    1983-12-01

    This report summarizes the regional geologic and environmental characterizations that have been completed for the Permian region of study, and describes the procedure used to identify study areas for the next phase of investigation. The factors evaluated in the Permian region fall into three broad areas: health and safety, environmental and socioeconomic, and engineering and economic considerations. Health and safety considerations included salt depth and thickness, faults, seismic activity, groundwater, salt dissolution, energy and mineral resources, presence of boreholes, and interactive land uses. Salt depth and thickness was the key health and safety factor, and when mapped, provded to be a discriminator. The evaluation of environmental and socioeconomic conditions focused primarily on the presence of urban areas and on designated land uses such as parks, wildlife areas, and historic sites. Engineering and economic considerations centered primarily on salt depth, which was already evaluated in the health and safety area. The Palo Duro and Dalhart basins are recommended for future studies on the basis of geology. In these two basins, salt depth and thickness appear promising, and there is less likelihood of past or future oil and gas exploratory holes. Environmental and socioeconomic factors did not preclude any of the basins from further study. 66 references, 16 figures, 2 tables

    The rapid industrial development and urbanization processes that occurred in China over the past 30years has increased dramatically the consumption of natural resources and raw materials, thus exacerbating the human pressure on environmental ecosystems. In result, large scale environmental pollution of soil, natural waters and urban air were recorded. The development of effective industrial planning to support regional sustainable economy development has become an issue of serious concern for local authorities which need to select safe sites for new industrial settlements (i.e. industrial plants) according to assessment approaches considering cumulative impacts, synergistic pollution effects and risks of accidental releases. In order to support decision makers in the development of efficient and effective regional land-use plans encompassing the identification of suitable areas for new industrial settlements and areas in need of intervention measures, this study provides a spatial regional risk assessment methodology which integrates relative risk assessment (RRA) and socio-economic assessment (SEA) and makes use of spatial analysis (GIS) methodologies and multicriteria decision analysis (MCDA) techniques. The proposed methodology was applied to the Chinese region of Hulunbeier which is located in eastern Inner Mongolia Autonomous Region, adjacent to the Republic of Mongolia. The application results demonstrated the effectiveness of the proposed methodology in the identification of the most hazardous and risky industrial settlements, the most vulnerable regional receptors and the regional districts which resulted to be the most relevant for intervention measures since they are characterized by high regional risk and excellent socio-economic development conditions.

    International Nuclear Information System (INIS)

    1984-12-01

    Surface landforms in the Salt Valley Area are generally a function of the Salt Valley anticline and are characterized by parallel and subparallel cuestaform ridges and hogbacks and flat valley floors. The most prominent structure in the Area is the Salt Valley anticline. Erosion resulting from the Tertiary uplift of the Colorado Plateau led to salt dissolution and subsequent collapse along the crest of the anticline. Continued erosion removed the collapse material, forming an axial valley along the crest of the anticline. Paleozoic rocks beneath the salt bearing Paradox Formation consist of limestone, dolomite, sandstone, siltstone and shale. The salt beds of the Paradox Formation occur in distinct cycles separated by an interbed sequence of anhydrite, carbonate, and clastic rocks. The Paradox Formation is overlain by Pennsylvanian limestone; Permian sandstone; and Mesozoic sandstone, mudstone, conglomerate and shale. No earthquakes have been reported in the Area during the period of the historic record and contemporary seismicity appears to be diffusely distributed, of low level and small magnitude. The upper unit includes the Permian strata and upper Honaker Trail Formation. The current data base is insufficient to estimate ground-water flow rates and directions in this unit. The middle unit includes the evaporites in the Paradox Formation and no laterally extensive flow systems are apparent. The lower unit consists of the rocks below the Paradox Formation where permeabilities vary widely, and the apparent flow direction is toward the west. 108 refs., 39 figs., 9 tabs

    In recent years, monitoring vegetation biomass over various climate zones has become the primary focus of several studies interested in assessing the role of the ecosystem responses to climate change and human activities. Airborne and spaceborne Synthetic Aperture Radar (SAR) systems provide a useful tool to directly estimate biomass due to its sensitivity to structural and moisture characteristics of vegetation canopies. Even though the sensitivity of SAR data to total aboveground biomass has been successfully demonstrated in many controlled experiments over boreal forests and forest plantations, so far, no biomass estimation algorithm has been developed. This is mainly due to the fact that the SAR data, even at lowest frequency (P-band) saturates at biomass levels of about 200 tons/ha, and the structure and moisture information in the SAR signal forces the estimation algorithm to be forest type dependent. In this paper, we discuss the development of a hybrid forest biomass algorithm which uses a SAR derived land cover map in conjunction with a forest backscatter model and an inversion algorithm to estimate forest canopy water content. It is shown that unlike the direct biomass estimation from SAR data, the estimation of water content does not depend on the seasonal and/or environmental conditions. The total aboveground biomass can then be derived from canopy water content for each type of forest by incorporating other ecological information. Preliminary results from this technique over several boreal forest stands indicate that (1) the forest biomass can be estimated with reasonable accuracy, and (2) the saturation level of the SAR signal can be enhanced by separating the crown and trunk biomass in the inversion algorithm. We have used the JPL AIRSAR data over BOREAS southern study area to test the algorithm and to generate regional scale water content and biomass maps. The results are compared with ground data and the sources of errors are discussed. Several SAR

    The Paradox Basin was re-evaluated to determine if any parts of the Basin that had not been identified in previous studies might be suitable for a more detailed evaluation as a nuclear waste repository site. The factors used in this re-evaluation were depth to salt and dedicated lands, because these factors directly address the engineering and environmental feasibility of a repository. Six areas (Happy Canyon, Green River, Dolores River, Expectation Mountain, Dark Canyon, and Kane Springs Canyon) were identified on this basis as potentially suitable areas for further study. These areas were assessed in more detail to review the feasibility of siting a repository. None of the six areas was recommended for further study as a repository site because the size of the areas, thickness of the salt beds, topography, and engineering factors resulting from the loading of nearby mesas generally did not allow the construction of a feasible repository. The content of this report was effective as of May 1983. 41 references, 17 figures

    Remote sensing technology is of significant advantages for monitoring and analysing ecological environment. By using of automatic extraction algorithm, various environmental resources information of tourist region can be obtained from remote sensing imagery. Combining with GIS spatial analysis and landscape pattern analysis, relevant environmental information can be quantitatively analysed and interpreted. In this study, taking the Chaohu Lake Basin as an example, Landsat-8 multi-spectral satellite image of October 2015 was applied. Integrated the automatic ELM (Extreme Learning Machine) classification results with the data of digital elevation model and slope information, human disturbance degree, land use degree, primary productivity, landscape evenness , vegetation coverage, DEM, slope and normalized water body index were used as the evaluation factors to construct the eco-sensitivity evaluation index based on AHP and overlay analysis. According to the value of eco-sensitivity evaluation index, by using of GIS technique of equal interval reclassification, the Chaohu Lake area was divided into four grades: very sensitive area, sensitive area, sub-sensitive areas and insensitive areas. The results of the eco-sensitivity analysis shows: the area of the very sensitive area was 4577.4378 km2, accounting for about 37.12 %, the sensitive area was 5130.0522 km2, accounting for about 37.12 %; the area of sub-sensitive area was 3729.9312 km2, accounting for 26.99 %; the area of insensitive area was 382.4399 km2, accounting for about 2.77 %. At the same time, it has been found that there were spatial differences in ecological sensitivity of the Chaohu Lake basin. The most sensitive areas were mainly located in the areas with high elevation and large terrain gradient. Insensitive areas were mainly distributed in slope of the slow platform area; the sensitive areas and the sub-sensitive areas were mainly agricultural land and woodland.

The method used in this study offers great potential for lithological mapping, by using Sentinel-2 imagery, the results were compared with existing geologic maps and were superior and could be used to update the existing maps.

  20. A regional study of the radiation environment of Greenham Common, Newbury District and surrounding areas

    International Nuclear Information System (INIS)

    1997-02-01

    This study was commissioned by Newbury District Council and Basingstoke and Deane Borough Council in response to public concern following disclosures about events at Greenham Common in the 1950s, and the suspicion that there may have been an accident involving a nuclear weapon leading to off-site contamination at the airbase. The Greenham Common airbase is at an advanced stage of decommissioning with parts of the site already re-developed for industrial and leisure purposes and material being removed for use in construction of the Newbury by-pass. The success of such developments is critically dependent on public confidence in the quality of the environment, both near the site, and more generally throughout the area. For this reason the study was commissioned with the aims of: I. defining the radiation environment of the whole district and parts of its surrounding areas. II. examining whether there is any evidence of radioactive contamination in the vicinity of the Greenham Common airbase. III. assessing the evidence that there may have been a release of nuclear material from the site. The work involved a collaboration between scientists from the Scottish Universities Research and Reactor Centre, who conducted gamma ray surveys to define the general radiation environment of the area, and Scientists from the University of Southampton who collected an extensive range of samples for high sensitivity radiochemical analyses. This report presents their findings and main conclusions, together with a discussion of the background to the study and its implications. (Author)

    "Surplus income" of farmers has been increasing steadily with the marked improvement of rural economy. However,development of rural financing market in China is rather backward. To satisfy the financing requirement of farmers and meet the demand of the construction of new countryside as well as harmonious society,development of financing market in rural area is eager to be quickened. Taking Guangxi Autonomous Region as an example,there are problems in rural investing and financing development. Firstly,farmers are in lacking of accurate understanding of investing and financing. Secondly,investors in rural area lack professional knowledge about financing generally. Thirdly,rural area has underdeveloped information degree as well as imperfect investing and financing environment. Fourthly,there are no financial products developed for rural area. Fifthly,economic development is unbalanced and relatively underdeveloped in rural area. Lastly,rural financial market has long been neglected by financial intermediaries. In order to cope with these problems,firstly,farmers should be assisted to establish accurate financial awareness and master necessary financial knowledge. Secondly,local intermediaries like securities firms and banks should be encouraged to exert impact on rural financial market. Thirdly,financial products suitable for Guangxi rural area are to be developed. Fourthly, construction and perfection of rural financial market should be quickened. Lastly,rural economic development should be quickened to enlarge capital source of financing.

    To investigate if protracted living in degraded environments of the Caserta and Naples provinces (Campania Region, Italy) had an impact on exposure of local people, highly toxic persistent contaminants were measured in blood, blood serum, and human milk of a large number of healthy donors. Sampling was carried out from 2008 to 2009. Blood was collected from over 850 20–64-year old donors; by pooling, 84 blood and 84 serum samples were obtained. Milk was donated by 52 mothers: specimens were pooled into six samples. Polychlorodibenzodioxins (PCDDs), polychlorodibenzofurans (PCDFs), and polychlorobiphenyls (PCBs, dioxin-like (DL) and non-dioxin-like (Σ 6 PCBs)), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) were measured in serum (organic biomarkers) and blood (metals); these chemicals and polybromobiphenyl ethers (Σ 9 PBDEs) were analyzed in milk. PCDD + PCDF, DL-PCB, TEQ TOT , and Σ 6 PCB concentration ranges (medians) in serum were 6.26–23.1 (12.4), 3.42–31.7 (11.5), 10.0–52.8 (23.9) pgTEQ 97 /g fat, and 55.5–647 (219) ng/g fat, respectively, while in milk concentration ranges were 5.99–8.77, 4.02–6.15, 10.0–14.2 pgTEQ 97 /g fat, and 48.7–74.2 ng/g fat. Likewise, As, Cd, Hg, and Pb findings in blood spanned 2.34–13.4 (5.83), 0.180–0.930 (0.475), 1.09–7.60 (2.60), 10.2–55.9 (28.8) μg/L, respectively; only Pb could be measured in milk (2.78–5.99 μg/L). Σ 9 PBDE levels in milk samples were 0.965–6.05 ng/g fat. Biomarkers' concentrations were found to be compatible with their current values in European countries and in Italy, and consistent with an exposure primarily determined by consumption of commercial food from the large distribution system. Based on relatively higher biomarker values within the hematic biomonitoring database, the following municipalities were flagged as possibly deserving attention for health-oriented interventions: Brusciano and Caivano (As), Giugliano (Hg), Pianura (PCDDs + PCDFs), and Qualiano

    To investigate if protracted living in degraded environments of the Caserta and Naples provinces (Campania Region, Italy) had an impact on exposure of local people, highly toxic persistent contaminants were measured in blood, blood serum, and human milk of a large number of healthy donors. Sampling was carried out from 2008 to 2009. Blood was collected from over 850 20–64-year old donors; by pooling, 84 blood and 84 serum samples were obtained. Milk was donated by 52 mothers: specimens were pooled into six samples. Polychlorodibenzodioxins (PCDDs), polychlorodibenzofurans (PCDFs), and polychlorobiphenyls (PCBs, dioxin-like (DL) and non-dioxin-like (Σ{sub 6}PCBs)), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) were measured in serum (organic biomarkers) and blood (metals); these chemicals and polybromobiphenyl ethers (Σ{sub 9}PBDEs) were analyzed in milk. PCDD + PCDF, DL-PCB, TEQ{sub TOT}, and Σ{sub 6}PCB concentration ranges (medians) in serum were 6.26–23.1 (12.4), 3.42–31.7 (11.5), 10.0–52.8 (23.9) pgTEQ{sub 97}/g fat, and 55.5–647 (219) ng/g fat, respectively, while in milk concentration ranges were 5.99–8.77, 4.02–6.15, 10.0–14.2 pgTEQ{sub 97}/g fat, and 48.7–74.2 ng/g fat.

    Morphofunctional liver state of two mice-like rodents species caught at the three areas of Altai region exposed to radiation during nuclear tests at Semipalatinsk site was studied. It was shown that the stereotype morphofunctional changes in the liver of both rodent species were developed under chronical influence of low doses of radiation and chemical contamination. These changes are manifested as dystrophic disorders of hepatocytes and hemodynamic disturbances accompanied by a decrease of volume ratio of sinusoidal capillaries to hepatocytes and stroma to parenchyma. Hyperglicogenosis, redistribution of the main cytoplasmic organelles, and considerably reduction of the volume densities of mitochondria, smooth and rough endoplasmic reticulum are the leading ultrastructural changes. Moreover, character and manifestation of the changes are determined by ecological belonging and correlated with intensity of anthropogenic pollution. The role of these changes in development of long term pathology are discussed

    Nuclear Medicine in Brazil and worldwide has developed distinction with diagnosis techniques that allow metabolic research of the disease, changing in a significant fashion the patient's outcome. This innovative technology leads expectations from specific fields up to society itself. This research studied the use of 18 F-FDG radiopharmaceutical in the metropolitan region of Sao Paulo and adjacent areas, as well as the recent trade structure and the difficulties that should be overcome with the increase of the 18 F-FDG demand. This research counted on the analysis of the international radiopharmaceutical trade and the main changes that have been happening in this area in Brazil during the past few years. Interviews were performed with professionals within the area of nuclear medicine and data has been collected through questionnaire sent to the consuming centers of the radiopharmaceutical in the region covered in this research. The interviews expressed the opinions of the interviewees concerning transformations in this field and future tendencies and the information obtained from the survey was the basis of complementation of the use of radiopharmaceutical on equipment such as Single Photon Emission Computed Tomography (SPECT), Positron Emission Tomography (PET) and Positron Emission Tomography I Computer Tomography (PET/CT). The major use of 18 F-FDG has been used for oncology diagnosis with equipment such as PET and PEC/CT. This use shall grow in the next years, maybe expanding to other specialties such as neurology and cardiology. Although nowadays restricted to the cities of Sao Paulo and Rio de Janeiro, there is a possibility of expansion to other diagnosis modalities in other states of the country that are starting to structure the production of the radioisotope. The recent change in the constitution permitting the production and commerce of short half-life radioisotopes also contributes to the increase the interest of private funding of this sector in which

    Regional collaboration has been identified as a potential facilitator of public health preparedness efforts. The Urban Area Security Initiative (UASI) grant program, administered by the Federal Emergency Management Agency (FEMA) since 2003, has provided 64 high-risk metropolitan areas funding to enhance their regional preparedness capabilities. This study describes informal and formal regional collaboration infrastructure, as well as regional collaboration–related activities and assessment methods, in FFY2010 UASI regions. A cross-sectional online survey was administered via Survey Monkey from September through December 2013. Points of contact from FFY2010 funded UASI metropolitan areas completed the survey, with a response rate of 77.8% (n=49). Summary statistics were calculated to describe the current informal and formal regional collaboration infrastructure. Additionally, the cross-sectional survey collected rates of agreement with 8 collaborative preparedness statements at 3 time points. The survey found that UASI regions are engaging in collaborative activities and investments to build capabilities, with most collaboration occurring in the prevention, protection, and response mission areas. Collaborative relationships in preparedness among emergency managers and municipal chief executive officers improved during the FFY2010 UASI performance period compared to the pre-UASI award period, with lasting effects. The majority of UASI regions reported conducting independent assessments of capabilities and their measurement at the UASI region level. Urban areas that received a FFY2010 UASI grant award are engaging in collaborative activities and have established interjurisdictional relationships in preparedness. The use of grant funds to encourage collaboration in preparedness has the potential to leverage limited resources and promote informed investments. PMID:25398073

    With appropriate controls, experimental groups of inbred C 3 H mice bearing a syngeneic mammary carcinoma challenge in their right rear footpads were injected in both rear footpads with 99 Tcsup(m)ASC. Mice were sacrificed 15 and 90 min after the labelled colloid injection. Popliteal and sacral lymph nodes were weighed and counted in a well scintillation counter. A marked inhibition of labelled colloid uptake was demonstrated in regional lymph nodes draining a tumour-bearing area. Rabbits bearing VX 2 carcinoma in a forelimb received 99 Tc sup(m)ASC into each front footpad. Depression of labelled colloid uptake by regional lymph nodes draining tumour was evident on gamma-camera scanning. (author)

    The needs of energy are increasing every year. The unavailability of energy will cause economic losses and weaken energy security. To overcome the availability of gas supply in the future, planning are cruacially needed. Therefore, it is necessary to approach the system, so that the process of gas distribution is running properly. In this research, system dynamic method will be used to measure how much supply capacity planning is needed until 2050, with parameters of demand in industrial, household and commercial sectors. From the model obtained PT.X Cirebon area in 2031 was not able to meet the needs of gas customers in the Cirebon region, as well as with Businnes as usual scenario, the ratio of gas fulfillment only until 2027. The implementation of the national energy policy that is the use of NRE as government intervention in the model is produced up to 2035 PT.X Cirebon area is still able to supply the gas needs of its customers.

    Radioactivity in and around the two hot springs, Oyoun Mossa and Hammam Faraun, Western Sinai has been determined. The ground water, sediment and sand samples were measured by gamma-ray spectrometer for 232 Th, 226 Ra and 40 K isotopes. The enrichment of 226 Ra in Hammam Faraun hot spring was the most prominent feature. The concentration of 226 Ra in Oyoun Mossa and Hammam Faraun hot springs are 68 and 2377 Bq/kg for sediments, 3.5 and 54.7 Bq/kg for wild plants, and 205 and 1945 mBq/l for the ground water, respectively. In addition, the concentration of sand samples are 14 times larger in the area of Hammam Faraun compared with that of Oyoun Mossa. On the other hand, the concentration of 232 Th in different samples are comparable in the two areas while 137 Cs concentrations are relatively higher in Oyoun Mossa. For the purpose of comparison, sand samples were collected from two locations 5-12 km away from each spring. The activity concentrations of the four locations are comparable and in agreement with those from the area of the two springs except in one case. The major difference was the activity concentration of 226 Ra in the area of Hammam Faraun, which is much higher. The concentrations of all detected isotopes in water samples from these two springs are much higher than that detected in 27 natural wells in north Sinai. The results of the present study indicate that water only in Hammam Faraun hot spring is contaminated with 238 U-isotopes and the surrounding area is affected by this contamination. The calculated annual effective dose equivalents in the surroundings of Hammam Faraun (81.8 μSv) is superior to the maximum contaminant levels recommended.

  19. GEOMORPHOSITES AS A VALUABLE RESOURCE FOR TOURISM DEVELOPMENT IN A DEPRIVED AREA. THE CASE STUDY OF ANINA KARSTIC REGION (BANAT MOUNTAINS, ROMANIA

    Full Text Available Geomorphosites are those landforms that in time, have acquired, a certain value, naming here scientific, cultural, aesthetic, ecological and/or economic. In many papers geomorphosites were associated with natural, relief-related tourist attractions. Those two notions, geomorphosite and natural tourist attraction are not synonymous, because a geomorphosite presents many features that give value to that landform. A geomorphosite is more than just topographic feature and that is the reason for which not all natural attractions are considered geomorphosite. Anina karstic region is synonymous with Anina Mining Area. This area was defined by Vasile Sencu (1977 as the area that is surrounded Anina town and it may be exploited by mining activities. The studied area presents many landforms specific for karst terrains. These features belong to the exokarst (sinkholes, poljies, karrens, gorges, karstic springs, but also to the endokarst (caves, shafts. The area is located in the largest and most compact area of carbonate rocks in Romania, in a typical structural area, Reșiţa-Moldova Nouă Synclinorium. Anina karstic region is an area with many socio-economical problems: poverty, unemployment and depopulation. Many landforms belonging to karst topography may be considered as geomorphosites due to their value (natural, economic, cultural. We believe that if some of these geomorphosites will be included in the touristic objectives, those landforms may generate a social-economic progress in this region, which nowadays is a deprived area. The aim of this paper is to point out that karstic geomorphosites in a deprived are may be a valuable resource.

    The frequency of chromosome aberrations (CA) was studied in peripheral blood lymphocytes from healthy children and children with thyreopathology living in the city of Klincy, Bryansk region (contamination level up to 5 Ci/km 2 ), and two Moscow groups, respectively. We have observed the elevated number of dicentrics and acentric fragments in cell from children with thyreopathology with respect from healthy children living in Klincy. This fact cannot be explained by influence of disease because there was no difference in cytogenetical markers between the groups of healthy children and children with thyreopathology from Moscow. The number of dicentrics was increased in cells from children with high level of internal contamination (more than 400 nCi) living in Krasnaya Gora (15-40 Ci/km 2 ). It is proposed that the internal irradiation is more important for the CA induction. The symmetrical translocation analysis using the method of fluorescence in situ hybridization (FISH) has shown the absence of this type of aberrations in cells from children with high level of internal irradiation whereas the translocations frequency in cells from control children was (1.1±0.4) per 1000 cells. 19 refs., 2 figs., 3 tabs

    The paper summarizes the results of a study concerning the operation of industrial plants and their effects to the environment. It also addresses, shortly, the consequences to the quality of human life and proposes potential measures that may contribute to the reduction of the negative environmental impacts. The relatively small organized Industrial Area of Alexandroupolis (Greece) is examined as a case study. In particular, the activities of its major industrial facilities are presented and their emissions to the environment are examined. In addition, the socio-economic aspects of the operation of the Industrial Area are studied. The results of the study showed that the operation of the Industrial Area has specific negative effects in the natural environment of the region and in the quality of life of the residents. Methodological and legislative tools, such as control systems for the environmental pollution, the green chemistry, and the environmental management systems, may be employed to assist the prevention and confrontation of environmental problems

    The aim of this study is to assess the ecological characteristics of El-Daba'a area in Egypt using GIS as a first step for the development of an environmental management plan for the area. The absence of environmental planning in the process of land use development may cause many significant negative impacts on biodiversity, ecological value and the general environmental conditions and the therefore reducing such negative impacts will improve land use development. The first part of sequel of two papers, which is a part of a sustainable land use development research program, aims at designing a spatial framework to improve land use planning and development in an environmental context. The research program deals with the problem of land use planning and development in an arid coastal area under environmentally sensitive conditions. The study area is El-Daba'a region, located in the northwestern coast of Egypt, which can be described as a wild area. The approach used in this paper consists of studying the spatial ecological characteristics of El-Daba'a region using different spatial data including maps and land sat remote sensing data. These data are used to create a series of superimposed informative layers managed by a geographic information system (GIS) to describe the spatial ecological characteristics of the study area. The developed GIS allow decision makers to handle large amounts of information simultaneously such as geology, geomorphology, land cover, wild life and many other different information layers. The system is designed to help decision makers to organize, relate, analyze and visualize the ecological data and information in the study area. The developed GIS system might be used to determine the probable effects of building a nuclear power station on the ecosystem. (author)

    Regional magnetic and gravity data of Papanaidupet area, Chitoor district, are discussed in the light of bore hole information for selection of target areas for uranium exploration. The low-pass filtered magnetic data shows a 'smooth' picture suppressing the high frequency components in the original data. The amplitude maxima of analytic signal outline the magnetic source at depth. The Bouguer gravity residual anomaly corresponding to a double sill-like model beneath is used to explain the borehole intercepts, after petro-physical studies of the borehole samples. (author)

    Nationwide health surveys can be used to estimate regional differences in health. Using traditional estimation techniques, the spatial depth for these estimates is limited due to the constrained sample size. So far - without special refreshment samples - results have only been available for larger populated federal states of Germany. An alternative is regression-based small-area estimation techniques. These models can generate smaller-scale data, but are also subject to greater statistical uncertainties because of the model assumptions. In the present article, exemplary regionalized results based on the studies "Gesundheit in Deutschland aktuell" (GEDA studies) 2009, 2010 and 2012, are compared to the self-rated health status of the respondents. The aim of the article is to analyze the range of regional estimates in order to assess the usefulness of the techniques for health reporting more adequately. The results show that the estimated prevalence is relatively stable when using different samples. Important determinants of the variation of the estimates are the achieved sample size on the district level and the type of the district (cities vs. rural regions). Overall, the present study shows that small-area modeling of prevalence is associated with additional uncertainties compared to conventional estimates, which should be taken into account when interpreting the corresponding findings.

    Phlebotomine sand flies are distributed across nearly all faunal regions of the world, represented by over 800 species, of which many are important vectors of human pathogens. Brazil is currently faced with the expansion and urbanization of leishmaniases, with an increase in the numbers of human cases and seropositive dogs in various medium-sized to large cities. The objective of the current study was to survey the phlebotomine sand fly species in an area endemic for American cutaneous leishmaniasis (ACL) and American visceral leishmaniasis (AVL), i.e., the municipal district of Santa Luzia, lying within the metropolitan region of Belo Horizonte in the Brazilian State of Minas Gerais. Sand flies were collected monthly in 2004-2005 using modified Falcão light traps hung in the peridomiciles of houses and surrounding wooded areas in the district of Baronesa. A total of 1,552 sand flies belonging to seven species was collected, and an interesting pattern of the distribution of the most abundant species relative to the sampling locality was revealed. In the wooded areas Lutzomyia whitmani (Antunes & Coutinho) predominated, whereas in the urban area Lutzomyia longipalpis (Lutz & Neiva) was the most abundant species. These results indicate two possible epidemiological patterns of Leishmania transmission in Santa Luzia: one for American cutaneous leishmaniasis associated predominantly with wooded areas, and another for AVL, with transmission principally occurring around human habitations.

    According to the IPCC latest report (IPCC, 2007) many semi-arid and arid areas, as the Mediterranean basin, are particularly exposed to the impacts of climate change and may suffer a decrease of water resources in the future. By the middle of the 21st century it is estimated that the annual average river runoff and water availability will decrease over these dry regions at mid-latitudes. So, it is of great importance the study of the future changes in the hydrological cycle, due to the increasing freshwater demands. The main scope of the present study is to estimate the future changes of the surface runoff in the Aravissos area (central Macedonia - Greece) due to the enhanced greenhouse effect until the end of the 21st century. The selection of Aravissos was based to the fact that the water needs of the second largest in population city in Greece (Thessaloniki) are covered mainly by the selected catchments area. Daily precipitation, temperature, relative humidity, wind speed and sunlight duration data derived from updated regional climate models, are used for selected grid points covering the domain of study. The main two climatological parameters (precipitation -temperature) are on a first step evaluated in comparison to re-analysis data (E-Obs -Ensembles project) for the same grid points. On a second step, utilizing several different evapotranspiration methods we calculated the surface runoff for two different time periods: the first in the middle and the second at the end of the 21st century. The first results of the study showed that the surface runoff depends on the methodology used for the calculation of the evapotranspiration but also from the regional model.

    We have investigated the correlation and chronology of fluvial terraces, and characteristics of terrace distribution around active structures, in the Mid Niigata region. Making much of geomorphologic and geologic information, such as morphology and continuity of terrace plains, weathering of terrace gravels, gives to appropriately interpretation of tephra data. Then, at both sides of the active structure, characteristics of terrace distribution are quite different. It indicates that terrace distribution is useful information to evaluate fault activity. Furthermore, uplift estimation for the last 100,000 years is given by terrace distribution information and relative heights of fluvial terraces, and can be applied to evaluation the fault activity. For example, using the uplift index of the values of relative height between terraces, we estimated that the uplift difference on the both side of the Muikamachi fault during late Quaternary was more than 40m. It suggests that the slip rate of the Muikamachi fault is more than 0.4m/10 3 year. The viewpoint and method shown in this paper reflected to the upgrade of the air-photo interpretation for active fault survey. (author)

    Agricultural lands that supply food, energy and ecosystem services for human life have been lost due to anthropogenic activities such as construction of roads, urban and industry areas. The significant reasons for the increase of artificial surfaces were poorly planned economic decisions by the government and internal migration due to this poorly planning. Unplanned urban sprawl also give rise to land fragmentation. Fragmentation of agricultural land affects both the agricultural production capacity and rural sustainable employment. In this study: i) Land use changes between 1990-2014 period were assessed using remotely sensed data and ii) Spatial and temporal agricultural land fragmentation were investigated using landscape pattern indice (effective mesh size), Morphological Spatial Pattern Analysis (MSPA) and Entropy method for 25 years period. The selected"hot spot" study area is located on east Thrace region of Turkey, being the service and industrial development zone where agricultural activities, water resources and natural habitat have been damaged due to rapid urban and industrial development for about 25 years. The results showed that agricultural lands decreased 6.44%, urban areas increased 111.68% and industry areas increased 251.19% during this 25 years period. Additionally, fragmentation analyses demonstrated that core agricultural areas sharply decreased and relative fragmentation (effective mesh size) increased from 50.68% to 56.77% during 1990 and 2014.

    Full Text Available Earth's gravity model (EGM helps people better determine the figure of Earth, which is generally represented by a global geoid. For a considerable amount of practical applications, people use quasi-geoid to approximate the geoid, thus the quasi-geoid is also treated as an important height datum. In this study we revisit the method to directly determine regional quasi-geoid using EGM and digital elevation model (DEM, on the basis of Molodensky theory. According to the method we obtain a 5′ × 5′ quasi-geoid for Mainland China and its vicinity areas, based on the EGM2008 gravitational potential model and the Shuttle Radar Topography Mission (SRTM DEM model. By comparing height anomalies derived from EGM2008 with observations at 70 GPS/leveling points in areas including northwest, mid-west, mid-east and southeast of China, we find that the 5′ × 5′ EGM2008 quasi-geoid well fits the GPS/leveling results, with average deviations less than 10 cm for the selected areas in east China (with mainly plain topography and ∼20 cm for the selected areas in west China (highland or mountainous areas. We also discuss a few technical issues for directly determining height anomalies based on EGM and DEM, under the frame of Molodensky theory.

    To estimate the management of UC associated costs from the societal perspective in Spain. Observational, longitudinal study with retrospective data collection based on reviews of outpatient health records. Socio-demographic, clinical and sick leave information was gathered. Patients diagnosed of UC between 2002 and 2012, older than 18 years, followed-up by a minimum of 12 months post diagnosis, with at least two clinical and use of resources data recorded, were included. 285 UC patients [51.2% men; 44.5 (SD: 15.6) years old; 88.4% without family history of UC; 39.3% proctitis; 5.6 (2.5) years disease follow-up] participated. More than half (65.6%) were active workers, 75.9% were on sick leave for reasons different from UC [mean 0.66 (0.70) times per year] during (mean) 28.43 (34.45) days. Only 64 patients were on UC-related sick-leaves, lasting (mean) 26.17 (37.43) days. Absenteeism due to medical visits caused loss of 29.55 (21.38) working hours per year. Mean direct and indirect annual cost per UC patient were €1754.10 (95%CI: 1473.37-2034.83) and €399.32 (282.31-422.69), respectively. Absenteeism was estimated at €88.21(32.72-50.06) per patient per year, in which sick-leaves were the main component of indirect costs (88.2%). Age, UC family history, diarrhea at diagnosis, blood and blood-forming organs diseases and psychological disorders were the main predictors of indirect costs. UC is a costly disease for the society and the Spanish National Healthcare System. Indirect costs imply a major burden by affecting the most productive years of patients. Further research is needed considering all components of productivity loss, including presenteeism-associated costs. Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.

    The contemporary conditions of academic capitalism exert pressures on researchers to avoid ‘peripheral’ journals and ‘unfashionable’ topics. Here an attempt is made to shed light onto the structure of one such ‘offbeat’ field, namely ‘border region studies’, by discussing its geographical...... distribution, key themes, significance and impact. The review suggests that border region studies can be considered a significant and important ‘branch’ of regional studies, which accounts for a small but increasing proportion of regional studies research particularly in Europe and North America.

    1982-01-01

    Regional gravity and aeromagnetic data have been used to investigate the three dimensional structure of the Cheviot igneous complex and surrounding sedimentary formations. The Bouguer Gravity Anomaly map is dominated by a large negative anomaly of -19 mgals centred over the Cheviot granite. In the surrounding area additional negative anomalies due to low density andesitic and rhyolitic lavas, and to Devonian and Lower Carboniferous sediments interfere and overlap with the anomaly due to the granite. The field due to the granite has been separated from that due to the near surface formations and interpreted in terms of a body which reaches the surface over the central part of the mapped granite outcrop and extends to a depth of about 9 km. The density of the body corresponds roughly to that of the central acid phases of the outcrop. The contacts slope outwards beneath the denser marginal granite to reach a diameter of about 35 km at 9 km depth. The aeromagnetic anomaly map is dominated by a large (400 nT) positive anomaly over the highly magnetic marginal granite and metamorphosed lavas, with a low over the weakly magnetised central granite. The results are discussed. (author)

    Environmental sampling can be used to complement the safeguarding of nuclear material, especially in the detection of undeclared nuclear activities. Routine monitoring of nuclear installations has provided valuable information about the fate of key signature materials within different environmental settings. The approach collates information regarding the generation of individual radiochemical signatures within different nuclear processes, the potential for release of these signatures to the environment and, the chemical form and mobility of the signatures in environmental media along which the material could migrate. Meteorological, geological and hydrological information is used to determine where to sample, what to sample, and how often to sample to provide the greatest likelihood for detection. Multiple strategies can be used to implement wide area monitoring for safeguards purposes. The most complex, and expensive of these, involves establishing extensive networks of fixed location sampling sites. The sites would be operated continuously, and would be instrumented with automated sampling, analysis, and communication equipment to relay information regarding potential anomalies to control centers in near-real time. Alternative strategies can be used to supplement fixed location monitoring equipment, especially in regions that cannot support (financially or logistically) the fixed stations. Through combinations of these various strategies, using a variety of environmental media to monitor a region, we believe that a competent network, one with a quantifiable probability for detecting undeclared nuclear activities, can be designed. While this approach cannot and should not replace other inspection and monitoring activities, it can potentially contribute valuable information to an international safeguards system. (author)

    Due to the various types of waste disposal, treatment, utilization and technologies, decision support model for waste management is needed to assist planners and decision makers in finding most suitable way to manage municipal solid waste efficiently. Many planners and decision makers in the area of municipal solid waste have a lack of thorough understanding of the complex chains of waste management system. Therefore the impact for the environment quality and the public health can only be judged at the rudimentary level. However, most existing models are primarily focusing on cost or environmental analysis. Only few consider other crucial factors such as the demographic condition, the characteristics of urban form and urban infrastructure, land transformation aspects due to urban development. Consequently, such models often meet difficulties to cope with cultural requirement. Based on those reasons, a decision support model to set up alternatives of most appropriate technology for sustainable waste management towards a low carbon eco-city on a regional basis is developed in this PhD study. The Low Carbon- and Eco-Region, in particular the contribution of waste management sector, is a vision of living in low rate of carbon generation, using fewer natural resources, and encouraging energy recovery and/or waste reduction at source by improving the used material quality (up-cycling). This decision support model is constructed mainly based on the cultural requirement and local context of a region and synergize the geographic, environmental, social capital and economics aspects in order to fulfill the needs of the respective region and its society. The method employed in this model is not solely a new developed model, but also an advanced model in material flow analysis (STAN), and life cycle assessment on solid waste system (EASEWASTE) and Geographic Information System (GIS). At the same time the model also assists the stakeholders in improving the environmental quality

    Methylation of inorganic Hg in aquatic systems is a key process in the environmental cycling of this metal, not yet studied in tropical conditions. Radiochemical techniques were adapted and simplified, aiming at the study of Hg volatilization and methylation in water and sediment of gold mining areas in the Amazon region. Preliminary experiments showed, in 35 days volatilization of up to 32 % of 203 Hg 2+ added to aqueous solutions. Acid K 2 Cr 2 0 7 0.1 M solutions were not effective in 203 Hg 0 trapping and the latter was highly and irreversibly absorbed by a variety of synthetic materials commonly used in laboratory work. Considerably simplified versions of the Furutani and Rudd (1980) radiochemical technique for the determination of methylation rates in environmental samples were developed and showed efficiencies close to 90 % in tests with methyl- 2 0 3 H g standards. In-situ incubations of surface sediments were performed in the Madeira River gold mining region, Rondonia State, Brazil, and potential net Hg methylation rates (MR) of up to 1 %.g-1.h-1 were found in black-water affluent like the Mutum-Parana and Jamari rivers and in the Samuel reservoir. MRs in the Madeira River sediments were lower, ranging 10-5 to 10-3 %.g-1.h-1 . MRs obtained in incubations of samples some weeks after collection were one or two orders of magnitude lower than those resulting from in-situ incubations. Methylation in autoclaved samples was close to minimum detectable rates. MRs in surface water samples was in all cases < 7.10-7 %.ml-1.h-1. The determination of the predominant methylation sites will allow a better standardization of the technique described herein, suitable for MR determinations even under the unfavorable conditions prevailing in the Amazon region.

    Forest roads are essential for transport in managed forests, yet road construction causes environmental disturbance, both in the surface area the road covers and in erosion and downslope deposition of road fill material. The factors affecting the deposition distance of eroded road fill are the slope gradient and the density of plant cover. Thus, it is important to take these factors into consideration during road planning to minimize their disturbance. The aim of this study was to use remote sensing and field surveying to predict the locations that would be affected by downslope deposition of eroding road fill and to compile the data into a geographic information system (GIS) database. The construction of 99,500 m of forest roads is proposed for the Kastamonu Regional Forest Directorate in Turkey. Using GeoEye satellite images and a digital elevation model (DEM) for the region, the location and extent of downslope deposition of road fill were determined for the roads as planned. It was found that if the proposed roads were constructed by excavators, the fill material would cover 910,621 m(2) and the affected surface area would be 1,302,740 m(2). Application of the method used here can minimize the adverse effects of forest roads.

    Full Text Available Agricultural and industrial conditions are not favourable in the uphill and mountain areas of the Zamagurie region, and tourism is often the only opportunity to create new jobs, develop the habitation areas and avoid the emigration of local inhabitants. The Walachian and Sholtys colonization has transformed the landscape and created unique significant spatial landscape elements that are traditionally utilized for agricultural purposes, and create a unique esthetical landscape preserved till the present times. This case study has been aimed at developing and applying the new quantification methods using GIS tools for evaluation of localizing, selective realization and environmental preconditions of the landscape, representing recreational (cultural services of the landscape ecological systems, based on selected indicators. To evaluate the localizing preconditions of the landscape, we referred to the landscape-ecological complex geo-databases (LEC (Thematic maps - internal ground document of ZB GIS , 2013, completed with the field survey during the period 2013−2014 and identification of secondary landscape structure elements (SLS and selected morphometric indicators. While evaluating the selected town-planning, demographical and social-economic indicators, we quantified the selective landscape preconditions of tourism development. The realization preconditions were reviewed according to communication accessibility and material-technical equipment. As for environmental preconditions, we reviewed the presence of protected territory and landscape environmental load.

    Full Text Available Extreme Event Attribution has raised increasing attention in climate science in the last years. It means to judge the extent to which certain weather-related extreme events have changed due to human influences on climate with probabilistic statements. Extreme Event Attribution is often anticipated to spur more than just scientific ambition. It is able to provide answers to a commonly asked questions after extreme events, namely, ‘can we blame it on climate change’ and is assumed to support decision-making of various actors engaged in climate change mitigation and adaptation. More in-depth research is widely lacking about who these actors are; in which context they can make use of it; and what requirements they have, to be able to actually apply Extreme Event Attribution. We have therefore addressed these questions with two empirical case studies looking at regional decision-makers who deal with storm surge risks in the German Baltic Sea region and heat waves in the Greater Paris area. Stakeholder interviews and workshops reveal that fields of application and requirements are diverse, difficult to explicitly identify, and often clearly associated with stakeholders' specific mandate, the hazard background, and the regional socio-economic setting. Among the considered stakeholders in the Baltic Sea region, Extreme Event Attribution is perceived to be most useful to awareness-raising, in particular for climate change mitigation. They emphasised the importance of receiving understandable information - and that, rather later, but with smaller uncertainties than faster, but with higher uncertainties. In the Paris case, we typically talked to people engaged in adaptation with expertise in terms of climate science, but narrowly defined mandates which is typical for the Paris-centred political system with highly specialised public experts. The interviewees claimed that Extreme Event Attribution is most useful to political leverage and public

    Full Text Available Objective. The objective of the study was measurement of the concentrations of airborne asbestos fibres in the rural environment of the Lublin Region in south-east Poland. Methods. Measurements of concentrations of respirable asbestos fibres were carried out in the rural areas of the Lublin Region (Lublin and Włodawa counties for a period of 24 months. The studies were conducted on 3 farms with various technical conditions of asbestos-containing materials: Farm A – good technical condition of asbestos products, Farm B – poor technical condition, and Farm C – with no asbestos containing products and no such products in its direct vicinity (up to 500 m. On the selected farms, 3 samples on each were simultaneously collected at 3 measuring sites. During the period 2009–2011, a total number of 216 samples were collected on all farms. Sampling was performed using JSH 16,000 stationary aspirators, with air flow velocity of 16 l/min. and sampling time 60–80 minutes. The number of fibres on filters was determined using an optical phase contrast microscope. Results. The study showed that the mean concentration of respirable asbestos fibres on the farms examined was 296 fibres•m [sup]-3[/sup]. The highest concentrations were noted on Farm B was 529 fibres•m [sup]-3[/sup], on average; on farm A the mean concentration of respirable fibres was 328 fibres•m [sup]-3[/sup] , whereas the lowest mean concentration of airborne respirable asbestos fibres was noted on farm C, where there were no asbestos products (30 fibres•m [sup]-3[/sup] .

