  1. Planning for regional centers

    International Nuclear Information System (INIS)

    In conclusion, the successful development and implementation of a multinational nuclear fuel cycle project will require that it be economically viable and satisfy the overlying interests and concerns of the participants. To assure success, it is absolutely essential that the initial planning, development of project criteria, and implementation be based on an authoritative understanding of the real needs of and benefits to all potential participants. The organizational structure for such a project must contain appropriate checks and balances that are sufficient to protect investors, owners, and consumers. Because of its special nature, these checks and balances must also provide for satisfying other important interests, such as an operating organization that addresses nonproliferation concerns and nuclear safeguards. The next logical step in the evolution of regional nuclear complexes is to determine whether such an approach is, indeed, economically viable, financially attractive, and operationally practical. Those who have succeeded in structuring nonnuclear, energy-related complexes currently operating throughout the world today should be looked to for developing the feasibility study of this concept in the nuclear field

  2. Northeast Regional Planetary Data Center

    2005-01-01

    In 1980, the Northeast Planetary Data Center (NEPDC) was established with Tim Mutch as its Director. The Center was originally located in the Sciences Library due to space limitations but moved to the Lincoln Field Building in 1983 where it could serve the Planetary Group and outside visitors more effectively. In 1984 Dr. Peter Schultz moved to Brown University and became its Director after serving in a similar capacity at the Lunar and Planetary Institute since 1976. Debbie Glavin has served as the Data Center Coordinator since 1982. Initially the NEPDC was build around Tim Mutch's research collection of Lunar Orbiter and Mariner 9 images with only partial sets of Apollo and Viking materials. Its collection was broadened and deepened as the Director (PHS) searched for materials to fill in gaps. Two important acquisitions included the transfer of a Viking collection from a previous PI in Tucson and the donation of surplused lunar materials (Apollo) from the USGS/Menlo Park prior to its building being torn down. Later additions included the pipeline of distributed materials such as the Viking photomosaic series and certain Magellan products. Not all materials sent to Brown, however, found their way to the Data Center, e.g., Voyager prints and negatives. In addition to the NEPDC, the planetary research collection is separately maintained in conjunction with past and ongoing mission activities. These materials (e.g., Viking, Magellan, Galileo, MGS mission products) are housed elsewhere and maintained independently from the NEPDC. They are unavailable to other researchers, educators, and general public. Consequently, the NEPDC represents the only generally accessible reference collection for use by researchers, students, faculty, educators, and general public in the Northeast corridor.

    2011-01-01

    The Galactic Center has long been a region of interest for high-energy and very-high-energy observations. Many potential sources of GeV/TeV gamma-ray emission have been suggested, e.g., the accretion of matter onto the black hole, cosmic rays from a nearby supernova remnant, or the annihilation of dark matter particles. The Galactic Center has been detected at MeV/GeV energies by EGRET and recently by Fermi/LAT. At GeV/TeV energies, the Galactic Center was detected by different ground-based Cherenkov telescopes such as CANGAROO, Whipple 10m, H.E.S.S., and MAGIC. We present the results from 15 hrs of VERITAS observations conducted at large zenith angles, resulting in a >10 standard deviation detection and confirmation of the high-energy spectrum observed by H.E.S.S. The combined Fermi/VERITAS results are compared to astrophysical models.

    The Southern Regional Center for Lightweight Innovative Design (SRCLID) has developed an experimentally validated cradle-to-grave modeling and simulation effort to optimize automotive components in order to decrease weight and cost, yet increase performance and safety in crash scenarios. In summary, the three major objectives of this project are accomplished: To develop experimentally validated cradle-to-grave modeling and simulation tools to optimize automotive and truck components for lightweighting materials (aluminum, steel, and Mg alloys and polymer-based composites) with consideration of uncertainty to decrease weight and cost, yet increase the performance and safety in impact scenarios; To develop multiscale computational models that quantify microstructure-property relations by evaluating various length scales, from the atomic through component levels, for each step of the manufacturing process for vehicles; and To develop an integrated K-12 educational program to educate students on lightweighting designs and impact scenarios. In this final report, we divided the content into two parts: the first part contains the development of building blocks for the project, including materials and process models, process-structure-property (PSP) relationship, and experimental validation capabilities; the second part presents the demonstration task for Mg front-end work associated with USAMP projects.

    The main objective of the Northwest Clean Energy Application Center (NW CEAC) is to promote and support implementation of clean energy technologies. These technologies include combined heat and power (CHP), district energy, waste heat recovery with a primary focus on waste heat to power, and other related clean energy systems such as stationary fuel cell CHP systems. The northwest states include AK, ID, MT, OR, and WA. The key aim/outcome of the Center is to promote and support implementation of clean energy projects. Implemented projects result in a number of benefits including increased energy efficiency, renewable energy development (when using opportunity fuels), reduced carbon emissions, improved facility economics helping to preserve jobs, and reduced criteria pollutants calculated on an output-based emissions basis. Specific objectives performed by the NW CEAC fall within the following five broad promotion and support categories: 1) Center management and planning including database support; 2) Education and Outreach including plan development, website, target market workshops, and education/outreach materials development 3) Identification and provision of screening assessments & feasibility studies as funded by the facility or occasionally further support of Potential High Impact Projects; 4) Project implementation assistance/trouble shooting; and 5) Development of a supportive clean energy policy and initiative/financing framework.

    Aims. Our aim is to confirm the interstellar detection of cyanic acid, HOCN, in the Galactic center clouds. It has previously been tentatively detected only in Sgr B2(OH). Methods. We used a complete line survey of the hot cores Sgr B2(N) and (M) in the 3 mm range, complemented by additional observations carried out with the IRAM 30 m telescope at selected frequencies in the 2 mm band and towards four additional positions in the Sgr B2 cloud complex in the 2 and 3 mm bands. The spectral survey was analysed in the local thermodynamical equilibrium approximation (LTE) by modeling the emission of all identified molecules simultaneously. This allowed us to distinguish weak features of HOCN from the rich line spectrum observed in Sgr B2(N) and (M). Lines of the more stable (by 1.1 eV) isomer isocyanic acid, HNCO, in these sources, as well as those of HOCN and HNCO towards the other positions, were analysed in the LTE approximation as well. Results. Four transitions of HOCN were detected in a quiescent molecular cl...

  9. Regional pollution potentials of megacities and other major population centers

    Full Text Available Megacities and other major population centers represent large, concentrated sources of anthropogenic pollutants to the atmosphere, with consequences for both local air quality and for regional and global atmospheric chemistry. The tradeoffs between the regional buildup of pollutants near their sources versus long-range export depend on meteorological characteristics which vary as a function of geographical location and season. Both horizontal and vertical transport contribute to pollutant export, and the overall degree of export is strongly governed by the lifetimes of pollutants. We provide a first quantification of these tradeoffs and the main factors influencing them in terms of "regional pollution potentials", metrics based on simulations of representative tracers using the 3-D global model MATCH (Model of Atmospheric Transport and Chemistry. The tracers have three different lifetimes (1, 10, and 100 days and are emitted from 36 continental large point sources. Several key features of the export characteristics emerge. For instance, long-range near-surface pollutant export is generally strongest in the middle and high latitudes, especially for source locations in Eurasia, for which 17–34% of a tracer with a 10-day lifetime is exported beyond 1000 km and still remains below 1 km altitude. On the other hand, pollutant export to the upper troposphere is greatest in the tropics, due to transport by deep convection, and for six source locations, more than 50% of the total mass of the 10-day lifetime tracer is found above 5 km altitude. Furthermore, not only are there order of magnitude interregional differences, such as between low and high latitudes, but also often substantial intraregional differences, which we discuss in light of the regional meteorological characteristics. We also contrast the roles of horizontal dilution and vertical mixing in reducing the pollution buildup in the regions including and surrounding the sources. For some

    Full Text Available INTRODUCTION: Female sex workers (FSWs are at high risk of HIV infection. Our objective was to determine the proportion of HIV prevalence in the general female adult population that is attributable to the occupational exposure of female sex work, due to unprotected sexual intercourse. METHODS: Population attributable fractions of HIV prevalence due to female sex work were estimated for 2011. A systematic search was conducted to retrieve required input data from available sources. Data gaps of HIV prevalence in FSWs for 2011 were filled using multilevel modeling and multivariate linear regression. The fraction of HIV attributable to female sex work was estimated as the excess HIV burden in FSWs deducting the HIV burden in FSWs due to injecting drug use. RESULTS: An estimated fifteen percent of HIV in the general female adult population is attributable to (unsafe female sex work. The region with the highest attributable fraction is Sub Saharan Africa, but the burden is also substantial for the Caribbean, Latin America and South and Southeast Asia. We estimate 106,000 deaths from HIV are a result of female sex work globally, 98,000 of which occur in Sub-Saharan Africa. If HIV prevalence in other population groups originating from sexual contact with FSWs had been considered, the overall attributable burden would probably be much larger. DISCUSSION: Female sex work is an important contributor to HIV transmission and the global HIV burden. Effective HIV prevention measures exist and have been successfully targeted at key populations in many settings. These must be scaled up. CONCLUSION: FSWs suffer from high HIV burden and are a crucial core population for HIV transmission. Surveillance, prevention and treatment of HIV in FSWs should benefit both this often neglected vulnerable group and the general population.

  15. Large resonance enhanced second order susceptibilities in alkali halide crystals due to FA color centers

    International Nuclear Information System (INIS)

    Model calculation of second order susceptibilities for FA color centers in wide band gap materials is reported. The second order optical nonlinearity in KCL:Li crystals due to FA color centers evaluated theoretically. The density matrix formalism is employed and the equation of motion is solved by second order perturbation to evaluate the nonlinear optical susceptibility for second harmonic generation as well as frequency mixing. It is found that the system shows large resonance-enhanced second order susceptibilities (≅10-16 mV-1) for color center concentration of ≅1023 m-3. A scheme of phase matching in terms of anomalous dispersion of the centers and coherent length are discussed (Author)

  16. Optimization of slender wings for center-of-pressure shift due to change in Mach number

    Science.gov (United States)

    Andersen, Carl M.

    1988-01-01

    It is observed that the center of pressure on a wing shifts as the Mach number is changed. Such shifts are in general undesirable and are sometimes compensated for by actively shifting the center of gravity of the aircraft or by using active stability controls. To avoid this complication, it is desirable to design the wings of a high speed aircraft so as to minimize the extent of the center-of-pressure shifts. This, together with a desire to minimize the center-of-pressure shifts in missile control surfaces, provides the motivation for this project. There are many design parameters which affect center-of-pressure shifts, but it is expected that the largest effects are due to the wing planform. Thus, for the sake of simplicity, this study is confined to an investigation of thin, flat, (i.e., no camber or twist), relatively slender, pointed wings flying at a small angle of attack. Once the dependence of the center of pressure on planform and Mach number is understood, we can expect to investigate the sensitivity of the center-of-pressure shifts to various other parameters.

  17. RF Regional Technical Centers for MPC and A Sustainability Operations

    International Nuclear Information System (INIS)

    The National Nuclear Security Administration (NNSA) programmatic vision to be a catalyst in Russia's assumption of responsibility for long-term system operation is exemplified in the sustainability cooperation with the RF Ministry of Defense (MOD). An identified goal for the MPC and A Program is to encourage the development of Russian Federation (RF) capabilities and commitments to operate and maintain safeguard improvements. The RF MOD Technical Support Center development fulfills the NNSA mission and MPC and A Program goal. The regional technical center concept involves a systematic approach to aid in the determination of the level of sustainability assistance required to transition operators, maintenance, training, and testing of MPC and A systems to the RF MOD. This paper describes the process used to create the RF MOD Technical support center. First are described the needs analyses conducted to determine the key system sustainability factors requiring support. These sustainability functions are then compiled to influence the form and ultimate physical design of the technical support center. Operational interfaces are described, in detail that show the benefit of the center to the individual sites. Finally, benefits relating to information accessibility and other economies of scale are described that highlight the central center concept's strengths

    By 2025, 60 to 80 percent of the world s population will live in urban environments. Additionally, the following facts published by the United Nations further illustrates how cities will evolve in the future. Urban areas in the developing world are growing very rapidly. The urban growth rate will continue to be particularly rapid in the urban areas of less developed regions, averaging 2.4 per cent per year during 2000-2030, consistent with a doubling time of 29 years. The urbanization process will continue worldwide. The concentration of population in cities is expected to continue so that, by 2030, 84 percent of the inhabitants of more developed countries will be urban dwellers. Urbanization impacts the whole hierarchy of human settlements. In 2000,24.8 per cent of the world population lived in urban settlements with fewer than 500,000 inhabitants and by 2015 that proportion will likely rise to 27.1 per cent.

  19. Argentina, regional training center on radiation protection for Latin America

    International Nuclear Information System (INIS)

    Argentina has an extensive background in education and training on Radiation Protection. Since the beginning of the nuclear activity in the country, prominence was given to the aspects related to radiation protection and training of the personnel involved in the use of ionizing radiation. These educative activities have been delivered for more than 50 years, having accumulated an important experience in the field. The Nuclear Regulatory Authority has the statutory obligation to address, among other matters, the control of the aspects of nuclear safety and radiation protection on the whole country, to protect the people of the harmful effects of ionizing radiation resulting from the nuclear activities. This includes the responsibility to develop and enforce the regulations, standards and other requirements, particularly, establishing the requests and promoting activities regarding education and training on radiation protection. Argentina, currently through the Nuclear Regulatory Authority, has performed postgraduate courses on radiation protection and nuclear safety at inter regional and regional level for 28 years without interruption. This important experience has been valued and exploited to form a Regional Center on Education and Training for Latin America and the Caribbean, sponsored by the International Atomic Energy Agency. The Regional Center that in fact has been running in Argentina, trained 404 foreign participants and 327 local participants since 1980, totalizing 731 graduates from our annual post graduate courses. Our commitment is that all the effort made in education and training on radiation protection and nuclear safety contributes to a better use of the benefits of nuclear development. Since 2001 the International Atomic Energy Agency raised the need to develop plans and establish agreements to ensure a long-term sustainability of the education and training programs, allowing a better use of the resources in this area. In order to achieve this goal

  5. A real-time audit of radiation therapy in a regional cancer center

    International Nuclear Information System (INIS)

    Purpose: To report the development, structure, and implementation of a real-time clinical radiotherapy audit of the practice of radiation oncology in a regional cancer center. Methods and Materials: Radiotherapy treatment plans were audited by a real-time peer-review process over an 8-year period (1989-1996). The overall goal of the audit was to establish a process for quality assurance (QA) of radiotherapy planning and prescription for individual patients. A parallel process was developed to audit the implementation of intervention-specific radiotherapy treatment policies. Results: A total of 3052 treatment plans were audited. Of these, 124 (4.1%) were not approved by the audit due to apparent errors in radiation planning. The majority of the nonapproved plans (79%) were modified prior to initiating treatment; the audit provided important clinical feedback about individual patient care in these instances. Most of the remaining nonapproved plans were deviations from normal practice due to patient-specific considerations. A further 110 (3.6% of all audited plans) were not approved by the audit due to deviations from radiotherapy treatment policy. A minority of these plans (22%) were modified prior to initiating treatment and the remainder provided important feedback for continuous quality improvement of treatment policies. Conclusion: A real-time audit of radiotherapy practice in a regional cancer center setting proved feasible and provided important direct and indirect patient benefits

    The rapid growth of the small wind turbine (SWT) market is attracting numerous entrants. Small wind turbine purchasers now have many options but often lack information (such as third-party certification) to select a quality turbine. Most SWTs do not have third-party certification due to the expense and difficulty of the certification process. Until recently, the only SWT certification bodies were in Europe. In North America, testing has been limited to a small number of U.S. Department of Energy (DOE) subsidized tests conducted at the National Wind Technology Center (NWTC) under the ongoing Independent Testing Project. Within the past few years, the DOE, National Renewable Energy Lab (NREL), and some states have worked with the North American SWT industry to create a SWT certification infrastructure. The goal is to increase the number of certified turbines and gain greater consumer confidence in SWT technology. The American Wind Energy Association (AWEA) released the AWEA Small Wind Turbine Performance and Safety Standard (AWEA Standard 9.1 - 2009) in December 2009. The Small Wind Certification Council (SWCC), a North American certification body, began accepting applications for certification to the AWEA standard in February 2010. To reduce certification testing costs, DOE/NREL is providing financial and technical assistance for an initial round of tests at four SWT test sites which were selected via a competitive solicitation. The four organizations selected are Windward Engineering (Utah), The Alternative Energy Institute at West Texas A&M (Texas), a consortium consisting of Kansas State University and Colby Community College (Kansas), and Intertek (New York). Each organization will test two small wind turbines as part of their respective subcontract with DOE/NREL. The testing results will be made publically available. The goal is to establish a lower-cost U.S. small wind testing capability that will lead to increased SWT certification.

    2012-06-01

    Photoluminescence (PL) spectra of single silicon vacancy (SiV) centers in diamond frequently feature very narrow room temperature PL lines in the near-infrared (NIR) spectral region, mostly between 820 nm and 840 nm, in addition to the well known zero-phonon line (ZPL) at approximately 738 nm [E. Neu , Phys. Rev. BPRBMDO1098-012110.1103/PhysRevB.84.205211 84, 205211 (2011)]. We here exemplarily prove for a single SiV center that this NIR PL is due to an additional purely electronic transition (ZPL). For the NIR line at 822.7 nm, we find a room temperature linewidth of 1.4 nm (2.6 meV). The line saturates at similar excitation power as the ZPL. The ZPL and NIR line exhibit identical polarization properties. Cross-correlation measurements between the ZPL and the NIR line reveal anticorrelated emission and prove that the lines originate from a single SiV center, furthermore indicating a fast switching between the transitions (0.7 ns). g(2) autocorrelation measurements exclude that the NIR line is a vibronic sideband or that it arises due to a transition from/to a metastable (shelving) state.

  8. Discovery of K-Shell Emission Lines of Neutral Atoms in the Galactic Center Region

    The K-shell emission line of neutral irons from the Galactic center (GC) region is one of the key for the structure and activity of the GC. The origin is still open question, but possibly due either to X-ray radiation or to electron bombarding to neutral atoms. To address this issue, we analyzed the Suzaku X-ray spectrum from the GC region of intense neutral iron line emission, and report on the discovery of Kalpha lines of neutral argon, calcium, chrome, and manganese atoms. The equivalent widths of these Kalpha lines indicate that the metal abundances in the GC region should be ~1.6 and ~4 of solar value, depending on the X-ray and the electron origins, respectively. On the other hand, the metal abundances in the hot plasma in the GC region are found to be ~1-2 solar. These results favor that the origin of the neutral Kalpha lines are due to X-ray irradiation.

  9. Measurement of HO{sub x}{center_dot} production rate due to radon decay in air

    1993-08-01

    Radon in indoor air may cause the exposure of the public to excessive radioactivity. Radiolysis of water vapor in indoor air due to radon decay could produce ({center_dot}OH and HO{sub 2} {center_dot}) that may convert atmospheric constituents to compounds of lower vapor pressure. These lower vapor pressure compounds might then nucleate to form new particles in the indoor atmosphere. Chemical amplification was used to determine HO{sub x}{center_dot} production rate in indoor air caused by radon decay. Average HO{sub x}{center_dot} production rate was found to be (4.31{plus_minus}0.07) {times} 10{sup 5} HO{sub x}{center_dot} per Rn decay per second (Bq) 3.4 to 55.0% at 22C. This work provided G{sub (HO{sub x}{center_dot})}-value, 7.86{plus_minus}0.13 No./100 eV in air by directly measuring [HO{sub x}{center_dot}] formed from the radiolysis procedure. This G value implies that HO{sub x}{center_dot} produced by radon decay in air might be formed by multiple processes and may be result of positive ion-molecule reactions, primary radiolysis, and radical reactions. There is no obvious relation between HO{sub x}{center_dot} production rate and relative humidity. A laser-induced fluorescence (LIF) system has been used for {center_dot}OH production rate measurement; it consists of an excimer laser, a dye laser, a frequency doubler, a gaseous fluorescence chamber, and other optical and electronic parts. This system needs to be improved to eliminate the interferences of light scattering and artificial {center_dot}OH produced from the photolysis of O{sub 3}/H{sub 2}O.

  10. Ultrasonic dispersion due to off-center rattling in NdOs4Sb12

    International Nuclear Information System (INIS)

    Ultrasonic investigation for the single crystals of ferromagnetic filled skutterudite compound NdOs4Sb12 was performed. A marked frequency dependence of the ultrasonic dispersion has been observed in a longitudinal elastic constant C11 at temperature centered around 45 K; however, no dispersion was measured in the transverse elastic constant C44. Such a clear mode difference in the ultrasonic dispersion, which has been found in PrOs4Sb12, strongly suggests that Nd ion in NdOs4Sb12 bears thermally activated off-center rattling effect

    Full Text Available Introduction: More and more patients have been undergoing electrophysiological study (EPS as the number of rhythmologists have increased. Due to the increased interest in the study, today EPS applications are made even in second step public hospitals or private hospitals. Our aim is to compare two electrophysiology labs, that are in different regions with social and economic development, in terms of patient demography, diagnosis, amount of diagnostic and curative interventions. Materials and Methods: In this study, two centers from two different regions of Turkey were selected; a training and research center (center 1 in the Western part and a public hospital (center 2 in the Eastern part of the country. Records of the patients who undergone EPS in these two centers were retrospectively analyzed. Independent parametric data were evaluated by T-test, and categorical data via Mann-Whitney U test. A p value below 0.05 was accepted for significance. Results: A total of 83 patients were retrospectively analyzed (42 from center 1, 41 from center 2. Patients’ baseline demographic data was similar except intellectual status. Nevertheless, both groups differed based on the number of patients with diagnosis of atrioventricular reciprocating tachycardia (p=0.047. There was a significant difference in procedure types. Center 1 performed significantly higher number of curative procedures (p=0.039 than center 2. Conclusions: Nowadays, EPS is spread from specialized centers to middle-sized hospitals. Since specialized centers have more access to the advanced devices such as electro-anatomic mapping rather than conventional equipment, they are evaluating more complex cases with a variety of different diagnosis. Constructing a referral system from peripheral hospitals to distinguished centers in electrophysiology field would eliminate unnecessary and/or repeated procedures and decrease the expenses.

  13. Calculating energy storage due to topological changes in emerging active region NOAA AR 11112

    Tarr, L A

    2012-01-01

    The Minimum Current Corona (MCC) model provides a way to estimate stored coronal energy using the number of field lines connecting regions of positive and negative photospheric flux. This information is quantified by the net flux connecting pairs of opposing regions in a connectivity matrix. Changes in the coronal magnetic field, due to processes such as magnetic reconnection, manifest themselves as changes in the connectivity matrix. However, the connectivity matrix will also change when flux sources emerge or submerge through the photosphere, as often happens in active regions. We have developed an algorithm to estimate the changes in flux due to emergence and submergence of magnetic flux sources. These estimated changes must be accounted for in order to quantify storage and release of magnetic energy in the corona. To perform this calculation over extended periods of time, we must additionally have a consistently labeled connectivity matrix over the entire observational time span. We have therefore develop...

    On 1989 May 22, the High Energy X-ray and Gamma-ray Observatory for Nuclear Emissions, a balloon-borne high-resolution germanium spectrometer with an 18-deg FOV, observed the Galactic Center (GC) from 25 to 2500 keV. The GC photon spectrum is obtained from the count spectrum by a model-independent method which accounts for the effects of passive material in the instrument and scattering in the atmosphere. Besides a positron annihilation line with a flux of (10.0 +/- 2.4) x 10 exp -4 photons/sq cm s and a full width at half-maximum (FWHM) of (2.9 + 1.0, -1.1) keV, the spectrum shows a peak centered at (163.7 +/- 3.4) keV with a flux of (1.55 +/- 0.47) x 10 exp -3 photons/sq cm s and a FWHM of (24.4 +/- 9.2) keV. The energy range 450-507 keV shows no positronium continuum associated with the annihilation line, with a 2-sigma upper limit of 0.90 on the positronium fraction. The 164 keV feature is interpreted as Compton backscatter of broadened and redshifted annihilation radiation, possibly from the source 1E 1740.7-2942.

  16. CALCULATING ENERGY STORAGE DUE TO TOPOLOGICAL CHANGES IN EMERGING ACTIVE REGION NOAA AR 11112

    International Nuclear Information System (INIS)

    The minimum current corona model provides a way to estimate stored coronal energy using the number of field lines connecting regions of positive and negative photospheric flux. This information is quantified by the net flux connecting pairs of opposing regions in a connectivity matrix. Changes in the coronal magnetic field, due to processes such as magnetic reconnection, manifest themselves as changes in the connectivity matrix. However, the connectivity matrix will also change when flux sources emerge or submerge through the photosphere, as often happens in active regions. We have developed an algorithm to estimate the changes in flux due to emergence and submergence of magnetic flux sources. These estimated changes must be accounted for in order to quantify storage and release of magnetic energy in the corona. To perform this calculation over extended periods of time, we must additionally have a consistently labeled connectivity matrix over the entire observational time span. We have therefore developed an automated tracking algorithm to generate a consistent connectivity matrix as the photospheric source regions evolve over time. We have applied this method to NOAA Active Region 11112, which underwent a GOES M2.9 class flare around 19:00 on 2010 October 16th, and calculated a lower bound on the free magnetic energy buildup of ∼8.25 × 1030 erg over 3 days.

    International Nuclear Information System (INIS)

    We performed investigations to evaluate the radiation exposure due to the private use of drinking water in the region of the German Fichtelgebirge (300 km North Munich near the Czech border), where the content of Radon in ground water is very high. Besides the drinking water pathway the different practices in the household were investigated such as taking showers, stay in a hairdressing salon, operating a washing machine. (author)

    We describe the results of a radio continuum survey of the central 4x1deg with the 100 m Green Bank Telescope (GBT) at wavelengths of 3.5, 6, 20, and 90 cm. The 3.5 and 6 cm surveys are the most sensitive and highest resolution single dish surveys made of the central degrees of our Galaxy. We present catalogs of compact and extended sources in the central four degrees of our Galaxy, including detailed spectral index studies of all sources. The analysis covers star-forming regions such as Sgr B and Sgr C where we find evidence of a mixture of thermal and nonthermal emission. The analysis quantifies the relative contribution of thermal and nonthermal processes to the radio continuum flux density toward the GC region. In the central 4x1deg of the GC, the thermal and nonthermal flux fractions for all compact and diffuse sources are 28%/72% at 3.5 cm and 19%/81% at 6 cm. The total flux densities from these sources are 783+-52 Jy and 1063+-93 Jy at 3.5 and 6 cm, respectively, excluding the contribution of Galactic ...

    1991-11-01

    The purpose of this report is to develop an engineering design package to protect the Federal Emergency Management Agency (FEMA) National Radio System (FNARS) facilities against the effects of high-altitude electromagnetic pulses (HEMPS). This report refers to the FEMA Federal Regional Center (FRC) in Bothell, Washington. It is highly probably that there will be a heavy dependence upon high-frequency (hf) radio communications for long-haul communications following a nuclear attack on the continental United States, should one occur. To maintain the viability of the FEMA hf radio network during such a situation, the FNARS facilities must take measures to protect against the effects of HEMP that are likely to be created in a nuclear confrontation. The equipment under stress has already been designed and built so that little opportunity exists for equipment design changes that could raise the threshold levels at which malfunctions occur. The solution must then be to reduce HEMP-induced stresses on the system by means of tailored retrofit hardening measures using commercial protection devices when available. If is the intent of this report to define the particular hardening measures that will minimize the susceptibility of the network components to HEMP effects. To the extent economically viable, protective actions have been recommended for implementation, along with necessary changes or additions, during the period of the FNARS upgrade program. This report addresses electromagnetic pulse (EMP) effects only, and disregards any condition in which radiation effects may be a factor. This report identifies the systems in the facility considered critical for emergency option. To identify the critical systems in the facility and the EMP coupling paths into these systems, an EMP survey of the facility was conducted. Results of the survey are presented along with recommendations for tailored retrofit hardening measures to be implemented to protect the facility from EMP.

  1. Calculation of piezomagnetic fields due to uniform regional stresses in the inhomogeneously magnetized crust

    International Nuclear Information System (INIS)

    Complete text of publication follows. A simple procedure for calculation of piezomagnetic fields due to uniform regional stresses in the heterogeneously magnetized crust is proposed. There is a prominent similarity between spatial distributions of anomalies in the geomagnetic total force values due to magnetization structures in the Earth's crust and those due to the piezomagnetic signals arisen from there. This similarity enables us to compute the piezomagnetic field due to uniform regional stress without determination of explicit structure of the magnetization intensities in the crust. The situation is quite similar to that of 'reduction to the pole', which is often use for interpretation of magnetic survey data. We give an explicit formula that gives the 2-D spectrum of the piezomagnetic field from that of local magnetic anomalies, and applied the formula to a synthesized data. Obtained values are compared with the exact solution of the piezomagnetic field in order to check the efficacy of the novel method, and it is verified that the calculation by using the formula gives values precise enough for practical use.

    1994-01-01

    We study the NGS (Non-dissipative Gravitational Singularity) model, which successfully describes the non-linear stage of evolution of perturbations (see [1], [2] and references therein). This model predicts DM density distribution $\\rho(r) \\sim r^{-\\alpha}$ with $\\alpha \\simeq 1.8$ which holds from very small distances $r_{\\rm min} \\simeq 0.01~{\\rm pc}$ up to very large distances $r_{\\rm max} \\simeq 5~{\\rm Mpc}$. Assuming the neutralino to be a CDM particle, we calculate the annihilation of neutralinos in the vicinity of the singularity (Galactic Center). If neutralinos are the dominant component of DM in our Galaxy, the produced energy is enough to provide the whole observed activity of the GC. Neutralinos of the most general composition and of mass in the range $20~{\\rm GeV} \\leq m_\\c \\leq 1~{\\rm TeV}$ are considered. We find the neutralino compositions which give the relic density needed for the Mixed Dark Matter (MDM) model and we evaluate for these compositions the high-energy ($E_{\\gamma} > 100 ~{\\rm Me...

    2011-01-01

    Full Text Available Background: The minimum hemoglobin cutoff for blood donation in India is 12.5 gm% for both male and female donors and the minimum donation interval is 3 months. Donation of one unit of blood results in decrease in hemoglobin by 1 gm% and loss of 200-250 mg of iron. Donor deferral due to anemia is one of the major reasons of temporary rejection of blood donors. In the absence of further workup or advise, it results in loss of valuable donor base. Aim and Objective: To provide baseline information regarding the prevalence and spectrum of anemia in prospective blood donors to help plan a future strategy for donor management. Materials and Methods: Hemoglobin testing of donors was performed using Hemocue and Copper sulfate specific gravity method. Ethylene diamine tetraacetic acid sample of all the donors who failed either or both the screening tests was tested on automated analyzer for evaluation of hemoglobin and red blood cell indices. Results: Of all the donors, 15.5% were deferred due to anemia. Prevalence of anemia in prospective blood donors was 1.8%. It was significantly higher in female donors compared with male donors (34.2% vs 1.2%. The most common type of anemia was normocytic normochromic.

    Across the United States, metropolitan areas face challenges related to transportation and land use. An emerging policy in many regions is to promote development around higher-density, mixed-use (smart-growth) centers that create locally accessible nodes; many of these nodes are also linked to transit stops. Some metropolitan planning organizations (MPOs) have developed regional plans and incentive programs to encourage local governments to develop these centers. Incentives include grants as ...

  5. Changes in underground water regimes in the Straz region due to uranium mining

    International Nuclear Information System (INIS)

    The genesis of how the underground water regime in the Straz block has been affected by uranium extraction activities is described. Two extraction methods began to be applied there in the late 1960s, viz. conventional mining and in situ leaching with dilute sulfuric acid. Either of the methods requires specific hydrogeological conditions: mining requires good drying of the deposit, whereas in situ leaching requires virtually unchanged hydrogeological conditions. Extensive development of the two methods continued in the 1970s. The application of two mutually affecting extraction methods on a relatively small area resulted in an intolerable environmental burden affecting particularly the underground water, especially due to the acid solutions leaking towards the center of draining. The main risks following from changes in the underground water regime in the Straz are described, and the principles of the system approach to the sanitation of this regime are outlined.

    2010-01-01

    Full Text Available This paper presents two methods for accurately computing the periodic regions' centers. One method fits for the general M-sets with integer index number, the other fits for the general M-sets with negative integer index number. Both methods improve the precision of computation by transforming the polynomial equations which determine the periodic regions' centers. We primarily discuss the general M-sets with negative integer index, and analyze the relationship between the number of periodic regions' centers on the principal symmetric axis and in the principal symmetric interior. We can get the centers' coordinates with at least 48 significant digits after the decimal point in both real and imaginary parts by applying the Newton's method to the transformed polynomial equation which determine the periodic regions' centers. In this paper, we list some centers' coordinates of general M-sets' k-periodic regions (k=3,4,5,6 for the index numbers α=−25,−24,…,−1 , all of which have highly numerical accuracy.

    2014-04-01

    Full Text Available As an extreme scenario of dynamical sea level changes, regional sea surface height (SSH changes that occur in the North Atlantic due to an abrupt weakening of the Atlantic Meridional Overturning Circulation (AMOC are simulated. Two versions of the same ocean-only model are used to study the effect of ocean model resolution on these SSH changes: a high-resolution (HR strongly eddying version and a low-resolution (LR version in which the effect of eddies are parameterized. The weakening of the AMOC is induced in both model versions by applying strong freshwater perturbations around Greenland. A rapid decrease of the AMOC in the HR version induces much shorter return times of several specific regional and coastal extremes in North Atlantic SSH than in the LR version. This effect is caused by a change in main eddy pathways associated with a change in separation latitude of the Gulf Stream.

