    The primary goal of the workshop was to share experiences of sustainable transport practices from invited medium-sized cities in Latin America and Asia. The purpose was to learn how sustainable mechanisms have been incorporated into national planning and implementation systems. Emphasis was given to understand what concrete mechanism work to promote sustainable transport in the selected projects. The workshop included participation of transport economics and engineers, policy makers and policy-advisors, and key representatives from the transportation government and non-governmental sector in El Salvador. Among participants there were also members from academia, private consultants and international NGOs. The workshop provided a basis for outreach in terms of directly informing participants on the specific experiences brought in by the participating countries. The Workshop set out to address the following main objectives: To demonstrate successful examples of transportation initiatives that show positive sustainable economic, environmental and social benefits in selected developing countries; To provide a forum for discussion of sustainable transport paths; To develop a network for information exchange and capacity building; To gather information on concrete mechanisms to promote sustainable transportation; To demonstrate efficient mechanisms and tools for collection and analysis of data in transport; To create an inventory of success stories and alternative visions for the future. Several institutions collaborated in organising the event: the Intermediate Technology Development Group (ITDG-Sri Lanka), The Peace and Development Research Group from Goeteborg University and institutions within El Salvador: Centro Salvadeoreno de Tecnologia Apropiada (CESTA), and the Climate Change Communication office of the Ministry of Environment in Salvador.

    Full Text Available The main issues in Jabodetabek concerning the management of transportation are related to the increased use of private vehicles and the decreased use of public transportation, overcrowding daily traffic in Jabodetabek, the high congestion followed by insecurity in traffic, environmental pollution, uncontrolled growth of and underdeveloped infrastructure, and irregularities in land use. To overcome these problems, sustainable transportation management becomes very important in which the government should be able to cope with environmental, economic and social factors under the decision making related to transportation in Jabodetabek. Therefore, through interactive planning, this study will examine intergovernmental cooperation initiatives on sustainable transportation management in Jabodetabek. This study uses qualitative and descriptive method through literature study and existing statistics as the resources to apply the interactive planning approach. The result shows that there are found a number of problems and gaps in the management of transportation in Jabodetabek that needs to be reduced because it has the same scope of other gaps. From these problems can be made further action programs and policies in accordance with the resources owned, and then, the design of implementation made and controlled whether in accordance with the purpose or not. Thus, sustainable transportation management in the Jabodetabek needs to be done jointly in an institutional or policyframework involving governments Jabodetabekpunjur, BKSP Jabodetabekpunjur, and the private sector.

    Full Text Available This paper is concerned with building a sustainable policy framework for transport development in Nigeria. Its objective is to review the country’s transport policy initiatives in order to understand the extent to which it addresses Nigeria’s mobility and transportation problems. From published materials and official government documents and files, the study identifies four national policy initiatives which are reviewed and analysed with regard to their context, contents, and consequences. The study reveals that while the policy initiatives could be said to be adequate and comprehensive in terms of their context and contents, the major challenge is implementation of recommended solutions. The study therefore provides a general checklist to guide policy direction, while advocating for policy-based researches and empirical studies in order to provide the data base for formulation of a sustainable national transport policy for Nigeria.

    Full Text Available Sustainable marketing is a holistic approach that puts equal emphasis on environmental, social equity, and economic concerns in the development of marketing strategies. The purpose of the study is to examine and discuss the sustainable agricultural marketing initiatives practiced throughout the World and Turkey, and to put forth suggestions to further improve the performance of agricultural marketing initiatives in Turkey. Some of the sustainable agricultural marketing initiatives practiced around the world are carried out through civil organizations. Furthermore; some of these initiatives have also launched by farmers, consumers, food processors and retailers. The long-term strategies to increase these initiatives should be determined due to the fact that examples of successful sustainable agricultural marketing initiatives are inadequate and cannot be spread in Turkey. In this context, first of all, the supports provided by the government to improve agricultural marketing systems, such as EU funds for rural development should be compatible with the goals of sustainable marketing. For this purpose, it should be examined whether all proposed projects related to agricultural marketing meet the social, economic, and environmental principles of sustainable marketing. It is important that supporting organizations, especially civil society organisations, should take an active role for faster dissemination and adoption of sustainable agricultural marketing practices in Turkey. These organizations may provide technical assistance in preparing successful project proposals and training to farm groups. In addition, the other organizations, such as local administrations, producers' associations, cooperatives, can contribute to the success of sustainable agricultural marketing initiatives. The use of direct marketing strategies and vertical integration attempts in sustainable agricultural marketing initiatives that will likely be implemented in Turkey is

  14. Resource-efficient intelligent transportation systems as a basis for sustainable development. Overview of initiatives and strategies

    Directory of Open Access Journals (Sweden)

    Yuriy Vovk

    2016-12-01

    Full Text Available Intelligent transportation systems mostly operate on information exchange principle between vehicles and roadside infrastructure. They are commonly regarded as a base technology for persistent diminution of road accidents and traffic efficiency increase. However, intelligent transportation systems can also be used at all levels of transportation systems as a basis for stable development of cities, enterprises, regions, states, continents. According to the research, the existing intelligent transportation systems not only provide the considerable reduction of greenhouse gases emissions, fuel saving, time of travel cutting, but they don’t marginalize citizens’ mobility as well. Thus, the further development and introduction of modern transportation innovative technologies will allow to guarantee the energy- and resources efficiency and, therefore, the sustainable development of the whole society.

    Full Text Available Environmental protection has become a common issue in every area, but extremely important for the domains which deal with intensive energy consumption as it is the case of the transportation. Achieving the sustainable cities on the other hand, is also focused on the protection of the environment in order to provide a higher quality of life for the population. Therefore it is considered that by improving the urban transportation planning additional benefits could be provided for both the environment and the sustainable development of the cities. One possibility is to supplement the traditionally land-use plans with the transportrelated zones analysis, where the city is divided in public transport, pedestrian and caroriented zones. Analyzing the transport-related zones of a city is important as it provides additional information in the assessment of the development trend. The process of zoning was conducted for the city of Cluj-Napoca, Romania. In this paper, the outcome of the zoning was analyzed for a more comprehensive review of the urban transport in order to attain a sustainable-oriented approach of the urban area development.

    This book aims to provide a good understanding of and perspective on sustainable transport in Asia by focusing on economic, environmental, and social sustainability. It is widely acknowledged that the current situation and trends in transport are not always sustainable in Asia, due in part to the fast-growing economy and the astounding speed of urbanization as well as least-mature governance. As essential research material, the book provides strong support for policy makers and planners by comprehensively covering three groups of strategies, characterized by the words “avoid” (e.g., urban form design and control of car ownership), “shift” (e.g., establishing comprehensive transportation systems and increasing public transportation systems for both intracity and intercity travel), and “improve” (e.g., redesign of paratransit system, low-emission vehicles, intelligent transportation systems, and eco-life). These are elaborated in the book alongside consideration of the uncertainty of policy effects ...

    Full Text Available Green highway initiative is the transportation corridors based on sustainable concept of roadway. It incorporates both transportation functionality and ecological requirements. Green highway also provides more sustainable construction technique that maximizes the lifespan of highway. Waste management is one of the sustainable criterias in the elements of green highway. Construction of highway consumes enormous amounts of waste in term of materials and energy. These wastes need to be reduce to sustain the environment. This paper aims to identify the types of waste produced from highway construction. Additionally, this study also determine the waste minimization strategy and waste management practiced.. This study main focus are construction and demolition waste only. The methodology process begin with data collection by using questionnaire survey. 22 concession companies listed under Lembaga Lebuhraya Malaysia acted as a respondent. The questionnaires were distributed to all technical department staffs. The data received was analyzed using IBM SPSS. The results shows the most production of waste is wood, soil, tree root and concrete. The least production of waste is metal. For waste minimization, the best waste minimization is reuse for all type of waste except for tree root and stump. Whereas, the best waste management is providing strategic plan. The least practice for waste management is recording the quantity of waste.

    More than a dozen energy experts convened in Houston, Texas, on February 13, 2009, for the first in a series of four regionally-based energy summits being held by the Council on Competitiveness. The Southern Energy Summit was hosted by Marathon Oil Corporation, and participants explored the public policy, business and technological challenges to increasing the diversity and sustainability of U.S. energy supplies. There was strong consensus that no single form of energy can satisfy the projected doubling, if not tripling, of demand by the year 2050 while also meeting pressing environmental challenges, including climate change. Innovative technology such as carbon capture and storage, new mitigation techniques and alternative forms of energy must all be brought to bear. However, unlike breakthroughs in information technology, advancing broad-based energy innovation requires an enormous scale that must be factored into any equation that represents an energy solution. Further, the time frame for developing alternative forms of energy is much longer than many believe and is not understood by the general public, whose support for sustainability is critical. Some panelists estimated that it will take more than 50 years to achieve the vision of an energy system that is locally tailored and has tremendous diversity in generation. A long-term commitment to energy sustainability may also require some game-changing strategies that calm volatile energy markets and avoid political cycles. Taking a page from U.S. economic history, one panelist suggested the creation of an independent Federal Energy Reserve Board not unlike the Federal Reserve. The board would be independent and influence national decisions on energy supply, technology, infrastructure and the nation's carbon footprint to better calm the volatile energy market. Public-private efforts are critical. Energy sustainability will require partnerships with the federal government, such as the U.S. Department of Energy

    Since the days of the Manhattan Project of World War II, the economic well being of the Tri-Cities (Pasco, Kennewick, and Richland) of Washington State has been tied to the US Department of Energy missions at the nearby Hanford Site. As missions at the Site changed, so did the economic vitality of the region. The Hanford Site is now poised to complete its final mission, that of environmental restoration. When restoration is completed, the Site may be closed and the effect on the local economy will be devastating if action is not taken now. To that end, economic diversification and transition are being planned. To facilitate the process, the Hanford Site will become a sustainable development demonstration project

    Metropolitan transportation and land development patterns in most of the world are growing increasingly unsustainable. Many factors point to the need for adoption of a new paradigm for sustainable transportation and community development in both high and low income countries: overpopulation, growing air pollution, limited physical and economic capacity to expand automobile-based transportation systems without community destruction, growing inequality in the distribution of resources, and the urgent need to limit global CO{sub 2} emissions to slow the place of global warming. This paper discusses the new paradigm for integrated and sustainable transport strategies. (author) 9 refs.

These tools address activities that significantly influence resource consumption, waste generation, and hazard generation including air pollution and greenhouse gases. In addition, the tools have been evaluated using four screening criteria: relevance to community decision making, tools in an appropriate developmental stage, tools that may be transferrable to situations useful for communities, and tools with requiring skill levels appropriate to communities. This document provides an initial gap analysis in the area of community sustainability decision support tools. It provides a reference to communities for existing decision support tools, and a set of gaps for those wishing to develop additional needed tools to help communities to achieve sustainability. It contributes to SHC 1.61.4

    The Boston Architectural College's Urban Sustainability initiative is a demonstration project as defined by the National Energy Technology Laboratory. BAC's proposed project with the U.S. Department of Energy - NETL, is a large part of that overall initiative. The BAC's Urban Sustainability Initiative is a multi-part project with several important goals and objectives that will have a significant impact on the surrounding neighborhood including: energy conservation, reduction of storm water runoff, generation of power through alternative energy sources, elimination/reduction of BAC carbon footprint, and to create a vehicle for ongoing public outreach and education. Education and outreach opportunities will serve to add to the already comprehensive Sustainability Design courses offered at BAC relative to energy savings, performance and conservation in building design. At the finish of these essential capital projects there will be technical materials created for the education of the design, sustainability, engineering, community development and historic preservation communities, to inform a new generation of environmentally-minded designers and practitioners, the city of Boston and the general public. The purpose of the initiative, through our green renovations program, is to develop our green alley projects and energy saving renovations to the BAC physical plant, to serve as a working model for energy efficient design in enclosed 19th century and 20th century urban sites and as an educational laboratory for teaching ecological and sustainable technologies to students and the public while creating jobs. The scope of our project as it relates to the BAC and the U.S. Department of Energy- NETL combined efforts includes: Task I of the project is Phase II (Green Alley). Task I encompasses various renovation activities that will demonstrate the effectiveness of permeable paving and ground water recharge systems. It will aid in the reduction of storm water

    Moving people and freight in an environmentally sustainable manner that reduces environmental pollution and health hazards is a key challenge for transport and environment policies in Europe. Present mobility patterns of passenger and freight transport in Central and Eastern Europe do not correspond to the objectives of sustainable development. This paper presents the results of a transport futures study for the CEI region as a whole using backcasting methodology with long-term sustainability criteria to be met by 2030. Achieving environmentally sustainable transport (EST) doesn't mean less transport and mobility than we have today, but it means primarily maintaining a balanced modal split that results in less environmental and health impacts than it would be under projected future trends. Rail, trams, busses and new forms of flexible inter-modal public transport mobility would have to take a large share and rail transport for passenger and freight as well as inland shipping would have to be nearly doubled by 2030 while road freight could still increase if it is based on alternative fuels reducing its impacts. Technological advancements for passenger cars and lorries, fuels and infrastructure will play an important part to achieve EST, but also ''smart'' mobility management (e.g. transport avoidance, increasing load factors and modal shift), innovative mobility services and freight logistics would be critical. The implementation of these policies and strategies will require coherent and comprehensive packages of instruments and measures, including: economic instruments, regulatory instruments, changes in infrastructure investment, mobility management, information and education programmes as well as better integration of land use, transport and environment policies. Realising EST will provide new opportunities for businesses to develop and invest in innovative solutions for passenger and freight transport. Overall, achieving EST would constitute a net benefit for

    In support of the mission-specific challenges of aeronautics and space exploration, NASA Ames produces a wealth of research and technology advancements with significant relevance to larger issues of planetary sustainability. NASA research on NexGen airspace solutions and its development of autonomous and intelligent technologies will revolutionize both the nation's air transporation systems and have applicability to the low altitude flight economy and to both air and ground transporation, more generally. NASA's understanding of the Earth as a complex of integrated systems contributes to humanity's perception of the sustainability of our home planet. Research at NASA Ames on closed environment life support systems produces directly applicable lessons on energy, water, and resource management in ground-based infrastructure. Moreover, every NASA campus is a 'city'; including an urbanscape and a workplace including scientists, human relations specialists, plumbers, engineers, facility managers, construction trades, transportation managers, software developers, leaders, financial planners, technologists, electricians, students, accountants, and even lawyers. NASA is applying the lessons of our mission-related activities to our urbanscapes and infrastructure, and also anticipates a leadership role in developing future environments for living and working in space.

    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

    Urban Transport is an important sector to accomplish the goal of sustainable development in Pakistan. This is important because of the high growth of the transport sector's energy consumption, road crashes and greenhouse gas emissions. This becomes significant in the Pakistani cities where motor vehicle fleet is growing at two to three times the rate of population. Transport Policies has resulted high growth of urban road traffic, increasing air and noise pollution throughout the country. This situation raised the question how to achieve sustainable urban transport in the mega cities of Pakistan? Development of sustainable urban transport indicators will provide an opportunity to analyze current transport policies to assess Pakistan progress towards or away from sustainability. Medium Term Development Framework (2005-10) has selected to analyze against establish sustainable urban transport indicators for Pakistan. On the basis of analysis, it has found that MWF has tried to address transport problem in a piecemeal manner, rather than adopting a holistic approach. Implementing MTDF policies on transport is not fully matched with a long term commitment to achieving sustainable development in Pakistan. (author)

  18. In search of sustainable transport systems

    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.

    The overall objective of this project was to demonstrate, through a series of real-world applications of existing technology, the benefits to the University of Nevada, Reno and the community, of various sustainability efforts. The project was very successful and has stimulated the Campus to take on more projects after seeing the successes of those initial ones funded through this project. The three areas of this work could broadly be described as energy efficiency, renewable energy and recycling. Under the first project, the campus did several projects replacing or changing heating and cooling systems, using state funding. The DOE funding initially funded the replacement of lights in one campus parking garage with LED lights. Subsequently, the campus facilities group recognized how effective this was and leveraged funds to do the other two garages. Similarly with the renewable energy project, once the first system was installed and working well, the campus committed funds to more than double that system. Lastly, the recycling efforts expanded the use and awareness on campus and led the campus to begin using a single-stream recycling program once it became available in this area, hopefully leading to more participation by the campus community. Thus, overall the project areas each did what they were intended to do, which was to demonstrate the usefulness of these sustainability programs and thus encourage the campus to do more. All this great work helps the campus’ goals overall, but without additional effort would not reach beyond the campus. This was the objective of the education and outreach effort. The combination of events, websites, and videos enabled us to reach many key decision makers and at the same time provide a long-term presence on the web that we can use to further educate people. The overall goals were met or exceeded and will continue to pay dividends into the future.

    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

    Between 2006-2008 the EU India Sustainable Energy Initiative (EISEEI) has supported marketing, implementation and enforcement of the Indian Energy Conservation Act, which came into force in 2002 - on state and local level. Market oriented five-year action plans were prepared, which are implemented by State Designated Agencies (SDA) in charge of energy efficiency measures in their respective states. Each Energy Conservation (EC) action plan states the foreseen activities for the next five years as well as general policies, a mission, and a vision relating to energy efficiency. The EISEEI project activities focused on facilitating a moderated dialogue between India and Europe as well as among the SDAs in order to support the preparation of action plans and operational plans. Furthermore, domestic and overseas trainings for SDA staff and the know-how exchange between policy makers, opinion leaders and professionals in these areas were facilitated. During the duration of the project the Indian Ministry of Power decided to apply the same methodology for 24 more SDAs to cover all Indian states. While the initial 6 pilot states were supported with EU and German development aid funds, the enlargement was 100% financed by the Indian government. The paper will highlight the efforts and results of mainstreaming energy efficiency at various consumer levels (from industry to households) in India. The paper will encompass also the involvement of various agencies and institutional structures as well as the operational experiences with the implementation of the action plan on energy efficiency in one of the fastest growing economies in the world.

    2013-12-01

    Deltas are economic and environmental hotspots, food baskets for many nations, home to a large part of the world population, and hosts of exceptional biodiversity and rich ecosystems. Deltas, being at the land-water interface, are international, regional, and local transport hubs, thus providing the basis for intense economic activities. Yet, deltas are deteriorating at an alarming rate as 'victims' of human actions (e.g. water and sediment reduction due to upstream basin development), climatic impacts (e.g. sea level rise and flooding from rivers and intense tropical storms), and local exploration (e.g. sand or aggregates, groundwater and hydrocarbon extraction). Although many efforts exist on individual deltas around the world, a comprehensive global delta sustainability initiative that promotes awareness, science integration, data and knowledge sharing, and development of decision support tools for an effective dialogue between scientists, managers and policy makers is lacking. Recently, the international scientific community proposed to establish the International Year of Deltas (IYD) to serve as the beginning of such a Global Delta Sustainability Initiative. The IYD was proposed as a year to: (1) increase awareness and attention to the value and vulnerability of deltas worldwide; (2) promote and enhance international and regional cooperation at the scientific, policy, and stakeholder level; and (3) serve as a launching pad for a 10-year committed effort to understand deltas as complex socio-ecological systems and ensure preparedness in protecting and restoring them in a rapidly changing environment. In this talk, the vision for such an international coordinated effort on delta sustainability will be presented as developed by a large number of international experts and recently funded through the Belmont Forum International Opportunities Fund. Participating countries include: U.S., France, Germany, U.K., India, Japan, Netherlands, Norway, Brazil, Bangladesh

    Secondary products from the industry - e.g. by-products of food and paper/pulp industry - can be used to manufacture new liquid biofuels or fuel components. A particularly interesting alternative is provided by butanol, which can be produced from biomass, since it seems to be most suitable for replacing petrol as fuel in gasoline engines. Besides, it is very energy efficient and also suitable to be produced on an industrial scale. Production of biobutanol and other higher alcohols is studied in the research project 'New, innovative sustainable transportation fuels for mobile applications; from biocomponents to flexible liquid fuels (SusFuFlex)'. The project is carried out as a joint project between the University of Oulu and Aabo Akademi University. It is financied by the Academy of Finland in 2008-2011, within the research programme for Sustainable Energy. Research focuses on the production of higher bioalcohols and other compounds suitable as oxygenates (e.g. butanol, pentanol, mixed alcohols; e.g. glycerine ethers, glycerol carbonate). The objectives of the research are (1) to evaluate the old and novel procedures for microbiological production of butanol, higher alcohols and oxygenates as fossil fuel substitutes, (2) to develop and optimize catalytic materials and chemical reaction routes for the production of higher alcohols and other bio-derived compounds applicable as gasoline fuel and its additives, (3) to conduct a sustainability analysis of the processes to be developed, to analyze the atom economy of the new processes and to make a preliminary economical analysis, and (4) to integrate the processes and know-how developed by the research groups

  19. Heterogeneous Initiators for Sustainable Polymerization Processes

    Science.gov (United States)

    Jones, Matthew D.

    One of the main challenges facing the twenty-first century is the need to produce chemicals from renewable resources. The dwindling supplies of fossil fuels coupled with instability in supply mean that technologies that were once deemed too expensive are now becoming more economically viable options. The majority of man-made polymers are derived from crude oil based monomers. However, in recent years a tremendous effort has been channeled into the preparation of polymers from sustainable chemicals. Two classic examples are polylactide (derived from corn starch) and polycarbonates (prepared directly from CO2). This chapter serves as an introduction into these two polymers and reviews the literature associated with heterogeneous catalyst for the polymerizations, concentrating on approaches describing the heterogenization of homogeneous catalysts.

    Full Text Available The purpose of this paper is to identify and analyse the current practices implemented in global universities for achieving sustainability throughout campus operations. This study adopted a web content analysis method where 30 international green universities’ websites have been thoroughly examined to identify common initiatives implemented to achieve sustainability through campus operations. The findings are ranked based on the implementation of these initiatives by participating universities. From the websites reviewed, as much as 31 initiatives have been identified as common initiatives frequently implemented by green universities to achieve sustainability in campus operations. It was found that the common initiatives frequently implemented by most of the universities include ‘Provide bin with clearly marked signs to increase the number of recycling items’, and ‘Generate electricity on campus by establishing power generation plants’ with 87% and 83% respectively. This paper fills the gap by presenting the investigation of sustainability initiatives from some of the major green universities internationally. It is suggested that higher education institutions, particularly Malaysian universities, initiate or manage their implementation of sustainable campus operation (SCO initiatives based on the findings of this research.

    The purpose of this paper is to document the extent to which Brazilian companies in retail channels have committed to adopting environmental sustainability measures, goals and strategies for waste disposal in the evaluation and planning of sustainable transportation. This paper also aims to examine the different viewpoints of sustainability issues and the preventive actions taken by companies in terms of controlling carbon dioxide emissions and proper disposal of tires, lubricant oils, accessories and spare parts. Finally, taking the perspective of these companies, this paper examines their difficulties in meeting environmental regulations. The research involved a survey completed by 185 representatives of different types of companies, including shippers (represented by manufacturers), LSPs (logistics service providers) and carriers. The non-linear canonical correlation was calculated to verify the opinions of these representatives from different companies regarding issues that impact on the environment, the preventive actions they adopt to reduce their environmental impact and their difficulties in meeting environmental regulations. The results show that shippers and LSPs have the same perceptions regarding these sustainability issues and preventive actions. In addition, the companies perceive high costs and the lack of training for their partners as the major challenges experienced in addressing these issues and undertaking preventive actions. Therefore they need to plan their transportation activities. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2018-02-01

    Cities become more vulnerable to climate change impacts causing by urbanization, economic growth, increasing of energy consumption and carbon dioxide (CO2) emissions. People who live in the cities have already been affected from the impacts in terms of socioeconomic and environmental aspects. Sustainable transport plays the key role in CO2 mitigation and contributes positive impacts on sustainable development for the cities. Several studies in megacities both in developed and developing countries support that mass transit system is an important transportation mode in CO2 mitigation and sustainable transport development. This paper aims to study key factors of low carbon development strategy for sustainable transport. The Bangkok Mass Rapid Transit System (MRT) located in Bangkok was the study area. Data collection was using semi-structured in-depth interview protocol with thirty respondents consisting of six groups i.e. governmental agencies, the MRT operators, consulting companies, international organizations, non-profit organizations, and experts. The research findings highlighted the major factors and supplemental elements composing of institution and technical capacity, institutional framework, policy setting and process, and plan of implementation that would support more effective strategic process for low carbon development strategy (LCDS) for sustainable transport. The study would highly recommend on readiness of institution and technical capacities, stakeholder mapping, high-level decision- makers participation, and a clear direction of the governmental policies that are strongly needed in achieving the sustainable transport.

  20. Sustainable Urban Transport in the Developing World: Beyond Megacities

    Directory of Open Access Journals (Sweden)

    Dorina Pojani

    2015-06-01

    Full Text Available Megacities have frequently received a disproportionate amount of attention over other sizes of cities in recent discourse on urban sustainability. In this article, the authors argue that a focus on smaller and medium-sized cities is crucial to achieving substantial progress towards more sustainable urban development, not only because they are home to at least a quarter of the world’s population but because they also offer great potential for sustainable transformations. In principle, their size allows for flexibility in terms of urban expansion, adoption of “green” travel modes, and environmental protection. At the same time, smaller and medium-sized cities often have fewer resources to implement new transport measures and can be more vulnerable to fluctuations in the world economy. This article critically reviews the potential role and impact of nine commonly considered options for sustainable urban transport in cities in developing countries: (1 road infrastructure; (2 rail-based public transport; (3 road-based public transport; (4 support for non-motorized travel modes; (5 technological solutions; (6 awareness-raising campaigns; (7 pricing mechanisms; (8 vehicle access restrictions; and (9 control of land-uses. Drawing on international research and examples of policies to reduce the environmental impacts of transport in urban areas, this article identifies some key lessons for sustainable urban transport in smaller and medium-sized cities in developing countries. These lessons are certainly not always identical to those for megacities in the global south.

    Sustainable transport is an urging issue on a few accounts: The transport sector was responsible for 23% global CO{sub 2} emission in 2007. It also has a number of other effects like air and noise pollution, land use etc. These effects are especially relevant in cities, where already half of the world's population is living today. With a growing world population and ongoing urbanisation the number and share of city dwellers will rise considerably in the next decades. Thus, sustainability in urban transport becomes increasingly important. This report first provides a short overview of the most important data behind the sustainability problems in urban transport. Then the question is addressed, what sustainable mobility is and where the main obstacles are on the path to more sustainability. The central part of the study deals with the most important policies and instruments enhancing sustainable (urban) mobility. The main feature of each section within that part of the study is the combination of theoretical background information and arguments with case studies from developing and transition countries. Accordingly, the reader gets an idea of the vast range of available instruments in order to promote sustainable mobility. But it is also shown that it is not only necessary but also possible to introduce or enhance sustainable urban transport regardless of the income position of the specific region, country or city. Besides, success factors for different instruments are identified, thereby deriving promising routes for countries or a group of countries according to their state of economic development. (orig.)

    Rogat, J.; Hinostroza, M. [UNEP Risoe Centre (Denmark)

    2007-05-15

    The rapid growth of Latin American cities beginning in the 70s has led to, among other things, growing mobility and demand for transportation. The lack of efficient, reliable and safe public transport systems has promoted the switch away from buses and trains towards private cars. Some of the impacts of a steadily increasing car fleet have been increased congestion, number of accidents and environmental deterioration. Recognising the potential implications of such a development, policy makers and officials found it necessary and went ahead to reformulate transport policies with the aim of providing safe, cost-effective and environmental-friendly public transport systems. Bus rapid transit (BRT) became the answer in a number of Latin American cities. The successful experiences of Curitiba in Brazil and Bogota in Colombia have served as the source of inspiration for other cities in Latin America, Asia, Europe and the USA. Thus, the BRT represents a unique example of South-South, South-North technology transfer. This paper presents some of the Latin American experiences and discusses their achievement and drawbacks.