    The NRC Office of Inspection and Enforcement (IE) has elected to evaluate the effectiveness and efficiency of its existing regional boundary alignment because of the anticipated future growth of nuclear power generating facilities and corresponding inspection requirements. This report documents a management study designed to identify, analyze, and evaluate alternative regional boundary configurations for the NRC/IE regions. Eight boundary configurations were chosen for evaluation. These configurations offered alternatives ranging from two to ten regions, and some included the concepts of subregional or satellite offices. Each alternative configuration was evaluated according to three major criteria: project workload, cost, and office location. Each major criterion included elements such as management control, program uniformity, disruption, costs, and coordination with other agencies. The conclusion reached was that regional configurations with regions of equal and relatively large workloads, combined with the concepts of subregional or satellite offices, may offer a significant benefit to the Office of Inspection and Enforcement and the Commission and are worthy of further study. A phased implementation plan, which is suitable to some configurations, may help mitigate the disruption created by realignment

    Full Text Available Two main perspectives of investigation emerge from the study of a territory’s rurality: a geographical approach and a sociological approach. The research examines the sub-regional study case of ‘Nuovo circondario imolese’. The analysis shows that the combination of traditional institutional criteria with detailed informations about the territory, generates more accurate results which determine a better comprehension of the characteristics of restricted areas’ rurality. Over the period 1991-2001, the study highlights an increase in rural areas. This result could be interpreted as an effect of urban sprawl’s intensification, that increases the competition between non-farm residences and agricultural activities.

  10. Regional Resource Planning Study

    International Nuclear Information System (INIS)

    2001-01-01

    Natural gas and electricity commodities are among the most volatile commodities in the world. Spurred on by the recent significant increases in the price of natural gas, the BC Utilities Commission initiated an investigation into factors impacting on natural gas prices, and the validity of the Sumas index (a market trading point, or interchange where multiple pipelines interconnect, allowing the purchase and sale of gas among market participants) as a price setting mechanism. The Commission also sought the opinions and perspectives of the the province's natural gas industry regarding the high volatility of the Sumas gas prices, and as to what could be done to alleviate the wild fluctuations. Following review of the responses from stakeholders, the Commission issued a directive to BC Gas to undertake discussions on regional resource planning with full representation from all stakeholders. This study is the result of the Commission's directive, and is intended to address the issues contained in the directives. Accordingly, the study examined gas demand in the region, demand growth, including power generation, natural gas resource balance in the region, the California impacts on demand and on supply to the region, supply shortfalls on a peak day, and on a seasonal and annual basis, near term remedies, possible resource additions in the longer term, the economic justification for adding major resources and proposed actions to develop needed resource additions. The study confirmed the existence of a growing capacity deficit, which limits the supply of natural gas to the region. Near term options to alleviate the regional capacity deficit were found to be limited to discouraging power generation from serving export markets, demand side management efforts, and expansion of the WEI's systems by 105 mmcf/d. Longer term solutions would involve larger scale expansion of WEI's T-South capacity, the BC Gas' Inland Pacific Connector Project and the Washington Lateral proposed by

    2012-03-01

    Full Text Available The Eurasian area has a very rich energy reserves, and is characterized by a complex network of relationships between major suppliers and consumers. The central place in this area has Russia as a country richest in energy resources in Eurasia. Beside her, the European Union is the largest economic and political grouping in the world, and a huge consumer of energy. The dynamic development of Chinese economy requires more energy imports by China. Dependence of the European Union and China on imported energy is high and will grow in the future. Russia is the world's dominant natural gas producer and one of the two largest oil producers in the world. Russia is the largest natural gas supplier of the EU and a significant oil and natural gas supplier of China. Energy projects in Eurasia are the result of the need to strengthen the stability of energy supplies, efforts to diversify sources of supply, and the geographic redistribution of Russian oil and gas exports. Although the interests of the main actors often do not agree, the reasons of energy security affect the development of joint energy projects.

    Urban areas are usually warmer than their surrounding natural areas, an effect known as the urban heat island effect. As such, they are particularly vulnerable to global warming and associated increases in extreme temperatures. Yet ensemble climate-model projections are generally performed on a scale that is too coarse to represent the evolution of temperatures in cities. Here, for the first time, we combine unprecedented long-term (35 years) urban climate model integrations at the convection-permitting scale (2.8 km resolution) with information from an ensemble of general circulation models to assess temperature-based heat stress for Belgium, a densely populated midlatitude maritime region. We discover that the heat stress increase toward the mid-21st century is twice as large in cities compared to their surrounding rural areas. The exacerbation is driven by the urban heat island itself, its concurrence with heat waves, and urban expansion. Cities experience a heat stress multiplication by a factor 1.4 and 15 depending on the scenario. Remarkably, the future heat stress surpasses everywhere the urban hot spots of today. Our results demonstrate the need to combine information from climate models, acting on different scales, for climate change risk assessment in heterogeneous regions. Moreover, these results highlight the necessity for adaptation to increasing heat stress, especially in urban areas.

    2014-05-15

    Urbanization has accelerated in China, and a large amount of arable land has been transformed into urban land. Moreover, the number of landless peasants has continually increased. Peasants lose not only their land, but also a series of rights and interests related with land. The problems of landless peasants have been long-standing; however, only a few studies have examined their health or quality of life (QOL). This paper assesses the QOL of landless peasants in the Yangtze River Delta (YRD) region, analyzes gender differences, and explores health inequity. Data are derived from household samples in six resettlement residential areas of three cities (Nanjing, Hangzhou, and Yangzhou) in the YRD region (N = 1,500; the effective rate = 82.4%). This study uses the short version of World Health Organization Quality of Life questionnaire (WHOQOL-BREF) scale to measure the QOL of landless peasants, and performs confirmatory factor analysis (CFA) and analyze gender differences in QOL on the basis of CFA. First, we use Analysis of Variance and Non-parametric Tests to test if the differences of mean value of testing generals have statistical significances. Results shows significant differences occur between the impacts of different genders on the four domains of QOL (physical health, psychological health, social relationships, and environment). The internal reliability of the WHOQOL-BREF scale is good (Cronbach's alpha > 0.8), and the four domains of QOL are connected with each other. Second, scores in each QOL domain are commonly low, whereas the scores of females are much lower, indicating a poorer QOL than that of males. Third, results of the CFA of the QOL domains and their related observed variables indicate a good model fit. Fourth, results imply that the order of importance of the four domains (psychological health (males = 26.74%, females = 27.17%); social relationships (males = 26.23%, females = 25.35%); environment (males = 25

    1999-10-01

    New opportunities for climate change mitigation arising from a higher energy integration among Andean Pact nations were analysed within the framework of the UNEP/GEF Project. Apart from the search for regional mitigation actions, the study was mainly aimed at detecting methodological problems which arise when passing from a strictly national view to the co-ordination of regional actions to deal with climate change. In accordance with the available resources and data, and in view of the mainly methodological nature of the project, it was decided to analyse the opportunities to delve into the energy integration of the Region as regards electricity and natural gas industries and their eventual impact on the emission of greenhouse gases. Although possibilities of setting up electricity and natural gas markets are real, their impacts on GHG emission from the energy system would not prove substantially higher than those which the nations could achieve through the use of their own energy resources, in view that the Andean systems are competitive rather than complementary. More in-depth studies and detail information will be required - unavailable for the present study - to be able to properly evaluate all benefits associated with higher energy integration. Nevertheless, the supply of natural gas to Ecuador seems to be the alternative with the highest impact on GHG emission. If we were to analyse the supply and final consumption of energy jointly, we would most certainly detect additional mitigation options resulting from higher co-operation and co-ordination in the energy field.

    More than one hundred group velocity dispersion curves of the fundamental mode of Rayleigh waves have been processed to obtain tomographic maps, in the period range from 10 s to 35 s, for the Italian peninsula and bordering areas. We compute average dispersion relations over a 1 deg. x 1 deg. grid, and, since the lateral resolving power of our data set is about 200 km, we group the cells of the grid accordingly to their dispersion curves. In this way and without a priori geological constraints, we define seven different regions, each characterised by a distinctive mean group velocity dispersion curve. The resulting regionalization can be easily correlated with the main tectonic features of the study area and mimics a recently proposed structural sketch. Average models of the shear wave velocity in the crust and in the upper mantle for a few selected regions are presented. The very low S-wave velocity values found in the uppermost upper mantle of the Southern Tyrrhenian basin are consistent with a large percentage of partial melting, well in agreement with the presence of the Vavilov-Magnaghi and Marsili huge volcanic bodies.

    The Pedra Wilderness Study Area, located approximately 30 mi northeast of Durango, Colorado, was evaluated for its mineral-resource potential. Geochemical and geophysical studies indicate little promise for the occurrence of mineral or energy resources in this area. This conclusion is supported by the findings of the earlier study and is suggested by the absence of significant mining activity in the area.

    It is well established that indoor radon-thoron and daughters are the largest contributor to total radiation dose received by populations. They account for more than 50% of the total dose and the radiation exposure beyond permissible levels can lead to deleterious effects on health. This fact necessitates extensive studies of natural radioactivity levels in the stone mining area of Aravali range in Faridabad. The stone mining area of Aravali Range in Pali, District Faridabad bears significant geological features. Radon exhalation from ground plays an important role in enhanced indoor radon levels and can pose grave health hazards to the workers and the residents. Exhalation rates (mass and surface) from stone samples of the area have been studied using LR-115, Type II nuclear track detectors. The mass and surface exhalation rates from crushed stone samples, also called stone dust varied in the range 3.41-9.11 mBq kg -1 h - 1 and 75.9-202.7 mBq m -2 h -1 , respectively. The study has revealed substantial presence of radionuclides in the samples collected from the mining area. (author)

    In this work, we take advantage of 11 different sunspot group, sunspot, and active region databases to characterize the area and flux distributions of photospheric magnetic structures. We find that, when taken separately, different databases are better fitted by different distributions (as has been reported previously in the literature). However, we find that all our databases can be reconciled by the simple application of a proportionality constant, and that, in reality, different databases are sampling different parts of a composite distribution. This composite distribution is made up by linear combination of Weibull and log-normal distributions—where a pure Weibull (log-normal) characterizes the distribution of structures with fluxes below (above) 10{sup 21}Mx (10{sup 22}Mx). Additionally, we demonstrate that the Weibull distribution shows the expected linear behavior of a power-law distribution (when extended to smaller fluxes), making our results compatible with the results of Parnell et al. We propose that this is evidence of two separate mechanisms giving rise to visible structures on the photosphere: one directly connected to the global component of the dynamo (and the generation of bipolar active regions), and the other with the small-scale component of the dynamo (and the fragmentation of magnetic structures due to their interaction with turbulent convection)

    From 1990 to 1999, estimations of the effective dose from external as well as internal irradiation from {sup 137}Cs and {sup 134}Cs were carried out for inhabitants in rural villages in the Bryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. The villages were situated about 180 km from the Chernobyl power plant and the deposition of {sup 137}Cs was in the range 0.9-2.7 MBq/m{sup 2}. Yearly expeditions were conducted in autumn by members of the Departments of Radiation Physics in Malmoe and Goeteborg, Institute of Radiation Hygiene, St. Petersburg and the the first 5 years also by the Norwegian Radiation Protection Authority. The dose levels and their change in time were estimated for various groups of the general public. The body burden of {sup 134,137}Cs and hence, the effective dose, was estimated from measurements of the urinary concentration of cesium radionuclides, together with direct measurements of the body content using a portable detector. The effective dose from external irradiation was estimated from measurements with thermoluminescent dosemeters worn by the participants during one month each year. In a special case study, the changes in biokinetics of {sup 137}Cs during pregnancy was investigated in a woman with an unintended intake of {sup 137}Cs via mushrooms from a highly contaminated forest in the area. During pregnancy there is an increased excretion of cesium resulting in a biological half-time of cesium which was 54% of the half-time before pregnancy. The ratio of the {sup 137}Cs concentration in breast milk (Bq/l) to that in the mother's body (Bq/kg) was 15% one month after the child was born. The body burden of {sup 137}Cs in the Russian individuals calculated from the concentration of {sup 137}Cs in urine showed a good agreement with the body burden estimated from in vivo measurements in the same individuals.

    In order to perform retrospective estimations of radiation doses seven years after the nuclear accident in Chernobyl, the frequencies of chromosomal aberrations in the peripheral blood lymphocytes of individuals living in contaminated areas around Chernobyl and the Estonian clean-up workers were determined. The first study group composed of 45 individuals living in four areas (i.e. Rechitsa, Komsomolski, Choiniki and Zaspa) in the vicinity (80-125 km) of Chernobyl and 20 individuals living in Minsk (control group - 340 km from Chernobyl). The second study group (Estonian clean-up workers) composed of 26 individuals involved in cleaning up the Chernobyl for a different period of time (up to 7 months) and a matched control group consisting of 9 probands. Unstable aberrations (dicentrics and rings) were scored in Giemsa stained preparations and stable aberrations (translocations) were analyzed using chromosome specific DNA libraries and fluorescence in situ hybridization (FISH) technique. For both study groups the estimated average dose is between 0,1-0,4 Gy. Among the people living in the contaminated areas in the vicinity of Chernobyl, a higher frequency of numerical aberrations (i.e. trisomy, hyper diploidy) was evident

    As the worst civilian nuclear accident, the Chernobyl disaster presented the authorities first in the Soviet Union and then in the independent republics with an unprecedented problem. Strenuous and costly efforts were made to limit the effects of the accident and then to cope with the evacuation or rehabilitation as appropriate of the contaminated areas. By the mid-1990's, however, there was increasing evidence that the problems were over-taxing traditional responses. Into this context, a French team of specialists from a range of disciplines entered with a view to attempting improvements, but without preconceived ideas of what they would do or how they would do it. Beginning by listening to the people of the area of Belarus selected for the so-called ETHOS project, they discovered a profound distrust of the authorities and experts born of the perceived shortcomings of the official responses to the problems to date. They thus worked in close co-operation with the people both to identify the problems that concerned them and to develop solutions that took account of local opportunities and constraints. This interim report on a case study examining the ETHOS project is based on interviews with a wide range of people in the area of the project. It presents the problems identified by interviewees with the initial responses of the authorities and then their assessment of the ETHOS approach. The overall finding is that where public confidence has been lost in the context of an event such as the Chernobyl disaster, the authorities need to make a special effort to establish trust to a point where confidence returns. Traditional top-down responses appear to have exacerbated and reinforced the loss of confidence in this case whereas the approach of the ETHOS team appears to have succeeded in building trust to a significant degree - perhaps even to a point where there may be evidence that confidence is returning.

    Wind speeds in remote areas are sometimes very high, but transmission costs to access these locations can be prohibitive. We present a conceptual model to estimate the economics of accessing high quality wind resources in remote areas to comply with renewable energy policy targets, and apply the model to the Midwestern grid (MISO) as a case study. We assess the goal of providing 40 TWh of new wind generation while minimizing costs, and include temporal aspects of wind power (variability costs and correlation to market prices) as well as total wind power produced from different farms. We find that building wind farms in North/South Dakota (windiest states) compared to Illinois (less windy, but close to load) would only be economical if the incremental transmission costs to access them were below $360/kW of wind capacity (break-even value). Historically, the incremental transmission costs for wind development in North/South Dakota compared to in Illinois are about twice this value. However, the break-even incremental transmission cost for wind farms in Minnesota/Iowa (also windy states) is $250/kW, which is consistent with historical costs. We conclude that wind development in Minnesota/Iowa is likely more economical to meet MISO renewable targets compared to North/South Dakota or Illinois. - Highlights: •We evaluate the economics of building wind farms in remote areas in MISO. •We present a conceptual wind site selection model to meet 40 TWh of new wind. •We use the model to compare remote windy sites to less windy ones closer to load. •We show break-even transmission costs that would justify remote wind development. •Comparing break-even values to historical costs, MN/IA sites are most economical.

    A comparative study of knowledge, attitude and practice regarding referral system was undertaken among all governmental primary health care and private dispensary physicians (56 and 50 respectively) in Abha and Kamis, Asir Region. Results show that knowledge about referral is adequate in both groups, but the attitudes and practice of both groups need to be positively modified specially among the private sector physicians. The paper recommends more orientation programs for both groups of physicians and urges the private sector physicians to be more involved in Ministry of Health training programs and activities. Cooperation in referral between the private sector and government hospitals is seen as one way of improving health care in Saudi Arabia.

    This article describes regional differences in the homicide patterns which occurred in Sapporo City and the surrounding area, and in Akita, Ibaraki, Chiba and Toyama prefectures in Japan. Information collected from each case of homicide included factors such as age, sex of the victim and assailant, causes of death, disposition of the offender, relationship between assailant and victim, reasons for criminal action, et al. The statistical features of homicidal episodes among the five different regions showed considerable variation, as follows. The mean death rates for homicide (number of victims per 100,000 of population) during the period 1986-1995 were 0.44 (Sapporo), 0.8 (Akita), 0.58 (Toyama), 0.7 (Ibaraki) and 0.75 (Chiba), respectively. Close family relationship between the victim and assailant was observed in the homicidal acts which occurred in Sapporo, Akita and Toyama. Assailant's relationship to victim was commonly extra-familial in Ibaraki and Chiba-neighboring megalopolis Tokyo, where some events of murder by a foreigner occurred. Homicide by female assailant, murder by mentally abnormal killers and homicide-suicide events were closely associated with family members. And these factors contributed to the considerable number of victims in Sapporo, Akita and Toyama. But, this close family relationship of the victim to the assailant did not correspond with the elevation in the number of deaths, and it was rather inversely related to the higher death rates recognized in Ibaraki and Chiba. This comparative study suggested that rapid urbanization considerably affects regional differences in homicide patterns.

    Full Text Available The current state estimators need to estimate the power system by means of the state variables i.e. voltage and current phasors accurately. Phasor measurement unit (PMU is becoming a most prominent tool for monitoring, control and protection of electric networks, and hence it is required to employ them for the present and future power system networks. An optimal PMU placement (OPP is quite important during planning studies for both existing and future power networks. So, when a new state estimator commissioned, or an existing estimator is up-graded, the problems of minimizing the number of PMUs and their optimal location for system complete observability will come into picture. The approach, in this paper, a Binary Cuckoo Search(BCS method for system complete Observability based optimal PMU placement problem subjected to all possible contingencies and PMU communication channel limitations is suggested. The suggested method is tested with some of standard IEEE test systems and have been practiced for different State Level Regional power Grids (SLRGs of the Indian power system. The results from the suggested method are also compared with the methods that have been already applied for standard IEEE test systems and SLRGs, and were proved to be best and effective.

    Poland has a turbulent and rich history. Partitions, wars, a centrally planned economy of the socialist era and the rapid transition to a market economy left visible marks on the Polish landscape. The changes that took place in the 20th century and the early 21st century have vastly influenced the country’s architecture. Residential buildings in rural suburbs bear witness to turbulent historical events and change processes. This study analyzed residential buildings in two villages situated in the historical district of Warmia (north-eastern Poland) which is now a part of the Region of Warmia and Mazury. The results of the observations were used to review the social, economic, legal and planning factors that influenced residential architecture between 1900 and 2017. The traditional layout of Warmian villages is well preserved in the analyzed locations where pre-war architectural design mingles with buildings erected in the socialist era when construction materials were scarce. Many buildings in the surveyed villages are reminiscent of collective farms, the prescribed architectural style of the 1970s as well as the stylistic diversity of the early transformation period when customized building plans and construction materials became available. The local landscape also features buildings erected in successive decades which brought a significant increase in the price of land and maintenance costs.

    RAQSIM, a generalized flow model of a groundwater system using finite-element methods, is documented to explain how it works and to demonstrate that it gives valid results. Three support programs that are used to compute recharge and discharge data required as input to RAQSIM are described. RAQSIM was developed to solve transient, two-dimensional, regional groundwater flow problems with isotropic or anisotropic conductance. The model can also simulate radially-symmetric flow to a well and steady-state flow. The mathematical basis, program structure, data input and output procedures, organization of data sets, and program features and options of RAQSIM are discussed. An example , containing listings of data and results and illustrating RAQSIM 's capabilities, is discussed in detail. Two test problems also are discussed comparing RAQSIM 's results with analytical procedures. The first support program described, the PET Program, uses solar radiation and other climatic data in the Jensen-Haise method to compute potential evapotranspiration. The second support program, the Soil-Water Program, uses output from the PET Program, soil characteristics, and the ratio of potential to actual evapotranspiration for each crop to compute infiltration, storage, and removal of water from the soil zone. The third program, the Recharge-Discharge Program, uses output from the Soil-Water Program together with other data to compute recharge and discharge from the groundwater flow system. For each support program, a program listing and examples of the data and results for the Twin Platte-Middle Republican study are provided. In addition, a brief discussion on how each program operates and on procedures for running and modifying these programs are presented. (Author 's abstract)

    2013-07-01

    Full Text Available Geomorphologial approach can be used as the basic for identifying and analyzing the natural resources potentials, especially in volcanic landscape. Based on its geomorphology, Merapi volcanic landscape can be divided into 5 morphological units, i.e.: volcanic cone, volcanic slope, volcanic foot, volcanic foot plain, and fluvio-volcanic plain. Each of these morphological units has specific characteristic and natural resources potential. Based on the condition of geomorphology, the regional zoning can be compiled to support the land use planning and to maintain the conservation of environmental function in the Merapi Volcanic area.

    To date, numerous Jurassic hydrocarbon fields and pools have been discovered in the Cotton Valley Group, Haynesville Formation, Smackover Formation and Norphlet Formation in the tri-state area of Mississippi, Alabama and Florida, and in Alabama State coastal waters and adjacent Federal waters area. Petroleum traps are basement highs, salt anticlines, faulted salt anticlines and extensional faults associated with salt movement. Reservoirs include continental and marine sandstones, limestones and dolostones. Hydrocarbon types are oil, condensate and natural gas. The onshore stratigraphic and structural information can be used to establish a regional geologic framework for the Jurassic for the State coastal waters and adjacent Federal waters areas. Evaluation of the geologic information along with the hydrocarbon data from the tri-state area indicates that at least three Jurassic hydrocarbon trends (oil, oil and gas condensate, and deep natural gas) can be identified onshore. These onshore hydrocarbon trends can be projected into the Mobile area in the Central Gulf of Mexico and into the Pensacola, Destin Dome and Apalachicola areas in the Eastern Gulf of Mexico. Substantial reserves of natural gas are expected to be present in Alabama State waters and the northern portion of the Mobile area. Significant accumulations of oil and gas condensate may be encountered in the Pensacola, Destin Dome, and Apalachicola areas. ?? 1989.

    The UK is dependent on international doctors, with a greater proportion of non-UK qualified doctors working in its universal health care system than in any other European country, except Ireland and Norway. The terms of the UK exit from the European Union can reduce the ability of European Economic Area (EEA) qualified doctors to work in the UK, while new visa requirements will significantly restrict the influx of non-EEA doctors. We aimed to explore the implications of policy restrictions on immigration, by regionally and spatially describing the characteristics of general practitioners (GPs) by region of medical qualification and the characteristics of the populations they serve. This is a cross-sectional study on 37,792 of 41,865 GPs in England, as of 30 September 2016. The study involved age, sex, full-time equivalent (FTE), country and region of qualification and geography (organisational regions) of individual GPs. Additionally at the practice and geography levels, we studied patient list size by age groups, average patient location deprivation, the overall morbidity as measured by the Quality and Outcomes Framework (QOF) and the average payment made to primary care per patient. Non-UK qualified GPs comprised 21.1% of the total numbers of GPs, with the largest percentage observed in East England (29.8%). Compared to UK qualified GPs, EEA and elsewhere qualified GPs had higher FTE (medians were 0.80, 0.89 and 0.93, respectively) and worked in practices with higher median patient location deprivation (18.3, 22.5 and 25.2, respectively). Practices with high percentages of EEA and elsewhere qualified GPs served patients who resided in more deprived areas, had lower GP-to-patient ratios and lower GP-to-cumulative QOF register ratios. A decrease in pay as the percentage of elsewhere qualified GPs increased was observed; a 10% increase in elsewhere qualified GPs was linked to a £1 decrease (95% confidence interval 0.5-1.4) in average pay per patient.

  7. Echelon approach to areas of concern in synoptic regional monitoring

    Myers, Wayne; Patil, Ganapati P.; Joly, Kyle

    1997-01-01

    Echelons provide an objective approach to prospecting for areas of potential concern in synoptic regional monitoring of a surface variable. Echelons can be regarded informally as stacked hill forms. The strategy is to identify regions of the surface which are elevated relative to surroundings (Relative ELEVATIONS or RELEVATIONS). These are areas which would continue to expand as islands with receding (virtual) floodwaters. Levels where islands would merge are critical elevations which delimit echelons in the vertical dimension. Families of echelons consist of surface sectors constituting separate islands for deeper waters that merge as water level declines. Pits which would hold water are disregarded in such a progression, but a complementary analysis of pits is obtained using the surface as a virtual mould to cast a counter-surface (bathymetric analysis). An echelon tree is a family tree of echelons with peaks as terminals and the lowest level as root. An echelon tree thus provides a dendrogram representation of surface topology which enables graph theoretic analysis and comparison of surface structures. Echelon top view maps show echelon cover sectors on the base plane. An echelon table summarizes characteristics of echelons as instances or cases of hill form surface structure. Determination of echelons requires only ordinal strength for the surface variable, and is thus appropriate for environmental indices as well as measurements. Since echelons are inherent in a surface rather than perceptual, they provide a basis for computer-intelligent understanding of surfaces. Echelons are given for broad-scale mammalian species richness in Pennsylvania.

  8. 300 Area signal cable study

    Whattam, J.W.

    1994-01-01

    This report was prepared to discuss the alternatives available for removing the 300 Area overhead signal cable system. This system, installed in 1969, has been used for various monitoring and communication signaling needs throughout the 300 Area. Over the years this cabling system has deteriorated, has been continually reconfigured, and has been poorly documented to the point of nonreliability. The first step was to look at the systems utilizing the overhead signal cable that are still required for operation. Of the ten systems that once operated via the signal cable, only five are still required; the civil defense evacuation alarms, the public address (PA) system, the criticality alarms, the Pacific Northwest Laboratory Facilities Management Control System (FMCS), and the 384 annunciator panel. Of these five, the criticality alarms and the FMCS have been dealt with under other proposals. Therefore, this study focused on the alternatives available for the remaining three systems (evacuation alarms, PA system, and 384 panel) plus the accountability aid phones. Once the systems to be discussed were determined, then three alternatives for providing the signaling pathway were examined for each system: (1) re-wire using underground communication ducts, (2) use the Integrated Voice/Data Telecommunications System (IVDTS) already installed and operated by US West, and (3) use radio control. Each alternative was developed with an estimated cost, advantages, and disadvantages. Finally, a recommendation was provided for the best alternative for each system

    1987-09-01

    The review describes in broad terms the development of regional EM studies during the last five-six years. Large simultaneous magnetometer arrays, broadband and dense profiling with five component instruments, the use of remote reference techniques and in-field data processing have increased both the number and the quality of EM surveys. The increase has been strong all over the world. An extensive list of references, divided geographically, is presented. Selected examples of regional resisitivity-versus-depth curves are shown for Africa, the Baikal region, the Baltic Shield, the Canadian Shield, the Carpathian regions, the Central Andes, Iceland, India, the Juan de Fuca Plate, the Münsterland Basin, the Rio Grande rift, the Scottish Caledonides, the Tasman Sea, and for the United States in general. Because of the influence of tectonic settings and the metamorphic grade of rocks, only qualitative aspects of the results are relevant. ‘Classical’ array studies, especially in Australia, in the Carpathian regions, in India, in North Germany and in Scotland have been reinterpreted and completed with more accurate 2D modelling and dense MT profiling. In the USA and Canada also new regions have been surveyed extensively. New regional EM work has been conducted extensively on the Baltic Shield and in Central and North Africa, Siberia, China, in the areas around the Caspian and Black Seas and in South America. The newest studies are supported by or compared with other geophysical data, which also are used in extrapolating for missing EM data density. There are several successful large-scale projects in operation: the European Geotraverse (EGT), the KAPG International Geotraverses and the EMSLAB project (with its first preliminary results). Regional EM studies have been increasingly applied to geothermal, hydrocarbon and mineral prospecting as well as local structural studies, e.g. studies of sites for nuclear waste disposal.

    The hydrogeologic study covers an area of 50 km 2 with the objectives of to determine the possibility of use of the underground waters and to locate places to carry out exploratory perforations in lands of Cafam, equally the elaboration of a hydrogeologic map of the region; for the effect it was carried out cartography geologic scale 1:10.000, inventory and sampling of water point, geoelectric prospecting and some permeability tests. In the area the exploitation of underground water is incipient, alone there are 20 points of water, of which none produce more than 1L/seg. The water has in general good physical chemistry quality for the human consumption. Geologically was recognized the groups Guadalupe and Gualanday, also some quaternary deposits; the previous ones were subdivided in 11 geological units for its composition and morphology, which are framed structurally in the E flank of the synclinal of Carmen de Apicala and displaced by traverse faults with address E-W and N-W. From the point of hydrogeologic view the units were grouped in 8 aquifer systems, of which four are considered of hydrogeologic importance for the area; the sector with better possibilities to capture these aquifer systems is the W of the area (in the terraces area) that extends to the Sumapaz River. For the Cafam sector a place was selected to build an exploratory well of 200 mts. of depth that would capture an aquifer of low transmissivity, corresponding to the Unit T3

  14. Is the planum temporale surface area a marker of hemispheric or regional language lateralization?

    2018-04-01

    We investigated the association between the left planum temporale (PT) surface area or asymmetry and the hemispheric or regional functional asymmetries during language production and perception tasks in 287 healthy adults (BIL&GIN) who were matched for sex and handedness. The measurements of the PT surface area were performed after manually delineating the region using brain magnetic resonance images (MRI) and considering the Heschl's gyrus (HG) duplication pattern; the measurements either included (PT tot ) or did not include (PT post ) the second gyrus. A region encompassing both the PT and HG (HGPT) was also studied. Regardless of the ROI measured, 80% of the sample had a positive left minus right PT asymmetry. We first tested whether the PT tot , PT post and HGPT surface areas in the left or right hemispheres or PT asymmetries differed in groups of individuals varying in language lateralization by assessing their hemispheric index during a sentence production minus word list production task. We then investigated the association between these different measures of the PT anatomy and the regional asymmetries measured during the task. Regardless of the anatomical definition used, we observed no correlations between the left surface areas or asymmetries and the hemispheric or regional functional asymmetries during the language production task. We then performed a similar analysis using the same sample measuring language functional lateralization during speech listening tasks (i.e., listening to sentences and lists of words). Although the hemispheric lateralization during speech listening was not correlated with the left PT tot , PT post or HGPT surface areas or the PT asymmetries, significant positive correlations were observed between the asymmetries in these regions and the regional functional asymmetries measured in areas adjacent to the end of the Sylvian fissure while participants listened to the word lists or sentences. The PT asymmetry thus appears to be

    2014-12-01

    Full Text Available The article explores the potential of an integrative approach to ethnohistoric reconstruction. Using both onomastic and archaeological data, the author makes an attempt to reveal the correlations between the substrate toponymy of the Middle Oka Region and the areas of the archaeological cultures found on this territory. The results of the research show that the main types of non-Slavic place names of the region correlate with some important archaeological cultures: Fatyanovo-Balanovo culture, Shagar culture, Gorodets culture, cultures of Merya, Muroma, Meshchera and Mordva. Taking into account the most recent etymologies, the paper provides a toponymic stratigraphy of the territory in the remotest periods: Neolithic Era, Bronze Age and early Iron Age. The author argues that the formation of the basic hydronymic systems of the Middle Oka Region may be dated to the Bronze Age and reliably ascribed to the regional corded ware and battle axe cultures (Fatyanovo-Balanovo, Shagar whilst the formation of the basic toponymic areas of the North-Eastern part of the region may be attributed to a later period (late 1st — early 2nd millennium AD. The article points out that the toponymic data are crucial for the ethnocultural attribution of the population of the settlements poorly studied by archaeologists. They acquire a particular importance when the interpretation of archaeological materials is disputable or insufficient.

    2010-01-01

    Because of the hydrogeological complexity, traditional thinking of aquifer characteristics is not appropriate for groundwater system in Beishan area. Uncertainty analysis of groundwater models is needed to examine the hydrologic effects of spatial heterogeneity. In this study, fast Fourier transform spectral method (FFTS) was used to generate the random horizontal permeability parameters. Depth decay and vertical anisotropy of hydraulic conductivity were included to build random permeability models. Based on high-performance computers, hundreds of groundwater flow models were simulated. Through stochastic simulations, the effect of heterogeneity to groundwater flow pattern was analyzed.

    2014-01-01

    Rapid urbanization has caused land use transformation and encroachment of built environment into arable agriculture land. Uncontrolled expansion could bring negative impacts to society, space and the environment. Therefore, information on expansion and future spatial pattern of built-up areas would be useful for planners and decision makers in formulating policies towards managing and planning for sustainable urban development. This study demonstrates the usage of Geographic Information System in monitoring the expansion of built-up area in Seberang Perai region, Penang State, Malaysia. Built-up area has increased by approximately 20% between 1990 and 2001 and further increased by 12% between 2001 and 2007. New development is expected to continue encroach into existing open space and agriculture area since those are the only available land in this study area. The information on statistics of the expansion of built-up area and future spatial pattern of urban expansion were useful in planning and managing urban spatial growth

    Full Text Available Our study objectives were to determine bat species composition and to study the genetic variations and sound characteristics in bats of the Kharaa, Shatan, and Ulgii areas of Mongolia. This study is the first bat survey in this area. Nineteen species were from Mongolia. Six bat species belonged to three genera. We performed mitochondrial DNA sequencing of Myotis bombinus, Myotis gracilis, and Myotis petax to confirm the morphological identification of these species. We also determined the sound frequencies of the six bat species, based on their echolocation calls. The conservation status was determined using World Conservation Union red list categories and criteria. Sixteen bats from three species were ringed during this study and three artificial boxes were placed on trees in the Kharaa River Valley. Other than the northern bat, all species were eastern Palearctic. The northern bat (Eptesicus nilssonii species is widespread in the northern Palearctic region.

    Full Text Available Objective: Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA can cause bacterial skin infections that are common problems for Aboriginal children in New South Wales (NSW. MRSA is not notifiable in NSW and surveillance data describing incidence and prevalence are not routinely collected. The study aims to describe the epidemiology of CA-MRSA in Aboriginal children in the Hunter New England Local Health District (HNELHD. Methods: We linked data from Pathology North Laboratory Management System (AUSLAB and the HNELHD patient administration system from 33 hospital emergency departments. Data from 2008–2014 for CA-MRSA isolates were extracted. Demographic characteristics included age, gender, Aboriginality, rurality and seasonality. Results: Of the 1222 individuals in this study, 408 (33.4% were Aboriginal people. Aboriginal people were younger with 45.8% aged less than 10 years compared to 25.9% of non-Aboriginal people. Most isolates came from Aboriginal people who attended the regional Tamworth Hospital (193/511 isolates from 149 people. A larger proportion of Aboriginal people, compared to non-Aboriginal people, resided in outer regional (64.9% vs 37.2% or remote/very remote areas (2.5% vs 0.5%. Most infections occurred in summer and early autumn. For Aboriginal patients, there was a downward trend through autumn, continuing through winter and spring. Discussion: Aboriginal people at HNELHD emergency departments appear to represent a greater proportion of people with skin infections with CA-MRSA than non-Aboriginal people. CA-MRSA is not notifiable in NSW; however, pathology and hospital data are available and can provide valuable indicative data to health districts for planning and policy development.

    Three different systems of designating protected areas in a Mediterranean region in southeastern Spain were studied, referring to their effectiveness and efficiency for protecting both the breeding territories and the suitable habitat of a set of ten raptor species. Taking into consideration the varying degrees of endangerment of these species, a map of multispecies conservation values was also drawn up and superimposed on the three protected-area systems studied. In order to compare the levels of protection afforded by the three systems, we considered two indices that measured their relative effectiveness and efficiency. The effectiveness estimated the proportion of territories or optimal habitat protected by the networks while efficiency implicitly considered the area of each system (percentage of breeding territories or optimal habitat protected per 1% of land protected). Overall, our results showed that the most efficient system was that formed by the set of regional parks and reserves (17 protected breeding territories per 100 km²), although, given its small total area, it was by far the least effective (only protecting the 21% of the breeding territories of all species and 17% of the area of high conservation value). The systems formed by the Special Protection Areas (designated under the EU "Birds Directive") and by the Special Conservation Areas (designated under the EU "Habitats Directive") notably increased the percentages of protected territories of all species (61%) and area of high conservation value (57%), but their efficiency was not as high as expected in most cases. The overall level of protection was high for all species except for the Lesser Kestrel (Falco naumanni), an endangered falcon that inhabits pseudo-steppe and traditional agricultural habitats, which are clearly underrepresented in the protected-area network of the study region.

    Full Text Available This study investigates the spatial economic structure and inequality in Thailand at the national and regional levels, with a particular focus on the Northeastern region in the period from 1987 to 2007. The study has three main points: 1 examination of the economic structure and inequality at the national level and in the Northeastern region according to the Theil index, 2 determination of regional growth centres and satellite towns by using growth pole theory as a conceptual framework and incorporating spatial interaction analysis and 3 analysis of the relationship between regional growth centres and satellite towns with regard to the impact on growth and inequality. The results show that the Northeastern region is definitely the lagging region in the nation, by both gross domestic product (GDP and gross regional product (GRP per capita. It was therefore selected for a case study. Spatial analysis identified Nakhon Ratchasima, Khon Kaen, Udon Thani and Ubon Ratchathani as regional growth centres. Each of them has its own sphere of influence (or satellite towns, and the total area of regional growth centres and satellite towns are classified as sub-regions. The development of regional growth centres has a direct impact on sub-regional economic growth through economic and social relationships: urbanisation, industrial development, per capita growth, the number of higher educational institutes and so on. However, such growth negatively correlates with economic equality among the provinces in a sub-region. The inequality trend is obviously on an upswing. This study suggests that industrial links between regional growth centres and their satellite towns should be improved in order for regional growth centre development to have a consistently desirable effect on both economic growth and equality. Such a strong process means that the growth of regional growth centres will spread, leading to the development of their surrounding areas.

    1983-01-01

    Analyses of regional gravity and magnetic anomaly maps have been carried out to assist in the evaluation of the Gibson Dome area as a possible repository site for high-level radioactive waste. Derivative, wavelength-filtered, and trend maps were compiled to aid in properly locating major geophysical trends corresponding to faults, folds, and lithologic boundaries. The anomaly maps indicate that Paradox Basin is characterized by a heterogeneous Precambrian basement, essentially a metamorphic complex of gneisses and schist intruded by granitic rocks and mafic to ultramafic bodies. Interpreted Precambrian structures trend predominantly northwest and northeast although east-west trending features are evident. Prominent gravity lows define the salt anticlines. Structural and lithologic trends in the Gibson Dome area are closely examined. Of greatest interest is a series of circular magnetic highs trending west-northwest into the Gibson Dome area. Further study of the exact definition and geologic significance of this series of anomalies is warranted.

    Full Text Available For the most effective and efficient management of certain natural resources (e.g. protected areas and disasters (e.g. wildfires transboundary approaches are needed. In addition in the management of protected areas, the role of wildfire should be incorporated, something that was ignored in the past and led to catastrophic wildfires. The Black Sea is a region that wildfires in the protected areas are expected to increase. This has to do with the abandonment of rural areas and the higher temperatures, especially during summer, due to climate change. Interesting is also the fact that some countries of the region have extensive experience while other do not have neither the experience nor the necessary infrastructures to face large wildfires. A transboundary collaboration would be very beneficial to the countries with limited experiences and capacities to suppress wildfires. The objective of this study is to be proactive by developing innovative tools to help suppress wildfires and enhancing the knowledge on wildfires and protected areas. The innovative tools included 4 different research activities and products. Firstly, an online Digital Geodatabase for the six pilot areas was developed. Next forest fire fuels and maps were developed while a forest fire behavior model was run to create the overall fire risk maps for the pilot areas. To estimate water resources and watershed streamflows the hydrologic model SWAT was validated and calibrated for the pilot areas. The final activities included a multi-criteria decision analysis to select the optimal location of the water reservoirs and the use of spatial analyst to provide the optimal routes to reach reservoirs by the fire vehicles. To enhance the responsible agency personnel along with stakeholders knowledge of the region, a Neighborhood Network with regular quarterly meetings was established. Participants for all six project countries were present in the meetings. Overall, new tool that will enhance

    A water balance or budget is developed as an accounting of the components of a closed hydrologic system. In the WIPP study area, water-budget techniques have previously been used to compute leakage from Lake Avalon and from potash refinery spoil ponds. A general expression for a closed hydrologic system is presented. In a developed area like the WIPP region, the water budget must include many usage factors, such as municipal or industrial pumpage. In the WIPP water-budget study area, inflows are precipitation, surface- and ground-water inflow, and the artificial addition of surface and ground water. Outflows are surface runoff, evaporation and transpiration, and ground-water outflow. Changes in storage in the WIPP region have also been documented. The WIPP water balance described here is based on a combination of long-term averages and figures for 1980. 12 refs., 5 figs., 1 tab

In general, we can distinguish four types of regions, formed to implement the tasks under different direction: a homogeneous regions (formed on the basis of common characteristics – mountain region, economically developed / underdeveloped region and so on.. b functional regions (formed by determining the basic type of economic activity – touristic region, agricultural region, etc.. c administrative regions (formed by pre-defined criteria for performing administrative functions in a particular area – district, local council, etc.. d personal perception regions (based on personal values – Homeland and so on.. The focus of this publication focuses on the study of rural regions. As a result of studies is found that the population of Ukraine decreased by about 7 million Inhabitants. In 1993 there was 52.2 million of people, and in 2016 dropped to 42.7 million (temporary occupied territories excluded. Determined that the most influential factors are the degradation of rural region’s economic and demographic crisis (can be both a cause and consequence of each other. In this regard, the worsening of demographic situation is the biggest problem, because without human resources economic growth can’t be achieved. For more profound understanding of the problem we used the spiral of negative developed of communities/regions proposed by Austrian scientists G. Weber and T. Fisher. It indicates the relationship between adverse events and their sequence. This choice is not accidental, because the spiral indicates that this is a progressive movement that eventually accelerated and the difficulty of stopping the negative processes increases not arithmetically but geometrically. Therefore, developing regional programs of rural development moderators (selected and trained specialists who work in the region cooperate with the heads of communities and local residents

    Full Text Available Using a high-resolution regional climate model coupled with urban canopy model, the present study provides the first attempt in quantifying the impact of metropolitan-scale urban planning scenarios on moist thermal environment under global warming. Tokyo metropolitan area is selected as a test case. Three urban planning scenarios are considered: status quo, dispersed city, and compact city. Their impact on the moist thermal environment is assessed using wet-bulb globe temperature (WBGT. Future projections for the 2070s show a 2–4°C increase in daytime mean WBGT relative to the current climate. The urban scenario impacts are shown to be small, with a −0.4 to +0.4°C range. Relative changes in temperature and humidity as the result of a given urban scenario are shown to be critical in determining the sign of the WBGT changes; however, such changes are not necessarily determined by local changes in urban land surface parameters. These findings indicate that urban land surface changes may improve or worsen the local moist thermal environment and that metropolitan-scale urban planning is inefficient in mitigating heat-related health risks for mature cities like Tokyo.

