  2. Health assessment for O'Connor Company site, Augusta, Kennebec County, Maine, Region 1. CERCLIS No. MED980731475. Preliminary report


    The F. O'Connor Site (FOC) is listed by the U.S. Environmental Protection Agency (EPA) on the National Priorities List. The 28-acre site is located in Augusta (Kennebec County), Maine. FOC recycled capacitors, transformers, and scrap metal for about 20 years. Waste oil from these operations was disposed of on-site or burned. Preliminary on-site soil sampling results have identified PCB's (ND to 200,000 ppm), various PAH's (ND to 23 ppm), and various metals such as lead (62 to 3,210 ppm), nickel (18 to 29 ppm), chromium (28 to 34 ppm), arsenic (8 to 13 ppm), and mercury (ND to 3 ppm). On-site groundwater sampling results detected 1,4-dichlorobenzene (ND to 28 ppb) and PCB's (ND to 72 ppb). Potential environmental pathways include those related to contaminated groundwater, surface water, soils and sediment, and volatilization of contaminants in ambient air. In addition, bioaccumulation of contaminants in fish, water fowl, livestock, and commercial agricultural products may be another environmental pathway. Based on available information, this site is considered to be of potential public health concern because of the risk to human health caused by the likelihood of human exposure to hazardous substances. Area residents may be exposed through direct contact with and ingestion of contaminated off-site soil and sediment. An additional exposure pathway may exist through the ingestion of fish, waterfowl, and other aquatic organisms that bioaccumulate site-related contaminants.

  5. Arsenic evolution in fractured bedrock wells in central Maine, USA

    Yang, Q.; Zheng, Y.; Culbertson, C.; Schalk, C.; Nielsen, M. G.; Marvinney, R.


    Elevated arsenic concentration in fractured bedrock wells has emerged as an important and challenging health problem, especially in rural areas without public water supply and mandatory monitoring of private wells. This has posed risks of skin, bladder, prostate diseases and cancers to private well users. In central Maine, including the study site, 31% of bedrock wells in meta-sedimentary formations have been reported of elevated arsenic concentrations of > 10 µg/L. Geophysical logging and fracture specific water sampling in high arsenic wells have been conducted to understand how water flowing through the aquifers enters the boreholes and how arsenic evolves in the fracture bedrock wells. Two domestic wells in Manchester, Maine, located 50 meter apart with 38 µg/L and 73 µg/L of arsenic in unfiltered water, were investigated to characterize fractures by geophysical logging and to determine flow rates by pumping test. Water samples, representing the bore hole and the fractures, were collected and analyzed for arsenic under ambient and pumping conditions. Transmissivity of the fractures was estimated at 0.23-10.6 m2/day. Water with high dissolved arsenic was supplied primarily by high yielding fractures near the bottom of the borehole. Dissolved arsenic concentrations in borehole water increased as fracture water with high arsenic was replacing borehole water with initially low dissolved arsenic in response to pumping. The precipitation of iron particulates enriched in arsenic was common during and after pumping. Laboratory experiment on well water samples over a period of 16 days suggested that in the borehole arsenic was mainly settled with iron enriched particles, likely amorphous ferric oxyhydroxides, with possibly minor adsorption on the iron minerals. Another bedrock well in Litchfield, Maine, with 478 µg/L of arsenic in the unfiltered well water, is being investigated to quantify and reconstruct of the groundwater flow under ambient and pumping conditions

    It seems that the ancient Roman towns were oriented with the sunrise. Here I propose a discussion on the orientation of Torino, the Julia Augusta Taurinorum, which has the ancient Roman structure perfectly preserved. According to this ancient ritual, we can use the sunrise amplitude to determine the Turin's birthday. The use of the hour angle is also proposed, in this case the day of the foundation of Turin could be the winter solstice.

  13. Canada lynx Lynx canadensis habitat and forest succession in northern Maine, USA

    Hoving, C.L.; Harrison, D.J.; Krohn, W.B.; Jakubas, W.J.; McCollough, M.A.


    The contiguous United States population of Canada lynx Lynx canadensis was listed as threatened in 2000. The long-term viability of lynx populations at the southern edge of their geographic range has been hypothesized to be dependent on old growth forests; however, lynx are a specialist predator on snowshoe hare Lepus americanus, a species associated with early-successional forests. To quantify the effects of succession and forest management on landscape-scale (100 km2) patterns of habitat occupancy by lynx, we compared landscape attributes in northern Maine, USA, where lynx had been detected on snow track surveys to landscape attributes where surveys had been conducted, but lynx tracks had not been detected. Models were constructed a priori and compared using logistic regression and Akaike's Information Criterion (AIC), which quantitatively balances data fit and parsimony. In the models with the lowest (i.e. best) AIC, lynx were more likely to occur in landscapes with much regenerating forest, and less likely to occur in landscapes with much recent clearcut, partial harvest and forested wetland. Lynx were not associated positively or negatively with mature coniferous forest. A probabilistic map of the model indicated a patchy distribution of lynx habitat in northern Maine. According to an additional survey of the study area for lynx tracks during the winter of 2003, the model correctly classified 63.5% of the lynx occurrences and absences. Lynx were more closely associated with young forests than mature forests; however, old-growth forests were functionally absent from the landscape. Lynx habitat could be reduced in northern Maine, given recent trends in forest management practices. Harvest strategies have shifted from clearcutting to partial harvesting. If this trend continues, future landscapes will shift away from extensive regenerating forests and toward landscapes dominated by pole-sized and larger stands. Because Maine presently supports the only verified

  15. Agent-Based Modeling of Harvest Decisions by Small Scale Forest Landowners in Maine, USA

    Jessica E. Leahy


    Full Text Available Small-scale forests are an excellent example of coupled social-ecological systems, which involve human and biophysical subsystems with complex two-way feedback interactions. The multifaceted nature of landowner decisions drives a significant need to better understand decision-making processes, reactions to policy, and combined impacts on ecosystems in a comprehensive manner. Small-scale forests require an integrated approach to modeling the social and biophysical components comprehensively. Agent-based modeling involves modeling individualistic behavior and interpreting patterns that emerge. The interaction between agents and their environments makes this a valuable tool to assess repeated decisions of individual landowners responding to changing environmental conditions. Agent-based models can be used to determine potential ecological, economic, and social outcomes of landowner decisions and reactions to changing conditions. A forest landowner agent-based model experiment was developed to model timber harvesting in Maine, USA. We present baseline simulation results and compare the effect of a social change (an increased tax rate and a biophysical change (a pest outbreak resulting in increased tree mortality on the system. These three scenarios were analyzed using ANOVA and MANOVA tests on harvested hectares and landowner goal scores to assess landowner behavior and priorities by action. We conclude by reviewing implications for future modeling efforts.

  16. Automated feature extraction and spatial organization of seafloor pockmarks, Belfast Bay, Maine, USA

    Andrews, B.D.; Brothers, L.L.; Barnhardt, W.A.


    Seafloor pockmarks occur worldwide and may represent millions of m3 of continental shelf erosion, but few numerical analyses of their morphology and spatial distribution of pockmarks exist. We introduce a quantitative definition of pockmark morphology and, based on this definition, propose a three-step geomorphometric method to identify and extract pockmarks from high-resolution swath bathymetry. We apply this GIS-implemented approach to 25km2 of bathymetry collected in the Belfast Bay, Maine USA pockmark field. Our model extracted 1767 pockmarks and found a linear pockmark depth-to-diameter ratio for pockmarks field-wide. Mean pockmark depth is 7.6m and mean diameter is 84.8m. Pockmark distribution is non-random, and nearly half of the field's pockmarks occur in chains. The most prominent chains are oriented semi-normal to the steepest gradient in Holocene sediment thickness. A descriptive model yields field-wide spatial statistics indicating that pockmarks are distributed in non-random clusters. Results enable quantitative comparison of pockmarks in fields worldwide as well as similar concave features, such as impact craters, dolines, or salt pools. ?? 2010.

  17. Streamflow variability and hydroclimatic change at the Bear Brook Watershed in Maine (BBWM), USA.

    Kim, Jong-Suk; Jain, Shaleen; Norton, Stephen A


    Seasonal variations in streamflow and the associated hydrologic extremes impart significant temporal structure to watershed-scale chemical fluxes. Consequently, a careful characterization of the episodic-to-seasonal and longer-term streamflow variations is a first step toward developing a comprehensive view of the temporal dynamics of watershed processes in a changing climate. Here we analyze a nearly two-decade-long streamflow record for the East Bear subwatershed within the Bear Brook Watershed in Maine (BBWM) (USA) to understand the envelope of streamflow variability by season, with a particular focus on the high flow events that have a disproportionately large impact on the biogeochemical processes and fluxes. Interannual and longer-term variations in a number of derived statistical metrics of hydrologic variability are examined. Our analysis shows substantial interannual and longer-term variability in seasonal flow volumes and peak flows. Furthermore, a long, unimpaired streamflow record for the Narraguagus River (a proximate watershed to the BBWM) is examined with a view to understand the relative coherence in hydrologic variability, as well as quantifying the decadal and longer-term hydrologic variations in this region. We find that the streamflow variability in the two watersheds shows similarity in all seasons. A moving window analysis to assess the changing flood potential over time indicates upward trends in the recent decades. Spring season (March-May) flood estimates show a near-monotonic trend over the 1949-2008 record. Finally, empirical relationships between streamflow and large-scale atmospheric circulation patterns highlight the regional and global climatic drivers of hydrologic extremes in this region, including impacts from remnants of Atlantic hurricanes.

  18. Tracing mercury pathways in Augusta Bay (southern Italy) by total concentration and isotope determination

    The mercury (Hg) pollution of sediments is the main carrier of Hg for the biota and, subsequently, for the local fish consumers in Augusta Bay area (SE Sicily, Italy), a coastal marine system affected by relevant sewage from an important chlor-alkali factory. This relationship was revealed by the determination of Mass Dependent (MDF) and Mass Independent Fractionation (MIF) of Hg isotopes in sediment, fish and human hair samples. Sediments showed MDF but no MIF, while fish showed MIF, possibly due to photochemical reduction in the water column and depending on the feeding habitat of the species. Benthic and demersal fish exhibited MDF similar to that of sediments in which anthropogenic Hg was deposited, while pelagic organisms evidenced higher MDF and MIF due to photoreduction. Human hair showed high values of δ202Hg (offset of +2.2‰ with respect to the consumed fish) and Δ199Hg, both associated to fish consumption. - Highlights: • We report the Hg isotope ratios of sediments, fish and human hair in Augusta Bay. • Hg isotopes show mercury transfers from sediments to benthic and demersal fish. • MIF in fish appears to be driven by effect of photoreduction. • MIF in human hair is inherited by fish consumption. - The mercury (Hg) isotope composition of sediments, fish muscles and human hair has been investigated from the highly polluted Augusta Bay (SE Sicily, Italy)

Civic knowledge includes clear understanding of the government structure and the processes of law adoption. At this stage the main focus in the process of civic education is directed to the students’ knowledge and skills to analyze historical and political events in the country, to understand the directions of the state policy in the country. The main function of the civic knowledge is its stimulation of the civic activity.The essential part of civic education is the formation of the civic skills, which are dependent on many factors including home environment, active and responsible participation in political life of the society, general education. These skills are classified as interaction, control and influence.The next basic component of civic education – civic position – is connected with personal and social characteristics of a citizen, which are important for active participation under the conditions of constitutional democracy. Civic position is closely connected with conscious readiness of a person to take part in social activity, availability of the theoretical civic know-ledge and practical civic skills. Itshould be mentioned that civic knowledge, civic skills and civic position are interconnected.Practical implications of the results. The results of the research are applicable in the process of working out of the new technologies, methods and approaches in education to

  2. Social-Ecological Scale Mismatches and the Collapse of the Sea Urchin Fishery in Maine, USA

    Robert L. Vadas


    Full Text Available Scale mismatches result in incomplete or ambiguous feedback that impairs the ability to learn and adapt and, ultimately, to sustain natural resources. Our aim is to examine the sea urchin fishery in Maine, USA to better understand the multiscale, social, and biophysical conditions that are important for the design of institutions that might be able to sustain the resource. During the late 1980s and 1990s, the Maine sea urchin fishery was a classic gold rush fishery. In the beginning, the fishery was characterized by an abundant resource with little to no harvesting activity, followed by a period of rapid increase in landings and effort that led to a subsequent and persistent decline in the sea urchin population and a significant reduction in effort. We conducted semistructured interviews with scientists and experienced fishermen to understand the multiscale, social, and biophysical conditions that influence fishermen's harvesting strategies, and the implications of this for the design of institutions for successful resource management. The current co-management system includes an advisory body made up of industry members and scientists it also includes limited entry, and additional input control mechanisms. Many of these measures are implemented at a very broad scale; however, we find that the ecological conditions relevant to the sustainable processes occur at the scale of individual fishing sites or ledges, which is a much finer scale than current management. Therefore, the co-management system maintains an open access system and leaves few incentives for the development of sustainable harvesting strategies among fishermen. The clear suggestion is that the appropriate management system would be one that directly addresses the fine scale ecological and social dynamics within this fishery and gives fishermen property rights over individual ledges (for example, leases. After having briefly reviewed experiences in Canada and Chile, we found that

  10. Particle size distribution of main-channel-bed sediments along the upper Mississippi River, USA

    Remo, Jonathan; Heine, Ruben A.; Ickes, Brian


    In this study, we compared pre-lock-and-dam (ca. 1925) with a modern longitudinal survey of main-channel-bed sediments along a 740-km segment of the upper Mississippi River (UMR) between Davenport, IA, and Cairo, IL. This comparison was undertaken to gain a better understanding of how bed sediments are distributed longitudinally and to assess change since the completion of the UMR lock and dam navigation system and Missouri River dams (i.e., mid-twentieth century). The comparison of the historic and modern longitudinal bed sediment surveys showed similar bed sediment sizes and distributions along the study segment with the majority (> 90%) of bed sediment samples having a median diameter (D50) of fine to coarse sand. The fine tail (≤ D10) of the sediment size distributions was very fine to medium sand, and the coarse tail (≥ D90) of sediment-size distribution was coarse sand to gravel. Coarsest sediments in both surveys were found within or immediately downstream of bedrock-floored reaches. Statistical analysis revealed that the particle-size distributions between the survey samples were statistically identical, suggesting no overall difference in main-channel-bed sediment-size distribution between 1925 and present. This was a surprising result given the magnitude of river engineering undertaken along the study segment over the past ~ 90 years. The absence of substantial differences in main-channel-bed-sediment size suggests that flow competencies within the highly engineered navigation channel today are similar to conditions within the less-engineered historic channel.

