    Full Text Available Concrete is known as a porous building material, this can causes materials outside the concrete mass infiltrate into the concrete. Concrete structures constructed around the beach/seashore tend to have deterioration problems due to salt attack. This paper discusses models to predict the service life of concrete structure based on the deterioration problems. The service life of concrete structure is divided into three periods. Period I is time needed by Cl−ion to infiltrate into concrete up to the surface of the reinforcement, period II is time needed by corrosion products to fill the transition zone pores, and period III is deterioration time. The value of parameters used in the proposed equations is derived from the result of experiments. Finally, the proposed equations were evaluated by the relationship between variations of depth of concrete cover, water cement ratio (W/C and distance of structure from shore line with service life. It could be concluded that the results of the prediction is satisfactory. Abstract in Bahasa Indonesia : Beton dikenal sebagai bahan bangunan yang berpori. Sifat ini menyebabkan senyawa dari luar dapat berinfiltrasi ke dalam beton. Bangunan beton yang dibangun di sekitar daerah pantai/laut cenderung mengalami kerusakan akibat serangan garam klorida. Makalah ini mendiskusikan model untuk memprediksi waktu layan bangunan beton terhadap kerusakan akibat korosi baja tulangan. Waktu layan bangunan beton dibagi menjadi tiga periode. Periode I adalah waktu yang dibutuhkan oleh ion Cl− untuk melakukan infiltrasi sampai ke permukaan baja tulangan, Periode II adalah waktu yang dibutuhkan oleh senyawa hasil korosi untuk mengisi pori-pori yang ada di transition zone, dan Periode III adalah waktu kerusakan pada bangunan beton. Parameter-parameter yang digunakan dalam persamaan yang diusulkan ditentukan dari hasil pengukuran di laboratorium. Persamaan tersebut dievaluasi dalam hal hubungan antara variasi tebal selimut beton

    Full Text Available The use of structural concrete in Madura increases with the development of the island, however coarse and fine aggregates which are used, mostly come from Jawa. This research explores the possibility of using the coarse aggregates from Madura taken from Paterongan, Torjun, and Omben. Although it is shown that in general the coarse aggregates are physically the same with aggregates from Mojokerto or Pasuruan and pass SNI, ACI, ASTM, and BS, only aggregate from Torjun pass the flakiness requirements. The fineness modulus of the aggregates do not pass SNI but pass the BS requirement. Using the aggregates in 225kg/cm2 concrete strength mix design fail to reach the target strength. Aggregates from Paterongan and Omben are only recommended for lean concrete, but there is a possibility to use aggregates from Torjun for structural concrete, with betterment in grading. Abstract in Bahasa Indonesia : Pemakaian beton di pulau Madura meningkat seiring dengan perkembangan pulau Madura tetapi agregat kasar dan halus yang digunakan untuk pembuatan beton masih banyak didatangkan dari pulau Jawa. Untuk melihat kemungkinan penggunaan krikil Madura sebagai agregat kasar beton, telah dilakukan penelitian kekuatan terhadap kerikil Madura yang berasal dari Paterongan, Torjun, dan Omben. Meskipun secara umum dapat dikatakan sifat-sifat fisik kerikil tersebut mendekati sama dengan kerikil dari Mojokerto atau Pasuruan dan memenuhi syarat SNI, ACI, ASTM maupun BS, hanya krikil dari Torjun yang memenuhi syarat kepipihan. Modulus kehalusan kerikil tersebut juga tidak memenuhi syarat SNI walaupun masih memenuhi syarat BS. Penggunaan kerikil Paterongan, Torjun, dan Omben untuk mix disain 225 kg/cm2 ternyata di bawah target yang diharapkan, sehingga kerikil Paterongan dan Omben direkomendasi hanya untuk beton rabat, sedangkan kerikil dari Torjun kemungkinan masih bisa digunakan untuk beton struktur dengan perbaikan gradasi.

    Full Text Available Conduit (pipes in reinforced concrete columns is still used to date. ACI 318M-95 code limits the hole up to maximum 4% of the column cross sectional area. If the percentage is more than 4%, its effect toward its strength should be considered. But the Code does not mention the effect of the hollow cross section on the ductility. This study was done by testing hollow and solid columns with variation as follows: single stirrup ratio = 0.0184, double stirrup ratio = 0.0276, longitudinal steel ratio = 0.0252, concrete compression strength f’c = 26 MPa, column cross-section b = h = 200 mm, column length L = 1100 mm, hole-ratio (0%, 4.53%, 7.07%. Both ends of the column are loaded by constant axial compression load of 0.12f’cAg = 12,5 ton, lateral loads are applied at 1/3 and 2/3 points to produce moments. The observed variables are moment and curvature ductility. The result of the study shows that the 4% hollow column still has the same moment strength as the solid one. This experiment also indicates that its curvature ductility is within the range of 6.14    8.49, thus showing that the columns should be considered as limited ductile structure. If the hole-ratio is more than 4%, however, a decrease in the curvature ductility will be found. Abstract in Bahasa Indonesia : Sampai saat ini masih ditemui pemakaian konduit (pipa-pipa pada kolom beton bertulang, sehingga penampang kolom menjadi berlubang. Peraturan ACI 318M-95 membatasi besarnya lubang maksimum 4%, apabila persentase lubang  4%, maka besarnya lubang harus diperhitungkan terhadap pengaruh kekuatannya. Peraturan tersebut tidak menyinggung pengaruh lubang terhadap daktilitas kolom berlubang. Penelitian ini dilakukan dengan membuat benda uji kolom berlubang dan tak berlubang dengan variasi: rasio sengkang tunggal = 0,0184; rasio sengkang rangkap = 0,0276; rasio tulangan memanjang = 0,0252; f’c = 26 MPa, penampang kolom = b x h = 200 mm x 200 mm, panjang kolom = L = 1100 mm

  9. Fort St. Vrain performance

    International Nuclear Information System (INIS)

    Fort St. Vrain, on the system of Public Service Company of Colorado, is the only high temperature gas-cooled power reactor in the United States. This plant was designed by General Atomic Company and utilizes helium as the primary coolant. The core consists of triso-coated uranium and thorium fuel particles cast into cylinical rods within prismatic graphite blocks. The primary coolant system consists of the reactor, twelve steam generator modules, and four helium circulators contained within a prestressed concrete reactor vessel. The once-through steam generators provide high quality 1,000 deg. F, 2,400 psi main steam and 1,000 deg. F reheat steam to the main turbine. The plant has generated 3,334,000 MWH of electricity and has undergone 3 reactor refuelings. Many of the primary system components at Fort St. Vrain are proto-typical in nature and this plant has undergone an extensive and elaborate testing program. Difficulties primarily with the helium circulators and fuel element column movements particularly at high power levels have resulted in significant modifications. Power operation at 100% was achieved in late 1981 with a net thermal efficiency of nearly 39%. Excellent performance of the coated fuel particles has contributed to a full power circulating activity sixty times lower than the design with subsequent cleanliness throughout the plant. Except for 1985, when a combined total radiological exposure for all personnel reached 35 manrem due to the necessity to completely refurbish all of the control rod drive mechanisms, the average total combined exposure for each of the past five years was under 3 manrem. This exemplary radiological cleanliness has, with the exception of tritium, allowed Fort St. Vrain to consistently operate with noble gas airborne and liquid effluent releases more than an order of magnitude lower than the average for the U.S. nuclear power industry.

    Full Text Available The objective of this study was to evaluate the microbiological, physical and physico-chemical quality parameters of sous vide preparation of pen-reared tambaqui (Colossoma macropomum. To prepare the tambaqui sous vide, 200 g of fillet, 50 g of basil sauce (1:4 fish fillet:sauce ratio and 10 mL of 5% sodium lactate were used. The product was then vacuum-packaged, pasteurized at 65 ºC for 12.5 min and refrigerated. The presence of Salmonella spp., sulfite-reducing Clostridium and Listeria monocytogenes was not detected in the samples analyzed. The coliform count at 45 ºC and coagulase-positive staphylococci were below the limit (103 permitted by the law in vigor. Water retention capacity and chloride content analyses revealed that the tambaqui fillet differed significantly (P<0.05 from the sous vide because of the addition of basil sauce. The total volatile basic nitrogen (TVB-N and thiobarbituric acid reactive substances (TBARS content of the fillet and sous vide were below the limits established by the law, indicating good quality. The lightness (L* and yellow color (b* of the fillet and the sous vide did not differ significantly (P>0.05, but the red color (a* decreased in the sous vide, which is related to the addition of basil sauce. The chroma (C* and hue angle (ho differed significantly (P<0.05, and the fillet samples were lighter in color, whereas the sous vide was characterized by yellow color. The n-6/n-3 ratios found for the fillet and the sous vide are within the recommended values, which is important for human metabolism. The fillet and sous vide also had high calcium, zinc, magnesium and potassium concentrations. It is concluded that tambaqui sous vide is a good source of nutrients, rich in fatty acids and minerals essential for human health.

  1. Etude du comportement sous charges laterales des ossatures de beton arme avec murs de remplissage de maconnerie, construites avant les annees 1960

    Science.gov (United States)

    Lefebvre, Karine

    Reinforced concrete structures with unreinforced masonry infills (BMR) are considered vulnerable to earthquakes. Under seismic actions, infills could fail (causing injuries or death) and cause damages to columns. In Quebec and Canada, most of BMR structures have been constructed prior to the introduction of modern seismic design codes raising question on the contribution of the infill to the structure lateral resistance. The aim of this thesis is to improve modelling technique of BMR structures built in Quebec between 1915 and 1960. This type of structures is found in hospitals or schools buildings, which must comply with some post-earthquake functionality requirements. They could also be residential or office buildings. Actually, practicing engineers usually calculate seismic capacity of BMR structures without considering the infill's structural contribution to the lateral resistance. Yet, this contribution should not be omitted. The first part of the thesis investigates the construction techniques and material properties of the old BMR structures in the Province. The results are the material properties (concrete, reinforcing steel, brick, terra cotta tile, and mortar) and the characteristics of the assemblies (wall section, reinforcement details…). The second part of the thesis presents the results of series of parametric analyses to identify among modelling and geometric parameters, which ones are the most influent on the lateral load response (rigidity, fundamental period, normal modes). Linear and modal analyses were performed. The most influent parameters identified are: number of storeys, number of bays, bay's width, soft storey, openings, upper storeys modelized (instead of being replaced by punctual loads) and the modelization technique of infills panels (strut or shell). Nonlinear static analyses have been performed to identify the most influent parameters to be considered for evaluating the lateral resistance, the capacity (load / displacement) and the yielding sequence (beam versus columns versus infills). The identified parameters are the presence of the infills, the openings and the geometric characteristics of the models (number of storeys and number of bays). One important contribution of this work is the development of an equivalent strut model to represent the action of the infill. The model could be easily implemented in standard analysis software. A central axial hinge reproducing the nonlinear behaviour of the masonry is added to the strut element. This model is a hybridization of existing proposals (FEMA and others) with added innovations by the author. It has been validated with experimental and numerical analyses results from literature. An important conclusion of this thesis is that the contribution of infills to lateral load resisting capacities of BMR structures should be considered for structure of more than one storey. Infills can add up to 51 % to bare frame capacity. The National building code requires that the lateral resistance of existing buildings must be at least 60 % of the equivalent static seismic force (V2005). It is concluded that one storey BMR buildings have a sufficient resistance, while three-storeys structures exhibit plastic deformations for loads under 0,6* V2005.

    Laras, A

    1999-07-01

    The reactor building of a nuclear power plant must ensure its protection and tightness functions in the most unfavorable conditions of operation, like during an earthquake. The method currently used for the seismic calculation of buildings consists in the determination of the maximum probable response for each of the Eigen-modes of the structure. The aim of this study is to develop a non-linear calculation model for the estimation of the response of reinforced concrete structures. The structure under study is a beam embedded in its base and having a 2 tons load on its top. The structure is excited by a seismic or pulsed signal. In a first step, the global behavioural model of reinforced concrete is determined using the concrete and steel armatures behaviour laws. Then, a computer code is developed for the calculation of the seismic excitation of the beam. The beam is assimilated to a non-linear oscillator. A damaging parameter has been introduced in the model to take into account the damping observed experimentally. Finally, the excitation signal is analyzed in order to determine the parameter responsible for the significant increase of the structure response. (J.S.)

    Le diaphragme sous aortique se caractérise par une certaine latence clinique et une faible morbi-mortalité. La chirurgie reste le traitement de choix malgré un réel risque de récurrence à long terme. Nous rapportons 18 patients opérés entre Avril 1994 et Mars 2011 pour diaphragme sous aortique d’âge moyen de 18,1±9,7 ans avec 11 patients de sexe masculin. Le diaphragme était de nature fibreuse chez 13 patients et fibro-musculaire chez 5 patients. Tous les patients ont été opérés par résection de diaphragme associée à une myectomie, une plastie aortique, une fermeture de communication interventriculaire et une ligature de canal artériel perméable respectivement chez 3, 3, 2 et 2 patients. La Mortalité opératoire était nulle et sans aucun cas de trouble de conduction postopératoire. Le suivi a duré en moyenne 44,3±36,8 mois sans aucun décès tardif. Deux patients ont présenté une récidive de diaphragme qui a nécessité une réopération avec bonne évolution. La tendance actuelle dans la chirurgie du diaphragme se fait vers des interventions précoces et des résections plus extensives. Cependant, le risque de récidive impose une surveillance échographique systématique et rapprochée. PMID:27516830

    The great archipelago in Indonesia with its wealthy and various nature, the products and commodities of tropic agriculture and the rich soil, was through the centuries a region of interest for other countries all over the world. For several reasons some of these countries came to Indonesia to establish their existence and tried to monopolize the trading. These countries such as the Portuguese, the Spanish, the Dutch and the British built strengthened trade stations which later became forts all over Indonesia to defend their interest. The archipelago of Indonesia possesses a great number of fortification-works as legacies of native rulers and those which were built by European trading companies and later became colonial powers in the 16th to the 19th centuries. These legacies include those specific structures built as a defence system during pre and within the period of World War II. These fortresses are nowadaysvaluable subjects, because they might be considered as shared heritage among these countries and Indonesia. It's important to develop a vision to preserve these particular subjects of heritage, because they are an interesting part of the Indonesian history and its cultural treasures. The Government of the Republic of Indonesia has national program to compile a comprehensive documentation of the existing condition of these various types of forts as cultural heritage. The result of the 3 years project was a comprehensive 442 forts database in Indonesia, which will be very valuable to the implementation of legal protection, preservation matters and adaptive re-use in the future.

    Full Text Available Recently, displacement-based seismic design concept is being developed. According to this concept, structures are designed based on a certain displacement target. This paper presents the application of the displacement-based design concept to reinforced concrete bridge piers of 3, 5, 7, 9 11,and 13 m height. The design results are then analyzed by inelastic time history analysis using Ruaumoko computer program. The results of inelastic time history analysis show that for bridge piers with height 7 m or more, the actual drifts relatively fit the design drifts, while for the 3m and the 5m height piers, the actual drifts are significantly less than the design drifts. Abstract in Bahasa Indonesia : Akhir-akhir ini sedang dikembangkan metode perencanaan seismik struktur dengan konsep berbasis perpindahan. Dengan konsep ini struktur direncanakan berdasarkan target perpindahan yang dikehendaki. Tulisan ini membahas aplikasi konsep berbasis perpindahan pada perencanaan struktur pilar jembatan beton bertulang dengan ketinggian 3, 5, 7, 9, 11, dan 13 m. Hasil perencanaan kemudian dianalisis dengan analisis inelastik riwayat waktu dengan menggunakan program komputer Ruaumoko. Hasil analisis inelastik riwayat waktu menunjukkan bahwa untuk pilar dengan ketinggian 7m atau lebih drift yang terjadi cukup sesuai dengan drift yang direncanakan, sedangkan untuk pilar dengan ketinggian 3m dan 5m drift yang terjadi relatif jauh lebih kecil daripada drift yang direncanakan.

  17. Fort St. Vrain decommissioning project

    International Nuclear Information System (INIS)

    Public Service Company of Colorado (PSCo), owner of the Fort St. Vrain nuclear generating station, achieved its final decommissioning goal on August 5, 1997 when the Nuclear Regulatory Commission terminated the Part 50 reactor license. PSCo pioneered and completed the world's first successful decommissioning of a commercial nuclear power plant after many years of operation. In August 1989, PSCo decided to permanently shutdown the reactor and proceed with its decommissioning. The decision to proceed with early dismantlement as the appropriate decommissioning method proved wise for all stake holders - present and future - by mitigating potential environmental impacts and reducing financial risks to company shareholders, customers, employees, neighboring communities and regulators. We believe that PSCo's decommissioning process set an exemplary standard for the world's nuclear industry and provided leadership, innovation, advancement and distinguished contributions to other decommissioning efforts throughout the world.

  7. Fort Hood solar energy project

    Energy Technology Data Exchange (ETDEWEB)

    1980-07-30

    During the period April 1975 to March 1978, the American Technological University (ATU) of Killeen, Texas, was awarded several follow-on contracts by the Division of Solar Energy (DSE), Energy Research and Development Administration (ERDA), which subsequently became the Division of Solar Technology (DST), Department of Energy (DOE). The contracts were to design a solar total energy system for use at Fort Hood, Texas. A review encompassing the period of the project from January 1975 to March 1978, was conducted by the Office of Inspector General (IG), DOE. The review examined both the management of the project by ATU and ERDA personnel and the award and administration by ERDA of the contracts to ATU for support of the project. The IG review found that: (1) there was a lack of continuity in the management of the project by both ATU and ERDA; (2) ERDA failed to maintain control of the project and failed to issue specific project direction to ATU; (3) ERDA failed to follow existing procurement regulations for the review and acceptance of unsolicited proposals from ATU; (4) the ERDA Headquarters program Manager and the Contract Administrator for the conceptual design phase of the project had failed to ensure that all the tasks which had been funded were performed by ATU; and (5) the decision by the Director, ERDA/DSE, to award successive contracts to ATU was questionable in view of ATU's performance on the project.