    With the rapid economic development and the growth of population happening in the urban historical and cultural areas, heritage and historical buildings along with their natural and artificial surrounding environments are suffering constructive destruction. Due to the lack of precise partition of protection region and construction control region in the local cultural relics protection law, traditional regional conservation planning cannot engaged with the urban controllability detailed planning very well. According to the several protection regulations about heritage and historical buildings from latest laws, we choose Baxian Temple area to study on the improvments of traditional regional conservation planning. The technical methods of this study mainly rely on GIS, which can complete the fundamental work of each stage. With the analytic hierarchy process(AHP), the comprehensive architectural value assessments can be calculated according to the investigation results. Based on the calculation results and visual corridor analysis, the precise range of protection region and construction control region can be decided and the specific protection measures can be formulated.

  13. Applicability of `GREATEM' system in mapping geothermal regions in volcanic areas

    The ‘GREATEM’ helicopter borne TEM system employs a long grounded cable as transmitter while a light weight receiver coil is flown below a helicopter. This arrangement greatly simplifies the flying logistics and speed of the survey. Also there is very little reduction in the anomaly amplitude when the survey altitude is increased. This is a great advantage particularly in volcanic regions usually having rough topography, as the ‘GREATEM’ survey can be done with helicopter flying at a safe height. Many volcanic areas have anomalous geothermal regions containing hydrothermal fluids. Eruption of volcanoes may cause changes in the thermal character and spatial distribution of these regions. Mapping of these regions is important as they may be associated with hazards. Sometimes, if the temperature is high and volume of the geothermal region is large, they can provide a good source of geothermal energy. Applicability of ‘GREATEM’ system in mapping geothermal regions in volcanic areas is studied by numerical modeling. We have considered a 3D conductor at a shallow depth (50 t0 100m), representing the anomalous geothermal region with dimensions of 500m X 500m X 500m. Different types of geological host environment are considered by varying their resistivities from 10 Ohm.m to 2000 Ohm.m. The ‘GREATEM’ response is analyzed as ‘Percentage Difference (PD)’ over the response produced by the host environment. It is found that the “GREATEM’ system can delineate the geothermal region well. Many geothermal regions are associated with a deeper (> 1 km) reservoir of much larger dimensions. In this situation also it is found that the ‘GREATEM’ system can pick up the response of the shallower geothermal region against the background response of different types of geological host environment containing the deeper reservoir (Figure 1).

    Full Text Available The issue of regionalism particularly in the matter of preferential trade area is not an old fashion debate, but it becomes a prominent feature and a popular tool for global trading system. However, it does not mean that the regionalism might always bring benefit for any actor especially in terms of every national interest in the region. This paper would elaborate the effect of preferential trade area (PTAs establishment on the economic interest of ASEAN countries member. Through literature study, this paper concludes that the PTAs produce many positive benefits for the ASEAN countries member. The flexibility of partnerships and coverage selection under PTAs has helped ASEAN solve the crisis and increase efficiency as well as stimulate the main goal of global fair trade by expanding economic linkages. Thus, it could be said that PTAs enhance the multilateralism under the WTO system

    1999-07-01

    The Regional Sustainable Development Strategy (RSDS) provides a framework for balancing development with environmental protection. This provisional direction for sustainable resource management was confirmed in a March 1999 policy document. It is as follows: the use of Alberta's natural resources shall be sustainable, the management of Alberta's natural resources shall support and promote the Alberta economy, Alberta's environment shall be protected, resources shall be managed on an integrated basis, and Alberta's natural resources shall be managed for multiple benefits. The focus of the RSDS is to address the need to balance resource development and environmental protection. The report covers: an overview, the Regional Sustainable Development Strategy and the RSDS management model. Blueprints for action concerning the impacts of oilsands development are provided under 14 themes, including 1) cumulative impacts on wildlife, fish habitat and populations, surface and groundwater quality and 2) human health effects of air emissions and effects of air emissions on wildlife and vegetation. The RSDS will apply provincial and federal policy, legislation, standards and programs in a regional context, including principles in the Canadian Council of Ministers of the Environment (CCME) Harmonization Accord

  17. Mapping regional patterns of large forest fires in Wildland-Urban Interface areas in Europe.

    2016-05-01

    Over recent decades, Land Use and Cover Change (LUCC) trends in many regions of Europe have reconfigured the landscape structures around many urban areas. In these areas, the proximity to landscape elements with high forest fuels has increased the fire risk to people and property. These Wildland-Urban Interface areas (WUI) can be defined as landscapes where anthropogenic urban land use and forest fuel mass come into contact. Mapping their extent is needed to prioritize fire risk control and inform local forest fire risk management strategies. This study proposes a method to map the extent and spatial patterns of the European WUI areas at continental scale. Using the European map of WUI areas, the hypothesis is tested that the distance from the nearest WUI area is related to the forest fire probability. Statistical relationships between the distance from the nearest WUI area, and large forest fire incidents from satellite remote sensing were subsequently modelled by logistic regression analysis. The first European scale map of the WUI extent and locations is presented. Country-specific positive and negative relationships of large fires and the proximity to the nearest WUI area are found. A regional-scale analysis shows a strong influence of the WUI zones on large fires in parts of the Mediterranean regions. Results indicate that the probability of large burned surfaces increases with diminishing WUI distance in touristic regions like Sardinia, Provence-Alpes-Côte d'Azur, or in regions with a strong peri-urban component as Catalunya, Comunidad de Madrid, Comunidad Valenciana. For the above regions, probability curves of large burned surfaces show statistical relationships (ROC value > 0.5) inside a 5000 m buffer of the nearest WUI. Wise land management can provide a valuable ecosystem service of fire risk reduction that is currently not explicitly included in ecosystem service valuations. The results re-emphasise the importance of including this ecosystem service

    Principal findings of this study that are pertinent to an assessment of suitability of the hydrogeologic systems to store and contain radioactive waste in salt anticlines of adjacent areas are: water in the upper ground-water flow system discharges to the San Juan River - a major tributary of the Colorado River. Discharge of water from the upper aquifer system to streambed channels of the San Juan River and its tributaries during low-flow periods primarily is through evapotranspiration from areas on flood plains and maintenance of streamflow; the lower ground-water system does not have known recharge or discharge areas within the study area; subsurface inflow to this system comes from recharge areas located north and northeast of the study area; the upper and lower ground-water systems are separated regionally by thick salt deposits in the Blanding-Durango study area of the Paradox basin; potential exists in mountainous areas for downward leakage between the upper and lower ground-water systems, where salt deposits are thin, absent, or faulted; no brines were found in this study area with outflow to the biosphere; water in the upper ground-water system generally is fresh. Water in the lower ground-water system generally is brackish or saline; and ground-water flow disruptions by contiguous faults probably are common in the upper ground-water system. These disruptions of flow are not apparent in the lower ground-water system, perhaps because available hydrologic data for the lower ground-water system are scarce. The above major findings do not preclude the potential for waste storage in salt; however, they do not allow the prediction of detailed ground-water flow rates and directions through this area. 55 references, 13 figures, 15 tables

    On the base of the study in the working area, a conclusion is made that there are 36 combined types of tectonic-material and 6 basic tectonic units. According to radioactive geochemical quantitative and qualitative factors, which are relevant to rock composition and geological formation, 5 radioactive geochemical provinces and 8 radioactive geochemical differentiation regions could be marked out. The working area contains three hydrogeological fold belts and two hydrogeological artesian basins. It could also be divided into 9 metallogenetic provinces or 30 metallogenetic regions, or 206 ore districts. On the other hand, the area could be divided into 2 uranium metallogenetic provinces, 2 potential uranium metallogenetic provinces and 3 uraniferous provinces, which contain uranium properties or potential uranium properties or uraniferous properties. The authors systematically summary the geological environment and indicators of prospecting and predicting of fluorine-molybdenum-uranium formation, hydromorphic uranium deposit formation and poly-genetic uranium deposit formation which contains uranium-coal model, uranium-asphalt model, uranium-sulfuret model, etc. The metallogenetic potential among Aerdan uranium province, Aoliaokema uranium province, Bulieya-Jiamusi-Xingkai potential uranium province and Xihuote-Alin uranium province are assessed. On this base, the authors delineate 23 uranium metallogenetic prospective areas needing further exploration efforts. 8 uranium metallogenetic prospective areas in China are marked out, which are areas of interest for searching for exogenetic and epigenetic sandstone uranium deposits

    To estimate consumption of five subgroups of antihypertensive drugs by primary care areas and to analyze its variation. We performed an ecological, descriptive study of antihypertensive consumption in 239 primary care areas in the autonomous region of Valencia in 2005 followed by analysis of the variability observed. The 239 primary care areas were studied by descriptive analysis of dispensation [defined daily dose (DDD) per 1,000 inhabitants/day in pensioners (DDD/1000p/day) and in the active population (DDD/1000a/day)] and standardized consumption ratios. Small-area variation analysis was used to analyze the observed variability. Associations among dispensations of the distinct therapeutic subgroups were also analyzed. Overall antihypertensive use in the autonomous region of Valencia in 2005 was 235.6DDD/1000/day. This consumption was concentrated in pensioners (800DDD/1000p/day vs. 73DDD/1000a/day). Consumption of antihypertensive subgroups oscillated from 442DDD/1000p/day for drugs with action on the renin-angiotensin system to 32DDD/1000p/day for doxazosin. The active population showed similar patterns. Variation in consumption was moderate, with coefficients of variation from 0.20 to 0.40 (slightly greater for the active population). Associations among dispensations of the different therapeutic subgroups were strong. This study shows major variations in the overall consumption of antihypertensive drugs among primary care areas of the autonomous region of Valencia. These results suggest that variation may be associated with problems of underutilization in areas with lower consumption. Copyright © 2010 SESPAS. Published by Elsevier Espana. All rights reserved.

    This study explored the relationship between global left ventricular ejection fraction (LVEF), regional LVEF of infarct myocardium, and the viability of the myocardium due to the development of collaterals in the infarct area. Each was evaluated by exercise thallium-201 myocardial SPECT, multigated blood pool scintigraphy and coronary angiography. A total of 68 patients with old anteroseptal myocardial infarction and 23 normal persons were studied. The patients were found to have septal defect on exercise thallium images. According to the appearance of redistribution (RD) on delayed images, the patients were classified as having positive RD (n=42, 62%) or negative RD (n=26, 38%). The global LVEF was compared with regional LVEF of the basal, middle and apical areas within septum, as calculated by multigated blood pool scintigraphy. There was no significant difference in global LVEF between the groups of positive and negative RD patients. However, regional LVEF of the basal and middle areas was significantly larger in the group of positive RD than the group of negative RD. Collaterals were significantly observed in the group of positive RD, as compared with the group of negative RD (53% vs 25%). It was more frequent in cases of higher degree of stenosis. In the group of negative RD, none of the patients had collaterals when coronary stenosis was 90% or less. Redistribution may reflect myocardial viability. Myocardial viability within the infarct area had favorable influences on the regional left ventricular function. Therefore, not only global but also regional left ventricular function is necessary for better understanding of pathophysiology of myocardial infarction.(N.K.)

    By the methods of in situ investigation and regional ecological planning, the present ecological environment, ecosystem vulnerability, and ecological environment sensitivity in "Ji Triangle" Region were analyzed, and the ecological network of the study area was constructed. According to the ecological resources abundance degree, ecological recovery, farmland windbreak system, environmental carrying capacity, forestry foundation, and ecosystem integrity, the study area was classified into three regional ecological function ecosystems, i. e., east low hill ecosystem, middle plain ecosystem, and west plain wetland ecosystem. On the basis of marking regional ecological nodes, the regional ecological corridor (Haerbin-Dalian regional axis, Changchun-Jilin, Changchun-Songyuan, Jilin-Songyuan, Jilin-Siping, and Songyuan-Siping transportation corridor) and regional ecological network (one ring, three links, and three belts) were constructed. Taking the requests of regional ecological security into consideration, the ecological environment security system of "Ji Triangle" Region, including regional ecological conservation district, regional ecological restored district, and regional ecological management district, was built.

    Autologous stem cell transplantation is still considered the standard of care in young patients with multiple myeloma (MM). This disease is the most common indication for high-dose therapy (HDT) supported by hematopoietic stem cell transplantation and much data support the benefit of this procedure. Results of randomized studies are in favor of tandem autologous transplantation although the effect on overall survival is unclear. Based on sequential registration trials in the Nordic area, we aimed to evaluate the outcome of conventional single or double HDT. During 1994–2000 we registered a total of 484 previously untreated patients under the age of 60 years at diagnosis who on a regional basis initially were treated with single [Trial NMSG #5/94 and #7/98 (N=383)] or double [Trial Huddinge Karolinska Turku Herlev (N=101)] high-dose melphalan (200 mg/m2) therapy supported by autologous stem cell transplantation. A complete or very good partial response was achieved by 40% of patients in the single transplant group and 60% of patients in the double transplant group (p=0.0006). The probability of surviving progression free for five years after the diagnosis was 25% (95% CL 18–32%) in the singletransplant group and 46% (95% CL 33–55%) in the double transplant group (p=0.0014). The estimated overall five-year survival rate was 60% in the single transplant group and 64% in the doubletransplant (p=0.9). In a multivariate analysis of variables, including single versus double transplantation, β2 microglobulin level, age, sex and disease stage, only β2 microglobulin level was predictive for overall survival (p>0.0001) and progression free survival (p=0.001). In accordance with these results, a 1:1 case-control matched comparison between double and single transplantation did not identify significant differences in overall and progression free survival. In this retrospective analysis up front double transplantation with melphalan (200 mg/m2) as compared to single

    We used landslide information for 13 study areas in Italy and morphometric information obtained from the 3-arcseconds shuttle radar topography mission digital elevation model (SRTM DEM) to determine areas where landslide susceptibility is expected to be negligible in Italy and in the landmasses surrounding the Mediterranean Sea. The morphometric information consisted of the local terrain slope which was computed in a square 3 × 3-cell moving window, and in the regional relative relief computed in a circular 15 × 15-cell moving window. We tested three different models to classify the "non-susceptible" landslide areas, including a linear model (LNR), a quantile linear model (QLR), and a quantile, non-linear model (QNL). We tested the performance of the three models using independent landslide information presented by the Italian Landslide Inventory (Inventario Fenomeni Franosi in Italia - IFFI). Best results were obtained using the QNL model. The corresponding zonation of non-susceptible landslide areas was intersected in a geographic information system (GIS) with geographical census data for Italy. The result determined that 57.5% of the population of Italy (in 2001) was located in areas where landslide susceptibility is expected to be negligible. We applied the QNL model to the landmasses surrounding the Mediterranean Sea, and we tested the synoptic non-susceptibility zonation using independent landslide information for three study areas in Spain. Results showed that the QNL model was capable of determining where landslide susceptibility is expected to be negligible in the validation areas in Spain. We expect our results to be applicable in similar study areas, facilitating the identification of non-susceptible landslide areas, at the synoptic scale.

    Full Text Available BACKGROUND: In this study, we aim to identify key climatic factors that are associated with the transmission of Japanese encephalitis virus in areas located near the Three Gorges Dam, between 1997 and 2008. METHODS: We identified three geographical regions of Chongqing, based on their distance from the Three Gorges Dam. Collectively, the three regions consisted of 12 districts from which study information was collected. Zero-Inflated Poisson Regression models were run to identify key climatic factors of the transmission of Japanese encephalitis virus for both the whole study area and for each individual region; linear regression models were conducted to examine the fluctuation of climatic variables over time during the construction of the Three Gorges Dam. RESULTS: Between 1997 and 2008, the incidence of Japanese encephalitis decreased throughout the entire city of Chongqing, with noticeable variations taking place in 2000, 2001 and 2006. The eastern region, which is closest to the Three Gorges Dam, suffered the highest incidence of Japanese encephalitis, while the western region experienced the lowest incidence. Linear regression models revealed that there were seasonal fluctuations of climatic variables during this period. Zero-Inflated Poisson Regression models indicated a significant positive association between temperature (with a lag of 1 and 3 months and Japanese encephalitis incidence, and a significant negative association between rainfall (with a lag of 0 and 4 months and Japanese encephalitis incidence. CONCLUSION: The spatial and temporal trends of Japanese encephalitis incidence that occurred in the City of Chongqing were associated with temperature and rainfall. Seasonal fluctuations of climatic variables during this period were also observed. Additional studies that focus on long-term data collection are needed to validate the findings of this study and to further explore the effects of the Three Gorges Dam on Japanese

    The purpose of this study were to determine characteristics and environmental carrying capacities of coastal area in Yogyakarta Special Region for aquaculture. This study was conducted in 2015 by characterizing land and water dynamics, land use, and the suitability of coastal environments for aquaculture. Evaluation on the coastal environments suitability for aquaculture ponds was based on the landforms, soil properties, water quality and land. Selection of coastal locations for aquaculture development was based on the level of suitability of coastal environment. The results showed that the coastal in Kulon Progo and Bantul Regencies were characterized by sand dune and beach ridge with sandy soil texture, while in Gunungkidul Regency was characterized by limestone hill with rocky texture. Water sources of the coastal area were the sea, river, and ground water with the salinity of 31–37, 7–11, 7–31 ppt and pH of 7.4–8.4 7.0–8.2 and 7.4–9.9, respectively. The coastal lands were used for seasonal/annual planting, ponds, fish landing sites, tourism areas and conservation areas. The coastal carrying capacity was rather suitable for aquaculture, especially in the sandy soil area. Aquaculture in that area can be done intensively for shrimp (Litopenaeus vannamei), using biocrete (biological material) or plastic sheet.

    Basal ganglia have complex functional connections with the cerebral cortex and are involved in motor control, executive functions of the forebrain, such as the planning of movement, and cognitive behaviors based on their connections. The aim of this study was to provide detailed functional correlation patterns between the basal ganglia and cerebral cortex by conducting an inter regional correlation analysis of the {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography (PET) data based on precise structural information. Fifteen participants were scanned with 7-Tesla magnetic resonance imaging (MRI) and high resolution research tomography (HRRT)-PET fusion system using {sup 18}F-FDG. For detailed inter regional correlation analysis, 24 subregions of the basal ganglia including pre-commissural dorsal caudate, post-commissural caudate, pre-commissural dorsal putamen, post-commissural putamen, internal globus pallidus, and external globus pallidus and 80 cerebral regions were selected as regions of interest on the MRI image and their glucose metabolism were calculated from the PET images. Pearson's product-moment correlation analysis was conducted for the inter regional correlation analysis of the basal ganglia. Functional correlation patterns between the basal ganglia and cerebral cortex were not only consistent with the findings of previous studies, but also showed new functional correlation between the dorsal striatum (i.e., caudate nucleus and putamen) and insula. In this study, we established the detailed basal ganglia subregional functional correlation patterns using {sup 18}F-FDG PET/MRI fusion imaging. Our methods and results could potentially be an important resource for investigating basal ganglia dysfunction as well as for conducting functional studies in the context of movement and psychiatric disorders.

    Indus Deltaic Region (IDR) in Pakistan is an erosion vulnerable coast due to the high deep water wave energy. Livelihood of millions of people depends on the fisheries and mangrove forests in IDR. IDR consists of many creeks where Daboo is a major creek located at southeast of the largest city of Pakistan, Karachi. Unfortunately, there has been no detailed study to analyze the damages of sea water intrusion at a large temporal and spatial scale. Therefore, this study is designed to estimate the effects of sea water inundation based on changing sea water surface salinity and sea surface temperature (SST). Sea surface salinity and SST data from two different surveys in Daboo creek during 1986 and 2010 are analyzed to estimate the damages and extent of sea water intrusion. Mean salinity has increased 33.33% whereas mean SST decreased 13.79% from 1987 to 2010. Spatio-temporal analysis of creek area using LANDSAT 5 Thematic mapper (TM) data for the years 1987 and 2010 shows significant amount of erosion at macro scale. Creek area has increased approximately 9.93% (260.86 m2 per year) which is roughly equal to 60 extensive sized shrimp farms. Further Land Use Land Cover (LULC) analyses for years 2001 and 2014 using LANDSAT 7 Enhanced Thematic Mapper Plus (ETM+) has indicated 42.3% decrease in cultivated land. Wet mud flats have spread out at the inner mouth of creek with enormous increase of 123.3%. Significant sea water intrusion has increased the area of barren land by 37.9%. This also resulted in overall decrease of 6.7% in area covered by mangroves. Therefore, this study recorded a significant evidence of sea water intrusion in IDR that has caused serious damages to community living in the area, economical losses. Additionally, it has also changed the environment by reducing creek biological productivity as reported by earlier studies over other regions of the world.

  16. Regional urban area extraction using DMSP-OLS data and MODIS data

    Zhang, X Y; Cai, C; Li, P J

    2014-01-01

    Stable night lights data from Defense Meteorological Satellite Program (DMSP) Operational Line-scan System (OLS) provide a unique proxy for anthropogenic development. This paper proposed two new methods of extracting regional urban extents using DMSP-OLS data, MODIS NDVI data and Land Surface Temperature (LST) data. MODIS NDVI data were used to reduce the over-glow effect, since urban areas generally have lower vegetation index values than the surrounding areas (e.g. agricultural and forest areas). On the other hand, urban areas generally show higher surface temperatures than the surrounding areas. Since urban area is the only class of interest, a one-class classifier, the One-Class Support Vector Machine (OCSVM), was selected as the classifier. The first method is classification of different data combinations for mapping: (1) OLS data and NDVI data, (2) OLS data and LST data, and (3) OLS data, NDVI data and LST data combined. The second one is a morphological reconstruction based method which combines classification results from OLS plus NDVI data and from OLS plus LST data. In the morphological reconstruction based method, the classification result using OLS and NDVI data was used as a mask image, while the classification result using OLS and LST data was used as a marker image. The north China area covering 14 provinces was selected as study area. Classification results from Landsat TM/ETM+ data from selected areas with different development levels were used as reference data to validate the proposed methods. The results show that the proposed methods effectively reduced the over-glow effect caused by DSMP-OLS data and achieved better results compared to the results from the traditional thresholding technique. The combination of all three datasets produces more accurate results than those of using any two datasets. The proposed morphological reconstruction based method achieves the best result in urban extent mapping

  17. A remote sensing method for estimating regional reservoir area and evaporative loss

    2017-12-01

    Evaporation from the water surface of a reservoir can significantly affect its function of ensuring the availability and temporal stability of water supply. Current estimations of reservoir evaporative loss are dependent on water area derived from a reservoir storage-area curve. Such curves are unavailable if the reservoir is located in a data-sparse region or questionable if long-term sedimentation has changed the original elevation-area relationship. We propose a remote sensing framework to estimate reservoir evaporative loss at the regional scale. This framework uses a multispectral water index to extract reservoir area from Landsat imagery and estimate monthly evaporation volume based on pan-derived evaporative rates. The optimal index threshold is determined based on local observations and extended to unobserved locations and periods. Built on the cloud computing capacity of the Google Earth Engine, this framework can efficiently analyze satellite images at large spatiotemporal scales, where such analysis is infeasible with a single computer. Our study involves 200 major reservoirs in Texas, captured in 17,811 Landsat images over a 32-year period. The results show that these reservoirs contribute to an annual evaporative loss of 8.0 billion cubic meters, equivalent to 20% of their total active storage or 53% of total annual water use in Texas. At five coastal basins, reservoir evaporative losses exceed the minimum freshwater inflows required to sustain ecosystem health and fishery productivity of the receiving estuaries. Reservoir evaporative loss can be significant enough to counterbalance the positive effects of impounding water and to offset the contribution of water conservation and reuse practices. Our results also reveal the spatially variable performance of the multispectral water index and indicate the limitation of using scene-level cloud cover to screen satellite images. This study demonstrates the advantage of combining satellite remote sensing and

    1985-04-01

    The purpose of this document is to describe the Crystalline Repository Project's (CRP) process for region-to-area screening of exposed and near-surface crystalline rock bodies in the three regions of the conterminous United States where crystalline rock is being evaluated as a potential host for the second nuclear waste repository (i.e., in the North Central, Northeastern, and Southeastern Regions). This document indicates how the US Department of Energy's (DOE) General Guidelines for the Recommendation of Sites for Nuclear Waste Repositories (10 CFR 960) were used to select and apply factors and variables for the region-to-area screening, explains how these factors and variable are to be applied in the region-to-area screening, and indicates how this methodology relates to the decision process leading to the selection of candidate areas. A brief general discussion of the screening process from the national survey through area screening and site recommendation is presented. This discussion sets the scene for detailed discussions which follow concerning the region-to-area screening process, the guidance provided by the DOE Siting Guidelines for establishing disqualifying factors and variables for screening, and application of the disqualifying factors and variables in the screening process. This document is complementary to the regional geologic and environmental characterization reports to be issued in the summer of 1985 as final documents. These reports will contain the geologic and environmental data base that will be used in conjunction with the methodology to conduct region-to-area screening

    Many studies have indicated the magnified increase of rainfall intensification, landsliding and subsequent sediment discharge due to the global warming effect. However, a few works synthesized the "chain reaction" from rainfall, landsliding to sediment discharge at the same time because of the limited observations of landslide area and sediment discharge during episodes. Besides, the sediment transport strongly depends on the sediment supply and stream power which interact conditionally. In this study, our goal is to build a model that can simulate time-series landslide area and subsequent sediment discharge. The synthesized model would be applied onto Tsengwen Reservoir watershed in southern Taiwan, where lots of landslides occur every year. Unlike other studies, our landslide model considers not only rainfall effect but also previous landslide status, which may be applied to landslide-dominated regions and explains the irrelevant relationship between typhoon rainfall and landslide area. Furthermore, our sediment transport model considers the sediment budget which couples transport- and supply-limited of sediment. The result shows that the simulated time-series landslide area and the sediment transport agree with the observation and the R2 are 0.88 and 0.56, respectively. Reactivated ratio of previous landslide area is 72.7% which indicates the high reoccurrence of historical landslide in landslide-dominated regions. We divided nine historical typhoons into three periods to demonstrate the effect of sediment supply/supply-limited condition upon sediment transport. For instance, the rainfall is smaller in period 3 than in period 1 but the sediment transport is higher in period 3 due to the catastrophic landslide (typhoon Morakot) during period 2. We argue that quantifying sediment transport should couple not only with water discharge but sediment budget, which is rarely considered in calculating sediment transport. Moreover, the parameterization of the controlling

    The concept of regional fuel cycle centers (RFCC) has attracted wide interest. The concept was endorsed by many countries in discussions at the General Conference of the International Atomic Energy Agency and at the General Assembly of the United Nations. Accordingly, in 1975, the IAEA initiated a detailed study of the RFCC concept. The Agency study has concentrated on what is referred to as the ''back-end'' of the fuel cycle because that is the portion which is currently problematic. The study covers transport, storage, processing and recycle activities starting from the time the spent fuel leaves the reactor storage pools and through all steps until the recycled fuel is in finished fuel elements and shipped to the reactor. A detailed evaluation of the specific features of large regional fuel cycle centers established on a multinational basis vis-a-vis smaller dispersed fuel cycle facilities set up on a national basis has been carried out. The methodology for assessment of alternative strategies for fuel storage, reprocessing, and recycling of plutonium has been developed, characteristic data on material flows and cost factors have been generated, and an analytic system has been developed to carry out such evaluations including appropriate sensitivity analysis. Studies in related areas on institutional and legal, organizational, environmental, materials control and other essential aspects have also been made. The material developed during the course of this Study would enable any group of interested Member States to examine and work out alternative strategies pertinent to their present and projected nuclear fuel cycle needs, as well as evolve institutional, legal and other appropriate frameworks or agreements for the establishment of fuel cycle centers on a multinational cooperative basis

    Regional heterogeneity in cortical cyto- and myeloarchitecture forms the structural basis of mapping of cortical areas in the human brain. In this study, we investigate the potential of diffusion MRI to probe the microstructure of cortical gray matter and its region-specific heterogeneity across cortical areas in the fixed human brain. High angular resolution diffusion imaging (HARDI) data at an isotropic resolution of 92-μm and 30 diffusion-encoding directions were acquired using a 3D diffusion-weighted gradient-and-spin-echo sequence, from prefrontal (Brodmann area 9), primary motor (area 4), primary somatosensory (area 3b), and primary visual (area 17) cortical specimens (n=3 each) from three human subjects. Further, the diffusion MR findings in these cortical areas were compared with histological silver impregnation of the same specimens, in order to investigate the underlying architectonic features that constitute the microstructural basis of diffusion-driven contrasts in cortical gray matter. Our data reveal distinct and region-specific diffusion MR contrasts across the studied areas, allowing delineation of intracortical bands of tangential fibers in specific layers-layer I, layer VI, and the inner and outer bands of Baillarger. The findings of this work demonstrate unique sensitivity of diffusion MRI to differentiate region-specific cortical microstructure in the human brain, and will be useful for myeloarchitectonic mapping of cortical areas as well as to achieve an understanding of the basis of diffusion NMR contrasts in cortical gray matter.

    Every summer, North Korea (NK) suffers from floods, resulting in decreased agricultural production and huge economic loss. Besides meteorological reasons, several factors can accelerate flood damage. Environmental studies about NK are difficult because NK is inaccessible due to the division of Korea. Remote sensing (RS) can be used to delineate flood inundated areas in inaccessible regions such as NK. The objective of this study was to investigate the spatial characteristics of flood susceptible areas (FSAs) using multi-temporal RS data and digital elevation model data. Such study will provide basic information to restore FSAs after reunification. Defining FSAs at the study site revealed that rice paddies with low elevation and low slope were the most susceptible areas to flood in NK. Numerous sediments from upper streams, especially streams through crop field areas on steeply sloped hills, might have been transported and deposited into stream channels, thus disturbing water flow. In conclusion, NK floods may have occurred not only due to meteorological factors but also due to inappropriate land use for flood management. In order to mitigate NK flood damage, reforestation is needed for terraced crop fields. In addition, drainage capacity for middle stream channel near rice paddies should be improved.

  4. A regional analysis of groundwater flow and salinity distribution in the Aespoe area

    1997-05-01

    A regional groundwater model of the Aespoe area has been formulated and applied. The model is three-dimensional, based on a grid of 100x100x36 cells and covers an area of 10x10 km 2 and a depth of 3 km. Equations are solved for the Darcy velocities and the salinity distribution, gravitational effects are thus fully accounted for. The model is used to simulate the general hydrology of the area as well as the influence of the Aespoe Hard Rock Laboratory (HRL). A specific task of the study is to evaluate relevant boundary conditions for the site-model and to show how these are influenced by Aespoe HRL. Studies of the stochastic conductivity field and the effect of density stratification are also reported. The general conclusion of the study is that the model provides a realistic and consistent picture of the area studied. Main arguments for this statement are: The formulation of the model is based on relevant conservation laws and embodies all physical processes believed to be important for the problem considered. The importance of gravitational forces is emphasised. A high resolution grid, which resolves topographical features and at the same time can simulate the effect of the HRL is used. Transmissivities and conductivities used in the model are based on field data. The model has been calibrated, using measured groundwater levels and salinity distributions with good results. A range of sensitivity studies has been carried out. These demonstrate that the model responds to variations in input data, for example the conductivity field in a realistic way. The model can thus be used to generate boundary conditions for a site scale model. The basic objective, to account for the regional influence in a site model, can hence be achieved. 7 refs, 32 figs

The major conclusions regarding the tectonic structure are: Three regional fault systems are identified, two steep NW and N trending and a third NNE trending with gentle ESE dips, the steep fault systems have strike slip generated deformation patterns both in the Precambrian structures and in the surface morphology, the post-glacial faults of the area are part of this fault pattern and represent movements mainly on reactivated, gently dipping zones, several suspected late or post-glacial, fault related features are found along the steep NW and N faults. Sites for drilling and geodetic networks for deformation measurements are suggested. Detailed background data are documented in additional 4 reports. The basic geophysical and geological datasets are documented in color plotted 1:250 000 maps. A tectonic interpretation map in the same scale has been produced by combined interpretation of magnetic, elevation, elevation relief and gravity data. (orig./HP) With 6 maps

    The author has studied maxillo-facial anatomical landmarks using Status X with two methods. The one has performed by application of contrast media on the human dry skull, the other has performed on living human skull as control group. Comparing the panagraphs taken by two methods, the author has drawn following results: 1. The panagraphs revealed the undistorted highly sharp panoramic shadows of each jaw on a film. 2. Diminishing the inserted anode tube to 4 cm (focal incisor distance 3 cm), overlapping-free representation of the in terdental spaces of the premolars and anterior teeth was taken. 3. Alternating the head position of the objects, direction of anode tube and film placing, the shadows of temporomandibular joint and zygomatic arch were taken without overlapping the other bone tissues. 4. In the panagraphs applied various shaped contrast media to each anatomical landmark, a radio-anatomical atlas which is necessary to interpret various bone tissues was taken. 5. In order to interpret panagraphic shadows easily, the author has tried this study by comparing the films of the living human skull with the films of the human dry skull applied contrast media.

    Full Text Available The climatic scenarios show a strong signal of warming in the Alpine area already for the mid-XXI century. The climate simulations, however, even when obtained with regional climate models (RCMs, are affected by strong errors when compared with observations, due both to their difficulties in representing the complex orography of the Alps and to limitations in their physical parametrization. Therefore, the aim of this work is to reduce these model biases by using a specific post processing statistic technique, in order to obtain a more suitable projection of climate change scenarios in the Alpine area. For our purposes we used a selection of regional climate models (RCMs runs which were developed in the framework of the ENSEMBLES project. They were carefully chosen with the aim to maximise the variety of leading global climate models and of the RCMs themselves, calculated on the SRES scenario A1B.

  11. An AHP-derived method for mapping the physical vulnerability of coastal areas at regional scales

    Full Text Available Assessing coastal vulnerability to climate change at regional scales is now mandatory in France since the adoption of recent laws to support adaptation to climate change. However, there is presently no commonly recognised method to assess accurately how sea level rise will modify coastal processes in the coming decades. Therefore, many assessments of the physical component of coastal vulnerability are presently based on a combined use of data (e.g. digital elevation models, historical shoreline and coastal geomorphology datasets, simple models and expert opinion. In this study, we assess the applicability and usefulness of a multi-criteria decision-mapping method (the analytical hierarchy process, AHP to map physical coastal vulnerability to erosion and flooding in a structured way. We apply the method in two regions of France: the coastal zones of Languedoc-Roussillon (north-western Mediterranean, France and the island of La Réunion (south-western Indian Ocean, notably using the regional geological maps. As expected, the results show not only the greater vulnerability of sand spits, estuaries and low-lying areas near to coastal lagoons in both regions, but also that of a thin strip of erodible cliffs exposed to waves in La Réunion. Despite gaps in knowledge and data, the method is found to provide a flexible and transportable framework to represent and aggregate existing knowledge and to support long-term coastal zone planning through the integration of such studies into existing adaptation schemes.

    This paper presents the concentrations of naturally occurring radionuclides 226 Ra, 232 Th and 40 K measured in groundwater samples collected from Aden governorate South of Yemen region using gamma spectroscopy. A total of 37 groundwater samples were collected from four areas in Aden governorate. The average activity concentrations for groundwater from Beer Ahmed area were 1.60 Bq/L, 1.25 Bq/L and 16.90 Bq/L for 226 Ra, 232 Th and 40 K respectively and from Beer Fadle area were 1.45 Bq/L, 0.87 Bq/L and 19.8 Bq/L for 226 Ra, 232 Th and 40 K, respectively, while that for groundwater samples from Daar-saad area were 1.27 Bq/L, 1.18 Bq/L and 18.28 Bq/L for 226 Ra, 232 Th and 40 K, respectively and Al-Masabian area were 1.55 Bq/L, 1.421 Bq/L and 19.03 Bq/L for 226 Ra, 232 Th and 40 K respectively. Furthermore, annual effective dose equivalent of ingestion of these waters was calculated. The results showed that the annual dose obtained in the present study was much higher than the recommended value (0.1 mSv/year) as reported by WHO. The results were compared with those for drinking water. (author)

    The paper worked out a model of the wide area supply network which combines the element technology being developed in the eco/energy urban project and the existing technology to apply it to the actually existing city, and the evaluation study was made of energy conservation effects, environmental preservation effects, economical efficiency, etc. The FY 2000 results were reported. In this fiscal year, a case was studied of using the exhaust heat from waste incineration plant by wide area network in the region having a plan of redevelopment/rezoning of the city of Osaka where heat is in great demand. The results of the study were as follows: The total primary energy consumption amount is reduced by 16.3-19.7% in the conventional heat insulation pipe method and by 19.2-20.6% in the vacuum heat insulation method. As to the environmental preservation, the CO2 reduction amount is 36.9-40.0%, and the NOx reduction amount is 43.7-45.5%, which indicated much more improvement than in the present situation. In the aspect of economical efficiency, the result indicated that in the case of the shortest piping, much economical efficiency is expected even without subsidies if considered of the carbon tax.

    Full Text Available Land degradation has expanded in the Mediterranean region as a result of a variety of factors, including economic and population growth, land-use changes and climate variations. The level of land vulnerability to degradation and its growth over time are distributed heterogeneously over space, concentrating on landscapes exposed to high human pressure. The present study investigates the level of land vulnerability to degradation in a shrinking urban area (Rome, Italy at four points in time (1960, 1990, 2000 and 2010 and it identifies relevant factors negatively impacting the quality of land and the level of landscape fragmentation. A multi-domain assessment of land vulnerability incorporating indicators of climate quality, soil quality, vegetation quality and land management quality was carried out based on the Environmentally Sensitive Area (ESA framework. The highest rate of growth in the level of land vulnerability was observed in low-density suburban areas. The peri-urban mosaic formed by coastal woodlands and traditional cropland preserved high-quality land with a stable degree of vulnerability over time. Evidence suggests that the agro-forest mosaic surrounding Mediterranean cities act as a “buffer zone” mitigating on-site and off-site land degradation. The conservation of relict natural landscapes is a crucial target for multi-scale policies combating land degradation in suburban dry regions.

    Introduction: After the 1995 Kobe earthquake, the Japanese government increased its focus and funding of earthquake hazards evaluation, studies of man-made structures integrity, and emergency response planning in the major urban centers. A new agency, the Ministry of Education, Science, Sports and Culture (MEXT) has started a five-year program titled as Special Project for Earthquake Disaster Mitigation in Urban Areas (abbreviated to Dai-dai-toku in Japanese) since 2002. The project includes four programs: I. Regional characterization of the crust in metropolitan areas for prediction of strong ground motion. II. Significant improvement of seismic performance of structure. III. Advanced disaster management system. IV. Investigation of earthquake disaster mitigation research results. We will present the results from the first program conducted in 2002 and 2003. Regional Characterization of the Crust in Metropolitan Areas for Prediction of Strong Ground Motion: A long-term goal is to produce map of reliable estimations of strong ground motion. This requires accurate determination of ground motion response, which includes a source process, an effect of propagation path, and near surface response. The new five-year project was aimed to characterize the "source" and "propagation path" in the Kanto (Tokyo) region and Kinki (Osaka) region. The 1923 Kanto Earthquake is one of the important targets to be addressed in the project. The proximity of the Pacific and Philippine Sea subducting plates requires study of the relationship between earthquakes and regional tectonics. This project focuses on identification and geometry of: 1) Source faults, 2) Subducting plates and mega-thrust faults, 3) Crustal structure, 4) Seismogenic zone, 5) Sedimentary basins, 6) 3D velocity properties We have conducted a series of seismic reflection and refraction experiment in the Kanto region. In 2002 we have completed to deploy seismic profiling lines in the Boso peninsula (112 km) and the

    A geologic and geochemical investigation and a survey of mines and prospects were conducted to evaluate the mineral-resource potential of the Spanish Peaks Wilderness Study Area, Huerfano and Las Animas Counties, in south-central Colorado. Anomalous gold, silver, copper, lead, and zinc concentrations in rocks and in stream sediments from drainage basins in the vicinity of the old mines and prospects on West Spanish Peak indicate a substantiated mineral-resource potential for base and precious metals in the area surrounding this peak; however, the mineralized veins are sparse, small in size, and generally low in grade. There is a possibility that coal may underlie the study area, but it would be at great depth and it is unlikely that it would have survived the intense igneous activity in the area. There is little likelihood for the occurrence of oil and gas because of the lack of structural traps and the igneous activity.