    Full Text Available The purpose of the study is examining Istanbul to find out whether or not it has the ability to become an appropriate location to host regional treasury centers. Hence; Simkova’s 11 location criteria are compared across Istanbul additionally Hong Kong and Singapore, being already attractive locations in South East Asia for multinational corporations to set up their regional finance offices, to specify Istanbul’s weaker facilities even if it is not regarded as a rival for Hong Kong and Singapore. The study contributes to the understanding of Simkova’s location criteria assessment before establishing a regional treasury center in any location, as it is applied to some European countries and three Asian countries: Brunei, Hong Kong and Singapore, previously. Lastly, it is concluded that Istanbul is not as superior as Hong Kong and Singapore but it has reasonable conditions to become an attractive location for regional treasury centers.

    On August 2007 the National Institute for Space Research started a task force to develop and operate a space weather program, which is known by the acronyms Embrace that stands for the Portuguese statement "Estudo e Monitoramento BRAasileiro de Clima Espacial" Program (Brazilian Space Weather Study and Monitoring program). The mission of the Embrace/INPE program is to monitor the Solar-Terrestrial environment, the magnetosphere, the upper atmosphere and the ground induced currents to prevent effects on technological and economic activities. The Embrace/INPE system monitors the physical parameters of the Sun-Earth environment, such as Active Regions (AR) in the Sun and solar radiation by using radio telescope, Coronal Mass Ejection (CME) information by satellite and ground-based cosmic ray monitoring, geomagnetic activity by the magnetometer network, and ionospheric disturbance by ionospheric sounders and using data collected by four GPS receiver network, geomagnetic activity by a magnetometer network, and provides a forecasting for Total Electronic Content (TEC) - 24 hours ahead - using a version of the SUPIM model which assimilates the two latter data using nudging approach. Most of these physical parameters are daily published on the Brazilian space weather program web portal, related to the entire network sensors available. Regarding outreach, it has being published a daily bulletin in Portuguese and English with the status of the space weather environment on the Sun, the Interplanetary Medium and close to the Earth. Since December 2011, all these activities are carried out at the Embrace Headquarter, a building located at the INPE's main campus. Recently, a comprehensive data bank and an interface layer are under commissioning to allow an easy and direct access to all the space weather data collected by Embrace through the Embrace web Portal. The information being released encompasses data from: (a) the Embrace Digisonde Network (Embrace DigiNet) that monitors

    Full Text Available OBJECTIVE: Deferral of blood donors due to low hematocrit and iron depletion is commonly reported in blood banks worldwide. This study evaluated the risk factors for low hematocrit and iron depletion among prospective blood donors in a large Brazilian blood center.METHOD: A case-control study of 400 deferred donors due to low hematocrit and 456 eligible whole blood donors was conducted between 2009 and 2011. Participants were interviewed about selected risk factors for anemia, and additional laboratory tests, including serum ferritin, were performed. Bivariate and multivariate analyses were performed to assess the association between predictors and deferral due to low hematocrit in the studied population and iron depletion in women.RESULTS: Donors taking aspirins or iron supplementation, those who reported stomachache, black tarry stools or hematochezia, and women having more than one menstrual period/month were more likely to be deferred. Risk factors for iron depletion were repeat donation and being deferred at the hematocrit screening. Smoking and lack of menstruation were protective against iron depletion.CONCLUSION: This study found some unusual risk factors related to gastrointestinal losses that were associated with deferral of donors due to low hematocrit. Knowledge of the risk factors can help blood banks design algorithms to improve donor notification and referral.

    A group of four compact HII regions associated with the well-known 50 km/s molecular cloud is the closest site of on-going star formation to the dynamical center of the Galaxy, at a projected distance of ~6 pc. We present a study of ionized gas based on the [NeII] (12.8 micron) line, as well as multi-frequency radio continuum, HST Pa alpha and Spitzer IRAC observations of the most compact member of the HII group, Sgr A East HII D. The radio continuum image at 6cm shows that this source breaks up into two equally bright ionized features, D1 and D2. The SED of the D source is consistent with it being due to a 25\\pm3 solar mass, star with a luminosity of 8\\pm3x10^4 solar luminosity. The inferred mass, effective temperature of the UV source and the ionization rate are compatible with a young O9-B0 star. The ionized features D1 and D2 are considered to be ionized by UV radiation collimated by an accretion disk. We consider that the central massive star photoevaporates its circumstellar disk on a timescale of 3x10^...

  2. Economic feasibility study of regional centers for nuclear fuel reprocessing in the developing countries

    International Nuclear Information System (INIS)

    The fuel cycle costs for the following three different economic alternatives were studied: (1) Reprocessing in an industrialized country (such as the U.S.); (2) Reprocessing in the individual developing country; (3) Reprocessing in a regional center. The nuclear fuel cycle cost for the ''Throw-away'' fuel cycle was evaluated. Among the six regions which were considered in this study, region one (South America including Mexico) was selected for the economic analysis of the nuclear fuel cycle for the above three alternatives. For evaluation of the cases where the fuel is reprocessed in a regional center or in an individual developing country, a unit reprocessing cost equation was developed. An economic evaluation was developed to estimate the least expensive method for transporting radioactive nuclear material by either leased or purchased shipping casks. The necessary equations were also developed for estimating plutonium transportation and the safeguard costs. On the basis of nuclear material and services requirements and unit costs for each component, the levelized nuclear fuel cycle costs for each alternative were estimated. Finally, by a comparison of cost, among these three alternatives plus the ''Throw-away'' case,it was found that it is not at all economical to build individual reprocessing plants inside the developing countries in region one. However, it also was found that the economic advantage of a regional center with respect to the first alternative is less than a 4% difference between their total fuel cycle costs. It is concluded that there is no great economic advantage in any developing countries to seek to process their fuel in one of the advanced countries. Construction of regional reprocessing centers is an economically viable concept

    Context: It is well known that the kinetic temperatures, Tkin, of the molecular clouds in the Galactic center region are higher than in typical disk clouds. However, the Tkin of the molecular complexes found at higher latitudes towards the giant molecular loops in the central region of the Galaxy is so far unknown. The gas of these high latitude molecular clouds (hereafter referred to as halo clouds) is located in a region where the gas in the disk may interact with the gas in the halo in the Galactic center region. Aims: To derive Tkin in the molecular clouds at high latitude and understand the physical process responsible for the heating of the molecular gas both in the Central Molecular Zone (the concentration of molecular gas in the inner 500 pc) and in the giant molecular loops. Methods: We measured the metastable inversion transitions of NH3 from (1,1) to (6,6) toward six positions selected throughout the Galactic central disk and halo. We used rotational diagrams and large velocity gradient modeling to...

  4. Numerical Investigation of High Tide Level Due to A Super Typhoon in A Coastal Region

    2007-01-01

    A numerical model of the coupling between astronomical tide and storm surge based on Mike 21 is applied to the coastal regions of Zhejiang Province. The model is used to simulate high tide levels combined with storm surge during 5 typhoons, including two super typhoons, that landed in the Province. In the model, the atmospheric forcing fields are calculated with parametric wind and pressure models. The computational results, with average computed errors of 13 cm for the high astronomical tide levels and 20 cm for the high storm-tide levels, show that the model yields good simulations. Typhoon No. 5612, the most intense to land in China since 1949, is taken as the typical super typhoon for the design of 5 typhoon routes, each landing at a different location along the coast. The possible extreme storm-tide levels along the coast are calculated by the model under the conditions of the 5 designed typhoon routes when they coincide with the spring tide. Results are compared with the high storm-tide levels due to the increase of the central atmospheric pressure at the base of a typical super typhoon, the change of tidal type, and the behavior of a Saomai-type typhoon. The results have practical significance for forecasting and minimization of damage during super typhoons.

    Full Text Available OBJECTIVE - To analyze the trends in risk of death due to cardiovascular diseases in the northern, northeastern, southern, southeastern, and central western Brazilian geographic regions from 1979 to 1996. METHODS - Data on mortality due to cardiovascular, cardiac ischemic, and cerebrovascular diseases in 5 Brazilian geographic regions were obtained from the Ministry of Health. Population estimates for the time period from 1978 to 1996 in the 5 Brazilian geographic regions were calculated by interpolation with the Lagrange method, based on the census data from 1970, 1980, 1991, and the population count of 1996, for each age bracket and sex. Trends were analyzed with the multiple linear regression model. RESULTS - Cardiovascular diseases showed a declining trend in the southern, southeastern, and northern Brazilian geographic regions in all age brackets and for both sexes. In the northeastern and central western regions, an increasing trend in the risk of death due to cardiovascular diseases occurred, except for the age bracket from 30 to 39 years, which showed a slight reduction. This resulted from the trends of cardiac ischemic and cerebrovascular diseases. The analysis of the trend in the northeastern and northern regions was impaired by the great proportion of poorly defined causes of death. CONCLUSION - The risk of death due to cardiovascular, cerebrovascular, and cardiac ischemic diseases decreased in the southern and southeastern regions, which are the most developed regions in the country, and increased in the least developed regions, mainly in the central western region.

    We explore how regional medical diplomacy can increase funding for global mental health initiatives. Interventions for infectious diseases have dominated medical diplomacy by focusing on security concerns. The global mental health movement has adopted similar strategies, but unsuccessfully since mental illnesses do not cause international epidemics. Instead, realpolitik arguments may increase funding by prioritizing economic productivity and regional diplomacy based on cultural ties to advance mental health services and research at the community level. In South Asia, initiatives to train personnel and provide refugee services offer a foundation for regional centers of excellence. This model can be expanded elsewhere. PMID:23918068

    The wind industry and the U.S. Department of Energy (DOE) are addressing technical challenges to increasing wind energy's contribution to the national grid (such as reducing turbine costs and increasing energy production and reliability), and they recognize that public acceptance issues can be challenges for wind energy deployment. Wind project development decisions are best made using unbiased information about the benefits and impacts of wind energy. In 2014, DOE established six wind Regional Resource Centers (RRCs) to provide information about wind energy, focusing on regional qualities. This document summarizes the status and drivers for U.S. wind energy development on regional and state levels. It is intended to be a companion to DOE's 2014 Distributed Wind Market Report, 2014 Wind Technologies Market Report, and 2014 Offshore Wind Market and Economic Analysis that provide assessments of the national wind markets for each of these technologies.

    A group of four compact H II regions associated with the well-known 50 km/s molecular cloud is the closest site of on-going star formation to the dynamical center of the Galaxy, at a projected distance of approximately 6 pc. We present a study of ionized gas based on the [Ne II] (12.8 micron) line, as well as multi-frequency radio continuum, Hubble Space Telescope Pa alpha, and Spitzer Infrared Array Camera observations of the most compact member of the H II group, Sgr A East H II D. The radio continuum image at 6 cm shows that this source breaks up into two equally bright ionized features, D1 and D2. The spectral energy distribution of the D source is consistent with it being due to a 25 =/- 3 solar mass star with a luminosity of 8 +/- 3 x 10(exp 4) Solar luminosity . The inferred mass, effective temperature of the UV source, and the ionization rate are compatible with a young O9-B0 star. The ionized features D1 and D2 are considered to be ionized by UV radiation collimated by an accretion disk. We consider that the central massive star photoevaporates its circumstellar disk on a timescale of 3x (exp 4) years giving a mass flux approximately 3 x 10(exp -5) Solar Mass / year and producing the ionized material in D1 and D2 expanding in an inhomogeneous medium. The ionized gas kinematics, as traced by the [Ne II] emission, is difficult to interpret, but it could be explained by the interaction of a bipolar jet with surrounding gas along with what appears to be a conical wall of lower velocity gas. The other H II regions, Sgr A East A-C, have morphologies and kinematics that more closely resemble cometary flows seen in other compact H II regions, where gas moves along a paraboloidal surface formed by the interaction of a stellar wind with a molecular cloud.

  10. MASSIVE STAR FORMATION OF THE SGR A EAST H II REGIONS NEAR THE GALACTIC CENTER

    International Nuclear Information System (INIS)

    A group of four compact H II regions associated with the well-known 50 km s-1 molecular cloud is the closest site of on-going star formation to the dynamical center of the Galaxy, at a projected distance of ∼6 pc. We present a study of ionized gas based on the [Ne II] (12.8 μm) line, as well as multi-frequency radio continuum, Hubble Space Telescope Paα, and Spitzer Infrared Array Camera observations of the most compact member of the H II group, Sgr A East H II D. The radio continuum image at 6 cm shows that this source breaks up into two equally bright ionized features, D1 and D2. The spectral energy distribution of the D source is consistent with it being due to a 25 ± 3 Msun star with a luminosity of 8 ± 3 x 104 Lsun. The inferred mass, effective temperature of the UV source, and the ionization rate are compatible with a young O9-B0 star. The ionized features D1 and D2 are considered to be ionized by UV radiation collimated by an accretion disk. We consider that the central massive star photoevaporates its circumstellar disk on a timescale of 3 x 104 years giving a mass flux ∼3 x 10-5 Msun yr-1 and producing the ionized material in D1 and D2 expanding in an inhomogeneous medium. The ionized gas kinematics, as traced by the [Ne II] emission, is difficult to interpret, but it could be explained by the interaction of a bipolar jet with surrounding gas along with what appears to be a conical wall of lower velocity gas.

    2005-01-01

    We briefly review the prominent thermal and nonthermal sources near the Galactic center. These sources include the young stellar clusters, the Sgr B complex as well as the large-scale nonthermal filaments and lobes. Some of the recent radio images of this region based on VLA and Green Bank Telescope observations are also presented. We then argue that the origin of the large-scale features within the inner two degrees of the Galactic center is tied to a past starburst activity in the nucleus of the Galaxy.

  12. Astronomers Surprised to Find Elongated Radio-Emitting Region At Center of Milky Way

    Science.gov (United States)

    1998-12-01

    have found increasing evidence that it is a supermassive black hole. The team of astronomers used the VLBA to determine the structure of Sgr A* at five radio wavelengths (6.0, 3.6, 2.0, 1.35 cm, and 7 mm). At long radio wavelengths the radiation from Sgr A* is seriously blurred due to the scattering by the interstellar electrons between the Galactic center and the Earth. But, as one moves to shorter wavelengths, the scatter -- or distortion -- decreases exponentially, thereby creating increasingly clearer images. Indeed, at the shortest wavelength of 7 mm, the scattering effects are finally small enough to reveal the true size and shape of Sgr A*. For an object of 2.5 million solar masses, its Schwarzschild radius -- or outer edge of the "gravity well" from which not even light itself can escape from the black hole's pull -- would be only about 7.5 million kilometers. That distance translates into only a twentieth of the mean distance between the Earth and the Sun -- an extraordinarily small area. The astronomers are particularly intrigued that the radio-emitting area immediately surrounding the event horizon has an elongated shape. The VLBA, a series of 10 individual telescopes located at sites across North America, can create, in effect, an enormous single telescope with an aperture thousands of kilometers wide, thus providing the resolution necessary to probe the relatively small region at the core of our galaxy. "We needed to be able to resolve very fine detail in order to determine Sgr A*'s size and shape," said Paul Ho of the Harvard-Smithsonian Center for Astrophysics. "The only way we were able to find these exciting results was through the excellent data we received from the VLBA." The VLBA is an instrument of the National Radio Astronomy Observatory, a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.

    Full Text Available Postural control during rapid movements may be impaired due to musculoskeletal pain. The purpose of this study was to investigate the effect of experimental knee-related muscle pain on the center of pressure (CoP displacement in a reaction time task condition.Nine healthy males performed two reaction time tasks (dominant side shoulder flexion and bilateral heel lift before, during, and after experimental pain induced in the dominant side vastus medialis or the tibialis anterior muscles by hypertonic saline injections. The CoP displacement was extracted from the ipsilateral and contralateral side by two force plates and the net CoP displacement was calculated.Compared with non-painful sessions, tibialis anterior muscle pain during the peak and peak-to-peak displacement for the CoP during anticipatory postural adjustments (APAs of the shoulder task reduced the peak-to-peak displacement of the net CoP in the medial-lateral direction (P<0.05. Tibialis anterior and vastus medialis muscle pain during shoulder flexion task reduced the anterior-posterior peak-to-peak displacement in the ipsilateral side (P<0.05.The central nervous system in healthy individuals was sufficiently robust in maintaining the APA characteristics during pain, although the displacement of net and ipsilateral CoP in the medial-lateral and anterior-posterior directions during unilateral fast shoulder movement was altered.

    Full Text Available The region called Istanbul West Atasehir neighbourhood is planned to be the area where Istanbul Finance Center Project is settled. It is expected that the underlying project will strongly affect the real estate prices in the neigbouring areas. Therefore, it would be a valuable information for investors who are planning to invest in real estates relating to the Istanbul Finance Center Project. By the theory of Huff’s the attractiveness of a location is strongly related to the distance. In order to determine the expected future increases in real estate prices for the neighbouring locations, a number of regional experienced real estate agents was inteviewed. Moreover, the factors that are expected to influence the real estate prices are identified and ranked by their significancy levels.

    We retrospectively evaluated the effect of the Loma Prieta earthquake on calls to 2 designated regional poison control centers (San Francisco and Santa Clara) in the area. In the immediate 12 hours after the earthquake, there was an initial drop (31%) in call volume, related to telephone system overload and other technical problems. Calls from Bay Area counties outside of San Francisco and Santa Clara decreased more dramatically than those from within the host counties where the poison control centers are located. In the next 2 days, each poison control center then handled a 27% increase in call volume. Requests for information regarding safety of water supplies and other environmental concerns were significantly increased. The number of cases of actual poisoning exposure decreased, particularly poison and drug ingestions in children. Most calls directly related to the earthquake included spills and leaks of hazardous materials and questions about water and food safety. Regional poison control centers play an essential role in the emergency medical response to major disasters and are critically dependent on an operational telephone system. PMID:1595244

    Regional studies have shown that climate change will affect climatic suitability for Arabica coffee (Coffea arabica) within current regions of production. Increases in temperature and changes in precipitation patterns will decrease yield, reduce quality and increase pest and disease pressure. This is the first global study on the impact of climate change on suitability to grow Arabica coffee. We modeled the global distribution of Arabica coffee under changes in climatic suitability by 2050s as projected by 21 global circulation models. The results suggest decreased areas suitable for Arabica coffee in Mesoamerica at lower altitudes. In South America close to the equator higher elevations could benefit, but higher latitudes lose suitability. Coffee regions in Ethiopia and Kenya are projected to become more suitable but those in India and Vietnam to become less suitable. Globally, we predict decreases in climatic suitability at lower altitudes and high latitudes, which may shift production among the major regions that produce Arabica coffee. PMID:25875230

    This paper examines the ground subsidence caused by the uniform extraction of fluids from a disc-shaped region located within a poroelastic halfspace. Biot's theory of poroelasticity is used to examine the problem. The fluid extraction over the circular region at the interior of the poroelastic domain induces time-dependent axisymmetric surface settlements. The theoretical results are also used to examine the accuracy of a multi-physics computational scheme that can be used to examine more complex geological settings.

    The U.S. Department of Energy Pacific Region Clean Energy Application Center (PCEAC) was formed in 2009 by the U.S. Department of Energy (DOE) and the California Energy Commission to provide education, outreach, and technical support to promote clean energy -- combined heat and power (CHP), district energy, and waste energy recovery (WHP) -- development in the Pacific Region. The region includes California, Nevada, Hawaii, and the Pacific territories. The PCEAC was operated as one of nine regional clean energy application centers, originally established in 2003/2004 as Regional Application Centers for combined heat and power (CHP). Under the Energy Independence and Security Act of 2007, these centers received an expanded charter to also promote district energy and waste energy recovery, where economically and environmentally advantageous. The centers are working in a coordinated fashion to provide objective information on clean energy system technical and economic performance, direct technical assistance for clean energy projects and additional outreach activities to end users, policy, utility, and industry stakeholders. A key goal of the CEACs is to assist the U.S. in achieving the DOE goal to ramp up the implementation of CHP to account for 20% of U.S. generating capacity by 2030, which is estimated at a requirement for an additional 241 GW of installed clean technologies. Additional goals include meeting the Obama Administration goal of 40 GW of new CHP by 2020, key statewide goals such as renewable portfolio standards (RPS) in each state, California’s greenhouse gas emission reduction goals under AB32, and Governor Brown’s “Clean Energy Jobs Plan” goal of 6.5 GW of additional CHP over the next twenty years. The primary partners in the PCEAC are the Department of Civil and Environmental Engineering and the Energy and Resources Group (ERG) at UC Berkeley, the Advanced Power and Energy Program (APEP) at UC Irvine, and the Industrial Assessment Centers (IAC

    The Galactic center is an interesting region for high-energy (0.1-100 GeV) and very-high-energy (E > 100 GeV) gamma-ray observations. Potential sources of GeV/TeV gamma-ray emission have been suggested, e.g., the accretion of matter onto the supermassive black hole, cosmic rays from a nearby supernova remnant (e.g. SgrA East), particle acceleration in a plerion, or the annihilation of dark matter particles. The Galactic center has been detected by EGRET and by Fermi/LAT in the MeV/GeV energy band. At TeV energies, the Galactic center was detected with moderate significance by the CANGAROO and Whipple 10 m telescopes and with high significance by H.E.S.S., MAGIC, and VERITAS. We present the results from three years of VERITAS observations conducted at large zenith angles resulting in a detection of the Galactic center on the level of 18 standard deviations at energies above ~2.5TeV.

  15. Dose estimation due to 129I release by nuclear installations. Local and regional scales

    International Nuclear Information System (INIS)

    On a regional scale, doses related to 129I release in the environment were calculated by two methods: the specific activity method and the critical pathway or transfer chain method. The transfer chain method evaluates all the possible pathways of man environmental exposure and calculates 129I concentration in the various part of the food chain and the corresponding exposure. This method enables a more realistic dose estimation than the specific activity method. On a regional scale, the published estimations of 129I release impact are few and based on very different hypothesis, nevertheless the results obtained are relatively similar

Methods: This was a retrospective study of patients diagnosed with retinoblastoma in Hospital São João, between 1978 and 2012. Results: Fifty patients with retinoblastoma were evaluated in our institution between 1978 and 2012. Four patients were excluded due to loss of follow-up. Among the 46 retinoblastoma cases, 33 (71.7% were unilateral and 13 (28.3% bilateral, with a mean age at diagnosis of 22.19 months and 6.92 months, respectively (P<0.001. Leukocoria was the most common presenting sign (36.9%, followed by strabismus (19.6%, a combination of leukocoria and strabismus (8.7%, and buphthalmia (2.2%. Between 1978 and 1992, nine retinoblastoma cases were referred to our hospital, all of them unilateral, and, in each case, enucleation was performed, with or without salvage therapy. Between 1993 and 2012, 18 eyes with retinoblastoma were successfully managed with conservative treatment. Conclusion: Demographic results were generally coincident with previous reports. It is crucial to screen leukocoria in pediatric practice, even in asymptomatic children. The outcome of retinoblastoma treatment in our hospital is similar to other series in developed countries.

    Our Nation's lands, waters, and ecosystems and the living and cultural resources they contain face myriad challenges from invasive species, the effects of changing land and water use, habitat fragmentation and degradation, and other influences. These challenges are compounded by increasing influences from a changing climate—higher temperatures, increasing droughts, floods, and wildfires, and overall increasing variability in weather and climate. The Department of the Interior (DOI) has established eight regional Climate Science Centers (CSC) (fig. 1) that will provide scientific information and tools to natural and cultural resource managers as they plan for conserving these resources in a changing world. The U.S. Geological Survey (USGS) National Climate Change and Wildlife Science Center (NCCWSC) is managing the CSCs on behalf of the DOI.

    Full Text Available Introduction: PVI is an effective, guideline-based treatment for drug refractory symptomatic AF. Balloon cryoablation has been shown to be a safe and effective method for PVI. In the STOP-AF trial, data was produced from practitioners performing PVI with significant experience at high volume centers. This study evaluates the effectiveness and safety of treating symptomatic, drug refractory AF with PVI via cryoablation after implementation in a regional medical center. Method: This represents a retrospective analysis of outcomes after cryoablation treatment for AF in 71 patients over 354.7 +/- 164.4 days. Reported and recorded episodes of AF were categorized into a representative percent of AF “burden” for each 90 day period. Primary effectiveness and safety end points paralleled those of the STOP-AF trial. Results: Patients undergoing cryoablation had a 91% reduction of AF burden at 6 months following the procedure with an event-free survival rate of 45.5 % at a mean follow up of 12 months. The mean burden reduction was 3.21% per quarter. Anti-arrhythmic and anticoagulant medication use was reduced by 14.3% and 26.8% respectively. Significant complications included one report of pulmonary vein stenosis, one report of pseudoaneurysm and 5.5% of patients had transient pericarditis or pericardial effusion following the procedure. Conclusion: The results of this study were comparable to those of the high volume multi-center STOP-AF trial. PVI via cryoablation is a safe and effective alternative treatment of drug refractory symptomatic AF in the setting of a regional medical center.

    The Trimble CenterPoint RTX service was introduced in 2011. It provides real-time GNSS positioning with global coverage and fast convergence. A regional augmentation approach was introduced for the mid-west region in the US in 2011 too, which resulted in convergence times of as little as a one minute while providing centimeter accurate positioning results of 4 cm in horizontal (95%). In spring 2014 the BeiDou system was included in the Trimble CenterPoint RTX service. Today it supports GPS, GLONASS, QZSS and BeiDou signals. Earlier publications have shown the benefits of using Galileo, BeiDou and QZSS in the RTX positioning service. This presentation will introduce improvements achieved with regional augmentation systems using the Trimble RTX approach. Experiences made in the last years and the recent achievements are shown demonstrating the possibility of reliable initialization using carrier phase ambiguity resolution in a couple of minutes using a correction signal from a geostationary L-band satellite.

  20. Gamma rays and neutrinos from a cosmic ray source in the Galactic Center region

    2013-01-01

    The center of the our Galaxy is a region where very energetic phenomena take place. In particular powerful cosmic ray sources can be located in that region. The cosmic rays accelerated in these sources may interact with ambient protons and/or low energy photons producing gamma rays and neutrinos. The observation of these two types of secondary particles can be very useful for the identification of the cosmic ray sources and for the understanding of the physical processes occurring during acceleration. Motivated by the excess in the neutrino spectrum recently reported by the IceCube Collaboration, we study in detail the shape of the gamma ray and neutrino spectra originated from the interaction of cosmic ray protons with ambient protons for sources located in the Galactic Center region. We consider different models for proton acceleration and study the impact on the gamma ray and neutrino spectra. We also discuss the possibility to constrain and even identify a particular neutrino source by using the informati...

  1. Extensional fault uplift of regional Franciscan blueschists due to subduction shallowing during the Laramide orogeny

    Krueger, S.W.; Jones, D.L. (Univ. of California, Berkeley (USA))

    1989-12-01

    Regional structural and stratigraphic relations in the northern California Coast Ranges require an episode of extensional tectonic unroofing of coherent blueschist terranes of the Eastern belt of the Franciscan complex along a crustal-scale, low-angle, normal-fault system, here named the Cost Range detachment. This tectonic unroofing occurred during the latest Cretaceous and early Tertiary, contemporaneous with the compressional Laramide orogeny of the North American interior. Dynamic models of accretionary wedges predict that shallowing of subduction, as has been inferred during the Laramide orogeny, will impart extensional stresses in the wedge above the subducting plate. The authors therefore suggest a single casual event--gradual shallowing of subduction in the latest Cretaceous and early Tertiary--to link the extensional fault uplift of regional Franciscan blueschists to Laramide compression in the North American interior.

  3. Regional Hydro-Climatic Changes due to Three Decades of Amazonian Deforestation

    A gamut of studies exist which posit that small scale conversion of forests to urban, pasture or cropland can trigger an increase in regional cloudiness and rain. Several of these studies, pertaining to early stages of Amazonian deforestation, attribute this phenomenon to heightened thermal triggering resulting from small-scale (a few kilometers) patchy deforestation. But it is not clear if this phenomenon can be extrapolated to contemporary (tens of kilometers) or future scales of deforestation. Here, we have carried out the first long-time period study of the effects of changing scales of Amazonian deforestation on regional cloudiness and precipitation using satellite observations made by GOES and TRMM. We have analyzed observations made over the deforested areas in the Brazilian state of Rondonia. We find a shift in the regional hydroclimatic regime over the three decades of deforestation - from spatially uniform cloudiness to dominant cloudiness in the downwind half of the deforested domain. This result is not consistent with a thermal triggering mechanism because thermal triggering would only explain the uniform cloud cover observed during the early stages of deforestation. To further investigate the mechanism, we have also carried out numerical simulations. We found that surface roughness gradients caused by contemporary large scales of deforestation can explain this observed transition. This transition is climatologically important for this region because it affects the observed spatial distribution of precipitation, which has become dominant in the downwind half of the deforested domain in contemporary times. The new mechanism identified here should be accounted for in planning for future land-use change in the Amazon.

    An optical model accounting for the East Asian dust is proposed as a result of theory calculation and composition analysis of the aerosol samples collected in China desert during the international project, "Studies on the Origin and Transport of Aeolian Dust and its Effects on Climate (ADEC)". Study indicates that dust aerosols emitting from China deserts have smaller imaginary parts of refractive indices, therefore absorb less and scatter more solar radiation than the most dust optical models published so far. Furthermore, the forward fraction of scattering is less and the backscattering is stronger than those of the other models. The seasonal averaged radiative forcing in spring, 2001 over east Asia-north Pacific region is simulated employing the new dust optical model. The net forcing at the top of atmosphere (TOA) is estimated as -0.943 W·m-2 for regional and seasonal mean, with shortwave and longwave contributions of -1.700 and 0.759 W·m-2, respectively. The surface net forcing is calculated to be -5.445 W·m-2, and made up of shortwave component of -6.250 W·m-2 and longwave component of +0.759 W·m-2. The distributions of TOA and surface net forcing over this region are also analyzed in this study.

  5. Potential impacts on regional climate due to land degradation in the Guizhou Karst Plateau of China

    International Nuclear Information System (INIS)

    The possible regional climatic effects of land condition change in the Guizhou Karst Plateau (GKP), which has experienced serious Karst Rocky Desertification (KRD) in the past decades, were investigated in this study using the Weather Research and Forecasting (WRF) regional climate model. It was shown that when compared with validation datasets, the WRF showed a high ability to downscale NCEP-DOE Reanalysis-2, which provided the initial and lateral boundary conditions for WRF, especially for the precipitation simulation. After land degradation over the GKP, the net radiation and evaporation were reduced mainly within the desertification area, consistent with the reduction in rainfall and the increase in surface temperature there. The southwest monsoon flow from the Bay of Bengal was weakened over the adjacent area to the northeast, influencing the East Asian summer monsoon. Meanwhile, the weaker low-layer anti-cyclone and the stronger horizontal convergence enhanced vertical motion in the southeastern coastal areas. Furthermore, owing to the decreased surface heating in the degradation experiment, the lifting over the GKP and neighboring regions to the east was limited, which resulted in a reduced rainfall within the GKP and strengthened the ascending motion downstream over 114°–122° E. Such circulation differences favored an increase in moisture flux and clouds, thereby causing more precipitation in coastal areas of southeast China. (letter)

    Full Text Available Air pollution by fine particulate matter (PM2.5 and ozone (O3 has increased strongly with industrialization and urbanization. We estimate the premature mortality rates and the years of human life lost (YLL caused by anthropogenic PM2.5 and O3 in 2005 for epidemiological regions defined by the World Health Organization (WHO. This is based upon high-resolution global model calculations that resolve urban and industrial regions in greater detail compared to previous work. Results indicate that 69% of the global population is exposed to an annual mean anthropogenic PM2.5 concentration of >10 μg m−3 (WHO guideline and 33% to > 25 μg m−3 (EU directive. We applied an epidemiological health impact function and find that especially in large countries with extensive suburban and rural populations, air pollution-induced mortality rates have been underestimated given that previous studies largely focused on the urban environment. We calculate a global respiratory mortality of about 773 thousand/year (YLL ≈ 5.2 million/year, 186 thousand/year by lung cancer (YLL ≈ 1.7 million/year and 2.0 million/year by cardiovascular disease (YLL ≈ 14.3 million/year. The global mean per capita mortality caused by air pollution is about 0.1% yr−1. The highest premature mortality rates are found in the Southeast Asia and Western Pacific regions (about 25% and 46% of the global rate, respectively where more than a dozen of the most highly polluted megacities are located.

    Soil erosion is the most important reason of sedimentation load of water reservoirs in the world. In Pakistan, Mangla dam is one of the most important water reservoirs used for the production of electricity and for the supply of water for irrigation purposes. However, the capacity of Mangla dam reservoir has reduced by more than 20% since its construction. This study highlights the impact of rainfall on soil erosion and consequently on sedimentation deposition in Mangla dam reservoir. Sedimentation, annual rainfall, and normal rainfall data of 39 years were used in this study. Shuttle Radar Topographic Mission data were used to calculate the total drainage area of the Mangla watershed region. The sedimentation data of Mangla reservoir from 1967 to 2005 were retrieved from Water and Power Development Authority in Pakistan. The meteorological observatories in the Mangla watershed region are identified. Annual rainfall data from 1967 to 2005 for the meteorological observatories in the Mangla watershed regions were retrieved from Pakistan Meteorological Department (PMD). In addition, normal rainfall data for the years 1949 to 1978 and for the years 1979 to 2008 were also retrieved from PMD. The impact of annual rainfall is observed on sedimentation load in Mangla dam. The correlation coefficient between annual rainfall and sedimentation load is 0.94. This study shows that with an increase in rainfall, the soil erosion of the area increases which subsequently is responsible for the increase in the rate of sedimentation load in Mangla dam. This study further demonstrates that better soil management can reduce the sedimentation load in the Mangla reservoir. PMID:21225339

    2012-01-01

    The galactic center (GC) has long been a region of interest for high-energy and very-high-energy observations. Many potential sources of GeV/TeV gamma-ray emission are located in the GC region, e.g. the accretion of matter onto the central black hole, cosmic rays from a nearby shell-type super nova remnant, or the annihilation of dark matter. The GC has been detected at MeV/GeV energies by EGRET and recently by Fermi/LAT. At TeV energies, the GC was detected at the level of 4 standard deviations with the Whipple 10m telescope and with one order of magnitude better sensitivity by H.E.S.S. and MAGIC. We present the results from 3 years of VERITAS GC observations conducted at large zenith angles. The results are compared to astrophysical models.

