving the conflict, the prophet prefers peaceful means despite ever using violence in the form of war. Tulisan ini mengkaji peran dakwah nabi Muhammad dalam menyelesaikan konflik intern suku Quraish maupun konflik antara suku Quraish dengan bani Mustaliq. Tujuannya, merekonstruksi relasi konflik antara mereka dan posisi Muhammad di tengah tengah konflik tersebut. Untuk tujuan itu, data dihimpun dari kitab-kitab Sirah Nabawiyah sebagai sumber utama dan dianalisis sehingga tergambar relasi-konflik tokoh-tokoh dari kedua suku tersebut dan penyelesaiannya. Hasil kajian menemukan, konflik antara suku Quraish dengan bani Mustaliq dapat dilacak sejak nenek moyang mereka masing-masing, sebelum kenabian Muhammad. Issu pokok terjadinya konflik berkenaan dengan persoalan politik kekuasaan, harga diri dan identitas kelompok. Pemicu konflik yang nyaris menimbulkan kekerasan antara lain adalah kesalahpahaman. Dalam menyelesaikan konflik, nabi lebih mengutamakan jalan damai meski pernah menggunakan kekerasan dalam bentuk

  6. Investigation of the spin-1 honeycomb antiferromagnet BaNi2V2O8 with easy-plane anisotropy

    The magnetic properties of the two-dimensional, S =1 honeycomb antiferromagnet BaNi2V2O8 have been comprehensively studied using dc susceptibility measurements and inelastic neutron scattering techniques. The magnetic excitation spectrum is found to be dispersionless within experimental resolution between the honeycomb layers, while it disperses strongly within the honeycomb plane where it consists of two gapped spin-wave modes. The magnetic excitations are compared to linear spin-wave theory allowing the Hamiltonian to be determined. The first- and second-neighbor magnetic exchange interactions are antiferromagnetic and lie within the ranges 10.90 meV ≤Jn≤13.35 meV and 0.85 meV ≤Jn n≤1.65 meV, respectively. The interplane coupling Jout is four orders of magnitude weaker than the intraplane interactions, confirming the highly two-dimensional magnetic behavior of this compound. The sizes of the energy gaps are used to extract the magnetic anisotropies and reveal substantial easy-plane anisotropy and a very weak in-plane easy-axis anisotropy. Together these results reveal that BaNi2V2O8 is a candidate compound for the investigation of vortex excitations and Berezinsky-Kosterliz-Thouless phenomenon.

  7. Multi-Site Validation of the SWAT Model on the Bani Catchment: Model Performance and Predictive Uncertainty

    2016-04-01

    Full Text Available The objective of this study was to assess the performance and predictive uncertainty of the Soil and Water Assessment Tool (SWAT model on the Bani River Basin, at catchment and subcatchment levels. The SWAT model was calibrated using the Generalized Likelihood Uncertainty Estimation (GLUE approach. Potential Evapotranspiration (PET and biomass were considered in the verification of model outputs accuracy. Global Sensitivity Analysis (GSA was used for identifying important model parameters. Results indicated a good performance of the global model at daily as well as monthly time steps with adequate predictive uncertainty. PET was found to be overestimated but biomass was better predicted in agricultural land and forest. Surface runoff represents the dominant process on streamflow generation in that region. Individual calibration at subcatchment scale yielded better performance than when the global parameter sets were applied. These results are very useful and provide a support to further studies on regionalization to make prediction in ungauged basins.

  8. Low-temperature magnetothermal transport investigation of a Ni-based superconductor BaNi2As2: evidence for fully gapped superconductivity.

    We have performed low-temperature specific heat and thermal conductivity measurements of the Ni-based superconductor BaNi2As2 (T{c}=0.7 K) in a magnetic field. In a zero field, thermal conductivity shows T-linear behavior in the normal state and exhibits a BCS-like exponential decrease below T{c}. The field dependence of the residual thermal conductivity extrapolated to zero temperature is indicative of a fully gapped superconductor. This conclusion is supported by the analysis of the specific heat data, which are well fit by the BCS temperature dependence from T{c} down to the lowest temperature of 0.1 K.

    The order-disorder phase formation of the complex perovskite compounds Ba(Ni 1/3 Nb 2/3 )O 3 (BNN) and Ba(Zn 1/3 Nb 2/3 )O 3 (BZN) was investigated using X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and energy-dispersive spectroscopy. The BNN and BZN samples were sintered over a temperature range of 1,200 to 1,500 C in air for 2 h. X-ray diffraction and transmission electron microscopy showed that these compounds exhibited a 1:2 ordering on the B-site within a narrow temperature range. When BNN and BZN were sintered above 1,400 and 1,350 C, respectively, a liquid phase formed in the grain boundary which was accompanied by disordering. The composition of the liquid phase resembled that of pyrochlore, with a small amount of nickel for BNN or zinc for BZN. The disordering with the formation of the liquid phase was attributed to the increase in defect concentration

    This medium-sized dabbling duck of slender, elegant lines and conservative plumage coloration is circumpolar in distribution and abundant in North America, with core nesting habitat in Alaska and the Prairie Pothole Region of southern Canada and the northern Great Plains. Breeders favor shallow wetlands interspersed throughout prairie grasslands or arctic tundra. An early fall migrant, the species arrives on wintering areas beginning in August, after wing molt, often forming large roosting and feeding flocks on open, shallow wetlands and flooded agricultural fields. The birds consume grains, marsh plant seeds, and aquatic invertebrates throughout fall and winter.Northern Pintails are among the earliest nesting ducks in North America, beginning shortly after ice-out in many northern areas. Individuals form new pair bonds each winter but are highly promiscuous during the nesting season, with mated and unmated males often involved in vigorous, acrobatic Pursuit Flights. Annual nest success and productivity vary with water conditions, predation, and weather. Females build nests on the ground, often far from water. Only the female incubates; her mate leaves shortly after incubation begins. Ducklings hatch together in one day, follow the female to water after a day in the nest, and fledge by July or August. Adults and ducklings consume mainly aquatic invertebrates during the breeding season.Predators and farming operations destroy many thousands of Northern Pintail nests annually; farming has also greatly reduced the amount of quality nesting cover available. Winter habitats are threatened by water shortages, agricultural development, contamination, and urbanization. Periods of extended drought in prairie nesting regions have caused dramatic population declines, usually followed by periods of recovery. Over the long term, however, the continental population of Northern Pintails has declined significantly from 6 million birds in the early 1970s to less than 3 million in

  18. Northern Ireland: an anomaly.

    Simpson, A

    1989-01-01

    The British Abortion Act of 1967, which makes abortion legal up to 28 weeks, does not extend to Northern Ireland, where abortion is still regulated by the 1861 Offences Against the Person Act, which makes abortion a felony, and the 1929 Infant Life Preservation Act, which prohibits abortion after the 28th week of pregnancy. The Bourne Judgment of 1928, in which a court held in favor of one Dr. Alex Bourne, who performed an early abortion, may be cited as precedent, but not as law. A woman in Northern Ireland may have an abortion only on the National Health Service and only if pregnancy is life-threatening, if she is mentally retarded, or if the child is likely to be abnormal. How many abortions are actually performed in Northern Ireland each year is not known. Essentially, women with unwanted pregnancies have only 3 options: to have the baby, to risk a back street abortion, and to go to England. Since 1967, 20,000 Northern Irish women have had abortions in England, but it is a privilege reserved for the wealthy because the woman must bear the expenses of traveling to England, establishing residency there, and paying hospital fees. All of this takes time and results in many women having late abortions. The women also must bear the stigma of having done something of which neither church in Northern Ireland approves. Northern Irish women, quite simply, do not have the same rights as women in England, Scotland, and Wales.

    10 December 2004 The lower left (southwest) corner of this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the location of a somewhat filled and buried meteor impact crater on the northern plains of Mars. The dark dots are boulders. A portion of a similar feature is seen in the upper right (northeast) corner of the image. This picture, showing landforms (including the odd mound north/northeast of the crater) that are typical of the martian northern lowland plains, was obtained as part of the MGS MOC effort to support the search for a landing site for the Phoenix Mars Scout lander. Phoenix will launch in 2007 and land on the northern plains in 2008. This image is located near 68.0oN, 227.4oW, and covers an area approximately 3 km (1.9 mi) wide. The scene is illuminated by sunlight from the lower left.

  7. Northern pipelines : backgrounder

    International Nuclear Information System (INIS)

    2002-04-01

    Most analysts agree that demand for natural gas in North America will continue to grow. Favourable market conditions created by rising demand and declining production have sparked renewed interest in northern natural gas development. The 2002 Annual Energy Outlook forecasted U.S. consumption to increase at an annual average rate of 2 per cent from 22.8 trillion cubic feet to 33.8 TCF by 2020, mostly due to rapid growth in demand for electric power generation. Natural gas prices are also expected to increase at an annual average rate of 1.6 per cent, reaching $3.26 per thousand cubic feet in 2020. There are currently 3 proposals for pipelines to move northern gas to US markets. They include a stand-alone Mackenzie Delta Project, the Alaska Highway Pipeline Project, and an offshore route that would combine Alaskan and Canadian gas in a pipeline across the floor of the Beaufort Sea. Current market conditions and demand suggest that the projects are not mutually exclusive, but complimentary. The factors that differentiate northern pipeline proposals are reserves, preparedness for market, costs, engineering, and environmental differences. Canada has affirmed its role to provide the regulatory and fiscal certainty needed by industry to make investment decisions. The Government of the Yukon does not believe that the Alaska Highway Project will shut in Mackenzie Delta gas, but will instead pave the way for development of a new northern natural gas industry. The Alaska Highway Pipeline Project will bring significant benefits for the Yukon, the Northwest Territories and the rest of Canada. Unresolved land claims are one of the challenges that has to be addressed for both Yukon and the Northwest Territories, as the proposed Alaska Highway Pipeline will travel through traditional territories of several Yukon first Nations. 1 tab., 4 figs

    2007-01-01

    A series of tornadoes ripped through the Upper Midwest region of the United States in the evening of June 7, 2007. At least five different tornadoes touched down in Wisconsin, according to the Associated Press, one of which tore through the Bear Paw Resort in northern Wisconsin. Despite dropping as much as fifteen centimeters (six inches) of rain in some places and baseball-size hail in others, authorities were reporting no deaths attributable to the storm system, and only a smattering of injuries, but considerable property damage in some areas. When the MODIS instrument on NASA's Terra satellite observed the area on June 9, 2007, the track torn through the woods by one of the tornadoes stands out quite clearly. This photo-like image uses data collected by MODIS in the normal human vision range to give a familiar natural-looking appearance. The landscape is largely a checkerboard of farms, towns, roads, and cities. The pale land is predominantly farmland where crops have not fully grown in yet. Dark blue shows the winding path of rivers and lakes dotting the landscape. The large blue lake on the east (right) side of the image is Lake Michigan. Towns and cities, including the city of Green Bay, are gray. To the north side, farmland gives way to dark green as land use shifts from agriculture to the Menominee Indian Reservation and Nicolet National Forest. The diagonal slash through the dark green forested land shows the tornado track. Bare land was revealed where the tornado tore down trees or stripped vegetation off the branches. The high-resolution image provided above is at MODIS' full spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Until recently, this feature that we have termed 'the haystack,' has been seen persistently at high northern latitudes with the Composite Infrared Spectrometer (CIRS) instrument onboard Cassini, The strength of the haystack emission feature diminishes rapidly with season, becoming drastically reduced at high northern latitudes, as Titan transitions from northern winter into spring, In contrast to IRIS whose shortest wavenumber was 200 per centimeter, CIRS extends down to 10 per centimeter, thus revealing an entirely unexplored spectral region in which nitrile ices have numerous broad lattice vibration features, Unlike the haystack, which is only found at high northern latitudes during northern winter/early northern spring, this geometrically thin nitrile cloud pervades Titan's lower stratosphere, spectrally peaking at 160 per centimeter, and is almost global in extent spanning latitudes 85 N to 600 S, The inference of nitrile ices are consistent with the highly restricted altitude ranges over which these features are observed, and appear to be dominated by a mixture of HCN and HC3N, The narrow range in altitude over which the nitrile ices extend is unlike the haystack, whose vertical distribution is significantly broader, spanning roughly 70 kilometers in altitude in Titan's lower stratosphere, The nitrile clouds that CIRS observes are located in a dynamically stable region of Titan's atmosphere, whereas CH4 clouds, which ordinarily form in the troposphere, form in a more dynamically unstable region, where convective cloud systems tend to occur. In the unusual situation where Titan's tropopause cools significantly from the HASI 70.5K temperature minimum, CH4 should condense in Titan's lower stratosphere, just like the aforementioned nitrile clouds, although

    1991-01-01

    An extensive review is presented on petroleum and chlorinated hydrocarbon pollution in waters and marine organisms of the North Atlantic and of the North, Baltic, Norwegian, and Barents Seas. Data are presented on the bioaccumulation of those pollutants in the organs and tissues of sea birds and of marine biota at various trophic levels. The effects of pollutants on plankton in northern seas are discussed. Factors affecting the bioaccumulation of toxic substances in fish are also examined. It has been discovered that residual quantities of polychlorinated biphenyls, chlorinated pesticides and their metabolites, and petroleum hydrocarbons are present everywhere at all water levels in northern seas. Of particular concern is the fact that maximum concentrations of contaminants have been recorded in the most productive regions, including shelf and estuary zones, the euphotic zone, and areas of upwelling. Both individual toxic substances and their combinations disrupt normal functioning of ecosystems in northern seas, causing a change in the level of primary production and a decline in fish productivity. Pollutant accumulation in commercially valuable organisms represents a serious threat to human health. 424 refs., 13 figs., 15 tabs

    Stevanovic, Zoran; Iurkiewicz, Adrian

    2009-03-01

    Groundwater is vital and the sole resource in most of the studied region of northern Iraq. It has a significant role in agriculture, water supply and health, and the elimination of poverty in rural areas. Although Iraq is currently dramatically disturbed by complex political and socio-economic problems, in its northern part, i.e. the Kurdish-inhabited region, fast urbanization and economic expansion are visible everywhere. Monitoring and water management schemes are necessary to prevent aquifer over-exploitation in the region. Artificial recharge with temporary runoff water, construction of subsurface dams and several other aquifer management and regulation measures have been designed, and some implemented, in order to improve the water situation. Recommendations, presented to the local professionals and decision-makers in water management, include creation of Water Master Plans and Water User Associations, synchronization of drilling programmes, rehabilitation of the existing well fields, opening of new well fields, and the incorporation of new spring intakes in some areas with large groundwater reserves, as well as construction of numerous small-scale schemes for initial in situ water treatment where saline groundwater is present.

    Full Text Available This paper is concerned with the identification of different influences on the built environment, and those which have a physical and psychological impact on people. The aim of this study is to analyze the impact of the built environment on the lives of people. The interrelationship between people and built environment is based on human perception. This research will explore this relationship further in order to develop a clear understanding of the ways in which architecture may influence peoples’ perceptions and experiences. Additionally, the research entails a comparison between two important theories: the first is an Image of the city derived using the Mental Map Theory; the second is related to Space Syntax Theory. The two theories will be applied in two different cities in Libya with the aim of assessing the importance of their interrelationship and how it may be understood more clearly. This paper will also provide guidelines for improving urban design and planning standards with the end goal of producing a high quality perception by those who actually use the space. Moreover, it concludes with a number of research avenues that should be pursued to answer how the properties of built environment affect human perception.

    Full Text Available Based on LANDSAT ETM and Digital Elevation Model (DEM data derived by the Shuttle Radar Topography Mission (SRTM, 2000 of the coastal areas of Northern Venezuela were investigated in order to detect traces of earlier tsunami events. Digital image processing methods used to enhance LANDSAT ETM imageries and to produce morphometric maps (such as hillshade, slope, minimum and maximum curvature maps based on the SRTM DEM data contribute to the detection of morphologic traces that might be related to catastrophic tsunami events. These maps combined with various geodata such as seismotectonic data in a GIS environment allow the delineation of coastal regions with potential tsunami risk. The LANDSAT ETM imageries merged with digitally processed and enhanced SRTM data clearly indicate areas that might be prone by flooding in case of catastrophic tsunami events.

  5. Increasing Northern Hemisphere water deficit

    Science.gov (United States)

    McCabe, Gregory J.; Wolock, David M.

    2015-01-01

    A monthly water-balance model is used with CRUTS3.1 gridded monthly precipitation and potential evapotranspiration (PET) data to examine changes in global water deficit (PET minus actual evapotranspiration) for the Northern Hemisphere (NH) for the years 1905 through 2009. Results show that NH deficit increased dramatically near the year 2000 during both the cool (October through March) and warm (April through September) seasons. The increase in water deficit near 2000 coincides with a substantial increase in NH temperature and PET. The most pronounced increases in deficit occurred for the latitudinal band from 0 to 40°N. These results indicate that global warming has increased the water deficit in the NH and that the increase since 2000 is unprecedented for the 1905 through 2009 period. Additionally, coincident with the increase in deficit near 2000, mean NH runoff also increased due to increases in P. We explain the apparent contradiction of concurrent increases in deficit and increases in runoff.

  6. Case studies: Northern Saskatchewan, Canada

    International Nuclear Information System (INIS)

    2009-01-01

    Northern Saskatchewan comprises an area of about 350 000 km 2 . In 1951 the population was 11 000 people but by 2003 it was approaching 40 000, of whom about 87% are aboriginal, consisting of either First Nations or Metis people. The first uranium mining area developed in northern Saskatchewan was Uranium City, north of Lake Athabasca. These first mines started production in the early 1950s. Of the 10 producing mines, only Eldorado Nuclear remained in operation after 1965. The development of Uranium City, including better services such as a hospital, drew some aboriginals into the area. There was some aboriginal employment in the early mines but, with few exceptions, these employees only stayed a short time. The mining companies developed training programmes to prepare aboriginals for regular, wage earning jobs. This included lifestyle training such as how to manage personal finances. Further extensive training programmes were required on the job to help these employees become fully contributing members of the workforce, who could advance in their jobs, expand their job opportunities and earnings, and in order to reduce turnover. The question of accommodating mine staff is a complex one, including several options. The first option, a company town, can be developed adjacent to the mine site. It is owned by the company and accommodates everyone who works at the mine and in its service industries. This can result in lower cost accommodation for mine staff with the benefit of no personal capital investment that cannot be recouped after mine closure. The capital cost to the mining company is higher; there is an administrative cost to managing and maintaining many houses, apartments and bunkhouses, and the decommissioning problem at the end of mine life is bigger. Initial developments in northern Saskatchewan were based on the company town concept. At the time there were 25 or more advanced exploration projects in the Uranium City area, 10 of which developed into

  7. Bioactive compounds from northern plants.

    Science.gov (United States)

    Hohtola, Anja

    2010-01-01

    Northern conditions are characterised by long days with much light and low temperatures during the growing season. It has been chimed that herbs and berries grown in the north are stronger tasting compared to those of southern origin. The compounds imparting aroma and color to berries and herbs are secondary metabolites which in plants mostly act as chemical means of defense. Recently, the production of secondary metabolites using plant cells has been the subject of expanding research. Light intensity, photoperiod and temperature have been reported to influence the biosynthesis of many secondary metabolites. Native wild aromatic and medicinal plant species of different families are being studied to meet the needs of raw material for the expanding industry of e.g., health-promoting food products known as nutraceutics. There are already a large number of known secondary compounds produced by plants, but the recent advances in modern extraction and analysis should enable many more as yet unknown compounds to be found, characterised and utilised. Rose root (Rhodiola rosea) is a perennial herbaceous plant which inhabits mountain regions throughout Europe, Asia and east coastal regions of North America. The extract made from the rhizomes acts as a stimulant like the Ginseng root. Roseroot has been categorized as an adaptogen and is reported to have many pharmacological properties. The biologically active components of the extract are salitroside tyrosol and cinnamic acid glycosides (rosavin, rosarin, rosin). Round-leaved sundew (Drosera rotundifolia L.) has circumboreal distribution. It inhabits nutrient-poor, moist and sunny areas such as peat bogs and wetlands. Sundew leaves are collected from the wild-type for various medicinal preparations and can be utilized in treating e.g., as an important "cough-medicine" for different respiratory diseases. The antimicrobial activity of extracts of aerial parts against various bacteria has been investigated. Drosera produces

  9. Roman whetstone production in northern Gaul (Belgium and northern France

    Directory of Open Access Journals (Sweden)

    Aurélie Thiébaux

    2016-10-01

    Full Text Available This paper focuses on the latest research on the production of Roman whetstones in northern Gaul. To date, little has been written about this specialised industry. However, three workshops producing whetstones were discovered recently in the north of Gaul in Buizingen (Province of Flemish Brabant, Belgium, Nereth (Province of Liège, Belgium and Le Châtelet-sur-Sormonne (Department of Ardennes, France. Production debris and rough-outs recovered at these sites allowed us to reconstruct the operational sequence of manufacture, from the choice of raw material to the finished product. Technological studies enabled us to determine the production stages and highlight the similarities and differences between the three study areas. Analyses of the materials reveal the use of fine-grained sedimentary and low-grade metamorphic rocks outcropping near the workshops. All these rocks are linked to the Caledonian inliers of Brabant-London, Stavelot-Venn, and Rocroi. The large amount of waste found at Le Châtelet-sur-Sormonne, far more than that recovered at Buizingen and Nereth, is indicative of the economic importance of this whetstone workshop. This importance is reflected in the fact that whetstones from Le Châtelet-sur-Sormonne are distributed over a large area throughout Belgium, France (Nord-Pas-de-Calais, Picardie and Champagne-Ardenne regions, Germany, and the Netherlands. This paper presents the waste and rough-outs from the three production sites. It also defines rock types and their origins and offers insights into whetstone manufacturing processes and techniques.