  13. Fort St. Vrain decommissioning experience

    International Nuclear Information System (INIS)

    Nuclear plant decommissioning represents a significant expenditure of time and resources for nuclear utilities. Public Service Company of Colorado (PSC) is in the process of completing the decommissioning of the Fort St. Vrain (FSV) Nuclear Station, the first large-scale commercial nuclear plant to be decommissioned under the U.S. Nuclear Regulatory Commission's (NRC's) 1988 decommissioning rule. PSC's experience has included dispositioning spent fuel, choosing a decommissioning alternative, and actively decommissioning the plant from dismantlement and decontamination through final survey. When the plant was prematurely shut down in August 1989, PSC's initial task was to find a storage location for FSV's spent fuel. PSC had a contract with the U.S. Department of Energy (DOE) to ship FSV spent fuel to the Idaho National Engineering Laboratory (INEL), and all previously removed spent fuel had been shipped there. However, Idaho legally blocked further FSV spent-fuel shipments to INEL, and PSC decided to license and build an on-site, passively cooled independent spent-fuel storage installation (ISFSI). By June 1992, all FSV spent fuel was transferred from the reactor building to the ISFSI. PSC has been able to use low-level radioactive waste (LLWR) disposal facilities in the Northwest Compact, and disposal costs are within estimates. Industrial and radiological safety have been emphasized throughout the project, and performance in these areas has been outstanding. PSC has obtained NRC Aprilproval of a final survey plan that allows for many of the plant's components and systems to remain in place, and final survey activities are nearing completion. PSC is in the process of repowering the facility with natural gas-fired combustion turbines and heat recovery boilers. The first combustion turbine was placed in service Ap 30, 1996

  3. Fort St. Vrain operations and future

    International Nuclear Information System (INIS)

    June 1989 resulted in the highest electric generation month in the history of the Fort St. Vrain plant. This culminated an excellent operating period involving the first half of 1988. The plant was then shutdown in July on a scheduled outage to make repairs in the main steam drive section of all of the helium circulators. This outage was significantly extended due to problems with moisture ingress into the primary coolant felt to be primarily from the core support floor section of the liner cooling system. 1989 also marks the 10th Anniversary of Fort St. Vrain as a commercial nuclear power plant. Electrical generation from this plant throughout this period has not been good, generally because of the prototypical nature of key plant components, primarily the helium circulators. Also, throughout this period there has been substantial increase in operations, maintenance, and fuel costs which could not be offset by the sale of electricity from the plant. This led to the decision to shutdown Fort St. Vrain permanently on or before June 30, 1990. The lessons learned and operational experiences from Fort St. Vrain have been substantial for the development of the Gas-Cooled Reactor Program and in achieving a safe, commercially viable plant design for the MHTGR. Superb fuel performance has not only provided a radiologically clean plant, but has achieved significant safety attributes in the licensing of the MHTGR. Equipment performance for Fort St. Vrain on key components and systems such as the steam generators, purification system control rod drives, and many others has been factored into the design of the MHTGR. Additional benefits are anticipated as the plant completes its operating phase and goes through defueling and decommissioning. As primary system components become available and are physically evaluated, further valuable data will be secured for the benefit of the MHTGR. (author)

    Science.gov (United States)

    Stohlgren, Tom

    2004-01-01

    Invasive, non-native species of plants, animals, and disease organisms adversely affect the ecosystems they enter. Like "biological wildfires," they can quickly spread, and they affect nearly all terrestrial and aquatic ecosystems. Invasive species have become the greatest environmental challenge of the 21st century in terms of economic, environmental, and human health costs, with an estimated impact in the U.S. of over $138 billion per year. Managers of Department of the Interior and other public and private lands and waters rank invasive species as their top resource management problem. The Invasive Species Science Branch of the Fort Collins Science Center (FORT) provides research and technical assistance relating to invasive species management concerns, including understanding how these species are introduced, identifying areas vulnerable to invasion, forecasting invasions, and developing control methods. To disseminate this information, FORT scientists are developing the Invasive Species Information Node of the National Biological Information Infrastructure (NBII), a comprehensive, Web-accessible database of invasive plant and animal species and disease agents. From these data, and in partnership with Colorado State University, the National Aeronautic Space Administration (NASA), and others, FORT scientists are constructing models to understand and predict invasive species behavior for more effective management. FORT is also the administrative home of the National Institute of Invasive Species Science, a growing consortium of partnerships between government and private organizations established by the U.S. Geological Survey (USGS) and its many cooperators. The Institute was formed to develop cooperative approaches for invasive species science that meet the urgent needs of land managers and the public. Its mission is to work with others to coordinate data and research from many sources to predict and reduce the effects of harmful nonnative plants, animals, and

  10. Fort St. Vrain circulator operating experience

    International Nuclear Information System (INIS)

    Fort St. Vrain, on the system of Public Service Company of Colorado, is the only high-temperature gas-cooled power reactor in the United States. Four helium circulators are utilized in this plant to transfer heat from the reactor to the steam generators. These unique machines have a single stage axial flow helium compressor driven by a single stage steam turbine. A single stage water driven (pelton wheel) turbine is the back-up drive utilizing either feed water, condensate, or fire water as the driving fluid. Developmental testing of the circulators was accomplished prior to installation into Fort St. Vrain. A combined machine operating history of approximately 250,000 hours has shown these machines to be of conservative design and proven mechanical integrity. However, many problems have been encountered in operating the complex auxiliaries which are necessary for successful circulator and plant operation. It has been 15 years since initial installation of the circulators occurred at Fort St. Vrain. During this time, a number of significant issues had to be resolved dealing specifically with machine performance. These events include cavitation damage of the pelton wheels during the initial plant hot functional testing, cracks in the water turbine buckets and cervic coupling, static shutdown seal bellows failure, and, most recently, degradation of components within the steam drive assembly. Unreliable operation particularly with the circulator auxiliaries has been a focus of attention by Public Service Company of Colorado. Actions to replace or significantly modify the existing circulators and their auxiliaries are currently awaiting decisions concerning the long-term future of the Fort St. Vrain plant.

    The bond behaviour of textiles embedded in concrete and consisting of multi filament yarns (rovings) differs from that of homogeneous materials, such as steel. Test results published in literature as well as own investigations revealed that, for textile reinforced concrete, it has to be distinguished between external and internal bond of the fibres (filaments). The outer filaments which have contact to the cement matrix show a good bonding performance. In contrast to this, the inner filaments (core filaments) of a roving transfer forces only by friction, from which a less bonding to the surrounding matrix follows. In order to confirm such a bonding model, strain and slip measurements at single filaments are necessary in pull-out-samples. However, such measurements are not possible with in structural engineering usually used strain gages. Therefore, strain portions of outer and inner filaments as well as in the cement matrix of selected samples are measured by using flexible Fabry-Perot fibre interferometer sensors. (orig.)

    The prediction of delayed strains is of crucial importance for durability and long-term serviceability of concrete structures (bridges, containment vessels of nuclear power plants, etc.). Indeed, creep and shrinkage cause cracking, losses of pre-stress and redistribution of stresses, and also, rarely, the ruin of the structure. The objective of this work is to develop numerical tools, able to predict the long-term behavior of concrete structures. Thus, a new hydro mechanical model is developed, including the description of drying, shrinkage, creep and cracking phenomena for concrete as a non-saturated porous medium. The modeling of drying shrinkage is based on an unified approach of creep and shrinkage. Basic and drying creep models are based on relevant chemo-physical mechanisms, which occur at different scales of the cement paste. The basic creep is explicitly related to the micro-diffusion of the adsorbed water between inter-hydrates and intra-hydrates and the capillary pores, and the sliding of the C-S-H gel at the nano-porosity level. The drying creep is induced by the micro-diffusion of the adsorbed water at different scales of the porosity, under the simultaneous effects of drying and mechanical loadings. Drying shrinkage is, therefore, assumed to result from the elastic and delayed response of the solid skeleton, submitted to both capillary and disjoining pressures. Furthermore, the cracking behavior of concrete is described by an orthotropic elastoplastic damage model. The coupling between all these phenomena is performed by using effective stresses which account for both external applied stresses and pore pressures. This model has been incorporated into a finite element code. The analysis of the long-term behavior is also performed on concrete specimens and prestressed concrete structures submitted to simultaneous drying and mechanical loadings. (author)

  19. Operational testing highlights of Fort St. Vrain

    International Nuclear Information System (INIS)

    The 330-MW(e) Fort St. Vrain reactor, built by General Atomic for the Public Service Company of Colorado, is the first commercial High-Temperature Gas-Cooled Reactor (HTGR) employing the multi-hole block-type fuel element design. Bringing the Fort St. Vrain HTGR to commercial operation is one of the major ongoing efforts at General Atomic. The Fort St. Vrain programme has progressed through construction, pre-operational testing and checkout of innumerable systems, fuel loading, initial criticality, and operational testing at power levels up to 2% rated power. Thus far, all major plant systems including the PCRV, circulators, and steam generators have demonstrated their performance adequacy during the tests performed to date. Extensive tests on the reactor core at zero power and up to 2% power have demonstrated the accuracy in the design predictions of core characteristics; measured nuclear parameters such as initial criticality, control system worths, neutron flux distributions, and temperature coefficients agreed extremely well with precalculated values. Gaseous fission product release measurements to date confirmed the extensive analytical estimates. Significant unforeseen schedule delays have centred around the control rod drives, circulator service water systems and problems arising from the introduction of large quantities of water into the primary system as well as from meeting all licensing requirements for electrical cable separation and seismic restraint systems for steam lines. To date, all tests necessary before the rise-to-full-power have been completed, and the rise-to-power programme is expected to be resumed again in the fall of 1975. The schedule delays which have arisen from mechanical, electrical, or operational problems had to be expected from the startup of a first-of-a-kind plant, but none of the problems has indicated any deficiencies with the unique advantages of the HTGR concept.

    International Nuclear Information System (INIS)

    A European coordinated research program for the study of hot-dry-rock systems is in progress at Soultz-sous-Forets (Alsace, France). The aim of this project is the extraction of heat from the granite batholiths distributed along the Rhine graben. The technique used involves important forced water circulations under relatively low-pressures using the natural geologic fractures network. The region concerned extends about 3000 km2 under both the French and the German territories. The program started in 1987 with preliminary scientific investigations followed by a feasibility study. In December 1995, two deep wells, GPK1 (3600 m) and GPK2 (3900 m) were available and equipped for hydraulic testing. Temperatures encountered can reach 168 C at 3800 m with a geothermal gradient exceeding 3.5 C/100 m below 3600 m. The tests performed have shown that the hydraulic performances of these wells can be considerably improved using a simple well stimulation technique. (J.S.). 1 fig

    Severe flooding occurred in northern Maine from April 28 to May 1, 2008, and damage was extensive in the town of Fort Kent (Lombard, 2010). Aroostook County was declared a Federal disaster area on May 9, 2008. The extent of flooding on both the Fish and St. John Rivers during this event showed that the current Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS) and Flood Insurance Rate Map (FIRM) (Federal Emergency Management Agency, 1979) were out of date. The U.S. Geological Survey (USGS) conducted a study to develop a flood inundation map library showing the areas and depths for a range of flood stages from bankfull to the flood of record for Fort Kent to complement an updated FIS (Federal Emergency Management Agency, in press). Hydrologic analyses that support the maps include computer models with and without the levee and with various depths of backwater on the Fish River. This fact sheet describes the methods used to develop the maps and describes how the maps can be accessed.

  5. Experience with the Fort St. Vrain reactor

    International Nuclear Information System (INIS)

    A brief description is given of the HTGR at Fort St. Vrain. Highlights of construction and preliminary testing are summarised. Details are given of preoperational physics tests, and the rise to power test programme is discussed. Preliminary low power and intermediate power tests have proved the design concept features and calculations and most of the components. Safe conditions following loss of coolant were confirmed. Release of radioactivity from the fuel was less than predicted up to 70% full power. Modifications and repairs caused delays and included, chiefly: Pelton wheel emergency cooling drives, helium circulator bearings, the pressure-regulating system for water lubricant in circulator bearings, liner cooling lines, removal of moisture from the vessel, electrical cable rerouting, helium seals around control rod drives, and a leak in one steam generator. Core temperature oscillation problems are being analyzed before passing the currently imposed 70% power level. Fort St. Vrain has demonstrated that the concept of a large HTGR system incorporating a prestressed concrete reactor vessel is sound. (author)

    Fort St. Vrain Nuclear Generating Station (FSV) is one of the first commercial reactors to be decommissioned under NRC's decommissioning rule. The defueling and decommissioning of this 330 MWe High Temperature Gas Cooled Reactor (HTGR) has involved many challenges for Public Service Company of Colorado (PSC) including defueling to an Independent Spent Fuel Storage Installation (ISFSI), establishing decommissioning funding, obtaining regulatory approvals, arranging for waste disposal, and managing a large fixed price decommissioning contract. In 1990, a team comprised of the Westinghouse Corporation and Morrison Knudsen Corporation, with the Scientific Ecology Group as a major subcontractor, was contracted by PSC to perform the decommissioning under a fixed price contract. Physical work activities began in August 1992. Currently, physical dismantlement activities are about 45% complete, the project is on schedule, and is within budget

  12. Operational experience at Fort St. Vrain

    International Nuclear Information System (INIS)

    The Fort St. Vrain (FSV) station, a 330-MW(e) single reheat steam cycle powered by a high-temperature gas-cooled reactor (HTGR), is the first HTGR to enter commercial operation. Designed and built by General Atomic Company (GA), the plant is owned and operated by Public Service Company of Colorado (PSC). Many unique design features have been incorporated into this reactor system, including high-pressure helium as the primary system coolant, a graphite-moderated prismatic block core design, fission-product-containing carbide coatings on both fissile and fertile fuel particles, steam-driven helium circulators turning on water bearings, and once-through steam generators. All of these systems are contained in a prestressed concrete reactor vessel (PCRV). Extensive testing has been conducted during the rise to power following first criticality early in 1974 to verify system design performance. During this period, the plant has operated at power levels up to 70% and produced over one billion kilowatt hours of electricity. In 1979, the first refueling was conducted in conjunction with an extensive in-core inspection, the addition of in-core instrumentation, and a planned removal of a circulator for inspection. Later in the year, a scheduled shutdown was undertaken for surveillance tests, insertion of core region constraint devices (RCDs), and other maintenance. Fort St. Vrain has encountered problems of the type that would be expected in a first-of-a-kind system. The plant is currently restricted to 70% of design power by the Nuclear Regulatory Commission (NRC) pending resolution of the core region gas outlet temperature fluctuation problem. Even so, the basic performance of the HTGR concept and all of the unique design features have been successfully demonstrated. The system has been characterized by low personnel radiation exposures, operational flexibility, and long time afforded for status evaluation and response. (author)

  2. SPace Radar Image of Fort Irwin, California

    Science.gov (United States)

    1994-01-01

    This image of Fort Irwin in California's Mojave Desert compares interferometric radar signatures topography -- data that were obtained by multiple imaging of the same region to produce three-dimensional elevation maps -- as it was obtained on October 7-8, 1994 by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar aboard the space shuttle Endeavour. Data were acquired using the L-band (24 centimeter wavelength) and C-band (6 centimeter wavelength). The image covers an area about 25 kilometers by 70 kilometers (15.5 miles by 43 miles). North is to the lower right of the image. The color contours shown are proportional to the topographic elevation. With a wavelength one-fourth that of the L-band, the results from the C-band cycle through the color contours four times faster for a given elevation change. Detailed comparisons of these multiple frequency data over different terrain types will provide insights in the future into wavelength-dependent effects of penetration and scattering on the topography measurement accuracy. Fort Irwin is an ideal site for such detailed digital elevation model comparisons because a number of high precision digital models of the area already exist from conventional measurements as well as from airborne interferometric SAR data. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human

    2016-02-01

    The Le Fort II osteotomy is a relatively rare operation. The posterior wall osteotomy of the maxillary sinus (MS) is often difficult for Le Fort III. We developed the transmaxillary sinus approach (TSA) for the Le Fort II osteotomy that cuts the posterior wall of the MS directly. This report illustrates this easy-to-use procedure for the Le Fort II osteotomy in syndromic craniosynostosis. This procedure was performed in an 18-year-old patient with Apert syndrome and a 15-year-old patient with Pfeiffer syndrome. The thin anterior walls of the MS were removed through an intraoral approach to look inside the MS. Then, the posterior walls were cut by chisel under direct vision using light. The other osteotomy was performed as usual. Distraction osteogenesis with internal and external devices was used in combination. The advantages of TSA are the direct posterior wall osteotomy of the MS with no down fracture and minimal invasiveness to the mucosa of the MS under direct vision. However, the disadvantage is that TSA becomes a blind procedure in a case with no MS or hypoplasia. We developed the TSA for the Le Fort II osteotomy, which could provide direct observation and perform the posterior wall osteotomy of the MS without down fracture. We believe that TSA is an effective surgical procedure for the Le Fort II osteotomy. PMID:27014548

  6. Fort St. Vrain hot functional test results

    International Nuclear Information System (INIS)

    A description is given of Fort St. Vrain hot functional tests performed to evaluate the initial nonnuclear performance of the primary coolant system and the associated effects on the various internal components of the reactor vessel and primary coolant system. The components included the twelve steam generator modules, the four helium circulators, the PCRV thermal barrier and liner coolant system, the helium purification system, and the primary and secondary closures at each of the PCRV penetrations. Additional objectives included analysis of the parallel operation of the four helium circulators and the performance of several circulator start/stop transients under various conditions of primary coolant temperature and pressure. Vibration and acoustical phenomena within the vessel were measured, recorded, and compared to theoretical analyses; a verification of reverse flow in the shutdown loop steam generator during one loop operation was performed; the PCRV was again observed for its structural response to internal pressure; and comparisons were made relative to data recorded during the initial pressure test completed in July 1971.

  7. Decommissioning progress at Fort St. Vrain

    International Nuclear Information System (INIS)

    Decommissioning of commercial nuclear power plants in the US has initiated with the current dismantling of the Fort St. Vrain Nuclear Generation Station in Colorado. Owned and operated by Public Service Company of Colorado (PSC), the unit was permanently shutdown in 1989. After a thorough evaluation by the utility of the DECON versus SAFSTOR options, the decision was made to proceed with decommissioning the power station for unrestricted release. In 1990 a team comprised of Westinghouse Electric Corporation and Morrison Knudsen Corporation was selected by PSC to perform the decommissioning on a fixed price, turnkey basis. The Westinghouse Team (WT) concept was based on an innovative approach for dismantling the Prestressed Concrete Reactor Vessel (PCRV) by flooding it and performing most operations using underwater tooling. This approach provided the maximum shielding and contamination control along with an optimum balance of schedule, cost and ALARA with minimum risks. An overview of the decommissioning progress to date plus overall perspectives of the factors facing utilities in this area will be reviewed

  8. HTGR startup experience at Fort St. Vrain

    International Nuclear Information System (INIS)

    Fort St. Vrain Unit 1, a 330-MW(e) HTGR being built by General Atomic for the Public Service Co. of Colorado, is located about 40 miles north of Denver. Construction began in 1968 and fuel was loaded under the first phase of the two-phase license in January 1974. The reactor has been critical a number of times to perform physics tests, but has been restrained until recently from producing any sensible heat by the restrictions of the second phase of the license. All prerequisites to the second and last phase of the license were satisfied on November 14 and the 40-year, full-power license went into effect. Since then, hot physics tests have been performed and feedwater has been introduced into the steam generators. All prerequisite testing is complete and feedwater chemistry is within specification for steam generator boilout. The plant is presently shut down and in a standby condition while the backup pelton wheels on the four primary helium circulators are being changed to an improved material. Upon completion of this change, now scheduled for the end of January, the rise-to-power program will begin.

    1983-10-01

    The US Coast Guard Station, Fort Point is located three-quarters of a nautical mile southeast of the Golden Gate Strait, the entrance to San Francisco Bay. The existing storm wave conditions at Fort Point Station pier make it extremely dangerous for the SAR crews to get on and off the Motor Life Boats at times requiring the vessels to be moored at the San Francisco Yacht Harbor about 1.5 miles east of the Fort Point Station. To mitigate these harsh working conditions the US Coast Guard is considering the feasibility of constructing suitable all-weather moorings for the three Motor Life Boats at the Fort Point Station to enable unimpeded SAR operations, to provide safe working conditions for Coast Guard small boat crews, and to improve small boat maintenance conditions at Fort Point Station. The purpose of this report is to identify, analyze and evaluate physical environmental factors that could affect all-weather moorings siting, configuration and entrance location, as well as potential post construction alterations to littoral conditions and processes. This report includes a description of the site, description of pertinent littoral processes, evaluation of how these processes could affect construction of all-weather moorings, and discussion of design considerations, as well as mitigation measures to minimize potential adverse effects to the physical environment. 19 references, 27 figures, 26 tables.