    This study is objected to characterize groundwater resources, to assess groundwater contamination, and to produce hydrogeological and related thematic maps of the study area. The study area, Younggwang County, Chonnam Province, covers the area of 460 km{sup 2}. To accomplish the objectives various studies have been carried out including general and structural geology, GIS, hydrogeology, geophysics and hydrogeochemical analysis. Geophysical explorations, dipole-dipole resistivity, Schulumberger sounding and magnetic method, were executed for investigating geologic structure and determining test borehole sites. Some test boreholes such as, Honggok, Donggan, Weolsan and Seolmae hit aquifer structures. Geophysical logging, such as gamma ray, temperature, water conductivity, electrical resistivity, self-potential were also executed for petrological differentiation and in out flow of groundwater. The recharge rate of granitic region is more than the others, which derived by the analysis of 7 low-flow measurements in 10 small watersheds in the area. The recharge rate has been estimated at 7.2%(99.3 mm/year) in the vicinity. Well inventory of the area included 197 deep wells and 43 shallow wells. In addition, 10 stream samples and one spring were surveyed for water level, water temperature, pH, EC, TDS and the concentration of dissolved oxygen(DO). Regional groundwater pollution susceptibility was analyzed using GIS technique. A standard method, `DRASTIC` developed by US EPA, was applied to evaluate groundwater pollution potential and aquifer susceptibility. Resulting DRASTIC indices ranged from 52 to 141, and the Pesticide indices from 61 to 187. Seawater intrusion phenomena in Sangsari-Hasari are considered and evaluated by well inventory and the selected borehole`s electric conductivity(EC) logging. Seawater intrusion to the vulnerable coastal alluvium aquifers is generally depleted with time. The amount of potential groundwater resources in the study area is estimated

    Planning and permitting considerations for wind energy project siting in mountainous areas were discussed. Mountainous regions have a specific set of environmental and socio-economic concerns. Potential disruptions to wildlife, noise, and visual impacts are a primary concern in the assessment of potential wind farm projects. Alpine habitats are unique and often contain fragile and endangered species. Reclamation techniques for mountainous habitats have not been extensively tested, and the sites are not as resilient as sites located in other ecosystems. In addition, alpine habitats are often migratory corridors and breeding grounds for threatened or endangered birds. In the winter months, alpine habitats are used by caribou, grizzly bears, and wolverine dens. Bats are also present at high elevations. It is often difficult to conduct baseline and monitoring studies in mountainous areas since alpine habitat is subject to rapid weather changes, and has a very short construction period. tabs., figs.

The research instrument was psychological capital scales with 28 items (α = 0.953 and work engagement scales with 29 items (α = 0.938. The results by simple regression analysis obtained rxy = 0.716, with p value = 0.000 (p <0.05. The results indicated that there was a positive correlation between psychological capital and work engagement. The higher psychological capital was higher work engagement. Coefficient of determination by 51,3, it meaning that psychological capital effectively contributed for 51,3 % of work engagement. The remaining 48,7 % determined by other factors that are not revealed in this study, for example: job resources and job demands. Keywords: Psychological capital, work engagement, employee

  1. Region-specificity of GABAA receptor mediated effects on orientation and direction selectivity in cat visual cortical area 18.

    2009-01-01

    The role of GABAergic inhibition in orientation and direction selectivity has been investigated with the GABA(A)-Blocker bicuculline in the cat visual cortex, and results indicated a region specific difference of functional contributions of GABAergic inhibition in areas 17 and 18. In area 17 inhibition appeared mainly involved in sculpturing orientation and direction tuning, while in area 18 inhibition seemed more closely associated with temporal receptive field properties. However, different types of stimuli were used to test areas 17 and 18 and further studies performed in area 17 suggested an important influence of the stimulus type (single light bars vs. moving gratings) on the evoked responses (transient vs. sustained) and inhibitory mechanisms (GABA(A) vs. GABA(B)) which in turn might be more decisive for the specific results than the cortical region. To insert the missing link in this chain of arguments it was necessary to study GABAergic inhibition in area 18 with moving light bars, which has not been done so far. Therefore, in the present study we investigated area 18 cells responding to oriented moving light bars with extracellular recordings and reversible microiontophoretic blockade of GABAergig inhibition with bicuculline methiodide. The majority of neurons was characterized by a pronounced orientation specificity and variable degrees of direction selectivity. GABA(A)ergic inhibition significantly influenced preferred orientation and preferred direction in area 18. During the action of bicuculline orientation tuning width increased and orientation and direction selectivity indices decreased. Our results obtained in area 18 with moving bar stimuli, although in the proportion of affected cells similar to those described in area 17, quantitatively matched the findings for direction and orientation specificity obtained with moving gratings in area 18. Accordingly, stimulus type is not decisive in area 18 and the GABA(A) dependent, inhibitory intracortical

    The WIPP water-balance study area defined here comprises approx.2000 mi 2 in Eddy and Lea Counties, southeastern New Mexico. Inflows to the study area are precipitation (roughly 1.47 x 10 6 ac-ft/y), surface water (roughly 1.1 x 10 5 ac-ft/y), water imported by municipalities and industries (roughly 3 x 10 4 ac-ft/y), and ground water (volume not estimated). Outflows from the area are evapotranspiration (roughly 1.5 x 10 6 ac-ft/y), surface water (roughly 1.2 x 10 5 ac-ft/y), and possibly some ground water. The volume of surface and ground water in storage in Nash Draw has increased since the beginning of potash refining. Regional ground-water flow in aquifers above the Salado Formation is from the northeast to the southwest, although this pattern is interrupted by Clayton Basin, Nash Draw, and San Simon Swale. The Pecos River is the only important perennial stream. Most of the area has no integrated surface-water drainage. The available data suggest that approx.1600 mi 2 of the study area are hydrologically separate from Nash Draw and the WIPP site. Ground water north of Highway 180 apparently discharges into Clayton Basin and evaporates. Water in San Simon Swale apparently percolates downward and flows to the southeast. Data are inadequate to create a water budget for the Nash Draw-WIPP site hydrologic system alone, although an attempt to do so can provide guidance for further study

  3. Critical review of the draft Area Recommendation Report and region-to-area screening methodology for the Crystalline Repository Project

    International Nuclear Information System (INIS)

    1986-01-01

    Two documents related to the Crystalline Repository Project have been reviewed. Comments and concerns related to the review of the ''Region-To-Area Screening Methodology'' and the ''Draft Area Recommendation Report'' are presented. These comments will be considered in preparation of the Final Area Recommendation Report, which will serve to formally identify potentially acceptable sites for a second repository in crystalline rock. Following a detailed review of the aforementioned documents, it is concluded that the identification of proposed potentially acceptable sites in the Draft Area Recommendation Report is based on questionable screening methodology and often incomplete data. As a result, ''favorable characteristics'' that are ascribed to each of the proposed potentially acceptable sites are, in many cases, misleading

    Highlights: • We assessed the bioenergy potential of conservation areas and roadsides in Flanders. • An area of 31,055 ha produces 203 kton DM of herbaceous biomass annually. • The associated biomass supply chain was optimized with OPTIMASS in four scenarios. • The net energy balance of the studied systems was 7 GJ ha −1 in the 2020 scenarios. • We show that this biomass can play a role to meet the increased biomass demand in 2020. - Abstract: In many urbanized areas the roadside and nature conservation management offers a biomass-for-bioenergy resource potential which is barely valorized, because of the fragmented biomass production sites and the scarcity of accurate data on the spatial availability of the biomass. In this study, a GIS based assessment was performed to determine the regional non-woody biomass-for-bioenergy potential for biogas from conservation areas and roadsides in Flanders, Belgium. These systems, with an area of 31,055 ha, have an annual herbaceous biomass production of 203 kton dry matter. The full associated biomass-to-bioenergy supply chain was optimized in four scenarios to maximize the net energy output and the profit. The scenario analysis was performed with OPTIMASS, a recently developed GIS based strategic decision support system. The analysis showed that the energetic valorization of conservation and roadside biomass through anaerobic digestion had a positive net energy balance, although there is still much room for improvements. Economically, however, it is a less interesting biomass resource. Most likely, the economic picture would change when other ecosystem services delivered by the protected biodiversity would be taken into account. Future technical advances and governmental incentives, like green energy certificates, will be necessary to incorporate the biomass into the energy chain. By tackling the existing barriers and providing a detailed methodology for biomass potential assessments, this study tries to

    Malaria is a worldwide public health problem; parasites from the genus Plasmodium are the aetiological agent for this disease. The parasites are mostly diagnosed by conventional microscopy-based techniques; however, their limitations have led to under-registering the reported prevalence of Plasmodium species. This study has thus been aimed at evaluating the infection and coinfection prevalence of 3 species of Plasmodium spp., in an area of the Colombian Amazon region. Blood samples were taken from 671 symptomatic patients by skin puncture; a nested PCR amplifying the 18S ssRNA region was used on all samples to determine the presence of P. vivax, P. malariae and P. falciparum. Statistical analysis determined infection and coinfection frequency; the association between infection and different factors was established. The results showed that P. vivax was the species having the greatest frequency in the study population (61.4%), followed by P. malariae (43.8%) and P. falciparum (11.8%). The study revealed that 35.8% of the population had coinfection, the P. vivax/P. malariae combination occurring most frequently (28.3%); factors such as age, geographical origin and clinical manifestations were found to be associated with triple-infection. The prevalence reported in this study differed from previous studies in Colombia; the results suggest that diagnosis using conventional techniques could be giving rise to underestimating some Plasmodium spp. species having high circulation rates in Colombia (particularly in the Colombian Amazon region). The present study's results revealed a high prevalence of P. malariae and mixed infections in the population being studied. The results provide relevant information which should facilitate updating the epidemiological panorama and species' distribution so as to include control, prevention and follow-up measures.

    Full Text Available In the first part, the author outlines the development of area studies in contemporary comparative politics, and points to their importance for the development of political science. In the second part, she examines the methodology – research design and methods – of regional comparatistics, paying particular attention to the problem of defining the region as a central category in this field of comparative politics. The third and central part is focused on the emergence of Eastern Europe as a historical-political and socio-cultural region in the course of history, especially after World War II, and on its dissolution in the processes of democratic transformation of communist regimes in the last two decades. The dissolution of Eastern Europe has resulted in restoration of a tripartite political geography in the area which it used to take up, made up of Central Europe, Southeast Europe and the proper Eastern Europe.

  12. Belledune area health study : summary report

    2005-02-01

    The Belledune area has been home to various industrial activities such as mining, smelting, fertilizer plants, battery-recycling plants, gypsum plants, sawmills, and a coal-fired electricity generating facility. These industries have had various types and quantities of emissions over the past 4 decades that may have impacted on the health of people in the area. This report provided details of the Belledune Health Area Study. The objective of the study was to ensure that the concerns of residents were addressed and that the historical and human health risks associated with past and current industrial activities were quantified. The current health status of residents in the area was examined with reference to environmental exposures, and recommendations for future studies and research based on the results of the study were presented. Two main components were used: the human health risk assessment (HHRA), and community health status assessment (CHSA). Best estimate calculations for residents in the core communities showed that exposures to cadmium, lead and mercury were predicted to be below toxicity reference values. In Belledune itself, child exposures to cadmium and mercury were above the toxicity reference value. Results indicated that the health status pattern for the study area was different from that found in the surrounding areas. There was a statistically significantly elevated incidence of oral, respiratory, and prostate cancer and elevated incidences of kidney and colorectal cancer. There was a higher mortality rate than expected, and there were more deaths than expected due to circulatory disease, cancer and other causes such as accidents and suicides. An expanded survey of blood lead among child residents and pregnant women was recommended. A program was launched to collect data on metal concentrations in fish from the Baie des Chaleurs and additional data on vegetables from the Greater Belledune area.

  17. Cesium-137 inventory of the undisturbed soil areas in the Londrina Region, Parana, Brazil

    International Nuclear Information System (INIS)

    Andrello, Avacir C.; Appoloni, Carlos Roberto

    2005-01-01

    Cesium-137 is an artificial radionuclide introduced in the environment through the radioactive fallout of the superficial tests of nuclear weapons. The cesium-137 deposition occurred to middles of the 1980-decade and, due to the Chernobyl accident, great part of Europe had a additional fallout of cesium-137. The contaminations of this accident do not have reached Southern Hemisphere. Cesium-137 is an alkaline metal, high electropositive, that in contact with the soil is strongly adsorbed to the clay in the FES (Frayed Edge Sites) and RES (Regular Edge Sites) positions, and it movement by chemical processes in the soil is insignificant. Because of this, cesium-137 became a good soil marker, and its movement is related to the soil movement particles, so that the cesium-137 have been used in the study of the soil redistribution processes, as a tool of quantifying the rates of soil losses and gain. To use this methodology, it is necessary the knowledge of the reference inventory of cesium-137, that is given as function of the total concentration of cesium-137 deposited in an area by the radioactive fallout. If a sampling point presents less cesium-137 than the reference inventory, this point is considered a point with soil loss; otherwise, the point is considered a point with soil deposition. To evaluate the cesium-137 inventory in the Londrina region, four areas of the undisturbed soil were sampling in grid of 3x3, with a distance of 9 meters among the points. Of these four sampling areas, three areas were of native forest (labeled Mata1, Mata2 and Mata UEL), and one was a pasture area. Cesium-137 inventory was 223 ± 41 Bq m -2 , 240 ± 65 Bq m -2 and 305 ± 36 Bq m -2 for Mata UEL, Mata1 and Mata2, respectively, and of 211 ± 28 Bq m -2 for the native pasture. Considering the deviation in each value, it is not possible to conclude that there are differences among the values of cesium-137 inventory, so that the average reference inventory of cesium-137 for the

    The maxilla is generally known as a site where anatomical limitations make it difficult to obtain sufficient bone volume. A large amount of bone exists in the canine region between the anterior margin of the maxillary sinus and the piriform aperture margin. Although this region is crucial for implant treatments, there have not been any reports on morphological studies of the region. In this study, we investigated the morphology of the canine region based on CT, and also the morphology and position of the maxillary sinus located posterior to the canine region. The results were as follows: In the area above the anterior nasal spine, the higher the level, the smaller the mesio-distal length and the bucco-lingual width tended to become. In the area above the anterior nasal spine, the mesio-distal length and the bucco-lingual width tended to be smaller in female patients than in male patients. In the area above the anterior nasal spine, no significant differences in mesio-distal length and bucco-lingual width were observed between dentulous and edentulous jaws. The morphology of the maxillary sinus was mainly of an inverse-trapezoidal, circular, or triangular form. The position of the anterior wall of the maxillary sinus was most frequently found at the site corresponding to the second premolar. Through this study, we have reconfirmed that the canine region is vital for implant treatments in the maxilla. (author)

    Studies on the behaviour and transport of 137 Cs in urban areas, including, resuspension and deposition experiments, 137 Cs uptake by leafy vegetables and small domestic animals that accidentally ingested contaminated soil, were performed in a house located at 57 t h Street near the main focus of contamination. The resuspension of surface soil did not contribute much to the spreading of the radionuclide in Goiania, but can lead to the local contamination of vegetables, equipment, structures and other environmental surfaces. The mechanism also presented a seasonal effect. The soil is an important medium for the uptake of 137 Cs by small domestic animals. The street dust sampling is a suitable method to assess the dispersion of 137 Cs in urban areas. After 10 years, the radionuclide activity concentration is restricted only to the initially impacted area an it is decreasing with time. (author)

    Ultra-high-field (UHF) MRI is ideally suited for structural and functional imaging of the brain. High-resolution structural MRI can be used to map the anatomical boundaries between functional domains of the brain by identifying changes related to the pattern of myelination within cortical gray matter, opening up the possibility to study the relationship between functional domains and underlying structure in vivo. In a recent study, we demonstrated the correspondence between functional (based on retinotopic mapping) and structural (based on changes in T2(⁎)-weighted images linked to myelination) parcellations of the primary visual cortex (V1) in vivo at 7T (Sanchez-Panchuelo et al., 2012b). Here, we take advantage of the improved BOLD CNR and high spatial resolution achievable at 7T to study regional structural variations across the functionally defined areas within the primary somatosensory cortex (S1) in individual subjects. Using a traveling wave fMRI paradigm to map the internal somatotopic representation of the index, middle, and ring fingers in S1, we were able to identify multiple map reversals at the tip and base, corresponding to the boundaries between Brodmann areas 3a, 3b, 1 and 2. Based on high resolution structural MRI data acquired in the same subjects, we inspected these functionally-parcellated Brodmann areas for differences in cortical thickness and MR contrast measures (magnetization transfer ratio (MTR) and signal intensity in phase sensitive inversion recovery (PSIR) images) that are sensitive to myelination. Consistent area-related differences in cortical thickness and MTR/PSIR measurements were found across subjects. However these measures did not have sufficient sensitivity to allow definition of areal boundaries. Copyright © 2013 Elsevier Inc. All rights reserved.

    The Olduvai Gorge and Laetoli basins, located within the Ngorogoro Conservation Area (NCA), are a cornerstone for understanding the evolution of early humans and are two paleo-antropological excavation sites of global importance. NCA is located at the boundary between the Tanzanian Craton and East African Rift (EAR), in the vicinity of Ngorongoro Crater and other major volcanic edifices. Thus, understanding the geology and tectonics of the NCA may shed light onto the question why early Hominins settled in this region. Environmental and geological conditions in the Olduvai and Laetoli region that promoted human settlement and development are still debated by geologists and paleo-anthropologists. Paleo-geographical reconstructions of the study area of the last 2 million years may take advantage of modern passive seismology. Therefore, we installed a dense seismic network covering a surface of approximately 30 x 40 km within the NCA to map the depth extent of known faults, and to identify seismically active faults that have no surface expression. Our ten seismic stations, equipped with Trillium Compact 120 s sensors, started to operate in June 2016 and will continue for a total of 2 years. At the end of the first year, other 5 stations will densify our network. Here we analyse data quality of the first four months of continuous recordings. Our network provides good quality 3-C waveforms in the frequency range of 0.7-50 Hz. Vertical component seismograms record frequencies reliably down to 8 mHz. Preliminary results of the seismicity obtained with standard location procedures show that NCA is characterised by frequent tectonic seismicity (not volcano-related) with Ml between 0.5 and 2.0. Seismic activity is more frequent in the South (Laetoli region) where major fault systems have not been recognised at the surface yet.

    During the last decades, expansion of settlements into areas prone to landslides in Iraq has increased the importance of accurate hazard assessment. Susceptibility mapping provides information about hazardous locations and thus helps to potentially prevent infrastructure damage due to mass wasting. The aim of this study is to evaluate and compare frequency ratio (FR), weight of evidence (WOE), logistic regression (LR) and probit regression (PR) approaches in combination with new geomorphological indices to determine the landslide susceptibility index (LSI). We tested these four methods in Mawat area, Kurdistan Region, NE Iraq, where landslides occur frequently. For this purpose, we evaluated 16 geomorphological, geological and environmental predicting factors mainly derived from the advanced spaceborne thermal emission and reflection radiometer (ASTER) satellite. The available reference inventory includes 351 landslides representing a cumulative surface of 3.127 km2. This reference inventory was mapped from QuickBird data by manual delineation and partly verified by field survey. The areas under curve (AUC) of the receiver operating characteristic (ROC), and relative landslide density (R index) show that all models perform similarly and that focus should be put on the careful selection of proxies. The results indicate that the lithology and the slope aspects play major roles for landslide occurrences. Furthermore, this paper demonstrates that using hypsometric integral as a prediction factor instead of slope curvature gives better results and increases the accuracy of the LSI.

    This report presents the results of an aggregate area management study (AAMS) for the Semi-Works Aggregate Area in the 200 Areas of the US Department of Energy (DOE) . Hanford Site in Washington State. This scoping level study provides the basis for initiating Remedial Investigation/Feasibility Study (RI/FS) activities under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) or Resource Conservation and Recovery Act (RCRA) Facility Investigations WD and Corrective Measures Studies (CMS) under RCRA. This report also integrates select RCRA treatment storage, or disposal (TSD) closure activities with CERCLA and RCRA past-practice investigations. This approach is described and justified in The Hanford Federal Facility Agreement and Consent Order Change Package. This strategy provides new concepts for: accelerating decision-malting by maximizing the use of existing data consistent with data quality objectives (DQOs); and undertaking expedited response actions (ERAS) and/or interim remedial measures (IRMs), as appropriate, to either remove threats to human health and welfare and the environment, or to reduce risk by reducing toxicity, mobility, or volume of contaminants

    It has been well documented that the thyroid gland is one of the most radiosensitive of organs, especially when exposure occurs during childhood. It is known as well that childhood exposure to radioactive iodine increases thyroid cancer risk. Conducting thyroid screening in regions adjacent to the Semipalatinsk Test Site (STS) area is very important for medical examination, data management and thyroid dose reconstruction. Our experience of thyroid screening based on our screening projects in Kurchatov and several regions adjacent to STS (more than 4,000 screened patients) allowed to work out the most appropriate screening protocol. A retrospective analysis of the results of surgical treatment of the 7,271 patients with thyroid abnormalities in the Semipalatinsk, Pavlodar and Ust-Kamenogorsk regions of Kazakstan and study the histological staging of 7,271 surgically removed thyroid glands was preceded by our thyroid screening projects. Ours is the first study in the Semipalatinsk region that covers the period 1966-1998.Taking into account the onset of population effective doses during 1962, it was decided to distinguish 6 periods of observation. It is known that basic effective equivalent doses for the majority of the region's population were established by radioactive events in the period 1949-1962. This explains our focus on the year 1962, but thyroid dose reconstruction matter as well as other radiation related problems are still in the progress. We need to get the accurate dosimetry data. Selection of study subjects based on the appropriate criteria needed to be adjusted and clarified in accordance with the main goal of the project and radiation related information. All specialists involved in the thyroid screening project, data management, data analyses and interpretation of the results must be trained and must be highly qualified specialists in this field of science and practice.

    Alveoli in the hilar region comprise the peripheral area containing daughter branches from subsegmental or one more divisional peripheral bronchi. Pulmonary perfusion in hilar region was examined by SPECT (single photon emission CT) in ten normal volunteers. ROI (region of interest) in the axial images were set in the hilar region, the upper, middle and lower lung fields with 10.8 mm thickness. Counts/one pixel (C/P) were calculated in these ROI. There was a tendency of C/P increase from upper to lower lung field. And there were no significant differences in C/P increase between hilar region and other axial fields. In the chronic obstructive pulmonary diseases, however, ventilation studies in the previous reports using Xe dynamic CT or PET (positron emission tomography) showed differences between outer region and hilar region. This method will be expected to evaluate the pulmonary perfusion not only in the whole lung but in different lung areas, including the hilar region in the chronic obstructive pulmonary diseases.

    The areas of focus of the Santa Barbara and Riverside groups in conducting water demand studies are the central and southern California regional test sites, respectively. Within each test site, sub-areas have been selected for use in the making of detailed investigations. Within each of these sub-areas an in-depth evaluation is being made as to the capability of remote sensing systems to provide pertinent data relative to water demand phenomena. These more limited sub-areas are: (1) Kern County and the San Joaquin Basin; (2) Chino-Riverside Basin; and (3) the Imperial Valley. Rational for the selection of these subareas included the following: Much of the previous remote sensing research had been conducted in these areas and therefore a great deal of remote sensing imagery and pertinent ground truth for the areas was already available.

    Full Text Available Results deriving from a research focused on the interplay between landslides and urban development are presented here, with reference to two densely populated settings located in the Campania region, Italy: the city of Naples and the island of Ischia. Both areas suffer adverse consequences from various types of landslides since at least 2000 yr. Our study evidences that, despite the long history of slope instabilities, the urban evolution, often illegal, disregarded the high landslide propensity of the hillsides; thus, unsafe lands have been occupied, even in recent years, when proper and strict rules have been enacted to downgrade the landslide risk. It is finally argued that future guidelines should not be entirely based upon physical countermeasures against mass movements. On the contrary, national and local authorities should enforce the territorial control, obliging citizens to respect the existing regulations and emphasizing the role of alternative, non-structural solutions.

    Yin, Jingjing; Tian, Lili

    2014-03-15

    In the field of diagnostic studies, the area under the ROC curve (AUC) serves as an overall measure of a biomarker/diagnostic test's accuracy. Youden index, defined as the overall correct classification rate minus one at the optimal cut-off point, is another popular index. For continuous biomarkers of binary disease status, although researchers mainly evaluate the diagnostic accuracy using AUC, for the purpose of making diagnosis, Youden index provides an important and direct measure of the diagnostic accuracy at the optimal threshold and hence should be taken into consideration in addition to AUC. Furthermore, AUC and Youden index are generally correlated. In this paper, we initiate the idea of evaluating diagnostic accuracy based on AUC and Youden index simultaneously. As the first step toward this direction, this paper only focuses on the confidence region estimation of AUC and Youden index for a single marker. We present both parametric and non-parametric approaches for estimating joint confidence region of AUC and Youden index. We carry out extensive simulation study to evaluate the performance of the proposed methods. In the end, we apply the proposed methods to a real data set. Copyright © 2013 John Wiley & Sons, Ltd.

    The Mediterranean region is highly susceptible to wildfires. On average, about 60,000 fires take place in this region every year, burning on average half a million hectares of forests and natural vegetation. Wildfires cause environmental degradation and affect the lives of thousands of people in the region. In order to minimize the consequences of these catastrophic events, fire managers and national authorities need to have in their disposal accurate and updated spatial information concerning the size of the burned area as well as the burn severity patterns. Mapping burned areas and burn severity patterns is necessary to effectively support the decision-making process in what concerns strategic (long-term) planning with the definition of post-fire actions at European and national scales. Although a comprehensive archive of burnt areas exists at the European Forest Fire Information System, the analysis of the severity of the areas affected by forest fires in the region is not yet available. Fire severity is influenced by many variables, including fuel type, topography and meteorological conditions before and during the fire. The analysis of fire severity is essential to determine the socio-economic impact of forest fires, to assess fire impacts, and to determine the need of post-fire rehabilitation measures. Moreover, fire severity is linked to forest fire emissions and determines the rate of recovery of the vegetation after the fire. Satellite imagery can give important insights about the conditions of the live fuel moisture content and can be used to assess changes on vegetation structure and vitality after forest fires. Fire events occurred in Greece, Portugal and Spain during the fire season of 2009 were recorded and analyzed in a GIS environment. The Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI) and the Normalized Burn Ratio (NBR) were calculated from 8-days composites MODIS/TERRA imagery from March to October 2009.

    The main objective of this study is to support the development of a preliminary Site Description of the Laxemar subarea on a regional-scale based on the available data of November 2004 (Data Freeze L1.2). A more specific objective of this study is to assess the role of both known and less quantified hydrogeological conditions in determining the present-day distribution of saline groundwater in the Laxemar subarea on a regional-scale. An improved understanding of the palaeo-hydrogeology is necessary in order to gain credibility for the Site Description in general and the hydrogeological description in particular. This is to serve as a basis for describing the present hydrogeological conditions on a local-scale, as well as predictions of future hydrogeological conditions. Another objective is to assess the flow-paths from the local-scale model domain, based on the present-day flow conditions, to assess the distribution of discharge and recharge areas connected to the flow at the approximate repository depth to inform the Preliminary Safety Evaluation. Significant new features incorporated in the modelling include: a depth variation in hydraulic properties within the deformation zones; a dependence on rock domain and depth in the rock mass properties in regional-scale models; a more detailed model of the overburden in terms of a layered system of spatially variable thickness made up of several different types of Quaternary deposits has been implemented; and several variants on the position of the watertable have been tried. The motivation for introducing a dependence on rock domain was guided by the hydrogeological interpretation with the aim of honouring the observed differences in hydraulic properties measured at the boreholes.

    Full Text Available The role of Regions appears reconfigured by the "reshaping" of national States. Besides, under a sub-regional scale, forms of governance have been launched, redefining a new territoriality. In Italy, the role of the Regions and Cities is more and more important in the decision-making processes of the territories and it is also characterized by the recent establishment of the metropolitan cities, but still not geo-politically defined. There is, in fact, a constitutional reform process through the region's reorganization legislative autonomy and strengthening of local governments. In this context, some areas are characterized by social unrest that includes new forms of poverty, urban malaise and marginalization, due also to the financial and economic crisis whose signs of recovery are still very weak. In the European Union, the programming decisions considered the policy of development and cohesion also at the local scale. The 2014-2020 EU programming cycle, in fact, has defined the main role of metropolitan cities, but also of cities and internal areas. The contribution will analyze Puglia, region of southern Italy, and the metropolitan area of Bari, the regional capital, in order to verify policies concerning the social field, both through "strategic planning" and launching the so-called "smart city" experience. In the metropolitan city, indeed, there is already an orientation towards the "social innovation" to address the issues of social cohesion and inclusion, consistent to sustainable development.

    Full text: The study of radiation situation (on the position of May 1989) in Beskaragai area of Semipalatinsk region showed that the level of γ-radiation on it's territory reached 13-20 μR/hour, which was determined by the traces of long living radionuclides. In the inhabited regions of Dolon, Kanonerka, Buras, Ramadan villages the effect of deepening was noticed, α-particle's density level has reached maximum on the depth of approximately 10 cm, and further it decreases up to the 30 cm depth, This circumstance witnesses about the fact that we are talking about radioactive traces of many years ago happening with a time going to the depth from the upper coverage of soil. We've made the evaluation of radiation influence's genetic effects on the man's population. Cytogenetic analysis (with the use of G-method of chromosome's coloring) at whole in Beskaragai region shows that the frequency of aberrations for the cell among the inhabitants of the region is obviously higher 3.3 times at average in the region than among the population of the controlled area. During the study of the cytogenetic effects of increased radiation level's influence it is important first of all to determine the frequency of chromosome type aberrations - dicentric chromosomes, centric circles, acentric pair fragments. As it is known, the level of chromosome type aberrations is sufficiently well correlated with the doze, We have determined accumulative doze of radiation using the formula (D.C. Lloyd at all. 1992) for the calculation of dicentrics under the chronical influence of the small dozes of ionized radiation. According to the made calculations the oriented reconstruction of radiation dozes in Beskaragai region made 11 ber = 0.11 Sv, for the Dolon village - 14 ber, Kanonerka village - 13 ber, Buras village - 6 ber, Ramadan - 9.5 ber. Presented data allows to ask the question about the more spread use of cytogenetic method of research among the different population's categories living at

    Full Text Available Transfrontier Conservation Areas (TFCAs initiatives in the Southern African Development Community (SADC region offer hope for providing a mechanism for resolving political tensions and conflicts which are not only related to environmental issues but to security concerns as well. The geopolitical implications of TFCAs in the SADC region cannot be overemphasised with regard to international relations and regional integration. The SADS region is characterised by histories of contested military balance of power and geopolitical rivalries which have a potential to degenerate into military confrontation. Although there is a strong belief in multilateral co-operation among SADC member countries, most of them often engage the international community at the bilateral level. Moreover, there is disharmony in constitutional applications of the rule of law, respect of human rights and good governance. However, TFCAs initiatives in Southern Africa have been seen as offering an opportunity to heal the wounds of pre- and post-independence wars of destabilisation through the encouragement of inter-state collaboration and co-operation by giving governments an opportunity for mutual action on issues of common interest.

    Full Text Available Background: Aging is one of the most serious problems that most developed countries are facing in the 21st century. In the European Union, Member States are responsible for the planning, funding and administration of health care and social protection systems. Local authorities and state governments should undertake research toward developing an appropriate array of community-based care services for old people. Objectives: This study analyses the regions of Slovenia for servicing old people in the 2000-2010 time horizon. Methods/Approach: Sets of functional regions were modelled for each year in the analysed period using the Intramax method. Functional regions were evaluated based on the attractiveness of central places for labour commuters and the propensity to commute between regions. Results: The results show that in addition to the nominally declared regional centres of Slovenia, there are also some other local centres that should be potentially included in the functional areas for servicing old people. Conclusions: The results suggest that the regionalization into seven functional regions is the most convenient for servicing old people in the region. Furthermore, some additional functional regions at a lower level are suggested.

    The hydrogeologic study covers an area of 50 km{sup 2} with the objectives of to determine the possibility of use of the underground waters and to locate places to carry out exploratory perforations in lands of Cafam, equally the elaboration of a hydrogeologic map of the region; for the effect it was carried out cartography geologic scale 1:10.000, inventory and sampling of water point, geoelectric prospecting and some permeability tests. In the area the exploitation of underground water is incipient, alone there are 20 points of water, of which none produce more than 1L/seg. The water has in general good physical chemistry quality for the human consumption. Geologically was recognized the groups Guadalupe and Gualanday, also some quaternary deposits; the previous ones were subdivided in 11 geological units for its composition and morphology, which are framed structurally in the E flank of the synclinal of Carmen de Apicala and displaced by traverse faults with address E-W and N-W. From the point of hydrogeologic view the units were grouped in 8 aquifer systems, of which four are considered of hydrogeologic importance for the area; the sector with better possibilities to capture these aquifer systems is the W of the area (in the terraces area) that extends to the Sumapaz River. For the Cafam sector a place was selected to build an exploratory well of 200 mts. of depth that would capture an aquifer of low transmissivity, corresponding to the Unit T3.

  6. Slunj-Plitvice Region: Chosen Dynamic and Structural Indicators of the Demographic Development of Rural Areas

    2009-09-01

    Full Text Available The Slunj-Plitvice region is a contact area between two Croatian counties: Karlovac County and Lika-Senj County. It can be defined in territorial-administrative terms as the area of the administrative Town of Slunj and the following municipalities: Cetingrad, Plitvička Jezera (Plitvice Lakes, Rakovica and Saborsko. The investigated region is located in the karst zone, which exerted a negative influence on demographic development in the past because of its geological, hydrological, pedological and geomorphologic characteristics. The entire researched region is predominantly rural. It is peripheral compared with the county centres Karlovac (Karlovac County and Gospić (Lika-Senj County. Therefore, the Slunj-Plitvice region can be described as an integral part of the negative population, economic and regional development pole of Croatia. The beginnings of the demographic crisis in the region date back from the first half of 20th century. During the 1990s, the already existing negative demographic circumstances were additionally worsened by Serbian armed aggression. The entire region suffered significant war casualties, migratory losses and material destruction. After liberation of the region, the process of reconstruction began. Its course has been very slow and marked by many obstacles. Because of the presence of the long-lasting, very negative demographic processes – total depopulation, natural depopulation, emigration depopulation and population ageing – the Slunj-Plitvice region has lost its ability to achieve demographic revitalisation. Population regeneration and renewal in the region will not be possible without the application of systematic stimulating measures for demographic and economic recovery. The demographic recovery plans must by all means include, besides pro birth-rate measures, stimulation for immigration of a young, predominately highly-educated population.

    Agria-Innoregion Knowledge Centre of the Eszterházy Károly College has carried out targeted basic researches in the field of renewable energy sources and climate change in the framework of TÁMOP-4.2.2.A-11/1/KONV project. The project has covered certain issues, which require the specific knowledge of the soil cover; for example: (i) investigation of quantitative and qualitative characteristics of natural and landscape resources; (ii) determination of local amount and characteristics of renewable energy sources; (iii) natural/environmental risk analysis by surveying the risk factors. The Energy Region Eger Research Model Area consists of 23 villages and is located in North-Hungary, at the Western part of Bükkalja. Bükkalja is a pediment surface with erosional valleys and dense river network. The diverse morphology of this area results diversity in soil types and soil properties as well. There was large-scale (1:10,000 and 1:25,000 scale) soil mappings in this area in the 1960's and 1970's which provided soil maps, but with reduced spatial coverage and not with fully functional thematics. To achive the recent tasks (like planning suitable/optimal land-use system, estimating biomass production and development of agricultural and ecomonic systems in terms of sustainable regional development) new survey was planned and carried out by the staff of the College. To map the soils in the study area 10 to 22 soil profiles were uncovered per settlement in 2013 and 2014. Field work was carried out according to the FAO Guidelines for Soil Description and WRB soil classification system was used for naming soils. According to the general goal of soil mapping the survey data had to be spatially extended to regionalize the collected thematic local knowledge related to soil cover. Firstly three thematic maps were compiled by digital soil mapping methods: thickness of topsoil, genetic soil type and rate of surface erosion. High resolution digital elevation model, Earth

    In the report, different aspects of environmental status of the Olkiluoto area, an island with the near-sea in the Finnish coast of the Baltic Sea, are described by five topical papers. Regarding animal-life, Olkiluoto represents a typical seashore area of southwestern Finland dominated by rocky hills and commercial forests. In the literature and interview study of local hunters, locally dominant mammal and bird species are identified. No threatened or endangered mammals species were found on the island, and only few bird species in Olkiluoto have a high conservation value. The sea area off Olkiluoto is rather shallow and the water mixing conditions are favourable. The quality and biological production of the water are affected by the general state of the Bothian Sea, the loading brought by the Eurajoki and Lapinjoki Rivers and local wastewaters. Also the cooling waters from the local nuclear power plant impact the sea environment. The bottom vegetation varies from an algae-dominant to a vascular-plantdominant community. Amount of benthic fauna and its species composition has varied considerably, due to both variations of the quality of the bottom and eutrophication. The Eurajoki River represents the second largest river system in southwestern Finland. At its upper reaches, the river is classified as clean and suitable for recreational use. Intermittently, additional waters rich in nutrients flow into the river from ditches and tributaries. Diffuse pollution and the wastewaters of riverside municipalities and industry affect on the water of the lower course, where it is only mildly contaminated, hygienically fairly good and satisfactory for recreational use. The benthic fauna of the river is composed of oligochaetes, clams, leeches and larvae. The fish reserve is versatile in places due to stocking. The Eurajoensalmi Strait, the inlet of the river, is a transitional zone between the river and further sea environments. In the offshore area facing Olkiluoto, there

  15. Towards regional, error-bounded landscape carbon storage estimates for data-deficient areas of the world.

    Directory of Open Access Journals (Sweden)

    Simon Willcock

    Full Text Available Monitoring landscape carbon storage is critical for supporting and validating climate change mitigation policies. These may be aimed at reducing deforestation and degradation, or increasing terrestrial carbon storage at local, regional and global levels. However, due to data-deficiencies, default global carbon storage values for given land cover types such as 'lowland tropical forest' are often used, termed 'Tier 1 type' analyses by the Intergovernmental Panel on Climate Change (IPCC. Such estimates may be erroneous when used at regional scales. Furthermore uncertainty assessments are rarely provided leading to estimates of land cover change carbon fluxes of unknown precision which may undermine efforts to properly evaluate land cover policies aimed at altering land cover dynamics. Here, we present a repeatable method to estimate carbon storage values and associated 95% confidence intervals (CI for all five IPCC carbon pools (aboveground live carbon, litter, coarse woody debris, belowground live carbon and soil carbon for data-deficient regions, using a combination of existing inventory data and systematic literature searches, weighted to ensure the final values are regionally specific. The method meets the IPCC 'Tier 2' reporting standard. We use this method to estimate carbon storage over an area of33.9 million hectares of eastern Tanzania, reporting values for 30 land cover types. We estimate that this area stored 6.33 (5.92-6.74 Pg C in the year 2000. Carbon storage estimates for the same study area extracted from five published Africa-wide or global studies show a mean carbon storage value of ∼50% of that reported using our regional values, with four of the five studies reporting lower carbon storage values. This suggests that carbon storage may have been underestimated for this region of Africa. Our study demonstrates the importance of obtaining regionally appropriate carbon storage estimates, and shows how such values can be produced

    Akiba, Suminori

    2012-01-01

    Below the doses of 100-200 mSv of radiation exposure, no acute health effect is observed, and the late health effects such as cancer are yet unclear. The problems making the risk evaluation of low dose radiation exposure difficult are the fact that the magnitude of expected health effects are small even if the risk is assumed to increase in proportion to radiation doses. As a result, studies need to be large particular when dealing with rare disease such as cancer. In addition, the expected health effects are so small that they can easily be masked by lifestyles and environmental factors including smoking. This paper will discuss cancer risk possibly associated with low-dose and low-dose rate radiation exposure, describing epidemiological studies on the residents in the high-background radiation areas.

    2008-01-01

    Environmental isotope techniques have been employed to identify the recharge areas of springs in India, in order to construct artificial recharge structures for rainwater harvesting and groundwater augmentation for their rejuvenation. A model project was taken up in the mountainous region of Gaucher area, Chamoli District, Uttarakhand for this purpose. The springs in this regions are seasonal and are derived from seepage waters flowing through the shallow weathered and fractured zone. The chemistry of high-altitude springs is similar to that of precipitation, whereas water-rock interactions contributes to increased mineralization in low-altitude springs. The stable isotopic variation in precipitation suggests that the altitude effect for Gaucher area is -0.55% for δ 18 O and -3.8% for δ 2 H per 100 m rise in altitude. Based on local geology, geomorphology, hydrochemistry and isotope information, the possible recharge areas inferred for valleys 1, 2 and 3 are located at altitudes of 1250, 1330 and 1020 m amsl respectively. Water conservation and recharge structures such as subsurface dykes, check bunds and contour trenches were constructed at the identified recharge areas in the respective valleys for controlling the subsurface flow, rainwater harvesting and groundwater augmentation respectively. As a result, during and after the following monsoon, the discharge rates of the springs not only increased significantly, but also did not dry up even during the dry period. The study shows that the isotope techniques can be effectively used in identifying recharge areas of springs in the Himalayan region. It also demonstrates the advantage of isotope techniques over conventional methods. (author)

  19. Evaluation of Tsunami Run-Up on Coastal Areas at Regional Scale

    González, M.; Aniel-Quiroga, Í.; Gutiérrez, O.

    2017-12-01

    Tsunami hazard assessment is tackled by means of numerical simulations, giving as a result, the areas flooded by tsunami wave inland. To get this, some input data is required, i.e., the high resolution topobathymetry of the study area, the earthquake focal mechanism parameters, etc. The computational cost of these kinds of simulations are still excessive. An important restriction for the elaboration of large scale maps at National or regional scale is the reconstruction of high resolution topobathymetry on the coastal zone. An alternative and traditional method consists of the application of empirical-analytical formulations to calculate run-up at several coastal profiles (i.e. Synolakis, 1987), combined with numerical simulations offshore without including coastal inundation. In this case, the numerical simulations are faster but some limitations are added as the coastal bathymetric profiles are very simply idealized. In this work, we present a complementary methodology based on a hybrid numerical model, formed by 2 models that were coupled ad hoc for this work: a non-linear shallow water equations model (NLSWE) for the offshore part of the propagation and a Volume of Fluid model (VOF) for the areas near the coast and inland, applying each numerical scheme where they better reproduce the tsunami wave. The run-up of a tsunami scenario is obtained by applying the coupled model to an ad-hoc numerical flume. To design this methodology, hundreds of worldwide topobathymetric profiles have been parameterized, using 5 parameters (2 depths and 3 slopes). In addition, tsunami waves have been also parameterized by their height and period. As an application of the numerical flume methodology, the coastal parameterized profiles and tsunami waves have been combined to build a populated database of run-up calculations. The combination was tackled by means of numerical simulations in the numerical flume The result is a tsunami run-up database that considers real profiles shape

  20. Hydrogeochemical studies of historical mining areas in the Humboldt River basin and adjacent areas, northern Nevada

    Nash, J. Thomas

    2005-01-01

    The study area comprises the Humboldt River Basin and adjacent areas, with emphasis on mining areas relatively close to the Humboldt River. The basin comprises about 16,840 mi2 or 10,800,000 acres. The mineral resources of the Humboldt Basin have been investigated by many scientists over the past 100 years, but only recently has our knowledge of regional geology and mine geology been applied to the understanding and evaluation of mining effects on water and environmental quality. The investigations reported here apply some of the techniques and perspectives developed in the Abandoned Mine Lands Initiative (AMLI) of the U.S. Geological Survey (USGS), a program of integrated geological-hydrological-biological-chemical studies underway in the Upper Animas River watershed in Colorado and the Boulder River watershed in, Montana. The goal of my studies of sites and districts is to determine the character of mining-related contamination that is actively or potentially a threat to water quality and to estimate the potential for natural attenuation of that contamination. These geology-based studies and recommendations differ in matters of emphasis and data collection from the biology-based assessments that are the cornerstone of environmental regulations.