  11. The geomorphic function and characteristics of large woody debris in low gradient rivers, coastal Maine, USA

    Magilligan, F. J.; Nislow, K. H.; Fisher, G. B.; Wright, J.; Mackey, G.; Laser, M.


    The role, function, and importance of large woody debris (LWD) in rivers depend strongly on environmental context and land use history. The coastal watersheds of central and northern Maine, northeastern U.S., are characterized by low gradients, moderate topography, and minimal influence of mass wasting processes, along with a history of intensive commercial timber harvest. In spite of the ecological importance of these rivers, which contain the last wild populations of Atlantic salmon ( Salmo salar) in the U.S., we know little about LWD distribution, dynamics, and function in these systems. We conducted a cross-basin analysis in seven coastal Maine watersheds, documenting the size, frequency, volume, position, and orientation of LWD, as well as the association between LWD, pool formation, and sediment storage. In conjunction with these LWD surveys, we conducted extensive riparian vegetation surveys. We observed very low LWD frequencies and volumes across the 60 km of rivers surveyed. Frequency of LWD ≥ 20 cm diameter ranged from 15-50 pieces km - 1 and wood volumes were commonly DBH. These results strongly reflect the legacy of intensive timber harvest and land clearing and suggest that the frequency and distribution of LWD may be considerably less than presettlement and/or future desired conditions.

  12. Soil chemical and physical properties at the Bear Brook Watershed in Maine, USA.

    SanClements, Michael D; Fernandez, Ivan J; Norton, Stephen A


    Acidic deposition leads to the acidification of waters and accelerated leaching and depletion of soil base cations. The Bear Brook Watershed in Maine has used whole-watershed chemical manipulations to study the effects of elevated N and S on forest ecosystem function on a decadal time scale. The objectives of this study were to define the chemical and physical characteristics of soils in both the reference and treated watersheds after 17 years of treatment and assess evidence of change in soil chemistry by comparing soil studies in 1998 and 2006. Results from 1998 confirmed depletion of soil base cation pools and decreased pH due to elevated N and S within the treated watershed. However, between 1998 and 2006, during a period of declining SO4(2-) deposition and continued whole-watershed experimental acidification on the treated watershed, there was little evidence of continued soil exchangeable base cation concentration depletion or recovery. The addition of a pulse of litterfall and accelerating mineralization from a severe ice storm in 1998 may have had significant effects on forest floor nutrient pools and cycling between 1998 and 2006. Our findings suggest that mineralization of additional litter inputs from the ice storm may have obscured temporal trends in soil chemistry. The physical data presented also demonstrate the importance of coarse fragments in the architecture of these soils. This study underscores the importance of long-term, quantitative soil monitoring in determining the trajectories of change in forest soils and ecosystem processes over time. PMID:20559716

  13. Using hydrologic measurements to investigate free phase gas ebullition in a Maine Peatland, USA

    C. E. Bon


    Full Text Available Northern Peatlands cover more than 350 million ha and are an important source of methane (CH4 and other biogenic gases contributing to climate change. Free phase gas (FPG accumulation and episodic release has recently been recognized as an important mechanism for biogenic gas flux from peatlands. It is likely that gas production and groundwater flow are interconnected in peatlands: groundwater flow influences gas production by regulating geochemical conditions and nutrient supply available for methanogenesis while FPG influences groundwater flow through a reduction in peat permeability and by creating excess pore water pressures. Water samples collected from three well sites at Caribou Bog, Maine, show substantial dissolved CH4 (5–16 mg L−1 in peat waters below 2 m depth and an increase in concentrations with depth. This suggests substantial production and storage of CH4 in deep peat that may be episodically released as FPG. Two minute increment pressure transducer data reveal approximately 5 cm fluctuations in hydraulic head from both deep and shallow peat that are believed to be indicative of FPG release. FPG release persists up to 24 h during decreasing atmospheric pressure and a rising water table. Preferential flow is seen towards an area of relatively lower hydraulic head associated with the esker and pool system. Increased CH4 concentrations are also found at the depth of the esker crest suggesting that the high permeability esker is acting as a conduit for groundwater flow, driving a downward transport of labile carbon, resulting in higher rates of CH4 production.

    We assessed changes in vegetative structure of 49 impoundments at Moosehorn National Wildlife Refuge (MNWR), Maine, USA, between the periods 1984-1985 to 2002 with a multivariate, adaptive approach that may be useful in a variety of wetland and other habitat management situations. We used Mahalanobis Distance (MD) analysis to classify the refuge?s wetlands as poor or good waterbird habitat based on five variables: percent emergent vegetation, percent shrub, percent open water, relative richness of vegetative types, and an interspersion juxtaposition index that measures adjacency of vegetation patches. Mahalanobis Distance is a multivariate statistic that examines whether a particular data point is an outlier or a member of a data cluster while accounting for correlations among inputs. For each wetland, we used MD analysis to quantify a distance from a reference condition defined a priori by habitat conditions measured in MNWR wetlands used by waterbirds. Twenty-five wetlands declined in quality between the two periods, whereas 23 wetlands improved. We identified specific wetland characteristics that may be modified to improve habitat conditions for waterbirds. The MD analysis seems ideal for instituting an adaptive wetland management approach because metrics can be easily added or removed, ranges of target habitat conditions can be defined by field-collected data, and the analysis can identify priorities for single or multiple management objectives.

  17. Tracing mercury pathways in Augusta Bay (southern Italy) by total concentration and isotope determination.

    Bonsignore, M; Tamburrino, S; Oliveri, E; Marchetti, A; Durante, C; Berni, A; Quinci, E; Sprovieri, M


    The mercury (Hg) pollution of sediments is the main carrier of Hg for the biota and, subsequently, for the local fish consumers in Augusta Bay area (SE Sicily, Italy), a coastal marine system affected by relevant sewage from an important chlor-alkali factory. This relationship was revealed by the determination of Mass Dependent (MDF) and Mass Independent Fractionation (MIF) of Hg isotopes in sediment, fish and human hair samples. Sediments showed MDF but no MIF, while fish showed MIF, possibly due to photochemical reduction in the water column and depending on the feeding habitat of the species. Benthic and demersal fish exhibited MDF similar to that of sediments in which anthropogenic Hg was deposited, while pelagic organisms evidenced higher MDF and MIF due to photoreduction. Human hair showed high values of δ(202)Hg (offset of +2.2‰ with respect to the consumed fish) and Δ(199)Hg, both associated to fish consumption. PMID:26074159


    The paired catchment study at the forested Bear Brook Watershed in Maine (BBWM) U.S.A. documents interactions among short- to long-term processes of acidification. In 1987-1989, runoff from the two catchments was nearly identical in quality and quantity. Ammonium sulfate has been...

  19. Steam injection pilot study in a contaminated fractured limestone (Maine, USA): Modeling and analysis of borehole radar reflection data

    Gregoire, C.; Lane, J.W., Jr.; Joesten, P.K.


    Steam-enhanced remediation (SER) has been successfully used to remove DNAPL and LNAPL contaminants in porous media. Between August and November 2002, SER was tested in fractured limestone at the former Loring Air Force Base, in Maine, USA. During the SER investigation, the U.S. Geological Survey conducted a series of borehole radar surveys to evaluate the effectiveness of radar methods for monitoring the movement of steam and heat through the fractured limestone. The data were collected before steam injection, 10 days after the beginning of injection, and at the end of injection. In this paper, reflection-mode borehole radar data from wells JBW-7816 and JBW-7817A are presented and discussed. Theoretical modeling was performed to predict the variation of fracture reflectivity owed to heating, to show displacement of water and to assess the effect of SER at the site. Analysis of the radar profile data indicates some variations resulting from heating (increase of continuity of reflectors, attenuation of deeper reflections) but no substantial variation of traveltimes. Spectral content analysis of several individual reflections surrounding the boreholes was used to investigate the replacement of water by steam in the fractures. Observed decrease in radar reflectivity was too small to be explained by a replacement of water by steam, except for two high-amplitude reflectors, which disappeared near the end of the injection; moreover, no change of polarity, consistent with steam replacing water, was observed. The decrease of amplitude was greater for reflectors near well JBW-7817A and is explained by a greater heating around this well.

  20. Response of white sucker (Catostomus commersoni) to pulp and paper mill effluent in the Androscoggin River, Maine, USA.

    Mower, Barry F; Munkittrick, Kelly R; McMaster, Mark E; Van Beneden, Rebecca J


    Adverse effects of pulp and paper mill effluent on fish populations have been well documented in many countries over the last two decades. Some of the initial studies were at mills with conventional chlorine bleaching and no secondary effluent treatment. Following installation of secondary treatment, changes in bleaching technology to elemental chlorine-free bleaching, and other process changes, adverse effects on fish were reduced or eliminated at some mills. Because no two mills are exactly alike, it is difficult to predict adverse impacts of any given mill on fish populations. In 1994, a study of female white sucker (Catostomus commersoni) in the Androscoggin River, Maine, USA, showed induction of mixed function oxidase, reductions in gonad size and plasma estradiol, and an increase in plasma testosterone in fish downstream of discharges from three large bleached kraft pulp and paper mills, and host community municipal sewage treatment plants (STP). After all three mills switched to elemental chlorine-free bleaching in the late 1990s, studies from 2001 to 2003 found that the pattern of reproductive impacts on white sucker populations measured in 1994 was not repeated. In addition, population estimates of white sucker from 2002 to 2003 using mark-recapture techniques found that densities and biomass were well within the range of those of a reference population, and of those reported in the literature for unimpacted populations. Detailed studies immediately above and below each mill/sewage treatment plant showed no evidence of reproductive effects. However, a clear pattern of eutrophication was noted, which increased cumulatively downstream below each mill/STP. PMID:20872897

    FK Saikot; Alam Khan; MF Hasan


    Objective: To evaluate the antimicrobial and cytotoxic activity of acetone extract of leaves ofAbroma augusta. Methods: Disc diffusion method was used to demonstrate antibacterial and antifungal activities. Cytotoxicity was determined against brine shrimp nauplii. In addition, minimum inhibitory concentration (MIC) was determined using serial dilution technique to determine antibacterial potency. Results: The extract showed significant antibacterial activities against three gram-positive (Bacillus subtilis, Bacillus megaterium and Staphylococcus aureus) and four gram-negative (Escherichia coli, Shigella dysenteriae, Shigella sonnei and Salmonella typhi) bacteria. The antifungal activity was found strong against five fungi (Aspergillus flavus, Aspergillus niger, Candida albicans, Rhizopus oryzae and Aspergillus fumigatus). In cytotoxicity determination, LC50 of the extract against brine shrimp nauplii was 7.06μg/ml. Conclusions: The Abroma leaves extract may be consider as a potent antimicrobial and cytotoxic agent for further advance research.

  5. Three-dimensional numerical simulations on wind- and tide-induced currents: The case of Augusta Harbour (Italy)

    De Marchis, Mauro; Freni, Gabriele; Napoli, Enrico


    The hydrodynamic circulation in the coastal area of the Augusta Bay (Italy), located in the eastern part of Sicily, is analysed. Due to the heavy contamination generated by the several chemical and petrochemical industries active in the zone, the harbour was declared a Contaminated Site of National Interest. To mitigate the risks connected with the industrial activities located near the harbour, it is important to analyse the hydrodynamic circulation in the coastal area. To perform such analysis, a parallel 3D numerical model is used to solve the Reynolds-averaged momentum and mass balance, employing the k-ε turbulence model for the Reynolds stresses. The numerical model is parallelized using the programing technology - Message Passing Interface (MPI) and applying the domain decomposition procedure. The Augusta Bay circulation is mainly due to the relative contribution of the wind force acting over the free surface and the tidal motion through the mouths. Due to the geometric complexity of the domain and the presence of several piers along the coast, a curvilinear boundary-fitted computational grid was used, where cells corresponding to land areas or to wharfs were excluded from the computation. Comparisons between numerical results and field measurements were performed. Three different simulations were performed to selectively isolate the effect of each force, wind and tide, acting in the considered domain. The current in the basin was successfully estimated on the basis of the numerical results, demonstrating the specific role of wind and tidal oscillation in the hydrodynamic circulation inside the harbour.

