    [Purpose] The aim of this study was to investigate the influence of gender and family factors on performance in the fine motor domain of the Denver II developmental screening test. [Subjects and Methods] Data were obtained from 2038 healthy children, 999 boys (49%) and 1039 girls (51%) in four age groups: 0-24 months (57%), 25-40 months (21.1%), 41-56 months (10.4%), and 57-82 months (11.5%). [Results] Female gender, higher maternal age, especially in children older than 24 months, and higher maternal education were associated with earlier accomplishment of fine motor items. Higher socioeconomic status was correlated with fine motor skills more noticeably at young ages. [Conclusion] The results of this study support the role of environmental factors in the interpretation of fine motor test results and point to target groups for intervention, such as infants in the low socioeconomic group and preschool children of less educated mothers. Studies in different populations may reveal particular patterns that affect child development.

    Full Text Available The territorial system overlapping cross-border areas shapes a particularly dynamic and complex functional area. This paper synthesises several research outcomes regarding the social and environmental dysfunctions and opportunities defining the marginal territories that were emphasised during the ‘Analysis and diagnosis of the current situation in the cross-border area’, a phase of the project ‘Common Strategy of Sustainable Territorial Development of the Romanian-Bulgarian Cross-Border Area’ (SPATIAL. The main indicators concerning the population structure and movement highlight a series of problematic aspects within the cross-border area: population decline, significant rural population concentration on the Romanian side, demographic ageing, increase in the age dependency ratio, and a negative natural growth and migration rate. The analysis also indicates areas of socio-demographic potential that are marked by population growth, a significant young population presence that is convergent with an important share of active population. In this perspective, the spatial analysis also focused on identifying natural drivers affecting development and restrictive factors, on the environmental quality evaluation, as well as on establishing areas exposed to natural and technological risks. Therefore, delineating and analysing components underlying social and environmental processes were intended to determine those issues and opportunities considered to influence the evolution of this potentially functional area.

    The Euro-Arctic region is currently experiencing rapid changes in environmental, social and economic conditions. The issue of environmental radioactivity is of special concern to the Arctic region due to numerous existing and potential sources of radioactive pollution in the immediate and adjacent areas. Due to cross-border nature of any potential radioactive contamination and common challenges in border countries, one should consider risks related to radioactivity, monitoring and protection at a regional and international level. This research presents results of cross-border cooperation between Norway, Finland and Russia and joint assessment of the status of terrestrial radioactivity in the Euro-Arctic region and in particular across Troms and Finnmark (Norway), Lapland (Finland) and Murmansk Oblast (Russia). To assess current environmental radioactivity levels in the terrestrial environment, environmental samples were collected in each country in 2010-2012. The main focus was comparison of radioactivity levels in the natural food products such as berries, mushrooms and freshwater fish. The results showed that large variations in activity concentrations exist between species and sampling areas. However, activity concentrations of {sup 137}Cs in all berries and mushrooms in Northern Norway, Finland and Russia were below the national limits set for commercial retail and well below the national limits for freshwater fish from Northern Norway and Finland. The sampled species from three countries were analysed in order to find out reference species available for further monitoring and data comparison. The doses to man arising from consumption of berries, mushrooms and freshwater fish were calculated. To compare overall terrestrial radioactivity levels in the Euro-Arctic region, partners exchanged long-term monitoring data available in the three countries such as data for soil, vegetation, berries, mushrooms, lichens, reindeer meat, freshwater fish, whole body counting

  7. Toward a methodology for evaluating website of government environmental agencies in the northern border

    2014-01-01

    Full Text Available In the environmental field of the northern Mexican border make use of websites toprovide information and services to society in order to achieve a better interaction about the environmental work. In spite of that, and since there are various schemes and government programs that set objectives to be met by this online offer, little is known about the extent of achievement of these objectives. Therefore, this study tries to find out if these sites are fulfilling the objectives that motivate their creation and their setting online. From this initial assessment, it is confirmed that local government’s websites are likely to have a lower compliance of objectives. It was observed that the objective that is more often fulfilled on the three levels of government was offering visible and structured services, in a lesser extent to implement citizen participation.

    Full Text Available This article highlights the role played by the ONG’S in front of the environmental damage in the border region, which we share with the United States. Its objective is to show the scope and the achievements, as well as the challenges and the goals of these new social actors. If we agree about the environment damage is one of the global issues, presented as an critical concern both for the Northern countries as for the Southern countries. The Mexico-United States borderline is an excellent test laboratory to verify not only the existence and action of new groups and social individuals, but also to bring to a discussion table the damage, chaos and environment dangers of this region shared with the United States.

  10. Spatial Downscaling of TRMM Precipitation Using Geostatistics and Fine Scale Environmental Variables

    Directory of Open Access Journals (Sweden)

    No-Wook Park

    2013-01-01

    Full Text Available A geostatistical downscaling scheme is presented and can generate fine scale precipitation information from coarse scale Tropical Rainfall Measuring Mission (TRMM data by incorporating auxiliary fine scale environmental variables. Within the geostatistical framework, the TRMM precipitation data are first decomposed into trend and residual components. Quantitative relationships between coarse scale TRMM data and environmental variables are then estimated via regression analysis and used to derive trend components at a fine scale. Next, the residual components, which are the differences between the trend components and the original TRMM data, are then downscaled at a target fine scale via area-to-point kriging. The trend and residual components are finally added to generate fine scale precipitation estimates. Stochastic simulation is also applied to the residual components in order to generate multiple alternative realizations and to compute uncertainty measures. From an experiment using a digital elevation model (DEM and normalized difference vegetation index (NDVI, the geostatistical downscaling scheme generated the downscaling results that reflected detailed characteristics with better predictive performance, when compared with downscaling without the environmental variables. Multiple realizations and uncertainty measures from simulation also provided useful information for interpretations and further environmental modeling.

  12. Modeling of episodic particulate matter events using a 3-D air quality model with fine grid: Applications to a pair of cities in the US/Mexico border

    Science.gov (United States)

    Choi, Yu-Jin; Hyde, Peter; Fernando, H. J. S.

    High (episodic) particulate matter (PM) events over the sister cities of Douglas (AZ) and Agua Prieta (Sonora), located in the US-Mexico border, were simulated using the 3D Eulerian air quality model, MODELS-3/CMAQ. The best available input information was used for the simulations, with pollution inventory specified on a fine grid. In spite of inherent uncertainties associated with the emission inventory as well as the chemistry and meteorology of the air quality simulation tool, model evaluations showed acceptable PM predictions, while demonstrating the need for including the interaction between meteorology and emissions in an interactive mode in the model, a capability currently unavailable in MODELS-3/CMAQ when dealing with PM. Sensitivity studies on boundary influence indicate an insignificant regional (advection) contribution of PM to the study area. The contribution of secondary particles to the occurrence of high PM events was trivial. High PM episodes in the study area, therefore, are purely local events that largely depend on local meteorological conditions. The major PM emission sources were identified as vehicular activities on unpaved/paved roads and wind-blown dust. The results will be of immediate utility in devising PM mitigation strategies for the study area, which is one of the US EPA-designated non-attainment areas with respect to PM.

    Full Text Available Objective: To reveal the environmental risk of pesticide prescribed in a border region between the Amazon and Platinum Basins, at the turn of the 21st century. Methods: The study used data of agronomic prescriptions for pesticides issued in the biennium of 1999-2000 in 24 cities located in a border region between the Amazon and Platinum Basins, Mato Grosso, Brazil. Results: The most widely used pesticides in the study region are class II (very dangerous and III (dangerous in number of prescriptions (N = 2,828, 86.8% andquantity prescribed (N = 344,765, 90.4%. Among class III pesticides, a strong inversion was observed in the number of prescriptions (N = 1,274; 39.1% and quantity prescribed (N = 237,319; 62.2%, indicating a lower number of prescriptions, but with higher amountprescribed. The proportion of prescriptions for products amid the various classes of Potential of Environmental Dangers (PPA ranking model, apllied in Brazil changed over the two years (c2=20,814; DF=3; p < 0,01. The 10 most prescribed products (11 activecompounds were: glyphosate, 2,4-D, sulfluramid, chlorimuron ethyl, fipronil, diuron, paraquat, methamidophos, carbofuran, chlorpyrifos and lambda-cyhalothrin, and seven of them were ranked as PPA class I or II. Conclusions: The ratio between the number of pesticide prescriptions and the quantities prescribed among the various classes of PPA showed alteration over crop years. The most reported products in this border region were classified as the most dangerous ones, with diverse mechanisms of action and potential risksto living organisms. This suggests the need to define specific policies and carefully designed strategies to prevent environmental disaster in this region.

    2010-05-01

    The Environmental Health/Home Safety Education Project (Proyecto de Salud Ambiental y Seguridad en el Hogar) has been developed in response to a wide array of severe and often preventable environmental health issues occurring in and around homes on the U.S.-Mexico border. Utilizing well-trained community members, called promotoras , homes are visited and assessed for potential environmental hazards, including home fire and food safety issues. Data analyzed from project years 2002 to 2005 shows a significant impact in knowledge levels and initial behavior change among targeted participants as it relates to fire and food safety issues. Since the initiation of the project in 1999, hundreds of participants have improved their quality of life by making their homes safer. The project has proven to be sustainable, replicable, flexible, and attractive to funders.

    Historically, international borders were located far from the major political and economic capitals of their countries and rarely received adequate planning or infrastructure development. Today, as a result of global economics and increased movement of goods between nations, border regions play a much greater role in commerce, tourism, and transportation. For example, Mexico is the second largest destination for United States exports (Woodrow Wilson Center Mexico Institute, 2009). The rapid population and economic growth along the United States–Mexican border, undocumented human border crossings, and the unique natural diversity of resources in the Borderlands present challenges for border security and environmental protection. Assessing risks and implementing sustainable growth policies to protect the environment and quality of life greatly increase in complexity when the issues cross an international border, where social services, environmental regulations, lifestyles, and cultural beliefs are unique for each country. Shared airsheds, water and biological resources, national security issues, and disaster management needs require an integrated binational approach to assess risks and develop binational management strategies.

    1992-04-01

    This Environmental Assessment documents the analysis of alternative corridors for development and operation of a proposed 115 kilovolt transmission line using private lands and transporting power to the US-Mexico international border. The project will require (1) an amendment to El Paso Electric Company`s existing export authorization to transfer power across this border, and (2) a Presidential Permit for construction of the transmission line. The project would be located in Dona Ana county in southern New Mexico, approximately five miles west of El Paso, Texas. The alternative corridors, specific locations within those corridors, and structure types are identified and analyzed in the environmental studies.

  17. Research and in situ conservation of owl monkeys enhances environmental law enforcement at the Colombian-Peruvian border.

    2014-07-01

    This study reports on impacts of illegal trade in owl monkeys (Aotus nancymaae, A. vociferans) for the biomedical research market in the Colombian-Peruvian Amazonian border. Through freedom of information requests and interviews with hunters we found that 912 owl monkeys, including A. nancymaae captured in Peru, were trapped over a 3-month period in 2012 to supply a malaria research facility based in Leticia, Colombia, which had trapping permits for the use of only 800 A. vociferans annually yet experimentation took place using A. nancymaae. High levels of extraction in Peru have had population-level impacts with significantly lower densities of Aotus spp. (3-24 individuals/km(2)) compared to Colombian sites with low hunting pressure (26-44 individuals/km(2)). Post-experimental release of this species in Colombian territory has created a new distribution whose status and impacts on resident populations of A. vociferans remain unknown. The trapping method has also had environmental impact, with loss of over 65,000 trees (including sleeping sites), annually. As Aotus species are registered under the Convention of International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix II, international trade requires official permission and evidence that extraction does not impact wild populations. However, no official records exist and CITES legislation has failed, due principally to a lack of appropriate monitoring by national authorities responsible for compliance. Of further concern is that we had previously documented and reported the illegal trade to the appropriate governmental authorities yet still no action was taken-as demonstrated by the continuing trade in 2013. Enforcement eventually occurred when a non-governmental organization initiated legal action against organizations responsible. A successful second instance ruling by the Colombian State's Council in 2013 revoked trapping permits. Using the trade in owl monkeys as a case study we consider

    A vast number of coal refuse ponds represent a significant economical resource base that are also considered to be environmentally harmful. Significant amounts of cleanable fine coal generally exist in the refuse ponds due to the inability of conventional technologies to effectively separate the fine coal from the associated gangue particles. In addition, acid generation, generally a result of pyrite oxidation, has potential to adversely affect the surrounding environment. An integrated processing strategy of simultaneously recovering high quality coal and pyrite-rich products from the treatment of a coal refuse pond slurry has been successfully evaluated using an advanced physical cleaning circuit. A clean coal product having ash and pyritic sulfur contents of 10.1% and 0.41% was recovered with a mass yield of nearly 49%. In addition, a pyrite-rich product containing nearly 83% of the coal pyrite particles present in the refuse pond material was generated for neutralization purposes for the environmental remediation of the slurry pond. 4 refs.

  19. Genes and environment - striking the fine balance between sophisticated biomonitoring and true functional environmental genomics.

    2008-08-01

    This article provides an overview how the application of the gene profiling (mainly via microarray technology) can be used in different organisms to address issues of environmental importance. Only recently, environmental sciences, including ecotoxicology, and molecular biology have started to mutually fertilize each other. This conceptual blend has enabled the identification of the interaction between molecular events and whole animal and population responses. Likewise, striking the fine balance between biomonitoring and functional environmental genomics will allow legislative and administrative measures to be based on a more robust platform. The application of DNA microarrays to ecotoxicogenomics links ecotoxicological effects of exposure with expression profiles of several thousand genes. The gene expression profiles are altered during toxicity, as either a direct or indirect result of toxicant exposure and the comparison of numerous specific expression profiles facilitates the differentiation between intoxication and true responses to environmental stressors. Furthermore, the application of microarrays provides the means to identify complex pathways and strategies that an exposed organism applies in response to environmental stressors. This review will present evidence that the widespread phenomenon of hormesis has a genetic basis that goes beyond an adaptive response. Some more practical advantages emerge: the toxicological assessment of complex mixtures, such as effluents or sediments, as well as drugs seems feasible, especially when classical ecotoxicological tests have failed. The review of available information demonstrates the advantages of microarray application to environmental issues spanning from bacteria, over algae and spermatophytes, to invertebrates (nematode Caenorhabditis elegans, crustacea Daphnia spp., earthworms), and various fish species. Microarrays have also highlighted why populations of a given species respond differently to similar

  20. Environmental injustice along the US-Mexico border: residential proximity to industrial parks in Tijuana, Mexico

    2015-09-01

    Research in the Global North (e.g., US, Europe) has revealed robust patterns of environmental injustice whereby low income and minority residents face exposure to industrial hazards in their neighborhoods. A small body of research suggests that patterns of environmental injustice may diverge between the Global North and South due to differing urban development trajectories. This study uses quantitative environmental justice methods to examine spatial relationships between residential socio-demographics and industrial parks in Tijuana, Baja California Norte, Mexico using 2010 census data for Tijuana’s 401 neighborhoods and municipality-provided locations of industrial parks in the city. Results of spatial lag regression models reveal that formal development is significantly associated with industrial park density, and it accounts for the significant effect of higher socioeconomic status (measured using mean education) on greater industrial density. Higher proportions of female-headed households are also significantly associated with industrial park density, while higher proportions of children and recent migrants are not. The formal development findings align with other studies in Mexico and point to the importance of urban development trajectories in shaping patterns of environmental injustice. The risks for female-headed households are novel in the Mexican context. One potential explanation is that women factory workers live near their places of employment. A second, albeit counterintuitive explanation, is the relative economic advantage experienced by female-headed households in Mexico.

  1. The Border Environmental Health Initiative: Investigation of the Transboundary Santa Cruz Watershed

    2009-12-01

    In the borderland region of the desert southwest, human health and the ecosystems upon which humans rely largely depend on the quality, quantity, and distribution of water resources. In the Santa Cruz River Watershed (SCW), located in the Arizona and Sonora, Mexico border region, surface water is scarce and unreliable, and, during much of the year, is composed of effluent from the local wastewater treatment plant. This makes groundwater the preferred and, consequently, primary source for industrial, agricultural, and domestic use. USGS scientists are using an integrative approach, incorporating the expertise of the Geography, Water, Biology, and Geology disciplines to identify risks to water resources in the SCW, and the potential for impacts to riparian ecosystems and ultimately, human health. This includes tracking organic and inorganic contaminants and their effects from sources to sinks in sediment, water, plants, and animals. Existing ground- and surface-water models will be used and modified to assess contaminant and sediment transport. Water quality, sediment, aquatic macro invertebrates, aquatic plants (macrophytes), algae, riparian grasses, fish, and birds will be sampled at five locations along the Santa Cruz River. Field sampling data will be obtained at sites that coincide with historical sampling programs. Site locations include (i.) the Santa Cruz River headwaters (which should be unaffected by downstream contaminant sources), (ii.) a tributary routed through an abandoned mining district, (iii.) a binational tributary that flows though highly urbanized areas, (iv.) effluent from the local wastewater treatment plant, and (v.) the downstream confluence of the first four sources. The Soil and Water Assessment Tool (SWAT) model will be used in combination with field data to identify key sources of contaminants, contributing areas, and transport modes to track their movement to surface waters. These data will be used together to test relationships between

    The objective of this issue of Articulo – Journal of Urban Research is to examine the characteristics of border markets in a comparative perspective. In this introductory paper, I first discuss what makes African border markets different from other markets, and examine several factors that explain...... their unequal economic development: the presence of a trade community, the combination of trading and productive activities, and the relative porosity of borders. In a second part, I examine how border markets on the U.S.-Mexico border must simultaneously guarantee the security of the state while favoring...... regional trade. The last part of the paper argues that more policy attention should be paid to border markets which, despite being at the margin of states, are a vital component of their economy.

    1990-01-01

    This report deals with a special area of the Eastern European disaster, cross-border environmental damage. It can be seen at various sites and/or large projects: Rumanian-Bulgarian squabbles over Rumanian chlorine clouds that drift across the Danube to Bulgaria; Hungarian-Czechoslovakian disagreements about the power-station on the Danube, Gabcikovo-Nagymaros; Polish-Czechoslovakian arguments about coke-works and dangerous refuse dumps in the immediate vicinity of the border or competition in the efforts to offer themselves as terminal storage area for Western exporters of dangerous refuse. The most obvious quality that the projects described had in common was their choice of location. Taking into account wind direction, river currents, proximity to borders etc. they were all so located that their own country would necessarily receive the benefit from them but the neighbouring country would get all the environmental pollution. The future can only get better - not only because it could hardly get any worse. Now that there have been 'changes', 'gentle revolutions' etc. in all the affected countries and the actual originators of the depicted environmental offences have been deposed, there is some room for cautious optimism.

    Previous studies have shown that variations in environmental conditions play a major role in explaining variations in plant species richness at community and landscape scales. In this study, we considered the degree to which fine-scale spatial variations in richness could be related to fine-scale variations in abiotic and biotic factors. To examine spatial variation in richness, grids of 1 m(2) plots were laid out at five sites within a coastal riverine wetland landscape. At each site, a 5 x 7 array of plots was established adjacent to the river's edge with plots one meter apart. In addition to the estimation of species richness, environmental measurements included sediment salinity, plot microelevation, percent of plot recently disturbed, and estimated community biomass. Our analysis strategy was to combine the use of structural equation modeling (path modeling) with an assessment of spatial association. Mantel's tests revealed significant spatial autocorrelation in species richness at four of the five sites sampled, indicating that richness in a plot correlated with the richness of nearby plots. We subsequently considered the degree to which spatial autocorrelations in richness could be explained by spatial autocorrelations in environmental conditions. Once data were corrected for environmental correlations, spatial autocorrelation in residual species richness could not be detected at any site. Based on these results, we conclude that in this coastal wetland, there appears to be a fine-scale mapping of diversity to microgradients in environmental conditions.

    Full Text Available The language of poetry is a language of inquiry, not the language of a genre. Poetry has the capacity of entering those zones known as borderlands, where you meet strange things and foreign people. In this poetic world view, the border is not an edge along the fringe of lands, societies and experiences, but rather their very middle – and their in-between. The structures of language are social structures in which meanings and intentions are already in place, always fighting for power and dominance, with rhetorical figures and more violent weapons.

    This study proposes global threat scores to prioritize the harmfulness of anthropogenic fine and ultrafine metallic particles (FMP) emitted into the atmosphere at the global scale. (Eco)toxicity of physicochemically characterized FMP oxides for metals currently observed in the atmosphere (CdO, CuO, PbO, PbSO{sub 4}, Sb{sub 2}O{sub 3}, and ZnO) was assessed by performing complementary in vitro tests: ecotoxicity, human bioaccessibility, cytotoxicity, and oxidative potential. Using an innovative methodology based on the combination of (eco)toxicity and physicochemical results, the following hazard classification of the particles is proposed: CdCl{sub 2}∼CdO>CuO>PbO>ZnO>PbSO{sub 4}>Sb{sub 2}O{sub 3}. Both cadmium compounds exhibited the highest threat score due to their high cytotoxicity and bioaccessible dose, whatever their solubility and speciation, suggesting that cadmium toxicity is due to its chemical form rather than its physical form. In contrast, the Sb{sub 2}O{sub 3} threat score was the lowest due to particles with low specific area and solubility, with no effects except a slight oxidative stress. As FMP physicochemical properties reveal differences in specific area, crystallization systems, dissolution process, and speciation, various mechanisms may influence their biological impact. Finally, this newly developed and global approach could be widely used in various contexts of pollution by complex metal particles and may improve risk management. - Highlights: • Seven micro- and nano- monometallic characterized particles were studied as references. • Bioaccessibility, eco and cytotoxicity, and oxidative potential assays were performed. • According to calculated threat scores: CdCl{sub 2}∼CdO>CuO>PbO>ZnO>PbSO{sub 4}>Sb{sub 2}O{sub 3}.

    Lithium aluminosilicate(LAS) glass-ceramics with a few gas bubbles were prepared when SnO2, V2O5 and CeO2 were used as fining agents. The effect of the complex fining agent on the crystallization, phase compositions and microstructure of LAS glass–ceramics was investigated by differential thermal analysis, X-ray diffraction and scanning electron microscopy, respectively. The results show that the introduction of fining agents promotes the crystallization at a lower temperature and has little effect on the compositions of main crystalline phase and microstructure when the crystalline phase remains β-quartz. The special colors of LAS glass-ceramics can be obtained by controlling the crystallization temperature and the amounts of V2O5 and CeO2. The complex fining agent is an environmentally friendly alternative to toxic As2O3 and can be also used as a colorant for colored LAS glass-ceramics.

    X-ray Absorption Fine Structure spectroscopy was used to probe the speciation of the ppm level Pu in thirteen soil and concrete samples from the Rocky Flats Environmental Technology Site in support of the site remediation effort that has been successfully completed since these measurements. In addition to X-ray Absorption Near Edge Spectra, two of the samples yielded Extended X-ray Absorption Fine Structure spectra that could be analyzed by curve-fits. Most of these spectra exhibited features consistent with PU(IV), and more specificaJly, PuO{sub 2+x}-type speciation. Two were ambiguous, possibly indicating that Pu that was originally present in a different form was transforming into PuO{sub 2+x}, and one was interpreted as demonstrating the presence of an unusual Pu(VI) compound, consistent with its source being spills from a PUREX purification line onto a concrete floor and the resultant extreme conditions. These experimental results therefore validated models that predicted that insoluble PuO{sub 2+x} would be the most stable form of Pu in equilibrium with air and water even when the source terms were most likely Pu metal with organic compounds or a Pu fire. A corollary of these models' predictions and other in situ observations is therefore that the minimal transport of Pu that occurred on the site was via the resuspension and mobilization of colloidal particles. Under these conditions, the small amounts of diffusely distributed Pu that were left on the site after its remediation pose only a negligible hazard.

    Full Text Available The creation of extractive, agro-industrial and ecological spaces in indigenous territories raises a series of questions regarding the future of these territories and, particularly, the indigenous project of territorial and political autonomy in Latin America and elsewhere. These spaces are first of all social spaces, crossed and interwoven by power relations that define mobile frontiers between life and death, domination and autonomy, inclusion and exclusion. This paper deals with the situation of the Awá people and their territory in Ecuador, in a context of growing territorial and environmental pressures from the state, logging, mining, and palm-oil companies, as well as from the growing interest and actions regarding the conservation of its “nature”.

    In low-grade banded iron formations (BIFs), a large part of the iron is related to micro- and nano- metric iron-bearing inclusions within quartz and/or carbonates, mainly dolomite (~ 20 to 50 μm). Low-grade fine grained iron ore present two types of environmental risks: a) they are often stocked as tailings. For example, the recent disaster (5th of November 2015) in the Minas Gerais district, Brazil, was caused by the collapse of the Fundão tailings dam at an open cast mine; b) during beneficiation significant amounts of dust are generated also leading to metal loss. A laminated BIF studied from a drill core at Àguas Claras Mine, Quadrilátero Ferrífero, Brazil, contains 26.71 wt. % total iron, 0.2 wt. % SiO2, 0.32 wt.% MnO, 15.46 wt. % MgO, 22.32 wt.% CaO, 0.09 wt. % P2O5, risk factors.

    with other subsystems like South East Asia may have different approaches to global governance, international constitutional order, or particular cases such as the measure of infringement of human rights when targeting individuals suspected of terrorist links. Yet international law remains the key part of the Asian and global security regime. The hypothesis of this study is that the "void of governance" regime in territorial and international waters provides lucrative environment for developing terrorism, piracy, environmental degradation, and other criminal activities that pose untraditional threats to the regional security. This "void of governance" regime can be caused by either, or both, de jure or de facto insufficient control over particular marine territories.

    In temperate coniferous forests, spatial variation in net ecosystem production (NEP) is often associated with variation in stand age and heterogeneity in environmental factors such as soil depth. However, coarse spatial resolution analyses used to evaluate the terrestrial contribution to global NEP do not generally incorporate these effects. In this study, a fine-scale (25 m grid) analysis of NEP over a 164-km2 area of productive coniferous forests in the Pacific Northwest region of the United States was made to evaluate the effects of including fine scale information in landscape-scale NEP assessments. The Enhanced Thematic Mapper (ETM+) sensor resolved five cover classes in the study area and further differentiated between young, mature and old-growth conifer stands. ETM+ was also used to map current leaf area index (LAI) based on an empirical relationship of observed LAI to spectral vegetation indices. A daily time step climatology, based on 18 years of meteorological observations, was distributed (1 km resolution) over the mountainous terrain of the study area using the DAYMET model. Estimates of carbon pools and flux associated with soil, litter, coarse woody debris and live trees were then generated by running a carbon cycle model (Biome-BGC) to a state that reflected the current successional status and LAI of each grid cell, as indicated by the remote sensing observations. Estimated annual NEP for 1997 over the complete study area averaged 230 g C m-2, with most of the area acting as a carbon sink. The area-wide NEP is strongly positive because of reduced harvesting in the last decade and the recovery of areas harvested between 1940 and 1990. The average value was greater than would be indicated if the entire area was assumed to be a mature conifer stand, as in a coarse-scale analysis. The mean NEP varied interannually by over a factor of two. This variation was 38% less than the interannual variation for a single point. The integration of process models

    Fine punishment as a kind of property punishment, contributes to prevention and punishment of environmental crime. Its particularity is that it can be used for environmental restoration, treating environmental pollution caused by environmental crime or repairing environmental damage. However, environmental criminal legislation about fine punishment has a lot of weaknesses in the provisions of the amount, the applicable way, and not distinguishing criminal intent and negligence in legislation, which lead to many difficulties in judicial application of the environmental crime penalty punishment. So, to perfect legislation of fine punishment of environmental crime, we must establish provisions of the amount and its corresponding standards, and add permitted penalty system as fine punishment of environmental crime, and the application of amount of the environmental crime penalty punishment must be based on intent or negligence.%罚金刑作为刑罚的一种,有助于环境犯罪的预防与惩治,其特殊性在于可以将其用于环境修复,使因环境犯罪行为导致的环境污染或环境破坏得到一定程度上的修复。而我国环境犯罪刑法关于罚金刑在数额的规定方式上、刑罚的适用方式上以及数额确定上未区分犯罪故意与过失等方面,存在诸多不足,导致司法机关对环境犯罪罚金刑的适用存在困难。为此,有必要通过确立环境犯罪罚金刑数额规定方式,确定相应的标准,增加易科罚金制作为环境犯罪罚金刑的适用方式,并且对于环境犯罪罚金刑数额的适用以故意与过失为基础,予以完善。

  19. «Cross-border Environmental Peace» as the Interaction of Regional Norms and Local Power: Lessons from Cross-Regional Analysis of Water Security Debates

    Directory of Open Access Journals (Sweden)

    Harlan Koff

    2017-01-01

    Full Text Available This article contends that notions of «peace» and «justice» in cross-border water management vary in different world regions. Moreover, it argues that «peace» and «justice» can be explained by analyzing the interaction between «regional» interpretations and implementation of water security norms and local cross-border power structures. «Regional water security» is defined as the normative commitment to provide necessary water resources to communities within world regions. «Power,» which is defined traditionally as «the ability of actors to obtain their objectives despite opposition» is viewed as a function of political entrepreneurialism and opportunity structures. This article derives from a review of the pertinent literatures on «water security» and «water justice,» the two elements of «water peace» as well as scholarship on cross-border water management in different world regions. It discusses water governance within the framework of cross-border politics and comparative regional integration. It also includes analysis of the policy documents and websites of seventeen regional organizations as well as interviews with key actors and local experts on water management in specific cross-border case studies. The article is divided into five sections. Following this introduction, part two examines «water security» and «water justice» in international affairs. Part III then discusses «power» in cross-border water governance debates and addresses the transnational face of water security discussions. Part IV presents a comparative examination of cross-border «water justice» in selected world regions which is followed by theoretical considerations that are addressed in part V, the conclusion. In general, the article emphasizes the need to promote comparative cross-regional research on cross-border water governance in order to examine how «peace,» «security» and «justice» are framed in debates over water resources.

    Melanoma is a fatal cancer with a growing incident rate. However it could be cured if diagnosed in early stages. The first step in detecting melanoma is the separation of skin lesion from healthy skin. There are particular features associated with a malignant lesion whose successful detection relies upon accurately extracted borders. We propose a two step approach. First, we apply K-means clustering method (to 3D RGB space) that extracts relatively accurate borders. In the second step we perform an extra refining step for detecting the fading area around some lesions as accurately as possible. Our method has a number of novelties. Firstly as the clustering method is directly applied to the 3D color space, we do not overlook the dependencies between different color channels. In addition, it is capable of extracting fine lesion borders up to pixel level in spite of the difficulties associated with fading areas around the lesion. Performing clustering in different color spaces reveals that 3D RGB color space is preferred. The application of the proposed algorithm to an extensive data-base of skin lesions shows that its performance is superior to that of existing methods both in terms of accuracy and computational complexity.