    The electron velocity distribution function and the incoherent scatter spectra during ionospheric heating in low ionosphere region are presented with consideration of the elastic collision between electrons and neural particles and the excitation of rotation energy level. The effects of pump frequency and electric fields on the spectra are discussed. With the increase of electric field, the non-Maxwellian feature is enhanced, and with the increase of heating frequency, the non-Maxwellian feature is weakened. The non-Maxwellian factor will bring a large error in ionosphere parameters, which must be considered in the inversion.

    Ultrasonic investigation for the single crystals of ferromagnetic filled skutterudite compound NdOs{sub 4}Sb{sub 12} was performed. A marked frequency dependence of the ultrasonic dispersion has been observed in a longitudinal elastic constant C{sub 11} at temperature centered around 45 K; however, no dispersion was measured in the transverse elastic constant C{sub 44}. Such a clear mode difference in the ultrasonic dispersion, which has been found in PrOs{sub 4}Sb{sub 12}, strongly suggests that Nd ion in NdOs{sub 4}Sb{sub 12} bears thermally activated off-center rattling effect.

    The purpose of this study was to evaluate the stability of measurement for apparent diffusion coefficient (ADC) values in normal brain, to clarify the effect of aging on ADC values, to compare ADC values between men and women, and to compare ADC values between right and left sides of the brain. To evaluate the stability of measurements, five normal volunteers (four men and one woman) were examined five times on different days. Then, 294 subjects with normal MR imaging (147 men and 147 women; age range 20-89 years) were measured. The ADC measurement in normal volunteers was stable. The ADC values stayed within the 5% deviation of average values in all volunteers (mean{+-}standard deviation 2.3{+-}1.2%). The ADC values gradually increased by aging in all regions. In thalamus, no significant difference was seen between right and left in the subjects under 60 years; however, right side showed higher values in the subjects over 60 years (p<0.01). In the subjects under 60 years, women showed higher values in right frontal, bilateral thalamus, and temporal (p<0.01); however, in the subjects over 60 years, no region showed difference between men and women. The knowledge obtained in this study may be helpful to understand the developmental and aging mechanisms of normal brain and may be useful for the future quantitative study as a reference. (orig.)

    Ionizing radiation is a safe and effective method for eliminating bacterial pathogens from food products and disinfestation of fruits and vegetables. Since 1980 research has been conducted at USDA's Eastern Regional Research Center pertaining to the elimination of food-borne pathogens from meat, poultry, fruit and vegetable products. Recent work has focused on elimination of pathogens such as Escherichia coli O157:H7, Salmonella spp., and Listeria monocytogenes from ready-to-eat (RTE) food products including hot dogs, bologna, lettuce, cilantro, sprouts and seeds, and frozen vegetables. The ionizing radiation dose required to eliminate those pathogens from RTE foods has been found to be commodity, formulation and temperature dependent. The need to eliminate bacterial pathogens from RTE food products must always be balanced with the maintenance of product quality. In addition to determining the effective ionizing radiation doses required for pathogen elimination the effects of irradiation on product chemistry, nutritional value and organoleptic quality have also been determined. A review of the studies conducted at USDA's Eastern Regional Research Center in 2002 and 2003 is presented in this article.

  20. Investigating the Uniformity of the Excess Gamma rays towards the Galactic Center Region

    2016-01-01

    We perform a composite likelihood analysis of subdivided regions within the central $26^\\circ\\times20^\\circ$ of the Milky Way, with the aim of characterizing the spectrum of the gamma-ray galactic center excess in regions of varying galactocentric distance. Outside of the innermost few degrees, we find that the radial profile of the excess is background-model dependent and poorly constrained. The spectrum of the excess emission is observed to extend upwards of 10 GeV outside $\\sim5^\\circ$ in radius, but cuts off steeply between 10--20 GeV only in the innermost few degrees. If interpreted as a real feature of the excess, this radial variation in the spectrum has important implications for both astrophysical and dark matter interpretations of the galactic center excess. Single-component dark matter annihilation models face challenges in reproducing this variation; on the other hand, a population of unresolved millisecond pulsars contributing both prompt and secondary inverse Compton emission may be able to expl...

  1. DNS of heat transfer increase in a cylinder stagnation region due to wake-induced turbulence

    International Nuclear Information System (INIS)

    Heat transfer in the stagnation point area of a heated cylinder is investigated using Direct Numerical Simulation (DNS). The heated cylinder is subjected to the turbulent wake of a smaller cylinder placed upstream. Two Reynolds numbers based on the diameter of the heated cylinder of 13,200 and 48,000 are chosen. In accordance with correlations in the literature, an increase in heat transfer compared to fully laminar flow is found for all angles along the front circumferential area of the heated cylinder. However, due to the presence of the wake, the maximum increase is shifted away from the centerline. The characteristic turbulence level and Nusselt number in the present study are an order of magnitude higher than those reported in previous simulations. The DNS results obtained, are in good agreement with an existing experimental correlation. Finally, relevant flow structures and instantaneous temperature fields are visualized.

  2. Regional Collaborations to Combat Climate Change: The Climate Science Centers as Strategies for Climate Adaptation

    2014-12-01

    The Department of Interior Northeast Climate Science Center (NE CSC) is part of a federal network of eight Climate Science Centers created to provide scientific information, tools, and techniques that managers and other parties interested in land, water, wildlife and cultural resources can use to anticipate, monitor, and adapt to climate change. The consortium approach taken by the CSCs allows the academic side of the Centers to gather expertise across departments, disciplines, and even institutions. This interdisciplinary approach is needed for successfully meeting regional needs for climate impact assessment, adaptive management, education, and stakeholder outreach. Partnership with the federal government facilitates interactions with the key on-the-ground stakeholders who are able to operationalize the results and conclusions of that research, monitor the progress of management actions, and provide feedback to refine future methodology and decisions as new information on climate impacts is discovered. For example, NE CSC researchers are analyzing the effect of climate change on the timing and volume of seasonal and annual streamflows and the concomitant effects on ecological and cultural resources; developing techniques to monitor tree range dynamics as affected by natural disturbances which can enable adaptation of projected climate impacts; studying the effects of changes in the frequency and magnitude of drought and stream temperature on brook trout habitats, spatial distribution and population persistence; and conducting assessments of northeastern regional climate projections and high-resolution downscaling. Project methods are being developed in collaboration with stakeholders and results are being shared broadly with federal, state, and other partners to implement and refine effective and adaptive management actions.

  3. A Two Dimensional Infinite Element Model to Study Temperature Distribution in Human Dermal Regions due to Tumors

    2005-01-01

    Full Text Available In this study, a two dimensional infinite element model has been developed to study thermal effect in human dermal regions due to tumors. This model incorporates the effect of blood mass flow rate, metabolic heat generation and thermal conductivity of the tissues.The dermal region is divided into three natural layers, namely, epidermis, dermis and subdermal tissues. A uniformly perfused tumor is assumed to be present in the dermis. The domain is assumed to be finite along the depth and infinite along the breadth. The whole dermis region involving tumor is modelled with the help of triangular finite elements to incorporate the geometry of the region. These elements are surrounded by infinite domain elements along the breadth. Appropriate boundary conditions has been incorporated. A computer program has been developed to obtain the numerical results.

  4. Coma Morphology Due to an Extended Active Region and Implications for the Spin State of Comet Hale-Bopp

    Samarasinha, Nalin H.

    2000-01-01

    We show that the circular character of continuum structures observed in the coma of comet Hale-Bopp around the perihelion passage is most likely due to a dust jet from a large extended active region on the surface. Coma morphology due to a wide jet is different from that due to a narrow jet. The latter shows foreshortening effects due to observing geometry, wider jet produces more circular features. This circularization effect provides a self-consistent explanation for the evolution of near-perihelion coma morphology. No changes in the direction of the rotational angular momentum vector are required during this period in contrast to the models of Schleicher et al. This circularization effect also enables us to produce near-circular coma features in the S-E quadrant during 1997 late February and therefore questions the basic premise on which Sekanina bases his morphological arguments for a gravitationally bound satellite nucleus.

  6. Hell and High Water: Diminished Septic System Performance in Coastal Regions Due to Climate Change.

    Science.gov (United States)

    Cooper, Jennifer A; Loomis, George W; Amador, Jose A

    2016-01-01

    Climate change may affect the ability of soil-based onsite wastewater treatment systems (OWTS) to treat wastewater in coastal regions of the Northeastern United States. Higher temperatures and water tables can affect treatment by reducing the volume of unsaturated soil and oxygen available for treatment, which may result in greater transport of pathogens, nutrients, and biochemical oxygen demand (BOD5) to groundwater, jeopardizing public and aquatic ecosystem health. The soil treatment area (STA) of an OWTS removes contaminants as wastewater percolates through the soil. Conventional STAs receive wastewater from the septic tank, with infiltration occurring deeper in the soil profile. In contrast, shallow narrow STAs receive pre-treated wastewater that infiltrates higher in the soil profile, which may make them more resilient to climate change. We used intact soil mesocosms to quantify the water quality functions of a conventional and two types of shallow narrow STAs under present climate (PC; 20°C) and climate change (CC; 25°C, 30 cm elevation in water table). Significantly greater removal of BOD5 was observed under CC for all STA types. Phosphorus removal decreased significantly from 75% (PC) to 66% (CC) in the conventional STA, and from 100% to 71-72% in shallow narrow STAs. No fecal coliform bacteria (FCB) were released under PC, whereas up to 17 and 20 CFU 100 mL-1 were released in conventional and shallow narrow STAs, respectively, under CC. Total N removal increased from 14% (PC) to 19% (CC) in the conventional STA, but decreased in shallow narrow STAs, from 6-7% to less than 3.0%. Differences in removal of FCB and total N were not significant. Leaching of N in excess of inputs was also observed in shallow narrow STAs under CC. Our results indicate that climate change can affect contaminant removal from wastewater, with effects dependent on the contaminant and STA type. PMID:27583363

  7. Simulation of hydrodynamic effects of salt rejection due to permafrost. Hydrogeological numerical model of density-driven mixing, at a regional scale, due to a high salinity pulse

    International Nuclear Information System (INIS)

    The main objective of this study is to support the safety assessment of the investigated candidate sites concerning hydrogeological and hydrogeochemical issues related to permafrost. However, a more specific objective of the study is to improve the assessment of processes in relation to permafrost scenarios. The model is based on a mathematical model that includes Darcy velocities, mass conservation, matrix diffusion, and salinity distribution. Gravitational effects are thus fully accounted for. A regional groundwater flow model (POM v1.1, Simpevarp) was used as basis for the simulations. The main results of the model include salinity distributions in time. The general conclusion is that density-driven mixing processes are contained within more permeable deformation zones and that these processes are fast as compared with preliminary permafrost growth rates. The results of the simulation suggest that a repository volume in the rock mass in-between the deterministic deformation zones, approximately 150 m below the permafrost will not experience a high salinity situation due to the salt rejection process

    International Nuclear Information System (INIS)

    Geological survey performed in the coastal region of the Northeast of Brazil showed presence of uranium phosphate deposits in a land strip corresponding to the Pernambuco-Paraiba sedimentary basin. The local population uses the water that crosses phosphate area, with higher than normal concentration of uranium and its progeny. this work is aimed to determine the cancer risk, based on the rate of ingestion the 226 Ra due to water consumption. The results of the analyses showed increments of 7% for head sarcoma and 3% for osteosarcomas occurrences due to 226 Ra ingestion for the local population. (author)

  11. Forecasting database for the tsunami warning regional center for the western Mediterranean Sea

    Science.gov (United States)

    Gailler, A.; Hebert, H.; Loevenbruck, A.; Hernandez, B.

    2010-12-01

    Improvements in the availability of sea-level observations and advances in numerical modeling techniques are increasing the potential for tsunami warnings to be based on numerical model forecasts. Numerical tsunami propagation and inundation models are well developed, but they present a challenge to run in real-time, partly due to computational limitations and also to a lack of detailed knowledge on the earthquake rupture parameters. Through the establishment of the tsunami warning regional center for NE Atlantic and western Mediterranean Sea, the CEA is especially in charge of providing rapidly a map with uncertainties showing zones in the main axis of energy at the Mediterranean scale. The strategy is based initially on a pre-computed tsunami scenarios database, as source parameters available a short time after an earthquake occurs are preliminary and may be somewhat inaccurate. Existing numerical models are good enough to provide a useful guidance for warning structures to be quickly disseminated. When an event will occur, an appropriate variety of offshore tsunami propagation scenarios by combining pre-computed propagation solutions (single or multi sources) may be recalled through an automatic interface. This approach would provide quick estimates of tsunami offshore propagation, and aid hazard assessment and evacuation decision-making. As numerical model accuracy is inherently limited by errors in bathymetry and topography, and as inundation maps calculation is more complex and expensive in term of computational time, only tsunami offshore propagation modeling will be included in the forecasting database using a single sparse bathymetric computation grid for the numerical modeling. Because of too much variability in the mechanism of tsunamigenic earthquakes, all possible magnitudes cannot be represented in the scenarios database. In principle, an infinite number of tsunami propagation scenarios can be constructed by linear combinations of a finite number of

    2016-06-01

    Abstract: We present 19.7, 25.2, 31.5, and 37.1 μm maps of the Thermal Arched Filament region in the Galactic Center taken with the Faint Object Infrared Camera for the SOFIA Telescope (FORCAST) with an angular resolution of 3.2-3.8". We calculate the integrated infrared luminosity of the Arched Filaments and show that they are consistent with being heated by the nearby Arches cluster. Additionally, using our observations, we infer dust temperatures (75 – 90 K) across the Arched Filaments which are remarkably consistent over large spatial scales (∼ 25 pc). We discuss the possible geometric effects needed to recreate this temperature structure. Additionally, we compare the observed morphology of the Arches in the FORCAST maps with the Paschen-α emission in the region to study what fraction of the infrared emission may be coming from dust in the HII region versus the PDR beneath it. Finally, we use Spitzer/IRAC 8 μm data to look for spatial variations in PAH abundance in the rich UV environment of the young (~2-4 Myr) and massive Arches cluster.

    2010-01-01

    Diffuse X-rays from the Galactic center (GC) region were found to exhibit many K-shell lines from iron and nickel atoms in the 6--9 keV band. The strong emission lines seen in the spectrum are neutral iron K$\\alpha$ at 6.4~keV, He-like iron K$\\alpha$ at 6.7~keV, H-like iron Ly$\\alpha$ at 6.9~keV, and He-like iron K$\\beta$ at 7.8~keV. Among them, the 6.4~keV emission line is a probe of non-thermal phenomena. We have detected strong 6.4~keV emission in several giant molecular clouds, some of which were newly discovered by Suzaku. All the spectra exhibit large equivalent widths of 1-2~keV and absorption columns of $2-10\\times 10^{23}\\{\\rm H\\ cm}^{-2}$. We found time variability of diffuse 6.4~keV emission in the Sgr B2 region comparing the maps and spectra obtained from 1994 to 2005 with ASCA, Chandra, XMM-Newton and Suzaku. We also report discovery of K$\\alpha$ lines of neutral argon, calcium, chrome, and manganese atoms in the Sgr~A region. We show that the equivalent width of the 6.4~keV emission line detecte...

  15. A method to determine the mammographic regions that show early changes due to the development of breast cancer

    International Nuclear Information System (INIS)

    It is well understood nowadays that changes in the mammographic parenchymal pattern are an indicator of a risk of breast cancer and we have developed a statistical method that estimates the mammogram regions where the parenchymal changes, due to breast cancer, occur. This region of interest is computed from a score map by utilising the anatomical breast coordinate system developed in our previous work. The method also makes an automatic scale selection to avoid overfitting while the region estimates are computed by a nested cross-validation scheme. In this way, it is possible to recover those mammogram regions that show a significant difference in classification scores between the cancer and the control group. Our experiments suggested that the most significant mammogram region is the region behind the nipple and that can be justified by previous findings from other research groups. This result was conducted on the basis of the cross-validation experiments on independent training, validation and testing sets from the case-control study of 490 women, of which 245 women were diagnosed with breast cancer within a period of 2–4 years after the baseline mammograms. We additionally generalised the estimated region to another, mini-MIAS study and showed that the transferred region estimate gives at least a similar classification result when compared to the case where the whole breast region is used. In all, by following our method, one most likely improves both preclinical and follow-up breast cancer screening, but a larger study population will be required to test this hypothesis. (paper)

  16. WMO SDS-WAS NAMEE Regional Center: Towards continuous evaluation of dust models in Northern Africa

    One of the most important activities of the Regional Center for Northern Africa, Middle East and Europe of the World Meteorological Organization's Sand and Dust Storm Warning Advisory and Assessment System (WMO SDS-WAS, http://sds-was.aemet.es) is the dust model intercomparison and forecast evaluation, which is deemed an indispensable service to the users and an invaluable tool to assess model skills. Currently, the Regional Center collects daily dust forecasts from models run by nine partners (BSC, ECMWF, NASA, NCEP, SEEVCCC, EMA, CNR-ISAC, NOA and UK Met Office). A multi-model ensemble has also been set up in an effort to provide added-value products to the users. The first problem to address the dust model evaluation is the scarcity of suitable routine observations near the Sahara, the world's largest source of mineral dust. The present contribution presents preliminary results of dust model evaluation using new observational datasets. The current routine evaluation of dust predictions is focused on total-column dust optical depth (DOD) and uses remote-sensing retrievals from sun-photometric (AERONET) and satellite (MODIS) measurements. However, most users of dust forecasts are interested in the concentration near the surface (in the air we breathe) rather than in the total column content. Therefore, evaluation of the predicted surface concentration is also necessary. In this context, the initiative of the African Monsoon Interdisciplinary Analysis (AMMA) International Program to establish permanent measuring stations in the Sahel is extremely important. Tapered Element Oscillating Microbalance (TEOM) monitors continuously record PM10 in M'Bour (Senegal); Cinzana (Mali) and Banizoumbou (Niger). This surface model evaluation is complemented with the PM10 observation from the Air Quality Control and Monitoring Network (AQCMN) of the Canary Islands (Spain). The region, located in the sub-tropical Eastern Atlantic (roughly 100 km west of the Moroccan coast), is

    An X-ray survey of the Galactic center region with a radius of ~20◦ has been performed using the data obtained with the JEM-X telescope onboard the INTEGRAL observatory over ~10 years of observations (2003-2013). The exposure at the field center directly toward the Galactic center has reached 4.8 Ms. We have constructed sky maps in the 5-10 and 10-25 keV energy bands and compiled a catalog of detected sources. Together with 83 sources revealed on the integral sky maps, it includes 22 transients that are absent on them but are confidently detected during outbursts with a duration of several days. One of the persistent sources, IGR J17452-2909, has never been observed previously. In contrast to the catalog of sources detected in the harder energy band by the IBIS/ISGRI telescope onboard the INTEGRAL observatory, most of the sources in this catalog are low-mass X-ray binaries (73 of the 105 sources) and only 18 + 3 are high-mass X-ray binaries and cataclysmic variables. Out of the Galactic sources, there are also the black hole candidate XTE J1652-453, the peculiar X-ray burster XMMJ174457-2850.3, and the soft gamma repeater SGR 1806-20 in the catalog; out of the extragalactic sources, there are three active galactic nuclei and a galaxy cluster (Oph CL). The nature of four sources, including the newly discovered one, still remains unknown. We have constructed the luminosity function for the low-mass X-ray binaries from the catalog and considered other statistical properties of their sample.

    The compact array of the VLA was used to study H I absorption in a 100-pc region in the center of the Galaxy. An absence of gas was observed at 40-50 km/s across the Radio Arc, suggesting that the '40 km/s molecular cloud' possibly associated with Sgr A is placed behind the Arc. At +20 km/s, the observations show absorption by material which could be depolarizing much of the synchrotron emission from the Arc filaments. The kinematic structure revealed by high-resolution molecular and radio recombination line observations is confirmed by the distribution of H I gas at -10 to -60 km/s.

  1. Individual radiation load monitoring in the medical and technical staff of a regional dosimetric center

    International Nuclear Information System (INIS)

    The structure of radiological procedures over the last decade underwent substantial changes that influenced the working conditions of the medical and technical staff of photofluorographic departments. Radiodiagnostic equipment became more powerful. To find a solution to urgent problems of individual dosimetric monitoring there should be organized regional dosimetric centers using methods of thermoluminescent dosimetry. According to the data obtained, the levels of occupational irradiation of the medical and technical staff of photofluorotraphic departments, have a clear tendency to a decrease, and Din most cases do not exceed 0.1 of the MP. Mathematical approximation of the density of annual dose distribution has revealed the stabilization of their maximum and a gradual decrease that attests to the standardization of the working conditions. A collective dose for the staff-members of photofluorographic departments in 1979 was 290 man/rem

    Previously we demonstrated that collisions between clumps of gas in the Circum-Nuclear Disc can reduce their angular momentum and set some of the clumps on a plunging trajectory towards the supermassive black hole. If the central luminosity is determined by the gas accretion mechanism, then there exists a certain range of accretion rate and efficiency that allow the thermal instability to sustain the mass inflow through the two-temperature medium. Here we explore the stellar component of the nuclear star cluster which acts as an additional source of heating and contributes an additional energy input into the gaseous environment in the Galactic center Minispiral region. Under these conditions we discuss the values of relevant parameters that can support or suppress the thermal instability.

    The CMS 2004 Data Challenge (DC04) was devised to test several key aspects of the CMS Computing Model in three ways: by trying to sustain a 25 Hz reconstruction rate at the Tier-0; by distributing the reconstructed data to six Tier-1 Regional Centers (CNAF in Italy, FNAL in US, GridKA in Germany, IN2P3 in France, PIC in Spain, RAL in UK) and handling catalogue issues; by redistributing data to Tier-2 centers for analysis. Simulated events, up to the digitization step, were produced prior to the DC as input for the reconstruction in the Pre-Challenge Production (PCP04). In this paper, the model of the Tier-0 implementation used in DC04 is described, as well as the experience gained in using the newly developed data distribution management layer, which allowed CMS to successfully direct the distribution of data from Tier-0 to Tier-1 sites by loosely integrating a number of available Grid c omponents. While developing and testing this system, CMS explored the overall functionality and limits of each component, i...

    The most characteristic high-energy phenomena in the Galactic center (GC) region is the presence of strong K-shell emission lines from highly ionized Si, S, Ar, Ca, Fe and Ni, which form the Galactic Center X-ray Emission (GCXE). These multiple lines suggest that the GCXE is composed of at least two plasmas with temperatures of ~1 and ~7 keV. The GCXE also exhibits the K-shell lines from neutral Si, S, Ar, Ca, Fe and Ni atoms. A debatable issue is the origin of the GCXE plasma; whether it is a diffuse plasma or integrated emission of many unresolved point sources such as cataclysmic variables and active binaries. Detailed spectroscopy for these lines may provide a reliable picture of the GCXE plasma. The origin of the K-shell lines from neutral atoms is most likely the fluorescence by X-rays from a putative past flare of Sgr A*. Therefore ASTRO-H may provide unprecedented data for the past light curve of Sgr A*. All these lines may provide key information for the dynamics of the GCXE, using possible Doppler s...

    Strong iron fluorescence at 6.4 keV and hard-X-ray emissions from giant molecular clouds in the Galactic center region have been interpreted as reflections of a past outburst of the Sgr A* supermassive black hole. Careful treatment of multiple interactions of photons in a complicated geometry is essential to modeling the reprocessed emissions from the dense clouds. We develop a new calculation framework of X-ray reflection from molecular clouds based on Monte Carlo simulations for accurate interpretation of high-quality observational data. By utilizing this simulation framework, we present the first calculations of morphologies and spectra of the reflected X-ray emission for several realistic models of Sgr B2, which is the most massive molecular cloud in our Galaxy. The morphology of scattered hard X-rays above 20 keV is significantly different from that of iron fluorescence due to their large penetrating power into dense regions of the cloud, probing the structure of the cloud. High-resolution spectra provid...

  7. Estimates of cancer mortality due to the ingestion of mineral spring waters from a highly natural radioactive region of Brazil

    International Nuclear Information System (INIS)

    This study was performed in order to evaluate the lifetime risk of radiation-induced cancer due to the ingestion of 226Ra, 228Ra and 222Rn in mineral spring waters from a highly natural radioactive region of Brazil. Water samples were randomly collected at 10 spring sites located in the Aguas da Prata region. A total of eight radium-induced cancers (four head carcinomas plus four bone sarcomas) per 106 exposed persons were predicted. For radon, a total of 23 cases of fatal stomach cancers per 106 exposed persons were estimated. These predictions suggest that chronic ingestion of radium and radon at the levels observed at these springs will result in incremental increases of fatal cancers of 2 and 0.5%, respectively, above the background incidence rate. The uncertainties in evaluating the carcinogenic effects due to radium and radon ingestion were analyzed. These investigations suggest that the true risk due to radium ingestions is likely to be within an order of magnitude in either direction of the risk estimated in the present paper. (author)

    Full Text Available Introduction: Medical thoracoscopy is a minimally invasive procedure for diagnosing and treating pleural diseases. Despite its proven role in diagnostic and therapeutic purposes, it is infrequently used, which could be because of cost of equipment and lack of training. We analyzed our initial 3 years record of thoracoscopy at Himalayan Institute of Medical Sciences, a tertiary care center in Himalayan region of north India. Materials and Methods: This cross-sectional study was to analyze our experience of medical thoracoscopy which was started in Jan 2011 at our center. All patients who underwent thoracoscopy during the period between Jan 2011 to Dec 2013 were included in the study. Thoracoscopy was performed for diagnosis of undiagnosed pleural effusions. Clinical, radiological, cytological & histopathological data of the patients were collected prospectively and analysed. Results: The diagnostic yield for a pleuroscopic pleural biopsy in our study was 87.23% (41/47. Malignancy was diagnosed histopathologically in 70.2% (33/47 patients (both primary & metastatic pleural carcinoma and tuberculosis in 10.6% (5/47. There was no mortality related to procedure. Only three patients had minor complications like subcutaneous emphysema which was mild and resolved by second post-procedure day. Pain at intercostal drain site was observed in some patients. Conclusion: Thoracoscopy is an easy outpatient procedure and an excellent diagnostic tool for pleural effusion of uncertain etiology. It has low complication rate even in settings where the procedure is just started. It should be included in the armamentarium of tools for management of pleural effusion.

    We report four trigonometric parallaxes for high-mass star-forming regions within 4 kpc of the Galactic center. These measurements were made with the Very Long Baseline Array as part of the BeSSeL Survey. By associating these sources kinematically with large-scale features in CO and H I longitude-velocity diagrams, we begin to outline some major features of the inner Milky Way: the Connecting arm, the near and far 3 kpc arms, and the Norma arm. The Connecting arm in the first Galactic quadrant lies closer to the Galactic center than the far 3 kpc arm and is offset by the long-bar's major axis near its leading edge, supporting the presence of an inner Lindblad resonance. Assuming the 3 kpc arms are a continuous physical structure, the relative Galactocentric distance of its near and far sides suggests highly elliptical streamlines of gas around the bar(s) and a bar corotation radius, r {sub CR} ≳ 3.6 kpc. At a Galactic longitude near 10° and a heliocentric distance of about 5 kpc, the near 3 kpc arm and the Norma arm intersect on a face-on view of our Galaxy, while passing at different Galactic latitudes. We provide an accurate distance measurement to the W 31 star-forming complex of 4.95{sub −0.43}{sup +0.51} kpc from the Sun, which associates it with a bright CO feature belonging to the near 3 kpc arm.

  11. Continuous Regional Arterial Infusion Therapy for Acute Necrotizing Pancreatitis Due to Mycoplasma pneumoniae Infection in a Child

    International Nuclear Information System (INIS)

    A case of acute necrotizing pancreatitis due to Mycoplasma pneumoniae infection was treated in an 8-year-old girl. She experienced acute pancreatitis during treatment for M. pneumoniae. Contrast-enhanced computed tomographic scan revealed necrotizing pancreatitis. The computed tomographic severity index was 8 points (grade E). A protease inhibitor, ulinastatin, was provided via intravenous infusion but was ineffective. Continuous regional arterial infusion therapy was provided with gabexate mesilate (FOY-007, a protease inhibitor) and meropenem trihydrate, and the pancreatitis improved. This case suggests that infusion therapy is safe and useful in treating necrotizing pancreatitis in children.

    Full Text Available Information centers are duly obliged to move in line with their parent organizations’ goals and missions in creating knowledge. In the age of information and communication revolution, and in a knowledge-based economy, organizations that are involved in creation of knowledge have an important role in communication and diffusion of knowledge. In the mean time, libraries and information centers change from being mere depository sources to knowledge institutions. The current research aimed to study the present state of knowledge management infrastructures of the Regional Information Center for Science and Technology (RICeST as a national and regional information center. The statistic population of this study was consisted of 87 staff. Data was collected by means of questionnaires, observation and interviews. The results showed the required infrastructure for KM activities were almost there, among different aspects of which, budgeting had a better situation in the institution under study. In regards with establishment of knowledge management, RICeST was paying more attention to information and communication technology and knowledge network via applications such as the Internet and extranets. Another fact was that in the RICeST, emphasis was on learning and on human resources as the substantial sources in creation of knowledge. Among other aspects, “organizational culture” was in a lower state compared with other aspects in the RICeST.

    The goal of NICCR (National Institute for Climatic Change Research) was to mobilize university researchers, from all regions of the country, in support of the climatic change research objectives of DOE/BER. The NICCR Midwestern Regional Center (MRC) supported work in the following states: North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Minnesota, Iowa, Missouri, Wisconsin, Illinois, Michigan, Indiana, and Ohio. The MRC of NICCR was able to support nearly $8 million in climatic change research, including $6,671,303 for twenty projects solicited and selected by the MRC over five requests for proposals (RFPs) and $1,051,666 for the final year of ten projects from the discontinued DOE NIGEC (National Institute for Global Environmental Change) program. The projects selected and funded by the MRC resulted in 135 peer-reviewed publications and supported the training of 25 PhD students and 23 Masters students. Another 36 publications were generated by the final year of continuing NIGEC projects supported by the MRC. The projects funded by the MRC used a variety of approaches to answer questions relevant to the DOE’s climate change research program. These included experiments that manipulated temperature, moisture and other global change factors; studies that sought to understand how the distribution of species and ecosystems might change under future climates; studies that used measurements and modeling to examine current ecosystem fluxes of energy and mass and those that would exist under future conditions; and studies that synthesized existing data sets to improve our understanding of the effects of climatic change on terrestrial ecosystems. In all of these efforts, the MRC specifically sought to identify and quantify responses of terrestrial ecosystems that were not well understood or not well modeled by current efforts. The MRC also sought to better understand and model important feedbacks between terrestrial ecosystems, atmospheric chemistry, and regional

    When developing response plans in the aftermath of a catastrophic incident, jurisdictions often fail to conduct the necessary interdisciplinary planning needed to fully address the needs across jurisdictional borders. The Purdue Homeland Security Institute (PHSI) was selected by the City of Chicago Office of Emergency Management and Communications (OEMC) in 2010 to lead an effort to address planning across jurisdictional borders during mass evacuations following a catastrophic incident. Specifically, PHSI was chosen to lead the effort in developing a planning and implementation guide for standing up a conceptual Regional Hub Reception Center (RHRC). A major component within the mass evacuation and sheltering continuum, the RHRC is designed to provide evacuees with quickresponse mass care and emergency assistance while their other needs are assessed and appropriate shelter locations are identified. The RHRC also provides a central location to leverage governmental, nongovernmental, and private sector resources and is the first point in the evacuation, mass care, and sheltering concept of operations where more comprehensive support (food, shelter, medical, psychological, household pet sheltering, reunification, etc) can be expected. PHSI undertook this lead role working within the Illinois-Indiana-Wisconsin (IL-IN-WI) Combined Statistical Area (CSA) as part of the US Department of Homeland Security Regional Catastrophic Planning Grant Program. Coordinating closely with the City of Chicago OEMC and IL-IN-WI CSA Regional Catastrophic Planning Team, PHSI lead the research effort using resource and capability data compiled from all 17 jurisdictions within the IL-IN-WI CSA and validated the RHRC concept using three tabletop exercises. Upon completion, the PHSI team published the RHRC planning guide complete with procedures and processes that define the roles and responsibilities of government, nongovernment organizations, and private sector for providing RHRC mass care

  16. Atomistic mechanisms of strain relaxation due to ductile void growth in ultrathin films of face-centered-cubic metals

    International Nuclear Information System (INIS)

    A comprehensive computational analysis is reported of the atomistic mechanisms of strain relaxation and failure in free-standing Cu thin films under applied biaxial tensile strain for strain levels up to 6%. The analysis focuses on nanometer-scale-thick films with a preexisting void extending across the film thickness and the film plane oriented normal to the [111] crystallographic direction. Our computational study is based on isothermal-isostrain large-scale molecular-dynamics simulations within an embedded-atom-method parametrization for Cu. Our analysis has revealed various regimes in the film's mechanical response as the applied strain level increases. Within the considered strain range, after an elastic response at a low strain (<2%), void growth is the major strain relaxation mechanism mediated by the emission of perfect screw dislocation pairs from the void surface and subsequent dislocation propagation; as a result, a plastic zone forms around the void. Plastic deformation is accompanied by the glide motion of the dislocations emitted from the void surface, void surface morphological transitions, formation of a step pattern on the film's surfaces, dislocation jogging, vacancy generation due to gliding jogged dislocations, dislocation-vacancy interactions, vacancy pipe diffusion along dislocation cores, as well as dislocation-dislocation interactions. The increase in film surface roughness with increasing strain eventually leads to nucleation and propagation from the film surfaces of threading dislocation loops, which ultimately break up when they reach the opposite free surface of the thin film

    Module-embedded power electronics developed by Maxim Integrated are under evaluation through a partnership with the Department of Energy's Regional Test Center (RTC) program. Field deployments of both conventional modules and electronics-enhanced modules are designed to quantify the performance advantage of Maxim's products under different amounts of interrow shading, and their ability to be deployed at a greater ground-coverage ratio than conventional modules. Simulations in PVSYST have quantified the predicted performance difference between conventional modules and Maxim's modules from interrow shading. Initial performance results have identified diffuse irradiance losses at tighter row spacing for both the Maxim and conventional modules. Comparisons with published models show good agreement with models predicting the greatest diffuse irradiance losses. At tighter row spacing, all of the strings equipped with embedded power electronics outperformed their conventional peers. An even greater performance advantage is predicted to occur in the winter months when the amount of interrow shading mismatch is at a maximum.