    The Le Fort I osteotomy is performed under general anaesthesia and specific haemodynamic conditions, i.e. hypotensive general anaesthesia. This study assessed the incidence of the trigeminocardiac reflex (TCR) during the different stages of the Le Fort I osteotomy. Forty-seven patients requiring a Le Fort I osteotomy were included. General anaesthesia was induced. In terms of haemodynamic changes, each patient's oxygen saturation (SpO2), mean arterial pressure (MAP), heart rate (HR), and electrocardiogram (ECG) were monitored by SADAAT Monitoring System and recorded during the different stages of osteotomy: before the induction of anaesthesia, before osteotomy cuts, after finishing the right pterygoid plate osteotomy, after finishing the left pterygoid plate osteotomy, and after performing down-fracture of the maxilla. No significant alteration in haemodynamic values was seen at the different stages of Le Fort I osteotomy. One patient showed arrhythmia with non-sinus junction rhythm after sinus bradycardia and two premature atrial contractions in the down-fracture stage, which led to the abrupt cessation of the procedure by the surgeon. This study showed no significant alterations in haemodynamic values during the different stages of Le Fort I osteotomy. Halting the procedure momentarily was sufficient to allow spontaneous normalization of the HR, blood pressure, and dysrhythmia. PMID:26794400

  13. Thunderstorm and Lightning Studies using the FORTE Optical Lightning System (FORTE/OLS)

    International Nuclear Information System (INIS)

    Preliminary observations of simultaneous RF and optical emissions from lightning as seen by the FORTE spacecraft are presented. RF/optical pairs of waveforms are routinely collected both as individual lightning events and as sequences of events associated with cloud-to-ground (CG) and intra-cloud (IC) flashes. CG pulses can be distinguished from IC pulses based on the properties of the RF and optical waveforms, but mostly based on the associated RF spectrograms. The RF spectrograms are very similar to previous ground-based VHF observations of lightning and show signatures associated with return strokes, stepped and dart leaders, and attachment processes,. RF emissions are observed to precede the arrival of optical emissions at the satellite by a mean value of 280 microseconds. The dual phenomenology nature of these observations are discussed in terms of their ability to contribute to a satellite-based lightning monitoring mission

    The Fort McMurray Historic Uranium Cleanup Project involved the removal of 42,000 m{sup 3} of soils contaminated with uranium ores and ore concentrates from various properties in the City of Fort McMurray, Alberta. These soils were placed into long-term management in a dedicated, locally developed and secure facility. The soil contamination addressed by the program was the result of incidental spillage and tracking of ores during the unloading of barges and the loading of rail cars as materials were transported via Fort McMurray from uranium mines in the Northwest Territories to a refinery in Port Hope, Ontario. The project was executed over a 10- year time period, involved the participation of the local community at critical junctures, and restored 28 ha of land to productive use. (author)

  18. Construction experience on PCRV liners at Fort St. Vrain

    International Nuclear Information System (INIS)

    The construction of the steel liners for the Fort St. Vrain prestressed concrete reactor vessel presented many unique problems for which techniques were developed to satisfy the rigid specification requirements. The PCRV cavity liner was fabricated from 1.9cm carbon steel plate. The liners were partially fabricated by Pittsburgh-Des Moines Steel Company at their Pittsburgh manufacturing facility. The liners were then shipped by rail to within approximately five miles of the jobsite and then trucked the remaining distance. The construction techniques, dimensional control, concrete support and testing utilized on the Fort St. Vrain project are presented in detail and demonstrate the flexibility of the PCRV for field construction.

    International Nuclear Information System (INIS)

    The Nuclear Aircraft Research Facility was established by Convair, Fort Worth, in 1950 under U.S. Air Force auspices to support the Aircraft Nuclear Propulsion Program in the areas of shielding and radiation effects problems affecting the airframe. The company subsequently became General Dynamics, Fort Worth. In 1954, an experimental shielding program was developed by B.P. Leonard and N.M. Schaeffer that incorporated air, ground, and structure scattering experiments with three sources: a large Co source, the gorund test reactor (GTR), and finally, the aircraft shield test reactor (ASTR). Shield penetration measurements were also planned with the GTR. Principal elements of this program are summarized in the paper

  16. Fort Peck-Wolf Point transmission line project, Montana

    International Nuclear Information System (INIS)

    The primary objective of the project is to replace the existing 36-mile Fort Peck-Wolf Point transmission line which has reached the end of its useful service life. Presently, the overall condition of this existing section of the 47-year-old line is poor. Frequent repairs have been required because of the absence of overhead ground wires. The continued maintenance of the line will become more expensive and customer interruptions will persist because of the damage due to lightning. The expense of replacing shell rotted poles, and the concern for the safety of the maintenance personnel because of hazards caused by severe shell rot are also of primary importance. The operational and maintenance problems coupled with power system simulation studies, demonstrate the need for improvements to the Wolf Point area to serve area loads. Western's Wolf Point Substation is an important point of interconnection for the power output from the Fort Peck Dam to area loads as far away as Williston, North Dakota. The proposed transmission line replacement would assure that there will continue to be reliable transmission capacity available to serve area electrical loads, as well as provide a reliable second high-voltage transmission path from the Fort Peck generation to back-up a loss of the Fort Peck-Wolf Point 115-kV Line No. 1

  18. Microbiological and other characteristics of chicken breast meat following electron-beam and sous-vide treatments

    International Nuclear Information System (INIS)

    The combined effects of radiation and sous-vide treatment of chicken breast meat were investigated with respect to survival and growth of Listeria monocytogenes, shelf life, thiamine content, and sensory qualities. Chicken breasts were inoculated with L. monocytogenes 81-861 (10(5) CFU/G), vacuum-packed, irradiated with electron beam (EB) up to 2.9 kGy, and cooked to an internal temperature of 65.6 degrees C. Sous-vide treatment alone had marginal lethal effect on the L. monocytogenes; the residual inoculum reached 10(7) CFU/g after 8 weeks at 2 degrees C. However, after the combined treatments of sous-vide and EB at 2.9 kGy, the organism remained undetectable during the 8-week storage period. Parallel studies on uninoculated breast meat revealed that sous-vide samples had a shelf life of less than 6 weeks without EB treatment, whereas samples that were irradiated and then received sous-vide treatment had a shelf life of at least 8 weeks. There was a slight reduction in thiamine levels as a result of the EB treatment, but there was essentially no additional loss of thiamine due to the subsequent sous-vide treatment and storage at 2 degrees C. Electron-beam treatment had very little effect on the odor and flavor of the reheated samples. It was concluded that EB treatment combined with, sous-vide treatment can greatly enhance the microbial safety and shelf life of chicken breast meat

    Pressure or water level measurements have been performed by GTC in different wells at the geothermal testsite Soultz-sous-Forets for six years now. The water lever variations are mainly influenced by earth tides, barometric pressure variations, hydraulic testing and stimulation. The small scale variations are influenced by tidal and barometric forcing functions, the large scale variations by hydraulic testing and stimulation. By analyzing such measurements it is possible to get important information about the hydrualic connections between the boreholes, as well as aquifer parameters. (orig./AKF)

  6. Measurements of transionospheric radio propagation parameters using the FORTE satellite

    International Nuclear Information System (INIS)

    We report initial measurements of ionospheric propagation parameters, particularly the total electron content (TEC), using the recently launched FORTE satellite. FORTE, which orbits the Earth at an altitude of 800 km and an inclination of 70 degree, contains a set of wideband radio receivers whose output is digitally recorded. A specialized triggering circuit identifies transient, broadband radio events, which include radiation from lightning, transionospheric pulse pairs, and man-made sources. Event data are transmitted to the ground station for analysis. In this paper we examine signals transmitted from an electromagnetic pulse generator operated at Los Alamos. The transmitter produces nearly impulsive signals in the VHF range. The received signal is dispersed by the ionosphere, and the received signal can be analyzed to deduce the total electron content along the path. By comparing the slant TEC thus measured with results from a ray-tracing code, we can deduce the vertical TEC to 800 km. Data from eight passes are presented. These types of data (in larger quantities) are of interest to operators of radar altimeters, who need data to corroborate their corrections for the ionospheric TEC. The combination of FORTE TEC data to 800 km and TEC measurements to 20,000 km (the Global Positioning System orbital altitude) can provide useful information for assessing the validity of models of plasmaspheric electron density. Initial estimates of the plasmaspheric density, on two daytime passes, are about 6 TECU. The signal received by FORTE, which is linearly polarized at the transmitter, is split into two magnetoionic modes by the ionosphere. The receiving antenna is also linearly polarized and therefore receives both modes. By measuring the beat frequency between the two modes, we can deduce the product of the geomagnetic field and the cosine of the angle between the field and the propagation vector. The possibility of using the measured slant TEC and the beat frequency to

  9. Decontamination and its role in the Fort St. Vrain decommissioning

    International Nuclear Information System (INIS)

    The full scale decommissioning of a reactor requires the use of a variety of decontamination processes, techniques and equipment. In August of 1992, the decommissioning of the Fort St. Vrain High Temperature Gas-Cooled Reactor (HTGR) was initiated by Public Service Company of Colorado. The Fort St. Vrain Decommissioning Project is being performed by a team comprised of Westinghouse Electric Corporation, Scientific Ecology Group, and MK Ferguson. This project is the largest decommissioning and early dismantlement of a commercially operated reactor in the United States to date. The scope of the project includes decontamination and dismantlement of the Prestressed Concrete Reactor Vessel (PCRV) and decontamination/removal of contaminated plant systems, site cleanup, and a comprehensive final radiation survey. This paper discusses the various types of decontamination equipment, survey instrumentation and techniques used during the Fort St. Vrain Decommissioning Project. Decontamination techniques range from simple methods such as soapy water, high pressure washing, scabbling, strippable paint; to more complicated methods such as remotely operated grit blast equipment used to decontaminate embedded pipe. The parameters necessary to evaluate the cost effectiveness of various decontamination techniques are discussed. Typically this includes consideration of the type and level of contamination, the substrate and surface to be decontaminated, the type and volume of waste generated from the decontamination process, whether the decon will be performed on site or off site, equipment and labor costs, project schedule impact, and the unconditional release criteria that must be achieved. These factors and costs are then compared to the costs associated with the removal, possible volume reduction and final disposal of a particular component or system. The successes and lessons learned during the Fort St. Vrain Decommissioning Project are presented

    Full Text Available Studies that measure the brand equity of destination brands by using the Customer-Based Brand Equity (CBBE model in a developing country context are scarce. The present study investigates the destination brand equity of the Lahore Fort by employing the CBBE model in a developing country context of Pakistan. Following the positivist tradition, we adopted a survey-based approach to collect data from 237 tourists visiting the Lahore Fort. Data were collected through a questionnaire developed to explain the relationship of brand awareness, brand image, brand association, and brand loyalty with Lahore Fort’s overall brand equity. We used various robust statistical techniques such as correlation, regression and confirmatory factor analysis (using PLS method to reach meaningful conclusions and found that brand image and brand associations positively contribute to brand loyalty. Furthermore, brand loyalty significantly contributes towards overall brand equity. Pragmatically, this study measures the customer based brand equity of the Lahore Fort, a destination brand. The results are useful as they suggest a few strategies that can help policy makers to enhance Lahore Fort’s brand performance.

  13. An aerial radiological survey of the Fort Calhoun Nuclear Power Plant and surrounding area, Fort Calhoun, Nebraska

    International Nuclear Information System (INIS)

    An aerial radiological survey was conducted over the Fort Calhoun Nuclear Power Plant in Fort Calhoun, Nebraska, during the period June 19 through June 28, 1993. The survey was conducted at an altitude of 150 feet (46 meters) over a 25-square-mile (65-square-kilometer) area centered on the power station. The purpose of the survey was to document the terrestrial gamma radiation environment of the Fort Calhoun Nuclear Power Plant and surrounding area. The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 6 and 12 microroentgens per hour and were attributed to naturally-occurring uranium, thorium, and potassium. The aerial data were compared to ground-based benchmark exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system. A previous survey was conducted on August 9 and 10, 1972, before the plant began operation. Exposure rates measured in both surveys were consistent with normal terrestrial background

    The Fort St. Vrain Nuclear Generating Station, the first and only commercial High Temperature Gas Cooled Reactor to operate in the United States, completed initial fuel loading in late 1973 and initial startup in early 1974. Due to a series of non-nuclear technical problems, Fort St. Vrain never operated consistently, attaining a lifetime capacity factor of slightly less than 15%. In August of 1989, the decision was made to permanently shut down the plant due to control rod drive and steam generator ring header failures. Public Service Company of Colorado elected to proceed with early dismantlement (DECON) as opposed to SAFSTOR on the bases of perceived societal benefits, rad waste, and exposure considerations, regulatory uncertainties associated with SAFSTOR, and cost. The decommissioning of Fort St. Vrain began in August of 1992, and is scheduled to be completed in early 1996. Decommissioning is being conducted by a team consisting of Westinghouse, MK-Ferguson, and Scientific Ecology Group. Public Service Company of Colorado as the licensee provides contract management and oversight of contractor functions. An aggressive program to maintain project radiation exposures As Low As Reasonably Achievable (ALARA) has been established, with the following program elements: temporary and permanent shielding contamination control; mockup training; engineering controls; worker awareness; integrated work package reviews communication; special instrumentation; video camera usage; robotics application; and project committees. To date, worker exposures have been less than project estimates. from the start of the project through Februrary of 1994, total exposure has been 98.666 person-rem, compared to the project estimate of 433 person-rem and goal of 347 person-rem. The presentation will discuss the site characterization efforts, the radiological performance indicator program, and the final site release survey plans

  17. Operating experience with the Fort St. Vrain Nuclear Power Station

    International Nuclear Information System (INIS)

    Since entering into commercial operation in 1979, the 330 MW(e) Fort St. Vrain HTGR has performed increasingly well, and it is now demonstrating the real promise of this advanced reactor type. As of this writing, the plant has operated routinely at 70% power with 38% thermal efficiency, the highest nuclear plant efficiency in the United States of America, and has generated over 2,500,000 MW.h of electricity. Monthly availability factors have reached 99%. The plant has operated in a testing mode over 90% power and reached full power on 6 November 1981. Fuel performance has continued to exceed expectations and the second refuelling was carried out in 1981 (the first was in 1979). Radioactivity levels in the helium coolant and around the plant are very low. Personnel exposure during 1979-80, computed on a unit electricity generated basis, was a few per cent of the average exposure at LWR plants. This paper reviews the lessons learned during the startup and first five years of operation of Fort St. Vrain, including core behaviour, fuel handling, helium coolant cleanup, primary system and balance-of-plant component and systems operation, and plant operation and maintenance experience. In addition, the ways in which the new regulations resulting from the accident at Three Mile Island have been implemented in this HTGR plant are described. Public Service Co. of Colorado and General Atomic Co. have, through Fort St. Vrain, generated a large base of experience in HTGR technology that can be applied to future projects in the United States and elsewhere.

    As part of the Army Net-Zero Energy Installation program, the Fort Carson Army Base requested that NREL evaluate the feasibility of adding a biomass boiler to the district heating system served by Building 1860. We have also developed an Excel-spreadsheet-based decision support tool--specific to the historic loads served by Building 1860--with which users can perform what-if analysis on gas costs, biomass costs, and other parameters. For economic reasons, we do not recommend adding a biomass system at this time.

  19. Decommissioning of Fort St. Vrain nuclear generating station

    International Nuclear Information System (INIS)

    In the U.S.A., a licensee can propose decontaminating a nuclear power plant using any of three methods: DECON, SAFSTOR, or ENTOMB. For the Fort St. Vrain reactor, DECON was chosen. According to this option, portions of the facility, containing radioactive contaminants, are dismantled and removed, or else decontaminated, soon after the cessation of power. The work to be done is of three kinds: decontamination and dismantlement of the pre-stressed concrete reactor vessel; decontamination or dismantling of actually or potentially contaminated balance of plant; and site cleanup and final site radiation survey. Each of these elements of the work is discussed

  20. Dynamic computer simulation of the Fort St. Vrain steam turbines

    International Nuclear Information System (INIS)

    A computer simulation is described for the dynamic response of the Fort St. Vrain nuclear reactor regenerative intermediate- and low-pressure steam turbines. The fundamental computer-modeling assumptions for the turbines and feedwater heaters are developed. A turbine heat balance specifying steam and feedwater conditions at a given generator load and the volumes of the feedwater heaters are all that are necessary as descriptive input parameters. Actual plant data for a generator load reduction from 100 to 50% power (which occurred as part of a plant transient on November 9, 1981) are compared with computer-generated predictions, with reasonably good agreement

  1. A reactivity accidents simulation of the Fort Saint Vrain HTGR

    International Nuclear Information System (INIS)

    A reactivity accidents analysis of the Fort Saint Vrain HTGR was made. The following accidents were analysed 1) A rod pair withdrawal accident during normal operation, 2) A rod pair ejection accident, 3) A rod pair withdrawal accident during startup operations at source levels and 4) Multiple rod pair withdrawal accident. All the simulations were performed by using the BLOOST-6 nuclear code The steady state reactor operation results obtained with the code were consistent with the design reactor data. The numerical analysis showed that all accidents - except the first one - cause particle failure. (author)

The simulation of split Hopkinson bar loading histories modelling the complete test setup within an explicit finite element code yields good agreement with experimental results. The introduction of the dynamic damage relaxation into the constitutive law also prevents spurious mesh sensitive localisation during the solution of wave propagation problems. The simulation of concrete perforation experiments demonstrates the strain rate effect on the penetration resistance in high velocity impact problems. (orig.) [German] Experimentelle Untersuchungen zum dynamischen Bruchverhalten von Beton weisen eine kurzzeitige Festigkeitssteigerung nach, die mit der Dehnrate ueberproportional zunimmt. Die dynamische Spannungs-Dehnungs-Beziehung von Beton wird darueber hinaus nicht nur von der jeweils herrschenden Dehnrate bestimmt, sondern von der gesamten Belastungsgeschichte. Trotz dieser Erkenntnisse wird der Dehnrateneffekt in Hydrocodes in der Regel ueber einfachste Festigkeitssteigerungsfaktoren im Stoffgesetz definiert, die nur von der aktuellen Dehnrate abhaengen. Dynamische Belastungsgeschichten mit Be- und Entladung, die z.B. mit der Split-Hopkinson-Bar Apparatur gemessen werden, koennen mit diesen Ansaetzen nicht abgebildet werden.

    Most resource management decisions involve the integrated use of biological, sociological, and economic information. Combining this information provides a more comprehensive basis for making effective land management and conservation decisions. Toward this end, scientists in the Policy Analysis and Science Assistance Branch (PASA) of the Fort Collins Science Center (FORT) contribute expert knowledge for natural resources management by conducting biological, social, economic, and institutional analyses of conservation policies and management practices. PASAi??s mission is to integrate biological, social, and economic research so that resource managers can use the resulting information to make informed decisions and resolve resource management confl icts. PASA scientists pursue and conduct scientific analyses that help agencies and Native American tribes to (1) identify impending policy controversies and areas where social and natural science research is needed to address future policy questions; (2) develop methods and approaches to assist researchers in preparing scientific evidence; (3) assess habitat alteration in a manner consistent with policy needs; and (4) evaluate policy options. Branch scientists also evaluate policy options (e.g., effects of different land treatments, fish and wildlife management practices, or visitor/recreation management practices) in response to specifi c questions faced by policymakers and managers.

  8. Strategic Energy Management Plan For Fort Buchanan, Puerto Rico

    Energy Technology Data Exchange (ETDEWEB)

    Parker, Steven A.; Hunt, W. D.

    2001-10-31

    This document reports findings and recommendations as a result of a design assistance project with Fort Buchanan with the goals of developing a Strategic Energy Management Plan for the Site. A strategy has been developed with three major elements in mind: 1) development of a strong foundation from which to build, 2) understanding technologies that are available, and 3) exploring financing options to fund the implementation of improvements. The objective of this report is to outline a strategy that can be used by Fort Buchanan to further establish an effective energy management program. Once a strategy is accepted, the next step is to take action. Some of the strategies defined in this Plan may be implemented directly. Other strategies may require the development of a more sophisticated tactical, or operational, plan to detail a roadmap that will lead to successful realization of the goal. Similarly, some strategies are not single events. Rather, some strategies will require continuous efforts to maintain diligence or to change the culture of the Base occupants and their efforts to conserve energy resources.

    The US Army Forces Command (FORSCOM) has tasked the US Department of Energy (DOE) Federal Energy Management Program (FEMP), supported by the Pacific Northwest Laboratory, to identify, evaluate, and assist in acquiring all cost-effective energy projects at Fort Stewart. This is part of a model program that PNL is designing to support energy-use decisions in the federal sector. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at the FORSCOM Fort Stewart facility located approximately 25 miles southwest of Savannah, Georgia. It is a companion report to Volume 1, Executive Summary, and Volume 2, Baseline Detail. The results of the analyses of EROs are presented in 11 common energy end-use categories (e.g., boilers and furnaces, service hot water, and building lighting). A narrative description of each ERO is provided, along with a table detailing information on the installed cost, energy and dollar savings; impacts on operations and maintenance (O&M); and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. A description of the evaluation methodologies and technical and cost assumptions is also provided for each ERO. Summary tables present the cost-effectiveness of energy end-use equipment before and after the implementation of each ERO. The tables also present the results of the life-cycle cost (LCC) analysis indicating the net present value (NPV) and savings to investment ratio (SIR) of each ERO.