    The wetting of rough honeycomb micrometrically scaled polymer substrates was studied. A very strong dependence of the apparent contact angle on the drop volume has been established experimentally. The environmental scanning electron microscopy study of the fine structure of the triple line is reported first. The triple line is not smooth and prefers grasping the polymer matrix over air holes. The precursor rim surrounding the drop has been observed. The revealed dependence of the apparent contact angle on the drop volume is explained by the transition between the pure Cassie and combined Wenzel-Cassie wetting regimes, which is induced by capillarity penetration of water into the holes of relief.

    This study describes and demonstrates different techniques for surface fitting daily environmental hazards data of particulate matter with aerodynamic diameter less than or equal to 2.5 microm (PM2.5) for the purpose of integrating respiratory health and environmental data for the Centers for Disease Control and Prevention (CDC) pilot study of Health and Environment Linked for Information Exchange (HELIX)-Atlanta. It presents a methodology for estimating daily spatial surfaces of ground-level PM2.5 concentrations using the B-Spline and inverse distance weighting (IDW) surface-fitting techniques, leveraging National Aeronautics and Space Administration (NASA) Moderate Resolution Imaging Spectrometer (MODIS) data to complement U.S. Environmental Protection Agency (EPA) ground observation data. The study used measurements of ambient PM2.5 from the EPA database for the year 2003 as well as PM2.5 estimates derived from NASA's satellite data. Hazard data have been processed to derive the surrogate PM2.5 exposure estimates. This paper shows that merging MODIS remote sensing data with surface observations of PM,2. not only provides a more complete daily representation of PM,2. than either dataset alone would allow, but it also reduces the errors in the PM2.5-estimated surfaces. The results of this study also show that although the IDW technique can introduce some numerical artifacts that could be due to its interpolating nature, which assumes that the maxima and minima can occur only at the observation points, the daily IDW PM2.5 surfaces had smaller errors in general, with respect to observations, than those of the B-Spline surfaces. Finally, the methods discussed in this paper establish a foundation for environmental public health linkage and association studies for which determining the concentrations of an environmental hazard such as PM2.5 with high accuracy is critical.

    Roots of many plants are known to produce large numbers of 'border' cells that play a central role in root protection and the interaction of the root with the rhizosphere. Unlike border cells, border-like cells were described only recently in the model plant Arabidopsis thaliana and other Brassicaceae species and very little is known about the functional properties of border-like cells as compared with 'classical' border cells. To stimulate discussion and future research on this topic, the function of border cells and the way border-like cells are organized, maintained, and possibly involved in plant protection is discussed here.

    2011-01-01

    Full Text Available This essay reads two Asian nature-oriented films from the perspective of ecocinecriticism,an ecologically minded film criticism. Plant Wars, produced by PTSTaiwan, questions the demarcation between native plants and exotic plants as well asbetween plants and human beings so as to remap the in-between border area. Thestorytelling method it applies is to feature 14 currently native plants as the maincharacters, and illustrates their relationship to aboriginal people, farmers, beekeepersand to other insect species. Bird Without Borders, also produced by PTS, tells the storyof the migration journey of a group of black-faced spoonbills flying 16,000 kilometersall the way from Tainan, Taiwan, to Japan, along the border of South and North Korea,to a remote island of China to look for feeding places and then back to Taiwan to spendthe winter. Different layers of border-crossing are shown in Bird. One similarity ofthese two PTS productions is the search for border-crossing so as to redefine or revisewhat the border means. Plant questions the biological categorization of the native plantsand the exotic plants; Bird illustrates how the crew physically follows the route of thebirds’ flight which crosses the national borders to provide a vision of remapping thenatural territory through challenging the idea of a fixed “place.” Both are seeking forways to trespass the man-made borders: Plant via environmental imagination; Bird viasome physical movement. While the title of Plant Wars seemingly expresses its positionmore strongly through “wars,” Bird Without Borders explicitly asserts a dream of noborders.

    2007-01-01

    Plant roots release a large number of border cells into the rhizosphere, which are believed to play a key role in root development and health. The formation and loss of these cells from the root cap region is a developmentally regulated process that is also controlled by phytohormones and environmental factors. The separation of border cells involves the complete dissociation of individual cells from each other and from root tissue. This process requires the activity of cell wall-degrading enzymes that solubilize the cell wall connections between cells. We present and discuss the solubilization process with an emphasis on pectin-degrading enzymes as well as the recently discovered root border-like cells of Arabidopsis thaliana.

    of confrontation between divergent political ideologies. In the majority of the Southeast Asian borderlands, this implied violent disruption in the lives of local borderlanders that came to affect their relationship to their nation-state. A case in point is the ethnic Iban population living along the international...... border between the Indonesian province of West Kalimantan and the Malaysian state of Sarawak on the island of Borneo. Based on local narratives, the aim of this paper is to unravel the little known history of how the Iban segment of the border population in West Kalimantan became entangled in the highly...... militarized international disputes with neighbouring Malaysia in the early 1960s, and in subsequent military co-operative ‘anti-communist’ ‘counter-insurgency’ efforts by the two states in the late 1960–1970s.

  20. Metrics for border management systems.

    Energy Technology Data Exchange (ETDEWEB)

    Duggan, Ruth Ann

    2009-07-01

    There are as many unique and disparate manifestations of border systems as there are borders to protect. Border Security is a highly complex system analysis problem with global, regional, national, sector, and border element dimensions for land, water, and air domains. The complexity increases with the multiple, and sometimes conflicting, missions for regulating the flow of people and goods across borders, while securing them for national security. These systems include frontier border surveillance, immigration management and customs functions that must operate in a variety of weather, terrain, operational conditions, cultural constraints, and geopolitical contexts. As part of a Laboratory Directed Research and Development Project 08-684 (Year 1), the team developed a reference framework to decompose this complex system into international/regional, national, and border elements levels covering customs, immigration, and border policing functions. This generalized architecture is relevant to both domestic and international borders. As part of year two of this project (09-1204), the team determined relevant relative measures to better understand border management performance. This paper describes those relative metrics and how they can be used to improve border management systems.

    The Indo-Gangetic Plains (IGP) in northern South Asia are among the most polluted and most densely populated places in the world, and they are upwind of vulnerable ecosystems in the Himalaya mountains. They are also fragmented across 5 countries between which movement of people, data, instruments and scientific understanding have been very limited. ICIMOD's Atmosphere Initiative has for the past three years been working on filling data gaps in the region, while facilitating collaborations across borders. It has established several atmospheric observatories at low and mid elevations in Bhutan and Nepal that provide new data on the inflow of pollutants from the IGP towards the mountains, as well as quantify the effects of local emissions on air quality in mountain cities. EGU will be the first international conference where these data will be presented. ICIMOD is in the process of setting up data servers through which data from the region will be shared with scientists and the general public across borders. Meanwhile, to promote cross-border collaboration among scientists in the region, while addressing an atmospheric phenomenon that affects the lives of the several hundred million people, ICIMOD' Atmosphere Initiative has been coordinating an interdisciplinary multi-year study of persistent winter fog over the Indo-Gangetic Plains, with participation by researchers from Pakistan, India, China, Nepal, Bhutan and Bangladesh. Using a combination of in-situ measurements and sample collection, remote sensing, modeling and community based research, the researchers are studying how changing moisture availability and air pollution have led to increases in fog frequency and duration, as well as the fog's impacts on local communities and energy demand that may affect air pollution emissions. Preliminary results of the Winter 2015-2016 field campaign will be shown.

    . Pools of standing rain water on impermeable soils can become ideal habitats for mosquito ovipositing and larval development between storms, which in turn can pose a higher risk for infection to humans and livestock animals. Because clay and other fine-grained minerals strongly affect a soil’s physical and chemical properties such as porosity, permeability and surface sealing/crusting upon saturation, 211 soil samples were collected at approximately 3-5 km sample spacing. The mineralogy of both the soils that are prone to ponding of standing water after storms. Our results show the utility of using remote sensing observations for mapping flood prone areas that may pose mosquito related health threats to both people and livestock on both sides of the border.

The challenge at the American College of Cardiology (ACC) and anywhere else in the world is to hold patient care above the artificial barriers raised by geopolitical issues. Fundamentally, the goal of ACC members or of any cardiology societies in the world is to provide excellent patient care. Cardiovascular disease is essentially the same throughout the world. Where there are minor variations among individuals, as clinicians we find priceless opportunity to learn.

    Full Text Available Libraries are fundamental institutions for the life under socialism in Bulgaria (1944-1989. They provide studies and readings for big part of society. This is time when television was very rare in Bulgarian homes and the newspapers were totally controlled by Communist party. This way a library served as the main source of information. Seemingly ordinary cultural centers, they become a powerful tool in the hands of the communist state. They are the ones who are actively worked to impose new socialist thinking trough setting limits on access to readers and therefore control the flow of information. The aim of this article is to trace the influence of restricted by communist censorship institution Glavlit literature. Or to put it another way – what was the role of censorship in the process of establishment of borders created by prohibited access to scientific information.

  9. Border mythology: Turner and modernity

    Full Text Available Modernity has been creating spaces, new boundaries and borders, as metaphysical, mythological and symbolic marks of physical and imaginary territories. Modern space and its borders are metaphors, boundaries that are created, walls that rise to identify with some and categorize others. In this short paper we want to approach the problem of the transformation of the idea of border (geographical, cultural, symbolic, etc., for a reflection on the transformations of that civilized obsession called border. The border has always been a reference in facing the identities, names, symbols, different imaginary: it is more confrontational line between two otherness. From the previous framework, we reflect on Turnerian mythology, as we believe that behind the creation of the imagination of the northern border is the mythical vision of the American frontier as ideological canon that explains and confirms the presence of the white race in a border re–made in the image and likeness of the “American Dream”. Frederick Turner’s reflection on the role of the frontier in American history is not only the study of the importance of progress towards the West but –even more so, is the analysis of meaning that had the American frontier as a historical process that ended in 1893, as Turner said, but rather extended into the twentieth century and continues to constantly shaping the process of territorialization of the border.

    2008-09-01

    Full Text Available During the different ages of history and prehistory, borders have possessed different kinds of natures. Sometimes they did not exist, at other times they have been very diffuse, while at others they have been impassable. There were no borders in the Paleolithic age, or during Greece’s Heroic Age. It was not until the creation of the city-states and the empires that borders began to be consolidated. Territorial demarcations were not very strict during the Middle Ages, either. It was in the modern age that borders acquired an impassable nature, following the birth of the modern State, and they began to weaken with the crisis of the modern State that began in the 20th century. Thus, the author claims, the construction of borders is not a fundamentally political-administrative event. Instead, it seems to be primarily a phenomenon of a cultural nature and, more specifically, of a metaphysical nature.

    2005-01-01

    Fire knows no borders and neither should the tools for fighting it. It was with this aim in mind that delegates from 14 different countries came to CERN at the beginning of April to take part in the twentieth of a series of twice-yearly international conferences organised by the Federation of European Union Fire Officer Associations (FEU). This latest conference allowed participants to keep abreast of new developments with a view to improving the safety techniques used in their own countries. The first in the series was held in Tampere, Finland, in 1994. The FEU network's objective is to harmonise safety policies and modernise the fire-fighting programme. In particular, it aims to develop an international system for testing hotels' fire alarm systems and to improve language learning in all countries' fire-fighting services.

    2008-01-01

    As part of the U.S. National Environmental Public Health Tracking Network (EPHTN), the National Center for Environmental Health (NCEH) at the U.S. Centers for Disease Control and Prevention (CDC) led a project in collaboration with the National Aeronautics and Space Administration (NASA) Marshall Space Flight Center (MSFC) called Health and Environment Linked for Information Exchange (HELIX-Atlanta). Under HELIX-Atlanta, pilot projects were conducted to develop methods to better characterize exposure; link health and environmental datasets; and analyze spatial/temporal relationships. This paper describes and demonstrates different techniques for surfacing daily environmental hazards data of particulate matter with aerodynamic diameter less than or equal to 2.5 micrometers (PM(sub 2.5) for the purpose of integrating respiratory health and environmental data for the CDC's pilot study of HELIX-Atlanta. It describes a methodology for estimating ground-level continuous PM(sub 2.5) concentrations using spatial surfacing techniques and leveraging NASA Moderate Resolution Imaging Spectrometer (MODIS) data to complement the U.S. Environmental Protection Agency (EPA) ground observation data. The study used measurements of ambient PM(sub 2.5) from the EPA database for the year 2003 as well as PM(sub 2.5) estimates derived from NASA's MODIS data. Hazard data have been processed to derive the surrogate exposure PM(sub 2.5) estimates. The paper has shown that merging MODIS remote sensing data with surface observations of PM(sub 2.5), may provide a more complete daily representation of PM(sub 2.5), than either data set alone would allow, and can reduce the errors in the PM(sub 2.5) estimated surfaces. Future work in this area should focus on combining MODIS column measurements with profile information provided by satellites like the National Polar-orbiting Operational Environmental Satellite System (NPOESS).

    This study describes and demonstrates different techniques for surfacing daily environmental / hazards data of particulate matter with aerodynamic diameter less than or equal to 2.5 micrometers (PM2.5) for the purpose of integrating respiratory health and environmental data for the Centers for Disease Control and Prevention (CDC s) pilot study of Health and Environment Linked for Information Exchange (HELIX)-Atlanta. It described a methodology for estimating ground-level continuous PM2.5 concentrations using B-Spline and inverse distance weighting (IDW) surfacing techniques and leveraging National Aeronautics and Space Administration (NASA) Moderate Resolution Imaging Spectrometer (MODIS) data to complement The Environmental Protection Agency (EPA) ground observation data. The study used measurements of ambient PM2.5 from the EPA database for the year 2003 as well as PM2.5 estimates derived from NASA s satellite data. Hazard data have been processed to derive the surrogate exposure PM2.5 estimates. The paper has shown that merging MODIS remote sensing data with surface observations of PM2.5 not only provides a more complete daily representation of PM2.5 than either data set alone would allow, but it also reduces the errors in the PM2.5 estimated surfaces. The results of this paper have shown that the daily IDW PM2.5 surfaces had smaller errors, with respect to observations, than those of the B-Spline surfaces in the year studied. However the IDW mean annual composite surface had more numerical artifacts, which could be due to the interpolating nature of the IDW that assumes that the maxima and minima can occur only at the observation points. Finally, the methods discussed in this paper improve temporal and spatial resolutions and establish a foundation for environmental public health linkage and association studies for which determining the concentrations of an environmental hazard such as PM2.5 with good accuracy levels is critical.

    2017-03-29

    The 'neural plate border' of vertebrate embryos contains precursors of neural crest and placode cells, both defining vertebrate characteristics. How these lineages segregate from neural and epidermal fates has been a matter of debate. We address this by performing a fine-scale quantitative temporal analysis of transcription factor expression in the neural plate border of chick embryos. The results reveal significant overlap of transcription factors characteristic of multiple lineages in individual border cells from gastrula through neurula stages. Cell fate analysis using a Sox2 (neural) enhancer reveals that cells that are initially Sox2+ cells can contribute not only to neural tube but also to neural crest and epidermis. Moreover, modulating levels of Sox2 or Pax7 alters the apportionment of neural tube versus neural crest fates. Our results resolve a long-standing question and suggest that many individual border cells maintain ability to contribute to multiple ectodermal lineages until or beyond neural tube closure.

    2013-11-01

    Boundary effect analysis is related to border policy making in the cross-border ethnic area. The border effect literatures show that geographic boundaries have obvious impacts on economic, social and cultural relations in both sides of a nation border. Particularly in cross-border ethnic areas, each ethnic group has strong internal spatial structure relevance, and the boundary effect is more obvious. However, most of China's border areas are cross-border ethnic areas, each of border issues is unique. Under this perspective, we analyze the border effects of various boundaries can provide basis for formulating border management policies. For small scale of cross-border ethnic minority areas, how to formulate the boundary management policy is a good question to explore. This paper is demonstrated by a study of the impact of border management policies in Dehong Dai and Jingpo Autonomous Prefecture in Yunnan Province at the border area to Burma. The comparative method is used to analysis the border management policies in past 50 decades for the border area of Yunnan Province .This research aims to define trends within border policy and its influences to national security. This paper also examines Wendy Brown's liberal theory of border management policy. We found that it is not suitable for Sino-Burma border area. The conclusion is that the changes or instability of international economic and political situation has more influence to this cross-border ethnic area, and only innovative policy will be effective in cross-border ethnic area. So the border management policies should reflect the change of international context.

  9. Old Borders and New Bordering Capabilities: Cities as Frontier Zones

    Directory of Open Access Journals (Sweden)

    Saskia Sassen

    2015-12-01

    Full Text Available The global city is a new frontier zone. Deregulation, privatization, and new fiscal and monetary policies create the formal instruments to construct their equivalent of the old military “fort”. The city is also a strategic frontier zone for those who lack power, and allows the making of informal politics. At the same time the border is a mix of regimes, marked by protections and opportunities for corporations and high-level professionals, and implies confinement, capture and detention for migrants. The essay discusses the transformation of the city in a frontier zone and analyses the separation between the capabilities entailed by territoriality and the geographic territory tout court. The analysis focuses on the effects of neoliberal policies that, far from making this a borderless world, have actually multiplied the bordered spaces that allow firms and markets to move across conventional borders. Cities are therefore one of the key sites where new neoliberal norms are made and where new identities emerge.

    Couture, V; Drouin, R; Tan, S-L; Moutquin, J-M; Bouffard, C

    2015-01-01

    The purpose of this review is to synthesize the current knowledge on the international movement of patients and biopsied embryo cells for pre-implantation genetic diagnosis and its different applications. Thus far, few attempts have been made to identify the specific nature of this phenomenon called 'cross-border reprogenetic services'. There is scattered evidence, both empirical and speculative, suggesting that these services raise major issues in terms of service provision, risks for patients and the children-to-come, the legal liabilities of physicians, as well as social justice. To compile this evidence, this review uses the narrative overview protocol combined with thematic analysis. Five major themes have emerged from the literature at the conjunction of cross-border treatments and reprogenetics: 'scope', 'scale', 'motivations', 'concerns', and 'governance'. Similar themes have already been observed in the case of other medical tourism activities, but this review highlights their singularity with reprogenetic services. It emphasizes the diagnostic and autologous feature of reprogenetics, the constant risk of misdiagnosis, the restriction on certain tests for medically controversial conditions, and the uncertain accessibility of genetic counseling in cross-border settings.

  14. Refining borders of genome-rearrangements including repetitions

    Full Text Available Abstract Background DNA rearrangement events have been widely studied in comparative genomic for many years. The importance of these events resides not only in the study about relatedness among different species, but also to determine the mechanisms behind evolution. Although there are many methods to identify genome-rearrangements (GR, the refinement of their borders has become a huge challenge. Until now no accepted method exists to achieve accurate fine-tuning: i.e. the notion of breakpoint (BP is still an open issue, and despite repeated regions are vital to understand evolution they are not taken into account in most of the GR detection and refinement methods. Methods and results We propose a method to refine the borders of GR including repeated regions. Instead of removing these repetitions to facilitate computation, we take advantage of them using a consensus alignment sequence of the repeated region in between two blocks. Using the concept of identity vectors for Synteny Blocks (SB and repetitions, a Finite State Machine is designed to detect transition points in the difference between such vectors. The method does not force the BP to be a region or a point but depends on the alignment transitions within the SBs and repetitions. Conclusion The accurate definition of the borders of SB and repeated genomic regions and consequently the detection of BP might help to understand the evolutionary model of species. In this manuscript we present a new proposal for such a refinement. Features of the SBs borders and BPs are different and fit with what is expected. SBs with more diversity in annotations and BPs short and richer in DNA replication and stress response, which are strongly linked with rearrangements.

  15. Living in a High Mountain Border Region: the Case of the 'Bhotiyas' of the Indo-Chinese Border Region

    2008-01-01

    This article introduces one of South Asia's most important border regions into academic discourse, namely, the Central Himalayan mountain rim separating India and the Tibetan Autonomous Region (People's Republic of China). What makes this border region so interesting is a tangled interplay of changing environmental, cultural, and political forms to which the local populations constantly have to adapt in order to make a living there. We focused on the so-called 'Bhotiyas' of Uttarakhand, former trans-Himalayan traders whose ethnicity and livelihood was traditionally associated with the Indo-Chinese border that was sealed as a result of the India-China war in 1962. Drawing on the work of borderland scholarship, we identified the key processes and developments that changed the perspective of this area. Competing political aspirations as well as the 'Bhotiyas' countervailing strategies were considered equally important for understanding local livelihoods and identities within the dynamics of a 'high mountain border region'. Through an exemplary analysis of historical differences of power in one 'Bhotiya' valley, we further explored the ways in which shifting socio-spatial constellations are creatively re-interpreted by the borderlanders.

In spite of the differentiated historical construction of national identities, according to a literature review, it could be argued that there is an unprecedented border relation between these three countries. Furthermore, it is possible to conclude that this non-violent strategy has been successful in the last 15 years.

  19. Phenotypic covariance at species’ borders

    Science.gov (United States)

    2013-01-01

    Background Understanding the evolution of species limits is important in ecology, evolution, and conservation biology. Despite its likely importance in the evolution of these limits, little is known about phenotypic covariance in geographically marginal populations, and the degree to which it constrains, or facilitates, responses to selection. We investigated phenotypic covariance in morphological traits at species’ borders by comparing phenotypic covariance matrices (P), including the degree of shared structure, the distribution of strengths of pair-wise correlations between traits, the degree of morphological integration of traits, and the ranks of matricies, between central and marginal populations of three species-pairs of coral reef fishes. Results Greater structural differences in P were observed between populations close to range margins and conspecific populations toward range centres, than between pairs of conspecific populations that were both more centrally located within their ranges. Approximately 80% of all pair-wise trait correlations within populations were greater in the north, but these differences were unrelated to the position of the sampled population with respect to the geographic range of the species. Conclusions Neither the degree of morphological integration, nor ranks of P, indicated greater evolutionary constraint at range edges. Characteristics of P observed here provide no support for constraint contributing to the formation of these species’ borders, but may instead reflect structural change in P caused by selection or drift, and their potential to evolve in the future.

  20. The Borders of "Shopluk" and/or Shops without Borders

    2015-08-01

    Full Text Available A historic and cultural region exists at the heart of the Balkans, known in geographic and ethnographic research as Shopluk. This is a region in which, over the last 150 years, state boundaries were moved several times as a result of 5 different wars. Today, the historic Shopluk is where the borders of three nations converge – Republic of Bulgaria, Republic of Serbia and the Republic of Macedonia – and, during the last decade, the region was declared one of the “Euroregions” on the Balkans. Despite the historical similarities in traditional culture and language of this population, in the 19th century it became a subject of nationalist ambitions and a propaganda “wars” between the new national states of Serbia and Bulgaria. The joining of Bulgarian-inhabited parts of Shopluk (the regions of today’s Dimitrovgrad and Bosilegrad in Serbia to the Kingdom of Serbs, Slovenes and Croats in 1919 created a long-lasting tension between the two countries, some residues of which can be felt in everyday relations even today. On the other hand, it has been a century-long tradition for men in this region to take part in seasonal labour migrations all over the Balkan Peninsula, despite political borders. In this way, preserving their cultural and lingual specifics, the groups of seasonal workers – migrants from Shopluk, became a bridge for cultural interaction and exchange with other regions in the neighbour countries. Even though today the population of Shopluk exhibits different national identities, historical similarities in culture and language can turn the Euroregion between Nish, Sofia and Skopje from one of the poorest on the Balkans to one of the most integrated and prosperous.

  5. A polyhedral approach to computing border bases

    CERN Document Server

    Braun, Gábor

    2009-01-01

    Border bases can be considered to be the natural extension of Gr\\"obner bases that have several advantages. Unfortunately, to date the classical border basis algorithm relies on (degree-compatible) term orderings and implicitly on reduced Gr\\"obner bases. We adapt the classical border basis algorithm to allow for calculating border bases for arbitrary degree-compatible order ideals, which is \\emph{independent} from term orderings. Moreover, the algorithm also supports calculating degree-compatible order ideals with \\emph{preference} on contained elements, even though finding a preferred order ideal is NP-hard. Effectively we retain degree-compatibility only to successively extend our computation degree-by-degree. The adaptation is based on our polyhedral characterization: order ideals that support a border basis correspond one-to-one to integral points of the order ideal polytope. This establishes a crucial connection between the ideal and the combinatorial structure of the associated factor spaces.

    2016-04-01

    Full Text Available In this paper I investigate how an international border is 'revitalised' in political discourses as opposed to lived experiences. Based on narratives I have collected from border dwellers on both sides of the current border between Latvia and Rus-sia and placing them into a broader context of current border debates, I analyse how geographical and social mobility is remembered from Soviet times and reworked in current contexts. I argue that while politically the border is revitalised through aban-doning and forgetting the Soviet past and through the idea of constant threats in the future, locally it is revitalised through giving a life to the abandoned: memories of 'vigorous times' in life-courses and material things. People who dwell at the border did not move themselves: the international border moved several times in one cen-tury leaving border dwellers' memories and significant places on the 'other' side. I focus on how these borders were crossed in the past, how they are (not crossed now, and the social meanings assigned to these circumstances. In the current con-text I follow diverse paths of reasoning that describe how the uneven flow of goods and people through the Latvian-Russian border shapes the power dynamic against which the people living in the border area used to reconstruct imaginaries of 'Soviet times' versus 'Europe' and 'vigorous times' versus decline.

    Full Text Available To cooperate means to work and act together for a common advantage or purpose. The cooperation across borders, between different countries and regions sharing the same border, to reach common goals, is aimed to increase the overall competitiveness of the regional economy and to improve the quality of living standards for the these areas. European Union’s programmes are good accelerators for cross-border cooperation. The paper is focused on cross-border cooperation programmes at the external border of the EU and the expected impact of the allocated funds. The cross-border cooperation programmes are creating the conditions to exist the relationships between different social and economic stakeholders in order to contribute to economic and social development by supporting SME development, innovation, human resources development, civil society and local communities, increasing educational, social, cultural and sporting exchanges, improving local governance in different cross-border areas.

  8. Pelletization of fine coals. Final report

    1995-12-31

    Coal is one of the most abundant energy resources in the US with nearly 800 million tons of it being mined annually. Process and environmental demands for low-ash, low-sulfur coals and economic constraints for high productivity are leading the coal industry to use such modern mining methods as longwall mining and such newer coal processing techniques as froth flotation, oil agglomeration, chemical cleaning and synthetic fuel production. All these processes are faced with one common problem area--fine coals. Dealing effectively with these fine coals during handling, storage, transportation, and/or processing continues to be a challenge facing the industry. Agglomeration by the unit operation of pelletization consists of tumbling moist fines in drums or discs. Past experimental work and limited commercial practice have shown that pelletization can alleviate the problems associated with fine coals. However, it was recognized that there exists a serious need for delineating the fundamental principles of fine coal pelletization. Accordingly, a research program has been carried involving four specific topics: (i) experimental investigation of coal pelletization kinetics, (ii) understanding the surface principles of coal pelletization, (iii) modeling of coal pelletization processes, and (iv) simulation of fine coal pelletization circuits. This report summarizes the major findings and provides relevant details of the research effort.

  9. Automatic Intruder Combat System: A way to Smart Border Surveillance

    Full Text Available Security and safeguard of international borders have always been a dominant issue for every nation. A large part of a nation’s budget is provided to its defense system. Besides wars, illegal intrusion in terms of terrorism is a critical matter that causes severe harm to nation’s property. In India’s perspective, border patrolling by Border Security Forces (BSF has already been practiced from a long time for surveillance. The patrolling parties are equipped with high-end surveillance equipments but yet an alternative to the ply of huge manpower and that too in harsh environmental conditions hasn’t been in existence. An automatic mechanism for smart surveillance and combat is proposed in this paper as a solution to the above-discussed problems. Smart surveillance requires automatic intrusion detection in the surveillance video, which is achieved by using optical flow information as motion features for intruder/human in the scene. The use of optical flow in the proposed smart surveillance makes it robust and more accurate. Use of a simple horizontal feature for fence detection makes system simple and faster to work in real-time. System is also designed to respond against the activities of intruders, of which auto combat is one kind of response.

    At the end of the year 2006, France proposed the introduction of a 'climatic tariff' into the discussion of the international climatic protection. The 'climatic tariff' shall adjust extra costs, which result from the domestic production by means of environmental protection instruments and to which the import goods are not exposed, with import/export compensatory payments in the form of import duties and/or taxes on import goods. The introduction of an import/export compensatory payment system aims to load imported goods equivalent to domestic products in order to adjust competitive disadvantages. In the contribution under consideration the authors report on possibilities and problems of design for an import/export tax compensatory. The authors examine the validity of the measures of import/export compensation from legal view the World Trade Organization (Geneva, Switzerland) based on the General Agreement on Tariffs and Trade.

  12. Languaging the Borders of Europe

    Directory of Open Access Journals (Sweden)

    Olivier Kramsch

    2015-11-01

    Full Text Available Emerging from a discomfort with the blind spots encountered within and across theorizations of language and space in the field of human geography, in this article, we argue for “making space” for conceptualizations that speak from and through the everyday territories of migrants in Europe today. Inspired by a range of writers thinking postcolonially and multi/trans-lingually, the authors draw on their own embodied migrant experience to argue for re-envisioning Europe’s borders through multiple languaging practices. “Languaging”, in this view, takes linguistic practices in a migrant context as an inherently prosthetic activity, whereby any dominant, national host language is inevitably subject to the subterranean rumblings of all the languages a migrant brings with her on her global journeys. Conceived as being saturated with prosthetic “absence(s”, migrant languaging practices rework cultural geography’s bounded, inward-looking, and security-fixated understanding of the language/territory nexus, the better to open a vital space for re-envisioning language’s everyday territories as sites for translational solidarity and becoming.

  13. Semantic Borders and Incomplete Understanding.

    Science.gov (United States)

    Silva-Filho, Waldomiro J; Dazzani, Maria Virgínia

    2016-03-01

    In this article, we explore a fundamental issue of Cultural Psychology, that is our "capacity to make meaning", by investigating a thesis from contemporary philosophical semantics, namely, that there is a decisive relationship between language and rationality. Many philosophers think that for a person to be described as a rational agent he must understand the semantic content and meaning of the words he uses to express his intentional mental states, e.g., his beliefs and thoughts. Our argument seeks to investigate the thesis developed by Tyler Burge, according to which our mastery or understanding of the semantic content of the terms which form our beliefs and thoughts is an "incomplete understanding". To do this, we discuss, on the one hand, the general lines of anti-individualism or semantic externalism and, on the other, criticisms of the Burgean notion of incomplete understanding - one radical and the other moderate. We defend our understanding that the content of our beliefs must be described in the light of the limits and natural contingencies of our cognitive capacities and the normative nature of our rationality. At heart, anti-individualism leads us to think about the fact that we are social creatures, living in contingent situations, with important, but limited, cognitive capacities, and that we receive the main, and most important, portion of our knowledge simply from what others tell us. Finally, we conclude that this discussion may contribute to the current debate about the notion of borders.

