    1981-01-01

    The stress corrosion cracking resistance of high strength, wrought aluminum alloys in a seacoast atmosphere was investigated and the results were compared with those obtained in laboratory tests. Round tensile specimens taken from the short transverse grain direction of aluminum plate and stressed up to 100 percent of their yield strengths were exposed to the seacoast and to alternate immersion in salt water and synthetic seawater. Maximum exposure periods of one year at the seacoast, 0.3 or 0.7 of a month for alternate immersion in salt water, and three months for synthetic seawater were indicated for aluminum alloys to avoid false indications of stress corrosion cracking failure resulting from pitting. Correlation of the results was very good among the three test media using the selected exposure periods. It is concluded that either of the laboratory test media is suitable for evaluating the stress corrosion cracking performance of aluminum alloys in seacoast atmosphere.

  3. Self-stabilized Fractality of Sea-coasts Through Damped Erosion

    Coastline morphology is of current interest in geophysical research and coastline erosion has important economic consequences. At the same time, although the geometry of seacoasts is often used as an introductory archetype of fractal morphology in nature there has been no explanation about which physical mechanism could justify that empirical observation. The present work propose a minimal, but robust, model of evolution of rocky coasts towards fractality. The model describes how a stationary fractal geometry arises spontaneously from the mutual self-stabilization of a rocky coast morphology and sea eroding power. If, on one hand, erosion generally increases the geometrical irregularity of the coast, on the other hand this increase creates a stronger damping of the sea and a consequent diminution of its eroding power. The increased damping argument relies on the studies of fractal acoustical cavities, which have shown that viscous damping is augmented on a longer, irregular, surface. A minimal two-dimensional model of erosion is introduced which leads to the through a complex dynamics of the earth-sea interface, to the appearance of a stationary fractal seacoast with dimension close to 4/3. Fractal geometry plays here the role of a morphological attractor directly related to percolation geometry. The model reproduces at least qualitatively some of the features of real coasts using only simple ingredients: the randomness of the lithology and the decrease of the erosion power of the sea. B.

    Full Text Available Recreational architecture is a branch of architectural activity whose main object is formation of recreational spaces (territories, buildings, complexes and equipment. The goal of recreational architecture is to create optimal (comfortable, lovely and realizable environment for all recreation types and forms. This goal is realized by projects which are based on scientific research and recommendations. This activity needs more than casual work and living environment. It needs special space and equipment: territory, water area, buildings, and rooms. Everything can be called recreational environment. Recreational environment can be of various dimensional scales: enormous seaside or lake areas intended for recreation, resorts, recreational institution complexes and many single buildings, beaches, forest parks, pools. Recreational environment is possible not only out of town but in town as well. Beginning of recreational architecture is observed in antique cultures, but as a separate specific architectural activity branch it rapidly began to spread in last century first half and in Lithuania – in the last four decades. In this work, analysis of evaluating recreational architecture is made seeking to reveal recreational architecture evaluating criteria and their use .Article in Lithuanian

  14. Corrosion Performance of New Generation Aluminum-Lithium Alloys for Aerospace Applications

    Science.gov (United States)

    Moran, James P.; Bovard, Francine S.; Chrzan, James D.; Vandenburgh, Peter

    Over the past several years, a new generation of aluminum-lithium alloys has been developed. These alloys are characterized by excellent strength, low density, and high modulus of elasticity and are therefore of interest for lightweight structural materials applications particularly for construction of current and future aircraft. These new alloys have also demonstrated significant improvements in corrosion resistance when compared with the legacy and incumbent alloys. This paper documents the superior corrosion resistance of the current commercial tempers of these materials and also discusses the corrosion performance as a function of the degree of artificial aging. Results from laboratory corrosion tests are compared with results from exposures in a seacoast atmosphere to assess the predictive capability of the laboratory tests. The correlations that have been developed between the laboratory tests and the seacoast exposures provide confidence that a set of available methods can provide an accurate assessment of the corrosion performance of this new generation of alloys.

    Higgins, R. H.

    1981-01-01

    A study of several protective coating systems for use on aluminum in seawater/seacoast environments was conducted to review the developments made on protective coatings since early in the Space Shuttle program and to perform comparative studies on these coatings to determine their effectiveness for providing corrosion protection during exposure to seawater/seacoast environments. Panels of 2219-T87 aluminum were coated with 21 different systems and exposed to a 5 percent salt spray for 4000 hr. Application properties, adhesion measurements, heat resistance and corrosion protection were evaluated. For comparative studies, the presently specified Bostik epoxy system used on the SRB structures was included. Results of these tests indicate four systems with outstanding performance and four additional systems with protection almost as good. These systems are based on a chromated pretreatment, a chromate epoxy primer, and a polyurethane topcoat. Consideration for one of these systems should be included for those applications where superior corrosion protection for aluminum surfaces is required.

    Swimming is unnatural activity for human beings. Unlike most of all other animals, we are not born with an instinct for swimming. However, ancient peoples who settled along seacoasts, lakeshores, and riverfronts had to learn to swim for gathering food and for simple survival. From this necessity, recreational swimming would have developed, both as an activity for individuals and as a group social practice. In many ancient civilizations, communal swimming and, later, bathing rituals were an in...

    The urbanization effects and their possible causes on the environmental gamma radiation levels, in an anomalous area, were studied. The field work was accomplished in Guarapari, located in the seacoast of the Brazilian state of Espirito Santo, which is rich in monazite sands, with thorium and uranium contents. The results show clearly that there was a reduction in the levels of external exposition in the streets and squares of Guarapari. It was ascertained that the reduction was due to the materials used in the urbanization. (L.C.J.A.)

    Fine and coarse particles have been sampled from 1982 to 1985 in one natural forest seacoast site (Jureia) and five urban-industrial cities (Vitoria, Salvador, Porto Alegre, Sao Paulo, and Belo Horizonte). The time variations of concentrations in air and the relative elemental compositions of fine and coarse particle fractions, sampled by Nuclepore stacked filter units (SFU), have been determined gravimetrically and by PIXE analysis, respectively. Enrichment factors and correlation coefficients of the trace elements measured lead to unambiguous characterization of soil dust and sea salt, both major aerosol sources that emit coarse particles, and soil dust is also a significant source of fine particles.

    1980-01-01

    The resistance of the martensitic precipitation hardening stainless steels PH13-8Mo, 15-5PH, and 17-4PH to stress corrosion cracking was investigated. Round tensile and c-ring type specimens taken from several heats of the three alloys were stressed up to 100 percent of their yield strengths and exposed to alternate immersion in salt water, to salt spray, and to a seacoast environment. The results indicate that 15-5PH is highly resistant to stress corrosion cracking in conditions H1000 and H1050 and is moderately resistant in condition H900. The stress corrosion cracking resistance of PH13-8Mo and 17-4PH stainless steels in conditions H1000 and H1050 was sensitive to mill heats and ranged from low to high among the several heats included in the tests. Based on a comparison with data from seacoast environmental tests, it is apparent that alternate immersion in 3.5 percent salt water is not a suitable medium for accelerated stress corrosion testing of these pH stainless steels.