    We present the results of a Suzaku study of a bright point-like source in the 6.7 keV intensity map of the Galactic center region. We detected an intense FeXXV 6.7 keV line with an equivalent width of ~1 keV as well as emission lines of highly ionized Ar and Ca from a spectrum obtained by the X-ray Imaging Spectrometer. The overall spectrum is described very well by a heavily absorbed (~2x10^{23}cm^{-2}) thin thermal plasma model with a temperature of 3.8+/-0.6 keV and a luminosity of ~3x10^{34} erg s^{-1} (2.0--8.0 keV) at 8 kpc. The absorption, temperature, luminosity, and the 6.7 keV line intensity were confirmed with the archived XMM-Newton data. The source has a very red (J-Ks=8.2 mag) infrared spectral energy distribution (SED), which was fitted by a blackbody emission of ~1000 K attenuated by a visual extinction of ~31 mag. The high plasma temperature and the large X-ray luminosity are consistent with a wind-wind colliding Wolf-Rayet binary. The similarity of the SED to those of the eponymous Quintuple...

  20. Regional radiation protection center in the Federal Republic of Germany - Tasks and Organization

    International Nuclear Information System (INIS)

    In the Federal Republic of Germany 220,000 staff members are classified at the moment as occupationally radiation exposed persons. For the maintenance of industrial health and safety for the workers in the companies and for the medical, professional and social rehabilitaion after an accident the so-called ''Berufsgenossenschaften'' (professional trade associations) are responsible. For employees in nuclear industry two trade associations are competent: - the Trade Association for Precision Engineering and Electrical Engineering for the 6,000 employees in nuclear power plants, - the Trade Association of the Chemical Industry for the 4,000 employees in fuel element fabrication and the reprocessing companies. In case of an accident workers from service companies e.g. construction and installation companies could be affected as well. Therefore these trade associations have founded a couple of years ago an ''Institute for Radiation Protection''. A special task of this institute is First Aid to overexposed people in case of radiation accidents. In addition, it organizes the 24-hours-service of the seven Regional Radiation Protection Centers of Federal Republic of Germany. The institute provides special training of radiation protection physicians and occupationally radiation exposed persons. (author)

    Full Text Available OBJECTIVE:This study assessed the prevalence of scoliosis and the patterns of scoliotic curves in patients with Williams-Beuren syndrome. Williams-Beuren syndrome is caused by a chromosome 7q11.23 deletion in a region containing 28 genes, with the gene encoding elastin situated approximately at the midpoint of the deletion. Mutation of the elastin gene leads to phenotypic changes in patients, including neurodevelopmental impairment of varying degrees, characteristic facies, cardiovascular abnormalities, hypercalcemia, urological dysfunctions, and bone and joint dysfunctions.METHODS:A total of 41 patients diagnosed with Williams-Beuren syndrome, who were followed up at the genetics ambulatory center of a large referral hospital, were included in the study. There were 25 male subjects. The patients were examined and submitted to radiographic investigation for Cobb angle calculation.RESULTS:It was observed that 14 patients had scoliosis; of these 14 patients, 10 were male. The pattern of deformity in younger patients was that of flexible and simple curves, although adults presented with double and triple curves. Statistical analysis showed no relationships between scoliosis and age or sex.CONCLUSION:This study revealed a prevalence of scoliosis in patients with Williams-Beuren syndrome of 34.1%; however, age and sex were not significantly associated with scoliosis or with the severity of the curves.

    Full Text Available Background: Palliative radiotherapy (PRT is the eventual requirement in 30-50% of all cancer patients. PRT is primarily aimed to relieve pain and prevent/treat collapse or fracture in case of bone metastasis, to reduce edema in patients with cranial metastasis, and to control distressing symptoms of rapid primary growth. An audit of PRT planned in a busy cancer center can help in the characterization of the requirements of the patients and the formulation of institutional policies. Materials and Methods: In total, 516 patients who received PRT in our regional cancer center from January 2012 to December 2012 and whose complete records were available for analysis were selected for this retrospective study. Medical records and radiotherapy files were analyzed to obtain data such as sociodemographic parameters, prescription of PRT, and follow up. Descriptive statistics were evaluated in terms of frequencies and percentages to allow comparisons. Results: Of the 516 patients, 73% patients were male; the median age of the patients receiving PRT was 62 years (range 13-83 years. About 48% ( n = 248 patients received PRT at the primary site while rest (52% were given PRT at the metastatic site. The most common indication of PRT was pain (56.8% cases, followed by cytostatic PRT (19.8% and raised ICT (12.4%. The median dose prescribed was 30 Gy (range 8-36 Gy delivered in 1-12 fractions over the duration of 1-18 days. The overall response rate was about 43% at 2 weeks of completion of PRT; the median follow-up of the patients was 154 days (range 9-256 days. The long-term symptom relief at median follow up was 8%. Conclusions: Good clinical judgment and expertise is required in prescribing correct fractionation schedule to achieve effective symptom palliation with lowest possible cost and inconvenience to the patients and relatives. Hypofractionated radiotherapy is a feasible treatment option in patients with advanced incurable disease to achieve effective

  5. Increased intestinal marker absorption due to regional permeability changes and decreased intestinal transit during sepsis in the rat

    International Nuclear Information System (INIS)

    The intestinal barrier properties are impaired during inflammation and sepsis, but the mechanisms behind this are unknown and were therefore investigated during experimental sepsis in rats. The different-sized intestinal absorption markers 51Cr-labeled ethylenediaminetetraacetic acid (EDTA) and ovalbumin were gavaged to rats made septic by intra-abdominal bacterial implantation and to sham-operated rats. Regional tissue permeability was measured in diffusion chambers, and intestinal transit was evaluated by intestinal accumulation of gavaged 51Cr-EDTA. In comparison with the sham-operated rats, septic rats had higher 51Cr-EDTA levels in blood and urine and showed a prolonged intestinal transit. Septic rats also had a lower tissue permeability to both markers in the small intestines but higher permeability to ovalbumin in the colon. Rats receiving morphine to decrease intestinal motility showed similar changes, with a decreased intestinal transit and increased marker absorption. Thr results suggest that the increased intestinal absorption during sepsis was due to regional permeability changes and prolonged intestinal transit. 38 refs., 4 figs., 2 tabs

  6. Supercurrent unbalance due to in-plane asymmetry of defected regions with respect to the sample geometry

    International Nuclear Information System (INIS)

    A modulation of the supercurrent distribution in superconductors results in a long-range disturbance due to the strong nonlinearity of the constitutive relation between electric field and current density in the superconducting state. Here we present the relevant cases of local modulations of the superconducting properties in thin specimens, with asymmetric positioning of the modulated region with respect to the sample geometry, but retaining the same shape of the sample itself. The local modulation, that induces the long-range disturbance of the superconducting condensate, is produced, in our case, either by a vanishing order parameter, a void, or by nanostructured defects, with finite values of the order parameter. In the latter case, local structural modulation on the nanometric scale were produced in microscopic areas by confined high-energy irradiation with heavy ions. The quantitative magneto-optical analysis directly reveals the local supercurrent distribution and thus the features of the long-range disturbance. A novel phenomenology in presence of these asymmetric supercurrent modulations is observed, such as supercurrent unbalance effects (in dependence on the incidence angle of the current density, with respect to the defect interface, and on the external magnetic field), and a pattern transition in the vortex state of the modulated region

    The effect on climate due to seasonal variation of vegetation and roughness length was simulated in Part I of this essay. In Part II, the individual effect of albedo and the joint effect of all those factors (vegetation, roughness length and albedo) were calculated by numerical sensitivity experiments. The results showed that: (1) There is no significant effect on precipitation if the albedo of 4 seasons is used to replace the CRCM's climate average data, but the effect on land surface temperature can be seen clearly. And the effect also can be seen in adjacent regions. (2) If all these three factors are used to replace the CRCM's climate average data at the same time, the effect on precipitation is significant, the most variation value is 300 mm. And the effect on temperature is similar to what we can see if only one of these factors in CRCM is replaced by monthly or seasonal data. (3) Seasonal variation of land surface parameters has important effect not only on regional climate, but also on global environment.

  8. Regional myocardial extraction of a radioiodinated branched chain fatty acid during right ventricular pressure overload due to acute pulmonary hypertension

    International Nuclear Information System (INIS)

    To determine whether branched chain fatty acid extraction is reduced during right ventricular (RV) dysfunction due to acute pulmonary artery hypertension, studies were done in 6 anesthetized dogs. Regional branched chain fatty acid extraction was measured by comparing the myocardial uptake of I-125 labeled 15-[p-(iodophenyl)]-3-methylpentadecanoic acid (I-PDA) to myocardial blood flow. Acute pulmonary hypertension was induced by incremental intravenous injection of 100 micron diameter glass beads into six pentobarbital anesthetized, mechanically ventilated dogs. Myocardial blood flow was measured by radiolabeled microspheres both under baseline conditions and during pulmonary hypertension. Mean RV pressure rose from 12 +- 2 (mean +- SEM) to 30 +-3mmHg resulting in a 225 +- 16% increase in RV stroke work. RV ejection fraction, as assessed by gated blood pool scans fell from 39 +- 2 to 18 +- 2%. Left ventricular (LV) pressures, stroke work and ejection fraction were unchanged. Myocardial blood flow increased 132 + 59% in the RV free wall and 67 +- 22% in the RV septum. LV blood flow was unchanged. Despite increased RV work and myocardial blood flow, no differences were noted in the branched chain fatty acid extraction ratios among LV or RV free walls or septum. The authors conclude that early RV dysfunction associated with pulmonary artery hypertension is not due to inadequate myocardial blood flow or branched chain fatty acid extraction

  9. NOx production due to energetic particle precipitation in the MLT region - results from an ion-chemistry model

    Nieder, Holger; Sinnhuber, Miriam

    2013-04-01

    The chemistry in the mesosphere/lower thermosphere (MLT) region is driven by forcing from solar radiation and energetic particles. The resulting ionisation, dissociation and excitation of the constituents lead to production of neutral reactive species such as NOx (N, NO, NO2) and HOx (H, OH, HO2), both directly from dissociation of neutrals and indirectly from subsequent ion-neutral reactions. As NOx is long-lived during polar winter, it can be transported down to the stratosphere and contribute to catalytic ozone depletion. To study the effective NOx production rates during an ionisation event, runs with a one-dimensional state-of-the-art ion chemistry model (UBIC) are carried out and analysed. The model starts with a neutral atmosphere and uses direct ion and neutral production rates from Porter et al. (1976) and Rusch et al. (1981), adapted for the MLT region. Including raw ionisation rates from external sources such as AIMOS is possible. The ion-neutral reactions in the charged atmosphere are computed until equilibrium is reached, resulting in an effective production rate including impact of ion-neutral reactions. The indirect NOx production rate is found to depend on atmospheric parameters such as pressure, temperature and the abundance of NOx, atomic oxygen and H2O. For the MLT region, this leads to an increasing amount of NOx per ionpair created with increasing altitude due to an increasing atomic oxygen VMR. Values of >1.8 NOx per ionpair can be obtained. The results are made available to a 3D Chemistry Transport Model using a database-approach and multilinear interpolation for readout. Efficiency of this approach and first results from a 3D CTM using the ion-chemistry results are discussed.

    The distributive pattern of disaster due to severe climate events over the coast of West Africa especially Nigeria was examined using yearly mean disaster due to severe climatic events for the period of 30 years (1981-2010) from the marine stations in the coastal region of Nigeria. Graphical and isohyetal analyses were used to look into the patter of severe weather events over the area considered and to see if the severe weather events is increasing or not in the coast of West Africa especially the Nigerian coast and how to mitigate ,were policy relating to severe weather events are discussed. The paper conclude that due to the nature of coast of West Africa and Nigeria in particular, it enjoys longer severe weather events season than dry during the wet season, it is common to observe periods of enhanced or suppressed convective activity to persist over the wide areas for somedays. This paper also contributes to the wealth of knowledge already existing on Indigenous people play major roles in preserving the ecosystem especially during severe weather events . This has resulted in the recent calls for the integration of indigenous knowledge systems into global knowledge system strategies. Until now, integrating local knowledge systems into severe weather events and climate change concerns is not a completely new idea. A comprehensive review of literature using electronic and non-electronic databases formed the methodology. The paper conclude also by drawing the attention that by targeting Promoting indigenous people's participation in severe weather events and climate change issues is an important initiative towards adaptation and sustainable development in Africa and around the world. It is increasingly realized that the global knowledge system has dominated research, policies and programmes that address current severe weather events and climate change's challenges,mitigation and adaptation strategies.

    Full Text Available Over 50% of Tula Region areas were contaminated after the Chernobyl NPP accident. The article provides the thirty years’ results of radiation hygienic monitoring of the Chernobyl accidental fallout - affected areas in Tula Region. The radiation situation is assessed at the initial accidental period and at the current stage. The initial levels of gamma - radiation dose intensity (up to 35 mcSv/hr are identified for the period of the “iodine” hazard along with the tabular data on the dose intensity relative stabilization by the beginning of August 1986 due to iodine-131 decay. The information is presented regarding iodine-131 tentative maximum permissible level exceedance in the dairy products of the two most contaminated regional areas - Plavskoye and Arsenievskoye. The article also provides the laboratory data on the total beta - activity in the foodstuffs in 1986-1987 and cesium-137 maximum permissible level exceedence in 1986. The radionuclide maximum permissible level exceedances in foodstuffs were registered only in 1986 due to the plants surface contamination whereas in the forest mushrooms those exceedances were repeatedly found until 2004. The black earths and grey forest soils had a benign impact upon the intensity of the radionuclide transfer into plants which resulted in the formation of internal radiation doses.At the current stage, the content of cesium-137 and strontium- 90 in the foodstuffs can only be quantified by a radiochemical method. The table covers all the districts within the boundaries of radiation contaminated zones. The radiochemical studies indicate the main dose - forming products. The article contains the table of internal and external radiation doses of the population in Plavsk town over 1986-1990 and displays the factors impacting population’s internal and external exposure. The Chernobyl - affected exposure dose of the population is mostly attributed to the external radiation and, for over twenty years, it

    2013-10-01

    Full Text Available The aim of the paper is to estimate Krasnoyarsk region budget losses due to the shortfalls of taxes from businesses related with a temporary disability of smoking employees and the reduction of labor intensity due to the smoking breaks in 2011.In our work we used the method of economic losses estimation, developed by Conference Board of Canada.The following results were obtained. The estimation of tax shortfalls due to a temporary disability of smoking employees and decrease of labor intensity due to smoking breaks was carried out. It was obtained that Krasnoyarsk region budget losses as a result of the tax shortfalls are equal to 532.8 million rubles – due to increased sick absence risks among smokers and 3 414.3 million rubles – due to the lack of workers on the workplace during smoking breaks. Thus, it was found that the total budget losses of Krasnoyarsk region in 2011 reach 0.34% of the gross regional product.The obtained results can be used for the assessments of the economic losses.DOI: http://dx.doi.org/10.12731/2218-7405-2013-7-22

    2013-10-01

    In this paper we calculated soil carbon stocks in Brazil studying 17 paired sites where soil stocks were determined in native vegetation, pastures and crop-livestock systems (CPS), and in other regional samplings encompassing more than 100 pasture soils, from 6.58 to 31.53° S, involving three major Brazilian biomes: Cerrado, Atlantic Forest, and the Pampa. The average native vegetation soil carbon stocks at 10, 30 and 60 cm soil depth were equal to approximately 29, 64, and 92 Mg ha-1, respectively. In the paired sites, carbon losses of 7.5 Mg ha-1 and 11.6 Mg ha-1 in CPS systems were observed at 10 cm and 30 cm soil depths, respectively. In pasture soils, carbon losses were similar and equal to 7.5 Mg ha-1 and 11.0 Mg ha-1 at 10 cm and 30 cm soil depths, respectively. Differences at 60 cm soil depth were not significantly different between land uses. The average soil δ13C under native vegetation at 10 and 30 cm depth were equal to -25.4‰ and -24.0‰, increasing to -19.6‰ and -17.7‰ in CPS, and to -18.9‰, and -18.3‰ in pasture soils, respectively; indicating an increasing contribution of C4 carbon in these agrosystems. In the regional survey of pasture soils, the soil carbon stock at 30 cm was equal to approximately 51 Mg ha-1, with an average δ13C value of -19.67‰. Key controllers of soil carbon stock in pasture sites were sand content and mean annual temperature. Collectively, both could explain approximately half of the variance of soil carbon stocks. When pasture soil carbon stocks were compared with the average soil carbon stocks of native vegetation estimated for Brazilian biomes and soil types by Bernoux et al. (2002) there was a carbon gain of 6.7 Mg ha-1, which is equivalent to a carbon gain of 15% compared to the carbon soil stock of the native vegetation. The findings of this study are consistent with differences found between regional comparisons like our pasture sites and plot-level paired study sites in estimating soil carbon stocks

    Mountain regions are characterized by pronounced heterogeneity resulting from a wide range of altitude gradients, topography and specific microclimate. In these areas natural hazards are emphasized and additional anthropogenic activities have a catalytic effect on the degradation processes. Land use change for touristic and recreational purposes, results in the creation of artificial landscape elements that disturb the landscape structure. Skiing as a type of tourist and recreational activity strongly influences the land cover, changing the dynamics of natural ecosystems. Initially, ski resorts provoke intensive erosion processes, affecting the surrounding environment and even endangering the functionality of the built objects. The dominant disturbing activities (clear cuttings, trunk transport, machine grading of slopes, huge excavations, and access road construction) are followed by the activities during skiing and non skiing periods (skiing, usage of snow groomers, moving of vehicles and tourists, forestry activities and overgrazing). On a landscape scale, the impact of the ski resorts broadens to larger areas, which is accompanied by the degradation of the landscape visual quality. Due to the technical characteristics of the ski slopes, their volume and linear distribution evoke strong contrast in the scenery (geometrical versus bimorph edges). Such areas are losing their scenic quality and visual identity, and as such can be considered anthropogenic. The applied restoration and erosion control measures have stopped the degradation processes and helped to rehabilitate the appearance and functions of the landscape. The results of this investigation can contribute to the improvement of planning processes and the implementation of development projects in ski areas.

    Among the main greenhouse gases (CO2, CH4 and N2O), N2O has the highest global warming potential. N2O emission is mainly connected to agricultural activities, increasing as nitrogen concentrations increase in the soil with nitrogen fertilizer application. We evaluated N2O emissions due to application of increasing doses of ammonium nitrate and urea in two sugarcane fields in the mid-southern region of Brazil: Piracicaba (São Paulo state) and Goianésia (Goiás state). In Piracicaba, N2O emissions exponentially increased with increasing N doses and were similar for urea and ammonium nitrate up to a dose of 107.9 kg ha-1 of N. From there on, emissions exponentially increased for ammonium nitrate, whereas for urea they stabilized. In Goianésia, N2O emissions were lower, although the behavior was similar to that at the Piracicaba site. Ammonium nitrate emissions increased linearly with N dose and urea emissions were adjusted to a quadratic equation with a maximum amount of 113.9 kg N ha-1. This first effort to measure fertilizer induced emissions in Brazilian sugarcane production not only helps to elucidate the behavior of N2O emissions promoted by different N sources frequently used in Brazilian sugarcane fields but also can be useful for future Brazilian ethanol carbon footprint studies.

  18. Assessment of radiological effects on the regional environment due to the operation of the Tokai Reprocessing Plant

    International Nuclear Information System (INIS)

    The regional environmental radiological effects were assessed for the past 25-year operation of the Tokai Reprocessing Plant (TRP). The assessment was basically performed with the environmental radiological monitoring data around the TRP. For the environmental monitoring, various kinds of terrestrial and marine samples including air dust, surface soil, polished rice grain, leafy vegetable, milk, seawater, seabed sediments, fish, shellfish and seaweed were collected in the surrounding environment of the TRP. Radionuclides such as 3H, 14C, 90Sr, 137Cs and 239,240Pu in the environmental samples were determined by radiochemical methods. However, they showed no significant short-term increase or long-term accumulation of radionuclides discharged from the TRP. Therefore, the public dose was evaluated using the mathematical models and the discharge data of radionuclides. The estimated annual effective dose for the public was about 0.1% of the annual effective dose limit recommended by the ICRP. The assessment showed that there were no significant radiological effects on the environment and the public due to the 25-year operation of the TRP

  19. Intake of uranium and radium-226 due to food crops consumption in the phosphate region of Pernambuco - Brazil

    International Nuclear Information System (INIS)

    The phosphate region located in the Northeast of Brazil covers an area of approximately 150 km long with an average width of 4 km, along the coast of the states of Pernambuco and Paraiba. The inhabitants of this area are exposed to natural radioactivity levels higher than the background values recorded in the literature, mainly due to the presence of uranium and its decay products in the phosphatic sediments. The main aim of this study was to determine the activity concentration of uranium and 226Ra in foodstuffs cultivated in this area, where the phosphate mineral has been extracted. The activity concentrations found for uranium and 226Ra in the foodstuffs analyzed varied from 13 to 186 mBq kg-1 (wet weight), with a mean value of 46 mBq kg-1 and from 43 to 2209 mBq kg-1 (wet weight), with a mean value of 358 mBq kg-1, respectively. The annual intake of these radionuclides, for rural residents, was 7.45 Bq for uranium and 69.3 Bq for 226Ra

    We present imaging at 19, 25, 31, and 37 {\\mu}m of the compact HII region complex G-0.02-0.07 located 6 pc in projection from the center of the Galaxy obtained with SOFIA using FORCAST. G-0.02-0.07 contains three compact HII regions (A, B, and C) and one ultra-compact HII region (D). Our observations reveal the presence of two faint, infrared sources located 23'' and 35'' to the east of region C (FIRS 1 and 2) and detect dust emission in two of the three "ridges" of ionized gas west of region A. The 19/37 color temperature and 37 {\\mu}m optical depth maps of regions A - C are used to characterize the dust energetics and morphology. Regions A and B exhibit average 19/37 color temperatures of ~105 K, and regions C and D exhibit color temperatures of ~115 K and ~130 K, respectively. Using the DustEM code we model the SEDs of regions A - D and FIRS 1, all of which require populations of very small, transiently heated grains and large, equilibrium-heated grains. We also require the presence of polycyclic aromatic ...

    Recent observations of the Galactic center in high-energy gamma-rays (above 0.1TeV) have opened up new ways to study this region, from understanding the emission source of these high-energy photons to constraining the environment in which they are formed. We present a revised theoretical density model of the inner 5pc surrounding Sgr A* based on the fact that the underlying structure of this region is dominated by the winds from the Wolf-Rayet stars orbiting Sgr A*. An ideal probe and application of this density structure is this high energy gamma-ray emission. We assume a proton-scattering model for the production of these gamma-rays and then determine first whether such a model is consistent with the observations and second whether we can use these observations to further constrain the density distribution in the Galactic center.

    With the aim of studying the endoparasite fauna of horses from the Formiga city, located in center-west region of the state of Minas Gerais, 25 animals that were naturally infected with helminths were evaluated. By means of parasitological necropsies, different endoparasites were found. The subfamily Cyathostominae presented the highest incidence, followed by Trichostrongylus axei, Oxyuris equi, Triodontophorus serratus, Strongyloides westeri, Strongylus edentatus, Habronema muscae, Parascaris equorum, Probstmayria vivipara, Strongylus vulgaris, Gasterophilus nasalis, Anoplocephala magna and Anoplocephala perfoliata. In the present study, if the species Probstmayria vivipara was not considered in the prevalence, the frequency of Cyathostominae was equivalent to 94.85%. The results obtained in this study allowed us to detect and identify different species of helminths in horses, and confirmed the high incidence of nematodes belonging to the subfamily Cyathostominae in the center-west region of Minas Gerais.

We describe the setup of an automatic quality control system for the crystal measurements and the present results on their qualification, as well as the REDACLE project, which has been developed to control and ease the production process. As it will not be possible to precalibrate the whole calorimeter,the crystal measurements and quality checks performed at the Regional Center will be crucial to provide a basis for fast in-situ calibration with particles. REDACLE is at the same time a fast database and a data management system, where the database and the workflow structures are decoupled, in order to obtain the best flexibility.

    Full Text Available With the aim of studying the endoparasite fauna of horses from the Formiga city, located in center-west region of the state of Minas Gerais, 25 animals that were naturally infected with helminths were evaluated. By means of parasitological necropsies, different endoparasites were found. The subfamily Cyathostominae presented the highest incidence, followed by Trichostrongylus axei, Oxyuris equi, Triodontophorus serratus, Strongyloides westeri, Strongylus edentatus, Habronema muscae, Parascaris equorum, Probstmayria vivipara, Strongylus vulgaris, Gasterophilus nasalis, Anoplocephala magna and Anoplocephala perfoliata. In the present study, if the species Probstmayria vivipara was not considered in the prevalence, the frequency of Cyathostominae was equivalent to 94.85%. The results obtained in this study allowed us to detect and identify different species of helminths in horses, and confirmed the high incidence of nematodes belonging to the subfamily Cyathostominae in the center-west region of Minas Gerais.

    Full Text Available Ukraine is a leader in Europe in the prevalence of HIV infection. There are up to 270 thousand people, who are living with HIV. Since 1987, in Ukraine, 33,149 HIV-infected people died. During the first six months of 2013, of all the dead, who were suffering from HIV and in need of antiretroviral treatment (ART at the time of death, 41% received treatment and only 5.7% received ART for more than one year. Specialists of Kiev Regional AIDS Center analyzed mortality among the patients of the centre, in order to determine the most frequent cause of death, set the group most at risk and to develop effective measures to reduce mortality among HIV-infected patients. In Kiev AIDS Center, 10,000 people are under medical observation and 4004 of them are taking ART. During 2013, 305 persons died: 217 were women and 88 were men which included 3 children under 14 years. Most of the dead – 272 (89% were aged 25–49. Among the total number of the dead, 125 people (41% were receiving ART, 53 of them (17% were receiving ART for at least one year and 39 of them (13% were receiving ART for less than one month. Hundred and fifty-eight people (52% required ART and 22 (7% did not need therapy. Hundred and ninety-two patients (63% were in four clinical stage of HIV infection. Hundred and ten of them had HIV+TB co-infection. Twenty patients died due to TB and 12 patients died due to hepatitis b virus/hepatitis c virus (HBV/HCV. Among these patients, 87 people (39% were taking ART and 136 persons (61% were in need of ART, but did not get it. Nineteen patients were diagnosed with cancer. Sixteen patients, who were co-infected HIV+TB had a CD4 cell count of more than 300. Based on this analysis, we can conclude that the main causes of high mortality among HIV-infected patients in 2013 were late diagnosis of HIV, besides a large number (52% of patients, who were in need of ART did not take it. A large number (40% among those who died were patients co-infected with HIV

    2016-01-01

    The proposal for a PeVatron in the Galactic Center from the recent multi-TeV measurements of HESS triggers the search for neutrinos from this source. We check that the absorption of gamma-rays in our Galaxy is not relevant at the measured energies, except perhaps for the gamma coming from the very Center. We derive precise upper limits on neutrinos fluxes. The expected number of events for ANTARES, IceCube and KM3NeT are calculated. We conclude that km-cube-class telescopes in the Northern hemisphere can check existence of a hadronic PeV galactic accelerator and have the potential of identifying for the first time one source of high energy neutrinos.

    We compare the results of a small region from our 3.6 - 8.0 micron Spitzer/IRAC imaging survey of 2 x 1.5 deg around the Galactic Center with x-ray and radio emission due to high energy processes. The region we studied covers 100 x 100 parsecs, and was chosen to include a rich collection of sources, including Sgr A* and the bright Sgr AWest infrared/radio source complex, the non-thermal radio filaments and the thermal: radio arches. In a 40 x 40 parsec subset of that region we also make a preliminary analysis of the correlation between approx.2300 x-ray sources identified by Muno et al. (2003) and 20,000 infrared sources from our survey. We also investigate the correlation between infrared and radio emission in the large-scale structures including the thermal radio arches and non-thermal radio filaments. We set constrictions on the synchrotron spectrum observed at radio and millimeter wavelengths extrapolated to 8 micons, and set limits on the midinfrared variability of Sgr A* during and after the coordinated multi-wavelength observing campaign in September 2004.

  12. Loss of an iridium-192 source and therapy misadministration at Indiana Regional Cancer Center, Indiana, Pennsylvania, on November 16, 1992

    International Nuclear Information System (INIS)

    On December 1, 1992, the Indiana Regional Cancer Center reported to the US Nuclear Regulatory Commission's (NRC) Region I that they believed a 1.37 E + 11 becquerel (3.7-curie) iridium-192 source from their Omnitron 2000 high dose rate remote brachytherapy afterloader had been found at a biohazard waste transfer station in Carnegie, Pennsylvania. After notifying the NRC, this cancer center, one of several operated by the licensee, Oncology Services Corporation, retrieved the source, and Region I dispatched an inspector and a supervisor to investigate the event. The source was first detected when it triggered radiation alarms at a waste incinerator facility in. Warren, Ohio. The licensee informed the NRC that the source wire had apparently broken during treatment of a patient on November 16, 1992, leaving the source in the patient. On the basis of the seriousness of the incident, the NRC elevated its response to an Incident Investigation. The Incident Investigation Team initiated its investigation on December 3, 1992. The investigation team concluded that the patient received a serious misadministration and died on November 21, 1992, and that over 90 individuals were exposed to radiation from November 16 to December 1, 1992. In a press release dated January 26, 1993, the Indiana County Coroner stated that the cause of death listed in the official autopsy report was ''Acute Radiational Exposure and Consequences Thereof'' An almost identical source wire failure occurred with an afterloader in Pittsburgh, Pennsylvania, on December 7, 1992, but with minimal radiological consequences. This incident was included in the investigation. This report discusses the Omnitron 2000 high dose rate afterloader source-wire failure, the reasons why the failure was not detected by Indiana Regional Cancer Center, the potential consequences to the patient, the estimated radiological doses to workers and the public, and regulatory aspects associated with this incident

    Black carbon (BC) is an important atmospheric aerosol constituent that affects the climate by absorbing (directly) the sunlight and modifying cloud characteristics (indirectly). Here, we present first time yearlong measurements of BC and carbon monoxide (CO) from an urban location of Guwahati located in the Brahmaputra River valley (BRV) in the northeast region of India from 1st July 2013 to 30th June 2014. Daily BC concentrations varied within the range of 2.86 to 11.56μgm(-3) with an annual average of 7.17±1.89μgm(-3), while, CO varied from 0.19 to 1.20ppm with a mean value of 0.51±0.19ppm during the study period. The concentrations of BC (8.37μgm(-3)) and CO (0.67ppm) were ~39% and ~55% higher during the dry months (October to March) than the wet months (April to September) suggesting that seasonal changes in meteorology and emission sources play an important role in controlling these species. The seasonal ΔBC/ΔCO ratios were highest (lowest) in the pre-monsoon (winter) 18.1±1.4μgm(-3)ppmv(-1) (12.6±2.2μgm(-3)ppmv(-1)) which indicate the combustion of biofuel/biomass as well as direct emissions from fossil fuel during the pre-monsoon season. The annual BC emission was estimated to be 2.72Gg in and around Guwahati which is about 44% lower than the mega city 'Delhi' (4.86Gg). During the study period, the annual mean radiative forcing (RF) at the top of the atmosphere (TOA) for clear skies of BC was +9.5Wm(-2), however, the RF value at the surface (SFC) was -21.1Wm(-2) which indicates the net warming and cooling effects, respectively. The highest RF at SFC was in the month of April (-30Wm(-2)) which is coincident with the highest BC mass level. The BC atmospheric radiative forcing (ARF) was +30.16 (annual mean) Wm(-2) varying from +23.1 to +43.8Wm(-2). The annual mean atmospheric heating rate (AHR) due to the BC aerosols was 0.86Kday(-1) indicates the enhancement in radiation effect over the study region. The Weather Research and Forecasting model

    As part of an optical spectroscopic survey of nearby, bright galaxies, we have identified a sample of over 200 emission-line nuclei having optical spectra resembling those of giant extragalactic H II regions. Such "H II nuclei," powered by young, massive stars, are found in a substantial fraction of nearby galaxies, especially those of late Hubble type. This paper summarizes the observational characteristics of H II nuclei, contrasts the variation of their properties with Hubble type, and compares the nuclear H II regions with those found in galaxy disks. Similarities and differences between H II nuclei and luminous starburst nuclei are additionally noted.

