    Ethanol has recently been of great interest worldwide because it is a viable economic alternative to petroleum products and it is a renewable source of energy that mitigates the emission of greenhouse gases. Brazilian bioethanol from sugarcane is the most successful case at the world level because of its low cost and low level of greenhouse gas emissions. Brazil's success with sugarcane cannot be understood as based solely on a natural comparative advantage, but as a result of efforts that culminated in a positive trajectory of technological learning, relying mostly on incremental innovations. The purpose of this article is to analyze the key aspects of the innovation system built around the Brazilian sugarcane industry. It is based on the national innovation systems approach according to which innovation results from the interaction of different institutional actors. Institutional arrangements are analyzed as the basis for the innovative process, in particular R and D and the innovation policies and strategies of the main players in the sugarcane sector, including sugar and ethanol mills, industrial goods suppliers, public and private research institutions, and governmental agencies. - Research Highlights: → The Brazilian success in bioethanol is due to the sugarcane innovation system. → Private funds for R and D became central after IAA closure. → Nowadays Brazilian innovation system is transforming to keep its leadership. → Public funds for research in the second generation bioethanol.

    Full Text Available We introduce the Coupled Aerosol and Tracer Transport model to the Brazilian developments on the Regional Atmospheric Modeling System (CATT-BRAMS. CATT-BRAMS is an on-line transport model fully consistent with the simulated atmospheric dynamics. Emission sources from biomass burning and urban-industrial-vehicular activities for trace gases and from biomass burning aerosol particles are obtained from several published datasets and remote sensing information. The tracer and aerosol mass concentration prognostics include the effects of sub-grid scale turbulence in the planetary boundary layer, convective transport by shallow and deep moist convection, wet and dry deposition, and plume rise associated with vegetation fires in addition to the grid scale transport. The radiation parameterization takes into account the interaction between the simulated biomass burning aerosol particles and short and long wave radiation. The atmospheric model BRAMS is based on the Regional Atmospheric Modeling System (RAMS, with several improvements associated with cumulus convection representation, soil moisture initialization and surface scheme tuned for the tropics, among others. In this paper the CATT-BRAMS model is used to simulate carbon monoxide and particulate material (PM2.5 surface fluxes and atmospheric transport during the 2002 LBA field campaigns, conducted during the transition from the dry to wet season in the southwest Amazon Basin. Model evaluation is addressed with comparisons between model results and near surface, radiosondes and airborne measurements performed during the field campaign, as well as remote sensing derived products. We show the matching of emissions strengths to observed carbon monoxide in the LBA campaign. A relatively good comparison to the MOPITT data, in spite of the fact that MOPITT a priori assumptions imply several difficulties, is also obtained.

    Full Text Available The air transportation network in a country has a great impact on the local, national and global economy. In this paper, we analyze the air transportation network in Brazil with complex network features to better understand its characteristics. In our analysis, we built networks composed either by national or by international flights. We also consider the network when both types of flights are put together. Interesting conclusions emerge from our analysis. For instance, Viracopos Airport (Campinas City is the most central and connected airport on the national flights network. Any operational problem in this airport separates the Brazilian national network into six distinct subnetworks. Moreover, the Brazilian air transportation network exhibits small world characteristics and national connections network follows a power law distribution. Therefore, our analysis sheds light on the current Brazilian air transportation infrastructure, bringing a novel understanding that may help face the recent fast growth in the usage of the Brazilian transport network.

    This work aims to identify actions that can be implemented to increase the energy efficiency of processes involved in the value chain of natural gas, specifically in the process of heating in existing city-gates of transporting natural gas Brazilians plants. The goal is increase supply of gas in Brazil. The main function of city-gates is to deliver the natural gas in contract terms (flow, pressure, temperature and quality). The main issue related to the consumption of natural gas fuel in city-gates is related to the operation (set-up and control) of natural gas combustion, in other words, depends on how the heating system is adjusted dynamically to burn, efficiently, the exact amount of gas required by this system, depending on temperature, pressure, temperature, quality and flow of natural gas at the 'city-gates'. The main objective of this work is to present a study on alternatives at design, set-up and control of natural gas city-gates (transport) in Brazil, aiming to increase the energy efficiency of this facility, and thus contributing to the growth in supply of natural gas available to the market.

  7. The Brazilian electrical system reform

    Mendonca, A.F.; Dahl, C.

    1999-01-01

    Although the Brazilian electrical system has been a public monopoly, the threat of electricity shortages from a lack of investment triggered a comprehensive reform. In 1993 the government began a series of laws, decrees and regulations reforming the tariff policy, allowing privatization of utilities, foreign investments and independent power producers, and creating an independent transmission grid and a new electricity regulatory agency (ANEEL). The new regulatory framework is not completely defined but the proposed model intends to transform bulk electricity supply into a competitive market similar to that adopted in England. Our objective is to evaluate whether the proposed reform will succeed in attracting the required private capital, will allow an unregulated wholesale electricity market and will require a strict regulatory framework. The reform has been quite successful in privatizing the distribution companies but is allowing monopolistic rents, and has failed until now to attract private investments to expand generation capacity. The risk of blackouts has increased, and the proposed wholesale electricity market may not be appropriate because of barriers to constructing new hydroelectric units, now 90% of the system. Therefore, a new regulatory framework and a strong regulatory agency with a well-defined tariff policy should have preceded the privatization. (author)

  8. The Northeast Brazilian Rift System

    1992-08-01

    The northeast Brazilian rift basins provide important data critical to the understanding of continental rifting processes associated with the opening of the South Atlantic. These basins represent the locus of intersection of the Southern and Equatorial branches and some basins yield substantial chronostratigraphic data that constrain the temporal and spatial interaction of the rift phases. Similar data are not found in its counterpart in Africa, especially for the Neocomian. These Early Cretaceous rift basins of northeast Brazil illustrate key three-dimensional geometries of intracontinental rift systems, mainly controlled by the basement structural framework. During the main rift phase (Syn-rift II, Neocomian-early Barremian) extensional deformation was distributed over three main rift axes: (1) the Gabon-Sergipe Alagoas (GSA) trend, (2) the Recôncavo-Tucano-Jatobá (RTJ) trend and (3) the Cariri-Potiguar (CP) trend. During this phase, extensional deformation jumped west from the easternmost basins (GSA trend) to a series of NE trending intracratonic basins (RTJ and CP trends), characterized by a set of asymmetric half grabens separated by basement highs, transfer faults, and/or accommodation zones. These basins are typically a few tens of kilometers wide and trend NE-SW, roughly perpendicular to the main extension direction during the Neocomian. Preexisting upper crustal weakness zones, like the dominantly NE-SW trending shear zones of the Brazilian/Pan-African orogeny, controlled the development of intracrustal listric normal faults. Internal transverse structures such as transfer faults and accommodation zones were also controlled by the local basement structural framework. The megashear zones of Pernambuco (Brazil) and Ngaundere (Africa) seem to have behaved like a huge accommodation zone, accommodating extensional deformation along the RTJ/GSA trends with simultaneous extension along the CP trend. During the late Barremian (Syn-rift phase III), a significant

    A great increase in the installation of stand-alone PV systems for rural electrification is expected in Brazil for the next years due to a government program named Luz para Todos. However, there is a major concern for the quality of the equipment and systems to be acquired and installed, which led to an initiative, coordinated by INMETRO - Brazilian Institute for Metrology, Standardisation and Industrial Quality (Instituto Brasileiro de Metrologia, Normalizacao e Qualidade Industrial), joining several institutions to establish a programme for labelling these equipment. The adopted requirements are discussed in the present article. (author)

  12. State and market in post-reform Brazilian air transportation

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available The changes that have taken place in Brazilian air transportation following the cycle of “market reforms” have turned this sector into an object of growing interest. This interest, in turn, has led to the emergence of a broad literature on the subject, characterized by the emphasis on an agenda of liberalization and the critique of State activism. The goal of the present article is to promote a confrontation between the different interpretations that have been made, incorporating the contributions of approaches inspired in Economic Sociology and in institutionalist analyses in order to draw attention to the importance that political variables, and the State in particular, have for economic performance. The post-reform context is characterized by an initial moment of greater State activism regarding air transportation, through re-initiation of stricter regulatory mechanisms and the re-opening of channels of dialog between state actors and firms. This is followed by a second moment in which state activism is abandoned, at the same time that the sector demonstrates expressive rates of growth, pushing it beyond its existing capacity and flight support infrastructure. This culminated in the episode known as the “apagão aéreo” (aerial black out Analysis of testimonies of state and private sector actors regarding the “blackout” enables us to identify the flaws in the responsible state apparatus as one of the factors that led to the “blackout”. Our conclusions draw attention to the importance of taking political factors into consideration, and particularly the role of the State, in the development of air transportation in Brazil.

    Full Text Available The Brazilian education system provides a specific form of organization for the inclusive education of students with disabilities. Law No. 9394 dated December 20, 1996, “Lei de diretrizes e bases da educação nacional”, presents in Chapter V the “educação especial" as a form of organization offered to students "portadores de Necessidades especiais”. Admission of students with disabilities in the Brazilian schools was characterized by several phases: the welfarist phase, the integration phase and the inclusion phase, which is the most recent one and now being debated. The presence of a special device fosters the differences, even when everybody enters the classbecause a separation perspective damps down all the procedural and design efforts towards a true integration, holding back collaboration and action sharing among teachers. We consider however effective an action that accompanies the gradual learning evolution mediating between the student with disabilities and peers, between him and the teachers, between him and the learning tools designed.

  16. Energetic transition in the transport sector: Brazilian case

    International Nuclear Information System (INIS)

    Jannuzzi, Gilberto de Martino

    1999-01-01

    With the exception of the pipelines, the electrified railroad, the metro and some other urban systems, the transport depends totally on fossil fuels. The alternative fuels continue being a source of energy of smaller importance to global level, and Brazil it is the only country that maintains a program to great scale of derived liquid fuel of the biomass like substitute of the gasoline. Here we try to characterize the stage of energetic transition of the transport in Brazil, by means of the consolidation of the program of alcohol. The country has introduced a new fuel successfully that although it presents environmental benefits when not contributing to the net increase of gases that produce the greenhouse effect (GHG), it has turned out to be not very economic. Improvements in public transportation, the regional use of the alcohol, and bigger vehicular efficiency are some of the addresses that the energetic politics should take regarding a more sustainable energetic future for the national transport sector

    This historic-sociologic study aims to analyse the challenges faced by the Brazilian Expeditionary Force's Air Transportation Nurses of the Army with the Theatre of Operations on the course of World War II. The primary source was comprised of a photograph from this time period and oral testimonies of those who participated in the conflict. Ideas by sociologist Pierre Bourdieu support the discussion. Results suggest that Brazilian nurses were challenged to transport the wounded without medical advice. We conclude that the challenge to fulfill the task imposed, which led to independent decision-making, gave confidence and autonomy to the ones already responsible for the transportation of the wounded.

    1988-09-01

    The Transportable Criticality Alarm System was developed at the Hanford Site in 1982 to comply with the requirements of US Department of Energy Order DOE 5480.1, 12/18/80, and ANSI/ANS-8.3- 1979. The portable unit that it replaced failed to comply with the new requirements in that it did not provide the necessary warning of malfunctions, nor did it provide the Hanford Site standard criticality alarm signal. Modern technology allowed the Transportable Criticality Alarm System to comply with the criticality requirements cited and to incorporate other features that make it more usable, maintainable, and reliable. The Transportable Criticality Alarm System (TCAS) provides temporary criticality coverage in manned areas where the facility criticality alarm system is not operable. This gamma radiation-sensitive system has been in use for the past 6 yr at the Hanford Site. 2 refs., 4 figs., 1 tab

    In the nuclear fuel cycle, a lot of radioactive materials are produced. These radioactive materials must be transported in order to promote the integration of the fuel cycle units. Considerations about the transport characteristics of radioactive material were made for each section of the fuel cycle. These considerations were based on the experience of several countries and in accordance with the International Atomic Energy Agency regulations. A prediction of transport demands for the Brazilian Nuclear Program until year 2.010 was made. The prediction refers mainly to the quantity of radioactive material produced in each section of the cycle the quantity of vehicles needed for the transport of these materials. Several safety aspects were considered specially, the accidents predictions for years 2.000 and 2.010. The accident probability in Brazilian railroads and highways was compared with that of the USA.

    This book shows how the systems approach is employed by scientists in various countries to solve specific problems concerning railway transport. In particular, the book describes the experiences of scientists from Romania, Germany, the Czech Republic, the UK, Russia, Ukraine, Lithuania and Poland. For many of these countries there is a problem with the historical differences between the railways. In particular, there are railways with different rail gauges, with different signaling and communication systems, with different energy supplies and, finally, with different political systems, which are reflected in the different approaches to the management of railway economies. The book’s content is divided into two main parts, the first of which provides a systematic analysis of individual means of providing and maintaining rail transport. In turn, the second part addresses infrastructure and management development, with particular attention to security issues. Though primarily written for professionals involved...

    The objective of this analysis is to identify issues and criteria that apply to the design of the Subsurface Emplacement Transportation System (SET). The SET consists of the track used by the waste package handling equipment, the conductors and related equipment used to supply electrical power to that equipment, and the instrumentation and controls used to monitor and operate those track and power supply systems. Major considerations of this analysis include: (1) Operational life of the SET; (2) Geometric constraints on the track layout; (3) Operating loads on the track; (4) Environmentally induced loads on the track; (5) Power supply (electrification) requirements; and (6) Instrumentation and control requirements. This analysis will provide the basis for development of the system description document (SDD) for the SET. This analysis also defines the interfaces that need to be considered in the design of the SET. These interfaces include, but are not limited to, the following: (1) Waste handling building; (2) Monitored Geologic Repository (MGR) surface site layout; (3) Waste Emplacement System (WES); (4) Waste Retrieval System (WRS); (5) Ground Control System (GCS); (6) Ex-Container System (XCS); (7) Subsurface Electrical Distribution System (SED); (8) MGR Operations Monitoring and Control System (OMC); (9) Subsurface Facility System (SFS); (10) Subsurface Fire Protection System (SFR); (11) Performance Confirmation Emplacement Drift Monitoring System (PCM); and (12) Backfill Emplacement System (BES)

    Full Text Available The Brazilian party system presents a paradox. Although the Workers Party (PT and the Brazilian Social Democratic Party (PSDB have controlled presidential elections for the last 20 years, their force at the other levels of electoral competition has not grown. The objective of this study is to undertake a discussion of this situation through the 2014 general elections. After attempting to explain why successive challengers have not been able to change the structure of competition for the Brazilian presidency, I will analyze the relation established between the pattern observed at this level and the other “connected” electoral disputes—both those for state executive and federal legislative office. The general conclusion is that even if the pattern continues, it is quite improbable that this will significantly impact the other levels of national political party competition.

    Roads provide the main means of transportation in Brazil. According to data from the Brazilian Department of Infrastructure and Transport, 96.2% of the passenger transportation and 61.8% of the cargo transportation are based on road infrastructure. However, three quarters of the Brazilian roads are in terrible, unsatisfactory or generally inadequate condition. Poor road conditions are responsible for a great number of accidents with severe consequences for the population and the environment. Given the importance of this matter, there is a need to develop an intelligent system for automatic classification of social and environmental sensitivity maps in order to support actions that respond to emergencies and to help in transportation planning, especially considering the heavy movement of hazardous cargoes such as petroleum and its derivates. For this, tools such as Geographic Information System (GIS) allow social-environmental and traffic engineering characterization maps to be analyzed on a unified, geo referenced digital base. This way, administrators can estimate which stretches of the network are more environmentally sensitive and which pose greater risks, and therefore draw inferences on the most socially and environmentally vulnerable. Social and environmental vulnerability data not only help in the classification of the areas which pose the greater risks, but also make it possible to decide on emergency support points, creating a culture of prevention in the area of hazardous cargo transportation. The case study on the state of Rio Grande do Norte provides a measure of the importance of such work. The city of Natal - the state capital - and the Guamare petrochemical facility are interconnected by 180 Km Road, on which more than 100 tanker trucks loaded with diesel and its derivates travel every day.

    International Nuclear Information System (INIS)

    1986-01-01

    The first proton beams have been transported along the transfer beamline and the diagnostic components have thus been used and tested under real operating conditions. The various electronic systems have been linked to the control system and the equipment can now be operated from the control console. The performance of the diagnostic system for the transfer beamline is satisfactory. The beam diagnostic components for the high-energy beamlines up to the isotope production and neutron therapy vaults and the first experimental target rooms have been installed. The high-energy slits have been delivered. The scanner and harp electronics have been installed and linked to their respective components in the beamlines. The pneumatic acuator control electronics has been manufactured, installed and is operational; provision has been made for special control features of the equipment in the therapy beamline. The high-voltage bias supply for the Faraday cups has been implemented. The installation of the beam current measurement system is nearing completion although part of it is already operational. A coaxial relay multiplexer for the capacitive phase probe signals has been manufactured and installed. The diagnostic equipment for the beamlines to isotope production and neutron therapy is thus ready for operation. 4 figs

    2006-08-16

    The Nuclear Waste Policy Act of 1982 (NWPA), as amended, authorized the DOE to develop and manage a Federal system for the disposal of SNF and HLW. OCRWM was created to manage acceptance and disposal of SNF and HLW in a manner that protects public health, safety, and the environment; enhances national and energy security; and merits public confidence. This responsibility includes managing the transportation of SNF and HLW from origin sites to the Repository for disposal. The Transportation System Concept of Operations is the core high-level OCRWM document written to describe the Transportation System integrated design and present the vision, mission, and goals for Transportation System operations. By defining the functions, processes, and critical interfaces of this system early in the system development phase, programmatic risks are minimized, system costs are contained, and system operations are better managed, safer, and more secure. This document also facilitates discussions and understanding among parties responsible for the design, development, and operation of the Transportation System. Such understanding is important for the timely development of system requirements and identification of system interfaces. Information provided in the Transportation System Concept of Operations includes: the functions and key components of the Transportation System; system component interactions; flows of information within the system; the general operating sequences; and the internal and external factors affecting transportation operations. The Transportation System Concept of Operations reflects OCRWM's overall waste management system policies and mission objectives, and as such provides a description of the preferred state of system operation. The description of general Transportation System operating functions in the Transportation System Concept of Operations is the first step in the OCRWM systems engineering process, establishing the starting point for the lower

    2012-10-01

    This article presents a model of the healthcare value chain which consists of a schematic representation of the Brazilian healthcare system. The proposed model is adapted for the Brazilian reality and has the scope and flexibility for use in academic activities and analysis of the healthcare sector in Brazil. It places emphasis on three components: the main activities of the value chain, grouped in vertical and horizontal links; the mission of each link and the main value chain flows. The proposed model consists of six vertical and three horizontal links, amounting to nine. These are: knowledge development; supply of products and technologies; healthcare services; financial intermediation; healthcare financing; healthcare consumption; regulation; distribution of healthcare products; and complementary and support services. Four flows can be used to analyze the value chain: knowledge and innovation; products and services; financial; and information.

    In Brazil, the scorpion species responsible for most severe incidents belong to the Tityus genus and, among this group, T. serrulatus , T. bahiensis , T. stigmurus and T. obscurus are the most dangerous ones. Other species such as T. metuendus , T. silvestres, T. brazilae , T. confluens , T. costatus , T. fasciolatus and T. neglectus are also found in the country, but the incidence and severity of accidents caused by them are lower. The main effects caused by scorpion venoms - such as myocardial damage, cardiac arrhythmias, pulmonary edema and shock - are mainly due to the release of mediators from the autonomic nervous system. On the other hand, some evidence show the participation of the central nervous system and inflammatory response in the process. The participation of the central nervous system in envenoming has always been questioned. Some authors claim that the central effects would be a consequence of peripheral stimulation and would be the result, not the cause, of the envenoming process. Because, they say, at least in adult individuals, the venom would be unable to cross the blood-brain barrier. In contrast, there is some evidence showing the direct participation of the central nervous system in the envenoming process. This review summarizes the major findings on the effects of Brazilian scorpion venoms on the central nervous system, both clinically and experimentally. Most of the studies have been performed with T. serrulatus and T. bahiensis . Little information is available regarding the other Brazilian Tityus species.

    De Seta, Marismary Horsth; Dain, Sulamis

    2010-11-01

    This paper analyzes the Brazilian Sanitary Surveillance System as an arrangement aimed at regulating and reducing health risks associated with consumption of products, use of health services and the environment. Historical, political and tax aspects were considered and their development compared with the National Health Surveillance System, which has received strong international cooperation. The comparison was based on the trajectory of their national systems and related federal agencies, as well as on criteria adopted for decentralization. The central category of analysis is federative coordination and was based on the framework of federalism and intergovernmental relations. The institutional context of health and sanitary surveillance presents strong political competition, instability in the project and probable reduction of the ability of federal coordination after the Pact for Health. The National Sanitary Surveillance System due to its nature of public good and high externality in its field of action requires federal coordination for increasing the regional and local cooperation, also because of the structural heterogeneity of Brazilian municipalities.

  3. Energy, Pollutant Emissions and Other Negative Externality Savings from Curbing Individual Motorized Transportation (IMT: A Low Cost, Low Technology Scenario Analysis in Brazilian Urban Areas

    Directory of Open Access Journals (Sweden)

    Ursula Maruyama

    2012-03-01

    Full Text Available This article examines the inefficient use of resources in the Brazilian transportation system. The energy use growth and external cost generation in this essential economic sector are considerable, and the trend is towards an increasing problem in the coming years. The continued expansion of Brazilian cities and the increase in demand for mobility is a result of a substantial growth in the number of road transport users, as increased earnings enable lower income groups to acquire and use individual motorized means of transport. The aim of this paper is to estimate the potential gains from reducing individual motorized transport by the year 2020. This investigation concludes that in a conservationist scenario, by prioritizing low cost, low technology public policies—which include operation of Bus Rapid Transit systems, walking and cycling facilities and congestion charges, among others—it should be possible to save over USD 30 billion and USD 26 billion in external transportation and infrastructure costs, respectively, up to 2020. In addition, these public policies can save more than 35 million Tons of Oil Equivalents in energy consumption and avoid almost 4,000 thousand tons of local pollution emissions and 37,500 thousand tons of GHG emissions in the same period.

    Full Text Available The study aims at analyzing comparatively the representativeness of foreign capital in the capital of Brazilian companies of the sectors construction and transports, considering their segments on the BM&FBovespa. The internationalization of the 66 companies in the sample was measured by the percentage of the company's share capital held by foreign investors, and governance by the company's participation on the “Differentiated Level of Corporate Governance” (DLCG segments of BM&FBovespa. Using a descriptive and a quantitative study, the results of applying the Mann-Whitney test for the percentage of foreign capital in the capital of DLCG firms and of companies listed on the traditional market indicate that there is a difference statistically significant between the two groups of firms, confirming the hypothesis of this research. The conclusion is that governance is a sign of the internationalization of capital companies, confirming the efficiency of the administration based on the theory of transaction costs.

    NASA-Langley's Advanced Transport Operating Systems Program employs a heavily instrumented, B 737-100 as its Transport Systems Research Vehicle (TRSV). The TRSV has been used during the demonstration trials of the Time Reference Scanning Beam Microwave Landing System (TRSB MLS), the '4D flight-management' concept, ATC data links, and airborne windshear sensors. The credibility obtainable from successful flight test experiments is often a critical factor in the granting of substantial commitments for commercial implementation by the FAA and industry. In the case of the TRSB MLS, flight test demonstrations were decisive to its selection as the standard landing system by the ICAO.

    predominance of road transport causes severe environmental impacts. In CW, road transport contributed 19% to climate change and 24% to cumulative energy demand, while in SO it contributed 12% and 15% to these impacts, respectively. Improvements in the logistics of transportation, giving priority to rail and river transports over road transport, can contribute significantly to reducing greenhouse gas emissions and decreasing energy use. Future studies involving Brazilian soybeans should take into account the region of origin as different levels of environmental impact are predicted. 2010 Elsevier Ltd. All rights reserved.

    Scientific and technological development is crucial for advancing the Brazilian health system and for promoting quality of life. The way in which the Brazilian Ministry of Health has supported clinical research to provide autonomy, self-sufficiency, competitiveness and innovation for the healthcare industrial production complex, in accordance with the National Policy on Science, Technology and Innovation in Healthcare, was analyzed. Descriptive investigation, based on secondary data, conducted at the Department of Science and Technology, Ministry of Health. The Ministry of Health's research management database, PesquisaSaúde, was analyzed from 2002 to 2009, using the key word "clinical research" in the fields "primary sub-agenda" or "secondary sub-agenda". The 368 projects retrieved were sorted into six categories: basic biomedical research, preclinical studies, expanded clinical research, clinical trials, infrastructure support and health technology assessment. From a structured review on "clinical research funding", results from selected countries are presented and discussed. The amount invested was R$ 140 million. The largest number of projects supported "basic biomedical research", while the highest amounts invested were in "clinical trials" and "infrastructure support". The southeastern region had the greatest proportion of projects and financial resources. In some respects, Brazil is ahead of other BRICS countries (Russia, India, China and South Africa), especially with regard to establishing a National Clinical Research Network. The Ministry of Health ensured investments to encourage clinical research in Brazil and contributed towards promoting cohesion between investigators, health policies and the healthcare industrial production complex.

    A fundamental premise of most applied transport models is the existence and uniqueness of an equilibrium solution that balances demand x(t) and supply t(x). The demand consists of the people that travel in the transport system and on the defined network, whereas the supply consists of the resulting...... level-of-service attributes (e.g., travel time and cost) offered to travellers. An important source of complexity is the congestion, which causes increasing demand to affect travel time in a non-linear way.

    Kibrit, Eduardo; Zouain, Desiree Moraes

    2005-01-01

    The present work is a proposal for developing a quality management system for Brazilian nuclear installations, based on applicable standards. The standard ISO 9001:2000 [4] establishes general requirements for the implementation of a quality management system in all kinds of organizations. The standard IAEA 50-C/SG-Q [1] establishes general requirements for the implementation of a quality assurance system in nuclear installations. The standard CNEN-NN- 1.16 [5] establishes the regulating requirements for the quality assurance systems and programs of nuclear installations, for licensing and authorization for operation of these installations in Brazil. The revision of standard IAEA 50-C/SG-Q [1], to be replaced by IAEA DS 338 [2] and IAEA DPP 349 [3], introduces the concept of 'Integrated Management System' for the nuclear area, in preference to the concept of 'Quality Assurance'. This approach is incorporated with the current tendency, because it guides the system to manage, in an integrated way, the requirements of quality, safety, health, environment, security and economics of the installation. The results of the characterization of the quality management systems established in the applicable standards are presented, with the determination of the common and conflicting points among them. Referring data to quality assurance program/quality management system in some nuclear installations of IAEA Member States are also presented. (author)

    Simple Summary The inclusion of societal input is needed for food animal production industries to retain their “social license to operate”. Little is known about the knowledge and attitudes of Brazilian citizens regarding food animal production systems. The aim of this study was to explore the beliefs and attitudes of Brazilians not associated with livestock production towards farm animal production systems. Overall, our participants expressed a preference for free-range, cage-free, and more “natural” production systems. They also expressed concerns with livestock production systems that limited the movement or expression of natural behaviours, particularly those that they associated with animal suffering or distress. They recognized farm animals as deserving respect and dignity beyond the provision of basic needs. Our findings indicate that Brazil’s current farm animal housing practices that are associated with restriction of movement may not align with societal expectations. Abstract The inclusion of societal input is needed for food animal production industries to retain their “social license to operate”; failure to engage with the public on this topic risks the long-term sustainability of these industries. The primary aim of this study was to explore the beliefs and attitudes of Brazilians citizens not associated with livestock production towards farm animal production. A related secondary aim was to identify the specific beliefs and attitudes towards systems that are associated with restriction of movement. Each participant was shown pictures representing two of five possible major food animal industries (laying hens, beef cattle, pregnant sows, lactating sows, and poultry meat). Participants were presented a six pages survey that included demographic questions plus two sets of two pictures and a series of questions pertaining to the pictures. Each set of pictures represented a particular industry where one picture represented a housing type that

    Full Text Available The automotive business in Brazil achieved 10% of the industry revenue and 6% of the formal employment by 2008. The commercial vehicle segment concentrated so far eight truck makers that experienced their best market figures in 2008, the economy crisis in 2009, and an extraordinary recovery in 2010. Government tax reduction programs as well as special financing incentives were undoubtedly decisive to re-stimulate the business during the crisis. Positive Brazilian perspectives with the boom in the agricultural, oil and gas, mining and infrastructure activities plus the coming sports events call the attention of new players that are quickly implementing different business strategies to become part of the game. New emission regulations starting from 2012 also bring uncertainties, challenges and opportunities. With the growing globalization and market concentration it's critical for any industry understand and minimize the forces of competitive pressures. The main goal of this paper, therefore, is to contribute to the academy with an alternative approach of strategic and behavioral analysis of rivalry and competition different than the five forces model of Porter. Ford, Iveco, MAN, Mercedes-Benz, Scania and Volvo were assessed from 2008 to 2010 within three main performance indicators – unit sales, gross revenues and operating profits – supporting the elaboration of the competitive pressure systems mapping model of D'aveni, including a hypothetical future scenario with a new entrant and the potential impacts in the system. Main findings and results portray the asymmetrical strategic behavior of competitors and the temporary dynamic stability in the Brazilian truck industry.