    The Directorate of Public Works Environmental & Natural Resources Division (Fort Stewart /Hunter Army Airfield) contracted with the Pacific Northwest National Laboratory (PNNL) to monitor particulate matter (PM) concentrations on Fort Stewart, Georgia. The purpose of this investigation was to establish a PM sampling network using monitoring equipment typically used in U.S. Environmental Protection Agency (EPA) ''saturation sampling'', to determine air quality on the installation. In this initial study, the emphasis was on training-generated PM, not receptor PM loading. The majority of PM samples were 24-hr filter-based samples with sampling frequency ranging from every other day, to once every six days synchronized with the EPA 6th day national sampling schedule. Eight measurement sites were established and used to determine spatial variability in PM concentrations and evaluate whether fluctuations in PM appear to result from training activities and forest management practices on the installation. Data collected to date indicate the average installation PM2.5 concentration is lower than that of nearby urban Savannah, Georgia. At three sites near the installation perimeter, analyses to segregate PM concentrations by direction of air flow across the installation boundary indicate that air (below 80 ft) leaving the installation contains less PM2.5 than that entering the installation. This is reinforced by the observation that air near the ground is cleaner on average than the air at the top of the canopy.

  11. Solar Energy Development Assistance for Fort Hunter Liggett

    2011-03-30

    Pacific Northwest National Laboratory provided assistance to Fort Hunter Liggett to determine the opportunities for solar energy development on the site. Increasing use of renewable energy is mandated by several executive orders and legislation. Fort Hunter Liggett has many attributes that enhance its suitability for renewable energy development. First, the site is located south of San Francisco in a remote portion of the costal foothills. Brush and forest fires are frequent and often result in power outages, which subsequently impacts the site’s training mission. In addition, the site’s blended electric rate during fiscal year (FY) 2010 was high at 12 ¢/kWh. Lastly, the solar resource is moderately high; the site receives nearly 5.7 kWh/m2/day on a south facing, latitude-tilted surface. In light of these factors, the site is a clear candidate for a solar photovoltaic array. Prior to Pacific Northwest National Laboratory’s (PNNL) involvement, the site secured funding for a 1 megawatt (MW) photovoltaic (PV) array that will also provide shading for site vehicles. To best implement this project, PNNL conducted a site visit and was tasked with providing the site technical guidance and support regarding module selection, array siting, and other ancillary issues.

    2006-01-01

    Objective:To evaluate the usefulness of twodimensional (2D) and three-dimensional (3D) computed tomography (CT) in the identification and classification of Le Fort type fractures.Methods: Sixty-two patients with different types of Le Fort fractures underwent CT scanning and 3D-CT reconstruction. The data were analyzed by multiplanar reconstruction (MPR), surface shaded display (SSD) and volume rendering (VR) respectively.Results: The patients with Le Fort Ⅰ , Le Fort Ⅱfracture and Le Fort Ⅲ fracture accounted for 16.1%,14.5 % and 12.9 % respectively. The compound fractures were the most common type and accounted for 56.5 % ( n =35, 18 cases with Le Fort Ⅰ + Ⅱ fracture, 10 cases with Le Fort Ⅱ + Ⅲ fracture and 7 cases with Le Fort Ⅰ + Ⅱ + Ⅲfracture). Fifty-five cases coexisted with other fractures in maxillofacial region. 2D-CT could be used to define the tiny fractures and the deep-structure fractures more accurately compared with 3D-CT, but the real impression of Le Fort type fractures could not be correctly evaluated on 2D-CT.3D-CT could clearly demonstrate the whole shape of Le Fort type fractures and identify the classification of Le Fort fractures.Conclusions: 3D-CT is the best imaging method for the diagnosis of Le Fort type fractures and can provide valuable information of space relationship, especially for the design of treatment plan before operation.

  20. Revisiting "Narrow Bipolar Event" intracloud lightning using the FORTE satellite

    Directory of Open Access Journals (Sweden)

    A. R. Jacobson

    2012-02-01

    Full Text Available The lightning stroke called a "Narrow Bipolar Event", or NBE, is an intracloud discharge responsible for significant charge redistribution. The NBE occurs within 10–20 μs, and some associated process emits irregular bursts of intense radio noise, fading at shorter timescales, sporadically during the charge transfer. In previous reports, the NBE has been inferred to be quite different from other forms of lightning strokes, in two ways: First, the NBE has been inferred to be relatively dark (non-luminous compared to other lightning strokes. Second, the NBE has been inferred to be isolated within the storm, usually not participating in flashes, but when it is in a flash, the NBE has been inferred to be the flash initiator. These two inferences have sufficiently stark implications for NBE physics that they should be subjected to further independent test, with improved statistics. We attempt such a test with both optical and radio data from the FORTE satellite, and with lightning-stroke data from the Los Alamos Sferic Array.

    We show rigorously that by the metric of triggering the PDD optical photometer aboard the FORTE satellite, NBE discharges are indeed less luminous than ordinary lightning. Referred to an effective isotropic emitter at the cloud top, NBE light output is inferred to be less than ~3 × 108 W.

    To address isolation of NBEs, we first expand the pool of geolocated intracloud radio recordings, by borrowing geolocations from either the same flash's or the same storm's other recordings. In this manner we generate a pool of ~2 × 105 unique and independent FORTE intracloud radio recordings, whose slant range from the satellite can be inferred. We then use this slant range to calculate the Effective Radiated Power (ERP at the radio source, in the passband 26–49 MHz. Stratifying the radio recordings by ERP into eight bins, from a lowest bin (<5 kW to a highest bin (>140 kW, we document a

  1. Effects of combined electron-beam irradiation and sous-vide treatments on microbiological and other qualities of chicken breast meat

    International Nuclear Information System (INIS)

    The microbiological safety, refrigeration shelf-life, and nutritional quality of chicken breast meat were investigated following combined electron-beam irradiation and cooking under vacuum (sous-vide). Chicken breast meat inoculated with 106 CFU/g of Listeria monocytogenes was irradiated with an electron beam at doses up to 3.1 kGy under vacuum in barrier bags, cooked in a boiling water bath for 3 min 45 s (previously determined to achieve an internal temperature of 71.1oC), and stored at 8oC for up to 5 weeks. Listeria was undetectable in samples treated with combined sous-vide and irradiation at 3.1 kGy, but the organism survived the sous-vide treatment without irradiation and multiplied during storage. A similar study, conducted with uninoculated chicken breast meat, revealed that the product which received both irradiation (3 kGy) and sous-vide treatment had a shelf-life of at least 8 weeks at 8oC, whereas the unirradiated samples treated sous-vide spoiled in 16 days. Listeria was undetectable in combination treated samples, but some of the unirradiated sous-vide samples tested after long storage showed high levels of Listeria. Some loss of thiamine occurred with the combined treatments. (author)

    2010-01-01

    La sous-traitance industrielle se traduit par une fragilisation de la santé et de la sécurité au travail. Une enquête auprès de travailleurs masculins de la sous-traitance dans l'industrie lourde montre qu'ils cumulent instabilités et pénibilités professionnelles avec de fréquentes atteintes à leur santé. La conscience des risques existe, mais plusieurs mécanismes l'atténuent, dont la persistance de stratégies défensives reposant sur la virilité et le métier. Mais le travail n'est pas seuleme...

  9. Sensitivity comparative study in Philips Forte Gamma Camera

    International Nuclear Information System (INIS)

    Monte Carlo modeling is widely used in the development nuclear medical imaging systems, particularly in the adjustment of its main characteristics and parameters. It is essential to evaluate the behavior of the system sensitivity in real measurement conditions for specific patient. Planar studies of thyroid phantom were conducted in a Philips Forte Gamma Camera of the 'Hermanos Ameijeiras' Hospital. Experimental set up was totally reproduced in the simulation environment. A comparative study between the experimental and theoretical, obtained by Monte Carlo mathematical modeling, sensitivity values have been done. For simulation GAMOS (Geant4-Architecture for medicine Oriented Simulation) framework was used. The results obtained from both methods have shown an acceptable coincidence (less than 2%) of sensitivity. Therefore this paper aims to validate sensitivity studies carried out via Monte Carlo mathematical modeling and irs acceptable equivalence with experimental measurements in authentic medical circumstances.

  10. Fort St. Vrain independent spent fuel storage installation

    International Nuclear Information System (INIS)

    The Independent Spent Fuel Storage Installation (ISFSI) at Fort St. Vrain was conceived initially as a contingency plan for one segment of high temperature gas cooled reactor (HTGR) fuel. As the project evolved, the ISFSI was eventually designed and constructed for six segments of HTGR fuel. The approximately two year schedule for design, licensing, and construction of the ISFSI was completed on schedule and at the anticipated cost of $25 million. Loading fuel from the reactor to the ISFSI was completed two months ahead of schedule at a cost savings of $1,500,000. Actual occupational exposure was less than 7% of projected exposure. This paper attempts to inform the reader about technical aspects of the Public Service Company of Colorado ISFSI and how design, licensing, construction, and loading of the ISFSI was completed ahead of schedule and under cost

  11. Preplaced aggregate concrete application on Fort St. Vrain PCRV construction

    International Nuclear Information System (INIS)

    Two distinct concreting methods were employed in the construction of the prestressed concrete reactor vessel (PCRV) of the Fort St. Vrain (FSV) Nuclear Generating Station, a 330 MW(e) High Temperature Gas-Cooled Reactor installation near Denver, Colorado. Preplaced aggregate concrete (PAC) techniques were employed in the PCRV bottom head and the core support floor; conventional job-mixed concrete was used in the PCRV sidewall and top head regions. This paper describes the successful application of PAC techniques utilized primarily in solving construction difficulties associated with confined and heavily congested regions of the PCRV. The PAC technique consists of placing coarse aggregate inside the forms, followed by injection of grout under pressure through embedded pipes to fill the interstices in the aggregate mass. Details of the PAC construction method including grout mix development, grouting equipment, grout pipe layout, grouting sequence, grout level monitoring, concrete temperature control, and pre-construction mockups are described.

  12. The HTGR experience base at Fort St. Vrain

    International Nuclear Information System (INIS)

    GA Technologies Inc. is designing large hightemperature gas-cooled reactors (LHTGR's) for central station power and cogeneration applications. The 330-MW(e) Fort St. Vrain (FSV) plant operated by Public Service Company of Colorado provides the principal technical base for designing LHTGR's. It has demonstrated the prestressed concrete reactor vessel, once-through steam generators, and hexagonal block fuel elements. To gain the maximum advantage from FSV, a systematic, formal Experience Carryover Program (ECP) is examining FSV experience from research and development through construction, operation, and maintenance. Design features resulting from the ECP, in conjunction with other programs, including extensive foreign experience, should result in high LHTGR reliability and operability. This paper explains the major design differences between FSV and the LHTGR

  13. Fort St. Vrain high temperature gas-cooled reactor

    International Nuclear Information System (INIS)

    The construction, testing, and preliminary operating experience of the Fort St. Vrain Nuclear Generating Station are described. This station utilizes the advanced high-temperature gas-cooled reactor (HTGR) concept and is the first nuclear reactor system in the United States to use a prestressed concrete reactor vessel (PCRV). Helium is used as the primary coolant, and a nitrogen system provides refrigeration for the low temperature equipment of the helium purification system and for the moisture monitors in the primary coolant system. Design, construction and testing to date at this station have made a significant contribution to the HTGR concept for central station electric generating plants to supply the increasing demands for electrical energy.

  16. Fort St. Vrain graphite site mechanical separation concept selection

    International Nuclear Information System (INIS)

    One of the alternatives to the disposal of the Fort St. Vrain (FSV) reactor spent nuclear fuel involves the separation of the fuel rods composed of compacts from the graphite fuel block assembly. After the separation of these two components, the empty graphite fuel blocks would be disposed of as a low level waste (provided the appropriate requirements are met) and the fuel compacts would be treated as high level waste material. This report deals with the mechanical separation aspects concerning physical disassembly of the FSV graphite fuel element into the empty graphite fuel blocks and fuel compacts. This report recommends that a drilling technique is the preferred choice for accessing the, fuel channel holes and that each hole is drilled separately. This report does not cover any techniques or methods to separate the triso fuel particles from the graphite matrix of the fuel compacts

    The Tularosa-Hueco basin in south-central New Mexico has long been known as an extensional area of high heat flow. Much of the basin is within the Fort Bliss military reservation, which is an exceptionally high value customer for power independent of the regional electric grid and for direct use energy in building climate control. A series of slim holes drilled in the 1990s established the existence of a thermal anomaly but not its practical value. This study began in 2009 with a demonstration of new exploration drilling technology. The subsequent phases reported here delivered a useful well, comparative exploration data sets and encouragement for further development. A production-size well, RMI56-5, was sited after extensive study of archival and newly collected data in 2010-2011. Most of 2012 was taken up with getting state and Federal authorities to agree on a lead agency for permitting purposes, getting a drilling permit and redesigning the drilling program to suit available equipment. In 2013 we drilled, logged and tested a 924 m well on the McGregor Range at Fort Bliss using a reverse circulation rig. Rig tests demonstrated commercial permeability and the well has a 7-inch slotted liner for use either in production or injection. An August 2013 survey of the completed well showed a temperature of 90 C with no reversal, the highest such temperature in the vicinity. The well’s proximity to demand suggests a potentially valuable resource for direct use heat and emergency power generation. The drilling produced cuttings of excellent size and quality. These were subjected to traditional analyses (thin sections, XRD) and to the QEMScan™ for comparison. QEMScan™ technology includes algorithms for determining such properties of rocks as density, mineralogy, heavy/light atoms, and porosity to be compared with direct measurements of the cuttings. In addition to a complete cuttings set, conventional and resistivity image logs were obtained in the open hole before

    The potential for air quality impacts from heavy mechanized vehicles operating in the training ranges and on the unpaved main supply routes at Fort Bliss is being investigated. The investigation uses the atmospheric modeling system DUSTRAN to simulate fugitive dust emission and dispersion from typical activities occurring on the installation. This report conveys the results of DUSTRAN simulations conducted using a “Full Training” scenario developed by Fort Bliss personnel. he Full Training scenario includes simultaneous off-road activities of two full Heavy Brigade Combat Teams (HCBTs) and one HCBT battalion on three training ranges. Simulations were conducted for the six-day period, April 25-30, 2005, using previously archived meteorological records. Simulation results are presented in the form of 24-hour average PM10 plots and peak 1-hour PM10 concentration plots, where the concentrations represent contributions resulting from the specified military vehicular activities, not total ambient PM10 concentrations. Results indicate that the highest PM10 contribution concentrations occurred on April 30 when winds were light and variable. Under such conditions, lofted particulates generated by vehicular movement stay in the area of generation and are not readily dispersed. The effect of training duration was investigated by comparing simulations with vehicular activity extending over a ten hour period (0700 to 1700 MST) with simulations where vehicular activity was compressed into a one hour period (0700 to 0800 MST). Compressing all vehicular activity into one hour led to higher peak one-hour and 24-hour average concentration contributions, often substantially higher.

Au sein de ce dispositif sont installées cinq bases de sous-marins : Dunkerque, Saint-Nazaire, Lorient, La Rochelle et Bordeaux. Après une période de purgatoire, liée aux souvenirs trop frais des bombardements qu’ils ont attirés sur les villes, les édifices du mur sont entrés dans la sphère de la culture et du tourisme. Nous posons alors la question suivante : de quoi ces édifices portent-ils témoignage, et nous envisageons plusieurs aspects : leur évident modernisme qui les situe à un moment de l’histoire de l’architecture, leur hétérogénéité qui fait de ces bâtiments des sortes d’ovni, sans aucun rapport ni d’échelle ni de forme avec l’architecture civile, une technique d’enfouissement et de camouflage génératrice d’un nouveau paysage. Mais ces édifices peuvent-ils être exonérés de leur but guerrier ? Quel est le message de leur recyclage dans le culturel, le festif ou le commercial ? Deux bases de sous-marins sont plus particulièrement présentées, celle de Saint-Nazaire et celle de Lorient.The Atlantic Wall stretches from the Spanish border to northern Norway. Within this system there are five bases for submarines: Dunkirk, Saint-Nazaire, Lorient, La Rochelle and Bordeaux. After a period of purgatory, with the painful memories of the wartime air raids which destroyed the cities around the bases, the buildings which the Atlantic Wall comprises have now entered the spheres of culture and tourism. What do these buildings bear witness to? Their frank modernism puts them at a precise moment in the history of architecture. Their heterogeneity makes them like UFOs, without any relation of scale or form to civil architecture. Their specific techniques of dissimulation and camouflage created new landscapes. But can these buildings be freed from the memories of their original military purpose? What message is

    The dynamic expansion of the ready-to-eat seabream sector in its adaptation to new lifestyles has led to the search for new presentation formats in seabream (Sparus aurata). Green sauce (olive oil, wine vinegar, garlic, fresh parsley, black pepper, basil and salt) and 60 ℃ of cooking temperature were chosen by the panellists for the sous vide cooking process. Seabream fillet and sauce were packaged in polypropylene trays, cooked, chilled and stored at 2 ℃. Microbiological (total viable counts,Enterobacteriaceae,lactic acid bacteria, anaerobic psychrotrophic, moulds and yeasts, Salmonella and Listeria monocytogenes), chemical (pH and TBARs) and sensory parameters were determined at 0, 7, 17, 34, 48 and 62 days. In the conditions used, the microbiological counts remained stable, and Salmonella and Listeria monocytogenes were absent. The acidic sauce had a positive effect on the pH of the product, and low TBARs were obtained throughout storage. The processing conditions used in the present study allowed a chilled ready-to-eat seabream product of consistently high quality up to 62 days of storage to be obtained, representing an expansion of the products offered by the aquacultural industry.

    Dans le cadre de la construction du nouveau distributeur à ferrites BIDIS situé dans la ligne de transfert du Linac4 vers l’injecteur Booster du complexe PS, il est nécessaire de réaliser un nouveau développement de traversée haute tension pour assurer l’alimentation de ces septa sous vide. De manière à éviter toute pollution des enceintes de l’accélérateur en cas de fuite de vide, il a été choisi de développer une traversée n’utilisant ni liquide, ni gaz isolant. Cette technologie nous incite à faire une étude de design plus poussée, dans le choix des formes géométriques des pièces constituant ces traversées, ainsi que des distances à respecter entre les différentes parties soumises à la haute tension, afin d’éviter tous claquages ou apparition de courant limitant la tenue à la haute tension.

    An installation has been set up for carrying out manipulations and chemical analyses on radioactive products. It is completely remote-controlled and is of linear shape, 15 metres long; it is made up of three zones: - an active zone containing the apparatus, - a rear zone giving access to the active zone, - a forward zone independent of the two others and completely protected from which the remote-control of the apparatus is effected. The whole assembly has been designed so that each apparatus corresponding to an analytical technique is set up in a sealed enclosure. The sealed enclosures are interconnected by a conveyor. After three years operation, a critical review is now made of the installation.

    Experimental batches of smoked-cured pork in stewed beans sauce were inoculated with spores of psychrotrophic Bacillus cereus, more heat and radiation resistant than spores of non-proteolytic C. botulinum. After vacuum packaging, the meals were treated with combinations of pasteurizing heat treatments and gamma irradiation of 5 kGy. Prior and after treatments, and periodically during storage at 10°C, total aerobic and total anerobic viable cell counts, and selectively, the viable cell counts of B. cereus and sulphite-reducing clostridia have been determined. The effects of the treatment order as well as addition of nisin to enhance the preservative efficiency of the physical treatments were also studied. Heat-sensitization of bacterial spores surviving irradiation occurred. The quality-friendly sous-vide cooking in combination with this medium dose gamma irradiation and/or nisin addition increased considerably the microbiological safety and the keeping quality of the meals studied. However, approx. 40% loss of thiamin content occurred as an effect of combination treatments, and adverse sensorial effects may also limit the feasible radiation doses or the usable concentrations of nisin.