  9. Managing Knowledge to Promote Sustainability in Australian Transport Infrastructure Projects

    Directory of Open Access Journals (Sweden)

    Jay Yang

    2015-06-01

    Full Text Available To deliver tangible sustainability outcomes, the infrastructure sector of the construction industry needs to build capacities for the creation, application and management of ever increasing knowledge. This paper intends to establish the importance and key issues of promoting sustainability through knowledge management (KM. It presents a new conceptual framework for managing sustainability knowledge to raise the awareness and direct future research in the field of transport infrastructure, one of the fast growing sectors in Australia. A holistic KM approach is adopted in this research to consider the potential to “deliver the right information to the right person at the right time” in the context of sustainable development of infrastructure. A questionnaire survey among practitioners across the nation confirmed the necessity and identified priority issues of managing knowledge for sustainability. During infrastructure development, KM can help build much needed industry consensus, develop capacity, communicate decisions, and promote specific measures for the pursuit of sustainability. Six essential elements of the KM approach and their priority issues informed the establishment of a conceptual KM framework. The transport infrastructure sector has come to realise that development must not come at the expense of environmental and social objectives. In practice however, it is facing extensive challenges to deliver what has been promised in the sustainability agenda. This research demonstrates the importance of managing sustainability knowledge, integration of various stakeholders, facilitation of plans and actions and delivery of tangible benefits in real projects, as a positive step towards meeting these challenges.

  10. Sustainability assessment for the transportation environment of Darjeeling, India.

    Nag, Dipanjan; Paul, Subrata Kr; Saha, Swati; Goswami, Arkopal K

    2018-05-01

    Darjeeling is an important tourist hill town of West Bengal, India. It suffers from an acute problem of transportation, particularly during its peak tourist seasons due to limited road space, inadequate public transport facilities and indiscriminate use of automobiles. This hill town was originally designed for a population of 10,000, but over the years, it has come face-to-face with rapid urbanization, a rising population of both tourists and residents and intensifying motor vehicle usage. These factors together are posing a threat to its transport environment. This study identifies the Sustainable Transport Indicators (STIs) available in the existing literature to identify the critical stretches using Analytical Hierarchy Process (AHP) based on experts' consensus. It was found that the experts placed emphasis on the mobility of the town, talking about vehicular impact on air pollution and encroachment of roads as the main issues affecting the sustainability of the transport environment. Thereafter, policy-level interventions have been suggested in accordance with the identified sustainability issues. We trust that other tourist hill towns with issues similar to Darjeeling could easily emulate the study methodology to assess their transport environment sustainability, or replicate on the lines of the recommended policy interventions.

    Is transportation getting more sustainable? If not, would we know what to do? This paper defines sustainable transport and describes indicators of sustainable transport, which measure the environment impacts of transport (including green-house gas emissions), the financial health of the system, safety, and access. Indicators are particularly important for developing countries because congestion, safety, air pollution, and the economic health of transport providers are usually poor. Illustrative examples are given from cites in the Partnership for Sustainable Urban Transport in Asia, or PSUTA . Future work will reveal the full quantitative picture of these three cities. As tools, indicators summarize trends and relationships among quantities that describe the most important activities, outputs, and side effects - both positive and negative - of transportation activity. Indicators permit diagnosis, evaluation of costs, benefits, and time frame of cures, prognosis based on the cures implemented, evaluation of progress against a base line, rebalancing of the system if goals are not being achieved, and marketing of results. Indicators also draw stakeholders into an objective discussion of each of these steps. Indicators of governance map their roles in solving problems. Indicators of sustainable passenger transport are being developed and deployed with authorities in Pune (India), Hanoi (Viet Nam), and Xi'an (China). The paper describes how authorities assess needs to determine what indicators are necessary (at what precision), mapping the gap of information required to develop indicators, bridging the gap of information and funding data and analysis, and crossing the bridge to commit to a quantitative approach to policymaking and evaluation. The paper concludes with recommendations on both the most important indicators required for the cities, and the most important policy steps required to improve transportation, focusing on emissions (including green-house gases

  13. Multi-stakeholder initiatives in sustainable supply chains: Putting sustainability performance in context

    Directory of Open Access Journals (Sweden)

    Cory Searcy

    2017-12-01

    Full Text Available The purpose of this article is to explore the role of multi-stakeholder initiatives (MSIs in sustainable supply chains. I argue that MSIs are needed to help establish and institutionalize the natural and social thresholds in which a sustainable supply chain must operate. While a multitude of MSIs relevant to supply chains already exist, they do not yet adequately address sustainability thresholds. Building on theory and literature, I elaborate on four interrelated roles for MSIs in this area: (1 providing learning platforms, (2 developing standards, (3 developing enforcement mechanisms, and (4 issuing labels and certifications. All four roles emphasize the need for supply chains to operate within the thresholds set by nature and society. Staying within thresholds is what distinguishes between sustainable and unsustainable supply chains. The four roles form part of a broader conceptual framework outlining a way forward for MSIs in sustainable supply chains. Different MSIs could address one or more of these roles. I argue that all MSIs must be developed with special attention to their input and output legitimacy. Stakeholders from both within and beyond the supply chain must be involved in developing and implementing a MSI for it to be viewed as legitimate. I note that the conceptual framework presented here is a starting point. It would benefit from further testing and refinement. For example, future work could add further specificity to the four roles I discuss. Future research could also focus on integrating economic thresholds for sustainable supply chains into the framework.

    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.

To implement this concept, a process has been designed to co-feed a biomass gasifier with H2 and CO2 recycled from the H2-CO to liquid conversion reactor. Modeling of this biomass to liquids process has identified several major advantages of the H2CAR process. (i) The land area needed to grow the biomass is CAR process shows the potential to supply the entire United States transportation sector from that quantity of biomass. (iii) The synthesized liquid provides H2 storage in an open loop system. (iv) Reduction to practice of the H2CAR route has the potential to provide the transportation sector for the foreseeable future, using the existing infrastructure. The rationale of using H2 in the H2CAR process is explained by the significantly higher annualized average solar energy conversion efficiency for hydrogen generation versus that for biomass growth. For coal to liquids, the advantage of H2CAR is that there is no additional CO2 release to the atmosphere due to the replacement of petroleum with coal, thus eliminating the need to sequester CO2.

    2004-01-01

    This paper reports on a research project that aimed to identify and assess measures which could be used to reduce travel demand while maintaining economic growth and enhancing environmental quality. The research methodology involved a detailed review of past research; contact with over 600 experts from around Europe and elsewhere for ideas on potential measures; detailed questionnaires from over 100 of these experts; and a series of three panel sessions held in different parts of Europe, each of which involved around 16 experts debating the merits of different measures and identifying case study evidence of their effectiveness. The end result was a short list of 13 measures, indicative of broad types, which are considered to be effective, and an indication of their effectiveness if applied across the European Union. Seven illustrative measures are discussed which stand out from the results as having proven potential (though not necessarily at a European scale) to influence transport intensity and/or unit environmental load whilst not having large detrimental effects on GDP. These are the areas where it is felt that European transport policy could most usefully be focussed in terms of decoupling of transport demand and economic growth

  20. Transportation energy in global cities: Sustainable transportation comes in from the cold?

    2001-01-01

    The energy, environmental and social benefits of sustainable transportation, i.e, public transit, biking and walking, have long been recognized but are now mainstream in global and local transportation policy debates. However, the economic value of sustainable transportation has always been seen as secondary, unless many external costs were included. The results of a new global study show that cities with significant sustainable transportation systems have reduced costs on road construction and maintenance; better operating cost recovery and fuel-efficiency; fewer road accidents and less air pollution. In overall terms, the percentage of city funds going to transportation is reduced. The data show that cities with the most roads have the highest transportation costs and the most rail-oriented cities have the lowest. Further, the most sprawling cities have the highest direct and indirect costs for transportation. Thus, strategies to contain sprawl, to reurbanize, to build new rail systems info car-dependent suburbs with focussed sub-centers, and to facilitate biking and walking, not only will improve energy efficiency but will reduce costs to the economy of a city. Strategies that build freeways and add to sprawl will do the opposite. Trends indicate that moves toward sustainable urban patterns are beginning. The need to operationalize sustainable transportation strategies in planning and engineering practice and in the politics of infrastructure funding remains a major challenge. Some cities are showing how this can be done. (author)

    Business travel has been relatively neglected in strategies to promote sustainable travel. A two-stage approach is taken beginning by showing how sustainability of business travel is relevant not only environmentally, but also from an economic and social perspective. On the one hand, this form of travel helps to generate jobs in numerous business sectors, not only in transportation. On the other hand, the social dimension cannot be ignored either, since business travel is often a source of fa...

    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

    2015-03-01

    Full Text Available Recent efforts have helped to augment the knowledge base, the public policies, professional practices and funding required for sustainable transportation. I argue that the progress made is laudable but caution that it may vanish rapidly if, due to a number of factors and events, including the need to ameliorate the consequences of the global financial crisis, attention is redirected at resuming a nation building project centred on land development and automobility. This paper uses a fourfold-criterion to analyse the new specialization in non-motorized transportation planning and to discuss the dilemma of technology transfer among communities and countries.

    Jahr, E; Eldevik, S; Eikeseth, S

    2000-01-01

    This study investigated the acquisition, transfer, and maintenance of cooperative play in six children with autism. Two approaches were compared. In one approach, the participants observed two models engaging in cooperative play, before taking the place of one of the models while the play episode just observed was repeated. The second approach was identical to the first except that the participants were now required to verbally describe the modeled play episode before taking the place of one of the models. During training, modeled play episodes varied across play topics, and the criterion for mastery was first trial learning of novel play episodes. A nonconcurrent multiple baseline design across participants was applied. The results showed that the participants failed to acquire cooperative play until the verbal description was included in the training procedure. Following training with verbal description, all participants: a) could initiate episodes and sustain episodes initiated by their play partner; b) were able to take turns in episodes that were considerably longer than the episodes practiced during training; c) varied their play within and between play episodes; and, d) transferred those skills across play partners, settings, and time.

  13. Mixed Transportation Network Design under a Sustainable Development Perspective

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available A mixed transportation network design problem considering sustainable development was studied in this paper. Based on the discretization of continuous link-grade decision variables, a bilevel programming model was proposed to describe the problem, in which sustainability factors, including vehicle exhaust emissions, land-use scale, link load, and financial budget, are considered. The objective of the model is to minimize the total amount of resources exploited under the premise of meeting all the construction goals. A heuristic algorithm, which combined the simulated annealing and path-based gradient projection algorithm, was developed to solve the model. The numerical example shows that the transportation network optimized with the method above not only significantly alleviates the congestion on the link, but also reduces vehicle exhaust emissions within the network by up to 41.56%.

    2014-01-01

    Full Text Available City is the place of the largest concentration of economic and social activities, and the delivery of goods is a prerequisite for the maintenance of urban life and business activities for achieving wealth and development of the city. Logistics systems and processes that enable the realization of commodity flows support employment and generate income, but may also have negative impacts on all essential functions of the city. Therefore, logistics plays an important role in the competitiveness of urban areas and should be an integral part of the city's economy. From the perspective of sustainable development, i.e. social, environmental and economic efficiency, logistics processes primarily urban freight transport, are far from optimal. The growth of road freight transport and traffic congestion, air pollution and other negative impacts on the environment, inefficient use of land and the rising costs of delivery of goods affect the definition and exploration of different initiatives of city logistics. This paper describes the initiatives that do not require large infrastructure investments and do not change the existing urban context, but can improve its sustainability.

    2013-01-01

    This paper demonstrates a systems framework for assessment of environmental impacts from ‘green initiatives’, through a case study of meso-scale, anthropogenic–biogenic interactions. The following cross-sectoral green initiatives, combining the emerging trends in the North East region of the United Kingdom, have been considered – increasing the vegetation cover; decarbonising road transport; decentralising energy production through biomass plants. Two future scenarios are assessed – Baseline 2 020 (projected emissions from realisation of policy instruments); Aggressive 2 020 (additional emissions from realisation of green initiatives). Resulting trends from the Aggressive 2 020 scenario suggest an increase in emissions of pollutant precursors, including biogenic volatile organic compounds and nitrogen dioxide over the base case by up to 20% and 5% respectively. This has implications for enhanced daytime ozone and secondary aerosols formation by up to 15% and over 5% respectively. Associated land cover changes show marginal decrease of ambient temperature but modest reductions in ammonia and ambient particulates. -- Highlights: • A systems scale assessment framework for emerging green initiatives is proposed. • Interactions between urban greenspace, greener vehicles and bioenergy system examined. • Altering future emissions profile enhances synthesis of photochemical precursors. • Incorporating whole-system evaluation deemed vital for well-rounded sustainability. -- Systems scale implication for air pollution was assessed across three sectors of emerging green initiatives-energy, transport and ecosystem

This paper discusses the role of parking as part of the policy packages for strategic planning aimed at increasing the sustainability of urban and metropolitan areas. In particular, the integration of parking strategies in a comprehensive vision for the future of a city may significantly improve the allocation of resources and the reduction of the overall environmental externalities. The role of parking in the strategic planning of cities is discussed through the analysis of several recent projects in the city of Bari (Italy. The paper discusses the way these projects are linked (or eventually not linked to broader strategies for urban mobility, and how they might be coordinated into policy packages that promote more sustainable transportation. The use of an integrated land use transportation modeling approach to simulate the long-term evolution of the urban area may significantly contribute to estimate the long-term effects of the proposed policies. This approach may successfully support the process of policy evaluation and the selection of the optimal strategies to implement.

Apart from Sao Paulo, leading city in the Americas, another eight cities located in Europe and Asia takes part in the project. One of the Brazilian project's goals is to evaluate ethanol usage as diesel fuel replacement in public transport buses by comparatively following the operational output of the experimental fleet, taking as reference an equivalent diesel bus. The utilized test vehicles will be evaluated and monitored to demonstrate ethanol energetic efficiency and, after the results the BEST project and the European Union will set a blue print for public policies to incentive ethanol usage in the urban public transport. The results will allow identifying technical and economical barriers that will eventually overlap the viability process of this technology in the Brazilian public transport. (author)

  8. Assessing policies towards sustainable transport in Europe: an integrated model

    International Nuclear Information System (INIS)

    Zachariadis, Theodoros

    2005-01-01

    A transport simulation and forecast model is presented, which is designed for the assessment of policy options aiming to achieve sustainability in transportation. Starting from a simulation of the economic behaviour of consumers and producers within a microeconomic optimisation framework and the resulting calculation of the modal split, the allocation of the vehicle stock into vintages and technological groups is modelled. In a third step, a technology-oriented algorithm, which incorporates the relevant state-of-the-art knowledge in Europe, calculates emissions of air pollutants and greenhouse gases as well as appropriate indicators for traffic congestion, noise and road accidents. The paper outlines the methodology and the basic data sources used in connection with work done so far in Europe, presents the outlook according to a 'reference case' run for the 15 current European Union Member States up to 2030, displays aggregate results from a number of alternative scenarios and outlines elements of future work

  9. Carbon dioxide emissions from passenger transport in China since 1949: Implications for developing sustainable transport

    International Nuclear Information System (INIS)

    Loo, Becky P.Y.; Li, Linna

    2012-01-01

    This paper traces the historical evolution and spatial disparity of CO 2 emissions from passenger transport in China. The general trends of CO 2 emissions from four passenger transport modes are estimated by both the distance-based and fuel-based methods. The results suggest that CO 2 emissions from road transport represented the leading source of passenger transport CO 2 emissions in China. Moreover, they have continued to grow rapidly. Air transport was the second largest contributor since 1998. Emissions from rail and water transport have remained relatively stable with lower emission intensity. At the provincial level, great regional disparity was noticeable, especially in road transport. Moreover, the decomposition analysis shows that income growth was the principal factor leading to the growth of passenger transport CO 2 emissions in China for both the 1949–1979 and 1980–2009 periods. The second most important factor was increased transport intensity and modal shifts for the former and the latter period, respectively. The main factor contributed to emission reduction was the lower emission intensity supported by policies, although the effect was weak. In the future, more policies to encourage modal shifts toward sustainable transport modes and travel reduction should be encouraged. - Highlights: ► CO 2 emissions from passenger transport in China were estimated. ► Road transport was the largest contributor to CO 2 emission. Air transport followed. ► Factors influencing CO 2 emissions growth are analyzed by decomposition analysis. ► Income growth, higher travel intensity and modal shift were driving CO 2 emissions up. ► Policies to promote modal shifts and travel demand reduction should be encouraged.

  10. Future Transportation with Smart Grids and Sustainable Energy

    2009-10-01

    Full Text Available Transportation is facing fundamental change due to the rapid depletion of fossil fuels, environmental and health problems, the growing world population, rising standards of living with more individual mobility and the globalization of trade with its increasing international transport volume. To cope with these serious problems benign, renewable energy systems and much more efficient drives must be multiplied as rapidly as possible to replace the polluting combustion engines with their much too low efficiency and high fuel logistics cost. Consequently the vehicles of the future must be non-polluting and super-efficient, i.e. electric. The energy supply must come via smart grids from clean energy sources not affecting the health, climate and biosphere. It is shown how this transition to the clean, sustainable energy age is possible, feasible and why it is urgent. The important role of international ISO, IEC and ITU standards and the need for better legislation by means of the Global Energy Charter for Sustainable Development are also highlighted.

  11. Sustainable Urban Homecare Delivery with Different Means of Transport

    Directory of Open Access Journals (Sweden)

    Norina Szander

    2018-02-01

    Full Text Available Due to the increasing number of requests for homecare services, care institutions struggle to perform in urban traffic, which eventually makes travel times longer and less predictable and, therefore, leads to a declining service quality. Homecare delivery scheduling and planning tools must lead to efficient reliable routes that allow the nursing crew to make the least efforts and use the fewest institutional resources, and that consider urban sustainability goals. For the case study, a European city was selected with 58,000 people of whom 73 patients received long-term care at homes provided by 11 homecare nurses. While maximising patient satisfaction, a homecare planning algorithm considered many means of transport and minimised travel times. The study reduced the total nurses’ working hours/day by a bus and walking combination, and by comparing if nurses ride e-bikes, which respectively reduced ~35–44% of the total time that nurses spent travelling. This result is applicable to an urban environment where the public transport network is sufficient and biking is allowed on a reasonable number of roads. Better homecare management can support the efficient use of resources of health care institutions, high-quality home care and aspirations towards livable communities and sustainable development.

    Full Text Available Having IT-related capabilities is not enough to secure value from the IT resources and survive in today’s competitive environment. IT resources evolve dynamically and organisations must sustain their existing capabilities to continue to leverage value from their IT resources. Organisations’ IT-related management capabilities are an important source of their competitive advantage. Organisations can sustain these capabilities through appropriate considerations of resources at the technology-use level. This study suggests that an appropriate organisational design relating to decision rights and work environment, and a congruent reward system can create a dynamic end-user environment. This environment will be a vital source of knowledge that could help organisations to sustain their IT-related management capabilities. Analysis of data collected from a field survey demonstrates that a dynamic end-user environment, a result of a coordinated change in complementary factors, helps organisations to sustain their IT-related management capabilities. This study adds an important dimension to understanding why some organisations continue to perform better with their IT resources than others. For practice, this study suggests that organisations need to consider a comprehensive approach to what constitutes their valuable organisational resources.

    The outcomes of organ transplantation activities are greatly affected by the ability to haul organs and medical teams quickly and safely. Organ allocation and usage criteria have greatly improved over time, whereas the same result has not been achieved so far from the transport point of view. Safety and the highest level of service and efficiency must be reached to grant transplant recipients the healthiest outcome. The Italian National Transplant Centre (CNT), in partnership with the regions and the University of Bologna, has promoted a thorough analysis of all stages of organ transportation logistics chains to produce homogeneous and shared guidelines throughout the national territory, capable of ensuring safety, reliability, and sustainability at the highest levels. The mapping of all 44 transplant centers and the pertaining airport network has been implemented. An analysis of technical requirements among organ shipping agents at both national and international level has been promoted. A national campaign of real-time monitoring of organ transport activities at all stages of the supply chain has been implemented. Parameters investigated have been hospital and region of both origin and destination, number and type of organs involved, transport type (with or without medical team), stations of arrival and departure, and shipping agents, as well as actual times of activities involved. National guidelines have been issued to select organ storage units and shipping agents on the basis of evaluation of efficiency, reliability, and equipment with reference to organ type and ischemia time. Guidelines provide EU-level standards on technical equipment of aircrafts, professional requirements of shipping agencies and cabin crew, and requirements on service provision, including pricing criteria.

    The overall aim of the Finnish SIMBe project (www.SIMBe.fi) is to significantly accelerate the introduction of sustainable electric mobility in Finland. SIMBe stands for Smart Infrastructures for Electric Mobility in Built Environments. The fundamental assumption of the project is that electric (e-) mobility is inherently more sustainable than mobility based on fossil fuels. However, as has been widely recognized in the e-mobility field, the currently used batteries are expensive, often more expensive than the rest of the particular electric vehicle (EV) that they propel. There are two opposite schools of thought how to address this problem, which can be summarized as follows: a) Leave the battery in peace, as it is precious. Use it only to propel the EV of which it is an integral part. Use it instead of fuel, and do not use it for any other applications. The EV's sole purpose is that of a transportation device. b) Make as much use of the battery as possible, as it is precious. Involve vehicle to grid (V2G) or vehicle to house charging. Additionally, invent new features, meanings and services for the battery driven EV, which go distinctively beyond transport. The SIMBe project decided to opt for school (b), based on the smart energy production and distribution scenario, in which electric and hybrid vehicles' batteries will deliver energy on demand to the grid. SIMBe aims to prepare key Finnish industrial players and consumers for the transition to this new energy-transportation paradigm. But how can we replace the conservative understanding of the 'transport only' school by a holistic view of what features, meanings and services are actually possible by using a large scale fleet of 'batteries on wheels'? The Nordic Climate Festival (at) Aalto provided the unique opportunity to tap into the knowledge and creativity of students within the Nordic countries. Being properly prepared and facilitated, a workshop may provide some insights and

    Currently there are nearly 750 million ground vehicles in service worldwide. They are responsible for 50% of petroleum (oil) consumption and 60% of all greenhouse gas (GHG) emissions worldwide. The number of vehicles is forecasted to double by 2050. Therefore the environmental issues such as noise, emissions and fuel burn have become important for energy and environmental sustainability. This paper provides an overview of specific energy and environmental issues related to ground transportation. The technologies related to reduction in energy requirements such as reducing the vehicle mass by using the high strength low weight materials and reducing the viscous drag by active flow control and smoothing the operational profile, and reducing the contact friction by special tire materials are discussed along with the portable energy sources for reducing the GHG emissions such as low carbon fuels (biofuels), Lithium-ion batteries with high energy density and stability, and fuel cells. The technological challenges and opportunities for innovations are discussed.

    Full Text Available Background: For many logistics service providers and shippers sustainable transport is still a relatively recent issue, even if almost every transportation company is engaged in sustainability. Each has had different experiences with making transportation more sustainable. By looking at the efforts and successes of others sharing these experiences could help shippers and logistics service providers to obtain new innovative ideas of how to become more sustainable. The certification organization Green Freight Europe (GFE wants to develop a database for these types of experiences in order to encourage its members to generate sustainable initiatives. Method: In support of this plan, we interviewed several logistics service providers and shippers and conducted a brief survey among GFE members. Results: Sustainability forms one of the goals for all interviewed companies mainly based on cost reduction but followed closely as a tool to attract new customers. At the moment, the information obtained to keep updated on sustainability comes mainly from truck producers and not from information from best cases from other logistics service providers. Conclusions: We have found that there is a willingness to submit best cases, but also a fear that the submitter will miss his competitive advantage by telling others about his innovations.

    The Initial Atmospheric Transport (IAT) computer code was developed at Sandia National Laboratories as part of their nuclear launch accident consequences analysis suite of computer codes. The purpose of IAT is to predict the initial puff/plume rise resulting from either a solid rocket propellant or liquid rocket fuel fire. The code generates initial conditions for subsequent atmospheric transport calculations. The Initial Atmospheric Transfer (IAT) code has been compared to two data sets which are appropriate to the design space of space launch accident analyses. The primary model uncertainties are the entrainment coefficients for the extended Taylor model. The Titan 34D accident (1986) was used to calibrate these entrainment settings for a prototypic liquid propellant accident while the recent Johns Hopkins University Applied Physics Laboratory (JHU/APL, or simply APL) large propellant block tests (2012) were used to calibrate the entrainment settings for prototypic solid propellant accidents. North American Meteorology (NAM )formatted weather data profiles are used by IAT to determine the local buoyancy force balance. The IAT comparisons for the APL solid propellant tests illustrate the sensitivity of the plume elevation to the weather profiles; that is, the weather profile is a dominant factor in determining the plume elevation. The IAT code performed remarkably well and is considered validated for neutral weather conditions.

    2011-01-01

    Full Text Available With more stringent requirements for efficient utilization of energy resources within the transport industry a need for implementation of sustainable development principles has appeared. Such action will be one of competitive advantages in the future. This is especially confirmed within the road transport sector. A methodology implemented in public procurement procedures for fleet renewal regarding the calculation of road vehicles’ operational lifecycle costs has been analyzed in detail in this paper. Afore mentioned calculation comprises the costs for: vehicle ownership, energy, carbon dioxide and pollutants emissions. Implementation of this methodology allows making the choice of energy efficient vehicles and vehicles with notable positive environmental effects. The objective of the research is to assess the influence of specific parameters of vehicle operational lifecycle costs, especially energy costs and estimated vehicle energy consumption, on vehicle choice in the procurement procedure. The case of urban bus fleet in Serbia was analyzed. Their operational lifecycle costs were calculated and differently powered vehicles were assessed. Energy consumption input values were defined. It was proved that defined fleet renewal scenarios could influence unquestionable decrease in energy consumption.

    2016-11-01

    Full Text Available The article explores the complex relationships between the natural environment , tourist transport and sustainable tourism development. In order to research the impact of natural resources on tourism activity, on the one hand, and the influences of tourism on the environment, on the other hand, statistical and mathematical methods of analysis and forecast were used, namely, the analysis of the dynamics of significant indicators of the natural environment and of tourist activity, the correlation method, the Markov chains method. The analyses made lead us to the conclusion of the existence of a positive evolution of significant indicators of the natural environment, with an impact on tourist activity, such as natural parks. It has been emphasized; also, that this positive evolution has a direct influence on the attraction of visitors, specifically, foreign ones, but the intensity of this influence is average. The intensification of the actions of promotion of natural parks and, generally, of protected areas in Romania, would be a direction for attracting an increased number of visitors, with all the favourable economic consequences. On the other hand, the research has outlined the fact that, as far as the means of transportation used by tourists to visit Romania are concerned, on the first places we can see road and air transport, means of transportation which, aside from the obvious advantages for tourists, have a strong negative impact on the environment. The forecast made with the help of the Markov chains method has shown a negative trend, from the point of view of the impact on the environment, namely an increase in the share of road and air transport in the preference of foreign visitors to Romania. The current research represents a contribution to the efforts of measuring, through statistical and mathematical models, of the complex influences, in both senses, between the environment and tourist activity. Thus, an objective radiography has

  19. Life cycle assessment in support of sustainable transportation

    Eckelman, Matthew J.

    2013-06-01

    In our rapidly urbanizing world, sustainable transportation presents a major challenge. Transportation decisions have considerable direct impacts on urban society, both positive and negative, for example through changes in transit times and economic productivity, urban connectivity, tailpipe emissions and attendant air quality concerns, traffic accidents, and noise pollution. Much research has been dedicated to quantifying these direct impacts for various transportation modes. Transportation planning decisions also result in a variety of indirect environmental and human health impacts, a portion of which can accrue outside of the transit service area and so outside of the local decision-making process. Integrated modeling of direct and indirect impacts over the life cycle of different transportation modes provides decision support that is more comprehensive and less prone to triggering unintended consequences than a sole focus on direct tailpipe emissions. The recent work of Chester et al (2013) in this journal makes important contributions to this research by examining the environmental implications of introducing bus rapid transit and light rail in Los Angeles using life cycle assessment (LCA). Transport in the LA region is dominated by automobile trips, and the authors show that potential shifts to either bus or train modes would reduce energy use and emissions of criteria air pollutants, on an average passenger mile travelled basis. This work compares not just the use of each vehicle, but also upstream impacts from its manufacturing and maintenance, as well as the construction and maintenance of the entire infrastructure required for each mode. Previous work by the lead author (Chester and Horvath 2009), has shown that these non-operational sources and largely non-local can dominate life cycle impacts from transportation, again on an average (or attributional) basis, for example increasing rail-related GHG emissions by >150% over just operational emissions

  20. Predicting Reactive Transport Dynamics in Carbonates using Initial Pore Structure

    Menke, H. P.; Nunes, J. P. P.; Blunt, M. J.