    Intermodal container monitoring is considered a major security issue in many major logistic companies and countries worldwide. Current representation of the problem, we face today, originated in 2002, right after the 9/11 attacks. Then, a new worldwide Container Security Initiative (CSI, 2002) was considered that shaped the perception of the transportation operations. Now more than 80 larger ports all over the world contribute to its further development and integration into everyday transportation operations and improve the regulations for the developing regions. Although, these new improvements allow us to feel safer and secure, constant management of transportation operations has become a very difficult problem for conventional data analysis methods and information systems. The paper deals with a proposal of a whole new concept for the improvement of the Containers Security Initiative (CSI) by virtually connecting safety, security processes and systems. A conceptual middleware approach with deployable intelligent agent modules is proposed to be used with possible scenarios and a testbed is used to test the solution. Middleware examples are visually programmed using National Instruments LabView software packages and Wireless sensor network hardware modules. An experimental software is used to evaluate he solution. This research is a contribution to the intermodal transportation and is intended to be used as a means or the development of intelligent transport systems.

    Rich iron ore deposits were discovered during the 1960's in the mountain range of Serra dos Carajas, State of Para, Brazil, near the headwaters of the Tocantins River some 400 miles southwest from the state capital of Belem. The key to the successful exploitation of this deposit was the development of an efficient an economical transportation system. Starting in 1972 extensive surveys and studies were carried out by Soros Associates on behalf of CVRD to determine the optimum way of transporting the ore from the mine site to the markets, most of which are located overseas. Overland transportation to the coast, loading into seagoing vessels and the ocean voyage to the ports of destination was treated as an integrated system in these studies.

    Many biological and man-made systems rely on transport systems for the distribution of material, for example matter and energy. Material transfer in these systems is determined by the flow rate and the concentration of material. While the most concentrated solutions offer the greatest potential in terms of material transfer, impedance typically increases with concentration, thus making them the most difficult to transport. We develop a general framework for describing systems for which impedance increases with concentration, and consider material flow in four different natural systems: blood flow in vertebrates, sugar transport in vascular plants and two modes of nectar drinking in birds and insects. The model provides a simple method for determining the optimum concentration copt in these systems. The model further suggests that the impedance at the optimum concentration μopt may be expressed in terms of the impedance of the pure (c = 0) carrier medium μ0 as μopt∼2αμ0, where the power α is prescribed by the specific flow constraints, for example constant pressure for blood flow (α = 1) or constant work rate for certain nectar-drinking insects (α = 6). Comparing the model predictions with experimental data from more than 100 animal and plant species, we find that the simple model rationalizes the observed concentrations and impedances. The model provides a universal framework for studying flows impeded by concentration, and yields insight into optimization in engineered systems, such as traffic flow. PMID:23594815

    An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the percentage distribution of exergy destruction in the different units of the processing plants is characterized. An exergoeconomy methodology is developed and applied to properly allocate the renewable and non-renewable exergy costs and CO 2 emission cost among the different products of multiproduct plants. Since Brazilian electricity is consumed in the upstream processing stages of the fuels used in the generation thereof, an iterative calculation is used. The electricity mix comprises thermal (coal, natural gas and oil-fired), nuclear, wind and hydroelectric power plants, as well as bagasse-fired mills, which, besides exporting surplus electricity, also produce sugar and bioethanol. Oil and natural gas-derived fuels production and biodiesel fatty acid methyl-esters (FAME) derived from palm oil are also analyzed. It was found that in spite of the highest total unit exergy costs correspond to the production of biofuels and electricity, the ratio between the renewable to non-renewable invested exergy (cR/cNR) for those fuels is 2.69 for biodiesel, 4.39 for electricity, and 15.96 for ethanol, whereas for fossil fuels is almost negligible. - Highlights: • Total and non-renewable exergy costs of Brazilian transportation fuels are evaluated. • Specific CO 2 emissions in the production of Brazilian transportation fuels are determined. • Representative production routes for fossil fuels, biofuels and electricity are reviewed. • Exergoeconomy is used to distribute costs and emissions in multiproduct processes

  9. Physical System Requirements: Transport Waste

    International Nuclear Information System (INIS)

    1992-04-01

    The Nuclear Waste Policy Act (NWPA) of 1982 assigned to the Department of Energy (DOE) the responsibility for managing the disposal of spent nuclear fuel and high-level radioactive waste and established the Office of Civilian Radioactive Waste Management (OCRWM) for that purpose. The Secretary of Energy, in his November 1989 report to Congress (DOE/RW-0247), announced three new initiatives for the conduct of the Civilian Radioactive Waste Management (CRWM) program. One of these initiatives was to establish improved management structure and procedures. In response, OCRWM performed a management study and the Director subsequently issued the Management Systems Improvement Strategy (MSIS) on August 10, 1990, calling for a rigorous implementation of systems engineering principles with a special emphasis on functional analysis. The functional analysis approach establishes a framework for integrating the program management efforts with the technical requirements analysis into a single, unified, and consistent program. This approach recognizes that just as the facilities and equipment comprising the physical waste management system must perform certain functions, so must certain programmatic and management functions be performed within the program in order to successfully bring the physical system into being. The objective of this document is to establish the essential functions, requirements, interfaces, and system architecture for the Transport Waste mission. Based upon the Nuclear Waste Policy Act, the mission of the Waste Transportation System is to transport SNF and/or HLW from the purchaser's/producer's facilities to, and between, NWMS facilities in a manner that protects the health and safety of the public and of workers and the quality of the environment makes effective use of financial and other resources, and to the fullest extent possible uses the private sector

    Full Text Available The activity and kinetics of soil phosphatases are important indicators to evaluate soil quality in specific sites such as the Cerrado (Brazilian Savanna. This study aimed to determine the activity and kinetic parameters of soil phosphatase in Cerrado systems. Soil phosphatase activity was assessed in samples of native Cerrado (NC, no-tillage (NT, conventional tillage (CT and pasture with Brachiaria brizantha (PBb and evaluated with acetate buffer (AB, tris-HCl buffer (TB, modified universal buffer (MUB and low MUB. The Michaelis-Menten equation and Eadie-Hofstee model were applied to obtain the kinetic parameters of soil phosphatase using different concentrations of p-nitrophenol phosphate (p-NPP. MUB showed the lowest soil phosphatase activity in all soils whereas AB in NC and NT presented the highest. Low MUB decreased interferences in the assessment of soil phosphatase activity when compared to MUB, suggesting that organic acids interfere on the soil phosphatase activity. In NC and NT, soil phosphatase activity performed with TB was similar to AB and low MUB. Km values from the Michaels-Menten equation were higher in NC than in NT, which indicate a lower affinity of phosphatase activity for the substrate in NC. Vmax values were also higher in NC than in NT. The Eadie-Hofstee model suggests that NC had more phosphatase isoforms than NT. The study showed that buffer type is of fundamental importance when assessing soil phosphatase activity in Cerrado soils.

    Full Text Available The inclusion of societal input is needed for food animal production industries to retain their “social license to operate”; failure to engage with the public on this topic risks the long-term sustainability of these industries. The primary aim of this study was to explore the beliefs and attitudes of Brazilians citizens not associated with livestock production towards farm animal production. A related secondary aim was to identify the specific beliefs and attitudes towards systems that are associated with restriction of movement. Each participant was shown pictures representing two of five possible major food animal industries (laying hens, beef cattle, pregnant sows, lactating sows, and poultry meat.

    1999-01-01

    The use of Ethanol as a fuel is a significant contribution to the efforts for reducing greenhouse effect related to gas emissions. The main objective of the present work, is to assess Brazil's performance regarding activities aimed at reducing harmful gas emissions, in the global context of the intensification of the greenhouse effect, assumed as a working hypothesis. Brazil's estimated emissions of greenhouse effect related to gases are far less than those of developed countries. The per capita consumption of energy and of fossil fuels is still quite low in Brazil. However, the means for reducing harmful gas emissions and the initiatives to control the greenhouse effect should not be directed to the maintenance of the present low level of energy consumption, for this would have negative repercussion on the economic development of the country. Developed countries have focused on the more rational uses of energy, i.e. more efficient and less polluting fuels, so as to reduce their own levels of greenhouse effect related to gas emissions. In this connection, the use of ethanol in Brazil for the transportation sector may prove to be an important alternative furthering the efforts to stabilised the actual level of gases in the atmosphere. The energy derived from biomass, and in this case, from a renewable, clean source, i.e., from sugar cane, has the unquestionable advantage of permitting the almost complete reabsorption of Carbon Dioxide emitted through the combustion of fuel alcohol. This closed cycle allows, in principle, to increase the energy supply, essential for sustained economic growth, without hazards to the environment. Furthermore, the Brazilian Fuel Alcohol Program has the potential to attract international interest as an important alternative relative to the efforts for controlling the global dangers of the greenhouse effect, as will be discussed in greater detail further on in this paper.

    Full Text Available This paper is concerned with mood distribution in European and Brazilian Portuguese. Although, in many cases, these two varieties do not differ as regards the selected mood, there are exceptions in some contexts. The variations involve rather different constructions, at first sight suggesting a chaotic picture. However, if one assumes that mood is associated with the expression of an attitude towards a proposition (in other words, that mood is an expression of modality, it becomes clear that European and Brazilian Portuguese are diverging in respect to the relevant factors for mood selection. In particular, while in European Portuguese the selection of mood is sensitive to both veridicality and epistemic modality, Brazilian Portuguese is becoming a language where the truth-value of the proposition is the main factor responsible for mood selection. Hence, a tendency appears to be developing for Brazilian Portuguese to approach the pattern found in languages like Rumanian, (Modern Greek or Hungarian, while European Portuguese follows the pattern found in most other Romance languages.

    This developmental effort clearly shows that a Road Transportable Analytical Laboratory System is a worthwhile and achievable goal. The RTAL is designed to fully analyze (radioanalytes, and organic and inorganic chemical analytes) 20 samples per day at the highest levels of quality assurance and quality control. It dramatically reduces the turnaround time for environmental sample analysis from 45 days (at a central commercial laboratory) to 1 day. At the same time each RTAL system will save the DOE over $12 million per year in sample analysis costs compared to the costs at a central commercial laboratory. If RTAL systems were used at the eight largest DOE facilities (at Hanford, Savannah River, Fernald, Oak Ridge, Idaho, Rocky Flats, Los Alamos, and the Nevada Test Site), the annual savings would be $96,589,000. The DOE's internal study of sample analysis needs projects 130,000 environmental samples requiring analysis in FY 1994, clearly supporting the need for the RTAL system. The cost and time savings achievable with the RTAL system will accelerate and improve the efficiency of cleanup and remediation operations throughout the DOE complex

    The system of the present invention comprises a self-forklift for transporting vessels which contain radioactive wastes generated in a power facility to a storage warehouse and a unmanned remote control salvaging vehicle for drawing out the forklift when it is disabled in the storage warehouse for repair. Namely, the self forklift runs by itself on a predetermined route to transport and unload the vessels to a predetermined position in the storage warehouse. When the self forklift is stopped by failure in the storage warehouse, the unmanned salvaging vehicle takes the self forklift to the outside by operator's remote control while observing a monitor of an TV camera attached to the vehicle. In this case, the self forklift has a salvaging hook at a position of the body corresponding to a driving front wheel. The unmanned salvaging vehicle has a hoisting hook which enables the self forklift to move only with the front wheel as a loading wheel while raising the back wheel away from the floor surface. The self forklift is connected to the unmanned salvaging vehicle by both of the hooks. (I.S.)

    As now being explored for fusion applications confinement systems based on the mirror principle embody two kinds of plasma regimes. These two regimes are: (a) high-beta plasmas, stabilized against MHD and other low frequency plasma instabilities by magnetic-well fields, but characterized by non-Maxwellian ion distributions; (b) near-Maxwellian plasmas, confined electrostatically (as in the tandem mirror) or in a field-reversed region within the mirror cell. Common to both situations are the questions of anomalous transport owing to high frequency instabilities in the non-maxwellian portions of the plasmas. This report will summarize the status of theory and of experimental data bearing on these questions, with particular reference to the high temperature regimes of interest for fusion power

The resulting model of sediment transport, as obtained by numerical modelling from the refraction diagrams, taking into consideration the angle of approach and waves heights along the 10-m isobath, was capable of reproducing the patterns of sediment dispersion provided by geomorphic indicators of the longshore drift. All this coastal region, approximately 900 km in length, is characterized by a significant divergence zone in the direction of net longshore drift of sediments, the potential intensity of which increases considerably in value, in almost its entire length, continuously toward downdrift, which might explain the greater or lesser long term susceptibility to erosion, during the Quaternary, along the coastal stretch studied.Utilizando-se as direções médias das principais frentes-de-onda que se aproximam do trecho costeiro do nordeste brasileiro compreendido entre as localidades de Rio Real (Sergipe e Galinhos (Rio Grande do Norte - coincidentes com aquelas dos principais ventos que ocorrem na área - e de seus períodos, nós definimos um modelo de clima de ondas baseado na construção de diagramas de refração. O modelo resultante de transporte de sedimentos, obtido por modelagem numérica feita a partir dos diagramas de refração, considerando o ângulo de aproximação e a altura das ondas ao longo da isóbata de 10m, foi capaz de reproduzir os padrões de dispersão de sedimentos fornecidos pelos indicadores geomórficos de deriva litorânea.

The following documents were consulted: Statute of CAPES, through Decree No. 7692 of March 2, 2012; Ordinance No. 47 of 17/10/1995; Opinion 977 1965 Newton Sucupira; Area Document of Medicine III; Interministerial Ordinance 251 of 2012, based on Decree No. 7642 of 2011 of the Ministry of Science and Technology; CAPES Regiment. The Brazilian Postgraduate system is divided in two different fields, according to its aspects: the "lato sensu" postgraduate, defined as all professional studies performed after the high school graduation; and the "stricto sensu" postgraduate that includes the master degree and the doctorate, both of them different from what is known as MSc or MS and PhD. The Brazilian doctorate is recognized as academic because its purposes include to improve the scientific and the teaching levels of university docents. The master degree has two different objectives one is to be academic and similar to the doctorate; the other is to upgrade professionals to a higher level than specialist or MBA and is denominated professional master degree. The master degrees and the doctorate are designated as courses and may be put together in a structure known as stricto sensu postgraduate program. The complexity of these courses and programs in all the areas of the superior human knowledge requires a large number of professional directly involved with this system and other professionals that attend them, called consultants and advisors. The consultants are counselors, and the advisors are assistants, both of them legally established with the incumbency to aid the postgraduate staff in all their duties. Nothing prevents a person from being a consultant on the situation and advisor on another, even in the same institution. Have knowledge about what being a consultant and advisor is required to exercise the function

    Full Text Available The aim of this study was to analyze the role of teaching at primary healthcare services within the Brazilian National Health System (SUS in dentists' training, at a public university in the south of Brazil. A qualitative methodological approach (case study was used. Interviews were conducted with 12 dentistry students, six dentists who were preceptors working in public primary healthcare services and three teachers connected with this curricular training. Our findings showed that the curricular training in SUS primary healthcare services had an impact on the dentists' education through establishment of bonds, autonomy in problem-solving and multiprofessional teamwork. It was seen that they learned about how healthcare services function, about healthcare and about development of cultural competence. There is a need to maintain constant questioning regarding these practices, and to ensure the presence of infrastructure and qualified professionals for teaching at these services.

    Full Text Available Purpose. To demonstrate feasibility of the proposed integrated optimization of various MTS parameters to reduce capital investments as well as decrease any operational and maintenance expense. This will make use of MTS reasonable. At present, the Maglev Transport Systems (MTS for High-Speed Ground Transportation (HSGT almost do not apply. Significant capital investments, high operational and maintenance costs are the main reasons why Maglev Transport Systems (MTS are hardly currently used for the High-Speed Ground Transportation (HSGT. Therefore, this article justifies use of Theory of Complex Optimization of Transport (TCOT, developed by one of the co-authors, to reduce MTS costs. Methodology. According to TCOT, authors developed an abstract model of the generalized transport system (AMSTG. This model mathematically determines the optimal balance between all components of the system and thus provides the ultimate adaptation of any transport systems to the conditions of its application. To identify areas for effective use of MTS, by TCOT, the authors developed a dynamic model of distribution and expansion of spheres of effective use of transport systems (DMRRSEPTS. Based on this model, the most efficient transport system was selected for each individual track. The main estimated criterion at determination of efficiency of application of MTS is the size of the specific transportation tariff received from calculation of payback of total given expenses to a standard payback period or term of granting the credit. Findings. The completed multiple calculations of four types of MTS: TRANSRAPID, MLX01, TRANSMAG and TRANSPROGRESS demonstrated efficiency of the integrated optimization of the parameters of such systems. This research made possible expending the scope of effective usage of MTS in about 2 times. The achieved results were presented at many international conferences in Germany, Switzerland, United States, China, Ukraine, etc. Using MTS as an

    The retaking of the ethanol program in the year 2003 as a fuel for light road transportation in Brazil through the introduction of flex fuel vehicles fleet was a good strategy to overcome the difficulties of the ethanol production sector and did work to increase its market share relative to gasoline. This process, however, may cause a future disequilibrium on the food production and on the refining oil derivates structure. In order to analyze the substitution process resultant of the competition between two opponents fighting for the same market, in this case the gasoline/ethanol substitution process, a method derived from the biomathematics based on the non-linear differential equations (NLDE) system is utilized. A brief description of the method is presented. Numerical adherence of the method to explain several substitution phenomena that occurred in the past is presented in the previous author's paper, in which the urban gas pipeline system substitution of bottled LPG in the dwelling sector and the substitution of the urban diesel transportation fleet by compressed natural gas (CNG) buses is presented. The proposed method is particularly suitable for prospective analysis and scenarios assessment. (author)

    1997-01-01

    Because of the need to perform comparisons between transportation systems that are likely to have significantly different levels of risk, both because of differing degrees of freedom in achieving desired performance levels and their different states of development and utilization, an approach has been developed for performing early comparisons of transportation architectures explicitly taking into account quantitative measures of uncertainty and resulting risk. The approach considers the uncertainty associated with the achievement of technology goals, the effect that the achieved level of technology will have on transportation system performance and the relationship between transportation system performance/capability and the ability to accommodate variations in payload mass. The consequences of system performance are developed in terms of expected values and associated standard deviations of nonrecurring, recurring and the present value of transportation system life cycle cost. Typical results are presented to illustrate the application of the methodology.

Information communication technologies have gained increasing attention and importance in modern transportation systems. Automotive manufacturers are developing in-vehicle sensors and their applications in different areas including safety, traffic management, and infotainment. Government institutions are implementing roadside infrastructures such as cameras and sensors to collect data about environmental and traffic conditions. By seamlessly integrating vehicles and sensing devices, their sensing and communication capabilities can be leveraged to achieve smart and intelligent transportation systems. We discuss how sensor technology can be integrated with the transportation infrastructure to achieve a sustainable Intelligent Transportation System (ITS) and how safety, traffic control and infotainment applications can benefit from multiple sensors deployed in different elements of an ITS. Finally, we discuss some of the challenges that need to be addressed to enable a fully operational and cooperative ITS environment.

    2005-05-01

    The Southern Brazilian Shelf (SBS) is one of the most productive fishing areas in the Southwestern Atlantic. Eggs and larvae of about 88 fish species distributed among 48 families occur in the plankton community in this area. The processes involving the circulation in this area and its influence on eggs/larvae transport are poorly understood. Recent studies described the spawning activity of anchovy relating it to oceanographic processes. These studies suggest that the predominant onshore Ekman transport, which occurs mainly in the winter and spring periods, keeps the eggs and larvae in coastal areas. It is also known that the continental runoff is a primary factor to the formation of a retention zone for planktonic organisms over the SBS. The formation of a stagnant zone, where the residual currents are weak, favors the patchiness character of plankton communities and nutrients. In our ongoing study we investigate with data and model the dispersion pattern of eggs/larvae of Engraulis anchoita in this region, considering both biological and physical processes. In the modelling approach, surface velocity fields from runs with the Princeton Ocean Model (POM) are used as input data for an Individual Based Model (IBM). This IBM treats every single particle as an individual with its own features, tracking particles (eggs/larvae) trajectories using a Runge-Kutta scheme for spatial interpolation. The analyses of our preliminary results seems to confirm the expected pattern in which the majority of eggs and larvae are transported to their nursery grounds, remaining in these areas.

    1993-01-01

    When developing a transportation system to transport transuranic (TRU) waste from ten widely-dispersed generator sites, the Department of Energy (DOE) recognized and addressed many challenges. Shipments of waste to the Waste Isolation Pilot Plant (WIPP) were to cover a twenty-five year period and utilize routes covering over twelve thousand miles in twenty-three states. Enhancing public safety by maximizing the payload, thus reducing the number of shipments, was the primary objective. To preclude the requirement for overweight permits, the DOE started with a total shipment weight limit of 80,000 pounds and developed an integrated transportation system consisting of a Type ''B'' package to transport the material, a lightweight tractor and trailer, stringent driver requirements, and a shipment tracking system referred to as ''TRANSCOM''

    2005-01-01

    One challenge of modern biology is to be able to match genes and their encoded proteins with events at the molecular, cellular, tissue, and organism levels, and thus, provide a multi-level understanding of gene function and dysfunction. How well this can be done for xenobiotic transporters depends on a knowledge of the genes expressed in the tissue, the cellular locations of the gene products (do they function for uptake or efflux?), and our ability to match substrates with transporters using information obtained from cloned transporters functioning in heterologous expression systems. Clearly, making a rational choice of expression system to use for the characterization and study of cloned xenobiotic transporters is a critical part of study design. This choice requires well-defined goals, as well as an understanding of the strengths and weaknesses of candidate expression systems

    The concentration and biomarker compositions of sedimentary organic matter (OM) as well as fine and coarse suspended particles were analysed to identify the impact of deforestation on the transport of terrigenous organic matter (OM) in the Rio Tapajos, a major tributary to the Amazon. Substantial shifts in the concentration and composition of recently deposited sedimentary OM suggest that intensive deforestation over the last few decades has considerably modified the natural inputs of sedimentary materials to the aquatic ecosystems by disrupting the terrigenous fluxes of humus and soil and materials from the drainage basin. The observed compositional changes of bulk OM and land derived biomarkers (e.g. lignin) in recent sediments illustrate a sedimentary enrichment in OM from soil horizons that, under normal forest cover, tend to be retained in the drainage basin. On average, the recently accumulated OM is nitrogen-rich ((C/N)a=12-15) and more highly degraded ((Ac/Al)v=0.4-0.6 and DHBA/V=0.15-0.20) than deep materials ((C/N)a=20-30, (Ac/Al)v=0.25-0.4, and DHBA/V=0.05-0.10), showing that this recently accumulated material is more humified than original inputs to the aquatic system, and consistent with increased exportation if fine eroded mineral and organic particles from surface soils along river banks. The present study illustrates the relevance of using OM oxidation products in sediment profiles to evaluate deforestation impacts on aquatic ecosystems and to characterize the nature of eroded soil materials, complementing studies on mineral/metal cycling.

    A fully mechanistic model based on diffusion equations for gas transport in a flooded rice system is presented. The model has transport descriptions for various compartments in the water-saturated soil and within the plant. Plant parameters were estimated from published data and experiments independent of the validation experiment. An independent experiment is described in which the diffusion coefficient of sulfurhexafluoride (SF6) in water-saturated soil was determined. The model was validated by experiments in which transport of SF6 through soil and plant was monitored continuously by photoacoustics. The independent default settings could reasonably predict gas release dynamics in the soil-plant system. Calculated transmissivities and concentration gradients at the default settings show that transport within the soil was the most limiting step in this system, which explains why most gases are released via plant-mediated transport. The root-shoot interface represents the major resistance for gas transport within the plant. A sensitivity analysis of the model showed that gas transport in such a system is highly sensitive to the estimation of the diffusion coefficient of SF6, which helps to understand diel patterns found for greenhouse gas emissions, and to the root distribution with depth. This can be understood from the calculated transmissivities. The model is less sensitive to changes in the resistance at the root-shoot interface and in the root fraction active in gas exchange. The model thus provides an understanding of limiting steps in gas transport, but quantitative predictions of in situ gas transport rates will be difficult given the plasticity of root distribution.

    This study presents an application of a performance-based approach to definition of requirements, design and evaluation of physical protection systems for nuclear facilities. Such approach considers a probabilistic analysis of the threat, equipment, systems and response forces used to prevent, dissuade and detain malicious acts against the integrity of facilities and the nuclear materials inside them. Nowadays, in the context of Brazilian nuclear facilities licensing, a mostly prescriptive approach is adopted, which despite having advantages such as simplified inspections and homogeneous regulatory requisites amid different fuel cycle facility types, does not consider evolution, dynamism and capacities of external or internal threats to facilities and to Brazilian Nuclear Program itself, neither provides metrics to evaluate system performance facing such threats. In order to preserve actual plans and systems confidentiality, a facility hypothetical model is created, including a research reactor and a waste storage facility. It is expected that the methodology and results obtained in this study serve in the future as a basis to Brazilian nuclear operators, in elaboration process of their Physical Protection Plans, which must comply with future regulation CNEN-NN 2.01, a revision of CNEN-NE 2.01, once that regulation will include performance requisites.

    1991-01-01

    The Department of Energy (DOE) has developed an integrated transportation system to transport transuranic (TRU) waste from ten widely-dispersed generator sites to the Waste Isolation Pilot Plant (WIPP). The system consists of a Type B container, a specially-designed trailer, a lightweight tractor, the DOE ''TRANSCOM'' vehicle tracing system, and uniquely qualified and highly-trained drivers. In June of 1989, the National Academy of Sciences reviewed the transportation system and concluded that: ''The system proposed for transportation of TRU waste to WIPP is safer than that employed for any other hazardous material in the United States today and will reduce risk to very low levels.'' The next challenge facing the DOE was demonstrating that this system was ready to transport the TRU waste to the WIPP site in the safest manner possible. Not only did the DOE feel that it was necessary to convince itself that the system was safe, but also representatives of the 23 states through which it traveled

    Economy of scale is considered to enhance competitiveness of nuclear energy for electricity generation but only when high capacity factors are considered. This study shows that for the brazilian electricity generation system low capacity factors are expected and economy of scale has to be considered against the size of the Nuclear program. Units of 600 MW are competitive both for small and large Programs. (author)

  5. The “corruption” of the Criminal System: the Brazilian case

    Full Text Available We seek, in this article, from a sociological analysis of criminal law, to reflect on how social exclusion influences the very configuration of the crime and the criminal. Our hypothesis, based on the Systems Theory of Niklas Luhmann, is that there is, especially in the so-called “periphery” of modernity, a ‘corruption’ of the criminal system, in that it operates with distinctions that are alien to it, including only people who are excluded from other social sub-systems. We base the research on official data on the Brazilian criminal and penitentiary system, these data corroborating the impressions derived from field research.

    Sergio Miranda Freire

    Full Text Available AbstractIntroductionThis paper's aim is to develop a data warehouse from the integration of the files of three Brazilian health information systems concerned with the production of ambulatory and hospital procedures for cancer care, and cancer mortality. These systems do not have a unique patient identification, which makes their integration difficult even within a single system.MethodsData from the Brazilian Public Hospital Information System (SIH-SUS, the Oncology Module for the Outpatient Information System (APAC-ONCO and the Mortality Information System (SIM for the State of Rio de Janeiro, in the period from January 2000 to December 2004 were used. Each of the systems has the monthly data production compiled in dbase files (dbf. All the files pertaining to the same system were then read into a corresponding table in a MySQL Server 5.1. The SIH-SUS and APAC-ONCO tables were linked internally and with one another through record linkage methods. The APAC-ONCO table was linked to the SIM table. Afterwards a data warehouse was built using Pentaho and the MySQL database management system.ResultsThe sensitivities and specificities of the linkage processes were above 95% and close to 100% respectively. The data warehouse provided several analytical views that are accessed through the Pentaho Schema Workbench.ConclusionThis study presented a proposal for the integration of Brazilian Health Systems to support the building of data warehouses and provide information beyond those currently available with the individual systems.

  8. Not planning a sustainable transport system

    The overall objective of the Swedish transport policy is to ensure the economically efficient and sustainable provision of transport services for people and business throughout the country. More specifically, the transport sector shall, among other things, contribute to the achievement of environmental quality objectives in which the development of the transport system plays an important role in the achievement of the objectives. The aim of this study is to analyse if current transport planning supports this policy. This is done by analysing two recent cases: the National Infrastructure Plan 2010–2021, and the planning of Bypass Stockholm, a major road investment. Our results show that the plans are in conflict with several of the environmental quality objectives. Another interesting aspect of the planning processes is that the long-term climate goals are not included in the planning processes, neither as a clear goal nor as factor that will influence future transport systems. In this way, the long-term sustainability aspects are not present in the planning. We conclude that the two cases do not contribute to a sustainable transport system. Thus, several changes must be made in the processes, including putting up clear targets for emissions. Also, the methodology for the environmental assessments needs to be further developed and discussed. - Highlights: • Two cases are studied to analyse if current planning supports a sustainable transport system. • Results show that the plans are in conflict with several of the environmental quality objectives. • Long-term climate goals are not included in the planning processes. • Current practices do not contribute to a sustainable planning processes. • Methodology and process for environmental assessments must be further developed and discussed

  9. An attempt to link the Brazilian Height System to a World Height System

    Directory of Open Access Journals (Sweden)

    V. G. Ferreira

    Full Text Available This paper deals with the geopotential approach to investigate the present Brazilian Height System (BHS. Geopotential numbers are derived from Global Positioning System (GPS satellite surveying and disturbing potential on selected benchmarks. A model for the disturbing potential can be obtained by an existing set of spherical harmonic coefficients such as the Earth Gravity Model 2008 (EGM08. The approach provides absolute evaluation of local normal geopotential numbers (aka spheropotential numbers related to a so-called World Height System (WHS. To test the validity of the proposed methodology, a numerical experiment was carried out related to a test region in Southern Brazil. The accuracy of the derived geopotential numbers was tested versus local normal geopotential numbers based on 262 GPS/leveling points. The root mean square error (RMSE value for metric offset of BHS derived from geopotential numbers and the disturbing potential modeling in the test area was estimated to be near 0.224 meters in the absolute view. Therefore, since these spheropotential numbers are referred to a local datum, these results of comparisons may be an indicator of the mean bias of local network due to the effect of local Sea Surface Topography (SSTop and possible offset between the unknown reference for the BHS and the quasigeoid model in the region.