  4. Problems in Siting Nuclear Power Plants in Japan and Efforts to Solve Them

    Energy Technology Data Exchange (ETDEWEB)

    Inouye, T. [Ministry of International Trade and Industry, Tokyo (Japan)

    1967-09-15

    The rapidly growing demand for energy in Japan will require a total capacity of 30 to 40 thousand MW(e) in nuclear power by 1985. Materialization of this development programme must naturally be supported by securing the requisite sites for the nuclear power plants. The following factors make siting of nuclear power plants more difficult in Japan than in any other country: a small, densely populated territory with little level land, that is already completely utilized for agricultural and/or industrial purposes; small rivers and an active marine-product industry developed along most of the seacoasts, both of which create difficult cooling-water problems; frequent earthquakes; and the fear of possible radioactivity, which prevails in the only nation in the world to have suffered from the atomic bomb. There are at present four nuclear power plants in operation or under construction in Japan with a total capacity of about 1.3 thousand MW(e). However, the plants in these construction programmes have been sited on the basis of taking the easiest course available although there were several possible solutions to choose from. It is pointed out here that the long-range nuclear power development programme will call for a fundamental solution to enable siting a large number of power plants under the adverse conditions in Japan. Accordingly, a study was made, which included quantitative analyses of reactor siting factors and suggested measures for solving the siting problems. The analyses were based on nuclear power plant sites assumed to be located on the seacoast and characterized by low-population density, desirable geology and favourable topography. It was assumed that seacoast siting was more economical than inland siting. Although the study was made by a general survey using maps, it was shown that approximately 10% of the total coastline areas would be eligible for reactor siting, but most of these areas in this case are located in the northern part of Japan, far from

    The Materials Monitoring Facility is equipped with an exhaust stack to emit air from a controlled area (the hot laboratory) into the atmosphere. Cracks and exfoliation have been observed for the surface of the exhaust stack, which is made of reinforced concrete and was constructed on the seacoast about 25 years ago, so exposed to a salt-corrosive condition. In order to get details of the present condition of the exhaust stack, an inspection was carried out using an electromagnetic wave radar method and chloride content method. Cracks and exfoliation were observed for the whole stack surface, especially for high positions. Moreover, salt damage was observed for the outer surface of the exhaust stack, and it was estimated that the infiltration of the chloride content was about 17 mm. Based on this detailed inspection of the exhaust stack, maintenance and repair work were carried out. (author)

  7. Kinetic model for predicting the concentrations of active halogen species in chlorinated saline cooling waters

    International Nuclear Information System (INIS)

    Lietzke, M.H.; Haag, W.R.

    1979-01-01

    A kinetic model for predicting the composition of chlorinated water discharged from power plants using fresh water for cooling was previously reported. The model has now been extended to be applicable to power plants located on estuaries or on the seacoast where saline water is used for cooling purposes. When chloride is added to seawater to prevent biofouling in cooling systems, bromine is liberated. Since this reaction proceeds at a finite rate there is a competition between the bromine (i.e., hypobromous acid) and the added chlorine (i.e., hypochlorous acid) for halogenation of any amine species present in the water. Hence not only chloramines but also bromamines and bromochloramines will be formed, with the relative concentrations a function of the pH, temperature, and salinity of the water. The kinetic model takes into account the chemical reactions leading to the formation and disappearance of the more important halamines and hypohalous acids likely to be encountered in chlorinated saline water

    The Nuclear Power Plants use a large quantity of water for the purpose of cooling the turbine condenser. The heated effluents are discharged to aquatic environment by means of once through cooling wherever large water bodies like seacoast or fresh water reservoir are available. The quality of water bodies are important for the growth and biodiversity of aquatic organisms. Several environmental factors like Temperature pH, Dissolved Oxygen have a bearing on the life cycle of aquatic organisms. The paper describes the evaluation of water quality parameters at the two typical sites one on the sea coast (Tarapur) and other at inland site Kaiga and discusses the environmental impact due to discharge to aquatic environment. It is found that the environmental impacts due to both heated effluents and radioactivity are insignificant. The water quality parameters are found to be well within the prescribed standards.

    As the incoming editor of Global Biogeochemical Cycles, I would like to introduce myself and my ideas for the journal to Eos readers and to current and potential GBC authors. I've had a somewhat ``roaming'' scientific evolution, coming from ``straight'' chemistry through hard-rock geochemistry to chemical oceanography, the field in which I did my Ph.D. I taught marine chemistry at Florida State University for a number of years, and developed an interest in ocean/atmosphere interactions and atmospheric chemistry. In 1987 I took on my present job at the Max Planck Institute for Chemistry, in Mainz, Germany, and, after leaving the seacoast, my interests shifted to interactions between the terrestrial biosphere and atmosphere, including the role of vegetation fires. My present focus is on the role of biogenic aerosols and biomass smoke in regulating cloud properties and influencing climate.

    Full Text Available The spotted wing drosophila Drosophila suzukii Matsumura (Diptera: Drosophilidae is an invasive pest originating from Southeast Asia. It was detected for the first time in Europe in 2008 (Spain and Italy and subsequently in other European countries. It is a highly polyphagous pest that infests healthy, ripening fruit and presents a serious threat to fruit production, particularly of soft skinned fruit. In the first half of October 2013, a new fruit fly species was unexpectedly detected in Tephri traps baited with the three-component female-biased attractant BioLure that is regularly used for monitoring the Mediterranean fruit fly Ceratitis capitata Wiedem. (Diptera: Tephritidae in Montenegro. Brief visual inspection identified the new species as the spotted wing drosophila D. suzukii. The pest was first recorded in several localities on the Montenegrin seacoast around Boka Kotor Bay. After the finding, all Drosophila specimens were collected from traps for further laboratory observation. A quick follow-up monitoring of other Tephri traps was carried out within the next few days on the rest of the seacoast (localities from Tivat to Ulcinj. Additionally, Tephri traps were set up around Lake Skadar and in the city of Podgorica, as well as on fresh fruit markets in Podgorica. The results of this preliminary study showed that D. suzukii was present in all surveyed locations and adults were captured until late December. Both sexes were found in traps with BioLure. Our data show that D. suzukii is present in southern parts of Montenegro and there is a serious threat of its further spreading, particularly towards northern parts of the country where the main raspberry and blueberry production is placed. The results also show that Tephri traps baited with BioLure can be used for detection and monitoring of spotted wing drosophila.

    As part of the outreach component for a project involving the detection and analysis of marine debris generated by Super Storm Sandy, The Center for Coastal and Ocean Mapping / Joint Hydrographic Center partnered with The Seacoast Science Center to develop an interactive museum exhibit that engages the public with a touchscreen based game revolving around the detection and identification of marine debris. "A Hurricane Hits Home" is a multi-station touchscreen exhibit geared towards children, and integrates a portion of a historical wooden shipwreck into its physical design. The game invites museum guests to examine a number of coastal regions and harbors in Sandy affected areas. It teaches visitors about modern mapping technology by having them control boats with multibeam sonars and airplanes with lidar sensors. They drag these vehicles around maps to reveal the underlying bathymetry below the satellite photos. They learn the applications and limitations of sonar and lidar by where the vehicles can and cannot collect survey data (e.g. lidar doesn't work in deep water, and the boat can't go in shallow areas). As users collect bathymetry data, they occasionally reveal marine debris objects on the seafloor. Once all the debris objects in a level have been located, the game challenges them to identify them based on their appearance in the bathymetry data. They must compare the simulated bathymetry images of the debris targets to photos of possible objects, and choose the correct matches to achieve a high score. The exhibit opened January 2016 at the Seacoast Science Center in Rye, NH.

    Full Text Available Population dynamics of the Mediterranean fruit fly was studied along Montenegro seacoast. Tephri traps baited with 3 component female-biased attractants were used in 11 different localities to monitor the fruit fly population in commercial citrus orchards, mixed-fruit orchards, and in backyards. From 2008–2010, the earliest captures were recorded no earlier than July. In 2011, the first adult fly was detected in mid-June. Low captures rates were recorded in July and August (below 0.5 flies per trap per day; FTD and peaked from mid-September to the end of October of each year. Our results indicate fluctuation of fly per trap per day depending on dates of inspection and locality, with significant differences in the adult population density. A maximum population was always reached in the area of Budva-Herceg Novi with an FTD of 66.5, 89.5, 71.63, and 24.64 (from 2008–2011 respectively. Fly activity lasts from mid-June/early-July to end December, with distinct seasonal variation in the population.