    2017-12-01

    Understanding rock-fluid interaction at the pore-scale is imperative for accurate predictive modelling of carbon storage permanence. However, coupled reactive transport models are computationally expensive, requiring either a sacrifice of resolution or high performance computing to solve relatively simple geometries. Many recent studies indicate that initial pore structure many be the dominant mechanism in determining the dissolution regime. Here we investigate how well the initial pore structure is predictive of distribution and amount of dissolution during reactive flow using particle tracking on the initial image. Two samples of carbonate rock with varying initial pore space heterogeneity were reacted with reservoir condition CO2-saturated brine and scanned dynamically during reactive flow at a 4-μm resolution between 4 and 40 times using 4D X-ray micro-tomography over the course of 1.5 hours using μ-CT. Flow was modelled on the initial binarized image using a Navier-Stokes solver. Particle tracking was then run on the velocity fields, the streamlines were traced, and the streamline density was calculated both on a voxel-by-voxel and a channel-by-channel basis. The density of streamlines was then compared to the amount of dissolution in subsequent time steps during reaction. It was found that for the flow and transport regimes studied, the streamline density distribution in the initial image accurately predicted the dominant pathways of dissolution and gave good indicators of the type of dissolution regime that would later develop. This work suggests that the eventual reaction-induced changes in pore structure are deterministic rather than stochastic and can be predicted with high resolution imaging of unreacted rock.

  1. Developing a Collaborative Planning Framework for Sustainable Transportation

    Directory of Open Access Journals (Sweden)

    Okan Örsan Özener

    2014-01-01

    Full Text Available Currently, as being the highest petroleum consuming sector in the world, transportation significantly contributes to the total greenhouse gas emissions in the world. Road transportation not only is responsible for approximately 20% of the total emissions of carbon dioxide in the EU and in the US but also has a steadily increasing trend in contributing to global warming. Initiatives undertaken by authorities, such as Emission cap and trade in the EU, limit the emissions resulted from the actions of the companies and also give economic incentives to companies to reduce their emissions. However, in logistics systems with multiple entities, it is difficult to assess the responsibilities of the companies both in terms of costs and emissions. In this study, we consider a delivery network with multiple customers served by a single carrier, which executes a delivery plan with the minimum transportation cost, and allocate the resulting costs and the emissions among the customers in a fair manner. We develop allocation mechanisms for both costs and emissions. In order to develop a mechanism that provides further reduction of the emissions, we study a setting where the carrier takes the responsibility of the emissions and reflects the resulting inefficiencies while charging the customers.

    Rapidly developing diagnostic, operational, and analysis capability is enabling the first detailed local physics studies to begin in high-beta plasmas of the National Spherical Torus Experiment (NSTX). These studies are motivated in part by energy confinement times in neutral-beam-heated discharges that are favorable with respect to predictions from the ITER-89P scaling expression. Analysis of heat fluxes based on profile measurements with neutral-beam injection (NBI) suggest that the ion thermal transport may be exceptionally low, and that electron thermal transport is the dominant loss channel. This analysis motivates studies of possible sources of ion heating not presently accounted for by classical collisional processes. Gyrokinetic microstability studies indicate that long wavelength turbulence with k(subscript ''theta'') rho(subscript ''i'') ∼ 0.1-1 may be suppressed in these plasmas, while modes with k(subscript ''theta'') rho(subscript ''i'') ∼ 50 may be robust. High-harmonic fast-wave (HHFW) heating efficiently heats electrons on NSTX, and studies have begun using it to assess transport in the electron channel. Regarding edge transport, H-mode [high-confinement mode] transitions occur with either NBI or HHFW heating. The power required for low-confinement mode (L-mode) to H-mode transitions far exceeds that expected from empirical edge-localized-mode-free H-mode scaling laws derived from moderate aspect ratio devices. Finally, initial fluctuation measurements made with two techniques are permitting the first characterizations of edge turbulence

    To find a more effective method for the assessment of sustainable urban transport development, the comprehensive assessment model of sustainable urban transport development was established based on the unascertained measure. On the basis of considering the factors influencing urban transport development, the comprehensive assessment indexes were selected, including urban economical development, transport demand, environment quality and energy consumption, and the assessment system of sustainable urban transport development was proposed. In view of different influencing factors of urban transport development, the index weight was calculated through the entropy weight coefficient method. Qualitative and quantitative analyses were conducted according to the actual condition. Then, the grade was obtained by using the credible degree recognition criterion from which the urban transport development level can be determined. Finally, a comprehensive assessment method for urban transport development was introduced. The application practice showed that the method can be used reasonably and effectively for the comprehensive assessment of urban transport development.

Examples of this `win-win' approach can be found across a wide range of industries, from encouraging the reuse of hotel towels, to the construction of energy efficient buildings, to the large-scale initiatives of multi-national corporations. Although win-win strategies are generally thought to reflect positively on the organizations that employ them, here we find that people tend to respond negatively to the notion of profiting from environmental initiatives. In fact, observers may evaluate environmental win-wins less favourably than profit-seeking strategies that have no environmental benefits. The present studies suggest that how those initiatives are communicated to the general public may be of central importance. Therefore, organizations would benefit from carefully crafting the discourse around their win-win initiatives to ensure that they avoid this type of backlash.

    The International Society of Biometeorology (ISB) has covered significant breadth and depth addressing fundamental and applied societal and environmental challenges in the last 60 years. Biometeorology is an interdisciplinary science connecting living organisms to their environment, but there is very little understanding of the existence and placement of this discipline within formal educational systems and institutions. It is thus difficult to project the ability of members of the biometeorological community—especially the biometeorologists of the future—to help solve global challenges. In this paper, we ask: At present, how we are training people to understand and think about biometeorology? We also ask: What are the current tools and opportunities in which biometeorologists might address future challenges? Finally, we connect these two questions by asking: What type of new training and skill development is needed to better educate "biometeorologists of the future" to more effectively address the future challenges? To answer these questions, we provide quantitative and qualitative evidence from an educationally focused workshop attended by new professionals in biometeorology. We identify four common themes (thermal comfort and exposures, agricultural productivity, air quality, and urbanization) that biometeorologists are currently studying and that we expect to be important in the future based on their alignment with the United Nations Sustainable Development Goals. Review of recent literature within each of these thematic areas highlights a wide array of skill sets and perspectives that biometeorologists are already using. Current and new professionals within the ISB have noted highly varying and largely improvised educational pathways into the field. While variability and improvisation may be assets in promoting flexibility, adaptation, and interdisciplinarity, the lack of formal training in biometeorology raises concerns about the extent to which

    Objective To examine how attributes affecting sustainability differ across VHA organizational components and by staff characteristics. Subjects Surveys of 870 change team members and 50 staff interviews within the VA’s Mental Health System Redesign initiative. Methods A one-way ANOVA with a Tukey post-hoc test examined differences in sustainability by VISN, job classification, and tenure from staff survey data of the Sustainability Index. Qualitative interviews used an iterative process to identify “a priori” and “in vivo” themes. A simple stepwise linear regression explored predictors of sustainability. Results Sustainability differed across VISN and staff tenure. Job classification differences existed for: 1) Benefits and Credibility of the change and 2) staff involvement and attitudes toward change. Sustainability barriers were: staff and institutional resistance, and non-supportive leadership. Facilitators were: commitment to veterans, strong leadership, and use of QI Tools. Sustainability predictors were outcomes tracking, regular reporting, and use of PDSA cycles. Conclusions Creating homogeneous implementation and sustainability processes across a national health system is difficult. Despite the VA’s best evidence-based implementation efforts, there was significant variance. Locally tailored interventions might better support sustainability than “one-size-fits all” approaches. Further research is needed to understand how participation in a QI collaborative affects sustainability. PMID:21971024

    To examine how attributes affecting sustainability differ across Veterans Health Administration organizational components and by staff characteristics. Surveys of 870 change team members and 50 staff interviews within the Veterans Affairs' Mental Health System Redesign initiative. A 1-way ANOVA with a Tukey post hoc test examined differences in sustainability by Veteran Integrated Service Networks, job classification, and tenure from staff survey data of the Sustainability Index. Qualitative interviews used an iterative process to identify "a priori" and "in vivo" themes. A simple stepwise linear regression explored predictors of sustainability. Sustainability differed across Veteran Integrated Service Networks and staff tenure. Job classification differences existed for the following: (1) benefits and credibility of the change and (2) staff involvement and attitudes toward change. Sustainability barriers were staff and institutional resistance and nonsupportive leadership. Facilitators were commitment to veterans, strong leadership, and use of quality improvement tools. Sustainability predictors were outcomes tracking, regular reporting, and use of Plan, Do, Study, Adjust cycles. Creating homogeneous implementation and sustainability processes across a national health system is difficult. Despite the Veterans Affairs' best evidence-based implementation efforts, there was significant variance. Locally tailored interventions might better support sustainability than "one-size-fits-all" approaches.

  17. Relationship between sustainable development initiatives and improved company financial performance: A South African perspective

    Directory of Open Access Journals (Sweden)

    Darelle Groenewald

    2016-05-01

    Research purpose: The study analysed the relationship between sustainability performance and FP in South African listed companies. Motivation for the study: Some South African listed companies acknowledge in their sustainability reports that there is a link between sustainability development and long-term shareholder value. This implies that FP is linked to sustainable development performance. This relationship has not been researched for South African listed companies and therefore needs to be investigated. Research design, approach and method: A similar research method was used as for an international study. Forty-five listed South African companies were selected as the sample. Their sustainable development reports were used for analysis. Data were analysed with the use of content and a canonical correlation analysis. Main findings: The results of the study revealed that an overall positive relationship exists between sustainability performance and FP. Practical implications: South African companies that have a high involvement and focus on specific sustainable development initiatives that are integrated into overall sustainable development strategy can deliver improved FP for the organisation and deliver long-term value to its shareholders. Contribution: Six sustainable development aspects were found to be significantly correlated with improved FP and if incorporated into a company’s sustainable development strategy can lead to increased successes.

    To describe the development and application of the School Food Environment Assessment Tools and a novel scoring system to assess the integration of healthy and environmentally sustainable food initiatives in elementary and secondary schools. The cross-sectional study included direct observations of physical food environments and interviews with key school personnel regarding food-related programmes and policies. A five-point scoring system was then developed to assess actions across six domains: (i) food gardens; (ii) composting systems; (iii) food preparation activities; (iv) food-related teaching and learning activities; and availability of (v) healthy food; and (vi) environmentally sustainable food. Vancouver, Canada. A purposive sample of public schools (n 33) from all six sectors of the Vancouver Board of Education. Schools scored highest in the areas of food garden and compost system development and use. Regular integration of food-related teaching and learning activities and hands-on food preparation experiences were also commonly reported. Most schools demonstrated rudimentary efforts to make healthy and environmentally sustainable food choices available, but in general scored lowest on these two domains. Moreover, no schools reported widespread initiatives fully supporting availability or integration of healthy or environmentally sustainable foods across campus. More work is needed in all areas to fully integrate programmes and policies that support healthy, environmentally sustainable food systems in Vancouver schools. The assessment tools and proposed indicators offer a practical approach for researchers, policy makers and school stakeholders to assess school food system environments, identify priority areas for intervention and track relevant changes over time.

  9. Observations of bromine monoxide transport in the Arctic sustained on aerosol particles

    Directory of Open Access Journals (Sweden)

    P. K. Peterson

    2017-06-01

    Full Text Available The return of sunlight in the polar spring leads to the production of reactive halogen species from the surface snowpack, significantly altering the chemical composition of the Arctic near-surface atmosphere and the fate of long-range transported pollutants, including mercury. Recent work has shown the initial production of reactive bromine at the Arctic surface snowpack; however, we have limited knowledge of the vertical extent of this chemistry, as well as the lifetime and possible transport of reactive bromine aloft. Here, we present bromine monoxide (BrO and aerosol particle measurements obtained during the March 2012 BRomine Ozone Mercury EXperiment (BROMEX near Utqiaġvik (Barrow, AK. The airborne differential optical absorption spectroscopy (DOAS measurements provided an unprecedented level of spatial resolution, over 2 orders of magnitude greater than satellite observations and with vertical resolution unable to be achieved by satellite methods, for BrO in the Arctic. This novel method provided quantitative identification of a BrO plume, between 500 m and 1 km aloft, moving at the speed of the air mass. Concurrent aerosol particle measurements suggest that this lofted reactive bromine plume was transported and maintained at elevated levels through heterogeneous reactions on colocated supermicron aerosol particles, independent of surface snowpack bromine chemistry. This chemical transport mechanism explains the large spatial extents often observed for reactive bromine chemistry, which impacts atmospheric composition and pollutant fate across the Arctic region, beyond areas of initial snowpack halogen production. The possibility of BrO enhancements disconnected from the surface potentially contributes to sustaining BrO in the free troposphere and must also be considered in the interpretation of satellite BrO column observations, particularly in the context of the rapidly changing Arctic sea ice and snowpack.

    2016-01-01

    The purpose of this study is to elicit insight from the public policy leaders of 2 regional professional nursing organizations on key qualities of their current advocacy initiatives that motivate nurses to sustain momentum in public policy advocacy beyond a single episode. The goal is to inform quality improvement in the development of future advocacy initiatives to increase sustained engagement of nurses. Social cognitive theory was used as the rationale for this qualitative, descriptive study. A purposive convenience sample of executive leadership and board committee members from 2 regional professional nursing organizations were recruited to complete an initial Web-based electronic survey, followed by separate semistructured interview focus groups. One organization was composed primarily of advanced practice registered nurses, and the other group composed of diverse, multispecialty nursing members with varied educational levels. Nine themes emerged, categorized as facilitators or challenges to the positive impact of advocacy initiatives on nurses' motivation. Highlighting and marketing facilitators to the positive impact of advocacy initiatives on nurses' motivation to sustain momentum in public policy advocacy, while designing and testing new initiatives that address the challenges, may increase the number of nurses who sustain engagement in the policy advocacy process.

  12. Nitrogen implantation of steels: A treatment which can initiate sustained oxidative wear

    International Nuclear Information System (INIS)

    Hale, E.B.; Reinbold, R.; Missouri Univ., Rolla; Kohser, R.A.

    1987-01-01

    Falex wear tests on mild (SAE 3135) steel samples treated by either nitrogen implantation (2.5x10 17 N 2 + cm -2 at 180 keV) or low temperature (about 315 0 C) oxidation are reported. The results show that both treatments lead to about an order-of-magnitude reduction in the long-term wear rate of the steel. In addition to the wear rate measurements, the wear member asymmetry behavior, scanning electron microscopy studies, Auger spectra and sputter profiles all indicate that the wear modes induced by both treatments are the same and are oxidative wear. These results confirm the previously proposed initiator-sustainer wear model in which implanted nitrogen simply acts as an initiator of favorable oxidative wear but is not directly involved in maintaining the sustained wear resistance. Possible mechanisms for both the initiation process and the sustained wear process are reviewed and discussed. (orig.)

    2017-11-01

    Full Text Available This paper addresses a coordination problem of production and green transportation and the effects of production and transportation coordination on supply chain sustainability in a global supply chain environment with the consideration of important realistic characteristics, including parallel machines, different order processing complexities, fixed delivery departure times, green transportation and multiple transportation modes. We formulate the measurements for carbon emissions of different transportation modes, including air, sea and land transportation. A hybrid genetic algorithm-based optimization approach is developed to handle this problem, in which a hybrid genetic algorithm and heuristic procedures are combined. The effectiveness of the proposed approach is validated by means of various problem instances. We observe that the coordination of production and green transportation has a large effect on the overall supply chain sustainability, which can reduce the total supply chain cost by 9.60% to 21.90%.

    2014-01-01

    Full Text Available City logistics is a field that attracts increasing attention of professionals and scientific community and international organizations. Research on problems of urban areas' logistics gives different results and practical solutions. City logistics flows are characterized by partiality, spatial dispersion of generators, diversity in terms of the logistics chains structure, frequency of a large number of smaller shipments, dynamism, stochasticity etc. Problems and the complexity of logistics in urban areas as well as significant decline in the quality of life in modern cities have caused the development of initiatives and concepts of city logistics which should allow the sustainable development of urban areas. The first part of this paper presents the problems of city logistics and impact of logistics activities on urban areas in terms of economic, environmental and social sustainability. The second part presents city logistics initiatives that involve the change of urban area context, in order to improve its sustainability.

    2013-01-01

    There is a growing consensus that within two decades initial human missions to Mars are affordable under plausible budget assumptions and with sustained international participation. In response to this idea, a distinguished group of experts from the Mars exploration stakeholder communities attended the "Affording Mars" workshop at George Washington University in December, 2013. Participants reviewed and discussed scenarios for affordable and sustainable human and robotic exploration of Mars, the role of the International Space Station over the coming decade as the essential early step toward humans to Mars, possible "bridge" missions in the 2020s, key capabilities required for affordable initial missions, international partnerships, and a usable definition of affordability and sustainability. We report here the findings, observations, and recommendations that were agreed to at that workshop.

    The aim of this study was to provide evidence about the design and implementation of policies for advancing the sustainability of knowledge translation (KT) initiatives and policies in Uganda's health system. We searched for and reviewed evidence about KT sustainability issues in Uganda, the impacts of options, barriers to implementing these options, and implementation strategies to address such barriers. In instances where the systematic reviews provided limited evidence, these were supplemented with relevant primary studies. Documents such as the government reports and unpublished literature were also included in the search. Key informant interviews and a policy dialogue were conducted, and an expert working group guided the study. The KT sustainability issues identified were: the absence of a specific unit within the health sector to coordinate and synthesize research; health worker not familiar with KT activities and not often used. Furthermore, Uganda lacks a mechanism to sustain its current national health frameworks or platforms, and does not have a system to ensure the sustained coordination of existing national health KT platforms. The policy options proposed include: (i) the identification of a KT champion; (ii) the establishment of an operational KT framework; (iii) KT capacity building for researchers and research users, as well as policy and decision makers. The sustainability of KT will be influenced by the prevailing context and concerns within healthcare both in Uganda and internationally. Furthermore, the availability of resources for KT advocacy, communication, and program design will impact on the sustainability of Uganda's KT activities.

    Urban sustainability certification (USC) systems comprehensively assess and benchmark the sustainability of neighborhoods, communities, etc. However, it is important to understand what USCs mean by neighborhoods and communities in terms of definition and their certified developments' size. This study focuses on sustainable transportation and its measures in USCs in order to discern: how relevant are these measures to the varied local conditions, especially in developing countries? And whether they can generate palpable benefits vis-à-vis the certified developments' site areas. Taking descriptive analysis methods, this study focuses on four prominent USCs, namely, LEED for Neighborhood Development, BREEAM Communities, CASBEE for Urban Development, and The Pearl Community Rating System. The four USCs prescribed multiple measures for sustainable transportation, particularly in favor of active transportation and public transportation. However, the relatively small size of their citified developments and the varying transportation conditions among different contexts attenuate the viability and relevance of the advocated measures for both modes. In order to yield more benefits, USCs should underscore the integrative nature of neighborhoods and communities, and transportation within their prescribed criteria and measures. Moreover, sustainable transportation as a theme should be tailored to the local conditions rather than being adopted or adapted from global USCs. - Highlights: • Transportation measures in four prominent certification systems were investigated. • Most certified neighborhoods, communities and developments have small site areas. • Certifications are insensitive to realities of transport in developing countries. • Benefits from advocating active transport only within certified areas are minimal. • Certifications devalue the integrative nature of neighborhoods and transportation.

    The active participation in Community Based Initiatives (CBI) is a spreading phenomenon that has reached a significant magnitude and - in some cases - CBIs are also supposed to have catalysed social and technological innovation, thus contributing to global transition into low-carbon economy. Generally speaking, CBIs are grassroots initiatives with broad sustainability foci that promote a plethora of activities such as alternative transportation, urban gardening, renewable energy implementation, waste regeneration/reduction, etc. Some advocate that such practices fostered by bottom-up activities, rather than top-down policies, represent a proficient countermeasure to alleviate global environmental change and effectively foster a societal transition towards sustainability. However, thus far most empirical research grounds mainly on anecdotal evidence and little work has been done to quantitatively assess CBIs' "environmental impacts" (EI) or their carbon footprints using comparative methodologies. This research main aim is to frame a methodology to assess univocally CBIs' EIs which are crucial to understanding their role in societal sustainability transition. However, to do so, three main caveats need to be addressed: first, some CBIs do not directly produce tangible measurable outputs, nor have an intelligibly defined set of inputs (e.g. CBIs focusing on environmental education and awareness rising). Thus, calculating their "indirect" EI may represent an intricate puzzle that is very much open to subjective interpretation. Second, CBIs' practices are heterogenic and therefore existing methodologies to make comparisons of their EIs are neither straightforward nor proficient, also given the lack of available data. Third, another issue closely related to the one previously mentioned, is a general lack of consensus among already existing impact-assessment frameworks for certain practices (e.g. composting). A potential way of estimating a CBI's EI is a standard Carbon

    Full Text Available Due to the rapid deregulation of freight transport in South Africa two decades ago, and low historical investment in rail (with resultant poor service delivery, an integrated alternative to road and rail competition was never developed. High national freight logistics costs, significant road infrastructure challenges and environmental impact concerns of a road-dominated freight transport market have, however, fuelled renewed interest in intermodal transport solutions. In this article, a high-level business case for domestic intermodal solutions in South Africa is presented. The results demonstrate that building three intermodal terminals to connect the three major industrial hubs (i.e. Gauteng, Durban and Cape Town through an intermodal solution could reduce transport costs (including externalities for the identified 11.5 million tons of intermodalfriendly freight flows on the Cape and Natal corridors by 42% (including externalities.

    In the twenty-first century the sustainability of energy and transportation systems is on the top of the political agenda in many countries around the world and governments are establishing policies towards a sustainable, low emissions energy future. Environmental impacts of human economic activity necessitate the consideration of conflicting goals in decision making processes to develop sustainable systems. Any sustainable development has to reconcile conflicting economic and environmental objectives and criteria. The science of multiple criteria decision making has a lot to offer in addressing this need. Decision making with multiple (conflicting) criteria is the topic of research that is at the heart of the International Society of Multiple Criteria Decision Making. This book is based on selected papers presented at the societies 19th International Conference, held at The University of Auckland, New Zealand, from 7th to 12th January 2008 under the theme ''MCDM for Sustainable Energy and Transportation Systems''.

  1. Envisioning Parking Strategies in the Framework of Sustainable Urban Transport

    Directory of Open Access Journals (Sweden)

    Giovanni Circella

    2009-05-01

    Full Text Available Monetary instruments to regulate parking are often used in central areas of cities to discourage long term parking of vehicles. The availability of parking facilities, and its cost, in fact represents an important element in the decision to operate private vehicles in urban areas. The availability of instruments and tools to check the outcome of modification in parking regulations, in terms of modification of car use, successfully support planners in the determination of the best policies to decrease congestion, and regulate the use of transportation in cities. Integrated land use transportation models may successfully contribute to the assessment of such policy packages. This contribution discusses the use of the model MARS-Bari (Metropolitan Activity Relocation Simulator for the analysis of future scenarios of development of land use and transportation. MARS-Bari is a fast integrated land use transportation model, which is designed for applications in strategic planning of urban and metropolitan areas. The model was developed as a decision support tool, to help planners in the definition of sets of policies on land use and transportation, and promote equilibrated growth of the urban system (smart growth. MARS-Bari shares the basic assumptions of the Metropolitan Activity Relocation Simulator (MARS modeling system, so far successfully applied to many cities of both Europe and Asia. The structure of MARS-Bari is highly flexible on purpose, allowing multiple hypothesis tests of future scenarios and policies. MARS-Bari works at a high level of spatial aggregation, and its simulations are developed on a long-term time horizon (30-years in the current version. Two main sub-models run in MARS-Bari: they respectively simulate the development of land use, and the transportation system. Four different classes of users are distinguished in the transportation model, depending on the possible access to one or more of the five transportation modes: car

    The setting for this quality improvement initiative designed to reduce the prevalence of facility-acquired heel pressure ulcers was a regional, acute-care, 490-bed facility in Ontario, Canada, responsible for dialysis, vascular, and orthopedic surgery. An interdisciplinary skin and wound care team designed an evidence-based quality improvement initiative based on a systematic literature review and standardization of heel offloading methods. The prevalence of heel pressure ulcers was measured at baseline (immediately prior to implementation of initiative) and at 1 and 4 years following implementation. The prevalence of facility-acquired heel pressure ulcers was 5.8% when measured before project implementation. It was 4.2% at 1 year following implementation and 1.6% when measured at the end of the 4-year initiative. Outcomes demonstrate that the initiative resulted in a continuous and sustained reduction in facility-acquired heel pressure ulcer incidence over a 4-year period.

    Full Text Available Sustainable seafood labeling programs have been developed as one of several efforts to address the current dire trends in fish stocks. The Ocean Wise (OW program, started at the Vancouver Aquarium (Canada, works with restaurateurs and suppliers to simplify sustainable purchasing decisions. By aiding restaurateurs with responsible purchasing, OW hopes to shift demand to sustainable seafood products. OW has grown in numbers and spread across Canada quickly; we examine the factors associated with individual and organizational decisions to participate in the program, including personal, business, and program-related factors. These factors were examined in relation to OW membership by Vancouver restaurateurs. Results show that restaurateurs with greater knowledge of seafood issues and restaurants with greater commitment to a range of green initiatives are more likely to participate in the OW program. By focusing efforts on education and incorporating a range of green values into marketing, OW can maximize their limited resources to grow membership.

    The sustainability of successful public health programmes remains a challenge in low and middle income settings. These programmes are often subjected to mobilization-demobilization cycle. Indeed, political and organizational factors are of major importance to ensure this sustainability. The cooperation between the World Bank and the Brazilian AIDS programme highlights the role of international institutions and global health initiatives (GHI), not only to scale up programmes but also to guarantee their stability and sustainability, at a time when advocacy is diminishing and vertical programmes are integrated within health systems. This role is critical at the local level, particularly when economic crisis may hamper the future of public health programmes. Political and organizational evolution should be monitored and warnings should trigger interventions of GHI before the decline of these programmes.

    This study attempts to characterize national passenger and freight transportation sustainability. Based on the indicator that measures the conformity of the growths of all sectors with transportation, the Islamic countries are comparatively studied. The proposed measure, elasticity for each pair of variables indicates the extent to which the two variables have been changing consistently. The study database consisted of key aspects of transportation sustainability in the form of national variables including transportation, economic, social and environmental categories for the period 1980-1995. Firstly, the elasticity of social, environmental and economic variables with respect to passenger and freight transportation variables was developed. Using individual elasticities, composite passengers and freight sustainability indices were suggested. Then, utilizing partial order theory and Hasse Diagram Technique (HDT), two composite indices were employed to visualize the comparative situation of the countries. Based on comparative appraisal achieved by HDT, country ranking were developed. The methodology may be applied to any other time and geographic area for addressing pertinent issues for balancing and sustainable development of transportation systems. (author)

    2016-09-01

    Full Text Available While digitalization opens up new possibilities for cultural heritage and tourism it also brings new challenges. Initiatives such as “Europeana”, an internet portal for cultural heritage within the European Union, support institutions with the display of their collections. National initiatives complement these efforts. This report describes initiatives and projects for generating and sustaining digital cultural heritage resources in the German state of Brandenburg. With the cultural heritage distributed throughout the state and managed by hundreds of institutions, the task of digitalization is a common challenge for all of these institutions. Digitalization and digital sustainability is limited by shortcomings in areas of human resources, knowledge and IT infrastructure. In light of these limitations, the cultural heritage community addresses challenges with an interdisciplinary approach. It is based on a collaborative model with four levels: (1 a statewide strategy of an interdisciplinary task force; (2 cooperative projects; (3 cooperative IT infrastructure; and (4 an overall coordination. The priorities are: (1 creating and displaying digital content; (2 establishing best practices and workflows; (3 developing cooperative infrastructures for sustainment. Since 2012, several projects have been implemented based on that collaborative model. More than 50 participating institutions benefited from cooperative planning, managing, digitizing and digital presentation. With regard to the third priority, the task force’s next step is finding solutions for digital preservation. Considering the lack of funding and resources in the cultural heritage sector, options for creating and sustaining digital resources are limited. Digital cultural heritage requires interdisciplinary thinking, cooperative initiatives, reliable IT infrastructures and additional funding.