    The photosynthetic reaction center (RC) from the Rhodobacter sphaeroides bacterium has been covalently bioconjugated with a NIR-emitting fluorophore (AE800) whose synthesis was specifically tailored to act as artificial antenna harvesting light in the entire visible region. AE800 has a broad absorption spectrum with peaks centered in the absorption gaps of the RC and its emission overlaps the most intense RC absorption bands, ensuring a consistent increase of the protein optical cross section. The covalent hybrid AE800-RC is stable and fully functional. The energy collected by the artificial antenna is transferred to the protein via FRET mechanism, and the hybrid system outperforms by a noteworthy 30% the overall photochemical activity of the native protein under the entire range of visible light. This improvement in the optical characteristic of the photoenzyme demonstrates the effectiveness of the bioconjugation approach as a suitable route to new biohybrid materials for energy conversion, photocatalysis, and biosensing.

    We present near-infrared H-, K-, L- and M-band photometry of the Galactic Center from images obtained at the ESO VLT in May and August 2002, using the NAOS/CONICA (H and K) and the ISAAC (L and M) instruments. The large field of view (70" x 70") of the ISAAC instrument and the large number of sources identified (L-M data for 541 sources) allows us to investigate colors, infrared excesses and extended dust emission. Our new L-band magnitude calibration reveals an offset to the traditionally used calibrations, which we attribute to the use of the variable star IRS7 as a flux calibrator. Together with new results on the extinction towards the Galactic Center (Scoville et al. 2003; Raab 2000), our magnitude calibration results in stellar color properties expected from standard stars and removes any necessity to modify the K-band extinction. The large number of sources for which we have obtained L-M colors allows us to measure the M-band extinction to A_M=(0.056+-0.006)A_V (approximately =A_L), a considerably high...

    The objective of the present study was to determine the main lines of the development of a regional cochlear implantation centre and to estimate the effectiveness of rehabilitation of the children treated with the use of cochlear implantation. Analysis of the results of the work of the branch of the Russian Research and Practical Centre of Audiology and Hearing Rehabilitation based at Voronezh Regional Children's Clinical Hospital No 1 provided materials for the establishment of the principle directions of activities of the regional cochlear implantation centre where a total of 161 children have been kept under observation during the last years. Fifty six of the 138 children at the age varying from 1 to 12 years were given the surgical treatment. The patients were followed up within two and more years after connection of the speech processor. The study group was comprised only of the pre-lingually deaf children. It is concluded that the performance of most cochlear implantation procedures based at local centres allows to reduce the cost of rehabilitation and makes the high-tech medical aid more readily available to the patients; moreover, the practical introduction of remote speech processor programming software into the work of regional cochlear implantation centres enhances the effectiveness of the rehabilitative measures based at local medical facilities.

    The Regional Training Center (RTC) was established at the OB/GYN Hospital, Ain Shams University, to overcome the shortage of trained service providers in the Egyptian family planning program. Over the past three years, RTC has successfully met the training needs for family planning services in Egypt. As part of the RTC's efforts, nine Satellite Training Centers (STCs) were established to provide quality training for service providers in nine governorates in Egypt. The RTC role in family planning activities is described. A study was conducted to test different teams in the implementation of the RTC follow-up system in three governorates in upper Egypt. The study was a cost-effectiveness analysis designed to determine which team best implements the follow-up system, with the ultimate goal of providing policymakers and program administrators with a better understanding of the role of the follow-up of trainees in providing high quality family planning services. The study was conducted during May-December 1991 using a sample of three STCs. The study produced valuable information for improving training logistics, clinical training, use of audiovisual equipment, record keeping, and overcoming training problems at STCs. The information clearly showed the importance of the follow-up system in providing administrators and decisionmakers with information needed to assess the operations and performance of STCs. Furthermore, the strengths and weaknesses of training at the STCs were revealed, giving useful insights for quality improvement. The use of RTC staff is the most cost-effective approach to follow-up at the STCs. PMID:12179785

    The energy crisis of 1973 prompted the Federal Government and private industry to look into alternative methods to save energy. At the same time the constant reduction of operations and maintenance funds during the last 5 years forced Glenn Research Center (GRC) to look for alternative funding sources to meet the mandate to reduce energy consumption. The Super Energy Savings Performance Contract (ESPC) was chosen as a viable source of facility improvement funding that can create larger project scope and help replace aging, inefficient equipment. This paper describes Glenn's participation in the Department of Energy (DOE) Super ESPC program. This program provided Glenn cost savings in the performance of energy audits, preparation of documents, evaluation of proposals, and selection of energy service company (ESCO).

    Changing climate and hydro-meteorological boundary conditions are among the most severe challenges to Africa in the 21st century. In particular West Africa faces an urgent need to develop effective adaptation and mitigation strategies to cope with negative impacts on humans and environment due to climate change, increased hydro-meteorological variability and land use changes. To help meet these challenges, the German Federal Ministry of Education and Research (BMBF) started an initiative with institutions in Germany and West African countries to establish together a West African Science Service Center on Climate Change and Adapted Land Use (WASCAL). This activity is accompanied by an establishment of trans-boundary observation networks, an interdisciplinary core research program and graduate research programs on climate change and related issues for strengthening the analytical capabilities of the Science Service Center. A key research activity of the WASCAL Competence Center is the provision of regional climate simulations in a fine spatio-temporal resolution for the core research sites of WASCAL for the present and the near future. The climate information is needed for subsequent local climate impact studies in agriculture, water resources and further socio-economic sectors. The simulation experiments are performed using regional climate models such as COSMO-CLM, RegCM and WRF and statistical techniques for a further refinement of the projections. The core research sites of WASCAL are located in the Sudanian Savannah belt in Northern Ghana, Southern Burkina Faso and Northern Benin. The climate in this region is semi-arid with six rainy months. Due to the strong population growth in West Africa, many areas of the Sudanian Savannah have been already converted to farmland since the majority of the people are living directly or indirectly from the income produced in agriculture. The simulation experiments of the Competence Center and the Core Research Program are

  10. Larger Centers Produce Better Outcomes in Pediatric Cardiac Surgery: Regionalization is a Superior Model - The Con Prospective.

    Science.gov (United States)

    Danton, Mark H D

    2016-01-01

    Regionalization, in the context of congenital heart surgery, describes a process where smaller units close and patients are redistributed to larger centers. Proponents argue this will produce superior patient outcome based primarily on a volume-outcome effect. The potential disadvantage is that, as distance to center increases, access to service is compromised. In this article the volume-outcome effect is appraised and the effect of risk-stratification and threshold volumes explored. Access to service, and how certain congenital lesions and demographics might be disadvantaged, is reviewed. Alternative models are considered including collaborative programing and a standardizing approach of agreed parameters in personnel and infrastructure. Finally the influence of newer developments and quality metrics, including outcome databases, digital technologies and team-cognitive performance, needs to be factored in as the future unfolds. Ultimately, the design of a national congenital cardiac program should aspire to deliver care that is optimal, equitable and economic for the whole population. The solution lies in the distillation of competing variables cognizant of regional demographics and geography. PMID:27060038

    Ionizing radiation is a safe and effective method for eliminating bacterial pathogens from food products and disinfestation of fruits and vegetables. Since 1980 research has been conducted at USDA's Eastern Regional Research Center pertaining to the elimination of food-borne pathogens from meat, poultry, fruit and vegetable products. Recent work has focused on elimination of pathogens such as Escherichia coli O157:H7, Salmonella spp., and Listeria monocytogenes from ready-to-eat (RTE) food products including hot dogs, bologna, lettuce, cilantro, sprouts and seeds, and frozen vegetables. The ionizing radiation dose required to eliminate those pathogens from RTE foods has been found to be commodity, formulation and temperature dependent. The need to eliminate bacterial pathogens from RTE food products must always be balanced with the maintenance of product quality. In addition to determining the effective ionizing radiation doses required for pathogen elimination the effects of irradiation on product chemistry, nutritional value and organoleptic quality have also been determined. A review of the studies conducted at USDA's Eastern Regional Research Center in 2002 and 2003 is presented in this article.

    We present 74 MHz radio continuum observations of the Galactic center region. These measurements show nonthermal radio emission arising from molecular clouds that is unaffected by free-free absorption along the line of sight. We focus on one cloud, G0.13--0.13, representative of the population of molecular clouds that are spatially correlated with steep spectrum (alpha^{74MHz}_{327MHz}=1.3\\pm0.3) nonthermal emission from the Galactic center region. This cloud lies adjacent to the nonthermal radio filaments of the Arc near l~0.2^0 and is a strong source of 74 MHz continuum, SiO (2-1) and FeI Kalpha 6.4 keV line emission. This three-way correlation provides the most compelling evidence yet that relativistic electrons, here traced by 74 MHz emission, are physically associated with the G0.13--0.13 molecular cloud and that low energy cosmic ray electrons are responsible for the FeI Kalpha line emission. The high cosmic ray ionization rate ~10-13 s-1 H-1 is responsible for heating the molecular gas to high temperat...

    We estimated absolute shifts of Fe I and Fe II lines from Fourier-transform spectra observed in solar active regions. Weak Fe I lines and all Fe II lines tend to be red-shifted as compared to their positions in quiet areas, while strong Fe I lines, whose cores are formed above the level $\\log \\tau_5\\approx-3$ (about 425 km), are relatively blue-shifted, the shift growing with decreasing lower excitation potential. We interpret the results through two-dimensional MHD models, which adequately reproduce red shifts of the lines formed deep in the photosphere. Blue shifts of the lines formed in higher layer do not gain substance from the models.

    Full Text Available Introduction: Hypertension (HTN is a common health problem in Saudi Arabia. Good control depends on the quality of care, which should be supervised and monitored regularly through clinical audit. Aims: The objective of this study was to assess the quality of HTN care at Al-Manhal Family Practice, Aseer Region, Saudi Arabia. Settings and Design: This study was conductedin 2009 at Al-Manhal Family Practice, Aseer Region, Saudi Arabia. Materials and Methods: Medical records of all hypertensive patients were extracted and reviewed using master sheets. Assessment of processes and outcomes of HTN care were based on the standards of quality assurance manual issuedby the Ministry of Health. Statistical Analysis Used: Data were entered and analyzed by SPPS, version 15. Relevant statistical tests were used accordingly and the P-value was considered significant when it was less than 0.05. Results: A total of 295 medical records were reviewed and assessed. Most patients were Saudi, married, and about 50% were educated. Two-hundred and thirty-one records were assessed for processes and outcomes of HTN care. Weight measurement and physical examination were carried out for 99% and 97% of the patients, respectively. For 53% of the patients, blood was checked for glucose and kidney function and a lipid profile was done. More than two-thirds of the patients were overweight and obese while 46% had diabetes. Less than one half of the patients had good control of HTN. Conclusions: By most standards, quality of HTN care in Al-Manhal Family Practice was unsatisfactory. Most of the patients had comorbidities and poor HTN control. Essential facilities should be provided to the practice to optimize HTN care and to improve the degree of control.

    The Cs-137 contamination of the Bryansk Region occurred in the period from April 27 to May 10 into several stages. The complicated character of the soil radionuclide contamination on the Bryansk Region is caused by different nature of the radioactive fallout: dry and wet. Thus, in a number of cases Cs-137 soil pollution is directly connected with the rain intensity, which is well known, have multifractal nature. In some parts of contaminated territory the overlay of different types of fallout was observed. The radioactive contamination of the landscape is a result from nonlinear interplay of geophysical factors which intervene over a large range of scale. As a result of the fallout Cs-137 pattern can be described as a multifractal. Consequently, fields of contamination observed have an extreme spatial variability, frequently cited "hot spots" or "leopard's skin. As an estimate of background radiation levels, we relied on a dataset of air-gamma-survey of the Bryansk Region, carried out by SSC AEROGEOFIZIKA in the summer of 1993. This dataset includes geo-positioned data of Cs-137 deposition in a grid of 100x100 m with values range from 3 to 11*104 kBq/m2. Airborne gamma survey gave the smoothed values of the Cs-137 density of contamination in comparison with the data, obtained directly as a result of soil sampling. However, even in this case in the east part of the Bryansk test site we can observed the"hot spots" (by size several hundred meters) as natural phenomenon. The article presents the results of the geostatistical and multifractal analysis of the Cs-137 contamination. Scaling analysis was conducted to investigate the linkages between the spatial variability of soil Cs-137 contamination and some landscape characteristics.

    Abstract The objectives of this study were to assess linkage disequilibrium (LD) and selection-induced changes in single nucleotide polymorphism (SNP) frequency, and to perform association mapping in popcorn chromosome regions containing quantitative trait loci (QTLs) for quality traits. Seven tropical and two temperate popcorn populations were genotyped for 96 SNPs chosen in chromosome regions containing QTLs for quality traits. The populations were phenotyped for expansion volume, 100-kernel weight, kernel sphericity, and kernel density. The LD statistics were the difference between the observed and expected haplotype frequencies (D), the proportion of D relative to the expected maximum value in the population, and the square of the correlation between the values of alleles at two loci. Association mapping was based on least squares and Bayesian approaches. In the tropical populations, D-values greater than 0.10 were observed for SNPs separated by 100-150 Mb, while most of the D-values in the temperate populations were less than 0.05. Selection for expansion volume indirectly led to increase in LD values, population differentiation, and significant changes in SNP frequency. Some associations were observed for expansion volume and the other quality traits. The candidate genes are involved with starch, storage protein, lipid, and cell wall polysaccharides synthesis.

    Severe hot weather in summer season becomes a big social problem in metropolitan areas, including the Nagoya region in Japan. Surface air temperature warming is projected in the future. Therefore, the reduction of surface air temperature is an urgent issue in the urban area. Although there are several studies dealing with the effects of global climate change and urbanization to the local climate in the future, these studies tend to ignore the future population changes. This study estimates future land-use scenarios associated with the multi-projections of future population and investigates the impacts of these scenarios on the surface temperature change. The Weather Research and Forecast model ver. 3.3.1 (hereafter, WRF) was used in this study. The horizontal resolutions were 20km, 4km, and 2km, for outer, middle, and inner domains, respectively. The results from the inner domain, covering the Nagoya region, were used for the analysis. The Noah land surface model and the single-layer urban canopy model were applied to calculate the land surface processes and urban surface processes, respectively. The initial and boundary conditions were given from the NCEP/NCAR reanalysis data in August 2010. The urban area ratio used in the WRF model was calculated from the future land-use data provided by the S8 project. The land-use data was created as follows. (1) Three scenarios of population, namely, with high-fertility assumption and low-mortality assumption (POP-high), with medium-fertility assumption and medium-mortality assumption (POP-med), and with low-fertility assumption and high-mortality assumption (POP-low), are estimated using the method proposed by Ariga and Matsuhashi (2012). These scenarios are based on the future projections provided by the National Institute of Population and Social Security Research. (2) The future changes in urban area ratio were assumed to be proportional to the population change (Hanasaki et al., 2012). The averaged urban area ratio in

    Radioactivity concentrations of 226Ra, 238U, 232Th, 40K and 137Cs in soil samples around the research reactor in Tajoura region, north Libya, and the surroundings have been measured using gamma spectrometry. The primary aim of the study was to establish baseline radioactivity levels in the environs of the research reactor. The mean activity concentrations of 226Ra, 238U, 232Th, 40K and 137Cs were found to be 36.05, 14.51, 10.19, 232.5 and 1.03 Bq/kg , respectively. The mean activity concentrations of 226Ra were obtained which help to evaluate the radiation hazard indices as radium equivalent and external hazard indices. In addition, to assess the radiation risk to a bio system, the absorbed dose rate and the annual effective dose rate were also evaluated. The observed values were lower than the recommended limits.

    Loss of heterozygosity (LOH) has been reported to cause false human leukocyte antigen (HLA) homozygous typing results in pre-transplant patients suffering from haematological malignancies, who in fact are HLA heterozygous. This poses a challenge for histocompatibility testing, as a stem cell graft from a genuinely HLA homozygous donor to a mistyped patient may lead to acute life-threatening graft-vs-host disease. LOH in the HLA region on chromosome 6 is known to be quite common in solid tumours, helping malignant cells to escape T-cell surveillance, but the incidence in haematological malignancies is less well known and the estimates vary. Here we report LOH in the HLA region of five patients with haematological malignancy. We found considerable differences in sensitivity between the three different HLA typing methods used in our laboratory: SSP was clearly the most sensitive method for detecting the lost haplotype, followed by rSSO, while SBT was the least sensitive technique. A subsequent, retrospective genotyping of 65 HLA homozygous haematological patients by SSP method showed no mistyped LOH cases in our laboratory in the past 10 years. The frequency of HLA homozygosity was found to be similar between haematological patients and control groups. It is important for an HLA laboratory to be aware of the differences in various HLA typing techniques' sensitivity for detecting an under-represented haplotype between HLA typing techniques when genotyping patients with haematological diseases. It is advisable for HLA laboratories to have at least two different methods with different sensitivities in their repertoire to be able to retype samples when a false homozygous result is suspected.

    The detection of gamma-rays from the source HESS J1745-290 in the Galactic Center (GC) region with the H.E.S.S. array of Cherenkov telescopes in 2004 is presented. After subtraction of the diffuse gamma-ray emission from the GC ridge, the source is compatible with a point-source with spatial extent less than 1.2'(stat.) (95% CL). The measured energy spectrum above 160 GeV is compatible with a power-law with photon index of 2.25 +/- 0.04(stat.) +/- 0.10 (syst.) and no significant flux variation is detected. These measurements are discussed in the framework of dark matter annihilation. It is found that the bulk of the VHE emission must have non-dark-matter origin. Loose constraints on the velocity-weighted annihilation cross section are derived assuming the presence of an astrophysical non-dark-matter gamma-ray contribution.

    Full Text Available Background: Call handlers employed in call centers repeatedly undergo stress in their day-to-day lives and this can have deleterious effects on their health. Objectives: The objectives were to study the levels of stress, anxiety, and depression, and their predictors among call handlers employed in international call centers in the National Capital Region (NCR of Delhi. Materials and Methods: A cross-sectional questionnaire-based survey was conducted among 375 call handlers aged 18-39 years. Depression Anxiety Stress Scale- 42 (DASS-42 was used to measure stress, anxiety, and depression along with a pretested sociodemographic questionnaire. Univariate analysis was done to find out the association of stress, anxiety, and depression with various factors. Variables with P < 0.25 were included in multiple logistic regression and three models were developed each for stress, anxiety, and depression. Results: The prevalence of stress, anxiety, and depression among call handlers was 46.7%, 57.1%, and 62.9% respectively. Abnormal sleep quality, prolonged travel time, and lack of relaxation facilities at the office were predictors of stress and depression. The presence of physical ailments, the absence of hobbies, temporary/part-time employment, and traveling long-distance to office were significant predictors of anxiety among call handlers. Conclusion: Call handlers face a high burden of stress, anxiety, and depression. Public health specialists need to pay adequate attention to their health problems.

    We aim to understand the contribution of the ionized, atomic and molecular phases of the ISM to the [CII] emission from clouds near the dynamical center and the BCLMP302 HII region in the north of the nearby galaxy M33 at a spatial resolution of 50pc. We combine high resolution [CII] spectra taken with the HIFI spectrometer onboard the Herschel satellite with [CII] Herschel-PACS maps and ground-based observations of CO(2-1) and HI. All data are at a common spatial resolution of 50pc. Typically, the [CII] lines have widths intermediate between the narrower CO(2-1) and broader HI line profiles. We decomposed the [CII] spectra in terms of contribution from molecular and atomic gas detected in CO(2-1) and HI, respectively. We find that the relative contribution of molecular and atomic gas traced by CO(2-1) and HI varies depends mostly on the local physical conditions and geometry. We estimate that 11-60% and 5-34% of the [CII] intensities in the center and in BCLMP302, respectively, arise at velocities showing no...

  11. Changes in Hydrologic Conditions and Greenhouse Gas Emissions in Circumpolar Regions due to Climate Change Induced Permafrost Retreat

    International Nuclear Information System (INIS)

    Thawing permafrost peatlands substantially influence Canadian northern ecosystems by changing the regional hydrology and mobilizing the vast carbon (C) reserves that results in increased greenhouse gas (GHGs) emissions to the atmosphere. With permafrost distribution controlled largely by topography and climate, our International polar y ear (IPY) study intensively monitored the local C cycling processes and GHG fluxes associated with different hydrologic and permafrost environments at 4 sites along a climatic gradient extending from the Isolated patches permafrost Zone (northern alberta), to the continuous permafrost Zone (Inuvik, NWT). Each site encompasses a local gradient from upland forest and peat plateau to collapse scar. Our multi-year measurements of peatland profiles and flux chambers for CH4 and CO2 concentrations and stable isotope ratios indicate processes, including methanogenesis, methanotrophy, transport and emission that control the distribution of these GHGs. These relationships are modulated by fluctuating local soil water and corresponding ecosystem conditions. The gas geochemistry shows that significant surface CH4 production occurs by both hydrogenotrophic and acetoclastic methanogenesis in submerged, anaerobic peats, e.g., collapse scars, whereas methane oxidation is restricted to aerobic, drier environments, e.g., upland sites and peat-atmosphere interface. The most active methanogenesis and emissions are in areas of actively thawing permafrost contrasting with sites under continuous permafrost. This degree of methanogenesis is being amplified by the increased rate of Arctic warming and the rapid retreat of permafrost in canada's arctic (approximately. 2.5 km/a). (author)

    In the present work, indoor radon and thoron measurements have been carried out from different locations of Jodhpur and Nagaur districts of Northern Rajasthan, India using RAD7, a solid state alpha detector. The radon and thoron concentration in indoor air varies from 8.75 to 61.25 Bq m{sup −3} and 32.7 to 147.2 Bq m{sup −3} with the mean value of 32 and 73 Bq m{sup −3} respectively. The observed indoor radon concentration values are well below the action level recommended by International Commission on Radiological Protection (200-300 Bq m{sup −3}) and Environmental Protection Agency (148 Bq m{sup −3}). The survey reveals that the thoron concentration values in the indoor air are well within the International Commission on Radiological Protection (2005). The calculated total annual effective dose due to radon level in indoor air varies from 0.22 to 1.54 mSv y{sup −1} with the mean value of 0.81 mSv y{sup −1} which is less than even the lower limit of action level 3-10 mSv y{sup −1} recommended by International Commission on Radiological Protection (2005)

    This study was carried out for estimating the seawater intrusion at the disturbed aquifer by a large scale construction when building a power plant in a coastal region, located in southeastern part of the Korean peninsula. Groundwater sampling and vertical profiling of electrical conductivity(EC) for 8 monitoring wells were carried. EC profiling results shows that maximum EC for PW-5, 6 and 7 is over 40 mS/cm, for PZ-1, 3, 4 and 8 is 18.76, 4.46, 26.16, 21.42 mS/cm and for PZ-2 is 0.79 mS/cm,respectively. Chemical composition of water samples shows that water types of Na-Cl for PZ-5, 6, and 7 (excavated and backfilled area), Na-Cl-SO4 for PZ-4 and PZ-8, Na-Ca-Mg-Cl for PZ-1, Ca-Na-SO4-Cl for PZ-2, and Mg-Ca-Na-SO4 for PZ-3. In addition, the bivariate plot of SO4/Cl(meq ratios) and SO4(mmol/L) indicates that PZ-4, 5, 6, 7 and 8 appear to be seawater, PZ-1 is located at mixing zone between freshwater and seawater, and PZ-2 is freshwater. However, based on the high SO42- level and (HCO3-/Sum anions} ratio less than 0.8, groundwater at PZ-3 seems to show the gypsum dissolution. The gypsum dissolution was attributed to the effect of sea-water intrusion on ageing of lean concrete that was used for backfill around the PZ-3. Key words : large scale construction, EC profiling, hydrochemistry, sea-water intrusion, concrete ageing Acknowledgement This study has been carried out under the Nuclear R&D Program [No. 2010-0001070] supported by the Ministry of Education, Science and Technology, Republic of Korea.

    We present the first survey results of hard X-ray point sources in the Galactic Center (GC) region by NuSTAR. We have discovered 70 hard (3-79 keV) X-ray point sources in a 0.6 deg^2 region around Sgr A* with a total exposure of 1.7 Ms, and 7 sources in the Sgr B2 field with 300 ks. We identify clear Chandra counterparts for 58 NuSTAR sources and assign candidate counterparts for the remaining 19. The NuSTAR survey reaches X-ray luminosities of ~4 x and ~8 x 10^32 erg s^-1 at the GC (8 kpc) in the 3-10 and 10-40 keV bands, respectively. The source list includes three persistent luminous X-ray binaries and the likely run-away pulsar called the Cannonball. New source-detection significance maps reveal a cluster of hard (>10 keV) X-ray sources near the Sgr A diffuse complex with no clear soft X-ray counterparts. The severe extinction observed in the Chandra spectra indicates that all the NuSTAR sources are in the central bulge or are of extragalactic origin.

    Poor performance of sit-to-stand (STS) has been identified as one of the predictors of fall risk among elderly adults. This study examined differences in the whole body center of mass (COM) kinematic variables in relation to the regions of stability between elderly adults with difficulty in STS and healthy individuals. Whole body motion data while performing STS were collected from 10 young, 10 elderly and 10 elderly subjects with difficulty in STS. Young subjects were also asked to stand up with their trunk purposely bent forward. The regions of stability were defined with COM position at seat-off and its instantaneous velocity (ROSv) or peak acceleration (ROSa), using a single-link-plus-foot inverted pendulum model. Peak COM accelerations prior to seat-off differed significantly among groups; however, no significant differences were detected in its velocities at seat-off. The ROSa demonstrated a better ability to discriminate elderly adults with difficulty from healthy individuals. Although a similar COM momentum was observed at seat-off, how the momentum was controlled differed between healthy individuals and individuals with difficulty in STS. ROSa could provide insight into how the COM momentum is controlled prior to seat-off, which could be used to differentiate individuals with functional limitations from healthy individuals.

    OBJECTIVE: To compare the incidence of tuberculosis due to Mycobacterium bovis in humans to the prevalence of M. bovis infection in cattle in south-west Ireland and discuss possible links between them. SETTING: In the south-west region of Ireland, a mixed urban and rural community (pop. 536,000), there is a residuum of human tuberculosis caused by M. bovis. METHODS: A retrospective analysis of the incidence of culture-positive M. bovis disease in humans in south-west Ireland from 1983 to 1994 and of the results of tuberculin testing in cattle from 1978 to 1994 for the same region. RESULTS: One to five cases of human tuberculosis due to M. bovis were recorded per year while the overall prevalence of bovine infection fell gradually during the period of study from 467 tuberculin-positive animals per 100,000 cattle tested in 1983 to 158 per 100,000 in 1994. CONCLUSION: The low incidence plateau of human tuberculosis due to M. bovis together with the decline in prevalence of animal infection in the overall period studied suggest a cut-off in the animal to human chain of infection at two points; the animal source and the ingestion of (now pasteurized) milk. This would suggest that disease in humans is now due to reactivation of previous foci of infection which were acquired when milk pasteurization was not compulsory. Based on this, we would anticipate a further reduction and possible elimination of human tuberculosis due to M. bovis in this region in the next 10-15 years.

    Deep lower crustal intraplate earthquakes are infrequent and the mechanism of their occurrence is not well understood. The Narmada–Son-lineament region in central India has experienced two such events, the 1938 Satpura earthquake and the 1997 Jabalpur earthquake, having a focal depth of more than 35 km. We have estimated elastic stresses due to the crustal density and mechanical properties heterogeneities along the Hirapur–Mandla profile passing through the Jabalpur earthquake region to analyse conditions suitable for the concentration of shear stresses in the hypocentral region of this earthquake. Elastic stresses have been computed by a finite element method for a range of material parameters. The results indicate that the shear stresses generated by the density heterogeneities alone are not able to locally enhance the stress concentration in the hypocentral region. The role of mechanical properties of various crustal layers is important in achieving this localization of stresses. Among a range of material parameters analysed, the model with a mechanically strong lower crust overlying a relatively weak sub-Moho layer is able to enhance the stress concentration in the hypocentral region, implying a weaker mantle in comparison to the lower crust for this region of central India.

    Full Text Available BACKGROUND : Incidence of rectal cancer has wide geographical variation. Disease pattern in developing countries is different from developed countries as majority of the patients present in advanced stage because of delayed referral and lack of uniform treatment practices. AIMS : Present study describes the patient profile and treatment results from a tertiary care cancer center in India. SETTING AND DESIGN : Tertiary care Regional cancer center. Retrospective analysis 89 patients with rectal adenocarcinoma treated between 1995 and 2002 were analyzed. METHODS: Patients with adenocarcinoma rectum were evaluated in a G.I. Oncology clinic and were treated using multimodality protocols involving surgery, radiotherapy and adjuvant chemotherapy. STATISTICAL ANALYSIS : A descriptive analysis of patient and disease profile,treatment patterns and out come was performed. Survival analysis was performed using Kaplan-Meier method. RESULTS : Mean age of the patients was 45.4 years and majority of them had tumor in lower third of rectum with evidence of extrarectal spread. Seventy five percent of the patients underwent curative resection with abdominoperineal resection being the commonest procedure. Forty seven percent of patients were given short course preoperative radiotherapy and the remaining received postoperative radiotherapy. Sixty four percent of patients could complete planned adjuvant chemotherapy. Operative mortality was 2% and 23% had morbidity. Local recurrence rate was 8.9%. 5-year disease free and overall survival was 54% and 58% respectively. CONCLUSION : Majority of rectal cancer patients present with locally advanced and low rectal growths leading to low sphincter salvage rates. Despite the advanced stage of presentation optimal oncologic results can be obtained by using a good surgical techniques in combination with adjuvant radiotherapy and chemotherapy. Short course preoperative radiotherapy seems to be more feasible in Indian context

    Full Text Available In China's healthcare reform, community health centers (CHCs are designed to take a pivotal role in providing primary care. Whilst about 20% of all outpatient care in China is delivered by the traditional Chinese medicine (TCM sector, hospitals, instead of CHCs, are major providers. Using current patterns of patient utilization this study aims to inform CHCs on how they may strengthen access to TCM services. Three thousand three hundred and sixty CHC patients from six cities within the urban Pearl Delta Region were enumerated using multistage cluster sampling. Fifty-two percent had visited herbalists within three months with a mean visit frequency of 1.50 times. Herbal treatments, which are cheaper than western medicines, were more popular amongst those who needed to pay out of pocket including the uninsured. Herbal medicines appeared to be an alternative for those who are underinsured. Acupuncturists and massage therapists were visited by smaller proportions, 6.58% and 5.98%, respectively, with a mean three-month visit of 0.27 and 0.26 times. Access was restricted by lack of social insurance coverage. Whilst increasing provision of TCM in CHCs might respond to patient demand, increasing insurance coverage for TCM needs to be evaluated using current evidence on safety and effectiveness.

    Comparing with the light water reactor, sodium as a reactor coolant violently reacts with oxygen in the containment atmosphere. Due to this chemical reaction, heat generated from the combustion heat increases the temperature and pressure in the containment atmosphere. The structural integrity of the containment building which is a final radiological defense barrier is threaten. A sodium fire event in the containment due to air ingress into the cover gas region in the reactor vessel is classified as one of the design basis events in the PGSFR. This event comes from a leak or crack on the reactor upper closure header surface. It accompanys an event of the radiological fission products release to the inside the containment. In this paper, evaluation for the sodium fire and radiological influence due to air ingress into the cover gas region of the reactor vessel is described. To evaluate this event, the CONTAIN-LMR, MACCS-II and OR-IGEN-II codes are used. For the sodium pool fire event in the containment, the performance evaluation and radiological influence are carried out. In the thermal hydraulic aspects, the 1 cell containment yields the most conservative result. In this event, the maximum temperature and pressure in the containment are calculated 0.185 MPa, 280.0 .deg. C, respectively. The radiological dose at the EAB and LPZ are below the acceptance criteria specified in the 10CFR100.