    Full Text Available Puffer fish poisoning is a common seafood poisoning. The problem is due to tetradotoxin in puffy fish meat. It can be seen in many countries with seacoasts. The problem is resulted from tetradotoxin (TTX in puffer fish meat. This toxin is an important natural toxin. Here, the authors report summary of case reports from Thailand. The authors use standard search engines (PubMed and Thai Index Medicus for searching on the reports on puffer fish poisoning from Thailand. According to this work, there are at least 3 reports on 55 cases of puffer fish poisoning. All cases visit to the physician within 30 min. Focusing on severity, stage 1, 2, 3 and 4 can be seen in 16%, 8%, 4% and 72%, respectively. In the present report, the summary of the cases presenting to the physician at hospital is shown. Of interest, most patients have severe intoxication and the respirator failure is an important problem to be managed. It is clearly shown in the present report that if good respiratory support is done, the full recovery without problem can be derived. It is no doubt that there is no death case in the present series since the present report focuses on the cases that are successfully delivered to the hospital for management.

  14. Sense of place among New England organic farmers and commercial fishermen: How social context shapes identity and environmentally responsible behavior

    Mueller, Anneliese Marie

    Given the prominence of sense of place in new environmental education curricula, this study aims to strengthen the conceptual and empirical foundations of sense of place, and to determine how sense of place may be linked to environmentally responsible behavior. For this study, five commercial fishermen and five organic farmers from the New England Seacoast region participated in a series of in-depth phenomenological interviews and observations. The data was systematically coded in order to allow themes and categories to emerge. The results indicate that aspects of the existing conceptual framework of sense of place, such as place attachment, ecological knowledge, and public involvement, do in fact describe the relationship between people and place. However, the results also indicate that two conceptual elements---attention to social context and awareness of moral theory---are missing from the current conceptual framework in EE theory. These results suggest that the current framework should be expanded to emphasize the role of human and non-human communities: the development of a sense of place and the learning of environmentally responsible behavior must be situated within a social context. This study lends support to the view that for sense of place to move people to ethical action, it is crucial for them to recognize, and to participate in, a community of support and care.

    Full Text Available The paper presents the results of a study of cyanobacteria and green algae assemblages occurring in various tundra types determined on the basis of mosses and vascular plants and habitat conditions. The research was carried out during summer in the years 2009-2013 on the north sea-coast of Hornsund fjord (West Spitsbergen, Svalbard Archipelago. 58 sites were studied in various tundra types differing in composition of vascular plants, mosses and in trophy and humidity. 141 cyanobacteria and green algae were noted in the research area in total. Cyanobacteria and green algae flora is a significant element of many tundra types and sometimes even dominate there. Despite its importance, it has not been hitherto taken into account in the description and classification of tundra. The aim of the present study was to demonstrate the legitimacy of using phycoflora in supplementing the descriptions of hitherto described tundra and distinguishing new tundra types. Numeric hierarchical-accumulative classification (MVSP 3.1 software methods were used to analyze the cyanobacterial and algal assemblages and their co-relations with particular tundra types. The analysis determined dominant and distinctive species in the communities in concordance with ecologically diverse types of tundra. The results show the importance of these organisms in the composition of the vegetation of tundra types and their role in the ecosystems of this part of the Arctic.

    Aluminum alloys 5052, 3004, and Alclad 3003 and 3004 were exposed to flowing seawater at 2.44 m/s (8 fps) at the Seacoast Test Facility on Hawaii. One year data for warm surface water and three mouth data for cold water from 600 m depth are reported for free fouling, chlorinated and sponge ball cleaned conditions. All alloys pit in deep seawater, but show no pitting in warm surface water. Uniform corrosion in the warm water is initially rapid, but after 25 to 30 days the rate becomes slower and extrapolated 30 year material losses are in the 125 to 215 μm range. Chlorination at a level of 0.05 ppm for one hour per day has only a minor effect on corrosion rates, while sponge ball cleaning leads to erosion-corrosion of the Alclad surfaces and has no effect on alloy 5052. The need for additional testing in tropical seawater is discussed, as is the need for an improved understanding of the formation of inorganic scale films, their properties, and their effect on corrosion rates and heat transfer

    The Tatun volcanic group (TVG) and the Keelung submarine volcano (KSV) are active volcanoes and surrounding three nuclear plant sites in north Taiwan. The famous Jinshan-Wanli hot springs locates between TVG and KSV, moreover, the geochemical anomalies of acidic boiling springs on the seacoast infer that the origin is from magmatic fluids, sea water and meteoric water mixture, strongly implying that mantle fluids ascends into the shallow crust. The evidence for a magma chamber, submarine volcano, and boiling springs have a close spatial relationship. Based on UNECE specifications to Geothermal Energy Resources (2016), the Jinshan-Wanli geothermal area could be classified as Known Geothermal Energy Source for geothermal direct use and Potential Geothermal Energy Source for conventional geothermal system. High resolution reservoir exploration and modeling in Jinshan-Wanli geothermal area is developing for drilling risk mitigation. The geothermal team of National Taiwan Ocean University and local experts are cooperating for further exploration drilling and geothermal source evaluation.

  18. Effect of the foodchain in radioactivities released from thermal power plants

    1980-01-01

    Among many radionuclides released when burning fossil fuel 210 Pb and 210 Po are especially important, because they are very volatile, are released at higher rates than others, and are concentrated very strongly in marine organisms. This is particularly important in Japan, because most power plants in Japan are built near the seacoast and seawater contamination is likely. 210 Pb and 210 Po could also contaminate leafy vegetables by fallout. Since Japanese consume large amounts of seafoods and vegetables, this foodchain is important. The dose due to this foodchain is estimated. Although uncertainties are large and a definite conclusion cannot be drawn, the dose is one to three orders of magnitude higher when considering this foodchain than when not considering it. The average individual dose of Japanese due to this foodchain is of the order of several mrem/y. Although much smaller than the natural background, it is comparable to the dose of the total fuel cycle of full scale nuclear electricity generation, and so its social implication cannot be overlooked.

    A green roof is typically installed for one of two reasons: to mitigate the 'urban heat island' effect, reducing ambient temperatures and creating energy savings, or to reduce both the quantity and intensity of stormwater runoff, which is a major cause of river erosion and eutrophication. The study of green roofs in the United States has focused on commercial systems that use a proprietary expanded shale or clay substrate, along with succulent desert plants (mainly Sedum species). The green roof has the potential not only to provide thermal insulation and reduce storm runoff, but also to reclaim some of the natural habitat that has been lost to the built environment. Of special importance is the loss of habitat for pollinating insects, particularly native bees, which have been in decline for at least two decades. These pollinators are essential for crop production and for the reproduction of at least 65% of wild plants globally. Our study involves the installation of a small (4ft by 4ft), self-designed green roof system built with readily available components from a hardware store. The garden will be filled with a soilless potting mix, combined with 15% compost, and planted with grasses and wildflowers native to the Seacoast, New Hampshire region. Some of the plant species are used by bees for nesting materials, while others provide food in the form of nectar, pollen, and seeds for bees, butterflies, hummingbirds, and granivorous birds. We monitor precipitation on the roof and runoff from the garden on a per storm basis, and test grab samples of runoff for dissolved organic nitrogen and phosphorous. Runoff and nutrient concentration results are compared to a non-vegetated roof surface, and a proprietary Green Grid green roof system. This project is designed to address three main questions of interest: 1) Can these native plant species, which potentially provide greater ecosystem services than Sedum spp. in the form of food and habitat, survive in the conditions on