    Directory of Open Access Journals (Sweden)

    Liyin Shen

    2018-03-01

    Full Text Available With the rapid development of emerging cities in China, policy makers are faced with the challenges involved in devising strategies for providing transportation systems to keep pace with development. These challenges are associated with the interactive effects among a number of sophisticated factors involved in transportation systems. This paper presents a system dynamics simulation approach to analyze and select transportation development strategies in order to achieve good sustainability performance once they are implemented. The simulation approach consists of three modules: a socio-economic module, a demand module, and a supply module. The approach is validated through applying empirical data collected from the Shenzhen statistical bulletins. Three types of transport development strategies are selected for the city and examined for their applicability and effects through simulation. The strategies are helpful for reducing decision-making mistakes and achieving the goal of sustainable urban development in most emerging cities.

    The reduction of the number of retail shops, in principle, provide for better planning opportunities regarding the distribution of commodities to the shops. But this, according to the study is more than offset by the longer distances the goods have to travel before reaching the shops. The report investigates the potentials for reduction of the energy demand and emission by means of technical improvements of vehicles. The assessments are based on fuel cycle considerations covering both the energy system (that is, the system providing the fuel to the vehicle) and the vehicle system (the system on board the vehicle transforming the fuel to useful work). In general, there are substantial potentials for improvements of the energy efficiency of the transportation means - and even greater potentials for CO{sub 2}-reductions. The reap the full potentials, it is probably necessary to break with the present technological development trend. (au) 274 refs.

    2009-11-01

    This paper offers the description of an integrated information system framework for the assessment of transportation planning and management. After an introductory exposition, in the first part of the paper, a broad overview of international experiences regarding information systems on transportation is given, focusing in particular on the relationship between transportation system's performance monitoring and the decision-making process, and on the importance of this connection in the evaluation and planning process, in Italian and European cases. Next, the methodological design of an information system to support efficient and sustainable transportation planning and management aiming to integrate inputs from several different data sources is presented. The resulting framework deploys modular and integrated databases which include data stemming from different national or regional data banks and which integrate information belonging to different transportation fields. For this reason, it allows public administrations to account for many strategic elements that influence their decisions regarding transportation, both from a systemic and infrastructural point of view.

The objective of this article is to analyse how the international scientific production addresses sustainable practices and initiatives and their relationship with organizational performance. Considering this scope, a bibliometric study of the publications located on Web of Science - Social Sciences Citation Index (WoS-SSCI was developed. There were 33 articles identified and selected on the subject. Journals that stand out in quantity of articles and number of citations are the Journal of Cleaner Production and Strategic Management Journal, respectively. Analysing the results, a growing concern about this issue and the increase in publications was noticed after the 2000s. The results found, in general, associate sustainable practices to positive organizational performance, such as increased profit on the product sold, quality improvement, improved reputation, and waste reduction, among others gains identified.

    To stimulate the commercial space transportation industry, the National Aeronautics and Space Administration (NASA) is facilitating the demonstration of Commercial Orbital Transportation Services (COTS) to Low Earth Orbit (LEO) by private-sector companies. In 2006, NASA entered into funded agreements with two such companies to share NASA's 500 million investment, Space Exploration Technologies (SpaceX) and Rocketplane Kistler (RpK), each of which proposed to obtain the additional private financing needed to complete its flight demonstrations. In 2007, NASA terminated the agreement with RpK because it failed to meet a series of technical and financial milestones which were necessary to receive the incremental NASA payments. In 2008, NASA conducted another competition for the remaining 170 million of NASA funding and entered into a funded agreement with Orbital Sciences Corporation (OSC). This paper provides an overview of the COTS approach of SpaceX and OSC and the status of their efforts to develop reliable and cost-effective commercial transportation to serve the LEO marketplace.

  5. Efficiency and sufficiency. Towards sustainable energy and transport

    International Nuclear Information System (INIS)

    Bleijenberg, A.N.; Van Swigchem, J.

    1997-03-01

    A crucial question today is whether the development of clean technology can reduce environmental pollution to an acceptable level, or whether the growth of polluting activities must be stemmed as a complementary measure. This is the key issue addressed in the title discussion paper, which focuses specifically on the CO2 emissions of the energy and transport sectors. A systems analysis of these two sectors shows that the required improvements in efficiency can only be achieved - through technological improvements - if there is also slightly less growth in polluting activities. The underlying reason is that improvements in technological efficiency also lead to a drop in the price of polluting activities, leading in turn to an increase in demand. Only by means of strong government policy can an absolute reduction in CO2 emissions be achieved, thus countering this negative feedback. Effective policy to this end inevitably leads to extra costs and/or to lower growth in comfort enhancement. This is the price tag associated with abatement of CO2 emissions. 29 refs

    Promoting physical activity and sustainable transportation is essential in the face of rising health care costs, obesity rates, and other public health threats resulting from lack of physical activity. Targeted communications can encourage distinct population segments to adopt active and sustainable transportation modes. Our work is designed to promote the health, social, and environmental benefits of sustainable/active transportation (ST) using the Transtheoretical Model of Change (TTM), which has been successfully applied to a range of health, and more recently, sustainability behaviors. Earlier, measurement development confirmed both the structure of ST pros and cons and efficacy measures as well as the relationship between these constructs and ST stages of change, replicating results found for many other behaviors. The present paper discusses a brief pre-post video pilot intervention study designed for precontemplators and contemplators (N = 604) that was well received, effective in moving respondents towards increased readiness for ST behavior change, and improving some ST attitudes, significantly reducing the cons of ST. This research program shows that a brief stage-targeted behavior change video can increase readiness and reduce the cons for healthy transportation choices. PMID:29346314

  10. Energy equity: will the UN Sustainable Energy For All initiative make a difference

    2012-05-15

    Access to affordable modern energy services may not be a Millennium Development Goal (MDG) but without it, sustainable development, indeed the MDGs themselves, cannot be achieved. Yet energy access remains an area of great global inequity. On one hand, wealthy countries and communities consume vast amounts of often subsidised energy resources every day. On the other hand, 1-in-5 people lives with no access to grid electricity, and around 40 per cent of the world's population (nearly three billion people) lack the technologies to make cooking fuels clean, safe and efficient. Can the UN's Sustainable Energy for All initiative in 2012 redress the balance? Perhaps, but only if it puts improving the lives of the poorest and most vulnerable at the heart of its efforts.

  11. Enacting Sustainable School-Based Health Initiatives: A Communication-Centered Approach to Policy and Practice

    Science.gov (United States)

    Canary, Heather E.

    2011-01-01

    Communication plays an important role in all aspects of the development and use of policy. We present a communication-centered perspective on the processes of enacting public health policies. Our proposed conceptual framework comprises 4 communication frames: orientation, amplification, implementation, and integration. Empirical examples from 2 longitudinal studies of school-based health policies show how each frame includes different communication processes that enable sustainable public health policy practices in school-based health initiatives. These 4 frames provide unique insight into the capacity of school-based public health policy to engage youths, parents, and a broader community of stakeholders. Communication is often included as an element of health policy; however, our framework demonstrates the importance of communication as a pivotal resource in sustaining changes in public health practices.

    Transportation industry is rapidly developing owing to its size and importance which affects on various aspects of life. It includes all the transport means that facilitate mobility of people or goods either by air, land or sea like aircrafts, automotives, ships, trains, etc. The utilization of textiles in this industry is increasing as a result of moving towards achieving sustainability and enhancing performance, comfort and safety. Through substituting heavier materials with textiles of high performance specifications and textile reinforced composites to reduce weight, fuel consumption and CO2 emissions. Composite materials can fulfil the demands for sustainability in the transportation sector through using renewable, recycled and lightweight materials, considering the requirements of each category of transport vehicles. Textiles used in reinforcing composites are diverse including fibers, yarns or fabric preforms such as woven, nonwoven, knitted, braided which varies from 2D to complex 3D structures. This paper presents a brief review on the utilization of textiles in reinforcing composites for various transportation applications to achieve sustainability. Also, discussing the influence of textiles structural parameters like fiber material properties, fabric production technique and construction on their mechanical behaviour. Focusing on researches findings in this area and highlighting some prospects for further developments domestically.

    This collaborative educational project between the University of Michigan—Ann Arbor, University of Michigan—Dearborn and the Kettering University successfully executed almost all the elements we proposed to do. In the original proposal, we proposed to develop four graduate courses, six undergraduate courses, four professional short courses, a K-12 electric vehicle education kit, a Saturday morning seminar series, and a set of consumer education material to support the advancement of transportation electrification. The first four deliverables were all successfully developed and offered. When we held the kick-off meeting in NETL in Morgantown back in early 2010 with all the ten ARRA education teams, however, it quickly became clear that among the ten ARRA education grantee teams, our proposed “consume education” activities are not better or with the potential to create bigger impact than some of activities proposed in other teams. For example, the Odyssey 2010 event held by the West Virginia University team had planned and successfully reached to more than 230,000 attendees, which is way more than what our proposed 100k event could ever reach. It was under the suggestion of Joseph Quaranta, the ARRA education Program Director at that time, that we should coordinate and eliminate redundancy. The resources should then be focused on activities that have less overlap. Therefore, the originally proposed activities: Saturday morning seminar series, and a set of consumer education material were dropped from our scope. We expanded the scope of our “education kit” activity to include some educational materials, mainly in the form of videos. The target audience also changed from general public to K-12 students. The majority of the project cost (~70%) goes toward the establishment of three undergraduate laboratories, which provides critically needed hands-on learning experience for next-generation green mobility engineers. We are very proud that the ARRA money

    Wonju is the first municipality in the Republic of Korea to fund the Healthy City project through municipal revenues from the local tobacco consumption tax. We investigated the process of the local tobacco consumption tax being approved as the main source of financing for the local Healthy City project. We also examined the sustainability and sufficiency of the funding by looking at the pricing policies instituted for cigarettes, smoking prevalence, cigarette consumption and revenues from local tobacco consumption as well as the budgetary allocations among programs in the city. The strong initiative of the mayor of Wonju was one of the factors that enabled the earmarking of the local tobacco consumption tax for the Healthy City Wonju project. He consulted academic counselors and persuaded the municipal government and the City Council to approve the bill. Despite the increasing price of cigarettes in Korea, adequate funding can be sustained to cover the short-term and mid-term programs in Wonju for at least 5 years of the mayor's term, because the smoking rate is persistently high. Analyzing the effects of strong leadership on the part of local authorities and the balance between revenues from the tobacco tax and the prevalence of smoking in the face of anti-smoking policies would be helpful for other countries and communities interested in developing sustainable Healthy Cities projects.

    2016-03-01

    Full Text Available This paper explores whether and to what extent wind discourages sustainable transportation mode choice, which includes riding public transportation, bicycling, and walking. A six month-long field study was carried out at four locations in San Francisco, a city that has been promoting sustainable transportation mode choice but that experiences high wind levels. It involved surveying pedestrians and on-site recording of microclimate data using various instruments. The survey adopted a mixed-method approach to collect both quantitative and qualitative data. Statistical analyses using Kruskal Wallis tests and ordinal logistic regression models identified the significant effect of wind speed on San Francisco’s residents in estimating their discouragement for waiting at transit stop without shelter, bicycling, and walking. Qualitative data revealed a deeper understanding of how wind influences their sustainable transportation mode choice. This research argues for the need to adopt climate-based efforts in urban planning and policy and sheds light on the climate resilience of cities

  6. Analysis on Transportation Infrastructure Availability to Achieve Environmental and Social Sustainability in Karawang

    Rarasati, A. D.; Octoria, N. B.

    2018-03-01

    Sustainable infrastructure is the key to development success. At the same time, transportation infrastructure development will involve social and environmental conditions of the local surroundings. Assessment of the availability of such transport infrastructure is one of the solutions adapted from social and environmental impacts. By conducting a correlation test, the presence of transportation infrastructure and the social conditions of the environment can be identified. The results obtained show that the accessibility, the level of security, and the level of equality are correlated to social and environmental sustainability in Karawang. In terms of environment, the availability of transportation infrastructure is not directly related to the impact of environmental sustainability. The impact of the perceived environment also has no effect on the journey. Correlation results indicate that the length of travel time and congestion level do not make the perceived impact greater. The impact of the perceived environment is merely due to the high utilization of private vehicles in Karawang which subsequently leads to higher energy consumption.

    2015-01-01

    Full Text Available Despite climate change mitigation and sustainability agendas, road transport systems in Germany and the resulting environmental burden are growing. Road transport is a significant source of emissions in urban areas and the infrastructure has a significant impact on the urban form. Nevertheless, mobility is a fundamental requirement for the satisfaction of the human desire to socially and economically engage in society. Considering these realities and the desire for sustainable development in a growing city (Potsdam, Germany, an integrated assessment methodology was co-developed among scientists and practitioners to prioritize a suite of transport-related measures. The methodology reflects the city’s qualitative and quantitative goals to improve public transport and promote sustainability, capturing synergies in categories that include environmental considerations as well as road safety, eco-mobility, and quality of life. This approach applies a multi-criteria analysis (MCA to derive a practically relevant solution for the local traffic and mobility problems that fosters ownership and accountability of all involved. This paper reflects on the process of developing the MCA, and the different aspects that were found important and required consideration during the process. Recommendations on specific traffic-related measures and the assessment of their effectiveness are not given. The aim is that such process information could foster greater collaboration within city departments and similar transdisciplinary efforts.

  9. Urban Mobility Analysis on Efficiency and Sustainability by Means of Transportation

    Science.gov (United States)

    Branea, Ana-Maria; Gaman, Marius; Badescu, Stefana

    2017-10-01

    Patterns of urban land use are inherently linked to the predominantly used means of transportation, both generating and being generated themselves. While each mode of transportation shapes a different development typology a clear understanding of their interrelations and dependencies is needed in order to create a comprehensive mobility strategy. The study proposes a 15-criteria analysis framework developed to identify and quantify the main modes of transportation’s key aspects. The analysis framework was applied to a yearlong research on Timisoara, Romania, comprising hard, quantitative data, digital simulations and mobility pattern analysis and soft data, quality assessment and perceived needs and satisfaction levels. The research was carried out in clear opposition to the national trend of official mobility strategies focusing on accommodating increased levels of car traffic on the underdeveloped existing roads infrastructure. By analysing the efficiency and sustainability of all four main modes of transportation the results offer a holistic comprehensive view. While, despite current practices, no mobility strategy can focus on a single means of transportation, the article will only present in detail the research on cycling, infrastructure and use, as it is the most underdeveloped and least discussed at the national level and proven through our study to be the most efficient for a city of Timisoara’s size and characteristics. By identifying a clear link between urban land use patterns, infrastructure quality and perceptions and the most efficient means of transportation for each particular city type mobility strategies could shift the trend of urban development towards a more sustainable one.

    Rukmana, D.

    2018-03-01

    Not only is Jakarta the largest metropolitan area in Southeast Asia, it is the also one of the most dynamic, though beset with most of the urban problems experienced in twenty-first century Southeast Asia. Batavia, colonial capital of the Netherland Indies in the first half of the 20th century was a small urban area of approximately 150,000 residents. In the second half, Batavia became Jakarta, the 28 million megacity capital of independent Indonesia. Among many urban problems, one major problem plagued Jakarta in the last two decades is traffic congestions. This paper discusses the extent to which rapid urbanization in Jakarta has contributed to the need for sustainable transportation policies in Jakarta. The development of MRT could be viable solutions to alleviate the acute traffic jams in Jakarta. Jakarta will need to implement other innovative sustainable transportation policies including promoting active live through more walking and bicycling, carpool matching services, shuttle services, telecommuting and downzoning in downtown areas.

    Recently, the use of attitude-based market segmentation to promote environmentally sustainable transport has significantly increased. The segmentation of the population into meaningful groups sharing similar attitudes and preferences provides valuable information about how green measures should...... and behavioural segmentations are compared regarding marketing criteria. Although none of the different approaches can claim absolute superiority, attitudinal approaches show advantages in providing startingpoints for interventions to reduce car use....

  18. Resource Allocation for Sustainable Urban Transit from a Transport Diversity Perspective

    Directory of Open Access Journals (Sweden)

    Cheng-Min Feng

    2009-11-01

    Full Text Available Different transport stakeholders have different needs for transport infrastructure and services. Meeting the needs of all stakeholders implies a trade-off of benefits and costs between supply and demand and creates transport diversity issues. However, the literature has largely ignored these issues. Transport diversity can assess the level to which important needs are satisfied equitably, and monitor whether transportation systems are moving towards sustainability by confirming the targets and basic level of quality of life. Based on the concept of transport diversity, this study utilizes fuzzy multi-objective programming to solve non-linear multi-objective problems involving urban public transit systems to determine the impact of resource allocation on needs satisfaction in relation to stakeholder behaviors. The proposed approach avoids problems of inefficient and inequitable resource allocation. A real-life case is presented to demonstrate the feasibility of applying the proposed methodology. Furthermore, empirical outcomes show that recent investments allocated to public transit systems considered equitable stakeholder satisfaction for both mass rapid transit (MRT and bus, and also promoted transport diversity in the Taipei metropolitan area.

  19. Sustaining reductions in postoperative nausea and vomiting after evidence-based practice initiative: A success story

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available Background: Postoperative nausea and vomiting (PONV remains a signifi cant problem in the surgical population. Many researchers have demonstrated signifi cant reductions in institutional PONV when risk screening and antiemetic prophylaxis protocols are implemented. These protocols have not been universally adopted. Our adoption and implementation led to signifi cant reductions in PONV. The challenge is to sustain these reductions over time. Methods: A retrospective cohort chart review of consecutive surgical patients (n = 1002 during the period encompassing October through November of 2016, the sustainability group (G16. Descriptive statistics were used to compare G16 with the implementation group (G14 in regard to demographic data, and Z-score and Chi-square (χ2 statistics were utilized to determine levels of signifi cance. Correlations were calculated to determine levels of compliance to the protocol and the incidence of PONV. Results: A significant (P = 0.0007 reduction in PONV incidence was identified as 8.5% (85/1002 in G16 compared to 13.4% (134/997 achieved in G14. Overall compliance with the targeted prophylaxis protocol was 87.2% (G16, 874/1002, a significant (P = 0.0001 improvement compared to 79% (G14, 788/997. A 61.1% (11/18 incidence of PONV in laparoscopic gastric bypass patients was identifi ed in the G16 group. Conclusions: Initial reductions in PONV were not only sustained but significantly improved. Preoperative risk assessment for PONV, risk stratification, and fidelity to anti-emetic prophylaxis protocols reduce the incidence of PONV in the post-anesthesia care unit. High-risk patients require three or more interventions to obtain acceptable reductions in PONV. Laparoscopic gastric bypass patients remain a high-risk group requiring aggressive multimodal prophylaxis beyond their Apfel simplifi ed risk score.

    Beginning in early 2011, the Centers for Disease Control and Prevention and the Association of Public Health Laboratories launched the Laboratory Efficiencies Initiative (LEI) to help public health laboratories (PHLs) and the nation's entire PHL system achieve and maintain sustainability to continue to conduct vital services in the face of unprecedented financial and other pressures. The LEI focuses on stimulating substantial gains in laboratories' operating efficiency and cost efficiency through the adoption of proven and promising management practices. In its first year, the LEI generated a strategic plan and a number of resources that PHL directors can use toward achieving LEI goals. Additionally, the first year saw the formation of a dynamic community of practitioners committed to implementing the LEI strategic plan in coordination with state and local public health executives, program officials, foundations, and other key partners.

    Arbon, M; Ireland, M

    2003-01-01

    Melbourne Water has adopted a challenging target of recycling 20 per cent of treated effluent from Melbourne's two major sewerage treatment plants by 2010. This target was adopted in response to key drivers for water recycling in the Melbourne region such as: strong support for conserving water resources and protecting marine environments; acknowledgment of recycled water as a valuable resource; greater emphasis on environmental issues and sustainable management principles; and opportunities to increase demand for recycled water through effective planning mechanisms. Issues that must be effectively addressed to meet the target include: managing public perceptions of recycled water; health and environmental concerns; lack of consensus among government agencies; high up-front costs of infrastructure; and prices of other sources of water supply not currently true costed. Melbourne Water has identified the following factors as critical in determining the success of recycling strategy: ability to demonstrate that water recycling will be important in terms of long term water cycle management; effective stakeholder consultation; gaining government support; establishing long-term, guaranteed markets for recycled water; implementing well planned, large scale recycling schemes; ability to provide a product that meets customer needs; regulatory approval; and implementation of a system that is economically viable. Water recycling initiatives are being investigated on household, local and regional levels. Over 10 proposals that will contribute to the 20 per cent recycled water target from the regional treatment plants are under various stages of development. Melbourne Water's commitment to recycling within a total water cycle management context is a vital component of this major new initiative for Melbourne and is crucial for a sustainable future.

  3. How much transport can the climate stand?-Sweden on a sustainable path in 2050

    International Nuclear Information System (INIS)

    Akerman, Jonas; Hoejer, Mattias

    2006-01-01

    In this paper an image of a sustainable transport system for Sweden in 2050 is outlined. The emissions per capita in this image may be generalized to a global population of 9 billions, and still be consistent with a stabilization of the carbon dioxide concentration at 450 ppm (parts per million). Swedish transport energy use per capita is 4.6 MWh in the image, compared to 12.5 MWh at present. The aim is, first, to widen the perspective of sustainable transport futures and, second, to provide a basis for present decisions in areas characterized by a high inertia, e.g. regarding infrastructure and the built-up environment. All transport generated by the lifestyles of Swedish residents are included. The reduction of energy use in the image is primarily achieved by an introduction of energy efficient vehicles and a conscious combination of IT-services and urban planning. The latter aims at increasing functional accessibility while reducing commuting. A prioritization of leisure travel to structurally-enforced travel gives the possibility to increase leisure travel per capita by one third. However, this is contingent on a 50% reduction of per capita car travel in cities. Given the set-up target, it may be concluded that the need for new arterial road capacity in cities often is negligible, even with a considerable population increase

  4. On the initiation of sustained slip-weakening ruptures by localized stresses

    KAUST Repository

    Galis, Martin

    2014-12-10

    Numerical simulations of dynamic earthquake rupture require an artificial initiation procedure, if they are not integrated in long-term earthquake cycle simulations. A widely applied procedure involves an \\'overstressed asperity\\', a localized region stressed beyond the static frictional strength. The physical properties of the asperity (size, shape and overstress) may significantly impact rupture propagation. In particular, to induce a sustained rupture the asperity size needs to exceed a critical value. Although criteria for estimating the critical nucleation size under linear slip-weakening friction have been proposed for 2-D and 3-D problems based on simplifying assumptions, they do not provide general rules for designing 3-D numerical simulations. We conduct a parametric study to estimate parameters of the asperity that minimize numerical artefacts (e.g. changes of rupture shape and speed, artificial supershear transition, higher slip-rate amplitudes). We examine the critical size of square, circular and elliptical asperities as a function of asperity overstress and background (off-asperity) stress. For a given overstress, we find that asperity area controls rupture initiation while asperity shape is of lesser importance. The critical area obtained from our numerical results contrasts with published theoretical estimates when background stress is low. Therefore, we derive two new theoretical estimates of the critical size under low background stress while also accounting for overstress. Our numerical results suggest that setting the asperity overstress and area close to their critical values eliminates strong numerical artefacts even when the overstress is large. We also find that properly chosen asperity size or overstress may significantly shorten the duration of the initiation. Overall, our results provide guidelines for determining the size of the asperity and overstress to minimize the effects of the forced initiation on the subsequent spontaneous

  7. Energy, Transportation, Air Quality, Climate Change, Health Nexus: Sustainable Energy is Good for Our Health

    Directory of Open Access Journals (Sweden)

    Larry E. Erickson

    2017-02-01

    Full Text Available The Paris Agreement on Climate Change has the potential to improve air quality and human health by encouraging the electrification of transportation and a transition from coal to sustainable energy. There will be human health benefits from reducing combustion emissions in all parts of the world. Solar powered charging infrastructure for electric vehicles adds renewable energy to generate electricity, shaded parking, and a needed charging infrastructure for electric vehicles that will reduce range anxiety. The costs of wind power, solar panels, and batteries are falling because of technological progress, magnitude of commercial activity, production experience, and competition associated with new trillion dollar markets. These energy and transportation transitions can have a very positive impact on health. The energy, transportation, air quality, climate change, health nexus may benefit from additional progress in developing solar powered charging infrastructure.

    1997-12-31

    T.R. Lakshmanan, director of the Bureau of Transportation Statistics, offered the following definition from the Bruntland Commission: ``Sustainable development is development that meets the needs of the present generations without compromising the ability of future generations.`` The technologies and policies that received the most attention would provide per-unit-of-service reduction of three kinds of social costs (external costs, in economist`s terminology) with respect to light duty transportation. The main factors to be reduced were oil use, greenhouse gases, and air pollution. Undesirable side effects of continually expanding transportation activity, including congestion and habitat loss, were also discussed. The conference included debate about priorities among these five categories of social cost, about which organizations should take action to achieve the reductions needed in each, and about what specific actions these organizations should take.

  10. Initial and sustained brain responses to threat anticipation in blood-injection-injury phobia

    Directory of Open Access Journals (Sweden)

    Leonie Brinkmann

    2017-01-01

    Full Text Available Blood-injection-injury (BII phobia differs from other subtypes of specific phobia in that it is associated with elevated disgust-sensitivity as well as specific autonomic and brain responses during processing of phobia-relevant stimuli. To what extent these features play a role already during threat anticipation is unclear. In the current fMRI experiment, 16 female BII phobics and 16 female healthy controls anticipated the presentation of phobia-specific and neutral pictures. On the behavioral level, anxiety dominated the anticipatory period in BII phobics relative to controls, while both anxiety and disgust were elevated during picture presentation. By applying two different models for the analysis of brain responses to anticipation of phobia-specific versus neutral stimuli, we found initial and sustained increases of activation in anterior cingulate cortex (ACC, insula, lateral and medial prefrontal cortex (PFC, thalamus and visual areas, as well as initial activation in the amygdala for BII phobics as compared to healthy controls. These results suggest that BII phobia is characterized by activation of a typical neural defense network during threat anticipation, with anxiety as the predominant emotion.

    2015-02-01

    Relative to drugs, diagnostics, and vaccines, efforts to develop other global health technologies, such as medical devices, are limited and often focus on the short-term goal of prototype development instead of the long-term goal of a sustainable business model. To develop a medical device to address neonatal hypothermia for use in resource-limited settings, we turned to principles of design theory: (1) define the problem with consideration of appropriate integration into relevant health policies, (2) identify the users of the technology and the scenarios in which the technology would be used, and (3) use a highly iterative product design and development process that incorporates the perspective of the user of the technology at the outset and addresses scalability. In contrast to our initial idea, to create a single device, the process guided us to create two separate devices, both strikingly different from current solutions. We offer insights from our initial experience that may be helpful to others engaging in global health technology development.

    This paper demonstrates a systems framework for assessment of environmental impacts from 'green initiatives', through a case study of meso-scale, anthropogenic-biogenic interactions. The following cross-sectoral green initiatives, combining the emerging trends in the North East region of the United Kingdom, have been considered - increasing the vegetation cover; decarbonising road transport; decentralising energy production through biomass plants. Two future scenarios are assessed - Baseline_2020 (projected emissions from realisation of policy instruments); Aggressive_2020 (additional emissions from realisation of green initiatives). Resulting trends from the Aggressive_2020 scenario suggest an increase in emissions of pollutant precursors, including biogenic volatile organic compounds and nitrogen dioxide over the base case by up to 20% and 5% respectively. This has implications for enhanced daytime ozone and secondary aerosols formation by up to 15% and over 5% respectively. Associated land cover changes show marginal decrease of ambient temperature but modest reductions in ammonia and ambient particulates. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available With increasing urbanization in China, many cities are facing serious environmental problems due to continuous and substantial increase in automobile transportation. It is becoming imperative to examine effective ways to reduce individual automobile use to facilitate sustainable transportation behavior. Empirical, theory-based research on sustainable transportation in China is limited. In this research, we propose an integrated model based on the norm activation model and the theory of planned behavior by combining normative and rational factors to predict individuals’ intention to reduce car use. Data from a survey of 600 car drivers in China’s three metropolitan areas was used to test the proposed model and hypotheses. Results showed that three variables, perceived norm of car-transport reduction, attitude towards reduction, and perceived behavior control over car-transport reduction, significantly affected the intention to reduce car-transport. Personal norms mediated the relationship between awareness of consequences of car-transport, ascription of responsibility of car-transport, perceived subjective norm for car-transport reduction, and intention to reduce car-transport. The results of this research not only contribute to theory development in the area of sustainable transportation behavior, but also provide a theoretical frame of reference for relevant policy-makers in urban transport management.