    Full Text Available “Borders, boundaries and desirable wishes” is the title of the residential workshop offered to a group of young adults (aged 18-25 of the Centro di Salute Mentale (Mental Health Center of the DSM Basaglia of ASL TO2 in Turin. The idea of the workshop, the definition of the objectives and the topics, which are clearly expressed in the title, come from the work of the team dedicated to group psychotherapies, which has been offering group psychodrama sessions to young adults of this age since 2008. In the delicate move to the adult age, these young adults are lost and stuck in static realities where it is not possible to open up to the dimension of desire nor to the transforming encounter with the Other, since they didn’t have the experience of boundaries and lack. These two elements are necessary to acquire the ability to make projects for oneself. During the workshop the following instruments were used: group, psychodrama and art therapy. The group, as a paternal function, ensured the presence of safe boundaries enabling individuals to experiment; psychodrama and art therapy enabled the bodies to experience encounters and transformations, using doing as a metaphor for the movement against the inhibition of doing and as a way to show oneself to the Other and be able to see the Other. 

  15. Which fine-tuning arguments are fine?

    CERN Document Server

    Grinbaum, Alexei

    2009-01-01

    The argument from naturalness is widely employed in contemporary quantum field theory. Essentially a formalized aesthetic criterion, it received a meaning in the debate on the Higgs mechanism, which goes beyond aesthetics. We follow the history of technical definitions of fine tuning at the scale of electroweak symmetry breaking. It is argued that they give rise to a special interpretation of probability, which we call Gedankenfrequency. By extension of its original meaning, the argument from naturalness is used to compare different models beyond the Standard Model. We show that in this case naturalness cannot be defined objectively. Rather, it functions as socio-historical heuristics in particle physics and it contributes to the advent of a probabilistic version of Popper's falsificationism.

    This article reflects on European borders and their everyday dynamics from a cross-border perspective. The article begins with a discussion of recent events that question current border policies in the European Union, reviews the literature on borders and border territories, and finally moves on to a discussion of the everyday effects of cross-border practices on the inhabitants of border spaces. Occasional reference is made to borders in the Americas to complete the picture of this topic. Although the issue of security is indeed relevant, we focus on the economic and social dimensions of cooperation. Three aspects are essential for border residents who attempt to use the advantages of the territories for their global nature: work, shopping, and place of residence. In conclusion, there has been a tendency toward the softening of borders and greater integration of border zones in the European Union.

    Full Text Available Discourse theory is useful for understanding the creation of borders, whether material or imaginary. This paper addresses three situations on Mexico’s southern border between 2000 and 2015 in which elements of discourse theory may be applied. The outcomes were the following: 1 correlations may be made between the elements of the discourse moving from the northern to the southern border, but not in the opposite direction; 2 the process of securitising the discourse about migrants is continuous, and new securitising elements are regularly added; 3 an “elastic borders” phenomenon exists, where borders extend or retract, thereby creating new border regions; and 4 discourses around the southern border are constructed with more pejorative elements than the northern, despite the fact that crime rates are higher in the north.

    In 1997, the Centers for Disease Control and Prevention, the Mexican Secretariat of Health, and border health officials began the development of the Border Infectious Disease Surveillance (BIDS) project, a surveillance system for infectious diseases along the U.S.-Mexico border. During a 3-year period, a binational team implemented an active, sentinel surveillance system for hepatitis and febrile exanthems at 13 clinical sites. The network developed surveillance protocols, trained nine surveillance coordinators, established serologic testing at four Mexican border laboratories, and created agreements for data sharing and notification of selected diseases and outbreaks. BIDS facilitated investigations of dengue fever in Texas-Tamaulipas and measles in California–Baja California. BIDS demonstrates that a binational effort with local, state, and federal participation can create a regional surveillance system that crosses an international border. Reducing administrative, infrastructure, and political barriers to cross-border public health collaboration will enhance the effectiveness of disease prevention projects such as BIDS. PMID:12533288

    In Niger, building more border offices has proven insufficient to tackle the spread of smuggling, drug trade and circulation of jihadists in the Sahel. Instead, everyday petty corruption makes border control ineffective and, while apparently benign, this has severe consequences in contexts...... of volatile security. In this policy brief, Eric Hahonou argues that without complementary activities, the multiplication of border offices could even expand opportunities for corruption. Instead, security policy should focus on creating a culture of effectiveness including systematic and regular staff...... meetings, reporting, law implementation and sanctions as well as new modalities to reward border guards and other state agents. Because corruption is, to a large extent, embedded in the social norms of the users of public service in Niger, sensitisation among transporters, passengers and traders is crucial....

    Full Text Available The main purpose of this practice paper is to describe and analyse the possibilities and complexities of integrated health care across borders. First, we portray an ideal scenario for this type of care with a case of patients suffering from rheumatoid arthritis and living in the Dutch-Belgian frontier area. It shows how cross border care enhances continuity of care/tailor-made care and the other way around. Secondly, based on different literature sources, we describe actual regulations on health care across borders. We show that these regulations can be a major hindrance to integrated care. This raises questions on the scope and content of policies directed at both cross border and integrated care.

    We investigate the impact of borders on the topology of spatially embedded networks. Indeed territorial subdivisions and geographical borders significantly hamper the geographical span of networks thus playing a key role in the formation of network communities. This is especially important in scientific and technological policy making and highlights the interplay of the internationalization pressure toward a global innovation system against the administrative borders imposed by the national and continental institutions. In this study we introduce an outreach index to quantify the impact of borders on the community structure and apply it to the case of the European and US patent co-inventors networks. We find that (a) the US connectivity decays as a power of distance, whereas we observe a faster exponential decay for Europe; (b) European network communities essentially correspond to nations and contiguous regions while US communities span multiple states across the whole country without any characteristic geog...

    Maquiladoras, manufacturing plants that primarily assemble foreign components for reexport, are located in concentrations along the northern frontier of the US/Mexico border. These plants process a wide variety of materials using modern industrial technologies within the context of developing world institutions and infrastructure. Hazardous waste generation by maquiladoras represents a critical environmental management issue because of the spatial concentration of these plants in border municipalities where the infrastructure for waste management is nonexistent or poor. These border municipalities contain rapidly increasing populations, which further stress their waste handling infrastructure capacities while exposing their populations to greater contaminant risks. Limited empirical knowledge exists concerning hazardous waste types and generation rates from maquiladorsas. There is no standard reporting method for waste generation or methodology for estimating generation rates at this time. This paper presents a method that can be used for the rapid assessment of hazardous waste generation. A first approximation of hazardous waste generation is produced for maquiladoras in the three municipalities of Nogales, Sonora, Mexicali, Baja California, and Cd. Juarez, Chihuahua, using the INVENT model developed by the World Bank. In addition, our intent is to evaluate the potential of the INVENT model for adaptation to the US/Mexico border industrial situation. The press of border industrial development, especially with the recent adoption of the NAFTA, make such assessments necessary as a basis for the environmental policy formulation and management needed in the immediate future.

  11. The California Border Health Collaborative: A Strategy for Leading the Border to Better Health

    2015-05-01

    Full Text Available There are hundreds of departments and organizations working on border health issues in the California/Baja California border region trying to protect and improve health without a collaborative structure that integrates jurisdictions and organizations. As a result, there is a need to effectively improve the health in the border region by coordinating these organizations to work together and benefit from each other’s best practices. The newly developed California Border Health Collaborative (CBHC can provide the leadership and collaborative culture to positively improve the health of the border region. This article aims to describe the development process of this collaborative to include key ingredients to success, the roles of mulit-level jurisdictions, and policy implications.This article describes the methods used to develop key aspects of collaborative leadership, strategic alignment and a common vision toward the building of this collective impact approach to border health. In addition, we describe the role of key local County (County of San Diego Live Well San Diego initiative, State, (California Department of Public Health- Office of Binational Border Health, Federal (US-Mexico Border Health Commission’s Leaders across Borders, Academia (e.g., University of California San Diego and San Diego State University and non-profit entities (e.g., Project Concern International, San Ysidro Health Center in forming the BHCC. Evaluating the consortium development process included a literature review of similar processes, a review of internal documents and an analysis of developmental events. To this point the CBHC has built a strong, cohesive collaborative on the U.S. side of the border. It is sharing and leveraging local expertise to address many border health issues. Even more importantly, the BHCC has reached a key stage in which it can effectively engage its Baja California, Mexico counterparts in a manner that will prove extremely powerful

  14. Dispersal of fine sediment in nearshore coastal waters

    Warrick, Jonathan A.

    2013-01-01

    Fine sediment (silt and clay) plays an important role in the physical, ecological, and environmental conditions of coastal systems, yet little is known about the dispersal and fate of fine sediment across coastal margin settings outside of river mouths. Here I provide simple physical scaling and detailed monitoring of a beach nourishment project near Imperial Beach, California, with a high portion of fines (40% silt and clay by weight). These results provide insights into the pathways and residence times of fine sediment transport across a wave-dominated coastal margin. Monitoring of the project used physical, optical, acoustic, and remote sensing techniques to track the fine portion of the nourishment sediment. The initial transport of fine sediment from the beach was influenced strongly by longshore currents of the surf zone that were established in response to the approach angles of the waves. The mean residence time of fine sediment in the surf zone—once it was suspended—was approximately 1 hour, and rapid decreases in surf zone fine sediment concentrations along the beach resulted from mixing and offshore transport in turbid rip heads. For example, during a day with oblique wave directions and surf zone longshore currents of approximately 25 cm/s, the offshore losses of fine sediment in rips resulted in a 95% reduction in alongshore surf zone fine sediment flux within 1 km of the nourishment site. However, because of the direct placement of nourishment sediment on the beach, fine suspended-sediment concentrations in the swash zone remained elevated for several days after nourishment, while fine sediment was winnowed from the beach. Once offshore of the surf zone, fine sediment settled downward in the water column and was observed to transport along and across the inner shelf. Vertically sheared currents influenced the directions and rates of fine sediment transport on the shelf. Sedimentation of fine sediment was greatest on the seafloor directly offshore

  15. Acclimation of fine root respiration to soil warming involves starch deposition in very fine and fine roots: a case study in Fagus sylvatica saplings.

    2016-03-01

    Root activities in terms of respiration and non-structural carbohydrates (NSC) storage and mobilization have been suggested as major physiological roles in fine root lifespan. As more frequent heat waves and drought periods within the next decades are expected, to what extent does thermal acclimation in fine roots represent a mechanism to cope with such upcoming climatic conditions? In this study, the possible changes in very fine (diameter Fagus sylvatica saplings subjected to a simulated long-lasting heat wave event and to co-occurring soil drying. For both very fine and fine roots, soil temperature (ST) resulted inversely correlated with specific root length, respiration rates and SSs concentration, but directly correlated with root mass, root tissue density and starch concentration. In particular, starch concentration increased under 28 °C for successively decreasing under 21 °C ST. These findings showed that thermal acclimation in very fine and fine roots due to 24 days exposure to high ST (∼ 28 °C), induced starch accumulation. Such 'carbon-savings strategy' should bear the maintenance costs associated to the recovery process in case of restored favorable environmental conditions, such as those occurring at the end of a heat wave event. Drought condition seems to affect the fine root vitality much more under moderate than high temperature condition, making the temporary exposure to high ST less threatening to root vitality than expected.

    1999-03-18

    The author demonstrates the Border Trade Facilitation System (BTFS), an agent-based bilingual e-commerce system built to expedite the regulation, control, and execution of commercial trans-border shipments during the delivery phase. The system was built to serve maquila industries at the US/Mexican border. The BTFS uses foundation technology developed here at Sandia Laboratories' Advanced Information Systems Lab (AISL), including a distributed object substrate, a general-purpose agent development framework, dynamically generated agent-human interaction via the World-Wide Web, and a collaborative agent architecture. This technology is also the substrate for the Multi-Agent Simulation Management System (MASMAS) proposed for demonstration at this conference. The BTFS executes authenticated transactions among agents performing open trading over the Internet. With the BTFS in place, one could conduct secure international transactions from any site with an Internet connection and a web browser. The BTFS is currently being evaluated for commercialization.

    2010-01-01

    Background: Dermoscopy is one of the major imaging modalities used in the diagnosis of melanoma and other pigmented skin lesions. Due to the difficulty and subjectivity of human interpretation, computerized analysis of dermoscopy images has become an important research area. One of the most important steps in dermoscopy image analysis is the automated detection of lesion borders. Methods: In this article, we present a systematic overview of the recent border detection methods in the literature paying particular attention to computational issues and evaluation aspects. Conclusion: Common problems with the existing approaches include the acquisition, size, and diagnostic distribution of the test image set, the evaluation of the results, and the inadequate description of the employed methods. Border determination by dermatologists appears to depend upon higher-level knowledge, therefore it is likely that the incorporation of domain knowledge in automated methods will enable them to perform better, especially in ...

    Full Text Available This paper studies the possible impacts of liquefied natural gas (LNG projects on natural gas prices on both sides of the U. S.-Mexico border in California. In that state gas prices are high and demand is expected to grow. Several projects for LNG facilities have been proposed and have to cope with public opinions against them. In Baja California, four LNG projects are under development given the rising demand forecasted for the next years. After a detailed study of the opportunity for LNG projects, we conclude with an analysis of the fundamentals of the current and future price formation in both sides of the U. S.- Mexico border.

    Zhu, Y; Pierson, L S; Hawes, M C

    1997-12-01

    Reporter strains of soil-borne bacteria were used to test the hypothesis that chemicals released by root border cells can influence the expression of bacterial genes required for the establishment of plant-microbe associations. Promoters from genes known to be activated by plant factors included virE, required for Agrobacterium tumefaciens pathogenesis, and common nod genes from Rhizobium leguminosarum bv viciae and Rhizobium meliloti, required for nodulation of pea (Pisum sativum) and alfalfa (Medicago sativum), respectively. Also included was phzB, an autoinducible gene encoding the biosynthesis of antibiotics by Pseudomonas aureofaciens. The virE and nod genes were activated to different degrees, depending on the source of border cells, whereas phzB activity remained unaffected. The homologous interaction between R. leguminosarum bv viciae and its host, pea, was examined in detail. Nod gene induction by border cells was dosage dependent and responsive to environmental signals. The highest levels of gene induction by pea (but not alfalfa) border cells occurred at low temperatures, when little or no bacterial growth was detected. Detached border cells cultured in distilled water exhibited increased nod gene induction (ini) in response to signals from R. leguminosarum bv viciae.

  6. Extracellular Trapping of Soil Contaminants by Root Border Cells: New Insights into Plant Defense

    Directory of Open Access Journals (Sweden)

    Martha C. Hawes

    2016-01-01

    Full Text Available Soil and water pollution by metals and other toxic chemicals is difficult to measure and control, and, as such, presents an ongoing global threat to sustainable agriculture and human health. Efforts to remove contaminants by plant-mediated pathways, or “phytoremediation”, though widely studied, have failed to yield consistent, predictable removal of biological and chemical contaminants. Emerging research has revealed that one major limitation to using plants to clean up the environment is that plants are programmed to protect themselves: Like white blood cells in animals, border cells released from plant root tips carry out an extracellular trapping process to neutralize threats and prevent injury to the host. Variability in border cell trapping has been found to be correlated with variation in sensitivity of roots to aluminum, and removal of border cell results in increased Al uptake into the root tip. Studies now have implicated border cells in responses of diverse plant roots to a range of heavy metals, including arsenic, copper, cadmium, lead, mercury, iron, and zinc. A better understanding of border cell extracellular traps and their role in preventing toxin uptake may facilitate efforts to use plants as a nondestructive approach to neutralize environmental threats.

    2012-08-01

    This paper examines alcohol-related social problems among Mexican Americans living along the U.S.-Mexico border and in non-border areas. Interviews were conducted among Mexican Americans in the border regions of California, Arizona, New Mexico, and Texas (N=1307). Non-border respondents were interviewed primarily in Houston and Los Angeles (N=1288) as part of the Hispanic Americans Baseline Alcohol Survey (HABLAS). Both the border and HABLAS surveys employed multistage cluster sample designs (response rates were 67% and 76%, respectively). In the bivariate analysis, there were no significant differences between border and non-border areas in the proportion of those with one or more social problem. In non-border areas, the prevalence of alcohol problems did not differ significantly by age. However, along the border the prevalence of alcohol problems was significantly different across age groups, with 18 to 29year old men and women having the highest prevalence. The final models showed no residence effect on problem likelihood. Drinking was strongly associated with problems. Although young border residents had higher problem prevalence rates than older residents, the logistic regression models showed no effect of border residence on the likelihood of problems, indicating that problems are due to alcohol consumption, not the border environment. The border, however, did appear to influence more drinking among young people. Regardless of residence, alcohol treatment and preventive interventions tailored to Mexican Americans are essential and special attention should be focused on younger individuals near the border.

  19. The Kalimantan Border Oil Palm Mega-project

    Energy Technology Data Exchange (ETDEWEB)

    Wakker, E. [AIDEnvironment, Amsterdam (Netherlands)

    2006-04-15

    A few years ago, the Indonesian government and sections of the palm oil industry united in the Indonesian Palm Oil Commission (IPOC) to undertake efforts to restore the atrocious public image that the palm oil industry had earned abroad for its role in the demise of Indonesia's tropical rainforests, the massive forest fires and haze in 1997-1998, and for the widespread conflicts between plantation companies and local communities. If IPOC succeeded in restoring the palm oil industry's image abroad, it was shattered again after June 2005 when the Indonesian Minister of Agriculture revealed details of a government plan to develop the world's largest oil palm plantation in a 5-10 kilometer band along the border of Kalimantan and Malaysia. To finance the USD 567 million plantation project, the Indonesian President and Chamber of Commerce and Industry (KADIN) had already met up with the Chinese government and private sector several times, resulting in Memoranda of Understanding between (among other) the Artha Graha and Sinar Mas groups from Indonesia and the Chinese CITIC group and Chinese Development Bank (CDB). The oil palm mega-project, launched in Indonesia under the banner of 'bringing prosperity, security and environmental protection to the Kalimantan border area', turned sour when a business plan developed by the Indonesian State Plantation Corporation (PTPN) began to circulate. This document contained a map that showed beyond doubt how the 1.8 million hectare oil palm project would trash the primary forests of three National Parks, cut through rugged slopes and mountains utterly unsuitable for oil palm cultivation and annihilate the customary rights land of the indigenous Dayak communities in the border area. This report describes what has come of the Kalimantan border oil palm mega-plan since it was announced, who is involved and what research, lobby and campaigning has led to so far. In particular, this study aims to inform civil

    2016-08-09

    A mixture of fine powder including thorium oxide was converted to granulated powder by forming a first-green-body and heat treating the first-green-body at a high temperature to strengthen the first-green-body followed by granulation by crushing or milling the heat-treated first-green-body. The granulated powder was achieved by screening through a combination of sieves to achieve the desired granule size distribution. The granulated powder relies on the thermal bonding to maintain its shape and structure. The granulated powder contains no organic binder and can be stored in a radioactive or other extreme environment. The granulated powder was pressed and sintered to form a dense compact with a higher density and more uniform pore size distribution.

    Full Text Available The Hmong are a transnational ethnic people, because of their dispersal from China into Southeast Asia in the early 19th century and from Southeast Asia to Western countries from 1975 onward. However, even within the context of Southeast Asia and southern China, the Hmong are a transnational ethnic group, due to state boundaries and the enforcement of international laws.Scholars speak as though the Hmong population has crossed political and legal borders by their movement across state boundaries and international borders. However, I argue that it is the political, social, and legal borders that have cut across the Hmong people and subjected them to be citizens of different modern nation-states. Even in the present time, these borders still, and continuously, play important roles that cross and divide the Hmong people into distinctive subgroups and fragments. In this article, I will start by describing the generally understood situation of Hmong being across national borders, and then will explain my argument that borders are across the Hmong.

    2005-01-01

    There is no agreement as to where the limits of consciousness lie, or even if these putative borders exist. Problems inherent to the study of consciousness continue to confound efforts to establish a universally accepted theory of consciousness. Consequently, clinical definitions of consciousness and unconsciousness are unavoidably arbitrary. Recently, a condition of severely altered consciousness has been described, which characterizes the borderzone between the vegetative state and so-called "normal" consciousness. This condition, referred to as the minimally conscious state (MCS), is distinguished from the vegetative state by the presence of minimal but clearly discernible behavioral evidence of self or environmental awareness. This chapter reviews the diagnostic criteria, pathophysiology, prognostic relevance, neurobehavioral assessment procedures and treatment implications associated with MCS.

  11. Imagining and Imaging Borders: Understanding Borderlands for Global Sustainability

    Science.gov (United States)

    Konrad, V.

    2013-11-01

    Borders are increasingly complex human responses and social constructions in a world where globalizing forces confront basic human concerns for security and certainty. In an effort to provide a background to assess research directions for imaging borders, this paper explores what we know about borders, and what we do not know well about borders. Borders in globalization are the meeting points of globalizing forces of security, trade and migration flows with emerging technologies, self determination and regionalization around the world. We need to know more about how: self determination fuels secessions and new borders; borders result from complex rather than simple policy and governance issues; borders depend on the political clout of borderland communities; market and migration flows impact borders; and borders are always in motion. The paper shows how these organizing principles underlie the basic themes of border governance, flows, culture, history, security and sustainability. Finally, the paper offers two brief illustrations of border imaging to link this presentation to the following discussion of the workshop.

  13. The Nature and Functions of European Political Borders

    Directory of Open Access Journals (Sweden)

    Jernej Zupančič

    2008-07-01

    Full Text Available The political border limits a state’s territory and symbolizes the extent of a state’s power and ownership. Borders give integrity to the inner state territory which they enclose (the role of establishing national integrity and at the same time form an outer boundary segregating the state territory from the surrounding politicial entities (the segregation role. European borders are old and reflect the political history of an old continent. The last major border changes happened after World War II. Over the centuries borders were merely lines separating one territory from another. Such borders were understood as »frontiers«. Forming an effective barrier against enemies was the overriding function of borders. Many borders were fortified and further enhanced by means of various defensive systems. In the second half of the 20th century the character of political borders changed. They became a contact area between countries, nations and cultures. Contemporary European borders reflect the colourful history of an old continent. They are predominantely functional markers: they represent the political and juridical delimitation of territories, they mark economic barriers and show their defensive nature and reveal the extent of cultural contact. As a result of European integration processes, the nature of political borders has changed: instead of division, their integration role is brought to the fore. A united Europe is nevertheless still not a borderless Europe! The borders within the »Schengen-area« have retained their political and administrative functions, it is just that the customs and security checks at the borders have been removed. During the period of European integration, borderlines were stabilized in accordance with the 1974 Helsinki Agreement. But despite this we can still observe ongoing changes to state borders, particularly in areas of conflict such as the Balkan peninsula. It seems after all that the process of demarcation

  15. Opportunities for Cross-Border Entrepreneurship Development in a Cluster Model Exemplified by the Polish–Czech Border Region

    Directory of Open Access Journals (Sweden)

    Joanna Kurowska-Pysz

    2016-03-01

    Full Text Available The subject of the paper is the analysis and evaluation of cross-border entrepreneurship development opportunities on the basis of cross-border cooperation, which has gradually evolved from consisting of bilateral partnerships to a networking model or even a cluster. The study conducted at the Polish–Czech border area indicates that, in terms of the development of cross-border cooperation, the economic sphere is lagging far behind social activities such as culture, education and tourism. At the same time, Polish and Czech enterprises are not sufficiently mobilized to develop cross-border entrepreneurship, although a number of support instruments in this regard have been proposed. Sustainable development of the border should take into account both social and economic aspects. An important research problem therefore becomes determining the possibility of boosting the development of cross-border entrepreneurship on the basis of the existing forms of cross-border cooperation, including cooperation in the social sphere. The aim of this paper is to define the conditions and opportunities for the development of cluster cooperation in the area of cross-border entrepreneurship. The author has attempted to resolve whether the intensity of cross-border cooperation can be a factor which mobilizes companies to develop their cross-border entrepreneurship and whether cross-border entrepreneurship can be further developed within the cluster model.

    Eminaga, S; Cherubini, G B; Shelton, G D

    2012-10-01

    A two-year old, male entire Border collie was presented with a one-year history of exercise-induced collapsing on the pelvic limbs. Physical examination revealed generalised muscle atrophy. Neurological examination supported a generalised neuromuscular disorder. Electromyography revealed spontaneous electrical activity in almost all muscles. Unfixed and formaldehyde-fixed biopsy samples were collected from the triceps brachii, longissimus and vastus lateralis muscles. Histopathological, histochemical and ultrastructural examinations of biopsy specimens were consistent with either centronuclear or myotubular myopathy. The dog clinically improved with supportive treatment with L-carnitine, co-enzyme Q10 and vitamin B compound. To the authors' knowledge, this is the first report of centronuclear/myotubular myopathy in a Border collie.

  20. Changing European borders: from separation to interface? An introduction

    Directory of Open Access Journals (Sweden)

    Jen Nelles

    2011-03-01

    Full Text Available The aim of this special issue is to address the evolution of European borders from a comparative perspective. This collection of papers spans a wide variety of topics in the realm of borderland studies. Although each engages with a single empirical or theoretical case collectively they identify nuances relevant to the theoretical elaboration of borders, and particularly contribute to the field of sub-national cross-border cooperation. In the course of its analysis each paper contributes to a broader understanding of the definition of cross-border regions; identifies a set of barriers to cooperation in these contexts; explores the role of identities on cooperation and of the role of borders in constructing those identities; and reflects on the socio-political meanings and uses of these international boundaries. This introduction discusses theoretical significance of these contributions to major debates in the study of borders and border regions.

  1. Dynamic transcriptional signature and cell fate analysis reveals plasticity of individual neural plate border cells

    Roellig, Daniela; Tan-Cabugao, Johanna; Esaian, Sevan; Bronner, Marianne E

    2017-01-01

    The ‘neural plate border’ of vertebrate embryos contains precursors of neural crest and placode cells, both defining vertebrate characteristics. How these lineages segregate from neural and epidermal fates has been a matter of debate. We address this by performing a fine-scale quantitative temporal analysis of transcription factor expression in the neural plate border of chick embryos. The results reveal significant overlap of transcription factors characteristic of multiple lineages in individual border cells from gastrula through neurula stages. Cell fate analysis using a Sox2 (neural) enhancer reveals that cells that are initially Sox2+ cells can contribute not only to neural tube but also to neural crest and epidermis. Moreover, modulating levels of Sox2 or Pax7 alters the apportionment of neural tube versus neural crest fates. Our results resolve a long-standing question and suggest that many individual border cells maintain ability to contribute to multiple ectodermal lineages until or beyond neural tube closure.

    Full Text Available Polish and Russian cross-border cooperation is governed by lawful agreements. The enlargement of the Schengen Area had a significant impact on Kaliningrad Oblast relations and cross-border cooperation with its neighbours. The introduction of visas between Poland and Russia hindered and restricted local border trade which had for years been the only measure mitigating social and economic problems of the cross-border regions. Nevertheless, border traffic between Poland and Kaliningrad grew steadily, to exceed four million in 2012.

    2013-01-01

    Full Text Available This systematic review elaborates the concepts and impacts of border malaria, particularly on the emergence and spread of Plasmodium falciparum and Plasmodium vivax multidrug resistance (MDR malaria on Thailand-Myanmar and Thailand-Cambodia borders. Border malaria encompasses any complex epidemiological settings of forest-related and forest fringe-related malaria, both regularly occurring in certain transmission areas and manifesting a trend of increased incidence in transmission prone areas along these borders, as the result of interconnections of human settlements and movement activities, cross-border population migrations, ecological changes, vector population dynamics, and multidrug resistance. For regional and global perspectives, this review analyzes and synthesizes the rationales pertaining to transmission dynamics and the vulnerabilities of border malaria that constrain surveillance and control of the world’s most MDR falciparum and vivax malaria on these chaotic borders.

    Political borders are controversial and contested spaces. In an attempt to better understand movement along and through political borders, this project applied the metaphor of a membrane to look at how people, ideas, and things ''move'' through a border. More specifically, the research team employed this metaphor in a system dynamics framework to construct a computer model to assess legal and illegal migration on the US-Mexico border. Employing a metaphor can be helpful, as it was in this project, to gain different perspectives on a complex system. In addition to the metaphor, the multidisciplinary team utilized an array of methods to gather data including traditional literature searches, an experts workshop, a focus group, interviews, and culling expertise from the individuals on the research team. Results from the qualitative efforts revealed strong social as well as economic drivers that motivate individuals to cross the border legally. Based on the information gathered, the team concluded that legal migration dynamics were of a scope we did not want to consider hence, available demographic models sufficiently capture migration at the local level. Results from both the quantitative and qualitative data searches were used to modify a 1977 border model to demonstrate the dynamic nature of illegal migration. Model runs reveal that current US-policies based on neo-classic economic theory have proven ineffective in curbing illegal migration, and that proposed enforcement policies are also likely to be ineffective. We suggest, based on model results, that improvement in economic conditions within Mexico may have the biggest impact on illegal migration to the U.S. The modeling also supports the views expressed in the current literature suggesting that demographic and economic changes within Mexico are likely to slow illegal migration by 2060 with no special interventions made by either government.

    Full Text Available Although literature and poetry have numerous borders of their own,these are rarely assumed to have any significance for the world out-side the text itself. A number of reasons for this distinctive division certainly stem from the literary field itself. This paper intends to indicate the exclusivist stance of some theories of literature, and the inclucivist of others, before exploring the possibilities of bridging between borders in text and territory by reference to the life and literature of Oscar Wilde and a performative and imaginative analysis of Paul Muldoon's epigrammatic poem The Plot.

    Foreign-owned industry in the form of assembly plants, termed maquiladora, has become very important in Mexico to the extent that it represents the second largest source of foreign exchange and is a valuable source for employment and regional development. The economic prosperity gained from the rapid growth of the maquiladora industry has been accompanied by increased environmental and human health risks associated with generation of hazardous waste. Diversification of industry has resulted in the predomination of those sectors that likely use hazardous substances. The Mexicali-Calexico border region was selected to demonstrate the potential for environmental and health risks associated with the generation of hazardous waste. Estimates for the generation of hazardous waste were obtained from 34 maquiladora plants in Mexicali, represented by the electronic and electrical equipment and parts, mechanical and transportation equipment, and toys and sporting equipment sectors. Repeated detection of volatile organic compounds in the New River at the US-Mexico border suggests that hazardous waste from the printed circuit board industry in Mexicali is not being disposed of in a proper manner. Potential adverse health effects, such as carcinogenic and mutagenic responses associated with the detected volatiles, are discussed. US and Mexico national legislation and the Binational Environmental Agreement were examined for their adequacy to ensure proper management of hazardous waste generated by the maquiladora industry. Environmental policy options are presented that focus on: (1) increased environmental accountability of US parent companies for their maquiladora assembly plants in Mexico; and (2) more integration between US Customs and border states with the US Environmental Protection Agency to improve the binational management of hazardous waste generated by the maquiladora industry.