  20. Storminess-related rhythmic ridge patterns on the coasts of Estonia

    Full Text Available Buried or elevated coastal ridges may serve as archives of past variations in sea level and climate conditions. Sometimes such ridges or coastal scarps appear in patterns, particularly on uplifting coasts with adequate sediment supply. Along the seacoasts of Estonia, where relative-to-geoid postglacial uplift can vary between 1.7 and 3.4 mm/yr, at least 27 areas with rhythmic geomorphic patterns have been identified from LiDAR images and elevation data. Such patterns were mainly found on faster emerging and well-exposed, tideless coasts. These are mostly located at heights between 1 and 21 m above sea level, the formation of which corresponds to a period of up to 7500 years. Up to approximately 150 individual ridges were counted on some cross-shore sections. Ten of these ridge patterns that formed less than 4500 years ago were chosen for detailed characterization and analysis in search of possible forcing mechanisms. Among these more closely studied cases, the mean ridge spacing varied between 19 and 28 m. Using land uplift rates from the late Holocene period, the timespans of the corresponding cross sections were calculated. The average temporal periodicity of the ridges was between 23 and 39 years with a gross mean value of 31 years. Considering the regular nature of the ridges, they mostly do not reflect single extreme events, but rather a decadal-scale periodicity in storminess in the region of the Baltic Sea. Although a contribution from some kind of self-organization process is possible, the rhythmicity in ancient coastal ridge patterns is likely linked to quasi-periodic 25−40-year variability, which can be traced to Estonian long-term sea level records and wave hindcasts, as well as in regional storminess data and the North Atlantic Oscillation index.

  1. Establishment of nature reserves in administrative regions of mainland China.

    Full Text Available Nature reserves are widely considered as one available strategy for protecting biodiversity, which is threatened by habitat fragmentation, and wildlife extinction. The Chinese government has established a goal of protecting 15% of its land area by 2015. We quantitated the characteristics and distribution of nature reserves in mainland China and evaluated the expansion process for national nature reserves. National nature reserves occupy 64.15% of the total area of nature reserves. Steppe and meadow ecosystem, ocean and seacoast ecosystem, and wild plant nature reserves represent lower percentages, particularly in national nature reserves, in which they comprised 0.76%, 0.54%, and 0.69%, respectively, of the area. Furthermore, medium and small nature reserves compose 92.32% of all nature reserves. The land area under any legal protection has reached 14.80%, although only 9.78% is strictly protected. However, if 9 super-large national nature reserves, located in Southwest and Northwest China were removed, the percentage of strictly protected area decreases to 2.66% of the land area of China. The areas contained in nature reserves in each province are not proportional to the areas of the provinces, particularly for national nature reserves, with higher protection rates in Southwest and Northwest China than in other regions. Of the 31 provinces, 22 provinces feature strict protection of less than 4% of their areas by national nature reserves; these provinces are mainly located in East, Central, South, and North China. Moreover, the unevenness indexes of the distribution of nature reserves and national nature reserves are 0.39 and 0.58, respectively. The construction of nature reserves has entered a steady development stage after a period of rapid expansion in mainland China. In recent years, the total area of national nature reserves has increased slowly, while the total area of nature reserves has not increased, although the number of nature

  2. Economic Feasibility of Underwater Adduction of Rivers for Metropolises in Semiarid Coastal Environments: Case Studies

    2018-02-01

    Full Text Available The supply of raw water to the inhabitants of metropolises is not a trivial problem, and involves many challenges, both in terms of the quantity and quality of this water. When these metropolises are located in semiarid regions, this challenge takes on enormous proportions, and in many situations, there are no sustainable solutions, especially in times of global climate change. One hypothesis to try to mitigate this problem in coastal cities is the underwater adduction of rivers. The objective of this paper was to make the abstraction of drinking water in the mouths of great rivers near semi-arid regions. This water would be led by a pipeline below the water level and would follow the route of the seacoast, where the energy to move the water would be supplied by an axial hydraulic pump embedded in the pipeline by water-cooled electric motors driven by the energy generated from offshore wind turbines. Estimates have been made for the four metropolises in semi-arid regions: Fortaleza-Brazil, Dalian-China, Tel Aviv-Israel, and Gaza-Palestine, where it was possible to calculate economic viability through the Present Worth Value, the internal rate of return, and payback. The results indicated that Fortaleza had economic viability under restrictions. Dalian proved the ideal result. Tel Aviv and Gaza both had great economic viability, but only if Egypt agreed to supply water from the Nile. This paper proved that the management of the water supply for human consumption through the underwater adduction of rivers could be achieved with real clearance for any deficits in the volume of water that due to global climate change are becoming more frequent.

    Coastal communities with high population density and low topography are vulnerable from sea-level rise (SLR) caused by climate change. Groundwater in coastal communities will rise with sea level impacting water quality, the structural integrity of infrastructure, and natural ecosystem health. SLR-induced groundwater rise has been studied in areas of high aquifer transmissivity and in low-lying areas immediately along the coast. In this regional study, we investigate SLR-induced groundwater rise in a coastal area characterized by shallow unconsolidated deposits overlying fractured bedrock, typical of the glaciated northeast United States. MODFLOW, a numerical groundwater-flow model, is used with groundwater observations, lidar topography, surface-water hydrology, and groundwater withdrawals to investigate SLR-induced changes in groundwater levels and vadose-zone thickness in New Hampshire's Seacoast. The SLR groundwater signal is detected up to 5 km from the coast, more than 3 times farther inland than projected surface-water flooding associated with SLR. Relative groundwater rise ranges from 38 to 98% of SLR within 1 km of the shoreline and drops below 4% between 4 and 5 km from the coast. The largest magnitude of SLR-induced groundwater rise occurs in the marine and estuarine deposits and land areas with tidal water bodies on three sides. In contrast, groundwater rise is dampened near streams. Groundwater inundation caused by 2 m of SLR is projected to contribute 48% of the total land inundation area in the City of Portsmouth with consequences for built and natural resources. Freshwater wetlands are projected to expand 3% by year 2030 increasing to 25% by year 2100 coupled with water-depth increases. These results imply that underground infrastructure and natural resources in coastal communities will be impacted by rising groundwater much farther inland than previously thought when considering only surface-water flooding from SLR.

    The intertidal zone of seacoasts, being affected by the superimposed tidal, diurnal and lunar cycles, is temporally the most complex environment on earth. Many marine organisms exhibit lunar rhythms in reproductive behaviour and some show experimental evidence of endogenous control by a circalunar clock, the molecular and genetic basis of which is unexplored. We examined the genetic control of lunar and diurnal rhythmicity in the marine midge Clunio marinus (Chironomidae, Diptera), a species for which the correct timing of adult emergence is critical in natural populations. We crossed two strains of Clunio marinus that differ in the timing of the diurnal and lunar rhythms of emergence. The phenotype distribution of the segregating backcross progeny indicates polygenic control of the lunar emergence rhythm. Diurnal timing of emergence is also under genetic control, and is influenced by two unlinked genes with major effects. Furthermore, the lunar and diurnal timing of emergence is correlated in the backcross generation. We show that both the lunar emergence time and its correlation to the diurnal emergence time are adaptive for the species in its natural environment. The correlation implies that the unlinked genes affecting lunar timing and the two unlinked genes affecting diurnal timing could be the same, providing an unexpectedly close interaction of the two clocks. Alternatively, the genes could be genetically linked in a two-by-two fashion, suggesting that evolution has shaped the genetic architecture to stabilize adaptive combinations of lunar and diurnal emergence times by tightening linkage. Our results, the first on genetic control of lunar rhythms, offer a new perspective to explore their molecular clockwork.