    Ear infection linked with frequent antibiotic prescription, hearing impairment, severe disability and death is a public health threat in developing countries. However, there is scarcity of documented data in the study area. Therefore, this study aimed at determining bacterial etiologic agents and their antimicrobial susceptibility patterns among patients of all age groups referred to Bahir Dar Regional Health Research Laboratory Center. Retrospective data recorded on culture and antimicrobial susceptibility profile were retrieved for analysis. Pus swabs from discharging ears collected and processed for aerobic bacteria culture and susceptibility testing. Of the total 368 pus swab samples processed, 296 (80.4 %) were culture positive. Of which, 289 (97.6 %) were bacteria and 7 (2.4 %) were yeast cells. The proportion of ear infection was higher in males (92.7 %) than females (65 %) (P = 0.014). The frequency of ear infection below 21 years of age was 65.2 %. The predominant isolate was Pseudomonas aeruginosa (29.7 %) followed by Staphylococcus aureus (26.3 %) and Proteus spp. (21.9 %). High level of antimicrobial resistance rates were observed for amoxicillin/clavulanic acid, ampicillin and penicillin whereas ciprofloxacin, ceftriaxone, chloramphenicol, cotrimoxazole, gentamicin and amikacin were found effective against the isolated bacteria. Aerobic bacterial otitis media linked with high levels of resistance against amoxicillin/clavulanic acid and ampicillin is major health problem in the study area. Moreover, considerable level of oxacillin resistant S. aureus suggests the diffusion of methicillin resistant S. aureus in the community. Therefore, treatment of otitis media in the study area needs to be guided by antibiotic susceptibility testing of isolates. PMID:27119070

  15. Assurance of risk assessment and protection distant transportation and fall out of pollutants under large anthropogenic on nuclear power stations due to mountainous regional peculiarities

    International Nuclear Information System (INIS)

    Full text: All types of industrial activities require the norms of protection, assessment of corresponding risks to preserve the pollution and degradation of corresponding areas. To make available the sustainable development of the country the risk assessment of possible accidents on the big enterprises is foreseen that provides preparedness of the country and possibility of the prevention measures and mitigation of the accidents. While big anthropogenic accidents in mountainous countries - the main paths for transportation of the pollution are the rivers and sea basins. Due to overpopulation of these areas assessment of the pollution risks are very important. Problem of forecast and distant atmospheric transportation of the toxic products and corresponding risk assessment under anthropogenic damages is multi-component and depends on meteorological conditions and frontier layer of atmosphere. Generally, for real relief and basic fields the problem is not solved yet especially taking into consideration the big level and shortest time of the process being of the natural anthropogenic accidents in mountainous regions. Usually, geostropic drawing for determined relief is used. Integral differential equations taking into consideration a physical- chemical characteristic of the pollutants, their transformations, fall out, coagulations, washing out and self rectification in general cannot be solved. In last time essential success in formalization of above-mentioned equations i.e. carrying out some simplifications give possibility to establish necessary modeling on the basis of numerical calculations. In the most general case forecasting model is essentially limited because of bulky size of accounting schemes and necessity of powerful and high-speed computers. Main ways of achievement of further success is connected with so called 'seasonal typification' with applied a priory calculation of probabilistic picture of the pollutants concentration fields, as well as

  17. A mechanical model of stereocilia that demonstrates a shift in the high-sensitivity region due to the interplay of a negative stiffness and an adaptation mechanism

    International Nuclear Information System (INIS)

    Stereocilia are the basic sensory units of nature's inertial sensors and are highly sensitive over broad dynamic ranges, which is a major challenge in the design of conventional engineering sensors. The high sensitivity that is maintained by stereocilia was hypothesized to exist due to a combination of adaptation and negative stiffness mechanisms, which shift the region of highest sensitivity toward the active operation range of the stereocilia bundle. To examine the adaptation hypothesis in terms of its potential applicability to future applications regarding the design of inertial sensors, we developed a mechanical mimicry of the interplay between negative stiffness and the adaptation of the stereocilia that produces spontaneous oscillation of the hair bundle. The mechanical model consists of an inverted pendulum and a fixed T-bar that mimic the interaction of two adjacent stereocilia. To focus on the interaction of one gating spring and the corresponding adaptation motor without the effect of coupling from the other gating springs attached to the neighboring stereocilia, we fixed one bar that contains the adaptation motor. To emulate the negative resistance of the tip-link due to the transient stiffness softening by the gating ion channel, a magnet pair was attached to the top of the inverted pendulum and the fixed T-bar. Readjustment of the tip-link tension by the ‘slipping down and climbing up’ motion of the adaptation molecular motors was demonstrated by the side-to-side movement of the magnet by a step motor. The negative stiffness region was observed near the equilibrium position and shifted with the activation of the adaptation motor. The temporal demonstration of the stiffness shift was measured as a spontaneous oscillation. The results showed that the interplay between the negative stiffness and the adaptation mechanism was mechanically produced by the combination of a repulsive force and its continuous readjustment and is better understood through a

    A severe accident at the Chernobyl NPP on April 26th, 1986 has led to radioactive contamination of many regions of the former USSR, now belonging to the Ukraine, the Republic of Belarus and the Russian Federation. Both natural and arable ecosystems have been subjected to fallout of radioactive isotopes. However both the distribution of radionuclides that define radioecological situation has depended not only on the initial contamination density but also on the landscape geochemical features of the areas controlling biogenic and abiogenic factors of radionuclide migration. To study and monitor peculiarities of migration of the most radioecologically significant radionuclides of Cs-137 and Sr-90 in different natural landscapes the Russian Scientific and Practical Experimental Center of the former State Chernobyl Committee has organized in 1992 a network of experimental plots in the most contaminated western part of the Bryansk region. It included 19 plots 100 m x 100 m in size which characterized 8 meadow and 11 forested catenas in the basin of the Iput' river. Cs-137 contamination level of the plots varied in 1992 from 740 kBq/m2 to 1850 kBq/m2. Although the study site has been located in the remote zone and the contamination was of condensation type the sampling performed at 11 plots registered some refractory radionuclides (144Ce, 154Eu, 238,239,240Pu and 90Sr) that proved the presence of fuel particles in fallout as far as 200 km from the damaged reactors. The sampling and monitoring scheme was organized to determine: the isotopic composition and contamination density of the plots; 2) estimation of radionuclide vertical and lateral migration; 3) evaluation of radionuclide inventories in different soil horizons; 4) calculation of radionuclide transfer in soil-plant system. Radiation measurements included field gamma-spectrometry using collimated gamma spectrometer "Corad" developed in the Kurchatov Institute and laboratory spectrometry the soil and plant samples

    Predictions of twenty-first century sea level change show strong regional variation. Regional sea level change observed by satellite altimetry since 1993 is also not spatially homogenous. By comparison with historical and pre-industrial control simulations using the atmosphere-ocean general circulation models (AOGCMs) of the CMIP5 project, we conclude that the observed pattern is generally dominated by unforced (internal generated) variability, although some regions, especially in the Southern Ocean, may already show an externally forced response. Simulated unforced variability cannot explain the observed trends in the tropical Pacific, but we suggest that this is due to inadequate simulation of variability by CMIP5 AOGCMs, rather than evidence of anthropogenic change. We apply the method of pattern scaling to projections of sea level change and show that it gives accurate estimates of future local sea level change in response to anthropogenic forcing as simulated by the AOGCMs under RCP scenarios, implying that the pattern will remain stable in future decades. We note, however, that use of a single integration to evaluate the performance of the pattern-scaling method tends to exaggerate its accuracy. We find that ocean volume mean temperature is generally a better predictor than global mean surface temperature of the magnitude of sea level change, and that the pattern is very similar under the different RCPs for a given model. We determine that the forced signal will be detectable above the noise of unforced internal variability within the next decade globally and may already be detectable in the tropical Atlantic.

    Fully-automated regional brain volumetry based on structural magnetic resonance imaging (MRI) plays an important role in quantitative neuroimaging. In clinical trials as well as in clinical routine multiple MRIs of individual patients at different time points need to be assessed longitudinally. Measures of inter- and intrascanner variability are crucial to understand the intrinsic variability of the method and to distinguish volume changes due to biological or physiological effects from inherent noise of the methodology. To measure regional brain volumes an atlas based volumetry (ABV) approach was deployed using a highly elastic registration framework and an anatomical atlas in a well-defined template space. We assessed inter- and intrascanner variability of the method in 51 cognitively normal subjects and 27 Alzheimer dementia (AD) patients from the Alzheimer's Disease Neuroimaging Initiative by studying volumetric results of repeated scans for 17 compartments and brain regions. Median percentage volume differences of scan-rescans from the same scanner ranged from 0.24% (whole brain parenchyma in healthy subjects) to 1.73% (occipital lobe white matter in AD), with generally higher differences in AD patients as compared to normal subjects (e.g., 1.01% vs. 0.78% for the hippocampus). Minimum percentage volume differences detectable with an error probability of 5% were in the one-digit percentage range for almost all structures investigated, with most of them being below 5%. Intrascanner variability was independent of magnetic field strength. The median interscanner variability was up to ten times higher than the intrascanner variability. PMID:26723849

    This report is one of many supporting documents used by the Nuclear Regulatory commission in the preparation of the Nuclear Energy Center Site Survey (NECSS) mandated by Congress. While the overall study focuses on the feasibility and practicability of nuclear energy centers (NECs), this report is directed towards choosing a suitable surrogate site in the upper St. Lawrence region of New York State, assessing the probable impacts associated with construction and operation of the NEC, and comparing these impacts with those associated with small dispersed nuclear power stations. The upper St. Lawrence region is surveyed to identify a specific site that might be suitable for a surrogate NEC. Several assumptions about the basic design of an NEC are delineated, and a general overview of the characteristics of the region is given. The Fort Drum Military Reservation is chosen as a suitable surrogate site. Fort Drum and the surrounding area are described in terms of land use and population patterns, terrestrial and aquatic ecology, water use and quality, meteorology, institutional framework, and socioeconomic structure. The impacts associated with NEC development are assessed. Then the impacts associated with smaller dispersed nuclear power stations located throughout New York State are assessed and compared with the impacts associated with the NEC. Finally, the impacts due to development of the transmission line networks associated with the NEC and with the dispersed power stations are assessed and compared.

  2. Geochemistry and isotope evolution of groundwater flow and recharge from the uranium production center in Brazilian semi-arid region (Caetite-BA, Brazil) - Towards sustainability or shortage?

    International Nuclear Information System (INIS)

    The semi-arid region of the Northeast of Brazil is characterized by a lack of superficial waters due to the low pluviometric precipitation and high evaporation rates. Owing to these adverse climatic conditions, intense pressure is being put on the use of groundwater resources. However, there is still insufficient knowledge of the basic aquifers characteristics leading to an over exploitation of the water resources. The prevailance of crystalline rocks is connected to a fracture aquifer type of low productivity, where wells show, generally, yield rates lower than 3 m3·h-1. This work was developed in a semi-arid area located in the center-south region of Bahia State at 900 metres a.s.l., where were discovered several radioactive anomalies by aerogeophysical surveys performed during 70's decade, that allowed to set the uranium province named Lagoa Real. There were performed isotopic and geochemical analysis of groundwater sampled from twenty-five wells placed in crystalline rocks areas (granite or gneiss) covered by short layers of residual soil or alluvial sediments. The samples were analysed in a mass spectrometer for stable isotopic ratios, like δ2H, δ18O, δ13C (per mille VSMOW) and also measured for radiocarbon activity concentration (14C) to calculate the percentage of modern carbon (PMC) by AMS. The values of δ2H and δ18O defined a local evaporation line (LEL) with slope equal to 4.6 against the value of 7.4 for the Local Meteoric Water Line (Salvador station from 1972 to 1976). The radiocarbon ages, corrected by carbonate dissolution (through δ13C and DIC), showed very young waters that were recently recharged, perhaps during the last few years to several months. The supposed old ages for the fractured aquifer are not accomplished by radiocarbon dating, showing it is unconfined with no discharge of old groundwater through deep faults and short residence time. Thus, the groundwater offer for multiple uses (in terms of quantity) seems to be assured if the

    Full Text Available Abstract Background Day surgery should take place in appropriate organizational settings. In the presence of high volumes, the organizational models of the Lazio Region are represented by either Day Surgery Units within continuous-cycle hospitals or day-cycle Day Surgery Centers. This pilot study presents the regional volumes provided in 2010 and the additional volumes that could be provided based on the best performance criterion with a view to suggesting the setting up of a regional Freestanding Center of Pediatric Day Surgery. Methods This is an observational retrospective study. The activity volumes have been assessed by means of a DRG (Diagnosis Related Group-specific indicator that measures the ratio of outpatients to the total number of treated patients (freestanding indicator, FI. The included DRGs had an FI exceeding the 3rd quartile present in at least a health-care facility and a volume exceeding 0.5% of the total patients of the pediatric surgery and urology facilities of the Lazio Region. The relevant data have been provided by the Public Health Agency and relate to 2010. The best performance FI has been used to calculate the theoretical volume of transferability of the remaining facilities into freestanding surgery centers. Patients under six months of age and DRGs common to other disciplines have been excluded. The Chi Square test has been used to compare the FI of the health-care facilities and the FI of the places of origin of the patients. Results The DRG provided in 2010 amounted to a total of 5768 belonging to 121 types of procedures. The application of the criteria of inclusion have led to the selection of seven final DRG categories of minor surgery amounting to 3522 cases. Out of this total number, there were 2828 outpatients and 694 inpatients. The recourse of the best performance determines a potential transfer of 497 cases. The total outpatient volume is 57%. The Chi Square test has pointed to a statistically significant

    Full Text Available The Sanjiangyuan region is located on the Qinghai-Tibetan Plateau in western China and encompasses the headwaters of the Yangtze, Yellow and Mekong rivers. It is also home to 300,000 Tibetan pastoralists. The area is characterized by its significant ecological service, unique culture, and fragile ecosystems, and has undergone a rapid degradation over the past several decades. Traditional Tibetan culture offers alternative knowledge and perspectives that facilitate the environmental conservation throughout the region, but have yet to be recognized or adopted by the Chinese government. Beginning in 2007, the local environmental NGO, Shanshui Conservation Center, has initiated a journey to bridge Tibetan communities with the outside scientific community, mainstream society and policy-makers with the aim of advocating integrating traditional Tibetan practices in conservation actions in the Sanjiangyuan region. Through the conservation concession program initiated and facilitated by Shanshui Conservation Center in collaboration with Conservation International, the Sanjiangyuan nature reserve turned over the management of some reserve lands to local communities after a conservation agreement with clear management plans and monitoring indictors was made between the two parties. The trial and demonstration of the conservation concession program successfully led to the adoption of community-based conservation models in state level conservation policy in 2011. We demonstrate as a bridging organization, Shanshui Conservation Center plays the role of cultural translator to promote the understanding and appreciation of traditional Tibetan culture in conservation in western China.

    Background and aims Orofacial pain is one of the most common reasons for attendance at the dental clinic. The prevalence and the sources of orofacial pain vary from place to place and patients’ response to pain also differs. The aim of this study was to determine the prevalence and pattern of orofacial pain as well as the factors influencing patients’ response to orofacial pain among patients presenting for dental treatment in our center. Materials and methods Consecutive patients presenting with orofacial pain at the Dental Center, University of Port Harcourt Teaching Hospital during the one-year period of the study were recruited into the study. Patients’ demographic data were collected and recorded in special forms. Patients were later examined to confirm the specific cause of pain. This was also recorded. Data generated were analyzed using SPSS for Windows. Results Four hundred and forty-eight patients out of the 2,426 patients seen during the study period had orofacial pain, yielding a prevalence rate of 18.5%. There were 255 females and 193 males with most patients in the 17-27-year age group (49.1%). Lower jaw was commonly affected. Most patients presented after a period of at least one month, with severe and spontaneous pain. Most patients had drug therapy before presentation. Caries was the most common source of orofacial pain. Conclusion Orofacial pain was not uncommon in our center and it accounted for about 20% of patients’ attendance in the center. Dental caries and periodontal diseases were the most common sources of orofacial pain while temporomandibu-lar joint pain and atypical facial pain were not common in our center. Young adults and females were most commonly affected. PMID:22991595

  10. Quantification of changes in water balance and sediment transport due to recent and future land use change in the Xiangxi Catchment (Three Gorges Region)

    The construction of the Three Gorges Dam on the Yangtze River induced a large-scale land use change in the Three Gorges Region in Central China. The relocation of towns, villages and agricultural areas is assumed to impact the water balance and increase erosion rates as well as sediment yields in the affected catchments. At the same time, an increasing risk of reservoir eutrophication can be expected because of higher inputs of nutrients, especially phosphorus, adsorbed to sediment and due to reduced flow velocities and prolonged residence times of water in the reservoir. As field experiments are often labor- and time-intensive and do not provide the possibility to analyze the effect of management decisions prior to their implementation, hydrologic and water quality models are frequently used to assess the impact of land use changes on water resources. In this study, the eco-hydrological model SWAT was applied to the Xiangxi Catchment in the Three Gorges Region in order to simulate stream flow and sediment loads at Xingshan gauging station under changing land use conditions. For the baseline scenario, a land use map for the year 1987 was used. The calibration of stream flow resulted in a good fit of simulated and observed data, which is indicated by NSE values of 0.69 and 0.67 for the calibration and validation periods, respectively. In contrast, the model was not able to simulate the monthly average sediment loads correctly as indicated by very low NSE values of 0.42 (calibration) and 0.07 (validation). This is mainly due to insufficient input data because of a very low density of rain gauges in the Xiangxi Catchment. Also, there is very high uncertainty in the observed sediment data. Nevertheless, the modeling results prove the general applicability of SWAT to the Xiangxi Catchment and provide a sufficient basis for the simulation of land use scenarios. Land use maps for the years 1999 and 2007 were used to quantify the changes in water balance and sediment

    Full Text Available Introduction There is currently no consensus regarding the best method for predicting the changes in soft tissues due to the modification of hard tissues in orthognathic surgery. Objective To measure the changes in soft tissues of the upper lip, lower lip, and chin regions due to the modifications of hard tissues caused by orthognathic maxillary advancement surgery using a cephalometric methodology. Methods The study was conducted on 35 patients with dentoskeletal and facial deformities submitted to orthognathic maxillary advancement surgery. Two teleradiographs were taken: one during the preoperative period and the other 1 year after the surgery, on which the cephalometric tracing was drawn. Results A strong correlation (r = 0.747 was demonstrated in the horizontal analysis between the hard A (Ah point (located in the deepest point of the anterior curvature of the maxilla and the soft A (As point in the advancement of the maxilla, with a mean variation of 0.859% occurring in As with each 1% variation of the Ah point. A mean variation of 0.698% occurred in the superior soft prostion point (prolongation of the superior hard prostion point to its corresponding point on soft tissue for each 1% variation in the superior hard prostion point (bone point located at the junction of the alveolar process with the crown of the upper incisors. Conclusion The cephalometric methodology applied here revealed that the soft tissues of the upper lip accompanied 70 to 80% of the movement of hard tissues in maxillary advancement and that the soft tissues of the lower lip did not change or showed no significant changes.

  12. Behaviour of rare earth elements, thorium, uranium and strontium isotopes in soil samples of Bryansk region contaminated due to Chernobyl accident

    International Nuclear Information System (INIS)

    The aim of this study was to characterise the processes which control retention of rare earth elements, U and Th in soil samples of Bryansk region in one of Russian territory contaminated due to Chernobyl accident. Acid sandy and loam sand podzolic soils are typical of this area. We have classified soil samples into forest, pasture, field, yard and kitchen garden. Rare earth elements, U and Th concentrations were measured by digestion soil samples using acid digestion and microwave digestion method followed by ICP-MS whereas Sr isotope ratio (87Sr/86Sr) was determined by using a thermal ionization mass spectrometer (TIMS). In case of forest soil samples, ratio of U/Th varied from 3.32 to 3.60. Though concentration of U and Th varies, ratio does not show much variation. Pasture soil showed higher concentration of REEs, U and Th. Chondrite normalized pattern of soil samples did not differ much from one another excep Ce and Eu and were similar to that for average concentration of continental crust. In case of 87Sr/86Sr ratio, top layer soil sample shows a relatively higher isotope ratio than lower layers. These data, within the study area, may be reflective of variations in the concentration of elements in reservoir rocks at depth. (author)

    2012-01-01

    Chronologies for eruptive activity of the Lassen Volcanic Center and for eruptions from the regional mafic vents in the surrounding area of the Lassen segment of the Cascade Range are here used to estimate probabilities of future eruptions. For the regional mafic volcanism, the ages of many vents are known only within broad ranges, and two models are developed that should bracket the actual eruptive ages. These chronologies are used with exponential, Weibull, and mixed-exponential probability distributions to match the data for time intervals between eruptions. For the Lassen Volcanic Center, the probability of an eruption in the next year is 1.4x10-4 for the exponential distribution and 2.3x10-4 for the mixed exponential distribution. For the regional mafic vents, the exponential distribution gives a probability of an eruption in the next year of 6.5x10-4, but the mixed exponential distribution indicates that the current probability, 12,000 years after the last event, could be significantly lower. For the exponential distribution, the highest probability is for an eruption from a regional mafic vent. Data on areas and volumes of lava flows and domes of the Lassen Volcanic Center and of eruptions from the regional mafic vents provide constraints on the probable sizes of future eruptions. Probabilities of lava-flow coverage are similar for the Lassen Volcanic Center and for regional mafic vents, whereas the probable eruptive volumes for the mafic vents are generally smaller. Data have been compiled for large explosive eruptions (>≈ 5 km3 in deposit volume) in the Cascade Range during the past 1.2 m.y. in order to estimate probabilities of eruption. For erupted volumes >≈5 km3, the rate of occurrence since 13.6 ka is much higher than for the entire period, and we use these data to calculate the annual probability of a large eruption at 4.6x10-4. For erupted volumes ≥10 km3, the rate of occurrence has been reasonably constant from 630 ka to the present, giving

    We have developed a tool for measuring the evolutional stage of the space weather regional warning centers using the approach of the innovative evolution starting from the perspective presented by Figueiredo (2009, Innovation Management: Concepts, metrics and experiences of companies in Brazil. Publisher LTC, Rio de Janeiro - RJ). It is based on measuring the stock of technological skills needed to perform a certain task that is (or should) be part of the scope of a space weather center. It also addresses the technological capacity for innovation considering the accumulation of technological and learning capabilities, instead of the usual international indices like number of registered patents. Based on this definition, we have developed a model for measuring the capabilities of the Brazilian Study and Monitoring Program Space Weather (Embrace), a program of the National Institute for Space Research (INPE), which has gone through three national stages of development and an international validation step. This program was created in 2007 encompassing competence from five divisions of INPE in order to carry out the data collection and maintenance of the observing system in space weather; to model processes of the Sun-Earth system; to provide real-time information and to forecast space weather; and provide diagnostic their effects on different technological systems. In the present work, we considered the issues related to the innovation of micro-processes inherent to the nature of the Embrace program, not the macro-economic processes, despite recognizing the importance of these. During the development phase, the model was submitted to five scientists/managers from five different countries member of the International Space Environment Service (ISES) who presented their evaluations, concerns and suggestions. It was applied to the Embrace program through an interview form developed to be answered by professional members of regional warning centers. Based on the returning

    International Nuclear Information System (INIS)

    As part of a settlement agreement between the US DOE and the State of Texas, DOE proposes to transfer $65 million of federal funds to the Texas National Research Laboratory Commission (TNLRC) for construction of the Regional Medical Technology Center (RMTC) to be located in Ellis County, Texas. The RMTC would be a state-of-the-art medical facility for proton cancer therapy, operated by the State of Texas in conjunction with the University of Texas Southwestern Medical Center. The RMTC would use the linear accelerator assets of the recently terminated DOE Superconducting Super Collider Project to accelerate protons to high energies for the treatment of cancer patients. The current design provides for treatment areas, examination rooms, support laboratories, diagnostic imaging equipment, and office space as well as the accelerators (linac and synchrotron) and beam steering and shaping components. The potential environmental consequences of the proposed action are expected to be minor

    2006-01-01

    (Abridged) The inner couple hundred pcs of our Galaxy is characterized by significant amount of synchrotron-emitting gas, which appears to co-exist with a large reservoir of molecular gas. The spatial correlation between fluorescent Fe K-alpha line emission at 6.4 keV and molecular line emission from Galactic center molecular clouds has been explained as reflected X-rays from a past outburst of Sgr A*. Here we present multi-wavelength study of a representative Galactic center cloud Sgr C using Chandra, VLA and FCRAO. We note a correlation between the nonthermal radio filaments in Sgr C and the X-ray features, suggesting that the two are related. We account for this distribution in terms of the impact of the relativistic particles from local (nonthermal filaments) and extended sources with diffuse neutral gas producing both a nonthermal bremsstrahlung X-ray continuum emission, as well as diffuse 6.4 keV line emission. The production rate of Fe Kalpha photons associated with the injection of electrons into a cl...

  19. Neutron star population in the Galactic center region as a potential source of polarized X-ray emission

    2016-06-01

    We analyse the emission properties of neutron stars that are predicted to exist in large numbers of the order of 10000 in the innermost parts of the Galactic center. A part of the population of isolated neutron stars propagates supersonically through denser ionized streams of the Minispiral (Sgr A West), forming bow shocks where particles are accelerated and are expected to produce polarized X-ray synchrotron signal. Another source of the synchrotron emission is an elongated magnetosphere and tail. We investigate whether the polarized X-ray emission from Galactic center neutron stars will be potentially detectable in the framework of future X-ray polarimeters. A special case is a detected young neutron star - magnetar SGRJ1745-2900 - that has undergone a series of outbursts with a peak X-ray luminosity of the order of 10^{35} erg s^{-1} (1-10 keV). Apart from an intrinsic X-ray emission, the X-ray emission from neutron star outbursts may be scattered by molecular clouds in the Central Molecular Zone by Thomson scattering, which is another potential source of polarized X-ray emission.

  20. A New High Energy Resolution Neutron Transmission Detector at the Gaerttner LINAC Center and Isotopic Molybdenum Total Cross Section Measurements in the keV-Region

    Science.gov (United States)

    Bahran, Rian M.

    The Gaerttner LINAC Center at Rensselaer Polytechnic Institute is home to a 60 MeV electron linear accelerator (LINAC) that is used as a pulsed neutron source for TOF nuclear data experiments. High energy resolution total cross section measurements for the stable molybdenum isotopes of Mo-95, Mo-96, Mo-98, and Mo-100 were performed with a newly developed modular neutron transmission detector positioned at a 100 m experimental flight station. This work is part of an effort to both improve existing neutron total cross section libraries and measurement capabilities at the Gaerttner LINAC Center in and above the resolved resonance energy region (from 5-620 keV). The overall design optimization process and qualification of the new high resolution detector is presented. Additionally, a new method to quantify the energy-dependent neutron and gamma-ray experimental background of the detector was developed. High resolution isotopic molybdenum total cross section data are of particular importance because stable Mo isotopes can be found in significant concentrations in a nuclear fuel cycle either as a high yield fission product or in alloyed form with applications in reactor piping, fuel cladding, and as an advanced nuclear fuel in the form of U-Mo. The measured total cross section energy range encompasses the resolved resonance region and extends into the unresolved resonance region for each molybdenum isotope. New high accuracy resonance parameters for Mo-95 were generated from fitting experimental data using the multilevel R-matrix Bayesian code SAMMY in the resolved resonance region. In the unresolved resonance region, average resonance parameters and fits to the total cross section were obtained using the Hauser-Feshbach statistical model code FITACS which is embedded in SAMMY.

    The cessation of hostilities between India and Pakistan is an immediate need and of global concern, as these countries have tested nuclear devices, and have the capability to deploy nuclear weapons and long-range ballistic missiles. Cooperative monitoring projects among neighboring countries in South Asia could build regional confidence, and, through gradual improvements in relations, reduce the threat of war and the proliferation of weapons of mass destruction. This paper discusses monitoring the trans-border movement of flow and sediment in the Indian and Pakistani coastal areas. Through such a project, India and Pakistan could initiate greater cooperation, and engender movement towards the resolution of the Sir Creek territorial dispute in their coastal region. The Joint Working Groups dialogue being conducted by India and Pakistan provides a mechanism for promoting such a project. The proposed project also falls within a regional framework of cooperation agreed to by several South Asian countries. This framework has been codified in the South Asian Seas Action Plan, developed by Bangladesh, India, Maldives, Pakistan and Sri Lanka. This framework provides a useful starting point for Indian and Pakistani cooperative monitoring in their trans-border coastal area. The project discussed in this paper involves computer modeling, the placement of in situ sensors for remote data acquisition, and the development of joint reports. Preliminary computer modeling studies are presented in the paper. These results illustrate the cross-flow connections between Indian and Pakistani coastal regions and strengthen the argument for cooperation. Technologies and actions similar to those suggested for the coastal project are likely to be applied in future arms control and treaty verification agreements. The project, therefore, serves as a demonstration of cooperative monitoring technologies. The project will also increase people-to-people contacts among Indian and Pakistani policy

    .4, 2.2±1.1, -1.4±1.4, -0.15±0.13, while, surface ARF is -16.4±3.1, -7.6±1.7, -31.5±4.7, -17.1±8.4, respectively for the MAMJ, JAS, ON and DJF seasons. Post-monsoon and winter season shows negative values of TOA ARF, hence suggest 'cooling'. The associated heating rate profiles show higher values for 'WS-BC+Dust+WINS' case as compared to other cases, with relatively large values during the winter and post-monsoon seasons, while lower value was observed for 'BC-WINS+WS+Dust'. We examined the modulation of clear sky ARF by 'water-cloud' and 'ice-cloud' separately. The seasonal mean ARF for both water and ice clouds show nearly similar characteristics as observed for clear-sky case, with relatively large ARF at TOA and surface in water cloud case as compared to ice cloud during all the seasons. As a result, the associated heating rate is also relatively higher in water cloud case as compared to ice cloud. Such large modulation of ARF due to mixing state calls for a coordinated effort to create a mixing state database for this region to reduce the uncertainty in climate forcing.

    1992-04-01

    The experiments discussed in this thesis focus on identifying the protein segments or specific amino acids which provide ligands to the Mn cluster of photosystem II (PS II). This Mn cluster plays a central role in the oxygen-evolving complex (OEC) of PS II. The Mn cluster is thought to be bound by lumenal regions of the PS II reaction center proteins known as D1 and D2. First, several peptides were synthesized which correspond to specific lumenal segments of the D1 and D2 proteins. Next, polyclonal antibodies were successfully elicited using three of these peptides. The peptides recognized by these antibodies correspond to protein segments of the spinach reaction center proteins: Ile-321 to Ala-344 of D1 (D1-a), Asp-319 to Arg-334 of D1 (D1-b), and Val-300 to Asn-319 of D2 (D2-a). These antibodies were then used in assays which were developed to structurally or functionally probe the potential Mn-binding regions of the D1 and D2 proteins.

  10. Effect of Dynamic Center Region on the Flow and Mixing Efficiency in a New Tri-Screw Extruder Using 3D Finite Element Modeling

    Full Text Available Three-dimensional finite element modeling of polymer melt flowing in a new co-rotating tri-screw extruder was established with mesh superposition technique. Based on the particle tracking technology, three typical particle trajectories in the tri-screw extruder were calculated using a 4th-order-Runge-Kutta method to study the dynamic motions of the particles. Then the flow visualizations in the local center region were carried out. Moreover, the dispersive, distributive and stretching mixing efficiencies of the tri-screw and twin-screw extruders were compared, respectively. The results show that when the particles move from one screw to another, there are great abrupt changes in the velocities and displacements, which induce the abrupt change in the stress magnitude. Most of particles, which are initially distributed in the inlet plane of the center region, fast flow out the outlet and don’t pass through any screw. This special phenomenon induces a series of new characteristics in the residence time distribution (RTD, flow number, segregation scale and time averaged efficiency. In comparison with the twin-screw extruder, the tri-screw extruder has better mixing efficiency.

    Full Text Available BACKGROUND: This research was conducted for the purpose of determining the status of women's use of iodized salt, their knowledge about the subject, their habits and practice of using iodized salt. METHODS: The surveys were completed between March 01 and May 20, 2005. A total of 1454 women a random sample were reached for this study in the primarily slum area covered by two public health centers in Antalya. Face to face interviewing on knowledge and practices of women about iodized salt were investigated on 1454 women. Data obtained were loaded on the computer and evaluated using the SPSS program using percentage and Chi square test and Binary Logistic Regression Analysis. Basic descriptive analysis of the data was performed using frequency distributions. RESULTS: Knowledge and practices of women about iodized salt were investigated on 1454 women through face to face interviewing. It was determined that 18.2% of the women knew what iodine was, 23.6% stated that they knew what problems occurred with iodine deficiency, and 7.1% had been diagnosed with goiter. Less than half (48.3% of the women made sure that the salt they bought was iodized, but 69.9 % stated that they used iodized salt in their homes. As the educational level of the women increased their knowledge about iodine, their making sure the salt they bought was iodized, use of iodized salt at home, and storing salt in a closed cupboard increased at significant levels (p<0.001. CONCLUSION: In Antalya province municipality one in three women did not use iodized salt and the majority did not know that errors in its use decreased the effectiveness of iodine.

    At Mount Etna, the present-day active volcano is an open conduit structure characterized by continuous eruptive activity. Such conditions have been thought unique in the evolution of the Etnean volcano as well as in the Mediterranean region. However, a review study of available geophysical data and models, combined with geological records, petrographic and geochemical considerations, has led us to consider that a large area of about 28 km2 located in Val Calanna, on the eastern side of Valle del Bove, can be interpreted as the site of an old open conduit volcano. A dyke swarm outcrops in the area, whose deep alteration and fumarolization can be attributed to the sustained passage of volcanic gases over long periods. Radiometric dating yields an age of about 129 ka. This finding sheds new light on the evolution of Mount Etna volcano, indicating that the tectonic conditions leading to an open conduit volcano must also have been active in the past.