    Full Text Available In the context of global warming, the changes in major lakes and their responses to the influence factors in arid and semi-arid regions along the Silk Road are especially important for the sustainable development of local water resources. In this study, the areas of 24 lakes were extracted using MODIS NDVI data, and their spatial-temporal characteristics were analyzed. In addition, the relationship between lake areas and the influence factors, including air temperature, precipitation, evapotranspiration, land use and land cover change (LULCC and population density in the watersheds, were investigated. The results indicated that the areas of most lakes shrank, and the total area decreased by 22,189.7 km2 from 2001 to 2016, except for those of the lakes located on the Qinghai-Tibetan Plateau. The air temperature was the most important factor for all the lakes and increased at a rate of 0.113 °C/a during the past 16 years. LULCC and the increasing population density markedly influenced the lakes located in the middle to western parts of this study area. Therefore, our results connecting lake area changes in the study region highlight the great challenge of water resources and the urgency of implementation of the green policy in the One Belt and One Road Initiative through international collaboration.

    Full Text Available Macro study is one approach that combines the rational method based on the results of previous studies by the authority with the empirical method utilizing the survey techniques. The purpose of this macro study is to identify and analyze the potentials, problems, and the limiting factors, and the needs of the regency; and to recommend the programs and models required by the community to achieve the sustainable development. This research uses the Participatory Rural Appraisal method, the  interview techniques (Semi Structured Interview, the technique of focused group discussion (FGD, the Rapid District Appraisal (RDA, then it is analyzed by the empirical and dynamical systems. The overview of macro studies is particularly relevant in developing the regions, especially the rural areas, based on the existing advantages, such as in Tabanan Regency. Tabanan Regency is a granary in Bali Province and the zoning of agricultural commodities in quadrant III,which is the rural farming area with combined functions between the cultivated and rural areas supported by the tourism department. The studies of the areas in the form of potential analysis, problem analysis, requirement analysis become the guidelines for preparing the development scenarios and program formats. The studies will then constitute the factors driving the realization of sustainable development of tourism villages in supporting the sustainable agriculture.

    The primary objective of this study is to present techniques that cover usage of a hydrodynamic model as the main tool for monitoring and assessment of flood events while focusing on modelling of inundation areas. We analyzed the 2010 flood event (14th May - 20th May) that occurred in the Moravian-Silesian region (Czech Republic). Under investigation were four main catchments: Opava, Odra, Olše and Ostravice. Four hydrodynamic models were created and implemented into the Floreon+ platform in order to map inundation areas that arose during the flood event. In order to study the dynamics of the water, we applied an unsteady flow simulation for the entire area (HEC-RAS 4.1). The inundation areas were monitored, evaluated and recorded semi-automatically by means of the Floreon+ platform. We focused on information about the extent and presence of the flood areas. The modeled flooded areas were verified by comparing them with real data from different sources (official reports, aerial photos and hydrological networks). The study confirmed that hydrodynamic modeling is a very useful tool for mapping and monitoring of inundation areas. Overall, our models detected 48 inundation areas during the 2010 flood event.

    Using the isotope techniques, the groundwater origin, evolution and circulation in the potential site of China's high-level waste repository are studied. The results indicate that both shallow groundwaters are and deep groundwaters in the site area are of meteoric origin. The shallow groundwaters are mainly recharged by modern and local precipitation, and the deep groundwaters are originated from regional history period with lower temperature. Through the study we can also understand that the deep underground is a very low-permeability system where the groundwater flow-rates are very low. (author)

    A new Brodmann area (BA) delineation approach was applied to FDG-PET scans of autistic patients and healthy volunteers (n = 17 in each group) to examine relative glucose metabolism (rGMR) during performance of a verbal memory task. In the frontal lobe, patients had lower rGMR in medial/cingulate regions (BA 32, 24, 25) but not in lateral regions (BA 8-10) compared with healthy controls. Patients had higher rGMR in occipital (BA 19) and parietal regions (BA 39) compared with controls, but there were no group differences in temporal lobe regions. Among controls, better recall and use of the semantic-clustering strategy was associated with greater lateral and medial frontal rGMR, while decreased rGMR in medial-frontal regions was associated with greater perseverative/intrusion errors. Patients failed to show these patterns. Autism patients have dysfunction in some but not all of the key brain regions subserving verbal memory performance, and other regions may be recruited for task performance. Copyright 2004 S.

    We calculated the three-dimensional (3D) distribution of the area expansion factors in a potential magnetic field, extrapolated from the high-resolution Hinode/SOT magnetogram of the quiescent active region NOAA 11482. Retaining only closed loops within the computational box, we show that the distribution of area expansion factors show significant structure. Loop-like structures characterized by locally lower values of the expansion factor are embedded in a smooth background. These loop-like flux tubes have squashed cross-sections and expand with height. The distribution of the expansion factors show an overall increase with height, allowing an active region core characterized by low values of the expansion factor to be distinguished. The area expansion factors obtained from extrapolation of the Solar Optical Telescope magnetogram are compared to those obtained from an approximation of the observed magnetogram by a series of 134 submerged charges. This approximation retains the general flux distribution in the observed magnetogram, but removes the small-scale structure in both the approximated magnetogram and the 3D distribution of the area expansion factors. We argue that the structuring of the expansion factor can be a significant ingredient in producing the observed structuring of the solar corona. However, due to the potential approximation used, these results may not be applicable to loops exhibiting twist or to active regions producing significant flares.

    Cesium-137 is an anthropogenic radionuclide introduced in the environment in the early of 1960s to the end of 1970s. The Cesium-137 has very used to assess soil redistribution in the landscape because this is very tight in the fine soil particles and its movement in the landscape is due to soil redistribution. To use Cesium-137 to assess soil redistribution is need to known the Cesium-137 inventory in an area that not has experimented soil erosion neither soil deposition. So, this work present Cesium-137 inventories in undisturbed areas in different regions of Brazil, from South to Northeast of Brazil. The inventories in these areas represent the variational deposition of Cesium-137 in the whole national territory of Brazil. The inventories of Cesium-137 varied from 200 +- 15 Bq.m{sup -2} for South region to 15 +- 2 Bq.m{sup -2} for Northeast region. Moreover, was verified that the Cesium- 137 inventories depend on latitude and altitude of the area. (author)

    Tono Geoscience Center, Japan Nuclear Cycle Development Institute has been conducting a wide range of geoscientific research in order to build firm scientific and technological basis for the research and development of geological disposal. One of the geoscientific research programme is a Regional Hydrogeological Study (RHS) project in the Tono region, central Japan. This report mainly summarizes the results of research in DH-14 and DH-15 boreholes at Toki city and Mizunami city in fiscal year 2004 which were carried out to support and improve the results in fiscal year 2003. The research in the regional scale area shows the reliability of conceptual hydrogeological model and numerical simulation for the evaluation of regional hydrogeology. On the other hand, the geological and geophysical investigation, and borehole investigation during the surface-based investigations in the local scale area provide the pragmatic distribution of hydrogeological structure that may control regional groundwater hydrology. Hydrogeological simulations regarding the geological structure such as fault and hydrogeological property demonstrate the priority of investigation of geological structure for the evaluation of hydrogeology. The fault perpendicular to groundwater flow direction crucially affects on regional hydrology. Such fault is necessary to be investigated by priority. Hydrochemical investigation shows that chemical evolution process in this groundwater illustrated is mixing between groundwaters with different salinities. Principal component analysis and mass balance calculation reveal reliable chemistry of end-member waters for mixing. Regarding methodology development, the strategy and procedure of investigations are summarized based on the results of surface-based investigation. Moreover the multi interval monitoring system for water pressure and temperature has developed and started to monitor the in-situ condition of groundwater.

    According to the European Environment Agency (EEA Report No 1/2016), a significant share of the European population is estimated to be living on or near a floodplain, with Italy having the highest population density in flood-prone areas among the countries analysed. This tendency, tied with event frequency and magnitude (e.g.: the 24/11/2016 floods in Italy) and the fact that river floods may occur at large scales and at a transboundary level, where data is often sparse, presents a challenge in flood-risk management. The availability of consistent flood hazard and risk maps during prevention, preparedness, response and recovery phases are a valuable and important step forward in improving the effectiveness, efficiency and robustness of evidence-based decision making. The present work aims at testing and discussing the usefulness of pattern recognition techniques based on geomorphologic indices (Manfreda et al., J. Hydrol. Eng., 2011, Degiorgis et al., J Hydrol., 2012, Samela et al., J. Hydrol. Eng., 2015) for the simplified mapping of river flood-prone areas at large scales. The techniques are applied to 25m Digital Elevation Models (DEM) of the Danube, Po and Severn river watersheds, obtained from the Copernicus data and information funded by the European Union - EU-DEM layers. Results are compared to the Pan-European flood hazard maps derived by Alfieri et al. (Hydrol. Proc., 2013) using a set of distributed hydrological (LISFLOOD, van der Knijff et al., Int. J. Geogr. Inf. Sci., 2010, employed within the European Flood Awareness System, www.efas.eu) and hydraulic models (LISFLOOD-FP, Bates and De Roo, J. Hydrol., 2000). Our study presents different calibration and cross-validation exercises of the DEM-based mapping algorithms to assess to which extent, and with which accuracy, they can be reproduced over different regions of Europe. This work is being developed under the System-Risk project (www.system-risk.eu) that received funding from the European Union

    Introduction Access to quality healthcare services is considered a moral right. However, for people living in regional locations, timely access to the services that they need may not always be possible because of structural and attitudinal barriers. This suggests that people living in regional areas may have unmet healthcare needs. The aim of this research will be to examine the healthcare needs, expectations and experiences of regional South Australians. Methods and analysis The Regional South Australia Health (RESONATE) survey is a cross-sectional study of adult health consumers living in any private or non-private dwelling, in any regional, rural, remote or very remote area of South Australia and with an understanding of written English. Data will be collected using a 45-item, multidimensional, self-administered instrument, designed to measure healthcare need, barriers to healthcare access and health service utilisation, attitudes, experiences and satisfaction. The instrument has demonstrated acceptable psychometric properties, including good content validity and internal reliability, good test–retest reliability and a high level of acceptability. The survey will be administered online and in hard-copy, with at least 1832 survey participants to be recruited over a 12-month period, using a comprehensive, multimodal recruitment campaign. Ethics and dissemination The study has been reviewed and approved by the Human Research Ethics Committee of the University of South Australia. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media, print media, the internet and various community/stakeholder engagement activities.

    This study was carried out to determine the effect of the industrial wastes on marine environment in Port Sudan area. A very intensive study has been made to identify types of pollutions drained in seawater at study area of Red Sea coast. Samples were taken from three stations (1, 2 and 3) at study area and the following analysis were made: Temperature, salinity, hydrogen ion concentration, dissolved oxygen, biochemical oxygen demand, nutrient, oil and grease. The laboratory results revealed that wastes pollute the marine environment as the cooling water from studied industries which is drain into the seawater increases the degree of temperature approximately from 6 to 12 C degree above the allowed rate, the matter which was adverse effect on the environment and living marine creatures due to the sudden change of temperature degree. Also, it was found that the great amount of oil spills discharged into seawater due to many factors such as: cooling water, oil spills from ships and loading and discharging operations of crude oil ships. Accordingly these oils spills might have a deadly effect on living marine creatures, which have been mention in details through out this research. Hence, and to minimize this adverse effect of industrial wastes and others on the marine environment, may recommend to the following: Pretreatment to the industrial wastes should be taking before its draining into the Red Sea coastal area. Surveillance all ships into the port and observing loading and discharging operations as well as those ships in the regional waters and implementing the international maritime laws. Enlightenment the industrial administrators and manpower working with them about the severity which will definitely cause the marine environmental deterioration as a result of industrial wastes. To punish every one who violates the laws of environment protection. Thus, can be safeguarding the environment from pollutions and consequently develop the natural resources and proceed

  16. Regional climate scenarios - A study on precipitation

    2001-01-01

    A set of nested climate change simulations for the Nordic region and Denmark has been revisited. In the present work we have re-examined the results of CCMB and MBC with special emphasis on precipitation intensity frequencies, in particular the more extreme part of the frequency distribution. It has been demonstrated that the role of extreme precipitation events appears to be more realistically described in a high-resolution model, in terms of numerical agreement as well as seasonal variation. This is mainly due to a better simulation of deep low-pressure systems and mesoscale circulation. Generally, the analysis has confirmed the results from CCMB, but furthermore a resolution effect has been identified which seems essential to the understanding of climate change effects on the extreme end of the precipitation intensity distribution. In order to analyse the role of the model resolution we have aggregated both the nested model data and observational records to the GCM grid from the driving AOGCM. It was found that, in spite of changes in absolute numbers, the seasonal behaviour of decay constants does not change appreciably because of the aggregation. The RCM results show a seasonal behaviour very similar to an observed data set. It is therefore concluded that the GCM has an unrealistic simulation of the dependence of heavy precipitation on climate, as manifested in seasonal variation. In contrast, the regional simulations remain close to observation in this respect. Furthermore, they agree on a conclusion that extreme precipitation generally scales with average precipitation (no significant change in decay constants were detected), but that crucial summer season may be an exception, exhibiting an anomalous increase in heavy precipitation due to the anthropogenic greenhouse effect. The analysis has only been performed over Denmark due to lack of daily observational data for other regions. It is, however, necessary to extend the work to other areas, for instance

    Leaf area index (LAI) is an important vegetation parameter that characterizes leaf density and canopy structure, and plays an important role in global change study, land surface process simulation and agriculture monitoring. The wide field view (WFV) sensor on board the Chinese GF-1 satellite can acquire multi-spectral data with decametric spatial resolution, high temporal resolution and wide coverage, which are valuable data sources for dynamic monitoring of LAI. Therefore, an automatic LAI estimation algorithm for GF-1 WFV data was developed based on the radiative transfer model and LAI estimation accuracy of the developed algorithm was assessed in an agriculture region with maize as the dominated crop type. The radiative transfer model was firstly used to simulate the physical relationship between canopy reflectance and LAI under different soil and vegetation conditions, and then the training sample dataset was formed. Then, neural networks (NNs) were used to develop the LAI estimation algorithm using the training sample dataset. Green, red and near-infrared band reflectances of GF-1 WFV data were used as the input variables of the NNs, as well as the corresponding LAI was the output variable. The validation results using field LAI measurements in the agriculture region indicated that the LAI estimation algorithm could achieve satisfactory results (such as R² = 0.818, RMSE = 0.50). In addition, the developed LAI estimation algorithm had potential to operationally generate LAI datasets using GF-1 WFV land surface reflectance data, which could provide high spatial and temporal resolution LAI data for agriculture, ecosystem and environmental management researches.

    The assessment of remediation measures for rural areas is more complex than that for urban ones, due to the influence of large number of variables associated with climate, diet, farming practices and the type of soil. Thus, it is not possible to perform generic studies applicable to all types of area. Specific studies and surveys should be made in the areas most likely to contamination from a nuclear accident. Preliminary studies demonstrated that the different soil types in Brazil is more relevant to the ingestion dose than the regional differences in diets. Other studies have described the prioritization of areas and products for detailed survey on soil types and remediation procedures, for an accident at the NPP in Angra dos Reis, based on radiological and economic aspects. The most relevant product was milk, due to both its relevance to the intake and the loss of income for the counties. The contribution of milk to dose depends on the season of the year when the accident occurs, mainly due to the relative contribution of other items of the diet. The timing of the application of the countermeasure has an important effect on the dose reduction that can be achieved. For I-131, protective measures must be considered within the emergency phase in order to be effective. The main action on reducing ingestion doses is the removal of food items from diet, while providing clean food to the population. (author)

    A study on the sediment size distribution and determination of sediment density profile in the selected area of Muda dam catchment area, Kedah is presented. The objective of the study was to establish a base line data of the input sedimentation with regards to the effects of development within the catchment in the future. Three main sampling locations were identified namely at Sungai Teliang, Sungai Muda and Muda reservoir. Measurement of sediment thickness was performed by using nuclear gauges i.e. direct transmission and backscattering methods. Results showed that the grain size distribution of sediment ranges from gravel to clay sizes. In the reservoir and downstream of the river, most of the samples studied consisting of fine sediment i.e silt and clay sizes (<63,um). However, sediment distribution in the upstream section of Sungai Teliang mainly consist of fine to coarse sand. Sediment density profiles in the reservoir showed little changes, whereas bed sediment profiles in the river cross-sectional areas exhibit some changes. The results also showed that thickness of bedload sediment were different from one location to another, in which the thickness may achieve up to 0.75 metre in some areas. Based on the sediment distribution profile analysis, the study site could be divided into two parts comprising of dynamic area (region) covering selected locations along the river and deposited sediment in the reservoir. Basic information derived from this study may provide as one of the important inputs for the MADA reservoir management authority in monitoring, supervising y and identifying rate and source of sediment in the catchment area

  2. Estimating External Costs of Transportation in Regional Areas: Using Available Statistical Data the Case of the Region of Campania

    Directory of Open Access Journals (Sweden)

    2010-04-01

    Full Text Available In this paper simplified methods for estimating the external costs due to transportation in regional areas are proposed. The methods are based on data available by national and regional statistical sources and do not need specific surveys; they allow obtaining approximate estimates useful for a preliminary evaluation of transportation plans, policies and projects. In more detail, a negative externality is defined as a cost that is produced by subject A and is borne by subject B; moreover, subject A does not consider the effects of his/her behavior on subject B and does not compensate subject B for the costs that this last one is forced to bear. In this paper after a literature review on methodologies proposed for estimating external costs, in national and international ambits, the main external costs produced by transportation systems in the Region of Campania are estimated. The main external costs considered are: greenhouse gas emissions, air pollution, noise, accidents and congestion. In the paper the secondary external costs are neglected; the main ones are: water and soil pollution; landscape and nature damages; upstream and downstream effects; visual intrusion; separation effects; soil occupancy. In this paper the external costs estimated are the ones produced not only by road traffic, that anyway is the main “culprit”, but also by rail and air transportation systems. The evaluation of external costs has required the collection of several data on the regional mobility and the estimation of veh-kms per year produced in Campania by cars and freight vehicles. The estimation of veh-kms per year is based on circulating vehicles, subdivided by the COPERT classification, and on average yearly distances covered by each vehicle class. Other regional statistical data are collected about regional rail transport and air services at the main airports of the region. Moreover, since the evaluation of some external costs is based on damages on human

    Results of geophysical studies in the Clear Lake region of California, north of San Francisco, have revealed a prominent, nearly circular negative gravity anomaly with an amplitude of more than 25 milligals (mgal) and an areal extent of approximately 250 square miles and, in addition, a number of smaller positive and negative anomalies. The major negative gravity anomaly is closely associated with the Clear Lake volcanic field and with an area characterized by hot springs and geothermal fields. However, the anomaly cannot be explained by mapped surface geologic features of the area. Aeromagnetic data in the Clear Lake region show no apparent correlation with the major negative gravity anomaly; the local magnetic field is affected principally by serpentine. An electrical resistivity low marks the central part of the gravity minimum, and a concentration of earthquake epicenters characterizes the Clear Lake volcanic field area. The primary cause of the major negative gravity anomaly is believed to be a hot intrusive mass, possibly a magma chamber, that may underlie the Clear Lake volcanic field and vicinity. This mass may serve as a source of heat for the geothermal phenomena in the area. Other smaller gravity anomalies in the Clear Lake region are apparently caused by near-surface geologic features, including relatively dense units of the Franciscan Formation and less dense Cenozoic sedimentary and volcanic rock units.

    To study the ecological suitability regionalization of Eucommia ulmoides, for selecting artificial planting base and high-quality industrial raw material purchase area of the herb in Guizhou. Based on the investigation of 14 Eucommia ulmoides producing areas, pinoresinol diglucoside content and ecological factors were obtained. Using spatial analysis method to carry on ecological suitability regionalization. Meanwhile, combining pinoresinol diglucoside content, the correlation of major active components and environmental factors were analyzed by statistical analysis. The most suitability planting area of Eucommia ulmoides was the northwest of Guizhou. The distribution of Eucommia ulmoides was mainly affected by the type and pH value of soil, and monthly precipitation. The spatial structure of major active components in Eucommia ulmoides were randomly distributed in global space, but had only one aggregation point which had a high positive correlation in local space. The major active components of Eucommia ulmoides had no correlation with altitude, longitude or latitude. Using the spatial analysis method and statistical analysis method, based on environmental factor and pinoresinol diglucoside content, the ecological suitability regionalization of Eucommia ulmoides can provide reference for the selection of suitable planting area, artificial planting base and directing production layout.

    Full Text Available The transmission of sound in a duct with sudden area expansion and extended inlet is investigated in the case where the walls of the duct lie in the finite overlapping region lined with acoustically absorbent materials. By using the series expansion in the overlap region and using the Fourier transform technique elsewhere we obtain a Wiener-Hopf equation whose solution involves a set of infinitely many unknown expansion coefficients satisfying a system of linear algebraic equations. Numerical solution of this system is obtained for various values of the problem parameters, whereby the effects of these parameters on the sound transmission are studied.

  11. Region-to-area screening methodology for the crystalline repository project

    International Nuclear Information System (INIS)

    1984-08-01

    The ''Nuclear Waste Policy Act of 1982'' (NWPA), enacted January 7, 1983 as Public Law 97-425, confirmed the responsibility of the US Department of Energy (DOE) for management of high-level radioactive waste. The NWPA directed the DOE to provide safe facilities for isolation of high-level radioactive waste from the environment in federally owned and federally licensed repositories. To achieve the goals of providing licensed repositories for high-level radioactive waste, a technical program has been developed by the DOE to meet all relevant radiological protection criteria and other requirements. By March 1987, the NWPA requires the DOE to recommend to the President a single site, chosen from five nominated sites for construction of the first repository. Rock types being considered as potential hosts for the first repository include salt, basalt, and tuff. The NWPA also requires the DOE to select three candidate sites, chosen from five nominated sites to be recommended to the President by July 1989, as possible locations for the second repository. Potential host rock types for the second federal repository will include crystalline rock. This document outlines the methodology for region-to-area screening of exposed crystalline rock bodies for suitability as sites for further study. 17 refs., 14 figs., 2 tabs

    Cortical thickness (CT) and surface area (SA) are altered in many neuropsychiatric disorders and are correlated with cognitive functioning. Little is known about how these components of cortical gray matter develop in the first years of life. We studied the longitudinal development of regional CT and SA expansion in healthy infants from birth to 2 years. CT and SA have distinct and heterogeneous patterns of development that are exceptionally dynamic; overall CT increases by an average of 36.1%, while cortical SA increases 114.6%. By age 2, CT is on average 97% of adult values, compared with SA, which is 69%. This suggests that early identification, prevention, and intervention strategies for neuropsychiatric illness need to be targeted to this period of rapid postnatal brain development, and that SA expansion is the principal driving factor in cortical volume after 2 years of age. © The Author 2014.

    Studying the geographical distribution of indoor radon concentration, using geostatistical interpolation methods, has become common for predicting and estimating the risk to the population. Here we analyse the case of Friuli Venezia Giulia (FVG), the north easternmost region of Italy. Mean value and standard deviation are, respectively, 153 Bq/m(3) and 183 Bq/m(3). The geometric mean value is 100 Bq/m(3). Spatial datasets of indoor radon concentrations are usually affected by clustering and apparent non-stationarity issues, which can eventually yield arguable results. The clustering of the present dataset seems to be non preferential. Therefore the areal estimations are not expected to be affected. Conversely, nothing can be said on the non stationarity issues and its effects. After discussing the correlation of geology with indoor radon concentration It appears they are created by the same geologic features influencing the mean and median values, and can't be eliminated via a map-based approach. To tackle these problems, in this work we deal with multiple definitions of RPA, but only in quaternary areas of FVG, using extensive simulation techniques. Copyright © 2014 Elsevier Ltd.

    2010-04-01

    Full Text Available Tam Dao National Park (TDNP is a remaining primary forest that supports some of the highest levels of biodiversity in Vietnam. Forest conversion due to illegal logging and agricultural expansion is a major problem that is hampering biodiversity conservation efforts in the TDNP region. Yet, areas vulnerable to forest conversion are unknown. In this paper, we predicted areas vulnerable to forest changes in the TDNP region using multi-temporal remote sensing data and a multi-layer perceptron neural network (MLPNN with a Markov chain model (MLPNN-M. The MLPNN-M model predicted increasing pressure in the remaining primary forest within the park as well as on the secondary forest in the surrounding areas. The primary forest is predicted to decrease from 18.03% in 2007 to 15.10% in 2014 and 12.66% in 2021. Our results can be used to prioritize locations for future biodiversity conservation and forest management efforts. The combined use of remote sensing and spatial modeling techniques provides an effective tool for monitoring the remaining forests in the TDNP region.

    Carbon isotope analysis of four baobab (Adansonia digitata L.) trees from the Pafuri region of South Africa yielded a 1000-year proxy rainfall record. The Pafuri record age model was based on 17 radiocarbon dates, cross correlation of the climate record, and ring structures that were presumed to be annual for two of the trees. Here we present the analysis of five additional baobabs from the Mapungubwe region, approximately 200km west of Pafuri. The Mapungubwe chronology demonstrates that ring structures are not necessarily annually formed, and accordingly the Pafuri chronology is revised. Changes in intrinsic water-use efficiency indicate an active response by the trees to elevated atmospheric CO2, but this has little effect on the environmental signal. The revised Pafuri record, and the new Mapungubwe record correlate significantly with local rainfall. Both records confirm that the Medieval Warm Period was substantially wetter than present, and the Little Ice Age was the driest period in the last 1000 years. Although Mapungubwe is generally drier than Pafuri, both regions experience elevated rainfall peaking between AD 1570 and AD 1620 after which dry conditions persist in the Mapungubwe area until about AD 1840. Differences between the two records correlate with Agulhas Current sea-surface temperature variations suggesting east/west displacement of the temperate tropical trough system as an underlying mechanism. The Pafuri and Mapungubwe records are combined to provide a regional climate proxy record for the northern summer rainfall area of southern Africa.

    This dissertation is an integrated study of basins in the four corners area of the central part of the Colorado Plateau. The Colorado Plateau is a structurally unique part of the Rocky Mountain region because it has only been moderately deformed when compared to the more intensely deformed areas around it. The Colorado Plateau covers a portion of Utah, Colorado, New Mexico and Arizona. The study area extends from latitude 34°N-40°N to longitude 106°W-111W° encompassing a series of major basins and uplifts: the San Juan, Black Mesa, Paradox, and the Blanding basins; and the Zuni, Defiance, Four Corners, Monument uplifts and the San Juan dome and volcanic field. An analysis of gravity anomalies, basement and crustal structure for basins in the four corners region was carried out. This involved using gravity, magnetic, well, outcrop, seismic estimates of crustal thickness, and geologic data in an integrated fashion. Six filtered gravity and three filtered magnetic maps were generated to aid in the interpretation of the gravity and magnetic anomalies in the study area. A detailed comparison of these maps was carried out. The results show a deep seated mafic structure in the basement acting as a crustal boundary separating the high gravity anomalies from the low. These maps also show that the sources of these anomalies are quite shallow resulting from the upper crust in the study area. The structures in the study area are characterized by northwest and northeast trends which correspond to the Precambrian and the Late Paleozoic structures, respectively. A crustal thickness map of the area was also constructed from seismic estimates of crustal thickness. A comparison was done between the crustal thickness map and the 45 km upward continuation Bouguer anomaly map. The result of this comparison shows that areas of thicker ix crust corresponded to low gravity while areas of thinner crust means mantle material is closer to the surface, thereby producing a high gravity

    Full Text Available The objective of this study is the history of skiing, while the main goal will be the historical development of skiing in the mountain Durmitor area in Montenegro. The study consists two goals. The first goal is the emergence of the first ski in the Montenegro and benefits that are brought. The second and the main goal is the occurrence and development of skiing and ski sports in the territory of mountain Durmitor. During the making of this study, the authors used descriptive method with consulting of competent literature. The previous authors’ experience in this field was also so useful. Moreover, the author used the analytic method and parallel method that is the most productive if you make some inferences about some appearance. The main outcome of this study was showing of historical progress of ski sports in the territory of mountain Durmitor from early beginnings to the modern Olympic skiing. Skis and ski sport were early appeared in the region of Mount Durmitor. The mountain and the region around it, are very rich with slopes with Olympic diameter, with plenty of snowfall and long winters. However, lack of financial investment, channeling money to other centers, led to the fact that the skiing in this area is at a low level.

    As nuclear research has become more prevalent, environmental contamination from the disposal of radioactive waste has become a prominent issue. At Los Alamos National Laboratory (LANL) in northern New Mexico, radioactive contamination from disposal operations has raised some very specific concerns. Material Disposal Area G (Area G) is the primary low-level radioactive waste disposal site at LANL and occupies an area adjacent to land belonging to the Native American community of the Pueblo of San Ildefonso. Analyses of soil and vegetation collected from the perimeter of Area G have shown concentrations of radionuclides greater than background concentrations established for northern New Mexico. As a result, Pueblo residents had become concerned that contaminants from Area G could enter tribal lands through various ecological pathways. The residents specifically questioned the safety of consuming meat from elk and deer that forage near Area G and then migrate onto tribal lands. Consequently, this study addresses the uptake of {sup 3}H, {sup 90}Sr, {sup tot}U, {sup 238}Pu, {sup 239}Pu, {sup 241}Am, and {sup 137}Cs by elk (Cervus elaphus) and deer (Odocoileus hemionus) that forage around the perimeter of Area G and the associated doses to the animals and to humans who consume these animals. Radionuclide uptake by and internal dose to animals was estimated using equations modified from National Council on Radiological Protection Report 76. The Residual Radiation computer code was used to estimate the external dose to animals and the dose to humans consuming meat. Soil and water concentrations from the perimeter of Area G and from background regions in northern New Mexico were averaged over 4 years (1993--1996) and used as input data for the models. Concentration estimates generated by the model correspond to the concentration range measured in actual tissue samples from elk and deer collected at LANL.

    The sizes and number of cities in China are increasing rapidly and complicated changes of urban land use system have occurred as the social economy develops rapidly. This study took the urban agglomeration of Pearl River Delta Region as the study area to explore the driving mechanism of dynamic changes of urban area in the urbanization process under the joint influence of natural environment and social economic conditions. Then the CA (cellular automata) model was used to predict and simulate the urban area changes until 2030 under the designed scenarios of planning and RCPs (representative concentration pathways). The results indicated that urbanization was mainly driven by the non-agricultural population growth and social-economic development, and the transportation had played a fundamental role in the whole process, while the areas with high elevation or steep slope restricted the urbanization. Besides, the urban area would keep an expanding trend regardless of the scenarios, however, the expanding speed would slow down with different inflection points under different scenarios. The urban expansion speed increased in the sequence of the planning scenario, MESSAGE scenario and AIM scenario, and that under the MESSAGE climate scenario was more consistent with the current urban development trend. In addition, the urban expansion would mainly concentrate in regions with the relatively high urbanization level, e.g., Guangzhou, Dongguan, Foshan, Shenzhen, Zhanjiang and Chaoshan.

    International Atomic Energy Agency (IAEA) carried out the Co-ordinated Research Program (CRP) ON V alidation of Accident and Safety Analysis Methodology'' in the period between 1995 and 1998. Three areas of interest identified by the participants referred to the pressurised water reactors of Western and Eastern type (PWR and WWER type). The specific areas of attention were: system behaviour of the primary and secondary loops (PS area), the containment response (CO area) and the severe accidents (SA area). During the CRP it became clear that the technology advancements, the available tools (i.e. codes) and the experimental databases in the above areas are quite different. At the conclusion of the CRP, all objectives of the program have been reached. This paper presents the summary of the regional co-operation in this framework. The CRP activities focused on the codes and expertise available at the participating organisations. This overview therefore summarises their experience related to the state-of-the-art in the field of computational accident analysis. In addition, the paper proposes the recommendations for future activities related to the code usage, the user effects and code development. In pursuing of these goals special attention is given to the importance of the international co-operation. (author)

  6. Hydrogeology of rocks of low permeability: region studies

    Llamas, M.R.

    1985-01-01

    Hydrogeological regional studies on low permeability rocks are rather scarce in comparison to similar studies on normal permeability rocks. Economic and technological difficulties to develop ground water from these terrains may be the main cause of this scarcity. Several facts may indicate that these studies will increase in the near future. First, the need to supply water to the people living in underdeveloped arid zones over extensive areas of low permeability rocks. Second, the relevant role that some low permeability large groundwater basins may play in conjunctive ground and surface-water use. And last but not least the feasibility of some low permeability rock areas as sites for nuclear waste repositories. Some specific difficulties in these regional studies may be: a) intrinsic difficulties in obtaining representative water samples and measuring hydraulic heads; b) scarcity of observation and/or pumping wells; c) important hydraulic head and chemical properties variations in a vertical direction; d) old groundwater ages; this may require paleohydrological considerations to understand certain apparent anomalies. In most of these regional studies hydrogeochemical methods and modelling (flow and mass transport) may be very valuable tools. 77 references, 7 figures

    A sero-epidemiological study of myxomatosis, realized in the region of Monastir, confirmed the existence and the prevalence of the disease in its nodular form. Different strains of the myxomatosis virus were isolated and identified by gel immunodiffusion test (GID) using specific polyclonal sera. Serological analyses using complement fixation (FC) and (GID) tests allowed the detection of specific antibodies in sera from both healthy and sick animals. The results also confirmed the better sensitivity of the FC over the GID. Overall rates infection of herds and animals were 54.9% and 32.63% (p myxomatosis cases suggests that the disease first appeared in the coastal region then moved inside the Sabel area. Breeding and farming conditions, associated with deficiency in sanitary and medical measures, are at the origin of the introduction and the wide distribution of myxomatosis in this region.

    Six healthy controls, seven patients with coronary heart disease (CHD), and five patients with exercise-induced asthma (EIA) were studied in the sitting position at rest and during maximum exercise. The radionuclide gold-195m was used in the studies. A redistribution of activity toward the lung apex was found during exercise, the change being more pronounced in the healthy controls than in the patients with CHD. In two of the three patients in which exercise induced an asthmatic attack, gross reductions in the activity were seen in different areas of the lung. The authors conclude that gold-195m can be used for studies of rapid changes in regional pulmonary circulation

    The present study aimed at mapping some categories of Areas of Permanent Preservation (APP) for natural regeneration of semideciduous forests in the regions of Zona da Mata and Campo das Vertentes, Minas Gerais State (Figure 1), and from this to establish what impact the deployment of APP over area of pastures and subsequently milk production and carbon sequestration, considering areas of pasture as one of major factors for the dairy farming in the regions concerned. From the altimetric information from MDE, it was possible to extract morphological and morphometrical data to estimate the areas of APP. We used imagery of MODIS/Terra for extraction of the pastures areas from the vegetation index data NDVI to intersect with the estimated area of APP. In a linear or deterministic scenario of deployment of APPs over in the pasture areas considering that wich are proportionately responsible for sizing the herd, and thus for the milk production in extensive livestock, despite the existence of numerous other factors, there would be an impact 12% in the production of Campo das Vertentes region and 21.5% for the Zona da Mata. In this scenario, according to the carbon balance of forests and livestock, there would be a positive balance with the deployment of areas of permanent preservation and, subsequent promotion of natural regeneration. Considering the current grazing area of the Zona da Mata and Campo das Vertentes, 1.6 million hectares, with the carbon balance estimated at 1 ton/hectare/year, 300,000 hectares would have a balance of 5 ton/hectare/year in whole cycle of 40 years, totaling 200 tons carbon by hectare, or additional 48 million tons fixed, considering 4 tons more than pastures in the case of semideciduous forest. At the end of the cycle or forest climax, there would still be positive carbon balance, estimated as a balance of 2 ton/hectare/year. However, despite the higher carbon balance for the semideciduous forest, compared to livestock, it is important to

    The geographical position of Indonesia located between two continents and oceans is strategic, but at large risk of experiencing various disasters. Climate change and vulnerable location (surrounded by plates and geological faults in the Earth's crust) creates an earthquake-prone region and causes land/mudslides. In this paper, PS InSAR method (Persistent Scatterer Interferometric Synthetic Aperture Radar) is implemented to Phased Array type L-band Synthetic Aperture Radar (PALSAR) data to study the potential damage caused by the earthquake or volcanic eruption in Malang vicinity. By comparing the amplitude images periodically, shifting soil can be determined using precise orbital information. The analysis showed a significant decrease of land deformation on slope area in Klojen district in Malang city, reached up to −7.128 mm/year

    The spatial extent of transcranial magnetic stimulation (TMS) is of paramount interest for all studies employing this method. It is generally assumed that the induced electric field is the crucial parameter to determine which cortical regions are excited. While it is difficult to directly measure the electric field, one usually relies on computational models to estimate the electric field distribution. Direct electrical stimulation (DES) is a local brain stimulation method generally considered the gold standard to map structure-function relationships in the brain. Its application is typically limited to patients undergoing brain surgery. In this study we compare the computationally predicted stimulation area in TMS with the DES area in six patients with tumors near precentral regions. We combine a motor evoked potential (MEP) mapping experiment for both TMS and DES with realistic individual finite element method (FEM) simulations of the electric field distribution during TMS and DES. On average, stimulation areas in TMS and DES show an overlap of up to 80%, thus validating our computational physiology approach to estimate TMS excitation volumes. Our results can help in understanding the spatial spread of TMS effects and in optimizing stimulation protocols to more specifically target certain cortical regions based on computational modeling.

    To find out to what extent nurses were perceived to be participating in audit, to identify factors thought to impede their involvement, and to assess progress towards multidisciplinary audit. Qualitative. Focus groups and interviews. Chairs of audit groups and audit support staff in hospital, community and primary health care and audit leads in health authorities in the North West Region. In total 99 audit leads/support staff in the region participated representing 89% of the primary health care audit groups, 80% of acute hospitals, 73% of community health services, and 59% of purchasers. Many audit groups remain medically dominated despite recent changes to their structure and organisation. The quality of interprofessional relations, the leadership style of the audit chair, and nurses' level of seniority, audit knowledge, and experience influenced whether groups reflected a multidisciplinary, rather than a doctor centred approach. Nurses were perceived to be enthusiastic supporters of audit, although their active participation in the process was considered substantially less than for doctors in acute and community health services. Practice nurses were increasingly being seen as the local audit enthusiasts in primary health care. Reported obstacles to nurses' participation in audit included hierarchical nurse and doctor relationships, lack of commitment from senior doctors and managers, poor organisational links between departments of quality and audit, work load pressures and lack of protected time, availability of practical support, and lack of knowledge and skills. Progress towards multidisciplinary audit was highly variable. The undisciplinary approach to audit was still common, particularly in acute services. Multidisciplinary audit was more successfully established in areas already predisposed towards teamworking or where nurses had high involvement in decision making. Audit support staff were viewed as having a key role in helping teams to adopt a

    Full Text Available Many studies have reported the thermal effects of urban expansion from non-built-up land; however, how changes in building height in built-up land influence the regional thermal environment is still uncertain. Thus, taking the transitional region between the Chinese megacities of Beijing and Tianjin as the study area, this study investigated the impacts of built-up land expansion in 2D and 3D on regional land surface temperature (LST. The expansion in 2D refers to the conversion from non-built-up land to built-up land, whereas the expansion in 3D characterized the building height change in the built-up land, referring to the conversion from low- and moderate-rise building (LMRB to high-rise building (HRB lands. The land use change from 2010 to 2015 was manually interpreted from high spatial resolution SPOT5 and Gaofen2 images, and the LST information in the corresponding period was derived from Landsat5/8 thermal images using an image-based method. The results showed that between 2010 and 2015, approximately 87.25 km2 non-built-up land was transformed to built-up land, and 13.21 km2 LMRB land was built into HRB land. These two types of built-up land expansions have induced opposing thermal effects in regard to regional surface temperature. The built-up land expansions from cropland and urban green land have raised the regional LST. However, the built-up land expansion from LMRB to HRB lands has induced a cooling effect. Thus, this study suggested that for the cooling urban design, the building height should also be considered. Furthermore, for future studies on thermal impacts of urbanization, it should be cautioned that, besides the urban area expansion, the building height change should also be emphasized due to its potential cooling effects.

    The Regional Sustainable Development Strategy (RSDS) builds on the current environmental and resource management system in Alberta, and it features a framework for: providing support for continued economic development in the region that addresses environmental needs and resource sustainability; creating an enhanced management framework that will adapt to the changing needs of the area which will guide government environmental and resource managers; developing a strong foundation of environmental information and science to assist in making decisions on sustainable resource and environmental management in the region; and creating a way to identify priority regional environmental issues and to organize the science and monitoring work needed to comprehend those issues. Blueprints for action were identified to attack issues within three group categories. The first category, which is based on information gaps and urgency, includes sustainable ecosystems, cumulative impacts on wildlife, soil and plant species diversity, effects of air emissions on human health, wildlife and vegetation, and bioaccumulation of heavy metals. The second category, which is based on information gaps and work underway, includes access management, cumulative impacts on fish habitat and populations, effects of tailings ponds emissions, effects of acid deposition on sensitive receptors, and impacts on surface water quality. The third category, which is based on information gaps, work underway and lower level of urgency, includes end pit lake water quality, impacts on surface water quantity, and impacts on groundwater quantity and quality

    Full Text Available The World Health Organization (WHO Western Pacific Region has established specific measles elimination surveillance indicators. There has been concern in Australia that these indicators may be too stringent and that measles elimination can occur without all surveillance prerequisites being met, in particular the minimum fever and rash clinician-suspected measles reporting rate with subsequent laboratory exclusion of measles. A regional public health unit in northern New South Wales, Australia, prompted local general practitioners to report fever and rash presentations that met the measles case definition or that they considered to be clinical measles. These notifications from July 2006 to June 2008 were reviewed to determine whether measles indicators for monitoring progress towards measles elimination could be achieved in Australia. Results confirmed that the surveillance indicators of “>2 reported suspected measles cases per 100 000 population,” “at least 80% of suspected cases adequately investigated within 48 hours” and “greater than 80% of cases had adequate blood samples collected” could be met. Only half the cases had virology that would allow genotyping of measles virus. Special efforts to engage and convince Australian medical doctors about the public health value of reporting clinically suggestive measles cases and collecting confirmatory blood tests, resulted in the current WHO Western Pacific Region indicators for progress towards measles elimination being met in a regional area of Australia.