The following diseases are discussed: bovine viral diarrhoea/mucosal disease (BVD/MD, alphaherpesvirus infections, malignant catarrhal fever (MCF, poxvirus infections, parainfluenza type 3 virus infection, Alvsborg disease, foot-and-mouth disease, epizootic haemorrhage disease of deer and bluetongue disease, rabies, respiratory syncytial virus infection, adenovirus infection, hog-cholera, Aujeszky's disease and equine herpesvirus infections. There are no significant differences in antibody prevalence to BVDV among deer in habitats with high, intermediate and low density of cattle. In addition, sequence analysis from the BVDV isolated from roe deer (Capreolus capreolus showed that this strain was unique within BVDV group I. Distinct BVDV strains might circulate in free-ranging roe deer populations in Germany and virus transmission may be independent of domestic livestock. Similar results have been obtained in a serological survey of alpha-herpesviruses in deer in Germany. Malignant catarrhal fever was studied in fallow deer (Cervus dama in Germany: the seroprevalence and positive PCR results detected in sheep originating from the same area as the antibody-positive deer might indicate that sheep are the main reservoir animals. Contagious ecthyma (CE is a common disease in domestic sheep and goats caused by the orf virus. CE has been diagnosed in Rocky Mountain bighorn sheep (Ovis canadensis, mountain goats (Oreamnos americanus, Dall sheep (Ovis dalli, chamois (Rupkapra rupi-capra, muskox {Ovibos moschatus and reindeer (Rangifer tarandus. Most parainfluenza type 3 virus infections are mild or clinically undetectable. Serological surveys in wildlife have been successfully conducted in many species. In 1985, a new disease was identified in Swedish moose (Alces alces, designated as Alvsborg disease. This wasting syndrome probably

  20. Climatic variability, plant phenology, and northern ungulates

    Models of climate change predict that global temperatures and precipitation will increase within the next century, with the most pronounced changes occurring in northern latitudes and during winter. A large-scale atmospheric phenomenon, the North Atlantic Oscillation (NAO), is a strong determinant of both interannual variation and decadal trends in temperatures and precipitation during winter in northern latitudes, and its recent persistence in one extreme phase may be a substantial component of increases in global temperatures. Hence, the authors investigated the influences of large-scale climatic variability on plant phenology and ungulate population ecology by incorporating the NAO in statistical analyses of previously published data on: (1) the timing of flowering by plants in Norway, and (2) phenotypic and demographic variation in populations of northern ungulates. The authors analyzed 137 time series on plant phenology for 13 species of plants in Norway spanning up to 50 yr and 39 time series on phenotypic and demographic traits of 7 species of northern ungulates from 16 populations in North America and northern Europe spanning up to 30 yr.

    Manitoba Hydro is about to embark on a major construction project in the northern part of the province. Important considerations involved in this project include purchasing the necessary materials, products, and services, and employing a suitable work force. An outline is presented of draft policies being considered by Manitoba Hydro to enhance northern-aboriginal and northern participation in its future development projects in northern Manitoba. The policies are presented in four sections: purchasing for northern construction and operation activities; training and employment for construction of a generation station and expansion of a converter station; training and employment for construction of a major north-south transmission line; and training and employment for northern operations and maintenance work at existing facilities. Aspects of these policies include giving preference in purchasing to northern and aboriginal businesses, training initiatives and employee counselling for aboriginal employees, and hiring preferences directed toward northern aboriginals and northern residents

    2017-12-01

    This article is a contribution to the study of the indigenous navigation and its boats in the region of northern Patagonia. This article also aims to contribute to the understanding of indigenous navigation practices and technologies and their origins from prehistoric times to the mid-twentieth century. It presents and discusses the concept of Westerdahl's Maritime Cultural Landscape in relation to other landscape concepts. This model is applied to northern Patagonia in order to discuss if it is possible to speak of a true maritime culture in the region. For this purpose, archaeological, historical and ethnographic data are presented in an integrative and innovative methodology for the discipline. Finally, the Maritime Cultural Landscape model will allow the integration of aquatic and terrestrial landscapes as routes traveled by native inhabitants of northern Patagonia and southern Chile, and propose an important and diversified maritime, river and lake tradition.

    The evolution of a warm water mass related to the Iberian Poleward Current (IPC) was characterized along the northern Galician shelf in November 2008 by means of Sea Surface Temperature and wind data. It was observed that under upwelling favorable conditions water temperature decreased along the northern coast and a temperature break appeared between Cape Vilano and Cape Ortegal showing a relaxation of the poleward intrusion. The effect of the IPC was also analyzed inside the Northern Galician Rias taking into account the hydrographical and biogeochemical properties measured on November 18. Water driven by the IPC was observed close to the mouth of the rias, around Cape Estaca de Bares, causing a nutrient salts decrease. Inside the rias a slight biological activity was found near surface resulting from fluvial contributions.

    Understanding the implications of climate change on northern Canada requires a background about the size and diversity of its human and biogeophysical systems. Occupying an area of almost 40% of Canada, with one-third of this contained in Arctic islands, Canada's northern territories consist of a diversity of physical environments unrivaled around the circumpolar north. Major ecozones composed of a range of landforms, climate, vegetation, and wildlife include: Arctic, boreal and taiga cordillera; boreal and taiga plains; taiga shield; and northern and southern Arctic. Although generally characterized by a cold climate, there is an enormous range in air temperature with mean annual values being as high as -5 degrees C in the south to as low as -20 degrees C in the high Arctic islands. A similar contrast characterizes precipitation, which can be > 700 mm y(-1) in some southern alpine regions to as low as 50 mm y(-1) over islands of the high Arctic. Major freshwater resources are found within most northern ecozones, varying from large glaciers or ice caps and lakes to extensive wetlands and peat lands. Most of the North's renewable water, however, is found within its major river networks and originates in more southerly headwaters. Ice covers characterize the freshwater systems for multiple months of the year while permafrost prevails in various forms, dominating the terrestrial landscape. The marine environment, which envelops the Canadian Arctic Archipelago, is dominated by seasonal to multiyear sea ice often several meters thick that plays a key role in the regional climate. Almost two-thirds of northern Canadian communities are located along coastlines with the entire population being just over 100 000. Most recent population growth has been dominated by an expansion of nonaboriginals, primarily the result of resource development and the growth of public administration. The economies of northern communities, however, remain quite mixed with traditional land

    The present report is part of an ongoing study by the Swiss Seismological Service, that was initiated by Nagra almost 20 years ago. It is devoted to the detailed monitoring of the earthquake activity in northern and central Switzerland. The main objective of this study is to provide information about the locations of active deformation and the state of stress in the Earth's crust and to relate these to the geological features visible at the surface. Originally, this seismotectonic investigation was restricted to the northern part of Switzerland; later it was extended also to the central part. Concerning the seismotectonics of northern Switzerland, this report constitutes a continuation of earlier publications. Here we review the seismic activity and earthquake focal mechanisms of the last 10 years and subsequently derive a comprehensive picture of the deformation and stress in the Earth's crust of northern Switzerland, based on all data available up to the end of 1999. Concerning the seismotectonics of central Switzerland, this publication constitutes the first publicly available report. (author) [de

    Full Text Available Abstract: In societies in conflict the role of the media is supposed to be neutral and to report conflicts fairly and with balanced analyses. By their public debates on conflicts they are also supposed to take part in pacifying societies and in helping to bring peace. Cottle (1997, for instance, explained that even though some findings related to the British media and its reporting of the Northern Ireland conflict were relevant, he argued that they needed revision. Consequently, he proposed new paradigms of media studies. Elliott (1977 and Curtis(1996 showed that the British media concentrated on violence in general and on republican violence in particular. Moreover, they argued that the British media neglected social and political contexts in their reporting of the conflict. The aim of this paper is then to examine some aspects of how the British media cover the Northern Ireland conflict. We studied the coverage of the Northern Ireland conflict by The (London Times (1990-1995. We used a discourse analysis method to study the paper’s discourse structure in its representation of the Northern Ireland conflict.

    Seasonal prevailing surface winds are analyzed in the territory of Northern Serbia, using observational data from 12 meteorological stations over several decades. In accordance with the general definition of prevailing wind, two special definitions of this term are used. The seasonal wind roses in 16 directions at each station are analyzed. This study shows that the prevailing winds in Northern Serbia have northwestern and southeastern directions. Circulation weather types over Serbia are presented in order to determine the connections between the synoptic circulations and prevailing surface winds. Three controlling pressure centers, i.e., the Mediterranean cyclone, Siberian high, and the Azores anticyclone, appear as the most important large-scale factors that influence the creation of the prevailing winds over Northern Serbia. Beside the synoptic cause of the prevailing winds, it is noted that the orography of the eastern Balkans has a major influence on the winds from the second quadrant. It was found that the frequencies of circulation weather types are in agreement with those of the prevailing winds over Northern Serbia.

    Offshore winds are investigated in detail in the EU- Norsewind project - short for Northern Seas Wind Index Database - that aims to produce an offshore wind atlas for the Northern European Seas including the Baltic Sea, the North Sea and the Irish Sea. The results are preliminary as they are from mid-term in the project (2008-2012). The results include mean wind speeds from Envisat ASAR, QuikSCAT and SSM/I compared to masts. The spatial variability across the area is clearly identified with major coastal effects in the enclosed seas. The long-term trend analysis does not indicate any trend in the different wind speed bins investigated during 23 years. The next step is further comparison to ground-based lidar data and atmospheric model results.

    Peatlands cover large areas in northern environments: 1.1, 0.1 and 1.7 x 10{sup 4} km{sup 2} in Canada, Finland and the former Soviet Union, respectively. Interest has been generated into the role these extensive areas of peatlands play in controlling the chemistry of the atmosphere. In particular, it has become established that peatlands can be a source of methane (CH{sub 4}) and nitrous oxide (N{sub 2}O), and a sink of carbon dioxide (CO{sub 2}), the latter through the rates of plant production exceeding the rate of decomposition of plant material and peat. In this presentation the recent advances in trace gas flux measurements in northern peatlands are presented. (16 refs.)

  6. Uranium and thorium deposits of Northern Ontario

    Robertson, J.A.; Gould, K.L.

    1983-01-01

    This, the second edition of the uranium-thorium deposit inventory, describes briefly the deposits of uranium and/or thorium in northern Ontario, which for the purposes of this circular is defined as that part of Ontario lying north and west of the Grenville Front. The most significant of the deposits described are fossil placers lying at or near the base of the Middle Precambrian Huronian Supergroup. These include the producing and past-producing mines of the Elliot Lake - Agnew Lake area. Also included are the pitchblende veins spatially associated with Late Precambrian (Keweenawan) diabase dikes of the Theano Point - Montreal River area. Miscellaneous Early Precambrian pegmatite, pitchblende-coffinite-sulphide occurrences near the Middle-Early Precambrian unconformity fringing the Lake Superior basin, and disseminations in diabase, granitic rocks, alkalic complexes and breccias scattered throughout northern Ontario make up the rest of the occurrences

    The consistency of analyzed changes in surface wind stress, sea level pressures and surface temperatures between 1980-86 and previous periods indicates the reality of statistically significant and substantial climate changes in the Northern Hemisphere, especially over the North Pacific, on decadal time scales. Cooling in North Pacific sea surface temperatures and warming along the west coast of North America and Alaska are ascribed mainly to the changes in thermal advection associated with a deeper and more extensive Aleutian Low

    In this research paper efforts have been made to document the ethno-botanical knowledge of important plant species found in Northern Pakistan. It includes Thandiani, Galiat, Kaghan, Swat, Buner, Dir, Chitral and Northern Areas of Pakistan. The area has many climatic and vegetation zones or biomes. Locals residing in mountainous areas belonging to various ethnic groups are traditionally utilizing plants over many generations; these ethnic groups have their distinct life style, belief, traditions and cultural heritage. Plant collection and data regarding traditional uses in various areas of Northern Pakistan has been done periodically in different flowering /fruiting seasons. Locals of old age belonging to various ethnic groups were personally interviewed for establishing uses of plants. Photography is done for easy identification and habitat recognition. Collected plant specimens and seeds were preserved. Plant species were dried, mounted, identified and authenticated. Seventy six species were known to have traditional and ethno botanical uses. Plants have been utilized for many generations. Ethnic groups have distinct life style and have different economic uses for these plants. Due to unsustainable exploitation of natural habitats scarcity of drug plants has occurred. As consequence some species are depleting and may become extinct in near future, e. g. Morchella esculenta, Colchicum lueteum and Viola serpens are just a few of these. Although some sporadic information is available about the flora of this region but very little documented record of the ethno-botanically important plants has been established. It is expected that this research paper will be beneficial for students, researchers, farmers, foresters and general public. On the basis of data obtained it is concluded that ethno-botanical Flora of Northern Pakistan is quite rich and is diverse, due to the difference in altitude, climate and other topographic conditions.

    Irradiation is a technology which has been exploited in a wide variety of industries ranging from sterilization of medical products and polymer modification to applications with respect to food. Whilst food irradiation has recently become a controversial subject, the process has been studied for many years. Many products could be irradiated to advantage and these need to be thoroughly investigated before final recommendations can be made as to the commercial feasibility and suitability of the processing technology in the Northern Ireland context

    The ephemeral wetland system of central northern Namibia consists of the Etosha Pan, Lake Oponono and the Cuvelai inland delta/drainage. This is by far the largest wetland system in Namibia, covering some 30,000km2. The area can be subdivided into several distinct habitats, each with its distinguishing biodiversity. The Cuvelai drainage system is characterized by open, grassy drainage channels known as 'oshanas'. These are lined by the palm Hyphaene ventricosa and Colophospermum mopane tre...

    1997-08-01

    The comparison of regional patterns of recessive disease mutations is a new source of information for studies of population genetics. The analysis of phenylketonuria (PKU) mutations in Northern Ireland shows that most major episodes of immigration have left a record in the modern genepool. The mutation 165T can be traced to the Palaeolithic people of western Europe who, in the Mesolithic period, first colonised Ireland. R408W (on haplotype 1) in contrast, the most common Irish PKU mutation, may have been prevalent in the Neolithic farmers who settled in Ireland after 4500 BC. No mutation was identified that could represent European Celtic populations, supporting the view that the adoption of Celtic culture and language in Ireland did not involve major migration from the continent. Several less common mutations can be traced to the Norwegian Atlantic coast and were probably introduced into Ireland by Vikings. This indicates that PKU has not been brought to Norway from the British Isles, as was previously argued. The rarity in Northern Ireland of IVS12nt1, the most common mutation in Denmark and England, indicates that the English colonialization of Ireland did not alter the local genepool in a direction that could be described as Anglo-Saxon. Our results show that the culture and language of a population can be independent of its genetic heritage, and give some insight into the history of the peoples of Northern Ireland.

  14. Wildfires in northern Siberian larch dominated communities

    2011-01-01

    The fire history of the northern larch forests within the permafrost zone in a portion of northern Siberia (∼66°N, 100°E) was studied. Since there is little to no human activity in this area, fires within the study area were mostly caused by lightning. Fire return intervals (FRI) were estimated on the basis of burn marks on tree stems and dates of tree natality. FRI values varied from 130 to 350 yr with a 200 ± 50 yr mean. For southerly larch dominated communities, FRI was found to be shorter (77 ± 20 yr at ∼ 61°N, and 82 ± 7 at 64°N), and it was longer at the northern boundary (∼71°) of larch stands (320 ± 50 yr). During the Little Ice Age period in the 16th–18th centuries, FRI was approximately twice as long those as recorded in this study. Fire caused changes in the soil including increases in soil drainage and permafrost thawing depth, and a radial growth increase to about twice the background value (with more than six times observed in extreme cases). This effect may simulate the predicted warming impact on the larch growth in the permafrost zone.

    The fire history of the northern larch forests within the permafrost zone in a portion of northern Siberia (approx 66 deg N, 100 deg E) was studied. Since there is little to no human activities in this area fires within the study area were mostly caused by lightning. Fire return intervals (FRI) were estimated based on burn marks on tree stems and dates of tree natality. FRI values varied from 130 yr to 350 yr with 200 +/- 50 yr mean. In southerly larch dominated communities FRI was found to be shorter (77 +/- 20 yr at approx 61 deg. N, and 82 +/- 7 at 64 deg N), and longer at the northern boundary (approx 71 deg) of larch stands (320 +/- 50 yr). During the Little Ice Age period in the 16th to 18th centuries FRI was approximately twice as long as recorded in this study. Fire caused changes in the soil including increases in soil drainage and permafrost thawing depth and a radial growth increase of about 2 times (with more than 6 times observed). This effect may simulate the predicted warming impact on the larch growth in the permafrost zone.

    Full Text Available The Canadian Cryospheric Information Network and Polar Data Catalogue (CCIN/PDC provide: (1 a trusted archive to store data from Canadian cryospheric research and (2 a public access portal to this information. The CCIN/PDC has since expanded its collection to include data from health, ecological, social, and other sciences. Since its inception, CCIN/PDC has engaged Indigenous and northern Canadians to understand and meet their information needs. This paper describes three instances of such engagement and next steps for enhanced interaction and support. First, feedback from northern and Indigenous communities led to the development of PDC Lite. Compared to the full-featured online PDC Search application, PDC Lite accommodates slower Internet speeds and allows one to search by particular northern communities. PDC Lite continues to be improved by input from the people that it serves. Next, to facilitate discussion and strengthen collaborative relationships within the polar data community, CCIN/PDC co-hosted two major meetings in 2015. Emerging from both these events was a need to prioritize what has been termed 'human interoperability' and the need to have Indigenous and northern community involvement at all levels of data management. Future plans for CCIN/PDC include more effective partnerships in which we work with and listen to northern and Indigenous Canadians to better understand their requirements for data management services and expertise. Our ultimate goal is to provide, through collaboration with partners, data, information, and expertise that facilitate northern and Indigenous Canadians’ access to publicly-archived data and enable and support management of their own data and resources.