    In Brazil the most important concentrations of monazite sands occur in the beaches and sandbanks that extend throughout the coast, from the State of Rio Grande do Norte down to the State of Rio Grande do Sul, Brazil. Nowadays, the most important Brazilian monazite concentrations - considered as being the fourth worldwide reservoir of rare-earth elements - are located at the north seacoast of the State of Rio de Janeiro, near Buena town. At this location the Brazilian Nuclear Industries - INB - manages an industrial complex for prospecting, mining and physical separation and concentration of monazite sands. Among the elements present at the monazite sands there are the radioelements thorium and uranium, which make the monazite sand a radioactive mineral. Monazite is constituted basically of 62% in TR{sub 2}0{sub 3} (rare-earth oxides), 5,5% of thorium in Th0{sub 2} (thorium oxide) and 0,25% of uranium in U{sub 3}0{sub 8} (uranium oxide). The general objective of the present work was to estimate the occupational doses at the industrial complex for prospecting, mining and physical separation and concentration of monazite sands located at Buena, at the north of the State of Rio de Janeiro. The occupational exposures occur mainly through the inhalation of airbone dust particles of mineraIs containing thorium and uranium, during the prospection and physical separation and concentration of monazite. To evaluate the impact of the occupational exposures during the physical separation and concentration of monazite, it was necessary to evaluate the effective equivalent doses due to thorium contamination of the air and the exposures due to the daughter radionuclides from the natural series of uranium and thorium. The results obtained at the present work showed that, although occupational doses are within the annual dose limits established by the Brazilian regulatory authority - CNEN - in some of the working places within the industrial complex the concentrations of

    A study of village women in Haiti which presents baseline data from their responses to stylized health education pictures is reported. The study questioned the concept that pictorial messages were accurately recognized and self-explanatory to nonliterate Haitian village women. The investigator, who used a descriptive survey, sought answers to a major and a related question: what do nonliterate Haitian village women recognize in selected health education pictures; and are their differences in picture recognition traceable to the complexity of the pictures. There were 110 women (25 from a mountain village, 25 from a plains village, 25 from a seacoast village, and 35 urban dwellers) who responded to 9 health education pictures. The women ranged in age from 18-80 years of age; 32 (29%) had gone to school for a range of an "unknown time" to 8 years. 47% of those who had gone to school indicated that they could read. The investigator rated the verbatim responses to the pictures for accuracy as: accurate, overinclusive, underinclusive, inaccurate, and do not know. The quantitative analysis of this data revealed that the accuracy levels decreased as the complexity level increased. This is best shown in the 129 (39%) accurate responses in the low level; 6 (1.8%) in the moderate level; and no accurate responses in the high complexity level. An unexpected finding was the highest number of inaccurate responses (n = 83, 25.1%) found in the low complexity level, while the moderate and high levels both showed 36 (10.8%). In addition to the differences in accuracy in picture recognition based on picture complexity, there were significant differences on the chi-square test which confirmed the assertion of the question that picture recognition is traceable to the complexity of the picture. These findings are consistent with the picture complexity studies of Holmes, Jelliffe, and Kwansa.

    Full Text Available Formation of bioaerosol is an important process of mass and energy exchange between sea and atmosphere by means of droplets of marine dust. Studies on aerosol activity of the sea was developed in the last decades of the 20 th century. Those studies revealed that concentrations of bacteria in aerosol droplets were hundreds times higher than their concentrations in superficial parts of seawater. The research also proved that aerosol activity of the sea can influence the sanitary condition of the air, especially at the seacoast areas. Surveys of air structure in coastal regions were performed on the Tricity beaches as well as in Sobieszewo and Komary. Atmospheric air sampling stations in the marine zone were located on the Gulf of Gdansk at the Vistula river mouth. Air samples were collected from the front platform on the ship R/V Baltica at 4m above the sea surface. The air samples were collected by filtration method using Sartorius apparatus. Airborne microbes were deposited onto sterile gelatine Sartorius filters. All filters were exposed directly towards the oncoming wind. After sampling, the exposed filters were placed onto the agar media on Petri plates and incubated. All measurement results were depicted in (CFU/m3 i.e. colony forming units in 1 m3 of the examined air. Meteorological measurements included: temperature, humidity, wind speed and direction. The obtained results revealed that statistically significant trends were observed between the total number of bacteria or moulds and a season of sampling. The greatest number of microorganisms was noted in spring and autumn. Correlation analysis showed that statistically significant relationship exists between microbial abundance and the wind direction or speed and location of sampling site. Large quantities of fungal spores was detected in the areas of Gdynia and Gdansk - Brzeêno when south-west winds were blowing from the land. The highest number of bacteria were observed at the sampling

    The knowledge of the ground-beetle fauna of Strandzha is currently incomplete, and is largely based on data from the Bulgarian part of the region and on records resulting from casual collecting. This study represents a critical revision of the available literature, museum collections and a three years field study of the carabid beetles of the Bulgarian and Turkish parts of Strandzha Mountain and the adjacent Black Sea Coast territories. A total of 328 species and subspecies of Carabidae, belonging to 327 species from the region of Strandzha Mountain and adjacent seacoast area, have been listed. Of these, 77 taxa represent new records for the Bulgarian part of the region, and 110 taxa new records for Turkish part of the studied region. Two taxa, one subgenus (Haptotapinus Reitter, 1886) and one species (Pterostichus crassiusculus), are new to the fauna of Bulgaria. Based on a misidentification, the species Apotomus testaceus is excluded from the list of the Bulgarian fauna. Seven species (Carabus violaceus azurescens, Apotomus rufus, Platynus proximus, Molops alpestris kalofericus, M. dilatatus angulicollis, Pterostichus merklii, and Calathus metallicus) are treated as doubtful for the regional fauna, and one (Apotomus rufus) also for the Bulgarian fauna. Altogether, 43 taxa collected in the Turkish part of the region are new for European Turkey. New taxa for Turkey are the genera Myas and Oxypselaphus, the subgenus Feronidius, and nine species and subspecies (Carabus granulatus granulatus, Dyschirius tristis, Bembidion normannum apfelbecki, B. subcostatum vau, Acupalpus exiguus, Myas chalybaeus, Oxypselaphus obscurus, Pterostichus leonisi, Pt. melas). In addition, there are a further seven species that are here confirmed for Turkey.

    Seacoast Science develops chemical sensors that use polymer-coated micromachined capacitors to measure the dielectric permittivity of an array of selectively absorbing materials. We present recent results demonstrating the sensor technology's capability to detect components in explosives and toxic industrial chemicals. These target chemicals are detected with functionalized polymers or network materials, chosen for their ability to adsorb chemicals. When exposed to vapors or gases, the permittivity of these sorbent materials changes depending on the strength of the vapor-sorbent interaction. Sensor arrays made of ten microcapacitors on a single chip have been previously shown to detect vapors of organic compounds (chemical warfare agents, industrial solvents, fuels) and inorganic gases (SO2, CO2, NO2). Two silicon microcapacitor structures were used, one with parallel electrode plates and the other with interdigitated "finger-like" electrodes. The parallel-plates were approximately 300 μm wide and separated by 750 nm. The interdigitated electrodes were approximately 400 μm long and were elevated above the substrate to provide faster vapor access. Eight to sixteen of these capacitors are fabricated on chips that are 5 x 2 mm and are packaged in less than 50 cm3 with supporting electronics and batteries, all weighing less than 500 grams. The capacitors can be individually coated with different materials creating a small electronic nose that produces different selectivity patterns in response to different chemicals. The resulting system's compact size, low-power consumption and low manufacturing costs make the technology ideal for integration into various systems for numerous applications.