  2. Global projections of 21st century land-use changes in regions adjacent to Protected Areas.

    Directory of Open Access Journals (Sweden)

    Linda J Beaumont

    Full Text Available The conservation efficiency of Protected Areas (PA is influenced by the health and characteristics of the surrounding landscape matrix. Fragmentation of adjacent lands interrupts ecological flows within PAs and will decrease the ability of species to shift their distribution as climate changes. For five periods across the 21(st century, we assessed changes to the extent of primary land, secondary land, pasture and crop land projected to occur within 50 km buffers surrounding IUCN-designated PAs. Four scenarios of land-use were obtained from the Land-Use Harmonization Project, developed for the Intergovernmental Panel on Climate Change's Fifth Assessment Report (AR5. The scenarios project the continued decline of primary lands within buffers surrounding PAs. Substantial losses are projected to occur across buffer regions in the tropical forest biomes of Indo-Malayan and the Temperate Broadleaf forests of the Nearctic. A number of buffer regions are projected to have negligible primary land remaining by 2100, including those in the Afrotropic's Tropical/Subtropical Grassland/Savanna/Shrubland. From 2010-2050, secondary land is projected to increase within most buffer regions, although, as with pasture and crops within tropical and temperate forests, projections from the four land-use scenarios may diverge substantially in magnitude and direction of change. These scenarios demonstrate a range of alternate futures, and show that although effective mitigation strategies may reduce pressure on land surrounding PAs, these areas will contain an increasingly heterogeneous matrix of primary and human-modified landscapes. Successful management of buffer regions will be imperative to ensure effectiveness of PAs and to facilitate climate-induced shifts in species ranges.

    In 1970 the Phytotoxicology Section of the Air Management Branch initiated a pre-pollution background survey of the environmental situation in the Timmins area where Texas Gulf Sulphur was expected to construct an electrolytic zinc refinery near Hoyle (12 miles northeast of Timmins). In April 1972, the refinery began production, and during the 1972 growing season this new plant operated at a rate of 70 to 90% of the theoretical capacity. The refinery is located adjacent to the ore concentrator which has been operative since November 1966. During 1970, 1971, and 1972, Phytotoxicology personnel conducted an extensive program of environmental analysis and evaluation in the area. The information gathered to date indicates that within a 20 mile radius of the refinery, the condition of the vegetation (trees, shrubs, and ground flora) is similar to that existing in the control areas (number of species, number of plants, growth rate, crown condition etc.) which are located 50 miles from Hoyle. The lead peroxide candle survey showed that only background levels of sulfur dioxide were present in the ambient air both before and after the initiation of operations at the refinery. No SO/sub 2/ injury to vegetation has been observed in the Hoyle area. Chemical analysis of the vegetation, soil, and water samples collected at twelve established plots in 1971 shows elevated levels of metals in the soil immediately to the east and northeast of Hoyle. These same metals were elevated also in the vegetation collected at plots 1 and 2, close to the plant. Further work is planned to determine the source of this contamination. 13 tables.

    Full Text Available Objectives: Describe computed tomographic (CT anatomy of canine lumbosacral paraspinal muscles, a method for measuring paraspinal muscle transverse area ratios and asymmetry using CT, and application of this method in a small sample of working dogs with versus without lumbosacral pain.Methods: Published anatomy references and atlases were reviewed and discrepancies resolved by examination of anatomic specimens and multi-planar reformatted images to describe transverse CT anatomy of lumbosacral region paraspinal muscles. Sixteen Belgian malinois military working dogs were retrospectively recruited and assigned to lumbosacral pain positive versus negative groups based on medical record entries. A single observer unaware of dog group measured CT transverse areas of paraspinal muscles and adjacent vertebral bodies, in triplicate, for L5-S1 vertebral locations. A statistician compared muscle transverse area ratios and asymmetry at each vertebral location between groups. Results: The relative co-efficient of variation for triplicate CT area measurements averaged 2.15% (N=16. Multifidus lumborum (L6-7, psoas/iliopsoas (L5-6, L6-7, and sacrocaudalis dorsalis lateralis (L6-7, L7-S1 transverse area ratios were significantly smaller in dogs with lumbosacral pain (n=11 vs. without lumbosacral pain (n=5 (p< 0.05. Muscle asymmetry values were not significantly greater in dogs with vs. without lumbosacral pain. Clinical relevance: Computed tomographic morphometry of lumbosacral region paraspinal muscles is a feasible objective method for use in future evidence-based research studies in working dogs. Potential future research applications include determining whether decreased paraspinal muscle area ratios and/or increased paraspinal muscle asymmetry could be used as markers for preclinical lumbosacral pain in stoic dogs or risk factors for other injuries in high performance canine athletes; or determining whether core muscle strengthening exercise prescriptions

    In the Araripe region, Northeast Brazil, exist the world's second largest reserve of gypsum, estimated at over than one billion tons, which accounts for 95% of the Brazilian production and constitutes an important segment of the regional economy. The gypsum deposit occurs in the Lower Cretaceous Santana Formation of the Araripe basin, which is constituted by siltstones, marls, limestones, shales and gypsum layers. The ore extraction is from an open pit, on simple benches with a height of about 15 meters. Activities in mining operations involve stripping, drilling, loading explosives, blast, fragmentation and block loading / transport. Currently, gypsum mining and processing results in major changes in the landscape (pits and wastes heaps sedimentary rocks and soil mixture), deforestation of the "caatinga" ecosystem for use as firewood in small calcinations, dust pollution and changes in hydrology. To promote environmental remediation of this area, a multidisciplinary research has being done with the aim to support reforestation at the wastes heaps. The study involved the following activities: collection and physical, chemical and mineralogical characterization of mine waste materials; a floristic survey around the mines (botanical identification and measuring physical parameters in 16 plots, in order to identify which species are best suited to the conditions of the substrate at the mine site); an experiment (randomized block design) developed in a greenhouse, where seedlings of various native tree species were grown in a "constructed soil" made up of gypsum waste combined with chicken, goat and cattle manure, aimed to select tree species and soil treatment to be used in a waste heap; and an assessment of water quality for irrigation of the reforestation areas. The waste materials consist of large clayey aggregates, which may present physical/chemical properties unfavorable for plant development.

    The Green River-Moab area encompasses about 7800 square kilometers or about 25% of the Paradox basin. The entire Paradox basin is a part of the Colorado Plateaus that is underlain by a thick sequence of evaporite (salt) beds of Pennsylvanian age. The rock units that underlie the area have been grouped into hydrogeologic units based on their water-transmitting ability. Confining beds consist of evaporite beds of mostly salt, and overlying and underlying thick sequences of rocks with minimal permeability; above and below these confining beds are aquifers. The upper Mesozoic sandstone aquifer, probably is the most permeable hydrogeologic unit of the area and is the subject of this investigation. The principal component of groundwater outflow from this aquifer probably is subsurface flow to regional streams (the Green and Colorado Rivers) and is about 100 million cubic meters per year. All other components of outflow are relatively small. The average annual recharge to the aquifer is about 130 million cubic meters, of which about 20 million cubic meters is from local precipitation. For the lower aquifer, all recharge and discharge probably is by subsurface flow and was not estimated. The aquifers are generally isolated from the evaporite beds by the bounding confining beds; as a result, most ground water has little if any contact with the evaporites. Brines are present in the confining beds, but solution of beds of salt probably is very slow in most parts of the area. No brine discharges have been identified

    Steady-state regional groundwater flow of the Whiteshell Research Area (WRA) has been simulated in order to evaluate alternate locations for a hypothetical nuclear fuel waste disposal vault that maximize the retention of vault contaminants in long, slow groundwater flow paths through the geosphere. A revised conceptual model of the hydrogeologic conditions was constructed using all the information obtained from field investigations at the WRA between 1977 and 1994. All the simulations were performed using AECL's three-dimensional finite element code, MOTIF. A base-case simulation was performed using average value estimates of hydraulic parameters obtained from the field data, and freshwater was assumed to occur in the entire groundwater flow region. The simulated freshwater heads did not compare favourably with the freshwater beads that were derived from the field data. The simulated equivalent freshwater heads for the final calibrated model compared reasonably well with measured heads in the network of boreholes at the WRA. The simulated recharge rate for the final model was 4.8 mm/a Most of the groundwater flow in the model occurred in local systems between ground surface and a depth of 1000 m. A particle tracking code, TRACK3D, was used to determine the pathways, travel times and exit locations of particles released from different depths in the groundwater velocity field of the calibrated model. The exit locations of these pathways were found to be controlled by the network of regional fracture zones in the model. These results were used to select a location for a hypothetical nuclear fuel waste disposal vault in the regional groundwater flow model that maximizes the retention of vault contaminants in long, slow groundwater flow paths. A smaller region of about 75 km 2 was identified around this location for the development of a local geosphere model. (author). 32 refs., 4 tabs., 29 figs

    The Newmarket Till forms a regionally extensive aquitard separating two major aquifer systems in the Greater Toronto area, Canada. The till is incised, and sometimes eroded entirely, by a network of sand- and gravel-filled channels forming productive aquifers and, locally, high-conductivity windows between aquifer systems. Leakage through the till may also be substantial in places. This study investigates the spatial variability of aquitard leakance in order to assess the relative importance of recharge processes to the lower aquifers. With a large database derived from water-well records and containing both hard and soft information, the Sequential Indicator Simulation method is used to generate maps of aquitard thickness and window probability. These can be used for targeting channel aquifers and for identifying potential areas of recharge to the lower aquifers. Conductivities are modeled from sparse data assuming that their correlation range is much smaller than the grid spacing. Block-scale leakances are obtained by upscaling nodal values based on simulated conductivity and thickness fields. Under the "aquifer-flow'' assumption, upscaling is performed by arithmetic spatial averaging. Histograms and maps of upscaled leakances show that heterogeneities associated with aquitard windows have the largest effect on regional groundwater flow patterns. Résumé. La moraine glaciaire de Newmarket constitue un imperméable d'extension régionale séparant deux systèmes aquifères dans la région du Grand Toronto (Canada). La moraine est entaillée, et parfois entièrement érodée, par un réseau de chenaux comblés de sables et de graviers formant des aquifères productifs et, localement, des «fenêtres», zones à forte conductivité hydraulique reliant les systèmes aquifères. Une drainance au travers de la moraine peut également être significative par endroits. Cette étude s'intéresse à la variabilité spatiale de la drainance au travers de l

  17. A regional synergy approach to energy recovery: The case of the Kwinana industrial area, Western Australia

    International Nuclear Information System (INIS)

    Beers, D. van; Biswas, W.K.

    2008-01-01

    Energy is a key issue in the Kwinana industrial area, Western Australia's major heavy industrial region, where the major energy consuming industries consume upto 80 PJ/yr of energy in their processes. Over the past decade, significant progress has been made towards the reduction of energy consumption and reduction of greenhouse gases in Kwinana. One way to further advance sustainable energy use is through the realisation of regional synergies. These concern the capture, recovery and reuse of by-products, water and energy between industries in close proximity. Kwinana is recognised as a leading edge example in regional synergy development, but more synergy opportunities appear to exist. The centre for sustainable resource processing (CSRP) is undertaking research to develop new synergies in Kwinana, including energy utility synergies. As part of the research, a methodology was developed and applied to identify and evaluate the economic, technical, and environmental feasibility of collaborative energy recovery opportunities from industry flue gases in Kwinana. The trial application demonstrated the significant potential to mitigate CO 2 emissions through energy recovery from flue gases by applying technologies to convert the embedded energy into useful thermal and electric applications. This article discusses the methodology and outcomes from the trial applications, including the impact of carbon taxes, reducing costs of emerging technologies, and increasing energy prices

  18. Rostro-Caudal Organization of Connectivity between Cingulate Motor Areas and Lateral Frontal Regions

    2018-01-01

    Full Text Available According to contemporary views, the lateral frontal cortex is organized along a rostro-caudal functional axis with increasingly complex cognitive/behavioral control implemented rostrally, and increasingly detailed motor control implemented caudally. Whether the medial frontal cortex follows the same organization remains to be elucidated. To address this issue, the functional connectivity of the 3 cingulate motor areas (CMAs in the human brain with the lateral frontal cortex was investigated. First, the CMAs and their representations of hand, tongue, and eye movements were mapped via task-related functional magnetic resonance imaging (fMRI. Second, using resting-state fMRI, their functional connectivity with lateral prefrontal and lateral motor cortical regions of interest (ROIs were examined. Importantly, the above analyses were conducted at the single-subject level to account for variability in individual cingulate morphology. The results demonstrated a rostro-caudal functional organization of the CMAs in the human brain that parallels that in the lateral frontal cortex: the rostral CMA has stronger functional connectivity with prefrontal regions and weaker connectivity with motor regions; conversely, the more caudal CMAs have weaker prefrontal and stronger motor connectivity. Connectivity patterns of the hand, tongue and eye representations within the CMAs are consistent with that of their parent CMAs. The parallel rostral-to-caudal functional organization observed in the medial and lateral frontal cortex could likely contribute to different hierarchies of cognitive-motor control.

    Head and neck cancer treatment affects quality of life. There are differences in quality of life outcomes and perceived supportive care needs between cancer patients living in metropolitan and regional-remote areas. This study investigated quality of life over the first 6 months following head and neck cancer diagnosis and observed differences in quality of life by geographical location. Prospective observational study. Tertiary hospital in Brisbane, Australia. Newly diagnosed patients who were referred for the diagnosis, and/or treatment of head and neck cancer. Quality of life was measured by the University of Washington Quality of Life Survey, version 4 (UW-QoL). Participants completed the UW-QoL questionnaire prior to starting treatment, 1 month and 6 months post treatment. Metropolitan and regional or remote status was classified according to the Australian Standard Geographic Classification-Remoteness Area system. Ninety-five participants were included at baseline; 49 and 41 participants completed the 1-month and 6-month follow-ups, respectively. Scores in most UW-QoL domains decreased between baseline and 1 month post treatment and increased towards pre-treatment scores at the 6-month follow-up (except for anxiety and saliva). Pain at baseline was significantly worse in the regional-remote participants compared with metropolitan participants. No other statistically significant differences in UW-QoL score by geographical location were observed. The findings generally did not support significant differences in quality of life outcome between metropolitan and regional-remote head and neck cancer patients. The difference in pain experience between metropolitan and regional-remote groups requires further investigation. © 2018 National Rural Health Alliance Ltd.

    AECL is investigating a concept for disposing of nuclear fuel waste deep in plutonic rock of the Canadian Shield. As part of this investigation, we have performed a model simulation of regional groundwater flow in the Atikokan Research Area, a fractured plutonic rock environment of the Canadian Shield, and used the distribution of oxygen-18 ( 18 O) and tritium ( 3 H) in groundwater to test the model. At the first stage of model calibration, groundwater flow was simulated using a three-dimensional finite-element code, MOTIF, in conjunction with a conceptual framework model derived from field geological, geophysical and hydrogeological data. Hydraulic parameters (permeability and porosity) were systematically varied until simulated recharge rates to the water table compared favourably with estimated recharge rates based on stream flow analysis. At the second stage, vertical average linear groundwater velocities from the first stage of the calibration process were combined with conceptualized one-dimensional models of the system to generate depth concentration profiles of 18 O and 3 H. Recharge-, midline-and discharge area models of both the fracture zones and the rock mass were employed. The simulated profiles formed 'envelopes' around all field 18 O and 3 H data, indicating that the calibrated velocities used in the model are reasonable. The models demonstrate that the scatter of δ 18 O and 3 H field data from the Atikokan Research Area is consistent with the groundwater flow model predictions and can be explained by the complexity arising from different hydraulic regimes (recharge, midline, discharge) and hydrogeologic environments (fracture zones, rock mass) of the regional flow system. 50 refs., 14 figs., 3 tabs

  1. An Analysis of Rural Household Livelihood Change and the Regional Effect in a Western Impoverished Mountainous Area of China

    2018-05-01

    Full Text Available Taking Longnan, in the western Qinling Mountains region of Gansu province, China, as our study area, and using the Sixth National Population Census alongside household survey data, we analyze changes in household livelihoods, and consequent regional effects, following the instigation of the “Grain for Green” program in 1999. Our results show rural livelihood changes with respect to natural assets (e.g., reduction of arable land, planting structure changes, human assets (e.g., labor quality improvement, fluidity of population, financial assets (e.g., income channels widening, income increasing, physical assets (e.g., optimized production tools, and social assets (e.g., information network development, increased outreach opportunities. We suggest that increased household livelihoods play an important role in improving land space utilization efficiency, resource conservation and use, and the ecological environment. However, owing to the natural environment, there are also some problems, such as “hollows” in rural production and living spaces, as well as local environmental degradation. To address these issues, regions such as the western, mountainous, impoverished area of our study should establish a policy of using ecosystems, as well as agriculture, for development in order to improve household livelihoods, build an efficient spatial structure, and providing support for the creation of a resource-saving societal system.

    The study area, an activation zone of the median Massif in Xingmeng geosynclinal area, geologically underwent the multiple tectono-magmatic reworking of granitizations during Shinagan, Caledonia and Hercynian periods and of continental rift volcanism in the Mesozoic-Cenozoic era. It is an important potential area for uranium metallogenesis in volcanic basin in North China. The study identifies that four stages of uranium preconcentration and three phases of hydrothermal superimposed-reworking uranium metallogenesis occurred along with the regional geological elevation process. Studies on the U-Pb isotope and induced fission track of various kinds of basement rocks from the area indicate that the basement composed of crustal source remelting type Caledonian and Hercynian granites is favourable for uranium metallogenesis in volcanic basin, and that the late Jurassic intermediate-acid volcano-rock directly act as the source of uranium and that Cretaceous-Tertiary extension-rift basalt magmatic activation supply an important hydrothermal reworking condition for the uranium metallogenesis in volcanic basin. Based on comparative study on the metallogenetic conditions of typical large-scale volcanic uranium deposits at home and abroad, nine prospecting criteria are summarized, the polygenetic mixing hydrothermal uranium metallogenetic model for penetrable volcano-collapse basin is presented, and the main prospecting targets of uranium deposits are pointed out.

    Full Text Available This paper presents the history of occupation in the water source areas in São Paulo Metropolitan Region (hereinafter SPMR and the evolution of the legislation related to this issue, from the point of view of the environmental and water management. A descriptive methodology was used, with searches into bibliographical and documental materials, in order to present the main laws for the protection of the water supply areas of SPMR and environmental and water management. It was possible to observe some progress in the premises of the both legislation and the format proposed for the management of the water source areas. However, such progress is limited due to the lack of a more effective mechanism for metropolitan management. The construction of the metropolitan management in SPMR would enlarge the capacity of integration between municipalities and sectors. The integration between the management of water and the land use management showed to be fundamental for the protection of the water sources. The new law for protection of the water sources, State Law nº 9.866/97, is decentralized and participative, focusing on non-structural actions and integrated management. However, the effective implementation of the law still depends on the harmonization of sectoral public policies, extensive coordination and cooperation among municipalities and the progress in the degree of the commitment of the governments.

    The case study presents the use of statistical methods and analysis tools, for hazard assessment of "urbanization units", implemented in a Geographic Information Systems (GIS) environment. As a case study, the Levoča region (Slovakia) is selected. The region, with a total area of about 351 km2, is widely affected by landslides and floods. The problem, for small urbanization areas, is nowadays particularly significant from the socio-economic point of view. It is considered, presently, also an increasing problem, mainly because of climate change and more frequent extreme rainfall events. The geo-hazards are evaluated using a multivariate analysis. The landslide hazard assessment is based on the comparison and subsequent statistical elaboration of territorial dependence among different input factors influencing the instability of the slopes. Particularly, five factors influencing slope stability are evaluated, i.e. lithology, slope aspect, slope angle, hypsographic level and present land use. As a result a new landslide susceptibility map is compiled and different zones of stable, dormant and non-stable areas are defined. For flood hazard map a detailed digital elevation model is created. A compose index of flood hazard is derived from topography, land cover and pedology related data. To estimate flood discharge, time series of stream flow and precipitation measurements are used. The assessment results are prognostic maps of landslide hazard and flood hazard, which presents the optimal base for urbanization planning.

    Many regions of Earth have glaciers that have been neglected for study because they are small. We report on a new approach to overcome the problem of studying small glaciers, using Turkey as an example. Prior to our study, no reliable estimates of Turkish glaciers existed because of a lack of systematic mapping, difficulty in using Landsat data collected before 1982, snowpack vs. glacier ice differentiation using existing satellite data and aerial photography, the previous high cost of Landsat images, and a lack of high-resolution imagery of small Turkish glaciers. Since 2008, a large number of area of nine smaller glaciers in Turkey. We also used five Landsat-3 Return Beam Videcon (RBV) 30 m pixel resolution images, all from 1980, for six glaciers. The total area of Turkish glaciers decreased from 23 km2 in the 1970s to 10.1 km2 in 2007-2011. By 2007-2011, six Turkish glaciers disappeared, four were < 0.3 km2, and only three were 1.0 km2 or larger. No trends in precipitation from 1970 to 2006 and cloud cover from 1980 to 2010 were found, while surface temperatures increased, with summer minimum temperatures showing the greatest increase. We conclude that increased surface temperatures during the summer were responsible for the 56% recession of Turkish glaciers from the 1970s to 2006-2011.

    The remote sensing images and geological features of Beishan area indicate that the Altyn Tagh fault, Sanweishan-Shuangta fault, Daquan fault and Hongliuhe fault are distributed in Beishan area from south to north. The faults are all left-lateral strike-slip faults with trending of NE40-50°, displaying similar distribution pattern. The secondary branch faults are developed at the end of each main strike-slip fault with nearly east to west trending form dendritic oblique crossings at the angle of 30-50°. Because of the left-lateral slip of the branch faults, the granites or the blocks exposed within the branch faults rotate clockwisely, forming 'Domino' structures. So the structural style of Beishan area consists of the Altyn Tagh fault, Sanweishan-Shuangta fault, Daquan fault, Hongliuhe fault and their branch faults and rotational structures between different faults. Sedimentary analysis on the fault valleys in the study area and ESR chronological test of fault clay exhibit that the Sanweishan-Shuangta fault form in the late Pliocene (N2), while the Daquan fault displays formation age of l.5-1.2 Ma, and the activity age of the relevant branch faults is Late Pleistocene (400 ka). The ages become younger from the Altyn Tagh fault to the Daquan fault and strike-slip faults display NW trending extension, further revealing the lateral growth process of the strike-slip boundary at the northern margin during the Cenozoic uplift of Tibetan Plateau. The displacement amounts on several secondary faults caused by the activities of the faults are slight due to the above-mentioned structural distribution characteristics of Beishan area, which means that this area is the most stable active area with few seismic activities. We propose the main granitic bodies in Beishan area could be favorable preselected locations for China's high level radioactive waste repository. (authors)

    Meleux, F.; Rosset, R.

    On June and July 2001, the campaign ESCOMPTE took place in the Marseille area in southern of France, with the aim of generating a detailed 3-D data base for the study of dynamics and chemistry of high pollution events so as to validate and improve air quality models. Previous to this field experiment, a pre-modelling exercise has been performed to document the dynamic interactions between sea and land breezes and orographics flows over this complex topographical area. This study was carried out using a nesting procedure at local and regional scales using the MESO-NH model (jointly developed by Laboratoire d'Aérologie and Meteofrance at Toulouse). Tracers emitted at various locations in the Marseille and Etang de Berre areas were first fol- lowed, then in a second step, full chemistry simulations have been run for two selected periods on June and July 1999, quite similar to the meteorological situations met dur- ing the IOP2a and the IOP4 in the 2001 campaign. The performance of the model has been assessed by comparing measured data with simulated data for meteorological pa- rameters and ozone. The general ability of the model to correctly simulate these two situations allows to further study ozone plume developments in more details. In par- ticular, these studies bear upon the relative roles of O3 transport versus O3 chemical production, as a function of distance within the plume to anthropogenic emissions and biogenic emissions, together with ozone daily variations and peak values observed at rural sites.

    Full Text Available The paper aims to present as an organic structure the outcomes from various pieces of research and consulting activities developed over the last few years (2011-2015. Shared topics are: urban-rural partnerships, food planning, metropolitan polices and the territorial resilience of periurban areas. In the first part (the core of the paper the paper underlines critical questions and establishes needs so as to move towards a new approach to development processes in periurban areas. The paper uses some key concepts to present the main outcomes: 1. Understanding complexity (multiscales in space and dynamics (multiscales in time; 2. Identifying all the resources and opportunities; 3. Crosscutting and multi-issues. In the second part (in the final part the paper proposes the “Ecotone” metaphor to support innovation in the approach to periurban areas. It is a “zone of transition between adjacent ecological systems, having a set of characteristics uniquely defined by space and time scales and by the strength of the interactions between adjacent ecological systems” (Hansen et al, 1992. In these terms, periurban areas may be assumed to be ecotonal zones of transition between urban and rural or natural systems. Using the concept of “ecotonal buffer of transition” to approach the periurban systems it is possible to connect main needs and critical questions underlined to a homogeneous framework and to emphasise on the strategic role that the peri-urban systems play for the future development of metropolitan regions oriented to a improvement of resilience of socio-ecosystems. In the final part the paper focuses on the governace of urban rural partnerships and research perspectives.

    Full Text Available This paper discusses the relative performance of several climate models in providing reliable forcing for hydrological modeling in six representative catchments in the Mediterranean region. We consider 14 Regional Climate Models (RCMs, from the EU-FP6 ENSEMBLES project, run for the A1B emission scenario on a common 0.22° (about 24 km rotated grid over Europe and the Mediterranean region. In the validation period (1951 to 2010 we consider daily precipitation and surface temperatures from the observed data fields (E-OBS data set, available from the ENSEMBLES project and the data providers in the ECA&D project. Our primary objective is to rank the 14 RCMs for each catchment and select the four best-performing ones to use as common forcing for hydrological models in the six Mediterranean basins considered in the EU-FP7 CLIMB project. Using a common suite of four RCMs for all studied catchments reduces the (epistemic uncertainty when evaluating trends and climate change impacts in the 21st century. We present and discuss the validation setting, as well as the obtained results and, in some detail, the difficulties we experienced when processing the data. In doing so we also provide useful information and advice for researchers not directly involved in climate modeling, but interested in the use of climate model outputs for hydrological modeling and, more generally, climate change impact studies in the Mediterranean region.

    The complex nature of cost analysis and systems work demands a level of effort to ensure that decisions made support the best interests of all parties. This tradeoff study will act as a formal decision analysis method for the evaluation of many variables. The documentation of the decision rationale and system design is essential for successful planning and implementation of any system. The Hanford Site offers unique problems for economic analysis of remediation alternatives. The variations in the size of sites, geographic locations, and possible cleanup scenarios all add to the complexity of the tradeoff analysis. A thorough examination of all alternatives must be held to a level of detail appropriate to current regulatory and budgetary considerations. This study will compare the economics of two specific alternatives for remediation of soils at the Hanford Site. Remove and dispose is compared to remove, treat, and dispose. The treatment analyzed in this study is volume reduction through soil washing

    This report documents a study conducted to develop a regional groundwater flow model for the Eastern Snake River Plain Aquifer in the area of the Idaho National Engineering Laboratory. The model was developed to support Waste Area Group 10, Operable Unit 10-04 groundwater flow and transport studies. The products of this study are this report and a set of computational tools designed to numerically model the regional groundwater flow in the Eastern Snake River Plain aquifer. The objective of developing the current model was to create a tool for defining the regional groundwater flow at the INEL. The model was developed to (a) support future transport modeling for WAG 10-04 by providing the regional groundwater flow information needed for the WAG 10-04 risk assessment, (b) define the regional groundwater flow setting for modeling groundwater contaminant transport at the scale of the individual WAGs, (c) provide a tool for improving the understanding of the groundwater flow system below the INEL, and (d) consolidate the existing regional groundwater modeling information into one usable model. The current model is appropriate for defining the regional flow setting for flow submodels as well as hypothesis testing to better understand the regional groundwater flow in the area of the INEL. The scale of the submodels must be chosen based on accuracy required for the study

    A number of cases of Loa encephalopathy have been recorded after ivermectin treatment in the Lekie Division, an area of degraded forest located in central Cameroon. An entomological study was carried out in a village of this region between May 1999 and April 2000 to determine whether the high microfilarial loads of Loa found in the population, which can exceed 10,000 microfilariae per ml of blood, were related to high densities of vector populations. The Chrysops collected at 10 catching stations, using hand nets, by persons standing by a wood fire, were dissected to evaluate their level of infection with Loa. The vectorial densities were three-fold higher in the forest stations than in those located near the habitations (2307 and 725 bites per man per year, respectively). These values are lower than those reported from similar studies in Cameroon, Congo and Gabon. Measurement of Chrysops densities does not seem to be an appropriate tool to evaluate the level of endemicity of loiasis, and to delineate the areas where there is a risk of post-ivermectin Loa encephalopathies.

    The karst region of Southwest China with an area of 54 × 104 km2 is one of the largest karst areas in the world and experiences subtropical climate. Hill-depressions are common landforms in the mountain areas of this region. Downslope soil movement on the ground by surface water erosion and soil sinking into underground holes by creeping or pipe erosion are mayor types of soil movements on rocky carbonate slopes. The 137Cs technique was used to date the sediment deposits in six karst depressions, to estimate average surface erosion rates on slopes from their catchments. The estimates of soil loss rates obtained from this study evidenced considerable variability. A value of 1.0 t km-2 year-1 was obtained for a catchment under original dense karst forest, but the erosion rates ranged between 19.3 t km-2 year-1 and 48.7 t km-2 year-1 in four catchments under secondary forest or grasses, where the original forest cover had been removed in the Ming and Qing dynasties, several hundred years ago. The highest rate of 1643 t km-2 year-1 was obtained for a catchment underlain by clayey carbonate rocks, where the soil cover was thicker and more extensive than in the other catchments and extensive land reclamation for cultivation had occurred during the period 1979-1981, immediately after the Cultural Revolution.

    Introduction: High level radiation areas have been recognized on various parts of the earth. Some of these areas include: Brasilia, India, and Iran. Mahallat hot spring region in the central part of Iran is also one of these areas. Study of exposure in these areas could be helpful in investigating the effects of ionizing radiation. Materials and Methods: In addition to several seasonal springs, Mahallat hot spring region contains five permanent springs named: Soleimani, Shafa, Dombe, Romatism and Sauda. Internal exposure (due to inhalation of radon gas and drinking water) and external exposure (due to cosmic rays and radioactive elements in the ground) to the tourists was studied. Used materials and apparatus include: RSS -112 ionizing chamber for environmental gamma rays exposure measurement, highly pure germanium detector for measuring radioactive elements in the ground, liquid scintillation counter for measuring 222 Rn gas concentration in water samples, Bubbler chamber and Locus cells for Rn concentration measurements (Emanation method) and Alfa guard detector for 226 Ra concentration measurements. Conclusions and Discussion: A total of 270 visitors are included in this study. Considering residual durations of the studied group in open and closed environment of bathrooms, hotel and inn rooms, obtained annual external effective dose is 75.4±8.7μSv and 138.3±11.8μSv for natives and travelers respectively. EEC coefficients has been used for calculating annual internal effective dose due to radon gas inhalation. Annual internal effective dose, in this path, is 0.9 and 2.1 mSv in open and closed environment for native and visitors respectively. Annual internal effective dose due to drinking water, is 0.43 and 0.09μSv for natives people and travelers, respectively. Measurements show that more than 90% of the received dose in the studied groups is due to radon gas inhalation. External and internal dose summation is 0.98 mSv for natives and 2.2 mSv for for

    The radioactive fallout after Chernobyl accident caused serious contamination by 137Cs along extensive area of East-European plain.Cs137 fall down on earth surface in two ways: gravitational - "dry" and rainfall - "wet" way. "Dry" fallout is a result of direct deposition of radionuclides from atmosphere with average speed of about 0.1-1 mm/sec. The fate of "dry fall"is far less than rainfall mechanism. Erupted water steam of reactor zone full of radioactive material enriched precipitation with 137Cs. Therefore, the derived spatial structure of contamination was under control of rainfall pattern in May-June 1986. On the areas affected by rainfall fallout was the Southern part of Tula region in Middle Russia. It got name as "Plava hot spot" by the town in the center of this area. Tula is a traditional rural region, the vast areas covered by chernozem soils are cultivated for centuries. During cultivation forest cover was reduced that urged growth of wind erosion and loss of soil fertility. Hence, in the middle of 20 the century large arrangements for creation of forest shelterbelts were conducted. High efficiency of shelterbelts made them a widely provided part of new human-transformed landscape. Usually shelterbelts are set as a regular network across main direction of winds in particular region. Such organization help to reduce speed of air steam in the lowest 20-30 m layer of atmosphere. In addition, shelterbelts are very good collectors of snow in winter time which increase total moisture of soil and its fertility. Represented investigation is conducted to find out any correlation between shelterbelts and fallout of radionuclides. If such correlation is significant, it has to be taken into account for further environmental surveys. Two shelterbelts on the interfluve positions were chosen for detailed examination. Both selected objects emerged before 1986 but have different width, floristic composition, orientation and type of construction. One of shelterbelts is

    To identify the species of Leishmania present in the skin lesions of patients and Lutzomyias living in endemic areas of La Libertad, Peru. Molecular methods based on PCR and RFLP were used, which allowed to have efficient data with small amounts of samples (small specimens), due to their high sensitivity and ease of application in the field work. The results of PCR of clinical samples of patients and insect vectors showed the presence of Leishmania (V.) peruviana as a major causative agent of andean leishmaniasis transmitted by Lutzomyia peruensis. The presence of Leishmania (V.) guyanensis in Lutzomyia ayacuchensis, was found as well. The presence of L. (V.) peruviana and L. (V.) guyanensis in the Andean areas under study was found. These findings remark the need of a wider research about the geographical distribution of L. (V.) guyanensis and clinical features related to the infection in endemic areas of cutaneous leishmaniasis.

    Urbanization is one of the major environmental challenges facing the world today. One of its particularly pressing effects is alterations to local and regional climate through, for example, the Urban Heat Island. Such changes in conditions are likely to have an impact on the phenology of urban vegetation, which will have knock-on implications for the role that urban green infrastructure can play in delivering multiple ecosystem services. Here, in a human-dominated region, we undertake an explicit comparison of vegetation phenology between urban and rural zones. Using satellite-derived MODIS-EVI data from the first decade of the 20th century, we extract metrics of vegetation phenology (date of start of growing season, date of end of growing season, and length of season) for Britain's 15 largest cities and their rural surrounds. On average, urban areas experienced a growing season 8.8 days longer than surrounding rural zones. As would be expected, there was a significant decline in growing season length with latitude (by 3.4 and 2.4 days/degree latitude in rural and urban areas respectively). Although there is considerable variability in how phenology in urban and rural areas differs across our study cities, we found no evidence that built urban form influences the start, end, or length of the growing season. However, the difference in the length of the growing season between rural and urban areas was significantly negatively associated with the mean disposable household income for a city. Vegetation in urban areas deliver many ecosystem services such as temperature mitigation, pollution removal, carbon uptake and storage, the provision of amenity value for humans and habitat for biodiversity. Given the rapid pace of urbanization and ongoing climate change, understanding how vegetation phenology will alter in the future is important if we wish to be able to manage urban greenspaces effectively.

    The gravity and magnetic maps of the area between Adana-Kahramanmaras-Hatay provinces were produced from a compilation of data gathered during the period between 1973 and 1989. Reduced to the pole (RTP) and pseudo-gravity transformation (PGT) methods were applied to the magnetic data, while derivative ratio (DR) processing was applied to both gravity and magnetic data, respectively. Bouguer, RTP and PGT maps show the image of a buried structure corresponding to ophiolites under undifferentiated Quaternary deposits in the Adana depression and Iskenderun Gulf. DR maps show two important faults which reflect the tectonic framework in the study area: (1) the Karatas-Osmaniye Fault extending from Osmaniye to Karatas in the south between Adana and Iskenderun depressions and (2) Amanos Fault (southern part of East Anatolian Fault) in the Hatay region running southward from Turkoglu to Amik Basin along Amanos Mountain forming the actual plate boundary between the Anatolian block (part of Eurasian plate) and Arabian plate.

    In nuclear preparedness, an essential requirement is the ability to adequately predict the likely consequences of a major accident situation. In this context it is very important to evaluate which contributions to dose are important, and which are not likely to have significance. As an example of this type of evaluation, a case study has been conducted to estimate the doses received over the first 17 years after the Chernobyl accident in a dry-contaminated residential area in the Bryansk region in Russia. Methodologies for estimation of doses received through nine different pathways, including contamination of streets, roofs, exterior walls, and landscape, are established, and best estimates are given for each of the dose contributions. Generally, contaminated soil areas were estimated to have given the highest dose contribution, but a number of other contributions to dose, e.g., from contaminated roofs and inhalation of contaminants during the passage of the contaminated plume, were of the same order of magnitude

    Full Text Available Postharvest loss is one major problem farmers in Adaklu Traditional Area that most Ghanaian farmers face. As a result, many farmers wallow in abject poverty. Warehouses are important facilities that help to reduce postharvest loss. In this research, Beresnev pseudo-Boolean Simple Plant Location Problem (SPLP model is used to locate a warehouse at Adaklu Traditional Area, Volta Region, Ghana. This model was used because it gives a straightforward computation and produces no iteration as compared with other models. The SPLP is a problem of selecting a site from candidate sites to locate a plant so that customers can be supplied from the plant at a minimum cost. The model is made up of fixed cost and transportation cost. Location index ordering matrix was developed from the transportation cost matrix and we used it with the fixed cost and differences between variable costs to formulate the Beresnev function. Linear term developed from the function which was partial is pegged to obtain a complete solution. Of the 14 notable communities considered, Adaklu Waya is found most suitable for the setting of the warehouse. The total cost involved is Gh₵ 78,180.00.

    Various classification methods have been applied for low resolution of the entire Earth's surface from recorded satellite images, but insufficient study has determined which method, for which satellite data, is economically viable for tropical forest land use mapping. This study employed Iterative Self Organizing Data Analysis Techniques (ISODATA) and K-Means classification techniques to classified Moderate Resolution Imaging Spectroradiometer (MODIS) Surface Reflectance satellite image into forests, oil palm groves, rubber plantations, mixed horticulture, mixed oil palm and rubber and mixed forest and rubber. Even though frequent cloud cover has been a challenge for mapping tropical forests, our MODIS land use classification map found that 2008 ISODATA-1 performed well with overall accuracy of 94%, with the highest Producer's Accuracy of Forest with 86%, and were consistent with MODIS Land Cover 2008 (MOD12Q1), respectively. The MODIS land use classification was able to distinguish young oil palm groves from open areas, rubber and mature oil palm plantations, on the Advanced Land Observing Satellite (ALOS) map, whereas rubber was more easily distinguished from an open area than from mixed rubber and forest. This study provides insight on the potential for integrating regional databases and temporal MODIS data, in order to map land use in tropical forest regions.

    The State of Mato Grosso - MT has the second largest area with degraded forest among the states of the Brazilian Legal Amazon. Land use and land cover change processes that occur in this region cause the loss of forest biomass, releasing greenhouse gases that contribute to the increase of temperature on earth. These degraded forest areas lose biomass according to the intensity and magnitude of the degradation type. The estimate of forest biomass, commonly performed by forest inventory through sample plots, shows high variance in degraded forest areas. Due to this variance and complexity of tropical forests, the aim of this work was to estimate forest biomass using LiDAR point clouds in three distinct forest areas: one degraded by fire, another by selective logging and one area of intact forest. The approach applied in these areas was the Individual Tree Detection (ITD). To isolate the trees, we generated Canopy Height Models (CHM) images, which are obtained by subtracting the Digital Elevation Model (MDE) and the Digital Terrain Model (MDT), created by the cloud of LiDAR points. The trees in the CHM images are isolated by an algorithm provided by the Quantitative Ecology research group at the School of Forestry at Northern Arizona University (SILVA, 2015). With these points, metrics were calculated for some areas, which were used in the model of biomass estimation. The methodology used in this work was expected to reduce the error in biomass estimate in the study area. The cloud points of the most representative trees were analyzed, and thus field data was correlated with the individual trees found by the proposed algorithm. In a pilot study, the proposed methodology was applied generating the individual tree metrics: total height and area of the crown. When correlating 339 isolated trees, an unsatisfactory R² was obtained, as heights found by the algorithm were lower than those obtained in the field, with an average difference of 2.43 m. This shows that the

    Full Text Available Abstract Background The possibility for commercial mining of deep-sea manganese nodules is currently under exploration in the abyssal Clarion-Clipperton Fracture Zone. Nematodes have potential for biomonitoring of the impact of commercial activity but the natural biodiversity is unknown. We investigate the feasibility of nematodes as biomonitoring organisms and give information about their natural biodiversity. Results The taxonomic composition (at family to genus level of the nematode fauna in the abyssal Pacific is similar, but not identical to, the North Atlantic. Given the immature state of marine nematode taxonomy, it is not possible to comment on the commonality or otherwise of species between oceans. The between basin differences do not appear to be directly linked to current ecological factors. The abyssal Pacific region (including the Fracture Zone could be divided into two biodiversity subregions that conform to variations in the linked factors of flux to the benthos and of sedimentary characteristics. Richer biodiversity is associated with areas of known phytodetritus input and higher organic-carbon flux. Despite high reported sample diversity, estimated regional diversity is less than 400 species. Conclusion The estimated regional diversity of the CCFZ is a tractable figure for biomonitoring of commercial activities in this region using marine nematodes, despite the immature taxonomy (i.e. most marine species have not been described of the group. However, nematode ecology is in dire need of further study.