This area was formerly a border area between two states that eventually became politically united. Much of the area is uplands, and the seismicity is moderate to low. This makes for some problems in studying historical seismicity, yet the area provides a number of case studies of general interest in the field of historical seismology, including a rare case of being able to track down a «missing» earthquake.

  12. Comparative balance of border regulations in four neighboring Caribbean countries

    Directory of Open Access Journals (Sweden)

    Silvia Cristina Mantilla Valbuena

    2016-07-01

    Full Text Available This article seeks to investigate whether there is a potential for border integration among four adjoining Caribbean countries: Colombia, Nicaragua, Panama and Costa Rica. The discussion is part of the “cross-border” concept and the integration of subnational entities in two or more nation states, with particular emphasis on the role played by the societies that inhabit border regions. A comparative analysis model is used to assess border regulations in each country’s various territorial levels based on relevant legal elements, autonomous processes and decentralization. The article concludes that the more modern each country’s border regulations and constitutional, political and administrative reforms are, the greater the likelihood of cross-border integration. Colombia and Nicaragua have the highest potential for integrating their borders, whereas Panama and Costa Rica have the lowest potential.

  14. Managing US-Mexico "border health": an organizational field approach.

    Science.gov (United States)

    Collins-Dogrul, Julie

    2006-12-01

    During World War II Mexican and US health professionals and organizations constructed a transnational organizational field to manage the border's public health problems. Despite barriers to inter-organizational cooperation, including disparate administrative structures and North-South stratification, the field's transnational approach to health on the border has continued for 60 years. Using archival data to track changes in the number and types of organizations, this article argues that the field practitioners call "border health" reconfigured during the North American Free Trade Association (NAFTA) decade from an era of loosely organized professionals to a specialized bureaucracies era. This change brought new vitality to border health, with transnational ties increasing and diversifying, but has not weakened entrenched cross-border inequalities. The organizational history of the US-Mexico border health field demonstrates how macro-politics and inter-organizational stratification shape transnational public health problems.

    Full Text Available The article will be devoted to such problems as a idea of subsidiarity, a cosmopolitan right and a visitor figure in context and interpretation of ancient and modern philosophy. The article deals with the concept of subsidiarity which is taken as a point of departure for the discipline of borderology, an academic study with Kantian roots. Borderology, according to the principle of subsidiarity, can present as a new field of investigation which invites philosophers and social scientists to replace a “top down” with a “bottom up” procedure. The figure of the visitor is close linked with the experience of subsidiarity which means the freedom and initiative below the level of State. In Immanuel Kant’s strategy for perpetual peace, the figure of the visitor launches a critique of a tendency to self-aggrandizement, characteristic of the modern State and thereby a defense of the political independence of local border regions. The visitor also invites us to see, think and work to liberate our own subjectivity from false voices of sovereignty. Kant articulates the offer of the visitor by bringing in the term Verkehr. Using Kant scholar Otfried Höffe,s methodology we show how idea of subsidiarity is overlooked in international political theory, explain some constitutive principles of borderology, from which is more important is the methodological principle of an intercultural discourse and presents borderology as an anti-Huntingtonian model for border studies.

    Since 2002 a regional seismic network from Jalisco Civil Defense and University of Guadalalajara is monitoring seismicity at the northwest border of Jalisco block. With the installation of a seismic station on Ceboruco Volcano, by Nayarit Civil Defense, coverage of the network extends to east. Ceboruco Volcano is located on the Tepic-Zacoalco graben, the east border of Jalisco block, this allow us to begin to monitoring this area. The zone of Bahia de Banderas, between the north coast of Jalisco and south coast of Nayarit, probably on a tectonic triple point, is a region of high seismic potential. Activ tectonic structures and clusters in the zone of El Tuito and the Dam Cajon de Pe¤as have been identified. The seismicity in the north area of the bay is low, meanwhile in the south, where the bay is deeper, the seismicity level is higher with an East-West tendency. At the east, the Amatlan de Ca¤as-Ameca zone presents continue activity, here have been possible to locate events with local magnitude between 2 and 4. Tectonovolcanic events registred at Ceboruco station presents waveform with scattering. The seismic distribution of the coast of Jalisco shows parallel alignments to the trench throughout al the coast. Other perpendicular alignments to the coastline show active morphologic structures within the Jalisco block related to the subduction of the Rivera plate under the Jalisco block.

    The balancing market integration has been highlighted as a necessary step to reach the European Union goal for the development of an effective, competitive single market for electricity across Europe. In this paper it is described the work done by RTE, REE and REN regarding the design of a non-discriminatory, efficient and reliable multi-TSO Cross Border Balancing Mechanism at regional level, extendible to other control areas. The implementation of this multi-TSO Cross Border Balancing Mechanism will aim at increasing the operational security, enhancing the Liquidity and Competition of balancing markets, facilitating the integration of energy produced by Renewable Energy Sources while optimizing the use of Interconnection capacities. With this mechanism, the three TSOs will be able to exchange to each other balancing energy through the available interconnection capacities after the last intraday market sessions. This mechanism will be based on a common IT platform where TSOs will share their available surplus of reserves and communicate their balancing needs. The available interconnection capacities will be taken into account in an automatic and centralized way. Two main options are investigated regarding the allocation method: on the one hand, the first come first served approach (FCFS), on the other hand, the ''social welfare'' optimization approach.

  3. The Assessment Of Geographical Borders In Economic Research

    Directory of Open Access Journals (Sweden)

    Markowska Małgorzata

    2016-12-01

    Full Text Available The length of common border between two geographical units is frequently used as a basic weight in spatial analysis. The newest methodological propositions such as tests for hierarchical relations (Markowska et. al. 2014; Sokołowski et. al. 2013, regional spatial moving average and new spatial correlation coefficient (Markowska et. al. 2015 are using border lengths. In cited references new methods have been illustrated by analyses for EU NUTS2 regions. It is obvious that borders between regions belonging to different countries have different socio-economic impact than borders between regions lying in the same country. A new simple method for assesment the importance of borders is proposed in the paper. It is based on a chosen macroeconomic variable available at NUTS 2 level (e.g. GDP, infant mortality, Human Development Index. For neighboring regions bigger value is divided by smaller value giving the local importance of the given border. These measures of local border importance can be than average for borders within the same country and for borders for each pair of neighboring countries.

  4. Fine structure of the malpighian tubule in Aedes aegypti

    Energy Technology Data Exchange (ETDEWEB)

    Mathew, G.; Rai, K.S.

    1976-07-01

    The malpighian tubule in Aedes aegypti adults is formed by 2 cell types: the principal cell which forms the great bulk of the tubule, and the stellate cell interspersed singly along the tubule. Both cell types possess ultrastructural features characteristic of cells engaged in ion balance and osmoregulation. These include extensive basal infolding and the differentiation of an apical brush border of microvilli. The central area of the cytoplasm of the principal cell is highly vacuolated while in the stellate cell it is finely granular lacking vacuoles. The microvilli in the principal cells enclose elongated, dense mitochondria whereas the stellate cell microvilli lack mitochondria. Excretory granules of an as yet unknown chemical nature accumulate in the principal cell cytoplasm after a blood meal.

  5. Prevalence of risk factors for HIV infection among Mexican migrants and immigrants: probability survey in the north border of Mexico

    Full Text Available OBJECTIVE: To estimate the prevalence of risk factors for HIV infection among Mexican migrants and immigrants (MMIs in different geographic contexts, including the sending communities in Mexico, the receiving communities in the United States (US, and the Mexican North border region. MATERIAL AND METHODS: We conducted a probability survey among MMIs traveling through key border crossing sites in the Tijuana (Baja California, Mexico-San Diego (California, US border region (N=1 429. RESULTS: The survey revealed substantial rates of reported sexually transmitted infections, needle-sharing and sexual risk practices in all migration contexts. CONCLUSIONS: The estimated levels of HIV risk call for further binational research and preventive interventions in all key geographic contexts of the migration experience to identify and tackle the different personal, environmental, and structural determinants of HIV risk in each of these contexts.

  6. Who’s Who at the Border? A rights-based approach to identifying human trafficking at international borders

    Directory of Open Access Journals (Sweden)

    Marika McAdam

    2013-11-01

    Full Text Available International borders are widely touted as bastions in the fight against trafficking in persons. This article acknowledges the important role border officials play in preventing human trafficking, but calls for expectations to be tempered by deference to the conceptual complexity of cross-border trafficking and the migration processes involved. The fact that many trafficked victims begin their journeys as irregular or smuggled migrants highlights the challenge posed to border officials in identifying trafficked persons among the people they encounter. Indicators of trafficking generally relate to the exploitation phase, leaving border officials with little guidance as to how persons vulnerable to trafficking can be accurately identified before any exploitation has occurred. Ultimately, this paper advocates a pragmatic rights-based approach in designating anti-trafficking functions to border officials. A rights-based approach to border control acknowledges the core work of border officials as being to uphold border integrity, while ensuring that their performance of this role does not jeopardise the rights of those they intercept nor result in missed opportunities for specialists to identify trafficked persons and other vulnerable people among them.

  7. The Fine-Tuning Argument

    CERN Document Server

    Landsman, Klaas

    2015-01-01

    Our laws of nature and our cosmos appear to be delicately fine-tuned for life to emerge, in way that seems hard to attribute to chance. In view of this, some have taken the opportunity to revive the scholastic Argument from Design, whereas others have felt the need to explain this apparent fine-tuning of the clockwork of the Universe by proposing the existence of a `Multiverse'. We analyze this issue from a sober perspective. Having reviewed the literature and having added several observations of our own, we conclude that cosmic fine-tuning supports neither Design nor a Multiverse, since both of these fail at an explanatory level as well as in a more quantitative context of Bayesian confirmation theory (although there might be other reasons to believe in these ideas, to be found in religion and in inflation and/or string theory, respectively). In fact, fine-tuning and Design even seem to be at odds with each other, whereas the inference from fine-tuning to a Multiverse only works if the latter is underwritten...

  8. Tree species richness affecting fine root biomass in European forests

    Finér, Leena; Domisch, Timo; Vesterdal, Lars; Dawud, Seid M.; Raulund-Rasmussen, Karsten

    2016-04-01

    Fine roots are an important factor in the forest carbon cycle, contributing significantly to below-ground biomass and soil carbon storage. Therefore it is essential to understand the role of the forest structure, indicated by tree species diversity in controlling below-ground biomass and managing the carbon pools of forest soils. We studied how tree species richness would affect fine root biomass and its distribution in the soil profile and biomass above- and below-ground allocation patterns of different tree species. Our main hypothesis was that increasing tree species richness would lead to below-ground niche differentiation and more efficient soil exploitation by the roots, resulting in a higher fine root biomass in the soil. We sampled fine roots of trees and understorey vegetation in six European forest types in Finland, Poland, Germany, Romania, Italy and Spain, representing boreal, temperate and Mediterranean forests, established within the FunDivEUROPE project for studying the effects of tree species diversity on forest functioning. After determining fine root biomasses, we identified the percentages of different tree species in the fine root samples using the near infrared reflectance spectroscopy (NIRS) method. Opposite to our hypothesis we did not find any general positive relationship between tree species richness and fine root biomass. A weak positive response found in Italy and Spain seemed to be related to dry environmental conditions during Mediterranean summers. At the Polish site where we could sample deeper soil layers (down to 40 cm), we found more tree fine roots in the deeper layers under species-rich forests, as compared to the monocultures, indicating the ability of trees to explore more resources and to increase soil carbon stocks. Tree species richness did not affect biomass allocation patterns between above- and below-ground parts of the trees.

  9. Enhancing Surveillance for Arboviral Infections in the Arizona Border Region

    Objective To enhance arboviral surveillance and laboratory capacity to establish a surveillance baseline for the emerging threat of Dengue fever in the Arizona-Mexico border region. Introduction West Nile Virus (WNV) and dengue virus (DENV) are both arboviruses which are transmitted to humans by an infected mosquito bite during blood-meal feeding. The clinical presentations of non-neuroinvasive WNV and dengue fever are similar, and symptoms may include acute onset of high fever, headache, myalgia, arthralgia, nausea, vomiting, and often a maculopapular rash. More serious manifestations of these viruses include fatal encephalitis and meningitis in WNV patients and fatal hemorrhagic disease in dengue patients. Over the last decade, WNV has spread rapidly across North America, reaching Arizona in 2004, and has become a significant cause of human illness since that time. Even though dengue has been described as primarily a disease of the tropics and sub-tropical areas, there is a small but significant risk for dengue outbreaks in the continental United States as evidenced by surveillance efforts in Texas that identified local dengue transmission in 2005. In recent years, outbreaks of dengue have occurred in Mexico border states, most notably Sonora in 2010. That same year, Arizona had the highest incidence of WNV cases in the U.S. including number of neuroinvasive disease cases, total cases, and number of deaths per state. The emergence of DENV and WNV as important public health problems maybe have been due to non-effective mosquito control, global demographic changes (urbanization and population growth), increased air travel, and inadequate surveillance. Methods Vector mapping: Mapping techniques will be utilized to visually depict Aedes aegypti populations captured from previous seasonal public health environmental vector trapping programs. Laboratory capacity: Multi-state laboratory training by CDC Dengue Branch was held in October 2012. Surveillance: The WNV cases

    Full Text Available The expansión of the agricultural frontier in the Argentine pampas implied a re-valuation of "bordering" spaces, which were considered "marginal" by capital. This paper aims at interpreting the socio-territorial impact -from both a material and a symbolic level- being caused by the expansión of the productive, business-profile [agricultural and oil] frontier in the center-west of the province of La Pampa. With the interpretative approach provided by qualitative methodologies, we intend to analyze -in a case study- how these frontier expansión processes altered and re-defined the social arena between the years 2000 and 2010, the social construction of the space and the power relations in Chos Malal

  13. Obtaining the borders of urban areas

    CERN Document Server

    Comin, Cesar Henrique; Costa, Luciano da Fontoura

    2015-01-01

    The access to an ever increasing amount of information in the modern world gave rise to the development of many quantitative indicators about urban regions in the globe. Therefore, there is a growing need for a precise definition of how to delimit urban regions, so as to allow proper respective characterization and modeling. Here we present a straightforward methodology to automatically detect urban region borders. The method is based on the density of street crossings around a single seed point associated to the urban area of interest. We exemplify the potential of the methodology by characterizing the geometry and topology of 21 urban regions obtained from 8 distinct countries. The geometry is studied by employing the lacunarity measurement, which is associated to the regularity of holes contained in a pattern. The topology is analyzed by associating the betweenness centrality of the streets with their respective class, such as motorway or residential, obtained from a database.

  14. [Crossing borders. The motivation of extreme sportsmen].

    Science.gov (United States)

    Opaschowski, H W

    2005-08-01

    In his article "Crossing borders -- the motivation of extreme sportsmen" the author gets systematically to the bottom of the question of why extreme sportsmen voluntarily take risks and endanger themselves. Within the scope of a representative sampling 217 extreme sportsmen -- from the fields of mountain biking, trekking and free climbing, canoyning, river rafting and deep sea diving, paragliding, parachuting, bungee jumping and survival training -- give information about their personal motives. What fascinates them? The attraction of risk? The search for sensation? Or the drop out of everyday life? And what comes afterwards? Does in the end the whole life become an extreme sport? Fact is: they live extremely, because they want to move beyond well-trodden paths. To escape the boredom of everyday life they are searching for the kick, the thrill, the no-limit experience. It's about calculated risk between altitude flight and deep sea adventure.

  15. Usability in Public Services and Border Control

    Science.gov (United States)

    Pirelli, Giuliano

    The paper starts with a brief overview of the scale of disability and associated challenges and puts them in the context of the public policy on disability. It then analyses the usability challenges in public services and border control, including the issues of accessibility, safety and communication. These need to be addressed in future policy proposals, to provide the best assistance by new technologies to elderly people and people with disabilities, avoiding creating new barriers due to incorrect or incomplete initial conception. With increasing flux of novel security technology in mass transportation systems, and particularly the use of biometric identification in airports, the challenge of usability is recognized. This paper analyses these issues in the context of users with disability in an idealized process of Simplifying Passenger Travel (SPT).

  16. Globalization and Cross-Border Labor Organizing

    Directory of Open Access Journals (Sweden)

    Ralph Armbruster

    2015-08-01

    Full Text Available The globalization of the world economy has opened up new possibilities for cross-border labor organizing. In fact, several U.S. unions are working together with unions from Mexico, Honduras, Guatemala, the Dominican Republic, Japan, South Korea, and many European nations. For example, over the last several years, UNITE (Union of Needletrades, Industrial, and Textile Employees, the AFL-CIO, and the international garment workers trade secretariat have worked directly with maquiladora workers in Honduras and the Dominican Republic. These efforts led to the formation of several labor unions and the first contracts ever negotiated in the maquiladoras in the Dominican Republic. In addition, labor rights and solidarity organizations, like the Campaign for Labor Rights, Witness for Peace, and the US/Guatemala Labor Education Project (US/GLEP, along with many other groups, have also played key roles in the formation of maquiladora unions in Nicaragua and Guatemala.

  17. POSTMODERN EDUCATION: CRITICAL AND BORDER PEDAGOGIES

    Directory of Open Access Journals (Sweden)

    Mustafa Kurt

    2006-12-01

    Full Text Available This article discusses the influence of postmodernism on education and investigates the main effects ofpostmodern philosophy on social sciences. It is clearly stated in the article that the effects of postmodernism cannotonly be limited to art and logically it should have an effect on education as well. This effect, described as thepostmodern educational approach, emphasizes that the rudiments of popular culture should also be incorporated toeducation and therefore to curricula. Postmodern educational approach also accentuates the significance of allowing‘others’ who have never possessed the opportunity to articulate their standpoints and desires to have a say in their owneducation. The concrete reflections of postmodern educational approach can be perceived in Critical and BorderPedagogies theorized by Henry A. Giroux. Critical pedagogy aspires to educate individuals who do not acceptoccurrences as they are and are critical of the knowledge they construct all through their education. Only by this waythese individuals will be able to discover their own voices, improve their civilian consciousness by taking risks, andacquire the ability of staying alive and functioning within social relations, traditions and experiences. Border pedagogyis as well a product of postmodern philosophy. It defends counter-text as opposed to the official ones offered, presentedand imposed to learners. Counter-consciousness represents the critical analysis of how the present reads the past andhow the past informs the present. This practice of course results in the re-evaluation of memories and traditions.Memories are the stories which were forgotten or ignored with the support of preserved traditions. It is thereforeconcluded in the article that postmodern educational approach is the critical examination towards dismissing the mainnarratives and discourses which manipulate and configure the curriculum of schools. It is the struggle exercisedtowards the recognition

    Sverre Molland

    2013-11-01

    Full Text Available It is with great honour that I introduce the second issue of the Anti-Trafficking Review (ATR. The first issue received an overwhelming response and has placed the journal at the forefront of rigorous analysis and debate relating to human trafficking and human rights. It raised the topic of accountability in anti-trafficking. This issue hopes to further strengthen the ATR’s position as a global, reputable journal on human trafficking. Strengthening the quality of research, analysis, and reflexivity in the trafficking sector is much needed, and I echo Anne Gallagher’s observation as guest editor of the first issue that standards in anti-trafficking research tend to be less rigorous than in other fields of study. My aim as a guest editor is to contribute to addressing this shortfall by bringing together a set of diverse and insightful articles focussing on the nexus of borders and human rights. It is also my hope that this issue will work towards narrowing the divide between practitioners and academics in anti-trafficking. This is reflected in the varied range of contributors. The last few years have witnessed a significant increase in publishing relating to human trafficking worldwide. However, there is limited measured debate and appraisal of this literature within the anti-trafficking sector. For this reason we have decided to include a book review as a way of highlighting recent major publications. The question of borders, migration control, trafficking and human rights raise contested and controversial questions. The editorial team has attempted to include different perspectives, reflected in the debate section in particular. Needless to say, all papers have been subject to double blind peer review.

  19. Cross-border firing and injury patterns

    Directory of Open Access Journals (Sweden)

    Nital Gupta

    2016-01-01

    Full Text Available Introduction: Cross-border firing are increasingly being common in the modern era. The injuries resulting from these low intensity conflicts are a source of anxiety among treating physicians and their respective governments. The provisions are required to minimise the suffering of the victims viz. Mode of injuries, mortality patterns, adequacy of treatment at pre-hospital and tertiary care hospital and provisions to decrease morbidity and mortality for the people living in these areas. Materials and Methods: A retrospective study was conducted in GMCH, Jammu who suffered injuries due to cross border firing in the month of October, 2014. 68 patients were reported in the causality wing. All the patients were referred from level 2 trauma centre. There were 51 males and 17 females out of which 5 were children. The cause of injury, involvement of organ system, cause of mortality and morbidity and loopholes in prehospital management were identified. Results: Sharpnel were the most common cause of injury followed by indirect trauma. The common cause of mortality was abdominal and thoracic injuries. There were 4 deaths at hospital 2 of which were brought dead and 2 died during the course of treatment. There were twenty patients with extremity injuries, fourteen with chest trauma, eleven with abdomen including parineal injuries, three with head injuries, eight with ENT injuries, three with eye injuries and nine with splinters in the back out of which two were in the spinal canal. Conclusion: Prehospital stabilisation, early transport, in-transit resuscitation, immediate surgery if required and implementation of triage model and ATLS protocol has been the key to reduce mortality and morbidity.

  14. Cross-Border Brides: Vietnamese Wives, Chinese Husbands in a Border-Area Fishing Village

    Directory of Open Access Journals (Sweden)

    Nguyễn Thị Phương Châm

    2014-06-01

    Full Text Available This article traces the lives of a group of Vietnamese women driven by poverty and loss of marriageability to cross the border into China to marry men from the fishing village of Wanwei. Wanwei’s location, only 25 kilometers from the border with Vietnam, enables these women to make fairly regular trips back to their native villages to visit their birth families. Yet, despite the fact that they now live in a designated Jing (ethnic Vietnamese village, where a significant proportion of the population shares their ethnicity, their illegal residential status and recent arrival excludes them from the community of villagers who claim descent from Vietnamese immigrants in the sixteenth century. Despite the hardships these women face as a result of continuing poverty, lack of emotional intimacy in their marriages, and marginal social status, few see themselves as victims of human trafficking. Instead, most take pride in their agency and achievements.

In analogy to the atmospheric phenomena known as parhelic circle, sun dogs, and sun pillars, we have named the features of the patterns observed as parlaseric circle, laser dogs, and laser pillars. The triangular symmetry of the Plateau borders is analogous to the hexagonal symmetry of ice crystals which produce these atmospheric phenomena. Working with one Plateau border at a time, we have observed wave optics phenomena that are not perceived in the atmospheric phenomena, such as diffraction and interference. - Highlights: • We obtained halo formation from light scattering in a Plateau border using an experiment. • We explained halo formation using geometrical theory of diffraction. • An optical element based on a Plateau border is proposed. • We compared some aspects of the parhelic circle with the parlaseric circle.

    The sister-city area of Nogales, Arizona, and Nogales, Sonora, Mexico, is known collectively as Ambos (both) Nogales. This area was historically one city and was administratively divided by the Gadsden Purchase in 1853. These arid-lands have limited and sensitive natural resources. Environmental planning can support sustainable development to accommodate the predicted influx of population. The objective of this research is to quantify the amount of predicted urban growth for the Ambos Nogales watershed to support future planning for sustainable development. Two modeling regimes are explored. Our goal is to identify possible growth patterns associated with the twin-city area as a whole and with the two cities modeled as separate entities. We analyzed the cross-border watershed using regression analysis from satellite images from 1975, 1983, 1996, and 2002 and created urban area classifications. We used these classifications as input to the urban growth model, SLEUTH, to simulate likely patterns of development and define projected conversion probabilities. Model results indicate that the two cities are undergoing very different patterns of change and identify locations of expected growth based on historical development. Growth in Nogales, Arizona is stagnant while the urban area in Nogales, Sonora is exploding. This paper demonstrates an application that portrays how future binational urban growth could develop and affect the environment. This research also provides locations of potential growth for use in city planning.

    The production of nitrocellulose (NC) creates large quantities of waste NC fines in wash water streams. Current processing techniques attempt to remove these fines by cross-flow microfiltration, pressure flotation, settling, centrifugation, and lime precipitation. Pressure flotation, or dissolved air flotation (DAF), is a solid/liquid separation process first developed in the ore processing industry. DAF has since found many applications in the environmental engineering field including: drinking water clarification, sludge thickening, and the clarification of wastewater from a variety of industrial and municipal processes. The work presented herein is part of a larger effort to explore techniques to recover and reuse nitrocellulose (NC) fines resulting from propellant manufacturing processes. Previous papers investigated NC particle stability and interfacial thermodynamics and developed a flotation trajectory model. This paper builds on that work and presents a sensitivity analysis of the flotation trajectory model. The sensitivity analysis explores both operational and parameter estimation uncertainty.

    s challenging environmental issues. The results also brought focus to the potential contributions that DOE’s science and technology could make for solving the many difficult, multi-generational problems faced by hundreds of bi-national communities along the 2,000-mile shared border of the United States and Mexico. Efforts to address these U.S.-Mexico border issues were initially sponsored by the DOE’s Albuquerque and Carlsbad offices. In subsequent years, the U.S. Congress directed appropriations to DOE’s Carlsbad office to address public health, safety and security issues prevalent within U.S.-Mexico border communities. With ASL’s assistance, DOE’s Albuquerque office developed contacts and formed partnerships with interested U.S and Mexican government, academic, and commercial organizations. Border industries, industrial effluents, and public health conditions were evaluated and documented. Relevant technologies were then matched to environmental problem sets along the border. Several technologies that were identified and subsequently supported by this effort are now operational in a number of U.S.-Mexico border communities, several communities within Mexico’s interior states, and in other parts of Latin America. As a result, some serious public health threats within these communities caused by exposure to toxic airborne pollutants have been reduced. During this time, DOE’s Carlsbad office hosted a bilateral conference to establish a cross-border consensus on what should be done on the basis of these earlier investigative efforts. Participating border region stakeholders set an agenda for technical collaborations. This agenda was supported by several Members of Congress who provided appropriations and directed DOE’s Carlsbad office to initiate technology demonstration projects. During the following two years, more than 12 private-sector and DOE-sponsored technologies were demonstrated in partnership with numerous border community stakeholders. All technologies

  9. Fine-grained sediment dispersal along the California coast

    Warrick, Jonathan A.; Storlazzi, Curt D.

    2013-01-01

    Fine-grained sediment (silt and clay) enters coastal waters from rivers, eroding coastal bluffs, resuspension of seabed sediment, and human activities such as dredging and beach nourishment. The amount of sediment in coastal waters is an important factor in ocean ecosystem health, but little information exists on both the natural and human-driven magnitudes of fine-grained sediment delivery to the coastal zone, its residence time there, and its transport out of the system—information upon which to base environmental assessments. To help fill these information gaps, the U.S. Geological Survey has partnered with Federal, State, and local agencies to monitor fine-grained sediment dispersal patterns and fate in the coastal regions of California. Results of these studies suggest that the waves and currents of many of the nearshore coastal settings of California are adequately energetic to transport fine-grained sediment quickly through coastal systems. These findings will help with the management and regulation of fine-grained sediment along the U.S. west coast.

  10. Identifying and characterizing transboundary aquifers along the Mexico-US border: An initial assessment

    Sanchez, Rosario; Lopez, Victoria; Eckstein, Gabriel

    2016-04-01

    The transboundary nature of water dividing Mexico and the United States (U.S.) transforms the entire border region into an instrument of cooperation, a source of conflict, a national security issue, and an environmental concern. Reasonable data collection and research analysis have been conducted for surface waters by joint governmental institutions and non-governmental bodies. However, with the exception of the U.S. Transboundary Assessment Act Program (TAAP) (focusing on the Hueco Bolson, Mesilla Bolson, San Pedro and Santa Cruz aquifers), there is no comparable research, institutional development, or assessment of transboundary groundwater issues on the frontier. Moreover, data collection and methodologies vary between the two countries, there is no broadly accepted definition of the transboundary nature of an aquifer, and available legal and policy frameworks are constrained by non-hydrological considerations. Hence, there is a conceptual and institutional void regarding transboundary groundwater resources between Mexico and the U.S. The purpose of this paper is to bridge this void and characterize transboundary aquifers on the Mexico-US border. It reviews existing international frameworks for identifying hydrological and social criteria that characterize an aquifer as transboundary. It then assesses data from both countries to propose where and which aquifers could be considered transboundary. Finally, the paper proposes an agenda for assessing Mexico-US transboundary aquifers as a means for improving groundwater management in the border region.

  11. Rates and predictors of DUI among U.S.-Mexico border and non-border Mexican Americans.

    2013-10-01

    This paper examines driving under the influence (DUI) arrests and other related factors among Mexican Americans living in U.S.-Mexico border and non-border areas. Respondents in the non-border areas (primarily Houston and Los Angeles) constitute a multistage probability sample (N=1288) of these areas, interviewed as part of the 2006 Hispanic Americans Baseline Alcohol Survey (HABLAS). Respondents in the border area (N=1307) were interviewed between March 2009 and July 2010 and constitute a household probability sample of Mexican Americans living on the border. In both surveys, data were collected during computer assisted interviews conducted in respondents' homes. The HABLAS and the border sample response rates were 76% and 67%, respectively. Border or non-border residential location was not associated with self-reported DUI, 12 month DUI arrest, or lifetime DUI arrest. An increase in consumption of 5 drinks per week was associated with an 18% increase in the chance of self-reporting DUI and an 18% increase in the probability of a lifetime DUI arrest. Binge drinkers were more likely to self-report a DUI event (OR=2.85, 95% CI=1.61-5.03; pDUI arrest (OR=2.81; 95% CI=1.43-5.53, pDUI as a major problem affecting Hispanics. However, while most correctly identified the legal blood alcohol content to drive in their state as .08 g/dl or lower, approximately one third of individuals were unaware of the legal limit. Compared to their non-border counterparts, border men were more likely to identify a bar/tavern/club and border women were more likely to identify a friend or relative's home as the places of last drink before the most recent DUI trip originated. In conclusion, border and non-border Mexican Americans are not different regarding DUI rates. These rates are high in both groups, especially among men. Intervention strategies to decrease DUI should be implemented not only in drinking establishments but also with families.

  12. Woolfian border poetics and contemporary circadian novels

    Directory of Open Access Journals (Sweden)

    Anka Ryall

    2014-07-01

    Full Text Available Virginia Woolf’s circadian novel Mrs Dalloway (1925 has inspired many successors, some of them important works in their own right. Although few of these novels are as explicitly linked to Mrs Dalloway as Michael Cunningham’s The Hours (1998, more recent novels such as Ian McEwan’s Saturday (2005 and Gail Jones’ Five Bells (2011 clearly pay homage to Woolf’s use of the one-day format to reveal whole lives and show how those individual private lives are entangled in history. The essay highlights one particular aspect of these three works, their imaginative and often transformative reworking of elements of Woolfian border poetics, particularly the predominance in Mrs Dalloway of boundary tropes – windows, doors, thresholds – that create a sense of synchronicity between present and past. Adapting Woolf’s boundary tropes to representations of contemporary realities, all three novels in different ways suggest how the present is deepened ”when backed by the past”, as Woolf puts it her memoirs; that is, when the present is not only informed by a remembered past but experienced in terms of both re-enactment and renewal, continuity and change.