  6. The Penobscot River, Maine, USA: a Basin-Scale Approach to Balancing Power Generation and Ecosystem Restoration

    Laura Rose Day


    Full Text Available Although hydropower is a source of low-carbon energy, without careful consideration and management, dams have the potential to degrade river ecosystems and the goods and services they provide to society. Today, a broad range of hydropower interests and stakeholders are seeking approaches to hydropower development and operation that are more environmentally and socially sustainable. The Penobscot River Restoration Project ('the Project' illustrates that basin-scale approaches can provide a broader set of solutions for balancing energy and riverine environmental resources than can be achieved at the scale of individual projects. The Penobscot basin is the largest in Maine and historically supported culturally and economically significant populations of migratory fish. These migratory fish populations declined dramatically following the construction of a series of hydropower dams on the main stem river and major tributaries in the early 20th century. The Project, negotiated between a power company (PPL Corporation and a coalition including the Penobscot Indian Nation, resource agencies, and nongovernmental conservation organizations, features the removal of two main stem dams on the lower Penobscot and improved fish passage at the dams that remain. Because of various capacity and/or operational changes, power production will be increased at the remaining dams and total hydropower energy production from the basin will be maintained or increase slightly. The Project is expected to expand considerably the proportion of the basin accessible to migratory fish and contribute to significant increases in fish populations. The Project illustrates that a basin-scale approach can potentially yield more comprehensive solutions for sustainable hydropower than can be achieved at the project scale, and we recommend that such large-scale planning processes can improve the sustainability of both regulatory licensing of existing dams as well as the planning of

  7. Heavy metal contamination from historic mining in upland soil and estuarine sediments of Egypt Bay, Maine, USA

    Osher, L. J.; Leclerc, L.; Wiersma, G. B.; Hess, C. T.; Guiseppe, V. E.


    Concentrations of Cd, Cu, Pb and Zn in sediments of Egypt Bay in Hancock County, Maine, are elevated above background levels. The source of the contamination is Cu mining that occurred in the uplands adjacent to Egypt Stream between 1877 and 1885. Egypt Stream is a tributary to Egypt Bay. Egypt Bay is part of the Taunton Bay estuary system. The Hagan Mine was one of the mines extracting metals from the sulfide deposits in Downeast Maine north of Penobscot Bay. Metal concentrations were determined using ICP-AES after sample digestion with nitric acid. Soil collected from the coarse textured mine tailings pile contained elevated concentrations of Cd, Cu, Pb and Zn, but the majority of the surface soils at the Hagan Mine site were not contaminated. Estuary sediments from the surface to 100 cm depth were collected in four locations within Egypt Bay. Below 40 cm, metal concentrations in sediments were similar to those in uncontaminated upland soils. Metal concentrations in the estuary sediments between the surface and 26 cm were above background levels. According to 210Pb dating, the sediment at 26-34 cm depth was likely to have been deposited at the time the historic mines were in operation. Concentrations of Cd, Cu, Pb, and Zn in sediment from the 32-34 cm depth interval are similar to concentrations in the upland soil sample from the mine tailings pile. Elevated Pb concentrations in sediments from the surface to 24 cm are from atmospheric Pb deposition from anthropogenic sources. Sediment in the top 10 cm of the estuary has been mixed both by the polychaete worm Nereis virens and by those harvesting the worms for sale as fish bait.

  8. Mass balances of mercury and nitrogen in burned and unburned forested watersheds at Acadia National Park, Maine, USA

    Nelson, S.J.; Johnson, K.B.; Kahl, J.S.; Haines, T.A.; Fernandez, I.J.


    Precipitation and streamwater samples were collected from 16 November 1999 to 17 November 2000 in two watersheds at Acadia National Park, Maine, and analyzed for mercury (Hg) and dissolved inorganic nitrogen (DIN, nitrate plus ammonium). Cadillac Brook watershed burned in a 1947 fire that destroyed vegetation and soil organic matter. We hypothesized that Hg deposition would be higher at Hadlock Brook (the reference watershed, 10.2 ??g/m2/year) than Cadillac (9.4 ??g/m2/year) because of the greater scavenging efficiency of the softwood vegetation in Hadlock. We also hypothesized the Hg and DIN export from Cadillac Brook would be lower than Hadlock Brook because of elemental volatilization during the fire, along with subsequently lower rates of atmospheric deposition in a watershed with abundant bare soil and bedrock, and regenerating vegetation. Consistent with these hypotheses, Hg export was lower from Cadillac Brook watershed (0.4 ??g/m2/year) than from Hadlock Brook watershed (1.3 ??g/m2/year). DIN export from Cadillac Brook (11.5 eq/ ha/year) was lower than Hadlock Brook (92.5 eq/ha/year). These data show that ??50 years following a wildfire there was lower atmospheric deposition due to changes in forest species composition, lower soil pools, and greater ecosystem retention for both Hg and DIN. ??

  9. Shifts in controls on the temporal coherence of throughfall chemical flux in Acadia National Park, Maine, USA

    Nelson, Sarah J.; Webster, Katherine E.; Loftin, Cynthia S.; Weathers, Kathleen C.


    Major ion and mercury (Hg) inputs to terrestrial ecosystems include both wet and dry deposition (total deposition). Estimating total deposition to sensitive receptor sites is hampered by limited information regarding its spatial heterogeneity and seasonality. We used measurements of throughfall flux, which includes atmospheric inputs to forests and the net effects of canopy leaching or uptake, for ten major ions and Hg collected during 35 time periods in 1999–2005 at over 70 sites within Acadia National Park, Maine to (1) quantify coherence in temporal dynamics of seasonal throughfall deposition and (2) examine controls on these patterns at multiple scales. We quantified temporal coherence as the correlation between all possible site pairs for each solute on a seasonal basis. In the summer growing season and autumn, coherence among pairs of sites with similar vegetation was stronger than for site-pairs that differed in vegetation suggesting that interaction with the canopy and leaching of solutes differed in coniferous, deciduous, mixed, and shrub or open canopy sites. The spatial pattern in throughfall hydrologic inputs across Acadia National Park was more variable during the winter snow season, suggesting that snow re-distribution affects net hydrologic input, which consequently affects chemical flux. Sea-salt corrected calcium concentrations identified a shift in air mass sources from maritime in winter to the continental industrial corridor in summer. Our results suggest that the spatial pattern of throughfall hydrologic flux, dominant seasonal air mass source, and relationship with vegetation in winter differ from the spatial pattern of throughfall flux in these solutes in summer and autumn. The coherence approach applied here made clear the strong influence of spatial heterogeneity in throughfall hydrologic inputs and a maritime air mass source on winter patterns of throughfall flux. By contrast, vegetation type was the most important influence on

  10. Flow and sorption controls of groundwater arsenic in individual boreholes from bedrock aquifers in central Maine, USA

    To understand the hydrogeochemical processes regulating well water arsenic (As) evolution in fractured bedrock aquifers, three domestic wells with [As] up to 478 μg/L are investigated in central Maine. Geophysical logging reveals that fractures near the borehole bottom contribute 70–100% of flow. Borehole and fracture water samples from various depths show significant proportions of As (up to 69%) and Fe (93–99%) in particulates (> 0.45 μm). These particulates and those settled after a 16-day batch experiment contain 560–13,000 mg/kg of As and 14–35% weight/weight of Fe. As/Fe ratios (2.5–20 mmol/mol) and As partitioning ratios (adsorbed/dissolved [As], 20,000–100,000 L/kg) suggest that As is sorbed onto amorphous hydrous ferric oxides. Newly drilled cores also show enrichment of As (up to 1300 mg/kg) sorbed onto secondary iron minerals on the fracture surfaces. Pumping at high flow rates induces large decreases in particulate As and Fe, a moderate increase in dissolved [As] and As(III)/As ratio, while little change in major ion chemistry. The δD and δ18O are similar for the borehole and fracture waters, suggesting a same source of recharge from atmospheric precipitation. Results support a conceptual model invoking flow and sorption controls on groundwater [As] in fractured bedrock aquifers whereby oxygen infiltration promotes the oxidation of As-bearing sulfides at shallower depths in the oxic portion of the flow path releasing As and Fe; followed by Fe oxidation to form Fe oxyhydroxide particulates, which are transported in fractures and sorb As along the flow path until intercepted by boreholes. In the anoxic portions of the flow path, reductive dissolution of As-sorbed iron particulates could re-mobilize As. For exposure assessment, we recommend sampling of groundwater without filtration to obtain total As concentration in groundwater. - Highlights: • Most Fe and some As exist as particulates in the tested borehole and fracture water.

  14. Comparison of Bulk and Compound-Specific Carbon Isotope Analyses and Determination of Carbon Sources to Salt Marsh Sediments Using n-Alkane Distributions (Maine, USA)

    Tanner, B. R.; Uhle, M. E.; Kelley, J. T.; Mora, C. I.


    Sources of sedimentary organic matter to a Morse River, Maine (USA) salt marsh over the last 3390+/-60 RCYBP are determined using distribution patterns of n-alkanes as well as bulk and compound-specific carbon isotopic analysis. Marsh foraminiferal counts indicate the ubiquitous presence of zone 1B deposits, suggesting that the deposits were laid down ~0.2 to 0.5m above mean high water. Distributions of n-alkanes show a primary contribution from higher plants, confirmed by an average ACL value of 27.5 for the core sediments and CPI values above 3. Many sample depths have a maximum abundance at the C25 alkane. Ten low marsh, high marsh, and higher-high marsh plant species common to Maine salt marshes were sampled, including Spartina alterniflora, Spartina patens, Juncus gerardi and Solidago sempervirens. The ACL value for the average of the 10 marsh species is 29.1. Salicornia europa, usually not considered to be a dominant species in Maine marshes, has a similar n-alkane distribution to many of the salt marsh sediments, suggesting that it is an important source to the biomass of the marsh through time. Bacterial degradation or algal inputs to the marsh sediments appear to be minor. Compound specific carbon isotopic analyses of the C27 alkanes are, on average, 7.2ppt. depleted relative to bulk values, but the two records are strongly correlated (R2 = 0.87), suggesting that marsh plants are "swamping" the bulk carbon isotopic signal. The apparent abundance of a subordinate (though common) salt marsh plant species (Salicornia europa) within our core underscores the importance of using caution when applying mixing models of relatively few plant species to marsh sediments.

  16. Paleotsunamis Evidence In The Augusta Bay (Eastern Sicily, Italy)

    Smedile, A.; de Martini, P.; Barbano, M. S.; Pantosti, D.; Gerardi, F.; Del Carlo, P.; Bellucci, L. G.; Gasperini, L.; Sagnotti, L.; Polonia, A.; Pirrotta, C.


    The Augusta Bay, in Eastern Sicily (Italy), was repeatedly hit by tsunami waves related to large historical earthquakes (e.g. 1908, 1693, 1169). The area is characterized by coastal lowlands or lagoons, and by a relatively wide continental shelf with a thick late-Holocene record that has been investigated through the acquisition of a tight grid of CHIRP-sonar profiles. Well targeted sediment samples have been collected both offshore and inland. The integrated interpretation of the geophysical and geological data has been carried out in order to recognize, date and correlate key-layers in the sediment column that may be directly or indirectly related to tsunami events. A total of 26 cores were collected inland at a maximum distance of 530 m from the present coastline. The clay and silt dominated stratigraphy is intercalated by at least 5 high-energy or anomalous depositional layers, repeatedly found in several cores. These layers are made of coarse to fine sand with sharp basal contacts and present a bioclastic component made of microfauna (foraminifera) and shell fragments both suggestive of a marine provenance. Chronological constraints on the age of these deposits is based on AMS radiocarbon datings and on the attribution of a tephra layer to the 122 BC Etna eruption (thanks to petro- chemical and morphoscopic analyses). Integrating these data, the inland sequence spans the last 4100 yrs and the two uppermost high-energy events could be related to the AD 1169 and 1693 historical tsunamis. The offshore record was studied from a 6.7 m-long piston-core collected at 70 m water depth. The homogeneous sequence of dark gray mud is interrupted at -3 m by the same Etna tephra deposit found inland. Through the analysis of tephrostratigraphy, radiocarbon datings, high resolution paleomagnetic analysis and radioactive tracers, the entire core sequence has been dated back to the last 4500 yrs. Moreover, the quantitative micropaleontological analysis on the benthic

    Mechanisms and timescales responsible for pockmark formation and maintenance remain uncertain, especially in areas lacking extensive thermogenic fluid deposits (e.g., previously glaciated estuaries). This study characterizes seafloor activity in the Belfast Bay, Maine nearshore pockmark field using (1) three swath bathymetry datasets collected between 1999 and 2008, complemented by analyses of shallow box-core samples for radionuclide activity and undrained shear strength, and (2) historical bathymetric data (report and smooth sheets from 1872, 1947, 1948). In addition, because repeat swath bathymetry surveys are an emerging data source, we present a selected literature review of recent studies using such datasets for seafloor change analysis. This study is the first to apply the method to a pockmark field, and characterizes macro-scale (>5 m) evolution of tens of square kilometers of highly irregular seafloor. Presence/absence analysis yielded no change in pockmark frequency or distribution over a 9-year period (1999-2008). In that time pockmarks did not detectably enlarge, truncate, elongate, or combine. Historical data indicate that pockmark chains already existed in the 19th century. Despite the lack of macroscopic changes in the field, near-bed undrained shear-strength values of less than 7 kPa and scattered downcore 137Cs signatures indicate a highly disturbed setting. Integrating these findings with independent geophysical and geochemical observations made in the pockmark field, it can be concluded that (1) large-scale sediment resuspension and dispersion related to pockmark formation and failure do not occur frequently within this field, and (2) pockmarks can persevere in a dynamic estuarine setting that exhibits minimal modern fluid venting. Although pockmarks are conventionally thought to be long-lived features maintained by a combination of fluid venting and minimal sediment accumulation, this suggests that other mechanisms may be equally active in

  2. Comparison of bulk and compound-specific δ 13C analyses and determination of carbon sources to salt marsh sediments using n-alkane distributions (Maine, USA)

    Tanner, Benjamin R.; Uhle, Maria E.; Mora, Claudia I.; Kelley, Joseph T.; Schuneman, Patrick J.; Lane, Chad S.; Allen, Evan S.