    1995-12-31

    Several options can be envisaged in order to alleviate the external costs of modern transport systems: moral conviction, strict regulations (including enforcement), user charge principles (e.g. road pricing, Pigovian taxation), sophisticated environment-friendly technologies (e.g. route guidance, zero-emission cars) and alternative modes of physical planning (e.g. compact city design). Any reduction target in environmental stress has to be assessed from both an environmental sustainability viewpoint and from a cost effectiveness viewpoint. Such an assessment may be based on evaluation criteria that are internal to the transport system or on criteria that mirror an overall systemic efficiency and sustainability. This provokes the question of the most appropriate level of reduction of environmental pollution by the transport sector compared to other economic sectors. A policy strategy aiming at a more sustainable transport system has to identify quantitative criteria which would offer guidelines on the maximum allowable contribution to environmental degradation by the transport sector. This presupposes knowledge on the total permissible pollution in a given area and in a given time frame, as well as knowledge on the share of the transport system in this total volume of pollution (for different pollutants). The aim of this paper is to develop some thoughts on the question of identifying the maximum allowable pollution share by the transport sector, assuming a critical level of maximum resource use, a maximum carrying capacity, a maximum environmental utilisation space, a maximum sustainable yield or some other critical threshold level for environmental decay. The notion of maximum environmental capacity use (MECU) is used to indicate the maximum resource use of a given environmental capital stock that - in a given time period - is compatible with both socio-economic objectives and environmental quality conditions now and in the future. 6 tabs., 24 refs.

  13. Technological and Productive Density in Sectoral Innovation Systems: The Case of the Brazilian Aeronautics Industry

    Directory of Open Access Journals (Sweden)

    Marcio da Silveira Luz

    2011-11-01

    Full Text Available This article discusses whether a globally competitive high-tech firm is sustainable without being associated with a sufficiently dense sectoral innovation system. It focuses on Embraer and hence on the Brazilian aeronautics industry. Despite not benefiting from a highly subsidized process for technological and financial modernization, Embraer has become the world’s third-ranking producer of commercial jets thanks to institutional innovations, especially in producing and managing contracts with suppliers and risk-sharing partners. The conclusion drawn is that the competitiveness of the Brazilian aircraft industry depends on the continuing supply of technology in international markets. Technological restrictions imposed for geopolitical reasons, or even for market constraints, could fatally undermine the strategy adopted by the company.

  14. Morpho-anatomical features of underground systems in six Asteraceae species from the Brazilian Cerrado.

    Appezzato-da-Glória, Beatriz; Cury, Graziela

    2011-09-01

    In the Brazilian Cerrado (neotropical savanna), the development of bud-bearing underground systems as adaptive structures to fire and dry periods can comprise an important source of buds for this ecosystem, as already demonstrated in the Brazilian Campos grasslands and North American prairies. Asteraceae species from both woody and herbaceous strata have subterranean organs that accumulate carbohydrates, reinforcing the adaptive strategy of these plants to different environmental conditions. This study aims to analyse the morpho-anatomy of underground systems of six species of Asteraceae (Mikania cordifolia L.f. Willd., Mikania sessilifolia DC, Trixis nobilis (Vell.) Katinas, Pterocaulon alopecuroides (Lam.) DC., Vernonia elegans Gardner and Vernonia megapotamica Spreng.), to describe these structures and to verify the occurrence and origin of shoot buds, and to analyse the presence of reserve substances. Individuals sampled in Cerrado areas in São Paulo State showed thick underground bud-bearing organs, with adventitious or lateral roots and presence of fructans. Xylopodium was found in all studied species, except for Trixis nobilis, which had stem tuber. The presence of fructans as reserve, and the capacity of structures in the formation of buds indicate the potential of herbaceous species of Asteraceae in forming a viable bud bank for vegetation regeneration in the Brazilian Cerrado.

    The Cryomodules (CM) for the Linear Coherent Light Source II (LCLS-II) will be shipped to SLAC (Menlo Park, California) from JLab (Newport News, Virginia) and FNAL (Batavia, Illinois). A transportation system has been designed and built to safely transport the CMs over the road. It uses an array of helical isolator springs to attenuate shocks on the CM to below 1.5g in all directions. The system rides on trailers equipped with Air-Ride suspension, which attenuates vibration loads. The prototype LCLS-II CM (pCM) was driven 750 miles to test the transport system; shock loggers recorded the shock attenuation on the pCM and vacuum gauges were used to detect any compromises in beamline vacuum. Alignment measurements were taken before and after the trip to check whether cavity positions had shifted beyond the ± 0.2mm spec. Passband frequencies and cavity gradients were measured at 2K at the Cryomodule Test Facility (CMTF) at JLab to identify any degradation of CM performance after transportation. The transport system was found to have safely carried the CM and is cleared to begin shipments from JLab and FNAL to SLAC.

  16. Bacterial ferrous iron transport: the Feo system.

    Science.gov (United States)

    Lau, Cheryl K Y; Krewulak, Karla D; Vogel, Hans J

    2016-03-01

    To maintain iron homeostasis within the cell, bacteria have evolved various types of iron acquisition systems. Ferric iron (Fe(3+)) is the dominant species in an oxygenated environment, while ferrous iron (Fe(2+)) is more abundant under anaerobic conditions or at low pH. For organisms that must combat oxygen limitation for their everyday survival, pathways for the uptake of ferrous iron are essential. Several bacterial ferrous iron transport systems have been described; however, only the Feo system appears to be widely distributed and is exclusively dedicated to the transport of iron. In recent years, many studies have explored the role of the FeoB and FeoA proteins in ferrous iron transport and their contribution toward bacterial virulence. The three-dimensional structures for the Feo proteins have recently been determined and provide insight into the molecular details of the transport system. A highly select group of bacteria also express the FeoC protein from the same operon. This review will provide a comprehensive look at the structural and functional aspects of the Feo system. In addition, bioinformatics analyses of the feo operon and the Feo proteins have been performed to complement our understanding of this ubiquitous bacterial uptake system, providing a new outlook for future studies. © FEMS 2015.

    2017-01-01

    Full Text Available Railway, subway, airplane, and other transportation systems have drawn an increasing interest on the use of wireless communications for critical and noncritical services to improve performance, reliability, and passengers experience. Smart transportation systems require the use of critical communications for operation and control, and wideband services can be provided using noncritical communications. High speed train (HST is one of the best test cases for the analysis of communication links and specification of the general requirements for train control and supervision, passenger communications, and onboard and infrastructure wireless sensors. In this paper, we analyze in detail critical and noncritical networks mainly using the HST as a test case. First, the different types of links for smart rail transportation are described, specifying the main requirements of the transportation systems, communications, and their applications for different services. Then, we propose a network architecture and requirements of the communication technologies for critical and noncritical data. Finally, an analysis is made for the future technologies, including the fifth-generation (5G communications, millimeter wave (mmWave, terahertz (THz, and satellites for critical and high-capacity communications in transportation.

    2011-04-01

    Full Text Available In geophysics and seismology, raw data need to be processed to generate useful information that can be turned into knowledge by researchers. The number of sensors that are acquiring raw data is increasing rapidly. Without good data management systems, more time can be spent in querying and preparing datasets for analyses than in acquiring raw data. Also, a lot of good quality data acquired at great effort can be lost forever if they are not correctly stored. Local and international cooperation will probably be reduced, and a lot of data will never become scientific knowledge. For this reason, the Seismological Laboratory of the Institute of Astronomy, Geophysics and Atmospheric Sciences at the University of São Paulo (IAG-USP has concentrated fully on its data management system. This report describes the efforts of the IAG-USP to set up a seismology data management system to facilitate local and international cooperation.

    To evaluate the transport of children in automobiles and the use of child restraints systems (CRS). This is a transversal descriptive study which included 200 vehicle drivers who carried 0-10 year old children in the city of São Luis, MA, Brazil. The drivers' passengers' and children's features were properly identified. The children's transportation using CRS were analyzed according to the Resolution 277/8 of the Brazilian National Traffic Department. The transportation of children was classified as inappropriate in 70.5% of the vehicles analyzed. The most common way for children transportation was free on the back seats (47%) or on the lap of passengers/drivers (17%). The main reasons to justify the improper transportation were either not understanding the importance of CRS use (64.5%) or not having financial resources to buy the devices. The child safety seat was the most used CRS (50.8 %) among vehicles with proper child transportation system. The transportation of children was inappropriate in most of the vehicles analyzed, reflecting the need for creating awareness among automobile drivers, including education, supervision and improvement of policies for health improvement and prevention of accidents involving children transportation.

  4. Pathogen transport in groundwater systems: contrasts with traditional solute transport

    Science.gov (United States)

    Hunt, Randall J.; Johnson, William P.

    2017-06-01

    Water quality affects many aspects of water availability, from precluding use to societal perceptions of fit-for-purpose. Pathogen source and transport processes are drivers of water quality because they have been responsible for numerous outbreaks resulting in large economic losses due to illness and, in some cases, loss of life. Outbreaks result from very small exposure (e.g., less than 20 viruses) from very strong sources (e.g., trillions of viruses shed by a single infected individual). Thus, unlike solute contaminants, an acute exposure to a very small amount of contaminated water can cause immediate adverse health effects. Similarly, pathogens are larger than solutes. Thus, interactions with surfaces and settling become important even as processes important for solutes such as diffusion become less important. These differences are articulated in "Colloid Filtration Theory", a separate branch of pore-scale transport. Consequently, understanding pathogen processes requires changes in how groundwater systems are typically characterized, where the focus is on the leading edges of plumes and preferential flow paths, even if such features move only a very small fraction of the aquifer flow. Moreover, the relatively short survival times of pathogens in the subsurface require greater attention to very fast (<10 year) flow paths. By better understanding the differences between pathogen and solute transport mechanisms discussed here, a more encompassing view of water quality and source water protection is attained. With this more holistic view and theoretical understanding, better evaluations can be made regarding drinking water vulnerability and the relation between groundwater and human health.

    Filamentous fungi in drinking water can block water pipes, can cause organoleptic biodeterioration, and are a source of pathogens. There are increasing reports of the involvement of the organisms in biofilms. This present study describes a sampling device that can be inserted directly into pipes within water distribution systems, allowing biofilm formation in situ. Calcofluor White M2R staining and fluorescent in situ hybridization with morphological analyses using epifluorescent microscopy were used to analyse biofilms for filamentous fungi, permitting direct observation of the fungi. DAPI (4',6-diamidino-2-phenylindole) was applied to detect bacteria. Filamentous fungi were detected in biofilms after 6 months on coupons exposed to raw water, decanted water and at the entrance of the water distribution system. Algae, yeast, and bacteria were also observed. The role of filamentous fungi requires further investigations.

    On January 1, 1995, Brazil was integrated to the world-wide seismic system, through the Seismological Observatory of the University of Brasilia, dedicated to detect and identify underground nuclear explosions. This is an unprecedented global effort program to conduct a seismic test of rapid data collection, distribution and processing evolving the most advanced sensors, global communications and data processing technologies. By the end of February, 49 countries were incorporated and the present test represents a first training step towards the final definition of an International Monitoring System to monitoring a Comprehensive test Band Treaty. Besides accomplishing its main goal, the global monitoring program will be able to supply rapidly, through the International Data Center, important information to the seismological community.

    Full Text Available A simulation model for evaluating the performance of a mass public-transport system (MPTS is presented in this report. The final prototype was flexible both for constructing an STPM “skeleton“ and modelling random events characteristic of this type of system. The final model was a queuing network with other elements such as origin- destination matrices and graphs allowing typical MPTS phenomena to be considered. The simulation model reacted as expected to changes in the parameters and allowed defining and evaluating typical performance measurement for queues (e.g. mean time spent in the system and queue, expected queue length as well as others representative of these systems.

    Due to environmental concerns, the Advanced Photon Source has a policy that disallows any exposed lead within the facility. This creates a real problem for the beam transport system, not so much for the pipe but for the flexible coupling (bellows) sections. A complete internally shielded x-ray transport system, consisting of long transport lines joined by flexible coupling sections, has been designed for CARS sector 14 to operate either at high vacuum or as a helium flight tube. It can effectively shield against air scattering of wiggler or undulator white beam with proper placement of apertures, collimators, and masks for direct beam control. The system makes use of male- and female-style fittings that create a labyrinth allowing for continuous shielding through the flexible coupling sections. These parts are precision machined from a ternary hypereutectic lead alloy (cast under 15 inches of head pressure to assure a pinhole-free casting) then pressed into either end (rotatable vacuum flanges) of the bellows assembly. The transport pipe itself consists of a four part construction using a stepped transition ring (Z-ring) to connect an inner tube to the vacuum flange and also to a protective and supportive outer tube. The inner tube is wrapped with 1/16 double-prime pure lead sheet to a predetermined thickness following the shape of the stepped transition ring for continuous shielding. This design has been prototyped and radiation tested. copyright 1996 American Institute of Physics

    2017-11-01

    We study transport in the stochastic Lorenz system mathematically, computationally and using a circuit model. The circuit model provides a very efficient method for computing long time averages of polynomials in the variables X , Y , and Z with real-time updates. In particular, we use this approach to the quantity , which is the heat transport corresponding with Rayleigh-Bénard convection. We interpret our results in the framework of analytical stochastic upper bounds for versus ρ (the reduced Rayleigh number), as well as against numerical solutions. For a given ρ we find a rich dependence of the transport on both noise color and amplitude due to the detailed coupling of noise with Unstable Periodic Orbits.

  15. Flexibility valuation in the Brazilian power system: A real options approach

    International Nuclear Information System (INIS)

    Marreco, Juliana de Moraes; Carpio, Lucio Guido Tapia

    2006-01-01

    This paper presents a valuation study of operational flexibility in the complex Brazilian Power System. Thermopower plants represent operational flexibility for the national system operator provided they can be dispatched in dry periods to supply part of the load when reservoir waters are too low. Deficit costs can be avoided as a result. We have adopted a real options approach to calculate the fair value of a financial subsidy to be paid to thermal generators for their availability to the system. A financial subsidy is mandatory for their economic feasibility and, therefore, for increased thermopower capacity in the Brazilian Power System. This is why this policy is currently being studied by Brazil's federal government. In order to illustrate our modeling we have run the model for the southeast subsystem. We found a flexibility value of US$4.52 billion, which represents US$497/MW per year. This means that a 100 MW thermopower plant should receive US$49,700 for each year of its economic lifetime as a fair premium incentive to investments

    Science.gov (United States)

    Pinheiro Filho, Francisco Percival; Sarti, Flávia Mori

    2012-11-01

    The principles and guidelines of the Brazilian Unified Health System (SUS) impose a healthcare service structure based on public policy networks which, combined with the financing model adopted, leads to market failings. This imposes barriers to the management of the public health system and the enactment of SUS objectives. The institutional characteristics and the heterogeneity of players, allied to the existence of different healthcare approaches, generate analytical complexity in the study of the global dynamics of the SUS network. There are limitations in the use of quantitative methods based on static analysis of retrospective SUS data. Thus, an approach taking SUS as a complex system using innovative quantitative methodology based on computational simulation is proposed. This paper sought to analyze challenges and possibilities of the combined application of cellular automata modeling and agent-based modeling for simulation of the evolution of the SUS healthcare service network. This approach should permit better understanding of the organization, heterogeneity and structural dynamics of the SUS service network and a minimization of the effects of market failings on the Brazilian health system.

    1982-01-01

    These notes are in part based on a course for advanced students in the applications of stochastic processes held in 1978 at the University of Konstanz. These notes contain the results of re­ cent studies on the stochastic description of ion transport through biological membranes. In particular, they serve as an introduction to an unified theory of fluctuations in complex biological transport systems. We emphasize that the subject of this volume is not to introduce the mathematics of stochastic processes but to present a field of theoretical biophysics in which stochastic methods are important. In the last years the study of membrane noise has become an important method in biophysics. Valuable information on the ion transport mechanisms in membranes can be obtained from noise analysis. A number of different processes such as the opening and closing of ion channels have been shown to be sources of the measured current or voltage fluctuations. Bio­ logical 'transport systems can be complex. For example, the tr...

    Holmes, Bruce J.; Durham, Michael H.; Tarry, Scott E.

    2005-01-01

    This paper summarizes both the vision and the early public-private collaborative research for the Small Aircraft Transportation System (SATS). The paper outlines an operational definition of SATS, describes how SATS conceptually differs from current air transportation capabilities, introduces four SATS operating capabilities, and explains the relation between the SATS operating capabilities and the potential for expanded air mobility. The SATS technology roadmap encompasses on-demand, widely distributed, point-to-point air mobility, through hired-pilot modes in the nearer-term, and through self-operated user modes in the farther-term. The nearer-term concept is based on aircraft and airspace technologies being developed to make the use of smaller, more widely distributed community reliever and general aviation airports and their runways more useful in more weather conditions, in commercial hired-pilot service modes. The farther-term vision is based on technical concepts that could be developed to simplify or automate many of the operational functions in the aircraft and the airspace for meeting future public transportation needs, in personally operated modes. NASA technology strategies form a roadmap between the nearer-term concept and the farther-term vision. This paper outlines a roadmap for scalable, on-demand, distributed air mobility technologies for vehicle and airspace systems. The audiences for the paper include General Aviation manufacturers, small aircraft transportation service providers, the flight training industry, airport and transportation authorities at the Federal, state and local levels, and organizations involved in planning for future National Airspace System advancements.

    To analyze results of the Horus Information System, comparing elements of this system with some international experiences. Horus is a technological innovation introduced in 2009 in the Pharmaceutical management information system of the Sistema Único de Saúde (Brazilian Unified Health System). In 2011, local managers and health professionals of 1,247 municipalities (16 states) that adhered to Horus answered questionnaires on pharmaceutical assistance in primary care and about the Horus system. This is a descriptive and exploratory study, developed with the use of quantitative and qualitative methods of research. Multivariate tools were used for data collection and interpretative support of the statistical inference and thematic analysis. The main changes identified after the implementation of this system were: improvement on technical and scientific quality control of Pharmaceutical Assistance, improvement on the supply of medications and health care; training of human resources and knowledge management; improvement on the relationship health managers/users; development in the administrative management and greater inter-state management; and improvement on the technological infrastructure. In terms of health information systems, these categories are consistent with programs and obstacles observed in international experiences. The biggest gap identified was the fact that Horus was not included in a national policy of health information systems, which is in a process of consolidation in Brazil. The national database of actions and services within the Pharmaceutical Assistance will enable the collection, analysis and dissemination of information regarding integrated pharmaceutical assistance in the Brazilian context. The Horus System is a technological innovation that enables the management of the Pharmaceutical Assistance. The national base will enable the definition and agreement on national indicators of Pharmaceutical Assistance, aiming to produce evidence of

    A systems engineering study of a lighter than air airship transportation system was conducted. The feasibility of the use of airships in hauling cargo was demonstrated. Social, legal, environmental and political factors were considered as well as the technical factors necessary to design an effective airship transportation system. In order to accomplish an effective airship transportation program two phases of implementation were recommended. Phase I would involve a fleet of rigid airships of 3.5 million cubic feet displacement capable of carrying 25 tons of cargo internal to the helium-filled gas bag. The Phase I fleet would demonstrate the economic and technical feasibility of modern-day airships while providing a training capability for the construction and operation of larger airships. The Phase II portion would be a fleet of rigid airships of 12 million cubic feet displacement capable of carrying a cargo of 100 tons a distance of 2,000 miles at a cruising speed of 60 mph. An economic analysis is given for a variety of missions for both Phase I and Phase II airships.

    Full Text Available ABSTRACT BACKGROUND Bariatric surgery has become the gold standard treatment for morbid obesity, but access to surgery remains difficult and low compliance to postoperative follow-up is common. To improve outcomes, enable access and optimize follow-up, we developed a multidisciplinary preoperative approach for bariatric surgery. OBJECTIVE To determine the impact of this program in the outcomes of bariatric surgery in the Brazilian public health system. METHODS A prospective evaluation of the individuals who underwent a preoperative multidisciplinary program for bariatric surgery and comparison of their surgical outcomes with those observed in the prospectively collected historical database of the individuals who underwent surgery before the beginning of the program. RESULTS There were 176 individuals who underwent the multidisciplinary program and 226 who did not. Individuals who underwent the program had significantly lower occurrence of the following variables: hospital stay; wound dehiscence; wound infection; pulmonary complications; anastomotic leaks; pulmonary thromboembolism; sepsis; incisional hernias; eventrations; reoperations; and mortality. Both loss of follow-up and weight loss failure were also significantly lower in the program group. CONCLUSION The adoption of a comprehensive preoperative multidisciplinary approach led to significant improvements in the postoperative outcomes and also in the compliance to the postoperative follow-up. It represents a reproducible and potentially beneficial approach within the context of the Brazilian public health system.

    1999-01-01

    The scientific understanding of key physical processes between the Sun and the Earth require simultaneous measurements from many vantage points in space. Nano-satellite technologies will enable a class of constellation missions for the NASA Space Science Sun-Earth Connections. This recent emphasis on the implementation of smaller satellites leads to a requirement for development of smaller subsystems in several areas. Key technologies under development include: advanced miniaturized chemical propulsion; miniaturized sensors; highly integrated, compact electronics; autonomous onboard and ground operations; miniatures low power tracking techniques for orbit determination; onboard RF communications capable of transmitting data to the ground from far distances; lightweight efficient solar array panels; lightweight, high output battery cells; lightweight yet strong composite materials for the nano-spacecraft and deployer-ship structures. These newer smaller systems may have higher power densities and higher thermal transport requirements than seen on previous small satellites. Furthermore, the small satellites may also have a requirement to maintain thermal control through extended earth shadows, possibly up to 8 hours long. Older thermal control technology, such as heaters, thermostats, and heat pipes, may not be sufficient to meet the requirements of these new systems. Conversely, a miniature two-phase heat transport system (Mini-HTS) such as a Capillary Pumped Loop (CPL) or Loop Heat Pipe (LBP) is a viable alternative. A Mini-HTS can provide fine temperature control, thermal diode action, and a highly efficient means of heat transfer. The Mini-HTS would have power capabilities in the range of tens of watts or less and provide thermal control over typical spacecraft ranges. The Mini-HTS would allow the internal portion of the spacecraft to be thermally isolated from the external radiator, thus protecting the internal components from extreme cold temperatures during an

    2011-05-05

    The work is devoted to the physics of graphene-based optoelectronics and arrays of Josephson junctions. The first part deals with transport in a graphene p-n junction irradiated by an electromagnetic field. The photocurrent in such device is calculated analytically and compared to those observed in the recent experiments on graphene photodetectors. It is shown that in a clean effectively one-dimensional junction the photocurrent oscillates as a function of gate voltages due to the interference between electron paths accompanied by the resonant photon absorption. The second part of the thesis is devoted to the construction of a Drude-like theory for the transport of Cooper pairs in weakly disordered Josephson networks and to finding the conductivity and the characteristic temperature of the commencement of strong localization. Also, it is shown that the low-temperature superconductor-insulator transition is necessarily of the first order in all 3D and in most 2D systems.

    2009-05-01

    Full Text Available This study aims to describe how transgender people perceive services offered by the Brazilian Public Health System (SUS. This qualitative study, using the phenomenological technique, is based on eight semi-structured interviews conducted with individuals whose gender identity and/or gender expression differs from the sex they were assigned at birth. Each interview was evaluated by two interviewers and a content analysis performed by all members of the research group. The analysis identified the following categories as having high relevance to the participants’ experiences: homophobia, receptiveness, and humanization, access to health care, and suggestions to improve the SUS. Information shared by participants emphasized their belief that health care professionals are not adequately prepared to assist transgendered individuals and that health care providers should use a more sensitive approach towards them. A recurrent theme was the need to use appropriate and socially acceptable terminology when providing health care services in order to facilitate transgendered individuals' inclusive treatment. Despite the effort of Brazilian authorities, there is a need for significant improvement in health care practices in order to comply with SUS quality standards. This study highlights the importance of qualitative investigations to improve planning and to help define public health policies with the goal of including the most vulnerable and marginalized groups of the population.

    2013-09-01

    In this paper, we make explicit the changing configurations of power relations that currently characterize the Brazilian Emergency Care System (SAMU) team in Belo Horizonte, Brazil. The SAMU is a recent innovation in Brazilian healthcare service delivery. A qualitative case study methodology was used to explore SAMU's current organizational arrangements, specifically the power relations that have developed and that demonstrate internal team struggles over space and defense of particular occupational interests. The argument advanced in this paper is that these professionals are developing their work in conditions of exposure, that is, they are always being observed by someone, and that such observational exposure provides the conditions whereby everyday emergency care practices are enacted such that practice is shaped by, as well as shapes, particular, yet recognizable power relationships. Data were collected through the observation of the SAMU's work processes and through semi-structured interviews. Research materials were analyzed using discourse analysis. In the emergency care process of work, visibility is actually embedded in the disciplinary context and can thus be analyzed as a technique applied to produce disciplined individuals through the simple mechanisms elaborated by Foucault such as hierarchical surveillance, normalizing judgment, and the examination. © 2012 John Wiley & Sons Ltd.

    2017-01-01

    Full Text Available System dynamics is an approach to analyze the behavior of complex systems, such as the productive chains, strictly considering the inherent characteristics. This approach is based on mathematical concepts of nonlinear processes developed in mathematics and physics and consolidated in engineering. The concepts inherent in this approach assists in creating a mathematical model that represents a production chain by using computer simulation. Thus, the main objective of this paper is to present the formalization of the dynamic model of assessing the sustainability of Brazilian ethanol production. We analyzed the external environment and the scenarios needed for a deeper understanding of relation of cause and effect, causal loops and diagrams of flows and stocks because of the awareness stage, with regard to understanding the problems involved, according to methodology known as design science.

    Full Text Available The ideological significance in Brazilian prison system reality, usually, fulfills a purpose only expected in criminal conviction sentencing according to deprivation of freedom. Thus, there is a misunderstandig of the rehabilitation concept withspace not your discourse of application. Because of that, the current research based on literature review method aims to achieve a constitutional reinterpretation of Brazilian criminal system andof its ideological significance, as well as analyzing a review and election of legal goods (bem jurídico that are under the protection of criminal law. The overcrowding and the lack of minimal conditions are clearly shown in INFOPENs numbers, astounding numbers, which provides us an overview of this unfortunate reality. Restructuring this system is only one of the possible solutions to this problem, and, in addition to it, a constitutional review over the entire Criminal Justice is imperious to avoid a sort of segregation that, unfortunately, might be originated by the pacifying instrument itself (the criminal law, with a critical analysis about valuating and electing the legal interests that are legally protected, as well as a new interpretation of the wrongdoing, rejecting the mere comparison between the facts and the cold text of the law once taught by the classical formalistic doctrine, bringing up a constitutional perspective, so that the criminal standards can be examined in a way that takes evaluative aspects into consideration (in a materialistic and guarantistic ways, presuming that although there is, implicitly or explicitly, an attack to the law (wrongdoing, we cant move away from the idea that the agreement must be privileged as a possibility in a matter of solving criminal issues.

    Patients with ankylosing spondylitis require a team approach from multiple professionals, various treatment modalities for continuous periods of time, and can lead to the loss of labour capacity in a young population. So, it is necessary to measure its socio-economic impact. To describe the use of public resources to treat AS in a tertiary hospital after the use of biological medications was approved for treating spondyloarthritis in the Health Public System, establishing approximate values for the direct and indirect costs of treating this illness in Brazil. 93 patients selected from the ambulatory spondyloarthritis clinic at the Hospital de Clínicas of the Federal University of Paraná between September 2011 and September 2012 had their direct costs indirect treatment costs estimation. 70 patients (75.28%) were male and 23 (24.72%) female. The mean age was 43.95 years. The disease duration was calculated based on the age of diagnosis and the mean was 8.92 years (standard deviation: 7.32); 63.44% were using anti-tumour necrotic factor drugs. Comparing male and female patients the mean Bath Ankylosing Spondylitis Disease Activity Index was 4.64 and 5.49 while the mean Bath Ankylosing Spondylitis Functional Index was 5.03 and 6.35 respectively. The Brazilian public health system's spending related to ankylosing spondylitis has increased in recent years. An important part of these costs is due to the introduction of new, more expensive health technologies, as in the case of nuclear magnetic resonance and, mainly, the incorporation of anti-tumour necrotic factor therapy into the therapeutic arsenal. The mean annual direct and indirect cost to the Brazilian public health system to treat a patient with ankylosing spondylitis, according to our findings, is US$ 23,183.56.