    Full Text Available Guanabara bay is an estuary environment situated in the seaboard of Rio de Janeiro state, under the coordinates 22º 40’ and 23º 00’S and 43º 00’ and 43º 20’W. Nowadays, it has an approximate area of 377 km2, it has had a reduction of 91 km2 since the discovery of Brazil, being considered one of the most polluted seacoast regions of the country. The environmental monitoring of Guanabara bay becomes increasingly necessary in order to be capable of taking effectivemeasures in its management. Therefore, the use of bioindicator organisms, like foraminifera, is an excellent tool because of their rapid response to environmental changes. The goal of this paper is to apply statistical analyses to the biotic data benthicforaminifera, aiming to observe how they behave in Guanabara bay. In November 1999, samples of bottom sediment were collected along Guanabara bay; 52 of them distributed along all the bay were used in this study. They were treated and classified according to the pattern methodology for foraminifera. For the numerical ecology, grouping analysis and indicating species analysis (ISA were done using the programs Statistica 6.0 and PCORD. Through the groupinganalysis, it was observed the formation of groups in both samples and species. ISA showed what species is the best one toindicate the actual state of Guanabara bay - Ammonia tepida. The multivaried ecological analyses had an optimal response in the evaluation of patterns of pollution in Guanabara bay, based on benthic foraminifera.

  11. Empire, War and Nation: Heritage Management Perspectives from Canada and Malta

    Directory of Open Access Journals (Sweden)

    2006-06-01

    Full Text Available This article offers recent insights on contested heritage from Canada and Malta. These contrasting geographical extremes span a range of heritage dissonances but share a common historical identity as successor states to the British Empire, entailing familiar postcolonial heritage equivocations. Dissonances between colonial and indigenous heritage meanings are discussed. The principal focus of the paper is the Empire at war, as an issue of heritage management in Ottawa, the capital of Canada, and in Malta; comparative insights are generated with resonance for other imperial successor states such as Australia, New Zealand and Singapore. In Ottawa the National Capital Commission is engaged in a delicate management of heritage evolution from the imperial past to the multicultural present, involving adjustment and diversification of heritage meanings in which the indigenous peoples and Canada's wartime/military history figure prominently. Malta's time-depth generates an embarrassment of heritage resources, necessitating choices as it moves from 'blue' seacoast to 'grey' heritage tourism; while earlier eras are favoured, the British imperial and military heritage is inescapable, especially the heroic shared defence of 1940-3, generating management issues over recency, postcoloniality, the naval legacy and the problem of marketing to the former enemy populations. Questions of whose heritage, using which resources of what period, for whose benefit and how managed, elicit a different range of answers in the two cases: British colonial heritage is too diverse to be value-generalised, and there is no single, immutable colonial template for postcolonial identity. However, the particular legacy of the Empire at war is notably formative in the evolution of succeeding national identities.

    Full Text Available The paper is devoted to psychological aspects and psychological perception of spatial and temporal dimensions of the historical process. Space and time do not exist separately, they are closely interconnected: everything that happens in history has certain spatial and temporal position. From historical perspective spatial characteristics of a particular territory are twofold: territory’s psychical position remains unperturbed, while its political status and national affiliation are revised in the course of time. Territories vary in their value: the most valuable objects of physical environment such as sea-coasts, courses and estuaries of rivers, mineral deposits, industrial regions, etc. serve as objects of contention on the international arena, while areas that do not possess such characteristics can be of no interest to international actors. Historical time does not necessarily coincide with chronological time. For example, according to Eric Hobsbawm, the so-called long Nineteenth Century lasted from 1789 to 1914, while the short Twentieth Century lasted only from 1914 to 1991. Psychological time should also be taken into account – perception of relation between past, present, and future developments, as well as perception of chronological intervals within which certain historical developments take place. Time sets chronological framework for the historical process, it can be both cyclical and linear at the same time. Progress in transportation and communication leads to the situation where linear characteristics of space and time remain the same, while space compresses and time accelerates: movement of physical objects and information transfer take less and less time. Such process was ushered in during the Nineteenth Century (Transportation and Communication Revolutions and it accelerated in the Twentieth and Twenty-First Centuries. Present wars can last only months and days, not years; negotiations are conducted directly by chief

    In Brazil the most important concentrations of monazite sands occur in the beaches and sandbanks that extend throughout the coast, from the State of Rio Grande do Norte down to the State of Rio Grande do Sul, Brazil. Nowadays, the most important Brazilian monazite concentrations - considered as being the fourth worldwide reservoir of rare-earth elements - are located at the north seacoast of the State of Rio de Janeiro, near Buena town. At this location the Brazilian Nuclear Industries - INB - manages an industrial complex for prospecting, mining and physical separation and concentration of monazite sands. Among the elements present at the monazite sands there are the radioelements thorium and uranium, which make the monazite sand a radioactive mineral. Monazite is constituted basically of 62% in TR 2 0 3 (rare-earth oxides), 5,5% of thorium in Th0 2 (thorium oxide) and 0,25% of uranium in U 3 0 8 (uranium oxide). The general objective of the present work was to estimate the occupational doses at the industrial complex for prospecting, mining and physical separation and concentration of monazite sands located at Buena, at the north of the State of Rio de Janeiro. The occupational exposures occur mainly through the inhalation of airbone dust particles of mineraIs containing thorium and uranium, during the prospection and physical separation and concentration of monazite. To evaluate the impact of the occupational exposures during the physical separation and concentration of monazite, it was necessary to evaluate the effective equivalent doses due to thorium contamination of the air and the exposures due to the daughter radionuclides from the natural series of uranium and thorium. The results obtained at the present work showed that, although occupational doses are within the annual dose limits established by the Brazilian regulatory authority - CNEN - in some of the working places within the industrial complex the concentrations of radionuclides in air are above the

    Full Text Available Swimming is unnatural activity for human beings. Unlike most of all other animals, we are not born with an instinct for swimming. However, ancient peoples who settled a long seacoasts, lakeshores, and riverfronts had to learn to swim for gathering food and for simple survival. From this necessity, recreational swimming would have developed, both as an activity for individuals and as a group social practice. In many ancien t civilizations, communal swimming and, later, bathing rituals were an integral part of society. By the nineteenth century, a growing middle class in Europe and America began to enjoy vacation time at beaches and resorts with the convenience and efficiency of the expanding network of railroads. “Taking the waters” at a seashore meant wading out into the shallows buoyed by a floating canopy to prevent sunburn and to shield against prying eyes. Not until the mid - 1800s did special forms of attire develop for p ublic bathing. Even then, bathing costumes still closely resembled street clothing. But, such outfits were terrible weight burdens in wet, and drownings were common for the unwary. So, as more and more people began to request bathing costumes from their dressmakers, fashion styling diverged from daytime modes. Clothing for swimming, bathing, and seaside wear has been an important and influential area of fashionable dress since the late nineteenth century. The evolution of swimming and bathing costumes has been closely associated with trends in mainstream fashion and advancements in textile technology, but has also reflected broader societal attitudes about personal hygiene, body exposure, and modesty, and wheth er or not it was appropriate for women to participate in active sports. In this study, aimed to examine changes in model and material of swimsuits from the introduction to the end of twenties .