    Since 2004, the Northern Eurasia Earth Science Partnership Initiative (NEESPI) - an interdisciplinary program of internationally-supported Earth systems and science research - has addressed large-scale and long-term manifestations of climate and environmental changes over Northern Eurasia and their impact on the Global Earth system. With 40 books and more than 1500 peer-reviewed journal publications to its credit, NEESPI's output can now be used to directly support decision-making for societal needs. Specifically, it was decided to shift gradually the foci of regional studies in Northern Eurasia towards applications with the following major Science Question: "What dynamic and interactive change(s) will affect societal well-being, activities, and health, and what might be the mitigation and adaptation strategies that could support sustainable development and decision-making activities in Northern Eurasia?" To answer this question requires a stronger socio-economic component in the ongoing and future regional studies focused on sustainable societal development under changing climatic and environmental conditions. The NEESPI Research Team has reorganized itself into "Northern Eurasia Future Initiative" (NEFI) and developed a new Science Plan released in June 2016. The Plan underwent a 6-month-long public review and was finalized at the end of 2016. Its description was thereafter split between two review papers: Groisman et al. (2017) and Monier et al. (2017). The first paper describes the Plan rationale and a new set of topical questions. The second paper describes a major modeling approach that will be employed in addressing the "what to do" questions of the NEFI Research (cf., presentation by Monier et al. at this Session). In the current presentation, we outline the new NEFI research foci and present latest NEFI findings including international projects in the Eurasian Arctic, boreal zone, and the Dry Land Belt of Northern Eurasia (cf., also presentations at sister

  19. Neotectonics in the northern equatorial Brazilian margin

    An increasing volume of publications has addressed the role of tectonics in inland areas of northern Brazil during the Neogene and Quaternary, despite its location in a passive margin. Hence, northern South America plate in this time interval might have not been as passive as usually regarded. This proposal needs further support, particularly including field data. In this work, we applied an integrated approach to reveal tectonic structures in Miocene and late Quaternary strata in a coastal area of the Amazonas lowland. The investigation, undertaken in Marajó Island, mouth of the Amazonas River, consisted of shallow sub-surface geophysical data including vertical electric sounding and ground penetrating radar. These methods were combined with morphostructural analysis and sedimentological/stratigraphic data from shallow cores and a few outcrops. The results revealed two stratigraphic units, a lower one with Miocene age, and an upper one of Late Pleistocene-Holocene age. An abundance of faults and folds were recorded in the Miocene deposits and, to a minor extent, in overlying Late Pleistocene-Holocene strata. In addition to characterize these structures, we discuss their origin, considering three potential mechanisms: Andean tectonics, gravity tectonics related to sediment loading in the Amazon Fan, and rifting at the continental margin. Amongst these hypotheses, the most likely is that the faults and folds recorded in Marajó Island reflect tectonics associated with the history of continental rifting that gave rise to the South Atlantic Ocean. This study supports sediment deposition influenced by transpression and transtension associated with strike-slip divergence along the northern Equatorial Brazilian margin in the Miocene and Late Pleistocene-Holocene. This work records tectonic evidence only for the uppermost few ten of meters of this sedimentary succession. However, available geological data indicate a thickness of up to 6 km, which is remarkably thick for

  20. Accumulation of carbon in northern mire ecosystems

    The basic feature in the functional ecology of any mire ecosystem is retardation of the effective decay of organic material resulting in a conspicuous accumulation of plant debris as peat overtime. The carbon accumulation process is slow, and climatic change may have an impact on the carbon cycle of peatlands, therefore, it has been of interest to study the rate of carbon accumulation by geological methods from dated peat strata. The approach is hampered by several facts. First, the mires vary enormously as to their vegetation and hydrology and hence their production and decay properties. It follows that a great number of study sites are needed. Second, the peat in mires expands both vertically and laterally, and this requires a spatial reconstruction of carbon accumulation within a mire basin. Third, simple geological methods cannot account for the actual rate of carbon accumulation in peat, and finally, an additional carbon sink in the mire ecosystems can be the mineral subsoil beneath peat. The proposed warming will perhaps shift northwards the existing climatic mire regimes and, thus, the northern aapa fens will change to Sphagnum bogs that are more effective in sequestering carbon, but distinctly less effective in their CH{sub 4} and N{sub 2}O emanation. The role of mire fires in more remote northern areas may then become another important factor. The answer to the important question of future total sequestration of carbon to peatlands depends on the precipitation and its seasonal distribution pattern. Most climatic scenarios predict a decrease in the evaporation surplus during the summer at northern regions. Presumably, the consequent lowering of the water table would improve growth of forest on mires and simultaneously decrease the methane fluxes from peat. The combined net effect could be a clear restraining of the radiative forcing

    Northern Eurasia is a major player in the global carbon budget and includes roughly 70% of the Earth's boreal forest and more than two-thirds of the Earth's permafrost. The region has experienced dramatic climate change (increase in temperature, growing season length, floods and droughts), natural disturbances (wildfires and insect outbreaks), and land-use change (timber harvest, urbanization, expansion and abandonment of agricultural lands) over the past century. These large environmental and socioeconomic impacts have major implications for the carbon cycle in the region. Northern Eurasia is made up of a diverse set of ecosystems that range from deserts to forests, with significant areas of croplands, pastures, and urban areas. As such, it represents a complex system with substantial challenges for the modeling community. We provide an overview of past, ongoing and possible future efforts of the integrated modeling of global change for Northern Eurasia. First, we review the variety of existing modeling approaches to investigate specific components of Earth system dynamics in the region. While there are a limited number of studies that try to integrate various aspects of the Earth system through scale, teleconnections or processes, there are few systematic analyses of the various feedbacks among components within the Earth system. As a result, there is a lack of knowledge of the relative importance of such feedbacks, and it is unclear how relevant current studies, which do not account for these feedbacks, may be for policymaking. Next, we review the role of Earth system models, and their advantages/limitations compared to detailed single component models. We further introduce human activity models (e.g., global trade, economic models, demographic models), and the need for Integrated Assessment Models (IAMs), a suite of models that couple human activity models to Earth System Models. Finally, we examine emerging issues that require a representation of the coupled

  2. Evaporite karst of northern lower Michigan

    Michigan has three main zones of evaporite karst: collapse breccia in Late Silurian deposits of the Mackinac Straits region; breccia, collapse sinks, and mega-block collapse in Middle Devonian deposits of Northern Lower Michigan, which overlaps the preceding area; and areas of soil swallows in sinks of Mississippian deposits between Turner and Alabaster in Arenac and Iosco counties, and near Grand Rapids in Kent County. The author has focused his study on evaporite karst of the Middle Devonian deposits. The Middle Devonian depos its are the Detroit River Group: a series consisting of limestone, dolomite, shale, salt, gypsum, and anhydrite. The group occurs from subcrop, near the surface, to nearly 1400 feet deep from the northern tip of the Southern Peninsula to the south edge of the "solution front" Glacial drift is from zero to 350 feet thick. Oil and gas exploration has encountered some significant lost-circulation zones throughout the area. Drilling without fluid returns, casing-seal failures, and lost holes are strong risks in some parts of the region. Lost fluid returns near the top of the group in nearby areas indicate some karst development shortly after deposition. Large and irregular lost-circulation zones, linear and patch trends of large sink holes, and 0.25 mile wide blocks of down-dropped land in the northern Lower Peninsula of Michigan were caused by surface- and ground-water movement along faults into the Detroit River Group. Glaciation has removed some evidence of the karst area at the surface. Sinkhole development, collapse valleys, and swallows developed since retreat of the glacier reveal an active solution front in the Detroit River Group.

    After more than 10 years of slow developments, the offshore wind market is now accelerating. Thanks to a sustained political drive from UK and Germany, the rest of Northern Europe is now following the path as offshore wind is being recognized as one of the key resources available to the EU to meet its renewable energy ambitions. Exposed to increasing technical issues, rising costs and the financial crisis, lessons learned are now being shared and integrated throughout Europe and appropriate regulatory and planning reforms are now being deployed to speed the deployment of offshore wind.

  5. Characteristics of Swarm Seismicity in Northern California

    Science.gov (United States)

    Chiorini, S.; Lekic, V.

    2017-12-01

    Seismic swarms are characterized by an anomalously large number of earthquakes compared to the background rate of seismicity that are tightly clustered in space (typically, one to tens of kilometers) and time (typically, days to weeks). However, why and how swarms occur is poorly understood, partly because of the difficulty of identifying the range of swarm behaviors within large seismic catalogs. Previous studies have found that swarms, compared to other earthquake sequences, appear to be more common in extensional (Vidale & Shearer, 2006) and volcanic settings (Hayashi & Morita, 2003). In addition, swarms more commonly exhibit migration patterns, consistent with either fluid diffusion (Chen & Shearer, 2011; Chen et al., 2012) or aseismic creep (Lohman & McGuire, 2007), and are preferentially found in areas of enhanced heat flow (Enescu, 2009; Zaliapin & Ben Zion, 2016). While the swarm seismicity of Southern California has been studied extensively, that of Northern California has not been systematically documented and characterized. We employed two complementary methods of swarm identification: the approach of Vidale and Shearer (2006; henceforth VS2006) based on a priori threshold distances and timings of quakes, and the spatio-temporal distance metric proposed by Zaliapin et al. (2008; henceforth Z2008) in order to build a complete catalog of swarm seismicity in Northern California spanning 1984-2016 (Waldhauser & Schaff, 2008). Once filtered for aftershocks, the catalog allows us to describe the main features of swarm seismicity in Northern California, including spatial distribution, association or lack thereof with known faults and volcanic systems, and seismically quiescent regions. We then apply a robust technique to characterize the morphology of swarms, leading to subsets of swarms that are oriented either vertically or horizontally in space. When mapped, vertical swarms show a significant association with volcanic regions, and horizontal swarms with

    2009-12-01

    The Northern Eurasia Earth Science Partnership Initiative (NEESPI) was launched five years ago with the release of its Science Plan (http://neespi.org). Gradually, the Initiative was joined by numerous international projects and launched in the European Union, Russia, United States, Canada, Japan, and China. Currently, serving as an umbrella for more than 130 individual research projects (always with international participation) and with a 15M annual budget, this highly diverse initiative is in full swing. Since the first NEESPI focus issue (Pavel Groisman et al 2007 Environ. Res. Lett. 2 045008 (1pp)) in December 2007, several NEESPI Workshops and Sessions at International Meetings have been held that strengthen the NEESPI grasp on biogeochemical cycle and cryosphere studies, climatic and hydrological modeling, and regional NEESPI components in the Arctic, non- boreal Eastern Europe, Central Asia, northern Siberia, and mountainous regions of the NEESPI domain. In May 2009, an overview NEESPI paper was published in the Bulletin of the American Meteorological Society (BAMS) (Pavel Groisman et al 2009 Bull. Am. Met. Soc. 90 671). This paper also formulated a requirement to the next generation of NEESPI studies to work towards attaining a higher level of integration of observation programs, process studies, and modeling, across disciplines. Three books devoted to studies in different regions of Northern Eurasia prepared by the members of the NEESPI team have appeared and/or are scheduled to appear in 2009. This (second) ERL focus issue dedicated to climatic and environmental studies in Northern Eurasia is composed mostly from the papers that were presented at two NEESPI Open Science Sessions at the Annual Fall Meeting of the American Geophysical Union (December 2008, San Francisco, CA) and at the General Assembly of the European Geosciences Union (April 2009, Vienna, Austria), as well as at the specialty NEESPI Workshops convened in Jena, Helsinki, Odessa, Urumqi

  17. Fences and grazing management in northern Namibia

    Prudat, Brice; Bloemertz, Lena; Kuhn, Nikolaus J.

    2016-04-01

    Since Namibian independence, many fences have been erected in the communal land of the Ohangwena region in northern Namibia. Most fencing issues discussed so far in the region concern large-scale fencing of communal land by the new Namibian elite. Rarely discussed are the fences erected around small-scale farmers' parcels. This paper will discuss the impact of such increased small-scale fencing activities in northern Namibia. Fencing of land has different functions, including protection of fields against livestock and securing property rights. However, not all community members can afford the monetary and labor costs involved. In the annual agricultural cycle of the study area, livestock is left un-herded after the harvest of most crops. They can then feed on available crop remains and grass on the fields. The livestock then freely utilizes unfenced and unprotected land. This system has the advantage to accelerate crop degradation and fertilize the soils. However, by erecting efficient fences, the new middle-class community members concentrate fertility in their own field, thereby degrading agricultural soils of poorer farmers. Potentially, such small-scale fencing of land has therefore an impact on sol quality and thus fosters degradation of unfenced cropland. By using fences as features to determine the limits of the new land rights, the ongoing Communal Land Reform may not only promote the erection of fences, but may also have a negative impact on soil quality and potentially food security of small-scale farmers without cattle.

    This paper aimed at the analysis of rainfall seasonality and variability for the northern part of South-Asian country, Bangladesh. The coefficient of variability was used to determine the variability of rainfall. While rainfall seasonality index ( SI ) and mean individual seasonality index ( \\overline{SI_i} ) were used to identify seasonal contrast. We also applied Mann-Kendall trend test and sequential Mann-Kendall test to determine the trend in seasonality. The lowest variability was found for monsoon among the four seasons whereas winter has the highest variability. Observed variability has a decreasing tendency from the northwest region towards the northeast region. The mean individual seasonality index (0.815378 to 0.977228) indicates that rainfall in Bangladesh is "markedly seasonal with a long dry season." It was found that the length of the dry period is lower at the northeastern part of northern Bangladesh. Trend analysis results show no significant change in the seasonality of rainfall in this region. Regression analysis of \\overline{SI_i} and SI, and longitude and mean individual seasonality index show a significant linear correlation for this area.

    The investigation is focused on identification and origin of fossil resins from the Cretaceous, Tertiary, and Quaternary sediments of Northern Eurasia on the basis of detailed study of their physical and chemical characteristics: morphology; size; mass; density; optical, mechanical, and thermal properties; chemical composition; etc. The composition of amorphous organic minerals with polymeric structure, fossil resins included, is studied with IR spectrometry, the EPR method, derivatography at low heating rates, XRD, chemical analysis, emission spectrometry, etc. The results of investigation summarized for the Baltic-Dnieper, North Siberian, and Far East amber-bearing provinces show some similarity of fossil resins in combination with specific features inherent to each province. Resins from the Baltic-Dnieper province should be termed as amber (succinite). Their variety is the most characteristic of Northern and Eastern Europe. Amber-like fossil resins from the North Siberian and Far East provinces are irrelevant to succinite. They usually occur as brittle resins, namely, retinite and gedanite, without jewelry value. Viscous fossil resin rumänite with an expected high economic value occurs in the Far East, on the shore of Sakhalin Island.

    1998-06-01

    This report is about the market for airline travel in northern New Mexico. Interest in developing a northern New Mexico regional airport has periodically surfaced for a number of years. The New Mexico State Legislature passed a memorial during the 1998 Second Session calling for the conduct of a study to determine the feasibility of building a new regional airport in NNM. This report is a study of the passenger market feasibility of such an airport. In addition to commercial passenger market feasibility, there are other feasibility issues dealing with siting, environmental impact, noise, economic impact, intermodal transportation integration, region-wide transportation services, airport engineering requirements, and others. These other feasibility issues are not analyzed in any depth in this report although none were discovered to be show-stoppers as a by-product of the authors doing research on the passenger market itself. Preceding the need for a detailed study of these other issues is the determination of the basic market need for an airport with regular commercial airline service in the first place. This report is restricted to an in-depth look at the market for commercial passenger air service in NNM. 20 figs., 8 tabs.

    This paper provides significant ethnobotanical information on pharmaceutical plant uses in Northern Navarra from an area known both for its high biological diversity and its cultural significance, suggesting the survival of uses lost elsewhere. Collect, analyze and evaluate the ethnobotanical knowledge about medicinal plants in Northern Navarra (Iberian Peninsula) with 4243 km(2) and 71,069 inhabitants. We performed semi-structured interviews with 253 informants (mean age 69; 61% women, 39% men) in 120 locations, identified the plant reported and analyzed the results, comparing them with those from other territories. The informants reported data on 174 medicinal plants belonging to 63 botanical families. This work is focused on human medicinal plant uses, which represent 98% of the pharmaceutical uses (1725 use reports). The species with the highest number of cites are Chamaemelum nobile, Sambucus nigra and Verbena officinalis, with a long tradition of use in The Mountain (Navarra). All different plant parts are used; aerial part is exploited more frequently than other plant parts. Most of the listed remedies use a single ingredient, typically soaked in water. Usually, the administration is primarily oral followed by topical applications. The main ailments treated are digestive troubles, wounds and dermatological problems, and respiratory affections. Informants reported 24 new or scarcely cited uses for 23 medicinal plants. For 35% of the species (8) we have not found bibliographical references in the scientific literature and 48% (11) have only one to three references. Copyright © 2010 Elsevier Ireland Ltd.

  2. Floods in Canada and Northern Minnesota

    Science.gov (United States)

    2002-01-01

    During the first half of June, heavy rains inundated northern Minnesota and southern Canada, giving rise to floods that drove hundreds of people from their homes and drenched more than 300,000 acres of prime farmland. This false-color image of the flood (right) was acquired on June 15, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. The worst of the flooding occurred on the border of Canada and Minnesota along the Roseau River, which now resembles a lake in the center of the image. The town of Roseau, Minnesota, which sits in the eastern end of the newly formed lake, was hit the hardest. Nearly all the buildings in the town took heavy water damage and many residents were forced to leave. Widespread flooding across an eight county region in Minnesota has drenched nearly 300,000 to 500,000 acres of farmland altogether. Many of the farmers hit lost 100 percent of their crops and will be unable to plant again for the season. Last week, President Bush declared northern Minnesota a disaster area. Normally, the Roseau River cannot even be seen on a MODIS image (left, acquired May 21, 2002), and the surrounding area is dry. In the false-color images, sage green, rusty orange, and blue is land, and water is black. Clouds are white and pink. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC

  3. Trophic ecology of largemouth bass and northern pike in allopatric and sympatric assemblages in northern boreal lakes

    2000-01-01

    Largemouth bass (Micropterus salmoides) and northern pike (Esox lucius) are top predators in the food chain in most aquatic environments that they occupy; however, limited information exists on species interactions in the northern reaches of largemouth bass distribution. We investigated the seasonal food habits of allopatric and sympatric assemblages of largemouth bass and northern pike in six interior lakes within Voyageurs National Park, Minnesota. Percentages of empty stomachs were variable for largemouth bass (38-54%) and northern pike (34.7-66.7%). Fishes (mainly yellow perch, Perca flavescens) comprised greater than 60% (mean percent mass, MPM) of the northern pike diet during all seasons in both allopatric and sympatric assemblages. Aquatic insects (primarily Odonata and Hemiptera) were important in the diets of largemouth bass in all communities (0.0-79.7 MPM). Although largemouth bass were observed in the diet of northern pike, largemouth bass apparently did not prey on northern pike. Seasonal differences were observed in the proportion of aquatic insects (P = 0.010) and fishes (P = 0.023) in the diets of northern pike and largemouth bass. Based on three food categories, jackknifed classifications correctly classified 77 and 92% of northern pike and largemouth bass values, respectively. Percent resource overlap values were biologically significant (greater than 60%) during at least one season in each sympatric assemblage, suggesting some diet overlap.

  4. The Lemmatization of Copulatives in Northern Sotho *

    Abstract: For learners of Northern Sotho as a second or even foreign language, the copulative system is probably the most complicated grammatical system to master. The encoding needs of such learners, i.e. to find enough information in dictionaries in order to actively use copulatives in speech and writing, are poorly served in currently available dictionaries. The aim of this article is to offer solutions to the lemmatization problems regarding copulatives in Northern Sotho and to propose guiding entries for paper and electronic dictionaries which could serve as models for future dictionaries. It will be illustrated that the maximum utilisation of macrostructural and microstructural strategies as well as the mediostructure is called for in order to reach this objective. Prerequisites will be to reconstruct the entire copulative system in a user-friendly way, to abstract the rules governing the use of copulatives and to isolate the appropriate lemmas. The treatment of copulatives in Northern Sotho dictionaries will also be critically evaluated, especially in terms of frequency of use and target users' needs.

  5. Cenozoic stratigraphy of the Sahara, Northern Africa

    Science.gov (United States)

    Swezey, Christopher S.

    2009-01-01

    This paper presents an overview of the Cenozoic stratigraphic record in the Sahara, and shows that the strata display some remarkably similar characteristics across much of the region. In fact, some lithologies of certain ages are exceptionally widespread and persistent, and many of the changes from one lithology to another appear to have been relatively synchronous across the Sahara. The general stratigraphic succession is that of a transition from early Cenozoic carbonate strata to late Cenozoic siliciclastic strata. This transition in lithology coincides with a long-term eustatic fall in sea level since the middle Cretaceous and with a global climate transition from a Late Cretaceous–Early Eocene “warm mode” to a Late Eocene–Quaternary “cool mode”. Much of the shorter-term stratigraphic variability in the Sahara (and even the regional unconformities) also can be correlated with specific changes in sea level, climate, and tectonic activity during the Cenozoic. Specifically, Paleocene and Eocene carbonate strata and phosphate are suggestive of a warm and humid climate, whereas latest Eocene evaporitic strata (and an end-Eocene regional unconformity) are correlated with a eustatic fall in sea level, the build-up of ice in Antarctica, and the appearance of relatively arid climates in the Sahara. The absence of Oligocene strata throughout much of the Sahara is attributed to the effects of generally low eustatic sea level during the Oligocene and tectonic uplift in certain areas during the Late Eocene and Oligocene. Miocene sandstone and conglomerate are attributed to the effects of continued tectonic uplift around the Sahara, generally low eustatic sea level, and enough rainfall to support the development of extensive fluvial systems. Middle–Upper Miocene carbonate strata accumulated in northern Libya in response to a eustatic rise in sea level, whereas Upper Miocene mudstone accumulated along the south side of the Atlas Mountains because uplift of the

    We identify eleven megafans (partial cones of fluvial sediment, >80 km radius) in the northern Kalahari Basin, using several criteria based on VIS and IR remotely sensed data and SRTM-based surface morphology reconstructions. Two other features meet fewer criteria of the form which we class as possible megafans. The northern Kalahari megafans are located in a 1700 km arc around the southern and eastern flanks of the Angola's Bié Plateau, from northern Namibia through northwest Botswana to western Zambia. Three lie in the Owambo subbasin centered on the Etosha Pan, three in the relatively small Okavango rift depression, and five in the Upper Zambezi basin. The population includes the well-known Okavango megafan (150 km), Namibia's Cubango megafan, the largest megafan in the region (350 km long), and the largest nested group (the five major contiguous megafans on the west slopes of the upper Zambezi Valley). We use new, SRTM-based topographic roughness data to discriminate various depositional surfaces within the flat N. Kalahari landscapes. We introduce the concepts of divide megafans, derived megafans, and fan-margin rivers. Conclusions. (i) Eleven megafan cones total an area of 190,000 sq km. (ii) Different controls on megafan size operate in the three component basins: in the Okavango rift structural controls become the prime constraint on megafan length by controlling basin dimensions. Megafans in the other les constricted basins appear to conform to classic relationships fan area, slope, and feeder-basin area. (iii) Active fans occupy the Okavango rift depression with one in the Owambo basin. The rest of the population are relict but recently active fans (surfaces are relict with respect to activity by the feeder river). (iv) Avulsive behavior of the formative river-axiomatic for the evolution of megafans-has resulted in repeated rearrangements of regional drainage, with likely effects in the study area well back into the Neogene. Divide megafans comprise the

    In this article, we examine perceptions about the definition of physical intimate partner violence (IPV) in northern India utilizing feminist perspectives as a framework. We interviewed 56 women and 52 men affiliated with a health services nongovernmental organization in the Udaipur district of Rajasthan. We transcribed, coded, and analyzed the interviews utilizing grounded theory. We found that perceptions regarding physical IPV were associated with both structural and ideological patriarchal beliefs and microlevel constructs such as alcohol use. We discovered multiple types of physical IPV in the study region, including rationalized violence (socially condoned violence perpetrated by a husband against his wife), unjustified violence (socially prohibited violence perpetrated by a husband against his wife), and majboori violence (violence perpetrated by a wife against her husband). Our results add to the breadth of research available about IPV in India and create a framework for future research and IPV prevention initiatives.