  18. The Double-entry Bookkeeping Committee of 1914 and the Brazilian Public Accounting System

    Directory of Open Access Journals (Sweden)

    Tiago Villac Adde

    2014-12-01

    Full Text Available The history of Brazilian accounting has not been explored at length. Through a historical survey, this article presents the history of the Double-entry Bookkeeping Committee of 1914. After the Proclamation of the Republic was announced in 1889, the government started to expand its administrative bodies, necessitating the introduction of a bureaucracy able to perform new functions. In the same period, Brazil experienced a strong economic development with the development of its coffee industry. In 1905, under the leadership of Carlos de Carvalho, São Paulo State Treasury bookkeeping tasks were introduced under a double-entry bookkeeping system and through accrual and financial accounting. Double-entry bookkeeping practices in the federal public accounting system, although enshrined in law since 1808, were only fully realized after the creation of the Double-entry Bookkeeping Committee in 1914. In that same year, due to the negotiation of a second funding loan, English creditor bank auditors requested a balance of the National Treasury from the Minister of Finance Rivadávia Corrêa. Because the balance had not been prepared in eight years, the Double-entry Bookkeeping Committee was established in June of 1914, and this body completed a technical audit of Revenues and Expenditures. The committee also conducted the state administration's first Asset and Liability audit since the colonial era. The Double-entry Bookkeeping Committee of 1914 spearheaded changes to the Brazilian public accounting system, including the creation of the Public Accounting Code in 1922 and the approval of Central Accounting Office of the Republic regulation in 1924, strengthening and ascribing perpetuity to practices adopted after 1914.

    2016-09-01

    Full Text Available This paper examines the role of inventory and transportation in the supply system of parts adopted by most of the Brazilian automotive companies to feed their assembly lines. It is a system for programmed collection of pieces called Milk Run that aims, within a window of time, to collect parts from suppliers, fulfilling established routes in order to minimize the cost of transport operations and reducing inventory in the supply chain. Milk Run, a scheduled collection system of parts can be carried out by automotive industry itself: the automaker manage the best route for its collector vehicle, determining the quantity of parts required to collect at each supplier within a given route, aiming to best utilize the capacity of the vehicle. Another way to work within the Milk Run system is the automaker to find the best routing and determines the amount of parts needed to be collected from each supplier on each trip. The collection, however, is held by a third carrier. As a third way of working, the assembler can determine the quantity of parts to collect and when it will require them. A logistics carrier determines the best routing for the collection of pieces in order to meet the production plan so that there is not a lack of parts or components on the assembly line, which would lead to a stop. In this case, the logistics carrier transports parts on its own fleet of vehicles or transfer the transport operation to a carrier.

    2016-08-01

    The article presents the results of a study of road safety indicators that influence the development and operation of the transport system. Road safety is considered as a continuous process of risk management. Authors constructed a model that relates the social risks of a major road safety indicator - the level of motorization. The model gives a fairly accurate assessment of the level of social risk for any given level of motorization. Authors calculated the dependence of the level of socio-economic costs of accidents and injured people in them. The applicability of the concept of socio-economic damage is caused by the presence of a linear relationship between the natural and economic indicators damage from accidents. The optimization of social risk is reduced to finding the extremum of the objective function that characterizes the economic effect of the implementation of measures to improve safety. The calculations make it possible to maximize the net present value, depending on the costs of improving road safety, taking into account socio-economic damage caused by accidents. The proposed econometric models make it possible to quantify the efficiency of the transportation system, allow to simulate the change in road safety indicators.

    An exemplary sensor system for a fuel transport vehicle can comprise a fuel marker sensor positioned between a fuel storage chamber of the vehicle and an access valve for the fuel storage chamber of the vehicle. The fuel marker sensor can be configured to measure one or more characteristics of one or more fuel markers present in the fuel adjacent the sensor, such as when the marked fuel is unloaded at a retail station. The one or more characteristics can comprise concentration and/or identity of the one or more fuel markers in the fuel. Based on the measured characteristics of the one or more fuel markers, the sensor system can identify the fuel and/or can determine whether the fuel has been adulterated after the marked fuel was last measured, such as when the marked fuel was loaded into the vehicle.

    Full Text Available The transport properties of various systems are studied here in the context of three different models. These are: - the disordered Hubbard model applicable to correlated binary alloys with a general disorder, - the Anderson model used in describing the Kondo physics of a quantum dot connected to the external superconducting leads, and - the Ranninger-Robaszkiewicz model applied to the study of optical properties of the system with preformed electron pairs above the temperature of transition to the superconducting state. We calculate the density of states, specific heat, the Wilson ratio and conductivity of the correlated binary alloy with off-diagonal disorder. We investigate the conditions under which the Kondo peak appears in the density of states and in the conductance of a dot coupled to the external superconducting leads. We analyze the effect of the pseudogap on the optical spectra in the high temperature superconductors described by the boson-fermion model.

    This developmental effort clearly shows that a Road Transportable Analytical Laboratory System is a worthwhile and achievable goal. The RTAL is designed to fully analyze (radioanalytes, and organic and inorganic chemical analytes) 20 samples per day at the highest levels of quality assurance and quality control. It dramatically reduces the turnaround time for environmental sample analysis from 45 days (at a central commercial laboratory) to 1 day. At the same time each RTAL system will save the DOE over $12 million per year in sample analysis costs compared to the costs at a central commercial laboratory. If RTAL systems were used at the eight largest DOE facilities (at Hanford, Savannah River, Fernald, Oak Ridge, Idaho, Rocky Flats, Los Alamos, and the Nevada Test Site), the annual savings would be $96,589,000. The DOE`s internal study of sample analysis needs projects 130,000 environmental samples requiring analysis in FY 1994, clearly supporting the need for the RTAL system. The cost and time savings achievable with the RTAL system will accelerate and improve the efficiency of cleanup and remediation operations throughout the DOE complex.

  10. Calculating iron transport in nuclear systems

    International Nuclear Information System (INIS)

    Horowitz, J.S.; Merilo, M.; Munson, D.

    2002-01-01

    The presence of high levels of iron in the final feedwater of nuclear plants is undesirable and can have a significant contribution to plant operations and maintenance (O and M) costs. A number of options are available to reduce the iron concentration, but tend to be expensive. Recently a method was developed to quantitatively determine the contribution of each iron source, such that reduction options can be quantitatively compared. The method is based on industry experience that the majority of iron has been released by flow-accelerated corrosion (FAC). FAC is one of the most predictable forms of corrosion and a well-developed predictive model has been developed and also encoded in the CHECWORKS. A combination of CHECWORKS and supplemental calculations have been used to model the iron transport in a number of US BWRs and PWRs. The iron generated by FAC in all the normally operating piping systems has been calculated using the results of CHECWORKS predictions and a special post processor. The post processor accounts for the differences between the maximum corrosion rate calculated by CHECWORKS and the average corrosion (iron generation) rate for a pipe-fitting or length of pipe. It also calculates the amount of iron generated within the fitting or pipe. Supplemental calculations have been used to determine the iron generation from the major, in-line components - high and low pressure turbines, moisture separators, feedwater heaters and the condenser. All of the iron generation rates for the equipment and piping were appropriately summed and iron concentrations estimated throughout the steam-feedwater system. Predicted iron concentrations have agreed well with plant measurements. The availability of specific iron generation rates allows plant management to make reasoned decisions about the countermeasures to deal with iron generation and transport. The countermeasures that have been examined to reduce the amount of iron transport include installing additional water

  11. Picosecond excitation transport in disordered systems

    1987-11-01

    Time-resolved fluorescence decay profiles are used to study excitation transport in 2- and 3-dimensional disordered systems. Time-correlated single photon counting detection is used to collect the fluorescence depolarization data. The high signal-to-noise ratios afforded by this technique makes it possible to critically examine current theories of excitation transport. Care has been taken to eliminate or account for the experimental artifacts common to this type of study. Solutions of 3,3'-diethyloxadicarbocyanine iodide (DODCI) in glycerol serve as a radomly distributed array of energy donors in 3-dimensions. A very thin sample cell (/approximately/ 2 μm) is used to minimize the effects of fluorescence self-absorption on the decay kinetics. Evidence of a dynamic shift of the fluorescence spectrum of DODCI in glycerol due to solvent reorganization is presented. The effects of excitation trapping on the decay profiles is minimized in the data analysis procedure. The 3-body theory of Gochanour, Andersen, and Fayer (GAF) and the far less complex 2-particle analytic theory of Huber, Hamilton, and Barnett yield indistinguishable fits to the data over the wide dynamic range of concentrations and decay times studied

    Electric vehicles (EVs) are being developed and considered as the future transportation to reduce emission of toxic gas, cost and weight. The battery pack is one of the main crucial parts of the electric vehicle. The power optimization of the battery pack has been maintained by developing a two phase evaporative thermal management system which operation has been controlled by using a wireless battery management system. A large number of individual cells in a battery pack have many wire terminations that are liable for safety failure. To reduce the wiring problem, a wireless battery management system based on ZigBee communication protocol and point-to-point wireless topology has been presented. Microcontrollers and wireless modules are employed to process the information from several sensors (voltage, temperature and SOC) and transmit to the display devices respectively. The WBMS multistage charge balancing system offering more effective and efficient responses for several numbers of series connected battery cells. The concept of double tier switched capacitor converter and resonant switched capacitor converter is used for reducing the charge balancing time of the cells. The balancing result for 2 cells and 16 cells are improved by 15.12% and 25.3% respectively. The balancing results are poised to become better when the battery cells are increased.

    The Law 10.233/2001 of 2001 designated the National Agency of Land Transportation (ANTT) as responsible for the gathering and organizing of information about Brazilian pipeline infrastructure. In order to fulfill this legal requirement, ANTT is developing the Brazilian Pipeline Catalog System (SISDUT) and is creating a geo referenced database. The priority is to collect information on the critical points, those where the pipelines intersect with road and rail networks. The SISDUT geo processing catalog will store all information required to manage and track critical points, such as: technical construction standards, as built plans, adjustments terms with roads and rail networks, special usage grants, inspection procedures, pictures taken on local visits, ANTT deliberations, usage of soil, etc. The system was designed using the Object Oriented Analysis and Design paradigms, modeled in the Unified Modeling Language. The database will be populated by ANTT and with data imported from partners. The queries for literal and geographic data will be available on the Internet using Web mapping. SISDUT system will allow spatial cross referencing among its many entities, allowing complex analysis and tracking of events in the critical points. (author)

    2015-01-01

    Full Text Available The paper describes a conception of intelligent transport systems and reveals their benefit in solution of various tasks: road traffic safety, speed increase, ecology improvement, relief of urban territories, comfort improvement and others. The intelligent transport systems cover all types of transport and consider all the elements of transportation system: transport facilities, infrastructure, dynamically interаctive drivers or users. The information is considered as a basis of the intelligent transport systems, whether we have statistic or operational transportation data or a digital map. Data obtained with the help of such systems can provide real-time information on current situation in the network or on-line information in order to plan a road trip. In addition to the mentioned capabilities of the intelligent transport systems in respect of solution of modern transport problems the paper considers comfort factors and also their technologies, logical and physical architecture, productivity and operational efficiency.The paper provides an analysis on the development of the intelligent transport systems in the world: the USA, European Union and Russia. The initial stage for creation of the intelligent transport systems has been characterized with due account of the experience of various countries. The paper describes myths and realities pertaining to formation of such systems in the countries with transition economy. Peculiar features concerning development of the intelligent transport systems in Belarus have been analyzed in the paper. The paper presents recommendations on practical steps for establishing the Belarusian intelligent transport system. The main problem in creation of the intelligent transport systems is not technical issue but an institutional one. It is necessary to combine efforts of state, research, industrial, commercial, academic structures in the united team.

    2013-03-01

    Full Text Available Conventional tillage (CT and no-tillage (NT management systems alter soil nutrient availability and consequently modify soil microbial response to nutrient additions such as carbon (C and phosphorus (P. The objective of this study is to evaluate microbial response to the addition of C (glucose and P (Na2HPO4.7H2O under CT and NT in the brazilian Cerrado. In response to glucose addition, the NT system yielded higher microbial respiration rates and glucose consumption than the CT system. The best microbial response to C addition was after 0 - 12 h incubation in NT and 0 - 24 h in CT. The addition of P produced higher demand under CT than NT. After incubation, biochemical indicators such as microbial respiration, glucose consumption, dehydrogenase activity and metabolic yield confirmed the higher glucose demands under NT and higher phosphorus demands under CT. These results demonstrate that C and P addition alter significantly the microbial response, suggesting that soil microorganisms present nutrient differential demands between CT and NT management systems.

    A simulation framework has been developed which defines a high-level architecture for a large-scale, comprehensive, scalable simulation of an Intelligent Transportation System (ITS). The simulator is designed to run on parallel computers and distributed (networked) computer systems; however, a version for a stand alone workstation is also available. The ITS simulator includes an Expert Driver Model (EDM) of instrumented ``smart`` vehicles with in-vehicle navigation units. The EDM is capable of performing optimal route planning and communicating with Traffic Management Centers (TMC). A dynamic road map data base is sued for optimum route planning, where the data is updated periodically to reflect any changes in road or weather conditions. The TMC has probe vehicle tracking capabilities (display position and attributes of instrumented vehicles), and can provide 2-way interaction with traffic to provide advisories and link times. Both the in-vehicle navigation module and the TMC feature detailed graphical user interfaces that includes human-factors studies to support safety and operational research. Realistic modeling of variations of the posted driving speed are based on human factor studies that take into consideration weather, road conditions, driver`s personality and behavior and vehicle type. The simulator has been developed on a distributed system of networked UNIX computers, but is designed to run on ANL`s IBM SP-X parallel computer system for large scale problems. A novel feature of the developed simulator is that vehicles will be represented by autonomous computer processes, each with a behavior model which performs independent route selection and reacts to external traffic events much like real vehicles. Vehicle processes interact with each other and with ITS components by exchanging messages. With this approach, one will be able to take advantage of emerging massively parallel processor (MPP) systems.

    1978-01-01

    As the thoughts of the country concentrate on the problems of transportation of waste through high traffic urban areas, the problem of how to deal directly and honestly with the public takes on greater significance in the nuclear industry. Non-technical aspects of the methods of transportation, especially by railroad and highway, enter into the total scheme of moving radioactive waste from both weapon and nuclear power plant sources to final processing and disposal. Factors such as shape, color, size, familiarity, and industrial designing are necessary ingredients that take on equal or more significance that the designing of containers to survive the hypothetical accident conditions of the present, or even of the future. Protective Packaging, Inc. has been a leader in the presentation of containers to the private and public sector of the nuclear industry. The products have undergone very open testing, in public, with both invited and uninvited witnesses. In those experiences, dating back to 1969, the problems of public acceptance will be related between the technical problems and the associated social and political problems that relate to container acceptance by the public in today's world. Proven experience data, relative to the safety of the present day systems will be discussed, as well as methods of improving the image in the future. Review will also be given to the effort by industry to discuss the proven record with parties outside the nuclear industry, i.e., individuals and pressure groups that are diametrically opposed to review the facts relative to safety as opposed to other, but more traditional industries

    The aim of this study was to analyze the survival of patients who initiated renal replacement therapy (RRT) with hemodialysis or peritoneal dialysis in the Brazilian Unified National Health System from 2002 to 2004. This was an observational, prospective, non-concurrent study. The study used the National Database for Renal Replacement Therapies resulting from probabilistic matching of Authorization of High-Complexity Procedures/Outpatient Information System and the Mortality Information System. The study included patients admitted in 2002 and 2003, with 3 months of treatment, and 18 years or older. Of the 31,298 patients, the majority: began RRT with hemodialysis, were male, with mean age 54 years, and living in the Southeast region and in municipalities with a mean HDI of 0.78. Increased risk of death was associated with: female gender, age greater than 55 years, diagnosis of diabetes mellitus, peritoneal dialysis, and not residing in the Southeast region. Residing in cities with higher HDI was associated with lower risk. Adjusted risk was HR = 1.17 in favor of hemodialysis. The results suggest shorter survival for peritoneal dialysis and older patients. It is thus necessary to support policies to better evaluate the RRT modality with studies that further elucidate the findings.

    Full Text Available The Brazilian Unified National Health System (Sistema Único de Saúde [SUS] is in a prominent position compared to the existing social policies. One of the new tools used by SUS is known as Performance Index of the Unified Health System (Índice de Desempenho do Sistema Único de Saúde [IDSUS], which is intended to measure the performance of each municipality. Therefore, the aim of this study was to propose a model of cost-effectiveness to compare IDSUS performance against total revenues achieved in Homogeneous Group 2, consisting of 94 municipalities and analysed using data from IDSUS and the System Information of the Public Budget for Health Care (Sistema de Informação do Orçamento Público em Saúde [SIOPS] for the year 2011. After structuring this data, we carried out descriptive statistical and cluster analysis in order to group similar municipalities in accordance with established variables: IDSUS performance, population and total revenue in health per capita. Even with the division of municipalities into homogeneous groups and after using variables such as population and revenue to regroup them, the results showed there are municipalities with heterogeneous characteristics. Another finding is in the use and intersection of two distinct databases (IDSUS and SIOPS, which allowed for visualizing the impact of health care revenue on the municipalities performance.

    Much of the work on Intelligent Transportation Systems (ITS) to date has emphasized technologies, standards/protocols, architecture, user services, core infrastructure requirements, and various other technical and institutional issues. ITS implementations in the United States and elsewhere in the world have demonstrated benefits in the areas of safety, productivity, efficiency, and environmental impact. However, quantitative benefits and satisfactory cost estimates are not available or cannot be derived for many components of the ITS, whether deployed individually or in some integrated fashion. The limitations of existing analysis and evaluation capabilities coupled with the lack of strong empirical evidence presents a major knowledge and data gap for infrastructure investment decisions involving ITS alternatives. This paper describes the over-arching issues and requirements associated with the analysis capabilities required for a systematic, faithful, and rigorous evaluation of the impacts of deploying ITS in a metropolitan area. It then describes the conceptual framework of a modeling system that will provide a preliminary analysis capability to support ITS deployment analysis and evaluation.

    The characteristics of electron internal transport barriers (eITBs) in helical systems are reviewed. The common features are highly peaked Te profile with strongly positive Er in the core region. The transition nature of Er based on neoclassical (NC) ambipolarity, with the clear threshold feature such as ECH power and Ohmic current, is the common mechanism for the eITB formation. The electron heat confinement improvement has been revealed within the eITB region. The ECH power threshold can be lowered in the presence of ripple-trapped electrons-induced convective flux, and rational surfaces at the core region. The gyrokinetic calculations, for example eITB in LHD, have shown that the ETG mode is unstable in eITB region due to the large Te gradient. A larger zonal flow amplitude has been observed in eITB phase in CHS. The geodesic transfer of energy from stationary zonal flow to oscillatory modes (GAMs) recognized in H-1 implies that the stationary zonal flows can be maintained at a higher level by reducing the geodesic curvature in helical systems. This is the first report of the eITB branch in the framework of the International Stellarator Profile DataBase (ISPDB). (Author)

The findings of the survey show that for a system to be characterize as libelous not just the separation of functions to accuse and judge. It is necessary to keep the separation for which the structure of dialectical process does not break, and the evidential initiative is always reserved for the parties.

    Silvopastoral management of fast-growing tree plantations is becoming popular in the Brazilian Cerrado (savanna). To understand the influence of such systems on soil carbon (C) storage, we studied C content in three aggregate size classes in six land-use systems (LUS) on Oxisols in Minas Gerais, Brazil. The systems were a native forest, a treeless pasture, 24- and 4-yr-old eucalyptus ( sp.) plantations, and 15- and 4-yr-old silvopastures of fodder grass plus animals under eucalyptus. From each system, replicated soil samples were collected from four depths (0-10, 10-20, 20-50, and 50-100 cm), fractionated into 2000- to 250-, 250- to 53-, and <53-μm size classes representing macroaggregates, microaggregates, and silt + clay, respectively, and their C contents determined. Macroaggregate was the predominant size fraction under all LUS, especially in the surface soil layers of tree-based systems. In general, C concentrations (g kg soil) in the different aggregate size fractions did not vary within the same depth. The soil organic carbon (SOC) stock (Mg C ha) to 1-m depth was highest under pasture compared with other LUS owing to its higher soil bulk density. The soils under all LUS had higher C stock compared with other reported values for managed tropical ecosystems: down to 1 m, total SOC stock values ranged from 461 Mg ha under pasture to 393 Mg ha under old eucalyptus. Considering the possibility for formation and retention of microaggregates within macroggregates in low management-intensive systems such as silvopasture, the macroaggregate dynamics in the soil seem to be a good indicator of its C storage potential.

    This study identifies the potential and limitations of contracting to improve health care management, accountability and quality, and expand the participation of teaching hospitals in the health service network in the context of the Restructuring Program of Teaching Hospitals in the Brazilian Unified Health System. It is a case study of four teaching hospitals and their contracting State Health Departments. According to the hospital managers, the association is weak between contracting and the presence of mechanisms for hospital insertion into the health service network with practices and structures for managerial and healthcare qualification in the hospital. More structured hospitals in managerial and healthcare terms were more structured between contracting and the State Health Department. There was an increase in production of medium complexity outpatient care and a decrease in primary healthcare procedures. The proposal is for ongoing managerial development of the hospital and of the State Health Department, review of the operational plan, budgeting, monitoring mechanisms and an incentive system, bonding in the teams, among others.

    2009-12-19

    The recent discovery of new deep water and ultra-deep water oil and gas fields offshore Brazil, including pre-salt reservoirs, has become a focal point for field development Operators and Contractors. The aggressive nature of fluids (sour, high density) in combination with deeper waters implies potential flow assurance issues. These issues challenge riser and pipeline technology to find cost effective solutions for hydrocarbon fluid transfer in field development scenarios involving phased tied-back. The near-surface GAP{sup TM}, system (Gravity Actuated Pipe{sup TM}), which has been in operation for more than two years on the Kikeh field offshore Malaysia in 1325 m of water between a Dry Tree Unit (SPAR) and a turret-moored FPSO, is considered to meet these challenges since such a product is quasi independent of water depth and takes advantage of being near surface to optimize flow assurance. Furthermore the GAP{sup TM} has undergone technical upgrades when compared to the Kikeh project in order to make it suitable for the more hostile met ocean conditions offshore Brazil. This paper presents the design features, the construction and assembly plans in Brazil and the offshore installation of a GAP fluid transfer system for operation in Brazilian deep waters. (author)

    Full Text Available ABSTRACT Objective: to analyze the profile of appendectomies performed in the Brazilian Public Health System (SUS and to compare the laparoscopic and laparotomic techniques of appendectomy. Methods: This work used information from DataSus from 2008 to 2014 (http://datasus.saude.gov.br. We compared the data of patients submitted to laparotomic appendectomy with those submitted to laparoscopic one. Results: when comparing the total growth of appendectomies, the laparoscopic route increased 279.7%, while the increase in laparotomic surgery was 25% (p <0.001 in the study period. With regard to medical and hospital costs, laparoscopic appendectomy accounted for only 2.6% of the total expenditure on appendectomies performed by the Unified Health System (SUS hospitals, with an average cost 7.6% lower than that of laparotomy procedures, but without statistical significance. The mortality rate was 57.1% lower in the laparoscopic approach when compared with laparotomy. Conclusion: there has been a significant increase in the laparoscopic route in the treatment of appendicitis, but the method is still rarely used in SUS patients. The costs of laparoscopic appendectomy were similar to those observed in laparotomic access.

    Full Text Available ABSTRACT Human insulin is provided by the Brazilian Public Health System (BPHS for the treatment of diabetes, however, legal proceedings to acquire insulin analogs have burdened the BPHS health system. The aim of this study was to perform a cost-effectiveness analysis to compare insulin analogs and human insulins. This is a pharmacoeconomic study of cost-effectiveness. The direct medical cost related to insulin extracted from the Ministry of Health drug price list was considered. The clinical results, i.e. reduction in glycated hemoglobin (HbA1c, were extracted by meta-analysis. Different scenarios were structured to measure the uncertainties regarding the costs and reduction in HbA1c. Decision tree was developed for sensitivity of Incremental Cost Effectiveness Ratio (ICER. A total of fifteen scenarios were structured. Given the best-case scenario for the insulin analogs, the insulins aspart, lispro, glargine and detemir showed an ICER of R$ 1,768.59; R$ 3,308.54; R$ 11,718.75 and R$ 2,685.22, respectively. In all scenarios in which the minimum effectiveness was proposed, lispro, glargine and detemir were dominant strategies. Sensitivity analysis showed that the aspart had R$ 3,066.98 [95 % CI: 2339.22; 4418.53] and detemir had R$ 6,163.97 [95% CI: 3919.29; 11401.57] for incremental costs. We concluded there was evidence that the insulin aspart is the most cost-effective.

    Full Text Available Context: Oils and butter of seed from Brazilian biodiversity are extending the range of innovative products for cosmetics development. They have a fat potential similar to skin composition, leading to the improved performance of these product. Aims: Improve the emulsions spreadability through prior screening of grease composition and studying the viscosity, and the emulsions accelerated stability. Methods: Emulsions were formulated using oils from semiarid plants from Bahia: Syagrus coronate, Pachira retusa, and Pachira aquatica, so as to compare them with oils already standard in the production of cosmetics. Spreadability and stability tests were made comparing the results. The same criteria were used with Amazon seed butter: Virola surinamensis, Butyrospermum parkii, Astrocaryum murumuru, Theobroma cacao and Theobroma grandiflorum. For the emulsions screening and performance, a system was developed for oil/ butter, following tests of accelerated stability, viscosity, and spreadability. Results: The combined system of spreadability was optimized using screening. Emollients containing oleic and palmitic acids, and light chain fatty acids obtained good spreadability. The oil emulsion containing Pachira retusa and Virola surinamensis butter had a higher viscosity. Conclusions: With high content of fatty acids such as oleic, palmitic or the light chain fatty acids obtain an appropriated appearance, texture, and spreadability for cosmetic use. Thus, oils with a low fatty acid content may be combined with butter that have a high fatty acid content and vice-versa. Analyzing and strategically combining grease composition, one can optimize the performance of cosmetic formulations.

    To discuss factors related to the financing of the Basic Component of Pharmaceutical Services within the municipal management of the Brazilian Unified Health System. The Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil - Serviços (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services) is a cross-sectional, exploratory, and evaluative study that performed an information survey in a representative sample, stratified by Brazilian regions It considered different study populations in the sampling plan, which represent primary health care services in the cities. Data were collected in 2015 by two methods: in person, by applying direct observation scripts and interviews with users, physicians, and professionals responsible for the dispensing of medicines in primary care services; by telephone interviews with municipal health managers and municipal professionals responsible for Pharmaceutical Services. The results were extracted from the questionnaires applied by telephone. Of the sample of 600 eligible cities, we collected 369 interviews (61.5%) with secretaries and 507 (84.5%) with pharmaceutical services managers. 70.8% of the cities have a computerized management system; and 11.9% have qualification/training of professionals. More than half (51.3%) of the cities received funds for the structuring of pharmaceutical services, and almost 60% of these cities performed this type of spending. In 35.4% of cases, municipal secretaries of health said that they use resources of medicines from the Componente Básico da Assistência Farmacêutica (CBAF - Basic Component of Pharmaceutical Services) to cover demands of other medicines, but only 9.7% believed that these funds were sufficient to cover the demands. The existence of a permanent bidding committee exclusively for acquiring medicines was reported in 40.0% of the cities. We found serious deficiencies in the public financing of

    Full Text Available ABSTRACT OBJECTIVE To examine whether the level of complexity of the services structure and sociodemographic and clinical characteristics of patients in hemodialysis are associated with the prevalence of poor health self-assessment. METHODS In this cross-sectional study, we evaluated 1,621 patients with chronic terminal kidney disease on hemodialysis accompanied in 81 dialysis services in the Brazilian Unified Health System in 2007. Sampling was performed by conglomerate in two stages and a structured questionnaire was applied to participants. Multilevel multiple logistic regression was used for data analysis. RESULTS The prevalence of poor health self-assessment was of 54.5%, and in multivariable analysis it was associated with the following variables: increasing age (OR = 1.02; 95%CI 1.01–1.02, separated or divorced marital status (OR = 0.62; 95%CI 0.34–0.88, having 12 years or more of study (OR = 0.51; 95%CI 0.37–0.71, spending more than 60 minutes in commuting between home and the dialysis service (OR = 1.80; 95%CI 1.29–2.51, having three or more self-referred diseases (OR = 2.20; 95%CI 1.33–3.62, and reporting some (OR = 2.17; 95%CI 1.66–2.84 or a lot of (OR = 2.74; 95%CI 2.04–3.68 trouble falling asleep. Individuals in treatment in dialysis services with the highest level of complexity in the structure presented less chance of performing a self-assessment of their health as bad (OR = 0.59; 95%CI 0.42–0.84. CONCLUSIONS We showed poor health self-assessment is associated with age, years of formal education, marital status, home commuting time to the dialysis service, number of self-referred diseases, report of trouble sleeping, and also with the level of complexity of the structure of health services. Acknowledging these factors can contribute to the development of strategies to improve the health of patients in hemodialysis in the Brazilian Unified Health System.