    Full Text Available To begin to meet the need for cataract surgery in sub-Saharan Africa, the cataract surgical rate (CSR should be at least 2,000 to 3,000; i.e. there should be 2,000-3,000 cataract operations per million population, per year. The current levels are below 1,000 (and often much lower. Sub-Saharan Africa poses a unique set of challenges: low population density; inadequate transportation systems that inhibit access; big differences in wealth; and a shortage of eye care resources (which are usually concentrated in larger cities. Additional issues relate to productivity, the supply chain and the quality of outcomes, all of which contribute to the low cataract surgical rates. It is in this context that the Hilton Foundation sought to enhance cataract surgical services in sub-Saharan Africa, through the Hilton Cataract Initiative.

  18. Sustainable Transportation: Accelerating Widespread Adoption of Energy Efficient Vehicles & Fuels (Brochure)

    2014-12-01

    While energy efficient transportation strategies have the potential to simultaneously slash oil consumption and reduce greenhouse gas (GHG) emissions, a truly sustainable solution will require more than just putting drivers behind the wheels of new fuel-efficient cars. As the only national laboratory dedicated 100% to renewable energy and energy efficiency, the National Renewable Energy Laboratory (NREL) accelerates widespread adoption of high-performance, low-emission, energy-efficient passenger and freight vehicles, as well as alternative fuels and related infrastructure. Researchers collaborate closely with industry, government, and research partners, using a whole-systems approach to design better batteries, drivetrains, and engines, as well as thermal management, energy storage, power electronic, climate control, alternative fuel, combustion, and emission systems. NREL's sustainable transportation research, development, and deployment (RD&D) efforts are not limited to vehicles, roads, and fueling stations. The lab also explores ways to save energy and reduce GHGs by integrating transportation technology advancements with renewable energy generation, power grids and building systems, urban planning and policy, and fleet operations.

    2006-12-01

    This paper examines the factors that have enabled the Healthy Cities Noarlunga (HCN) initiative to be sustainable over 18 years (1987-2005). Sustainability related to the ability of the initiative to continue to operate continuously in a manner that indicated its existence was accorded value by the community and local service providers. The analysis is based on a narrative review of 29 documents related to HCN, including a number of evaluations. Nine factors emerged as important to ensuring sustainability: strong social health vision; inspirational leadership; a model that can adapt to local conditions; ability to juggle competing demands; strongly supported community involvement that represents genuine engagement; recognition by a broad range of players that Healthy Cities is a relatively neutral space in which to achieve goals; effective and sustainable links with a local university; an outward focus open to international links and outside perspectives; and, most crucial, the initiative makes the transition from a project to an approach and a way of working. These sustainability factors are likely to be relevant to a range of complex, community-based initiatives.

The methodology is described, which combines on-street and laboratory measurement with modelling of the movement of air, vehicles, and vehicle exhaust emissions. The relationship between this kind of assessment and more realistic indicators of sustainability is discussed. The value of large-scale interdisciplinary research in this area is thus demonstrated.

    2015-01-01

    The paper reports research involving three cost–benefit analyses performed on different ITS schemes (Active Traffic Management, Intelligent Speed Adaptation and the Automated Highway System) on one of the UK's busiest highways — the M42. The environmental scope of the assets involved is widened to take into account the possibility of new technology linked by ICT and located within multiple spatial regions. The areas focused on in the study were data centre energy emissions, the embedded emissions of the road-side infrastructure, vehicle tailpipe emissions, additional hardware required by the vehicles (if applicable) and safety, and all aspects of sustainability. Dual discounting is applied which aims to provide a separate discount rate for environmental elements. For ATM, despite the energy costs of the data centre, the initial implementation costs and mitigation costs of its embedded emissions, a high cost–benefit ratio of 5.89 is achieved, although the scheme becomes less effective later on its lifecycle due to rising costs of energy. ISA and AHS generate a negative result, mainly due to the cost of getting the vehicle on the road. In order to negate these costs, the pricing of the vehicle should be scaled depending upon the technology that is outfitted. Retrofitting on vehicles without the technology should be paid for by the driver. ATM will offset greenhouse gas emissions by 99 kt of CO 2 equivalency over a 25 year lifespan. This reduction has taken into account the expected improvement in vehicle technology. AHS is anticipated to save 280 kt of CO 2 equivalency over 15 years of operational usage. However, this offset is largely dependent on assumptions such as the level of market penetration. - Highlights: • Three cost–benefit analyses are applied to inter-urban intelligent transport. • For ATM, a high cost–benefit ratio of 5.89 is achieved. • ATM offsets greenhouse gas emissions by 99 kt of CO 2 equivalency over 25 years. • ISA and AHS

    Ayer Keroh Toll that under the administration of Hang Tuah Jaya Municipal Council (HTJMC) is the main entrance for the people to enter to the city from North-South Expressway. This situation causes congestion to happen in this area especially during weekend and holiday and lead to air pollution. Hence, it is important to solve this problem beginning with the transport system and brings the city toward the sustainable way by learning the foreign city experience. In this research, the researchers start to revise the case study from foreign city councils on what and how they improve their cities transport system in term of sustainability. There are total of 17 case studies been studied including the cities that recognize with Sustainable Transport Award (STA) and other special activity and event that held worldwide. These cases studied are merged with the behavioral modification. There are four methods of changing behavior: positive reinforcement, negative reinforcement, punishment and extinction. Besides, the data from the administrative staff (HTJMC's officer) also important to success the planning. There are 16 officers that involved in this research and the data that obtained is used as the primary data resources. By knowing the behavioral modification and suggestion that brought by each case studies, the researchers will conclude whether the solution practicable in Ayer Keroh, Melaka or not. Throughout the research, the researchers can conclude that the not all the foreign experience is practical in Ayer, Keroh, Melaka due to the problem of weather, culture and technology that available in the city. The experience from foreign city cannot be exactly to implement in the city but need to redesign to match culture in the city.

  4. Energy conservation in urban areas in the framework of a sustainable transportation concept

    Shahin, M.

    2001-07-01

    The widespread of transport is recognized as a major contributor to an extensive range of undesirable side effects, covering all stages, from production to use and disposal. The transport sector is one of the major consumers of energy mainly fossil fuels and therefore contributes adverse emissions with local direct health effects as well as a significant share of 'greenhouse gases' (GHGs), which play a crucial role in determining the earth's climate. Moreover, the transportation sector is implicated in causing some social problems such as intensive use of public space. Present growth in vehicle ownership and use in urban areas, is unsustainable. Petroleum fuels, which are the main energy source for the transport sector, are essentially non-renewable. In short, the transportation system is unsustainable and is becoming more unsustainable. Measures need to be taken at a number of levels to mitigate the negative effects of transport and to reduce the increasing dependence on the fossil fuels as a main transportation energy soruce. The main objectives of this study are: (a) analyzing the transportation's role in the energy markets and its related environmental problems and defining the sustainable transport in urban areas, (b) analyzing alternative urban planning philosophies, (c) presenting a suggested procedure for sustainable develop ment of urban transport and energy consumption, (d) identifying the potential impacts of this procedure by being applied to Alexandria city, as a case study. The identification is based on evaluating four different scenarios for the year 2015 which are compared to each other, as well as with a business-as usual scenario (Do-Nothing Solution). These scenarios are based on the proposed sustainable transport and energy systems started from (Do-Minimum Solution) until (Do-Maximum Solution). To facilitate the calculations, an interactive computer program called 'TraEnergy' is developed in the framework of this

    The Ecological Society of America (ESA) has responded to the growing commitment among ecologists to make their science relevant to society through a series of concerted efforts, including the Sustainable Biosphere Initiative (1991), scientific assessment of ecosystem management (1996), ESA’s vision for the future (2003), Rapid Response Teams that respond to environmental crises (2005), and the Earth Stewardship Initiative (2009). During the past 25 years, ESA launched five new journals, largely reflecting the expansion of scholarship linking ecology with broader societal issues. The goal of the Earth Stewardship Initiative is to raise awareness and to explore ways for ecologists and other scientists to contribute more effectively to the sustainability of our planet. This has occurred through four approaches: (1) articulation of the stewardship concept in ESA publications and Website, (2) selection of meeting themes and symposia, (3) engagement of ESA sections in implementing the initiative, and (4) outreach beyond ecology through collaborations and demonstration projects. Collaborations include societies and groups of Earth and social scientists, practitioners and policy makers, religious and business leaders, federal agencies, and artists and writers. The Earth Stewardship Initiative is a work in progress, so next steps likely include continued nurturing of these emerging collaborations, advancing the development of sustainability and stewardship theory, improving communication of stewardship science, and identifying opportunities for scientists and civil society to take actions that move the Earth toward a more sustainable trajectory.

  6. Towards sustainable urban transportation: Test, demonstration and development of fuel cell and hybrid-electric buses

    Several aspects make today's transport system non-sustainable: - Production, transport and combustion of fossil fuels lead to global and local environmental problems. - Oil dependency in the transport sector may lead to economical and political instability. - Air pollution, noise, congestion and land-use may jeopardise public health and quality of life, especially in urban areas. In a sustainable urban transport system most trips are made with public transport because high convenience and comfort makes travelling with public transport attractive. In terms of emissions, including noise, the vehicles are environmentally sustainable, locally as well as globally. Vehicles are energy-efficient and the primary energy stems from renewable sources. Costs are reasonable for all involved, from passengers, bus operators and transport authorities to vehicle manufacturers. The system is thus commercially viable on its own merits. This thesis presents the results from three projects involving different concept buses, all with different powertrains. The first two projects included technical evaluations, including tests, of two different fuel cell buses. The third project focussed on development of a series hybrid-bus with internal combustion engine intended for production around 2010. The research on the fuel cell buses included evaluations of the energy efficiency improvement potential using energy mapping and vehicle simulations. Attitudes to hydrogen fuel cell buses among passengers, bus drivers and bus operators were investigated. Safety aspects of hydrogen as a vehicle fuel were analysed and the use of hydrogen compared to electrical energy storage were also investigated. One main conclusion is that a city bus should be considered as one energy system, because auxiliaries contribute largely to the energy use. Focussing only on the powertrain is not sufficient. The importance of mitigating losses far down an energy conversion chain is emphasised. The Scania hybrid fuel cell

    2017-02-01

    Alkaline direct ethanol fuel cells (DEFC), which convert the chemical energy stored in ethanol directly into electricity, are one of the most promising energy-conversion devices for portable, mobile and stationary power applications, primarily because this type of fuel cell runs on a carbon-neutral, sustainable fuel and the electrocatalytic and membrane materials that constitute the cell are relatively inexpensive. As a result, the alkaline DEFC technology has undergone a rapid progress over the last decade. This article provides a comprehensive review of transport phenomena of various species in this fuel cell system. The past investigations into how the design and structural parameters of membrane electrode assemblies and the operating parameters affect the fuel cell performance are discussed. In addition, future perspectives and challenges with regard to transport phenomena in this fuel cell system are also highlighted.

    International commerce places unique pressures on the sustainability of water resources and marine environments. System impacts include noise, emissions, and chemical and biological pollutants like introduction of invasive species into key ecosystems. At the same time, maritime trade also enables the sustainability ambition of intragenerational equity in the economy through the global circulation of commodities and manufactured goods, including agricultural, energy and mining resources (UN Trade and Development Board 2013). This paper presents a framework to guide the analysis of the multiple dimensions of the sustainable commerce-ocean nexus. As a demonstration case, we explore the social, economic and environmental aspects of the nexus framework using scenarios for the production and transportation of conventional and bio-based energy commodities. Using coupled LCA and GIS methodologies, we are able to orient the findings spatially for additional insight. Previous work on the sustainable use of marine resources has focused on distinct aspects of the maritime environment. The framework presented here, integrates the anthropogenic use, governance and impacts on the marine and coastal environments with the natural components of the system. A similar framework has been highly effective in progressing the study of land-change science (Turner et al 2007), however modification is required for the unique context of the marine environment. This framework will enable better research integration and planning for sustainability objectives including mitigation and adaptation to climate change, sea level rise, reduced dependence on fossil fuels, protection of critical marine habitat and species, and better management of the ocean as an emerging resource base for the production and transport of commodities and energy across the globe. The framework can also be adapted for vulnerability analysis, resilience studies and to evaluate the trends in production, consumption and

    2017-06-01

    Full Text Available Both the domestic and international academic literature’s analysis of links between transport and wellbeing focuses mainly on urban settings and vulnerable population groups including older people, people with health issues, socio-economically disadvantaged people, or people undergoing more frequent extreme climatic events. While the relationship between remote Australians wellbeing and travelling activities is evident, its complexity still remains an under-researched topic. This is paradoxical when considering that extreme distances, high supply chain costs, limited access to services and to economic participation are well recognised obstacles for sustaining vibrant remote Australian communities. The latest accessibility-driven technological innovations in both the digital and the sharing economies are highly topical in transport projects in urban agglomerations but still a distant reality for remote Australia. There is a need for researching an appropriateness framework of such technologies because of the strong relevance of the multiple outcomes in terms of wellbeing that some of these innovations provide. Furthermore what defines a good quality of life can sometimes be very similar and other times greatly differ between remote and urban contexts. In the light of some recent transport and mobility research this paper analyses the potential connections between more appropriate transport innovations and increasingly resilient remote communities.

    Abstract Background The core elements provide a framework for nursing homes (NH) to establish antibiotic stewardship programs (ASP). We report on implementation and sustainability of ASP through a hospital-NH partnership. Methods Since 2014, a hospital-based team (HBT) assisted 9 NH in Monroe County, NY in implementing ASP. Enrollment was staggered; data are currently available from 2 NH: Facility X (470 beds, full-time medical director and Infection Preventionist (IP)) and Facility Y (288 beds, part-time medical director and IP). The HBT analyzed antibiotic data to develop initial interventions focusing on reducing urinary tract infection (UTI) treatment and quinolone use. Activities included (1) regular presentation of antibiotic days of therapy (DOT), urine culture rates and treatment appropriateness; (2) coaching on interpretation and use of data to expand interventions; (3) creation of citywide guideline for diagnosis and treatment of common infections; and (4) education of nurses, providers, and families. Results The HBT provided drug expertise and support throughout the project; however, involvement of NH staff varied. The Facility X IP assumed responsibility for the review and feedback of urine culture data and education and the medical director educated clinicians and families on treatment guidelines. Facility Y’s ASP was led by the medical director and focused mainly on education of clinicians. Facility X saw significant reductions in all metrics in 2016. Facility Y significantly reduced their quinolone use and urine culture rate; however, this did not translate into a reduction in DOT for UTI (Table 1). Table 1.

    2010-06-01

    Full Text Available The World Commission on Dams (WCD has called for developers, governments, civil society, etc. to use its Strategic Priorities as a starting point for dialogue and initiatives to address issues regarding the development of dams. One very notable follow-up initiative has been led by the hydropower industry. The International Hydropower Association developed Sustainability Guidelines (IHA, 2004 and a Sustainability Assessment Protocol (IHA, 2006, and most recently has been involved in a two-year process with governments, NGOs and the finance sector to develop a broadly endorsed sustainability assessment tool based on review and update of the IHA Sustainability Assessment Protocol. This cross-sectoral process, known as the Hydropower Sustainability Assessment Forum (HSAF, has drawn on the knowledge base and many of the findings and recommendations of the World Commission on Dams, as well as a number of other developments in the last ten years. A fundamental premise of the work of the Forum is that an industry-driven and -owned initiative has far-reaching potential to influence performance in the hydropower sector. At the same time, the potential for the use of a broadly endorsed sustainability assessment tool for hydropower by those in other sectors is well recognised and aspired to by the Forum. This paper describes the work of the Forum up to August 2009 and the contents of the Draft Protocol released publicly in August 2009, and considers some of the commonalities and points of departure between this process and the WCD. The Forum’s work on the Hydropower Sustainability Assessment Protocol is a work in progress, so this paper can describe but not give a full analysis of the work while it is in train.

    Cities undergoing climate change and rapid urbanization are faced with significant transformational processes that affect the environment and society, challenging them to become more sustainable and resilient. The promotion of nature-based solutions represents an efficient approach to meet sustainability targets in cities and improve the quality of life of citizens. The association of large components of green infrastructure, such as urban parks, with physical activity can counteract the sedentary lifestyle endemic to cities and improve the overall health and well-being of individuals (Carrus et al., 2013; Scopelliti et al., 2016). By promoting a sustainable means of transport and connecting green spaces within a highly urbanized city, bicycle lanes represent an effective tool for associating physical activity with nature in cities allowing bicycle users to benefit from the positive health effects of nature-based solutions. Our study focuses on the potential of bicycle lanes to improve functional connectivity among green spaces. We administered 820 questionnaires in 34 green spaces (i.e., urban parks) in Bucharest, Romania, to identify the factors influencing the use of bicycle lanes connecting urban parks and to understand which planning criteria for bicycle lanes are considered as the most important by park visitors. We applied binary and ordinal logistic regressions and found that the factors affecting bicycle lane use are illegally parked cars and lack of accessibility to urban parks. The criteria preferred by park visitors for bicycle lane planning are determined by experience level and frequency of bicycle use. To develop a functional and integrated bicycle lane network that can make cities healthier and more sustainable, policy makers are advised to engage in a public participatory process and focus on the needs of bicycle users.

    The predictive methods currently used for material specification, component design and the development of manufacturing processes, need to evolve beyond the current `metal centric' state of the art, if advanced composites are to realise their potential in delivering sustainable transport solutions. There are however, significant technical challenges associated with this process. Deteriorating environmental, political, economic and social conditions across the globe have resulted in unprecedented pressures to improve the operational efficiency of the manufacturing sector generally and to change perceptions regarding the environmental credentials of transport systems in particular. There is a need to apply new technologies and develop new capabilities to ensure commercial sustainability in the face of twenty first century economic and climatic conditions as well as transport market demands. A major technology gap exists between design, analysis and manufacturing processes in both the OEMs, and the smaller companies that make up the SME based supply chain. As regulatory requirements align with environmental needs, manufacturers are increasingly responsible for the broader lifecycle aspects of vehicle performance. These include not only manufacture and supply but disposal and re-use or re-cycling. In order to make advances in the reduction of emissions coupled with improved economic efficiency through the provision of advanced lightweight vehicles, four key challenges are identified as follows: Material systems, Manufacturing systems, Integrated design methods using digital manufacturing tools and Validation systems. This paper presents a project which has been designed to address these four key issues, using at its core, a digital framework for the creation and management of key parameters related to the lifecycle performance of thermoplastic composite parts and structures.

  20. Sustainability Measures of Urban Public Transport in Cities: A World Review and Focus on the Asia/Middle East Region

    Directory of Open Access Journals (Sweden)

    Chris De Gruyter

    2016-12-01

    Full Text Available Previous studies of public transport sustainability in cities have been very limited to date, particularly in more developing countries located throughout Asia and the Middle East. This paper assesses the sustainability of urban public transport systems in cities by adopting a quantitative measurement framework containing 15 public transport sustainability indicators. It compares aggregate sustainability performance of urban public transport in international regions of cities, and then examines the relative sustainability of selected cities in the Asia and Middle East region. The world region analysis shows that Eastern Europe, Asia, and Latin America achieve the highest aggregate normalised scores for sustainable public transport, in that order. In general, the results suggest that western developed countries (Western Europe, North America, and Oceania have better performance on environmental and social indicators but poorer performance on system effectiveness and economic indicators. Asia and Latin America perform the other way round; better on economic and system effectiveness and worse on social and environmental indicators. Eastern Europe is one of the few regions with higher level performance all round. The city-based analysis of Asia/Middle East suggested that out of the 26 cities studied, the top 3 cities in terms of sustainable public transport in the Asia and Middle East Region are: 1st, Manila (Philippines; 2nd, Tokyo (Japan; and 3rd, Chennai (India. Dubai (United Arab Emirates (UAE, rated 26th, Shizuoka (Japan, rated 25th and Kuala Lumpur (Malaysia, rated 24th were the lowest rated cities. The paper explores the implications of the findings and makes suggestions for future research.

  1. Modeling the role of public transportation in sustaining tuberculosis transmission in South Africa.

    2013-03-15

    Current tuberculosis notification rates in South Africa are among the highest ever recorded. Although the human immunodeficiency virus epidemic has been a critical factor, the density of respiratory contacts in high-risk environments may be an important and underappreciated driver. Using a modified Wells-Riley model for airborne disease transmission, we estimated the risk of tuberculosis transmission on 3 modes of public transit (minibus taxis, buses, and trains) in Cape Town, South Africa, using exhaled carbon dioxide as a natural tracer gas to evaluate air exchange. Carbon dioxide measurements were performed between October and December of 2011. Environmental risk, reflected in the rebreathed fraction of air, was highest in minibus taxis and lowest in trains; however, the average number of passengers sharing an indoor space was highest in trains and lowest in minibus taxis. Among daily commuters, the annual risk of tuberculosis infection was projected to be 3.5%-5.0% and was highest among minibus taxi commuters. Assuming a duration of infectiousness of 1 year, the basic reproductive number attributable to transportation was more than 1 in all 3 modes of transportation. Given its poor ventilation and high respiratory contact rates, public transportation may play a critical role in sustaining tuberculosis transmission in South African cities.

    The main advantage of using GIS is its ability to access and analyze spatially distributed data. The applications of GIS to transportation can be viewed as involving either on data retrieval; data integrator; or data analysis. The use of remote sensing can assist the retrieval of land use changes. Indeed, the integration of GIS and remote sensing will be used to fill the gap in the smart transport planning. A four step research is going to be done in order to try to integrate the usage of GIS and remote sensing to sustainable transport planning. The proposed research will be held in the city of Limassol, Cyprus. The data that are going to be used are data that are going to be collected through questionnaires, and other available data from the Cyprus Public Works Department and from the Remote Sensing Laboratory and Geo-Environment Research Lab of the Cyprus University of Technology. Overall, statistical analysis and market segmentation of data will be done, the land usage will be examined, and a scenario building on mode choice will be held. This paper presents an overview of the methodology that will be adopted.

  3. Fostering Sustainable Transportation Operations through Corridor Management: A Simulation Gaming Approach

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Synchromodality is described as a network of well-synchronised and interconnected transportation modes. One of the most important advantages of synchromodality is the development of a sustainable transportation system. Given the numerous stakeholders and network interdependencies within freight transport corridors, achieving efficient coordination and management is complex. In this paper, we regard information exchange as one of the main enablers of collaboration between the infrastructure managers. We developed a digital single-player simulation game called “Modal Manager” comprising logistic service providers and infrastructure managers. Each player takes over the role of an infrastructure manager who must use information provision as a tool to control flows in a network where various planned and unplanned disruptions occur. We include the game in a session where participants are able to interact with the game and with each other. The first gameplay session with Dutch experts revealed that infrastructure managers perceive synchromodality as a way to cope with disruptions more efficiently. On the other hand, the concept of synchromodal corridor management is ambiguous and various legal and governance barriers exist that hinder its implementation.

    This paper present the BEST project - Bio Ethanol for Sustainable Transport, that aims to promote the ethanol usage, replacing diesel, in the urban public transport in Brazil and worldwide. Apart from Sao Paulo, leading city in the Americas, another eight cities located in Europe and Asia takes part in the project. One of the Brazilian project's goals is to evaluate ethanol usage as diesel fuel replacement in public transport buses by comparatively following the operational output of the experimental fleet, taking as reference an equivalent diesel bus. The utilized test vehicles will be evaluated and monitored to demonstrate ethanol energetic efficiency and, after the results the BEST project and the European Union will set a blue print for public policies to incentive ethanol usage in the urban public transport. The results will allow identifying technical and economical barriers that will eventually overlap the viability process of this technology in the Brazilian public transport. (author)

    2007-05-30

    This report documents numerical flow and transport simulations performed that establish initial waste acceptance criteria for the potential waste streams that may be safely sequestered in the 221-U Building and similar canyon structures. Specifically, simulations were executed to identify the maximum loading of contaminant mass (without respect to volume) that can be emplaced within the 221-U Building with no more than 1 pCi/m2 of contaminant migrating outside the structure within a 1,000 year time period. The initial scoping simulations were executed in one dimension to assess important processes, and then two dimensions to establish waste acceptance criteria. Two monolithic conditions were assessed: (1) a grouted canyon monolith; and (2) a canyon monolith filled with sand, both assuming no cracks or fissures were present to cause preferential transport. A three-staged approach was taken to account for different processes that may impact the amount of contaminant that can be safely sequestered in canyon structure. In the first stage, flow and transport simulations established waste acceptance criteria based on a linear (Kd) isotherm approach. In the second stage, impacts on thermal loading were examined and the differences in waste acceptance criteria quantified. In the third stage of modeling, precipitation/dissolution reactions were considered on the release and transport of the contaminants, and the subsequent impact on the maximum contaminant loading. The reactive transport modeling is considered a demonstration of the reactive transport capability, and shows the importance of its use for future performance predictions once site-specific data have been obtained.

    Dutch transport scenarios for the OECD project on Environmental Sustainable Transport (EST) are described in this Phase 3 report of the project. The EST project contains a business-as-usual scenario (BAU) and three EST scenarios which attain the EST criteria (i.e. a reduction of CO2 by 80%, NOx by 90%, VOC by 90%, PM10 by 90%): (1) a 'high-technology' scenario containing only technological changes, (2) a 'mobility-management' scenario containing only mobility changes, (3) a combination scenario containing a combination of technological and mobility changes. Furthermore, the report describes possible instrument packages for the implementation of EST and the social and economic impacts of EST. The main conclusions are: (1) only if a high increase in technological developments and/or very stringent behaviour adaptations and changes in spatial and economic structures at the national and international level are assumed, the EST criteria can be met, (2) if EST is to be realised, measures will have to be taken in the short term and innovative policy instruments must be developed and implemented. The implementation of the tradeable CO2 emission permit system for passenger and freight transport is crucial for the attainment of EST, (3) a timely implementation of the policy instruments for the attainment of EST means that the current policy life cycle must radically change, (4) the level of material wealth (expressed in GDP) and employment will be somewhat slower in EST compared to BAU, but several social factors will improve. Firstly, differences between societal groups in (a) travel behaviour, (b) the level of accessibility of economic and social opportunities and (c) (perceived) environmental quality will decrease. Secondly, the level of motorised transport will be strongly reduced which will improve traffic safety and reduce health problems caused by local air pollution and noise nuisance from road traffic and aviation

    Physical inactivity is one of the leading risk factors for non-communicable diseases, yet many are not sufficiently active. The Physical Activity through Sustainable Transport Approaches (PASTA) study aims to better understand active mobility (walking and cycling for transport solely or in combination with public transport) as an innovative approach to integrate physical activity into individuals' everyday lives. The PASTA study will collect data of multiple cities in a longitudinal cohort design to study correlates of active mobility, its effect on overall physical activity, crash risk and exposure to traffic-related air pollution. A set of online questionnaires incorporating gold standard approaches from the physical activity and transport fields have been developed, piloted and are now being deployed in a longitudinal study in seven European cities (Antwerp, Barcelona, London, Oerebro, Rome, Vienna, Zurich). In total, 14000 adults are being recruited (2000 in each city). A first questionnaire collects baseline information; follow-up questionnaires sent every 13 days collect prospective data on travel behaviour, levels of physical activity and traffic safety incidents. Self-reported data will be validated with objective data in subsamples using conventional and novel methods. Accelerometers, GPS and tracking apps record routes and activity. Air pollution and physical activity are measured to study their combined effects on health biomarkers. Exposure-adjusted crash risks will be calculated for active modes, and crash location audits are performed to study the role of the built environment. Ethics committees in all seven cities have given independent approval for the study. The PASTA study collects a wealth of subjective and objective data on active mobility and physical activity. This will allow the investigation of numerous correlates of active mobility and physical activity using a data set that advances previous efforts in its richness, geographical coverage

    2017-04-01

    Full Text Available Non-homogeneous debris flows generally occur during the rainy seasons in Southwest China, and have received considerable attention in the literature. Regarding the complexity in debris flow dynamics, experimental approaches have proven to be effective in revealing the formative mechanism for debris flow, and quantifying the relations between the various influencing factors with debris-flow formation and subsequent transport processes. Therefore, a flume-based and experimental study was performed at the Debris Flow Observation and Research Station of Jiangjia Gully in Yunnan Province, to theoretically analyze favorable conditions for debris-flow formation and initial transport by selecting the median particle size d50, flow rate Q, vertical grading coefficient ψ, slopes S, and the initial soil water contents W as the five variables for investigation. To achieve this, an optimal combination of these variables was made through an orthogonal experimental design to determine their relative importance upon the occurrence and initial mobilization behavior of a debris flow and to further enhance our insight into debris-flow triggering and transport mechanisms.