    Urban and peri-urban forests are recognized as basic elements for Nature-Based Solutions (NBS), as they preserve and may increase environmental quality in urbanized contexts. For this reason, the amount of forest land per inhabitant is a pivotal efficiency indicator to be considered in the sustainable governance, land management, planning and design of metropolitan areas. The present study illustrates a multivariate analysis of per-capita forest area (PFA) in mainland Attica, the urban region surrounding Athens, Greece. Attica is considered a typical case of Mediterranean urbanization where planning has not regulated urban expansion and successive waves of spontaneous growth have occurred over time. In such a context, an analysis of factors that can affect landscape changes in terms of PFA may inform effective strategies for the sustainable management of socio-ecological local systems in light of the NBS perspective. A total of 26 indicators were collected per decade at the municipal scale in the study area with the aim to identify the factors most closely associated to the amount of PFA. Indicators of urban morphology and functions have been considered together with environmental and topographical variables. In Attica, PFA showed a progressive decrease between 1960 and 2010. In particular, PFA progressively declined (1980, 1990) along fringe areas surrounding Athens and in peri-urban districts experiencing dispersed expansion of residential settlements. Distance from core cities and from the seacoast, typical urban functions (e.g., multiple use of buildings and per capita built-up area) and percentage of agricultural land-use in each municipality are the variables most associated with high PFA. In recent years, some municipalities have shown an expansion of forest cover, mainly due to land abandonment and forest recolonization. Findings from this case study have allowed us to identify priorities for NBS at metropolitan level aimed at promoting more sustainable

    Full Text Available At the dawn of this third millennium, growing numbers of forums worldwide are focused on the issue of how to sustain the diversity of the nature and of cultures for the well-being of the Earth and humanity. Concurrently, intercultural and interreligious dialogue is deemed essential for social cohesion. This dissertation advances the contributions of religiosity in art through a qualitative reflective account and chronicle of the art and dialogues offered by people of diverse cultures and faiths from 1999 to 2004 during Sharing Art & Religiosity in the vicinity of Pura Samuan Tiga in Bedulu, Bali and Sharing Art Ocean– Mountain at  the  seacoast village of Tejakula, North  Bali;  seen in  tandem  with creative transformations that occurred through Sharing Art in and with other cultural environments of the world. Methodologically this study stemmed from and demonstrates the merits of public participatory   practice-based   art   programs   whereby   activities   are   conceived   by   and implemented with the people of a locale. Participants generated the data and interpretations via mutual cooperation, dialogue, and creative praxis. The Balinese principle of Tri Hita Karana, that aims toward a harmonious human-nature-God/Source of Life relationship in accord with the place-time-conditions, provided a holistic perspective to analyze and derive meaning from the results. Findings indicate sharing in the arts, religiosity, and nature fosters a common field such that traditional and modern cultures can study and engage in creative dialogue together. Moreover, interreligious innovations that have continued to develop since the seminal deliberation  of  reconciliation  between  Bali  Aga,  Çiwaist,  and  Buddhist  faith  groups  at Samuan Tiga circa CE 989 to 1011 and intercultural egalitarian innovations since the seventeenth century dialogue of indigenous and migrant mountain and maritime cultures in Tejakula

    This study deals with the characteristics of throughfall produced by vine (Vitis vinifera L.) in one of the most common pedoclimatic conditions for grape production: a soil derived from marine sediments under a temperate Mediterranean climate, and located rather close to the seacoast. To distinguish the contribution of the plant from that of the atmospheric deposition, the throughfall was collected for more than one year under real and artificial (plastic) vines; for the same period, also the bulk precipitation was collected. The solution collected were analysed for pH, electrical conductivity, and concentration of cations and anions. For each event, the ionic fluxes of bulk precipitation and throughfall were calculated. Results indicated that the chemical composition of the bulk precipitation was strongly influenced by the proximity of the seashore and, to a lesser extent, by local anthropic activities and windblown material coming from distant areas. The chemical composition of the throughfall was affected by the same factors of bulk precipitation, but also by solubilisation of dry deposition trapped by the canopies, agronomic practices, plant, and living-on-the-leaves microorganisms. The comparison of the characteristics of the throughfall of the real with the artificial vines revealed that the vines are a source of Mg and K. During winter season, the reduction of Ca, NH{sub 4} and PO{sub 4} from bulk precipitation to throughfall was ascribed to the formation of biogenic minerals on the plant surface. The presence of these minerals was proved by X-ray diffraction on the powders collected during the winter season on the surface of cordons and fruiting canes. We conclude that an approach to the estimation of the nutritional potentiality of the soil that includes the contribution of the throughfall is functional to the management of the agro-ecosystem. -- Highlights: Black-Right-Pointing-Pointer The characteristics of the throughfall of vines are affected by

    This paper presents a new thermal stress index for dairy cows in inter-tropical regions, with special mention to the semi-arid ones. Holstein cows were measured for rectal temperature ( T R), respiratory rate ( F R) and rates of heat exchange by convection ( C), radiation ( R), skin surface evaporation ( E S) and respiratory evaporation ( E R) in the north eastern region of Brazil, after exposure to sun for several hours. Average environmental measurements during the observations were air temperature ( T A) 32.4 °C (24.4-38.9°), wind speed ( U) 1.8 m.s-1 (0.01-11.0), relative humidity 63.6 % (36.8-81.5) and short-wave solar radiation 701.3 W m-2 (116-1,295). The effective radiant heat load (ERHL) was 838.5 ± 4.9 W m-2. Values for the atmospheric transmittance ( τ) were also determined for tropical regions, in order to permit adequate estimates of the solar radiation. The average value was τ = 0.611 ± 0.004 for clear days with some small moving clouds, with a range of 0.32 to 0.91 in the day period from 1000 to 1300 hours. Observed τ values were higher (0.62-0.66) for locations near the seacoast and in those regions well-provided with green fields. Effects of month, location and time of the day were all statistically significant ( P cows exposed for 1 to 8 h to sun during the day; in 7 months (February, March, April, July, August, September and November), 4 days per month on the average. A principal component analysis summarised the T R, F R, C, R, E S and E R measurements into just one synthetic variable ( y 1); several indexes were then obtained by multiple regression of y 1 on the four environmental variables and its combinations, by using Origin 8.1 software (OriginLab Corp.). The chosen equation was the index of thermal stress for cows, ITSC = 77.1747 + 4.8327 T A - 34.8189 U + 1.111 U 2 + 118.6981 P V - 14.7956 P V 2 - 0.1059 ERHL with r 2 = 0.812.

    The great number of Greek silver coins from the first century BC found in the Balkan - Carpathian region have aroused a sharp interest among numismatic researchers. The problem is to classify these coins - tetradrachmae of Thasos and drachmae of Apollonia and Dyrrachium into originals, copies and imitations, in relation to their provenance. Well known are Celtic Thasos tetradrachmae copies (good quality coins), and also Barbarian imitations (absence or misspelling of the legend, disproportionate and simplified figures). Thracians, Dacians and Celts used to produce the same type of coins. The dies used for coining were bought or stolen from the Greeks, while some local engravers manufactured their own dies. Visual examination, the first step of a numismatist's work, is insufficient to classify the coins. This is the reason why elemental analysis is required (X-Ray Fluorescence and Proton Induced X-ray Emission methods). 36 Thasos tetradrachmae and 145 Apollonia and Dyrrachium drachmae, struck between 60 and 48 BC, a very intense period of civil Roman wars, belonging to Tarii Crisurilor Museum in Oradea and to Budapest National Museum were analyzed. The fingerprint of the third group of Thasian tetradrachmae is the bromine. The presence of this element in silver coins is mentioned in the literature, where bromine is linked to marine spray (the hoard was found near the seacoast). In our case, the coins were found in a region far away from the Black Sea coast. Taking into account the presence of bromine in silver ore from the Transylvania mine Rodna and supposing an imperfect procedure of refinement , these coins could be attributed to local workshops. As for the Apollonia and Dyrrachium drachmae, a similar situation can be retraced. Because of the high silver content and refined aspect of the coins belonging to the first group, one can assume that these drachmae are the original ones, minted of Macedonian silver. The percentage of copper in the second group of coins

    Full Text Available This article is a debate on research that deals with categories pre-defined in the public agenda. It is supported by an experience of doing an anthropological study for the Tupinambá of Olivença aimed at the identification of a juridical category of “indigenous land” defined by the 1988 Constitution of Brazil. The main argument developed in this article starts with the assumption that in the contemporary situation the definition of public categories that involves cultural and social rights of minorities, such as terra indígena, have been defined in public debates in which anthropologists were involved. One of the necessary results of such a situation is that anthropology cannot see these categories as exogenous concepts to be criticized, but as categories of knowledge to be addressed. A detailed proposition of how I have addressed the issue concerning the delimitation of the seacoast border of the indigenous land of the Tupinambá of Olivença is here developed, showing how ethnography in anthropology is a particularly good device to achieve this challenges. Through the Tupinambá case, it is showed how ethnography as situated knowledge, enmeshed in a comparative project and prepared to incorporate the struggles that people face when dealing with conflict situations, intertwines public and indigenous definitions of social categories (in this case, the land through what is here named compatible agendas.Neste artigo proponho uma forma de a antropologia lidar com investigação sobre categorias de conhecimento que foram definidas previamente na agenda pública.