    Full Text Available In the Brazilian Cerrado (neotropical savanna, the development of bud-bearing underground systems as adaptive structures to fire and dry periods can comprise an important source of buds for this ecosystem, as already demonstrated in the Brazilian Campos grasslands and North American prairies. Asteraceae species from both woody and herbaceous strata have subterranean organs that accumulate carbohydrates, reinforcing the adaptive strategy of these plants to different environmental conditions. This study aims to analyse the morpho-anatomy of underground systems of six species of Asteraceae (Mikania cordifolia L.f. Willd., Mikania sessilifolia DC, Trixis nobilis (Vell. Katinas, Pterocaulon alopecuroides (Lam. DC., Vernonia elegans Gardner and Vernonia megapotamica Spreng., to describe these structures and to verify the occurrence and origin of shoot buds, and to analyse the presence of reserve substances. Individuals sampled in Cerrado areas in São Paulo State showed thick underground bud-bearing organs, with adventitious or lateral roots and presence of fructans. Xylopodium was found in all studied species, except for Trixis nobilis, which had stem tuber. The presence of fructans as reserve, and the capacity of structures in the formation of buds indicate the potential of herbaceous species of Asteraceae in forming a viable bud bank for vegetation regeneration in the Brazilian Cerrado.No Cerrado brasileiro (savana neotropical, o desenvolvimento de sistemas subterrâneos que produzem gemas, como estruturas adaptativas contra o fogo e períodos de seca, pode compreender um importante suprimento de gemas para esse ecossistema, como já demonstrado nos campos brasileiros e nas pradarias norte-americanas. Espécies de Asteraceae tanto do estrato lenhoso, quanto do herbáceo têm órgãos que acumulam carboidratos, reforçando a estratégia adaptativa dessas plantas a diferentes condições ambientais.

    The aim of this dissertation is to define a consistent set of indicators for the environmental assessment of different energy transport systems: high-voltage alternating and direct current transmission lines, electric cables, pipelines for gas and oil, inland waterway, road and rail transportation, according to state-of-the-art technologies. The indicator system is used for comparative analysis and identification of environmental hot-spots of the different systems. The environmental performance of power plants close to production or unloading terminals with subsequent power transmission and the transport of fossil fuels with power production close to the end-users is compared. Quantitative indicators are defined for different impact categories: fossil energy depletion, impacts from emissions, land use, noise impacts and visibility. A further aggregation of the different indicators to obtain a universal environmental score was not envisaged. It was not possible to define a quantitative indicator for possible electric and magnetic field effects because of insufficient knowledge of the involved dose-response metrics. The proposed indicators quantify dose-response relationships also below emission or immission limits imposed by law, which was one of the main requirements in this work. By reducing all information to an equivalent impacted area, a high level of consistency was achieved for land use, noise impacts and visibility indicators. Other indicators refer to the energy content of fossil resources and to equivalent emissions of reference substances. The calculation of an equivalent impacted area was not considered an efficient approach in these cases. The performance of the proposed indicator system and its applicability to infrastructure and regional planning is tested in two practical examples. (author) figs., tabs., refs

    2010-01-01

    This paper shows that a well designed transport system has an embedded exchange value by serving as a market for potential exchange between consumers. Under suitable conditions, one can improve the welfare of consumers in the system simply by allowing some exchange of goods between consumers during transportation without incurring additional transportation cost. We propose an explicit valuation formula to measure this exchange value for a given compatible transport system. This value is always nonnegative and bounded from above. Criteria based on transport structures, preferences and prices are provided to determine the existence of a positive exchange value. Finally, we study a new optimal transport problem with an objective taking into account of both transportation cost and exchange value.

    Full Text Available Intelligent Transport Services expect availability of the secure seamless communications solutions typically covering widely spread areas. Different ITS solutions require different portfolio of telecommunications service quality. These parameters have to correspond with ITS service performance parameters required by specific service. Even though quite extensive range of public wireless data services with reasonable coverage are provided, most of them are provided with no guaranteed quality and security. ITS requirements can be in most parameters easier reached if multi-path communications systems are applied core solution is combined with both public as well as private ones where and when it is needed. Such solution requires implementation of relevant flexible system architecture supported by the efficient decision processes. This paper is concentrated the telecommunications security issues relevant to the ITS wide area networking. Expected level of security varies in dependence on relevant ITS service requirements. Data volumes transferred both in private data vehicle on board networks as well as between vehicles and infrastructure (C2I or other vehicles (C2C progressively grow. Such trend upsurges the fatal problems appearance probability in case security of the wide area networks is not relevantly treated. That is reason why relevant communications security treatment becomes crucial part of the ITS solution. Besides of available "off shelf" security tools we present solution based on non-public universal identifier with dynamical extension (time and position dependency as an autonomous variables and data selection according to actor role or category. Presented results were obtained within projects e-Ident1, DOTEK2 and SRATVU3.

    Transport is one of the most challenge sectors when addressing energy security and climate change due to its high reliance on oil products and lack of the alternative fuels. This paper explores the ability of three transport strategies to contribute to the development of a sustainable transport in China. With this purpose in mind, a Chinese transport model has been created and three current transport strategies which are high speed railway (HSR), urban rail transit (URT) and electric vehicle (EV) were evaluated together with a reference transport system in 2020. As conservative results, 13% of the energy saving and 12% of the CO 2 emission reduction can be attained by accomplishing three strategies compared with the reference transport system. However, the energy demand of transport in 2020 with the implementation of three strategies will be about 1.7 times as much as today. The three strategies show the potential of drawing the transport demand to the more energy efficient vehicles; however, more initiatives are needed if the sustainable transport is the long term objective, such as the solutions to stabilise the private vehicle demands, to continuously improve the vehicle efficiency and to boost the alternative fuels produced from the renewable energy sources. - Highlights: • A Chinese transport model was created and three transport strategies were evaluated • Transport is the biggest driver of the oil demand in China not the industry • The energy demand of transport in 2020 will be twice as much as today • Strategies contribute 13% energy saving and 12% CO 2 emission reduction • More initiatives are needed if a sustainable transport is the long-term objective

To analyze the availability of medicines, we verified 50 items selected from the Relação Nacional de Medicamentos Essenciais (Rename - National List of Essential Medicines) of 2012. Observation scripts were applied to medicine dispensing services in the primary health care. Interviews were carried out with patients, health care professionals, and public managers, using semi-structured questionnaires. The availability index was presented as the percentage of health units where the medicines were available. For statistical analysis, absolute, relative, and mean frequencies were presented (with 95% confidence intervals). The comparison of groups was carried out by Pearson Chi-square tests or variance analysis, when needed. One thousand, one hundred, and seventy-five observation scripts were filled in a national representative sample composed by 273 cities. Statistically significant differences were observed regarding the type of unit, infrastructure, and presence of a pharmacist between regions of Brazil. The average availability of tracer medicines in primary health care was 52.9%, with differences between regions and sampling strata. This index increased to 62.5% when phytotherapic medicines were excluded. We found limited availability of medicines for treatment of chronic and epidemiological diseases, such as tuberculosis and congenital syphilis.

    Full Text Available Abstract Background: Heart surgery has developed with increasing patient complexity. Objective: To assess the use of resources and real costs stratified by risk factors of patients submitted to surgical cardiac procedures and to compare them with the values reimbursed by the Brazilian Unified Health System (SUS. Method: All cardiac surgery procedures performed between January and July 2013 in a tertiary referral center were analyzed. Demographic and clinical data allowed the calculation of the value reimbursed by the Brazilian SUS. Patients were stratified as low, intermediate and high-risk categories according to the EuroSCORE. Clinical outcomes, use of resources and costs (real costs versus SUS were compared between established risk groups. Results: Postoperative mortality rates of low, intermediate and high-risk EuroSCORE risk strata showed a significant linear positive correlation (EuroSCORE: 3.8%, 10%, and 25%; p < 0.0001, as well as occurrence of any postoperative complication EuroSCORE: 13.7%, 20.7%, and 30.8%, respectively; p = 0.006. Accordingly, length-of-stay increased from 20.9 days to 24.8 and 29.2 days (p < 0.001. The real cost was parallel to increased resource use according to EuroSCORE risk strata (R$ 27.116,00 ± R$ 13.928,00 versus R$ 34.854,00 ± R$ 27.814,00 versus R$ 43.234,00 ± R$ 26.009,00, respectively; p < 0.001. SUS reimbursement also increased (R$ 14.306,00 ± R$ 4.571,00 versus R$ 16.217,00 ± R$ 7.298,00 versus R$ 19.548,00 ± R$935,00; p < 0.001. However, as the EuroSCORE increased, there was significant difference (p < 0.0001 between the real cost increasing slope and the SUS reimbursement elevation per EuroSCORE risk strata. Conclusion: Higher EuroSCORE was related to higher postoperative mortality, complications, length of stay, and costs. Although SUS reimbursement increased according to risk, it was not proportional to real costs.

    Full Text Available Corruption is one of the serious Brazilian problems. The embezzlement of public funds prevents the realization of fundamental social rights and delays national develop- ment prevent inhibiting the real access to citizenship. Brazil needs to face the paradox of being the eighth world’s largest economy, and having low human development indexes. Social justice does not coexist with impunity. Public funds, paid by taxpayers, sidetracked by corruption schemes, fail to reach the investments in the enlargement of public health, education, security and infrastructure. Moreover, the opportunity of corruption increases corruption when there is impunity. To reduce corruption levels in Brazil, it is urgent to think about legal system improvement alternatives, a task which is also entrusted to the academy. Although positive law does not change social reality, the lack of appropriate legal mechanisms prevents the equating of part of the Brazilian’s society problems, such as corruption. In the extrapenal sphere, beginning with constitutional law, it is important to emphasize the need to improve issues such as the strengthening of internal and external controls, reforming constitutional institutions, such as the Courts of Auditors. In addi- tion, the enlargement of transparency and social control of the prosecution performance in infra constitutional sphere requires fundamental legislative reforms, in order to provide for the realization of the human rights enshrined in the 1988 Constitution.

  11. Dermatophilosis in sheep raised under rotational grazing systems on irrigated pastures in the Brazilian semiarid region

    Vanessa Diniz Vieira

    Full Text Available ABSTRACT: Seventeen outbreaks of dermatophilosis are reported from three farms affecting Santa Inês and Santa Inês x Dorper sheep that were reared in irrigated areas with rotational grazing at a stocking rate of 50 to 100 sheep per hectare, in the Brazilian semiarid region. Most outbreaks occurred after rains and affected sheep of different ages, with morbidity rates of 0.77% to 31%. Clinical signs were dermatitis with crusts that stood out easily and left areas of alopecia. Dermatophilus congolensis was isolated in cultures in 5% sheep blood agar by means of Haalstra’s method. Histologically, the epidermis showed extensive multifocal areas of ortho and parakeratotic hyperkeratosis with intracorneal microabscesses and presence of D. congolensis. Sheep affected were isolated from the flocks and they recovered after treatment with 70,000IU of procaine penicillin G and 70mg of dihydrostreptomycin sulphate per kg of bodyweight. Dermatophilosis is a frequent endemic disease in rotational grazing systems with irrigated pastures and high stocking rates, which occurs with higher frequency after rains and can be controlled efficiently through isolation of the affected sheep, followed by application of a single dose of penicillin and streptomycin.

    Return to work is an objective parameter used worldwide to evaluate the success of organ transplantation and is especially feasible after renal transplantation. This study sought to describe the frequency of return to work after renal transplantation and related characteristics. Retrospective cohort of 511 isolated kidney transplant recipients was recruited from a Brazilian referral center from January 2005 to December 2009; all were matched to the public social security database to determine inclusion and benefit awards, as well as the rate of resumption of contributions to the public social security system, a surrogate marker of work rehabilitation. Characteristics associated with work return were analyzed. No social security records were found for 28 subjects. The remaining 483 subjects had a mean age of 45±13 years; 62% were male; 401 (83%) received some public social security benefit; 298 were paying dues and could, therefore, receive temporary or permanent disability benefits. Of these, 78 subjects made social security payments after transplantation, resulting in a work return rate of 26% (95% confidence interval, 21-32). Younger age, living donor graft, and chronic glomerulonephritis were significantly associated with return to work. In Brazil, most renal transplant recipients are on social security benefits, but only a small proportion return to work after surgery. Clinical characteristics may help define work resumption trends.

    The palette of some of the most representative Brazilian painters from the XIX century was characterized using EDXRF technique. In this work were analyzed paintings of: Eliseu Visconti, Almeida Junior, Rodolfo Amoedo, Henrique Bernardelli, Rafael Frederico, Modesto Brocos, Augusto Rodrigues Duarte and Pedro Peres - all of them belonging to the National Museum of Fine Arts Collection. EDXRF measurements were carried out with a portable system developed by the Nuclear Instrumentation Laboratory, consisting of an X-ray tube Oxford TF3005 with tungsten (W) anode, operating at 25 kV and 100 μA, and a Si-PIN XR-100CR detector from Amptek. In each color and distinct hue of the paint layer were obtained several spectra, with an acquisition time of 300 s and a beam collimation of 2 mm. The spectra were processed and analyzed using the software QXAS-AXIL from IAEA. Some pigments used by the artists were: zinc white, lead white, ochre, umbra, vermilion, Prussian blue, cobalt blue, cadmium yellow, black iron oxide, manganese violet, etc. These results - together with the Computed Radiography analyses - have been used to create a database about the XIX century collection of the National Museum of Fine Arts, in order to assist restorators, conservators, art students and researchers in the field of archaeometry

    The approval of the National Policy of Integrative and Complementary Practices fosters the provision of Community Therapy in the Brazilian Unified Health System (SUS). This initiative seeks to develop the necessary competencies to attend to the psychosocial demands in the professionals and the community leadership and to build support networks in order to extend the efficacy of Primary Health Care. This study aims to describe the social representation on the community therapist prepared by health care professionals employed at SUS. Semi-structured interviews were conducted with 27 professionals who were trained in Community Therapy in 2009 by the State Health Department of Santa Catarina in partnership with the Ministry of Health. Data analysis was carried out by descending hierarchical classification. The results revealed that there is a social representation among the professionals regarding what it signifies to be a community therapist, seen as someone who humanizes interpersonal relations in the health care sector. However, Primary Health Care professionals still subscribe to a less horizontalized group practice model than professionals working at the secondary level of care, represented in this study by the Psychosocial Care Centers (CAPS).

    The purpose of the Advanced Transportation System Study (ATSS) task area 1 study effort is to examine manned launch vehicle booster concepts and two-way cargo transfer and return vehicle concepts to determine which of the many proposed concepts best meets NASA's needs for two-way transportation to low earth orbit. The study identified specific configurations of the normally unmanned, expendable launch vehicles (such as the National Launch System family) necessary to fly manned payloads. These launch vehicle configurations were then analyzed to determine the integrated booster/spacecraft performance, operations, reliability, and cost characteristics for the payload delivery and return mission. Design impacts to the expendable launch vehicles which would be required to perform the manned payload delivery mission were also identified. These impacts included the implications of applying NASA's man-rating requirements, as well as any mission or payload unique impacts. The booster concepts evaluated included the National Launch System (NLS) family of expendable vehicles and several variations of the NLS reference configurations to deliver larger manned payload concepts (such as the crew logistics vehicle (CLV) proposed by NASA JSC). Advanced, clean sheet concepts such as an F-1A engine derived liquid rocket booster (LRB), the single stage to orbit rocket, and a NASP-derived aerospace plane were also included in the study effort. Existing expendable launch vehicles such as the Titan 4, Ariane 5, Energia, and Proton were also examined. Although several manned payload concepts were considered in the analyses, the reference manned payload was the NASA Langley Research Center's HL-20 version of the personnel launch system (PLS). A scaled up version of the PLS for combined crew/cargo delivery capability, the HL-42 configuration, was also included in the analyses of cargo transfer and return vehicle (CTRV) booster concepts. In addition to strictly manned payloads, two-way cargo

    Full Text Available We aimed to evaluate the technical efficiency and economic viability of the implementation and use of four cattle identification methods allowed by the Brazilian traceability system. The study was conducted in a beef cattle production system located in the State of Mato Grosso, from January to June 2012. Four identification methods (treatments were compared: T1: ear tag in one ear and ear button in the other ear (eabu; T2: ear tag and iron brand on the right leg (eaib; T3: ear tag in one ear and tattoo on the other ear (eata; and T4: ear tag in one ear and electronic ear tag (eael on the other. Each treatment was applied to 60 Nelore animals, totaling 240 animals, divided equally into three life stages (calves, young cattle, adult cattle. The study had two phases: implementation (phase 1 and reading and transfer of identification numbers to an electronic database (phase 2. All operating expenses related to the two phases of the study were determined. The database was constructed, and the statistical analyses were performed using SPSS® 17.0 software. Regarding the time spent on implementation (phase 1, conventional ear tags and electronic ear tags produced similar results, which were lower than those of hot iron and tattoo methods, which differed from each other. Regarding the time required for reading the numbers on animals and their transcription into a database (phase 2, electronic ear-tagging was the fastest method, followed by conventional ear tag, hot iron and tattoo. Among the methods analyzed, the electronic ear tag had the highest technical efficiency because it required less time to implement identifiers and to complete the process of reading and transcription to an electronic database and because it did not exhibit any errors. However, the cost of using the electronic ear-tagging method was higher primarily due to the cost of the device.

    To characterize the polypharmacy in primary health care patients and to identify its associated factors. This is a cross-sectional, exploratory, and evaluative study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). The variable of interest was polypharmacy, defined as the use of five or more medicines. We sought to identify the association of sociodemographic variables and indicators of health conditions to polypharmacy. For group comparison, the Pearson's Chi-square test was used. The association between polypharmacy and explanatory variables was evaluated by logistic regression model (p < 0.05). The quality of the adjustment was verified by Hosmer-Lemeshow test. The prevalence of polypharmacy among medicine users was 9.4% (95%CI 7.8-12.0) in the general population and 18.1% (95%CI 13.6-22.8) in older adults above 65 years old. We found statistically significant association between polypharmacy and age above 45 years, lower self-perception of health, presence of chronic diseases, having health insurance, care in emergency services, and region of the Country. South users presented the highest chances to polypharmacy. The most used medicines were those of the cardiovascular system, being compatible with the national epidemiological profile. Polypharmacy is a reality in the population met within the primary care of Brazilian Unified Health System and may be related to excessive or inappropriate use of medicines. The main challenge to qualify health care is to ensure that prescription of multiple medicines be appropriate and safe.

    Ethanol has been recently of great interest due to two main reasons. First, it is a viable alternative to oil derivates used in light vehicles, which price has been substantially raised in the last years. In second place because ethanol is a renewable source of energy, that mitigates the emission of greenhouse effect gases. Although Brazil is losing its leadership of ethanol production for the United States, it raises internationally as the leading country to develop its ethanol production from biomass. Differently from the American system which relies on corn as principal raw material, Brazilian ethanol is produced from sugarcane. The Brazilian route shows up as much more competitive and much less pollution contributor than the American one. The objective of this work is to analyze the leading aspects of the Brazilian Innovation System built around the sugarcane industry. The Brazilian success in terms of sugarcane can not be understood just as based in a natural comparative advantage, but it is a result of accumulation of efforts which ended in a virtuous trajectory of technological learning, relying, mostly, in incremental innovations. That process had, as inflection point, the Pro Alcohol Program, launched after the first oil crisis in 1973. From that Program on, the agricultural industry started the diffusion of innovations making possible constant increases of productivity and cost reduction on its production. The technological advance brought benefit to the alcohol and sugar production, of which Brazil became the main world producer. This work is based on the approach of national systems of innovation, according to which the innovative performance of a country, region or even a sector, can not be learned only by focusing the efforts and performance of the companies. Innovation results from the interaction of actors from different institutional nature. To analyze the institutional arrangements as the basis to the innovative process, this work will get

Solute carrier (SLC superfamily is composed of a series of transporters that are ubiquitously expressed in organs and tissues of digestive systems and mediate specific uptake of small molecule substrates in facilitative manner. Given the important role of SLC proteins in maintaining normal functions of digestive system, dysregulation of these protein in digestive system neoplasms may deliver biological and clinical significance that deserves systemic studies. In this review, we critically summarized the recent advances in understanding the role of SLC proteins in digestive system neoplasms. We highlighted that several SLC subfamilies, including metal ion transporters, transporters of glucose and other sugars, transporters of urea, neurotransmitters and biogenic amines, ammonium and choline, inorganic cation/anion transporters, transporters of nucleotide, amino acid and oligopeptide organic anion transporters, transporters of vitamins and cofactors and mitochondrial carrier, may play important roles in mediating the initiation, progression, metastasis, and chemoresistance of digestive system neoplasms. Proteins in these SLC subfamilies may also have diagnostic and prognostic values to particular cancer types. Differential expression of SLC proteins in tumors of digestive system was analyzed by extracting data from human cancer database, which revealed that the roles of SLC proteins may either be dependent on the substrates they transport or be tissue specific. In addition, small molecule modulators that pharmacologically regulate the functions of SLC proteins were discussed for their possible

    When a transportation accident occurs, all entities including the shipper, the transportation organization, local governments, and emergency response organizations must have organized and planned for civil safety, property, and environmental protection. When a transportation accident occurs, many related organizations will be involved, and their cooperation determines the success or failure of the response. The point where the accident happens cannot be pinpointed in advance. Nuclear fuel transportation also requires a quick response from a viewpoint of security. A tracking system for radioactive material transport is being developed for use in Japan. The objective of this system is, in the rare event of an accident, for communication capabilities to share specific information among relevant organizations, the transporter, and so on

    At the US Department of Energy (DOE) 80 transportation facilities, each contractor's transportation management operation has different internal and site specific procedures, and reports to a DOE regional Field Office Traffic Manager (FOTM). The DOE Transportation Management Program (TMP) has the responsibility to manage a transportation program for safe, efficient, and economical transportation of DOE-owned materials. The TMP develops and administers transportation/traffic operations management policies and programs for materials; including radioactive materials, other hazardous materials, hazardous substances, and hazardous wastes, pursuant to applicable federal regulations, such as the Code of Federal Register, Sections 40 and 49. Transportation management has become an increasingly critical primarily because of transportation issues regarding the shipment of radioactive materials and hazardous wastes that are frequently the focus of public concerns. A large shipments and requiring millions of business transactions necessitates the establishment of automated systems, programs, procedures, and controls to ensure that the transportation management process in being handled in a safe, efficient, and economical manner. As the mission of many DOE facilities changes from production of special nuclear materials for defense purposes to environmental restoration and waste management, the role of transportation management will become even more important to the safe and efficient movement of waste materials to prescribed locations. In support of this role, the Automated Transportation Management System (ATMS) was conceived to assist the DOE and its contractors in the performance of their day-to-day transportation management activities. The ATMS utilizes the latest in technology and will supply state-of-the-art automated transportation management for current and future DOE transportation requirements

  12. Ship Routing with Pickup and Delivery for a Maritime Oil Transportation System: MIP Model and Heuristics

    Directory of Open Access Journals (Sweden)

    Vinícius P. Rodrigues

    2016-09-01

    Full Text Available This paper examines a ship routing problem with pickup and delivery and time windows for maritime oil transportation, motivated by the production and logistics activities of an oil company operating in the Brazilian coast. The transportation costs from offshore platforms to coastal terminals are an important issue in the search for operational excellence in the oil industry, involving operations that demand agile and effective decision support systems. This paper presents an optimization approach to address this problem, based on a mixed integer programming (MIP model and a novel and exploratory application of two tailor-made MIP heuristics, based on relax-and-fix and time decomposition procedures. The model minimizes fuel costs of a heterogeneous fleet of oil tankers and costs related to freighting contracts. The model also considers company-specific constraints for offshore oil transportation. Computational experiments based on the mathematical models and the related MIP heuristics are presented for a set of real data provided by the company, which confirm the potential of optimization-based methods to find good solutions for problems of moderate sizes.

    Purpose: To effectively avoid an obstacle in a fuel transporting device by reading the outputs of absolute position detectors mounted on movable trucks, controlling the movements of the trucks, and thereby smoothly and accurately positioning the fuel transporting device at predetermined position and providing a contact detector thereat. Method: The outputs from absolute position detectors which are mounted on a longitudinally movable truck and a laterally movable truck are input to an input/output control circuit. The input/output control circuit serves to compare, the position a fuel transporting device is to be moved to, with the present position on the basis of said input detection signal and a command signal from an operator console, to calculate the amount of movement to be driven, to produce an operation signal therefor to a control panel, and to drive and control the drive motors which are respectively mounted on the trucks for the fuel transfer device. On the other hand, in case that the transfer device comes into contact with an obstacle, the contact detector will immediately operate to produce a stop command through the control panel to the transporting device, and avoid a collision with the obstacle.

    Digestive system neoplasms are the leading causes of cancer-related death all over the world. Solute carrier (SLC) superfamily is composed of a series of transporters that are ubiquitously expressed in organs and tissues of digestive systems and mediate specific uptake of small molecule substrates in facilitative manner. Given the important role of SLC proteins in maintaining normal functions of digestive system, dysregulation of these protein in digestive system neoplasms may deliver biological and clinical significance that deserves systemic studies. In this review, we critically summarized the recent advances in understanding the role of SLC proteins in digestive system neoplasms. We highlighted that several SLC subfamilies, including metal ion transporters, transporters of glucose and other sugars, transporters of urea, neurotransmitters and biogenic amines, ammonium and choline, inorganic cation/anion transporters, transporters of nucleotide, amino acid and oligopeptide organic anion transporters, transporters of vitamins and cofactors and mitochondrial carrier, may play important roles in mediating the initiation, progression, metastasis, and chemoresistance of digestive system neoplasms. Proteins in these SLC subfamilies may also have diagnostic and prognostic values to particular cancer types. Differential expression of SLC proteins in tumors of digestive system was analyzed by extracting data from human cancer database, which revealed that the roles of SLC proteins may either be dependent on the substrates they transport or be tissue specific. In addition, small molecule modulators that pharmacologically regulate the functions of SLC proteins were discussed for their possible application in the treatment of digestive system neoplasms. This review highlighted the potential of SLC family proteins as drug target for the treatment of digestive system neoplasms.

    Increasing focus on sustainability affects all parts of the energy system. Integrating the power and transport system in future energy system planning, influences the economically optimal investments and optimal operation of the power system as well as the transport system. This work presents...... analysis of the optimal configuration and operation of the integrated power and transport system in Northern Europe. Optimal configuration and operation is obtained using the optimisation model, Balmorel [1], with a transport model extension. For electric drive vehicles with plug-in capabilities...... it is assumed that power can go both from grid-to-vehicle and vehicle-to-grid. Oil prices are assumed to be $120/barrel, and CO2 price 40 €/ton. This results in an optimal investment path with a large increase in sustainable energy; primarily wind energy, as well as an increase in the electric drive vehicles...

    CERN Document Server

    Horsthemke, Werner; Mendez, Vicenc

    2010-01-01

    This book is an introduction to the dynamics of reaction-diffusion systems, with a focus on fronts and stationary spatial patterns. Emphasis is on systems that are non-standard in the sense that either the transport is not simply classical diffusion (Brownian motion) or the system is not homogeneous. A important feature is the derivation of the basic phenomenological equations from the mesoscopic system properties. Topics addressed include transport with inertia, described by persistent random walks and hyperbolic reaction-transport equations and transport by anomalous diffusion, in particular subdiffusion, where the mean square displacement grows sublinearly with time. In particular reaction-diffusion systems are studied where the medium is in turn either spatially inhomogeneous, compositionally heterogeneous or spatially discrete. Applications span a vast range of interdisciplinary fields and the systems considered can be as different as human or animal groups migrating under external influences, population...

    This thesis highlights the nuclear energy perspectives to regain a prominent place in the world energy mix, as a competitive and safe energy source. Just considering the current international changes in the nuclear power features in the developed countries, it is assessed the suitability and feasibility of defining a new nuclear policy in Brazil, based on the development of small and medium nuclear power reactors - SMNPR. The SMNPR's may be a good nuclear strategy for Brazil to develop a national and evolutionary reactor design with several improvements in safety, by means of passive safety systems. This reactor may play a significant role in the brazilian electrical system in the long term. (author)

    2013-07-01

    This study aimed to investigate the performance of the Hospital Information System of the Brazilian Unified National Health System (SIH-SUS) in identifying cases of maternal near miss in a hospital in Rio de Janeiro, Brazil, in 2008. Cases were identified by reviewing medical records of pregnant and postpartum women admitted to the hospital. The search for potential near miss events in the SIH-SUS database relied on a list of procedures and codes from the International Classification of Diseases, 10th revision (ICD-10) that were consistent with this diagnosis. The patient chart review identified 27 cases, while 70 potential occurrences of near miss were detected in the SIH-SUS database. However, only 5 of 70 were "true cases" of near miss according to the chart review, which corresponds to a sensitivity of 18.5% (95%CI: 6.3-38.1), specificity of 94.3% (95%CI: 92.8-95.6), area under the ROC of 0.56 (95%CI: 0.48-0.63), and positive predictive value of 10.1% (IC95%: 4.7-20.3). These findings suggest that SIH-SUS does not appear appropriate for monitoring maternal near miss.

  1. Human behavior research and the design of sustainable transport systems

    Schauer, James J.