    Sources of sedimentary organic matter to a Morse River, Maine (USA) salt marsh over the last 3390 ± 60 RCYBP (Radiocarbon Years Before Present) are determined using distribution patterns of n-alkanes, bulk carbon isotopic analysis, and compound-specific carbon isotopic analysis. Marsh foraminiferal counts suggest a ubiquitous presence of high marsh and higher-high marsh deposits (dominated by Trochammina macrescens forma macrescens, Trochammina comprimata, and Trochammina inflata), implying deposition from ˜0.2 m to 0.5 m above mean high water. Distributions of n-alkanes show a primary contribution from higher plants, confirmed by an average chain length value of 27.5 for the core sediments, and carbon preference index values all >3. Many sample depths are dominated by the C 25 alkane. Salicornia depressa and Ruppia maritima have similar n-alkane distributions to many of the salt marsh sediments, and we suggest that one or both of these plants is either an important source to the biomass of the marsh through time, or that another unidentified higher plant source is contributing heavily to the sediment pool. Bacterial degradation or algal inputs to the marsh sediments appear to be minor. Compound-specific carbon isotopic analyses of the C 27 alkane are on average 7.2‰ depleted relative to bulk values, but the two records are strongly correlated ( R2 = 0.89), suggesting that marsh plants dominate the bulk carbon isotopic signal. Our study underscores the importance of using caution when applying mixing models of plant species to salt marsh sediments, especially when relatively few plants are included in the model.

  5. An integrated approach to the assessment of pollutant delivery chronologies to impacted areas: Hg in the Augusta Bay (Italy).

    Bellucci, Luca Giorgio; Giuliani, Silvia; Romano, Stefania; Albertazzi, Sonia; Mugnai, Cristian; Frignani, Mauro


    Assessing pollution levels and trends in heavily impacted environments is important but hardly achievable due to the difficulty of recovering suitable undisturbed sediment records. An integrated approach is here presented to solve this kind of problem. It was adopted in the Augusta Bay (Italy) for the study of Hg historical inputs and present trends. Archive information on dredging and mud disposal, together with bathymetry and high-resolution seismic profiles, were used to identify suitable sampling sites. Undisturbed sediment cores were collected in the port and bay. Sediments were analyzed for depth distributions of radiotracers ((210)Pb and (137)Cs), Hg, and main sediment parameters (magnetic susceptibility, grain size, dry bulk density, mineralogy, and organic carbon and nitrogen contents). Hexachlorobenzene (HCB) was also analyzed as an additional time tracer, since its production history in the area was well-known. Results show that peak Hg contamination (up to 575 mg·kg(-1)) was reached in the 1970s. Technological improvements and waste treatment in the following years determined a consistent decrease, but high concentrations still affect surficial sediments (0.25-92 mg·kg(-1)). Hg-HCB correlation suggests that this situation is likely the effect of resuspension and redistribution of deep sediments by dredging and naval traffic. PMID:22233219

  6. Worst-case scenario approach to the tsunami hazard assessment for the coastal areas between Augusta and Siracusa, eastern Sicily, Italy

    Armigliato, Alberto; Pagnoni, Gianluca; Zaniboni, Filippo; Tinti, Stefano


    The province of Siracusa encompasses a very long portion of the eastern Sicily coastline, ranging from the southern part of the Catania Gulf to the north down to the southern-eastern end of the island, known as Capo Passero. Within this domain, the area comprised between the towns of Augusta and Siracusa has been selected as one of the sites for the testing of innovative methods for tsunami hazard, vulnerability and risk assessment and reduction developed in the frame of the EU Project called ASTARTE - Assessment, STrategy And Risk Reduction for Tsunamis in Europe (Grant 603839, 7th FP, ENV.2013.6.4-3). The selection was driven by two main reasons. First, the area was hit by at least seven tsunamis in the approximate time interval from 1600 BC to present, as can be deduced from historical catalogues and paleo-tsunami deposits analysis: the most famous are probably the 21 July 365, 4 February 1169, 11 January 1693 and 28 December 1908 tsunamis. Secondly, as a whole, the test site has a strong relevance from the industrial, commercial, military, historical and cultural points of view: here it is sufficient to mention the huge petrochemical pole in the Augusta bay and the listing of Siracusa as UNESCO World Heritage Site since 2005. This contribution deals with the tsunami hazard assessment for the Augusta-Siracusa area, approached through the worst-case credible scenario technique. We selected five main source areas: the choice is driven mainly by the already mentioned fact that historical catalogues and paleo-tsunami studies tell us that the area under investigation can be impacted by tsunamis generated both in the near-field and in the far-field. The five areas include the Hyblaean-Malta escarpment and the Messina Straits in the near-field, the western and eastern lobes of the Ionian subduction zone in the intermediate field, and the western Hellenic Trench in the far-field. In each source area, a selection of possible faults was made, whose characteristics and

  7. Integrated Archaeological and Geophysical Surveys in the Historical Center of Augusta (Eastern Sicily, Italy).

    Malfitana, Daniele; Leucci, Giovanni; Fragalà, Giovanni; Cacciaguerra, Giuseppe; De Giorgi, Lara


    Syracuse (Eastern Sicily, Italy) and its vast hinterland played a crucial role in the economy of ancient Sicily, largely because of the management, exploitation and trade of agricultural supply. Nevertheless, the socio-economic aspects of its territorial management and the relation between the countryside and coastal centres in the complex system of the Mediterranean markets have not yet been analysed in depth by scholars. Despite the historical, monumental and economic importance of the surrounding area of Syracuse in the Antiquity, the knowledge of the roman and medieval landscape and archaeological sites are still limited. The research undertaken by Istituto per i Beni Archeologici e Monumentali - CNR of Catania (Sicily, Italy) attempted to remedy this omission by outlining a preliminary picture of the rich historical and archaeological heritage of Syracuse and its surrounding territory, which will be analysed using a multidisciplinary approach. Augusta, a town near Syracuse (Sicily), was founded by emperor Frederick of Suavia between 1232 and 1239. In medieval period, the area of Giardini Pubblici was the downtown and untill the XVII Cent. AD it was occupied by two urban blocks of buildings. In 1670 they were demolished to allow free area firing line from the near castle. Integrated archaeological and geophysical investigations allowed a wide range knowledge of the roman and medieval landscapes, archaeological sites and monumental remains. Particularly the geophysical surveys undertaken in the historical center of Augusta, by means Ground-penetrating Radar (GPR), allowed a 3D reconstruction of archaeological structures in the subsoil until the depth of about 4m. The geophysical survey has identified the building of medieval and modern urban settlement of Augusta and has allowed to recreate the urban plan and its transformation.

  10. Sediment transport modelling based on grain size trend analysis in Augusta Harbour (Sicily)

    Barbera, Giuseppe; Feo, Roberto; Freni, Gabriele


    To support marine civil engineer in pollutant studies, sediment management or dredging operations, is useful to know how the sediments move in accumulation basin. This paper investigates the dynamic of the sediment path using a two-dimensional numeric model: the Grain Size Trend Analysis (GSTA). The GSTA was applied using GiSedTrend plugin, under GIS software. The case study is the Augusta Harbour, which is one of the most polluted Italian harbours. It is the marine part of the Site of National Interest (SNI) of Priolo Gargallo (Siracusa, Italy) and it can be hydrodynamically considered as a lagoon. Two scenarios were obtained by using different geostatistical criteria.

  13. Under Augustus sign: the role of Astronomy in the foundation of Augusta Praetoria Salassorum

    Bertarione, Stella Vittoria


    Augusta Praetoria Salassorum, modern Aosta, was founded around 25 BC to celebrate the victory of Augustus army on the Salassi. Aosta is a city of the founder under many respects; for instance, one of the two twin temples of the forum was devoted to Augustus, and a huge triumphal arc to the ruler still welcomes the town visitors. Recently, a sculpted block has been uncovered, still in its original position, on a corner of one of the town towers. The block carries reliefs, such as a plough and a spade, which are clearly related to the town foundation ritual. As a consequence, we carried out an archaeoastronomical analysis of the original urban plan taking into account the complex natural horizon of the Alps in which Aosta valley is nested. The results show that the town was very likely oriented in such a way as to pinpoint Augustus associations with the cosmic signs of renewal: the winter solstice and the Capricorn.

Although some authors interpreted it differently, as a funeral banquet with a portrait of the dead person, nobody has yet proposed the Christian interpretation presented here: the image of Noah emerging from the Ark, shown on the front of a sarcophagus lid, and the representation of a celestial banquet celebrating the salvation of the dead. The piece is dated to the last quarter of the 3rd century AD and thus is the first archaeological evidence of Christianity in the colonia Augusta EmeritaSe estudia un relieve conservado en el Museo Nacional de Arte Romano de Mérida (Badajoz, España que durante mucho tiempo ha sido considerado como una representación de Mitra saxígeno y, por tanto, un documento más entre los testimonios de cultos orientales en la capital de la Lusitania. A pesar de que algunos autores dieron una interpretación diferente, esto es, que se trataba de un banquete funerario con la representación del difunto, ninguno ha propuesto la identificación con una escena cristiana que aquí se propone, representada en el frente de una tapa de sarcófago, con la imagen de Noé saliendo del arca y, a continuación, una representación del banquete celestial en el que participan los justos. La pieza se fecha en el último cuarto del siglo III d.C. y se convierte así en el primer testimonio arqueológico de la presencia de cristianos en la colonia Augusta Emerita.

  16. Past climate, future perspective: an exploratory analysis using climate proxies and drought risk assessment to inform water resources management and policy in Maine, USA.

    Gupta, Avirup Sen; Jain, Shaleen; Kim, Jong-Suk


    In recent decades, significant progress has been made toward reconstructing the past climate record based on environmental proxies, such as tree rings and ice core records. However, limited examples of research that utilizes such data for water resources decision-making and policy exist. Here, we use the reconstructed record of Palmer Drought Severity Index (PDSI), dating back to 1138AD to understand the nature of drought occurrence (severity and duration) in the state of Maine. This work is motivated by the need to augment the scientific basis to support the water resources management and the emerging water allocation framework in Maine (Maine Department of Environmental Protection, Chapter 587). Through a joint analysis of the reconstructed PDSI and historical streamflow record for twelve streams in the state of Maine, we find that: (a) the uncertainties around the current definition of natural drought in the Chapter 587 (based on the 20th century instrumental record) can be better understood within the context of the nature and severity of past droughts in this region, and (b) a drought index provides limited information regarding at-site hydrologic variations. To fill this knowledge gap, a drought index-based risk assessment methodology for streams across the state is developed. Based on these results, the opportunities for learning and challenges facing water policies in a changing hydroclimate are discussed. PMID:21075507

  19. Associated terrestrial and marine fossils in the late-glacial Presumpscot Formation, southern Maine, USA, and the marine reservoir effect on radiocarbon ages

    Thompson, Woodrow B.; Griggs, Carol B.; Miller, Norton G.; Nelson, Robert E.; Weddle, Thomas K.; Kilian, Taylor M.


    Excavations in the late-glacial Presumpscot Formation at Portland, Maine, uncovered tree remains and other terrestrial organics associated with marine invertebrate shells in a landslide deposit. Buds of Populus balsamifera (balsam poplar) occurred with twigs of Picea glauca (white spruce) in the Presumpscot clay. Tree rings in Picea logs indicate that the trees all died during winter dormancy in the same year. Ring widths show patterns of variation indicating responses to environmental changes. Fossil mosses and insects represent a variety of species and wet to dry microsites. The late-glacial environment at the site was similar to that of today's Maine coast. Radiocarbon ages of 14 tree samples are 11,907 ± 31 to 11,650 ± 50 14C yr BP. Wiggle matching of dated tree-ring segments to radiocarbon calibration data sets dates the landslide occurrence at ca. 13,520 + 95/-20 cal yr BP. Ages of shells juxtaposed with the logs are 12,850 ± 65 14C yr BP ( Mytilus edulis) and 12,800 ± 55 14C yr BP ( Balanus sp.), indicating a marine reservoir age of about 1000 yr. Using this value to correct previously published radiocarbon ages reduces the discrepancy between the Maine deglaciation chronology and the varve-based chronology elsewhere in New England.

  20. Abroma augusta Linn bark extract-mediated green synthesis of gold nanoparticles and its application in catalytic reduction

    Das, Subhajit; Bag, Braja Gopal; Basu, Ranadhir


    The bark extract of Abroma augusta Linn is rich in medicinally important phytochemicals including antioxidants and polyphenols. First one step green synthesis of gold nanoparticles (AuNPs) has been described utilizing the bark extract of Abroma augusta L. and chloroauric acid under very mild reaction conditions. The phytochemicals present in the bark extract acted both as a reducing as well as a stabilizing agent, and no additional stabilizing and capping agents were needed. Detailed characterizations of the stabilized AuNPs were carried out by surface plasmon resonance spectroscopy, high resolution transmission electron microscopy, and X-ray diffraction studies. The catalytic activity of the freshly synthesized gold nanoparticles has been demonstrated for the sodium borohydride reduction of 4-nitrophenol to 4-aminophenol, and the kinetics of the reduction reaction have been studied spectrophotometrically.

  2. Anthropogenic and natural lead isotopes in Fe-hydroxides and Fe-sulphates in a watershed associated with arsenic-enriched groundwater, Maine, USA

    Ayuso, Robert A.; Foley, Nora K.