  12. Distributed generation in small remote Northern communities

    International Nuclear Information System (INIS)

    Malcolm, D.G.

    2012-01-01

    The presentation discusses the physical and social challenges of reliable and environmentally sound electricity generation in remote northern communities in Canada. There are several hundred remote communities in the boreal region of Canada and throughout the Arctic. Electrical energy requirements are usually a few megawatts. Access to some Arctic remote communities is by air and small water craft only, except when winters are cold enough for winter roads to be constructed for a few weeks each year. These communities, as well as new mining operations and their camp communities, provide a market segment for small reactors. However, there are social acceptance hurdles to be addressed. Trust-building is a must when working with First Nations, Metis, and Inuit communities, and this requires community presence long before proposals for new generation facilities are presented.

    Total particulate mercury (TPM) in air has been measured during five 2-week campaigns at five measurement sites in Northern Europe. The measurements covered four seasons and the result constitutes a unique TPM data set from this region. Evidence for transport of TPM on a regional scale is reported as well as the historical trend of TPM in south of Sweden. All TPM measurements were made using a new mini particulate sampler. The device consists of a quartz fibre filter contained in a quarts glass filter holder and is a modified version of the MiniSamplr. This approach proves to be reliable and more cost efficient in comparison to alternative methods. Tests made to evaluate the performance of the sampler in terms of precision and comparability with sampling on Teflon membrane filters are also reported.

    Earth's climate underwent a major transition from the warmth of the late Pliocene, when global surface temperatures were ~2° to 3°C higher than today, to extensive Northern Hemisphere glaciation (NHG) ~2.73 million years ago (Ma). We show that North Pacific deep waters were substantially colder (4°C) and probably fresher than the North Atlantic Deep Water before the intensification of NHG. At ~2.73 Ma, the Atlantic-Pacific temperature gradient was reduced to <1°C, suggesting the initiation of stronger heat transfer from the North Atlantic to the deep Pacific. We posit that increased glaciation of Antarctica, deduced from the 21 ± 10-meter sea-level fall from 3.15 to 2.75 Ma, and the development of a strong polar halocline fundamentally altered deep ocean circulation, which enhanced interhemispheric heat and salt transport, thereby contributing to NHG.

    Many arboreal primates descend to the ground, a custom that may occur more frequently in disturbed habitats, and in the presence of researchers to whom the primates are habituated. In this paper, we describe opportunistic observations of ground use in two groups of northern muriquis (Brachyteles hypoxanthus) at the RPPN Feliciano Miguel Abdala, Minas Gerais, Brazil. Members of both groups were observed drinking, resting, feeding, playing, and traveling on the ground to different degrees, and variation in the levels of habituation of the two groups may be responsible for the differences in the distribution of their terrestrial activities. The potential increase in vulnerability to predation or disease owing to ground use has implications for the conservation of this critically endangered species. (c) 2007 Wiley-Liss, Inc.

  16. Coping with Rainfall Variability in Northern Tanzania

    2012-01-01

    This paper explores a potential relationship between rainfall data and household self-reported harvest shocks and local (spatial) variability of harvest shocks and coping strategies based on a survey of 2700 rural households in the Kagera region of northern Tanzania. In addition, correlations...... of household reported harvest shocks differs significantly between districts and correspond to the observed variability in local climate patterns. Coping strategies are focused on spreading risks and include reduced consumption, casual employment, new crops, external support and the selling of assets....... There are no large differences in applied coping strategies across the region, but district-level data demonstrate how local strategies differ between localities within the districts. The results emphasize that in order to target rural policies and make them efficient, it is important to take into account the local...

    2001-04-01

    The experience of the Northern region using the 1995 draft National Gynaecological Cervical Cytology External Quality Assurance (EQA) Scheme is given. Over three rounds, 390 staff reporting Cervical Cytology took part, and using a cumulative non-numeric marking scheme, five participants were deemed "unacceptable" at the end of three rounds. A total of 3450 responses were given to the 40 test slides used, with an overall false-positive rate of 5.9% and a false-negative rate of 1.4%. Grading was assessed for pathologists, and many appeared to perform badly by accumulating discrepancies for non-clinically-significant grading differences. The problems of slide selection/staining and grading consistency/accuracy are highlighted. This EQA scheme serves its dual function of education and identifying poor performance. It must be seen as a viable EQA scheme, although other options must be considered, given advances in technology.

    . The hypothesis is that places can appear not only as places in their own right, but also as locations in media contexts at the same time. They may have been used in films and TV series, so that they have become known in this way. E.g., the Odessa Steps from Sergei Eisenstein's Battleship Potemkin (1925) or Mount...... Rushmore's presidential sculptures from Hitchcock's North by Northwest (1959). More generally, places may also appear as stereotypical location topoi. E.g., underground car parks are recognized from innumerable crime films and thrillers as a dramaturgically perilous location, and not just as an Augé......-non-place. They are not just places to park. In the same sense, already in 1981 in his treatment of hyperreality Baudrillard claimed that America in itself was a sign, as America could only be recognized from media and films and not cognized in itself. The article will view Northern Jutland in this light, and places...

    Niskanen, Tuula; Kytövuori, Ilkka; Liimatainen, Kare

    2011-01-01

    Cortinarius sect. Armillati (subgenus Telamonia) was studied extensively based on morphology and molecular data. A total of about 1000 specimens, mostly from Fennoscandia, were revised. The nomenclature of the species was confirmed by sequencing the type material. Phylogenetic relationships were inferred by analyses of ITS, and the results were compared with the morphological and ecological data. Based on macro- and micromorphological characters, as well as molecular data, section Armillati contains only the medium to large species with slightly hygrophanous pileus and ± reddish or in some species yellowish brown to rose brown universal veils. The other red-brown-veiled species, previously included in Armillati, seem to belong to at least seven different sections or clades: sect. Anthracini, sect. Boulderenses, sect. Brunneotincti p.p., sect. Cinnabarini, sect. Fulvescentes, /Fuscoperonatus, and /Praestigiosus. Our study recognized six Armillati species from northern Europe: C. armillatus, C. luteo-ornatus, C. paragaudis, and three species described as new, C. pinigaudis, C. roseoarmillatus, and C. suboenochelis. The former three also occur in North America. Two additional species, C. subarmillatus (Japan) and C. quercoarmillatus (Costa Rica), are known outside the area. Based on the phylogenetic analysis, the species associated with deciduous trees, C. armillatus, C. quercoarmillatus, and C. roseoarmillatus, all with dextrinoid, thick-walled spores, formed a separate group from the mainly conifer-associated species, C. luteo-ornatus, C. paragaudis, C. pinigaudis and C. suboenochelis, all with fairly thin to moderately thick-walled, indextrinoid to moderately dextrinoid spores. Descriptions of the northern European species are provided, the distribution is mapped and their taxonomy, ecology, distribution, and relationships are discussed. A total of 64 new sequences of 12 species are reported including 17 sequences from type material. Our study also suggests that

  2. Northern peatlands in global climatic change

    Northern peatlands are important in regulating the global climate. While sequestering carbon dioxide, these peatlands release ca. 24-39 Tg methane annually to the atmosphere. This is 5-20 % of the annual anthropogenic methane emissions to the atmosphere. The greenhouse gas balance of peatlands may change as a consequence of water level draw-down after land-use change, or if summers become warmer and drier, as has been predicted for high latitudes after climatic warming. Subsequent emissions of methane would decrease, whereas emissions of carbon dioxide and nitrous oxide would increase. Within the Finnish Research Programme on Climate Change (SILMU), the research project `Carbon Balance of Peatlands and Climate Change` (SUOSILMU) has been under progress since 1990. It is a co-operative research project, with research groups from the Universities of Helsinki and Joensuu, the Finnish Forest Research Institute, the National Public Health Institute and the Finnish Environment Agency. The research consortium of this project organised a workshop entitled `Northern Peatlands in Global Climatic Change - Hyytiaelae Revisited` October 8-12, 1995. The main objective of the workshop was to review the state of the art of the carbon cycling research in natural and managed peatlands. The role of peatlands in the greenhouse effect, their response and feedback to the predicted climate change, and the consequences of land-use changes were assessed, and the future research needs were evaluated. The latest information on the role of peatlands in the atmospheric change was given in 50 posters and 4 key lectures. Results of SUOSILMU projects were demonstrated during a 1-day field excursion to one of the intensive study sites, Lakkasuo near Hyytiaelae

    People of northern Pakistan face health hazards because of poor sanitation practices. Bacterial gastrointestinal infections are very common, and sometimes outbreaks occur. The present study was aimed at evaluating and analyzing infestation of Shigella spp. in patients with suspected gastroenteritis and ascertaining the status of antibiotic therapy. Five hundred and eighty-five faecal samples of patients with suspected gastroenteritis, referred to the District Headquarter Hospital Gilgit, were investigated for common enteropathogenic bacteria from July 1997 to September 1999. Seventy-seven (13.2%) of the faecal specimens were infected with different strains of Shigella spp., 61% of which were Shigella dysenteriae, 15.6% were S. flexneri, and 23.4% were Shigella sp. All Shigella strains were sensitive to ceftriaxone, cefotaxime, ciprofloxacin, and enoxacin. Sixty-one percent of the strains were resistant to both ampicillin and chloramphenicol, and 3.9% to ampicillin and nalidixic acid, while 10.4% were resistant to ampicillin alone and 14.3% to chloramphenicol only. Only 10.4% of the strains were sensitive to all the antibiotics tested. Sixty strains of Shigella spp. were processed for isolation of plasmids, and 58 (97%) of these antibiotic-resistant bacteria harboured at least one plasmid. The number of plasmids varied from 1 to 9. Escherichia coli C600 were transformed with the isolated plasmids. Transformants, containing 23-kb plasmid, resisted growth in media containing antibiotics, thereby indicating that antibiotic resistance is plasmid-borne. Based on the findings of the study, it is concluded that the infestation of Shigella spp. is high in northern Pakistan, the aetiological agents are highly resistant to chloramphenicol and ampicillin, and the antibiotic resistance is mediated by the 23-kb plasmid.

  4. Imaging Lithospheric-scale Structure Beneath Northern Altiplano in Southern Peru and Northern Bolivia

    The northern Altiplano plateau of southern Peru and northern Bolivia is one of the highest topographic features on the Earth, flanked by Western and Eastern Cordillera along its margin. It has strongly influenced the local and far field lithospheric deformation since the early Miocene (Masek et al., 1994). Previous studies have emphasized the importance of both the crust and upper mantle in the evolution of Altiplano plateau (McQuarrie et al., 2005). Early tomographic and receiver function studies, south of 16° S, show significant variations in the crust and upper mantle properties in both perpendicular and along strike direction of the Altiplano plateau (Dorbath et. al., 1993; Myers et al., 1998; Beck and Zandt, 2002). In order to investigate the nature of subsurface lithospheric structure below the northern Altiplano, between 15-18° S, we have determined three-dimensional seismic tomography models for Vp and Vs using P and S-wave travel time data from two recently deployed local seismic networks of CAUGHT and PULSE. We also used data from 8 stations from the PERUSE network (PERU Subduction Experiment). Our preliminary tomographic models show a complex variation in the upper mantle velocity structure with depth, northwest and southeast of lake Titicaca. We see the following trend, at ~85 km depth, northwest of lake Titicaca: low Vp and Vs beneath the Western Cordillera, high Vs beneath the Altiplano and low Vp and Vs beneath the Eastern Cordillera. This low velocity anomaly, beneath Eastern Cordillera, seems to coincide with Kimsachata, a Holocene volcano in southern Peru. At depth greater than ~85 km: we find high velocity anomaly beneath the Western Cordillera and low Vs beneath the Altiplano. This high velocity anomaly, beneath Western Cordillera, coincides with the well-located Wadati-Benioff zone seismicity and perhaps represents the subducting Nazca slab. On the southeast of lake Titicaca, in northern Bolivia, we see a consistently high velocity anomaly

  5. Background document for climate change policy options in Northern Canada

    Newton, J.

    2001-01-01

    This paper presents an initial compilation of background material in support of the development of climate change policy options for the jurisdictions of Yukon, Northwest Territories and Nunavut in Northern Canada. While Northern Canada contributes only a small fraction of the world's greenhouse gas (GHG) emissions, scientists forecast changes in average annual temperatures to be among the highest in the world. The Northern Climate Exchange at Yukon College was created in March 2001 to address this issue and to help guide northerners in what they can do now and in the future. This paper includes an annotated bibliography of a total of 75 international, national, and territorial policy documents and major reference documents relevant to climate change issues. It is meant to be a resource for researchers, policy analysts and government officials developing policy options and implementing programs for Northern Canada. While each of the three northern territories are at a different stage in the evolution of their climate change activities, they are all striving to develop strategies and action plans and to initiate the implementation of those plans. It is recognized that many long-standing programs and initiatives, particularly in the areas of energy efficiency and alternate energy, will help northern jurisdictions address their climate change objectives. The three territories are cooperating to deliver their message to the federal government. 75 refs., 4 figs

  6. Hypoxia in the Northern Gulf of Mexico

    Energy Technology Data Exchange (ETDEWEB)

    Dale, Virginia H [ORNL

    2010-01-01

    Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot support marine life, generally manifests itself in the spring. Since marine species either die or flee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational fishing in the Gulf. Since 2001, the hypoxic zone has averaged 16,500 km{sup 2} during its peak summer months, an area slightly larger than the state of Connecticut, and ranged from a low of 8,500 km{sup 2} to a high of 22,000 km{sup 2}. To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (or Task Force) was formed to bring together representatives from federal agencies, states, and tribes to consider options for responding to hypoxia. The Task Force asked the White House Office of Science and Technology Policy to conduct a scientific assessment of the causes and consequences of Gulf hypoxia through its Committee on Environment and Natural Resources (CENR). In 2000 the CENR completed An Integrated Assessment: Hypoxia in the Northern Gulf of Mexico (or Integrated Assessment), which formed the scientific basis for the Task Force's Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico (Action Plan, 2001). In its Action Plan, the Task Force pledged to implement ten management actions and to assess progress every 5 years. This reassessment would address the nutrient load reductions achieved, the responses of the hypoxic zone and associated water quality and habitat conditions, and economic and social effects. The Task Force began its reassessment in 2005. In 2006 as part of the reassessment, USEPA's Office of Water, on behalf of the Task Force, requested that the U.S. Environmental Protection Agency (USEPA) Science Advisory Board (SAB) convene an independent

    During the Campanian-Maastrichtian, Patagonia was flooded by the Atlantic and reduced to an archipelago. Several localities of northern Patagonia have yielded marine reptiles. Analysis of several assemblages suggests that the diversity and abundance of pelagic marine reptiles in northern Patagonia was higher by the end of the Cretaceous than previously thought. Several plesiosaurids, including Aristonectes parvidens and the polycotylid Sulcusuchus, and the first remains of mosasaurinae have been found. The Cretaceous marine reptile record from South America is scanty. Nevertheless, materials described here suggest that Tethyan and Weddelian forms converged in northern Patagonia, as seen with invertebrates.

    1993-01-01

    Measurements of radon made in some 1500 dwellings throughout Northern Ireland by the autumn of 1993 show that the average concentration is 19 Bq m -3 with some values up to fifty times higher. Around 30 of these dwellings are above the Action Level of 200 Bq m -3 adopted by the Government. Data are presented in considerable detail and various forms. Several hundred dwellings in Northern Ireland are estimated to exceed the Action Level, most of which are in a separately designated Affected Area in the southeast. Recommendations are made to promote the discovery and remedy of dwellings above the Action Level throughout Northern Ireland. (author)

  9. Primary immunodeficiency diseases in Northern Iran.

    Mohammadzadeh, I; Moazzami, B; Ghaffari, J; Aghamohammadi, A; Rezaei, N

    Primary immunodeficiency diseases (PID) are a heterogeneous group of inherited disorders, characterised by recurrent severe infections, autoimmunity and lymphoproliferation. Despite impressive progress in identification of novel PID, there is an unfortunate lack of awareness among physicians in identification of patients with PID, especially in non-capital cities of countries worldwide. This study was performed in a single-centre paediatric hospital in Northern Iran during a 21-year period (1994-2015). Ninety-four patients were included in this study. The majority of cases had antibody deficiencies (37.23%), followed by well-defined syndromes with immunodeficiency in 16 (17.02%), phagocytic disorders in 15 patients (15.95%), complement deficiencies in 15 patients (15.95%), immunodeficiencies affecting cellular and humoral immunity in nine patients (9.57%), disease of immune dysregulation in three (3.19%), and defects in intrinsic and innate immunity in one (1.06%). It seems that there are major variations in frequency of different types of PID in different regions of a country. Therefore, reporting local data could provide better ideas to improve the local health care system strategists and quality of care of PID patients. Copyright © 2017 SEICAP.

    Haematophagous mites were collected from the vent region and plumage of chickens in six hobby flocks of ornamental breeds in Sweden, one of which included turkeys. Soiled vent skin and feathers, dermatitis, hyperkeratosis, skin necroses and ulcers were observed in 12 necropsied birds from two of the flocks. The mites were identified as the northern fowl mite Ornithonyssus sylviarum (Mesostigmata: Macronyssidae). This was supported by sequence analysis of a 642-bp region in the mitochondrial cytochrome oxidase subunit 1 (COI) gene (COI) in mites collected from five flocks, which showed 97-99% sequence similarity to O. sylviarum by blast analysis. Pairwise sequence comparisons revealed nucleotide variations in the range of 0-2.8%, whereas amino acid sequences were highly conserved. This paper represents one of very few records of O. sylviarum in European poultry, and is the first to report COI sequence data for O. sylviarum from poultry in Europe. © 2014 The Royal Entomological Society.

    Recent reports of reductions in malaria transmission in several African countries have resulted in optimism that malaria can be eliminated in parts of Africa where it is currently endemic. It is not known whether these trends are global or whether they are also present in areas where political instability has hindered effective malaria control. We determined malaria parasite carriage and age-dependent antibody responses to Plasmodium falciparum antigens in cross-sectional surveys in Apac, northern Uganda that was affected by political unrest. Under-five parasite prevalence was 55.8% (115/206) by microscopy and 71.9% (41/57) by polymerase chain reaction. Plasmodium ovale alone, or as a co-infection, was detected in 8.6% (12/139) and Plasmodium malariae in 4.3% (6/139) of the infections. Age seroprevalence curves gave no indication of recent changes in malaria transmission intensity. Malaria control remains a tremendous challenge in areas that have not benefited from large-scale interventions, illustrated here by the district of Apac. PMID:21540398

  12. Environmental factors along the Northern Sea Route

    1993-01-01

    The Northern Sea Route runs ca 5,600 nautical miles across the top of Russia from Murmansk to Vladivostok, and includes half of the Arctic basin. An environmental impact assessment is needed for this route because of the potential for commercial shipping to disturb the vulnerable Arctic environment along the route. For example, Russian development of oil and gas resources in the area served by the route is expected to rise dramatically in the near future. Drilling in the route area offshore has already begun, and potential blowouts or tanker spills are of concern. A pilot study on the environment along this route was conducted in 1990/91, focusing on a study of the literature and communications with Russian scientists working on Arctic ecology. Existing data seem to be insufficient and generally only cover the westernmost and easternmost parts of the route. A five-year research plan is proposed to provide an inventory of Arctic species in the route area and levels of contaminants present, to assess the environmental sensitivity of the area, and analyze impacts that increased shipping might have on the environment. Protection measures will also be suggested. 1 fig

    2004-01-01

    In 2003, the Cameroon Ministry of the Environment and Forestry has initiated a research project for studying the promotion of renewable energies and their impact on rural development. This work has been realized jointly with the department of Economy and Rural Development of the Agronomic University of Gembloux (Belgium), the Centre Des Etudes de L'Environnement et de Developpement du Cameroun (CEDC, Maroua) and the Institut fur Solare Energieversorgungstechnik (ISET, Germany). This initiative comes when the electricity sector in Cameroon has been facing important changes (Privatization of the national company of electricity, creation of a rural electrification agency, multiplication of the dialogues and seminars around the strategies of promotion for renewable energies, frequent black-outs during the dry season). The first objective of the project is to contribute to a better knowledge of the situation of the use of renewable energies in Cameroon. Therefore, Mrs Marthe Djuikom undertook from July to September 2003 a socio-economic survey on the use of solar energy in the northern Cameroon. The next step will be the creation of an energy program at the CEDC with the following tasks: promotion of photovoltaic technology, support of local and international synergies on the organisational aspects, training, information and coordination of reflexions at the local level for the promotion of rural electrification projects.