    Full Text Available This article proposes to transform the current production model through the organization of an agricultural system based on the concepts of crop-livestock-forestry integration (ICLF. We used the guidelines and concepts related to the Green Economy Initiative (GEI, a proposal of the United Nations Environment Program (UNEP. Within this framework, the agricultural sector is identified as an important sector due to its strong connection with economic, social and environmental dimensions. We intend to demonstrate that the ICLF proposal is in line with aspects of sustainable agriculture, as proposed by GEI, and that it is an important strategy to increase production in a sustainable manner in Brazil. The adoption of GEI is a consistent strategy for the implementation of policies to promote sustainable development.

    Full Text Available In the economic field, especially in tourism, initiative and innovation are effective ways to finding new approaches to various problems occurring with time or unforeseen, which leads to greater adaptation to ever-changing environment of economic life and resistance to shocks, experience having a decisive role. In terms of sustainable tourism not any initiative even if it is an innovative one is appropriate, it is the sector where actions must be thought out long-term and to exist concerns in achieving sustainability in all four branches simultaneously (economic, social, environmental and cultural. In order to achieve sustainable development in the true sense it is not enough to only meet the needs to one of them. Therefore, the challenge lies in finding optimal solutions for each branch separately, but also for making their relationship become sustainable. The need to continually adapt and monitoring the results to improve them, have a primary importance. The paper aims at analyzing in terms of advantages and disadvantages of new tourism forms implementation in a fragile environment as delta, which needs special attention in that it can't be operated at high tourism level, such as mass tourism.

    2010-01-01

    Full Text Available Over the last twenty years, there has been growing international recognition of the importance of education in encouraging sustainable development. There is now a plethora of action plans and strategies from various Government departments expecting teachers to play an important part in this and, in the Lifelong Learning Sector, providers are expected to embed sustainability within their provision from 2010. This paper explains how the teacher education team at Somerset College, as part of the University of Plymouth partnership which provides the Professional Graduate Certificate in Education/Certificate in Education which incorporate the Diploma in Teaching in the Lifelong Learning Sector, embedded Education for Sustainable Development within these programmes. They used a co-operative inquiry approach to carry out the professional and curriculum development required and are now sharing this within the partnership and further afield. The main focus of this paper is the Education for Sustainable Development curriculum development undertaken; a forthcoming paper (Summers and Turner, in review will explore the cooperative inquiry process and how this supported the development.

    European maritime companies have adopted programs to limit operational impacts on the environment. For maritime companies in North America, the Green Marine Environmental Program (GMEP) offers a framework to establish and reduce environmental footprints. Green Marine (GM) participants demonstrate annual improvements of specific environmental performance indicators (e.g., reductions in air pollution emissions) to maintain certification. Participants complete annual self-evaluations with results determining rankings for performance indicators on a 1-to-5 scale. Self-evaluations are independently verified every two years to ensure rigor and individual results are made publicly available annually to achieve transparency. GM benefits the marine industry across North America by encouraging sustainable development initiatives. GM's credibility is reflected through a diverse network of environmental groups and government agencies that endorse and help shape the program. Merits of this relatively new maritime certification (not previously described in the academic literature), are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    We describe the three dimensional global stratospheric chemistry model developed under the NASA Global Modeling Initiative (GMI) to assess the possible environmental consequences from the emissions of a fleet of proposed high speed civil transport aircraft. This model was developed through a unique collaboration of the members of the GMI team. Team members provided computational modules representing various physical and chemical processes, and analysis of simulation results through extensive comparison to observation. The team members' modules were integrated within a computational framework that allowed transportability and simulations on massively parallel computers. A unique aspect of this model framework is the ability to interchange and intercompare different submodules to assess the sensitivity of numerical algorithms and model assumptions to simulation results. In this paper, we discuss the important attributes of the GMI effort, describe the GMI model computational framework and the numerical modules representing physical and chemical processes. As an application of the concept, we illustrate an analysis of the impact of advection algorithms on the dispersion of a NO{sub y}-like source in the stratosphere which mimics that of a fleet of commercial supersonic transports (High-Speed Civil Transport (HSCT)) flying between 17 and 20 kilometers.

    The Global Modeling Initiative (GMI) Team developed objective criteria for model evaluation in order to identify the best representation of the stratosphere. This work created a method to quantitatively and objectively discriminate between different models. In the original GMI study, 3 different meteorological data sets were used to run an offline chemistry and transport model (CTM). Observationally-based grading criteria were derived and applied to these simulations and various aspects of stratospheric transport were evaluated; grades were assigned. Here we report on the application of the GMI evaluation criteria to CTM simulations integrated with a new assimilated wind data set and a new general circulation model (GCM) wind data set. The Finite Volume Community Climate Model (FV-CCM) is a new GCM developed at Goddard which uses the NCAR CCM physics and the Lin and Rood advection scheme. The FV-Data Assimilation System (FV-DAS) is a new data assimilation system which uses the FV-CCM as its core model. One year CTM simulations of 2.5 degrees longitude by 2 degrees latitude resolution were run for each wind data set. We present the evaluation of temperature and annual transport cycles in the lower and middle stratosphere in the two new CTM simulations. We include an evaluation of high latitude transport which was not part of the original GMI criteria. Grades for the new simulations will be compared with those assigned during the original GMT evaluations and areas of improvement will be identified.

    A regime with electron heat confinement improvement was recently found in the initial phase of discharges in the TUMAN-3M tokamak. An internal transport barrier (ITB) formation in this regime was confirmed by Thomson scattering measurements and by transport modelling. Two possible reasons for the ITB formation are discussed in the paper: by reduction of turbulent transport in the presence of low magnetic shear or by plasma sheared rotation. It is demonstrated that low magnetic shear formation is possible in the current ramp-up phase of the Ohmic discharge. The low magnetic shear does not seem to be the only reason for the transport reduction. Results of Doppler reflectometry measurements of poloidal rotation of density fluctuations are presented. It is found that core confinement improvement correlates with the appearance of sheared rotation of the density fluctuations and with a burst of the MHD activity. The ITB formation in the regime seems to be a result of a combined action of reduced magnetic shear and plasma sheared rotation

    The non-intercepting beam current monitoring systems suitable for a wide, range of beam parameters have been developed for the Advanced Photon Source (APS) low energy transport lines and high energy transport line. The positron or electron beam pulse in the transport lines wig have peak beam currents ranging from 8 mA to 29 A with pulse widths varying from 120 ps to 30 ns and pulse repetition rates from 2 Hz to 60 Hz. The peak beam current or total beam charge is measured with the fast or integrating current transformer, respectively, manufactured by Bergoz. In-house high speed beam signal processing electronics provide a DC level output proportional to the peak current or total charge for the digitizer input. The prototype systems were tested on the linacs which have beam pulse structures similar to that of the APS transport lines. This paper describes the design of beam signal processing electronics and grounding and shielding methods for current transformers. The results of the initial operations are presented. A short introduction on the preliminary design of current monitoring systems for the APS rings is also included

    Only one-third of the European population meets the minimum recommended levels of physical activity (PA). Physical inactivity is a major risk factor for non-communicable diseases. Walking and cycling for transport (active mobility, AM) are well suited to provide regular PA. The European research project Physical Activity through Sustainable Transport Approaches (PASTA) pursues the following aims: (1) to investigate correlates and interrelations of AM, PA, air pollution and crash risk; (2) to evaluate the effectiveness of selected interventions to promote AM; (3) to improve health impact assessment (HIA) of AM; (4) to foster the exchange between the disciplines of public health and transport planning, and between research and practice. PASTA pursues a mixed-method and multilevel approach that is consistently applied in seven case study cities. Determinants of AM and the evaluation of measures to increase AM are investigated through a large scale longitudinal survey, with overall 14,000 respondents participating in Antwerp, Barcelona, London, Örebro, Rome, Vienna and Zurich. Contextual factors are systematically gathered in each city. PASTA generates empirical findings to improve HIA for AM, for example, with estimates of crash risks, factors on AM-PA substitution and carbon emissions savings from mode shifts. Findings from PASTA will inform WHO's online Health Economic Assessment Tool on the health benefits from cycling and/or walking. The study's wide scope, the combination of qualitative and quantitative methods and health and transport methods, the innovative survey design, the general and city-specific analyses, and the transdisciplinary composition of the consortium and the wider network of partners promise highly relevant insights for research and practice. Ethics approval has been obtained by the local ethics committees in the countries where the work is being conducted, and sent to the European Commission before the start of the survey.

    Full Text Available Today, urban transportation has attracted urban planners’ and researchers' attention because of air and noise pollution problems associated with it. In Shahrkord city in Iran, no plans have been made for sustainable transportation, and the available poor transportation infrastructure is not responsive to the growing population of the city. This issue has inflicted the city with serious problems, including environmental pollution, traffic jams, and car accidents. Therefore, it is necessary for urban managers and planners to conduct necessary planning and analysis for the development of urban transportation system through a strategic perspective. In this study, the strengths and weaknesses as well as the opportunities and threats of Shahrkord transportation system are identified using strength, weakness, opportunity, threat (SWOT analysis. Status of the city's transportation system is determined through evaluation of internal and external factors. The results of SWOT analysis and the matrix of internal and external factors indicate that the internal and external evaluation factors are equal to 2.330 and 3.367, respectively, which means that Shahrekord transportation system holds a conservative situation. Considering the identified status, several strategies are proposed to improve the status quo. Finally, the proposed strategies are evaluated based on sustainable development indices, namely economic, environmental, and social indices, by using the fuzzy complex proportional assessment (COPRAS method. The results show that the best proposed strategy is attraction of private investors to set up pedestrian bridges equipped with escalators and the concession of using them for the establishment of environmental advertisement.

    Full Text Available The Chinese green Belt and Road initiative is promoted. This study takes Chengdu as a key hub under the Belt and Road initiative. The municipal solid waste disposal is the point to control pollution and move toward sustainability. Hence, sustainable municipal solid waste disposal needs to be studied. The prior studies are absent in the planning scenarios analysis. This study proposes a case study to propose three planning scenarios for waste disposal to enhance its sustainability. Scenario 1 represents the current waste disposal mode in Chengdu; Scenario 2 considers all the wastes being incinerated; and Scenario 3 focuses on the incorporation of three disposal methods, i.e., anaerobic digestion, incineration, and landfilling. These three scenarios are assessed based on their greenhouse gas emissions, costs, and public acceptance, to determine the optimality for future managerial practice. Results indicated that Scenario 3 has the highest overall efficiency, yet is challenging in terms of economic feasibility. The limitations of the study are also discussed.

    The Urban population of developing countries is predicted to rise from one third in 1990 to over 50% by 2025. In 1950 the world's total urban population was 734 million, of whom 448 million were living in developed countries and remaining 286 were in developing region. The total population on earth is predicted to increase by more than one billion people within the next 15 years, reaching 8.5 billion in 2030, and to increase further to 9.7 billion in 2050 and 11.2 billion by 2100. Looking at the ever increasing urbanization.In 2016, an estimated 54.5 per cent of the world's populations inhabited in urban region. By 2030, urban areas are projected to shelter 60 per cent of people worldwide and one in every three people will live in cities with at least half a million inhabitants.On the basis of these figures and other global trends, it would appear that Africa and Asia will have the highest share of world's urban growth in next 25 years, resulting consideration rise of large number of metropolitan cities and towns. Therefore issues related to urban climate change will be important for socio economic development for urban transformation through environmental sustainability.The information and communication systems plays an important role in achieving the social sustainability through environmental sustainability for urban transformation. This presentation aims to start the Global initiatives on the problem identifications in environment education for global transformation, education for socio-economic and environmental sustainability due to urbanization in 2050 to investigate problems related to social-economic risks and management issues resulting from urbanization to aid mitigation planning in globalized world and to educate scientists and local populations to form a basis for sustainable solutions in environment learning.The presentation aims to assess the potential of information and communication technology for environment education,both within different

  20. Concepts for Life Cycle Cost Control Required to Achieve Space Transportation Affordability and Sustainability

    Cost control must be implemented through the establishment of requirements and controlled continually by managing to these requirements. Cost control of the non-recurring side of life cycle cost has traditionally been implemented in both commercial and government programs. The government uses the budget process to implement this control. The commercial approach is to use a similar process of allocating the non-recurring cost to major elements of the program. This type of control generally manages through a work breakdown structure (WBS) by defining the major elements of the program. If the cost control is to be applied across the entire program life cycle cost (LCC), the approach must be addressed very differently. A functional breakdown structure (FBS) is defined and recommended. Use of a FBS provides the visibifity to allow the choice of an integrated solution reducing the cost of providing many different elements of like function. The different functional solutions that drive the hardware logistics, quantity of documentation, operational labor, reliability and maintainability balance, and total integration of the entire system from DDT&E through the life of the program must be fully defined, compared, and final decisions made among these competing solutions. The major drivers of recurring cost have been identified and are presented and discussed. The LCC requirements must be established and flowed down to provide control of LCC. This LCC control will require a structured rigid process similar to the one traditionally used to control weight/performance for space transportation systems throughout the entire program. It has been demonstrated over the last 30 years that without a firm requirement and methodically structured cost control, it is unlikely that affordable and sustainable space transportation system LCC will be achieved.

  1. The UN's 'Sustainable Energy for All' initiative is compatible with a warming limit of 2 °C

    Progress towards climate protection has been modest over the past decades despite the ever-increasing urgency for concerted action against global warming. Partly as a response to this, but more directly as a means to promote sustainable development and poverty eradication, the United Nations has initiated a process to promote three global energy objectives: energy access, renewable energy and energy efficiency. Here we discuss the consistency of the proposed energy-related objectives with the overarching climate goal of limiting global temperature increase to below 2 °C. We find that achieving the three energy objectives could provide an important entry point to climate protection, and that sustainability and poverty eradication can go hand in hand with mitigating climate risks. Using energy indicators as the sole metrics for climate action may, however, ultimately fall short of the mark: eventually, only limits on cumulative greenhouse gas emissions will lead to stringent climate protection.

    Full Text Available Lifestyle-related chronic diseases pose a considerable burden to the individual and the wider society, with correspondingly negative effects on industry. Obesity is a particular problem for the Australasian road and rail industries where it is associated with specific cardiac and fatigue-related safety risks, and levels are higher than those found in the general population. Despite this recognition, and the introduction of National Standards, very little consensus exists regarding approaches to preventative health for surface transport workers. A review of evidence regarding effective health promotion initiatives is urgently needed to inform best practice in this cohort. This review draws together research informing the scope and effectiveness of health promotion programs, initiatives and interventions targeting overweight and obesity in safety critical surface transport domains including the truck, bus and rail industries. A number of health interventions demonstrated measurable successes, including incentivising, peer mentoring, verbal counselling, development of personalised health profiles, and offer of healthier on-site food choices – some of which also resulted in sizeable return on investment over the long term.

    This article describes the planning, implementation, and outcomes of 2 complementary quality initiatives, bedside handoff and nurse-initiated interdisciplinary bedside rounds, in a 24-bed medical/surgical intensive care unit. Systematic approaches such as Kotter's change model and unit-based champions were used to redesign care processes and standardize daily communication and workflows. Active partnership with the patient and the family during these changes promoted a strong intensive care unit culture of patient- and family-centered care.

    To compare initial and recurrent concussions regarding average number of days between concussions, acute concussion symptoms and symptom resolution time, and return to play time. High school athletes sustaining multiple concussions linked within sport seasons drawn from a large sports injury surveillance study. Retrospective analysis of longitudinal surveillance data. Number of days between concussions, number of symptoms endorsed, specific symptoms endorsed, symptom resolution time, return to play time. Median time between initial and recurrent concussions was 21 days (interquartile range = 10-43 days). Loss of consciousness, the only significant symptom difference, occurred more frequently in recurrent (6.8%) than initial (1.7%) concussions (P = .04). No significant difference was found in the number of symptoms (P = .84) or symptom resolution time (P = .74). Recurrent concussions kept athletes from play longer than initial concussions (P concussions were season ending. We found that athletes' initial and recurrent concussions had similar symptom presentations and resolution time. Despite these similarities, athletes were restricted from returning to play for longer periods following a recurrent concussion, indicating clinicians are managing recurrent concussions more conservatively. It is probable that concussion recognition and management are superior now compared with when previous studies were published, possibly improving recurrent concussion outcomes.

    2017-01-01

    Full Text Available This study examines how perceptions of the legitimacy of university sustainability efforts—support by the administration (authorization or from students’ peers (endorsement—as well as the physical context in which students live, matter in shaping students’ environmentally responsible behaviors (ERBs. Using survey data collected from fourth-year students at a university in the Southeastern US, we employ Seeming Unrelated Regression to analyze the impact of perceived legitimacy and context on recycling and conservation behaviors, controlling for demographic characteristics, pro-environmental attitudes, and environmental identity. Our findings indicate that students’ perceptions of what university administrators support affect the likelihood of students to enact recycling and conservation behaviors, and peer support influences conservation behaviors. This research contributes to the literature on legitimacy by examining how legitimacy processes work in natural, rather than experimental, settings.

    2017-12-07

    In recent decades, evidence-based practices (EBPs) have been broadly promoted in community behavioural health systems in the United States of America, yet reported EBP penetration rates remain low. Determining how to systematically sustain EBPs in complex, multi-level service systems has important implications for public health. This study examined factors impacting the sustainability of parent-child interaction therapy (PCIT) in large-scale initiatives in order to identify potential predictors of sustainment. A mixed-methods approach to data collection was used. Qualitative interviews and quantitative surveys examining sustainability processes and outcomes were completed by participants from 12 large-scale initiatives. Sustainment strategies fell into nine categories, including infrastructure, training, marketing, integration and building partnerships. Strategies involving integration of PCIT into existing practices and quality monitoring predicted sustainment, while financing also emerged as a key factor. The reported factors and strategies impacting sustainability varied across initiatives; however, integration into existing practices, monitoring quality and financing appear central to high levels of sustainability of PCIT in community-based systems. More detailed examination of the progression of specific activities related to these strategies may aide in identifying priorities to include in strategic planning of future large-scale initiatives.

    This paper places focus on explicit consideration of sustainability issues in transport decision making by presenting and using a developed “Decision Simulation Technique” (DST). This technique can be used by an analyst to ‘scan’ a transport planning problem with regard to what in DST terms...... the DST can indicate which one from the set of alternatives will in fact be the ‘best’ seen from the viewpoint of a sustainability strategy, before they are all scrutinised by the decision makers. The paper consists of three parts. The first part describes the various concepts and elements of the DST...... together with the principal steps that have to be followed when applying it on a concrete case. In the second part the potential of the DST is demonstrated by its use within an ongoing study. Thus the DST is applied on a new rail investment study on a section with four alternatives being part of a proposed...

  11. Predicting uncertainty in sediment transport and landscape evolution - the influence of initial surface conditions

    Science.gov (United States)

    Hancock, G. R.; Coulthard, T. J.; Lowry, J. B. C.

    2016-05-01

    Numerical landscape evolution models were initially developed to examine natural catchment hydrology and geomorphology and have become a common tool to examine geomorphic behaviour over a range of time and space scales. These models all use a digital elevation model (DEM) as a representation of the landscape surface and a significant issue is the quality and resolution of this surface. Here we focus on how subtle perturbations or roughness on the DEM surface can produce alternative model results. This study is carried out by randomly varying the elevations of the DEM surface and examining the effect on sediment transport rates and geomorphology for a proposed rehabilitation design for a post-mining landscape using multiple landscape realisations with increasing magnitudes of random changes. We show that an increasing magnitude of random surface variability does not appear to have any significant effect on sediment transport over millennial time scales. However, the random surface variability greatly changes the temporal pattern or delivery of sediment output. A significant finding is that all simulations at the end of the 10,000 year modelled period are geomorphologically similar and present a geomorphological equifinality. However, the individual patterns of erosion and deposition were different for repeat simulations with a different sequence of random perturbations. The alternative positions of random perturbations strongly influence local patterns of hillslope erosion and evolution together with the pattern and behaviour of deposition. The findings demonstrate the complex feedbacks that occur even within a simple modelled system.

    2016-04-01

    Full Text Available This paper is a comprehensive coverage of a research project of the National Priority Research Program of the Qatar National Research Fund, entitled ‘Investigating the Qualities of the Urban Environment in Emerging Regional Metropolises’, and carried out between 2011 and 2014 through the joint collaboration of Qatar University and Technische Universität München. Through the shift of global economic forces Gulf cities, such as Qatar’s capital Doha, are developed as central hubs between developed economies in the West and the rising economies of Asia. In the context of international competition between cities new challenges are emerging where cities need to find ways to sustain and extend their position in a globalizing world. Therefore the research process placed emphasis on the complex interrelationship of knowledge economies and spatial developments in the Gulf region. The work is premised on the assumption that non-physical economic aspects and the qualities of the urban environment are interdependent. It analyses the qualities of the urban environment of Doha as an important regional metropolis through a comprehensive investigation utilizing a set of interdisciplinary research methods that include analysis of historic documents, Delphi interview series, company network analysis, GIS analysis, cognitive mapping, behavioural studies, media surveys, attitude surveys, and space syntax analysis. The outcomes promise important results regarding urban qualities in the city of Doha culminating into various recommendations aimed at potential beneficiaries including public sector organizations, private sector and real estate development companies, and academia.

    GenPhilly is an innovative, replicable model that was developed in Philadelphia, Pennsylvania, to inspire and engage emerging leaders from a variety of disciplines to promote and sustain an aging-in-community agenda. Administrative support is provided by the Area Agency on Aging, Philadelphia Corporation for Aging, yet it was designed by its members to be peer-led. In this way, young professionals in their 20s and 30s can capitalize on popular culture to create unique professional development opportunities and get younger generations thinking about the type of city in which they themselves want to get older. The group has benefited the field of aging by building awareness of aging services in the wider community; facilitating cross-disciplinary learning and innovation around aging issues; stressing the competitive advantage for emerging leaders from all fields to know about aging issues; strengthening the aging network workforce; breaking down stereotypes about working with older adults; and introducing expertise from outside the aging network to benefit older adults. Encouraging the development of similar groups will not only benefit the field of aging, it will assist the next generation of leaders in many fields to plan better for their communities and for themselves.

    This study aims to explore to what extent the principles of sustainability have been applied in a tapioca industry located in Lake Toba area and to explore the aspects that open the opportunities for system improvement. In conducting such assessment, we adopted the life-cycle approach using Mass Flow Analysis methods that covers all cassava starch production processes from fresh cassava root till dry cassava starch. The inventory data were collected from the company, in the form of both production record and interviews. From data analysis the authors were able to present a linked flow that describes the production process of tapioca starch that quantifies into the functional unit of one pack marketable tapioca starch weighs 50 kg. In order to produce 50 kg of tapioca, 200 kg cassava root and 800 kg of water are required. This production efficiency translates to 25% yield. This system generates 40 kg of cassava peel, 60 kg of pulp and 850 kg of waste water. For starch drying 208.8 MJ of thermal energy is required in the form of heating fuel. The material flow analysis is employed for impact assessment. Several options in improving the operation are proposed includes utilization of pulp into more valuable co-products, integration of waste treatment plant to enable the use of water recycled from the extraction operation for the washing process, and to application of a waste water treatment system that produces biogas as a renewable energy, which reduces the consumption of fuel in dryer unit.

    2018-02-01

    Full Text Available Innovative solutions have been implemented to promote sustainable mobility in urban areas. In the Nantes area (northwestern part of France, alternatives to single-occupant car use have increased in the past few years. In the urban area, there is an efficient public transport supply, including tramways and a “busway” (Bus Rapid Transit, as well as bike-sharing services. In periurban and rural areas, there are carpool areas, regional buses and the new “tram-train” lines. In this article, we focus on the impact on house prices of these “sustainable” transportation infrastructures and policies, in order to evaluate their values. The implicit price of these sustainable transport offers was estimated through hedonic price functions describing the Nantes urban and periurban/rural housing markets. Spatial regression models (SAR, SEM, SDM and GWR were carried out to capture the effect of both spatial autocorrelation and spatial heterogeneity. The results show patterns of spatial heterogeneity of transportation offer implicit prices at two scales: (i between urban and periurban/rural areas, as well as (ii within each territory. In the urban area, the distance to such offers was significantly associated with house prices. These associations varied by type of transportation system (positive for tramway and railway stations and negative for bike-sharing stations. In periurban and rural areas, having a carpool area in a 1500-m buffer around the home was negatively associated with house prices, while having a regional bus station in a 500-m buffer was non-significant. Distance to the nearest railway station was negatively associated with house prices. These findings provide research avenues to help public policy-makers promote sustainable mobility and pave the way for more locally targeted interventions.

    Matsutake mushrooms are an important part of rural livelihoods and forest ecosystems across large parts of China, as well as elsewhere in East Asia, Northern Europe and North America. Mushroom harvesters have developed sophisticated understandings of matsutake ecology and production, and are applying this knowledge in various innovative management strategies. At the same time, Chinese government agencies and scientists are promoting matsutake-based livelihoods to support development and conservation goals. We collaborated with matsutake harvesters in one Yunnan community to carry out a systematic experiment on a popular shiro-level management technique: covering matsutake shiros with either plastic or leaf litter. Our experimental results suggest that although leaf litter coverings are superior to plastic coverings, shiros that are left uncovered may produce the highest yields. Complementing our experimental work is a multi-sited household survey of existing matsutake management practices across Yunnan, which shows that a high proportion of harvesters are already engaged in a broad range of potentially beneficial management strategies. Though both findings highlight limitations of previous initiatives led by government and research actors in China, this existing body of work is an important foundation and opportunity for developing applied mycology in the region. In and beyond China, working with communities to develop site-specific management strategies through rigorous and participatory scientific inquiry can provide salient benefits for both scientists and resource users.

    Small-scale pilot projects have demonstrated that integrated population, health and environment approaches can address the needs and rights of vulnerable communities. However, these and other types of health and development projects have rarely gone on to influence larger policy and programme development. ExpandNet, a network of health professionals working on scaling up, argues this is because projects are often not designed with future sustainability and scaling up in mind. Developing and implementing sustainable interventions that can be applied on a larger scale requires a different mindset and new approaches to small-scale/pilot testing. This paper shows how this new approach is being applied and the initial lessons from its use in the Health of People and Environment in the Lake Victoria Basin Project currently underway in Uganda and Kenya. Specific lessons that are emerging are: 1) ongoing, meaningful stakeholder engagement has significantly shaped the design and implementation, 2) multi-sectoral projects are complex and striving for simplicity in the interventins is challenging, and 3) projects that address a sharply felt need experience substantial pressure for scale up, even before their effectiveness is established. Implicit in this paper is the recommendation that other projects would also benefit from applying a scale-up perspective from the outset. Copyright © 2014 Reproductive Health Matters.