    A survey of the natural and anthropogenic sources of lead contributing to secondary minerals in sulphidic schists associated with arsenic-enriched groundwater in Coastal Maine shows that the most likely source is natural Pb, particularly from coexisting sulphide minerals. The secondary minerals also reflect notable contributions from anthropogenic Pb. The Pb isotopes establish pathways by which Pb, and by inference As, could have been transported from As-bearing minerals (arsenian pyrite, arsenopyrite, lollingite, orpiment, arsenic oxide and others), via sulphide oxidation or carbonation reactions into multiple generations of secondary minerals (goethite, hematite, jarosite, natrojarosite and others). Lead isotopic compositions of the sulphides and secondary minerals determined by thermal ionization mass spectrometry (n=53) range widely. Lead and As contents of the sulphides and secondary minerals overlap, and are generally positively correlated. Pyrite, the dominant sulphide in sulphidic schists associated with As-enriched groundwater in Coastal Maine, has values of 206Pb/204Pb from 18.186 to 18.391, 207Pb/204Pb from 15.617 to 15.657, 208Pb/204Pb from 38.052 to 38.210, 206Pb/207Pb from c. 1.1625 to 1.1760 and 208Pb/207Pb from c. 2.4276 to 2.4394. Mixtures of Fe-hydroxide and oxide minerals (predominantly goethite and hematite) and secondary Fe-sulphate minerals (jarosite, natrojarosite, rozenite and melanterite) in the sulphidic schists have overlapping but generally higher values of 206Pb/204Pb from 18.495 to 19.747 (one sample at 21.495), 207Pb/204Pb from 15.595 to 15.722 (one sample at 15.839), 208Pb/204Pb from 38.186 to 39.162,206Pb/207Pb from c.1.1860 to 1.2575 (one sample at 1.3855) and 208Pb/207Pb from c. 2.4441 to 2.4865 than the sulphides. Sulphides from Zn-Pb metal mines are somewhat less radiogenic than sulphides from the schists. Other sulphides (mostly pyrite) associated with pegmatites and granitic rocks are heterogeneous and more

  3. Tsunami vulnerability and damage for buildings analyzed by means of two methods (PTVA-3 and SCHEMA) in the area of Augusta and Siracusa, eastern Sicily, Italy

    Pagnoni, Gianluca; Tinti, Stefano


    aim of this work is to compare the vulnerability and damage analyses carried out by means of the PTVA-3 and the SCHEMA methods on the same data set, that is the urban and port areas of Siracusa and Augusta in order to highlight similarities and discrepancies. In this preliminary analysis the coastal inundation was not derived from tsunami simulations, but was assumed to be constant along the coast (bathtub hypothesis) and was taken to be 5 m and 10 m respectively for Siracusa and Augusta. The main outcome of the compared analysis is that the two methods do not provide completely overlapping vulnerability and damage maps, though they use equivalent 5-degree scales. In general the PTVA-3 method tends to overestimate the damage, although there are several counterexamples where PTVA-3 foresees less damage than SCHEMA. The differences we found in the assessment opens the question of how to treat uncertainties in the vulnerability and damage analyses, which is a problem often overlooked, but of crucial importance for the application and for civil authorities.

  4. Factors affecting public support for forest-based biorefineries: A comparison of mill towns and the general public in Maine, USA

    Community views toward the risks and benefits of emerging renewable energy technologies are important factors in facility siting decisions and their eventual success. While the actual socioeconomic and biophysical impacts of proposed industrial developments are fraught with uncertainty, understanding public perceptions is critical in managing costs and benefits to local citizens. Here, we explore the social acceptability of forest-based biorefineries in Maine using random utility modeling to identify how project attributes and citizen characteristics interact to affect level of support. Using a statewide sample (Statewide) and a subsample of mill towns (Mill Towns), we found that: (1) in both samples, individual characteristics had similar coefficients and significance levels except for pro-environment attitudes; (2) the coefficients related to the industry’s negative attributes were notably different between the two samples, while positive attributes were not; (3) in both samples, positive industry attributes such as “producing products from a sustainable resource” and “increased economic development” were the most influential variables in determining the level of support for a new biorefinery in an individual’s community; and (4) in general, Mill Town respondents were more accepting of potential negative attributes such as increased levels of truck traffic, odor, noise, and air and water pollution. - Highlights: • We examined social views of bioproducts processing in mill towns and statewide. • Environmental sustainability was a major concern expressed by both samples. • Views were affected by proximity to processing, and by respondent characteristics. • Public concerns should be considered along the entire supply chain. • Views toward biorefineries may be influenced by views of related industries

  6. Characterization of concrete from Roman theatre and amphitheater in Emerita Augusta (Mérida, Spain)

    Mota-Lopez, Maria Isabel; Fort, Rafael; Alvarez de Buergo, Monica; Pizzo, Antonio; Maderuelo-Sanz, Ruben; Meneses-Rodríguez, Juan Miguel


    The restoration of historical buildings is very important for the history and culture of the cities and their population. It requires an advanced knowledge of the building materials used for the construction of these structures. Previously to any intervention in historical buildings, it is necessary a historic-scientific study of the original material. Historic mortars or concretes can reveal us different composition and the dependence on the geographical location and the time period of its construction. Historical concretes are complex systems that contain aerial or hydraulic binders or a blend of them, with aggregates, not always crystalline, and others elements that interact with the binder. The use of different techniques for microstructural characterization of materials, like optical microscopy, X-ray diffractometry or petrophysical analysis, allows the determination of the composition and some properties of these concretes. However, each technique has its own limits and, in many cases, several characterization techniques must be used to obtain coherent and reliable results. The present study focuses on the compositional characterization of Roman concrete from Roman buildings for public spectacles of Emerita Augusta, Mérida, Spain. An advanced knowledge of the Roman concrete composition is required to get a reliable restoration and preservation of these ancient monuments. Various samples of concrete were extracted from different zones from this archaeological site. The concrete was studied through mineralogical analysis (petrographic microscope and XRD) and petrophysical properties determination (bulk and real density, open porosity, mercury porosimetry intrusion, compressive strength and Ultrasound propagation velocity). The results obtained allow us to know the original composition of the concrete and the provenance of the aggregates used in it.

  7. Retinal chromophore structure and Schiff base interactions in red-shifted channelrhodopsin-1 from Chlamydomonas augustae.

    Ogren, John I; Mamaev, Sergey; Russano, Daniel; Li, Hai; Spudich, John L; Rothschild, Kenneth J


    Channelrhodopsins (ChRs), which form a distinct branch of the microbial rhodopsin family, control phototaxis in green algae. Because ChRs can be expressed and function in neuronal membranes as light-gated cation channels, they have rapidly become an important optogenetic tool in neurobiology. While channelrhodopsin-2 from the unicellular alga Chlamydomonas reinhardtii (CrChR2) is the most commonly used and extensively studied optogenetic ChR, little is known about the properties of the diverse group of other ChRs. In this study, near-infrared confocal resonance Raman spectroscopy along with hydrogen-deuterium exchange and site-directed mutagenesis were used to study the structure of red-shifted ChR1 from Chlamydomonas augustae (CaChR1). These measurements reveal that (i) CaChR1 has an all-trans-retinal structure similar to those of the light-driven proton pump bacteriorhodopsin (BR) and sensory rhodopsin II but different from that of the mixed retinal composition of CrChR2, (ii) lowering the pH from 7 to 2 or substituting neutral residues for Glu169 or Asp299 does not significantly shift the ethylenic stretch frequency more than 1-2 cm(-1) in contrast to BR in which a downshift of 7-9 cm(-1) occurs reflecting neutralization of the Asp85 counterion, and (iii) the CaChR1 protonated Schiff base (SB) has stronger hydrogen bonding than BR. A model is proposed to explain these results whereby at pH 7 the predominant counterion to the SB is Asp299 (the homologue to Asp212 in BR) while Glu169 (the homologue to Asp85 in BR) exists in a neutral state. We observe an unusual constancy of the resonance Raman spectra over the broad range from pH 9 to 2 and discuss its implications. These results are in accord with recent visible absorption and current measurements of CaChR1 [Sineshchekov, O. A., et al. (2013) Intramolecular proton transfer in channelrhodopsins. Biophys.

  8. Modeling, Analysis, and Preservation Techniques for Historic Reinforced Concrete Structures in Seismic Prone Regions Case Study: Augusta Airship Hangar, Sicily

    Throughout the world there are hundreds of historic monuments and structures considered to be invaluable and irreplaceable. They are symbols of cultural identity and a means of educating people about history. Preservation of historic monuments and structures is therefore an important part of safeguarding these cultural heritage sites so that they retain their value for future generations.This report discusses a procedure for the investigation of seismic hazards in existing buildings and possible steps that can be taken to avoid damage caused by these hazards. The Augusta Airship Hangar located in Sicily, will be used as a case study however the topics addressed in this paper can be applied to other structures of historic value around the world.First state-of-the-art scanning procedures were used to create scale digital models that were imported into a structural analysis program. Within this program dynamic analyses were performed on the model based on actual ground motions taken close to the site. This data was used to determine the period and mode shapes of the structure. Then a nonlinear analysis, including a static pushover analysis, was implemented on a two-dimensional model of the structural frame. From this analysis the failure mechanisms of the structure were revealed with relation to an allowable roof displacement. The structural integrity of the structure was evaluated based on pre-defined performance goals. Finally multiple suggestions were made how the Augusta Airship Hangar might be repaired and strengthened so that this structure will not be destroyed should an earthquake occur.The results of our study show that historic structures, despite their age, can still be strong and ductile. Also there are a multitude of effective preservation and retrofit techniques that can be used to strengthen these historic structures, should an earthquake occur. Through this study, the Augusta Airship Hangar has proven to be not only a historic symbol for Sicily but

    Parker, E J; Misan, G; Shearer, M; Richards, L; Russell, A; Mills, H; Jamieson, L M


    Aboriginal Australian children experience profound oral health disparities relative to their non-Aboriginal counterparts. In response to community concerns regarding Aboriginal child oral health in the regional town of Port Augusta, South Australia, a child dental health service was established within a Community Controlled Aboriginal Health Service. A partnership approach was employed with the key aims of (1) quantifying rates of dental service utilisation, (2) identifying factors influencing participation, and (3) planning and establishing a program for delivery of Aboriginal children's dental services that would increase participation and adapt to community needs. In planning the program, levels of participation were quantified and key issues identified through semistructured interviews. After 3.5 years, the participation rate for dental care among the target population increased from 53 to 70 percent. Key areas were identified to encourage further improvements and ensure sustainability in Aboriginal child oral health in this regional location. PMID:22577401

  11. Un tesoro de tremises visigodos hallado en el llamado «Foro Provincial» de Augusta Emerita

    Mateos Cruz, Pedro


    Full Text Available Since 1999 we are working on a research project about the so called «Provincial Forum of Augusta Emerita». The project deals with the realisation of archaeological interventions in the various lots where remains of public architecture linked with this monumental ensemble have been documented. One of these interventions has been realised in a lot where remains of the so called «Temple of the Holguin-Street» appeared some years ago. During the works on the same site has been brought to light a treasure of twenty gold coins from the time of Leovigild hidden under the walls of a room which in late Antiquity reused the southern side of the Roman temple podium. This article is a study of these pieces set in context with their hiding position and the historical moment in which they have been in use.Desde el año 1999 estamos desarrollando un proyecto de investigación en el llamado «foro Provincial de Augusta Emerita»; el proyecto contempla la realización de intervenciones arqueológicas en los distintos solares donde se han documentado restos de arquitectura pública vinculados a este conjunto monumental. Una de estas intervenciones se ha efectuado en el solar donde hace años aparecieron los restos del denominado «templo de la C/ Holguín», lugar en el que, durante el desarrollo de los trabajos, apareció un tesoro de veinte monedas de oro de época de Leovigildo, oculto bajo los muros de una estancia que reutilizo en época tardoantigua el alzado Sur del podio del templo romano. En este artículo se realiza un estudio de estas piezas contextualizándolas con el lugar de ocultamiento y el momento histórico en que estuvieron en uso.

  14. Public health assessment for petitioned addendum, southern wood Piedmont Company, Augusta, Richmond County, Georgia, Region 4. Cerclis No. GAD051034387. Final report



    The Southern Wood Piedmont (SWP) Site is a former wood-treating facility in Augusta, Georgia. A petitioned public health assessment for this site was finalized in March, 1992. This addendum provides an evaluation of additional information that the Agency for Toxic Substances and Disease Registry (ATSDR) has received since the release of its last public health assessment. Based on this information, ATSDR concluded that the site posed a public health hazard prior to 1993. However, data acquired in 1993 confirm that the site no longer poses a public health hazard to the surrounding neighborhoods.

  19. Estimates of Cl atom concentrations and hydrocarbon kinetic reactivity in surface air at Appledore Island, Maine (USA), during International Consortium for Atmospheric Research on Transport and Transformation/Chemistry of Halogens at the Isles of Shoals

    Pszenny, Alexander A. P.; Fischer, Emily V.; Russo, Rachel S.; Sive, Barkley C.; Varner, Ruth K.


    Average hydroxyl radical (OH) to chlorine atom (Cl·) ratios ranging from 45 to 119 were determined from variability-lifetime relationships for selected nonmethane hydrocarbons (NMHC) in surface air from six different transport sectors arriving at Appledore Island, Maine, during July 2004. Multiplying these ratios by an assumed average OH concentration of 2.5 × 106 cm-3 yielded estimates of Cl· concentrations of 2.2 to 5.6 × 104 cm-3. Summed reaction rates of methane and more than 30 abundant NMHCs with OH and Cl· suggest that Cl· reactions increased the kinetic reactivity of hydrocarbons by 16% to 30% over that due to OH alone in air associated with the various transport sectors. Isoprene and other abundant biogenic alkenes were the most important hydrocarbon contributors after methane to overall kinetic reactivity.