  14. Virtual Northern analysis of the human genome.

    Evan H Hurowitz

    2007-05-01

    Full Text Available We applied the Virtual Northern technique to human brain mRNA to systematically measure human mRNA transcript lengths on a genome-wide scale.We used separation by gel electrophoresis followed by hybridization to cDNA microarrays to measure 8,774 mRNA transcript lengths representing at least 6,238 genes at high (>90% confidence. By comparing these transcript lengths to the Refseq and H-Invitational full-length cDNA databases, we found that nearly half of our measurements appeared to represent novel transcript variants. Comparison of length measurements determined by hybridization to different cDNAs derived from the same gene identified clones that potentially correspond to alternative transcript variants. We observed a close linear relationship between ORF and mRNA lengths in human mRNAs, identical in form to the relationship we had previously identified in yeast. Some functional classes of protein are encoded by mRNAs whose untranslated regions (UTRs tend to be longer or shorter than average; these functional classes were similar in both human and yeast.Human transcript diversity is extensive and largely unannotated. Our length dataset can be used as a new criterion for judging the completeness of cDNAs and annotating mRNA sequences. Similar relationships between the lengths of the UTRs in human and yeast mRNAs and the functions of the proteins they encode suggest that UTR sequences serve an important regulatory role among eukaryotes.

    The Key Lake Operation is committed to a policy of maximizing Saskatchewan, and particularly northern Saskatchewan, employment and business opportunities. The participation rate of northern people in the Key Lake operation's workforce has risen from 23.8% in 1983, to 42% today. Cameco's objective is to achieve 50% representation of residents of Saskatchewan's north in the Key Lake workforce by 1995. The company also extends this strategic objective to contractors. All contractors are required to maximize employment opportunities for residents of Saskatchewan's north, and report employment levels to the company as a condition of the contract. Today, contractors at the Key Lake site have achieved a northern participation rate of 47%. This paper highlights strategies for increasing northern/aboriginal participation and provides several examples of successes from these initiatives. (author)

    2013-08-01

    Full Text Available Background . Canada's North is a diverse, sparsely populated land, where inequalities and public health issues are evident, particularly for Aboriginal people. The Northern public health workforce is a unique mix of professional and paraprofessional workers. Few have formal public health education. From 2009 to 2012, the Public Health Agency of Canada (PHAC collaborated with a Northern Advisory Group to develop and implement a strategy to strengthen public health capacity in Canada's 3 northern territories. Access to relevant, effective continuing education was identified as a key issue. Challenges include diverse educational and cultural backgrounds of public health workers, geographical isolation and variable technological infrastructure across the north. Methods . PHAC's Skills Online program offers Internet-based continuing education modules for public health professionals. In partnership with the Northern Advisory Group, PHAC conducted 3 pilots between 2008 and 2012 to assess the appropriateness of the Skills Online program for Northern/Aboriginal public health workers. Module content and delivery modalities were adapted for the pilots. Adaptations included adding Inuit and Northern public health examples and using video and teleconference discussions to augment the online self-study component. Results . Findings from the pilots were informative and similar to those from previous Skills Online pilots with learners in developing countries. Online learning is effective in bridging the geographical barriers in remote locations. Incorporating content on Northern and Aboriginal health issues facilitates engagement in learning. Employer support facilitates the recruitment and retention of learners in an online program. Facilitator assets included experience as a public health professional from the north, and flexibility to use modified approaches to support and measure knowledge acquisition and application, especially for First Nations, Inuit and

    1984-01-01

    Feeding trials were used to compare the ability of northern pintails (Anas acuta), gadwalls (A. strepera), and northern shovelers (A. clypeata) to metabolize energy from a turkey starter ration, alfalfa pellets, and common barnyardgrass (Echinochloa crusgalli) seeds. No differences (P > 0.05) were detected among the three species for any of the three foods (kg body weight/day basis), for dry matter intake (DMI), body weight gain (BWG), apparent metabolizable energy (AME), or metabolized energy (MEE) on any given diet consumed in quantities large enough to promote body weight gain. The AME content of alfalfa was 57% less than the value for turkey starter and 50% less than for barnyardgrass seeds. All three species metabolized more energy and gained weight faster when fed turkey starter. Energy modeling may be facilitated if additional research verifies that all species of dabbling ducks have equal ability to obtain energy from foods available to them in the wild. Behavioral and morphological factors may be more important in defining feeding niches than digestive physiology, at least for the three duck species tested, at the time of year of the experiments, and within the limits of the quality of foods used.

    The RISNA project, financed by the Emergency Agency of Navarre (Northern Spain), aims at assessing the seismic risk of the entire region. The final goal of the project is the definition of emergency plans for future earthquakes. With this purpose, four main topics are covered: seismic hazard characterization, geotechnical classification, vulnerability assessment and damage estimation to structures and exposed population. A geographic information system is used to integrate, analyze and represent all information colleted in the different phases of the study. Expected ground motions on rock conditions with a 90% probability of non-exceedance in an exposure time of 50 years are determined following a Probabilistic Seismic Hazard Assessment (PSHA) methodology that includes a logic tree with different ground motion and source zoning models. As the region under study is located in the boundary between Spain and France, an effort is required to collect and homogenise seismological data from different national and regional agencies. A new homogenised seismic catalogue, merging data from Spanish, French, Catalonian and international agencies and establishing correlations between different magnitude scales, is developed. In addition, a new seismic zoning model focused on the study area is proposed. Results show that the highest ground motions on rock conditions are expected in the northeastern part of the region, decreasing southwards. Seismic hazard can be expressed as low-to-moderate. A geotechnical classification of the entire region is developed based on surface geology, available borehole data and morphotectonic constraints. Frequency-dependent amplification factors, consistent with code values, are proposed. The northern and southern parts of the region are characterized by stiff and soft soils respectively, being the softest soils located along river valleys. Seismic hazard maps including soil effects are obtained by applying these factors to the seismic hazard maps

  8. Gas seepage in the Northern Adriatic Sea

    In the Northern Adriatic Sea, the occurrence of gas seepage has been widely documented. However, the origin of seeping gas was not clearly constrained. Geophysical data with different scale of resolution, i.e. multichannel seismic profiles, CHIRP and morpho-bathymetry data collected in 2009 and 2014 by OGS reveal that several the gas-enriched fluid vents are deeply rooted. In fact, the entire Plio-Quaternary succession is characterized by widespread seismic anomalies represented by wipe-out zones and interpreted as gas chimneys. They commonly root at the base of the Pliocene sequence but also within the Paleogene succession, where they appear to be associated to deep-seated, Mesozoic-to-Paleogene faults. These chimneys originate and terminate at different stratigraphic levels; they also commonly reach the seafloor, where rock outcrops interpreted as authigenic carbonate deposits have been recognized. In places, gas is then capable to escape in the water column as shown by numerous gas flares. On going studies are addressed to: 1. re-examining the structural setting of the study area, in order to verify a possible structural control on chimney distribution and gas migration; 2. performing geochemical analysis on gas which have been sampled in some key emission points; 3. a quantitative analysis of some selected boreholes well logs (made available through the public VidePi database (www.videpi.com)) aimed to estimate the amount of gas present in sediments. This work presents the preliminary results regarding the latter aspect of our research. In a first instance, for each selected borehole the geophysical logs have been digitized. This procedure consists in a manual picking of curves, in a set system of reference. Static corrections for vertical offset are made at this stage. Logs are then divided by type and converted in common scales, amplifications and units. Every log is resampled in order to cut high frequencies not useful in the comparison with seismic data

    This article reports on findings from a study in 1993-94 on women and sustainable development in Hunza and Nagar districts in the Karakorum mountains of northern Pakistan. The study aims to explore the impact of development on women's work burden and sustainable use of natural resources. Local natural resource management has been a complex system of agro-pastoralist use, with poor yields. Modernization resulted in construction of the Karakorum Highway in 1978 and the Aga Khan Support Program, which mobilized the community in irrigation and agricultural projects. Village organizations were formed as a forum for community decision making and information exchange. These changes resulted in the doubling of household income during 1983-92. Agricultural productivity increased without compromising soil fertility. Livestock herds doubled during 1976-86. The road created the opportunity for new strategies for improving income. Wholesale markets became accessible. Tourism increased, the economy diversified in ways that increased women's income and control of income, and demand for education increased. Women reported that the increased demands on workload were worth the improved standard of living. Gendered work was reallocated, and division of labor changed among women of various ages. Village councils began protecting depleted forest reserves. Men collected wood on the higher slopes, according to anthropomorphic and spiritual beliefs. Women's knowledge of the environment was greater with age and specific to the tasks performed. Men and women did not have permanently fixed gender roles. Women were not exclusive managers of the environment. Women benefited the most from technology that was in their interest and not controlled by men.

    The recent accidents with nuclear powered Russian submarines, such as the Kursk and the K-159, that took place in the Arctic Seas, give rise to high concerns of the public and the media about the radioactive contamination of marine ecosystems and radiological safety of the European population. Those accidents were preceded by decades of discharges of radioactive liquid effluents into coastal seas of Europe and the dumping of packed radioactive waste into the North Atlantic. Being Portugal one country with high consumption rate of seafood caught in its own coastal waters as well as in far seas including the Ar tic seas, the investigation of the radioactive contamination of fish was investigated. Analysis of fish from the Sea of Labrador, Sea of Iceland and Barents Sea, has shown that gamma-emitting radionuclides of artificial origin are in general not detected. The only gamma emitting radionuclide present is Cs-137, in concentrations not higher than 0.3 Bq/kg. This radionuclide originates in the deposition of radioactive fallout following nuclear weapon tests performed in the fifties and sixties. Radionuclides in fish from northern regions and in fish from the Portuguese coast generally are present in concentrations lower than those currently reported for fish from the Irish Sea and the Baltic Sea, impacted with the discharges of radioactive waste from Sellafield and the deposition of fallout from Chernobyl, respectively. Nevertheless, the potential for future accidents and the radioactive waste dumped into the North Atlantic may in the future modify this scenario and potentially increase the currently very low radionuclide concentration in fish included in the Portuguese diet. Therefore, the research and radiological surveillance must be maintained in order to monitor the radiological risk and to ensure the quality of food available to consumers. (author)

    The incidence of skin cancer is increasing worldwide. For decades, opportunistic melanoma screening has been carried out to respond to this burden. However, despite potential positive effects such as reduced morbidity and mortality, there is still a lack of evidence for feasibility and effectiveness of organized skin cancer screening. The main aim of the project was to evaluate the feasibility of systematic skin cancer screening. In 2003, the Association of Dermatological Prevention was contracted to implement the population-based SCREEN project (Skin Cancer Research to Provide Evidence for Effectiveness of Screening in Northern Germany) in the German state of Schleswig-Holstein. A two-step program addressing malignant melanoma and nonmelanocytic skin cancer was implemented. Citizens (aged ≥ 20 years) with statutory health insurance were eligible for a standardized whole-body examination during the 12-month study period. Cancer registry and mortality data were used to assess first effects. Of 1.88 million eligible citizens, 360,288 participated in SCREEN. The overall population-based participation rate was 19%. A total of 3103 malignant skin tumors were found. On the population level, invasive melanoma incidence increased by 34% during SCREEN. Five years after SCREEN a substantial decrease in melanoma mortality was seen (men: observed 0.79/100,000 and expected 2.00/100,000; women: observed 0.66/100,000 and expected 1.30/100,000). Because of political reasons (resistance as well as lack of support from major German health care stakeholders), it was not possible to conduct a randomized controlled trial. The project showed that large-scale systematic skin cancer screening is feasible and has the potential to reduce skin cancer burden, including mortality. Based on the results of SCREEN, a national statutory skin cancer early detection program was implemented in Germany in 2008. Copyright © 2010 American Academy of Dermatology, Inc.

    Possession states are still commonly seen in developing societies as acceptable cultural phenomena in normal persons as well as in those with psychiatric illness. 'Possession' is defined here as the experience of being taken over, controlled or occupied by another spirit or force. This is a descriptive cross-sectional study of possession states among psychiatric patients, general population and popular adepts in Northern Sri Lanka, using semi-structured questionnaires and clinical observations. Thirty psychiatric patients were identified as having possession states. They were compared with 30 controls each from the general population admitted to a general hospital outpatient department and selected popular adepts in the community. The latter are individuals who are well known as having possession states. An analysis of social factors and other variables showed that education, marital status, age, employment, strength of belief, alterations in personality, past or family psychiatric history, previous exposure to similar phenomena, help-seeking behavior and treatment outcome differed between the three groups. Religion of the subjects or recent changes in values showed no correlation with possession while monetary gain from possession states showed only a partial correlation. Western medical treatment was of value only when possession states were seen as part of psychotic illness. Possession is a spectrum of experiential and behavioral phenomena seen in culturally acceptable form in normal people, popular adepts, as well as manifestations of psychotic illness. Possession states which fit normal cultural stereotypes could, if necessary, be better managed by traditional methods. However, clinicians need to be familiar with culturally abnormal forms of possession which are manifestations of psychotic illness that benefit from western psychiatric treatment. (c) 2008 S.

    During the TopoIberia experiment, a total of 26 seismic broadband stations were recording in northern Morocco, providing for the first time extended regional coverage for investigating structure and seismotectonics of the southern branch of the Betic-Rif arc, its foreland, and the Atlas domain. Here, we analyze P-to-S converted waves in teleseismic receiver functions to infer gross crustal properties as thickness and Vp/Vs ratio. Strong lateral variations of the crustal thickness are observed throughout the region. Crustal thicknesses vary between 22 and 44 km and display a simple geographic pattern that divides the study area into three domains: entire northwestern Morocco underlain by a thickened crust with crustal thicknesses between 35 and 44 km; northeastern Morocco affected by significant crustal thinning, with crustal thicknesses ranging from 22 to 30 km, with the shallowest Moho along the Mediterranean coast; and an extended domain of 27-34 km thick crust, farther south which includes the Atlas domain and its foreland regions. Vp/Vs ratios show normal values of ˜1.75 for most stations except for the Atlas domain, where several stations give low Vp/Vs ratios of around 1.71. The very sharp transition from thick crust in northwestern Morocco to thin crust in northeastern Morocco is attributed to regional geodynamics, possibly the realm of present-day subcrustal dynamics in the final stage of western Mediterranean subduction. Crustal thicknesses just slightly above 30 km in the southern domain are intriguing, showing that high topography in this region is not isostatically compensated at crustal level.

    International Nuclear Information System (INIS)

    Constantin, D.

    2005-01-01

    This paper discusses supply challenges in relation to Northern gas availability in Arctic Canada and Alaska. A background of BP Canada Energy Company was provided. It was suggested that gas from traditional North American basins would not meet demand, and that incremental sources of supply would be needed. A map of traditional and non-tradition supply sources was presented along with details of supply and infrastructure investment requirements from 2003-2025. The roles of producers, local distribution companies, pipelines and policy makers in infrastructure development were examined. Potential resources in Alaska and the Mackenzie Delta were discussed, along with details of the Mackenzie Valley Pipeline project and exploration activities. Alaska's North Slope gas resource was reviewed. Several large projects devolving from the Alaska Gas Pipeline represent an anticipated total investment of $20 billion. Various regulatory and economic conditions necessary for the successful completion of the project include the Alaska Fiscal Contract; Alaska gas provisions in the Federal Energy Bill; details of the Canadian regulatory process; and cost reductions and market outlooks. It was concluded that the Alaska Gas Pipeline would provide thousands of jobs and provide stability of long-term gas prices as well as meeting North America's energy needs. In addition, the pipeline would provide $16 billion in Canadian government revenues and $40 billion in US government revenues. The pipeline would provide 4.5 billion cubic feet per day of clean energy, with half the carbon dioxide emissions of coal. It would also provide hundreds of billions of dollars in consumer savings. tabs, figs

    Estimate levels of and identify factors contributing to child malnutrition in Tigray, Northern Ethiopia. Cross-sectional survey. Rural communities from four zones of Tigray. Three hundred and eighteen under five children representing 587 randomly selected households were included. Among the children surveyed, 46.9%, 33.0% and 11.6% were stunted,underweight and wasted, respectively. Older children were more likely to be undernourished. Stunting increases from 16% in the second half of the first year to 53% in children 24 months and older. Similarly, underweight increases from 10% in the first six months to 36.5% in children aged 24 months and older. A very high proportion of the mothers (80%) initiated feeding of newborns with pre-lacteal feeds primarily butter or water. Family foods and cereal-based porridge were the main complementary foods after six months. Child age, maternal anthropometric characteristics, inadequate complementary foods, the use of prelacteal feeds and area of residence were the main contributing factors to child undernutrition. Undernutrition gets worse as the children grow older. The energy and nutrient density of the complementary foods are low as the foods were prepared from a limited number of local staple cereals without the addition of sugar, fat/oil or animal products. More importantly, these foods are diluted with water to reduce their viscosity. This makes the quality and quantity of the foods insufficient to prevent stunting and underweight. Promotion of traditional household technologies such as germination and fermentation may be affordable measures to improve the quality of the complementary foods. Thus, sustained nutrition education programmes focusing on appropriate complementary feeding practices are recommended.

  16. Spatial models of Northern Bobwhite populations for conservation planning

    2007-01-01

    Since 1980, northern bobwhite (Colinus virginianus) range-wide populations declined 3.9% annually. Within the West Gulf Coastal Plain Bird Conservation Region in the south-central United States, populations of this quail species have declined 6.8% annually. These declines sparked calls for land use change and prompted implementation of various conservation practices. However, to effectively reverse these declines and restore northern bobwhite to their former population levels, habitat conservation and management efforts must target establishment and maintenance of sustainable populations. To provide guidance for conservation and restoration of habitat capable of supporting sustainable northern bobwhite populations in the West Gulf Coastal Plain, we modeled their spatial distribution using landscape characteristics derived from 1992 National Land Cover Data and bird detections, from 1990 to 1994, along 10-stop Breeding Bird Survey route segments. Four landscape metrics influenced detections of northern bobwhite: detections were greater in areas with more grassland and increased aggregation of agricultural lands, but detections were reduced in areas with increased density of land cover edge and grassland edge. Using these landscape metrics, we projected the abundance and spatial distribution of northern bobwhite populations across the entire West Gulf Coastal Plain. Predicted populations closely approximated abundance estimates from a different cadre of concurrently collected data but model predictions did not accurately reflect bobwhite detections along species-specific call-count routes in Arkansas and Louisiana. Using similar methods, we also projected northern bobwhite population distribution circa 1980 based on Land Use Land Cover data and bird survey data from 1976 to 1984. We compared our 1980 spatial projections with our spatial estimate of 1992 populations to identify areas of population change. Additionally, we used our projection of the spatial

  17. Euroscepticism in Italy: Evolution of Northern League Political Program

    Directory of Open Access Journals (Sweden)

    Oleg N. Barabanov

    2015-01-01

    Full Text Available Abstract: The article examines the key stages of the establishment of Italy’s Northern League as a rightwing hard eurosceptic party. Being initially a continual supporter of European integration and considering the transition to common currency as an opportunity available only to northern regions, which could secede and form an independent state, Northern League after losing the main point of its political agenda when the whole Italy joined the Economic and Monetary Union in 1998, became a eurosceptically-oriented party, which it is up to now. The authors dwell on the focal points of the party’s anti-EU program: Italy’s exit from the eurozone, the formation of Europe of macroregions, the reformation of supranational institutes and decision-making procedures. However, while confronting the Northern League policy with that of National Front in France and UKIP in the United Kingdom, the authors come to the conclusion that Euroscepticism for the former is just a sign of the shift in priorities rather than a strategy as for the latter. This can be explained by the fact that National Front and UKIP are still to fight for the place in the national mainstream, while Northern League has become its integral part long before. Nevertheless, under the new leadership of M.Salvini Northern League managed to become the fourth party on the national level according to the results of European parliament elections in 2014 and established itself as a significant power opponent to EU policy on a number of important issues, such as anti-Russian sanctions. Moreover, frequent visits of party members to Moscow and the party’s outspoken support of Russia on Crimea’s entrance into the Russian Federation provide an opportunity to consider Northern League a potential conductor of Russian interests in the European Union.