  14. Study of the electron-positron annihilation in the galactic center region with the Integral/SPI spectrometer

    International Nuclear Information System (INIS)

    A spectral feature was detected in 1970 in the gamma-ray emission from the central regions of the Milky Way, during balloon flight observations. Located near 511 keV, this feature was soon attributed to the gamma-ray line tracing the annihilation of electrons with their anti-particles, positrons. However, none of the multiple astrophysical scenarios contemplated to explain the production of positrons in the Galactic bulge has been able to reproduce the high injection rate deduced from the flux of the 511 keV line, close to 1043 positrons per second. Launched in 2002, the European gamma-ray satellite INTEGRAL was provided with a spectrometer, SPI, whose unprecedented imaging and spectral capabilities in this energy range enable us to further study the source of the 511 keV line detected in the Galactic centre region. Indeed, a better determination of the spatial extent of the source, the intrinsic width of the line and the fraction of positrons annihilating in-flight, directly or via the formation of ortho-Positronium atoms would improve our knowledge of both the annihilation medium and the initial source of positrons, and could allow us to discriminate between the various explanatory scenarios. The first part of this thesis deals with a key ingredient in the extraction of the annihilation spectrum: the optimization of the instrumental background model. New data screening and tracer selection procedures are presented. Classical multi-linear models are compared to neural and Bayesian networks. Finally, three years of observation are used to constrain the width of the source and derive its spectrum. The second part of the thesis focuses on one of the possible scenarios explaining the high positron injection rate deduced from the flux of the 511 keV line: the annihilation of light dark matter particles into electron-positron pairs. The various radiation mechanisms involved are modeled and confronted to observations in order to set an upper limit on the injection energy

    The 29-acre site was used for wood treating from the 1920s until 1980. In 1983 the site was listed on the National Priorities List due to extensive soil and ground-water contamination. The contaminants of concern at the site are pentachlorophenol (PCP), heavy metals (arsenic, chromium and copper), and carcinogenic and non-carcinogenic polynuclear aromatic hydrocarbons derived from creosote. Chlorinated dibenzo-p-dioxins and dibenzofurans, which are often found as impurities in PCP, are also of concern. Records indicate that wastes from wood-treating processes were disposed of into on-site waste ponds. Several large spills also occurred. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via ground water, surface water, and soil. Exposure via ingestion of wild life or inhalation of fugitive dusts is also possible, but the degree of exposure via these routes would be less.

  18. Dose rate estimates in the first optical enclosure due to particle beam loss in the insertion device transition region during injection

    International Nuclear Information System (INIS)

    The particle beam, during injection into the storage ring, can be partly lost in one of the transition regions between the storage-ring vacuum chamber and the insertion-device (ID) straight section. The transition region is a copper interface between a standard aluminum vacuum chamber and an insertion-device vacuum chamber. This can be a problem, at least in the first few insertion devices where the injected beam is still unstable. It may create higher photon and neutron dose rates in the first optical enclosures of the upstream ID beamlines adjacent to this region. This report presents the results of the dose rate estimates for such an event and some recommendations for mitigation

  3. Mutations induced at the promoter region of the c-myc gene due to dual exposure to ionizing radiation and methyl nitroso urea

    International Nuclear Information System (INIS)

    Malignant tumors were arising from a sequence of events including mutation in proto-oncogenes and tumor suppressor genes.The accretion of these mutations is apparently facilitated by acquired or inherited defects inguardianmechanisms that maintain the integrity of the cellular genome. The proto-oncogene c-myc, which is frequently over expressed in tumors at the center of a transcription factor network, requlates cellular proliferation replicate potential, growth, differentiation and apoptosis. Expression of c-myc is down reglated during differentiation and is rapidly induced by a diverse catalog of mutagens including ionizing radiation and many alkylating agents. In the present study, the dual exposure to methyl nitroso urea(MNU) and ionizing radiation were assessed. These induced effects were assessed histopathologically and biochemically and were correlated at the molecular level by assessing single strand conformation polymorphism (SSCP)

  4. Environmental Assessment for the construction and operation of the Three Rivers Solid Waste Authority regional waste management center at the Savannah River Site

    International Nuclear Information System (INIS)

    This Environmental Assessment (EA) has been prepared by the US Department of Energy (DOE) to assess the potential environmental impacts associated with the construction and operation of a landfill and technology center for regionally-generated municipal solid waste at the Savannah River Site (SRS) near Aiken, South Carolina. The facility would serve the municipal solid waste disposal needs for SRS and at least nine of the surrounding counties who currently comprise the Three Rivers Solid Waste Authority (TRSWA). Additional counties could become included in the proposed action at some future date. Current Federal and state requirements do not afford individual counties and municipalities within the region encompassing SRS the ability to efficiently or economically operate modern waste management facilities. In addition, consolidation of regional municipal solid waste at one location would have the benefit of reducing the duplicity of environmental consequences associated with the construction and operation of county-level facilities. The option to seek a combined disposal and technology development facility based on a regionally-cooperative effort was selected as a viable alternative to the existing individual SRS or county disposal activities. This document was prepared in compliance with the National Environmental Policy Act (NEPA) of 1969, as amended, the requirements of the Council on Environmental Quality Regulations for Implementing NEPA (40 CFR Part 1021). NEPA requires the assessment of environmental consequences of Federal actions that may affect the quality of the human environment. Based on the potential for impacts described for impacts described herein, DOE will either publish a Finding of No Significant Impact or prepare an environmental impact statement (EIS)

    Context. The forbidden fine structure transition of C+ at 158 μm is one of the major cooling lines of the interstellar medium (ISM). Aims: We aim to understand the contribution of the ionized, atomic, and molecular phases of the ISM to the [C ii] emission from clouds near the dynamical center and the BCLMP302 H ii region in the north of the nearby galaxy M 33 at a spatial resolution of 50 pc. Methods: We combine high-resolution [C ii] spectra taken with the HIFI spectrometer onboard the Herschel satellite with [C ii] Herschel-PACS maps and ground-based observations of CO(2-1) and H i. All data are at a common spatial resolution of 50 pc. Correlation coefficients between the integrated intensities of [C ii], CO(2-1) and H i are estimated from the velocity-integrated PACS data and from the HIFI data. We decomposed the [C ii] spectra in terms of contribution from molecular and atomic gas detected in CO(2-1) and H i, respectively. At a few positions, we estimated the contribution of ionized gas to [C ii] from the emission measure observed at radio wavelengths. Results: In both regions, the center and BCLMP302, the correlation seen in the [C ii], CO(2-1) and H i intensities from structures of all sizes is significantly higher than the highest correlation in intensity obtained when comparing only structures of the same size. The correlations between the intensities of tracers corresponding to the same velocity range as [C ii], differ from the correlation derived from PACS data. Typically, the [C ii] lines have widths intermediate between the narrower CO(2-1) and broader H i line profiles. A comparison of the spectra shows that the relative contribution of molecular and atomic gas traced by CO(2-1) and H i varies substantially between positions and depends mostly on the local physical conditions and geometry. At the positions of the H ii regions, the ionized gas contributes between 10-25% of the observed [C ii] intensity. We estimate that 11-60% and 5-34% of the [C ii

    This study broadens the archaeological research of the the Bezděz - Doksy region in Northern Bohemia, Czech Republic (Dreslerová et al., 2013). Extensive field works between 2008 and 2012 showed that the region has been settled since the La Tène period. Survey of the alluvial plain of the Robečský stream revealed a record of two intensive erosion episodes in the catchment. We suppose that the first episode may be connected to land use changes and the beginnings of agriculture at the site in the La Tène period. The second episode may be connected to the foundation of the medieval village of Okna, which came into existence in the vicinity of the La Tène settlement. The accelerated erosion of former albeluvisols (on loess) led to significant changes of landscape in the region. The aim of this contribution is to bring a reconstruction of soils, vegetation and relief at the site of Okna before the human occupancy and to detect landscape changes over the time. It focuses on the hypothesis that the accelerated soil erosion has been occurring at the site since the first anthropogenic influence like it is demonstrated by other studies in Europe (e.g. Leopold and Völkel, 2007; Boardman, 2013). An abrupt change of land use from forest to arable land is proved by palynological records. Simultaneously there are buried soil horizons and alluvial sediments which can be studied as geoarchives. The difficulties in reconstruction of relief and quantification of the historical erosion effects are faced by applying GIS and model approaches (Peeters et al., 2003). References Boardman, J., 2013.

    We investigate the origin of the diffuse 6.4 keV line emission recently detected by Suzaku and the source of H{sub 2} ionization in the diffuse molecular gas of the Galactic center (GC) region. We show that Fe atoms and H{sub 2} molecules in the diffuse interstellar medium of the GC are not ionized by the same particles. The Fe atoms are most likely ionized by X-ray photons emitted by Sgr A* during a previous period of flaring activity of the supermassive black hole. The measured longitudinal intensity distribution of the diffuse 6.4 keV line emission is best explained if the past activity of Sgr A* lasted at least several hundred years and released a mean 2-100 keV luminosity {approx}> 10{sup 38} erg s{sup -1}. The H{sub 2} molecules of the diffuse gas cannot be ionized by photons from Sgr A*, because soft photons are strongly absorbed in the interstellar gas around the central black hole. The molecular hydrogen in the GC region is most likely ionized by low-energy cosmic rays, probably protons rather than electrons, whose contribution into the diffuse 6.4 keV line emission is negligible.

    The irreversibility due to laminar forced convection in the entrance region of a duct was studied by means of numerical simulation. Local entropy generation distributions and total entropy generation were obtained based on the entropy generation equation. The effect of Reynolds number on the irreversibility was studied for constant wall temperature and heat flux. The results showed that the irreversibility in the entrance region was different from that in the fully developed region. Reynolds number had a strong effect on the irreversibility in the entrance region. The entropy generation caused by temperature difference was relatively dominant over that caused by viscous flow. The irreversibility at constant wall temperature was different from that at constant wall heat flux.

    In the past decade, developing countries have been experiencing rapid land use and land cover changes, including deforestation and cultivation of previously forested land. However, little is known about the impact of deforestation and land-use changes on the life history of malaria vectors and their effects on malaria transmission. This study examined the effects of deforestation and crop cultivation on the adult survivorship of major malaria mosquitoes, Anopheles sinensis and An. minimus in the China-Myanmar border region. We examined three conditions: indoor, forested, and banana plantation. Mean survival time of An. sinensis in banana plantation environment was significantly longer than those in forested environment, and mosquitoes exhibited the longest longevity in the indoor environment. This pattern held for both males and females, and also for An. minimus. To further test the effect of temperature on mosquito survival, we used two study sites with different elevation and ambient temperatures. Significantly higher survivorship of both species was found in sites with lower elevation and higher ambient temperature. Increased vector survival in the deforested area could have an important impact on malaria transmission in Southeast Asia. Understanding how deforestation impacts vector survivorship can help combat malaria transmission. PMID:27171475

  16. Radiation dose due to radon, thoron and their progeny concentration in indoor atmosphere around granite regions of Tumkur district, Karnataka, India

    International Nuclear Information System (INIS)

    The levels of indoor radon and thoron concentrations in the dwellings of granite regions of Tumkur district have been determined by using solid state nuclear track detector based double chamber dosimeters (LR-115, type II plastic track detector). The indoor radon and thoron concentrations were found to vary from 33.6±2.9 to 96.1±3.7 Bq m-3 with an average value of 50.04±3.32 Bq m-3 and 11.6±1.2 to 65.3±3.3 Bq m-3 with an average value of 34.93±2.59 Bq m-3 respectively. Their progeny concentrations were found to vary from 0.55±0.1 to 7.1±2.3 mWL with an average value of 3.28±1.12 mWL, while thoron progeny concentrations vary from 0.15±0.06 to 4.5±1.32 mWL with an average value of 1.98±0.89 mWL respectively. The overall average radon concentrations are found to be less than the lower reference level of 200 Bq m-3 of the International Commission on Radiological Protection (ICRP 2007). The average annual effective doses in present study area are found to vary from 1.24 to 4.23 mSv with an average value of 2.42 mSv. The obtained results are much lower than the upper reference level of 10 mSv (ICRP 2007). The annual exposure to occupants, annual effective dose and lifetime fatality risk in dwellings varied from 0.024 to 0.417 WLM with an average value of 0.189 WLM, 0.091 to 1.545 mSv with an average value of 0.701 mSv and 0.072 x10-4 to 1.251 x 10-4 with an average value of 0.567 x 10-4 respectively.

    Land subsidence due to groundwater over-exploitation is a deformation process affecting many cities around the world. This type of subsidence develops gradual vertical deformations reaching only a few centimeters per year, but can affect large areas. Consequently, inhabitants of subsiding areas are not aware of the process until others effects are observed, such as ground surface faulting, damage to building, or changes in the natural superficial drain. In order to mitigate and forecast subsidence consequences, it is useful to conduct numerical modeling of the subsidence process. Modeling the subsidence includes the following three basic tasks: a) Delimitation of the shape of the deforming body; b) Determination of the forces that are causing the deformations; and c) Determination of the mechanical properties of the deforming body according with an accepted rheological model. In the case of a land subsidence process, the deforming body is the aquifer system that is being drained. Usually, stratigraphic information from pumping wells, and other geophysical data are used to define the boundaries and shape of the aquifer system. The deformation governing forces, or stresses, can be calculated using the theory of "effective stress". Mechanical properties are usually determined with laboratory testing of samples from shallow strata, because the determination of these properties in samples from the deepest strata is economically or technically unviable. Consequently, the results of the numerical modeling do not necessarily match the observed subsidence evolution and ground faulting. We present in this work numerical simulation results of the land subsiding of the Valley of Aguascalientes, Mexico. Two analyses for the same subsiding area are presented. In the first of them, we used the mechanical properties of only the shallow strata, whereas in the second analysis we used "macroscopic" mechanical properties data determined for the whole aquifer system using In

    This report documents the archaeological investigation of Site 7 of the proposed Three Rivers Regional Landfill and Technology Center in Aiken County on the United States Department of Energy`s Savannah River Site (SRS) in Aiken and Barnwell Counties, South Carolina. Pedestrian and subsurface survey techniques were used to investigate the 1,403-acre project area. Survey resulted in the discovery of 23 previously unrecorded sites and 11 occurrences; six previously recorded sites were also investigated. These sites consist of six prehistoric sites, nine historic sites, and 14 sites with both prehistoric and historic components. Sites locations and project area boundaries are provided on a facsimile of a USGS 7.5 topographic map. The prehistoric components consist of very small, low-density lithic and ceramic scatters; most contain less than 10 artifacts. Six of the prehistoric components are of unknown cultural affiliation, the remaining prehistoric sites were occupied predominately in the Woodland period. The historic sites are dominated by postbellum/modem home places of tenant and yeoman farmers but four historic sites were locations of antebellum house sites (38AK136, 38AK613, 38AK660, and 38AK674). The historic sites also include an African-American school (38AK677).

    Full Text Available The seasonality of Alphitobius diaperinus population was studied during different seasons during one year, in broiler facilities located in the center-north region of the State of São Paulo. Parasite counting was weekly carried out by the use of traps adapted from the modified model of Arends. During the experimental period, facilities were not submitted to chemical treatment, and the litter was changed between flocks. A lower number of adults and larvae was observed during autumn, with the peak registered in the summer. There was no significant difference between spring and winter averages (adults and larvae, and between spring and summer averages (adults. Average temperatures in the facilities varied from 23.4ºC (winter to 27.1ºC (spring. The environmentally controlled systems used by the broiler industry provide an adequate habitat for A. diaperinus development. The continuous monitoring of the population of this parasite is essential for designing control strategies, and this can be accomplished by utilizing the traps used in the present experiment.

    关于中东路权益的交涉,是伴随铁路修建开始的,到上世纪20年代初,中俄双方先后签订了、后,交涉中的矛盾并未因此而结束.张学良执掌东北军政后,为争取两协定赋予中方的权益,对苏采取了强硬的交涉手段,导致中东路事件的发生.中东路事件发生后,致使收回中东路权益的目标未能实现.客观分析,张学良收回中东路权益的初衷及强硬立场是正确的,但他对内外局势的错误判断,并接受蒋介石"武力接管"中东路的主张是错误的.从外交史上看,这一教训是深刻的.%The negotiation on China's interests in the railways with Harbin as the center in Northeast China had begun as early as they were about to construct. Although the Sino-Russia Treaty and Fengtian-Russia Treaty had been signed in the early 1920s, the conflicts were not settled through negotiation. After the whole Northeast China fell into Peter H. L. Chang's power including the military and politics, he took an intransigent attitude in negotiation to strive against the former USSR for the interests as stipulated in the two treaties. As a result, an armed conflict happened due to China's interests in those railways. However, Peter H. L. Chang had not attained his goal, i.e., the interests in those railways couldn't be retaken. In an objective view of the historical incident, his original intention and unyielding standpoint of retaking the interests in those railways were regarded as positive, but his judgment about the domestic and international political situation at that time were wrong, especially his wrong acceptance of Chiang Kai Shek's proposition that all those railways should be taken over through military force. It was really a bitter experience in the perspective of diplomatic history.

  2. Assessment of health risks due to toxic metals and naturally occurring radioactive materials in the Birim river in East Akim Municipality of the Eastern Region Ghana

    International Nuclear Information System (INIS)

    A detailed study has been carried out to determine the health risk associated with the level of trace metals and naturally occurring radioactive materials in the Birim River in East Akim Municipality of the Eastern Region of Ghana. The river runs through several communities in the municipality and serves as the main source of drinking water, irrigation and for domestic purposes. However, small-scale mining activities in the area are deteriorating the quality of the river water. Results of the study show that water from the Birim River is polluted with respect to Hg, As and Fe. The most polluted sampling points were Adadientem and Kibi. Turbidity levels in water samples were between 2 – 708 NTU. Results from Principal Component Analysis/Factors Analysis (PCA/FA) analyses in November suggest high loading of phosphate (0.934) and chloride (0.802). High level of Hg was recorded in sediment samples from Adadietem (Ad-1) (0.4 mg/kg), KTC-6, (0.775 mg/kg), Kyebi Training College (KDS-5), (0.55 mg/kg), Bonsu-Accra Road (B-AR-10) (0.575 mg/kg) and Bonsu Bridge (BB-8) (0.4 mg/ kg) while at all the sampling points, high levels of As and Fe were recorded. As levels ranged between 8.40 mg/kg and 16.25 mg/kg while mean Fe levels were 821.62 – 837.81 mg/kg. Health risk assessment shows that Fe, Mn, As, Zn and Hg metals were the main contributors for ingestion and dermal exposures to the human environment in the river. The levels of Hazard Quotient (HQing) for As was greater than one, indicating that it could have harmful effects on human health. This is an indication that risk may occur via the ingestion of contaminated water in the municipality. As, Fe, Hg, Mn and Cr were found to be the main contributors to non-carcinogenic risk (HI) from the Birim River in Kibi Municipality. Carcinogenic risk (CRing) was found to be associated with the slight elevated value of As. The calculated average activity concentration of 232Th was higher than WHO guidance level of 1.0 Bq/L in water

    Because burn care in the United States is regionalized, burn patients are often transported across state lines to receive their burn treatment. The authors hypothesized that there are differences between in-state and out-of-state reimbursement for burn care. This project was conducted by the American Burn Association (ABA) Government Affairs Committee through the ABA Multicenter Trials Group. Participation was open to any member of the ABA. This retrospective observational study was approved by the institutional review boards of each participating institution. Subjects were identified using registry of each site, selecting patients hospitalized for burn injuries during FY2004-FY2006 of the hospitals. Once identified by the registry, the ID numbers were used to collect billing and reimbursement data from the financial offices. Data were sorted by age (adult and pediatric), location (in state and out of state), and payor source (Medicare, Medicaid, commercial, workers compensation, and self-pay). The rate of reimbursement was calculated based on charges and recoveries. Comparisons on data of each center were performed using Student's t-test with type I error <1%. Six facilities contributed data. A total of 4850 burn patients were reviewed, of whom 3941 were in-state burn patients and 909 were out-of-state burn patients. When the results from all six states were analyzed together, reimbursement for adults from Medicaid and Medicare was higher for in-state patients than for out-of-state patients. However, when analyzed by state, Medicare reimbursement between in-state and out-of-state patients did not differ significantly. In one state (Kansas), in-state Medicaid reimbursement was higher, but in two others (Arizona and Pennsylvania), in-state Medicaid reimbursement was lower than that for out-of-state reimbursement. Reimbursement for the care of children did not differ significantly based on state of residence. From these data, we conclude that there are indeed

    In China, Community Health Centers (CHCs) are major providers of primary care services, but their potential in empowering patients' self-management capacity has not been assessed. This study aims to describe self-care practice patterns amongst CHC attendees in urban China.In this cross-sectional quantitative study, 3360 CHC patients from 6 cities within the Pearl Delta Region were sampled using multistage cluster sampling.Thirty-seven per cent had used with over-the-counter Chinese herbal medicines (OTC CHMs) in the past year and majority of respondents found OTC CHMs effective. OTC CHMs were more popular amongst those who needed to pay out of pocket for CHC services. Less than 10% used vitamins and minerals, and those with a lower socioeconomic background have a higher propensity to consume. Although doubts on their usefulness are expressed, their use by the vulnerable population may reflect barriers to access to conventional health care, cultural affinity, or a defense against negative consequences of illnesses. About 25% performed physical exercise, but the prevalence is lower amongst women and older people. Taiji seems to be an alternative for these populations with promising effectiveness, but overall only 6% of CHC attendees participated.These results suggest that CHCs should start initiatives in fostering appropriate use of OTC CHM, vitamins, and minerals. Engaging community pharmacists in guiding safe and effective use of OTC CHM amongst the uninsured is essential given their low accessibility to CHC services. Prescription of Taiji instead of physical exercises to women and older people could be more culturally appropriate, and the possibility of including this as part of the CHC services worth further exploration.

  11. Microstructural and surface property variations due to the amorphous region formed by thermal annealing in Al-doped ZnO thin films grown on n-Si (1 0 0) substrates

    International Nuclear Information System (INIS)

    X-ray diffraction (XRD) patterns revealed that the as-grown and annealed Al-doped ZnO (AZO) films grown on the n-Si (1 0 0) substrates were polycrystalline. Transmission electron microscopy (TEM) images showed that bright-contrast regions existed in the grain boundary, and high-resolution TEM (HRTEM) images showed that the bright-contrast regions with an amorphous phase were embedded in the ZnO grains. While the surface roughness of the AZO film annealed at 800 deg. C became smoother, those of the AZO films annealed at 900 and 1000 deg. C became rougher. XRD patterns, TEM images, selected-area electron diffraction patterns, HRTEM images, and atomic force microscopy (AFM) images showed that the crystallinity in the AZO thin films grown on the n-Si (1 0 0) substrates was enhanced resulting from the release in the strain energy for the AZO thin films due to thermal annealing at 800 deg. C. XRD patterns and AFM images show that the crystallinity of the AZO thin films annealed at 1000 deg. C deteriorated due to the formation of the amorphous phase in the ZnO thin films.

Moreover, EEG theta frequency activity is quite different in these groups. This study investigated the correlation between biomarkers and memory performance.Methods: EEG α3/α2 power ratio and cortical thickness were computed in 74 adult subjects with prodromal Alzheimer’s disease. Twenty of these subjects also underwent assessment of blood perfusion by single-photon emission computed tomography (SPECT. Pearson’s r was used to assess the correlation between cortical thinning, brain perfusion, and memory impairment.Results: In the higher α3/α2 frequency power ratio group, greater cortical atrophy and lower regional perfusion in the temporoparietal cortex was correlated with an increase in EEG theta frequency. Memory impairment was more pronounced in the magnetic resonance imaging group and SPECT groups.Conclusion: A high EEG upper/low alpha power ratio was associated with cortical thinning and less perfusion in the temporoparietal area. Moreover, atrophy and less regional perfusion were significantly correlated with memory impairment in subjects with prodromal Alzheimer’s disease. The EEG upper/lower alpha frequency power ratio could be useful for identifying individuals at risk for progression to Alzheimer’s dementia and may be of value in the clinical context.Keywords: electroencephalography, perfusion, atrophy, temporoparietal network, memory deficits, hippocampal volume, mild cognitive impairment, Alzheimer’s disease

    Full Text Available Abstract Background In China, high prevalence of HBV and HCV parallels with the growing epidemic of syphilis and HIV in the general population poses a great threat to blood safety. This study investigated the prevalence of serologic markers for transfusion transmissible infections (TTIs among four Chinese blood centers. Methods We examined whole blood donations collected from January 2000 through December 2010 at four Chinese blood centers. Post-donation testing of TTIs (HIV, HBV, HCV and syphilis were conducted using two different enzyme-linked immunosorbent assay kits for each seromarker. The prevalence of serologic markers for TTIs (% was calculated and additional analysis was conducted to examine donor characteristics associated with positive TTIs serology. Results Of the 4,366,283 donations, 60% were from first-time donors and 40% were from repeated donors. The overall prevalence of HIV, HBsAg, HCV and syphilis was 0.08%, 0.86%, 0.51% and 0.47%, respectively. The prevalence profile of TTIs varied among different blood centers and appeared at relatively high levels. Overall, the prevalence of HBsAg and HCV demonstrated a decline trend among four blood centers, while the prevalence of HIV and syphilis displayed three different trends: constantly steady, continually increasing and declining among different centers. Conclusions This study reflects the risk of TTIs has been greatly reduced in China, but blood transfusion remains an ongoing risk factor for the spread of blood-borne infections, and further work and improvements are needed to strengthen both safety and availability of blood in China.

    Detailed radio observations of the Sagittarius A complex are presented and discussed. The evidence is consistent with a large-scale poloidal magnetic field lying at the Galactic center. Arguments are made in favor of the suggestion that ionized gas is flowing out isotropically from the nucleus, and that Sgr A East is located behind Sgr A West. The question whether Sgr East is a supernova remnant or the result of energetic activity related to the Galactic nucleus is addressed. 126 references.

    Based on empirical evidence from a free word order language (German) we propose a fundamental revision of the principles guiding the ordering of discourse entities in the forward-looking centers within the centering model. We claim that grammatical role criteria should be replaced by indicators of the functional information structure of the utterances, i.e., the distinction between context-bound and unbound discourse elements. This claim is backed up by an empirical evaluation of functional centering.

    PurposeTo compare clinical and urodynamic results of transurethral resection of the prostate (TURP) to original and PErFecTED prostate artery embolization (PAE) methods for benign prostatic hyperplasia.MethodsWe prospectively randomized 30 patients to receive TURP or original PAE (oPAE) and compared them to a cohort of patients treated by PErFecTED PAE, with a minimum of 1-year follow-up. Patients were assessed for urodynamic parameters, prostate volume, international prostate symptom score (IPSS), and quality of life (QoL).ResultsAll groups were comparable for all pre-treatment parameters except bladder contractility and peak urine flow rate (Q{sub max}), both of which were significantly better in the TURP group, and IIEF score, which was significantly higher among PErFecTED PAE patients than TURP patients. All groups experienced significant improvement in IPSS, QoL, prostate volume, and Q{sub max}. TURP and PErFecTED PAE both resulted in significantly lower IPSS than oPAE but were not significantly different from one another. TURP resulted in significantly higher Q{sub max} and significantly smaller prostate volume than either original or PErFecTED PAE but required spinal anesthesia and hospitalization. Two patients in the oPAE group with hypocontractile bladders experienced recurrence of symptoms and were treated with TURP. In the TURP group, urinary incontinence occurred in 4/15 patients (26.7 %), rupture of the prostatic capsule in 1/15 (6.7 %), retrograde ejaculation in all patients (100 %), and one patient was readmitted for temporary bladder irrigation due to hematuria.ConclusionsTURP and PAE are both safe and effective treatments. TURP and PErFecTED PAE yield similar symptom improvement, but TURP is associated with both better urodynamic results and more adverse events.

  12. Measures of gamma rays between 0,3 MeV and 3,0 MeV and of the 0,511 MeV annihilation line coming from Galactic Center Region

    International Nuclear Information System (INIS)

    The detection of the flux of the electron-positron annihilation line coming from the Galactic Center direction allows one to estimate the rate of positrons production and the corresponding luminosity. The results of measurements of the annihilation line flux intensity at 0.511 MeV, obtained with a balloon borne experiment to measure gamma rays in the energy interval 0.3 to 3 MeV are presented. The detector looked at the galactic disk in the longitude interval -310 0 and observed a flux intensity of (6.70 +- 0.85) x 10-3 photons cm-2 s-1, which is in good agreement with the flux value estimated assuming that the Galactic Center is a line source emitting uniformly. Some likely sources of positrons and annhilation regions are also discussed. The results for the continuum spectrum emitted from the Galactic Center in the energy interval 0.3 to 0.67 MeV are presented and compared with measurements had already made. (Author)

    We present a study of star formation in the Central Molecular Zone (CMZ) of our Galaxy through the association of three star formation indicators: 6.7 GHz CH3OH masers, 22 GHz H2O masers, and enhanced 4.5 micron emission (`green') sources. We explore how star formation in the Galactic center (l < 1.3 deg, |b| < 10', where l and b are Galactic longitude and Galactic latitude) compares with that of the Galactic disk (6 deg < l < 345 deg, |b| < 2 deg). Using an automated algorithm, we search for enhanced 4.5 micron emission sources toward 6.7 GHz CH3OH masers detected in the Parkes Methanol Multibeam Survey. We combine these results with our 22 GHz H2O maser survey of the CMZ carried out with the Mopra telescope. We find that the correlation of CH3OH masers with green sources is a function of Galactic latitude, with a minimum close to b=0 and increasing with |b| (toward the central part of the Galaxy, 6 deg < l < 345 deg, |b| < 2 deg). We find no significant difference between the correla...

    We present the first sub-arcminute images of the Galactic Center above 10 keV, obtained with NuSTAR. NuSTAR resolves the hard X-ray source IGR J17456-2901 into non-thermal X-ray filaments, molecular clouds, point sources and a previously unknown central component of hard X-ray emission (CHXE). NuSTAR detects four non-thermal X-ray filaments, extending the detection of their power-law spectra with $\\Gamma\\sim1.3$-$2.3$ up to ~50 keV. A morphological and spectral study of the filaments suggests that their origin may be heterogeneous, where previous studies suggested a common origin in young pulsar wind nebulae (PWNe).

    The report answers the question where, why and how different climate variables have changed within the last 100 years. The analyzed variables are observed time series of temperature (mean, maximum, minimum), precipitation, air pressure, and water vapour pressure in a monthly resolution. The time series are given as station data and grid box data as well. Two kinds of time-series analysis are performed. The first is applied to find significant changes concerning mean and variance of the time series. Thereby also changes in the annual cycle and frequency of extreme events arise. The second approach is used to detect significant spatio-temporal patterns in the variations of climate variables, which are most likely driven by known natural and anthropogenic climate forcings. Furtheron, an estimation of climate noise allows to indicate regions where certain climate variables have changed significantly due to the enhanced anthropogenic greenhouse effect. (orig.) [German] Der Bericht gibt Antwort auf die Frage, wo sich welche Klimavariable wie und warum veraendert hat. Ausgangspunkt der Analyse sind huntertjaehrige Zeitreihen der Temperatur (Mittel, Maximum, Minimum), des Niederschlags, Luftdrucks und Wasserdampfpartialdrucks in monatlicher Aufloesung. Es wurden sowohl Stationsdaten als auch Gitterpunktdaten verwendet. Mit Hilfe der strukturorientierten Zeitreihenzerlegung wurden signifikankte Aenderungen im Mittel und in der Varianz der Zeitreihen gefunden. Diese betreffen auch Aenderungen im Jahresgang und in der Haeufigkeit extremer Ereignisse. Die ursachenorientierte Zeitreihenzerlegung selektiert signifikante raumzeitliche Variationen der Klimavariablen, die natuerlichen bzw. anthropogenen Klimaantrieben zugeordnet werden koennen.

  16. Anatomy-based reconstruction of FDG-PET images with implicit partial volume correction improves detection of hypometabolic regions in patients with epilepsy due to focal cortical dysplasia diagnosed on MRI

    International Nuclear Information System (INIS)

    Detection of hypometabolic areas on interictal FDG-PET images for assessing the epileptogenic zone is hampered by partial volume effects. We evaluated the performance of an anatomy-based maximum a-posteriori (A-MAP) reconstruction algorithm which combined noise suppression with correction for the partial volume effect in the detection of hypometabolic areas in patients with focal cortical dysplasia (FCD). FDG-PET images from 14 patients with refractory partial epilepsy were reconstructed using A-MAP and maximum likelihood (ML) reconstruction. In all patients, presurgical evaluation showed that FCD represented the epileptic lesion. Correspondence between the FCD location and regional metabolism on a predefined atlas was evaluated. An asymmetry index of FCD to normal cortex was calculated. Hypometabolism at the FCD location was detected in 9/14 patients (64%) using ML and in 10/14 patients (71%) using A-MAP reconstruction. Hypometabolic areas outside the FCD location were detected in 12/14 patients (86%) using ML and in 11/14 patients (79%) using A-MAP reconstruction. The asymmetry index was higher using A-MAP reconstruction (0.61, ML 0.49, p=0.03). The A-MAP reconstruction algorithm improved visual detection of epileptic FCD on brain FDG-PET images compared to ML reconstruction, due to higher contrast and better delineation of the lesion. This improvement failed to reach significance in our small sample. Hypometabolism outside the lesion is often present, consistent with the observation that the functional deficit zone tends to be larger than the epileptogenic zone. (orig.)

    Full Text Available Pneumoconioses make up a group of lung diseases related to exposure to mineral dusts in work environments. They represent a public health problem, considering that such diseases could already have been eradicated from Brazil, if control measures had been taken in such environments. The aim of this research was to map the distribution of deaths due to pneumoconioses in the different geographical areas and states of Brazil, by means of an ecological survey carried out in the working population older than 15 years. The preliminary results of this investigation in the Brazilian macro-regions from 1979 to 1998 are presented. This study used mortality data provided by the Mortality Information System of Datasus - Data Processing Department of the Unified Health System, using the codes of the ICD (International Classification of Diseases 9 and ICD 10. The results showed an increase in the mortality coefficient due to pneumoconioses per 1 million inhabitants per year along the studied period of time. By shifting from ICD 9 to ICD 10, the frequency of deaths doubled. We concluded that the mortality coefficients due to pneumoconioses do not reflect the problem properly, thus masking the transcendence and magnitude of the disease. In order to obtain more representative indicators, the actually exposed population and the territorial distribution of the disease have to be known.As pneumoconioses representam um conjunto de doenças pulmonares relacionadas à exposição às poeiras minerais nos ambientes de trabalho. Constituem um problema de saúde pública, visto que poderia ser uma doença já erradicada em nosso meio com o uso de medidas de controle nesses ambientes.