    . For contemporary states the planes have become increasingly disaggregated, in the sense that they do not fall into place at one and the same border. Thus, states have to pick and choose different articulations (often inconsistently) on different planes. We illustrate these ideas with instances, present......-day and historical, of bordering. A corollary of there being more need to pick and choose is that articulations of sovereignty change. So, sovereignty is increasingly the material of ‘sovereignty games’, where sovereignty is used as a political instrument. In sum, our theory directs attention to state bordering...

    IN the late 1990s, the Sino-Russian border in northeastern China which had been so silent for many years got busy in a hurry. In the border city of Suifenhe, with a population of only 40,000, and in Dongning County, with its population of 220,000, trains and vehicles drive by on the rails and the road day and night. The annual volume of goods crossing the border amounts to more than 6.5 million tons and the annual number of passengers passing through exceeds 2 million persons. Suifenhe and Dongning now rank first

    The compressive mechanical response of fine sand is experimentally investigated. The strain rate, initial density, stress state, and moisture level are systematically varied. A Kolsky bar was modified to obtain uniaxial and triaxial compressive response at high strain rates. A controlled loading pulse allows the specimen to acquire stress equilibrium and constant strain-rates. The results show that the compressive response of the fine sand is not sensitive to strain rate under the loading conditions in this study, but significantly dependent on the moisture content, initial density and lateral confinement. Partially saturated sand is more compliant than dry sand. Similar trends were reported in the quasi-static regime for experiments conducted at comparable specimen conditions. The sand becomes stiffer as initial density and/or confinement pressure increases. The sand particle size become smaller after hydrostatic pressure and further smaller after dynamic axial loading.

  16. Petrology of the Upper Border Series of the Skaergaard Intrusion

    2009-12-01

    The Upper Border Series crystallized downwards from the roof of the Skaergaard magma chamber. It met with the Layered Series that crystallized upwards from the floor in the Sandwich Horizon that contains the last and most evolved rocks of the intrusion. Previous investigations of the Upper Border Series (Naslund, 1984) have shown that the compositional trends of plagioclase, olivine and pyroxene largely mirror those of the Layered Series. At the same time it was argued that the crystallization sequence in Upper Border Series differed from the Layered Series in that apatite precipitated before magnetite that, in turn, appeared before Ca-rich pyroxene. From the existing data the magma from which the Upper Border Series crystallized was inferred to be enriched in SiO2, K2O, P2O5 and H2O relative to the magma in the lower parts of the intrusion. This has lead to the conception that the Upper Border Series crystallized from a chemically different magma. Here we present new petrography, mineralogy and bulk compositions for samples collected in three profiles through the Upper Border Series (Kilen, Hammerpas and Brødretoppen transects). Although euhedral apatite is present throughout most of the Upper Border Series, we interpret a marked increase in modal apatite late in the crystallization sequence as marking its first appearance on the liquidus at the crystallization front. The plagioclase An% at this level in the Upper Border Series is ˜40 and is identical with plagioclase An% at the level of apatite-in in the Layered Series. Similarly, we find that the plagioclase An% at the onset of FeTi-oxide and sulphide precipitation in the Upper Border Series (52 and 47, respectively) and Layered Series are alike. Finally, we interpret abundant augite in Upper Border Series rocks before magnetite-in as a cumulus phase. We therefore conclude that the crystallization sequences of the two series are identical. The new bulk rock data reveal that the Upper Border Series and the

  19. Signaling pathways and tissue interactions in neural plate border formation.

    Science.gov (United States)

    Schille, Carolin; Schambony, Alexandra

    2017-01-01

    The neural crest is a transient cell population that gives rise to various cell types of multiple tissues and organs in the vertebrate embryo. Neural crest cells arise from the neural plate border, a region localized at the lateral borders of the prospective neural plate. Temporally and spatially coordinated interaction with the adjacent tissues, the non-neural ectoderm, the neural plate and the prospective dorsolateral mesoderm, is required for neural plate border specification. Signaling molecules, namely BMP, Wnt and FGF ligands and corresponding antagonists are derived from these tissues and interact to induce the expression of neural plate border specific genes. The present mini-review focuses on the current understanding of how the NPB territory is formed and accentuates the need for coordinated interaction of BMP and Wnt signaling pathways and precise tissue communication that are required for the definition of the prospective NC in the competent ectoderm.

    In this paper the notion of border will be examined in a cultural life course perspective. I will investigate borders as psycho-cultural constructions created to enable and control meaning-making in the intersection between subjects engagements and concerns and collectively constructed and guiding meanings. An empirical analysis of one boy's life course in and between home, school and a Leisure Time Activity Center in the years 1st to 3rd grade demonstrates a systemic construction of borders involving him, his teachers and his parents and renders the boy to choose between becoming an engaged pupil or a dedicated son. As such, the analysis can illuminate processes of school - home interactions that work opposite of what is intended and become detrimental to children's life. In a cultural life course perspective borders show how life is maintained as meaningful and not only guide the present living but also serve as directional guides into the future.

  1. Measuring cross-border regional integration with composite indicators

    Earlier quantitative studies on cross-border regional integration processes have commonly neglected science, technology and innovation (STI) indicators: even the most notable example of a composite indicator approach to measuring cross-border regional integration, i.e. the Oresund index, lacks...... a sub-category for STI. Consequently, by ignoring cross-border innovation and knowledge flows, the Oresund integration index fails to take into account one of the most important drivers of economic growth in cross-border regions. Therefore, a new composite STI indicator (sub-category) was introduced...... to strengthen the Oresund integration index. This was compiled from patent, publication and collaborative R&D project data. The findings show that this index performs reasonably well in depicting STI integration, while at the same time remaining simple and straightforward enough to be adopted in other cross...

  2. Definig the US-Mexico border as hyperreality

    Directory of Open Access Journals (Sweden)

    Carlos A. Duarte-Herrera

    2002-07-01

    Full Text Available The US-Mexico border has been defined as a periphery, as a transborder social system, and more currently, as a station in transnational circuits. The two first definitions presuppose the strongly criticized concepts of region and cultural area. The third definition shares, along with the other two definitions, the positivist epistemological supposition that the border is a specific entity that can be known and experienced as such by any observer, no matter their social site. This paper is to support the definition of the border as a hyperreality constituted by speeches, practices, and experiences of the different social actors. From this posture, the image of the border as a formal geopolitical division is interpreted as a sustained image and reproduced by government agencies. Likewise, this writing is to support the documentation and promotion of alternative images constructed and reproduced by social actors from different power sites.

  3. Border Detection of Common Carotid Artery Using Hough Transform

    Koya, Yoshiharu; Nagahara, Yoshihiro

    The arteriosclerosis is on the increase with an aging or change of our living environment. For that reason, diagnosis of the common carotid artery using echocardiogram is doing to take precautions carebropathy. The arteriosclerosis of the common carotid artery is diagnosed using Intima-Media Thickness (IMT) which is obtained from echocardiogram. In order to measure IMT from echocardiogram, it is required to detect a border which is a boundary between vessel tissue layers. The method of border detection requires reproducibility and high accuracy. The conventional methods to detect the border curve depend on differential value of brightness on the common carotid artery. Therefore, we can't extract a good candidate point by influence of a noise. In this paper, we propose the high-accuracy detection method by Hough Transform. About high-accuracy, it realized by attaching importance to high reliable candidate point of border.

    2010-01-01

    Geographic borders are not only essential for the effective functioning of government, the distribution of administrative responsibilities and the allocation of public resources, they also influence the interregional flow of information, cross-border trade operations, the diffusion of innovation and technology, and the spatial spread of infectious diseases. However, as growing interactions and mobility across long distances, cultural, and political borders continue to amplify the small world effect and effectively decrease the relative importance of local interactions, it is difficult to assess the location and structure of effective borders that may play the most significant role in mobility-driven processes. The paradigm of spatially coherent communities may no longer be a plausible one, and it is unclear what structures emerge from the interplay of interactions and activities across spatial scales. Here we analyse a multi-scale proxy network for human mobility that incorporates travel across a few to a few...

In this analysis health is understood not only as the absence of illness, but also as knowledge, as a right, and as the pursuit of identity and self-transformation. Similarly, borders here are used as both physical and mental constructs. The special issue represent a multidisciplinary effort that looks at health from a social science perspective through historical, socio-economic, and cultural approaches. It is also concerned with the health inequities across and within national borders, due to economic imperatives, changing technologies and environments. The articles in this special issue explore lessons learned and new ways of understanding health across time and borders, with specific reference to the cases of India, Australia, Hong Kong and China, Pakistan, and Thailand.

  7. Shaping the Victim: Borders, security, and human trafficking in Albania

    Directory of Open Access Journals (Sweden)

    James Campbell

    2013-11-01

    Full Text Available Borders are productive sites where knowledge is gathered and migrant populations are formed. The knowledge gathered from victims of trafficking reinforces a victim narrative that represents a perceived threat to society by highlighting violence, criminality, coercion, and naivety. Using Albania as a case in point, the article looks at trafficked people and the narratives of victimhood that surround them. In the case of trafficked people, the border projected out towards other states produces a discursively defined victim of trafficking. When projected back within the national territory, the border essentially produces a criminalised sex worker. To argue this point, the article discusses the role victims of trafficking play in the EU and looks at how international norms espoused by the OSCE and IOM have prepped the Albanian border for EU ascension and created the means for governable populations within Albania.

  15. Cross-border ties and Arab American mental health.

    Science.gov (United States)

    Samari, Goleen

    2016-04-01

    Due to increasing discrimination and marginalization, Arab Americans are at a greater risk for mental health disorders. Social networks that include ties to the country of origin could help promote mental well-being in the face of discrimination. The role of countries of origin in immigrant mental health receives little attention compared to adjustment in destination contexts. This study addresses this gap by analyzing the relationship between nativity, cross-border ties, and psychological distress and happiness for Arab Americans living in the greater Detroit Metropolitan Area (N = 896). I expect that first generation Arab Americans will have more psychological distress compared to one and half, second, and third generations, and Arab Americans with more cross-border ties will have less psychological distress and more happiness. Data come from the 2003 Detroit Arab American Study, which includes measures of nativity, cross-border ties--attitudes, social ties, media consumption, and community organizations, and the Kessler-10 scale of psychological distress and self-reported happiness. Ordered logistic regression analyses suggest that psychological distress and happiness do not vary much by nativity alone. However, cross-border ties have both adverse and protective effects on psychological distress and happiness. For all generations of Arab Americans, cross-border attitudes and social ties are associated with greater odds of psychological distress and for first generation Arab Americans, media consumption is associated with greater odds of unhappiness. In contrast, for all generations, involvement in cross-border community organizations is associated with less psychological distress and for the third generation, positive cross-border attitudes are associated with higher odds of happiness. These findings show the complex relationship between cross-border ties and psychological distress and happiness for different generations of Arab Americans.

  2. Alternate Pacing of Border-Collision Period-Doubling Bifurcations.

    Science.gov (United States)

    2007-11-01

    Unlike classical bifurcations, border-collision bifurcations occur when, for example, a fixed point of a continuous, piecewise C1 map crosses a boundary in state space. Although classical bifurcations have been much studied, border-collision bifurcations are not well understood. This paper considers a particular class of border-collision bifurcations, i.e., border-collision period-doubling bifurcations. We apply a subharmonic perturbation to the bifurcation parameter, which is also known as alternate pacing, and we investigate the response under such pacing near the original bifurcation point. The resulting behavior is characterized quantitatively by a gain, which is the ratio of the response amplitude to the applied perturbation amplitude. The gain in a border-collision period-doubling bifurcation has a qualitatively different dependence on parameters from that of a classical period-doubling bifurcation. Perhaps surprisingly, the differences are more readily apparent if the gain is plotted vs. the perturbation amplitude (with the bifurcation parameter fixed) than if plotted vs. the bifurcation parameter (with the perturbation amplitude fixed). When this observation is exploited, the gain under alternate pacing provides a useful experimental tool to identify a border-collision period-doubling bifurcation.

    Fine root dynamics (diameter < 1 mm) in mature Fagus sylvatica, with the canopies exposed to ambient or twice-ambient ozone concentrations, were investigated throughout 2004. The focus was on the seasonal timing and extent of fine root dynamics (growth, mortality) in relation to the soil environment (water content, temperature). Under ambient ozone concentrations, a significant relationship was found between fine root turnover and soil environmental changes indicating accelerated fine root turnover under favourable soil conditions. In contrast, under elevated ozone, this relationship vanished as the result of an altered temporal pattern of fine root growth. Fine root survival and turnover rate did not differ significantly between the different ozone regimes, although a delay in current-year fine root shedding was found under the elevated ozone concentrations. The data indicate that increasing tropospheric ozone levels can alter the timing of fine root turnover in mature F. sylvatica but do not affect the turnover rate. - Doubling of ozone concentrations in mature European beech affected the seasonal timing of fine root turnover rather than the turnover rate.

    This study assessed the management of the organic household waste in the Danish-German border region and points out major differences between the systems and their potential effects on the environment using life cycle assessment (LCA). The treatment of organic waste from households in the Danish-German border region is very different on each side of the border; the Danish region only uses incineration for the treatment of organic household waste while the German region includes combined biogas production and composting, mechanical and biological treatment (MBT) and incineration. Data on all parts of the organic waste treatment was collected including waste composition data and data from treatment facilities and their respective energy systems. Based on that the organic waste management systems in the border region were modelled using the EASETECH waste management LCA-model. The main output is a life cycle assessment showing large differences in the environmental performance of the two different regions with the Danish region performing better in 10 out of 14 impact categories. Furthermore, the importance of the substituted district heating systems was investigated showing an impact up to 34% of the entire system for one impact category and showing large difference between each heating system substituted, e.g. in "Global Warming" the impact was from -16 to -1.1 milli person equivalent/tonne treated waste from substitution of centralised hard coal and decentralised natural gas, respectively.

    The composition of the atmosphere over the US-Mexico border region is affected by cross-border transport of emissions in both directions. Air quality issues in the California-Mexico (Cal-Mex) border are associated with air masses originating in the portion of the border region adjacent to California, which includes two of the sister city pairs (Tijuana-San Diego and Mexicali-Calexico) that have the most severe air pollution problems, posing a serious health threat to their inhabitants as well as affecting ecosystem viability and regional climate for large downwind distances. During May-June 2010, an intensive field study was undertaken by US-Mexico collaborative teams to characterize the major sources of primary and secondary particulate matter and precursor gases in the California-Mexico (Cal-Mex) border region, their transport and transformation, and the impact of these emissions on regional air quality and climate. The ground-based measurements included a central fixed site located in Tijuana that housed state-of-the-science instruments to measure gases, aerosols, radiation and meteorological parameters; a mobile eddy covariance laboratory that measured surface-atmosphere exchange fluxes of carbon dioxide, nitrogen oxides, and particle number; several mobile units for criteria pollutants and meteorological parameters; and measurements of fine particles and trace gases at the border crossing areas. Preliminary results from the field study will be presented.

  9. Being thought from beyond our borders: Towards ethical global citizenship

    Johann-Albrecht Meylahn

    2009-09-01

    Full Text Available This article is a response to the challenge of global citizenship in an age of global crisis. Citizenship has to do with where one feels �at home�, namely the space that gifts identity and life. What kind of narrative is necessary to transform global space into a home from where we can go beyond our borders to embrace the other in multidisciplinary research or interfaith praxis? The different models for multidisciplinary research are made possible by the idea that research seeks that which is beyond its borders. This search could be a common space where the different traditions can accommodate one another, but it is not a home. The dominant discourse of this common space is to seek commonality and identities across borders while being aware of but ignoring differences � identity at the expense of differences. A home founded on identity at the expense of difference will always exclude. Theology can either be interpreted as thinking beyond the borders toward the Divine, or the Divine thinking us. The Exodus, the Incarnation and the Cross are all narratives of the Other crossing borders, liberating from boundaries, deconstructing the laws and norms that exclude. The religious traditions of these sacred narratives have something to offer, namely: to be thought by the Other, to receive life and (alien identity from the Other, the gift of a home which is continuously deconstructed by the home still to come, therefore always open for the Other.

    Full Text Available This article analyses the role that the regions have played during this past half century, and which they continue to play now, in the changes that are occurring along the borders between European states and in the webs of interests that are woven as a consequence ofthis evolution. The mapping of borderlines associated with people endowed with singularities is a delicate, complex task, as demonstrated by several paradigmatic examples: the creation of new borders (Flanders and the profound modification of historical orders (the canton of Jura. The difficulty may lie in approval processes and in the appropriate conjugation of interests of other peoples and minorities existing within them. There are several Europeaninstitutions which are contributing to deeply modifying the imaginary of international borders. On the one hand, the Council of Europe, which fosters, among other things, cross-border cooperation and inter-regional cooperation. Secondly, the European Union institutions havetaken many ideas from the Council of Europe and made them their own: the Committee of the Regions and cross-border cooperation. In addition, these institutions force the unitary states to establish a territorial division taking into account the income levels of the population.

    Full Text Available IntroductionThe diabetes hospitalization rate for the region along the U.S. side of the U.S.–Mexico border is unknown, a situation that could limit the success of the Healthy Border 2010 program. To remedy this problem, we analyzed and compared hospital discharge data for Arizona, California, and Texas for the year 2000 and calculated the diabetes hospitalization rates.MethodsWe obtained hospital-discharge public-use data files from the health departments of three U.S. border states and looked for cases of diabetes. Only when diabetes was listed as the first diagnosis on the discharge record was it considered a case of diabetes for our study. Patients with cases of diabetes were classified as border county (BC or nonborder county (NBC residents. Comparisons between age-adjusted diabetes discharge rates were made using the z test.ResultsOverall, 1.2% (86,198 of the discharge records had diabetes listed as the primary diagnosis. BC residents had a significantly higher age-adjusted diabetes discharge rate than NBC residents. BC males had higher diabetes discharge rates than BC females or NBC males. In both the BCs and the NBCs, Hispanics had higher age-adjusted diabetes discharge rates than non-Hispanics.ConclusionThe results of this study provide a benchmark against which the effectiveness of the Healthy Border 2010 program can be measured.

    Ion-mediated changes in xylem hydraulic resistance are hypothesized to result from hydrogel like properties of pectins located in the bordered pit membranes separating adjacent xylem vessels. Although the kinetics of the ion-mediated changes in hydraulic resistance are consistent with the swelling/deswelling behavior of pectins, there is no direct evidence of this activity. In this report we use atomic force microscopy (AFM) to investigate structural changes in bordered pit membranes associated with changes in the ionic concentration of the surrounding solution. When submerged in de-ionized water, AFM revealed bordered pit membranes as relatively smooth, soft, and lacking any sharp edges surface, in contrast to pictures from scanning electron microscope (SEM) or AFM performed on air-dry material. Exposure of the bordered pit membranes to 50 mM KCl solution resulted in significant changes in both surface physical properties and elevation features. Specifically, bordered pit membranes became harder and the fiber edges were clearly visible. In addition, the membrane contracted and appeared much rougher due to exposed microfibers. In neither solution was there any evidence of discrete pores through the membrane whose dimensions were altered in response to the ionic composition of the surrounding solution. Instead the variable hydraulic resistance appears to involve changes in the both the permeability and the thickness of the pit membrane.

    Full Text Available Xylem hydraulic resistance varies with ion concentration in sap solution. It is assumed that this variation in resistance results from hydrogel like properties of pectins located in bordered pit membranes separating adjacent vessels. Although kinetics of the resistance change suggests swelling/deswelling behavior of the pectins, there is no direct evidence of this activity. In this report we provide evidence of structural changes in bordered pit membranes responding to variation in ionic concentration of solute around it using atomic force microscopy (AFM. AFM revealed bordered pit membranes as relatively smooth, soft and lacking any sharp edges surface when submerged in de-ionized water, in contrast to pictures from scanning electron microscope (SEM or AFM performed on air dry material. Exposure of the bordered pit membranes to 50 mM KCl solution resulted in significant changes in both surface physical properties with and elevation features as bordered pit membrane became harder, with visible edges of fibers and collapsed, while no change in porosity was observed. Analysis suggests a need for a major shift in our understanding to the physical bases of variable xylem resistance from change in porosity to change in pathway length. Findings support the role of actuating properties of hybrid hydrogel-cellulose materials in water redistribution and embolism resistance.

The purpose of the roundtable was to gather public health professionals and government agency representatives at the state, provincial, and local levels to identify unmet cross-border emergency preparedness and response needs and develop strategies for addressing these needs. Representatives from six state and local public health departments and three provincial governments were invited to identify cross-border needs and issues using a nominal group process. The result of the roundtable was identification of the needs considered most important and most doable across all the focus groups. The need to collaborate on and exchange plans and protocols among agencies was identified as most important and most doable across all groups. Development of contact protocols and creation and maintenance of a contact database was also considered important and doable for a majority of groups. Other needs ranked important across the majority of groups included specific isolation and quarantine protocols for multi-state responses; a system for rapid and secure exchange of information; specific protocols for sharing human resources across borders, including emergency credentials for physicians and health care workers; and a specific protocol to coordinate Strategic National Stockpile mechanisms across border communities.

    Root border cells separate from plant root tips and disperse into the soil environment. In most species, each root tip can produce thousands of metabolically active cells daily, with specialized patterns of gene expression. Their function has been an enduring mystery. Recent studies suggest that border cells operate in a manner similar to mammalian neutrophils: Both cell types export a complex of extracellular DNA (exDNA) and antimicrobial proteins that neutralize threats by trapping pathogens and thereby preventing invasion of host tissues. Extracellular DNases (exDNases) of pathogens promote virulence and systemic spread of the microbes. In plants, adding DNase I to root tips eliminates border cell extracellular traps and abolishes root tip resistance to infection. Mutation of genes encoding exDNase activity in plant-pathogenic bacteria (Ralstonia solanacearum) and fungi (Cochliobolus heterostrophus) results in reduced virulence. The study of exDNase activities in plant pathogens may yield new targets for disease control.

    The survival of a plant depends upon the capacity of root tips to sense and move towards water and other nutrients in the soil. Perhaps because of the root tip's vital role in plant health, it is ensheathed by large populations of detached somatic cells - root 'border' cells - which have the ability to engineer the chemical and physical properties of the external environment. Of particular significance, is the production by border cells of specific chemicals that can dramatically alter the behavior of populations of soilborne microflora. Molecular approaches are being used to identify and manipulate the expression of plant genes that control the production and the specialized properties of border cells in transgenic plants. Such plants can be used to test the hypothesis that these unusual cells act as a phalanx of biological 'goalies', which neutralize dangers to newly generated root tissue as the root tip makes its way through soil.

  19. State borders in ETRS89 coordinates – reality or fiction ?

    2015-12-01

    Full Text Available Common unique ETRS89 coordinates of the state boundaries are crucial for cross-border data harmonization for international projects. In the frame of European Location Framework (ELF project Czech Office for Surveying, Mapping and Cadastre (ČÚZK cooperates with Poland on egde-matching on the state border. During the preliminary phase of the project was some difficulty identified. If the state boundary is measured and administered in the national coordinate system, the accuracy of the transformation into the ETRS89 is influenced by discrepancies of the local trigonometric network, which results in two slightly different state boundaries. Final solution for Europe – international treaties on the state borders based on the ETRS89 coordinates – is necessary, but it will take years.

    Recent investigations on the bifurcations in switching circuits have shown that many atypical bifurcations can occur in piecewise smooth maps which can not be classified among the generic cases like saddle-node, pitchfork or Hopf bifurcations occurring in smooth maps. In this paper we first present experimental results to establish the theoretical problem: the development of a theory and classification of the new type of bifurcations resulting from border collision. We then present a systematic analysis of such bifurcations by deriving a normal form --- the piecewise linear approximation in the neighborhood of the border. We show that there can be eleven qualitatively different types of border collision bifurcations depending on the parameters of the normal form, and these are classified under six cases. We present a partitioning of the parameter space of the normal form showing the regions where different types of bifurcations occur. This theoretical framework will help in explaining bifurcations in all syst...

    The importance of inter-regional cooperation and innovation are widely accepted in the development rhetoric of the European Union. The highlighted importance of both themes in the context of borderlands has recently led to the coining of a new concept, cross-border regional innovation system....... However, little attention has been given to the empirical analysis of the concept. This paper suggests a framework for empirically validating the concept by examining the levels of integration between cross-border regions. The outcome is a proposed framework can be operationalized by measurable indicators...... of cross-border cooperation in a regional innovation system setting. The framework was further tested with illustrative empirical cases that demonstrate its feasibility....

  2. Block-bordered diagonalization and parallel iterative solvers

    Alvarado, F.; Dag, H.; Bruggencate, M. ten [Univ. of Wisconsin, Madison, WI (United States)

    1994-12-31

    One of the most common techniques for enhancing parallelism in direct sparse matrix methods is the reorganization of a matrix into a blocked-bordered structure. Incomplete LDU factorization is a very good preconditioner for PCG in serial environments. However, the inherent sequential nature of the preconditioning step makes it less desirable in parallel environments. This paper explores the use of BBD (Blocked Bordered Diagonalization) in connection with ILU preconditioners. The paper shows that BBD-based ILU preconditioners are quite amenable to parallel processing. Neglecting entries from the entire border can result in a blocked diagonal matrix. The result is a great increase in parallelism at the expense of additional iterations. Experiments on the Sequent Symmetry shared memory machine using (mostly) power system that matrices indicate that the method is generally better than conventional ILU preconditioners and in many cases even better than partitioned inverse preconditioners, without the initial setup disadvantages of partitioned inverse preconditioners.

    The consumption of electricity by maquiladora industries in the Mexican border states is an important driver for determining future powerplant needs in that area. An industrial electricity forecasting model is developed for the border states' maquiladoras, and the outputs are compared with a reference forecasting model developed for the US industrial sector, for which considerably more data are available. This model enables the prediction of the effect of implementing various energy efficiency measures in the industrial sector. As an illustration, here the impact of implementing energy-efficient lighting and motors in the Mexican border states' maquiladoras was determined to be substantial. Without such energy efficiency measures, electricity consumption for these industries is predicted to rise by 64% from 2001 to 2010, but if these measures are implemented on a gradual basis over the same time period, electricity consumption is forecast to rise by only 36%.

    Teeth are composed of two domains, the enamel-covered crown and the enamel-free root. The understanding of the initiation and regulation of crown and root domain formation is important for the development of bioengineered teeth. In most teeth the crown develops before the root, and erupts to the oral cavity whereas the root anchors the tooth to the jawbone. However, in the continuously growing mouse incisor the crown and root domains form simultaneously, the crown domain forming the labial and the root domain the lingual part of the tooth. While the crown-root border on the incisor distal side supports the distal enamel extent, reflecting an evolutionary diet adaptation, on the incisor mesial side the root-like surface is necessary for the attachment of the interdental ligament between the two incisors. Therefore, the mouse incisor exhibits a functional distal-mesial asymmetry. Here, we used the mouse incisor as a model to understand the mechanisms involved in the crown-root border formation. We analyzed the cellular origins and gene expression patterns leading to the development of the mesial and distal crown-root borders. We discovered that Barx2, En1, Wnt11, and Runx3 were exclusively expressed on the mesial crown-root border. In addition, the distal border of the crown-root domain might be established by cells from a different origin and by an early Follistatin expression, factor known to be involved in the root domain formation. The use of different mechanisms to establish domain borders gives indications of the incisor functional asymmetry.

  7. Conception of integrator in cross-border E-commerce

    2016-03-01

    Full Text Available Background:  E-commerce is one of the most dynamic and important sectors of the economy. The latest trend in this market is cross-border trade. It is based on selling products to customers who are located in other countries. However, it is connected to several problems, such as a high cost and long time of delivery, language barriers, different legal and tax conditionings, etc. Methods: The studies were conducted on the basis of the authors' experience in the field of e-commerce. The issue of cross-border commerce was mainly analysed with the use of reports of the European Commission. The aim of the article is to propose a conception of an integrator of cross-border e-commerce, which will make it possible, among other things, to solve logistic problems. Results: The article presents an authorial conception of an integrator in cross-border e-commerce. Its main task is to integrate the whole supply chain. Thanks to the economies of scale, obtained as a result of consolidation of parcels from many e-shops, the integrator is able to achieve lower delivery costs in international transport, make returns of goods more effective and serve customers from different countries better. Conclusions: The conception of an integrator in cross-border commerce proposed in the article may increase competitiveness of micro and small e-enterprises, especially in the international arena. Moreover, applying this conception may contribute to a rise in the attractiveness of cross-border commerce, which, as result of a greater sale level, would contribute to an increase in the total e-commerce.

    Full Text Available Tamaulipas presents a long tradition of rural migration to the United States in search of farm employment. Until the eighties Tamaulipas’ undocumented workers crossed the border easily. However, from the nineties, as a result of a restrictive migration policy centered exclusively on the “supply–side” to cross the border has become intricate. As a result, most part of immigrants is using the services of “smuggles”. This paper analyses the impact of the militarization of the frontier on the emigration of Tamaulipas’ illegal rural workers seeking for farm jobs in the United States.

    Cell movements are essential for animal development and homeostasis but also contribute to disease. Moving cells typically extend protrusions towards a chemoattractant, adhere to the substrate, contract and detach at the rear. It is less clear how cells that migrate in interconnected groups in vivo coordinate their behaviour and navigate through natural environments. The border cells of the Drosophila melanogaster ovary have emerged as an excellent model for the study of collective cell movement, aided by innovative genetic, live imaging, and photomanipulation techniques. Here we provide an overview of the molecular choreography of border cells and its more general implications.

    The exploitation of minerals has played a significant role in population growth and development of the U.S.Mexico border region. Recent proposed changes in regulations related to mining in the United States and changes in mining and investment regulations in Mexico have led to increased mineral exploration and development in Mexico, especially in the border region. As a preliminary step in the study of the mineral industry of this area, the Center for Inter-American Mineral Resource Investigations (CIMRI) of the U.S. Geological Survey has compiled mine and occurrence data for nonfuel minerals in the border region. Analysis of this information indicates that a wide variety of metallic and industrial mineral commodities are present which can be used in agriculture, infrastructure, environmental improvement, and other industries. Therefore, mining will continue to play a significant role in the economy of this region.