    2018-03-01

    Full Text Available This study has two main purposes. First, it explores the performance indicators disclosed in the Global Reporting Initiative (GRI-based Sustainability Reports (SRs produced by the companies of three different countries: Italy, Spain and Greece. Second, it verifies how some corporate variables, country of origin variables and “attributes” of the SRs can explain the disclosure of GRI indicators. To verify the quantity and type of the indicators disclosed, we performed a content analysis of the SRs. We use a regression trees technique to describe how the companies’ variables explain a different use of the indicators. The findings show that Spanish companies, on average, disclose the greatest number of indicators. The social indicators related to Labour are those more frequently reported in the SRs of the three countries. The least reported are social indicators related to Human Rights. The results show the central role that assurance, ROA and sector may have in classifying the disclosure level of indicators. The study contributes both theoretical and empirical literature on sustainability indicators. It also sheds further light on the determinants of the disclosure of indicators.

    2006-12-01

    Recently, an interdisciplinary group of faculty from the University of Idaho was awarded a major internal grant for their project "Water of the West (WoW)" to launch an interdisciplinary Water Resources Graduate Education Program. This Water Resources program will facilitate research and education to influence both the scientific understanding of the resource and how it is managed, and advance the decision-making processes that are the means to address competing societal values. By educating students to integrate environmental sciences, socio-economic, and political issues, the WoW project advances the University's land grant mission to promote economic and social development in the state of Idaho. This will be accomplished through novel experiential interdisciplinary education activities; creation of interdisciplinary research efforts among water resources faculty; and focusing on urgent regional problems with an approach that will involve and provide information to local communities. The Water Resources Program will integrate physical and biological sciences, social science, law, policy and engineering to address problems associated with stewardship of our scarce water resources. As part of the WoW project, faculty will: (1) develop an integrative problem-solving framework; (2) develop activities to broaden WR education; (3) collaborate with the College of Law to offer a concurrent J.D. degree, (4) develop a virtual system of watersheds for teaching and research, and (5) attract graduate students for team-based education. The new program involves 50 faculty from six colleges and thirteen departments across the university. This university-wide initiative is strengthened by collaboration with the Idaho Water Resources Research Institute, and participation from off-campus Centers in Idaho Falls, Boise, Twin Falls, and Coeur d'Alene. We hope this presentation will attract university faculty, water resources professionals, and others for stimulating discussions on

  6. THE ANALYSIS OF SEVERAL RESULTS OBTAINED BY ROMANIA IN THE FIELD OF SUSTAINABLE TRANSPORT

    Directory of Open Access Journals (Sweden)

    Perțicaș Diana Claudia

    2015-07-01

    Full Text Available We know that between the transport sector and all other branches of economy there is a strong interdependence link but also between it and the surrounding environment, being one of the most polluting sectors of activity. Transport is considered a primary field in any national economy development context, especially if we take into account its interdependence with other branches of national economy. Developing of transports also includes improving road, rail, river and sea services, as well as air transports. The objectives of the EU aim especially to modernize the transport infrastructures, be them by road, ship or by air, which would result in increasing the speed of freight transport, fluidizing traffic, attracting new foreign investors in various areas, accelerating the renewal of the auto park and decommissioning morally and physically worn vehicles which are extremely pollutant, the revival of maritime transports through Romanian ports, progressive completion of imposed performances through standards and regulations on the transport market, etc. All these objectives have as a main purpose the reducing of energy consumption, reducing transport costs as well as increasing competition in the national transport system.The development of transport has the role of stimulating public transport services and to guarantee a minimum general accessibility to public services for all citizens. Children, the elderly, disabled people or other vulnerable categories of people are not and will not be forgotten, for which certain standards set by the European Union must be respected.The present paper wishes to analyze a part of the results, either positive or negative, in the field of transports, made by our country.

  10. Measuring buildings for sustainability: Comparing the initial and retrofit ecological footprint of a century home – The REEP House

    International Nuclear Information System (INIS)

    Bin, Guoshu; Parker, Paul

    2012-01-01

    Highlights: ► Life cycle energy, carbon and ecological footprints of a century home are studied. ► The operational impact accounts for most of the total lifecycle impact. ► Sourcing energy-intensive materials locally only reduces embodied impacts a little. ► Deep energy retrofits (80% savings) achieved substantial environmental benefits. ► The environmental payback period of major energy retrofits is less than 2 years. - Abstract: The residential sector is recognized as a major energy consumer and thus a significant contributor to climate change. Rather than focus only on current energy consumption and the associated emissions, there is a need to broaden sustainability research to include full life cycle contributions and impacts. This paper looks at houses from the perspective of the ecological footprint (EF), a well-known sustainability indicator. Exemplifying single-detached houses of the early 20th century, the century-old REEP House (downtown Kitchener, Canada), together with its high performance energy retrofits, is examined in detail. This research combines material, energy and carbon emission studies. Its scope covers the life cycle of the house, including the direct and indirect consumption of material and energy, and concomitant carbon emissions during its stages of material extraction, transportation, construction, operation, and demolition. It is revealed that the REEP House had a typical impact on the environment when it was built, and, even though the renovations to improve energy efficiency by 80% introduce additional embodied environmental impacts, they are environmentally sound activities because the environmental payback period is less than 2 years.

    To profile the initial clinical events of glucose transporter 1 deficiency syndrome (Glut1 DS) in order to facilitate the earliest possible diagnosis. We retrospectively reviewed 133 patients with Glut1 DS from a single institution. Family interviews and medical record reviews identified the first clinical event(s) reported by the caregivers. Average age of the first event was 8.15 ± 11.9 months (range: 0.01-81). Ninety-one patients experienced the first symptom before age 6 months (68%). Thirty-three additional patients (25%) presented before age 2 years. Only 9 patients (7%), reported the first event after age 2 years. Seizures were the most common first event (n = 81, 61%), followed by eye movement abnormalities (n = 51, 38%) and changes in muscle strength and tone (n = 30, 22%). Eye movement abnormalities, lower cerebrospinal fluid glucose values, and lower Columbia Neurological Scores correlated with earlier onset of the first event (r: -0.17, 0.22, and 0.25 respectively, P < .05). There was no correlation with age of first event and red blood cell glucose uptake or mutation type. Glut1 DS is a treatable cause of infantile onset encephalopathy. Health care providers should recognize the wide spectrum of paroxysmal events that herald the clinical onset of Glut1 DS in early infancy to facilitate prompt diagnosis, immediate treatment, and improved long-term outcome.

    Full text: Regulatory inspection and law enforcement are among the core competencies of the Indonesia Nuclear Energy Regulatory Agency (BAPETEN). Knowledge management (KM) initiatives are based on strategic planning of BAPETEN. KM in BAPETEN is in its early stage, it is realized since 2015–2016, although its elements have stayed in service for 18 years. Its architecture and performance-information are: to conduct risk based inspection for medical, industrial and research facilities; to plan, monitor and evaluate of effective inspection, including standard operating procedures (SOPs); to utilize inspectors for safety security of radiation sources along with coordination with related stakeholders; to enforce the safety and security facilities report to users; to optimize reliable data communication, processing and information technology (B@LIS); to perform regulatory enforcement along with other related stakeholders. KM processes are performed through the “Socialization, Externalization, Combination, Internalization” (SECI) model. Technical knowledge for inspectors are based on the IAEA–TECDOC–1526 plus supporting knowledge. With KM, innovation products can easily be used, because they are documented, distributed in a KM portal, knowledge is shared through the BAPETEN website, B@LIS database and others. Our challenge is that KM initiatives still need a tremendous effort, not only internally, but also externally, especially in coordination and collaboration. Information access brings about not only positive but also negative impacts. Innovations in regulatory inspection and law enforcement in BAPETEN are planned innovations, sustained, and systematically performed. (author

  13. Analysis of transport eco-efficiency scenarios to support sustainability assessment: a study on Dhaka City, Bangladesh.

    The study focused to assess the level of efficiency (of both emissions and service quality) that can be achieved for the transport system in Dhaka City, Bangladesh. The assessment technique attempted to quantify the extent of eco-efficiency achievable for the system modifications due to planning or strategy. The eco-efficiency analysis was facilitated with a detailed survey data on Dhaka City transport system, which was conducted for 9 months in 2012-2013. Line source modelling (CALINE4) was incorporated to estimate the on-road emission concentration. The eco-efficiency of the transport systems was assessed with the 'multi-criteria analysis' (MCA) technique that enabled the valuation of systems' qualitative and quantitative parameters. As per the analysis, driving indiscipline on road can alone promise about 47% reductions in emissions, which along with the number of private vehicles were the important stressors that restrict achieving eco-efficiency in Dhaka City. Detailed analysis of the transport system together with the potential transport system scenarios can offer a checklist to the policy makers enabling to identify the possible actions needed that can offer greater services to the dwellers against lesser emissions, which in turn can bring sustainability of the system.

    Hayes, Christopher William; Goldmann, Don

    2018-03-01

    Failure to consider the impact of change on health care providers is a barrier to success. Initiatives that increase workload and have low perceived value are less likely to be adopted. A practical model and supporting tools were developed on the basis of existing theories to help quality improvement (QI) programs design more adoptable approaches. Models and theories from the diffusion of innovation and work stress literature were reviewed, and key-informant interviews and site visits were conducted to develop a draft Highly Adoptable Improvement (HAI) Model. A list of candidate factors considered for inclusion in the draft model was presented to an expert panel. A modified Delphi process was used to narrow the list of factors into main themes and refine the model. The resulting model and supporting tools were pilot tested by 16 improvement advisors for face validity and usability. The HAI Model depicts how workload and perceived value influence adoptability of QI initiatives. The supporting tools include an assessment guide and suggested actions that QI programs can use to help design interventions that are likely to be adopted. Improvement advisors reported good face validity and usability and found that the model and the supporting tools helped address key issues related to adoption and reported that they would continue to use them. The HAI Model addresses important issues regarding workload and perceived value of improvement initiatives. Pilot testing suggests that the model and supporting tools are helpful and practical in guiding design and implementation of adoptable and sustainable QI interventions.

    NREL Analysis Insights mines our body of analysis work to synthesize topical insights and key findings. In this issue, we examine transportation systems, alternative fuels, and implications of increasing electrification of transit. Moving people and goods from point A to B has never been easier, but our current transportation systems also take a toll on our environment. Transportation currently accounts for 71% of total U.S. petroleum use and 33% of the nation’s total carbon emissions. With new technology, can we make our transportation system cleaner and more cost effective? NREL is applying its analytical expertise and imagination to do just that. Solutions start with systems thinking. Connecting the dots between physical components - vehicles, fueling stations, and highways - and institutional components - traffic laws, regulations, and vehicle standards - helps illuminate solutions that address the needs of the transportation system's many stakeholders.

    2017-06-01

    The article explains the role of public transport pricing. It proves the need for a systemic approach to building a modern public transit system. The authors argue that the main objective of the approach should be to reduce the use of private vehicles in the urban environment and increasing public transport use. It is proven that for the consumer of transport services the price per trip is an important factor when deciding whether to travel by car or by public transport. The authors analyze the available literature assessing the effects of widespread car ownership on users of the city transit system. Conflict situations that occur due to the unabated desire of city residents to travel by car are analyzed. A research method is proposed. It is shown that public transport fares have been growing in Russia at an accelerated pace when compared to the overall increase in prices of all goods and services, including motor vehicles, petrol and oils. The fare growth has resulted in a 3.6 fold drop in demand for public transport services over the 15 years being analyzed. Over the same period, the number of privately owned cars grew 120 percent. A conclusion is drawn that regular fare hikes have encouraged urban population to gradually opt against travelling by public transport. That resulted in higher demand for car travel and, eventually, in an accelerated growth in car usage. One can conclude that a persistent institutional trap has taken shape in Russian metropolises. Essentially, it means that higher public transport fares have led to lower demand for public transit services. As ridership goes down, public transport operators have to again increase prices, thus driving the demand for their services down. It is proven that escaping the trap will require restoring the ratio of prices to make sure that the price charged for a public transport trip is far lower than the cost of travelling by car. The aim of this study is to assess the influence of the factor of public

  4. Initial Energy Logistics Cost Analysis for Stationary, Quasi-Dynamic, and Dynamic Wireless Charging Public Transportation Systems

    Directory of Open Access Journals (Sweden)

    Young Jae Jang

    2016-06-01

    Full Text Available This paper presents an initial investment cost analysis of public transportation systems operating with wireless charging electric vehicles (EVs. There are three different types of wireless charging systems, namely, stationary wireless charging (SWC, in which charging happens only when the vehicle is parked or idle, quasi-dynamic wireless charging (QWC, in which power is transferred when a vehicle is moving slowly or in stop-and-go mode, and dynamic wireless charging (DWC, in which power can be supplied even when the vehicle is in motion. This analysis compares the initial investment costs for these three types of charging systems for a wireless charging-based public transportation system. In particular, this analysis is focused on the energy logistics cost in transportation, which is defined as the cost of transferring and storing the energy needed to operate the transportation system. Performing this initial investment analysis is complicated, because it involves considerable tradeoffs between the costs of batteries in the EV fleet and different kinds of battery-charging infrastructure. Mathematical optimization models for each type of EV and infrastructure system are used to analyze the initial costs. The optimization methods evaluate the minimum initial investment needed to deploy the public transportation system for each type of EV charging solution. To deal with the variable cost estimates for batteries and infrastructure equipment in the current market, a cost-sensitivity analysis is performed. The goal of this analysis is to identify the market cost conditions that are most favorable for each type of wireless charging solution. Furthermore, the cost analysis quantitatively verifies the qualitative comparison of the three different wireless charging types conducted in the previous research.

    It is said that the car is convenient but consumes high-energy per passenger, while public transport is an environmentally friendly mode but needs high cost of investment and management. However, this view does not take account of urban structure such as population size and density. For instance, higher population density would cause congestion and consequent inconvenience for car usage. This may shift demand to public transport use. On the other hand, in a lower density of urban area, public...

  12. The Importance of the United Nations Guidelines for the Long-Term Sustainability of Space Activities and Other International Initiatives to Promote Space Sustainability

    Directory of Open Access Journals (Sweden)

    Laura Delgado López

    2014-12-01

    Full Text Available The long-term sustainability of space activities is an emerging issue to which actors in the global space community –including governments, agencies, and industry– are devoting increasing amounts of attention and resources. Considering the sustainability of space activities involves taking into account the present population of space debris, the size of the debris population in the most commonly-used Earth orbits in the future, and the possibility of collision events between objects in space. Addressing space debris and other threats to space sustainability involves both technological and political solutions. The United Nations Committee on the Peaceful Uses of Outer Space (copuos has led a major effort to define such solutions and has established a working group tasked with the development of non-binding long-term sustainability (lts guidelines. This article includes an overview of the concept of space sustainability, a discussion of the need, development, and current status of the lts guidelines, as well as an analysis of some of the guidelines themselves. It concludes with a broader discussion of space as an area without state sovereignty – one of the key aspects that have influenced the development of non-binding measures to address the space sustainability challenge. In this context, and given the governance questions that arise from the interaction between states and non-state actors in this domain, this discussion should be of interest to international relations scholars and practitioners.

    The presented results are based on the experimental studies of generating a long plasma column in gas (or gas mixtures) at atmospheric pressure both in free space and in a closed chamber. The microwave generator GYROTRON was used as an energy source. Its parameters were as follows: the microwave pulse power was in the range of 200 ≤ P ≤ 600 kW, the wavelength was λ ≈ 0.4 cm, and the pulse duration was in the range of 0.5 ≤ τi ≤ 20 ms. Under strong subthreshold conditions, a plasma column with a length of up to L ≤ 50 cm was created using a microwave beam that was formed using a quasi-optical mirror system. The discharge initiation system had an original design. Based on the discharge structure, expansion dynamics and typical discharge plasma parameters, this discharge can be attributed to the type of microwave discharges that are known as self/non-self-sustained discharges. The discharge properties and advantages of using this discharge as a basis of a plasma-chemical reactor are discussed.

    IAEA 's education and training activities in radiation, transport and waste safety follow the IAEA vision, strategy and resolutions of its annual General Conferences and reflect the latest IAEA standards and guidance. IAEA prepared a Strategic Approach to Education and Training in Radiation and Waste Safety (Strategy on Education and Training) aiming at establishing, by 2010, sustainable education and training programmes in Member States, which was endorsed by the GC(45)/RES/10C in 2001. In implementing the strategy, IAEA is organising training events at the regional level and assisting the Member States at the national level by providing them the exemplary quality of training material developed at the IAEA. This work will continue ensuring its completeness in all areas of radiation safety. An Inter Centre Network between the Agency and regional, collaborating national training centres is established to facilitate information exchange, improve communication and dissemination of training material. There is a challenge to enhance the technical capability of the Member States to reach sustainability. This is intended through organising number of Train the Trainers events to develop a pool of qualified trainers. The new developments include establishing E-learning, developing a syllabus for training of Radiation Protection Officers and training materials, information materials for radiation workers. These are aimed at assisting Member States attain self sustainability. (author)

    2013-01-01

    Full Text Available Objective. To review experience of the transport and stabilization of infants with CDH who were treated with high frequency jet ventilation (HFJV. Study Design. Retrospective chart review was performed of infants with antenatal diagnosis of CDH born between 2004 and 2009, at Mount Sinai Hospital Toronto, Ontario, Canada. Detailed information was abstracted from the charts of all infants who received HFJV. Results. Of the 55 infants, 25 were managed with HFJV at some point during resuscitation and stabilization prior to transport. HFJV was the initial ventilation mode in six cases and nineteen infants were placed on HFJV as rescue therapy. Blood gases procured from the umbilical artery before and/or after the initiation of HFJV. There was a significant difference detected for both PaCO2 (P=0.0002 and pH (P<0.0001. The pre- and posttransport vital signs remained stable and no transport related deaths or significant complications occurred. Conclusion. HFJV appears to be safe and effective providing high frequency rescue therapy for infants with CDH failing conventional mechanical ventilation. This paper supports the decision to utilize HFJV as it likely contributed to safe transport of many infants that would not otherwise have tolerated transport to a surgical centre.

    Dependence of the regional economic development from efficiency of financing of the construction of transport infrastructure is analyzed and proved in this article. Effective mechanism for infrastructure projects financing, public and private partnership, is revealed and its concrete forms are formulated. Here is proposed an optimal scenario for financing for the transport infrastructure, which can lead to positive transformations in the economy. Paper considers the advantages and risks of public and private partnership for subjects of contractual relations. At that, components for the assessment of economic effect of the implementation of infrastructure projects were proposed simultaneously with formulation of conditions for minimization risks. Results of the research could be used for solution of persistent problems in the development of transport infrastructure, issues of financial assurance of construction of infrastructure projects at the regional level.

    International Nuclear Information System (INIS)

    Van Stappen, Florence; Brose, Isabelle; Schenkel, Yves

    2011-01-01

    Facing climate change and growing energy prices, the use of bioenergy is continuously increasing in order to diminish greenhouse gas emissions, secure energy supply and create employment in rural areas. Because the production of biomass or biofuels, wherever it takes place, comes along with externalities, positive or negative, the need for biomass and bioenergy sustainability criteria is more than ever felt. Research on sustainability criteria and certification systems has started through several national and international initiatives. Considering the benefits of an increased use of bioenergy but also the urge for limiting potential negative environmental and socio-economic impacts, the aim of these initiatives was to make the first move regarding bioenergy sustainability, while waiting for the European legislation to regulate this crucial issue. Land use changes, whether direct or indirect, are one of the most important consequences of bioenergy production. While direct land use changes are more easily assessed locally, indirect land use changes exceed the company level and need to be considered at a global scale. Methodologies for dealing with direct and indirect land use changes are proposed among others in the European, Dutch, British and German sustainability initiatives. This paper aims at presenting and comparing those four European initiatives, with a focus on their propositions for direct and indirect land use changes assessment. Key issues are discussed and recommendations are made for steps to overcome identified difficulties in accurately assessing the effects of indirect land use change due to bioenergy production.

    Revunova, Svetlana; Vlasenko, Vyacheslav; Bukreev, Anatoly

    2017-10-01

    The article proposes the models of innovative activity development, which is driven by the formation of “points of innovation-driven growth”. The models are based on the analysis of the current state and dynamics of innovative development of construction enterprises in the transport sector and take into account a number of essential organizational and economic changes in management. The authors substantiate implementing such development models as an organizational innovation that has a communication genesis. The use of the communication approach to the formation of “points of innovation-driven growth” allowed the authors to apply the mathematical tools of the graph theory in order to activate the innovative activity of the transport industry in the region. As a result, the authors have proposed models that allow constructing an optimal mechanism for the formation of “points of innovation-driven growth”.

  7. Analytical decision-making methods for evaluating sustainable transport in European corridors

    CERN Document Server

    2014-01-01

    Eurocorridors are characterized by intensive transport flows and dynamic patterns of establishment and household locations. They are also considered the backbones of powerful spatial and economic forces in the areas that connect urban regions. One of the main difficulties in the spatial planning of eurocorridors has been the need to engage in different types of collective action. Such an approach can be extremely challenging in practice, useful to researchers in the field and to professionals as well. In the light of this, the book’s main objectives are:  - To define the problem by analyzing the key features, which include freight and passenger transport policies and issues; the territorial context, with its geographical, social, economic and cultural aspects; the plurality of subjects with different aims and resources and the lack of homogeneous information. - To illustrate assessment models and evaluation frameworks (MCDA; Discrete Choice Analysis; Collaborative Assessments; Geovisualization Technologi...

    2011-07-01

    While it is increasingly popular to broadcast information regarding environmental impact, little is known regarding the effects that this information has on human behavior. This research aims to provide insight into whether, and to what extent, presenting environmental attributes of transport alternatives influences individual transport decisions. We designed and conducted three experiments in which subjects (UC Berkeley undergraduates) were presented with hypothetical scenarios of transport decisions, including auto purchase choice, mode choice, and route choice. We analyzed their decisions via a choice model to determine how they value reducing their emissions relative to other attributes. We found that our subjects are willing to adjust their behavior to reduce emissions, exhibiting an average willingness to pay for emissions reduction, or value of green (VoG), of 15 cents per pound of CO2 saved. Despite concern that people cannot meaningfully process quantities of CO2, we found evidence to the contrary in our subject pool in that the estimated VoG was consistent across context (the wide range of transport decisions that we presented) and presentation (e.g., whether the information was presented in tons or pounds, or whether a social reference point of the emissions of an average person was provided). We also found significant heterogeneity in VoG, with most of the respondents valuing green somewhere between 0 and 70 cents per pound and with women, on average, willing to pay 7 cents more per saved pound than men. While the findings are encouraging, further work is required to determine whether they hold outside of a lab environment and with a more representative pool of subjects.

    Climate change is a problem that must be solved. The primary cause of this problem is burning of fossil fuels to generate energy. A dramatic reduction in carbon emissions must happen soon, and a significant fraction of this reduction must come from the transportation sector. This paper reviews existing literature to assess the consensus of the scientific and engineering communities concerning the potential for the United States' light-duty transportation sector to meet a goal of 80 percent reduction in vehicle emissions and examine what it will take to meet this target. It is unlikely that reducing energy consumption in just vehicles with gasoline-based internal combustion drivetrains will be sufficient to meet GHG emission-reduction targets. This paper explores what additional benefits are possible through the adoption of alternative energy sources, looking at three possible on-vehicle energy carriers: carbon-based fuels, hydrogen, and batteries. potential for the United States' light-duty transportation sector to meet a goal of 80 percent reduction in vehicle emissions and examine what it will take to meet this target.

    Potassium (K) and phosphate (Pi) are both macronutrients essential for plant growth and crop production, but the unrenewable resources of phosphorus rock and potash have become limiting factors for food security. One critical measure to help solve this problem is to improve nutrient use efficiency (NUE) in plants by understanding and engineering genetic networks for ion uptake, translocation, and storage. Plants have evolved multiple systems to adapt to various nutrient conditions for growth and production. Within the NUE networks, transport proteins and their regulators are the primary players for maintaining nutrient homeostasis and could be utilized to engineer high NUE traits in crop plants. A large number of publications have detailed K+ and Pi transport proteins in plants over the past three decades. Meanwhile, the discovery and validation of their regulatory mechanisms are fast-track topics for research. Here, we provide an overview of K+ and Pi transport proteins and their regulatory mechanisms, which participate in the uptake, translocation, storage, and recycling of these nutrients in plants. © The Author 2016.

    Full Text Available The need for reduction in power consumption for public facilities has increased after the occurrences of multiple blackout events. In an effort to enable the development of green and smart social infrastructure, this paper introduces a design for a sustainable and efficient transportation system (SETS. For this design, renewable power sources and efficient electric drives are considered to be crucial technologies. Considering the subway station as an illustrative example, a power system design that uses wind and solar energy as major power sources is studied. The adjustable speed electric drive system that uses synchronous reluctance machines for ventilation systems contributes to increasing the overall power consumption efficiency. The effectiveness of the proposed SETS system is verified through a set of various field measurement data and simulation results. While the verification results demonstrate that operation of SETS is enabled by effective integration of renewable sources and efficient ventilation systems, future research directions have also been identified.

    As a major part of farming sustainability, the issues of grain production and its quality improvement have been important in many countries. This paper aims to address these issues in China. Based on the data from the main production provinces and by applying the stochastic frontier analysis methodology, we find that the improvement of transportation and the use of agricultural machinery have become the main driving forces for grain quality improvement in China. After further studying different provinces' potentials of grain quality improvement, we show that grain quality has increased steadily. Therefore, we can conclude China's grain quality improvement is indeed sustainable. Furthermore, different grains like rice, wheat, and corn share similar characteristics in terms of quality improvement, but the improvement rate for rice is relatively low, while those of corn and wheat are relatively high. Moreover, the overall change of efficiency gain of grain quality improvement is not significant for different provinces. The efficiency gains of the quality improvements for rice and wheat even decrease slightly. In addition, we find that only expanding grain quality improvement potential can simultaneously achieve the dual objectives of improving grain quality and increasing yield.

    A necessary prerequisite of cloud formation, aerosol particles represent one of the largest uncertainties in computer simulations of climate change1,2, in part because of a poor understanding of processes under natural conditions3,4. The Amazon rainforest is one of the few continental regions where aerosol particles and their precursors can be studied under near-natural conditions5-7. Cloud condensation nuclei (CCN) in clean Amazonia are mostly produced by the growth of smaller particles in the boundary layer8-10, whereas these smaller particles themselves 31 appear to be produced elsewhere5,11. Key questions are in what part of the atmosphere they might 32 be produced and what could be the transport processes that deliver them to the boundary layer, where they grow into CCN. Here, using recent aircraft measurements above central Amazonia, we show high concentrations of small particles in the lower free troposphere. The particle size spectrum shifts towards larger sizes with decreasing altitude, implying particle growth as air descends from the free troposphere towards Earth's surface. Complementary measurements at ground sites show that free tropospheric air having high concentrations of small particles (diameters of less than 50 nm) is transported into the boundary layer during precipitation events, both by strong convective downdrafts and by weaker downward motions in the trailing stratiform region. This vertical transport helps maintain the population of small particles and ultimately CCN in the boundary layer, thereby playing an important role in controlling the climate state under natural conditions. In contrast, this mechanism becomes masked under polluted conditions, which sometimes prevail at times in Amazonia as well as over other tropical continental regions5,12.

    Ultraclean fuels production has become increasingly important as a method to help decrease emissions and allow the introduction of alternative feed stocks for transportation fuels. Established methods, such as Fischer-Tropsch, have seen a resurgence of interest as natural gas prices drop and existing petroleum resources require more intensive clean-up and purification to meet stringent environmental standards. This review covers some of the advances in deep desulfurization, synthesis gas conversion into fuels and feed stocks that were presented at the 245th American Chemical Society Spring Annual Meeting in New Orleans, LA in the Division of Energy and Fuels symposium on "Ultraclean Fuels Production and Utilization".

    This paper reports the estimation of transportation energy consumption based on the travel behaviour characteristics of the population in the Engineering Campus, Universiti Sains Malaysia. The travel behaviour characteristics include the travel distance, travel speed, number of trips per day, and modal share of the transport, which only focused on the trips that were made inside the campus. The travel behaviour data were collected through online and pencil-and-paper questionnaire survey involving 1000 respondents including staffs and students, which is equivalent to 25% of the total population. The result from the survey showed that a total of 1897 trips per day were made by the motorised vehicle owners including car and motorcycle owners. The total trip length per day was 1056.29 km with an average speed of 45km/h. The average trip for each person was four trips per day. The estimate energy consumption from the motorised vehicles in this campus was reported to be 1.25E9 MJ.