    2011-09-01

    Transport currently represents approximately 19% of the global energy demand and accounts for about 23% of the global carbon dioxide emissions (IEA 2009). As the demand for mobility is expected to continue to increase in the coming decades, the stabilization of atmospheric carbon dioxide levels will require the evolution of transport, along with power generation, building design and manufacturing. The continued development of these sectors will need to include changes in energy sources, energy delivery, materials, infrastructure and human behavior. Pathways to reducing carbon from the transport sector have unique challenges and opportunities that are inherent to the human choices and behavioral patterns that mold the transportation systems and the associated energy needs. Technology, government investment, and regulatory policies have a significant impact on the formulation of transportation infrastructure; however, the role of human behavior and public acceptance on the efficiency and effectiveness of transport systems should not be underestimated. Although developed, rapidly developing, and underdeveloped nations face different challenges in the establishment of transport infrastructure that can meet transport needs while achieving sustainable carbon dioxide emissions, the constraints that establish the domain of possibilities are closely related for all nations. These constraints include capital investment, fuel supplies, power systems, and human behavior. Throughout the world, there are considerable efforts directed at advancing and optimizing the financing of sustainable infrastructures, the production of low carbon fuels, and the production of advanced power systems, but the foundational work on methods to understand human preferences and behavior within the context of transport and the valuation of reductions in carbon dioxide emissions is greatly lagging behind. These methods and the associated understanding of human behavior and the willingness to pay for

    The aim of this study is to analyse the evolution of the municipal solid waste management system of João Pessoa (Brazil), which was one of the Brazilian pioneers cities in implementing door-to-door selective collection programmes, in order to analyse the effect of policy decisions adopted in last decade with regard to selective collection. To do it, this study focuses on analysing the evolution, from 2005 to 2015, of the environmental performance of the municipal solid waste management (MSWM) system implemented in different sorting units with selective collection programmes by applying the Life Cycle Assessment (LCA) methodology and using as a starting point data collected directly from the different stakeholders involved in the MSWM system. This article presents the temporal evolution of environmental indicators measuring the environmental performance of the MSWM system implemented in João Pessoa by sorting unit, for each stage of the life cycle of the waste (collection, classification, intermediate transports, recycling and landfilling), for each waste fraction and for each collection method (selective collection or mixed collection), with the aim of identifying the key aspects with the greatest environmental impact and their causes. Results show on one hand, that environmental behaviour of waste management in a door-to-door selective collection programme significantly improves the behaviour of the overall waste management system. Consequently, the potential to reduce the existing environmental impact based on citizens' increased participation in selective collection is evidenced, so the implementation of awareness-raising campaigns should be one of the main issues of the next policies on solid waste. On the other hand, increasing the amount of recyclable wastes collected selectively, implementing alternative methods for valorising the organic fraction (compost/biomethanization) and improving the efficiency of the transportation stage by means of optimizing

    MONJU is a prototype fast breeder reactor (FBR). Modification work commenced in March 2005. Since June 2004, MONJU has changed to one-loop operation of the primary heat transport system (PHTS) with all of the secondary heat transport systems (SHTS) drained of sodium. The purposes of this change are to shorten the modification period and to reduce the cost incurred for circuit trace heating electrical consumption. Before changing condition, the following issues were investigated to show that this mode of operation was possible. The heat loss from the reactor vessel and the single primary loop must exceed the decay heat by an acceptable margin but the capacity of pre-heaters to keep the sodium within the primary vessel at about 200 deg. C must be maintained. With regard to the heat loss and the decay heat, the estimated heat loss in the primary system was in the range of 90-170 kW in one-loop operation, and the calculated decay heat was 21.2 kW. Although the heat input of the primary pump was considered, it was clear that circuit heat loss greatly exceeded the decay heat. As for pre-heaters, effective capacity was less than the heat loss. Therefore, the temperature of the reactor vessel room was raised to reduce the heat loss. One-loop operation of the PHTS was able to be executed by means of these measures. The cost of electrical consumption in the power plant has been reduced by one-loop operation of the PHTS and the modification period was shortened. (authors)

  4. Natural hazard impacts on transport systems: analyzing the data base of transport accidents in Russia

    Science.gov (United States)

    Petrova, Elena

    2015-04-01

    We consider a transport accident as any accident that occurs during transportation of people and goods. It comprises of accidents involving air, road, rail, water, and pipeline transport. With over 1.2 million people killed each year, road accidents are one of the world's leading causes of death; another 20-50 million people are injured each year on the world's roads while walking, cycling, or driving. Transport accidents of other types including air, rail, and water transport accidents are not as numerous as road crashes, but the relative risk of each accident is much higher because of the higher number of people killed and injured per accident. Pipeline ruptures cause large damages to the environment. That is why safety and security are of primary concern for any transport system. The transport system of the Russian Federation (RF) is one of the most extensive in the world. It includes 1,283,000 km of public roads, more than 600,000 km of airlines, more than 200,000 km of gas, oil, and product pipelines, 115,000 km of inland waterways, and 87,000 km of railways. The transport system, especially the transport infrastructure of the country is exposed to impacts of various natural hazards and weather extremes such as heavy rains, snowfalls, snowdrifts, floods, earthquakes, volcanic eruptions, landslides, snow avalanches, debris flows, rock falls, fog or icing roads, and other natural factors that additionally trigger many accidents. In June 2014, the Ministry of Transport of the RF has compiled a new version of the Transport Strategy of the RF up to 2030. Among of the key pillars of the Strategy are to increase the safety of the transport system and to reduce negative environmental impacts. Using the data base of technological accidents that was created by the author, the study investigates temporal variations and regional differences of the transport accidents' risk within the Russian federal regions and a contribution of natural factors to occurrences of different

    Nonreciprocal response is a consequence of the inversion symmetry breaking where lots of physical responses have directivity. This is essentially a non-linear response like a circular dichroism and second harmonic generation in non-linear optics. The electrical resistivity, which is the most fundamental physical property of materials, also shows the nonreciprocity; the resistivity depends on the direction of the current. In this study, we have investigated the nonreciprocal electrical transport in polar semiconductor BiTeBr which has simple Rashba-type band structure. The measured nonreciprocity for this material is quantitatively reproduced by simple model; single relaxation time Boltzmann equation for Rashba Hamiltonian with in-plane Zeeman field. In this presentation, we explain mainly about the theoretical model and the analysis of the nonreciprocal electrical transport.

  7. Transport and Dynamics in Toroidal Fusion Systems

    Sovinec, Carl

    2016-01-01

    The study entitled, 'Transport and Dynamics in Toroidal Fusion Systems,' (TDTFS) applied analytical theory and numerical computation to investigate topics of importance to confining plasma, the fourth state of matter, with magnetic fields. A central focus of the work is how non-thermal components of the ion particle distribution affect the 'sawtooth' collective oscillation in the core of the tokamak magnetic configuration. Previous experimental and analytical research had shown and described how the oscillation frequency decreases and amplitude increases, leading to 'monster' or 'giant' sawteeth, when the non-thermal component is increased by injecting particle beams or by exciting ions with imposed electromagnetic waves. The TDTFS study applied numerical computation to self-consistently simulate the interaction between macroscopic collective plasma dynamics and the non-thermal particles. The modeling used the NIMROD code [Sovinec, Glasser, Gianakon, et al., J. Comput. Phys. 195, 355 (2004)] with the energetic component represented by simulation particles [Kim, Parker, Sovinec, and the NIMROD Team, Comput. Phys. Commun. 164, 448 (2004)]. The computations found decreasing growth rates for the instability that drives the oscillations, but they were ultimately limited from achieving experimentally relevant parameters due to computational practicalities. Nonetheless, this effort provided valuable lessons for integrated simulation of macroscopic plasma dynamics. It also motivated an investigation of the applicability of fluid-based modeling to the ion temperature gradient instability, leading to the journal publication [Schnack, Cheng, Barnes, and Parker, Phys. Plasmas 20, 062106 (2013)]. Apart from the tokamak-specific topics, the TDTFS study also addressed topics in the basic physics of magnetized plasma and in the dynamics of the reversed-field pinch (RFP) configuration. The basic physics work contributed to a study of two

    The final transport and focusing of the heavy-ion beam onto the fusion pellet in vacuum is complicated by several non-linear effects - namely, chromatic (momentum dependent) effects, geometric aberrations, and space-charge forces. This paper gives an example of how the chromatic effects can be nullified, at least to second order. Whether third- or higher-order terms are important is not yet clear. Space-charge effects are important but are not considered here

  18. Making tenofovir accessible in the brazilian public health system: patent conflicts and generic production.

    Science.gov (United States)

    Veras, Juliana

    2014-08-01

    In May 2011, the Brazilian Ministry of Health announced the distribution of the first batch of locally produced generic tenofovir disoproxil fumarate (TDF) to support its program of universal and free access for the treatment of HIV/AIDS. The inclusion of TDF in the public health program illustrates what has been considered the 'Brazilian model' of HIV/AIDS response, as it illustrates the current phase of the Brazilian pharmaceutical economy. Brazil is known for having managed to control the expansion of HIV/AIDS through a unique initiative combining the public health and the industrial production of generics. But, if at first local manufacturers could freely copy ARVs and produce cheaper generic versions that were delivered to the Ministry of Health, since the country started to grant patents on drugs in 1996, the sustainability of this policy has been challenged by the high cost of patented second-line HIV/AIDS treatments. In order to assure continuity of the local production of ARVs, and keep the program of public health alive, Brazilians are now forced to deal with conflicts of drugs' intellectual property rights in order to open the path to generic production. This article aims to describe the experiences surrounding TDF in Brazil and the unprecedented conflicts and challenges it has brought for our different interviewees. Blurring the frontier between the public and the private, the TDF case was driven at the same time by an ethic of drug access and regulation of drug quality, which has inspired Brazilians to intervene and transform the world they live in. © 2014 John Wiley & Sons Ltd.

    Substantial effort has been expended concerning the level of safety provided to persons, property, and the environment from the hazards associated with transporting radioactive material. This work provided an impetus for the Department of Energy to investigate the use of probabilistic risk assessment techniques to supplement the deterministic approach to transportation safety. The DOE recently decided to incorporate the methodologies associated with PRAs in the process for authorizing the transportation of nuclear components, special assemblies, and radioactive materials affiliated with the DOE Defense Program. Accordingly, the LLNL, sponsored by the DOE/AL, is tasked with developing a safety guide series to provide guidance to preparers performing a transportation system risk assessment

  20. Solutions to Improve Person Transport System in the Pitesti City by Analyzing Public Transport vs. Private Transport

    2017-10-01

    One of the major problems facing the Pitesti city is the road congestion that occurs in the central area of the city during the peak hours. With all the measures taken in recent years - the widening of road arteries, increasing the number of parking spaces, the creation of overground road passages - it is obvious that the problem can only be solved by a new philosophy regarding urban mobility: it is no longer possible to continue through solutions to increase the accessibility of the central area of the city, but it is necessary, on the contrary, to promote a policy of discouraging the penetration of vehicles in the city center, coupled with a policy of improving the connection between urban public transport and county public transport. This new approach is also proposed in the new Urban Mobility Plan of Pitesti city, under development. The most convincing argument for the necessity of this new orientation in the Pitesti city mobility plan is based on the analysis of the current situation of passenger transport on the territory of Pitesti city: the analysis of “public transport versus private transport” reveals a very low occupancy rate for cars and the fact that the road surface required for a passenger (the dynamic area) is much higher in the case of private transport than in the case of public transport. Measurements of passenger flows and vehicle flows on the 6 penetration ways in the city have been made and the calculations clearly demonstrate the benefits of an urban public transport system connected by “transshipment buses” to be made at the edge of the city, to the county public transport system. In terms of inter-county transport, it will continue to be connected to the urban public transport system by existing bus Station, within the city: South Bus Station and North Bus Station. The usefulness of the paper is that it identifies the solutions for sustainable mobility in Pitesti city and proposes concrete solutions for the development of the

    Ward, T.R.; Spooner, R.

    1991-01-01

    The Department of Energy (DOE) has developed an integrated transportation system to transport transuranic (TRU) waste from ten widely dispersed generator sites to the Waste Isolation Pilot Plant (WIPP). The system consists of a Type B container, a specially designed trailer, a lightweight tractor, the DOE TRANSCOM satellite-based vehicle tracking system, and uniquely qualified and highly trained drivers. The DOE has demonstrated that this system is ready to transport the TRU waste to the WIPP site efficiently and safely. Since the system was put in place in November 1988, it has been repeatedly upgraded and enhanced to incorporate additional safety measures. In June of 1989, the National Academy of Sciences (NAS) reviewed the transportation system and concluded that ''the system proposed for transportation of TRU waste to WIPP is safer than that employed for any other hazardous material in the United States today and will reduce risk to very low levels'' (emphasis added). The NAS conclusion was made before the DOE implemented the Enhanced Driver Training Course for carrier drivers. The challenge facing the DOE was to examine the transportation system objectively and determine what additional improvements could be made to further enhance safety

    The authors review percutaneous coronary intervention (PCI) evolution and its growing application in myocardial revascularization for patients with coronary heart disease in Brazil and worldwide. PCI was introduced in 1977 using only the catheter balloon. Limitations of this method (acute occlusion and coronary restenosis) led to the adoption of coronary stents and more recently the advent of drug-eluting stents2, which were developed to drastically reduce restenosis rates. These developments allowed the exponential growth of percutaneous coronary intervention (PCI) procedures in Brazil which have replaced many bypass surgery procedures and have become the gold standard for the majority of symptomatic patients suffering from coronary artery disease. The preference for this procedure gained new dimensions in 2000 when the Brazilian Public Healthcare System (SUS) began reimbursing for stent procedures. This measure exemplified the importance of the Public Healthcare System's participation in incorporating medical advances and offering a high standard of cardiovascular treatment to a large portion of the Brazilian population. It is emphasized that prevention of in-stent restenosis is complex due to its unpredictable and ubiquitous occurrence. Control of this condition improves quality of life and reduces the recurrence of angina pectoris, the need to perform new revascularization procedures and hospital readmissions. The overall success of the drug-eluting stents has proven to be reliable and consistent in overcoming restenosis and has some beneficial impact for all clinical and angiographic conditions. This paper discusses the adoption and criteria for the use of drug-eluting stents in other countries as well as the recommendations established by the Brazilian Society of Interventional Cardiology for their reimbursement by SUS. The incorporation of new healthcare technology involves two distinct stages. During the first stage, the product is registered with the

    Full Text Available This study verifies the impact caused by the processes of globalization and convergence to international accounting standards on the managerial control systems of the largest multiple banks that operate in Brazil. The study was exploratory in nature, with the use of the case study method and the application of questionnaires containing mostly open questions to upper tier executives of four major Brazilian banks. The analysis showed that globalization has resulted in improved control systems and widespread use of information technology. It was also found that the convergence to international accounting standards occurred properly, thanks to the steps taken by the Central Bank that aimed at an agile updating of the Brazilian accounting standards laid down for banks operating in Brazil, in line with international standards. In general, the researched banks did not report a significant impact of convergence to the IFRS on their management control systems; adherence to the international accounting standards has had more significant impacts on information systems, especially regarding the new reporting and transparency standards, rather than on management controls. This result signals that the management control systems of the four banks in the sample are in line with Anthony (1965’s vision, that is, that flexibility to adapt to every change in the external environment might actually increase risks of failure.

    To characterize the use of medicines by patients of the primary health care of the Brazilian Unified Health System (SUS). This is a cross-sectional, exploratory, and descriptive study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). Interviews were carried out with patients present in the services by semi-structured questionnaires. Sociodemographic, clinical, and use of medicines variables were assessed and the use of medicines in the 30 days prior to the interview was also verified. The population was stratified into three age groups: 18 to 44, 45 to 64, and 65 years or more. The differences between the age groups were verified using the Student's t-test for continuous variables and chi-square test for the categorical ones. The complex samples analysis plan was employed. The medicines were classified according to the Anatomical Therapeutic Chemical Classification System. Of the 8,803 patients interviewed, 6,511 (76.2%) reported to have used medicines in the 30 days prior to the interview. On average, each patient used 2.32 medicines, without difference between the sexes. Among medicine users, 18.2% were aged 65 years or more. Compared to the other age groups, older adults presented more comorbidities, used more medicines, and self-reported worse health conditions. They were also less educated, reported worse economic situation, and lived alone. The medicines that were mostly used were "other analgesics and antipyretics" (3rd ATC level) and Losartan (5th ATC level). Most medicine users had lower education level and presented comorbidities. The most used medicines were the antihypertensive ones. Self-medication was higher among young people. Most patients reported to use generic medicines. The average number of medicines and the prevalence of use increased with age. Due to the characteristics

    The maintenance of limnological monitoring programs in the Cerrado Domain is crucial as a provision of useful information about temporal variations in land use and their respective water quality responses, considering its importance as water source for different Brazilian hydrographic basins. The purpose of this research was to describe limnological variables of low-order lotic systems located in the Cerrado Long Term Ecological Research (LTER) site (Environmental Protection Area (APA) Gama and Cabeça de Veado, Federal District of Brazil). Altogether, nine different streams were considered in this study. Samplings were conducted between 2010 and 2012, concentrated in the dry and rainy seasons. The sampling sites were generally characterized by low nutrient concentrations (e.g., medians, TP = 14.8 μg L(-1), TN = 20.0 μg L(-1), NO3 = 13.8 μg L(-1)) and slightly acidic waters (median, pH = 5.3), with quite low electrical conductivity values (median = 6.4 μS cm(-1)). However, water quality degradation as a response to diffuse pollution was reported in some sampling points (e.g., Onça and Gama streams), expressed by relatively higher N and P concentrations, which were probably highlighted by the good water quality of the data set as whole. Although there was a trend to higher values of nitrogen forms during the dry season, significant statistical differences between the seasonal periods were reported only for the variables temperature and dissolved silica, which were higher in the dry and rainy season, respectively. The streams located in the preserved areas inside the ecological stations of APA Gama and Cabeça de Veado can still be considered good examples of reference lotic systems in the Cerrado Domain; notwithstanding, this study reported incipient signs of water quality degradation which cannot be overlooked in future limnological monitoring.

    The Brazilian health reform process, following the establishment of the Unified Health System (SUS), has had a strong emphasis on decentralization, with a special focus on financing, management and inter-managerial agreements. Brazil is a federal country and the Ministry of Health (MoH), through the Secretary of Labour Management and Health Education, is responsible for establishing national policy guidelines for health labour management, and also for implementing strategies for the decentralization of management of labour and education in the federal states. This paper assesses whether the process of decentralizing human resources for health (HRH) management and organization to the level of the state and municipal health departments has involved investments in technical, political and financial resources at the national level. The research methods used comprise a survey of HRH managers of states and major municipalities (including capitals) and focus groups with these HRH managers - all by geographic region. The results were obtained by combining survey and focus group data, and also through triangulation with the results of previous research. The results of this evaluation showed the evolution policy, previously restricted to the field of 'personnel administration', now expanded to a conceptual model for health labour management and education-- identifying progress, setbacks, critical issues and challenges for the consolidation of the decentralized model for HRH management. The results showed that 76.3% of the health departments have an HRH unit. It was observed that 63.2% have an HRH information system. However, in most health departments, the HRH unit uses only the payroll and administrative records as data sources. Concerning education in health, 67.6% of the HRH managers mentioned existing cooperation with educational and teaching institutions for training and/or specialization of health workers. Among them, specialization courses account for 61.4% and short

    The U.S. Department of Energy (DOE) Transportation Management Division (TMD) is responsible for managing its various programs via a diverse combination of Government-Owned/Contractor-Operated facilities. TMD is seeking to update it automation capabilities in capturing and processing DOE transportation information. TMD's Transportation Information Network (TIN) is an attempt to bring together transportation management, shipment tracking, research activities and software products in various stages of development. The TMD's Automated Transportation Management System (ATMS) proposes to assist the DOE and its contractors in performing their daily transportation management activities and to assist the DOE Environmental Management Division in its waste management responsibilities throughout the DOE complex. The ATMS system will center about the storage, handling and documentation involved in the environmental clean-up of DOE sites. Waste shipments will be moved to approved Treatment, Storage and Disposal (TSD) facilities and/or nuclear material repositories. An additional investment in shipping samples to analytical laboratories also involves packaging and documentation according to all applicable U.S. Department of Transportation (DOT) or International Air Transport Association (IATA) regulations. The most immediate goal of effectively managing DOE transportation management functions during the 1990's is an increase in automation capabilities of the DOE and its contractors. Subject-matter experts from various DOE site locations will be brought together to develop and refine these capabilities through the maximum use of computer applications. A major part of this effort will be the identification of the most economical modes of transportation and enhanced management reporting capabilities for transportation analysis. The ATMS system will also provide for increased strategic and shipment analysis during the 1990's and beyond in support of the DOE environmental mission

    Full Text Available Waste collection is an important municipal service that charges large expenditures to waste management (WM system. In this study, a hierarchical structure is proposed in order to minimize total cost of waste collection routing problem. Moreover, in second stage destructive environmental effects of waste transportation are minimized concurrently through taking advantage of a road/rail transportation system. In the proposed multimodal transportation system, waste packs are transferred to final destination while travel time and risk of environmental threatening is minimized. The discussed problem is formulated mathematically in two stages. In the first stage, a household waste collection routing problem is formulated while, in second stage a multimodal transportation system is routed to transfer waste packs to final destination through roads and railroads. In order to solve the proposed NP hard models, an improved genetic algorithm is developed. Comparison of the obtained results with those of GAMS for small-size samples validates the proposed models.

    In March 1987, the US Department of Energy presented to Congress the proposal to construct and operate a facility for the monitored retrievable storage (MRS) of spent fuel at a site on the Clinch River in the Roane County portions of Oak Ridge. In discussing the MRS to Transportation System Interfaces, the authors provide a blending of the technical and institutional issues, for they do not believe the solutions to success of this enterprise lie wholly in one area. The authors cover: early chronology of the MRS; comparison of total-system life cycle cost estimates of the authorized system and improved-performance system (i.e., the system that includes a facility for MRS); transportation costs resulting from shipping, security and cask; assumptions for dedicated rail transport from MRS to repository; and significant results from the Total System Life Cycle Cost (TSLCC) analysis of the improved performance system.

    national soil classification was presented by Marcelo Camargo (Embrapa Soils) and Jacob Bennema (FAO adviser). When Soil Taxonomy was first published in 1975, a field workshop was held in Brazil, and the system was not accepted by the country scientists; one main reason was the usage of climate as a main attribute for suborders. In 1978, the first national soil field correlation meeting was held with the goal of developing the national system, giving origin to the Brazilian Soil Classification System (SiBCS). In 1980, a working group was created by Embrapa Soils and other institutes resulting in four approximations of the system. In 1999, the first edition of the SiBCS was released, followed by a second edition in 2006 and the third in 2013. The SiBCS is a hierarchic system, based on morphogenetic soil attributes, with six categorical levels: order, suborder, great group, subgroup, family, and series. It has 13 soil orders, and it is structured as a key down to subgroup level. Many soil attributes are based on concepts adopted by the Soil Taxonomy (United States) and by the World Reference Base for Soil Resources (WRB - FAO). The development of the SiBCS is supervised by a national executive committee, and information is available at http://www.cnps.embrapa.br/sibcs (in Portuguese).

    Full Text Available There are many ethical discussions about the use of placebo in research with humans. These discussions often occur from a bioethical standpoint, particularly in the light of the bioethical principles of autonomy, justice and equity. However, and without disregarding the impor-tance of these discussions, the legal aspect should also be considered, particularly concerning medical research with commercial purposes. This article, from a literature interdisciplinary review, aims to discuss, in the light of the Brazilian legal system, how research using placebo and financed by laboratories and pharmaceutical companies should be tackled and how to assess the liability arising from this research in case of damage caused to the participants.

    We present a new version of the Brazilian developments on the Regional Atmospheric Modeling System where different previous versions for weather, chemistry and carbon cycle were unified in a single integrated software system. The new version also has a new set of state-of-the-art physical parameterizations and greater computational parallel and memory usage efficiency. Together with the description of the main features are examples of the quality of the transport scheme for scalars, radiative fluxes on surface and model simulation of rainfall systems over South America in different spatial resolutions using a scale-aware convective parameterization. Besides, the simulation of the diurnal cycle of the convection and carbon dioxide concentration over the Amazon Basin, as well as carbon dioxide fluxes from biogenic processes over a large portion of South America are shown. Atmospheric chemistry examples present model performance in simulating near-surface carbon monoxide and ozone in Amazon Basin and Rio de Janeiro megacity. For tracer transport and dispersion, it is demonstrated the model capabilities to simulate the volcanic ash 3-d redistribution associated with the eruption of a Chilean volcano. Then, the gain of computational efficiency is described with some details. BRAMS has been applied for research and operational forecasting mainly in South America. Model results from the operational weather forecast of BRAMS on 5 km grid spacing in the Center for Weather Forecasting and Climate Studies, INPE/Brazil, since 2013 are used to quantify the model skill of near surface variables and rainfall. The scores show the reliability of BRAMS for the tropical and subtropical areas of South America. Requirements for keeping this modeling system competitive regarding on its functionalities and skills are discussed. At last, we highlight the relevant contribution of this work on the building up of a South American community of model developers.

    Full Text Available To examine changes in the time spent in each mode of transportation used for going to school by gender and age among adolescents from Santa Catarina State, Brazil. Two school-based surveys were performed in 2001 (N = 5,028 and 2011 (N = 6,529 in high school students (15-19 years old. The mode of transportation (on foot; by bicycle; by bus; car/motorcycle and the time spent for commuting to school were assessed. Active commuting increased for short trips in both genders (male: 25.1% to 36.7%; female: 18.8% to 29.2% and in all ages (15-16 years: 21% to 32.7%; 17-19 years: 21.9% to 32.4%, and declined for longer trips in males (30.5% to 21.9% and in 15-16 years old students (25.7% to 34.7%. Car/motorcycle use has doubled for short trips in males (38.1% to 65.9% and in 17-19 years old students (37.7% to 62.7%, while the use of buses remained stable in both genders. Our findings contribute to discussions on public policy focusing on the design of safe environments to promote active commuting to schools, particularly to decrease the use of motorized transport for short trips.

    Main parameters and advantages of pneumatically operated systems, primarily those operated by gas pressure are discussed. The special irradiation ends for the TRIGA reactor are described. To give some idea of the complexity of some modern systems, the author presents the large system currently operating at the National Bureau of Standards in Washington. In this system, 13 stations are located throughout the radiochemistry laboratories and three irradiation ends are located in the reactor, which is a 14-megawatt unit. The system incorporates practically every fail-safe device possible, including ball valves located on all capsule lines entering the reactor area, designed to close automatically in the event of a reactor scram, and at that time capsules within the reactor would be diverted by means of switches located on the inside of the reactor wall. The whole system is under final control of a permission control panel located in the reactor control room. Many other safety accessories of the system are described

    To evaluate the access to medicines in primary health care of the Brazilian Unified Health System (SUS), from the patients' perspective. This is a cross-sectional study that used data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Services, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), conducted by interviews with 8,591 patients in cities of the five regions of Brazil. Evaluation of access to medicines used concepts proposed by Penshansky and Thomas (1981), according to the dimensions: availability, accessibility, accommodation, acceptability, and affordability. Each dimension was evaluated by its own indicators. For the "availability" dimension, 59.8% of patients reported having full access to medicines, without significant difference between regions. For "accessibility," 60% of patients declared that the basic health unit (UBS) was not far from their house, 83% said it was very easy/easy to get to the UBS, and most patients reported that they go walking (64.5%). For "accommodation," UBS was evaluated as very good/good for the items "comfort" (74.2%) and "cleanliness" (90.9%), and 70.8% of patients reported that they do not wait to receive their medicines, although the average waiting time was 32.9 minutes. For "acceptability," 93.1% of patients reported to be served with respect and courtesy by the staff of the dispensing units and 90.5% declared that the units' service was very good/good. For "affordability," 13% of patients reported not being able to buy something important to cover expenses with health problems, and 41.8% of participants pointed out the expense with medicines. Results show 70%-90% compliance, which is compatible with developed countries. However, access to medicines remains a challenge, because it is still heavily compromised by the low availability of essential medicines in public health units, showing that it does not occur universally, equally

Maglev represents the latest evolution in very high and speed ground transportation, where vehicles are magnetically levitated, guided, and propelled over elevated guideways at speeds of 300 miles per hour. Maglev is not a new concept but is, however, receiving renewed interest. The objective of this workshop was to further promote these interest by bringing together a small group of specialists in Maglev technology to discuss Maglev research needs and to identify key research issues to the development of a successful Maglev system. The workshop was organized into four sessions based on the following technical areas: Materials, Testing, and Shielding; Magnet Design and Cryogenic Systems; Propulsion and Levitation Systems; and, System Control and Integration.

    1988-01-01

    The concept for the underground transportation and handling system for Pollux-casks was optimized in a first phase by dividing the process in the repository up into the several transportation and manipulation steps. For each step, the possibilities were described and evaluated by means of a list of criteria (technical, safety and economical criteria). The following concept for the transportation and handling was developed: The casks are transported to the unloading area of the surface facilities by railway or truck. After removal of the transport protection, the entry control is performed. The cask is lifted from the vehicle and placed on a railbound transportation vehicle. This transport unit is transferred to the shaft and placed there ready for shaft hoisting. With the hoisting cage protruding, the transport unit is placed on the hoisting cage by means of a pushing-on device, locked, and then conveyed underground. After arrival on the emplacement level, the transport unit is pulled-off from the hoisting cage and taken over by a mine locomotive and transferred through the transportation and access drifts as far as to the emplacement site. There the locomotive pushed the rail transport vehicle into the emplacement drift, as far as to the designated emplacement position. At the emplacement position, the cask is again lifted by means of hoisting equipment. The rail transport vehicle is pulled out of the emplacement drift and returned to the surface for reloading. After deposition of the cask on the drift floor, the emplacement equipment is pulled back in order to give the operation space free for the slinger backfill truck. Within preceding tests two different backfilling techniques were investigated under realistic conditions: pneumatic backfilling and slinger backfilling. The slinger truck was found to be the most suitable for the designated purpose

    Full Text Available This paper investigates the effect of freight transport time savings (FTTS on the performance of transport consuming companies. In the first part existing methods on FTTS valuation are critically discussed and their limitations are identified. Following, a conceptual model is built introducing an alternative approach for the valuation of FTTS that is based on the system perspective of firms, integrating the disciplines of systems thinking, performance measurement, transport and logistics decision making. Evidence from a Systems Dynamics’ simulation experiment on a retailer suggests that the effect of FTTS on performance depends highly on the structure of the firm's transport related processes and decision making process. Through the development and simulation of several scenarios concerning the reaction of the firm to the FTTS, it is concluded that the value of FTTS is sensitive to the type of the reaction and its time profile.