    Agricultural terraces represent the territorial structure of many cultural landscapes in the Campania region, Italy. Historic urban/rural settlements and hydraulic-agrarian systems have been developed on mountains and hills, producing diverse cultural landscapes depending on the specific geological, pedological and geomorphological characteristics, which influenced the character and functions of terraces. These unique landscapes are multi-functional and provide many ecosystem services: provisioning (food, water retention, building materials); regulating and maintenance (hydrogeological stability, soil fertility, protection from soil erosion, maintenance of genetic diversity, habitat); cultural services (heritage and traditional knowledge conservation, tourism and recreation, spiritual experience, education, aesthetic quality). Three terraced landscapes in Campania are analysed, which present a rich diversity in the geological structure and formal/functional characteristics: the Roccamonfina vulcanic area, a highly fertile and lapillous soil; the Monte di Bulgheria, a clay-rich area; and finally the well-known UNESCO World Heritage site of the Amalfi Coast, a calcareous, steep rock faced area. A landscape character assessment of the three sites is processed, identifying the biophysical structure of the sites, natural systems and land use, and cultural and anthropic elements. Terraced landscapes in Campania can be regenerated, taking again an active social and economic role for the society, enhancing their multifunctionality as a key source of wellbeing. Ecosystem services are mapped and evaluated to assess benefits and costs in a multidimensional framework. Spatial analysis in GIS environment supports this process, providing a decision-support tool for mapping and assessment of terraced landscapes, to convert their actual and potential value into a resource of economic sustainable development.

    Persistent monitoring of progress, evaluating the results of interventions and recalibrating to achieve continuous improvement over time is widely recognized as being crucial towards the successful development of road safety. In the ASEAN (Association of Southeast Asian Nations) region there is a lack of well-resourced teams that contain multidisciplinary safety professionals, and specialists in individual countries, who are able to carry out this work effectively. In this context, not only must the monitoring framework be effective, it must also be easy to use and adapt. This paper provides a case study that can be easily reproduced; based on an updated and refined Road Safety Development Index (RSDI), by means of the RSR (Rank-sum ratio)-based model, for monitoring/reporting road safety development at regional level. The case study was focused on the road safety achievements in eleven Southeast Asian countries; identifying the areas of poor performance, potential problems and delays. These countries are finally grouped into several classes based on an overview of their progress and achievements regarding to road safety. The results allow the policymakers to better understand their own road safety progress toward their desired impact; more importantly, these results enable necessary interventions to be made in a quick and timely manner. Keeping action plans on schedule if things are not progressing as desired. This would avoid 'reinventing the wheel' and trial and error approaches to road safety, making the implementation of action plans more effective. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The mountainous area of Beijing is the broad region with weak economic features, ecologically fragile and special ecological functions. The ecological conditions, sustainability and regional economic development are intercorrelated in the region. It is arduous to enhance the regional competitive advantage and improve the economic development level through the environmental protection and ecological conservation. This study elaborates the relationship between ecology and economic development from the perspectives of ecology, productivity and life style in mountainous areas of Beijing. Then this paper discusses how to increase sustainable development of mountain areas from several aspects, including key regional developments, industrial development, and ecological compensation mechanism, considering the strategic goals of accelerating economic transformation, coordinating urban and rural development, and promoting new-type urbanization.

    This study aims at hydrological model verification of a small lowland interfluve area (18.6 km²) in NE Belgium, for conditions that are different than today. We compare the current state with five reference periods in the past (AD 1500, 1770, 1854, 1909 and 1961) representing important stages of landscape evolution in the study area. Historical information and proxy data are used to derive conceptual model features and boundary conditions specific to each period: topography, surface water geometry (canal, drains and lakes), land use, soils, vegetation and climate. The influence of landscape evolution on the hydrological cycle is assessed using numerical simulations of a coupled unsaturated zone - groundwater model (HYDRUS-MODFLOW). The induced hydrological changes are assessed in terms of groundwater level, recharge, evapotranspiration, and surface water discharge. HYDRUS-MODFLOW coupling allows including important processes such as the groundwater contribution to evapotranspiration. Major land use change occurred between AD 1854 and 1909, with about 41% of the study area being converted from heath to coniferous forest, together with the development of a drainage network. Results show that this led to a significant decrease of groundwater recharge and lowering of the groundwater table. A limitation of the study lies in the comparison of simulated past hydrology with appropriate palaeo-records. Examples are given as how some indicators (groundwater head, swamp zones) can be used to tend to model validation. Quantifying the relative impact of land use and climate changes requires running sensitivity simulations where the models using alternative land use are run with the climate forcing of other periods. A few examples of such sensitivity runs are presented in order to compare the influence of land use and climate change on the study area hydrology.

    For the purpose of estimating the radiological health and safety to the Egyptian population arises from the natural background involved with coastal areas, it is necessary to make a comprehensive study to investigate the natural radionuclides activities in this environmental ecology. The locations of such areas were chosen from those in which people spend some time (e.g. the Mediterranean and Red Sea beaches, Suez Canal in addition to the River Nile Ismailia Canal and Quaroun Lake). Water and soil samples were brought from these locations and subjected to intensive physical, chemical analysis and radiological investigations. The densities of the collected soil samples were found to fall in the region of clay densities (2.30 - 2.70 g/cm 3 ). The particle size distribution analysis, of these soil samples showed values ranging from 128 Μ m to 1303 Μ according to sample site. The collected samples are mainly silicates with variable amounts of the major cations; Ca + +, Mg + +, Na + , K + with some other trace elements. For the radiological investigations 238 U , 226 R a, 232 T h and 40 K activity concentrations were resolved by spectroscopy technique. The majority of samples examined in this work showed variable activities of the naturally occurring radionuclides with fairly low levels compared with literature values reported in other countries. The analysis and discussions of the obtained data are thoroughly performed with the use of equations to estimate the radiation doses

    Full Text Available An interprovincial boundary region is a new subject of economic disparity study in China. This study explored the multi-scale spatio-temporal dynamics of economic development from 1995 to 2010 in the interprovincial boundary region of Sichuan-Yunnan-Guizhou, a mountain area and also the junction area of Tibetan Plateau, Hengduan Mountain, Yungui Plateau and Sichuan Basin in southwestern China. A quantitative study on county GDP per capita for different scales of administrative regions was conducted using the Theil index, Markov chains, a geographic information system and exploratory spatial data analysis. Results indicated that the economic disparity was closely related with geographical unit scale in the study area: the smaller the unit, the bigger the disparity, and the regional inequality gradually weakened over time. Moreover, significant positive spatial autocorrelation and clustering of economic development were also found. The spatial pattern of economic development presented approximate circle structure with two cores in the southwest and northeast. The Panxi region in the southwest core and a part of Hilly Sichuan Basin in the northeast core were considered to be hot spots of economic development. Most areas in the east and central region were persistently trapped in the low level of a balanced development state, with a poverty trap being formed in the central and south part. Geographical conditions and location, administrative barriers and the lack of effective growth poles may be the main reasons for the entire low level of balanced development. Our findings suggest that in order to achieve a high level of balanced development, attention should be paid beyond developing transportation and other infrastructure. Breaking down the rigid shackles of administrative districts that hinder trans-provincial cooperation and promoting new regional poles in the Yunnan-Guizhou region may have great significance for the study area.

    Full Text Available The goal. The analyses of radiation hygienic monitoring conducted in Tula region territories affected by the Chernobyl NPP accident regarding cesium-137 and strontium- 90 in the local foodstuffs and the analyses of populational annual effective dose. The materials and methods. The survey was conducted in Tula Region since 1997 to 2015. Over that period, more than fifty thousand samples of the main foodstuffs from the post-Chernobyl contaminated area were analyzed. Simultaneously with that, the external gamma - radiation dose rate was measured in the fixed control points. The dynamics of cesium -137 and strontium-90 content in foodstuffs were assessed along with the maximum values of the mean annual effective doses to the population and the contribution of the collective dose from medical exposures into the structure of the annual effective collective dose to the population. The results. The amount of cesium-137 and strontium -90 in the local foodstuffs was identified. The external gamma- radiation dose rate values were found to be stable and not exceeding the natural fluctuations range typical for the middle latitudes of Russia’s European territory. The maximum mean annual effective dose to the population reflects the stable radiation situation and does not exceed the permissible value of 1 mSv. The contribution of the collective dose from medical exposures of the population has been continuously reducing as well as the average individual dose to the population per one medical treatment under the annual increase of the medical treatments quantities. The conclusion. There is no exceedance of the admissible levels of cesium-137 and strontium- 90 content in the local foodstuffs. The mean annual effective dose to the population has decreased which makes it possible to transfer the settlements affected by the Chernobyl NPP accident to normal life style. This is covered by the draft concept of the settlements’ transfer to normal life style.

    This research was performed in an area belonging to the province of the city of Bologna (Emilia-Romagna region, Northern Italy). The purpose of the present survey was to record the local knowledge concerning traditional uses of wild food plants and related practices, such as gathering, processing, cooking, therapeutic uses, with the aim of preserving an important part of the local cultural heritage. Thirty-nine people still retaining Traditional Local Knowledge (TLK) were interviewed between March-April 2012 and September-October 2013 by means of open and semi-structured ethnobotanical interviews. For each plant species mentioned, we recorded the botanical family, the English common name, the Italian common and/or folk names, the parts of the plant used, the culinary preparation, and the medicinal usage. The relative frequency of citation index (RFC), a tool that measures the local cultural importance of a plant species, was also included. The folk plants mentioned by the respondents belonged to 33 botanical families, of which the Rosaceae (14 plants) and the Asteraceae (9 plants) were the most representative. The species with the highest RFC index (0.77) were Crepis vesicaria subsp. taraxacifolia (Thuill) Thell and Taraxacum officinale Weber. Eleven folk plants were indicated as having therapeutic effects. T. officinale Weber, C. vesicaria subsp. taraxacifolia (Thuill) Thell and Sonchus spp., which are used as food, were reported to be depurative, blood cleaning, refreshing, diuretic and laxative. The most commonly used species was Urtica spp, which was also the most frequently cited for medicinal uses. The present survey documented the wild food plant traditional knowledge of an area belonging to the province of the city of Bologna (Emilia-Romagna region, Northern Italy). The general perception obtained is that on one side the TLK related to wild food plants has strongly been eroded, mainly due to immigration and urbanization phenomena, whereas on the other side

    The aim of this study was to determine the major components (Na, Ca, K, Mg, Fe, Al, NH 4+, SO 42-, NO 3-, Cl - and TC) and trace-metal levels (As, Ni, Cd, Pb, Ti, V, Cr, Mn, Cu, Mo, Rh and Hg) in PM 10 and PM 2.5 at an Atlantic coastal city (Santander, Cantabria region, Northern Spain). Additional samples were collected in other urban sites of the Cantabria region to assess the metal content found in different urban environments within the region. To control for the mass attributed to inland regional background particulate matter, samples were also collected in Los Tojos village. The spatial variability of the major PM components shows that PM origins are different at inland and coastal sites. In the coastal city of Santander, the most important contributors are (i) the marine aerosol and (ii) the secondary inorganic aerosol (SIA) and the total carbon (TC) in PM 10 and PM 2.5, respectively. Additionally, the influence of the coastal location on the ionic balance of PM is also studied. The trace metal spatial variability is studied using the coefficient of divergence (COD), which shows that the levels of trace metals at the three studied urban sites are mainly influenced by local emission sources. The main local tracers are identified as follows: Mn in the Santander area; Mo, Cr and Pb at Reinosa; and Ni and V at Castro Urdiales. A more detailed source apportionment study of the local trace metals at Santander is conducted by Principal Component Analysis (PCA) and Positive Matrix Factorisation (PMF); these two receptor models report complementary information. From these statistical analyses, the identified sources of trace metals in PM 10 are urban background sources, industrial sources and traffic. The industrial factor was dominated by Mn, Cu and Pb, which are trace metals used in steel production and manganese-ferroalloy production plant. With respect to PM 2.5, the identified emission sources of trace metals are combustion processes as well as traffic and

    Mental health patients boarding for long hours, even days, in United States emergency departments (EDs) awaiting transfer for psychiatric services has become a considerable and widespread problem. Past studies have shown average boarding times ranging from 6.8 hours to 34 hours. Most proposed solutions to this issue have focused solely on increasing available inpatient psychiatric hospital beds, rather than considering alternative emergency care designs that could provide prompt access to treatment and might reduce the need for many hospitalizations. One suggested option has been the "regional dedicated emergency psychiatric facility," which serves to evaluate and treat all mental health patients for a given area, and can accept direct transfers from other EDs. This study sought to assess the effects of a regional dedicated emergency psychiatric facility design known at the "Alameda Model" on boarding times and hospitalization rates for psychiatric patients in area EDs. Over a 30-day period beginning in January 2013, 5 community hospitals in Alameda County, California, tracked all ED patients on involuntary mental health holds to determine boarding time, defined as the difference between when they were deemed stable for psychiatric disposition and the time they were discharged from the ED for transfer to the regional psychiatric emergency service. Patients were also followed to determine the percentage admitted to inpatient psychiatric units after evaluation and treatment in the psychiatric emergency service. In a total sample of 144 patients, the average boarding time was approximately 1 hour and 48 minutes. Only 24.8% were admitted for inpatient psychiatric hospitalization from the psychiatric emergency service. The results of this study indicate that the Alameda Model of transferring patients from general hospital EDs to a regional psychiatric emergency service reduced the length of boarding times for patients awaiting psychiatric care by over 80% versus

    Regional groundwater flow of the Whiteshell Research Area (WRA) is simulated in order to evaluate alternative locations for a hypothetical nuclear fuel waste disposal vault that maximizes retention of vault contaminants in the geosphere, and to define boundary conditions for a smaller local model around the vault. A revised conceptual model of the hydrogeologic conditions was constructed using all the information obtained from field investigations at the WRA between 1977 and 1994. All the simulations were performed using AECL's three-dimensional finite-element code, MOTIF. Average values of hydraulic parameters obtained from the field data were used for a base-case simulation, in which freshwater was assumed to occur in the entire flow region. The simulated average groundwater recharge rate for this base case did not compare favourably with the recharge rate that was estimated from the field data. Model calibration was ultimately achieved by modifying the hydraulic parameters and total dissolved solids (TDS) distribution of the fluid in a series of consecutive simulations. The simulated recharge rate for the final calibrated model was 4.8 mm/a which compares well with the rate of 5 mm/a, that was estimated from independent field experiments. The simulated freshwater heads also compared reasonably well with measured heads in the network of boreholes at the WRA. Most of the groundwater flow occurred in local systems between the ground surface and the depth of 2000 m. The travel times, pathways and exit locations of particles released from different depth horizons in the groundwater velocity field of the calibrated model were determined using a particle tracking code, TRACK3D. These results were used to select a location for a hypothetical nuclear fuel waste disposal vault that maximizes the retention of vault contaminants in a long, slow groundwater flow pathways. The selected location is about 5 km northeast of the location of Underground Research Laboratory (URL

    Governments are increasingly establishing health regions to deal with current challenges of public health service. These regions are seen as instruments to balance public and private stakeholders, and offer health care to regional citizens as well as to medical/health tourists. However, it is still unclear how the development of such health regions as well as their governance may be conceptualized. We apply Luhmann's system theory approach in the context of a cross-regional case study that compares health region developments in the Autonomous Province of Bolzano-South Tyrol (Italy) with particular regard to the Eastern Dolomites and in the province of Zeeland (the Netherlands). We suggest that Luhmann's system theory provides a useful set of criteria to evaluate and judge health region development. Fully developed health regions can be understood as auto-poietic systems. By emphasizing programs, personnel, and communication channels, these case studies illustrate the suitability of the system theory toolset to analyze the governance and spatial embeddedness of health regions. Additionally, the study contributes to literature by indicating that health regions are closely related to identity issues and to decision making in regions. Copyright © 2014 Elsevier Ltd.

    Endemic goitre is still an important and underestimated health concern in Turkey. The overall prevalence had been calculated as 30.3% by palpation in a national survey conducted in 1995. However, direct evidence that iodine deficiency (ID) is the major cause of the endemic were lacking until now. We measured sonographic thyroid volumes (STV), urinary iodine concentrations (UIC) in 1226 school age children (SAC) (9-11 year old) from Ankara the capital of Turkey located in the central Anatolia, and three highly endemic goitre areas of the Black Sea region. A considerable number of school age children (SAC) were found to have STV exceeding the recommended upper normal limits for their age and gender obtained from iodine-replete European children (i.e. 26.7, 40.3, 44.8 and 51.7% of children from Ankara, Kastamonu, Bayburt and Trabzon respectively). UIC indicated moderate to severe ID in these areas with median concentrations of 25.5, 30.5, 16.0 and 14 μg/L respectively. This study showed severe to moderate ID as the primary etiological factor for the goitre endemic observed in Ankara and the Black Sea region of Turkey

    In rural areas with a low population density and (imminent) gaps in regional health care, telemedicine concepts can be a promising option in supporting the supply of medical care.Telemedicine connections can be established between different health care providers (e.g., hospitals) or directly between health care providers and patients.Different scenarios for the implementation of telemedicine have been developed, from the monitoring of chronically ill patients to the support of acute care. Examples of frequently applied telemedicine concepts are teleradiology, telemedicine stroke networks, and the telemedicine monitoring of patients with heart failure. The development of concepts for other indications and patient groups is apparently difficult in Germany; one reason could be that research institutions are involved in only a small number of projects. However, the participation of research institutes would be of importance in creating more scientific evidence. The development of appropriate evaluation designs for analyzing the effectiveness of telemedicine concepts and economic effects is an important task and challenge for the future. Mandatory evaluation criteria should be developed to provide a basis for the translation of positively evaluated telemedicine concepts into routine care.

    Full Text Available Wireless regional area network (WRAN adopts centralized network architecture and is currently one of the most typical cognitive radio networks. In order to reduce the energy consumption of the communication networks with the constraint of spectrum resource utilization, a working sleep mechanism is introduced into the base station (BS, and a novel energy saving strategy with dual rate transmission is proposed. Combining the multiple-vacation queue and priority queue, using the quasi-birth-death process and the matrix-geometric solution method, we assess the average latency and the forced termination probability of secondary user packets, as well as the energy saving ratio and the channel utilization of system. Based on the revenue-expenditure structure, a profit function is built, and then the Nash equilibrium behavior and the socially optimal behavior are investigated. With the help of the particle swarm optimization, an intelligent optimization algorithm to search the socially optimal arrival rate of secondary user packets is presented. In order to unify the arrival rates of secondary user packets with Nash equilibrium and social optimization, a reasonable pricing policy is formulated. In addition, system experiments are carried out to verify the effectiveness of the energy saving strategy and the rationality of the pricing policy.

    A review of the seismic history of Egypt indicates sone areas of high activity concentrated along Oligocene-Miocene faults. These areas support the idea of recent activation of the Oligocene-Miocene stress cycle. There are similarities in the special distribution of recent and historical epicenters. Form the tectonic map of Egypt, distribution of Intensity and magnitude show strong activity along Nile Delta. This due to the presence of a thick layers of recent alluvial sediments. The released energy of the earthquakes are effective on the structures. The present study deals with the computed released energies of the reported earthquakes in Egypt and around Inshas area . Its effect on the urban and nuclear facilities inside Inshas site is considered. Special consideration will be given to old and new waste repository sites. The application of the determined released energy reveals that Inshas site is affected by seismic activity from five seismo-tectonic source zones, namely the Red Sea, Nile Delta, El-Faiyum, the Mediterranean Sea and the Gulf of Aqaba seismo-tectonic zones. El-Faiyum seismo-tectonic source zone has the maximum effect on the site and gave a high released energy reaching to 5.4E +2 1 erg

    Full Text Available Dynamic development of international processes at the regional level, various trajectories of regionalization in Europe, Asia, Latin America and other parts of the world created a complex and multidimensional picture of the contemporary international relations. However Social Sciences and IR retained a distinct eurocentrism. This eurocentrism only partly meant that students of IR did not take into account non-European or non-Western realities. Thus, a German Scholar J. Vullers from German Institute of Global and Area Studies analyzing in 2014 three leading International Relations journals (International Organization, World Politics, European Journal of International Relations diagnosed a serious geographic imbalance in the international studies, which meant a very limited number of articles based on the nonWestern empirical data.Even with such geographic imbalance in IR studies more important for preserving eurocentrism there was the absence of non-Western IR theories or IR theories originating from non-Western political context. The collective monograph edited by Barry Buzan and Amitav Acharya focused exactly on this problem. The title of the book was provocatively asking why there is no non-Western IR theory. Thus, the book in question provoked a lively academic debate on the topic. Russia was not covered in this book. Therefore, this very fact gives one some reasons to reflect on how Russian research in the field may face a double challenge of a changing international environment and an inappropriate level of its intellectual assessment. Against this background this article analyzes World Regional Studies, a research framework and discipline, which is rapidly developing in Russia and may to some extent contribute to a more correct understanding of the international processes.

    The lower risk of cancer in the areas inhabited by the German minority in the region of Opole, Poland, at the turn of the 1980's and 1990's has been already reported. A reanalysis of the present-day data was conducted. All the cancer cases (at all sites combined) registered within the years 2008-2012 with data collected by the Regional Cancer Registry in Opole were analyzed in this study. To estimate the risk of cancer in different spatial contexts, such as trends, clusters, and levels, modern geostatistical tools were applied. A statistically significant reduction of the cancer risk was reported in administrative units with ≥ 10% of the German minority. Average decreases in relative risk of 13% in men and 16% in women were estimated. The geographical patterns of the estimates are illustrated. The observed differences in the risk of cancer between the ethnic groups (Germans and repatriates) confirm a historical trend of the disease in the region of Opole, Poland. Some genetic, nutritional, or cultural aspects together with economic issues may play a role in the specified spatial disease patterns. © 2015 S. Karger GmbH, Freiburg.

    2013-01-01

    Groundwater in the vicinity of several industrial facilities in Upper Gwynedd Township and vicinity, Montgomery County, in southeast Pennsylvania has been shown to be contaminated with volatile organic compounds (VOCs), the most common of which is the solvent trichloroethylene (TCE). The 2-square-mile area was placed on the National Priorities List as the North Penn Area 7 Superfund site by the U.S. Environmental Protection Agency (USEPA) in 1989. The U.S. Geological Survey (USGS) conducted geophysical logging, aquifer testing, and water-level monitoring, and measured streamflows in and near North Penn Area 7 from fall 2000 through fall 2006 in a technical assistance study for the USEPA to develop an understanding of the hydrogeologic framework in the area as part of the USEPA Remedial Investigation. In addition, the USGS developed a groundwater-flow computer model based on the hydrogeologic framework to simulate regional groundwater flow and to estimate directions of groundwater flow and pathways of groundwater contaminants. The study area is underlain by Triassic- and Jurassic-age sandstones and shales of the Lockatong Formation and Brunswick Group in the Mesozoic Newark Basin. Regionally, these rocks strike northeast and dip to the northwest. The sequence of rocks form a fractured-sedimentary-rock aquifer that acts as a set of confined to partially confined layers of differing permeabilities. Depth to competent bedrock typically is less than 20 ft below land surface. The aquifer layers are recharged locally by precipitation and discharge locally to streams. The general configuration of the potentiometric surface in the aquifer is similar to topography, except in areas affected by pumping. The headwaters of Wissahickon Creek are nearby, and the stream flows southwest, parallel to strike, to bisect North Penn Area 7. Groundwater is pumped in the vicinity of North Penn Area 7 for industrial use, public supply, and residential supply. Results of field investigations

    Full Text Available The understanding of the distribution and richness patterns of species is very important in ecology. Also, for the Cerrado region, this is very important and urgent, because of the strong pressure for new areas designated for agriculture. In five areas of the Cerrado, an exploratory study was carried out on the diversity, evenness and similarity of moth species. Moths were captured in a white sheet hung vertically and illuminated by a 250 Watt mercury vapor lamp. The alpha diversity was calculated using the Shannon-Wiener index (H' and the Simpson index (γ. The beta diversity was examined for all sampled localities and estimated by Wittaker's measure. The Sörensen and Jaccard indexes were used to calculate similarity. A total of 11130 individuals, 1064 species and 33 families were collected during the study. Great differences were found in the diversity (H', and according to this index, the minimum value found was 1.60 and highest value was 4.59. From the Simpson index (γ, the minimum value was 0.42 and highest 0.96. With both methods, in all the localities, these values were significantly different by the T test (p<0.001. The mean beta diversity found was 0.6929, and the minimum and highest values found were respectively 0.4328 and 0.8615. A positive correlation was found between beta diversity and distances among the localities (r²=0.5844, p<0.05. Faunal similarities among sites were low, and the highest value found was 0.4146 by Sörensen index and 0.2615 by Jaccard index.

    According to the current archeological investigations Ada Tepe is the oldest gold mine in Europe with Late Bronze and Early Iron age. It is a typical low-sulfidation epithermal gold deposit and is hosted in Maastrichtian-Paleocene sedimentary rocks above a detachment fault contact with underlying Paleozoic metamorphic rocks. Ada Tepe (25o.39'E; 41o.25'N) is located in the Eastern Rhodope unit. The region is highly segmented despite the low altitude (470-750 m) due to widespread volcanic and sediment rocks susceptible to torrential erosion during the cold season. Besides the thorough geological exploration focused on identifying cost-effective stocks of mineral resources, a detailed geophysical analysis concernig diferent stages of the gold extraction project was accomplished. We present the main results from the geophysical investigation aimed to clarify the complex seismotectonic setting of the Ada Tepe site region. The overall study methodology consists of collecting, reviewing and estimating geophysical and seismological information to constrain the model used for seismic hazard assessment of the area. Geophysical information used in the present work consists of gravity, geomagnetic and seismological data. Interpretation of gravity data is applied to outline the axes of steep gravity transitions marked as potential axes of faults, flexures and other structures of dislocation. Direct inverse techniques are also utilized to estimate the form and depth of anomalous sources. For the purposes of seismological investigation of the Ada Tepe site region an earthquake catalogue is compiled for the time period 510BC - 2011AD. Statistical parameters of seismicity - annual seismic rate parameter, ?, and the b-value of the Gutenberg-Richter exponential relation for Ada Tepe site region, are estimated. All geophysical datasets and derived results are integrated using GIS techniques ensuring interoperability of data when combining, processing and visualizing obtained

    The Alaska North Slope offers one of the best prospects for increasing U.S. domestic oil and gas production. However, this region faces some of the greatest environmental and logistical challenges to oil and gas production in the world. A number of studies have shown that weather patterns in this region are warming, and the number of days the tundra surface is adequately frozen for tundra travel each year has declined. Operators are not allowed to explore in undeveloped areas until the tundra is sufficiently frozen and adequate snow cover is present. Spring breakup then forces rapid evacuation of the area prior to snowmelt. Using the best available methods, exploration in remote arctic areas can take up to three years to identify a commercial discovery, and then years to build the infrastructure to develop and produce. This makes new exploration costly. It also increases the costs of maintaining field infrastructure, pipeline inspections, and environmental restoration efforts. New technologies are needed, or oil and gas resources may never be developed outside limited exploration stepouts from existing infrastructure. Industry has identified certain low-impact technologies suitable for operations, and has made improvements to reduce the footprint and impact on the environment. Additional improvements are needed for exploration and economic field development and end-of-field restoration. One operator-Anadarko Petroleum Corporation-built a prototype platform for drilling wells in the Arctic that is elevated, modular, and mobile. The system was tested while drilling one of the first hydrate exploration wells in Alaska during 2003-2004. This technology was identified as a potentially enabling technology by the ongoing Joint Industry Program (JIP) Environmentally Friendly Drilling (EFD) program. The EFD is headed by Texas A&M University and the Houston Advanced Research Center (HARC), and is co-funded by the National Energy Technology Laboratory (NETL). The EFD

  14. Hydrodynamic characteristics of the western Doñana Region (area of El Abalario), Huelva, Spain

    Trick, Thomas; Custodio, Emilio

    The Doñana region, in southwestern Spain, comprises a large and important nature reserve, the wetlands of which are affected by human activity. Planting of an extensive eucalyptus forest in the 1950s and, more recently, the use of aquifers for irrigation and water supply for some coastal tourist resorts, have altered the natural groundwater-flow system. The area of the study is the western sector of the region, called El Abalario, which is a gentle topographic elevation between the Atlantic coast and La Rocina Creek (Arroyo de la Rocina). Underneath a variable layer of eolian sands with high dunes near the coast, thick Plio-Quaternary detritic strata, mostly fine silica sands, overlie marls. Near the base there is a variable, deltaic-origin layer of coarse sands and gravels. The dome-shaped water table, inside the sands, is close to the surface everywhere except beneath the dune belt, and small, temporary, shallow lagoons are numerous. The coarse sand and gravel layer conditions groundwater flow and behaves as a semiconfined layer between sands. A cross section through the area was simulated with a model to check the validity of the conceptual groundwater-flow pattern and its sensitivity to the hydraulic parameters. The model was calibrated using parameter values obtained by pumping tests and multilevel piezometric data, and checked against the estimated groundwater discharge into La Rocina Creek. Groundwater flows peripherally to the sea coast, to La Rocina Creek, or directly east and southeastward into the Doñana marshlands, in the Guadalquivir River delta. The average net aquifer recharge rate was calculated to be between 100 and 200 mm year-1 for the area covered by brush, but is remarkably lower in the areas of eucalyptus trees. The transient-state model shows that recharge varies spatially and is not clearly proportional to annual precipitation. Phreatic evapotranspiration plays an important role in decreasing the net value of aquifer recharge to

    Full Text Available Quarry sites result from human activity, which includes the removal of original vegetation and the overlying soil to dig out stones for building use. Therefore, the dynamics of the quarry area provide a unique view of human mining activities. Actually, the topographic changes caused by mining activities are also a result of the development of the local economy. Thus, monitoring the quarry area can provide information about the policies of the economy and environmental protection. In this paper, we developed a combined method of machine learning classification and quarry region analysis to estimate the quarry area in a quarry region near Beijing. A temporal smoothing based on the classification results of all years was applied in post-processing to remove outliers and obtain gently changing sequences along the monitoring term. The method was applied to Landsat images to derive a quarry distribution map and quarry area time series from 1984 to 2017, revealing significant inter-annual variability. The time series revealed a five-stage development of the quarry area with different growth patterns. As the study region lies on two jurisdictions—Tianjin and Hebei—a comparison of the quarry area changes in the two jurisdictions was applied, which revealed that the different policies in the two regions could impose different impacts on the development of a quarry area. An analysis concerning the relationship between quarry area and gross regional product (GRP was performed to explore the potential application on socioeconomic studies, and we found a strong positive correlation between quarry area and GRP in Langfang City, Hebei Province. These results demonstrate the potential benefit of annual monitoring over the long-term for socioeconomic studies, which can be used for mining decision making.

    Fluorine (F) is a topic of great interest in coal-combustion related endemic fluorosis areas. However, little extent research exists regarding the environmental geochemistry of toxic elements that are enriched in coals and coal wastes in traditional endemic fluorosis areas, particularly focusing on their occurrences and mobilities during the weathering-leaching processes of coals and coal wastes in the surface environment. This paper addressed the issue of toxic elements in coals and coal wastes in the Three Gorges Region, Southwest (SW) China, where endemic fluorosis has historically prevailed, and investigated the distribution, occurrence, mobility features, and associated potential health risks. For this purpose, a modified experiment combined with long-term humidity cell test and column leaching trial was applied to elucidate the mobility of toxic elements in coals and coal wastes. In addition, sequential chemical extraction (SCE) was used to ascertain the modes of occurrence of toxic elements. The results demonstrated that the contents of toxic elements in the study area followed the order: stone coals > gangues > coal balls > coals. Furthermore, modes of occurrence of toxic elements were obviously different in coals and coal wastes. For example, cadmium (Cd) was mainly associated with monosulfide fraction in coals, molybdenum (Mo) and arsenic (As) were mainly associated with carbonate and silicate in coal gangues and stone coals, chromium (Cr) mainly existed in silicate and insoluble matter in coal gangues and coal balls, thallium (Tl) mainly occurred in organic matter in stone coals and sulfide in coals, and the occurrence of antimony (Sb) varied with different kinds of samples. Moreover, a large amount of toxic elements released to the leachates during the weathering and leaching process, which might pollute the environment and threaten human health. Based on the geo-accumulation index (I geo ), single factor index (P i ) and Nemerow index (P N ), soils i n

    Oil production in a steppe region disturbs the landscape and damages the steppe ecosystem. The objective of this research was to detect areas damaged by oil production in an oil field within the Russian Volga-Ural steppe region using winter Landsat imagery. We developed a practicable and effective approach using winter snow season multispectral Landsat satellite imagery. To this end, we applied seven algorithms of spectral or texture-based transformation: K-means, maximum likelihood estimation, topsoil grain size index, soil brightness, normalized differential snow index, tasselled cap, and co-occurrence measures. The co-occurrence texture measure variance shows the optimal result of identifying damaged areas. The unique feature of our method is that it can differentiate damaged areas from the bare soil of cropland within a cold steppe region where the area damaged by oil production is mixed with bare (fallow) croplands that have a polygonal shape similar to well pads. Such similarities can lead to confusion in object-based classification. Using the co-occurrence measures, we found that from 1988 to 2015, damaged area is nearly three times as big in the peak period of the oil field development (2001 and 2009) as in 1988. Landscape fragmentation also peaked in 2001 and 2009. Our approach for this project is useful and cost effective regular monitoring of damages from oil production for both the Volga-Ural steppe region and other cold steppe regions.

    Analyses of data on the transcapillary exchange and cellular uptake in the normal heart have generally been based on the assumption that local membrane conductances and volumes of distribution are everywhere the same. The question is whether such an assumption is justified in view of the marked (sixfold) heterogeneity of local blood flows per gram tissue. The method was to estimate both flow and capillary membrane permeability-surface area products (PS) locally in the heart. For each of five dogs running on a sloped treadmill, the deposition of tracer microspheres and of [131I]iodophenylpentadecanoic acid (IPPA), after left atrial injection, was determined in 256 pieces of left ventricular myocardium by killing the animals at approximately 100 s after radiotracer injection. A hydraulic occluder stopped the flow to a portion of the myocardium supplied by the left circumflex coronary artery 30 s before tracer injection. Regional flows ranged from 0.1 to 7.0 ml.g-1.min-1. IPPA extractions ranged from 20 to 49%. Using the known flows, we assumed the applicability of an axially distributed blood-tissue exchange model to estimate the PS for the capillary (PSc) and the parenchymal cell. It was impossible to explain the data if the PSc values for membrane transport were uniform throughout the organ. Rather, the only reasonable descriptors of the data required that local PSc values increase with local flow, almost in proportion. Current methods of analysis using data based on deposition methods need to be revised to take into account the near proportionality of PS to flow for at least some substrates.

    The aim of the environmental epidemiologic study was to determine possible negative effects on the health of children in the very polluted areas of Bitterfeld and Hettstedt in comparison to the less polluted areas of Anhalt-Zerbst (Eastern Germany). The time changes of the health parameters were recorded along with the running redevelopments during the time period of 6 years. The study design consisted of three repeated regional cross sectional studies in 1992/93, 1995/96 and 1998/99. In all, there was information of 7.611 questionnaires to be analysed (participation rate: 89%, 75% and 75%). Children living in the most polluted area of Hettstedt had a noticeable higher risk for non allergic respiratory diseases and symptoms compared to children living in the control area of Anhalt-Zerbst. During the time of the examinations in 1992 till 1999 a clear statistically significant decrease in the prevalences of these restrictions of health could be shown. Children without indoor pollutants in their homes profited most by the improvement of ambient air quality. The better lung function (FVC, FEV{sub 1}) between 1992 and 1999 underlines the improvement of the respiratory health. Children living in both polluted ares have allergies more often (physician's diagnosis, symptoms, allergy specific antibodies). The incidence of asthma, the bronchial hyperreactivity and atopic exzema increased, the prevalence of rhinitis and allergic sensitization did not increase. The body burden with lead and cadmium was higher in children living in polluted areas, but it decreased during the period of observation. In 1997, however, the lead concentration in blood increased a little, parallel to the higher lead concentration in settled dust in Hettstedt at that time. (orig.)

    Full Text Available ABSTRACT Visceral leishmaniasis (VL has spread rapidly across cities in the metropolitan region of Belo Horizonte. The aim of this study was to investigate VL dynamics in a prospective cohort study of dogs in Juatuba, between 2010 and 2011, to confirm the incidence of Leishmania infantum, and to assess possible risk factors associated with infection. An observational and prospective closed cohort study was performed using serology testing in dogs, randomly selected from the whole municipality. All seronegative dogs, or dogs with inconclusive results were monitored using indirect immunofluorescence (IIF at 6-month intervals. The dog's owners completed a semi-structured questionnaire to assess possible causal factors of seroconversion, and the responses were assessed using logistic regression. The canine incidence coefficient was 206/1,000 dogs per year (CI: 178-238, and a cluster was identified in an area with a high concentration of seropositive dogs, but a low overall canine population. Large dogs were identified as a risk factor and the following variables were identified as protection factors: dogs aged over 4 years, daily peridomicile cleaning, and better socioeconomic conditions. VL is spreading over a large area in Juatuba in a short period of time.

    The Swedish Nuclear Fuel and Waste Management Company (SKB) carries out site investigations in two different candidate areas in Sweden with the objective of describing the in-situ conditions for a bedrock repository for spent nuclear fuel. The site characterisation work is divided into two phases, an initial site investigation phase (IPLU) and a complete site investigation phase (KPLU). The results of IPLU are used as a basis for deciding on a subsequent KPLU phase. On the basis of the KPLU investigations a decision is made as to whether detailed characterisation will be performed (including sinking of a shaft). An integrated component in the site characterisation work is the development of site descriptive models. These comprise basic models in three dimensions with an accompanying text description. Central in the modelling work is the geological model, which provides the geometrical context in terms of a model of deformation zones and the rock mass between the zones. Using the geological and geometrical description models as a basis, descriptive models for other geo-disciplines (hydrogeology, hydro-geochemistry, rock mechanics, thermal properties and transport properties) will be developed. Great care is taken to arrive at a general consistency in the description of the various models and assessment of uncertainty and possible needs of alternative models. Here, a numerical model is developed on a regional-scale (hundreds of square kilometres) to understand the zone of influence for groundwater flow that affects the Forsmark area. Transport calculations are then performed by particle tracking from a local-scale release area (a few square kilometres) to identify potential discharge areas for the site and using greater grid resolution. The main objective of this study is to support the development of a preliminary Site Description of the Forsmark area on a regional-scale based on the available data of 30 June 2004 and the previous Site Description.

    A comprehensive geochemical environmental study focused on topsoil, groundwater, vegetable (corn) and human hair samples has been carried out in the Domizio-Flegreo Littoral and Agro Aversano areas in Southern Italy, covering 1287 km2 and including 90 municipalities. Within the framework of thethis study a focus was also carried on some specific sites (Teverola, Trentola-Ducenta, Giugliano, Castelvolturno and Acerra), that may have been affected by different sources of pollution (industrial and agricultural) and by the large presence of illegal buried waste disposals. Among the industrial sites that are expected to contribute to the contamination of the region a car and a chemical factory producing polyester fibres could be taken into account together with an urban waste incineration plant that is in operation since 2009 within the Acerra municipality administrative area. The research is based on 1064 topsoil samples, 27 groundwater samples, 24 samples of human hair and 13 corn samples taken in across the whole study area. Although samples were analysed for 53 elements at ACME Analytical Laboratories (Vancouver, Canada) by means of ICP-MS and ICP-ES after an aqua regia digestion, we focused on 15 key elements (As, Be, Cd, Co, Cr, Cu, Hg, Ni, Pb, Sb, Se, Sn, Tl, V and Zn), for which the Italian Environmental Law 152/06 establishes trigger and action limits for both residential/recreational and industrial/commercial land use, based on the risks to human health. All the chemical data were statistically treated and dot and interpolated maps were produced by means of the GeoDAS software. Maps showing the distribution of contamination factors (1) (Hakanson,1980) for each key element were also created. In general, As, Pb, Cr, Cd and Hg resulted to be the most critical pollutants for the area. Furthermore, Pb isotopic analyses on soil, water, corn and hair were conducted in order to distinguish between possible sources of contamination and geogenic and/or anthropogenic

    Central Bohemian Region is located in a shape of a ring surrounding the capitol of Prague. Its total territorial area is 11.014 sq.km and population of 1 130.000 inhabitants. According to EU nomenclature of regional statistical units, the Central Bohemian Region is classified as an independent NUTS II. Bohemia's biggest rivers, Vltava and Labe form the region's backbone dividing it along a north-south line, besides that there are Sazava and Berounka, the two big headwaters of Vltava, which flow through the region and there also are some cascade man made lakes and 2 important big dams - Orlik and Slapy on the Vltava River in the area of the region. Overflowing of these rivers and their feeders including cracking of high-water dams during the floods in August 2002 caused total or partial destruction or damage of more than 200 towns and villages and total losses to the extend of 450 mil. EUR. The worst impact was on damaged or destroyed human dwellings, social infrastructure (schools, kindergartens, humanitarian facilities) and technical infrastructure (roads, waterworks, power distribution). Also businesses were considerably damaged including transport terminals in the area of river ports. Flowage of Spolana Neratovice chemical works caused critical environmental havoc. Regional crisis staff with regional Governor in the lead worked continuously during the floods and a regional integrated rescue system was subordinated to it. Due to the huge extent of the floods the crisis staff coordinated its work with central bodies of state including the Government and single "power" resorts (army, interior, transport). Immediately after floods a regional - controlled management was set up including an executive body for regional revitalisation which is connected to state coordinating resort - Ministry for Local Development, EU sources and humanitarian aid. In addition to a program of regional revitalisation additional preventive flood control programs are being developed

    Water flow behaviour of Pampeano aquifer was modeled using Visual Mod-flow software Package 2.8.1 with the assumption of a free aquifer, within the region of the Areco river and extending to the rivers of 'Canada Honda' and 'de la Cruz'. Steady state regime was simulated and grid refinement allows obtaining locally detailed calculation in the area of Atucha I and II Nuclear power plants, in order to compute unsteady situations as the consequence of water flow variations from and to the aquifer, enabling the model to study the movement of possible contaminant particles in the hydrogeologic system. In this work the effects of rivers action, the recharge conditions and the flow lines are analyzed, taking always into account the range of reliability of obtained results, considering the incidence of uncertainties introduced by data input system, the estimates and interpolation of parameters used.