  18. All Christians? Experiences of science educators in Northern Ireland

    2010-03-01

    In this paper we respond to Staver's article (this issue) on an attempt to resolve the discord between science and religion. Most specifically, we comment on Staver's downplaying of difference between Catholics and Protestants in order to focus on the religion-science question. It is our experience that to be born into one or other of these traditions in some parts of the world (especially Northern Ireland) resulted in starkly contrasting opportunities, identities and practices in becoming and being science educators. The paper starts with a short contextual background to the impact of religion on schooling and higher education in Northern Ireland. We then explore the lives and careers of three science/religious educators in Northern Ireland: Catholic (Jim) and Protestant (Ivor) males who are contemporaries and whose experience spans pre-Troubles to post-conflict and a Catholic female (Colette) who moved to Northern Ireland during the Troubles as a teenager. Finally, we discuss the situation regarding the teaching of creationism and evolution in Northern Ireland—an issue has recently generated high public interest. The Chair of the Education Committee of the Northern Ireland Assembly recently stated that "creationism is not for the RE class because I believe that it can stand scientific scrutiny and that is a debate which I am quite happy to encourage and be part of…" (News Letter 2008). It could be the case that the evolution debate is being fuelled as a deliberate attempt to undermine some of the post-conflict collaboration projects between schools and communities in Northern Ireland.

    Glaciers are widely recognized as key indicators of climate change. Recent evidence suggests an acceleration of glacier mass loss in several key mountain regions. Glacier recession implies landscape changes in the glacial zone, the origin of new lakes and activation of natural disaster processes, catastrophic mudflows, ice avalanches, outburst floods, etc. The absence or inadequacy of such information results in financial and human losses. A more comprehensive evaluation of glacier changes is imperative to assess ice contributions to global sea level rise and the future of water resources from glacial basins. One of the urgent steps is a full inventory of all ice bodies and their changes. The first estimation of glacier state and glacier distribution on the territory of the former Soviet Union has been done in the USSR Glacier Inventory (UGI) published in 1965–1982. The UGI is based on topographic maps and air photos and reflects the status of the glaciers in the 1940s–1970s. There is information about 28 884 glaciers with an area of 7830.75 km 2 in the inventory. It covers 25 glacier systems in Northern Eurasia. In the 1980s the UGI has been transformed into digital form as a part of the World Glacier Inventory (WGI). Recent satellite data provide a unique opportunity to look again at these glaciers and to evaluate changes in glacier extent for the second part of the 20th century. About 15 000 glacier outlines for the Caucasus, Polar Urals, Pamir Alay, Tien Shan, Altai, Kamchatka and Russian Arctic have been derived from ASTER and Landsat imagery and can be used for glacier change evaluation. Results of the analysis indicate the steady trend in glacier shrinkage in all mountain regions for the second part of the 20th century. Glacier area loss for the studied regions varies from 13% (Tien Shan) to 22.3% (Polar Urals). The common driver, most likely, is an increase in summer air temperature. There is also a very large variability in the degree of

    The northern Netherlands has been regarded aseismic until the first earthquakes started in 1986, after more than 25 years of gas production from the one of the largest on-shore gas-fields in the World, the Groningen field, and accompanying smaller gas fields. Due to the shallow sources, at approximately 3 km depth, even small magnitude events cause considerable damage to buildings in the region. Since the largest recorded event in the Groningen field in 2012 with ML= 3,6, more than 30.000 damage claims were received by the mining company. Since 1995 a seismic monitoring network is operational in the region, consisting of 8 200m deep boreholes with 4 levels of 3C 4,5 Hz geophones. The network was designed for a location threshold of ML=1,5 over a 40x 80 km region. Average station separation was 20 km. At the end of 2014, 245 events have been recorded with ML ≥ 1,5, out of a total of 1100. Since 2003 a new mining law is in place in the Netherlands, which requires for each gas field in production a seismic risk analysis. Initially, due to the small number of events for specific fields, a general hazard (PSHA) was calculated for all gas-fields and a maximum magnitude was estimated at ML = 3,9. Since 2003 an increase in the activity rate is observed for the Groningen field, leading to the development of new models and a re-assessment of parameters like the maximum magnitude. More recently these models are extended to seismic risk, where also the fragility of the regional buildings is taken into account. Understanding the earthquake process is essential in taking mitigation measures. Continued research is focused on reducing the uncertainties in the hazard and risk models and is accompanied by an upgrade of the monitoring network. In 2014 a new dense network was designed to monitor the Groningen gas field in this region (30*40 km) with an average separation of 4 km. This allows an improved location threshold (M>0,5) and location accuracy (50-100m). A detailed P- and S

    A survey on stroke was conducted to evaluate the incidence of intracerebral hemorrhage and the prevalence of risk factors. The subjects, comprising those patients who suffesed a stroke, were registered on the Northern Hokkaido Stroke Study between July 2002 and June 2006. The severity of their illness was rated by the National Institutes of Health Stroke Scale (NIHSS) at hospital admission, while their outcome was determined by the mortality within 3 months and the mRS (modified Rankin Scale score). Of the 1,046 registered stroke patients, 271 (25.9%) were found to suffer from cerebral hemorrhage. Their mean age was 70.3±11.7 years; male-to-female ratio, 154/117; mean NIHSS at admission, 11.8±8.1; mortality within 3 months, 19.2%; and percentage who regained independence within 3 months (mRS: ≤2), 32.5%. A history of hypertension was found in 72.6%, and 13.7% had no treatment. MRI (T2*) revealed micro-hemorrhage outside the lesions in 67.5%. Forty-seven patients (17.3%) were taking anti-platelet agents at the onset of intracerebral hemorrhage. There was no significant difference between the mortalities of the anti-platelet-agent-users and non-users but the percentage of those regaining independence within 3 months was 19.1% for the users against 37.3% for the non-users (p=0.0177), with a significantly poor outcome in the user group. In northern Hokkaido, the incidence of cerebral hemorrhage remains high, and the percentage of those with poorly controlled or uncontrolled hypertension was 30%. These findings suggest a need to educate not only the inhabitants themselves but also the physicians engaged in their care. (author)

    Seismic, stratigraphic, structural, and geochemical data from the Altiplano, northern Subandean, and northern plains of Bolivia were interpreted in order to evaluate the exploration potential of each province. Identification of three possible source rock intervals, primarily the Devonian and secondarily the Permian and Cretaceous, was used as the basis for recognizing active hydrocarbon systems. For those areas containing source intervals, their analysis revealed that possible reservoir and seal units range in age from Paleozoic to Tertiary; the majority of structures, however, are Eocene or younger. With these general concepts in mind, traps were identified in all three sedimentary provinces. In the northern Altiplano, the most prospective area is along the eastern margin near a southwest and west-vergent thrust belt where hanging-wall anticlines and a warped Eocene-Oligocene(.) unconformity surface form the most likely potential traps. In the central and southern Altiplano, both thrust-related and wrench-related structures present possible exploration targets. In the northern Subandean and Beni plains north of the Isiboro-Chapare area, traps can be classified into two broad groups. First, there are a wide variety of structural traps within the northern Subandean thrust belt, the most attractive of which are footwall structures that have been shielded from surface flushing by hanging-wall strata. Second, in the plains just northeast of the thrust belt, hydrocarbons sourced from the remnant Paleozoic basin may have migrated onto the Isarsama and Madidi highs.

  5. Geomorphology and landscape organization of a northern peatland complex

    2012-12-01

    The geomorphic evolution of northern peatlands is governed by complex ecohydrological feedback mechanisms and associated hydro-climatic drivers. For example, prevailing models of bog development (i.e. Ingram's groundwater mounding hypothesis and variants) attempt to explicitly link bog dome characteristics to the regional climate based on analytical and numerical models of lateral groundwater flow and the first-order control of water table position on rates of peat accumulation. In this talk I will present new results from quantitative geomorphic analyses of a northern peatland complex at the De Beers Victor diamond mine site in the Hudson Bay Lowlands of northern Ontario. This work capitalizes on spatially-extensive, high-resolution topographic (LiDAR) data to rigorously test analytical and numerical models of bog dome development in this landscape. The analysis and discussion are then expanded beyond individual bog formations to more broadly consider ecohydrological drivers of landscape organization, with implications for understanding and modeling catchment-scale runoff response. Results show that in this landscape, drainage patterns exhibit relatively well-organized characteristics consistent with observed runoff responses in six gauged research catchments. Interpreted together, the results of these geomorphic and hydrologic analyses help refine our understanding of water balance partitioning among different landcover types within northern peatland complexes. These findings can be used to help guide the development of appropriate numerical model structures for hydrologic prediction in ungauged peatland basins of northern Canada.

    Background We sought to compare the epidemiologic features of Kawasaki disease (KD) in three Northern European countries and Japan. Methods Data were obtained from discharge databases for hospitals in Finland, Norway, and Sweden from 1999–2009 and from nationwide epidemiologic surveys in Japan from 1998–2008. Annual incidence for each country was calculated using regional census data. Results During the 11-year period, 1,390 KD patients were recorded in the registries of the three Northern European countries. Average annual incidence rates per 100,000 children less than 5 years were: Finland 11.4, Norway 5.4, and Sweden 7.4. Overall, 86.4% of Japanese KD patients were less than 5 years compared to only 67.8% in the four Northern European countries (p<0.001). Conclusions The incidence of KD in Northern Europe was constant over the study period and much lower than in Japan. There was a significant age difference between Northern European and Japanese KD patients that remains unexplained. PMID:22726311

    Religion plays a pivotal role in intergroup and interpersonal relationships in Northern Ireland, and individuals traditionally marry within their own religious group. However, 'mixed' marriages between Catholics and Protestants do occur and present an interesting, yet under researched, dynamic within this divided society. Both religion and committed relationships have been associated with physical and psychological health, but little is known about how divergence in religious beliefs within relationships impacts on health. A secondary data analysis of the Northern Ireland cohort of the Understanding Society: the UK Household Longitudinal Study was conducted to investigate the impact of mixed religion relationships on physical and psychological well-being in Northern Ireland. Less than 10% of relationships were mixed religion relationships, and being in a mixed relationship was associated with poorer mental health but not with physical health. Mixed religion relationships in Northern Ireland are relatively uncommon in Northern Ireland, but are an important form of intergroup contact, as such it is important to fully understand the implications for the individuals involved and develop mechanisms to support those individuals psychological well-being.

    Various methods for the spatial analysis of hydrologic data have been developed recently. Here we present results using the conditional probability approach proposed by Keef et al. [Appl. Stat. (2009): 58,601-18] to investigate spatial interdependence in extreme river flows in Scotland. This approach does not require the specification of a correlation function, being mostly suitable for relatively small geographical areas. The work is motivated by the Flood Risk Management Act (Scotland (2009)) which requires maps of flood risk that take account of spatial dependence in extreme river flow. The method is based on two conditional measures of spatial flood risk: firstly the conditional probability PC(p) that a set of sites Y = (Y 1,...,Y d) within a region C of interest exceed a flow threshold Qp at time t (or any lag of t), given that in the specified conditioning site X > Qp; and, secondly the expected number of sites within C that will exceed a flow Qp on average (given that X > Qp). The conditional probabilities are estimated using the conditional distribution of Y |X = x (for large x), which can be modeled using a semi-parametric approach (Heffernan and Tawn [Roy. Statist. Soc. Ser. B (2004): 66,497-546]). Once the model is fitted, pseudo-samples can be generated to estimate functionals of the joint tails of the distribution of (Y,X). Conditional return level plots were directly compared to traditional return level plots thus improving our understanding of the dependence structure of extreme river flow events. Confidence intervals were calculated using block bootstrapping methods (100 replicates). We report results from applying this approach to a set of four rivers (Dulnain, Lossie, Ewe and Ness) in Northern Scotland. These sites were chosen based on data quality, spatial location and catchment characteristics. The river Ness, being the largest (catchment size 1839.1km2) was chosen as the conditioning river. Both the Ewe (441.1km2) and Ness catchments have

    Results of an initial study indicated that the most significant factor affecting retention for Physiotherapists in Northern Ontario was perceived opportunity for career development. A follow-up study was completed two years later to determine: 1) actual job turnover and regional attrition among physiotherapists in Northern Ontario; and 2) the predictive validity of variables identified in the first study regarding job turnover and regional attrition. Job turnover occurred in 29.5% of those sampled and the regional attrition rate was 12%. Discriminant function analysis revealed factors affecting job turnover and regional attrition including professional experience, practice location, opportunity for career development and size of community of residence. Based on previous intention, indicated by participants, follow-up revealed that the initial study correctly predicted 77.5% of those who changed their jobs and 74.1% of those who left Northern Ontario. Identified factors provide direction for the development of strategies for recruitment and retention of physiotherapists.

    This research programme has been under way since 1990 to study the long-term synergistic effects of air pollutants and changing climatic conditions on the northern forest ecosystem and to increase the knowledge of climatic change and its consequences for the fragile northern nature. Ecological, physiological, morphological and biochemical methods have been used to study the responses of forest trees, dwarf shrubs, lichens and soil biology to environmental changes. The research programme is divided into four subprojects concentrating on different ecosystem levels. The subprojects are: (1) life, growth and survival strategies of northern dwarf shrubs under the pressure of a changing environment, (2) forest trees under the impact of air pollutants, increasing CO{sub 2} and UV-B, (3) susceptibility of lichens to air pollution and climatic change and (4) impact of elevated atmospheric CO{sub 2} and O{sub 3} on soil biology with special reference to carbon allocation and N fixation in symbiotic systems. This report summarizes the results of short-term experiments which showed many ecological and physiological changes in almost all elements of the northern boreal forests. These species-level measurements focused on the key species of the northern boreal forest, which have been thought to be useful in large-scale ecosystem experiments and modelling. The results will also facilitate the further studies on the patterns of plant species distribution and northern ecosystem function with respect to the environmental parameters that are expected to change along with global change (e.g. temperature, airchemistry, UV-B, snow condition)

    The northern plains of Mars cover nearly a third of the planet and constitute the planet's broadest region of lowlands. Apparently formed early in Mars' history, the northern lowlands served as a repository both for sediments shed from the adjacent ancient highlands and for volcanic flows and deposits from sources within and near the lowlands. Geomorphic evidence for extensive tectonic deformation and reworking of surface materials through release of volatiles occurs throughout the northern plains. In the polar region, Planum Boreum contains evidence for the accumulation of ice and dust, and surrounding dune fields suggest widespread aeolian transport and erosion. The most recent regional- and global-scale maps describing the geology of the northern plains are largely based on Viking Orbiter image data (Dial, 1984; Witbeck and Underwood, 1984; Scott and Tanaka, 1986; Greeley and Guest, 1987; Tanaka and Scott, 1987; Tanaka and others, 1992a; Rotto and Tanaka, 1995; Crumpler and others, 2001; McGill, 2002). These maps reveal highland, plains, volcanic, and polar units based on morphologic character, albedo, and relative ages using local stratigraphic relations and crater counts. This geologic map of the northern plains is the first published map that covers a significant part of Mars using topography and image data from both the Mars Global Surveyor and Mars Odyssey missions. The new data provide a fresh perspective on the geology of the region that reveals many previously unrecognizable units, features, and temporal relations. In addition, we adapted and instituted terrestrial mapping methods and stratigraphic conventions that we think result in a clearer and more objective map. We focus on mapping with the intent of reconstructing the history of geologic activity within the northern plains, including deposition, volcanism, erosion, tectonism, impact cratering, and other processes with the aid of comprehensive crater-density determinations. Mapped areas include all

    Nature tourism has been a growing business sector in the Barents area during the recent decades. With the purpose to develop nature tourism in a sustainable way, a cooperation project ABCGheritage - Arctic Biological, Cultural and Geological Heritage has been carried out. Project has received partial funding from the EU Kolarctic ENPI program. In the geoheritage part of the project the main activities were aimed to develop pro-environmental ways of geotourism in the area. The three main participants in the geoheritage part of the project are the Geological Survey of Finland, Northern Finland Office, the Geological Institute of the Kola Science Centre of the Russian Academy of Sciences and Bioforsk Soil and Environment from northeastern Norway. The duration of the project is 2012-2014 and most of the work has already been completed even if most of the results are not published yet. Totally ten different tasks have been implemented in the geological part of the project. The largest task has been the preparation of a geological outdoor map and guide book of the Khibiny Tundra locating in the central part of the Kola Peninsula. In Finland already 11 such maps have been published, and the experiences gained during their production have been used in this project, too. Geological heritage trails to the Khibiny Tundra have also been created and they will be drawn on the map. The second concrete result is the Barents Tour for Geotourist -guide, which will be published as a guide book, web pages and an exhibition. The route comprises ca 35 best geological demonstration sites along the circle route from northern Finland to northeastern Norway, from there to Kola Peninsula and then back to Finland. Information of the route will be available for all interested travelers. In addition to the geological outdoor map of the Khibiny Tundra and "Barents Tour for Geotourists"-guide, the primary outputs of the project are the geological nature trails on the field, geological

    2014-05-01

    Full Text Available Traditional agrosilvopastoral systems have been an important component of the farming systems and livelihoods of thousands of ethnic minority people in the uplands of Mainland Southeast Asia. Drawing on a combination of qualitative and participatory inquiries in nine ethnic minority communities, this study emphasizes the complex articulation of local farmers’ knowledge which has been so far excluded from governmental development and conservation policies in the northern uplands of Thailand and Laos. Qualitative analysis of local knowledge systems is performed using the Agroecological Knowledge Toolkit (AKT5 software. Results show that ethnic minorities in the two countries perceive large ruminants to be a highly positive component of local forest agro-ecosystems due to their contribution to nutrient cycling, forest fire control, water retention, and leaf-litter dispersal. The knowledge and perceptions of agrosilvopastoral farmers are then contrasted with the remarkably different forestry policy frameworks of the two countries. We find that the knowledge and diversity of practices exercised by ethnic minority groups contrasts with the current simplified and negative image that government officials tend to construct of agrosilvopastoral systems. We conclude that local knowledge of forest-livestock systems can offer alternative or complementary explanations on ecological cause-and-effect relationships which may need further scientific investigation and validation.

    2012-07-01

    Arid zones of northern Venezuela are represented by isolated areas, important from an ornithological and ecological perspective due to the occurrence of restricted-range species of birds. We analysed the prevalence and molecular diversity of haemosporidian parasites of wild birds in this region by screening 527 individuals (11 families and 20 species) for parasite mitochondrial DNA. The overall prevalence of parasites was 41%, representing 17 mitochondrial lineages: 7 of Plasmodium and 10 of Haemoproteus. Two parasite lineages occurred in both the eastern and western regions infecting a single host species, Mimus gilvus. These lineages are also present throughout northern and central Venezuela in a variety of arid and mesic habitats. Some lineages found in this study in northern Venezuela have also been observed in different localities in the Americas, including the West Indies. In spite of the widespread distributions of some of the parasite lineages found in northern Venezuela, several, including some that are relatively common (e.g. Ven05 and Ven06), have not been reported from elsewhere. Additional studies are needed to characterize the host and geographical distribution of avian malaria parasite lineages, which will provide a better understanding of the influence of landscape, vector abundance and diversity, and host identity on haemosporidian parasite diversity and prevalence.

  5. TOURISM OFFER IN ROMANIA AND NORTHERN TRANSYLVANIA – TERRITORIAL DISPARITIES

    Directory of Open Access Journals (Sweden)

    LUJZA TÜNDE COZMA

    2014-11-01

    Full Text Available Tourism Offer in Romania and Northern Transylvania – Territorial Disparities. Explaining spatiality has been in the focus of tourism geographers since the beginnings, and the examination of spatial processes still represents a major challenge for researchers, knowing that there is no segment in the functioning of society in which spatiality is not present. The approach was to consider tourism as a complex spatial phenomenon, in order to explain better its processes. Romanian literature abounds in descriptive research of travel and tourism, discussing quantitative and qualitative issues, attraction classifications, tourism potential and geographic dispersal. However, a serious deficit manifests in explanatory research. Therefore, this paper aims to analyze the territorial disparities in the tourism offer of Romania, in generally and of Northern Transylvania in particularly, in the light of current trends characterizing the national tourism industry. Besides spatial characteristics, this paper also deals with tourism penetration on regional level, and territorial concentration of accommodation capacity in the region of Northern Transylvania. The results show that in the moderately-high saturated destination of Northern Transylvania the accommodation capacity in use is spatially concentrated and only a few localities can be regarded as the strongholds of the accommodation basis. The study brings novel results especially for tourism planning, but also provides a basis for further research.