    2015-02-01

    This paper is composed of three elements: 3D modeling, web design, and heritage visualization. The aim is to use computer graphics design to inform and create an interest in historical visualization by rebuilding Fort Frontenac using 3D modeling and interactive design. The final model will be integr ated into an interactive website to learn more about the fort's historic imp ortance. It is apparent that using computer graphics can save time and money when it comes to historical visualization. Visitors do not have to travel to the actual archaeological buildings. They can simply use the Web in their own home to learn about this information virtually. Meticulously following historical records to create a sophisticated restoration of archaeological buildings will draw viewers into visualizations, such as the historical world of Fort Frontenac. As a result, it allows the viewers to effectively understand the fort's social sy stem, habits, and historical events.

    Nous rapportons les résultats de la chirurgie coronaire chez une population de coronariens diabétiques opérés sous circulation extra-corporelle dans le service de chirurgie cardiaque de l'hôpital militaire d'instruction Mohammed V de Rabat. C'est une étude rétrospective menée entre Janvier 2008 et Février 2012 (4 ans), portant sur 103 patients diabétiques consécutifs opérés pour pontage coronaire. L’âge moyen des patients était de 61±8,7ans (37-82ans) avec un sexe ratio (H/F) de 3,9. Tous les patients diabétiques de type 2 et sous traitement anti-diabétique ont été inclus dans cette étude. La sténose du tronc commun gauche était présente chez 26,2% des patients et 53,4% étaient tritronculaires. Quatre-vingt patients (78,6%) étaient insulino-nécessitant, l'Euro-score moyen était de 1,63±1% et le nombre moyen de pontage de 2,3±0,7. Les durées moyennes de la circulation extra-corporelle et du clampage aortique étaient respectivement de 134,4 ± 42 min et 76 ± 28 min. La mortalité hospitalière était de 2 décès (1,9%), les durées moyennes de ventilation artificielle, du séjour en réanimation et du séjour postopératoire étaient respectivement de 7h (5-16h), 48h (42-52h) et 15,6 ± 8,6 jours. Les complications postopératoires étaient l'infarctus du myocarde, l'infection de paroi, la médiastinite et le bas débit cardiaque chez respectivement 1,9%, 10,7%, 3,9% et 1,9% des patients. Il ressort de notre étude, que les facteurs prédictifs d'infection post opératoire étaient la durée de ventilation artificielle (p = 0,002), la durée de la circulation extra-corporelle (p < 0,001) en plus du tabac (p = 0,004) et de l'obésité (p = 0,005).

    2010-04-01

    The Robotics Rodeo held from 31 August to 3 September 2009 at Fort Hood, Texas, had three stated goals: educate key decision makers and align the robotics industry; educate Soldiers and developers; and perform a live market survey of the current state of technologies to encourage the development of robotic systems to support operational needs. Both events that comprised the Robotics Rodeo, the Extravaganza and the robotic technology observation, demonstration and discussion (RTOD2) addressed these stated goals. The Extravaganza was designed to foster interaction between the vendors and the visitors who included the media, Soldiers, others in the robotics industry and key decision makers. The RTOD2 allowed the vendors a more private and focused interaction with the subject matter experts teams, this was the forum for the vendors to demonstrate their robotic systems that supported the III Corps operational needs statements that are focused on route clearance, convoy operations, persistent stare, and robotic wingman. While the goals of the Rodeo were achieved, the underlying success from the event is the development of a new business model that is focused on collapsing the current model to get technologies into the hands of our warfighters quicker. This new model takes the real time data collection from the Rodeo, the Warfighter Needs from TRADOC, the emerging requirements from our current engagements, and assistance from industry partners to develop a future Army strategy for the rapid fielding of unmanned systems technologies.

  7. Fort Stewart integrated resource assessment. Volume 1, Executive summary

    Larson, L.L.; Keller, J.M.

    1993-10-01

    The US Department of Energy (DOE) Federal Energy Management Program (FEMP), supported by the Pacific Northwest Laboratory (PNL), has developed a model program that provides a systematic approach to evaluating energy opportunities that (1) identifies the building groups and end uses that use the most energy (not just have the greatest energy-use intensity), and (2) evaluates the numerous options for retrofit or installation of new technology that will result in the selection of the most cost-effective technologies. In essence, this model program provides the federal energy manager with a roadmap to significantly reduce energy use in a planned, rational, cost-effective fashion that is not biased by the constraints of the typical funding sources available to federal sites. The results from this assessment process can easily be turned into a five- to ten-year energy management plan that identifies where to start and how to proceed in order to reach the mandated energy consumption targets. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at the US Army US Forces Command (FORSCOM) Fort Stewart facility located approximately 25 miles southwest of Savannah, Georgia. It is a companion report to Volume 2, Baseline Detail, and Volume 3, Resource Assessment.

  8. Fort St. Vrain-A DOE Success Story.

    2003-02-01

    ABSTRACT The Fort St. Vrain Nuclear Generating Station was a one-of-its-kind High Temperature Gas Cooled Reactor located near Denver, CO. Due to operational difficulties, the reactor was permanently shut down in August 1989. Plans to ship the spent reactor fuel to Idaho were thwarted by the Governor of Idaho. The inability to ship the spent reactor fuel offsite necessitated the construction of an Independent Spent Fuel Storage Installation (ISFSI) in order to proceed with the decommissioning of the reactor. After loading the ISFSI, decommissioning of the reactor was initiated and successfully completed. At the same time, the site was repowered using natural gas. As part of a settlement with the owner of the reactor, the U.S. Department of Energy agreed to take title to the spent fuel in the ISFSI and obtain an NRC license for the facility. The license for the ISFSI was transferred to the DOE in June 1999. Day-to-day operations of the ISFSI are accomplished by the DOE's Maintenance and Operations contractor, Bechtel Babcock Wilcox Idaho (BBWI). BBWI also operates the Three Mile Island Unit 2 ISFSI in Idaho for the DOE. This paradigm for ISFSI operations has been highly successful and is expandable to additional ISFSIs that may come under the jurisdiction of the DOE. PMID:12555031

  9. Fort St. Vrain initial fuel loading and physics tests

    International Nuclear Information System (INIS)

    The full-power operating license for the Fort St. Vrain Nuclear Generation Station was issued by the AEC on December 21, 1973. Core loading was started on December 27, 1973, and the loading of the 2274 fuel and reflector elements was completed in 20 days. Initial criticality was achieved on January 31, 1974. The critical control rod position indicated an 0.003 Δk difference between the predicted and actual critical core configuration. Pulsed-neutron measurements were performed to obtain the shutdown margin with all control rods inserted, the shutdown margin with the highest worth control rod pairs removed, and the reactivity worth of the control rod groups removed in the normal sequence in the approach to critical. Following the initial criticality, measurements of the axial flux distribution were performed in several regions of the core. The cold zero power measurements were performed with air in the core so that personnel access to the core cavity was possible to permit placement of in-core instrumentation. After completion of the cold physics measurements, the special in-core instrumentation was removed and the primary system was sealed and filled with helium. Measurements of reactivity coefficients are scheduled to be performed as part of the hot physics testing. Additional physics tests are scheduled for the rise-to-power test program and include measurements of control rod worth, temperature coefficient, xenon reactivity, and xenon stability

  10. Fort St. Vrain fuel-handling system RAM analysis

    International Nuclear Information System (INIS)

    Public Service of Company of Colorado (PSC) is planning to decommission its Fort St. Vrain plant in 1990. This requires removal of 1,500 separate assemblies from the core. With the low historical availability of the fuel-handling system (FHS), defueling time was estimated at 36 months. With plant expenses of approximately $1.6 million per month during defueling, this would mean a schedule cost of $58 million. With their contractor, Rockwell International, PSC embarked on a reliability, availability, and maintainability (RAM) analysis to reduce projected defueling time. Key elements included (a) estimating availability of the FHS using a limited historical record, (b) assessing the defueling critical path, and (c) proposing and evaluating design/operational improvements. The most cost-effective improvements are being implemented and are expected to provide a reduction of >18 months in schedule and a net savings of $20 to 25 million. The paper describes the FHS design and operation, major problems associated with fuel-handling operations, and results and recommendations

    Habitat enhancement, protection and monitoring were the focus of the Resident Fisheries Program during 2008. Enhancement and protection included sloping, fencing and planting wetlands plugs at sites on Spring Creek (Head-waters). Many previously constructed instream structures (rock barbs and wing dams) were repaired throughout the Fort Hall Indian Reservation (Reservation). Physical sampling during 2008 included sediment and depth measurements (SADMS) in Spring Creek at the Car Removal site. SADMS, used to track changes in channel morphology and specifically track movements of silt through Bottoms stream systems were completed for 5 strata on Spring Creek. Water temperature and chemistry were monitored monthly on Spring Creek, Clear Creek, Diggie Creek, and Portneuf (Jimmy Drinks) and Blackfoot rivers. Fish population densities and biomass were sampled in five reservation streams which included nine sites. Sampling protocols were identical to methods used in past years. Numbers of fish in Spring Creek series remained relatively low, however, there was an increase of biomass overall since 1993. Salmonid fry densities were monitored near Broncho Bridge and were similar to 2006, and 2007, however, as in years past, high densities of macrophytes make it very difficult to see fry in addition to lack of field technicians. Mean catch rate by anglers on Bottoms streams stayed the same as 2007 at 1.5/hr. Numbers of fish larger than 18-inches caught by anglers increased from 2007 at .20 to .26/hr.

    Habitat enhancement and protection were the main focus of the Resident Fish Program during 1999. Biotic sampling included a genetic survey of salmonids on the Fort Hall Reservation. In addition, density and biomass of fish in select Bottoms streams was monitored. Enhancement and protection included anchoring 1,327 m of evergreen tree revetments and erecting three kilometers of enclosure fence. Physical sampling during 1999 included sediment and depth surveys and chemical measurements. Baseline SADM's, used to track changes in channel morphology and specifically track movements of silt through the system were completed for eight strata in Big Jimmy Creek. Numbers of fish in Clear creek were much lower than previous years. In addition, numbers of fry counted at Broncho Bridge were significantly lower than previous years. Future monitoring will determine whether low numbers are cyclic and related to weak year classes or low numbers are the result of anthropogenic influences. Permit fishing seasons continued to provide a source of income for the Tribes and an opportunity for non-tribal members to fish Bottoms streams. Mean catch rate by anglers on Bottoms streams increased from that of previous years to 1.02 fish per hour.

  14. Scottish vitrified forts: background and potential for TL dating

    International Nuclear Information System (INIS)

    Scottish vitrified forts have been the subject of considerable interest since their discovery in the late 18th century. This presentation deals with the nature of these sites, their archaeological, historical and technical backgrounds, the existing chronological evidence from 14C dates and the potential for thermoluminescence dating revealed by a short feasibility study. The dosimetric properties of a range of sites are evaluated in some detail using a combination of X-ray fluorescence analysis, neutron activation analysis, high resolution gamma ray spectrometry and on site NaI spectroscopy. Favourable conditions are encountered in many cases particularly for samples extracted from infinite gamma matrices using a diamond coring technique. The TL properties of quartz inclusions from such samples are discussed. In addition to examples showing conventional behaviour, some samples have exhibited severe supralinearity coupled to sensitisation which presents obstacles to dating. Tests for such 'malign' behaviour are proposed which will add to the reliability of TL dates from this type of sample. (author)

  15. Fracture mapping in the Soultz-sous-Forêts geothermal field using microearthquake locations

    Science.gov (United States)

    Michelet, Sophie; ToksöZ, M. Nafi

    2007-07-01

    In 2003, a massive hydraulic fracturing experiment was carried out at the European Geothermal Hot Dry Rock site at Soultz-sous-Forêts, France. The 2 week injection of water generated a high level of microseismic activity, triggering about 90,000 microearthquakes during and after the fluid injection. Of these, 21,000 events, detected at all stations, were located individually with a grid search algorithm to characterize the extent of the seismic zones and ultimately of the fracture network. The accuracy of these initial locations was around 70 m, not sufficient to map detailed fracture patterns. A precise relocation effort was undertaken to reduce the location uncertainties using three different techniques: joint hypocenter determination (JHD), collapsing and multiplet analysis. The collapsing method was added to the JHD results to further consolidate the hypocenters. On the other hand, a multiplet analysis was performed on the initial data set for identifying microearthquakes with similar waveforms and hence relocating relatively the correlated events. The delays in traveltime were computed by wavelet analysis and the events were relocated using a grid search algorithm. We found 7463 events whose seismograms correlated with a correlation coefficient of 0.8 or higher, most of which were doublets. Multiplets are horizontal tube-like structures with lengths from a hundred to several hundred meters striking along the direction of the maximum compressive horizontal stress. We interpret these structures as the preferential paths where fluid flow is largely confined. This hypothesis is reinforced by the good correlation in depth between the events and the fluid outflows observed in the well. Therefore we believe that these relocated events highlight the zones where the permeability of the reservoir is increased.

Contribution to the understanding of the behaviour of reinforced concrete shear walls under seismic loading: contribution of experiment and modeling to the design; Contribution a la comprehension du fonctionnement des voiles en beton arme sous sollicitation sismique: apport de l'experimentation et de la modelisation a la conception

    This thesis deals with aspects of seismic behaviour of reinforced concrete shear walls (RCSW). Its objective is to introduce a useful modelling approach for addressing the non-linear response of a large variety of RCSW and to identify several aspects in which this numerical approach could be implemented into design applications. Firstly, the characteristics of the behaviour of RCSW under seismic loading, some design principles and different modelling approaches are discussed. As an important lack of knowledge in several fields was identified, it was considered that three types of shear walls deserve more attention: slightly reinforced slender walls; U-shaped walls and heavily reinforced squat shear walls. A local modelling approach is adopted and the material constitutive models are described in details. Secondly, the behaviour of the two mock-up, CAMUS I and II, tested on the shaking-table during the CAMUS programme, which are slightly reinforced and designed according to the French code PS92 is simulated using a 2-D finite element model (FEM). For comparison purposes, the case of the CAMUS III mock-up, designed according to EC8, is considered. We are then dealing with the case of U-shaped walls under dynamic and cyclic loading. The results obtained from numerical simulations, based on a 3-D shell FEM, are compared with those obtained from tests carried out in the frame of the ICONS programme. Finally, the numerical model is applied to the case of heavily reinforced squat shear walls (similar to those used in the nuclear power plant buildings) subjected to shear loading. A 2-D FEM is considered in order to simulate the behaviour of three different walls, which were tested pseudo-dynamically during the SAFE programme. The results from both experimental and numerical studies are compared and discussed. The most important factors affecting the behaviour of RCSW are highlighted. Different examples of possible contributions to design are presented. (author)

    We propose a model describing the evolution of mechanical and permeability properties of concrete under slow mechanical loading. Calling upon the theory of continua with microstructure, the kinematic of the domain is enriched by a variable characterising size and orientation of the crack field. We call upon configurational forces to deal with crack propagation and we determine the balance equations governing both strain and propagation. The geometry of the microstructure is representative of the porous media: the permeability is obtained from the resolution of Stokes equations in an elementary volume. An example has been treated: we considered simple assumptions (uniform crack field, application of linear fracture mechanics...) and we determined the behaviour of a body under tensile loading. Strain, crack propagation and stiffness loss are completely assessed. Finally the evolution of permeability is plotted: once activated, crack propagation is the main cause of water tightness loss.

  3. Geodetic monitoring strategy at the geothermal sites of Soultz-sous-Forêts and Rittershoffen (Upper Rhine Graben, France)

    Heimlich, Christine; Masson, Frédéric; Gourmelen, Noël

    2014-05-01

    The European Cenozoic rift system, and in particular the Upper Rhine Graben offers a high potential of deep geothermal energy due to the well known geothermal anomaly and to the number of subsurface temperature data from oil exploration in the Upper Rhine Graben. One example is the Soultz-sous-Forêts Enhance Geothermal System (EGS) located in the French part of the Upper Rhine Graben. The Soultz-sous-Forêts EGS started in 1987 as a deep geothermal research site. The wells are drilled in naturally fractured and altered granites from 3200 to 5260 m depth located in the vicinity of quasi North-South faults. It is the first EGS site connected to the electric network, its electric production capacity is of 1.5MWe. A second EGS site, ECOGI, is in development near the village of Rittershoffen located at 7 km from Soultz-sous-Forêts. The objective of ECOGI is to produce 24MWth energy for an industrial use with a doublet configuration of wells at depths around 2500 and 3000 meters. Both EGS sites benefit of the natural circulation of geothermal water. Some challenges in geothermal power plant are to understand the long-term behavior of the geothermal system and the induced seismicity. In the Soultz-sous-Forêts plant, borehole measures give evidences of aseismic slip (Bailleux et al., 2013). And previous geodetic monitoring studies of other deep geothermal plants show subsidence and horizontal displacements due to geothermal exploitation (e.g. Massonnet et al., 1997; Nishijima et al., 2005; Fialko and Simons, 2000). The ability of geodesy tools to provide information about dynamic behaviour and the change in the local stress field around the geothermal site make them a suitable method to meet these challenges. Therefore, we establish a long-term geodetic monitoring system of the two geothermal sites. This work presents the monitoring strategy and the preliminary results. We install a network of continuous GNSS and INSAR data are in acquisition. Our aim is to monitor

  8. DSM/Federal energy efficiency partnership program at Fort Lewis, Washington

    International Nuclear Information System (INIS)

    The Energy Systems Modernization Office (ESMO) at Pacific Northwest Laboratory (PNL) is developing and applying the Federal Energy Decision Screening (FEDS) system for federal installations in cooperation with the servicing utility(s). The process involves five parts: assess installation-wide, fuel-blind energy-efficiency resource, identify the most life-cycle cost-effective technologies, work with the servicing utility to develop a program to implement energy conservation projects and technologies, evaluate rates and rate structures, and contribute to the design and implementation of an energy savings verification procedure to evaluate the impact of installed technologies. Fort Lewis, a large military installation in Tacoma, Washington, was identified as a site for a pilot program. Fort Lewis has an annual electric load of about 195,000 megawatt-hours (MWh)(-40 MW). An energy conservation supply curve was developed showing the amount of electric energy savings that can be achieved at different prices for energy saved. From these data, a proposal was prepared for acquiring approximately 43,000 kilowatt-hours (kWh) (-4 MW) of annual cost-effective electric energy savings, which TPU presented to Bonneville. This proposal identified investment requirements at the Fort and the likely energy and dollar savings. Approximately $10 million of investment in electrical energy efficient end-use technology was estimated to be cost-effective at Fort Lewis under this arrangement. In the agreement with Fort Lewis, TPU will finance 100% of this investment and will procure the energy services contractor who will conduct the detailed audits and install the technologies. The Fort will repay TAU 15% of the total installed cost of the technology over the time period of the installation of the technologies. The result is that Fort Lewis will see a reduction in its electric bill of approximately $500,000/year, depending on the final program design

  10. Faulting mechanisms and stress regime at the European HDR site of Soultz-sous-Forets, France

    International Nuclear Information System (INIS)

    The state of stress and its implications for shear on fault planes during fluid injection are crucial issues for the HDR (Hot Dry Rock) or EGS (Enhanced or Engineered Geothermal System) concept. This is especially true for hydraulic stimulation experiments, aimed at enhancing the connectivity of a borehole to the natural fracture network, since they tend to induce the shearing of fractures, which is controlled by the local stress regime. During the 2000 and 2003 stimulation tests at Soultz-sous-Forets, France, about 10,000 microearthquakes were located with a surface seismological network. Hundreds of double-couple (DC) focal mechanisms were automatically determined from first-motion polarities using the FPFIT program [Reasenberg, P.A., Oppenheimer, D., 1985. FPFIT, FPPLOT and FPPAGE: Fortran computer programs for calculating and displaying earthquake fault-plane solutions. US Geological Survey Open-File Report 85-739, 25 pp.]. The majority of these mechanisms indicate normal-faulting movement with a more or less pronounced strike-slip component. Some quasi-pure strike-slip events also occurred, especially in the deeper part of the stimulated rock volume, at more than 5 km depth. Although we found a double-couple solution for all events, we tried to observe and quantify the proportion of the non-double-couple (NDC) component in the seismic moment tensor for several microseisms from the 2003 data. The study shows that the NDC is higher for the events in the vicinity of the injection well than for the events far from the well. We used the method of Rivera and Cisternas [Rivera, L., Cisternas, A., 1990. Stress tensor and fault-plane solutions for a population of earthquakes. Bull. Seismol. Soc. Am. 80, 600-614.] to perform the inversion of the deviatoric part of the stress tensor from P-wave polarities. This method was applied to different datasets from the 2000 test, taken from the shallower and deeper parts of the stimulated region. The results show a stable

    The goal of this work was the study, development and optimization of hydrogenated amorphous silicon (a-Si:H) devices for use in detection of ionizing radiation. Thick p-i-n devices, capable of withstanding large electric fields (up to 10{sup 6} V/cm) with small currents (nA/cm{sup 2}), were developed. To decrease fabrication time, films were made using the `He diluted` PECVD process and compared to standard a-Si:H films. Aspects connected to specific detector applications as well as to the fundamental physics of a-Si:H were considered: the internal electric field technique, in which the depletion charge was measured as a function of the applied bias voltage; study of the leakage current of p-i-n devices permitted us to demonstrate different regimes: depletion, field-enhanced thermal generation and electronic injection across the p layer. The effect of the electric field on the thermal generation of the carriers was studied considering the Poole-Frenkel and tunneling mechanisms. A model was developed taking under consideration the statistics of the correlated states and electron-phonon coupling. The results suggest that mechanisms not included in the `standard model` of a Si:h need to be considered, such as defect relaxation, a filed-dependent mobility edge etc...; a new metastable phenomenon, induced by prolonged exposure to a strong electric field, was observed and studied. It is characterized by marked decrease of the leakage current and the detector noise, and increase in the breakdown voltage, as well as an improvement of carrier collection efficiency. This forming process appears to be principally due to an activation of the dopants in the p layer; finally, the capacity of thick p-i-n a Si:H devices to detect ionizing radiation has been evaluated. We show that it is possible, with 20-50 micron thick p-i-n devices, to detect the full spectrum of alpha and beta particles. With an appropriate converter, neutron detection then becomes possible.