    2014-08-28

    Lipid-based lyotropic liquid crystals, also referred to as reversed liquid crystalline mesophases, such as bicontinuous cubic, hexagonal or micellar cubic phases, have attracted deep interest in the last few decades due to the possibility of observing these systems at thermodynamic equilibrium in excess water conditions. This becomes of immediate significance for applications in the colloidal environment, such as in the food, cosmetic and pharmaceutical arenas. One possible application regarded as very promising is that of controlled delivery of functional ingredients. Different crystallographic structures of the lipid mesophase give access to different diffusion coefficients and distinct diffusion modes. It becomes thus crucial to engineer the space group of the mesophase in a controlled way, and ideally, in a stimuli-responsive manner. In this article we review the state of the art on diffusion and molecular transport in lipid-based mesophases and we discuss recent contributions to the controlled delivery of molecules and colloids through these systems. In particular we focus on the different available strategies relying on either endogenous or exogenous stimuli to induce changes in the symmetry and transport properties of lipid-based mesophases and we discuss the impact and implications this may have on controlled drug delivery.

    Full Text Available The transport sector needs to go through an extended process of decarbonisation to counter the threat of climate change. Unfortunately, the International Energy Agency forecasts an enormous growth in the number of cars and greenhouse gas emissions by 2050. Two issues can thus be identified: (1 the need for a new methodology that could evaluate the policy performances ex-ante and (2 the need for more effective policies. To help address these issues, we developed an Agent-Based Model called Mobility USA aimed at: (1 testing whether this could be an effective approach in analysing ex-ante policy implementation in the transport sector; and (2 evaluating the effects of alternative policy scenarios on commuting behaviours in the USA. Particularly, we tested the effects of two sets of policies, namely market-based and preference-change ones. The model results suggest that this type of agent-based approach will provide a useful tool for testing policy interventions and their effectiveness.

    Highlights: • Integration of carbon capture and sequestration and renewable resource technologies. • A new superstructure-based optimization model to identify the energy supply system. • Model validation via application study of the future transportation sector in Korea. - Abstract: In this study, a new design for a sustainable energy system was developed by integrating two technology frameworks: the renewable resource-based energy supply and the conventional (fossil fuel) resource-based energy production coupled with carbon capture and sequestration. To achieve this goal, a new superstructure-based optimization model was proposed using mixed-integer linear programming to identify the optimal combination of these technologies that minimizes the total daily cost, subject to various practical and logical constraints. The performance of the proposed model was validated via an application study of the future transportation sector in Korea. By considering six different scenarios that combined varying crude oil/natural gas prices and environmental regulation options, the optimal configuration of the energy supply system was identified, and the major cost drivers and their sensitivities were analyzed. It was shown that conventional resource-based energy production was preferred if crude oil and natural gas prices were low, even though environmental regulation was considered. Environmental regulation caused an increase in the total daily cost by an average of 26.4%, mainly due to CO 2 capture cost.

  4. Designing Sustainable Public Transportation: Integrated Optimization of Bus Speed and Holding Time in a Connected Vehicle Environment

    2016-11-01

    Full Text Available Developing public transportation and giving priority to buses is a feasible solution for improving the level of public transportation service, which facilitates congestion alleviation and prevention, and contributes to urban development and city sustainability. This paper presents a novel bus operation control strategy including both holding control and speed control to improve the level of service of transit systems within a connected vehicle environment. Most previous work focuses on optimization of signal timing to decrease the bus signal delay by assuming that holding control is not applied; the speed of buses is given as a constant input and the acceleration and deceleration processes of buses can be neglected. This paper explores the benefits of a bus operation control strategy to minimize the total cost, which includes bus signal delay, bus holding delay, bus travel delay, acceleration cost due to frequent stops and intense driving. A set of formulations are developed to explicitly capture the interaction between bus holding control and speed control. Experimental analysisand simulation tests have shown that the proposed integrated operational model outperforms the traditional control, speed control only, or holding control only strategies in terms of reducing the total cost of buses. The sensitivity analysis has further demonstrated the potential effectiveness of the proposed approach to be applied in a real-time bus operation control system under different levels of traffic demand, bus stop locations, and speed limits.

    Sustainable implementation of new workforce redesign initiatives requires strategies that minimize barriers and optimize supports. Such strategies could be provided by a set of guiding principles. A broad understanding of the concerns of all the key stakeholder groups is required before effective strategies and initiatives are developed. Many new workforce redesign initiatives are not underpinned by prior planning, and this threatens their uptake and sustainability. This study reports on a cross-sectional qualitative study that sought the perspectives of representatives of key stakeholders in a new workforce redesign initiative (extended-scope-of-practice physiotherapy) in one Australian tertiary hospital. The key stakeholder groups were those that had been involved in some way in the development, management, training, funding, and/or delivery of the initiative. Data were collected using semistructured questions, answered individually by interview or in writing. Responses were themed collaboratively, using descriptive analysis. Key identified themes comprised: the importance of service marketing; proactively addressing barriers; using readily understood nomenclature; demonstrating service quality and safety, monitoring adverse events, measuring health and cost outcomes; legislative issues; registration; promoting viable career pathways; developing, accrediting, and delivering a curriculum supporting physiotherapists to work outside of the usual scope; and progression from "a good idea" to established service. Health care facilities planning to implement new workforce initiatives that extend scope of usual practice should consider these issues before instigating workforce/model of care changes.

    Reducing greenhouse gas emissions (GHG) is an important social goal to mitigate climate change. A common mitigation paradigm is to consider strategy "wedges" that can be applied to different activities to achieve desired GHG reductions. In this policy analysis piece, we consider a wide range of possible strategies to reduce light-duty vehicle GHG emissions, including fuel and vehicle options, low carbon and renewable power, travel demand management and land use changes. We conclude that no one strategy will be sufficient to meet GHG emissions reduction goals to avoid climate change. However, many of these changes have positive combinatorial effects, so the best strategy is to pursue combinations of transportation GHG reduction strategies to meet reduction goals. Agencies need to broaden their agendas to incorporate such combination in their planning.

    2015-03-01

    Full Text Available In Ireland, timber and biomass haulage faces the challenge of transporting enough material within strict legal dimensions and gross vehicle weights restrictions for trucks and trailers. The objective of this study was to develop a method to control payload weight by knowing the moisture content of the wood. Weights, volumes, and moisture content were gathered from 100 truckloads of Sitka spruce pulpwood. Truck volume and weight utilization patterns were analyzed based on stacked volume, truck volume, and weights recorded from the weighbridge. Solid/bulk volume conversion factors for the truckloads were estimated indicating the truck’s solid volume capacity to be filled. Trucks were grouped into five conditions based on their configuration—volume capacity and legal maximum payload. A loaded volume fraction was estimated to assess the optimal volume capacity and stanchion height at which the trucks should be loaded. Results showed that 100% of the trucks presented volume underutilization, with a maximum of 27.5 m3 (only 39.85% volume capacity. In contrast, 67% of trucks were overweight while the remaining 33% were under the legal maximum weight. The average solid/bulk volume conversion factor was 0.66 ± 0.013 at 95% confidence level. Depending on the conditions, trucks can be filled to 100% of their volume capacity with wood at an MC from 29% to 55%. The minimum truck volume capacity utilization was 45%. This methodology can be used by truck hauliers, enabling them to determine in-forest the optimum volume and weight of wood to be transported by knowing the moisture content (MC, the wood specie, and using the height of the stanchions of the trailer as reference when loading the truck.

    The Global Modeling Initiative has integrated two 35-year simulations of an ozone recovery scenario with an offline chemistry and transport model using two different meteorological inputs. Physically based diagnostics, derived from satellite and aircraft data sets, are described and then used to evaluate the realism of temperature and transport processes in the simulations. Processes evaluated include barrier formation in the subtropics and polar regions, and extratropical wave-driven transport. Some diagnostics are especially relevant to simulation of lower stratospheric ozone, but most are applicable to any stratospheric simulation. The temperature evaluation, which is relevant to gas phase chemical reactions, showed that both sets of meteorological fields have near climatological values at all latitudes and seasons at 30 hPa and below. Both simulations showed weakness in upper stratospheric wave driving. The simulation using input from a general circulation model (GMI(sub GCM)) showed a very good residual circulation in the tropics and northern hemisphere. The simulation with input from a data assimilation system (GMI(sub DAS)) performed better in the midlatitudes than at high latitudes. Neither simulation forms a realistic barrier at the vortex edge, leading to uncertainty in the fate of ozone-depleted vortex air. Overall, tracer transport in the offline GMI(sub GCM) has greater fidelity throughout the stratosphere than the GMI(sub DAS).

    Beltramo, M. N.; Anderson, J. L.

    1977-01-01

    This paper provides a brief overview of Design to Cost (DTC). Problems inherent in attempting to estimate costs are discussed, along with techniques and types of models that have been developed to estimate aircraft costs. A set of cost estimating relationships that estimate the total production cost of commercial and military transport aircraft at the systems level is presented and the manner in which these equations might be used effectively in developing initial DTC targets is indicated. The principal point made in this paper is that, by using a disagregated set of equations to estimate transport aircraft costs at the systems level, reasonably accurate preliminary cost estimates may be achieved. These estimates may serve directly as initial DTC targets, or adjustments may be made to the estimates obtained for some of the systems to estimate the production cost impact of alternative designs or manufacturing technologies. The relative ease by which estimates may be made with this model, the flexibility it provides by being disaggregated, and the accuracy of the estimates it provides make it a unique and useful tool in establishing initial DTC targets.

    The increasing use of Sustainable Urban Drainage Systems (SUDS) for stormwater management raises some concerns about the fate of ubiquitous runoff micropollutants in soils and their potential threat to groundwater. This question may be addressed either experimentally, by sampling and analyzing SUDS soil after a given operating time, or with a modeling approach to simulate the fate and transport of contaminants. After briefly reminding the processes responsible for the retention, degradation, or leaching of several urban-sourced contaminants in soils, this paper presents the state of the art about both experimental and modeling assessments. In spite of noteworthy differences in the sampling protocols, the soil parameters chosen as explanatory variables, and the methods used to evaluate the site-specific initial concentrations, most investigations undoubtedly evidenced a significant accumulation of metals and/or hydrocarbons in SUDS soils, which in the majority of the cases appears to be restricted to the upper 10 to 30cm. These results may suggest that SUDS exhibit an interesting potential for pollution control, but antinomic observations have also been made in several specific cases, and the inter-site concentration variability is still difficult to appraise. There seems to be no consensus regarding the level of complexity to be used in models. However, the available data deriving from experimental studies is generally limited to the contamination profiles and a few parameters of the soil, as a result of which "complex" models (including colloid-facilitated transport for example) appear to be difficult to validate before using them for predictive evaluations.

    Full Text Available Technologies influencing alternative means of transportation have been expanding in recent years due to increasing urbanization and motorization. In this paper, a solar powered electric auto-rickshaw (SPEA is designed and developed for Indian conditions. The vehicle developed is comprehensively analyzed techno-economically for its viability in the Indian market. The performance analysis of SPEA results in an optimal charging rate of 2 kWh per day with an average solar irradiance of 325 W/m2 on a typical sunny day. The discharging characteristics are studied based on different loading conditions. The vehicle achieved a maximum speed of 21.69 km/h with battery discharge rate of 296 W at 90 kg load and also reached a maximum discharge rate of 540 W at 390 kg loading with a maximum speed of 12.11 km/h. Environmental analysis of SPEA indicated that the yearly CO2 emissions of 1777 kg, 1987 kg and 1938 kg from using Compressed Natural Gas, Liquefied Petroleum Gas and gasoline engines respectively can be mitigated using SPEA. The financial analysis of SPEA concluded that the investor’s payback duration is 24.44% less compared to a gasoline-run vehicle. Socio-Economic analysis of SPEA discussed its significant advantages and showed 15.74% and 0.85% increase in yearly income over gasoline driven and battery driven vehicles.

    Full Text Available Sustainability responses must accelerate to avoid major risks to cities. Climate change impact on cities, likely to be significant if global sustainability initiatives are not quickened, is a paramount example of the risk. World wide meetings of city planning practitioners and researchers agree that an urgent agenda is to work together to empower cities and their governments with funds, tools and mentoring to make the responses needed. In the spirit of this urgent agenda, this paper introduces some practical methods for assessing sustainability associated with transport and urban form in our cities. A concept of strategic scans of future scenarios, which underpins the backcasting approach, has been introduced at the 12 th World Conference on Transport Research (WCTR in 2010 and has broken urban and transport planning trend. These strategic scans are based on a sustainability framework, the elements of which provide evidence based drivers of sustainability. The framework culminates in metric visualisations for each of the three pillars of sustainability. The paper details some of the operational aspects of these metrics in the form of environmental sustainability-accessibility space, putting into practice measures of environmental stewardship, social equity, economic efficiency, and the relationship among them. The paper concludes with a call of developing a typology of sustainability performance using the strategic scan methodology to extend the principles of the methodology into a useful tool for city governments and contribute to assembling a daTablease of city forms, transport structures, and their sustainability performances.

    The STEEP STREAMS (Solid Transport Evaluation and Efficiency in Prevention: Sustainable Techniques of Rational Engineering and Advanced MethodS) project consists of a collaboration among the Universities of Trento, Uppsala and Lisbon, who joined in a consortium within the ERANET Water JPI call WaterWorks2014. The aim of the project is to produce new rational criteria for the design of protection works against debris flows, a phenomenon consisting in hyper-concentrated flows of water and sediments, classified as catastrophic events typical of small mountainous basins (area climate change. In this context, one of the key challenges of this project is the use of comparatively coarse RCM projections to the small catchments examined in STEEP STREAMS. Given these changes, conventional protection works and their design criteria may not suffice to provide adequate levels of protection to human life and urban settlements. These structures create a storage area upstream the alluvial fans and the settlements, thereby reducing the need of channelization in areas often constrained by urban regulations. To optimize the lamination, and in particular to reduce the peak of solid mass flux, it is necessary that the deposition basin is controlled by a slit check dam, capable of inducing a controlled sedimentation of the solid mas flux. In order to achieve that, reliable design tools are needed. Driftwood represents another important factor increasing the risk, as clogging induced by the vegetal material represents a major problem for the operational reliability of slit check dams. Current procedures in compiling hazardous maps do not account for such effects. The STEEPS STREAMS project aims at developing structural innovative solutions and design criteria reliable to mitigate the impacts of flash floods and debris flows especially in presence of intense woody material transport, typical of mountain catchments.

    We study the impact of brine acidity and initial pore structure on the dynamics of fluid/solid reaction at high Péclet numbers and low Damköhler numbers. A laboratory μ-CT scanner was used to image the dissolution of Ketton, Estaillades, and Portland limestones in the presence of CO2-acidified brine at reservoir conditions (10 MPa and 50 °C) at two injected acid strengths for a period of 4 h. Each sample was scanned between 6 and 10 times at ∼4 μm resolution and multiple effluent samples were extracted. The images were used as inputs into flow simulations, and analysed for dynamic changes in porosity, permeability, and reaction rate. Additionally, the effluent samples were used to verify the image-measured porosity changes. We find that initial brine acidity and pore structure determine the type of dissolution. Dissolution is either uniform where the porosity increases evenly both spatially and temporally, or occurs as channelling where the porosity increase is concentrated in preferential flow paths. Ketton, which has a relatively homogeneous pore structure, dissolved uniformly at pH = 3.6 but showed more channelized flow at pH = 3.1. In Estaillades and Portland, increasingly complex carbonates, channelized flow was observed at both acidities with the channel forming faster at lower pH. It was found that the effluent pH, which is higher than that injected, is a reasonably good indicator of effective reaction rate during uniform dissolution, but a poor indicator during channelling. The overall effective reaction rate was up to 18 times lower than the batch reaction rate measured on a flat surface at the effluent pH, with the lowest reaction rates in the samples with the most channelized flow, confirming that transport limitations are the dominant mechanism in determining reaction dynamics at the fluid/solid boundary.

  19. Sustainable Vehicles-Based Alternatives in Last Mile Distribution of Urban Freight Transport: A Systematic Literature Review

    2017-07-01

    Full Text Available The advent of new technologies in last mile deliveries is about to cause a disruption in the traditional business model applied in urban cargo transportation, thus presenting innumerous research opportunities in this field of knowledge. In this context, identifying new operation models and vehicles that could be applied for last mile deliveries in urban areas becomes crucial. Therefore, this paper aims to identify, through a systematic literature review, the main types of vehicles addressed in the literature that could be used in the last mile of urban freight distribution in order to increase the sustainability of this type of operation. The results indicate a trend for the implementation of smaller and lighter vehicles for last mile deliveries in urban areas: 47% of the studies suggest, among other alternatives, the use of bicycles and tricycles; while 53% of the articles support the use of light commercial vehicles. Another trend observed in this type of distribution, indicated in 64% of the studies, is the shift from conventional (fossil fuels to alternative sources of energy (electricity.

  3. Modeling the downward transport of 210Pb in Peatlands: Initial Penetration‐Constant Rate of Supply (IP-CRS) model

    2016-01-01

    The vertical distribution of 210 Pb is commonly used to date peat deposits accumulated over the last 100–150 years. However, several studies have questioned this method because of an apparent post-depositional mobility of 210 Pb within some peat profiles. In this study, we introduce the Initial Penetration–Constant Rate of Supply (IP-CRS) model for calculating ages derived from 210 Pb profiles that are altered by an initial migration of the radionuclide. This new, two-phased, model describes the distribution of atmospheric-derived 210 Pb ( 210 Pb xs ) in peat taking into account both incorporation of 210 Pb into the accumulating peat matrix as well as an initial flushing of 210 Pb through the uppermost peat layers. The validity of the IP-CRS model is tested in four anomalous 210 Pb peat records that showed some deviations from the typical exponential decay profile not explained by variations in peat accumulation rates. Unlike the most commonly used 210 Pb-dating model (Constant Rate of Supply (CRS)), the IP-CRS model estimates peat accumulation rates consistent with typical growth rates for peatlands from the same areas. Confidence in the IP-CRS chronology is also provided by the good agreement with independent chronological markers (i.e. 241 Am and 137 Cs). Our results showed that the IP-CRS can provide chronologies from peat records where 210 Pb mobility is evident, being a valuable tool for studies reconstructing past environmental changes using peat archives during the Anthropocene. - Highlights: • Accurate age dating of peat and sediment cores is critical for evaluating change. • A new 210 Pb dating model that includes vertical transport of 210 Pb was developed. • The IP-CRS model provided consistent peat accumulation rates. • The IP-CRS ages were consistent with independent chronological markers. • The IP-CRS model derives peat ages where downward 210 Pb transport is evidenced.

    The boundary of the target hepatic segment within the liver parenchyma cannot be marked by the use of a conventional anatomic hepatectomy approach. This study describes a novel methylene blue staining technique for guiding the anatomic resection of hepatocellular carcinoma (HCC). Between February 2009 and February 2012, anatomic hepatectomy was performed in 106 patients with HCC via a novel, sustained methylene blue staining technique. Sustained staining was achieved by injecting methylene blue into the distal aspect of the portal vein after exposing Glisson's sheath. The hepatic pedicle was immediately ligated, and the hepatic parenchymal transection was performed along the interface between methylene blue stained tissue and unstained tissue. Anatomic hepatectomies included subsegmentectomy (n = 16), monosegmentectomy (n = 57), multisegmentectomy (n = 27), and hemihepatectomy (n = 6). The portal vein was injected successfully with methylene blue in 100% of cases, and complete staining of the target hepatic segment was achieved in 98 of 106 (92.5%) cases. Mean intraoperative bleeding was 360 ± 90 mL, and the postoperative complication rate was 24.5% (26/106). No perioperative mortality occurred. Operative margins were all negative on pathologic examination. Mean duration of postoperative follow-up was 40 months (range, 24-60). No local recurrence (around the operative margin) occurred. This novel technique of achieving sustained staining by injecting methylene blue then immediately ligating the hepatic pedicle is simple and feasible. It can guide the selection of the operative margin during hepatic parenchyma transection to improve the accuracy of anatomic hepatectomy for the treatment of HCC. Copyright © 2015 Elsevier Inc.

    2008-01-01

    Over the past 50 years, the National Aeronautics and Space Administration (NASA) has delivered space transportation solutions for America's complex missions, ranging from scientific payloads that expand knowledge, such as the Hubble Space Telescope, to astronauts and lunar rovers destined for voyages to the Moon. Currently, the venerable Space Shuttle, which has been in service since 1981, provides the United States' (U.S.) capability for both crew and heavy cargo to low-Earth orbit to' construct the International Space Station, before the Shuttle is retired in 2010. In the next decade, NASA will replace this system with a duo of launch vehicles: the Ares I Crew Launch Vehicle and the Ares V Cargo Launch Vehicle (Figure 1). The goals for this new system include increased safety and reliability coupled with lower operations costs that promote sustainable space exploration for decades to come. The Ares I will loft the Orion Crew Exploration Vehicle, while the heavy-lift Ares V will carry the Altair Lunar Lander and the equipment and supplies needed to construct a lunar outpost for a new generation of human and robotic space pioneers. This paper will provide details of the in-house systems engineering and vehicle integration work now being performed for the Ares I and planned for the Ares V. It will give an overview of the Ares I system-level test activities, such as the ground vibration testing that will be conducted in the Marshall Center's Dynamic Test Stand to verify the integrated vehicle stack's structural integrity and to validate computer modeling and simulation (Figure 2), as well as the main propulsion test article analysis to be conducted in the Static Test Stand. These activities also will help prove and refine mission concepts of operation, while supporting the spectrum of design and development work being performed by Marshall's Engineering Directorate, ranging from launch vehicles and lunar rovers to scientific spacecraft and associated experiments

  8. An Integrated Approach on Groundwater Flow and Heat/Solute Transport for Sustainable Groundwater Source Heat Pump (GWHP) System Operation

    The GWHP system uses a stable temperature of groundwater for cooling and heating in buildings and thus has been known as one of the most energy-saving and cost-efficient renewable energy techniques. A GWHP facility was installed at an island located at the confluence of North Han and South Han rivers, Korea. Because of well-developed alluvium, the aquifer is suitable for application of this system, extracting and injecting a large amount of groundwater. However, the numerical experiments under various operational conditions showed that it could be vulnerable to thermal interference due to the highly permeable gravel layer, as a preferential path of thermal plume migration, and limited space for well installation. Thus, regional groundwater flow must be an important factor of consideration for the efficient operation under these conditions but was found to be not simple in this site. While the groundwater level in this site totally depends on the river stage control of Paldang dam, the direction and velocity of the regional groundwater flow, observed using the colloidal borescope, have been changed hour by hour with the combined flows of both the rivers. During the pumping and injection tests, the water discharges in Cheongpyeong dam affected their respective results. Moreover, the measured NO3-N concentrations might imply the effect of agricultural activities around the facility on the groundwater quality along the regional flow. It is obvious that the extraction and injection of groundwater during the facility operation will affect the fate of the agricultural contaminants. Particularly, the gravel layer must also be a main path for contaminant migration. The simulations for contaminant transport during the facility operation showed that the operation strategy for only thermal efficiency could be unsafe and unstable in respect of groundwater quality. All these results concluded that the integrated approach on groundwater flow and heat/solute transport is necessary

  9. Control of the initiation and termination of kinesin-1-driven transport by myosin-Ic and nonmuscle tropomyosin.

    Intracellular transport is largely driven by processive microtubule- and actin-based molecular motors. Nonprocessive motors have also been localized to trafficking cargos, but their roles are not well understood. Myosin-Ic (Myo1c), a nonprocessive actin motor, functions in a variety of exocytic events, although the underlying mechanisms are not yet clear. To investigate the interplay between myosin-I and the canonical long-distance transport motor kinesin-1, we attached both motor types to lipid membrane-coated bead cargo, using an attachment strategy that allows motors to actively reorganize within the membrane in response to the local cytoskeletal environment. We compared the motility of kinesin-1-driven cargos in the absence and presence of Myo1c at engineered actin/microtubule intersections. We found that Myo1c significantly increases the frequency of kinesin-1-driven microtubule-based runs that begin at actin/microtubule intersections. Myo1c also regulates the termination of processive runs. Beads with both motors bound have a significantly higher probability of pausing at actin/microtubule intersections, remaining tethered for an average of 20 s, with some pauses lasting longer than 200 s. The actin-binding protein nonmuscle tropomyosin (Tm) provides spatially specific regulation of interactions between myosin motors and actin filaments in vivo; in the crossed-filament in vitro assay, we found that Tm2-actin abolishes Myo1c-specific effects on both run initiation and run termination. Together, these observations suggest Myo1c is important for the selective initiation and termination of kinesin-1-driven runs along microtubules at specific actin filament populations within the cell.

    Elevated concentrations of radioactivity from the Chernobyl accident were encountered in the surface air over the United States along the east coast and in the north-west on 9 and 10 May 1986. The nearly simultaneous arrival of radioactive debris at widely separated locations resulted from different paths being taken by the debris released at different times during the course of the accident. Debris released during the explosion at the Chernobyl reactor was transported across the Arctic, within the lower troposphere, and zonally across Asia and the North Pacific Ocean, within the mid-troposphere. This debris descended into the planetary boundary layer along the east coast of the US. The descent was associated with a quasi-stationary cyclone located over the western North Atlantic Ocean. Debris that had a different composition of radioactivity was released from the damaged reactor during the week immediately following the initial explosion. This debris was then transported zonally across Asia and the North Pacific Ocean within the planetary boundary layer and lower troposphere and was swept into the north-western US. (author)

  11. Interaction of reactive fronts during transport in a homogeneous porous medium with initial small non-uniformity.

    A reactive fluid circulating within a porous medium can dissolve minerals with which it is out of equilibrium and modify the porosity and permeability. The positive feedback between fluid transport and mineral dissolution causes complex reaction front morphologies such as fingers or wormholes. This study presents a numerical model to investigate reaction front instability, temporal aquifer porosity, and species concentration evolution during reactive transport in a homogeneous porous medium with two small, initially local non-uniformities. Simulation results indicate that a stable planar front develops for a small upstream pressure gradient while the growth of two non-uniformities becomes unstable for a large upstream pressure gradient. Moreover, the unstable reaction front may be either double- or single-finger in shape. Reaction front shape selection depends on the spacing of the two local non-uniformities and the upstream pressure gradients. A behavior diagram is constructed to identify a planar, single- or double-front morphology. The critical non-uniformities spacing at which a reaction front begins to merge into a single-finger decreases with increasing upstream pressure gradient.

    The PLX- α project is studying plasma liner formation and implosion by merging a spherical array of plasma jets as a standoff driver for magneto-inertial fusion (MIF). A three-dimensional smoothed particle hydrodynamics (SPFMax) code is used to conduct simulations of merging of discrete plasma jets to form a plasma liner and the subsequent implosion of that liner. Peak ram pressure, Mach number, and uniformity of the liner are presented as a function of initial jet properties and assumptions about transport physics. The initial conditions include the number of jets, density, temperature, and implosion velocity. Solid-angle-averaged and standard deviation of liner ram pressure and Mach number reveal variations during liner formation and implosion. Spherical-harmonic mode-number analysis of spherical slices of ram pressure at various radii and times provide a quantitative means to assess the evolution of liner non-uniformity. Comparisons are made with select and equivalent cases of a uniform, imploding liner. Simulations of 6 and 7 jets are provided for select cases to support near-term experiments on PLX- α and will include synthetic spectra and line-integrated densities.

    Addressing global health disparities in the developing world gained prominence during the first decade of the twenty-first century. The HIV/AIDS epidemic triggered much interest in and funding for health improvement and mortality reduction in low- and middle-income nations, particularly in sub-Saharan Africa. Alliances between U.S. academic medical centers and African nations were created through the departments of internal medicine and infectious disease. However, the importance of addressing surgical disease as part of global public health is becoming recognized as part of international health development efforts. We propose a novel model to reduce the global burden of surgical diseases in resource poor settings by incorporating a sustained institutional surgical presence with our residency training experience by placing a senior surgical resident to provide continuity of care and facilitate training of local personnel. We present the experiences of the University of North Carolina (UNC) Department of Surgery as part of the UNC Project in Malawi as an example of this innovative approach.