    Full Text Available Background: Blood transfusion carries the risk of transmission of several infectious agents. The latest method for blood screening, nucleic acid testing is not affordable in developing countries. Aim: The study was aimed to find response to post-donation counseling for reactive markers among the voluntary blood donors donating in blood donation camps. Material and Methods: This 1 year study was conducted in 2011. Transfusion transmitted infections testing was performed by routine enzyme linked immunosorbent assay method. The initial human immunodeficiency virus (HIV reactive donors who returned back to the blood bank were confidentially counseled and referred to the Integrated Counseling Cum Testing Center (ICTC. The hepatitis B surface antigen (HBsAg and anti-hepatitis C virus (HCV reactive donors were referred to the gastroenterology department for confirmation by qualitative polymerase chain reaction (PCR, Roche Diagnostics, Germany and followed-up. Results: Twenty seven thousand two hundred forty six 27,246 units were collected during the survey. One hundred twenty nine129 units were reactive for HIV 1 and 2, 99 were reactive for HCV, 206 for hepatitis B virus (HBV. Of these reactive donors, 138 could be personally communicated. Out of 47, 27 donors who returned for counseling were initially reactive for HIV 1 and 2, 8 for HBsAg and 12 for anti-HCV. Two were positive for HBV deoxyribonucleic acid and one was positive for HCV ribonucleic acid. The HIV positivity was detected in 1 of 27 donors at ICTC. Conclusion: The response to the post-donation counseling appears in this study to be only 34% (47/138, which is still a challenge.

METHODS: The limnological/water quality study was carried out in rainy (March/2007 and dry (September/2007 seasons, considering 17 sampling stations. RESULTS: Variables such as channel width and depth, water velocity and temperature increased towards the river's mouth; water transparency, velocity and dissolved oxygen were higher in the upstream regions. Light penetration was total at most sampling stations and pH was predominantly acid. The sampling stations impacted by pollution sources, Lavapés and Araquá Rivers, exhibited higher values of electric conductivity, suspended solids, total nitrogen, nitrate, nitrite, ammonium, total dissolved phosphorus, BOD, and thermotolerant coliforms. Higher values of electric conductivity, turbidity and suspended solids were observed in the rainy season, whereas higher chlorophyll concentrations occurred in the dry season. The Lavapés River exhibits the worst environmental condition, while Capivara River is under better state of conservation. This study shows that it is urgent the implementation of measures for preservation and restoration of these regional aquatic ecosystems. All studied rivers were influenced by seasonal variation, sewage discharges and by watershed use and occupation. The TSI is a good analysis tool. The studied rivers export organic matter and TN, TP and SS loads to Tietê and Paranapanema rivers. CONCLUSIONS: This study show the importance of river management and that the accelerated degradation of the river systems indicates the little progress of the Brazilian legislation in terms of preservation and good management practices and that the interface between science, law, management and conservation need to be improved.

  7. The STAR concept: A hierarchical hub-spoke nuclear architecture based on long refuelling interval battery reactors and regional fuel cycle centers

    International Nuclear Information System (INIS)

    The STAR reactor and fuel cycle concept is devised to attain Gen-IV goals by responding to foreseen mid century needs and market conditions. It is targeted to fill energy and potable water needs for urban centres in developing countries and is designed to fit within a hierarchical hub-spoke energy architecture based on regional fuel cycle centres, using nuclear fuel as the long distance energy carrier - with distributed electricity generation as the local carrier to mesh with existing urban energy distribution infrastructures using grid delivery of electricity, potable water, and communications (and sewage return) through a common grid of easements. STAR is also intended for Independent Power Producers in industrialized countries seeking to service emerging markets for hydrogen and water production. STAR concept development is being conducted for a portfolio of specific reactor and balance of plant designs to enable an incremental market penetration that is time-phased according to the degree of R and D required. STAR-LM is a Pb-cooled, 400 MWth, natural circulation reactor of 565 deg. C core outlet temperature driving a supercritical CO2 Brayton cycle for electricity production. It draws on many proven technologies and will be ready for market in 15-20 years. STAR-H2 raises the Pb outlet temperature to 800 deg. C to drive a thermochemical water cracking cycle and will require additional R and D. SSTAR takes the STAR-LM design features down to ∼25 to 50 MWth for secure energy supply to remote small villages. All STAR concepts are designed for 20-year refuelling interval and rely on out-sourcing fuel cycle and waste management services to proposed regional fuel cycle centres. All employ desalination (or alterative) bottoming cycles to extend their scope of energy services and to minimize their environmental footprint. (author)

    Recent palynological investigations carried out in the eastern Gulf of Cadiz (MD99-2339 core) over MIS 3 enable to consider dinoflagellate cyst assemblage patterns over the last 50 ka BP through a compilation of 6 cores from the NE subtropical Atlantic to the Northern Bay of Biscay (also including cores MD95-2042, MD95-2043, MD04-2805CQ, VK03-58bis). Dinocyst signals depict hydrological front latitudinal shifts over the last glacial and associated sea-surface consequences regarding past regimes of primary productivity. We show here new data clearly evidencing subtropical latitudes of Cadiz as being as productive areas over the last glacial as recorded today in the septentrional part of the Bay of Biscay, especially between GI 8 and GI 12. We especially focus on dinocyst-species Lingulodinium machaerophorum relative abundances and absolute concentrations that we first evidence as a powerful tool to reconstruct and discuss productivity shifts through time in the temperate North Atlantic. This spatio-temporal synthesis bring important evidences of fast migrating paleoproductiviy centers from the last glacial period to present, implying also large consequences on the biological pump through time. Regarding this specific session, 5 of the 6 cores discussed here were retrieved by the R/V Marion Dufresne through 3 different cruises: Core MD99-2339 (35.89°N, 7.53°W, 1170m water depth, 18.54m long) was retrieved in a contouritic field in the oriental part of the Gulf of Cadiz by the oceanographic R/V Marion Dufresne during the 1999 International Marine Global Change Studies V (IMAGES V) cruise (Labeyrie, Jansen and Cortijo, 2003). Cores MD95-2042 (37°48'N, 10°10'W, 3146m water depth, 39.56m long) and MD95-2043 (36°8.6'N, 2°37.3'W, 1841m water depth, 36m long) were retrieved from the SW Iberian margin and the central Alboran Sea, respectively, by the oceanographic R/V Marion Dufresne during the 1995 IMAGES I cruise (Bassinot and Labeyrie, 1996).

    Full Text Available Objective: The objective of this study was to verify the evolution of pregnancies in sickle cell patients followed at one institution over a period of 12 years (January 2000 to June 2012. Methods: The study evaluated 34 pregnant women with sickle cell disease with a mean age of 23.9 ± 5.3 years. The incidence of obstetric complications, non-obstetric complications linked to sickle cell disease and complications in the newborn were analyzed. Results: A total of 26% of the cases reported previous miscarriages, 20% had preterm labor, 10% had pre-eclampsia, and 5% had gestational diabetes. Forty-one percent of the deliveries were cesarean sections and 29% of patients required blood transfusions. In respect to sickle cell disease, 62% of patients had vaso-occlusive crises, 29% had acute chest syndrome, 23% had urinary tract infection, 15% had impaired cardiac function and 6% developed pulmonary hypertension. Only one patient died in the postnatal period due to acute chest syndrome. The mean gestational age was 37.8 ± 2.63 weeks, and mean newborn weight was 2.809 ± 643.8 g. There were seven fetal losses, including three stillbirths and four miscarriages. The impact of transfusion therapy on the incidence of maternal–fetal complications during pregnancy was evaluated. Conclusions: Pregnancy in sickle cell patients is still associated with complications. Although no statistical difference was observed between transfused and non-transfused women, there were no deaths (fetal or maternal in transfused patients whereas one maternal death and three stillbirths occurred in non-transfused women. A larger study of sickle cell pregnant women will be necessary to elucidate the actual role of transfusion during pregnancy in sickle cell disease.

  19. Study of the electron-positron annihilation in the galactic center region with the Integral/SPI spectrometer; Etude de l'annihilation electron-positon dans la region du centre galactique avec le spectrometre INTEGRAL/SPI

    2007-04-15

    A spectral feature was detected in 1970 in the gamma-ray emission from the central regions of the Milky Way, during balloon flight observations. Located near 511 keV, this feature was soon attributed to the gamma-ray line tracing the annihilation of electrons with their anti-particles, positrons. However, none of the multiple astrophysical scenarios contemplated to explain the production of positrons in the Galactic bulge has been able to reproduce the high injection rate deduced from the flux of the 511 keV line, close to 10{sup 43} positrons per second. Launched in 2002, the European gamma-ray satellite INTEGRAL was provided with a spectrometer, SPI, whose unprecedented imaging and spectral capabilities in this energy range enable us to further study the source of the 511 keV line detected in the Galactic centre region. Indeed, a better determination of the spatial extent of the source, the intrinsic width of the line and the fraction of positrons annihilating in-flight, directly or via the formation of ortho-Positronium atoms would improve our knowledge of both the annihilation medium and the initial source of positrons, and could allow us to discriminate between the various explanatory scenarios. The first part of this thesis deals with a key ingredient in the extraction of the annihilation spectrum: the optimization of the instrumental background model. New data screening and tracer selection procedures are presented. Classical multi-linear models are compared to neural and Bayesian networks. Finally, three years of observation are used to constrain the width of the source and derive its spectrum. The second part of the thesis focuses on one of the possible scenarios explaining the high positron injection rate deduced from the flux of the 511 keV line: the annihilation of light dark matter particles into electron-positron pairs. The various radiation mechanisms involved are modeled and confronted to observations in order to set an upper limit on the injection

  20. The Lathrop Wells volcanic center

    International Nuclear Information System (INIS)

    The Lathrop Wells volcanic center is located 20 km south of the potential Yucca Mountain site, at the south end of the Yucca Mountain range. This paper discusses a detailed Study Plan which was prepared describing planned geochronology and field studies to assess the chronology of the Lathrop Wells volcanic center and other Quaternary volcanic centers in the region. A paper was published discussing the geomorphic and soil evidence for a late Pleistocene or Holoceno age for the main cone of the center. The purpose of this paper was to expose the ideas concerning the age of the Lathrop Wells center to scientific scrutiny. Additionally, field evidence was described suggesting the Lathrop Wells center may have formed from multiple eruptive events with significant intervals of no activity between events. This interpretation breaks with established convention in the volcanological literature that small volume basalt centers are monogenetic

    Quadtree-like pyramids have the advantage of resulting in a multiresolution representation where each pyramid node has four unambiguous parents. Such a centered topology guarantees a clearly defined up-projection of labels. This concept has been successfully and extensively used in applications of contour detection, object recognition and segmentation. Unfortunately, the quadtree-like type of pyramid has poor approximation powers because of the employed piecewise-constant image model. This pa...

    Due to its extraordinarily high concentration of known relativistic particle accelerators such as pulsar wind nebula, supernova remnants, dense molecular cloud regions, and the supermassive black hole (Sgr A*); the center of the Milky Way galaxy has long been an ideal target for high energy (HE, 0.1-100 GeV) and very high energy ( VHE, 50 GeV-50 TeV) gamma-ray emission. Indeed, detections of Sgr A* and other nearby regions of gamma-ray emission have been reported by EGRET and Fermi-LAT in the HE band, as well as CANGAROO, Whipple, HESS, VERITAS, and MAGIC in the VHE band. Here we report on the results of extended observations of the region with VERITAS between 2010-2014. Due to the visibility of the source for VERITAS in the Northern Hemisphere, these observations provide the most sensitive probe of gamma-ray emission above 2 TeV in one of the most complicated and interesting regions of our home galaxy.

  13. Determination of rare earth elements, thorium and uranium by inductively coupled plasma mass spectrometry and strontium isotopes by thermal ionization mass spectrometry in soil samples of Bryansk region contaminated due to Chernobyl accident

    International Nuclear Information System (INIS)

    Inductively coupled plasma mass spectrometric (ICP-MS) determination of rare earth elements (REEs), thorium and uranium in forest, pasture, field and kitchen garden soils from a Russian territory and in certified reference materials (JLK-1, JSD-2 and BCR-1) is described. In addition to concentration data, strontium isotopic composition of the soil samples were measured by thermal ionization mass spectrometry. The measurements contributed to the understanding of the background levels of these elements in an area contaminated due to Chernobyl accident. There was not a significant variation in the concentration of REEs at different depth levels in forest soil samples, however, the ratio of Th/U varied from 3.32 to 3.60. Though concentration of U and Th varied to some extent, the ratio did not show much variation. The value of 87Sr/86Sr ratio, was in the top layer soil sample relatively higher than in the lower layers. (author)

  14. Human due diligence.

    Science.gov (United States)

    Harding, David; Rouse, Ted

    2007-04-01

    Most companies do a thorough job of financial due diligence when they acquire other companies. But all too often, deal makers simply ignore or underestimate the significance of people issues in mergers and acquisitions. The consequences are severe. Most obviously, there's a high degree of talent loss after a deal's announcement. To make matters worse, differences in decision-making styles lead to infighting; integration stalls; and productivity declines. The good news is that human due diligence can help companies avoid these problems. Done early enough, it helps acquirers decide whether to embrace or kill a deal and determine the price they are willing to pay. It also lays the groundwork for smooth integration. When acquirers have done their homework, they can uncover capability gaps, points of friction, and differences in decision making. Even more important, they can make the critical "people" decisions-who stays, who goes, who runs the combined business, what to do with the rank and file-at the time the deal is announced or shortly thereafter. Making such decisions within the first 30 days is critical to the success of a deal. Hostile situations clearly make things more difficult, but companies can and must still do a certain amount of human due diligence to reduce the inevitable fallout from the acquisition process and smooth the integration. This article details the steps involved in conducting human due diligence. The approach is structured around answering five basic questions: Who is the cultural acquirer? What kind of organization do you want? Will the two cultures mesh? Who are the people you most want to retain? And how will rank-and-file employees react to the deal? Unless an acquiring company has answered these questions to its satisfaction, the acquisition it is making will be very likely to end badly. PMID:17432159

    2012-05-01

    The historical interplay between societies is governed by many factors, including in particular the spreading of languages, religion, and other symbolic traits. Cultural development, in turn, is coupled to the emergence and maintenance of information spreading. Strong centralized cultures exist due to attention from their members, whose faithfulness in turn relies on the supply of information. Here we discuss a culture evolution model on a planar geometry that takes into account aspects of the feedback between information spreading and its maintenance. Features of the model are highlighted by comparing it to cultural spreading in ancient and medieval Europe, where it suggests in particular that long-lived centers should be located in geographically remote regions.

    Full Text Available Quando se buscam, em literatura, dados sobre a irrigação no Brasil, o que se encontra disponível é a área irrigada por estado e por método de irrigação. A distribuição dentro dos estados, o número de equipamentos e seu tamanho são de difícil obtenção, mesmo junto às indústrias. No entanto, essas são informações fundamentais quando se pretende estudar a disponibilidade hídrica ou o potencial de crescimento da área irrigada de uma região, por exemplo, temas esses bastante atuais com a crescente demanda por água potável em nível mundial e nacional. Com o presente trabalho objetivou-se coletar essas informações utilizando-se de imagens do satélite Landsat com base na característica intrínseca do sistema de pivô central de marcar com um círculo o local onde está instalado. Em função do referenciamento cartesiano das imagens e da sua articulação com os mapas do IBGE, foi possível desenhar os mapas estaduais com as áreas de concentração desse tipo de equipamento que, quando comparados com outras fontes, permitiram concluir-se pela validade da metodologia para obtenção dessas informações.Irrigated areas by state and by irrigation method is the available information about irrigation in Brazil. Distribution inside the states, number or size is not easily found even through the industry. These data are very important when one intends to study water availability or growth potencial of irrigated areas for a specific site due to the increasing concern about drinking water worldwide and nationally. The present study had the objective to collect such information using satellite images from Landsat based on the intrinsic characteristic of the center pivot equipments, the circular mark on landscape easily visible.

The Excel based tool incorporates hourly climate based building loads data to arrive at the composite energy demand for the district and compares the Net Present Value (NPV) of the costs of CHP/DE alternatives. This tool has been used to provide assistance to several projects in the Northeast, Mid-Atlantic, Intermountain and Pacific Regions. The tool was disseminated to the CEACs and supplemented by a Training Webinar and a How to Guide IDEA produced a US Community Energy Development Guide to support mayors, planners, community leaders, real estate developers and economic development officials who are interested in planning more sustainable urban energy infrastructure, creating community energy master plans and implementing CHP/ District Energy systems in cities, communities and towns. IDEA has collected industry data and provided a comprehensive data set containing information on District Energy installations in the US. District energy systems are present in 49 states and the District of Columbia. Of the 597 systems 55% were DE alone while the remainder was some combination of CHP, district heating, and district cooling. District energy systems that do not currently involve electric generation are strong near-term candidates for the adoption of CHP due to the magnitude of their aggregated thermal load. This data has helped inform specific and targeted initiatives including technical assistance provided by the CEAC’s for EPA’s Boiler MACT Compliance by large District Heating System boilers. These outcomes have been greatly enabled by the close coordination and collaboration with DOE CEAC leadership and with the eight regional US DOE Clean Energy Application Centers and the award’s incremental funding has allowed IDEA to leverage our resources to be an effective champion for Clean Energy.

    The Strategic Defense Initiative Organization has created data centers for midcourse, plumes, and backgrounds phenomenologies. The Backgrounds Data Center (BDC) has been designated as the prime archive for data collected by SDIO programs. The BDC maintains a Summary Catalog that contains 'metadata,' that is, information about data, such as when the data were obtained, what the spectral range of the data is, and what region of the Earth or sky was observed. Queries to this catalog result in a listing of all data sets (from all experiments in the Summary Catalog) that satisfy the specified criteria. Thus, the user can identify different experiments that made similar observations and order them from the BDC for analysis. On-site users can use the Science Analysis Facility (SAFE for this purpose. For some programs, the BDC maintains a Program Catalog, which can classify data in as many ways as desired (rather than just by position, time, and spectral range as in the Summary Catalog). For example, data sets could be tagged with such diverse parameters as solar illumination angle, signal level, or the value of a particular spectral ratio, as long as these quantities can be read from the digital record or calculated from it by the ingest program. All unclassified catalogs and unclassified data will be remotely accessible.

    The Mid Atlantic Clean Energy Application Center (MACEAC), managed by The Penn State College of Engineering, serves the six states in the Mid-Atlantic region (Pennsylvania, New Jersey, Delaware, Maryland, Virginia and West Virginia) plus the District of Columbia. The goals of the Mid-Atlantic CEAC are to promote the adoption of Combined Heat and Power (CHP), Waste Heat Recovery (WHR) and District Energy Systems (DES) in the Mid Atlantic area through education and technical support to more than 1,200 regional industry and government representatives in the region. The successful promotion of these technologies by the MACEAC was accomplished through the following efforts; (1)The MACEAC developed a series of technology transfer networks with State energy and environmental offices, Association of Energy Engineers local chapters, local community development organizations, utilities and, Penn State Department of Architectural Engineering alumni and their firms to effectively educate local practitioners about the energy utilization, environmental and economic advantages of CHP, WHR and DES; (2) Completed assessments of the regional technical and market potential for CHP, WHR and DE technologies application in the context of state specific energy prices, state energy and efficiency portfolio development. The studies were completed for Pennsylvania, New Jersey and Maryland and included a set of incentive adoption probability models used as a to guide during implementation discussions with State energy policy makers; (3) Using the technical and market assessments and adoption incentive models, the Mid Atlantic CEAC developed regional strategic action plans for the promotion of CHP Application technology for Pennsylvania, New Jersey and Maryland; (4) The CHP market assessment and incentive adoption model information was discussed, on a continuing basis, with relevant state agencies, policy makers and Public Utility Commission organizations resulting in CHP favorable incentive

  9. Rapid guiding center calculations

    International Nuclear Information System (INIS)

    Premature loss of high energy particles, and in particular fusion alpha particles, is very deleterious in a fusion reactor. Because of this it is necessary to make long-time simulations, on the order of the alpha particle slowing down time, with a number of test particles sufficient to give predictions with reasonable statistical accuracy. Furthermore it is desirable to do this for a large number of equilibria with different characteristic magnetic field ripple, to best optimize engineering designs. In addition, modification of the particle distribution due to magnetohydrodynamic (MHD) modes such as the saw tooth mode present in the plasma can be important, and this effect requires additional simulation. Thus the large number of necessary simulations means any increase of computing speed in guiding center codes is an important improvement in predictive capability. Previous guiding center codes using numerical equilibria such as ORBIT evaluated the local field strength and ripple magnitude using Lagrangian interpolation on a grid. Evaluation of these quantities four times per time step (using a fourth order Runge-Kutta routine) constitutes the major computational effort of the code. In the present work the authors represent the field quantities through an expansion in terms of pseudo-cartesian coordinates formed from the magnetic coordinates. The simplicity of the representation gives four important advantages over previous methods

    Agile development methods began to emerge around 20 years ago. However, it was not until the early 2000s that they began to be widely used in industry. This growth was often due to the advent of Internet services requiring faster cycles of development in order to heighten the rate at which an ever-greater number of functionalities were made available. In parallel, user-centered design (UCD) methods were also becoming more and more widely used: hence, user-centered design and agile methods were bound to cross paths, at least in the telecoms industry!

  20. Laser profile changes due to photon–axion induced beam splitting

    International Nuclear Information System (INIS)

    This paper looks at a potentially unique measurable due to photon–axion coupling in an external magnetic field. Traditionally, detection of such a coupling has focused on observation of an optical rotation of the beam's polarization due to either a birefringence or a path length difference (p.l.d.) between two polarization states. Such experiments, utilizing mirror cavities, have been significantly limited in sensitivity; approaching coupling strengths of ∼ga=10−7 GeV−1. Here the bifurcation of a beam in a cavity is explored along with the possibility of measuring its influence on the photon density. Simulations indicate that coupling to levels ga∼10–12 are, with an appropriate choice of cavity, within measurable limits. This is due to a rapid growth of a signal defined by the energy loss from the center accompanying an increase in the region beyond the beam waist. Finally, the influence of a non-zero axion mass is explored

  4. Cold dust in hot regions

    International Nuclear Information System (INIS)

    We mapped five massive star-forming regions with the SCUBA-2 camera on the James Clerk Maxwell Telescope. Temperature and column density maps are obtained from the SCUBA-2 450 and 850 μm images. Most of the dense clumps we find have central temperatures below 20 K, with some as cold as 8 K, suggesting that they have no internal heating due to the presence of embedded protostars. This is surprising, because at the high densities inferred from these images and at these low temperatures such clumps should be unstable, collapsing to form stars and generating internal heating. The column densities at the clump centers exceed 1023 cm–2, and the derived peak visual extinction values are from 25 to 500 mag for β = 1.5-2.5, indicating highly opaque centers. The observed cloud gas masses range from ∼10 to 103 M ☉. The outer regions of the clumps follow an r –2.36±0.35 density distribution, and this power-law structure is observed outside of typically 104 AU. All these findings suggest that these clumps are high-mass starless clumps and most likely contain high-mass starless cores.

  12. Worldwide electricity used in data centers

    International Nuclear Information System (INIS)

    The direct electricity used by data centers has become an important issue in recent years as demands for new Internet services (such as search, music downloads, video-on-demand, social networking, and telephony) have become more widespread. This study estimates historical electricity used by data centers worldwide and regionally on the basis of more detailed data than were available for previous assessments, including electricity used by servers, data center communications, and storage equipment. Aggregate electricity use for data centers doubled worldwide from 2000 to 2005. Three quarters of this growth was the result of growth in the number of the least expensive (volume) servers. Data center communications and storage equipment each contributed about 10% of the growth. Total electricity use grew at an average annual rate of 16.7% per year, with the Asia Pacific region (without Japan) being the only major world region with growth significantly exceeding that average. Direct electricity used by information technology equipment in data centers represented about 0.5% of total world electricity consumption in 2005. When electricity for cooling and power distribution is included, that figure is about 1%. Worldwide data center power demand in 2005 was equivalent (in capacity terms) to about seventeen 1000 MW power plants.

  15. Dark Matter Annihilation at the Galactic Center

    Energy Technology Data Exchange (ETDEWEB)

    Linden, Timothy Ryan [Univ. of California, Santa Cruz, CA (United States)

    2013-06-01

    Observations by the WMAP and PLANCK satellites have provided extraordinarily accurate observations on the densities of baryonic matter, dark matter, and dark energy in the universe. These observations indicate that our universe is composed of approximately ve times as much dark matter as baryonic matter. However, e orts to detect a particle responsible for the energy density of dark matter have been unsuccessful. Theoretical models have indicated that a leading candidate for the dark matter is the lightest supersymmetric particle, which may be stable due to a conserved R-parity. This dark matter particle would still be capable of interacting with baryons via weak-force interactions in the early universe, a process which was found to naturally explain the observed relic abundance of dark matter today. These residual annihilations can persist, albeit at a much lower rate, in the present universe, providing a detectable signal from dark matter annihilation events which occur throughout the universe. Simulations calculating the distribution of dark matter in our galaxy almost universally predict the galactic center of the Milky Way Galaxy (GC) to provide the brightest signal from dark matter annihilation due to its relative proximity and large simulated dark matter density. Recent advances in telescope technology have allowed for the rst multiwavelength analysis of the GC, with suitable e ective exposure, angular resolution, and energy resolution in order to detect dark matter particles with properties similar to those predicted by the WIMP miracle. In this work, I describe ongoing e orts which have successfully detected an excess in -ray emission from the region immediately surrounding the GC, which is di cult to describe in terms of standard di use emission predicted in the GC region. While the jury is still out on any dark matter interpretation of this excess, I describe several related observations which may indicate a dark matter origin. Finally, I discuss the

    The damping coefficient of capillary waves due to the evaporation-condensation process at the interface of the two phases of a fluid is evaluated. To highlight the mechanism of the effect of heat and mass transfer across the interface between regions of liquid and vapor, potential flow of incompressible fluids are assumed. Thus other mechanisms of damping are neglected. To fascilitate the analysis, the method of multiple-scale is employed in the analysis, even though the problem is linear.

    The Department of Interior Northeast Climate Science Center (NE CSC) is part of a federal network of eight Climate Science Centers created to provide scientific information, tools, and techniques that managers and other parties interested in land, water, wildlife and cultural resources can use to anticipate, monitor, and adapt to climate change. Recognizing the critical threats, unique climate challenges, and expansive and diverse nature of the northeast region, the University of Massachusetts Amherst, College of Menominee Nation, Columbia University, Marine Biological Laboratory, University of Minnesota, University of Missouri Columbia, and University of Wisconsin-Madison have formed a consortium to host the NE CSC. This partnership with the U.S. Geological Survey climate science center network provides wide-reaching expertise, resources, and established professional collaborations in both climate science and natural and cultural resources management. This interdisciplinary approach is needed for successfully meeting the regional needs for climate impact assessment, adaptive management, education, and stakeholder outreach throughout the northeast region. Thus, the NE CSC conducts research, both through its general funds and its annual competitive award process, that responds to the needs of natural resource management partners that exist, in part or whole, within the NE CSC bounds. This domain includes the North Atlantic, Upper Midwest and Great Lakes, Eastern Tallgrass and Big Rivers, and Appalachian Landscape Conservation Cooperatives (LCCs), among other management stakeholders. For example, researchers are developing techniques to monitor tree range dynamics as affected by natural disturbances which can enable adaptation of projected climate impacts; conducting a Designing Sustainable Landscapes project to assess the capability of current and potential future landscapes in the Northeast to provide integral ecosystems and suitable habitat for a suite of

  20. The influence of negative charged centers on the hole transport in a typical molecularly doped polymer

    International Nuclear Information System (INIS)

    Graphical abstract: - Highlights: • Charged centers are introduced into a biased sample using an electron gun. • Two-layer multiple trapping model is used to describe charge carrier transport. • Model parameters are extracted from experimental data. • Current transients rise in the preflight region due to induced space charge. • Proposed model explains the observed effects semiquantitatively. - Abstract: We have studied effects of the negative charged centers on the time of flight (TOF) curves measured in a typical hole-conducting molecularly doped polymer. The main effects are the unusual TOF (surface generation) current rise in the preflight region (be it a flat plateau or a cusp) due to the accumulated space charge and the current reduction at all times because of the monomolecular recombination. TOF-2 (bulk generation) transients are less sensitive to charged centers. Analysis of these effects has proved that charged centers do not change the carrier mobility provided that the space charge field and bimolecular recombination are properly accounted for in terms of the proposed two-layer MT model. We have shown that combination of TOF, TOF-1a and TOF-2 variants of the electron-gun based technique allows one to establish definitively the character of the charge carrier transport in MDPs

  2. MDCC: Multi-Data Center Consistency

    CERN Document Server

    Kraska, Tim; Franklin, Michael J; Madden, Samuel

    2012-01-01

    Replicating data across multiple data centers not only allows moving the data closer to the user and, thus, reduces latency for applications, but also increases the availability in the event of a data center failure. Therefore, it is not surprising that companies like Google, Yahoo, and Netflix already replicate user data across geographically different regions. However, replication across data centers is expensive. Inter-data center network delays are in the hundreds of milliseconds and vary significantly. Synchronous wide-area replication is therefore considered to be unfeasible with strong consistency and current solutions either settle for asynchronous replication which implies the risk of losing data in the event of failures, restrict consistency to small partitions, or give up consistency entirely. With MDCC (Multi-Data Center Consistency), we describe the first optimistic commit protocol, that does not require a master or partitioning, and is strongly consistent at a cost similar to eventually consiste...

  3. Relativistic Guiding Center Equations

    Energy Technology Data Exchange (ETDEWEB)

    White, R. B. [PPPL; Gobbin, M. [Euratom-ENEA Association

    2014-10-01

    In toroidal fusion devices it is relatively easy that electrons achieve relativistic velocities, so to simulate runaway electrons and other high energy phenomena a nonrelativistic guiding center formalism is not sufficient. Relativistic guiding center equations including flute mode time dependent field perturbations are derived. The same variables as used in a previous nonrelativistic guiding center code are adopted, so that a straightforward modifications of those equations can produce a relativistic version.

  4. Nanoparticles as starting point for artificial pinning centers in superconductors

    International Nuclear Information System (INIS)

    Very small pinning centers in superconducting thin films were produced applying a patterning technique based on self-organization of salt-loaded spherical micelles made of diblock copolymers. The micelles are used to create metal nanoparticles, which were used as etching mask for structuring of suitable substrates. For this purpose, metal salts centered in a spherical polymer matrix are deposited as a monolayer on the surface of substrates, where they form a periodic, triangular lattice of medium-range order over 4-8 lattice constants by a self-organisation process. In a subsequent plasma treatment, the polymer matrix is removed completely, while the metal salts are reduced to metallic nanoparticles used as etching mask to transfer the resulting pattern into silicon substrates. Several samples containing such artificial pinning centers were characterized using a SQUID-magnetometer to obtain their magnetic moment, by high resolution electron microscopy and by transport measurements at low temperature. Although the order of the resulting artificial pinning centers is not perfect, pronounced integer and fractional matching features induced by commensurability effects when the vortex lattice matches the lattice of artificial pinning sites are observed within a wide temperature range. Due to their nanoscaled size, the artificial pinning sites guarantee single-vortex pinning even at temperatures well below Tc. Two types of critical currents, Ica and Icn, could be distinguished in transport measurements, indicating two different types of pinning mechanisms: Strong pinning on artificial pinning centers and weaker pinning by native, randomly positioned pinning centers and by caging in interstitial regions. For magnetic fields slightly larger than B1, these two critical current densities get indistinguishable because of an increasing number of interstitial vortices and their interaction with flux lines pinned at artificial pinning centers.

  17. Are we really seeing dark matter signals from the Milky Way center?

    CERN Document Server

    Gomez-Vargas, German A

    2014-01-01

    The center of the Milky Way is one of the most interesting regions of the $\\gamma$-ray sky because of the potential for indirect dark matter (DM) detection. It is also complicated due to the many sources and uncertainties associated with the diffuse $\\gamma$-ray emission. Many independent groups have claimed a DM detection in the data collected by the Large Area Telescope on board the Fermi $\\gamma$-ray Satellite from the inner Galaxy region at energies below 10 GeV. However, an exotic signal needs to be disentangled from the data using a model of known $\\gamma$-ray emitters, i.e. a background model. We point out that deep understanding of background ingredients and their main uncertainties is of capital importance to disentangle a dark matter signal from the Galaxy center.

    1998-12-16

    The aim of my research is to develop an economic geography theory to explain the global automotive recycling industry. The most profitable aspect of the ELV (end-of life vehicles) dismantling business is the export of used Japanese auto parts to the countries in Asia and the Pacific region. In Japan there are about 5000 dismantlers with most of them being of small to medium size. In developed countries, the average recycling rate by vehicle weight is about 75% with the remainder, mostly shredded residue, ending up in landfills. This landfill residue contains many environmentally polluting materials. Available landfill sites are quickly becoming exhausted, especially after illegal shredder residue dumping incidents. However, a business chance was created by environmental regulation and we can now observe car makers, dealers, steel companies, and insurance companies joining the dismantling business. (author)