In the beginning of the painting works, while painting the dome space, the renowned founders found a very good painter, but he, for some reason ended his work never finishing the job. Around 1370 the founders did not have an opportunity to find a good painter, so they hired a group of painters from the Seacoast that had no qualities. Their drawings were much more simplified and painting procedure quite poor. The flat portraits and bodies without volume with thin arms are weightless. And in combination with poor colouring they clearly stand aside compared to the total medieval Serbian painting. By style, but spatially very far away, the similarities can only be found in the paintings of Georgia. On the other hand, the total ideological and theological creation of the painting program is on a very high level and undoubtedly expresses the spirituality of the founder and the local episcope. The symbolical connection had been set and between cycles where all the saints of the church year were presented together with the composition of the The Doom. The organic connection has been established with the whole content of Christian dogma and the earthly history of the founder and his family. The program narration has strong messages on multiple family and legal belonging to the ruling house of Nemanjić. The Doom is in symbolical function with the ruler's iconography and setting of the divine rights of the earthly rule of the founders their parents as suzerains and their descendants.

The aim of this work was to identify, by means of ageoelectric survey, the cores of the original islands. Normally, structures near the sea-coast cannot be detected through geoelectric measurements. This is due to the presenceof salt water in sediments.

    One of the greatest earthquakes of all time struck south-central Alaska on March 27, 1964. Strong motion lasted longer than for most recorded earthquakes, and more land surface was dislocated, vertically and horizontally, than by any known previous temblor. Never before were so many effects on earth processes and on the works of man available for study by scientists and engineers over so great an area. The seismic vibrations, which directly or indirectly caused most of the damage, were but surface manifestations of a great geologic event-the dislocation of a huge segment of the crust along a deeply buried fault whose nature and even exact location are still subjects for speculation. Not only was the land surface tilted by the great tectonic event beneath it, with resultant seismic sea waves that traversed the entire Pacific, but an enormous mass of land and sea floor moved several tens of feet horizontally toward the Gulf of Alaska. Downslope mass movements of rock, earth, and snow were initiated. Subaqueous slides along lake shores and seacoasts, near-horizontal movements of mobilized soil (“landspreading”), and giant translatory slides in sensitive clay did the most damage and provided the most new knowledge as to the origin, mechanics, and possible means of control or avoidance of such movements. The slopes of most of the deltas that slid in 1964, and that produced destructive local waves, are still as steep or steeper than they were before the earthquake and hence would be unstable or metastable in the event of another great earthquake. Rockslide avalanches provided new evidence that such masses may travel on cushions of compressed air, but a widely held theory that glaciers surge after an earthquake has not been substantiated. Innumerable ground fissures, many of them marked by copious emissions of water, caused much damage in towns and along transportation routes. Vibration also consolidated loose granular materials. In some coastal areas, local

  8. Relation of streams, lakes, and wetlands to groundwater flow systems

    Winter, Thomas C.

    Surface-water bodies are integral parts of groundwater flow systems. Groundwater interacts with surface water in nearly all landscapes, ranging from small streams, lakes, and wetlands in headwater areas to major river valleys and seacoasts. Although it generally is assumed that topographically high areas are groundwater recharge areas and topographically low areas are groundwater discharge areas, this is true primarily for regional flow systems. The superposition of local flow systems associated with surface-water bodies on this regional framework results in complex interactions between groundwater and surface water in all landscapes, regardless of regional topographic position. Hydrologic processes associated with the surface-water bodies themselves, such as seasonally high surface-water levels and evaporation and transpiration of groundwater from around the perimeter of surface-water bodies, are a major cause of the complex and seasonally dynamic groundwater flow fields associated with surface water. These processes have been documented at research sites in glacial, dune, coastal, mantled karst, and riverine terrains. Résumé Les eaux de surface sont parties intégrantes des systèmes aquifères. Les eaux souterraines interagissent avec les eaux de surface dans presque tous les types d'environnements, depuis les petits ruisseaux, les lacs et les zones humides jusqu'aux bassins versants des vallées des grands fleuves et aux lignes de côte. Il est en général admis que les zones topographiquement hautes sont des lieux de recharge des aquifères et les zones basses des lieux de décharge, ce qui est le cas des grands systèmes aquifères régionaux.

    Full Text Available Since the beginning of the seventies the natural transmission of Chagas’ infection has been considered to be under control in the State of São Paulo and not even a case of American Trypanosomiasis, transmitted by triatomine bugs, has been detected by the epidemiological surveillance system. This situation justifies the report of a case of acute Chagas’ disease that occurred in a forest area considered free of domiciliary triatomines along the Southern seacoast of São Paulo State. In May, 1995 the presence of trypomastigote forms of Trypanosoma cruzi had been diagnosed in a retired 57 year-old male patient, born and living in Santos (São Paulo State, complaining of fever, fatigue and malaise. The patient reported that 40 days before he had participated with 17 friends in a 7-day excursion in a forest area of the municipalities of Itanhaém and Peruíbe. During this period the group had been lodged in three houses located within the forest. Eight days after the end of the excursion the patient began to have fever, malaise and fatigue. During the next 31 days he had received medical care both as an inpatient and an outpatient, without any significant improvement. After the detection of T. cruzi trypomastigotes in his blood stream the patient began to be treated with benzonidazole in a hospital but died 8 days after the beginning of treatment. The epidemiological investigation carried out showed no signs of the presence of triatomine bugs in the three houses where the group had been lodged, or any indication of Chagas' infection in other excursionistsDoença de Chagas aguda no Estado de São Paulo: aspectos epidemiológicos Desde o início da década de 70 a transmissão natural da infecção chagásica é considerada sob controle e as ações de vigilância epidemiológica desde então desenvolvidas não têm detectado ocorrência de novos casos de tripanosomíase americana, transmitidos por triatomíneos, no Estado de São Paulo.

    études, associations… conduisent de plus en plus d’opérations dans le cadre de territoires de projets calqués sur des espaces de pratiques. Ces derniers restent néanmoins largement assujettis aux découpages administratifs traditionnels au point de voir leurs dimensions régulièrement redéfinies.In the era of mass tourism and leisure, pleasure sailing is a particular expression of territoriality through various equipment on the coast (ports, marinas, shipyards, etc. and of maritime as terrestrial flows (routes followed at sea by the yachtsmen between ports, connections between residence and loading points, shuttles between residence and work for professionals of pleasure, sailing, etc. This “amphibious” character confers on the pleasure sailing an atypical place among the tourist activities.In France, more than for other leisures, the pleasure sailing is quartered between reference spaces, (resulting essentially from the trajectories of the yachtsmen, navigation basins, cruising basins, pleasure sailing basins…, and of administrative territories concerned with a quite different logic on the ground (territorial collectivities, subdivisions of the maritime businesses and at sea (territorial water, zone of exercise of police rights.Like many other “lived” spaces, the surfaces for practice of pleasure sailing are particularly complex. In addition to their chronic character, taking into account the primarily seasonal character of the activity, these territories will depend on the diversity of the practices (fishing, strolls at sea, coastal cruising, deep-sea cruising, sporting sailing, of the unconscious or conscious limits that each yachtsman fixes, of the physical determinism (obstacles to navigation, winds, currents…, of the current regulations which prohibits navigation beyond certain distance from a shelter according to the various categories of ships, etc. As for the management territories, they stem from a mainly continental logic, even on the seacoast.