    The reliability approach in power electronics is a complex problem including the coupling of current / voltage surges, physical and technological imperfections, from the die to the power circuit. First of all, we define a methodology based on the monitoring of a great number of components, during a long time campaign. Components are 600 V-50 A-20 kHz IGBT-diodes modules working in PWM inverter cells owing to an original opposition method. An exhaustive study of cell-switching failure modes allowed us to design a suitable and efficient protection. Afterwards, a complete reliability test bench was carried out with electrical and thermal monitoring. A preliminary screening protocol was also applied. The first results are presented in this thesis. (author)

  13. Habitat restoration/enhancement Fort Hall Reservation : 2001 annual report

    International Nuclear Information System (INIS)

    Habitat enhancement, protection and monitoring were the focus of the Resident Fisheries Program during 2001. Enhancement and protection included sloping, fencing and planting willows at sites on Diggie Creek, Clear Creek and Spring Creek. In addition, many previously constructed instream structures (rock barbs and wing dams) were repaired throughout the Fort Hall Indian Reservation (Reservation). In 2001, exclosure fences were erected on Diggie Creek (250 m barbed wire; (70 m jack), Wood Creek (500 m jack), Clear Creek (20 m jack), Ross Fork Creek (200 m jack), West Fork Creek (200 m jack)) and the Portneuf River (1 km barbed wire; 100 m jack). Jack and rail exclosure fences that had deteriorated over the past ten years were repaired at numerous areas throughout the Reservation. Physical sampling during 2001 included sediment and depth surveys (SADMS) in Big Jimmy Creek and Diggie Creek. SADMS, used to track changes in channel morphology and specifically track movements of silt through Bottoms stream systems were completed for eight and nine strata in the Big Jimmy and Diggie Creek, respectively. Baseline SADM data was collected in Diggie Creek to monitor the effects of bank sloping and revegetation on channel morphology and sediment levels through time. Water temperature was monitored (hourly) in Spring Creek, Clear Creek, Ross Fork Creek and Big Jimmy Creek. Biotic sampling included invertebrate sampling in the 200 and 300 series of Clear Creek. Fish population densities and biomass were sampled in Clear Creek 200 and 300 series. Sampling protocols were identical to methods used in past years. Numbers of fish in Clear Creek 300 series remained similar to 2000 while numbers of fish in Clear Creek 200 series dropped to near pre project levels. Salmonid fry densities were monitored near Broncho Bridge and were significantly higher than 2000. A mark-recapture study was initiated in spring 2001 to estimate numbers of spawning adults using the Head End of Spring Creek

The raw material (tambaqui fillets and the sous vide underwent physical, physicochemical, and microbiological analyses. A sauce was prepared containing soy sauce, water, horseradish and garlic flakes. The product's pasteurization parameters of time and temperature were defined according to a 22 central composite rotatable design (CCRD, and the dependent variables were water holding capacity (WHC and instrumental texture aiming at obtaining high WHC values for the product to maintain the desired juiciness. The microbiological analysis required by legislation have indicated that the fish fillets and sous vide were within de standard. The values of total coliforms found in the samples (fillets and sous vide analyzed were below the critical level of 10² CFU/g. The counts of sulphite-reducing clostridia and psychrotrophic and mesophilic bacteria on plates in the samples were <1x10 CFU/g. In conclusion, temperature was the most important factor in the pasteurization process, significantly contributing to the quality of the final product. The mathematical models proposed were considered predictive for each response.

    Full Text Available L’étude vise à analyser les déterminants du désir de grossesse chez les femmes séropositives sous traitement anti-retroviral, afin de contribuer à la réduction de la transmission du virus de la mère à l’enfant. Elle a pour objectifs spécifiques de déterminer la proportion des grossesses chez les femmes à sérologie VIH positive, d’évaluer l’attitude du personnel de santé à l’égard des messages à donner aux femmes séropositives sous ARVs en ce qui concerne le désir de la grossesse, et relever les facteurs déterminant le désir d’avoir des enfants après la mise ne route d’un traitement par antirétroviraux . Il s’agit d’une étude descriptive transversale. Elle a été conduite auprès de 260 femmes infectées par le VIH sous ARVs et suivies dans les FOSA, ayant les services de VCT/PMTCT et des ARVs. L’étude montre que 26,9% des femmes ont été enceintes après avoir été informées de leur statut sérologique positif pour le VIH et que 38,5% des femmes séropositives sous traitement anti-rétroviral désirent avoir des enfants dans le futur. La majorité des femmes (82,7% reconnaissent l’importance de l’utilisation des contraceptifs alors que le pourcentage des femmes qui connaissent l’importance d’utiliser les ARVs pendant la grossesse et l’accouchement pour réduire le risque de transmission de la mère à l’enfant est de 76,9%. Les facteurs déterminant le désir de la grossesse parmi les femmes séropositives sont : La confiance attribuée aux anti-rétroviraux, la parité c’est-à-dire les femmes qui n’ont pas eu d’enfant ont un désir de maternité deux fois supérieur que les femmes qui ont eu au moins un enfant, et la non utilisation des méthodes contraceptives chez les femmes à sérologie VIH positives pour réduire le risque de transmission de la mère à l’enfant. Nous recommandons de renforcer l’intégration des activités de santé de la reproduction et de Planning

    2006-10-15

    Circulation of geothermal fluids through granitic fractured reservoirs leads to chemical reactions, modifying the porosity and permeability of the rock mass. FRACHEM, a thermo-hydraulic-chemical coupled computer code, was developed specifically to predict changes in the geothermal reservoir of the Soultz-sous-Forets Enhanced Geothermal System (EGS) located in Alsace, France. This code can simulate fluid-rock interactions and determine the dissolution/precipitation reactions of eight minerals in the Soultz granite (i.e. carbonates, pyrite, silicates and aluminosilicates). Numerical simulation results of long-term fluid circulation through the 5000-m deep Soultz reservoir are comparable to those determined for the shallow reservoir and confirm the role played by carbonates in the evolution of reservoir porosity and permeability. Moreover, experiments with FRACHEM in simulating short-term fluid flow during hydraulic and/or chemical stimulations have demonstrated that the code could prove an efficient tool in reservoir engineering and management.

  6. Delayed progressive haematoma after Le Fort I osteotomy: A possible severe complication in orthognatic surgery

    Directory of Open Access Journals (Sweden)

    Dario Bertossi

    2012-01-01

    Full Text Available Although the Le Fort I osteotomy is a safe surgical technique, many complications have been reported. We present a case of an extended cervico-facial haematoma due to delayed bleeding from the terminal branches of the maxillary artery after orthognatic surgery. A 23-year-old man was referred to our observation for the surgical correction of a class III asymmetric malocclusion. The patient underwent a Le Fort I osteotomy, with impaction of the maxilla, associated with an Epker mandibular bilateral sagittal split osteotomy, with maxillary advancement and rigid internal fixation of the mandible with four miniplates and another four for the upper maxilla as well. The first post-surgery day, the patient developed a gradual dispnea together with neck swelling. By second postoperative day, the patient′s general condition improved with a progressive normalization of laboratory tests values. The Computerised Axial Tomography (CAT scan confirmed a decrease in the parapharyngeal thickening. Total recovery was achieved within two months, the final clinical check showed a healthy appearance with good occlusion. An increased knowledge of the basic biology of the Le Fort I osteotomy, the development of instruments specially designed for the Le Fort I procedure and the use of hypotensive anaesthesia could reduce the morbidity and duration of this procedure.

  9. Pictorial account and landscape evolution of the crevasses near Fort St. Philip, Louisiana

    Science.gov (United States)

    Suir, Glenn M.; Jones, William R.; Garber, Adrienne L.; Barras, John A.

    2014-01-01

    Quantifying the effects of active natural and constructed crevasses is critical to the planning and success of future ecosystem restoration activities. This document provides a historical overview of landscape changes within the vicinity of the natural crevasses near Fort St. Philip, Louisiana. A significant event influencing landscape change within the Fort St. Philip study area was the breaching of the eastern levee of the Mississippi River. Initially, the river water that was diverted through these crevasse channels physically removed significant marsh areas within the study area. These initial direct impacts were succeeded by several decades of larger regional loss patterns driven by subsidence and other episodic events (e.g, hurricanes and floods), and recent localized land gains. These increases in land area are potentially the long-term results of the Fort St. Philip crevasses, and the short-term impacts of delta management activities. However, for the majority of the 1956-2008 period of analysis, the crevassing of the eastern bank of the Mississippi River levee was a loss accelerant in the Fort St. Philip area.

  12. Third party testing : new pilot facility for mining processes opens in Fort McKay

    International Nuclear Information System (INIS)

    Fort McKay lies 65 kilometres north of Fort McMurray, Alberta and is the centre of operational oilsands mining activity. As such, it was chosen for a pilot testing facility created by the Geneva-based SGS Group. The reputable facility provides an opportunity for mining producers to advance their processes, including environmental performance, by allowing them to test different processes on their own oilsands. The Northern Lights partnership, led by Synenco Energy, was the first client at the facility. Due to outsourcing, clients are not obligated to make substantial capital investment into in-house research. The Northern Lights partnership will be using the facility to test extraction processes on bitumen from its leases. Although the Fort McKay facility is SGS's first venture into the oilsands industry, it operates in more than 140 companies globally, including the mineral industry, and specializes in inspection, verification, testing and certification. SGS took the experience from its minerals extraction business to identify what could be done to help the oilsands industry by using best practices developed from global operations. The facility lies on the Fort McKay industrial park owned by the Fort McKay First Nation. An existing testing facility called McMurray Resources Research and Testing was expanded by the SGS Group to include environmental analysis capabilities. The modular units that lie on 6 acres include refrigerated ore storage to maintain ore integrity; modular ore and materials handling systems; extraction equipment; and, zero discharge process water and waste disposal systems. Froth treatment will be added in the near future to cover the entire upstream side of the mining processing business. A micro-upgrader might be added in the future to manufacture synthetic crude. 3 figs

Des impulsions parasites a l'anode du photomultiplicateur sont produites par ces rayonnements. En comparant les amplitudes de ces impulsions a celles delivrees par un scintillateur NaI, on a constate que leur niveau maximal etait d'une centaine de keV a 10{sup 3} Rh{sup -1} dans le flux gamma du puits de stockage, et de 200 a 400 keV a 10{sup 3} Rh{sup -1} et 10{sup 7} n.cm{sup -2}.s{sup -1} dans le canal de pile. D'autre part, la detection d'une impulsion lumineuse de reference, correspondant a 200 keV (NaI) n'est perturbee qu'au dela de quelques centaines de Rh{sup -1} par le rayonnement {gamma} seul, et de 5. 10{sup 6} n.cm{sup -2} s{sup -1} et {approx}500 Rh{sup -1} dans le canal de pile. La dispersion de ces resultats est de l'ordre de 2 pour les 8 tubes eprouves. Nous attribuons a l'effet Cerenkov dans la fenetre du photomultiplicateur, la part principale des effets du rayonnement {gamma}. La discrimination des effets respectifs des neutrons et du rayonnement {gamma} est abordee. Nous n'avons pas constate d'evolution sensible des parametres des photomultiplicateurs etudies, pendant les expositions.

    2014-01-01

    Aeromagnetic data help provide the underpinnings of a hydrogeologic framework for Fort Irwin by locating inferred structural features or grain that influence groundwater flow. Magnetization boundaries defined by horizontal-gradient analyses coincide locally with Cenozoic faults and can be used to extend these faults beneath cover. These boundaries also highlight the structural grain within the crystalline rocks and may serve as a proxy for fracturing, an important source of permeability within the generally impermeable basement rocks, thus mapping potential groundwater pathways through and along the mountain ranges in the study area.

    2004-12-01

    Historically, the Fort Worth CHD has striven to provide the highest level of service toward the assurance of consumer safety. The burgeoning growth of the city, however, combined with limited resources, has challenged this capability. The response by CHD was to develop a long-term, orchestrated plan to not only maintain but also improve performance. To succeed, a multiyear, integrated plan to develop programming, personnel management, and budgeting was adopted. In accordance with this plan, the past five years have witnessed the cultivation and integration of strategic initiatives into a comprehensive and effective consumer safety program. The program has succeeded in improving inspections, lowering violation recidivism, maintaining compliance, and orchestrating activities to sustain improvements well into the future. CHD is proud of these accomplishments and of its service to the citizens of Fort Worth. In this spirit, CHD is happy to accept the 2004 Crumbine Award, which recognizes the dedication to consumer safety underlying this program. PMID:15628194

    Beginning June 14, the familiar bugle calls at Fort Detrick will be joined by a special percussion instrument: a cannon. A single cannon shot will be fired on the first note of “Reveille,” which signals the start of each day and is accompanied by the raising of the American flag. “Reveille” sounds at 6:30 a.m. At 5 p.m., Fort Detrick plays “Retreat,” which alerts the post that the flag is about to be lowered. The cannon will fire on the last note of “Retreat.” After a five-second pause, “To the Color” plays as the flag is lowered.

  2. A non-conventional procedure for the 3D modeling of WWI forts

    Science.gov (United States)

    Nocerino, E.; Fiorillo, F.; Minto, S.; Menna, F.; Remondino, F.

    2014-06-01

    2014 is the hundredth anniversary of the outbreak of the First World War (WWI) - or Great War - in Europe and a number of initiatives have been planned to commemorate the tragic event. Until 1918, the Italian Trentino - Alto Adige region was under the Austro - Hungarian Empire and represented one of the most crucial and bloody war front between the Austrian and Italian territories. The region borders were constellated of military fortresses, theatre of battles between the two opposite troops. Unfortunately, most of these military buildings are now ruined and their architectures can be hardly appreciated. The paper presents the initial results of the VAST project (VAlorizzazione Storia e Territorio - Valorization of History and Landscape), that aims to digitally reconstruct the forts located on the plateaus of Luserna, Lavarone and Folgaria. An integrated methodology has been adopted to collect and employ all possible source of information in order to derive precise and photo-realistic 3D digital representations of WWI forts.

    2008-01-01

    Military training, soil texture, and ground cover influence ant communities at Fort Benning, a military installation in west-central Georgia. We sampled 81,237 ground-dwelling ants (47 species in 20 genera) with pitfall traps at 40 sites on a continuum from nearly pristine forest to highly disturbed training areas. We also measured 15 environmental variables related to vegetation and soil. Sites disturbed by military training had fewer trees, less canopy cover, more bare ground, and more compact soils with shallower A-horizons than comparable undisturbed sites. Pheidole bicarinata, Dorymyrmex smithi, and Pogonomyrmex badius dominated the most highly disturbed sites. Competitively submissive myrmicines, such as Aphaenogaster and Crematogaster, and formicines, such as Camponotus and Formica, were abundant in the undisturbed sites. Solenopsis invicta occurred in all but the least disturbed sites. Ant community composition was a useful indicator of disturbance at Fort Benning.

    This paper discusses NRC approval for the first dry vault storage system to be submitted for nonsite specific design approval. It describes the first site specific application of the FW/GEC modular vault dry store (MVDS) for the Public Service of Colorado---Fort St. Vrain site. The decision to permanently shut down the Fort St. Vrain high temperature gas-cooled reactor provides the need to store on site 1,482 irradiated fuel blocks and a quantity of other reactor core components categorized as greater than Class C wastes. The MVDS system has been selected for the safe storage of these items in a facility designed to receive, store and discharge fuel to the repository totally independent from the original reactor facilities.

  5. Nondestructive examination of 51 fuel and reflector elements from Fort St. Vrain Core Segment 1

    International Nuclear Information System (INIS)

    Fifty-one fuel and reflector elements irradiated in core segment 1 of the Fort St. Vrain High-Temperature Gas-Cooled Reactor (HTGR) were inspected dimensionally and visually in the Hot Service Facility at Fort St. Vrain in July 1979. Time- and volume-averaged graphite temperatures for the examined fuel elements ranged from approx. 4000 to 7500C. Fast neutron fluences varied from approx. 0.3 x 1025 n/m2 to 1.0 x 1025 n/m2 (E > 29 fJ)/sub HTGR/. Nearly all of the examined elements shrank in both axial and radial dimensions. The measured data were compared with strain and bow predictions obtained from SURVEY/STRESS, a computer code that employs viscoelastic beam theory to calculate stresses and deformations in HTGR fuel elements

    2000-02-23

    In FY1999, Pacific Northwest National Laboratory conducted an energy efficiency campaign for residential housing at the Fort Lewis Army Installation near Tacoma, Washington. Preliminary weather-corrected calculations show energy savings of 10{percent} from FY98 for energy use in family housing. This exceeded the project's goal of 3{percent}. The work was funded by the U.S. DOEs Federal Energy Management Program (FEMP), Office of Energy Efficiency and Renewable Energy. The project adapted FEMP's national ``You Have the Power Campaign'' at the local level, tailoring it to the military culture. The applied research project was designed to demonstrate the feasibility of tailored, research-based strategies to promote energy conservation in military family housing. In contrast to many energy efficiency efforts, the campaign focused entirely on actions residents could take in their own homes, as opposed to technology or housing upgrades. Behavioral change was targeted because residents do not pay their own utility bills; thus other motivations must drive personal energy conservation. This campaign augments ongoing energy savings from housing upgrades carried out by Fort Lewis. The campaign ran from September 1998 through August 1999. The campaign strategy was developed based on findings from previous research and on input from residents and officials at Fort Lewis. Energy use, corrected to account for weather differences, was compared with the previous year's use. Survey responses from 377 of Fort Lewis residents of occupied housing showed that the campaign was moderately effective in promoting behavior change. Of those who were aware of the campaign, almost all said they were now doing one or more energy-efficient things that they had not done before. Most people were motivated by the desire to do the right thing and to set a good example for their children. They were less motivated by other factors.