  20. Assessment of mercury exposure in human populations: A status report from Augusta Bay (southern Italy).

    Bonsignore, Maria; Andolfi, Nunzia; Barra, Marco; Madeddu, Anselmo; Tisano, Francesco; Ingallinella, Vincenzo; Castorina, Maria; Sprovieri, Mario


    Here we investigate mercury concentrations in the blood (HgB), urine (HgU) and human hair (HgH) of 224 individuals from a coastal area (Eastern Sicily, SE Italy) strongly affected by Hg contamination from one of the largest chlor-alkali plants in Europe. The factors affecting the distribution of Hg and the extent of the exposure of individuals have been explored with a multidisciplinary approach. Multiple regression analyses, together with evidence of high levels of HgB (exceeding the HBMI recommended levels in 50% of cases) and HgH (exceeding the EPA reference dose in 70% of cases), primarily suggest that the consumption of local fish is the main source of Hg for humans. no. significant exposure to inorganic mercury was identified. Toxicokinetic calculations produced a provisional tolerable weekly intake (PTWI) level that, in most cases, exceeds international recommendations, particularly for residents in the studied area.

  1. Textural, mineralogical and stable isotope studies of hydrothermal alteration in the main sulfide zone of the Great Dyke, Zimbabwe and the precious metals zone of the Sonju Lake Intrusion, Minnesota, USA

    Li, C.; Ripley, E.M.; Oberthur, T.; Miller, J.D., Jr.; Joslin, G.D.


    Stratigraphic offsets in the peak concentrations of platinum-group elements (PGE) and base-metal sulfides in the main sulfide zone of the Great Dyke and the precious metals zone of the Sonju Lake Intrusion have, in part, been attributed to the interaction between magmatic PGE-bearing base-metal sulfide assemblages and hydrothermal fluids. In this paper, we provide mineralogical and textural evidence that indicates alteration of base-metal sulfides and mobilization of metals and S during hydrothermal alteration in both mineralized intrusions. Stable isotopic data suggest that the fluids involved in the alteration were of magmatic origin in the Great Dyke but that a meteoric water component was involved in the alteration of the Sonju Lake Intrusion. The strong spatial association of platinum-group minerals, principally Pt and Pd sulfides, arsenides, and tellurides, with base-metal sulfide assemblages in the main sulfide zone of the Great Dyke is consistent with residual enrichment of Pt and Pd during hydrothermal alteration. However, such an interpretation is more tenuous for the precious metals zone of the Sonju Lake Intrusion where important Pt and Pd arsenides and antimonides occur as inclusions within individual plagioclase crystals and within alteration assemblages that are free of base-metal sulfides. Our observations suggest that Pt and Pd tellurides, antimonides, and arsenides may form during both magmatic crystallization and subsolidus hydrothermal alteration. Experimental studies of magmatic crystallization and hydrothermal transport/deposition in systems involving arsenides, tellurides, antimonides, and base metal sulfides are needed to better understand the relative importance of magmatic and hydrothermal processes in controlling the distribution of PGE in mineralized layered intrusions of this type. ??

    Full Text Available Augusta has traditionally been placed in the tribe Rondeletieae, subfamily Cinchonoideae. However, recent molecular phylogenies positioned it near to Wendlandia (Ixoroideae, but locate A. longifolia near to the clade Ixoroidinae II. The study of A. longifolia afforded two coumarins, five flavonoids, three triterpenoids and one benzoic acid derivative. These metabolites reinforce the separation of Augusta as a monospecific genus, and Lindenia as a genus of three species, closely related to Wendlandia.Augusta tem sido tradicionalmente colocada na tribo Rondeletieae, Cinchonoideae subfamília.

  5. Main findings

    Licensing regimes vary from country to country. When the license regime involves several regulators and several licenses, this may lead to complex situations. Identifying a leading organisation in charge of overall coordination including preparation of the licensing decision is a useful practice. Also, if a stepwise licensing process is implemented, it is important to fix in legislation decisions and/or time points and to identify the relevant actors. There is considerable experience in civil and mining engineering that can be applied when constructing a deep geological disposal facility. Specific challenges are, however, the minimization of disturbances to the host rock and the understanding of its long-term behavior. Construction activities may affect the geo-hydraulic and geochemical properties of the various system components which are important safety features of the repository system. Clearly defined technical specifications and an effective quality management plan are important in ensuring successful repository implementation which is consistent with safety requirements. Monitoring plan should also be defined in advance. The regulatory organization should prepare itself to the licensing review before construction by allocating sufficient resources. It should increase its competence, e.g., by interacting early with the implementer and through its own R and D. This will allow the regulator to define appropriate technical conditions associated to the construction license and to elaborate a relevant inspection plan of the construction work. After construction, obtaining the operational license is the most important and crucial step. Main challenges include (a) establishing sufficient confidence so that the methods for closing the individual disposal units comply with the safety objectives and (b) addressing the issue of ageing of materials during a 50-100 years operational period. This latter challenge is amplified when reversibility/retrievability is required

  6. Phenotypes and Virulence among Staphylococcus aureus USA100, USA200, USA300, USA400, and USA600 Clonal Lineages.

    King, Jessica M; Kulhankova, Katarina; Stach, Christopher S; Vu, Bao G; Salgado-Pabón, Wilmara


    Staphylococcus aureus diseases affect ~500,000 individuals per year in the United States. Worldwide, the USA100, USA200, USA400, and USA600 lineages cause many of the life-threatening S. aureus infections, such as bacteremia, infective endocarditis, pneumonia, toxic shock syndrome, and surgical site infections. However, the virulence mechanisms associated with these clonal lineages, in particular the USA100 and USA600 isolates, have been severely understudied. We investigated the virulence of these strains, in addition to strains in the USA200, USA300, and USA400 types, in well-established in vitro assays and in vivo in the rabbit model of infective endocarditis and sepsis. We show in the infective endocarditis and sepsis model that strains in the USA100 and USA600 lineages cause high lethality and are proficient in causing native valve infective endocarditis. Strains with high cytolytic activity or producing toxic shock syndrome toxin 1 (TSST-1) or staphylococcal enterotoxin C (SEC) caused lethal sepsis, even with low cytolytic activity. Strains in the USA100, USA200, USA400, and USA600 lineages consistently contained genes that encode for the enterotoxin gene cluster proteins, SEC, or TSST-1 and were proficient at causing infective endocarditis, while the USA300 strains lacked these toxins and were deficient in promoting vegetation growth. The USA100, USA200, and USA400 strains in our collection formed strong biofilms in vitro, whereas the USA200 and USA600 strains exhibited increased blood survival. Hence, infective endocarditis and lethal sepsis are multifactorial and not intrinsic to any one individual clonal group, further highlighting the importance of expanding our knowledge of S. aureus pathogenesis to clonal lineages causative of invasive disease. IMPORTANCE S. aureus is the leading cause of infective endocarditis in the developed world, affecting ~40,000 individuals each year in the United States, and the second leading cause of bacteremia (D.

  7. Summary of main points

    In conjunction with its 6. annual meeting, the WPDD in close co-operation with the FSC held a Topical session on 'Stakeholder Involvement in Decommissioning' on November 14, 2005. The session was attended by 36 participants totally representing 14 NEA member countries and 2 international organisations. Two keynote addresses were given at the Topical Session. The first one treated of what is needed for robust decisions and how to bring all stakeholders into the debate. In the second keynote address a summary was made on what have been said on stakeholder involvement in decommissioning during earlier meetings of the WPDD. The main part of the session was then devoted to views from different stakeholders regarding their role and their involvement. This part contained viewpoints from local communities (Kaevlinge in Sweden and Port Hope in Canada), authorities (Scottish Executive and CSNC) and operators (EDF from France and EWN from Germany). Case studies from the decommissioning of Dounrey in the UK and from Trojan and Main Yankee in the USA were presented in the end part of the Topical session followed by a summary and lessons learnt report by the Rapporteur.

  9. Assessment of sediment contamination in Casco Bay, Maine, USA

    The current status of contaminant concentrations in Casco Bay, decadal trends of these contaminants and changes in their geographical distribution are assessed using sediment samples collected approximately 10 years apart. In general, regulated contaminants appeared to be decreasing in concentration. Total PAH and dioxins/furans concentrations did not significantly change over this period. Total organochlorine pesticides, 4,4-DDE, 4,4-DDD, total DDT, PCB, tributyltin and total butyltin decreased in concentration. Trace element concentrations in sediments decreased at the majority of the sampling sites for chromium, nickel, and selenium while arsenic, cadmium, copper, lead, mercury, silver, and zinc remained relatively constant. None of the contaminants measured has increased by more than a factor of 2. Selected sites located in the Inner Bay, where concentrations are higher and new inputs were more likely, showed increased concentrations of contaminants. Most contaminants were not found at concentrations expected to adversely affect sediment biota based on ERL/ERM guidelines. - Sediment studies indicate decadal decreases for many chemical contaminants in Casco Bay

  15. « Ni bas-bleu, ni pot-au-feu » : la conception de « la » femme selon Augusta Moll-Weiss (France, tournant des XIXe-XXe siècles

    Sandrine Roll


    Full Text Available Cet article analyse les idées et l’œuvre de la directrice de l’École des mères, Augusta Moll-Weiss. Dans le contexte du tournant des XIXe-XXe siècles où l’éloge de la ménagère est un thème récurrent des discours moralisateurs émanant des ouvriers ou des bourgeois, Augusta Moll-Weiss met en place un projet de cours ménagers. Son œuvre offre une approche singulière de ce que des activités reconnues comme typiquement féminines peuvent offrir aux femmes. Loin de former uniquement des « fées du logis », les cours professés à l’École des mères donnent aussi aux élèves la possibilité de se préparer à une carrière professionnelle. Augusta Moll-Weiss imagine alors pléthore de débouchés qui placent les activités « du souci des autres » dans la sphère du travail social. Son engagement en faveur de l’enseignement ménager s’accompagne d’une réflexion sur de nouveaux modèles domestiques susceptibles d’accompagner l’entrée des femmes sur le marché du travail. La rationalisation et le partage sexué des tâches domestiques ainsi que la question du temps partiel sont au cœur de son projet. Aux marges de la philanthropie et du féminisme, Augusta Moll-Weiss s’engage donc dans une stratégie de reconnaissance du rôle des femmes dans l’espace civique. Après avoir présenté l’œuvre scolaire de cette femme, cet article s’intéresse à sa vision de la « Ménagère nouvelle » et à son approche du féminisme.This article explores the ideas and works of the Augusta Moll-Weiss, head of the École des mères.

  16. Health assessment for petitioned public health assessment, Southern Wood Piedmont Company, Augusta, Richmond County, Georgia, Region 4. CERCLIS No. GAD051034387. Final report


    The Southern Wood Piedmont (SWP) site is located in Augusta, Georgia. Wood-treating operations were conducted at the site from 1923 until 1988. Closure operations at the facility were regulated under the Resource Conservation and Recovery Act (RCRA). When the facility was operating, wastewaters containing hazardous substances were discharged to an on-site, unlined surface impoundment and to off-site drainage ditches. These disposal practices resulted in contamination of groundwater with high concentrations of wood treatment chemicals. Currently, all of the homes in the affected neighborhoods are reportedly connected to the public water system. Sediment samples from drainage ditches along the eastern border of the SWP facility were contaminated with site-related chemicals. The SWP site is categorized as an indeterminate public health hazard. Past exposures to on-site and off-site contamination may have exceeded current dose levels. ATSDR has recommended to the U.S. Environmental Protection Agency (EPA) and the Georgia Environmental Protection Division (EPD) that action be taken.

  1. Analysis of complex pumping interactions during an aquifer test conducted at a well field in the coastal plain near Augusta, Georgia, October 2009

    Gonthier, Gerald J.


    A 24-hour aquifer test was conducted in Well Field 2 near Augusta, Georgia, October 21–22, 2009, to characterize the hydraulic properties of the Midville aquifer system. The selected well was pumped at a rate of 684 gallons per minute. At the initiation of aquifer-test pumping, water levels in each of eight wells monitored for the test were still recovering from the well-field production. Because water levels had not stabilized, data analyses were needed to account for the ongoing recovery. Hydraulic properties of the Midville aquifer system were estimated by an approach based on the Theis model and superposition. The Midville aquifer system was modeled as a Theis aquifer. The principle of superposition was used to sum the effects of multiple pumping and recovery events from a single pumped well and to sum the effects of all pumped wells as the estimated total drawdown at a monitored well. Simulated drawdown at each monitored well was determined by using a spreadsheet (SUMTheis) function of aquifer transmissivity and storativity. Simulated drawdown values were transformed into simulated water levels, accounting for longterm water-level trends. The transmissivity and storativity values that were used to calibrate the simulated water levels to measured water levels (roughly 4,000 square feet per day and 2E-04, respectively) provide estimates of the transmissivity and storativity of the Midville aquifer system in the vicinity of Well Field 2.