  17. TERLIPRESSIN VERSUS NORADRENALINE FOR HEPATORENAL SYNDROME. Economic evaluation under the perspective of the Brazilian Public Health System

    Ângelo Zambam de MATTOS

    Full Text Available ABSTRACT Background - Terlipressin and noradrenaline are the best studied treatments for hepatorenal syndrome, and there is no evidence of superiority of one over the other regarding to efficacy. While the former drug is more costly, the latter requires admission into an intensive care unit. Objective - The aim of this study was to perform an economic evaluation, comparing treatments for hepatorenal syndrome with terlipressin and noradrenaline. Methods - For the economic evaluation, a cost-minimization analysis was performed. Direct medical costs of the two treatment strategies were compared under the perspective of the Brazilian Public Health System as the third-party payer. A probabilistic sensitivity analysis was performed. Results - The costs of treatments with terlipressin or noradrenaline were 287.77 and 2,960.45 International Dollars (Int$ respectively. Treatment using terlipressin would save Int$2,672.68 for the Public Health System for each hospital admission related to hepatorenal syndrome. In the probabilistic sensitivity analysis, it was verified that the cost of the treatment with noradrenaline could vary between Int$2,326.53 and Int$3,644.16, while costs related to the treatment using terlipressin are not variable. Conclusion - The treatment strategy using terlipressin was more economical than that using noradrenaline under the perspective of the Brazilian Public Health System as the third-party payer.

    Full Text Available The development of signal transmitting environment for multimodal traffic control will enhance the integration of emergency and specialized transport routing tools in usual traffic control paradigms - it is one of the opportunities offered by modern intelligent traffic control systems. The improvement of effective electric power use in public transport system is an advantage of Intelligent Transport System (ITS. The research is connected with the improvement of on-line traffic control and adaptation of special traffic lighting alternatives by ITS. The assignment of the nearest appropriate transport will be done by passenger request, but unlike information system, the transport planning is done on demand. The task can be solved with the help of modern technical methods and equipment, as well as by applying control paradigms of the distributed systems. The problem is solved with the help of calculations hyper-graph and scheduling theory. The goal of the research is to develop methods, which support scheduling of the emergency transport, using high performance computing.

    Full Text Available The formation of a thermal microclimate within the vehicle during the transport of broilers from farm to slaughterhouse affects the birds' welfare and potentially promotes the development of PSE meat. Thus, the aim of this work was to evaluate the effects of routine commercial practices on the vehicle microclimate formed during transportation of broilers. Twenty-four hours postmortem Pectoralis major m. samples were classified as PSE meat by determining pH and color (L*, a* e b*. Results showed that broiler located at the rear of the truck and with longer journey presented higher amounts of PSE meat because birds were under harsh conditions of both temperature and relative humidity. The ventilation decreased gradually from the front to the rear of the truck, and the water bath at the farm was beneficial over a long distance by reducing the overall occurrence of PSE meat.O microambiente térmico formado no caminhão de transporte de frangos da granja ao abatedouro pode ser a causa primária que compromete o bem estar das aves e a qualidade final da carne com o desenvolvimento de PSE (Pale, Soft, Exudative em filés de peito de frango. O objetivo deste trabalho foi avaliar o efeito do microambiente formado durante o transporte por caminhão em uma linha comercial. Para classificação de filés de peito em PSE, o pH e a cor (L*, a* e b* foram medidos nos filés de peito de frango 24 h postmortem. Os resultados mostraram que em jornadas longas, as aves transportadas nas regiões do meio e fundo do veículo apresentaram maior ocorrência de PSE devido às drámaticas condições de temperatura e umidade relativa no microambiente destas regiões. A ventilação diminuiu gradualmente da frente à trazeira do caminhão e a aplicação do banho de água sobre os frangos após o carregamento na granja foi benéfica em jornadas longas ao reduzir a ocorrência de carnes PSE.

    Cells use transporters of different affinities to regulate nutrient influx. When nutrients are depleted, low-affinity transporters are replaced by high-affinity ones. High-affinity transporters are helpful when concentrations of nutrients are low, but the advantage of reducing their abundance when nutrients are abundant is less clear. When we eliminated such reduced production of the Saccharomyces cerevisiae high-affinity transporters for phosphate and zinc, the elapsed time from the initiation of the starvation program until the lack of nutrients limited growth was shortened, and recovery from starvation was delayed. The latter phenotype was rescued by constitutive activation of the starvation program. Dual-transporter systems appear to prolong preparation for starvation and to facilitate subsequent recovery, which may optimize sensing of nutrient depletion by integrating internal and external information about nutrient availability.

    ABSTRACT: Knowledge of ion-conduction mechanisms in polymers is important for designing better polymer electrolytes for electrochemical devices. In this work, chitosan-ethylene carbonate/propylene carbonate (chitosan-EC/PC) system with lithium acetate (LiCH 3 COO) and lithium triflate (LiCF 3 SO 3 ) as salts were prepared and characterized using electrochemical impedance spectroscopy to study the ion-conduction mechanism. It was found that the electrolyte system using LiCF 3 SO 3 salt had a higher ionic conductivity, greater dielectric constant and dielectric loss value compared to system using LiCH 3 COO at room temperature. Hence, it may be inferred that the system incorporated with LiCF 3 SO 3 dissociated more readily than LiCH 3 COO. Conductivity mechanism for the systems, 42 wt.% chitosan- 28 wt.% LiCF 3 SO 3 -30 wt.% EC/PC (CLT) and 42 wt.% chitosan-28 wt.% LiCH 3 COO-30 wt.% EC/PC (CLA) follows the overlapping large polaron tunneling (OLPT) model. Results show that the nature of anion size influences the ionic conduction of chitosan based polymer electrolytes. The conductivity values of the CLA system are found to be higher than that of CLT system at higher temperatures. This may be due to the vibration of bigger triflate anions would have hindered the lithium ion movements. FTIR results show that lithium ions can form complexation with polymer host which would provide a platform for ion hopping

    Kawasaki Heavy Industries Ltd. has installed an FEL beam transport system at the IR FEL Research Center of the Science University of Tokyo (FEL-SUT). This system transports the FEL output beam from the FEL machine room to the optical diagnostic room through a vacuum tube. The in-vacuum multi-mirror synchronized system operated from the FEL control room enables the operator to control the multiple mirrors simultaneously on or off axis of the FEL beam and to distribute the FEL output to one of the laboratories. The essential component of the transport system is the passive control optics that is composed of an elliptical and parabolic mirror couple. Once the control optics is aligned, a parallel FEL beam with a good pointing stability is obtained without any active operation to tune the optical system for different wavelengths.

    Design and cost studies were performed for the magnet components of mid-size (1-5 MWh), cold supported SMES systems using alternative configurations. The configurations studied included solenoid magnets, which required onsite assembly of the magnet system, and toroid and racetrack configurations which consisted of factory assembled modules. For each configuration, design concepts and cost information were developed for the major features of the magnet system including the conductor, electrical insulation, and structure. These studies showed that for mid-size systems, the costs of solenoid and toroid magnet configurations are comparable and that the specific configuration to be used for a given application should be based upon customer requirements such as limiting stray fields or minimizing risks in development or construction

    2013-06-01

    In this paper, a literature study on risk analysis systems for the transport of hazardous materials was conducted. The insights that resulted from this literature review have led to the development of a refined approach to map the risk of hazmat transport in Flanders based on historical accident data. The proposed framework allows setting up an overall risk map for hazmat transport by different transport modes. Additionally, a methodology to calculate a local accident risk, which takes local infrastructure parameters and accident data into account, is being introduced. In the presented framework one of the general principles is that the risk of a catastrophic hazmat incident can be divided into two parts, which can both be validated on the basis of accident data: (a) the calculation of the general probability of the occurrence of an accident based on international accident data of transport of hazardous materials--this is the basis for the global risk map, and (b) the calculation of the local probability of the occurrence of an accident based on accident data and infrastructure parameters of the complete available freight transport in Flanders--this is the basis for the local risk map. The ratio between these two results in a locality parameter, which represents the local specific circumstances that can lead to an accident. This evaluation framework makes it possible to estimate the risks of hazmat transport along a specific route for transport by road, rail, inland navigation and even pipelines.

    The Princeton Large Torus (PLT) neutral beam injection systems have proven themselves to be a solid foundation on which next generation systems can be based. There are two areas in the new systems receiving particular emphasis: (a) increased power per beam line and (b) higher beam transmission efficiency. Two different methods are being investigated to improve the transmission efficiency. First the drift tube region, the region of the beam line between the vacuum chamber housing the ion source and the torus, is being enlarged. In this manner a second, large cryopump will be installed in the drift tube to lower the pressure to approx.10 -5 torr. Thus, neutral beam reionization on the background gas will be significantly reduced from the measured losses at a few 10 -4 torr of the PLT system. Second, the beam divergence will be reduced by application of one or more of three known techniques developed on a single aperture source in the laboratory. Each of these methods has shown a reduction in single beamlet divergence from theta/sub HWHM/ approx. 1 0 to approx.0.5 0 . The low beamlet divergence coupled with a differentially pumped drift tube will effectively accommodate the larger ion sources under development. All future beam line systems will benefit either directly or indirectly from the experience gained operating and upgrading the PLT beam line concept

    2006-01-01

    This document provides specifications for selected system components of the Transportation, Aging and Disposal (TAD) canister-based system. A list of system specified components and ancillary components are included in Section 1.2. The TAD canister, in conjunction with specialized overpacks will accomplish a number of functions in the management and disposal of spent nuclear fuel. Some of these functions will be accomplished at purchaser sites where commercial spent nuclear fuel (CSNF) is stored, and some will be performed within the Office of Civilian Radioactive Waste Management (OCRWM) transportation and disposal system. This document contains only those requirements unique to applications within Department of Energy's (DOE's) system. DOE recognizes that TAD canisters may have to perform similar functions at purchaser sites. Requirements to meet reactor functions, such as on-site dry storage, handling, and loading for transportation, are expected to be similar to commercially available canister-based systems. This document is intended to be referenced in the license application for the Monitored Geologic Repository (MGR). As such, the requirements cited herein are needed for TAD system use in OCRWM's disposal system. This document contains specifications for the TAD canister, transportation overpack and aging overpack. The remaining components and equipment that are unique to the OCRWM system or for similar purchaser applications will be supplied by others

    The present work identifies, characterizes and analyses the normative requirements for the development and implementation of quality management systems in Brazilian nuclear installations and activities. The requirements established in standards IAEA GS-R-3, IAEA GS-G-3.1, IAEA DS 349, NBR ISO 9001:2000 e CNEN-NN-1.16 are critically analyzed. A correlation matrix of the applicable standards is presented and the related topics among them are identified. The standards IAEA GS-R-3, IAEA GS-G-3.1 and IAEA DS 349 define general requirements for establishing, implementing, assessing and continually improving an integrated management system in nuclear installations and activities, in IAEA member countries. The standard NBR ISO 9001:2000 establishes general requirements for the implementation of a quality management system in all kinds of organizations. The standard CNEN NN-1.16 establishes the regulating requirements for the quality assurance systems and programs of nuclear installations, for licensing and authorization for operation of these installations in Brazil. The standard IAEA GS-R-3 that replaces the code IAEA 50-C-Q introduces the concept of 'Integrated Management System' for the nuclear area, in preference to the concepts of 'Quality Assurance' and 'Quality Management'. This new approach is aligned with the current tendency incorporating requirements of quality, safety, health, environment, security, economics and other in a unique management system. Examples of quality management systems implemented by Brazilian nuclear organizations and by nuclear organizations outside Brazil are analyzed and considered in the discussion of results. (author)

    The problem of groundwater contamination at a large number of industrial facilities is well known. Many US Army and Department of Energy (DOE) facilities share this problem of potentially contaminated water as a result of past disposal practices associated with military and energy source development activities. A wide range of contaminants are found at certain installations encompassing industrial pollutants and military-unique materials. The US Army Biomedical Research and Development Laboratory has been conducting research for a number of years on developing better means to determine the hazards associated with exposure to these types of complex mixtures. The methods involve the use of aquatic organisms together with in vitro mutagenicity assays and analytical chemistry in an integrated biological assessment of a specific site. Integrated Biological Assessment is an important development in the Army's continuing efforts to locate, clean and monitor sites contaminated as a result of military operations. This method provides meaningful hazard data regarding whether a test medium contains low levels of industrial or military-unique contaminants. This is an important advance in determining which sites are clean and which require remediation. It provides continuing monitoring of the effectiveness of remediation operations. Engineering Computer Opteconomics (ECO), Inc. was tasked, in a collaborative Army and DOE effort, to develop a transportable Integrated Biological Assessment Laboratory Complex. This multimodular Complex is designed to be taken into remote areas to provide the necessary long-term on-site research for determining hazards from low levels of contamination in the environment. Each module of the Complex is designed to be self-sufficient, to provide a safe environment for the operators, and a controlled environment for the test organisms and related critical chemical and biological analyses

    The Brookhaven AGS, 807 m in circumference, and the Tandem Van de Graaff are now joined together by a transport line, 600 m in length. This now allows heavy ions from the Tandem, up to fully stripped sulfur (M = 32) to be transported into the AGS and accelerated to 15 GeV/A. With the addition of a booster between the Tandem and the AGS in the near future, heavy ions such as gold (M = 200) can be accelerated to 30 Z/A GeV/A. This paper describes the HITL (Heavy Ion Transport Line) vacuum control system design and implementation

    A nonlinear transport theory for many-body systems arbitrarily away from equilibrium, based on the nonequilibrium statistical operator (NSO) method, is presented. Nonlinear transport equations for a basis set of dynamical quantities are derived using two equivalent treatments that may be considered far reaching generalizations of the Hilbert-Chapman-Enskog method and Mori's generalized Langevin equations method. The first case is considered in some detail and the general characteristics of the theory are discussed. (Author) [pt

    Engineered nanoparticles are making their way into natural environment as a result of a growing nanochemical industry. However, processes that govern the deposition and transport of nanoparticles are yet to be understood and often complicated by technical difficulties in tracing these nanoparticles once they enter into and/or mixed with heterogeneous minerals in the natural environment. In this presentation, we discuss the transport of nanoparticles in heterogeneous systems such as in a mixed colloidal system of silica, ferrihydrite and natural organic matter in the light of new methodologies that may be used for such complicated systems. Transport of heterogeneously charged nanoparticles was investigated in column studies using quartz or iron-oxide-coated quartz as collector surfaces. Monodisperse SiO2 (~40 and ~80 nm) and ferrihydrite (~100 nm) particles and a natural humic acid was used. Results indicate that, even under favorable conditions, ferrihydrite nanoparticles show a conservative transport through oppositely charged quartz media when they coexist with the humic acid or with oppositely charged silica nanoparticles. The ratio of oppositely charged nanoparticles is critical in determining their mobility. Similarly, the transport and detachment of iron oxide nanoparticles from iron oxide- coated quartz were observed when humics were present in the feed solution. Our results imply that transport or co-transport of oppositely charged nanoparticles can occur simultaneously under conditions that are relevant to natural geochemical environment. Further studies are needed to understand detailed mechanisms and processes that govern the deposition and transport of engineered nanoparticles under realistic environmental conditions and in the presence of heterogeneous sediment collectors. New tools such as the used of various labeled nanoparticles (such as fluorescent-labeled nanoparticles) and neutron scattering techniques could be useful in studies of such

  11. Optimal Operation of Interdependent Power Systems and Electrified Transportation Networks

    2018-01-01

    Full Text Available Electrified transportation and power systems are mutually coupled networks. In this paper, a novel framework is developed for interdependent power and transportation networks. Our approach constitutes solving an iterative least cost vehicle routing process, which utilizes the communication of electrified vehicles (EVs with competing charging stations, to exchange data such as electricity price, energy demand, and time of arrival. The EV routing problem is solved to minimize the total cost of travel using the Dijkstra algorithm with the input from EVs battery management system, electricity price from charging stations, powertrain component efficiencies and transportation network traffic conditions. Through the bidirectional communication of EVs with competing charging stations, EVs’ charging demand estimation is done much more accurately. Then the optimal power flow problem is solved for the power system, to find the locational marginal price at load buses where charging stations are connected. Finally, the electricity prices were communicated from the charging stations to the EVs, and the loop is closed. Locational electricity price acts as the shared parameter between the two optimization problems, i.e., optimal power flow and optimal routing problem. Electricity price depends on the power demand, which is affected by the charging of EVs. On the other hand, location of EV charging stations and their different pricing strategies might affect the routing decisions of the EVs. Our novel approach that combines the electrified transportation with power system operation, holds tremendous potential for solving electrified transportation issues and reducing energy costs. The effectiveness of the proposed approach is demonstrated using Shanghai transportation network and IEEE 9-bus test system. The results verify the cost-savings for both power system and transportation networks.

    2016-01-01

    Full Text Available The city of Curitiba, located at Southern Brazil, is recognized by its urban planning structured on three pillars: land use, collective transportation, and traffic. With 3.8 million people in its metropolitan area, the public transport system deals with approximately 2.5 million passengers daily. The structure and properties of such a transportation system have substantial implications for the urban planning and public politics for sustainable development of Curitiba. Therefore, this paper analyzes the structure of the public transportation system of Curitiba through the theory of complex networks in a static approach of network topology and presents a comparative analysis of the results from Curitiba, three cities from China (Shanghai, Beijing, and Guangzhou, and three cities from Poland (GOP, Warszawa, and Łódź. The transportation network was modeled as a complex network with exact geographical coordinates of its bus stops. In all bus lines, the method used was the P-Space. The results show that this bus network has characteristics of both small-world and scale-free networks.

  15. Transformations in Air Transportation Systems For the 21st Century

    Holmes, Bruce J.

    2004-01-01

    Globally, our transportation systems face increasingly discomforting realities: certain of the legacy air and ground infrastructures of the 20th century will not satisfy our 21st century mobility needs. The consequence of inaction is diminished quality of life and economic opportunity for those nations unable to transform from the 20th to 21st century systems. Clearly, new thinking is required regarding business models that cater to consumers value of time, airspace architectures that enable those new business models, and technology strategies for innovating at the system-of-networks level. This lecture proposes a structured way of thinking about transformation from the legacy systems of the 20th century toward new systems for the 21st century. The comparison and contrast between the legacy systems of the 20th century and the transformed systems of the 21st century provides insights into the structure of transformation of air transportation. Where the legacy systems tend to be analog (versus digital), centralized (versus distributed), and scheduled (versus on-demand) for example, transformed 21st century systems become capable of scalability through technological, business, and policy innovations. Where air mobility in our legacy systems of the 20th century brought economic opportunity and quality of life to large service markets, transformed air mobility of the 21st century becomes more equitable available to ever-thinner and widely distributed populations. Several technological developments in the traditional aircraft disciplines as well as in communication, navigation, surveillance and information systems create new foundations for 21st thinking about air transportation. One of the technological developments of importance arises from complexity science and modern network theory. Scale-free (i.e., scalable) networks represent a promising concept space for modeling airspace system architectures, and for assessing network performance in terms of robustness

    Full Text Available The paper presents radical new urban transportation system concepts, potentially allowing changing the economic and environmental costs of passenger and freight transportation. The driver focuses on the concept of sharing, which means to make a joint use of transport resources, between passengers and goods flows. From a field observation of several existing solutions, an inductive reasoning enables us to move from a set of specific facts to establish an archetype for a radical new urban transportation system. Once the archetype defined, it is translated in real life through the example of the On Route proposal for London.The research frame of this paper is the ANR ( French National Research Agency C-Goods (City Goods Operation Optimization using Decision support System project.

    Civil and military applications of space transportation have been pursued for just over 50 years and there has been, and still is, a need for safe, dependable, affordable, and sustainable space transportation systems. Fully expendable and partially reusable space transportation systems have been developed and put in operation that have not adequately achieved this need. Access to space is technically achievable, but presently very expensive and will remain so until there is a breakthrough in the way we do business. Since 1991 the national Space Propulsion Synergy Team (SPST) has reviewed and assessed the lessons learned from the major U.S. space programs of the past decades focusing on what has been learned from the assessment and control of Life Cycle Cost (LCC) from these systems. This paper presents the results of a selected number of studies and analyses that have been conducted by the SPST addressing the need, as well as the solutions, for improvement in LCC. The major emphasis of the SPST processes is on developing the space transportation system requirements first (up front). These requirements must include both the usual system flight performance requirements and also the system functional requirements, including the infrastructure on Earth's surface, in-space and on the Moon and Mars surfaces to determine LCC. This paper describes the development of specific innovative engineering and management approaches and processes. This includes a focus on flight hardware maturity for reliability, ground operations approaches, and business processes between contractor and government organizations. A major change in program/project cost control is being proposed by the SPST to achieve a sustainable space transportation system LCC - controlling cost as a program metric in addition to the existing practice of controlling performance and weight. Without a firm requirement and methodically structured cost control, it is unlikely that an affordable and sustainable space

    TRANSPORT is a first- and second-order matrix multiplication computer program intended for the design of static-magnetic beam transport systems. It has been in existence in various evolutionary versions since 1963. The present version, described in the manual given, includes both first- and second-order fitting capabilities. TRANSPORT will step through the beam line, element by element, calculating the properties of the beam or other quantities, described below, where requested. Therefore one of the first elements is a specification of the phase space region occupied by the beam entering the system. Magnets and intervening spaces and other elements then follow in the sequence in which they occur in the beam line. Specifications of calculations to be done or of configurations other than normal are placed in the same sequence, at the point where their effect is to be made

    The growth of technology based on internet protocol has affected on the informatics and automatic controls of medical fields. The aim of this study was to establish the telemedical educational system by developing the high quality image transfer using the DVTS (digital video transmission system) on the high-speed internet network. Using telemedicine, we were able to send surgical images not only to domestic areas but also to international area. Moreover, we could discuss the condition of surgical procedures in the operation room and seminar room. The Korean-Japan cable network (KJCN) was structured in the submarine between Busan and Fukuoka. On the other hand, the Korea advanced research network (KOREN) was used to connect between Busan and Seoul. To link the image between the Hanyang University Hospital in Seoul and Kyushu University Hospital in Japan, we started teleconference system and recorded image-streaming system with DVTS on the circumstance with IPv4 network. Two operative cases were transmitted successfully. We could keep enough bandwidth of 60 Mbps for two-line transmission. The quality of transmitted moving image had no frame loss with the rate 30 per second. The sound was also clear and the time delay was less than 0.3 sec. Our study has demonstrated the feasibility of domestic and international telemedicine. We have established an international medical network with high-quality video transmission over internet protocol. It is easy to perform, reliable, and also economical. Thus, it will be a promising tool in remote medicine for worldwide telemedical communication in the future.

  3. Economic model of pipeline transportation systems

    Banks, W. F.

    1977-07-29

    The objective of the work reported here was to develop a model which could be used to assess the economic effects of energy-conservative technological innovations upon the pipeline industry. The model is a dynamic simulator which accepts inputs of two classes: the physical description (design parameters, fluid properties, and financial structures) of the system to be studied, and the postulated market (throughput and price) projection. The model consists of time-independent submodels: the fluidics model which simulates the physical behavior of the system, and the financial model which operates upon the output of the fluidics model to calculate the economics outputs. Any of a number of existing fluidics models can be used in addition to that developed as a part of this study. The financial model, known as the Systems, Science and Software (S/sup 3/) Financial Projection Model, contains user options whereby pipeline-peculiar characteristics can be removed and/or modified, so that the model can be applied to virtually any kind of business enterprise. The several dozen outputs are of two classes: the energetics and the economics. The energetics outputs of primary interest are the energy intensity, also called unit energy consumption, and the total energy consumed. The primary economics outputs are the long-run average cost, profit, cash flow, and return on investment.

  4. Engineering intracellular active transport systems as in vivo biomolecular tools.

    2006-11-01

    Active transport systems provide essential functions in terms of cell physiology and metastasis. These systems, however, are also co-opted by invading viruses, enabling directed transport of the virus to and from the cell's nucleus (i.e., the site of virus replication). Based on this concept, fundamentally new approaches for interrogating and manipulating the inner workings of living cells may be achievable by co-opting Nature's active transport systems as an in vivo biomolecular tool. The overall goal of this project was to investigate the ability to engineer kinesin-based transport systems for in vivo applications, specifically the collection of effector proteins (e.g., transcriptional regulators) within single cells. In the first part of this project, a chimeric fusion protein consisting of kinesin and a single chain variable fragment (scFv) of an antibody was successfully produced through a recombinant expression system. The kinesin-scFv retained both catalytic and antigenic functionality, enabling selective capture and transport of target antigens. The incorporation of a rabbit IgG-specific scFv into the kinesin established a generalized system for functionalizing kinesin with a wide range of target-selective antibodies raised in rabbits. The second objective was to develop methods of isolating the intact microtubule network from live cells as a platform for evaluating kinesin-based transport within the cytoskeletal architecture of a cell. Successful isolation of intact microtubule networks from two distinct cell types was demonstrated using glutaraldehyde and methanol fixation methods. This work provides a platform for inferring the ability of kinesin-scFv to function in vivo, and may also serve as a three-dimensional scaffold for evaluating and exploiting kinesin-based transport for nanotechnological applications. Overall, the technology developed in this project represents a first-step in engineering active transport system for in vivo

    1995-01-01

    Over 15 years ago, Oak Ridge National Laboratory (ORNL) developed two transportation routing models: HIGHWAY, which predicts truck transportation routes, and INTERLINE, which predicts rail transportation routes. Subsequent modifications have been made to enhance each of these models. Some of these changes include population density information for routes, HM-164 routing regulations for highway route controlled quantities of radioactive materials (RAM) truck shipments, and inclusion of waterway routing into INTERLINE. The AIRPORT model, developed 2 years after the HIGHWAY and INTERLINE models, serves as an emergency response tool. This model identifies the nearest airports from a designated location. Currently, the AIRPORT model is inactive. The Transportation Management Division of the US Department of Energy held a Baseline Requirements Assessment Session on the HIGHWAY, INTERLINE, and AIRPORT models in April 1994 to bring together many users of these models and other experts in the transportation routing field to discuss these models and to decide on the capabilities that needed to be added. Of the many needs discussed, the primary one was to have the network databases within a geographic information system (GIS). As a result of the Baseline Requirements Session, the development of a new GIS model has been initiated. This paper will discuss the development of the new Transportation Routing Analysis GIS (TRAGIS) model at ORNL

    Telemonitoring during the golden hour of patient transportation helps to improve medical care. Presently there are different physiological data acquisition and transmission systems using cellular network and radio communication links. Location monitoring systems and video transmission systems are also commercially available. The emergency patient transportation systems uniquely require transmission of data pertaining to the patient, vehicle, time of the call, physiological signals (like ECG, blood pressure, a body temperature, and blood oxygen saturation), location information, a snap shot of the patient, and voice. These requirements are presently met by using separate communication systems for voice, physiological data, and location that result in a lot of inconvenience to the technicians, maintenance related issues, in addition to being expensive. This paper presents design, development, and implementation of such a telemonitoring system for emergency patient transportation employing ARM 9 processor module. This system is found to be very useful for the emergency patient transportation being undertaken by organizations like the Emergency Management Research Institute (EMRI). PMID:27019844

    Full Text Available Adverse reactions are the main cause of treatment discontinuation among HIV+ individuals. Genes related to drug absorption, distribution, metabolism and excretion (ADME influence drug bioavailability and treatment response. We have investigated the association between single nucleotide polymorphisms (SNPs in 29 ADME genes and intolerance to therapy in a case-control study including 764 individuals. Results showed that 15 SNPs were associated with intolerance to nucleoside and 11 to non-nucleoside reverse transcriptase inhibitors (NRTIs and NNRTIs, and 8 to protease inhibitors (PIs containing regimens under alpha = 0.05. After Bonferroni adjustment, two associations remained statistically significant. SNP rs2712816, at SLCO2B1 was associated to intolerance to NRTIs (ORGA/AA = 2.37; p = 0.0001, while rs4148396, at ABCC2, conferred risk of intolerance to PIs containing regimens (ORCT/TT = 2.64; p = 0.00009. Accordingly, haplotypes carrying rs2712816A and rs4148396T alleles were also associated to risk of intolerance to NRTIs and PIs, respectively. Our data reinforce the role of drug transporters in response to HIV therapy and may contribute to a future development of personalized therapies.