    In its eighth report to the President and Congress of the United States, the Good Neighbor Environmental Board (an independent federal advisory committee, that advises the President and Congress on environmental practices and infrastructure needs along the U.S. border with Mexico) noted that management of water resources issues along the U.S. border with Mexico would be aided by data and information sharing. They encouraged agencies and institutions to make data accessible, and to exchange data and information, even on a limited or ad hoc basis, in order to build trust and the capacity for managers and staff on both sides of the border to collaborate and work together to solve problems of mutual interest. Although climate is merely one factor affecting decision makers, it can often be the "straw that breaks the camel's back." Along the arid and semiarid U.S. border with Mexico, population growth, industrialization, increasing water consumption, and other factors have exacerbated societal vulnerability to naturally occurring persistent climate phenomena, such as drought. In 2006, scientists from institutions in the U.S. and Mexico agreed to collaborate to address decision makers' pressing needs for climate information, by developing a climate diagnostic and outlook product in a format usable and easily accessible by managers and policy makers. The Border Climate Summary (Resumen del Climate de la Frontera), modeled after monthly climate newsletters produced in the U.S., provides a tangible and simple information tool to strengthen the basic capacity for climate information to be usefully incorporated into decision processes. The Summary provides forecasts and value-added information on temperature, precipitation, and drought within the region. However, in order for the Summary to be effective at reaching its intended audiences, collaborators must break through barriers posed by regulatory and institutional control. They must also identify key insertion points for

    Due to international commerce, cross-border conflicts, and corruption, a holistic, information driven, approach to border security is required to best understand how resources should be applied to affect sustainable improvements in border security. The ability to transport goods and people by land, sea, and air across international borders with relative ease for legitimate commercial purposes creates a challenging environment to detect illicit smuggling activities that destabilize national level border security. Smuggling activities operated for profit or smuggling operations driven by cross border conflicts where militant or terrorist organizations facilitate the transport of materials and or extremists to advance a cause add complexity to smuggling interdiction efforts. Border security efforts are further hampered when corruption thwarts interdiction efforts or reduces the effectiveness of technology deployed to enhance border security. These issues necessitate the implementation of a holistic approach to border security that leverages all available data. Large amounts of information found in hundreds of thousands of documents can be compiled to assess national or regional borders to identify variables that influence border security. Location data associated with border topics of interest may be extracted and plotted to better characterize the current border security environment for a given country or region. This baseline assessment enables further analysis, but also documents the initial state of border security that can be used to evaluate progress after border security improvements are made. Then, border security threats are prioritized via a systems analysis approach. Mitigation factors to address risks can be developed and evaluated against inhibiting factor such as corruption. This holistic approach to border security helps address the dynamic smuggling interdiction environment where illicit activities divert to a new location that provides less resistance

    Estimating the turnover time of tree fine roots is crucial for modelling soil organic matter dynamics, but it is one of the biggest challenges in soil ecology and one of the least understood aspects of the belowground carbon cycle. The methods used - ranging from radiocarbon to ingrowth cores and root cameras (minirhizotrons) - yield very diverse pictures of fine root dynamics in forest ecosystems with turnover rates reaching from less than one year to decades. These have huge implications on estimates of carbon allocation to root growth and maintenance and on the persistence of root carbon in soils before it is decomposed or leached. We will present a new approach, involving techniques to study plant anatomy, which unravels the "real age" of fine roots. For a range of forests with diverse water and nutrient limitations located at different latitudes, we investigated the annual growth rings in the secondary xylem of thin transversal sections of fine roots belonging to tree species which form distinct growth rings. In temperate forests we find mean root "ring ages" of 1-2 years while in sub-arctic forests living fine roots can also persist for several years. The robustness of these results were tested by counting the maximum yearly growth rings in tree seedlings of known age and by counting the maximum number of growth rings of fine roots grown in ingrowth cores which were kept in temperate forest soils for one and two years. Radiocarbon estimates of mean "carbon ages", which define the time elapsed since structural carbon was fixed from the atmosphere, instead average around a decade in root systems of temperate forests (mixture of newly produced and older living roots). This dramatic difference may not be related to methodological bias, but to a time lag between C assimilation and production of a portion of fine root tissues due to the storage of older carbon components. The time lag depends very likely on tree species and environmental conditions. We further

    The characterization and control of emissions from combustion sources are of significant importance in improving local and regional air quality. Such emissions include fine particulate matter, organic carbon compounds, and NO{sub x} and SO{sub 2} gases, along with mercury and other toxic metals. This project involved four activities including Further Development of Analytical Techniques for PM{sub 10} and PM{sub 2.5} Characterization and Source Apportionment and Management, Organic Carbonaceous Particulate and Metal Speciation for Source Apportionment Studies, Quantum Modeling, and High-Potassium Carbon Production with Biomass-Coal Blending. The key accomplishments included the development of improved automated methods to characterize the inorganic and organic components particulate matter. The methods involved the use of scanning electron microscopy and x-ray microanalysis for the inorganic fraction and a combination of extractive methods combined with near-edge x-ray absorption fine structure to characterize the organic fraction. These methods have direction application for source apportionment studies of PM because they provide detailed inorganic analysis along with total organic and elemental carbon (OC/EC) quantification. Quantum modeling using density functional theory (DFT) calculations was used to further elucidate a recently developed mechanistic model for mercury speciation in coal combustion systems and interactions on activated carbon. Reaction energies, enthalpies, free energies and binding energies of Hg species to the prototype molecules were derived from the data obtained in these calculations. Bimolecular rate constants for the various elementary steps in the mechanism have been estimated using the hard-sphere collision theory approximation, and the results seem to indicate that extremely fast kinetics could be involved in these surface reactions. Activated carbon was produced from a blend of lignite coal from the Center Mine in North Dakota and

    The boundary between the United States and Mexico was created for convenient expediency through political debate and agreements (fig. 1–1). With the exception of the eastern segment of the border, which follows the course of the Rio Grande (known as the Rio Bravo in Mexico), the defining of this border was based on political decisions that had little concern for ecosystems, geologic features, or water—all of which span that imaginary line. However, the location of the border has had a remarkable effect on the biologic and physical systems in the border region and, in turn, has had a growing influence on what we now see as 21st century socioeconomic and environmental priorities. Because of the complex interactions of the human, ecological, political, and economic exigencies associated with this area, the status of the United States–Mexican border region, known as the Borderlands, has become an ever-present concern for most American citizens and for Mexican and United States Federal, State, and local governments.

    Type 2 diabetes mellitus (DM) is a re-emerging risk factor for TB development and adverse TB outcomes. As a follow-up of our previous study in 1998-2004, we reassessed prevalence of DM and its associated factors among 8431 TB patients using surveillance data from 2006 to 2013 for the Mexican state of Tamaulipas, across the border with Texas. Prevalence of DM was 25.2%, with an increase of at least 2.8% over the study period. Newly discovered factors associated with TB-DM (versus no DM) were lower education and higher unemployment (p < 0.001), which are reportedly associated with poorer DM management. At least 15% of the DM patients were newly-diagnosed and younger than those previously diagnosed, showing the importance of early DM diagnosis at TB clinics. TB-DM patients were more likely to have smear-positive, pulmonary (versus extra-pulmonary) and drug-resistant TB (1.9-, 3.8- and 1.4-fold, respectively). During treatment, TB-DM patients were more likely to be smear-positive, and less likely to die or abandon TB treatment. Thus, the increasing prevalence of DM among TB, and its association with low education, features of a more contagious TB, and drug resistance, highlight the need for design of TB management programs in DM patients, blood testing of all new TB patients for DM, and if positive for DM, testing for drug resistance.

    This quarterly report presents results and analysis of continuous onsite ambient fine particulate data at the North Birmingham sampling site during the January-March, 2002 study period. The continuous data include PM{sub 2.5} mass concentrations measured by TEOM, particle sulfate using the R&P 8400S monitor, particle size distributions measured by SMPS and APS monitors, and PM{sub 2.5} light scattering extinction coefficient as measured by nephelometer. Some instrumental issues were noted with the upgrade of the APS model 3320 are described in the report, as well as preliminary performance indications for the upgraded instrument. During the quarter preliminary data analysis and modeling studies were conducted to test the potential of the North Birmingham site data for source attribution analyses. Our initial assessment has continued to be optimistic in this regard due to the location of the site relative to several important classes of local and midrange emission sources. We anticipate that these analyses will provide good separations of the effects of major source classes and spatial source clusters, and will provide useful information relevant to PM{sub 2.5} implementation strategies.

    The root cap covers the tip of the root and functions to protect the root from environmental stress. Cells in the last layer of the root cap are known as border cells, or border-like cells (BLCs) in Arabidopsis (Arabidopsis thaliana). These cells separate from the rest of the root cap and are released from its edge as a layer of living cells. BLC release is developmentally regulated, but the mechanism is largely unknown. Here, we show that the transcription factor NIN-LIKE PROTEIN7 (NLP7) is required for the proper release of BLCs in Arabidopsis. Mutations in NLP7 lead to BLCs that are released as single cells instead of an entire layer. NLP7 is highly expressed in BLCs and is activated by exposure to low pH, a condition that causes BLCs to be released as single cells. Mutations in NLP7 lead to decreased levels of cellulose and pectin. Cell wall-loosening enzymes such as CELLULASE5 (CEL5) and a pectin lyase-like gene, as well as the root cap regulators SOMBRERO and BEARSKIN1/2, are activated in nlp7-1 seedlings. Double mutant analysis revealed that the nlp7-1 phenotype depends on the expression level of CEL5 Mutations in NLP7 lead to an increase in susceptibility to a root-infecting fungal pathogen. Together, these data suggest that NLP7 controls the release of BLCs by acting through the cell wall-loosening enzyme CEL5.

    This paper describes the results of transproctoscopic fine needle aspiration cytology in the diagnosis of rectal lesions. Fifty one consecutive patients referred with a presumptive diagnosis of rectal mass were subjected to proctoscopic examination when fine needle aspiration cytology, brush cytology and biopsy samples were taken. Of the 30 patients of malignancy of rectum in whom all the three sampling techniques were applied, the biopsy was positive in 27 (90%), brush cytology in 25 (83.3%) and fine needle aspiration cytology in 29 (96.6%). A combination of fine needle aspiration cytology with brush cytology gave a positive yield in 96.6% while that fine needle aspiration cytology with brush cytology gave a yield of 100%. Fine needle aspiration cytology was most helpful in infiltrative tumours. All 10 patients with secondaries in the pouch of Douglas or rectovesical pouch, and the single patient with submucosal rectal carcinoma were correctly diagnosed at fine needle aspiration cytology. There were no false positive results with fine needle aspiration cytology and no complications were encountered with the procedure. Images Figure 1 Figure 2 Figure 3 PMID:2323600

    We tested refugee camp residents on the Thailand-Myanmar border for Taenia solium infection. Taeniasis prevalence was consistent with that for other disease-endemic regions, but seropositivity indicating T. solium taeniasis was rare. Seropositivity indicating cysticercosis was 5.5% in humans, and 3.2% in pigs. Corralling pigs and providing latrines may control transmission of these tapeworms within this camp.

    Full Text Available This study quantifies the inconsistency in gauge precipitation observations across the border of Alaska and Yukon. It analyses the precipitation measurements by the national standard gauges (NWS 8-in gauge and Nipher gauge, and the bias-corrected data to account for wind effect on the gauge catch, wetting loss and trace events. The bias corrections show a significant amount of errors in the gauge records due to the windy and cold environment in the northern areas of Alaska and Yukon. Monthly corrections increase solid precipitation by 135 % in January, 20 % for July at the Barter Island in Alaska, and about 31 % for January and 4 % for July at the Yukon stations. Regression analyses of the monthly precipitation data show a stronger correlation for the warm months (mainly rainfall than for cold month (mainly snowfall between the station pairs, and small changes in the precipitation relationship due to the bias corrections. Double mass curves also indicate changes in the cumulative precipitation over the study periods. This change leads to a smaller and inverted precipitation gradient across the border, representing a significant modification in the precipitation pattern over the northern region. Overall, this study discovers significant inconsistency in the precipitation measurements across the US and Canada border. This discontinuity is greater for snowfall than for rainfall, as gauge snowfall observations have large errors in the windy and cold conditions. This result will certainly impact regional, particularly cross borders, climate and hydrology investigations.

  2. How Neighbours Communicate: The Role of Language in Border Relations

    2014-10-01

    Full Text Available This paper reports on a study of the linguistic situation in the border region where Norway meets Russia in the north. The aim of the study was to investigate language use when contact is revitalised after a long period with closed borders. The Norwegian and Russian languages are very different in vocabulary and structure, which makes communication difficult. How are the two languages affected by extended contact and migration across the border? The study was carried out by the author and Marit Bjerkeng through interviews, a questionnaire and observation of the linguistic situations in two Norwegian communities. The results show an ongoing development where the neighbouring language is increasingly noticeable, and there is a clear link between attitudes, identity and language use. The role of public policy seems to play an important role for the developing linguistic situation, as the Barents region as a political concept introduced in the 1990s has led to cross-border contact within various fields and also inspired local language policy, contributing to cultural pride an

    Full Text Available This paper analyses the impact of the economic and financial crisis on merger and acquisition activity in Europe and the latest trends manifested on the cross-border merger and acquisition market involving European companies. Thus, a first objective of this research is to reveal the evolution of the European cross-border merger and acquisition activity in terms of dynamics, volume and structure. Another objective of this research is to reveal the short and medium term perspectives on mergers and acquisitions in Europe. Thus, under the continuous economic recovery of the European countries and the other worldwide economies, the recovery of financial markets and the growth of corporate profits, we shall witness an intensive cross-border merger and acquisition activity in Europe. The expansion engine of these operations seems to be represented by the emerging economies. This research is based on a systematic, logical and comparative analysis of scientific literature and statistical data regarding the cross-border mergers and acquisitions that involve European companies in recent years. This paper is part of the doctoral thesis Mergers and acquisitions- strategies of growth and development of enterprises.

  11. Borders in Nigeria’s Relations with Cameroun

    Directory of Open Access Journals (Sweden)

    Omolara Akinyemi

    2014-10-01

    Full Text Available Border incidences are sources of irritants in the relationships between Nigeria and Cameroun. Examples are not far-fetched from Bakassi Peninsula imbroglio leading to hostile relationship between the two countries, and subsequent ruling of Bakassi Peninsula to Cameroun by the International Court of Justice in 2002. Indeed, this also led to the revival of the Joint Cameroun-Nigeria Border Commission entrusted with the task of demarcation of the Land and Maritime boundaries between the two countries, as mandated by the 2002 judgment. However, the demarcation exercise has caused confusion and anxiety with the inhabitants of the Cross River State, Nigeria, resulting in the inability of the team to locate pillar 133A, thereby erecting a new pillar. This exercise is lacking in proper consideration of the effects on the people in the demarcation of the land boundary. Thus, the paper finds out that the demarcationof the Land boundary which the International Court of Justice perceived as the antidote to the border skirmishes between Nigeria and Cameroun is likely to generate to another border conflicts between the two countries. This is so because, the erecting of new pillars will lead to another claim of some parts of Nigeria to Cameroun. Hence, the demarcation of Land boundary if not properly checked may be an outcome of future skirmishes and chaos.

The results also brought focus to the potential contributions that DOE’s science and technology could make for solving the many difficult, multi-generational problems faced by hundreds of bi-national communities along the 2,000-mile shared border of the United States and Mexico. Efforts to address these U.S.-Mexico border issues were initially sponsored by the DOE’s Albuquerque and Carlsbad offices. In subsequent years, the U.S. Congress directed appropriations to DOE’s Carlsbad office to address public health, safety and security issues prevalent within U.S.-Mexico border communities. With ASL’s assistance, DOE’s Albuquerque office developed contacts and formed partnerships with interested U.S and Mexican government, academic, and commercial organizations. Border industries, industrial effluents, and public health conditions were evaluated and documented. Relevant technologies were then matched to environmental problem sets along the border. Several technologies that were identified and subsequently supported by this effort are now operational in a number of U.S.-Mexico border communities, several communities within Mexico’s interior states, and in other parts of Latin America. As a result, some serious public health threats within these communities caused by exposure to toxic airborne pollutants have been reduced. During this time, DOE’s Carlsbad office hosted a bilateral conference to establish a cross-border consensus on what should be done on the basis of these earlier investigative efforts. Participating border region stakeholders set an agenda for technical collaborations. This agenda was supported by several Members of Congress who provided appropriations and directed DOE’s Carlsbad office to initiate technology demonstration projects. During the following two years, more than 12 private-sector and DOE-sponsored technologies were demonstrated in partnership with numerous border community stakeholders. All technologies

  4. Crossing and Passing: Discursive Borders in Off Shoring

    Directory of Open Access Journals (Sweden)

    Sanae Elmoudden

    2009-01-01

    Full Text Available As a term in popular discourse, globalisation marks a celebrated openness of global spaces. Critics of globalisation argue that a global economy creates borders that are more discursive than territorial. A current challenge to globalisation scholars is reaching an understanding of how the many configurations of context, space, time and place created by globalisation result in new ways of organizing space and identity. Based on rich ethnographic data from an off shore call centre in Morocco and informed by interdisciplinary research on space, this paper bridges the links between territorial and discursive borders in the global social network of off shoring. Metaphorical spaces come about when dynamic configurations of contexts at territorial borders relate or are made to relate. Call centre agents use metaphorical spaces to fix the meaning of space. In this article, I identify two different metaphorical spaces: crossing and passing that help agents organize and negotiate their spaces and subsequently their identities and power relations. I suggest that agents negotiate place through space. This crossing takes place as they imbricate the Moroccan context of “L’hrig” within the continuum of the call centre. I also suggest that agents negotiate space through place. This passing occurs via the imbrication of metaphorical space of polyvalence. Crossing and passing inscribe not only a literal meaning of “movement” and “disembodiment”, but also the nuanced meaning of “movement and staying” and “disembodiment and re-embodiment” in a place where conjunctions of space, time, place and context collide. The creation of metaphorical spaces of crossing and passing suggests modification of our understanding of diaspora: attaining the diasporic space can no longer depend on physical borders alone; it must also rely on discursive borders.

  5. The effect of limited availability of N or water on C allocation to fine roots and annual fine root turnover in Alnus incana and Salix viminalis.

    2013-09-01

    The effect of limited nitrogen (N) or water availability on fine root growth and turnover was examined in two deciduous species, Alnus incana L. and Salix viminalis L., grown under three different regimes: (i) supply of N and water in amounts which would not hamper growth, (ii) limited N supply and (iii) limited water supply. Plants were grown outdoors during three seasons in covered and buried lysimeters placed in a stand structure and filled with quartz sand. Computer-controlled irrigation and fertilization were supplied through drip tubes. Production and turnover of fine roots were estimated by combining minirhizotron observations and core sampling, or by sequential core sampling. Annual turnover rates of fine roots organic carbon increased by ca. 20% at N limitation in Salix. However, future studies on fine root decomposition under various environmental conditions are required. Fine root growth responses to N or water limitation were less pronounced in Alnus, thus indicating species differences caused by N-fixing capacity and slower initial growth in Alnus, or higher fine root plasticity in Salix. A similar seasonal growth pattern across species and treatments suggested the influence of outer stimuli, such as temperature and light.

    Full Text Available In July 2012, a diverse group of US residents living near the US-Mexico border met in El Paso, Texas for a conference entitled, We the Border: Envisioning a Narrative for Our Future.  This paper describes a vision for the US-Mexico border by diverse border residents that is at odds with the widespread view of the border as a threat to the United States. These border residents viewed their region as a set of human communities with rights, capacities, and valuable insights and knowledge. They embraced an alternative vision of border enforcement that would focus on “quality” (dangerous entrants and contraband over “quantity” (mass migration enforcement.  They called for investments in the functionality and security of ports of entry, rather than in between ports of entry.  They noted the low crime rate in US border cities, and examined how policies of not mixing local law enforcement with federal immigration enforcement contributed to this achievement. They saw the border region as the key transportation and brokerage zone of the emerging, integrated North American economy. In their view, the bilingual, bicultural, and binational skills that characterize border residents form part of a wider border culture that embraces diversity and engenders creativity. Under this vision the border region is not an empty enforcement zone, but is part of the national community and its residents should enjoy the same constitutional and human rights as other US residents. The conference participants emphasized the necessity and value of accountability and oversight of central government enforcement operations, and the need for border communities to participate in federal decision-making that affects their lives. 

  8. Magnetofluidization of fine magnetite powder.

    Valverde, J M; Espin, M J; Quintanilla, M A S; Castellanos, A

    2009-03-01

    The behavior of a fluidized bed of fine magnetite particles as affected by a cross-flow magnetic field is investigated. A distinct feature of this naturally cohesive powder, as compared to noncohesive magnetic grains usually employed in magnetofluidized beds, is that the fluidized bed displays a range of stable fluidization even in the absence of an external magnetic field. Upon application of the magnetic field, the interval of stable fluidization is extended to higher gas velocities and bed expansion is enhanced. We have measured the tensile strength as affected by application of the external magnetic field according to two different operation modes. In the H off-on operation mode, the bed is driven to bubbling in the absence of external magnetic field. Once the gas velocity is decreased below the bubbling onset and the bed has returned to stable fluidization due to natural cohesive forces, the field is applied. In the H on-on mode, the field is maintained during the whole process of bubbling and return to stable fluidization. It is found that the tensile strength of the naturally stabilized bed is not essentially changed by application of the field ( H off-on) since the magnetic field cannot alter the bed structure once the particles are jammed in the stable fluidization state. Magnetic forces within the bulk of the jammed bed are partially canceled as a result of the anisotropic nature of the dipole-dipole interaction between the particles, which gives rise to just a small increment of the tensile strength. On the other hand, when the field is held on during bubbling and transition to stable fluidization ( H on-on mode), the tensile strength is appreciably increased. This suggests the formation of particle chains when the particles are not constrained due to the dipole-dipole attractive interaction which affects the mechanical strength of the stably fluidized bed. Experimental data are analyzed in the light of theoretical models on magnetic surface stresses.

    Understanding the flow of fines in porous media and fractured media is significant for industrial, environmental, geotechnical and petroleum technologies to name a few. Several models have been proposed to simulate the flow and transport of fines using single or two-phase flow approaches while other models rely on mobile and immobile transport approaches. However, to the authors' best knowledge, all the proposed modeling approaches have not been compared to each other in order to define their limitations and domain of validation. In the present study, several models describing the transport of fines in heterogeneous porous and fractured media will be presented and compared to each other. Furthermore, we will evaluate their performance on the same published experimental sets of published data.

    Full Text Available Fine particulate matter has become the premier air pollutant of Beijing in recent years, enormously impacting the environmental quality of the city and the health of the residents. Fine particles with aerodynamic diameters of 0~0.3 μm, 0.3~0.5 μm, and 0.5~1.0 μm, from the yeasr 2007 to 2012, were monitored, and the hospital data about respiratory diseases during the same period was gathered and calculated. Then the correlation between respiratory health and fine particles was studied by spatial analysis and grey correlation analysis. The results showed that the aerial fine particulate matter pollution was mainly distributed in the Zizhuyuan sub-district office. There was a certain association between respiratory health and fine particles. Outpatients with respiratory system disease in this study area were mostly located in the southeastern regions (Balizhuang sub-district office, Ganjiakou sub-district office, Wanshoulu sub-district office, and Yongdinglu sub-district office and east-central regions (Zizhuyuan sub-district office and Shuangyushu sub-district office of the study area. Correspondingly, PM1 (particulate matter with aerodynamic diameter smaller than 1.0 um concentrations in these regions were higher than those in any other regions. Grey correlation analysis results showed that the correlation degree of the fine particle concentration with the number of outpatients is high, and the smaller fine particles had more obvious effects on respiratory system disease than larger particles.

  16. Pastoralists at War: Violence and Security in the Kenya-Sudan-Uganda Border Region

    Directory of Open Access Journals (Sweden)

    Jonah Leff

    2009-12-01

    Full Text Available The majority of those living in the border region of Kenya, Sudan, and Uganda are pastoralists, whose livelihoods are dictated by the upkeep and size of their herds. Harsh environmental conditions force pastoralists to migrate in search of water and pasturelands during the dry season. With limited access to water and competing rights to land, intertribal conflict arises when pastoralists from one tribe enter the territory of another. The increased availability of small arms in the region from past wars increasingly makes ordinary clashes fatal. Governments in the region have responded with heavy-handed coercive disarmament operations. These have led to distrust and subsequent violent clashes between communities and security providers. This report reviews the scale, consequences of, and responses to the many pastoral conflicts, utilizing methodological tools such as key informant interviews, retrospective analysis, and a thorough review of available literature.

  17. INTERACTIONS BETWEEN CATIONIC POLYELECTROLYTE AND PULP FINES

    Directory of Open Access Journals (Sweden)

    2011-05-01

    Full Text Available Papermaking pulps are a mixture of fibres, fibre fragments, and small cells (parenchyma or ray cells, usually called pulp fines. The interactions between pulp fines and a cationic copolymer of acrylamide and acryloxyethyltrimethyl ammonium chloride were investigated based on solid-liquid isotherms prepared under different turbulence, and subsequent advanced surface characterization using X-ray photoelectron spectroscopy (XPS and time-of-flight secondary ion mass spectrometry (ToF-SIMS. The surface charge and surface area of pulp fine substrates were measured by methylene blue sorption-XPS analysis and nitrogen adsorption combined with mercury porosimetry, respectively. The driving force behind polyelectrolyte adsorption was the amount of the surface anionic charge, whereas surface area appeared to be of less importance. Based on a comparison of solid-liquid and XPS sorption isotherms, different polyelectrolyte conformations were suggested, depending on the types of fines: A flatter conformation and partial cell-wall penetration of polyelectrolytes on kraft fines from freshly prepared pulp, and a more free conformation with extended loops and tails on lignocellulosic fines from recycled pulp. Additionally, ToF-SIMS imaging proved that recycled pulp fines contained residual de-inking chemicals (primarily palmitic acid salts that possibly hinder the electrostatic interactions with polyelectrolytes.

  18. Discovery of the copper deposits with features of the Keweenawan type in the border area of Yunnan and Guizhou provinces

    朱炳泉; 胡耀国; 张正伟; 常向阳

    2003-01-01

    There existed intense Cu anomaly on the northeastern side of the geochemical boundary with NW strike in the border area between the Yunnan and Guizhou provinces. Through field observation, ore bodies of high-grade native coppers have been found. The copper mineralization was constrained by the ancient volcanic vents of Permian basalt eruption and the overlain strata of carbonaceous argillites. Native coppers with flaky, net veined and impregnated occurrences, fine-grained tenorites and massive chalcocites widely occur in volcanic breccias, tuffs, carbonaceous-siliceous argillites and siliceous bitumen rocks with bed thickness of about 15-80 m. Cu contents vary from 0.5% to 20%. The copper mineralization was tightly related to actinolite-tremolitization, zeolitization and bituminization and involved in extensive reduction environments. Continental flood basalts erupted in mantle plume environments usually have high Cu concentrations (~170 ×10-6 in the Emeishan basalts), which provided a copper source of mineralization. Thus, metallogenesis of the native copper deposits in the Yunnan-Guizhou border area is tightly associated with intensive crust-mantle and organic-inorganic interactions. The tremolitization and chalcocitization indicate that the metallogenic temperatures are in a range of 400-100℃. The geologic background and characteristics of ore and alteration for the native copper deposits in this area are somewhat similar to those of the Keweenawan native copper deposit in Michigan, USA.

  6. A comparative assessment of contaminants in fish from four resacas of the Texas, USA-Tamaulipas, Mexico border region.

    2001-07-01

    A recent survey of contaminant information for the Lower Rio Grande Valley (LRGV), Texas, has shown that little is known about contaminants and their impacts on biota of resacas (oxbows) along the US-Mexico border. In 1996, fish were collected from four resacas in the Texas-Tamaulipas border region to assess contaminant loadings and their impacts on fish and birds. Tissue residue concentrations in fish were analyzed and also compared to two histopathological bioindicators of unhealthy environmental conditions. Of the organochlorine insecticides measured, DDE was the most common and was present at relatively high concentrations (10 microg/g w/w) at some sites. DDE concentrations were nearly 20 times greater in fish from resacas in Texas than from resacas in Tamaulipas, although the limited sample sizes obtained precluded statistical comparisons. DDE concentrations in fish from the two Texas resacas were also greater than those reported in fish from nearby areas during the 1980s and 1990s. Most trace element concentrations were similar among resacas from Texas and Tamaulipas. Arsenic, however, was two to six times greater in fish from a downtown resaca in Matamoros than in fish from other resacas in Tamaulipas and Texas. The bioindicators, pigment accumulation, and macrophage aggregates (MAs), in general, reflected the contamination indicated by the tissue residues for each site. Overall, it appears that some resacas of the US-Mexico border region are contaminant sinks and could pose potential health or reproductive problems for fish and wildlife, and humans that consume fish from those sites.

  8. Evaluation of Exposures to Diesel Particulate Matter Utilizing Ambient Air Monitoring and Urinary Biomarkers Among Pedestrian Commuters who Cross the U.S.-Mexico Border at San Ysidro, CA

    Science.gov (United States)

    Galaviz, Vanessa Eileen

    Background: Walk-in-line pedestrians crossing the U.S.-Mexico border northbound at the San Ysidro, CA Port of Entry ("Border Commuters") may be at an increased risk of experiencing elevated traffic-related air pollution, including diesel exhaust (DE). DE exposure has been associated with numerous adverse health effects, particularly cardiovascular and respiratory problems, including as lung cancer. Pedestrian crossers wait in line for extended periods and stand within 10 feet of highly concentrated traffic, particularly to diesel buses. Understanding the magnitude of traffic-related exposures is important for this vulnerable population. It was hypothesized that subjects who reside in Tijuana, Baja California, Mexico and cross the border as a pedestrian will experience higher exposure to traffic-related pollutants than those who live and work in South San Diego, CA, USA and do not cross the border. Methods: Ninety-one participants were enrolled for this study; 80% were "Border Commuters" and 20% were "Non-Border Commuters". "Non-Border Commuters" served as the comparison group and were defined as residents who lived in or near and worked or went to school in San Ysidro, CA but did not cross the border. Questionnaires, time activity diaries, and urine samples were collected from all participants. Of the "Border Commuters", 56 personal 24-hour PM2.5 and 1-nitropyrene (1-NP) - a marker for diesel exhaust - samples were collected. There were 22 at-home indoor and 14 at-home outdoor 1-NP samples collected. Additionally, area samples collected at the border included 35 days of 1-NP, black carbon (BC), carbon monoxide (CO), fine particulate matter (PM2.5) and ultrafine particulate matter (UFP). Of the "Non-Border Commuters", 15 personal 24-hour PM2.5 and 1-NP samples were collected. Additonally, 3 at-home indoor and outdoor 24-hour 1-NP samples were collected. Results: Personal exposure to PM2.5 was nearly 2-fold higher among "Border Commuters" compared to "Non-Border

  9. Preliminary United States-Mexico border watershed analysis, twin cities area of Nogales, Arizona and Nogales, Sonora

    2002-01-01

    The United States - Mexico border area faces the challenge of integrating aspects of its binational physical boundaries to form a unified or, at least, compatible natural resource management plan. Specified geospatial components such as stream drainages, mineral occurrences, vegetation, wildlife, and land-use can be analyzed in terms of their overlapping impacts upon one another. Watersheds have been utilized as a basic unit in resource analysis because they contain components that are interrelated and can be viewed as a single interactive ecological system. In developing and analyzing critical regional natural resource databases, the Environmental Protection Agency (EPA) and other federal and non-governmental agencies have adopted a ?watershed by watershed? approach to dealing with such complicated issues as ecosystem health, natural resource use, urban growth, and pollutant transport within hydrologic systems. These watersheds can facilitate the delineation of both large scale and locally important hydrologic systems and urban management parameters necessary for sustainable, diversified land-use. The twin border cities area of Nogales, Sonora and Nogales, Arizona, provide the ideal setting to demonstrate the utility and application of a complete, cross-border, geographic information systems (GIS) based, watershed analysis in the characterization of a wide range of natural resource as well as urban features and their interactions. In addition to the delineation of a unified, cross-border watershed, the database contains sewer/water line locations and status, well locations, geology, hydrology, topography, soils, geomorphology, and vegetation data, as well as remotely sensed imagery. This report is preliminary and part of an ongoing project to develop a GIS database that will be widely accessible to the general public, researchers, and the local land management community with a broad range of application and utility.