  13. Fort Lewis natural gas and fuel oil energy baseline and efficiency resource assessment

    International Nuclear Information System (INIS)

    The mission of the US Department of Energy (DOE) Federal Energy Management Program (FEMP) is to lead the improvement of energy efficiency and fuel flexibility within the federal sector. Through the Pacific Northwest Laboratory (PNL), FEMP is developing a fuel-neutral approach for identifying, evaluating, and acquiring all cost-effective energy projects at federal installations; this procedure is entitled the Federal Energy Decision Screening (FEDS) system. Through a cooperative program between FEMP and the Army Forces Command (FORSCOM) for providing technical assistance to FORSCOM installations, PNL has been working with the Fort Lewis Army installation to develop the FEDS procedure. The natural gas and fuel oil assessment contained in this report was preceded with an assessment of electric energy usage that was used to implement a cofunded program between Fort Lewis and Tacoma Public Utilities to improve the efficiency of the Fort's electric-energy-using systems. This report extends the assessment procedure to the systems using natural gas and fuel oil to provide a baseline of consumption and an estimate of the energy-efficiency potential that exists for these two fuel types at Fort Lewis. The baseline is essential to segment the end uses that are targets for broad-based efficiency improvement programs. The estimated fossil-fuel efficiency resources are estimates of the available quantities of conservation for natural gas, fuel oils number-sign 2 and number-sign 6, and fuel-switching opportunities by level of cost-effectiveness. The intent of the baseline and efficiency resource estimates is to identify the major efficiency resource opportunities and not to identify all possible opportunities; however, areas of additional opportunity are noted to encourage further effort

    The nuclear power plant at Fort St. Vrain, with the world's only operating HTR, reached full-load operation on November 6, 1981. Operating tests at full load were carried out for three days, i.e. until November 9. The power plant was then shut down for maintenance and for reconstruction of the helium compressor auxiliary system. All HTR components and systems worked reliably during full-load operation. The trial operation has helped to advance commercial HTR technology. (orig.)

    Hadley, D.L.; Stucky, D.J.

    1995-03-01

    The Pacific Northwest Laboratory (PNL) evaluated heating and cooling system options for existing family housing at Fort Irwin, California. The purpose of this work was to quantify the energy conservation potential of alternative system types and to identify the most cost-effective technology available. The conventional residential heating/cooling systems at Fort Irwin are separate propane forced-air furnaces and central air conditioners. The options examined included air- and ground-source heat pumps, a natural gas furnace with central air conditioning, and a natural-gas-fired heat pump. The most cost-effective technology applicable to Fort Irwin was found to be the high-efficiency ground-source heat pumps. If all conventional units were replaced immediately, the net energy savings would be 76,660 MBtu (80.9 TJ) per year and a reduction in electrical demand of approximately 15,000 kW-month. The initial investment for implementing this technology would be approximately $7.1 million, with a savings-to-investment ratio of 1.74.

    The aim of this study was to evaluate the maxillary stability in patients who had undergone Le Fort I osteotomy with propeller graft and mandibular sagittal split ramus osteotomy for correction of maxillary asymmetry. This was a retrospective study on 15 facial asymmetry patients (7 men, 8 women: 22.2 years) requiring surgical correction at the preoperative (T0), immediately postoperative (T1) and 6 months after surgery (T2) stages. To evaluate the skeletal stability, computed tomography (CT) superimposition was used, and skeletal landmarks were measured and compared from the superimposed images according to an x, y, z coordinate system. The skeletal changes at each stage (ΔT1-T0 and ΔT2-T1) were compared by paired t-test (P<0.05). The obtained data on the skeletal changes immediately postoperatively to 6-month follow-up (ΔT2-T1) showed that the Le Fort I osteotomy with propeller graft had effected stable maxillary skeletal stability at the maxillary measurement points (posterior nasal spine (PNS ), nasopalatine canal, U3 crown tip, U3 root apex, and U6 furcation). These results suggested that in cases of facial asymmetry where the upper tooth exposure is proper and anterior-posterior movement of the maxilla is not much required, Le Fort I osteotomy with propeller graft is an effective method for stable canting correction.

  1. How confident is Fort McKay that industry can reclaim oil sand development

    International Nuclear Information System (INIS)

    This presentation described how traditional environmental knowledge (TEK) can provide valuable information for both the reclamation design and assessment of oil sand development in Fort McKay. Conservation is valued by the Fort McKay First Nations communities who claim that current reclamation methods are too slow, and that the land is not being brought back to its original use with the uniqueness of the boreal landscape. Elders have noted that each year the water level in the Athabasca River is lower. The blowing tailings and coke dust are causing trees to dye and driving animals away. There is concern that the animals that remain may not be safe to eat. The Fort McKay First Nation community has stated that it will view reclamation as a success only when it functions with proof over many generations. The major concerns include: salt in the water draining from reclaimed areas; salt in the soils of reclaimed area; muskeg cannot be recreated; and, the issue of whether cranberry, blueberry and streambank forest areas can be recreated, along with traditional medicinal plants. Other concerns include the loss of rivers such as the Beaver Creek and Tar River, and that the water in reclaimed areas may not be suitable for animals to live in or to drink. tabs., figs

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) takes a look at the activities carried out during the period from April 2004 up to May 2009 at Soultz-sous-Forets, France, in connection with the enhanced geothermal systems (EGS) at that location. The report describes the work performed by the Swiss EGS Research and Development group involved in the Soultz project. The principal target set was to install and operate a power plant, enabling the deep reservoir/heat exchanger to be operated, evaluated and improved under realistic conditions. The Swiss contributors have been participating in several work packages: Short and long term tests and medium-term tests of the three-well reservoir/heat exchanger system, development and up-scaling, technical and economic design of larger, industrial, EGS units and the development of stimulation methodology for EGS. The exchange of findings obtained during this project phase is discussed, as is the state-of-the-art of EGS stimulation methods, the interpretation of logging data. Also, seismic /-hydraulic factors, the evaluation of the production/injection performance of the boreholes and reservoir development strategies are discussed as are the modelling of geochemical impact of forced fluid circulation in the deep geothermal reservoir and the results of chemical stimulation tests performed on site.

    1996-07-01

    An exhaustive analysis of 3000 macroscopic fractures encountered in the geothermal Hot Dry Rock borehole, EPS-1, located inside the Rhine graben (Soultz-sous-Foreˆts, France), was done on a continuous core section over a depth interval from 1420 to 2230 m: 97% of the macroscopic structures were successfully reorientated with a good degree of confidence by comparison between core and acoustic borehole imagery. Detailed structural analysis of the fracture population indicates that fractures are grouped in two principal fractures sets striking N005 and N170 °, and dipping 70 °W and 70 °E, respectively. This average attitude is closely related to the past tectonic rifting activity of the graben during the Tertiary, and is consistent with data obtained from nearby boreholes and from neighbouring crystalline outcrops. Fractures are distributed in clusters of hydrothermally altered and fractured zones. They constitute a complex network of fault strands dominated by N-S trends, except within some of the most fractured depth intervals (1650 m, 2170 m), where an E-W-striking fracture set occurs. The geometry of the pre-existing fracture system strikes in a direction nearly parallel to the maximum horizontal stress. In this favorable situation, hydraulic injections will tend both to reactivate natural fractures at low pressures, and to create a geothermal reservoir.

  4. Impacts of prescribed fire on ecosystem C and N cycles at Fort Benning Installation, Georgia

    A critical challenge for the land managers at military installation is to maintain the ecological sustainability of natural resources while meeting the needs of military training. Prescribed ground fire as a land management practice has been used to remove the ground layer plants at Fort Benning for two purposes: to facilitate access for military training, and to maintain and restore fire-adapted longleaf pine communities that are critical habitat for the federally endangered red-cockaded woodpecker (Picoides borealis). Nevertheless, the impacts of prescribed fire on ecosystem processes and health are not well-understood and quantified at the plot to regional scales. Frequent fire may result in ecosystem nitrogen (N) deficiency due to repeated N loss through combustion, volatilization, and leaching, threatening ecosystem sustainability at Fort Benning. On the other hand, N loss may be offset by enhanced symbiotic N2 fixation since fire favors herbaceous legumes by scarifying legume seeds and stimulating germination. Quantifying the impacts of prescribed fire on ecosystem carbon (C) and N cycles is further complicated by interactions and feedbacks among burning, nitrogen inputs, other land use practices (e.g. tree thinning or clear-cutting), and soil properties. In this study, we used the Erosion-Deposition-Carbon Model (EDCM), a process-based biogeochemical model, to simulate C and N dynamic at Fort Benning under different combinations of fire frequency, fire intensity, nitrogen deposition, legume nitrogen input, forest harvesting, and soil sand content. Model simulations indicated that prescribed fire led to nitrogen losses from ecosystems at Fort Benning, especially with high intensity and high frequency fires. Forest harvesting further intensified ecosystem nitrogen limitation, leading to reduced biophysical potential of C sequestration. The adverse impacts of prescribed fire and forest harvesting on C and N cycles were much higher in more sandy soil than in

  6. Why the seismicity induced in Soultz-sous-Forêts and Gross Schoenebeck enhanced geothermal fields are so different? (Invited)

    Science.gov (United States)

    Gaucher, E.; Kohl, T.

    2013-12-01

    In enhanced geothermal systems, hydraulic fracturing and hydraulic stimulation are techniques used to increase the reservoir permeability. Their secondary effect, the induced seismicity, is a unique means to image the fault network created or reactivated by the operations. The interpretation of the results for this latter application is however limited by the capabilities of the seismic network and by our understanding of the involved physical processes. Here, we propose to highlight systematic behaviors of the seismicity induced in enhanced geothermal reservoirs. This is performed through the analysis of two EGS sites which appear to behave very differently in terms of induced seismicity: the Soultz-sous-Forêts (France) and the Gross Schoenebeck (Germany) fields. Several physics-based models have been tested for these fields and these observations should be used to calibrate them and the underlying physical assumptions. The Soultz-sous-Forêts (France) geothermal field is located in the Upper Rhine valley. Over the development of this EGS, four wells have been drilled into the granitic basement, up to 5 km depth, and eight major stimulations were carried out to create the heat exchanger. Several major observations based on the large induced seismicity database have been made and can apply on other EGS. Hence, it was noticed that a) the induced seismicity mainly occurs along planar features, b) during stimulation, the induced seismicity becomes stronger over time and this is still observed after shut-in. Most often, the largest magnitude microearthquake occurs following shut-in, c) over a certain overpressure threshold, seismicity can be induced and also a clear Kaiser effect can be observed for already stimulated volumes, d) the stimulation and the circulation periods induce different seismic responses.

Une attention particuliere est accordee aux equations de la theorie semi-classique du transport et leur validite est verifiee. La procedure experimentale et les materiaux utilises pour concevoir les montages de mesures sont expliques en detail. Enfin, un chapitre est dedie a l'explication et l'interpretation des resultats de transport thermoelectrique sur YBa2Cu3O6+delta publies au cours de l'hiver 2010 dans les revues Nature et Physical Review Letters. Les donnees d'effet Seebeck dans les echantillons de La 1.8-x,Eu0.2SrxCuO 4, ou un changement de signe est observe, permettent de conclure a la presence d'une poche d'electrons dans la surface de Fermi qui domine le transport a basse temperature dans la region sous-dopee du diagramme de phase. Cette conclusion est similaire a celle obtenue par des mesures d'effet Hall dans YBa 2Cu3O6+delta et elle cadre bien dans un scenario de reconstruction de la surface de Fermi. Les donnees d'effet Nernst recueillies indiquent que la contribution des fluctuations supraconductrices est limitee a un modeste intervalle de temperature au-dessus de la temperature critique.

    Full Text Available Le débat sur la mixité scolaire, appelée coéducation, indissociable de l'enseignement féminin et des droits des femmes, fut largement ouvert en Espagne sous la Seconde République (1931-1936. Nous traiterons de l’état des mentalités quant à l’éducation des filles au travers de trois exemples d’opinion : Mirguet, Sarabia, Mihura. Ces exemples illustrent des tendances opposées à la coéducation, pour des raisons religieuse, morale ou réactionnaire, du fait même que l'éducation des filles reste un monde à part. Malgré toutes les propositions pour établir un programme scolaire et éducatif pour les jeunes filles, il ressort que paradoxalement les auteurs, d'idéologie ou de nationalité différentes ou dont les objectifs diffèrent, se recoupent de manière significative : l'éducation est une adéquation de la femme à son milieu et à son rôle et statut traditionnels.The debate on co-education, inevitably linked with the education of girls and women’s rights, was wide-ranging during the Spanish Second Republic (1931-1936. Attitudes towards girls’ education will be examined by looking at three examples of opinion: Mirguet, Sarabia and Mihura. These examples illustrate opposing points of view on co-education, based on religious, moral or reactionary grounds, since girls’ education remained a world apart. In spite of proposals to establish a school curriculum for young girls, paradoxically, the authors, with differeing ideologies, nationalities and aims, are significantly similar: education for girls should develop a harmonious link between girls’ background, and their traditional role and status.

  9. The hill forts and castle mounds in Lithuania: interaction between geodiversity and human-shaped landscape

    2015-04-01

    Lithuania is famous for its abundant, picturesque hill forts and castle mounds of natural origin. In Lithuania as well as in whole Europe the fortified hills were used as the society dwelling place since the beginning of the Late Bronze Age. Their importance increased when Livonian and Teutonic Orders directed a series of military campaigns against Lithuania with the aim of expansion of Christianity in the region at the end of 1st millennium AD, and they were intensively used till the beginning of the 15th c. when most of them were burned down during fights with the Orders or just abandoned due to the changing political and economical situation. What types of the geodiversity were used for fortified dwellings? The choice in a particular area depended on a variety of geomorphology left behind the retreating ice sheets. High spots dominating their surroundings were of prime interest. In E and SE Lithuania, the Baltic Upland hills marking the eastern margin of the last Weichselian glacier hosted numerous fortified settlements from the end of 2nd millennium BC to the Medieval Ages (Narkunai, Velikuskes etc). In W Lithuania, plateau-like hills of the insular Samogitian Upland had been repeatedly fortified from the beginning of 1st millennium AD to the 14th century (Satrija, Medvegalis etc). Chains of hill forts and castle mounds feature the slopes of glaciofluvial valleys of Nemunas, Neris and other rivers where the slopes were dissected by affluent rivulets and ravines and transformed into isolated, well protected hills (Kernave, Punia, Veliuona etc). Peninsulas and headlands formed by the erosion of fluvial and lacustrine deposits were used in the lowlands, e.g. in central and N Lithuania (Paberze, Mezotne etc). How much the landscape was modified for defense purposes? Long-term erosion and overgrowing vegetation damaged the former fortified sites, however some remains and the archeological excavations allowed their reconstruction.

    The need for affordable energy sources is acute in rural communities of Alaska where costly diesel fuel must be delivered by barge or plane for power generation. Additionally, the transport, transfer, and storage of fuel pose great difficulty in these regions. Although small-scale energy development in remote Arctic locations presents unique challenges, identifying and developing economic, local sources of energy remains a high priority for state and local government. Many areas in rural Alaska contain widespread coal resources that may contain significant amounts of coalbed methane (CBM) that, when extracted, could be used for power generation. However, in many of these areas, little is known concerning the properties that control CBM occurrence and production, including coal bed geometry, coalbed gas content and saturation, reservoir permeability and pressure, and water chemistry. Therefore, drilling and testing to collect these data are required to accurately assess the viability of CBM as a potential energy source in most locations. In 2004, the U.S. Geological Survey (USGS) and Bureau of Land Management (BLM), in cooperation with the U.S. Department of Energy (DOE), the Alaska Department of Geological and Geophysical Surveys (DGGS), the University of Alaska Fairbanks (UAF), the Doyon Native Corporation, and the village of Fort Yukon, organized and funded the drilling of a well at Fort Yukon, Alaska to test coal beds for CBM developmental potential. Fort Yukon is a town of about 600 people and is composed mostly of Gwich'in Athabascan Native Americans. It is located near the center of the Yukon Flats Basin, approximately 145 mi northeast of Fairbanks.

  11. ASSESSMENT OF HYDROCARBON SEEPAGE DETECTION METHODS ON THE FORT PECK RESERVATION, NORTHEAST MONTANA

    Energy Technology Data Exchange (ETDEWEB)

    Lawrence M. Monson

    2003-06-30

    Surface exploration techniques have been employed in separate study areas on the Fort Peck Reservation in northeastern Montana. Anomalies associated with hydrocarbon seepage are documented in all three areas and a variety of surface exploration techniques can be compared. In a small area with established production, Head Gas and Thermal Desorption methods best match production; other methods also map depletion. In a moderate-size area that has prospects defined by 3D seismic data, Head Gas along with Microbial, Iodine, and Eh soil anomalies are all associated with the best hydrocarbon prospect. In a large area that contains many curvilinear patterns observed on Landsat images, that could represent micro-seepage chimneys, results are inconclusive. Reconnaissance mapping using Magnetic Susceptibility has identified a potential prospect; subsequent Soil Gas and Head Gas surveys suggest hydrocarbon potential. In the final year of this project the principle contractor, the Fort Peck Tribes, completed a second survey in the Wicape 3D Seismic Prospect Area (also known as Area 6 in Phase I of the project) and sampled several Landsat image features contained in the Smoke Creek Aeromag Anomaly Area (also known as Area 1 in Phase II of the project). Methods determined to be most useful in Phases I and II, were employed in this final Phase III of the study. The Southwest Wicape seismic anomaly was only partially confirmed. The abundant curvilinears proposed to be possible hydrocarbon micro-seepage chimneys in the Smoke Creek Area were not conclusively verified as such. Insufficient sampling of background data precludes affirmative identification of these mostly topographic Landsat features as gas induced soil and vegetation anomalies. However relatively higher light gas concentrations were found associated with some of the curvilinears. Based on the findings of this work the Assiniboine & Sioux Tribes of the Fort Peck Reservation intend to utilize surface hydrocarbon

    This open, multicenter study investigated the tolerability and efficacy of a new tablet formulation of Echinacea purpurea extract (Echinaforce Forte; A. Vogel, Bioforce AG, Roggwil, Switzerland) in 80 subjects actively involved in sports. Most investigators (97.5%) rated the treatment as having "very good" or "good" tolerability. About 75% of patients and investigators rated its efficacy during a common cold as "very good" or "good," and 71% of subjects were free of cold episodes. This study is the first to suggest that Echinaforce is effective in the prophylaxis, as well as the treatment, of the common cold in persons who actively participate in sports. PMID:17142219

    In 1949, a radiometric traverse was made of rocks exposed along the banks of and near the Yukon River about Fort Yukon to Ruby, Alaska. Granitic rocks of Tertiary age and of Devonian or Carboniferous age and sandstone beds of Cretaceous age gave the highest readings obtained in the field. Other rock types examined were greenstone of Devonian or Carboniferous age and metamorphic rocks of Devonian and pre-Devonian age, sedimentary rocks, and liginite of Tertiary age, and alluvial deposits of Quaternary age. The most radioactive sample, from Melozitna River canyon, contained only 0.017 percent equivalent uranium.

    Menke, Chad D.; Kim, Moon H.; Fowler, Kathleen K.