  9. Future USA development

    The planning for further development in the USA at this time is a mixture of expectation and guessing. Modeling development is certain to continue, but the target reactor is uncertain. The next plant may or may not use the FFTR driver fuel design. The planning, therefore, emphasizes fundamentals and flexibility. There are many options to be modeled. The FFTF driver fuel performance in FFTF must be evaluated; both the reference and improved designs. A decision to use the FFTR driver design in the large plant will demand predictions on the effects of axial blankets, constant power (rather than decreasing) throughout life, and power changes, behavior beyond breach and design basis transients in large plants. A decision favoring a lower doubling time oxide design adds the effects of higher strength/lower swelling alloys, increased pin diameter, reduced cladding thickness/diameter, increased smeared density, gap versus pellet density, and reduced pin pitch/diameter. A helium bonded carbide design adds concern about increased potential for fuel-cladding-assembly mechanical interactions. And blanket pin performance predictions, either in a homogeneous or a heterogeneous core, add an increasing power history and enhanced assembly interactions. It is possible that the decision will be to choose a first core and retain all options for later cores. The modeling objective, for whatever options are chosen, is to predict the effect of normal and off-normal design conditions on performance limits (i.e., fuel temperature, pin deformation, pin lifetime). Several significant uncertainties in the mechanisms associated with the performance limits remain and will be addressed. These include gap closure, gap conductance and fuel properties at higher burnup, fuel-fission product reactions, retained gas, breach mechanisms, assembly interactions and behavior beyond breach, plus establishing appropriate criteria. The LIFE system, with its elements of 1D and 2D fundamental modeling

  11. Dengue in Florida (USA

    Jorge R. Rey


    Full Text Available Florida (USA, particularly the southern portion of the State, is in a precarious situation concerning arboviral diseases. The geographic location, climate, lifestyle, and the volume of travel and commerce are all conducive to arbovirus transmission. During the last decades, imported dengue cases have been regularly recorded in Florida, and the recent re-emergence of dengue as a major public health concern in the Americas has been accompanied by a steady increase in the number of imported cases. In 2009, there were 28 cases of locally transmitted dengue in Key West, and in 2010, 65 cases were reported. Local transmission was also reported in Martin County in 2013 (29 cases, and isolated locally transmitted cases were also reported from other counties in the last five years. Dengue control and prevention in the future will require close cooperation between mosquito control and public health agencies, citizens, community and government agencies, and medical professionals to reduce populations of the vectors and to condition citizens and visitors to take personal protection measures that minimize bites by infected mosquitoes.

  18. Reprocessing (1): Barnwell, USA

    The matter discussed is whether the US Administration will allow a large reprocessing plant, located in a South Carolina forest, to start operations. Constructed by private industry at a cost so far of some 250 million dollars, this facility could become either a key component in the US nuclear power programme, or a massively expensive white elephant. Designed as the first full-scale commercial plant to reprocess spent fuel from power reactors, the facility is falling victim to rising concerns about the proliferation of nuclear weapons, and its fate will probably hang on a complex series of regulatory, political and diplomatic decisions expected to be taken in the near future. Even if the Administration decides to allow the plant to start operations, however, its problems will not be entirely over. Before it can operate at full capacity additional facilities to solidify highly active wastes from the plant and to convert Pu nitrate to oxide will be required, estimated to cost 500 million dollars, a sum that private industry says it is unwilling to risk without government assistance. The plant is designed to reprocess fuel continuously from about 50 commercial power reactors, extracting Pu and U and recycling the materials as new reactor fuel. Activities of environmental and anti-nuclear groups with regard to large scale Pu production are discussed, together with the findings of the US Nuclear Regulatory Commission, including the holding of public hearings. Political developments are also discussed, including the establishment of international controls. The conclusion is reached that the future for reprocessing in the USA is uncertain. (U.K.)

  1. FERMILAB: Main Injector

    The Fermilab Main Injector (FMI) project is the centerpiece of the Laboratory's Fermilab III programme for the 1990s. Designed to support a luminosity of at least 5x1031 cm-2 s-1 in the Tevatron collider, it will also provide new capabilities for rare neutral kaon decay and neutrino oscillation studies. The Fermilab Main Injector 8-150 GeV synchrotron is designed to replace the existing Main Ring which seriously limits beam intensities for the Tevatron and the antiproton production target. The project has passed several significant milestones and is now proceeding rapidly towards construction. The project received a $11.65M appropriation in 1992 and has been given $15M for the current fiscal year. Through the Energy Systems Acquisition Advisory Board (ESAAB) process, the US Department of Energy (DoE) has authorized funds for construction of the underground enclosure and service building where the Main Injector will touch the Tevatron, and to the preparation of bids for remaining project construction

  10. Nuclear rockets in USA and the former USSR

    This document is a result of review work on nuclear rockets which had been developed in USA and the former USSR, which was conducted under the theme 'Study of Very Small Reactors' in the Japan Atomic Energy Research Institute. The investigation depended mainly on the proceedings of annual series (1983-1994) of Symposium on Space Nuclear Power Systems held at Albuquerque, New Mexico, USA. The history of nuclear rocket development in USA can be divided into two periods. The first period was 1955-1973 when the NERVA/Rover program was extensively developed. The second period was 1983-1993 or 4, when the SP-100 program and the SEI program were the main activities in USA. In this period, the manned Mars mission using nuclear thermal rocket was enthusiastically discussed in addition to the development of 100kWe space nuclear power source. Therefore, this document contains the essential technological fruits in the first period and the conceptual designs or studies and engineering developments in the second period. The space nuclear technology developments in the former USSR cannot be divided in the same manner. The descriptions on the development in this country are focused on the TOPAZ-2 which had already been developed as a 6kWe space nuclear power source and tested two times on the low earth orbit.

  17. The main players

    About 30 French main players in the field of energy (political parties, administrations, companies, non-governmental organizations and think-tanks) have been reported and dispatched on a chart according to their opinions following 2 axis: pro- versus anti-nuclear energy and pro- versus anti-wind power. The energy sector in France is dominated by 4 companies: EDF, GDF-Suez, Areva and Total, all are strongly pro-nuclear. All the political parties except EELV (Europe-Ecology-Les-Verts) are favourable to nuclear energy. Most non-governmental organizations are favourable to renewable energies, but the FED (Federation Environnement Durable) gathers local associations fighting the installations of wind turbines. (A.C)

  18. TRIGA reactor main systems

    This module describes the main systems of low power (<2 MW) and higher power (≥2 MW) TRIGA reactors. The most significant difference between the two is that forced reactor cooling and an emergency core cooling system are generally required for the higher power TRIGA reactors. However, those TRIGA reactors that are designed to be operated above 3 MW also use a TRIGA fuel that is specifically designed for those higher power outputs (3 to 14 MW). Typical values are given for the respective systems although each TRIGA facility will have unique characteristics that may only be determined by the experienced facility operators. Due to the inherent wide scope of these research reactor facilities construction and missions, this training module covers those systems found at most operating TRIGA reactor facilities but may also discuss non-standard equipment that was found to be operationally useful although not necessarily required.

  19. Main Oxidizer Valve Design

    Addona, Brad; Eddleman, David


    A developmental Main Oxidizer Valve (MOV) was designed by NASA-MSFC using additive manufacturing processes. The MOV is a pneumatically actuated poppet valve to control the flow of liquid oxygen to an engine's injector. A compression spring is used to return the valve to the closed state when pneumatic pressure is removed from the valve. The valve internal parts are cylindrical in shape, which lends itself to traditional lathe and milling operations. However, the valve body represents a complicated shape and contains the majority of the mass of the valve. Additive manufacturing techniques were used to produce a part that optimized mass and allowed for design features not practical with traditional machining processes.

  20. Abstracts of Main Essays

    Feng Zi-yi


    On Deepening the Research on the Law of the Social Horizontal Development Feng Zi-yi The further development of globalization makes it urgent to deepen the research on the law of social hori- zontal development. Historical development of human society has experienced periods of isolation, multi-cen- ter, and globalization, while the truly horizontal development began from modernity. This kind of development is driven mainly by the logic of capital. The transforming process of capital, from dominating the whole process of economic development toward all aspects of social life, and from dominating nations toward the whole world, is also the logical process of capital pursuing itself and the process of social horizontal and wholly development as well. Horizontal and vertical developments of the society are interacting always. Researching on the law of social horizontal development is important for us to adapt to the historical trend consciously, to grasp the logic of capital rationally and to choose the right road of development.

  4. About the treaty of complete nuclear test ban: the USA between unilateralism and multilateralism

    This article analyses the possible reasons that have led the US Senate to reject the treaty of comprehensive nuclear test ban. Even if this decision did not retained the attention of the international public opinion, it appears as surprising because the USA have worked a lot for the elaboration of this treaty and were considered as the main beneficiaries of it. Three interpretations are proposed by the author: some purely internal disputes inside Clinton's administration, a real will of the USA to abandon the arms control policy, or an intermediate attitude which allows the USA to act on different levels and to get rid of common rules.

  9. Forensic entomology and main challenges in Brazil.

    Gomes, Leonardo; Von Zuben, Cláudio J


    Apart from an early case report from China (13th century), the first observations on insects and other arthropods as forensic indicators were documented in Germany and France during mass exhumations in the 1880s by Reinhard, who is considered a co-founder of the discipline. After the French publication of Mégnin's popular book on the applied aspects of forensic entomology, the concept quickly spread to Canada and United States. At that time, researchers recognized that the lack of systematic observations of insects of forensic importance jeopardized their use as indicators of postmortem interval. General advances in insect taxonomy and ecology helped to fill this gap over the following decades. After World Wars, few forensic entomology cases were reported in the scientific literature. From 1960s to the 1980s, Leclercq and Nuorteva were primarily responsible for maintaining the method in Central Europe, reporting isolated cases. Since then, basic research in the USA, Russia and Canada opened the way to the routine use of Entomology in forensic investigations. Identifications of insects associated with human cadavers are relatively few in the literature of the Neotropical region and have received little attention in Brazil. This article brings an overview of historic developments in this field, the recent studies and the main problems and challenges in South America and mainly in Brazil. PMID:17352063

  17. Comments on the energy crises of the USA. Pt. 2

    Various alternatives to reduce the energy crisis, up to the radical solution of 'zero-growth' are now under discussion and the consequences are being discussed in Congress and in the press of the USA. For the next 30 to 50 years, the USA economy will be based mainly on fossil fuels. A development of the plants for coal liquefaction is necessary within the next 10 years. An increased use of breeder reactors is necessary in order to stretch the existing uranium reserves. Research and development in the field of nuclear fusion should be accelerated especially regarding the generation of cheap hydrogen by electrolysis of sea-water. Increased use of geothermal and solar energy, as well as of water and wind power could support the energy programme. (HW)

  1. China / USA - Climate at stake; Chine / USA - Le climat en jeu

    Marechal, Jean-Paul


    Climate change is one of the major challenge that humanity will have to take up during the coming decades. The preparation in 2012 of the 'post-Kyoto' era, where all countries would take up their climate responsibilities, remains the hardest trial. However, all successive international summits did not lead to any constraining agreement between countries. The main reason is the rivalry and dependence relation which links China and the USA. It is now obvious that no major climate decision can be taken without the double determined commitment of these both giants, and so far it is not in their interest to lead by example. This book analyses the freeze of this situation in an historical perspective and identifies some paths of solution to this serious problem. (J.S.)

  2. Green electricity - experiences from USA; Groen el - erfarenheter fraan USA

    Graens, N.


    Environmental concern has opened a market for electric power produced from renewable energy sources in USA. A number of American electric utilities have responded to the interest from the public and offered green electricity at a price somewhat above the normal rates. Most of these programs, that have existed for a few years, have succeeded quite well, giving the utilities better relations to their customers and experiences from marketing new products. The customers have been satisfied and shown enthusiasm for the new product. The present report reviews the attitudes to and drive behind green electricity from/relative to utilities, customers, environmental organizations and authorities. The programs and experiences of the utilities are described, and the prospects for green power on a deregulated market are discussed. Speculations about market responses to green power in Sweden are also made. 37 refs, 13 figs

  12. Modelling middle pliocene warm climates of the USA

    Haywood, A.M.; Valdes, P.J.; Sellwood, B.W.; Kaplan, J.O.; Dowsett, H.J.


    The middle Pliocene warm period represents a unique time slice in which to model and understand climatic processes operating under a warm climatic regime. Palaeoclimatic model simulations, focussed on the United States of America (USA), for the middle Pliocene (ca 3 Ma) were generated using the USGS PRISM2 2?? ?? 2?? data set of boundary conditions and the UK Meteorological Office's HadAMS General Circulation Model (GCM). Model results suggest that conditions in the USA during the middle Pliocene can be characterised as annually warmer (by 2?? to 4??C), less seasonal, wetter (by a maximum of 4 to 8 mm/day) and with an absence of freezing winters over the central and southern Great Plains. A sensitivity experiment suggests that the main forcing mechanisms for surface temperature changes in near coastal areas are the imposed Pliocene sea surface temperatures (SST's). In interior regions, reduced Northern Hemisphere terrestrial ice, combined with less snow cover and a reduction in the elevation of the western cordillera of North America, generate atmospheric circulation changes and positive albedo feedbacks that raise surface temperatures. A complex set of climatic feedback mechanisms cause an enhancement of the hydrological cycle magnifying the moisture bearing westerly wind belt during the winter season (Dec., Jan., Feb.). Predictions produced by the model are in broad agreement with available geological evidence. However, the GCM appears to underestimate precipitation levels in the interior and central regions of the southern USA. Copyright: Palaeontological Association, 22 June 2001.

  13. Experience from Soybean Industry Development of Main Soybean Producing Countries

    MA Zenglin; GUO Xiangyu


    Soybean output and trade are mainly operated in America, Brazil, Argentina and China in recent years, especially in America. For China, the import output is number one, and the export output is the forth. For this reason, the soybean industry of China got a huge lash, and the soybean farmers got a large loss, it influenced the building of new countryside construction in China. Both U.S.A's soybean output and trade amout are the number one in the world, this achievement should be contributed to U.S.A's advanced production ability and its favorable subsidy policies. Contrary to U.S.A's large subsidy and cheap loan, Brazil and Argentina raise their soybean output and trade amount by high production technology and "untying" policies, such as abolishing some unreasonable rules and tax. So if we want to develop Chinese soybean industry and make sure our soybean industry's safety, it's necessary for us to experience soybean industry development of other countries' and improve ours.