    Six different locations :Inshas, Shebeen, Abu-Zaabal, Al-Oboor in addition to two sites in the Nuclear Research Centre (NRC), (Old reactor and Protection department sites), in Egypt at Inshas region and the area nearby (about 30 Km radius) were selected for collection of plant samples , together with their corresponding soils. Natural radionuclides concentration in different environmental samples of plants especially grasses ,)leaves of old trees) and soils, were determined using high resolution gamma- spectroscopy (Hyper Pure Germanium detector).Natural uranium-238 and thorium -232 together with their decay products were determined as well as K-40. Also, Cs-137 radiation level was determined as an indication of the contamination from the fallout. It is noticed that the obtained results for all plants and grasses in the present study are higher than those obtained for their corresponding soils (except for Shebeen), which has nearly the same average concentration value of K-40 in plants and their corresponding soils

    Full Text Available Conservation scientists recognize that additional protected areas are needed to maintain biological diversity and ecological processes. As regional conservation planners embark on recommending additional areas for protection in formal ecological reserves, it is important to evaluate candidate lands for their role in building a resilient protected areas system of the future. Here, we evaluate North Carolina’s Mountain Treasures with respect to their (1 ecological integrity, (2 role in connecting existing core protected areas, (3 potential to diversify the ecosystem representation of reserves, and (4 role in maintaining hotspots of biologically-rich areas that are not well protected. Mountain Treasures represent a citizen inventory of roadless areas and serve as candidates for elevated levels of conservation protection on U.S. federal lands. We compared Mountain Treasures to other candidate lands throughout the country to evaluate their potential national significance. While the Mountain Treasures tended to be more impacted by human modifications than other roadless areas, they are as important as other roadless areas with respect to their role in connecting existing protected areas and diversifying representation of ecosystems in conservation reserves. However, Mountain Treasures tended to have a much higher biodiversity priority index than other roadless areas leading to an overall higher composite score compared to other roadless areas. Our analysis serves as an example of how using broad-scale datasets can help conservation planners assess the national significance of local areas.

  13. The socio-economic impacts on regional areas as a result of new nuclear construction and nuclear decommissioning

    Large social and economic impacts are caused by new nuclear construction and eventual shutdown of operations and decommissioning. When new construction begins, the impact on the local area is enormous. The influx of construction workers and businesses to provide services and goods usually overwhelms the area which previously may have had a minimal amount of infrastructure and little population. Also, given that many of the current nuclear facilities worldwide are located in somewhat remote regions, they have become the primary source of jobs for those regions. When these facilities shut down and go into decommissioning, there can be several adverse effects upon the region or area. This paper will address some of the primary socio-economic influences of both new nuclear construction and subsequent decommissioning. (author)

    2000-02-11

    A regional groundwater flow model encompassing approximately 100 mi2 surrounding the C, K, L, and P reactor areas has been developed. The reactor flow model is designed to meet the planning objectives outlined in the General Groundwater Strategy for Reactor Area Projects by providing a common framework for analyzing groundwater flow, contaminant migration and remedial alternatives within the Reactor Projects team of the Environmental Restoration Department. The model provides a quantitative understanding of groundwater flow on a regional scale within the near surface aquifers and deeper semi-confined to confined aquifers. The model incorporates historical and current field characterization data up through Spring 1999. Model preprocessing is automated so that future updates and modifications can be performed quickly and efficiently. The CKLP regional reactor model can be used to guide characterization, perform scoping analyses of contaminant transport, and serve as a common base for subsequent finer-scale transport and remedial/feasibility models for each reactor area.

    Full Text Available Recent studies have intended to quantify urban consumption and trade in Amazonian towns. However, little is still known about the different ways in which bushmeat is made available in urban areas, including commercial and noncommercial flows, and how those flows contribute to link forests to urban livelihoods. In this study we qualitatively describe the structure and functioning of bushmeat flows in terms of species, catchment area, stakeholders involved, and the motivations for their activity in the main towns of the Amazon trifrontier region between Brazil, Colombia, and Peru. We show that bushmeat trade to urban areas exists under an organized but invisible commodity chain providing a source of income to about 195 persons. Bushmeat is made available either directly from the hunter to the urban consumer, at the main market place, or in food stalls and restaurants. On the Colombian border, the trade is totally invisible, whereas in Peru and Brazil, bushmeat is sold in open markets despite regulations. The catchment area comprises the main rivers: up to Caballococha along the Amazon River, along the Atacuary River in Peru, along the Javari River between Peru and Brazil, and along the Loretoyacu and Amacayacu rivers in Colombia and in periurban forests. Although the trade is rather localized (no commercial flows to larger towns, international transborder trade is commonplace, disregarding Convention on International Trade in Endangered Species of Wild Fauna and Flora regulations. Bushmeat clients in urban areas are mainly nonindigenous or mestizos who can afford bushmeat as a luxury meal. Instead, indigenous people in urban areas do not access bushmeat through the market but rather through their social networks with whom they maintain noncommercial flows including immediate exchange and long-term exchange mechanisms. Although bushmeat is no longer consumed as a daily meal among urban and periurban indigenous families, it constitutes what could be

    In 1995 and 1997, experimental decontamination campaigns were carried out in two recreational areas, Novie Bobovichi and Guta-Muravinka, near the town of Novozybkov, Bryansk Region, Russia. These areas were strongly affected by the Chernobyl fallout in 1986. In order to examine the long-term stability of the clean-up procedures, a programme has been carried out to continuously monitor the radiological situation in and around the decontaminated areas. This follow-up program consists of regular (1-3 times per year) measurements of absorbed gamma-dose rate in air (DR) at reference indoor and outdoor locations, repeated DR measurements on a grid, and gamma-spectrometric analysis of soil and other environmental samples. Very similar dynamics of the Chernobyl-related DR, mostly attributed to radiocaesium decay, were found in all the locations. For the period under study (September 1995-May 2003), the half-lives (years) for the reduction in radiocaesium-dependent DR contribution due to contaminant migration (in the following termed 'DRM half-lives') were, respectively, 52 ± 26, 57 ± 23, 43 ± 21, 46 ± 15, and 80 ± 56 for the following locations: untreated outdoors, treated outdoors, untreated indoors, treated indoors, and undisturbed forest-grassland plots outside the recreational areas. These relatively high values of the current DRM half-lives correspond very well with the results of soil core analyses, which showed no time-dependent changes in the mean mass depths of the 137 Cs distribution, neither at treated nor at undisturbed plots. The following signs of natural restoration of the disturbed forest-meadow ecosystems have been observed at treated areas: formation of a new litter layer, development of grassy spots, mushroom growths and new generations of pines and birches. The levels of the 137 Cs content in grass and mushrooms from treated plots were one or two orders of magnitude lower, than those registered in the samples from untreated areas. The follow

    To examine the characteristics of sap flow in Quercus liaotungensis and their response to environmental factors under different soil moisture conditions, Granier-type thermal dissipation probes were used to measure xylem sap flow of trees with different sapwood area in a natural Q. liaotungensis forest in the loess hilly region. Solar radiation, air temperature, relative air humidity, precipitation, and soil moisture were monitored during the study period. The results showed that sap flux of Q. liaotungensis reached daily peaks earlier than solar radiation and vapor pressure deficit. The diurnal dynamics of sap flux showed a similar pattern to those of the environmental factors. Trees had larger sap flux during the period with higher soil moisture. Under the same soil moisture conditions, trees with larger diameter and sapwood areas had significantly higher sap flux than those with smaller diameter and sapwood areas. Sap flux could be fitted with vapor pressure deficit, solar radiation, and the integrated index of the two factors using exponential saturation function. Differences in the fitted curves and parameters suggested that sap flux tended to reach saturation faster under higher soil moisture. Furthermore, trees in the smaller diameter class were more sensitive to the changes of soil moisture. The ratio of daily sap flux per unit vapor pressure deficit under lower soil moisture condition to that under higher soil moisture condition was linearly correlated to sapwood area. The regressive slope in smaller diameter class was larger than that in bigger diameter class, which further indicated the higher sensitivity of trees with smaller diameter class to soil moisture. These results indicated that wider sapwood of larger diameter class provided a buffer against drought stress.

    Health care spending increases sharply at the end of life. Little is known about variation of cost of end of life care between regions and the drivers of such variation. We studied small-area patterns of cost of care in the last year of life in Switzerland. We used mandatory health insurance claims data of individuals who died between 2008 and 2010 to derive cost of care. We used multilevel regression models to estimate differences in costs across 564 regions of place of residence, nested within 71 hospital service areas. We examined to what extent variation was explained by characteristics of individuals and regions, including measures of health care supply. The study population consisted of 113,277 individuals. The mean cost of care during last year of life was 32.5k (thousand) Swiss Francs per person (SD=33.2k). Cost differed substantially between regions after adjustment for patient age, sex, and cause of death. Variance was reduced by 52%-95% when we added individual and regional characteristics, with a strong effect of language region. Measures of supply of care did not show associations with costs. Remaining between and within hospital service area variations were most pronounced for older females and least for younger individuals. In Switzerland, small-area analysis revealed variation of cost of care during the last year of life according to linguistic regions and unexplained regional differences for older women. Cultural factors contribute to the delivery and utilization of health care during the last months of life and should be considered by policy makers.

    Tracer experiments are being conducted to verify atmospheric transport and dispersion calculations at distances from tens to hundreds of km from pollutant sources. In one study, a 2 1/2 year sampling program has been carried out at 13 sites located 30 to 140 km from a source of 85 Kr at the Savannah River Plant in South Carolina. Average weekly concentrations as well as twice-daily concentrations were obtained. Sampling data and meteorological data, including surface, tower, and rawinsonde observations are available on magnetic tape for model verification studies. Some verification results for the Air Resources Laboratories Atmospheric Transort and Dispersion Model (ARL-ATAD) are shown for averaging periods from one week to two years

    Biosphere assessment forms one of the main components in Posiva's Safety Case portfolio and includes analyses of terrain and ecosystem development. Shoreline displacement and changes in surface hydrology form one part of these analyses. In this report, the regional development of the Olkiluoto-Pyhaejaervi area in the time period 2000 BP - 8000 AP was examined by taking into account changes in the surface flow patterns of the Lapinjoki and Eurajoki river basins. A hydrological model, EULA, was developed and applied to investigate the past and future hydrological regimes and changes in the Olkiluoto-Pyhaejaervi study area. As detailed assessment of erosion and sedimentation effects were not within the scope of this study, only their general effects were evaluated. The digital elevation models (DEM) for different time stages (2000, 1500, 1000 and 500 BP; 100, 300, 500, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500, 5000, 6000, 7000 and 8000 AP) were compiled taking into account the land uplift and tilting of the Earth's crust. With the aid of various sophisticated GIS tools, the boundaries of the main river basins, the flow patterns of rivers and development of lakes during each stage were modelled. The yearly discharge rates of rivers Eurajoki and Lapinjoki were also evaluated with the assumption that present climatic features prevail during the whole time period 2000 BP - 8000 AP. Finally, the probability of significant changes in the surface water flow routes were estimated during different stages. (orig.)

    Full Text Available Roads, highways and streets are fundamental infrastructure facilities to provide the transportation for passenger travel and goods movement from one place to another in Sylhet, north–eastern division of Bangladesh with rapid growth of road vehicle, being comparatively developed economic tourist prone area faces severe road traffic accident. Such severe road accidents cause harsh safety hazards on the roads of Sylhet area. This research work presents an overview of the road traffic accident and degraded road safety situation in Sylhet zone which in particular, discusses the key road accident problem characteristics identifying the hazardous roads and spots, most responsible vehicles and related components, conditions of drivers and pedestrians, most victims of accident, effects of accident on society, safety priorities and options available in Sylhet. In this regard, a comprehensive questionnaire survey was conducted on the concerned groups of transportation and detailed accident data was collected from a popular local newspaper. Analysis of the study reveals that Dhaka- Sylhet highway is the most hazardous in road basis and Sylhet Sador thana is the most vulnerable in thana basis in Sylhet region.

    Moessbauer spectroscopy was applied to study the influence of industrial activity on soil composition. Comparing the Moessbauer spectra of separate layers for the Mariupol sampling site (highly polluted industrial region of South -- East Ukraine) we observed: i) appearance of the Fe3O4 compound at top soil layers: 16.6% of relative spectral area (RA) at (0 - 10 cm) layer, 5.3% of RA at (30 - 40 cm) layer and no magnetite component at deeper layers, ii) a significant increase of the contribution of the magnetically split spectral components: from 10.9% of RA for (120 - 130 cm) layer to 32.8% of RA for (0-10 cm) layer. The differences in RA of the magnetically split spectral components between top soil layer and the (120 - 130 cm) layer at the Homutovski steppe sampling site (non-polluted area) are much smaller, 13.7% and 9.8%, respectively. From the temperature dependence of the Moessbauer spectra it was concluded that part of the iron-containing compounds appears in the form of ultra fine particles in the superparamagnetic state. The observed increase of total concentration of the magnetic minerals for polluted sampling sites is caused by an increase of the content of coarse fraction of the magnetic particles

    The paper presents the results of study, analysis and forecast of the demographic effects of the Chernobyl accident in the most contaminated areas in the Kaluga region. A uniform technique was used for the study. The rural settlements with 1-15 Cu/m 2 radioactive contamination density were examined. The rural population of the Borovsk area free from the radioactive contamination was used as a control area. The period of examination - from 1981 up to 1990. The following indices were studied: birth rate and child mortality, stillbirth, ratio of born sexes, survival of children. It was determined that irradiation of the population resulted from the Chernobyl accident at the given moment does not affect the demographic situation in the region

    More than half of the world's population lives in cities, a proportion expected to increase to two thirds by 2050 (United Nations (UN), 2015). In this study, we investigate the spatial relationships that may exist between income and/or nationality homogeneity/heterogeneity levels of urban populations and their accessibility to local green-blue areas as possible nature-based solutions for sustainable urban design. For this investigation, we consider as a concrete case study the urban region of Stockholm, Sweden, for which we compile and use available land-cover and vegetation density data (the latter in terms of Normalised Difference Vegetation Index, NDVI) in order to identify and assess the spatial distributions of various green-blue area types and aspects. We further combine this data with spatial distribution data for population density, income and nationality, as well as with road-network data for assessing population travel times to nearby green-blue areas within the region. The present study results converge with those of other recent studies in showing large socio-economic-ethnic segregation in the Stockholm region. Moreover, the present data combination and analysis also show large spatial differences in and important socio-economic-ethnic correlations with accessibility to local green areas and nearby water bodies. Specifically, population income and share of Swedish nationals are well correlated in this region, with increases in both of these variables implying greater possibility to choose where to live within the region. The living choices of richer and more homogeneous (primarily Swedish) population parts are then found to be areas with greater local vegetation density (local green areas as identified by high-resolution NDVI data) and greater area extent of nearby water bodies (blue areas). For comparison, no such correlation is found between increased income or Swedish nationality homogeneity and accessibility to nearby forest areas (overall green

    Full Text Available The present study deals with the Ethno-medicinal plants used by the local communities in Santragachhi area, under Howrah Municipal Corporation, ward no. 38, District Howrah, West Bengal, India. An ethno medicinal survey was carried out the use of medicinal plants in Santragachi region. The information was gathered from the local community people using an integrated approach botanical collections, group discussion and interview with questionnaire during 2012-2013. Among 50 informants interviewed, 10 were tribal practitioners. A total of 53 genera and 33 families are documented. In most of case, fresh parts of the plants were used for the preparation of medicine. The results further revealed that the natives of this area are not very much practiced in using the medicinal plants in the treatment of human illness. The study area is delimited by number of wetlands and the people collect the aquatic plants by their habitual knowledge as food resources. But due to expansion of city area, road construction causes loss of plant diversity and random exploitation of natural resources many valuable medicinal plants are at the stage of extinction. The present study documented ethno medicinal plants were mostly used for treatment of various diseases.

    To assess the geographic distribution of Low Birth Weight (LBW) in New York State among singleton births using a spatial regression approach in order to identify priority areas for public health actions. LBW was defined as birth weight less than 2500g. Geocoded data from 562,586 birth certificates in New York State (years 2008-2012) were merged with 2010 census data at the tract level. To provide stable estimates and maintain confidentiality, data were aggregated to yield 1268 areas of analysis. LBW prevalence among singleton births was related with area-level behavioral, socioeconomic and demographic characteristics using a Poisson mixed effects spatial error regression model. Observed low birth weight showed statistically significant auto-correlation in our study area (Moran's I 0.16 p value 0.0005). After over-dispersion correction and accounting for fixed effects for selected social determinants, spatial autocorrelation was fully accounted for (Moran's I-0.007 p value 0.241). The proportion of LBW was higher in areas with larger Hispanic or Black populations and high smoking prevalence. Smoothed maps with predicted prevalence were developed to identify areas at high risk of LBW. Spatial patterns of residual variation were analyzed to identify unique risk factors. Neighborhood racial composition contributes to disparities in LBW prevalence beyond differences in behavioral and socioeconomic factors. Small-area analyses of LBW can identify areas for targeted interventions and display unique local patterns that should be accounted for in prevention strategies. Copyright © 2016 The Authors.

    Even in times of globalised markets, the German lignite industry retains its local and regional roots. Viewed against this background, the relationship between lignite industry and regional actors, and the interactions between the two play a major role in the perspectives for this branch of Germany's energy sector. Today, the links between the lignite industry and regional bodies are those of a partnership at eye-level. This type of relationship between the industry and regional actors has led to new forms and methods of cooperation at various levels. This is particularly evident in the efforts to re-shape the regional structure, develop the structure of townships and strengthen the economic structure with lignite playing an important role and new partners which are gaining in importance.

    This study was undertaken in an attempt to identify the level of birth and infant death in the KHDI demonstration areas. The objectives of this study were to collect available information on birth and infant death in the KHDI demonstration areas, and estimate actual levels of birth and infant mortality in these areas. Within these areas, events of birth and death are continuously recorded by the field health workers, such as the Family Folder, maternal health service card, and the infant-child health service card. Study areas included all the KHDI demonstration areas (Hongchon, Okgu, Gunee). However, 2 myons in the Okgu area were excluded from the study areas since there was no community health practitioner assigned there. The data were collected by 24 community health practitioners and 80 community health aides in the 3 demonstration areas, according to the survey format. These health workers examined and searched existing records. After filling out the survey questionnaires, these health workers made contact with village health workers, "Li" chiefs, mother's club chiefs, or Saemaul leaders at the village level in order that they might gather additional information on possible items which were omitted. Afterwards, health workers made home visits to selected households which were known to have had births or deaths during the 1 year period between January-December 1979. A review of the activities of the health workers during this study indicated that professional survey workers were needed. In addition, 8 surveyors were employed and trained by KHDI to strengthen field survey efforts; they were dispatched to Hongchon and Okgu for 17 days. A total number of 3302 live births and 120 infant deaths were recorded during 1979. All data collected were tabulated by manual counting in the KHDI office. Infant mortality was estimated to be 36.34/1000 births in the demonstration areas during 1979 (rate in Hongchon Gun was 34.5, 31.0 in Okgu Gun, and 46.2 in Gunee Gun). (author's)

    The ''AEC-Maryland Regional Siting Factors Study'' examines the process of siting in a regional context. It is developing an analysis method to delineate candidate areas for siting of several power plant technology packages, including both fossil-fueled and nuclear options. Tools that are being used include simulation modeling, economic and demographic forecasting, spatial analysis, and computer graphics and numerical manipulation. The approach will describe the trade-offs incurred if a power plant is located in one candidate area rather than in another. In FY 1974, a suitability analysis method was developed which uses engineering and environmental parameters to define a level of environmental cost incurred if a segment of land is used to site a specific technology package.

    2008-10-01

    This report discusses the main aspects of the ductile and brittle deformational evolution of the Laxemar-Simpevarp area.

    This report discusses the main aspects of the ductile and brittle deformational evolution of the Laxemar-Simpevarp area. Based on the interpretation of existing potential field geophysical data, it is suggested that the structural ductile grain of the region is controlled by large, c. EW trending shear zones with an overall sinistral strike-slip kinematics. The Oskarshamn Shear Zone (OSZ) and the Mederhult lineament are two examples of these shear zones and it is proposed that the ductile lineaments mapped in Laxemar-Simpevarp are genetically linked to shearing accommodated by these shear zones.

    Termite mounds are abundant components of Tummalapalle area of uranium mineralization of Cuddapah District of Andhra Pradesh, India. The systematic research has been carried out on the application of termite mound sampling to mineral exploration in this region. The distribution of chemical elements Cu, Pb, Zn, Ni, Co, Cr, Li, Rb, Sr, Ba, and U were studied both in termite soils and adjacent surface soils. Uranium accumulations were noticed in seven termite mounds ranging from 10 to 36 ppm. A biogeochemical parameter called "Biological Absorption Coefficient" of the termite mounds indicated the termite affected soils contained huge amounts of chemical elements than the adjacent soils.

    The goal is to achieve a model of radar sea reflection with improved fidelity that is amenable to practical implementation. The geometry of reflection from a wavy surface is formulated. The sea surface is divided into two components: the smooth `chop' consisting of the longer wavelengths, and the `roughness' of the short wavelengths. Ordinary geometric reflection from the chop surface is broadened by the roughness. This same representation serves both for forward scatter and backscatter (sea clutter). The `Road-to-Happiness' approximation, in which the mean sea surface is assumed cylindrical, simplifies the reflection geometry for low-elevation targets. The effect of surface roughness is assumed to make the sea reflection coefficient depending on the `Deviation Angle' between the specular and the scattering directions. The `specular' direction is that into which energy would be reflected by a perfectly smooth facet. Assuming that the ocean waves are linear and random allows use of Gaussian statistics, greatly simplifying the formulation by allowing representation of the sea chop by three parameters. An approximation of `low waves' and retention of the sea-chop slope components only through second order provides further simplification. The simplifying assumptions make it possible to take the predicted 2D ocean wave spectrum into account in the calculation of sea-surface radar reflectivity, to provide algorithms for support of an operational system for dealing with target tracking in the presence of multipath. The product will be of use in simulated studies to evaluate different trade-offs in alternative tracking schemes, and will form the basis of a tactical system for ship defense against low flyers.

In the period 2006-2011, were made 1080 cervical samples of women aged 18-65 years for HPV identification and genotyping. Detection of the virus was performed by Multiplex-PCR System (Seegene,Arrow and typing with INNO-LiPA HPV Genotyping Extra test (Innogenetics. Out of the 1080 tested samples, 330 (30.6% samples were positive for HPV DNA. The most frequently occurring High Risk (HR-HPV genotype in single infections was HPV16 (16.6%, followed by HPV51 (10.7%, in multiple infections HPV16 (15.7% and 31 (14.6%. The prevalence of infection, correlated with age of patients studied, is greater in the group aged 26-30 years (42.5%. HR-HPV were detected in different percent in patients with Pap test scores: 22.5% in normal Pap smear (20% HPV16, 14.5% ASCUS (47.6% HPV16, 24% LSIL (20% HPV16, 79.3% HSIL (72.7% HPV16; 9.1% HPV18 detected only in this type of cellular alteration. The high prevalence of HR-HPV in patients with ASCUS or normal Pap test, suggesting the real advantage of HPV screening test, more sensitive in selecting the actual population at risk. Based on the findings of our epidemiological study, HR-HPV screening and HPV genotyping test should be strongly advised also to the vaccinated population for the high incidence of genotypes which are not included in vaccines (67%.

    Full Text Available This study presents a checklist of Dipterans and Coleopterans accountable for carrion decay in the Po Valley (Italy, a contribution to the Forensic Entomology knowledge in Italy. Insects colonizing two pig carcasses in an agricultural area in Mezzani municipality (Parma, Northern Italy were sampled by pitfall traps and original Malaise-like traps, which allowed the sampling of a very relevant number of flying insects. A checklist of 57 taxa was obtained, of which 26 were considered of forensic importance. For the latter the arrival time of adult specimens on the carcasses was recorded, as an important parameter in minimum post mortem interval estimation. Dipterans (6141 specimens were the most common insects; the fastest specimens to detect and colonize the carcass belonged to the Calliphoridae family, while Fanniidae and Muscidae infested the carrion until completion of the skeletal stage. Coleopterans appeared later (308 adult specimens and 114 larvae were captured. Staphylinidae, Dermestidae, and Histeridae were the most common coleopterans sampled in this study.

    Full Text Available Background and Objective. Modern neuroimaging developments have demonstrated that cognitive functions correlate with brain networks rather than specific areas. The purpose of this paper was to analyze the connectivity of Broca's area based on language tasks. Methods. A connectivity modeling study was performed by pooling data of Broca's activation in language tasks. Fifty-seven papers that included 883 subjects in 84 experiments were analyzed. Analysis of Likelihood Estimates of pooled data was utilized to generate the map; thresholds at p < 0.01 were corrected for multiple comparisons and false discovery rate. Resulting images were co-registered into MNI standard space. Results. A network consisting of 16 clusters of activation was obtained. Main clusters were located in the frontal operculum, left posterior temporal region, supplementary motor area, and the parietal lobe. Less common clusters were seen in the sub-cortical structures including the left thalamus, left putamen, secondary visual areas and the right cerebellum. Conclusions. BA44-related networks involved in language processing were demonstrated utilizing a pooling-data connectivity study. Significance, interpretation and limitations of the results are discussed.

    This study is a part of a larger Finnish project financed by the Ministry of Transport and Communications concerned with evaluating the impacts of new integrated fare and ticket policies. The objective of the policy is to encourage a modal shift from cars to public transport, thereby reducing energy use and the harmful environmental effects of transport. The regional bus card systems (RBC) provide the opportunity to purchase a monthly ticket, at a substantial discount of normal fares, which is valid on all buses in an area covering a city centre and the smaller independent communities surrounding. RBC systems are subsidized by both Local Authorities and the state government and are currently operating in over ten urban areas in Finland. The objectives of this research project are: (1) to estimate the fare elasticities of the demand of bus services and the price elasticities of RBC demand, (2) to evaluate the effectiveness of the adopted subsidizing policy and (3) to assess the consequences of the fares policy on energy use in transport. This paper deals specifically with the latter two issues. (EG)

    We describe and analize the activities we carried out in a surgery from a preventive dentistry unit. Longitudinal descriptive study from 1993 since 1994. Health Area 8 from the Valencian Autonomous Region. Children from 3 to 14 year-old attendant to the preventive dentistry unit's surgery (2.497). We visited 5.012 children. The highest percentage of population corresponded to the zona 4, where began at first the preventive service. The activities distribution was as follow: oral explorations and plaque control (100%), fluoride topic aplication (90.38%), diet control (36.81%), pit and fisure sealants (6.46%), profilaxis (8.71%), radiological diagnosis (6.46%), dental emergencies (2.17%). The users origin was: 38.88% school oral explorations made over 6- and 10-year-old children; 63.71% from self-request; and 16.45% sent by other health professionals. 41.42% were continuated visits. Demand of preventive dental services is very high in our health area, although incorporation of therapeutic techniques is wished by the population. This demand increase as well as the surgery is closer to the user. People from big cities are stubborn using these services from smallest villages, even having transport facilities. Children start coming to the consults between 5-6 year-old, keeping an acceptable control until 12 approximately.

    objective of this study is to support the development of a preliminary Site Description of the Simpevarp area on a regional-scale based on the available data of August 2004 (Data Freeze S1.2) and the previous Site Description. A more specific objective of this study is to assess the role of known and unknown hydrogeological conditions for the present-day distribution of saline groundwater in the Simpevarp area on a regional-scale. An improved understanding of the paleo-hydrogeology is necessary in order to gain credibility for the Site Description in general and the hydrogeological description in particular. This is to serve as a basis for describing the present hydrogeological conditions on a local-scale as well as predictions of future hydrogeological conditions. Other key objectives were to identify the model domain required to simulate regional flow and solute transport at the Simpevarp area and to incorporate a new geological model of the deformation zones produced for Version S1.2.Another difference with Version S1.1 is the increased effort invested in conditioning the hydrogeological property models to the fracture boremap and hydraulic data. A new methodology was developed for interpreting the discrete fracture network (DFN) by integrating the geological description of the DFN (GeoDFN) with the hydraulic test data from Posiva Flow-Log and Pipe-String System double-packer techniques to produce a conditioned Hydro-DFN model. This was done in a systematic way that addressed uncertainties associated with the assumptions made in interpreting the data, such as the relationship between fracture transmissivity and length. Consistent hydraulic data was only available for three boreholes, and therefore only relatively simplistic models were proposed as there isn't sufficient data to justify extrapolating the DFN away from the boreholes based on rock domain, for example. Significantly, a far greater quantity of hydro-geochemical data was available for calibration in the

    The past application of nuclear technology has brought about free emission of numerous Due to the military application of the depleted uranium (DU) in our country, the problem of its radioactivity and hemo toxicity if actualized. Likewise every heavy metal, its is highly toxic and, in addition to it, also radioactive: Interaction of the water-soluble uranium forms with soil is an important effect. In this way, it penetrates into food chain and endangers human health. The study was aimed at determining possible karyotype genotoxic effects in individuals from the regions close to the contaminated areas. Biological dosimetry was performed using modified Moorthead's micromethod. Our studies included the targeted group of 29 patients from the affected regions. The subjects were averagely aged 39.5±2.8 years. Average age of the control group (k), unexposed to the effects of the known genotoxic agents comprising 22 individuals was 28.3±1.2 years. The presented data evidenced that increased incidence of the chromosomal aberrations was found in 6 subjects,accounting for 20.6%. Dicentric type changes were evidence, as well ring chromosomes and eccentric fragments, which are, at the same time the most frequent aberrations. The changes are considered reparable aberrations accounting for 2-3% in metaphases of the unexposed individuals. Statistical data processing evidenced significant difference (p<0.005) between structural chromosomal aberrations in the studied and control groups, as well as in the number of chromatid aberrations (p<0.05).Based on the obtained data it may be concluded that human karyotype changes were present in the studied group, resulting from interaction of ionizing irradiation and other genotoxic agents, with possibility of potent synergistic effects. It is necessary to stress the importance of further monitoring and control of the general population health, particularly due to possible late genetic effects that may affect future generations.

    Inhalation of radon and its daughter products is the major contributor to the total exposure of the population to natural radiation. The present study has measured radon gas concentration in some Adobe houses and the soil radon gas around these houses in the Kassena Nankana Area of the Upper East Region by using passive radon indoor dosimeter containing solid-state nuclear track detector (SSNTD) commercially known as LR - 115 (type II, pelliculable). Fifty (50) indoor radon dosimeters were placed in the various Adobe houses in the study area. Additionally, thirty (30) dosimeters were placed in the soil around some of the houses at a depth of 75 cm. Soil radon dosimeters were retrieved after two (2) weeks while the indoor radon dosimeters were retrieved after 78 to 82 days. The detectors were then chemically etched. The digital laser optic system and the spark counter coupled with microfiche reader were used in counting both the indoor and soil detectors respectively. Indoor radon concentration in the study area range from 35.28 Bq/m 3 to 244.22 Bq/m 3 . An active dosimeter known as the radon scout plus which gives instantaneous readings between 1 to 3 hours was also used in nineteen of the adobe houses in the study area and a total average radon concentration of 56.90 Bq/m3 was obtained. The soil radon concentration was also found to range from 2.12 kBq/m 3 to 15.03 kBq/m 3 . A good correlation was found to exist between the soil radon concentration and that of the indoor radon concentration with a correlation coefficient of about 0.61. The mean radon emanation coefficient of some fifteen (15) soil samples monitored was 0.46. The average annual effective dose was estimated to be about 1.66 mSv/y and that of the average annual effective dose using the equilibrium equivalent factor (F) was 1.00 mSv/y

The resuspension of surface soil did not contribute much to the spreading of the radionuclide in Goiania, but can lead to the local contamination of vegetables, equipment, structures and other environmental surfaces. The mechanism also presented a seasonal effect. The soil is an important medium for the uptake of {sup 137} Cs by small domestic animals. The street dust sampling is a suitable method to assess the dispersion of {sup 137} Cs in urban areas. After 10 years, the radionuclide activity concentration is restricted only to the initially impacted area an it is decreasing with time. (author) 9 refs., 2 figs, 2 tabs.

    The Jonico-Salentino project (PJS) is a multidisciplinary study funded by Apulia Region (Det. N. 188_RU - 10/11/2015) aiming to assess health risk of people living in the cities of Lecce, Brindisi and Taranto. Citizens are exposed to emissions from industrial sources, biomass burning, vehicular, naval and air traffic, as well as from natural radioactive sources (radon). In this context, this work presents some preliminary results obtained by the Unit of University of Salento (Lecce) during an experimental campaign carried out in the study areas. The campaign is devoted to (i) sample particulate matter (PM), (ii) measure micro-meteorological variables and (iii) evaluate exposure levels of residents to main pollutants. Specifically, PM is sampled using a low volume sampler, while meteorological variables (wind speed components and direction temperature, relative humidity, precipitation and global solar radiation) are measured by advanced instrumentation such as ultrasonic anemometers which allows for the estimation of turbulence fluxes. The early effects of exposure to air pollutants is evaluated by the frequency of micronucleus (a biomarker of DNA damage) in exfoliated buccal cells collected using a soft-bristled toothbrush from oral mucosa of primary school children enrolled in the study. PM concentration data collected during the campaign are characterised from a chemical and morphological point of view; the analysis of different groups of particles allows identifying different natural and anthropogenic emission sources. This is done in conjunction to the investigation of the influence of local meteorology to elucidate the contribution of specific types of sources on final concentration levels. Finally, all data are used to assess the health risk of people living in the study areas as consequence of exposure to airborne pollutants.

    The goal of this study is to analyze the floristic patterns and the structure of disturbed and undisturbed upland forests, in Permanent Preservation Areas (PPAs) along the Moju river, in the Brazilian state of Pará. Trees with a diameter equal to or larger than 10cm at 1.30m from the ground (DBH) ≥10cm were analyzed for the upper stratum. For the middle stratum, individuals with DBH between 4.99 and 9.99cm were sampled. Forty-five families and 221 species were found in disturbed forests, and 43 families and 208 species in undisturbed forests. Floristic similarity was high between strata and between forest types, with values above 50%. Similarity was highest between middle strata. The most species-abundant families in undisturbed forests were Fabaceae, Sapotaceae, Chrysobalanaceae and Myrtaceae; the species with the highest density there were Eschweilera grandiflora, Licania sclerophylla and Zygia cauliflora. In disturbed forests, the dominant families were Fabaceae, Sapotaceae, Lecythidaceae and Melastomataceae. The Shannon-Wiener diversity index was 3.21 for undisturbed forests and 2.85 for disturbed forests. Non-metric multidimensional scaling (MDS) analysis did not group the forests by their floristic composition in both upper and middle strata. Overall, the PPA forests along the Moju river, even if disturbed, did not show major floristic changes but substantially change their structural characteristics.

    Burion, Steve; Funk, Tobias; Speidel, Michael A.

    2013-01-01

    Purpose: Reduction of radiation dose in x-ray imaging has been recognized as a high priority in the medical community. Here the authors show that a regional adaptive exposure method can reduce dose-area product (DAP) in x-ray fluoroscopy. The authors' method is particularly geared toward providing dose savings for the pediatric population. Methods: The scanning beam digital x-ray system uses a large-area x-ray source with 8000 focal spots in combination with a small photon-counting detector. An imaging frame is obtained by acquiring and reconstructing up to 8000 detector images, each viewing only a small portion of the patient. Regional adaptive exposure was implemented by varying the exposure of the detector images depending on the local opacity of the object. A family of phantoms ranging in size from infant to obese adult was imaged in anteroposterior view with and without adaptive exposure. The DAP delivered to each phantom was measured in each case, and noise performance was compared by generating noise arrays to represent regional noise in the images. These noise arrays were generated by dividing the image into regions of about 6 mm 2 , calculating the relative noise in each region, and placing the relative noise value of each region in a one-dimensional array (noise array) sorted from highest to lowest. Dose-area product savings were calculated as the difference between the ratio of DAP with adaptive exposure to DAP without adaptive exposure. The authors modified this value by a correction factor that matches the noise arrays where relative noise is the highest to report a final dose-area product savings. Results: The average dose-area product saving across the phantom family was (42 ± 8)% with the highest dose-area product saving in the child-sized phantom (50%) and the lowest in the phantom mimicking an obese adult (23%). Conclusions: Phantom measurements indicate that a regional adaptive exposure method can produce large DAP savings without compromising

    A mineral survey conducted within the Centennial Mountains Wilderness study area in Montana and Idaho showed large areas of probable and substantiated resource potential for phosphate. Byproducts that may be derived from processing the phosphate include vanadium, chromium, uranium, silver, fluorine, and the rare earths, lanthanum and yttrium. Results of a geochemical sampling program suggest that there is little promise for the occurrence of base and precious metals in the area. Although the area contains other nonmetallic deposits, such as coal, building stone, and pumiceous ash they are not considered as mineral resources. There is a probable resource potential for oil and gas and significant amounts may underlie the area around the Peet Creek and Odell Creek anticlines.

    . Soil and grass samples were collected regularly and analysed for the concentrations of I, Cs and Sr isotopes to evaluate the soil to grass transfer factors. The milk samples from the adopted cows were collected daily and analyzed for the radioactive and stable elements concentrations to evaluate the grass to cow transfer coefficients. For comparative studies, soil and grass samples were collected from different dominant grassing areas around Kaiga region and cow milk samples were collected from local farmers. It should be noted that the transfer coefficients obtained for equilibrium conditions may not be totally applicable for emergency situation. Studies aimed at evaluating transfer coefficients of iodine, caesium and strontium for emergency situations are sparse. Hence, we have carried out spike experiments using stable iodine, caesium and strontium isotopes to generate data on transfer coefficients for emergency situations. In order to estimate the ingestion dose, accurate data on dietary habits of the population was necessary and this was collected through a well planned demographic survey. Using the data on dietary habits and the transfer coefficient values, the ingestion dose to the population (child and adult) due to 131 I, 137 Cs and 90 Sr was also estimated. Details of all the above studies and a detailed account of the facilities available in the Radioecology Laboratory of Mangalore University which is serving as regional facility for researchers from other institutions, are also presented in this talk.

    The numerical modeling of groundwater flow is an important aspect of hydrogeological assessment in siting of a high level radioactive waste disposal repository. Hydrogeological conceptual model is the basic and premise of numerical modeling of groundwater flow. Based on the hydrogeological analysis of candidate Beishan area, surface water system was created by using DEM data and the modeling area is determined. Three-dimensional hydrogeological structure model was created through GMS software. On the basis of analysis and description of boundary condition, flow field, groundwater budget and hydrogeological parameters, hydrogeological conceptual model was set up for the Beishan area.

    A high natural radiation zone is investigated for the first time in a geothermal region of Eastern Ghats Mobile Belt (EGMB) of Orissa state in India. The surrounding area comprises a geothermal region which has surveyed using a portable pulsed Geiger-Muller counter. On the basis of findings of GM counter, an area was marked as a high radiation zone. Soil and rock samples collected from the high radiation zone were analyzed by γ-ray spectrometry (GRS) using NaI(Tl) detector. The radioactivity is found to be contributed mainly by thorium. Concentration of thorium is reported to be very high compared to their normal abundance in crustal rocks. Further, concentrations of 238 U and 40 K are also high compared to normal abundance in crustal rocks but their magnitude is comparatively less than that of thorium. The average concentrations of 238 U (i.e. U(β-γ)), 232 Th and 40 K are found to be 33, 459ppm and 3%, respectively, in soils and 312, 1723ppm and 5%, respectively, in the granitic rocks. Maximum concentrations of 238 U, 232 Th and 40 K are found to be 95, 1194ppm and 4%, respectively, in soils and 1434, 10,590ppm and 8%, respectively, in the granitic rocks. Radioactive element emits various energies in its decay chain. High energies are utilized to estimate the concentration of actual 238 U, 232 Th and 40 K using a NaI(Tl) detector, however, low energies are used for the same in an HPGe detector. Some of the rock samples (eight in number) were also analyzed using HPGe detector for studying the behavior of low energies emitted in the decay series of uranium and thorium. The absorbed gamma dose rate in air and external annual dose rate of the high radiation zone are calculated to be 2431nGy/h and 3.0mSv/y, respectively. It is approximately 10 times greater than the dose rates obtained outside the high radiation zone. The high concentration of uranium and thorium may be one of the possible heat sources together with the normal geothermal gradient for hot springs

    Full Text Available CONTEXT: The drawing up of adequate Public Health action planning to address the true needs of the population would increase the chances of effectiveness and decrease unnecessary expenses. OBJECTIVE: To identify homogeneous regions in the UNIFESP/EPM healthcare center (HCC coverage area based on sociodemographic indicators and to relate them to causes of deaths in 1995. DESIGN: Secondary data analysis. SETTING: HCC coverage area; primary care. SAMPLE: Sociodemographic indicators were obtained from special tabulations of the Demographic Census of 1991. MAIN MEASURES: Proportion of children and elderly in the population; family providers’ education level (maximum: >15 years, minimum: 20 minimum wages, minimum: <1 minimum wage; proportional mortality distribution. RESULTS: The maximum income permitted the construction of four homogeneous regions, according to income ranking. Although the proportion of children and of elderly did not vary significantly among the regions, minimum income and education showed a statistically significant (p<0.05 difference between the first region (least affluent and the others. A clear trend of increasing maximum education was observed across the regions. Mortality also differed in the first region, with deaths generated by possibly preventable infections. CONCLUSION: The inequalities observed may contribute to primary health prevention.

    Full Text Available Little is known about sexual risks and associated factors about female youths in semi-urban areas of Ethiopia. This study aimed to describe the nature and magnitude of risky sexual behaviors, and the socio-demographic and behavioral determinants among female youths in Tiss Abay, a semi-urban area on the outskirts of Bahir Dar City of the Amhara Region in northern Ethiopia.A cross-sectional census type study was conducted among female youths who were unmarried and aged 15-29 years in September 2011.711 female youths participated in the study, with the mean age of initiation of sex of 78.6% being16.73±2.53 years. Only 52(9.3% used condom during the first sex. Within the last 12 months, 509(71.6% had sexual intercourse and 278(54.6% had two or more sex partners, and 316(62.1% did not use condom during their last sex. Sex under the influence of substances was reported by 350(68.8%, and a third of the recent sexes were against the will of participants. One or more risky sexual practices were reported by 503(70.3% participants, including: multiple sexual partnerships, inconsistently using or not using condoms, sex under the influence of alcohol and/or sex immediately after watching pornography. Age group, current marital status, drinking homemade alcohol, chewing 'khat', watching pornography and using any form of stimulant substances were the predictors of risky sexual behavior. Watching pornography before sex and sex for transaction were the predicators of not using condom during most recent sex.Risky sexual behaviors were very common among the female youths in Tiss Abay. Initiation of context-based interventions, such as raising awareness about the risks, safer sex practices, condom promotion and integration of gender issues in the programs are recommended.