    2012-01-01

    Digital flood-inundation maps for a 9-mile reach of the St. Marys River that extends from South Anthony Boulevard to Main Street at Fort Wayne, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the City of Fort Wayne. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site, depict estimates of the areal extent of flooding corresponding to selected water levels (stages) at the USGS streamgage 04182000 St. Marys River near Fort Wayne, Ind. Current conditions at the USGS streamgages in Indiana may be obtained from the National Water Information System: Web Interface. In addition, the information has been provided to the National Weather Service (NWS) for incorporation into their Advanced Hydrologic Prediction Service (AHPS) flood warning system. The NWS forecasts flood hydrographs at many places that are often collocated at USGS streamgages. That forecasted peak-stage information, also available on the Internet, may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. In this study, water-surface profiles were simulated for the stream reach by means of a hydraulic one-dimensional step-backwater model. The model was calibrated using the most current stage-discharge relation at the USGS streamgage 04182000 St. Marys River near Fort Wayne, Ind. The hydraulic model was then used to simulate 11 water-surface profiles for flood stages at 1-ft intervals referenced to the streamgage datum and ranging from bankfull to approximately the highest recorded water level at the streamgage. The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from Light Detection and Ranging (LiDAR) data) in order to delineate the area flooded at each water level. A flood inundation map was generated for each water-surface profile stage (11 maps in all) so that for any given flood stage users will be

  20. Initial operating experience at the Fort St. Vrain high-temperature reactor. Pt. 5

    International Nuclear Information System (INIS)

    During the start-up test programme, the Fort St. Vrain plant control systems and safety control systems have been tested and adjusted to the operating requirements. So far, they have worked satisfactorily in the range up to 10% of the rated power in fully automatic operation. Experiments and some actual incidents have shown that the control function is satisfactory in case of turbine failure, reactor scram, and coolant loop insulation failure. Transient states in normal operation, e.g. changes of load, are controlled with negligible deviations from the rated values. (orig./GL)

  1. The Fort St. Vrain high temperature gas-cooled reactor. Pt. 10

    International Nuclear Information System (INIS)

    In October 1977, during the rise to power test program, the Fort St. Vrain high temperature gas-cooled reactor experienced the first of 37 fluctuation events involving primary coolant outlet temperature, nuclear detector signals, steam generator module gas inlet temperature and steam generator module main and reheat steam temperatures. In a 3 year investigation it was determined that the apparent cause of the fluctuations was movements of core components accompanied by periodic changes in bypass flows and crossflows of primary coolant helium. Installation of region constraint devices has eliminated fluctuations, but a single small primary coolant helium core outlet temperature redistribution is experienced routinely during rise to power.

  2. The Fort St. Vrain high temperature gas-cooled reactor. II

    International Nuclear Information System (INIS)

    In field tests in a fossil-fueled facility, performed concurrently with Fort St. Vrain's construction, data indicated that the helium circulator design was well suited to provide primary coolant circulation for the high temperature gas-cooled reactor. After plant installation, primarily during the hot functional tests, a number of time-consuming delays developed caused by cavitation damage on circular speed valves, cavitation and fatigue damage on auxiliary water turbine buckets, water turbine nozzle erosion, static shutdown seal cracks and circulator primary closure helium leakage. After extensive analysis and testing, all of these problems were corrected. Circulators have performed satisfactorily at levels up to 70% of rated power. (Auth.)

    The purpose of the tests described is to show that the dynamic performance of the Fort St. Vrain helium circulator auxiliary systems satisfies all the guidelines and criteria established and agreed to by Public Service Company of Colorado (PSC), Proto-Power, and General Atomic Company (GA). Specifically, it is shown that transfers to and from backup bearing water and helium purification system transients do not cause any circulator trips. Furthermore, at PSC's request, in an effort to resolve any NFSC questions concerning these systems, the satisfactory repeatability of their dynamic performance is shown beyond any doubt.

  5. Revised Geologic Map of the Fort Garland Quadrangle, Costilla County, Colorado

    Science.gov (United States)

    Wallace, Alan R.; Machette, Michael N.

    2008-01-01

    The map area includes Fort Garland, Colo., and the surrounding area, which is primarily rural. Fort Garland was established in 1858 to protect settlers in the San Luis Valley, then part of the Territory of New Mexico. East of the town are the Garland mesas (basalt-covered tablelands), which are uplifted as horsts with the Central Sangre de Cristo fault zone. The map also includes the northern part of the Culebra graben, a deep structural basin that extends from south of San Luis (as the Sanchez graben) to near Blanca, about 8 km west of Fort Garland. The oldest rocks exposed in the map area are early Proterozic basement rocks (granites in Ikes Creek block) that occupy an intermediate structural position between the strongly uplifted Blanca Peak block and the Culebra graben. The basement rocks are overlain by Oligocene volcanic and volcaniclastic rocks of unknown origin. The volcanic rocks were buried by a thick sequence of basin-fill deposits of the Santa Fe Group as the Rio Grande rift formed about 25 million years ago. The Servilleta Basalt, a regional series of 3.7?4.8 Ma old flood basalts, was deposited within sediment, and locally provides a basis for dividing the group into upper and lower parts. Landslide deposits and colluvium that rest on sediments of the Santa Fe Group cover the steep margins of the mesas. Exposures of the sediment beneath the basalt and within the low foothills east of the Central Sangre de Cristo fault zone are comprised of siltstones, sandstones, and minor fluvial conglomerates. Most of the low ground surrounding the mesas and in the graben is covered by surficial deposits of Quaternary age. The alluvial deposits are subdivided into three Pleistocene-age units and three Holocene-age units. The oldest Pleistocene gravel (unit Qao) is preserved as isolated remnants that cap high surfaces north and east of Fort Garland. The primary geologic hazards in the map area are from earthquakes, landslides, and localized flooding. The Central

  10. Primary coolant chemistry of the Peach Bottom and Fort St. Vrain high temperature gas-cooled reactors

    International Nuclear Information System (INIS)

    The chemical impurities in the primary coolants of the Peach Bottom and Fort St. Vrain reactors are discussed. The impurity mixtures in the two plants were quite different because the sources of the impurities were different. In the Peach Bottom reactor, the impurities were dominated by H2 and CH4, which are decomposition products of oil. In the Fort St. Vrain reactor, there were high levels of CO, CO2, and H2O. Although oil ingress at Peach Bottom created carbon deposits on virtually all surfaces, its effect on reactor operation was negligible. Slow outgassing of water from the thermal insulation at Fort St. Vrain caused delays in reactor startup. The overall graphite oxidation in both plants was negligible. (author)

    A geophysical investigation was carried out to locate and characterize the remains of the Sancti Spiritus Fort, the first European settlement in the South Cone of America (1527-1529). In an initial stage, we used three complementary methods, ground penetrating radar, multifrequency electromagnetic induction and dipole-dipole electric profiling, to increase the possibility of detecting the structures of the Fort whose physical properties were expected to be similar to those of the surrounding soil, as they were constructed with raw earth probably extracted from it. From different views of the data, a number of electromagnetic signals apparently related to these structures were identified. Test excavations confirmed these hypotheses and showed that the structures were poorly preserved. Furthermore, they were almost indistinguishable through direct inspection of the excavated sections of soil, and very difficult to track. Therefore, in a second stage of geophysical studies, we acquired high-density grids of GPR data at relevant areas, looking for more detailed information about the structures. The results of these studies allowed to determine with precision their continuity through the site and also to interpret a number of areas which had remained unclear from the first survey. Extensive archaeological excavations were designed from the geophysical maps and carried out. From them, the geophysical interpretations were fully confirmed, and the presence of structural elements of previous and later native settlements was established.

  13. Preliminary assessment report for National Guard Training Center, Georgia Army National Guard, Fort Stewart, Georgia

    International Nuclear Information System (INIS)

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Georgia Army National Guard (GAARNG) facility near Hinesville, Georgia, known as the National Guard Training Center (NGTC). Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing preremedial activities and to provide a priority basis for completing corrective actions (where necessary) in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining previous site activities, types and quantities of hazardous substances utilized, and potential pathways by which contamination could affect public health and the environment. The scope of this assessment is limited to the facilities and past activities contained within the NGTC. Preliminary assessment site score sheet information is also provided for the NGTC. However, this assessment report is intended to be read in conjunction with a previous IRP assessment of Fort Stewart completed in 1992 (USATHAMA 1992) and to provide comprehensive information on the NGTC area for incorporation with information contained in that previous assessment for the entirety of Fort Stewart

    We examined home range behavior of female feral pigs (Sus scrofa) in a heavily hunted population on Fort Benning Military Reservation in west-central Georgia, USA. We used Global Positioning System location data from 24 individuals representing 18 sounders (i.e., F social groups) combined with markrecapture and camera-trap data to evaluate evidence of territorial behavior at the individual and sounder levels. Through a manipulative experiment, we examined evidence for an inverse relationship between population density and home range size that would be expected for territorial animals. Pigs from the same sounder had extensive home range overlap and did not have exclusive core areas. Sounders had nearly exclusive home ranges and had completely exclusive core areas, suggesting that female feral pigs on Fort Benning were territorial at the sounder level but not at the individual level. Lethal removal maintained stable densities of pigs in our treatment area, whereas density increased in our control area; territory size in the 2 areas was weakly and inversely related to density of pigs. Territorial behavior in feral pigs could influence population density by limiting access to reproductive space. Removal strategies that 1) match distribution of removal efforts to distribution of territories, 2) remove entire sounders instead of individuals, and 3) focus efforts where high-quality food resources strongly influence territorial behaviors may be best for long-term control of feral pigs.

    The U.S. Army Forces Command (FORSCOM) has tasked the U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP), supported by the Pacific Northwest Laboratory, to identify, evaluate, and assist in acquiring all cost-effective energy projects at Fort Irwin. This is part of a model program that PNL is designing to support energy-use decisions in the federal sector. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at the FORSCOM Fort Irwin facility located near Barstow, California. It is a companion report to Volume 1, Executive Summary, and Volume 2, Baseline Detail. The results of the analyses of EROs are presented in 16 common energy end-use categories (e.g., boilers and furnaces, service hot water, and building lighting). A narrative description of each ERO is provided, along with a table detailing information on the installed cost, energy and dollar savings; impacts on operations and maintenance (O&M); and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. A description of the evaluation methodologies and technical and cost assumptions is also provided for each ERO. Summary tables present the cost-effectiveness of energy end-use equipment before and after the implementation of each ERO and present the results of the life-cycle cost (LCC) analysis indicating the net present valve (NPV) and savings-to-investment ratio (SIR) of each ERO.

    2014-01-01

    Recent analyses suggest that the big brown bat (Eptesicus fuscus) may be less of a beetle specialist (Coleoptera) in the western United States than previously thought, and that its diet might also vary with temperature. We tested the hypothesis that big brown bats might opportunistically prey on moths by analyzing insect fragments in guano pellets from 30 individual bats (27 females and 3 males) captured while foraging in Fort Collins, Colorado, during May, late July–early August, and late September 2002. We found that bats sampled 17–20 May (n = 12 bats) had a high (81–83%) percentage of volume of lepidopterans in guano, with the remainder (17–19% volume) dipterans and no coleopterans. From 28 May–9 August (n = 17 bats) coleopterans dominated (74–98% volume). On 20 September (n = 1 bat) lepidopterans were 99% of volume in guano. Migratory miller moths (Euxoa auxiliaris) were unusually abundant in Fort Collins in spring and autumn of 2002 and are known agricultural pests as larvae (army cutworms), suggesting that seasonal dietary flexibility in big brown bats has economic benefits.

    Four species of ticks known to parasitize humans (Amblyomma americanum (lone star tick), Dermacentor variabilis (American dog tick), Amblyomma maculatum (Gulf Coast tick), and Ixodes scapularis (black-legged tick)) were collected at Joint Base Langley-Eustis, Fort Eustis, Virginia during 2009. These ticks were tested individually (adults and nymphs) and in pools of 15 (larvae) for pathogens of public health importance within the genera: Rickettsia, Borrelia, and Ehrlichia, by quantitative real-time polymerase chain reaction (qPCR) assays and, where appropriate, multilocus sequence typing (MLST). Of the 340 A americanum ticks tested, a minimum of 65 (19%), 4 (1%), 4 (1%), and one (<1%) were positive for Rickettsia amblyommii, B lonestari, E ewingii and E chaffeensis, respectively. One of 2 (50%) A maculatum ticks collected was found to be positive for R parkeri by MLST and qPCR analyses. All 33 D variabilis ticks were negative for evidence of rickettsial infections. Likewise, no pathogenic organisms were detected from the single Ixodes scapularis tick collected. Pathogenic rickettsiae and ehrlichiae are likely emerging and cause under-recognized diseases, which threaten people who live, work, train, or otherwise engage in outdoor activities at, or in the vicinity of, Fort Eustis, Virginia.

    Delabrouille, Frédéric

    2004-01-01

    La corrosion sous contrainte (CSC) est un mode de dégradation qui affecte de nombreux alliages au sein des réacteurs à eau sous pression, notamment les alliages base nickel tubes des générateurs de vapeur (GV). La fissuration qu'elle engendre intervient tant du côté primaire que secondaire, en particulier dans des zones où la composition du milieu est mal définie. La sensibilité à la CSC des alliages base nickel dépend de leur teneur en chrome, ce qui a conduit au remplacement de l'alliage 60...

  2. Dans le ventre du Léviathan. La science du droit constitutionnel sous le national-socialisme

    Directory of Open Access Journals (Sweden)

    Michael Stolleis

    2006-04-01

    Full Text Available Dans cet article Michael Stolleis s’intéresse au devenir de la science du droit constitutionnel sous le régime national-socialiste. L’intérêt de la question dépasse la simple curiosité historique, car elle concerne une discipline de la science juridique centrale à tout État démocratique. Partant des attaques contre le positivisme juridique qui émergent au cours de la République de Weimar, l’article s’ouvre sur une typologie des groupes qui constituent l’Union des professeurs de droit public. Stolleis montre l’affaiblissement progressif des « positivistes » à la faveur des groupes à l’idéologie plus autoritaire et antidémocratique. Cette première typologie des forces en présence permet ensuite d’analyser plus finement les différentes attitudes face à la mise en place du régime national-socialiste – allant de l’émigration (extérieure ou intérieure à la collaboration, en passant par le retrait vers des domaines de la pensée juridique moins directement exposés politiquement. S’intéressant au destin de la discipline plutôt qu’aux devenirs individuels, Stolleis constate l’effacement progressif du droit constitutionnel face à un pouvoir n’acceptant aucune contrainte, aucune restriction. Au point que le silence des représentants de cette discipline semble total après 1938. Enfin, l’article se conclut sur un appel à l’étude historique de la période, d’autant plus nécessaire que l’immédiat après-guerre fut marqué par l’occultation des faits et la volonté de laisser le passé être le passé.

    The aim of this work is the study of fluid transfers induced by two types of stresses (test of tightness and LOCA-type accident), inside a concrete wall integrating the inhomogeneities and singularities susceptible to be present inside the confinement building of a nuclear reactor. After the study of several types of concretes, based on the permeabilities and types of gas flows involved, the experimental phase has permitted to test at scale 1 (1.3 m thickness) and in test and accidental conditions, a concrete composition which fulfills a representativeness criterion. The modeling part has been carried out using the thermo-hydro-mechanical model of non-saturated porous media, recently embedded inside the Code-Aster of EDF. The synthesis of physical observations and of numerical simulations has permitted to better constrain the different roles of the porous structure, in particular about the transposition between a air flow and a air + steam flow.

    The effects of different cooking temperatures (65, 75, and 85 °C) and cooking levels (medium and well) on some quality properties, the formation of heterocyclic aromatic amines (HCAs), and the migration level of bisphenol-A (BPA) in trout fillets cooked by sous-vide were investigated. As a result, as expected, cooking caused a reduction in water content of the samples, whereas pH, TBARS, L*, and b* values increased. Cooking loss values ranged between 14.78 and 20.51%. Whereas IQ, MeIQ, 7,8-DiMeIQx, 4,8-DiMeIQx, PhIP, AαC and MeAαC could not be detected in the analyzed samples, varying levels of IQx (up to 0.16 ng/g) and MeIQx (up to 5.66 ng/g) were detected. It was determined that total HCA amounts ranged between 1.28 and 5.75 ng/g, and all or a big part of the total HCAs belonged to MeIQx. In addition, the migration level of BPA in sous-vide-cooked samples ranged between 4.93 and 27.11 ng/g. PMID:27029998

    effective diffusivity varying with contact force and on-going convergence. The results agree broadly with those of previous compaction creep experiments performed using wet halite powder. Discrepancies with other workers results for single-contact dissolution experiments can be explained in terms of differences in experimental configuration and competition between driving forces. La dissolution sous contrainte (IPS - Intergranular Pressure Solution représente un mécanisme de lithification, de compaction et de déformation à l'échelle géologique pour une large gamme de roches. Les études expérimentales d'IPS réalisées sur des agrégats de quartz n'ont pas été couronnées de succès en raison d'un taux faible d'IPS, et les expériences IPS réalisées en utilisant une halite saturée comme analogue de roche (Spiers et Schutjens, 1990 ; Hickman et Evans, 1991 ont laissé des incertitudes quant au détail des mécanismes IPS et à la structure/saturation au contact du grain dans ce matériau. La présente étude fait état de quatre expériences de dissolution de contact réalisées sous microscope optique afin d'étudier le mécanisme et la cinétique de l'IPS pour des contacts simples halite/halite et halite/verre, chargés en eau salée (température ambiante. Des forces normales de contact dans la gamme de 1,0 à 2,6 N ont été appliquées en présence d'eau salée saturée en NaCl, induisant des pressions de 0,8 à 7,4 MPa. Des pertes de masse et des convergences - fonction du temps - ont été observées pour tous les contacts. Dans tous les cas, le fait de charger le contact (ou d'augmenter la charge sur le contact a conduit à la formation immédiate d'une morphologie de contact rugueuse, composée d'un motif d'îles et de canaux, contrôlé par des caractéristiques cristallographiques, à l'échelle de quelques microns. Cette microstructure non équilibrée a évolué dans le temps vers une face de contact optiquement plate. Le processus de convergence

  17. Developmental assessment of the Fort St. Vrain version of the Composite HTGR Analysis Program (CHAP-2)

    International Nuclear Information System (INIS)

    The Composite HTGR Analysis Program (CHAP) consists of a model-independent systems analysis mainframe named LASAN and model-dependent linked code modules, each representing a component, subsystem, or phenomenon of an HTGR plant. The Fort St. Vrain (FSV) version (CHAP-2) includes 21 coded modules that model the neutron kinetics and thermal response of the core; the thermal-hydraulics of the reactor primary coolant system, secondary steam supply system, and balance-of-plant; the actions of the control system and plant protection system; the response of the reactor building; and the relative hazard resulting from fuel particle failure. FSV steady-state and transient plant data are being used to partially verify the component modeling and dynamic smulation techniques used to predict plant response to postulated accident sequences

  18. Fort St. Vrain graphite site mechanical separation concept selection. Final report

    Berry, S.M.

    1993-09-01

    One of the alternatives to the disposal of the Fort St. Vrain (FSV) reactor spent nuclear fuel involves the separation of the fuel rods composed of compacts from the graphite fuel block assembly. After the separation of these two components, the empty graphite fuel blocks would be disposed of as a low level waste (provided the appropriate requirements are met) and the fuel compacts would be treated as high level waste material. This report deals with the mechanical separation aspects concerning physical disassembly of the FSV graphite fuel element into the empty graphite fuel blocks and fuel compacts. This report recommends that a drilling technique is the preferred choice for accessing the, fuel channel holes and that each hole is drilled separately. This report does not cover any techniques or methods to separate the triso fuel particles from the graphite matrix of the fuel compacts.

  20. Nondestructive examination of 54 fuel and reflector elements from Fort St. Vrain core segment 2

    International Nuclear Information System (INIS)

    Fifty-four fuel and reflector elements irradiated in core segment 2 of the Fort St. Vrain high-temperature gas-cooled reactor (HTGR) were nondestructively examined. The time- and volume-averaged graphite irradiation temperatures for the elements ranged from approx. 3500 to 7500C. The element-averaged fast neutron fluences ranged from approx. 0.2 to 1.6 x 1025 n/m2 (E > 29 fJ)/sub HTGR/. The elements, except for two fuel elements in which single localizeed cracks developed during irradiation, were in excellent condition. No evidence was observed of significant graphite oxidation or mechanical interaction beween elements. The cracks in the two elements did not affect their performance or handling. These elements were, otherwise, in excellent condition. Nearly all elements shrank in both the axial and radial directions, but the dimensional changes were relatively small