    Yang, Jun; Pei, Ying; Zhang, Yanwei; Ge, Quansheng

    2017-04-01

    This study was conducted using daily precipitation records gathered at 37 meteorological stations in northern Xinjiang, China, from 1961 to 2010. We used the extreme value theory model, generalized extreme value (GEV) and generalized Pareto distribution (GPD), statistical distribution function to fit outputs of precipitation extremes with different return periods to estimate risks of precipitation extremes and diagnose aridity-humidity environmental variation and corresponding spatial patterns in northern Xinjiang. Spatiotemporal patterns of daily maximum precipitation showed that aridity-humidity conditions of northern Xinjiang could be well represented by the return periods of the precipitation data. Indices of daily maximum precipitation were effective in the prediction of floods in the study area. By analyzing future projections of daily maximum precipitation (2, 5, 10, 30, 50, and 100 years), we conclude that the flood risk will gradually increase in northern Xinjiang. GEV extreme value modeling yielded the best results, proving to be extremely valuable. Through example analysis for extreme precipitation models, the GEV statistical model was superior in terms of favorable analog extreme precipitation. The GPD model calculation results reflect annual precipitation. For most of the estimated sites' 2 and 5-year T for precipitation levels, GPD results were slightly greater than GEV results. The study found that extreme precipitation reaching a certain limit value level will cause a flood disaster. Therefore, predicting future extreme precipitation may aid warnings of flood disaster. A suitable policy concerning effective water resource management is thus urgently required.

    Nigeria, a country located in the Western part of Africa has been the site of numerous kingdoms and tribal states over the millennia and is divided in to Northern and Southern parts with the Hausa-Fulani’s, a diverse but culturally homogeneous people living in the northern part of Nigeria. The vernacular architecture of the Northern Nigeria (VANN) is perhaps one of the least known but most beautiful of the medieval age, over the centuries a tradition of fine architecture has flourished in the area, the variety and quality of buildings are bound to generate much delight and enthusiasm in anyone who is interested in buildings. Many of their early buildings such as mosques and palaces are bright and colorful. This architectural style is known as Tubali which means the traditional architecture in the Hausa language and globally known as Vernacular Architecture (VA). VANN has many unique features which distinguish it from any other architecture. All buildings, be it modern or old has an impact on the environment; hence the need for sustainable measures and practices regarding such buildings. The aim of this research paper is to examine the features of VANN in the light of sustainability. Reviewed literatures were used to identify the various features of the Vernacular Architecture in the Northern Nigeria which were critically examined in the light of sustainability and its concept. The result showcased the various features of VANN in the light of sustainability and also discussed the factors hindering the sustainable endeavors of VANN with respect to such features.

    2018-05-01

    This study was conducted using daily precipitation records gathered at 37 meteorological stations in northern Xinjiang, China, from 1961 to 2010. We used the extreme value theory model, generalized extreme value (GEV) and generalized Pareto distribution (GPD), statistical distribution function to fit outputs of precipitation extremes with different return periods to estimate risks of precipitation extremes and diagnose aridity-humidity environmental variation and corresponding spatial patterns in northern Xinjiang. Spatiotemporal patterns of daily maximum precipitation showed that aridity-humidity conditions of northern Xinjiang could be well represented by the return periods of the precipitation data. Indices of daily maximum precipitation were effective in the prediction of floods in the study area. By analyzing future projections of daily maximum precipitation (2, 5, 10, 30, 50, and 100 years), we conclude that the flood risk will gradually increase in northern Xinjiang. GEV extreme value modeling yielded the best results, proving to be extremely valuable. Through example analysis for extreme precipitation models, the GEV statistical model was superior in terms of favorable analog extreme precipitation. The GPD model calculation results reflect annual precipitation. For most of the estimated sites' 2 and 5-year T for precipitation levels, GPD results were slightly greater than GEV results. The study found that extreme precipitation reaching a certain limit value level will cause a flood disaster. Therefore, predicting future extreme precipitation may aid warnings of flood disaster. A suitable policy concerning effective water resource management is thus urgently required.

  8. Does urban vegetation mitigate air pollution in northern conditions?

    Setälä, Heikki; Viippola, Viljami; Rantalainen, Anna-Lea; Pennanen, Arto; Yli-Pelkonen, Vesa

    2013-01-01

    It is generally accepted that urban vegetation improves air quality and thereby enhances the well-being of citizens. However, empirical evidence on the potential of urban trees to mitigate air pollution is meager, particularly in northern climates with a short growing season. We studied the ability of urban park/forest vegetation to remove air pollutants (NO 2 , anthropogenic VOCs and particle deposition) using passive samplers in two Finnish cities. Concentrations of each pollutant in August (summer; leaf-period) and March (winter, leaf-free period) were slightly but often insignificantly lower under tree canopies than in adjacent open areas, suggesting that the role of foliage in removing air pollutants is insignificant. Furthermore, vegetation-related environmental variables (canopy closure, number and size of trees, density of understorey vegetation) did not explain the variation in pollution concentrations. Our results suggest that the ability of urban vegetation to remove air pollutants is minor in northern climates. -- Highlights: ► The ability of northern urban vegetation to remove air pollutants is minor. ► Vegetation-related environmental variables had no effect on air pollution levels. ► The ability of vegetation to clean air did not differ between summer and winter. ► Dry deposition passive samplers proved applicable in urban air pollution study. -- The ability of urban vegetation to remove air pollutants seems to be minor in northern climates

    Vukic, Adele; Keddy, Barbara

    2002-12-01

    This paper explicates the nature of outpost nursing work, and/or the day-to-day realities of northern nursing practice in a primary health care setting in Canada. The study was carried out to systematically explore the work of nurses in an indigenous setting. Institutional ethnography, pioneered by Dorothy Smith was the methodology used to guide this research. The theoretical perspective of this methodology does not seek causes or links but intends to explicate visible practices. It is intended to explicate the social organization of specific discourses that inform work processes of nurses working in remote indigenous communities. The data originated from various sources including spending 2 weeks in a northern remote community shadowing experienced nurses, taking field notes and audio taping interviews with these nurses. One of the two researchers was a northern practice nurse for many years and has had taught in an outpost nursing programme. As part of the process, texts were obtained from the site as data to be incorporated in the analysis. The lived experiences have added to the analytical understanding of the work of nurses in remote areas. Data uncovered documentary practices inherent to the work setting which were then analysed along with the transcribed interviews and field notes derived from the on-site visit. Identifying disjuncture in the discourse of northern nursing and the lived experience of the nurses in this study was central to the research process. The results indicated that the social organization of northern community nursing work required a broad generalist knowledge base for decision making to work effectively within this primary health care setting. The nurse as 'other' and the invisibility of nurses' work of building a trusting relationship with the community is not reflected in the discourse of northern nursing. Trust cannot be quantified or measured yet it is fundamental to working effectively with the community. The nurses in this study

  8. Water Ice Albedo Variations on the Martian Northern Polar Cap

    Science.gov (United States)

    Hale, A. S.; Bass, D. S.; Tamppari, L. K.

    2003-01-01

    The Viking Orbiters determined that the surface of Mars northern residual cap is water ice. Many researchers have related observed atmospheric water vapor abundances to seasonal exchange between reservoirs such as the polar caps, but the extent to which the exchange between the surface and the atmosphere remains uncertain. Early studies of the ice coverage and albedo of the northern residual Martian polar cap using Mariner 9 and Viking images reported that there were substantial internannual differences in ice deposition on the polar cap, a result which suggested a highly variable Martian climate. However, some of the data used in these studies were obtained at differing values of heliocentric solar longitude (L(sub s)). Reevaluation of this dataset indicated that the residual cap undergoes seasonal brightening throughout the summer, and indicated that this process repeats from year to year. In this study we continue to compare Mariner 9 and Viking Orbiter imaging observations and thermal data of the north residual polar cap to data acquired with Mars Global Surveyor s Mars Orbiter Camera (MOC) instrument. In the current study, our goal is to examine all released data from MGS MOC in the northern summer season, along with applicable TES data in order to better understand the albedo variations in the northern summer and their implications on water transport. To date, work has focused primarily on the MOC dataset. In 1999, data acquisition of the northern polar regions began at L(sub s) = 107, although there was little north polar data acquired from L(sub s)= 107 to L(sub s) = 109. We examined a total of 409 images from L(sub s) = 107 to L(sub s)=148. We have also examined data from 2000 from L(sub s)= 93 to L(sub s)= 110; additional progress is ongoing. Here we present a progress report of our observations, and continue to determine their implications for the Martian water cycle.

  9. Thermal refugia against coral bleaching throughout the northern Red Sea

    KAUST Repository

    Osman, Eslam O.

    2017-10-17

    Tropical reefs have been impacted by thermal anomalies caused by global warming that induced coral bleaching and mortality events globally. However, there have only been very few recordings of bleaching within the Red Sea despite covering a latitudinal range of 15° and consequently it has been considered a region that is less sensitive to thermal anomalies. We therefore examined historical patterns of sea surface temperature (SST) and associated anomalies (1982–2012) and compared warming trends with a unique compilation of corresponding coral bleaching records from throughout the region. These data indicated that the northern Red Sea has not experienced mass bleaching despite intensive Degree Heating Weeks (DHW) of >15°C-weeks. Severe bleaching was restricted to the central and southern Red Sea where DHWs have been more frequent, but far less intense (DHWs <4°C-weeks). A similar pattern was observed during the 2015–2016 El Niño event during which time corals in the northern Red Sea did not bleach despite high thermal stress (i.e. DHWs >8°C-weeks), and bleaching was restricted to the central and southern Red Sea despite the lower thermal stress (DHWs < 8°C-weeks). Heat stress assays carried out in the northern (Hurghada) and central (Thuwal) Red Sea on four key reef-building species confirmed different regional thermal susceptibility, and that central Red Sea corals are more sensitive to thermal anomalies as compared to those from the north. Together, our data demonstrate that corals in the northern Red Sea have a much higher heat tolerance than their prevailing temperature regime would suggest. In contrast, corals from the central Red Sea are close to their thermal limits, which closely match the maximum annual water temperatures. The northern Red Sea harbours reef-building corals that live well below their bleaching thresholds and thus we propose that the region represents a thermal refuge of global importance.

  10. Changes in active eolian sand at northern Coachella Valley, California

    Science.gov (United States)

    Katra, Itzhak; Scheidt, Stephen; Lancaster, Nicholas

    2009-04-01

    Climate variability and rapid urbanization have influenced the sand environments in the northern Coachella Valley throughout the late 20th century. This paper addresses changes in the spatial relationships among different sand deposits at northern Coachella Valley between two recent time periods by using satellite data acquired from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). The approach employed here, involving multispectral thermal infrared (TIR) data and spectral mixture analysis, has shown that the major sand deposits can be spatially modeled at northern Coachella Valley. The "coarse-grained (quartz-rich) sand" deposit is associated with active eolian sand, and the "mixed sandy soil" and "fine-grained (quartz-rich) sand" deposits are associated with inactive eolian sand. The fractional abundance images showed a significant decrease between 2000 and 2006 in the percentage of active sand in the major depositional area for fluvial sediment, the Whitewater River, but also in two downwind areas: the Whitewater and Willow Hole Reserves. The pattern of the active sand appears to be related to variations in annual precipitation (wet and dry years) and river discharge in the northern Coachella Valley. We suggest here that recent human modifications to the major watercourses that supply sand affect the capability of fluvial deposition areas to restore sediments over time and consequently the responses of the sand transport system to climate change, becoming more sensitive to dry years where areas of active sand may shrink, degrade, and/or stabilize faster. The approach utilized in this study can be advantageous for future monitoring of sand in the northern Coachella Valley for management of these and similar environments.

    The Northern Ecological Monitoring and Assessment Network (EMAN-North) has received funding for a proposal submitted to the Northern Ecosystems Initiative (NEI) in January 2001. EMAN-North is a network that coordinates ecological monitoring in northern Canada. Its geographic scope comprises 40 per cent of the geographic area of Canada, including Yukon, Northwest Territories and Nunavut, and an area near Churchill, Manitoba. Funding was awarded because the proposed EMAN-North project addressed the NEI priority of Monitoring Ecosystem Status and Trends, and Ecosystem Impacts of Climate Change. The project was also aimed at improving the network's capacity for long-term ecological monitoring, assessment and reporting. Several activities deal specifically with ecological impacts of climate change. This paper described the need and the context for ecological monitoring in northern Canada and defined a strategic direction for EMAN-North. The project will include many individuals involved in ecological monitoring in the north to deliver information on ecosystem changes to decision-makers and the public. refs., tabs., figs

    Recent trends and projections for future change for the U.S. northern forests suggest that the region's climate is becoming warmer, wetter, and, ironically, drier, with more precipitation occurring as large events, separated by longer periods with no precipitation. However, to date, precipitation manipulation experiments conducted in forest ecosystems represent only ~5% of all such experiments worldwide, and our understanding of how the mesic-adapted northern forest will respond to greater frequency and intensity of drought in the future is especially poor. Several important challenges have hampered previous research efforts to conduct forest drought experiments and draw robust conclusions, including difficulties in reducing water uptake by deep and lateral tree roots, logistical and financial constraints to establishing and maintaining large-scale field experiments, and the lack of standardized approaches for determining the appropriate precipitation manipulation treatment (e.g., amount and timing of throughfall displacement), designing and constructing the throughfall displacement infrastructure, identifying key response variables, and collecting and analyzing the field data. The overarching goal of this project is to establish a regional research coordination network - Northern Forest DroughtNet - to investigate the impacts of changes in the amount and distribution of precipitation on the hydrology, biogeochemistry, and carbon (C) cycling dynamics of northern temperate forests. Specific objectives include the development of a standard prototype for conducting precipitation manipulation studies in forest ecosystems (in collaboration with the international DroughtNet-RCN) and the implementation of this prototype drought experiment at the Hubbard Brook Experimental Forest. Here, we present the advances made thus far towards achieving the objectives of Northern Forest DroughtNet, plans for future work, and an invitation to the larger scientific community interested

    The broadly east-west trending, Late Neoproterozoic Bemarivo Belt in northern Madagascar has been re-surveyed at 1:100 000 scale as part of a large multi-disciplinary World Bank-sponsored project. The work included acquisition of 14 U-Pb zircon dates and whole-rock major and trace element geochemical data of representative rocks. The belt has previously been modelled as a juvenile Neoproterozoic arc and our findings broadly support that model. The integrated datasets indicate that the Bemarivo Belt is separated by a major ductile shear zone into northern and southern "terranes", each with different lithostratigraphy and ages. However, both formed as Neoproterozoic arc/marginal basin assemblages that were translated southwards over the north-south trending domains of "cratonic" Madagascar, during the main collisional phase of the East African Orogeny at ca. 540 Ma. The older, southern terrane consists of a sequence of high-grade paragneisses (Sahantaha Group), which were derived from a Palaeoproterozoic source and formed a marginal sequence to the Archaean cratons to the south. These rocks are intruded by an extensive suite of arc-generated metamorphosed plutonic rocks, known as the Antsirabe Nord Suite. Four samples from this suite yielded U-Pb SHRIMP ages at ca. 750 Ma. The northern terrane consists of three groups of metamorphosed supracrustal rocks, including a possible Archaean sequence (Betsiaka Group: maximum depositional age approximately 2477 Ma) and two volcano-sedimentary sequences (high-grade Milanoa Group: maximum depositional age approximately 750 Ma; low grade Daraina Group: extrusive age = 720-740 Ma). These supracrustal rocks are intruded by another suite of arc-generated metamorphosed plutonic rocks, known as the Manambato Suite, 4 samples of which gave U-Pb SHRIMP ages between 705 and 718 Ma. Whole-rock geochemical data confirm the calc-alkaline, arc-related nature of the plutonic rocks. The volcanic rocks of the Daraina and Milanoa groups also

    2016-12-01

    At the start of the Quaternary, about 2.7 M yr ago, the bathymetry of the northern North Sea was dominated by the North Sea Basin, which has been infilled subsequently. The Norwegian Channel Ice Stream (NCIS) of the Scandinavian Ice Sheet (SIS) extended to the shelf break during several Mid to Late Quaternary full-glacial periods. However, little is known about Early Quaternary sedimentation on this margin. We use 2D and 3D seismic-reflection data to investigate the shelf and slope architecture and the patterns and processes of sedimentation in the northern North Sea through the Quaternary. The Early Quaternary infill of the northern North Sea Basin is shown to consist predominantly of glacigenic debris-flow deposits (GDFs) derived from an ice sheet that flowed perpendicular to the palaeo-shelf break during full-glacial periods, and contourites that were deposited by an ocean current that flowed parallel to the palaeo-shelf break during periods of reduced glaciation and active thermohaline circulation. This sequence of intercalated GDFs and contourites is suggested to record fluctuations in regional climate that are linked to the c. 41k glacial-interglacial cycles of the Early Quaternary. The Early Quaternary infilling of the northern North Sea Basin may have encouraged the initiation of a major ice stream by increasing the shelf width and reducing the water depth. Close to the onset of the Mid Quaternary, the south-western margin of the SIS was drained by an ice stream that was located partly beneath Måløy Plateau, 60 km east of the position of the NCIS during the Last Glacial Maximum. The changing architecture of the northern North Sea margin had an effect on the palaeo-oceanography of this region. The southward-flowing Norwegian Sea Bottom Water current is interpreted to have been directed into the concave, partially-closed northern North Sea Basin during the Early Quaternary, and to have been deflected progressively northwards as the basin became infilled.

  4. Impacts of Northern Pike on stocked Rainbow Trout in Pactola Reservoir, South Dakota

    Establishment of nonnative Northern Pike Esox lucius in Pactola Reservoir, South Dakota, has prompted concern among biologists about the influence of this species on the lake’s intensively managed salmonid fisheries. Ancedotal information suggests that catch rates of Rainbow Trout Oncorhynchus mykiss have declined while mean size and abundance of Northern Pike has increased, although quantitative information on diet and growth of the Northern Pike population is lacking. To address potential interactions between Northern Pike and Rainbow Trout, we assessed size-dependent predation by Northern Pike on Rainbow Trout and determined the relative energetic contribution of stocked Rainbow Trout to Northern Pike growth using bioenergetics modeling. Stable isotopes combined with traditional diet analyses revealed that smaller Northern Pike (accounted for 56% of their annual energy consumption. Combining estimates of Northern Pike predation with production costs of catchable-size Rainbow Trout revealed that annual economic losses ranged from US$15,259 to $24,801 per year. Over its lifespan, an age-10 Northern Pike was estimated to consume ~117 Rainbow Trout worth approximately $340. Thus, Northern Pike predation substantially influences salmonid management initiatives and is likely a primary factor contributing to reduced Rainbow Trout abundance and return to anglers in Pactola Reservoir. Strategies for reducing Northern Pike predation on Rainbow Trout include increasing the size of stocked fish or altering the timing and spatial distribution of stocking events.

    Echimyidae (spiny rats, tree rats and the coypu) is the most diverse family of extant South American hystricognath rodents (caviomorphs). Today, they live in tropical forests (Amazonian, coastal and Andean forests), occasionally in more open xeric habitats in the Cerrado and Caatinga of northern South America, and open areas across the southern portion of the continent (Myocastor). The Quaternary fossil record of this family remains poorly studied. Here, we describe the fossil echimyids found in karst deposits from southern Tocantins, northern Brazil. The analyzed specimens are assigned to Thrichomys sp., Makalata cf. didelphoides and Proechimys sp. This is the first time that a fossil of Makalata is reported. The Pleistocene record of echimyids from this area is represented by fragmentary remains, which hinders their determination at specific levels. The data reported here contributes to the understanding of the ancient diversity of rodents of this region, evidenced until now in other groups, such as the artiodactyls, cingulates, carnivores, marsupials, and squamate reptiles.

    This presentation described the Northern Lights Project and addressed the unique characteristics of oil sands which have led to innovative mine and extraction techniques. A table indicating the mining projects in development was presented with reference to recoverable bitumen and ore grade. The marketing aspects of synthetic crude that influence the choice of bitumen upgrader design and economics were discussed. It was noted that new pipeline developments should open up new market opportunities. The expected market for Synenco crude is the northern portion of the United States Midwest. There may also be a possibility to sell the product as diluent because Synenco crude has a lower vacuum gas oil (VGO) content and more naphtha than other synthetic crude. The properties of Synenco crude components were listed with reference to gravity, density, sulfur content, cetane number, smoke point, and feed quality. The trade-off between capital costs, operating cost and risk mitigation was also examined. tabs., figs

    Earthquake prediction study is carried out for the region of northern Pakistan. The prediction methodology includes interdisciplinary interaction of seismology and computational intelligence. Eight seismic parameters are computed based upon the past earthquakes. Predictive ability of these eight seismic parameters is evaluated in terms of information gain, which leads to the selection of six parameters to be used in prediction. Multiple computationally intelligent models have been developed for earthquake prediction using selected seismic parameters. These models include feed-forward neural network, recurrent neural network, random forest, multi layer perceptron, radial basis neural network, and support vector machine. The performance of every prediction model is evaluated and McNemar's statistical test is applied to observe the statistical significance of computational methodologies. Feed-forward neural network shows statistically significant predictions along with accuracy of 75% and positive predictive value of 78% in context of northern Pakistan.