  10. Effects of vegetated field borders on arthropods in cotton fields in eastern North Carolina.

    Outward, Randy; Sorenson, Clyde E; Bradley, J R

    2008-01-01

    The influence, if any, of 5m wide, feral, herbaceous field borders on pest and beneficial arthropods in commercial cotton, Gossypium hirsutum (L.) (Malvales: Malvaceae), fields was measured through a variety of sampling techniques over three years. In each year, 5 fields with managed, feral vegetation borders and five fields without such borders were examined. Sampling was stratified from the field border or edge in each field in an attempt to elucidate any edge effects that might have occurred. Early season thrips populations appeared to be unaffected by the presence of a border. Pitfall sampling disclosed no differences in ground-dwelling predaceous arthropods but did detect increased populations of crickets around fields with borders. Cotton aphid (Aphis gossypii Glover) (Hemiptera: Aphididae) populations were too low during the study to adequately assess border effects. Heliothines, Heliothis virescens (F.) and Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), egg numbers and damage rates were largely unaffected by the presence or absence of a border, although in one instance egg numbers were significantly lower in fields with borders. Overall, foliage-dwelling predaceous arthropods were somewhat more abundant in fields with borders than in fields without borders. Tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois) (Heteroptera: Miridae) were significantly more abundant in fields with borders, but stink bugs, Acrosternum hilare (Say), and Euschistus servus (Say) (Hemiptera: Pentatomidae) numbers appeared to be largely unaffected by border treatment. Few taxa clearly exhibited distributional edge effects relative to the presence or absence of border vegetation. Field borders like those examined in this study likely will have little impact on insect pest management in cotton under current insect management regimens.

  20. Detecting a trend change in cross-border epidemic transmission

    Science.gov (United States)

    Maeno, Yoshiharu

    2016-09-01

    A method for a system of Langevin equations is developed for detecting a trend change in cross-border epidemic transmission. The equations represent a standard epidemiological SIR compartment model and a meta-population network model. The method analyzes a time series of the number of new cases reported in multiple geographical regions. The method is applicable to investigating the efficacy of the implemented public health intervention in managing infectious travelers across borders. It is found that the change point of the probability of travel movements was one week after the WHO worldwide alert on the SARS outbreak in 2003. The alert was effective in managing infectious travelers. On the other hand, it is found that the probability of travel movements did not change at all for the flu pandemic in 2009. The pandemic did not affect potential travelers despite the WHO alert.

  1. Border collisions inside the stability domain of a fixed point

    Science.gov (United States)

    Avrutin, Viktor; Zhusubaliyev, Zhanybai T.; Mosekilde, Erik

    2016-05-01

    Recent studies on a power electronic DC/AC converter (inverter) have demonstrated that such systems may undergo a transition from regular dynamics (associated with a globally attracting fixed point of a suitable stroboscopic map) to chaos through an irregular sequence of border-collision events. Chaotic dynamics of an inverter is not suitable for practical purposes. However, the parameter domain in which the stroboscopic map has a globally attracting fixed point has generally been considered to be uniform and suitable for practical use. In the present paper we show that this domain actually has a complicated interior structure formed by boundaries defined by persistence border collisions. We describe a simple approach that is based on symbolic dynamics and makes it possible to detect such boundaries numerically. Using this approach we describe several regions in the parameter space leading to qualitatively different output signals of the inverter although all associated with globally attracting fixed points of the corresponding stroboscopic map.

    This paper explores the issue of 'fuel tourism' in Switzerland. For the period 1985-1997, a panel data model for the border regions of Switzerland, (Italy, France, and Germany) is estimated. The results show a significant impact of the gasoline price differential on demand, suggesting that a decrease of 10% in the Swiss gasoline price leads to an increase in demand in the border areas of nearly 17.5%. It is shown that fuel tourism accounted for about 9% of overall gasoline sales in the three regions during the period 1985-1997 and that the recently proposed Swiss CO{sub 2}-tax might, given current conditions, eliminate net fuel tourism.

  5. Democracy on the Border. Freedom of Movement and Popular Sovereignty

    Directory of Open Access Journals (Sweden)

    Edoardo Greblo

    2015-06-01

    Full Text Available The idea that the sovereignty of the nation-state has collapsed under the weight of globalization "and it is now an empty shell" has long been a conviction rooted in political and social sciences, which speak openly of an era of post-sovereignty. However, the sovereignty of the State finds an ultimate and indispensable bulwark in the defense and in the border control. But as things stand when sovereignty is «popular»? What principles the democratic state of law can appeal to practice an immigration policy which unilaterally terminate the company to strangers? The thesis proposed in the article argues that the democratic theory does not consider, in this regard, any discretionary. If «the people is an aspiration, not a fact», as Benhabib argues, the regime of border control, to be democratically legitimate, should take into account both the perspective of insiders, and that of the outsiders.

  7. Experimental Study of the Possibility to Make a Mortar with Ternary Sand (Natural and Artificial Fine Aggregates)

    Science.gov (United States)

    Baali, L.; Naceri, A.; Rahmouni, Z.; Mehidi, M. W. Noui

    This experimental study investigates the possibility to make a mortar with a ternary sand (natural and artificial fine aggregates). This method is utilized to correct the particle size distribution of various sands used in mortar. For this investigation, three sands have been used: a dune sand (DS), a slag sand (SS), and brick sand (BS) at different proportions in mortar. After crushing, the artificial fine aggregate (blast furnace slag and waste brick fine aggregate) was sifted in order to use it as fine aggregate. The effect of the quality and grain size distribution of natural fine aggregate (i.e., DS) and artificial fine aggregates (i.e., SS and BS) on the physical properties of ternary sand confected (density, porosity, fineness modulus, equivalent sand, particle size distribution, water absorption) and properties of fresh and hardened mortar were analysed. In the same way for this study, the physical properties and chemical compositions of DS, SS, BS and cement were investigated. The results obtained show that the mechanical strength on mortar depends of the nature and particle size distribution of sand studied. The reuse of this recycled material (slag blast furnace and waste brick) in the industry would contribute to the protection of the environment. This study shows the potential of this method to make mortar with ternary sand (natural and artificial fine aggreagates) in order to improve the physical properties of sand. Utilising natural and artificial fine aggregates to produce quality mortar should yield significant environmental benefits.

    2016-05-01

    Full Text Available Addressing border security appears to be a plausible approach for states that suffer from terrorism. Kenya’s border wall is to keep terrorists out of Kenya. Utilizing a comparative approach, this paper explores the efficacy of border walls, particularly Kenya’s wall with Somalia. Findings show that walls rarely accomplish stated goals and have unintended consequences. In Kenya’s case, it may reignite border disputes and separate communities. The success of Kenya’s border wall is low given the high levels of corruption and the fact that walls have been demonstrated to only be as good as the people who guard them.

  1. Extracellular proteins in pea root tip and border cell exudates.

    2007-02-01

    Newly generated plant tissue is inherently sensitive to infection. Yet, when pea (Pisum sativum) roots are inoculated with the pea pathogen, Nectria haematococca, most newly generated root tips remain uninfected even though most roots develop lesions just behind the tip in the region of elongation. The resistance mechanism is unknown but is correlated spatially with the presence of border cells on the cap periphery. Previously, an array of >100 extracellular proteins was found to be released while border cell separation proceeds. Here we report that protein secretion from pea root caps is induced in correlation with border cell separation. When this root cap secretome was proteolytically degraded during inoculation of pea roots with N. haematococca, the percentage of infected root tips increased from 4% +/- 3% to 100%. In control experiments, protease treatment of conidia or roots had no effect on growth and development of the fungus or the plant. A complex of >100 extracellular proteins was confirmed, by multidimensional protein identification technology, to comprise the root cap secretome. In addition to defense-related and signaling enzymes known to be present in the plant apoplast were ribosomal proteins, 14-3-3 proteins, and others typically associated with intracellular localization but recently shown to be extracellular components of microbial biofilms. We conclude that the root cap, long known to release a high molecular weight polysaccharide mucilage and thousands of living cells into the incipient rhizosphere, also secretes a complex mixture of proteins that appear to function in protection of the root tip from infection.

The aim is to combine approaches for solving a system of polynomial equations with dual methods which involve moment matrices and semi-definite programming. While the border basis algorithms of [17] are efficient and numerically stable for computing complex roots, algorithms based on moment matrices [12] allow the incorporation of additional polynomials, e.g., to re- strict the computation to real roots or to eliminate multiple solutions. The proposed algorithm can be used to compute a border basis of the input ideal and, as opposed to other approaches, it can also compute the quotient structure of the (real) radical ideal directly, i.e., without prior algebraic techniques such as Gr\\"obner bases. It thus combines the strength of existing algorithms and provides a unified treatment for the computation of border bases for the ideal, the radical ideal and the real r...

    Modeling real-world scenarios is a challenge for traditional social science researchers, as it is often hard to capture the intricacies and dynamisms of real-world situations without making simplistic assumptions. This imposes severe limitations on the capabilities of such models and frameworks. Complex population dynamics during natural disasters such as pandemics is an area where computational social science can provide useful insights and explanations. In this paper, we employ a novel intent-driven modeling paradigm for such real-world scenarios by causally mapping beliefs, goals, and actions of individuals and groups to overall behavior using a probabilistic representation called Bayesian Knowledge Bases (BKBs). To validate our framework we examine emergent behavior occurring near a national border during pandemics, specifically the 2009 H1N1 pandemic in Mexico. The novelty of the work in this paper lies in representing the dynamism at multiple scales by including both coarse-grained (events at the national level) and finegrained (events at two separate border locations) information. This is especially useful for analysts in disaster management and first responder organizations who need to be able to understand both macro-level behavior and changes in the immediate vicinity, to help with planning, prevention, and mitigation. We demonstrate the capabilities of our framework in uncovering previously hidden connections and explanations by comparing independent models of the border locations with their fused model to identify emergent behaviors not found in either independent location models nor in a simple linear combination of those models.

    Full Text Available In this paper the border is evaluated as a fold of power relations in which sovereign capacity and competence is marshalled alongside strategies of control, surveillance, and risk management to constitute, what we call, a zone of frontier government. We advance the argument that the border is a site for both negative and positive power, for insertion and subtraction, and that the assemblage of surveillance and compliance regimes are "run" not so much in the furtherance of a precautionary or pre-emptive end-state, but as intermediate values that are sufficiently malleable by an invigorated sovereign, expressed in the residue of discretion in and between the many border agencies.  Our analysis is based on extensive policy and program documents, as well as twenty-five interviews with officials in various agencies engaged in the US-Canada and, particularly, the Windsor-Detroit corridor.

    Full Text Available The 5´-untranslated region of Pestivirus strains isolated from domestic and wild animals were analysed to determine their taxonomic status according to nucleotide changes in the secondary genomic structure using the palindromic nucleotide substitutions (PNS method. A total of 131 isolates out of 536 Pestivirus strains evaluated, were clustered as Border disease virus (BDV species. The BDV strains were further divided into at least 8 genotypes or subspecies. Thirty-two isolates from small ruminants suffering from clinical symptoms of Border disease were clustered into bovine viral diarrhoea virus 1 (BVDV-1, BVDV-2 and classical swine fever (hog cholera virus species and also into the tentative BDV-2 species. Since the definition of an infectious disease is based primarily on a specific causative pathogen and taking into account the heterogeneity of the genus Pestivirus, clinical cases should be named according to the laboratory results. The PNS procedure could be useful for laboratory diagnosis of Border disease in domestic and wild ruminants.

    Full Text Available Following the changes of regimes in Central Europe, research into border regions has been increasingly adverted. However, various suggestions of researchers came into light on the definition and role of borders. Prior to the changes of regimes, the development of cross-border tourism was counterworked by administrative tools resulting in settlements in border regions becoming peripheral. Negative effects emerged mostly at border sections demarcated between countries either not able to join (for some reason or not willing to gain access to the European Union and certain member states (occurring at the Ukrainian, Serbian, Belarusian and, in some cases, the Croatian border. In the field of cross-border cooperation, within the tourism industry, a west-to-east and north-to-south gradient can be detected that, by the present logic, can be explained by the changes of economic circumstances and the succession of European Union accession.

    2016-11-01

    As one component of a study investigating the impact of vehicle emissions on near-road air quality, human exposures, and potential health effects, particles were measured from September 21 to October 30, 2010 on both sides of a major roadway (Interstate-96) in Detroit. Traffic moved freely on this 12 lane freeway with a mean velocity of 69 mi/hr. with little braking and acceleration. The UC Davis DELTA Group rotating drum (DRUM) impactors were used to collect particles in 8 size ranges at sites nominally 100 m south, 10 m north, 100 m north, and 300 m north of the highway. Ultra-fine particles were continuously collected at the 10 m north and 100 m north sites. Samples were analyzed every 3 h for mass (soft beta ray transmission), 42 elements (synchrotron-induced x-ray fluorescence) and optical attenuation (350-800 nm spectroscopy). A three day period of steady southerly winds along the array allowed direct measurement of freeway emission rates for coarse (10 > Dp > 1.0 μm), PM2.5, very fine (0.26 > Dp > 0.09 μm), and ultra-fine (Dp car and truck emission rates of 1973, this value would have been about 16 μg/m3, corrected down from the 19 μg/m3 PM5.0 using measured roadway dust contributions. This would have included 2.7 μg/m3 of lead, versus the 0.0033 μg/m3 measured. Very fine particles were distributed across the array with a relatively weak falloff versus distance. For the ultra-fine particles, emissions of soot and metals seen in vehicular braking studies correlated with traffic at the 10 m site, but only the soot was statistically significant at the 100 m north site. Otherwise, the 10 m north and 100 m north sites were essentially identical in mean concentration and highly correlated in time for most of the 5 week study. This result supports earlier publications showing the ability of very fine and ultra-fine particles to transport to sites well removed from the freeway sources. The concentrations of very fine and ultra-fine metals from brake wear and

    The dramatic increase in marine bio-invasions, particularly of non-indigenous ascidians, has highlighted the vulnerability of marine ecosystems and the productive sectors that rely on them. A critical issue in managing invasive species is determining the relative roles of ongoing introductions, versus the local movement of propagules from established source populations. Styela clava (Herdman, 1882), the Asian clubbed tunicate, once restricted to the Pacific shores of Asia and Russia, is now abundant throughout the northern and southern hemispheres and has had significant economic impact in at least one site of incursion. In 2005 S. clava was identified in New Zealand. The recent introduction of this species, coupled with its restricted distribution, provided an ideal model to compare and contrast the introduction and expansion process. In this study, the mitochondrial DNA cytochrome oxidase subunit I gene (COI) gene and 11 microsatellite markers were used to test the regional genetic structure and diversity of 318 S. clava individuals from 10 populations within New Zealand. Both markers showed significant differentiation between the northern and southern populations, indicative of minimal pre- or post-border connectivity. Additional statistics further support pre- and post-border differentiation among Port and Harbour populations (i.e. marinas and aquaculture farms). We conclude that New Zealand receives multiple introductions, and that the primary vector for pre-border incursions and post-border spread is most likely the extensive influx of recreational vessels that enter northern marinas independent of the Port. This is a timely reminder of the potential for hull-fouling organisms to expand their range as climates change and open new pathways.

  12. How Borders Come to Matter? The "Physicality" of the Border in Gloria Anzaldúa’s "Borderlands/La Frontera"

    2015-06-01

    Full Text Available http://dx.doi.org/10.5007/2175-7917.2015v20n2p181 In this piece I attempt to address the ways in which Gloria Anzaldúa, in Borderlands: La Frontera (2007, negotiates the idea of the border as having both discursive and material dimensions. In creating a new mestiza consciousness from the borderland, which is the space that is affected by the borderline, Anzaldúa develops concepts and ideas that can be linked to Donna Haraway’s articulation of the cyborg and to Karen Barad’s theory of an agential realist ontology in the sense that Anzaldúa engages creatively with contradicting parts of her identity in a cyborgian fashion, and sees the enactment of borders as both limiting and empowering, as having emotional and material effects. Anzaldúa then addresses these effects and demonstrates how she applies them in the fabrication of a new consciousness, the consciousness of the new mestiza. In this work, therefore, I explore how the border makes itself physically present in Anzaldúa’s Borderlands and how the discursive meets matter; and I do this by finding common threads and possible connections among the works of Anzaldúa, Haraway, and Barad.

  13. A Modelling Approach on Fine Particle Spatial Distribution for Street Canyons in Asian Residential Community

    2016-04-01

    Rapidly increasing urban pollution poses severe health risks.Especially fine particles pollution is considered to be closely related to respiratory and cardiovascular disease. In this work, ambient fine particles are studied in street canyons of a typical Asian residential community using a computational fluid dynamics (CFD) dispersion modelling approach. The community is characterised by an artery road with a busy traffic flow of about 4000 light vehicles (mainly cars and motorcycles) per hour at rush hours, three streets with hundreds light vehicles per hour at rush hours and several small lanes with less traffic. The objective is to study the spatial distribution of the ambient fine particle concentrations within micro-environments, in order to assess fine particle exposure of the people living in the community. The GRAL modelling system is used to simulate and assess the emission and dispersion of the traffic-related fine particles within the community. Traffic emission factors and traffic situation is assigned using both field observation and local emissions inventory data. High resolution digital elevation data (DEM) and building height data are used to resolve the topographical features. Air quality monitoring and mobile monitoring within the community is used to validate the simulation results. By using this modelling approach, the dispersion of fine particles in street canyons is simulated; the impact of wind condition and street orientation are investigated; the contributions of car and motorcycle emissions are quantified respectively; the residents' exposure level of fine particles is assessed. The study is funded by "Taiwan Megacity Environmental Research (II)-chemistry and environmental impacts of boundary layer aerosols (Year 2-3) (103-2111-M-001-001-); Spatial variability and organic markers of aerosols (Year 3)(104-2111-M-001 -005 -)"

    Injection drug use is of increasing concern along the US-Mexico border where Tijuana and Ciudad (Cd.) Juarez are located. Methamphetamine has long been manufactured and trafficked through Mexico, with low rates of use within Mexico. With methamphetamine use now considered epidemic in the United States, and with associated individual and community harms such as HIV, STDs, domestic violence and crime, there is concern that rates of methamphetamine in the Northwestern border regions of Mexico may be rising. We conducted a qualitative study to explore the context of injection drug use in Tijuana and Cd. Juarez and included questions about methamphetamine. Guided in-depth interviews were conducted with 10 male and 10 female injection drug users (IDUs) in Tijuana and 15 male and 8 female IDUs in Cd. Juarez (total N = 43). Topics included types of drug used, injection settings, access to sterile needles and environmental influences. Interviews were taped, transcribed verbatim and translated. Content analysis was conducted to identify themes. The median age of injectors in both cities was 30. Methamphetamine was injected, either alone or in combination with other drugs by injectors in both Tijuana (85%) and Cd. Juarez (17%) in the 6 months previous to interview. Several important themes emerged with respect to methamphetamine use in both cities. IDUs in both cities considered methamphetamine to be widely used in Tijuana and infrequently used in Cd. Juarez, while the converse was true for cocaine. In both cities, stimulant (either cocaine or methamphetamine) use was widespread, with 85% in Tijuana and 83% in Cd. Juarez reporting current use of a stimulant, most often used in combination with heroin. Some injectors reported knowledge of local manufacturing and one had direct experience in making methamphetamine; some cross-border use and trafficking was reported. Injectors reported concerns or experience with serious health effects of methamphetamine such as abscesses or

  20. The insulator protein SU(HW fine-tunes nuclear lamina interactions of the Drosophila genome.

    Directory of Open Access Journals (Sweden)

    Joke G van Bemmel

    Full Text Available Specific interactions of the genome with the nuclear lamina (NL are thought to assist chromosome folding inside the nucleus and to contribute to the regulation of gene expression. High-resolution mapping has recently identified hundreds of large, sharply defined lamina-associated domains (LADs in the human genome, and suggested that the insulator protein CTCF may help to demarcate these domains. Here, we report the detailed structure of LADs in Drosophila cells, and investigate the putative roles of five insulator proteins in LAD organization. We found that the Drosophila genome is also organized in discrete LADs, which are about five times smaller than human LADs but contain on average a similar number of genes. Systematic comparison to new and published insulator binding maps shows that only SU(HW binds preferentially at LAD borders and at specific positions inside LADs, while GAF, CTCF, BEAF-32 and DWG are mostly absent from these regions. By knockdown and overexpression studies we demonstrate that SU(HW weakens genome - NL interactions through a local antagonistic effect, but we did not obtain evidence that it is essential for border formation. Our results provide insights into the evolution of LAD organization and identify SU(HW as a fine-tuner of genome - NL interactions.

    The enhancement of the charge neutrality due to the existence of fine particles is shown to occur generally under microgravity and in one-dimensional structures under gravity. As an application of the latter, the size and position of fine particle clouds relative to surrounding plasmas are determined under gravity.

    The recovery and utilization of coal fines, both impounded and in cleaning plant effluent streams, have received close attention from both coal producers and coal-fixed utilities during the last few years. Many coal producers view impounded fines as an environmental liability and the discarded fines in plant effluent streams as contributing to a loss in Btu recovery. In addition, the rejected coal fines increase the quantity and cost of refuse disposal. The handleability of fine coal has always been a problem. Dewatering cleaned fine coal is costly. Excessive fugitive dust emissions are commonly associated with handling dry fine coal. Wet fine coal sticks to conveyor belts, blocks fuel chutes, and may limit pulverizer capacity. The preparation of coal water slurry fuel (CWSF) from wet coal fines alleviates the necessity of drying while at the same time eliminates the flow problems that wet fine coal poses to the end user. Furthermore, the utilization of CWSF as an opportunity fuel converts coal fines into a revenue source rather than a liability. Several utilities are evaluating the co-firing of low solids, low viscosity CWSF with their normal coal feedstock in an effort to lower fuel cost and/or as a NO{sub x} reduction technique. The utilization of this opportunity fuel is being driven by a changing electric industry in which utilities continually strive to reduce plant emissions while simultaneously reducing their operating costs to become more competitive as the generation side of the industry prepares for deregulation.

    The studies regarding fine art reproduction mainly focus on the accuracy of colour and the recreation of surface texture properties. Since reflection properties other than colour are neglected, important details of the artwork are lost. For instance, gloss properties, often characteristic to painters and particular movements in the history of art, are not well reproduced. The inadequate reproduction of the different gloss levels of a piece of fine art leads to a specular reflection mismatch in printed copies with respect to the original works that affects the perceptual quality of the printout. We used different print parameters of a 3D high resolution printing setup to control the gloss level on a printout locally. Our method can be used to control gloss automatically and in crucial applications such as fine art reproduction.

  5. Sustainable rural development and cross-border cooperation

    2009-01-01

    Full Text Available The concept of sustainable rural development comprises three aspects - social, economical and ecological. They are supposed to act in synergy, but, at the same time, these aspects are supposed to be competitive. Agriculture, as a traditional activity of rural economy, contributes to the sustainable development of rural areas only if there is an adequate resources management. If not, there will be a significant degradation of rural environment. These are the reasons why sustainable agriculture development is emphasized since it maximizes productivity and minimizes negative effects on nature and human resources. In this context, one should observe the connection between agriculture and tourism existing in the EU, where the application of sustainable agricultural development concept produces external effects connected to biodiversity protection and environment in rural areas. These become a good foundation for the development of rural and ecotourism. EU enlargement induced diversification of support programmes that EU gives to the candidate countries, as well as to those who are just entering the process of stabilization and association to the EU. Through cross-border cooperation projects, many goals can be accomplished, among which aspiration for promotion of sustainable economical and social development in border regions is one of the leading. Knowing that these regions are usually passive and underdeveloped, the projects of cross-border cooperation could induce development of those activities in local economy, which could bring better living conditions and economic prosperity on the one hand, and protection of environment on the other. Examples of this kind of projects in Serbia can usually be found in rural and ecotourism development.

  6. Creditor protection in cross-border mergers; unfinished business

    2008-03-01

    Full Text Available In cross-border mergers, creditor protection is important to facilitate a smooth, efficient and transparent process necessary to facilitate the single market. As all assets and liabilities are being transferred and there is a risk that the liabilities of the acquiring company will exceed the assets, creditor protection needs to be safeguarded in legal mergers. As the title suggests, creditor protection in the context of cross-border mergers and the recently adopted directive is examined in this paper, as well as the position of creditors under Dutch law and the Third Directive. The ex-ante and ex-post systems of creditor protection, both existing in the Member States of the EU, and which are both supported by strong arguments, are also discussed. The fact that differences in creditor protection rules nevertheless remain may create unjustifiable differences in the position of various groups of creditors involved in one single cross-border merger. The authors conclude that the case for leaving creditor protection to the Member States is weakening. Differences in national legislation on creditor protection, defendable as they may be, are ultimately of a technical nature and create unnecessary and unjustifiable impediments. There are strong arguments, in other words, to adopt the same provisions for all transactions for the sake of simplicity, but while this may be attractive, it can lead to undesired delay. Amending the Directive at this point in time thus seems equally unfeasible. This stresses the need to make haste with at least some further harmonization of creditor protection rules related to the Third Directive.

    Full Text Available The article deals with the issues concerning the formation of the structure and properties of fine-grained concrete with organomineral additive produced through mechanochemical activation of thermal power plant fly ash together with superplasticizer. The additive is produced in a high-speed activator at the collision particles’ speed of about 80 m/s. The use of the additive in fine-grained concrete in the amounts of 0.5-1% increased the strength by 30-50% and reduced the size and volume of pores. The cement consumption in such concrete is close to the cement consumption in common concrete of equal resistance.

    Many coal preparation plants are forced to discard their fine coal because of the inability of existing technologies to reduce the moisture content of this product to an acceptable level. In an effort to overcome this problem, a new mechanical dewatering method has been developed that combines centrifugation with pressure filtration. The process, which may be referred to as hyperbaric centrifugation, is capable of producing a drier product than can be achieved using either filtration or centrifugation alone. The test data obtained from batch experiments show that the new method can reduce cake moisture to 10% or below for many fine coal product streams.

    In his earliest prismatic experiments (1665), the young Newton discovered the two border spectra (black-blue-turquoise/cyan-white; white-yellow-red-black). Newton chose to ignore them in his celebrated theory of light and colours (1672), as he took them to be derivative phenomena. In Goethe's Beyträge zur Optik (1791) and in his Farbenlehre (1808/10), they regained prominent attention. To the human eye, their colours appear much cleaner than the colours of Newton's spectra – particularly in t...

    Rivers, although inherently dynamic, have been chosen as political boundaries since the beginning of colonization for several reasons. Such divisions were chosen namely for their defensive capabilities and military benefits, and because they were often the first features mapped out by explorers. Furthermore, rivers were indisputable boundaries that did not require boundary pillars or people to guard them. However, it is important to understand the complexities of a river as a boundary. All rivers inevitably change over time through processes such as accretion, deposition, cut-off, or avulsion, rendering a political boundary subject to dispute. Depending upon the flow, size, and surrounding land, a river will migrate differently than others. As these natural features migrate one country loses land while another gains land leading to tension between legal rigidity and fluid dynamism. This in turn can manifest in social disruption due to cultural differences, political upheaval, or conflict risk as a result of scarce water resources. The purpose of this research is to assess the temporal and spatial variability of the political boundaries of Peru that follow rivers. Peru shares borders with Colombia, Brazil, Bolivia, Chile, and Ecuador. A large part of its northern border with Colombia follows the Putumayo River and later the Amazon River. Part of its eastern border with Brazil follows the Yavari River and later the Yaquirana River. These rivers are natural features used as political boundaries yet they differ in how each migrates. By means of a spatial and temporal analysis of satellite images it was possible to obtain erosion and deposition areas for the Putumayo River, the portion of the Amazon River that is part of the Peruvian boundary, the Yavari River, and the Yaquirana River. The erosion and deposition areas were related to land distribution among Peru, Colombia, and Brazil. By examining the Digital Elevation Model one can see how the altitude of the

  16. Use of recycled fine aggregate in concretes with durable requirements.

    Zega, Claudio Javier; Di Maio, Angel Antonio

    2011-11-01

    The use of construction waste materials as aggregates for concrete production is highly attractive compared to the use of non-renewable natural resources, promoting environmental protection and allowing the development of a new raw material. Several countries have recommendations for the use of recycled coarse aggregate in structural concrete, whereas the use of the fine fraction is limited because it may produce significant changes in some properties of concrete. However, during the last decade the use of recycled fine aggregates (RFA) has achieved a great international interest, mainly because of economic implications related to the shortage of natural sands suitable for the production of concrete, besides to allow an integral use of this type of waste. In this study, the durable behaviour of structural concretes made with different percentage of RFA (0%, 20%, and 30%) is evaluated. Different properties related to the durability of concretes such as absorption, sorptivity, water penetration under pressure, and carbonation are determined. In addition, the results of compressive strength, static modulus of elasticity and drying shrinkage are presented. The obtained results indicate that the recycled concretes have a suitable resistant and durable behaviour, according to the limits indicated by different international codes for structural concrete.

  17. Stimulation of border cell production in response to increased carbon dioxide levels.

    2000-01-01

    Field soil atmospheres have higher CO(2) and lower O(2) concentrations compared with ambient atmosphere, but little is known about the impact of such conditions on root exudation patterns. We used altered levels of CO(2) and O(2) relative to ambient conditions to examine the influence of the atmosphere on the production of root border cells by pea (Pisum sativum) root tips. During germination, atmospheres with high CO(2) and low O(2) inhibited root development and border cell separation in pea seedlings. Later in development, the same atmospheric composition stimulated border cell separation without significantly influencing root growth. Increased CO(2), not low O(2), was responsible for the observed stimulation of border cell number. High CO(2) apparently can override endogenous signals that regulate the number of border cells released from pea roots into the rhizosphere. The same conditions that stimulated border cell production in pea had no such effect in alfalfa (Medicago sativa).