  9. Decentralized control of multi-agent aerial transportation system

    2017-04-01

    Autonomous aerial transportation has multiple potential applications including emergency cases and rescue missions where ground intervention may be difficult. In this context, the following work will address the control of multi-agent Vertical Take-off and Landing aircraft (VTOL) transportation system. We develop a decentralized method. The advantage of such a solution is that it can provide better maneuverability and lifting capabilities compared to existing systems. First, we consider a cooperative group of VTOLs transporting one payload. The main idea is that each agent perceive the interaction with other agents as a disturbance while assuming a negotiated motion model and imposing certain magnitude bounds on each agent. The theoretical model will be then validated using a numerical simulation illustrating the interesting features of the presented control method. Results show that under specified disturbances, the algorithm is able to guarantee the tracking with a minimal error. We describe a toolbox that has been developed for this purpose. Then, a system of multiple VTOLs lifting payloads will be studied. The algorithm assures that the VTOLs are coordinated with minimal communication. Additionally, a novel gripper design for ferrous objects is presented that enables the transportation of ferrous objects without a cable. Finally, we discuss potential connections to human in the loop transportation systems.

    This document discusses the functions that are required to accept the waste, transport the waste, and provide the mandatory support activities. These functions are independent of any organizational structure and reflect a conventional and generally accepted transportation system involving casks; ancillary equipment; truck, rail, and barge transporters; cask and vehicle maintenance facilities; traffic management activities; and other related support system subelements. Where appropriate, the functions are ordered to identify their relationship with each other. This relationship is depicted graphically in functional flow block diagrams (FFBDs). The FFBDs provide a definition of the functions that the systems must perform; a tool to aid in the identification of important issues and trade-off studies; an important method for tracing requirements and decisions back to essential functions; and a basis for allocating the functions, a process that will identify where, how, and by whom they will be performed. 22 refs., 13 figs.

    The bundling of freight flows from multiple shippers into a synchromodal network is the key to a competitive and sustainable European transport system. Synchromodal means that by 1 or more chain management centers for a larger group of companies it is determined which modality is the most appropriate at any time for any goods in the networking infrastructure: road transport, rail transport or transport over waterways? The main question in this study was: What practical actions are required from governments and businesses in the Netherlands to realize both growth and sustainability of freight transport in the coming years through a synchromodal transportation system? This annex comprises an analysis of the environment, a survey of the policies, example of synchromodality cases, a SWOT-analysis, and elaborated conditions for synchromodality.

    Full Text Available The aim of this study was to examine the procedures of primary dental health care performed by oral health teams (OHTs adhering to the second cycle of the ‘National Programme for Improving Access and Quality of Primary Care’ (PMAQ-AB in Brazil. A cross-sectional descriptive analysis was performed, across 23 dental procedures comprising preventive, restorative/prosthetic, surgical, endodontic and oral cancer monitoring. Descriptive analysis shows that most of the oral health teams carry out basic dental procedures. However, most of the time, they do not keep adequate records of suspected cases of oral cancer, diagnosis tests or follow-ups, and do not perform dental prosthetic procedures. Data also showed disparities in the average number of procedures performed in each Brazilian geographical region in 2013–2014, ranging from 13.9 in the northern to 16.5 in the southern and south-eastern regions, reinforcing the great social disparities between them. Brazilian regions with the highest volume of dental need deliver the lowest number of dental procedures. The need to tackle inequalities and further shape the supply of appropriate primary health care (PHC is evident.

    To assess the distribution rate of legal suits according to drug (manufacturer), prescribing physician, and attorney filing the lawsuit. A descriptive study was carried out to assess the lawsuits in the São Paulo State (Southeastern Brazil) courts registry in 2006, and amounts spent in complying with these lawsuits, and total costs with medication thus resulting. In 2006, the São Paulo State Administration spent 65 million Brazilian reais in compliance with court decisions to provide medication to approximately 3,600 individuals. The total cost of the medication was 1.2 billion Brazilian reais. In the period studied, 2,927 lawsuits were examined. These lawsuits were filed by 565 legal professionals, among which 549 were attorneys engaged by private individuals (97.17% of the total legal professionals). The drugs scope of the lawsuits had been prescribed by 878 different physicians. By assessing the number of lawsuits filed per attorney, it was found that 35% of them were brought before the courts by 1% of them. The data related to the lawsuits and to the medication classified according to manufacturer, show that a small number of attorneys is responsible for the largest number of lawsuits filed to obtain these drugs. The finding that more than 70% of the lawsuits filed for certain drugs are the responsibility of one single attorney, may suggest a close connection between this professional and the manufacturer.

    Full Text Available This study presents an evaluation of metals and As deposition in the Bertioga Channel (Santos Region, Southeastern Brazilian coast along the last 150 years, which corresponds to the main anthropogenic activity in the area. The studied area is located in the so-called Baixada Santista, where the main Brazilian harbor and one of the most important industrial centers of the country are located. This work consisted of sampling five sediment cores along this channel. The cores were sliced every 2 cm, and the samples were analyzed by ICP-OES to determine the levels of heavy metals (Cd, Cr, Cu, Ni, Pb and Zn and As. The enrichment factors (EF were calculated to identify the relative heavy-metal toxicity of the sediments and the anthropogenic contribution of the investigated elements. EFs indicated the absence of contamination for the heavy metals but a higher input of As in two cores (B2 and B5. According to the age models of the cores, this enrichment corresponds to the end of the 19th century, when Santos harbor was inaugurated, and to the 1970s, when Santos harbor activities expanded.

    The integrated Management System of BNFL Transport and Pacific Nuclear Transport Limited (PNTL) is subject to continuous improvement by the application of established improvement techniques adopted by BNFL. The technique currently being used is the application of a Total Quality Management (TQM) philosophy, involving the identification of key processes, benchmarking against existing measures, initiating various improvement projects and applying process changes within the Company. The measurement technique being used is based upon the European Foundation for Quality Management Model (EFQM). A major initiative was started in 1996 to include the requirements of the Environmental Management Systems standard ISO 14001 within the existing integrated management system. This resulted in additional activities added to the system, modification to some existing activities and additional training for personnel. The system was audited by a third party certification organisation, Lloyds Register Quality Assurance (LRQA), during 1997. This paper describes the arrangements to review and update the integrated management system of BNFL Transport and PNTL to include the requirements of the environmental standard ISO 14001 and it also discusses the continuous improvement process adopted by BNFL Transport.

    2018-02-01

    For "static memory materials" the bulk properties depend on boundary conditions. Such materials can be realized by classical statistical systems which admit no unique equilibrium state. We describe the propagation of information from the boundary to the bulk by classical wave functions. The dependence of wave functions on the location of hypersurfaces in the bulk is governed by a linear evolution equation that can be viewed as a generalized Schrödinger equation. Classical wave functions obey the superposition principle, with local probabilities realized as bilinears of wave functions. For static memory materials the evolution within a subsector is unitary, as characteristic for the time evolution in quantum mechanics. The space-dependence in static memory materials can be used as an analogue representation of the time evolution in quantum mechanics - such materials are "quantum simulators". For example, an asymmetric Ising model on a Euclidean two-dimensional lattice represents the time evolution of free relativistic fermions in two-dimensional Minkowski space.

    Full Text Available The main objective of Slovakia’s transport policy is to reduce the number of traffic accidents and increase safety on our roads. Implementation of intelligent transport systems presents one of the possibilities how to meet this goal. Acceptance of these systems by motor vehicle drivers and other road traffic participants is necessary in order for them to fulfill their purpose. Only if the drivers will accept intelligent transport systems, it is possible to flexibly and effectively manage road traffic flexibly and effectively. From the perspective of a driver it concerns, in particular, the possibility of using alternative routes when traffic accidents or other obstacles occurs on the route that would significantly affect the continuity and safety of road traffic. Thanks to these technologies, it is possible to choose the appropriate route while driving, of course based on the criterion, which the driver considers the most important during the transport from origin to destination (driving time, distance from origin to destination, fuel consumption, quality of infrastructure. Information isare provided to the driver through variable message signs or directly in the vehicle (RDS-TMC. Another advantage of intelligent transport systems is a positive impact on psychological well-being of the driver while driving. Additional information about the possible obstacles, weather conditions and dangerous situations that occur on the roads as well as alternative routes are provided to the driver well in advance. This paper is mainly focused on how the drivers perceive the influence of intelligent transport systems in Žilina region.

  15. Waste Information Management System with Integrated Transportation Forecast Data

    International Nuclear Information System (INIS)

    Upadhyay, H.; Quintero, W.; Shoffner, P.; Lagos, L.

    2009-01-01

    The Waste Information Management System with Integrated Transportation Forecast Data was developed to support the Department of Energy (DOE) mandated accelerated cleanup program. The schedule compression required close coordination and a comprehensive review and prioritization of the barriers that impeded treatment and disposition of the waste streams at each site. Many issues related to site waste treatment and disposal were potential critical path issues under the accelerated schedules. In order to facilitate accelerated cleanup initiatives, waste managers at DOE field sites and at DOE Headquarters in Washington, D.C., needed timely waste forecast and transportation information regarding the volumes and types of waste that would be generated by the DOE sites over the next 40 years. Each local DOE site has historically collected, organized, and displayed site waste forecast information in separate and unique systems. However, waste and shipment information from all sites needed a common application to allow interested parties to understand and view the complete complex-wide picture. The Waste Information Management System with Integrated Transportation Forecast Data allows identification of total forecasted waste volumes, material classes, disposition sites, choke points, technological or regulatory barriers to treatment and disposal, along with forecasted waste transportation information by rail, truck and inter-modal shipments. The Applied Research Center (ARC) at Florida International University (FIU) in Miami, Florida, has deployed the web-based forecast and transportation system and is responsible for updating the waste forecast and transportation data on a regular basis to ensure the long-term viability and value of this system.

    Garabedian, Harold T.

    2008-03-30

    A great deal of research funding is being devoted to the use of hydrogen for transportation fuel, particularly in the development of fuel cell vehicles. When this research bears fruit in the form of consumer-ready vehicles, will the fueling infrastructure be ready? Will the required fueling systems work in cold climates as well as they do in warm areas? Will we be sure that production of hydrogen as the energy carrier of choice for our transit system is the most energy efficient and environmentally friendly option? Will consumers understand this fuel and how to handle it? Those are questions addressed by the EVermont Wind to Wheels Hydrogen Project: Sustainable Transportation. The hydrogen fueling infrastructure consists of three primary subcomponents: a hydrogen generator (electrolyzer), a compression and storage system, and a dispenser. The generated fuel is then used to provide transportation as a motor fuel. EVermont Inc., started in 1993 by then governor Howard Dean, is a public-private partnership of entities interested in documenting and advancing the performance of advanced technology vehicles that are sustainable and less burdensome on the environment, especially in areas of cold climates, hilly terrain and with rural settlement patterns. EVermont has developed a demonstration wind powered hydrogen fuel producing filling system that uses electrolysis, compression to 5000 psi and a hydrogen burning vehicle that functions reliably in cold climates. And that fuel is then used to meet transportation needs in a hybrid electric vehicle whose internal combustion engine has been converted to operate on hydrogen Sponsored by the DOE EERE Hydrogen, Fuel Cells & Infrastructure Technologies (HFC&IT) Program, the purpose of the project is to test the viability of sustainably produced hydrogen for use as a transportation fuel in a cold climate with hilly terrain and rural settlement patterns. Specifically, the project addresses the challenge of building a renewable

    1985-02-01

    The Cascade ICF reactor features a flowing blanket of solid BeO and LiAlO 2 granules with very high temperature capability (up to approx. 2300 K). The authors present here the design of a high temperature granule transport and heat exchange system, and two options for high efficiency power conversion. The centrifugal-throw transport system uses the peripheral speed imparted to the granules by the rotating chamber to effect granule transport and requires no additional equipment. The heat exchanger design is a vacuum heat transfer concept utilizing gravity-induced flow of the granules over ceramic heat exchange surfaces. A reference Brayton power cycle is presented which achieves 55% net efficiency with 1300 K peak helium temperature. A modified Field steam cycle (a hybrid Rankine/Brayton cycle) is presented as an alternate which achieves 56% net efficiency

    Radio-Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. In Korea, Low-to-Intermediate Level Radioactive Wastes (LILW) are planed to be disposed at Kyeonju disposal repository, and 100,000 LILW drums will be disposed for the first 10 years of disposal. Tracking of these LILW drums is one of the important parts for safe transportation. To track the LILW drums during the transport as well as storage and disposal, RFID can be the prospective method for tracking the LILW drums. In this report, RFID system is introduced to the LILW transport from the generation site to disposal site, and one possible RFID system is suggested as a preliminary study

    Several studies suggest that the vitamin B12 (B12) transport system can be used for the cellular delivery of B12-conjugated drugs, also in long-term treatment Whether this strategy will affect the endogenous metabolism of B12 is not known. To study the effect of treatment with excess B12...... levels for methylenetetrahydrofolate reductase in kidneys and for transcobalamin and transcobalamin receptor in the salivary glands were reduced. Our study confirms the feasibility of delivering drugs through the B12 transport system but emphasises that B12 status should be monitored because...... there is a risk of decreasing the transport of endogenous B12. This risk may lead to B12 deficiency during prolonged treatment....

    Casearia sylvestris S.w (Salicaceae) is catalogued by the Brazilian Unified Health System as a plant of interest for the Brazilian population with the purpose of treating inflammatory disorders, such as pain and gastrointestinal disorders based on the folk use and some literature about efficacy; however, no toxicological studies concerned the safety of extract fluid of this plant have been reported. The present study was carried out to evaluate the acute and subchronic toxicity of the hydroethanolic extract fluid (FE) obtained from leaves of C. sylvestris in Wistar rats. In the acute toxicity test three female Wistar rats were treated with a single dose of FE (2000 mg/kg) administered by oral gavage and observed for 14 days in order to identify signs of toxicity or death. In subchronic toxicity study animals received, by daily gavage three doses 60, 120 and 240 mg/kg of the FE of the plant for 28 and 90 days. The animals were observed daily for clinical signs and mortality. Body weight and food consumption were measured weekly and at the end of treatment were analysed hematological, biochemical and histopathological parameters. Also was analysed the cellularity of bone marrow and spleen. Moreover, phytochemical analysis by HPLC-PDA-ESI(+)/MS and CG/MS/EI was carried out to qualify the constituents of the extract. The results of acute study indicated that the LD50 is higher than 2000 mg/kg and at 28 and 90 day oral toxicity showed that there were no toxic effects detected in any of the parameters evaluated: body weight and relative organ weight, general behavioral changes, haematological and biochemical parameters and histopathological examination. The analysis by HPLC-PDA-ESI(+)/MS and CG/MS/EI identified the flavonoids rutin, quercetin and luteolin and also chlorogenic on the extract. Based on this study the hydroethanolic fluid extract of C. sylvestris could be safe even when used over a long period for therapeutic uses proposed by the Brazilian Unified Health

    The crisis of the Brazilian Penitentiary System is visible with overcrowding, the appearance and growth of criminal factions, the lack of infrastructure of prisons, etc. This scenario led to the adoption of new technologies, such as the body inspection by X-rays, known as Body scanners. The technology is capable of detecting various illicit objects hidden under clothes or even in the pockets of individuals searched, following the recommendation of the National Council of Criminal and Penitentiary Policy, allowing a more effective search and the extinction of the intimate searches. The objective of this study is to evaluate the social impacts of the use of body inspection technology in prison units, including aspects of radiological protection related to operation and maintenance

    ABSTRACT We estimated the costs of a molecular test for Mycobacterium tuberculosis and resistance to rifampin (Xpert MTB/RIF) and of smear microscopy, within the Brazilian Sistema Único de Saúde (SUS, Unified Health Care System). In SUS laboratories in the cities of Rio de Janeiro and Manaus, we performed activity-based costing and micro-costing. The mean unit costs for Xpert MTB/RIF and smear microscopy were R$35.57 and R$14.16, respectively. The major cost drivers for Xpert MTB/RIF and smear microscopy were consumables/reagents and staff, respectively. These results might facilitate future cost-effectiveness studies and inform the decision-making process regarding the expansion of Xpert MTB/RIF use in Brazil. PMID:26785963

    We review recent results on the anomalous transport in one-dimensional and quasi-one-dimensional systems with bulk and surface disorder. Principal attention is paid to the role of long-range correlations in random potentials for the bulk scattering and in corrugated profiles for the surface scattering. It is shown that with the proper type of correlations one can construct such a disorder that results in a selective transport with given properties. Of particular interest is the possibility to arrange windows of a complete transparency (or reflection) with dependence on the wave number of incoming classical waves or electrons

    A semi-analytical technique for the charged particle transport in one-dimensional finite media is developed which can be applied to multi-energy multi-region systems with arbitrary degree of anisotropy in scattering. For this purpose the transport equation is cast in the form of coupled integral equations separating spatial and energy-angle transmission. The spatial transmission is evaluated using discrete ordinate representation in space, energy and direction cosine for the particle source and flux. The collision integral is evaluated using discrete ordinate representation in energy and legendre polynomial approximation in the direction cosine. A computer code based on the above formulation is described

    The objective of this paper is to describe the main characteristics of the Nuclear Regulatory Authority (Autoridad Regulatoria Nuclear - ARN) management system applied to the transport of radioactive material, in Argentina. In the frame of ARN's quality policy, 'Protection against ionizing radiation on transport of radioactive materials' was selected as one of the regulatory processes, named TMR from now on. ARN's management system is integrally based on ISO 9000 system addressed to help organizations in designing and implementing their quality management systems. TMR process was split into five sub processes in order to facilitate the implementation of the system. Such sub processes were defined taking into account of the main functions developed by ARN in the branch of safe transport of radioactive materials. For each of this processes were specified their objectives, inputs, activities and outputs, clients and stakeholders, responsibilities, supporting documents, control of documents and records, control of non-conformances, monitoring and measurements, audits, feedback and improvement. Supporting documents for sub processes were issued, validated, reviewed and improved as an essential point to achieve continuous improving. Simultaneously, some indexes were defined to monitor and measures sub processes as a way to show objective evidence of conformity with objectives. Finally, as conclusions of this paper, they will be showed the main obstacles and troubleshooting found in the design and implementation of management system as well as their solutions and state of advance.

    1990-01-01

    As utilities with nuclear power plants face increasing near term spent fuel store needs, various systems for dry storage such as the NUTECH Horizontal Modular Storage (NUHOMS) system are being implemented to augment existing spent fuel pool storage capacities. These decisions are based on a number of generic and utility specific considerations including both short term and long term economics. Since the US Department of Energy (DOE) is tasked by the Nuclear Waste Policy Act with the future responsibility of transporting spent fuel from commercial nuclear power plants to a Monitored Retrievable Storage (MRS) facility anchor a permanent geologic repository, the interfaces between the utilities at-reactor dry storage system and the DOE's away-from-reactor transportation system become important. This paper presents a study of the interfaces between the current at-reactor NUHOMS system and the future away-from-reactor DOE transportation system being developed under the Office of Civilian Radioactive Waste Management (OCRWM) program. 7 refs., 9 figs., 1 tab

    Berle, Oyvind; Asbjornslett, Bjorn Egil; Rice, James B.

    2011-01-01

    World trade increasingly relies on longer, larger and more complex supply chains, where maritime transportation is a vital backbone of such operations. Long and complex supply chain systems are more prone to being vulnerable, though through reviews, no specific methods have been found to assess vulnerabilities of a maritime transportation system. Most existing supply chain risk assessment frameworks require risks to be foreseen to be mitigated, rather than giving transportation systems the ability to cope with unforeseen threats and hazards. In assessing cost-efficiency, societal vulnerability versus industrial cost of measures should be included. This conceptual paper presents a structured Formal Vulnerability Assessment (FVA) methodology, seeking to transfer the safety-oriented Formal Safety Assessment (FSA) framework into the domain of maritime supply chain vulnerability. To do so, the following two alterations are made: (1) The focus of the assessment is defined to ensure the ability of the transportation to serve as a throughput mechanism of goods, and to survive and recover from disruptive events. (2) To cope with low-frequency high-impact disruptive scenarios that were not necessarily foreseen, two parallel tracks of risk assessments need to be pursued-the cause-focused risk assessment as in the FSA, and a consequence-focused failure mode approach.

    2018-01-01

    The study of the mechanism of β-N-methylamino-L-alanine (BMAA) neurotoxicity originally focused on its effects at the N-methyl-D-aspartate (NMDA) receptor. In recent years, it has become clear that its mechanism of action is more complicated. First, there are certain cell types, such as motor neurons and cholinergic neurons, where the dominate mechanism of toxicity is through action at AMPA receptors. Second, even in cortical neurons where the primary mechanism of toxicity appears to be activation of NMDA receptors, there are other mechanisms involved. We found that along with NMDA receptors, activation of mGLuR5 receptors and effects on the cystine/glutamate antiporter (system x c -) were involved in the toxicity. The effects on system x c - are of particular interest. System x c - mediates the transport of cystine into the cell in exchange for releasing glutamate into the extracellular fluid. By releasing glutamate, system x c - can potentially cause excitotoxicity. However, through providing cystine to the cell, it regulates the levels of cellular glutathione (GSH), the main endogenous intracellular antioxidant, and in this way may protect cells against oxidative stress. We have previously published that BMAA inhibits cystine uptake leading to GSH depletion and had indirect evidence that BMAA is transported into the cells by system x c -. We now present direct evidence that BMAA is transported into both astrocytes and neurons through system x c -. The fact that BMAA is transported by system x c - also provides a mechanism for BMAA to enter brain cells potentially leading to misincorporation into proteins and protein misfolding.

    Full Text Available Railway transport is one of the system-forming sectors of the economy, requiring huge financial investments. At the same time, the sphere of transport can become an instrument for overcoming the economic crisis and creating conditions for the growth of the national economy, as investing in the transport industry contributes to the development of related industries and the provision of jobs. The development of transport infrastructure to meet the needs of the economy and the implementation of transit potential is a strategic direction outlined in the Strategic Plan of the Ministry of Investment and Development of the Republic of Kazakhstan for 2014–2018. The task of Kazakhstan is to ensure an increase in the transit freight traffic between the People's Republic of China and the European Union, which goes on a land route through the territory of the republic. So, according to the results of 2014, the volume of transit traffic amounted to 17.5 million tons, revenues from transit transportation amounted to 180 billion tenge. JSC "Astyk Trans" is currently one of the largest operators in the market of railway transportation of grain cargo in Kazakhstan, but slightly inferior to JSC "NC "KTZ" in domestic transportation of 42042 wagons to 45049, while for export shipments to the share of JSC "AstykTrans" there are 34787 carloads, which is 50.3% of transportation of JSC "NC "KTZ ". In order to increase the efficiency of transport and logistics services, reduce the distance and time of delivery between the busiest sections of the railway, construction projects for transport and logistics centers and the formation of an internal terminal network are planned in the industry. By 2020, the railway industry plans to build 1400 km of new railway lines to accelerate the delivery of goods and passengers within the country and beyond Kazakhstan, with at least 50% of the financing of construction to be carried out through private investment.

    With the arising of spent fuel from nuclear power plants, a national policy of a closed nuclear fuel cycle has been determined. Following being stored at reactor sites for at least 5 years (with storage maximum of 10 years), spent fuel will be transferred into an away-from-reactor wet centralized storage facility, waiting for reprocessing. Therefore, China's spent fuel management activities would be involved in at-reactor storage, transportation, away-from-reactor storage and reprocessing, as well as certainly radioactive waste management. The status of the nuclear fuel cycle will be briefly discussed and the potential spent fuel transportation system in China is discussed in detail, covering administration, flask, terminals and transportation by sea, rail and road.

    Xiao, Cong; Li, Dingping; Ma, Zhongshui; Niu, Qian

    Thermoelectric transport in strongly spin-orbit coupled two-dimensional Rashba systems is studied using the analytical solution of the linearized Boltzmann equation. To highlight the effects of inter-band scattering, we assume point-like potential impurities, and obtain the band-and energy-dependent transport relaxation times. Unconventional transport behaviors arise when the Fermi level lies near or below the band crossing point (BCP), such as the non-Drude electrical conducivity below the BCP, the failure of the standard Mott relation linking the Peltier coefficient to the electrical conductivity near the BCP, the enhancement of diffusion thermopower and figure of merit below the BCP, the zero-field Hall coefficient which is not inversely proportional to and not a monotonic function of the carrier density, the enhanced Nernst coefficient below the BCP, and the enhanced current-induced spin-polarization efficiency.

    We have undertaken the inventory and assembly of the ATP binding cassette (ABC) transporter systems in the complete genome of Bacillus subtilis. We combined the identification of the three protein partners that compose an ABC transporter (nucleotide-binding domain, NBD; membrane spanning domain, MSD; and solute-binding protein, SBP) with constraints on the genetic organization. This strategy allowed the identification of 86 NBDs in 78 proteins, 103 MSD proteins and 37 SBPs. The analysis of transcriptional units allows the reconstruction of 59 ABC transporters, which include at least one NBD and one MSD. A particular class of five dimeric ATPases was not associated to MSD partners and is assumed to be involved either in macrolide resistance or regulation of translation elongation. In addition, we have detected five genes encoding ATPases without any gene coding for MSD protein in their neighborhood and 11 operons that encode only the membrane and solute-binding proteins. On the bases of similarities, three ATP-binding proteins are proposed to energize ten incomplete systems, suggesting that one ATPase may be recruited by more than one transporter. Finally, we estimate that the B. subtilis genome encodes for at least 78 ABC transporters that have been split in 38 importers and 40 extruders. The ABC systems have been further classified into 11 sub-families according to the tree obtained from the NBDs and the clustering of the MSDs and the SBPs. Comparisons with Escherichia coli show that the extruders are over-represented in B. subtilis, corresponding to an expansion of the sub-families of antibiotic and drug resistance systems.

    European freight transport emissions and fuel consumption are projected to increase. This study focuses on long distance freight transport (LDFT) and explores possible sustainable futures through quantitative modeling. The evaluation was part of European foresight process between researchers, policy makers and freight companies (FREIGHTVISION). Greenhouse gas (GHG) emissions and energy demand of road, rail and inland waterways were estimated for an EU-27 in 2005. Development was extrapolated to 2050 based on technology and freight performance forecasts. Stakeholders found the forecasted GHG emissions and fossil fuel share unsustainable, so alternative futures were developed with backcasting. The developed emission model was run with random parameter combinations to screen a set of sustainable futures, with an 80% reduction of GHG emissions and fossil fuel share. Freight transport performance was not controlled in the backcasts, but several sustainable futures were found if significant changes in transport efficiency and energy mix are implemented. In spite of agreeing on the importance of reducing emissions, stakeholders had difficulties in choosing a preferred technological future. Simple models were found to be an effective tool for communicating the influence of various measures. Further research is recommended to screen preferable technological roadmaps from the broad range of available futures. - Research highlights: → Sustainable transport systems were explored with modeling and stakeholder workshops. → Backcasting identified technological options for reducing greenhouse gas emissions by 80%. → Improving road vehicle efficiency, engine efficiency and fuel mix showed the greatest potential.

    This book concerns the most up-to-date advances in computational transport phenomena (CTP), an emerging tool for the design of gas-solid processes such as fluidized bed systems. The authors examine recent work in kinetic theory and CTP and illustrate gas-solid processes’ many applications in the energy, chemical, pharmaceutical, and food industries. They also discuss the kinetic theory approach in developing constitutive equations for gas-solid flow systems and how it has advanced over the last decade as well as the possibility of obtaining innovative designs for multiphase reactors, such as those needed to capture CO2 from flue gases. Suitable as a concise reference and a textbook supplement for graduate courses, Computational Transport Phenomena of Gas-Solid Systems is ideal for practitioners in industries involved with the design and operation of processes based on fluid/particle mixtures, such as the energy, chemicals, pharmaceuticals, and food processing.

    What is common between a motor protein, an ant and a vehicle? Each can be modelled as a"self-propelled particle"whose forward movement can be hindered by another in front of it. Traffic flow of such interacting driven"particles"has become an active area of interdisciplinary research involving physics, civil engineering and computer science. We present a unified pedagogical introduction to the analytical and computational methods which are currently used for studying such complex systems far from equilibrium. We also review a number of applications ranging from intra-cellular molecular motor transport in living systems to ant trails and vehicular traffic. Researchers working on complex systems, in general, and on classical stochastic transport, in particular, will find the pedagogical style, scholarly critical overview and extensive list of references extremely useful.

    There are three troublesome institutional concerns which face every large-quantity radioactive materials shipment - routing, pre-notification, and emergency response. People want to know: where's the shipment going and how's it getting there? States want to know what's being shipped and when? What kind of response to accidents is needed for this shipment and who'll respond? DOE is developing a transportation tracking system, based on a rapidly developing technology to determine geographical location using geo-positioning satellite systems. This technology will be used to track unclassified radioactive materials shipments in real-time. It puts those charged with monitoring transportation status on top of every shipment. Besides its practical benefits in the areas of logistics planning and execution, it demonstrates emergency preparedness has indeed been considered and close monitoring is possible. This paper will describe the system's technical detail, DOE plans and policy for its implementation, and the state of satellite positioning technology

  20. Modular transportation system with a three dimensional routeing

    Full Text Available In intra-enterprise logistics and automation of manufacturing processes general a rising productivity by high flexibility is required. Existing transportation systems exclusively use two-dimensional track sections, because they can be served with standard drives. Because of these simple structures the transport speed is limited and thereby also the throughput. In this paper now a modular transportation system is presented which could reach higher speeds with a direct drive and the use of centrifugal force compensating curves. Simultaneously the system also can change the altitude. All this succeeds with the integration of three-dimensional track sections. Therefore a two piped guiding system with a long stator linear motor was designed. To combine the linear motor with the three dimensional track special stator elements were developed which allow a bending of the stator to follow the route course. The current work deals with the implementation of a mechanical passive switch, which is operated by the electromagnetic forces of the linear motor. So no additional mechanical actors or a separate electromagnetic system are necessary.