  15. Licensing reform in the USA

    The licensing process for nuclear power plants in the USA is currently in two distinct stages: the issuance of a construction permit followed later by the issuance of an operation license. The ''two-step'' process has come under heavy criticism from the U.S. nuclear industry on the grounds that it causes uncertainty and delays and therefore inhibits new commitments to nuclear power plants. In 1989 the NRC published new regulations for the licensing of nuclear power plants which provide for the issuance of early site permits, safety certifications of standard designs, and combined construction permits and operating licences. The new rule was challenged by intervenors representing antinuclear groups who filed a legal challenge seeking to have the rule set aside on the grounds that it violates the Atomic Energy Act which they allege makes two-step licensing mandatory. In November 1990 the US Court of Appeals upheld the NRC's authority to issue combined licenses. An appeal for a rehearing has been filed. The paper analyses the events and the possible consequences of an adverse court decision. It reviews the options open to the NRC and industry if the court decision is upheld. The possibility of congressional action to amend the Atomic Energy Act is discussed. (author)

  9. Environmental radon and cancer correlations in Maine.

    Hess, C T; Weiffenbach, C V; Norton, S A


    The distribution of 222Rn has been measured in the sixteen counties of Maine, U.S.A. by liquid scintillation counting of water samples from more than two thousand public and private wells. Three hundred and fifty of these wells have been characterized for geology and hydrology. Airborne radon has been measured in seventy houses with grab samples and in eighteen houses for 5-7 days each with continuously recording diffusion-electrostatic radon detectors. Concentrations of radon in water ranged from 20 to 180,000 pCi/l. Granite areas yielded the highest average levels (mean = 22,100 pCi/l.; n = 136), with considerable intra-granite variation. Metasedimentary rocks yielded levels characteristic of the lithology for metamorphic grades ranging from chlorite to andalusite. Sillimanite and higher-grade rocks yielded higher 222Rn levels, probably due to the intrusion of uranium-bearing pegmatites in these terranes. Airborne 222Rn in homes ranged from 0.05 to 210 pCi/l. At the high end of this range, doses will exceed recommended industrial limits. In some homes only a small fraction of the airborne 222Rn was due to the water supply. Average 222Rn levels in domestic water supplies for each of the 16 counties, calculated by areally averaging rock types and their associated 222Rn levels, were found to be significantly correlated with rates for all cancers combined and rates for lung and reproductive cancers in the counties. Although numerous factors other than cancer induction by indoor daughter exposures may be responsible for the observed correlations, these have not been investigated in detail. PMID:6885433

  13. I-WARP: Individual Water mAin Renewal Planner

    Y. Kleiner


    Full Text Available I-WARP is based upon a nonhomogeneous Poisson approach to model breakage rates in individual water mains. The structural deterioration of water mains and their subsequent failure are affected by many factors, both static (e.g., pipe material, pipe size, age (vintage, soil type and dynamic (e.g., climate, cathodic protection, pressure zone changes. I-WARP allows for the consideration of both static and dynamic factors in the statistical analysis of historical breakage patterns. This paper describes the mathematical approach and demonstrates its application with the help of a case study. The research project within which I-WARP was developed, was jointly funded by the National Research Council of Canada (NRC, and the Water Research foundation (formerly known as the American Water Works Association Research Foundation – AwwaRF and supported by water utilities from USA and Canada.

  15. Quebec-USA electricity export contracts

    Electricity exports from Hydro-Quebec to utilities in the USA significantly affects the economy and environment of Quebec. These exports may be arranged under interconnection agreements to sell excess capacity and production during off-peak periods or under firm sales contracts. Hydro-Quebec exports could also replace power plants that would otherwise be needed in the USA. The economic environment for Hydro-Quebec exports to the USA is reviewed along with the regulatory environment applicable to international trade (General Agreement on Tariffs and Trade, Canada-USA Free Trade Agreement, North American Free Trade Agreement), Quebec (Canadian federal and provincial law), and the USA (federal and state law). A jurisdictional analysis of power export contracts is then presented, citing examples of contracts already signed by Hydro-Quebec with utilities in New York and New England. Contract law and contract provisions are discussed, including common clauses and particular clauses. Suggestions are made for new clauses that would improve the electricity trade. 215 refs., 13 figs., 3 tabs

  20. Creating markets for air pollution control in Europe and the USA

    This paper surveys recent efforts to relax the rigid regulatory frameworks for air pollution control in Europe and the USA. European policies have mainly taken the form of bubbles and compensation or offset schemes. Emission trading has been limited to intra-firm solutions for various reasons: industry structure, absence of real scarcity, and too restrictive trading rules. Bubbles have been granted to homogenous sectors only and can be characterized as direct regulation for a group rather than tradeable permit systems. By contrast, the sulphur allowance program in the USA has laid down the foundation for a pollution permit market with few formal restrictions. Problems that arise arc mainly related to local environmental and public utility controls. Europe can learn from the USA that regular national permit markets could be installed, preferably for homogenous sectors. In designing the permit system, the differences between the USA and Europe in terms of ecosystem sensitively, stringency of regulation and differentiation of regional environmental policy have to be taken into account. 1 fig., 2 tabs., 54 refs

  2. The USA: Challenges of the Superpower

    Dr. Ketevan Rostiashvili


    Full Text Available Since the collapse of the Soviet Union function and mission of the United States in the contemporary world system is one of the most debatable problems of academic litera-ture. This article is an attempt to analyze most recent socioeconomic and political tendencies of the USA for better understanding the scale of ongoing transformation of the society. As the level of integration of contemporary world is very high, transfor-mation of the USA provokes tectonic changes and transformation of the world system, its structure and nature. This study argues that, although the US primacy in the world is significantly challenged and shaken by external and internal factors, the USA still preserves its traditional function of economic, financial, military and political superpow-er, but in a quite different environment. The article predominantly uses materials drawn from the Central Intelligence Agency (CIA, The World Fact book 2012; U.S. Census Bureau, Statistical Abstract of the USA - 2012, the US Federal Budgets 2010-2012, and other valuable literature and sources.

  13. The main Aeromonas pathogenic factors.

    Tomás, J M


    The members of the Aeromonas genus are ubiquitous, water-borne bacteria. They have been isolated from marine waters, rivers, lakes, swamps, sediments, chlorine water, water distribution systems, drinking water and residual waters; different types of food, such as meat, fish, seafood, vegetables, and processed foods. Aeromonas strains are predominantly pathogenic to poikilothermic animals, and the mesophilic strains are emerging as important pathogens in humans, causing a variety of extraintestinal and systemic infections as well as gastrointestinal infections. The most commonly described disease caused by Aeromonas is the gastroenteritis; however, no adequate animal model is available to reproduce this illness caused by Aeromonas. The main pathogenic factors associated with Aeromonas are: surface polysaccharides (capsule, lipopolysaccharide, and glucan), S-layers, iron-binding systems, exotoxins and extracellular enzymes, secretion systems, fimbriae and other nonfilamentous adhesins, motility and flagella.

    Full Text Available Based on the usage of multiple sources of literature in this paper, a review of the most important characteristics is made along with the comparison of functions related to agricultural insurance in Croatia. Larger part of this paper is about comparison of offers and the ways agricultural insurance is being subsided in developed countries of the EU and USA on one hand, and Croatia on the other. Also, a display of risk coverage is made, along with the subsidization of the country and the way insurance system functions in Spain (country with the most developed security in Europe, Portugal, Italy, Austria and France. Main characteristic of the agricultural insurance in Croatia is a weak offer from the insurance companies, but also a weak demand. Therefore, only four companies can insure crops and plantations in Croatia. Although risk is unavoidable, negative impacts can be reduced with well-timed reaction and responsible organisation.

  16. Main injector synchronous timing system

    The Synchronous Timing System is designed to provide sub-nanosecond timing to instrumentation during the acceleration of particles in the Main Injector. Increased energy of the beam particles leads to a small but significant increase in speed, reducing the time it takes to complete a full turn of the ring by 61 nanoseconds (or more than 3 rf buckets). In contrast, the reference signal, used to trigger instrumentation and transmitted over a cable, has a constant group delay. This difference leads to a phase slip during the ramp and prevents instrumentation such as dampers from properly operating without additional measures. The Synchronous Timing System corrects for this phase slip as well as signal propagation time changes due to temperature variations. A module at the LLRF system uses a 1.2 Gbit/s G-Link chip to transmit the rf clock and digital data (e.g. the current frequency) over a single mode fiber around the ring. Fiber optic couplers at service buildings split off part of this signal for a local module which reconstructs a synchronous beam reference signal. This paper describes the background, design and expected performance of the Synchronous Timing System

  17. Main Dangers of Our Times.

    Synek, Miroslav


    Terrorism and threatening dictatorships are the main, man-made, dangers of our times. They are run by master demagogues, or, brain-washing manipulators. ----- Our next step in coping with terrorism is to counter master demagoguery. Therefore, supporting EDUCATION that would emphasize the most unifying (and the least controversial), yet, BASIC CIVIC RESPECT for lives of people in a civilian human society, is a priority everywhere on our planet. ----- At the same time we start facing mostly small, threatening, dictatorships, capable of producing weapons of mass destruction. Therefore, we have to try to contribute to developing systems of FREE ELECTIONS, controlling weapons of mass destruction, wherever such dangers exist. ----- In a foreseeable future, unfortunately, we are facing a danger even by orders of magnitude greater. We are facing a possibility of a mass-produced heavy accumulation of inter-continental nuclear missiles, on a computerized "push-button" control, by a very powerful (and, quite possibly, miscalculating, or, suicidal) dictator, dangerous to the very existence of humanity on our planet. Therefore, it is a historical urgency that such a technological power be under the control by a government of the people, by the people and for the people, based on a sufficiently reliable system of FREE ELECTIONS, wherever, on our planet, such a potential danger may originate.

  5. Impact of the development of shale gases in the USA on the European petrochemical industry

    As the massive development of shale gases and oils in the USA is often only considered in its energetic dimension, the author discusses the influence these raw materials have, not only on energy production, but as raw materials for the industry and more particularly for the petrochemical industry which is a high energy consumer and also transforms these products into products used by all types of manufacturing industries. In a first part, the author recalls this strong development of shale gas production in the USA, its main impacts on the US gas industry, notably its impact on energy prices on the American market. In a second part, the author reports the analysis of the contrasted evolutions of energy prices (gas, electricity, ethane, naphtha) in the USA and in Europe, and highlights the significant competitive advantage the USA took from the development of shale gas. A third part describes the revival of the American petrochemical industry through numerous investment projects of new ethylene and polyethylene production capacities which have been announced since the decrease of energy prices. The impact of this development on the European petrochemical industry is analysed in the next part which also describes adaptation strategies adopted by European petrochemical industries

  6. Origins and Formation of Corporate Education in the USA

    Lytovchenko Iryna


    Full Text Available The article analyzes the process of formation and development of corporate education in the USA in the first half of the twentieth century. It has been determined that the main prerequisites for the development of corporate education in the USA in the first half of the twentieth century were historical, socio-economic, political factors and advances in scientific research including: the rapid growth of the US economy in the twentieth century; dissemination of scientific and technological progress and constant introduction of new technologies in the workplace; a national policy of “welfarism”; scientific works of R. Kelly “Training industrial workers” and D. Morris “Employee training: A study of education and training departments in various corporations”, which contained the first complex researches on training in industry, substantiated the necessity and prospects of this study, analyzed corporate programs of that time, the ideas on scientific management of F. Taylor, F. Gilbreth and S. Thompson, which had a major impact on all business areas. It has been found out that corporate education was the result of evolution of apprenticeship, the oldest and most traditional form of vocational training in the United States. By 1920s a new concept of modern education had been formed in the workplace which had its philosophical foundations, educational programs, technologies, system of providing services and organizational structure. In the period between the First and Second World Wars a new vision of learning at the workplace arose, new teaching methods were developed different from those used in traditional educational institutions; understanding came that the dissemination of knowledge within the whole community would contribute to building a democratic society.

  7. Transuranic radioactive (TRU) waste management in the USA

    In the United States of America (USA), the US Department of Energy (DOE) is responsible for the safe management and disposal of all transuranic radioactive (TRU) waste. Based on the promising characteristics of the 225-million-year-old stable sequence of evaporitic rocks (mainly rock salt) at the Waste Isolation Pilot Plant (WIPP) site, an underground test facility was developed in the early 1980s at a depth of approximately 655 meters in the candidate host salt formation. In 1994, after more than 20 years of characterizing and evaluating the WIPP site, the DOE concluded that available data and long-term performance assessments (PAs) strongly indicated the WIPP site exhibits very suitable natural characteristics for hosting a deep geologic disposal facility (repository) for TRU waste. In April 1994, the DOE Carlsbad Area Office (CAO) presented a new strategy and an accelerated schedule targeting June 1998 for the opening of a TRU waste repository at the WIPP site. The main objectives of this strategy are to: resolve regulatory compliance and technical issues; characterize the waste; address transportation and safety issues; and involve stakeholders (interested parties) in the regulatory compliance process

  8. Development of Teachers’ Alternative Certification in the USA

    Pazyura Natalia


    Full Text Available The article reveals the prerequisites of appearance of alternative ways to train teachers in the USA at the end of the XX century as main mechanisms to increase qualitative and quantitative characteristics of teaching staff. The author concentrates the attention on the advantages and disadvantages of non-traditional ways to acquire teaching profession. The peculiarities of the development in different states of the country, main characteristics of the training with the help of alternative programs have been found as well as the target groups have been described. Such research is clearly needed, both by policymakers and by practitioners, to determine the appropriateness of alternative certification training models in training educators to deliver quality educational programming to students, as well as their effectiveness in addressing the critical teacher shortages by increasing the pool of available teachers and reducing the turnover and retention problems. Proponents of alternative certification have asserted that such models encourage talented people from other fields to enter teaching and increase the potential supply of teachers available to reduce shortages, and that traditional teacher education programs have little substance or value in training teachers while alternative models provide intensive training and supervision focused on critical skills needed for successful teaching.