    The Late Silurian is generally considered to a particular significant key period in the study of early land vascular plants. A trilete spore assemblage of the Upper Silurian is described from northern Jiangsu, China. This assemblage comprises 11 genera and 20 species of trilete spores (including laevigate, apiculate, perinotrilite, patinate, rarely distally murornate and equatorially crassitate, and three indeterminate trilete miospores forms). It has similarities to those described from coeval assemblages from around the world (e.g., England and South Wales; Tripolitania, Libya; Cornwallis Island, Canadian Arctic; Northwest Spain). The rare cryptospore, only one specimen (Tetrahedraletes sp.) had been found to be associated with the Chinese trilete spore assemblage. The discovery of the trilete spores from Late Silurian rocks indicates the existence of early land plants, some possibly vascular, at that time in northern Jiangsu, China.

  10. History of Taenia saginata Tapeworms in Northern Russia

    Science.gov (United States)

    Konyaev, Sergey V.; Nakao, Minoru; Ito, Akira

    2017-01-01

    Taenia saginata is the most common species of tapeworm infecting humans. Infection is acquired by eating cysticercus larvae in undercooked beef. A closely related species, T. asiatica, is found in eastern and southeastern Asia. The larvae of T. asiatica develop in viscera of pigs. In northern Russia, there is a third member of this morphologically indistinguishable group. Cysticerci of so-called northern T. saginata are found in cerebral meninges of reindeer, and the unique life cycle is dependent on a native custom of eating raw reindeer brain. We report the winding history of this mysterious tapeworm from the first reports to the present time. In addition, we confirm the position of this parasite as a strain of T. saginata by analyzing a mitochondrial DNA sequence of an archival specimen. The origin of this strain might date back to reindeer domestication and contacts between cattle-herding and reindeer-herding peoples in Asia.

    Full Text Available This paper focuses on two groups of sub-ethnic Chinese children respectively migrating from Mainland China and Hong Kong to Northern Ireland. It examines their cultural narratives surrounding topics of their country of origin, their adopted society in Northern Ireland. The paper analyses not only the surface narratives themselves, but also the social, cultural and political context in which such dispositional narratives were nourished and made possible. Theoretically, the author uses BOURDIEU's concept of "habitus" as the analytical tool to interpret and explain such narrative dispositions. Methodologically, the author uses in-depth interviewing and observations to achieve a more objective and overall understanding of their cultural narratives. URN: urn:nbn:de:0114-fqs0604297

    2013-01-01

    Climate change in the Arctic is a growing concern for natural resource conservation and management as a result of accelerated warming and associated shifts in the distribution and abundance of northern species. We introduce a predictive framework for assessing the future extent of Arctic tundra and boreal biomes in northern Alaska. We use geo-referenced museum specimens to predict the velocity of distributional change into the next century and compare predicted tundra refugial areas with current land-use. The reliability of predicted distributions, including differences between fundamental and realized niches, for two groups of species is strengthened by fossils and genetic signatures of demographic shifts. Evolutionary responses to environmental change through the late Quaternary are generally consistent with past distribution models. Predicted future refugia overlap managed areas and indicate potential hotspots for tundra diversity. To effectively assess future refugia, variable responses among closely related species to climate change warrants careful consideration of both evolutionary and ecological histories.

  13. Northern Ireland in Transition: The Role of Justice

    Directory of Open Access Journals (Sweden)

    2005-03-01

    Full Text Available All post-conflict societies switching to constitutional liberal democracies have to deal with their past through transitional justice mechanisms that offer to hear the victims, try the perpetrators of all types of abuses, introduce peace and reconciliation schemes. It is time for state and non-state organs to account for past crimes. Several countries have successfully tested such mechanisms. Northern Ireland is the ideal ground for transitional justice to operate but it dispels foreign tailor-made models. However, a number of major reforms and projects have addressed sensitive issues in the wake of the Good Friday Agreement. Two key institutions, the police and the criminal justice system, whose responsibility in the conflict was undeniable, have been reformed. Law and lawyers are concerned with these changes and the introduction of a Human Rights culture in Northern Ireland. A clear break with the past must be achieved for transitional justice mechanisms to work successfully.

  14. Comparative reproductive and physiological responses of northern bobwhite and scaled quail to water deprivation

    1998-01-01

    We compared reproductive and physiological responses of captive female northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) under control and water deprivation conditions. Scaled quail required less food and water to reproduce successfully under control conditions than northern bobwhite. Additionally, in scaled quail, serum osmolality levels and kidney mass were unaffected by water deprivation, whereas in northern bobwhite, serum osmolality levels increased and kidney mass declined. This finding indicates that scaled quail may have osmoregulatory abilities superior to those of northern bobwhite. Under control conditions, northern bobwhite gained more body mass and produced more but smaller eggs than scaled quail. Under water deprivation conditions, northern bobwhite lost more body mass but had more laying hens with a higher rate of egg production than scaled quail. Our data suggest that northern bobwhite allocated more resources to reproduction than to body maintenance, while scaled quail apparently forego reproduction in favor of body maintenance during water deprivation conditions.

    2013-01-01

    In recent years stock structure recommendations for megrim on the Northern Shelf have varied, primarily due to a lack of biological and fishery data. In this study, we compared a number of life history characteristics of the common megrim Lepidorhombus whiffiagonis (Walbaum) between the northern North Sea and Rockall, the latitudinal extremes of the species' distribution on the Northern Shelf. Reproductive timing, sex ratio, maturity and growth were different between the two study areas. Reproductive timing in the northern North Sea was more protracted than at Rockall and other areas. There were differences in sex ratio between the study areas and female megrim in the northern North Sea exhibited different growth rates and larger size at maturity than at Rockall. The results of this study support the recent changes to the definition of the Northern Shelf stocks which recommend that the northern North Sea be treated separately to Rockall.

  17. Stratospheric influence on Northern Hemisphere winter climate variability

    Science.gov (United States)

    Ouzeau, Gaelle; Douville, Herve; Saint Martin, David

    2010-05-01

    Despite significant improvements in observing and data assimilation systems, long-range dynamical forecasting remains a difficult challenge for the climate modelling community. The skill of operational seasonal forecasting systems is particularly poor in the northern extratropics where seas surface temperature (SST) has a weaker influence than in the Tropics. It is therefore relevant to look for additional potential sources of long-range climate predictability in the stratosphere using ensembles of global atmospheric simulations. Besides a control experiment where the ARPEGE-Climat model is only driven by SST, parallel simulations have been performed in which an additional control on climate variability has been accounted for through the nudging of the northern extratropical stratosphere towards the ERA40 reanalysis. Though idealized, this original experiment design allows us to compare the relative contribution of the lower and upper boundary forcings on the simulated tropospheric variability. Results show that the stratospheric nudging improves the climatology and interannual variability of the mid-latitude troposphere, especially in winter in the Northern Hemisphere. Major impacts are found in particular on the simulation of the Arctic and North Atlantic oscillations (AO and NAO). Case studies were carried out for the 1976-1977 and 1988-1989 winters, corresponding to extreme phases of the AO. Results confirm the robustness of the positive impact of the nudging, especially for winter 1976-1977 corresponding to relatively weak SST anomalies in the tropical Pacific. A sensitivity study to the model resolution shows that a well-resolved stratosphere is not necessary for the nudging to be efficient. Besides seasonal mean results, analysis of the day-to-day variability in winter allowed us to better understand the stratospheric polar vortex influence on the tropospheric circulation in the Northern Hemisphere mid-latitudes.

  8. Rural electrification: Waste biomass Russian northern territories. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Adamian, S. [ECOTRADE, Inc., Glendale, CA (United States)

    1998-02-01

    The primary objective of this pre-feasibility evaluation is to examine the economic and technical feasibility of replacing distillate fuel with local waste biomass in the village of Verkhni-Ozerski, Arkhangelsk Region, Russia. This village is evaluated as a pilot location representing the off-grid villages in the Russian Northern Territories. The U.S. Department of Energy (DOE) has agreed to provide technical assistance to the Ministry of Fuel and Energy (MFE). MFE has identified the Northern Territories as a priority area requiring NREL`s assistance. The program initially affects about 900 off-grid villages. Biomass and wind energy, and to a lesser extent small hydro (depending on resource availability) are expected to play the dominant role in the program, Geothermal energy may also have a role in the Russian Far East. The Arkhangelsk, Kariela, and Krasnoyarsk Regions, all in the Russian Northern Territories, have abundant forest resources and forest products industries, making them strong candidates for implementation of small-scale waste biomass-to-energy projects. The 900 or so villages included in the renewable energy program span nine administrative regions and autonomous republics. The regional authorities in the Northern Territories proposed these villages to MFE for consideration in the renewable energy program according to the following selection criteria: (a) Remote off-grid location, (b) high cost of transporting fuel, old age of existing power generation equipment, and (d) preliminary determination as to availability of alternative energy resources. Inclusion of indigenous minorities in the program was also heavily emphasized. The prefeasibility study demonstrates that the project merits continuation and a full feasibility analysis. The demonstrated rate of return and net positive cash flow, the willingness of Onegales and local/regional authorities to cooperate, and the immense social benefits are all good reasons to continue the project.

    Tourist numbers in northern Fennoscandia outweigh those in other northern boreal - arctic regions, which creates a specific need to evaluate the impacts of tourism. This review 1) identifies patterns and trends in the vegetation and wildlife of northern Fennoscandian terrestrial ecosystems as a consequence of tourism and recreation, 2) discusses the implications of findings in terms of the intensity, area and magnitude of impacts, changing climate and management needs under increasing tourist pressure, and 3) identifies research gaps. The reviewed studies show negative environmental and biodiversity impacts that are most pronounced near tourist resorts. The most sensitive plants, birds and mammals decline or disappear from the disturbed sites, and the species composition shifts from 'wild' species to cultural and human associated species. There is little research on the spread of alien species, but the few examples show that alien species can be promoted by tourism activities. Impacts of the use of motorized vehicles have not been widely studied either, despite the extensive track network which can cause disturbance to wildlife. The integrated impacts of tourism and climate change on the vegetation and wildlife was not addressed directly in any of the reviewed studies. In addition, little research has been done on carrying out restoration at tourist areas. Scientific research on these topics is needed to prevent, minimize or restore the most negative ecological impacts of tourism and recreation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The Northern Great Plains is the bread basket of the United States, accounting for a substantial portion of U.S. agricultural production. This region faces critical challenges regarding balancing food needs, resource conservation (e.g Ogallala aquifer), environmental concerns, and rural economy development. Developing transformative, multifunctional systems will require equally imaginative and efficient tools to help farmers manage complex agroecosystems in a rapidly changing climate. The Northern Plains long-term agroecosystem research (LTAR) site at Mandan, ND and the Platte River High Plains LTAR (ARS/University of Nebraska-Lincoln) at Lincoln, NE in collaboration with USDA-ARS research units in Brookings, SD and Fargo, ND are collaborating to address the grand challenge of providing and sustaining multiple service provisions from Northern Great Plains agroecosystems. We propose to attain these goals through sustainable intensification based on the adoption of conservation agriculture principles including reduced soil disturbance, livestock integration, and greater complexity and diversity in the cropping system. Here, we summarize new concepts these locations have pioneered in dynamic cropping systems, resource use efficiency, and agricultural management technologies. As part of the LTAR network, we will conduct long-term cross-site research to design and assess new agricultural practices and systems aimed at improving our understanding of decision making processes and outcomes across an array of agricultural systems.

    Postpartum cultural beliefs and practices are widely prevalent in northern Nigeria. Using a cross-sectional survey, we set out to examine contemporary postpartum beliefs and practices among a cohort of 300 mothers in Danbare village, northern Nigeria. Common postpartum practices included sexual abstinence (100%), physical confinement (88%), hot ritual baths (86%), nursing in heated rooms (84%) and ingestion of gruel enriched with local salt (83%). The majority of mothers (93%) believed that these practices made them stronger and helped them regain their physiologic state. Most respondents believed that non-observance could lead to body swelling, foul-smelling lochia and perineal pain. Mothers with formal education were significantly more likely to believe that these practices were non-beneficial compared with those mothers without formal education (odds ratio (OR) = 9.9, 95% confidence interval (CI) = 3.6 - 28.8). Almost half of the respondents (49%) said they would continue with these practices. In conclusion, women are still holding on to postpartum cultural beliefs and practices in northern Nigeria. However, educated women could act as useful agents of change towards the elimination of practices harmful to the health of mothers and their children.

    Global climate changes sometimes spark biological radiations that can feed back to effect significant ecological impacts. Northern Hemisphere peatlands dominated by living and dead peatmosses (Sphagnum) harbor almost 30% of the global soil carbon pool and have functioned as a net carbon sink throughout the Holocene, and probably since the late Tertiary. Before that time, northern latitudes were dominated by tropical and temperate plant groups and ecosystems. Phylogenetic analyses of mosses (phylum Bryophyta) based on nucleotide sequences from the plastid, mitochondrial, and nuclear genomes indicate that most species of Sphagnum are of recent origin (ca. Sphagnum species are not only well-adapted to boreal peatlands, they create the conditions that promote development of peatlands. The recent radiation that gave rise to extant diversity of peatmosses is temporally associated with Miocene climatic cooling in the Northern Hemisphere. The evolution of Sphagnum has had profound influences on global biogeochemistry because of the unique biochemical, physiological, and morphological features of these plants, both while alive and after death. 2010 Elsevier Inc.

    The Northern River Basins Human Health Monitoring Program was established in 1994 to investigate the possible relationships between various environmental risk factors and the health of northern residents in the province. This report presents the initial analysis of the health program and examines the differences in health outcomes across the province and compares the Northern Rivers Basin Study (NRBS) area with the other areas of the province. A series of maps and graphs showed the prevalence of certain diseases and disorders within the Peace and Athabasca river basins. The focus of the report was on reproductive health, congenital anomalies, respiratory ailments, circulatory diseases, gastrointestinal disorders, endocrine and metabolic disorders, and neurocognitive disorders. The study showed that compared to other areas of the province, the NRBS area had higher incidences of endometriosis, selected congenital anomalies, bronchitis, pneumonia, peptic ulcers and epilepsy. There were three potential exposure pathways to environmental contaminants. These were through ingestion of water or food, inhalation of air and through dermal exposure. refs., tabs., figs.

    To develop prediction equations for spirometry for children from northern India using current international guidelines for standardization. Re-analysis of cross-sectional data from a single school. 670 normal children (age 6-17 y; 365 boys) of northern Indian parentage. After screening for normal health, we carried out spirometry with recommended quality assurance according to current guidelines. We developed linear and nonlinear prediction equations using multiple regression analysis. We selected the final models on the basis of the highest coefficient of multiple determination (R2) and statistical validity. Spirometry parameters: FVC, FEV1, PEFR, FEF50, FEF75 and FEF25-75. The equations for the main parameters were as follows: Boys, Ln FVC = -1.687+0.016*height +0.022*age; Ln FEV1 = -1.748+0.015*height+0.031*age. Girls, Ln FVC = -9.989 +(2.018*Ln(height)) + (0.324*Ln(age)); Ln FEV1 = -10.055 +(1.990*Ln(height))+(0.358*Ln(age)). Nonlinear regression yielded substantially greater R2 values compared to linear models except for FEF50 for girls. Height and age were found to be the significant explanatory variables for all parameters on multiple regression with weight making no significant contribution. We developed prediction equations for spirometry for children from northern India. Nonlinear equations were superior to linear equations.

    The history of hydroelectric development in northern Ontario was reviewed and analysed with special emphasis on the developments along the Mattagami and Abitibi Rivers. The objective was to examine the important factors that shaped modern hydroelectric development in Canada. System builders, the privately owned Nesbitt Thomson Company, the publicly owned Hydro Electric Power Corporation of Ontario and the eventual evolution of the single power system under Ontario Hydro are chronicled. Broad historical themes such as the technological impacts, regionalism, indigenous rights, plus environmental and economic issues are examined, in addition to an appreciation of the importance of electricity in the manufacturing sector of Ontario, the impact of hydroelectric development on the northern environment and on the northern First Nations, who rely on rivers for their subsistence. Until fairly recently, government policies and interpretations of law often excluded the recognition of Aboriginal uses of river systems, thereby limiting First Nations' peoples ability to practice traditional ways of life. In essence, the book is an account of how the northeastern power system in Ontario shaped the social, political and natural environments and how the development of northeastern power sources by southern power developers shaped the regional interactions between Ontario's north and south. refs., figs

  17. Correlation of Crustal Structures and Seismicity Patterns in Northern Appalachians

    The earthquake distributions in northern Appalachians are bounded by major geologically-defined terrane boundaries. There is a distinct seismic gap within Taconic Belt between the Western Quebec Seismic Zone (WQSZ) to the west and the seismically active Ganderia terrane to the east. It is not clear, however, what crustal structures control the characteristics of earthquake clustering in this region. Here we present a newly constructed crustal shear velocity model for the northern Appalachians using Rayleigh wave data extracted from ambient noises. Our tomographic model reveals strongly heterogeneous seismic structures in the crust. We observe multiple NW-dipping patches of high-velocity anomalies in the upper crust beneath the southeastern WQSZ. The upper crust shear velocities in the Ganderia and Avalonia region are generally lower than those beneath the WQSZ. The middle crust has relatively lower velocities in the study area. The earthquakes in the study area are constrained within the upper crust. Most of the earthquake hypocenters within the WQSZ are concentrated along the NW-dipping boundaries separating the high-velocity anomalies. In contrast, most of the earthquake hypocenters in the Ganderia and Avalonia region are diffusely distributed without clear vertical lineaments. The orientations of maximum compressive stresses change from W-E in the Ganderia and Avalonia region to SW-NE in the WQSZ. The contrasts in seismicity, velocity, and stress field across the Taconic Belt indicate that the Taconic Belt terrane may act as a seismically inactive buffer zone in northern Appalachians.

    A survey was carried out in Northern Nigeria to determine the distribution of the species of phlebotomine sandflies in the major vegetation zones: Sahel, Sudan, Northern Guinea Savanna, and Southern Guinea Savanna. The two Old World Genera, Phlebotomus and Sergentomyia, are both represented in the study area, with an overwhelming preponderance of Sergentomyia species; about 99% of the entire collection (12, 951 specimens) belong to the genus Sergentomyia. Out of the thirteen species identified, two belong to the genus Phlebotomus: Phlebotomus duboscqi and Phlebotomus rodhaini; the remaining eleven are species of the genus Sergentomyia grouped under series simillama and two subgenera (antennata, bedfordi, africana, schwetzi, ingrami, and buxtoni in the subgenus Sergentomyia and affinis, adleri, clydei and christophersi under Sintonius subgenus. P. duboscqi occurs in Sahel and Sudan zones whereas P. rodhaini exists mainly in the Guinea Savanna (north and south). In general, the distribution of the species in the subgenus Sergentomyia (particularly antennatta, bedfordi, africana, and schwetzi) cuts across all the four vegetation zones. The least common species, simillima, was found only in the North Guinea Savanna. Members of the Sintonius group were obtained from Sudan and Northern Guinea Savanna zones.

    The area and elevation of the Tibetan Plateau over time has directly affected Asia's topography, the characteristics of the Asian monsoon, and modified global climate, but in ways that are poorly understood. Charting the uplift history is crucial for understanding the mechanisms that link elevation and climate irrespective of time and place. While some palaeoelevation data are available for southern and central Tibet, clues to the uplift history of northern Tibet remain sparse and largely circumstantial. Leaf fossils are extremely rare in Tibet but here we report a newly discovered early Miocene barberry (Berberis) from Wudaoliang in the Hoh-Xil Basin in northern Tibet, at a present altitude of 4611 ± 9 m. Considering the fossil and its nearest living species probably occupied a similar or identical environmental niche, the palaeoelevation of the fossil locality, corrected for Miocene global temperature difference, is estimated to have been between 1395 and 2931 m, which means this basin has been uplifted ~2-3 km in the last 17 million years. Our findings contradict hypotheses that suggest northern Tibet had reached or exceeded its present elevation prior to the Miocene.

    The growth potential of Muskellunge Esox masquinongy was evaluated by back-calculating growth histories from cleithra removed from 305 fish collected during 1995–2011 to determine whether it was consistent with trophy management goals in northern Wisconsin. Female Muskellunge had a larger mean asymptotic length (49.8 in) than did males (43.4 in). Minimum ultimate size of female Muskellunge (45.0 in) equaled the 45.0-in minimum length limit, but was less than the 50.0-in minimum length limit used on Wisconsin's trophy waters, while the minimum ultimate size of male Muskellunge (34.0 in) was less than the statewide minimum length limit. Minimum reproductive sizes for both sexes were less than Wisconsin's trophy minimum length limits. Mean growth potential of female Muskellunge in northern Wisconsin appears to be sufficient for meeting trophy management objectives and angler expectations. Muskellunge in northern Wisconsin had similar growth potential to those in Ontario populations, but lower growth potential than Minnesota's populations, perhaps because of genetic and environmental differences.