    Alejandro Mungaray-Moctezuma

    2015-06-01

    Full Text Available The objective of this study is to analyze the mobility of consumption in the Mexicali-Imperial Valley border area. The study shows that the population in the Mexicali sections closer to border crossings generates the greatest amount of consumption dynamics with places located in Imperial Valley. Conversely, Imperial Valley sections that are more distant from the border concentrate a greater number of destination sites for these cross-border trips. It is concluded that a higher quality and more integrated road infrastructure allows the new consumption centers in Imperial Valley to be located farther away from the border and that the Mexicali population with visas can cross indiscriminately through any border crossing by taking longer journeys toward these centers.

    2000-11-01

    The United States and Mexico share an international boundary approximately 3000 km long. This border separates 2 nations with great differences in health status. The objective of this study was to assess morbidity due to infectious diseases in the US region bordering Mexico. The incidence between 1990 and 1998 of 22 nationally notifiable infectious diseases was compared between border and nonborder regions. Disease rates, reflected as rate ratios, were higher in the border region for botulism, brucellosis, diphtheria, hepatitis A, measles, mumps, rabies, rubella, salmonellosis, and shigellosis than in either of 2 nonborder comparison regions. These data indicate that incidence rates for a variety of infectious diseases of public health importance are significantly higher in the United States along the Mexican border than in nonborder regions. These results suggest that an inadequate public health infrastructure may contribute to excess morbidity due to infectious diseases in the border region.

  1. Effective flocculation of fine mineral suspensions using Moringa oleifera seeds

    Pickett, T.M. [Bureau of Mines, Reno, NV (United States)

    1995-12-31

    The purpose of this research was to investigate the feasibility of using Moringa oleifera seeds, or the active components of the seeds, in the clarification of waters containing suspended mineral fines. In comparative testing using a hematite suspension, the flocculating activity of Moringa oleifera seeds was better than alum. Twenty milligrams of seed powder was sufficient to clarify the hematite to near zero turbidity, while the same amount of alum had a minimal effect on turbidity. Extracts were prepared from the seeds in an attempt to separate the proteins. A crude protein extract was enriched by lowering the pH to 6.0. Only 0.08 mg/L of the enriched extract was required to flocculate a minusil suspension. Environmentally friendly protein flocculants could theoretically be produced and enhanced with recombinant DNA techniques as an alternative to chemical flocculants currently used in water treatment.

    Full Text Available Chronic obstructive pulmonary disease (COPD is a common airway disorder. In particular, acute exacerbations of COPD (AECOPD can significantly reduce pulmonary function. The majority of AECOPD episodes are attributed to infections, although environmental stress also plays a role. Increasing urbanization and associated air pollution, especially in developing countries, have been shown to contribute to COPD pathogenesis. Elevated levels of particulate matter (PM in polluted air are strongly correlated with the onset and development of various respiratory diseases. In this review, we have conducted an extensive literature search of recent studies of the role of PM2.5 (fine PM in AECOPD. PM2.5 leads to AECOPD via inflammation, oxidative stress, immune dysfunction, and altered airway epithelial structure and microbiome. Reducing PM2.5 levels is a viable approach to lower AECOPD incidence, attenuate COPD progression and decrease the associated healthcare burden.

    Full Text Available Purpose: The purpose of this paper is to describe the food landscape of Texas using the CDC’s Modified Retail Food Environment (mRFEI and to make comparisons by border/non-border. Methods: The Modified Retail Food Environment index (mRFEI (2008 is an index developed by the CDC that measures what percent of the total food vendors in a census track sell healthy food. The range of values is 0 (unhealthy areas with limited access to fruits and vegetables to (100—Healthy. These data were linked to 2010 US Census socioeconomic and ethnic concentration data. Spatial analysis and GIS techniques were applied to assess the differences between border and non-border regions. Variables of interest were mRFEI score, median income, total population, percent total population less than five years, median age, % receiving food stamps, % Hispanic, and % with a bachelor degree. Results: Findings from this study reveal that food environment in Texas tends to be characteristic of a “food desert”. Analysis also demonstrates differences by border/non-border location and percent of the population that is foreign born and by percent of families who receive food stamps. Conclusions: Identifying the relationship between socioeconomic disparity, ethnic concentration and mRFEI score could be a fundamental step in improving health in disadvantage communities, particularly those on the Texas-Mexico border.

    Due to recent frequent occurrence of fog and haze,the sources,components,migration and transformation of fine air particulate (PM2.5) have received increasing attention. However,little is known about microbial community associated with PM2.5. Here,we analyzed community composition and environmental sources of bacteria and eukaryotic microorganisms in PM2.5 using T-RFLP and clone library sequencing. Our results indicated that species richness of PM2.5 microbial communities assessed based on T-RFLP (i.e. TRF) were higher than those of clone libraries,implying that T-RFLP provide a sensitive and rapid approach to monitor airborne microbial community. Moreover,both of T-RFLP and clone library sequencing revealed highly diverse PM2.5 bacterial and eukaryotic microbial communities. BLAST analysis indicated that 2% of bacterial 16S rRNA gene and nearly half (42%) of eukaryotic 18S rRNA gene sequences from PM2.5 are distantly related to known sequences (<97% similarity). The results of RDP Classifier analysis indicated that PM2.5 bacterial community was mainly composed of Bacteroidetes,Actinobacteria,Firmicutes and Proteobacteria,accounting for 2.91%、10.68%、41.75%and 44.66%respectively,while PM2.5 eukaryotic microbial community were numerically dominated by Stramenopiles, Alveolata, Metazoa, Viridiplantae and Fungi, accounting for 5%、7%、15%、15%and 20%respectively. However, 39% of eukaryotic 18S rRNA gene sequences could not be assigned into any known eukaryotic phyla, suggesting that further studies are needed to shed light on eukaryotic airborne community. Taken together with the findings of a previous winter study investigating airborne microbial community in Xiamen, these results indicated that the airborne microbial community in Xiamen displays high temporal variation, and also airborne microbes may originate from various environments. Although Xiamen is a typical coastal city in China, freshwater, soils, sediments, wastewater and animal feces might be

    Fine root turnover is a major pathway for car-bon and nutrient cycling in forest ecosystems. However, to estimate fine root turnover, it is important to first understand the fine root dynamic processes associated with soil resource availability and climate factors. The objectives of this study were: (1) to examine patterns of fine root production and mortality in different seasons and soil depths in the Larix gmelinii and Fraxinus man-dshurica plantations, (2) to analyze the correlation of fine root production and mortality with environmental factors such as air temperature, precipitation, soil temperature and available nitrogen, and (3) to estimate fine root turn-over. We installed 36 Minirhizotron tubes in six mono-specific plots of each species in September 2003 in the Mao'ershan Experimental Forest Station. Minirhizotron sampling was conducted every two weeks from April 2004 to April 2005. We calculated the average fine root length, annual fine root length production and mortality using image data of Minirhizotrons, and estimated fine root turnover using three approaches. Results show that the average growth rate and mortality rate in L. melinii were markedly smaller than in F. mandshurica, and were high-est in the surface soil and lowest at the bottom among all the four soil layers. The annual fine root production and mortality in F. mandshurica were significantly higher than in L. gmelinii. The fine root production in spring and summer accounted for 41.7% and 39.7% of the total annual production in F. mandshurica and 24.0% and 51.2% in L. gmelinii. The majority of fine root mortality occurred in spring and summer for F. mandshurica and in summer and autumn for L. gmelinii. The turnover rate was 3.1 a-1 for L. gmelinii and 2.7 a-1 for F. mandshurica. Multiple regression analysis indicates that climate and soil resource factors together could explain 80% of the varia-tions of the fine root seasonal growth and 95% of the seasonal mortality. In conclusion, fine

    Full Text Available This paper presents an action-based fine-grained access control mechanism for structured documents. Firstly, we define a describing model for structured documents and analyze the application scenarios. The describing model could support the permission management on chapters, pages, sections, words, and pictures of structured documents. Secondly, based on the action-based access control (ABAC model, we propose a fine-grained control protocol for structured documents by introducing temporal state and environmental state. The protocol covering different stages from document creation, to permission specification and usage control are given by using the Z-notation. Finally, we give the implementation of our mechanism and make the comparisons between the existing methods and our mechanism. The result shows that our mechanism could provide the better solution of fine-grained access control for structured documents in complicated networks. Moreover, it is more flexible and practical.

    2016-11-01

    Prospects have never seemed better for a truly global approach to science to improve human health, with leaders of national initiatives laying out their vision of a worldwide network of related projects. An extensive literature addresses obstacles to global genomic data sharing, yet a series of public polls suggests that the scientific community may be overlooking a significant barrier: potential public resistance to data sharing across national borders. In several large United States surveys, university researchers in other countries were deemed the least acceptable group of data users, and a just-completed US survey found a marked increase in privacy and security concerns related to data access by non-US researchers. Furthermore, diminished support for sharing beyond national borders is not unique to the US, although the limited data from outside the US suggest variation across countries as well as demographic groups. Possible sources of resistance include apprehension about privacy and security protections. Strategies for building public support include making the affirmative case for global data sharing, addressing privacy, security, and other legitimate concerns, and investigating public concerns in greater depth.

    Full Text Available In recent years trans-boundary incursions from Petén, Guatemala into Belize’s Maya Mountain Massif (MMM have increased. The incursions are rapidly degrading cultural and natural resources in Belize’s protected areas. Given the local, regional and global importance of the MMM and the scarcity of deforestation data, our research team conducted a time series analysis 81 km by 12 km along the Belize-Guatemalan border adjacent to the protected areas of the MMM. Analysis drew on Landsat imagery from 1991 to 2014 to determine historic deforestation rates. The results indicate that the highest deforestation rates in the study area were −1.04% and −6.78% loss of forested area per year in 2012-2014 and 1995-1999 respectively. From 1991 to 2014, forested area decreased from 96.9 % to 85.72 % in Belize and 83.15 % to 31.52 % in Guatemala. During the study period, it was clear that deforestation rates fluctuated in Belize's MMM from one time-period to the next. This seems linked to either a decline in deforestation rates in Guatemala, the vertical expansion of deforestation in Guatemalan forested areas and monitoring. The results of this study urge action to reduce incursions and secure protected areas and remaining forest along the Belize-Guatemalan border.

  13. Golden Jubilee photos - The first cross-border Accelerator

    CERN Multimedia

    2004-01-01

    A few months after the signature of the agreement giving the go-ahead for the expansion of CERN into French territory (see Bulletin no.24/2004), work began on the Super Proton Synchrotron (SPS). Two years later, on 31 July 1974, the Robbins tunnel-boring machine excavating the SPS tunnel returned to its starting point (see photograph). It had excavated a tunnel with a circumference of 7 kilometres, at an average depth of 40 metres below the surface. The tunnel straddled the Franco-Swiss border, making the SPS the first cross-border accelerator. More than a thousand magnets were needed to equip the ring. The civil engineering and installation work was completed in record time after only four years. The SPS was equipped with a control system which was ahead of its time, consisting of 24 small control computers distributed in the tunnel and the control room and communicating by means of a high-rate data transmission system. The main control room housed only four consoles as opposed to the banks of electronic ...

  14. Bauhäusler on the Franco-Spanish Border

    2016-10-01

    Full Text Available This article focuses on the travels of Bauhaus masters and instructors and on the transport of Bauhaus products to Spain in 1929, when the Franco-Spanish border was still culturally permeable. Ludwig Mies van der Rohe and Marcel Breuer introduced their tubular-steel furniture in the Spanish market. Mies and Lilly Reich designed the interiors of all German industrial sections at the Barcelona International Exposition, where the Bauhaus sent objects from its carpentry, metal, and weaving workshops. Josef and Anni Albers traveled to see the exhibition and then went to meet Vassily Kandinsky and Paul Klee, who spent over a month on holiday in the Côte Basque. Albers captured their trip in photo collages, Kandinsky registered his impressions in snapshots, while Klee wrote abundant correspondence and produced drawings. Focusing on the itineraries the Bauhäusler followed, along with the means by which they expressed their travel impressions, this article reveals the effect of travel in their later design attitudes and work. Significant cultural transfers between Germany and Spain took place in a critical moment of European history, suggesting that further developments of these learning experiences might have materialized later on both sides of the border, possibly even reaching across the Atlantic.

  15. CROSS-BORDER COLLABORATION IN ENTREPRENEURIAL EDUCATION IN UNIVERSITIES

    2016-06-01

    Full Text Available The entrepreneurship, as an integral part of education, is now widely accepted worldwide. Entrepreneurial education is considered today as a holistic and inclusive process and not just a component of education in business. The activity of developing the entrepreneurial spirit organized on new principles must be seen by the universities as the foundation of successful fulfillment of university’s mission in contributing to social and economic development. This paper's main purpose is to identify a number of solutions on how they can ensure through cross-border cooperation the development of entrepreneurial skills within the universities through learning experiences contexts. In this regard, the paper proposes a model of entrepreneurial project which takes the form of simulated enterprise developed by the University of Pitesti, and a number of solutions for this project to be developed and implemented through cross-border cooperation, in accordance with the strategies and principles promoted by European Commission and European Parliament, which stresses the importance of developing through international cooperation of innovative methods that go beyond the traditional frame in which, currently, are formed the competencies and the educational process is performed. Thus, the proposed model can be expanded and implemented "in the mirror" and internationally by building partnerships between countries, universities and economic agents from those countries with real benefits for all parties involved through valuing the national specificities.

    In recent years trans-boundary incursions from Petén, Guatemala into Belize's Maya Mountain Massif (MMM) have increased. The incursions are rapidly degrading cultural and natural resources in Belize's protected areas. Given the local, regional and global importance of the MMM and the scarcity of deforestation data, our research team conducted a time series analysis 81 km by 12 km along the Belize-Guatemalan border adjacent to the protected areas of the MMM. Analysis drew on Landsat imagery from 1991 to 2014 to determine historic deforestation rates.

  17. Images crossing borders: image and workflow sharing on multiple levels.

    Ross, Peeter; Pohjonen, Hanna

    2011-04-01

    Digitalisation of medical data makes it possible to share images and workflows between related parties. In addition to linear data flow where healthcare professionals or patients are the information carriers, a new type of matrix of many-to-many connections is emerging. Implementation of shared workflow brings challenges of interoperability and legal clarity. Sharing images or workflows can be implemented on different levels with different challenges: inside the organisation, between organisations, across country borders, or between healthcare institutions and citizens. Interoperability issues vary according to the level of sharing and are either technical or semantic, including language. Legal uncertainty increases when crossing national borders. Teleradiology is regulated by multiple European Union (EU) directives and legal documents, which makes interpretation of the legal system complex. To achieve wider use of eHealth and teleradiology several strategic documents were published recently by the EU. Despite EU activities, responsibility for organising, providing and funding healthcare systems remains with the Member States. Therefore, the implementation of new solutions requires strong co-operation between radiologists, societies of radiology, healthcare administrators, politicians and relevant EU authorities. The aim of this article is to describe different dimensions of image and workflow sharing and to analyse legal acts concerning teleradiology in the EU.

  18. Border Collision Bifurcations in a Generalized Model of Population Dynamics

    Directory of Open Access Journals (Sweden)

    Lilia M. Ladino

    2016-01-01

    Full Text Available We analyze the dynamics of a generalized discrete time population model of a two-stage species with recruitment and capture. This generalization, which is inspired by other approaches and real data that one can find in literature, consists in considering no restriction for the value of the two key parameters appearing in the model, that is, the natural death rate and the mortality rate due to fishing activity. In the more general case the feasibility of the system has been preserved by posing opportune formulas for the piecewise map defining the model. The resulting two-dimensional nonlinear map is not smooth, though continuous, as its definition changes as any border is crossed in the phase plane. Hence, techniques from the mathematical theory of piecewise smooth dynamical systems must be applied to show that, due to the existence of borders, abrupt changes in the dynamic behavior of population sizes and multistability emerge. The main novelty of the present contribution with respect to the previous ones is that, while using real data, richer dynamics are produced, such as fluctuations and multistability. Such new evidences are of great interest in biology since new strategies to preserve the survival of the species can be suggested.

  19. Novel Cross-Border Approaches to Optimise Identification of Asymptomatic and Artemisinin-Resistant Plasmodium Infection in Mobile Populations Crossing Cambodian Borders.

    Directory of Open Access Journals (Sweden)

    Hannah M Edwards

    Full Text Available Human population movement across country borders presents a real challenge for malaria control and elimination efforts in Cambodia and its neighbouring countries. To quantify Plasmodium infection among the border-crossing population, including asymptomatic and artemisinin resistant (AR parasites, three official border crossing points, one from each of Cambodia's borders with Thailand, Laos and Vietnam, were selected for sampling.A total of 3206 participants (of 4110 approached were recruited as they crossed the border, tested for malaria and interviewed. By real-time polymerase chain reaction (RT-PCR, 5.4% of all screened individuals were found to harbour Plasmodium parasites. The proportion was highest at the Laos border (11.5%. Overall there were 97 P. vivax (55.7%, 55 P. falciparum (31.6%, two P. malariae (1.1% and 20 mixed infections (11.5%. Of identified infections, only 20% were febrile at the time of screening. Of the 24 P. falciparum samples where a further PCR was possible to assess AR, 15 (62.5% had mutations in the K13 propeller domain gene, all from participants at the Laos border point. Malaria rapid diagnostic test (RDT pLDH/HRP-2 identified a positivity rate of 3.2% overall and sensitivity compared to RT-PCR was very low (43.1%. Main individual risk factors for infection included sex, fever, being a forest-goer, poor knowledge of malaria prevention methods and previous malaria infection. Occupation, day of the week and time of crossing (morning vs. afternoon also appeared to play an important role in predicting positive cases.This study offers a novel approach to identify asymptomatic infections and monitor AR parasite flow among mobile and migrant populations crossing the borders. Similar screening activities are recommended to identify other hot borders and characterise potential hot spots of AR. Targeted "customised" interventions and surveillance activities should be implemented in these sites to accelerate elimination efforts

  20. Inhibition of growth and development of root border cells in wheat by Al.

    2003-03-01

    The production and development of border cells vary with genotype, and they are released in wheat at an earlier stage of root development than other species studied so far. No significant difference was observed in the maximum number of border cells between Al-tolerant (Atlas 66) and Al-sensitive (Scout 66) cultivars in the absence of Al treatment. Al seriously inhibited the production and release of border cells, resulting in clumping of border cells in Scout 66, but less clustering in Atlas 66. The number of border cells released from roots treated with Al is significantly less than that from roots grown without Al treatment. Al treatment induced the death of detached border cells in vitro and they were killed by a 20-h treatment with 25 micro m Al. No significant difference in survival percentage of detached border cells was observed between Atlas 66 and Scout 66, regardless of the presence or absence of Al. The removal of border cells from root tips of both Atlas 66 and Scout 66 enhanced the Al-induced inhibition of root elongation concomitant with increased Al accumulation in the root. These results suggest that border cells adhered to the root tips play a potential role in the protection of root from Al injury in wheat.

    Antecedentes: El aumento de la prevalencia de sobrepeso (SP) y la obesidad (OB) en niños mexicanos, hace necesario la valoración de los factores de riesgo ambientales. Objetivo: Valorar si existe asociación entre la disponibilidad de alimentos en el entorno de los niños y el consume de alimentos con el puntaje Z de IMC y la circunferencia de cintura (CC). Métodos: Participaron en el estudio 684, 264 padres, 22 maestros, el personal de cafetería de las escuelas, y vendedores ambulantes. Se valoró el peso, la estatura la CC, de niños de quinto año de educación básica. Se aplicaron a los padres, niños y maestros un cuestionario de frecuencia de consumo de alimentos, uno de actividad física y uno de hábitos alimentarios. Un inventario de alimentos se aplicó a los padres, al personal de la cafetería de la escuela, a los vendedores y a las tiendas cercanas a las escuelas. Resultados: La media de edad de los niños fue 10.5 años. 28% de los niños tenían SP, 26% OB, y 25% obesidad abdominal (OA). Se observó una correlación positiva entre el consumo de alimentos densamente energéticos (ADE), frutas, y verduras con la disponibilidad en casa y con el consumo semanal. También se observó una correlación entre el consumo de refrescos y otras ADE. El factor que más contribuía al consumo de alimentos fue la disponibilidad en casa y en la escuela (R2 = 0.11, p = 0.0001). Se observó una asociación positiva entre el tiempo que los niños ven televisión con el de sus padres. Por cada hora de aumento (de 0 a 7) de ver televisión al día, los niños tenían más posibilidades de tener SP o OB (OR=1.22 95% CI 1.02-1.45, p=0.026). Conclusión: La disponibilidad de ADE, de frutas y verduras en o fuera de casa o de la escuela, además de las horas de ver televisión estuvieron positivamente asociadas con la obesidad.

However, the picture is not clear, as the current waste management system (mainly incineration) is already working well, and in some cases it outperforms the biological treatment option.......The treatment of organic waste from households has gained significant interest in recent years. Each country in the EU and the rest of the world treat their organic waste in many different ways, and Denmark and Germany are no exemption in this regard. The treatment of household organic waste...... in these two countries has taken a very different turn in the last century.

    The preliminary results of the Finnish project `Carbon balance of peatlands and climate change` show that fine roots play an important role in carbon cycling on peat soils. After drainage the roots of mire species are gradually replaced by the roots of trees and other forest species. Pine fine root biomass reaches a maximum level by the time of crown closure, some 20 years after drainage on pine mire. The aim of this study is to compare the results of the sequential coring method and the ingrowth bag method used for estimating fine root production on three drained peatland sites of different fertility. The results are preliminary and continuation to the work done in the study Pine root production on drained peatlands, which is part of the Finnish project `Carbon cycling on peatlands and climate change`. In this study the fine root biomass was greater on the poor site than on the rich sites. Pine fine root production increased with the decrease in fertility. Root turnover and the production of field layer species were greater on the rich sites than on the poor site. The results suggested that the in growth bag method measured more root activity than the magnitude of production. More than two growing seasons would have been needed to balance the root dynamics in the in growth bags with the surrounding soil. That time would probably have been longer on the poor site than on the rich ones and longer for pine and field layer consisting of dwarf shrubs than for field layer consisting of sedge like species and birch.

    The Office of Environmental Management (EM) has been delegated the responsibility for the Department of Energy`s (DOE`s) cleanup of the nuclear weapons complex. The nature and magnitude of the waste management and environmental remediation problem requires the identification of technologies and scientific expertise from domestic and foreign sources. Within the United States, operational DOE facilities, as well as the decontamination and decommissioning of inactive facilities, have produced significant amounts of radioactive, hazardous, and mixed wastes. In order to ensure worker safety and the protection of the public, DOE must: (1) assess, remediate, and monitor sites and facilities; (2) store, treat, and dispose of wastes from past and current operations; and (3) develop and implement innovative technologies for environmental restoration and waste management. The EM directive necessitates looking beyond domestic capabilities to technological solutions found outside US borders. Following the collapse of the Soviet regime, formerly restricted elite Soviet scientific expertise became available to the West. EM has established a cooperative technology development program with Russian scientific institutes that meets domestic cleanup objectives by: (1) identifying and accessing Russian EM-related technologies, thereby leveraging investments and providing cost-savings; (2) improving access to technical information, scientific expertise, and technologies applicable to EM needs; and (3) increasing US private sector opportunities in Russian in EM-related areas.

    2016-11-01

    Recent advances in statistical downscaling have allowed the reconstruction of temperatures for the complete 1948-2011 period in a spatial resolution of 90 m and without gaps for the Valencian Community (Spain) and bordering areas. It presently enables analyses in this region, which allows the determination of recent temperature changes at subregional and local scales. The present work focuses on obtaining the thermicity index according to Rivas-Martínez, a well-known indicator of different thermotypes associated with bioclimatic horizons. The change in this index, which has happened in the region between 1948 and 2011, was calculated by generating fine-scale maps of the potential extension of different thermotypes. The results show a greater regression for the thermotypes in a finicolous position, e.g. Orotemperate, Supratemperate and Supramediterranean horizons, which herein indicate greater potential vulnerability in climate change. In the absence of, and given the need for, such fine-scale information, this work should be useful for specialized researchers to spatially limit the potentially most vulnerable biotopes to climate change.

    The accumulation of fine-grained sediments impairs the structure and function of streams, so removing fine sediments may be required to achieve restoration objectives. There has been little work on methods of removing excess sediment or on the efficacy of the methods. We used a 4-year before-after-control-impact design in southeastern Idaho streams to test a fine sediment removal system (FSRS) manufactured by Streamside Environmental LLC. The FSRS agitates fine sediment in the substrate with clean pump water and then vacuums the sediment out of the stream with a second pump. Our objectives were: 1) to test if the FSRS can selectively remove fine sediment; 2) to monitor the bio-physical responses in FSRS treated and downstream waters; and 3) to compare the bio-physical responses to the FSRS in spring-fed and snowmelt driven stream reaches. The FSRS removed ~ 14 metric tons of sediment from the two treated reaches. More than 90% of this sediment was < 2 mm, indicating that the FSRS selected for fine sediment in both stream types. Sustained effects of removing this sediment were confined to substrate improvements in treated reaches. Embeddedness in the spring-fed reach decreased and subsurface grain size in spring-fed and snowmelt driven reaches increased. We did not detect any sustained invertebrate or fish responses in treated reaches or any detrimental bio-physical responses in downstream waters. These results indicate that the FSRS reduced fine sediment levels but sediment removal did not reverse the impacts of sediment accumulation to stream biota within our monitoring time frame.

    2013-01-01

    The boundary between the United States and Mexico was created for convenient expediency through political debate and agreements (fig. 1–1). With the exception of the eastern segment of the border, which follows the course of the Rio Grande (known as the Rio Bravo in Mexico), the defining of this border was based on political decisions that had little concern for ecosystems, geologic features, or water—all of which span that imaginary line. However, the location of the border has had a remarkable effect on the biologic and physical systems in the border region and, in turn, has had a growing influence on what we now see as 21st century socioeconomic and environmental priorities. Because of the complex interactions of the human, ecological, political, and economic exigencies associated with this area, the status of the United States–Mexican border region, known as the Borderlands, has become an ever-present concern for most American citizens and for Mexican and United States Federal, State, and local governments.

  14. Flow "Fine" Synthesis: High Yielding and Selective Organic Synthesis by Flow Methods.

    2016-02-18

    The concept of flow "fine" synthesis, that is, high yielding and selective organic synthesis by flow methods, is described. Some examples of flow "fine" synthesis of natural products and APIs are discussed. Flow methods have several advantages over batch methods in terms of environmental compatibility, efficiency, and safety. However, synthesis by flow methods is more difficult than synthesis by batch methods. Indeed, it has been considered that synthesis by flow methods can be applicable for the production of simple gasses but that it is difficult to apply to the synthesis of complex molecules such as natural products and APIs. Therefore, organic synthesis of such complex molecules has been conducted by batch methods. On the other hand, syntheses and reactions that attain high yields and high selectivities by flow methods are increasingly reported. Flow methods are leading candidates for the next generation of manufacturing methods that can mitigate environmental concerns toward sustainable society.

    Cross-border ethnic marriage is a special form of marriage that is found in border are-as.Although there is a historical basis and it is sanctioned morally, it is characterized by loose u-nions with no legal certification.This eventually has impacts,either positive or negative,on social man-agement and social stability in the frontier region. In the areas along the long border of China, the phenomenon of cross-border ethnic marriage does not lack written documentation,and appears in va-rious kinds of media.However,in terms of the cur-rent focus of domestic academic circles, the phe-nomenon of cross-border ethnic marriage in the Si-no-Vietnam border area is of particular concern. Thus,this area has become one with typical case studies of cross-border ethnic marriage in China's border areas.Cross-border ethnic marriages among the frontier people who live in the Sino-Vietnam border area is a historical phenomenon.However,it was not until after the founding of New China (1949) that cases of cross-border ethnic marriages were systematically registered,and the data became more accurate.However, because of the mobility and hidden nature of the people involved with cross-border marriages,it makes the statistical data in the China-Vietnam border area less reliable.In-stead of having specific data,we can only have es-timates.

    The presentation will demonstrate how through alternative methods of digital print production the Centre for Fine Print Research (CFPR) is developing methodologies for digital printing that attempt to move beyond standard reproductive print methods. Profiling is used for input and output hardware, along with bespoke profiling for fine art printmaking papers. Examples of artist's work, and examples from the Perpetual Portfolio are included - an artist in residence scheme for selected artists wanting to work at the Centre and to make a large-format digital print. Colour is an important issue: colour fidelity, colour density on paper, colour that can be achieved through multiple-pass printing. Research is also underway to test colour shortfalls in the current inkjet ink range, and to extend colour through the use of traditional printing inks.

The neutralized (pH adjusted to 7.0) leachate was found to inhibit the growth of Escherichia coli (ATCC 259922) in a minimial mineral salts glucose medium; however, the inhibition was somewhat less than that caused by neutralized salicylic acid alone. The presence of lunar fines in the minimal medium was highly stimulatory to growth of E. coli following an early inhibitory response. The bacterium survived less well in the lunar leachate than in distilled water, no doubt because of the salicylate. It was concluded that the sample of lunar soil tested has nutritional value to E. coli and that certain products of fermentation helped to solubilize the lunar soil.

    The Freight Shuttle System (FSS) is designed to provide freight transportation services between those short and intermediate distance locations (within 600 miles) that are currently handling large volumes of freight traffic. Much like trucks, the FSS's transporters are autonomous: each transporter has its own propulsion and travels independently of other transporters. Inspired by railroads, each FSS transporter has steel wheels operating on a steel running surface and can carry either a standardsize freight container or an over-the-road truck trailer. However, unlike either rail or trucks, the FSS runs on an elevated, dedicated guideway to avoid the interference of other transportation systems. The objective of this report is to examine the potential viability for an alternative transportation system for trailers and containers in a multi-national, cross-border setting. The El Paso-Ciudad Juarez region serves as the environment of this analysis.

    that were conducted amongst Danish firms, our empirical evidence supports that CBM&A motives are based on Rationality Hypothesis, including Synergy Theory, Resource Dependence Theory, and Resource-based View. Besides, overconfidence and imitation sometimes play a role in the firms’ decision-making process......This study addresses two questions based on Danish firms’ practices: first, what are motives for cross-border mergers and acquisitions (CBM&As)? Second, how the external and internal factors influence the firms’ decisions? Based on the literature review, survey questionnaire and multiple-case study......, and acquiring technical knowledge & expertise are the top five motives for Danish firms. In addition, we found the nature of the firms’ businesses mainly determines their motives for conducting CBM&As. They focus on their core businesses rather than diversification, and horizontal CBM&As....

    One of the world’s leading problems in the field of national security is protection of borders and borderlands. This book addresses multiple issues on advanced innovative methods of multi-level control of both ground (UGVs) and aerial drones (UAVs). Those objects combined with innovative algorithms become autonomous objects capable of patrolling chosen borderland areas by themselves and automatically inform the operator of the system about potential place of detection of a specific incident. This is achieved by using sophisticated methods of generation of non-collision trajectory for those types of objects and enabling automatic integration of both ground and aerial unmanned vehicles. The topics included in this book also cover presentation of complete information and communication technology (ICT) systems capable of control, observation and detection of various types of incidents and threats. This book is a valuable source of information for constructors and developers of such solutions for uniformed servi...
